In an earlier paper the control characteristics of the aggregate method of funding were displayed by way of its response to a spike, step and random variation in the earned rate of interest, together with a simple intuitive method of setting the valuation rate of interest.
The projected unit method is analysed here in the same way.
A further algorithm is developed which aims at driving an opening fund and contribution rate to a desired fund and contribution rate in n years, using the smoothest path of contribution rates.
