                               Money Market Fund

                            Treasury Securities Fund
    1285 AVENUE OF THE AMERICAS   NEW YORK, NEW YORK 10019   (800) 647-1568
    
 
Liquid  Institutional Reserves (the  'Trust') is a  no-load, open-end investment
company offering shares in three separate, diversified, money market funds  (the
'Funds').  Each Fund seeks high current income to the extent consistent with the
preservation of capital and the maintenance of liquidity through investments  in
high quality, short term, U.S. dollar denominated money market instruments.
 
      The  Money Market Fund invests in a broad array of obligations of U.S. and
      foreign issuers and repurchase agreements.
 
      The Government Securities  Fund invests  in certain  securities issued  or
      guaranteed  as  to  principal and  interest  by the  U.S.  Government, its
      agencies, authorities or instrumentalities, the interest income from which
      is generally exempt from state income taxation.
 
      The Treasury Securities Fund invests  exclusively in securities issued  by
      the U.S. Treasury, which are supported by the full faith and credit of the
      United States.
 
An  investment in a  Fund is not  insured or guaranteed  by the U.S. Government.
Each Fund attempts  to maintain a  stable net  asset value of  $1.00 per  share,
although there can be no assurance that it will be able to do so at all times.
 
Each  Fund offers investors the  choice of investing in  two separate classes of
shares   representing   equal,   pro   rata   interests   in   its    investment
portfolio   --  'Institutional'  shares  and  'Financial  Intermediary'  shares.
Institutional shares  in  each  of  the Funds  are  available  for  purchase  by
institutional  investors. Financial Intermediary shares in each of the Funds are
available for  purchase by  banks  and other  financial intermediaries  for  the
benefit  of their customers and bear all  fees payable by the Funds to financial
intermediaries for certain  services they  provide to the  beneficial owners  of
these shares.
 
This  Prospectus briefly  sets forth  certain information  about the  Trust that
investors should  know before  investing.  Investors are  advised to  read  this
Prospectus  and retain it for future reference. Additional information about the
Trust, contained in a Statement of Additional Information dated the same date as
this Prospectus, has been filed with the Securities and Exchange Commission (the
'SEC') and is  available to investors  without charge by  calling the  telephone
number  set forth above. The Statement of Additional Information is incorporated
in its entirety by reference into this Prospectus. Shareholder inquiries may  be
directed to the Trust at the above address.
- --------------------------------------------------------------------------------
 
   THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES
     AND  EXCHANGE COMMISSION OR ANY  STATE SECURITIES COMMISSION NOR HAS
       THE SECURITIES AND EXCHANGE  COMMISSION OR ANY STATE  SECURITIES
         COMMISSION  PASSED  UPON THE  ACCURACY  OR ADEQUACY  OF THIS
              PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
                               CRIMINAL OFFENSE.

                                   FEE TABLE
 
Each  Fund offers  two separate  classes of  shares --  Institutional shares and
Financial Intermediary shares. Shares  of each class  represent equal, pro  rata
interests  in the Fund and accrue daily dividends in the same manner except that
Financial Intermediary  shares  bear  fees  payable by  the  Fund  to  financial
intermediaries  for  services they  provide to  the  beneficial owners  of these
shares. In  addition, financial  intermediaries may  directly charge  beneficial
owners of Financial Intermediary shares with fees relating to their investments,
which  are required to be  disclosed to those owners  by the intermediaries. See
'Management  of  the  Trust  --  Financial  Intermediaries'  and  'Purchase  and
Redemption  of Shares --  Other Matters.' Shares  of the Funds  are sold without
imposition of any sales charge, deferred  sales charge or any other  transaction
fee.

You  would pay the following expenses on a $1,000 investment,

     The   purpose  of  the  foregoing  table   is  to  assist  an  investor  in
understanding the various  costs and expenses  that an investor  in a Fund  will
bear  directly or  indirectly but should  not be considered  a representation of
past or  future  expenses or  rate  of return.  With  respect to  the  Financial
Intermediary shares, each Fund's 'other expenses' are based on estimates for the
Trust's  current fiscal year.  Expenses associated with  distributing the Funds'
shares are borne by the Trust's distributor out of its own resources and are not
borne directly or indirectly by shareholders. For more complete descriptions  of
the various costs and expenses, see 'Management of the Trust' in this Prospectus
and  'Investment Advisory  and Other  Services' in  the Statement  of Additional
Information.
 
   
      *At the  date of  this Prospectus,  no Financial  Intermediary shares  are
outstanding.
    
 
   
     [**Expense  table  and  the example  reflect  an agreement  by  the Trust's
investment adviser and adminstrator to reduce or otherwise limit the expenses of
each Fund, on an annualized basis, to .35% and .60% of each Fund's average daily
net assets in respect of Institutional shares and Financial Intermediary shares,
respectively. The information in the fee table set forth above has been restated
because, during the fiscal  year ended April 30,  1995, the Treasury  Securities
Fund

actually paid management fees in the amount of    % of its average net assets as
a  result of voluntary fee waivers by the Trust's manager. In the absence of the
agreement  described  in  the  first  sentence  of  this  note,  the  Government
Securities  Fund's and Treasury Securities Fund's total operating expenses would
have been      %  and      %,  respectively,  of their  average net  assets  for
Institutional  shares and would have been    % and     %, respectively, of their
average net assets  in respect  of Financial Intermediary  shares. Without  this
agreement, under the assumptions set forth in the example above, the expenses on
a  $1,000 investment in  the Government Securities  Fund and Treasury Securities
Fund at the end of one, three, five and ten years would have been $  , $  ,  $

it  will waive its fees or reimburse expenses in the current fiscal year, except
to the extent necessary  to comply with its  total expense limitation  agreement
described in the first sentence of this note.]

The Funds                   Each  Fund seeks high current income to the  extent consistent with the preservation of capital
                            and the  maintenance  of liquidity  through  investments in  a  diversified portfolio  of  high
                            quality, short term, U.S. dollar denominated money market instruments.
                            The  Money Market Fund invests in securities issued  or guaranteed as to principal and interest
                             by the  U.S.  Government,  its  agencies,  authorities  and  instrumentalities,  high  quality
                             obligations  of U.S. and foreign  banks, high quality commercial  paper and other high quality
                             obligations of U.S. and foreign companies and foreign governments and repurchase agreements.
                            The Government Securities Fund invests in securities  issued or guaranteed as to principal  and
                             interest  by  the U.S.  Government and  its agencies,  authorities and  instrumentalities, the
                             interest income from which is generally exempt from state income taxation.
                            The Treasury Securities  Fund invests exclusively  in securities issued  by the U.S.  Treasury,
                             which are supported by the full faith and credit of the United States.

Benefits of                 Mutual  funds,  such  as  the  Trust,  are  flexible  investment  tools  that  are increasingly
Investing                   popular -- for very sound reasons. The Trust offers investors the following important benefits:
in the Funds                Funds Designed For Institutions
                              The Funds are designed primarily for institutions  as an economical and convenient means  for
                             the  investment of short term funds that they hold for their own account or hold or manage for
                             others. These institutions  include corporations, banks,  trust companies, investment  bankers
                             and  brokers,  insurance companies,  investment counsellors,  pension funds,  employee benefit
                             plans, law firms, trusts, estates and educational, religious and charitable organizations. See
                             'Purchase and Redemption of Shares' and 'Management of the Trust -- Financial Intermediaries.'
 
                            Professional Management
                              By pooling the funds of many investors, each Fund enables shareholders to obtain the benefits
                             of full-time professional  management and a  degree of diversification  of investment that  is
                             beyond  the means  of most  investors. The Funds'  investment adviser  reviews the fundamental
                             characteristics of far more securities  than can a typical  investor and may employ  portfolio
                             management   techniques  that  frequently  are  not  used  by  many  institutional  investors.
                             Additionally, the larger denominations of securities in  which the Funds invest may result  in
                             better overall prices for the investments. See 'Investment Objective and Policies.'

                            Transaction Savings
                             By  investing in a Fund, a shareholder is able to acquire ownership in a diversified portfolio
                             of securities without paying the  higher transaction costs associated  with a series of  small
                             securities purchases.
 
                            Convenience
                              Fund   shareholders  are  relieved  of  the  administrative  and  recordkeeping  burdens  and
                             coordination of maturities normally associated with direct ownership of securities. Owners  of
                             Financial  Intermediary shares receive various  services from financial intermediaries through
                             which they acquire and hold their shares. See 'Purchase and Redemption of Shares' and 'Manage-
                             ment of the Trust -- Financial Intermediaries.'
 
                            Quality
                              All securities  in  which each  Fund  invests are  determined  to be  of  high quality  by  a
                             nationally  recognized rating organization, or  determined to be of  comparable quality by the
                             Trust's investment adviser acting  under the supervision  of the Board of  Trustees if not  so
                             rated,  and  also are  determined to  present minimal  credit risks.  Any purchase  of unrated
                             securities or securities that  are rated only by  a single rating agency  must be approved  or
                             ratified  by  the  Trustees. See  'Investment  Objective  and Policies  --  Certain Investment
                             Policies -- Portfolio Quality and Maturity.'
 
                            Liquidity
                              The Funds'  convenient purchase  and redemption  procedures provide  shareholders with  ready
                             access  to their money  and reduce the delays  frequently involved in  the direct purchase and
                             sale of securities. See 'Purchase and Redemption of Shares.'
 
                            Exchange Privilege
                              Shareholders of a Fund may exchange all or part of their shares for shares of the same  class
                             of  either of the other Funds in the Trust. See 'Purchase and Redemption of Shares -- Exchange

Shares                      Each Fund proposes to offer investors the choice of investing in two separate classes of shares
                            representing pro rata interests in its investment portfolio.
                            Institutional shares in each Fund are available for purchase by institutional investors.

Risk Factors                The Money Market  Fund may invest  in U.S.  dollar denominated securities  of foreign  issuers,
                            which  may present a greater degree of risk than investments in securities of domestic issuers.
                            The Fund may also enter into repurchase agreements. In the event of the bankruptcy of the other
                            party to a repurchase agreement  or its failure to honor  its obligations thereunder, the  Fund
                            could  suffer losses,  including loss  of interest on  or principal  of the  security and costs
                            associated with  delay  and enforcement  of  its rights  under  the repurchase  agreement.  See

 * As of  the date  of this  Prospectus, no  Financial Intermediary  shares  are
   outstanding.  Accordingly, yield  and average  portfolio maturity information
   for the  Financial  Intermediary  shares  are  not  being  reported  for  the
   seven-day periods ended April 30, 1995 and August 1, 1995.
    
 
     From  time to time,  each Fund advertises its  current yields and effective
yields for its  classes of shares.  The current yield  of a Fund  refers to  the
income  generated by an  investment in the  Fund over a  seven-day period, which
period will be stated in the advertisement. This income is then annualized; that
is, the amount of income generated by the investment during that week is assumed
to be generated each week over a 52-week period and is shown as a percentage  of
the   investment.  The  effective  yield   is  calculated  similarly  but,  when
annualized, the income  earned by an  investment in  the Fund is  assumed to  be
reinvested.  The effective yield will be  slightly higher than the current yield
because of the compounding effect of this assumed reinvestment.
 
     Investors should note that  the investment results of  a Fund are based  on
historical  performance  and will  fluctuate over  time.  Any presentation  of a
Fund's current yields  or effective yields  for any prior  period should not  be
considered  a representation  of what  an investment may  earn or  what a Fund's
current yields or effective yields may be in any future period.
 
     Current  yield   and  effective   yield  are   calculated  separately   for
Institutional  shares  and  Financial  Intermediary  shares.  Since  holders  of
Financial Intermediary shares bear all service fees for the services rendered by
financial intermediaries, the net yield on Financial Intermediary shares can  be
expected  at any given time to be approximately .25% lower than the net yield on
Institutional shares  and any  additional fees  directly assessed  by  financial
intermediaries  will have the effect of  further reducing the net yield realized
by a beneficial owner of Financial Intermediary shares.
 
     Performance data for the Funds in reports and promotional literature may be
compared to: (i) other mutual funds tracked by IBC/Donoghue's Money Fund  Report
and Lipper Analytical Services, widely used independent research firms that rank
mutual  funds  by  overall  performance, investment  objectives  and  assets, or
tracked by other services, companies,  publications or persons that rank  mutual
funds  on the  basis of  overall performance  or other  criteria; (ii) unmanaged
indices so that investors may compare the  Funds' results with those of a  group
of  unmanaged securities widely  regarded by investors  as representative of the
securities markets in general; and (iii) the Consumer Price Index, an  inflation
measure. Promotional and advertising literature also may refer to discussions of
the  Funds and comparative mutual fund  data and ratings reported in independent
periodicals.

                       INVESTMENT OBJECTIVE AND POLICIES
 
The investment objective  of each Fund  is to  earn high current  income to  the
extent  consistent  with  the preservation  of  capital and  the  maintenance of
liquidity through investments in a diversified portfolio of high quality,  short
term, U.S. dollar denominated money market instruments.
 
MONEY MARKET FUND
 
The  Money  Market Fund  pursues  its objective  by  investing in  the following
instruments:
 
           Securities issued or guaranteed as  to principal and interest by  the
           U.S.  Government,  its  agencies,  authorities  or  instrumentalities
           ('U.S. Government securities').
 
           High quality obligations  issued or guaranteed  by U.S. banks  having
           more  than  $1  billion in  total  assets  at the  time  of purchase,
           including  certificates  of  deposit,   fixed  time  deposits,   loan
           participation interests, commercial paper and bankers' acceptances.
 
