The Financial Immunization Classic Theory studies the interest rate risk and the necessary conditions to asset liability management. Redington, in 1952, introduced a model of asset liability management. His model considers the initial financial struture, the shifts of the interest rate function represented by z, for z ∈ R, which is added to the initial financial structure, determining the new financial structure. Fisher and Weil, in 1971, studied the case in which the liability is given by a single payment L. The present work considers the value function v(t, s) as known, and includes the case of discontinuous interest rates function. The theorems of Redington and Fisher-Weil are extended to a sequence of asset and liability cash flows for constant shifts.

Abstract
The Financial Immunization Classic Theory studies the interest rate risk and the necessary conditions to asset liability management. Redington, in 1952, introduced a model of asset liability management. His model considers the initial financial struture, the shifts of the interest rate function represented by z, for z ∈ R, which is added to the initial financial structure, determining the new financial structure. Fisher and Weil, in 1971, studied the case in which the liability is given by a single payment L. The present work considers the value function v(t, s) as known, and includes the case of discontinuous interest rates function. The theorems of Redington and Fisher-Weil are extended to a sequence of asset and liability cash flows for constant shifts.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
