Debt Disclosure [Abstract]
Debt	Debt Second A&R Waiver On July 15, 2020, the Company, certain lenders party thereto, Citibank, N.A., as administrative agent (the “Agent”), and the other parties party thereto entered into a Second Amended and Restated Waiver to Fourth Amended and Restated Credit Agreement (the “Second A&R Waiver”), which amends, restates and replaces the Amended and Restated Waiver to Fourth Amended and Restated Credit Agreement, dated June 30, 2020 (the “A&R Waiver”), which was previously entered into by the Company, certain lenders party thereto, the Agent and the other parties thereto and which amended, restated and replaced the Waiver to Fourth Amended and Restated Credit Agreement, dated June 1, 2020, which was previously entered into by the Company, certain lenders party thereto, the Agent and the other parties party thereto (the “Initial Waiver”). The Initial Waiver was entered into under the Company’s Fourth Amended and Restated Credit Agreement dated May 7, 2013 (as amended, the “revolving credit facility”) to waive any resulting default or event of default attributed to any failure by the Company or any of its subsidiaries to make all or any part of their required interest payments due (i) on June 1, 2020 with respect to the Company’s 4.875% Senior Notes due 2022 (the “2022 Notes”) and 5.40% Senior Notes due 2042 (the “2042 Notes”) (collectively, the “June 1 Interest Payments”) and (ii) on June 15, 2020 with respect to the Company’s 7.375% Senior Notes due 2025 (the “2025 Notes”) (the “June 15 Interest Payments” and together with the June 1 Interest Payments, the “June Interest Payments”). The A&R Waiver was entered into by the parties thereto to continue to waive any default or event of default addressed in the A&R Waiver as well as to also waive any default or event of default under the revolving credit facility resulting from any cross-defaults (the “June 1 Cross-Defaults”) under the 2022 Notes, 2042 Notes, 2025 Notes, the 4.75% Senior Notes due 2024 (the "2024 Notes") and the 5.85% Senior Notes due 2044 (the "2044 Notes" and, collectively, the “Defaulted Notes”) in respect of the failure to pay the June 1 Interest Payments. The Second A&R Waiver was entered into to continue to waive any default or event of default under the revolving credit facility attributed to (i) the failure to make the June Interest Payments and (ii) the June 1 Cross-Defaults. Additionally, the Second A&R Waiver waived any default or event of default under the revolving credit facility attributed to (i) any failure by the Company or any of its subsidiaries to make all or any part of their required interest payments due on (a) July 15, 2020, with respect to the Company’s 2024 Notes and 2044 Notes, (b) July 31, 2020, with respect to the Company’s 8.00%Senior Notes due 2024 and with respect to a subsidiary of the Company’s 3.00% Exchangeable Notes due 2024 and (c) August 1, 2020, with respect to the Company’s 7.75% Senior Notes due 2025, (ii) any resulting cross-defaults under the Defaulted Notes in respect of the failure to pay the June Interest Payments and (iii) an additional waiver relating to a vendor payment. The Second A&R Waiver will remain in effect until the earliest of (i) August 3, 2020, (ii) termination or invalidity of the Forbearance Agreement (as defined below), the Forbearance Agreement ceasing to be in full force and effect or amendment of the Forbearance Agreement without consent of the requisite number of revolving credit facility lenders, (iii) acceleration by the holders of any of the Defaulted Notes in accordance with the terms of the Defaulted Notes and (iv) the date on which the aggregate amount of advances (excluding letter of credit obligations) outstanding under the revolving credit facility exceeds $630.0 million. The Second A&R Waiver includes customary representations and does not limit, impair or constitute a waiver of the rights and remedies of the lenders or the Agent, and except as expressly provided in the Second A&R Waiver and does not amend or affect the terms of the revolving credit facility. Noteholder Forbearance On July 15, 2020, the Company entered into a Forbearance Agreement (the “Forbearance Agreement”) pursuant to that certain indenture dated July 21, 2009 between the Company and U.S. Bank National Association, as indenture trustee, under which the respective Defaulted Notes were issued with certain beneficial holders or investment managers or advisors for such beneficial holders (the “Supporting Holders”). At the time of entry into the Forbearance Agreement, the Supporting Holders held (i) approximately 44.0% of the outstanding 2022 Notes, (ii) approximately 74.2%of the outstanding 2024 Notes, (iii) approximately 65.3% of the outstanding 2025 Notes, (iv) approximately 68.9% of the outstanding 2042 Notes and (v) approximately 82.9%of the outstanding 2044 Notes. The parties previously entered into a Forbearance Agreement on June 30, 2020 that expired on July 15, 2020. Pursuant to the Forbearance Agreement, the Supporting Holders have agreed to (i) forbear from the exercise of certain rights and remedies that they have under the related indenture or applicable law with respect to certain specified defaults and events of defaults (including cross-defaults as a result of an acceleration) and (ii) in the event that the applicable trustee or any holder or group of holders takes any action which results in an acceleration during the Forbearance Period (as defined below), to deliver written notice to the applicable trustee to rescind such acceleration and its consequences and take all other action in their power to cause such acceleration to be rescinded and annulled. The Company and the Supporting Holders have agreed to continue this forbearance until the earlier of (i) August 3, 2020, (ii) the occurrence of any other default or event of default under the related indenture that is not cured within any applicable grace period, (iii) the acceleration of the Company’s obligations under the revolving credit facility, (iv) the termination or invalidity of the Second A&R Waiver, the Second A&R Waiver otherwise ceasing to be in full force and effect, or the Second A&R Waiver being amended, supplemented or otherwise modified in each case without the consent of the Supporting Holders, (v) the commencement of a case under title 11 of the United States Code or any similar reorganization, liquidation, insolvency or receivership proceeding by or against the Company or a subsidiary of the Company or (vi) the failure of the Company to timely comply with any term, condition or covenant set forth in the Forbearance Agreement (such period, the “Forbearance Period”). Senior Notes We did not make interest payments due in June and July 2020 on the Defaulted Notes. The June 2020 missed interest payments represent current events of default under the Defaulted Notes. We have entered into the Forbearance Agreement pursuant to which certain holders of our senior notes have agreed to forbear from the exercise of certain rights and remedies that they have with respect to certain specified defaults and events of defaults (including cross-defaults). However, the events of default under the Defaulted Notes have not been waived and still exist, and the Forbearance Agreement will terminate automatically on August 3, 2020 and may be terminated upon certain other events that may occur prior to August 3, 2020. Accordingly, the amounts outstanding under the Defaulted Notes were classified as current in the accompanying Condensed Consolidated Balance Sheet as of June 30, 2020. As a result of the Rowan Transaction, we acquired the following senior notes issued by Rowan Companies, Inc. ("RCI") and guaranteed by Rowan: (1) $201.4 million in aggregate principal amount of 7.875% unsecured senior notes due 2019, which have been repaid in full, (2) $620.8 million in aggregate principal amount of 4.875% unsecured senior notes due 2022, (3) $398.1 million in aggregate principal amount of 4.75% unsecured senior notes due 2024, (4) $500.0 million in aggregate principal amount of 7.375% unsecured senior notes due 2025, (5) $400.0 million in aggregate principal amount of 5.40% unsecured senior notes due 2042 and (6) $400.0 million in aggregate principal amount of 5.85% unsecured senior notes due 2044. On February 3, 2020, Rowan and RCI transferred substantially all their assets on a consolidated basis to Valaris plc, Valaris plc became the obligor on the notes and Rowan and RCI were relieved of their obligations under the notes and the related indenture. Revolving Credit Facility As of June 30, 2020, we had $588.8 million outstanding under our credit facility, inclusive of $37.8 million in letters of credit, leaving $1.0 billion of undrawn capacity available. Our revolving credit facility requires compliance with covenants to maintain specified financial and guarantee coverage ratios, including a total debt to total capitalization ratio that is less than or equal to 60%. In the first six months of 2020, we incurred impairments of $3.6 billion, which contributed to an increase in the total debt to total capitalization ratio to 57.7% as of June 30, 2020. As of June 30, 2020, we were in compliance with our debt covenants due to the Second A&R Waiver. There is a significant level of uncertainty that we will remain in compliance with our credit facility covenants during the next twelve months. The full impact that the pandemic and the decline in oil prices and demand will have on our results of operations, financial condition, liquidity and cash flows is uncertain. If we were to violate the covenants of the revolving credit facility, further borrowings under the credit facility would not be permitted, absent a waiver in respect of the resulting event of default, and all outstanding borrowings could become immediately due and payable by action of lenders holding a majority of the commitments under the facility. Any such acceleration would trigger a cross-acceleration event of default with respect to approximately $2.1 billion outstanding under the Defaulted Notes. The failure to make the interest payments due in June 2020 on the Defaulted Notes would have represented an event of default under the revolving credit facility if it had not been waived pursuant to the Second A&R Waiver. We have entered into the Second A&R Waiver pursuant to which the lenders under our revolving credit facility have waived certain defaults and events of default under the revolving credit facility, including in relation to the non-payment of interest under the Defaulted Notes. However, the Second A&R Waiver will terminate automatically on August 3, 2020 and may be terminated upon certain other events that may occur prior to August 3, 2020, including if advances outstanding under the revolving credit facility exceed $630.0 million. Accordingly, the amounts outstanding under the revolving credit facility were classified as current in the accompanying Condensed Consolidated Balance Sheet as of June 30, 2020. The revolving credit facility generally limits the company to no more than $200.0 million in available cash (including certain liquid investments as defined in the facility documents), and requires consent of all lenders for draws on the facility that would result in the company having more than $200.0 million in available cash and liquid investments. Furthermore, the agent under the revolving credit facility has reserved the right to assert that a material adverse effect has occurred based on changes in the oil market and certain company-specific operating incidents, including the drop of the blowout preventer stack off the VALARIS DS-8. See "Note 13- Contingencies" for additional information. We do not believe that a material adverse effect has occurred, but there can be no assurance that the lenders will not assert a material adverse effect as a basis to deny further borrowing requests. 2024 Convertible Notes In December 2016, Ensco Jersey Finance Limited, a wholly-owned subsidiary of Valaris plc, issued $849.5 million aggregate principal amount of unsecured 2024 Convertible Notes in a private offering. The 2024 Convertible Notes are fully and unconditionally guaranteed, on a senior, unsecured basis, by Valaris plc and are exchangeable into cash, our Class A ordinary shares or a combination thereof, at our election. Interest on the 2024 Convertible Notes is payable semiannually on January 31 and July 31 of each year. The 2024 Convertible Notes will mature on January 31, 2024, unless exchanged, redeemed or repurchased in accordance with their terms prior to such date. Holders may exchange their 2024 Convertible Notes at their option any time prior to July 31, 2023 only under certain circumstances set forth in the indenture governing the 2024 Convertible Notes. On or after July 31, 2023, holders may exchange their 2024 Convertible Notes at any time. The exchange rate is 17.8336 shares per $1,000 principal amount of notes, representing an exchange price of $56.08 per share, and is subject to adjustment upon certain events. The 2024 Convertible Notes may not be redeemed by us except in the event of certain tax law changes. On April 15, 2020, we were notified by the NYSE that the average closing price of our Class A ordinary shares was below $1.00 per share over a period of 30 consecutive trading days, which is the minimum average share price required to maintain listing on NYSE. The Company has until late December 2020 to regain compliance. If our shares are delisted from the NYSE and not concurrently listed on Nasdaq, the holders of our 2024 Convertible Notes would have the right to require us to repurchase the notes at a price equal to the principal amount thereof plus accrued interest to the repurchase date. Such an accelerated repurchase, if required by the holders, could be in excess of the forecasted availability under the revolving credit facility and new financing facilities could be required, which we may not be able to put in place. Open Market Repurchases In early March 2020, we repurchased $12.8 million of our outstanding 4.70% Senior notes due 2021 on the open market for an aggregate purchase price of $9.7 million, excluding accrued interest, with cash on hand. As a result of the transaction, we recognized a pre-tax gain of $3.1 million, net of discounts in other, net, in the consolidated statement of operations.

