If you haven’t filled in the Useful Life, enter the ARO’s end date. This cannot be later than the Effective End date of the lease. This can be different for each layer of an ARO. An ARO Only record is automatically extended to match the longest-lived ARO.
If you change the end date of an existing ARO, and choose Revise (rather than Replace), the remaining ARO is recalculated using the new end date. The change in the ARO is added to or subtracted from both the ARO liability and the ARC asset.
The ARO header shows the latest layer end date.
