We are a leading provider of offshore contract drilling services to the international oil and gas industry.

Exclusive of two rigs under construction and one rig marked for retirement and classified as held-for-sale, we currently own and operate an offshore drilling rig fleet of 74 rigs, with drilling operations in almost every major offshore market across six continents.

Inclusive of our rigs under construction, our rig fleet includes 16 drillships, eight dynamically positioned semisubmersible rigs, two moored semisubmersible rigs and 50 jackup rigs, nine of which are leased to our 50/50 joint venture with Saudi Aramco.

We currently own an offshore drilling rig fleet of 61 rigs, with drilling operations in almost every major offshore market across five continents.

Our rig fleet includes 11 drillships, four dynamically positioned semisubmersible rigs, one moored semisubmersible rig, 45 jackup rigs and a 50% equity interest in ARO, our 50/50 joint venture with Saudi Aramco, which owns an additional seven rigs.

We operate the world's largest fleet amongst competitive rigs, including one of the newest ultra-deepwater fleets in the industry and a leading premium jackup fleet.

Our customers include many of the leading national and international oil companies, in addition to many independent operators.

We are among the most geographically diverse offshore drilling companies, with current operations spanning 24 countries on six continents.

The markets in which we operate include the Gulf of Mexico, Brazil, the Mediterranean, the North Sea, Norway, the Middle East, West Africa, Australia and Southeast Asia.

We are among the most geographically diverse offshore drilling companies, with current operations spanning nine countries on five continents.

Our customers bear substantially all of the costs of constructing the well and supporting drilling operations, as well as the economic risk relative to the success of the well.

Rowan Transaction

On October 7, 2018 , we entered into a transaction agreement (the "Transaction Agreement") with Rowan, and on April 11, 2019 (the "Transaction Date"), we completed our combination with Rowan pursuant to the Transaction Agreement (the "Rowan Transaction") and changed our name to Ensco Rowan plc.

On July 30, 2019 , we changed our name to Valaris plc.

Rowan's financial results are included in our consolidated results beginning on the Transaction Date.

As a result of the Rowan Transaction, Rowan shareholders received 2.750 Valaris Class A ordinary shares for each Rowan Class A ordinary share, representing a value of $43.67 per Rowan share based on a closing price of $15.88 per Valaris share on April 10, 2019 , the last trading day before the Transaction Date.

Total consideration delivered in the Rowan Transaction consisted of 88.3 million Valaris shares with an aggregate value of $1.4 billion .

All share and

per share data included in this report have been retroactively adjusted to reflect the Reverse Stock Split (as defined herein).

Prior to the Rowan Transaction, Rowan and Saudi Aramco formed a 50/50 joint venture to own, manage and operate drilling rigs offshore Saudi Arabia ("Saudi Aramco Rowan Offshore Drilling Company" or "ARO").

ARO currently owns a fleet of seven jackup rigs, leases another nine jackup rigs from us and has plans to purchase up to 20 newbuild jackup rigs over an approximate 10 year period.

In January 2020, ARO ordered the first two newbuild jackups scheduled for delivery in 2022.

The rigs we lease to ARO are done so through bareboat charter agreements whereby substantially all operating costs are incurred by ARO.

All nine jackup rigs leased to ARO and all seven ARO-owned jackup rigs are under long-term contracts with Saudi Aramco.

For additional information about our ARO joint venture, see Note 4 to our consolidated financial statements included in "Item 8.

Financial Statements and Supplementary Data."

The Rowan Transaction enhanced the market leadership of the combined company with a fleet of high-specification floaters and jackups and positions us well to meet increasing and evolving customer demand.

The increased scale, diversification and financial strength of the combined company provides us advantages to better serve our customers.

Exclusive of two older jackup rigs marked for retirement, Rowan’s offshore rig fleet at the Transaction Date consisted of four ultra-deepwater drillships and 19 jackup rigs.

Reverse Stock Split

Upon closing of the Rowan Transaction, we effected a consolidation (being a reverse stock split under English law) whereby every four existing Valaris Class A ordinary shares, each with a nominal value of $0.10 , were consolidated into one Class A ordinary share, each with a nominal value of $0.40 (the “Reverse Stock Split”).

Our shares began trading on a reverse stock split-adjusted basis on April 11, 2019 .

All share and per share data included in this report have been retroactively adjusted to reflect the Reverse Stock Split.

Operating results in the offshore contract drilling industry are highly cyclical and are directly related to the demand for drilling rigs and the available supply of drilling rigs.

Operating results in the offshore contract drilling industry are highly cyclical and are directly related to the demand for and the available supply of drilling rigs.