On July 15, 2020, the Company, certain lenders party thereto, Citibank, N.A., as administrative agent (the “Agent”), and the other parties party thereto entered into a Second Amended and Restated Waiver to Fourth Amended and Restated Credit Agreement (the “Second A&R Waiver”), which amends, restates and replaces the Amended and Restated Waiver to Fourth Amended and Restated Credit Agreement, dated June 30, 2020 (the “A&R Waiver”), which was previously entered into by the Company, certain lenders party thereto, the Agent and the other parties thereto and which amended, restated and replaced the Waiver to Fourth Amended and Restated Credit Agreement, dated June 1,

The Initial Waiver was entered into under the Company’s Fourth Amended and Restated Credit Agreement dated May 7, 2013 (as amended, the “revolving credit facility”) to waive any resulting default or event of default attributed to any failure by the Company or any of its subsidiaries to make all or any part of their required interest payments due (i) on June 1, 2020 with respect to the Company’s 4.875% Senior Notes due 2022 (the “2022 Notes”) and 5.40% Senior Notes due 2042 (the “2042 Notes”) (collectively, the “June 1 Interest Payments”) and (ii) on June 15, 2020 with respect to the Company’s 7.375% Senior Notes due 2025 (the “2025 Notes”) (the “June 15 Interest Payments” and together with the June 1 Interest Payments, the “June Interest Payments”). The A&R Waiver was entered into by the parties thereto to continue to waive any default or event of default addressed in the A&R Waiver as well as to also waive any default or event of default under the revolving credit facility resulting from any cross-defaults (the “June 1 Cross-Defaults”) under the 2022 Notes, 2042 Notes, 2025 Notes, the 4.75% Senior Notes due 2024 (the "2024 Notes") and the 5.85% Senior Notes due 2044 (the "2044 Notes" and, collectively, the “Defaulted Notes”) in respect of the failure to pay the June 1 Interest Payments.

