The Company determines whether an arrangement is or contains a lease at the inception of the arrangement. Operating leases are included in other non-current assets, accrued expenses and other non-current liabilities in our condensed consolidated balance sheets. Finance leases are included in property, plant and equipment, net, short-term debt and long-term debt (less current portion) in our condensed consolidated balance sheets.

Right-of-use (“ROU”) assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Finance and operating lease ROU assets and liabilities are recognized at the commencement date based on the present value of the lease payments over the lease term. Since we generally do not have access to the interest rate implicit in the lease, the Company uses our incremental borrowing rate (for fully collateralized debt) at the inception of the lease in determining the present value of the lease payments. The implicit rate is, however, used where readily available. Lease expense under operating leases is recognized on a straight-line basis over the term of the lease. Certain of our leases contain both lease and non-lease components, which are accounted for separately.

The Company has operating and finance leases for office facilities, a data center and certain equipment. The remaining terms of our leases range from over one year to eight years. Certain leases include options to extend the lease term for up to ten years, as well as options to terminate which have been excluded from the term of the lease since exercise of these options is not reasonably certain.
