                                     RISK/RETURN INFORMATION COMMON TO THE FUNDS

Each Fund is a mutual fund. A mutual fund pools shareholders' money and, using
professional investment managers, invests it in securities.

Each Fund has its own investment goal and strategies for reaching that goal.
Each Fund's assets are managed under the direction of its Adviser. For the S&P
500 Index Fund, SEI Investments Management Corporation (SIMC) is the Adviser,
and one or more Sub-Advisers manage a portion of the Fund's assets. SIMC acts as
"manager of managers" for the S&P 500 Index Fund, and attempts to ensure that
the Sub-Adviser(s) comply with the Fund's investment policies and guidelines.
SIMC may also recommend the appointment of additional or replacement
Sub-Advisers to the Fund's Board. Mellon Bond Associates, LLP serves as Adviser
to the Bond Index Fund.

Each Fund attempts to track the performance of a benchmark index. Factors such
as cash flows, Fund expenses, imperfect correlation between the Funds'
investments and those of their benchmarks, rounding of share prices, changes to
the benchmark, and regulatory policies may affect the Funds' ability to achieve
perfect correlation. The magnitude of any tracking error may be affected by a
higher portfolio turnover rate. Because an index is just a composite of the
prices of the securities it represents rather than an actual portfolio of those
securities, an index will have no expenses. As a result, a Fund, which will have
expenses such as brokerage, custody, management fees and other operational
costs, may not achieve its investment objective of accurately correlating to an
index. Investing in the Funds involves risk and there is no guarantee that a
Fund will achieve its goal. No matter how good a job the Advisers do, you could
lose money on your investment in the Fund, just as you could with other
investments. A Fund share is not a bank deposit and it is not insured or
guaranteed by the FDIC or any government agency.

The value of your investment in a Fund is based on the market prices of the
securities the Funds hold. These prices change daily due to economic and other
events that affect particular companies and other issuers. These price
movements, sometimes called volatility, may be greater or lesser depending on
the types of securities a Fund owns and the markets in which they trade. The
estimated level of volatility for each Fund is set forth in the Fund Summaries
that follow. The effect on a Fund of a change in the value of a single security
will depend on how widely that Fund diversifies its holdings.

                                                    securities included in the S&P 500 Index.
------------------------------------------------------------------------------------------------------
</TABLE>

INVESTMENT STRATEGY

The S&P 500 Index Fund invests substantially all of its assets in securities
listed in the S&P 500 Index, which is comprised of 500 selected securities
(mostly common stocks). The Fund's ability to replicate the performance of the
S&P 500 Index will depend to some extent on the size and timing of cash flows
into and out of the Fund, as well as on the level of the Fund's expenses. The
Sub-Adviser selects the Fund's securities under the general supervision of SIMC,
but the Sub-Adviser makes no attempt to "manage" the Fund in the traditional
sense (I.E., by using economic, market or financial analyses). Instead, the
Sub-Adviser purchases a basket of securities that includes most of the companies
in the S&P 500 Index. However, the Fund's Sub-Adviser may sell an investment if
the merit of the investment has been substantially impaired by extraordinary
events or adverse financial conditions.

WHAT ARE THE RISKS OF INVESTING IN THE FUND?

Since it purchases equity securities, the Fund is subject to the risk that stock
prices will fall over short or extended periods of time. Historically, the
equity markets have moved in cycles, and the value of the Fund's securities may
fluctuate drastically from day to day. Individual companies may report poor
results or be negatively affected by industry and/or economic trends and
developments. The prices of securities issued by such companies may suffer a
decline in response. These factors contribute to price volatility, which is the
principal risk of investing in the Fund.

The Fund is also subject to the risk that the performance of the Fund may not
correlate to that of the S&P 500 Index. In addition, the Fund is subject to the
risk that its investment approach, which attempts to replicate the performance
of the S&P 500 Index, may perform differently from other mutual funds which
focus on particular equity market segments or invest in other asset classes.

                                                    included in the Lehman Index.
------------------------------------------------------------------------------------------------------
</TABLE>

INVESTMENT STRATEGY

The Bond Index Fund invests exclusively in investment grade (I.E., BBB/Baa or
better at the time or purchase) corporate and government fixed income
securities, including mortgage-backed securities, of U.S. and foreign issuers
included in the Lehman Index. The Fund's ability to replicate the performance of
the Lehman Index will depend to some extent on the size and timing of cash flows
into and out of the Fund, as well as on the level of the Fund's expenses. The
Adviser makes no attempt to "manage" the Fund in the traditional sense (I.E., by
using economic, market or financial analyses). Instead, the Adviser will hold a
representative sample of the securities in the Lehman Index, selecting a limited
number of issues to represent entire "classes" of securities and dividing those
classes into sectors based on issuer, quality and maturity. The Adviser will
purchase various types of securities in an attempt to approximate the class and
sector weightings of the Lehman Index. The Fund's Adviser may sell a security
that has been downgraded or whose value has otherwise been impaired. The Fund in
the aggregate generally will have a dollar-weighted average duration that is
consistent with that of the Lehman Index (currently 4.5 years).

WHAT ARE THE RISKS OF INVESTING IN THE FUND?

The prices of the Fund's fixed income securities respond to economic
developments, particularly interest rate changes, as well as to perceptions
about the creditworthiness of individual issuers, including governments.
Generally, the Fund's fixed income securities will decrease in value if interest
rates rise and vice versa, and the volatility of lower rated securities is even
greater than that of higher rated securities. Also, longer-term securities are
generally more volatile, so the average maturity or duration of these securities
affects risk.

Although the Fund's U.S. government securities are considered to be among the
safest investments, they are not guaranteed against price movements due to
changing interest rates. Obligations issued by some U.S. government agencies are
backed by the U.S. Treasury, while others are backed solely by the ability of
the agency to borrow from the U.S. Treasury or by the agency's own resources.

Mortgage-backed securities are fixed income securities representing an interest
in a pool of underlying mortgage loans. Mortgage-backed securities are sensitive
to changes in interest rates, but may respond to these changes differently from
other fixed income securities due to the possibility of prepayment of the
underlying mortgage loans. As a result, it may not be possible to determine in
advance the actual maturity date or average life of a mortgage-backed security.
Rising interest rates tend to discourage refinancings, with the result that the
average life and volatility of the security will increase, exacerbating its
decrease in market price. When interest rates fall, however, mortgage-backed
securities may not gain as much in market value because of the expectation of
additional mortgage prepayments that must be reinvested at lower interest rates.
Prepayment risk may make it difficult to calculate the average maturity of the
Fund's mortgage-backed securities and, therefore, to assess the volatility risk
of the Fund.

The privately issued mortgage-backed securities that the Fund invests in are not
issued or guaranteed by the U.S. Government or its agencies or instrumentalities
and may bear a greater risk of nonpayment than securities that are backed by the
U.S. Treasury. However, the timely payment of principal and interest normally is
supported, at least partially, by various credit enhancements by banks and other
financial institutions. There can be no assurance, however, that such credit
enhancements will support full payment of the principal and interest on such
obligations. In addition, changes in the credit quality of the entity which
provides credit enhancement could cause losses to the Fund and affect its share
price.

The Fund is also subject to the risk that the performance of the Fund may not
correlate to that of the Lehman Index. Since it purchases only a small sample of
securities in the Lehman Index, the Fund's performance may not be similar to
that of the Lehman Index. In addition, the Fund is subject to the risk that its
investment approach, which attempts to replicate the performance of the Lehman
Index, may perform differently than other mutual funds which focus on particular
fixed income market segments or invest in other asset classes.

MORE INFORMATION ABOUT FUND INVESTMENTS

This prospectus describes the Funds' primary strategies, and the Funds will
normally invest at least 90% of their assets in the types of securities
described in this prospectus. However, the Funds also may invest in other
securities, use other strategies and engage in other investment practices. These
investments and strategies, as well as those described in this prospectus, are
described in detail in the Funds' Statement of Additional Information (SAI).

The investments and strategies described in this prospectus are those that the
Funds use under normal conditions. During unusual economic or market conditions,
or for temporary defensive or liquidity purposes, each Fund may invest up to
100% of its assets in cash or cash equivalents that would not ordinarily be
consistent with the Funds' objectives. A Fund will do so only if the Adviser or
Sub-Adviser believes that the risk of loss outweighs the opportunity for capital
gains or higher income. Of course, there is no guarantee that any Fund will
achieve its investment goal.

INVESTMENT ADVISERS AND SUB-ADVISER

SEI INVESTMENTS MANAGEMENT CORPORATION (SIMC) ACTS AS THE MANAGER OF MANAGERS OF
THE S&P 500 INDEX FUND, AND IS RESPONSIBLE FOR THE INVESTMENT PERFORMANCE OF THE

                                  PURCHASING, SELLING AND EXCHANGING FUND SHARES

This section tells you how to purchase, sell (sometimes called "redeem") and
exchange Class A Shares of the Funds.

The Funds offer Class A Shares only to financial institutions and intermediaries
for their own or their customers' accounts. For more information on how to open
an account and set up procedures for placing transactions, please call
1-800-DIAL-SEI.

HOW TO PURCHASE FUND SHARES

You may purchase shares on any day that the New York Stock Exchange (NYSE) is
open for business (a Business Day).

Financial institutions and intermediaries may purchase Class A Shares by placing
orders with the Funds' Transfer Agent (or its authorized agent). Institutions
and intermediaries that use certain SEI proprietary systems may place orders
electronically through those systems. Cash investments must be transmitted or
delivered in federal funds to the Funds' wire agents by the close of business on
the day after the order is placed. The Funds may reject any purchase order if it
is determined that accepting the order would not be in the best interests of the
Funds or their shareholders.

When you purchase, sell or exchange Fund shares through financial institutions
(rather than directly from the Funds), you may have to transmit your purchase,
sale and exchange requests to these financial institutions at an earlier time
for your transaction to become effective that day. This allows these financial
institutions time to process your requests and transmit them to the Funds.

Certain other intermediaries, including certain broker-dealers and shareholder
organizations, are authorized to accept purchase, redemption and exchange
request for Fund shares. These requests are normally executed at the net asset
value per share (NAV) next determined after the intermediary receives the
request. These authorized intermediaries are responsible for transmitting
requests and delivering funds on a timely basis.

If you deal directly with a financial institution or financial intermediary, you
will have to follow the institution's or intermediary's procedures for
transacting with the Funds. For more information about how to purchase, sell or
exchange Fund shares through your financial institution, you should contact your
financial institution directly. Investors may be charged a fee for purchase
and/or redemption transactions effectuated through certain broker-dealers or
other financial intermediaries.

Each Fund calculates its NAV once each Business Day at the regularly-scheduled
close of normal trading on the NYSE (normally, 4:00 p.m., Eastern time). So, for
you to receive the current Business Day's NAV, generally the Funds must receive
your purchase order before 4:00 p.m., Eastern time.

