Maximize Americans' Retirement Security Act

This bill requires retirement plan managers (fiduciaries) to primarily consider financial factors like risk and return when selecting investments for employee benefit plans, such as 401(k)s. It allows using non-financial factors (like environmental or social concerns) only if financial factors are insufficient to choose between options, and then mandates detailed documentation explaining why financial factors weren't decisive and how the non-financial choice still serves participants' retirement interests. The rule applies to investments made 60 days after the bill becomes law. It directly affects plan managers overseeing retirement savings, not individual investors.
