UBS BOND FUND
INVESTORS FOR WHOM THE FUND IS DESIGNED
 
UBS  Bond Fund  (the '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 Fund seeks to achieve  its
investment  objective  by investing  all of  its investable  assets in  UBS Bond
Portfolio  (the  'Portfolio').  The  Portfolio  is  a  series  of  UBS  Investor
Portfolios  Trust (the 'Trust'), an  open-end management investment company. The
Portfolio has the same investment objective as the Fund. Because the  investment
characteristics  and experience of the Fund  will correspond directly with those
of the Portfolio, the discussion in  this Prospectus focuses on the  investments
and  investment policies of the Portfolio. The  net asset value of shares of the
Fund fluctuates with changes in the  value of the investments in the  Portfolio.
See 'Investment Objective and Policies -- Quality Information.'
 
The  Portfolio may make  various types of investments  in seeking its objective.
Among  the  permissible  investments  for  the  Portfolio  are  bonds  and  debt
instruments  of domestic and foreign companies. The 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 Objective and Policies' discussed
below.
 
The  minimum initial investment in the Fund  is $25,000, except that the minimum
initial investment is $10,000 for shareholders of another series of UBS  Private
Investor  Funds, Inc. (the 'Company'). The minimum subsequent investment for all
investors is $5,000. These minimums may be waived at the Fund's discretion.  See
'Purchase of Shares.' If shareholders reduce their total investment in shares of
the  Fund to less  than $10,000, their  investment will be  subject to mandatory
redemption. See 'Redemption of Shares -- Mandatory Redemption.' The Fund is  one
of  several series  of the  Company, an  open-end management  investment company
organized as a Maryland corporation.
 
This  Prospectus  describes  the  Fund's  investment  objective  and   policies,
management  and operations to enable investors to decide if the Fund suits their
investment needs. The Fund operates through a two-tier master-feeder  investment
fund  structure.  The  Company's  Board of  Directors  (the  'Directors'  or the
'Board') believes  that  this  structure provides  Fund  shareholders  with  the
opportunity  to  achieve  certain economies  of  scale that  would  otherwise be
unavailable  if  the  shareholders'  investments  were  not  pooled  with  other
investors sharing similar investment objectives.
 
The  following  table  illustrates  that  Fund  investors  incur  no shareholder
transaction expenses: their  investments in  the Fund  are subject  only to  the
operating  expenses  set  forth below  for  the  Fund and  the  Portfolio,  as a
percentage of average daily net assets  of the Fund. The Directors believe  that
the  aggregate  per  share  expenses  of the  Fund  and  the  Portfolio  will be
approximately equal to and  may be less  than the expenses  that the Fund  would
incur  if it  retained the  services of an  investment adviser  and invested its
assets directly  in  portfolio  securities.  Fund  and  Portfolio  expenses  are
discussed  below under  the headings  'Management', 'Expenses'  and 'Shareholder
Services.'

*    Expenses are  expressed as  a percentage of  the Fund's  average daily  net
assets  and are based on  the expenses incurred during  the period April 2, 1996
(commencement of operations) through December 31, 1996, after any applicable fee
waivers and  expense  reimbursements.  Without  such  fee  waivers  and  expense
reimbursements,  Total Operating Expenses would be equal, on an annual basis, to
4.13% of the Fund's average daily net assets. See 'Management.'
    
 
**   The New  York Branch  (the  'Branch' or  the 'Adviser')  of Union  Bank  of
Switzerland (the 'Bank') has agreed to waive fees and reimburse the Fund for any
of its operating expenses to the extent that the Fund's total operating expenses
(including  its share of  the Portfolio's expenses) exceed,  on an annual basis,
0.80% of  the  Fund's  average  daily  net assets.  The  Branch  may  modify  or
discontinue  this undertaking  at any  time in  the future  with 30  days' prior
notice to the Fund. The  Portfolio's advisory fee would  be equal, on an  annual
basis,  to 0.45% of the average daily net  assets of the Portfolio if there were
no fee waiver in  effect. See 'Management --  Adviser and Funds Services  Agent'
and 'Expenses.'
 
***  The fees and expenses  in Other Expenses include  fees payable to Signature
Broker-Dealer Services,  Inc.  ('Signature') under  an  Administrative  Services
Agreement  with  the  Fund, fees  payable  to Signature  Financial  Group (Grand
Cayman) Ltd.  ('Signature-Cayman') under  an Administrative  Services  Agreement
with  the  Portfolio,  fees  payable  to Investors  Bank  &  Trust  Company (the
'Custodian' or the 'Transfer Agent') as custodian of the Fund and the  Portfolio
and  transfer  agent of  the  Fund, and  fees payable  by  the Fund  to Eligible
Institutions providing shareholder services under various shareholder  servicing
agreements.  For a  more detailed  description of  contractual fee arrangements,
including fee waivers and expense reimbursements,  and of the fees and  expenses
included in Other Expenses, see 'Management' and 'Shareholder Services.'

HISTORICAL PERFORMANCE OF COMPARABLE DISCRETIONARY ACCOUNTS. The following table
sets  forth (i) the composite  average annual total returns  for the one, three,
five and ten year periods ended December 31, 1996 for all discretionary accounts
described below that  have been managed  for at  least one full  quarter by  UBS
Asset  Management (New York) Inc., a wholly-owned subsidiary of the Bank ('UBSAM
NY'), (ii) the average annual total return for the Fund for the period April  2,
1996  (commencement  of operations)  through December  31,  1996, and  (iii) the
average  annual  total   return  during   the  same  periods   for  the   Lehman
Government/Corporate   Intermediate  Bond  Index.   The  discretionary  accounts
described in  (i) above  have substantially  the same  investment objective  and
policies  and are managed in  a manner substantially the  same as the Portfolio.
While the  Portfolio  will be  managed  by the  Branch,  the management  of  the
Portfolio  will be substantially the same as by UBSAM NY and will be carried out
by personnel  who performed  these services  for the  discretionary accounts  at
UBSAM  NY, who will  be employed by  the Branch for  this purpose. The composite
total returns for such accounts have been  adjusted to deduct all of the  Fund's
annual  total operating  expenses of  0.80% of average  daily net  assets as set
forth in the Fee Table above. The composite total returns are time-weighted  and
weighted  by individual account  size and reflect  the reinvestment of interest.
The discretionary accounts  are not subject  to certain investment  limitations,
diversification   requirements  and   other  restrictions   imposed  by  federal
securities and tax laws on the Portfolio  that, if applied to the accounts,  may
have  adversely affected their performance  results. The composite total returns
of these discretionary accounts does not represent the historical performance of
the Portfolio and should not be viewed as a prediction of future performance  of
the Portfolio. Lehman Government/Corporate Intermediate Bond Index (the 'Index')

MASTER-FEEDER STRUCTURE
 
Unlike  other mutual funds that directly  acquire and manage their own portfolio
of securities, the Fund seeks to  achieve its investment objective by  investing
all  of its  investable assets in  the Portfolio, a  separate investment company
with the same investment objective as the Fund. The investment objective of  the
Fund and the Portfolio may be changed only with the approval of the holders of a
majority  of the outstanding voting securities of  the Fund or a majority of the
investors in the Portfolio, respectively, after 30 days' prior notice.
 
This  master-feeder  structure  has  been  developed  relatively  recently,   so
shareholders should carefully consider this investment approach.
 
In  addition to selling an interest in  the Portfolio to the Fund, the Portfolio
may sell  interests in  the Portfolio  to other  mutual funds  or  institutional
investors.  Such investors will  invest in the  Portfolio on the  same terms and
conditions as the  Fund and will  pay a proportionate  share of the  Portfolio's
expenses.  However, other entities investing in the Portfolio may sell shares of
their own  fund  using a  different  pricing  structure than  the  Fund's.  Such
different pricing structures may result in differences in returns experienced by
investors  in  other funds  that invest  in the  Portfolio. Such  differences in
returns are  not uncommon  and  are present  in  other mutual  fund  structures.
Information  concerning other holders of interests in the Portfolio is available
from Signature at (617) 423-0800.
 
The Fund may withdraw its investment in  the Portfolio at any time if the  Board
determines  that it  is in  the Fund's  best interest  to do  so. Upon  any such
withdrawal, the Board would consider what  action might be taken, including  the
investment  of all the Fund's assets  in another pooled investment entity having
the same investment objective and restrictions  as the Fund or the retaining  of
an  investment  adviser  to manage  the  Fund's  assets in  accordance  with the
investment policies described below with respect to the Portfolio.
 
Certain  changes   in  the   Portfolio's  investment   objective,  policies   or
restrictions, or a failure by the Fund's shareholders to approve a change in the
Portfolio's  investment  objective  or  restrictions, may  require  the  Fund to
withdraw its investments in the Portfolio.  Any such withdrawal could result  in
an   in-kind  distribution  of  portfolio  securities  (as  opposed  to  a  cash
distribution) by  the  Portfolio  to  the  Fund.  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 the Fund's having a
less diversified  portfolio  of  investments  or  adversely  affect  the  Fund's
liquidity,  and  the  Fund  could  incur  brokerage,  tax  or  other  charges in
converting such securities to cash.  Notwithstanding the above, there are  other
means for meeting shareholder redemption requests, such as borrowing.
 
Smaller  funds  investing in  the Portfolio  may be  materially affected  by the
actions of larger funds investing in the Portfolio. For example, if a large fund
withdraws from the  Portfolio, the remaining  funds may subsequently  experience
higher  pro  rata operating  expenses,  thereby lowering  returns. Additionally,
because the  Portfolio would  become smaller,  it may  become less  diversified,
resulting  in potentially increased portfolio risk (however, these possibilities
also exist for traditionally structured  funds that have large or  institutional
investors  who may withdraw  from a fund).  Also, funds with  a greater pro rata
ownership  in  the  Portfolio  could  have  effective  voting  control  of   its
operations. Except as permitted by
                                      -5-



<PAGE>
the  Securities  and   Exchange  Commission  (the'SEC'),  whenever  the  Fund is
requested to vote  on matters  pertaining to  the Portfolio,  the  Company  will
hold   a  meeting  of   Fund  shareholders  and  will  cast  all  of  its  votes
proportionately as  instructed by the Fund's shareholders. See 'Organization' in
the  SAI. Fund  shareholders who do not vote will not affect the Fund's votes at
the Portfolio meeting.  The percentage of  the Company's votes representing Fund
shareholders not  voting will be voted  by the Company in the same proportion as
the Fund shareholders who do, in fact, vote.
 
For  more information about  the Portfolio's investment  objective, policies and
restrictions, see 'Investment  Objective and  Policies', 'Additional  Investment
Information   and  Risk   Factors'  and  'Investment   Restrictions'.  For  more
information about the Portfolio's management and expenses, see 'Management'. For
more  information  about  changing   the  investment  objective,  policies   and
restrictions of the Fund or the Portfolio, see 'Investment Restrictions'.
 
INVESTMENT OBJECTIVE AND POLICIES
 
The  investment  objective of  the Fund  and the  Portfolio is  described below,
together with  the policies  each  employs to  seek  to achieve  its  objective.
Additional  information  about  the  investment policies  of  the  Fund  and the
Portfolio appears in  the SAI  under 'Investment Objectives  and Policies.'  The
Fund seeks to achieve its objective by investing all of its investable assets in
the Portfolio, which has the same investment objective as the Fund. There can be
no  assurance that the investment objective of the Fund or the Portfolio will be
achieved.
 
The objective  of  the 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  Portfolio will  fluctuate, the
Portfolio attempts  to preserve  the  value of  its  investments to  the  extent
consistent with its investment objective.
 
The  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 Fund may also be a convenient way to add fixed income  exposure
to diversify an investor's existing portfolio.
 
The  Adviser  actively manages  the  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 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 Portfolio's assets among  the 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 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 1% change in  yield will result in a 4% change  in
price  in  the  opposite  direction. The  Portfolio's  benchmark  is  the Lehman
Government/Corporate Intermediate Bond Index, which currently has a duration  of
approximately  3.28 years. The Portfolio intends  to have a duration between 0.5
years
 
                                      -6-



<PAGE>
shorter  and  0.5  years  longer  than  its  benchmark.  The  maturities  of the
Portfolio's individual securities  may vary widely  from its duration,  however,
and may be as long as 30 years.
 
The  Portfolio  intends to  manage  its securities  actively  in pursuit  of its
investment objective.  Portfolio  transactions  are  undertaken  principally  to
accomplish  the Portfolio's objective  in relation to  expected movements in the
general level of interest rates, but the Portfolio may also engage in short-term
trading consistent with its  objective. To the extent  the Portfolio engages  in
short-term trading, it may incur increased transaction costs. See 'Taxes' below.
The annual portfolio turnover rate for the Fund is expected to be under 100%.
 
CORPORATE BONDS. The Portfolio may invest in a broad range of corporate bonds of
domestic and foreign issuers. These include debt securities of various types and
maturities,  e.g.,  debentures,  notes,  mortgage  securities,  equipment  trust
certificates and  other collateralized  securities and  zero coupon  securities.
Collateralized  securities  are backed  by a  pool  of assets  such as  loans or
receivables that generate cash flow to cover the payments due on the securities.
Collateralized securities are subject to  certain risks, including a decline  in
the  value of the collateral backing the  security, failure of the collateral to
generate the anticipated  cash flow or  in certain cases  more rapid  prepayment
than anticipated because of events affecting the collateral, such as accelerated
prepayment  of mortgages or other loans  backing these securities or destruction
of equipment subject to equipment trust  certificates. In the event of any  such
prepayment,  the  Portfolio  will  be  required  to  reinvest  the  proceeds  of
prepayments at interest rates prevailing at the time of reinvestment, which  may
be  lower than the  interest rates on  the prepaid securities.  In addition, the
value of zero  coupon securities, which  do not pay  interest, is more  volatile
than  that of interest bearing debt  securities with the same maturity. Although
zero coupon  securities do  not pay  interest to  the holders  thereof,  federal
income  tax law  requires the  Fund to recognize  a portion  of such securities'
discount as income each  year. This income must  be distributed to  shareholders
along  with other income earned by  the Fund. See 'Dividends and Distributions.'
The Portfolio does  not intend to  invest in common  stock but may  invest to  a
limited  degree in convertible debt or  preferred stocks. The Portfolio does not
expect to invest  more than 25%  of its  total assets in  securities of  foreign
issuers.  If the Portfolio invests in non-U.S. dollar denominated securities, it
may hedge its foreign currency exposure. The Portfolio may purchase  nonpublicly
offered  debt securities. See 'Illiquid  Investments; Privately Placed and Other
Unregistered  Securities.'  See  'Additional  Investment  Information  and  Risk
Factors'   for  further  information  on  foreign  investments  and  convertible
securities.
 
GOVERNMENT OBLIGATIONS.  The  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
Portfolio's positions  in  these  securities  and  requiring  the  Portfolio  to
reinvest   the  prepayments  at  interest  rates   prevailing  at  the  time  of
reinvestment. The Portfolio may also invest in obligations issued or  guaranteed
by  U.S. Government agencies or instrumentalities  where the 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 Portfolio's investments in government securities.
 
The  Portfolio may  also invest in  municipal obligations, which  may be general
obligations of  the  issuer  or  payable only  from  specific  revenue  sources.
However,  the 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 Portfolio  may invest  in debt  securities of
foreign  governments  and  governmental  entities.  See  'Additional  Investment
Information and Risk Factors' for further information on foreign investments.
 
                                      -7-
 


<PAGE>
MONEY MARKET INSTRUMENTS. The Portfolio may purchase money market instruments to
invest  temporary cash  balances or to  maintain liquidity  to meet withdrawals.
However,  the  Portfolio  may  also  invest,  without  limit,  in  money  market
instruments  as a temporary  defensive measure taken  during, or in anticipation
of, adverse market conditions.  The money market  investments permitted for  the
Portfolio  include  obligations  of the  U.S.  Government and  its  agencies and
instrumentalities, other debt securities, commercial paper, bank obligations and
repurchase agreements. For  more detailed information  about these money  market
investments, see 'Investment Objectives and Policies' in the SAI.
 
QUALITY  INFORMATION. It is a current policy  of the Portfolio that under normal
circumstances at least sixty-five percent (65%) of its investment in bonds  will
consist  of securities that are  rated at least A  by Moody's Investors Service,
Inc. ('Moody's') or Standard & Poor's Corporation ('Standard & Poor's') or  that
are unrated and in the Adviser's opinion are of comparable quality. Up to thirty
percent  (30%) of the Portfolio's bonds may consist of debt securities rated Baa
or better by Moody's or BBB or better by Standard & Poor's or are unrated and in
the Adviser's opinion are of comparable quality. Up to five percent (5%) of  the
Portfolio's bonds may be invested in debt securities that are rated Ba or better
by  Moody's or  BB or  better by  Standard &  Poor's or  are unrated  and in the
Adviser's opinion are of comparable quality. Securities rated Baa by Moody's  or
BBB  by  Standard  &  Poor's  are considered  investment  grade,  but  have some
speculative characteristics. Securities rated Ba by Moody's or BB by Standard  &
Poor's  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
Portfolio may continue to hold the investment.
 
The Portfolio may also purchase obligations on a when-issued or delayed delivery
basis,  enter  into  repurchase  and reverse  repurchase  agreements,  engage in
mortgage dollar  roll  transactions,  loan its  portfolio  securities,  purchase
certain  privately placed securities and enter into certain hedging transactions
that may involve options on securities and securities indices, futures contracts
and options on  futures contracts.  For a  discussion of  these investments  and
investment techniques, see 'Additional Investment Information and Risk Factors.'
 
ADDITIONAL INVESTMENT INFORMATION AND RISK FACTORS
 
CONVERTIBLE  SECURITIES. The convertible  securities in which  the Portfolio may
invest include any  debt securities or  preferred stocks that  may be  converted
into  common stock or that carry the right to purchase common stock. Convertible
securities entitle the holder to exchange the securities for a specified  number
of  shares of  common stock,  usually of the  same company,  at specified prices
within a certain period of time.
 
WHEN-ISSUED  AND  DELAYED  DELIVERY  SECURITIES.  The  Portfolio  may   purchase
securities  on a when-issued or delayed  delivery basis. Delivery of and payment
for these securities may take as long as  a month or more after the date of  the
purchase  commitment.  The  value  of  these  securities  is  subject  to market
fluctuation during  this  period  and  no interest  or  income  accrues  to  the
Portfolio  until settlement. At  the time of  settlement, a when-issued security
may be valued at less than its purchase price. Between the trade and  settlement
dates,  the  Portfolio will  maintain a  segregated  account with  the Custodian
consisting of a portfolio of high grade, liquid debt securities with a value  at
least  equal to these  commitments. When entering into  a when-issued or delayed
delivery transaction, the Portfolio will rely  on the other party to  consummate
the  transaction;  if the  other  party fails  to do  so,  the Portfolio  may be
disadvantaged. It  is the  current policy  of the  Portfolio not  to enter  into
when-issued  commitments exceeding in  the aggregate 15% of  the market value of
the Portfolio's total assets less liabilities (excluding the obligations created
by these commitments).
 
REPURCHASE  AGREEMENTS.  The  Portfolio  may  engage  in  repurchase   agreement
transactions  with brokers,  dealers or  banks that  meet the  credit guidelines
approved by the  Trust's Board  of Trustees  (the 'Trustees').  In a  repurchase
agreement,  the  Portfolio buys  a security  from  a seller  that has  agreed to
repurchase it at a mutually agreed upon date and price, reflecting the  interest
rate  effective for the term  of the agreement. The  term of these agreements is
usually from overnight to one  week. A repurchase agreement  may be viewed as  a
fully collateralized loan of money by the Portfolio to the seller. The Portfolio
always  receives securities as collateral with a  market value at least equal to
the purchase price plus accrued interest and this value is maintained during the
term of the agreement. If the seller defaults
 
                                      -8-
 


<PAGE>
and the  collateral's value  declines,  the Portfolio  might  incur a  loss.  If
bankruptcy proceedings are commenced with respect to the seller, the Portfolio's
realization  upon  the  disposition of  collateral  may be  delayed  or limited.
Investments in  repurchase  agreements maturing  in  more than  seven  days  and
certain  other  investments that  may be  considered  illiquid are  limited. See
'Illiquid Investments;  Privately  Placed  and  Other  Unregistered  Securities'
below.
 
REVERSE  REPURCHASE AGREEMENTS. The Portfolio is permitted to enter into reverse
repurchase agreements. In a reverse repurchase agreement, the Portfolio sells  a
security  and agrees to repurchase it at  a mutually agreed upon date and price,
reflecting the interest  rate effective for  the term of  the agreement. It  may
also  be viewed as the borrowing of money  by the Portfolio and, therefore, is a
form of leverage. Leverage may cause any gains or losses of the Portfolio to  be
magnified.  For more  information, including limitations  on the  use of reverse
repurchase agreements, see 'Investment Objectives  and Policies' in the SAI  and
'Investment Restrictions' below.
 
SECURITIES LENDING. Subject to applicable investment restrictions, the Portfolio
may lend its securities. The Portfolio may lend its securities if such loans are
secured  continuously by cash or equivalent collateral  or by a letter of credit
in favor of  the Portfolio at  least equal at  all times to  100% of the  market
value of the securities loaned, plus accrued interest. While such securities are
on  loan, the borrower will pay the Portfolio any income accruing thereon. Loans
will be subject to termination by  the Portfolio in the normal settlement  time,
generally  three business  days after  notice, or by  the borrower  on one day's
notice. Borrowed securities must  be returned when the  loan is terminated.  Any
gain  or loss in the market price  of the borrowed securities that occurs during
the term of the loan inures to  the Portfolio and its respective investors.  The
Portfolio  may pay reasonable  finders' and custodial fees  in connection with a
loan. In addition, the Portfolio will consider all the facts and  circumstances,
including  the creditworthiness of the  borrowing financial institution, and the
Portfolio will not make any loans in excess of one year. The Portfolio will  not
lend  its securities to any officer, Trustee, Director, employee or affiliate or
placement agent of the Company, the Portfolio, or the Adviser, Administrator  or
Distributor, unless otherwise permitted by applicable law.
 
FOREIGN  INVESTMENT INFORMATION. The Portfolio 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 the  Portfolio's  investments  in
foreign  securities may be adversely affected  by changes in political or social
conditions,  diplomatic   relations,   confiscatory   taxation,   expropriation,
nationalization,  limitation on the removal of funds or assets, or imposition of
(or change in) exchange control or  tax regulations in those foreign  countries.
In  addition,  changes in  government  administrations or  economic  or monetary
policies in  the  United  States  or abroad  could  result  in  appreciation  or
depreciation  of portfolio securities and  could favorably or unfavorably affect
the Portfolio's  operations. Furthermore,  the economies  of individual  foreign
nations  may differ  from the U.S.  economy, favorably or  unfavorably, in areas
such  as  growth  of  gross   national  product,  rate  of  inflation,   capital
reinvestment, resource self-sufficiency and balance of payments position; it may
also  be  more difficult  to obtain  and  enforce a  judgment against  a foreign
issuer. Any foreign investments made by the Portfolio must be made in compliance
with U.S. and foreign currency restrictions and tax laws restricting the amounts
and types of foreign investments.
 
In addition,  while  the  volume  of  transactions  effected  on  foreign  stock
exchanges  has increased in  recent years, in most  cases it remains appreciably
below that of domestic security exchanges. Accordingly, the Portfolio's  foreign
investments  may  be less  liquid and  their  prices may  be more  volatile than
comparable investments in securities of U.S. companies. Moreover, the settlement
periods for foreign securities, which are often longer than those for securities
of  U.S.  issuers,  may  affect  portfolio  liquidity.  In  buying  and  selling
securities  on foreign exchanges, purchasers normally pay fixed commissions that
are generally  higher than  the  negotiated commissions  charged in  the  United
States. In addition, there is generally less
 
                                      -9-
 

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

<PAGE>
ILLIQUID  INVESTMENTS; PRIVATELY  PLACED AND OTHER  UNREGISTERED SECURITIES. The
Portfolio may not acquire any illiquid securities if, as a result thereof,  more
than  15% of the market value of the Portfolio's net assets would be in illiquid
investments or investments  that are  not readily marketable.  In addition,  the
Portfolio  will not invest more than 10% of the market value of its total assets
in restricted securities  (not including  Rule 144A securities)  that cannot  be
offered  for public  sale in  the United  States without  first being registered
under the Securities Act of 1933  (the 'Securities Act'). Subject to those  non-
fundamental  policy limitations, the Portfolio  may acquire investments that are
illiquid or have limited  liquidity, such as  private placements or  investments
that  are not  registered under  the Securities Act,  and cannot  be offered for
public sale in  the United States  without first being  registered. An  illiquid
investment is any investment that cannot be disposed of within seven days in the
normal  course of business at approximately the  amount at which it is valued by
the Portfolio.  Repurchase  agreements maturing  in  more than  seven  days  are
considered illiquid investments and, as such, are subject to the limitations set
forth in this paragraph. The price the Portfolio pays for illiquid securities or
receives  upon resale may be  lower than the price  paid or received for similar
securities with  a  more liquid  market.  Accordingly, the  valuation  of  these
securities will reflect any limitations on their liquidity.
 
The  Portfolio  may also  purchase Rule  144A  securities sold  to institutional
investors without registration under the Securities Act. These securities may be
determined to be liquid in accordance with guidelines established by the Adviser
and approved  by the  Trustees of  the Trust.  The Trustees  of the  Trust  will
monitor the Adviser's implementation of these guidelines on a periodic basis.
 
FUTURES  AND OPTIONS TRANSACTIONS. The Portfolio  is permitted to enter into the
futures and options transactions described below. These instruments are commonly
known as derivatives.
 
The Portfolio may purchase and sell exchange traded and over-the-counter ('OTC')
put and  call options  on fixed  income securities  or indices  of fixed  income
securities, enter into forward contracts, purchase and sell futures contracts on
indices  of fixed income securities,  purchase and sell put  and call options on
futures contracts on indices  of fixed income securities  and purchase and  sell
options  on currencies.  The Portfolio may  use these techniques  for hedging or
risk management  purposes or,  subject to  certain limitations,  for  investment
purposes  in  lieu  of investing  directly  in the  corresponding  securities or
instruments. Such use of derivatives may be considered speculative.
 
The Portfolio  may use  these  techniques to  manage  its exposure  to  changing
interest rates, currency exchange rates and/or security prices. Some options and
futures strategies, including selling futures contracts and buying puts, tend to
hedge  the Portfolio's investments against price fluctuations. Other strategies,
including buying futures contracts,  writing puts and  calls, and buying  calls,
may  tend to increase market  exposure. For example, if  the Portfolio wishes to
obtain exposure to a  particular market or  market sector but  does not wish  to
purchase  the  relevant  securities, it  could,  as an  alternative,  purchase a
futures contract on an  index of such securities  or related securities. Such  a
purchase  would not  constitute a  hedging transaction  and could  be considered
speculative. However, the  Portfolio will  use futures contracts  or options  in
this  manner only for the  purpose of obtaining the same  level of exposure to a
particular market or market sector that it could have obtained by purchasing the
relevant securities and will  not use futures contracts  or options to  leverage
its  exposure beyond this level. The use of options and futures may involve some
leverage; such leverage is reduced by the requirement of the SEC to 'cover' such
obligations. See  'Cover  -- Segregated  Accounts'  below. Options  and  futures
contracts  may be combined with each other or with forward contracts in order to
adjust the risk and return  characteristics of the Portfolio's overall  strategy
in  a  manner  deemed  appropriate  to  the  Adviser  and  consistent  with  the
Portfolio's objective and policies. Because combined positions involve  multiple
trades,  they result in  higher transaction costs  and may be  more difficult to
open and close out.
 
The Portfolio's  use of  these transactions  is a  highly specialized  activity,
which  involves investment strategies and  risks different from those associated
with ordinary portfolio securities transactions,  and there can be no  guarantee
that  their use will increase the  Portfolio's return. While the Portfolio's use
of these  instruments  may  reduce  certain risks  associated  with  owning  its
portfolio securities, these techniques themselves entail certain other risks. If
the  Adviser  applies  a strategy  at  an  inappropriate time  or  judges market
conditions or  trends incorrectly,  such strategies  may lower  the  Portfolio's
return. Certain strategies limit the Portfolio's opportunity to realize gains as
well as limiting its exposure to losses. The
 
                                      -11-
 


<PAGE>
Portfolio  could  experience losses  if the  prices of  its options  and futures
positions were poorly correlated with its other investments, or if it could  not
close  out its positions  because of an illiquid  secondary market. In addition,
the  Portfolio  will  incur  costs,  including  commissions  and  premiums,   in
connection  with these  transactions and these  transactions could significantly
increase the Portfolio's turnover rate.
 
The Portfolio  may  purchase  and  sell put  and  call  options  on  securities,
currencies,  indices of securities  and futures contracts,  or purchase and sell
futures contracts for the purposes described herein.
 
The Commodity Exchange Act prohibits U.S. persons, such as the Fund, 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  Portfolio will not  be considered a
'commodity pool'  for purposes  of CFTC  rules, the  Portfolio will  enter  into
transactions  in futures contracts  or options on futures  contracts only if (1)
such transactions constitute  bona fide hedging  transactions, as defined  under
CFTC  rules, or (2) no more than 5%  of the Portfolio's net assets are committed
as initial margin  or premiums  to positions that  do not  constitute bona  fide
hedging transactions.
 
OPTIONS
 
PURCHASING  PUT  AND CALL  OPTIONS. By  purchasing a  put option,  the Portfolio
obtains the right (but not the obligation) to sell the instrument underlying the
option at a fixed strike price. In return for this right, the Portfolio pays the
current market price for the option (known as the option premium). Options  have
various   types  of  underlying   instruments,  including  specific  securities,
currencies, indices  of securities,  indices of  securities prices  and  futures
contracts.  The Portfolio  may terminate  its position  in a  put option  it has
purchased by allowing it  to expire or by  exercising the option. The  Portfolio
may  also  close  out a  put  option  position by  entering  into  an offsetting
transaction, if a liquid market exists. If the option is allowed to expire,  the
Portfolio will lose the entire premium it paid. If the Portfolio exercises a put
option  on a security, it will sell  the instrument underlying the option at the
strike price. If the Portfolio exercises an option on an index, settlement is in
cash and does not involve the actual sale of securities. American style  options
may  be exercised on any day up to their expiration date. European style options
may be exercised only on their expiration date.
 
The buyer of a typical put option can  expect to realize a gain if the price  of
the  underlying instrument  falls substantially.  However, if  the price  of the
instrument underlying the  option does  not fall enough  to offset  the cost  of
purchasing  the option, a put buyer can expect  to suffer a loss (limited to the
amount of the premium paid, plus related transaction costs).
 
The features of call options are essentially  the same as those of put  options,
except that the purchaser of a call option obtains the right to purchase, rather
than  sell, the instrument underlying the option at the option's strike price. A
call buyer typically attempts to participate in potential price increases of the
instrument underlying the option with risk limited to the cost of the option and
related transaction costs if security prices  fall. At the same time, the  buyer
can  expect to  suffer a  loss if  security prices  do not  rise sufficiently to
offset the cost of the option.
 
SELLING (WRITING) PUT AND CALL OPTIONS. When the Portfolio writes a put  option,
it  takes the opposite side  of the transaction from  the option's purchaser. In
return for receipt of the premium,  the Portfolio assumes the obligation to  pay
the  strike price for the instrument underlying the option if the other party to
the option  chooses to  exercise it.  The Portfolio  may seek  to terminate  its
position  in a put option it writes  before exercise by purchasing an offsetting
option in the market at its current price. If the market is not liquid for a put
option the Portfolio  has written, however,  the Portfolio must  continue to  be
prepared  to pay the strike price while the option is outstanding, regardless of
price changes, and must continue to post margin as discussed below.
 
If the price of  the underlying instrument rises,  a put writer would  generally
expect  to  profit, although  its gain  would be  limited to  the amount  of the
premium it received. If security prices remain the same over time, it is  likely
that  the writer will  also profit, because it  should be able  to close out the
option at a lower price. If security prices fall, however, the put writer  would
expect to suffer a loss. This loss should
 
                                      -12-
 


<PAGE>
be  less than  the loss  from purchasing  and holding  the underlying instrument
directly, however, because the  premium received for  writing the option  should
offset a portion of the decline.
 
Writing  a call option obligates  the Portfolio to sell  or deliver the option's
underlying instrument  in return  for  the strike  price  upon exercise  of  the
option.  The characteristics  of writing  call options  are similar  to those of
writing put  options,  except  that  writing calls  generally  is  a  profitable
strategy  if  prices remain  the same  or  fall. Through  receipt of  the option
premium a call writer  offsets part of  the effect of a  price decrease. At  the
same  time, because  a call  writer must be  prepared to  deliver the underlying
instrument in return for the strike price, even if its current value is greater,
a call writer gives up some ability to participate in security price increases.
 
The writer of a U.S. exchange traded put or call option on a security, an  index
of securities or a futures contract is required to deposit cash or securities or
a  letter of credit as  margin and to make  mark-to-market payments of variation
margin if and as the position becomes unprofitable.
 
OPTIONS  ON  INDICES.  The  Portfolio   is  permitted  to  enter  into   options
transactions  and may purchase and  sell put and call  options on any securities
index based  on  securities  in  which the  Portfolio  may  invest.  Options  on
securities  indices  are  similar  to options  on  securities,  except  that the
exercise of securities  index options is  settled by cash  payment and does  not
involve  the actual purchase  or sale of securities.  In addition, these options
are designed to reflect price fluctuations  in a group of securities or  segment
of  the securities market  rather than price fluctuations  in a single security.
The Portfolio, in purchasing  or selling index options,  is subject to the  risk
that  the value of its  portfolio securities may not change  as much as an index
because the Portfolio's investments generally will not match the composition  of
an index.
 
For  a number of reasons,  a liquid market may not  exist and thus the Portfolio
may not be able to close out  an option position that it has previously  entered
into.  When the  Portfolio purchases an  OTC option,  it will be  relying on its
counterparty to perform its obligations, and the Portfolio may incur  additional
losses if the counterparty is unable to perform.
 
FUTURES CONTRACTS
 
When  the  Portfolio  purchases a  futures  contract,  it agrees  to  purchase a
specified quantity of an  underlying instrument at a  specified future date  and
price  or to make or receive  a cash payment based on  the value of a securities
index. When  the  Portfolio  sells a  futures  contract,  it agrees  to  sell  a
specified  quantity of the underlying instrument  at a specified future date and
price or to receive or  make a cash payment based  on the value of a  securities
index.  The price at which  the purchase and sale will  take place is fixed when
the Portfolio enters into the contract. Futures can be held until their delivery
dates or the positions can be (and  normally are) closed out before then.  There
is  no assurance,  however, that  a liquid  market will  exist when  a Portfolio
wishes to close out a particular position.
 
