Finance Leases

We have a finance lease obligation related to our manufacturing facility in Eschenbach, Germany. Under the terms of the lease agreement, we have an option to purchase the property upon the expiration of the lease in 2021 at a price which is the greater of (i) the then-current market value or (ii) the residual book value of the land including the buildings and installations thereon. Our finance lease obligation related to this facility was $4.5 million as of both December 31, 2020 and 2019. The finance lease right-of-use asset balance for this facility was $6.5 million and $6.3 million as of December 31, 2020 and 2019, respectively. Accumulated amortization related to our finance lease right-of-use assets was $4.5 million and $3.8 million as of December 31, 2020 and 2019, respectively. All other finance lease obligations, finance lease right-of-use assets and accumulated amortization were cumulatively immaterial as of December 31, 2020 and 2019.

Amortization expense related to our finance lease right-of-use assets, which is primarily included in the “Cost of sales” line item of the consolidated statements of operations, was immaterial for each of the years ended December 31, 2020 and 2019. Interest expense related to our finance lease obligations, which is included in the “Interest expense, net” line item of the consolidated statements of operations, was immaterial for each of the years ended December 31, 2020 and 2019. Payments made on the principal portion of our finance lease obligations were immaterial for each of the years ended December 31, 2020 and 2019.

Operating Leases

We have operating leases primarily related to building space and vehicles. Renewal options are included in the lease term to the extent we are reasonably certain to exercise the option. The exercise of lease renewal options is at our sole discretion. We account for lease components separately from non-lease components. The incremental borrowing rate represents our ability to borrow on a collateralized basis over a similar lease term.

Practical Expedients

We also elected the package of practical expedients that allows us to carry forward the historical lease classification and accounting for indirect costs for any existing leases.
