LEASES

LEASES

We lease construction and office equipment, distribution facilities and office space. Leases with an initial term of 12 months or less, including month to month leases, are not recorded on the balance sheet. Lease expense for short-term leases is recognized on a straight line basis over the lease term. For lease agreements we have entered into or reassessed we combine lease and nonlease components. While we also own mineral leases for mining operations, those leases are outside the scope of Accounting Standards Update No. 2016-2, Leases (Topic 842). Assets acquired under finance leases are included in property, plant and equipment.

Many of our leases include options to purchase the leased equipment. The depreciable life of assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants. The components of lease expense were as follows:
