borne by investors in shares of the Portfolio. A person who purchases shares
through a financial institution may be charged separate fees by that
institution. The information set forth in the foregoing table and example
relates only to the Portfolio's Class E shares (a class of shares of the
Portfolio). The Portfolio also offers Class A shares which are subject to the
same expenses, except there are different distribution costs. Additional
Information may be found under "The Manager and Shareholder Servicing Agent,"
"The Adviser" and "Distribution."

Road, Wayne, PA 19087 or by calling 1-800-342-5734.     
 
INVESTMENT 
OBJECTIVES AND 
POLICIES _______________________________________________________________________

S&P 500 INDEX     The S&P 500 Index Portfolio seeks to provide investment
PORTFOLIO         results that correspond to the aggregate price and dividend
                  performance of the securities in the Standard & Poor's 500
                  Composite Stock Price Index (the "S&P 500 Index") which is
                  comprised of 500 selected common stocks, most which are
                  listed on the New York Stock Exchange. There is no assurance
                  that the Portfolio will achieve its investment objective.
                     The S&P 500 Index Portfolio's ability to duplicate the
                  performance of the S&P 500 Index will depend to some extent
                  on the size and timing and cashflows into and out of the
                  Portfolio as well as the extent of the Portfolio's expenses.
                     Adjustments made to accommodate cash flows will track the
                  index to the maximum extent possible and may result in
                  brokerage expenses for the Portfolio. Over time, the
                  correlation between the performance of the Portfolio and the
                  S&P 500 Index is expected to be over 0.95. A correlation of
                  1.00 would indicate perfect correlation, which would be
                  achieved when the net asset value of the Portfolio,
                  including the value of its dividend and capital gains
                  distributions, increased or decreased in exact proportion to
                  changes in the S&P 500 Index. An investment in shares of the
                  Portfolio involves risks similar to those of investing in a
                  portfolio consisting of the common stocks of some or all of
                  the companies included in the Index.
                     The Portfolio will normally be invested in all of the
                  stocks which comprise the S&P 500 Index, except when changes
                  are made to the S&P 500 Index itself. The Portfolio's policy
                  is to be fully invested in common stocks, and it is expected
                  that cash reserve items would normally be less than 10% of
                  net assets.
                     The weightings of stocks in the S&P 500 Index are based
                  on each stock's relative total market value, i.e., market
                  price per share times the number of shares outstanding.
                  Because of this weighting, approximately 50% of the S&P 500
                  Index is currently composed of the 50 largest companies in
                  the S&P 500 Index, and the S&P 500 Index currently
                  represents over 65% of the market value of all U.S. common
                  stocks listed on the New York Stock Exchange.
                     World Asset Management, the Portfolio's investment
                  adviser (the "Adviser" or "World"), makes no attempt to
                  "manage" the Portfolio in the traditional sense by using
                  economic, financial or market analysis. The adverse
                  financial situation of a company usually
 
                                                                    4
<PAGE>
 
                  will not result in the elimination of a stock from the
                  Portfolio. However, the Trust reserves the right, without
                  the obligation, to remove an investment from the Portfolio
                  if, in the judgment of World, the merit of the investment
                  has been substantially impaired by extraordinary events or
                  financial conditions. Furthermore, administrative
                  adjustments may be made in the Portfolio from time to time
                  because of mergers, changes in the composition of the S&P
                  500 Index and similar reasons. In certain circumstances,
                  World may exercise discretion in determining whether to
                  exercise warrants or rights issued in respect to portfolio
                  securities or whether to tender portfolio securities
                  pursuant to a tender or exchange offer.
                     The S&P 500 Index Portfolio is not sponsored, endorsed,
                  sold or promoted by Standard & Poor's Corporation ("S&P").

                  to the purchasers of the Portfolio or any member of the
                  public regarding the advisability of investing in index
                  funds or the Portfolio or the ability of the Index to track
                  general stock market performance.
                     S&P DOES NOT GUARANTEE THE ACCURACY AND/OR THE
                  COMPLETENESS OF THE INDEX OR ANY DATA INCLUDED THEREIN. S&P

                  warrants to acquire common stock and securities convertible
                  into common stock.
                     The Portfolio may enter into stock index futures
                  contracts, provided that the value of these contracts does
                  not exceed 20% of the Portfolio's total assets. The
                  Portfolio may purchase futures contracts solely to maintain
                  adequate liquidity to meet its redemption demands while
                  maximizing the level of the Portfolio's assets which are
                  tracking the performance of the Index. In addition, the
                  Portfolio may only purchase those stock index futures
                  contracts--such as futures contracts on the index--that are
                  likely to closely duplicate the performance of the S&P 500
                  Index. The Portfolio also can sell such futures contracts in
                  order to close out a previously established position. The
                  Portfolio will not enter into any stock index futures
                  contract for the purpose of speculation, and will only enter
                  into contracts traded on national securities exchanges with
                  standardized maturity dates. The Portfolio will not purchase
                  or sell futures contracts if immediately thereafter the sum
                  of the amount of margin deposits on its existing futures
                  positions would exceed 5% of its total assets.
 
                                                                    5

                     The Portfolio may invest in the stock of foreign issuers
                  which is traded in the United States. The Portfolio
                  ordinarily will purchase securities of foreign issuers in
                  U.S. markets. However, the Portfolio may purchase securities
                  of foreign issuers directly in foreign markets if the
                  Adviser determines that it is in the best interest of the
                  Portfolio to do so.
                     The Portfolio may invest cash reserves in securities
                  issued by the U.S. Government, its agencies or
                  instrumentalities, bankers' acceptances, commercial paper
                  rated at least A-1 by S&P and/or Prime-1 by Moody's
                  Investors Services, Inc. ("Moody's"), certificates of
                  deposit and repurchase agreements involving such
                  obligations. Such investments will not be used for defensive
                  purposes.

POLICIES _______________________________________________________________________
                     
                  The Portfolio may lend up to 20% of its assets to qualified
                  institutions for the purpose of realizing additional income,
                  however the Portfolio has no present intention to lend its
                  securities. The Portfolio may invest in illiquid securities,
                  however, not more than 10% of the total assets of the
                  Portfolio will be invested in such instruments. The
                  Portfolio may enter into forward commitments, or purchase
                  securities on a when-issued or delayed delivery basis.

INVESTMENT 
LIMITATIONS ____________________________________________________________________
                     
                  The investment objective and investment limitations are
                  fundamental policies of the Portfolio. Fundamental policies
                  cannot be changed with respect to the Trust or a Portfolio
                  without the consent of the holders of a majority of the
                  Trust's or that Portfolio's outstanding shares.     
                     
                  The Portfolio may not:     
                     
                  1. Purchase securities of any issuer (except securities
                     issued or guaranteed by the United States Government, its
                     agencies or instrumentalities) and if, as a result, more
                     than 5% of total assets of the Portfolio would be
                     invested in the securities of such issuer. This
                     restriction applies to 75% of the Portfolio's total
                     assets.     
                  2. Purchase any securities which would cause more than 25%
                     of the total assets of the Portfolio to be invested in
                     the securities of one or more issuers conducting their
                     principal business activities in the same industry,
                     provided that this limitation does not
 
                                                                    6
<PAGE>
 
                   apply to investments in obligations issued or guaranteed by
                   the United States Government or its agencies and
                   instrumentalities.
                     
                  3. 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 will be repaid before
                     making additional investments for the Portfolio and any
                     interest paid on such borrowings will reduce the
                     Portfolio's income.     
                  4. Make loans, except that the Portfolio may 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 Portfolio's
                     total assets, may engage in securities lending as
                     described in this Prospectus and may purchase or hold
                     debt instruments in accordance with its investment
                     objectives and policies.
                  The foregoing percentage limitations will apply at the time
                  of the purchase of a security. Additional investment
                  limitations are set forth in the Statement of Additional
                  Information.
 
THE MANAGER 
AND SHAREHOLDER 
SERVICING AGENT ________________________________________________________________
                     
                  SEI Financial Management Corporation (the "Manager" or the
                  "Transfer Agent"), a wholly-owned subsidiary of SEI
                  Corporation ("SEI"), and the Trust are parties to a
                  management agreement (the "Management Agreement"). Under the
                  terms of the Management Agreement, the Manager is
                  responsible for providing the Trust with overall management
                  services, regulatory reporting, all necessary office space,
                  equipment, personnel and facilities and for acting as
                  transfer agent, dividend disbursing agent, and shareholder
                  servicing agent.     
                     
                     For these services, the Manager is entitled to a fee
                  which is calculated daily and paid monthly at an annual rate
                  of .22% of the average daily net assets of the Portfolio.
                  The Manager may from time to time waive all or a portion of
                  its fee in order to limit the operating expenses of the
                  Portfolio. Any such waiver is voluntary and may be
                  terminated at any time in its sole discretion.     
                     
                     For the fiscal year ended March 31, 1995, the Portfolio
                  paid management fees, after fee waivers, of .12% of its
                  average daily net assets.     
 
