Security Valuation

The Funds utilize various methods to measure the fair value of most of its investments on a recurring basis. U.S. generally accepted accounting principles (“U.S. GAAP”) establishes a framework for measuring fair value and providing related disclosures. Broadly, the framework requires fair value to be determined based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. In the absence of active markets for the identical assets or liabilities, such measurements involve developing assumptions based on market observable data and, in the absence of such data, internal information that is consistent with what market participants would use in a hypothetical transaction that occurs at the measurement date. It also establishes a three-level valuation hierarchy based upon observable and non-observable inputs.

Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our market assumptions. Preference is given to observable inputs. These two types of inputs create the following fair value hierarchy:

• Level 1 — Quoted prices for identical investments in active markets.

• Level 2 — Quoted prices for similar investments in active markets; quoted prices for identical or similar investments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.

• Level 3 — Significant inputs to the valuation model are unobservable.

Policies and procedures are maintained to value investments using the best and most relevant data available. In addition, pricing vendors are utilized to assist in valuing investments. SSGA Funds Management, Inc. (“SSGA FM”) performs periodic reviews of the methodologies used by independent pricing services including price validation of individual securities.

Futures Contracts

Certain Funds may enter into futures contracts to meet the Funds’ objectives. A futures contract is a standardized, exchange-traded agreement to buy or sell a financial instrument at a set price on a future date. Upon entering into a futures contract, a Fund is required to deposit with the broker, cash or securities in an amount equal to the minimum initial margin requirements of the clearing house. Subsequent payments are made or received by a Fund equal to the daily change in the contract value, accumulated, exchange rates, and or other transactional fees. The accumulation of those payments are recorded as variation margin receivable or payable with a corresponding offset to unrealized gains or losses. A Fund recognizes a realized gain or loss when the contract is closed.

Losses may arise if the value of a futures contract decreases due to unfavorable changes in the market rates or values of the underlying instrument during the term of the contract or if the counterparty does not perform under the contract. The use of futures contracts also involves the risk that the movements in the price of the futures contracts do not correlate the movement of the assets underlying such contracts.

For the period ended June 30, 2020 the following Funds entered into futures contracts for strategies listed below:

Fund	Strategies
State Street Institutional U.S. Equity Fund	Equitization of Cash
State Street Institutional Premier Growth Equity Fund	Equitization of Cash
State Street Institutional Small-Cap Equity Fund	Equitization of Cash
State Street Institutional International Equity Fund	Equitization of Cash

Credit Default Swaps

During the period ended June 30, 2020, the State Street Active Core Bond Fund engaged in credit default swaps to manage credit risk. When the Fund is the buyer in a credit default swap contract, the Fund is entitled to receive the par (or other agreed upon) value (full notional value) of a referenced debt obligation (or basket of debt obligations) from the counterparty (or central clearing party (“CCP”) in the case of a centrally cleared swap) to the contract if a credit event by a third party, such as a U.S. or foreign corporate issuer or sovereign issuer, on the debt obligation occurs. In

State Street Institutional Funds

Notes to Schedule of Investments June 30, 2020 (Unaudited)

