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 10 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.

During the year ended December 31, 2019, we recorded lease impairments of $5.6 million related to the impairment of the right-of-use assets associated with an office space and a leased yard facility that were abandoned due to the consolidation of certain corporate offices and leased facilities.

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. During the fourth quarter, we recorded an estimated allowed claim of $4.4 million and recognized an expense in Reorganization items, net on our Consolidated Statement of Operations for the Year ended December 31, 2020. The estimated claim has not yet been settled or paid as of December 31, 2020. Also, in connection with the office lease rejections, as of the Bankruptcy Court approved effective dates above, we reduced our right-of-use asset by a total of $10.5 million and lease liability by a total of $20.4 million and recognized a net gain in Reorganization items of $9.8 million which includes the write off of associated leasehold improvements. Additionally, in connection with the lease rejections, we amended the terms of the lease for our corporate headquarters in Houston, Texas. The amendment reduced the associated right-of-use asset by $6.4 million and lease liability by $10.4 million and we recognized a net gain in Reorganization items of $1.7 million which includes the write-off of associated leasehold improvements.
