The Innovator International Developed Power Buffer ETF (IAUG) is designed to give investors exposure to the performance of the iShares MSCI EAFE ETF (EFA). It aims to mirror EFA's returns, albeit with a predefined maximum gain or "cap" over a specific period. A key feature of IAUG is its ability to shield investors from the initial 15% of losses incurred during that same outcome period. While the ETF can be held for an extended duration, its buffer and cap characteristics are refreshed and reset approximately once a year at the conclusion of each outcome period.
