Found on the Inception tab. If you revise the lease, in most cases it needs to be tested for capital vs. operating both from the lease inception date and separately as of the revision date. Therefore, you must enter the incremental borrowing rate, implicit rate (if known; this is calculated automatically if the unguaranteed residual is filled in), unguaranteed residual (if known), economic life, and fair value to enable testing. The Revision Booking Date is the date as of which the revision should be entered onto the books. EZLease automatically determines the First Date of Change, which is the date as of which the first change in terms takes effect. This set of fields is not available when first entering a new lease.
