Recent volatility in financial markets highlights the need for prudent investment decisions if 401(k) plans are to provide an adequate source of retirement income. While plan sponsors and participants may receive help in assessing their investment choices, concerns have been raised about the impartiality of the advice provided. This book examines improved regulation of 401(k) sponsors to better protect participants from conflicts of interest; increased educational outreach and broader oversight of 401(k) plans to reduce plan fees; and investigation into investment options and practices that could restrict withdrawals.
