Fund Description: SPDR Portfolio S&P 400 Mid Cap ETF, formerly SPDR Portfolio Mid Cap ETF, formerly SPDR S&P 1000 ETF, formerly SPDR Russell Small Cap Completeness ETF, formerly SPDR DJ Wilshire Mid Cap ETF is an exchange-traded index fund or Index ETF which is a separate investment portfolio of the SPDR Series Trust, an open-end investment management company. INVESTMENT OBJECTIVE: The SPDR Portfolio S&P 400 Mid Cap ETF seeks to provide investment results that, before fees and expenses, correspond generally to the total return performance of the S&P MidCap 400 Index, formerly S&P 1000 Index, formerly Russell Small Cap Completeness Index. INDEX DESCRIPTION: The S&P MidCap 400 Index provides investors with a benchmark for mid-sized companies. The index, which is distinct from the large-cap S&P 500, measures the performance of mid-sized companies, reflecting the distinctive risk and return characteristics of this market segment. FUND STRATEGY: Under normal market conditions, the Fund generally invests substantially all, but at least 80%, of its total assets in the securities comprising the Index. In seeking to track the performance of the Index the Fund employs a sampling strategy, which means that the Fund is not required to purchase all of the securities represented in the Index. Instead, the Fund may purchase a subset of the securities in the Index in an effort to hold a portfolio of securities with generally the same risk and return characteristics of the Index. The quantity of holdings in the Fund will be based on a number of factors, including asset size of the Fund. The Fund may invest in equity securities that are not included in the Index, cash and cash equivalents or money market instruments, such as repurchase agreements and money market funds FUND MANAGEMENT: SSgA Funds Management, Inc. (SSgA FM) serves as the investment adviser to the Fund.
