MANAGEMENT'S DISCUSSION AND ANALYSIS OF FUND PERFORMANCE
SEI INSTITUTIONAL MANAGED TRUST -- SEPTEMBER 30, 2007

Large Cap Value Fund

Objective

The Large Cap Value Fund (the "Fund") seeks to provide long-term growth of
capital and income by investing in the equity securities of large companies. The
Fund invests primarily in a diversified portfolio of high quality, income
producing common stocks, which in the adviser's opinion, are undervalued in the
marketplace at the time of purchase.

Strategy

With respect to this Fund, SEI Investments Management Corporation ("SIMC")
employs a multi-manager structure to gain exposure to the entire large cap value
sector, adding value through stock selection while managing risk in the form of
capitalization, valuation and economic sector exposures. Assets of the Fund are
strategically allocated among its four 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 sub-style to the Fund. Aronson + Johnson + Ortiz invests in
asset-rich companies selling at relatively low multiples of earnings which have
earnings and price momentum. LSV Asset Management invests in companies trading
at deep discounts to their intrinsic value, while Enhanced Investment
Technologies employs a volatility capture strategy. AllianceBernstein
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.

Analysis

The Large Cap Value Fund, Class A, returned 13.91% for the fiscal year, lagging
behind the value area of the market for the period. The Russell 1000 Value Index
returned 14.45% for the fiscal year ended September 30, 2007.

U.S. large cap stocks rallied strongly during the fiscal year returning close to
17% for the one year ending September 30, 2007 as measured by the Russell 1000
Index. Investors were encouraged by strong global economic growth and seemed to
adjust well to slowing growth in the U.S. following record double digit growth
for multiple prior quarters. The rally came in spite of rising oil prices to
above $80 a barrel as well as weakness in housing and ongoing subprime fears.
The fiscal year started out on a strong note as large cap stocks rallied for the
first several months on strong global economic news, low unemployment and a
continued torrid pace of merger and acquisition and private equity activity.
Investors pushed through a temporary setback in late February when the market
fell by 3.5% in a single day. Subprime fears came to a head in late July and
early August, when credit markets seized up and spilled over into equity markets
sending the broader market down close to 10% from the mid-July peaks to
mid-August. This market weakness tended to hit quantitative managers the hardest
due to what we believe to be a shift in capital market flows and hedge fund
trading. Once again, however, markets regained their footing as global central
banks injected liquidity into financial markets, and investors began to price in
a 25 basis points or 50 basis points rate cut by the U.S. Federal Reserve. By
the end of September, markets were once again approaching new highs.

The energy and materials sectors continued to lead markets as both returned
approximately 40% for the fiscal year. Energy rallied on the back of strong oil
prices and heightened supply concerns. The financials sector was the significant
underperformer; weighed down by subprime fallout. Thrifts and mortgage finance,
consumer finance, as well as the large money center banks were among the weakest
performers. The fiscal year witnessed the reversal of two significant and
long-running trends in the U.S. equity market: the underperformance of growth
and the underperformance of megacaps. The Russell 1000 Growth Index outpaced the
Russell 1000 Value Index by close to 5% as both stronger growing and more
expensive stocks, as measured by P/E, outperformed. Although the largest 10% and
20% of the stock universe performed slightly below the broad market for the
entire fiscal year, these stocks staged a sharp comeback starting in the third
fiscal quarter.

The portfolio outpaced the benchmark for the first three quarters of the fiscal
year, but gave back much of the gains following the spillover from the credit
meltdown in July and August. On the positive side, the portfolio benefitted from
strong stock selection within the information technology, industrials and
consumer staples sectors. The portfolio also benefitted from a slight overweight
to faster growing stocks in the value benchmark. However, this was offset by the
negative impact of a slight overweight to diversified financials as well as
negative stock

selection within thrifts and mortgage finance companies. All four sub-advisers
to the fund traded fairly close to the Russell 1000 Value Index benchmark with
the exception of LSV Asset Management. LSV Asset Management outpaced the value
area of the market as the manger's strong stock selection within the industrials
and information technology sectors more than offset negative stock selection
within the financials sector.

There were no sub-adviser changes during the fiscal year.

      10/3/94 at which time Mellon Equity Associates acted as investment adviser
      to the Fund. Previous periods during which the Fund was advised by another
      investment adviser are not shown. Class I Shares performance for the
      period prior to 8/6/01 is performance derived from the performance of the
      Class A Shares. The performance of Class I Shares may be lower than the
      performance of Class A Shares because of different distribution fees paid
      by Class I shareholders. Class A Shares were offered beginning 10/3/94 and
      Class I Shares were offered beginning 8/6/01. Returns shown do not reflect
      the deduction of taxes that a shareholder would pay on fund distributions
      or the redemption of fund shares. The returns for certain periods reflect
      fee waivers and/or reimbursements in effect for that period; absent fee
      waivers and reimbursements, performance would have been lower.

SEI INSTITUTIONAL MANAGED TRUST -- SEPTEMBER 30, 2007

Large Cap Growth Fund

Objective

The investment objective of the Large Cap Growth Fund (the "Fund") is capital
appreciation by investing in the equity securities of large companies. The Fund
invests in the securities of issuers believed to possess significant growth
potential that is underappreciated by the market.

Strategy

With respect to this Fund, SEI Investments Management Corporation ("SIMC")
employs a multi-manager structure to gain exposure to the entire large cap
growth sector, adding value through stock selection while managing 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. Goldman Sachs Asset Management invests in companies with
strong business franchises that are attractively priced relative to their
discounted cash flows. Quantitative Management Associates favors large cap
stocks that have positive news flow and attractive valuation characteristics.
Montag & Caldwell invests in large cap stocks that exhibit accelerating
earnings, are trading at a discount to fair value, and are financially stable.
Enhanced Investment Technologies employs a volatility capture strategy, while
Delaware Management Company invests in stocks that are attractively valued from
a cash flow basis and have strong prospects for organic growth in the future.

Analysis

The Large Cap Growth Fund, Class A, returned 19.26% for the fiscal year, lagging
behind the growth area of the market for the period. The Russell 1000 Growth
Index returned 19.35% for the fiscal year ended September 30, 2007.

U.S. large cap stocks rallied strongly during the fiscal year returning close to
17% for the one year ending September 30, 2007 as measured by the Russell 1000

entire fiscal year, these stocks staged a sharp comeback starting in the third

The portfolio benefited from having a more significant growth exposure than the
benchmark as well as strong stock selection across sectors. Stock selection was
particularly strong within health care, technology and diversified financials.
The energy sector also

presented a boost as the managers tended to favor the outperforming oil services
and equipment companies that they believe will benefit the most from the
increased global energy demand and limited supply. The most notable detractors
to relative performance were underweight positions to the industrials and
materials sectors which both rallied during the fiscal year. The portfolio also
had a modest overweight to the food retailing industry that lagged the broad
market.

Montag & Caldwell performed very well for the period driven by strong stock
selection within the energy and information technology sectors. Quantitative
Management Associates lagged the growth benchmark as the sub-portfolio sold off
late in the fiscal year following the flight to quality while Enhanced
Investment Technologies suffered from an environment of relatively low
volatility. Lastly, Delaware Management Company and Goldman Sachs Asset
Management outpaced the growth benchmark.

There were no sub-adviser changes during the fiscal year.

Tax-Managed Large Cap Fund

Objective

The investment objective of the Tax-Managed Large Cap Fund (the "Fund") is
capital appreciation by investing in the equity securities of large companies.
The Fund attempts to maximize after-tax returns to investors through lower
turnover and tax management techniques.

Strategy

With respect to this Fund, SEI Investments Management Corporation ("SIMC")
employs a multi-manager structure to gain exposure to the entire U.S. large cap
market, seeking to add 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. Goldman Sachs Asset Management, Delaware Management, and
Montag & Caldwell focus on stocks that have growth characteristics.
AllianceBernstein, LSV Asset Management and Aronson + Johnson + Ortiz focus on
selecting stocks that have value-oriented characteristics. Quantitative
Management Associates invests a core portfolio that favors large cap stocks with
positive news flow trading at attractive valuations. Parametric Portfolio
Associates invests in both value and growth large-cap stocks through a
quantitative process which aggressively harvests tax-losses in the portfolio.

Analysis

The Tax-Managed Large Cap Fund, Class A, returned 17.05% for the fiscal year,
finishing ahead of the broad market for the period. The Russell 1000 Index
returned 16.90% for the fiscal year ended September 30, 2007.

U.S. large cap stocks rallied strongly during the fiscal year returning close to
17% for the one year ending September 30, 2007 as measured by the Russell 1000
Index. Investors were encouraged by strong global economic growth and seemed to
adjust well to slowing growth in the U.S. following record double digit growth
for multiple prior quarters. The rally came in spite of rising oil prices to
above $80 a barrel as well as weakness in housing and ongoing subprime fears.
The fiscal year started out on a strong note as large cap stocks rallied for the
first several months on strong global economic news, low unemployment and a
continued torrid pace of merger and acquisition and private equity activity.
Investors pushed through a temporary setback in late February when the market
fell by 3.5% in a single day. Subprime fears came to a head in late July and
early August, when credit markets seized up and spilled over into equity markets
sending the broader market down close to 10% from the mid-July peaks to
mid-August. This market weakness tended to hit quantitative managers the hardest
due to what we believe to be a shift in capital market flows and hedge fund
trading. Once again, however, markets regained their footing as global central
banks injected liquidity into financial markets, and investors began to price in
a 25 basis points or 50 basis points rate cut by the U.S. Federal Reserve. By
the end of September, markets were once again approaching new highs.

The energy and materials sectors continued to lead markets as both returned
approximately 40% for the fiscal year. Energy rallied on the back of strong oil
prices and heightened supply concerns. The financials sector was the significant
underperformer; weighed down by subprime fallout. Thrifts and mortgage finance,
consumer finance, as well as the large money center banks were among the weakest
performers. The fiscal year witnessed the reversal of two significant and
long-running trends in the U.S. equity market: the underperformance of growth
and the underperformance of megacaps. The Russell 1000 Growth Index outpaced the
Russell 1000 Value Index by close to 5% as both stronger growing and more
expensive stocks, as measured by P/E, outperformed. Although the largest 10% and
20% of the stock universe performed slightly below the broad market for the
entire fiscal year, these stocks staged a sharp comeback starting in the third
fiscal quarter.

The Fund benefited from having a more significant growth exposure than the
benchmark as well as strong stock selection across sectors. Stock selection was
particularly strong within information technology, energy and diversified
financials. Strength within the energy sector was driven by overweight positions
in the outperforming oil services and equipment companies that the managers
generally believe will benefit the most from the increased global energy demand
and

limited supply. The most notable detractors to relative performance were
underweight positions to the industrials and materials sectors which both
rallied during the fiscal year. The portfolio also had a modest overweight to
thrifts and mortgage finance companies as well as diversified financial
companies which weighed on performance.

The growth managers in the Fund strongly outpaced the growth benchmark while the
value managers traded modestly ahead of the value area of the market. The one
standout is Montag & Caldwell, whose strong performance during the period was
driven by stock selection within the energy and information technology sectors.

During the fiscal year, SIMC added Quantitative Management Associates as a
sub-adviser to the portfolio.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FUND PERFORMANCE
SEI INSTITUTIONAL MANAGED TRUST -- SEPTEMBER 30, 2007

Large Cap Diversified Alpha Fund

Objective

The Large Cap Diversified Alpha Fund (the "Fund") seeks to provide long-term
growth of capital and income by investing in the equity securities of large
companies and in portfolio strategies designed to correlate to a portfolio
composed of large cap equity securities. While the Fund is expected to have an
absolute return and risk profile similar to the broad U.S. large cap equity
market, returns may be derived in part from investing significant portions of
the Fund in securities outside of the large cap market.

