Welcome.
This is the home page for my website on Time Value of
Money (TVOM) concepts.
This site provides reference material for understanding and applying
TVOM theory.
Actuaries typically refer to this material as part of the "general
theory of interest rates".
However, the perspective here is purely financial with an emphasis on
the fundamental building blocks of quantitative investment analysis.
