Description: This paper reviews Redington's theory of immunization and sketches how it may be extended to the general case of stochastic flows by means of modern option-pricing theory. From the Actuarial Research Clearing House 1992 Vol. 1 .

Description: In this paper, a general multivariate duration analysis is introduced that does not depend on a mathematical formulation of the way in which a yield curve moves. A discussion of the paper follows. From Transactions of Society of Actuaries 1991, Vol. 43.

Description: This paper discusses extending the general nonparallel shift approach to duration analysis developed previously and explores the immunization model within the multivariate context. A discussion of the paper follows. From Transactions of Society of Actuaries 1991, Vol. 43.