Low demand and excess supply can independently affect day rates and utilization of drilling rigs.

1 unchanged sentence

While the cost of moving a rig may cause the balance of supply and demand to vary somewhat between regions, significant variations between regions are generally of a short-term nature due to rig mobility.

Drilling Rig Demand

The decline in oil prices from 2014 highs led to a significant reduction in global demand for offshore drilling services.

Customers significantly reduced their capital spending budgets, including the cancellation or deferral of existing programs, resulting in fewer contracting opportunities for offshore drilling rigs.

Declines in capital spending levels, together with the oversupply of rigs from newbuild deliveries, resulted in significantly reduced day rates and utilization that led to one of the most severe downturns in the industry's history.

More recently, oil prices have increased meaningfully from the decade lows reached during 2016, with Brent crude averaging nearly $55 per barrel in 2017 and more than $70 through most of 2018, leading to signs of a gradual recovery in demand for offshore drilling services.

However, macroeconomic and geopolitical headwinds triggered a decline in Brent crude prices in late 2018, from more than $85 per barrel to approximately $50 per barrel.

In 2019, oil prices experienced a gradual recovery from this decline with Brent crude prices averaging approximately $64 per barrel before falling near $55 per barrel in early 2020.

While this market volatility will likely continue over the near-term, we expect long-term oil prices to remain at levels sufficient to support a continued gradual recovery in demand for offshore drilling services.

However, uncertainty remains regarding global trade and other geopolitical tensions in the Middle East and China and their resulting impact on the global economy.

Adverse changes in the macro-economic environment resulting from trade

discussions, geopolitical events or other factors, including the impact of the coronavirus on global trade, could have a significant adverse impact on global economic growth and ultimately the demand for our offshore drilling services.

We continue to observe improvements in the shallow-water market, particularly with respect to higher-specification rigs, as higher levels of customer demand and rig retirements have led to gradually increasing jackup utilization over the past year.

Moreover, global floater utilization has increased as compared to a year ago due to a higher number of contracted rigs and lower global supply resulting from rig retirements.

However, the floater recovery has lagged the jackup recovery as average contract durations remain relatively short-term and pricing improvements to date have been modest.

Despite the increase in customer activity, contract awards remain subject to an extremely competitive bidding process, and the corresponding pressure on operating day rates in recent periods has resulted in low margin contracts, particularly for floaters.

Therefore, our results from operations may continue to decline over the near-term as current contracts with above-market rates expire and new contracts are executed at lower rates.

We believe further improvements in demand coupled with a reduction in rig supply are necessary to improve the commercial landscape for day rates.

Drilling Rig Supply

Drilling rig supply continues to exceed drilling rig demand for both floaters and jackups.

However, the decline in customer capital expenditure budgets over the past several years has led to a lack of contracting opportunities resulting in meaningful global fleet attrition.

Since the beginning of the downturn, drilling contractors have retired approximately 135 floaters and 100 jackups.

As demand for offshore drilling has slowly begun to improve, newer more capable rigs have been the first to obtain new contract awards, increasing the likelihood that older, less capable rigs do not return to the global active fleet.

Approximately 20 floaters older than 30 years are idle, 10 additional floaters older than 30 years have contracts expiring by the end of 2020 without follow-on work and a further five floaters aged between 15 and 30 years have been idle for more than two years.

Operating costs associated with keeping these rigs idle as well as expenditures required to re-certify these aging rigs may prove cost prohibitive.

Drilling contractors will likely elect to scrap or cold-stack some or all of these rigs.

Approximately 90 jackups older than 30 years are idle, and 60 jackups that are 30 years or older have contracts expiring by the end of 2020 without follow-on work.

Expenditures required to re-certify these aging rigs may prove cost prohibitive and drilling contractors may instead elect to scrap or cold-stack these rigs.

We expect jackup scrapping and cold-stacking to continue during 2020 .

There are 26 newbuild drillships and semisubmersibles reported to be under construction, of which 16 are scheduled to be delivered before the end of 2020 .

Following several years of market volatility beginning with oil price declines in 2014, as we entered 2020, we expected that volatility to continue over the near-term with the expectation that long-term oil prices would remain at levels sufficient to support a continued gradual recovery in the demand for offshore drilling services.

We were focused on opportunities to put our rigs to work, manage liquidity, extend our financial runway, and reduce debt as we sought to navigate the extended market downturn and improve our balance sheet.

Recognizing our ability to maintain a sufficient level of liquidity to meet our financial obligations depended upon our future performance, which is subject to general economic conditions, industry cycles and financial, business and other factors affecting our operations, many of which are beyond our control, we had significant financial flexibility within our capital structure to support our liability management efforts.