                                                                    7

THE ADVISER ____________________________________________________________________

                  World Asset Management ("World" or the "Adviser") is a
                  general partnership organized by Munder Capital Management
                  ("MCM"), a general partnership formed in December, 1994,
                  which engages in investment management and advisory
                  services. As of December 31, 1994 total assets under
                  management of World were $6.0 billion and assets under
                  management of MCM were $29.5 billion. The principal business
                  address for the Adviser is 100 Renaissance Center, 38th
                  Floor, Detroit, Michigan 48275-3040.
                     The Adviser and the Trust are parties to an investment
                  advisory agreement relating to the Portfolios (the "Advisory
                  Agreement").
                     Under the terms of this Advisory Agreement, the Adviser
                  provides the Trust with certain record keeping and
                  management services in connection with the Portfolios
                  including monitoring the indexing systems and determining
                  which securities to purchase and sell in order to keep each
                  Portfolio in balance with its respective index.
                     
                     The Adviser is entitled to a fee, which is calculated
                  daily and paid monthly, at an annual rate of .03% of the
                  average daily net assets of each Portfolio. No monthly
                  payment to the Adviser shall exceed the payment actually
                  made to the Manager pursuant to the current Management
                  Agreement between the Manager and the Trust. For the fiscal
                  year ended March 31, 1995, the Portfolio paid advisory fees,
                  after waivers, of .03% of its average daily net assets to
                  each of Woodbridge Capital Management and World.     
 
DISTRIBUTION ___________________________________________________________________
        
                     
                  SEI Financial Services Company (the "Distributor"), a
                  wholly-owned subsidiary of SEI, serves as the Portfolio's
                  distributor pursuant to a distribution agreement (the
                  "Distribution Agreement") with the Trust. Each Class of the
                  Trust has adopted a distribution plan relating to its shares
                  (the "Class A Plan" and "Class E Plan", respectively),
                  pursuant to Rule 12b-1 under the Investment Company Act of
                  1940 (the "1940 Act").     
                     
                     The Class E Plan provides for reimbursement for expenses
                  incurred by the Distributor in an amount not to exceed .05%
                  of the average daily net assets of the Portfolio on an
                  annualized basis.     
                     
                     Distribution-related expenses reimbursable to the
                  Distributor under the budget include those related to the
                  costs of the printing, reports, prospectuses, notices and
                  similar materials for persons other than current
                  shareholders, advertising expenses and promotional and sales
                  expenses including expenses for travel, communication and
                  compensation and benefits for sales personnel. Distribution
                  expenses not attributable to a specific Portfolio are
                  allocated among each of the portfolios of the Trust based on
                  the     
 
                                                                    8
<PAGE>
 
                     
                  basis of their relative average net assets. The Trust is not
                  obligated to reimburse the Distributor for any expenditures
                  in excess of the approved budget.     
                     
                     The Class E Plan, in addition to providing for the
                  reimbursement payments described above, provides for
                  payments to the Distributor at an annual rate of .15% of the
                  Portfolio's average daily net assets attributable to Class E
                  shares. These payments are characterized as "compensation,"
                  and are not directly tied to expenses incurred by the
                  Distributor. Accordingly, the payments the Distributor
                  receives during any year may be higher or lower than its
                  actual expenses. These additional payments compensate the
                  Distributor for its services in connection with distribution
                  assistance or the provision of shareholder services, and
                  some or all of it may be used to pay financial institutions
                  and intermediaries such as banks, savings and loan
                  associations, insurance companies, and investment
                  counselors, broker-dealers (including the Distributor's
                  affiliates and subsidiaries) for services or reimbursement
                  of expenses incurred in connection with distribution
                  assistance or the provision of shareholder services.
                  Currently, the Distributor is taking this additional
                  compensation payment under the Class E Plan at a rate of
                  .15% of the Portfolio's average daily net assets, on an
                  annualized basis, attributable to Class E shares.     
                     
                     It is possible that an institution may offer different
                  classes of shares to its customers and thus receive
                  different compensation with respect to different classes.
                  These financial institutions may also charge separate fees
                  to their customers.     
                     
                     The Trust may execute brokerage or other agency
                  transactions through the Distributor for which the
                  Distributor may receive compensation.     
                     
                     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
                  Portfolio. Such promotional incentives will be offered
                  uniformly to all shares of the Portfolio, and also will be
                  offered uniformly to all dealers, predicated upon the amount
                  of shares of the Portfolio sold by such dealer.     
                         
PURCHASE AND 
REDEMPTION 
OF SHARES   ____________________________________________________________________
                     
                  Financial institutions may acquire shares of the Portfolio
                  for their own account or as a record owner on behalf of
                  fiduciary, agency or custody accounts by placing orders with
                  the Transfer Agent. Institutions that use certain SEI
                  proprietary systems may place orders electronically through
                  those systems. State securities laws may require banks and
                  financial institutions purchasing shares for their customers
                  to register as dealers pursuant to state laws. Financial
                  institutions may impose an earlier cut-off time for receipt
                  of purchase orders directed through them to allow for
                  processing and transmittal of these orders to     
 
                                                                    9

                  the Transfer Agent for effectiveness the same day. Financial
                  institutions which purchase shares for the accounts of their
                  customers may impose separate charges on these customers for
                  account services. Shares of the Portfolio are offered only
                  to residents of states in which the shares are eligible for
                  purchase.     
                     
                     Shares of the Portfolio may be purchased or redeemed on
                  days on which the New York Stock Exchange is open for
                  business ("Business Days"). However, fund shares cannot be
                  purchased by Federal Reserve wire on federal holidays
                  restricting wire transfers.     
                     Shareholders who desire to purchase 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. 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. 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 shareholders to accept such
                  purchase order.
                     
                     Purchases will be made in full and fractional shares of
                  the Portfolio calculated to three decimal places. The Trust
                  will send shareholders a statement of shares owned after
                  each transaction. The purchase price of shares is the net
                  asset value next determined after a purchase order is
                  received and accepted by the Trust. The net asset value per
                  share of the Portfolio is determined by dividing the total
                  market value of the Portfolio's investment and other assets,
                  less any liabilities, by the total outstanding shares of the
                  Portfolio. 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.
                      
                     The market value of each portfolio security is obtained
                  by the Manager from an independent pricing service. The
                  pricing service relies primarily on prices of actual market
                  transactions as well as trader quotations. However, the
                  pricing service may use a matrix system to determine
                  valuations of equity and fixed income securities. This
                  system considers such factors as security prices, yields,
                  maturities, call features, ratings and developments relating
                  to specific securities in arriving at valuations. The
                  pricing service may also provide market quotations. The
                  procedures of the pricing service and its valuations are
                  reviewed by the officers of the Trust under the general
                  supervision of the Trustees.
                     
                     Shareholders who desire to redeem shares of the Portfolio
                  must place their redemption orders with the Transfer Agent
                  prior to 4:00 p.m. Eastern time on any Business Day. The
                  redemption price is the net asset value per share of the
                  Portfolio next determined after receipt by the Transfer
                  Agent of the redemption order. Payment on redemption will be
                  made as promptly as possible and, in any event, within seven
                  days after the redemption order is received.     
                     
                     Shares of the Portfolio may be purchased in exchange for
                  securities included in the Portfolio subject to the
                  Manager's or the Adviser's determination that the securities
                  are acceptable. Securities accepted in an exchange will be
                  valued at market value. All accrued interest and
                  subscription of other rights which are reflected in the
                  market price of

                  accepted securities at the time of valuation become the
                  property of the Trust and must be delivered by the
                  Shareholder to the Trust upon receipt from the issuer.
                     The Manager or Adviser will not accept securities for a
                  Portfolio unless (1) such securities are appropriate in the
                  Portfolio at the time of the exchange; (2) such an exchange
                  will not cause the Portfolio's weightings to become
                  materially imbalanced with respect to the weightings of the
                  securities included in the Index; (3) such securities are
                  acquired for investment and not for resale; (4) the
                  Shareholder represents and agrees that all securities
                  offered to the Trust for the Portfolio are not subject to
                  any restrictions upon their sale by the Portfolio under the
                  Securities Act of 1933, or otherwise; (5) such securities
                  are traded on the American Stock Exchange, the New York
                  Stock Exchange or on NASDAQ in an unrelated transaction with
                  a quoted sales price on the same day the exchange valuation
                  is made or, if not listed on such exchanges or on NASDAQ,
                  have prices available from an independent pricing service
                  approved by the Trust's Board of Trustees; and (6) the
                  securities may be acquired under the investment restrictions
                  applicable to the Portfolio.
                     Purchase and redemption orders may be placed by
                  telephone. Neither the Trust nor the Trust's 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, Shareholders may
                  experience difficulties placing redemption orders by
                  telephone, and may wish to consider placing orders by other
                  means.     
 
PERFORMANCE ____________________________________________________________________
                     
                  From time to time, the Portfolio may advertise yield and
                  total return. These figures will be based on historical
                  earnings and are not intended to indicate future
                  performance. No representation can be made concerning actual
                  future yields or returns. The yield of a Portfolio refers to
                  the income generated by a hypothetical investment in the
                  Portfolio over a thirty day period. This income is then
                  "annualized," i.e., the income over thirty days is assumed
                  to be generated over one year and is shown as a percentage
                  of the investment.     
                     
                     The total return of the Portfolio refers to the average
                  compounded rate of return on a hypothetical investment for
                  designated time periods, 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 Portfolio may periodically compare its performance to
                  the performance of: other mutual funds tracked by mutual
                  fund rating services (such as Lipper Analytical); financial
                  and business publications and periodicals; broad groups of
                  comparable mutual     
 
                                                                    11

                  funds; unmanaged indices which may assume investment of
                  dividends but generally do not reflect deductions for
                  administrative and management costs; or to other investment
                  alternatives. The Portfolio may quote Morningstar, Inc., a
                  service that ranks mutual funds on the basis of risk-
                  adjusted performance. The Portfolio 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 Portfolio may also quote financial and business
                  publications and periodicals as they relate to fund
                  management, investment philosophy and investment techniques.
                         
                     The Portfolio 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.     
                     
                     The performance on Class A shares will normally be higher
                  than that on the Class E shares of the Portfolio because of
                  the additional distribution expenses charged to Class E
                  shares.     
 
TAXES __________________________________________________________________________
                     
                  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 income tax treatment of the
                  Portfolio or its shareholders. Accordingly, shareholders are
                  urged to consult their tax advisers regarding specific
                  questions as to federal, state and local taxes. State and
                  local tax consequences of an investment in the Portfolio may
                  differ from the federal income tax consequences described
                  below. Additional information concerning taxes is set forth
                  in the Statement of Additional Information.     
                  
Tax Status of     The Portfolio is treated as a separate entity for federal
the Portfolio     income tax purposes and is not combined with the Trust's
                  other portfolios. The Portfolio intends 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 company
                  taxable income and net capital gains (the excess of net
                  long-term capital gain over net short-term capital losses)
                  distributed to shareholders.     
                     
Tax Status of     The Portfolio distributes substantially all of its net
Distributions     investment income (including net short-term capital gains)
                  to shareholders. Dividends from the Portfolio's net
                  investment income are taxable to its shareholders as
                  ordinary income (whether received in cash or in additional
                  shares) and will not qualify for the deduction for the
                  corporate dividends-received deduction. Distributions of net
                  capital gains are taxable to shareholders as long-term
                  capital gains. The Portfolio provides annual reports to
                  shareholders of the federal income tax status of all
                  distributions.     
 
                                                                    12

                     Dividends declared by the Portfolio 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 Portfolio and received by the Shareholders on
                  December 31 of the year declared if paid by the Portfolio at
                  any time during the following January.     
                     
                     The Portfolio intends to make sufficient distributions to
                  avoid liability for the federal excise tax.     
                     
                     Investment income received by the Portfolio from sources
                  within foreign countries may be subject to foreign income
                  taxes withheld at the source. To the extent that the
                  Portfolio is liable for foreign income taxes so withheld,
                  the Portfolio intends to operate so as to meet the
                  requirements of the Code to pass through to the shareholders
                  credit for foreign income taxes paid. Although the Portfolio
                  intends to meet Code requirements to pass through credit for
                  such taxes, there can be no assurance that the Portfolio
                  will be able to do so.     
                     Sale, exchange or redemption of Portfolio shares is a
                  taxable transaction to the shareholder.
 
GENERAL 
INFORMATION ____________________________________________________________________
                     
The Trust         The Trust was organized as a Massachusetts business trust
                  under a Declaration of Trust dated March 6, 1985. The
                  Declaration of Trust permits the Trust to offer separate
                  series of shares and different classes of each portfolio. In
                  addition to the Portfolio, the Trust consists of the Bond
                  Index Portfolio. All consideration received by the Trust for
                  shares of any class of any portfolio and all assets of such
                  portfolio or class belong to that portfolio or class,
                  respectively, and would be subject to the 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, litigation and other
                  extraordinary expenses, brokerage costs, interest charges,
                  taxes and organization expenses.

Trustees of the   The management and affairs of the Trust are supervised by
Trust             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. The shareholders of each Portfolio or class will vote
                  separately on matters pertaining solely to that Portfolio or
                  class, such as any distribution plan. 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
 
                                                                    13

                  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 statements semi-
                  annually and audited financial statements annually. The
                  Trust furnishes proxy statements and other reports to
                  shareholders of record.     

Shareholder       Shareholder inquiries should be directed to the Manager, SEI
Inquiries         Financial Management Corporation, 680 East Swedesford Road,
                  Wayne, PA 19087.
                     
Dividends         Substantially all of the net investment income (exclusive of
                  capital gains) of the Portfolio is periodically declared and
                  paid as a dividend. Dividends are paid currently on a
                  quarterly basis. Currently, net capital gains (the excess of
                  net long-term capital gain over net short-term capital loss)
                  realized, if any, will be 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 Manager at least 15 days prior to the
                  distribution.
                     
                     Dividends and capital gains of the Portfolio 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 a dividend or capital
                  gains distributions, a shareholder will pay the full price
                  for the share and receive some portion of the price back as
                  a taxable dividend or distribution.     
                     
                     The dividends on Class A shares of the Portfolio are
                  normally higher than those on the Class E shares because of
                  the additional distribution expenses charged to Class E
                  shares.

DESCRIPTION OF 
PERMITTED 
INVESTMENTS AND 
RISK FACTORS   _________________________________________________________________
                     
                  The following is a description of the permitted investment
                  practices for the Portfolio, and the associated risk
                  factors:     

Bankers'          Bankers' acceptances are bills of exchange or time drafts
Acceptances       drawn on and accepted by a commercial bank. Bankers'
                  acceptances are used by corporations to finance the shipment
                  and storage of goods and to furnish dollar exchange.
                  Maturities are generally six months or less.

Certificates of   Certificates of deposit are interest bearing instruments
Deposit           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 have penalties
                  for early withdrawal.

Commercial        Commercial paper is a term used to describe unsecured short-
Paper             term promissory notes issued by banks, municipalities,
                  corporations and other entities. Maturities on these issues
                  vary from a few to 270 days.

Equity            Investments in equity securities in general are subject to
Securities        market risks that may cause their prices to fluctuate over
                  time. The value of convertible equity securities is also
                  affected by prevailing interest rates, the credit quality of
                  the issuer and any call provision. Fluctuations in the value
                  of equity securities in which the Portfolio invests will
                  cause the net asset value of the Portfolio to fluctuate.
                     
Illiquid          Illiquid securities are securities which cannot be disposed
Securities        of within seven business days at approximately the price at
                  which they are being carried on the Trust's books. An
                  illiquid security includes a demand instrument with a demand
                  notice period exceeding seven days, where there is no
                  secondary market for such security and repurchase agreements
                  with durations (or maturities) over 7 days in length.     
                     
Repurchase        Repurchase agreements are agreements by which the Portfolio
Agreements        obtains a security and simultaneously commits to return the
                  security to the seller at an agreed-upon price on an agreed-
                  upon date. The Custodian will hold the security as
                  collateral for the repurchase agreement. The Portfolio bears
                  a risk of loss in the event the other party defaults on its
                  obligations and the Portfolio is delayed or prevented from
                  its right to dispose of the collateral or if the Portfolio
                  realizes a loss on the sale of the collateral. The Portfolio
                  will enter into repurchase agreements only with financial
                  institutions deemed to present minimal risk of bankruptcy
                  during the term of the agreement based on established
                  guidelines. Repurchase agreements are considered loans under
                  the 1940 Act.     

Securities of     There are certain risks connected with investing in foreign
Foreign Issuers   securities. These include risks of adverse political and
                  economic developments (including possible governmental
                  seizure or
 
                                                                    15

                  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 Fund's
                  investments denominated in foreign currencies will depend on
                  the relative strengths of those currencies and the U.S.
                  dollar, and a Fund may be affected favorably or unfavorably
                  by changes in the exchange rates or exchange control
                  regulations between foreign currencies and the U.S. dollars.
                  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
                  Fund.
Stock Index       A stock index futures contract is a bilateral agreement
Futures           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 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 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, call "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.
                     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.
                     In considering the proposed use of futures contracts,
                  particular note should be taken that futures contracts
                  relate to the anticipated levels at some point in the
                  future, not to the current level of the underlying
                  instrument. Thus trading of stock index futures may not
                  reflect the trading of the securities which are used to
                  formulate an index or even actual fluctuations in the
                  relevant index itself. There is, in addition, a risk that
                  movements in the price of futures contracts will not
                  correlate with the movement in prices of the stock index
                  being tracked.
Time Deposits     Time deposits are non-negotiable receipts issued by a bank
                  in exchange for the deposit of funds. Like a certificate of
                  deposit, a time deposit earns a specified rate of interest
                  over a
 
                                                                    16
<PAGE>
 
                  definite period of time; however, it cannot be traded in the
                  secondary market. Time deposits are considered to be
                  illiquid securities.

U.S. Government   Obligations issued or guaranteed by agencies of the United
Agencies          States 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 United States
                  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), and others are
                  supported by the right of the issuer to borrow from the
                  Treasury (e.g., Federal Farm Credit Bank), and still others
                  are supported only by the credit of the instrumentality
                  (e.g., Federal National Mortgage Association). Guarantees of
                  principal by agencies or instrumentalities of the United
                  States 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 Portfolios' shares.

