We have operating leases for many of our design centers that expire at various dates through fiscal 2040. In addition, we also lease certain tangible assets, including computer equipment and vehicles with initial lease terms ranging from three to five years. We determine if a contract contains a lease at inception based on our right to control the use of an identified asset and our right to obtain substantially all of the economic benefits from the use of that identified asset. Certain operating leases have renewal options and rent escalation clauses as well as various purchase options. We assess these options to determine if we are reasonably certain of exercising these options based on all relevant economic and financial factors. Any options that meet these criteria are included in the lease term at lease commencement.

The Company's lease terms and discount rates are as follows:

Lease expense for operating leases consists of both fixed and variable components. Expense related to fixed lease payments are recognized on a straight-line basis over the lease term. Variable lease payments are generally expensed as incurred, where applicable, and include certain index-based changes in rent, certain non-lease components, such as maintenance and other services provided by the lessor, and other charges included in the lease. Leases with an initial term of twelve months or less are not recorded on the balance sheet. In addition, certain of our equipment lease agreements include variable lease payments, which are based on the usage of the underlying asset. The variable portion of payments are not included in the initial measurement of the asset or lease liability due to uncertainty of the payment amount and are recorded as lease expense in the period incurred.

As of  December 31, 2020, we have entered into two additional financing leases for computer equipment, which have not yet commenced and are therefore not part of the tables above nor included in the consolidated balance sheet as property, plant and equipment (assets) and other current and non-current liabilities. The leases commence when we obtain possession of the underlying leased assets which were in January 2021. The leases are for a period of three years and have aggregate undiscounted future rent payments of $1.4 million.

As of December 31, 2020, we did not have any operating leases that had not commenced.
