Answer:
$ 50,000 is the gain on the settlement
Step-by-step explanation:
Given:
The estimated asset retirement obligation (ARO) = $ 100,000
Expected cash flow before inflation = $ 190,000
Expected cash flow adjusted for inflation and market risk = $220,000
Now,
gain (or) loss on the settlement of the ARO liability
= ARO liability - the actual settlement cost
on substituting the respective values, we get
gain or loss on the settlement of the ARO liability = $ 220,000 - $ 170,000
or
gain or loss on the settlement of the ARO liability = $ 50,000
Also,
Since, the initial liability is to be increased to the expected cash flow
therefore, it $ 50,000 is the gain on the settlement
