At the highest level, plan sponsors strive to have sufficient assets available to meet the pension promises. Exactly what this means in practice changes over time. In fact, this has changed remarkably over the last two decades as we have moved from a purely long-term approach to an increasingly mark-to-market approach driven by legislation and accounting standards.
The youthful pension plan
Although now rare, in the past pension plans were more commonly open to new entrants with participants earning additional benefit accruals with each year of employment. The time horizon created was to all intents and purposes infinite and replenished with new entrants to pay contributions, which indirectly paid pensions.
In this type of plan, a sponsor may adopt an approach akin to an endowment fund with objectives set in real terms (e.g., risk and return targets relative to inflation). A long-term investment horizon can be sought, and the plan can outperform shorter-term investors that may find they are forced sellers when short-term market shocks occur.
The midlife pension plan
Over the last few years, an increasing number of pension plans have been closed to new members — and in some cases, to new accruals for current active members. With no increase in membership and no new benefits earned, this is a fundamental change. Gradually, as the time horizon for payment of the liabilities shortens, management of this liability assumes greater importance, eventually dominating the investment strategy.
Many pension plans acknowledge this trend with well-defined journey plans (also known as glide paths) that state their long-term funding objectives expressed relative to liabilities. Pension plans will also define the time horizon over which they expect to achieve their objectives and their acceptable level of risk.
We feel the importance of implementing this framework increases as the pension plan’s liabilities mature and there is less room to manoeuvre if investment performance is poor.
The mature, self-sufficient pension plan
Some pension plans are fully funded on both a going concern and solvency basis. At this stage, assets may be invested mostly in fixed-income and other low-risk assets (relative to liabilities), as it is highly probable that benefits can be provided without recourse to the sponsor.
