Number: RS20607 Title: Social Security: Trust Fund Investment Practices Authors: Dawn Nuschler, Domestic Social Policy Division Abstract: The Social Security Act has always required that surplus Social Security income (i.e., income in excess of the program's outgo) be invested in U.S. government securities (or U.S. government-backed securities). Over the past decade or so, increasing attention has been focused on whether to change this practice in order to increase the program's revenue. This report explains current trust fund investment practices and briefly describes the issues involved in changing how the trust funds are invested. Pages: 3 Date: May 29, 2008
