Determining the “default” investment for savers who do not make a decision about where to direct their contributions is a weighty decision. The downside of putting the money into investments that carry more risk, and a greater potential for loss, is obvious. But parking the contributions in a “safe” investment with lower risk means participants’ accounts may not grow sufficiently to provide significant income security in retirement. Increasingly, target-date funds (TDFs) have become a popular solution.