           High  quality  U.S. dollar  denominated obligations,  including fixed
           time deposits, issued or guaranteed  by foreign banks, U.S.  branches
           of  foreign banks  (Yankee obligations), foreign  branches of foreign
           banks and foreign branches or subsidiaries of U.S. banks  (Eurodollar
           obligations)  having more than $1 billion in total assets at the time
           of purchase. These bank obligations may be general obligations of the
           parent bank or may be limited to  the issuing branch by the terms  of
           the specific obligation or by government regulation.
 
   
           Commercial  paper,  including  variable amount  master  demand notes,
           issued or  guaranteed by  U.S.  or foreign  corporations,  commercial
           banks  or other entities,  that at the  time of purchase  is rated at
           least A-1 by Standard & Poor's Ratings Group ('S&P'), P-1 by  Moody's
           Investors  Service,  Inc.  ('Moody's')  or  F-1  by  Fitch  Investors
           Services, Inc. ('Fitch').
    
 
           Unrated notes, paper or other  instruments that are determined to  be
           of comparable high quality.
 
           Other   high   quality,  short   term  obligations,   including  loan
           participation interests,  issued or  guaranteed  by U.S.  or  foreign
           corporations or other entities.
 
           High quality obligations of the International Bank for Reconstruction
           and Development and other supranational entities.
 
           High quality obligations, limited to commercial paper and other short
           term  notes, issued  or guaranteed by  the governments  of the United
           Kingdom,  France,   Germany,   Belgium,   the   Netherlands,   Italy,
           Switzerland,  Denmark,  Norway,  Austria,  Finland,  Spain,  Ireland,
           Sweden, Australia, New Zealand, Japan and Canada.
 
           High quality asset-backed securities, including interests in pools of
           assets such  as motor  vehicle installment  purchase obligations  and
           credit card receivables.
 
           Repurchase agreements.

     The  Fund may acquire  any of these  securities on a  forward commitment or
when-issued basis. The shares of the Fund  are not insured or guaranteed by  the
U.S. Government.
 
TREASURY SECURITIES FUND
 
The  Treasury Securities Fund pursues its  objective by limiting its investments
to securities issued by  the U.S. Treasury.  The Fund may  acquire any of  these
securities on a forward commitment or when-issued basis. The Fund will not enter
into repurchase agreements. The shares of the Fund are not insured or guaranteed
by the U.S. Government.
 
GOVERNMENT SECURITIES FUND
 
The  Government  Securities  Fund pursues  its  objective by  investing  in U.S.
Government securities, the interest income  from which is generally exempt  from
state  income taxation. The Fund intends  to emphasize investments in securities
eligible for  this  exemption  in  the  maximum  number  of  states.  Securities
generally  eligible for this exemption include those issued by the U.S. Treasury
and those issued by  certain agencies, authorities  or instrumentalities of  the
U.S. Government, including the Federal Home Loan Bank, Federal Farm Credit Banks
Funding  Corp. and the Student Loan  Marketing Association. Each investor should
consult its own  tax advisor to  determine whether distributions  from the  Fund
derived from interest on these obligations are exempt from state income taxation
in  the investor's own  state. The Fund intends  to invest all  of its assets in
securities  with  these  characteristics.  Under  extraordinary   circumstances,
however, such as when securities with those characteristics are unavailable, the
Fund  may temporarily hold  cash or invest in  other U.S. Government securities,
such as  those  issued by  the  Government National  Mortgage  Association,  the
Federal  Home Loan Mortgage  Corporation and the  Small Business Administration.
The Fund may  acquire any of  the above  securities on a  forward commitment  or
when-issued  basis.  The Fund  will not  enter  into repurchase  agreements. The
shares of the Fund are not insured or guaranteed by the U.S. Government.
 
CERTAIN SECURITIES, INVESTMENT TECHNIQUES AND ASSOCIATED RISK FACTORS
 
U.S. GOVERNMENT SECURITIES. Each Fund may invest in U.S. Government  securities.
Some  U.S. Government securities, such as  U.S. Treasury bills, notes and bonds,
which differ only in their interest rates, maturities and times of issuance, are
supported by  the  full  faith and  credit  of  the United  States.  Others  are
supported  either  by  (i) the  right  of the  issuer  to borrow  from  the U.S.
Treasury,  such  as  securities  of  the  Federal  Home  Loan  Banks,  (ii)  the
discretionary  authority  of  the  U.S.  Government  to  purchase  the  agency's
obligations, such as securities of the Federal National Mortgage Association, or
(iii) only the  credit of the  issuer, such  as securities of  the Student  Loan
Marketing  Association. No assurance can be  given that the U.S. Government will
provide financial support in the future to U.S. Government agencies, authorities
or instrumentalities that are not supported by the full faith and credit of  the
United States.
 
     Securities  guaranteed as to principal and interest by the U.S. Government,
its agencies, authorities or instrumentalities include (i) securities for  which
the  payment of  principal and  interest is backed  by an  irrevocable letter of
credit issued by  the U.S.  Government or any  of its  agencies, authorities  or
instrumentalities   and   (ii)   participations  in   loans   made   to  foreign
 
                                       12

governments or other entities that are  so guaranteed. The secondary market  for
certain  of these participations  is limited and, therefore,  may be regarded as
illiquid.
 
     U.S. Government securities may include  zero coupon securities that may  be
purchased when yields are attractive and/or to enhance portfolio liquidity. Zero
coupon  U.S.  Government  securities are  debt  obligations that  are  issued or
purchased at a significant discount  from face value. The discount  approximates
the  total amount  of interest  the security will  accrue and  compound over the
period until  maturity or  the particular  interest payment  date at  a rate  of
interest  reflecting the market  rate of the  security at the  time of issuance.
Zero coupon U.S. Government  securities do not require  the periodic payment  of
interest.  These investments benefit the issuer  by mitigating its need for cash
to meet  debt service,  but also  require a  higher rate  of return  to  attract
investors  who  are willing  to  defer receipt  of  cash. These  investments may
experience greater volatility  in market value  than U.S. Government  securities
that  make regular payments  of interest. The  Fund will accrue  income on these
investments  for  tax  and  accounting  purposes,  which  is  distributable   to
shareholders  and which, because no cash is received at the time of accrual, may
require the  liquidation of  other portfolio  securities to  satisfy the  Fund's
distribution  obligations. Zero coupon U.S. Government securities include STRIPS
and CUBES, which are issued by the U.S. Treasury as component parts of  Treasury
Bonds and represent scheduled interest and principal payments on the bonds.
 
     CUSTODIAL  RECEIPTS.  The Money  Market  Fund may  acquire  U.S. Government
securities in the  form of  custodial receipts  or certificates,  such as  CATS,
TIGRs and FICO Strips, underwritten by securities dealers or banks that evidence
ownership  of future  interest payments, principal  payments or  both on certain
notes or  bonds issued  by the  U.S. Government,  its agencies,  authorities  or
instrumentalities. The underwriters of these certificates or receipts purchase a
U.S.  Government security  and deposit the  security in an  irrevocable trust or
custodial  account  with  a  custodian  bank,  which  then  issues  receipts  or
certificates  that evidence ownership of  the periodic unmatured coupon payments
and the  final principal  payment  on the  U.S. Government  security.  Custodial
receipts  evidencing specific coupon or principal payments have the same general
attributes as zero coupon U.S.  Government securities, described above, but  are
not considered by the Trust to be U.S. Government securities. Although typically
under  the terms  of a custodial  receipt the  Fund is authorized  to assert its
rights directly against the issuer of the underlying obligation, the Fund may be
required to assert through the custodian  bank such rights as may exist  against
the  underlying issuer. Thus,  in the event  the underlying issuer  fails to pay
principal and/or interest when due, the Fund may be subject to delays,  expenses
and  risks that are greater than those that would have been involved if the Fund
had purchased a direct obligation of the issuer. In addition, in the event  that
the  trust  or  custodial account  in  which  the underlying  security  has been
deposited is determined to be an  association taxable as a corporation,  instead
of  a non-taxable entity, the yield on  the underlying security would be reduced
in respect of any taxes paid.
 
     SUPRANATIONAL ENTITIES. The Money Market Fund may invest in debt securities
issued by  supranational  organizations  such  as  the  International  Bank  for
Reconstruction  and Development (commonly referred to  as the World Bank), which
was chartered to  finance development projects  in developing member  countries;
the European Community, which is a 12-nation organization engaged in cooperative
economic activities; the European Coal and Steel Community, which is an economic
union  of various  European nations'  steel and  coal industries;  and the Asian
Development Bank, which is an international development bank established to lend
funds,
 
                                       13

- --------------------------------------------------------------------------------
promote investment and  provide technical  assistance to member  nations in  the
Asian and Pacific regions.
 
     FOREIGN  SECURITIES.  The  Money  Market Fund  may  invest  in  U.S. dollar
denominated securities of foreign issuers, including debt securities of  foreign
corporations,  securities  issued  by foreign  governments  and  certificates of
deposit, bankers' acceptances, fixed time deposits and other obligations  issued
by  major  foreign  banks,  foreign  branches  or  subsidiaries  of  U.S.  banks
(Eurodollar obligations), U.S.  branches of foreign  banks (Yankee  obligations)
and foreign branches of foreign banks. Investment in foreign securities and bank
obligations  may present  a greater degree  of risk than  investment in domestic
securities because of less publicly  available financial and other  information,
less  securities  regulation, potential  imposition  of foreign  withholding and
other taxes, war, expropriation or  other adverse governmental actions.  Foreign
banks  and their foreign branches are  not regulated by U.S. banking authorities
and generally are not bound by the accounting, auditing and financial  reporting
standards applicable to U.S. banks. In addition, the Fund may experience greater
difficulty  in obtaining and enforcing a  judgment against a foreign issuer than
against a domestic issuer.
 
   
     COMMERCIAL PAPER. The Money  Market Fund may  invest without limitation  in
fixed or variable rate commercial paper, including variable amount master demand
notes,  issued by U.S. or foreign  corporations. Commercial paper when purchased
by the Fund must be rated  at least P-1 by Moody's, A-1  by S&P or F-1 by  Fitch
or,  if not  rated, must  be determined  by Mitchell  Hutchins acting  under the
supervision of  the Board  of Trustees  to be  of comparable  high quality.  Any
purchase  of commercial paper that  is unrated or rated  only by a single rating
agency must be  approved or ratified  by the Board  of Trustees. Any  commercial
paper  issued by  a foreign corporation  and purchased  by the Fund  must not be
subject to foreign withholding tax at the time of purchase.
    
 
   
     Variable amount master demand notes  are unsecured instruments that  permit
the  indebtedness to vary  and provide for periodic  adjustments in the interest
rate.  Because  variable   amount  master  demand   notes  are  direct   lending
arrangements  between the  Fund and  the issuer,  they are  not normally traded.
Although no active  secondary market may  exist for these  notes, the Fund  will
purchase  only those  notes under  which it  may demand  and receive  payment of
principal and accrued interest daily  or may resell the  note to a third  party.
While  the notes are not typically rated by statistical rating agencies, issuers
of variable amount master demand notes  must satisfy Mitchell Hutchins that  the
same criteria are met as are set forth above for issuers of commercial paper. In
the  event an  issuer of  a variable  rate master  demand note  defaulted on its
payment obligation, the Fund might be unable  to dispose of the note because  of
the absence of a secondary market and could, for this or other reasons, suffer a
loss to the extent of the default.
    
 
   
     OTHER  CORPORATE  DEBT OBLIGATIONS.  The Money  Market  Fund may  invest in
bonds, notes and  debentures issued  by U.S. corporations  that at  the time  of
purchase  meet the  Fund's maturity  requirements and are  rated at  least Aa by
Moody's or AA by S&P or, if not rated, are determined by Mitchell Hutchins to be
of comparable high  quality. Any purchase  of an obligation  that is unrated  or
rated  only by a single rating agency must  be approved or ratified by the Board
of Trustees.
    
 
     REPURCHASE AGREEMENTS.  The Money  Market Fund  may enter  into  repurchase
agreements  with selected broker-dealers, banks or other financial institutions.
A repurchase agreement is an agreement under which the Fund purchases securities
and the seller agrees to repurchase the
 
                                       14
 
<PAGE>
- --------------------------------------------------------------------------------
securities at a particular  time and a specified  price. This price will  exceed
the  original purchase price, the difference being  income to the Fund, and will
be unrelated  to  the interest  rate  on  the purchased  security.  The  Trust's
custodian  will maintain custody of the purchased securities for the duration of
the  agreement.  The  value  of  the  purchased  securities,  including  accrued
interest,  will at all times be equal to not  less than 102% of the value of the
repurchase agreement. In the event of bankruptcy of the seller or failure of the
seller to repurchase  the securities as  agreed, the Fund  could suffer  losses,
including  loss of interest on or principal of the security and costs associated
with delay and enforcement of its rights under the repurchase agreement.
 
     LOAN  PARTICIPATIONS.   The  Money   Market  Fund   may  invest   in   loan
participations.  A  loan  participation is  an  interest  in a  loan  to  a U.S.
corporation that is administered and sold by an intermediary bank. The  borrower
of  the underlying  loan will be  deemed to  be the issuer  of the participation
interest except to the extent the Fund derives its rights from the  intermediary
bank  that  sold  the  loan  participation.  Loan  participations  are  illiquid
securities and, accordingly, the Fund's  investments in them, together with  all
other illiquid securities, will not exceed 10% of the Fund's net assets.
 
   
     FORWARD  COMMITMENTS  AND WHEN-ISSUED  SECURITIES.  Each Fund  may purchase
when-issued securities and enter into  contracts to purchase or sell  securities
for  a  fixed  price  at  a future  date  beyond  customary  settlement  time. A
purchasing Fund is required  to hold and maintain  in a segregated account  with
the Trust's custodian until the settlement date cash, U.S. Government securities
or  other high quality, liquid debt obligations  in an amount sufficient to meet
the purchase price. Alternatively, the Fund may enter into offsetting  contracts
for  the forward sale of other securities  that it owns. Securities purchased or
sold on a when-issued or forward commitment basis involve a risk of loss if  the
value  of the security to be purchased  declines prior to the settlement date or
if the value of the security to be sold increases prior to the settlement  date.
Although  a Fund generally would purchase securities on a when-issued or forward
commitment basis with the intention  of acquiring securities for its  portfolio,
the  Fund may dispose of  a when-issued security or  forward commitment prior to
settlement if Mitchell Hutchins deems it appropriate to do so. The Fund will not
accrue income prior  to the delivery  or issuance of  securities purchased on  a
when-issued or forward commitment basis.
    
 
   
     LENDING OF PORTFOLIO SECURITIES. The Money Market Fund may seek to increase
its  income by lending portfolio  securities. Under present regulatory policies,
these loans  may  be made  to  institutions,  such as  broker-dealers,  and  are
required  to be secured continuously by  collateral in cash, cash equivalents or
U.S. Government securities maintained on a  current basis in an amount at  least
equal  to  the  market value  of  the  securities loaned.  If  Mitchell Hutchins
determines to  make securities  loans, it  is  intended that  the value  of  the
securities  loaned would not exceed 30% of the  value of the total assets of the
Fund. As  with  other  extensions  of  credit,  there  are  risks  of  delay  in
recovering, or even loss of rights in, the collateral should the borrower of the
securities fail financially.
    
 
CERTAIN INVESTMENT POLICIES
 
     INVESTMENT  RESTRICTIONS.  The Trust  on behalf  of  each Fund  has adopted
certain investment restrictions that are  enumerated in detail in the  Statement
of  Additional Information.  Among other restrictions,  each Fund  may not, with
respect to 75% of its total assets taken at market value, invest more than 5% of
its  total  assets   in  the  securities   of  any  one   issuer  (except   U.S.
 
                                       15
 
<PAGE>
- --------------------------------------------------------------------------------
Government  securities and,  with respect to  the Money  Market Fund, repurchase
agreements collateralized by  U.S. Government securities)  or acquire more  than
10%  of any  class of the  outstanding voting  securities of any  one issuer. In
addition, each  Fund  may not  invest  more than  25%  of its  total  assets  in
securities  of  issuers in  any  one industry,  provided  that there  is  no 25%
limitation in respect of, and the  Money Market Fund reserves freedom of  action
to concentrate its investments in, U.S. Government securities, obligations other
than  commercial  paper  issued  or  guaranteed  by  U.S.  banks  and repurchase
agreements and loans of securities collateralized by U.S. Government  securities
or these bank obligations. The Trust, on behalf of a Fund, may borrow money as a
temporary  measure from banks in an  aggregate amount not exceeding one-third of
the value of the Fund's total assets.  A Fund may not purchase securities  while
borrowings exceed 5% of the value of the Fund's assets.
 
     The  investment restrictions listed above, as well as the Funds' investment
objective, are  fundamental policies  and accordingly  may not  be changed  with
respect to any Fund without the approval of a majority of the outstanding shares
of  that Fund, as defined in the Investment Company Act of 1940, as amended (the
'Act'). Unless otherwise specifically  stated, however, the investment  policies
and  practices of each Fund are not fundamental  and may be changed by the Board
of Trustees.
 
     Notwithstanding the restrictions  listed above, to  the extent required  by
the  rules of the SEC, the Money Market Fund will not invest more than 5% of its
assets in the obligations of  any one issuer. A Fund  will not invest more  than
10%  of the value of  its net assets in  securities that are illiquid, including
time deposits and  repurchase agreements maturing  in more than  seven days  and
that  cannot be  liquidated prior  to maturity, as  well as  securities that are
illiquid by virtue of the absence of a readily available market. Securities that
have legal or contractual  restrictions on resale but  have a readily  available
market are not deemed illiquid for this purpose.
 
   
     PORTFOLIO  QUALITY  AND  MATURITY. Each  Fund  maintains  a dollar-weighted
average portfolio maturity of 90 days or less. All securities in which each Fund
invests have remaining maturities of 397 days  or less on the date of  purchase,
are  denominated in U.S. dollars and have  been determined to be of high quality
by nationally recognized statistical rating organizations or determined to be of
comparable quality if not so rated.  A description of these ratings is  provided
in  the Appendix to the Statement  of Additional Information. Mitchell Hutchins,
acting under the supervision of and procedures adopted by the Board of Trustees,
will determine that unrated securities purchased  by a Fund are of high  quality
and  will  determine that  all securities  purchased by  a Fund  present minimal
credit risks and any purchase of unrated securities or securities that are rated
only by a  single rating agency  will be approved  or ratified by  the Board  of
Trustees.  Mitchell  Hutchins  will,  under  the  supervision  of  the  Board of
Trustees, cause a Fund to dispose of any security as soon as practicable if  the
security  is no longer of high quality,  unless the Board of Trustees determines
that this action would not  be in the best interest  of the Fund. High  quality,
short term instruments may result in a lower yield than instruments with a lower
quality or a longer term.

                       PURCHASE AND REDEMPTION OF SHARES
    
 
NET ASSET VALUE
 
   
The  net asset  value of each  Fund is  determined daily at  12:00 noon, Eastern
time, Monday through Friday, except  that net asset value  is not computed on  a
day  in which no  orders to purchase,  sell, exchange or  redeem any Fund shares
have been received, any day on which there is not sufficient trading in a Fund's
portfolio securities  that  the  Fund's  net asset  value  per  share  might  be
materially  affected by changes in the value  of such portfolio securities or on
days on which the New York Stock Exchange is not open for trading. The New  York
Stock  Exchange  currently  is  scheduled  to  be  closed  on  New  Year's  Day,
Presidents' Day,  Good  Friday,  Memorial  Day,  Independence  Day,  Labor  Day,
Thanksgiving  and  Christmas, and  on  the preceding  Friday  when one  of those
holidays falls on  a Saturday  or on  the subsequent  Monday when  one of  those
holidays falls on a Sunday. Net asset value per share of each Fund is calculated
by  adding the value of all securities and other assets of the Fund, subtracting
the liabilities  of  the  Fund and  dividing  the  remainder by  the  number  of
outstanding  shares of the Fund. Each  Fund's portfolio securities are valued at
their amortized  cost which  does not  take into  account unrealized  securities
gains  or losses.  This method involves  initially valuing an  instrument at its
cost and thereafter assuming a constant amortization to maturity of any  premium
paid  or discount received. Each Fund attempts  to maintain a constant net asset
value of $1.00 per share but there can  be no assurance that it will be able  to
do so on a continuing basis.
    
 
PURCHASE PROCEDURES
 
   
PaineWebber,  1285 Avenue  of the  Americas, New  York, New  York 10019,  is the
distributor of  the Trust's  shares.  Shares must  be purchased  and  maintained
through  a  brokerage  account  with  Kidder, Peabody,  for  which  there  is no
maintenance fee.  Shares of  the  Funds also  may  be purchased  and  maintained
through  the Kidder, Peabody  Premium Account asset  management system. Purchase
orders must be transmitted by  telephone (800-543-3373 or 800-KIDDER3),  through
the Trust's computer investment implementation system or through the ACH system.
Payment  for purchase orders  also may be  made by check  or draft, as described
below. Investors interested in establishing a Kidder, Peabody brokerage account,
participating in the  Kidder, Peabody Premium  Account asset management  system,
utilizing  the Trust's computer investment  implementation system or through the
ACH system or obtaining compatible computer hardware or software should  contact
any  Kidder,  Peabody Investment  Executive or  call  the Trust  at 800-543-3373
(800-KIDDER3) for further information. Shareholder inquiries regarding the Trust
may be made in the same manner.
    
 
     Each Fund  proposes to  offer  investors the  choice  of investing  in  two
separate  classes of  shares representing pro  rata interests  in its investment
portfolio  --   Institutional   shares  and   Financial   Intermediary   shares.
Institutional  shares in each  Fund are available  for purchase by institutional
investors, although the  Trust and Kidder,  Peabody reserve the  right to  waive
this  requirement. Financial Intermediary shares in  each Fund are available for
purchase by banks and  other financial intermediaries for  the benefit of  their
customers  and bear all fees payable by the Fund to financial intermediaries for
certain services they provide to the beneficial owners of these shares.
 
                                       17
 
<PAGE>
- --------------------------------------------------------------------------------
 
     Shares are sold  at the  net asset value  per share  next determined  after
receipt  of a  purchase order  by Kidder,  Peabody. Orders  received before 1:00
p.m., New York time, for which payment has been received by Kidder, Peabody will
be executed at that time and the shareholder will receive the dividend  declared
on that day. Orders received after 1:00 p.m., New York time, and orders received
earlier  in the same day  for which payment has not  been received by 1:00 p.m.,
New York time, will be executed at 4:00 p.m., New York time, if payment has been
received by Kidder, Peabody  by that time and  the shareholder will receive  the
dividend  declared  on the  following day.  Orders received  at other  times and
orders for which payment has not been received by 4:00 p.m., New York time, will
not be accepted and  notice thereof will  be given to  the investor placing  the
order.
 
     In  order  to  maximize earnings,  each  Fund  attempts to  be  invested as
completely as practicable and is normally required to make settlement in Federal
funds for  securities purchased.  Accordingly, payment  for Fund  shares is  not
effective  until received in or converted to Federal funds immediately available
to the Trust. The minimum initial investment in any Fund or combination of Funds
is $250,000, which may be waived at the discretion of Kidder, Peabody;  however,
financial  intermediaries purchasing shares for  the accounts of their customers
may set a  higher minimum for  their customers. There  is no minimum  subsequent
investment.  The Trust and Kidder, Peabody each reserves the right to reject any
purchase order for any reason.
 
REDEMPTION PROCEDURES
 
Redemption orders must be transmitted  to Kidder, Peabody by telephone,  through
the  Trust's computer investment implementation system or through the ACH system
in the manner described under 'Purchase Procedures.' Shares are redeemed at  the
net asset value per share next determined after Kidder, Peabody's receipt of the
redemption  order. Payment for  redeemed shares for which  a redemption order is
received by Kidder, Peabody before 1:00 p.m., New York time, is normally made in
Federal funds  wired to  the redeeming  shareholder on  the same  business  day.
Shares  redeemed in this manner are not entitled to the dividend declared on the
day of redemption. Payment for redemption orders that are received between  1:00
p.m.,  New York time, and 4:00 p.m., New York time, normally is wired in Federal
funds on the next business day following the redemption. Shares redeemed in this
manner are entitled to the dividend  declared on the day of redemption.  Kidder,
Peabody  effects all wire transfers free of charge. In times of drastic economic
or market  changes,  the  telephone  redemption  feature  may  be  difficult  to
implement.
 
EXCHANGES
 
   
Shares  of each Fund may be exchanged for  shares of the same class of any other
Fund  at  net  asset  value  next  determined  by  telephone  (800-543-3373   or
800-KIDDER3)  or through the Trust's  computer investment implementation system.
In times of drastic economic or market changes, the telephone exchange privilege
may be  difficult  to implement.  The  exchange  privilege may  be  modified  or
terminated  in accordance with the  rules of the SEC.  The exchange privilege is
available to shareholders resident in any  state in which the Fund shares  being
acquired legally may be sold.

PURCHASES AND REDEMPTIONS THROUGH THE AUTOMATIC CLEARING HOUSE SYSTEM
 
Shares  of a Fund  may be purchased  and redeemed through  a program designed by
Kidder, Peabody to help businesses manage their cash flow and earn money  market
rates  of return through investment  in the Fund. This  program utilizes the ACH
system to transfer monies electronically between the corporate investor's  local
bank  and the Trust. The purchase of shares of the Fund through this program may
be arranged  by completing  a  Kidder, Peabody  ACH  application, which  can  be
obtained  by  calling 800-543-3373  (800-KIDDER3)  and returning  it  to Kidder,
Peabody. After the application is received, an announcement card will be sent to
the corporation supplying it with an  account number and advising it that  after
15  days from the printed  date on the card the  corporation may begin using the
ACH system for purchasing or redeeming Fund shares.
 
     After the waiting period, an  authorized representative of the  corporation
may  call the Trust  (800-543-3373 or 800-KIDDER3),  identify the corporation by
name and account number  and advise the operator  how much cash the  corporation
wishes to invest in the Fund from its local corporate checking account or redeem
from  the Fund and transfer to its checking account. Funds will automatically be
transferred to or from the  Fund via the ACH system  on the second business  day
(or   any  other  business  day  thereafter  selected  by  the  investor)  after
instructions are received by the Trust.
 
PURCHASES BY CHECK OR FEDERAL RESERVE DRAFT
 
Purchase orders for which remittance is to  be made by check or Federal  Reserve
Draft  must be submitted directly by  mail to Liquid Institutional Reserves, Two
Broadway, Seventh Floor,  New York,  New York 10004-2256,  Attn: Services  Asset
Management  Department, together  with payment  for the  purchase price  of such
shares and, in the case of a new account, a completed account application. These
orders will become effective on the day the remittance is converted into Federal
funds and shares will be purchased at the net asset value next determined  after
such  conversion. Checks  and Federal Reserve  Drafts should be  made payable to
Liquid Institutional  Reserves --  [name of  Fund]. Money  transmitted by  check
normally will be converted into Federal funds within two business days following
receipt.  Certified checks are not necessary, but checks are accepted subject to
collection at full face value in U.S. funds and must be drawn on a U.S. bank. In
the event that the  purchase price for  shares is paid by  Federal funds in  the
form  of a Federal Reserve Draft, Federal funds will be available to the Fund on
the next business day  and the investor's  order will be  effected on that  day.
During  the  period of  time  prior to  the  conversion into  Federal  funds, an
investor's money  will not  be  invested and,  therefore,  will not  be  earning
dividends.
 
