The Underlying Index is designed to track the performance of quality large-capitalization companies listed in the United States, as determined by Indxx, LLC ( Indxx ), the index provider of the Underlying Index. Indxx is not affiliated with the Fund or the Funds investment adviser, Virtus Investment Advisers, LLC (the Adviser ). The Underlying Index includes common stock and American depositary receipts ( ADRs ). The 500 largest U.S. securities by market capitalization, as determined by Indxx, are eligible for inclusion in the Underlying Index. Eligible securities are then screened and ranked based on a momentum and quality score. Momentum refers to a securitys tendency to exhibit persistence in its relative performance, and quality refers to companies that exhibit strong fundamentals. The momentum score is calculated based on an issuers last twelve months total return. The quality score is calculated based on the following three quality factors: return on equity (calculated as the issuers net income divided by average shareholder equity); debt to equity (calculated as the issuers total liabilities divided by total shareholder equity); and sales growth rate (calculated as the issuers annualized sales growth rate over the past three years). The 250 securities with the highest calculated momentum score will form the selection universe for the Underlying Index. Each security is then ranked within each of the three quality factors (return on equity, debt to equity, and sales growth rate) and given a composite score based on its cumulative rank. The 125 securities with the lowest composite scores ( i.e. , the highest composite rankings) will form the components of the Underlying Index. Securities within the Underlying Index are equally weighted at each rebalance and reconstitution. The Underlying Index is rebalanced and reconstituted quarterly. The Fund is reconstituted and rebalanced in accordance with the Underlying Index. Under normal market conditions, the Fund will invest not less than 80% of its net assets (plus the amount of any borrowings for investment purposes) in U.S. securities. The Fund considers a security to be a U.S. security if: (i) its issuer is organized under the laws of, or maintains a principal place of business in, the U.S.; (ii) its principal trading market is in the U.S.; or (iii) its issuer, during its most recent fiscal year, derived at least 50% of its revenues or profits from goods produced or sold, investments made, or services performed in the U.S., or has at least 50% of its assets in the U.S. The Fund will not seek to beat the performance of the Underlying Index and will not seek temporary defensive measures when markets decline or appear overvalued. Instead, the Fund uses a passive or indexing investment approach to try to approximate the investment performance of the Underlying Index by investing in a portfolio of securities that generally replicates the Underlying Index; however, there may be times when the Fund does not hold every security in the Underlying Index. The Adviser expects that, over time, the correlation between the Funds performance before fees and expenses and that of the Underlying Index will be 95% or better. A figure of 100% would indicate perfect correlation. The Fund will concentrate its investments ( i.e. , hold more than 25% of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. As of July 31, 2025, the Underlying Index was concentrated in the financials, information technology and industrials sectors. Show less
