At the end of 2017, I set up impairment contra-assets in order to write down the value of the Leasehold Improvements booked prior to the impairment analysis. I set them up so that they would fully depreciate at the end of the lease, as the LHI assets will do. In theory, this makes sense to me--assuming we do not renew the lease, all assets will be fully depreciated at the end. The problem I'm having now is that the impairment asset has a more accelerated depreciation rate because the In Service Date is months/years after the other LHI assets. For most of the impaired locations, I now have a negative Net Book Value, but still have 6 years left.
We are currently working through the annual impairment analysis, and the negative NBV is skewing the results.
Is there a way to set the asset up so that I control how much it depreciates each month, and then know that I need to write off the remaining balance at the end of the lease?
Or is there a better way to handle the scenario?
