You can build this cheaper yourself
Defined-outcome funds cap your gains (often 8% to 20%) in exchange for cushioning losses by 9% to 30%, priced with options. The fee runs about 0.70% or more, against 0.03% to 0.10% for a plain index fund. For most investors, a simple stock-and-bond mix gives similar protection for far less.
