This paper is a case study, documenting work completed for Institut fur betriebswirtschaftliche Beratung der Kreditwirtschaft GmbH1 (hence forth referred to as IFB) in Köln, Germany. The practicum involved the implementation of an interest rate model for the purpose of valuing the Multi-callable bond. The brief given was to develop a model that could be implemented into the software (Okular) to price the MCB in a fast and accurate way, so as to satisfy the regulatory body that oversees the supervision of the German banking industry. The model chosen to implement was the Hull and White model (1994) which first appeared in the literature in Hull and White (1990) and is often referred to as the modified Vasicek (1977). The 1994 model is developed further and is computationally more efficient. Interest rate models like Vasicek (1977) also appeared in the literature in Courtadon (1982) and Cox, Ingersoll, and Ross (1985). The approach of these models is to fit the market data and imply the yield curve and its evolutionary process. The Hull and White(1990) uses a different process. By taking the current yield curve as a given input, this model produces an arbitrage free yield curve that is consistent with the data. This style of model was seen first in Ho and Lee (1986), but the Hull and White (1994) is developed further to incorporate a mean reversion parameter and time dependent volatility term. In the Hull and White (1994), the trinomial tree process is manipulated to reproduce the stochastic process of the short rate with mean reversion. The tree is truncated to stop the evolution of negative interest rates, which have always bothered practitioners, and is also made computationally more efficient by this truncation process. One of the reasons this model was chosen is because of the vast amount of literature available on the implementation of this model, most notably Hull and White (1994), Numerical procedures for implementing term structure models I: single factor models, where the model in question is developed ...
