Dr. Puffer created and implemented a Liability-Driven Investment strategy (LDI) for NAV CANADA’s $3Billion pension plan using derivatives. She was responsible for all aspects of investment management and asset mix for the pension fund. She restructured the real estate and equity portfolios. The strategy reduced the volatility of the plan’s solvency ratio and improved the risk profile of the pension fund. She worked closely with the Board, senior management, unions and the plan actuaries to develop a governance process for the pension plan including risk assessment, risk budgeting, optimization, and risk monitoring.