When the  Portfolio purchases  or sells  a futures  contract, the  value of  the
futures  contract tends to increase and decrease in tandem with the value of its
underlying instrument. Purchasing  futures contracts  may tend  to increase  the
Portfolio's  exposure  to  positive  and  negative  price  fluctuations  in  the
underlying instrument, much  as if  it had purchased  the underlying  instrument
directly,  as discussed above.  When the Portfolio sells  a futures contract, by
contrast, the value of  its futures position  will tend to  move in a  direction
contrary to the value of the underlying instrument. Selling futures contracts on
securities  similar  to those  held by  the Portfolio,  therefore, will  tend to
offset both  positive  and  negative  market  price  changes,  much  as  if  the
underlying instrument had been sold. Because there are a limited number of types
of  exchange-traded  options  and futures  contracts,  it is  likely  that these
standardized instruments  will  not exactly  match  the Portfolio's  current  or
anticipated  investments.  The Portfolio  may  invest in  futures  contracts and
options thereon based  on currencies  or on securities  with different  issuers,
maturities,  or other characteristics from the  securities in which it typically
invests, which involves  a risk that  the options or  futures position will  not
track  the performance of  the Portfolio's other  investments. The Portfolio may
also enter into transactions  in futures contracts  and options for  non-hedging
purposes, as discussed above.
 
The  purchaser or seller of a futures contract is not required to deliver or pay
for the underlying  instrument unless the  contract is held  until the  delivery
date.  However, when the Portfolio  buys or sells a  futures contract it will be
required to deposit 'initial margin' with the Custodian in a segregated  account
 
                                      -13-
 


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

Directors  and  officers appears  in the  SAI under  the heading  'Directors and
Trustees'. The Trustees  of the  Trust are also  the Directors  of the  Company,
which  raises certain conflicts of interest. The Company and the Trust have each
adopted written procedures  reasonably designed  to deal  with these  conflicts,
should  they arise. The officers of the  Company are also employees of Signature
or its affiliates.
 
ADVISER AND FUNDS SERVICES AGENT. The  Company has not retained the services  of
an investment adviser with respect to the Fund because the Fund seeks to achieve
its  investment  objective by  investing  all of  its  investable assets  in the
Portfolio. The Portfolio has retained the  services of the Branch as  investment
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.
 
   
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,  1996, the Bank  (including its  consolidated subsidiaries) had
total assets of $326.7 billion and equity capital and reserves of 17.1 billion.
    
 
The Branch provides investment advice and portfolio management to the Portfolio.
Subject to the  supervision of the  Trustees, the Branch  makes the  Portfolio's
day-to-day  investment  decisions,  arranges  for  the  execution  of  portfolio
transactions and generally manages  the Portfolio's investments and  operations.
See 'Investment Adviser' in the SAI.
 
The  Adviser  uses  a  sophisticated,  disciplined,  collaborative  process  for
managing all asset  classes. Louis  N. Cohen  is primarily  responsible for  the
day-to-day  management  and  implementation  of the  Adviser's  process  for the
Portfolio. Mr. Cohen is  also a portfolio manager  of UBS Asset Management  (New
York)  Inc., a position he has held  since March 1991. Previously, Mr. Cohen was
employed by PaineWebber, Inc. as a credit officer from April 1990 through  March
1991.  Mr. Cohen is currently managing several portfolios and is responsible for
all credit research relating  to the issuers in  which these portfolios  invest.
Mr. Cohen has previously managed the investments of an offshore mutual fund. Mr.
Cohen received both a B.A. and M.B.A. from New York University and has seventeen
years  of investment experience. The Branch  has not previously advised a mutual
fund,  but  has  considerable   experience  managing  portfolios  with   similar
investment objectives. This may be viewed as a risk of investing in this Fund.
 
In  addition to the  above-listed investment advisory  services, the Branch also
provides  the  Fund  and  the  Portfolio  with  certain  related  administrative
services.   Subject  to   the  supervision   of  the   Directors  and  Trustees,
respectively, the Branch is responsible for: establishing performance  standards
for  the third-party service providers of  the Fund and Portfolio and overseeing
and evaluating  the  performance  of such  entities;  providing  and  presenting
quarterly  management reports to the Directors and the Trustees; supervising the
preparation of reports  for Fund  and Portfolio  shareholders; and  establishing
voluntary  expense limitations for the Fund  and providing any resultant expense
reimbursement to the Fund.
 
The Branch provides its administrative services to the Fund pursuant to a  Funds
Services  Agreement  between the  Branch and  the Company.  The Branch  does not
receive a fee from the  Company or the Fund pursuant  to the terms of the  Funds
Services Agreement.
 
Under  the Trust's Investment Advisory Agreement, the Portfolio pays the Adviser
a fee, calculated daily and payable monthly, equal, on an annual basis, to 0.45%
of the Portfolio's average daily net  assets. The Branch has voluntarily  agreed
to  waive its  fees and reimburse  the Fund for  any of its  direct and indirect
expenses to the extent that the  Fund's total operating expenses (including  its
share  of the  Portfolio's expenses)  exceed, on an  annual basis,  0.80% of the
Fund's average daily net assets. The  Branch may modify or discontinue this  fee
waiver  and expense  limitation at any  time in  the future with  30 days' prior
notice to the Fund. See 'Expenses'.

ADMINISTRATORS. Under Administrative Service Agreements with the Company and the
Trust,  Signature and Signature-Cayman  serve as the  Administrators of the Fund
and the Portfolio, respectively (in  such capacities, the 'Administrators').  In
these  capacities, Signature and Signature-Cayman  administer all aspects of the
Fund's and the Portfolio's day-to-day operations, subject to the supervision  of
the  Adviser, and the Directors and Trustees, as applicable, except as set forth

See  'Custodian' in  the SAI.  The Custodian also  maintains offices  at 1 First
Canadian Place, Suite 2800, Toronto, Ontario M5X1C8.
 
SHAREHOLDER SERVICES
 
The Company has entered into a shareholder servicing agreement with the  Branch,
and  may enter into additional shareholder servicing agreements with one or more
financial institutions (together with the Branch, 'Eligible Institutions')  such
as   a  federal  or  state-chartered  bank,  trust  company,  savings  and  loan
association or  savings bank,  or broker-dealer.  Pursuant to  each  shareholder
servicing agreement, an Eligible Institution, as agent for its customers who are
purchasing  shares of  the Fund, will  perform the following  services for these
investors, among other  things: coordinating shareholder  accounts and  records,
assisting  investors  seeking  to  purchase  or  redeem  Fund  shares, providing
performance information  relating to  the Fund,  and responding  to  shareholder
inquiries.  The Company has  agreed to pay  each Eligible Institution  a fee for
these services equal,  on an annual  basis, to  0.25% of the  average daily  net
assets of the Fund represented by shares of the Fund owned during the period for
which  payment is being made by customers of the Eligible Institution. Under the
terms  of  the  shareholder  servicing  agreements,  Eligible  Institutions  may
delegate  one  or more  of  their responsibilities  to  other entities  at their
expense.
 
EXPENSES
 
   
In addition  to  the  fees  of  the  Branch,  Signature-Cayman,  Signature,  and
Investors Bank & Trust Company, the Fund will be responsible for other expenses,
including  brokerage costs and litigation and extraordinary expenses. The Branch
has voluntarily  agreed to  limit  the total  operating  expenses of  the  Fund,
excluding  extraordinary  expenses, to  an annual  rate of  0.80% of  the Fund's
average daily net assets.  The Branch may modify  or discontinue this  voluntary
expense  limitation at any time in the future  with 30 days' prior notice to the
Fund.

The Fund  and  the  Portfolio  may  allocate  brokerage  transactions  to  their
affiliates and the Adviser's affiliates only if the commissions received by such
affiliates  are fair  and reasonable  when compared  to the  commissions paid to
unaffiliated brokers in connection with comparable transactions. See  'Portfolio
Transactions' in the SAI.
 
PURCHASE OF SHARES
 
GENERAL  INFORMATION  ON  PURCHASES.  Investors may  purchase  Fund  shares only
through  the  Distributor.  All  purchase   orders  must  be  accepted  by   the
Distributor.  The  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 Fund may be purchased only in those states where
they may be lawfully sold.
 
The business days of the Fund and the Portfolio are the days the New York  Stock
Exchange (the 'NYSE') is open for regular trading.
 
The  shares of the Fund are sold on a continuous basis without a sales charge at
the net asset value per share next determined after receipt and acceptance of  a
purchase  order by the Distributor.  The Fund calculates its  net asset value at
the close of business. See 'Net Asset Value'. The minimum initial investment  in
the  Fund is $25,000, except that the  minimum initial investment is $10,000 for
shareholders of another series of the Company. The minimum subsequent investment
in the Fund  for all  investors is $5,000.  The minimum  initial investment  for
employees  of  the Bank  or  its affiliates  is  $5,000. The  minimum subsequent
investment is $1,000. For purposes  of the minimum investment requirements,  the
Fund may aggregate investments by related shareholders. These minimum investment
requirements  may be waived at the Fund's discretion. 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  investor's  subscription  is  accepted.  See
'Purchase of Shares' in the SAI.
 
Purchase  orders in proper form  received by the Distributor  prior to 4:00 p.m.
New York time or the close of regular trading on the NYSE, whichever is earlier,
are effective and  executed at  the net asset  value next  determined that  day.
Purchase orders received after 4:00 p.m. New York time or the close of the NYSE,
whichever  is earlier, will be executed at the net asset value determined on the
next business day. Investors become record shareholders of the Fund on the  next
business day ('day two') after they place their subscription order, provided the
Custodian  receives payment for  the shares on day  two. As record shareholders,
investors are entitled to earn dividends.  Settlement date for purchases is  the
next business day following trade date.
 
Customers  of  Eligible Institutions  should request  a representative  of their
Eligible Institution  to  assist them  in  placing  a purchase  order  with  the
Distributor.
 
Shareholders  who  do not  currently maintain  a  relationship with  an Eligible
Institution may purchase  shares of the  Fund directly from  the Distributor  by
wire transfer or mail.
 
The  Transfer Agent will maintain the accounts for all shareholders who purchase
Fund shares directly  through the Distributor.  For account balance  information
and shareholder services, such shareholders should contact the Transfer Agent at
(888)  UBS-FUND or in writing at UBS Private Investor Funds, Inc., c/o Investors
Bank & Trust Company, P.O. Box 1537 MFD 23, Boston, MA 02205-1537.
 
By wire: Purchases may be made by federal funds wire. To place a purchase  order
with  the  Fund, the  shareholder  must telephone  the  Transfer Agent  at (888)
UBS-FUND for specific instructions.
 
Subject to the minimum purchase  requirements discussed above, shares  purchased
by  federal funds wire  will be effected at  the net asset  value per share next
determined after acceptance of the order.
 
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  shareholder's account  number
must be clearly marked on the check to ensure proper credit.
 
By   mail:  Subject  to  the  minimum  purchase  requirements  discussed  above,
shareholders may  purchase  shares  of  the  Fund  through  the  Distributor  by
completing an account application and mailing it, together
 
                                      -17-

with  a check  payable to  'UBS Private  Investor Funds,  Inc.', to  UBS Private
Investor Funds, Inc., c/o Investors Bank & Trust Company, P.O. Box 1537 MFD  23,
Boston, MA 02205-1537.
 
Checks  are subject to collection at full  value. For shares purchased by check,
dividend payments and redemption  proceeds, if any, will  be delayed until  such
funds are collected, which may take up to 15 days from the date of purchase.
 
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. The Fund calculates its net  asset value at the close of  business.
See 'Net Asset Value'.
 
A  redemption order will  be effected provided the  Distributor receives such an
order prior to 4:00 p.m.  New York time or the  close of regular trading on  the
NYSE,  whichever is earlier. The  redemption of Fund shares  is effective and is
executed at the  net asset  value next  determined that  day. Redemption  orders
received  after 4:00 p.m. New  York time or the close  of regular trading on the
NYSE, whichever is earlier, will be  executed at the net asset value  determined
on  the next  business day.  Proceeds of  an effective  redemption are generally
deposited the next business  day in immediately available  funds to the  account
designated  by the redeeming shareholder or  mailed to the shareholder's address
of record, in accordance with the shareholder's instructions.
 
Shareholders will continue to earn dividends through the day of redemption.
 
Customers of  Eligible  Institutions  must request  a  representative  of  their
Eligible  Institution to assist them in placing a redemption order. Shareholders
whose accounts are maintained  by the Transfer Agent  may redeem Fund shares  by
telephone or mail.
 
By telephone: Telephone redemptions may be made by calling the Transfer Agent at
(888) UBS-FUND. Redemption orders will be accepted until 4:00 p.m. New York time
or  the close of  regular trading on  the NYSE, whichever  is earlier. Telephone
redemption requests  are  limited  to those  shareholders  who  have  previously
elected  this service.  Such shareholders  risk possible  loss of  principal and
income in the event of a telephone  redemption not authorized by them. The  Fund
and  the  Transfer  Agent  will  employ  reasonable  procedures  to  verify that
telephone redemption instructions are genuine and will require that shareholders
electing such an option provide a  form of personal identification. The  failure
by  the Fund or the Transfer Agent to  employ such procedures may cause the Fund
or the Transfer Agent to be liable  for any losses incurred by investors due  to
telephone  redemptions based  upon unauthorized or  fraudulent instructions. The
telephone redemption option may be modified or discontinued at any time upon  60
days' notice to shareholders.
 
By  mail:  Redemption  requests  may  also  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, 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.
The redemption request  in proper form  should be sent  to UBS Private  Investor
Funds,  Inc., c/o Investors Bank & Trust  Company, P.O. Box 1537 MFD 23, Boston,
MA 02205-01537.
 
                                      -18-



<PAGE>
MANDATORY REDEMPTION. If the value of a shareholder's holdings in the Fund falls
below  $10,000 because  of a redemption  of shares,  the shareholder's remaining
shares may  be redeemed  60 days  after  written notice  unless the  account  is
increased  to $10,000 or more. For example, a shareholder whose initial and only
investment is $10,000 may be subject to mandatory redemption resulting from  any
redemption that causes his or her investment to fall below $10,000.
 
FURTHER  REDEMPTION INFORMATION. Investors should  be aware that redemptions may
not be processed unless the redemption  request is submitted in proper form.  To
be  in  proper form,  the  Fund must  have  received the  shareholder's taxpayer
identification number and address.  As discussed under  'Taxes' below, the  Fund
may  be  required  to impose  'back-up'  withholding  of federal  income  tax on
dividends, distributions and redemptions  when non-corporate investors have  not
provided a certified taxpayer identification number. In addition, if an investor
sends  a check to the Distributor for the purchase of Fund shares and shares are
purchased with funds  made available  by the  Distributor before  the check  has
cleared,  the transmittal of  redemption proceeds from the  sale of those shares
will not occur until the check used  to purchase such shares has cleared,  which
may take up to 15 days. Redemption delays may be avoided by purchasing shares by
federal funds wire.
 
The  right of redemption may  be suspended or the  date of payment postponed for
such periods as the 1940 Act or  the SEC may permit. See 'Redemption of  Shares'
in the SAI.
 
EXCHANGE OF SHARES
 
An  investor may  exchange Fund  shares for  shares of  any other  series of the
Company without charge. An exchange  may be made so  long as after the  exchange
the  investor has shares, in each series in which it remains an investor, with a
value equal to or greater than each such series' minimum investment amount.  See
'Purchase  of Shares' in  the prospectuses of  the other Company  series for the
minimum investment amounts for each of those funds. Shares are exchanged on  the
basis of relative net asset value per share. Exchanges are in effect redemptions
from  one  fund  and  purchases  of another  fund  and  the  usual  purchase and
redemption  procedures  and  requirements  are  applicable  to  exchanges.   See
appropriate  section relating to  the purchase and redemption  of shares in this
and  other  prospectuses.  See  also  'Additional  Information'  below  for   an
explanation of the telephone exchange policy.
 
Shareholders  subject to federal income tax who  exchange shares in one fund for
shares in another fund may recognize capital gain or loss for federal income tax
purposes. The  Fund  reserves the  right  to  discontinue, alter  or  limit  its
exchange  privilege  at  any  time.  For  investors  in  certain  states,  state
securities laws may restrict the availability of the exchange privilege.
 
RETIREMENT PLANS
 
The Fund  has available  a form  of Individual  Retirement Account  ('IRA')  for
investment in Fund shares. Subject to certain restrictions imposed by applicable
tax  laws, self-employed  individuals may  purchase shares  of the  Fund through
tax-deductible contributions to existing retirement plans known as Self-Employed
Retirement Plans ('SERPs'). Fund  shares may also be  a suitable investment  for
'401(k) Plans' which subject to certain restrictions allow their participants to
invest  in qualified pension  plans on a  tax-deferred basis. The  Fund does not
currently act as sponsor to such plans.
 
The minimum initial  investment for  all such  retirement plans  is $2,000.  The
minimum for all subsequent investments is $500.
 
Under the 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 $2,250 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
 
                                      -19-
 


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

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,  three
series have been authorized, of which UBS Bond Portfolio is one.
 
The  Declaration  of  Trust  provides  that  no  Trustee,  shareholder, officer,
employee, or agent of  the Trust shall  be held to  any personal liability,  nor
shall  resort be had to  such person's private property  for the satisfaction of
any obligation  or claim  or otherwise  in connection  with the  affairs of  the
Portfolio, but that only the Trust property shall be liable.
 
The  Declaration of Trust provides that the Fund and other entities investing in
the Portfolio  (e.g., other  investment  companies, insurance  company  separate
accounts  and common and commingled trust funds) will each be liable for all the
obligations of  the  Portfolio.  However,  the  risk  of  the  Fund's  incurring
financial loss on account of such liability is limited to circumstances in which
both  inadequate insurance existed  and the Portfolio itself  was unable to meet
its obligations. Accordingly, the Trustees believe that neither the Fund nor its
shareholders will be adversely  affected by reason of  the Fund's investment  in
the Portfolio.
 
TAXES
 
Each  Fund  has  qualified  and  intends  to  remain  qualified  as  a regulated
investment company (a 'RIC') under  Subchapter M of the Code.  As a RIC, a  Fund
(as  opposed to its shareholders) will not be subject to federal income taxes on
the net  investment  income  and  capital  gains  that  it  distributes  to  its
shareholders,  provided  that at  least  90% of  its  net investment  income and
realized net short-term capital gains in excess of net long-term capital  losses
for  the taxable  year is  distributed. The  Portfolio intends  to qualify  as a
partnership for federal income  tax purposes. As  such, the Portfolio  generally
should  not be subject to tax. The status  of the Fund as a regulated investment
company  is  dependent  on,  among  other  things,  the  Portfolio's   continued
qualification as a partnership for federal income tax purposes.
 
Distributions of net long-term capital gains in excess of net short-term capital
losses are taxable to Fund shareholders as long-term capital gains regardless of
how  long a shareholder  has held shares  in the Fund  and regardless of whether
received in the form of cash  or reinvested in additional shares.  Distributions
of  net investment income and realized net short-term capital gains in excess of
net  long-term  capital  losses   are  taxable  as   ordinary  income  to   Fund
shareholders,  whether such  distributions are received  in the form  of cash or
reinvested in additional shares. Annual statements as to the current federal tax
status of distributions  will be  mailed to shareholders  after the  end of  the
taxable  year for the Fund. Distributions  to corporate shareholders of the Fund
will not qualify for the dividends-received deduction because the income of  the
Fund will not consist of dividends paid by United States corporations.
 
Any  gain or  loss realized on  the redemption or  exchange of Fund  shares by a
shareholder who  is not  a dealer  in securities  generally will  be treated  as
long-term  capital gain or loss  if the shares have been  held for more than one
year, and  otherwise as  short-term  capital gain  or  loss. However,  any  loss
realized  by a shareholder upon the redemption or exchange of shares in the Fund
held for six months or less will be  treated as a long-term capital loss to  the
extent  of any long-term capital gain  distributions received by the shareholder
with respect to such shares. In addition, no loss will be allowed on the sale or
other disposition of shares  of the Fund  if, and to the  extent that, within  a
period  beginning 30 days before the date of such sale or disposition and ending
30 days  after  such  date,  the  holder  acquires  (such  as  through  dividend
reinvestment)  securities that are substantially identical  to the shares of the
Fund.
 
The Fund will generally be subject to an  excise tax of 4% on the amount of  any
income  or  capital  gains,  above  certain  permitted  levels,  distributed  to
shareholders on  a  basis such  that  such income  or  gain is  not  taxable  to
shareholders  in  the  calendar  year  in  which  it  was  earned  by  the Fund.
Furthermore, dividends declared  in October,  November, or  December payable  to
shareholders  of record  on a  specified date in  such a  month and  paid in the
following January will be treated as having  been paid by the Fund and  received
 
                                      -21-
 


<PAGE>
by each shareholder in December. Under this rule, therefore, shareholders may be
taxed  in one year on dividends or distributions actually received in January of
the following year.
 
Distributions of net long-term  capital gains will have  the effect of  reducing
the  net asset value of the Fund's shares  by the amount of the distribution. If
the net asset value is reduced below a shareholder's cost, the distribution will
nonetheless be taxable as described above, even if the distribution represents a
return of invested capital.  Investors should consider  the tax implications  of
buying shares just prior to a distribution, when the price of shares may reflect
the amount of the forthcoming distribution.
 
If  a correct and certified  taxpayer identification number is  not on file, the
Fund is required,  subject to  certain exemptions,  to withhold  31% of  certain
payments   made  or   distributions  declared   to  non-corporate  shareholders.
Shareholders should be aware that, under applicable regulations, the Fund may be
fined up  to  $50 annually  for  each account  for  which a  certified  taxpayer
identification  number is not provided. In the event that such a fine is imposed
with respect to any uncertified account in any year, a corresponding charge  may
be made against that account.
 
This  discussion of tax consequences is based on U.S. federal tax laws in effect
on the date of this Prospectus. These laws and regulations are subject to change
by legislative  or  administrative  action, possibly  with  retroactive  effect.
Investors  are urged to consult their own  tax advisors with respect to specific
questions as to federal taxes and with respect to the applicability of state  or
local taxes. See 'Taxes' in the SAI.
 
ADDITIONAL INFORMATION
 
The  Fund  will  send  its  shareholders  annual  and  semi-annual  reports. The
financial statements appearing in annual reports will be audited by  independent
accountants.  Shareholders also will be sent  confirmations of each purchase and
redemption and periodic  statements reflecting all  account activity,  including
dividends  and any distributions whether reinvested in additional shares or paid
in cash.
 
Shareholders of  certain Eligible  Institutions may  be given  the privilege  to
initiate  transactions  automatically  by  telephone  upon  opening  an account.
However, an investor should be aware that a transaction authorized by  telephone
and  reasonably believed to be genuine by  the Company, the Branch, the Eligible
Institution, the Transfer Agent or the  Distributor may subject the investor  to
risk  of loss if such  instruction is subsequently found  not to be genuine. The
Company and its service providers  will employ reasonable procedures,  including
requiring investors to give a form of personal identification and tape recording
of telephonic instructions, to confirm that telephonic instructions by investors
are  genuine; if it does not,  it or the service provider  may be liable for any
losses due to unauthorized or fraudulent instructions.
 
The Fund may make historical  performance information available and may  compare
its  performance to other  investments or relevant  indices, including data from
Lipper Analytical Services, Inc., Lehman Government/Corporate Intermediate  Bond
Index,  Micropal Inc., Morningstar Inc.,  Ibbotson Associates, Standard & Poor's
500 Composite  Stock Price  Index,  the Dow  Jones  Average, the  Frank  Russell
Indices,  the  EAFE  Index, the  Financial  Times  World Stock  Index  and other
industry publications.
 
The Fund may advertise 'yield'. Yield refers  to the net income generated by  an
investment  in  the  Fund over  a  stated  30-day period.  This  income  is then
annualized -- i.e., the amount of income generated by the investment during  the
30-day  period is assumed to be generated  each 30-day period for 12 periods and
is shown as a percentage of the investment. The income earned on the  investment
is also assumed to be reinvested at the end of the sixth 30-day period.
 
The  Fund may  also advertise  'total return'.  The total  return shows  what an
investment in the Fund would have earned  over a specified period of time  (one,
five  or ten years or  since commencement of operations,  if less) assuming that
all Fund distributions and dividends  were reinvested on the reinvestment  dates
and  less all recurring  fees during the  period and assuming  the redemption of
such investment at the end of each period.
 
These methods of calculating yield and total return are required by  regulations
of  the SEC. Yield and total  return data similarly calculated, unless otherwise
indicated,  over  other  specified  periods  of  time  may  also  be  used.  All
performance  figures are  based on historical  earnings and are  not intended to
indicate future performance. Performance information may be obtained by  clients
of  an Eligible  Institution by  calling the  Eligible Institution,  while other
shareholders may address their inquiries to the Transfer Agent.

PROSPECTUS
 
UBS U.S. EQUITY FUND
6 ST. JAMES AVENUE
BOSTON, MASSACHUSETTS 02116
FOR INFORMATION CALL (800) 914-8566
 
UBS   U.S.  Equity  Fund  (the  'Fund')   seeks  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. It is the  intention of the Adviser  (defined below) that the  average
dividend  yield of the  common stocks held by  the Fund be  at least 50% greater
than 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. There is no
assurance that the Fund will achieve its stated objective.
 
The Fund is  a diversified, no-load  mutual fund  for which there  are no  sales
charges or exchange or redemption fees. The Fund is one of several series of UBS
Private  Investor Funds, Inc. (the 'Company'), an open-end management investment
company organized as a corporation under Maryland law.
 
UNLIKE OTHER MUTUAL FUNDS THAT DIRECTLY  ACQUIRE AND MANAGE THEIR OWN  PORTFOLIO
OF  SECURITIES, THE FUND SEEKS TO  ACHIEVE ITS INVESTMENT OBJECTIVE BY INVESTING
ALL OF ITS INVESTABLE ASSETS IN UBS U.S. EQUITY PORTFOLIO (THE 'PORTFOLIO'). THE
PORTFOLIO IS  A SERIES  OF  UBS INVESTOR  PORTFOLIOS  TRUST, (THE  'TRUST'),  AN
OPEN-END  MANAGEMENT INVESTMENT COMPANY.  THE PORTFOLIO HAS  THE SAME INVESTMENT
OBJECTIVE AS THE FUND. THE FUND EMPLOYS A TWO-TIER MASTER-FEEDER INVESTMENT FUND
STRUCTURE  THAT   IS  MORE   FULLY  DESCRIBED   UNDER  THE   SECTION   CAPTIONED
'MASTER-FEEDER STRUCTURE'.
 
The  Portfolio is advised by the New York Branch (the 'Branch' or the 'Adviser')
of Union Bank of Switzerland (the 'Bank').
 
   
This Prospectus  sets forth  concisely the  information about  the Fund  that  a
prospective  investor  ought to  know before  investing. It  should be  read and
retained for  future reference.  A Statement  of Additional  Information,  dated
March  13,  1997  (the 'SAI'),  provides  further discussion  of  certain topics
referred to in  this Prospectus and  other matters  that may be  of interest  to
investors.  The SAI has been filed  with the Securities and Exchange Commission,
is incorporated  herein  by reference,  and  is available  without  charge  upon
written  request  from the  Company or  Distributor (as  defined herein)  at the
addresses set forth on  the back cover  of the Prospectus,  or by calling  (800)
914-8566.
    
 
INVESTMENTS  IN THE FUND ARE NOT DEPOSITS  WITH OR OBLIGATIONS OF, OR GUARANTEED
OR ENDORSED BY, UNION BANK OF SWITZERLAND OR ANY OTHER BANK. SHARES OF THE  FUND
ARE  NOT  INSURED  BY THE  FEDERAL  DEPOSIT INSURANCE  CORPORATION,  THE FEDERAL

ORIGINALLY INVESTED BY THE INVESTOR.
 
THESE  SECURITIES HAVE  NOT BEEN APPROVED  OR DISAPPROVED BY  THE SECURITIES AND
EXCHANGE COMMISSION OR ANY  STATE SECURITIES COMMISSION  NOR HAS THE  SECURITIES
AND  EXCHANGE  COMMISSION OR  ANY STATE  SECURITIES  COMMISSION PASSED  UPON THE

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

*    Expenses are  expressed as  a percentage of  the Fund's  average daily  net
assets  and are based on  the expenses incurred during  the period April 2, 1996
(commencement of operations) through December 31, 1996, after any applicable fee
waivers and  expense  reimbursements.  Without  such  fee  waivers  and  expense
reimbursements,  Total Operating Expenses would be equal, on an annual basis, to
3.55% of the Fund's average daily net assets. See 'Management'.
    
 
**   The New  York Branch  (the  'Branch' or  the 'Adviser')  of Union  Bank  of
Switzerland (the 'Bank') has agreed to waive fees and reimburse each of the Fund
and  the Portfolio for any of their  respective operating expenses to the extent
that the Fund's total operating expenses (including its share of the Portfolio's
expenses) exceed, on  an annual  basis, 0.90% of  the Fund's  average daily  net
assets. The Branch may modify or discontinue this undertaking at any time in the
future  with 30  days' prior  notice to the  Fund. The  Portfolio's advisory fee
would be equal, on an annual basis, to 0.60% of the average daily net assets  of
the  Portfolio if there were no fee waiver in effect. See 'Management -- Adviser
and Funds Services Agent' and 'Expenses'.
 
*** The fees and  expenses in Other Expenses  include fees payable to  Signature
Broker-Dealer  Services,  Inc.  ('Signature') under  an  Administrative Services
Agreement with  the  Fund, fees  payable  to Signature  Financial  Group  (Grand
Cayman)  Ltd.  ('Signature-Cayman') under  an Administrative  Services Agreement
with the  Portfolio,  fees  payable  to Investors  Bank  &  Trust  Company  (the
'Custodian'  or the 'Transfer Agent') as custodian of the Fund and the Portfolio
and transfer  agent of  the  Fund, and  fees payable  by  the Fund  to  Eligible
Institutions  providing shareholder services under various shareholder servicing
agreements. For a  more detailed  description of  contractual fee  arrangements,
including  fee waivers and expense reimbursements,  and of the fees and expenses
included in Other Expenses, see 'Management' and 'Shareholder Services'.

The  above Expense  Table is designed  to assist investors  in understanding the
various direct and indirect costs and expenses that Fund investors are  expected
to  bear and  reflects the  expenses of  the Fund  and the  Fund's share  of the
Portfolio's expenses. In  connection with  the above Example,  please note  that
$1,000 is less than the Fund's minimum investment requirement and that there are
no  redemption or exchange fees of any kind. See 'Purchase of Shares', 'Exchange
of Shares'  and 'Redemption  of  Shares'. THE  EXAMPLE  IS HYPOTHETICAL;  IT  IS

HISTORICAL PERFORMANCE OF COMPARABLE DISCRETIONARY ACCOUNTS. The following table
sets  forth (i)  the composite  total return  for the  period December  31, 1996
(commencement date) through December  31, 1996 and the  year ended December  31,
1996  for all discretionary accounts described  below that have been managed for
at  least  one  full  quarter  by  UBS  Asset  Management  (New  York)  Inc.,  a
wholly-owned  subsidiary of the Bank ('UBSAM NY'), (ii) the average annual total
return for the Fund  for the period April  2, 1996 (commencement of  operations)
through  June 30, 1996, and  (iii) the annual total  return during the same year
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 Portfolio.  While the  Portfolio will  be
managed by the Branch, the management of the Portfolio will be substantially the
same  as by UBSAM  NY and will be  carried out by  personnel who performed these
services for the discretionary accounts at UBSAM NY, who will be employed by the
Branch for this purpose. The composite  total return for such accounts has  been
adjusted to deduct all of the Fund's annual total operating expenses of 0.90% of
average  daily net assets as set forth in  the Fee Table above. No such accounts
were managed by UBSAM NY or the Branch 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 Portfolio
that, if applied to the accounts, may have adversely affected their  performance
results.  The composite  total return of  these discretionary  accounts does not
represent the historical performance of the  Portfolio and should not be  viewed
as  a prediction of future performance of  the Portfolio. The S&P 500 Index (the
'Index') is an unmanaged  index that includes  500 U.S. stocks  and is a  common

MASTER-FEEDER STRUCTURE
 
Unlike other mutual funds that directly  acquire and manage their own  portfolio
of  securities, the Fund seeks to  achieve its investment objective by investing
all of its  investable assets in  the Portfolio, a  separate investment  company
with  the same investment objective as the Fund. The investment objective of the
Fund and the Portfolio may be changed only with the approval of the holders of a
majority of the outstanding voting securities of  the Fund or a majority of  the
investors in the Portfolio, respectively, after 30 days' prior notice.
 
This   master-feeder  structure  has  been  developed  relatively  recently,  so
shareholders should carefully consider this investment approach.
 
In addition to selling an interest in  the Portfolio to the Fund, the  Portfolio
may  sell  interests in  the Portfolio  to other  mutual funds  or institutional
investors. Such investors  will invest in  the Portfolio on  the same terms  and
conditions  as the Fund  and will pay  a proportionate share  of the Portfolio's
expenses. However, other entities investing in the Portfolio may sell shares  of
their  own  fund  using a  different  pricing  structure than  the  Fund's. Such
different pricing structures may result in differences in returns experienced by
investors in  other funds  that invest  in the  Portfolio. Such  differences  in
returns  are  not uncommon  and  are present  in  other mutual  fund structures.
Information concerning other holders of interests in the Portfolio is  available
from Signature at (617) 423-0800.
 
The  Fund may withdraw its investment in the  Portfolio at any time if the Board
determines that  it is  in the  Fund's best  interest to  do so.  Upon any  such
withdrawal,  the Board would consider what  action might be taken, including the
investment of all the Fund's assets  in another pooled investment entity  having
the  same investment objective and restrictions as  the Fund or the retaining of
an investment  adviser  to manage  the  Fund's  assets in  accordance  with  the
investment policies described below with respect to the Portfolio.
 
Certain   changes  in   the  Portfolio's   investment  objective,   policies  or
restrictions, or a failure by the Fund's shareholders to approve a change in the
Portfolio's investment  objective  or  restrictions, may  require  the  Fund  to
withdraw  its investments in the Portfolio.  Any such withdrawal could result in
an  in-kind  distribution  of  portfolio  securities  (as  opposed  to  a   cash
distribution)  by  the  Portfolio  to  the  Fund.  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 the Fund's having a
less  diversified  portfolio  of  investments  or  adversely  affect  the Fund's
liquidity, and  the  Fund  could  incur  brokerage,  tax  or  other  charges  in
converting  such securities to cash. Notwithstanding  the above, there are other
means for meeting shareholder redemption requests, such as borrowing.
 
