At the end of the first entry, an entry has to be recorded for the amortization of lease improvements.
Annual Amortization = Cost of improvement / Life of the improvement
= 33000 / 20
= $1,650
The journal entry would be:
Amortization expense – debit $1650
Accumulated Amortization - credit $1650
The above entry will record an expense and reduce the value of lease improvements in the balance sheet