Warrants          Warrants are instruments giving holders the right, but not
                  the obligation, to buy shares of a company at a given price
                  during a specified period.
                     
When-Issued and   When-issued or delayed delivery basis transactions involve
Delayed           the purchase of an instrument with payment and delivery
Delivery          taking place in the future. Delivery of and payment for
Securities        these securities may occur a month or more after the date of
                  the purchase commitment. The Portfolio will maintain with
                  the custodian a separate account with liquid, high grade
                  debt securities or cash in an amount at least equal to these
                  commitments. The interest rate realized on these securities
                  is fixed as of the purchase date, and no interest accrues to
                  the Portfolio before settlement. These securities are
                  subject to market fluctuation due to changes in market
                  interest rates, and it is possible that the market value at
                  the time of settlement could be higher or lower than the
                  purchase price if the general level of interest rates has
                  changed. Although the Portfolio generally purchases
                  securities on a when-issued or forward commitment basis with
                  the intention of actually acquiring securities for its
                  portfolio, the Portfolio may dispose of a when-issued
                  security or forward commitment prior to settlement if it
                  deems appropriate.

THE TRUST

SEI Index Funds (the "Trust") is a diversified, open-end management investment
company established under Massachusetts law as a Massachusetts business trust
under a Declaration of Trust dated March 6, 1985. The Declaration of Trust
permits the Trust to offer separate series of units of beneficial interest
("shares") and separate classes of series. Except for differences between Class
A and Class E shares of the S&P 500 Index Portfolio pertaining to distribution
plans, each share of each portfolio represents an equal proportionate interest
in that portfolio with each other share of that portfolio.

to track general stock market performance.  S&P's only relationship to the
licensee, the Trust, is the licensing of certain trademarks and trade names of
S&P and of the S&P 500 Index which is determined, composed and calculated by S&P
without regard to the licensee or the Portfolio.  S&P has no obligation to take
the needs of the licensee or the owners of the Portfolio into consideration in
determining, composing or calculating the S&P 500 Index.  S&P is not responsible

DESCRIPTION OF CERTAIN PERMITTED INVESTMENTS

The following information supplements the information about permitted
investments set forth in the corresponding Prospectus for the relevant
Portfolio.

Bank Obligations - The Portfolios may invest in bank obligations of U.S.
commercial banks or savings and loan institutions.  The bank obligations which
the Portfolios may buy will include certificates of deposit, time deposits and
bankers' acceptances.  A time deposit is an account containing a currency
balance pledged to remain at a particular bank for a specified period in return
for payment of interest.  A bankers' acceptance is a bill of exchange guaranteed
by a bank or trust company for payment within one to six months.  Bankers'
acceptances are used to provide manufacturers and exporters with capital to
operate between the time of manufacture or export and payment by the purchaser.

                                       2
<PAGE>
 
Mortgage Pass-Through Securities - The Bond Index Portfolio may purchase
securities representing interests in mortgage pools guaranteed by GNMA, FNMA,
FHLMC, conventional mortgage-pass through obligations, and FHA-insured project
mortgage pools.

GNMA is a wholly-owned U.S. Government corporation which guarantees the timely
payment of principal and interest.  The market value and interest yield of these
instruments can vary due to market interest rate fluctuations and early
prepayments of underlying mortgages.  These securities represent ownership in a
pool of federally insured mortgage loans.  GNMA certificates consist of
underlying mortgages with a maximum maturity of 30 years.  However, due to
scheduled and unscheduled principal payments, GNMA certificates have a shorter
average maturity and, therefore, less principal volatility than a comparable 
30-year bond. Since prepayment rates vary widely, it is not possible to predict
accurately the average maturity of a particular GNMA pool. The scheduled monthly
interest and principal payments relating to mortgages in the pool will be
"passed through" to investors. GNMA securities differ from conventional bonds in
that principal is paid back to the certificate holders over the life of the loan
rather than at maturity. As a result, the Portfolio will receive monthly
scheduled payments of principal and interest. In addition, the Portfolio may
receive unscheduled principal payments representing prepayments on the
underlying mortgages. Any prepayments will be reinvested at the then prevailing
interest rate.

Repurchase Agreements - The Portfolios may invest in repurchase 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.  A Portfolio bears a risk of loss in the event that the other party to
a repurchase agreement defaults on its obligations and the Portfolio is delayed
or prevented from exercising its rights to dispose of the collateral securities.
The Administrator enters into repurchase agreements only with financial
institutions which it deems to present minimal risk of bankruptcy during the
term of the agreement based on guidelines which are periodically reviewed by the
Board of Trustees.  These guidelines currently permit a Portfolio to enter into
repurchase agreements only with primary government securities dealers, as
recognized by the Federal Reserve Bank of New York, which have minimum net
capital of $100 million or 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 a Portfolio will
provide that the 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 Administrator monitors compliance with this
requirement.

Under all repurchase agreements entered into by a Portfolio, the Custodian or
its agent must take possession of the underlying collateral.  However, if the
seller defaults, a Portfolio could realize a loss on the sale of the underlying
security to the extent that the proceeds of sale including accrued interest are
less than the resale price provided in the agreement including interest.  In
addition, even though the Federal Bankruptcy Code provides protection for most
repurchase agreements, if the seller should be involved in bankruptcy or
insolvency proceedings, the Portfolio may incur delay and costs in selling the
underlying security or may suffer a loss of principal and interest if the
Portfolio is treated as an unsecured creditor and required to return the
underlying security to the seller's estate.

Securities Lending - In order to generate additional income, the Portfolios may
lend securities in which it is invested 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 securities lent.  Such loans
will not be made if, as a result, the aggregate amount of all outstanding
securities loans for a Portfolio exceeds 20% of the value of the Portfolio's
total assets taken at current value.  The Portfolio will continue to receive
income on the securities lent while simultaneously earning interest on the
investment of the cash collateral in U.S. Government securities.  However, the
Portfolios will normally pay lending fees to such broker-dealers and related
expenses from the interest earned on invested collateral.  There may be risks of
delay in receiving

                                       3
<PAGE>
 
additional collateral or risks of delay in recovery of the securities or even
loss of rights in the collateral should the borrower of the securities fail
financially.  However, loans are made only to borrowers deemed by the
Administrator to be of good standing and when, in the judgment of the
Administrator, the consideration which can be earned currently from such loans
justifies the attendant risk.  Any loan may be terminated by either party upon
reasonable notice to the other part.  The Portfolios will vote the securities
while the collateral is outstanding.

Stock Index Futures - The S&P 500 Index Portfolio may invest in stock index
futures.  The nature of initial and variation margin in futures transactions is
different from that of margin in security transactions in that futures contract
margin does not involve the borrowing of funds to finance the transactions.
Rather, the margin is in the nature of a performance bond or good-faith deposit
on the contract that is returned to the Portfolio upon termination of the
contract, assuming all contractual obligations have been satisfied.  Initial
margin generally is equal to approximately 2.4% of the contract value which
would be deposited in a segregated account in the name of the futures broker.
Positions in futures contracts may be closed only on an exchange or board of
trade providing a secondary market for such futures contracts.  The value of the
contract usually will vary in direct proportion to the total face value.  Market
value of a futures position is defined as the closing value of the Index
multiplied by 500 times the number of contracts held.

The Portfolio's ability to effectively utilize futures trading depends on
several factors.  First, it is possible that there will not be a perfect price
correlation between the futures contracts and their underlying stock index. In
addition, the purchase of a futures contract involves the risk that the
Portfolio could lose more than the original margin deposit required to initiate
a futures transaction.

In considering the proposed use of futures contracts, particular note should be
taken that futures contracts relate to the anticipated levels at some point in
the future not to the current level of the underlying instrument; thus, for
example, trading of stock index futures may not reflect the trading of the
securities which are used to formulate an index or even actual fluctuations in
the relevant index itself.  There is, in addition, a risk that movements in the
price of futures contracts will not correlate with the movement in prices of the
stock index being tracked.  There may be several reasons unrelated to the value
of the underlying securities which causes this situation to occur.  First, all
participants in the futures market are subject to initial and variation margin
requirements. If, to avoid meeting additional margin deposit requirements or for
other reasons, investors choose to close a significant number of futures
contracts through offsetting transactions, distortions in the normal price
relationship between the securities markets and the futures markets may occur.
Second, because the deposit requirements in the futures market are less onerous
than margin requirements in the securities market, there may be increased
participation by speculators in the futures market which may also cause
temporary price distortions.

The Portfolio has undertaken to restrict its futures contract trading as
follows:  First, the Portfolio will not engage in transactions in futures
contracts for speculative purposes.  Second, the Portfolio will not purchase or
sell futures contracts if immediately thereafter the sum of the amount of margin
deposits on its existing futures positions would exceed 5% of the Portfolio's
total assets.  Third, the Portfolio will not market itself to the public as a
commodity pool or otherwise as a vehicle for trading in the commodities futures
or commodity options markets.  Fourth, the Portfolio will disclose to all
prospective shareholders the purpose of and limitations on its commodity futures
trading.  Fifth, the Portfolio will submit to the Commodity Futures Trading
Commission ("CFTC") special calls for information.  Accordingly, registration as
a commodities pool operator with the CFTC is not expected to be required.