Smaller funds  investing in  the Portfolio  may be  materially affected  by  the
actions of larger funds investing in the Portfolio. For example, if a large fund
withdraws  from the Portfolio,  the remaining funds  may subsequently experience
higher pro  rata operating  expenses,  thereby lowering  returns.  Additionally,
because  the Portfolio  would become  smaller, it  may become  less diversified,
resulting in potentially increased portfolio risk (however, these  possibilities
also  exist for traditionally structured funds  that have large or institutional
investors who may withdraw  from a fund).  Also, funds with  a greater pro  rata
ownership   in  the  Portfolio  could  have  effective  voting  control  of  its
operations. Except as permitted by  the Securities and Exchange Commission  (the
'SEC'),    whenever    the   Fund    is   requested    to   vote    on   matters
 
                                      -5-
 


<PAGE>
pertaining  to  the  Portfolio,  the  Company  will  hold  a  meeting  of   Fund
shareholders and will cast all of its votes proportionately as instructed by the
Fund's shareholders. See 'Organization' in the SAI. Fund shareholders who do not
vote  will not affect the Fund's votes  at the Portfolio meeting. The percentage
of the Company's votes representing Fund  shareholders not voting will be  voted
by  the Company in the same proportion as the Fund shareholders who do, in fact,
vote.
 
For more information  about the Portfolio's  investment objective, policies  and
restrictions,  see 'Investment  Objective and  Policies', 'Additional Investment
Information  and  Risk   Factors'  and  'Investment   Restrictions'.  For   more
information about the Portfolio's management and expenses, see 'Management'. For
more   information  about  changing  the   investment  objective,  policies  and
restrictions of the Fund or the Portfolio, see 'Investment Restrictions'.
 
INVESTMENT OBJECTIVE AND POLICIES
 
The investment  objective of  the Fund  and the  Portfolio is  described  below,
together  with  the policies  each  employs to  seek  to achieve  its objective.
Additional information  about  the  investment  policies of  the  Fund  and  the
Portfolio  appears in  the SAI under  'Investment Objectives  and Policies'. The
Fund seeks  to  achieve  its  investment  objective  by  investing  all  of  its
investable  assets in the Portfolio, which  has the same investment objective as
the Fund. There can be no assurance that the investment objective of the Fund or
the Portfolio will be achieved.
 
The 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 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 Portfolio that the Portfolio's  investments have less price volatility  than
the S&P 500 Index.
 
Under normal circumstances, the 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 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 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 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 proved  to be an important component of  total
return.  For  example,  during  the  ten-year  period  ended  December  31, 1996
reinvested 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 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,
 
                                      -6-



<PAGE>
bank certificates of deposit and bankers' acceptances; and repurchase agreements
collateralized  by these securities. The Portfolio may also purchase nonpublicly
offered  debt  securities.  See  'Additional  Investment  Information  and  Risk
Factors  --  Illiquid  Investments;  Privately  Placed  and  Other  Unregistered
Securities'.
 
The Portfolio may also utilize equity futures contracts and options to a limited
extent. Specifically, the Portfolio may enter into futures contracts and options
provided that  such positions  are established  for hedging  purposes only.  See
'Futures Contracts'.
 
The  Portfolio  intends to  manage  its securities  actively  in pursuit  of its
investment objective. Although it generally  seeks to invest for the  long-term,
the Portfolio retains the right to sell securities irrespective of how long they
have  been held.  It is  anticipated that the  annual portfolio  turnover of the
Portfolio will  not  exceed  100%.  To  the  extent  the  Portfolio  engages  in
short-term trading, it may incur increased transaction costs.
 
EQUITY INVESTMENTS. Under normal circumstances, the Adviser intends to invest at
least  80%  of  the 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  Portfolio's  primary equity  investments  are  the
common  stocks of established domestic companies.  The common stock in which the
Portfolio may invest includes  the common stock  of any class  or series or  any
similar  equity interest  such as  trust or  limited partnership  interests. See
'Additional Investment Information and Risk  Factors'. The 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'.
 
ADDITIONAL INVESTMENT INFORMATION AND RISK FACTORS
 
CONVERTIBLE SECURITIES. The  convertible securities in  which the Portfolio  may
invest  include any  debt securities or  preferred stocks that  may be converted
into common stock or that carry the right to purchase common stock.  Convertible
securities  entitle the holder to exchange the securities for a specified number
of shares of  common stock,  usually of the  same company,  at specified  prices
within a certain period of time.
 
WHEN-ISSUED   AND  DELAYED  DELIVERY  SECURITIES.  The  Portfolio  may  purchase
securities on a when-issued or delayed  delivery basis. Delivery of and  payment
for  these securities may take as long as a  month or more after the date of the
purchase commitment.  The  value  of  these  securities  is  subject  to  market
fluctuation  during  this  period  and  no interest  or  income  accrues  to the
Portfolio until settlement. At  the time of  settlement, a when-issued  security
may  be valued at less than its purchase price. Between the trade and settlement
dates, the  Portfolio will  maintain  a segregated  account with  the  Custodian
consisting  of a portfolio of high grade, liquid debt securities with a value at
least equal to these  commitments. When entering into  a when-issued or  delayed
delivery  transaction, the Portfolio will rely  on the other party to consummate
the transaction;  if the  other  party fails  to do  so,  the Portfolio  may  be
disadvantaged.  It is  the current  policy of  the Portfolio  not to  enter into
when-issued commitments exceeding in  the aggregate 15% of  the market value  of
the Portfolio's total assets less liabilities (excluding the obligations created
by these commitments).
 
REPURCHASE   AGREEMENTS.  The  Portfolio  may  engage  in  repurchase  agreement
transactions with  brokers, dealers  or banks  that meet  the credit  guidelines
approved  by the  Trust's Board  of Trustees  (the 'Trustees').  In a repurchase
agreement, the  Portfolio buys  a security  from  a seller  that has  agreed  to
repurchase  it at a mutually agreed upon date and price, reflecting the interest
rate effective for the term  of the agreement. The  term of these agreements  is
usually  from overnight to one  week. A repurchase agreement  may be viewed as a
fully collateralized loan of money by the Portfolio to the seller. The Portfolio
always receives securities as collateral with  a market value at least equal  to
the purchase price plus accrued interest and this value is maintained during the
term  of  the  agreement. If  the  seller  defaults and  the  collateral's value
declines, the  Portfolio  might incur  a  loss. If  bankruptcy  proceedings  are
commenced  with  respect to  the seller,  the  Portfolio's realization  upon the
disposition of collateral may be
 
                                      -7-
 


<PAGE>
delayed or limited. Investments in  repurchase agreements maturing in more  than
seven  days and  certain other investments  that may be  considered illiquid are
limited. See  'Illiquid Investments;  Privately  Placed and  Other  Unregistered
Securities' below.
 
REVERSE  REPURCHASE AGREEMENTS. The Portfolio is permitted to enter into reverse
repurchase agreements. In a reverse repurchase agreement, the Portfolio sells  a
security  and agrees to repurchase it at  a mutually agreed upon date and price,
reflecting the interest  rate effective for  the term of  the agreement. It  may
also  be viewed as the borrowing of money  by the Portfolio and, therefore, is a
form of leverage. Leverage may cause any gains or losses of the Portfolio to  be
magnified.  For more  information, including limitations  on the  use of reverse
repurchase agreements, see 'Investment Objectives and Policies' in the SAI.
 
SECURITIES LENDING. Subject to applicable investment restrictions, the Portfolio
may lend its securities. The Portfolio may lend its securities if such loans are
secured continuously by cash or equivalent  collateral or by a letter of  credit
in  favor of the  Portfolio at least  equal at all  times to 100%  of the market
value of the securities loaned, plus accrued interest. While such securities are
on loan, the borrower will pay the Portfolio any income accruing thereon.  Loans
will  be subject to termination by the  Portfolio in the normal settlement time,
generally three business  days after  notice, or by  the borrower  on one  day's
notice.  Borrowed securities must  be returned when the  loan is terminated. Any
gain or loss in the market price  of the borrowed securities that occurs  during
the  term of the loan inures to  the Portfolio and its respective investors. The
Portfolio may pay reasonable  finders' and custodial fees  in connection with  a
loan.  In addition, the Portfolio will consider all the facts and circumstances,
including the creditworthiness of the  borrowing financial institution, and  the
Portfolio  will not make any loans in excess of one year. The Portfolio will not
lend its securities to any officer, Trustee, Director, employee or affiliate  or
placement  agent of the Company, the Portfolio, or the Adviser, Administrator or
Distributor, unless otherwise permitted by applicable law.
 
ILLIQUID INVESTMENTS; PRIVATELY  PLACED AND OTHER  UNREGISTERED SECURITIES.  The
Portfolio  may not acquire any illiquid securities if, as a result thereof, more
than 15% of the market value of the Portfolio's net assets would be in  illiquid
investments  or investments  that are not  readily marketable.  In addition, the
Portfolio will not invest more than 10% of the market value of its total  assets
in  restricted securities  (not including Rule  144A securities)  that cannot be
offered for public  sale in  the United  States without  first being  registered
under  the Securities Act of 1933 (the  'Securities Act'). Subject to those non-
fundamental policy limitations, the Portfolio  may acquire investments that  are
illiquid  or have limited  liquidity, such as  private placements or investments
that are not  registered under  the Securities Act,  and cannot  be offered  for
public  sale in  the United States  without first being  registered. An illiquid
investment is any investment that cannot be disposed of within seven days in the
normal course of business at approximately the  amount at which it is valued  by
the  Portfolio.  Repurchase  agreements maturing  in  more than  seven  days are
considered illiquid investments and, as such, are subject to the limitations set
forth in this paragraph. The price the Portfolio pays for illiquid securities or
receives upon resale may be  lower than the price  paid or received for  similar
securities  with  a  more liquid  market.  Accordingly, the  valuation  of these
securities will reflect any limitations on their liquidity.
 
The Portfolio  may also  purchase  Rule 144A  securities sold  to  institutional
investors without registration under the Securities Act. These securities may be
determined to be liquid in accordance with guidelines established by the Adviser
and  approved  by the  Trustees of  the Trust.  The Trustees  of the  Trust will
monitor the Adviser's implementation of these guidelines on a periodic basis.
 
MONEY MARKET INSTRUMENTS. The Portfolio is  permitted to invest in money  market
instruments  although it  intends to stay  invested in equity  securities to the
extent practical in light of its objective and long-term investment perspective.
The Portfolio may  make money  market investments pending  other investments  or
settlements,  for liquidity or  in adverse market  conditions. Such money market
investments may include obligations of the U.S. Government and its agencies  and
instrumentalities, commercial paper, bank obligations and repurchase agreements.
For  more  detailed  information  about  these  money  market  investments,  see
'Investment Objectives and Policies' in the SAI.
 
FUTURES AND OPTIONS TRANSACTIONS. The Portfolio  is permitted to enter into  the
futures and options transactions described below. These instruments are commonly
known as derivatives.
 
                                      -8-
 


<PAGE>
The Portfolio may purchase and sell exchange traded and over-the-counter ('OTC')
put and call options on equity securities or indices of equity securities, enter
into forward contracts, purchase and sell futures contracts on indices of equity
securities  and purchase or  sell put and  call options on  futures contracts on
indices of equity securities. The Portfolio may use these techniques for hedging
or risk management purposes or,  subject to certain limitations, for  investment
purposes  in  lieu  of investing  directly  in the  corresponding  securities or
instruments. Such use of derivatives may be considered speculative.
 
The Portfolio  may use  these  techniques to  manage  its exposure  to  changing
interest  rates  and/or security  prices. Some  options and  futures strategies,
including  selling  futures  contracts  and  buying  puts,  tend  to  hedge  the
Portfolio's  investments against price fluctuations. Other strategies, including
buying futures contracts, writing puts and calls, and buying calls, may tend  to
increase  market  exposure.  For  example, if  the  Portfolio  wishes  to obtain
exposure to a particular market or market  sector but does not wish to  purchase
the  relevant  securities,  it  could, as  an  alternative,  purchase  a futures
contract on an index of such  securities or related securities. Such a  purchase
would  not constitute a hedging transaction and could be considered speculative.
However, the Portfolio will use futures contracts or options in this manner only
for the purpose of obtaining the same  level of exposure to a particular  market
or  market  sector  that  it  could have  obtained  by  purchasing  the relevant
securities and  will  not use  futures  contracts  or options  to  leverage  its
exposure  beyond this  level. The  use of options  and futures  may involve some
leverage; such leverage is reduced by the requirement of the SEC to 'cover' such
obligations. See  'Cover  -- Segregated  Accounts'  below. Options  and  futures
contracts  may be combined with each other or with forward contracts in order to
adjust the risk and return  characteristics of the Portfolio's overall  strategy
in  a  manner  deemed  appropriate  to  the  Adviser  and  consistent  with  the
Portfolio's objective and policies. Because combined positions involve  multiple
trades,  they result in  higher transaction costs  and may be  more difficult to
open and close out.
 
The Portfolio's  use of  these transactions  is a  highly specialized  activity,
which  involves investment strategies and  risks different from those associated
with ordinary portfolio securities transactions,  and there can be no  guarantee
that  their use will increase the  Portfolio's return. While the Portfolio's use
of these  instruments  may  reduce  certain risks  associated  with  owning  its
portfolio securities, these techniques themselves entail certain other risks. If
the  Adviser  applies  a strategy  at  an  inappropriate time  or  judges market
conditions or  trends incorrectly,  such strategies  may lower  the  Portfolio's
return. Certain strategies limit the Portfolio's opportunity to realize gains as
well  as limiting its exposure to  losses. The Portfolio could experience losses
if the prices of its options  and futures positions were poorly correlated  with
its  other investments, or if it could not close out its positions because of an
illiquid  secondary  market.  In  addition,  the  Portfolio  will  incur  costs,
including  commissions and premiums,  in connection with  these transactions and
these transactions could significantly increase the Portfolio's turnover rate.
 
The Portfolio may purchase and sell put and call options on securities,  indices
of  securities and futures contracts, or purchase and sell futures contracts for
the purposes described herein.
 
In addition, in  order to assure  that the  Portfolio will not  be considered  a
'commodity  pool' for purposes of  Commodity Futures Trading Commission ('CFTC')
rules, the  Portfolio  will enter  into  transactions in  futures  contracts  or
options  on futures contracts only if (1) such transactions constitute bona fide
hedging transactions as defined under CFTC rules, or (2) no more than 5% of  the
Portfolio's  net assets are committed as initial margin or premiums to positions
that do not constitute bona fide hedging transactions.
 
OPTIONS
 
PURCHASING PUT  AND CALL  OPTIONS. By  purchasing a  put option,  the  Portfolio
obtains the right (but not the obligation) to sell the instrument underlying the
option at a fixed strike price. In return for this right, the Portfolio pays the
current  market price for the option (known as the option premium). Options have
various types of underlying instruments, including specific securities,  indices
of securities, indices of securities prices and futures contracts. The Portfolio
may  terminate its position in  a put option it has  purchased by allowing it to
expire or by  exercising the  option. The  Portfolio may  also close  out a  put
option  position by entering into an  offsetting transaction, if a liquid market
exists. If the option is allowed to  expire, the Portfolio will lose the  entire
premium it paid. If the Portfolio exercises a put
 
                                      -9-
 


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

<PAGE>
FUTURES CONTRACTS
 
When  the  Portfolio  purchases a  futures  contract,  it agrees  to  purchase a
specified quantity of an  underlying instrument at a  specified future date  and
price  or to make or receive  a cash payment based on  the value of a securities
index. When  the  Portfolio  sells a  futures  contract,  it agrees  to  sell  a
specified  quantity of the underlying instrument  at a specified future date and
price or to receive or  make a cash payment based  on the value of a  securities
index.  The price at which  the purchase and sale will  take place is fixed when
the Portfolio enters into the contract. Futures can be held until their delivery
dates or the positions can be (and  normally are) closed out before then.  There
is  no assurance,  however, that  a liquid  market will  exist when  a Portfolio
wishes to close out a particular position.
 
When the  Portfolio purchases  or sells  a futures  contract, the  value of  the
futures  contract tends to increase and decrease in tandem with the value of its
underlying instrument. Purchasing  futures contracts  may tend  to increase  the
Portfolio's  exposure  to  positive  and  negative  price  fluctuations  in  the
underlying instrument, much  as if  it had purchased  the underlying  instrument
directly,  as discussed above.  When the Portfolio sells  a futures contract, by
contrast, the value of  its futures position  will tend to  move in a  direction
contrary to the value of the underlying instrument. Selling futures contracts on
securities  similar  to those  held by  the Portfolio,  therefore, will  tend to
offset both  positive  and  negative  market  price  changes,  much  as  if  the
underlying instrument had been sold. Because there are a limited number of types
of  exchange-traded  options  and futures  contracts,  it is  likely  that these
standardized instruments  will  not exactly  match  the Portfolio's  current  or
anticipated  investments.  The Portfolio  may  invest in  futures  contracts and
options thereon based on securities with different issuers, maturities, or other
characteristics from  the  securities  in  which  it  typically  invests,  which
involves  a  risk  that the  options  or  futures position  will  not  track the
performance of the Portfolio's other  investments. The Portfolio may also  enter
into  transactions in futures contracts and options for non-hedging purposes, as
discussed above.
 
The purchaser or seller of a futures contract is not required to deliver or  pay
for  the underlying  instrument unless the  contract is held  until the delivery
date. However, when the Portfolio  buys or sells a  futures contract it will  be
required  to deposit 'initial margin' with the Custodian in a segregated account
in the  name of  its futures  broker,  known as  a futures  commission  merchant
('FCM').  Initial margin deposits  are typically equal to  a small percentage of
the contract's value.  If the value  of either party's  position declines,  that
party  will be required to make  additional 'variation margin' payments equal to
the change in value on a daily basis. The party that has a gain may be  entitled
to  receive all or a  portion of this amount. The  Portfolio may be obligated to
make payments of variation margin at a time when it is disadvantageous to do so.
Furthermore, it may not always  be possible for the  Portfolio to close out  its
futures positions. Until it closes out a futures position, the Portfolio will be
obligated  to continue  to pay  variation margin.  Initial and  variation margin
payments do not constitute purchasing on margin for purposes of the  Portfolio's
investment  restrictions. In the  event of the  bankruptcy of an  FCM that holds
margin on behalf of the  Portfolio, the Portfolio may  be entitled to return  of
margin  owed to it only in proportion to  the amount received by the FCM's other
customers, potentially resulting in losses to the Portfolio.
 
COVER -- SEGREGATED  ACCOUNTS. The Portfolio  will segregate liquid,  high-grade
debt  securities in connection with its use  of options and futures contracts to
the extent required by the SEC.  Securities held in a segregated account  cannot
be  sold while the  futures contract or  option is outstanding,  unless they are
replaced with other suitable  assets. As a result,  there is a possibility  that
the  segregation of  a large percentage  of the Portfolio's  assets could impede
portfolio management or the Portfolio's  ability to meet redemption requests  or
other current obligations.
 
For  further information about the Portfolio's use  of futures and options and a
more detailed discussion  of associated  risks, see  'Investment Objectives  and
Policies' in the SAI.
 
INVESTMENT RESTRICTIONS
 
The  investment  objective of  the  Fund and  the  Portfolio, together  with the
investment restrictions described  below and in  the SAI, except  as noted,  are
deemed  fundamental policies, i.e., they  may be changed only  by the 'vote of a
majority  of   the   outstanding  voting   securities'   (as  defined   in   the
 
                                      -11-
 


<PAGE>
Investment  Company Act of 1940 (the '1940 Act')), of the Fund or the Portfolio,
respectively. The Fund has  the same investment  restrictions as the  Portfolio,
except that the Fund may invest all of its investable assets in another open-end
investment  company with the same investment objective and restrictions (such as
the Portfolio). References below to the Portfolio's investment restrictions also
include the Fund's investment restrictions.
 
As a diversified investment  company, 75% of the  total assets of the  Portfolio
are  subject to the following fundamental limitations: (a) the Portfolio may not
invest more than 5%  of its total  assets in the securities  of any one  issuer,
except  U.S. Government securities; and (b) the  Portfolio may not own more than
10% of the outstanding voting securities of any one issuer.
 
The Portfolio  may not:  (i) purchase  the securities  or other  obligations  of
issuers conducting their principal business activity in the same industry if its
investments  in such industry would  exceed 25% of the  value of the Portfolio's
total assets, except  this limitation  shall not  apply to  investments in  U.S.
Government  securities; (ii) enter  into reverse repurchase  agreements or other
permitted borrowings  that  constitute senior  securities  under the  1940  Act,
exceeding  in  the aggregate  one-third of  the value  of the  Portfolio's total
assets; or (iii) borrow money, except from banks for extraordinary or  emergency
purposes,  or mortgage,  pledge or hypothecate  any assets  except in connection
with any such borrowings or  permitted reverse repurchase agreements in  amounts
up to one-third of the value of the Portfolio's total assets at the time of such
borrowing,  or purchase securities while  borrowings and other senior securities
exceed 5% of  its total  assets. For  a more  detailed discussion  of the  above
investment  restrictions, as well  as a description  of certain other investment
restrictions, see 'Investment Restrictions' and 'Additional Information' in  the
SAI.
 
MANAGEMENT
 
DIRECTORS  AND  TRUSTEES.  Pursuant to  the  Trust's Declaration  of  Trust, the
Trustees  of  the  Trust  establish   the  Portfolio's  general  policies,   are
responsible  for the overall management of the  Trust, and review the actions of
the Adviser, Administrator and other service providers. Similarly, the Directors
of the  Company set  the Company's  general policies,  are responsible  for  the
overall  management of  the Company, and  review the performance  of its service
providers. Additional information  about the  Company's Board  of Directors  and
officers  appears in  the SAI  under the  heading 'Directors  and Trustees'. The
Trustees of  the Trust  are also  the  Directors of  the Company,  which  raises
certain  conflicts  of interest.  The Company  and the  Trust have  each adopted
written procedures reasonably designed to deal with these conflicts, should they
arise. The  officers of  the Company  are  also employees  of Signature  or  its
affiliates.
 
ADVISER  AND FUNDS SERVICES AGENT. The Company  has not retained the services of
an investment adviser with respect to the Fund because the Fund seeks to achieve
its investment  objective by  investing  all of  its  investable assets  in  the
Portfolio.  The Portfolio has retained the  services of the Branch as investment
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.
 
   
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, 1996 the Bank  (including its consolidated
subsidiaries) had  total  assets  of  326.7 billion  and  equity  capital  and
reserves of 17.1 billion.
    
 
The   Adviser  provides  investment  advice  and  portfolio  management  to  the
Portfolio. Subject to  the supervision of  the Trustees, the  Adviser makes  the
Portfolio's day-to-day investment decisions, arranges
 
                                      -12-
 


<PAGE>
for   the  execution  of  portfolio   transactions  and  generally  manages  the
Portfolio's investments  and  operations.  See  'Investment  Adviser  and  Funds
Services Agent' in the SAI.
 
The  Adviser  uses  a  sophisticated,  disciplined,  collaborative  process  for
managing all asset classes.  Nancy C. Tengler is  primarily responsible for  the
day-to-day  management  and  implementation  of the  Adviser's  process  for the
Portfolio. Ms. Tengler is also the Managing Director -- Senior Portfolio Manager
of UBS Asset  Management (New York)  Inc.'s Value Equities  Group. She has  held
this position since December 1994. Previously, Ms. Tengler was the President and
Senior  Portfolio Manager  for Spare Tengler  Kaplan & Bischel  from August 1989
through June  1994. Ms.  Tengler is  currently managing  several portfolios  and
researching  investment  opportunities  in  several  industries,  including  the
pharmaceutical and business services industries. Ms. Tengler co-authored a  book
entitled  Relative  Dividend  Yield --  Common  Stock Investing  for  Income and
Appreciation, and has thirteen years  of investment experience. Ms. Tengler  has
previously managed the investments of a mutual fund. Ms. Tengler received a B.A.
degree  from Point Loma College. The Branch  has not previously advised a mutual
fund,  but  has  considerable   experience  managing  portfolios  with   similar
investment objectives. This may be viewed as a risk of investing in this Fund.
 
In  addition to the  above-listed investment advisory  services, the Branch also
provides  the  Fund  and  the  Portfolio  with  certain  related  administrative
services.   Subject  to   the  supervision   of  the   Directors  and  Trustees,
respectively, the Branch is responsible for: establishing performance  standards
for  the third-party service providers of  the Fund and Portfolio and overseeing
and evaluating  the  performance  of such  entities;  providing  and  presenting
quarterly  management reports to the Directors and the Trustees; supervising the
preparation of reports  for Fund  and Portfolio  shareholders; and  establishing
voluntary  expense limitations for the Fund  and providing any resultant expense
reimbursement to the Fund.
 
The Branch provides its administrative services to the Fund pursuant to a  Funds
Services  Agreement  between the  Branch and  the Company.  The Branch  does not
receive a fee from the  Company or the Fund pursuant  to the terms of the  Funds
Services Agreement.
 
Under  the Trust's Investment Advisory Agreement, the Portfolio pays the Adviser
a fee, calculated daily and payable monthly, equal, on an annual basis, to 0.60%
of the Portfolio's average daily net  assets. The Branch has voluntarily  agreed
to  waive its  fees and reimburse  the Fund and  the Portfolio for  any of their
respective direct and  indirect expenses  to the  extent that  the Fund's  total
operating  expenses (including its share of the Portfolio's expenses) exceed, on
an annual basis, 0.90% of  the Fund's average daily  net assets. The Branch  may
modify  or discontinue this fee waiver and expense limitation at any time in the
future with 30 days' prior notice to the Fund. See 'Expenses'.
 
INVESTMENTS IN THE FUND ARE NOT  DEPOSITS WITH OR OBLIGATIONS OF, OR  GUARANTEED
OR ENDORSED BY, THE BRANCH OR ANY OTHER BANK.
 
ADMINISTRATORS.  Under Administrative  Services Agreements with  the Company and
the Trust, Signature  and Signature-Cayman  serve as the  Administrators of  the
Fund and the Portfolio, respectively (in such capacities, the 'Administrators').
In  these capacities, Signature  and Signature-Cayman administer  all aspects of
the Fund's and the Portfolio's day-to-day operations, subject to the supervision
of the Adviser and the Directors and Trustees, respectively, except as set forth
under  'Adviser  and  Funds  Services  Agent',  'Distributor',  'Custodian'  and
'Shareholder Services'. The Administrators (i) furnish general office facilities
and  ordinary clerical and related  services for day-to-day operations including
recordkeeping responsibilities; (ii) take responsibility for compliance with all
applicable federal and state securities  and other regulatory requirements;  and
(iii)  perform administrative and managerial oversight  of the activities of the
custodian, transfer agent  and other  agents or independent  contractors of  the
Fund  and the Portfolio. Signature is also responsible for monitoring the Fund's
status as a  regulated investment  company under  the Internal  Revenue Code  of
1986, as amended (the 'Code').
 
Under  the Company's Administrative  Services Agreement, the  Fund has agreed to
pay Signature a fee, calculated daily  and payable monthly, equal, on an  annual
basis,  to 0.05% of the  Fund's first $100 million  average daily net assets and
0.025% of the  next $100 million  average daily net  assets. Signature does  not
receive  a fee  from the  Fund on  average daily  net assets  in excess  of $200
million.

<PAGE>
Under the Trust's Administrative Services Agreement, the Portfolio has agreed to
pay Signature-Cayman a fee, calculated daily  and payable monthly, equal, on  an
annual basis, to 0.05% of the Portfolio's average daily net assets.
 
DISTRIBUTOR. Under the Distribution Agreement, Signature, located at 6 St. James
Avenue,  Boston, MA  02116, serves  as the distributor  of Fund  shares (in such
capacity,  the  'Distributor').  The   Distributor  is  a  wholly-owned   direct
subsidiary of Signature Financial Group, Inc. and is a registered broker-dealer.
The Distributor does not receive a fee pursuant to the terms of the Distribution
Agreement.
 
CUSTODIAN.  Investors Bank & Trust Company,  whose principal offices are located
at 89 South Street, Boston, Massachusetts 02111, serves as the custodian for the
Portfolio and the Fund and transfer and dividend disbursing agent for the  Fund.
See  'Custodian' in  the SAI.  The Custodian also  maintains offices  at 1 First
Canadian Place, Suite 2800, Toronto, Ontario M5X1C8.
 
SHAREHOLDER SERVICES
 
The Company has entered into a shareholder servicing agreement with the  Branch,
and  may enter into additional shareholder servicing agreements with one or more
financial institutions (together with the Branch, 'Eligible Institutions')  such
as   a  federal  or  state-chartered  bank,  trust  company,  savings  and  loan
association or  savings bank,  or broker-dealer.  Pursuant to  each  shareholder
servicing agreement, an Eligible Institution, as agent for its customers who are
purchasing  shares of  the Fund, will  perform the following  services for these
investors, among other  things: coordinating shareholder  accounts and  records,
assisting  investors  seeking  to  purchase  or  redeem  Fund  shares, providing
performance information  relating to  the Fund,  and responding  to  shareholder
inquiries.  The Company has  agreed to pay  each Eligible Institution  a fee for
these services equal,  on an annual  basis, to  0.25% of the  average daily  net
assets of the Fund represented by shares of the Fund owned during the period for
which  payment is being made by customers of the Eligible Institution. Under the
terms  of  the  shareholder  servicing  agreements,  Eligible  Institutions  may
delegate  one  or more  of  their responsibilities  to  other entities  at their
expense.
 
EXPENSES
 
   
In addition  to  the  fees  of  the  Branch,  Signature,  Signature-Cayman,  and
Investors Bank & Trust Company, the Fund will be responsible for other expenses,
including  brokerage costs and litigation and extraordinary expenses. The Branch
has voluntarily  agreed to  limit  the total  operating  expenses of  the  Fund,
excluding  extraordinary  expenses, to  an annual  rate of  0.90% of  the Fund's
average daily net assets.  The Branch may modify  or discontinue this  voluntary
expense  limitation at any time in the future  with 30 days' prior notice to the
Fund.
    
 
The Fund  and  the  Portfolio  may  allocate  brokerage  transactions  to  their
affiliates and the Adviser's affiliates only if the commissions received by such
affiliates  are fair  and reasonable  when compared  to the  commissions paid to
unaffiliated brokers in connection with comparable transactions. See  'Portfolio
Transactions' in the SAI.
 
PURCHASE OF SHARES
 
GENERAL  INFORMATION  ON  PURCHASES.  Investors may  purchase  Fund  shares only
through  the  Distributor.  All  purchase   orders  must  be  accepted  by   the
Distributor.  The  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 Fund may be purchased only in those states where
they may be lawfully sold.
 
The business days of the Fund and the Portfolio are the days the New York  Stock
Exchange (the 'NYSE') is open for regular trading.
 
                                      -14-



<PAGE>
The  shares of the Fund are sold on a continuous basis without a sales charge at
the net asset value per share next determined after receipt and acceptance of  a
purchase  order by the Distributor.  The Fund calculates its  net asset value at
the close of business. See 'Net Asset Value'. The minimum initial investment  in
the  Fund is $25,000, except that the  minimum initial investment is $10,000 for
shareholders of another series of the Company. The minimum subsequent investment
in the Fund  for all  investors is $5,000.  The minimum  initial investment  for
employees  of  the Bank  or  its affiliates  is  $5,000. The  minimum subsequent
investment is $1,000. For purposes  of the minimum investment requirements,  the
Fund may aggregate investments by related shareholders. These minimum investment
requirements  may be waived at the Fund's discretion. 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  investor's  subscription  is  accepted.  See
'Purchase of Shares' in the SAI.
 
Purchase  orders in proper form  received by the Distributor  prior to 4:00 p.m.
New York time or the close of regular trading on the NYSE, whichever is earlier,
are effective and  executed at  the net asset  value next  determined that  day.
Purchase orders received after 4:00 p.m. New York time or the close of the NYSE,
whichever  is earlier, will be executed at the net asset value determined on the
next business day. Investors become record  shareholders of the Fund on the  day
they  place their subscription order, provided it is received by the Distributor
before 4:00  p.m.  As  record  shareholders,  investors  are  entitled  to  earn
dividends.  Settlement date  for purchases  is the  next business  day following
trade date.
 
Customers of  Eligible Institutions  should request  a representative  of  their
Eligible  Institution  to  assist them  in  placing  a purchase  order  with the
Distributor. Shareholders who do not  currently maintain a relationship with  an
Eligible  Institution  may  purchase  shares  of  the  Fund  directly  from  the
Distributor by wire transfer or mail.
 
The Transfer Agent will maintain the accounts for all shareholders who  purchase
Fund  shares directly through  the Distributor. For  account balance information
and shareholder services, such shareholders should contact the Transfer Agent at
(888) UBS-FUND or in writing at UBS Private Investor Funds, Inc., c/o  Investors
Bank & Trust Company, P.O. Box 1537 MFD 23, Boston, MA 02205-1537.
 
By  wire: Purchases may be made by federal funds wire. To place a purchase order
with the  Fund, the  shareholder  must telephone  the  Transfer Agent  at  (888)
UBS-FUND for specific instructions.
 
Subject  to the minimum purchase  requirements discussed above, shares purchased
by federal funds wire  will be effected  at the net asset  value per share  next
determined after acceptance of the order.
 
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 shareholder's  account number
must be clearly marked on the check to ensure proper credit.
 
By  mail:  Subject  to  the  minimum  purchase  requirements  discussed   above,
shareholders  may  purchase  shares  of  the  Fund  through  the  Distributor by
completing an account application and mailing it, together with a check  payable
to  'UBS Private Investor Funds, Inc.', to UBS Private Investor Funds, Inc., c/o
Investors Bank & Trust Company, P.O. Box 1537 MFD 23, Boston, MA 02205-1537.
 
Checks are subject to collection at  full value. For shares purchased by  check,
dividend  payments and redemption  proceeds, if any, will  be delayed until such
funds are collected, which may take up to 15 days from the date of purchase.
 
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.  The Fund calculates its net asset  value at the close of business.
See 'Net Asset Value'.

A redemption order will  be effected provided the  Distributor receives such  an
order  prior to 4:00 p.m. New  York time or the close  of regular trading on the
NYSE, whichever is earlier.  The redemption of Fund  shares is effective and  is
executed  at the  net asset  value next  determined that  day. Redemption orders
received after 4:00 p.m. New  York time or the close  of regular trading on  the
NYSE,  whichever is earlier, will be executed  at the net asset value determined
on the next  business day.  Proceeds of  an effective  redemption are  generally
deposited  the next business  day in immediately available  funds to the account
designated by the redeeming shareholder  or mailed to the shareholder's  address
of record, in accordance with the shareholder's instructions.
 
Shareholders  will not be record  holders for dividend purposes  on the day that
they redeem Fund shares.
 
Customers of  Eligible  Institutions  must request  a  representative  of  their
Eligible  Institution to assist them in placing a redemption order. Shareholders
whose accounts are maintained  by the Transfer Agent  may redeem Fund shares  by
telephone or mail.
 