The Second A&R Waiver was entered into to continue to waive any default or event of default under the revolving credit facility attributed to (i) the failure to make the June Interest Payments and (ii) the June 1 Cross-Defaults. Additionally, the Second A&R Waiver waived any default or event of default under the revolving credit facility attributed to (i) any failure by the Company or any of its subsidiaries to make all or any part of their required interest payments due on (a) July 15, 2020, with respect to the Company’s 2024 Notes and 2044 Notes, (b) July 31, 2020, with respect to the Company’s 8.00%Senior Notes due 2024 and with respect to a subsidiary of the Company’s 3.00% Exchangeable Notes due 2024 and (c) August 1, 2020, with respect to the Company’s 7.75% Senior Notes due 2025, (ii) any resulting cross-defaults under the Defaulted Notes in respect of the failure to pay the June Interest Payments and (iii) an additional waiver relating to a vendor payment.

The Second A&R Waiver will remain in effect until the earliest of (i) August 3, 2020, (ii) termination or invalidity of the Forbearance Agreement (as defined below), the Forbearance Agreement ceasing to be in full force and effect or amendment of the Forbearance Agreement without consent of the requisite number of revolving credit facility lenders, (iii) acceleration by the holders of any of the Defaulted Notes in accordance with the terms of the Defaulted Notes and (iv) the date on which the aggregate amount of advances (excluding letter of credit obligations) outstanding under the revolving credit facility exceeds $630.0 million. The Second A&R Waiver includes customary representations and does not limit, impair or constitute a waiver of the rights and remedies of the lenders or the Agent, and except as expressly provided in the Second A&R Waiver and does not amend or affect the terms of the revolving credit facility.

On July 15, 2020, the Company entered into a Forbearance Agreement (the “Forbearance Agreement”) pursuant to that certain indenture dated July 21, 2009 between the Company and U.S. Bank National Association, as indenture trustee, under which the respective Defaulted Notes were issued with certain beneficial holders or investment managers or advisors for such beneficial holders (the “Supporting Holders”). At the time of entry into the Forbearance Agreement, the Supporting Holders held (i) approximately 44.0% of the outstanding 2022 Notes, (ii) approximately 74.2%of the outstanding 2024 Notes, (iii) approximately 65.3% of the outstanding 2025 Notes, (iv) approximately 68.9% of the outstanding 2042 Notes and (v) approximately 82.9%of the outstanding 2044 Notes. The parties previously entered into a Forbearance Agreement on June 30, 2020 that expired on July 15, 2020.

Pursuant to the Forbearance Agreement, the Supporting Holders have agreed to (i) forbear from the exercise of certain rights and remedies that they have under the related indenture or applicable law with respect to certain specified defaults and events of defaults (including cross-defaults as a result of an acceleration) and (ii) in the event that the applicable trustee or any holder or group of holders takes any action which results in an acceleration during the Forbearance Period (as defined below), to deliver written notice to the applicable trustee to rescind such acceleration and its consequences and take all other action in their power to cause such acceleration to be rescinded and annulled.

The Company and the Supporting Holders have agreed to continue this forbearance until the earlier of (i) August 3, 2020, (ii) the occurrence of any other default or event of default under the related indenture that is not cured within any applicable grace period, (iii) the acceleration of the Company’s obligations under the revolving credit facility, (iv) the termination or invalidity of the Second A&R Waiver, the Second A&R Waiver otherwise ceasing to be in full force and effect, or the Second A&R Waiver being amended, supplemented or otherwise modified in each case without the consent of the Supporting Holders, (v) the commencement of a case under title 11 of the United States Code or any similar reorganization, liquidation, insolvency or receivership proceeding by or against the Company or a subsidiary of the Company or (vi) the failure of the Company to timely comply with any term, condition or covenant set forth in the Forbearance Agreement (such period, the “Forbearance Period”).

