How did the Fund perform in the last year?

The Fund underperformed its benchmark, the Russell 1000 Index (USD)—which tracks the performance of 1000 of the largest U.S. equity securities based on market capitalization—for the 12-month period ending May 31, 2025. Fund performance was hampered by its value tilt and preference for companies with consistent free cash flow. This resulted in underweight allocations to several strong-performing stocks within the consumer discretionary sector, particularly within the automobile industry. The Fund’s gains were concentrated in the financials and communication services sectors.

Among Fund managers, Cullen Capital Management LLC’s performance lagged the Russell 1000 Index (USD) due to its value style, its dividend orientation, and its underweight allocation to the consumer discretionary sector. LSV Asset Management underperformed due to its value orientation and underweight allocations to growth stocks including those in the information technology and consumer discretionary sectors. Copeland Capital Management, LLC lagged due to its dividend orientation, an underweight to communication services, and security selection within the consumer discretionary sector. Acadian Asset Management LLC’s outperformance was attributable to its momentum orientation, an underweight to the healthcare sector, and favorable security selection within healthcare and communication services. Fred Alger Management, LLC benefited from its momentum orientation and favorable security selection within the information technology sector. During the portion of the year in which Mar Vista Investment Partners, LLC (“Mar Vista”) was a Fund sub-adviser, its performance lagged the benchmark due to the lack of exposure to the automobile industry and security selection within the information technology and industrials sectors. During the portion of the year in which PineStone Asset Management, Inc. (“PineStone”) was a Fund manager, its performance was in line with the benchmark as its favorable security selection within the financials and consumer discretionary sectors was offset by negative security selection within healthcare.

How did the Fund perform in the last year?

The Fund modestly underperformed its primary benchmark, the S&P 500 Index (TR)—a capitalization-weighted index consisting of roughly 500 large U.S. companies that are considered representative of the broad U.S. stock market—for the 12-month period ending May 31, 2025. The Fund’s value tilt and underweight allocation to mega-cap technology stocks served as headwinds to performance, particularly in the first half of the reporting period. Fund performance was enhanced by its overweight to the financials sector and favorable stock selection in healthcare, while stock selection in the consumer discretionary sector was a detractor.

Among Fund sub-advisers, Acadian Asset Management LLC outperformed the benchmark S&P 500 Index (TR) due to its momentum (in which investors buy stocks that have shown recent price gains and sell stocks that have recently declined) orientation, an underweight allocation to the healthcare sector, and favorable security selection in the healthcare and communication services sectors. Copeland Capital Management, LLC slightly lagged the benchmark due to its dividend growth orientation, underweight to the communication services sector, and unfavorable stock selection in the consumer discretionary sector. These negative effects were partially offset by favorable stock selection in the information technology sector. Mackenzie Investments Corporation slightly underperformed due to its value tilt and unfavorable stock selection in the energy and information technology sectors. These negative effects were partially counterbalanced by favorable stock selection in the consumer staples and healthcare sectors. Brandywine Global Investment Management, LLC lagged the benchmark due to its significant value bias and underweights to the information technology and consumer discretionary sectors. PineStone Asset Management LLC’s (“PineStone”) performance was in line with that of the benchmark as positive security selection in the financials and consumer discretionary sectors was offset by adverse security selection effects in healthcare.

How did the Fund perform in the last year?

The Fund modestly underperformed its benchmark, the Russell Small Cap Completeness Index (USD) — which measures the performance of the Russell 3000 Index companies excluding S&P 500 Index constituents — for the 12-month period ending May 31, 2025. The Fund employed equity index futures to provide stock-like performance to a portion of the liquidity reserve account, which contained cash available for fund withdrawals. This weighed on the Fund’s relative performance during the reporting period.

How did the Fund perform in the last year?

The Fund outperformed its benchmark, the Russell 2000 Index (USD)—which tracks the performance of the small-cap segment of the U S. equity market—for the 12-month period ending May 31, 2025.

Most of the Fund’s outperformance over the reporting period occurred during the volatile market environment in early April 2025. Los Angeles Capital Management LLC (LA Capital) and Martingale Asset Management, L.P. (Martingale) were the top-performing sub-advisers during the period. Martingale’s low volatility-focused strategy benefited as the low volatility factor performed well. LA Capital’s strong performance was attributable mainly to positive stock selection results, especially in the information technology and energy sectors. LSV Asset Management more modestly outperformed versus the benchmark, as the value style did not experience strong performance during the period. Axiom Investors LLC and The Informed Momentum Company LLC (IMC) (fka EAM Investors, LLC) detracted from Fund performance. While these strategies benefited from the positive performance of momentum factor investing (in which investors buy stocks that have shown recent price gains and sell stocks that have recently declined) in 2024, they struggled with the rapid shift in leadership in the first quarter of 2025.

At the sector level, Fund performance benefited moderately from active sector positioning. An overweight allocation to the consumer staples and financials sectors, as well as underweights to energy and healthcare, enhanced Fund performance for the reporting period. Overall stock selection had a positive impact on Fund performance, particularly in the healthcare, financials, and energy sectors. Conversely, stock selection in industrials detracted from Fund performance.

The Fund’s higher-quality positioning generally provided a tailwind to performance as lower-quality stocks significantly lagged the Russell 2000 Index during the reporting period. Similarly, while the Fund’s bias toward the least-expensive stocks in the Index did not contribute to its outperformance for the period, its bias away from the most-expensive names bolstered performance. An overweight allocation to the momentum factor investing style also contributed positively to Fund performance.

How did the Fund perform in the last year?

The Fund underperformed its benchmark, the Russell 2000 Index (USD)—which tracks the performance of the small-cap segment of the U S. equity market—for the 12-month period ending May 31, 2025.

The Fund lost ground during the risk-on rally that gripped U.S. small-cap stocks in July 2024. This was partially offset in March and April 2025, as risk-off investor sentiment took hold amid economic uncertainty and announcements of U.S. tariffs.

Among the Fund’s sub-advisors, Los Angeles Capital Management LLC benefited from its dynamic approach (in which asset allocations and holdings are actively adjusted based on changing market conditions and trends). Stock selection within the information technology and energy sectors added to Fund performance. Leeward Investments, LLC benefited from its low volatility exposure throughout early 2025.

Copeland Capital Management, LLC detracted modestly from Fund performance. The manager struggled notably during the fourth quarter of 2024, amid a positive quarter for more speculative names in the Russell 2000 Index (USD), but rebounded during the volatility in the first several months of 2025. The Informed Momentum Company LLC (IMC) (fka EAM Investors, LLC) weighed on Fund performance to a slightly larger degree, initially benefiting from positive returns for the momentum investing style (in which investors buy stocks that have shown recent price gains and sell stocks that have recently declined) in 2024, but struggling with the shift in market leadership in 2025. Easterly Investment Partners LLC faced value style headwinds and adverse stock selection in the materials and information technology sectors.

An overweight allocation to the energy sector hampered Fund performance for the period. This was partially offset by the positive impact of an overweight to financials. Stock selection in materials, information technology, and industrials weighed on Fund performance. This was mostly offset by positive stock selection in energy and financials.

At the factor level, the Fund’s bias away from the lowest-quality stocks in the Russell 2000 Index (USD) bolstered performance, but its overweight to the least-expensive stocks in the Index was a detractor.

How did the Fund perform in the last year?

The Fund underperformed its benchmark, the Russell 2500 Index (USD)—which tracks the performance of the small- to mid-cap segment of the U.S. equity universe, commonly referred to as "smid" cap—for the 12-month period ending May 31, 2025.

The Fund declined during the more speculative environment in the fourth quarter of 2024 following the results of the U.S. presidential election in November. The Fund regained this lost ground amid the market volatility of late March and early April 2025, but manager-specific results weighed on performance again at the end of the reporting period in May.

Among the Fund’s sub-advisers, Geneva Capital Management LLC benefited from its higher-quality/low-volatility positioning in the first quarter of 2025. The manager also saw an upturn in July 2024, attributable to stock-specific results during a more beta-driven rally (beta is a quantitative measure of the volatility relative to a benchmark) for small-cap stocks. Jackson Creek Investment Advisors LLC slightly outperformed the benchmark Russell 2500 Index for the period, bolstered by its tilt toward the momentum investing style (in which investors buy stocks that have shown recent price gains and sell stocks that have recently declined).

Axiom Investors LLC detracted modestly from Fund performance for the reporting period due to style tailwinds in 2024, but struggled with the change in market leadership for the first five months of 2025. LSV Asset Management underperformed more significantly due largely to value style headwinds over the period. Copeland Capital Management, LLC was the largest detractor from Fund performance for the period, attributable mainly to weakness in the fourth quarter of 2024. This was only partially offset by positive performance for the manager’s holdings in low-volatility stocks in the first quarter of 2025.

Sector positioning modestly hampered Fund performance for the period due largely to a slight underweight to utilities. Stock selection in consumer discretionary, energy, financials, and information technology detracted from Fund performance. This was partially offset by positive stock selection in healthcare.

How did the Fund perform in the last year?

The Fund outperformed its benchmark, the Russell 3000 Index (USD)—which tracks the performance of the 3,000 largest U.S. companies representing approximately 96% of the investable U.S. equity market— for the 12-month period ending May 31, 2025.

Fund performance for the reporting period was bolstered by gains from the momentum strategy, which continued to benefit from the dominance of artificial intelligence (AI)-themed stocks. The strategy benefited from stock selection across multiple sectors, including information technology (with overweight positions in companies such as AppLovin, Guidewire, and Broadcom); consumer staples (overweighting Sprouts Farmers Market, Walmart, and Philip Morris); and healthcare (the lack of exposure to UnitedHealth Group, Merck & Co., and Gilead Sciences).

The value and low volatility strategies enhanced Fund performance for the reporting period. The value strategy was bolstered by stock selection in the healthcare sector (especially overweight allocations to Cardinal Health, Merck & Co., and Gilead Sciences), as well as stock selection in the utilities and industrials sectors. The low volatility strategy also benefited from stock selection in the healthcare sector, along with stock selection in the information technology.

The Fund’s quality strategy saw virtually flat performance during the reporting period, as investors’ attention shifted toward high-volatility, speculative stocks. In addition to the absence of holdings in strong-performing technology stocks such as Tesla and Broadcom, the was hampered by an underweight position in the financials sector (notably J.P. Morgan, Wells Fargo, and Bank of America), which benefited from a combination of expectations for Trump administration policies and stock-specific corporate earnings guidance. Stock selection in the consumer discretionary and communication services sectors also detracted from the strategy’s performance. This was partially offset by positive stock selection in the healthcare and consumer staples sectors.

How did the Fund perform in the last year?

The Fund modestly outperformed its primary benchmark, the Russell 3000 Index (USD)—which tracks the performance of the 3,000 largest U.S. companies representing approximately 96% of the investable U.S. equity market—for the 12-month period ending May 31, 2025. The Fund underperformed for the first half of the reporting period due to its low-beta exposure (beta is a quantitative measure of the volatility relative to a benchmark) and value exposure. These trends reversed in 2025 due to heightened market volatility amid uncertainty around U.S. tariff policy and concerns around artificial intelligence (AI) capital expenditures. Fund performance benefited from this market rotation due to its low-volatility bias and exposure to value. Overall, the Fund’s alpha source (the investment approach that an active investment manager takes in an effort to generate excess returns relative to a benchmark) exposures delivered mixed results. Positions in low-volatility and value stocks detracted from performance in the first half of the reporting period, but exposure to low-volatility and value stocks in 2025 more than offset the underperformance in 2024.

Among the Fund’s sub-advisers, LSV Asset Management outperformed the benchmark Russell 3000 Index (USD) due to favorable stock selection among low-volatility stocks, as well as strong stock selection in the healthcare sector. During the portion of the reporting period in which Allspring Global Investments, LLC (“Allspring”) was a Fund sub-adviser, the manager’s performance modestly outperformed the benchmark due to its low-beta exposure, positions in value stocks, and strong stock selection in the healthcare and information technology sectors. During the brief period in which Acadian Asset Management LLC (“Acadian”) was a sub-adviser, the manager underperformed the benchmark.

How did the Fund perform in the last year?

The Fund outperformed its primary benchmark, the MSCI World Index (Net) (USD), for the 12-month period ending May 31, 2025. The Fund underperformed for the first half of the reporting period due to headwinds to low-volatility, value exposure, and an underweight allocation to the U.S. These trends reversed in 2025 due to heightened market volatility amid uncertainty around U.S. tariff policy and concerns around artificial intelligence (AI) capital expenditures. Fund performance benefited from this market rotation given its low-volatility bias, exposure to value, and underweight to the U.S. Overall, the Fund’s alpha source (the investment approach that an active investment manager takes in an effort to generate excess returns relative to a benchmark) exposures delivered mixed results for the reporting period as positions in low-volatility and value stocks detracted from performance in the first half of the reporting period, but exposure to low-volatility and value stocks in 2025 more than offset the underperformance in 2024.

Among the Fund’s sub-advisers, Acadian Asset Management LLC outperformed the benchmark MSCI World Index due to favorable stock selection in the consumer staples, healthcare, and information technology sectors, as well as strong selection among small and mega-cap stocks. LSV Asset Management outperformed the benchmark due to its exposure to value within the low-volatility segment of the market, along with favorable stock selection in the healthcare and consumer staples sectors. During the portion of the reporting period in which Allspring Global Investments (“Allspring”) was a Fund sub-adviser, the manager modestly outperformed the benchmark due to its low-beta exposure (beta is a quantitative measure of the volatility relative to a benchmark) and strong stock selection in the information technology, healthcare, and financials sectors.

How did the Fund perform in the last year?

The Fund outperformed its benchmark, the MSCI ACWI ex USA Index (NR) (USD)—which tracks the performance of both developed-market and emerging market countries, excluding the United States—for the 12-month period ending May 31, 2025.

Alpha source exposures (the investment approach that an active investment manager takes in an effort to generate excess returns relative to a benchmark) contributed positively to Fund performance, particularly value and momentum, as both factors performed well despite the broader underperformance of quality stocks.

