The Fund seeks to achieve its investment objective by providing investors with US large-cap equity market exposure while attempting to limit downside risk through a laddered portfolio of twelve FT Vest U.S. Equity Deep Buffer ETFs (the Underlying ETFs). The term laddered portfolio refers to the Fund's investment in multiple Underlying ETFs that have target outcome period expiration dates which occur on a rolling, or periodic, basis. See below for a discussion of target outcome periods and their meaning within the strategies of the Underlying ETFs. The rolling or laddered nature of the investments in the Underlying ETFs creates diversification of investment time period compared to the risk of acquiring or disposing of any one Underlying ETF at any one time. This diversification of investment time period is intended to mitigate the risk of failing to benefit from the buffer of a single Underlying ETF due to the timing of investment in such Underlying ETF and the relative price of the reference asset or having limited or no upside potential remaining because of the cap of a single Underlying ETF. The Fund's laddered approach is intended to allow the Fund to continue to benefit from increases in the value of the SPDR S&P 500 ETF Trust (SPY) and to provide a level of downside protection for at least a portion of the Fund's portfolio at any given time. Depending on when the Fund acquires shares of an Underlying ETF, even with a laddered approach, the cap and/or buffer of an Underlying ETF may be exhausted unless the Fund acquires shares at the beginning of a Target Outcome Period (as defined below). The Fund does not typically buy shares at the beginning of the Target Outcome Period. Unlike the Underlying ETFs, the Fund itself does not pursue a target outcome strategy. The buffer is only provided by the Underlying ETFs and the Fund itself does not provide any stated buffer against losses. The Fund will likely not receive the full benefit of the Underlying ETF buffers and could have limited upside potential. The Fund's returns are limited by the caps of the Underlying ETFs.
