Why is a pre-tax discount rate used in the initial recognition of a decommissioning provision?

• A. It reflects market risk
• B. It reflects tax policy
• C. It must be equal to inflation
• D. It is not used

Answer: (A)

The main idea is that decommissioning obligations are future cash outflows, so we measure them at present value. The discount rate used must reflect current market assessments of the time value of money and the risks specific to that liability. That market-based, pre-tax rate captures how money today is worth less tomorrow and the uncertainty around the future settlement, independent of taxes. Using a pre-tax rate also keeps the measurement consistent with how the liability’s cash flows are expected to occur, with tax effects treated separately. Inflation isn’t a required input to be equal to the rate, and we do use a discount rate, so the best description is that the rate reflects market risk.
