State Street 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 an index that tracks the performance of mid-capitalization exchange traded U.S. equity securities. In seeking to track the performance of the S&P MidCap 400 Index (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. The Index is designed to measure the performance of the mid-capitalization segment of the U.S. equity market. The selection universe for the Index includes all U.S. common equities listed on the NYSE, NYSE Arca, NYSE American, NASDAQ Global Select Market, NASDAQ Global Market, NASDAQ Capital Market, Cboe BZX, Cboe BYX, Cboe EDGA, or Cboe EDGX with unadjusted market capitalizations between $8 billion and $22.7 billion and float-adjusted market capitalizations of at least $4 billion at the time of inclusion. These capitalization ranges may be revised by the Index Provider (as defined below) at any time.