By telephone: Telephone redemptions may be made by calling the Transfer Agent at
(888) UBS-FUND. Redemption orders will be accepted until 4:00 p.m. New York time
or  the close of  regular trading on  the NYSE, whichever  is earlier. Telephone
redemption requests  are  limited  to those  shareholders  who  have  previously
elected  this service.  Such shareholders  risk possible  loss of  principal and
income in the event of a telephone  redemption not authorized by them. The  Fund
and  the  Transfer  Agent  will  employ  reasonable  procedures  to  verify that
telephone redemption instructions are genuine and will require that shareholders
electing such an option provide a  form of personal identification. The  failure
by  the Fund or the Transfer Agent to  employ such procedures may cause the Fund
or the Transfer Agent to be liable  for any losses incurred by investors due  to
telephone  redemptions based  upon unauthorized or  fraudulent instructions. The
telephone redemption option may be modified or discontinued at any time upon  60
days' notice to shareholders.
 
By  mail:  Redemption  requests  may  also  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, 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.
The redemption request  in proper form  should be sent  to UBS Private  Investor
Funds,  Inc., c/o Investors Bank & Trust  Company, P.O. Box 1537 MFD 23, Boston,
MA 02205-1537.
 
MANDATORY REDEMPTION. If the value of a shareholder's holdings in the Fund falls
below $10,000 because  of a  redemption of shares,  the shareholder's  remaining
shares  may  be redeemed  60 days  after  written notice  unless the  account is
increased to $10,000 or more. For example, a shareholder whose initial and  only
investment  is $10,000 may be subject to mandatory redemption resulting from any
redemption that causes his or her investment to fall below $10,000.
 
FURTHER REDEMPTION INFORMATION. Investors should  be aware that redemptions  may
not  be processed unless the redemption request  is submitted in proper form. To
be in  proper form,  the  Fund must  have  received the  shareholder's  taxpayer
identification  number and address.  As discussed under  'Taxes' below, the Fund
may be  required  to impose  'back-up'  withholding  of federal  income  tax  on
dividends,  distributions and redemptions when  non-corporate investors have not
provided a certified taxpayer identification number. In addition, if an investor
sends a check to the Distributor for the purchase of Fund shares and shares  are
purchased  with funds  made available  by the  Distributor before  the check has
cleared, the transmittal of  redemption proceeds from the  sale of those  shares
will  not occur until the check used  to purchase such shares has cleared, which
may take up to 15 days. Redemption delays may be avoided by purchasing shares by
federal funds wire.
 
                                      -16-
 


<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.  For  investors  in  certain  states,  state
securities laws may restrict the availability of the exchange privilege.
 
RETIREMENT PLANS
 
The  Fund  has available  a form  of Individual  Retirement Account  ('IRA') for
investment in Fund shares. Subject to certain restrictions imposed by applicable
tax laws,  self-employed individuals  may purchase  shares of  the Fund  through
tax-deductible contributions to existing retirement plans known as Self-Employed
Retirement  Plans ('SERPs'). Fund  shares may also be  a suitable investment for
'401(k) Plans' which subject to certain restrictions allow their participants to
invest in qualified  pension plans on  a tax-deferred basis.  The Fund does  not
currently act as sponsor to such plans.
 
The  minimum initial  investment for  all such  retirement plans  is $2,000. The
minimum for all subsequent investments is $500.
 
Under the 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  $2,250 annually to one or both
IRAs provided that no more than $2,000  may be contributed to the IRA of  either
spouse.
 
Investors  should be aware that  they may be subject  to penalties or additional
taxes on contributions  to or withdrawals  from IRAs or  other retirement  plans
under certain circumstances. Prior to a withdrawal, shareholders may be required
to  certify  as to  their age  and  awareness of  such restrictions  in writing.
Clients of  Eligible Institutions  desiring information  concerning  investments
through   IRAs  or  other   retirement  plans  should   contact  their  Eligible
Institution. Clients  who  do  not  maintain a  relationship  with  an  Eligible
Institution  may obtain such information by  calling the Transfer Agent at (888)
UBS-FUND.
 
DIVIDENDS AND DISTRIBUTIONS
 
Dividends consisting of substantially all  of the Fund's net investment  income,
if  any, are declared and paid annually. The Fund may also declare an additional
dividend of net investment  income in a  given year to  the extent necessary  to
avoid the imposition of federal excise taxes on the Fund.
 
Substantially  all of  the Fund's  realized net capital  gains, if  any, will be
declared and paid on  an annual basis, except  that an additional capital  gains
distribution  may be made in  a given year to the  extent necessary to avoid the
imposition  of  federal  excise  taxes  on  the  Fund.  Declared  dividends  and
distributions  are payable on the payment date  to shareholders of record on the
record date.
 
                                      -17-
 


<PAGE>
Dividends and capital  gains distributions  paid by the  Fund are  automatically
reinvested  in additional  Fund shares  unless the  shareholder has  elected, in
writing, to have them paid  in cash. Dividends and  distributions to be paid  in
cash  are credited to the account designated by the shareholder or sent by check
to the shareholder's  address of  record, in accordance  with the  shareholder's
instructions.  The Fund  reserves the right  to discontinue, alter  or limit the
automatic reinvestment privilege at any time.
 
NET ASSET VALUE
 
The Fund's net asset value per share equals the value of the Fund's total assets
(i.e., the value of its investment in the Portfolio plus its other assets)  less
the  amount of its liabilities, divided by the number of its outstanding shares,
rounded to the nearest cent. Expenses, including the fees payable to the service
providers of the Fund and the Portfolio, are accrued daily. Securities for which
market quotations are readily  available are valued at  market value. All  other
securities  will be valued at 'fair value'. See 'Net Asset Value' in the SAI for
information on the valuation of the Portfolio's assets and liabilities.
 
The Fund computes its  net asset value  once daily at the  close of business  on
Monday  through Friday, except that the net  asset value is not computed for the
Fund on a day  in which no orders  to purchase or redeem  Fund shares have  been
received or on any day on which the New York Stock Exchange is closed, including
the  following holidays: New Year's Day,  Presidents' Day, Good Friday, Memorial
Day, Independence Day, Labor  Day, Thanksgiving Day and  Christmas Day. On  days
when  U.S. trading markets close early in observance of these holidays, the Fund
expects to close for purchases and redemptions at the same time.
 
ORGANIZATION
 
UBS PRIVATE INVESTOR FUNDS, INC.
 
UBS Private  Investor  Funds,  Inc.,  a  Maryland  corporation  incorporated  on
November 16, 1995, is an open-end management investment company registered under
the 1940 Act and organized as a series fund. The Company is currently authorized
to  issue shares in  four series: The UBS  Bond Fund Series;  The UBS Tax Exempt
Bond Fund Series;  The UBS International  Equity Fund Series;  and The UBS  U.S.
Equity  Fund Series. Each outstanding share of  the Company will have a pro rata
interest in the assets of its series, but it will have no interest in the assets
of any other Company series. Only shares of The UBS U.S. Equity Fund Series  are
offered through this Prospectus.
 
Shareholder  inquiries by  clients of Eligible  Institutions may  be directed to
their Eligible Institution and other shareholders may address their inquiries to
the Transfer Agent.
 
Shareholders of the  Fund are entitled  to one vote  for each share  and to  the
appropriate  fractional vote for  each fractional share.  There is no cumulative
voting. Shares have no  preemptive or conversion rights.  Shares are fully  paid
and  nonassessable when issued  by the Company.  The Company does  not intend to
hold meetings  of shareholders  annually.  The Directors  may call  meetings  of
shareholders  for action by shareholder vote as  may be required by its Articles
of Incorporation  or  the  1940 Act.  For  further  organizational  information,
including certain shareholder rights, see 'Organization' in the SAI.
 
UBS INVESTOR PORTFOLIOS TRUST
 
UBS  Investor Portfolios Trust, a  master trust fund formed  under New York law,
was organized on February 9, 1996. The Declaration of Trust permits the Trustees
to issue interests divided into one or more subtrusts or series. To date,  three
series have been authorized, of which UBS U.S. Equity Portfolio is one.
 
The  Declaration  of  Trust  provides  that  no  Trustee,  shareholder, officer,
employee, or agent of  the Trust shall  be held to  any personal liability,  nor
shall  resort be had to  such person's private property  for the satisfaction of
any obligation  or claim  or otherwise  in connection  with the  affairs of  the
Portfolio, but that only the Trust property shall be liable.
 
                                      -18-
 


<PAGE>
The  Declaration of Trust provides that the Fund and other entities investing in
the Portfolio  (e.g., other  investment  companies, insurance  company  separate
accounts  and common and commingled trust funds) will each be liable for all the
obligations of  the  Portfolio.  However,  the  risk  of  the  Fund's  incurring
financial loss on account of such liability is limited to circumstances in which
both  inadequate insurance existed  and the Portfolio itself  was unable to meet
its obligations. Accordingly, the Trustees believe that neither the Fund nor its
shareholders will be adversely  affected by reason of  the Fund's investment  in
the Portfolio.
 
TAXES
 
Each  Fund  has  qualified  and  intends  to  remain  qualified  as  a regulated
investment company (a 'RIC') under  Subchapter M of the Code.  As a RIC, a  Fund
(as  opposed to its shareholders) will not be subject to federal income taxes on
the net  investment  income  and  capital  gains  that  it  distributes  to  its
shareholders,  provided  that at  least  90% of  its  net investment  income and
realized net short-term capital gains in excess of net long-term capital  losses
for  the taxable  year is  distributed. The  Portfolio intends  to qualify  as a
partnership for federal income  tax purposes. As  such, the Portfolio  generally
should  not be subject to tax. The status  of the Fund as a regulated investment
company  is  dependent  on,  among  other  things,  the  Portfolio's   continued
qualification as a partnership for federal income tax purposes.
 
Dividends  from  net  investment  income  and  distributions  from  realized net
short-term capital gains in excess of  net long-term capital losses are  taxable
as  ordinary income to Fund shareholders whether such distributions are received
in the form  of cash  or reinvested  in additional  shares. To  the extent  that
dividends  distributed to shareholders are designated as derived from the Fund's
dividend income that would be eligible  for the dividends received deduction  if
the  Fund were not a regulated  investment company, such dividends are eligible,
subject to certain restrictions,  for the 70%  dividends received deduction  for
corporations.  Distributions of  net long-term  capital gains  in excess  of net
short-term capital losses are taxable to Fund shareholders as long-term  capital
gains  regardless of  how long  a shareholder  has held  shares in  the Fund and
regardless of whether received in the  form of cash or reinvested in  additional
shares.  Long-term capital gains distributions to corporate shareholders are not
eligible for  the  dividends-received deduction.  Annual  statements as  to  the
current federal tax status of distributions will be mailed to shareholders after
the end of the taxable year for the Fund.
 
Any  gain or  loss realized on  the redemption or  exchange of Fund  shares by a
shareholder who  is not  a dealer  in securities  generally will  be treated  as
long-term  capital gain or loss  if the shares have been  held for more than one
year, and  otherwise as  short-term  capital gain  or  loss. However,  any  loss
realized  by a shareholder upon the redemption or exchange of shares in the Fund
held for six months or less will be  treated as a long-term capital loss to  the
extent  of any long-term capital gain  distributions received by the shareholder
with respect to such shares. In addition, no loss will be allowed on the sale or
other disposition of shares  of the Fund  if, and to the  extent that, within  a
period  beginning 30 days before the date of such sale or disposition and ending
30 days  after  such  date,  the  holder  acquires  (such  as  through  dividend
reinvestment)  securities that are substantially identical  to the shares of the
Fund.
 
The Fund will generally be subject to an  excise tax of 4% on the amount of  any
income  or  capital  gains,  above  certain  permitted  levels,  distributed  to
shareholders on  a  basis such  that  such income  or  gain is  not  taxable  to
shareholders  in  the  calendar  year  in  which  it  was  earned  by  the Fund.
Furthermore, dividends declared  in October,  November, or  December payable  to
shareholders  of record  on a  specified date in  such a  month and  paid in the
following January will be treated as having  been paid by the Fund and  received
by each shareholder in December. Under this rule, therefore, shareholders may be
taxed  in one year on dividends or distributions actually received in January of
the following year.
 
Distributions of net investment income or net long-term capital gains will  have
the effect of reducing the net asset value of the Fund's shares by the amount of
the  distribution. If the net asset value is reduced 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.
 
                                      -19-
 


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

FOR INFORMATION CALL (800) 914-8566
 
UBS  International Equity Fund (the '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  take advantage of  investment
opportunities outside the United States.

charges or exchange or redemption fees. The Fund is one of several series of UBS
Private Investor Funds, Inc. (the 'Company'), an open-end management  investment
company organized as a corporation under Maryland law.
 
UNLIKE  OTHER MUTUAL FUNDS THAT DIRECTLY  ACQUIRE AND MANAGE THEIR OWN PORTFOLIO
OF SECURITIES, THE FUND SEEKS TO  ACHIEVE ITS INVESTMENT OBJECTIVE BY  INVESTING
ALL  OF  ITS  INVESTABLE  ASSETS  IN  UBS  INTERNATIONAL  EQUITY  PORTFOLIO (THE
'PORTFOLIO'). THE PORTFOLIO IS  A SERIES OF UBS  INVESTOR PORTFOLIOS TRUST  (THE
'TRUST'),  AN OPEN-END MANAGEMENT INVESTMENT COMPANY. THE PORTFOLIO HAS THE SAME
INVESTMENT OBJECTIVE  AS THE  FUND. THE  FUND EMPLOYS  A TWO-TIER  MASTER-FEEDER
INVESTMENT  FUND  STRUCTURE  THAT  IS MORE  FULLY  DESCRIBED  UNDER  THE SECTION
CAPTIONED 'MASTER-FEEDER STRUCTURE'.
 
The Portfolio is advised by the New York Branch (the 'Branch' or the  'Adviser')
of  Union  Bank of  Switzerland (the  'Bank')  and UBS  International Investment
London  Limited  (the  'Sub-Adviser'  and,   together  with  the  Adviser,   the
'Advisers').
 
   
This  Prospectus  sets forth  concisely the  information about  the Fund  that a
prospective investor  ought to  know before  investing. It  should be  read  and

UBS INTERNATIONAL EQUITY FUND
INVESTORS FOR WHOM THE FUND IS DESIGNED
 
UBS International Equity Fund (the 'Fund') is designed for investors who want to
participate in the risks and returns associated with equity securities issued by
foreign  corporations. The  Fund seeks  to achieve  its investment  objective by
investing all of  its investable  assets in UBS  International Equity  Portfolio
(the  'Portfolio'). The Portfolio  is a series of  UBS Investor Portfolios Trust
(the 'Trust'), an open-end management investment company. The Portfolio has  the
same  investment objective as  the Fund. Because  the investment characteristics
and experience of the Fund will correspond directly with those of the Portfolio,
the discussion  in this  Prospectus focuses  on the  investments and  investment
policies  of the Portfolio. The net asset value of shares of the Fund fluctuates
with changes in the value of the investments in the Portfolio.
 
The Portfolio may make  various types of investments  in seeking its  objective.
Among  the permissible investments for the Portfolio are common stocks and other
securities  with  equity  characteristics  issued  by  foreign  companies.   The
Portfolio  may also invest  in futures contracts,  options, forward contracts on
foreign currencies  and certain  privately  placed securities.  The  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  Objective
and Policies' discussed below.
 
The  minimum initial investment in the Fund  is $25,000, except that the minimum
initial investment is $10,000 for shareholders of another series of UBS  Private
Investor  Funds, Inc. (the 'Company'). The minimum subsequent investment for all
investors is $5,000. These minimums may be waived at the Fund's discretion.  See
'Purchase of Shares'. If shareholders reduce their total investment in shares of
the  Fund to less  than $10,000, their  investment will be  subject to mandatory
redemption. See 'Redemption of Shares -- Mandatory Redemption'. The Fund is  one
of  several series  of the  Company, an  open-end management  investment company
organized as a Maryland corporation.
 
This Prospectus describes the investment objective and policies, management  and
operations  of the Fund  to enable investors  to decide if  the Fund suits their
investment needs. The Fund operates through a two-tier master-feeder  investment
fund  structure.  The  Company's  Board of  Directors  (the  'Directors'  or the
'Board') believes  that  this  structure provides  Fund  shareholders  with  the
opportunity  to  achieve  certain economies  of  scale that  would  otherwise be
unavailable  if  the  shareholders'  investments  were  not  pooled  with  other
investors sharing similar investment objectives.
 
The  following table illustrates that investors in the Fund incur no shareholder
transaction expenses: their  investments in  the Fund  are subject  only to  the
operating  expenses  set  forth below  for  the  Fund and  the  Portfolio,  as a
percentage of average daily net assets  of the Fund. The Directors believe  that
the  aggregate  per  share  expenses  of the  Fund  and  the  Portfolio  will be
approximately equal to and  may be less  than the expenses  that the Fund  would
incur  if it  retained the  services of an  investment adviser  and invested its
assets directly  in  portfolio  securities.  Fund  and  Portfolio  expenses  are
discussed  below under  the headings  'Management', 'Expenses'  and 'Shareholder
Services'.

*    Expenses are  expressed as  a percentage of  the Fund's  average daily  net
assets  and are based on  the expenses incurred during  the period April 2, 1996
(commencement of operations) through December 31, 1996, after any applicable fee
waivers and  expense  reimbursements.  Without  such  fee  waivers  and  expense
reimbursements,  Total Operating Expenses would be equal, on an annual basis, to
3.05% of the Fund's average daily net assets. See 'Management'.
    
 
   
**   The New  York Branch  (the  'Branch' or  the 'Adviser')  of Union  Bank  of
Switzerland (the 'Bank') has agreed to waive fees and reimburse the Fund for any
of its operating expenses to the extent that the Fund's total operating expenses
(including  its share of  the Portfolio's expenses) exceed,  on an annual basis,
95% of the Fund's average daily net assets. The Branch may modify or discontinue
this undertaking at any  time in the  future with 30 days'  prior notice to  the
Fund.  The Portfolio's advisory fee would be equal, on an annual basis, to 0.85%
of the average daily net assets of the Portfolio if there were no fee waiver  in
effect. See 'Management -- Adviser and Funds Services Agent' and 'Expenses'.
    
 
***  The fees and expenses  in Other Expenses include  fees payable to Signature
Broker-Dealer Services,  Inc.  ('Signature') under  an  Administrative  Services
Agreement  with  the  Fund, fees  payable  to Signature  Financial  Group (Grand
Cayman) Ltd.  ('Signature-Cayman') under  an Administrative  Services  Agreement
with  the  Portfolio,  fees  payable  to Investors  Bank  &  Trust  Company (the
'Custodian' or the 'Transfer Agent') as custodian of the Fund and the  Portfolio
and  transfer  agent of  the  Fund, and  fees payable  by  the Fund  to Eligible
Institutions providing shareholder services under various shareholder  servicing
agreements.  For a  more detailed  description of  contractual fee arrangements,
including fee waivers and expense reimbursements,  and of the fees and  expenses

HISTORICAL PERFORMANCE OF COMPARABLE DISCRETIONARY ACCOUNTS. The following table
sets forth (i) the composite average annual total returns for the one, three and
five year  periods  ended  December  31,  1996 and the period from April 1, 1987
(commencement of operations of the relevant  accounts) through December 31, 1996
for all  discretionary  accounts  described  below that have been managed for at
least one full  quarter by UBS  International  Investment  London  Limited  (the
'Sub-Adviser'), (ii) the average annual return for the Fund for the period April
2, 1996  (commencement  of operations)  through  December 31, 1996 and (iii) the
average  annual  total  return  during the same  periods for the Morgan  Stanley
Capital  International  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 Portfolio. The composite total
returns for such  accounts have been adjusted to deduct all of the Fund's annual
total  operating  expenses of 1.39% of average  daily net assets as set forth in
the Fee Table above.  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
    
 
                                      -4-
 


<PAGE>
discretionary  accounts  are   not  subject to  certain investment  limitations,
diversification   requirements   and   other   restrictions  imposed  by federal
securities and tax laws on the Portfolio that, if applied  to the  accounts, may
have  adversely  affected  their  performance  results. The Sub-Adviser believes
that the restatement of  total returns prior to 1994  would not  result  in  any
material changes in  the total returns  shown. The  composite  total  returns of
these discretionary accounts does not represent  the  historical  performance of
the Portfolio and should not be viewed as a prediction of future performance  of
the Portfolio.  The Morgan  Stanley  Capital  International   EAFE  Index   (the
'Index')  is an unmanaged  index that  measures   stock  performance  in Europe,
Australia  and the  Far East.  The total  returns of  the Index  do  not include
management fees or commissions.

MASTER-FEEDER STRUCTURE
 
Unlike  other mutual funds that directly  acquire and manage their own portfolio
of securities, the Fund seeks to  achieve its investment objective by  investing
all  of its  investable assets in  the Portfolio, a  separate investment company
with the same investment objective as the Fund. The investment objective of  the
Fund and the Portfolio may be changed only with the approval of the holders of a
majority  of the outstanding voting securities of  the Fund or a majority of the
investors in the Portfolio, respectively, after 30 days' prior notice.
 
This  master-feeder  structure  has  been  developed  relatively  recently,   so
shareholders should carefully consider this investment approach.
 
In  addition to selling an interest in  the Portfolio to the Fund, the Portfolio
may sell  interests in  the Portfolio  to other  mutual funds  or  institutional
investors.  Such investors will  invest in the  Portfolio on the  same terms and
conditions as the  Fund and will  pay a proportionate  share of the  Portfolio's
expenses.  However, other entities investing in the Portfolio may sell shares of
their own  fund  using a  different  pricing  structure than  the  Fund's.  Such
different pricing structures may result in differences in returns experienced by
investors  in  other funds  that invest  in the  Portfolio. Such  differences in
returns are  not uncommon  and  are present  in  other mutual  fund  structures.
Information  concerning other holders of interests in the Portfolio is available
from Signature at (617) 423-0800.
 
The Fund may withdraw its investment in  the Portfolio at any time if the  Board
determines  that it  is in  the Fund's  best interest  to do  so. Upon  any such
withdrawal, the Board would consider what  action might be taken, including  the
investment  of all the Fund's assets  in another pooled investment entity having
the same investment objective and restrictions  as the Fund or the retaining  of
an  investment  adviser  to manage  the  Fund's  assets in  accordance  with the
investment policies described below with respect to the Portfolio.
 
Certain  changes   in  the   Portfolio's  investment   objective,  policies   or
restrictions, or a failure by the Fund's shareholders to approve a change in the
Portfolio's  investment  objective  or  restrictions, may  require  the  Fund to
withdraw its investments in the Portfolio.  Any such withdrawal could result  in
an   in-kind  distribution  of  portfolio  securities  (as  opposed  to  a  cash
distribution) by  the  Portfolio  to  the  Fund.  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  the Fund's having
a less diversified portfolio of
 
                                      -5-
 


<PAGE>
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  th e above,  there  are  other  means  for  meeting shareholder
redemption requests, such as borrowing.
 
Smaller  funds  investing in  the Portfolio  may be  materially affected  by the
actions of larger funds investing in the Portfolio. For example, if a large fund
withdraws from the  Portfolio, the remaining  funds may subsequently  experience
higher  pro  rata operating  expenses,  thereby lowering  returns. Additionally,
because the  Portfolio would  become smaller,  it may  become less  diversified,
resulting  in potentially increased portfolio risk (however, these possibilities
also exist for traditionally structured  funds that have large or  institutional
investors  who may withdraw  from a fund).  Also, funds with  a greater pro rata
ownership  in  the  Portfolio  could  have  effective  voting  control  of   its
operations.  Except as permitted by the  Securities and Exchange Commission (the
'SEC'), whenever the  Fund is  requested to vote  on matters  pertaining to  the
Portfolio,  the Company will hold  a meeting of Fund  shareholders and will cast
Fund votes  proportionately  as  instructed  by  the  Fund's  shareholders.  See
'Organization' in the SAI. Fund shareholders who do not vote will not affect the
Fund's  votes at  the Portfolio meeting.  The percentage of  the Company's votes
representing Fund shareholders not  voting will be voted  by the Company in  the
same proportion as the Fund shareholders who do, in fact, vote.
 
For  more information about  the Portfolio's investment  objective, policies and
restrictions, see 'Investment  Objective and  Policies', 'Additional  Investment
Information   and  Risk   Factors'  and  'Investment   Restrictions'.  For  more
information about the Portfolio's management and expenses, see 'Management'. For
more  information  about  changing   the  investment  objective,  policies   and
restrictions of the Fund or the Portfolio, see 'Investment Restrictions'.
 
INVESTMENT OBJECTIVE AND POLICIES
 
The  investment  objective of  the Fund  and the  Portfolio is  described below,
together with  the policies  each  employs to  seek  to achieve  its  objective.
Additional  information  about  the  investment policies  of  the  Fund  and the
Portfolio appears in the SAI under Investment Objectives and Policies. The  Fund
seeks  to achieve  its investment objective  by investing all  of its investable
assets in the Portfolio,  which has the same  investment objective as the  Fund.
There  can be  no assurance  that the  investment objective  of the  Fund or the
Portfolio will be achieved.
 
The 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
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 Portfolio  seeks  to  achieve  its  investment  objective  by  investing  in
companies  that the  Sub-Adviser believes are  fundamentally sound  and that are
typically selling at below market  valuations and that the Sub-Adviser  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.
 
The  Adviser is  responsible for supervising  the management  of the Portfolio's
investments. Consistent  with  these duties,  the  Adviser has  entered  into  a
Sub-Advisory Agreement with UBS International Investment London Limited ('UBSII'
or  the 'Sub-Adviser' and,  together with the  Adviser, the 'Advisers'), whereby
the Sub-Adviser is primarily responsible for the day-to-day investment decisions
for the Portfolio. The Adviser is solely responsible for paying the  Sub-Adviser
for these services. The Sub-Adviser is an affiliate of the Adviser.
 
The  Advisers actively manage currency exposure, in conjunction with country and
stock allocations,  in  an attempt  to  protect the  Portfolio's  market  value.
Through  the  use  of  forward  foreign  currency  exchange  contracts,  futures
contracts and options on  currencies, the Advisers  will adjust the  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  the  Advisers'  experienced currency

The  Portfolio  intends to  manage  its securities  actively  in pursuit  of its
investment objective. The 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  Fund will be less than  100%. To the extent the
Portfolio engages  in short-term  trading, it  may incur  increased  transaction
costs.
 
EQUITY  INVESTMENTS. Under normal circumstances, the  Advisers intend to keep at
least 65% of the value of the  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  Portfolio's primary equity investments are  the common stock of established
companies based in developed countries outside the United States. The  Portfolio
will  invest in companies based  in at least five  foreign countries. The common
stock in which the 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 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 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  Portfolio may also  invest in money market  instruments denominated in U.S.
dollars and other currencies,  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'.
 
ADDITIONAL INVESTMENT INFORMATION AND RISK FACTORS
 
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.
 
CONVERTIBLE SECURITIES. The  convertible securities in  which the Portfolio  may
invest  include any  debt securities or  preferred stocks that  may be converted
into common stock or that carry the right to purchase common stock.  Convertible
securities  entitle the holder to exchange the securities for a specified number
of shares of  common stock,  usually of the  same company,  at specified  prices
within a certain period of time.
 
WHEN-ISSUED   AND  DELAYED  DELIVERY  SECURITIES.  The  Portfolio  may  purchase
securities on a when-issued or delayed  delivery basis. Delivery of and  payment
for  these securities may take as long as a  month or more after the date of the
purchase commitment.  The  value  of  these  securities  is  subject  to  market
fluctuation  during  this  period  and  no interest  or  income  accrues  to the
Portfolio until settlement. At  the time of  settlement, a when-issued  security
may  be valued at less than its purchase price. Between the trade and settlement
dates, the  Portfolio will  maintain  a segregated  account with  the  Custodian
consisting  of a portfolio of high-grade, liquid debt securities with a value at
least equal to these  commitments. When entering into  a when-issued or  delayed
delivery  transaction, the Portfolio will rely  on the other party to consummate
the transaction;  if the  other  party fails  to do  so,  the Portfolio  may  be
disadvantaged.  It is  the current  policy of  the Portfolio  not to  enter into
when-issued commitments exceeding in  the aggregate 15% of  the market value  of
the Portfolio's total assets less liabilities (excluding the obligations created
by these commitments).
 
REPURCHASE   AGREEMENTS.  The  Portfolio  may  engage  in  repurchase  agreement
transactions with  brokers, dealers  or banks  that meet  the credit  guidelines
approved  by the  Trust's Board  of Trustees  (the 'Trustees').  In a repurchase
agreement, the  Portfolio buys  a security  from  a seller  that has  agreed  to
repurchase  it at a mutually agreed upon date and price, reflecting the interest
rate effective for the term  of the agreement. The  term of these agreements  is
usually from overnight to one week. A repurchase
 
                                      -7-
 


<PAGE>
agreement may be viewed as a fully collateralized loan of money by the Portfolio
to  the seller.  The Portfolio always  receives securities as  collateral with a
market value at least equal to the purchase price plus accrued interest and this
value is maintained during the term of the agreement. If the seller defaults and
the collateral's value declines, the Portfolio might incur a loss. If bankruptcy
proceedings  are  commenced  with  respect   to  the  seller,  the   Portfolio's
realization  upon  the  disposition of  collateral  may be  delayed  or limited.
Investments in  repurchase  agreements maturing  in  more than  seven  days  and
certain  other  investments that  may be  considered  illiquid are  limited. See
'Illiquid Investments;  Privately  Placed  and  Other  Unregistered  Securities'
below.
 
REVERSE  REPURCHASE AGREEMENTS. The Portfolio is permitted to enter into reverse
repurchase agreements. In a reverse repurchase agreement, the Portfolio sells  a
security  and agrees to repurchase it at  a mutually agreed upon date and price,
reflecting the interest  rate effective for  the term of  the agreement. It  may
also  be viewed as the borrowing of money  by the Portfolio and, therefore, is a
form of leverage. Leverage may cause any gains or losses of the Portfolio to  be
magnified.  For more  information, including limitations  on the  use of reverse
repurchase agreements, see 'Investment Objectives  and Policies' in the SAI  and
'Investment Restrictions' below.
 
SECURITIES LENDING. Subject to applicable investment restrictions, the Portfolio
may lend its securities. The Portfolio may lend its securities if such loans are
secured  continuously by cash or equivalent collateral  or by a letter of credit
in favor of  the Portfolio at  least equal at  all times to  100% of the  market
value of the securities loaned, plus accrued interest. While such securities are
on  loan, the borrower will pay the Portfolio any income accruing thereon. Loans
will be subject to termination by  the Portfolio in the normal settlement  time,
generally  three business  days after  notice, or by  the borrower  on one day's
notice. Borrowed securities must  be returned when the  loan is terminated.  Any
gain  or loss in the market price  of the borrowed securities that occurs during
the term of the loan inures to  the Portfolio and its respective investors.  The
Portfolio  may pay reasonable  finders' and custodial fees  in connection with a
loan. In addition, the Portfolio will consider all the facts and  circumstances,
including  the creditworthiness of the  borrowing financial institution, and the
Portfolio will not make any loans in excess of one year. The Portfolio will  not
lend  its securities to any officer, Trustee, Director, employee or affiliate or
placement agent of the Portfolio, or the Adviser, Sub-Adviser, Administrator  or
Distributor, unless otherwise permitted by applicable law.
 
RISK  FACTORS  OF FOREIGN  SECURITIES. The  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  Portfolio's  investments  in
foreign  securities may be adversely affected  by changes in political or social
conditions,  diplomatic   relations,   confiscatory   taxation,   expropriation,
nationalization,  limitation on the removal of funds or assets, or imposition of
(or change in) exchange control or  tax regulations in those foreign  countries.
In  addition,  changes in  government  administrations or  economic  or monetary
policies in  the  United  States  or abroad  could  result  in  appreciation  or
depreciation  of portfolio securities and  could favorably or unfavorably affect
the Portfolio's  operations. Furthermore,  the economies  of individual  foreign
nations  may differ  from the U.S.  economy, favorably or  unfavorably, in areas
such  as  growth  of  gross   national  product,  rate  of  inflation,   capital
reinvestment, resource self-sufficiency and balance of payments position; it may
also  be  more difficult  to obtain  and  enforce a  judgment against  a foreign
issuer. Any foreign investments made by the Portfolio must be made in compliance
with U.S. and foreign currency restrictions and tax laws restricting the amounts
and types of 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 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
 
                                      -8-
 


<PAGE>
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 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 Portfolio's investment opportunities 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.
 
The Portfolio may  invest in securities  of foreign issuers  directly or in  the
form  of  American Depositary  Receipts  ('ADRs'), European  Depositary Receipts
('EDRs') 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.  Generally,
ADRs,  in registered form, are designed for  use in the U.S. securities markets,
and EDRs, in bearer form, are designed for use in European securities markets.
 
Because investments in foreign securities involve foreign currencies, the  value
of assets as measured in U.S. dollars may be affected, favorably or unfavorably,
by  changes  in currency  exchange rates  and  in exchange  control regulations,
including currency blockage. See 'Foreign Currency Exchange Transactions' below.
 
FOREIGN CURRENCY EXCHANGE TRANSACTIONS. Because the Portfolio will buy and  sell
securities  and will receive interest and dividends in currencies other than the
U.S. dollar, the Portfolio may, from  time to time, enter into foreign  currency
exchange transactions. The Portfolio may enter into these transactions on a spot
(i.e.,  cash) basis at the spot rate prevailing in the foreign currency exchange
market, use forward currency contracts  to purchase or sell foreign  currencies,
use  currency futures contracts or purchase  or sell options thereon or purchase
or sell currency options.
 
A forward foreign currency exchange contract  is an obligation of the  Portfolio
to purchase or sell a specific currency at a future date, which may be any fixed
number  of days from the  date of the contract.  Currency options give the buyer
the right, but  not the  obligation, to  purchase or sell  a fixed  amount of  a
specific currency at a fixed price at a future date. These contracts are entered
into  in the interbank  market directly between  currency traders (usually large
commercial banks)  and  their customers.  A  forward foreign  currency  exchange
contract  generally has  no deposit  requirement, and is  traded at  a net price
without commission. The  Portfolio will  not enter into  these foreign  currency
exchange  transactions  for  speculative  purposes.  Foreign  currency  exchange
transactions do not eliminate fluctuations in  the local currency prices of  the
Portfolio's  securities or  in foreign  exchange rates,  or prevent  loss if the
local currency prices of these securities should decline.
 
A currency futures contract is a contract involving an obligation to deliver  or
acquire  the specified amount of a currency  at a specified price at a specified
future time. Futures contracts may be settled on a net cash payment basis rather
than by the sale and delivery of the underlying currency.
 
The Portfolio  may  enter into  foreign  currency exchange  transactions  in  an
attempt  to protect against  changes in foreign  currency exchange rates between
the  trade  and  settlement  dates   of  specific  securities  transactions   or
anticipated  securities transactions. The Portfolio  may use these techniques to
hedge
 
                                      -9-
 


<PAGE>
against a change  in foreign currency  exchange rates (with  the U.S. dollar  or
other  foreign currencies) that would  cause a decline in  the value of existing
investments denominated or principally traded in a foreign currency.
 