However, starting in early 2020, the COVID-19 pandemic and the response thereto negatively impacted the macro-economic environment and global economy.

Global oil demand fell sharply at the same time global oil supply increased as a result of certain oil producers competing for market share, leading to a supply glut.

As a consequence, the price of Brent crude oil fell

from around $60 per barrel at year-end 2019 to around $20 per barrel in mid-April 2020.

In response to dramatically reduced oil price expectations for the near term, our customers reviewed, and in most cases lowered significantly, their capital expenditure plans in light of revised pricing expectations.

This caused our customers to cancel or shorten the duration of many of our 2020 drilling contracts, cancel future drilling programs and seek pricing and other contract concessions, which led to material operating losses and liquidity constraints for us.

While there has been some recent improvement to Brent crude oil prices, to approximately $65 per barrel in February 2021, there is still a significant amount of uncertainty around the sustainability of the improvement in oil prices to support a recovery in demand for offshore drilling services.

Additionally, the full impact that the pandemic and the decline in oil prices will have on our results of operations, financial condition, liquidity and cash flows is uncertain due to numerous factors, including the duration and severity of the outbreak, the effectiveness of the ongoing vaccine rollout, the duration of the oil price and demand decline, and the extent of disruptions to our operations.

To date, the COVID-19 pandemic has resulted in only limited operational downtime.

Our rigs have had to shut down operations while crews are tested and incremental sanitation protocols are implemented and while crew changes have been restricted as replacement crews are quarantined.

We continue to incur additional personnel, housing and logistics costs in order to mitigate the potential impacts of COVID-19 to our operations.

In limited instances, we have been reimbursed for these costs by our customers.

Our operations and business may be subject to further economic disruptions as a result of the spread of COVID-19 among our workforce, the extension or imposition of further public health measures affecting supply chain and logistics, and the impact of the pandemic on key customers, suppliers, and other counterparties.

There can be no assurance that these, or other issues caused by the COVID-19 pandemic, will not materially affect our ability to operate our rigs in the future.

We expect that these challenges will continue for drilling contractors as customers wait to gain additional clarity on commodity pricing and seek to reduce costs in the near-term by attempting to renegotiate existing contract terms.

We believe the current market and macro-economic conditions will create a challenging contracting environment through 2021 and into 2022 and potentially beyond.

The combined effects of the global COVID-19 pandemic, the significant decline in the demand for oil and the substantial surplus in the supply of oil have resulted in significantly reduced demand and day rates for offshore drilling provided by the Company and increased uncertainty regarding long-term market conditions.

These recent events have had a significant adverse impact on our current and expected liquidity position and financial runway and led to the filing of the Chapter 11 Cases.

While we have and are continuing to pursue a variety of cost-cutting measures such as further reductions in corporate overhead and discretionary expenditures, reductions in capital expenditures and an increased focus on operational efficiencies, we determined that based on our significant level of indebtedness and the circumstances described above that a comprehensive restructuring of our indebtedness was needed to improve our financial position.

As more fully described in “ Note 2 – Chapter 11 Proceedings and Ability to Continue as a Going Concern” to our consolidated financial statements included in "Item 8.

Financial Statements and Supplementary Data", the Company will undergo a financial restructuring that is intended to reduce debt levels substantially, support continued operations during the current lower demand environment and provide a robust financial platform to take advantage of market recovery over the long-term.

For additional information related to drilling rig supply and demand, see "Business Environment" below.

Chapter 11 Proceedings and Ability to Continue as a Going Concern

On August 19, 2020 (the “Petition Date”), the Debtors filed voluntary petitions for reorganization under chapter 11 of the Bankruptcy Code in the Bankruptcy Court.

As part of the chapter 11 cases under the caption In re Valaris plc, et al., Case No.

20-34114 (MI) (the “Chapter 11 Cases”), the Debtors were granted “first-day” relief which enabled the Company to continue operating without interruption or disruption to its relationships with its customers and vendors or its high-quality service delivery.

In particular, employee pay and benefits are expected to continue without interruption.

On August 18, 2020, the Debtors entered into the Original RSA with the Consenting Noteholders.

On February 5, 2021, the Debtors entered into the Amended RSA with the Consenting Lenders and Consenting Noteholders, which contemplates that the Company will implement the restructuring through the Chapter 11 Cases pursuant to a plan of reorganization and the various related transactions set forth in or contemplated by the Amended RSA.

