The UK defined benefit pension scheme landscape has changed dramatically over the last few decades. During this period of change, conflicting views regarding the measurement of both assets and liabilities has made communication challenging. This has led to an under appreciation of risk and often suboptimal decision making. This paper seeks to draw together a variety of contrasting views to provide a coherent framework for stakeholders to meet pension scheme obligations over time.The proposed framework encourages agreement between both scheme sponsors and trustees towards a common target through a well articulated plan, or "flight path". In addition, the proposed flight path structure provides a common basis underpinning the measurement of both pension obligations and the risks inherent in any plan to meet those obligations.In an alternative recent framework, the recent paper by the Discount Rate Steering Committee (2011) proposed that discount rate calculations could be broadly split between matching calculations and budgeting calculations, although in their final update (2011) they noted that "in limited circumstances, a blend of matching and budgeting can be relevant." In their final update (2011), the Discount Rate Steering Committee also published in appendix 2 a table setting out how their recommendations, including the budgeting/matching framework, corresponded to the Technical Actuarial Standards published by the Board for Actuarial Standards. This paper develops the existing research beyond discount rates.
Flight pathsAs defined benefit pension schemes close to new members and to future accrual (The Pension Regulator's Purple Book 2010), the focus of sponsors and trustees tends to change.Many traditional valuation methods focused on the ongoing nature of schemes, whereas the recent trend has been towards an end game. The change in employer debt regulations on 11June 2003 together with the mass extinction of discretionary increases have also hardened the obligations reinforcing this trend. This focus on an end game is likely to give greater commonality of objectives.Once a common goal is agreed, then stakeholders can focus on the critical stage of the process, which is how they intend to get to their target, also known as a flight path. Any measurement information should support this decision making, rather than being an end in itself.One particular area of debate, which this paper addresses, is how to reconcile the views held by financial economists and those of other market analysts. This paper proposes a robust framework for allowing for investment returns above "risk free" rates.The authors note that the recent crisis has highlighted, once again, that nothing in life is risk free. However, "risk free" rates form a common building block and useful short-hand for much actuarial and financial economic analysis. We have chosen to side-step this debate in this paper. The reader may choose to interpret "risk free" in a UK context as a low credit risk instrument such as a gilt or a suitably well collateralise...
