INDEX DESCRIPTION: The S&P GSTI Multimedia Networking Index is an equity benchmark for U.S. traded multimedia networking stocks. The Index includes companies that are producers of telecom equipment, data networking and wireless equipment.

The weight of a particular stock in each Sector Index is capped at a cap level determined on a sector-by-sector basis. The S&P Equity Industry Index Committee maintains the S&P GSSI indices. FUND STRATEGY: The Fund uses a Representative Sampling strategy to try to track the Index. The Fund will concentrate its investments in a particular industry or group of industries to approximately the same extent the Index is so concentrated. Because the Index will always be concentrated in the multimedia networking industry, which comprises 100% of its market capitalization, the Fund will always be concentrated in the multimedia networking industry.