Strategy

The Fund uses a multi-manager approach under the general supervision of SEI
Investments Management Corporation ("SIMC"), allocating the assets among
multiple sub-advisers that use different investment strategies to seek to
achieve returns in excess of the performance of a broad U.S. large cap
benchmark. This allocation among investment strategies aims to diversify the
sources from which sub-advisers seek to achieve excess returns (i.e., returns in
excess of a benchmark index), and thereby diversify the relative risk of the
Fund.

Some sub-advisers may engage in short sales up to 30% of the value of their Fund
allocation and use the proceeds from the sale to purchase long positions in
additional equity securities. Some sub-advisers may also use portfolio
strategies that are designed to correlate with a portfolio of large cap equity
securities, but which are composed of derivative instruments backed by other
types of securities.

Aronson + Johnson + Ortiz, Analytic Investors, and Quantitative Management
Associates seek to overweight stocks with attractive fundamental and/or
technical characteristics and underweight or even short stocks with unattractive
fundamental and/or technical characteristics. Enhanced Investment Technologies
employs a volatility capture strategy, Delaware Management Company seeks to
identify stocks with underappreciated growth characteristics, while Smith
Breeden Associates seeks to generate excess returns within the U.S. fixed income
market and transports it to the equity market.

Analysis

The Large Cap Diversified Alpha Fund, Class A, returned 15.64% for the fiscal
year ending September 30, 2007, trailing the broad market. The Russell 1000
Index returned 16.90% for the fiscal year ended September 30, 2007.

U.S. large cap stocks rallied strongly during the fiscal year returning close to
17% for the one year ending September 30, 2007 as measured by the Russell 1000
Index. Investors were encouraged by strong global economic growth and seemed to
adjust well to slowing growth in the U.S. following record double digit growth

above $80 a barrel as well as weakness in housing and ongoing subprime fears.

and long-running trends in the U.S. equity market: the underperformance of
growth and the underperformance of megacaps. The Russell 1000 Growth Index
outpaced the Russell 1000 Value Index by close to 5% as both stronger growing
and more expensive stocks, as measured by P/E, outperformed. Although the
largest 10% and 20% of the stock universe performed slightly below the broad
market for the entire fiscal year, these stocks staged a sharp comeback starting
in the third fiscal quarter.

The Fund suffered from exposure to the fixed income markets through the Smith
Breeden Associates portable alpha strategy. Although Smith Breeden's portfolio
was generally higher quality with very limited exposure to the subprime area of
the market, the credit crunch that started in July was very broad and few areas
of the bond market were spared. The portfolio also suffered from an underweight
to the rallying energy sector. On the positive side, the portfolio benefited
from being underweight financials as well as strong stock selection across
sectors. Stock selection was particularly strong within materials, health care,
and diversified financial services.

From an individual manager standpoint, Enhanced Investment Technologies,
Quantitative Management Associates, and Smith Breeden Associates fell short of
the broad market, while Analytic Investors, Aronson + Johnson + Ortiz, and
Delaware Management outpaced their respective benchmarks. Analytic Investors
performed particularly well benefiting from their factor momentum investment
strategy.

There were no sub-adviser changes during the fiscal year.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FUND PERFORMANCE
SEI INSTITUTIONAL MANAGED TRUST -- SEPTEMBER 30, 2007

S&P 500 Index Fund

Objective

The S&P 500 Index Fund (the "Fund") seeks to provide investment results that
correspond to the aggregate price and dividend performance of the securities in
the S&P 500 Index (the "Index"). The Index is a capitalization-weighted index of
500 stocks intended to be a representative sample of leading companies in
leading industries within the U.S. economy. Stocks in the Index are chosen for
market size (large-cap), liquidity, and industry group representation.

Strategy

The Fund attempts to match the performance of the widely followed Index by
replicating its composition in full. The fifty largest stocks in the Index
account for approximately 50% of the weighting of the Index. Deviation of
performance between the Fund and the Index, measured as tracking error, is
typically attributable to trading costs and cash reserves held for liquidity
needs. The presence of cash in the Fund may result in underperformance relative
to the Index in rising markets and out-performance in declining markets. To
mitigate these effects, the Fund may use stock index futures to hedge its cash
position. Futures contracts enable the Fund to maintain exposure to the market
with reduced trading expenses, since the cost of the futures contract is
relatively nominal. The value of stock index futures held by the Fund may not
exceed 20% of the Fund's assets.

Analysis

The S&P 500 Index Fund, Class A, returned 16.04% for the fiscal year. For the
fiscal year ending September 30, 2007, the Index posted double digit gains,
returning 16.44%. During the period, large cap securities outperformed their
small cap counterparts but trailed non-U.S. securities. Growth oriented stocks
led their value counterparts. In mid-July and August, the market suffered a bit
of a liquidity crunch as subprime meltdown in fixed income trickled into the
equity markets. The U.S. Federal Reserve cut the federal fund rate by 50 basis
points, which benefited the equity markets.

All ten S&P GICS sectors generated positive returns during the fiscal year.
Materials and energy were two of the best performing sectors. Meanwhile,
financials, health care, and consumer discretionary stocks trailed the rest of
the market. Overall, the financials sector was the worst performing sector
during the fiscal year.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FUND PERFORMANCE
SEI INSTITUTIONAL MANAGED TRUST -- SEPTEMBER 30, 2007

Small Cap Value Fund

Objective

The Small Cap Value Fund (the "Fund") seeks to provide capital appreciation by
investing in equity securities of smaller companies. The Fund invests in the
stocks of companies it believes are undervalued in light of such fundamental
characteristics as earnings, book value or return on equity.

Strategy

With respect to this Fund, SEI Investments Management Corporation ("SIMC")
employs a multi-manager structure to gain exposure to the entire small cap value
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 nine investment managers. Assets of the Fund are strategically
allocated among its eight 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. Using a bottom-up process, Artisan Partners
Limited Partnership seeks to identify companies which are currently trading
below the intrinsic value of the business that have little institutional
following. BlackRock Capital Management focuses on attractively valued companies
with a near term business catalyst. David J. Greene and Company invests in
complex multi-segment businesses often possessing several growth areas masked by
a slower growing parent. Lee Munder Investments uses a classic value approach of
identifying quality businesses at attractive valuations. LSV Asset Management
invests in companies trading at deep discounts to their intrinsic value and near
term earnings visibility. Martingale Asset Management employs a systematic
approach focused on relative valuation, sustainable growth, and management
quality. Wellington Management Company utilizes a unique risk/reward relative
valuation assessment to identify attractive real estate investments. Weiss, Peck
& Greer seeks to exploit market anomalies through both traditional value
investments and special situations, investing when a near-term, positive
catalyst exists at company and sector levels. Each of the aforementioned
sub-styles assumes a different importance in determining overall style risk and
must therefore be weighted accordingly.

Analysis

The Russell 2000 Value Index (the "Index") yielded 6.09% for the fiscal year
ending September 30, 2007. Materials were the biggest contributor to the
performance of the Index over the past year, posting excellent returns on
climbing commodity prices amid growing global demand. Beginning in early 2007,
financials stocks experienced a substantial drop in performance: banks suffered
as investors became concerned over credit risk on subprime residential loans,
and REITs gave back most of their fourth quarter 2006 gains as the housing
market slowed. Consumer discretionary stocks, especially those in retailing,
lagged the Index for the period as investors worried about consumer spending in
the face of tighter credit conditions and rising gas prices.

The Small Cap Value Fund, Class A, gained 10.70% in the last 12 months, and five
of the managers surpassed the benchmark. Strong stock selection across sectors
and a strategic underweight to the lagging financials area boosted Fund returns
above the broad market. On a manager level, David J. Greene and Company beat the
broad market largely through superior stock selection in the industrials area,
and Lee Munder Investments performed the same feat with respect to information
technology and consumer discretionary. LSV Asset Management managed slight
excess returns over the fiscal year, despite struggling in the third quarter of
2007 as many valuation metrics exhibited negative returns. The excess returns
Martingale Asset Management accumulated from October 2006 through June 2007
could not offset the losses in early August as several large hedge fund managers
placed selling pressure on valuation-sensitive stocks which these managers
typically hold. Finally, Wellington Management Company's outperformance versus
the WRESI Index was due to strong and broad stock selection within REIT
securities.

During the fiscal year, SIMC added Weiss, Peck & Greer, LLC as a sub-adviser to
the portfolio.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FUND PERFORMANCE
SEI INSTITUTIONAL MANAGED TRUST -- SEPTEMBER 30, 2007

Small Cap Growth Fund

Objective

The Small Cap Growth Fund (the "Fund") seeks to provide long-term capital
appreciation by investing in equity securities of smaller companies. The Fund
invests in the stocks of companies that have significant growth potential in
light of such characteristics as revenue and earnings growth and positive
earnings surprises.

Strategy

With respect to this Fund, SEI Investments Management Corporation ("SIMC")
employs a multi-manager structure to gain exposure to the entire universe of
small cap growth stocks, 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 eight investment managers. Assets of the Fund are
strategically allocated among its seven 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. Mazama Capital Management invests primarily
in stocks entering extended periods of growth not yet understood by the market.
Wellington Management Company focuses on companies that demonstrate growth at
reasonable prices. Delaware Management Company focuses on companies with
sustainable growth models that are attractively valued. Lee Munder Investments
seeks companies growing faster than the market while demonstrating skill in
their ability to differentiate an attractive stock from a good company. McKinley
Capital Management emphasizes acceleration of the growth rate of companies
relative to the market's expectations and companies with positive earnings
surprises. Martingale Asset Management employs a systematic approach focused on
relative valuation, sustainable growth, and management quality. PanAgora Asset
Management provides broad coverage over the investment universe by applying
disciplined processes in which each stock is given a unique weighting to factors
such as growth, value, and beta. The stocks are then evaluated based on their
unique factor weightings and the performance of those and other factors in the
marketplace. Each of the aforementioned sub-styles assumes a different
importance in determining overall style risk and must therefore be weighted
accordingly.

Analysis

For the 12 months ending September 30, 2007, the Russell 2000 Growth Index (the
"Index") gained 18.94%. The information technology sector was the biggest
contributor to the performance of the Index over the past year: significant
merger and acquisition activity and increased corporate capital expenditures on
software and services boosted returns. The materials and utilities sectors both
posted excellent returns on climbing commodity prices amid growing global
demand. Beginning in early 2007, financials stocks experienced a substantial
drop in performance: banks suffered as investors became concerned over credit
risk on subprime residential loans, and REITs gave back most of their fourth
quarter 2006 gains as the housing market slowed. Many consumer discretionary
stocks, especially those in retailing, lagged the Index for the period as
investors worried about consumer spending in the face of tighter credit
conditions and rising gas prices.

The Small Cap Growth Fund, Class A, posted returns of 18.05% over the last 12
months. Positive stock selection in the consumer discretionary sector was
mitigated by securities in the health care and information technology areas.
Four of the growth managers, outperformed the broad market. Lee Munder
Investments exhibited excellent security selection in the information technology
and industrials sectors, allowing it to achieve excess returns. An overweight to
the metals and mining industry helped Wellington Management Company to beat the
broad market, and McKinley Capital Management's exposure to high price momentum
stocks lifted its returns above the benchmark. Quantitative managers PanAgora
Asset Management and Martingale Asset Management lagged the Index following a
difficult summer in 2007 during which hedge fund managers had placed selling
pressure on valuation-sensitive stocks which these managers typically hold.

During the fiscal year, SIMC added PanAgora Asset Management as a sub-adviser to
the portfolio.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FUND PERFORMANCE
SEI INSTITUTIONAL MANAGED TRUST -- SEPTEMBER 30, 2007

Tax-Managed Small Cap Fund

Objective

The investment objective of the Tax-Managed Small Cap Fund (the "Fund") is
capital appreciation by investing in the equity securities of small companies.
The Fund attempts to maximize after-tax returns to investors through investing
in undervalued securities, selling stocks with the highest tax cost first and
offsetting losses with gains where possible.

