MANAGEMENT'S DISCUSSION AND ANALYSIS OF FUND PERFORMANCE
- --------------------------------------------------------------------------------
SEI Institutional Managed Trust -- September 30, 1999

                              Large Cap Value Fund

                 Adviser--SEI Investments Management Corporation
                     Sub-Advisers--Mellon Equity Associates
                                   Sanford C. Bernstein
                                   LSV Asset Management
OBJECTIVE
      The Fund seeks to provide long-term growth of capital and income.

STRATEGY
      With respect to this Fund, SEI Investments Management Corporation employs
a multi-manager structure to gain exposure to the entire large cap value sector,
adding value through stock selection while minimizing risk in the form of
capitalization, valuation and economic sector exposures. Assets of the Fund are
strategically allocated among its three sub-advisers, each of whom has
responsibility for stock selection for its respective assets under management.
      Through various investment approaches, each sub-adviser contributes a
unique expertise or substyle to the Fund. LSV Asset Management invests in
companies trading at deep discounts to their intrinsic value. Mellon Equity
Associates invests primarily in large cap value stocks that are representative
of the market. Sanford C. Bernstein incorporates intensive fundamental research
to invest in undervalued stocks where there is a relationship between the
current price, its future earnings power and dividend producing capability.
      Each of the aforementioned sub-styles assumes a different importance in
determining overall style risk, and must therefore be weighted accordingly.

ANALYSIS
      The Large Cap Value Fund posted a 17.1% return for the fiscal year ended
September 30, 1999 as a result of continued moderate inflation in the United
States, a resurgence of global economies which lifted commodity prices, and
controls on the production of oil.
      Even within the Value area of the marketplace there was still a heavy
appetite for technology oriented names, which lead performance for the year. The
traditional slow growth industry of telephones was bolstered by a spate of
mergers and broadening out of product lines to satisfy the need for bandwidth
driven by the proliferation of the Internet. Financial service names were
somewhat bolstered by ongoing moderate inflation and continued mergers. Basic
industries and commodities rebounded from lows as the global economy improved
and OPEC instituted oil production constraints.
      The Fund performed relatively in line with the benchmark for the year
benefiting from strong stock selection, which offset weak performance from
industry exposures. Strong stock selection was centered within the banking and
finance industries. An overweight to retail and underweight to telephone stocks
caused performance to lag.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FUND PERFORMANCE
- --------------------------------------------------------------------------------
SEI Institutional Managed Trust -- September 30, 1999

                              Large Cap Growth Fund
                 Adviser--SEI Investments Management Corporation
                 Sub-Advisers--Alliance Capital Management, L.P.
                               TCW Funds Management Inc.
                               Provident Investment Counsel
OBJECTIVE
      The investment objective of the Large Cap Growth Fund is capital
appreciation.

STRATEGY
      With respect to this Fund, SEI Investments Management Corporation employs
a multi-manager structure to gain exposure to the entire large cap growth
sector, adding value through stock selection while minimizing risk in the form
of capitalization, valuation and economic sector exposures. Assets of the Fund
are strategically allocated among its sub-advisers, each of which has
responsibility for stock selection for its respective assets under management.
      Through various investment approaches, each sub-adviser contributes a
unique expertise or sub-style to the Fund. Alliance Capital Management, L.P.
invests in large cap growth stocks that are representative of the market. TCW
Funds Management Inc. invests bottom-up primarily in large-cap growth stocks
while assessing the operating prospects of each prospective holding. Provident
Investment Counsel invests primarily in mid-cap and large-cap stocks which are
expected to demonstrate very high long term earnings growth. Each of the
aforementioned sub-styles assumes a different importance in determining overall
style risk, and must therefore be weighted accordingly.

