Principal U.S. Mega-Cap 

USMC seeks long-term capital growth by targeting mega-caps in the US equity market. Mega-cap refers to a company with a market capitalization in the top 50th percentile of the S&P 500. To build the portfolio, the fund utilizes a proprietary, quantitative model. Companies in the S&P 500 with the largest market capitalizations are selected, with low-volatility stocks typically given greater weight in the portfolio. In constructing the model and managing the portfolio, the fund adviser uses insights from multiple sources, including internal research, industry reports, and third-party data. While the portfolio is rebalanced at least annually, the fund adviser has the discretion to make adjustments. Prior to September 30, 2020, the fund name was Principal U.S. Mega-Cap Multi-Factor Index ETF. On June 10, 2022, the fund ceased tracking the NASDAQ US Mega Cap Select Leaders Index and transitioned to an active management strategy.
