An estimate: each fund’s assets today × its return over the window, added up for the issuer. A loss is never counted as more than what is invested in the fund today.

What a typical $100 invested with them pays each year, weighted by assets.

The share of their funds that were up over the window, out of the funds old enough to have a full record.

Each bar is one fund

The middle fund’s return: half their funds did better, half did worse. One wild fund can’t drag it around.