ANALYSIS
      The Large Cap Growth Fund posted a return of 37.7% for the fiscal year
ended September 30, 1999 as this sector once again dominated the performance of
the broad domestic equity market driven by continued strong corporate profits,
moderate inflation and a relatively calm international landscape.
      Returns were driven by the largest technology names in the index,
especially those who derive benefit from the proliferation of the Internet. This
area of the market significantly exceeded the performance of smaller companies
and the value sector of the market. Performance across individual securities was
highly variable for the year with companies in slower growth industries
experiencing moderate returns and those that failed to meet analyst expectations
punished severely.
      The Fund's return relative to the market was attributable to both
individual security selection as well as industry and style exposures. Strong
stock selection was experienced in the miscellaneous finance area, where
companies derived strong revenue growth from Internet trading, and the business
services industry. From an industry perspective the Fund's active bet to
underweight the more slowly growing drugs and food industries proved to be
positive.
      The underlying manager structure remained constant during the year. Fund
risk continues to be driven almost exclusively by stock specific issues, with
industry and style exposures making up the residual.

OBJECTIVE
      The investment objective of the Tax-Managed Large Cap Fund is to achieve
high long-term after-tax returns for its shareholders.

STRATEGY
      With respect to this Fund, SEI Investments Management Corporation employs
a multi-manager structure to gain exposure to the entire U.S. large cap market,
adding value through stock selection in a tax-aware framework while minimizing
risk in the form of capitalization, valuation and economic sector exposures.
Assets of the Fund are strategically allocated among its sub-advisers, each of
which has responsibility for stock selection for its respective assets under
management.
      Through various investment approaches, each sub-adviser contributes a
unique expertise to the Fund. Alliance Capital Management, L.P. invests in the
large cap growth area of the market employing tax-aware trading techniques.
Sanford C. Bernstein and Company, Inc. invests in the large-cap value area of
the market utilizing a sophisticated tax-aware optimizer to manage after-tax
return and risk exposures. Mellon Equity Associates invests in both value and
growth large-cap stocks through a quantitative process and aggressively harvests
tax-losses in the portfolio. Each of the aforementioned managers is weighted to
minimize uncompensated style and industry risks relative to a broad-based large
cap benchmark.

ANALYSIS
      The Tax-Managed Large Cap Fund returned 32.6% for the period ended
September 30, 1999. The domestic equity marketplace, and large cap stocks in
particular, benefited from continued domestic economic prosperity and
strengthening foreign economies particularly centered in Asia. Against this
backdrop and with the Fed lowering rates late last year, large cap companies as
a whole produced better than expected growth.
      Once again growth stocks outperformed large cap, driven in large part by
the technology sector which has benefited from the proliferation of the
Internet. On the value side low rates and a strong economy helped financials
produce positive returns. One area of the marketplace which experienced a
resurgence after being maligned for some time was the basic industry and
commodity sector. This was driven by increased demand globally as well as OPEC
led oil production limitations.

                                                                               3

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FUND PERFORMANCE
- --------------------------------------------------------------------------------
SEI Institutional Managed Trust -- September 30, 1999

      The Fund experienced impressive relative performance during the quarter on
both a pre- and post-tax basis. Fund outperformance can be attributed to both
strong stock selection and relative industry exposures. Specific stocks which
helped performance were spread across industries and included such market
leaders as Cisco Systems, Microsoft, Dow Chemical, Solectron and Morgan Stanley
Dean Witter.
      The current Fund is well positioned to exploit the strong global economy
and looming higher interest rates. The broad diversification and careful risk
control should help to moderate market volatility. The Fund continues to target
a style neutral position to the Russell 1000 Index that controls unnecessary
risk and puts the focus on stock selection from the specialist sub-advisers who
evaluate all Fund transactions in a tax-sensitive manner.

      The Small Cap Value Fund seeks to provide capital appreciation.

STRATEGY
      With respect to this Fund, SEI Investments Management Corporation employs
a multi-manager structure to gain exposure to the entire small cap value sector,

Artisan Partners Limited Partnership seeks to identify companies which are
currently trading below the intrinsic value of the business that have little or
no institutional following. Boston Partners Asset Management, L.P. combines
quantitative and fundamental approaches to identify a company's fundamental
worth. LSV Asset Management invests in companies trading at deep discounts to
their intrinsic value that have exhibited some catalyst to turn

around performance. Mellon Equity Associates adheres to a tightly
risk-controlled philosophy that focuses on stock selection while maintaining
portfolio characteristics very close to that of the Russell 2000 Value Index.
Security Capital is a Real Estate Investment Trust specialist seeking out
publicly traded real estate investment opportunities that provide an attractive
valuation to growth relationship. Each of the aforementioned sub-styles assumes
a different importance in determining overall style risk and must therefore be
weighted accordingly.