   
    
 
OTHER MATTERS
 
   
The Trust does not issue certificates representing shares, but PFPC Inc., as the
Trust's  transfer agent, maintains a complete  record of transactions and shares
held in each shareholder's account.
    
 
     The Trust  may suspend  the right  of redemption  or postpone  the date  of
payment  upon redemption (as  well as suspend  or postpone the  recording of the
transfer of its shares) for such periods  as permitted under the Act. The  Trust
also may redeem shares involuntarily under
 
                                       19
 
<PAGE>
- --------------------------------------------------------------------------------
certain   special  circumstances  described  in   the  Statement  of  Additional
Information under 'Purchase and Redemption of Shares.'
 
     Fund shares are  sold and  redeemed without  charge by  the Fund,  although
financial  intermediaries  purchasing  or  holding  shares  for  their  customer
accounts may charge customers for cash management and other services provided in
connection with  their accounts  including,  for instance,  account  maintenance
fees,  compensating balance requirements or  fees based on account transactions,
assets or  income.  Further,  the  dividends payable  to  beneficial  owners  of
Financial  Intermediary shares will be reduced in respect of fees paid by a Fund
to financial intermediaries through which  those shares are purchased and  held.
See  'Management of  the Trust --  Financial Intermediaries.'  A customer should
consider the terms of  his or her account  with a financial intermediary  before
purchasing  shares. A financial  intermediary purchasing or  redeeming shares on
behalf of  its  customers is  responsible  for transmitting  orders  to  Kidder,
Peabody in accordance with its customer agreements.
 
     Investors  desiring to engage in purchase, sale or exchange transactions by
telephone as described  above should  contact their  Kidder, Peabody  Investment
Executives to complete the required documentation. Neither the Trust nor Kidder,
Peabody will be liable for following instructions communicated by telephone that
it  reasonably  believes to  be genuine.  The  Trust employs  certain procedures
designed to confirm  that instructions  communicated by  telephone are  genuine.
Upon  receiving transfer  instructions by telephone,  it is the  practice of the
Trust to compare the transfer instructions received by telephone to the  written
instructions  of the shareholder  on the shareholder's  account opening form. In
the event that the transfer instructions received by the Trust by telephone vary
from the instructions on the shareholder's account opening form, the Trust  will
require  written  instructions  that  are  accompanied  by  a  signature  of the
registered shareholder  that  matches the  signature  on file  with  the  Trust.
Failure  to employ  these procedures may  cause the  Funds to be  liable for any
losses due to unauthorized or fraudulent instructions.
 
                            MANAGEMENT OF THE TRUST
 
TRUSTEES AND OFFICERS
 
The business and affairs  of the Trust  are managed under  the direction of  its
Board  of Trustees. The day-to-day operations of the Trust are conducted through
or under the direction of its officers. The Statement of Additional  Information
contains  general background information  regarding each Trustee  and officer of
the Trust.
 
   
INVESTMENT ADVISER AND ADMINISTRATOR
    
 
   
At a  special  meeting  of shareholders  that  took  place on  April  13,  1995,
shareholders  approved a  new investment  advisory and  administration agreement
with PaineWebber and  a new sub-advisory  and sub-administration agreement  with
Mitchell  Hutchins. PaineWebber and Mitchell Hutchins are located at 1285 Avenue
of the Americas, New York, New York  10019. Mitchell Hutchins is a wholly  owned
subsidiary  of PaineWebber, which in turn is  wholly owned by Paine Webber Group
Inc., a publicly owned financial services holding company. As of July 31,  1995,
PaineWebber  or Mitchell Hutchins served as investment adviser or sub-adviser to

investment companies with an aggregate of [77] separate portfolios and aggregate
assets of approximately [$26] billion.
    
 
   
     The Funds  pay the  same  fee for  investment advisory  and  administration
services  to PaineWebber as previously paid  to Kidder Peabody Asset Management,
Inc. ('KPAM'),  the Fund's  predecessor  investment adviser  and  administrator.
PaineWebber  (not the  Funds) pay Mitchell  Hutchins a fee  for sub-advisory and
sub-administration services at  the annual rate  of 20% of  the fee received  by
PaineWebber from the Funds. PaineWebber and Mitchell Hutchins continue to manage
the  Funds in  accordance with  the Funds'  investment objectives,  policies and
restrictions.
    
 
   
     As compensation for  PaineWebber's services,  each Fund has  agreed to  pay
PaineWebber a fee, accrued daily and paid monthly, at the annual rate of .25% of
each  Fund's average  daily net assets.  PaineWebber has  undertaken to maintain
each Fund's total annual  operating expenses at a  level not exceeding .35%  and
 .60%  of the Fund's  average daily net assets  annually for Institutional shares
and Financial Intermediary shares, respectively. After PaineWebber's waiver of a
portion of the fees due it from the Treasury Securities Fund, the Fund paid fees
for the fiscal year ended April 30, 1995 of    % of its average daily net assets
with respect  to Financial  Intermediary  shares. With  respect to  each  Fund's
Institutional  shares, for the fiscal year  ended April 30, 1995, the Government
Securities Fund's,  Money Market  Fund's and  Treasury Securities  Fund's  total
expenses  represented    %,     % and     %, respectively,  of their average net
assets. With respect to  the Financial Intermediary shares  of the Money  Market
Fund  and the Government Securities Fund, for  the fiscal period ended April 30,
1995, total expenses represented    %  and    %, respectively, of their  average
daily net assets.
    
 
   
     Although  investment decisions  for each  Fund are  made independently from
those of the  other accounts managed  by Mitchell Hutchins,  investments of  the
type  each Fund may make may  also be made by those  other accounts. When a Fund
and one or  more other  accounts managed by  Mitchell Hutchins  are prepared  to
invest  in, or desire to dispose of, the same security, available investments or
opportunities for sales are allocated in a manner believed by Mitchell  Hutchins
to  be equitable to each. In some cases, this procedure may adversely affect the
price paid or  received by  the Fund  or the size  of the  position obtained  or
disposed of by the Fund.
    
 
CUSTODIAN AND TRANSFER, DIVIDEND AND RECORDKEEPING AGENT
 
   
State  Street  Bank  and  Trust  Company,  One  Heritage  Drive,  North  Quincy,
Massachusetts 02171, serves as the Trust's custodian. PFPC Inc., a subsidiary of
PNC Bank, National Association, whose principal address is 400 Bellevue Parkway,
Wilmington,  Delaware  19809,  serves  as  the  Trust's  transfer  dividend  and
recordkeeping agent.
    
 
FINANCIAL INTERMEDIARIES
 
Financial  intermediaries, such as banks and  savings and loan associations, may
purchase Financial  Intermediary shares  for the  accounts of  their  customers.
Financial  Intermediary shares  are identical  in all  respects to Institutional
shares except that  beneficial owners of  Financial Intermediary shares  receive
certain  services directly from financial  intermediaries, bear the service fees
described below and enjoy certain exclusive voting rights on matters relating to
these
 
                                       21

- --------------------------------------------------------------------------------
   
services and  fees. The  Trust will  enter into  a service  agreement with  each
financial intermediary that purchases Financial Intermediary shares requiring it
to  provide support services to  its customers who are  the beneficial owners of
Financial Intermediary shares in consideration  of the Trust's payment of  .25%,
on  an annualized basis, of  the average daily net  asset value of the Financial
Intermediary shares held by  the financial intermediary for  the benefit of  its
customers.  These  services,  which  are  described  in  greater  detail  in the
Statement of Additional Information under 'Management of the Trust --  Financial
Intermediaries,'  include:  aggregating and  processing purchase  and redemption
requests from  customers and  placing net  purchase and  redemption orders  with
PaineWebber; providing customers with a service that invests the assets of their
accounts  in  Financial  Intermediary shares;  processing  dividend  payments on
behalf of  customers; providing  information periodically  to customers  showing
their  positions  in Financial  Intermediary shares;  arranging for  bank wires;
responding to  customer inquiries  relating  to the  services performed  by  the
financial  intermediary;  providing  sub-accounting  with  respect  to Financial
Intermediary shares beneficially owned by customers or the information necessary
for  sub-accounting;  forwarding  shareholder  communications  from  a  Fund  to
customers,  if required by law; and such other similar services as the Trust may
reasonably request from time to time to the extent the financial intermediary is
permitted to do  so under  federal and  state statutes,  rules and  regulations.
Under the terms of the service agreements, financial intermediaries are required
to  provide to their customers  a schedule of any  additional fees that they may
charge customers in connection with their investments in Financial  Intermediary
shares.  Financial  Intermediary  shares  are  available  for  purchase  only by
financial intermediaries  that have  entered into  service agreements  with  the
Trust  in connection  with their investment.  Financial intermediaries providing
services to beneficial owners of Financial Intermediary shares in certain states
may be required to be registered as dealers under the laws of those states.
    
 
     Should future legislative,  judicial or administrative  action prohibit  or
restrict  the  activities  of  banks  serving  as  financial  intermediaries  in
connection with the provision of support services to their customers, the  Trust
might  be  required  to alter  or  discontinue its  arrangements  with financial
intermediaries and change  its method  of operations with  respect to  Financial
Intermediary  shares. It  is not  anticipated, however,  that any  change in the
Trust's method of  operations would  affect its net  asset values  per share  or
result in a financial loss to any shareholder.
 
                       DIVIDENDS, DISTRIBUTIONS AND TAXES
 
DIVIDENDS AND DISTRIBUTIONS
 
   
Substantially  all of each Fund's net  investment income (i.e., its income other
than its net realized long term and short term capital gains) are declared daily
as a dividend and  paid to shareholders  shortly before the  end of each  month.
Each Fund declares and distributes at least  annually,  after  the close  of its
fiscal year, substantially all  of its net  realized  short term  and long  term
capital gains, if any. Dividends  and capital gains  distributions  are  made in
additional  shares  of  the  same  class  and  Fund  or,  at  the  election   of
shareholders,  in cash, as  the  case may be, prior to the  last business day of
each month. The  election to  reinvest  dividends and  distributions or  receive
them in cash may be changed at  any  time  upon written  notice to  PaineWebber.
Although  realized gains  and losses  on the assets of each Fund  are  reflected
in the net asset value of each Fund, they are not expected  to be  of an  amount
that would affect a Fund's  net asset value of $1.00 per share.
    
 
                                       22
 
<PAGE>
- --------------------------------------------------------------------------------
 
TAXES
 
   
Each  Fund is treated as a separate  entity for federal income tax purposes, has
qualified for the fiscal year ended April 30, 1995 to be treated as a  regulated
investment  company under  the Internal  Revenue Code  of 1986,  as amended (the
'Code'), and has elected or intends to elect this treatment for each year. If  a
Fund (i) qualifies as a regulated investment company and (ii) distributes to its
shareholders  at least  90% of  its net  investment income  (including, for this
purpose, its net realized short term capital  gains), then the Fund will not  be
liable for federal income taxes to the extent that its net investment income and
its  net realized long term and short  term capital gains are distributed to its
shareholders. The  Trust  anticipates that  each  Fund will  distribute  to  its
shareholders  at least  90% of  its net  investment income  (including, for this
purpose, its net realized short term capital gains) in each of its fiscal years.
Further, the Code imposes a 4% non-deductible excise tax on a Fund to the extent
that a  Fund does  not  distribute by  the end  of  each calendar  year  certain
undistributed  amounts of net  investment income and net  realized long term and
short term capital gains. Each Fund  anticipates that it will pay any  dividends
and  make any distributions that are necessary in order to avoid the application
of this excise tax.
    
 
     Dividends of net investment income and distributions of net realized  short
term  capital  gains, as  a general  rule,  will be  taxable to  shareholders as
ordinary income whether received in cash or reinvested in additional shares. The
Trust does not expect the Funds to realize any long term capital gains and  thus
does  not contemplate that the Funds  will pay dividends taxable to shareholders
as long term  capital gains.  The Funds'  dividends and  distributions will  not
qualify  for the dividends-received deduction  for corporations. Some states, if
certain  asset   and   diversification  requirements   are   satisfied,   permit
shareholders to treat their portions of a Fund's dividends that are attributable
to  interest on U.S. Treasury securities  and certain U.S. Government securities
as  income  that  is  exempt  from  state  and  local  income  taxes.  Dividends
attributable to repurchase agreement earnings are, as a general rule, subject to
state and local taxation.
 
     It is anticipated that the Money Market Fund's portfolio will be managed so
as  to avoid application  of foreign withholding  taxes. To the  extent the Fund
invests in foreign securities, it may be subject to foreign withholding taxes on
income earned on  these securities  and may  be unable  to pass  through to  its
shareholders foreign tax credits and deductions with respect to these taxes.
 
     Statements  as  to  the  tax status  of  each  shareholder's  dividends and
distributions are mailed  annually. These statements,  among other things,  tell
shareholders  of the portions  of their dividends that  are attributable to U.S.
Treasury securities  and  specific types  of  U.S. Government  securities.  Each
shareholder  also receives,  if appropriate,  various written  notices after the
close of the Fund's prior  tax year as to the  federal income tax status of  the
shareholder's  dividends  and distributions  that  were received  from  the Fund
during the Fund's prior taxable year. Shareholders should consult their own  tax
advisors to assess the consequences of investing in a Fund under state and local
laws  generally and to determine whether dividends paid by a Fund that represent
interest derived from  U.S. Treasury  and other U.S.  Government securities  are
exempt from any applicable state or local taxes.

