On January 1, 2019, we adopted new accounting guidance under Accounting Standards Codification Topic 842 (ASC 842) Leases. ASC 842 superseded prior lease accounting guidance and established new criteria for recognizing right-of-use assets and lease liabilities for operating lease arrangements on our Consolidated Balance Sheet. We elected to adopt this guidance utilizing the optional transition method that allowed us to not retrospectively revise prior period balance sheets to include operating leases, and to only include the disclosures required under ASC 842 for the periods subsequent to adoption.

We have concluded that when an agreement grants us the right to substantially all of the economic benefits associated with an identified asset, and we are able to direct the use of that asset throughout the term of the agreement, we have a lease. We lease certain facilities, manufacturing machinery and equipment, and furniture under finance leases, and we also lease certain commercial office and production facilities, manufacturing machinery and equipment, vehicles and other assets under operating leases. Some of our leases include options to extend or terminate the leases and these options have been included in the relevant lease term to the extent that they are reasonably certain to be exercised.

The lease consideration for some of our facilities and machinery and equipment is variable, as it is based on various indices or usage of the underlying assets, respectively. Variable lease payments based on indices have been included in the related right-of-use assets and lease liabilities on our Consolidated Balance Sheet, while variable lease payments based on usage of the underlying asset have been excluded as they do not represent present rights or obligations.

As the rate implicit in the lease is typically unknown, the discount rate used to determine the lease liability for the majority of our leases is the collateralized incremental borrowing rate in the applicable geographic area for a similar term and amount as the lease agreement.

We have elected to adopt, for all classes of underlying assets, a package of practical expedients provided under ASC 842 that allow us to 1) not reassess whether existing or expired contracts contain or contained a lease; 2) not reassess the lease classification (operating or financing) of our existing leases at adoption; and 3) not reassess initial direct costs for existing leases.

ASC 842 also provides a practical expedient that allows companies to exclude balance sheet recognition of right-of-use assets and associated liabilities for lease terms of 12 months or less, which we have elected as part of our adoption of ASC 842 for all classes of underlying assets. We do not include right-of-use assets and operating lease liabilities on our Consolidated Balance Sheet for leases with a term of 12 months or less.

We have also elected to adopt the practical expedient under ASC 842 to not separate lease and non-lease components in contracts that contain both. These lease agreements are accounted for as a single lease component for all classes of underlying assets.

As of December 31, 2019, we have entered into additional leases that have not yet commenced of approximately $78.9 million, which primarily reflects a lease of a facility in the United States, which has a term of 15 years, and the lease of our new European headquarters and engineering center in Langen, Germany, which has a term of 20 years. These leases are expected to commence in 2020.

As we elected to adopt the guidance under ASC 842 utilizing the optional transition method that allowed us to only include the disclosures required under ASC 842 for the periods subsequent to adoption, we are required to include the disclosures under ASC 840 for the period prior to adoption.

At December 31, 2018, the gross asset cost of our capital leases was $10.5 million and the net book value included in property, plant and equipment, net on the balance sheet was $3.4 million. The weighted-average interest rate on these capital lease obligations at December 31, 2018 was 7.9%.