ANALYSIS
      The Small Cap Value Fund posted a 4.5% return for the fiscal year ended
September 30, 1999. There were some changes in the Fund over the fiscal year.
First, 1838 Investment Advisers was terminated in June due to style related
issues, they were replaced by Artisan Partners, whose deep value orientation
improved the risk characteristics of the fund. Second, Security Capital was
added to the fund in September to improve the structure of the fund by
eliminating a persistent underweight to REIT's in the fund. Both of these
changes brought the funds characteristics closer in line to the Russell 2000
Value.
      Small cap value stocks lagged their growth brethren as investors
disregarded relative valuations and invested heavily in Internet related names.
During most of the year assets flowed out of small cap value area of the market
into larger and more growth oriented names, which stunted returns. Continued
domestic economic prosperity and moderate inflation allowed for better than
expected earnings growth in many of the small cap value names. Returns across
industries were widely different for the year as technology oriented issues
performed well and commodity oriented names experienced extremely volatile
performance.
      The Fund experienced strong stock selection and moderate outperformance
from industry weightings. In particular, strong stock selection was experienced
in the business services, construction, railroad and travel industries. From an
industry perspective the funds active underweight to interest sensitive stocks,
particularly in the banking industry, contributed positively. An underweight to
the electronics industry moderately detracted from performance.
      The Fund continues to be positioned to capture the opportunities in the
small cap value area of the market under a variety of market conditions. To this
end, the Fund targets a style neutral position relative to the Russell 2000
Value Index to control unnecessary risks and put the focus on stock selection
from the specialist sub-advisers.

strategically allocated among its five sub-advisers, each of which has a
responsibility for stock selection for its respective assets under management.
      Through various investment approaches, each sub-adviser contributes a
particular expertise or sub-style to the Fund. Furman Selz Capital Management
invests primarily in stocks exhibiting relative price strength trading at
attractive valuations. Nicholas-Applegate Capital Management screens stocks for
high and accelerated earnings growth and then selects those with attractive
current prices relative to sustainable cash flow. RS Investment Management
pursues an investment strategy that focuses on emerging growth companies that
exhibit very high revenue growth. Wall Street Associates seeks out micro-cap
stocks with long-term earnings growth potential. Sawgrass Asset Management seeks
to invest in companies that exhibit reasonable relative valuations, strong
earnings momentum and rising analyst expectations. Each of the aforementioned
sub-styles assumes a different importance in determining overall style risk and
must therefore be weighted accordingly.

ANALYSIS
      The Small Cap Growth Fund Class D
posted a 54.6% return for the fiscal year ended September 30, 1999. There were
some changes in the Fund over the fiscal year as Spyglass Asset Management was
terminated due to organizational concerns and performance issues. Sawgrass Asset
Management was added to the fund in the same time period to provide a unique
sub-style to the portfolio. This transition provided greater valuation
sensitivity to the portfolio while maintaining the growth characteristics in
line with the Russell 2000 Growth Index.
      Small cap growth stocks were the second best performing style in the U.S.
equity marketplace for fiscal year 1999. Returns in this area of the marketplace
were driven predominately by stocks that were associated with the Internet in
some way. On balance all non- Internet related stocks within the Small Cap
Growth area of the marketplace continued to experience better than expected
earnings growth than Large Cap stocks. Commodity driven and finance related
names lagged for the year, both from their slower earnings growth relative to
technology names and investor neglect. Apparel and retail stocks continued to
lag the market as several specialty retailers experienced earnings
disappointments driven by poor seasonal offerings.

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

      The Fund's returns were bolstered relative to the index from both industry
weighting and stock specific holdings. In particular, several of the
sub-advisers correctly identified the investing opportunity of Internet stocks
and were able to be early investors in some of the best names. Additionally, our
managers made correct timing decisions to begin investing in more Internet
infrastructure names in areas like semi-conductor capital equipment makers.
These stocks are likely to produce more consistent returns due to the fact that
many of them actually have earnings and demand for the products will only
increase with the proliferation of the Internet. From an industry perspective
the fund's underweights to banks, chemicals, energy and oil were all positive.

