Patent ID: 8566196

Claim:
A computer implemented method: (a) receiving, using a data processing system, user inputs comprising an initial value of the portfolio, a current age of a first joint investor, and a current age of a second joint investor; (b) providing, using the data processing system, data indicating one of cumulative probabilities of living to an age of death and cumulative probabilities dying at an age of death for persons of a given age group; (c) randomly drawing, using the data processing system, a number between 0 and 1 for the first joint investor and a number between 0 and 1 for the second joint investor; (d) defining, using the data processing system, the randomly drawn number of step (c) for the first joint investor as one of said one of cumulative probabilities of living to an age of death and cumulative probabilities of dying at an age of death for the first joint investor and the randomly drawn number of step (c) for the second joint investor as one of said one of cumulative probabilities of living to an age of death and cumulative probabilities of dying at an age of death for the second joint investor; (e) determining, using the data processing system, an age of death of the first joint investor and the second joint investor in accordance with said data based on the current age of the respective first and second joint investors and the randomly drawn numbers of step (c); (f) determining, using the data processing system, the greater age of death of the first and second joint investors by comparing the age of death of the first joint investor determined in step (e) with the age of death of the second joint investor determined in step (e); (g) computing, using the data processing system, a future value of the portfolio using said greater age of death of the joint investors, a predetermined rate of return, and the initial value of the portfolio; and (h) outputting the computed future value of the portfolio.
