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

November 30, 2019

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 27 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, World Select Equity, 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. are wholly-owned subsidiaries of the Dynamic Asset Allocation and Multi-Asset Real Return Funds (the “Subsidiaries”) 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 Summary Schedule of Investments, Consolidated Schedule of Investments, Consolidated Statements of Assets and Liabilities, Consolidated Statements of Operations, Consolidated Statements of Changes in Net Assets, Consolidated Statement of Cash Flows 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 — 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 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. 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, the Funds will value the securities using a bid price from at least one independent broker. If such prices are not readily available or cannot be valued using the methodologies described above, the Funds will value the security using the Funds’ Fair Value Pricing Policies and Procedures (“Fair Value Procedures”), as described below.

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 Funds’ Fair Value Procedures 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

  324   SEI Institutional Investments Trust / Semi-Annual Report / November 30, 2019

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. SEI Investments Management Corporation (“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 or a Sub-Adviser, as applicable, 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 Fair Value Pricing Committee (the “Committee”) if it receives such notification from SIMC or 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 Funds’ Fair Value Procedures provide that any change in a primary pricing agent or a pricing methodology requires prior approval by the Board of Trustees (“Board”) or its designated sub-committee. 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 the Fund’s existing pricing agent or pricing methodology, approval 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 the Fair Value Procedures established by the Board. The Funds’ Fair Value Procedures are implemented through the Committee designated by the Board. The Committee is currently composed of two members of the Board, as well as representatives from SIMC and its affiliates. Some of the more common reasons that may necessitate that a security be valued using Fair Value Procedures include: (i) the security’s trading has been halted or suspended, (ii) the security has been delisted 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, or (iv) the security’s primary pricing source is not able or willing to provide a price. When a security is valued in accordance with the Fair Value Procedures, the Committee will determine the value after taking into consideration relevant information reasonably available to the Committee. Examples of factors the Committee may consider include: (i) the facts giving rise to the need to fair value, (ii) the last trade price, (iii) the performance of the market or the issuer’s industry, (iv) the liquidity of the security, (v) the size of the holding in a Fund, or (vi) any other appropriate information.

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

  SEI Institutional Investments Trust / Semi-Annual Report / November 30, 2019   325

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

November 30, 2019

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 the Fund calculates NAV. A Fund may invest in securities that are primarily listed on foreign exchanges that trade on weekends or other days when the Fund does not price its shares. As a result, the NAV of the 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.

The U.S. Managed Volatility, Global Managed Volatility, World Equity Ex-US, Screened World Equity Ex-US, World Select Equity, Emerging Markets Equity, Opportunistic Income, Core Fixed Income, High Yield Bond, Emerging Markets Debt and Multi-Asset Real Return Funds that hold international securities also 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.)

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

  326   SEI Institutional Investments Trust / Semi-Annual Report / November 30, 2019

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 period ended November 30, 2019 maximized the use of observable inputs and minimized the use of unobservable inputs. For details of the investment classification, reference the Summary Schedules of Investments/Schedules of Investments.

For the period ended November 30, 2019, there have been no significant changes to the Trust’s fair valuation methodologies.

Security Transactions and Investment Income — Security transactions are recorded on the trade date. 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 Statement 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. 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 Statement of Assets and Liabilities/ Consolidated Statement of Assets and Liabilities and Consolidated Statement of Cash Flows. These amounts, at times, may exceed United States federally insured

limits. Amounts swept are available on the next business day.

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.

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 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.

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

  SEI Institutional Investments Trust / Semi-Annual Report / November 30, 2019   327

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

November 30, 2019

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, Summary Schedule of Investments, Consolidated Schedule of Investments or Consolidated Summary Schedule of Investments for details regarding open forward foreign currency contracts as of November 30, 2019, 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 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

  328   SEI Institutional Investments Trust / Semi-Annual Report / November 30, 2019

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, Summary Schedule of Investments, Consolidated Summary Schedule of Investments or Consolidated Schedule of Investments for details regarding open futures contracts as of November 30, 2019, 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.

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 World Select Equity, Core Fixed Income, Dynamic Asset Allocation and Multi-Asset Real Return Funds had options/swaption contracts as of November 30, 2019, as disclosed in the Funds’ Schedule of Investments or Consolidated Summary Schedule of Investments.

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

Finally, the risk exists that losses on written options could exceed amounts disclosed on the Statements of Assets and Liabilities. Refer to each Fund’s Schedule of Investments or Consolidated Summary Schedule of Investments for details regarding open option/swaption contracts as of November 30, 2019, 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

  SEI Institutional Investments Trust / Semi-Annual Report / November 30, 2019   329

November 30, 2019

the short position is closed out. A gain, limited to the price at which a Fund sold the security short, or a loss, unlimited in size, will be recognized upon the close of a short sale.