U.S. Government Securities - The Portfolios may invest in U.S. Government
Securities which include bills, notes and bonds issued by the United States
Treasury, obligations issued or guaranteed by agencies of the United States
Government including, among others, Export Import Bank of the United States,
Farmers Home Administration, Federal Farm Credit Bank, Federal Housing
Administration, Maritime

                                       4

Administration, Small Business Administration, and The Tennessee Valley
Authority and obligations issued or guaranteed by instrumentalities of the
United States Government, among others, Federal Home Loan Banks, Federal Home
Loan Mortgage Corporation, Federal Intermediate Credit Banks, Federal Land
Banks, Federal National Mortgage Association and the United States Postal
Service.  Some of these securities are supported by the full faith and credit of
the United States Treasury (e.g., Government National Mortgage Association),
others are supported by the right of the issuer to borrow from the Treasury
(e.g., Federal Farm Credit Bank) and still others are supported only by the
credit of the instrumentality (e.g., Federal National Mortgage Association).
Guarantees of principal by agencies or instrumentalities of the United States
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.

When-Issued Securities - The Bond Index Portfolio may purchase debt obligations
on a when-issued basis, in which case delivery and payment normally take place
within 45 days after the date of the commitment to purchase.  The 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 if it is deemed advisable.  The when-issued securities are
subject to market fluctuation, and no interest accrues to the purchaser during
the period prior to settlement.  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 which case there could be an unrealized loss at
the time of delivery.

The Portfolio will establish a segregated account with a custodian and maintain
high quality, liquid assets in an amount at least equal in value to the
Portfolio's commitments to purchase when-issued securities.  If the value of
these assets declines, the Portfolio 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.


INVESTMENT LIMITATIONS

The Portfolios may not:

1.   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 the Portfolio taken at current value at the
     time of the incurrence of such loan and, as to the S&P 500 Index Portfolio,
     in connection with stock index futures trading as provided in the
     Prospectus and this Statement of Additional Information.

2.   Invest in companies for the purpose of exercising control.

3.   Purchase or sell real estate, real estate limited partnership interests,
     commodities or commodities contracts. However, subject to its permitted
     investments, a Portfolio may purchase obligations issued by companies which
     invest in real estate, commodities or commodities contracts.

4.   Make short sales of securities, maintain a short position or purchase
     securities on margin, except that the Trust may obtain short-term credits
     as necessary for the clearance of security transactions.

                                       5
<PAGE>
 
5.   Act as an underwriter of securities of other issuers except as it may be
     deemed an underwriter in selling a portfolio security.

6.   Purchase securities of other investment companies except as permitted by
     the Investment Company Act of 1940 and the rules and regulations thereunder
     and may only purchase securities of money market funds.

7.   Issue senior securities (as defined in the Investment Company Act of 1940)
     except in connection with permitted borrowings as described in the
     Prospectus and this Statement of Additional Information or as permitted by
     rule, regulation or order of the Securities and Exchange Commission
     ("SEC").

8.   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.

9.   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.

10.  Purchase warrants, puts, calls, straddles, spreads or combinations thereof.

11.  Invest in interests in oil, gas or other mineral exploration or development
     programs.

12.  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 or
exists immediately after and as a result of a purchase of such security.  These
investment limitations and the investment limitations in the Prospectus are
fundamental policies of the Trust and may not be changed without Shareholder
approval.   Notwithstanding the Portfolios' limited right to purchase securities
of other investment companies, the Adviser has no intention to purchase any
securities of other investment companies.


THE MANAGER AND SHAREHOLDER SERVICING AGENT

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

The continuance of the Management Agreement must be specifically approved at
least annually (i) by the vote of a majority of the Trustees or by the vote of a
majority of the outstanding voting securities of the Portfolio, and (ii) by the
vote of a majority of the Trustees of the Trust who are not parties to the
Management Agreement or an "interested person" (as that term is defined in the
Investment Company Act of 1940) of any party thereto, cast in person at a
meeting called for the purpose of voting on such approval.  The Management
Agreement is terminable at any time without penalty by the Trustees of the

                                       6
<PAGE>
 
Trust, by a vote of a majority of the outstanding shares of a Portfolio or by
the Manager on not less than 30 days nor more than 60 days written notice.  This
Agreement shall not be assignable by either party without the written consent of
the other party.

The Manager, a wholly-owned subsidiary of SEI Corporation ("SEI"), was organized
as a Delaware corporation in 1969 and has its principal business offices at 680
E. Swedesford Road, Wayne, Pennsylvania 19087.  Alfred P. West, Jr., Henry H.
Greer, Carmen V. Romeo, and Robert A. Nesher constitute the Board of Directors
of the Manager.  Mr. West serves as the Chairman of the Board of Directors and
Chief Executive Officer of SEI, the Manager and the Distributor.  Mr. Greer
serves as a Director, President and the Chief Operating Officer of SEI, the
Manager and the Distributor.  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.  The Manager also serves as manager to the following other
institutional mutual funds:  SEI Liquid Asset Trust; SEI Tax Exempt Trust; SEI
Institutional Managed Trust; SEI International Trust; SEI Daily Income Trust;
SEI Insurance Investment Products Trust; CrestFunds, Inc.; Stepstone Funds; The
Compass Capital Group; FFB Lexicon Funds; The Pillar Funds; STI Classic Funds;
CUFund; CoreFunds, Inc.; The Advisors' Inner Circle Fund; First American
Investment Funds, Inc.; PBHG Funds, Inc.; First American Funds, Inc.; Rembrandt
Funds; The Arbor Fund; 1784 Funds; Marquis Funds; Inventor Funds, Inc.; The
Achievement Funds Trust; Bishop Street Funds, Nationar Funds, Inc. and Morgan
Grenfell Investment Trust.

If operating expenses of either Portfolio exceed limitations established by
certain states, the Manager will pay such excess.  The Manager will not be
required to bear expenses of the Portfolios to an extent which would result in
the Portfolio'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.

For the fiscal years ended March 31, 1993, 1994 and 1995, the Manager received
fees of $1,203,817, $1,206,920, and $933,762, respectively, from the S&P 500
Index Portfolio, of which $562,746, $436,000, and $404,164, respectively, was
waived. For the fiscal years ended March 31, 1993, 1994, and 1995, the Manager
received fees of $177,360, $216,261, and $174,635, from the Bond Index
Portfolio, of which $34,425, $55,472, and $49,700, respectively, was waived.


THE ADVISER

On March 8, 1995, the Portfolios' shareholders approved the Trust's advisory
agreement with World Asset Management (the "Adviser"), under which World Asset
Management will continue to serve as Investment Adviser to the Portfolios.

The Adviser is a general partnership formed under Delaware law.  Munder Capital
Management ("MCM"), a newly-formed general partnership, and Munder Trust are its
general partners.  MCM was created by a merger between the Trust's former
investment administrator, Woodbridge Capital Management, Inc. ("Woodbridge"),
World Asset Management, Inc. and Munder Capital Management, Inc.  As of March
31, 1995, total assets under management of the Adviser exceeded $6.7 billion,
and assets managed by MCM totalled approximately $31.3 billion.  The principal
address for the Adviser is 100 Renaissance Center, Detroit, Michigan 48243.

The Investment Advisory Agreement provides that the Adviser shall not be
protected against any liability 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.

                                       7
<PAGE>
 
The continuance of the Investment Advisory Agreement after the first two (2)
years must be specifically approved at least annually (i) by the vote of a
majority of the outstanding shares of the Portfolios or by the Trustees, and
(ii) by the vote of a majority of the Trustees who are not parties to such
Investment Advisory  Agreement or "interested persons" of any party thereto,
cast in person at a meeting called for the purpose of voting on such approval.
The Investment 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 the Portfolio, by a majority of the outstanding
shares of the Portfolio, on not less than 30 days nor more than 60 days written
notice to the Adviser, or by the Adviser on 90 days written notice to the Trust.

World Asset Management, the Adviser to the Portfolios, is a general partnership
organized by Munder Capital Management, a general partnership formed in
December, 1994, which engages in investment management and advisory services.
Counsel to World has advised the Trust that the Adviser may perform the services
contemplated by the Investment Advisory Agreement without violation of
applicable banking laws or regulations.  Such counsel has pointed out, however,
that future changes in either federal or state statutes and regulations relating
to the permissible activities of banks or trust companies, as well as judicial
or administrative decisions or interpretations, could prevent the Adviser from
continuing to perform such services for the Trust.  In such event, the Trustees
would seek to retain other administrators, which would require approval by a
majority of the outstanding shares of each Portfolio.

The Adviser is entitled to a fee for its investment advisory services which is
calculated daily and paid monthly at an annual rate of .03% of the average daily
net assets of each Portfolio.  No monthly payment to the Adviser shall exceed
the payment actually made to the Manager pursuant to the current Management
Agreement between the Manager and the Trust.  For the fiscal year ended March
31, 1993, the S&P 500 Index Portfolio and the Bond Index Portfolio incurred fees
of $164,156.87 and $15,202.32, respectively, of which $33,024.55 and $2,771.47,
respectively, was paid to Manufacturers Bank, N.A., the former investment
administrator to the Trust, for services rendered to the Trust until June 1992
and $131,132.32 and $412,430.85, respectively, was paid to Woodbridge for its
services rendered for the remaining portion of the fiscal year.

