TSP investment choices including the following funds:
- Government Securities Investment Fund (G Fund), special Treasury issues with an average maturity date of about 14 years;
- Common Stock Index Fund (C Fund), which tracks the Standard & Poor’s 500 index of large U.S. stocks;
- Fixed Income Index Investment Fund (F Fund), a combination of corporate and government bonds;
- Small Capitalization Index Investment Fund (S Fund) tracking the Wilshire 4500;
- International Stock Index Investment Fund (I Fund), tracking the Barclays EAFE index; and
- Lifecycle Funds (L Funds), in which investors pick from one of the available target withdrawal dates (2020, 2030, 2040 or 2050) or an “income fund” for those already withdrawing their accounts or close to that point.
Money is allocated among the other TSP funds according to a pre-set formula balancing potential risk and return, with automatic adjustments to keep the desired ratios and also, in the target date funds, to make the investment mix more conservative over time as the projected withdrawal date approaches.
When investing in the TSP, be sure to make sure you balance both risk and reward. You also should be sure to take into account the risk and reward potential of any other investments you have.
