          This Prospectus sets forth concisely information about the above-
          referenced Funds. Please read this Prospectus carefully before

          A Statement of Additional Information dated April 1, 1996, has
          been filed with the Securities and Exchange Commission ("SEC") and may
          be obtained upon request and without charge by writing the
          Distributor, SEI Financial Services Company (the "Distributor"), at
          680 East Swedesford Road, Wayne, Pennsylvania 19087-1658, or by
          calling 1-800-342-5734. The Statement of Additional Information is
          incorporated into this Prospectus by reference.     
              
          SEI Asset Allocation Trust (the "Trust") is an open-end management
          investment company consisting of the following five separate
          diversified investment portfolios (each a "Fund" and, together, the
          "Funds"): Diversified Conservative Income Fund, Diversified
          Conservative Fund, Diversified Moderate Growth Fund, Diversified
          Growth Fund and Diversified U.S. Stock Fund. Each Fund offers
          investors a convenient means of investing in shares of certain mutual
          funds (the "Underlying Portfolios") managed by SEI Financial
          Management Corporation ("SFM" or the "Adviser") according to certain
          predetermined percentage ranges. Each Fund offers two classes of
          shares, Class A Shares and Class D Shares. Class A Shares are offered
          primarily to tax-advantaged retirement accounts. Class D Shares are
          offered to tax-advantaged and other accounts through banks, broker-
          dealers and other financial institutions that have entered into
          arrangements with the Distributor to sell Class D Shares to their
          customers. Class D Shares differ from Class A Shares primarily in the
          allocation of certain distribution, shareholder servicing and transfer
          agent expenses, and in the range and types of shareholder services
          offered to investors. THIS PROSPECTUS OFFERS BOTH CLASS A SHARES AND
          CLASS D SHARES OF THE FUNDS.      
          ----------------------------------------------------------------------

          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.

          ----------------------------------------------------------------------

          THE TRUST'S SHARES ARE NOT DEPOSITS OR OBLIGATIONS OF, OR GUARANTEED
          OR ENDORSED BY, ANY BANK. THE TRUST'S SHARES ARE NOT FEDERALLY INSURED
          BY THE FEDERAL DEPOSIT INSURANCE CORPORATION, THE FEDERAL RESERVE
          BOARD OR ANY OTHER GOVERNMENT AGENCY. INVESTMENT IN THE FUNDS INVOLVES
          RISK, INCLUDING POSSIBLE LOSS OF THE PRINCIPAL AMOUNT INVESTED.

THE EXAMPLE SHOULD NOT BE CONSIDERED A REPRESENTATION OF PAST OR FUTURE
EXPENSES. ACTUAL EXPENSES MAY BE GREATER OR LESS THAN THOSE SHOWN. The purpose
of the expense tables and example is to assist the investor in understanding the
various costs and expenses that may be directly or indirectly borne by investors
in Class A Shares of each Fund. A person who purchases shares through an account
with a financial institution may be charged separate fees by that institution in
addition to those set forth above. The information set forth in the foregoing
table and example relates to the Class A Shares. Class A Shares are subject to
the same management and advisory expenses as Class D Shares, but are subject to
different distribution, shareholder servicing and transfer agent expenses.
Additional information may be found under "The Adviser and Manager of the Funds"
and "Distribution of Fund Shares."

THE EXAMPLE SHOULD NOT BE CONSIDERED A REPRESENTATION OF PAST OR FUTURE
EXPENSES. ACTUAL EXPENSES MAY BE GREATER OR LESS THAN THOSE SHOWN. The purpose
of the expense tables and example is to assist the investor in understanding the
various costs and expenses that may be directly or indirectly borne by investors
in Class D Shares of each Fund. A person who purchases shares through an account
with a financial institution may be charged separate fees by that institution in
addition to those set forth above. The information set forth in the foregoing
table and example relates to the Class D Shares. Class D Shares are subject to
the same management and advisory expenses as Class A Shares, but are also
subject to different distribution, shareholder servicing and transfer agent
expenses. Additional information may be found under "The Adviser and Manager of
the Funds" and "Distribution of Fund Shares."      

Long-term Class D shareholders may pay more than the economic equivalent of the
maximum front-end sales charges otherwise permitted by the Rules of Fair
Practice of the NASD.

* The Funds will purchase only Class A Shares of the Underlying Portfolios. The
expense ratios of the Class A Shares of the Underlying Portfolios shown above
reflect existing fee waivers and expense reimbursement arrangements that may be
discontinued at any time. Absent these fee waivers on the Class A Shares of the
Underlying Portfolios, these expense ratios would be higher.      
    
Investors in the Funds should recognize that they may invest directly in the
Underlying Portfolios and that, by investing in Underlying Portfolios through
the Funds, they will bear not only their proportionate share of the expenses of
the Funds (including operating costs and investment advisory and administrative
fees to the extent the Adviser has not elected to waive such fees), but will
also indirectly bear similar expenses of the Underlying Portfolios. Investors
that purchase shares of the Funds through managed account programs who pay
separate advisory fees for asset allocation services should recognize that the
combined expenses of the program and the Funds (including the expenses charged
by the Underlying Portfolios) may involve greater fees and expenses than those
present in other types of investments without the benefit of professional asset
allocation recommendations. In addition, a shareholder of a Fund's Shares will
indirectly bear expenses paid by an Underlying Portfolio related to the
distribution of its shares, if any. In the case of Class D Shares, any Fund
distribution/shareholder servicing fees

shareholder servicing fees charged to any Underlying Portfolio in which the Fund
invests.  Currently, Class A Shares of the Underlying Portfolios are subject to
a .25% shareholder servicing fee.  See "Distribution of Fund Shares."      

INVESTMENT
OBJECTIVES AND
POLICIES OF THE
FUNDS___________________________________________________________________________

- --------------------------------------------------------------------------------
    
[SYMBOL APPEARS HERE]
                      
WHAT ARE INVESTMENT OBJECTIVES AND POLICIES?

A Fund's investment objective is a statement of what it seeks to achieve. It is
important to make sure that the investment objective matches your own financial
needs and circumstances. The investment policies section spells out the types of
mutual funds in which each Fund invests in attempting to meet its investment 
objective.

- --------------------------------------------------------------------------------
    
The Funds offer investors the opportunity to invest in certain of the Underlying
Portfolios, and are designed primarily for tax-advantaged retirement and other
long-term investment or savings accounts, including:  Individual Retirement
Accounts ("IRAs"), Simplified Employee Plans ("SEPs"), 403(b)(7) tax-sheltered
retirement plans for employees of non-profit organizations, 401(k) savings
plans, profit-sharing and money-purchase pension plans, and other corporate
pension and savings plans.      

    
          In order to achieve its investment objective, each Fund typically
invests a percentage of its assets among predetermined percentage ranges in
certain of the Underlying Portfolios, which are separately-managed series of the
following investment companies: SEI Institutional Managed Trust ("SIMT"), SEI
International Trust ("SIT") and SEI Liquid Asset Trust ("SLAT" and, together
with SIMT and SIT, the "Underlying Trusts"). The percentages reflect the extent
to which each Fund will invest in the particular market segment represented by
each Underlying Portfolio, and the varying degrees of potential investment risk
and reward represented by each Fund's investments in those market segments and
their corresponding Underlying Portfolios. The Adviser may alter these
percentage ranges when it deems appropriate. The assets of each Fund will be
allocated among each of the Underlying Portfolios in accordance with its
investment objective, the Adviser's outlook for the economy, the financial
markets and the relative market valuations of the Underlying Portfolios. In
addition, in order to meet liquidity needs or for temporary defensive purposes,
each Fund may invest its assets directly in cash, money market securities, or
other instruments, including stock or bond index futures and options thereon.
The investment objective of each Fund is set forth below. Each Fund's investment
objective is a fundamental policy, and may not be changed without shareholder
approval. There can be no assurance that the Funds will achieve their stated
objectives.    
    
DIVERSIFIED CONSERVATIVE INCOME FUND      
    
The DIVERSIFIED CONSERVATIVE INCOME FUND seeks to provide current income and an
opportunity for capital appreciation through limited participation in domestic
equity markets.  In general, relative to the other Funds, the Diversified
Conservative Income Fund should offer investors the potential for a medium to
high level of income and the potential for a medium level of capital growth,
while subjecting investors to a medium level of principal risk.  The Fund will
invest in the following Underlying Portfolios within the percentage ranges set
forth below:

GENERAL INVESTMENT
POLICIES OF THE FUNDS___________________________________________________________
     
    
The Funds will attempt to achieve their investment objectives by purchasing
shares of the Underlying Portfolios within the percentage ranges set forth
above. The SEC has issued an exemptive order to the Trust dated December 20,
1995 (the "Order"), permitting the Funds to acquire up to 100% of the Shares of
any of the Underlying Portfolios under certain conditions. Absent this Order,
the Investment Company Act of 1940 (the "1940 Act") would substantially limit
the ability of the Funds and Underlying Portfolios to engage in these
transactions.    
    
          In order to meet liquidity needs, or for temporary defensive purposes,
the Funds may purchase money market securities or other short-term debt
instruments rated in one of the top two categories by a nationally recognized
statistical rating organization ("NRSRO") at the time of purchase or, if not
rated, determined to be of comparable quality by the Adviser. To the extent that
a Fund is engaged in temporary defensive investing, it will not be pursuing its
investment objective. See "Description of Permitted Investments and Risk Factors
of the Underlying Portfolios."      
    
          In addition to purchasing shares of the Underlying Portfolios, the
Funds may use futures contracts and options in order to remain effectively fully
invested in proportions consistent with SFM's current asset allocation strategy
in an efficient and cost effective manner. Specifically, each Fund may enter
into futures contracts and options thereon provided that the aggregate deposits
required on these contracts do not exceed 5% of the Fund's total assets.      

    
          Futures contracts and options may also be used to reallocate the
Funds' assets among asset categories while minimizing transaction costs, to
maintain cash reserves while simulating full investment, to facilitate trading
or to seek higher investment returns or simulate full investment when futures
contract is priced attractively or is otherwise considered more advantageous
than the underlying security or index. While futures contracts and options can
be used as leveraged instruments, the Funds will not use futures contracts or
options to leverage their portfolios.     

PORTFOLIO TURNOVER
OF THE FUNDS           _________________________________________________________
    
Each Fund's portfolio turnover rate (i.e., the rate at which the Fund buys and
                                     ----                                     
sells shares of the Underlying Portfolios) is not expected to exceed 10%.  Asset
reallocation decisions typically will occur only once every quarter.  However,
if market conditions warrant, SFM may make more frequent reallocation decisions,
which will result in a higher portfolio turnover rate.  The Funds will purchase
or sell shares of the Underlying Portfolios: (a) to accommodate purchases and
redemptions of each Fund's shares; (b) in response to market or other economic
conditions; and (c) to maintain or modify the allocation of each Fund's assets
among the Underlying Portfolios within the percentage limits described above or
as altered by SFM from time to time.  It is important to note, however, that the
Portfolio turnover rate of certain of the Underlying Portfolios (i.e., the rate
                                                                 ----          
at which the Underlying Portfolios buy and sell securities), may exceed 100%.
Such a turnover rate may result in higher transaction costs and may result in
additional tax consequences for shareholders (including the Funds).      

                                                                              11

RISK FACTORS
OF THE FUNDS            ________________________________________________________
               
Prospective investors in the Funds should consider the following factors:

 .         Any investment in a mutual fund involves risk and, although the Funds
          invest in a number of Underlying Portfolios, this practice does not
          eliminate investment risk;
    
 .         Investing in the Underlying Portfolios through the Funds involves
          certain additional expenses and tax results that would not be present
          in a direct investment in the Underlying Portfolios;      

 .         Under certain circumstances, an Underlying Portfolio may determine to
          make payment of a redemption request by a Fund wholly or partly by a
          distribution in kind of securities from its portfolio, instead of
          cash, in accordance with the rules of the SEC. In such cases, the
          Funds may hold securities distributed by an Underlying Portfolio until
          the Adviser determines that it is appropriate to dispose of such
          securities;
    
 .         Certain Underlying Portfolios may: invest a portion of their assets in
          foreign securities; enter into forward currency transactions; lend
          their portfolio securities; enter into stock index, interest rate and
          currency futures contracts, and options on such contracts; engage in
          other types of options transactions; make short sales; purchase zero
          coupon and payment-in-kind bonds; and engage in various other
          investment practices. Further information about these investment
          policies and practices can be found under "Investment Objectives and
          Policies of the Underlying Portfolios" and "Description of Permitted
          Investments and Risk Factors of the Underlying Portfolios" in this
          Prospectus and in the Trust's Statement of Additional Information, and
          in the prospectuses of each of the Underlying Portfolios;      

 .         The Diversified Growth Fund can invest as much as 15% of its assets in
          the SIMT High Yield Bond Portfolio. As a result, this Fund will be
          subject to the risks associated with high yield investing;
   
    

    
 .         Certain Funds invest at least 5% and can invest as much as 25% of
          their assets in the SIT International Fixed Income Portfolio, which
          invests primarily in foreign fixed-income securities. Certain other
          Funds invest at least 15% and can invest as much as 45% of their
          assets in Underlying Portfolios that invest primarily in foreign
          equity securities. These investments will subject the Funds to risks
          associated with investing in foreign securities; and      
    
 .         The officers and trustees of the Trust also serve as officers and
          trustees of the Underlying Trusts. In addition, the Adviser to each
          Fund serves as investment adviser to certain of the Underlying
          Portfolios. Conflicts may arise as these persons seek to fulfill their
          fiduciary responsibilities at both levels.      


    
     
INVESTMENT LIMITATIONS
OF THE FUNDS            ________________________________________________________
    
The following investment limitations are fundamental for each Fund, and may not
be changed without shareholder approval.      
    
1.        Each Fund will concentrate its investments in mutual fund shares. 
     
    
2.        Each Fund may not borrow money in an amount exceeding 33 1/3% of the
          value of its total assets, provided that, for purposes of this
          limitation, investment strategies which either obligate a Fund to
          purchase securities or require a Fund to segregate assets are not
          considered to be borrowings. Except where a Fund has borrowed money
          for temporary purposes in amounts not exceeding 5% of its assets,
          asset coverage of 300% is required for all borrowings.      
    
Each Fund is subject to further fundamental and non-fundamental restrictions
which are described in the Trust's Statement of Additional Information.

SIMT LARGE CAP
GROWTH PORTFOLIO       The SIMT Large Cap Growth Portfolio seeks to provide
                       capital appreciation. Under normal market conditions, the
                       Portfolio will invest at least 65% of its total assets in
                       equity securities of large companies (i.e., companies
                       with market capitalizations of more than $1 billion)
                       which, in the advisers' opinion, possess significant
                       growth potential. Any remaining assets may be invested in
                       fixed income securities or in equity securities of
                       smaller companies that the Portfolio's advisers believe
                       are appropriate in light of the Portfolio's objective.
                       Equity securities include common stock, preferred stock,
                       warrants or rights to subscribe to common stock and, in
                       general, any security that is convertible into or
                       exchangeable for common stock. Fixed income securities
                       must be rated investment grade or better, i.e., rated at
                                                                 ----

SIMT LARGE CAP
VALUE PORTFOLIO        The SIMT Large Cap Value Portfolio seeks to provide long-
                       term growth of capital and income. Under normal market
                       conditions, the Portfolio will invest at least 65% of its
                       total assets in a diversified portfolio of high quality,
                       income-producing common stocks of large companies (i.e.,
                                                                          ----
                       companies with market capitalizations of more than $1
                       billion) which, in the advisers' opinion, are undervalued
                       in the marketplace at the time of purchase. In general,
                       the advisers characterize high quality securities as
                       those that have above-average reinvestment rates. The
                       advisers also consider other factors, such as earnings
                       and dividend growth prospects as well as industry outlook
                       and market share. Equity securities include common stock,
                       preferred stock, warrants or rights to subscribe to
                       common stock and, in general, any security that is
                       convertible into or exchangeable for common stock. Any
                       remaining assets may be invested in investment grade
                       fixed income securities.      

    
SIMT SMALL CAP
GROWTH PORTFOLIO       The SIMT Small Cap Growth Portfolio seeks to provide
                       long-term capital appreciation. Under normal market
                       conditions, the Portfolio will invest at least 65% of its
                       total assets in the equity securities of smaller growth
                       companies (i.e.,companies with market capitalizations
                                  ----
                       of less than $1 billion) which, in the advisers' opinion,
                       are in an early stage or transitional point in their
                       development and have      

                                                                              13

                       demonstrated or have the potential for above average
                       capital growth. The advisers will select companies that
                       have the potential to gain market share in their
                       industry, achieve and maintain high and consistent
                       profitability or produce increases in earnings. The
                       advisers also seek companies with strong company
                       management and superior fundamental strength.    
   
                              Small capitalization companies have the potential
                       to show earnings growth over time that is well above the
                       growth rate of the overall economy. Any remaining assets
                       may be invested in the equity securities of more
                       established companies that the advisers believe may offer
                       strong capital appreciation potential due to their
                       relative market position, anticipated earnings growth,
                       changes in management or other similar opportunities.
                       Equity securities include common stock, preferred stock,
                       warrants and rights to subscribe to common stock and, in
                       general, any security that is convertible into or
                       exchangeable for common stock.    
    
                              In order to meet liquidity needs, or for temporary
                       defensive purposes, the Portfolio may invest all or a
                       portion of its assets in common stocks of larger, more
                       established companies, fixed income securities, cash or
                       money market securities. Fixed income securities will
                       only be purchased if they are rated investment grade or
                       better. Investment grade bonds include securities rated
                       at least BBB by S&P or Baa by Moody's. Money market
                       securities will only be purchased if they have been given
                       one of the two top ratings by an NRSRO, or if not rated,
                       determined to be of comparable quality by the Portfolio's
                       advisers.

                       Portfolio will invest at least 65% of its total assets in
                       the equity securities of smaller companies (i.e.,
                                                                   -----
                       companies with market capitalizations of less than $1
                       billion) which, in the advisers' opinion, have prices
                       that appear low relative to certain fundamental
                       characteristics such as earnings, book value, or return
                       on equity. Any remaining assets may be invested in fixed
                       income securities or equity securities of larger, more
                       established companies that the Portfolio's advisers
                       believe are appropriate in light of the Portfolio's
                       objective. Equity securities include common stock,
                       preferred stock, warrants and rights to subscribe to
                       common stock and, in general, any security that is
                       convertible into or exchangeable for common stock. Fixed
                       income securities must be rated investment grade or
                       better, i.e., rated at least BBB by S&P or Baa by

SIT INTERNATIONAL
EQUITY PORTFOLIO       The SIT International Equity Portfolio seeks to provide
                       long-term capital appreciation by investing primarily in
                       a diversified portfolio of equity securities of non-U.S.
                       issuers. Under normal circumstances, at least 65% of the
                       Portfolio's assets will be invested in equity securities
                       of non-U.S. issuers located in at least three countries
                       other than the United States. The Portfolio may enter
                       into forward foreign currency contracts as a hedge
                       against possible variations in foreign exchange rates. A
                       forward foreign currency contract is a commitment to
                       purchase or sell a specified currency, at a specified
                       future date, at a specified price. The Portfolio may
                       enter into forward foreign currency contracts to hedge a
                       specific security transaction or to hedge a portfolio
                       position. These contracts may be bought or sold to
                       protect the Portfolio, to some degree, against a possible
                       loss resulting from an adverse change in the relationship
                       between foreign currencies and the U.S. dollar. The
                       Portfolio may also invest in options on currencies.      

                              Securities of non-U.S. issuers purchased by the
                       Portfolio may be purchased in foreign markets, on U.S.
                       registered exchanges, the over-the-counter market or in
                       the form of sponsored or unsponsored American Depositary
                       Receipts ("ADRs") traded on registered exchanges or
                       NASDAQ or sponsored or unsponsored European Depositary
                       Receipts ("EDRs"), Continental Depositary Receipts
                       ("CDRs") or Global Depositary Receipts ("GDRs"). The
                       Portfolio will typically invest in equity securities
                       listed on recognized foreign exchanges, but may also
                       invest in securities traded in over-the-counter markets.
                       The Portfolio expects its investments to emphasize both
                       large and intermediate capitalization companies.

                              The Portfolio expects to be fully invested in its
                       primary investments described above, but may invest up to
                       35% of its total assets in U.S. or non-U.S. cash
                       reserves; money market instruments; swaps;

                                                                              14

                       rated at time of purchase A or higher by S&P or Moody's,

                       high-grade commercial paper; and other long- and short-
                       term debt instruments which are rated at the time of
                       purchase A or higher by S&P or Moody's and which, with
                       respect to such long-term debt instruments, are within
                       397 days of their maturity.      

                              The Portfolio is also permitted to acquire
                       floating and variable rate securities, purchase
                       securities on a when-issued or delayed delivery basis and
                       invest up to 10% of its total assets in illiquid
                       securities. Although permitted to do so, the Portfolio
                       does not currently intend to invest in securities issued
                       by passive foreign investment companies or to engage in
                       securities lending.
   
                              For temporary defensive purposes, when an adviser
                       determines that market conditions warrant, the Portfolio
                       may invest up to 50% of its assets in the U.S. and non-
                       U.S. money market instruments described above and other
                       U.S. and non-U.S. long- and short-term debt instruments
                       which are rated BBB or higher by S&P or Baa or higher by
                       Moody's at the time of purchase, or are determined by the
                       advisers to be of comparable quality; may hold a portion
                       of such assets in cash; and may invest in securities of
                       supranational entities which are rated A or higher by S&P
                       or Moody's at the time of purchase, or are determined by

SIT EMERGING MARKETS
EQUITY PORTFOLIO       The SIT Emerging Markets Equity Portfolio seeks to
                       provide capital appreciation by investing primarily in a
                       diversified portfolio of equity securities of emerging
                       market issues. Under normal circumstances, at least 65%
                       of the Portfolio's assets will be invested in equity
                       securities of emerging market issuers. Under normal
                       market conditions, the Portfolio maintains investments in
                       at least six emerging market countries and does not
                       invest more than 35% of its total assets in any one
                       emerging market country. For these purposes, the
                       Portfolio defines an emerging market country as any
                       country the economy and market of which the World Bank or
                       the United Nations considers to be emerging or
                       developing. The Portfolio's advisers consider emerging
                       market issuers to be companies the securities of which
                       are principally traded in the capital markets of emerging
                       market countries: that derive at least 50% of their total
                       revenue from either goods produced or services rendered
                       in emerging market countries, regardless of where the
                       securities of such companies are principally traded; or
                       that are organized under the laws of and have a principal
                       office in an emerging market country. In addition to its
                       primary investments, described above, the Portfolio may
                       invest up to 35% of its total assets in debt securities,
                       including up to 5% of its total assets in debt securities
                       rated below investment grade. These debt securities will
                       include debt securities of emerging market companies.
                       Bonds rated below investment grade are often referred to
                       as "junk bonds." Such securities involve greater risk of
                       default or price declines than investment grade
                       securities.      

                              The Portfolio may invest in certain debt
                       securities issued by the governments of emerging market
                       countries that are or may be eligible for conversion into
                       investments in emerging market companies under debt
                       conversion programs sponsored by such governments.

                              The Portfolio may invest up to 10% of its total
                       assets in illiquid securities. The Portfolio's advisers
                       believe that carefully selected investments in joint
                       ventures, cooperatives, partnerships, private placements,
                       unlisted securities and other similar situations
                       (collectively, "special situations") could enhance the
                       Portfolio's capital appreciation potential. Investments
                       in special situations may be illiquid, as determined by
                       the Portfolio's advisers based on criteria approved by
                       the Portfolio's Board of Trustees. To the extent these
                       investments are deemed illiquid, the Portfolio's
                       investment in them will be consistent with its 10%
                       restriction on investment in illiquid securities.

                              The Portfolio may invest up to 10% of its total
                       assets in shares of other investment companies.

                              The Portfolio may invest in futures contracts and
                       purchase securities on a when-issued or delayed delivery
                       basis. The Portfolio may also purchase and write options
                       to buy or sell futures contracts.

                              For temporary defensive purposes, when the
                       advisers determine that market conditions warrant, the
                       Portfolio may invest up to 20% of its total assets in the
                       equity securities of companies constituting the Morgan
                       Stanley Capital International Europe, Australia, Far East
                       Index (the "EAFE Index").

                                                                              15

                       These companies typically have larger average market
                       capitalizations than the emerging market companies in
                       which the Portfolio generally invests.
    
                              The Emerging Markets Equity Portfolio uses a
                       proprietary, quantitative asset allocation model created
                       by its sub-adviser. This model employs mean-variance
                       optimization, a process used in developed markets based
                       on modern portfolio theory and statistics. Mean-variance
                       optimization helps determine the percentage of assets to
                       invest in each country to maximize expected returns for a
                       given risk level. The Portfolio invests in those
                       countries that the advisers expect to have the highest
                       risk/reward tradeoff when incorporated into a total
                       portfolio context. The advisers attempt to construct a
                       portfolio of emerging market investments that
                       approximates the risk level of an internationally
                       diversified portfolio of securities in developed markets.
                       This "top-down" country selection is combined with
                       "bottom-up" fundamental industry analysis and stock
                       selection based on original research, publicly available
                       information, and company visits.      

                              The Portfolio's investments in emerging markets
                       can be considered speculative, and therefore may offer
                       higher potential for gains and losses than developed
                       markets of the world. With respect to any emerging
                       country, there is the greater potential for
                       nationalization, expropriation or confiscatory taxation,
                       political changes, government regulation, social
                       instability or diplomatic developments (including war)
                       which could affect adversely the economies of such
                       countries or investments in such countries. The economies
                       of developing countries generally are heavily dependent
                       upon international trade and, accordingly, have been and
                       may continue to be adversely affected by trade barriers,
                       exchange controls, managed adjustments in relative
                       currency values and other protectionist measures imposed
                       or negotiated by the countries with which they trade.

