ASC 842
A lease with a total lease term, including renewal options that are considered at lease inception to be reasonably certain of exercise, of 12 months or less. Short-term leases are treated like FAS 13 operating leases, with no asset and liability (unless there are scheduled rent changes, which must be leveled over the lease life).
IFSR 16 & GASB 87
A lease with a total lease term, including all renewal options, of 12 months or less.
Note: If you revise a short-term lease in EZLease, and the remaining term after the revision is less than 12 months, the classification can remain short-term. If the extension is for more than 12 months, the lease is reclassified to operating or finance at the revision booking date.