HOW THE FUNDS CALCULATE NAV

NAV for one Fund share is the value of that share's portion of the net assets of
the Fund. In calculating NAV, a Fund generally values its investment portfolio
at market price. If market prices are unavailable or a Fund thinks that they are
unreliable, fair value prices may be determined in good faith using methods
approved by the Board of Trustees.

The Bond Index Fund holds securities that are listed on foreign exchanges. These
securities may trade on weekends or other days when the Fund does not calculate
NAV. As a result, the market value of the Fund's investments may change on days
when you cannot purchase or sell Fund shares.

MINIMUM PURCHASES

To purchase Class A Shares for the first time, you must invest at least $100,000
in any Fund. Your subsequent investments in any Fund must be made in amounts of
at least $1,000. The Funds may accept investments of smaller amounts at their
discretion.

PURCHASING, SELLING AND EXCHANGING FUND SHARES

HOW TO SELL YOUR FUND SHARES

If you hold Class A Shares, you may sell your shares on any Business Day by
following the procedures established when you opened your account or accounts.
If you own shares through an account with a broker or other institution, contact
that broker or institution to sell your shares. Your financial institution or
intermediary may charge a fee for its services. The sale price of each share
will be the next NAV determined after the Funds (or their authorized
intermediary) receive your request.

RECEIVING YOUR MONEY

Normally, the Funds will make payment on your sale the Business Day after they
receive your request, but it may take up to seven days. Your proceeds will be
wired to your bank account.

REDEMPTIONS IN KIND

The Funds generally pay sale (redemption) proceeds in cash. However, under
unusual conditions that make the payment of cash unwise (and for the protection
of the Funds' remaining shareholders) the Funds might pay all or part of your
redemption proceeds in liquid securities with a market value equal to the
redemption price (redemption in kind). Although it is highly unlikely that your
shares would ever be redeemed in kind, you would probably have to pay brokerage
costs to sell the securities distributed to you, as well as taxes on any capital
gains from the sale as with any redemption.

SUSPENSION OF YOUR RIGHT TO SELL YOUR SHARES

The Funds may suspend your right to sell your shares if the NYSE restricts
trading, the SEC declares an emergency or for other reasons. More information
about this is in the SAI.

HOW TO EXCHANGE YOUR SHARES

You may exchange your Class A Shares of the Funds for Class A Shares of any
other SEI Fund on any Business Day through your financial institution or
intermediary by mail or telephone. Your financial institution or intermediary
may charge you a fee for its services. This exchange privilege may be changed or
canceled at any time upon 60 days' notice.

When you exchange shares, you are really selling your shares and buying other
Fund shares. So, your sale price and purchase price will be based on the NAV
next calculated after the Funds receive your exchange request.

TELEPHONE TRANSACTIONS

Purchasing and selling Fund shares over the telephone is extremely convenient,
but not without risk. Although the Funds have certain safeguards and procedures
to confirm the identity of callers and the authenticity of instructions, the
Funds are not responsible for any losses or costs incurred by following
telephone instructions we reasonably believe to be genuine. If you or your
financial institution transacts with the Funds over the telephone, you will
generally bear the risk of any loss.

DISTRIBUTION OF FUND SHARES

SEI Investments Distribution Co. (SIDCo.) is the distributor of the Funds.
SIDCo. receives no compensation for distributing the Funds' Class A Shares.

For Class A Shares, shareholder servicing fees, as a percentage of average daily
net assets may be up to 0.15% and 0.25%, respectively, for the S&P 500 Index and
Bond Index Funds.

                                                     DIVIDENDS AND DISTRIBUTIONS

The S&P 500 Index Fund distributes its investment income quarterly and the Bond
Index Fund distributes its investment income monthly as dividends to
shareholders. Each Fund makes distributions of capital gains, if any, at least
annually. If you own Fund shares on a Fund's record date, you will be entitled
to receive the distribution.

You will receive dividends and distributions in the form of additional Fund
shares unless you elect to receive payment in cash. To elect cash payment, you
must notify the Funds in writing prior to the date of the distribution. Your
election will be effective for dividends and distributions paid after the Funds
receive your written notice. To cancel your election, simply send the Funds
written notice.

TAXES

PLEASE CONSULT YOUR TAX ADVISER REGARDING YOUR SPECIFIC QUESTIONS ABOUT FEDERAL,
STATE AND LOCAL INCOME TAXES. Below the Funds have summarized some important tax
issues that affect the Funds and their shareholders. This summary is based on
current tax laws, which may change.

Each Fund will distribute substantially all of its net investment income and net
realized capital gains, at least annually. The dividends and distributions you
receive may be subject to federal, state and local taxation, depending upon your
tax situation. If so, they are taxable whether or not you reinvest them. Income
distributions are generally taxable at ordinary income tax rates. Capital gains
distributions are generally taxable at the rates applicable to long-term capital
gains. The Bond Index Fund generally expects that its distributions, as a result
of its investment objective, will consist of primarily ordinary income. EACH
SALE OR EXCHANGE OF FUND SHARES IS GENERALLY A TAXABLE EVENT. For tax purposes,
an exchange of your Fund share for shares of a different SEI Fund is the same as
a sale.

MORE INFORMATION ABOUT TAXES IS IN THE FUNDS' SAI.

The tables that follow present performance information about Class A Shares of
each Fund. This information is intended to help you understand each Fund's
financial performance for the past five years, or, if shorter, the period of the
Fund's operations. Some of this information reflects financial information for a
single Fund share. The total returns in the table represent the rate that you
would have earned (or lost) on an investment in a Fund, assuming you reinvested
all of your dividends and distributions.

This information has been audited by Arthur Andersen, LLP, independent public
accountants. Their report, along with each Fund's financial statements, appears
in the annual report that accompanies the Funds' Statement of Additional
Information. You can obtain the annual report, which contains more performance
information, at no charge by calling 1-800-DIAL-SEI.

                                                         RISK/RETURN INFORMATION

The Fund is a mutual fund. A mutual fund pools shareholders' money and, using
professional investment managers, invests it in securities.

The Fund has an investment goal and strategies for reaching that goal. The
Fund's assets are managed under the direction of SEI Investments Management
Corporation ("SIMC"), and one or more Sub-Advisers who manage portions of the
Fund's assets in a way that they believe will help the Fund achieve its goal.
SIMC acts as "manager of managers" for the Fund, and attempts to ensure that the
Sub-Adviser complies with the Fund's investment policies and guidelines. SIMC
may also recommend the appointment of additional or replacement Sub-Advisers to
the Fund's Board.

The Fund attempts to track the performance of a benchmark index. Factors such as
cash flows, Fund expenses, imperfect correlation between the Fund's investments
and those of their benchmarks, rounding of share prices, changes to the
benchmark, and regulatory policies may affect the Fund's ability to achieve
perfect correlation. The magnitude of any tracking error may be affected by a
higher portfolio turnover rate. Because an index is just a composite of the
prices of the securities it represents rather than an actual portfolio of those
securities, an index will have no expenses. As a result, a Fund, which will have
expenses such as brokerage, custody, management fees and other operational
costs, may not achieve its investment objective of accurately correlating to an
index. Investing in the Fund involves risk and there is no guarantee that the
Fund will achieve its goal. No matter how good a job the Adviser and Sub-Adviser
do, you could lose money on your investment in the Fund, just as you could with
other investments. A Fund share is not a bank deposit and it is not insured or
guaranteed by the FDIC or any government agency.

The value of your investment in the Fund is based on the market prices of the
securities the Fund holds. These prices change daily due to economic and other
events that affect particular companies and other issuers. These price
movements, sometimes called volatility, may be greater or lesser depending on
the types of securities the Fund owns and the markets in which they trade. The
estimated level of volatility for the Fund is set forth in the Fund Summary that
follows. The effect on the Fund of a change in the value of a single security
will depend on how widely the Fund diversifies its holdings.

                                                    securities included in the S&P 500 Index.
------------------------------------------------------------------------------------------------------
</TABLE>

INVESTMENT STRATEGY

The S&P 500 Index Fund invests substantially all of its assets in securities
listed in the S&P 500 Index, which is comprised of 500 selected securities
(mostly common stocks). The Fund's ability to replicate the performance of the
S&P 500 Index will depend to some extent on the size and timing of cash flows
into and out of the Fund, as well as on the level of the Fund's expenses. The
Sub-Adviser selects the Fund's securities under the general supervision of SIMC,
but the Sub-Adviser makes no attempt to "manage" the Fund in the traditional
sense (I.E., by using economic, market or financial analyses). Instead, the
Sub-Adviser purchases a basket of securities that includes most of the companies
in the S&P 500 Index. However, the Fund's Sub-Adviser may sell an investment if
the merit of the investment has been substantially impaired by extraordinary
events or adverse financial conditions.

WHAT ARE THE RISKS OF INVESTING IN THE FUND?

Since it purchases equity securities, the Fund is subject to the risk that stock
prices will fall over short or extended periods of time. Historically, the
equity markets have moved in cycles, and the value of the Fund's securities may
fluctuate drastically from day to day. Individual companies may report poor
results or be negatively affected by industry and/or economic trends and
developments. The prices of securities issued by such companies may suffer a
decline in response. These factors contribute to price volatility, which is the
principal risk of investing in the Fund.

The Fund is also subject to the risk that the performance of the Fund may not
correlate to that of the S&P 500 Index. In addition, the Fund is subject to the
risk that its investment approach, which attempts to replicate the performance
of the S&P 500 Index, may perform differently from other mutual funds which
focus on particular equity market segments or invest in other asset classes.

4 PROSPECTUS

MORE INFORMATION ABOUT FUND INVESTMENTS

This prospectus describes the Fund's primary strategies, and the Fund will
normally invest at least 90% of its assets in the types of securities described
in this prospectus. However, the Fund also may invest in other securities, use
other strategies and engage in other investment practices. These investments and
strategies, as well as those described in this prospectus, are described in
detail in the Fund's Statement of Additional Information (SAI).

The investments and strategies described in this prospectus are those that the
Fund uses under normal conditions. During unusual economic or market conditions,
or for temporary defensive or liquidity purposes, the Fund may invest up to 100%
of its assets in cash or cash equivalents that would not ordinarily be
consistent with the Fund's objectives. The Fund will do so only if the Adviser
or Sub-Adviser believes that the risk of loss outweighs the opportunity for
capital gains or higher income. Of course, there is no guarantee that the Fund
will achieve its investment goal.

INVESTMENT ADVISER AND SUB-ADVISER

SEI INVESTMENTS MANAGEMENT CORPORATION (SIMC) ACTS AS THE MANAGER OF MANAGERS OF
THE S&P 500 INDEX FUND, AND IS RESPONSIBLE FOR THE INVESTMENT PERFORMANCE OF THE
FUND SINCE IT ALLOCATES THE FUND'S ASSETS TO ONE OR MORE SUB-ADVISERS AND
RECOMMENDS HIRING OR CHANGING SUB-ADVISERS TO THE BOARD OF TRUSTEES. World Asset
Management, LLC, the Sub-Adviser of the S&P 500 Index Fund, makes investment
decisions for the Fund and continuously reviews, supervises and administers the
Fund's investment program.