Four out of the Fund’s five sub-advisers outperformed the benchmark MSCI ACWI ex USA Index (NR) (USD) for the reporting period. Lazard Asset Management LLC's (Lazard) 130/30 Momentum strategy benefited from a favorable momentum environment and effective short positioning. Notably, Lazard is the only Fund manager utilizing derivatives, which comprise approximately 50% of its 160% gross exposure. Acadian Asset Management LLC's outperformance was attributable to strong returns from value and momentum exposures. Pzena Investment Management, LLC, a deep value manager, outperformed due primarily to its allocation to European banks. Lazard’s International Quality Growth strategy also outperformed despite the headwinds faced by quality factors overall. Strong stock selection in the technology sector and in numerous equity markets globally contributed significantly to performance.

The performance of Brickwood Asset Management LLP (Brickwood), the Fund’s second value manager, lagged the benchmark over the reporting period, attributable to positions in the consumer discretionary and industrials sectors. Finally, Delaware Investments Fund Advisers, a series of Macquarie Investment Management Business Trust underperformed. As a quality manager with a low-volatility bias, both of its core factors lagged in the strong market environment consistent with our expectations. Stock selection, especially in consumer-focused apparel names, weighed further on performance.

How did the Fund perform in the last year?

The Fund underperformed its benchmark, the MSCI EFM (Emerging+Frontier Markets) Index (Net) (USD) ("MSCI EFM Index"), for the 12-month period ending May 31, 2025.

Large-cap stocks drove the benchmark MSCI EFM Index’s gains over the reporting period, led by a combination of enthusiasm over artificial intelligence (AI)-driven growth in shares of large-cap Chinese ecommerce and internet companies, expectations of government support, and continued strength in Taiwanese technology stocks from AI demand from U.S. technology companies. The Fund is underweight to these themes and areas of the market due to its structural allocation to frontier- and emerging-market small-cap stocks. Consequently, China was the biggest detractor from performance among countries given its underweight position in the Fund. Communication services and information technology were the biggest detractors among sectors for the period.

Regarding the Fund’s sub-advisers, JOHCM (USA) Inc. (“JOHCM”) weighed on performance as its momentum investment style (in which investors buy stocks that have shown recent price gains and sell stocks that have recently declined) faced headwinds over the reporting period from China’s resurgence and India’s underperformance. JOHCM’s focus on small-cap stocks also had a negative impact on Fund performance as large caps outperformed over the period. Causeway Capital Management LLC’s multifactor investment approach faced headwinds as momentum and quality both lagged the market over the period; this was not enough to offset the outperformance of the manager’s exposure to the value factor. WCM Investment Management, LLC was the largest contributor to Fund performance due to positive stock selection. RWC Asset Advisors (US) LLC performed well due to frontier markets’ outperformance versus emerging markets during the reporting period. Robeco Institutional Asset Management US Inc. (“Robeco”) also contributed positively to Fund performance over the period due to a tailwind to value stocks. Robeco posted strong results in the financials, real estate, and industrials sectors, especially Greek banks and United Arab Emirates real estate stocks.

How did the Fund perform in the last year?

The Fund outperformed its benchmark, the ICE BofA USD 3-Month Deposit Offered Rate Constant Maturity Index, which tracks the performance of a synthetic asset paying a deposit offered rate to the stated maturity—for the 12-month period ending May 31, 2025.

Fund performance for the reporting period was bolstered by holdings in spread sectors. An allocation to corporate bonds contributed to Fund performance as spreads in the front end of the yield curve remained relatively steady despite volatility during the first five months of 2025. The Fund’s positions in asset-backed securities (ABS) enhanced performance as various subsectors, such as franchises and student loans, performed well. Holdings in commercial mortgage-backed securities (CMBS) also contributed positively to Fund performance. Positions in non-Agency MBS contributed positively to performance as the sector remained supported by home- price appreciation and limited supply. An allocation to collateralized loan obligations (CLOs) also added to performance. The Fund’s holdings in bank loans performed well and were positive contributors during the reporting period as credit fundamentals remained on solid footing and risk assets outperformed the overall fixed-income market.

Regarding the Fund’s sub-advisers, Manulife Investment Management (US) LLC benefited from allocations to ABS, CMBS, and Non-Agency MBS. Wellington Management Company, LLP's strong performance for the period was attributable to an allocation to non-agency MBS, corporate bonds, and AAA CLOs. Ares Capital Management II, LLC's performance was enhanced by positioning in bank loans.

The Fund’s use of derivatives had no material impact on performance during the period.

How did the Fund perform in the last year?

The Fund modestly outperformed its benchmark, the Bloomberg U.S. Aggregate Bond Index (TR) (USD)—which tracks the performance of fixed-rate, publicly issued, non-investment-grade bonds—for the 12-month period ending May 31, 2025.

Fund performance for the reporting period benefited from holdings in spread sectors. Both an overweight position and security selection in agency mortgage-backed securities (MBS) contributed to Fund performance given the managers’ general preference for specified pools. Positioning within the corporate credit sector bolstered Fund performance due to security selection in the industrials sector. An overweight to asset-backed securities (ABS) added to Fund performance as the managers preferred prime tranches within auto loans and credit cards. Within commercial mortgage-backed securities (CMBS), allocations to higher-quality tranches and class-A properties contributed. The Fund’s slightly long duration posture had minimal impact on performance while a steepening yield curve position had a positive impact as the curve steepened over the period.

Regarding the Fund’s sub-advisers, Allspring Global Investments, LLC benefited from security selection in both corporate bonds and securitized assets. Jennison Associates LLC’s yield-curve positioning enhanced Fund performance as the curve steepened over the period. Metropolitan West Asset Management, LLC outperformed due to an overweight to agency MBS. The performance of MetLife Investment Management, LLC was bolstered by security selection within the corporate sector.

The Fund’s use of derivatives had no material impact on performance during the reporting period.

How did the Fund perform in the last year?

The Fund modestly outperformed its benchmark, the ICE BofA U.S. High Yield Constrained Index (USD), over the 12-month period ending May 31, 2025.

Positive contributors to Fund performance for the reporting period included an overweight position and security selection in the healthcare sector, security selection in telecommunications, and an underweight position and security selection in the leisure sector. Fund performance was hampered by security selection in the transportation, retail, and basic industry sectors.

Among the Fund’s sub-advisers, Ares Capital Management II, LLC outperformed the benchmark ICE BofA U.S. High Yield Constrained Index (USD) due to security selection in the healthcare sector, and both an underweight allocation to and security selection in retail. Benefit Street Partners, LLC's outperformance was attributable to security selection in financial services and technology and electronics. Brigade Capital Management, LP outperformed due to an overweight to and security selection in the healthcare and telecommunications sectors. J.P. Morgan Investment Management, Inc.'s outperformance resulted from an overweight position and security selection in media, and an underweight to and security selection in capital goods. T. Rowe Price Associates, Inc. lagged the benchmark due to an overweight to and security selection in energy, as well as security selection in retail. SEI Investment Management Corporation’s longstanding allocation to structured credit underperformed the broader high-yield market over the reporting period.

Regarding the use of derivatives during the reporting period, the Fund employed currency forwards for the Canadian dollar and the Australian dollar. These positions did not have an impact on Fund performance.

How did the Fund perform in the last year?

The Fund outperformed its benchmark, a 70%/30% blend of the Bloomberg U.S. Long Credit Index and the Bloomberg U.S. Long Government Index, for the 12-month period ending May 31, 2025.

The Federal Reserve (Fed) surprised the markets by reducing the federal-funds rate by 50 basis points at its September 2024 meeting. The central bank subsequently implemented additional 25-basis-point cuts following its meetings in November and December 2024. The Fed then paused its rate-cutting cycle through the end of the reporting period as it continues to evaluate the effects of trade and fiscal policy on the broader economy and financial markets. The implementation of tariffs during the first four months of 2025 caused spreads to widen materially before tightening back close to pre-tariff levels.

Fund performance for the reporting period was bolstered by holdings in corporate bonds, particularly in the industrials and financials sectors. This was partially offset by the negative impact of an underweight allocation to corporate bonds and an overweight to U.S. Treasurys, as the corporate sector outperformed over the period. An underweight position in BBB rated issues detracted from Fund performance as lower-quality securities outperformed during the reporting period.

Regarding the Fund’s sub-advisers, Legal & General Investment Management America, Inc. (LGIM) benefited from selection in the industrials sector, most notably in consumer non-cyclical and capital goods. Jennison Associates LLCs’ performance was enhanced by a yield-curve steepening position; this was partially offset by defensive credit positioning, while Metropolitan West Asset Management, LLC benefited from security selection in the financials sector. Income Research + Management (IRM) slightly outperformed the Fund's Blended Benchmark for the period due to security selection.

The Fund’s use of derivatives had no material impact on performance during the period.

How did the Fund perform in the last year?

The Fund outperformed its benchmark, the Bloomberg Long A+ U.S. Credit Index (USD)—which tracks the performance of highly rated corporate and international dollar-denominated bonds with a remaining maturity of 10 years or more—for the 12-month period ending May 31, 2025.

The Federal Reserve (Fed) surprised the markets by reducing the federal-funds rate by 50 basis points at its September 2024 meeting. The central bank subsequently implemented additional 25-basis-point cuts following its meetings in November and December 2024. The Fed then paused its rate-cutting cycle through the end of the reporting period as it continues to evaluate the effects of trade and fiscal policy on the broader economy and financial markets. Corporate spreads widened slightly over the reporting period. Volatility was muted through 2024; however, the implementation of tariffs during the first four months of 2025 caused spreads to widen materially before tightening back close to pre-tariff levels.

Fund performance for the reporting period was bolstered by holdings in corporate bonds, particularly in the industrials and financials sectors. An overweight allocation to financials partially detracted from Fund performance, as it was the worst performing long-term corporate subsector during the period. An allocation to BBB rated bonds, which are not represented in the benchmark Bloomberg Long A+ U.S. Credit Index (USD), contributed to Fund performance, as lower-quality issues outperformed higher-quality securities over the period. An allocation to U.S. Treasury detracted from Fund performance as the credit sector outperformed during the period.

Regarding the Fund’s sub-advisers, MetLife Investment Management, LLC's performance for the reporting period was enhanced by an allocation to BBB rated bonds. Both Income Research + Management (IRM) and Legal & General Investment Management America, Inc. benefited from security selection in the corporate sector, while Jennison Associates’ yield curve steepener contributed positively to Fund performance. Metropolitan West Asset Management, LLC's performance was bolstered by security selection in the financials sector, particularly banks.

The Fund’s use of derivatives had no material impact on performance during the period.

How did the Fund perform in the last year?

The Fund outperformed its benchmark, the Bloomberg Short U.S. Treasury 9-12 Month Index (USD), for the 12-month period ending May 31, 2025.

Fund performance for the reporting period benefited from an allocation to corporate bonds as spreads in the front end of the yield curve remained relatively steady despite volatility during the first five months of 2025. Allocations within asset-backed securities (ABS) benefited performance as the Fund’s managers generally preferred higher-quality prime tranches within credit cards and auto loans. Non-agency mortgage-backed securities (MBS) contributed positively to performance as the sector remained supported by home-price appreciation and limited supply. A small allocation to AAA rated collateralized loan obligations (CLOs) also added to performance.

Regarding the Fund’s sub-advisers, both MetLife Investment Management, LLC (“MetLife”) and Wellington Management Company, LLP (“Wellington”) outperformed the benchmark for the period. MetLife benefited from allocations to corporate bonds and prime credit cards and auto loans. Wellington’s outperformance was attributable to an allocation to non-agency MBS, corporate bonds, and AAA rated CLOs.

The Fund’s use of derivatives had no material impact on performance during the period.

How did the Fund perform in the last year?

The Fund outperformed its performance benchmark, a 50%/50% blend of the JPM EMBI Global Diversified Index and the JPM GBI-EM Global Diversified Index, for the 12-month period ending May 31, 2025.

Over the reporting period, in hard-currency emerging markets, high-yield bonds outperformed investment-grade securities. Local-currency markets also garnered positive returns due mainly to a rally in local rates. Emerging-market currencies recorded modestly positive returns during the period, as most currencies depreciated against the U.S. dollar.

Among the Fund’s sub-advisers, Marathon Asset Management (“Marathon”), Grantham Mayo van Otterloo ("GMO"), and Neuberger Berman Investment Advisers (“Neuberger”) (which was terminated in December 2024) added value through high-yield exposure, particularly to Argentina and Venezuela. Marathon also benefited from strong security selection and overweights to Peru and Mexico.

Local-currency sub-adviser Ninety One UK Ltd. (“Ninety One”) (terminated in December 2024) outperformed the Fund’s blended benchmark, bolstered by underweight allocations to South Africa and Mexico. This was partly offset by the negative impact of the exposure to Brazil. Colchester Global Investors underperformed as emerging-market currencies depreciated over the reporting period, most notably in the Latin America region, where the sub-adviser had an overweight position.

New local-currency managers Artisan Partners Limited Partnership (“Artisan”) and Invesco Advisers (“Invesco”), both of which were added as Fund sub-advisers in December 2024, saw gains from Brazilian and Mexican exposures, which performed well against the U.S. dollar during the period. However, Turkish rates and currency exposure detracted from performance, particularly for Invesco.

Regarding the use of derivatives over the reporting period, the Fund employed currency forwards and interest rate swaps to manage active currency and duration exposures. Currency forwards and interest rate swaps had a positive impact on Fund performance, with effects varying by country, depending on local-rate and currency moves.

How did the Fund perform in the last year?

The Fund performed in line with its benchmark, the Bloomberg 1-5 Year U.S. TIPS Index (USD), for the 12-month period ending May 31, 2025.

The Bloomberg 1-5 Year U.S. TIPS Index (USD) returned 6.97% over the reporting period, outperforming the comparable Bloomberg 1-5 Year U.S.Treasury Index (USD), which returned 6.07%. The outperformance of the the Bloomberg 1-5 Year U.S. TIPS Index (USD) was driven primarily by a significant decline in short-dated real U.S. Treasury yields (yields after adjusting for inflation). The 2-year real yield fell 134 basis points (bps) over the reporting period and the 5-year real yield declined by 59 bps, providing strong price support to inflation-linked securities. In contrast, longer-dated real U.S. Treasury yields rose modestly, leading to a steepening of the real yield curve (in which the spread between short- and long-term yields increases).