Although these transactions are intended to minimize  the risk of loss due to  a
decline  in the value of the hedged  currency, these transactions also limit any
potential gain that might  be realized should the  value of the hedged  currency
increase.  Additionally,  the premiums  paid by  the  Portfolio for  currency or
futures options increase the Portfolio's transaction costs. Similarly, the  cost
of  the  Portfolio's  spot  currency  exchange  transactions  is  generally  the
difference between the bid and offer  spot rate of the currency being  purchased
or  sold. 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.
 
ILLIQUID  INVESTMENTS; PRIVATELY  PLACED AND OTHER  UNREGISTERED SECURITIES. The
Portfolio may not acquire any illiquid securities if, as a result thereof,  more
than  15% of the market value of the Portfolio's net assets would be in illiquid
investments or investments  that are  not readily marketable.  In addition,  the
Portfolio  will not invest more than 10% of the market value of its total assets
in restricted securities  (not including  Rule 144A securities)  that cannot  be
offered  for public  sale in  the United  States without  first being registered
under the Securities Act of 1933  (the 'Securities Act'). Subject to those  non-
fundamental  policy limitations, the Portfolio  may acquire investments that are
illiquid or have limited  liquidity, such as  private placements or  investments
that  are not  registered under  the Securities Act,  and cannot  be offered for
public sale in  the United States  without first being  registered. An  illiquid
investment is any investment that cannot be disposed of within seven days in the
normal  course of business at approximately the  amount at which it is valued by
the Portfolio.  Repurchase  agreements maturing  in  more than  seven  days  are
considered illiquid investments and, as such, are subject to the limitations set
forth in this paragraph. The price the Portfolio pays for illiquid securities or
receives  upon resale may be  lower than the price  paid or received for similar
securities with  a  more liquid  market.  Accordingly, the  valuation  of  these
securities will reflect any limitations on their liquidity.
 
The  Portfolio  may also  purchase Rule  144A  securities sold  to institutional
investors without registration under the Securities Act. These securities may be
determined to  be  liquid  in  accordance with  guidelines  established  by  the
Advisers  and approved by the  Trustees of the Trust.  The Trustees of the Trust
will monitor  the Advisers'  implementation of  these guidelines  on a  periodic
basis.
 
MONEY  MARKET INSTRUMENTS. The Portfolio is  permitted to invest in money market
instruments although it  intends to stay  invested in equity  securities to  the
extent   practical  in  light   of  its  objectives   and  long-term  investment
perspective. The  Portfolio  may make  money  market investments  pending  other
investments  or settlements, for liquidity or in adverse market conditions. Such
money market investments may include obligations of the U.S. Government and  its
agencies  and instrumentalities,  other debt securities,  commercial paper, bank
obligations and repurchase  agreements. The Portfolio  may purchase  nonpublicly
offered debt securities. The 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.
 
FUTURES  AND OPTIONS TRANSACTIONS. The Portfolio  is permitted to enter into the
futures and options transactions described below. These instruments are commonly
known as derivatives.
 
The Portfolio may purchase and sell exchange traded and over-the-counter ('OTC')
put and call options on equity securities or indices of equity securities, enter
into forward contracts, purchase and sell futures contracts on indices of equity
securities, purchase  and sell  put and  call options  on futures  contracts  on
indices  of equity securities  and purchase and sell  options on currencies. The
Portfolio may use these techniques for  hedging or risk management purposes  or,
subject to certain limitations, for investment
 
                                      -10-
 


<PAGE>
purposes  in  lieu  of investing  directly  in the  corresponding  securities or
instruments. Such use of derivatives may be considered speculative.
 
The Portfolio  may use  these  techniques to  manage  its exposure  to  changing
interest rates, currency exchange rates and/or security prices. Some options and
futures strategies, including selling futures contracts and buying puts, tend to
hedge  the Portfolio's investments against price fluctuations. Other strategies,
including buying futures contracts,  writing puts and  calls, and buying  calls,
may  tend to increase market  exposure. For example, if  the Portfolio wishes to
obtain exposure to a  particular market or  market sector but  does not wish  to
purchase  the  relevant  securities, it  could,  as an  alternative,  purchase a
futures contract on an  index of such securities  or related securities. Such  a
purchase  would not  constitute a  hedging transaction  and could  be considered
speculative. However, the  Portfolio will  use futures contracts  or options  in
this  manner only for the  purpose of obtaining the same  level of exposure to a
particular market or market sector that it could have obtained by purchasing the
relevant securities and will  not use futures contracts  or options to  leverage
its  exposure beyond this level. The use of options and futures may involve some
leverage; such leverage is reduced by the requirement of the SEC to 'cover' such
obligations. See  'Cover  -- Segregated  Accounts'  below. Options  and  futures
contracts  may be combined with each other or with forward contracts in order to
adjust the risk and return  characteristics of the Portfolio's overall  strategy
in  a  manner  deemed  appropriate  to  the  Advisers  and  consistent  with the
Portfolio's objective and policies. Because combined positions involve  multiple
trades,  they result in  higher transaction costs  and may be  more difficult to
open and close out.
 
The Portfolio's  use of  these transactions  is a  highly specialized  activity,
which  involves investment strategies and  risks different from those associated
with ordinary portfolio securities transactions,  and there can be no  guarantee
that  their use will increase the  Portfolio's return. While the Portfolio's use
of these  instruments  may  reduce  certain risks  associated  with  owning  its
portfolio securities, these techniques themselves entail certain other risks. If
the  Advisers  apply  a  strategy  at  an  inappropriate  time  or  judge market
conditions or  trends incorrectly,  such strategies  may lower  the  Portfolio's
return. Certain strategies limit the Portfolio's opportunity to realize gains as
well  as limiting its exposure to  losses. The Portfolio could experience losses
if the prices of its options  and futures positions were poorly correlated  with
its  other investments, or if it could not close out its positions because of an
illiquid  secondary  market.  In  addition,  the  Portfolio  will  incur  costs,
including  commissions and premiums,  in connection with  these transactions and
these transactions could significantly increase the Portfolio's turnover rate.
 
The Portfolio  may  purchase  and  sell put  and  call  options  on  securities,
currencies,  indices of securities  and futures contracts,  or purchase and sell
futures contracts for the purposes described herein.
 
The Commodity Exchange Act prohibits U.S.  persons, such as the Portfolio,  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  Portfolio will not  be considered  a
'commodity  pool'  for purposes  of CFTC  rules, the  Portfolio will  enter into
transactions in futures contracts  or options on futures  contracts only if  (1)
such  transactions constitute bona  fide hedging transactions,  as defined under
CFTC rules, or (2) no more than  5% of the Portfolio's net assets are  committed
as  initial margin  or premiums  to positions that  do not  constitute bona fide
hedging transactions.
 
OPTIONS
 
PURCHASING PUT  AND CALL  OPTIONS. By  purchasing a  put option,  the  Portfolio
obtains the right (but not the obligation) to sell the instrument underlying the
option at a fixed strike price. In return for this right, the Portfolio pays the
current  market price for the option (known as the option premium). Options have
various  types  of  underlying   instruments,  including  specific   securities,
currencies,  indices of  securities, indices  of securities  prices, and futures
contracts. The  Portfolio may  terminate its  position in  a put  option it  has
purchased  by allowing it to  expire or by exercising  the option. The Portfolio
may also  close  out  a put  option  position  by entering  into  an  offsetting
transaction,  if a liquid market exists. If the option is allowed to expire, the
Portfolio will lose  the entire premium  it paid. If  the Portfolio exercises  a
 
                                      -11-
 


<PAGE>
put  option on a security, it will  sell the instrument underlying the option at
the strike price. If the Portfolio  exercises an option on an index,  settlement
is  in cash and does  not involve the actual  sale of securities. American style
options may be exercised on any day up to their expiration date. European  style
options may be exercised only on their expiration date.
 
The  buyer of a typical put option can expect  to realize a gain if the price of
the underlying  instrument falls  substantially. However,  if the  price of  the
instrument  underlying the  option does  not fall enough  to offset  the cost of
purchasing the option, a put buyer can  expect to suffer a loss (limited to  the
amount of the premium paid, plus related transaction costs).
 
The  features of call options are essentially  the same as those of put options,
except that the purchaser of a call option obtains the right to purchase, rather
than sell, the instrument underlying the option at the option's strike price.  A
call buyer typically attempts to participate in potential price increases of the
instrument underlying the option with risk limited to the cost of the option and
related  transaction costs if security prices fall.  At the same time, the buyer
can expect to  suffer a  loss if  security prices  do not  rise sufficiently  to
offset the cost of the option.
 
SELLING  (WRITING) PUT AND CALL OPTIONS. When the Portfolio writes a put option,
it takes the opposite  side of the transaction  from the option's purchaser.  In
return  for receipt of the premium, the  Portfolio assumes the obligation to pay
the strike price for the instrument underlying the option if the other party  to
the  option chooses  to exercise  it. The  Portfolio may  seek to  terminate its
position in a put option it  writes before exercise by purchasing an  offsetting
option in the market at its current price. If the market is not liquid for a put
option  the Portfolio  has written, however,  the Portfolio must  continue to be
prepared to pay the strike price while the option is outstanding, regardless  of
price changes, and must continue to post margin as discussed below.
 
If  the price of the  underlying instrument rises, a  put writer would generally
expect to  profit, although  its gain  would be  limited to  the amount  of  the
premium  it received. If security prices remain the same over time, it is likely
that the writer will  also profit, because  it should be able  to close out  the
option  at a lower price. If security prices fall, however, the put writer would
expect to suffer a loss. This loss should be less than the loss from  purchasing
and  holding the  underlying instrument  directly, however,  because the premium
received for writing the option should offset a portion of the decline.
 
Writing a call option  obligates the Portfolio to  sell or deliver the  option's
underlying  instrument  in return  for  the strike  price  upon exercise  of the
option. The characteristics  of writing  call options  are similar  to those  of
writing  put  options,  except  that writing  calls  generally  is  a profitable
strategy if  prices remain  the same  or  fall. Through  receipt of  the  option
premium  a call writer  offsets part of the  effect of a  price decrease. At the
same time, because  a call  writer must be  prepared to  deliver the  underlying
instrument in return for the strike price, even if its current value is greater,
a call writer gives up some ability to participate in security price increases.
 
The  writer of a U.S. exchange traded put or call option on a security, an index
of securities or a futures contract is required to deposit cash or securities or
a letter of credit  as margin and to  make mark-to-market payments of  variation
margin if and as the position becomes unprofitable.
 
OPTIONS   ON  INDICES.  The  Portfolio  is   permitted  to  enter  into  options
transactions and may purchase  and sell put and  call options on any  securities
index  based  on  securities  in  which the  Portfolio  may  invest.  Options on
securities indices  are  similar  to  options on  securities,  except  that  the
exercise  of securities index  options is settled  by cash payment  and does not
involve the actual purchase  or sale of securities.  In addition, these  options
are  designed to reflect price fluctuations in  a group of securities or segment
of the securities market  rather than price fluctuations  in a single  security.
The  Portfolio, in purchasing or  selling index options, is  subject to the risk
that the value of its  portfolio securities may not change  as much as an  index
because  the Portfolio's investments generally will not match the composition of
an index.
 
For a number of reasons,  a liquid market may not  exist and thus the  Portfolio
may  not be able to close out an  option position that it has previously entered
into. When the  Portfolio purchases an  OTC option,  it will be  relying on  its
counterparty  to perform its obligations, and the Portfolio may incur additional
losses if the counterparty is unable to perform.
 
                                      -12-
 


<PAGE>
FUTURES CONTRACTS
 
When the  Portfolio  purchases a  futures  contract,  it agrees  to  purchase  a
specified  quantity of an  underlying instrument at a  specified future date and
price or to make or  receive a cash payment based  on the value of a  securities
index.  When  the  Portfolio sells  a  futures  contract, it  agrees  to  sell a
specified quantity of the underlying instrument  at a specified future date  and
price  or to receive or make  a cash payment based on  the value of a securities
index. The price at which  the purchase and sale will  take place is fixed  when
the Portfolio enters into the contract. Futures can be held until their delivery
dates  or the positions can be (and  normally are) closed out before then. There
is no  assurance, however,  that a  liquid market  will exist  when a  Portfolio
wishes to close out a particular position.
 
When  the Portfolio  purchases or  sells a  futures contract,  the value  of the
futures contract tends to increase and decrease in tandem with the value of  its
underlying  instrument. Purchasing  futures contracts  may tend  to increase the
Portfolio's  exposure  to  positive  and  negative  price  fluctuations  in  the
underlying  instrument, much  as if it  had purchased  the underlying instrument
directly, as discussed above.  When the Portfolio sells  a futures contract,  by
contrast,  the value of  its futures position  will tend to  move in a direction
contrary to the value of the underlying instrument. Selling futures contracts on
securities similar  to those  held by  the Portfolio,  therefore, will  tend  to
offset  both  positive  and  negative  market  price  changes,  much  as  if the
underlying instrument had been sold. Because there are a limited number of types
of exchange-traded  options  and futures  contracts,  it is  likely  that  these
standardized  instruments  will not  exactly  match the  Portfolio's  current or
anticipated investments.  The  Portfolio may  invest  in futures  contracts  and
options  thereon based  on currencies or  on securities  with different issuers,
maturities, or other characteristics from  the securities in which it  typically
invests,  which involves a  risk that the  options or futures  position will not
track the performance of  the Portfolio's other  investments. The Portfolio  may
also  enter into transactions  in futures contracts  and options for non-hedging
purposes, as discussed above.
 
The purchaser or seller of a futures contract is not required to deliver or  pay
for  the underlying  instrument unless the  contract is held  until the delivery
date. However, when the Portfolio  buys or sells a  futures contract it will  be
required  to deposit 'initial margin' with the Custodian in a segregated account
in the  name of  its futures  broker,  known as  a futures  commission  merchant
('FCM').  Initial margin deposits  are typically equal to  a small percentage of
the contract's value.  If the value  of either party's  position declines,  that
party  will be required to make  additional 'variation margin' payments equal to
the change in value on a daily basis. The party that has a gain may be  entitled
to  receive all or a  portion of this amount. The  Portfolio may be obligated to
make payments of variation margin at a time when it is disadvantageous to do so.
Furthermore, it may not always  be possible for the  Portfolio to close out  its
futures positions. Until it closes out a futures position, the Portfolio will be
obligated  to continue  to pay  variation margin.  Initial and  variation margin
payments do not constitute purchasing on margin for purposes of the  Portfolio's
investment  restrictions. In the  event of the  bankruptcy of an  FCM that holds
margin on behalf of the  Portfolio, the Portfolio may  be entitled to return  of
margin  owed to it only in proportion to  the amount received by the FCM's other
customers, potentially resulting in losses to the Portfolio.
 
COVER -- SEGREGATED  ACCOUNTS. The Portfolio  will segregate liquid,  high-grade
debt  securities in connection with its use  of options and futures contracts to
the extent required by the SEC.  Securities held in a segregated account  cannot
be  sold while the  futures contract or  option is outstanding,  unless they are
replaced with other suitable  assets. As a result,  there is a possibility  that
the  segregation of  a large percentage  of the Portfolio's  assets could impede
portfolio management or the Portfolio's  ability to meet redemption requests  or
other current obligations.
 
For  further information about the Portfolio's use  of futures and options and a
more detailed discussion  of associated  risks, see  'Investment Objectives  and
Policies' in the SAI.
 
INVESTMENT RESTRICTIONS
 
The  investment  objective of  the  Fund and  the  Portfolio, together  with the
investment restrictions described  below and in  the SAI, except  as noted,  are
deemed  fundamental policies, i.e., they  may be changed only  by the 'vote of a
majority  of   the   outstanding  voting   securities'   (as  defined   in   the
 
                                      -13-
 


<PAGE>
Investment  Company Act of 1940 (the '1940 Act')), of the Fund or the Portfolio,
respectively. The Fund has  the same investment  restrictions as the  Portfolio,
except that the Fund may invest all of its investable assets in another open-end
investment  company with the same investment objective and restrictions (such as
the Portfolio). References below to the Portfolio's investment restrictions also
include the Fund's investment restrictions.
 
As a diversified investment  company, 75% of the  total assets of the  Portfolio
are  subject to the following fundamental limitations: (a) the Portfolio may not
invest more than 5%  of its total  assets in the securities  of any one  issuer,
except  U.S. Government securities; and (b) the  Portfolio may not own more than
10% of the outstanding voting securities of any one issuer.
 
The Portfolio  may not:  (i) purchase  the securities  or other  obligations  of
issuers conducting their principal business activity in the same industry if its
investments  in such industry would  exceed 25% of the  value of the Portfolio's
total assets, except  this limitation  shall not  apply to  investments in  U.S.
Government  securities; (ii) enter  into reverse repurchase  agreements or other
permitted borrowings  that  constitute senior  securities  under the  1940  Act,
exceeding  in  the aggregate  one-third of  the value  of the  Portfolio's total
assets; or (iii) borrow money, except from banks for extraordinary or  emergency
purposes,  or mortgage,  pledge or hypothecate  any assets  except in connection
with any such borrowings or  permitted reverse repurchase agreements in  amounts
up to one-third of the value of the Portfolio's total assets at the time of such
borrowing,  or purchase securities while  borrowings and other senior securities
exceed 5% of  its total  assets. For  a more  detailed discussion  of the  above
investment  restrictions, as well  as a description  of certain other investment
restrictions, see 'Investment Restrictions' in the SAI.
 
MANAGEMENT
 
DIRECTORS AND  TRUSTEES.  Pursuant to  the  Trust's Declaration  of  Trust,  the
Trustees   of  the  Trust  establish   the  Portfolio's  general  policies,  are
responsible for the overall management of  the Trust, and review the actions  of
the  Adviser, Sub-Adviser, Administrator and other service providers. Similarly,
the Directors of the Company set the Company's general policies, are responsible
for the overall  management of the  Company, and review  the performance of  its
service providers. Additional information about the Company's Board of Directors
and  officers appears in the SAI under the heading 'Directors and Trustees'. The
Trustees of  the Trust  are also  the  Directors of  the Company,  which  raises
certain  conflicts  of interest.  The Company  and the  Trust have  each adopted
written procedures reasonably designed to deal with these conflicts, should they
arise. The  officers of  the Company  are  also employees  of Signature  or  its
affiliates.
 
ADVISER  AND FUNDS SERVICES AGENT. The Company  has not retained the services of
an investment adviser with respect to the Fund because the Fund seeks to achieve
its investment  objective by  investing  all of  its  investable assets  in  the
Portfolio.  The Portfolio has retained the  services of the Branch as investment
adviser and UBSII 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. 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 (including UBSII)  engages in a  wide
range  of  banking  and  financial  activities  typical  of  the  world's  major
international banks,  including  fiduciary, investment  advisory  and  custodial
services   and  foreign  exchange  in  the   United  States,  Swiss,  Asian  and
Euro-capital markets. The Bank is one of the world's leading asset managers  and
has  been active  in New York  City since 1946.  At December 31,  1996, the Bank
(including its consolidated subsidiaries) had total assets of $326.7 billion and
equity capital and  reserves of  $17.1 billion.  The Branch  has not  previously
advised  a mutual fund, but has considerable experience managing portfolios with
similar investment objectives. This  could be viewed as  a risk of investing  in
this Fund.
    
 
                                      -14-
 


<PAGE>
The   Advisers  provide  investment  advice  and  portfolio  management  to  the
Portfolio. Subject  to the  supervision of  the Trustees  and the  Adviser,  the
Sub-Adviser  makes the Portfolio's day-to-day investment decisions, arranges for
the execution of  portfolio transactions and  generally manages the  Portfolio's
investments and operations. See 'Investment Adviser and Funds Services Agent' in
the SAI.
 
In  addition to the  above-listed investment advisory  services, the Branch also
provides  the  Fund  and  the  Portfolio  with  certain  related  administrative
services.   Subject  to   the  supervision   of  the   Directors  and  Trustees,
respectively, the Branch is responsible for: establishing performance  standards
for  the third-party service providers of  the Fund and Portfolio and overseeing
and evaluating  the  performance  of such  entities;  providing  and  presenting
quarterly  management reports to the Directors and the Trustees; supervising the
preparation of reports  for Fund  and Portfolio  shareholders; and  establishing
voluntary  expense limitations for the Fund  and providing any resultant expense
reimbursement to the Fund.
 
The Branch provides its administrative services to the Fund pursuant to a  Funds
Services  Agreement  between the  Branch and  the Company.  The Branch  does not
receive a fee from the  Company or the Fund pursuant  to the terms of the  Funds
Services Agreement.
 
   
Under  the Trust's Investment Advisory Agreement, the Portfolio pays the Adviser
a fee, calculated daily and payable monthly, equal, on an annual basis, to 0.85%
of the Portfolio's average daily net  assets. The Branch has voluntarily  agreed
to  waive its  fees and reimburse  the Fund for  any of its  direct and indirect
expenses to the extent that the  Fund's total operating expenses (including  its
share  of the  Portfolio's expenses)  exceed, on an  annual basis,  0.95% of the
Fund's average daily net assets. The  Branch may modify or discontinue this  fee
waiver  and expense  limitation at any  time in  the future with  30 days' prior
notice to the Fund. See 'Expenses'.
    
 
SUB-ADVISER. The Sub-Adviser  uses a  sophisticated, disciplined,  collaborative
process  for managing all asset classes. Robin Apps is primarily responsible for
the day-to-day management  and implementation of  the Sub-Adviser's process  for
the  Portfolio. Mr.  Apps has  been a Senior  Vice President  of the Sub-Adviser
since 1990, and is responsible  for researching investment opportunities in  the
Far  East. Mr. Apps has previously managed  the investments of a Canadian mutual
fund. Mr. Apps received  a bachelors degree from  Birmingham University and  has
twelve years of investment experience. Mr. Apps is also qualified as an actuary.
 
Pursuant  to the Sub-Advisory Agreement between the Adviser and the Sub-Adviser,
the Adviser  has agreed  to pay  the  Sub-Adviser a  fee, calculated  daily  and
payable  monthly, equal, on an  annual basis, to 0.75%  of the Portfolio's first
$20 million average daily net assets, and 0.50% of the next $30 million  average
daily  net assets,  plus 0.40%  of the Portfolio's  average daily  net assets in
excess of  $50  million.  The  Adviser is  solely  responsible  for  paying  the
Sub-Adviser this fee.
 
INVESTMENTS  IN THE FUND ARE NOT DEPOSITS  WITH OR OBLIGATIONS OF, OR GUARANTEED
OR ENDORSED BY, THE BRANCH OR ANY OTHER BANK.
 
ADMINISTRATORS. Under Administrative Service Agreements with the Company and the
Trust, Signature and Signature-Cayman  serve as the  Administrators of the  Fund
and  the Portfolio, respectively (in  such capacities, the 'Administrators'). In
these capacities, Signature and Signature-Cayman  administer all aspects of  the
Fund's  and the Portfolio's day-to-day operations, subject to the supervision of
the Adviser and the  Directors and Trustees, respectively,  except as set  forth
under  'Adviser  and  Funds  Services  Agent',  'Distributor',  'Custodian'  and
'Shareholder  Services'.  The   Administrators:  (i)   furnish  general   office
facilities  and ordinary clerical and related services for day-to-day operations
including  recordkeeping   responsibilities;   (ii)  take   responsibility   for
compliance with all applicable federal and state securities and other regulatory
requirements;  and (iii) perform administrative  and managerial oversight of the
activities of  the custodian,  transfer agent  and other  agents or  independent
contractors  of the  Fund and the  Portfolio. Signature is  also responsible for
monitoring the  Fund's  status  as  a regulated  investment  company  under  the
Internal Revenue Code of 1986, as amended (the 'Code').
 
Under  the Company's Administrative  Services Agreement, the  Fund has agreed to
pay Signature a fee, calculated daily  and payable monthly, equal, on an  annual
basis,  to 0.05% of the  Fund's first $100 million  average daily net assets and
0.025% of the  next $100 million  average daily net  assets. Signature does  not
receive  a fee  from the  Fund on  average daily  net assets  in excess  of $200
million.
 
                                      -15-
 


<PAGE>
Under the Trust's Administrative Services Agreement, the Portfolio has agreed to
pay Signature-Cayman a fee, calculated daily  and payable monthly, equal, on  an
annual basis, to 0.05% of the Portfolio's average daily net assets.
 
DISTRIBUTOR. Under the Distribution Agreement, Signature, located at 6 St. James
Avenue,  Boston, MA  02116, serves  as the distributor  of Fund  shares (in such
capacity,  the  'Distributor').  The   Distributor  is  a  wholly-owned   direct
subsidiary of Signature Financial Group, Inc. and is a registered broker-dealer.
The Distributor does not receive a fee pursuant to the terms of the Distribution
Agreement.
 
CUSTODIAN.  Investors Bank & Trust Company,  whose principal offices are located
at 89 South Street, Boston, Massachusetts 02111, serves as the custodian for the
Portfolio and the Fund and transfer and dividend disbursing agent for the  Fund.
See  'Custodian' in  the SAI.  The Custodian also  maintains offices  at 1 First
Canadian Place, Suite 2800, Toronto, Ontario M5X1C8.
 
SHAREHOLDER SERVICES
 
The Company has entered into a shareholder servicing agreement with the  Branch,
and  may enter into additional shareholder servicing agreements with one or more
financial institutions (together with the Branch, 'Eligible Institutions')  such
as   a  federal  or  state-chartered  bank,  trust  company,  savings  and  loan
association or  savings bank,  or broker-dealer.  Pursuant to  each  shareholder
servicing agreement, an Eligible Institution, as agent for its customers who are
purchasing  shares of  the Fund, will  perform the following  services for these
investors, among other  things: coordinating shareholder  accounts and  records,
assisting  investors  seeking  to  purchase  or  redeem  Fund  shares, providing
performance information  relating to  the Fund,  and responding  to  shareholder
inquiries.  The Company has  agreed to pay  each Eligible Institution  a fee for
these services equal,  on an annual  basis, to  0.25% of the  average daily  net
assets of the Fund represented by shares of the Fund owned during the period for
which  payment is being made by customers of the Eligible Institution. Under the
terms  of  the  shareholder  servicing  agreements,  Eligible  Institutions  may
delegate  one  or more  of  their responsibilities  to  other entities  at their
expense.
 
EXPENSES
 
   
In addition  to  the  fees  of  the  Branch,  Signature-Cayman,  Signature,  and
Investors Bank & Trust Company, the Fund will be responsible for other expenses,
including  brokerage costs and litigation and extraordinary expenses. The Branch
has voluntarily  agreed  to limit  the  total  operating expenses  of  the  Fund
(including  its  share  of the  Portfolio's  expenses),  excluding extraordinary
expenses, to an annual rate not to exceed 0.95% of the Fund's average daily  net
assets.  The Branch may modify or  discontinue this voluntary expense limitation
at any time in the future with 30 days' prior notice to the Fund.
    
 
The Fund  and  the  Portfolio  may  allocate  brokerage  transactions  to  their
affiliates and the Advisers' 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 Fund may be purchased only in those states where
they may be lawfully sold.
 
The business days of the Fund and the Portfolio are the days the New York  Stock
Exchange (the 'NYSE') is open for regular trading.
 
The  shares of the Fund are sold on a continuous basis without a sales charge at
the net asset value per share next determined after receipt and acceptance of  a
purchase  order by the Distributor.  The Fund calculates its  net asset value at
the close of business. See 'Net Asset Value'. The minimum initial investment  in
the  Fund is $25,000, except that the  minimum initial investment is $10,000 for
shareholders of another series of the Company. The minimum subsequent investment
in the Fund  for all  investors is $5,000.  The minimum  initial investment  for
employees of the Bank or its affiliates is $5,000.
 
                                      -16-
 


<PAGE>
The  minimum  subsequent  investment  is $1,000.  For  purposes  of  the minimum
investment  requirements,  the  Fund   may  aggregate  investments  by   related
shareholders.  These minimum investment requirements may be waived at the Fund's
discretion. 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
investor's subscription is accepted. See 'Purchase of Shares' in the SAI.
 
Purchase  orders in proper form  received by the Distributor  prior to 4:00 p.m.
New York time or the close of regular trading on the NYSE, whichever is earlier,
are effective and  executed at  the net asset  value next  determined that  day.
Purchase orders received after 4:00 p.m. New York time or the close of the NYSE,
whichever  is earlier, will be executed at the net asset value determined on the
next business day. Investors become record  shareholders of the Fund on the  day
they  place their subscription order, provided it is received by the Distributor
before 4:00  p.m.  As  record  shareholders,  investors  are  entitled  to  earn
dividends.  Settlement date  for purchases  is the  next business  day following
trade date.
 
Customers of  Eligible Institutions  should request  a representative  of  their
Eligible  Institution  to  assist them  in  placing  a purchase  order  with the
Distributor. Shareholders who do not  currently maintain a relationship with  an
Eligible  Institution  may  purchase  shares  of  the  Fund  directly  from  the
Distributor by wire transfer or mail.
 
The Transfer Agent will maintain the accounts for all shareholders who  purchase
Fund  shares directly through  the Distributor. For  account balance information
and shareholder services, such shareholders should contact the Transfer Agent at
(888) UBS-FUND or in writing at UBS Private Investor Funds, Inc., c/o  Investors
Bank and Trust Company, P.O. Box 1537 MFD 23, Boston, MA 02205-1537.
 
By  wire: Purchases may be made by federal funds wire. To place a purchase order
with the  Fund, the  shareholder  must telephone  the  Transfer Agent  at  (888)
UBS-FUND for specific instructions.
 
Subject  to the minimum purchase  requirements discussed above, shares purchased
by federal funds wire  will be effected  at the net asset  value per share  next
determined after acceptance of the order.
 
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 shareholder's  account number
must be clearly marked on the check to ensure proper credit.
 
By  mail:  Subject  to  the  minimum  purchase  requirements  discussed   above,
shareholders  may  purchase  shares  of  the  Fund  through  the  Distributor by
completing an account application and mailing it, together with a check  payable
to 'UBS Private Investor Funds, Inc.', to: UBS Private Investor Funds, Inc., c/o
Investors Bank & Trust Company, P.O. Box 1537 MFD 23, Boston, MA 02205-1537.
 
Checks  are subject to collection at full  value. For shares purchased by check,
dividend payments and redemption  proceeds, if any, will  be delayed until  such
funds are collected, which may take up to 15 days from the date of purchase.
 
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. The Fund calculates its net  asset value at the close of  business.
See 'Net Asset Value'.
 
A  redemption order will  be effected provided the  Distributor receives such an
order prior to 4:00 p.m.  New York time or the  close of regular trading on  the
NYSE,  whichever is earlier. The  redemption of Fund shares  is effective and is
executed at the  net asset  value next  determined that  day. Redemption  orders
received  after 4:00 p.m. New  York time or the close  of regular trading on the
NYSE, whichever is earlier, will be  executed at the net asset value  determined
on  the next  business day.  Proceeds of  an effective  redemption are generally
deposited the next business  day in immediately available  funds to the  account
designated  by the redeeming shareholder or  mailed to the shareholder's address
of record, in accordance with the shareholder's instructions.
 
                                      -17-
 


<PAGE>
Shareholders will not  be recordholders for  dividend purposes on  the day  that
they redeem Fund shares.
 
Customers  of  Eligible  Institutions  must request  a  representative  of their
Eligible Institution to assist them in placing a redemption order.  Shareholders
whose  accounts are maintained by  the Transfer Agent may  redeem Fund shares by
telephone or mail.
 
By telephone: Telephone redemptions may be made by calling the Transfer Agent at
(888) UBS-FUND. Redemption orders will be accepted until 4:00 p.m. New York time
or the close  of regular trading  on the NYSE,  whichever is earlier.  Telephone
redemption  requests  are  limited  to those  shareholders  who  have previously
elected this  service. Such  shareholders risk  possible loss  of principal  and
income  in the event of a telephone  redemption not authorized by them. The Fund
and the  Transfer  Agent  will  employ  reasonable  procedures  to  verify  that
telephone redemption instructions are genuine and will require that shareholders
electing  such an option provide a  form of personal identification. The failure
by the Fund or the Transfer Agent  to employ such procedures may cause the  Fund
or  the Transfer Agent to be liable for  any losses incurred by investors due to
telephone redemptions based  upon unauthorized or  fraudulent instructions.  The
telephone  redemption option may be modified or discontinued at any time upon 60
days' notice to shareholders.
 
By mail:  Redemption  requests  may  also  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, 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.
The  redemption request in  proper form should  be sent to  UBS Private Investor
Funds, Inc., c/o Investors Bank and Trust Company, P.O. Box 1537 MFD 23, Boston,
MA 02205-1537.
 
MANDATORY REDEMPTION. If the value of a shareholder's holdings in the Fund falls
below $10,000 because  of a  redemption of shares,  the shareholder's  remaining
shares  may  be redeemed  60 days  after  written notice  unless the  account is
increased to $10,000 or more. For example, a shareholder whose initial and  only
investment  is $10,000 may be subject to mandatory redemption resulting from any
redemption that causes his or her investment to fall below $10,000.
 
FURTHER REDEMPTION INFORMATION. Investors should  be aware that redemptions  may
not  be processed unless the redemption request  is submitted in proper form. To
be in  proper form,  the  Fund must  have  received the  shareholder's  taxpayer
identification  number and address.  As discussed under  'Taxes' below, the Fund
may be  required  to impose  'back-up'  withholding  of federal  income  tax  on
dividends,  distributions and redemptions when  non-corporate investors have not
provided a certified taxpayer identification number. In addition, if an investor
sends a check to the Distributor for the purchase of Fund shares and shares  are
purchased  with funds  made available  by the  Distributor before  the check has
cleared, the transmittal of  redemption proceeds from the  sale of those  shares
will  not occur until the check used  to purchase such shares has cleared, which
may take up to 15 days. Redemption delays may be avoided by purchasing shares by
federal funds wire.
 
The right of redemption may  be suspended or the  date of payment postponed  for
such  periods as the 1940 Act or the  SEC may permit. See 'Redemption of Shares'
in the SAI.
 
EXCHANGE OF SHARES
 
An investor may  exchange Fund  shares for  shares of  any other  series of  the
Company,  without charge. An exchange may be  made so long as after the exchange
the investor has shares, in each series in which it remains an investor, with  a
value  equal to or greater than each such series' minimum investment amount. See
'Purchase of Shares'  in the prospectuses  of the other  Company series for  the
minimum  investment amounts for each of those funds. Shares are exchanged on the
basis of relative net asset value per share.
 
                                      -18-
 


<PAGE>
Exchanges are in effect redemptions from one fund and purchases of another  fund
and the usual purchase and redemption procedures and requirements are applicable
to exchanges. See appropriate section relating to the purchase and redemption of
shares  in this and other prospectuses.  See also 'Additional Information' below
for an explanation of the telephone exchange policy.
 
Shareholders subject to federal income tax  who exchange shares in one fund  for
shares in another fund may recognize capital gain or loss for federal income tax
purposes.  The  Fund  reserves the  right  to  discontinue, alter  or  limit its
exchange  privilege  at  any  time.  For  investors  in  certain  states,  state
securities laws may restrict the availability of the exchange privilege.
 