For the fiscal years ended March 31, 1994 and 1995, the Adviser and its
predecessor, Woodbridge, received fees of $164,581 and $127,331, respectively,
respectively, from the S&P 500 Index Portfolio, and fees of $18,537 and $14,969,
respectively, from the Bond Index Portfolio.


DISTRIBUTION

The Distribution Agreement is renewable annually and may be terminated by the
Distributor, a majority vote of the Disinterested Trustees or by a majority vote
of the outstanding securities of the Trust upon not more than 60 days written
notice by either party.  No compensation is paid to the Distributor under the
Distribution Agreement.  The Distributor, SEI Financial Services Company, is a
wholly-owned subsidiary of SEI.

The Trust has adopted a Distribution Plan for Class A and Class E shares of the
Portfolios (the "Plans") in accordance with the provisions of Rule 12b-1 under
the Investment Company Act of 1940 which regulates circumstances under which an
investment company may directly or indirectly bear expenses relating to the
distribution of its shares.  In this connection, the Board of Trustees has
determined that the Plans and Distribution Agreement are in the best interests
of Shareholders.  Continuance of the Plans 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 and have no financial interest in the Plans or any
related agreement ("Qualified Trustees").  The Plans require that quarterly
written reports of amounts spent under the Plans and the purposes of such
expenditures be furnished and reviewed by the Trustees.  The Plans may not

                                       8
<PAGE>
 
be amended to increase materially the amount which may be spent thereunder
without approval by a majority of the outstanding shares of the Trust.  All
material amendments of the Plans will require approval by a majority of the
Trustees of the Trust and of the Qualified Trustees.

The Distribution Agreement and the Class E Distribution Plan provide for
reimbursement of expenses incurred by the Distributor in an amount not to exceed
 .05% of the S&P 500 Index Portfolio's average daily net assets on an annualized
basis, provided those expenses are permissible as to both type and amount under
a budget. This budget must be approved and monitored quarterly the Trustees,
including Qualified Trustees. The Class E Plan provides for additional payments
for distribution and shareholder services as described below.

The Class E Plan, in addition to providing for the reimbursement payments
described above, provides for payments to the Distributor at an annual rate of
 .15% of the Class E average daily net assets.  These additional payments are
characterized as "compensation," and are not directly tied to expenses incurred
by the Distributor; the payments the Distributor receives during any year may
therefore be higher or lower than its actual expenses.  The Distributor may use
these additional payments to compensate Class E shareholders that are
institutions that provide administrative services to their customers.  These
institutions may also charge separate fees for these and related services.  It
is possible that an institution may offer different classes of shares to its
customers and thus receive compensation with respect to different classes.
Certain Class E shareholders offering shares to their customers may be required
to register as dealers pursuant to state laws.

Distribution expenditures by the Portfolios will be the lesser of the approved
budget or actual expenditures by the Distributor.  For the fiscal year ended
March 31, 1993, the S&P 500 Index Portfolio and the Bond Index Portfolio
incurred distribution expenses of $273,958 and $23,747 under the Plan or .05% of
net assets, respectively, during such period.  These expenditures included
$141,432 and $4,478, respectively, for sales expenses; $53,356 and $11,459,
respectively, for printing and mailing costs; and $79,170 and $7,810,
respectively, for costs associated with registration fees.

For the fiscal year ended March 31, 1994, the S&P 500 Index Portfolio and the
Bond Index Portfolio incurred distribution expenses of $210,394 and $26,265
under the Plan or .05% of net assets, respectively, during such period.  These
expenditures included $170,537 and $13,104, respectively, for sales expenses;
and $39,857 and $13,161, respectively, for printing and mailing costs.

For the fiscal year ended March 31, 1995, the S&P Index Portfolio and the Bond
Index Portfolio incurred distribution expenses of $201,693 and $25,212 under the
Plan or .05% of net assets, respectively, during such period.  These
expenditures included $134,725 and $14,686, respectively, for sales expenses;
$32,836 and $6,763, respectively, for printing and mailing costs; and $34,132
and $3,763, respectively, for costs associated with registration fees.

The distribution-related services that may be provided under the Plans include
establishing and maintaining customer accounts and records; aggregating and
processing purchase and redemption orders with the Distributor; automatically
investing customer account cash balances; providing periodic statements to
customers; arranging for wires; answering customer inquiries concerning their
investments; assisting customers in changing dividend options, account
designations and addresses; performing sub-accounting functions; processing
dividend payments from the Trust on behalf of customers; and forwarding
shareholder communications from the Trust (such as proxies, shareholder reports,
and dividend distribution and tax notices) to these customers with respect to
investments in the trust.  Certain state securities laws may require those
financial institutions providing such distribution services to register as
dealers pursuant to state law.

PERFORMANCE

From time to time, a Portfolio may advertise yield. These figures will be based
on historical earnings and are not intended to indicate future performance. The
yield of a Portfolio refers to the annualized income generated by an investment
in such Portfolio over a specified 30-day period. The yield is calculated by
assuming that the income generated by the investment during that period is
generated over a 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.

Actual yield will depend on such variables as asset quality, average asset
maturity, the type of instruments a Portfolio invests in, changes in interest
rates on money market instruments, changes in the expenses of the Portfolio 
and other factors. For the 30-day period ending March 31, 1995, the yield for
the S&P 500 Index Portfolio was 2.69% and the yield for the Bond Index Portfolio
was 7.02%.

From time to time, the Portfolio may advertise total return. The total return of
the Portfolio 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 Portfolio 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.

For the fiscal year ended March 31, 1995, the one year total return of the S&P
500 Index Portfolio was 15.26% and the average annual total return for the past
five years and since the inception of the Portfolio was 11.13% and 13.58%,
respectively. For the fiscal year ended March 31, 1995, the one year total
return of the Bond Index Portfolio was 4.54% and the average annual total return
for the past five years and since the inception of the Portfolio was 8.07% and
7.69%, respectively.


PURCHASE AND REDEMPTION OF SHARES

The market value of portfolio securities is obtained by the Manager from an
independent pricing service. 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 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, which
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.

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

                                       12
<PAGE>
 
periods as the SEC may by order permit. The Trust also reserves the right to
suspend sales of shares of the Portfolio for any period during which the New
York Stock Exchange, the Manager, the Administrator, the Distributor and/or the
Custodians are not open for business. The New York Stock Exchange will not open
in observance of the following holidays: New Year's Day, Presidents' Day, Good
Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving and Christmas.

It is currently the Trust's policy to pay for 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 securities held by a 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 the Portfolio of the
Trust during any 90-day period of up to the lesser of $250,000 or 1% of the
Trust's net assets in cash. A gain or loss for federal income tax purposes would
be realized by a Shareholder subject to taxation upon an in-kind redemption
depending upon the Shareholder's basis in the shares of the Portfolio redeemed.


TAXES

Qualification as a RIC

The following discussion of federal income tax consequences is based on the
Internal Revenue Code of 1986, as amended (the "Code") and the regulations
issued thereunder as in effect on the date of this Statement of Additional
Information. Certain legislation proposed at the time of writing, 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 Portfolio intends to qualify as a "regulated investment company" ("RIC") as
defined under Subchapter M of the Code. By following such a policy, each of the
Portfolios expects to eliminate or reduce to a nominal amount the federal taxes
to which such Portfolio may be subject. In order to qualify for treatment as a
RIC under the Code, each Portfolio must distribute annually to its Shareholders
at least 90% of its investment company taxable income (generally, net investment
income, including net short-term capital gain) ("Distribution Requirement") and
must meet several additional requirements. Among these requirements are the
following: (i) at least 90% of the Portfolio'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 stocks or securities or
other income derived with respect to its business of investing in stocks or
securities; (ii) less than 30% of a Portfolio's gross income each taxable year
may be derived from the sale or other disposition of any of the following
investments that were held for less than three months: (a) stock or securities
(as defined in Section 2(a)(30) of the Investment Company Act); (b) options,
futures, or forward contracts (other than options, futures, or forward contracts
on foreign currencies); and (c) foreign currencies (or options, futures, or
forward contracts on foreign currencies) but only if such currencies (or
options, futures, or forward contracts) are not directly related to the
Portfolio's principal business of investing in stock or securities; (iii) at the
close of each quarter of a Portfolio'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 the Portfolio's total assets and that does not
represent more than 10% of the outstanding voting securities of the issuer; and
(iv) at the close of each quarter of the Portfolio's taxable year, not more than
25% of the value of its total 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 that the Portfolio controls or that are engaged in the
same, similar or related trades or businesses.

                                       13

Notwithstanding the Distribution Requirement described above, which only
requires each Portfolio to distribute at least 90% of its annual investment
company taxable income and does not require any minimum distribution of net
capital gain (the excess of net long-term capital gain over net short-term
capital loss), a Portfolio will be subject to a nondeductible 4% federal excise
tax to the extent it fails to distribute by the end of any calendar year 98% of
its ordinary income for that year and 98% of its capital gain net income (the
excess of short and long-term capital gains over short and long-term capital
losses) for the one-year period ending on October 31 of that year, plus certain
other amounts. 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.