Holders of approximately 100% of the total commitments outstanding under our revolving credit facility and holders of approximately 72% of the aggregate amount of our Senior Notes outstanding are party to the Amended RSA.

Pursuant to the Amended RSA the holders of the Company's Senior Notes (as defined below) will receive their pro rata share of (1) approximately 39% of new common stock issued after consummation of the restructuring (the “New Equity”) and (2) approximately 97.6% of the subscription rights to participate in the rights offering (the "Rights Offering") through which the Company will offer $550 million of new first lien secured notes (the "New Secured Notes"), which includes the Backstop Premium (as defined below).

Additionally, holders of the Senior Notes who participate in the Rights Offering will receive their pro rata share of approximately 29.3% of the New Equity pursuant to the Rights Offering, together with the RCF Lenders (as defined below) who will receive their pro rata share of approximately 0.7% of the New Equity, and senior noteholders who agreed to backstop the Rights Offering will receive their pro rata share of approximately 2.63% of the New Equity, together with 0.07% of the New Equity reserved for RCF Lenders and approximately $48.8 million in New Secured Notes reserved for the holders of the Senior Notes and approximately $1.2 million in New Secured Notes reserved for the RCF Lenders (the "Backstop Premium").

Senior noteholders with respect to certain notes would receive an aggregate cash payment of $26 million in connection with settlement of certain alleged claims against the Company.

A reorganization pursuant to the terms of the Amended RSA provided lenders under the revolving credit facility (“RCF Lenders”) with an option to select between two alternative treatments:

(1) the ability to participate on a pro rata basis in up to 14% of the Rights Offering plus a recovery of up to 30.8% of the New Equity and up to $45 million in cash, or (2) a pro rata recovery of up to 27.8% of the New Equity and up to $116.2 million in cash.

Following the results of that election, the two RCF Lenders who chose to participate in the Rights Offering will receive their pro rata share of (1) approximately 5.3% of the New Equity, (2) approximately 2.4% of the New Secured Notes (and associated New Equity), (3) approximately $7.8 million in cash, and (4) their pro rata share of the Backstop Premium.

The RCF Lenders who entered into the Amended RSA and elected not to participate in the Rights Offering will receive their pro rata share of (1) approximately 23.0% of the New Equity, and (2) approximately $96.1 million in cash.

The Amended RSA provides that holders of general unsecured claims will receive payment in full or reinstatement pursuant to the Bankruptcy Code (excluding claims against the entities party to, or guaranteeing, the new build contracts to be rejected by the Company, which shall receive their liquidation value unless otherwise agreed).

Moreover, if holders of equity interests vote as a class in support of the restructuring, they will each receive their pro rata share of 7-year warrants to purchase up to 7% of New Equity (subject to dilution), with a strike price set at a price per share equal to the value at which the senior noteholders would receive a 100% recovery on their claims including accrued interest up to the Petition Date, as applicable.

Lastly, to the extent amounts are borrowed, lenders under the DIP Facility (as defined below) will receive payment in full in cash, unless otherwise agreed and certain other fees owed to the DIP Lenders.

The Amended RSA contains certain covenants on the part of Valaris and the Consenting Creditors, including commitments by the Consenting Creditors to vote in favor of a plan of reorganization and commitments of Valaris and the Consenting Creditors to negotiate in good faith to finalize the documents and agreements governing the restructuring.

The Amended RSA also provides for certain conditions to the obligations of the parties and for termination upon the occurrence of certain events, including without limitation, the failure to achieve certain milestones and certain breaches by the parties under the Amended RSA.

Subject to certain exceptions, under the Bankruptcy Code, the filing of the Chapter 11 Cases automatically enjoined, or stayed, the continuation of most judicial or administrative proceedings or filing of other actions against the Debtors or their property to recover, collect or secure a claim arising prior to the date of the Chapter 11 Cases.

Notwithstanding the general applicability of the automatic stay described above, governmental authorities may determine to continue actions brought under their regulatory powers.

Although Valaris intends to pursue the restructuring in accordance with the terms set forth in the Amended RSA, there can be no assurance that Valaris will be successful in completing a restructuring or any other similar transaction on the terms set forth in the Amended RSA, on different terms or at all.

Among other things, the Amended RSA includes an outside date milestone requiring the Company’s emergence from chapter 11 by no later than June 15, 2021 (subject to a potential 60-day extension pursuant to the terms of the Amended RSA).

Other Chapter 11 Financial Disclosures

Pre-petition Charges

On August 18, 2020, the Company entered into the Backstop Commitment Agreement with certain backstop parties.

In connection with this agreement, the Debtors paid a commitment fee of $20.0 million, in cash prior to the Petition Date.