SIMT CORE FIXED
INCOME PORTFOLIO       The SIMT Core Fixed Income Portfolio seeks to provide
                       current income consistent with the preservation of
                       capital. Under normal market conditions, the Portfolio
                       will invests at least 65% of its total assets in fixed
                       income securities that are rated investment grade or
                       better, i.e., rated in one of the four highest rating
                               ----
                       categories by an NRSRO at the time of purchase, or, if
                       not rated, determined to be of comparable quality by the
                       advisers. Fixed income securities in which the Portfolio
                       may invest consist of: (i) corporate bonds and
                       debentures; (ii) obligations issued by the United States
                       Government, its agencies and instrumentalities; (iii)
                       municipal securities of issuers located in all fifty
                       states, the District of Columbia, Puerto Rico and other
                       U.S. territories and possessions, consisting of municipal
                       bond, municipal notes, tax-exempt commercial paper and
                       municipal lease obligations; (iv) receipts involving U.S.
                       Treasury obligations; (v) mortgage-backed securities;
                       (vi) asset-backed securities; and (vii) zero coupon, pay-
                       in-kind or deferred payment securities.      
    
                              Any remaining assets may be invested in: (i)
                       interest-only and principal-only components of mortgage-
                       backed securities; (ii) mortgage dollar rolls; (iii)
                       securities issued on a when-issued and delayed-delivery
                       basis, including TBA mortgage-backed securities; (iv)
                       warrants; (v) money market securities; and (vi) Yankee
                       obligations. In addition, the Portfolio may purchase or
                       write options, futures (including futures on U.S.
                       Treasury obligations and Eurodollar instruments) and
                       options on futures.      
   
                              Duration is a measure of the expected life of a
                       fixed income security on a cash flow basis. Most debt
                       obligations provide interest payments and a final payment
                       at maturity. Some also have put or call provisions that
                       allow the security to be redeemed at specified dates
                       prior to maturity. Duration incorporates yield, coupon
                       interest payments, final maturity and call features into
                       a single measure. The advisers therefore consider it a
                       more accurate measure of a security's expected life and
                       sensitivity to interest rate changes than is the
                       security's term to maturity.    
   
                            The Portfolio invests in a portfolio with a 
                       dollar-weighted average duration that will, under normal
                       market conditions, stay within plus or minus 20% of what
                       the advisers believe to be the average duration of the
                       domestic bond market as a whole. The advisers base their
                       analysis of the average duration of the domestic bond
                       market on bond market indices which they believe to be
                       representative. The advisers currently use the Lehman
                       Aggregate Bond Index for this purpose.      
    
SIMT HIGH YIELD
BOND PORTFOLIO         The SIMT High Yield Bond Portfolio seeks to maximize
                       total return. Under normal market conditions, the
                       Portfolio will invest at least 65% of its total assets in
                       fixed-income securities that are rated below investment
                       grade (i.e., rated below the top four rating

                       purchase), or, if not rated, are determined to be of
                       comparable quality by the Portfolio's advisers. Below
                       investment grade securities are commonly referred to as
                       "junk bonds," and generally entail increased credit and
                       market risk. The achievement of the Portfolio's
                       investment objective may be more dependent on the
                       advisers' own credit analysis than would be the case if
                       the Portfolio invested in higher rated securities. There
                       is no bottom limit on the ratings of high yield
                       securities that may be purchased or held by the
                       Portfolio.      

                              The Portfolio may invest in all types of fixed
                       income securities issued by domestic and foreign issuers,
                       including: (i) mortgage-backed securities; (ii) asset-
                       backed securities; (iii) zero coupon, pay-in-kind or
                       deferred payment securities; and (iv) variable and
                       floating rate instruments.
   
                              Any assets of the Portfolio not invested in the
                       fixed income securities described above may be invested
                       in: (i) convertible securities; (ii) preferred stocks;
                       (iii) equity securities; (vi) investment grade fixed
                       income securities; (v) money market securities; (vi)
                       securities issued on a when-issued and delayed-delivery
                       basis, including TBA mortgage-backed securities; (vii)
                       forward foreign currency contracts; and (viii) Yankee
                       obligations. In addition, the Portfolio may purchase or
                       write options, futures and options on futures. The
                       advisers may vary the average maturity of the securities
                       in the Portfolio without limit, and there is no
                       restriction on the maturity of any individual security.
                           
    
                              The securities purchased by the Portfolio may be
                       rated in the lowest rating category for fixed income
                       securities. Bonds rated C by Moody's are the lowest rated
                       class of bonds, and issues so rated can be regarded as
                       having extremely poor prospects of ever attaining any
                       real investment standing. Bonds are rated D by S&P when
                       the issue is in payment default, or the obligor has filed
                       for bankruptcy. The D rating is used when interest or
                       principal payments are not made on the date due, even if
                       the applicable grace period has not expired, unless S&P
                       believes that such payments will be made during such
                       grace period. The ratings established by each NRSRO
                       represents its opinions of the safety of principal and
                       interest payments (and not the market risk) of bonds and
                       other debt securities they undertake to rate at the time
                       of issuance. Ratings are not absolute standards of
                       quality and may not reflect changes in an issuer's
                       creditworthiness. Accordingly, although the Portfolio's
                       advisers will consider ratings, they will perform their
                       own analyses and will not rely principally on ratings.
                       The advisers will consider, among other things, the price
                       of the security and the financial history and condition,
                       the prospects and the management of an issuer in
                       selecting securities for the Portfolio.      
    
                              RISK FACTORS RELATING TO INVESTING IN LOWER RATED
                       SECURITIES -- The High Yield Bond Portfolio may invest in
                       lower rated securities. Fixed income securities are
                       subject to the risk of an issuer's ability to meet
                       principal and interest payments on the obligation (credit
                       risk), and may also be subject to price volatility due to
                       such factors as interest rate sensitivity, market
                       perception of the creditworthiness of the issuer and
                       general market liquidity (market risk). Lower rated or
                       unrated (i.e., high yield) securities are more likely
                                ----
                       to react to developments affecting market and credit risk
                       than are more highly rated securities, which primarily
                       react to movements in the general level of interest
                       rates. The market values of fixed-income securities tend
                       to vary inversely with the level of interest rates.
                       Yields and market values of high yield securities will
                       fluctuate over time, reflecting not only changing
                       interest rates but the market's perception of credit
                       quality and the outlook for economic growth. When
                       economic conditions appear to be deteriorating, medium to
                       lower rated securities may decline in value due to
                       heightened concern over credit quality, regardless of the
                       prevailing interest rates. Investors should carefully
                       consider the relative risks of investing in high yield
                       securities and understand that such securities are not
                       generally meant for short-term investing.      
    
                              The high yield market is relatively new and its
                       growth has paralleled a long period of economic expansion
                       and an increase in merger, acquisition and leveraged
                       buyout activity. Adverse economic developments can
                       disrupt the market for high yield securities, and
                       severely affect the ability of issuers, especially highly
                       leveraged issuers, to service their debt obligations or
                       to repay their obligations upon maturity which may lead
                       to a higher incidence of default on such securities. In
                       addition, the secondary market for high yield securities,
                       which is concentrated in relatively few market makers,
                       may not be as liquid as the secondary market for more
                       highly rated securities. As a result, the Portfolio could
                       find it more difficult to sell these securities or may be
                       able to sell the securities only at prices lower than if
                       such securities were widely traded. Furthermore, the
                       Portfolio may experience difficulty in valuing certain
                       securities at certain times. Prices realized upon the
                       sale of such lower rated or unrated securities, under
                       these circumstances, may be less than the prices used in
                       calculating the Portfolio's net asset value.      

                              Lower rated or unrated debt obligations also
                       present risks based on payment expectations. If an issuer
                       calls an obligation for redemption, the Portfolio may
                       have to replace the security with a lower yielding
                       security, resulting in a decreased return for investors.
                       If the Portfolio experiences unexpected
                                                                              
                                                                              17

                       net redemptions, it may be forced to sell its higher
                       rated securities, resulting in a decline in the overall
                       credit quality of the Portfolio's investment portfolio
                       and increasing the exposure of the Portfolio to the risks
                       of high yield securities.

    
SIT INTERNATIONAL
FIXED INCOME
PORTFOLIO              The SIT International Fixed Income Portfolio seeks to
                       provide capital appreciation and current income through
                       investment primarily in high quality, non-U.S. dollar
                       denominated government and corporate fixed income
                       securities or debt obligations. Under normal
                       circumstances, at least 65% of the Portfolio's assets
                       will be invested in high quality foreign government and
                       foreign corporate fixed income securities or debt
                       obligations of issuers located in at least three
                       countries other than the United States.      
    
                              The fixed income securities in which the SIT
                       International Fixed Income Portfolio may invest are: (i)
                       fixed income securities issued or guaranteed by a foreign
                       government or one of its agencies, authorities,
                       instrumentalities or political subdivisions; (ii) fixed
                       income securities issued or guaranteed by supranational
                       entities; (iii) fixed income securities issued by foreign
                       corporations; (iv) convertible securities; and (v) fixed
                       income securities issued by foreign banks or bank holding
                       companies. All such investments will be in high quality
                       securities denominated in various currencies, including
                       the European Currency Unit. High quality securities are
                       rated in one of the highest four rating categories by an
                       NRSRO or, of comparable quality at the time of purchase
                       as determined by the adviser.      
    
                              Any remaining assets of the Portfolio will be
                       invested in any of the fixed income securities described
                       above, obligations issued or guaranteed as to principal
                       and interest by the United States Government, its
                       agencies or instrumentalities ("U.S. Government
                       Securities"), swaps, options and futures. The Portfolio
                       may also purchase and write options to buy or sell
                       futures contracts. The Portfolio also may enter into
                       forward currency contracts, purchase securities on a 
                       when-issued or delayed delivery basis and engage in short
                       selling. Furthermore, although the Portfolio will
                       concentrate its investments in relatively developed
                       countries, the Portfolio may invest up to 5% of its
                       assets in similar securities or debt obligations that are
                       denominated in the currencies of developing countries and
                       that are of comparable quality to such securities and
                       debt obligations at the time of purchase as determined by
                       the adviser.      

                              There are no restrictions on the average maturity
                       of the securities held by the Portfolio or the maturity
                       of any single instrument. Maturities may vary widely
                       depending on the adviser's assessment of interest rate
                       trends and other economic and market factors. In the
                       event a security owned by the Portfolio is downgraded
                       below the rating categories discussed above, the adviser
                       will review the situation and take appropriate action
                       with regard to the security.
    
                              The Portfolio is a non-diversified investment
                       company, as defined in the 1940 Act, which means that
                       more than 5% of its assets may be invested in one or more
                       issuers, although the adviser does not intend to invest
                       more than 5% of its assets in any single issuer with the
                       exception of securities which are issued or guaranteed by
                       a national government. Since a relatively high percentage
                       of assets of the Portfolio may be invested in the
                       obligations of a limited number of issuers, the value of
                       shares of the Portfolio may be more susceptible to any
                       single economic, political or regulatory occurrence than
                       the shares of a diversified investment company would be.
                       The Portfolio intends to satisfy the diversification
                       requirements necessary to qualify as a regulated
                       investment company under the Internal Revenue Code of
                       1986, as amended (the "Code"), by limiting its
                       investments so that, at the close of each quarter of the
                       taxable year, (a) not more than 25% of the market value
                       of the Portfolio's total assets is invested in the
                       securities (other than U.S. Government Securities) of a
                       single issuer and (b) at least 50% of the market value of
                       the Portfolio's total assets is represented by (i) cash
                       and cash items, (ii) U.S. Government Securities and (iii)
                       other securities limited in respect to any one issuer to
                       an amount not greater in value than 5% of the market
                       value of the Portfolio's total assets and to not more
                       than 10% of the outstanding voting securities of such
                       issuer.      

                                 For temporary defensive purposes, when the
                       adviser determines that market conditions warrant, the
                       Portfolio may invest up to 100% of its assets in U.S.
                       dollar denominated fixed income securities or debt
                       obligations and the following domestic and foreign money
                       market instruments: government obligations, certificates
                       of deposit, bankers' acceptances, time deposits,
                       commercial paper, short-term corporate debt issues and
                       repurchase agreements. The Portfolio may hold a portion
                       of its assets in cash for liquidity purposes.

SLAT PRIME
OBLIGATION PORTFOLIO   The SLAT Prime Obligation Portfolio seeks to preserve
                       principal value and maintain a high degree of liquidity
                       while providing current income. The Portfolio invests
                       exclusively in: (i) commercial paper rated at least A-1
                       by S&P or Prime-1 by Moody's at the time of investment
                       or, if not rated, determined by the Adviser to be of
                       comparable quality; (ii) obligations (including
                       certificates of deposit, time deposits, bankers'
                       acceptances and bank notes) of U.S. commercial banks that
                       are members of the Federal Reserve System or the Federal
                       Deposit Insurance Corporation or savings and loan
                       institutions, which banks or institutions have total
                       assets of $500 million or more as shown on their most
                       recent public financial statements at the time of
                       investment, provided that such obligations are rated in
                       the top two short-term rating categories by two or more
                       NRSROs, or one NRSRO if only one NRSRO has rated the
                       security at the time of investment or, if not rated,
                       determined by the adviser to be of comparable quality;
                       (iii) short-term corporate obligations rated AAA or AA by
                       S&P or Aaa or Aa by Moody's at the time of investment or,
                       if not rated, determined by the adviser to be of
                       comparable quality; (iv) short-term obligations issued by
                       state and local governmental issuers, which are rated, at
                       the time of investment, by at least two NRSROs in one of
                       the two highest municipal bond rating categories, and
                       which carry yields that are competitive with those of
                       other types of money market instruments of comparable
                       quality; (v) U.S. Treasury obligations or obligations
                       issued or guaranteed as to principal and interest by
                       agencies or instrumentalities of the U.S. Government; and
                       (vi) repurchase agreements involving any of the foregoing
                       obligations.      

                              The Portfolio may invest in restricted securities
                       and may invest up to 10% of its net assets in illiquid
                       securities. Rule 144A Securities and Section 4(2)
                       commercial paper that meet the criteria established by
                       the Board of Trustees of the Trust may be considered
                       liquid.

                              The Portfolio may only purchase securities with a
                       remaining maturity of 365 days or less, and, as a matter
                       of non-fundamental policy, will maintain a dollar-
                       weighted average portfolio maturity of 90 days or less.
                       An investment in the Portfolio is neither insured or
                       guaranteed by the U.S. Government and there can be no
                       assurance that the Portfolio will be able to maintain a
                       stable net asset value of $1.00 per share.

GENERAL INVESTMENT
POLICIES OF THE
UNDERLYING PORTFOLIOS      _____________________________________________________

Borrowing              Each Underlying Portfolio, except the SLAT Prime
                       Obligation Portfolio, may borrow money to meet
                       redemptions for temporary or emergency purposes. A
                       Portfolio will not purchase securities while its
                       borrowings exceed 5% of its total assets.

Common Stocks          Each Underlying Portfolio, except the SLAT Prime
                       Obligation, SIMT Core Fixed Income, SIMT High Yield Bond
                       and SIT International Fixed Income Portfolios, will
                       invest in common stocks; provided, however, that the
                       Underlying Portfolios may only invest in such securities
                       if they are listed on registered exchanges or actively
                       traded in the over-the-counter market.

Forward Foreign
Currency Contracts     The Underlying Portfolios, except the SIMT Core Fixed
                       Income, SIMT Large Cap Growth, SIMT Small Cap Growth,
                       SIMT Large Cap Value, SIMT Small Cap Value, and SLAT
                       Prime Obligation Portfolios may purchase forward foreign
                       currency contracts.
    
Illiquid
Securities             Each Underlying Portfolio's investment in illiquid
                       securities will be limited to 15% of its net assets (10%
                       with respect to the SLAT Prime Obligation, SIT
                       International Equity, SIT Emerging Markets Equity, and
                       SIT International Fixed Income Portfolios).      
    
Investment Company
Securities             Each Underlying Portfolio, except the SLAT Prime
                       Obligation Portfolio, may purchase investment company
                       securities, which will result in additional layering of
                       expenses. However, there are legal limits on the amount
                       of such securities that may be acquired by an Underlying
                       Portfolio. As a condition to the Order that was granted
                       to the Trust by the SEC, no Underlying Portfolio in which
                       a Fund invests may purchase: (i) more than 3 percent of
                       the total outstanding voting securities of another
                       registered investment company; (ii) securities issued by
                       such investment company if such securities have an      
                                                                                
                                                                              19
<PAGE>
 
                       aggregate value of more than 5 percent of the total
                       assets of such Underlying Portfolio; or (iii) securities
                       issued by such investment company and all other
                       investment companies if such securities have an aggregate
                       value of more than 10 percent of the total assets of such
                       Underlying Portfolio.
    
Investment Grade
Debt Securities        Each Underlying Portfolio, except the SLAT Prime
                       Obligation Portfolio, may invest in investment grade debt
                       securities. Interest payments and principal security for
                       securities rated in the fourth highest rating category
                       (i.e., BBB by S&P or Baa by Moody's) appear adequate
                        -----
                       for the present, but certain protective elements may be
                       lacking or may be characteristically unreliable over any
                       great length of time. Such securities lack outstanding
                       investment characteristics and in fact have speculative
                       characteristics as well.      
    
Money Market
Instruments            In order to meet liquidity needs or for temporary
                       defensive purposes, the Underlying Portfolios may hold
                       cash reserves and invest in money market instruments
                       (including securities issued or guaranteed by the U.S.
                       Government, its agencies or instrumentalities, repurchase
                       agreements, certificates of deposit and bankers'
                       acceptances issued by banks or savings and loan
                       associations having net assets of at least $500 million
                       as of the end of their most recent fiscal year, high-
                       grade commercial paper and other short-term debt
                       securities) rated at the time of purchase in the top two
                       categories by an NRSRO, or, if not rated, determined by
                       the adviser to be of comparable quality at the time of
                       purchase. To the extent any Underlying Portfolio is
                       engaged in temporary defensive investing, it will not be
                       pursuing its investment objective.      

Options and
Futures                Each Underlying Portfolio, except the SLAT Prime
                       Obligation Portfolio, may purchase or sell options,
                       futures and options on futures. Risks associated with
                       investing in options and futures may include lack of a
                       liquid secondary market, trading restrictions which may
                       be imposed by an exchange and government regulations
                       which may restrict trading.

Securities
Lending                Each Underlying Portfolio, except the SLAT Prime
                       Obligation Portfolio, may lend its securities to
                       qualified investors for the purpose of realizing
                       additional income.
    
     
   
U.S. Dollar
Denominated
Securities of          
Foreign Issuers        Each Underlying Portfolio, except the SLAT Prime
                       Obligation, SIMT Small Cap Growth, and SIMT Core 
                       Fixed Income Portfolios, may invest in U.S. dollar
                       denominated securities of foreign issuers, including
                       American Depositary Receipts that are traded on
                       registered exchanges or listed on NASDAQ.    

    
Warrants               Consistent with any applicable state law limitations,
                       each Underlying Portfolio, except the SLAT Prime
                       Obligation, SIT International Fixed Income and SIT
                       International Equity Portfolios, may purchase warrants
                       in order to increase total return.      

When-Issued and
Delayed-Delivery
Securities             The Underlying Portfolios may purchase securities on a
                       when-issued or delayed-delivery basis.


For additional information regarding the permitted investments of the Underlying
Portfolios see the "Description of Permitted Investments and Risk Factors of the
Underlying Portfolios" in this Prospectus, the Trust's Statement of Additional
Information, the "Description of Permitted Investments and Risk Factors" in the
Underlying Portfolios' Prospectuses and the "Description of Permitted
Investments" in the Underlying Portfolios' Statements of Additional Information.

                                                                              20

RISK FACTORS OF THE
UNDERLYING PORTFOLIOS      _____________________________________________________

From time to time, the Underlying Portfolios may experience relatively large
purchases or redemptions due to asset allocation decisions made by the Adviser
for its clients, including the Trust.  These transactions may have a material
effect on the Underlying Portfolios, since Underlying Portfolios that experience
redemptions as a result of reallocations may have to sell portfolio securities
and because Underlying Portfolios that receive additional cash will have to
invest it.  While it is impossible to predict the overall impact of these
transactions over time, there could be adverse effects on portfolio management
to the extent that Underlying Portfolios may be required to sell securities at
times when they would not otherwise do so, or receive cash that cannot be
invested in an expeditious manner.  There may be tax consequences associated
with purchases and sales of securities, and such sales may also increase
transaction costs.  The Adviser is committed to minimizing the impact of these
transactions on the Underlying Portfolios to the extent it is consistent with
pursuing the investment objectives of its asset allocation clients.  The Adviser
will monitor the impact of asset allocation decisions on the Underlying
Portfolios and, where practicable, a Fund will, at any one time, only redeem
shares of an Underlying Portfolio to reduce its allocation to that particular
Portfolio in increments of up to 5% (e.g., from 20% to 15%), except where such
redemptions are to meet Fund shareholder redemption requests.  The Adviser will
nevertheless face conflicts in fulfilling its responsibilities because of the
possible differences between the interests of its asset allocation clients
(including shareholders of the Funds) and the interests of the Underlying
Portfolios.      

FUNDAMENTAL LIMITATIONS
OF THE UNDERLYING
PORTFOLIOS                 _____________________________________________________

Each Underlying Portfolio, except the SIT International Fixed Income Fund, may
not invest more than 5% of its assets in the securities of a single issuer.
(This limitation applies to 75% of the assets of the SIMT and SIT Portfolios,
and does not apply to securities issued by the U.S. Government, its agencies or
instrumentalities.)

          Each Underlying Portfolio may not purchase securities which would
cause more than 25% of such Portfolio's assets to be invested in the securities
of issuers conducting business in the same industry. (This limitation does not
apply to investments in securities issued by the U.S. Government, its agencies
or instrumentalities and, with respect to the SLAT Prime Obligation Portfolio,
obligations of domestic banks.)
    
          The foregoing percentage limitations relating to the Underlying
Portfolios' investment limitations will apply at the time of the purchase of the
security by an Underlying Portfolio. Additional fundamental and non-fundamental
investment limitations are set forth in the Underlying Portfolios' Prospectuses
and Statements of Additional Information.      

THE ADVISER AND MANAGER
OF THE FUNDS               _____________________________________________________

- --------------------------------------------------------------------------------
    
[SYMBOL APPEARS HERE]     

INVESTMENT ADVISER

A Fund's investment adviser manages the investment activities and is responsible
for the performance of the Fund.  The adviser executes investment strategies
based on an assessment of economic and market conditions, and determines the
appropriate allocation of the Fund's assets among the Underlying Portfolios.
- --------------------------------------------------------------------------------
    
Under an Investment Advisory Agreement with the Trust, SEI Financial Management
Corporation ("SFM" or the "Adviser")  acts as the investment adviser to each
Fund.  Under the Agreement, the Adviser will provide its proprietary asset
allocation services to the Funds, and will exercise investment discretion over
the assets of the Funds.  The Adviser will monitor the allocation of each Fund's
assets, and will be responsible for supervising compliance with each Fund's
fundamental investment objectives and policies.  Although it is expected that
each Fund will typically be fully invested in the Underlying Portfolios, the
Adviser may, from time to time, direct the investment of each Fund's cash
balances in money market securities or in other instruments, including stock or
bond index futures and options thereon.  For its investment advisory services to
the Trust, the Adviser is entitled to a fee, which is calculated daily and paid
monthly, at an annual rate of .10% of each Fund's average daily net assets.  The
Adviser has voluntarily agreed to waive this fee for the foreseeable future.
This waiver may be terminated by the Adviser at any time in its sole 
discretion.      
    
          Under an Administration Agreement with the Trust, SFM also provides
the Trust with overall management services, regulatory reporting, all necessary
office space, equipment, personnel, and facilities, and acts as dividend
disbursing agent and shareholder servicing agent. For these services to the
Funds, SFM is entitled to a fee, which is calculated daily and paid monthly, 
     

                                                                              21
<PAGE>
    
at an annual rate of .20% of the average daily net assets of each Fund.  SFM has
agreed to waive its management fee for the foreseeable future.  This waiver is
voluntary and may be discontinued at any time in SFM's sole discretion.    
    
     The Adviser is a wholly-owned subsidiary of SEI Corporation ("SEI"), a
financial services company located in Wayne, Pennsylvania. The principal
business address of the Adviser is 680 East Swedesford Road, Wayne, Pennsylvania
19087-1658. SEI was founded in 1968, and is a leading provider of investment
solutions to banks, institutional investors, investment advisers and insurance
companies. Affiliates of the Adviser have provided consulting advice to
institutional investors for more than 20 years, including advice regarding the
selection and evaluation of investment advisers and advice regarding asset
allocation strategies. The Adviser currently serves as manager or administrator
to more than 26 investment companies including more than 220 portfolios, which
investment companies had more than $51 billion in assets as of September 30,
1996.      
    
      Investment and asset allocation decisions for the Funds are made by a
committee within SFM.

SEI FINANCIAL
MANAGEMENT
CORPORATION            In addition to serving as the Trust's Adviser, SFM serves
                       as investment adviser to each Underlying Portfolio except
                       the SIT International Fixed Income and SLAT Prime
                       Obligation Portfolios.      

                              Under its advisory agreement with each Underlying
                       Portfolio for which it serves as investment adviser (an
                       "Underlying SEI Portfolio"), the Adviser is authorized to
                       make investment decisions for the assets of the
                       Underlying SEI Portfolio, and to continuously review,
                       supervise and administer the Underlying SEI Portfolio's
                       investment program.
    
                              In addition, the Adviser has general oversight
                       responsibility for the investment sub-advisory services
                       provided to the Underlying SEI Portfolios, including
                       formulating investment policies and analyzing economic
                       trends affecting the Underlying SEI Portfolios. The
                       Adviser is also responsible, subject to the review and
                       approval of the Trust's Board of Trustees, for setting
                       each Underlying SEI Portfolio's overall investment
                       strategy, managing the allocation of assets among the
                       Underlying SEI Portfolio's sub-advisers, directing and
                       evaluating the investment services provided by the sub-
                       advisers, including their adherence to the investment
                       objectives and policies and investment performance of
                       each Underlying SEI Portfolio and determining when to
                       hire or replace a sub-adviser. In accordance with these
                       investment objective and policies, and under the
                       supervision of the Adviser and the Trust's Board of
                       Trustees, each sub-adviser is responsible for the day-to-
                       day investment management of all or a discrete portion of
                       the assets of an Underlying SEI Portfolio. The Adviser
                       and the sub-advisers are authorized to make investment
                       decisions for the Underlying SEI Portfolios and place
                       orders on behalf of the Underlying SEI Portfolios to
                       effect the investment decisions made.      
    
