Operating Lease description |  | Teva determines if an arrangement is a lease at inception. Lease classification is governed by five criteria in ASC 842-10-25-2. If any of these five criteria is met, Teva classifies the lease as a finance lease. Otherwise, Teva classifies the lease as an operating lease. When determining lease classification, Teva’s approach in assessing two of the mentioned criteria is: (i) generally, 75% or more of the remaining economic life of the underlying asset is a major part of the remaining economic life of that underlying asset; and (ii) generally, 90% or more of the fair value of the underlying asset comprises substantially all of the fair value of the underlying asset. |  |
