1. Entries shown in red indicate that income insurance is paid.
2. Bond Fund annuities are graded annuities designed to increase over time to help counter inflation. They begin as if they were a 2% annuity and increase annually at the rate of about 3% with a 5% bond fund return. See Appendix C.
3. Stock fund annuities are variable annuities which begin as if they were a 5% annuity and are adjusted each year to reflect actual stock fund performance.
4. Yearly returns during retirement are taken from CREF historical returns for a 20-year period during which the 20-year annual return was 7.7%. See Returns B in Figure 6a.