We have reported the backstop commitment fee and legal and other professional advisor fees incurred in relation to the Chapter 11 Cases, but prior to the Petition Date, as General and administrative expenses in our Consolidated Statement of Operations for the year ended December 31, 2020 in the amount of $64.7 million.

Liquidity and Debt Maturities

As discussed in " Note 2 - Chapter 11 Proceedings and Ability to Continue as a Going Concern" to our consolidated financial statements included in "Item 8.

Financial Statements and Supplementary Data", we have filed the Chapter 11 Cases to effect a comprehensive restructuring of our indebtedness.

The commencement of the Chapter 11 Cases on August 19, 2020, constituted an event of default under our Senior Notes and revolving credit facility.

Any efforts to enforce payment obligations under the Senior Notes, including any rights to require the repurchase by the Company of the 2024 Convertible Notes upon the NYSE delisting of the Class A ordinary shares, and revolving credit facility are automatically stayed as a result of the filing of the Chapter 11 Cases.

The $6.5 billion aggregate principal amount of Senior Notes outstanding as well as $581.0 million outstanding borrowings under our revolving credit facility as of the Petition Date are classified as Liabilities Subject to Compromise in our Consolidated Balance Sheet as of December 31, 2020.

On September 25, 2020, following approval by the Bankruptcy Court, we entered into a senior secured superpriority debtor-in-possession term loan credit agreement (the “DIP Credit Agreement”), by and among the Company and certain wholly owned subsidiaries of the Company, as borrowers, the lenders party thereto and Wilmington Savings Fund Society, FSB, as administrative agent and security trustee, in an aggregate amount not to exceed $500.0 million (the “DIP Facility”) to provide liquidity during the pendency of the Chapter 11 Cases.

February 5, 2021, we entered into an amendment to the Backstop Commitment Agreement, which we expect to provide exit financing in the form of a fully backstopped rights offering to senior noteholders and the RCF Lenders for $550 million of New Secured Notes.

We expect the DIP Facility will provide sufficient liquidity for us during the pendency of the Chapter 11 Cases.

Additionally, we expect the exit financing will provide the necessary liquidity to support ongoing operations and working capital needs.

As of December 31, 2020, we had $325.8 million in cash and there were no borrowings outstanding under the DIP Credit Agreement.

For the duration of the Chapter 11 Cases, our operations and our ability to develop and execute our business plan are subject to a high degree of risk and uncertainty associated with the Chapter 11 Cases.

The outcome of the Chapter 11 Cases is dependent upon factors that are outside of our control, including actions of the Bankruptcy Court and our creditors.

There can be no assurance that we will confirm and consummate a plan of reorganization as contemplated by the Amended RSA or complete another plan of reorganization with respect to the Chapter 11 Cases and as such, there is substantial doubt about our ability to continue as a going concern.

Further, we have concluded that management’s plans do not alleviate the substantial doubt about our ability to continue as a going concern brought about by the significant risks and uncertainties related to our liquidity and Chapter 11 Cases for a period of one year after the date that the financial statements are issued.

See "Liquidity and Capital Resources" below and " Note 2 – Chapter 11 Proceedings and Ability to Continue as a Going Concern” to our consolidated financial statements included in "Item 8.

Financial Statements and Supplementary Data" for additional information.

As of December 31, 2020, our backlog was $1.2 billion as compared to $2.5 billion as of December 31, 2019.

Our floater backlog declined $641.6 million and our jackup backlog declined $421.7 million.

The decrease in our backlog was due to customer contract cancellations, customer concessions and revenues realized, partially offset by the addition of backlog from new contract awards and contract extensions.

Our other segment backlog declined $184.2 million due to contract concessions and revenues realized.

Our backlog excludes ARO's backlog, but includes backlog from our rigs leased to ARO at the contractual rates.

Contract rates with ARO are subject to adjustment resulting from the shareholder agreement.

See " Note 5 - Equity Method Investment in ARO" to our consolidated financial statements included in "Item 8.

Financial Statements and Supplementary Data" for additional information.

As revenues are realized and if we experience further customer contract cancellations, we may continue to experience declines in backlog, which would result in a decline in revenues and operating cash flows over the near-term.

Contract backlog was adjusted for drilling contracts signed, terminated or concessions granted after each respective balance sheet date but prior to filing each annual report on March 2, 2021 and February 21, 2020, respectively.

BUSINESS ENVIRONMENT

The floater contracting environment remains challenging due to limited demand and excess supply.

Floater demand has declined significantly following the decline in commodity prices in 2014 which caused our customers to reduce capital expenditures, particularly for capital-intensive, long-lead deepwater projects, resulting in the cancellation and delay of drilling programs.

