|Leases of Lessee Disclosure [Text Block]||Leases
Operating lease arrangements primarily consist of office leases expiring at various years through 2028. These leases often have original terms of 2 to 7 years and contain options to extend the lease up to 5 years or terminate the lease, which are included in leased right-of-use assets and lease liabilities in the consolidated balance sheet when the Company is reasonably certain it will renew the underlying leases. Since the implicit rate of such leases is unknown and the Company is not reasonably certain to renew its leases, the Company has elected to apply a collateralized incremental borrowing rate to facility leases on the original lease term in calculating the present value of future lease payments. As of December 31, 2020 and 2019, the weighted
average discount rate for operating leases was 4.0% and 5.0%, respectively, and the weighted average remaining lease term for operating leases was 4.6 years and 2.9 years, respectively.
The table below presents aggregate future minimum payments due under leases, reconciled to lease liabilities included in the consolidated balance sheet as of December 31, 2020:
Operating lease costs were $5.2 million, $3.1 million and $4.5 million for the years ended December 31, 2020, 2019 and 2018, respectively.
Short-term lease costs for the years ended December 31, 2020 and 2019 were not material. There were $15.9 million and $0.5 million of right-of-use assets obtained in exchange for new lease liabilities for the years ended December 31, 2020 and 2019, respectively, including $1.8 million in right-of-use assets from acquisitions in 2020 (Note 3).
The Company has a subleased facility that it ceased using in connection with a restructuring plan (Note 4). Such sublease expires in fiscal 2021, and future minimum rental income under the sublease is $0.1 million.
Total sublease income related to leased facilities the Company ceased using in connection with a restructuring plan for the years ended December 31, 2020, 2019 and 2018 was approximately $0.4 million, $1.2 million and $2.4 million, respectively (Note 4).
In the year ended December 31, 2019, the Company terminated certain facility leases and a related sublease, which were due to expire in 2022 to 2023, upon release from the landlords. The Company had previously ceased use of all or portions of the related facilities. As a result of such terminations, the Company reduced leased right-of-use assets by approximately $9.2 million, lease liabilities by approximately $10.1 million, and other related liabilities by approximately $0.3 million in the consolidated balance sheet. The related net impact in the consolidated statement of operations was a gain of approximately $1.2 million, which consisted of a gain on extinguishment of lease-related liabilities of $10.4 million, partially offset by impairment of leased right-of-use assets of $9.2 million. The Company also recorded impairment of related leasehold improvements of $1.4 million.
The entire disclosure for lessee entity's leasing arrangements including, but not limited to, all of the following: (a.) The basis on which contingent rental payments are determined, (b.) The existence and terms of renewal or purchase options and escalation clauses, (c.) Restrictions imposed by lease agreements, such as those concerning dividends, additional debt, and further leasing.