                             DESCRIPTION OF SHARES
 
The  Trust was formed as a business trust  under the laws of the Commonwealth of
Massachusetts on  February 14,  1991. The  Declaration of  Trust authorizes  the
Board  of Trustees to create separate series of an unlimited number of shares of
beneficial interest, par value $.001 per share. The Declaration of Trust further
authorizes the Trustees to classify or reclassify any series of shares into  one
or  more classes.  The Trustees  have authorized  the issuance  of Institutional
shares and Financial Intermediary shares of each of the three Funds.
 
     When issued, shares are  fully paid and  non-assessable. Shares are  freely
transferable  and have no  pre-emptive, subscription or  conversion rights. Each
Institutional share and  Financial Intermediary  share of a  Fund represents  an
equal, proportionate interest in the assets belonging to that Fund. Thus, in the
event  of liquidation, shareholders  are entitled to  share pro rata  in the net
assets of the applicable Fund available for distribution to shareholders. Except
as described  in this  Prospectus,  the two  classes  of shares  are  identical.
Certain aspects of the shares may be altered, upon notice to shareholders, if it
is deemed necessary in order to satisfy certain tax regulatory requirements.
 
     Holders  of  each Fund's  Institutional  shares and  Financial Intermediary
shares will vote in the aggregate and  not by class on all matters except  where
otherwise  required by  law and except  that only  Financial Intermediary shares
will be  entitled  to  vote on  matters  submitted  to a  vote  of  shareholders
pertaining  to the Trust's arrangements  with financial intermediaries. Further,
shareholders of the Trust will vote in  the aggregate and not by Fund except  as
otherwise  required by  law or  when the Board  of Trustees  determines that the
matter to be  voted upon affects  only the  interests of the  shareholders of  a
particular  Fund. Shareholders of  the Trust are  entitled to one  vote for each
full share held and fractional votes for fractional shares held, irrespective of
class or Fund. Voting rights are not cumulative and, accordingly, the holders of
more than  50% of  the  aggregate shares  of  the Trust  may  elect all  of  the
Trustees.  The  Trust  does  not intend  to  hold  annual  shareholder meetings,
although special  meetings  may be  called  for  purposes such  as  electing  or
removing  Trustees  or such  other purposes  as  are described  above. Financial
intermediaries holding shares for their own accounts have undertaken to vote the
shares in the same proportions as the vote of shares held for their customers.

Liquid  Institutional Reserves (the  'Trust') is a  no-load, open-end investment
company offering shares in three separate, diversified, money market funds  (the
'Funds').  Each Fund seeks high current income to the extent consistent with the
preservation of capital and the maintenance of liquidity through investments  in
high quality, short term, U.S. dollar denominated money market instruments.

                       INVESTMENT OBJECTIVE AND POLICIES
 
The following discussion elaborates on the description of each Fund's investment
policies and practices contained in the Prospectus.
 
CUSTODIAL RECEIPTS
 
The  Money Market Fund may acquire custodial receipts that evidence ownership of
future interest payments, principal payments or both on certain U.S.  Government
notes or bonds. These notes and bonds are held in custody by a bank on behalf of
the  owners.  These custodial  receipts are  known  by various  names, including
'Treasury  Receipts,'  'Treasury  Investors  Growth  Receipts'  ('TIGRs'),   and
'Certificates  of Accrual  on Treasury Securities'  ('CATS'). Although custodial
receipts are not considered  U.S. Government securities by  the Trust, they  are
indirectly  issued  or  guaranteed as  to  principal  and interest  by  the U.S.
Government, its agencies, authorities or instrumentalities.
 
CORPORATE AND BANK OBLIGATIONS
 
Commercial paper represents  short term,  unsecured promissory  notes issued  in
bearer  form  by  banks  or bank  holding  companies,  corporations  and finance
companies. The commercial paper purchased by  the Money Market Fund consists  of
direct U.S. dollar denominated obligations of domestic or foreign issuers.
 
     Bank  obligations  in  which  the  Money  Market  Fund  may  invest include
certificates  of  deposit,  bankers'   acceptances  and  fixed  time   deposits.
Certificates  of  deposit  are  negotiable  certificates  issued  against  funds
deposited in a  commercial bank  for a  definite period  of time  and earning  a
specified  return.  Bankers'  acceptances  are  negotiable  drafts  or  bills of
exchange, normally  drawn  by  an  importer or  exporter  to  pay  for  specific
merchandise,  that are 'accepted' by  a bank, meaning, in  effect, that the bank
unconditionally agrees to  pay the  face value  of the  instrument on  maturity.
Fixed  time deposits are bank obligations payable  at a stated maturity date and
bearing interest at a fixed rate. Fixed time deposits may be withdrawn on demand
by the  investor but  may be  subject to  early withdrawal  penalties that  vary
depending  upon market conditions and the  remaining maturity of the obligation.
There are no  contractual restrictions  on the  right to  transfer a  beneficial
interest  in a fixed time deposit to a  third party, although there is no market
for these deposits.
 
REPURCHASE AGREEMENTS
 
The Money  Market  Fund  may  enter into  repurchase  agreements  with  selected
broker-dealers, banks or other financial institutions. A repurchase agreement is
an  arrangement  under which  the purchaser  (i.e., the  Fund) purchases  a U.S.
Government or other high quality  short term debt obligation (the  'Obligation')
and  the seller agrees, at  the time of sale, to  repurchase the Obligation at a
specified time and price.  Custody of the Obligation  will be maintained by  the
Trust's  custodian. The repurchase price may  be higher than the purchase price,
the difference being income to the  Fund, or the purchase and repurchase  prices
may  be the same, with interest  at a stated rate due  to the Fund together with
the repurchase price on repurchase.  In either case, the  income to the Fund  is
unrelated  to  the interest  rate on  the Obligation  subject to  the repurchase
agreement.
 
     For purposes of the Investment Company Act of 1940, as amended (the 'Act'),
a repurchase agreement is deemed to be a loan from the Fund to the seller of the
Obligation. It  is not  clear  whether a  court  would consider  the  Obligation
purchased by the Fund subject to a repurchase
 
                                       2
 
<PAGE>
- --------------------------------------------------------------------------------
   
agreement  as being owned by the  Fund or as being collateral  for a loan by the
Fund to the  seller. In the  event of commencement  of bankruptcy or  insolvency
proceedings  with respect to  the seller of the  Obligation before repurchase of
the Obligation under a  repurchase agreement, the Fund  may encounter delay  and
incur  costs before being able to sell  the Obligation. This delay may involve a
loss of  interest or  a decline  in  the price  of the  Obligation. If  a  court
characterizes  the  transaction as  a  loan and  the  Fund has  not  perfected a
security interest in  the Obligation,  the Fund may  be required  to return  the
Obligation to the seller's estate and be treated as an unsecured creditor of the
seller.  As an unsecured creditor,  the Fund would be at  risk of losing some or
all of  the principal  and interest  involved in  the transaction.  As with  any
unsecured  debt  instrument  purchased  for  the  Fund,  the  Trust's investment
sub-adviser, Mitchell  Hutchins  Asset Management  Inc.  ('Mitchell  Hutchins'),
seeks  to minimize the risk of loss  from repurchase agreements by analyzing the
creditworthiness of the obligor, in this case, the seller of the Obligation. The
Board of Trustees has reviewed and approved certain sellers that it believes  to
be  creditworthy and has authorized the Fund to enter into repurchase agreements
exclusively with these sellers.
    
 
     Apart from the risk of bankruptcy or insolvency proceedings, there is  also
the  risk that the seller  may fail to repurchase  the security. However, if the
market value of the Obligation subject to the repurchase agreement becomes  less
than  the repurchase price  (including accrued interest),  the Trust will direct
the seller of the Obligation to deliver additional securities so that the market
value of all securities  subject to the repurchase  agreement equals or  exceeds
the repurchase price.
 
     Certain  repurchase  agreements that  provide for  settlement in  more than
seven days can be liquidated  before the nominal fixed  term on notice of  seven
days   or  less.  These  repurchase  agreements   will  be  regarded  as  liquid
instruments.
 
FOREIGN SECURITIES
 
The Money Market Fund  may invest in foreign  securities and in certificates  of
deposit,  bankers' acceptances,  and fixed  time deposits  and other obligations
issued by  major foreign  banks,  foreign branches  of  U.S. banks  and  foreign
branches  of  foreign banks.  Under current  Securities and  Exchange Commission
('SEC') rules relating  to the  use of the  amortized cost  method of  portfolio
securities  valuation, the  Money Market Fund  is restricted  to purchasing U.S.
dollar denominated securities  but is  not otherwise  precluded from  purchasing
securities  of  foreign  issuers.  Investments in  foreign  securities  and bank
obligations may involve  considerations different from  investments in  domestic
securities, which are described in the Prospectus.
 
ASSET-BACKED AND RECEIVABLE-BACKED SECURITIES
 
The  Money  Market  Fund  may  invest  in  asset-backed   and  receivable-backed
securities. Several types of asset-backed and receivable-backed securities  have
been  offered to investors, including  'Certificates for Automobile Receivables'
('CARs'sm'') and  interests  in  pools  of  credit  card  receivables.  CARs'sm'
represent undivided fractional interests in a trust, the assets of which consist
of a pool of  motor vehicle retail  installment  sales  contracts  and  security
interests in the vehicles  securing the  contracts.  Payments of  principal  and
interest  on CARs'sm' are passed through monthly to  certificate holders and are
guaranteed up to certain amounts and for a certain  time period  by a letter  of
credit  issued by a  financial  institution  unaffiliated  with  the trustee  or
originator  of  the trust. An investor's return  on CARs'sm' may  be affected by
early prepayment of principal on the underlying vehicle sales contracts.  If the
letter of credit  is exhausted, the trust may be prevented
 
                                       3
 
<PAGE>
- --------------------------------------------------------------------------------
from  realizing the  full amount due  on a  sales contract because  of state law
requirements and restrictions relating to foreclosure sales of vehicles and  the
availability   of  deficiency   judgments  following  such   sales,  because  of
depreciation, damage or loss of a vehicle, because of the application of federal
and state  bankruptcy  and  insolvency  laws or  other  factors.  As  a  result,
certificate  holders may experience delays in payment if the letter of credit is
exhausted. Consistent with  the Fund's  investment objective  and policies  and,
subject  to the review and  approval of the Trust's  Board of Trustees, the Fund
also may invest in other types of asset-backed and receivable-backed securities.
 
FORWARD COMMITMENTS AND WHEN-ISSUED SECURITIES
 
Each Fund may  purchase securities on  a when-issued basis  or purchase or  sell
securities   on  a  forward  commitment  basis.  These  transactions  involve  a
commitment by the  Fund to purchase  or sell  securities at a  future date.  The
price of the underlying securities, usually expressed in terms of yield, and the
date  when the securities will  be delivered and paid  for (i.e., the settlement
date) are fixed at the time the transaction is negotiated. When-issued purchases
and forward commitment transactions are negotiated directly with the other party
and these commitments are not traded on securities exchanges.
 
     A Fund  generally  will  purchase  securities on  a  when-issued  basis  or
purchase  or  sell on  a forward  commitment  basis only  with the  intention of
completing the transaction and actually purchasing or selling the securities. If
deemed advisable  as a  matter of  investment strategy,  however, the  Fund  may
dispose  of or negotiate a commitment after  entering into it. The Fund also may
sell securities  it  has  committed  to purchase  before  those  securities  are
delivered  to the Fund  on the settlement  date. The Fund  may realize a capital
gain or loss in connection with these transactions. For purposes of  determining
the  Fund's average  dollar weighted  maturity, the  maturity of  when-issued or
forward commitment securities will be calculated from the commitment date.
 
     When a Fund  purchases securities  on a when-issued  or forward  commitment
basis,  the Trust's custodian  will maintain in  a segregated account securities
having a value, determined  daily, at least  equal to the  amount of the  Fund's
purchase  commitments. In  the case  of a  forward commitment  to sell portfolio
securities, the custodian  will hold  the portfolio securities  in a  segregated
account  while the commitment  is outstanding. These  procedures are designed to
ensure that the Fund will maintain sufficient  assets at all times to cover  its
obligations under when-issued purchases and forward commitments.
 
LENDING OF PORTFOLIO SECURITIES
 
The  Money Market  Fund may  seek to  increase its  income by  lending portfolio
securities. Under  present  regulatory policies,  these  loans may  be  made  to
institutions,  such  as  broker-dealers, and  would  be required  to  be secured
continuously by  collateral  in cash,  cash  equivalents or  high  quality  U.S.
Government  securities maintained on a current basis at an amount at least equal
to the market value of the securities  loaned. The Fund would have the right  to
call a loan and obtain the securities loaned at any time on five days' notice.
 
     For  the  duration  of a  loan,  the  Fund would  continue  to  receive the
equivalent of the  interest or dividends  paid by the  issuer on the  securities

investment  of the  collateral. The Fund  would not  have the right  to vote any
securities having voting rights during the  existence of the loan, but the  Fund
could  call the  loan in  anticipation of  an important  vote to  be taken among
holders of the securities or of the giving or withholding of their consent on  a
material matter affecting the investment.
 
   
     As with other extensions of credit, there are risks of delay in recovering,
or  even loss of rights in, the collateral should the borrower of the securities
fail financially. The  loans, however,  would be made  only to  firms deemed  by
Mitchell  Hutchins to be of good standing, and when, in the judgment of Mitchell
Hutchins, the income that can be earned currently from securities loans of  this
type  justifies the  attendant risks.  If Mitchell  Hutchins determines  to make
securities loans, it is intended that  the value of the securities loaned  would
not exceed 30% of the value of the total assets of the Fund.
    
