Pay particular attention to two important characteristics of the computation. First, the Total Cumulative Overall Score is determined by multiplying the average score in each of the areas measured. However, a negative score in any of these areas will result in a Total Performance of "0". Second, the Cumulative Wealth in Qt is equal to the Wealth in Qt and Cumulative Investment in Future in Qt is equal to the Investment in Future in Qt. They are not averaged over the last four quarters. This is because both are already cumulative numbers created since the inception of the company.
