The objective of this project is three-fold: first, we develop a model that values a pension fund which uses mobile telephone airtime usage costs to accumulate the funds, with all costs associated with running a pension fund considered. Secondly, we develop two models that explain the difference in the accumulated pension fund value from the actual fund value. These models are: reduction in yield model and reduction in contribution model. Finally, we adjust the pension fund valuation model and the reporting models for lapse rates.