SIMC oversees the Sub-Adviser to ensure compliance with the Fund's investment
policies and guidelines, and monitors the Sub-Adviser's adherence to its
investment style. The Board of Trustees of the Fund supervises the Adviser and
Sub-Adviser, establishes policies that they must follow in their management
activities, and oversees the hiring and termination of Sub-Advisers recommended
by SIMC. SIMC pays the Sub-Adviser out of the investment advisory fees it
receives (described below).

SIMC, an SEC-registered adviser, serves as the Adviser to the S&P 500 Index
Fund. As of May 31, 2000, SIMC had approximately $30.8 billion in assets under
management. For the fiscal year ended March 31, 2000, SIMC received advisory
fees of 0.03%.

World Asset Management, LLC ("World") serves as Sub-Adviser to the S&P 500 Index
Fund. As of May 31, 2000, World had approximately $22.3 billion in assets under
management.

                                              PURCHASING AND SELLING FUND SHARES

This section tells you how to purchase and sell (sometimes called "redeem")
Class E Shares of the Fund.

The Fund offers Class E Shares only to financial institutions and intermediaries
for their own or their customers' accounts. For more information on how to open
an account and set up procedures for placing transactions, please call
1-800-DIAL-SEI.

HOW TO PURCHASE FUND SHARES

You may purchase shares on any day that the New York Stock Exchange (NYSE) is
open for business (a Business Day).

Financial institutions and intermediaries may purchase Class E Shares by placing
orders with the Fund's Transfer Agent (or its authorized agent). Institutions
and intermediaries that use certain SEI proprietary systems may place orders
electronically through those systems. Cash investments must be transmitted or
delivered in federal funds to the Fund's wire agents by the close of business on
the day after the order is placed. The Fund may reject any purchase order if it
is determined that accepting the order would not be in the best interests of the
Fund or its shareholders.

When you purchase, sell or exchange Fund shares through financial institutions
(rather than directly from the Fund), you may have to transmit your purchase,
sale and exchange requests to these financial institutions at an earlier time
for your transaction to become effective that day. This allows these financial
institutions time to process your requests and transmit them to the Fund.

Certain other intermediaries, including certain broker-dealers and shareholder
organizations, are authorized to accept purchase, redemption and exchange
requests for Fund shares. These requests are normally executed at the net asset
value per share (NAV) next determined after the intermediary receives the
request. These authorized intermediaries are responsible for transmitting
requests and delivering funds on a timely basis.

If you deal directly with a financial institution or financial intermediary, you
will have to follow the institution's or intermediary's procedures for
transacting with the Fund. For more information about how to purchase, sell or
exchange Fund shares through your financial institution, you should contact your
financial institution directly. Investors may be charged a fee for purchase
and/or redemption transactions effectuated through certain broker-dealers or
other financial intermediaries.

The Fund calculates its NAV once each Business Day at the regularly-scheduled
close of normal trading on the NYSE (normally, 4:00 p.m., Eastern time). So, for
you to receive the current Business Day's NAV, generally the Fund must receive
your purchase order before 4:00 p.m., Eastern time.

HOW THE FUND CALCULATES NAV

NAV for one Fund share is the value of that share's portion of the net assets of
the Fund. In calculating NAV, the Fund generally values its investment portfolio
at market price. If market prices are unavailable or the Fund thinks that they
are unreliable, fair value prices may be determined in good faith using methods
approved by the Board of Trustees.

MINIMUM PURCHASES

To purchase shares for the first time, you must invest at least $5,000,000 in
the Fund. Your subsequent investments in the Fund must be made in amounts of at
least $1,000. The Fund may accept investments of smaller amounts at its
discretion.

HOW TO SELL YOUR FUND SHARES

If you hold Class E Shares, you may sell your shares on any Business Day by
following the procedures established when you opened your account or accounts.
If you own shares through an account with a broker or other institution, contact
that broker or institution to sell your shares. Your financial institution or
intermediary may charge a fee for its services. The sale price of each share
will be the next NAV determined after the Fund (or its authorized intermediary)
receives your request.
<PAGE>
6 PROSPECTUS

PURCHASING AND SELLING FUND SHARES

RECEIVING YOUR MONEY

Normally, the Fund will make payment on your sale the Business Day after the
Fund receives your request, but it may take up to seven days. Your proceeds will
be wired to your bank account.

REDEMPTIONS IN KIND

The Fund generally pays sale (redemption) proceeds in cash. However, under
unusual conditions that make the payment of cash unwise (and for the protection
of the Fund's remaining shareholders) the Fund might pay all or part of your
redemption proceeds in liquid securities with a market value equal to the
redemption price (redemption in kind). Although it is highly unlikely that your
shares would ever be redeemed in kind, you would probably have to pay brokerage
costs to sell the securities distributed to you, as well as taxes on any capital
gains from the sale as with any redemption.

SUSPENSION OF YOUR RIGHT TO SELL YOUR SHARES

The Fund may suspend your right to sell your shares if the NYSE restricts
trading, the SEC declares an emergency or for other reasons. More information
about this is in the SAI.

TELEPHONE TRANSACTIONS

Purchasing and selling Fund shares over the telephone is extremely convenient,
but not without risk. Although the Fund has certain safeguards and procedures to
confirm the identity of callers and the authenticity of instructions, the Fund
is not responsible for any losses or costs incurred by following telephone
instructions the Fund reasonably believes to be genuine. If you or your
financial institution transacts with the Fund over the telephone, you will
generally bear the risk of any loss.

DISTRIBUTION OF FUND SHARES

SEI Investments Distribution Co. (SIDCo.) is the distributor of the shares of
the Fund. SIDCo. receives no compensation for distributing the Fund's Class E
Shares.

For Class E Shares, shareholder servicing fees, as a percentage of average daily
net assets, may be up to .25%.

                                                                    PROSPECTUS 7

                                                     DIVIDENDS AND DISTRIBUTIONS

The Fund distributes its investment income periodically (at least annually) as a
dividend to shareholders. The Fund makes distributions of capital gains, if any,
at least annually. If you own Fund shares on a Fund's record date, you will be
entitled to receive the distribution.

You will receive dividends and distributions in the form of additional Fund
shares unless you elect to receive payment in cash. To elect cash payment, you
must notify the Fund in writing prior to the date of the distribution. Your
election will be effective for dividends and distributions paid after the Fund
receives your written notice. To cancel your election, simply send the Fund
written notice.

TAXES

PLEASE CONSULT YOUR TAX ADVISER REGARDING YOUR SPECIFIC QUESTIONS ABOUT FEDERAL,
STATE AND LOCAL INCOME TAXES. Below the Fund has summarized some important tax
issues that affect the Fund and its shareholders. This summary is based on
current tax laws, which may change.

The Fund will distribute substantially all of its net investment income and net
realized capital gains, at least annually. The dividends and distributions you
receive may be subject to federal, state and local taxation, depending upon your
tax situation. If so, they are taxable whether or not you reinvest them. Income
distributions are generally taxable at ordinary income tax rates. Capital gains
distributions are generally taxable at the rates applicable to long-term capital
gains. EACH SALE OF FUND SHARES IS GENERALLY A TAXABLE EVENT.

MORE INFORMATION ABOUT TAXES IS IN THE FUND'S SAI.

The table that follows presents performance information about Class E Shares of
the Fund. This information is intended to help you understand the Fund's
financial performance for the past five years, or, if shorter, the period of the
Fund's operations. Some of this information reflects financial information for a
single Fund share. The total returns in the table represent the rate that you
would have earned (or lost) on an investment in the Fund, assuming you
reinvested all of your dividends and distributions.

This information has been audited by Arthur Andersen, LLP, independent public
accountants. Their report, along with the Fund's financial statements, appears
in the annual report that accompanies the Fund's Statement of Additional
Information. You can obtain the annual report, which contains more performance

                                   THE TRUST

    SEI Index Funds (the "Trust") is a diversified, open-end management
investment company established as a Massachusetts business trust pursuant to 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 Fund pertaining to shareholder service plans, each
share of each fund represents an equal proportionate interest in that fund with
each other share of that fund. This Statement of Additional Information relates
to the Trust's S&P 500 Index Fund and the Bond Index Fund (the "Funds").

    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.

    The S&P 500 Index Fund is not sponsored, endorsed, sold or promoted by
Standard & Poor's Corporation ("S&P"). S&P makes no representation or warranty,
express or implied, to the purchasers of the Fund or any member of the public
regarding the advisability of investing in index funds or the Fund or the
ability of the S&P 500 Composite Stock Price Index (the "S&P 500 Index") 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 Fund. S&P has no obligation to take the needs of
the licensee or the owners of the Fund into consideration in determining,
composing or calculating the S&P 500 Index. S&P is not responsible for and has
not participated in the determination of, the timing of, prices at, or
quantities of the Fund to be issued or in the determination or calculation of
the equation by which the Fund is to be converted into cash. S&P has no
obligation or liability in connection with the administration, marketing or
trading of the Fund.

    S&P DOES NOT GUARANTEE THE ACCURACY AND/OR THE COMPLETENESS OF THE S&P 500
INDEX OR ANY DATA INCLUDED THEREIN. S&P MAKES NO WARRANTY, EXPRESS OR IMPLIED,
AS TO RESULTS TO BE OBTAINED BY THE FUND, OWNERS OF THE FUND, OR ANY OTHER
PERSON OR ENTITY FROM THE USE OF THE S&P 500 INDEX OR ANY DATA INCLUDED THEREIN
IN CONNECTION WITH THE RIGHTS LICENSED HEREUNDER OR FOR ANY OTHER USE. S&P MAKES
NO EXPRESS OR IMPLIED WARRANTIES, AND HEREBY DISCLAIMS ALL WARRANTIES OF
MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE OR USE WITH RESPECT TO THE
S&P 500 INDEX OR ANY DATA INCLUDED THEREIN. WITHOUT LIMITING ANY OF THE
FOREGOING, IN NO EVENT SHALL S&P HAVE ANY LIABILITY FOR ANY SPECIAL, PUNITIVE,
INDIRECT, OR CONSEQUENTIAL DAMAGES (INCLUDING LOST PROFITS), EVEN IF NOTIFIED OF
THE POSSIBILITY OF SUCH DAMAGES.

                       INVESTMENT OBJECTIVES AND POLICIES

    S&P 500 INDEX FUND--The S&P 500 Index Fund seeks to provide investment
results that correspond to the aggregate price and dividend performance of the
securities in the S&P 500 Index, which is comprised of 500 selected securities
(most of which are common stocks listed on the New York Stock Exchange).

    The Fund's ability to duplicate the performance of the S&P 500 Index will
depend to some extent on the size and timing of cashflows into and out of the
Fund, as well as on the level of the Fund's expenses.

