Security Valuation

Each Fund’s investments are valued at fair value each day that the New York Stock Exchange (“NYSE”) is open and, for financial reporting purposes,as of the report date should the reporting period end on a day that the NYSE is not open. Fair value is generally defined as the price a fund would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date. By its nature, a fair value price is a good faith estimate of the valuation in a current sale and may not reflect an actual market price. The investments of each Fund are valued pursuant to the policy and procedures developed by the Oversight Committee (the “Committee”) and approved by the Board of Trustees of the Trust (the “Board”). The Committee provides oversight of the valuation of investments for the Funds. The Board has responsibility for determining the fair value of investments.

Valuation techniques used to value each Fund’s investments by major category are as follows:

• Equity investments (including preferred stocks and registered investment companies that are exchange-traded funds) traded on a recognized securities exchange for which market quotations are readily available are valued at the last sale price or official closing price, as applicable, on the primary market or exchange on which they trade. Equity investments traded on a recognized exchange for which there were no sales on that day are valued at the last published sale price or at fair value.

• Investments in registered investment companies (including money market funds) or other unitized pooled investment vehicles that are not traded on an exchange are valued at that day’s published net asset value per share or unit.

• Government and municipal fixed income securities are generally valued using quotations from independent pricing services or brokers. Certain government inflation-indexed securities may require a calculated fair valuation as the cumulative inflation is contained within the price provided by the pricing service or broker. For these securities, the inflation component of the price is “cleaned” from the pricing service or broker price utilizing the published inflation factors in order to ensure proper accrual of income.

• Debt obligations (including short term investments and convertible debt securities) are valued using quotations from independent pricing services or brokers or are generally valued at the last reported evaluated prices.

• Exchange-traded futures contracts are valued at the closing settlement price on the primary market on which they are traded most extensively. Exchange-traded futures contracts traded on a recognized exchange for which there were no sales on that day are valued at the last reported sale price obtained from independent pricing services or brokers or at fair value.

• Options on futures are priced at their last sale price on the principal market on which they are traded on the valuation date. If there were no sales on that day, options on futures are valued at either the last reported sale or official closing price on their primary exchange determined in accordance with the valuation policy and procedures approved by the Board.

• Swap agreements are valued daily based upon prices supplied by Board approved pricing vendors or through brokers. Depending on the product and terms of the transaction, the value of agreements is determined using a series of techniques including valuation models that incorporate a number of market data factors, such as discounted cash flows, yields, curves, trades and values of the underlying reference instruments. In the event SSGA Funds Management, Inc. (“SSGA FM”) is unable to obtain an independent, third–party valuation the agreements will be fair valued.

In the event prices or quotations are not readily available or that the application of these valuation methods results in a price for an investment that is deemed to be not representative of the fair value of such investment, fair value will be determined in good faith by the Committee, in accordance with the valuation policy and procedures approved by the Board.

The Funds value their assets and liabilities at fair value using a fair value hierarchy consisting of three broad levels that prioritize the inputs to valuation techniques giving the highest priority to readily available unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements) when market prices are not readily available or reliable. The categorization of a value determined for an investment within the hierarchy is based upon the pricing transparency of the investment and is not necessarily an indication of the risk associated with investing in it.

The three levels of the fair value hierarchy are as follows:

• Level 1—Unadjusted quoted prices in active markets for an identical asset or liability;

• Level 2—Inputs other than quoted prices included within Level 1 that are observable for the asset or liability either directly or indirectly, including quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not considered to be active, inputs other than quoted prices that are observable for the asset or liability (such as exchange rates, financing terms, interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates) or other market-corroborated inputs; and

• Level 3—Unobservable inputs for the asset or liability, including the Committee’s assumptions used in determining the fair value of investments.

The value of each Fund’s investments according to the fair value hierarchy as of June 30, 2019 is disclosed in each Fund’s respective Schedule of Investments.

Changes in valuation techniques may result in transfers in or out of an assigned level within the fair value hierarchy. Transfers between different levels of the fair value hierarchy are recognized at the end of the reporting period. The Funds had no material transfers between levels for the six-month period ended June 30, 2019.

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 and are recorded as variation margin receivable or payable with a corresponding offset to unrealized gains or losses. The Funds recognize 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, 2019, 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
State Street Active Core Bond Fund	Management of Interest Rate Risk

Credit Default Swaps

During the period ended June 30, 2019, 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 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, 2019, the State Street Active Core Bond Fund entered into interest rate swaps in order to manage exposure to interest rates.

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.

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.