The breakeven inflation rate (the difference between the nominal yield on a fixed-rate bond and the real yield on an inflation-linked bond) widened slightly at the front end of the U.S. Treasury yield curve during the reporting period, with 2-year breakevens rising by 35 bps, suggesting modest repricing of near-term inflation expectations. The 5-year breakeven yield curve was little changed, and longer-dated breakevens were broadly stable to slightly narrower. Overall, the inflation risk premium was largely unchanged, reinforcing the idea that performance was dominated by real yield compression (a decrease in the real yield of a bond) rather than breakeven expansion.

How did the Fund perform in the last year?

The Fund outperformed its benchmark, the ICE BofA 1-3 Year U.S. Treasury Index (USD)—which tracks the performance of the direct sovereign debt of the U. S. government with a maturity of at least one year and less than three years—for the 12-month period ending May 31, 2025.

Fund performance for the reporting period benefited from holdings in spread sectors. An allocation to corporate bonds contributed to Fund performance as spreads in the front end of the yield curve remained relatively steady despite volatility during the first five months of 2025. Allocations to asset-backed securities (ABS) also contributed positively to performance. Despite interest-rate volatility, agency mortgage-backed securities (MBS) performed well during the reporting period. Consequently, the Fund’s positioning and security selection in the sector bolstered performance. Additionally, positions in commercial mortgage-backed securities (CMBS), enhanced Fund performance, with the managers preferring senior tranches. A small allocation to AAA rated collateralized loan obligations (CLOs) also had a positive impact on performance.

Regarding the Fund’s sub-advisers, both MetLife Investment Management, LLC (“MetLife”) and Metropolitan West Asset Management, LLC (“MetWest”) outperformed the benchmark ICE BofA 1-3 Year U.S. Treasury Index (USD) for the reporting period. MetLife benefitted from allocations to corporate bonds and prime credit cards and auto loans. MetWest’s outperformance was attributable to allocations to agency MBS and corporate bonds.

The Fund’s use of derivatives had no material impact on performance during the reporting period.

How did the Fund perform in the last year?

The Fund modestly outperformed its benchmark, the Bloomberg A+ U.S. Credit Index (USD)—which tracks the performance of fixed-income securities with one of the three highest credit ratings—for the 12-month period ending May 31, 2025.

The Federal Reserve (Fed) surprised the markets by reducing the federal-funds rate by 50 basis points at its September 2024 meeting. The central bank subsequently implemented additional 25-basis-point cuts following its meetings in November and December 2024. The Fed then paused its rate-cutting cycle through the end of the reporting period as it continues to evaluate the effects of trade and fiscal policy on the broader economy and financial markets. Corporate spreads widened slightly over the reporting period. Volatility was muted through 2024; however, the implementation of tariffs during the first four months of 2025 caused spreads to widen materially before tightening back close to pre-tariff levels.

Fund performance for the period was enhanced by holdings in corporate bonds, particularly in the industrials and financials sectors, as well as an overweight allocation to the financials sector. An allocation to BBB rated securities contributed to Fund performance as lower-quality issues outperformed higher-quality securities over the reporting period. The Fund’s position in U.S. Treasurys, which are not represented in the benchmark Bloomberg A+ U.S. Credit Index (USD), detracted from performance.

Among the Fund’s sub-advisers, MetLife Investment Management, LLC benefited from an allocation to BBB rated credits. The performance of both Income Research + Management (IRM) and Legal & General Investment Management America, Inc. (LGIM) was bolstered by corporate credit selection in financial and utility sectors.

The Fund’s use of derivatives had no material impact on performance for the reporting period.

How did the Fund perform in the last year?

The Fund outperformed its benchmark, the broad-market S&P 500 Index (TR)—a market-weighted index that tracks the performance of the 500 largest publicly traded U.S. companies and is considered representative of the broad U.S. stock market—for the 12-month period ending May 31, 2025.

Interest rate positions were the largest contributors to the Fund’s outperformance relative to the benchmark for the reporting period, attributable mainly to two yield curve steepeners. Yield curve steepeners benefit when the yield spread between short- and long-maturity U.S. Treasury securities increases. During the period, short-term yields were relatively anchored, while longer-term Treasury yields moved higher. The Fund held two U.S. consumer-price index (CPI) swaps, which in aggregate contributed positively to relative performance as inflation expectations rose over the reporting period. Two short-term U.S. interest rate positions based on the one-year Treasury note yield also enhanced Fund performance. These positions benefitted from market expectations for Federal Reserve interest rate cuts were tempered (the central bank implemented fewer rate cuts than previously expected).

The Fund’s currency positions largely detracted from relative performance over the reporting period. A euro versus U.S. dollar put option, a euro versus Japanese yen put option, and a Chinese yuan put option all weighed on Fund performance over the period. A position in broad commodities had a modestly positive impact as performance was mixed across commodities markets. Weakness in economically sensitive sectors such as energy and industrial metals was largely offset by strength in the precious metals sectors.

How did the Fund perform in the last year?

The Fund underperformed its benchmark, the Bloomberg 1-5 Year U.S. TIPS Index (USD), for the 12-month period ending May 31, 2025.

The majority of the Fund's underperformance relative to its benchmark for the reporting period was attributable to its commodities exposure, which saw mixed performance. The Fund’s equity long/short strategy detracted from performance as inflation moderated, with less inflation-sensitive sectors generally outperforming those with greater inflation-sensitivity. At the sector level, the Fund’s short exposure to consumer discretionary challenged performance as the job market remained robust and consumers continued to spend on non-essential goods and services. Holdings in the energy sector detracted from Fund performance due to pressured crude oil prices. The Fund's TIPS plus (Treasury Inflation-Protected Securities) allocation contributed positively to performance, benefiting from its credit exposure.

Among the Fund’s sub-advisers, Columbia Management Investment Advisers and UBS Asset Management underperformed the benchmark due to mixed performance for commodities. Equity long/short manager Franklin Advisers, Inc. also underperformed the benchmark as less inflation-sensitive sectors outperformed. Conversely, AllianceBernstein L.P benefited from its overweight credit exposure amid tighter credit spreads, especially in below-investment-grade bonds.

Regarding the use of derivatives during the reporting period, the Fund employed equity-index futures to hedge broad equity-market exposure; equity-index sector futures to obtain strategic exposure to equity-index sectors; bond futures and interest-rate swaps to hedge duration; credit default swaps (CDS) to hedge credit risk; and commodity futures to obtain diversified strategic exposure to commodities. The Fund’s allocation to commodity futures and exposure to equity-index sector futures contributed to performance. The exposures obtained through interest-rate swaps, CDS, equity-index futures, and bond futures detracted from Fund performance for the period, but provided the intended hedging.

Notes:

(1)

Audit fees include amounts related to the audit of the Registrant’s annual financial statements and services normally provided by the accountant in connection with statutory and regulatory filings.

(2)

See Item 4(g) for a description of the services comprising the fees disclosed in this category.

(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. In any instance where services require pre-approval, the Audit Committee will consider whether such services are consistent with SEC’s rules on auditor independence and whether the provision of such services would compromise the auditor’s independence.

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.

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 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. The Audit Committee will annually review and pre-approve the services that may be provided by the independent auditor during the following twelve months without obtaining specific pre-approval from the Audit Committee.

The Audit Committee will be informed by the CFO on a quarterly basis of all services rendered by the independent auditor.

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 (or the manner of their determination) 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 Year 2025	Fiscal Year 2024
Audit-Related Fees	0%	0%
Tax Fees	0%	0%
All Other Fees	0%	0%

(f) Not Applicable.

(g) The aggregate non-audit fees and services billed by KPMG for the fiscal years 2025 and 2024 were $360,799 and $363,759, respectively. Non-audit fees consist of SSAE No. 16 review of fund accounting and administration operations and an attestation report in accordance with Rule 17Ad-13.

(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.

(i) Not Applicable.

(j) Not Applicable.

Item 5. Audit Committee of Listed Registrants.

Not applicable.

Item 6. Schedule of Investments.

(a) The Schedules of Investments and Consolidated Schedules of Investments are included as part of the Financial Statements and Financial Highlights filed under Item 7 of this form.

NOTES TO FINANCIAL STATEMENTS / NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

May 31, 2025

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 26 registered funds: Large Cap, Large Cap Disciplined Equity, Large Cap Index, S&P 500 Index, Extended Market Index, Small Cap, Small Cap II, Small/Mid Cap Equity, U.S. Equity Factor Allocation, U.S. Managed Volatility, Global Managed Volatility, World Equity Ex-US, Screened World Equity Ex-US, Emerging Markets Equity, Opportunistic Income, Core Fixed Income, High Yield Bond, Long Duration, Long Duration Credit, Ultra Short Duration Bond, Emerging Markets Debt, Real Return, Limited Duration Bond, Intermediate Duration Credit, Dynamic Asset Allocation and Multi-Asset Real Return (each a “Fund,” collectively, the “Funds”) each of which are diversified Funds with the exception of the Emerging Markets Debt and Multi-Asset Real Return Funds. 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 goals, principal strategies and risks.

The DAA Commodity Strategy Subsidiary, Ltd. and the MARR Commodity Strategy Subsidiary, Ltd. (the “Subsidiaries”) are wholly-owned subsidiaries of the Dynamic Asset Allocation and Multi-Asset Real Return Funds, respectively. The Subsidiaries are organized under the laws of the Cayman Islands as an exempt limited company. Information regarding the Dynamic Asset Allocation and Multi-Asset Real Return Funds and their respective subsidiary has been consolidated on the Consolidated Schedule of Investments, Consolidated Statements of Assets and Liabilities, Consolidated Statements of Operations, Consolidated Statements of Changes in Net Assets and Consolidated Financial Highlights.

2. SIGNIFICANT ACCOUNTING POLICIES

The following are significant accounting policies, which are consistently followed in the preparation of its financial statements by the Funds. The Funds are investment companies that apply the accounting and reporting guidance issued in Topic 946 by the U.S. Financial Accounting Standards Board (“FASB”).

Use of Estimates — The preparation of financial statements, in conformity with U.S. 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 — Pursuant to the requirements of the 1940 Act and Rule 2a-5, the administrator, as delegated by the Board of Trustees (the “Board”), has the responsibility for the valuation of Fund investments with readily available market quotations in accordance with the Funds’ Valuation and Pricing Policy. The Trust's Board of Trustees has designated SEI Investments Management Corporation (“SIMC”) as the Valuation Designee for the Funds pursuant to Rule 2a-5 (the “Rule”) under the 1940 Act. The Valuation Designee has the responsibility for the fair value determination with respect to all Fund investments that do not have readily available market quotations or quotations that are no longer reliable. SIMC, in furtherance of the Board’s designation, has appointed a committee of SIMC persons to function as the Valuation Designee (the “Committee”) and has established a Valuation and Pricing Policy to implement the Rule and the Funds’ Valuation and Pricing Policy (together the “Policy”). When valuing portfolio securities, a Fund values securities listed on a securities exchange, market or automated quotation system for which quotations are readily available (other than securities traded on National Association of Securities Dealers Automated Quotations (“NASDAQ”) or as otherwise noted below) are valued at the last quoted sale price on an exchange or market (foreign or domestic) on which the securities are traded, or, if there is no such reported sale, at the most recent quoted bid price. The Funds value securities traded on NASDAQ at the NASDAQ official closing price. If available, debt securities, swaps (which are not centrally cleared), bank loans or debt tranches of collateralized debt obligations (including collateralized loan obligations), such as those held by the Funds, are priced based upon valuations provided by independent, third-party pricing agents. Such values generally reflect the last reported sales price if the security is actively traded. The third-party pricing agents may also value debt securities at an evaluated bid price by employing methodologies that utilize actual market transactions, broker-supplied valuations or other methodologies designed to identify the market value for such securities. Redeemable securities issued by open-end investment companies are valued at the investment company’s applicable net asset value, with the exception of ETFs, which are priced as equity securities. These open-end investment companies’ shares are offered in separate prospectuses, each of which describes the process by which the applicable investment company’s net asset value is determined. The prices of foreign securities are reported in local currency and converted to U.S. dollars

using currency exchange rates. If a security’s price cannot be obtained, as noted above, or in the case of an equity tranche of a collateralized debt obligations/collateralized loan obligations, the Funds will value the securities using a bid price from at least one independent broker.

On the first day a new debt security purchase is recorded, if a price is not available from a third-party pricing agent or an independent broker, the security may be valued at its purchase price. Each day thereafter, the debt security will be valued according to the Policy until a price from an independent source can be secured. Securities held by a Fund with remaining maturities of 60 days or less may be valued by the amortized cost method, which involves valuing a security at its cost on the date of purchase and thereafter (absent unusual circumstances) assuming a constant amortization to maturity of any discount or premium, regardless of the impact of fluctuations in general market rates of interest on the value of the instrument. While this method provides certainty in valuation, it may result in periods during which value, as determined by this method, is higher or lower than the price a Fund would receive if it sold the instrument. Further, the value of securities in the Fund can be expected to vary inversely with changes in prevailing interest rates. Should existing credit, liquidity or interest rate conditions in the relevant markets and issuer-specific circumstances suggest that amortized cost does not approximate fair value, then the amortized cost method may not be used.

Options and warrants are valued at the last quoted sales price. If there is no such reported sale on the valuation date, long positions are valued at the most recent bid price, and short positions are valued at the most recent ask price.

Futures and swaps cleared through a central clearing house (“centrally cleared swaps”) are valued at the settlement price established each day by the board of exchange on which they are traded. The daily settlement prices for financial futures and centrally cleared swaps are provided by an independent source. On days when there is excessive volume, market volatility or the future or centrally cleared swap does not end trading by the time a Fund calculates its Net Asset Value (“NAV”), the settlement price may not be available at the time at which the Fund calculates its NAV. On such days, the best available price (which is typically the last sales price) may be used to value a Fund’s futures or centrally cleared swaps position.