                              The Adviser has obtained an exemptive order from
                       the SEC that permits the Adviser, with the approval of
                       the Underlying Trusts' Boards of Trustees, to retain sub-
                       advisers for Underlying SEI Portfolios of SIMT and SIT
                       without submitting the sub-advisory agreement to a vote
                       of the Underlying SEI Portfolio's shareholders. The
                       exemptive relief also permits the non-disclosure of
                       amounts payable by the Adviser under such sub-advisory
                       agreements. Under this exemptive order, if one of the 
                       sub-advisers is terminated or departs from an Underlying
                       SEI Portfolio with multiple sub-advisers, the Underlying
                       SEI Portfolio will handle such termination or departure
                       in one of two ways. First, the Underlying SEI Portfolio
                       may propose that a new sub-adviser be appointed to manage
                       that portion of the Underlying SEI Portfolio's assets
                       managed by the departing sub-adviser. In this case, the
                       Underlying SEI Portfolio would be required to submit to
                       the Underlying SEI Portfolio's shareholders the
                       investment sub-advisory contract with the new sub-
                       adviser. In the alternative, the Underlying SEI Portfolio
                       may decide to allocate the departing sub-adviser's assets
                       among the remaining sub-advisers. This allocation would
                       not require a new investment sub-advisory contract, and
                       consequently no shareholder approval would be 
                       necessary.     
    
                              For its advisory services to the Underlying
                       Portfolios, the Adviser is entitled to a fee, which is
                       calculated daily and paid monthly, at an annual rate of
                       .40% of the average daily net assets of the SIMT Large
                       Cap Growth Portfolio, .35% of the average daily net
                       assets of the SIMT Large Cap Value Portfolio, .65% of the
                       average daily net assets of the SIMT Small Cap Growth and
                       Small Cap Value Portfolios, .475% of the average daily
                       net assets of the SIT International Equity Portfolio,
                       1.05% of the average daily net assets of the SIT Emerging
                       Markets Equity Portfolio, .275% of the average daily net
                       assets of the SIMT Core Fixed Income Portfolio, and
                       .4875% of the average daily net assets of the SIMT High
                       Yield Bond Portfolio.

DISTRIBUTION

                                                                              28

OF FUND SHARES             _____________________________________________________
    
SEI Financial Services Company (the "Distributor"), a wholly-owned subsidiary of
SEI, serves as each Fund's distributor pursuant to a distribution agreement (the
"Distribution Agreement") with the Trust.  The Trustees of the Trust have
adopted a distribution and shareholder service plan for the Trust's Class D
shares (the "Class D Plan") pursuant to Rule 12b-1 under the 1940 Act.      

          The Class D Plan provides for payments to the Distributor for
distribution-related services at an annual rate of .75% of each Fund's average
daily net assets attributable to Class D Shares. In addition, each Fund is
authorized to pay the Distributor a fee in connection with the ongoing servicing
of shareholder accounts owning such Class D Shares, calculated and payable
monthly, at the annual rate of .25% of the value of the average daily net assets
attributable to Class D Shares of the Fund.
    
          The distribution-related payments may be used by the Distributor to
provide initial and ongoing sales compensation to its investment executives and
to other broker-dealers and financial intermediaries in respect of sales of
Class D Shares, to compensate third parties for the provision of recordkeeping
and other distribution-related services relating to Class D Shares, and to pay
for advertising and promotional expenses in connection with the distribution of
Class D Shares. These advertising and promotional expenses may include: costs of
printing and mailing prospectuses, statements of additional information and
shareholder reports to prospective investors; preparation and distribution of
sales literature; advertising of any type; an allocation of other expenses of
the Distributor related to the distribution of Class D Shares; and payments to,
and expenses of, officers, employees or representatives of the Distributor, of
other broker-dealers, banks or other financial institutions, and of any other
persons who provide support services in connection with the distribution of the
Fund Shares.      
    
          The service fees payable to the Distributor may be used by the
Distributor to provide compensation to financial intermediaries for ongoing
service and/or maintenance of shareholder accounts with respect to Class D
Shares of the applicable Funds. Such shareholder services may include: telephone
service to shareholders, including acceptance of telephone inquiries and
transaction requests; acceptance and processing of written correspondence, new
account applications and subsequent purchases by check; mailing of
confirmations, statements and tax forms directly to shareholders; maintenance of
customer accounts, and acceptance of payment for trades by check, Federal
Reserve wire or Automatic Clearing House payment. In addition, Distributor shall
perform or supervise the performance by others of other shareholder services in
connection with the operations of the applicable Funds, as agreed from time to
time.      

          Payments under the Class D Plan are not tied exclusively to the
expenses for distribution or shareholder servicing activities actually incurred
by the Distributor or third parties, so that such payments may exceed expenses
actually incurred by the Distributor. The Trust's Board of Trustees will
evaluate the appropriateness of the Plan and its payment terms on a continuing
basis and in doing so will consider all relevant factors, including expenses
borne by the Distributor and amounts it receives under the Class D Plan.
    
          Periodically, the Distributor may waive a portion of the fees payable
to it under the Class D Plan in order to keep within certain sales charge limits
imposed by the Trust's SEC Order. Specifically, any Fund's
distribution/shareholder servicing fees will be reduced in an amount equal to
the Fund's pro rata portion of any shareholder servicing fees paid by any
           --- ----                                                      
Underlying Portfolio in which the Fund invests.      

          It is possible that an institution may offer different categories of
shares to its customers and thus receive different compensation with respect to
the different categories. These financial institutions may also charge separate
fees to their customers.

          The Distributor may, from time to time in its sole discretion,
institute one or more promotional incentive programs, which will be paid for by
the Distributor from the sales charge it receives or from any other source
available to it. Under any such program, the Distributor will provide
promotional incentives, in the form of cash or other compensation, including
merchandise, airline vouchers, trips and vacation packages, to all dealers
selling shares of the Funds. Such promotional incentives will be offered
uniformly to all shares of the Funds and also will be offered uniformly to all
dealers, predicated upon the amount of shares of the Funds sold by such dealer.

PERFORMANCE                _____________________________________________________

From time to time, the Funds may advertise yield and total return.  These
figures will be based on historical earnings and are not intended to indicate
future performance.  The yield of a Fund refers to the annualized income
generated by an investment in the Fund over a specified 30-day period.  The
yield is calculated by assuming that the same amount of income generated by the
investment during that period is generated in each 30-day period over one year
and is shown as a percentage of the investment.

          The total return of a Fund refers to the average compounded rate of
return to a hypothetical investment for designated time periods (including but
not limited to, the period from which the Fund commenced operations through the
specified date), assuming that the entire investment is redeemed at the end of
each period and assuming the reinvestment of all dividend and capital gain
distributions. The total return of a Fund may also be quoted as a dollar amount
or on an aggregate basis or an actual

                                                                              29

basis, without inclusion of any front-end or contingent sales charges, or with a
reduced sales charge in advertisements distributed to investors entitled to a
reduced sales charge.
    
          A Fund may periodically compare its performance to that of: (i) other
mutual funds tracked by mutual fund rating services (such as Lipper Analytical),
financial and business publications and periodicals; (ii) broad groups of
comparable mutual funds; (iii) unmanaged indices which may assume investment of
dividends but generally do not reflect deductions for administrative and
management costs; or (iv) other investment alternatives. The Fund may quote
Morningstar, Inc., a service that ranks mutual funds on the basis of risk-
adjusted performance, and Ibbotson Associates of Chicago, Illinois, which
provides historical returns of the capital markets in the U.S. The Fund may use
long-term performance of these capital markets to demonstrate general long-term
risk versus reward scenarios and could include the value of a hypothetical
investment in any of the capital markets. The Fund may also quote financial and
business publications and periodicals as they relate to fund management,
investment philosophy, and investment techniques.      

          The Fund may quote various measures of volatility and benchmark
correlation in advertising and may compare these measures to those of other
funds. Measures of volatility attempt to compare historical share price
fluctuations or total returns to a benchmark while measures of benchmark
correlation indicate how valid a comparative benchmark might be. Measures of
volatility and correlation are calculated using averages of historical data and
cannot be calculated precisely.

          For each Portfolio, the performance of Class A Shares will normally be
higher than the performance of the Class D shares of that Portfolio because of
the additional distribution, shareholder servicing and transfer agent expenses
charged to Class D Shares.

TAXES                      _____________________________________________________


- --------------------------------------------------------------------------------

 TAXES
 You must pay taxes on your Fund's earnings, whether you take your payments in
 cash or additional shares.
- --------------------------------------------------------------------------------

The following summary of federal income tax consequences is based on current tax
laws and regulations, which may be changed by legislative, judicial, or
administrative action. No attempt has been made to present a detailed
explanation of the federal, state, or local tax treatment of the Funds or their
shareholders. In addition, state and local tax consequences of an investment in
a Fund may differ from the federal income tax consequences described below.
Accordingly, shareholders are urged to consult their tax advisers regarding
specific questions as to federal, state, and local taxes.  Additional
information concerning taxes is set forth in the Statement of Additional
Information.
    
          For tax-deferred retirement accounts (such as Individual Retirement
Accounts or other retirement plans), dividend and capital gains distributions
from the Funds must be reinvested in additional shares. Only when you are over
59 1/2 years old can you receive distributions in cash. For regular investment
accounts, dividend and capital gains distributions may be reinvested in
additional shares or received in cash. See "General Information - Dividends." 
     
    
          IRAs or other tax-qualified retirement plans generally will not be
subject to federal tax liability on either dividend and capital gains
distributions from the Funds or redemption of shares of the Funds. Rather,
participants in such plans will be taxed when they begin taking distributions
from the plans. You should consult with a tax professional on the specific rules
governing your own tax-deferred arrangement. There are varying restrictions
imposed by the Internal Revenue Service on eligibility, contributions and
withdrawals, depending on the type of tax-deferred account you have selected.
The rules governing tax-deferred retirement plans are complex, and failure to
comply with the IRS's rules and regulations governing your type of plan may
result in a substantial cost to you, including the loss of tax advantages and
the imposition of additional taxes and penalties by the IRS.      

Tax Status
of the Funds           Each Fund is treated as a separate entity for federal
                       income tax purposes, and is not combined with the Trust's
                       other Funds. Each Fund intends to continue to qualify for
                       the special tax treatment afforded regulated investment
                       companies ("RICs") under Subchapter M of the Code, so as
                       to be relieved of federal income tax on net investment
                       income and net capital gains (the excess of net long-term
                       capital gain over net short-term capital losses)
                       distributed to shareholders.

                                                                              30

[Symbol appears here]     

 DISTRIBUTIONS:  A Fund distributes income dividends and capital gains. Income
 dividends represent the earnings from the Fund's investments; capital gains
 distributions occur when the Fund's investments are sold for more than their
 original purchase price.
- --------------------------------------------------------------------------------

Tax Status
of Distributions       Each Fund will distribute substantially all of its net
                       investment income (including net short-term capital
                       gains) and net capital gain to shareholders. Dividends
                       from a Fund's net investment income will be taxable to
                       its shareholders as ordinary income, whether received in
                       cash or in additional shares, to the extent of the Fund's
                       earnings and profits. Dividends from a Fund's net
                       investment income will qualify for the dividends received
                       deduction for corporate shareholders to the extent such
                       dividends are derived from dividends paid by Underlying
                       Portfolios that qualify for such deduction. Distributions
                       of net capital gains are taxable to shareholders as long-
                       term capital gains regardless of how long the
                       shareholders have held shares or whether the
                       distributions are received in cash or in additional
                       shares. Each Fund will make annual reports to
                       shareholders of the federal income tax status of all
                       distributions. Each Fund intends to make sufficient
                       distributions to avoid liability for the federal excise
                       tax applicable to RICs. Dividends declared by a Fund in
                       October, November or December of any year and payable to
                       shareholders of record on a date in such a month will be
                       deemed to have been paid by the Fund and received by the
                       shareholders on December 31 of that year if paid by the
                       Fund at any time during the following January.

                              Investment income received by the Funds from
                       sources within foreign countries may be subject to
                       foreign income taxes withheld at the source. The Funds
                       will not be able to treat shareholders as having paid
                       their proportionate share of such taxes for foreign tax
                       credit purposes.

                              Each sale, exchange, or redemption of a Fund's
                       shares is a taxable transaction to the shareholder.
    
PURCHASE AND REDEMPTION OF SHARES       ________________________________________
    
The Funds have been designed primarily for tax-advantaged retirement and other
long-term investment and savings accounts.  Class A Shares of the Funds are sold
on a continuous basis and may be purchased directly from the Trust's

                       of fiduciary agency or custody accounts by placing orders

 WHAT IS AN INTERMEDIARY?:  Any entity, such as a bank, broker-dealer, other
 financial institution, association or organization which has entered into an
 arrangement with the Distributor to sell Class D Shares to its customers.      
- --------------------------------------------------------------------------------
    
                       Both Class A and Class D shares are offered to tax-
                       advantaged retirement accounts. If you are investing in a
                       Fund through an IRA, 401(k) or other retirement plan, you
                       should contract your plan sponsor for the services and
                       procedures which pertain to your account.      
    
                       State securities laws may require financial institutions
                       and Intermediaries purchasing shares for their customers
                       to register as dealers pursuant to state laws. To allow

                       Agent on the same day, financial institutions and
                       Intermediaries may impose earlier cut-off times for
                       receipt of purchase orders directed through them. Certain
                       financial institutions and Intermediaries may charge
                       separate customer account fees. Information concerning
                       shareholder services and any charges will be provided to
                       the customer by the Intermediary.      
    
                       The shares you purchase through an Intermediary may be
                       held "of record" by that Intermediary. If you want to
                       transfer the registration of shares beneficially owned by
                       you, but held "of record" by an Intermediary, you should
                       call the Intermediary to request this change.      
    
GENERAL INFORMATION 
Business Days          You may buy, sell or exchange shares on days on which the
                       New York Stock Exchange is open for business (a "Business
                       Day"). Shares of the Funds are offered only to residents
                       of states in which the shares are eligible for purchase. 
                            
    
                       Class D purchase, exchange and redemption requests
                       received in "good order" will be effective as of the
                       Business Day received by the Transfer Agent as long as
                       the Transfer Agent receives the order and, in the case of
                       a purchase request, payment before 4:00 p.m. Eastern
                       time. Otherwise the purchase will be effective when
                       payment is received.      
    
                       Class A investors who desire to purchase or redeem shares
                       for cash must place their orders with the Transfer Agent
                       prior to 4:00 p.m. Eastern time on any Business Day for
                       the order to be accepted on that Business Day. Generally,
                       cash investments must be transmitted or delivered in
                       federal funds to the wire agent on the next Business Day
                       following the day the order is placed.      
    
Net Asset Value        An order to buy shares will be executed at a per share
                       price equal to the net asset value next determined after
                       the receipt of the purchase order by the Transfer Agent.
                       No certificates representing shares will be issued.      

                       An order to sell shares will be executed at the net asset
                       value per share next determined after receipt and
                       effectiveness of a request for redemption in good order.
                       Net asset value per share is determined daily as of the
                       close of business of the New York Stock Exchange
                       (currently, 4:00 p.m. Eastern time) on any Business Day.
                       Payment to shareholders for shares redeemed will be made
                       within 7 days after receipt by the Transfer Agent of the
                       redemption order.
    
                       At various times, a Fund may be requested to redeem
                       shares for which it has not yet received good payment. In
                       such circumstances, redemption proceeds will be forwarded
                       upon collection of payment for the shares; collection of
                       payment may take 10 or more days. Each Fund intends to
                       pay cash for all shares redeemed, but under abnormal
                       conditions that make payment in cash unwise, payment may
                       be made wholly or partly in portfolio securities with a
                       market value equal to the redemption price. In such
                       cases, an investor may incur brokerage costs in
                       converting such securities to cash.      

    
How the Net Asset
Value is Determined    The net asset value per share of each Fund is determined
                       by dividing the total market value of such Fund's
                       investments and other assets, less any liabilities, by
                       the total number of outstanding shares of that      

                                                                              32

                       Fund. The assets of each Fund consist primarily of shares
                       of the Underlying Portfolios, which are valued at their
                       respective net asset values. The Underlying Portfolios
                       value their portfolio securities at the last quoted sales
                       price for such securities, or, if there is no such
                       reported sales price on the valuation date, at the most
                       recent quoted bid price. An Underlying Portfolio may also
                       use a pricing service to obtain the last sale price of
                       each equity or fixed income security held in its
                       portfolio. Unlisted securities for which market
                       quotations are readily available are valued at the most
                       recent quoted bid price. Net asset value per share is
                       determined daily as of the close of business of the New
                       York Stock Exchange (currently, 4:00 p.m. Eastern time)
                       on each Business Day. Purchases will be made in full and
                       fractional shares of a Fund calculated to three decimal
                       places. Although the methodology and procedures for
                       determining net asset value per share are identical for
                       both Classes of a Fund, the net asset value per share of
                       one Class may differ from that of another Class because
                       of the different distribution and shareholder servicing
                       fees charged to each Class.      
    
Minimum Investments    The Class A shares are not subject to a minimum initial
                       investment.      

                       The minimum initial investment in a Fund's Class D shares
                       is $1,000, however, the minimum investment may be waived
                       at the Distributor's discretion. All subsequent purchases
                       must be at least $100 ($25 for payroll deductions
                       authorized pursuant to pre-approved payroll deduction
                       plans).
    
                       With respect to both Class A and Class D shares, the
                       Trust reserves the right to reject a purchase order when
                       the Distributor determines that it is not in the best
                       interest of the Trust or its shareholders to accept such
                       order. In addition, because excessive trading (including
                       short-term "market timing" trading) can hurt a Fund's
                       performance, each Fund may refuse purchase orders from
                       any shareholder account if the accountholder has been
                       advised that previous purchase and redemption
                       transactions were considered excessive in number or
                       amount. Accounts under common control or ownership,
                       including those with the same taxpayer identification
                       number and those administered so as to redeem or purchase
                       shares based upon certain predetermined market
                       indicators, will be considered one account for this
                       purpose.      
    
Maintaining a
Minimum Account
Balance                Due to the relatively high cost of handling small       
                       investments, a Fund reserves the right to redeem, at net
                       asset value, the Class D Shares any shareholder if,     
                       because of redemptions of shares by or on behalf of the 
                       shareholder, the account of such shareholder in a Fund  
                       has a value of less than $1,000, the minimum initial    
                       purchase amount. According, an investor purchasing shares
                       of a Fund in only the minimum investment amount may be  
                       subject ot such involuntary redemption if he or she     
                       thereafter redeems any of these shares. Before a Fund   
                       exercises its right to redeem such shares and to send the
                       proceeds to the shareholder, the shareholder will be    
                       given notice that the value of the shares in his or her 
                       account is less than the minimum account and will allowed
                       60 days to make an additional investment in a Fund in an
                       amount that will increase the value of the account to at
                       least $1,000. See "Purchase and Redemption of Shares" in
                       the Statement of Additional Information for examples of 
                       when the right of redemption may be suspended.      
    
HOW TO PURCHASE SHARES
THROUGH THE TRANSFER AGENT 
Opening an Account     Account Application forms may be obtained by calling 1-
                       800-342-5734.      
    
By Mail                Class A Shares may not be purchased by mail.      
    
                       Class D Shares by mailing a completed application and a
                       check (or other negotiable bank instrument or money
                       order) payable to "Class D Shares (Fund Name)." If you
                       send a check that does not clear, the purchase will be
                       canceled and you could be liable for any losses or fees
                       incurred by the Funds.      
    
By Telephone           Class A Shares may be purchased by telephone. To buy
                       shares by telephone call toll free at 1-800-342-5734. 
                            
    
                       Class D Shares may not be purchased by telephone.      

                                                                              33

By Fed Wire            Both Class A and Class D Shares may be purchased by Fed
                       Wire. To buy shares by Fed Wire call toll free at 1-800-
                       342-5734.      
    
Automatic Investment
Plan ("AIP")           Class A Shares may not be purchased through an Automatic
                       Investment Plan.      
    
                       Class D Shares may be purchased systematically through
                       deductions from your checking or savings accounts,
                       provided these accounts are maintained through banks
                       which are part of the Automated Clearing House ("ACH")
                       system. You may purchase shares on a fixed schedule 
                       (semi-monthly or monthly) with amounts as low as $25, or
                       as high as $100,000. The AIP enables you to achieve
                       dollar-cost averaging with respect to investments in
                       Funds with fluctuating net asset values through regular
                       purchases of a fixed dollar amount of shares in the
                       Funds. Dollar-cost averaging brings discipline to your
                       investing. Dollar-cost averaging results in more shares
                       being purchased when a Fund's net asset value is
                       relatively low and fewer shares being purchased when a
                       Fund's net asset value is relatively high, thereby
                       helping to decrease the average price of your shares.
                       Through the AIP, shares are purchased by transferring
                       monies (minimum of $25 per transaction per Fund) from
                       your designated checking or savings account. Your
                       systematic investment in the Fund(s) designated by you
                       will be processed on a regular basis at your option
                       beginning on or about either the first or fifteenth day
                       of the month or quarter you select. Upon notice, the
                       amount you commit to the AIP may be changed or canceled
                       at any time. The AIP is subject to account minimum
                       initial purchase amounts and minimum maintained balance
                       requirements.      
    
HOW TO EXCHANGE SHARES
THROUGH THE TRANSFER AGENT

                       Exchange privileges apply only to Class D Shares of the
                       Funds. They are not available to Class A Shares.      

- --------------------------------------------------------------------------------
    
[Symbol appears here]     
    
 HOW DOES AN EXCHANGE TAKE PLACE?  When making an exchange, you authorize the
 sale of your shares of one or more Funds in order to purchase the shares of
 another Fund. In other words, you are executing a sell order and then a buy
 order. This sale of your shares is a taxable event which could result in a
 taxable gain or loss.      
- --------------------------------------------------------------------------------
    
When Can You
Exchange Shares?       Once good payment for your shares has been received and
                       accepted (i.e., an account has been established), you may
                       exchange some or all of your shares of a Fund for Class D
                       Shares of the other Funds. Exchanges are made at net
                       asset value.      

                       The Trust reserves the right to change the terms and
                       conditions of the exchange privilege discussed herein, or
                       to terminate the exchange privilege, upon 60 days'
                       notice.
    
Requesting an
Exchange of Shares     To request an exchange, you must provide proper
                       instructions in writing to the Transfer Agent. Telephone
                       exchanges will also be accepted if you previously elected
                       this option on your account application.      

                       In the case of shares held "of record" by an Intermediary
                       but beneficially owned by you, you should contact the
                       Intermediary who will contact the Transfer Agent and
                       effect the exchange on your behalf.

                       If an exchange request is for Class D Shares of a Fund
                       whose net asset value is calculated as of a time earlier
                       than 4:00 p.m. Eastern time, the exchange request will
                       not be effective until the next Business Day. Anyone who
                       wishes to make an exchange must have received a current
                       prospectus of the Fund into which the exchange is being
                       made before the exchange will be effected.
    
Exchange Privilege
Limitations            The Funds' exchange privileges are not intended to afford
                       shareholders a way to speculate on short-term movements
                       in the market. Accordingly, in order to prevent excessive
                       use of the exchange privilege that      

                                                                              34
<PAGE>
 
    
                       may potentially disrupt the management of the Funds and
                       increase transaction costs, the Trust reserves the right
                       to limit the amount of or reject any exchange, as deemed
                       necessary by SFM, at any time.      
    
HOW TO SELL SHARES
THROUGH THE TRANSFER AGENT
BY MAIL                Class A shares may not be sold by mail.      

                       To sell your Class D shares, a written request for
                       redemption in good order must be received by the Transfer
                       Agent. Valid written redemption requests will be
                       effective on receipt. All shareholders of record must
                       sign the redemption request.
    
                       For information about the proper form of redemption
                       request, call 1-800-342-5734. You may also have the
                       proceeds mailed to an address of record designated on the
                       Account Application or specified by written instruction
                       to the Transfer Agent.      
    
                       The Transfer Agent may require that the signatures on the
                       written request be guaranteed. You should be able to
                       obtain a signature guarantee from a bank, broker, dealer,

                       association, clearing agency or savings association.
                       Notaries public cannot guarantee signatures. The
                       signature guarantee requirement will be waived if all of
                       the following conditions apply: (1) the redemption is for
                       not more than $5,000 worth of shares, (2) the redemption
                       check is payable to the shareholder(s) of record, and (3)
                       the redemption check is mailed to the shareholder(s) at
                       the shareholder(s) address of record. The Trust and the
                       Transfer Agent reserve the right to amend these
                       requirements without notice.

 WHAT IS A SIGNATURE GUARANTEE?
 A signature guarantee verifies the authenticity of your signature and may be
 obtained from any of the following: banks, brokers, dealers, certain credit
 unions, securities exchange or association, clearing agency or savings

- --------------------------------------------------------------------------------
    
By Telephone or
By Wire                Both Class A and Class D Shares may be sold by telephone
                       if you previously elected that option on the Account
                       Application. You may have the proceeds mailed to the
                       address of record, wired or sent by ACH to a commercial
                       bank account previously designated on the Account
                       Application. Under most circumstances, payments will be
                       transmitted on the next Business Day following receipt of
                       a valid telephone request for redemption. Wire redemption
                       requests may be made by calling 1-800-342-5734. Class D
                       Shares are subject to a wire redemption charge (presently
                       $10.00) which will be subtracted from the amount of the
                       redemption.      
    
                       Neither the Trust nor the Transfer Agent will be
                       responsible for any loss, liability, cost or expense for
                       acting upon wire instructions or upon telephone
                       instructions that it reasonably believes to be genuine.
                       The Trust and the Trust's Transfer Agent will each employ
                       reasonable procedures to confirm that instructions
                       communicated by telephone are genuine, including
                       requiring a form of personal identification prior to
                       acting upon instructions received by telephone and
                       recording telephone instructions. If market conditions
                       are extraordinarily active, or other extraordinary
                       circumstances exist, and you experience difficulties
                       placing redemption orders by telephone, you may wish to
                       consider placing your order by other means.      
    
Systematic Withdrawal
Plan ("SWP")           Systematic Withdrawal Plans may not be established for
                       Class A accounts.      

                       You may establish a systematic withdrawal plan for a
                       Class D account with a $10,000 minimum balance. Under the
                       plan, redemptions can be automatically processed from
                       accounts (monthly, quarterly, semi-annually or annually)
                       by check or by ACH wire with a minimum redemption amount
                       of $50. Please note that if withdrawals exceed income
                       dividends, your invested principal in the account will be
                       depleted.