      The Fund continues to be positioned to capture the opportunities in the
small cap growth area of the market under a variety of market conditions. To
this end, the Fund targets a style neutral position relative to the Russell 2000
Growth Index to control unnecessary risks and put the focus on stock selection
from the specialist sub-advisers.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FUND PERFORMANCE

SEI Institutional Managed Trust -- September 30, 1999

which will tend to have a higher than average price-to-earnings ratio,
price-to-book ratio, and return on equity, and a lower than average dividend
yield.

ANALYSIS
      The Mid-Cap Fund posted a 16.5% return for the fiscal year ended September
30, 1999 as the continued strength of the domestic economy and resurgence of
Asian markets provided a backdrop for good performance in technology related
issues as well as the more cyclical basic industries. The best performing area
of the marketplace continued to be the largest and most growth oriented names,
which are predominately found in the technology sector. Continued low inflation
and the Fed's decrease in interest rates allowed investors to substantiate the
historically high valuations. The capitalization bias of this Fund moderated its
performance relative to the broad market as investors shied away from smaller
issues, with the exception of Internet related stocks.
      The Fund performed relatively well in comparison to the index for the past
year as industry weighting added value, which partially offset weak stock
selection. The Fund's overweight to the high growth industries of business
services, business machines, electronics and retail proved to be good decisions.
This helped offset poor stock specific decisions lead by holdings in Network
Associates, Waste Management, Office Depot and Rite Aid.
      Going forward the Fund will continue to provide mid-cap exposure within
the domestic equity marketplace. The fund maintains broad diversification across
all sectors and holds in excess of 100 names.

                 Adviser--SEI Investments Management Corporation
                    Sub-Adviser--STI Capital Management, N.A.

OBJECTIVE
      The Capital Appreciation Fund seeks to provide capital appreciation
through a diversified portfolio of common stocks. Dividend income is incidental
to the growth of capital. Securities are selected for the Fund based on factors
believed to be favorable for long-term appreciation, such as historical returns
on equity and earnings growth rates. Holdings in the Fund are rotated between
various market sectors based on economic analysis of the business cycle.

<PAGE>

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

STRATEGY
      The investment management process followed by the sub-adviser emphasizes
business cycle analysis, sector rotation and stock selection. The sub-adviser
identifies market sectors that appear undervalued and/or are outperforming other
sectors during a specific interval in the business cycle. The sub-adviser then
selects securities with a history of growth and a P/E ratio below comparable
companies in that market sector. Trading ranges are assigned for the prices of
these companies and these companies are actively traded while the sector remains
in favor. As a sector's favor changes over the business cycle, holdings are
shifted into the sectors showing the most potential for return.

ANALYSIS
      The Capital Appreciation Fund posted a 23.1% return for the fiscal year
ended September 30, 1999. The fund, and broad domestic equity market, managed
another year of strong gains bolstered by continued investor confidence, a
strong U.S. economy and a resurgence of economic prosperity in Asian economies.
      For the year large cap and growth oriented companies continued to lead the
market driven by a stronger than expected domestic economy and new business
opportunities globally. This was particularly true for the technology area of
the marketplace. Commodity stocks also enjoyed favorable returns in the past
year driven by prosperity in emerging markets and OPEC controls to oil
production worldwide. Smaller cap issues, with the exception of Internet stocks,
continued to lag the market due in part to their domestic orientation and also a
lack of attention from the investing marketplace.
      Returns within sectors were quite differentiated with higher growth
industries such as business machines, electronics, telephones and retail names
providing the market leadership. More value oriented or basic industries such as
chemicals, oil, energy and food stocks experienced much more moderate gains.
      The portfolio benefited from its industry weightings for the year by
remaining overweighted to the high growth areas of the market mentioned above
and limiting exposure to industries such as drugs, energy and food. Moderate
weakness was experienced from specific stock selection within retail and
business services names.
      The portfolio's largest weightings include healthcare, retail and
technology companies, with minor investments in utilities, capital goods and oil
companies. The portfolio is diversified across economic sectors and currently
holds more than 120 securities.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FUND PERFORMANCE
- --------------------------------------------------------------------------------
SEI Institutional Managed Trust -- September 30, 1999

                               Equity Income Fund
                 Adviser--SEI Investments Management Corporation
              Sub-Advisor--HighMark Capital Management, (previously
                           known as Pacific Alliance Capital Management)

OBJECTIVE
      The Fund seeks to provide current income and, as a secondary objective,
moderate capital appreciation through a diversified portfolio of common stocks.
The Fund invests in securities that have a high current yield and a low level of
volatility relative to the market while participating in rising markets.

