Simulation-Based Comparison of Existent IAS 19 Accounting Options

Abstract: We focus on accounting for unfunded defined benefit pension plans according to IAS 19 and compare the option to recognise any actuarial gain or loss immediately outside profit or loss in a separate statement within equity ('equity approach') with the 'corridor approach'. The objective is to detect systematic differences in long-term pure accounting effects, which can be seen by the different cumulated net-amounts not (yet) recognised in profit or loss. Due to the complexity and the probabilistic elements, human expectations on system behaviour often fail. Therefore, we have performed the first Monte-Carlo-simulation study of the accounting options. The assumptions concerning input data are based on official German statistics and, therefore, are representative at least for Germany and similar countries. As a result, the belief of long-term offsetting of cumulated actuarial gains and losses is not accurate. The former unforeseeable consequences are the following: if we apply the equity approach we identify a tendency for a quasi-permanent cumulated actuarial net-gain (regenerating workforce) or a permanent cumulated actuarial net-loss (degenerating workforce) recognised outside profit or loss. If the corridor approach is applied, a tendency for quasi-permanent cumulated unrecognised net-gains is reported while amortising any corridor excess in the case of a regenerating workforce.
