|Leases of Lessee Disclosure||Leases
Operating lease arrangements primarily consist of office leases expiring in various years through 2028. These leases have original terms of approximately 2 to 7 years and some contain options to extend the lease up to 5 years or terminate the lease, which are included in right-of-use assets and lease liabilities 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 March 31, 2021 and December 31, 2020, the weighted average discount rate for operating leases was 3.9% and 4.0%, respectively, and the weighted average remaining lease term for operating leases was 4.6 years as of the end of each of these periods.
The table below presents aggregate future minimum payments due under leases, reconciled to total lease liabilities included in the consolidated balance sheet as of March 31, 2021:
Operating lease cost was $2.5 million and $0.9 million for the three months ended March 31, 2021 and 2020, respectively.
Short-term lease costs for the three months ended March 31, 2021 and 2020 were not material. There were $5.2 million right-of-use assets obtained in exchange for new lease liabilities for the three months ended March 31, 2021. There were no right-of-use assets obtained in exchange for new lease liabilities for the three months ended March 31, 2020.
The Company has subleased a facility that it ceased using in connection with a restructuring plan (Note 4). Such sublease expires in 2021, and future minimum rental income under the sublease is $0.04 million.
Total sublease income related to leased facilities the Company ceased using in connection with a restructuring plan for the three months ended March 31, 2021 and 2020 was approximately $0.04 million and $0.2 million, respectively (Note 4).
