MANAGEMENT'S DISCUSSION AND ANALYSIS OF FUND PERFORMANCE
- --------------------------------------------------------------------------------
SEI INSTITUTIONAL INVESTMENTS TRUST -- MAY 31, 1998
LARGE CAP FUND
OBJECTIVE: The Large Cap Fund seeks to provide long-term growth of
capital and income.
STRATEGY: The Large Cap Fund employs a multi-manager structure to gain
exposure to the entire large cap sector, adding value through stock selection
while minimizing risk in the form of capitalization, valuation and economic
sector exposures. The Fund is jointly sub-advised by six investment managers.
Assets of the Portfolio are strategically allocated among its sub-advisers, each
of which has responsibility for stock selection for its respective assets under
management. Each of the sub-styles assumes a different importance in determining
overall style risk, and must therefore be weighted accordingly.
ANALYSIS: The Large Cap Fund returned 33.36% for the fiscal year ended May
31, 1998 outperforming the Russell 1000 Index return of 30.71% over the same
time period. The large cap equity market enjoyed another strong advance as the
economy remained strong with relatively low and stable interest rates and robust
corporate profits. In addition, high quality large-cap stocks provided a safe
haven for investors from Asia's economic difficulties.
Technology, financial services and drug companies continue to benefit from
the current economic environment and enjoyed another strong year. The cyclical
industries, helped by the low unemployment rate, of retail, chemicals and autos
moved sharply higher during the year. The proliferation of the internet and
advances in telecommunications pushed the stock prices of media and phone
companies higher as well.
The Asian crisis put pressure on companies with a significant exposure to
this region such as select technology and consumer companies. A large oil supply
and an abnormally warm winter in the United States, largely caused by El Nino,
pushed oil prices lower along with the stock prices for the oil companies. The
continued threat of unfavorable legislation against the tobacco companies
hampered the performance of their stock prices as well.
The fund is positioned to take advantage of the expected slowing of
corporate profit growth. Stock selection will take on greater importance as
companies will be highly rewarded for maintaining robust earnings growth
compared to other companies as it becomes increasingly more difficult to provide
the level of earnings growth corporations have provided during the recent past.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FUND PERFORMANCE
- --------------------------------------------------------------------------------
SEI INSTITUTIONAL INVESTMENTS TRUST -- MAY 31, 1998
SMALL CAP FUND
OBJECTIVE: The Small Cap Fund seeks to provide capital appreciation.
STRATEGY: The Small Cap Fund's investment philosophy is to add value
through stock selection while minimizing risk in the form of capitalization,
valuation and economic sector exposures. The Fund invests in stocks of companies
whose prices appear low relative to certain fundamental characteristics as well
as companies that are in an early stage or at a transitional point in their
development and demonstrated or have potential for above average capital growth.
The Small Cap Fund is sub-advised by eight investment managers, who are
responsible for the stock selection of the investment portfolio.
Each sub-adviser employs a unique investment process that allows the Fund
to benefit from a variety of sub-styles in the small cap area of the market. The
various sub-styles include: price/book, price/earnings, deep-value, momentum,
long-term sustainable growth, micro-cap and relative price strength.
ANALYSIS: For the fiscal year ended May 31, 1998 the Small Cap Fund
returned 26.68% compared to the benchmark Russell 2000 index which returned
21.24%. Despite the strong absolute returns delivered by small cap stocks, such
issues continued to lag larger cap securities in the U.S. market, as they have
since 1993. In addition, for the second straight year, the value sector of the
small cap market substantially outperformed the growth sector with the Russell
2000 Value Index returning 26.7% versus a return of 15.8% for the Russell 2000
Growth Index.
From an industry perspective the best performers were those with close
ties to the domestic consumer including the construction and retail names. These
stocks benefited from the strong domestic economy featuring record low
unemployment, high consumer confidence and low interest rates. Airlines also
produced good returns over the fiscal year as high load factors and lower fuel
costs added up to strong profit growth for many companies in the group. Banks
continued to produce market-beating returns as well, benefiting from both the
low interest rate environment and merger activity in the sector. On the losing
side of the roster were the stocks with earnings ties to the troubled economies
of Asia. Technology stocks were particularly hard hit as the collapse of several
Asian currencies resulted in both canceled export orders from the region as well
as increased price competition for domestic business. Energy stocks also lagged
over the fiscal year as abundant supplies combined with reduced demand from Asia
pushed crude prices to their lowest levels in ten years. The strong benchmark
relative performance of the Fund was primarily attributable to stock selection
decisions by the sub-advisors. Stock picking among the consumer and financial
names was particularly positive for relative performance.
The Fund continues to target a style-neutral position relative to the
benchmark Russell 2000 index. This minimizes uncompensated style and industry
risks and focuses on the stock selection ability of the Fund's sub-advisors.
Polynous Capital Management ("Polynous") was added as a sub-adviser to the Fund
in January of 1998 bringing an anti-momentum approach to small cap investing
that complements other sub-advisors in the Fund. It is our expectation that the
addition of this sub-style investment will benefit the Fund over time.

CORE FIXED INCOME FUND
OBJECTIVE: The Core Fixed Income Fund seeks to provide current income
consistent with the preservation of capital.
STRATEGY: The Core Fixed Income Fund's investment strategy focuses on
sector rotation, both among and within sectors, and issue selection. Risk is
principally controlled by explicitly limiting fund interest rate exposure
relative to the Lehman Aggregate Bond Index. The Fund's sub-advisers focus on
four key areas in determining portfolio structure: duration weighting, term
structure, sector allocation, and issue selection. While the duration and term
structure decision underlie the implementation process, the advisers primarily
concentrate on sector and issue selection to add value. In addition, the
sub-advisers may use futures and options primarily for tactical hedging purposes
and to implement portfolio strategies more efficiently.
ANALYSIS: For the fiscal year ended May 31, 1998 the Core Fixed Income
Fund returned 11.60% strongly outperforming the Lehman Aggregate Bond Index
return of 10.91%. The Fund's longer duration posture and barbelled yield curve
structure were significant contributors to positive relative performance. In
addition, the Fund's overweight to mortgage-backed securities combined with
security selection within that sector added value throughout the period. Sector
and security selection within the corporate sector served to dampen returns for
the period. An overweight to the corporate sector was maintained throughout the
majority of the fiscal year. The Fund experienced significant cash flows
throughout the period which also acted as a modest drag on performance. Fund
assets under management grew from $331 to $795 million throughout the fiscal
year.
The U.S. Treasury market posted strong gains for the fiscal year period.
Having recovered from the effects of a March 1997 Federal Reserve rate hike,
news of a moderating economy and the nonexistence of inflationary pressures
fueled the domestic bond markets. As capital market volatility and economic
crisis surfaced in Asia, the U.S. investment-grade bond market was a major
benefactor of a global flight-to-quality which spurred demand for safe-haven
U.S. Treasury securities. In January, yields on 30-year U.S. Treasury bonds
touched 5.66%, the lowest point since the Treasury began issuing that maturity
in 1977. The bond market experienced a back-up in yields in February and March,
as a

SEI INSTITUTIONAL INVESTMENTS TRUST -- MAY 31, 1998
semblance of stability in Asia lower expectations of the crisis' likely slowing
effect on the U.S. economy. However, the bond market resumed its ascent in May
as a renewed bout of Asian contagion buoyed U.S. securities, with the Japanese
yen falling to a seven-year low versus the U.S. dollar. Overall, yield levels
ended the fiscal period dramatically lower. 30-year yields fell to 5.80% from
6.91%, an astounding 1.11% decline. In contrast, yields on securities with less
than one year to maturity were largely unchanged throughout the period as Fed
inaction kept the short-end of the curve anchored. As a result of the declining
yield levels and flattening yield curve, the Fund's longer duration and barbell
yield curve emphasis added strongly to performance.
During the above market scenario, mortgage-backed securities provided the
best market sector performance on a duration-adjusted basis. Overall,
mortgage-backed securities gained as a result of their higher yield levels,
relatively low market volatility, and significant demand from yield-seeking
investors and CMO originators. The 10-year Treasury yield, which is used as a
base for most mortgage calculations, declined to 5.55% from 6.66% during the
fiscal year. Throughout much of the 111 basis point decline in 10-year yields
the mortgage market had apparently ignored the associated rise in prepayments.
However, record refinancing levels in January and peak prepayments reached in
March highlighted the largest wave of mortgage refinancings since 1993. Discount
securities, which actually benefit from rising prepayments, began to outperform
in conjunction with these market movements. Throughout most of the period, the
Fund remained overweighted in the mortgage-backed sector, which benefited
results. Individual issues were concentrated in discount coupons and structured
securities, such as commercial mortgages, which provided additional prepayment
protection and positively impacted relative performance.
Investment-grade corporate securities posted the worst broad sector
performance for the period. Despite strong performance during the initial stages
of the fiscal year, the crisis in Southeast Asia caused significant spread
widening across the credit spectrum. The Yankee sub-sector was hit particularly
hard, as many of these issuers were more directly impacted by the Asian
situation. As yield levels fell, new supply proliferated as issuers rushed to
lock in low long-term borrowing rates, placing further upward pressure on
corporate spreads. An overweight to corporate issues throughout much of the
period detracted from relative performance. Tobacco bonds were negatively
impacted throughout the period as the historic agreement between the tobacco
industry, the states, and private attorneys representing smokers was hotly
debated in Congress. Uncertainty surrounding the potential final price tag of
the settlement and the status of future legal liability for the industry caused
uncertainty for future credit quality. Fund holdings in Phillip Morris and RJR
Nabisco, the two largest tobacco companies, were negatively impacted as a
result.

INTERNATIONAL EQUITY FUND
OBJECTIVE: The International Equity Fund seeks to provide long-term
capital appreciation through investments in equity securities of non-U.S.
issuers.
STRATEGY: The International Equity Fund is diversified across twenty-one
markets and includes commitments to large-cap and small-cap shares. The Fund
also seeks to provide U.S. investors with a vehicle for international
diversification, which can reduce variability of Fund returns to the extent that
foreign markets have a relatively low correlation with the U.S. market. Exposure
is also maintained in growth and value styles of active management. As of May
31, 1998 the Fund employed three sub-advisers, each providing a unique regional
or style management specialty. Allocations to the sub-advisers are carefully
managed to ensure proper geographic and market exposure. Emphasis is placed on
active security selection as the principal source of value-added as opposed to
active country allocation. The Fund does not hedge foreign currency exposure.
ANALYSIS: The International Equity Fund returned 10.4% for the fiscal
period ended May 31, 1998 underperforming the MSCI EAFE Index return of 11.1%
over the same time period. Strong stock selection in Europe was offset by
weakness in Asia. The currency devaluation in Thailand triggered a broad-based
decline throughout Asia. Hong Kong fell 42.7% for the year, while Malaysia fell
68%. Even the already stagnating economy in Japan was off 27% for the year ended
May 1998. International money flows quickly moved to Europe and the U.S. at the
end of 1997 and have continued throughout 1998. The significance of the crisis
in Asia is illustrated in the significant regional weighting shift that occurred
in the index. MSCI EAFE Index on May 1997 had 58% in Europe and 42% in Asia.
Only one year later, the index had a 73% exposure to Europe and 27% to Asia.
Japan has fallen to 20% of the index from 31% a year earlier. What has crippled
Asia has fueled European markets to new highs. France, Spain and Switzerland
gained 69%, 70% and 57% respectively for the one year period.
In this volatile environment, our strategy managed to keep pace with the
index. We benefited from our modest 3.0% overweight to France and 1.5%
underweight to Japan. Both weighting decisions resulted from stock selection
decisions of the underlying sub-advisors.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FUND PERFORMANCE
- --------------------------------------------------------------------------------
SEI INSTITUTIONAL INVESTMENTS TRUST -- MAY 31, 1998
European markets benefited from solid earnings announcements, steady economic
growth and heightened merger and acquisition activity. On the contrary, sluggish
economic growth and low domestic sentiment about future prospects continued to
plague the Japanese market.
Following extensive research of the Developed Non-US equity strategy we
restructured the portfolio. On April 1, 1998 we replaced Lazard Asset Management
with Scottish Widows Investment Management Limited. Turnover of key
professionals in Lazard's investment team was the primary reason for their
replacement. Scottish Widows is a European specialist whose portfolio is
concentrated in the top names in the region. Farrell-Wako Global Investment
Management Inc. failed to perform up to our expectations and did not provide the
style exposure originally expected. SGY Asset Management's (Formerly Yamaichi
International Capital Management). Asia Ex-Japan mandate was expanded to include
Japan. Finally, Japan's weakness forced our small cap exposure to less than 2.0%
of the entire strategy. At this weight, a separate allocation to Seligman
Henderson Co., whose specialty was small cap Japan, was no longer feasible. The
decision to terminate Seligman Henderson was driven by portfolio structure.

REPORT OF INDEPENDENT ACCOUNTANTS
- --------------------------------------------------------------------------------
SEI INSTITUTIONAL INVESTMENTS TRUST -- MAY 31, 1998
To the Board of Trustees and Shareholders of
The SEI Institutional Investments Trust:
In our opinion, the accompanying statements of net assets for the Large Cap Fund
and International Equity Fund and the statements of assets and liabilities,
including the schedules of investments, for the Small Cap Fund and Core Fixed
Income Fund and the related statements of operations and of changes in net
assets and the financial highlights present fairly, in all material respects,
the financial position of the SEI Institutional Investments Trust (the "Trust"),
comprised of the Large Cap Fund, Small Cap Fund, Core Fixed Income Fund, and
International Equity Fund , respectively, at May 31, 1998, the results of its
operations for the year then ended and the changes in its net assets and its
financial highlights for each of the periods presented, in conformity with
generally accepted accounting principles. These financial statements and
financial highlights (hereafter referred to as "financial statements") are the
responsibility of the Trust's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with generally accepted
auditing standards which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at May 31, 1998 by
correspondence with the custodians and brokers and the application of
alternative auditing procedures, where necessary, where securities purchased had
not been settled, provide a reasonable basis for the opinion expressed above.

NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------
SEI INSTITUTIONAL INVESTMENTS TRUST -- MAY 31, 1998
1. ORGANIZATION
SEI Institutional Investments Trust (the "Trust") was organized as a
Massachusetts business trust under a Declaration of Trust dated March 1, 1995.
The Trust commenced operations on June 14, 1996.
The Trust is registered under the Investment Company Act of 1940, as
amended, as an open-end investment company with seven funds: The Large Cap,
Small Cap, Core Fixed Income, and International Equity Funds (each a "Fund" and,
together, the "Funds") are each diversified operational Funds. The Emerging
Markets Equity, International Fixed Income and High Yield Bond Funds are
currently not operational.
2. SIGNIFICANT ACCOUNTING POLICIES
The following is a summary of the significant accounting policies followed by
the Trust. The preparation of financial statements in conformity with generally
accepted accounting principles requires the use of management estimates. Actual
results could differ from the estimates.
SECURITY VALUATION -- Investments in equity securities that are traded on a
national securities exchange (or reported on NASDAQ national market system) are
stated at the last quoted sales price if readily available for such equity
securities on each business day; other equity securities traded in the
over-the-counter market and listed equity securities for which no sale was
reported on that date are stated at the last quoted bid price. Foreign
securities in the International Equity Fund are valued based on quotations from
the primary market in which they are traded. Debt obligations with remaining
maturities in excess of sixty days are valued at the most recently quoted bid
price. Debt obligations with remaining maturities of sixty days or less are
valued at their amortized cost which approximates market value. Securities for
which quotations are not readily available are valued in good faith using
methods determined under general Trustee supervision.
FEDERAL INCOME TAXES -- It is each Fund's intention to qualify as a
regulated investment company for Federal income tax purposes and distribute all
of its taxable income (including net capital gains). Accordingly, no provision
for Federal income taxes is required.
NET ASSET VALUE PER SHARE -- Net asset value per share is calculated on a
daily basis by dividing the assets of each Fund less its liabilities by the
number of outstanding shares of the Fund.
REPURCHASE AGREEMENTS -- Securities pledged as collateral for repurchase
agreements are held by each Fund's custodian bank until maturity of the
repurchase agreement. Provisions of the repurchase agreement and procedures
adopted by the Manager and the Advisers of the Trust ensure that the market
value of the collateral, including accrued interest thereon, is sufficient in
the event of default by the counterparty. The Funds also invest in tri-party
repurchase agreements. Securities held as collateral for tri-party repurchase
agreements are maintained by the broker's custodian bank in a segregated account
until maturity of the repurchase agreement. Provisions of the repurchase
agreements ensure that the market value of the collateral, including accrued
interest thereon, is sufficient in the event of default. If the counterparty
defaults and the value of the collateral declines or if the counterparty enters
into an insolvency proceeding, realization of the collateral by the Funds may be
delayed or limited.
DISCOUNT AND PREMIUM AMORTIZATION -- All amortization is calculated using
the effective interest method over the holding period of the security.
Amortization of premiums and discounts is included in interest income.
EXPENSES -- Expenses that are directly related to one of the Funds are
charged directly to that Fund. Other operating expenses of the Funds are
prorated to the Funds on the basis of relative net assets.
FOREIGN CURRENCY TRANSLATION -- The books and records of the International
Equity Fund are maintained in U.S. dollars on the following basis:
(I) market value of investment securities, assets and liabilities at the
current rate of exchange; and
(II) purchases and sales of investment securities, income and expenses at
the relevant rates of exchange prevailing on the respective dates of such
transactions.
The International Equity Fund does not isolate that portion of gains and
losses on investments in
38
<PAGE>
- --------------------------------------------------------------------------------
equity securities that is due to changes in the foreign exchange rates from that
which is due to change in market prices of equity securities.
The International Equity Fund reports certain foreign currency related
transactions as components of realized gains for financial reporting purposes,
whereas such components are treated as ordinary income for Federal income tax
purposes.
FUTURES CONTRACTS -- Each of the Funds utilized futures contracts during
the period ended May 31, 1998. The Large Cap, Small Cap, and International
Equity Fund's investment in Index futures contracts is designed to enable the
Funds to more closely approximate the performance of their benchmark indices.
The Core Fixed Income Fund's use of futures contracts is primarily for tactical
hedging purposes. Initial margin deposits of cash or securities are made upon
entering into futures contracts. The contracts are marked to market daily and
the resulting changes in value are accounted for as unrealized gains and losses.
Variation margin payments are paid or received, depending upon whether
unrealized losses or gains are incurred. When the contract is closed, the Fund
records a realized gain or loss equal to the difference between the proceeds
from (or cost of) the closing transaction and the amount invested in the
contract.
Risks related to futures contracts include the possibility that there may
not be a liquid market for the contracts, that changes in the values of the
contract may not directly correlate with changes in the values of the underlying
securities, and that counterparty to a contract may default on its obligation to
perform.
OPTION SELLING/PURCHASING -- Each Fund may invest in financial options
contracts solely for the purpose of hedging its existing portfolio securities,
or securities that the Fund intends to purchase, against fluctuations in fair
value caused by changes in prevailing market interest rates. When the Fund sells
or purchases an option, an amount equal to the premium received or paid by the
Fund is recorded as a liability or an asset and is subsequently adjusted to the
current market value of the option written or purchased. Premiums received or
paid from purchasing options which expire unexercised are treated by the Fund on
the expiration date as realized gains or losses. The difference between the
premium and the amount paid or received on effecting a closing purchase or sale
transaction, including brokerage commissions, is also treated as a realized gain
or loss. If an option is exercised, the premium paid or received is added to the
cost of the purchase or proceeds from the sale in determining whether the Fund
has realized a gain or a loss on investment transactions.
TBA AND OTHER PURCHASE COMMITMENTS -- The Funds may enter into purchase
commitments to purchase securities for a fixed price at a future date. Purchase
commitments may be considered securities and involve a risk of loss if the value
of the security to be purchased declines prior to settlement date, which risk is
in addition to the risk of decline in the value of a Fund's other assets.
Unsettled purchase commitments are valued at the current market value of the
underlying securities, according to the procedures described under "Security
Valuation" above.
STRUCTURED NOTES AND INDEXED NOTES -- The Core Fixed Income Fund may invest
in structured notes and indexed notes whose values are linked either directly
and inversely to changes in foreign currency exchange rates, interest rates,
indices, or other reference instruments. The values of these instruments may be
more volatile than the rates, indices, or instruments to which they refer, but
any loss is limited to the amount of the original investment.
DISTRIBUTIONS -- Distributions from net investment income and net realized
capital gains are determined in accordance with U.S. Federal income tax
regulations, which may differ from those amounts determined under generally
accepted accounting principles. These book/tax differences are either temporary
or permanent in nature. To the extent these differences are permanent, they are
charged or credited to paid in capital in the period that the difference arises.
Accordingly for the Small Cap Fund, $9,000 was reclassified from accumulated net
realized gain to accumulated net investment income. This reclassification has no
effect on net assets or net asset values per share.

NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------
SEI INSTITUTIONAL INVESTMENTS TRUST -- MAY 31, 1998
OTHER -- Security transactions are recorded on the trade date of the
security purchase or sale. Cost used in determining net realized capital gains
and losses on the sale of securities are those of the specific securities sold.
Dividend income is recognized on the ex-dividend date, and interest income is
recognized using the accrual basis of accounting.
