At March 31, 2021, the Company recorded $3.7 million as a right of use asset and $4.9 million as an operating lease liability. At December 31, 2020, the Company recorded $1.8 million as a right of use asset and $3.0 million as an operating lease liability. The Company assesses its right of use asset and other lease-related assets for impairment. There were no impairments recorded related to these assets during the three months ended March 31, 2021 and the year ended December 31, 2020.

As a result of the acquisition of EnvisionTEC, the Company acquired operating, short-term, and finance leases for corporate offices, manufacturing and warehouse facilities, and machineries, increasing the Company’s right of use asset by $1.8 million. The operating leases consist of five real estate leases and six equipment leases with current terms extending from 2021 to 2024. The Company’s finance leases are immaterial as of March 31, 2021.

The Company reviews all supplier, vendor, and service provider contracts to determine whether any service arrangements contain a lease component. The Company identified two service agreements that contained an embedded lease. The agreements do not contain fixed or minimum payments, and the Company has concluded that the variable lease expense was immaterial during the three months ended March 31, 2021 and 2020, respectively.

The rate implicit in the lease is not readily determinable in most of the Company’s leases, and therefore the Company uses its incremental borrowing rate as the discount rate when measuring operating lease liabilities. The incremental borrowing rate represents an estimate of the interest rate the Company would incur at lease commencement to borrow an amount equal to the lease payments on a collateralized basis over the term of the lease.

Future minimum lease payments under noncancelable operating leases, including immaterial future minimum lease payments under finance leases, at March 31, 2021, are as follows (in thousands):