Until a Fund closes its short position or replaces the borrowed security, the Fund will: (i) earmark on the books of the Fund or place in a segregated account cash or liquid securities at such a level that the amount earmarked or deposited in the segregated account plus the amount deposited with the broker as collateral will equal the current value of the security sold short; or (ii) otherwise “cover” the Fund’s short position as required by the 1940 Act. Refer to each Fund’s Schedule of Investments, Summary Schedule of Investments, Consolidated Summary Schedule of Investments or Consolidated Schedule of Investments for details regarding securities sold short as of November 30, 2019, 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 credit default 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 LIBOR or some other form of indices on the notional amount. Interest rate swaps involve the exchange by a Fund with another party of their respective commitments to pay or receive interest (e.g., an exchange of floating rate payments for fixed rate payments) with respect to a notional amount of principal to manage 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.

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

  330   SEI Institutional Investments Trust / Semi-Annual Report / November 30, 2019

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, Summary Schedule of Investments, Consolidated Summary Schedule of Investments or Consolidated Schedule of Investments for details regarding open swap agreements as of November 30, 2019, 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.

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

  SEI Institutional Investments Trust / Semi-Annual Report / November 30, 2019   331

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

November 30, 2019

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. The interest rate indicated in the Fund’s Schedule of Investments is the rate in effect at November 30, 2019. 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 disclosed consent fees and amendment income in the Statement of Operations as “Interest income”. As of November 30, 2019, the Funds had no unfunded commitments in loan participations.

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 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, World Select Equity, 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.

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

Restricted Securities — As of November 30, 2019, the following Fund owned private placement investments that were purchased through private offerings or acquired through initial public offerings and cannot be sold without prior registration under the Securities Act of 1933 or pursuant to an exemption therefrom. In addition, this Fund has 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 private placement investments. The acquisition dates of these investments, the enforceable right to acquire these private placement investments, along with the cost and values at November 30, 2019, were as follows:

Investments in Real Estate Investment Trusts (“REITs”) — With respect to the Funds, with the exception of the World Equity Ex-US, Screened World Equity Ex-US and Real Return Funds, dividend income is recorded based on the income included in distributions received from the REIT investments using published REIT reclassifications including some management estimates when actual amounts are not available. Distributions received in excess of this estimated amount are recorded as a reduction of the cost of investments or reclassified to capital gains. The actual amounts of income, return of capital, and capital gains are only determined by each REIT after its fiscal year-end, and may differ from the estimated amounts.

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

November 30, 2019

a specified valuation method, are used to calculate the settlement value.

As of November 30, 2019, the High Yield Bond, Emerging Markets Debt and Multi-Asset Real Return Funds are the buyers (“receiving protection”) on a total notional amount of $28.5 million, $27.4 million and $20.0 million, respectively. Additionally, the Core Fixed Income, High Yield Bond, Emerging Markets Debt and Multi-Asset Real Return Funds are the sellers (“providing protection”) on a total notional amount of $134.8 million, $17.2 million, $6.2 million and $21.6 million, respectively. The notional amounts of the swaps are not recorded in the financial statements; however the notional amounts approximate the maximum potential amount of future payments that the Fund could be required to make if the Fund was the seller of protection and a credit event were to occur. Those credit default swaps (“CDS”) for which the Fund is providing protection at balance sheet date are summarized as follows:

Core Fixed Income Fund
Written Credit Derivative Contracts			Single Name CDS				CDS Index
Reference Asset	Corp US$		Sovereign US$		ABS US$		Corp US$		Total
Fair value of written credit derivatives	$	–	$	–	$	–	$	3,250,784	$	3,250,784

(1) Potential recoveries would include purchased credit derivatives to the extent they offset written credit derivatives which have an identical underlying, or a netting arrangement or credit support annex with the counterparty. There may be other potential recoveries from recourse provisions where agreements cover multiple derivative arrangements but those amounts have not been included.

* 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.

* 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.

^†  Represents cost.

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.

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.

5. BASIS FOR CONSOLIDATION FOR THE DYNAMIC ASSET ALLOCATION AND MULTI-ASSET REAL RETURN FUNDS

The Consolidated Summary Schedule of Investments, Consolidated Schedule of Investments, Consolidated Statements of Assets and Liabilities, Consolidated Statements of Operations, Consolidated Statements of Changes in Net Assets, Consolidated Statement of Cash Flows, and the Consolidated Financial Highlights of the Dynamic Asset Allocation and Multi-Asset Real Return Funds include the accounts of their respective Subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation for the Funds. The Subsidiaries have a fiscal year end of May 31 for financial statement consolidation purposes and a nonconforming tax year end of April 30.

