Private & Confidential Case Study: Volatility Control Equities 19 August 2013 1

Case Study: Adopting a risk controlled approach to managing equity allocation

Situation:

• A c£3.5bn closed and mature pension scheme with weak sponsor covenant, facing a deficit of c£300m on a self sufficiency basis.

• The Scheme relies primarily on returns from investment strategy to fund its deficit in the absence of significant sponsor contributions.

• The Scheme is therefore highly path dependent and vulnerable to stress events which could throw it off course from its flight path.

Task:

• To reduce downside risk from equities while maintaining returns required for the Scheme’s path to full funding.

• Redington recommended for the Scheme to adopt a risk controlled approach to managing its equity allocation. Under this approach, the Scheme’s equity exposure is dynamically managed to achieve a target volatility level.

- For example as equity volatility rises, exposure to equities is reduced towards cash to keep the volatility at the target level

- Historical analysis showed that, across equity markets and time periods, adopting this approach enables the Scheme to limit draw-downs and deliver equity-like returns with substantially lower volatility

• A further advantage of managing equity against a target volatility is that it cheapens the cost of buying explicit downside protection via a “put option” .

- For example, the cost to protect a global equity portfolio against a fall in value of more than 10% over a one-year period may cost between 3-4%, however, the same protection for a global, volatility controlled index costs less than 1%).

Action:

• Following Trustee Training and Board Approval, the Trustees moved the equity benchmark to a volatility controlled index with a target volatility of 10% and bought a put option at a strike of 90% on the index.

• Redington also advised on other key parameters of the structure including implementation vehicle, underlying index and management of currency hedging.

• The structure was executed by the Scheme’s LDI manager with oversight by Redington as a total return swap with an investment bank.

Risk-Return Illustration of Scheme’s Equity Portfolio

As a result, the Scheme:

o Manages its equity exposure in a risk controlled way through a target volatility of 10%.

o Reduced its equity risk by two thirds i.e. from c30% to 10% of notional equity exposure.

o Decreased downside risk by buying explicit protection at affordable levels while still maintaining its path to full funding.

o Diversified its portfolio further between different risk factors such as credit, illiquidity, insurance risks by reducing relative equity risk.