                                                                              35

                       Thus, depending upon the frequency and amounts of the
                       withdrawal payments and/or any fluctuations in the net
                       asset value per share, your original investment could be
                       exhausted entirely. To participate in the SWP, you must
                       have your dividends automatically reinvested. You may
                       change or cancel the SWP at any time, upon written notice
                       to the Transfer Agent.      
    
Additional
Considerations For
IRAs or Other
Retirement Accounts    You may withdraw any portion of the funds in your account
                       by redeeming shares at any time. For a regular investment
                       account in the Funds, you may initiate a request by
                       writing or by telephoning. For an IRA or other tax-
                       deferred account, you must make your redemption request
                       in writing. Your redemption proceeds are normally mailed
                       within two business days after the receipt of the request
                       in good order.      
    
                              If you invest in the Funds through an IRA or other
                       tax-deferred retirement plan, you should be aware that
                       any distributions personally received by you prior to age
                       59 1/2 are generally subject to a 10% penalty tax, as
                       well as ordinary income taxes. To avoid the 10% penalty,
                       you must generally roll over your distribution to another
                       IRA or qualified plan within 60 days. In contrast,
                       distributions paid directly to your plan will not be
                       subject to this penalty tax.     
GENERAL INFORMATION        _____________________________________________________

The Trust              The Trust was organized as a Massachusetts business trust
                       under a Declaration of Trust dated November 20, 1995. The
                       Declaration of Trust permits the Trust to offer separate
                       portfolios of shares and different classes of each
                       portfolio. Shareholders may purchase shares in each Fund
                       through two separate classes of shares: Class A Shares
                       and Class D Shares, which provide for variations in
                       distribution, shareholder servicing and transfer agent
                       costs, voting rights and dividends. Additional
                       information pertaining to the Trust may be obtained by
                       writing to SEI Financial Management Corporation, 680 East
                       Swedesford Road, Wayne, Pennsylvania 19087-1658, or by
                       calling 1-800-342-5734. All consideration received by the
                       Trust for shares of any Fund and all assets of such Fund
                       belong to that Fund and would be subject to liabilities
                       related thereto.

                              The Trust pays its expenses, including fees of its
                       service providers, audit and legal expenses, expenses of
                       preparing prospectuses, proxy solicitation materials and
                       reports to shareholders, costs of custodial services and
                       registering the shares under federal and state securities
                       laws, pricing, insurance expenses, including litigation
                       and other extraordinary expenses, brokerage costs,
                       interest charges, taxes and organization expenses.

Trustees of
the Trust              The management and affairs of the Trust are supervised by
                       the Trustees under the laws of the Commonwealth of
                       Massachusetts. The Trustees have approved contracts under
                       which, as described above, certain companies provide
                       essential management services to the Trust.
    
Voting Rights          Each share held entitles the shareholder of record to one
                       vote. Each portfolio of the Trust will vote separately on
                       matters relating solely to that portfolio. Each class
                       will vote separately on matters pertaining to its
                       distribution plan. Each Fund will vote its Underlying
                       Portfolio shares in proportion to the votes of all other
                       shareholders of each respective Underlying Portfolio. 
                            
    
                              As a Massachusetts business trust, the Trust is
                       not required to hold annual meetings of shareholders, but
                       approval will be sought for certain changes in the
                       operation of the Trust and for the election of Trustees
                       under certain circumstances. In addition, a Trustee may
                       be removed by the remaining Trustees or by shareholders
                       at a special meeting called upon written request of
                       shareholders owning at least 10% of the outstanding
                       shares of the Trust. In the event that such a meeting is
                       requested, the Trust will provide appropriate assistance
                       and information to the shareholders requesting the
                       meeting.      
    
Reporting              The Trust issues unaudited financial information semi-
                       annually and audited financial statements annually. The
                       Trust furnishes proxy statements and other reports to
                       shareholders of record.      

                                                                              36

Shareholder
Inquiries              Class A shareholder inquiries should be directed to SEI
                       Financial Management Corporation, 680 East Swedesford
                       Road, Wayne, Pennsylvania 19087-1658. Class D shareholder
                       inquiries should be directed to DST Systems, Inc., P.O.
                       Box 419240, Kansas City, Missouri 64141-6240.

Dividends              Substantially all of the net investment income (exclusive
                       of capital gains) of each Fund is periodically declared
                       and paid as a dividend. Capital gains, if any, are
                       distributed at least annually.

                              Shareholders automatically receive all income
                       dividends and capital gain distributions in additional
                       shares at the net asset value next determined following
                       the record date, unless the shareholder has elected to
                       take such payment in cash. Shareholders may change their
                       election by providing written notice to the Adviser at
                       least 15 days prior to the distribution.

                              Dividends and capital gains of each Fund are paid
                       on a per-share basis. The value of each share will be
                       reduced by the amount of any such payment. If shares are
                       purchased shortly before the record date for dividend or
                       capital gains distributions, a shareholder will pay the
                       full price for the shares and receive some portion of the
                       price back as a taxable dividend or distribution.

                              The dividends on Class D Shares will normally be
                       lower than on Class A Shares of a Fund because of the
                       additional distribution, shareholder servicing and
                       transfer agent expenses charged to Class D Shares.

DESCRIPTION
OF PERMITTED
INVESTMENTS
AND RISK FACTORS
OF THE UNDERLYING
PORTFOLIOS                 _____________________________________________________
    
The following is a brief description of the permitted investment practices for
the Underlying Portfolios, and the associated risk factors:      


American Depositary
Receipts ("ADRs"),
Continental Depositary
Receipts ("CDRs"),
European Depositary
Receipts ("EDRs")
and Global
Depositary Receipts
("GDRs")               ADRs are securities, typically issued by a U.S. financial
                       institution (a "depositary"), that evidence ownership
                       interests in a security or a pool of securities issued by
                       a foreign issuer and deposited with the depositary. ADRs
                       include American Depositary Shares and New York Shares.
                       EDRs, which are sometimes referred to as Continental
                       Depositary Receipts ("CDRs"), are securities, typically
                       issued by a non-U.S. financial institution, that evidence
                       ownership interests in a security or a pool of securities
                       issued by either a U.S. or foreign issuer. GDRs are
                       issued globally and evidence similar ownership.

Asset-Backed 
Securities             Asset-backed securities are securities secured by non-
                       mortgage assets such as company receivables, truck and
                       auto loans, leases and credit card receivables. Such
                       securities are generally issued as pass-through
                       certificates, which represent undivided fractional
                       ownership interests in the underlying pools of assets.
                       Such securities also may be debt obligations and are
                       generally issued as the debt of a special purpose entity,
                       such as a trust, organized solely for the purpose of
                       owning such assets and issuing such debt.      

Convertible
Securities             Convertible securities are corporate securities that are
                       exchangeable for a set number of another security at a
                       prestated price. Convertible securities typically have
                       characteristics similar to both fixed income and equity
                       securities. Because of the conversion feature, the market
                       value of a convertible security tends to move with the
                       market value of the underlying stock. The value of a
                       convertible security is also affected by prevailing
                       interest rates, the credit quality of the issuer, and any
                       call provisions.

Demand
Instruments            Demand instruments are instruments which may involve a
                       conditional or unconditional demand feature which permits
                       the holder to demand payment of the principal amount of
                       the instrument. They may include variable amount master
                       demand notes.
    
Derivatives            Derivatives are securities that derive their value from
                       other securities. The following are considered derivative
                       securities: options on futures, futures, options (e.g.,
                                                                         ----- 
                       puts and calls), swap agreements, mortgage-backed
                       securities and forward commitments, floating and variable
                       rate securities, convertible securities, "stripped" U.S.
                       Treasury securities (e.g., Receipts and STRIPs),
                                            ----- 
                       privately issued stripped securities (e.g., TGRs, TRs and
                                                             ----- 
                       CATS).      


Equity
Securities             Equity securities represent ownership interests in a
                       company or corporation and consist of common stock,
                       preferred stock, warrants and rights to subscribe to
                       common stock and in general, any security that is
                       convertible into or exchangeable for common stock.
                       Investments in common stocks are subject to market risks
                       which may cause their prices to fluctuate over time. The
                       value of convertible securities is also affected by
                       prevailing interest rates, the credit quality of the
                       issuer and any call provisions. Changes in the value of
                       fund securities will not necessarily affect cash income
                       derived from these securities but will affect a
                       Portfolio's net asset value.

Fixed Income
Securities             Fixed income securities are debt obligations issued by
                       corporations, municipalities and other borrowers. The
                       market value of fixed income investments will generally
                       change in response to interest rate changes and other
                       factors. During periods of falling interest rates, the
                       values of outstanding fixed income securities generally
                       rise. Conversely, during periods of rising interest
                       rates, the values of such securities generally decline.
    
                              The Portfolios may invest in securities rated in
                       the fourth highest category by an NRSRO; such securities,
                       while still investment grade, are considered to have
                       speculative characteristics. The SIMT High Yield Bond
                       Fund must invest at least 65%, and the SIT Emerging
                       Markets Equity Portfolio may invest, up to 5% of its net
                       assets in securities rated lower than investment grade.
                       Bonds rated below investment grade are often referred to
                       as "junk bonds." Such securities involve greater risk of
                       default or price declines than investment grade
                       securities due to changes in the issuer's
                       creditworthiness and the outlook for economic 
                       growth.      
   
     
Forward Foreign
Currency
Contracts              A forward contract involves an obligation to purchase or
                       sell a specific currency amount at a future date, agreed
                       upon by the parties, at a price set at the time of the
                       contract. A Portfolio may also enter into a contract to
                       sell, for a fixed amount of U.S. dollars or other
                       appropriate currency, the amount of foreign currency
                       approximating the value of some or all of the Portfolio's
                       securities denominated in such foreign currency.
   
    
Futures Contracts
and Options
on Futures
Contracts              Futures contracts provide for the future sale by one
                       party and purchase by another party of a specified amount
                       of a specific security at a specified future time and at
                       a specified price. An option on a futures contract gives
                       the purchaser the right, in exchange for a premium, to
                       assume a position in a futures contract at a specified
                       exercise price during the term of the option. A Portfolio
                       may use futures contracts and related options for bona
                       fide

                                                                              38

                       hedging purposes, to offset changes in the value of
                       securities held or expected to be acquired or be disposed
                       of, to minimize fluctuations in foreign currencies, or to
                       gain exposure to a particular market or instrument. A
                       Portfolio will minimize the risk that it will be unable
                       to close out a futures contract by only entering into
                       futures contracts which are traded on national futures
                       exchanges. In addition, a Portfolio will only sell
                       covered futures contracts and options on futures
                       contracts.

                              Stock and bond index futures are futures contracts
                       for various stock and bond indices that are traded on
                       registered securities exchanges. Stock and bond index
                       futures contracts obligate the seller to deliver (and the
                       purchaser to take) an amount of cash equal to a specific
                       dollar amount times the difference between the value of a
                       specific stock or bond index at the close of the last
                       trading day of the contract and the price at which the
                       agreement is made.

                              Stock and bond index futures contracts are
                       bilateral agreements pursuant to which two parties agree
                       to take or make delivery of an amount of cash equal to a
                       specified dollar amount times the difference between the
                       stock or bond index value at the close of trading of the
                       contract and the price at which the futures contract is
                       originally struck. No physical delivery of the stocks or
                       bonds comprising the Index is made; generally contracts
                       are closed out prior to the expiration date of the
                       contract.

                              No price is paid upon entering into futures
                       contracts. Instead, a Portfolio would be required to
                       deposit an amount of cash or U.S. Treasury securities
                       known as "initial margin." Subsequent payments, called
                       "variation margin," to and from the broker, would be made
                       on a daily basis as the value of the futures position
                       varies (a process known as "marking to market"). The
                       margin is in the nature of a performance bond or good-
                       faith deposit on a futures contract.
    
                              Eurodollar instruments are U.S. dollar-denominated
                       futures contracts or options thereon which are linked to
                       the London Interbank Offered Rate ("LIBOR"), although
                       foreign currency denominated instruments are available
                       from time to time. Eurodollar futures contracts enable
                       purchasers to obtain a fixed rate for the lending of the
                       funds and sellers to obtain a fixed rate for borrowings. 
                            

                              There are risks associated with these activities,
                       including the following: (1) the success of a hedging
                       strategy may depend on an ability to predict movements in
                       the prices of individual securities, fluctuations in
                       markets and movements in interest rates; (2) there may be
                       an imperfect or no correlation between the changes in
                       market value of the securities held by the Portfolio and
                       the prices of futures and options on futures; (3) there
                       may not be a liquid secondary market for a futures
                       contract or option; (4) trading restrictions or
                       limitations may be imposed by an exchange; and (5)
                       government regulations may restrict trading in futures
                       contracts and futures options.

                              A Portfolio may enter into futures contracts and
                       options on futures contracts traded on an exchange
                       regulated by the Commodities Futures Trading Commission
                       ("CFTC"), as long as, to the extent that such
                       transactions are not for "bona fide hedging purposes,"
                       the aggregate initial margin and premiums on such
                       positions (excluding the amount by which such options are
                       in the money) do not exceed 5% of a Portfolio's net
                       assets. A Portfolio may buy and sell futures contracts
                       and related options to manage its exposure to changing
                       interest rates and securities prices. Some strategies
                       reduce a Portfolio's exposure to price fluctuations,
                       while others tend to increase its market exposure.
                       Futures and options on futures can be volatile
                       instruments and involve certain risks that could
                       negatively impact a Portfolio's return.

                              In order to avoid leveraging and related risks,
                       when a Portfolio purchases futures contracts, it will
                       collateralize its position by depositing an amount of
                       cash or cash equivalents, equal to the market value of
                       the futures positions held, less margin deposits, in a
                       segregated account with the Trust's custodian. Collateral
                       equal to the current market value of the futures position
                       will be marked to market on a daily basis.
    
Illiquid
Securities             Illiquid securities are securities that cannot be
                       disposed of within seven business days at approximately
                       the price at which they are being carried on the
                       Portfolio's books. Illiquid securities include demand
                       instruments with a demand notice period exceeding seven
                       days, when there is no secondary market for such security
                       and repurchase agreements with durations over seven days
                       in length.      
    
Money Market
Instruments            Money market securities are high-quality, dollar-
                       denominated, short-term debt instruments. They consist
                       of: (i) bankers' acceptances, certificates of deposits,
                       notes and time deposits of highly-rated U.S. banks and
                       U.S. branches of foreign banks; (ii) U.S. Treasury
                       Obligations and instrumentalities of the U.S. Government;
                       (iii) high-quality commercial paper issued by U.S. and
                       foreign corporations; (iv) debt obligations with a
                       maturity of one year or less issued by corporations with
                       outstanding high-quality commercial papers; and (v)
                       repurchase agreements involving any of the foregoing
                       obligations entered into with highly-rated banks and
                       broker-dealers.      

                                                                              39

Mortgage-Backed
Securities
                       Mortgage-backed securities are instruments that entitle
                       the holder to a share of all interest and principal
                       payments from mortgages underlying the security. The
                       mortgages backing these securities include conventional
                       fifteen and thirty-year fixed rate mortgages, graduated
                       payment mortgages, adjustable rate mortgages, and balloon
                       mortgages. During periods of declining interest rates,
                       prepayment of mortgages underlying mortgage-backed
                       securities can be expected to accelerate. Prepayment of
                       mortgages which underlie securities purchased at a
                       premium often results in capital losses, while prepayment
                       of mortgages purchased at a discount often results in
                       capital gains.      
    
                              Government Pass-Through Securities.  These are
                              ----------------------------------
                       securities that are issued or guaranteed by a U.S.
                       Government agency representing an interest in a pool of
                       mortgage loans. The primary issuers or guarantors of
                       these mortgage-backed securities are GNMA, FNMA and
                       FHLMC. Government and private guarantees do not extend to
                       the securities' value, which is likely to vary inversely
                       with fluctuations in interest rates.      
    
                              Private Pass-Through Securities.  These are
                              -------------------------------
                       mortgage-backed securities issued by a non-governmental
                       entity, such as a trust or corporate entity. These
                       securities include collateralized mortgage obligations
                       ("CMOs") and real estate mortgage investment conduits
                       ("REMICs"). While they are generally structured with one
                       or more types of credit enhancement, private pass-through
                       securities typically lack a guarantee by an entity having
                       the credit status of a governmental agency or
                       instrumentality.      
    
                              Collateralized Mortgage Obligations ("CMOs").  CMs
                              --------------------------------------------
                       are debt obligations or multiclass pass-through
                       certificates issued by agencies or instrumentalities of
                       the U.S. Government or by private originators or
                       investors in mortgage loans. Principal payments on the
                       underlying mortgage assets may cause CMOs to be retired
                       substantially earlier then their stated maturities or
                       final distribution dates, resulting in a loss of all or
                       part of any premium paid.      
    
                              Parallel Pay Securities; PAC Bonds.  Parallel pay
                              ----------------------------------  
                       CMOs and REMICS are structured to provide payments of
                       principal on each payment date to more than one class.
                       These simultaneous payments are taken into account in
                       calculating the stated maturity date or final
                       distribution date of each class, which must be retired by
                       its stated maturity date or final distribution date, but
                       may be retired earlier. Planned Amortization Class CMOs
                       ("PAC Bonds") generally require payments of a specified
                       amount of principal on each payment date. PAC Bonds are
                       always parallel pay CMOs with the required principal
                       payment on such securities having the highest priority
                       after interest has been paid to all classes.      
    
                              REMICs.  A REMIC is a CMO that qualifies for
                              ------
                       special tax treatment under the Internal Revenue Code and
                       invests in certain mortgages principally secured by
                       interests in real property. Investors may purchase
                       beneficial interests in REMICs, which are known as
                       "regular" interests, or "residual" interests. Guaranteed
                       REMIC pass-through certificates ("REMIC Certificates")
                       issued by FNMA or FHLMC represent beneficial ownership
                       interests in a REMIC trust consisting principally of
                       mortgage loans or FNMA, FHLMC or GNMA-guaranteed mortgage
                       pass-through certificates.      
    
                              Stripped Mortgage-Backed Securities ("SMBs").  
                              -------------------------------------------- 
                       SMBs are usually structured with two classes that receive
                       specified proportions of the monthly interest and
                       principal payments from a pool of mortgage securities.
                       One class may receive all of the interest payments and is
                       thus termed an interest-only class ("IO"), while the
                       other class may receive all of the principal payments and
                       is thus termed the principal-only class ("PO"). The value
                       of IOs tends to increase as rates rise and decrease as
                       rates fall; the opposite is true of POs.      
    
                              Risk Factors.  Due to the possibility of
                              ------------
                       prepayments of the underlying mortgage instruments,
                       mortgage-backed securities generally do not have a known
                       maturity. In the absence of a known maturity, market
                       participants generally refer to an estimated average
                       life. An average life estimate is a function of an
                       assumption regarding anticipated prepayment patterns,
                       based upon current interest rates, current conditions in
                       the relevant housing markets and other factors. The
                       assumption is necessarily subjective, and thus different
                       market participants can produce different average life
                       estimates with regard to the same security. There can be
                       no assurance that estimated average life will be a
                       security's actual average life.      
    
Mortgage Dollar
Rolls                  Mortgage "dollar rolls" are transactions in which
                       mortgage-backed securities are sold for delivery in the
                       current month and the seller simultaneously contracts to
                       repurchase substantially similar securities on a
                       specified future date. Any difference between the sale
                       price and the purchase price is netted against the
                       interest income foregone on the securities sold to arrive
                       at an implied borrowing rate. Alternatively, the sale and
                       purchase transactions can be executed at the same price,
                       with the Portfolio being paid a fee as consideration for
                       entering into the commitment to purchase.      

                                                                              40

Municipal
Securities             Municipal securities consist of (i) debt obligations
                       issued by or on behalf of public authorities to obtain
                       funds to be used for various public facilities, for
                       refunding outstanding obligations, for general operating
                       expenses, and for lending such funds to other public
                       institutions and facilities, and (ii) certain private
                       activity and industrial development bonds issued by or on
                       behalf of public authorities to obtain funds to provide
                       for the construction, equipment, repair or improvement of
                       privately operated facilities.      
 
    
Obligations of
Supranational
Entities               Obligations of supranational entities are obligations of
                       entities established through the joint participation of
                       several governments and include the Asian Development
                       Bank, the Inter-American Development Bank, International
                       Bank for Reconstruction and Development (World Bank),
                       African Development Bank, European Economic Community,
                       European Investment Bank and the Nordic Investment Bank. 
                            
    
Options                A put option gives the purchaser of the option the right
                       to sell, and the writer of the option the obligation to
                       buy, the underlying security at any time during the
                       option period. A call option gives the purchaser of the
                       option the right to buy, and the writer of the option the
                       obligation to sell, the underlying security at any time
                       during the option period. The premium paid to the writer
                       is the consideration for undertaking the obligations
                       under the option contract. The initial purchase (sale) of
                       an option contract is an "opening transaction." In order
                       to close out an option position, a Portfolio may enter
                       into a "closing transaction," which is simply the sale
                       (purchase) of an option contract on the same security
                       with the same exercise price and expiration date as the
                       option contract originally opened. If a Portfolio is
                       unable to effect a closing purchase transaction with
                       respect to an option it has written, it will not be able
                       to sell the underlying security until the option expires
                       or the Portfolio delivers the security upon exercise. 
                            

                              A Portfolio may purchase put and call options to
                       protect against a decline in the market value of the
                       securities in its portfolio or to anticipate an increase
                       in the market value of securities that the Portfolio may
                       seek to purchase in the future. A Portfolio purchasing
                       put and call options pays a premium therefor. If price
                       movements in the underlying securities are such that
                       exercise of the options would not be profitable for the
                       Portfolio, loss of the premium paid may be offset by an
                       increase in the value of the Portfolio's securities or by
                       a decrease in the cost of acquisition of securities by
                       the Portfolio.
    
                              A Portfolio may write covered call options as a
                       means of increasing the yield on its fund and as a means
                       of providing limited protection against decreases in its
                       market value. When a fund sells an option, if the
                       underlying securities do not increase or decrease to a
                       price level that would make the exercise of the option
                       profitable to the holder thereof, the option generally
                       will expire without being exercised and the Portfolio
                       will realized as profit the premium received for such
                       option. When a call option written by a Portfolio is
                       exercised, the Portfolio will be required to sell the
                       underlying securities to the option holder at the strike
                       price, and will not participate in any increase in the
                       price of such securities above the strike price. When a
                       put option written by a Portfolio is exercised, the
                       Portfolio will be required to purchase the underlying
                       securities at the strike price, which may be in excess of
                       the market value of such securities.      
    
                              A Portfolio may purchase and write options on an
                       exchange or over-the-counter. Over-the-counter options
                       ("OTC options") differ from exchange-traded options in
                       several respects. They are transacted directly with
                       dealers and not with a clearing corporation, and
                       therefore entail the risk of non-performance by the
                       dealer. OTC options are available for a greater variety
                       of securities and for a wider range of expiration dates
                       and exercise prices than are available for exchange-
                       traded options. Because OTC options are not traded on an
                       exchange, pricing is done normally by reference to
                       information from a market maker. It is the position of
                       the SEC that OTC options are generally illiquid.      
    
                              A Portfolio may purchase and write put and call
                       options on foreign currencies (traded on U.S. and foreign
                       exchanges or over-the-counter markets) to manage its
                       exposure to exchange rates. Call options on foreign
                       currency written by a Portfolio will be "covered," which
                       means that the Portfolio will own an equal amount of the
                       underlying foreign currency. With respect to put options
                       on foreign currency written by a Portfolio, the Portfolio
                       will establish a segregated account with its Custodian
                       consisting of cash or liquid, high grade debt securities
                       in an amount equal to the amount the Portfolio would be
                       required to pay upon exercise of the put.      

                              A Portfolio may purchase and write put and call
                       options on indices and enter into related closing
                       transactions. Put and call options on indices are similar
                       to options on securities except that options on an index
                       give the holder the right to receive, upon exercise of
                       the option, an amount of cash if the closing level of the
                       underlying index is greater than (or less than, in the
                       case of puts) the exercise price of the option. This
                       amount

                                                                              41
<PAGE>
 
                       of cash is equal to the difference between the closing
                       price of the index and the exercise price of the option,
                       expressed in dollars multiplied by a specified number.
                       Thus, unlike options on individual securities, all
                       settlements are in cash, and gain or loss depends on
                       price movements in the particular market represented by
                       the index generally, rather than the price movements in
                       individual securities. A Portfolio may choose to
                       terminate an option position by entering into a closing
                       transaction. The ability of a Portfolio to enter into
                       closing transactions depends upon the existence of a
                       liquid secondary market for such transactions.
    
                              All options written on indices must be covered.
                       When a Portfolio writes an option on an index, it will
                       establish a segregated account containing cash or liquid,
                       high grade debt securities with its Custodian in an
                       amount at least equal to the market value of the option
                       and will maintain the account while the option is open or
                       will otherwise cover the transaction.      
    
                              Risk Factors: Risks associated with options
                              -------------
                       transactions include: (1) the success of a hedging
                       strategy may depend on an ability to predict movements in
                       the prices of individual securities, fluctuations in
                       markets and movements in interest rates; (2) there may be
                       an imperfect correlation between the movement in prices
                       of options and the securities underlying them; (3) there
                       may not be a liquid secondary market for options; and (4)
                       while a Portfolio will receive a premium when it writes
                       covered call options, it may not participate fully in a
                       rise in the market value of the underlying security. 
                            
    
Receipts               Receipts are sold as zero coupon securities, which means
                       that they are sold at a substantial discount and redeemed
                       at face value at their maturity date without interim cash
                       payments of interest or principal. This discount is
                       accreted over the life of the security, and such
                       accretion will constitute the income earned on the
                       security for both accounting and tax purposes. Because of
                       these features, such securities may be subject to greater
                       interest rate volatility than interest paying Permitted
                       Investments. See also "Taxes."      
    
REITs                  REITs are trusts that invest primarily in commercial real
                       estate or real estate-related loans. The value of
                       interests in REITs may be affected by the value of the
                       property owned or the quality of the mortgages held by
                       the trust.      
    