Foreign currency forward contracts are valued at the current day’s interpolated foreign exchange rate, as calculated using the current day’s spot rate, and the thirty, sixty, ninety and one-hundred eighty day forward rates provided by an independent source.

Prices for most securities held by a Fund are provided daily by third-party independent pricing agents. SIMC or a Sub-Adviser (“Sub-Adviser”), as applicable, reasonably believes that prices provided by independent pricing agents are reliable. However, there can be no assurance that such pricing service’s prices will be reliable. SIMC will continuously monitor the reliability of prices obtained from any pricing service and shall promptly notify the Funds’ administrator if it believes that a particular pricing service is no longer a reliable source of prices. The Funds’ administrator, in turn, will notify the Committee if it receives such notification from a Sub-Adviser, as applicable, or if the Funds’ administrator reasonably believes that a particular pricing service is no longer a reliable source for prices.

The Policy provides that any change in a primary pricing agent or a pricing methodology requires prior approval by the Board. However, when the change would not materially affect valuation of a Fund’s net assets or involve a material departure in pricing methodology from that of a Fund’s existing pricing agent or pricing methodology, ratification may be obtained at the next regularly scheduled meeting of the Board.

Securities for which market prices are not readily available, for which market prices are determined to be unreliable, or which cannot be valued using the methodologies described above are valued in accordance with Rule 2a-5 and the Policy.

The Valuation Designee must monitor for circumstances that may necessitate that a security be valued using Fair Value Procedures which can include: (i) the security's trading has been halted or suspended, (ii) the security has been de-listed from a national exchange, (iii) the security's primary trading market is temporarily closed at a time when under normal conditions it would be open, (iv) the security has not been traded for an extended period of time, (v) the security's primary pricing source is not able or willing to provide a price, (vi) trading of the security is subject to local government-imposed restrictions; or (vii) a significant event (as defined below). When a security is valued in accordance with the Policy, the Committee will determine the value after taking into consideration relevant information reasonably available to the Committee. Examples of factors the Committee may consider include: (i) the type of security or asset, (ii) the last trade price, (iii) evaluation of the forces that influence the market in which the security is purchased and sold, (iv) the liquidity of the security, (v) the size of the holding in a Fund or (vi) any other appropriate information.

396

SEI Institutional Investments Trust

The Committee is responsible for selecting and applying, in a consistent manner, the appropriate methodologies for determining and calculating the fair value of holdings of the Funds, including specifying the key inputs and assumptions specific to each asset class or holding.

The determination of a security’s fair value price often involves the consideration of a number of subjective factors, and is therefore subject to the unavoidable risk that the value assigned to a security may be higher or lower than the security’s value would be if a reliable market quotation for the security was readily available.

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 NAV. The closing prices of such securities may no longer reflect their market value at the time a Fund calculates NAV if an event that could materially affect the value of those securities (a “Significant Event”), including substantial fluctuations in domestic or foreign markets or occurrences not tied directly to the securities markets, such as natural disasters, armed conflicts or significant governmental actions, has occurred between the time of the security’s last close and the time that a Fund calculates NAV. A Fund may invest in securities that are primarily listed on foreign exchanges that trade on weekends or other days when a Fund does not price its shares. As a result, the NAV of a Fund’s shares may change on days when shareholders will not be able to purchase or redeem Fund shares.

A Significant Event may relate to a single issuer or to an entire market sector. If SIMC or a Sub-Adviser becomes aware of a Significant Event that has occurred with respect to a security or group of securities after the closing of the exchange or market on which the security or securities principally trade, but before the time at which the Funds calculate NAV, it may request that a Committee meeting be called. In addition, the Funds use several processes, with respect to certain securities to monitor the pricing data supplied by various sources, including price comparisons and price movements. Any identified discrepancies are researched and subject to the procedures described above.

All of the Funds which hold international securities use a third-party fair valuation vendor. The vendor provides a fair value for foreign securities held by the Funds based on certain factors and methodologies (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 will value the non-U.S. securities in their portfolios that exceed the applicable “confidence interval” based upon the adjusted prices provided by the fair valuation vendor.

In accordance with U.S. GAAP, fair value is defined as the price that a Fund would receive upon selling an investment in an orderly 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.) or quoted prices for identical instruments in inactive markets; and

Level 3 — significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments).

Investments are classified within the level of the lowest significant input considered in determining fair value. Investments classified within Level 3 whose fair value measurement considers several inputs may include Level 1 or Level 2 inputs as components of the overall fair value measurement.

Debt securities are valued in accordance with the evaluated bid price supplied by the pricing service and generally categorized as Level 2 in the hierarchy. Other securities that are categorized as Level 2 in the hierarchy include, but are not limited to, preferred stocks, bank loans, warrants, swaps and forward contracts. The Fund may use a systematic

fair valuation model provided by an independent pricing service to value foreign equity securities in order to adjust for stale pricing, which may occur between the close of certain foreign exchanges and the New York Stock Exchange. These are generally categorized as Level 2 in the hierarchy.

When independent prices are unavailable or unreliable, debt securities and swaps may be valued utilizing pricing matrices which consider similar factors that would be used by independent pricing services. These are generally categorized as Level 2 in the hierarchy but may be Level 3 depending on the circumstances. For certain collateralized debt obligations, corporate obligations, mortgage backed securities, auction rate preferred securities and loan participations where observable inputs are limited, assumptions about market activity and risk are used and are categorized as Level 3 in the hierarchy.

The valuation techniques used by the Funds to measure fair value during the year ended May 31, 2025 maximized the use of observable inputs and minimized the use of unobservable inputs. For details of the investment classification, reference the Schedules of Investments.

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

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

Amortization and accretion is calculated using the scientific interest method, which approximates the effective interest method over the holding period of the security. Amortization of premiums and discounts is included in interest income. Consent fees and amendment income received from Bank Loans is recorded as interest income in the accompanying Statements of Operations/Consolidated Statements of Operations.

For Treasury Inflation-Protected Securities, the principal amount is adjusted daily to keep pace with inflation.

Interest is accrued based on the adjusted principal amount. The adjustments to principal due to inflation are reflected as increases or decreases to interest in the accompanying Statements of Operations/Consolidated Statements of Operations. Such adjustments may have a significant impact on a Fund’s distributions.

Cash and Cash Equivalents — Idle cash and currency balances may be swept into various overnight sweep accounts and are classified as cash and cash equivalents on the Statements of Assets and Liabilities/Consolidated Statements of Assets and Liabilities and Consolidated Statements of Cash Flows. These amounts, at times, may exceed United States federally insured limits. Amounts swept are available on the next business day.

Cash Equivalents, as shown on the Schedule of Investments/Consolidated Schedule of Investments, are classified as Investments on the Statements of Assets and Liabilities/Consolidated Statements of Assets and Liabilities.

Repurchase Agreements — Securities pledged as collateral for repurchase agreements are held by each Fund’s custodian bank until the repurchase date of the repurchase agreement. The Funds may also invest in tri-party repurchase agreements. Securities held as collateral for tri-party repurchase agreements are maintained by the broker’s custodian bank in a segregated account until the repurchase date of the repurchase agreement. Provisions of the repurchase agreements and the Trust’s policies require that the market value of the collateral, including accrued interest thereon, is sufficient in the event of default by the counterparty. If the counterparty defaults and the value of the collateral declines, or if the counterparty enters into an insolvency proceeding, realization of the collateral by the Funds may be delayed or limited. Refer to each Fund’s Schedule of Investments or Consolidated Schedule of Investments for details regarding open repurchase agreements as of May 31, 2025, if applicable.

Reverse Repurchase Agreements — To the extent consistent with its Investment Objective and Strategies, a Fund may enter into 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. Assets are then segregated to cover the requirements to repurchase the assets. 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

398

SEI Institutional Investments Trust

becomes insolvent, a Fund’s 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. Refer to each Fund’s Schedule of Investments or Consolidated Schedule of Investments for details regarding open reverse repurchase agreements as of May 31, 2025, if applicable.

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.

Commodity-Linked Investments — To the extent consistent with its Investment Objective and Strategies, the Dynamic Asset Allocation and Multi-Asset Real Return Funds may invest in commodity investments to provide exposure to the investment returns of the commodities markets. Commodity investments include notes with interest payments that are tied to an underlying commodity or commodity index, ETFs or other exchange-traded products that are tied to the performance of a commodity or commodity index or other types of commodities or commodity indices. The Dynamic Asset Allocation and Multi-Asset Real Return Funds may also invest in equity securities of issuers in commodity-related industries.

The Dynamic Asset Allocation and Multi-Asset Real Return Funds may also seek to gain exposure to the commodity markets, in whole or in part, through investments in a wholly owned Subsidiary. The Subsidiary, unlike the Fund, may invest to a significant extent directly in commodities and in equity-linked securities and commodity-linked derivative instruments, including options, futures contracts, swaps, options on futures contracts and commodity-linked structured notes. The Subsidiary may also invest in other instruments in which the Fund is permitted to invest, either as investments or to serve as margin or collateral for its derivative positions. A Fund may invest up to 25% of its total assets in its Subsidiary.

In order for a Fund to qualify as a regulated investment company under Subchapter M of the Code, the Fund must derive at least 90% of its gross income each taxable year from qualifying income. The status of certain commodity-linked derivative instruments as qualifying income has been addressed in Revenue Ruling 2006-1 and Revenue Ruling 2006-31 which provide that income from certain commodity-linked derivative instruments in which the Fund invests will not be considered qualifying income. To the extent the Dynamic Asset Allocation and Multi-Asset Real Return Funds invest in such instruments directly, each Fund will seek to restrict its income from commodity-linked

derivative instruments that do not generate qualifying income, such as commodity-linked swaps, to a maximum of 10% of its gross income (when combined with its other investments that produce non-qualifying income).

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

(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 that is due to changes in the foreign exchange rates from that which is due to changes in market prices of investments.

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. A Fund may also engage in currency transactions to enhance that Fund’s returns. All commitments are marked-to-market daily at the applicable foreign exchange rate, and any resulting unrealized gains or losses are recorded currently. A 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 Statements of Assets and Liabilities or Consolidated Statements of Assets and Liabilities. Refer to each Fund’s Schedule of Investments or Consolidated Schedule of Investments for details regarding open forward foreign currency contracts as of May 31, 2025, if applicable.

Futures Contracts — To the extent consistent with its Investment Objective and Strategies, a Fund may use futures contracts for tactical hedging purposes as well as

SEI Institutional Investments Trust

NOTES TO FINANCIAL STATEMENTS / NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

May 31, 2025

to enhance the Fund’s returns. In addition, fixed income funds will utilize futures contracts to help manage duration and yield curve exposure. These Funds’ investments in futures contracts are designed to enable the Funds to more closely approximate the performance of their benchmark indices. 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 contracts are 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, futures contracts involve 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 Statements of Assets and Liabilities or Consolidated Statements of Assets and Liabilities. Refer to each Fund’s Schedule of Investments or Consolidated Schedule of Investments for details regarding open futures contracts as of May 31, 2025, if applicable.

Master Limited Partnerships — Investments in units of master limited partnerships (“MLPs”) involve risks that differ from an investment in common stock. Holders of the units of master limited partnerships have more limited control and limited rights to vote on matters affecting the partnership. There are also certain tax risks associated with an investment in units of master limited partnerships. In addition, conflicts of interest may exist between common unit holders, subordinated unit holders and the general partner of a master limited partnership, including a conflict arising as a result of incentive distribution payments. The benefit a Fund derives from investment in MLP units is largely dependent on the MLPs being treated as partnerships and not as corporations for federal income tax purposes. If an MLP were classified as a corporation for federal income tax purposes, there would be reduction in the after-tax return to a Fund of distributions from the MLP, likely causing a reduction in the value of a Fund's shares. MLP entities are typically focused in the energy, natural resources and real estate sectors of the economy. A downturn in the energy, natural resources or real estate

sectors of the economy could have an adverse impact on a Fund. At times, the performance of securities of companies in the energy, natural resources and real estate sectors of the economy may lag the performance of other sectors or the broader market as a whole. Refer to each Fund’s Schedule of Investments or Consolidated Schedule of Investments for details regarding Master Limited Partnerships, if applicable.

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 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 on written options could exceed amounts disclosed on the Statements of Assets and Liabilities. Refer to each Fund’s Schedule of Investments or Consolidated Schedule of Investments for details regarding open option/swaption contracts as of May 31, 2025, if applicable.

Securities Sold Short—To the extent consistent with its Investment Objective and Strategies, 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. A 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.

A Fund must comply with Rule 18f-4 under the 1940 Act with respect to its short sale borrowings, which are considered Derivative Transactions under the Rule. Refer to each Fund’s Schedule of Investments or Consolidated Schedule of Investments for details regarding securities sold short as of May 31, 2025, if applicable.

Swap Agreements — To the extent consistent with its Investment Objective and Strategies, a Fund may invest in swap contracts as an efficient means to synthetically obtain exposure to securities or baskets of securities and to manage a Fund’s interest rate duration and yield curve exposure. Swap contracts may also be used to mitigate a Fund’s overall level of risk and/or a Fund’s risk to particular types of securities, currencies or market segments. Interest rate swaps may further be used to manage a Fund’s yield spread sensitivity. A Fund may buy swaps in an attempt to manage credit risk where a Fund has credit exposure to an issuer, and a Fund may sell credit default swaps to more efficiently gain credit exposure to a security or basket of securities. 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. Swap agreements are privately negotiated in the over-the-counter market (“OTC swaps”) or may be executed in a multilateral or other trade facility platform, such as a registered commodities exchange (“Centrally Cleared swaps”). Interest rate swaps involve the exchange by a Fund with another party of their respective commitments to pay or receive interest

(e.g., an exchange of floating rate payments for fixed rate payments) with respect to a notional amount of principal. Credit-default swaps involve periodic payments by a Fund or counterparty based on a specified rate multiplied by a notional amount assigned to an underlying debt instrument or group of debt instruments in exchange for the assumption of credit risk on the same instruments. In the event of a credit event, usually in the form of a credit rating downgrade, the party receiving periodic payments (i.e. floating rate payer) must pay the other party (i.e. fixed rate payer) an amount equal to the recovery rate used to settle the contracts. The recovery rate is a function of how many credit default swap investors wish to deliver the security or receive the security. The recovery rate is determined through an auction process. 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 SOFR or some other form of indices on the notional amount. Interest rate swaps involve the exchange by a Fund with another party of their respective commitments to pay or receive interest (e.g., an exchange of floating rate payments for fixed rate payments) with respect to a notional amount of principal to manage a Fund’s exposure to interest rates. Payments received or made are recorded as realized gains or loss. 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 Statements of Assets and Liabilities or Consolidated Statements of Assets and Liabilities. Interest rate swap contracts outstanding at period end, if any, are listed after a Fund’s portfolio. In connection with swap agreements securities may be set aside as collateral by a Fund’s custodian.

Swaps are marked-to-market daily based upon quotations from market makers and the resulting changes in market values, if any, are recorded as an unrealized gain or loss on the Statements of Operations or Consolidated Statements of Operations. Net payments of interest are recorded as realized gains or losses. Daily changes in valuation of Centrally Cleared swaps, if any, are recorded as a receivable or payable for the change in value as appropriate (“variation margin”) on the Statements of Assets and Liabilities or Consolidated Statements of Assets and Liabilities.

May 31, 2025

Entering into swap agreements involves, to varying degrees, elements of credit and market risk in excess of the amounts recognized on the Statements of Assets and Liabilities or Consolidated Statements 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. Refer to each Fund’s Schedule of Investments or Consolidated Schedule of Investments for details regarding open swap agreements as of May 31, 2025, if applicable.

Forward Treasury Commitments — To the extent consistent with its Investment Objective and Strategies, 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 the Fund to purchase or sell securities for a predetermined price or yield, with payment and delivery taking place beyond the customary settlement period. When purchasing a security on a delayed delivery basis, the Fund assumes the rights and risks of ownership of the security, including the risk of price and yield fluctuations, and takes such fluctuations into account when determining its net asset value. The 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 the Fund has sold a security on a delayed delivery basis, the Fund does not participate in future gains and losses with respect to the security.

A Fund must comply with Rule 18f-4 under the 1940 Act with respect to its delayed delivery transactions, which are considered Derivative Transactions under the Rule. Refer to each Fund’s Schedule of Investments or Consolidated Schedule of Investments for details regarding delayed delivery transactions as of May 31, 2025, if applicable.

Participation Notes (P-Notes) — To the extent consistent with its Investment Objective and Strategies, a Fund may acquire P-Notes issued by participating banks or broker-dealers. P-Notes are participation interest notes that are designed to offer a return linked to a particular underlying equity, debt, currency or market. The P-Notes in which the Fund may invest will typically have a maturity of one year. When purchasing a P-Note, the posting of margin is not required because the full cost of the P-Note (plus commission) is paid at the time of purchase. When the P-Note matures, the issuer will pay to, or receive from, the purchaser the difference between the minimal value of the underlying instrument at the time of purchase and that instrument’s value at maturity. Investments in P-Notes involve the same risks associated with a direct investment in the underlying foreign companies of foreign securities markets that they seek to replicate.

In addition, there can be no assurance that the trading price of P-Notes will equal the underlying value of the foreign companies or foreign securities markets that they seek to replicate. The holder of a participation note that is linked to a particular underlying security is entitled to receive any dividends paid in connection with an underlying security or instrument. However, the holder of a participation note does not receive voting rights as it would if it directly owned the underlying security or instrument. P-Notes are generally traded over-the-counter. P-Notes constitute general unsecured contractual obligations of the banks or broker-dealers that issue them and the counterparty. There is also counterparty risk associated with these investments because the Fund is relying on the creditworthiness of such counterparty and has no rights under a participation note against the issuer of the underlying security. In addition, the Fund will incur transaction costs as a result of investments in P-Notes.

Loan Participations and Brady Bonds — To the extent consistent with its Investment Objective and Strategies, a Fund may invest in Loan Participations. Loan Participations include fixed and floating rate loans that are privately negotiated between a corporate borrower and one or more financial institutions, including, but not limited to, term loans, revolvers, and other instruments issued in the bank loan market. Each Fund may acquire interests in loans directly (by way of assignment from the selling institution) or indirectly (by way of the purchase of a participation interest from the selling institution). Under a bank loan assignment, a Fund generally will succeed to all the rights and obligations of an assigning lending institution and becomes a lender under the loan agreement with the relevant borrower in connection with that loan. Under bank loan participation, the Fund generally will have a contractual relationship only with the lender, not with the relevant borrower. As a result, a Fund generally will have the right to receive payments of principal, interest, and any fees to which it is entitled only from the lender selling the participation and only upon receipt by the lender of the payments from the relevant borrower. The Fund may not directly benefit from the collateral supporting the debt obligation in which it has purchased the participation. As a result, a Fund will assume the credit risk of both the borrower and the institution selling the participation to the Fund as of May 31, 2025. The interest rate indicated in the Fund’s Schedule of Investments is the rate in effect at May 31, 2025. Pursuant to the terms of certain loan agreements, the Funds may hold unfunded commitments in loan participations which are disclosed on the Statement of Assets and Liabilities. Unfunded commitments represent the remaining obligation of the Fund to the borrower. At any point in time, up to the maturity date of the issue, the borrower may demand the unfunded portion. Unfunded amounts, if any, are marked to market and any unrealized gains or losses are recorded in the Statement of Assets and Liabilities. The Funds disclose consent fees and amendment income in the Statement of Operations as “Interest income”.

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 — To the extent consistent with its Investment Objective and Strategies, 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 securities. A CLO is a trust typically collateralized by a pool of loans, which may include, among others, domestic and foreign senior secured loans, senior unsecured loans, and subordinate corporate loans, including loans that may be rated below investment grade or equivalent unrated loans. CDOs and CLOs may charge management fees and administrative expenses.

Dividends and Distributions to Shareholders — Dividends from net investment income are declared and paid to shareholders quarterly for the Large Cap, Large Cap Disciplined Equity, Large Cap Index, S&P 500 Index, Extended Market Index, Small Cap, Small Cap II, Small/Mid Cap Equity, U.S. Equity Factor Allocation, U.S. Managed Volatility, Opportunistic Income, Emerging Markets Debt and Real Return Funds; declared daily and paid monthly for the Core Fixed Income, High Yield Bond, Long Duration, Long Duration Credit, Ultra Short Duration Bond and Intermediate Duration Credit Funds; declared and paid at least annually for the Global Managed Volatility, World Equity Ex-US, Screened World Equity Ex-US, Emerging Markets Equity, Limited Duration Bond, Dynamic Asset Allocation and Multi-Asset 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.

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. For US REITs, 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.

Restricted Securities — The Funds may invest in private placement investments that were purchased through private offerings or acquired through initial public offerings and cannot be sold without prior registration under the Securities Act of 1933 or pursuant to an exemption therefrom. In addition, the Funds have generally agreed to further restrictions on the disposition of certain holdings as set forth in various agreements entered into in connection with the purchase of these investments. These investments are valued at fair value as determined in accordance with

SEI Institutional Investments Trust

403

NOTES TO FINANCIAL STATEMENTS / NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

May 31, 2025

the procedures approved by the Board. Please refer to the Schedule of Investments for Funds that held Restricted Securities.

Investment in Subsidiary — The Dynamic Asset Allocation and Multi-Asset Real Return Funds may invest in their own Subsidiary. By investing in its Subsidiary, each Fund is indirectly exposed to the risks associated with the Subsidiary’s investments. The commodity-related instruments held by a Subsidiary are generally similar to those that are permitted to be held by the applicable Fund and are subject to the same risks that apply to similar investments if held directly by the Fund. A Subsidiary, however, is not registered under the 1940 Act and will not be subject to all of the investor protections of the 1940 Act. Thus, the Dynamic Asset Allocation and Multi-Asset Real Return Funds, as investors in their own Subsidiary, will not have all of the protections offered to investors in registered investment companies.

However, each Fund wholly owns and controls its respective Subsidiary, and the Funds and the Subsidiaries are all managed by SIMC, making it unlikely that the Subsidiary will take action contrary to the interests of the applicable Fund or its shareholders. While a Subsidiary has its own Board of Directors (“Board”) that is responsible for overseeing the operations of such Subsidiary, the respective Fund’s Board has oversight responsibility for the investment activities of the Fund, including its investment in the respective Subsidiary, and the Fund’s role as the sole shareholder of such Subsidiary. It is not currently expected that shares of the Subsidiary will be sold or offered to investors other than the respective Fund.

Changes in the laws of the United States and/or the Cayman Islands or governmental interpretation of such laws, under which the Fund and the Subsidiary, respectively, are organized, could result in the inability of the Fund and/or its respective Subsidiary to operate as intended and could negatively affect the Fund and its shareholders. For example, Cayman Islands law does not currently impose any income, corporate or capital gains tax, estate duty, inheritance tax, gift tax or withholding tax on the Subsidiaries. If Cayman Islands law changes such that the Subsidiaries must pay Cayman Islands governmental authority taxes, Fund shareholders would likely suffer decreased investment return.

3. CREDIT DERIVATIVES

A Fund may use credit default 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.

SEI Institutional Investments Trust

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.

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 seller of protection and a credit event were to occur. Those credit default swaps (“CDS”) for which the Fund is providing protection at the balance sheet date are summarized as follows ($ Thousands):

Emerging Markets Debt Fund Maximum Potential Amount of Future Payments by Contract Term
		0-6 Months		6-12 Months		1-5 Years		5-10 Years		>10 Years	Total
Current credit spread* on underlying (in basis points)
0-300	$	—	$	—	$	—	$	—	$	—	$	—

Greater than 400		—		—		—		—		—		—
Total	$	—	$	—	$	700	$	—	$	—	$	700

* The credit spread on the underlying asset is generally indicative of the current status of the underlying risk of the Fund having to perform. The spread also reflects the cost of buying/selling protection and may include upfront payments required to be made to enter into a contract. Higher credit spreads with a shorter contract term is indicative of a higher likelihood of performance by the Fund.

Multi-Asset Real Return Fund Maximum Potential Amount of Future Payments by Contract Term
		0-6 Months		6-12 Months		1-5 Years		5-10 Years		>10 Years	Total
Current credit spread* on underlying (in basis points)

The credit spread disclosed above for each reference obligation where the Fund is the seller of protection is a representation of the current payment/performance risk of the swap.

SEI Institutional Investments Trust

A Fund is subject to various netting arrangements with select counterparties (“Master Agreements”). Master Agreements govern the terms of certain transactions, and reduce the counterparty risk associated with relevant transactions by specifying credit protection mechanisms and providing standardization that improves legal certainty. Since different types of transactions have different mechanics and are sometimes traded out of different legal entities of a particular counterparty organization, each type of transaction may be covered by a different Master Agreement, resulting in the need for multiple agreements with a single counterparty. As the Master Agreements are specific to unique operations of different asset types, they allow a Fund to close out and net its total exposure to a specific counterparty entity in the event of a default with respect to all the transactions governed under a single agreement with a specific counterparty entity.

Master Agreements can also help limit counterparty risk by specifying collateral posting arrangements at pre-arranged exposure levels. Under the Master Agreements, collateral is routinely transferred if the total net exposure to certain transactions (net of existing collateral already in place) governed under the relevant Master Agreement with a counterparty in a given account exceeds a specified threshold, which typically ranges from zero to $250,000 depending on the counterparty and the type of Master Agreement. United States Treasury Securities and U.S. dollar cash are generally the preferred forms of collateral. Securities and cash pledged as collateral are reflected as assets on the Statements of Assets and Liabilities/Consolidated Statements of Assets and Liabilities as either a component of investments at value (securities) or deposits due from counterparties (cash). Cash collateral received is not typically held in a segregated account and as such is reflected as a liability on the Statements of Assets and Liabilities/Consolidated Statements of Assets and Liabilities as deposits due to counterparties. The market value of any securities received as collateral is not reflected as a component of net asset value. A Fund’s overall exposure to

counterparty risk can change substantially within a short period, as it is affected by each transaction subject to the relevant Master Agreement.

Customer Account Agreements and related addendums govern exchange traded derivatives transactions such as futures, options on futures, and centrally cleared swaps. Exchange traded derivative transactions require posting of initial margin as determined by each relevant clearing agency which is segregated at a broker account registered with the Commodities Futures Trading Commission (“CFTC”), or the applicable regulator. In the US, counterparty risk is significantly reduced as creditors of the futures broker do not have claim to Fund assets in the segregated account. Additionally, portability of exposure in the event of default further reduces risk to the Funds. Variation margin, or changes in market value, are exchanged daily, but may not be netted between futures and cleared OTC derivatives. Refer to each Fund’s Statement of Assets and Liabilities or Consolidated Statement of Assets and Liabilities for market value, variation margin, and collateral of exchange-traded or centrally cleared financial derivative instruments.

International Swaps and Derivatives Association, Inc. Master Agreements and Credit Support Annexes (“ISDA Master Agreements”) govern OTC financial derivative transactions entered into by a Fund and select counterparties. ISDA Master Agreements maintain provisions for general obligations, representations, agreements, collateral and events of default or termination. Events of termination include conditions that may entitle counterparties to elect to terminate early and cause settlement of all outstanding transactions under the applicable ISDA Master Agreement.

Any election to terminate early could be material to the financial statements. In limited circumstances, the ISDA Master Agreement may contain additional provisions that add additional counterparty protection beyond coverage of existing daily exposure if the counterparty has a decline in credit quality below a predefined level. These amounts, if any, may be segregated with a third party custodian.

SEI Investments Global Funds Services (the “Administrator”) serves as administrator to the Funds. The Administrator provides certain administrative and shareholder servicing for an annual fee of 0.05% of the average daily net assets of each Fund. For the year ended May 31, 2025, the Administrator has voluntarily agreed to waive all of its fees. The Funds’ Administrator may discontinue all or part of these voluntary waivers at any time.

SEI Investments Distribution Co. (the “Distributor”), a wholly owned subsidiary of SEI Investments Company (“SEI”), serves as each Fund’s Distributor pursuant to a Distribution Agreement with the Trust.

Other — The Distribution Agreement between the Distributor and the Trust provides that the Distributor may receive compensation on fund transactions effected for the Trust in accordance with Securities and Exchange Commission (“SEC”) rules. Accordingly, it is expected that fund transactions may result in brokerage commissions being paid to the Distributor. The SEC rules require that such commissions not exceed usual and customary commissions.

Payments to Affiliates — Certain officers and/or trustees of the Trust are also officers and/or Directors of the Distributor, the Adviser and/or the Administrator. The Trust pays each unaffiliated Trustee an annual fee for attendance at quarterly and interim meetings. Compensation of officers and affiliated Trustees of the Trust is paid by the Distributor or Administrator.

A portion of the services provided by the Chief Compliance Officer (“CCO”) and his staff, whom are employees of the Administrator, are paid for by the Trust as incurred. The services include regulatory oversight of the Trust’s Adviser, sub-advisers and service providers as required by SEC regulations.

LSV Asset Management (partially-owned subsidiary of SIMC) serves as a sub-adviser to the Large Cap, Small Cap, Small/Mid Cap Equity, U.S. Managed Volatility and Global Managed Volatility Funds. For this service, LSV Asset Management is entitled to receive a fee from SIMC. Such fees for the year ended May 31, 2025, were as follows ($ Thousands):

Large Cap Fund	$	220
Small Cap Fund		389
Small/Mid Cap Equity Fund		1,055
U.S. Managed Volatility Fund		876
Global Managed Volatility Fund		2,069

Fees Paid Indirectly — The Funds may direct certain fund trades to the Distributor who pays a portion of each Fund’s expenses. Accordingly, the expenses reduced, which were used to pay third party expenses, can be found on the Statements of Operations or Consolidated Statement of Operations and the effect on each Fund’s expense ratio, as

a percentage of each Fund’s average daily net assets for the year ended May 31, 2025, can be found on the Financial Highlights or Consolidated Financial Highlights.

Investment in Affiliated Security — The Funds may invest in the SEI Daily Income Trust (“SDIT”) Government Fund, an affiliated money market fund to manage excess cash or to serve as margin or collateral for derivative positions.

A Fund may purchase companies with which it is affiliated to the extent these companies are represented in its benchmark index.

Interfund Lending — The SEC has granted an exemption that permits the Trust to participate in an interfund lending program (“The Program”) with existing or future investment companies registered under the 1940 Act that are advised by SIMC (the “SEI Funds”). The Program allows the SEI Funds to lend money to and borrow money from each other for

temporary or emergency purposes. Participation in The Program is voluntary for both borrowing and lending funds.

Interfund loans may be made only when the rate of interest to be charged is more favorable to the lending fund than an investment in overnight repurchase agreements (“Repo Rate”), and more favorable to the borrowing fund than the rate of interest that would be charged by a bank for short-term borrowings (“Bank Loan Rate”). The Bank Loan Rate will be determined using a formula annually reviewed by the SEI Funds’ Board of Trustees. The interest rate imposed on inter-fund loans is the average of the Repo Rate and the Bank Loan Rate.

As of and during the year ended May 31, 2025, the Trust did not participate in the program.

9. FEDERAL TAX INFORMATION

It is each Fund’s intention to qualify for or 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.

The Dynamic Asset Allocation and Multi-Asset Real Return Funds have investments in commodity linked derivatives through wholly owned Cayman Island subsidiaries (CFCs). On March 19, 2019, the Treasury published final regulation that allows regulated investment companies investing in CFCs to treat the required income inclusion as qualifying income.

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 U.S. 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 or distributable earnings (loss), as appropriate, in the period that the differences arise.

For Federal income tax purposes, the cost of investments owned at May 31, 2025, and the net realized gains or losses on investments sold for the period were not materially different from amounts reported for financial reporting purposes. These differences are primarily due to investments in partnerships, passive foreign investment companies, defaulted bond 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, 2025, was as follows:

Management has analyzed the Funds’ tax positions taken on Federal income tax returns for all open tax years and has concluded that as of May 31, 2025, no provision for income tax would be required in the Funds’ financial statements. The Funds’ 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.

Withholding taxes on foreign dividends have been provided for in accordance with the Funds’ understanding of the applicable country’s tax rules and rates. The Funds or their agent files withholding tax reclaims in certain jurisdictions to recover certain amounts previously withheld. The Funds may record a reclaim receivable based on collectability, which includes factors such as the jurisdiction’s applicable laws, payment history and market convention. Professional fees paid to those that provide assistance in receiving the tax reclaims, which generally are contingent upon successful receipt of reclaimed amounts, are recorded in Professional Fees on the Statements of Operations once the amounts are due. The professional fees related to pursuing these tax reclaims are not subject to the Adviser’s expense limitation agreement.

10. 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, High Yield Bond, Long Duration, Long Duration Credit, Ultra Short Duration Bond, Limited Duration Bond, Intermediate Duration Credit and Multi-Asset Real Return Funds’ investments will change in response to interest rate changes and other factors. During periods of falling interest rates, the values of fixed income securities generally rise. Conversely, during periods of rising interest rates, the values of such securities generally decline. Changes by recognized rating agencies in the ratings of any fixed income security and in the ability of an issuer to make payments of interest and principal may also affect the value of these investments.

The World Equity Ex-US, Screened World Equity Ex-US, Emerging Markets Equity 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.

The following descriptions provide additional information about some of the risks of investing in the Funds. A more complete description of principal risks is included in each Fund’s prospectus under the heading “Principal Risks”.

American Depositary Receipts (ADRs) Risk — ADRs are certificates evidencing ownership of shares of a foreign issuer that are issued by depositary banks and generally trade on an established market. ADRs are subject to many of the risks associated with investing directly in foreign securities, including, among other things, political, social and economic developments abroad, currency movements and different legal, regulatory and tax environments.

Asset-Backed Securities Risk — Payment of principal and interest on asset-backed securities is dependent largely on the cash flows generated by the assets backing the securities. Securitization trusts generally do not have any assets or sources of funds other than receivables and

related property they own, and asset-backed securities are generally not insured or guaranteed by the related sponsor or any other entity. Asset-backed securities may be more illiquid than more conventional types of fixed income securities that the Fund may acquire.

Bank Loans Risk—With respect to bank loans, the Fund will assume the credit risk of both the borrower and the lender that is selling the participation. The Fund may also have difficulty disposing of bank loans because, in certain cases, the market for such instruments is not highly liquid.

Below Investment Grade Securities (Junk Bonds) Risk — Fixed income securities rated below investment grade (junk bonds) involve greater risks of default or downgrade and are generally more volatile than investment grade securities because the prospect for repayment of principal and interest of many of these securities is speculative. Because these securities typically offer a higher rate of return to compensate investors for these risks, they are sometimes referred to as “high yield bonds,” but there is no guarantee that an investment in these securities will result in a high rate of return.

Commercial Paper Risk — Commercial paper is a short-term obligation with a maturity generally ranging from one to 270 days and is issued by U.S. or foreign companies or other entities in order to finance their current operations. Such investments are unsecured and usually discounted from their value at maturity. The value of commercial paper may be affected by changes in the credit rating or financial condition of the issuing entities and will tend to fall when interest rates rise and rise when interest rates fall. Asset-backed commercial paper may be issued by structured investment vehicles or other conduits that are organized to issue the commercial paper and to purchase trade receivables or other financial assets. The repayment of asset-backed commercial paper depends primarily on the cash collections received from such an issuer’s underlying asset portfolio and the issuer’s ability to issue new asset-backed commercial paper.

Commodity Investments and Derivatives Risk — Commodity investments and derivatives may be more volatile and less liquid than direct investments in the underlying commodities themselves. Commodity related equity returns can also be affected by the issuer’s financial structure or the performance of unrelated businesses. The value of a commodity investment or a derivative investment in commodities is typically based upon the price movements of a physical commodity, a commodity futures contract or commodity index or some other readily measurable economic variable that is dependent upon changes in the value of commodities or the commodities

426

SEI Institutional Investments Trust

markets. The value of these securities will rise or fall in response to changes in the underlying commodity or related benchmark or investment, changes in interest rates or factors affecting a particular industry or commodity, such as natural disasters, weather and U.S. and international economic, political and regulatory developments.

Commodity-Linked Securities Risk — Investments in commodity-linked securities may be more volatile and less liquid than direct investments in the underlying commodities themselves. Commodity-related equity returns can also be affected by the issuer’s financial structure or the performance of unrelated businesses.

Convertible and Preferred Securities Risk — Convertible and preferred securities have many of the same characteristics as stocks, including many of the same risks. In addition, convertible bonds may be more sensitive to changes in interest rates than stocks. Convertible bonds may also have credit ratings below investment grade, meaning that they carry a higher risk of failure by the issuer to pay principal and/or interest when due.

Corporate Fixed Income Securities Risk — Corporate fixed income securities respond to economic developments, especially changes in interest rates, as well as perceptions of the creditworthiness and business prospects of individual issuers.

Credit Risk — The risk that the issuer of a security or the counterparty to a contract will default or otherwise become unable to honor a financial obligation.

Currency Risk — As a result of the Fund’s investments in securities denominated in, and/or receiving revenues in, foreign currencies, the Fund will be subject to currency risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency hedged. In either event, the dollar value of an investment in the Fund would be adversely affected. Due to the Fund’s active positions in currencies, it will be subject to the risk that currency exchange rates may fluctuate in response to, among other things, changes in interest rates, intervention (or failure to intervene) by U.S. or foreign governments, central banks or supranational entities, or by the imposition of currency controls or other political developments in the United States or abroad.

Current Market Condition Risk — Current market conditions risk is the risk that a particular investment, or shares of the Funds in general, may fall in value due to current market conditions. Although interest rates were unusually low in recent years in the U.S. and abroad, in 2022, the Federal Reserve and certain foreign central banks raised interest rates as part of their efforts to address rising inflation. The

Federal Reserve and certain foreign central banks recently began to lower interest rates, though economic or other factors, such as inflation, could stop such changes. It is difficult to accurately predict the pace at which interest rates might change, the timing, frequency or magnitude of any such changes in interest rates, or when such changes might stop or again reverse course. Unexpected changes in interest rates could lead to significant market volatility or reduce liquidity in certain sectors of the market. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact on the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Funds’ investments and operations. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes and other matters. If any geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Funds’ assets may go down. The COVID-19 global pandemic, or any future public health crisis, and the ensuing policies enacted by governments and central banks have caused and may continue to cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. Advancements in technology may also adversely impact markets and the overall performance of the Funds. These events, and any other future events, may adversely affect the prices and liquidity of the Funds’ investments and could result in disruptions in the trading markets.

Derivatives Risk — The Fund’s use of futures contracts, forwards contracts, options and swaps is subject to market risk, leverage risk, correlation risk and liquidity risk. Leverage risk and liquidity risk are described below and market risk is described above. Many OTC derivative instruments will not have liquidity beyond the counterparty to the instrument. Correlation risk is the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. The Fund’s use of forward contracts, options and swaps is also subject to credit risk and valuation risk. Credit risk is described below. Valuation risk is the risk that the derivative may be difficult to value and/or valued incorrectly. Each of these risks could cause the Fund to lose more than the principal amount invested in a derivative instrument. Some derivatives have the potential for unlimited loss, regardless of the size of the Fund’s initial investment. The other parties to certain

SEI Institutional Investments Trust

427

NOTES TO FINANCIAL STATEMENTS / NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

May 31, 2025

derivative contracts present the same types of credit risk as issuers of fixed income securities. The Fund’s use of derivatives may also increase the amount of taxes payable by shareholders. The Fund’s use of may also increase the amount of taxes payable by shareholders. Both U.S. and non-U.S. regulators have adopted and implemented regulations governing derivatives markets, the ultimate impact of which remains unclear.

Duration Risk — The longer-term securities in which the Fund may invest are more volatile. A portfolio with a longer average portfolio duration is more sensitive to changes in interest rates than a portfolio with a shorter average portfolio duration.

Equity Market Risk — The risk that the market value of a security may move up and down, sometimes rapidly and unpredictably. Market risk may affect a single issuer, an industry, a sector or the equity or bond market as a whole. Equity markets may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Similarly, environmental and public health risks, such as natural disasters, epidemics, pandemics or widespread fear that such events may occur, may impact markets adversely and cause market volatility in both the short- and long-term.

Exchange-Traded Funds (ETFs) Risk — The risks of owning shares of an ETF generally reflect the risks of owning the underlying securities the ETF is designed to track, although lack of liquidity in an ETF could result in its value being more volatile than the underlying portfolio securities. When the Fund invests in an ETF, in addition to directly bearing the expenses associated with its own operations, it will bear a pro rata portion of the ETF’s expenses.

Extension Risk — The risk that rising interest rates may extend the duration of a fixed income security, typically reducing the security’s value.

Fixed Income Market Risk — The prices of the Fund’s fixed income securities respond to economic developments, particularly interest rate changes, as well as to perceptions about the creditworthiness of individual issuers, including governments and their agencies. Generally, the Fund’s fixed income securities will decrease in value if interest rates rise and vice versa. In a low interest rate environment, risks associated with rising rates are heightened. Declines in dealer market-making capacity as a result of structural or regulatory changes could decrease liquidity and/or increase volatility in the fixed income markets. Markets for fixed income securities may decline significantly in response to adverse issuer, political, regulatory, market, economic

or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Similarly, environmental and public health risks, such as natural disasters, epidemics, pandemics or widespread fear that such events may occur, may impact markets adversely and cause market volatility in both the short- and long-term. In response to these events, the Fund’s value may fluctuate and/or the Fund may experience increased redemptions from shareholders, which may impact the Fund’s liquidity or force the Fund to sell securities into a declining or illiquid market.

