Could you please clarify my understanding that if the Company incurs dismantling/discommisioning cost (for example Future dismantling cost of 1000 in 3 years time at discount rate 10%) => The present cost of Dismantling: 1000/1.1^3 = 751 should be added to the cost of PPE but the interest should be recorded to P&L for three years as below:
Year 1: 751 *10% Year 2: (751 + 751 *10%) * 10% Year 3: ((751 + 751 *10%) * 10%)*10%
Yes, that is correct. We discount back to present value and capitalise the costs. The unwinding of the discount is then taken through profit or loss as a finance cost.