The market values of the Core Fixed Income Fund's investments will change
in response to interest rate changes and other factors. During periods of
falling interest rates, the values of fixed income securities generally rise.
Conversely, during periods of rising interest rates, the values of such
securities generally decline. Changes by recognized rating agencies in the
ratings of any fixed income security and in the ability of an issuer to make
payments of interest and principal may also affect the value of these
investments.
3. MANAGEMENT, INVESTMENT ADVISORY AND DISTRIBUTION AGREEMENTS
The Trust and SEI Investments Fund Management (the "Manager"), are parties to a
management agreement (the "Agreement") dated March 1, 1995. Under this
Agreement, the Manager provides administrative and shareholder servicing for an
annual fee of .05% of the average daily net assets of each Fund. The Manager has
agreed to waive a portion of its fee so that the total annual expenses of each
Fund will not exceed certain voluntary expense limitations adopted by the
Manager.
The Trust and SEIInvestments Distribution Co. (the "Distributor") are
parties to a distribution agreement dated June 14, 1996 pursuant to which the
Distributor provides distribution-related services to the Trust. The Distributor
is not currently entitled to any fee for performing these services.

adviser to each Fund. In connection with serving as investment adviser, SIMC is
entitled to a fee, that is calculated daily and paid monthly, at an annual rate
of .40% of the Large Cap Fund's average daily net assets, at an annual rate of
.65% of the Small Cap Fund's average daily net assets, at an annual rate of .30%
of the Core Fixed Income Fund's average daily net assets and at an annual rate
of .51% of the International Equity Fund's average daily net assets. The Adviser
has agreed to waive a portion of its fee so that the total annual expenses of
each Fund will not exceed certain voluntary expense limitations adopted by the
Adviser.
Alliance Capital Management L.P., American Express Asset Management,
Provident Investment Counsel, Inc., LSV Asset Management and Mellon Equity
Associates, LLP each serve as an investment sub-adviser to a portion of the
assets of the Large Cap Fund and are parties to investment sub-advisory

- --------------------------------------------------------------------------------
sub-adviser to a portion of the assets and is party to an agreement with the
Trust and SIMC dated March 23, 1998.
4. ORGANIZATIONAL COSTS AND TRANSACTIONS WITH AFFILIATES
Organizational costs have been capitalized by the Funds and are being amortized
over sixty months commencing with operations. In the event any of the initial
shares are redeemed by any holder thereof during the period that the Fund is
amortizing its organizational costs, the redemption proceeds payable to the
holder thereof by the Fund will be reduced by the unamortized organizational
costs in the same ratio as the number of initial shares being redeemed bears to
the initial shares outstanding at the time of redemption.
Certain officers and/or trustees of the Trust are also officers of the
Manager. The Trust pays each unaffiliated Trustee an annual fee for attendance
of quarterly, interim and committee meetings. Compensation of officers and
affiliated Trustees of the Trust is paid by the Manager.
The Funds used SEI Institutional Transfer Agency for shareholder services
and paid the following amounts as of May 31, 1998: $14,740 for Large Cap, $4,065
for Small Cap, $9,730 for Core Fixed Income and $7,400 for International Equity.
The Large Cap, Small Cap and International Equity Funds also used the
Distributor as an agent in placing repurchase agreements. For this service the
Distributor retains a portion of the interest earned as a commission. Such
commissions for the period ended May 31, 1998 were $11,722, $11,735 and $13,956,
respectively.
5. FORWARD FOREIGN CURRENCY CONTRACTS
The International Equity Fund enters into forward foreign currency exchange
contracts as hedges against portfolio positions. Such contracts, which are
designed to protect the value of the Fund's investment securities against a
decline in the value of the hedged currency, do not eliminate fluctuations in
the underlying prices of the securities; they simply establish an exchange rate
at a future date. Also, although such contracts tend to minimize risk of loss
due to a decline in the value of a hedged currency, at the same time they tend
to limit any potential gain that might be realized should the value of such
foreign currency increase.
The following forward foreign currency contracts were outstanding at May
31, 1998:

7. CONCENTRATION OF RISKS
The International Equity Fund invests in securities of foreign issuers in
various countries. These investments may involve certain considerations and
risks not typically associated with investments in the United States, as a
result of, among other factors, the possibility of future political and economic
developments and the level of governmental supervision and regulation of
securities markets in the respective countries.