Foreign Investment/Emerging and Frontier Markets Risk — The risk that non-U.S. securities may be subject to additional price volatility, illiquidity and decreases in value due to, among other things, political, social and economic developments abroad, government ownership or control of portions of the private sector or certain companies, trade barriers and currency movements, exchange controls and managed adjustments in relative currency values, and different or new and unsettled securities and tax markets, laws and regulations. These additional risks may be heightened with respect to emerging market countries because political turmoil and rapid changes in economic conditions are more likely to occur in these countries. These risks may be magnified further with respect to “frontier market countries,” which are a subset of emerging market countries with even smaller national economies.

Foreign Sovereign Debt Securities Risk — The risks that (i) the governmental entity that controls the repayment of sovereign debt may not be willing or able to repay the principal and/or interest when it becomes due, because of factors such as debt service burden, political constraints, cash flow problems and other national economic factors; (ii) governments may default on their debt securities, which may require holders of such securities to participate in debt rescheduling or additional lending to defaulting governments; and (iii) there is no bankruptcy proceeding by which defaulted sovereign debt may be collected in whole or in part.

Inflation Protected Securities Risk — The value of inflation protected securities, including TIPS, generally will fluctuate in response to changes in “real” interest rates, generally decreasing when real interest rates rise and increasing when real interest rates fall. Real interest rates represent nominal (or stated) interest rates reduced by the expected impact of inflation. In addition, interest payments on inflation-indexed securities will generally vary up or down along with the rate of inflation.

Interest Rate Risk — The risk that a change in interest rates will cause a fall in the value of fixed income

428

SEI Institutional Investments Trust

securities, including U.S. Government securities, in which a Fund invests. Generally, the value of the Fund’s fixed income securities will vary inversely with the direction of prevailing interest rates. Changing interest rates may have unpredictable effects on the markets and may affect the value and liquidity of instruments held by the Fund. Although U.S. Government securities are considered to be among the safest investments, they are not guaranteed against price movements due to changing interest rates.

A low interest rate environment may present greater interest rate risk, because there may be a greater likelihood of rates increasing and rates may increase more rapidly.

Investing in Limited Recourse Obligations Risk — Collateralized debt obligation (CDO) and collateralized loan obligation (CLO) securities are non-recourse obligations of their issuer payable solely from the related underlying collateral or its proceeds. Therefore, as a holder of CDOs and CLOs, the Fund must rely only on distributions on the underlying collateral or related proceeds for payment. If distributions on the underlying collateral are insufficient to make payments on the CDO or CLO securities, no other assets will be available for payment of the deficiency. As a result, the amount and timing of interest and principal payments in respect of CDO and CLO securities will depend on the performance and characteristics of the related underlying collateral.

Investment Company Risk — When the Fund invests in an investment company, including closed-end funds and ETFs, in addition to directly bearing the expenses associated with its own operations, it will bear a pro rata portion of the investment company’s expenses. Further, while the risks of owning shares of an investment company generally reflect the risks of owning the underlying investments of the investment company, the Fund may be subject to additional or different risks than if the Fund had invested directly in the underlying investments. For example, the lack of liquidity in an ETF could result in its value being more volatile than that of the underlying portfolio securities. Closed-end investment companies issue a fixed number of shares that trade on a stock exchange or over-the-counter at a premium or a discount to their net asset value. As a result, a closed-end fund’s share price fluctuates based on what another investor is willing to pay rather than on the market value of the securities in the fund.

Investment in the Subsidiary Risk — The Subsidiary is not registered under the Investment Company Act of 1940, as amended (“the 1940 Act”), and, unless otherwise noted in this prospectus, is not subject to all of the investor protections of the 1940 Act. Thus, the Fund, as an investor in the Subsidiary, will not have all of the protections

offered to investors in registered investment companies. In addition, changes in the laws of the United States and/or the Cayman Islands, under which the Fund and the Subsidiary, respectively, are organized, could result in the inability of the Fund and/or the Subsidiary to operate as intended and could negatively affect the Fund and its shareholders.

Investment Style Risk — The risk that large capitalization securities may underperform other segments of the equity markets or the equity markets as a whole.

Large Capitalization Risk — The risk that larger, more established companies may be unable to respond quickly to new competitive challenges such as changes in technology and consumer tastes. Larger companies also may not be able to attain the high growth rates of successful smaller companies.

Leverage Risk — The Funds’ use of derivatives may result in the Funds’ total investment exposure substantially exceeding the value of its portfolio securities and the Funds’ investment returns depending substantially on the performance of securities that the Funds may not directly own. The use of leverage can amplify the effects of market volatility on the Funds’ share price and may also cause the Funds to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations. The Funds’ use of leverage may result in a heightened risk of investment loss.

Liquidity Risk — The risk that certain securities may be difficult or impossible to sell at the time and the price that the Fund would like. The Fund may have to lower the price of the security, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Fund management or performance.

Market Risk — The risk that the market value of a security may move up and down, sometimes rapidly and unpredictably. Market risk may affect a single issuer, an industry, a sector or the equity market as a whole. Equity markets may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Similarly, environmental and public health risks, such as natural disasters, epidemics, pandemics or widespread fear that such events may occur, may impact markets adversely and cause market volatility in both the short- and long-term.

Mortgage-Backed Securities Risk — Mortgage-backed securities are affected significantly by the rate of prepayments and modifications of the mortgage loans

SEI Institutional Investments Trust

429

NOTES TO FINANCIAL STATEMENTS / NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

May 31, 2025

backing those securities, as well as by other factors such as borrower defaults, delinquencies, realized or liquidation losses and other shortfalls. Mortgage-backed securities are particularly sensitive to prepayment risk, which is described below, given that the term to maturity for mortgage loans is generally substantially longer than the expected lives of those securities; however, the timing and amount of prepayments cannot be accurately predicted. The timing of changes in the rate of prepayments of the mortgage loans may significantly affect the Fund’s actual yield to maturity on any mortgage-backed securities, even if the average rate of principal payments is consistent with the Fund’s expectation. Along with prepayment risk, mortgage-backed securities are significantly affected by interest rate risk, which is described above. In a low interest rate environment, mortgage loan prepayments would generally be expected to increase due to factors such as refinancings and loan modifications at lower interest rates. In contrast, if prevailing interest rates rise, prepayments of mortgage loans would generally be expected to decline and therefore extend the weighted average lives of mortgage-backed securities held or acquired by the Fund.

Mortgage Dollar Rolls Risk — Mortgage dollar rolls are transactions in which the Fund sells securities (usually mortgage-backed securities) and simultaneously contracts to repurchase substantially similar, but not identical, securities on a specified future date. If the broker-dealer to whom the Fund sells the security becomes insolvent, the Fund’s right to repurchase the security may be restricted. Other risks involved in entering into mortgage dollar rolls include the risk that the value of the security may change adversely over the term of the mortgage dollar roll and that the security the Fund is required to repurchase may be worth less than the security that the Fund originally held.

Municipal Securities Risk — Municipal securities, like other fixed income securities, rise and fall in value in response to economic and market factors, primarily changes in interest rates, and actual or perceived credit quality. Rising interest rates will generally cause municipal securities to decline in value. Longer-term securities respond more sharply to interest rate changes than do shorter-term securities. A municipal security will also lose value if, due to rating downgrades or other factors, there are concerns about the issuer’s current or future ability to make principal or interest payments. State and local governments rely on taxes and, to some extent, revenues from private projects financed by municipal securities, to pay interest and principal on municipal debt. Poor statewide or local economic results or changing political sentiments may reduce tax revenues and increase the expenses of municipal issuers, making it more difficult for them to repay principal and to make interest payments on securities owned by the Fund. Actual

or perceived erosion of the creditworthiness of municipal issuers may reduce the value of the Fund’s holdings. As a result, the Fund will be more susceptible to factors that adversely affect issuers of municipal obligations than a mutual fund that does not have as great a concentration in municipal obligations.

Non-Diversified Risk — The Emerging Markets Debt and Multi-Asset Real Return Funds are non-diversified, which means that they may invest in the securities of relatively few issuers. As a result, the Funds may be more susceptible to a single adverse economic or political occurrence affecting one or more of these issuers and may experience increased volatility due to its investments in those securities. However, the Funds intend to satisfy the asset diversification requirements under Subchapter M of the Internal Revenue Code of 1986, as amended, for classification as a regulated investment company.

Opportunity Risk — The risk of missing out on an investment opportunity because the assets necessary to take advantage of it are tied up in other investments.

Participation Notes (P-Notes) Risk — P-Notes are participation interest notes that are issued by banks or broker-dealers and are designed to offer a return linked to a particular underlying equity, debt, currency or market. Investments in P-Notes involve the same risks associated with a direct investment in the underlying foreign companies or foreign securities markets that they seek to replicate. However, there can be no assurance that the trading price of P-Notes will equal the underlying value of the foreign companies or foreign securities markets that they seek to replicate.

Portfolio Turnover Risk — Due to its investment strategy, the Fund may buy and sell securities frequently. This may result in higher transaction costs and taxes subject to ordinary income tax rates as opposed to more favorable capital gains rates, which may affect the Fund's performance.

Prepayment Risk — The risk that, in a declining interest rate environment, fixed income securities with stated interest rates may have the principal paid earlier than expected, requiring the Fund to invest the proceeds at generally lower interest rates.

Private Placements Risk — Investment in privately placed securities may be less liquid than in publicly traded securities. Although these securities may be resold in privately negotiated transactions, the prices realized from these sales could be less than those originally paid by the Fund or less than what may be considered the fair value of such securities. Further, companies whose securities are not publicly traded may not be subject to the disclosure

430

SEI Institutional Investments Trust

and other investor protection requirements that might be applicable if their securities were publicly traded.

Quantitative Investing Risk — A quantitative investment style generally involves the use of computers to implement a systematic or rules-based approach to selecting investments based on specific measurable factors. Due to the significant role technology plays in such strategies, they carry the risk of unintended or unrecognized issues or flaws in the design, coding, implementation or maintenance of the computer programs or technology used in the development and implementation of the quantitative strategy.

Real Estate Industry Risk — Securities of companies principally engaged in the real estate industry may be subject to the risks associated with direct ownership of real estate. Risks commonly associated with the direct ownership of real estate include fluctuations in the value of underlying properties, defaults by borrowers or tenants, changes in interest rates and risks related to general or local economic conditions.

Redemption Risk — The Funds may experience periods of heavy redemptions that could cause the Funds to liquidate its assets at inopportune times or at a loss or depressed value, particularly during periods of declining or illiquid markets.

REITs Risk — REITs are trusts that invest primarily in commercial real estate or real estate-related loans. The Fund’s investments in REITs will be subject to the risks associated with the direct ownership of real estate. Risks commonly associated with the direct ownership of real estate include fluctuations in the value of underlying properties, defaults by borrowers or tenants, changes in interest rates and risks related to general or local economic conditions. Some REITs may have limited diversification and may be subject to risks inherent in financing a limited number of properties.

Repurchase Agreements and Reverse Repurchase Agreements Risk — In the event of the insolvency of the counterparty to a repurchase agreement or reverse repurchase agreement, recovery of the repurchase price owed to the Fund or, in the case of a reverse repurchase agreement, the securities sold by the Fund, may be delayed. Because reverse repurchase agreements may be considered to be the practical equivalent of borrowing funds, they constitute a form of leverage. If the Fund reinvests the proceeds of a reverse repurchase agreement at a rate lower than the cost of the agreement, entering into the agreement will lower the Fund’s yield.

Sampling Risk — The Fund may not fully replicate the benchmark index and may hold securities not included in

the index. As a result, the Fund may not track the return of its benchmark index as well as it would have if the Fund purchased all of the securities in its benchmark index.

Short Sales Risk — A short sale involves the sale of a security that the Fund does not own in the expectation of purchasing the same security (or a security exchangeable therefore) at a later date at a lower price. Short sales expose the Fund to the risk that it will be required to buy the security sold short (also known as “covering” the short position) at a time when the security has appreciated in value, thus resulting in a loss to the Fund. Investment in short sales may also cause the Fund to incur expenses related to borrowing securities. Reinvesting proceeds received from short selling may create leverage, which can amplify the effects of market volatility on the Fund’s share price. In addition, shorting a future contract may require posting only a margin that may amount to less than the notional exposure of the contract. Such a practice may exacerbate the loss in a case of adverse price action.

Small and Medium Capitalization Risk — Small and medium capitalization companies in which the Fund may invest may be more vulnerable to adverse business or economic events than larger, more established companies. In particular, small and medium capitalization companies may have limited product lines, markets and financial resources and may depend upon a relatively small management group. Therefore, small and medium capitalization stocks may be more volatile than those of larger companies. Small and medium capitalization stocks may be traded over-the-counter (OTC). OTC stocks may trade less frequently and in smaller volume than exchange listed stocks and may have more price volatility than that of exchange-listed stocks.

Social Investment Criteria Risk — The Screened World Equity Ex-US Fund’s portfolio is subject to certain social investment criteria, including its anti-BDS approach. As a result, the Sub-Advisers will avoid purchasing certain securities for social reasons when it is otherwise economically advantageous to purchase those securities or may sell certain securities for social reasons when it is otherwise economically advantageous to hold those securities. In general, the application of the Fund’s social investment criteria may affect the Fund’s exposure to certain industries, sectors and geographic areas, which may affect the financial performance of the Fund, positively or negatively, depending on whether these industries or sectors are in or out of favor.

Tax Risk — The Fund may gain most of its exposure to the commodities markets through its investment in the Subsidiary, which invests in commodity investments and derivative instruments. To the extent the Fund invests in such instruments directly, it will seek to restrict its income

from commodity-linked derivative instruments that do not generate qualifying income, such as commodity-linked swaps, to a maximum of 10% of its gross income (when combined with its other investments that produce non-qualifying income) to comply with the qualifying income test necessary for the Fund to qualify as a regulated investment company under Subchapter M of the Internal Revenue Code of 1986, as amended. The tax treatment of certain commodity linked derivative instruments may be affected by future regulatory or legislative changes that could affect the character, timing and/or amount of the Fund’s taxable income or gains and distributions.