    Adjustments made to accommodate cash flows will track the S&P 500 Index to
the maximum extent possible, and may result in brokerage expenses for the Fund.
Over time, the correlation between the

                                      S-2
<PAGE>
performance of the Fund 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 Fund, including the value of its dividend and
capital gains distributions, increased or decreased in exact proportion to
changes in the S&P 500 Index.

    The Fund will normally be invested in all of the stocks and other securities
which comprise the S&P 500 Index, except when changes are made to the S&P 500
Index itself. The Fund's policy is to be fully invested in common stocks and
other securities included in the S&P 500 Index, and it is expected that cash
reserve items would normally be less than 10% of net assets. Accordingly, an
investment in shares of the Fund involves risks similar to those of investing in
a portfolio consisting of the common stocks and other securities of some or all
of the companies included in the S&P 500 Index.

    The weightings of securities in the S&P 500 Index are based on each
security'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 stocks 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, LLC ("World"), the Fund's investment sub-adviser,
makes no attempt to "manage" the Fund in the traditional sense (I.E., by using
economic, financial or market analyses). The adverse financial situation of a
company usually will not result in the elimination of a security from the Fund.
However, an investment may be removed from the Fund if, in the judgment of
World, the merit of the investment has been substantially impaired by
extraordinary events or adverse financial conditions. Furthermore,
administrative adjustments may be made in the Fund 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 fund securities or whether to
tender fund securities pursuant to a tender or exchange offer.

    The equity securities in which the Fund invests are common stocks, preferred
stocks, securities convertible into common stock and American Depositary
Receipts ("ADRs"). The Fund may also purchase shares of real estate investment
trusts ("REITs").

    The Fund may enter into stock index futures contracts to maintain adequate
liquidity to meet its redemption demands while maximizing the level of the
Fund's assets which are tracking the performance of the S&P 500 Index, provided
that the value of these contracts does not exceed 20% of the Fund's total
assets. The Fund may only purchase those stock index futures contracts--such as
futures contracts on the S&P 500 Index--that are likely to closely replicate the
performance of the S&P 500 Index. The Fund also can sell such futures contracts
in order to close out a previously established position. The Fund 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 Fund 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.

    BOND INDEX FUND--The Bond Index Fund currently seeks to provide investment
results that correspond to the aggregate price and interest performance of the
Lehman Aggregate Bond Index (the "Lehman Index"), which tracks the performance
of debt securities. The Lehman Index is made up of the Government/Corporate
Index, the Mortgage-Backed Securities Index and the Asset-Backed Securities
Index. The Lehman Index includes fixed rate debt issues rated investment grade
or higher by one or more nationally recognized statistical ratings organizations
("NRSROs"). All issues have at least one year to maturity and an outstanding par
value of at least $100 million. Lehman Brothers, Inc. is neither a sponsor

                                      S-3
<PAGE>
of nor in any other way affiliated with the Trust. Inclusion of a security in
the Lehman Index in no way implies an opinion of Lehman Brothers, Inc. as to its
attractiveness or appropriateness as an investment.

    In seeking to generate results that correspond to the performance of the
Lehman Index, the Fund will invest in the following obligations: (i) debt
obligations issued or guaranteed by the U.S. Government or its agencies or
instrumentalities; (ii) investment-grade debt obligations issued by U.S.
corporations; (iii) debt obligations issued or guaranteed by foreign sovereign
governments, municipalities, governmental agencies or international agencies;
(iv) mortgage-backed securities, including conventional 15- and 30-year fixed
rate mortgages, graduated payment mortgages, balloon mortgages and adjustable
rate mortgages; (v) asset-backed securities; and (vi) any other issues that are
included in the Lehman Index.

    Fixed income securities in which the Fund may invest must be rated BBB or
better by S&P or Baa or better by Moody's at the time of purchase. Debt
securities rated BBB or Baa lack outstanding investment characteristics and have
speculative characteristics as well. In the event that a security held by the
Fund is downgraded below investment grade, the adviser will promptly review the
situation and take appropriate action.

    If an obligation which is included in the Lehman Index on the first day of
the month ceases to meet any of the qualifications for inclusion in the Lehman
Index during that month, the obligation remains in the Lehman Index through the
end of that month and then is eliminated from the Lehman Index. Mellon Bond
Associates, LLP ("MBA"), the Fund's investment adviser, will monitor portfolio
securities in order to determine whether any of these obligations have ceased to
qualify for inclusion in the Lehman Index. If an obligation has ceased to
qualify for inclusion in the Lehman Index as a result of: (i) a lowered
investment rating, (ii) an aggregate outstanding principal amount of less than
$100 million, or (iii) a remaining maturity that no longer exceeds one year
(collectively, "Ineligible Obligations"), the investment adviser may either
undertake to sell such Ineligible Obligations as quickly as is financially
prudent, which may be prior to or later than the time that obligation is removed
from the Lehman Index, or may determine to retain the security. To the extent
that the investment adviser determines to retain Ineligible Obligations, such
Ineligible Obligations, together with cash and money market instruments, will
not exceed 20% of the Fund's net assets. Although the Fund retains the right to
invest up to 20% of its net assets in Ineligible Obligations, cash and money
market instruments, these items are expected to constitute less than 10% of the
net assets of the Fund. Obligations held by the Fund that became Ineligible
Obligations as a result of being rated below investment grade (which securities
are often referred to as "junk bonds") will not constitute more than 5% of the
Fund's net assets. In addition, cash holdings will not exceed 5% of the Fund's
net assets. In addition, obligations that become eligible for inclusion in the
Lehman Index during a particular month generally will not actually be included
in the Lehman Index until the next month. However, the Fund may elect to
purchase any such obligation and deem it to be included in the Lehman Index once
it becomes eligible.

    The Fund generally will not hold all of the individual issues which comprise
the Lehman Index because of the large number of securities involved. Instead,
the Fund will hold a representative sample of the securities in the Index,
selecting issues to represent entire "classes" or types of securities in the
Lehman Index. Obligations included in the Lehman Index have been categorized by
MBA into sectors which have been organized on the basis of type of issuer, and
then further classified by quality and remaining maturities. The percentage of
the Fund's assets to be invested in the aggregate obligations included in a
particular sector of the Lehman Index will approximate, to the maximum extent
feasible, the percentage such sector represents in the Lehman Index. The Fund's
ability to duplicate the performance of the Lehman Index will depend to some
extent on the size and timing of cash flows into and out of the Portfolio, as
well as on the level of the Fund's expenses, and the capability of MBA to select
a representative sample of the securities included in the Lehman Index. To the
extent that the size of the Fund's assets limits the number of issues that the
Fund can purchase, there is more potential for deviation from the Lehman Index's
performance than at larger asset levels.

                                      S-4
<PAGE>
    The Fund may invest in restricted securities, including Rule 144A
securities, included in the Lehman Index.

GENERAL

    Each Fund may lend a portion of its assets to qualified institutions for the
purpose of realizing additional income, however neither Fund has any present
intention to lend its securities. Each Fund may invest in illiquid securities;
however, not more than 10% of the total assets of each Fund will be invested in
such instruments. The Funds may enter into forward commitments, or purchase
securities on a when-issued or delayed delivery basis.

    There can be no assurance that the Funds will achieve their respective
investment objectives.

             DESCRIPTION OF PERMITTED INVESTMENTS AND RISK FACTORS

    AMERICAN DEPOSITARY RECEIPTS ("ADRs")--ADRs are securities, typically issued
by a U.S. financial institution (a "depositary"), that evidence ownership
interests in a security or a pool of securities issued by a foreign issuer and
deposited with the depositary. ADRs may be available through "sponsored" or
"unsponsored" facilities. A sponsored facility is established jointly by the
issuer of the security underlying the receipt and a depositary, whereas an
unsponsored facility may be established by a depositary without participation by
the issuer of the receipts underlying security. Holders of unsponsored
depositary receipts generally bear all the costs of the unsponsored facility.
The depositary of an unsponsored facility frequently is under no obligation to
distribute shareholder communications received from the issuer of the deposited
security or to pass through, to the holders of the receipts, voting rights with
respect to the deposited securities.

    ASSET-BACKED SECURITIES (NON-MORTGAGE)--Asset-backed securities consist of
securities secured by company receivables, truck and auto loans, leases and
credit card receivables. Such securities are generally issued as pass-through
certificates, which represent undivided fractional ownership interests in the
underlying pools of assets. Such securities also may be debt instruments, which
are also known as collateralized obligations and are generally issued as the
debt of a special purpose entity, such as a trust or corporation, organized
solely for purpose of owning such assets and issuing such debt. A Fund may
invest in other asset-backed securities that may be created in the future if the
Advisor determines they are suitable.

    BANK OBLIGATIONS--The Funds may invest in bank obligations of U.S.
commercial banks or savings and loan institutions, including 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. A certificate of deposit is an interest-bearing instrument with a
specific maturity issued by a bank or savings and loan institution in exchange
for the deposit of funds that normally can be traded in the secondary market
prior to maturity.

    EQUITY SECURITIES--Equity securities represent ownership interests in a
company or corporation, and include common stock, preferred stock, and warrants
and other rights to acquire such instruments. Investments in equity securities
are subject to 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 provisions.
Fluctuations in the value of equity securities will not necessarily affect cash
income derived from these securities, but will affect a Fund's net asset value.

    FIXED INCOME SECURITIES--Fixed income securities are debt obligations issued
by corporations, municipalities and other borrowers. While securities with
longer maturities tend to produce higher yields,

                                      S-5
<PAGE>
the prices of longer maturity securities are also subject to greater market
fluctuations. The market value of the fixed income investments will generally
change in response to interest rate changes and other factors. During periods of
falling interest rates, the values of outstanding fixed income securities
generally rise. Conversely, during periods of rising interest rates, the values
of such securities generally decline.

    Changes by recognized agencies in the rating of any fixed income security
and in the ability of an issuer to make payments of interest and principal also
affect the value of these investments. Changes in the value of these securities
will not necessarily affect cash income derived from these securities but will
affect a Fund's net asset value.

    FOREIGN SECURITIES--Foreign securities are securities issued by non-U.S.
issuers. The Funds may invest in U.S. dollar denominated obligations or
securities of foreign issuers. Permissible investments may consist of
obligations of foreign branches of U.S. banks and foreign banks, including
European Certificates of Deposit, European Time Deposits, Canadian Time
Deposits, Yankee Certificates of Deposit and investments in Canadian Commercial
Paper and Europaper. These instruments may subject a Fund to investment risks
that differ in some respects from those related to investments in obligations of
U.S. domestic issuers. Investing in the securities of foreign companies and the
utilization of forward foreign currency contracts involve special risks and
considerations not typically associated with investing in U.S. companies. Such
risks include future adverse political and economic developments, the possible
imposition of withholding taxes on interest or other income, possible seizure,
nationalization, or expropriation of foreign deposits, the possible
establishment of exchange controls or taxation at the source, greater
fluctuations in value due to changes in the exchange rates, or the adoption of
other foreign governmental restrictions which might adversely affect the payment
of principal and interest on such obligations. Such investments may also entail
higher custodial fees and sales commissions than domestic investments. Foreign
issuers of securities or obligations are often subject to different accounting
treatment and engage in business practices different from those respecting
domestic issuers of similar securities or obligations. Foreign branches of U.S.
banks and foreign banks may be subject to less stringent reserve requirements
than those applicable to domestic branches of U.S. banks. The yankee obligations
selected for a Fund will adhere to the same quality standards as those utilized
for the selection of domestic debt obligations.

