As of the end of 2003, a third of investors under the FERS system and a quarter of those under the CSRS system had all their money invested in the government securities (G) fund, the most conservative of Thrift Savings Plan investments. In contrast, at the end of 2000, just a tenth of investors in either system were totally in the G fund. As of the end of 2003, the G fund held 41 percent of money on investment and the common stock (C) fund 44 percent, compared with 33 and 63 percent, respectively, at year-end 2000.
