The State Street Small/Mid Cap Equity Index Portfolio (the Small/Mid Cap Equity Index Portfolio ? or the Portfolio) seeks to provide investment results that, before expenses, correspond generally to the total return of an index that tracks the performance of mid-to small- capitalization exchange traded U.S. equity securities.
The fund tracks the Russell Small Cap Completeness Index, which comprises Russell 3000 companies excluding S&P 500 constituents, using a passive indexing approach. Under various circumstances the fund may purchase a sample of index stocks rather than all constituents, which can cause its returns to diverge from the index. The fund may use futures, options, or swaps on the index in lieu of direct stock ownership.
