Under AAS17 a lease is non-cancelable if it is capable of being cancelled only if:
■ the lessor consents to the cancellation;
■ a remote or unexpected contingency occurs that has a significant impact on the terms of the lease;
■ the lessee is required, under the terms of the lease, to enter into another lease for the same or equivalent property with the same lessor or party related to the lessor; or
■ the lease provides for substantial penalties so as to discourage cancellation.
