This document is about the testimony of Jack VanDerhei from the Employee Benefit Research Institute (EBRI), presenting research on the optimal percentage of 401(k) balances that should be used to purchase a deferred income annuity in order to maximize the probability of a successful retirement, as measured by EBRI's Retirement Readiness Ratings. The research provides insights on how this varies based on factors like age, income level, and life expectancy.
