The fund invests at least 80% of its total assets (exclusive of collateral held from securities lending) in the component securities of the index. The index uses an objective, rules-based methodology to measure the performance of an equal weight portfolio of approximately 100 large- and mid-capitalization U.S. companies with a high percentage of foreign sales and high free cash flow growth. Free cash flow is a company's cash flow from operations minus its capital expenditures.
