Meanwhile, the TSP continues to explore adding one or two new funds that would combine existing investment options on an automatically adjusted basis. One type of such fund is called the “lifestyle” fund, in which investors choose how aggressive they want to be and the investments are adjusted as returns fluctuate in order to keep that investment posture. Another, called the “life cycle” fund, employs the same principle but also makes the investment mix more conservative over time as the individual approaches retirement. The TSP is considering how one or both of such funds would be structured and would have to issue a contract to a provider; any new fund or funds likely would not be available at least until next year.