Floater demand declined materially in March and April 2020, as our customers reduced capital expenditures particularly for capital-intensive, long-lead deepwater projects in the wake of oil price declines from around $60 per barrel at year-end 2019 to around $20 per barrel in mid-April 2020.

The decline in demand has resulted in the cancellation and delay of drilling programs and the termination of drilling contracts.

During 2020, we received notices of termination, requests for concessions, cancellation and/or deferral of drilling programs by operators and we may receive additional requests for concessions, termination and/or deferral notices during the pendency of the current market environment.

During the first quarter of 2020, VALARIS DS-12 was awarded a one-well contract that commenced in February 2020.

VALARIS MS-1 was awarded a three-well contract that is expected to commence in the second quarter of 2021 and has an estimated duration of 155 days.

VALARIS 8505 was awarded a one-well contract that was expected to commence in mid-November 2020, but is now expected to commence in June 2021 with an estimated duration of 80 days.

In March 2020, VALARIS DS-8 experienced a non-drilling incident while operating offshore Angola, resulting in the blowout preventer (BOP) stack being disconnected from the riser while the rig was moving between well locations.

The BOP stack, which we later recovered, dropped to the seabed floor, clear of any subsea structures.

No injuries, environmental pollution or third-party damage resulted from the BOP stack being disconnected.

As a result of the incident, the operator terminated the contract.

The termination resulted in a decline in our contracted revenue backlog of approximately $150 million.

We carried loss of hire insurance covering $602,500 per day, after a 45-day deductible waiting period, through the end of the contract in November 2020.

The waiting period expired on April 22, 2020.

We received loss of hire insurance recoveries of $118.1 million , which represents the total amount owed to us under the applicable insurance policy.

The recovery was recognized and recorded in Other operating income on our Consolidated Statements of Operations.

During the second quarter of 2020, the VALARIS DS-7 contract for operations offshore Ghana was terminated.

Additionally, contracts awarded in the first quarter of 2020 for VALARIS DS-7 operations offshore Senegal/Mauritania, VALARIS DS-9 operations offshore Brazil and VALARIS MS-1 contract operations offshore Australia were terminated.

Further, the VALARIS DPS-1 contract was terminated in June, earlier than the previously scheduled end date of September 2021, and the VALARIS DS-10, VALARIS DS-15 and VALARIS 8505 operated on reduced day rates for various periods during 2020.

The VALARIS 5004 operated on a reduced day rate from mid-March to mid-April of 2020, at which point the contract was terminated.

During the third quarter of 2020, floater contracting remained challenging and no significant new contracts were executed.

In the fourth quarter of 2020, we extended the VALARIS DS-10 and VALARIS DS-18 contracts for an estimated 90 days and 60 days, respectively.

In January 2021, we extended the VALARIS DS-12 contract for an estimated 100 days.

Our backlog for our floater segment was $205.7 million and $847.3 million as of December 31, 2020 and December 31, 2019, respectively.

The VALARIS 6002 was sold in January 2020 resulting in an insignificant pre-tax gain.

Additionally, the VALARIS 5004 was sold in April 2020 resulting in an insignificant pre-tax loss.

During the second quarter of 2020, we began marketing VALARIS 8500, VALARIS 8501, VALARIS 8502, VALARIS DS-3, VALARIS DS-5 and VALARIS DS-6 and classified these rigs as held-for-sale, resulting in an impairment of approximately $14.6 million as the net book value exceeded the fair value less costs to sell.

During the third quarter of 2020, we sold VALARIS 8500, VALARIS 8501 and VALARIS 8502 for a total pre-tax gain of $7.7 million, we sold the VALARIS DS-3, VALARIS DS-5 and VALARIS DS-6 for an insignificant pre-tax loss and we classified VALARIS 8504 as held-for-sale.

The net book value of VALARIS 8504 did not exceed the fair value less costs to sell;

therefore, we did not recognize an impairment upon classifying this rig as held-for-sale.

The rig was subsequently sold in October 2020.

There are approximately 25 newbuild drillships and semisubmersible rigs reported to be under construction, of which approximately 10 are scheduled to be delivered before the end of 2021.

Most newbuild floaters are uncontracted.

Several newbuild deliveries have been delayed into future years, and we expect that more uncontracted newbuilds will be delayed or cancelled.

There are 51 newbuild jackups reported to be under construction, of which 41 are scheduled to be delivered before the end of 2020 .

Drilling contractors have retired approximately 160 floaters since the beginning of 2014.