Repurchase
Agreements             Repurchase agreements are agreements by which a Portfolio
                       obtains a security and simultaneously commits to return
                       the security to the seller at an agreed upon price
                       (including principal and interest) on an agreed upon date
                       within a number of days from the date of purchase.
                       Repurchase agreements are considered loans under the 1940
                       Act.      
    
Securities
Lending                In order to generate additional income, a Portfolio may
                       lend securities which it owns pursuant to agreements
                       requiring that the loan be continuously secured by
                       collateral consisting of cash or securities of the U.S.
                       Government or its agencies equal to at least 100% of the
                       market value of the loaned securities. A Portfolio
                       continues to receive interest on the loaned securities
                       while simultaneously earning interest on the investment
                       of cash collateral. Collateral is marked to market daily.
                       There may be risks of delay in recovery of the securities
                       or even loss of rights in the collateral should the
                       borrower of the securities fail financially or become
                       insolvent.      


Securities of
Foreign Issuers        There are certain risks connected with investing in
                       foreign securities. These include risks of adverse
                       political and economic developments (including possible
                       governmental seizure or nationalization of assets), the
                       possible imposition of exchange controls or other
                       governmental restrictions, less uniformity in accounting
                       and reporting requirements, the possibility that there
                       will be less information on such securities and their
                       issuers available to the public, the difficulty of
                       obtaining or enforcing court judgments abroad,
                       restrictions on foreign investments in other
                       jurisdictions, difficulties in effecting repatriation of
                       capital invested abroad and difficulties in transaction
                       settlements and the effect of delay on shareholder
                       equity. Foreign securities may be subject to foreign
                       taxes, and may be less marketable than comparable U.S.
                       securities. The value of a Portfolio's investments
                       denominated in foreign currencies will depend on the
                       relative strengths of those currencies and the U.S.
                       dollars, and a Portfolio may be affected favorably or
                       unfavorably by changes in the exchange rates or exchange
                       control regulations between foreign currencies and the
                       U.S. dollar. Changes in foreign currency exchange rates
                       also may affect the value of dividends and interest
                       earned, gains and losses realized on the sale of
                       securities and net investment income and gains if any, to
                       be distributed to shareholders by a Portfolio.
                       Furthermore, emerging market countries may have less
                       stable political environments than more developed
                       countries. Also it may be more difficult to obtain a
                       judgment in a court outside the United States.

                                                                              42

Short Sales            A Portfolio may sell securities short against the box. A
                       short sale is "against the box" if at all times during
                       which the short position is open, the Portfolio owns at
                       least an equal amount of the securities or securities
                       convertible into, or exchangeable without further
                       consideration for, securities of the same issue as the
                       securities that are sold short.
    
Swaps, Caps,
Floors and
Collars                Interest rate swaps, mortgage swaps, currency swaps and
                       other types of swap agreements such as caps, floors and
                       collars are designed to permit the purchaser to preserve
                       a return or spread on a particular investment or portion
                       of its portfolio, and to protect against any increase in
                       the price of securities a Portfolio anticipates
                       purchasing at a later date.      
    
                              In a typical cap or floor agreement, one party
                       agrees to make payments only under specified
                       circumstances, usually in return for payment of a fee by
                       the other party. An interest rate collar combines
                       elements of buying a cap and selling a floor.      
    
                              Swaps, Caps, Floors and Collars are sophisticated
                       hedging instruments that typically involve a small
                       investment of cash relative to the magnitude of risk
                       assumed. As a result, these instruments can be highly
                       volatile and have a considerable impact on a Portfolio's
                       performance.      
    
U.S. Government
Agency
Obligations            Obligations issued or guaranteed by agencies of the U.S.
                       Government, including, among others, the Federal Farm
                       Credit Bank, the Federal Housing Administration and the
                       Small Business Administration, and obligations issued or
                       guaranteed by instrumentalities of the U.S. Government,
                       including, among others, the Federal Home Loan Mortgage
                       Corporation, the Federal Land Banks and the U.S. Postal
                       Service. Some of these securities are supported by the
                       full faith and credit of the U.S. Treasury (e.g.,
                                                                   ----- 
                       Government National Mortgage Association securities), and
                       others are supported by the right of the issuer to borrow
                       from the Treasury (e.g., Federal Farm Credit Bank
                                          ----- 
                       securities), while still others are supported only by the
                       credit of the instrumentality (e.g., Federal National
                                                      ----- 
                       Mortgage Association securities).      
    
U.S. Treasury
Obligations            U.S. Treasury obligations consist of bills, notes and
                       bonds issued by the U.S. Treasury, as well as separately
                       traded interest and principal component parts of such
                       obligations known as Separately Traded Registered
                       Interest and Principal Securities ("STRIPS") that are
                       transferable through the Federal book-entry system.
                       STRIPS are sold as zero coupon securities.      
    
U.S. Treasury
Receipts               U.S. Treasury receipts are interests in separately traded
                       interest and principal component parts of U.S. Treasury
                       obligations that are issued by banks or brokerage firms
                       and are created by depositing U.S. Treasury notes and
                       obligations into a special account at a custodian bank.
                       The custodian holds the interest and principal payments
                       for the benefit of the registered owners of the
                       certificates of receipts. The custodian arranges for the
                       issuance of the certificates or receipts evidencing
                       ownership and maintains the register.      
    
Variable and
Floating Rate
Instruments            Certain obligations may carry variable or floating rates
                       of interest, may involve conditional or unconditional
                       demand features. Such instruments bear interest at rates
                       which are not fixed, but which vary with changes in
                       specified market rates or indices. The interest rates on
                       these securities may be reset daily, weekly, quarterly or
                       some other reset period, and may have a floor or ceiling
                       on interest rate changes.      

Warrants               Warrants are instruments giving holders the right, but
                       not the obligation, to buy equity or fixed income
                       securities of a company at a given price during a
                       specified period.
                     
                                                                              43
<PAGE>
 
When-Issued
and Delayed
Delivery
Securities             When-issued or delayed delivery transactions involve the
                       purchase of an instrument with payment and delivery
                       taking place in the future. Delivery of and payment for
                       these securities may occur a month or more after the date
                       of the purchase commitment.
    
Yankee
Obligations            Yankee obligations ("Yankees") are U.S. dollar-
                       denominated instruments of foreign issuers who either
                       register with the Securities and Exchange Commission or
                       issue under Rule 144A of the Securities Exchange Act of
                       1933, as amended. These consist of debt securities
                       (including preferred or preference stock of non-
                       governmental issuers), certificates of deposit, fixed
                       time deposits and bankers' acceptances issued by foreign
                       banks, and debt obligations of foreign governments or
                       their subdivisions, agencies and instrumentalities,
                       international agencies and supranational entities.      
    
Zero Coupon, Pay-
In-Kind and
Deferred Payment
Securities             Zero coupon securities are securities that are sold at a
                       discount to par value and securities on which interest
                       payments are not made during the life of the security.
                       Upon maturity, the holder is entitled to receive the par
                       value of the security. While interest payments are not
                       made on such securities, holders of such securities are
                       deemed to have received "phantom income" annually.
                       Because a Portfolio will distribute its "phantom income"
                       to shareholders, to the extent that shareholders elect to
                       receive dividends in cash rather than reinvesting such
                       dividends in additional shares, a Portfolio will have
                       fewer assets with which to purchase income producing
                       securities. Zero coupon, pay-in-kind and deferred payment
                       securities may be subject to greater fluctuation in value
                       and lesser liquidity in the event of adverse market
                       conditions that comparably rated securities paying cash
                       interest at regular interest payment periods.

THE TRUST
    
SEI Asset Allocation (the "Trust") is an open-end management investment company
that currently consists of the following five separate investment portfolios
(each a "Fund" and, together, the "Funds"):  Diversified Conservative Income
Fund, Diversified Conservative Fund, Diversified Moderate Growth Fund,
Diversified Growth Fund, and Diversified U.S. Stock Fund.  The Funds invest in
shares of certain portfolios (the "Underlying Portfolios") of SEI Liquid Asset
Trust ("SLAT"), SEI Institutional Managed Trust ("SIMT") and SEI International
Trust ("SIT"), each of which is managed by SEI Financial Management Corporation
("SFM"),  the Trust's investment adviser and manager.  (Together, SLAT, SIMT and
SIT are "Underlying Trusts.")  The Funds may invest in the following Underlying
Portfolios:  SIMT Large Cap Growth Portfolio, SIMT Large Cap Value Portfolio,
SIMT Small Cap Growth Portfolio, SIMT Small Cap Value Portfolio, SIT
International Equity Portfolio, SIT Emerging Markets Equity Portfolio, SIMT Core
Fixed Income Portfolio, SIMT High Yield Bond Portfolio, SIT International Fixed
Income Portfolio and SLAT Prime Obligation Portfolio.      
    
The Trust was established as a Massachusetts business trust pursuant to a
Declaration of Trust dated November 20, 1995.  The Declaration of Trust permits
the Trust to offer separate series ("portfolios") of units of beneficial
interest ("shares") and separate classes of portfolios.  Except for differences
between the Class A shares and Class D shares pertaining to sales charges,
distribution, voting rights, dividends and transfer agent expenses, each share
of each portfolio represents an equal proportionate interest in that Fund with
each other share of that Portfolio.      
    
This Statement of Additional Information relates to the following Funds:
Diversified Conservative Income Fund, Diversified Conservative Fund, Diversified
Moderate Growth Fund, Diversified Growth Fund and Diversified U.S. Stock Fund.
Shareholders may purchase shares in the Funds through two separate classes,
Class A and Class D, which provide for variations in distribution costs,
transfer agent fees, voting rights and dividends.      

DESCRIPTION OF PERMITTED INVESTMENTS OF THE UNDERLYING PORTFOLIOS
    
AMERICAN DEPOSITORY RECEIPTS ("ADRS")   Generally, ADRs are designed for trading
in the U.S. securities market, EDRs are designed for trading in European
securities markets and GDRs are designed for trading in non-U.S. securities
markets. ADRs, EDRs, CDRs and GDRs may be available for investment through
"sponsored" or "unsponsored" facilities. A sponsored facility is established
jointly by the issuer of the security underlying the receipt and a depositary,
whereas an unsponsored facility may be established by a depositary without
participation by the issuer of the receipt's underlying security. Holders of an
unsponsored depositary receipt generally bear all the costs of the unsponsored
facility. The depositary of an unsponsored facility frequently is under no
obligation to distribute shareholder communications received from the issuer of
the deposited security or to pass through to the holders of the receipts voting
rights with respect to the deposited securities.      
    
ASSET-BACKED SECURITIES   Asset-backed securities are securities backed by
automobile, credit-card or other types of receivables and in securities backed
by other types of assets.  Credit support for asset-backed securities may be
based on the underlying assets and/or provided by a third party through credit
enhancements.  Credit enhancement techniques include letters of credit,
insurance bonds, limited guarantees (which are generally provided by the
issuer), senior-subordinated structures and over-collateralization.      
<PAGE>
     
Asset-backed securities are not issued or guaranteed by the United States
Government or its agencies or instrumentalities; however, the payment of
principal and interest on such obligations may be guaranteed up to certain
amounts for a certain period by a letter of credit issued by a financial
institution (such as a bank or insurance company) unaffiliated with the issuers
of such securities. The purchase of asset-backed securities raises risk
considerations peculiar to the financing of the instruments underlying such
securities. For example, there is a risk that another party could acquire an
interest in the obligations superior to that of the holders of the asset-backed
securities.  There also is the possibility that recoveries on repossessed
collateral may not, in some cases, be available to support payments on those
securities.  Asset-backed securities entail prepayment risk, which may vary
depending on the type of asset, but is generally less than the prepayment risk
associated with the mortgage-backed securities.  In addition, credit card
receivables are unsecured obligations of the card holders.      
    
BANK NOTES   Bank notes are notes used to represent debt obligations issued by
banks in large denominations.      
    
BANKERS' ACCEPTANCES   Bankers' acceptances are bills of exchange or time drafts
drawn on and accepted by a commercial bank. Bankers' acceptances are issued by
corporations to finance the shipment and storage of goods. Maturities are
generally six months or less.      
    
CERTIFICATES OF DEPOSIT   Certificates of deposit are interest-bearing
instruments with a specific maturity. They are issued by banks and savings and
loan institutions in exchange for the deposit of funds and normally can be
traded in the secondary market prior to maturity. Certificates of deposit with
penalties for early withdrawal will be considered illiquid.      
    
COMMERCIAL PAPER   Commercial paper is a term used to describe unsecured short-
term promissory notes issued by banks, municipalities, corporations and other
entities. Maturities on these issues vary, generally from a few to 270 days.
         
CONVERTIBLE SECURITIES   Convertible securities, such as rights, bonds, notes
and preferred stocks, which are convertible into or exchange for common stocks,
have characteristics similar to both fixed income and equity securities.
Because of the conversion feature, the market value of convertible securities
tends to move together with the market value of the underlying stock.  As a
result, an Underlying Portfolio's selection of convertible securities is based,
to a great extent, on the potential for capital appreciation that may exist in
the underlying stock.      
    
CORPORATE ZERO COUPON SECURITIES   Corporate zero coupon securities are:  (i)
notes or debentures which do not pay current interest and are issued at
substantial discounts from par value; or (ii) notes or debentures that pay no
current interest until a stated date one or more years into the future, after
which date the issuer is obligated to pay interest until maturity,usually at a
higher rate than if interest were payable from the date of issuance and may also
make interest payments in kind (e.g., with identical zero coupon securities). 
                                ----
Such corporate zero coupon securities, in addition to the risks identified
above, are subject to the risk of the issuer's failure to pay interest and repay
principal in accordance with the terms of the obligation.      
    
FIXED INCOME SECURITIES  Fixed income securities with longer maturities tend to
produce higher yields, the prices of longer maturity securities and are also
subject to greater market fluctuations as a result of changes in interest rates.
Changes by recognized agencies in the rating of any fixed income security and in
the ability of an issuer to make payments of interest and principal will also
affect the value of these investments. Changes in the value of portfolio
securities will not affect cash income derived from these securities but will
affect a Portfolio's net asset value.

FOREIGN SECURITIES   Foreign securities are securities issued by non-U.S.
issuers.  Certain of the Underlying Portfolios may invest in U.S. dollar
denominated obligations or securities of foreign issuers.  Permissible
investments may consist of obligations of foreign branches of U.S. banks and
foreign banks, including European Certificates of Deposit, European Time
Deposits, Canadian Time Deposits, Yankee Certificates of Deposit and investments
in Canadian Commercial Paper and Europaper.  These instruments may subject the
Underlying Portfolio to investment risks that differ in some respects from those
related to investments in obligations of U.S. domestic issuers.  Such risks
include future adverse political and economic developments, the possible
imposition of withholding taxes on interest or other income, possible seizure,
nationalization, or expropriation of foreign deposits, the possible
establishment of exchange controls or taxation at the source, greater
fluctuations in value due to changes in the exchange rates, or the adoption of
other foreign governmental restrictions which might adversely affect the payment
of principal and interest on such obligations.  Such investments may also entail
higher custodial fees and sales commissions than domestic investments.  Foreign
issuers of securities or obligations are often subject to different accounting
treatment and engage in business practices different from those respecting
domestic issuers of similar securities or obligations.  Foreign branches of U.S.
banks and foreign banks may be subject to less stringent reserve requirements
than those applicable to domestic branches of U.S. banks.
    
Some securities issued by foreign governments or their subdivisions, agencies or
instrumentalities may not be backed by the full faith and credit of the foreign
government.      
    
The yankee obligations selected for the Portfolios will adhere to the same
quality standards as those utilized for the selection of domestic debt
obligations.     
    
FORWARD FOREIGN CURRENCY CONTRACTS   Forward Foreign Currency Contracts are
contracts which involve an obligation to purchase or sell a specified currency
at a future date at a price set at the time of the contract.  Forward currency
contracts do not eliminate fluctuations in the values of portfolio securities
but rather allow an Underlying Portfolio to establish a rate of exchange for a
future point in time.  At the maturity of a forward contract, the Portfolio may
either sell a portfolio security and make delivery of the foreign currency, or
it may retain the security and terminate its contractual obligation to deliver
the foreign currency by purchasing an "offsetting" contract with the same
currency trader, obligating it to purchase, on the same maturity date, the same
amount of the foreign currency. The Portfolio may realize a gain or loss from
currency transactions.     

When entering into a contract for the purchase or sale of a security in a
foreign currency, an Underlying Portfolio may enter into a foreign forward
currency contract for the amount of the purchase or sale price to protect
against variations, between the date the security is purchased or sold and the
date on which payment is made or received, in the value of the foreign currency
relative to the United States dollar or other foreign currency.

Also, when the Underlying Portfolio's adviser or sub-adviser anticipates that a
particular foreign currency may decline substantially relative to the United
States dollar or other leading currencies, in order to reduce risk, an
Underlying Portfolio may enter into a forward contract to sell, for a fixed
amount, the amount of foreign currency approximating the value of its securities
denominated in such foreign currency.  With respect to any such forward foreign
currency contract, it will not generally be possible to match precisely the
amount covered by that contract and the value of the securities involved due to
changes in the values of such securities resulting from market movements between
the date the forward contract is entered into and the date it matures.  In
addition, while forward currency contracts may offer protection from losses
resulting from declines in value of a particular foreign currency, they also
limit potential gains which might result from increases in the value of such
currency.  An Underlying Portfolio will also incur costs in connection with
forward foreign currency contracts

                                      S-4
<PAGE>
 
and conversions of foreign currencies into United States dollars.  The
Underlying Portfolios may enter into forward foreign currency contracts.
    
ILLIQUID SECURITIES  The SIT Emerging Markets Equity Portfolio believes that
carefully selected investments in joint ventures, cooperatives, partnerships,
private placements, unlisted securities and other similar situations
(collectively, "special situations") could enhance the Portfolio's capital
appreciation potential. Investments in special situations may be illiquid, as
determined by the Portfolio's advisers based on criteria approved by the Board
of Trustees.  To the extent these investments are deemed illiquid, the
Portfolio's investment in them will be consistent with its 10% restriction on
investment in illiquid securities.     

LOWER RATED SECURITIES   Lower-rated securities are lower-rated bonds commonly
referred to as "junk bonds" or high-yield/high-risk securities.  These
securities are rated "Baa" or lower by Moody's Investors Service, Inc.
("Moody's") or "BBB" or lower by Standard & Poor's Corporation ("S&P").  The
SIMT High Yield Bond Portfolio may invest in securities rated as low as "C" by
Moody's or "D" by S&P.  These ratings indicate that the obligations are
speculative and may be in default.  In addition, the Portfolio may invest in
unrated securities of comparable quality subject to the restrictions stated in
the Portfolio's Prospectus.

     CERTAIN RISK FACTORS RELATING TO HIGH-YIELD, HIGH-RISK SECURITIES.  The
descriptions below are intended to supplement the discussion in the Portfolio's
Prospectus under "Risk Factors Relating to Investing in Lower Rated Securities."
    
     GROWTH OF HIGH-YIELD, HIGH-RISK BOND MARKET.  The widespread expansion of
government, consumer and corporate debt within the U.S. economy has made the
corporate sector more vulnerable to economic downturns or increased interest
rates.  Further, an economic downturn could severely disrupt the market for
lower rated bonds and adversely affect the value of outstanding bonds and the
ability of the issuers to repay principal and interest.  The market for lower-
rated securities may be less active, causing market price volatility and limited
liquidity in the secondary market.  This may limit the Portfolios' ability to
sell such securities at their market value. In addition, the market for these
securities may be adversely affected by legislative and regulatory developments.
Credit quality in the junk bond market can change suddenly and unexpectedly, and
even recently issued credit ratings may not fully reflect the actual risks
imposed by a particular security.     

     SENSITIVITY TO INTEREST RATE AND ECONOMIC CHANGES.  Lower rated bonds are
very sensitive to adverse economic changes and corporate developments.  During
an economic down turn or substantial period of rising interest rates, highly
leveraged issuers may experience financial stress that would adversely affect
their ability to service their principal and interest payment obligations, to
meet projected business goals, and to obtain additional financing.  If the
issuer of a bond defaulted on its obligations to pay interest or principal or
entered into bankruptcy proceedings, the Portfolio may incur losses or expenses
in seeking recovery of amounts owed to it.  In addition, periods of economic
uncertainty and change can be expected to result in increased volatility of
market prices of high-yield, high-risk bonds and the Portfolio's net asset
value.

     PAYMENT EXPECTATIONS.  High-yield, high-risk bonds may contain redemption
or call provisions.  If an issuer exercised these provisions in a declining
interest rate market, the Portfolio would have to replace the security with a
lower yielding security, resulting in a decreased return for investors.
Conversely, a high-yield, high-risk bond's value will decrease in a rising
interest rate market, as will the value of the Portfolio's assets.  If the
Portfolio experiences significant unexpected net redemptions, this may force it
to sell high-yield, high-risk bonds without regard to their investment merits,
thereby decreasing the asset base upon which expenses can be spread and possibly
reducing the Portfolio's rate of return.

                                      S-5

     LIQUIDITY AND VALUATION.  There may be little trading in the secondary
market for particular bonds, which may affect adversely the Portfolio's ability
to value accurately or dispose of such bonds.  Adverse publicity and investor
perception, whether or not based on fundamental analysis, may decrease the
values and liquidity of high-yield, high-risk bonds, especially in a thin
market.

     LEGISLATION.  Federal laws require the divestiture by federally insured
savings and loan associations of their investments in lower rated bonds and
limit the deductibility of interest by certain corporate issuers of high yield
bonds.  These laws could adversely affect the Portfolio's net asset value and
investment practices, the secondary market for high-yield securities, the
financial condition of issuers of these securities and the value of outstanding
high-yield securities.
    
     TAXES.  The Portfolio may purchase debt securities (such as zero-coupon or
pay-in-kind securities) that contain original issue discount.  Original issue
discount that accrues in a taxable year is treated as earned by a Portfolio and
therefore is subject to the distribution requirements of the tax code even
though the Portfolio has not received any interest payments on such obligations
during that period.  Because the original issue discount earned by the Portfolio
in a taxable year may not be represented by cash income, the Portfolio may have
to dispose of other securities and use the proceeds to make distributions to
shareholders.     
    
MORTGAGE-BACKED SECURITIES   Mortgage-backed securities are securities which
represent pools of mortgage loans assembled for sale to investors by various
governmental agencies such as the Government National Mortgage Association
("GNMA") and government-related organizations such as the Federal National
Mortgage Association ("FNMA") and the Federal Home Loan Mortgage Corporation
("FHLMC"), as well as by non-governmental issuers such as commercial banks,
savings and loan institutions, mortgage bankers, and private mortgage insurance
companies.  Certain Underlying Portfolios may, consistent with their respective
investment objectives and policies, invest in mortgage-backed securities issued
or guaranteed by the U.S. Government or its agencies or instrumentalities.  The
SIMT Core Fixed Income Portfolio will only purchase mortgage-backed securities
issued or guaranteed by either the U.S. Government, or its agencies or
instrumentalities.  Although certain mortgage-backed securities are guaranteed
by a third party or otherwise similarly secured, the market value of the
security, which may fluctuate, is not so secured.  If an Underlying Portfolio
purchases a mortgage-backed security at a premium, that portion may be lost if
there is a decline in the market value of the security whether resulting from
changes in interest rates or prepayments in the underlying mortgage collateral.
As with other interest-bearing securities, the prices of such securities are
inversely affected by changes in interest rates.  However, though the value of a
mortgage-backed security may decline when interest rates rise, the converse is
not necessarily true since in periods of declining interest rates the mortgages
underlying the securities are prone to prepayment.  Because of these
unpredictable prepayment characteristics, it is often not possible to predict
accurately the average life or realized yield of a particular issue.  For this
and other reasons, a mortgage-backed security's stated maturity may be shortened
by unscheduled prepayments on the underlying mortgages and, therefore, it is not
possible to predict accurately the security's investment return to an Underlying
Portfolio.  In addition, regular payments received in respect of mortgage-backed
securities include both interest and principal.  No assurance can be given as to
the return an Underlying Portfolio will receive when these amounts are
reinvested.     
    
An Underlying Portfolio may also invest in collateralized mortgage obligations
("CMOs") structured on pools of mortgage pass-through certificates or mortgage
loans.  In a CMO, series of bonds or certificates are usually issued in multiple
classes.  Principal and interest paid on the underlying mortgage assets may be
allocated among the several classes of a series of a CMO in a variety of ways.
Each class of a CMO, often referred to as a "tranche," is issued with a specific
fixed or floating coupon rate and has a stated maturity or final distribution
date.  CMOs will be purchased only if rated in the three highest rating
categories by a nationally recognized statistical rating organization such as
Moody's or S&P.  For purposes of determining the average maturity of a     

                                      S-6
<PAGE>
 
mortgage-backed security in its investment portfolio, the SIMT Core Fixed Income
Portfolio will utilize the expected average life of the security, as estimated
in good faith by the Portfolio's adviser and sub-advisers, and will not invest
in mortgage-backed securities with an expected average maturity of over seven
years.
    
Stripped mortgage-backed securities ("SMBs") are mortgage-backed securities
where the interest portion of the security has been stripped from the principal
portion of the security, and the two component parts are sold separately.  SMBs
are extremely sensitive to changes in interest rates because of the impact
thereon of prepayment of principal on the underlying mortgage securities.  The
market for SMBs is not as fully developed as other markets; SMBs, therefore, may
be illiquid.     
    