return, the Fund pays the counterparty a periodic stream of payments over the term of the contract provided that no credit event has occurred. If no credit event occurs, the Fund loses its investment and recovers nothing. However, if a credit event occurs, the Fund receives full notional value for a referenced debt obligation that may have little or no value. When the Fund is the seller of a credit default swap, it receives a fixed rate of income throughout the term of the contract, provided there is no credit event. If a credit event occurs, the Fund is obligated to pay the notional amount of the swap and in certain instances take delivery of securities of the reference entity upon the occurrence of a credit event, as defined under the terms of that particular swap agreement. Credit events are contract specific but may include bankruptcy, failure to pay, restructuring, obligation acceleration and repudiation/moratorium. If the Fund is a seller of protection and a credit event occurs, the maximum potential amount of future payments that the Fund could be required to make would be an amount equal to the notional amount of the agreement. This potential amount would be partially offset by any recovery value of the respective referenced obligation, or net amount received from the settlement of a buy protection credit default swap agreement entered into by the Fund for the same referenced obligation. As the seller, the Fund may create economic leverage to its portfolio because, in addition to its total net assets, the Fund is subject to investment exposure on the notional amount of the swap. The interest fee paid or received on the swap, which is based on a specified interest rate on a fixed notional amount, is accrued daily as a component of unrealized appreciation (depreciation) and is recorded as realized gain upon receipt or realized loss upon payment. The Fund also records an increase or decrease to unrealized appreciation (depreciation) in an amount equal to the daily valuation. For centrally cleared swaps, the daily change in valuation is recorded as a receivable or payable for variation margin and settled in cash with the CCP daily. All upfront payments, if any, are amortized over the life of the swap as realized gains or losses. Those upfront payments that are paid or received, typically for non-centrally cleared swaps, are recorded as other assets or other liabilities, respectively, net of amortization. For financial reporting purposes, unamortized upfront payments, if any, are netted with unrealized appreciation or depreciation on swaps to determine the market value of swaps. The Fund segregates assets in the form of cash or liquid securities in an amount equal to the notional amount of the credit default swaps of which it is the seller. The Fund segregates assets in the form of cash or liquid securities in an amount equal to any unrealized depreciation of the credit default swaps of which it is the buyer, marked to market on a daily basis. Credit default swaps involve greater risks than if the Fund had invested in the referenced debt obligation directly. If the Fund is a buyer of a credit default swap and no credit event occurs, the Fund will not earn any return on its investment. If the Fund is a seller of a credit default swap, the Fund’s risk of loss may be the entire notional amount of the swap. Swaps may also subject the Fund to the risk that the counterparty to the transaction may not fulfill its obligation. In the case of centrally cleared swaps, counterparty risk is minimal due to protections provided by the CCP.

Interest Rate Swaps

Interest rate swaps involve the exchange by a Fund with another party of their respective commitments to pay or receive interest, such as an exchange of fixed rate payments for floating rate payments.

During the period ended June 30, 2020, the State Street Active Core Bond Fund entered into interest rate swaps in order to manage interest rate risk.

Delayed Delivery Transactions and When-Issued Securities

During the period, the State Street Active Core Bond Fund transacted in securities on a delayed delivery or when-issued basis. Payment and delivery may take place after the customary settlement period for that security. The price of the underlying securities and the date when the securities will be delivered and paid for are fixed at the time the transaction is negotiated. The securities purchased on a delayed delivery or whenissued basis are identified as such in the Fund’s Schedule of Investments. The Fund may receive compensation for interest forgone in the purchase of a delayed delivery or when-issued security. With respect to such purchase commitments, the Fund identifies securities as segregated in its records with a value at least equal to the amount of the commitment. Losses may arise due to changes in the value of the underlying securities or if the counterparty does not perform under the contract’s terms, or if the issuer does not issue the securities due to political, economic or other factors.

To-Be-Announced Transactions

The State Street Active Core Bond Fund may seek to obtain exposure to U.S. agency mortgage pass-through securities through the use of “to-be-announced” or “TBA transactions.” “TBA” refers to a commonly used mechanism for the forward settlement of U.S. agency mortgage pass-through securities. In a TBA transaction, the buyer and seller decide on general trade parameters, such as agency, settlement date, coupon, and price.

The Fund may use TBA transactions to “roll over” such agreements prior to the settlement date. This type of TBA transaction is sometimes known as a “TBA roll.” In a TBA roll a Fund generally will sell the obligation to purchase the pools stipulated in the TBA agreement prior to the settlement date and will enter into a new TBA agreement for future delivery of pools of mortgage pass-through securities. A fund may also enter into TBA agreements and settle such transactions on the stipulated settlement date by accepting actual receipt or delivery of the pools of mortgage pass-through securities.

State Street Institutional Funds

Notes to Schedule of Investments June 30, 2020 (Unaudited)

Default by or bankruptcy of a counterparty to a TBA transaction would expose the Fund to possible loss because of adverse market action, expenses or delays in connection with the purchase or sale of the pools of mortgage pass-through securities specified in the TBA transaction. To minimize this risk, the Fund will enter into TBA transactions only with established counterparties. The Fund’s use of “TBA rolls” may impact portfolio turnover, transaction costs and capital gain distributions to shareholders.