Approximately 15 floaters older than 30 years of age are currently idle, approximately ten additional floaters older than 30 years of age have contracts that will expire by the end of 2021 without follow-on work.

Additional rigs are expected to become idle as a result of market conditions.

Operating costs associated with keeping these rigs idle as well as expenditures required to re-certify these aging rigs may prove cost prohibitive.

Drilling contractors will likely elect to scrap or cold-stack some or all of these rigs.

Improvements in demand and/or reductions in supply will be necessary before meaningful increases in utilization and day rates are realized.

During 2020, demand for jackups has declined in light of increased market uncertainty.

We have received notices of termination, requests for concessions, cancellation and/or deferral of drilling programs by operators, and we may receive additional requests for concessions, termination and/or deferral notices during the pendency of the current market environment.

During the first quarter of 2020, we executed a three-well contract for VALARIS JU-118 that commenced in mid-March 2020 with an estimated duration of 425 days.

Additionally, we executed a two-well contract for VALARIS JU-144 that commenced in May 2020 with an estimated duration of 300 days.

The previously disclosed contract for the VALARIS JU-144 that was expected to commence in September 2020 was transferred to the VALARIS JU-102 and was subsequently delayed to September 2021, with VALARIS JU-102 being put on a standby rate until the new commencement date.

VALARIS JU-87 was awarded a one-well contract that commenced in March 2020 with an estimated duration of 30 days and an extension to May 2020 for another well with an estimated duration of 30 days.

During the first quarter of 2020, the VALARIS JU-109 contract was terminated.

During the second quarter of 2020, the VALARIS JU-84 contract was terminated and we negotiated a day rate reduction for VALARIS JU-290 to be suspended at a reduced rate from September 2020 to February 2021.

In April 2020, there were various negotiated customer contract concessions, including day rate reductions.

VALARIS JU-120 was suspended at a reduced day rate from late-April 2020 to September 2020 and VALARIS JU-72 was suspended at a reduced day rate from April 2020 to August 2020.

VALARIS JU-92 was previously expected to be suspended at a reduced day rate from mid-May 2020 to late-September 2020, but has continued to operate at full day rate.

VALARIS JU-249 ended its contract in April 2020 and VALARIS JU-100 ended its contract in late-April 2020, in both cases, earlier than expected.

During the second quarter of 2020, we executed short-term contracts for VALARIS JU-102 and VALARIS JU-87 that commenced in June 2020 and May 2020, respectively.

We were also awarded a two-well extension for VALARIS JU-291 with an expected duration of approximately 230 days from January 2021 to August 2021.

We executed a four-year contract for VALARIS JU-104 expected to commence in September 2020, which was subsequently terminated during the third quarter of 2020.

Additionally, we extended the VALARIS JU-67 contract 210 days from May 2020 to December 2020.

During the third quarter of 2020, VALARIS JU-54 and VALARIS JU-76 were put on a reduced standby rate until late 2020.

Following the reduced standby rate period, VALARIS JU-54 will be operating at an agreed upon reduced day rate until the end of 2021 and VALARIS JU-76 will be suspended until it resumes operation in March 2021 at an agreed upon reduced day rate until the end of 2021.

During the third quarter, we also negotiated reduced rates for VALARIS 108, VALARIS 140 and VALARIS 141.

The reduced rates are effective beginning the second quarter of 2020 through the end of their contract terms in November 2021, June 2021 and August 2021, respectively.

Additionally, we executed a one year contract extension for VALARIS 110 that commenced in October 2020 and executed a short-term contract for VALARIS 115 that commenced in February 2021.

During the fourth quarter of 2020, we executed an eight-well contract extension for VALARIS JU-292 Additionally, we extended the VALARIS JU-67 contract for approximately 190 days from December 2020 to June 2021.

In January and February 2021, we executed a two-year contract for VALARIS JU-121, an approximate one-year contract for VALARIS JU-247, and the VALARIS JU-122 contract was extended for approximately 95 days from April 2021 to July 2021.

Our backlog for our jackup segment was $859.5 million and $1,281.2 million as of December 31, 2020 and December 31, 2019, respectively.

The VALARIS JU-68 was sold in January 2020, resulting in an insignificant pre-tax gain.

Additionally, VALARIS JU-70 and VALARIS JU-71 were sold in June 2020 resulting in insignificant pre-tax losses.

During the second quarter of 2020, we classified VALARIS JU-105 as held-for-sale, resulting in an insignificant impairment as the net book value exceeded the fair value less cost to sell.

