What Are the Core TSP Funds?

The Thrift Savings Plan offers five individual funds in which to invest:

G Fund

The G Fund is the Government Securities Investment Fund. The TSP states that the fund’s objective is to “ensure preservation of capital and generate returns above those of short-term U.S. Treasury securities.”

F Fund

The F Fund is the Fixed Income Index Investment Fund. It invests in bonds which track the performance of the Bloomberg U.S. Aggregate Bond Index. This index s a broad-based fixed-income index representing intermediate term U.S. investment grade bonds.

C Fund

The C Fund tracks the performance of the S&P 500 index. This is a stock market index tracking the performance of 500 of the largest companies in the United States and is generally considered a standard for measuring overall stock market performance.

S Fund

The S Fund is the Small cap stock Index investment fund. It tracks the performance of the Dow Jones U.S. Completion Total Stock Market Index. This index is made up of small and medium sized companies.

I Fund

The I Fund is the International Stock Index Investment Fund. It tracks the MSCI EAFE (Europe, Australasia, Far East) Index. The I Fund is the international investment option for the TSP as the companies in this index are primarily foreign (non-U.S.) companies. The MSCI EAFE Index is designed to represent the performance of large and mid-cap securities across 21 developed markets, including countries in Europe, Australasia and the Far East, excluding the U.S. and Canada.

What are the TSP L Funds?

The Thrift Savings Plan also offers 10 Lifecycle (L) Funds in which to invest. These funds are a mix of the five core TSP funds (G, F, C, S, and I). They are designed to let you invest your entire portfolio in a single L Fund and get the best expected return for the amount of expected risk that is appropriate for you.

The target allocation of the L Funds changes automatically over time based on your projected retirement age, gradually shifting from more aggressive to more conservative as you approach your projected retirement date. The name of each fund indicates one’s projected retirement date. Once an L Fund reaches its target date, it is automatically rolled into the L Income Fund. For example, in 2055, the L 2055 Fund will be rolled into the L Income Fund.
