A retirement fund program managed by computer software requiring an initial fixed investment and producing an ever increasing revenue stream to a group of participant investors organized by life expectancy and grouped into an investment partnership. A financial portfolio is created from the monies invested by each investor and is used to manage high quality securities to generate income for the partnership. Periodically, the surviving members of the partnership are entitled to receive the revenue generated from the portfolio, which statistically will increase as fewer participant investors survive. The partnership can purchase term life insurance on each participant investor, so that the initial investment can be returned to the estate of a participant investor if the participant investor becomes deceased during the program. Upon termination of the program, all remaining assets will be distributed pro rata among the living participant investors of the investment partnership.