    Some securities issued by foreign governments or their subdivisions,
agencies or instrumentalities may not be backed by the full faith and credit of
the foreign government.

    FUTURES AND OPTIONS ON FUTURES--Futures contracts provide for the future
sale by one party and purchase by another party of a specified amount of a
specific security at a specified future time and at a specified price. An option
on a futures contract gives the purchaser the right, in exchange for a premium,
to assume a position in a futures contract at a specified exercise price during
the term of the option. A Fund may use futures contracts and related options for
BONA FIDE hedging purposes, to offset changes in the value of securities held or
expected to be acquired or be disposed of, to minimize fluctuations in foreign
currencies, or to gain exposure to a particular market or instrument. A Fund
will minimize the risk that it will be unable to close out a futures contract by
only entering into futures contracts that are traded on national futures
exchanges.

    An index futures contract is a bilateral agreement 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 bond index value at the close of
trading of the contract and the price at which the futures contract is
originally struck. No physical delivery of the bonds comprising the index is
made; generally contracts are closed out prior to the expiration date of the
contract.

    In order to avoid leveraging and related risks, when a Fund invests in
futures contracts, it will cover its position by depositing an amount of cash or
liquid securities equal to the market value of the futures positions held, less
margin deposits, in a segregated account and that amount will be marked to
market on a daily basis.

                                      S-6
<PAGE>
    A Fund may enter into futures contracts and options on futures contracts
traded on an exchange regulated by the Commodities Futures Trading Commission
("CFTC"), so long as, to the extent that such transactions are not for "bona
fide hedging purposes," the aggregate initial margin and premiums on such
positions (excluding the amount by which such options are in the money) do not
exceed 5% of the Fund's net assets.

    There are risks associated with these activities, including the following:
(1) the success of a hedging strategy may depend on an ability to predict
movements in the prices of individual securities, fluctuations in markets and
movements in interest rates, (2) there may be an imperfect or no correlation
between the changes in market value of the securities held by the Fund and the
prices of futures and options on futures, (3) there may not be a liquid
secondary market for a futures contract or option, (4) trading restrictions or
limitations may be imposed by an exchange, and (5) government regulations may
restrict trading in futures contracts and options on futures. In addition, some
strategies reduce a Fund's exposure to price fluctuations, while others tend to
increase its market exposure. Futures and options on futures can be volatile
instruments and involve certain risks that could negatively impact a Fund's
return.

    ILLIQUID SECURITIES--Illiquid securities are securities that cannot be
disposed of within seven business days at approximately the price at which they
are being carried on the Fund's books. Illiquid securities include demand
instruments with demand notice periods exceeding seven days, securities for
which there is no active secondary market, and repurchase agreements with
maturities over seven days in length.

    JUNK BONDS--Bonds rated below investment grade are often referred to as
"junk bonds." Such securities involve greater risk of default or price declines
than investment grade securities due to changes in the issuer's creditworthiness
and the outlook for economic growth. The market for these securities may be less
active, causing market price volatility and limited liquidity in the secondary
market. This may limit a Fund's ability to sell such securities at their market
value. In addition, the market for these securities may also be adversely
affected by legislative and regulatory developments. Credit quality in the junk
bond market can change suddenly and unexpectedly, and even recently issued
credit ratings may not fully reflect the actual risks imposed by a particular
security.

    MONEY MARKET INSTRUMENTS--Money market instruments are high-quality,
dollar-denominated, short-term debt instruments. They consist of: (i) bankers'
acceptances, certificates of deposits, notes and time deposits of highly-rated
U.S. banks and U.S. branches of foreign banks; (ii) U.S. Treasury obligations
and obligations issued by the agencies and instrumentalities of the U.S.
Government; (iii) high-quality commercial paper issued by U.S. and foreign
corporations; (iv) debt obligations with a maturity of one year or less issued
by corporations that issue high-quality commercial paper; and (v) repurchase
agreements involving any of the foregoing obligations entered into with
highly-rated banks and broker-dealers.

    MORTGAGE BACKED SECURITIES--Mortgage-backed securities are instruments that
entitle the holder to a share of all interest and principal payments from
mortgages underlying the security. The mortgages backing these securities
include conventional fifteen- and thirty-year fixed-rate mortgages, graduated
payment mortgages, adjustable rate mortgages and balloon mortgages. During
periods of declining interest rates, prepayment of mortgages underlying
mortgage-backed securities can be expected to accelerate. Prepayment of
mortgages which underlie securities purchased at a premium often results in
capital losses, while prepayment of mortgages purchased at a discount often
results in capital gains. Because of these unpredictable prepayment
characteristics, it is often not possible to predict accurately the average life
or realized yield of a particular issue.

    The Bond Index Fund may purchase securities representing interests in
mortgage pools guaranteed by U.S. Government agencies or instrumentalities,
including Government National Mortgage Association ("GNMA"), Fannie Mae and
Federal Home Loan Mortgage Corporation ("FHLMC"), conventional mortgage-pass
through obligations, and Federal Housing Administration-insured mortgage pools.

                                      S-7

    GOVERNMENT PASS-THROUGH SECURITIES--These are securities that are issued or
guaranteed by a U.S. Government agency representing an interest in a pool of
mortgage loans. The primary issuers or guarantors of these mortgage-backed
securities are GNMA, Fannie Mae and FHLMC. 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 Fund will receive monthly scheduled payments of principal and
interest. In addition, the Fund may receive unscheduled principal payments
representing prepayments on the underlying mortgages. Any prepayments will be
reinvested at the then prevailing interest rate.

    Mortgage-backed securities issued by Fannie Mae include Fannie Mae
Guaranteed Mortgage Pass-Through Certificates (also known as "Fannie Maes") that
are solely the obligations of Fannie Mae and are not backed by or entitled to
the full faith and credit of the United States. Fannie Mae is a government-
sponsored organization owned entirely by private stockholders. Fannie Maes are
guaranteed as to timely payment of the principal and interest by Fannie Mae.
Mortgage-backed securities issued by the FHLMC include FHLMC Mortgage
Participation Certificates (also known as "Freddie Macs" or "PC's"). The FHLMC
is a corporate instrumentality of the United States, created pursuant to an Act
of Congress, which is owned entirely by Federal Home Loan Banks. Freddie Macs
are not guaranteed by the United States or by any Federal Home Loan Banks and do
not constitute a debt or obligation of the United States or of any Federal Home
Loan Bank. Freddie Macs entitle the holder to timely payment of interest, which
is guaranteed by the FHLMC. The FHLMC guarantees either ultimate collection or
timely payment of all principal payments on the underlying mortgage loans. When
the FHLMC does not guarantee timely payment of principal, FHLMC may remit the
amount due on account of its guarantee of ultimate payment of principal at any
time after default on an underlying mortgage, but in no event later than one
year after it becomes payable.

PRIVATE PASS-THROUGH SECURITIES--These are mortgage-backed securities issued by
a non-governmental entity, such as a trust or corporate entity. These securities
include collateralized mortgage obligations ("CMOs") and real estate mortgage
investment conduits ("REMICs"). While they are generally structured with one or
more types of credit enhancement, private pass-through securities typically lack
a guarantee by an entity having the credit status of a governmental agency or
instrumentality.

COLLATERALIZED MORTGAGE OBLIGATIONS ("CMOs")--CMOs are debt obligations or
multiclass pass-through certificates issued by agencies or instrumentalities of
the U.S. Government or by private originators or investors in mortgage loans.
Principal payments on the underlying mortgage assets may cause CMOs to be
retired substantially earlier then their stated maturities or final distribution
dates, resulting in a loss of all or part of any premium paid. In a CMO, series
of bonds or certificates are usually issued in multiple classes. Principal and
interest paid on the underlying mortgage assets may be allocated among the
several classes of a series of a CMO in a variety of ways. Each class of a CMO,
often referred to as a "tranche," is issued with a specific fixed or floating
coupon rate and has a stated maturity or final distribution date.

REMICs--A REMIC is a CMO that qualifies for special tax treatment under the
Internal Revenue Code of 1986, as amended, (the "Code") and invests in certain
mortgages principally secured by interests in real property. Investors may
purchase beneficial interests in REMICs, which are known as "regular" interests,
or "residual" interests. Guaranteed REMIC pass-through certificates ("REMIC
Certificates") issued by Fannie Mae or FHLMC represent beneficial ownership
interests in a REMIC trust consisting principally of

                                      S-8
<PAGE>
mortgage loans or Fannie Mae, FHLMC or GNMA-guaranteed mortgage pass-through
certificates. For FHLMC REMIC Certificates, FHLMC guarantees the timely payment
of interest and also guarantees the payment of principal as payments are
required to be made on the underlying mortgage participation certificates.

STRIPPED MORTGAGE-BACKED SECURITIES ("SMBs")--SMBs are usually structured with
two classes that receive specified proportions of the monthly interest and
principal payments from a pool of mortgage securities. One class may receive all
of the interest payments and is thus termed an interest-only class ("IO"), while
the other class may receive all of the principal payments and is thus termed the
principal-only class ("PO"). The value of IOs tends to increase as rates rise
and decrease as rates fall; the opposite is true of POs. During times when
interest rates are experiencing fluctuations, such securities can be difficult
to price on a consistent basis. The market for SMBs is not as fully developed as
other markets; SMBs, therefore, may be illiquid.

    OPTIONS--A Fund may purchase and write put and call options on indices and
enter into related closing transactions. A put option on a security gives the
purchaser of the option the right to sell, and the writer of the option the
obligation to buy, the underlying security at any time during the option period.
A call option on a security gives the purchaser of the option the right to buy,
and the writer of the option the obligation to sell, the underlying security at
any time during the option period. The premium paid to the writer is the
consideration for undertaking the obligations under the option contract.

    A Fund may purchase and write put and call options on foreign currencies
(traded on U.S. and foreign exchanges or over-the-counter markets) to manage its
exposure to exchange rates. Call options on foreign currency written by a Fund
will be "covered," which means that the Fund will own an equal amount of the
underlying foreign currency.

    Put and call options on indices are similar to options on securities except
that options on an index give the holder the right to receive, upon exercise of
the option, an amount of cash if the closing level of the underlying index is
greater than (or less than, in the case of puts) the exercise price of the
option. This amount of cash is equal to the difference between the closing price
of the index and the exercise price of the option, expressed in dollars
multiplied by a specified number. Thus, unlike options on individual securities,
all settlements are in cash, and gain or loss depends on price movements in the
particular market represented by the index generally, rather than the price
movements in individual securities.

