Most employer-offered retirement plans have what's called a target date option, broadly diversified investments that offer different "target dates" for investors in different age brackets. These target date funds mostly invest in index funds that are not sustainably invested. If a retirement plan has automatic enrollment, the target date series is usually the default investment option, also known as the Qualified Default Investment Alternative. When you sign up for the plan, your savings are put in a default investment, and most plan participants never switch. Even if plans don't have automatic enrollment, a target date series frequently serves as the de facto default, capturing more assets than any other plan options. For the overall plan scorecard above, we use the 2050 target date as the representative of the fund series.
