SEI INSTITUTIONAL INVESTMENTS TRUST -- NOVEMBER 30, 1999 (UNAUDITED)



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,
Large Cap Value, Large Cap Growth, 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 exchangeprevailing on the respective dates of such
transactions.
     The International Equity Fund does not isolate that portion of gains and
losses on investments in


                                                                             33

                                                                          <PAGE>


NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

SEI INSTITUTIONAL INVESTMENTS TRUST -- NOVEMBER 30, 1999 (UNAUDITED)

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 November 30, 1999. 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 -- The Core Fixed Income 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. The Large Cap, Small Cap, and International Equity Funds may invest in
financial options contracts. 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.



     34
     <PAGE>



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


     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.

SEI INSTITUTIONAL INVESTMENTS TRUST -- NOVEMBER 30, 1999 (UNAUDITED)

sub-adviser to a portion of the assets of the International Equity
Fund and are parties to investment sub-advisory agreements with the Trust and
SIMC dated June 14, 1996. Scottish Widows Investment Management Limited, Capital
Guardian Trust Company, and Oechsle International Advisers, LLC also serve as
investment sub-advisers to a portion of the assets and are parties to agreements
with the Trust and SIMC dated March 23, 1998, June 29, 1998, and June 22, 1999,
respectively.

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 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 November 30, 1999 were $9,617, $5,176 and
$3,123, 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
November 30, 1999:

                                        IN       UNREALIZED

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.

8. FUTURES CONTRACTS
The following Funds had futures contracts open as of November 30, 1999:
