MANAGEMENT’S DISCUSSION AND ANALYSIS OF FUND PERFORMANCE

SEI INSTITUTIONAL INVESTMENTS TRUST — MAY 31, 2010 (Unaudited)

Large Cap Fund

 

I. Objective:

The Large Cap Fund (the “Fund) seeks to provide long-term growth of capital and income.

II. Multi-Manager Approach Statement:

The Fund uses a multi-manager approach, relying on a number of sub-advisors with differing investment approaches to manage portions of the Fund’s portfolio under the general supervision of SEI Investments Management Corp. (SIMC). The Fund utilized the following sub-advisers as of May 31, 2010: Quantitative Management Associates, LLC, Legg Mason Capital Management Inc., Delaware Investments Company, Neuberger Berman Management LLC, Aronson + Johnson + Ortiz L.P. and LSV Asset Management. For the fiscal year ended May 31, 2010, Neuberger Berman Management LLC was added to the Fund, while Intech Investment Management, LLC and Goldman Sachs Asset Management were terminated.

III. Market Commentary:

The U.S. equity market, as measured by the Russell 1000 Index, gained 22.33% during the fiscal year ended May 31, 2010. After a historic fall in 2008, equity markets staged a strong rebound in 2009 off the heels of unprecedented global intervention by governments and central banks. Stocks and sectors that suffered the steepest declines in the year prior drove market returns in 2009. More specifically, smaller-cap and lower-quality names, most of which were assumed to be insolvent, posted significant gains.

For the fiscal year, value stocks outperformed their growth counterparts in the large-cap universe. All ten Global Industry Classification Standard (GICS) sectors posted positive performance during the period. A renewed confidence in economic recovery revived investors’ willingness for risk taking. The Consumer Discretionary sector was the best-performing sector, up 44%, followed by Industrials and Information Technology. Conversely, more defensive sectors, which performed well during the year before, lagged the broad market. Utilities, Consumer Staples and Healthcare names failed to keep pace with the market, as investors sought higher returns in riskier assets. Energy shares were a surprise during the fiscal year. Widely thought of as a cyclical sector, Energy was the worst-performing sector during the period. Exxon Mobil and Chevron, both significant constituents of the sector, trailed the benchmark. From a factor perspective, small-size and value factors, both traditional and relative, were the best-performing factors. Earnings and price momentum factors performed worst.

IV. Return vs. Benchmark:

For the fiscal year ended May 31, 2010, the Fund underperformed the Russell 1000 Index, returning 20.05% versus the index return of 22.33%.

 

V. Fund Attribution:

Although it posted a strong absolute return, the Fund lagged its benchmark, mostly due to an underweight to Financials and poor stock selection in Information Technology. The sudden rebound in banks and real estate caught managers short-handed, as many had been focusing instead on the less risky industry of diversified financials, as these names were more insulated from the recent credit crisis. On the Technology side, many software and hardware names that did well in the early part of 2009 had a reversal during the subsequent rally and continued to lag in 2010. In general, the Fund’s managers hold higher-quality names and thus did not participate in the rebound experienced by stocks that were priced for bankruptcy. The Fund benefited from an underweight to one of the defensive sectors, Consumer Staples, which lagged during the fiscal year ended May 31, 2010. A similar story can be told for the Energy sector, which the Fund also underweighted and which has come down in valuation over the past year.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FUND PERFORMANCE

SEI INSTITUTIONAL INVESTMENTS TRUST — MAY 31, 2010 (Unaudited)

Large Cap Diversified Alpha Fund

 

I. Objective:

The Large Cap Diversified Alpha Fund (the “Fund”) seeks to provide long-term growth of capital and income.

II. Multi-Manager Approach Statement:

The Fund uses a multi-manager approach, relying on a number of sub-advisors with differing investment approaches to manage portions of the Fund’s portfolio under the general supervision of SEI Investments Management Corp. (SIMC). The Fund utilized the following sub-advisers as of May 31, 2010: Quantitative Management Associates, LLC, Analytic Investors, LLC, Intech Investment Management, LLC, Legg Mason Capital Management, Inc., Delaware Management Company and Aronson + Johnson + Ortiz L.P. There were no changes to the portfolio in the fiscal year.

III. Market Commentary:

The U.S. equity market, as measured by the Russell 1000 Index, gained 22.33% during the fiscal year ended May 31, 2010. After a historic fall in 2008, equity markets staged a strong rebound in 2009 off the heels of unprecedented global intervention by governments and central banks. Stocks and sectors that suffered the steepest declines in the year prior drove market returns in 2009. More specifically, smaller-cap and lower-quality names, most of which were assumed to be insolvent, posted significant gains.

For the fiscal year, value stocks outperformed their growth counterparts in the large-cap universe. All ten Global Industry Classification Standard (GICS) sectors posted positive performance during the period. A renewed confidence in economic recovery revived investors’ willingness for risk taking. The Consumer Discretionary sector was the best-performing sector, up 44%, followed by Industrials and Information Technology. Conversely, more defensive sectors, which performed well during the year before, lagged the broad market.

From a factor perspective, small-size and value factors, both traditional and relative, were the best-performing factors. Earnings and price momentum factors performed worst.

IV. Return vs. Benchmark:

For the fiscal year ended May 31, 2010, the Fund outperformed the Russell 1000 Index, returning 22.61% versus the index return of 22.33%.

 

V. Fund Attribution:

The Fund delivered strong performance, with the LIBOR Plus portfolio and an allocation to Consumer Staples as major contributors. On the Technology side, many software and hardware names that did well in the early part of 2009 had a reversal during the subsequent rally and continued to lag in 2010. In general, the Fund’s managers hold higher-quality names and thus did not participate in the bounce experienced by many stocks that were priced for bankruptcy. Positioning in Financials also detracted from performance. The sudden rebound in real estate caught managers short-handed, as many had instead been focusing on the less risky industry of diversified financials, where companies were more insulated from the recent credit crisis. On the bright side, strong stock selection in the Healthcare sector boosted returns, especially once investors came back to the sector after decisions were finalized surrounding potential government regulation. In addition, the Fund benefited from an underweight to the Energy sector, which had come down in valuation over the past year.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FUND PERFORMANCE

SEI INSTITUTIONAL INVESTMENTS TRUST — MAY 31, 2010 (Unaudited)

Large Cap Disciplined Equity Fund

 

I. Objective:

The Large Cap Disciplined Equity Fund (the “Fund”) seeks to provide capital appreciation.

II. Multi-Manager Approach Statement:

The Fund uses a multi-manager approach, relying on a number of sub-advisors with differing investment approaches to manage portions of the Fund’s portfolio under the general supervision of SEI Investments Management Corp. (SIMC). The Fund utilized the following sub-advisers as of May 31, 2010: Quantitative Management Associates, LLC, Analytic Investors, Inc., INTECH Investment Management, LLC, Massachusetts Financial Services Company and Lazard Asset Management LLC. For the one-year period ending May 31,2010, Lazard Asset Management LLC was added to the Fund.

III. Market Commentary:

The U.S. equity market, as measured by the Russell 1000 Index, gained 22.33% during the fiscal year ending May 31, 2010. After a historic fall in 2008, equity markets staged a strong rebound in 2009 off the heels of unprecedented global intervention by governments and central banks. Stocks and sectors that suffered the steepest declines in the year prior drove market returns in 2009. More specifically, smaller-cap and lower-quality names, most of which were assumed to be insolvent, posted significant gains.

For the fiscal year, value stocks outperformed their growth counterparts in the large-cap universe. All ten Global Industry Classification Standard (GICS) sectors posted positive performance during the period. A renewed confidence in economic recovery revived investors’ willingness for risk taking. The Consumer Discretionary sector was the best-performing sector, up 44%, followed by Industrials and Information Technology. Conversely, more defensive sectors, which performed well during the year before, lagged the broad market. Telecommunications, Healthcare and Materials names failed to keep pace with the market, as investors sought higher returns in riskier assets. Energy shares were a surprise during the fiscal year. Widely thought of as a cyclical sector, Energy was the worst-performing sector during the period. Exxon Mobil and Chevron, both significant constituents of the sector, trailed the benchmark. From a factor perspective, small size and expected growth were the best-performing factors. Momentum factors for both earnings and prices were negative.

IV. Return vs. Benchmark:

For the fiscal year ended May 31, 2010, the Fund outperformed the S&P 500 Index, returning 22.32% versus the index return of 20.99%.

 

V. Fund Attribution:

After a difficult time for quantitative managers, the tide turned during the past year for all but the factor rotation manager. The latter manager had a difficult time during the choppy markets, as its process relies on a trending market with a clear direction to add value. A decrease in the Chicago Board Options Exchange Volatility Index (VIX), a measure of implied volatility in S&P 500 Index options that is also known as the “fear index,” benefited the volatility capture manager for most of the period, as did the out-performance of smaller stocks, which the manager is typically biased towards. Investors began rewarding value factors once more—a boon to the traditional quantitative managers in the Fund—although this was dampened by the headwind from lower-quality names (usually underweighted by quantitative managers) outperforming during the market rally. The Fund’s hybrid manager did especially well, namely due to holdings in the Consumer Discretionary sector. The Libor Plus portfolio added significant alpha to the Fund as well, as credit spreads have continued to narrow.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FUND PERFORMANCE

SEI INSTITUTIONAL INVESTMENTS TRUST — MAY 31, 2010 (Unaudited)

Large Cap Index Fund

 

I. Objective:

The Large Cap Index Fund (the “Fund”) seeks to provide investment results that correspond to the aggregate price and dividend performance of the securities in the Russell 1000 Index.

II. Manager Approach Statement:

The Fund uses a sub-advisor to manage the Fund under the supervision of SEI Investments Management Corporation (SIMC). Currently, the sub-advisor is State Street Global Advisors. There were no manager changes during the period.

III. Market Commentary:

The U.S. equity market, as measured by the Russell 1000 Index, gained 22.33% during the fiscal year ended May 31, 2010. After a historic fall in 2008, equity markets staged a strong rebound in 2009 off the heels of unprecedented global intervention by governments and central banks. Stocks and sectors that suffered the steepest declines in the year prior drove market returns in 2009.

IV. Return vs. Benchmark:

For the fiscal year ended May 31, 2010, the Fund outperformed the Russell 1000 Index, returning 22.34% versus the benchmark return of 22.33%.

V. Fund Attribution:

Incremental excess return was generated due to cash flows. As an index fund, performance is designed to track that of the index.

Small Cap Fund

 

I. Objective:

The Small Cap Fund (the “Fund”) seeks to provide capital appreciation.

II. Multi-Manager Approach Statement:

The Fund uses a multi-manager approach, relying upon a number of sub-advisers with differing investment philosophies to manage portions of the Fund’s portfolio under the general supervision of SEI Investments Management Corporation (“SIMC”). The Fund utilized the following sub-advisers as of May 31, 2010: AQR Capital Management, LLC, Artisan Partners Limited Partnership, Janus Capital Management, Inc., Lee Munder Capital Group LLC, Los Angeles Capital Management & Equity Research, Inc., LSV Asset Management, Oppenheimer Capital, LC, Robeco Investment Management, Inc., Security Capital Research and Management, Inc. and Wellington Management Company, LLP.

For the fiscal year ended May 31, 2010, BlackRock Capital Management, Inc., McKinley Capital Management, Inc., Neuberger Berman Management, LLC, PanAgora Asset Management, Inc and Martingale Asset Management, L.P. were removed from the Fund. AQR Capital Management, LLC was added during the period.

III. Market Commentary:

The U.S. small-cap equity market, as measured by the Russell 2000 Index, gained over 33% during the fiscal year ended May 31, 2010. After small-cap stocks lost nearly half of their value in 2008 and early 2009, U.S. Small Cap stocks turned decisively positive in March 2009 as the extreme fear over the state of the U.S. and world financial systems subsided. An extended rally followed as investors discounted government intervention and became hopeful of an economic recovery, albeit a moderate one. From a factor perspective, price and earnings momentum performed very poorly for the fiscal year. Value, small market cap and low price were the best factors as the companies investors believed to be the most likely bankruptcy candidates during the downturn tended to lead the market during the rebound.

IV. Return vs. Benchmark:

For the fiscal year ended May 31, 2010, the Fund outperformed the Russell 2000 Index, returning 35.32% versus the index return of 33.62%.

 

V. Fund Attribution:

The majority of out-performance occurred in the third quarter of 2009, as the initial rally from the March 2009 low extended, and an underweight to the lagging banking industry added to performance. The Fund posted solid performance on a relative basis, principally due to stock selection within the Financials sector, particularly the real estate investment trust (REIT) industry. Strong stock selection in the Industrials sector contributed meaningfully as well. The core quantitative managers outperformed for the period, as factor returns began to trend and value factors saw positive returns. The value managers also contributed to performance, with a majority of them outperforming the Russell 2000 Value Index.

Small/Mid Cap Equity Fund

 

I. Objective:

The Small/Mid Cap Equity Fund (the “Fund”) seeks to provide long-term capital appreciation.

II. Multi-Manager Approach Statement:

The Fund uses a multi-manager approach, relying upon a number of sub-advisers with differing investment philosophies to manage portions of the Fund’s portfolio under the general supervision of SEI Investments Management Corporation (“SIMC”). The Fund utilized the following sub-advisers as of May 31, 2010: Integrity Asset Management, LLC, Janus Capital Management, Inc., Lee Munder Capital Group LLC, Los Angeles Capital Management & Equity Research, Inc., LSV Asset Management, PanAgora Asset Management, Inc., Security Capital Research and Management, Inc., Wellington Management Company, LLP and Wells Capital Management, Inc.

For the fiscal year ended May 31, 2010, BlackRock Capital Management, Inc. and Martingale Asset Management, L.P. were removed from the Fund. Wellington’s Small Cap Growth product was added during the period.

III. Market Commentary:

The U.S. small/mid cap equity market, as measured by the Russell 2500 Index, gained over 35% during the fiscal year ended May 31, 2010. After small- and mid-cap stocks lost nearly half of their value in 2008 and early 2009, these markets turned decisively positive in March 2009 as the extreme fear over the state of the U.S. and world financial systems subsided. An extended rally followed as investors discounted government intervention and became hopeful of an economic recovery, albeit a moderate one. From a factor perspective, price and earnings momentum performed very poorly for the fiscal year. Value, small market cap and low price were the best factors as the companies investors believed to be the most likely bankruptcy candidates during the downturn tended to lead the market during the rebound.

IV. Return vs. Benchmark:

For the fiscal year ended May 31, 2010, the Fund outperformed the Russell 2500 Index, returning 35.79% versus the index return of 35.07%.

 

V. Fund Attribution:

The majority of out-performance occurred in the third quarter of 2009 as markets continued to rally off of March lows. The Fund posted solid performance on a relative basis, largely due to stock selection within the Financials sector, particularly the REIT industry. Strong stock selection in the Materials sector was also beneficial. From a style perspective, the Fund’s value managers contributed to performance, with each outperforming the Russell 2000 Value Index, and Wells Capital, added in 2008, contributed to performance as the best-performing growth manager over the period.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FUND PERFORMANCE

SEI INSTITUTIONAL INVESTMENTS TRUST — MAY 31, 2010 (Unaudited)

U.S. Managed Volatility Fund

 

I. Objective:

The U.S. Managed Volatility Fund (the “Fund”) seeks to provide capital appreciation with less volatility than the broad U.S. equity markets.

II. Multi-Manager Approach Statement:

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 SIMC. The Fund utilized the following sub-advisors as of May 31, 2010: Aronson + Johnson + Ortiz, LP and Analytic Investors LLC. No manager changes were made during the period.

III. Market Commentary:

Economic recovery and excess liquidity prompted a sharp market rebound. Cyclical sectors, which previously experienced the heaviest declines, led the rally. Consumer Discretionary and Industrials posted the best returns, with the defensive Utilities and Telecommunications sectors lagging the broader market.

Companies that seemed to have a questionable chance for survival in 2008 were rewarded the most. These stocks generally had high levels of debt and a high beta, or more sensitivity to the movements in the broader market. High-beta names outperformed the low-beta ones overall.

May 2010 saw an increase in risk aversion compared to the last 12 months. Concerns over Southern European sovereign debt, an overheating Chinese property market and possibly the economy, as well as consequences of BP’s oil spill for the entire industry caused investors to seek refuge in the safer Consumer Staples, Telecommunications and Utilities sectors.

IV. Return vs. Benchmark:

For the fiscal year ended May 31, 2010, the Fund underperformed the Russell 3000 Index, returning 21.12% versus the index return of 23.20%.

 

V. Fund Attribution:

The Fund’s underperformance was primarily driven by its defensive stance, which is required to achieve the primary objective of lowering volatility and providing downside protection to investors. In fact, the volatility reduction goal was comfortably achieved. For the fiscal year ended May 31, 2010, the Fund realized an annualized standard deviation of 14% (daily frequency) as compared to the benchmark’s results of 19%.

To achieve its intended low risk profile, the managers target lower-beta, lower-risk names with stable earnings streams and lower leverage ratios. In the early stages of market recovery, such positioning prevented the Fund from fully participating in the rally. As low-beta stocks lagged their high-beta counterparts by over 18%, this has had a major negative allocation effect. After adjusting for the beta positioning, stock selection was strong. From a more traditional sector perspective, the Fund’s overweight to the defensive Consumer Staples, Utilities, and Healthcare sectors detracted significantly.

The Fund uses a multi-manager approach, relying upon a number of sub-advisors with differing investment philosophies to manage portions of the Fund’s portfolio under the general supervision of SEI Investments Management Corporation (“SIMC”). The Fund utilizes the following sub-advisers as of May 31, 2010: Acadian Asset Management, LLC, AXA Rosenberg Investment Management, LLC, Declaration Management and Research, LLC, INTECH Investment Management, LLC, Neuberger Berman Management, LLC, Quantitative Management Associates, LLC, and Schroder Investment Management North America, Inc.

For the fiscal year ended May 31, 2010, Neuberger Berman Management and Schroder Investment Management were added to the Fund; McKinley Capital Management, Principal Global Investors, and Wellington Management Company were terminated.

III. Market Commentary:

Global equity markets continued their tumble from 2008 well into the first quarter of 2009. However, hopeful signs emerged in March 2009 as global stimulus efforts began to take effect. Investors started to feel more confident about a global economic recovery and their appetite for risk returned, fueling a strong rally through the end of the year. Starting in March, stocks that had suffered the most during the credit crisis led the rally. This was reflected in the leadership by the cheapest stocks, particularly as measured by prices relative to book values (assets minus liabilities). Companies that had the highest levels of debt also outperformed the index. In the third quarter, earnings releases for many companies were better than expected, pushing prices higher. However, as the rally matured, investors began to favor companies with higher-quality balance sheets and opportunities to gain market share. In the first five months of 2010, global equity markets were down overall as macroeconomic events, which included the European sovereign debt crisis, a slowdown in Chinese growth, and the oil spill in the Gulf of Mexico, took center stage.

IV. Return vs. Benchmark:

For the fiscal year ended May 31, 2010, the Fund outperformed the MSCI EAFE Index, returning 6.68% versus the index return of 6.38%.

V. Fund Attribution:

The Fund outperformed the benchmark, driven primarily by positive stock selection by the sub-advisors; however, allocation also contributed to performance. From a regional perspective, in addition to positive stock selection, the Fund’s underweight allocation to Europe ex-UK was beneficial as the region struggled with mounting

sovereign debt issues and fears of contagion. On the other hand, the Fund’s underweight allocation and stock selection in Pacific ex-Japan detracted from performance. Australia, the largest constituent in Pacific ex-Japan, was one of the hottest markets during the period and the Fund’s underweight allocation detracted. From a sector perspective, performance was diverse, favoring neither cyclical nor defensive sectors. Consumer Discretionary stocks performed the best, with automobile companies dominating positive performance. Industrial and Health Care detracted due to weak stock selection for the time period.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FUND PERFORMANCE

SEI INSTITUTIONAL INVESTMENTS TRUST — MAY 31, 2010 (Unaudited)

World Equity Ex-US Fund

 

I. Objective:

The objective of the World Equity Ex-US Fund (the “Fund”) is to provide capital appreciation.

II. Multi-Manager Approach Statement:

The Fund uses a multi-manager approach, relying upon a number of sub-advisors with differing investment philosophies to manage portions of the Fund’s portfolio under the general supervision of SEI Investments Management Corporation (“SIMC”). The Fund utilizes the following sub-advisors as of May 31, 2010: Acadian Asset Management, Inc., Artisan Partners Limited Partnership, Declaration Management & Research LLC, McKinley Capital Management, LLC, NFJ Investment Group LLC, Principal Global Investors, LLC, Quantitative Management Associates, LLC and Thornburg Investment Management LLC.

For the fiscal year ended May 31, 2010, NFJ Investment Group LLC and Thornburg Investment Management LLC were added to the Fund; Wellington Management Company, LLC, AXA Rosenberg Investment Management, LLC, INTECH Investment Management, LLC and Rexiter Capital Management Limited were terminated.

III. Market Commentary:

Global equity markets continued their tumble from 2008 well into the first quarter of 2009. However, hopeful signs emerged in March 2009 as global stimulus efforts began to take effect. Investors started to feel more confident about a global economic recovery and their appetite for risk returned, fueling a strong rally through the end of the year.

Companies that had the highest levels of debt also outperformed the index. In the third quarter, earnings releases for many companies were better than expected, pushing prices higher. However, as the rally matured, investors began to favor companies with higher-quality balance sheets and opportunities to gain market share.

In the first five months of 2010, global equity markets were down overall as macroeconomic events, which included the European sovereign debt crisis, a slowdown in Chinese growth and the oil spill in the Gulf of Mexico, took center stage. For the time period, emerging markets outperformed developed markets and sector performance was mixed.

IV. Return vs. Benchmark:

For the fiscal year ended May 31, 2010, the Fund outperformed the MSCI All Country World Ex-U.S. Index, returning 10.74% versus the index return of 10.63%.

 

V. Fund Attribution:

The Fund outperformed the benchmark, driven primarily by positive stock selection by the sub-advisors; however, allocation also contributed to performance. From a regional perspective, emerging markets outperformed developed markets, so the Fund’s overweight allocation to emerging markets benefitted performance. Brazilian and Mexican stocks were especially strong. The Fund’s underweight allocation to Europe Ex-U.K. was beneficial, as the region struggled with mounting sovereign debt issues and fears of contagion. On the other hand, the Fund’s underweight allocation and stock selection in Pacific Ex-Japan detracted from performance. Australia, the largest constituent in Pacific Ex-Japan, was one of the hottest performers among the developed markets, and the Fund’s underweight positioning detracted from performance.

From a sector perspective, performance was diverse, favoring neither cyclical nor defensive sectors. Consumer Discretionary stocks performed the best, with automobile companies dominating positive performance. Telecommunication Services was the largest detractor with wireless services stocks down the most.

IV. Return vs. Benchmark:

For the fiscal year ended May 31, 2010, the Fund outperformed the MSCI All Country World Ex-U.S. Index, returning 11.00% versus the index return of 10.63%.

 

V. Fund Attribution:

The Fund outperformed the benchmark, driven primarily by positive stock selection by the sub-advisors; however, allocation was slightly beneficial. From a regional perspective, stock selection was especially strong in Europe Ex-U.K. despite the region’s sovereign debt crisis. Stock selection in emerging markets was also positive, with Latin American stocks posting the largest returns. On the other hand, the Fund’s underweight allocation and stock selection in Pacific Ex-Japan detracted from performance. Australia, the largest constituent in Pacific Ex-Japan, was one of the hottest performers among the developed markets, and the Fund’s underweight positioning and stock selection detracted. From a sector perspective, performance was diverse across cyclical and defensive sectors. Industrials, Information Technology and Energy were the best performers, while Telecommunication Services and Materials lagged the index the most.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FUND PERFORMANCE

SEI INSTITUTIONAL INVESTMENTS TRUST — MAY 31, 2010 (Unaudited)

Enhanced LIBOR Opportunities Fund

 

I. Objective:

The Enhanced LIBOR Opportunities Fund (the “Fund”) seeks to provide capital appreciation and income.

II. Multi-Manager Approach Statement:

The Fund uses a multi-manager approach, relying on a number of sub-advisors with differing investment approaches to manage portions of the Fund’s portfolio under the general supervision of SEI Investments Management Corp. (SIMC). The Fund utilizes the following sub-advisors as of May 31, 2010: Declaration Management & Research LLC, UBS Global Asset Management (Americas), Inc., Wellington Management Company, LLP and Ares Management LLC. No changes were made to the Fund during the period.

III. Market Commentary:

Fixed-income market conditions for the fiscal year ended May 31, 2010 reflected a dramatic recovery from the crisis conditions of 2008, including the bankruptcy of Lehman Brothers. The period was characterized by an increased investor appetite for risk that drove powerful rallies in most of the non-Treasury sectors in the market. The catalyst for the market recovery was a series of government programs designed to improve credit availability, which included the Term Asset-Backed Securities Lending Facility (TALF), the Public-Private Investment Program (PPIP) and a $1.25 trillion purchase program of agency mortgage-backed securities (MBS) by the U.S. Federal Reserve (Fed). The Fed’s purchase program brought MBS spreads and mortgage rates to historic lows. The TALF and PPIP programs helped drive strong performance in the non-agency MBS market, including commercial MBS, and the asset-backed securities market. The corporate bond market was supported by stabilizing economic conditions, lower default rates and improved market liquidity. The senior bank loan market also saw stellar returns, as fundamental credit conditions continued to improve and the technical environment remained supportive of higher loan prices, with demand outpacing supply. The strong market recovery was interrupted in the spring of 2010, as the European sovereign credit crisis triggered a modest flight to quality that served to bring Treasury yields back to the lower end of their trading range. Despite the more recent caution displayed by market participants, the rallies in the non-Treasury sectors provided very strong performance for the fixed income markets for the twelve-month period.

 

IV. Return vs. Benchmark:

For the fiscal year ended May 31, 2010, the Fund outperformed the Bank of America (“BofA”) Merrill Lynch 3-Month London Interbank Offered Rate (LIBOR) Constant Maturity Index, returning 12.66% versus the index return of 0.39%.

V. Fund Attribution:

During the fiscal year ended May 31, 2010, the Fund’s large allocation to non-Treasury sectors outperformed—particularly the portfolio’s allocations to non-agency mortgage-backed securities, commercial mortgage-backed securities and senior bank loans.

Core Fixed Income Fund

 

I. Objective:

The Core Fixed Income Fund (the “Fund”) seeks to provide current income consistent with the preservation of capital.

II. Multi-Manager Approach Statement:

The Fund uses a multi-manager approach, relying on a number of sub-advisors with differing investment approaches to manage portions of the Fund’s portfolio, under the general supervision of SEI Investments Management Corp. (SIMC). The Fund utilized the following sub-advisors as of May 31, 2010: Trust Company of the West (formerly Metropolitan West Asset Management), J.P. Morgan Investment Management, Inc., Western Asset Management Company, Wells Capital Management, Inc. and Jennison Associates LLC. During the fiscal year ended May 31, 2010, Jennison Associates LLC was added to the Fund.

III. Market Commentary:

Fixed-income market conditions for the fiscal year ended May 31, 2010 reflected a dramatic recovery from the crisis conditions of 2008 and the post-Lehman bankruptcy. The period was characterized by an increased investor appetite for risk that drove powerful rallies in most of the non-Treasury sectors of the market. The catalyst for the market recovery was a series of government programs designed to improve credit availability. These programs included the Term Asset-Backed Securities Loan Facility (TALF), the Public-Private Investment Program (PPIP) and a $1.25 trillion purchase program of agency mortgage-backed securities (MBS) by the U.S. Federal Reserve (Fed). The Fed’s purchase program brought MBS spreads and mortgage rates to historic lows. The TALF and PPIP programs helped drive strong performance in the non-agency MBS market (including commercial MBS) and the asset-backed securities market. The corporate market was supported by stabilizing economic conditions, lower default rates and improved market liquidity. The strong market recovery was interrupted in the spring of 2010, as the European sovereign credit crisis triggered a modest flight to quality that served to bring Treasury yields back to the lower end of their trading range. Despite this more recent market caution, the rallies in the non-Treasury sectors provided very strong performance for fixed-income markets during the twelve-month period.

IV. Return vs. Benchmark:

For the fiscal year ended May 31, 2010, the Fund outperformed the Barclays Capital U.S. Aggregate Bond Index, returning 15.34% versus the index return of 8.42%.

V. Fund Attribution:

The Fund’s overweight positions in corporate bonds, non-agency MBS and commercial MBS were the key drivers of performance. In addition, the Fund entered the year with a positive bias towards agency MBS due to the Federal Reserve’s purchase program, but as

prices relative to Treasuries continued to climb, managers moved to an increasingly underweight position. As the Fed discontinued these purchases, prices relative to Treasuries weakened modestly, and the Fund gradually added exposure toward the end of the measurement period. Duration exposure did not have a meaningful impact on performance, as managers chose to utilize their risk budgets on securities within the non-Treasury sectors.

Specifically, an overweight to corporate bonds, especially those issued by large-cap financial firms, generated significant out-performance relative to Treasuries. The steep yield curve combined with improved access to the capital markets allowed the largest of the U.S. banking institutions to repair their balance sheets and return to profitability throughout the year. Non-agency mortgages recovered dramatically as the forced selling resulting from ratings downgrades and the unwinding of large levered positions abated. The announcement and implementation of PPIP and TALF during the year restored confidence in the market, thereby allowing private capital to flow back into the securitized markets. Finally, the Fund’s overweight to commercial MBS contributed to performance, as these securities posted the largest out-performance versus Treasuries of any sector within the Barclays Capital U.S. Aggregate Bond Index.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FUND PERFORMANCE

SEI INSTITUTIONAL INVESTMENTS TRUST — MAY 31, 2010 (Unaudited)

High Yield Bond Fund

 

I. Objective:

The High Yield Bond Fund (the “Fund”) seeks to maximize total return.

II. Multi-Manager Approach Statement:

The Fund uses a multi-manager approach, relying on a number of sub-advisors with differing investment approaches to manage portions of the Fund’s portfolio under the general supervision of SEI Investments Management Corp. (SIMC). The Fund utilizes the following sub-advisers as of May 31, 2010: Ares Management, LLC, Brigade Capital Management, LLC, Delaware Management Company, Guggenheim Partners, LLC, J.P. Morgan Investment Management, Inc., and SEI Structured Credit. During the one-year period ended May 31, 2010, the Fund did not make any manager changes.

III. Market Commentary:

For the fiscal year ended May 31, 2010, the high-yield market, as measured by the Bank of America Merrill Lynch U.S. High Yield Master II Constrained Index, returned 29.91%. Credit quality spreads tightened 473 basis points (bps) to finish the period at 698 bps, down significantly from the peak of 2,168 basis points reached in December 2008. The Moody’s U.S. issuer-default rate fell from 10.86% to 7.91% over the fiscal year, after peaking at an all-time high of 14.51% in November 2009. Default rates are projected to continue their descent to 2.7% by the end of 2010. The significant amount of new issuance over the past 12 months, particularly for refinancing purposes, has improved the creditworthiness of many high-yield companies. Also putting downward pressure on the default rate is the fact that a large number of defaults occurred in the first half of 2009, therefore moving out of the 12-month window. Issuance in the primary market has been extremely robust over the period, with $247.5 billion coming to market, the second largest 12-month stretch on record (12 months ended April 30, 2010 saw the highest volume). The technical condition of the market was positive, as high-yield mutual funds saw $18.1 billion of inflows during the period, although May 2010 was a weak month due to European sovereign debt concerns; $3.5 billion exited funds, which reversed most of the YTD inflows. For the fiscal year, an increase in investor risk appetites and improved market

liquidity led to strong returns across all quality segments, but lower- quality credits outperformed, with CCCs up 60.72%, followed by Bs up 23.21%, and BBs up 23.15%.

The best-performing sectors were the higher-beta segments of the market, such as the Financial-related and Technology sectors. Insurance, Real Estate, Financial Services and Banking all outperformed the market, with the first three mentioned generating returns greater than twice the index gain. AIG, which has subsidiaries that operate in the Insurance and Financial Services sectors, had the largest impact on returns, while Realogy and iStar Financial boosted the performance in the Real Estate space. AIG was up on optimism about the insurer’s success in raising capital by selling off business units. AIG was scheduled to sell its Asian Life Unit to Prudential for $35.5B (Prudential pulled out of this deal in June, 2010), and to sell American Life Insurance Company (Alico) to MetLife for $15.5B, as they work to repay TARP money to the U.S. government. Technology companies did well over the year also, as investors moved into these high-growth companies as confidence in the economic recovery increased. Semiconductor firms were particularly strong, as many of these firms cut staff in 2008/2009, which has resulted in better earnings as chip sales for personal computers and cell phones, the biggest market drivers, are projected to grow in the low-to-mid-teens in 2010.

The Utilities and Telecommunications sectors lagged the overall high-yield market over the year, producing the lowest total returns among the sectors in the index. These sectors are both considered to be more defensive in nature and thus would be expected to under-perform in an environment where high-risk securities rally sharply. More specifically, electric generation companies within the Utilities sector were negatively impacted by numerous issues. Weak demand for power and natural gas hurt this sector, as well as unimpressive earnings results that reflected a poor operating environment and bleak future outlook for the sector. Uncertainty surrounding future environmental regulations and commodity prices remains. Within telecom, wireless companies have suffered from increased competition within the industry, which has created both pricing pressures and subscriber losses, two factors that have led to weaker earnings across many companies in the sector.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FUND PERFORMANCE

SEI INSTITUTIONAL INVESTMENTS TRUST — MAY 31, 2010 (Unaudited)

High Yield Bond Fund (Concluded)

 

IV. Return vs. Benchmark:

For the fiscal year ended May 31, 2010, the Fund outperformed the Bank of America (“BofA”) Merrill Lynch U.S. High Yield Master II Constrained Index, returning 37.60% versus the index return of 29.91%.

V. Fund Attribution:

The Fund’s allocation to CLOs and other structured investments outperformed the high-yield market, enhancing relative performance. The fundamental picture of the CLO marketplace has improved drastically due to the continued upturn in the high-yield loan and bond markets, the slowing pace of defaults/downgrades, and the ability of borrowers to successfully amend their credit agreements. Additionally, the technical picture has been a large driver of the rally, with the prospects for new issuance dim and a significant amount of money on the sidelines waiting to invest.

Another contributor to out-performance was the Fund’s underweight to and strong security selection within the Energy sector. An underweight to gas distribution companies’ debt boosted returns, since these firms were negatively impacted by low natural gas prices and a poor outlook for the industry. Security selection was strong within the integrated energy industry due to an overweight to ethanol producer Aventine Renewable Energy. Aventine emerged from Chapter 11 bankruptcy during the year and has also benefited from rumors that the EPA will boost the limit for blending ethanol with gasoline from 10% to 12-15%, which would increase demand for ethanol.

Security selection in the Media and Insurance sectors detracted from performance during the period. Poor security selection in the Media sector was largely impacted by an underweight to Clear Channel Communications, as the broadcasting company’s bonds benefited from improving financial results, the successful execution of several exchange offers for existing debt, and several new issues. These actions were taken to address immediate liquidity concerns and they dramatically improved the financial health of the company. Within the Insurance sector, an underweight to AIG hampered returns, as the company’s bonds rallied after it was able to raise a substantial amount of capital through both the new-issue market and asset sales, as mentioned above in the Market Commentary section.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FUND PERFORMANCE

SEI INSTITUTIONAL INVESTMENTS TRUST — MAY 31, 2010 (Unaudited)

Long Duration Fund

 

I. Objective:

The Long Duration Fund (the “Fund”) seeks to provide return characteristics similar to those of high-quality corporate bonds with a duration range of 9 to 14 years.

II. Multi-Manager Approach Statement:

The Fund uses a multi-manager approach, relying on a number of sub-advisors with differing investment approaches to manage portions of the Fund’s portfolio under the general supervision of SEI Investments Management Corp. (SIMC). The Fund utilizes the following sub-advisors as of May 31, 2010: Trust Company of the West (formerly Metropolitan West Asset Management LLC), Jennison Associates LLC and Income Research & Management. For the fiscal year ended May 31, 2010, Jennison Associates LLC and Income Research & Management were added to the Fund.

III. Market Commentary:

Fixed-income market conditions for the fiscal year ended May 31, 2010 reflected a dramatic recovery from the crisis conditions of 2008, including the bankruptcy of Lehman Brothers. The period was characterized by an increased investor appetite for risk that drove powerful rallies in most of the non-Treasury sectors in the market. The catalyst for the market recovery was a series of government programs designed to improve credit availability, which included the Term Asset-Backed Securities Lending Facility (TALF), the Public-Private Investment Program (PPIP) and a $1.25 trillion purchase program of agency mortgage-backed securities (MBS) by the U.S. Federal Reserve (Fed).

The TALF and PPIP programs helped drive strong performance in the non-agency MBS market, including commercial MBS, and the asset-backed securities market. The corporate bond market was supported by stabilizing economic conditions, lower default rates and improved market liquidity. The strong market recovery was interrupted in the spring of 2010, as the European sovereign credit crisis triggered a modest flight to quality that served to bring Treasury yields back to the lower end of their trading range. Despite this more recent market caution, the rallies in the non-Treasury sectors provided very strong performance for the fixed-income markets for the one-year period.

IV. Return vs. Benchmark:

For the fiscal year ended May 31, 2010, the SIIT Long Duration Fund returned 18.11% compared to 15.11% for its benchmark, the Barclays Long U.S. Government/Credit Index.

 

V. Fund Attribution:

The Fund’s out-performance came from its overweight exposure to the corporate bond sector. The corporate overweight was focused on the Financials sector, which led the strong rally in the corporate market. The modest drop in intermediate- and longer-term Treasury yields served to support the very strong absolute return of the Fund.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FUND PERFORMANCE

SEI INSTITUTIONAL INVESTMENTS TRUST — MAY 31, 2010 (Unaudited)

Emerging Markets Debt Fund

 

I. Objective:

The Emerging Markets Debt Fund (the “Fund”) seeks to maximize total return.

II. Multi-Manager Approach Statement:

The Fund uses a multi-manager approach, relying on a number of sub-advisors with differing investment approaches to manage portions of the Fund’s portfolio under the general supervision of SEI Investments Management Corp. (SIMC). The Fund utilized the following sub-advisors as of May 31, 2010: Ashmore Investment Management Limited, ING Investment Management Advisors, B.V. and Stone Harbor Investment Partners L.P. For the fiscal year ended May 31, 2010, no sub-advisor changes were made in the Fund.

III. Market Commentary:

The credit crisis abated and risk appetite amongst investors returned very quickly, which led to emerging markets debt posting its strongest annual performance since 1996. The market returned 29% in 2009 and carried the momentum into 2010 with a 3.55% return through the end of May. Spreads began the fiscal year at 478 basis points and tightened by as much as 222 basis points over U.S. Treasuries before widening in April and May to 338 basis points on broader risk aversion emanating from the Greek and eurozone sovereign debt crisis.

The fundamentals of emerging-markets debt remain strong and are supported by various factors. Stable and rising commodity prices, rising foreign currency reserves, declining debt levels and less political turbulence all contribute to a favorable outlook for the asset class. These factors have contributed to a substantial increase in credit-rating upgrades, with only a handful of downgrades during the last 12 months. Positive surprises to economic growth across the broader emerging markets universe have been supportive, while election results and unorthodox policy changes (which have rattled emerging markets in the past) have been conducted in more democratic ways with less violence and protest.

 

In addition to solid fundamentals, technical factors greatly contributed to performance for the period. The ability of emerging markets to weather the credit crisis of 2008 better than other spread sectors caught the attention of both new and existing investors. As a result, inflows into the asset class amounted to $54 billion for the period. Inflows are rising and becoming increasingly diversified, especially with more instrument selection coming from the growing local and corporate sectors of the market. As investors poured historically high amounts of money into emerging-markets debt, emerging-market issuers took advantage of lower financing rates and issued record amounts of bonds to meet the rising demand for emerging-market debt assets. In 2009 alone, emerging-market issuers raised $210 billion via new external debt issuance and have sold $105 billion through the first five months of 2010. With another $90 billion still in the pipeline for the remainder of the year, technicals are still expected to remain a key driver of performance going forward. The proceeds of these sales will be used for deficit funding, refinancing and infrastructure & development projects.

Central banks and local governments have done their part to improve confidence amongst investors and market participants. Fiscal policy continues to improve, and although monetary policy has been accommodative and successful in implementing counter-cyclical measures during the last 12 months, policymakers will be challenged going forward as inflationary pressures, stimulus unwinding, financial reforms and the fiscal crisis in Europe pose potential risks that could hinder growth. The outlook for emerging markets is positive, and fundamentals have not yet been threatened by any potential risks. Emerging countries are expected to grow approximately 6.2% in 2010, while the developed world is expected to grow by less than 3%. Problems in Europe and the rest of the developed world should only benefit the asset class as investors look for alternative opportunities.

IV. Return vs. Benchmark:

For the fiscal year ended May 31, 2010, the Fund outperformed the J.P. Morgan Emerging Markets Bond Index (EMBI) Global Diversified Index, returning 24.93% versus the index return of 17.85%.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FUND PERFORMANCE

SEI INSTITUTIONAL INVESTMENTS TRUST — MAY 31, 2010 (Unaudited)

Emerging Markets Debt Fund (Concluded)

 

V. Fund Attribution:

Security selection in Argentina contributed to positive relative performance for the period. The country had been plagued by political problems and fiscal concerns prior to and during the credit crisis that nearly led to a default. Fortunately, rising commodity prices led to strong export revenues, and the country’s endless commitment to comforting creditors and servicing debt was fulfilled via multiple debt swaps and an eventual decision to proceed with what the country hopes to be the final restructuring of past defaulted debt. Markets reacted favorably to the news and Argentina finished the period returning 69%, one of the top-performing countries in emerging-markets debt universe. An overweight to Russia added to out-performance, as rising oil prices helped support a country with one of the worst primary fiscal balances in emerging markets. Additionally, the government increased support to the struggling banking sector while inflation continued to slow, allowing rate cuts to follow and help revive the economy. Russia is better positioned to service its debt than its emerging-markets peers, and its rising level of foreign currency reserves has improved its financial flexibility. Allocations to local currency debt in Brazil also added to relative performance, as the country was marginally impacted by the credit crisis. The country’s diversified export base benefited from rising commodities, foreign currency reserves continued to rise, and loan growth and consumption helped drive its first-quarter 2010 gross domestic product growth to an annualized rate of 11.25%, one of the highest in the world.

The Fund’s underweight in Belize detracted from relative performance, as bonds returned 100% for the period. Belize makes up a very small portion of the index and generates most of its growth from agriculture and tourism. The country is a low-quality credit and rallied with other risky assets. An underweight in Ghana also detracted from performance. Similar to Belize, Ghana is a lower-quality country and also one of the smallest countries in the index. The country carries a higher beta than the index and outperformed the market on improved sentiment and a rally in commodity prices. Fund managers chose not to allocate to Belize or Ghana because the risk/reward opportunities were more attractive in more fiscally sound countries.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FUND PERFORMANCE

SEI INSTITUTIONAL INVESTMENTS TRUST — MAY 31, 2010 (Unaudited)

Real Return Fund

 

I. Objective:

The Real Return Fund (the “Fund”) seeks to provide total return exceeding the rate of inflation.

II. Multi-Manager Approach Statement:

The Fund uses a sub-adviser to manage the Fund under the supervision of SEI Investments Management Corporation (SIMC). Currently, the sub-advisor is Wellington Management Company, LLC. There were no manager changes during the period.

III. Market Commentary:

Fixed-income market conditions for the fiscal year ended May 31, 2010 reflected a dramatic recovery from the crisis conditions of 2008, including the bankruptcy of Lehman Brothers. The period was characterized by an increased investor appetite for risk that drove powerful rallies in most of the non-Treasury sectors in the market. The catalyst for the market recovery was a series of government programs designed to improve credit availability, which included the Term Asset-Backed Securities Lending Facility (TALF), the Public-Private Investment Program (PPIP) and a $1.25 trillion purchase program of agency mortgage-backed securities (MBS) by the U.S. Federal Reserve (Fed). The Fed’s purchase program brought MBS spreads and mortgage rates to historic lows. The TALF and PPIP programs helped drive strong performance in the non-agency MBS market, including commercial MBS, and the asset-backed securities market. These actions helped stabilize economic conditions, which in turn supported the Treasury Inflation-Protected Securities (TIPS) market, as there were higher inflation expectations among investors and improved market liquidity. The strong market recovery was interrupted in the spring of 2010, as the European sovereign credit crisis triggered a modest flight to quality that served to bring Treasury yields back to the lower end of their trading range. Despite the more recent caution displayed by market participants, the rally in TIPS provided strong performance for the for the twelve month period.

IV. Return vs. Benchmark:

For the fiscal year ended May 31, 2010, the Fund returned 5.70% compared to 5.63% for its benchmark. The Fund’s adviser believes the Barclays 1-5 Year U.S. TIPS Index better represents the Fund’s investment opportunities.

 

V. Fund Attribution:

The Fund’s out-performance was a result of its tactical and timely allocation to nominal Treasuries. As Treasuries were the main beneficiaries of the recent flight to quality, this allocation helped the Fund outperform its benchmark. In addition, the modest drop in TIPS yields served to support the absolute return of the Fund.

1. ORGANIZATION

SEI Institutional Investments Trust (the “Trust”) was organized as a Massachusetts business trust under a Declaration of Trust dated March 1, 1995. The Trust commenced operations on June 14, 1996.

The Trust is registered under the Investment Company Act of 1940, as amended, as an open-end investment company with 20 registered funds: Large Cap, Large Cap Diversified Alpha, Large Cap Disciplined Equity, Large Cap Index, Strategic U.S. Large Cap Equity, Small Cap, Small/Mid Cap Equity, U.S. Managed Volatility, International Equity, World Equity Ex-US, Screened World Equity Ex-US, Emerging Markets Equity, Global Equity, Enhanced LIBOR Opportunities, Core Fixed Income, High Yield Bond, Long Duration, Emerging Markets Debt, Real Return and Dynamic Asset Allocation Funds (each a “Fund,” collectively, the “Funds”) each of which are diversified Funds with the exception of the Emerging Markets Debt Fund. The Trust is registered to offer Class A shares of all Funds. The assets of each Fund are segregated, and a shareholder’s interest is limited to the Fund in which shares are held. The Trust’s prospectus provides a description of each Fund’s investment objectives, policies, and strategies.

As of May 31, 2010, the Dynamic Asset Allocation, Strategic U.S. Large Cap Equity, Emerging Markets Equity and Global Equity 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 U.S. generally accepted accounting principles (“GAAP”), requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities as of 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. Debt securities are priced based upon valuations provided by independent, third-party pricing agents, if available. 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 acquired with remaining maturities of sixty days or less may be valued

at their amortized cost, which approximates market value. The prices for foreign securities are reported in local currency and converted to U.S. dollars using currency exchange rates. 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 Trust’s Board of Trustees. The Trust’s Fair Value Procedures are implemented through a Fair Value Committee (the “Committee”) designated by the Trust’s 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 a 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 a 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 a Fund calculates net asset value, the adviser or sub-adviser may request that a Fair Value Committee Meeting be called. In addition, the Trust’s 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 a 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.

The International Equity, World Equity Ex-US and Screened World Equity Ex-US Funds that hold international securities also use a third-party fair valuation vendor. The vendor provides a fair value for foreign securities held by these funds based on certain factors and method-

ologies (involving, generally, tracking valuation correlations between the U.S. market and each non-U.S. security). Values from the fair value vendor are applied in the event that there is a movement in the U.S. market that exceeds a specific threshold that has been established by the Committee. The Committee has also established a “confidence interval” which is used to determine the level of historical correlation between the value of a specific foreign security and movements in the U.S. market before a particular security will be fair valued when the threshold is exceeded. In the event that the threshold established by the Committee is exceeded on a specific day, these funds that hold international securities will value the non-U.S. securities within that fund that exceed the applicable “confidence interval” based upon the adjusted prices provided by the fair valuation vendor.

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.

In accordance with GAAP, Fair Value is defined as the price that a Fund would receive upon selling an investment in a timely transaction to an independent buyer in the principal or most advantageous market of the investment. A three tier hierarchy has been established to maximize the use of observable and minimize the use of unobservable inputs and to establish classification of fair value measurements for disclosure purposes. Inputs refer broadly to the assumptions that market participants would use in pricing an asset. Inputs may be observable or unobservable. Observable inputs are inputs that reflect the assumptions market participants would use in pricing the asset or liability based on market data obtained from sources independent of the reporting entity. Unobservable inputs are inputs that reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability based on the best information available in the circumstances.

The three-tier hierarchy of inputs is summarized in the three broad Levels listed below:

 

Level 1 — quoted prices in active markets for identical investments
Level 2 — other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risks, etc.)
Level 3 — significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments)

The valuation techniques used by the Funds to measure fair value during the fiscal year ended May 31, 2010 maximized the use of observable inputs and minimized the use of unobservable inputs.

For the fiscal year ended May 31, 2010, there have been no significant changes to the Trust’s fair valuation methodologies.

Security Transactions and Investment Income — Security transactions are recorded on the trade date. Cost used in determining net

realized capital gains and losses on the sale of securities is determined on the basis of specific identification. Dividend income and expense is recognized on the ex-dividend date, and interest income or expense is recognized using the accrual basis of accounting.

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 — A Fund may agree to purchase securities from financial institutions subject to the seller’s agreement to repurchase them at a mutually agreed upon date and price. It is the Fund’s policy that repurchase agreements are fully collateralized by U.S. Treasury and Government Agency securities. All collateral is held by the Fund’s custodian bank or a bank with which the custodian bank has entered into a subcustodian agreement, or is segregated in the Federal Reserve Book Entry System. In connection with transactions in repurchase agreements, if the seller defaults and the value of the collateral declines, or if the seller enters an insolvency proceeding, realization of the collateral by the Fund may be delayed or limited.

Reverse Repurchase Agreements — To the extent consistent with its Investment Objective and Strategies, a 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, those Funds use of the proceeds under the reverse repurchase 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 outstanding reverse repurchase agreements as of May 31, 2010.

Expenses — Expenses that are directly related to a Fund are charged directly to that Fund. Other operating expenses of the Funds are prorated to the Funds on the basis of relative net assets.

Foreign Currency Translation — The books and records of the Funds investing in international securities 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


 

148    SEI Institutional Investments Trust / Annual Report / May 31, 2010


Table of Contents

 

(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 — To the extent consistent with its Investment Objective and Strategies, a Fund may enter into forward foreign currency contracts as hedges against either specific transactions, fund positions or anticipated fund positions. All commitments are marked-to-market daily at the applicable foreign exchange rate, and any resulting unrealized gains or losses are recorded currently. The Fund realizes 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. A Fund 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 Summary Schedule of Investments/Schedule of Investments or the Statement of Assets and Liabilities.

Futures Contracts — All Funds, with the exception of the High Yield Bond and Real Return Funds, utilized futures contracts during the fiscal year ended May 31, 2010. These Funds’ investments in futures contracts are designed to enable the Funds to more closely approximate the performance of their benchmark indices. To the extent consistent with its Investment Objective and Strategies, a 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 Funds record 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 a 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 Summary Schedule of Investments/Schedule of Investments or the Statement of Assets and Liabilities.

Options/Swaptions Writing/Purchasing — To the extent consistent with its Investment Objective and Strategies, a Fund may invest in financial options/swaptions contracts for the purpose of hedging its existing portfolio securities, or securities that a Fund intends to purchase, against fluctuations in fair market value caused by changes in prevailing market interest rates. A Fund may also invest in financial option/swaption contracts to enhance its 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. The Core Fixed Income Fund had options contracts as of May 31, 2010, as disclosed in the Fund’s Schedule of Investments.

The risk in writing a call option/swaption is a Fund may give up the opportunity for profit if the market price of the security increases. The risk in writing a put option/swaption is a Fund 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 a Fund may 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 could exceed amounts disclosed on the Summary Schedule of Investments/Schedule of Investments or the Statement of Assets and Liabilities.

Securities Sold Short — As consistent with each Fund’s investment objectives, a Fund may engage in short sales. Short sales are transactions under which a Fund sells a security it does not own. To complete such a transaction, a Fund must borrow the security to make delivery to the buyer. That Fund then is obligated to replace the security borrowed by purchasing the security at the market price at the time of the replacement. The price at such time may be more or less than the price at which the security was sold by a Fund. Until the

security is replaced, a Fund is required to pay the lender amounts equal to any dividends or interest that accrue during the period of the loan. Dividends and interest are shown as an expense for financial reporting purposes. To borrow the security, a Fund also may be required to pay a premium, which would decrease proceeds of the security sold. The proceeds of the short sale are retained by the broker, to the extent necessary to meet margin requirements, until the short position is closed out. A gain, limited to the price at which a Fund sold the security short, or a loss, unlimited in size, will be recognized upon the close of a short sale.

Until a Fund closes its short position or replaces the borrowed security, that Fund will: (a) maintain a segregated account containing cash or liquid securities at such a level that (i) the amount deposited in the account plus the amount deposited with the broker as collateral will equal the current value of the security sold short; and (ii) the amount deposited in the segregated account plus the amount deposited with the broker as collateral will not be less than the market value of the security at the time the security was sold short, or (b) otherwise cover a Fund’s short positions. As of May 31, 2010, none of the Funds held any short positions.

Swap Agreements — A Fund’s investments in swap contracts is mainly used as an efficient means to take and manage risk in the portfolio, including interest rate risk, credit risk and overall yield sensitivity. 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. Credit default swaps involve the periodic payment by a Fund or counterparty of interest 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. 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 (London Interbank Offered Rate) or some other form of index 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 a Fund’s exposure to interest rates. Payments received or made are recorded as realized gains or losses. A 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. In connection with swap agreements, securities/cash may be set aside as collateral by a 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; protect a Fund’s value from changes in interest rates; or 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 unrealized gains or losses 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.

This risk is mitigated by having a master netting arrangement between a Fund and the counterparty and by having the counterparty post collateral to cover a Fund’s exposure to the counterparty. See Note 3 for further details.

Forward Treasury Commitments — A Fund may invest in commitments to purchase U.S. Treasury securities on an extended settlement basis. Such transactions involve the commitment to purchase a security with payment and delivery taking place in the future, sometimes a month or more after the transaction date. The Funds account for such transactions as purchases and sales and record an unrealized gain or loss each day equal to the difference between the cost of the purchase commitment and the current market value. Realized gains or losses are recorded upon closure or settlement of such commitments. No interest is earned prior to settlement of the transaction. These instruments are subject to market fluctuation due to changes in interest rates and the market value at the time of settlement could be higher or lower than the purchase price. A Fund may incur losses due to changes in the value of the underlying treasury securities from interest rate fluctuations or as a result of counterparty nonperformance.

Delayed Delivery Transactions — To the extent consistent with its Investment Objective and Strategies, a Fund may purchase or sell securities on a when-issued or delayed delivery basis. These transactions involve a commitment by those Funds to purchase or sell securities for a predetermined price or yield, with payment and delivery taking place beyond the customary settlement period. When purchasing a security on a delayed delivery basis, that 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

Table of Contents

 

determining its net asset value. Those Funds 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 those Funds have sold a security on a delayed delivery basis, that Fund does not participate in future gains and losses with respect to the security.

Loan Participations and Brady Bonds — To the extent consistent with its Investment Objective and Strategies, a Fund may invest in U.S. dollar-denominated fixed- and floating-rate loans (“Loans”) arranged through private negotiations between a foreign sovereign entity and one or more financial institutions (“Lenders”). The Fund invests in such Loans in the form of participations in Loans (“Participations”) or assignments of all or a portion of Loans from third parties. Participations typically result in this Fund having a contractual relationship only with the Lenders, not with the sovereign borrowers. This Fund has the right to receive payments of principal, interest and any fees to which it is entitled from the Lender selling the Participation and only upon receipt by the Lender of the payments from the borrower. In connection with purchasing Participations, the Fund generally has no right to enforce compliance by the borrower with the terms of the loan agreement relating to the Loan, nor any rights of set-off against the borrower, and the Fund will not benefit directly from any collateral supporting the Loan in which it has purchased the Participation. As a result, the Fund assumes the credit risk of both the borrower and the Lender that is selling the Participation.

Certain debt obligations, customarily referred to as “Brady Bonds,” are created through the exchange of existing commercial bank loans to foreign entities for new obligations in connection with debt restructuring under a plan introduced by former U.S. Secretary of the Treasury Nicholas F. Brady. Brady Bonds have only been issued since 1989, and, accordingly, do not have a long payment history. They are issued by governments that may have previously defaulted on the loans being restructured by the Brady Bonds, so they are subject to the risk of default by the issuer. They may be fully or partially collateralized or uncollateralized and issued in various currencies.

Collateralized Debt Obligations — A Fund 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 security. 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 a Fund 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 not 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) a Fund 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.

Dividends and Distributions to Shareholders — Dividends from net investment income are declared and paid to shareholders quarterly for the Large Cap, Large Cap Diversified Alpha, Large Cap Disciplined Equity, Large Cap Index, Small Cap, Small/Mid Cap Equity, U.S. Managed Volatility, Enhanced LIBOR Opportunities and Emerging Markets Debt Funds; declared daily and paid monthly for the Core Fixed Income, Long Duration and High Yield Bond Funds; and declared and paid at least annually for the International Equity, World Equity Ex-US, Screened World Equity Ex-US and Real Return Funds. Dividends and distributions are recorded on the ex-dividend date. Any net realized capital gains will be distributed at least annually by the Funds.

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 a Fund. Valuations of illiquid securities may differ significantly from the values that would have been used had an active market value for these securities existed.

Investments in Real Estate Investment Trusts (“REITs”) — 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. CREDIT DERIVATIVES

A Fund enters into credit default swaps to simulate long and short bond positions that are either unavailable or considered to be less attractively priced in the bond market. A Fund uses these swaps to reduce risk where a Fund has exposure to the issuer, or to take an active long or short position with respect to the likelihood of an event of default. The reference obligation of the swap can be a single issuer, a “basket” of issuers, or an index. The underlying referenced assets are corporate debt, sovereign debt and asset-backed securities.

The buyer of a credit default swap is generally obligated to pay the seller a periodic stream of payments over the term of the contract in return for a contingent payment upon the occurrence of a credit event with respect to an underlying reference obligation. Generally, a credit event for corporate or sovereign reference obligations means bankruptcy, failure to pay, obligation acceleration, repudiation/moratorium or restructuring. For credit default swaps on asset-backed securities, a

credit event may be triggered by events such as failure to pay principal, maturity extension, rating downgrade or write-down.

If a Fund is a seller of protection, and a credit event occurs, as defined under the terms of that particular swap agreement, a Fund will generally either (i) pay to the buyer an amount equal to the notional amount of the swap and take delivery of the referenced obligation, other deliverable obligations, or underlying securities comprising a referenced index or (ii) pay a net settlement amount in the form of cash or securities equal to the notional amount of the swap less the recovery value of the referenced obligation or underlying securities comprising a referenced index.

If a Fund is a buyer of protection and a credit event occurs, as defined under the terms of that particular swap agreement, a Fund will either (i) receive from the seller of protection an amount equal to the notional amount of the swap and deliver the referenced obligation, other deliverable obligations or underlying securities comprising the referenced index or (ii) receive a net settlement amount in the form of cash or securities equal to the notional amount of the swap less the recovery value of the referenced obligation or underlying securities comprising the referenced index. Recovery values are assumed by market makers considering either industry standard recovery rates or entity specific factors and considerations until a credit event occurs. If a credit event has occurred, the recovery value is determined by a facilitated auction whereby a minimum number of allowable broker bids, together with a specified valuation method, are used to calculate the settlement value.

Certain Funds are party to International Swap Dealers Association, Inc. Master Agreements (“ISDA Master Agreements”). These agreements are with select counterparties and they govern transactions,

including certain over-the-counter derivative and foreign exchange contracts, entered into by the Funds and the counterparty.


 

As of May 31, 2010, the Core Fixed Fund is the buyer (“receiving protection”) on a total notional amount of $63.9 million, and the Core Fixed and Long Duration Funds are the sellers (“providing protection”) on a total notional amount of $75.0 million and $1.2 million, respectively. The notional amounts of the swaps are not recorded in the financial statements; however the notional amounts approximate the maximum potential amount of future payments that the Fund could be required to make if the Fund was the sellers of protection and a credit event were to occur. Those credit default swaps (“CDS”) for which the Fund is providing protection at balance sheet date are summarized as follows:

8. 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 GAAP. 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.

During the fiscal year ended May 31, 2010, the Large Cap, U.S. Managed Volatility, Core Fixed Income, Long Duration and Real Return Funds utilized $7,522,945, $1,283,308, $31,257,517, $837,977 and $2,962,680, respectively, of capital loss carryforwards, to offset capital gains.

For Federal income tax purposes, the cost of securities owned at May 31, 2010, and the net realized gains or losses on securities sold for the period were not materially different from amounts reported for financial reporting purposes. These differences are primarily due to investments in partnerships and 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 aggregate gross unrealized appreciation and depreciation on total investments held by the Funds at May 31, 2010, was as follows:

Management has analyzed the Fund’s tax position taken on federal income tax returns for all open tax years and has concluded that as of May 31, 2010, no provision for income tax would be required in the Fund’s financial statements. The Fund’s federal and state income and federal excise tax returns for tax years for which the applicable statutes of limitations have not expired are subject to examination by the Internal Revenue Service and state departments of revenue.

9. CONCENTRATION/RISKS

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

The market values of the Core Fixed Income, Long Duration and High Yield Bond Funds’ investments may 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.

The International Equity, World Equity Ex-US, Screened World Equity Ex-US and Emerging Markets Debt Funds concentrate their investments in securities of foreign issuers in various countries. These investments may involve certain considerations and risks not typically associated with investments in the United States, as a result of, among other factors, the possibility of future political and economic developments and the level of governmental supervision and regulation of securities markets in the respective countries.

10. IN-KIND TRANSFERS OF SECURITIES

During the fiscal year ended May 31, 2010, the Large Cap Fund, Large Cap Disciplined Equity Fund and Small Cap Fund issued shares of beneficial interest in exchange for securities. These securities were transferred at their current value on the date of such transactions.

11. 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 between 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 fluctuations 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 the SEI Liquidity Fund L.P., and the Fund bears all of the gains and losses on such investment. There is no guarantee that these investments will not lose value.

12. SUBSEQUENT EVENTS

Management has evaluated the need for disclosures and/or adjustments resulting from subsequent events through the date the financial statements were issued. Based on this evaluation, no adjustments were required to the financial statements as of May 31, 2010.

13. OTHER MATTERS

Due to volatility in the fixed income and equity markets, the market value of a Fund’s holdings may be materially different than shown in the Summary Schedule of Investments/Schedule of Investments (“SOI”). The values shown in the SOIs were the market values as of May 31, 2010 and do not reflect any market events after May 31, 2010.

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.

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 May 31, 2010, by correspondence with the custodian and brokers or 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 Investments Trust as of May 31, 2010, the results of their operations for the year then ended, the changes in their net assets for each of the years in the two-year period then ended, and the financial highlights for each of the years or periods in the five-year period then ended, in conformity with U.S. generally accepted accounting principles.

Disclosure of Fund Expenses (Unaudited)

May 31, 2010

 

All mutual funds have operating expenses. As a shareholder of a 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 fund’s gross income and directly reduce your final investment return. These expenses are expressed as a percentage of the fund’s average net assets; this percentage is known as the 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:

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 the 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.”

Hypothetical 5% return. This section helps you compare your Fund’s costs with those of other mutual funds. It assumes that the 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 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.

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

 

SEI Institutional Investments 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.

At the December 9-10, 2009 and March 24-25, 2010 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:

 

 

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;

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

 

 

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

 

 

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

 

 

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

 

 

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 comparative 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.

Profitability. With regard to profitability, the Trustees considered all compensation flowing to SIMC and the Sub-Advisers 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 is 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.

(e)(1) The Registrant’s Audit Committee has adopted and the Board of Trustees has ratified an Audit and Non-Audit Services Pre-Approval Policy (the “Policy”), which sets forth the procedures and the conditions pursuant to which services proposed to be performed by the independent auditor of the Registrant may be pre-approved.

The Policy provides that all requests or applications for proposed services to be provided by the independent auditor must be submitted to the Registrant’s Chief Financial Officer (“CFO”) and must include a detailed description of the services proposed to be rendered. The 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 pursuant to the Policy; or (3) have been previously pre-approved in connection with the independent auditor’s annual engagement letter for the applicable year or otherwise. In any instance where services require pre-approval, the Audit Committee will consider whether such services are consistent with SEC’s rules and whether the provision of such services would impair the auditor’s independence.

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 experts, 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.

Services that have received the general pre-approval of the Audit Committee are identified and described in the Policy. In addition, the Policy sets forth a maximum fee per engagement with respect to each identified service that has received general pre-approval.

All services to be provided by the independent auditor shall be provided pursuant to a signed written engagement letter with the Registrant, 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 Registrant, such as reviewing a formal written statement from the independent auditor delineating all relationships between the independent auditor and the Registrant, 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:

 

     Fiscal 2010   Fiscal 2009

Audit-Related Fees

   0%   0%

Tax Fees

   0%   0%

All Other Fees

   0%   0%

(f) Not Applicable.


Table of Contents

(g) The aggregate non-audit fees and services billed by KPMG for the fiscal years 2010 and 2009 were $244,500 and $234,500, respectively. Non-audit fees consist of SAS No. 70 review of fund accounting and administration operations, attestation report in accordance with Rule 17Ad-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.

Table of Contents

The Registrant has a standing Nominating Committee (the “Committee”) currently consisting of the Independent Trustees. The Committee is responsible for evaluating and recommending nominees for election to the Registrant’s Board of Trustees (the “Board”). Pursuant to the Committee’s Charter, adopted on June 18, 2004, as amended, the Committee will review all shareholder recommendations for nominations to fill vacancies on the Board if such recommendations are submitted in writing and addressed to the Committee at the Registrant’s office.

 

Item 11. Controls and Procedures.

(a) The Registrant’s principal executive and principal financial officers, or persons performing similar functions, have concluded that the Registrant’s disclosure controls and procedures (as defined in Rule 30a-3(c) under the Investment Company Act of 1940 (the “1940 Act”)) are effective (except as noted below), based on the evaluation of these controls and procedures required by Rule 30a-3(b) under the 1940 Act and Rules 13a-15(b) or 15d-15(b) under the Securities Exchange Act of 1934 as of a date within 90 days of the filing date of this report.

In connection with its audit of the Registrant’s financial statements for the period ended May 31, 2010, KPMG has advised management that management did not maintain effective internal controls related to changes to security terms recorded in the accounting system which have not been authorized by management, including security interest yields in the SEI Institutional Investments Trust Emerging Markets Debt Fund. KPMG’s internal control report, which discussed this matter, is filed as an Exhibit to the Registrant’s most recent Form N-SAR.

(b) There were no significant changes in the Registrant’s internal control over financial reporting (as defined in Rule 30a-3(d) under the 1940 Act) that occurred during the last fiscal year that have materially affected, or are reasonably likely to materially affect, the Registrants internal control over financial reporting. Subsequent to the registrant’s last fiscal half-year a new control has been implemented to ensure the timely detection of changes to fixed income securities that materially impact a security’s interest yield.

 

Items 12. Exhibits.

(a)(1) Code of Ethics attached hereto.

(a)(2) A separate certification for the principal executive officer and the principal financial officer of the Registrant as required by Rule 30a-2(a) under the Investment Company Act of 1940, as amended (17 CFR 270.30a-2(a)), are filed herewith.

(b) Officer certifications as required by Rule 30a-2(b) under the Investment Company Act of 1940, as amended (17 CFR 270.30a-2(b)) also accompany this filing as an exhibit.