Although each Portfolio intends to distribute substantially all of its net
investment income and capital gains for any taxable (i.e., fiscal) year, a
Portfolio will be subject to Federal income taxation to the extent any such
income or gains are not distributed. If, for any taxable year a Portfolio does
not qualify as a RIC, all of its taxable income will be subject to tax at
regular corporate rates without any deduction for distributions to Shareholders.
In such case, distributions (including capital gains distributions) will be
taxable as ordinary dividends to the extent of the Portfolio's current and
accumulated earnings and profits.

Tax Status of Distributions: Dividends from a Portfolio's net investment income
will be taxable to Shareholders as ordinary income (whether received in cash or
in additional shares) to the extent of the Portfolio's earnings and profits. A
portion of the dividends received from the S&P 500 Index Portfolio, not
exceeding the aggregate dividends received by the Portfolio from domestic
corporations, are eligible for the dividends-received deduction allowed to
corporations; however, dividends received by a corporate shareholder and
deducted by it pursuant to the dividends-received deduction may be subject to
the alternative minimum tax. Distributions of net capital gain will not qualify
for the dividends-received deduction and are taxable to Shareholders as 
long-term capital gain, regardless of how long Shareholders have held their
shares.

A Portfolio may either retain or distribute to Shareholders its excess of net
long-term capital gains over net short-term capital losses ("net capital
gains"). If such gains are distributed as capital gains, they are taxable to
Shareholders as long-term capital gains, regardless of the length of time the
Shareholder has held shares. Conversely, if a Portfolio elects to retain its net
capital gains, it will be taxed thereon (except to the extent of any available
capital loss carryovers) at the applicable corporate capital gains tax rate. In
this event, it is expected that a Portfolio also will elect to have shareholders
treated as having received a distribution of such gains, with the result that
they will be required to report such gains on their returns as long-term capital
gains, will receive a tax credit for their allocable share of capital gains tax
paid by the Portfolio on the gains, and will increase the tax basis for their
shares by an amount equal to the deemed distribution less the tax credit.

Ordinarily, Shareholders will include in their incomes all dividends declared by
a Portfolio in the year of payment. However, dividends declared by a Portfolio
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
Portfolio and received by the Shareholders on December 31 of the year declared
if paid by the Portfolio during the following January. The Portfolios will make
annual reports to Shareholders of the federal income tax status of all
distributions, including the amount of dividends eligible for the corporate
dividends received deduction. Generally, gains or losses on the sale or exchange
of a share will be capital gains or losses which will be long-term if the share
is held for more than one year. However, if a Shareholder realizes a loss on the
sale, exchange or redemption of a share held for six months or less and has
previously received a capital gains distribution with respect to the share (or
any undistributed net capital gains of a Portfolio with respect to such share
are included in determining the shareholder's long-term capital gains), the
shareholder must treat the loss as a long-term capital loss to the extent of the
amount of the prior capital gains distribution (or any undistributed net capital
gains of the Portfolio which have been included in determining such investor's
long-term capital gains). In addition, any loss realized on a sale

                                       14
<PAGE>
 
or other disposition of shares will be disallowed to the extent an investor
repurchases (or enters into a contract or option to repurchase) shares within a
period of 61 days (beginning 30 days before and ending 30 days after the
disposition of the shares). Investors should particularly note that this loss
disallowance rule will apply to shares received through the reinvestment of
dividends during the 61-day period.

Each Portfolio will be required in certain cases to withhold and remit to the
United States Treasury 31% of distributions payable to any Shareholder who (1)
has provided 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 report payments of interest or dividends, or (3) who has
failed to certify to the Portfolio that such Shareholder is not subject to
backup withholding.

The S&P 500 Index Portfolio may invest in stock index futures. The use of stock
index futures contracts involves specialized and complex income tax rules that
will determine the character and timing of recognition of the income received in
connection therewith by the Portfolio and thereby affect the amount and
proportion of income that will be available for distribution as dividends or
capital gain distributions.

Stock index futures contracts held by the Portfolio at the end of each taxable
year will be required to be "marked to market" for Federal income tax purposes
(that is, treated as having been sold at that time at market value). Any
unrealized gain or loss taxed pursuant to this rule will be added to realized
gains and losses recognized on other futures contracts sold by the Portfolio
during the year, and the resulting gain or loss will be deemed to consist of 
60% long-term capital gain or loss and 40% short-term capital gain or loss. The
Portfolio may elect to exclude certain hedging transactions from the 
mark-to-market rule. Gain from hedging transactions is treated as ordinary 
income.

The Trust has obtained a private letter ruling from the Internal Revenue Service
confirming that the income and assets attributable to transactions in stock
index futures contracts qualify under the above-described income and asset tests
applicable to RICs.

For purposes of the Distribution Requirement (as well as for other purposes) the
Bond Index Portfolio will be required to treat any recognized market discount on
debt obligations which it holds as interest income. Generally, market discount
is the amount by which the stated redemption price of a bond exceeds the amount
paid by a purchaser of the bond (most common where the value of a bond decreases
after original issue as a result of a decline in the creditworthiness of the
issuer or an increase in prevailing interest rates). Generally, market discount
is recognized on the disposition, or receipt of any principal payment, with
respect to a bond bearing market discount, by treating a portion of the proceeds
as interest income. The application of these rules (and the rules regarding
original issue discount) to debt obligations held by the Bond Index Portfolio
could affect (i) the amount and timing of distributions to Shareholders and (ii)
the ability of the Portfolio to satisfy the Distribution Requirement.

State Taxes

The Portfolios are not liable for any income or franchise tax in Massachusetts
if it qualifies as a RIC for Federal income tax purposes. Distributions by the
Portfolios to Shareholders and the ownership of shares may be subject to state
and local taxes.


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 Administrator is responsible for placing orders
to execute portfolio 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,

                                       15
<PAGE>
 
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 Administrator generally seeks reasonably competitive spreads
or commissions, the Trust will not necessarily be paying the lowest spread or
commission available. The Trust's policy of investing in securities with short
maturities will result in high portfolio turnover. The Trust will not purchase
portfolio securities from any affiliated person acting as principal except in
conformity with the regulations of the SEC.

The Trust does not expect to use one particular dealer, but, subject to the
Trust's policy of seeking the best net results, dealers who provide supplemental
investment research to the Administrator may receive orders for transactions by
the Trust. Information so received will be in addition to and not in lieu of the
services required to be performed by the Administrator under the Administration
Agreement, and the expenses of the Administrator will not necessarily be reduced
as a result of the receipt of such supplemental information.

The money market securities in which the Portfolios invest are traded primarily
in the over-the-counter market. Bonds and debentures are usually traded 
over-the-counter, but may be traded on an exchange. Where possible, the
Administrator will deal directly with the dealers who make a market in the
securities involved except in those circumstances where better prices and
execution are available elsewhere. Such dealers usually are acting as principal
for their own account. On occasion, securities may be purchased directly from
the issuer. Money market securities are generally traded on a net basis and do
not normally involve either brokerage commissions or transfer taxes. The cost of
executing portfolio securities transactions of the Portfolio will primarily
consist of dealer spreads and underwriting commissions.

It is expected that either of the Portfolios may execute brokerage or other
agency transactions through the Distributor, a registered broker-dealer, for a
commission, in conformity with the Investment Company Act of 1940, the
Securities Exchange Act of 1934 and the rules and regulations thereunder. Under
these provisions, the Distributor is permitted to receive and retain
compensation for effecting portfolio transactions for a Portfolio 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." 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 Administrator 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.

It is expected that the Portfolio turnover rate will normally not exceed 100%
for any Portfolio. A Portfolio turnover rate would exceed 100% if all of its
securities, exclusive of U.S. Government securities and other securities whose
maturities at the time of acquisition are one year or less, are replaced in the
period of one year. Turnover rates may vary from year to year and may be
affected by cash requirements for redemptions and by requirements which enable a
Portfolio to receive favorable tax treatment.

                                       16

The portfolio turnover rate for the S&P 500 Index Portfolio for the fiscal years
ending March 31, 1993, 1994 and 1995 were 1%, 23%, and 4%, respectively. The
portfolio turnover rate for the Bond Index Portfolio for the fiscal years ending
March 31, 1993, 1994 and 1995 were 115%, 55%, and 21%, respectively.

For the fiscal years ended March 31, 1993, 1994 and 1995, the S&P 500 Index
Portfolio paid $15,977, $27,000 and $33,285 for brokerage commissions. For the
fiscal years ended March 31, 1993, 1994 and 1995, the Bond Index Portfolio paid
no brokerage commissions.


DESCRIPTION OF SHARES

The Declaration of Trust authorizes the issuance of an unlimited number of
shares of each Portfolio, each of which represents an equal proportionate
interest in such Portfolio. Each share upon liquidation entitles a Shareholder
to a pro rata share in the net assets of the Portfolio. Shareholders have no
preemptive rights. The Declaration of Trust provides that the Trustees of the
Trust may create additional portfolios of shares or 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
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 wilful misfeasance,
bad faith, gross negligence or reckless disregard of his duties.


