Accounting for the Obligation under a Defined Benefit Plan :

An enterprise should account not only for its legal obligation under the formal terms of a defined benefit plan, but also for any other obligation that arises from the enterprise’s informal practices. Informal practices give rise to an obligation where the enterprise has no realistic alternative but to pay employee benefits. An example of such an obligation is where a change in the enterprise’s informal practices would cause unacceptable damage to its relationship with employees.

 

The formal terms of a defined benefit plan may permit an enterprise to terminate its obligation under the plan. Nevertheless, it is usually difficult for an enterprise to cancel a plan if employees are to be retained. Therefore, in the absence of evidence to the contrary, accounting for post-employment benefits assumes that an enterprise which is currently promising such benefits will continue to do so over the remaining working lives of employees.
