The Fund is an actively-managed exchange-traded fund (ETF). The Fund attempts to achieve its investment objective by investing at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities of large-capitalization companies. The Fund defines large-capitalization companies as those whose market capitalization, at the time of purchase, are consistent with the market capitalizations of companies in the Russell 1000 Growth Index. As of June 30, 2023, the market capitalization of companies in the Russell 1000 Growth Index ranged from approximately $1.345 billion to $2.982 trillion. The Fund may invest any portion of the remaining 20% of its net assets from time to time in equity securities of small-capitalization and mid-capitalization companies.