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.


5% SHAREHOLDERS

As of May 16, 1995, the following persons were the only persons who were record
owners (or to the knowledge of the Trust, beneficial owners) of 5% or more of
the shares of the Portfolios. The Trust believes that most of the shares
referred to above were held by the above persons in accounts for their
fiduciary, agency, or custodial customers.

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
- --------------------------------------------------------------------------------


To the Shareholders and Trustees of
 SEI Index Funds:
 
We have audited the accompanying statements of net assets of the S&P 500 Index
and Bond Index Portfolios of SEI Index Funds as of March 31, 1995, and the re-
lated statements of operations, changes in net assets and financial highlights
for the years presented. These financial statements and financial highlights
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements and financial highlights based
on our audits.
  We conducted our audits in accordance with generally accepted auditing stan-
dards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial high-
lights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as of
March 31, 1995, by correspondence with the custodian and brokers. An audit also
includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement pre-
sentation. We believe that our audits provide a reasonable basis for our opin-
ion.
  In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
S&P 500 Index and Bond Index Portfolios of SEI Index Funds as of March 31,
1995, the results of their operations, changes in their net assets and finan-
cial highlights for the years presented, in conformity with generally accepted
accounting principles.

SEI Index Funds -- March 31, 1995
 
1. ORGANIZATION:
SEI Index Funds (the "Trust") was organized as a Massachusetts business trust
under a Declaration of Trust dated March 6, 1985. The Trust is registered under
the Investment Company Act of 1940, as amended, as a diversified, open-end man-
agement investment company with two portfolios; the S&P 500 Index Portfolio and
the Bond Index Portfolio (the "Portfolios"). The assets of each Portfolio are
segregated, and a shareholder's interest is limited to the Portfolio in which
shares are held.
 
2. SIGNIFICANT ACCOUNTING POLICIES:
The following is a summary of the significant accounting policies followed by
the Portfolios.
  Security Valuation--Investments in equity securities which are traded on a
national securities exchange (or reported on the NASDAQ national market system)
are stated at the last quoted sales price if readily available for such equity
securities on each business day; other equity securities traded in the over-
the-counter market and listed equity securities for which no sale was reported
on that date are stated at the last quoted bid price. Debt obligations exceed-
ing sixty days to maturity for which market quotations are readily available
are valued at the most recently quoted bid price. Debt obligations with sixty
days or less remaining until maturity may be valued at their amortized cost.
  Federal Income Taxes--It is each Portfolio's intention to continue to qualify
as a regulated investment company for Federal income tax purposes by complying
with the appropriate provisions of the Internal Revenue Code. Accordingly, no
provisions for Federal income taxes are required in the accompanying financial
statements.
  Security Transactions and Related Income--Security transactions are accounted
for on the date the security is purchased or sold (trade date). Dividend income
is recognized on the ex-dividend date, and interest income is recognized on the
accrual basis. Costs used in determining realized gains and losses on the sales
of investment securities are those of the specific securities sold adjusted for
the accretion and amortization of purchase discounts and premiums during the
respective holding periods. Purchase discounts and premiums on securities held
by the Portfolios are accreted and amortized to maturity using a method which
approximates the effective interest method.
  Repurchase Agreements--Securities pledged as collateral for Repurchase Agree-
ments are held by the custodian bank until the respective agreements mature.
Provisions of the Repurchase Agreements and procedures adopted by the Manager
and adviser ensure that the market value of the collateral, including accrued
interest thereon, is sufficient in the event of default by the counterparty. If
the counterparty defaults and the value of the collateral declines or if the
counterparty enters into an insolvency proceeding, realization of the collat-
eral by the Portfolios may be delayed or limited.
  Futures Contracts--The S&P 500 Index Portfolio invests in S&P 500 futures
contracts. For each S&P 500 futures contract, the Portfolio pledges Treasury
bills with the broker valued at approximately $7,500 per contract. Subsequent
payments to and from the broker are made on a daily basis or upon expiration or
closing of the position, as the value of the S&P 500 Index fluctuates. These
fluctuations make the positions in the futures contracts more or less valuable,
which results in gains or losses to the Portfolio. The S&P 500 Index Portfo-
lio's investment in S&P 500 Index futures contracts is designed to assist the
Portfolio in more closely approximating the performance of the S&P 500 Index.
Risks of entering into S&P 500 Index futures contracts include the possibility
that there may be an illiquid market and that a change in the value of the con-
tract may not correlate with changes in the value of the underlying securities.
Should the S&P 500 Index move unexpectedly , the Portfolio may not receive the
anticipated benefits from the S&P 500 Index futures contracts and may realize a
loss.
  Net Asset Value Per Share--The net asset value per share of each Portfolio is
calculated on each business day. In general, it is computed by dividing the as-
sets of each Portfolio, less its liabilities, by the number of outstanding
shares of the Portfolio.
  Other--Distributions from net investment income for the Portfolios are paid
to shareholders in
 
18
<PAGE>
 
- --------------------------------------------------------------------------------
the form of monthly dividends. Any net realized capital gains on sales of secu-
rities are distributed to shareholders at least annually.
 
3. TRANSACTIONS WITH AFFILIATES:
 
The Trust and SEI Financial Management Corporation (the "Manager") are parties
to management agreements (the "Management Agreement") for the S&P 500 Index
Portfolio and Bond Index Portfolio dated July 25, 1986 and January 20, 1986,
respectively, under which the Manager provides management, administrative,
transfer agent, and shareholder services to the Portfolios for an annual fee
equal to .22% of the average daily net assets of the S&P 500 Index Portfolio
and .35% of average daily net assets of the Bond Index Portfolio. The Manager
has agreed to waive its fee so that the total annual expenses of each Portfolio
will not exceed the lower of the maximum limitations established by certain
states or voluntary expense limitations adopted by the Manager. In the event
that the total annual expenses of a Portfolio, after reflecting a waiver of all
fees by the Manager, exceed the specific limitation, the Manager has agreed to
bear such excess.
  Certain officers and/or Trustees of the Trust are also officers and/or direc-
tors of the Manager. The Trust pays each unaffiliated Trustee an annual fee for
attendance at quarterly, interim and committee meetings. Compensation of offi-
cers and affiliated Trustees is paid by the Manager.
  SEI Financial Services Company acts as the distributor (the "Distributor") of
the shares of the Portfolios under a distribution plan which provides for the
Trust to reimburse the Distributor for its distribution expenses. On an annual
basis such expenses may not exceed .05% of the Portfolios' average daily net
assets.
 
4. INVESTMENT ADVISORY AGREEMENT:
 
Under an investment advisory agreement (the "Advisory Agreement"), dated Janu-
ary 31, 1995, World Asset Management serves as the Investment Adviser of the
Portfolios and in this capacity monitors the indexing systems and determines
which securities to purchase and sell in order to keep the S&P 500 Index Port-
folio and the Bond Index Portfolio in balance with the S&P 500 Index and Lehman
Aggregate Bond Index, respectively. For its services as Investment Adviser,
World Asset Management receives a monthly fee at an annual rate of .03% of the
average daily net assets of each of the Portfolios.
  Prior to January 31, 1995, Woodbridge Capital Management, Inc. acted as in-
vestment administrator for the Trust. For its services Woodbridge was paid a
monthly fee at an annual rate of .03% of the average daily net assets of the
Portfolios. For the year ended March 31, 1995, World Asset Management and
Woodbridge Capital Management, Inc. received $21,000, and $106,000, for the S&P
500 Index Portfolio and $2,000, and $13,000, for the Bond Index Portfolio, re-
spectively.
 
5. INVESTMENT TRANSACTIONS:
 
The cost of security purchases and the proceeds from the sale of securities,
other than temporary cash investments, during the year ended March 31, 1995
were as follows:

SEI Index Funds -- March 31, 1995
 
  The Bond Index Portfolio invests primarily in securities issued or guaranteed
as to principal and interest by the U.S. Government or its agencies or instru-
mentalities. The ability of the issuers of the repurchase agreements and other
bonds held by the Portfolio to meet their obligations may be affected by eco-
nomic developments in a specific industry, state or region. The market value of
the Portfolio's investments will change in response to interest rate changes
and other factors. During periods of falling interest rates, the values of
fixed income securities generally rise. Conversely, during periods of rising
interest rates, the values of such securities generally decline. Changes by
recognized rating agencies in the ratings of any fixed income security and in
the ability of an issuer to make payments of interest and principal may also
affect the value of these investments. The following is a summary of credit
quality ratings for securities held by the Portfolio at March 31, 1995:

6. FUTURES CONTRACTS:
 
The S&P 500 Index Portfolio's investment in S&P 500 Index futures contracts is
designed to assist the Portfolio in more closely approximating the performance
of the S&P 500 Index. Risks of entering into S&P 500 Index futures contracts
include the possibility that there may be an illiquid market and that a change
in the value of the contract may not correlate with changes in the value of the
underlying securities. Should the S&P 500 Index move unexpectedly, the Portfo-
lio may not receive the anticipated benefits from the S&P 500 Index futures
contracts and may realize a loss. At March 31, 1995, open S&P 500 Index futures
contracts were as follows:
