Since pensions and other post-employment benefits (OPRB) are both post-retirement benefits so there are similarities and differences in considering GAAP for OPRBs. The basic argument that accounting for OPRBs should be similar to the principles used for pensions is they both involve the concept of a liability. Some argue that a company offering OPRBs is essentially providing deferred compensation to employees because the benefits received during retirement were earned during the period of employment. Others argue that many OPRBs do not have the same explicit legal contract as a pension agreement, and the obligation of the company to continue to provide benefits may not be formally stipulated in a contract. Some argue that there is no liability if the company has the right to withdraw the benefits. What viewpoint does GAAP take and why? Which viewpoint do you support?