 
PARTICIPATION INTERESTS
 
The  Money  Market  Fund  may purchase  participation  interests  in  loans with
remaining maturities of 397 days or less. These loans must be made to issuers in
whose obligations the Fund may invest.  Any participation purchased by the  Fund
must  be issued by a bank in the United States with assets exceeding $1 billion.
Because the issuing bank does not guarantee the participations in any way,  they
are  subject  to  the  credit risks  generally  associated  with  the underlying
corporate borrower. In addition, because it may be necessary under the terms  of
the  loan participation  for the  Fund to assert  through the  issuing bank such
rights as may exist against the underlying corporate borrower, in the event  the
underlying  corporate borrower fails to pay principal and interest when due, the
Fund may be subject to  delays, expenses and risks  that are greater than  those
that  would have been  involved if the  Fund had purchased  a direct obligation,
such as commercial paper, of the borrower. Moreover, under the terms of the loan
participation, the  Fund may  be regarded  as a  creditor of  the issuing  bank,
rather  than of the underlying corporate borrower,  so that the Fund may also be
subject to the risk that the issuing bank may become insolvent. Further, in  the
event  of  the bankruptcy  or  insolvency of  the  corporate borrower,  the loan
participation may be  subject to certain  defenses that can  be asserted by  the
borrower  as a  result of  improper conduct by  the issuing  bank. The secondary
market, if any, for these loan  participations is limited and any  participation
interest may be regarded as illiquid.
 
   
     In  the event that Mitchell Hutchins does not believe that price quotations
currently obtainable  from  banks,  dealers, or  pricing  services  consistently
represent  the market values of participation interests, Mitchell Hutchins will,
following  guidelines  established   by  the  Board   of  Trustees,  value   the
participation  interests  held by  the Fund  at  fair value,  which approximates
market value.  In  valuing  a participation  interest,  Mitchell  Hutchins  will
consider  the following  factors, among others:  (i) the  characteristics of the
participation interest, including  the cost, size,  interest rate, period  until
next  interest rate reset,  maturity and base lending  rate of the participation
interest, the terms and  conditions of the loan  and any related agreements  and
the  position of  the loan  in the borrower's  debt structure;  (ii) the nature,
adequacy and value of the collateral, including the Trust's rights, remedies and
interests with  respect to  the collateral;  (iii) the  creditworthiness of  the
borrower based on an evaluation of its financial condition, financial statements
and information about the borrower's business, cash flows, capital structure and
future  prospects;  (iv) the  market for  the participation  interest, including
price quotations  for and  trading  in the  participation interest  and  similar
participation  interests or instruments and  the market environment and investor
    
 
                                       5

- --------------------------------------------------------------------------------
attitudes  toward  the   participation  interest   or  participation   interests
generally;   (v)   the  quality   and   creditworthiness  of   any  intermediary
participants; and (vi) general economic or market conditions.
 
RESTRICTED AND ILLIQUID SECURITIES
 
Each Fund may not invest more than 10% of its net assets in illiquid securities,
including repurchase agreements that have  an effective maturity of longer  than
seven  days  and securities  that are  illiquid by  virtue of  the absence  of a
readily available  market  or  legal  or  contractual  restrictions  on  resale.
Securities  that have  legal or  contractual restrictions  on resale  but have a
readily available  market  are not  considered  illiquid for  purposes  of  this
limitation.  Repurchase  agreements  subject  to demand  are  deemed  to  have a
maturity equal to the notice period.
 
     Historically, illiquid  securities  have  included  securities  subject  to
contractual  or  legal  restrictions  on  resale  because  they  have  not  been
registered under the Securities Act of 1933, as amended (the 'Securities  Act'),
securities  that are otherwise not  readily marketable and repurchase agreements
having a  maturity of  longer than  seven days.  Securities that  have not  been
registered  under the Securities Act often are referred to as private placements
or restricted securities and  are purchased directly from  the issuer or in  the
secondary  market. Mutual  funds do not  typically hold a  significant amount of
these restricted  or other  illiquid  securities because  of the  potential  for
delays in resale and uncertainty in valuation. Limitations on resale may have an
adverse  effect on the  marketability of portfolio securities  and a mutual fund
might be unable to dispose of  restricted or other illiquid securities  promptly
or  at  reasonable prices  and  might thereby  experience  difficulty satisfying
redemptions within  seven  days. A  mutual  fund  also might  have  to  register
restricted  securities  in  order to  dispose  of them  resulting  in additional
expense and delay. Adverse market conditions  could impede a public offering  of
securities.
 
     In  recent years, however,  a large institutional  market has developed for
certain securities that are not  registered under the Securities Act,  including
repurchase   agreements,   commercial  paper,   foreign   securities,  municipal
securities and corporate bonds and  notes. Institutional investors depend on  an
efficient  institutional market in which the unregistered security can be resold
readily or on an issuer's ability to honor a demand for repayment. The existence
of contractual  or legal  restrictions on  resale to  the general  public or  to
certain institutions may not be indicative of the liquidity of the investments.
 
   
     The  SEC has adopted Rule 144A under the Securities Act, which allows for a
broader  institutional  trading  market  for  securities  otherwise  subject  to
restriction  on  resale to  the general  public. Rule  144A establishes  a 'safe
harbor' from the registration requirements of the Securities Act for resales  of
certain   securities  to  qualified   institutional  buyers.  Mitchell  Hutchins
anticipates  that  the  market  for  certain  restricted  securities,  such   as
institutional  commercial paper,  will expand  further as  a result  of this new
regulation and the development of  automated systems for the trading,  clearance
and  settlement of unregistered securities of domestic and foreign issuers, such
as the  PORTAL  System  sponsored  by the  National  Association  of  Securities
Dealers, Inc.
    
 
   
     Mitchell Hutchins will monitor the liquidity of restricted securities under
the  supervision  of the  Board of  Trustees.  In reaching  liquidity decisions,
Mitchell Hutchins  will consider,  inter alia,  the following  factors: (i)  the
frequency  of trades  and quotes  for the security;  (ii) the  number of dealers
wishing to  purchase or  sell the  security and  the number  of other  potential
purchasers; (iii) dealer undertakings to make a market in the security; and (iv)
the nature of the security and of the

marketplace trades (e.g., the time needed to dispose of the security, the method
of soliciting offers and the mechanics of the transfer).
 
INVESTMENT RESTRICTIONS
 
The  following restrictions may not be changed  with respect to any Fund without
the approval  of the  majority  of outstanding  voting  securities of  the  Fund
(which, under the Act and the rules thereunder and as used in the Prospectus and
this  Statement of Additional  Information, means the  lesser of (i)  67% of the
shares of the Fund present at a meeting  if the holders of more than 50% of  the
outstanding  shares of the Fund  are present in person or  by proxy or (ii) more
than 50% of the  outstanding shares of the  Fund). Investment restrictions  that
involve  a maximum percentage of securities or assets shall not be considered to
be violated unless an excess over the percentage occurs immediately after and is
caused by  an  acquisition  or  encumbrance  of  securities  or  assets  of,  or
borrowings  by  or  on behalf  of,  a  Fund, with  the  exception  of borrowings
permitted by Investment Restriction (4). In applying the following restrictions,
the Trust will not treat  a guarantee as a security  issued by the guarantor  if
the value of all securities issued or guaranteed by the guarantor and owned by a
Fund does not exceed 10% of the Fund's total assets.
 
     The Trust may not, on behalf of any Fund:
 
          (1) Purchase for the Fund the securities of any one issuer, other than
     U.S.  Government securities, if immediately after the purchase more than 5%
     of the value of the  Fund's total assets would  be invested in the  issuer,
     except  that (a) up to 25% of the value of its total assets may be invested
     without regard to this 5% limitation  and (b) this 5% limitation shall  not
     apply   to   repurchase  agreements   collateralized  by   U.S.  Government
     securities.
 
          (2) Purchase securities if the purchase  would cause more than 25%  in
     the  aggregate of the  market value of the  total assets of  the Fund to be
     invested in the securities  of one or more  issuers having their  principal
     business  activity  in  the  same  industry,  provided  that  there  is  no
     limitation with respect to, and each Fund reserves freedom of action,  when
     otherwise  consistent  with  its investment  policies,  to  concentrate its
     investments  in  U.S.  Government   securities,  obligations  (other   than
     commercial  paper)  issued  or  guaranteed  by  U.S.  banks  and repurchase
     agreements  and  securities   loans  collateralized   by  U.S.   Government
     securities or such bank obligations.
 
          (3) Make loans, except through (a) the purchase of debt obligations in
     accordance   with  the  Fund's  investment   objective  and  policies,  (b)
     repurchase agreements  with banks,  brokers,  dealers and  other  financial
     institutions and (c) loans of securities.
 
          (4) Borrow money, except as a temporary or emergency measure, and then
     only  from banks  in amounts  not exceeding one-third  of the  value of the
     Fund's total assets. No purchases of securities will be made if  borrowings
     exceed 5% of the value of the Fund's assets.
 
          (5)  Mortgage,  pledge  or  hypothecate any  assets  except  to secure
     permitted borrowings.
 
          (6) Purchase real estate (excluding securities secured by real  estate
     or  interests therein), securities issued  by real estate investment trusts
     or limited partnerships,  commodities, commodity contracts  or oil, gas  or
     other mineral leases or exploration or development programs.
 
          (7)  Invest  in companies  for the  purpose  of exercising  control of
     management.

- --------------------------------------------------------------------------------
 
          (8) Act as an  underwriter of securities (except  as the Trust may  be
     deemed to be an underwriter under the Securities Act in connection with the
     purchase  and sale of  portfolio instruments in  accordance with the Fund's
     investment objective  and  management  policies),  purchase  securities  on
     margin  (except for  delayed delivery  or when-issued  transactions or such
     short term credits  as are  necessary for the  clearance of  transactions),
     make  short sales of securities, maintain a  short position or invest in or
     write puts, calls, or combinations thereof  (except that the Trust may,  on
     behalf of a Fund, acquire puts in connection with the acquisition of a debt
     instrument).
 
          (9)  Purchase the securities of any issuer, other than U.S. Government
     securities, if  the  purchase would  cause  more  than 10%  of  the  voting
     securities  of the issuer to be held by  the Fund, except that up to 25% of
     the value of the Fund's total assets may be invested without regard to this
     10% limitation.
 
          (10) Purchase warrants.
 
     Notwithstanding restriction (1) above, to the extent required by the  rules
of  the SEC, the Money Market Fund will not invest more than 5% of its assets in
the obligations of any one issuer.
 
PORTFOLIO TRANSACTIONS
 
   
Subject to the general  control of the Board  of Trustees, Mitchell Hutchins  is
responsible  for, makes  decisions with respect  to, and places  orders for, all
purchases and sales  of portfolio  securities for each  Fund. Mitchell  Hutchins
purchases  portfolio securities for the Fund  either directly from the issuer or
from dealers that specialize  in money market  instruments. These purchases  are
usually  without  the  payment  of brokerage  commissions.  In  making portfolio
investments, Mitchell Hutchins seeks to obtain  the best net price and the  most
favorable  execution  of orders.  To  the extent  that  the execution  and price
offered by more than  one dealer are comparable,  Mitchell Hutchins may, in  its
discretion,  effect  transactions  in  portfolio  securities  with  dealers that
provide the Trust with research advice or other services.
    
 
   
     Mitchell Hutchins  may  seek  to  obtain an  undertaking  from  issuers  of
commercial  paper or dealers selling commercial paper to consider the repurchase
of the securities from the  Money Market Fund prior  to their maturity at  their
original  cost plus interest,  interest sometimes being  adjusted to reflect the
actual maturity of the securities, if Mitchell Hutchins believes that the Fund's
anticipated need for liquidity makes this action desirable. Certain dealers, but
not issuers,  have charged  and may  in the  future charge  a higher  price  for
commercial  paper  where they  undertake to  repurchase  prior to  maturity. The
payment of a higher price  in order to obtain  this kind of undertaking  reduces
the  yield that might otherwise be received by the Fund on the commercial paper.
Mitchell Hutchins is authorized to pay a higher price for commercial paper where
it secures such an undertaking if Mitchell Hutchins believes that the prepayment
privilege is desirable to  assure the Fund's liquidity  and such an  undertaking
cannot otherwise be obtained.
    
 
   
     Investment  decisions for the  Funds are made  independently from those for
other investment companies and accounts advised by Mitchell Hutchins, which  may
invest  in the same securities as the Funds. When purchases or sales of the same
security are  made at  substantially the  same  time on  behalf of  those  other
investment  companies and  accounts, transactions are  averaged as  to price and
available investments  are allocated  as to  amount in  a manner  that  Mitchell
Hutchins  believes to  be equitable  to each  company or  account, including the
Funds. In some instances, this investment
    
 
                                       8

- --------------------------------------------------------------------------------
   
procedure may adversely affect the price paid or received by a Fund or the  size
of  the position obtained for  a Fund. To the  extent permitted by law, Mitchell
Hutchins may aggregate the securities  to be sold or  purchased for a Fund  with
those  to be sold or purchased for those other companies or accounts in order to
obtain best execution.
    
 
   
     The Fund will not engage in principal transactions with, acquire  portfolio
securities issued by or enter into repurchase agreements with, Mitchell Hutchins
or  any affiliated person thereof,  as defined in the  Act, except to the extent
permitted by the SEC.
    
 
     The Trust does not intend to  seek profits through short-term trading.  The
Funds'  annual  portfolio  turnover  will be  relatively  high,  but  the Funds'
portfolio turnover  is not  expected to  have  a material  effect on  their  net
income.  Each  Fund's  portfolio  turnover  rate  is  expected  to  be  zero for
regulatory reporting purposes.
 
