Leases
We lease certain buildings and plant and equipment. Our leases have reasonably assured remaining lease terms of up to 11 years. Certain leases include options to renew for up to 15 years. At lease inception, we determine the lease term by assuming the exercise of those renewal options that are reasonably certain. Some leases have variable payments, however, because they are not based on an index or rate, they are not included in the measurement of ROU assets and lease liabilities. Variable payments for real estate leases relate primarily to common area maintenance, insurance, taxes and utilities associated with the properties. Variable payments for equipment leases relate primarily to hours, miles, or other quantifiable usage factors, which are not determinable at the time of lease inception. These variable payments are expensed as incurred. The discount rate applied to our leases in determining the present value of lease payments is our incremental borrowing rate based on the information available at the commencement date. Leases with an initial term of 12 months or less are not recorded in our consolidated balance sheets and we recognize lease expense for these leases on a straight-line basis over the lease term.
