As of September 30, 2020, we have additional operating leases for building spaces that have not yet commenced, and some building spaces are being constructed by the lessors and their agents. These leases have terms of up to 12 years and are expected to commence on various dates during 2020 and 2021 when the construction is complete and we take possession of the buildings. The undiscounted lease payments for these leases, which are not included in the tables above, aggregate $142.
