This note highlights a particular issue faced by actuaries and accountants when they set out to build effective valuation tools. Specifically, our aim is to highlight some of the disadvantages of the fashionable so-called deflator approach to contingent claims valuation. We contrast the deflator methodology with the widely-used risk-neutral pricing technique and explain why we believe it is highly inefficient, cumbersome and costly compared to conventional methods.