                       PURCHASE AND REDEMPTION OF SHARES
 
PURCHASE AND REDEMPTION
 
Information on  how  to purchase  and  redeem Fund  shares  is included  in  the
Prospectus.
 
     Under  the Act, the Trust  may suspend the right  of redemption or postpone
the date of payment  upon redemption for  any period during  which the New  York
Stock  Exchange is  closed, other than  customary weekend  and holiday closings,
during which  trading  on  that  exchange is  restricted  or  during  which  (as
determined  by the SEC by rule or regulation) an emergency exists as a result of
which  disposal  or  valuation  of   portfolio  securities  is  not   reasonably
practicable  or for such other periods as the SEC may permit. The Trust may also
suspend or  postpone the  recordation of  the transfer  of its  shares upon  the
occurrence of any of the foregoing conditions. In addition, the Trust may redeem
shares  involuntarily  in  certain  other instances  if  the  Board  of Trustees
determines that failure to redeem may have material adverse consequences to  the
Trust's  shareholders in general. The Trust is obligated to redeem shares solely
in cash up to $250,000 or 1% of a Fund's net asset value, whichever is less, for
any one shareholder within  a 90-day period. Any  redemption beyond this  amount
also  will be in  cash unless the  Board of Trustees  determines that conditions
exist that  make  payment  of  redemption proceeds  wholly  in  cash  unwise  or
undesirable.  In such  a case, the  Trust may  make payment wholly  or partly in
securities or other property (known as 'redemption in kind'), valued in the same
way as the Trust determines net asset value. See 'Net Asset Value' below for  an
example  of when  such a  redemption or  form of  payment might  be appropriate.
Redemption in  kind is  not as  liquid as  a cash  redemption. Shareholders  who
receive  a  redemption in  kind may  incur  transaction costs  if they  sell the
securities or property  and may receive  less than the  redemption value of  the
securities  or property  upon sale, particularly  where the  securities are sold
prior to maturity.
 
   
NET ASSET VALUE
    
 
Each Fund's net asset value per share is calculated by dividing the total  value
of  the assets belonging to the Fund,  less the value of any liabilities charged
to the Fund,  by the total  number of Fund  shares outstanding (irrespective  of
class).  Assets belonging to the Fund consist of the consideration received upon
the issuance of  Fund shares  together with  all income,  earnings, profits  and
proceeds  derived from the  investment thereof, including  any proceeds from the
sale of investments,  any funds  or payments  derived from  any reinvestment  of
those proceeds and a
 
                                       9
 
<PAGE>
- --------------------------------------------------------------------------------
portion  of any general assets of the  Trust not belonging to a particular Fund.
Assets belonging to the Fund are charged with the direct liabilities of the Fund
and with a share of  the general liabilities of the  Trust allocated on a  daily
basis in proportion to the relative net assets of the Funds. Determinations made
in good faith and in accordance with generally accepted accounting principles by
the  Board of Trustees as to the allocation  of any assets or liabilities to the
Fund are conclusive.
 
     In computing the net asset  value of its shares  for purposes of sales  and
redemptions,  the Trust uses the amortized  cost method of valuation. Under this
method, the Trust values each Fund's portfolio securities at cost on the date of
purchase and thereafter  assumes a  constant proportionate  amortization of  any
discount  or premium until maturity of the security. As a result, the value of a
portfolio security for purposes of determining net asset value normally does not
change in  response to  fluctuating  interest rates.  While the  amortized  cost
method provides certainty in portfolio valuation, it may result in valuations of
a  Fund's portfolio securities that are higher or lower than the market value of
the securities.
 
     In connection with its  use of amortized cost  valuation, each Fund  limits
the  dollar weighted average maturity of its  portfolio to not more than 90 days
and does not purchase any instrument with a remaining maturity of more than  397
days.  The Board of Trustees also has established procedures, pursuant to a rule
promulgated by the  SEC, that are  intended to stabilize  each Fund's net  asset
value per share for purposes of sales and redemptions at $1.00. These procedures
include  the determination at  such intervals as the  Board deems appropriate of
the extent, if any, to which the Fund's net asset value per share calculated  by
using  available market quotations  deviates from $1.00 per  share. In the event
this deviation exceeds 1/2 of 1%, the Board will promptly consider what  action,
if  any,  should be  initiated. If  the Board  believes that  the amount  of any
deviation from the  Fund's $1.00 amortized  cost price per  share may result  in
material dilution or other unfair results to investors or existing shareholders,
it  will take such steps  as it considers appropriate  to eliminate or reduce to
the extent reasonably practicable  any dilution or  unfair results. These  steps
may  include redeeming  shares in kind,  selling portfolio  instruments prior to
maturity to realize  capital gains or  losses or to  shorten the Fund's  average
portfolio  maturity, reducing or withholding dividends  or utilizing a net asset
value per share determined by using available market quotations.

                     INVESTMENT ADVISORY AND OTHER SERVICES
 
   
INVESTMENT ADVISER AND ADMINISTRATOR
    
 
   
PaineWebber, the  Funds'  investment  adviser and  administrator,  and  Mitchell
Hutchins,  the  Funds' sub-adviser  and sub-administrator,  are located  at 1285
Avenue of the Americas, New York, New York 10019.
    
 
   
     Subject to the supervision and direction  of the Trust's Board of  Trustees
and   of  PaineWebber,  Mitchell  Hutchins  manages  each  Fund's  portfolio  in
accordance with  the  stated  policies  of the  Fund.  Mitchell  Hutchins  makes
investment  decisions for the Fund  and places the purchase  and sale orders for
portfolio transactions.  Mitchell  Hutchins  employs  a  professional  staff  of
portfolio  managers that draw upon a variety of sources for research information
for the Fund. In addition, Mitchell  Hutchins pays the salaries of all  officers
and  employees  who are  employed by  both  it and  the Trust,  maintains office
facilities,  furnishes  statistical  and   research  data,  clerical  help   and
accounting,  data processing, bookkeeping, internal  auditing and legal services
and  certain  other  services  required  by  the  Trust,  prepares  reports   to
shareholders  and  filings with  the  SEC and  state  Blue Sky  authorities, and

and  legal expenses  and costs  of maintenance  of Trust  existence, shareholder
services, printing of prospectuses and statements of additional information  for
regulatory  purposes or for distribution  to shareholders, shareholders' reports
and Trust meetings.
 
   
     The Investment Advisory and Administration  Agreement remains in effect  as
to  each Fund from year  to year, provided its  continuance is approved at least
annually by (i)  the Board of  Trustees or (ii)  the vote of  a majority of  the
outstanding voting securities of the Fund, provided further that in either event
the  continuance is  also approved  by a  majority of  the Trustees  who are not
'interested persons,'  as defined  in  the Act,  of  the Trust,  PaineWebber  or
Mitchell Hutchins, by vote cast in person at a meeting called for the purpose of
voting  on this approval. With respect to each Fund, the Investment Advisory and
Administration Agreement was  approved by  shareholders in  accordance with  the
terms  of the Act on  April 13, 1995. With respect  to each Fund, the Investment
Advisory and Administration Agreement is terminable without penalty, on 60 days'
written notice, by the Board of Trustees of the Trust, by vote of the holders of
a majority of such Fund's outstanding voting securities, as defined in the  Act,
or  by PaineWebber.  The Investment  Advisory and  Administration Agreement will
terminate  automatically,  as  to  the  relevant  Fund,  in  the  event  of  its
assignment, as defined in the Act and the rules thereunder.
    
 
   
     As compensation for PaineWebber's services rendered to the Trust, each Fund
pays  a fee, computed daily and paid monthly,  at an annual rate of .25% of such
Fund's average daily  net assets.  For the fiscal  years ended  April 30,  1993,
April  30, 1994 and April 30, 1995, the Government Securities Fund in respect of
its Institutional shares incurred  fees of $342,099,  $283,281 and $           ,
respectively,  to  Kidder Peabody  Asset Management,  Inc. ('KPAM'),  the Fund's
predecessor investment  adviser  and  administrator,  or  PaineWebber.  However,
during  these periods, KPAM  or PaineWebber voluntarily waived  a portion of its
fees in the amounts of $17,557, $0 and $        , respectively, and  voluntarily
paid  expenses of $8,081,  $21,554 and $         ,  respectively. For the fiscal
period from July 12, 1994 (commencement  of operations) through April 30,  1995,
the  Government Securities Fund in respect  of its Financial Intermediary shares
incurred fees of $         to KPAM or PaineWebber. However, KPAM or  PaineWebber
voluntarily  waived $       of its fee and voluntarily paid $       of expenses.
For the fiscal years ended  April 30, 1993, April 30,  1994 and April 30,  1995,
the  Money Market Fund in  respect of its Institutional  shares incurred fees of
$937,992, $798,786 and $        , respectively, to KPAM or PaineWebber. However,
during these periods, KPAM  or PaineWebber voluntarily waived  a portion of  its
fees  in the amounts of $44,626, $0 and $        , respectively, and voluntarily
paid expenses of $36,168, $3,470  and $          , respectively. For the  fiscal
period  from March 17, 1994 (commencement  of operations) through April 30, 1994
and for the fiscal year ended April  30, 1995, the Money Market Fund in  respect
of  its Financial Intermediary shares paid  fees of $1,644 and $      to KPAM or
PaineWebber. For the fiscal years ended April 30, 1993, April 30, 1994 and April
30, 1995, the  Treasury Securities Fund  incurred fees of  $25,578, $47,804  and
$            to KPAM  or  PaineWebber. However,  during  these periods,  KPAM or
PaineWebber voluntarily waived its  fees in the amounts  of $1,638, $40,467  and
$         , respectively, and voluntarily  paid expenses of $76,822, $68,730 and
$         , respectively. During  these periods described  above, there were  no
Financial Intermediary shares of the Treasury Securities Fund outstanding.
    
 
   
     PaineWebber has agreed that if in any fiscal year the aggregate expenses of
a  Fund (including fees  pursuant to the  Investment Advisory and Administration
Agreement but excluding interest, taxes,  brokerage and, with the prior  written
consent of the necessary state securities commissions,
    
 
                                       14

extraordinary  expenses)  exceed  the  expense limitation  of  any  state having
jurisdiction over  the Trust,  PaineWebber  will reimburse  the Trust  for  such
excess  expense. This expense reimbursement obligation  is limited to the amount
of PaineWebber's fees. Any expense  reimbursement will be estimated,  reconciled
and  paid  on  a monthly  basis.  The  most stringent  state  expense limitation
applicable to the Trust currently requires reimbursement of expenses in any year
that expenses exceed 2 1/2% of the first $30 million of the average daily  value
of a Fund's net assets, 2% of the next $70 million of the average daily value of
the  Fund's net assets  and 1 1/2% of  the remaining average  daily value of the
Fund's net assets. During  the fiscal period ended  April 30, 1995, each  Fund's
expenses did not exceed such limitations.
    
 
   
     PaineWebber shall not be liable for any error of judgment or mistake of law
or  for any loss suffered  by the Trust in connection  with the matters to which
the Investment Advisory and Administration Agreement relates, except for a  loss
resulting from willful misfeasance, bad faith or gross negligence on its part in
the  performance  of  its  duties  or  from  reckless  disregard  by  it  of its
obligations  and  duties  under  the  Investment  Advisory  and   Administration
Agreement.

FINANCIAL INTERMEDIARIES
 
The  Trust will  enter into an  agreement with each  financial intermediary that
purchases Financial Intermediary shares requiring it to provide support services
to  its  customers  who  beneficially  own  Financial  Intermediary  shares   in
consideration  of the Trust's  payment of .25%  (on an annualized  basis) of the
average daily net asset value of  the Financial Intermediary shares held by  the
financial intermediary for the benefit of its customers. These services include:
(i) aggregating and processing
 
                                       15
 
<PAGE>
- --------------------------------------------------------------------------------
   
purchase  and redemption  requests from customers  and placing  net purchase and
redemption orders with Kidder, Peabody; (ii) providing customers with a  service
that  invests the  assets of  their accounts  in Financial  Intermediary shares;
(iii) processing dividend payments from the  Trust on behalf of customers;  (iv)
providing  information  periodically  to customers  showing  their  positions in
Financial Intermediary shares; (v) arranging for bank wires; (vi) responding  to
customer   inquiries  relating  to  the  services  performed  by  the  financial
intermediary;  (vii)  providing   sub-accounting  with   respect  to   Financial
Intermediary shares beneficially owned by customers or the information necessary
for  sub-accounting; (viii) forwarding shareholder communications from the Trust
(such as  proxies,  shareholder  reports  and  dividend,  distribution  and  tax
notices)  to customers, if required  by law; and (ix)  other similar services if
requested by the Trust. For the fiscal  period from March 17, 1994 (the date  on
which  Financial Intermediary shares  were first outstanding)  through April 30,
1994 and for the  fiscal year ended  April 30, 1995, the  Trust paid $1,694  and
$      , respectively, with  respect to the Financial Intermediary shares of the
Money Market Fund to financial intermediaries.  For the fiscal period from  July
12,   1994  (the  date  on  which   Financial  Intermediary  shares  were  first
outstanding) through April 30, 1995, the Trust paid $        with respect to the
Financial Intermediary shares  of the  Government Securities  Fund to  financial
intermediaries. [The Trust has not yet made payments to financial intermediaries
with  respect to  the Financial Intermediary  shares of  the Treasury Securities
Fund.]
    