There are a number of important differences among the agencies and
instrumentalities of the U.S. Government that issue mortgage-backed securities
and among the securities that they issue.  Mortgage-backed securities issued by
the GNMA include GNMA Mortgage Pass-Through Certificates (also known as "Ginnie
Maes") that are guaranteed as to the timely payment of principal and interest by
GNMA and such guarantee is backed by the full faith and credit of the United
States.  GNMA is a wholly-owned U.S. Government corporation within the
Department of Housing and Urban Development.  GNMA certificates also are
supported by the authority of GNMA to borrow funds from the U.S. Treasury to
make payments under its guarantee.  Mortgage-backed securities issued by the
FNMA include FNMA Guaranteed Mortgage Pass-Through Certificates (also known as
"Fannie Maes") that are solely the obligations of the FNMA and are not backed by
or entitled to the full faith and credit of the United States.  The FNMA is a
government-sponsored organization owned entirely by private stockholders.
Fannie Maes are guaranteed as to timely payment of the principal and interest by
FNMA.  Mortgage-backed securities issued by the FHLMC include FHLMC Mortgage
Participation Certificates (also known as "Freddie Macs" or "PC's").  The FHLMC
is a corporate instrumentality of the United States, created pursuant to an Act
of Congress, which is owned entirely by Federal Home Loan Banks.  Freddie Macs
are not guaranteed by the United States or by any Federal Home Loan Banks and do
not constitute a debt or obligation of the United States or of any Federal Home
Loan Bank.  Freddie Macs entitle the holder to timely payment of interest, which
is guaranteed by the FHLMC.  The FHLMC guarantees either ultimate collection or
timely payment of all principal payments on the underlying mortgage loans.  When
the FHLMC does not guarantee timely payment of principal, FHLMC may remit the
amount due on account of its guarantee of ultimate payment of principal at any
time after default on an underlying mortgage, but in no event later than one
year after it becomes payable.  For FHLMC REMIC Certificates, FHLMC guarantees
the timely payment of interest, and also guarantees the payment of principal as
payments are required to be made on the underlying mortgage participation
certificates.  FNMA REMIC Certificates are issued and guaranteed as to timely
distribution of principal and interest by FNMA.     
    
MORTGAGE DOLLAR ROLLS  Mortgage dollar rolls may be renewed prior to cash
settlement and initially may involve only a firm commitment agreement by the
Portfolio to buy a security.  If the broker-dealer to whom the Portfolio sells
the security becomes insolvent, the Portfolio's right to repurchase the security
may be restricted.  Other risks involved in entering into mortgage dollar rolls
include the risk that the value of the security may change adversely over the
term of the mortgage dollar roll and that the security the Portfolio is required
to repurchase may be worth less than the security that the Portfolio originally
held.     
    
To avoid any leveraging concerns, a Portfolio will place U.S. Government or
other liquid, high grade debt securities in a segregated account with its
Custodian in an amount sufficient to cover its repurchase obligation.     
    
MUNICIPAL LEASES  Municipal leases are instruments, or participations in
instruments, issued in connection with lease obligations or installment purchase
contract obligations of municipalities ("municipal lease obligations").
Although municipal lease obligations do not constitute general obligations of
the issuing municipality, a lease obligation is ordinarily backed by the
municipality's covenant to budget for, appropriate     

                                      S-7
<PAGE>
 
    
funds for, and make the payments due under the lease obligation.  However,
certain lease obligations contain "non-appropriation" clauses, which provide
that the municipality has no obligation to make lease or installment purchase
payments in future years unless money is appropriated for such purpose in the
relevant years.  Municipal lease obligations are a relatively new for of
financing, and the market for such obligations is still developing.  Municipal
leases will be treated as liquid only if they satisfy criteria set forth in
guidelines established by the Board of Trustees, and there can be no assurance
that a market will exist or continue to exist for any municipal lease
obligation.     
    
MUNICIPAL SECURITIES  Municipal Securities include general obligation bonds
backed by the taxing power of the issuing municipality, revenue bonds backed by
the revenues of a project or facility (tolls from a bridge, for example), and
certificates of participation, which represent an interest in an underlying
obligation or commitment, such as an obligation issued in connection with a
leasing arrangement.  The payment of principal and interest on private activity
and industrial development bonds generally is dependent solely on the ability of
a facility's user to meet its financial obligations and the pledge, if any, of
real and personal property as security for such payment.     
    
Municipal securities include both municipal notes and municipal bonds.
Municipal notes include general obligation notes, tax anticipation notes,
revenue anticipation notes, bond anticipation notes, certificates of
indebtedness, demand notes and construction loan notes and participation
interests in municipal notes.  Municipal bonds include general obligation bonds,
revenue or special obligation bonds, private activity and industrial development
bonds and participation interests in municipal bonds.     

OPTIONS  Options are contracts that give one of the parties to the contract the
right to buy or sell the security that is subject to the option at a stated
price during the option period, and obligates the other party to the contract to
buy or sell such security at the stated price during the option period.

The Underlying Portfolios may trade put and call options on stocks and stock
indices to a limited extent, as the Adviser or Sub-Adviser determines is
appropriate in seeking an Underlying Portfolio's investment objective, and
except as restricted by each Underlying Portfolio's investment limitations as
set forth below.  See "Investment Limitations."

         
    
A put option gives the purchaser (an Underlying Portfolio) the right to sell,
and imposes on the writer an obligation to buy, the underlying security at the
exercise price during the option period.  The advantage to an Underlying
Portfolio of buying the protective put is that if the price of the security
falls during the option period, the Underlying Portfolio may exercise the put
and receive the higher exercise price for the security.  However, if the
security rises in value, the Underlying Portfolio will have paid a premium for
the put, which will expire unexercised.     
    
A call option gives the purchaser the right to buy and imposes on the writer (an
Underlying Portfolio) the obligation to sell, the underlying security at the
exercise price during the option period.  The advantage to an Underlying
Portfolio of writing covered call options is that the Underlying Portfolio
receives a premium, which is additional income.  However, if the security rises
in value, an Underlying Portfolio may not fully participate in the market
appreciation.  During the option period, a covered call option writer may be
assigned an exercise notice by the broker-dealer through whom such call option
was sold requiring the writer to deliver the underlying security against payment
of the exercise price.  An Underlying Portfolio's obligation as the writer of a
covered call is terminated upon the expiration of the option period or at such
earlier time in which the writer effects a closing purchase transaction.  As
noted above, a closing purchase transaction is one in which an Underlying
Portfolio, when obligated as a writer of an option, terminates its obligation by
purchasing an option of the same     

                                      S-8
<PAGE>
 
series as the option previously written.  A closing purchase transaction cannot
be effected with respect to an option once the option writer has received an
exercise notice for such option.

The market value of an option generally reflects the market price of an
underlying security.  Other principal factors affecting market value include
supply and demand, interest rates, the pricing volatility of the underlying
security and the time remaining until the expiration date.
    
The Underlying Portfolios will engage in option transactions only as hedging
transactions and not for speculative purposes.     
    
PAY-IN-KIND BONDS  Pay-in-kind securities are securities which, at the issuer's
option, pay interest in either cash or additional securities for a specified
period.  Pay-in-kind bonds, like zero coupon bonds, are designed to give an
issuer flexibility in managing cash flow.  Pay-in-kind bonds are expected to
reflect the market value of the underlying debt plus an amount representing
accrued interest since the last payment.  Pay-in-kind bonds are usually less
volatile than zero coupon bonds, but more volatile than cash pay securities.
The SIMT High Yield Bond Portfolio may purchase in pay-in-kind bonds.     
    
PRIVATIZATIONS  Privatizations are foreign government programs for selling all
or part of the interests in government owned or controlled enterprises. The
ability of a U.S. entity to participate in privatizations in certain foreign
countries may be limited by local law, or the terms on which a Portfolio may be
permitted to participate may be less advantageous than those applicable for
local investors. There can be no assurance that foreign governments will
continue to sell their interests in companies currently owned or controlled by
them or that privatization programs will be successful.     

RECEIPTS  Receipts are interests in separately traded interest and principal
component parts of U.S. Government obligations that are issued by banks or
brokerage firms and are created by depositing U.S. Government obligations into a
special account at a custodian bank. The custodian holds the interest and
principal payments for the benefit of the registered owners of the certificates
or receipts. The custodian arranges for the issuance of the certificates or
receipts evidencing ownership and maintains the register. Receipts include
"Treasury Receipts" ("TRs"), "Treasury Investment Growth Receipts" ("TIGRs"),
and "Certificates of Accrual on Treasury Securities" ("CATS"). TIGRs and CATS
are interests in private proprietary accounts while TRs and STRIPS (See "U.S.
Treasury Obligations") are interests in accounts sponsored by the U.S. Treasury.
Receipts are sold as zero coupon securities; for more information, see "Zero
Coupon Securities."
    
REPURCHASE AGREEMENTS  Repurchase agreements are agreements under which
securities are acquired from a securities dealer or bank subject to resale on an
agreed upon date and at an agreed upon price which includes principal and
interest. The Portfolio or its agent will have actual or constructive possession
of the securities held as collateral for the repurchase agreement. An Underlying
Portfolio bears a risk of loss in the event the other party defaults on its
obligations and the Portfolio is delayed or prevented from exercising its right
to dispose of the collateral securities, or if the Portfolio realizes a loss on
the sale of the collateral securities. An adviser will enter into repurchase
agreements on behalf of a Portfolio only with financial institutions deemed to
present minimal risk of bankruptcy during the term of the agreement based on
guidelines established and periodically reviewed by the Trustees. An Underlying
Portfolio enters into repurchase agreements only with financial institutions
that it deems to present minimal risk of bankruptcy during the term of the
agreement, based on guidelines that are periodically reviewed by the Board of
Trustees. These guidelines currently permit each Portfolio to enter into
repurchase agreements only with approved banks and primary securities dealers,
as recognized by the Federal Reserve Bank of New York, which have minimum net
capital of $100 million, or with a member bank of the Federal Reserve System.
Repurchase agreements are considered to be loans collateralized by the
underlying security. Repurchase agreements entered into by an Underlying
Portfolio will provide that the     

                                      S-9
<PAGE>

underlying security at all times shall have a value at least equal to 102% of
the price stated in the agreement. This underlying security will be marked to
market daily.  The advisers and sub-advisers will monitor compliance with this
requirement.  Under all repurchase agreements entered into by an Underlying
Portfolio, the Custodian or its agent must take possession of the underlying
collateral.  However, if the seller defaults, an Underlying Portfolio could
realize a loss on the sale of the underlying security to the extent the proceeds
of the sale are less than the resale price.  In addition, even though the
Bankruptcy Code provides protection for most repurchase agreements, if the
seller should be involved in bankruptcy or insolvency proceedings, an Underlying
Portfolio may incur delay and costs in selling the security and may suffer a
loss of principal and interest if the Underlying Portfolio is treated as an
unsecured creditor.

RESTRICTED SECURITIES   Restricted securities are securities that may not be
sold freely to the public absent registration under the Securities Act of 1933,
as amended (the "1933 Act"), or an exemption from registration.  Section 4(2)
commercial paper is issued in reliance on an exemption from registration under
Section 4(2) of the 1933 Act, and is generally sold to institutional investors
(including investment companies) who purchase for investment.  Any resale of
such commercial paper must be in an exempt transaction, usually to an
institutional investor through the issuer or investment dealers who make a
market on such commercial paper.  Rule 144A securities are securities re-sold in
reliance on an exemption from registration provided by Rule 144A under the 1933
Act.
    
SECURITIES LENDING   Securities lending is an investment technique which enables
an Underlying Portfolio to generate additional income by lending its securities
pursuant to agreements requiring that the loans be continuously secured by cash,
securities of the U.S. Government or its agencies, or any combination of cash
and such securities, as collateral equal to at least the market value at all
times of the loaned securities.  Such loans will not be made if, as a result,
the aggregate amount of all outstanding loaned securities for an Underlying
Portfolio exceeds 20% of the value of that Portfolio's total assets taken at
fair market value.  Loans are made only to borrowers deemed by the adviser or
sub-adviser to be in good standing and when, in the judgment of the adviser or
sub-adviser, the consideration that can be earned currently from such loaned
securities justifies the attendant risk.  Any loan may be terminated by either
party upon reasonable notice to the other party.  Each of the Underlying
Portfolios may use the Distributor as a broker in these transactions.     
    
SWAP, CAPS, FLOORS AND COLLARS  In a typical interest rate swap, one party
agrees to make regular payments equal to a floating interest rate times a
"notional principal amount," in return for payments equal to a fixed rate times
the same amount, for a specific period of time. If a swap agreement provides for
payment in different currencies, the parties might agree to exchange the
notional principal amount as well. Swaps may also depend on other prices or
rates, such as the value of an index or mortgage prepayment rates.     
    
The buyer of an interest rate cap obtains the right to receive payments to the
extent that a specific interest rate exceeds an agreed-upon level, while the
seller of an interest rate floor is obligated to make payments to the extent
that a specified interest rate falls below an agreed-upon level.     
    
Swap agreements are subject to risks related to the counterparty's ability to
perform, and may decline in value if the counterparty's creditworthiness
deteriorates. A Portfolio may also suffer losses if it is unable to terminate
outstanding swap agreements or reduce its exposure through offsetting
transactions. Any obligation a Portfolio may have under these types of
arrangements will be covered by setting aside liquid high grade securities in a
segregated account. A Portfolio will enter into swaps only with counterparties
believed to be creditworthy.     
    
TIME DEPOSITS  Time deposits are non-negotiable receipts issued by a bank in
exchange for the deposit of funds. Like a certificate of deposit, it earns a
specified rate of interest over a definite period of time; however,     

                                      S-10
<PAGE>
 
    
it cannot be traded in the secondary market.  Time deposits with a withdrawal
penalty are considered to be illiquid securities.     
    
U.S. GOVERNMENT AGENCY SECURITIES  Guarantees of principal by agencies or
instrumentalities of the United Sates Government may be a guarantee of payment
at the maturity of the obligation so that in the event of a default prior to
maturity there might not be a market and thus no means of realizing on the
obligation prior to maturity. Guarantees as to the timely payment of principal
and interest do not extend to the value or yield of these securities nor to the
value of the Portfolio's shares.     
    
U.S. TREASURY RECEIPTS  U.S. Treasury receipts include "Treasury Receipts"
("TRs"), "Treasury Investment Growth Receipts" ("TIGRs") "Liquid Yield Option
Notes" ("LYONs") and "Certificates of Accrual on Treasury Securities" ("CATS").
LYONs, TIGRs and CATS are interests in private proprietary accounts, while TRs
and STRIPS are interests in accounts sponsored by the U.S. Treasury.     
    
VARIABLE OR FLOATING RATE INSTRUMENTS   Variable or floating rate instruments
are instruments which may involve a demand feature and may include variable
amount master demand notes available through the Custodian.  Variable or
floating rate instruments bear interest at a rate which varies with changes in
market rates.  The holder of an instrument with a demand feature may tender the
instrument back to the issuer at par prior to maturity.  A variable amount
master demand note is issued pursuant to a written agreement between the issuer
and the holder, its amount may be increased by the holder or decreased by the
holder or issuer, it is payable on demand, and the rate of interest varies based
upon an agreed formula.  There is a risk that the current interest rate on such
obligations may not accurately reflect existing market interest rates. A demand
instrument with a demand notice exceeding seven days may be considered illiquid
if there is no secondary market for such security.  The quality of the
underlying credit must, in the opinion of an Underlying Portfolio's advisers, be
equivalent to the long-term bond or commercial paper ratings applicable to
permitted investments for each Underlying Portfolio.  Each Underlying
Portfolio's advisers will monitor on an ongoing basis the earning power, cash
flow, and liquidity ratios of the issuers of such instruments and will similarly
monitor the ability of an issuer of a demand instrument to pay principal and
interest on demand.     

In case of obligations which include a put feature at the option of the debt
holder, the date of the put may be used as an effective maturity date for the
purpose of determining weighted average portfolio maturity.
    
WHEN-ISSUED SECURITIES  When-issued securities are securities for which delivery
and payment normally take place within 45 days after the date of commitment to
purchase. The SIMT Core Fixed Income and SIMT High Yield Bond Portfolios may
purchase securities that involve the purchase of debt obligations on a when-
issued basis, in which case delivery and payment normally take place within 45
days after the date of commitment to purchase. An Underlying Portfolio will only
make commitments to purchase obligations on a when-issued basis with the
intention of actually acquiring the securities, but may sell them before the
settlement date. The when-issued securities are subject to market fluctuation,
and no interest accrues to the purchaser during this period. The payment
obligation and the interest rate that will be received on the securities are
each fixed at the time the purchaser enters into the commitment. Purchasing
obligations on a when-issued basis is a form of leveraging and can involve a
risk that the yields available in the market when the delivery takes place may
actually be higher than those obtained in the transaction itself. In that case
there could be an unrealized loss at the time of delivery. An Underlying
Portfolio will establish a segregated account with the Custodian and maintain
liquid, high grade debt securities in an amount at least equal in value to that
Underlying Portfolio's commitments to purchase when-issued securities. If the
value of these assets declines, the Underlying Portfolio involved will place
additional liquid assets in the account on a daily basis so that the value of
the assets in the account is equal to the amount of such commitments.     

                                      S-11
<PAGE>
 
   
One form of when-issued or delayed-delivery security that a Portfolio may
purchase is a "to be announced" ("TBA") mortgage-backed security.  A TBA
mortgage-backed security transaction arises when a mortgage-backed security,
such as a GNMA pass-through security, is purchased or sold with specific pools
that will constitute that GNMA pass-through security to be announced on a future
settlement date.     

    
ZERO COUPON SECURITIES  Zero coupon securities are fixed income securities that
have been stripped of their unmatured interest coupons.  Zero coupon securities,
including STRIPS and Receipts (TRs, TIGRs and CATS) are sold at a (usually
substantial) discount and redeemed at face value at their maturity date without
interim cash payments of interest or principal.  The amount of this discount is
accredited over the life of the security, and the accretion constitutes the
income earned on the security for both accounting and tax purposes.  Because of
these features, the market prices of zero coupon securities are generally more
volatile than the market prices of securities that have similar maturity but
that pay interest periodically.  Zero coupon securities are likely to respond to
a greater degree to interest rate changes than are non-zero coupon securities
with similar maturity and credit qualities.  Shareholders may have to redeem
shares to pay tax on the "phantom income" earned by a Portfolio, and the
Portfolio may have to dispose of its portfolio securities under disadvantageous
circumstances to generate cash, or may have to leverage itself by borrowing cash
to satisfy distribution requirements.  A Portfolio accrues income with respect
to the securities prior to the receipt in cash payments.  Pay-in-kind securities
are securities that have interest payable by delivery of additional securities.
Deferred payment securities are securities that remain zero coupon securities
until a predetermined date, at which time the stated coupon rate becomes
effective and interest becomes payable at regular intervals.  See also "Taxes."
                                                                                

INVESTMENT LIMITATIONS OF THE FUNDS

FUNDAMENTAL POLICIES

Each Fund may not:

1.   Make loans if, as a result, more than 33 1/3% of its total assets would be
     loaned to other parties.
     
2.   Purchase or sell real estate, physical commodities, or commodities
     contracts, except that each Fund may purchase commodities contracts
     relating to financial instruments, such as financial futures or index
     contracts and options on such contracts.
     
3.   Issue senior securities (as defined in the 1940 Act) except as permitted by
     rule, regulation or order of the Securities and Exchange Commission (the

These investment limitations and certain of the investment limitations in each
Prospectus are fundamental policies of the Funds and may not be changed without
the approval of a majority of a Fund's outstanding shares.  The term "majority
of outstanding shares" means the vote of (i) 67% or more of a Fund's shares
present at a meeting, if more than 50% of the outstanding shares of a Fund are
present or represented by proxy, or (ii) more than 50% of a Fund's outstanding
shares, whichever is less.

     instrumentalities or shares of the Underlying Portfolios) of an issuer if,
     to the knowledge of the Trust, an officer, trustee, partner or director of
     the Trust or any investment adviser of the Trust owns beneficially more
     than 1/2 of the 1% of the shares or securities of such issuer and all such
     officers, trustees, partners and directors owning more than 1/2 of 1% of
     such shares or securities together own more than 5% of such shares or
     securities.
     
6.   Purchase securities of any company which has (with predecessors) a record
     of less than three years continuing operations if, as a result, more than
     5% of the total assets (taken at fair market value) would be invested in
     such securities.
     
7.   Purchase or hold illiquid securities, i.e., securities that cannot be
     disposed of for their approximate carrying value in seven days or less
     (which term includes repurchase agreements and time deposits maturing in
     more than seven days) if, in the aggregate, more than 15% of its net assets
     would be invested in illiquid securities.

    
     

A Fund's purchase of investment company securities results in the bearing of
expenses such that shareholders would indirectly bear a proportionate share of
the operating expenses of such investment companies, including advisory fees.

Each of the foregoing percentage limitations (except with respect to the
limitation on investing in illiquid securities) applies at the time of purchase.
These limitations are non-fundamental and may be changed by the Trust's Board of
Trustees without a vote of shareholders.

ADDITIONAL RESTRICTIONS

The following are non-fundamental investment limitations that are currently
required by one or more states in which the Trust sells shares of the Funds.
These limitations are in addition to, and in some cases more restrictive than,
the fundamental and non-fundamental investment limitations listed above.  A
limitation may be changed or eliminated without shareholder approval if the
relevant state changes or eliminates its policy

                                      S-13
<PAGE>
 
regarding such investment restriction.  As long as a Fund's shares are
registered for sale in such states, it may not:

1.   Invest more than 5% of its net assets in warrants; provided that, of this
     5%, no more than 2% will be in warrants that are not listed on the New York
     Stock Exchange or the American Stock Exchange.
     
2.   Invest more than 15% of its net assets in illiquid securities, including
     securities which are not readily marketable.
     
    
          

INVESTMENT LIMITATIONS OF THE UNDERLYING PORTFOLIOS
     
FUNDAMENTAL POLICIES
     
The following investment limitations are fundamental policies of each Underlying
Portfolio which cannot be changed with respect to an Underlying Portfolio wit
hout the consent of the holders of a majority of that Portfolio's outstanding
shares. The term "majority of outstanding shares" means the vote of (i) 67% or
more of an Underlying Portfolio's shares present at a meeting, if not more than
50% of the outstanding shares of an Underlying Portfolio are present or
represented by proxy, or (ii) more than 50% of an Underlying Portfolio's out
standing shares, whichever is less.
     
    
The SIMT Core Fixed Income, SIMT High Yield Bond, SIMT Large Cap Growth, SIMT
Large Cap Value, SIMT Small Cap Growth, SIMT Small Cap Value, SIT International
Equity and SIT Emerging Markets Equity Portfolios may not:     
     
1.   Borrow money in an amount exceeding 33 1/3% of the value of its total
     assets, provided that, for purposes of this limitation, investment
     strategies which either obligate a Portfolio to purchase securities or
     require a Portfolio to segregate assets are not considered to be
     borrowings. To the extent that its borrowings exceed 5% of its assets,
     (i) all borrowings will be repaid before making additional investments
     and any interest paid on such borrowings will reduce income; and (ii)
     asset coverage of at least 300% is required.
     
2.   Make loans if, as a result, more than 33 1/3% of its total assets would
     be lent to other parties, except that each Portfolio may (i) purchase or
     hold debt instruments in accordance with its investment objective and
     policies; (ii) enter into repurchase agreements; and (iii) lend its
     securities.
     
3.   Purchase or sell real estate, physical commodities, or commodities
     contracts, except that each Portfolio may purchase (i) marketable
     securities issued by companies which own or invest in real estate
     (including real estate investment trusts), commodities, or commodities
     contracts; and (ii) commodities contracts relating to financial
     instruments, such as financial futures contracts and options on such
     contracts.
     
4.   Issue senior securities (as defined in the 1940 Act) except as permitted
     by rule, regulation or order of the Securities and Exchange Commission
     (the "SEC").

     deemed an underwriter in selling a portfolio security.
     
6.   Invest in interests in oil, gas, or other mineral exploration or
     development programs and oil, gas or mineral leases.

The SIT International Fixed Income Portfolio may not:

<PAGE>
 
1.   Pledge, mortgage or hypothecate assets except to secure temporary

2.   Make loans, except that the Portfolio may (i) purchase or hold debt
     securities in accordance with its investment objectives and policies; (ii)
     engage in securities lending as described in this Prospectus and in the
     Statement of Additional Information; and (iii) enter into repurchase
     agreements, provided that repurchase agreements and time deposits maturing
     in more than seven days, and other illiquid securities, including
     securities which are not readily marketable or are restricted, are not to
     exceed, in the aggregate, 10% of the total assets of the International
     Fixed Income Portfolio.
     
3.   Invest in companies for the purpose of exercising control.
     
4.   Acquire more than 10% of the voting securities of any one issuer.

     which invest in real estate, commodities or commodities contracts.
     
6.   Make short sales of securities, maintain a short position or purchase
     securities on margin, except as described in the Prospectus and except that
     the Trust may obtain short-term credits as necessary for the clearance of
     security transactions.
     
7.   Act as an underwriter of securities of other issuers except as it may be
     deemed an underwriter in selling a portfolio security.
     
8.   Purchase securities of other investment companies except as permitted by
     the 1940 Act and the rules and regulations thereunder and may only
     purchase securities of money market funds.
     
9.   Issue senior securities (as defined in the 1940 Act) except in connection
     with permitted borrowing as described in the Prospectuses in this
     Statement of Additional Information or as permitted by rule, regulation
     or order of the SEC.
     
10.  Purchase or retain securities of an issuer if, to the knowledge of the
     Trust, an officer, trustee, partner or director of the Trust or any
     investment adviser of the Trust owns beneficially more than 1/2 of 1% of
     the shares or securities of such issuer and all such officers, trustees,
     partners and directors owning more than 1/2 of 1% of such shares or
     securities together own more than 5% of such shares or securities.
     
11.  Purchase securities of any company which has (with predecessors) a record
     of less than three years continuing operations if, as a result, more than
     5% of the total assets (taken at current value) would be invested in such
     securities.
     
12.  Invest in interests in oil, gas or other mineral exploration or development
     programs and oil, gas or mineral leases.
     
13.  Purchase restricted securities (securities which must be registered under
     the Securities Act of 1933, as amended (the "1933 Act"), before they may be
     offered or sold to the public) or other illiquid securities except as
     described in the Prospectuses and this Statement of Additional Information.

The SLAT Prime Obligation Portfolio may not:

                                      S-15

<PAGE>
 
1.   Borrow money except for temporary or emergency purposes and then only in an
     amount not exceeding 10% of the value of the total assets of the Portfolio.
     This borrowing provision is included solely to facilitate the orderly sale
     of portfolio securities to accommodate substantial redemption requests if
     they should occur and is not for investment purposes. All borrowings by the
     Portfolio will be repaid before making additional investments for the
     Portfolio and any interest on such borrowings will reduce the income of the
     Portfolio.
     
2.   Make loans, except that the Portfolio may purchase or hold debt instruments
     in accordance with its investment objective and policies and may enter into
     repurchase agreements, provided that repurchase agreements maturing in more
     than seven days, restricted securities and other illiquid securities are
     not to exceed, in the aggregate, 10% of the Portfolio's total assets.
     
