Increasingly, modern business and investment management techniques are founded on approaches to measurement of profit and risk developed by financial economists. This paper begins by analysing corporate pension provision from the perspective of such financial theory. The results of this analysis are then reconciled with the sometimes contradictory messages from traditional actuarial valuation approaches and the alternative market-based valuation paradigm is introduced. The paper then proposes a successful blueprint for this mark-to-market valuation discipline and considers whether and how it can be applied to pension schemes both in theory and in practice. It is asserted that adoption of this market based approach appears now to be essential in many of the most critical areas of actuarial advice in the field of defined benefit corporate pension provision and that the principles can in addition be used to establish more efficient and transparent methodologies in areas which have traditionally relied on subjective or arbitrary methods. We extend the hope that the insights gained from financial theory can be used to level the playing field between defined benefit and defined contribution arrangements from both corporate and member perspectives.

This Working Party has considered the pensions implications of a prolonged period of low inflation. Experience in the United States of America suggests weaker correlation between equity and bond returns and greater overall volatility of returns. Without a further significant increase in the valuation of equities relative to their underlying economic activity, the cost of pensions will rise, possibly as much as doubling within the next 15 years. It follows that for defined contribution schemes and personal pensions, current contribution levels are likely to produce disappointing and generally inadequate results. Similarly, the costs of defined benefit promises will increase. Future defined benefit provision is also vulnerable to the mismatch of mainly equity assets with mainly fixed liabilities and is therefore difficult to control. Many practical issues of scheme design still reflect past inflation and need to be addressed.

This paper has been written to provoke discussion and will be used as background to the debate on 18 November 2002. An earlier version was produced by the Faculty of Actuaries Pension Research Group and presented as a paper to the Faculty of Actuaries Students' Society.

The conditions under which pension schemes merge is an important issue which has been under-researched. Mergers can affect the strength of the sponsor's covenant and the balance of power between the trustees and the sponsor, as well as the deficit or the surplus of the receiving scheme and its funding ratio. This paper sets out two financial criteria to be met by any pension scheme merger: no profit or loss on merging with another scheme; and no dilution of the funding ratio. After defining a merger basis for valuing the assets and liabilities, and allowing for adjustments to the funding ratio via side receipts and payments; it is shown that, whether or not these criteria are met, depends on the state of the financial markets.