Strategy

With respect to this Fund, SEI Investments Management Corporation ("SIMC")
employs a multi-manager structure to gain exposure to the entire small/mid cap
universe, 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 eight investment managers. Assets of the Fund are strategically
allocated among the eight 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. BlackRock Capital Management focuses on
attractively valued companies with a near-term business catalyst. David J.
Greene and Company looks for undervalued securities that are misunderstood by
the marketplace. Delaware Management Company focuses on sustainable business
models at attractive valuations. LSV Asset Management disciplined proprietary
screening model ranks stocks based on price to book, price to cash flow, past
sales performance, and likelihood of near-term appreciation. Mazama Capital
Management invests primarily in stocks entering extended periods of growth not
yet understood by the market. McKinley Capital Management emphasizes
acceleration of the growth rate of companies relative to the market's
expectations and companies with positive earnings surprises. Parametric
Portfolio Associates invests in both value and growth small-cap stocks through a
quantitative process which aggressively harvests tax-losses in the portfolio.
Los Angeles Capital Management Equity Research relies on a disciplined
systematic approach to both stock selection quantitative portfolio construction.
The research process is focused on identifying investment characteristics and
factors that will work consistently across a broad group of stocks.

Analysis

The Russell 2500 Index (the "Index") gained 15.17% during the fiscal year ending
September 30, 2007. In a reversal of the long-running trend, growth components
of the Index far outperformed value over the period. Industrials were the
biggest contributor to the performance of the Index over the past year, as
capital goods securities continued to rise. Energy rallied on the back of strong
oil prices and heightened supply concerns, and materials posted excellent
returns on climbing commodity prices amid growing global demand. Beginning in
early 2007, financials stocks experienced a substantial drop in performance:
banks suffered as investors became concerned over credit risk on subprime
residential loans, and REITs gave back most of their fourth quarter 2006 gains
as the housing market slowed. Consumer discretionary stocks, especially those in
retailing, lagged the Index for the period as investors worried about consumer
spending in the face of tighter credit conditions and rising gas prices.

The Tax-Managed Small Cap Fund, Class A, gained 16.00% over the past 12 months.
The benefit from the Fund's underweight to financials was mitigated by difficult
stock selection in that area, but stock selection in the consumer discretionary
sector elevated Fund performance above the broad market. On a manager level,
David J. Greene and Company's superior stock selection in industrials and energy
contributed to its outperformance, while Delaware Management Company performed
the same feat with regard to consumer discretionary. McKinley Capital
Management's exposure to high price momentum stocks lifted its returns above the
benchmark. Quantitative manager LSV Asset Management lagged the benchmark for
the fiscal year after struggling in the summer of 2007 as many valuation metrics
exhibited negative returns. Mazama Capital Management was hurt by an underweight
to materials and individual holdings in information technology.

During the fiscal year, SIMC added Los Angeles Capital Management Equity
Research as a sub-adviser to the portfolio.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FUND PERFORMANCE
SEI INSTITUTIONAL MANAGED TRUST -- SEPTEMBER 30, 2007

Small/Mid Cap Diversified Alpha Fund

Objective

The Small/Mid Cap Diversified Alpha Fund (the "Fund") seeks to provide long-term
growth of capital and income by investing in the equity securities of small and
mid-cap companies and in portfolio strategies designed to correlate to a
portfolio composed of small- and mid-cap equity securities. While the Fund is
expected to have an absolute return and risk profile similar to the broad U.S.
small/mid cap equity market, returns may be derived in part from investing
significant portions of the Fund in securities outside of the small/mid cap
market.

Strategy

The Fund uses a multi-manager approach under the general supervision of SEI
Investments Management Corporation ("SIMC"), allocating the assets among
multiple sub-advisers that use different investment strategies to seek to
achieve returns in excess of the performance of a broad U.S. large cap
benchmark. This allocation among investment strategies aims to diversify the
sources from which sub-advisers seek to achieve excess returns (i.e., returns in
excess of a benchmark index), and thereby diversify the relative risk of the
Fund.

Some sub-advisers may engage in short sales up to 30% of the value of their Fund
allocation and use the proceeds from the sale to purchase long positions in
additional equity securities. Some sub-advisers may also use portfolio
strategies that are designed to correlate with a portfolio of small/mid cap
equity securities, but which are composed of derivative instruments backed by
other types of securities.

Los Angeles Capital Management and Equity Research, Martingale Asset Management,
and PanAgora Asset Management seek to overweight stocks with attractive
fundamental and/or technical characteristics and underweight with unattractive
fundamental and/or technical characteristics. All three sub-advisers use
quantitative techniques to identify stock characteristics or factors that they
believe are predictive of future outperformance, although the specific factors,
definition of the factors and the factor weights in the model vary from
sub-adviser to sub-adviser. Integrity Asset Management uses a blend of
qualitative and quantitative elements at each step of their process and focuses
on the timing of purchases to avoid value traps.

Wellington Management Company focuses on companies that demonstrate growth at
reasonable prices. Smith Breeden Associates seeks to generate alpha within the
U.S. fixed income market and transports it to the equity market.

Analysis

The Small/Mid Cap Diversified Alpha Fund, Class A, gained 1.71% for period
December 20, 2006 through September 30, 2007, which represents the inception
date of the Fund through the fiscal year-end.

In a reversal of the long-running trend, growth components of the Russell 2500
Index (the "Index") far outperformed value over the period. Industrials were the
biggest contributor to the performance of the Index over the past year, as
capital goods securities continued to rise. Energy rallied on the back of strong
oil prices and heightened supply concerns, and materials posted excellent
returns on climbing commodity prices amid growing global demand. Beginning in
early 2007, financials stocks experienced a substantial drop in performance:
banks suffered as investors became concerned over credit risk on subprime
residential loans, and REITs gave back most of their fourth quarter 2006 gains
as the housing market slowed. Consumer discretionary stocks, especially those in
retailing, lagged the Index for the period as investors worried about consumer
spending in the face of tighter credit conditions and rising gas prices.

The Fund trailed the overall small/mid cap equity market for the period.
PanAgora Asset Management and Martingale Asset Management struggled,
particularly in August, as quantitative strategies due to forced liquidations
from other levered quantitative funds. Stocks with value-oriented
characteristics significantly underperformed in August, which hurt both
sub-advisers. These sub-advisers also have the ability to short-sell up to 30%
of their portfolios and re-invest the proceeds into additional long securities.
This added flexibility modestly detracted from results. Although Los Angeles
Capital Management and Equity Research also gave up some ground over the summer,
it ended the fiscal period ahead due to its strong outperformance early in the
year. Los Angeles Capital Management and Equity Research had less of an exposure
to value-oriented factors, so they were able to hold onto most of their gains
during the sharp growth/value reversal that occurred in the third quarter.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FUND PERFORMANCE
SEI INSTITUTIONAL MANAGED TRUST -- SEPTEMBER 30, 2007

Wellington Management Company benefited from its growth orientation as well as
its overweight to the materials sector which enjoyed strong gains. Integrity
outperformed value-oriented stocks, although was roughly in-line with the
overall small/mid market as value-oriented stocks trailed for the period. Smith
Breeden Associates underperformed for the period as the subprime crisis impacted
their A-rated and above mortgage-backed security holdings. In addition,
corporate and asset-backed securities experienced negative returns as compared
to comparable treasury securities, which also negatively impacted Smith Breeden
Associates. The derivative strategy used to gain small/mid cap equity exposure
modestly outperformed the actual Index due to favorable derivative supply/demand
characteristics and pricing for the period.

There were no sub-adviser changes during the fiscal year.

Mid-Cap Fund

Objective

The Mid-Cap Fund (the "Fund") seeks to provide long-term capital appreciation by
investing primarily in equity securities of mid-sized companies in a core style.

Strategy

Martingale Asset Management employs a systematic approach focused on valuation,
relative performance and management quality. They select stocks of companies
that have low price-earnings ratios and price-book ratios, but that also have
high sustainable growth levels and the probability of high positive earnings
revisions. Quantitative Management Associates believes that markets are largely
efficient, but investors make occasional, systematic mistakes and that
quantitative investment processes that reduce the influence of biases on
investment decisions more effectively identify and exploit these mistakes.
Quantitative Management Associates emphasizes different measures depending on
the growth rate of a company to identify and exploit mispriced stocks.

Analysis

The Russell Mid-Cap Index (the "Index") continued its upward track, gaining
17.87% for the fiscal year ending September 30, 2007. Industrials were the
biggest contributor to the performance of the Index over the past year, as
capital goods securities continued to rise. Energy rallied on the back of strong
oil prices and heightened supply concerns, and materials posted excellent
returns on climbing commodity prices amid growing global demand. Beginning in
early 2007, financials stocks experienced a substantial drop in performance:
banks suffered as investors became concerned over credit risk on sub-prime
residential loans, and REITs gave back most of their fourth quarter 2006 gains
as the housing market slowed. Consumer discretionary stocks, especially those in
consumer durables and apparel, lagged the Index for the period as investors
worried about consumer spending in the face of tighter credit conditions and
rising gas prices.

The Mid-Cap Fund, Class A, posted a return of 17.51% over the prior 12 months.
The Fund benefited from an overweight to the surging materials area and an
underweight to the lagging consumer discretionary sector, although difficult
stock selection in the latter mitigated much of the gain. Positive stock
selection in industrials and health care boosted returns, while individual
securities in utilities detracted. Martingale Asset Management's exposure to
price momentum was beneficial, although their bets on companies with high cash
flow yield hurt them during the period. Going forward, the portfolio will
continue to be broadly diversified across all sectors and will provide exposure
to mid cap stocks in the domestic equity stock market.

During the fiscal year, SEI Investments Management Corporation added
Quantitative Management Associates as a sub-advisor to the portfolio.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FUND PERFORMANCE
SEI INSTITUTIONAL MANAGED TRUST -- SEPTEMBER 30, 2007

U.S. Managed Volatility Fund

Objective

The U.S. Managed Volatility Fund (the "Fund") invests in common stocks and other
equity securities and employs a broad range of investment strategies intended to
generate capital appreciation, but with a lower level of volatility than the
broad U.S. equity markets.

Strategy

The Fund uses a multi-manager approach, relying on a number of sub-advisers with
differing investment approaches to manage portions of the Fund's portfolio under
the general supervision of SEI Investments Management Corporation ("SIMC"). Each
sub-adviser, in managing its portion of the Fund's assets, employs various
investment strategies intended to achieve returns similar to that of the broad
U.S. equity markets, but with a lower level of volatility over the long-term.
The Fund seeks to achieve lower volatility by constructing a portfolio of
securities that effectively weights securities based on their total expected
risk and return, without regard to market capitalization, industry or tracking
error targets relative to the broad market. As such, the Fund is expected to
have meaningful differentiations in terms of sector weights and short-term
performance relative to broad market indices.

The Fund utilizes Aronson + Johnson + Ortiz and Analytic Investors as
sub-advisers, each brings a differentiated investment and risk model.

Analysis

The U.S. Managed Volatility Fund, Class A, returned 16.09% for the fiscal year
ended September 30, 2007. The S&P 500 Index returned 16.44% for the fiscal year
ended September 30, 2007.

