We currently have a large balance in net book value for leasehold improvements on the balance sheet and the office lease ends in 10 years. The landlord has now asked us to move to a different floor in the building as they need our space for something else. Since the move will likely occur at the end of this year/beginning of next year we need to properly account for the remaining LHI balance. Can I accelerate the depreciation of the remaining LHI to end in December 2018 instead of December 2028? Will I charge all of it to depreciation expense or dos it have to be charged elsewhere? Can anyone point me to the corresponding FASB guidance, I could not find it?