RETIREMENT PLANS
 
The  Fund  has available  a form  of Individual  Retirement Account  ('IRA') for
investment in Fund shares. Subject to certain restrictions imposed by applicable
tax laws,  self-employed individuals  may purchase  shares of  the Fund  through
tax-deductible contributions to existing retirement plans known as Self-Employed
Retirement  Plans ('SERPs'). Fund  shares may also be  a suitable investment for
'401(k) Plans' which subject to certain restrictions allow their participants to
invest in qualified  pension plans on  a tax-deferred basis.  The Fund does  not
currently act as sponsor to such plans.
 
The  minimum initial  investment for  all such  retirement plans  is $2,000. The
minimum for all subsequent investments is $500.
 
Under the 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  $2,250 annually to one or both
IRAs provided that no more than $2,000  may be contributed to the IRA of  either
spouse.
 
Investors  should be aware that  they may be subject  to penalties or additional
taxes on contributions  to or withdrawals  from IRAs or  other retirement  plans
under certain circumstances. Prior to a withdrawal, shareholders may be required
to  certify  as to  their age  and  awareness of  such restrictions  in writing.
Clients of  Eligible Institutions  desiring information  concerning  investments
through   IRAs  or  other   retirement  plans  should   contact  their  Eligible
Institution. Clients  who  do  not  maintain a  relationship  with  an  Eligible
Institution  may obtain such information by  calling the Transfer Agent at (888)
UBS-FUND.
 
DIVIDENDS AND DISTRIBUTIONS
 
Dividends consisting of substantially all  of the Fund's net investment  income,
if  any, are declared and paid annually. The Fund may also declare an additional
dividend of net investment  income in a  given year to  the extent necessary  to
avoid the imposition of federal excise taxes on the Fund.
 
Substantially  all of  the Fund's  realized net capital  gains, if  any, will be
declared and paid on  an annual basis, except  that an additional capital  gains
distribution  may be made in  a given year to the  extent necessary to avoid the
imposition  of  federal  excise  taxes  on  the  Fund.  Declared  dividends  and
distributions  are payable on the payment date  to shareholders of record on the
record date.
 
Dividends and capital  gains distributions  paid by the  Fund are  automatically
reinvested  in additional  Fund shares  unless the  shareholder has  elected, in
writing, to have them paid  in cash. Dividends and  distributions to be paid  in
cash  are credited to the account designated by the shareholder or sent by check
to the shareholder's  address of  record, in accordance  with the  shareholder's
instructions.  The Fund  reserves the right  to discontinue, alter  or limit the
automatic reinvestment privilege at any time.
 
NET ASSET VALUE
 
The Fund's net asset value per share equals the value of the Fund's total assets
(i.e., the value of its investment in the Portfolio plus its other assets)  less
the  amount of its liabilities, divided by the number of its outstanding shares,
rounded to the nearest cent. Expenses, including the fees payable to the service
providers of the Fund and the Portfolio, are accrued daily. Securities for which
market quotations are
 
                                      -19-
 


<PAGE>
readily available  are valued  at market  value. All  other securities  will  be
valued  at 'fair value.' See 'Net Asset Value' in the SAI for information on the
valuation of the Portfolio's assets and liabilities.
 
The Fund computes its  net asset value  once daily at the  close of business  on
Monday  through Friday, except that the net  asset value is not computed for the
Fund on a day  in which no orders  to purchase or redeem  Fund shares have  been
received  or on  any day on  which the  NYSE is closed,  including the following
holidays:  New  Year's  Day,  Presidents'   Day,  Good  Friday,  Memorial   Day,
Independence  Day, Labor Day,  Thanksgiving Day and Christmas  Day. On days when
U.S. trading  markets close  early in  observance of  these holidays,  the  Fund
expects to close for purchases and redemptions at the same time.
 
Many  of  the  securities  held  by the  Portfolio  will  consist  of securities
primarily listed on foreign  exchanges, and these securities  may trade on  days
when  the Fund's net asset  value is not calculated.  Consequently, the value of
these securities may be significantly affected on days when an investor will  be
unable to redeem its shares.
 
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  four series: The  UBS Bond Fund Series;  The UBS Tax  Exempt
Bond  Fund Series; The  UBS International Equity  Fund Series; and  The UBS U.S.
Equity Fund Series. Each outstanding share of  the Company will have a pro  rata
interest in the assets of its series, but it will have no interest in the assets
of any other Company series. Only shares of UBS International Equity Fund Series
are offered through this Prospectus.
 
Shareholder  inquiries by clients of Eligible Institutions should be directed to
their Eligible  Institution,  while  other  shareholders  should  address  their
inquiries to the Transfer Agent.
 
Shareholders  of the  Fund are entitled  to one vote  for each share  and to the
appropriate fractional vote for  each fractional share.  There is no  cumulative
voting.  Shares have no  preemptive or conversion rights.  Shares are fully paid
and nonassessable when  issued by the  Company. The Company  does not intend  to
hold  meetings  of shareholders  annually. The  Directors  may call  meetings of
shareholders for action by shareholder vote  as may be required by its  Articles
of  Incorporation  or  the  1940 Act.  For  further  organizational information,
including certain shareholder rights, see 'Organization' in the SAI.
 
UBS INVESTOR PORTFOLIOS TRUST
 
UBS Investor Portfolios Trust,  a master trust fund  formed under New York  law,
was organized on February 9, 1996. The Declaration of Trust permits the Trustees
to  issue interests divided into one or more subtrusts or series. To date, three
series have been authorized, of which UBS International Equity Portfolio is one.
 
The Declaration  of  Trust  provides  that  no  Trustee,  shareholder,  officer,
employee,  or agent of  the Trust shall  be held to  any personal liability, nor
shall resort be had  to such person's private  property for the satisfaction  of
any  obligation or  claim or  otherwise in  connection with  the affairs  of the
Portfolio, but that only the Trust property shall be liable.
 
The Declaration of Trust provides that the Fund and other entities investing  in
the  Portfolio  (e.g., other  investment  companies, insurance  company separate
accounts and common and commingled trust funds) will each be liable for all  the
obligations  of  the  Portfolio.  However,  the  risk  of  the  Fund's incurring
financial loss on account of such liability is limited to circumstances in which
both inadequate insurance existed  and the Portfolio itself  was unable to  meet
its obligations. Accordingly, the Trustees believe that neither the Fund nor its
shareholders  will be adversely  affected by reason of  the Fund's investment in
the Portfolio.
 
TAXES
 
Each Fund  has  qualified  and  intends  to  remain  qualified  as  a  regulated
investment  company (a 'RIC') under  Subchapter M of the Code.  As a RIC, a Fund
(as   opposed    to    its    shareholders)   will    not    be    subject    to
 
                                      -20-
 


<PAGE>
federal  income taxes  on the  net investment income  and capital  gains that it
distributes to  its  shareholders,  provided  that  at  least  90%  of  its  net
investment  income and  realized net short-term  capital gains in  excess of net
long-term capital  losses for  the taxable  year is  distributed. The  Portfolio
intends  to qualify as a  partnership for federal income  tax purposes. As such,
the Portfolio generally should not be subject to tax. The status of the Fund  as
a  regulated  investment  company  is  dependent  on,  among  other  things, the
Portfolio's continued  qualification as  a partnership  for federal  income  tax
purposes.
 
Distributions of net long-term capital gains in excess of net short-term capital
losses are taxable to Fund shareholders as long-term capital gains regardless of
how  long a shareholder  has held shares  in the Fund  and regardless of whether
received in the form of cash  or reinvested in additional shares.  Distributions
of net investment income, realized net short-term capital gains in excess of net
long-term   capital  losses  and   net  gains  from   certain  foreign  currency
transactions are taxable as ordinary income to shareholders of the Fund  whether
such  distributions are received in the form of cash or reinvested in additional
shares. Annual statements as to the current federal tax status of  distributions
will  be mailed to shareholders after the end  of the taxable year for the Fund.
Distributions to corporate  shareholders of the  Fund will not  qualify for  the
dividends-received  deduction because the income of the Fund will not consist of
dividends paid by United States corporations.
 
Any gain or  loss realized on  the redemption or  exchange of Fund  shares by  a
shareholder  who is  not a  dealer in  securities generally  will be  treated as
long-term capital gain or loss  if the shares have been  held for more than  one
year,  and  otherwise as  short-term  capital gain  or  loss. However,  any loss
realized by a shareholder upon the redemption or exchange of shares in the  Fund
held  for six months or less will be  treated as a long-term capital loss to the
extent of any long-term capital  gain distributions received by the  shareholder
with respect to such shares. In addition, no loss will be allowed on the sale or
other  disposition of shares  of the Fund if,  and to the  extent that, within a
period beginning 30 days before the date of such sale or disposition and  ending
30  days  after  such  date,  the  holder  acquires  (such  as  through dividend
reinvestment) securities that are substantially  identical to the shares of  the
Fund.
 
The  Fund will generally be subject to an excise  tax of 4% on the amount of any
income  or  capital  gains,  above  certain  permitted  levels,  distributed  to
shareholders  on  a  basis such  that  such income  or  gain is  not  taxable to
shareholders in  the  calendar  year  in  which  it  was  earned  by  the  Fund.
Furthermore,  dividends  declared in  October, November  or December  payable to
shareholders of record  on a  specified date  in such a  month and  paid in  the
following  January will be treated as having  been paid by the Fund and received
by each shareholder in December. Under this rule, therefore, shareholders may be
taxed in one year on dividends or distributions actually received in January  of
the following year.
 
The  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  Portfolio's total assets at the  close of any taxable  year
consists  of stock or securities of foreign  corporations, the Fund may elect to
treat its proportionate share of foreign  income taxes paid by the Portfolio  as
paid  directly by the Fund's  shareholders. The 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 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 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 Portfolio  or the  Fund purchases  shares in  certain foreign investment
entities, referred to as 'passive foreign investment companies,' the 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 Fund as a dividend to its shareholders. If the 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  Fund would be required each year to
include in  income,  and  distribute  to shareholders  in  accordance  with  the
distribution requirement set
 
                                      -21-
 


<PAGE>
forth  above, the Fund's pro rata share of the ordinary earnings and net capital
gains of the company, whether or not distributed to the Fund.
 
Distributions of net investment income or net long-term capital gains will  have
the effect of reducing the net asset value of the Fund's shares by the amount of
the  distribution. If the net asset value is reduced below a shareholder's cost,
the distribution will  nonetheless be taxable  as described above,  even if  the
distribution  represents a return of invested capital. Investors should consider
the tax implications  of buying shares  just prior to  a distribution, when  the
price of shares may reflect the amount of the forthcoming distribution.
 
If  a correct and certified  taxpayer identification number is  not on file, the
Fund is required,  subject to  certain exemptions,  to withhold  31% of  certain
payments   made  or   distributions  declared   to  non-corporate  shareholders.
Shareholders should be aware that, under applicable regulations, the Fund may be
fined up  to  $50 annually  for  each account  for  which a  certified  taxpayer
identification  number is not provided. In the event that such a fine is imposed
with respect to any uncertified account in any year, a corresponding charge  may
be made against that account.
 
This  discussion of tax consequences is based on U.S. federal tax laws in effect
on the date of this Prospectus. These laws and regulations are subject to change
by legislative  or  administrative  action, possibly  with  retroactive  effect.
Investors  are urged to consult their own  tax advisors with respect to specific
questions as to federal taxes and with respect to the applicability of state  or
local taxes. See 'Taxes' in the SAI.
 
ADDITIONAL INFORMATION
 
The  Fund  will  send  its  shareholders  annual  and  semi-annual  reports. The
financial statements appearing in annual reports will be audited by  independent
accountants.  Shareholders will also be sent  confirmations of each purchase and
redemption and periodic  statements reflecting all  account activity,  including
dividends  and any distributions whether reinvested in additional shares or paid
in cash.
 
Shareholders of  certain Eligible  Institutions may  be given  the privilege  to
initiate  transactions  automatically  by  telephone  upon  opening  an account.
However, an investor should be aware that a transaction authorized by  telephone
and  reasonably believed to be genuine by  the Company, the Branch, the Eligible
Institution, the Transfer Agent or the  Distributor may subject the investor  to
risk  of loss if such  instruction is subsequently found  not to be genuine. The
Company and its service providers  will employ reasonable procedures,  including
requiring investors to give a form of personal identification and tape recording
of telephonic instructions, to confirm that telephonic instructions by investors
are  genuine; if it does not,  it or the service provider  may be liable for any
losses due to unauthorized or fraudulent instructions.
 
The Fund may make historical  performance information available and may  compare
its  performance to other  investments or relevant  indices, including data from
Lipper Analytical  Services, Inc.,  Micropal  Inc., Morningstar  Inc.,  Ibbotson
Associates,  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 Fund may advertise 'total return'. The total return shows what an investment
in  the Fund would have earned over a specified period of time (one, five or ten
years or  since commencement  of operations,  if less)  assuming that  all  Fund
distributions  and dividends were reinvested on  the reinvestment dates and less
all recurring  fees  during the  period  and  assuming the  redemption  of  such
investment at the end of each period. This method of calculating total return is
required  by regulations  of the  SEC. Total  return data  similarly calculated,
unless otherwise indicated,  over other specified  periods of time  may also  be
used.  All  performance figures  are based  on historical  earnings and  are not
intended to indicate future performance. Performance information may be obtained
by clients of an Eligible Institution by calling the Eligible Institution, 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 four series, three of which are described in this
Statement of Additional Information ('SAI').  These three series (each a  'Fund'
and  collectively, the  'Funds') consist  of: UBS  Bond Fund;  UBS International
Equity Fund; and UBS U.S. Equity Fund. The Company, a Maryland corporation,  was
organized on November 16, 1995. The Company's executive offices are located at 6
St. James Avenue, 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  three Portfolios: UBS  Bond Portfolio; UBS
U.S. Equity Portfolio;  and UBS  International Equity Portfolio.  UBS Bond  Fund
invests  in UBS Bond Portfolio; UBS U.S.  Equity Fund invests in UBS U.S. Equity
Portfolio; and UBS International Equity Fund invests in UBS International Equity
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  U.S. EQUITY  FUND (the 'U.S.  Equity Fund') is  designed for investors
seeking long-term capital  appreciation and the  potential for a  high level  of
current  income  with  lower investment  risk  and volatility  than  is normally
available from common stock funds. The U.S. Equity Fund attempts to achieve  its
investment  objective  by investing  all of  its investable  assets in  UBS U.S.
Equity Portfolio (the 'U.S. Equity Portfolio'), a series of the Trust having the
same investment objective as the U.S. Equity Fund.
 
     Under normal circumstances,  at least  80% of the  U.S. Equity  Portfolio's
assets   will  be  invested  in  income-producing  domestic  equity  securities,
including dividend-paying common stocks and securities that are convertible into
common stocks. The U.S.  Equity Portfolio's primary  investments are the  common
stocks of established, high-quality U.S. corporations.
 
                                     SAI-1
 


<PAGE>
     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. The International
Equity Fund attempts to  achieve its investment objective  by investing all  its
investable  assets  in 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.
 
MONEY MARKET INSTRUMENTS
 
     As  discussed  in the  Prospectus,  each Fund  may  invest in  money market
instruments to the extent consistent with its investment objective and policies.
A description  of the  various types  of money  market instruments  that may  be
purchased appears below. See 'Quality and Diversification Requirements'.
 
     U.S. TREASURY SECURITIES. Each Fund may invest in direct obligations of the
U.S.  Treasury,  including Treasury  Bills, Notes  and Bonds,  all of  which are
backed as to principal and interest payments by the full faith and credit of the
United States.
 
     ADDITIONAL U.S. GOVERNMENT OBLIGATIONS. Each Fund may invest in obligations
issued or guaranteed  by U.S.  Government agencies  or instrumentalities.  These
obligations  may or  may not  be backed by  the 'full  faith and  credit' of the
United States. In the case of securities not backed by the full faith and credit
of the United  States, each  Fund must look  principally to  the federal  agency
issuing  or guaranteeing the  obligation for ultimate repayment,  and may not be
able to assert a claim against the United States itself in the event the  agency
or  instrumentality does not meet its commitments. Securities in which each Fund
may invest that are not backed by the full faith and credit of the United States
include, but are not limited to, obligations of the Tennessee Valley  Authority,
the  Federal Home Loan Mortgage Corporation and the U.S. Postal Service, each of
which has the right to  borrow from the U.S.  Treasury to meet its  obligations,
and  the obligations of the Federal Farm Credit System and the Federal Home Loan
Banks, both of whose obligations may be satisfied only by the individual credits
of each issuing agency. Securities that are backed by the full faith and  credit
of  the United  States include obligations  of the  Government National Mortgage
Association, the Farmers Home Administration and the Export-Import Bank.
 
     BANK OBLIGATIONS. Each Fund,  unless otherwise noted  in the Prospectus  or
below,  may  invest in  negotiable certificates  of  deposit, time  deposits and
bankers' acceptances of  (i) banks,  savings and loan  associations and  savings
banks  that have more than  $2 billion in total  assets (the 'Asset Limitation')
and are organized under the laws of the United States or any state, (ii) foreign
branches of these banks or of foreign banks of equivalent size (Euros) and (iii)
U.S.  branches  of  foreign  banks  of  equivalent  size  (Yankees).  The  Asset
Limitation  is not  applicable to  the International  Equity Fund.  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 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-2
 


<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 Fund, UBS International Investment London Limited ('UBSII'
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 Custodian. If the
seller defaults, a Portfolio might incur a  loss if the value of the  collateral
securing  the repurchase agreement declines and might incur disposition costs in
connection  with  liquidating  the   collateral.  In  addition,  if   bankruptcy
proceedings   are  commenced  with  respect  to  the  seller  of  the  security,
realization of proceeds upon disposition of the collateral by the Portfolio  may
be delayed or limited.

CORPORATE BONDS AND OTHER DEBT SECURITIES
 
     Each  Portfolio, with  the exception of  the Bond Portfolio,  may invest in
other debt  securities with  remaining  effective maturities  of not  more  than
thirteen  months,  including  without limitation  corporate  and  foreign bonds,
asset-backed securities and  other obligations  described in  the Prospectus  or
this SAI.
 
     As  discussed in the Prospectus, the Bond Portfolio may invest in bonds and
other debt securities of domestic and  foreign issuers to the extent  consistent
with  its 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.  Because asset-backed
securities are  relatively new,  the market  experience in  these securities  is
limited  and the market's ability to sustain liquidity through all phases of the
market cycle has not been tested.
 
EQUITY INVESTMENTS
 
     As discussed in the  Prospectus, the U.S.  Equity and International  Equity
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
 
                                     SAI-4
 


<PAGE>
and earnings are subordinated to the claims of all creditors, but are senior  to
the claims of common stockholders.
 
FOREIGN INVESTMENTS
 
   
     The   International  Equity  Portfolio  makes  substantial  investments  in
companies based in  foreign countries.  The Bond  Portfolio may  also invest  in
certain  foreign securities. The  Bond Portfolio does not  expect to invest more
than 25% of its total  assets at the time of  purchase in securities of  foreign
issuers.  Foreign investments may be made  directly in the securities of foreign
issuers or  in  the  form  of  American  Depositary  Receipts  ('ADRs'),  Global
Depositary   Receipts  ('GDRs')   or  European   Depositary  Receipts  ('EDRs').
Generally, ADRs 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, or European,  in
the case of EDRs, securities markets.
    
 
     Because  investments in foreign securities  may involve foreign currencies,
the value of the International Equity and Bond Portfolios' assets as measured in
U.S. dollars may be affected, favorably  or unfavorably, by changes in  currency
rates and in exchange control regulations, including currency blockage. The Bond
and  International Equity  Portfolios may  enter into  foreign currency exchange
transactions  in   connection  with   the  settlement   of  foreign   securities
transactions   or  to  manage   their  currency  exposure   related  to  foreign
investments.  The  Portfolios  will  not   enter  into  such  transactions   for
speculative  purposes. For a description of  the risks associated with investing
in foreign securities, see 'Additional Investment Information and Risk  Factors'
in the Prospectus.
 
ADDITIONAL INVESTMENTS
 
     WHEN-ISSUED  AND DELAYED  DELIVERY SECURITIES. Each  Portfolio may purchase
securities on a when-issued or delayed delivery basis. For example, delivery  of
and  payment for these securities can take place  a month or more after the date
of the purchase commitment. The purchase price and the interest rate payable, if
any, on the securities are fixed on the purchase commitment date or at the  time
the  settlement date is fixed. The value of such securities is subject to market
fluctuation and no interest accrues to a Portfolio until settlement takes place.
At the  time  a Portfolio  makes  the commitment  to  purchase securities  on  a
when-issued  or delayed delivery basis, it  will record the transaction, reflect
the value of such securities each day in determining its net asset value and, if
applicable, calculate the  maturity for  the purposes of  average maturity  from
that  date. At the time  of settlement, a when-issued  security may be valued at
less than the purchase  price. To facilitate  such acquisitions, each  Portfolio
will  maintain  with  the Custodian  a  segregated account  with  liquid assets,
consisting of  cash,  U.S. Government  securities  or other  high-grade,  liquid
securities,  in an amount  at least equal  to the value  of such commitments. On
delivery dates for such transactions,  each Portfolio will meet its  obligations
from maturities or sales of the securities held in the segregated account and/or
from  cash flow.  If a Portfolio  chooses to dispose  of the right  to acquire a
when-issued security prior to its acquisition, it could, as with the disposition
of any  other  portfolio  obligation,  incur  a  gain  or  loss  due  to  market
fluctuation.  It  is the  current policy  of  each Portfolio  not to  enter into
when-issued commitments exceeding in  the aggregate 15% of  the market value  of
that  Portfolio's  total  assets, less  liabilities  (excluding  the obligations
created by when-issued commitments).
 
     INVESTMENT COMPANY SECURITIES. Securities of other investment companies may
be acquired by each Fund to the  extent that such purchases are consistent  with
that entity's investment objectives and restrictions and are permitted under the
Investment  Company  Act of  1940, as  amended  (the '1940  Act'). The  1940 Act
requires that, as determined immediately after a purchase is made, (i) not  more
than  5%  of the  value  of the  Fund's  total assets  will  be invested  in the
securities of any one investment company, (ii) not more than 10% of the value of
the Fund's total assets will be  invested in securities of investment  companies
as a group and
 
                                     SAI-5
 


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


<PAGE>
     As  to illiquid investments, a Portfolio is subject to a risk that it might
not be  able  to sell  such  securities at  a  price that  the  Portfolio  deems
respective  of their value. Where an  illiquid security must be registered under
the Securities Act of 1933, as amended (the 'Securities Act'), before it may  be
resold,  the Portfolio may be  obligated to pay all  or part of the registration
expenses and a  considerable period may  elapse between the  time the  Portfolio
decides  to  sell and  the  time the  Portfolio is  permitted  to sell  under an
effective registration  statement.  If, during  such  a period,  adverse  market
conditions  develop, the Portfolio might obtain a less favorable price than that
which prevailed  when  it decided  to  sell.  When the  Portfolios  value  these
securities,   they  will  take  into  account   the  illiquid  nature  of  these
instruments.
 
QUALITY AND DIVERSIFICATION REQUIREMENTS
 
     Each Portfolio intends to meet the diversification requirements of the 1940
Act. To meet these  requirements, 75% of the  Portfolio's assets are subject  to
the  following fundamental  limitations: (1) the  Portfolio may  not invest more
than 5%  of  its total  assets  in the  securities  of any  one  issuer,  except
obligations  of the U.S. Government, its  agencies and instrumentalities and (2)
the Portfolio may not own more than 10% of the outstanding voting securities  of
any  one issuer.  As for  the 25%  of a  Portfolio's assets  not subject  to the
limitation described above, there is no limitation on investment of these assets
under the 1940 Act, so that all of such assets may be invested in securities  of
any  one issuer,  subject to the  limitation of any  applicable state securities
laws. Investments not subject to  the limitations described above could  involve
an  increased risk to  a Portfolio should an  issuer, or a  state or its related
entities, be unable to make interest or principal payments or should the  market
value of such securities decline. See 'Investment Restrictions'.
 
     BOND  PORTFOLIO. The  Bond Portfolio  invests principally  in a diversified
portfolio of 'high  grade' and 'investment  grade' securities. Investment  grade
debt  is rated, on  the date of  investment, within the  four highest ratings of
Moody's Investors Service, Inc. ('Moody's'), currently Aaa, Aa, A and Baa, or of
Standard & Poor's Corporation  ('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.
 
     U.S. EQUITY  AND  INTERNATIONAL  EQUITY PORTFOLIOS.  The  U.S.  Equity  and
International  Equity 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

International  Equity Portfolio refer to the  Adviser and/or the Sub-Adviser, as
appropriate.

<PAGE>
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 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
 
                                     SAI-8
 


<PAGE>
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 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
 
                                     SAI-9
 


<PAGE>
respect to coverage of options and futures contracts by mutual funds, and if the
guidelines  so require, will set aside appropriate liquid assets in a segregated
custodial account  in the  amount prescribed.  Securities held  in a  segregated
account  cannot be  sold and  will be  considered illiquid  securities while the
futures contract or option is outstanding,  unless they are replaced with  other
suitable  assets. As a result, there is  a possibility that the segregation of a
large percentage of a  Portfolio's assets could  impede portfolio management  or
the   Portfolio's  ability  to   meet  redemption  requests   or  other  current
obligations.
 
INVESTMENT RESTRICTIONS
 
     The Funds  have  adopted  the  following  fundamental  and  non-fundamental
investment restrictions (as defined and distinguished below); to the extent that
a  fundamental policy  and non-fundamental  policy apply  to a  given investment
activity or strategy, the more restrictive policy shall govern.
 
     FUNDAMENTAL INVESTMENT RESTRICTIONS. The investment restrictions below have
been  adopted  by  the  Company's  Board  of  Directors  (the  'Board'  or   the
'Directors')   with  respect  to  each  Fund   and  by  the  Trustees  for  each
corresponding  Portfolio.  Except  where   otherwise  noted,  these   investment
restrictions  are 'fundamental' policies  which, under the 1940  Act, may not be
changed without the 'vote of a majority of the outstanding voting securities' of
the Fund or the Portfolio, as applicable,  to which they relate. The 'vote of  a
majority  of the outstanding voting securities' under the 1940 Act is the lesser
of (a) 67% or more of the  voting securities present at a shareholders'  meeting
if the holders of more than 50% of the outstanding voting securities are present
or  represented  by  proxy  or  (b) more  than  50%  of  the  outstanding voting
securities. Except as described below, whenever a Fund is requested to vote on a
change  in  the  fundamental   investment  restrictions  of  its   corresponding
Portfolio,  the Company will hold a meeting  of that Fund's shareholders and the
Company will cast that Fund's votes in the Portfolio in proportion to the  votes
cast  by that Fund's shareholders. However,  subject to applicable statutory and
regulatory requirements, a  Fund would not  request a vote  of its  shareholders
with  respect to (a) any proposal relating to its corresponding Portfolio, which
proposal, if made with respect  to the Fund, would not  require the vote of  the
shareholders of the Fund, or (b) any proposal with respect to the Portfolio that
is  identical in all  material respects to  a proposal that  has previously been
approved by shareholders of the Fund.  Any proposal submitted to holders in  the
Portfolio,  and that is not required to be voted on by shareholders of the Fund,
would nevertheless be voted on by the Trustees of the Fund.
 
     The investment restrictions  of each Fund  and its corresponding  Portfolio
are  identical, unless otherwise  specified. Accordingly, references  below to a
Fund also  include  that  Fund's  corresponding  Portfolio  unless  the  context
requires  otherwise;  similarly,  references  to a  Portfolio  also  include the
corresponding Fund  unless  the  context  requires otherwise.  As  a  matter  of
fundamental policy, each Fund and Portfolio may not:
 
1.    Borrow  money, except from  banks for extraordinary  or emergency purposes
      and then only in amounts up to one-third of the value of its total  assets
      (including the amount  borrowed),  less  liabilities  (not  including  the
      amounts borrowed), or  mortgage, pledge, or hypothecate any assets, except
      in  connection  with   any  permitted  borrowing  or   reverse  repurchase
      agreements  (see  Investment  Restriction  No.  7). It  will  not purchase
      securities  while  borrowings  (including  reverse repurchase  agreements)
      exceed  5% of  its net  assets;  provided,  however, that  it may increase
      its interest  in  an open-end  management investment company with the same
      investment   objective  and  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
 
                                     SAI-10
 


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


<PAGE>
 2.    pledge,  mortgage or hypothecate for any purpose  in excess of 10% of the
       Fund's total assets  (taken at  market value),  provided that  collateral
       arrangements  with respect to options  and futures, including deposits of
       initial deposit and variation  margin, and reverse repurchase  agreements
       are not considered a pledge of assets for purposes of this restriction;
 
 3.    purchase  any security or evidence of  interest therein on margin, except
       that such short-term  credit as  may be  necessary for  the clearance  of
       purchases  and  sales  of  securities may  be  obtained  and  except that
       deposits  of  initial  deposit  and  variation  margin  may  be  made  in
       connection with the purchase, ownership, holding or sale of futures;
 
 4.    sell securities it does not own such that the dollar amount of such short
       sales  at any one time exceeds 25% of the net equity of the Fund, and the
       value of securities of any one issuer in which the Fund is short  exceeds
       the  lesser of 2.0% of the value of  the Fund's net assets or 2.0% of the
       securities of any class of any U.S. issuer, and provided that short sales
       may be made only in those securities which are fully listed on a national
       securities exchange  or  a  foreign exchange  (This  provision  does  not
       include  the sale of securities the  Fund contemporaneously owns or where
       the Fund has the right to obtain securities equivalent in kind and amount
       to those  sold, i.e.,  short sales  against the  box.) (The  Fund has  no
       current intention to engage in short selling.);
 
 5.    invest for the purpose of exercising control or management;
 
 6.    purchase  securities issued by any  investment company except by purchase
       in the open market where no commission  or profit to a sponsor or  dealer
       results  from such purchase other than the customary broker's commission,
       or except when such purchase, though not made in the open market, is part
       of a plan of merger or consolidation; provided, however, that  securities
       of  any investment  company will  not be purchased  for the  Fund if such
       purchase at the time thereof would cause (a) more than 10% of the  Fund's
       total  assets  (taken at  the  greater of  cost  or market  value)  to be
       invested in  the securities  of such  issuers; (b)  more than  5% of  the
       Fund's  total assets (taken at the greater of cost or market value) to be
       invested in  any one  investment company;  or  (c) more  than 3%  of  the
       outstanding voting securities of any such issuer to be held for the Fund;
       provided  further that, except in the  case of a merger or consolidation,
       the Fund shall  not purchase  any securities of  any open-end  investment
       company  unless (1) the  Fund's investment adviser  waives the investment
       advisory fee with respect to assets invested in other open-end investment
       companies and (2) the Fund incurs no sales charge in connection with that
       investment;
 
 7.    invest more than 10% of the Fund's total assets (taken at the greater  of
       cost or market value) in securities (excluding Rule 144A securities) that
       are restricted as to resale under the 1933 Act;
 
 8.    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 1933 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
 
                                     SAI-12
 


<PAGE>
       statistical   rating  agency  and  the  Fund's  Board  of  Directors  has
       determined that  the commercial  paper is  of equivalent  quality and  is
       liquid;
 
10.    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 if, as a result, more than 2% of
       the Fund's  net assets  would be  invested in  warrants not  listed on  a
       recognized  United  States  or  foreign  stock  exchange,  to  the extent
       permitted by applicable state securities laws;
 
12.    write  puts  and  calls  on  securities  unless  each  of  the  following
       conditions are met: (a) the security underlying the put or call is within
       the  investment policies  of the  Fund and  the option  is issued  by the
       Options Clearing Corporation, except for  put and call options issued  by
       non-U.S.  entities  or  listed  on  non-U.S.  securities  or  commodities
       exchanges; (b) the aggregate value of the obligations underlying the puts
       determined as of the date the options are sold shall not exceed 5% of the
       Fund's net assets; (c) the securities subject to the exercise of the call
       written by the Fund  must be owned by  the Fund at the  time the call  is
       sold  and must continue to  be owned by the Fund  until the call has been
       exercised, has lapsed, or the Fund has purchased a closing call, and such
       purchase has been confirmed, thereby extinguishing the Fund's  obligation
       to  deliver securities pursuant to  the call it has  sold; and (d) at the
       time a put is written, the Fund establishes a segregated account with its
       custodian consisting  of cash  or short-term  U.S. Government  securities
       equal  in value  to the  amount the  Fund will  be obligated  to pay upon
       exercise of the  put (this account  must be maintained  until the put  is
       exercised, has expired, or the Fund has purchased a closing put, which is
       a put of the same series as the one previously written);
 
13.    buy and sell puts and calls on securities, stock index futures or options
       on  stock index  futures, or  financial futures  or options  on financial
       futures unless:  (a)  the options  or  futures are  offered  through  the
       facilities  of  a  national securities  association  or are  listed  on a
       national securities  or commodities  exchange, except  for put  and  call
       options  issued by non-U.S. entities or  listed on non-U.S. securities or
       commodities exchanges;  (b)  the  aggregate premiums  paid  on  all  such
       options  which are held at any time do not exceed 20% of the Fund's total
       net assets;  (c)  the aggregate  margin  deposits required  on  all  such
       futures  or options  thereon held  at any  time do  not exceed  5% of the
       Fund's total assets; and (d) such activities are permitted by  Regulation
       4.5 under the Commodity Exchange Act; and
 
14.    distribute securities that are not readily marketable to residents of the
       State of Arizona when effecting redemptions in kind.
 
     ALL FUNDS. There will be no violation of any investment restriction if that
restriction  is  complied  with  at  the  time  the  relevant  action  is  taken
notwithstanding a later change in market value of an investment, in net or total
assets, in the securities rating of the investment or any other later change.

DIRECTORS AND TRUSTEES
 
DIRECTORS
 
   
     The Company's Board consists of three  directors. The same persons who  are
the  Company's Directors are  also the Trust's Trustees.  The Company's Board is
responsible for  the  overall management  of  the Fund,  including  the  general
supervision  and review  of its investment  activities. The  Company's Board, in
turn, elects the officers of the Company. Similarly, the Trustees, as such,  are
responsible  for  the overall  management of  the  Trust, including  the general
supervision and review of its investment activities. The officers of the Company
hold  similar   positions   with  the   Trust   with  substantially   the   same
responsibilities.  The  addresses  and principal  occupations  of  the Company's
Director's and officers and the Trust's Trustees and officers are listed  below.
As  of February 28, 1997 the  Directors and officers of  the Company owned of
record, as a group, less than 1% of the outstanding shares of the Company.  None
of  the Trustees or Directors or officers receives compensation from the Company
or the  Trust  exceeding $60,000  per  fiscal year.  Every  Director who  is  an
'Interested  Person' (within the meaning of the 1940 Act) of the Company is also
an 'Interested Person'  of the Trust.  Similarly, every Director  who is not  an
'Interested Person' of the Company is not an 'Interested Person' of the Trust.

