[1] Lease expense for operating leases consists of both fixed and variable components. Expenses related to fixed lease payments are recognized on a straight-line basis over the lease term.

[2] Leases with an initial term of 12 months or less are not recorded on the balance sheet and instead expensed on a straight-line basis over the lease term.

[3] Variable lease payments are generally expensed as incurred, where applicable, and include certain non-lease components, such as maintenance, utilities, real estate taxes, insurance and other services provided by the lessor, and other charges included in the lease. In addition, certain of our equipment lease agreements include variable lease payments, which are based on the usage of the underlying asset. The variable portion of payments are not included in the initial measurement of the asset or lease liability due to uncertainty of the payment amount and are recorded as expense in the period incurred.