U.S. stocks rallied strongly during the fiscal year returning close to 17% for
the one year ending September 30, 2007 as measured by the Russell 3000 Index.
Investors were encouraged by strong global economic growth and seemed to adjust
well to slowing growth in the U.S. following record double digit growth for
multiple prior quarters. The rally came in spite of rising oil prices to above
$80 a barrel as well as weakness in housing and ongoing sub-prime fears. The
fiscal year started out on a strong note as large cap stocks rallied for the
first several months on strong global economic news, low unemployment and a
continued torrid pace of merger and acquisition and private equity activity.
Investors pushed through a temporary setback in late February when the market
fell by 3.5% in a single day. Subprime fears came to a head in late July and
early August, when credit markets seized up and spilled over into equity markets
sending the broader market down close to 10% from the mid-July peaks to
mid-August. This market weakness tended to hit quantitative managers the hardest
due to what we believe to be a shift in capital market flows and hedge fund
trading. Once again, however, markets regained their footing as global central
banks injected liquidity into financial markets, and investors began to price in
a 25 basis points or 50 basis points rate cut by the U.S. Federal Reserve. By
the end of September, markets were once again approaching new highs.

The energy and materials sectors, within the U.S. market, continued to lead
markets as both returned approximately 40% for the fiscal year. Energy rallied
on the back of strong oil prices and heightened supply concerns. The financials
sector was the significant underperformer; weighed down by subprime fallout.
Thrifts and mortgage finance, consumer finance, as well as the large money
center banks were among the weakest performers. The fiscal year witnessed the
reversal of two significant and long-running trends in the U.S. equity market:
the under-performance of growth and the underperformance of megacaps. The
Russell 1000 Growth Index outpaced the Russell 1000 Value Index by close to 5%
as both stronger growing and more expensive stocks, as measured by P/E,
outperformed. Although the largest 10% and 20% of the stock universe performed
slightly below the broad market for the entire fiscal year, these stocks staged
a sharp comeback starting in the third fiscal quarter.

Given the Fund is not managed against a specific benchmark, we would expect it
to vary significantly from the broad market performance on a shorter-term basis.
In particular, the Fund generally favors stocks with relatively low beta to the
overall equity market, such as utilities and consumer staples, and largely
avoids stocks with high beta, such as information technology. We would expect
the Fund to have a difficult time keeping up with strongly rallying markets.
Given the close to 17% return for the broad market during this period, we are
pleased with the portfolio performance. For the fiscal period, being underweight
the rallying energy and information technology sectors had a negative impact on
portfolio relative performance. However, this was largely offset by the positive
impact of an underweight financials and consumer discretionary.

There were no sub-adviser changes during the fiscal year.

The Fund utilizes Acadian Asset Management and Analytic Investors as
sub-advisers, each brings a differentiated investment and risk model.

Analysis

The Global Managed Volatility Fund, Class A, returned 9.88% for the fiscal year
period ending September 30, 2007. The Morgan Stanley MSCI World Index returned
21.10% for the fiscal year ended September 30, 2007.

Global stocks rallied strongly during the fiscal year returning 18% in U.S.
dollar hedged terms as measured by the Morgan Stanley World Index hedged into
U.S. dollars for the one year ending September 30, 2007. Investors were
encouraged by strong global economic growth and seemed to adjust well to slowing
growth in the U.S. following record double digit growth for multiple prior
quarters. The rally came in spite of rising oil prices to above $80 a barrel as
well as weakness in housing and ongoing sub-prime fears. The fiscal year started

came to a head in late July and early August, when credit markets seized up and
spillover into equity markets sent the broad market down sharply from the
mid-July peaks to mid-August. This market weakness tended to hit quantitative
managers the hardest due to what we believe to be a shift in capital market
flows and hedge fund trading. Once again however, markets regained their footing
as global central banks injected liquidity into financial markets. The energy
and materials sectors, within the global market, continued to lead markets as
these sectors returned 36 and 53% respectively. The financials sector was the
significant underperformer weighed down by the consumer finance and mortgage
finance companies.

Given the Fund is not managed against a specific benchmark, we would expect it
to vary significantly from the broad market performance on a shorter-term basis.
In particular, the Fund generally favors stocks with relatively low beta to the
overall equity market, such as utilities, health care, and consumer staples, and
largely avoids stocks with high beta, such as information technology. For the
fiscal period, the portfolio suffered from negative sector allocation. In
particular, the portfolio was significantly underweight the more cyclical areas
of the market including the materials, energy and industrials sectors that
rallied sharply during the fiscal year. The positive impact of being underweight
the lagging financials sectors helped to mitigate relative losses.

There were no sub-adviser changes during the fiscal year.

Real Estate Fund

Objective

The Real Estate Fund (the "Fund") seeks to provide total return including
current income and capital appreciation by investing in real estate securities.

Strategy

With respect to this Fund, SEI Investments Management Corporation ("SIMC")
employs a multi-manager structure to gain exposure to the entire real estate
sector in the U.S. The Fund is non-diversified and expects to hold a small
number of securities, thus increasing the importance of each holding. The Fund
will invest at least 80% of its net assets in equity securities of real estate
investment trusts ("REITs") and real estate operating companies. The Fund is
jointly sub-advised by two investment managers. Assets of the Fund are
strategically allocated among its two sub-advisors, 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. Security Capital Research and Management
integrates research on real estate sub-market analysis with fundamental company
analysis to find attractively priced securities. Wellington Management Company
utilizes a unique risk/reward relative valuation assessment to identify
attractive real estate investments.

Analysis

The Wilshire Real Estate Securities (Full Cap) Index (the "Index") rose 3.87%
for the year ending September 30, 2007. The real estate segment of the market
experienced a broad based slowdown in spring 2007, with all industries posting a
negative return for that period. Two of the largest detractors from the Index's
performance during the fiscal year were the apartment and self storage
industries, while the regional malls industry was a major contributor. Mall
REITs benefited as continuing strong demand for retail space drove rent spreads
higher. Apartment REITs suffered due to an inventory glut, as slowing home sales
increased vacancy rates.

The Real Estate Fund, Class A, returned 5.49% over the past 12 months. The Fund
saw broad based solid performance, besting the benchmark in nine of the twelve
sectors. Wellington Management Company had substantial influence on the Fund,
adding to returns through stock selection in hotels and an underweight to the
lagging apartments industry. The manager's overweight to the outperforming
health care area also boosted performance. Security capital saw flat returns for
the period, as an overweight to health care was mitigated by difficult stock
selection in the office industry.

Enhanced Income Fund

Objective

Using multiple sub-advisers, the Enhanced Income Fund (the "Fund") seeks to
provide an enhanced return above LIBOR (London InterBank Offered Rate).

Strategy

The Fund investment strategy focuses on generating absolute return through the
management of securities in multiple asset classes, including currency
management. The Fund's managers employ security selection to invest in a
diversified portfolio of short duration investment grade and non-investment
grade fixed-income securities, including bank loans. Active currency management
is also utilized to enhance long term performance.

Analysis

Over the last 12 months, the dynamics and performance of the fixed income
markets changed dramatically as the severe housing slowdown went from being a
subprime mortgage issue to a full blown liquidity and credit crunch. Escalating
concerns about the potential negative effects on economic growth and credit
conditions prodded the Federal Reserve to cut the Fed Funds rate by 0.50% in
September and other central banks to likewise provide vast amount of liquidity
to their financial systems. As of September 30, 2007, short term U.S. interest
rates were lower by 70 basis points and the U.S. dollar weakened considerably
versus other major currencies.

Every major fixed income asset class was negatively affected by the tumult, but
especially those associated with residential real estate. Investors went on a
buyers strike and refused to purchase anything even remotely associated with
mortgage loans. The rating agencies added to the negative mix by downgrading or
watch-listing hundreds of deals. The cessation of liquidity spilled to the
corporate market, pushing spreads wider by 50 to 150 basis points. Valuations
plummeted regardless of quality or structure, causing severe mark-to-markets
that forced hedge fund and other levered investors to sell high quality assets
(i.e. AAA rated) to meet margin calls and enhance their liquidity. Financial
institutions cautiously protected their own balance sheets and balked at
providing liquidity to their peers and others. Short term markets effectively
ceased functioning, causing LIBOR rates to skyrocket in early September to 5.73%
before gradually returning to 5.23% by September 30, 2007. The Enhanced Income
Fund, Class A, posted a 2.96% return for the year ended September 30, 2007.

The Fund did not keep pace with LIBOR during the fiscal year. After producing
good results in the first 9 months, the Fund's strategy struggled in Q3 2007
with the severe dislocation in the fixed income markets. The enhanced cash
strategy was penalized due to its allocation to the structured (asset-backed
securities and mortgage-backed securities) and investment grade credit sectors,
while the bank loan strategy lagged due to risk-repricing and illiquidity in the
market due to forced liquidations by bank loan funds. Unsold inventory on
dealers' balance sheets added to the negative technical conditions in the loan
market. However, from a fundamental standpoint, the loan market is in good shape
with defaults at all-time low levels, ending the year at 0.30%. The currency
strategy led the benchmark for the fiscal year; however, some gains were given
up in Q3 as the carry trade unwound with higher yielding currencies
underperforming lower yielding ones. Winning strategies included a long position
in British Pound Sterling, Australian Dollar, and New Zealand Dollar and short
positions in Japanese Yen and the Swiss Franc.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FUND PERFORMANCE
SEI INSTITUTIONAL MANAGED TRUST -- SEPTEMBER 30, 2007

Core Fixed Income Fund

Objective

The Core Fixed Income Fund (the "Fund") seeks to provide current income and
preservation of capital.

Strategy

The 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 sub-advisers primarily concentrate on sector and
issue selection to add value. In addition, the sub-advisers may engage in
currency transactions using futures, foreign currency forward contracts and
other derivatives either to seek to hedge the Fund's currency exposure or to
enhance the Fund's return. This Fund also allows tactical allocation to high
yield and emerging markets debt.

Analysis

The U.S. investment grade bond market returned 5.13% for the fiscal year ended
September 30, 2007, as measured by the Lehman Aggregate Bond Index. The Core
Fixed Income Fund, Class A, posted a 4.00% return for the same period. Over the
last 12 months, two and ten year Treasury yields declined by 0.70% and 0.04%
respectively. Yields fell for the majority of the period as investors expected
the U.S. Federal Reserve to ease monetary policy. This was exacerbated by the
subprime turmoil in 2007 as a flight to quality ensued and liquidity dried up.
The surprise 50 basis points easing of the Fed Funds rate (market expectations
were for 25 basis points) went a long way in restoring confidence and
maneuverability to bond investors. Other central banks helped to calm investors
as well by likewise providing vast amounts of liquidity to their financial
systems. These shifts in interest rates caused the slope of the yield curve (or
the difference between ten year Treasury yields and two year Treasury yields) to
steepen by 0.66%.

The behavior of the spread sectors was worse than U.S. Treasuries and all spread
sectors underperformed equivalently matched Treasuries during the period.
Investors went on a buyers strike and refused to purchase anything even remotely
associated with subprime mortgage loans. In a "liquidity squeeze" high quality
securities are the easiest investments for investors to sell and that's exactly
what drove agency the mortgage-backed securities ("MBS") and commercial
mortgage-backed securities ("CMBS") prices lower. The brunt of underperformance
took place in the third quarter of 2007 as the so called "contagion" spread to
all areas of the market. Corporate bonds suffered as well with liquidity
evaporating and the new issue market shutting down. The asset-backed security
("ABS") sector was hurt the most by the higher volatility and repricing of risk
with the home equity sub-sector contributing to the majority of
underperformance. Throughout most of 2006, spreads for ABS continued to move
tighter despite significant new issuance due to unprecedented demand from non
traditional investors, including hedge funds and collateralized debt
obligations. This reversed in 2007 as the housing market slowed and we saw
increased delinquencies and foreclosures.

The Fund's interest rate positioning contributed to performance for the period
while sector allocations had an adverse impact. The overall underweight to the
corporate sector helped the Fund; however, an allocation to higher beta
corporates at the long end of the curve more than offset the sector call. The
material overweights to the structured sectors, MBS, CMBS and ABS were the prime
reasons for trailing returns versus the benchmark. Security selection,
especially in asset-backed sector of the market, also played a significant role
in the Fund's negative excess performance.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FUND PERFORMANCE
SEI INSTITUTIONAL MANAGED TRUST -- SEPTEMBER 30, 2007

High Yield Bond Fund

Objective

The investment objective of the High Yield Bond Fund (the "Fund") is to maximize
total return by investing primarily in a diversified portfolio of higher
yielding, lower rated fixed income securities. The strategy seeks to achieve a
high level of total return 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 macroeconomic, 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 Merrill Lynch U.S. High Yield Master II Constrained Index posted a 7.79%
return during the 12-month period ending September 30, 2007, as default rates
hovered near all-time lows and corporate fundamentals remained in good shape.
Cable was the top performing sector with companies gathering more subscribers
with their triple-play offering of cable, phone, and internet services. The
additional revenue, lower cost of debt, and improving balance sheets has been a
positive for the sector. The building and construction sector was the worst
performing sector as the housing market weakened during the period primarily due
to subprime mortgage concerns. The subprime phenomenon led to slower home sales
and weaker financial results for homebuilders. The support services sector was a
solid performer led by United Rentals. The company posted good financial results
during the period and also agreed to be acquired by a private equity firm. The
beverage sector was the second worst performing segment for the period. The
sector was dragged down by water and juice producer Le-Natures, whose bonds
plummeted more than 85% after it was discovered that the company was involved in
fraudulent activities. Moody's U.S. issuer-based default rate continued to trend
toward historical lows. The trailing twelve month reading of 1.2% is the lowest
since March 1982 when it was 1.0%. The market is anticipating default rates to
increase slowly over the next twelve months but to remain below the historical
average.

The High Yield Bond Fund, Class A, trailed the index with a 6.72% return for the
fiscal year ended September 30, 2007. The Fund's underweight to Williams
Companies was a negative for the period as the company outperformed the high
yield market due to solid financial results and an asset sale. The Fund's
underweight to Charter Communications was a negative as the firm was the top
contributor to the index return. The company gathered more subscribers with
their triple-play offering of cable, phone, and internet services. The Fund's
overweight to Le-Natures was a negative as corporate fraud hammered bond prices.
The Fund's exposure to structured credit, such as collateralized debt
obligations, was a negative as well. The Fund's exposure to TDS Investor was a
positive as the company agreed to merge with Worldspan, sending bonds higher.
Finally, the Fund's underweight to building and construction was a positive as
the slumping homebuilder sector was a poor performer.

Managed Volatility Funds have not yet commenced operations.

2. SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of the significant accounting policies followed by
the Funds.

USE OF ESTIMATES -- The preparation of financial statements, in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of increases and decreases in net assets
from operations during the reporting period. Actual results could differ from
those estimates.

SECURITY VALUATION -- Securities listed on a securities exchange, market or
automated quotation system for which quotations are readily available (except
for securities traded on NASDAQ) are valued at the last quoted sale price on the
primary exchange or market (foreign or domestic) on which they are traded, or,
if there is no such reported sale, at the most recent quoted bid price. For
securities traded on NASDAQ, the NASDAQ Official Closing Price will be used. If
available, debt securities are priced based upon valuations provided by
independent, third-party pricing agents. Such values generally reflect the last
reported sales price if the security is actively traded. The third-party pricing
agents may also value debt securities at an evaluated bid price by employing
methodologies that utilize actual market transactions, broker-supplied
valuations, or other methodologies designed to identify the market value for
such securities. Debt obligations with remaining maturities of sixty days or
less may be valued at their amortized cost, which approximates market value.
Prices for most securities held in the Funds are provided daily by recognized
independent pricing agents. If a security price cannot be obtained from an
independent, third-party pricing agent, the Funds seek to obtain a bid price
from at least one independent broker.

Securities for which market prices are not "readily available" are valued in
accordance with Fair Value Procedures established by the Funds' Board of
Trustees. The Funds' Fair Value Procedures are implemented through a Fair Value
Committee (the "Committee") designated by the Funds' Board of Trustees. Some of
the more common reasons that may necessitate that a security be valued using
Fair Value Procedures include: the security's trading has been halted or
suspended; the security has been de-listed from a national exchange; the
security's primary trading market is temporarily closed at a time when, under
normal conditions, it would be open; or the security's primary pricing source is
not able or willing to provide a price. When a security is valued in accordance
with the Fair Value Procedures, the Committee will determine the value after
taking into consideration relevant information reasonably available to the
Committee.

For securities that principally trade on a foreign market or exchange, a
significant gap in time can exist between the time of a particular security's
last trade and the time at which a Fund calculates its net asset value. The
closing prices of such securities may no longer reflect their market value at
the time the Fund calculates net asset value if an event that could materially
affect the value of those securities (a "Significant Event") has occurred
between the time of the security's last close and the time that the Fund
calculates net asset value. A Significant Event may relate to a single issuer or
to an entire market sector. If the adviser or sub-adviser of a Fund becomes
aware of a Significant Event that has occurred with respect to a security or
group of securities after the closing of the exchange or market on which the
security or securities principally trade, but before the time at which the Fund
calculates net asset value, it may request that a Fair Value Committee Meeting
be called. In addition, the Funds' administrator monitors price movements among
certain selected indices, securities and/or baskets of securities that may be an
indicator that the closing prices received earlier from foreign exchanges or
markets may not reflect market value at the time the Fund calculates net asset
value. If price movements in a monitored index or security exceed levels
established by the administrator, the administrator notifies the adviser or
sub-adviser for any Fund holding the relevant securities that such limits have
been exceeded. In such event, the adviser or sub-adviser makes the determination
whether a Fair Value Committee Meeting should be called based on the information
provided.

Options and warrants for which the primary market is a national securities
exchange are valued at the last sale price on the exchange on which they are
traded, or, in the absence of any sale, at the closing

bid price. Options and warrants not traded on a national securities exchange are
valued at the last quoted bid price.

SECURITY TRANSACTIONS AND INVESTMENT INCOME -- Security transactions are
recorded on the trade date. Costs used in determining net realized capital gains
and losses on the sale of securities are on the basis of specific
identification. Dividend income is recognized on the ex-dividend date, and
interest income is recognized using the accrual basis of accounting. Income from
payment-in-kind securities is recorded daily based on the effective interest
method of accrual.

Distributions received on securities that represent a return of capital or
capital gain are recorded as a reduction of cost of investments and/or as a
realized gain. The trust estimates the components of distributions received that
may be considered nontaxable distributions or capital gain distributions.

Amortization and accretion is calculated using the scientific interest method,
which approximates the effective interest method over the holding period of the
security. Amortization of premiums and discounts is included in interest income.

REPURCHASE AGREEMENTS -- Securities pledged as collateral for repurchase
agreements are held by each Fund's custodian bank until the repurchase date 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 the
repurchase date of the repurchase agreement. Provisions of the repurchase
agreements and the Trust's policies 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.

REVERSE REPURCHASE AGREEMENTS -- The Core Fixed Income Fund may issue reverse
repurchase agreements. A reverse repurchase agreement involves the sale of
portfolio assets together with an agreement to repurchase the same assets later
at a fixed price. Additional assets are maintained in an account with the
broker. The segregated assets may consist of cash, U.S. Government securities,
or other liquid securities at least equal in value to the obligations under the
reverse repurchase agreements. In the event the buyer of securities under a
reverse repurchase agreement files for bankruptcy or becomes insolvent, the
Fund's use of the proceeds under the agreement may be restricted pending a
determination by the other party, or its trustee or receiver, whether to enforce
the obligation to repurchase the securities. There were no reverse repurchase
agreements outstanding as of September 30, 2007.

COMPENSATING BALANCES -- Funds with cash overdrafts in excess of $100,000 are
required to leave 112% in compensating balance with US Bank, 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 US Bank on the
following day.

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 daily 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 class on the basis of relative daily net assets.

FOREIGN CURRENCY TRANSLATION -- The books and records of the Funds 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 Funds do not isolate that portion of gains and losses on investments in
equity securities that is due to changes in the foreign exchange rates from that
which is due to changes in market prices of equity securities.

The Funds report 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.

FORWARD FOREIGN CURRENCY CONTRACTS -- The Small Cap Growth, Global Managed
Volatility, Enhanced Income and Core Fixed Income Funds may enter into forward
foreign currency contracts as hedges against either specific transactions, fund
positions or anticipated fund positions. The Core Fixed Income Fund may also
engage in currency transactions to enhance the Fund's returns. All commitments
are "marked-to-market" daily at the applicable foreign exchange rate, and any
resulting unrealized gains or losses are recorded currently. The Small Cap
Growth and Core Fixed Income Funds realize gains and losses at the time forward
contracts are extinguished. Unrealized gains or losses on outstanding positions
in forward foreign currency contracts held at the close of the period are
recognized as ordinary income or loss for Federal income tax purposes. The Funds
could be exposed to risk if the counterparties to the contracts are unable to
meet the terms of the contract and from unanticipated movements in the value of
a foreign currency relative to the U.S. dollar. Finally, the risk exists that
losses could exceed amounts disclosed on the Statement of Assets and
Liabilities. At the year ended September 30, 2007, the Small Cap Growth Fund did
not have any forward currency contracts outstanding.

FUTURES CONTRACTS -- All Funds, with the exception of the Real Estate and High
Yield Bond Funds, utilized futures contracts during the year or period ended
September 30, 2007. The Funds' investments in futures contracts are designed to
enable the Funds to more closely approximate the performance of their benchmark
indices. The Core


- --------------------------------------------------------------------------------
220         SEI Institutional Managed Trust / Annual Report / September 30, 2007



Fixed Income Fund may use futures contracts for tactical hedging purposes as
well as to enhance the Fund's returns. 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 gains or losses 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 of entering into futures contracts include the possibility that there will
be an imperfect price correlation between the futures and the underlying
securities. Second, it is possible that a lack of liquidity for futures
contracts could exist in the secondary market, resulting in an inability to
close a position prior to its maturity date. Third, the futures contract
involves the risk that the fund could lose more than the original margin deposit
required to initiate a futures transaction.

Finally, the risk exists that losses could exceed amounts disclosed on the
Statement of Assets and Liabilities.

OPTIONS/SWAPTIONS WRITING/PURCHASING -- Each Fund may invest in financial
options/swaptions contracts 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. The Core Fixed Income Fund may also invest in financial option/swaption
contracts to enhance the Fund's returns. When the Fund writes or purchases an
option/swaption, 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/swaption written or purchased. Premiums received or
paid from writing or purchasing options/swaptions 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/swaption 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. The Large Cap Diversified Alpha, Small/Mid Cap
Diversified Alpha and Core Fixed Income Funds had option/swaption contracts as
of September 30, 2007 as disclosed in the Fund's Schedule of Investments.

The risk in writing a call option/swaption is that the Funds give up the
opportunity for profit if the market price of the security increases. The risk
in writing a put option/swaption is that the Funds may incur a loss if the
market price of the security decreases and the option/swaption is exercised. The
risk in purchasing an option/swaption is that the Funds pay a premium whether or
not the option/swaption is exercised. The Funds also have the additional risk of
being unable to enter into a closing transaction at an acceptable price if a
liquid secondary market does not exist. Option/swaption contracts also involve
the risk that they may not work as intended due to unanticipated developments in
market conditions or other causes.

Finally, the risk exists that losses on written options could exceed amounts
disclosed on the Statement of Assets and Liabilities.

Written option transactions entered into during the year or period ended
September 30, 2007 are summarized as follows:

Notes to Financial Statements (Continued)

September 30, 2007

SWAP AGREEMENTS -- A swap agreement is a two-party contract under which an
agreement is made to exchange returns from predetermined investments or
instruments, including a particular interest rate, foreign currency, or "basket"
of securities representing a particular index. Interest rate swaps involve the
exchange by a Fund with another party of their respective commitments to pay or
receive interest (e.g., an exchange of floating rate payments for fixed rate
payments) with respect to a notional amount of principal. Credit-default swaps
involve periodic payments by the Fund or counterparty based on a specified rate
multiplied by a notional amount assigned to an underlying debt instrument or
group of debt instruments in exchange for the assumption of credit risk on the
same instruments. In the event of a credit event, usually in the form of a
credit rating downgrade, the party receiving periodic payments (i.e. floating
rate payer) must pay the other party (i.e. fixed rate payer) an amount equal to
the outstanding principal of the downgraded debt instrument, and also take
possession of the instrument. Total return swaps allow an investor to benefit
from the cash flow without ever actually owning the underlying security. The
receiver must pay any decline in value to the payer at the end of the total
return swap. However, the investor does not need to make a payment if there is
no decline in price. Payments can be made on various indices, bonds (i.e.
mortgage backed securities, bank debt and corporate), loans or commodities. The
value of a total return swap is equal to the change in value of the underlying
asset versus the accrued income payment based on LIBOR or some other form of
indices on the notional amount. Interest rate swaps involve the exchange by a
Fund with another party of their respective commitments to pay or receive
interest (e.g., an exchange of floating rate payments for fixed rate payments)
with respect to a notional amount of principal to manage the Fund's exposure to
interest rates. Payments received or made are recorded as realized gains or
loss. The Fund could be exposed to credit or market risk due to unfavorable
changes in the fluctuation of interest rates or if the counterparty defaults on
its obligation to perform. Risk of loss may exceed amounts recognized on the
statement of assets and liabilities. Interest rate swap contracts outstanding at
period end, if any, are listed after the Fund's portfolio. In connection with
swap agreements securities may be set aside as collateral by the Fund's
custodian. A Fund may enter into swap agreements in order to, among other
things, change the maturity or duration of the investment portfolio, to protect
the Fund's value from changes in interest rates, or to expose a Fund to a
different security or market.

Swaps are marked-to-market daily based upon quotations from market makers and
the resulting changes in market values, if any, are recorded as an unrealized
gain or loss in the Statement of Operations. Net payments of interest are
recorded as realized gains or losses.

Entering into swap agreements involves, to varying degrees, elements of credit
and market risk in excess of the amounts recognized on the Statement of Assets
and Liabilities. Such risks involve the possibility that there will be no liquid
market for these agreements, that the counterparty to the agreement may default
on its obligation to perform and that there may be unfavorable changes in the
fluctuation of interest rates. Risks also arise from potential losses from
adverse market movements.

DELAYED DELIVERY TRANSACTIONS -- The Core Fixed Income Fund may purchase or sell
securities on a when-issued or delayed delivery basis. These transactions
involve a commitment by the Fund to purchase or sell securities for a
predetermined price or yield, with payment and delivery taking place beyond the
customary settlement period. When delayed delivery purchases are outstanding,
the Fund will set aside liquid assets in an amount sufficient to meet the
purchase price. When purchasing a security on a delayed delivery basis, the Fund
assumes the rights and risks of ownership of the security, including the risk of
price and yield fluctuations, and takes such fluctuations into account when
determining its net asset value. The Fund may dispose of or renegotiate a
delayed delivery transaction after it is entered into, and may sell when-issued
securities before they are delivered, which may result in a capital gain or
loss. When the Fund has sold a security on a delayed delivery basis, the Fund
does not participate in future gains and losses with respect to the security.

COLLATERALIZED DEBT OBLIGATIONS -- The Funds may invest in collateralized debt
obligations ("CDOs"), which include collateralized loan obligations ("CLOs") and
other similarly structured securities. CLOs are a type of asset-backed
securities. A CLO is a trust typically collateralized by a pool of loans, which
may include, among others, domestic and foreign senior secured loans, senior
unsecured loans, and subordinate corporate loans, including loans that may be
rated below investment grade or equivalent unrated loans. CDOs may charge
management fees and administrative expenses.

For CDOs, the cashflows from the trust are split into two or more portions,
called tranches, varying in risk and yield. The riskiest portion is the "equity"
tranche which bears the bulk of defaults from the bonds or loans in the trust
and serves to protect the other, more senior tranches from default in all but
the most severe circumstances. Since it is partially protected from defaults, a
senior tranche from a CDO trust typically has a higher rating and lower yield
than their underlying securities, and can be rated investment grade. Despite the
protection from the equity tranche, CDO tranches can experience substantial
losses due to actual defaults, increased sensitivity to defaults due to
collateral default and disappearance of protecting tranches, market anticipation
of defaults, as well as aversion to CDO securities as a class.

The risks of an investment in a CDO depend largely on the type of the collateral
securities and the class of the CDO in which a Fund invests. Normally, CLOs and
other CDOs are privately offered and sold, and thus, are not registered under
the securities laws. As a result, investments in CDOs may be characterized by
the Funds as illiquid securities; however, an active dealer market may exist for
CDOs, allowing a CDO to qualify for Rule 144A transactions. In addition to the
normal risks associated with fixed income securities (e.g., interest rate risk
and default risk), CDOs carry additional risks including, but are not


- --------------------------------------------------------------------------------
222         SEI Institutional Managed Trust / Annual Report / September 30, 2007



limited to: (i) the possibility that distributions from collateral securities
will not be adequate to make interest or other payments; (ii) the quality of the
collateral may decline in value or default; (iii) the Funds may invest in CDOs
that are subordinate to other classes; and (iv) the complex structure of the
security may not be fully understood at the time of investment and may produce
disputes with the issuer or unexpected investment results.

ILLIQUID SECURITIES -- A security is considered illiquid if it cannot be sold or
disposed of in the ordinary course of business within seven days or less for its
approximate carrying value on the books of the Funds. Valuations of illiquid
securities may differ significantly from the values that would have been used
had an active market value for these securities existed.

RESTRICTED SECURITIES -- At September 30, 2007, the following Funds owned
private placement investments that were purchased through private offerings or
acquired through initial public offerings and cannot be sold without prior
registration under the Securities Act of 1933 or pursuant to an exemption
therefrom. In addition, the Funds have generally agreed to further restrictions
on the disposition of certain holdings as set forth in various agreements
entered into in connection with the purchase of these investments. These
investments are valued at fair value as determined in accordance with the
procedures approved by the Board of Trustees. The acquisition dates of these
investments, the enforceable right to acquire these securities, along with their
cost and values at September 30, 2007, were as follows:

Notes to Financial Statements (Continued)

September 30, 2007

DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- Dividends from net investment
income are declared and paid to shareholders quarterly for the Large Cap Value,
Large Cap Growth, Tax-Managed Large Cap, Large Cap Diversified Alpha, S&P 500
Index, Small Cap Value, Small Cap Growth, Tax-Managed Small Cap, Small/Mid Cap
Diversified Alpha, Mid-Cap, U.S. Managed Volatility, Enhanced Income and Real
Estate Funds; are declared and paid annually for the Global Managed Volatility
Fund; and declared daily and paid monthly for the Core Fixed Income and High
Yield Bond Funds. Any net realized capital gains on sales of securities are
distributed to shareholders at least annually. Dividends and distributions are
recorded on the ex-dividend date.

The Large Cap Value, Large Cap Diversified Alpha, Small Cap Value, Tax-Managed
Small Cap, Mid-Cap and U.S. Managed Volatility Funds utilized earnings and
profits distributed to shareholders on redemption of shares as a part of the
dividends paid deduction for income tax purposes.

INVESTMENTS IN REITS -- With respect to the Real Estate Fund, dividend income is
recorded based on the income included in distributions received from the REIT
investments using published REIT reclassifications including some management
estimates when actual amounts are not available. Distributions received in
excess of this estimated amount are recorded as a reduction of the cost of
investments or reclassified to capital gains. The actual amounts of income,
return of capital, and capital gains are only determined by each REIT after its
fiscal year-end, and may differ from the estimated amounts.

3. AGREEMENTS AND OTHER TRANSACTIONS WITH AFFILIATES

ADMINISTRATION AND TRANSFER AGENCY AGREEMENT -- The Trust and SEI Investments
Global Funds Services (the "Administrator") are parties to an amended and
restated Administration and Transfer Agency Agreement dated December 10, 2003
under which the Administrator provides administrative and transfer agency
services to the Funds for an annual fee of 0.35% of the average daily net assets
of the Large Cap Value, Large Cap Growth, Tax-Managed Large Cap Class A, Large
Cap Diversified Alpha, Small Cap Value, Small Cap Growth, Tax-Managed Small Cap,
Small/Mid Cap Diversified Alpha, Mid-Cap, U.S. Managed Volatility, Global
Managed Volatility, Real Estate, Enhanced Income and High Yield Bond Funds;
0.15% of average daily net assets of the Tax-Managed Large Cap Class Y, 0.22% of
the average daily net assets of the S&P 500 Index Fund; and 0.28% of the average
daily net assets of the Core Fixed Income Fund. The Administrator has agreed to
waive all or a portion of its fee in order to limit the operating expenses of a
Fund. Any such waiver is voluntary and may be terminated at any time at the
Administrator's sole discretion.

INVESTMENT ADVISORY AGREEMENT -- SEI Investments Management Corporation ("SIMC")
serves as investment adviser (the "Adviser") to each Fund. In connection with
serving as Adviser, SIMC is entitled to a fee, which is calculated daily and
paid monthly, based on the average daily net assets of each Fund. SIMC has
voluntarily agreed to waive a portion of its fee so that the total annual
expenses of each Fund, exclusive of short sale expenses, will not exceed certain
voluntary expense limitations adopted by SIMC. These waivers may be terminated
at any time. Accordingly, the advisory fee and voluntary expense limitations for
each Fund are as follows:

Notes to Financial Statements (Continued)

September 30, 2007

PAYMENT BY AFFILIATE -- During the fiscal year ended September 30, 2006, the
Core Fixed Income Fund was reimbursed by a sub-adviser, which was included in
net investment income in the Statement of Changes, for sub-advisory fees
received of $239,132. After terminating its sub-advisory agreement with the
Fund, the sub-adviser agreed to reimburse the Fund for sub-advisory fees
received since their hiring in September 2005. During the fiscal year ended
September 30, 2006, the High Yield Bond Fund was reimbursed by the sub-adviser,
deemed as a "Payment by Affiliate" in the Statement of Changes, for losses
incurred of $2,947 due to the sale of shares in a specific company in excess of
the amount permitted under applicable Securities and Exchange Commission rules.
The reimbursement has no impact on the Fund's total return.

DISTRIBUTION AGREEMENT -- SEI Investments Distribution Co. (the "Distributor"),
a wholly owned subsidiary of SEI Investments Company ("SEI"), serves as each
Fund's Distributor pursuant to a distribution agreement with the Trust. The
Trust has adopted a shareholder servicing plan for Class A, Class E, Class I and
Class Y shares (the "Shareholder Servicing Plans") under which a shareholder
servicing fee of up to 0.25% of average daily net assets attributable to Class A
shares of the Large Cap Value, Large Cap Growth, Tax-Managed Large Cap, Large
Cap Diversified Alpha, Small Cap Value, Small Cap Growth, Tax-Managed Small Cap,
Small/Mid Cap Diversified Alpha, Mid-Cap, U.S. Managed Volatility, Global
Managed Volatility, Real Estate, Enhanced Income, Core Fixed Income and High
Yield Bond Funds, Class E and Class I shares, and a shareholder servicing fee of
up to 0.15% of average daily net assets attributable to Class A shares of the
S&P 500 Index Fund and Class Y shares, will be paid to the Distributor. In
addition to the Shareholder Servicing Plans, the Class I shares have adopted
administrative service plans that provide for administrative service fees
payable to the Distributor of up to 0.25% of the average daily net assets
attributed to that class.

