Leases
Lessee arrangements
We have operating leases relating to our premises, for which we are the lessee. The most significant leases are for offices in Houston, USA, Liverpool, United Kingdom, Stavanger, Norway and Rio de Janeiro, Brazil.
Lessor arrangements
We also leased three benign environment jackup rigs, namely the West Castor, West Telesto, and West Tucana, to Gulfdrill, a joint venture, for a contract with Gulf Drilling International in Qatar. In June 2024, the Company sold these rigs, along with our 50% equity interest in the Gulfdrill joint venture.
On July 1, 2022, we commenced a lease for our 6th generation drillship, West Gemini, to our Sonadrill joint venture at a nominal charter rate. In May 2024, the charter rate was amended retroactively to January 1, 2024 to reflect the fair market value of the rig.

About Leases Disclosures

Lease disclosures under ASC 842 provide a comprehensive view of a company's leased asset portfolio, including the split between operating and finance leases, discount rates used to present-value future payments, and the maturity schedule of lease obligations. This section reveals a significant source of off-balance-sheet commitments that were largely hidden before the current standard.

Key signals: the weighted-average discount rate affects the size of recorded lease liabilities — a higher rate reduces the reported obligation, so compare the chosen rate against the company's incremental borrowing rate. The operating versus finance lease mix affects both EBITDA and operating income presentation. Watch the maturity table for concentration risk: large payment cliffs in specific years may create cash flow pressure. Variable lease payments excluded from the liability measurement represent real obligations that do not appear on the balance sheet. Compare total lease costs against prior-year operating lease expense to assess the true economic burden.
