Comparative Disclosure Prior to the Adoption of the New Lease Accounting Standard (ASU 2016-02)

Aggregate rental expense for all operating leases amounted to $6.0 million for the year ended December 31, 2018. During the year ended December 31, 2018, we recognized sublease income of $0.3 million related to our leased space in Downers Grove.

Some of our financing leases include provisions to purchase the asset at the conclusion of the lease. The adoption of ASC 842 did not impact the accounting for these leases. Financing leases were not material as of December 31, 2020 and 2019.