OTHER -- 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. SEC rules
require that such commissions not exceed usual and customary commissions.

6. FEDERAL TAX INFORMATION

It is each Fund's intention to continue to qualify as a regulated investment
company under Subchapter M of The Internal Revenue Code and distribute all of
its taxable income (including net capital gains). Accordingly, no provision for
Federal income taxes is required.

Dividends from net investment income and distributions from net realized capital
gains are determined in accordance with U.S. Federal income tax regulations,
which may differ from those amounts determined under accounting principles
generally accepted in the United States. 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, undistributed net investment
income or accumulated net realized gain, as appropriate, in the period that the
differences arise. Accordingly, the following permanent differences, primarily
attributable to different treatment for gains and losses on paydowns of
mortgage- and asset-backed securities for tax purposes, return of capital, swap
income reclassification, nontaxable redemption in-kind gain/loss, distribution
reclassification, REIT income reclassification and utilization of earnings and
profits on shareholder redemptions and net operating losses have been
reclassified to/from the following accounts as of September 30, 2007:

230         SEI Institutional Managed Trust / Annual Report / September 30, 2007



During the year ended September 30, 2007, the Large Cap Growth, Tax-Managed
Large Cap and Small Cap Growth Funds utilized $202,062,461, $136,812,157 and
$36,498,015, respectively, of capital loss carryforward to offset capital gains.

For Federal income tax purposes, the cost of securities owned at September 30,
2007, and the net realized gains or losses on securities sold for the period,
were different from amounts reported for financial reporting purposes, primarily
due to wash sales which cannot be used for Federal income tax purposes in the
current year and have been deferred for use in future years. The Federal tax
cost and aggregate gross unrealized appreciation and depreciation on investments
held by the Funds at September 30, 2007, were as follows:

7. SECURITIES LENDING

Each Fund may lend portfolio securities to brokers, dealers and other financial
organizations that meet capital and other credit requirements or other criteria
established by the Trust's Board of Trustees. These loans may not exceed
33 1 /3% of the total asset value of the Fund (including the loan collateral).
No Fund will lend portfolio securities to its Adviser, sub-adviser or their
affiliates unless it has applied for and received specific authority to do so
from the SEC. Loans of portfolio securities will be fully collateralized by
cash. Collateral will be maintained in an amount equal to at least 100% of the
current market value of the loaned securities by marking to market daily,
although the borrower will be required to deliver collateral of 102% and 105% of
the market value of borrowed securities for domestic and foreign securities,
respectively. However, due to market fluctuations during the day, the value of
securities loaned on a particular day may, during the course of the day, exceed
the value of collateral. On each business day, the amount of collateral is
adjusted based on the prior day's market fluc-tuations and the current day's
lending activity. Income from lending activity is determined by the amount of
interest earned on collateral, less any amounts payable to the borrowers of the
securities and the lending agent. Lending securities involves certain risks,
including the risk that the Fund may be delayed or prevented from recovering the
collateral if the borrower fails to return the securities.

Cash collateral received in connection with securities lending is invested in
short-term investments by the lending agent. These investments may include
repurchase agreements, which are collateralized by United States Treasury and
Government Agency securities, and high-quality, short-term instruments, such as
floating rate corporate obligations, commercial paper, and private placements
with an average weighted maturity not to exceed 60 days and a maturity not to
exceed 397 days.

8. CONCENTRATIONS/RISKS

In the normal course of business, the Funds enter into contracts that provide
general indemnifications by the Funds to the counterparty to the contract. The
Funds' maximum exposure under these arrangements is dependent on future claims
that may be made against the Funds and, therefore, cannot be estimated; however,
based on experience, the risk of loss from such claims is considered remote.

The market values of the Core Fixed Income and High Yield Bond Funds'
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.

10. NEW ACCOUNTING PRONOUNCEMENTS

On July 13, 2006, the Financial Accounting Standards Board ("FASB") released
FASB Interpretation No. 48 ("FIN 48"), "Accounting for Uncertainty in Income
Taxes". This standard defines the threshold for recognizing the benefits of
tax-return positions in the financial statements as "more-likely-than-not" to be
sustained by the taxing authority and requires measurement of a tax position
meeting the more-likely-than-not criterion, based on the largest benefit that is
more than 50 percent likely to be realized. FIN 48 is effective as of the
beginning of the first fiscal year beginning after December 15, 2006. At
adoption, companies must adjust their financial statements to reflect only those
tax positions that are more-likely-than-not to be sustained as of the adoption
date. Adoption of FIN 48 is required for fiscal years beginning after December
15, 2006 and is to be applied to all open tax years as of the effective date.
Recent SEC guidance allows implementing FIN 48 in fund asset calculations as
late as the fund's last net asset value calculation in the first required
financial statement reporting period. As a result, the Funds, with the exception
of the S&P 500 Index and Small/Mid Cap Diversified Alpha Funds, will incorporate
FIN 48 in their semi-annual report of March 31, 2008. As of September 30, 2007,
management does not anticipate a material impact to the financial statements.
The S&P 500 Index and Small/Mid Cap Diversified Alpha Funds adopted FIN 48 and
management has determined that the adoption of FIN 48 did not have a material
impact to the Fund's financial statements. However, management's conclusions
regarding FIN 48 could change in the future to the extent there are changes in
tax laws and/or additional guidance from the IRS regarding interpretations of
existing laws.

In September 2006, the FASB issued Statement on Financial Accounting Standards
("SFAS") No. 157, "Fair Value Measurements". This standard establishes a single
authoritative definition of fair value, sets out a framework for measuring fair
value and requires additional disclosures about fair value measurements. SFAS
No. 157 applies to fair value measurements already required or permitted by
existing standards. SFAS No. 157 is effective for financial statements issued
for fiscal years beginning after November 15, 2007 and interim periods within
those fiscal years. The changes to current generally accepted accounting
principles from the application of this Statement relate to the definition of
fair value, the methods used to measure fair value, and the expanded disclosures
about fair value measurements. As of September 30, 2007, the Funds do not
believe the adoption of SFAS No. 157 will impact the amounts reported in the
financial statements, however, additional disclosures may be required about the
inputs used to develop the measurements and the effect of certain of the
measurements reported in the financial statements for a fiscal period.

11. OTHER MATTERS

Due to volatility in the fixed income and equity markets, the market value of
some of the Fund's holdings may currently be lower than shown in the Schedules
of Investments ("SOI"). The values shown in the SOI's were the market values as
of September 30, 2007 and do not reflect any market events after September 30,
2007.

232         SEI Institutional Managed Trust / Annual Report / September 30, 2007



Report of Independent Registered Public Accounting Firm

To the Board of Trustees and Shareholders of
SEI Institutional Managed Trust

We have audited the accompanying statements of assets and liabilities, including
the schedules of investments of SEI Institutional Managed Trust, comprising the
Large Cap Value Fund, Large Cap Growth Fund, Tax-Managed Large Cap Fund, Large
Cap Diversified Alpha Fund, S&P 500 Index Fund, Small Cap Value Fund, Small Cap
Growth Fund, Tax-Managed Small Cap Fund, Small/Mid Cap Diversified Alpha Fund,
Mid-Cap Fund, U.S. Managed Volatility Fund, Global Managed Volatility Fund, Real
Estate Fund, Enhanced Income Fund, Core Fixed Income Fund and High Yield Bond
Fund (collectively, the "Funds"), as of September 30, 2007, and the related
statements of operations for the year or period then ended, the changes in net
assets and the financial highlights for each of the years or periods in the
two-year period then ended, and the statements of operations, the changes in net
assets and financial highlights for the year ended March 31, 2006 for the S&P
500 Index Fund. These financial statements and financial highlights are the
responsibility of the Funds' management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits. The financial highlights of the Tax-Managed Large Cap Fund, Large Cap
Value Fund, Large Cap Growth Fund, Tax-Managed Small Cap Fund, Small Cap Value
Fund, Small Cap Growth Fund, Mid-Cap Fund, U.S. Managed Volatility Fund, Real
Estate Fund, Core Fixed Income Fund and High Yield Bond Fund for the years or
periods ended September 30, 2005 and prior, were audited by other auditors. The
financial highlights of the S&P 500 Index Fund for the periods presented through
March 31, 2005 were audited by other auditors. Those auditors expressed an
unqualified opinion on those financial highlights in their reports dated
November 28, 2005 and May 31, 2005, respectively.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of September 30, 2007, by correspondence with custodians and
brokers. As to securities purchased or sold but not yet received or delivered,
we performed other appropriate auditing procedures. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of each
of the funds comprising SEI Institutional Managed Trust as of September 30,
2007, the results of their operations, the changes in their net assets, and the
financial highlights for each of the periods indicated in the first paragraph
above, in conformity with U.S. generally accepted accounting principles.

Disclosure of Fund Expenses (Unaudited)

All mutual funds have operating expenses. As a shareholder of a mutual fund,
your investment is affected by these ongoing costs, which include (among others)
costs for portfolio management, administrative services, and shareholder reports
like this one. It is important for you to understand the impact of these costs
on your investment returns.

Operating expenses such as these are deducted from the mutual fund's gross
income and directly reduce your final investment return. These expenses are
expressed as a percentage of the mutual fund's average net assets; this
percentage is known as the mutual fund's expense ratio.

The following examples use the expense ratio and are intended to help you
understand the ongoing costs (in dollars) of investing in your Fund and to
compare these costs with those of other mutual funds. The examples are based on
an investment of $1,000 made at the beginning of the period shown and held for
the entire period.

The table on the next page illustrates your Fund's costs in two ways:

o ACTUAL FUND RETURN. This section helps you to estimate the actual expenses
after fee waivers that your Fund incurred over the period. The "Expenses Paid
During Period" column shows the actual dollar expense cost incurred by a $1,000
investment in the Fund, and the "Ending Account Value" number is derived from
deducting that expense cost from the Fund's gross investment return.

You can use this information, together with the actual amount you invested in
your Fund, to estimate the expenses you paid over that period. Simply divide
your actual starting account value by $1,000 to arrive at a ratio (for example,
an $8,600 account value divided by $1,000 = 8.6), then multiply that ratio by
the number shown for your Fund under "Expenses Paid During Period."

o HYPOTHETICAL 5% RETURN. This section helps you compare your Fund's costs with
those of other mutual funds. It assumes that your Fund had an annual 5% return
before expenses during the year, but that the expense ratio (Column 3) is
unchanged. This example is useful in making comparisons because the Securities
and Exchange Commission requires all mutual funds to make this 5% calculation.
You can assess your Fund's comparative cost by comparing the hypothetical result
for your Fund in the "Expense Paid During Period" column with those that appear
in the same charts in the shareholder reports for other mutual funds.

NOTE: Because the return is set at 5% for comparison purposes -- NOT your Fund's
actual return -- the account values shown do not apply to your specific
investment.

238         SEI Institutional Managed Trust / Annual Report / September 30, 2007



Board of Trustees Considerations in Approving the Advisory and Sub-Advisory
Agreements (Unaudited)

The SEI Institutional Managed Trust (the "Trust") and SEI Investments Management
Corporation ("SIMC") have entered into an investment advisory agreement (the
"Advisory Agreement"). Pursuant to the Advisory Agreement, SIMC oversees the
investment advisory services provided to the series of the Trust (the "Funds")
and may manage the cash portion of the Funds' assets. Pursuant to separate
sub-advisory agreements (the "Sub-Advisory Agreements" and, together with the
Advisory Agreement, the "Investment Advisory Agreements") with SIMC, and under
the supervision of SIMC and the Trust's Board of Trustees (the "Board"), the
Sub-Advisers are responsible for the day-to-day investment management of all or
a discrete portion of the assets of the Funds. The Sub-Advisers also are
responsible for managing their employees who provide services to these Funds.
The Sub-Advisers are selected based primarily upon the research and
recommendations of SIMC, which evaluates quantitatively and qualitatively the
Sub-Advisers' skills and investment results in managing assets for specific
asset classes, investment styles and strategies.