 
     The Trust's agreements  with financial  intermediaries are  governed by  an
Amended and Restated Shareholder Services Plan (the 'Plan') adopted by the Board
of  Trustees in connection  with the offering  of Financial Intermediary shares.
Pursuant to  the Plan,  the Board  of  Trustees review,  at least  quarterly,  a
written  report  of  the  amounts expended  under  the  Trust's  agreements with
financial intermediaries and the purposes for which the expenditures were  made.
In  addition,  the Trust's  arrangements with  financial intermediaries  must be
approved annually by  a majority of  the Trustees, including  a majority of  the
Trustees who are not 'interested persons' of the Trust as defined in the Act and
have  no  direct  or  indirect financial  interest  in  these  arrangements (the
'Disinterested Trustees').
 
     The Board of Trustees may  approve the Trust's arrangements with  financial
intermediaries  if,  based  on  information  provided  by  the  Trust's  service
contractors, there is a reasonable likelihood that the arrangements will benefit
the Trust and  its shareholders by  affording the Trust  greater flexibility  in
connection  with the servicing of  the accounts of the  beneficial owners of its
shares in an efficient manner. Any material amendment to the Funds' arrangements
with financial intermediaries  must be approved  by a majority  of the Board  of
Trustees  including a  majority of  the Disinterested  Trustees. So  long as the
Trust's arrangements with Financial Intermediaries are in effect, the  selection
and  nomination of the members of the  Board of Trustees who are not 'interested
persons' of  the  Trust,  as defined  in  the  Act, will  be  committed  to  the
discretion of those non-interested Trustees.
 
     Conflict  of interest restrictions may  apply to a financial intermediary's
receipt of compensation  paid by  a Fund in  connection with  the investment  of
fiduciary  funds  in  Financial Intermediary  shares.  Financial intermediaries,
including banks  regulated by  the Comptroller  of the  Currency and  investment
advisers  subject to  the jurisdiction  of the SEC,  the Department  of Labor or
state securities commissions, are urged  to consult their legal advisors  before
investing fiduciary funds in Financial Intermediary shares. See also 'Management
of the Trust -- Financial Intermediaries' in the Trust's prospectus.

                       DIVIDENDS, DISTRIBUTIONS AND TAXES
 
   
Each Fund is treated as a separate  entity for federal income tax purposes,  has
qualified for the fiscal year ended April 30, 1995 to be treated as a 'regulated
investment company' under the Internal Revenue Code of 1986, as amended, and has
elected  or intends to elect this treatment  for each year. Provided that a Fund
distributes at least  90% of its  net investment income  and net realized  short
    
 
                                       17
 
<PAGE>
- --------------------------------------------------------------------------------
term  capital gains, a Fund, if it  qualifies as a regulated investment company,
will not be liable  for federal income  taxes to the  extent its net  investment
income  and its net long term and short term realized capital gains, if any, are
distributed to its shareholders.
 
     Although each  Fund expects  to be  relieved of  all or  substantially  all
federal  income taxes, depending on  the extent of its  activities in states and
localities in  which  its  offices  are  maintained,  in  which  its  agents  or
independent  contractors are located  or in which  it is otherwise  deemed to be
conducting business, that portion of a  Fund's income that is treated as  earned
in any such state or locality could be subject to state and local tax. Any taxes
paid  by  a Fund  would  reduce the  amount of  income  and gains  available for
distribution to shareholders.
 
     While each  of the  Funds does  not expect  to realize  any net  long  term
capital  gains, any such net realized gains  will be distributed as described in
the Prospectus. These distributions ('capital  gain dividends') will be  taxable
to shareholders as long term capital gains, regardless of how long a shareholder
has  held Fund  shares, and will  be designated  as capital gain  dividends in a
written notice mailed by the Trust to shareholders after the close of the Fund's
taxable year.
 
     If a shareholder fails to furnish a correct taxpayer identification number,
fails to report fully dividend or interest income, or fails to certify that  the
shareholder  has provided a correct taxpayer  identification number and that the
shareholder is not subject to withholding,  then the shareholder may be  subject
to   a  31%  'backup  withholding'  tax   with  respect  to  (i)  dividends  and
distributions and  (ii) the  proceeds  of any  redemptions  of Fund  shares.  An
individual's  taxpayer  identification  number  is his  or  her  social security
number. The 31% 'backup  withholding' tax is  not an additional  tax and may  be
credited against a taxpayer's regular federal income tax liability.
 
     The  foregoing is  only a summary  of certain  tax considerations generally
affecting the Funds and their shareholders  and is not intended as a  substitute
for  careful tax planning. Shareholders are  urged to consult their tax advisers
with specific reference to their own  tax situations, including their state  and
local tax liabilities.
 
                               YIELD INFORMATION
 
The  'current  yields'  and  'effective yields'  are  calculated  separately for
Institutional shares  and  Financial  Intermediary  shares  of  each  Fund.  The
seven-day  current yield for each class of  shares of each Fund is calculated by
determining the net change in the value of a hypothetical preexisting account in
the Fund having a balance of one share of the class involved at the beginning of
the period, dividing the net change by the value of the account at the beginning
of the period to obtain the base period return, and multiplying the base  period
return  by 365/7. The net change in the value of an account in the Fund includes
the value of additional shares purchased with dividends from the original  share
and dividends declared on the original share and any such additional shares, net
of  all fees charged to all shareholder  accounts in proportion to the length of
the base period and the Fund's average account size, but does not include  gains
and  losses  or  unrealized  appreciation  and  depreciation.  In  addition,  an
effective annualized yield quotation may be computed on a compounded basis  with
respect  to each class of shares  by adding 1 to the  base period return for the
class involved (calculated as described above), raising the sum to a power equal
to 365/7 and subtracting 1 from the result. Similarly, based on the calculations
described above, 30-day (or one-month) yields  and effective yields may also  be

     Yields  fluctuate and  any quotation of  yield should not  be considered as
representative of  the future  performance of  a Fund.  Since yields  fluctuate,
yield  data cannot  necessarily be  used to  compare an  investment in  a Fund's
shares with bank deposits, savings accounts and similar investment  alternatives
that  often provide an agreed  or guaranteed fixed yield  for a stated period of
time. Shareholders  should remember  that performance  and yield  are  generally
functions  of  the kind  and quality  of  the investments  held in  a portfolio,
portfolio maturity, operating expenses, and market conditions. Any fees  charged
by  financial  intermediaries with  respect  to investing  customer  accounts in
Financial  Intermediary  shares  of  a  Fund  will  not  be  included  in  yield
calculations;  these fees, if  charged, would reduce the  actual yield from that
quoted.
 
                             DESCRIPTION OF SHARES
 
The Trust does  not currently  intend to  hold annual  meetings of  shareholders
except  as required by the Act or other applicable law. These laws under certain
circumstances provide  shareholders with  the right  to call  for a  meeting  of
shareholders  to consider  the removal  of one or  more Trustees.  To the extent
required by law,  the Trust will  assist in shareholder  communication in  these
matters.
 
     As  stated in the Prospectus, holders of Institutional shares and Financial
Intermediary shares will vote in the aggregate and not by class on all  matters,
except   where  otherwise  required  by  law  and  except  that  only  Financial
Intermediary shares will be entitled to vote  on matters submitted to a vote  of
shareholders   pertaining   to   the   Trust's   arrangements   with   Financial
Intermediaries. See  'Management  of  the  Fund  --  Financial  Intermediaries.'
Further,  shareholders  of  a Fund  and  of the  other  Funds will  vote  in the
aggregate and not by Fund except as otherwise required by law or when the  Board
of  Trustees  determines that  the  matter to  be  voted upon  affects  only the
interests of the  shareholders of a  particular Fund. Rule  18f-2 under the  Act
provides  that any matter required to be submitted by the provisions of that Act
or applicable  state  law, or  otherwise,  to  the holders  of  the  outstanding
securities  of an investment  company such as  the Trust shall  not be deemed to
have been effectively acted upon unless approved by the holders of a majority of
the outstanding shares of each Fund  affected by the matter. Rule 18f-2  further
provides  that a Fund  shall be deemed to  be affected by a  matter unless it is
clear that the interests of  each Fund in the matter  are identical or that  the
matter  does not affect any interest of  the Fund. Under that Rule, the approval
of an investment advisory  agreement or any change  in a fundamental  investment
policy  would be effectively acted upon with  respect to a Fund only if approved
by the holders of a majority of  the outstanding voting securities of the  Fund.
That  Rule, however,  also provides  that the  ratification of  the selection of
independent accountants, the  approval of principal  underwriting contracts  and
the election of Trustees are not subject to the separate voting requirements and
may  be effectively acted upon by  shareholders of the investment company voting
without regard to the Fund.
 
SHAREHOLDER AND TRUSTEE LIABILITY
 
The Trust is an entity of the  type commonly known as a 'Massachusetts  business
trust,'  which  is the  form in  which  many mutual  funds are  organized. Under
Massachusetts  law,   shareholders  of   such  a   trust  may,   under   certain
circumstances,  be held personally liable as partners for the obligations of the
trust. The  Trust's  Declaration of  Trust  contains an  express  disclaimer  of
shareholder  liability  for acts  or obligations  of the  Trust. Notice  of this
disclaimer will normally be  given in each  agreement, obligation or  instrument
entered  into or executed by the Trust or the Trustees. The Declaration of Trust
provides   for   indemnification   by   the   relevant   Fund   for   any   loss
 
                                       19
 
<PAGE>
- --------------------------------------------------------------------------------
suffered  by  a  shareholder as  a  result of  an  obligation of  the  Fund. The
Declaration of Trust also  provides that the Trust  shall, upon request,  assume
the  defense of any claim made against any shareholder for any act or obligation
of the Trust and satisfy any judgment  thereon. Thus, the risk of a  shareholder
incurring  financial  loss on  account of  shareholder  liability is  limited to
circumstances in which a  Fund is unable to  meet its obligations. The  Trustees
believe  that,  in  view  of  the  above,  the  risk  of  personal  liability of
shareholders is not material.

                                   APPENDIX:
                             DESCRIPTION OF RATINGS
 
Set  forth below are  descriptions of the ratings  of Moody's Investors Service,
Inc. ('Moody's'), Standard &  Poor's Ratings Group  ('S&P') and Fitch  Investors
Services,  Inc. ('Fitch'), which  represent their opinions as  to the quality of
the securities that they  undertake to rate. It  should be emphasized,  however,
that  ratings  are relative  and subjective  and are  not absolute  standards of
quality.
 
DESCRIPTION OF S&P CORPORATE BOND RATINGS:
 
     AAA -- Bonds rated AAA  have the highest rating assigned  by S&P to a  debt
obligation. Capacity to pay interest and repay principal is extremely strong.
 
     AA  -- Bonds rated AA have a very strong capacity to pay interest and repay
principal and differ from the highest rated issues only in small degree.
 
DESCRIPTION OF MOODY'S CORPORATE BOND RATINGS:
 
     Aaa -- Bonds that  are rated Aaa  are judged to be  the best quality.  They
carry  the smallest degree of  investment risk and are  generally referred to as
'gilt-edge.' Interest payments are protected by a large or exceptionally  stable
margin and principal is secure. While the various protective elements are likely
to  change, these changes as  can be visualized are  most unlikely to impair the
fundamentally strong position of these issues.
 
     Aa -- Bonds that are Aa are judged to be of high quality by all  standards.
Together with the Aaa group they comprise what are generally known as high grade
bonds.  They are rated lower  than the best bonds  because margins of protection
may not be as large as in  Aaa securities or fluctuation of protective  elements
may be of greater amplitude or there may be other elements present that make the
long  term risks appear somewhat larger  than in Aaa securities. Moody's applies
the numerical modifiers 1, 2 and 3 to each generic rating classification from Aa
through B. The modifier 1 indicates that the security ranks in the higher end of
its generic rating category,  the modifier 2 indicates  a mid-range ranking  and
the  modifier 3 indicates that  the issue ranks in the  lower end of its generic
rating category.
 
DESCRIPTION OF S&P COMMERCIAL PAPER RATINGS:
 
     Commercial paper  rated A-1  by S&P  indicates that  the degree  of  safety
regarding  timely payment  is either overwhelming  or very  strong. Those issues
determined to possess overwhelming safety characteristics are denoted A-1+.
 
DESCRIPTION OF MOODY'S COMMERCIAL PAPER RATINGS:
 
     The rating  Prime-1 is  the  highest commercial  paper rating  assigned  by
Moody's.   Issuers  rated  Prime-1  (or  related  supporting  institutions)  are
considered to have a  superior capacity for repayment  of short term  promissory
obligations.
 
DESCRIPTION OF FITCH'S SHORT TERM RATINGS:
 
     Fitch  employs the  rating F-1+ to  indicate issues regarded  as having the
strongest degree of  assurance for timely  payment. The rating  F-1 reflects  an
assurance of timely payment only slightly less in degree than issues rated F-1+.
 
     Various of the rating agencies utilize rankings within categories indicated
by  a + or  -  . The Trust in accordance  with industry practice, recognize such
rankings within categories as  gradations, viewing for  example S&P's rating  of
A-1+ and A-1 - as being in S&P's highest rating category.

ITEM 27. INDEMNIFICATION
 
     Reference is  made  to Article  IV  of Registrant's  Amended  and  Restated
Declaration of Trust filed as Exhibit 1(b) to this Registration Statement.
 
     Insofar  as indemnification for liability  arising under the Securities Act
of 1933,  as amended  (the 'Securities  Act'), may  be permitted  for  Trustees,
officers  and  controlling  persons  of  Registrant  pursuant  to  provisions of
Registrant's Declaration of  Trust, or  otherwise, Registrant  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 Registrant  of  expenses
incurred  or paid by a Trustee, officer,  or controlling person of Registrant in
the successful defense on  any action, suit or  proceeding) is asserted by  such
Trustee,  officer or controlling person in  connection with the securities being
registered, Registrant 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.