STRATEGY
      The investment management process followed by the sub-adviser emphasizes
current income. The Fund is managed to provide a yield that is approximately 120
to 200 basis points above the yield on the S&P 500 Index. Securities that have
favorable long-term fundamental characteristics are selected for the Fund when
their current yields are at the upper end of their historic yield ranges. When
the price of a stock rises sufficiently to cause its yield to drop to the lower
end of this historic range, the security is a candidate to be sold. The yield of
a security might vary between its buy and sell range over a three or four year
cycle.

ANALYSIS
         The Equity Income Fund posted a 15.4% return for the fiscal year ended
September 30, 1999 as its search for yield and appetite for more defensive names
did not allow the portfolio to participate fully in the strong market returns.
      The best performing areas of the marketplace continued to be the largest
and most growth oriented names, which are predominately found in the technology
sector. Continued low inflation and the Fed's decrease in interest rates allowed
investors to substantiate the historically high valuations. Industry performance
was broadly positive as slower growth and more cyclical companies benefited from
an uptick in global demand.
      The portfolio lagged the index due to both stock specific and industry
weighting decisions. The fund's underweight to the technology area, and in
particular electronics and business machines, hurt. Additionally an overweight
to financial services companies hurt as they were unable to keep pace with
technology names. From a stock selection perspective the portfolio was hurt by
its valuation discipline which didn't allow investment in the highest growth
names in the business machines, electronics and retail industries.
      Going forward, the portfolio's diversification into mostly defensive
positions is expected to protect it from experiencing severe losses compared to
the market though it is not likely to fully participate in a strong market.

                                  Balanced Fund
                 Adviser--SEI Investments Management Corporation
                    Sub-Adviser--STI Capital Management, N.A.

OBJECTIVE
      The Balanced Fund seeks to achieve total return while preserving capital
by investing in a combination of common stocks and fixed income securities. By
altering the mix of equity and fixed income securities, the Fund seeks to
minimize losses during declining equity markets while realizing strong returns
in rising markets.

STRATEGY
      The manager views equities as the primary source of return in balanced
portfolios, with fixed income instruments primarily providing stability and
diversification. The Fund combines a core group of demonstrated growth stocks
with securities selected through business cycle analysis and sector rotation.
This approach tends to result in a fund of large capitalization stocks with
price-to-earnings ratios, growth rates and returns on equity higher than the
market averages. Fixed income selection attempts to provide fund stability and
incremental return by identifying inexpensive areas of the yield curve and
improving corporate credits.

ANALYSIS
      The Balanced Fund posted an 11.2% return for the fiscal year ended
September 30, 1999. Once again equities lead fixed income securities due in
large part to continued strength in the domestic economy and better than
expected economic growth internationally. For most of the year the fixed income
portfolio benefited from declining interest rates driven by Fed rate changes.
      For the year large cap and growth oriented companies continued to lead the
market driven by a stronger than expected domestic economy and new business
opportunities globally. This was particularly true for the technology area of
the marketplace. Commodity stocks also enjoyed positive returns in the past year
driven by prosperity in emerging markets and OPEC controls to oil production
worldwide. Smaller cap issues, with the exception of Internet stocks, continued
to lag the market due in part to their domestic orientation and also a lack of
attention from the investing marketplace.
      Returns within sectors were quite differentiated with higher growth
industries such as business machines, electronics, telephones and retail names
providing the market leadership. More value oriented or basic industries such as
chemicals, oil, energy and food stocks experienced much more moderate gains.
      The portfolio successfully managed to mitigate volatility from the
marketplace by investing in large domestic equities along with conservative
fixed income investments. The Balanced Fund continues to maintain
diversification across sectors and holdings in excess of 120 securities.

                                                                              11

                 Adviser--SEI Investments Management Corporation
                 Sub-Advisers--Western Asset Management Company
                               Firstar Investment Research &
                                Management Company, L.L.P.
                               BlackRock Financial Management, Inc.

