Description: As we meet with pension plan sponsors and consultants across Canada we find that the subject of liability-driven investing LDI comes up repeatedly even when we do not initiate the discussion. We also find that LDI seems to mean something different to each person we meet. Is LDI just a new name for asset/liability management ALM? Or is LDI just about hedging interest rate risks with fancy securities? In this article we describe a framework for understanding what LDI is, how it relates to ALM, and how it can be used to solve real-life problems for Canadian pension funds.