    All options written on indices or securities must be covered. When a Fund
writes an option or security on an index or a foreign currency, it will
establish a segregated account containing cash or liquid securities in an amount
at least equal to the market value of the option and will maintain the account
while the option is open or will otherwise cover the transaction.

    Each Fund may trade put and call options on securities and securities
indices, as the advisers determine is appropriate in seeking the Fund's
investment objective, and except as restricted by each Fund's investment
limitations as set forth below. See "Investment Limitations."

    The initial purchase (sale) of an option contract is an "opening
transaction." In order to close out an option position, a Fund may enter into a
"closing transaction," which is simply the sale (purchase) of an option contract
on the same security with the same exercise price and expiration date as the
option contract originally opened. If a Fund is unable to effect a closing
purchase transaction with respect to an option it has written, it will not be
able to sell the underlying security until the option expires or the Fund
delivers the security upon exercise.

    A Fund may purchase put and call options on securities to protect against a
decline in the market value of the securities in its portfolio or to anticipate
an increase in the market value of securities that the Fund may seek to purchase
in the future. A Fund purchasing put and call options pays a premium therefor.
If price movements in the underlying securities are such that exercise of the
options would not be

                                      S-9
<PAGE>
profitable for the Fund loss of the premium paid may be offset by an increase in
the value of the Fund's securities or by a decrease in the cost of acquisition
of securities by the Fund.

    A Fund may write covered call options on securities as a means of increasing
the yield on its assets and as a means of providing limited protection against
decreases in its market value. When a Fund writes an option, if the underlying
securities do not increase or decrease to a price level that would make the
exercise of the option profitable to the holder thereof, the option generally
will expire without being exercised and the Fund will realize as profit the
premium received for such option. When a call option of which a Fund is the
writer is exercised, the Fund will be required to sell the underlying securities
to the option holder at the strike price, and will not participate in any
increase in the price of such securities above the strike price. When a put
option of which a Fund is the writer is exercised, the Fund will be required to
purchase the underlying securities at a price in excess of the market value of
such securities.

    A Fund may purchase and write options on an exchange or over-the-counter.
Over-the-counter options ("OTC options") differ from exchange-traded options in
several respects. They are transacted directly with dealers and not with a
clearing corporation, and therefore entail the risk of non-performance by the
dealer. OTC options are available for a greater variety of securities and for a
wider range of expiration dates and exercise prices than are available for
exchange-traded options. Because OTC options are not traded on an exchange,
pricing is done normally by reference to information from a market maker. It is
the position of the Securities and Exchange Commission (the "SEC") that OTC
options are generally illiquid.

    The market value of an option generally reflects the market price of an
underlying security. Other principal factors affecting market value include
supply and demand, interest rates, the pricing volatility of the underlying
security and the time remaining until the expiration date.

RISK FACTORS.  Risks associated with options transactions include: (1) the
success of a hedging strategy may depend on an ability to predict movements in
the prices of individual securities, fluctuations in markets and movements in
interest rates; (2) there may be an imperfect correlation between the movement
in prices of options and the securities underlying them; (3) there may not be a
liquid secondary market for options; and (4) while a Fund will receive a premium
when it writes covered call options, it may not participate fully in a rise in
the market value of the underlying security.

    REAL ESTATE INVESTMENT TRUST ("REITs")--REITs are trusts that invest
primarily in commercial real estate or real estate-related loans. A REIT is not
taxed on income distributed to its shareholders or unitholders if it complies
with regulatory requirements relating to its organization, ownership, assets and
income, and with a regulatory requirement that it distribute to its shareholders
or unitholders at least 95% of its taxable income for each taxable year.
Generally, REITs can be classified as Equity REITs, Mortgage REITs and Hybrid
REITs. Equity REITs invest the majority of their assets directly in real
property and derive their income primarily from rents and capital gains from
appreciation realized through property sales. Mortgage REITs invest the majority
of their assets in real estate mortgages and derive their income from interest
payments. Hybrid REITs combine the characteristics of both Equity and Mortgage
REITs. By investing in REITs indirectly through the Fund, shareholders will bear
not only the proportionate share of the expenses of the Fund, but also,
indirectly, similar expenses of underlying REITs.

    A Fund may be subject to certain risks associated with the direct
investments of the REITs. REITs may be affected by changes in the of their
underlying properties and by defaults by borrowers or tenants. Mortgage REITs
may be affected by the quality of the credit extended. Furthermore, REITs are
dependent on specialized management skills. Some REITs may have limited
diversification and may be subject to risks inherent on financing a limited
number of properties. REITs depend generally on their ability to generate cash
flow to make distributions to shareholders or unitholders, and may be subject to
defaults by borrowers and to self-liquidations. In addition, a REIT may be
affected by its failure to qualify for tax-free pass-through of income under the
Code or its failure to maintain exemption from registration under the Investment
Company Act of 1940 (the "1940 Act").

                                      S-10
<PAGE>
    REPURCHASE AGREEMENTS--Repurchase agreements are agreements under which
securities are acquired from a securities dealer or bank subject to resale on an
agreed upon date and at an agreed upon price which includes principal and
interest. A Fund bears a risk of loss in the event that the other party to a
repurchase agreement defaults on its obligations and the Fund is delayed or
prevented from exercising its rights to dispose of the collateral securities. A
fund may enter into repurchase agreements only with financial institutions that
its adviser deems to present minimal risk of bankruptcy during the term of the
agreement, based on guidelines that are periodically reviewed by the Board of
Trustees. These guidelines currently permit each Fund to enter into repurchase
agreements only with approved banks and primary securities dealers, as
recognized by the Federal Reserve Bank of New York, which have minimum net
capital of $100 million, or with a member bank of the Federal Reserve System.
Repurchase agreements are considered to be loans collateralized by the
underlying security. Repurchase agreements entered into by a Fund 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. Each adviser will monitor compliance with this
requirement. Under all repurchase agreements entered into by a Fund, the Fund or
its agent will have actual or constructive possession of the securities held as
collateral for the repurchase agreement. However, if the seller defaults, a Fund
could realize a loss on the sale of the underlying security to the extent the
proceeds of the sale are less than the resale price. In addition, even though
the Bankruptcy Code provides protection for most repurchase agreements, if the
seller should be involved in bankruptcy or insolvency proceedings, a Fund may
incur delay and costs in selling the security and may suffer a loss if the Fund
is treated as an unsecured creditor.

    SECURITIES LENDING--In order to generate additional income, a Fund may lend
its securities pursuant to agreements requiring that the loans be continuously
secured by cash, securities of the U.S. Government or its agencies, or any
combination of cash and such securities, in an amount at least equal to the
market value of the loaned securities. Loans are made only to borrowers deemed
by the advisers to be in good standing and when, in the judgment of the
advisers, the consideration that can be earned currently from such loaned
securities justifies the attendant risk. Any loan may be terminated by either
party upon reasonable notice to the other party. The Funds may use the
Distributor as a broker in these transactions.

    STOCK INDEX FUTURES--A stock index futures contract is a bilateral agreement
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 securities
comprising the index is made; generally contracts are closed out prior to the
expiration date of the contract.

    In order to avoid leveraging and related risks, when a Fund purchases
futures contracts, it will collateralize its position by depositing an amount of
cash or liquid securities equal to the market value of the futures positions
held, less margin deposits, in a segregated account. Collateral equal to the
current market value of the futures position will be marked to market on a daily
basis.

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

    The S&P 500 Index Fund may invest in stock index futures. No price is paid
upon entering into futures contracts. Instead, a Fund is 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 nature of initial and variation margin in futures
transactions is different from that of margin in security

                                      S-11
<PAGE>
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
Fund upon termination of the contract, assuming all contractual obligations have
been satisfied. 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 stock index futures position is defined as the closing
value of the index multiplied by 500 times the number of contracts held.

    The Fund's ability to effectively utilize futures contracts 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 Fund
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 Fund will not engage in transactions in futures
contracts for speculative purposes.

    TRACKING ERROR RISK--Factors such as Fund expenses, imperfect correlation
between the Fund's investments and those of their benchmarks, rounding of share
prices, changes to the benchmark, regulatory policies, and leverage, may affect
their ability to achieve perfect correlation. The magnitude of any tracking
error may be affected by a higher portfolio turnover rate. Because an index is
just a composite of the prices of the securities it represents rather than an
actual portfolio of those securities, an index will have no expenses. As a
result, a Fund which will have expenses such as taxes, custody, management fees
and other operational costs, including brokerage fees, may not achieve its
investment objective of accurately correlating to an index.

    U.S. GOVERNMENT SECURITIES--The Funds 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 U.S. Government
including, among others, Export Import Bank of the United States, Farmers Home
Administration, Federal Farm Credit Bank, Federal Housing Administration,
Maritime Administration, Small Business Administration, and The Tennessee Valley
Authority and obligations issued or guaranteed by instrumentalities of the U.S.
Government including, among others, Federal Home Loan Banks, FHLMC, Federal
Intermediate Credit Banks, Federal Land Banks, Fannie Mae and the United States
Postal Service. Some of these securities are supported by the full faith and
credit of the U.S. Treasury (E.G., GNMA securities), others are supported by the
right of the issuer to borrow from the Treasury (E.G., Federal Farm Credit Bank
securities) and still others are supported only by the credit of the
instrumentality (E.G., Fannie Mae securities). Guarantees of principal by
agencies or instrumentalities of the U.S. 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 Fund's shares.

                                      S-12
<PAGE>
    U.S. TREASURY OBLIGATIONS--U.S. Treasury obligations consist of bills, notes
and bonds issued by the U.S. Treasury, as well as separately traded interest and
principal component parts of such obligations, known as Separately Traded
Registered Interest and Principal Securities ("STRIPS") that are transferable
through the Federal book-entry system.

    VARIABLE AND FLOATING RATE INSTRUMENTS--Certain obligations may carry
variable or floating rates of interest and may involve a conditional or
unconditional demand feature. Such instruments bear interest at rates which are
not fixed, but which vary with changes in specified market rates or indices. The
interest rates on these securities may be reset daily, weekly, quarterly or at
some other interval, and may have a floor or ceiling on interest rate changes.
There is a risk that the current interest rate on such obligations may not
accurately reflect existing market interest rates. A demand instrument with a
demand notice exceeding seven days may be considered illiquid if there is no
secondary market for such security.

    WHEN-ISSUED AND DELAYED DELIVERY SECURITIES--The Bond Index Fund 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 Fund 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.

    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.

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

    YANKEE OBLIGATIONS--Yankee obligations ("Yankees") are U.S.
dollar-denominated instruments of foreign issuers who either register with the
SEC or issue under Rule 144A under the Securities Act of 1933 Act (the "1933
Act"). These obligations consist of debt securities (including preferred or
preference stock of non-governmental issuers), certificates of deposit, fixed
time deposits and bankers' acceptances issued by foreign banks, and debt
obligations of foreign governments or their subdivisions, agencies and
instrumentalities, international agencies and supranational entities. Some
securities issued by foreign governments or their subdivisions, agencies and
instrumentalities may not be backed by the full faith and credit of the foreign
government.

    The Yankee obligations selected for a Fund will adhere to the same quality
standards as those utilized for the selection of domestic debt obligations.

                             INVESTMENT LIMITATIONS

Neither Fund may:

 1. Purchase securities of any issuer (except securities issued or guaranteed by
    the U.S. Government, its agencies or instrumentalities) if, as a result,
    more than 5% of the Fund's total assets would be invested in the securities
    of such issuer. This restriction applies to 75% of each Fund's total assets.

                                      S-13
<PAGE>
 2. Purchase any securities which would cause more than 25% of the Fund's total
    assets 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 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 that Fund. 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 that Fund, and any interest
    paid on such borrowings will reduce the Fund's income.

 4. Make loans, except that each Fund (i) 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 Fund's total assets, (ii) may engage in securities
    lending as described in this Prospectus, and (iii) may purchase or hold debt
    instruments in accordance with its investment objectives and policies.

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

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

 7. Purchase or sell real estate, real estate limited partnership interests,
    physical commodities or commodities contracts. However, subject to its
    permitted investments, a Fund may purchase (i) obligations issued by
    companies which invest in real estate, commodities or commodities contracts,
    and (ii) commodities contracts related to financial instruments, such as
    financial futures contracts.

 8. 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.

 9. Act as an underwriter of securities of other issuers except as it may be
    deemed an underwriter in selling a fund security.

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

11. Issue senior securities (as defined in the 1940 Act) except in connection
    with permitted borrowings as described in the Prospectuses and this
    Statement of Additional Information or as permitted by rule, regulation or
    order of the SEC.

12. 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.

13. 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.

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

                                      S-14
<PAGE>
15. Invest in interests in oil, gas or other mineral exploration or development
    programs.

16. Purchase restricted securities (securities which must be registered under
    the 1933 Act before they may be offered or sold to the public) or other
    illiquid securities except as described in the Prospectuses and this
    Statement of Additional Information.

    The foregoing percentages and percentage limitations (except the limitation
on borrowings) 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

                      THE ADMINISTRATOR AND TRANSFER AGENT

    The management agreement ("Management Agreement") provides that the
administrator, SEI Investments Fund Management (the "Administrator"), 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 SEI Management 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 Fund, 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 1940 Act) 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 Trust, by a vote of a majority of the outstanding
shares of a Fund or by SEI Management 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 Administrator, a Delaware business trust, has its principal business
offices at Oaks, Pennsylvania 19456. SEI Investments Management Corporation
("SIMC"), a wholly-owned subsidiary of SEI Investments Company ("SEI
Investments"), is the owner of all beneficial interest in the Administrator. SEI
Investments and its subsidiaries and affiliates, including the Administrator,
are leading providers of funds evaluation services, trust accounting systems,
and brokerage and information services to financial institutions, institutional
investors, and money managers. The Administrator and its affiliates also serve
as administrator or sub-administrator to the other mutual funds including, but
without limitation: The Achievement Funds Trust, The Advisors' Inner Circle
Fund, Alpha Select Funds, Amerindo Funds, Inc., The Arbor Fund, ARK Funds,
Armada Funds, The Armada Advantage Fund, Bishop Street Funds, CNI Charter Funds,

Administrator will pay such excess. The Administrator will not be required to
bear expenses of the Fund to an extent which would result in the Fund's
inability to qualify as a regulated investment company under provisions of the
Code. The term "expenses" is defined in such laws or regulations, and generally
excludes brokerage commissions, distribution expenses, taxes, interest and
extraordinary expenses.

                          THE ADVISERS AND SUB-ADVISER

    SEI Investments Management Corporation ("SIMC") is a wholly-owned subsidiary
of SEI Investments, a financial services company. The principal business address
of SIMC and SEI Investments is Oaks, Pennsylvania, 19456. SEI Investments was
founded in 1968, and is a leading provider of investment solutions to banks,
institutional investors, investment advisers and insurance companies. Affiliates
of SIMC have provided consulting advice to institutional investors for more than
20 years, including advice regarding selection and evaluation of sub-advisers.
SIMC currently serves as manager to more than [7] investment companies,
including more than [37] funds, with more than $30.8 billion in assets under
management as of May 31, 2000.

    SIMC is the investment adviser for S&P 500 Index Fund, and operates as a
"manager of managers." As adviser to the S&P 500 Index Fund, SIMC oversees the
investment advisory services provided to the Funds and manages the cash portion
of the Fund's assets. Pursuant to a separate sub-advisory agreement with SIMC,
and under the supervision of SIMC and the Board of Trustees, World Asset
Management, LLC ("World" or the "Sub-Adviser") is responsible for the day-to-day
investment management of all or a discrete portion of the assets of the Fund.
Sub-advisers are selected for the Fund based primarily upon the research and
recommendations of SIMC, which evaluates quantitatively and qualitatively a
sub-adviser's skills and investment results in managing assets for specific
asset classes, investment styles and strategies.

    Subject to Board review, SIMC evaluates sub-adviser performance, and
oversees sub-adviser compliance with the Fund's investment objectives, policies
and restrictions. SIMC HAS ULTIMATE RESPONSIBILITY FOR THE INVESTMENT
PERFORMANCE OF THE FUND DUE TO ITS RESPONSIBILITY TO OVERSEE SUB-ADVISERS AND
RECOMMEND THEIR HIRING, TERMINATION AND REPLACEMENT.

    For its advisory services, SIMC is entitled to a fee, which is calculated
daily and paid monthly, at the annual rate of .03% of the average daily net
assets of the S&P 500 Index Fund. For the fiscal year ended March 31, 1999 and
2000, the S&P 500 Index Fund paid adviser fees of $559,476, after a fee waiver
of $0, and $773,306 after a fee waiver of $0, respectively) to SIMC.

    Mellon Bond Associates, LLP ("MBA") serves as the investment adviser to the
Bond Index Fund. MBA has been serving as the adviser to the Bond Index Fund
since October 2, 1995.

    For its advisory services, MBA is entitled to a fee, which is calculated
daily and paid monthly, at the annual rate of .07% of the average daily net
assets of the Bond Index Fund. For the fiscal years ended March 31, 1998, 1999,
and 2000, MBA received fees of $27,435, $34,116, and $44,222 respectively, from
the Bond Index Fund.

    Each investment advisory and sub-advisory agreement (each an "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.

    The continuance of each Investment Advisory Agreement must be specifically
approved at least annually (i) by the vote of a majority of the outstanding
shares of the Fund 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

                                      S-16
<PAGE>
"interested persons" of any party thereto, cast in person at a meeting called
for the purpose of voting on such approval. Each 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
Fund, by a majority of the outstanding shares of the Fund, 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.

    SIMC and the Trust have obtained an exemptive order from the SEC that
permits SIMC, with the approval of the Trust's Board of Trustees, to retain
sub-advisers unaffiliated with SIMC for the Funds without submitting the
sub-adviser agreements to a vote of the Fund's shareholders. The exemptive
relief permits SIMC to disclose only the aggregate amount payable by SIMC to the
sub-advisers under all such sub-adviser agreements for the Fund. The Fund will
notify shareholders in the event of any addition or change in the identity of
its sub-advisers.

    World, the sub-adviser to the S&P 500 Index Fund, is a general partnership
which engages in investment management and advisory services. World is entitled
to a fee for its investment sub-advisory services, which is based on the average
monthly market value of the assets of the Fund. For the fiscal period ended
March 31, 2000, World received fees of $771,306. Prior to November 18, 1998,
World was adviser to the Fund, and any fees paid prior to that date were for
advisory services. For the fiscal years ended March 31, 1997 and 1998, World
received advisory fees of $234,127 and $398,677, respectively, from the Fund.
Fees paid to World after November 18, 1998, were paid to World by SIMC for
sub-advisory services.

                     DISTRIBUTION AND SHAREHOLDER SERVICING

    The distribution agreement (the "Distribution Agreement") is renewable
annually and may be terminated by the SEI Investments Distribution Co. (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 is a wholly-owned subsidiary of SEI
Investments.

    The Funds have adopted shareholder servicing plans for the Class A and
Class E shares (the "Service Plans"). Under these Plans, the Distributor may
perform, or may compensate other service providers for performing, the following
shareholder and administrative services: maintaining client accounts; arranging
for bank wires; responding to client inquiries concerning services provided on
investments; assisting clients in changing dividend options, account
designations and addresses; sub-accounting; providing information on share
positions to clients; forwarding shareholder communications to clients;
processing purchase, exchange and redemption orders; and processing dividend
payments. Under the Service Plans, the Distributor may retain as a profit any
difference between the fee it receives and the amount it pays to third parties.

    Certain institutions may also charge separate fees for 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 A and Class E shareholders offering shares to their customers may
be required to register as dealers pursuant to state laws.

                                  PERFORMANCE

    From time to time, a Fund may advertise yield. These figures will be based
on historical earnings and are not intended to indicate future performance. The
yield of a Fund refers to the annualized income generated by an investment in
such Fund 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:
                              6
        Yield = 2[(a-b/cd + 1) - 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

                                      S-20
<PAGE>
    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 Fund invests in, changes in interest rates
on money market instruments, changes in the expenses of the Fund and other
factors. For the 30-day period ending March 31, 2000, the yield for the Class A
S&P 500 Index Fund was 0.78%, the yield for the Class E S&P 500 Index Fund was
0.93% and the yield for the Class A Bond Index Fund was 6.34%.

    From time to time, each Fund may advertise total return. The total return of
a Fund refers to the average compounded rate of return to a hypothetical
investment for designated time periods (including, but not limited to, the
period from which the Fund commenced operations through the specified date),
assuming that the entire investment is redeemed at the end of each period. In
particular, total return will be calculated according to the following formula:
                n
        P(1 + T) = 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.

    Based on the foregoing, the average annual total return for the Funds from
inception through March 31, 2000, and for the one, five and ten year periods
ended March 31, 2000 were as follows:

                       PURCHASE AND REDEMPTION OF SHARES

    The purchase and redemption price of shares is the net asset value of each
share. A Fund's securities are valued by SEI Management pursuant to valuations
provided by an independent pricing service (generally the last quoted sale
price). Securities having maturities of 60 days or less at the time of purchase
will be valued using the amortized cost method. Pricing services may use a
matrix system to determine valuations of 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. Pricing services may also provide market quotations. The procedures
of pricing service and their valuations are reviewed by the officers of the
Trust under the general supervision of the Trustees. Fund securities listed on a
securities exchange for which market quotations are available are valued at the
last quoted sale price on each Business Day (defined as days on which the New
York Stock Exchange ("NYSE") is open for business ("a 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.

    Shares of a Fund may be purchased in exchange for securities included in
that Fund subject to SEI Management's determination that the securities are
acceptable. Securities accepted in an exchange will be valued at the 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.