OBJECTIVE
      The Core Fixed Income Fund seeks to provide current income consistent with
the preservation of capital by investing in a diversified portfolio of fixed
income securities while also limiting fluctuations in principal value. The Fund
invests in every sector of the fixed income universe, including Treasuries,
agencies, mortgage-backed issues, investment-grade corporates, and Yankee bonds.

STRATEGY
      With respect to this Fund, SEI Investments Management Corporation employs
a multi-manager structure. The sub-advisers' investment strategies focus 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 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
      The Core Fixed Income Fund posted an -0.96% return for the fiscal year
ended September 30, 1999, underperforming the Lehman Aggregate Bond Index return
of -0.37 % over the same period. The U.S. Treasury market had a difficult year
and ended the fiscal period with interest rates 1% to 1.5% higher. The fiscal
year opened with interest rates at very low levels following a flight-to-safety
rally amid significant market turmoil. Responding to the global financial
crisis, the Fed had previously eased rates by 0.25% and the market had priced in
several more rate reductions. As the crisis subsided and investors moved out of
U.S. Treasuries and into other assets, interest rates began to rise. Interest
rates rose in every quarter of the fiscal year. Accommodative monetary policy
and excess global capacity supported strong growth in the U.S. in the early
months of 1999. In May, bond yields rose sharply in response to higher than
expected domestic growth and concerns that inflationary pressures were building.
This prompted two Fed rate hikes during the summer.

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

      In an environment of rising interest rates, the Fund's longer duration
posture, maintained between 105% and 110% of benchmark exposure throughout the
period, detracted from performance. However, the Fund's underweight to
intermediate term issues helped returns as intermediate term interest rates rose
by nearly twice as much as longer and shorter term yields.
      Spreads in the corporate and mortgage markets moved dramatically over the
fiscal year. The funds overweight position in the corporate and mortgage sectors
benefited performance for the year as these sectors outperformed Treasuries on a
duration-adjusted basis. During the first part of the year, spreads narrowed as
stabilization in the global economic picture and robust growth in the U.S.
attracted investors to the extra yield offered by corporate bonds and mortgage
backed securities. However, during the later part of the year spreads suffered
due to the combination of robust new issuance in the corporate market and fears
of Fed rate hikes. In September of 1999, when the deluge of new corporate
issuance failed to materialize, spreads began to contract. The Fund began the
year with a modest overweight to corporate and mortgage spreads and increased
that overweight position as spreads widened into the summer of 1999. Overall the
Fund's sector positioning helped Fund returns.
      During the first part of the fiscal year, lower quality investment grade
credits outperformed but later in the year these credits underperformed as
liquidity concerns weighed. The Fund's overweight to lower quality investment
grade credits hurt relative performance. Security selection contributed to
overall fund performance, reflecting manager skill in finding relative value
opportunities.

                                  Asset Management

OBJECTIVE
      The High Yield Bond Fund seeks to maximize total return by investing
primarily in a diversified portfolio of higher yielding, lower rated fixed

through sector rotation and security selection.

STRATEGY
      Fund strategy is to identify high yield market sectors and securities that
offer investment opportunities through the analysis of macro-

                                                                              13

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FUND PERFORMANCE

SEI Institutional Managed Trust -- September 30, 1999

economic, interest rate, industry, and technical factors. Those companies that
are best suited to benefit from the identified trends are then selected for
investment. Risk is controlled through a high level of diversification, and by
performing detailed and ongoing credit analysis on the companies considered and
purchased.