The Subsidiaries are classified as controlled foreign corporations under the Internal Revenue Code of 1986 (“IRC”). The Subsidiaries taxable income is included in the calculation of the Funds’ taxable income. Net losses of the Subsidiaries are not deductible by the Funds

either in the current period or carried forward to future periods.

The Dynamic Asset Allocation and Multi-Asset Real Return Funds may invest up to 25% of their total assets in their respective Subsidiary.

A summary of the Funds’ investments in the Subsidiaries are as follows:

	Inception Date of Subsidiary		Subsidiary     Net Assets at     November 30,     2019     ($ Thousands)		% of Total     Net Assets at     November  30,     2019

6. INVESTMENT ADVISORY, ADMINISTRATION AND DISTRIBUTION AGREEMENTS, INVESTMENT SUBADVISORY AGREEMENTS AND OTHER TRANSACTIONS WITH AFFILIATES

Investment Advisory, Administration and Distribution Agreements — 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 period ended November 30, 2019, the Administrator has voluntarily agreed to waive all of its fee. The Funds’ Administrator may discontinue all or part of these voluntary waiver at any time.

SIMC serves as investment adviser (the “Adviser”) to each Fund. In connection with serving as Adviser, SIMC is entitled to a fee that is calculated daily and paid monthly, based on the average daily net assets of each Fund. SIMC plans to voluntarily waive a portion of its fees in order to keep investment advisory fees at a specified level. The Funds’ Adviser may discontinue all or part of these voluntary waivers at any time. Accordingly, the advisory fee and voluntary expense limitations for each Fund are as follows:

* Affiliated

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.

Such commissions for the period ended November 30, 2019, were as follows ($ Thousands):

Small Cap II Fund	$1
U.S. Equity Factor Allocation Fund	56
World Equity Ex-US Fund	26
World Select Equity Fund	15

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.

  SEI Institutional Investments Trust / Semi-Annual Report / November 30, 2019   347

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

November 30, 2019

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, Global Managed Volatility and Intermediate Duration Credit Funds. For this service, LSV Asset Management is entitled to receive a fee from SIMC. Such fees for the period ended November 30, 2019, were as follows ($ Thousands):

Large Cap Fund	$196
Small Cap Fund	187
Small/Mid Cap Equity Fund	631
Global Managed Volatility Fund	1,623
U.S. Managed Volatility Fund	906
World Select Equity Fund	79

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 period ended November 30, 2019, 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. Additionally, the Funds may invest the cash collateral from the securities lending program in the SEI Liquidity Fund, L.P.

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.

At November 30, 2019, the Trust had no outstanding borrowings.

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

  350   SEI Institutional Investments Trust / Semi-Annual Report / November 30, 2019

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 each requested private letter rulings from the Internal Revenue Service (“IRS”) concluding that the income generated from their investment in their respective Subsidiaries, each of which invests in commodity-linked derivatives, will be “qualifying income” for regulated investment company (“RIC”) qualification purposes, regardless of whether actual distributions are made to the Funds by the respective Subsidiary.

In July 2011, the IRS suspended the issuance of private letter rulings regarding the investment by RICs into controlled foreign corporations which principally invest in commodities, such as the Subsidiaries, indicating that it was reconsidering its policies surrounding the issuance of these rulings. The Dynamic Asset Allocation and Multi-Asset Real Return Funds have secured an opinion of counsel based on customary representations that actual distributions made to the Funds should be

treated as “qualifying income”. The Treasury released a proposed regulation in October of 2016 stating that income inclusion from a controlled foreign corporation is treated as dividends i.e. qualifying income only to the extent that the Funds received cash distributions from the subsidiary. The distribution requirement is consistent with the Funds’ policy. The Treasury released a final regulation in March 2019 reversing its position on the proposed regulation by removing the cash distribution requirement. As a conservative measure, the Funds will continue to follow their existing distribution policy.

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.

The tax character of dividends and distributions paid during the last two years or periods ended May 31, 2019 were as follows:

		Ordinary Income ($ Thousands)		Long-term Capital Gain ($ Thousands)		Return of Capital ($ Thousands)		Total ($ Thousands)
Large Cap Fund
	2019	$	83,505	$	215,389	$	–	$	298,894

Post-October losses represent losses realized on investment transactions from November 1, 2018 through May 31, 2019 that, in accordance with Federal income tax regulations, the Funds may elect to defer and treat as having arisen in the following fiscal year.