3.   Pledge, mortgage or hypothecate assets except to secure temporary
     borrowings, as described in the Prospectus, in aggregate amounts not to
     exceed 10% of the net assets of such Portfolio taken at fair market value
     at the time such loan is incurred.
     
4.   Invest in companies for the purpose of exercising control.
     
5.   Acquire more than 10% of the voting securities of any one issuer.
     
6.   Purchase or sell real estate, real estate limited partnership interests,
     commodities or commodities contracts including futures contracts.
     However, subject to its permitted investments, the Portfolio may purchase
     obligations issued by companies which invest in real estate, real estate
     limited partnerships, commodities or commodities contracts.
     
7.   Make short sales of securities, maintain a short position or purchase
     securities on margin, except that the Portfolio may obtain short-term
     credits as necessary for the clearance of securities transactions.
     
8.   Act as an underwriter of securities of other issuers except as it may be
     deemed an underwriter in selling a portfolio security.
     
9.   Purchase securities of other investment companies except as permitted by
     the 1940 Act and the rules and regulations thereunder and, in any event,
     may not purchase securities of other open-end investment companies. Under
     these rules and regulations, the Portfolio is prohibited from acquiring
     the securities of other investment companies if, as a result of such
     acquisition, the Portfolio owns more than 3% of the total voting stock of
     an investment company; securities issued by any one investment company
     represent more than 5% of the total Portfolio assets; or securities
     (other than treasury stock) issued by all investment companies represent
     more than 10% of the total assets of the Portfolio. These investment
     companies typically incur fees that are separate from those fees incurred
     directly by the Portfolio. The Portfolio's purchase of such investment
     companies results in the layering of expenses such that shareholders
     would indirectly bear a proportionate share of such investment companies'
     expenses, including advisory fees.
     
10.  Issue senior securities (as defined in the Investment Company Act of
     1940) except in connection with permitted borrowings as described in the
     Prospectus and Statement of Additional Information or as permitted by
     rule, regulation or order of the Securities and Exchange Commission.
     
11.  Purchase or retain securities of an issuer if, to the knowledge of the
     Trust, an officer, trustee, partner or director of the Trust or any
     investment adviser of the Trust owns beneficially more than 1/2 of 1% of
     the shares or securities of such issuer and all such officers, trustees,
     partners and directors owning more than 1/2 of 1% of such shares or
     securities together own more than 5% of such shares of securities.

                                      S-16

<PAGE>
 
12.  Purchase securities of any company which has (with predecessors) a record
     of less than three years' continuing operations, except (i) obligations
     issued or guaranteed by the U.S. Government, its agencies or
     instrumentalities, or (ii) municipal securities which are rated by at least
     two nationally recognized municipal bond rating services, if, as a result,
     more than 5% of the total assets (taken at fair market value) of the
     Portfolio would be invested in such securities.
     
13.  Purchase warrants, puts, calls, straddles, spreads or combinations thereof.
     
14.  Invest in interests in oil, gas or other mineral exploration or development
     programs.
     
15.  Purchase restricted securities (securities which must be registered under
     the Securities Act of 1933 before they may be offered or sold to the
     public) or other illiquid securities except as described in the Prospectus
     and this Statement of Additional Information.

    
The foregoing percentages will apply at the time of the purchase of a security
and shall not be considered violated unless an excess or deficiency occurs
immediately after or as a result of a purchase of such security.  These
investment limitations and the investment limitations in each Underlying
Portfolio's Prospectus are fundamental policies of the Trust and may not be
changed without shareholder approval.     

NON-FUNDAMENTAL POLICIES

    
The SIMT Core Fixed Income, SIMT High Yield Bond, SIMT Large Cap Growth, SIMT
Large Cap Value, SIMT Small Cap Growth, SIMT Small Cap Value, SIT International
Equity and SIT Emerging Markets Equity Portfolios may not:     

1.   Pledge, mortgage or hypothecate assets except to secure borrowings
     permitted by the Portfolio's fundamental limitation on borrowing.
     
2.   Invest in companies for the purpose of exercising control.
     
3.   Purchase securities on margin or effect short sales, except that each
     Portfolio may (i) obtain short-term credits as necessary for the
     clearance of security transactions; (ii) provide initial and variation
     margin payments in connection with transactions involving futures
     contracts and options on such contracts; and (iii) make short sales
     "against the box" or in compliance with the SEC's position regarding the
     asset segregation requirements imposed by Section 18 of the 1940 Act.
     
4.   Invest its assets in securities of any investment company, except (i) by
     purchase in the open market involving only customary brokers' commissions;
     (ii) in connection with mergers, acquisitions of assets, or consolidations;
     or (iii) as otherwise permitted by the 1940 Act.
     
5.   Purchase or retain securities of an issuer if, to the knowledge of the
     Trust, an officer, trustee, partner or director of the Trust or any
     investment adviser of the Trust owns beneficially more than 1/2 of the 1%
     of the shares or securities of such issuer and all such officers, trustees,
     partners and directors owning more than 1/2 of 1% of such shares or
     securities together own more than 5% of such shares or securities.
     
6.   Purchase securities of any company which has (with predecessors) a record
     of less than three years continuing operations if, as a result, more than
     5% of the total assets (taken at fair market value) would be invested in
     such securities.

                                      S-17
<PAGE>
 
7.   Purchase or hold illiquid securities, i.e., securities that cannot be
     disposed of for their approximate carrying value in seven days or less
     (which term includes repurchase agreements and time deposits maturing in
     more than seven days) if, in the aggregate, more than 15% of its net assets
     would be invested in illiquid securities. Notwithstanding the foregoing,
     securities issued pursuant to Section 4(2) of the 1933 Act and securities
     eligible to be re-sold under Rule 144A of the 1933 Act may be treated as
     liquid securities under procedures adopted by the Board of Trustees.

8.   Purchase securities which must be registered under the 1933 Act, as
     amended, before they may be sold to the public, if, in the aggregate, more
     than 15% of its net assets would be invested in such restricted securities.
     Securities issued pursuant to Section 4(2) of the 1933 Act and securities
     exempted from registration upon re-sale by Rule 144A under the 1933 Act are
     not deemed to be restricted securities for purposes of this limitation.

The SLAT Prime Obligation Portfolio must:

1.   Maintain an average dollar-weighted portfolio maturity of 90 days or less.

Under rules and regulations, established by the SEC, an Underlying Portfolio is
prohibited from acquiring the securities of other investment companies if, as a
result of such acquisition, the Underlying Portfolio owns more than 3% of the
total voting stock of the company; securities issued by any one investment
company represent more than 5% of the Underlying Portfolio's total assets; or
securities (other than treasury stock) issued by all investment companies
represent more than 10% of the total assets of the Underlying Portfolio.  An
Underlying Portfolio's purchase of such investment company securities results in
the bearing of expenses such that shareholders would indirectly bear a
proportionate share of the operating expenses of such investment companies,
including advisory fees.

Each of the foregoing percentage limitations (except with respect to the
limitation on investing in illiquid securities) apply at the time of purchase.
These limitations are non-fundamental and may be changed by the Underlying
Trust's Board of Trustees without a vote of shareholders.

ADDITIONAL RESTRICTIONS

The following are non-fundamental investment limitations that are currently
required by one or more states in which the Trust sells shares of the Underlying
Portfolios.  These limitations are in addition to, and in some cases more
restrictive than, the fundamental and non-fundamental investment limitations
listed above.  A limitation may be changed or eliminated without shareholder
approval if the relevant state changes or eliminates its policy regarding such
investment restriction.  As long as an Underlying Portfolio's shares are
registered for sale in such states, it may not:

1.   Invest more than 5% of its net assets in warrants; provided that of this 5%
     no more than 2% will be in warrants that are not listed on the New York
     Stock Exchange or the American Stock Exchange.

2.   Invest in the securities of other investment companies except by purchase
     in the open market where no commission or profit to a sponsor or dealer
     results from the purchase other than the customary broker's commission, or
     except when the purchase is part of a plan of merger, consolidation,
     reorganization or acquisition.  [This restriction does not apply to the
     SIMT High Yield Bond Portfolio.]

    
3.   Invest more than 15% (10% with respect to the SIT Core International
     Equity, SIT Emerging Markets Equity, SIT International Fixed Income and
     SLAT Prime Obligation Portfolios) of its net assets in illiquid securities,
     including securities which are not readily marketable or are restricted.
                                                                                

                                      S-18
<PAGE>
 
4.   Invest more than 15% of its net assets in restricted securities.  For
     purposes of this limitation, securities exempted from registration under
     the 1933 Act, including Rule 144A securities and Section 4(2) commercial
     paper, are considered to be restricted securities.

5.   [SIT Portfolios only]  Make short sales, except short sales "against the
     box."


THE MANAGER AND SHAREHOLDER SERVICING AGENT TO THE FUNDS

The Administration Agreement provides that SEI Financial Management Corporation
("SFM") 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
Administration Agreement relates, except a loss resulting from willful
misfeasance, bad faith or gross negligence on the part of SFM in the performance
of its duties or from reckless disregard of its duties and obligations
thereunder.

The Administration Agreement shall remain effective for the initial term of the
Agreement and each renewal term thereof unless earlier terminated (a) by the
mutual written agreement of the parties; (b) by either party of the
Administration Agreement on 90 days' written notice, as of the end of the
initial term or the end of any renewal term; (c) by either party of the
Administration Agreement on such date as is specified in written notice given by
the terminating party, in the event of a material breach of the Administration
Agreement by the other party, provided the terminating party has notified the
other party of such breach at least 45 days prior to the specified date of
termination and the breaching party has not remedied such breach by the
specified date; (d) effective upon the liquidation of the Administrator; or (e)
as to any Fund or the Trust, effective upon the liquidation of such Fund or the
Trust, as the case may be.

    
SFM, a wholly-owned subsidiary of SEI, was organized as a Delaware corporation
in 1969, and has its principal business offices at 680 East Swedesford Road,
Wayne, Pennsylvania 19087-1658.  Alfred P. West, Jr., Henry H. Greer and Carmen
V. Romeo constitute the Board of Directors of SFM.  Mr. West serves as the
Chairman of the Board of Directors and Chief Executive Officer of SFM and SEI.
Mr. Greer serves as President and Chief Operating Officer of SFM and SEI.  SEI
and its subsidiaries are leading providers of funds evaluation services, trust
accounting systems, and brokerage and information services to financial
institutions, institutional investors and money managers.  SFM also serves as
administrator or manager to the following other mutual funds: SEI Liquid Asset
Trust; SEI Daily Income Trust, SEI Tax Exempt Trust, SEI Index Funds, SEI
International Trust, SEI Institutional Managed Trust, Stepstone Funds, The
Advisors' Inner Circle Fund, The Pillar Funds, CUFUND, STI Classic Funds,
CoreFunds, Inc., First American Funds, Inc., First American Investment Funds,
Inc., Rembrandt Funds(R), The Arbor Fund, 1784 Funds, The PBHG Fund, Inc.,
Bishop Street Funds, Conestoga Family of Funds, Insurance Investment Products
Trust, Marquis/sm/ Funds, Morgan Grenfell Investment Trust, Morgan Grenfell
Investment Trust, The Achievement Funds Trust, CrestFunds, STI Classic Variable
Trust, Inventor Funds, ARK Funds, and Monitor Funds.     

If operating expenses of any Fund exceed limitations established by certain
states, SFM will pay such excess.  SFM will not be required to bear expenses of
any Fund to an extent which would result in the Fund's inability to qualify as a
regulated investment company under provisions of the Internal Revenue Code. The
term "expenses" is defined in such laws or regulations, and generally excludes
brokerage commissions, distribution expenses, taxes, interest and extraordinary
expenses.


THE INVESTMENT ADVISER TO THE FUNDS

SFM will discharge its responsibilities subject to the supervision of, and
policies set by, the Trustees of the Trust.  The Trust's Advisory Agreement with
SFM provides that SFM Adviser shall not be protected against any liability

                                      S-19
<PAGE>
 
to the Trust or its shareholders by reason of willful misfeasance, bad faith or
gross negligence on its part in the performance of its duties or from reckless
disregard of its obligations or duties thereunder.

The Trust will operate in a manner that is distinctly different from virtually
all other investment companies. Most investment companies operate under a
structure in which a single related group of companies provide investment
advisory, administrative, and distribution services, and in which the investment
companies purchase equity and debt securities.  The Trust, however, invests in
shares of certain related investment companies that are advised and/or
administered by SFM (i.e., the Underlying Portfolios).  In turn, these
                     ----                                             
Underlying Portfolios invest in equity and debt securities.  SFM is responsible
for investing the assets of each Fund in certain of the Underlying Portfolios
within percentage ranges established by SFM, and for investing uninvested cash
balances in short-term investments, including repurchase agreements.

The continuance of the Advisory Agreement must be specifically approved at least
annually (i) by the vote of a majority of the outstanding shares of that Fund or
by the Trustees, and (ii) by the vote of a majority of the Trustees who are not
parties to such Agreement or "interested persons" of any party thereto, cast in
person at a meeting called for the purpose of voting on such approval.  The
Advisory Agreement will terminate automatically in the event of its assignment,
and is terminable at any time without penalty by the Trustees of the Trust or,
with respect to a Fund, by a majority of the outstanding shares of that Fund, on
not less than 30 days nor more than 60 days written notice to the SFM or by SFM
on 90 days written notice to the Trust.

    
SFM will reimburse each Fund for certain expenses which in any year exceed the
limits prescribed by any state in which the Fund's shares are qualified for
sale.  Presently, the most restrictive expense ratio limitation imposed by any
state is 2.5% of the first $30 million of a Fund's average daily net assets, 2%
of the next $70 million of such assets, and 1.5% of net assets in excess of $100
million.  For the purpose of determining whether a Fund is entitled to
reimbursement, the expenses of the Fund are calculated on a monthly basis.  If a
Fund is entitled to reimbursement, that month's management fee will be reduced
or postponed with any adjustment made after the end of the year.     

THE ADVISERS AND SUB-ADVISERS TO THE UNDERLYING PORTFOLIOS

    
Each Advisory and certain of the Sub-Advisory Agreements provide that each
Adviser (or Sub-Adviser) shall not be protected against any liability to the
Underlying Trusts or their shareholders by reason of willful misfeasance, bad
faith or gross negligence on its part in the performance of its duties or from
reckless disregard of its obligations or duties thereunder.  In addition,
certain of the Sub-Advisory Agreements provide that the Sub-Advisers shall not
be protected against any liability to the Underlying Trusts or their
Shareholders by reason of willful misfeasance, bad faith or negligence on its
part in the performance of its duties or from reckless disregard of its
obligations or duties thereunder.     

Pursuant to the Advisory and Sub-Advisory Agreements, the Underlying SIMT and
SIT Portfolios rely upon SFM for access, on a pooled investment basis, the core
elements of SFM's investment adviser selection, monitoring, and asset allocation
services.  Under the "Manager of Managers" approach employed by the Underlying
SIMT and SIT Portfolios, SFM will recommend and, if the Trustees of the
Underlying Trusts approve the recommendation, monitor for the Underlying
Portfolios one or more managers using a range of investment styles.

    
The continuance of each Advisory and Sub-Advisory Agreement must be specifically
approved at least annually (i) by the vote of a majority of the outstanding
shares of that Underlying Portfolio or by the Trustees, and (ii) by the vote of
a majority of the Trustees who are not parties to such Agreement or "interested
persons" of any party thereto, cast in person at a meeting called for the
purpose of voting on such approval.  Each Advisory or Sub-Advisory Agreement
will terminate automatically in the event of its assignment, and is terminable
at any time without penalty by the Trustees of the Trust or, with respect to an
Underlying Portfolio, by a majority of the outstanding shares of that Underlying
Portfolio, on not less than 30 days nor more than 60 days written     

                                      S-20
<PAGE>
 
    
notice to the Adviser (or Sub-Adviser) or by the Adviser (or Sub-Adviser) on 90
days written notice to the Trust.  However, SFM has obtained an exemptive order
from the Securities and Exchange Commission (the "SEC") that permits SFM, with
the approval of the Trust's Board of Trustees, to retain sub-advisers for an

DISTRIBUTION

The Trust has adopted a Distribution and Service Plan for Class D (the "Class D
Plan") in accordance with the provisions of Rule 12b-1 under the 1940 Act (which
regulates circumstances under which an investment company may directly or
indirectly bear expenses relating to the distribution of its shares).  In this
regard, the Board of Trustees has determined that the Class D Plan and the
Distribution Agreement are in the best interests of the shareholders.
Continuance of the Class D Plan must be approved annually by a majority of the
Trustees of the Trust and by a majority of the Trustees who are not "interested
persons" of the Trust (as that term is defined in the 1940 Act) and who have no
direct or indirect financial interest in the operation of a Distribution Plan or
in any agreements related thereto ("Qualified Trustees").  The Class D Plan
requires that quarterly written reports of amounts spent under the Plan and the
purposes of such expenditures be furnished to and reviewed by the Trustees.  The
Class D Plan may not be amended to increase materially the amount which may be
spent thereunder without approval by a majority of the outstanding shares of the
Fund or class affected.  All material amendments of the Class D Plan will
require approval by a majority of the Trustees of the Trust and of the Qualified
Trustees.

Except to the extent that SFM (as Manager and investment adviser) benefitted
through increased fees from an increase in the net assets of the Trust which may
have resulted in part from the expenditures, no interested person of the Trust
nor any Trustee of the Trust who is not an interested person of the Trust had a
direct or indirect financial interest in the operation of the Class D Plan or
related agreements.

Although banking laws and regulations prohibit banks from distributing shares of
open-end investment companies such as the Trust, according to an opinion issued
to the staff of the SEC by the Office of the Comptroller of the Currency,
financial institutions are not prohibited from acting in other capacities for
investment companies, such as providing shareholder services. Should future
legislative, judicial or administrative action prohibit or restrict the
activities of financial institutions in connection with providing shareholder
services, the Trust may be required to alter materially or discontinue its
arrangements with such financial institutions.

PERFORMANCE

From time to time, each Fund may advertise yield and/or total return. These
figures will be based on historical earnings and are not intended to indicate
future performance.

    
The yield of a Fund refers to the annualized income generated by an investment
in the Fund over a specified 30-day period. The yield is calculated by assuming
that the income generated by the investment during that period generated each
period over one year and is shown as a percentage of the investment. In
particular, yield will be calculated according to the following formula: Yield =
2[((a-b)/(cd)) + 1)/6/ - 1] where a = dividends and interest earned during the
period; b = expenses accrued for the period (net of reimbursement); c = the
current daily number of shares outstanding during the period that were entitled
to receive dividends; and d = the maximum offering price per share on the last
day of the period.     

    
The total return of a Fund refers to the average compounded rate of return to a
hypothetical investment for designated time periods (including but not limited
to, the period from which the Fund commenced operations through the specified
date), assuming that the entire investment is redeemed at the end of each
period.  In particular, total return will be calculated according to the
following formula: P(1+T)/n/ = ERV, where P = a hypothetical initial payment of
$1,000; T = average annual total return: n = number of years; and ERV = ending
redeemable value of a hypothetical $1,000 payment made at the beginning of the
designated time period as of the end of such period.     


PURCHASE AND REDEMPTION OF SHARES

The purchase and redemption price of shares is the net asset value of each
share.  The net asset value of each fund is determined by SFM and is based upon
the proportional net asset values of each Fund's Underlying Portfolio shares
(plus any available cash).  Each Underlying Portfolio's securities are valued by
SFM pursuant to valuations provided by an independent pricing service (generally
the last quoted sale price). Underlying Portfolio securities listed on a
securities exchange for which market quotations are available are valued at the
last quoted sale price on each Business Day (defined as days on which the New
York Stock Exchange is open for business ("Business Day")) or, if there is no
such reported sale, at the most recently quoted bid price. Unlisted securities
for which market quotations are readily available are valued at the most
recently quoted bid price. The pricing service may also use a matrix system to
determine valuations. This system considers such factors as security prices,
yields, maturities, call features, ratings and developments relating to specific
securities in arriving at valuations. The procedures of the pricing service and
its valuations are reviewed by the officers of the Trust under the general
supervision of the Trustees.

It is currently the Trust's policy to pay all redemptions in cash.  The Trust
retains the right, however, to alter this policy to provide for redemptions in
whole or in part by a distribution in kind of readily marketable securities held
by an Underlying Portfolio in lieu of cash.  Shareholders may incur brokerage
charges on the sale of any such securities so received in payment of
redemptions.  However, a shareholder will at all times be entitled to aggregate
cash redemptions from all Underlying Portfolios of the Trust during any 90-day
period of up to the lesser of $250,000 or 1% of the Trust's net assets.

A gain or loss for federal income tax purposes may be realized by a taxable
shareholder upon an in-kind redemption depending upon the shareholder's basis in
the shares of the Trust redeemed.

                                      S-26
<PAGE>
 
Purchases and redemptions of shares of the Funds may be made on any day the New
York Stock Exchange is open for business.  Currently, the following holidays are
observed by the Trust: New Year's Day, Presidents' Day, Good Friday, Memorial
Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day.

The Trust reserves the right to suspend the right of redemption and/or to
postpone the date of payment upon redemption for any period during which trading
on the New York Stock Exchange is restricted, or during the existence of an
emergency (as determined by the SEC by rule or regulation) as a result of which
disposal or evaluation of the portfolio securities is not reasonably
practicable, or for such other periods as the SEC may by order permit.  The
Trust also reserves the right to suspend sales of shares of the Portfolios for
any period during which the New York Stock Exchange, the Manager, the
Distributor, the  and/or the Custodian are not open for business.


SHAREHOLDER SERVICES

DISTRIBUTION INVESTMENT OPTION: Distributions of dividends and capital gains
made by the Funds may be automatically invested in shares of one of the Funds if
shares of the Fund are available for sale.  Such investments will be subject to
initial investment minimums, as well as additional purchase minimums.  A
shareholder considering the Distribution Investment Option should obtain and
read the prospectus of the Underlying Portfolios and consider the differences in
objectives and policies before making any investment.

REINSTATEMENT PRIVILEGE: A shareholder who has redeemed shares of any of the
Funds has a one-time right to reinvest the redemption proceeds in shares of the
Fund at their net asset value as of the time of reinvestment.  Such a
reinvestment must be made within 30 days of the redemption and is limited to the
amount of the redemption proceeds.  Although redemptions and repurchases of
shares are taxable events, a reinvestment within such 30-day period in the same
fund is considered a "wash sale" and results in the inability to recognize
currently all or a portion of a loss realized on the original redemption for
federal income tax purposes.  The investor must notify the Transfer Agent at the
time the trade is placed that the transaction is a reinvestment.

EXCHANGE PRIVILEGE: Some or all of the shares of a Fund's Class D Shares for
which payment has been received (i.e., an established account), may be exchanged
                                 ----                                           
for Class D Shares of other Funds of the Trust.  A shareholder may exchange the
shares of each Fund's Class D Shares, for which good payment has been received,
in his or her account at any time, regardless of how long he or she has held his
or her shares.  Exchanges are made at net asset value.  The Trust reserves the
right to change the terms and conditions of the exchange privilege discussed
herein, or to terminate the exchange privilege, upon sixty days' notice.
Exchanges will be made only after proper instructions in writing or by telephone
(an "Exchange Request") are received for an established account by the
Distributor.

Each Exchange Request must be in proper form (i.e., if in writing, signed by the
                                              ----                              
record owner(s) exactly as the shares are registered; if by telephone-proper
account identification is given by the dealer or shareholder of record), and
each exchange must involve either shares having an aggregate value of at least
$1,000 or all the shares in the account.  Each exchange involves the redemption
of the shares of a Fund (the "Old Fund") to be exchanged and the purchase at net
asset value of the shares of the other Funds (the "New Funds").  Any gain or
loss on the redemption of the shares exchanged is reportable on the
shareholder's federal income tax return, unless such shares were held in a tax-
deferred retirement plan or other tax-exempt account.  If the Exchange Request
is received by the Distributor in writing or by telephone on any business day
prior to the redemption cut-off time specified in the Prospectus, the exchange
usually will occur on that day if all the restrictions set forth above have been
complied with at that time.  However, payment of the redemption proceeds by the
Old Funds and thus the purchase of shares of the New Funds, may be delayed for
up to seven days if the Fund determines that such delay would be in the best
interest of all of its shareholders.  Investment dealers which have satisfied
criteria established by the Funds may also communicate a Shareholder's Exchange
Request to the Funds subject to the restrictions set forth above.  No more than
five exchange requests may be made in any one telephone Exchange Request.

TAXES

The following is only a summary of certain additional federal tax considerations
generally affecting the Funds and their shareholders that are not described in
the Funds' prospectus.  No attempt is made to present a detailed explanation of
the federal, state or local tax treatment of the Funds or their shareholders and
the discussion here and in the Funds' prospectus is not intended as a substitute
for careful tax planning.

This discussion of federal income tax consequences is based on the Internal
Revenue Code of 1986, as amended (the "Code"), and the regulations issued
thereunder, in effect on the date of this Statement of Additional Information.
New legislation, as well as administrative changes or court decisions, may
significantly change the conclusions expressed herein, and may have a
retroactive effect with respect to the transactions contemplated herein.

Each Fund is treated as a separate entity for federal income tax purposes and is
not combined with the Trust's other Funds.  Each Fund intends to qualify as a
regulated investment company ("RIC") under Subchapter M of the Code so that it
will be relieved of federal income tax on that part of its income that is
distributed to shareholders.  In order to qualify for treatment as a RIC, a Fund
must distribute annually to its shareholders at least 90% of its investment
company taxable income (generally, net investment income plus the excess, if
any, of net short-term capital gain over net long-term capital losses)
("Distribution Requirement") and also must meet several additional requirements.
Among these requirements are the following (i) at least 90% of a Fund's gross
income each taxable year must be derived from dividends, interest, payments with
respect to securities loans, and gains from the sale or other disposition of
stock or securities, or other income derived with respect to its business of
investing in such stock or securities; (ii) less than 30% of a Fund's gross
income each taxable year must be derived from the sale or other disposition of
stocks, securities or certain other investments held for less than three months;
(iii) at the close of each quarter of a Fund's taxable year, at least 50% of the
value of its total assets must be represented by cash and cash items, U.S.
government securities, securities of other RICs and other securities, with such
other securities limited, in respect of any one issuer, to an amount that does
not exceed 5% of the value of a Fund's assets and that does not represent more
than 10% of the outstanding voting securities of such issuer; and (iv) at the
close of each quarter of a Fund's taxable year, not more than 25% of the value
of its assets may be invested in securities (other than U.S. Government
securities or the securities of other RICs) of any one issuer or of two or more
issuers which are engaged in the same, similar, or related trades or businesses,
if the Fund owns at least 20% of the voting power of such issuers.