ANALYSIS
      The High Yield Bond Fund posted a 3.51% return for the fiscal year ended
September 30, 1999.
      Effective 12/31/98, the CS First Boston (CSFB) Domestic Plus High Yield
Index replaced the CS First Boston Global High Yield Index as the benchmark for
the SIMT High Yield Fixed Income Fund. The new CSFB Domestic Plus High Yield
Index is a sub-sector of the existing CSFB Global High Yield Index, and includes
primarily U.S. issuance and G7+ country issuance that is U.S. dollar
denominated. The exclusion of emerging market corporate debt is the only
differentiating characteristic of the domestic index versus the global index.
      Nomura Corporate Research and Asset Management was added as an additional
sub-adviser to the Fund at the close of the year. Nomura Corporate Research and
Asset Management emphasizes a research-intensive, bottom-up approach to identify
fundamentally strong and quality companies. The addition of Nomura is expected
to compliment the Fund's existing top-down style, thus enhancing the overall
risk/return profile of the Fund. The Fund will maintain a 70% allocation to
Credit Suisse Asset Management and a 30% allocation to Nomura Corporate Research
and Asset Management. These allocations are targeted to be fully implemented by
the second quarter of 2000.
      Despite a come back in the market for the majority of the fiscal year,
mounting concern over higher interest rates and sustained liquidity in the
marketplace reversed earlier period positive momentum. The aura of uncertainty
in the global markets that had plagued investors for some time dwindled during
the year amid signs of economic recovery in Southeast Asia and a healthy
European economy. Unfortunately, the high yield market could not maintain its
positive momentum and lost ground at the end of the year. Bearish market
sentiment evolved as interest rates inched upward in the U.S., and cash inflows
decreased and subsequently turned negative coupled with constrained
broker-dealer liquidity. Liquidity constraints surfaced due to broker-dealers
still stunned by previous period losses that occurred as a result of the Asian
and Russian crises, and concerns over year-end and Y2K. Also weighing down the
market was evidence of increasing defaults and negative sector-specific events.
Volatility remained a consistent characteristic in the market, and through out
the period, the market was forced to battle increased volatility. However, all
was not gloom for the market. Higher commodity prices served to lift
commodity-related sector returns such as energy, and paper and packaging, while
merger and acquisition (M&A) activity dominated the telecommunication, cable,
and gaming sectors and helped to support prices in these sectors. Spreads
narrowed somewhat during the year, but still remained wide relative to the
rolling 10-year average. A more risk-averse investor profile and tightened
liquidity left the high yield market spread, relative to the 10-year Treasury,
at 607 basis points at the close of the period.

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

      For the most part, performance of the Fund was a story of what the Fund
did not own versus what it did own during the year! This was particularly seen
in the general industrial sector where the Fund's positive security selection
greatly benefited return. Within the mobile communications sector, M&A activity
positively contributed to performance complimented by an underweight to
satellite and paging issues. The satellite sector came under pressure as
companies such as Iridium and ICO Global defaulted on their debt obligations.
Paging issues drifted downward in price amid stepped-up competition and
lower-than expected earnings.
      The Fund's underweight to the healthcare sector and long-term care
securities also bolstered return. The healthcare sector posted the worst
performance for the year. Long-term care securities pulled down returns within
the overall sector due to unfavorable regulatory changes in U.S. Medicare
reimbursement practices.
      Merger and acquisition activity in the fixed telecom sector also served to
enhance return of the Fund. As a whole, the telecom sector benefited from
favorable M&A activity, and the Fund's holdings in issues such as Sprint
Spectrum, IXC Communications, and Global Crossing that were either acquired, or
merged, with other companies during the year lifted return.
      Within the gaming sector, continued consolidation in the casino industry,
in addition to strong gaming revenues, served to bolster the Fund's return. An
underweight to Atlantic City issues and a focus on off-strip Las Vegas and
emerging, or non-Las Vegas, issues credits was a plus.
      The Fund's underweight to the paper and packaging sector, and in
particular paper-related issues, dampened performance somewhat. As the global
economy began to recover, thus serving as a catalyst for improved commodity
prices, the paper and packaging sector performed exceptionally well. This strong
performance was most predominant in the fourth quarter of 1998. This sector had
been severely distressed for some time through out 1997 and 1998 and was poised
for a rebound. Given the strength in commodity prices, the Fund has begun to
increase its exposure to paper-related issues.
      Consistent with the positive trend in the global economy and commodities,
in addition to diminished supply, oil prices rebounded throughout 1999. Energy
companies held by the Fund did not benefit from rallying oil prices, and this
negatively impacted return.
      Given near-term uncertainty and an unstable market environment, the Fund
will continue to focus on more liquid and fundamentally sound sectors and
securities.

