Purpose: This paper argues that the accounting standards’ requirement for the valuation of pension scheme liabilities, potentially produces an artificial result which is at odds with the “faithful representation” and “relevance” objectives of these standards. Design/methodology/approach: The approach is a theoretical analysis of the relevant reporting standards with the use of a practical example to demonstrate the impact where trustees adopt a hedged approach to portfolio investment. Findings: Where a pension fund engages in asset liability matching and invests in “risk – free” assets, the term, quantity and duration/maturity of which, is intended to match some or all of its scheme liabilities, the required accounting treatment potentially results in the sponsoring company’s financial statements reporting fluctuating surpluses or deficits each year which are potentially ill-informed and misleading. Originality/value: Pension scheme surpluses or deficits reported in the financial statements of listed companies are potentially very significant numbers, however the dangers posed by theoretical nature of the calculation has largely gone unreported.
