We generally do not offer renewal terms or purchase options in our leases, although certain of our operating leases allow the lessee the option to extend the lease for an additional term. Operating leases with fixed rentals and step rentals are recognized on a straight-line basis over the term of the initial lease, assuming no renewals. Operating lease rentals that adjust based on a London Interbank Offered Rate (“LIBOR”) index are recognized on a straight-line basis over the lease term using the prevailing rate at lease commencement. Changes to rate-based lease rentals are recognized in the statements of income in the period of change. Revenue is not recognized when collection is not reasonably assured. When collectability is not probable, the customer is placed on non-accrual status, and revenue is recognized when cash payments are received.</span></div>