We did not make interest payments due in June and July 2020 on the Defaulted Notes. The June 2020 missed interest payments represent current events of default under the Defaulted Notes. We have entered into the Forbearance Agreement pursuant to which certain holders of our senior notes have agreed to forbear from the exercise of certain rights and remedies that they have with respect to certain specified defaults and events of defaults (including cross-defaults). However, the events of default under the Defaulted Notes have not been waived and still exist, and the Forbearance Agreement will terminate automatically on August 3, 2020 and may be terminated upon certain other events that may occur prior to August 3, 2020. Accordingly, the amounts outstanding under the Defaulted Notes were classified as current in the accompanying Condensed Consolidated Balance Sheet as of June 30, 2020.

As a result of the Rowan Transaction, we acquired the following senior notes issued by Rowan Companies, Inc. ("RCI") and guaranteed by Rowan: (1) $201.4 million in aggregate principal amount of 7.875% unsecured senior notes due 2019, which have been repaid in full, (2) $620.8 million in aggregate principal amount of 4.875% unsecured senior notes due 2022, (3) $398.1 million in aggregate principal amount of 4.75% unsecured senior notes due 2024, (4) $500.0 million in aggregate principal amount of 7.375% unsecured senior notes due 2025, (5) $400.0 million in aggregate principal amount of 5.40% unsecured senior notes due 2042 and (6) $400.0 million in aggregate principal amount of 5.85% unsecured senior notes due 2044. On February 3, 2020, Rowan and RCI transferred substantially all their assets on a consolidated basis to Valaris plc, Valaris plc became the obligor on the notes and Rowan and RCI were relieved of their obligations under the notes and the related indenture.

As of June 30, 2020, we had $588.8 million outstanding under our credit facility, inclusive of $37.8 million in letters of credit, leaving $1.0 billion of undrawn capacity available. Our revolving credit facility requires compliance with covenants to maintain specified financial and guarantee coverage ratios, including a total debt to total capitalization ratio that is less than or equal to 60%. In the first six months of 2020, we incurred impairments of $3.6 billion, which contributed to an increase in the total debt to total capitalization ratio to 57.7% as of June 30, 2020. As of June 30, 2020, we were in compliance with our debt covenants due to the Second A&R Waiver. There is a significant level of uncertainty that we will remain in compliance with our credit facility covenants during the next twelve months. The full impact that the pandemic and the decline in oil prices and demand will have on our results of operations, financial condition, liquidity and cash flows is uncertain. If we were to violate the covenants of the revolving credit facility, further borrowings under the credit facility would not be permitted, absent a waiver in respect of the resulting event of default, and all outstanding borrowings could become immediately due and payable by action of lenders holding a majority of the commitments under the facility. Any such acceleration would trigger a cross-acceleration event of default with respect to approximately $2.1 billion outstanding under the Defaulted Notes.

The failure to make the interest payments due in June 2020 on the Defaulted Notes would have represented an event of default under the revolving credit facility if it had not been waived pursuant to the Second A&R Waiver. We have entered into the Second A&R Waiver pursuant to which the lenders under our revolving credit facility have waived certain defaults and events of default under the revolving credit facility, including in relation to the non-payment of interest under the Defaulted Notes. However, the Second A&R Waiver will terminate automatically on August 3, 2020 and may be terminated upon certain other events that may occur prior to August 3, 2020, including if advances

On or after July 31, 2023, holders may exchange their 2024 Convertible Notes at any time. The exchange rate is 17.8336 shares per $1,000 principal amount of notes, representing an exchange price of $56.08 per share, and is subject to adjustment upon certain events. The 2024 Convertible Notes may not be redeemed by us except in the event of certain tax law changes.

On April 15, 2020, we were notified by the NYSE that the average closing price of our Class A ordinary shares was below $1.00 per share over a period of 30 consecutive trading days, which is the minimum average share price required to maintain listing on NYSE. The Company has until late December 2020 to regain compliance. If our shares are delisted from the NYSE and not concurrently listed on Nasdaq, the holders of our 2024 Convertible Notes would have the right to require us to repurchase the notes at a price equal to the principal amount thereof plus accrued interest to the repurchase date. Such an accelerated repurchase, if required by the holders, could be in excess of the forecasted availability under the revolving credit facility and new financing facilities could be required, which we may not be able to put in place.

In early March 2020, we repurchased $12.8 million of our outstanding 4.70% Senior notes due 2021 on the open market for an aggregate purchase price of $9.7 million, excluding accrued interest, with cash on hand. As a result of the transaction, we recognized a pre-tax gain of $3.1 million, net of discounts in other, net, in the consolidated statement of operations.
