The Company determines if an arrangement is a lease at inception of a contract. Substantially all of the Company’s leases are operating leases. A significant portion of the Company’s operating lease portfolio includes manufacturing sites, component warehouses and corporate offices. The remaining lease terms on the majority of the Company’s leases are between 1.5 and 19 years, some of which include options to extend the lease terms. Leases with initial term of 12 months or less are not recorded on the consolidated balance sheet. Operating lease ROU assets are presented within long term assets, the current portion of operating lease liabilities are presented within current liabilities and the non-current portion of operating lease liabilities are presented within long term liabilities on the consolidated balance sheet.

ROU assets represent the Company’s right to use an underlying asset during the lease term and the lease liabilities represent the Company’s obligation to make the lease payments arising during the lease. ROU assets and liabilities are recognized at commencement date based on the net present value of fixed lease payments over the lease term. The Company’s lease term includes options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. As most of the Company’s operating leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. Operating lease expense is recognized on a straight-line basis over the lease term. The components of the lease costs were as follows:
