Answer: Liability Gains & Losses
Step-by-step explanation:
The Projected Benefit Obligation refers to the present value of the amount that a company owes its employees as pension if its employees retire with the company so this is a liability to the company.
If this PBO is to change therefore and actuarial gains or losses are recorded from this change, they would affect the liabilities of the company and would therefore have to be referred to as liability gains and losses.