Tracking Error Risk — The risk that the Fund’s performance may vary substantially from the performance of the benchmark index it tracks as a result of cash flows, Fund expenses, imperfect correlation between the Fund’s investments and the index’s components and other factors.

U.S. Government Securities Risk — Although U.S. Government securities are considered to be among the safest investments, they are still subject to the credit risk of the U.S. Government and are not guaranteed against price movements due to changing interest rates. Obligations issued by some U.S. Government agencies are backed by the U.S. Treasury, while others are backed solely by the ability of the agency to borrow from the U.S. Treasury or by the agency’s own resources. No assurance can be given that the U.S. Government will provide financial support to its agencies and instrumentalities if it is not obligated by law to do so.

Warrants Risk — Warrants are instruments that entitle the holder to buy an equity security at a specific price for a specific period of time. Warrants may be more speculative than other types of investments. The price of a warrant may be more volatile than the price of its underlying security, and a warrant may offer greater potential for capital appreciation as well as capital loss. A warrant ceases to have value if it is not exercised prior to its expiration date.

Please refer to each Fund’s current prospectus for additional disclosure regarding the risks associated with investing in the Funds. The foregoing is not intended to be a complete discussion of the risks associated with the investment strategies of the Funds.

11. SECURITIES LENDING

To the extent consistent with its Investment Objective and Strategies, a 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, LP, and the Fund bears all of the gains and losses on such investment. There is no guarantee that these investments will not lose value.

During the year ended May 31, 2025, the Funds discontinued using the Securities Lending Program.

SPTC holds the vast majority of shares in the Funds as custodian for shareholders that are clients of the advisors and financial planners. SPTC maintains accounts at SEI Institutional Transfer Agency (“SITA”), and operates in an omnibus fund account environment.

13. SEGMENT REPORTING

In this reporting period, the Funds adopted the Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) 2023-07, Segment Reporting (Topic 280) – “Improvements to Reportable Segment Disclosures” (“ASU 2023-07”). Adoption of the new standard impacted financial statement disclosures only and did not affect the Funds’ financial position or the results of its operations. An operating segment is defined in Topic 280 as a component of a public entity that engages in business activities from which it may recognize revenues and incur expenses, has operating results that are regularly reviewed by the public entity’s chief operating decision maker (“CODM”) to make decisions about resources to be allocated to the segment and assess its performance, and has discrete financial information available. SIMC acts as the Funds’ CODM. The CODM has determined that the Funds represent a single operating segment, as the CODM monitors the operating results of the Funds as a whole and the Funds’ long-term strategic asset allocation

is pre-determined in accordance with the terms of its prospectus, based on a defined investment strategy which is executed by the Funds’ portfolio managers as a team. The financial information in the form of the Funds’ schedules of investments, total returns, expense ratios and changes in net assets (i.e., changes in net assets resulting from operations, subscriptions and redemptions), which are used by the CODM to assess the segment’s performance versus the Funds’ comparative benchmarks and to make resource allocation decisions for the Funds’ single segment, is consistent with that presented within the Funds’ financial statements. Segment assets are reflected on the accompanying Statements of Assets and Liabilities as “total assets” and significant segment expenses are listed on the accompanying Statements of Operations.

14. 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 disclosure and/or adjustments were required to the financial statements.

Item 10. Remuneration Paid to Directors, Officers, and Others of Open-End Management Investment Companies.

Included within the Statement(s) of Operations of the financial statements.

Item 11. Statement Regarding Basis for Approval of Investment Advisory Contract.

SEI Institutional Investments Trust (the “Trust”) and SEI Investments Management Corporation (“SIMC”) have entered into an investment advisory agreement (the “Advisory Agreement”), pursuant to which SIMC provides investment advisory services to the series of the Trust (the “Funds”). Pursuant to separate sub-advisory agreements with SIMC (the “Sub-Advisory Agreements” and, together with the Advisory Agreement, the “Investment Advisory Agreements”), and under the supervision of SIMC and the Trust’s Board of Trustees (each member, a “Trustee” and, collectively, the “Trustees” or the “Board”), the sub-advisers (each, a “Sub-Adviser” and collectively, the “Sub-Advisers”) provide security selection and certain other advisory services with respect to all or a discrete portion of the assets of the Funds. The Sub-Advisers are also responsible for managing their employees who provide services to the 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 a Fund’s Investment Advisory Agreements be specifically approved by the vote of a majority of the outstanding shareholders of the Funds and 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 (or otherwise, as consistent with applicable laws, regulations and related guidance and relief) at a meeting called for such purpose. In addition, the 1940 Act requires that the continuation or renewal of any Investment Advisory Agreement be approved at least annually (after an initial period of up to two years), which also requires the vote of a majority of the Board, including a majority of the Independent Trustees. In the case of the initial approval of a Sub-Advisory Agreement, only the approval of a majority of the Board, including a majority of the Independent Trustees, is required, pursuant to an exemptive order that has been granted to the Trust by the Securities and Exchange Commission. In connection with their consideration of such initial approvals and renewals, 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 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 or renew an Investment Advisory Agreement.

SEI Institutional Investments Trust

OTHER INFORMATION (FORM N-CSR ITEMS 8-11) (UNAUDITED) (Continued)

Consistent with these responsibilities, the Board calls and holds meetings each year to consider whether to approve new and/or renew existing 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 and the services provided pursuant to the Investment Advisory Agreements. The Board also receives data from third parties. This information is provided 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 counsel regarding the responsibilities of Trustees in connection with their consideration of whether to approve or renew the Trust’s Investment Advisory Agreements. Finally, the Independent Trustees receive advice from independent counsel to the Independent Trustees, meet in executive sessions outside the presence of Fund management and participate in question and answer sessions with representatives of SIMC and the Sub-Advisers.

Specifically, during the course of the Trust’s fiscal year, the Board requested and received written materials from SIMC and the Sub-Advisers regarding: (i) the quality of SIMC’s and the Sub-Advisers’ investment management and other services; (ii) SIMC’s and the Sub-Advisers’ investment management personnel; (iii) SIMC’s and the Sub-Advisers’ operations and financial condition; (iv) SIMC’s and the Sub-Advisers’ brokerage practices (including any soft dollar arrangements) and investment strategies; (v) the level of the advisory fees that SIMC charges the Funds and the level of the sub-advisory fees that SIMC pays the Sub-Advisers, compared with fees each charge to comparable accounts; (vi) the advisory fees charged by SIMC and the Funds’ overall fees and operating expenses compared with peer groups of mutual funds prepared by Broadridge, an independent provider of investment company data that was engaged to prepare an assessment of the Funds in connection with the renewal of the Investment Advisory Agreements (the “Broadridge Report”); (vii) the level of SIMC’s and the Sub-Advisers’ profitability from their Fund-related operations; (viii) SIMC’s and the Sub-Advisers’ compliance program, including a description of material compliance matters and material compliance violations; (ix) SIMC’s potential economies of scale; (x) SIMC’s and the Sub-Advisers’ policies on and compliance procedures for personal securities transactions; (xi) SIMC’s and the Sub-Advisers’ expertise and resources in domestic and/or international financial markets; and (xii) the Funds’ performance over various periods of time compared with peer groups of mutual funds prepared by Broadridge and the Funds’ benchmark indexes.

At a meeting held on June 24-26, 2024, the Board approved a reduction in contractual investment advisory fees for the Emerging Markets Debt Fund and the U.S. Managed Volatility Fund. Additionally, at the December 2–4, 2024 meeting of the Board, the Trustees, including a majority of the Independent Trustees, approved a brief extension of certain Investment Advisory Agreements already in effect (unless operating under an initial two-year term) to accommodate a revised Spring meeting schedule. Typically, the Trustees renew certain Investment Advisory Agreements at the first quarterly in-person meeting of the calendar year in March. Investment Advisory Agreements regularly renewed at the March meeting expire on April 1 of the following year. Because the first quarterly in-person meeting of the Board in calendar year 2025 was held on April 1-3, certain Investment Advisory Agreements would have expired prior to the meeting, without the extension. Accordingly, the Board voted in-person at the December 2-4, 2024 meeting to extend certain Investment Advisory Agreements until the April 1-3, 2025 meeting. In evaluating whether to approve the extension, the Board considered the information made available to it throughout the course of the year. At the April 1-3, 2025 meeting, the Board evaluated certain Investment Advisory Agreements in accordance with the renewal process that it typically applies during the annual contract renewal each Spring. The Board’s approval was based on its consideration and evaluation of the factors described above, as discussed at the meeting and at prior meetings, such as the December 2-4, 2024 meeting. Also, certain Sub-Advisory Agreements were either initially approved or, if the Sub-Advisory Agreement was already in effect (unless operating under an initial two-year term), renewed at meetings of the Board held during the course of the Trust’s fiscal year on June 24–26, 2024, September 9–11, 2024, December 2–4, 2024 and April 1–3, 2025. The following discusses some, but not all, of the factors that were considered by the Board in connection with its assessment of the Investment Advisory Agreements.

Nature, Extent and Quality of Services. The Board 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 each Sub-Adviser’s personnel, experience, track record and compliance program. 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

438

SEI Institutional Investments Trust

resources of SIMC and the Sub-Advisers and their affiliates dedicated to the Funds were sufficient to support the initial approval or renewal of the Investment Advisory Agreements. In addition to advisory services, the Board considered the nature and quality of certain administrative, transfer agency and other non-investment advisory services provided to the Funds by SIMC and/or its affiliates.

Performance. In determining whether to renew SIMC’s Advisory Agreement, the Trustees considered the Funds’ performance relative to their peer groups and appropriate indexes/benchmarks. The Trustees reviewed performance information for each Fund, noting that they receive performance reports that permit them to monitor each Fund’s performance at board meetings throughout the year. As part of this review, the Trustees considered the composition of each peer group and selection criteria. In assessing Fund performance, the Trustees considered the Broadridge Report. The Broadridge Report included metrics on risk analysis, volatility versus total return, net total return and performance consistency for the Funds and a universe of comparable funds. Based on the materials considered and discussed at the meetings, the Trustees found Fund performance satisfactory, or, where performance was materially below the benchmark and/or peer group, the Trustees were satisfied with the reasons provided to explain such performance. In connection with the approval or renewal of Sub-Advisory Agreements, the Board considered the performance of the Sub-Adviser relative to appropriate indexes/benchmarks. Following evaluation, the Board concluded that, within the context of its full deliberations, the performance of the Funds was sufficient to support renewal of SIMC’s Advisory Agreement, and the performance of each Sub-Adviser was sufficient to support the approval or renewal of the Sub-Advisory Agreement.

Fees. 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 ratios in comparison to those of the Funds’ respective peer groups. In assessing Fund expenses, the Trustees considered the information in the Broadridge Report, which included various metrics related to fund expenses, including, but not limited to, contractual management fees at various asset levels, actual management fees (including transfer agent expenses), and actual total expenses for the Funds and a universe of comparable funds. Based on the materials considered and discussion at the meetings, the Trustees further determined that fees were either shown to be below the peer average in the comparative fee analysis, or that there was a reasonable basis for the fee level. The Trustees also considered the effects of SIMC’s and its affiliates’ voluntary waivers of management and other fees to prevent total Fund operating expenses from exceeding certain amounts and concluded that SIMC, through waivers, has maintained the Funds’ net operating expenses at competitive levels for its distribution channels. In determining the appropriateness of fees, the Board also took into consideration the impact of fees incurred indirectly by the Funds as a result of investments into underlying funds, including funds from which SIMC or its affiliates earn fees. The Board also took into consideration compensation earned from the Funds by SIMC or its affiliates for non-advisory services, such as administration, transfer agency, shareholder services or brokerage, and considered whether SIMC and its affiliates may have realized other benefits from their relationship with the Funds, such as any research and brokerage services received under soft dollar arrangements. When considering fees paid to Sub-Advisers, the Board took into account the fact that the Sub-Advisers are compensated by SIMC and not by the Funds directly, and that such compensation with respect to any unaffiliated Sub-Adviser reflects an arms-length negotiation between the Sub-Adviser and SIMC. Following evaluation, the Board concluded that, within the context of its full deliberations, the expenses of the Funds are reasonable and supported the approval or renewal of the Investment Advisory Agreements. The Board also considered whether the Sub-Advisers and their affiliates may have realized other benefits from their relationship with the Funds, such as any research and brokerage services received under soft dollar arrangements.

Profitability. With regard to profitability, the Trustees considered compensation flowing to SIMC and the Sub-Advisers and their affiliates, directly or indirectly. The Trustees considered whether the levels of compensation and profitability were reasonable. As with the fee levels, when considering the profitability of the Sub-Advisers, the Board took into account the fact that compensation with respect to any unaffiliated Sub-Adviser reflects an arms-length negotiation between the Sub-Adviser and SIMC. In connection with the approval or renewal of each Sub-Advisory Agreement, the Board also took into consideration the impact that the fees paid to the Sub-Adviser have on SIMC’s advisory fee margin and profitability. Based on this evaluation, the Board concluded that, within the context of its full deliberations, the profitability of each of SIMC and the Sub-Advisers is reasonable and supported the approval or renewal of the Investment Advisory Agreements.

Economies of Scale. With respect to the Advisory Agreement, the Trustees considered whether any economies of scale were being realized by SIMC and its affiliates and, if so, whether the benefits of such economies of scale 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. The Trustees recognized that economies of scale are difficult to identify and quantify and are rarely identifiable on a fund-by-fund basis. Based on this evaluation, the Board determined that the fees were reasonable in light of the information that was provided by SIMC with respect to economies of scale.

Based on the Trustees’ deliberation and their evaluation of the information described above, the Board, including all of the Independent Trustees, with the assistance of Fund counsel and Independent Trustees’ counsel, unanimously approved the approval or renewal, as applicable, 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 its deliberations, the Board did not identify any particular factor (or conclusion with respect thereto) or single piece of information that was all-important, controlling or determinative of its decision, but considered all of the factors together, and each Trustee may have attributed different weights to the various factors (and conclusions with respect thereto) and information.