SEI Institutional Managed Trust -- September 30, 1999

1. Organization

     SEI Institutional Managed Trust (the "Trust") is organized as a
Massachusetts Business Trust under a Declaration of Trust dated October 20,
1986. The Trust is registered under the Investment Company Act of 1940, as
amended, as an open-end investment company with eleven diversified Funds (the
"Funds"): Large Cap Value, Large Cap Growth, Tax-Managed Large Cap, Small Cap
Value, Small Cap Growth, Mid-Cap, Capital Appreciation, Equity Income, Balanced,
Core Fixed Income, and High Yield Bond. The Trust is registered to offer Class A
shares of the Large Cap Value, Large Cap Growth, Small Cap Value, Small Cap
Growth, Mid-Cap, Capital Appreciation, Equity Income, Balanced, Core Fixed
Income, and High Yield Bond Funds and Class D shares of the Small Cap Growth
Fund. The Funds' prospectus provides a description of each Funds' investment
objective, policies, and strategies.

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 which 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. 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 at fair
value using methods determined in good faith 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. 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 agreement and procedures
adopted by the Manager and the Advisers of the Trust require that the market
value of the collateral, including accrued interest thereon, is sufficient in
the event of default by the counterparty. If the counterparty defaults and the
value of the collateral declines or if the counterparty enters into an
insolvency proceeding, realization of the collateral by the Funds may be delayed
or limited.
     Compensating Balances--Funds with cash overdrafts in excess of $100,000 are
required to leave 112% in compensating balance with First Union, the custodian
of the Trust, on the following day. Funds with positive cash balances in excess
of $100,000 are allowed to overdraw 90% of the balance with First Union on the
following day.
     Discount and Premium Amortization--Amortization and accretion 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.
     Classes--Class-specific expenses are borne by that class of shares. Income,
realized and unrealized gains/losses and non class-specific expenses are
allocated to the respective classes on the basis of relative daily net assets.
     Futures Contracts--The Large Cap Growth, Large Cap Value, Tax-Managed Large
Cap, Small Cap Value, Small Cap Growth, Capital Appreciation and
                                                                              81

NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------
SEI Institutional Managed Trust -- September 30, 1999

Equity Income Funds utilized S&P 500 Index futures contracts and the Core Fixed
Income Fund utilized U.S. Long T-Bond and five and ten year note futures
contracts during the period ended September 30, 1999. The Funds' investment in
S&P 500 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 the counterparty to a contract may default on its
obligation to perform. Futures contracts involve risk of loss in excess of the
amounts recognized in the Statement of Net Assets to the extent of the contract
amounts.
     Option Selling/Purchasing -- Each Fund may invest in financial options
contracts solely for the purpose of hedging its existing fund 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 or
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.
     Restricted Securities--Certain of the Fund's investments are restricted as
to resale. The table below shows the number of shares held, the acquisition
date, cost, market value as of September 30, 1999, value per share of such
securities and percentage of net assets which the securities comprise:

     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.
     The Large Cap Value, Large Cap Growth, Tax-Managed Large Cap, and Small Cap
Growth Funds utilized earnings and profits distributed to shareholders on
redemption of shares as a part of the dividends paid deduction for income tax
purposes.
     Other--Security transactions are recorded on the trade date of the security
purchase or sale. Costs 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.

up to .25% of average daily net assets attributable to Class A shares will be
paid to the Distributor.
     The Trust has adopted a distribution plan for its Class D shares (the
"Class D Plan") pursuant to which a 12b-1 fee of up to .30% of the average daily
net assets attributable to the Class D shares will be paid to the Distributor.
This payment may be used to compensate financial institutions that provide
distribution-related services to their customers. Under both the Class A Plan
and the Class D Plan, the Distributor may retain as profit any difference
between the fee it receives and the amount it pays to third parties.
     The Distribution Agreement between the Distributor and the Trust provides
that the Distributor may receive compensation on fund transactions effected for
the Trust in accordance with the rules of the Securities and Exchange Commission
("SEC").

Accordingly, it is expected that fund transactions may result in brokerage
commissions being paid to the Distributor. The SEC rules require that such
commissions not exceed usual and customary commissions.

4. Transactions with Affiliates

     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.

     Each of the 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. Aggregate commissions paid by the Trust for
repurchase agreements placed during the period ended September 30, 1999 were
$197,206.

5. Investment Transactions