INVESTMENT ADVISER AND FUNDS SERVICES AGENT
 
     Pursuant to Investment Advisory Agreements between the Trust and Union Bank
of Switzerland, New York Branch, the Branch serves as the Portfolios' investment
adviser.  Pursuant  to  a  Sub-Advisory Agreement  between  the  Branch  and UBS
International Investment London Limited, UBSII serves as the sub-adviser to  the
International  Equity  Portfolio.  The  Branch, which  operates  out  of offices
located  at  299  Park  Avenue,  New   York,  New  York,  is  licensed  by   the
Superintendent  of Banks of the State of New  York under the banking laws of the
State of  New  York  and is  subject  to  state and  federal  banking  laws  and
regulations  applicable to a foreign bank  that operates a state licensed branch
in the United  States. UBSII is  a wholly-owned direct  subsidiary of UBS  Asset
Management  London  Limited, which  is  a direct  subsidiary  of UBS  UK Holding
Limited, which is in  turn a wholly-owned direct  subsidiary of the Bank.  UBSII
was  organized  under the  laws of  the United  Kingdom on  June 19,  1986. (The
Adviser and the  Sub-Adviser are  collectively referred to  as the  'Advisers'.)
Subject  to the supervision of the Trustees, the Adviser, and in the case of the
International  Equity  Portfolio,  UBSII,   makes  the  Portfolios'   day-to-day
investment  decisions, arranges for the  execution of portfolio transactions and
generally  manages   each   Portfolio's   investments   and   provides   certain
administrative services.
 
     The investment advisory services provided by the Advisers to the Portfolios
are  not exclusive under the terms of  the advisory agreements. The Advisers are
free to  and do  render  similar investment  advisory  services to  others.  The
Advisers  serve  as  investment  advisers  to  personal  investors  and  act  as
fiduciaries for  trusts, estates  and  employee benefit  plans. Certain  of  the
assets of trusts and estates under management are invested in common trust funds
for which the Advisers serve as trustees. The accounts managed or advised by the
Advisers have
 
                                     SAI-16
 


<PAGE>
varying investment objectives and the Advisers invest assets of such accounts in
investments  substantially similar to, or the  same as, those which are expected
to constitute the  principal investments  of the Portfolios.  Such accounts  are
supervised  by officers and employees of  the Advisers (or their affiliates) who
may also be  acting in  similar capacities  for the  Portfolios. See  'Portfolio
Transactions'.
 
   
     The Bank has branches, agencies, representative offices and subsidiaries in
Switzerland  and in more  than 40 cities outside  Switzerland, including, in the
United States,  New  York City,  Houston,  Los  Angeles and  San  Francisco.  In
addition  to the receipt of  deposits and the making  of loans and advances, the
Bank, through its offices and subsidiaries  (including UBSII) engages in a  wide
range  of  banking  and  financial  activities  typical  of  the  world's  major
international banks,  including  fiduciary, investment  advisory  and  custodial
services   and  foreign  exchange  in  the   United  States,  Swiss,  Asian  and
Euro-capital markets. The Bank is one of the world's leading asset managers  and
has  been active  in New York  City since 1946.  At December 31,  1996, the Bank
(including its consolidated subsidiaries) had total assets of $326.7 billion and
equity capital and reserves of $17.1 billion.
    
 
     BOND FUND. The Adviser's fixed income analysts have extensive experience in
selecting bonds  and monitoring  their performance.  These analysts  review  the
creditworthiness  of individual  issuers as  well as  the broad  economic trends
likely to affect the bond markets.
 
     U.S.  EQUITY  FUND.  While  many  investment  advisers  evaluate  companies
primarily  on their earnings and their  price/earnings ratio, the Adviser uses a
different investment approach. The Adviser believes that dividend yields, rather
than earnings, are the best indicators of future performance. Consequently,  the
Adviser will select attractively priced stocks with high dividends. In addition,
the  Adviser's  analysts  often  meet with  company  managers,  often  contact a
company's suppliers, review the business operations and financial statements  of
companies  and  try to  'get  behind' the  numbers  to gain  a  true sense  of a
company's value.
 
     INTERNATIONAL  EQUITY  FUND.  The  Sub-Adviser's  analysts  have  extensive
experience  in  managing  international  portfolios.  These  analysts  track the
performance of more than  1,600 companies around the  world, and pay  particular
attention to the energy, life sciences, technology and financial industries.
 
     The  Sub-Adviser is  a registered  investment adviser  under the Investment
Advisers Act of 1940, as amended.
 
   
     The prospectus for each of the Funds contain a description of fees  payable
to  the Adviser. For the period from  April 2, 1996 (commencement of operations)
to  December  31,  1996,   the  Bond  Portfolio,   U.S.  Equity  Portfolio   and
International Equity Portfolio paid investment advisory fees equal to $0, $0 and
$13,839, respectively.
    
 
   
         The Branch has voluntarily  agreed to waive its fees and reimburse each
Fund and its corresponding  Portfolio for their respective operating expenses to
the extent that the operating expenses  (excluding  extraordinary  items) of the
Bond Fund,  U.S.  Equity Fund and the  International  Equity Fund exceed,  on an
annual basis, 0.80%, 0.90% and 0.95%, respectively, of such Fund's average daily
net assets.  The Branch may modify or discontinue this expense limitation at any
time in the  future  with 30  days'  prior  notice  to the  affected  Fund.  See
'Expenses'.  For the period April 2, 1996  (commencement of operations)  through
December  31,  1996,  UBS  reimbursed  the  Bond  Fund,  U.S.  Equity  Fund  and
International  Equity Fund for expenses totaling  $80,050,  $93,511 and $52,899,
respectively.
    
 
   
     Pursuant   to  the  Sub-Advisory  Agreement,  the  Sub-Adviser,  under  the
supervision of the  Trustees and  the Adviser, makes  the day-to-day  investment
decisions  for  the  International  Equity  Portfolio.  Under  the  Sub-Advisory
Agreement, the Adviser has agreed to pay the Sub-Adviser a fee, calculated daily
and payable monthly,  equal on  an annual basis  to 0.75%  of the  International
Equity  Portfolio's first $20 million  of average net assets,  0.50% of the next
$30 million of average net assets, and 0.40% of average net assets in excess  of
$50  million.  The Adviser  is solely  responsible  for paying  this fee  to the
Sub-Adviser. For the
    
 
                                     SAI-17
 


<PAGE>
   
period from April 2, 1996 to December 31, 1996, the Adviser paid $154,659 to the
Sub-Adviser on behalf of the International Equity Portfolio.
    
 
     The Investment  Advisory Agreements  and Sub-Advisory  Agreement will  each
continue in effect until February 1998, and thereafter will be subject to annual
approval  by the Trustees  or the vote  of a majority  of the outstanding voting
securities (as defined  in the  1940 Act) of  each Portfolio,  provided that  in
either  case the continuance also is approved  by a majority of the Trustees who
are not interested persons  (as defined in  the 1940 Act) of  the Trust by  vote
cast  in person at a meeting called for  the purpose of voting on such approval.
The Investment Advisory and Sub-Advisory Agreements will terminate automatically
if assigned  and are  terminable at  any time  without penalty  by a  vote of  a
majority  of the Trustees or by a vote  of the holders of a majority (as defined
in the  1940 Act)  of the  Portfolio's outstanding  shares on  60 days'  written
notice  to  the Adviser  or Sub-Adviser  as  applicable. Whenever  a Fund,  as a
shareholder of a Portfolio, is  required by the 1940  Act to vote its  Portfolio
interest,  the Company will hold a meeting  of that Fund's shareholders and will
vote its  Portfolio  interests  proportionately as  instructed  by  that  Fund's
shareholders.   See  'Organization'.  Each  Investment  Advisory  Agreement  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-Adviser) 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-Adviser were prohibited from providing these services
to the Funds or the Portfolios, it is expected that the Directors and  Trustees,
as applicable, would
 
                                     SAI-18
 


<PAGE>
recommend  to shareholders that they approve new agreements with other qualified
service providers.
 
ADMINISTRATORS
 
     Under Administrative Services  Agreements with the  Company and the  Trust,
Signature  Broker-Dealer  Services, Inc.  ('Signature') and  Signature Financial
Group (Grand Cayman) Limited ('Signature-Cayman') serve as the Administrators of
the  Funds  and   the  Portfolios,   respectively  (in   such  capacities,   the
'Administrators').   In   these  capacities,   Signature   and  Signature-Cayman
administer all aspects of their day-to-day operations subject to the supervision
of the Directors and the Trustees, as applicable, except as set forth under  the

office facilities  and ordinary  clerical and  related services  for  day-to-day
operations,  including record-keeping responsibilities; (ii) take responsibility

and  Portfolios' shareholders,  the SEC,  and state  securities commissions; and
(iii) perform such administrative and managerial oversight of the activities  of
the  Funds'  and  Portfolios'  custodian, transfer  agent  and  other  agents or
independent contractors as the Directors and Trustees, respectively, may  direct
from  time to time. Signature  is also responsible for  monitoring the status of
each Fund as a regulated investment  company under the Internal Revenue Code  of
1986, as amended (the 'Code').
 
   
     The  prospectus for each Fund contains a description of fees payable to the
Administrator pursuant to the Company's Administrative Services Agreements  with
each  Fund. For  the period from  April 2, 1996  to December 31,  1996, the Bond
Fund, U.S. Equity  Fund and International  Equity Fund paid  $1,526, $2,593  and
$4,131 in administrative fees, respectively.
    
 
   
     Under  the Trust's  Administrative Services  Agreement, each  Portfolio has
agreed to  pay Signature-Cayman  a fee,  calculated daily  and payable  monthly,
equal on an annual basis to 0.05% of its average net assets. For the period from
April 2, 1996 to December 31, 1996 the Bond Portfolio, U.S. Equity Portfolio and
International  Equity  Portfolio paid  to  Signature-Cayman $14,594,  $7,036 and
$11,712 in administrative fees, respectively.
    
 
     The Administrative Services  Agreements may  be renewed or  amended by  the
Directors   or   Trustees,  as   applicable,   without  shareholder   vote.  The
Administrative Services 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  Administrative
Services 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
 
     Signature  also serves as  the exclusive distributor of  the shares of each
Fund and holds itself available to  receive purchase orders for such shares  (in
this  capacity, the 'Distributor'). The Distributor  has been granted the right,
as each Fund's  agent, to solicit  and accept  orders for the  purchase of  Fund
shares  in accordance with  the terms of the  Distribution Agreement between the
Company, on behalf of each Fund, and the Distributor. The Distribution Agreement
shall continue in  effect with  respect to each  Fund until  February 1997,  and
thereafter  will be subject to annual approval (i) by a vote of the holders of a
majority of each Fund's  outstanding voting securities or  by the Directors  and
(ii) by a vote of a majority of the
 
                                     SAI-19
 

<PAGE>
Directors  who  are  not parties  to  the Distribution  Agreement  or interested
persons (as defined by the 1940 Act) of the Company cast in person at a  meeting
called  for the purpose  of voting on such  approval. The Distribution Agreement
will terminate  automatically  if  assigned  by  either  party  thereto  and  is
terminable  at  any  time, without  penalty,  by a  vote  of a  majority  of the
Directors, a  vote of  a majority  of  such Directors  who are  not  'interested
persons'  of the Company or by a vote of the holders of a majority of the Fund's
outstanding shares, in any case on not more than 60 days' written notice to  the
other party. The Distributor does not receive a fee pursuant to the terms of the
Distribution  Agreement. The principal offices of the Distributor are located at
6 St. James Avenue, Boston, Massachusetts 02116.
 
CUSTODIAN
 
     Investors Bank & Trust Company ('IBT' or the 'Custodian'), whose  principal
offices  are located at 89 South  Street, Boston, Massachusetts 02111, serves as
the custodian and transfer and dividend  disbursing agent for the Funds and  the
Portfolios.  Pursuant to the  Custodian Agreements with the  Trust, on behalf of
each Portfolio,  and the  Company, on  behalf  of each  Fund, the  Custodian  is
responsible  for maintaining the books and records of portfolio transactions and
holding portfolio securities and cash. As transfer agent and dividend disbursing
agent, the Custodian  is responsible for  maintaining account records  detailing
the  ownership of Portfolio and Fund interests and for crediting income, capital
gains and other changes in share ownership to investors' accounts. The Custodian
will  perform  its  duties  as  the  Portfolios'  transfer  agent  and  dividend
disbursing agent from its offices located at 1 First Canadian Place, Suite 2800,
Toronto,  Ontario  M5X1C8, while  its duties  as the  Funds' transfer  agent and
dividend disbursing agent will be performed  at its offices located at 89  South
Street,  Boston, Massachusetts 02111. 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 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  inquiries regarding
account  status and history,  the manner in which  purchases and  redemptions of
shares may be made and certain other matters pertaining to each Fund,  assisting
customers in designating and changing dividend options, account designations and
addresses,  providing  necessary  personnel and  facilities  to  coordinate  the
establishment  and  maintenance  of  shareholder  accounts  and records with the
Funds' Distributor and transfer agent,  assisting  investors seeking to purchase
or redeem Fund shares,  arranging  for the wiring or other  transfer of funds to
and from customer  accounts in connection with orders to purchase or redeem Fund
shares, verifying purchase and redemption orders, transfers among and changes in
accounts and providing  other related  services.  In return for these  services,
each Fund has agreed to pay each  Eligible  Institution a fee equal on an annual
basis to 0.25% of the  average  daily net  assets of such  Fund  represented  by
shares of the Fund owned  during  the period for which  payment is being made by
customers   of  the  Eligible   Institution.   For  the  period  April  2,  1996
(commencement of operations)  through December 31, 1996, the shareholder service
fee for the Bond Fund, U.S. Equity Fund and  International  Equity Fund amounted
to $7,632, $12,965 and $20,658, respectively, all of which were waived.
 
     As discussed under  'Investment Adviser and  Shareholder Servicing  Agent',
the  Glass-Steagall  Act and  other applicable  laws  and regulations  limit the
activities of  bank  holding companies  and  certain of  their  subsidiaries  in
connection  with registered open-end investment companies. The activities of the
Branch under the Shareholder Servicing Agreement, the
 
                                     SAI-20
 

<PAGE>
Investment Advisory Agreement and the  Funds Services Agreement and UBSII  under
the  Sub-Advisory Agreement,  may raise  issues under  these laws.  However, the
Branch and UBSII 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 or  UBSII 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 and UBSII.
 
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 and, from August 1, 1994, will  continue
its  practice under  the name  Price Waterhouse  LLP. 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.
 
   
     For additional  information regarding  waivers  or expense  subsidies,  see
'Management'  in the Prospectus. The Branch  has voluntarily agreed to limit the
total operating expenses of each Fund (including each Fund's proportionate share
of the expenses  incurred by  its corresponding  Portfolio), excluding  ordinary
expenses,  as set forth in each  Fund's Prospectus under the caption 'Expenses'.
The Branch may modify or discontinue  this fee waiver and expense limitation  at
any time in the future with 30 days' prior notice to the affected Fund.
    
 
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.
 
     The  minimum investment requirements  for certain retirement  plans such as
Individual  Retirement   Accounts  ('IRAs'),   Self-Employed  Retirement   Plans
('SERPs'),  401(k) Plans  and other tax-deferred  plans are  $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.
 
     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.

<PAGE>
     Each  Fund may, at its own option, accept securities in payment for shares.
The securities tendered are valued by the methods described in 'Net Asset Value'
as of the day the  Fund shares are purchased. This  is a taxable transaction  to
the investor. Securities may be accepted in payment for shares only if they are,
in  the  judgment of  the Advisers,  appropriate  investments for  the Portfolio
corresponding to  that Fund.  In addition,  securities accepted  in payment  for
shares  must: (i)  meet the  investment objective  and policies  of the relevant
Portfolio; (ii) be acquired by the Fund for investment and not for resale (other
than for resale to the corresponding Portfolio); (iii) be liquid securities that
are not restricted as to transfer either by law or by market liquidity; and (iv)
have a value that is readily ascertainable, as evidenced by a listing on a stock
exchange, over-the-counter market or by readily available market quotations from
a dealer in such securities. Each Fund reserves the right to accept or reject at
its own option any and all securities offered in payment for its shares.
 
REDEMPTION OF SHARES
 
     Investors may redeem  shares of each  Fund as described  in the  Prospectus
under 'Redemption of Shares'.
 
     If the Directors and Trustees determine that it would be detrimental to the
best  interest of the  remaining shareholders of  a Fund or  Portfolio to effect
redemptions wholly or  partly in cash,  payment of the  redemption price may  be
made  in whole  or in  part by  an in-kind  distribution of  securities from the
Portfolio, in lieu of cash, in conformity with the applicable rules of the  SEC.
If   shares  are  redeemed  in-kind,   the  redeeming  shareholder  might  incur
transaction costs in converting the securities into cash. The methods of valuing
portfolio securities distributed to a shareholder are described under 'Net Asset
Value', and such  valuations will be  made as  of the same  time the  redemption
price is determined.
 
     FURTHER REDEMPTION INFORMATION. The right of redemption may be suspended or
the  date of payment  postponed, in the case  of the Company  and the Trust: (i)
during periods when the New York Stock Exchange (the 'NYSE') is closed for other
than weekends  and  holidays  or  when  trading on  the  NYSE  is  suspended  or
restricted;  (ii) during periods in which  an emergency exists, as determined by
the SEC, which causes disposal by a Portfolio of, or evaluation of the net asset
value of, its securities to be unreasonable or impracticable; or (iii) for  such
other periods as the 1940 Act or the SEC may permit.
 
EXCHANGE OF SHARES
 
     An  investor may exchange Fund shares for shares of any other series of the
Company as described under 'Exchange  of Shares' in the prospectuses.  Investors
considering  an exchange  of Fund  shares for  shares of  another Company series
should read the prospectus of the series  into which the transfer is being  made
prior  to such  exchange (see  the section regarding  purchase of  shares in the
appropriate Prospectus). Requests for  exchange are made in  the same manner  as
requests  for redemptions (see the section regarding redemption of shares in the
appropriate Prospectus).  Shares  of  the  acquired  series  are  purchased  for
settlement  when the  proceeds from  redemption become  available. Certain state
securities laws may  restrict the  availability of the  exchange privilege.  The
Company  reserves  the  right  to  discontinue,  alter  or  limit  this exchange
privilege at any time.
 
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.
 
                                     SAI-22
 


<PAGE>
NET ASSET VALUE
 
     Each Fund computes its net asset value once daily at the close of  business
on Monday through Friday as described under 'Net Asset Value' in the Prospectus.
The net asset value will not be computed on a day in which no orders to purchase
or  redeem Fund shares  have been received  or on any  day on which  the NYSE is
closed, including the following legal holidays: New Year's Day, Presidents' Day,
Good Friday, Memorial  Day, Independence  Day, Labor Day,  Thanksgiving Day  and
Christmas  Day. On days when  U.S. trading markets close  early in observance of
these holidays, the Funds and the Portfolios would expect to close for purchases
and redemptions  at  the  same time.  The  days  on which  net  asset  value  is
determined are the Funds' business days.
 
     The  net asset value per share of each Fund equals the value of that Fund's
pro rata interest in its corresponding Portfolio plus the value of all its other
assets not  invested in  the  Portfolio, if  any,  less its  total  liabilities,
divided  by the number  of outstanding shares  of that Fund.  The following is a
discussion of the procedures used by the Portfolios in valuing their assets.
 
     In the case of the Bond Portfolio, 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 Portfolio by using bid quotes from at least
one dealer  or, in  all other  cases,  by taking  into account  various  factors
affecting  market value, including  yields and prices  of comparable securities,
indications as  to  values  from  dealers and  general  market  conditions.  All
portfolio  securities with a remaining maturity of  less than 60 days are valued
by the amortized cost method, whereby such securities are valued at  acquisition
cost  as  adjusted  for amortization  of  premium  or accretion  of  discount to
maturity. Because many  of the  municipal bond  issues outstanding  do not  have
large  principal obligations and because of  the varying risk factors applicable
to each issuer, no readily available market quotations exist for most  municipal
securities.
 
     In  the  case  of  the U.S.  Equity  and  International  Equity Portfolios,
securities listed on domestic  exchanges, other than  options on stock  indices,
are  valued using the  last sales price  on the most  representative exchange at
4:00 p.m. New York time or, in the absence of recorded sales, at the average  of
readily  available closing  bid and  asked prices  on such  exchange or,  in the
absence of  such prices,  at the  readily available  closing bid  price on  such
exchange.  Securities listed on foreign exchanges  are valued at the last quoted
sale price available  before the  time when  net assets  are valued  or, in  the
absence  of such recorded sales, at the average of readily available closing bid
and asked prices  on such exchange  or, in the  absence of such  prices, at  the
readily  available closing bid  price on such  exchange. Unlisted securities are
valued at the average of the quoted bid and asked prices in the over-the-counter
market. The value of each security for which readily available market quotations
exist is based on a decision as  to the broadest and most representative  market
for  such security. For purposes  of calculating net asset  value per share, all
assets and  liabilities  initially  expressed  in  foreign  currencies  will  be
converted into U.S. dollars at the prevailing market rates available at the time
of valuation.
 
     Options on stock indices traded on national securities exchanges are valued
at the close of options trading on such exchanges, which is currently 4:10 p.m.,
New  York time.  Stock index futures  and related options  traded on commodities
exchanges are  valued  at  their last  sales  price  as of  the  close  of  such
commodities  exchanges, which is currently 4:15  p.m., New York time. Securities
or other assets for which market quotations are not readily available are valued
at fair value in accordance with procedures established by and under the general
supervision of  the Trustees.  Such procedures  include the  use of  independent
pricing  services,  indications as  to values  from  dealers and  general market
conditions. Short-term investments that mature in 60 days or less are valued  at
amortized  cost method  (as discussed above)  if their original  maturity was 60
days  or  less,   or  by  amortizing   their  value  on   the  61st  day   prior
 
                                     SAI-23
 


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

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  Portfolio   will  be   undertaken
principally to accomplish its objective in relation to expected movements in the
general  level of  interest rates. The  Bond Portfolio may  engage in short-term
trading consistent with its objectives.
 
   
     In connection  with  portfolio transactions  for  the Bond  Portfolio,  the
Adviser intends to seek best price and execution on a competitive basis for both
purchases  and sales  of securities.  Portfolio turnover  may vary  from year to
year, as well as within a year. The annual portfolio turnover rate for the  Bond
Portfolio  is expected to  be under 100%. For  the period from  April 2, 1996 to
December 31, 1996 the portfolio turnover rate for the Bond Portfolio was 100%.
    
 
   
     In  connection  with  portfolio  transactions  for  the  U.S.  Equity   and
International  Equity Portfolios, the overriding objective is to obtain the best
possible execution of purchase and sale orders. Portfolio turnover may vary from
year to year, as well as within  a year. The annual portfolio turnover rate  for
the  U.S. Equity  and International  Equity Portfolios  is expected  to be under
100%. For the  period from  April 2,  1996 to  December 31,  1996 the  portfolio
turnover  rate for the U.S. Equity  Portfolio and International Equity Portfolio
was 19% and 42%, respectively.
    
 
   
     In selecting a broker, the Adviser or Sub-Adviser, as applicable, considers
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-Adviser decides that  the broker  chosen
will   provide   the  best   possible  execution.   The  Advisers   monitor  the
reasonableness of  the brokerage  commissions  paid in  light of  the  execution
received.  The Trustees regularly  review the reasonableness  of commissions and
other transaction costs  incurred by the  Portfolios in light  of the facts  and
circumstances  deemed relevant, and, in that connection, will review reports and
published data concerning transaction costs incurred by institutional  investors
generally.  Research services  provided by  brokers to  which the  Advisers have
allocated brokerage  business  in  the  past  include  economic  statistics  and
forecasting   services,  industry  and   company  analyses,  portfolio  strategy
services,  quantitative  data,  and  consulting  services  from  economists  and
political  analysts. Research  services furnished  by brokers  are used  for the
benefit of  all the  Adviser's clients  and not  solely or  necessarily for  the
benefit  of  the Portfolios.  The Adviser  believes that  the value  of research
services received  is  not  determinable and  does  not  significantly  increase
expenses.  The Portfolios do not  reduce their fee to  the Adviser by any amount
that might be attributable to  the value of such  services. For the period  from
April  2, 1996  to December  31, 1996, the  Trust paid  brokerage commissions on
behalf of U.S. Equity  Portfolio and International  Equity Portfolio of  $32,019
and $139,846, respectively.

<PAGE>
     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-Adviser, 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-
Adviser 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
issuing shares of common stock, par value $0.001 per share, in four series:  The
UBS  Bond Fund Series; The UBS Tax Exempt  Bond Fund Series; The UBS U.S. Equity
Fund Series; and The UBS International Equity 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
four 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
 
                                     SAI-26
 


<PAGE>
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,  three
series  have  been authorized.  Each  series (i.e.,  a  Portfolio) of  the Trust
corresponds to a Fund of the Company.
 
   
     A copy of the Trust's Declaration of Trust is on file in the office of  its
Administrator.
    
 
     Holders  of interest in the Trust, such as the Funds, may redeem all or any
part of  their interest  in the  Trust at  any time,  upon the  submission of  a
redemption request in proper form. See 'Redemption of Shares'.
 
TAXES
 
     Each  Fund has  qualified and  intends to  remain qualified  as a regulated
investment company (a 'RIC') under  Subchapter M of the Code.  As a RIC, a  Fund
must,  among other  things: (a)  derive at  least 90%  of its  gross income from
dividends, interest, payments  with respect  to loans of  stock and  securities,
gains  from  the  sale or  other  disposition  of stock,  securities  or foreign
currency and other  income (including  but not  limited to  gains from  options,
futures,  and  forward  contracts)  derived  with  respect  to  its  business of
investing in such stock,  securities or foreign currency;  (b) derive less  than
30% of its gross income from the sale or other disposition of stock, securities,
options,  futures or forward  contracts (other than  options, futures or forward
contracts on foreign currencies) held less than three months; and (c)  diversify
its holdings so that, at the end of each fiscal quarter, (i) at least 50% of the
value  of  the  Fund's total  assets  is  represented by  cash,  U.S. Government
securities, investments in other RICs and other securities limited in respect of
any one issuer, to an amount not greater than 5% of the Fund's total assets, and
10% of the outstanding voting securities of  such issuer and (ii) not more  than
25%  of the value of its  total assets is invested in  the securities of any one
issuer (other than U.S. Government securities or the securities of other  RICs).
As a RIC, a Fund (as opposed to its shareholders) will not be subject to federal
income  taxes on the net investment income and capital gains that it distributes
to its shareholders, provided that at least 90% of its net investment income and
realized net short-term capital gains in excess of net long-term capital  losses
for the taxable year is distributed.
 
     For  federal income tax purposes, dividends that  are declared by a Fund in
October, November or December  as of a  record date in  such month and  actually
paid  in January of the following  year will be treated as  if they were paid on
December 31 of the  year declared. Therefore, such  dividends will generally  be
taxable to a shareholder in the year declared rather than the year paid.
 
     Gains  or losses on sales  of securities by a  Portfolio will be treated as
long-term capital gains or  losses if the  securities have been  held by it  for
more  than one year  except in certain  cases where, if  applicable, a Portfolio
acquires a put or writes  a call thereon. Other gains  or losses on the sale  of
securities  will  be short-term  capital gains  or losses.  Gains and  losses on
 
                                     SAI-27
 

<PAGE>
the sale, lapse or other termination of options on securities will be treated as
gains and  losses  from the  sale  of securities.  If  an option  written  by  a
Portfolio  lapses  or is  terminated through  a closing  transaction, such  as a
repurchase by the Portfolio  of the option from  its holder, the Portfolio  will
realize  a short-term  capital gain  or loss,  depending on  whether the premium
income is greater or less than the  amount paid by the Portfolio in the  closing
transaction. If securities are purchased by a Portfolio pursuant to the exercise
of  a put option written by it, the Portfolio will subtract the premium received
from its cost basis in the securities purchased.
 
     Under the  Code, gains  or losses  attributable to  disposition of  foreign
currency  or to foreign currency contracts, or to fluctuations in exchange rates
between the time a Portfolio accrues income or receivables or expenses or  other
liabilities  denominated in a foreign currency and the time a Portfolio actually
collects such income or pays such liabilities, are treated as ordinary income or
ordinary loss. Similarly, gains or losses on the disposition of debt  securities
held  by a  Portfolio, if  any, denominated in  foreign currency,  to the extent
attributable to  fluctuations  in exchange  rates  between the  acquisition  and
disposition dates are also treated as ordinary income or loss.
 
     Forward currency contracts, options and futures contracts entered into by a
Portfolio  may create 'straddles' for U.S.  federal income tax purposes and this
may affect the character and timing of  gains or losses realized by a  Portfolio
on  forward  currency  contracts,  options  and  futures  contracts  or  on  the
underlying securities. 'Straddles' may  also result in the  loss of the  holding
period  of underlying securities  for purposes of  the 30% of  gross income test
described above,  and therefore,  a Portfolio's  ability to  enter into  forward
currency contracts, options and futures contracts may be limited.
 
     Certain options, futures and foreign currency contracts held by a Portfolio
at  the end of  each fiscal year will  be required to be  'marked to market' for
federal income  tax purposes  -- i.e.,  treated as  having been  sold at  market
value.  For  such  options  and  futures contracts,  60%  of  any  gain  or loss
recognized on these deemed sales and  on actual dispositions will be treated  as
long-term  capital gain or loss, and the remainder will be treated as short-term
capital gain or loss regardless of how long the Portfolio has held such  options
or  futures. Any gain or  loss recognized on foreign  currency contracts will be
treated as ordinary income.
 
     FOREIGN SHAREHOLDERS. Distributions of  net investment income and  realized
net  short-term capital  gains in  excess of net  long-term capital  losses to a
shareholder who, as to  the United States, is  a non-resident alien  individual,
fiduciary  of  a  foreign  trust  or  estate,  foreign  corporation  or  foreign
partnership (a 'foreign shareholder') will be subject to U.S. withholding tax at
the rate of  30% (or  lower treaty rate)  unless the  dividends are  effectively
connected  with a U.S. trade  or business of the  shareholder, in which case the
dividends will be subject to  tax on a net income  basis at the graduated  rates
applicable  to U.S. individuals  or domestic corporations.  Distributions of net
long-term capital gains to foreign shareholders will not be subject to U.S.  tax
unless  the distributions are effectively connected with the shareholder's trade
or business in  the United  States or, in  the case  of a shareholder  who is  a
non-resident  alien individual, the shareholder was present in the United States
for more than 182 days during the taxable year and certain other conditions  are
met.
 
     In  the case of a foreign shareholder who is a nonresident alien individual
and who is not otherwise subject to  withholding as described above, a Fund  may
be  required to withhold U.S.  federal income tax at the  rate of 31% unless IRS
Form W-8 is provided. See 'Taxes' in the Prospectus. Transfers by gift of shares
of a Fund by a  foreign shareholder who is  a nonresident alien individual  will
not  be subject to  U.S. federal gift tax,  but the value of  shares of the Fund
held by such a shareholder at his or her death will be includible in his or  her
gross estate for U.S. federal estate tax purposes.
 
     FOREIGN  TAXES. It is expected that  the International Equity Portfolio may
be subject to  foreign withholding taxes  with respect to  income received  from
sources within foreign
 
                                     SAI-28
 


<PAGE>
countries.  In the case of  the International Equity Portfolio,  so long as more
than 50% in value of  the Portfolio's total assets at  the close of any  taxable
year  consists of stock or securities of foreign corporations, the Portfolio may
elect to treat  any foreign  income taxes  paid by it  as paid  directly by  its
shareholders. The Portfolio will make such an election only if it deems it to be
in  the  best  interest  of  its shareholders.  The  Portfolio  will  notify its
shareholders in writing each year if they make the election and of the amount of
foreign income taxes, if any, to be treated as paid by the shareholders. If  the
Portfolio  makes the election, each shareholder of the International Equity Fund
will be required to include  in his or her  income their proportionate share  of
the amount of foreign income taxes paid by the Portfolio and will be entitled to
claim either a credit (subject to the limitations discussed below), or, if he or
she  itemizes deductions, a deduction for his or her share of the foreign income
taxes in computing federal income tax liability. (No deduction will be permitted
in computing an individual's alternative  minimum tax liability.) A  shareholder
who is a nonresident alien individual or a foreign corporation may be subject to
U.S. withholding tax on the 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  Fund from its  foreign source net  investment income will  be treated as
foreign source  income. This  Portfolio's  gains and  losses  from the  sale  of
securities  will generally be treated as derived from U.S. sources, however, and
certain foreign currency gains  and losses likewise will  be treated as  derived
from  U.S.  sources.  The  limitation  on  the  foreign  tax  credit  is applied
separately to foreign source 'passive income', such as the portion of  dividends
received  from  the  Portfolio  that  qualifies  as  foreign  source  income. In
addition, the  foreign  tax  credit  is  allowed  to  offset  only  90%  of  the
alternative  minimum  tax imposed  on corporations  and individuals.  Because of
these limitations, shareholders  may be unable  to claim a  credit for the  full
amount  of their proportionate  shares of the  foreign income taxes  paid by the
International Equity Portfolio.
 
     STATE AND LOCAL TAXES. Each Fund may be subject to state or local taxes  in
jurisdictions  in which that Fund  is deemed to be  doing business. In addition,
the treatment of a Fund  and its shareholders in  those states that have  income
tax  laws might  differ from  treatment under the  federal income  tax laws. For
example, a portion of the dividends  received by shareholders may be subject  to
state  income  tax.  Shareholders should  consult  their own  tax  advisors with
respect to any state or local taxes.

UBS Bond Fund
Notes to Financial Statements
December 31, 1996
- --------------------------------------------------------------------------------
 
1. GENERAL
UBS  Bond Fund  (the 'Fund')  is a  diversified, no-load  mutual fund registered
under the Investment Company Act  of 1940. The Fund is  a series of UBS  Private
Investor  Funds, Inc. (the 'Company'), an open-end management investment company
organized as a corporation under Maryland law. At December 31, 1996, the Company
included two other  funds, UBS  U.S. Equity  Fund and  UBS International  Equity
Fund. These financial statements relate only to the Fund.
 
The  Fund  had no  operations prior  to April  2,  1996 other  than the  sale to
Signature Financial Group, Inc. of 250 shares of common stock for $25,000.
 
The Fund seeks to  achieve its investment  objective by investing  substantially
all  of  its  investable  assets  in the  UBS  Bond  Portfolio  of  UBS Investor
Portfolios Trust (the  'Portfolio'), an open-end  management investment  company
that has the same investment objective as that of the Fund.
 
Signature  Broker-Dealer Services, Inc. ('Signature'), a wholly-owned subsidiary
of Signature  Financial Group,  Inc.,  serves as  the Fund's  administrator  and
distributor.  Union Bank of  Switzerland, New York Branch  ('UBS') serves as the
fund services agent to the Fund.
 
The  financial  statements   of  the  Portfolio,   including  its  Schedule   of
Investments,  are included  elsewhere within this  report and should  be read in
conjunction with the Fund's financial statements.
 
2. SIGNIFICANT ACCOUNTING POLICIES
The preparation of  financial statements in  accordance with generally  accepted
accounting principles requires management to make estimates and assumptions that
affect  the reported amounts and disclosures in the financial statements. Actual
results could  differ  from  those estimates.  Significant  accounting  policies
followed by the Fund are as follows:
 
A.  INVESTMENT VALUATION -- The value of  the Fund's investment in the Portfolio
included in the accompanying  Statement of Assets  and Liabilities reflects  the
Fund's  proportionate beneficial  interest in  the net  assets of  the Portfolio
(14.3% at  December 31,  1996).  Valuation of  securities  by the  Portfolio  is
discussed  in Note 2A of the Portfolio's Notes to Financial Statements which are
included elsewhere in this report.
 
B.  INVESTMENT  INCOME,   EXPENSES  AND  REALIZED   AND  UNREALIZED  GAINS   AND
LOSSES  -- The  Fund records  its share of  the investment  income, expenses and
realized and unrealized gains  and losses recorded by  the Portfolio on a  daily
basis.  The investment  income, expenses and  realized and  unrealized gains and
losses are allocated daily to investors  of the Portfolio based upon the  amount
of their investment in the Portfolio.
 
C.  FEDERAL TAXES -- The  Fund's policy is to comply  with the provisions of the
Internal Revenue Code  applicable to regulated  investment companies,  including
the requirement to distribute substantially all of its taxable income, including
any  net realized capital gains on investment transactions, to its shareholders.
Accordingly, no provision for federal income or excise taxes is necessary.
 
D.  DIVIDENDS  AND  DISTRIBUTIONS  --  The  Fund  declares  dividends  from  net
investment  income to  shareholders of  record on  the day  of declaration. Such
dividends are declared daily and paid monthly. Net realized gains, if any,  will
be distributed at least annually. However, to the extent that net realized gains
of  the Fund can be  reduced by capital loss carryovers,  such gains will not be
distributed. Dividends and distributions are recorded on the ex-dividend date.
 
The amounts of dividends from net  investment income and distributions from  net
realized  gains are determined in accordance with federal income tax regulations
which may differ from generally accepted accounting principles. These 'book/tax'
differences are either considered temporary or permanent in

nature. To the extent  these differences are permanent  in nature, such  amounts
are  reclassified within the composition of  net assets based upon their federal
tax-basis treatment; temporary differences do not require reclassification.  For
the  fiscal  year  ended  December  31,  1996,  the  Fund  increased accumulated
undistributed net realized  gains by $6,044,  reduced accumulated  undistributed
net  investment income  by $4,838 and  decreased paid-in capital  by $1,206. Net
investment income, net realized gains and  net assets were not affected by  this
change.
 
E. DEFERRED ORGANIZATION EXPENSES -- Expenses incurred by the Fund in connection
with  its organization in the amount of $72,500 have been deferred and are being
amortized on a straight line basis over five years from the Fund's  commencement
of operations (April 2, 1996).
 
F.  OTHER --  The Fund  bears all  costs of  its operations  other than expenses
specifically assumed by Signature and UBS.  Expenses incurred by the Company  on
behalf of any two or more funds are allocated in proportion to the net assets of
each fund, except when allocations of direct expenses to each fund can otherwise
be  made fairly. Expenses directly attributable to the Fund are charged directly
to the Fund.
 
3. AGREEMENTS AND OTHER TRANSACTIONS WITH AFFILIATES
 
A. ADMINISTRATIVE SERVICES  AGREEMENT --  Under the terms  of an  Administrative
Services  Agreement with the Company,  Signature provides overall administrative
services and general office facilities.  As compensation for such services,  the
Company has agreed to pay Signature a fee, accrued daily and payable monthly, at
an  annual rate  of 0.05%  of the  Fund's first  $100 million  average daily net
assets and 0.025% of the next  $100 million average daily net assets.  Signature
does  not receive a fee  on average daily net assets  in excess of $200 million.
For the period April 2, 1996  (commencement of operations) through December  31,
1996, the administrative services fee amounted to $1,526.
 
B.  DISTRIBUTION  AGREEMENT  -- Under  the  terms of  a  Distribution Agreement,
Signature serves as the distributor of  Fund shares. Signature does not  receive
any additional fees for services provided pursuant to this agreement.
 
C.  SHAREHOLDER SERVICES  AGREEMENT -- The  Fund has entered  into a Shareholder
Services Agreement with UBS pursuant to  which UBS provides certain services  to
shareholders  of  the Fund.  The Fund  has agreed  to  pay UBS  a fee  for these
services, accrued daily and payable monthly, at  an annual rate of 0.25% of  the
average daily net assets of the Fund. For the period April 2, 1996 (commencement
of  operations) through December 31, 1996,  the shareholder service fee amounted
to $7,632, all of which was waived.
 
D. FUND SERVICES AGREEMENT -- Under the terms of a Fund Services Agreement  with
the  Company, UBS has  agreed to provide certain  administrative services to the
Fund. UBS  is not  entitled  to any  additional  compensation pursuant  to  this
agreement.
 
E.  EXPENSE  REIMBURSEMENTS --  UBS has  voluntarily agreed  to limit  the total
operating expenses of the Fund, including its share of the Portfolio's  expenses
and  excluding extraordinary expenses, to an annual  rate of 0.80% of the Fund's
average daily  net  assets.  For  the period  April  2,  1996  (commencement  of
operations)  through December  31, 1996,  UBS reimbursed  the Fund  for expenses
totaling $80,050 in connection with this voluntary limitation. UBS may modify or
discontinue this voluntary expense limitation at any time with 30 days'  advance
notice to the Fund.

To the Board of Directors and

In  our opinion, the  accompanying statement of assets  and liabilities, and the

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

UBS Bond Portfolio
Notes to Financial Statements
December 31, 1996
- --------------------------------------------------------------------------------
 
1. GENERAL
UBS  Bond  Portfolio  (the  'Portfolio'),  a  separate  series  of  UBS Investor
Portfolios Trust (the 'Trust'), is  registered under the Investment Company  Act
of  1940, as a diversified, open-end management investment company. The Trust is
organized as a trust under the laws of the State of New York.
 
The investment adviser of the Portfolio  is Union Bank of Switzerland, New  York
Branch  ('UBS').  Signature  Financial  Group (Grand  Cayman),  Ltd.  ('SFG'), a
wholly-owned  subsidiary  of  Signature  Financial  Group,  Inc.,  acts  as  the
Portfolio's administrator and placement agent.
 
2. SIGNIFICANT ACCOUNTING POLICIES
The preparation of financial statements in accordance with accounting principles
generally  accepted in the  United States requires  management to make estimates
and assumptions  that  affect  the  reported  amounts  and  disclosures  in  the
financial  statements.  Actual results  could differ  from those  estimates. The
following is  a  summary of  significant  accounting policies  followed  by  the
Portfolio in the preparation of its financial statements:
 
A.  INVESTMENT VALUATION  -- Debt securities  with a remaining  maturity of more
than 60 days are normally valued by  a pricing service approved by the Board  of
Trustees  (the 'Trustees'). Such  pricing service will  consider various factors
when arriving at  a valuation for  a security. Such  factors include yields  and
prices  of comparable securities, indications as  to values from dealers in such
securities and general  market conditions.  In the  event a  pricing service  is
unable to price a security, the security will be valued by taking the average of
the bid and ask prices as provided by a dealer in such security.
 
Debt  securities that mature  in 60 days  or less are  valued at amortized cost,
which approximates market value.  The amortized cost  method involves valuing  a
security  at its  cost on  the date of  purchase or,  in the  case of securities
purchased with more than 60 days until maturity, at their market value each  day
until  the  61st  day prior  to  maturity,  and thereafter  assuming  a constant
amortization to maturity of the difference  between the principal amount due  at
maturity and such valuation.
 
Securities or other assets for which market quotations are not readily available
are  valued at fair value in accordance with procedures established by and under
the general supervision of the Trustees.
 
B. FOREIGN CURRENCY TRANSLATION -- The  accounting records of the Portfolio  are
maintained  in  U.S.  dollars.  Assets,  including  investment  securities,  and
liabilities denominated in foreign currency are translated into U.S. dollars  at
the  prevailing rate of exchange at year end. Purchases and sales of securities,
income and expenses  are translated at  the prevailing rate  of exchange on  the
respective  dates  of such  transactions.  Gain/loss on  translation  of foreign
currency includes net exchange gains and losses, gains and losses on disposition
of foreign currency and adjustments to the amount of foreign taxes withheld.
 
The assets and liabilities are presented at the exchange rates and market values
at the close  of the year.  The changes in  net assets arising  from changes  in
exchange  rates and the changes  in net assets resulting  from changes in market
prices of securities  held at  year-end are not  separately presented.  However,
gains  and  losses from  certain foreign  currency  transactions are  treated as
ordinary income for U.S. Federal income tax purposes.
 
C. FORWARD FOREIGN CURRENCY  CONTRACTS -- The Portfolio  may enter into  forward
foreign  currency contracts  in connection  with planned  purchases or  sales of
securities or to hedge the U.S. dollar value of portfolio securities denominated
in a  particular  currency. The  Portfolio  could be  exposed  to risks  if  the
counterparties  to the contracts are unable to meet the terms of their contracts
and from unanticipated movements in the value of a foreign currency relative  to
the  U.S. dollar.  The forward  foreign currency  contracts are marked-to-market
daily using  the  daily  exchange  rate  of  the  underlying  currency  and  any

UBS Bond Portfolio
Notes to Financial Statements
December 31, 1996
- --------------------------------------------------------------------------------
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 year end to credit loss in the event of a counterparty's
failure to perform its obligations.
 
D.  ACCOUNTING FOR INVESTMENTS  -- Securities transactions  are accounted for on
trade date. Realized gains and losses on security transactions are determined on
the identified  cost  basis.  Interest  income,  adjusted  for  amortization  of
premiums and accretion of discounts on investments, is accrued daily.
 
E.  U.S. FEDERAL INCOME TAXES -- The Portfolio is considered a partnership under
the U. S.  Internal Revenue Code  (the 'Code').  As such, each  investor in  the
Portfolio  will be  taxed on  its share of  the Portfolio's  ordinary income and
capital gains. Accordingly, no provision for federal income taxes is  necessary.
It is intended that the Portfolio will be managed in such a way that an investor
will  be able to  satisfy the requirements  of the Code  applicable to regulated
investment companies.
 
F. DEFERRED  ORGANIZATION EXPENSES  --  Expenses incurred  by the  Portfolio  in
connection with its organization in the amount of $50,000 have been deferred and
are  being  amortized  on  a  straight  line  basis  over  five  years  from the
Portfolio's commencement of operations (April 2, 1996).
 
G. OTHER -- The Portfolio bears all costs of its operations other than  expenses
specifically assumed by UBS and SFG. Expenses incurred by the Trust on behalf of
any two or more portfolios are allocated in proportion to the net assets of each
portfolio,  except when  allocations of  direct expenses  to each  portfolio can
otherwise be made fairly.  Expenses directly attributable  to the Portfolio  are
charged directly to the Portfolio.
 
3. AGREEMENTS AND OTHER TRANSACTIONS WITH AFFILIATES
A.  INVESTMENT ADVISORY AGREEMENT -- The  Portfolio has retained the services of
UBS as  investment  adviser. UBS  makes  the Portfolio's  day-to-day  investment
decisions,  arranges for the  execution of portfolio  transactions and generally
manages the Portfolio's investments and operations. As compensation for  overall
investment  management services  the Trust has  agreed to pay  UBS an investment
advisory fee, accrued daily and payable monthly,  at an annual rate of 0.45%  of
the  Portfolio's  average  daily  net  assets.  For  the  period  April  2, 1996
(commencement of operations) through December  31, 1996, UBS voluntarily  agreed
to waive the entire investment advisory fee. Such waiver amounted to $131,348.
 
B.  ADMINISTRATIVE SERVICES  AGREEMENT -- Under  the terms  of an Administrative
Services Agreement with the Trust, SFG provides overall administrative  services
and  general office facilities  to the Portfolio and  the Trust. As compensation
for such  services,  the Portfolio  has  agreed  to pay  SFG  an  administrative
services  fee, accrued daily and payable monthly,  at an annual rate of 0.05% of
the Portfolio's average  daily net  assets. For the  period from  April 2,  1996
(commencement  of  operations)  through December  31,  1996,  the administrative
services fee amounted to $14,594.
 
C. EXCLUSIVE  PLACEMENT AGENT  AGREEMENT  -- Under  the  terms of  an  Exclusive
Placement  Agent Agreement with the Trust, SFG  has agreed to act as the Trust's
placement agent. SFG does not receive any additional fees for services  provided
pursuant to this agreement.

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

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

nature. To the extent  these differences are permanent  in nature, such  amounts
are  reclassified within the composition of  net assets based upon their federal
tax-basis treatment; temporary differences do not require reclassification.  For
the  fiscal  year  ended  December  31,  1996,  the  Fund  increased accumulated
undistributed  net   investment   income  by   $7,723,   decreased   accumulated
undistributed  net realized  gains by  $2,984 and  decreased paid-in  capital by
$4,739. Net  investment income,  net  realized gains  and  net assets  were  not
affected by this change.
 
E. DEFERRED ORGANIZATION EXPENSES -- Expenses incurred by the Fund in connection
with  its organization in the amount of $72,500 have been deferred and are being
amortized on a straight line basis over five years from the Fund's  commencement
of operations (April 2, 1996).
 
F.  OTHER --  The Fund  bears all  costs of  its operations  other than expenses
specifically assumed by Signature and UBS.  Expenses incurred by the Company  on
behalf of any two or more funds are allocated in proportion to the net assets of
each fund, except when allocations of direct expenses to each fund can otherwise
be  made fairly. Expenses directly attributable to the Fund are charged directly
to the Fund.
 
3. AGREEMENTS AND OTHER TRANSACTIONS WITH AFFILIATES
A. ADMINISTRATIVE SERVICES  AGREEMENT --  Under the terms  of an  Administrative
Services  Agreement with the Company,  Signature provides overall administrative
services and general office facilities.  As compensation for such services,  the
Company has agreed to pay Signature a fee, accrued daily and payable monthly, at
an  annual rate  of 0.05%  of the  Fund's first  $100 million  average daily net
assets and 0.025% of the next  $100 million average daily net assets.  Signature
does  not receive a fee  on average daily net assets  in excess of $200 million.
For the period April 2, 1996  (commencement of operations) through December  31,
1996, the administrative services fee amounted to $4,131.
 
B.  DISTRIBUTION AGREEMENT --  Under the terms of  a Distribution Agreement with
the Company, Signature serves as the distributor of Fund shares. Signature  does
not  receive  any  additional  fees  for  services  provided  pursuant  to  this
agreement.
 
C. SHAREHOLDER SERVICES  AGREEMENT -- The  Fund has entered  into a  Shareholder
Services  Agreement with UBS pursuant to  which UBS provides certain services to
shareholders of  the Fund.  The Fund  has  agreed to  pay UBS  a fee  for  these
services,  accrued daily and payable monthly, at  an annual rate of 0.25% of the
average daily net assets of the Fund. For the period April 2, 1996 (commencement
of operations) through December 31,  1996, the shareholder service fee  amounted
to $20,658, all of which was waived.
 
D.  FUND SERVICES AGREEMENT -- Under the terms of a Fund Services Agreement with
the Company, UBS has  agreed to provide certain  administrative services to  the
Fund.  UBS  is not  entitled  to any  additional  compensation pursuant  to this
agreement.
 
E. EXPENSE  REIMBURSEMENTS --  UBS has  voluntarily agreed  to limit  the  total
operating  expenses of the Fund, including its share of the Portfolio's expenses
and excluding extraordinary expenses. For the period April 2, 1996 (commencement
of operations) through December  26, 1996, the  Fund's total operating  expenses
were  limited to  an annual  rate of  1.40%. Effective  December 27,  1996, this
expense limitation was reduced to an annual rate of 0.95% of the Fund's  average
daily  net assets.  For the  period April  2, 1996  (commencement of operations)
through December 31, 1996, UBS reimbursed the Fund for expenses totaling $52,899
in connection  with  this  voluntary  limitation.  The  Adviser  may  modify  or
discontinue  this voluntary expense limitation at any time with 30 days' advance
notice to the Fund.

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

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

investment advisory fee amounted  to $199,112. UBS  voluntarily agreed to  waive
$185,273 of this amount.
 
B.  ADMINISTRATIVE SERVICES  AGREEMENT -- Under  the terms  of an Administrative
Services Agreement with the Trust, SFG provides overall administrative  services
and  general office facilities  to the Portfolio and  the Trust. As compensation
for such  services,  the Portfolio  has  agreed  to pay  SFG  an  administrative
services  fee, accrued daily and payable monthly,  at an annual rate of 0.05% of
the Portfolio's  average  daily  net  assets.  For  the  period  April  2,  1996
(commencement  of  operations)  through December  31,  1996,  the administrative
services fee amounted to $11,712.
 
C. EXCLUSIVE  PLACEMENT AGENT  AGREEMENT  -- Under  the  terms of  an  Exclusive
Placement  Agent Agreement with the Trust, SFG  has agreed to act as the Trust's
placement agent. SFG does not receive any additional fees for services  provided
pursuant to this agreement.
 
4. PURCHASES AND SALES OF INVESTMENTS
For  the period April 2, 1996  (commencement of operations) through December 31,
1996,  purchases  and  sales  of  investment  securities,  excluding  short-term
investments, aggregated $45,726,468 and $11,686,401, 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  International  Equity
Portfolio (the 'Portfolio') (one of the portfolios constituting the UBS Investor
Portfolios  Trust) at December 31, 1996, and  the results of its operations, the
changes in its net assets and the  financial highlights for the period April  2,
1996  (commencement of operations) through December 31, 1996, in conformity with
generally accepted accounting principles in  the United States. These  financial
statements  and  financial  highlights  (hereafter  referred  to  as  'financial
statements')  are  the  responsibility   of  the  Portfolio's  management;   our
responsibility  is to express an opinion  on these financial statements based on
our audit. We conducted  our audit of these  financial statements in  accordance
with  generally accepted auditing  standards in the  United States which require
that we plan and perform the audit to obtain reasonable assurance about  whether
the  financial statements are  free of material  misstatement. An audit includes
examining, on a test basis, evidence  supporting the amounts and disclosures  in
the   financial  statements,  assessing  the   accounting  principles  used  and
significant estimates made by management,  and evaluating the overall  financial
statement  presentation. We believe that  our audit, which included confirmation
of securities at  December 31,  1996 by  correspondence with  the custodian  and
brokers,   and  the   application  of  alternative   auditing  procedures  where
confirmations from brokers were not received provides a reasonable basis for the
opinion expressed above.

UBS U.S. Equity Fund
Notes to Financial Statements
December 31, 1996
- --------------------------------------------------------------------------------
 
1. GENERAL
UBS  U.S.  Equity  Fund  (the  'Fund') is  a  diversified,  no-load  mutual fund
registered under the Investment Company Act of 1940. The Fund is a series of UBS
Private Investor Funds, Inc. (the 'Company'), an open-end management  investment
company organized as a corporation under Maryland law. At December 31, 1996, the
Company  included two  other funds, UBS  Bond Fund and  UBS International Equity
Fund. These financial statements relate only to the Fund.
 
The Fund  had no  operations prior  to  April 2,  1996 other  than the  sale  to
Signature Financial Group, Inc. of 250 shares of common stock for $25,000.
 
The  Fund seeks to  achieve its investment  objective by investing substantially
all of its investable assets  in the UBS U.S.  Equity Portfolio of UBS  Investor
Portfolios  Trust (the  'Portfolio'), an open-end  management investment company
that has the same investment objective as that of the Fund.
 
Signature Broker-Dealer Services, Inc. ('Signature'), a wholly-owned  subsidiary
of  Signature  Financial Group,  Inc., serves  as  the Fund's  administrator and
distributor. Union Bank of  Switzerland, New York Branch  ('UBS') serves as  the
fund services agent to the Fund.
 
The   financial  statements  of   the  Portfolio,  including   its  Schedule  of
Investments, are included  elsewhere within this  report and should  be read  in
conjunction with the Fund's financial statements.
 
2. SIGNIFICANT ACCOUNTING POLICIES
The  preparation of financial  statements in accordance  with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts and disclosures in the financial statements.  Actual
results  could  differ  from those  estimates.  Significant  accounting policies
followed by the Fund are as follows:
 
A. INVESTMENT VALUATION -- The value  of the Fund's investment in the  Portfolio
included  in the accompanying  Statement of Assets  and Liabilities reflects the
Fund's proportionate  beneficial interest  in the  net assets  of the  Portfolio
(37.3%  at  December 31,  1996).  Valuation of  securities  by the  Portfolio is
discussed in Note 2A of the Portfolio's Notes to Financial Statements which  are
included elsewhere in this report.
 
B.   INVESTMENT  INCOME,  EXPENSES   AND  REALIZED  AND   UNREALIZED  GAINS  AND
LOSSES -- The  Fund records  its share of  the investment  income, expenses  and
realized  and unrealized gains and  losses recorded by the  Portfolio on a daily
basis. The investment  income, expenses  and realized and  unrealized gains  and
losses  are allocated daily to investors of  the Portfolio based upon the amount
of their investment in the Portfolio.
 
C. FEDERAL TAXES -- The  Fund's policy is to comply  with the provisions of  the
Internal  Revenue Code  applicable to regulated  investment companies, including
the requirement to distribute substantially all of its taxable income, including
any net realized capital gains on investment transactions, to its  shareholders.
Accordingly, no provision for federal income or excise taxes is necessary.
 
D.  DIVIDENDS  AND  DISTRIBUTIONS  --  The  Fund  declares  dividends  from  net
investment income to  shareholders of  record on  the day  of declaration.  Such
dividends  are declared and paid  annually. Net realized gains,  if any, will be
distributed at least annually. However, to the extent that net realized gains of
the Fund can  be reduced  by capital  loss carryovers,  such gains  will not  be
distributed. Dividends and distributions are recorded on the ex-dividend date.
 
The  amounts of dividends from net  investment income and distributions from net
realized gains are determined in accordance with federal income tax  regulations
which may differ from generally accepted accounting principles. These 'book/tax'
differences are either considered temporary or permanent in
 

<PAGE>
UBS U.S. Equity Fund
Notes to Financial Statements

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

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

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

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

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 U.S. Equity Portfolio (the
'Portfolio') (one  of the  portfolios constituting  the UBS  Investor  Portfolio
Trust)  at December 31, 1996, and the  results of its operations, the changes in
its net  assets  and the  financial  highlights for  the  period April  2,  1996
(commencement  of  operations) through  December  31, 1996,  in  conformity with
generally accepted accounting principles in  the United States. These  financial
statements  and  financial  highlights  (hereafter  referred  to  as  'financial
statements')  are  the  responsibility   of  the  Portfolio's  management;   our
responsibility  is to express an opinion  on these financial statements based on
our audit. We conducted  our audit of these  financial statements in  accordance
with  generally accepted auditing  standards in the  United States which require
that we plan and perform the audit to obtain reasonable assurance about  whether
the  financial statements are  free of material  misstatement. An audit includes
examining, on a test basis, evidence  supporting the amounts and disclosures  in
the   financial  statements,  assessing  the   accounting  principles  used  and
significant estimates made by management,  and evaluating the overall  financial
statement  presentation. We believe that  our audit, which included confirmation
of securities at  December 31,  1996 by  correspondence with  the custodian  and
brokers, provides a reasonable basis for the opinion expressed above.

        trust, other enterprise, or employee benefit plan.
 
          (5) 'Party' includes a person who was, is, or is threatened to be made
     a named defendant or respondent in a proceeding.
 
          (6) 'Proceeding' means any threatened, pending or completed action,
     suit or proceeding, whether civil, criminal, administrative, or
     investigative.
 
          (b)(1) A corporation may indemnify any director made a party to any
     proceeding by reason of service in that capacity unless it is established
     that:
 
             (i) the act or omission of the director was material to the matter
        giving rise to the proceeding; and
 
             1. Was committed in bad faith; or
 
             2. Was the result of active and deliberate dishonesty; or
 
             (ii) The director actually received an improper personal benefit in
        money, property, or services; or
 
             (iii) In the case of any criminal proceeding, the director had
        reasonable cause to believe that the act or omission was unlawful.
 
          (2)(i) Indemnification may be against judgments, penalties, fines,
     settlements, and reasonable expenses actually incurred by the director in
     connection with the proceeding.
 
          (ii) However, if the proceeding was one by or in the right of the
     corporation, indemnification may not be made in respect of any proceeding
     in which the director shall have been adjudged to be liable to the
     corporation.
 
          (3)(i) The termination of any proceeding by judgment, order, or
     settlement does not create a presumption that the director did not meet the
     requisite standard of conduct set forth in this subsection.

          (ii) The termination of any proceeding by conviction, or a plea of
     nolo contendere or its equivalent, or an entry of an order of probation
     prior to judgment, creates a rebuttable presumption that the director did
     not meet that standard of conduct.
 
          (c) A director may not be indemnified under subsection (B) of this
     section in respect of any proceeding charging improper personal benefit to
     the director, whether or not involving action in the director's official
     capacity, in which the director was adjudged to be liable on the basis that
     personal benefit was improperly received.
 
          (d) Unless limited by the charter:
 
             (1) A director who has been successful, on the merits or otherwise,
        in the defense of any proceeding referred to in subsection (B) of this
        section shall be indemnified against reasonable expenses incurred by the
        director in connection with the proceeding.
 
             (2) A court of appropriate jurisdiction upon application of a
        director and such notice as the court shall require, may order
        indemnification in the following circumstances:
 
                (i) If it determines a director is entitled to reimbursement
           under paragraph (1) of this subsection, the court shall order
           indemnification, in which case the director shall be entitled to
           recover the expenses of securing such reimbursement; or
 
                (ii) If it determines that the director is fairly and reasonably
           entitled to indemnification in view of all the relevant
           circumstances, whether or not the director has met the standards of
           conduct set forth in subsection (b) of this section or has been
           adjudged liable under the circumstances described in subsection (c)
           of this section, the court may order such indemnification as the
           court shall deem proper. However, indemnification with respect to any
           proceeding by or in the right of the corporation or in which
           liability shall have been adjudged in the circumstances described in
           subsection (c) shall be limited to expenses.
 
             (3) A court of appropriate jurisdiction may be the same court in
        which the proceeding involving the director's liability took place.
 
             (e)(1) Indemnification under subsection (b) of this section may not
        be made by the corporation unless authorized for a specific proceeding
        after a determination has been made that indemnification of the director
        is permissible in the circumstances because the director has met the
        standard of conduct set forth in subsection (b) of this section.
 
             (2) Such determination shall be made:
 
                (i) By the board of directors by a majority vote of a quorum
           consisting of directors not, at the time, parties to the proceeding,
           or, if such a quorum cannot be obtained, then by a majority vote of a
           committee of the board consisting solely of two or more directors
           not, at the time, parties to such proceeding and who were duly
           designated to act in the matter by a majority vote of the full board
           in which the designated directors who are parties may participate;
 
                (ii) By special legal counsel selected by the board of directors
           or a committee of the board by vote as set forth in subparagraph (i)
           of this paragraph, or, if the requisite quorum of the full board
           cannot be obtained therefor and the committee cannot be established,
           by a majority vote of the full board in which director [SIC] who are
           parties may participate; or
 
                (iii) By the shareholders.
 
             (3) Authorization of indemnification and determination as to
        reasonableness of expenses shall be made in the same manner as the
        determination that indemnification is permissible. However, if the
        determination that indemnification is permissible is made by special
        legal counsel, authorization of indemnification and determination as to
        reasonableness of expenses shall be made in the manner specified in
        subparagraph (ii) of paragraph (2) of this subsection for selection of
        such counsel.
 
             (4) Shares held by directors who are parties to the proceeding may
        not be voted on the subject matter under this subsection.
 
             (f)(1) Reasonable expenses incurred by a director who is a party to
        a proceeding may be paid or reimbursed by the corporation in advance of
        the final disposition of the proceeding upon receipt by the corporation
        of:
 
                (i) A written affirmation by the director of the director's good
           faith belief that the standard of conduct necessary for
           indemnification by the corporation as authorized in this section has
           been met; and
 
                (ii) A written undertaking by or on behalf of the director to
           repay the amount if it shall ultimately be determined that the
           standard of conduct has not been met.
 
             (2) The undertaking required by subparagraph (ii) of paragraph (1)
        of this subsection shall be an unlimited general obligation of the
        director but need not be secured and may be accepted without reference
        to financial ability to make the repayment.
 
             (3) Payments under this subsection shall be made as provided by the
        charter, bylaws, or contract or as specified in subsection (e) of this
        section.
 
             (g) The indemnification and advancement of expenses provided or
        authorized by this section may not be deemed exclusive of any other
        rights, by indemnification or otherwise, to which a director may be
        entitled under the charter, the bylaws, a resolution of shareholders or
        directors, an agreement or otherwise, both as to action in an official
        capacity and as to action in another capacity while holding such office.
 
             (h) This section does not limit the corporation's power to pay or
        reimburse expenses incurred by a director in connection with an
        appearance as a witness in a proceeding at a time when the director has
        not been made a named defendant or respondent in the proceeding.
 
             (i) For purposes of this section:
 
                (1) The corporation shall be deemed to have requested a director
           to serve an employee benefit plan where the performance of the
           director's duties to the corporation also imposes duties on, or
           otherwise involves services by, the director to the plan or
           participants or beneficiaries of the plan;
 
                (2) Excise taxes assessed on a director with respect to an
           employee benefit plan pursuant to applicable law shall be deemed
           fines; and
 
                (3) Action taken or omitted by the director with respect to an
           employee benefit plan in the performance of the director's duties for
           a purpose reasonably believed by the director to be in the interest
           of the participants and beneficiaries of the plan shall be deemed to
           be for a purpose which is not opposed to the best interests of the
           corporation.
 
             (j) Unless limited by the charter:
 
                (1) An officer of the corporation shall be indemnified as and to
           the extent provided in subsection (d) of this section for a director
           and shall be entitled, to the same extent as a director, to seek
           indemnification pursuant to the provisions of subsection (d);
 
                (2) A corporation may indemnify and advance expenses to an
           officer, employee, or agent of the corporation to the same extent
           that it may indemnify directors under this section; and
 
                (3) A corporation, in addition, may indemnify and advance
           expenses to an officer, employee, or agent who is not a director to
           such further extent, consistent with law, as may be provided by its
           charter, bylaws, general or specific action of its board of directors
           or contract.
 
             (k)(1) A corporation may purchase and maintain insurance on behalf
        of any person who is or was a director, officer, employee, or agent of
        the corporation, or who, while a director, officer, employee, or agent
        of the corporation, is or was serving at the request of the corporation
        as a director, officer, partner, trustee, employee, or agent of another
        foreign or domestic corporation, partnership, joint venture, trust,
        other enterprise, or employee benefit plan against any liability
        asserted against and incurred by such person in any such capacity or
        arising out of such person's position, whether or not the corporation
        would have the power to indemnify against liability under the provisions
        of this section.
 
             (2) A corporation may provide similar protection, including a trust
        fund, letter of credit, or surety bond, not inconsistent with this
        section.
 
             (3) The insurance or similar protection may be provided by a
        subsidiary or an affiliate of the corporation.
 
             (l) Any indemnification of, or advance of expenses to, a director
        in accordance with this section, if arising out of a proceeding by or in
        the right of the corporation, shall be reported in writing to the
        shareholders with the notice of the next stockholders' meeting or prior
        to the meeting.'
 
     Article SEVENTH of the Company's Articles of Incorporation provides:
 
          'To the fullest extent permitted by Maryland statutory or decisional
     law, as amended or interpreted, and the Investment Company Act of 1940, no
     director or officer of the Corporation shall be personally liable to the
     Corporation or its stockholders for money damages; provided, however, that
     nothing herein shall be construed to protect any director or officer of the
     Corporation against any liability to the Corporation or its security
     holders to which such person would otherwise be subject by reason of
     willful misfeasance, bad faith, gross negligence or reckless disregard of
     the duties involved in the conduct of such person's office. No amendment of
     the Corporation's charter or repeal of any of its provisions shall limit or
     eliminate the limitation of liability provided to directors and officers
     hereunder with respect to any act or omission occurring prior to such
     amendment or repeal.'
 
     Article EIGHTH of the Company's Articles of Incorporation provides:
 
          'The Corporation shall indemnify (i) its directors and officers,
     whether serving the Corporation or at its request any other entity, to the
     full extent required or permitted by Maryland statutory and decisional law,
     now or hereafter in force, including the advance of expenses under the
     procedures and to the full extent permitted by law, and (ii) other
     employees and agents to such extent as shall be authorized by the Board of
     Directors or the Bylaws and as permitted by law. Nothing contained herein
     shall be construed to protect any director, officer, employee or agent of
     the Corporation against any liability to the Corporation or its security
     holders to which such person would otherwise be subject by reason of
     willful misfeasance, bad faith, gross negligence or reckless disregard of
     the duties involved in the conduct of such person's office. The foregoing
     rights of indemnification shall not be exclusive of any other rights to
     which those seeking indemnification may be entitled. The Board of Directors
     may take such action as is necessary to carry out these indemnification
     provisions and is expressly empowered to adopt, approve and amend from time
     to time such Bylaws, resolutions or contracts implementing such provisions
     or such further indemnification arrangements as may be permitted by law. No
     amendment of the Corporation's charter or repeal of any of its provisions
     shall limit or eliminate the right of indemnification provided hereunder
     with respect to acts or omissions occurring prior to such amendment or
     repeal.'
 
     Article FOURTH of the Company's Bylaws provides:
 
          Insurance. The Corporation may purchase and maintain insurance on
     behalf of any person who is or was a director or officer of the Corporation
     or serves or served at the request of the Corporation any other enterprise
     as a director or officer, whether or not the Corporation would have power
     to indemnify such person.
 
                            ------------------------
 
     Reference is made to Article 4 of the Company's Distribution Agreement.
 
     The Company, its Directors and officers are insured against certain
expenses in connection with the defense of claims, demands, action's suits or
proceedings, and certain liabilities that might be imposed as a result of such
actions, suits or proceedings.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933, as amended (the 'Securities Act'), may be permitted to Directors,
officers and controlling persons of the Company and the principal underwriter
pursuant to the foregoing provisions or otherwise, the Company has been advised
that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Company of expenses
incurred or paid by a Director, officer, or controlling person of the Company
and the principal underwriter in connection with the successful defense of any
action, suit or proceeding) is asserted against the Company by such Director,
officer or controlling person or principal underwriter in connection with the
shares being registered, the Company will, unless in the opinion of its counsel
the matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act and will be governed by
the final adjudication of such issue.
