LEASES

We have operating leases for office space, facilities, equipment, employee housing and certain rig berthing facilities. For all asset classes, except office space, we account for the lease component and the non-lease component as a single lease component. Our leases have remaining lease terms of less than one year to nine years, some of which include options to extend.

We evaluate the carrying value of our right-of-use assets on a periodic basis to identify events or changes in circumstances, such as lease abandonment, that indicate that the carrying value of such right-of-use assets may be impaired.

The components of lease expense are as follows (in millions):

Predecessor

On October 28, 2020, the Bankruptcy Court approved the rejection of certain unexpired office leases and related subleases. The various lease rejections were effective as of September 30, 2020 and October 31, 2020. We recorded an estimated allowed claim of $4.4 million and recognized an expense in Reorganization items, net in our Consolidated Statements of Operations for the year ended December 31, 2020 (Predecessor).
