PRINCIPAL QUALITY ETF

The investment seeks to provide investment results that closely correspond, before expenses, to the performance of the Nasdaq US Price Setters Index. Under normal circumstances, the fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities of companies that compose the index at the time of purchase. The index uses a quantitative model designed to identify equity securities of mid- to large-capitalization companies in the Nasdaq US Large Mid Cap Index (the parent index) that exhibit higher quality, growth potential, and pricing power.
