How Returns Are Calculated:
G Fund—By definition, the G Fund never can have a losing month. All investments in the fund earn interest at a rate equal to the average of market yields on Treasury marketable securities with four or more years to maturity.
G Fund returns are reduced by administrative expenses, which are about 0.06 percent, or $.60 for every $1,000 invested.
C, S, I and F Funds—The C, S, I and F Funds can post gains or losses.
The capital gain or loss consists of these elements:
- the change in the price of the stocks in the equity index funds (C, S and I Funds) or the notes in the U.S. Debt Index Fund (F Fund);
- dividend (C, S and I Funds) or interest (F Fund) income credited to the funds;
- interest on short term investments while contributions are awaiting investment;
- income from lending securities (C, S and I Funds) or notes and bonds (F Fund) on a short-term basis;
- administrative expenses, including management fees paid to Barclays, which are about 0.06 percent, or $.60 for every $1,000 invested in the C and F Funds and about 0.05 percent, or $.50 for every $1,000 invested, in the S and I Funds; and
- trading costs.
In addition, the I Fund fluctuates relative to the U.S. dollar’s value against the currencies of the countries in whose stock markets that fund has investments.
