The length of time over which a finance lease is amortized. A finance lease should be amortized over its economic life if it has an ownership transfer or reasonably certain purchase option at the end of the lease. Otherwise, it should be amortized over its lease term. EZLease sets this automatically based on whether or not you set the Ownership Transfer or Reasonably Certain Purchase Option checkboxes, but you can override the choice if you need to. The most common reason would be a lease with ownership transfer with a lease term longer than its economic life, in which case you would normally extend the amortization to cover the entire time the lease is active.