During the year ended May 31, 2019, the Core Fixed Income Fund, Ultra Short Duration Bond Fund, and Real Return Fund utilized capital loss carryforwards to offset capital gains of $114,603 ($ Thousands), $13 ($ Thousands) and $175 ($ Thousands), respectively. The Opportunistic Income Fund had expired capital losses in the amount of $19,071 ($ Thousands) for the year ended May 31, 2019.

Funds are permitted to carry forward capital losses incurred in taxable years beginning after December 22, 2010 for an unlimited period. Additionally, post-enactment capital losses that are carried forward will retain their character as either short-term or long-term capital losses rather than being considered all short-term as under previous law. Losses carried forward under these new provisions are as follows:

	Short-Term Loss ($ Thousands)		Long-Term Loss ($ Thousands)		Total * ($ Thousands)

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.

Management has analyzed the Funds’ tax positions taken on Federal income tax returns for all open tax years and has concluded that as of November 30, 2019, 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.

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, World Select Equity, 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:

  354   SEI Institutional Investments Trust / Semi-Annual Report / November 30, 2019

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.

Collateralized Debt Obligations (CDOs) and Collateralized Loan Obligations (CLOs) Risk — CDOs and CLOs are securities backed by an underlying portfolio of debt and loan obligations, respectively. CDOs and CLOs issue classes or “tranches” that vary in risk and yield and may experience substantial losses due to actual defaults, decrease in market value due to collateral defaults and removal of subordinate tranches, market anticipation of defaults and investor aversion to CDO and CLO securities as a class. The risks of investing in CDOs and CLOs depend largely on the tranche invested in and the type of the underlying debts and loans in the tranche of the CDO or CLO, respectively, in which the Fund invests. CDOs and CLOs also carry risks including, but not limited to, interest rate risk and credit

risk, which are described below. For example, a liquidity crisis in the global credit markets could cause substantial fluctuations in prices for leveraged loans and high-yield debt securities and limited liquidity for such instruments. When the Fund invests in CDOs or CLOs, in addition to directly bearing the expenses associated with its own operations, it may bear a pro rata portion of the CDO’s or CLO’s expenses.

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 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

  SEI Institutional Investments Trust / Semi-Annual Report / November 30, 2019   355

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

November 30, 2019

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 — 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. 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.

Depositary Receipts Risk — Depositary receipts, such as American Depositary Receipts, are certificates evidencing ownership of shares of a foreign issuer that are issued by depositary banks and generally trade on an established market. Depositary receipts 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.

Derivatives Risk — The Fund’s use of futures contracts and swaps is subject to leverage risk, correlation risk, liquidity risk and market risk. Leverage risk and liquidity risk are described below. Many over-the-counter (OTC) derivative instruments will not have liquidity beyond the counterparty to the instrument. Market risk is the risk that the market value of an investment may move up and down, sometimes rapidly and unpredictably. 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 swaps is also subject to credit risk and valuation risk. Credit risk is described above. 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 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. Both U.S. and non-U.S. regulators are in the process of adopting and implementing 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.

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.

Exchange-Traded Notes Risk — The value of an ETN is subject to the credit risk of the issuer. There may not be an active trading market available for some ETNs. Additionally, trading of ETNs may be halted or the ETN may be delisted by the listing exchange.

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. In the case of foreign securities, price fluctuations will reflect international economic and political events, as well as changes in currency valuations relative to the U.S. dollar. In response to these events, the Fund’s value may

  356   SEI Institutional Investments Trust / Semi-Annual Report / November 30, 2019

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 Issuer Risk — The risk that issuers in foreign countries face political and economic events unique to those countries. These events will not necessarily affect the U.S. economy or similar issuer located in the U.S.

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 rise in interest rates will cause a fall in the value of fixed income securities, including U.S. Government securities, in which a Fund invests. 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.

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 — Certain Fund transactions, such as derivatives or reverse repurchase agreements, may give rise to a form of leverage. The use of leverage can amplify the effects of market volatility on the Funds’ share price and make the Funds’ returns more volatile. This is because leverage tends to exaggerate the effect of any increase or decrease in the value of the Funds’ portfolio securities. The use of leverage may also cause the Funds to liquidate portfolio positions when it would

  SEI Institutional Investments Trust / Semi-Annual Report / November 30, 2019   357

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

November 30, 2019

not be advantageous to do so in order to satisfy its obligations.

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.

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

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. 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

  358   SEI Institutional Investments Trust / Semi-Annual Report / November 30, 2019

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 additional capital gains tax liabilities, 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 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 Agreement Risk — Although repurchase agreement transactions must be fully collateralized at all times, they generally create leverage and involve some counterparty risk to the Fund whereby a defaulting counterparty could delay or prevent the Fund’s recovery of collateral.

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 — The 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 or listed on an exchange.

Social Investment Criteria Risk — The Fund’s portfolio is subject to certain social investment criteria. As a result, the Sub-Advisers may 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

  SEI Institutional Investments Trust / Semi-Annual Report / November 30, 2019   359

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

November 30, 2019

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 certain qualifying income tests 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 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.

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.

12. 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

  360   SEI Institutional Investments Trust / Semi-Annual Report / November 30, 2019

risks, including the risk that the Fund may be delayed or prevented from recovering the collateral if the borrower fails to return the securities.

Cash collateral received in connection with securities lending is invested in short-term investments by the lending agent. These investments may include the SEI Liquidity Fund, L.P., and the Fund bears all of the gains and losses on such investment. There is no guarantee that these investments will not lose value.

The following is a summary of securities lending agreements held by certain Funds which would be subject to offset as of November 30, 2019 ($ Thousands):

14. REGULATORY MATTERS

In July 2017, the Financial Conduct Authority, the United Kingdom’s financial regulatory body, announced that after 2021 it will cease its active encouragement of banks to provide the quotations needed to sustain LIBOR. That announcement suggests that LIBOR very likely will cease to be published after that time. Various financial industry groups have begun planning for that transition, whether through marketwide protocols, fallback contractual provisions, bespoke negotiations or amendments or otherwise, but there are obstacles to converting certain securities and transactions to a new benchmark. Transition planning is at an early stage, and neither the effect of the transition process nor its ultimate success can yet be known. The transition process might lead to increased volatility and illiquidity in markets for instruments whose terms currently include LIBOR. It could also lead to a reduction in the value of some LIBOR-based investments and reduce the effectiveness of new hedges placed against existing LIBOR-based investments. While some LIBOR-based instruments may contemplate a scenario where LIBOR is no longer available by providing for an alternative rate-setting methodology and/or increased costs for certain LIBOR-related instruments or financing transactions, not all may have such provisions and there may be significant uncertainty regarding the effectiveness of any such alternative methodologies, resulting in prolonged adverse market conditions for the Fund. Because the usefulness of LIBOR as a benchmark could deteriorate during the transition period, these effects could occur prior to the end of 2021. There also remains uncertainty and risk regarding the willingness and ability of issuers to include enhanced provisions in new and existing contracts or instruments. All of the aforementioned may adversely affect the Fund’s performance or NAV.

On August 17, 2018, the SEC adopted amendments to Regulation S-X. These changes are effective for periods

  SEI Institutional Investments Trust / Semi-Annual Report / November 30, 2019   361

NOTES TO FINANCIAL STATEMENTS / CONSOLIDATED NOTES TO FINANCIAL STATEMENTS (Unaudited) (Concluded)

after November 5, 2018. The updates to Registered Investment Companies were mainly focused on simplifying the presentation of distributable earnings by eliminating the need to present the components of distributable earnings on a book basis in the Statements of Assets and Liabilities/Consolidated Statements of Assets and Liabilities. The update also impacted the presentation of undistributed net investment income and distribution to shareholders on the Statements of Changes in Net Assets/Consolidated Statements of Changes in Net Assets. The amounts presented in the current Statements of Changes in Net Assets/ Consolidated Statements of Changes in Net Assets represent the aggregated total distributions of net investment income and realized capital gains, except for distributions classified as return of capital which are still presented separately.

15. NEW ACCOUNTING PRONOUNCEMENTS

In August 2018, the FASB issued Accounting Standards Update 2018-13, Fair Value Measurement (Topic 820). The new guidance includes additions and modifications to disclosures requirements for fair value measurements. For public entities, the amendments are effective for financial statements issued for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Management elected to early adopt the removal and modifications of certain disclosures and delay the adoption of additional disclosures until the effective date.

16. 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 as of November 30, 2019.

DISCLOSURE OF FUND EXPENSES (Unaudited)

November 30, 2019

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

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

The following examples use the expense ratio and are intended to help you understand the ongoing costs (in dollars) of investing in your fund and to compare these costs with those of other mutual funds. The examples are based on an investment of $1,000 made at the beginning of the period shown and held for the entire period (June 1, 2019 through November 30, 2019).

The table on this page illustrates your fund’s costs in two ways:

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

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

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

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