The Investment Company Act of 1940, as amended (the "1940 Act") requires that
the initial approval of, as well as the continuation of, the Funds' Investment
Advisory Agreements must be specifically approved: (i) by the vote of the Board
of Trustees or by a vote of the shareholders of the Funds; and (ii) by the vote
of a majority of the Trustees who are not parties to the Investment Advisory
Agreements or "interested persons" of any party (the "Independent Trustees"),
cast in person at a meeting called for the purpose of voting on such approval.
In connection with their consideration of such approvals, the Funds' Trustees
must request and evaluate, and SIMC and the Sub-Advisers are required to
furnish, such information as may be reasonably necessary to evaluate the terms
of the Investment Advisory Agreements. In addition, the Securities and Exchange
Commission ("SEC") takes the position that, as part of their fiduciary duties
with respect to a mutual fund's fees, mutual fund boards are required to
evaluate the material factors applicable to a decision to approve an Investment
Advisory Agreement.

Consistent with these responsibilities, the Trust's Board of Trustees calls and
holds meetings each year that are dedicated to considering whether to renew the
Investment Advisory Agreements between the Trust and SIMC and SIMC and the
Sub-Advisers with respect to the Funds of the Trust. In preparation for these
meetings, the Board requests and reviews a wide variety of materials provided by
SIMC and the Sub-Advisers, including information about SIMC's and the
Sub-Advisers' affiliates, personnel and operations. The Board also receives
extensive data provided by third parties. This information is in addition to the
detailed information about the Funds that the Board reviews during the course of
each year, including information that relates to Fund operations and Fund
performance. The Trustees also receive a memorandum from Fund counsel and
independent counsel to the Independent Trustees regarding the responsibilities
of Trustees in connection with their consideration of whether to approve the
Trust's Investment Advisory Agreements. Finally, the Independent Trustees
receive advice from independent counsel to the Independent Trustees, meet in
executive session outside the presence of Fund management and participate in
question and answer sessions with representatives of SIMC and the Sub-Advisers.

Specifically, the Board requested and received written materials from SIMC and
the Sub-Advisers regarding: (a) the quality of SIMC's and the Sub-Advisers'
investment management and other services; (b) SIMC's and the Sub-Advisers'
investment management personnel; (c) SIMC's and the Sub-Advisers' operations and
financial condition; (d) SIMC's and the Sub-Advisers' brokerage practices
(including any soft dollar arrangements) and investment strategies; (e) the
level of the advisory fees that SIMC and the Sub-Advisers charge the Funds
compared with the fees each charge to comparable mutual funds; (f) the Funds'
overall fees and operating expenses compared with similar mutual funds; (g) the
level of SIMC's and the Sub-Advisers' profitability from their Fund-related
operations; (h) SIMC's and the Sub-Advisers' compliance systems; (i) SIMC's and
the Sub-Advisers' policies on and compliance procedures for personal securities
transactions; (j) SIMC's and the Sub-Advisers' reputation, expertise and
resources in domestic and/or international financial markets; and (k) the Funds'
performance compared with similar mutual funds.

Board of Trustees Considerations in Approving the Advisory and Sub-Advisory
Agreements (Unaudited) (Concluded)

At the December 7-8, 2006, March 14, 2007, June 28-29, 2007 and September 19-20,
2007 meetings of the Board of Trustees, the Trustees, including a majority of
the Independent Trustees, approved the Investment Advisory Agreements and
approved the selection of SIMC and the Sub-Advisers to act in their respective
capacities for the Funds. The Board's approval was based on its consideration
and evaluation of a variety of specific factors discussed at the meetings and at
prior meetings, including:

o the nature, extent and quality of the services provided to the Funds under
  the Investment Advisory Agreements, including the resources of SIMC and the
  Sub-Advisers and their affiliates dedicated to the Funds;

o the Funds' investment performance and how it compared to that of other
  comparable mutual funds;

o the Funds' expenses under each Investment Advisory Agreement and how those
  expenses compared to those of other comparable mutual funds;

o the profitability of SIMC and the Sub-Advisers and their affiliates with
  respect to the Funds, including both direct and indirect benefits accruing to
  SIMC and the Sub-Advisers and their affiliates; and

o the extent to which economies of scale would be realized as the Funds grow
  and whether fee levels in the Investment Advisory Agreements reflect those
  economies of scale for the benefit of Fund investors.

NATURE, EXTENT AND QUALITY OF SERVICES. The Board of Trustees considered the
nature, extent and quality of the services provided by SIMC and the Sub-Advisers
to the Funds and the resources of SIMC and the Sub-Advisers and their affiliates
dedicated to the Funds. In this regard, the Trustees evaluated, among other
things, SIMC's and the Sub-Advisers' personnel, experience, track record and
compliance program. The Trustees found the level of SIMC's professional staff
and culture of compliance satisfactory. Following evaluation, the Board
concluded that, within the context of its full deliberations, the nature, extent
and quality of services provided by SIMC and the Sub-Advisers to the Funds and
the resources of SIMC and the Sub-Advisers and their affiliates dedicated to the
Funds supported renewal of the Investment Advisory Agreements.

FUND PERFORMANCE. The Board of Trustees considered Fund performance in
determining whether to renew the Investment Advisory Agreements. Specifically,
the Trustees considered the Funds' performance relative to their peer groups and
appropriate indices/benchmarks, in light of total return, yield and market
trends. As part of this review, the Trustees considered the composition of each
peer group and selection criteria. In evaluating performance, the Trustees
considered both market risk and shareholder risk expectations for the Funds. The
Trustees found Fund performance satisfactory, and where performance was below
the benchmark, the Trustees were satisfied that appropriate steps were being
taken. Following evaluation, the Board concluded that, within the context of its
full deliberations, the performance of the Funds supported renewal of the
Investment Advisory Agreements.

FUND EXPENSES. With respect to the Funds' expenses under the Investment Advisory
Agreements, the Trustees considered the rate of compensation called for by the
Investment Advisory Agreements and the Funds' net operating expense ratio in
comparison to those of other comparable mutual funds. The Trustees also
considered information about average expense ratios of comparable mutual funds
in the Funds' respective peer groups. The Trustees further considered the fact
that the comprehensive fee analysis either showed that the various fees were
below average or that there was a reasonable basis for the fee level. Finally,
the Trustees considered the effects of SIMC's voluntary waiver of management and
other fees and the Sub-Advisers' fees to prevent total Fund expenses from
exceeding a specified cap and that SIMC and the Sub-Advisers, through waivers,
have maintained the Funds' net operating expenses at competitive levels for
their respective distribution channels. Following evaluation, the Board
concluded that, within the context of its full deliberations, the expenses of
the Funds are reasonable and supported renewal of the Investment Advisory
Agreements.

240         SEI Institutional Managed Trust / Annual Report / September 30, 2007



PROFITABILITY. With regard to profitability, the Trustees considered all
compensation flowing to SIMC and the Sub-Adviser and their affiliates, directly
or indirectly. The Trustees considered whether the varied levels of compensation
and profitability under the Investment Advisory Agreements and other service
agreements were reasonable and justified in light of the quality of all services
rendered to the Funds by SIMC and the Sub-Advisers and their affiliates. The
Trustees found that profitability was reasonable and that the margin was not
increasing despite growth in assets. When considering the profitability of the
Sub-Advisers, the Board took into account the fact that the Sub-Advisers are
compensated by SIMC, and not by the Funds directly, and such compensation with
respect to any Sub-Adviser reflects an arms-length negotiation between the
Sub-Adviser and SIMC. Based on this evaluation, the Board concluded that, within
the context of its full deliberations, the profitability of SIMC and the
Sub-Advisers are reasonable and supported renewal of the Investment Advisory
Agreements.

ECONOMIES OF SCALE. The Trustees considered the existence of any economies of
scale and whether those were passed along to the Funds' shareholders through a
graduated investment advisory fee schedule or other means, including any fee
waivers by SIMC and its affiliates. Based on this evaluation, the Board
concluded that, within the context of its full deliberations, the Funds obtain
reasonable benefit from economies of scale.

Based on the Trustees' deliberation and their evaluation of the information
described above, the Board, including all of the Independent Trustees,
unanimously approved the continuation of the Investment Advisory Agreements and
concluded that the compensation under the Investment Advisory Agreements is fair
and reasonable in light of such services and expenses and such other matters as
the Trustees considered to be relevant in the exercise of their reasonable
judgment. In the course of their deliberations, the Trustees did not identify
any particular information that was all-important or controlling.

Notes:
    (1)  Audit fees include amounts related to the audit of the registrant's
         annual financial statements and services normally provided by the
         accountant in connection with statutory and regulatory filings.

(e)(1)   All requests or applications for services to be provided by the
         independent auditor shall be submitted to the Chief Financial Officer
         ("CFO") of the Funds and must include a detailed description of the
         services proposed to be rendered. The Fund's CFO will determine whether
         such services (1) require specific pre-approval, (2) are included
         within the list of services that have received the general pre-approval
         of the Audit Committee or (3) have been previously pre-approved in
         connection with the independent auditor's annual engagement letter for
         the applicable year or otherwise.



Requests or applications to provide services that require specific pre-approval
by the Audit Committee will be submitted to the Audit Committee by the CFO. The
Audit Committee will be informed by the CFO on a quarterly basis of all services
rendered by the independent auditor. The Audit Committee has delegated specific
pre-approval authority to either the Audit Committee Chair or financial expert,
provided that the estimated fee for any such proposed pre-approved service does
not exceed $100,000 and any pre-approval decisions are reported to the Audit
Committee at its next regularly scheduled meeting.

All services to be provided by the independent auditor shall be provided
pursuant to a signed written engagement letter with the Funds, the investment
advisor or applicable control affiliate (except that matters as to which an
engagement letter would be impractical because of timing issues or because the
matter is small may not be the subject of an engagement letter) that sets forth
both the services to be provided by the independent auditor and the total fees
to be paid to the independent auditor for those services.

In addition, the Audit Committee has determined to take additional measures on
an annual basis to meet its responsibility to oversee the work of the
independent auditor and to assure the auditor's independence from the Funds,
such as reviewing a formal written statement from the independent auditor
delineating all relationships between the independent auditor and the Funds, and
discussing with the independent auditor its methods and procedures for ensuring
independence.

(e)(2)   Percentage of fees billed applicable to non-audit services pursuant to
waiver of pre-approval requirement were as follows:

            ------------------------- ------------- ------------
                                          2007         2006
            ------------------------- ------------- ------------
             Audit-Related Fees            0%           0%
            ------------------------- ------------- ------------
             Tax Fees                      0%           0%
            ------------------------- ------------- ------------
             All Other Fees                0%           0%
            ------------------------- ------------- ------------


(f)      Not Applicable.

(g)(1) The aggregate non-audit fees and services billed by KPMG for the fiscal
year 2007 and fiscal year 2006 were $269,515 and $277,130, respectively.
Non-audit fees consist of SAS No. 70 review of fund accounting and
administration operations, attestation report in accordance with Rule 17 Ad-13,
agreed upon procedures report over certain internal controls related to
compliance with federal securities laws and regulations and tax consulting
services for various service affiliates of the registrant.

(h)      During the past fiscal year, Registrant's principal accountant provided
certain non-audit services to Registrant's investment adviser or to entities
controlling, controlled by, or under common control with Registrant's investment
adviser that provide ongoing services to Registrant that were not subject to
pre-approval pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X.
The audit committee of Registrant's Board of Trustees reviewed and considered
these non-audit services provided by Registrant's principal accountant to
Registrant's affiliates, including whether the provision of these non-audit
services is compatible with maintaining the principal accountant's independence.
