This column is displayed only for leases with rent leveling. The first line shows the deferred rent balance at the beginning of the period. The second line shows the level rent accrual for the period. The third line shows the difference between the level rent and the cash rent for the period. If you have selected “Smooth rent leveling” in System Options, the difference is based on the cash rent accrual; otherwise, it is based on the cash rent paid. See System Options for more details on the significance and purpose of this choice. The fourth line shows the deferred rent asset (if a debit) or liability (if a credit). For typical Lessee leases with increasing rents, you will have a liability.