    SEI Management will not accept securities for a Fund unless: (1) such
securities are appropriate for the Fund at the time of the exchange; (2) such
securities are acquired for investment and not for resale; (3) the Shareholder
represents and agrees that all securities offered to the Trust for the Fund are
not

                                      S-21
<PAGE>
subject to any restrictions upon their sale by the Fund under the 1933 Act, or
otherwise; (4) such securities are traded on the American Stock Exchange, the
NYSE 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 (5) the securities may be acquired under the
investment restrictions applicable to the Fund.

    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 NYSE is restricted, or during the existence of an emergency (as
determined by the SEC by rule or regulation) as a result of which disposal or
evaluation of the portfolio securities is not reasonably practicable, or for
such other periods as the SEC may by order permit. The Trust also reserves the
right to suspend sales of shares of the Fund for any period during which the
NYSE, SEI Management, the Distributor and/or the Custodian is not open for
business. The NYSE will not open in observance of the following holidays: New
Year's Day, Martin Luther King, Jr. 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 Fund 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
Fund 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 Fund
redeemed.

                                     TAXES

    The following discussion of federal income tax consequences is based on 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.

QUALIFICATION AS A RIC

    Each Fund intends to qualify as a "regulated investment company" ("RIC") as
defined under Subchapter M of the Code. By following such a policy, each Fund
expects to eliminate or reduce to a nominal amount the federal income taxes to
which such Fund may be subject. In order to qualify for treatment as a RIC under
the Code, a Fund 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) and 90% of its net tax-exempt interest
income, if any (the excess of its tax-exempt interest income over certain
deductions attributable to that income), ("Distribution Requirement") and must
meet several additional requirements. Among these requirements are the
following: (i) at least 90% of a Fund's gross income each taxable year must be
derived from dividends, interest, payments with respect to securities loans,
gains from the sale or other disposition of stocks or securities or certain
other income (including gains from options, futures or forward contracts)
derived with respect to its business of investing in stocks or securities;
(ii) at the close of each quarter of a Fund's taxable year, at least 50% of the
value of its total assets must be represented by cash and cash items, U.S.
Government securities, securities of other RICs and other securities, with such
other securities limited, in respect of any one issuer, to an amount that does
not exceed 5% of the value of the Fund's total assets and that does not
represent more than 10% of the outstanding voting securities of the issuer; and
(iii) at the close of each quarter of a Fund'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 are

                                      S-22
<PAGE>
engaged in the same, similar or related trades or businesses, if the Fund owns
at least 20% of the voting power of such issuers.

    Notwithstanding the Distribution Requirement described above, a Fund will be
subject to a nondeductible 4% federal excise tax to the extent it fails to
distribute to its shareholders 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 (and any retained
amount from the prior calendar year).

    If a Fund's distributions exceed its taxable income and capital gains
realized during a taxable year, all or a portion of the distributions made in
the same taxable year may be recharacterized as a return of capital to
shareholders. A return of capital distribution will generally not be taxable,
but will reduce each shareholder's cost basis in a Fund and result in a higher
reported capital gain or lower reported capital loss when those shares on which
the distribution was received are sold.

    Although each Fund intends to distribute substantially all of its net
investment income and capital gains for any taxable (I.E., fiscal) year, a Fund
will be subject to Federal income taxation to the extent any such income or
gains are not distributed. If a Fund fails to qualify as a RIC for any year, all
of its income will be subject to tax at corporate rates, and its distributions
(including capital gains distributions) will be taxable as ordinary income
dividends to its shareholders, subject to the dividends received deduction for
corporate shareholders who have held shares for more than 45 days during the
90-day period beginning on the date which is 45 days before the date on which
such shares become exdividend with respect to such dividend. The board reserves
the right not to maintain the qualification of a Fund as a regulated investment
company if it determines such course of action to be beneficial to shareholders.

TAX STATUS OF DISTRIBUTIONS

    Dividends from a Fund'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 Fund's earnings and profits. Dividends paid by the
S&P 500 Index Fund will be eligible for the dividends-received deduction allowed
to corporate shareholders to the extent they are derived from dividends from
domestic corporations, subject to certain limitations; however, dividends
received by a corporate shareholder which qualify for the dividends-received
deduction may be subject to the alternative minimum tax.

    Each Fund 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 a Fund distributes its net capital gains to shareholders, such gains
will not qualify for the dividends received deduction, and they are taxable to
shareholders as long-term capital gains, regardless of the length of time the
shareholder has held shares. Conversely, if a Fund elects to retain its net
capital gains, such Fund 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 Fund will elect to have its
shareholders treated as having received a distribution of such gains, with the
result that they will be required to report such gains on their federal income
tax returns as long-term capital gains, will receive a tax credit for their
allocable share of capital gains tax paid by the Fund on the gains, and will
increase the tax basis for their shares by an amount equal to the deemed
distribution less the tax credit.

    Any gain or loss recognized on a sale, exchange or redemption of shares of a
Fund by a shareholder who is not a dealer in securities will generally, for
individual shareholders, be treated as a long-term capital gain or loss if the
shares have been held for more than twelve months and otherwise will be treated
as short-term capital gain or loss. However, if shares on which a shareholder
has received a net capital gain distribution are subsequently sold, exchanged or
redeemed and such shares have been held for six months or less, any loss
recognized will be treated as a long-term capital loss to the extent of the net
capital gain distribution. Long-term capital gains are currently taxed at a
maximum rate of 20% and short-term capital gains are currently taxed at ordinary
income tax rates.

                                      S-23
<PAGE>
    A Fund will be required in certain cases to withhold and remit to the United
States Treasury 31% of distributions payable to any individual or non-corporate
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 Fund that such shareholder is
not subject to backup withholding. Non-U.S. investors in a Fund may be subject
to U.S. withholding and estate tax and are encouraged to consult their tax
advisor prior to investing in a Fund.

    The S&P 500 Index Fund 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 Fund 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 Fund 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 Fund 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 Fund
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 Fund 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 Fund could
affect (i) the amount and timing of distributions to shareholders and (ii) the
ability of the Fund to satisfy the Distribution Requirement.

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

STATE TAXES

    Neither Portfolio is liable for any income or franchise tax in Massachusetts
if it qualifies as a RIC for Federal income tax purposes. Distributions by the
Funds to shareholders and the ownership of shares may be subject to state and
local taxes. Since state and local tax consequences may differ from the federal
income tax consequences discussed above, shareholders are urged to consult their
tax advisers on state and local tax matters.

                             PORTFOLIO TRANSACTIONS

    The Trust has no obligation to deal with any broker or dealer or group of
brokers or dealers in the execution of transactions in portfolio securities.
Subject to policies established by the Trustees, each adviser is responsible for
placing orders to execute fund transactions. In placing orders, it is the
Trust's policy to seek to obtain the best net results taking into account such
factors as price (including the applicable dealer

                                      S-24
<PAGE>
spread), size, type and difficulty of the transaction involved, the firm's
general execution and operational facilities, and the firm's risk in positioning
the securities involved. While each adviser 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 broker or dealer, but,
subject to the Trust's policy of seeking the best net results, dealers who
provide supplemental investment research to an adviser 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 an adviser under its
Investment Advisory Agreement, and the expenses of an adviser will not
necessarily be reduced as a result of the receipt of such supplemental
information.

    The money market securities in which the Funds invest are traded primarily
in the over-the-counter market and generally do not involve either brokerage
commissions or transfer taxes. Bonds and debentures are usually traded
over-the-counter, but may be traded on an exchange. Where possible, each adviser
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. The cost of
executing portfolio securities transactions of the Fund will primarily consist
of dealer spreads and underwriting commissions.

    Each Fund may execute brokerage or other agency transactions through the
Distributor, a registered broker-dealer, for a commission, in conformity with
the 1940 Act, the Securities Exchange Act of 1934 (the "1934 Act") and the rules
and regulations thereunder. Under these provisions, the Distributor is permitted
to receive and retain compensation for effecting portfolio transactions for a
Fund on an exchange if a written contract is in effect between the Distributor
and the Trust expressly permitting the Distributor to receive and retain such
compensation. These provisions further require that commissions paid to the
Distributor by the Trust for exchange transactions not exceed "usual and
customary" brokerage commissions. The rules define "usual and customary"
commissions to include amounts which are "reasonable and fair compared to the
commission, fee or other remuneration received or to be received by other
brokers in connection with comparable transactions involving similar securities
being purchased or sold on a securities exchange during a comparable period of
time." 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, each adviser 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 Fund turnover rate will normally not exceed 100% for
any Fund. A Fund 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 Fund to receive
favorable tax treatment.

    The portfolio turnover rate for the S&P 500 Index Fund for the fiscal years
ending March 31, 1998, 1999 and 2000 were 4%, 7%, and 7%, respectively. The
portfolio turnover rate for the Bond Index Fund for the fiscal years ending
March 31, 1998, 1999, and 2000 were 44%, 40%, and 47%, respectively.

                                      S-25
<PAGE>
    For the fiscal years ended March 31, 1998, 1999, and 2000, the S&P 500 Index
Fund paid brokerage commissions of $89,956, $115,647, and $132,041.69,
respectively. For the fiscal years ended March 31, 1998, 1999, and 2000, the
Bond Index Fund paid no brokerage commissions.

                             DESCRIPTION OF SHARES

    The Declaration of Trust authorizes the issuance of an unlimited number of
shares of each Fund, each of which represents an equal proportionate interest in
such Fund. Each share upon liquidation entitles a shareholder to a pro rata
share in the net assets of the Fund. 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.

                                 CODE OF ETHICS

    The Board of Trustees of the Trust has adopted a code of Ethics pursuant to
Rule 17j-1 under the 1940 Act. In addition, the investment advisers and
Distributor have adopted Codes of Ethics pursuant to Rule 17j-1. These Codes of
Ethics apply to the personal investing activities of trustees, officers and
certain employees ("access persons"). Rule 17j-1 and the Codes of Ethics are
designed to prevent unlawful practices in connection with the purchase or sale
of securities by access persons. Under each Code of Ethics, access persons are
permitted to engage in personal securities transactions, but are required to
report their personal securities transactions for monitoring purposes. In
addition, certain access persons are required to obtain approval before
investing in initial public offerings or private placements. Copies of these
Codes of Ethics are on file with the SEC, and are available to the public.

                                 VOTING RIGHTS

    Each share held entitles the shareholder of record to one vote. Shareholders
of each Fund or class will vote separately on matters pertaining solely to that
Fund or class, such as any distribution plan. As a Massachusetts business trust,
the Trust is not required to hold annual meetings of shareholders, but aproval
will be sought for certain changes in the operation of the Trust and for the
election of Trustees under certain circumstances. In addition, a Trustee may be
removed by the remaining trustees or by shareholders at a special meeting called
upon written request of shareholders owning at least 10% of the outstanding
shares of the Trust. In the event that such a meeting is requested, the Trust
will provide appropriate assistance and information to the shareholders
requesting the meeting.

                             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

                                      S-26
<PAGE>
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.

              CONTROL PERSONS AND PRINCIPAL HOLDERS OF SECURITIES

    As of July 1, 2000, 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 Funds. 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:
