Liability Driven Investing

Aligning Asset Risk with Plan Liabilities

Liability-driven investing evaluates portfolio risk in relation to a plan’s ability to meet future benefit obligations, measuring risk in terms of funded status volatility rather than asset volatility in isolation. We help defined benefit plan sponsors manage the interest rate and return-seeking asset risks that contribute to funded status volatility through customized, risk-controlled LDI and de-risking strategies.

Portfolio Fit

Align Portfolio Decisions with Liability Risk

Our approach does not necessarily imply increasing the fixed income allocation; risk tolerance and return requirements determine the appropriate blend of liability-hedging and return-seeking assets. We work closely with clients, consultants and actuaries to understand the liability, customize a strategy, specify a benchmark and risk tolerances and develop portfolio guidelines.

Our LDI capabilities address three liability risks that shape the hedge:

Duration

Measures sensitivity to changes in interest rates. Portfolios may be designed to match liability duration or extend duration to pursue a higher hedge ratio.


Spread

Measures sensitivity to changes in corporate credit spreads. Credit exposure can be calibrated in relation to the plan’s broader asset allocation and return-seeking risk.


Yield Curve

Measures sensitivity to interest rate changes at different points along the curve. Portfolio construction is designed to reduce key-rate and cash flow mismatches relative to the liability.