Notwithstanding the Distribution Requirement described above, which only
requires a Fund to distribute at least 90% of its annual investment company
taxable income and does not require any minimum distribution of net capital
gain, a Fund will be subject to a nondeductible 4% federal excise tax to the
extent it fails to distribute by the end of any calendar year at least 98% of
its ordinary income for that year and 98% of its capital gain net income (the
excess of short- and long-term capital gain over short- and long-term capital
loss) for the one-year period ending on October 31 of that year, plus certain
other amounts.  Each Fund intends to make sufficient distributions to avoid
liability for the federal excise tax.  A Fund may in certain circumstances be
required to liquidate portfolio investments in order to make sufficient
distributions to avoid federal excise tax liability when the investment advisor
might not otherwise have chosen to do so, and liquidation of investments in such
circumstances may affect the ability of a Fund to satisfy the requirements for
qualification as a RIC.

If capital gain distributions have been made with respect to shares that are
sold at a loss after being held for six months or less, then the loss is treated
as a long-term capital loss to the extent of the capital gain distributions.

If a Fund fails to qualify as a RIC for any year, all of its income will be
subject to tax at corporate rates, and its distributions (including capital gain
distributions) generally will be taxable as ordinary income dividends to its
shareholders, subject to the dividends received deduction for corporate
shareholders who have held shares for more than 45 days.

A Fund will be required in certain cases to withhold and remit to the United
States Treasury 31% of amounts payable to any shareholder who (1) has provided
the Fund either an incorrect tax identification number or no number at all, (2)
who is subject to backup withholding by the Internal Revenue Service for failure
to properly

                                      S-28

<PAGE>
 
report payments of interest or dividends, or (3) who has failed to certify to
the Fund that such shareholder is not subject to backup withholding.

STATE TAXES

A Fund is not liable for any income or franchise tax in Massachusetts if it
qualifies as a RIC for federal income tax purposes. Distributions by the Fund to
shareholders and the ownership of shares may be subject to state and local
taxes.  Shareholders should consult their own tax advisers regarding the effect
of federal, state and local taxes in their own individual circumstances.


PORTFOLIO TRANSACTIONS

The Trust has no obligation to deal with any dealer or group of dealers in the
execution of transactions in portfolio securities. Subject to policies
established by the Trustees, the advisers and sub-advisers are responsible for
placing orders to execute Fund transactions. In placing orders, it is the
Trust's policy to seek to obtain the best net results taking into account such
factors as price (including the applicable dealer spread), size, type and
difficulty of the transaction involved, the firm's general execution and
operational facilities, and the firm's risk in positioning the securities
involved. While the advisers generally seek reasonably competitive spreads or
commissions, the Trust will not necessarily be paying the lowest spread or
commission available. The Trust will not purchase portfolio securities from any
affiliated person acting as principal except in conformity with the regulations
of the SEC.

It is expected that the Funds may execute brokerage or other agency transactions
through the Distributor, a registered broker-dealer, for a commission, in
conformity with the 1940 Act, the Securities Exchange Act of 1934, as amended,
and rules and regulations of the SEC.  Under these provisions, the Distributor
is permitted to receive and retain compensation for effecting portfolio
transactions for a Fund on an exchange if a written contract is in effect
between the Distributor and the Trust expressly permitting the Distributor to
receive and retain such compensation.  These provisions further require that
commissions paid to the Distributor by the Trust for exchange transactions not
exceed "usual and customary" brokerage commissions. The rules define "usual and
customary" commissions to include amounts which are "reasonable and fair
compared to the commission, fee or other remuneration received or to be received
by other brokers in connection with comparable transactions involving similar
securities being purchased or sold on a securities exchange during a comparable
period of time." In addition, the Fund may direct commission business to one or
more designated broker-dealers, including the Distributor, in connection with
such broker-dealer's payment of certain of the Fund's expenses.  The Trustees,
including those who are not "interested persons" of the Trust, have adopted
procedures for evaluating the reasonableness of commissions paid to the
Distributor and will review these procedures periodically.

Since the Trust does not market its shares through intermediary brokers or
dealers, it is not the Trust's practice to allocate brokerage or principal
business on the basis of sales of its shares which may be made through such
firms. However, the Underlying Portfolio's advisers or sub-advisers may place
portfolio orders with qualified broker-dealers who recommend the Trust to
clients, and may, when a number of brokers and dealers can provide best price
and execution on a particular transaction, consider such recommendations by a
broker or dealer in selecting among broker-dealers.

The Trust does not expect to use one particular dealer, but the Underlying
Portfolio's advisers or sub-advisers may, consistent with the interests of the
Underlying Portfolios, select brokers on the basis of the research services they
provide to the Portfolio's advisers and sub-advisers.  Such services may include
analysis of the business or prospects of a company, industry or economic sector
or statistical and pricing services.  Information so received by the advisers or
sub-advisers will be in addition to and not in lieu of the services required to
be performed by an Underlying Portfolio's advisers or sub-advisers under the
advisory and sub-advisory agreements.  If in the judgment of an Underlying
Portfolio's advisers, the Underlying Portfolio, or other accounts managed by the
Underlying Portfolio's advisers or sub-advisers, will be benefitted by
supplemental research services, the Underlying Portfolio's advisers or sub-
advisers are authorized to pay brokerage commissions to a broker furnishing such
services that are in excess of commissions which another broker may have charged
for effecting the same transaction.  The expenses of an Underlying Portfolio's
advisers or sub-advisers will not necessarily be reduced as a result of the
receipt of such supplemental information.

DESCRIPTION OF SHARES

The Declaration of Trust authorizes the issuance of an unlimited number of
shares of each Fund, each of which represents an equal proportionate interest in
that Fund. Each share upon liquidation entitles a shareholder to a pro rata
share in the net assets of that Fund, after taking into account the additional
distribution second transfer agency expenses attributable to Class D Shares.
Shareholders have no preemptive rights. The Declaration of Trust provides that
the Trustees of the Trust may create additional series of shares or separate
classes of portfolios.  Share certificates representing the shares will not be
issued.


LIMITATION OF TRUSTEES' LIABILITY

The Declaration of Trust provides that a Trustee shall be liable only for his or
her own willful defaults and, if reasonable care has been exercised in the
selection of officers, agents, employees or administrators, shall not be liable
for any neglect or wrongdoing of any such person. The Declaration of Trust also
provides that the Trust will indemnify its Trustees and officers against
liabilities and expenses incurred in connection with actual or threatened
litigation in which they may be involved because of their offices with the Trust
unless it is determined in the manner provided in the Declaration of Trust that
they have not acted in good faith in the reasonable belief that their actions
were in the best interests of the Trust.  However, nothing in the Declaration of
Trust shall protect or indemnify a Trustee against any liability for his or her
willful misfeasance, bad faith, gross negligence or reckless disregard of his or
her duties.


VOTING

    
Where the Trust's Prospectus or Statement of Additional Information states that
an investment limitation or a fundamental policy may not be changed without
shareholder approval, such approval means the vote of (i) 67% or more of the
affected Fund's shares present at a meeting if the holders of more than 50% of
the outstanding shares of the Fund are present or represented by Proxy, or (ii)
more than 50% of the affected Fund's outstanding shares, whichever is less.     


SHAREHOLDER LIABILITY

The Trust is an entity of the type commonly known as a "Massachusetts business
trust."  Under Massachusetts law, shareholders of such a trust could, under
certain circumstances, be held personally liable as partners for the obligations
of the trust.  Even if, however, the Trust were held to be a partnership, the
possibility of the shareholders incurring financial loss for that reason appears
remote because the Trust's Declaration of Trust contains an express disclaimer
of shareholder liability for obligations of the Trust and requires that notice
of such disclaimer be given in each agreement, obligation or instrument entered
into or executed by or on behalf of the Trust or the Trustees, and because, the
Declaration of Trust provides for indemnification out of the Trust property for
any shareholders held personally liable for the obligations of the Trust.

SEI ASSET ALLOCATION TRUST

Notes to Financial Statements
February 16, 1996

1. Organization:

   
The Trust is organized as a Massachusetts Business Trust under a Declaration of
Trust dated November 20, 1995. The Trust is registered under the Investment
Company Act of 1940, as amended, as an open-end investment company with five
diversified Funds: Diversified Conservative Income Fund, Diversified
Conservative Fund, Diversified Moderate Growth Fund, Diversified Growth Fund,
and Diversified U.S. Stock Fund. Each Fund offers shareholders the opportunity
to invest in certain of the Underlying Portfolios, which are separately-managed
series of the following investment companies: SEI Institutional Managed Trust,
SEI International Trust, SEI Liquid Asset Trust. The Declaration of Trust
permits the Trust to offer separate classes of shares in each Fund, Class A
Shares and Class D Shares. The assets of each Fund are segregated, and a
shareholder's interest is limited to the Fund in which shares are held. The
Funds have not commenced operations except those related to organizational
matters and the sale of initial shares of beneficial interest to SEI Financial
Management Corporation (the "Adviser" and "Manager") on February 16, 1996. The
following is a summary of the significant accounting policies followed by the
Trust.

2. Investment Advisory, Management, Distribution and Shareholder Servicing
Agreements:    

The Trust expects to enter into the following service agreements:

Under the Investment  Advisory Agreement with the Trust, SEI Financial
Management Corporation ("SFM" or the "Adviser") will act as the investment
adviser to each Fund. For its investment advisory services to the Trust, the
Adviser will be entitled to a fee, which is calculated daily and paid monthly,
at an annual rate of .10% of each Fund's average daily net assets.

Under the Administration Agreement with the Trust, SFM will also provide the
Trust with overall management services, and act as dividend disbursing agent and
shareholder servicing agent. For these services to the Funds, SFM will be
entitled to a fee, which is calculated daily and paid monthly, at an annual rate
of .20% of the average daily net assets of each Fund.

SEI Financial Services company (the "Distributor"), a wholly-owned subsidiary of
SEI, will serve as each Fund's distributor pursuant to a distribution agreement
(the "Distribution Agreement") with the Trust. The Trustees of the Trust have
adopted a distribution and service plan for the Trust's Class D shares (the
"Class D Plan") pursuant to Rule 12b-1 under the 1940 Act. The Class D Plan
provides for payments to the distributor for distribution-related services at an
annual rate of .75% of each Fund's average daily net assets attributable to
Class D Shares. In addition, each Fund is authorized to pay the Distributor a
fee in connection with the ongoing servicing of shareholder accounts owning such
Class D Shares, calculated and payable monthly, at an annual rate of .25% of the
value of the average daily net assets attributable to Class D Shares of the
Fund. Periodically, the Distributor may waive a portion of the fees payable to
it under the Class D Plan in order to keep within certain sales charge limits
imposed by the Rules of the NASD. Specifically, any Fund's
distribution/shareholder servicing fees will be reduced in an amount equal to
the Fund's pro rata portion of any Underlying Portfolio in which the Fund
invests.

   
3. Organizational Costs, Offering Costs and Transactions with Affiliates:    

Organizational costs have been capitalized by the Fund and are being amortized
over 60 months commencing with operations. In the event any of the initial
shares are redeemed by any holder thereof during the period that the fund is
amortizing its organizational costs, the redemption proceeds payable to the
holder thereof by the Fund will be reduced by the unamortized organizational
costs in the same ratio as the number of initial shares being redeemed bears to
the number of initial shares outstanding at the time of the redemption. These
costs include legal fees of approximately $50,000 for organizational work
performed by a law firm of which an officer and Trustee of the Trust is a
Partner.
<PAGE>
 
Offering costs have been capitalized by the Fund and will be amortized over
twelve months commencing with operations.

Certain officers and/or trustees of the Trust are also officers of the Manager
and Adviser. The Trust pays each unaffiliated Trustee an annual fee for
attendance of quarterly, interim and committee meetings. Compensation of
officers and affiliated Trustees of the Trust is paid by the Manager.

                     DESCRIPTION OF CORPORATE BOND RATINGS      

                              
                          MOODY'S RATING DEFINITIONS      

    
LONG TERM BOND RATINGS      

    
Aaa Bonds which are rated Aaa are judged to be of the best quality.  They carry
the smallest degree of investment risk and are generally referred to as "gilt
edged."  Interest payments are protected by a large or by an exceptionally
stable margin and principal is secure.  While the various protective elements
are likely to change, such changes as can be visualized are most unlikely to
impair the fundamentally strong position of such issues.      

    
Aa Bonds which are rated 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 which make
the long-term risk appear somewhat larger than the Aaa securities.      

    
A Bonds which are rated A possess many favorable investment attributes and are
to be considered as upper-medium grade obligations.  Factors giving security to
principal and interest are considered adequate, but elements may be present
which suggest a susceptibility to impairment some time in the future.      

    
Baa Bonds which are rated Baa are considered as medium-grade obligations (i.e.,
they are neither highly protected nor poorly secured).  Interest payments and
principal security appear adequate for the present but certain protective
elements may be lacking or may be characteristically unreliable over any great
length of time.  Such bonds lack outstanding investment characteristics and in
fact have speculative characteristics as well.      

    
Ba Bonds which are rated Ba are judged to have speculative elements; their 
future cannot be considered as well-assured.  Often the protection of interest
and principal payments may be very moderate and thereby not well safeguarded
during both good and bad times over the future.  Uncertainty of position
characterizes bonds in this class.      

    
B Bonds which are rated B generally lack characteristics of the desirable
investment.  Assurance of interest and principal payments or of maintenance of
other terms of the contract over any long period of time may be small.      

    
Caa Bonds which are rated Caa are of poor standing.  Such issues may be in
default or there may be present elements of danger with respect to principal or
interest.      

    
Ca Bonds which are rated Ca represent obligations which are speculative in a
high degree.  Such issues are often in default or have other marked
shortcomings.      

    
C Bonds which are rated C are the lowest rated clas of bonds, and issues so 
rated can be regarded as having extremely poor prospects of ever attaining any
real investment standing.      

    
Moody's bond ratings, where specified, are applied to senior bank obligations
and insurance company senior policyholder and claims obligations with an
original maturity in excess of one year.  Obligations relying upon support
mechanisms such as letters-of-credit and bonds of indemnity are excluded unless
explicitly rated.      

    
Obligations of a branch of a bank are considered to be domiciled in the country
in which the branch is located.  Unless noted as an exception, Moody's rating on
a bank's ability to repay senior obligations extends only to branches located in
countries which carry a Moody's sovereign rating.  Such branch obligations are
rated at the      

                                      S-32
<PAGE>
 
    
lower of the bank's rating or Moody's sovereign rating for the bank deposits for
the country in which the branch is located.      

    
When the currency in which an obligation is denominated is not the same as the
currency of the country in which the obligation is domiciled, Moody's ratings do
not incorporate an opinion as to whether payment of the obligation will be
affected by the actions of the government controlling the currency of
denomination.  In addition, risk associated with bilateral conflicts between an
investor's home country and either the issuer's home country or the country
where an issuer branch is located are not incorporated into Moody's ratings. 
                                                                                

    
Moody's makes no representation that rated bank obligations or insurance company
obligations are exempt from registration under the U.S. Securities Act of 1933
or issued in conformity with any other applicable law or regulation.  Nor does
Moody's represent that any specific bank or insurance company obligation is
legally enforceable or is a valid senior obligation of a rated issuer.      

    
Moody's ratings are opinions, not recommendations to buy or sell, and their
accuracy is not guaranteed.  A rating should be weighed solely as one factor in
an investment decision and you should make your own study and evaluation of any
issuer whose securities or debt obligations you consider buying or selling.
                                                                                

    
Note: Moody's applies numerical modifiers, 1, 2 and 3 in each generic rating
classification from Aa through B in its corporate bond rating system.  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.      


                         
                     STANDARD & POOR'S RATING DEFINITIONS      

    
     A Standard & Poor's corporate or municipal debt rating is a current
assessment of the creditworthiness of an obligor with respect to a specific
obligation.  This assessment may take into consideration obligors such as
guarantors, insurers, or lessees.      

    
     The debt rating is not a recommendation to purchase, sell, or hold a
security, as it does not comment on market price or suitability for a particular
investor.      

    
     The ratings are based, in varying degrees, on the following considerations:
                                                                                

    
     (1)  Likelihood of default.  The rating assesses the obligor's capacity and
willingness as to timely payment of interest and repayment of principal in
accordance with the terms of the obligation.      

    
     (2)  The obligation's nature and provisions.      

    
     (3)  Protection afforded to, and relative position of, the obligation in
the event of bankruptcy, reorganization, or other arrangement under bankruptcy
laws and other laws affecting creditors' rights.      

    
     Likelihood of default is indicated by an issuer's senior debt rating.  If
senior debt is not rated, an implied senior debt rating is determined.
Subordinated debt usually is rated lower than senior debt to better reflect
relative position of the obligation in bankruptcy.  Unsecured debt, where
significant secured debt exists, is treated similarly to subordinated debt. 
                                                                                

    
LONG-TERM RATINGS DEFINITIONS      

    
INVESTMENT GRADE      
- ----------------

                                      S-33
<PAGE>
 
    
AAA  Debt rated 'AAA' has the highest rating assigned by S&P.  Capacity to pay
     interest and repay principal is extremely strong.      

    
AA   Debt rated 'AA' has a very strong capacity to pay interest and repay
     principal and differs from the highest rated debt only in small degree. 
                                                                                

    
A    Debt rated 'A' has a strong capacity to pay interest and repay principal,
     although it is somewhat more susceptible to adverse effects of changes in
     circumstances and economic conditions than debt in higher-rated categories.
                                                                                

    
BBB  Debt rated 'BBB' is regarded as having an adequate capacity to pay interest
     and repay principal.  Whereas it normally exhibits adequate protection
     parameters, adverse economic conditions or changing circumstances are more
     likely to lead to a weakened capacity to pay interest and repay principal
     for debt in this category than in higher rated categories.      

    
SPECULATIVE GRADE      
- -----------------

    
     Debt rated 'BB', 'B', 'CCC', 'CC', and 'C' is regarded as having
predominantly speculative characteristics with respect to capacity to pay
interest and repay principal.  'BB' indicates the least degree of speculation
and 'C' the highest degree of speculation.  While such debt will likely have
some quality and protective characteristics, these are outweighed by large
uncertainties or major risk exposures to adverse conditions.      

    
BB   Debt rated 'BB' has less near-term vulnerability to default than other
     speculative grade debt.  However, it faces major ongoing uncertainties or
     exposure to adverse business, financial, or economic conditions that could
     lead to inadequate capacity to meet timely interest and principal payments.
     The 'BB' rating category is also used for debt subordinated to senior debt
     that is assigned an actual or implied 'BBB-' rating.      

    
B    Debt rate 'B' has greater vulnerability to default but presently has the
     capacity to meet interest payments and principal repayments.  Adverse
     business, financial, or economic conditions would likely impair capacity or
     willingness to pay interest and repay principal.  The 'B' rating category
     also is used for debt subordinated to senior debt that is assigned an
     actual or implied 'BB' or 'BB-' rating.      

    
CCC  Debt rated 'CCC' has a current identifiable vulnerability to default, and
     is dependent on favorable business, financial, and economic conditions to
     meet timely payment of interest and repayment of principal.  In the event
     of adverse business, financial, or economic conditions, it is not likely to
     have the capacity to pay interest and repay principal.  The 'CCC' rating
     category also is used for debt subordinated to senior debt that is assigned
     an actual or implied 'B' or 'B-' rating.      

    
CC   The rating 'CC' is typically applied to debt subordinated to senior debt
     which is assigned an actual or implied 'CCC' rating.      

    
C    The rating 'C' is typically applied to debt subordinated to senior debt
     which is assigned an actual or implied 'CCC-' debt rating.  The 'C' rating
     may be used to cover a situation where a bankruptcy petition has been
     filed, but debt service payments are continued.      

    
CI   Debt rated 'CI' is reserved for income bonds on which no interest is being
     paid.      

    
D    Debt is rated 'D' when the issue is in payment default, or the obligor has
     filed for bankruptcy.  The 'D' rating is used when interest or principal
     payments are not made on the date due, even if the applicable grace period
     has not expired, unless S&P believes that such payments will be made during
     such grace period.      

                                      S-34
<PAGE>
 
    
     Plus (+) or minus (-): The ratings from 'AA' to 'CCC' may be modified by
the addition of a plus or minus sign to show relative standing within the major
rating categories.      

    
C    The letter 'c' indicates that the holder's option to tender the security
     for purchase may be canceled under certain prestated conditions enumerated
     in the tender option documents.      

    
P    The letter 'p' indicates that the rating is provisional.  A provisional
     rating assumes the successful completion of the project financed by the
     debt being rated and indicates that payment of debt service requirements is
     largely or entirely dependent upon the successful timely completion of the
     project.  This rating, however, while addressing credit quality subsequent
     to completion of the project, makes no comment on the likelihood of, or the
     risk of default upon failure of such completion.  The investor should
     exercise his own judgement with respect to such likelihood and risk.      

    
L    The letter 'L' indicates that the rating pertains to the principal amount
     of those bonds to the extent that the underlying deposit collateral is
     federally insured, and interest is adequately collateralized.  In the case
     of certificates of deposit, the letter 'L' indicates that the deposit,
     combined with other deposits being held in the same right and capacity,
     will be honored for principal and pre-default interest up to federal
     insurance limits within 30 days after closing of the insured institution
     or, in the event that the deposit is assumed by a successor insured
     institution, upon maturity.      

    
     *Continuance of the rating is contingent upon S&P's receipt of an executed
     copy of the escrow agreement or closing documentation confirming
     investments and cash flows.      

    
N.R. Not rated.      

    
DEBT OBLIGATIONS OF ISSUERS OUTSIDE THE UNITED STATES AND ITS TERRITORIES are
rated on the same basis as domestic corporate and municipal issues.  The ratings
measure the creditworthiness of the obligor but do not take into account
currency exchange and related uncertainties.      

    
     If an issuer's actual or implied senior debt rating is 'AAA', its
subordinated or junior debt is rated 'AAA' or 'AA+'.  If an issuer's actual or
implied senior debt rating is lower than 'AAA' but higher than 'BB+', its junior
debt is typically rated one designation lower than the senior debt rating.  For
example, if the senior debt rating is 'A', subordinated debt normally would be
rated 'A-'.  If an issuer's actual or implied senior debt rating is 'BB+' or
lower, its subordinated debt is typically rated two designations lower than the
senior debt rating.      

    
INVESTMENT AND SPECULATIVE GRADES      

    
     The term "investment grade" was originally used by various regulatory
bodies to connote obligations eligible for investment  by institutions such as
banks, insurance companies, and savings and loan associations.  Over time, this
term gained widespread usage throughout the investment community.  Issues rated
in the four highest categories, 'AAA', 'AA', 'A', 'BBB', generally are
recognized as being investment grade.  Debt rated 'BB' or below generally is
referred to as speculative grade.  The term "junk bond" is merely a more
irreverent expression for this category of more risky debt.  Neither term
indicates which securities S&P deems worthy of investment, as an investor with a
particular risk preference may appropriately invest in securities that are not
investment grade.      

    
     Ratings continue as a factor in may regulations, both in the U.S. and
abroad, notably in Japan.  For example, the Securities and Exchange Commission
(SEC) requires investment-grade status in order to register debt on Form-3,
which, in turn, is how one offers debt via a Rule 415 shelf registration. The
Federal Reserve Board allows members of the Federal Reserve System to invest in
securities rated in the four highest categories, just as the Federal Home Loan
Bank System permits federally chartered savings and loan associations to invest
in corporate debt with those ratings, and the Department of Labor allows pension
funds to invest in commercial

paper rated in one of the three highest categories.  In similar fashion,
California regulates investments of municipalities and county treasurers,
Illinois limits collateral acceptable for public deposits, and Vermont restricts
investments of insurers and banks.  The New York and Philadelphia Stock
Exchanges fix margin requirements for mortgage securities depending on their
rating, and the securities haircut for commercial paper, debt securities, and
preferred stock that determines net capital requirements is also a function of
the ratings assigned.      

    
SHORT-TERM DEBT RATINGS (may be assigned, for example, to commercial paper,
master demand notes, bank instruments, and letters of credit).

     Prime-1  Issuers rated Prime-1 (or supporting institutions) have a superior
              capacity for repayment of senior short-term promissory
              obligations.  Prime-1 repayment capacity will normally be
              evidenced by many of the following characteristics:      

                       
                   -Leading market positions in well-established industries. 
                                                                                

                       
                   -High rates of return on funds employed.      

                       
                   -Conservative capitalization structures with moderate
                   reliance on debt and ample asset protection.      
 
                       
                   -Broad margins in earnings coverage of fixed financial
                   charges and high internal cash generation.      

                       
                   -Well-established access to a range of financial markets and
                   assured sources of alternate liquidity.      

         
     Prime-2  Issuers rated Prime-2 (or supporting institutions) have a strong
              capacity for repayment of senior short-term debt obligations.
              This will normally be evidenced by many of the characteristics
              cited above but to a lesser degree.  Earnings trends and coverage
              ratios, while sound, may be more subject to variation.
              Capitalization characteristics, while still appropriate, may be
              more affected by external conditions.  Ample alternate liquidity
              is maintained.      

         
     Prime-3  Issuers rated Prime-3 (or supporting institutions) have an
              acceptable ability for repayment of senior short-term obligations.
              The effect of industry characteristics and market compositions may
              be more pronounced.  Variability in earnings and profitability may
              result in changes in the level of debt protection measurements and
              may require relatively high financial leverage.  Adequate
              alternate liquidity is maintained.

     A-1  This designation indicates that the degree of safety regarding timely
          payment is strong.  Those issues determined to have extremely strong
          safety characteristics are denoted with a plus sign (+).      

         
     A-2  Capacity for timely payment on issues with this designation is
          satisfactory.  However, the relative degree of safety is not as high
          as for issues designated "A-1."

     A-3  Issues carrying this designation have adequate capacity for timely
          payment.  They are, however, more vulnerable to the adverse effects of
          changes in circumstances than obligations carrying the higher
          designations.
