Important Risk Disclosure

Equity securities may fluctuate in value and can decline significantly in response to the activities of individual companies and general market and economic conditions.

Returns on investments in stocks of large U.S. companies could trail the returns on investments in stocks of smaller and mid-sized companies.

Passively managed funds invest by sampling the index, holding a range of securities that, in the aggregate, approximates the full Index in terms of key risk factors and other characteristics. This may cause the fund to experience tracking errors relative to performance of the index.

The State Street S&P 500 Index Fund – Institutional Shares (the “Mutual Fund Share Class”) is a mutual fund share class of the State Street® SPDR® Portfolio S&P 500® ETF (the “Fund”). The Fund also offers the State Street® SPDR® Portfolio S&P 500® ETF – ETF Class Shares (the “ETF Share Class”), an exchange-traded fund share class of the Fund. Shares of the ETF Share Class are listed and traded on a national securities exchange and are generally bought and sold at market-determined prices.

The Fund is classified as “diversified” under the Investment Company Act of 1940, as amended (the “1940 Act”); however, the Fund may become “non-diversified,” as defined under the 1940 Act, solely as a result of tracking the Index (e.g., changes in weightings of one or more component securities). When the Fund is non-diversified, it may invest a relatively high percentage of its assets in a limited number of issuers.
