The Fund will invest at least 80% of its net assets (including investment borrowing) in the exchange-traded funds (ETFs) that comprise the Index. The Fund, using an indexing investment approach, seeks investment results that generally correspond, before fees and expenses, to the performance of the Index. The Index provider, Refinitiv/Thomson Reuter (Thomson Reuter or the Index Provider), compiles, maintains and calculates the Index. The Index is composed of the shares of twelve Innovator U.S. Equity Power Buffer ETFs (each, an Underlying ETF, and together, the Underlying ETFs). The Fund, in accordance with the Index, will be continuously invested in each of the Underlying ETFs and will rebalance semi-annually by purchasing and selling the Underlying ETFs to equally weight the Underlying ETFs. As further described below, each Underlying ETF seeks to provide a defined outcome based upon the price performance of the S&P 500 Index (S&P 500 Price Index) over the course of an approximately one-year time period (each, an Outcome Period) that begins on the first trading day of the month indicated in the Underlying ETFs name. Each Underlying ETF seeks to provide an upside return that is capped for an applicable Outcome Period (a Cap) and a measure of downside protection from losses for such Outcome Period (i.e., a buffer).
