Macaulay duration matched strategy is a key tool in bond portfolio immunization. It is well known that if term structures are not flat or changes are not parallel, then Macaulay duration matched portfolio can not guarantee adequate immunization. In this paper the approximate duration is proposed...

This paper provides a Markov chain model for the term structure and credit risk spreads of bond prices. It allows dependency between the stochastic process modeling the interest rate and the Markov chain process describing changes in the credit rating of the bonds by their mutual dependency on a...

In this paper we canvass the use of a duration measure based on approximate duration which has the advantage of not being sensitive to non-parallel shifts in the term structure in the same manner as the Macaulay duration. The paper compares the performance of bond immunization strategies based...