During the third quarter of 2020, we sold VALARIS JU-87 and VALARIS JU-105 for an insignificant pre-tax gain and we classified VALARIS JU-84 and VALARIS JU-88 as held-for-sale.

The net book values of VALARIS JU-84 and VALARIS JU-88 did not exceed the fair values less costs to sell, therefore, we did not recognize an impairment upon classifying these rigs as held-for-sale.

These rigs were subsequently sold in October 2020.

There are approximately 40 newbuild jackup rigs reported to be under construction, of which 20 are scheduled to be delivered before the end of 2021.

Most newbuild jackups are uncontracted.

1 unchanged sentence

We expect that scheduled jackup deliveries will continue to be delayed until more rigs are contracted.

Liquidity, Debt Maturities and Backlog

We proactively manage our capital structure in an effort to most effectively execute our strategic priorities and maximize value for shareholders.

In support of these objectives, we are focused on our liquidity, debt levels and maturity profile and cost of capital.

Over the past several years we have executed a number of financing transactions to improve our financial statement position and manage our debt maturities, including the July 2019 tender offers discussed below.

Based on our balance sheet, our contractual backlog and $1.6 billion available under our credit facility, we expect to fund our anticipated 2020 liquidity needs, including negative operating cash flows, debt service and other contractual obligations, anticipated capital expenditures, as well as working capital requirements, from cash and short-term investments and funds borrowed under our credit facility or other future financing arrangements, including available shipyard financing options for our two drillships under construction.

Our credit facility is an integral part of our financial flexibility and liquidity.

We also may rely on the issuance of debt and/or equity securities in the future to supplement our liquidity needs.

In addition, we may seek to extend our maturities and reduce the overall principal amount of our debt through exchange offers or other liability management transactions.

We have significant financial flexibility within our capital structure, including the ability to issue debt that would be structurally senior to our currently outstanding debt, on both an unsecured and secured basis, subject to restrictions contained in our existing debt arrangements.

Our liability management efforts, if undertaken, may be unsuccessful or may not improve our financial position to the extent anticipated.

Our ability to maintain a sufficient level of liquidity to meet our financial obligations will also be dependent upon our future performance, which will be subject to general economic conditions, industry cycles and financial, business and other factors affecting our operations, many of which are beyond our control.

For example, if we experience further deterioration in demand for offshore drilling, our ability to maintain a sufficient level of liquidity could be materially and adversely impacted, which could have a material adverse impact on our business, financial condition, results of operations, cash flows and our ability to repay or refinance our debt.

Cash and Debt

As of December 31, 2019 , we had $6.5 billion in total principal debt outstanding, representing 41.2% of our total capitalization.

We also had $97.2 million in cash and $1.6 billion undrawn capacity under our credit facility, which expires in September 2022.

In December 2019, we received $200.0 million in cash resulting from the settlement of a dispute with Samsung Heavy Industries.

See Note 13 to our consolidated financial statements included in "Item 8.

Financial Statements and Supplementary Data."

Effective upon closing of the Rowan Transaction, we amended our credit facility to, among other changes, increase the borrowing capacity.

Previously, our credit facility had a borrowing capacity of $2.0 billion through September 2019 that declined to $1.3 billion through September 2020 and $1.2 billion through September 2022.

Subsequent to the amendment our borrowing capacity is $1.6 billion through September 2022.

The credit agreement governing the credit facility includes an accordion feature allowing us to increase the future commitments by up to an aggregate amount not to exceed $250.0 million .

As a result of the Rowan Transaction, we acquired the following debt:

(1) $201.4 million in aggregate principal amount of 7.875% unsecured senior notes , which was repaid at maturity in August 2019, (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 5.4% unsecured senior notes due 2042 and (6) $400.0 million in aggregate principal amount of 5.85% unsecured senior notes due 2044 .

Upon closing of the Rowan Transaction, we terminated Rowan's outstanding credit facilities.

On June 25, 2019, we commenced cash tender offers for certain senior notes issued by us, Ensco International Incorporated and Rowan Companies, Inc., our wholly-owned subsidiaries.

The tender offers expired on July 23, 2019, and we repurchased $951.8 million aggregate principal amount of notes for a total purchase price of approximately $724.1 million , plus accrued interest.

As of December 31, 2019 , our principal debt maturities include $122.9 million in 2020, $113.5 million in 2021, $620.8 million in 2022 and $1.8 billion in 2024.

As of December 31, 2019 , our backlog was $2.5 billion as compared to $2.2 billion as of December 31, 2018 .

Our floater backlog declined $94.2 million and our jackup backlog increased $210.2 million .

These changes resulted from the addition of backlog from the Rowan Transaction, new contract awards and contract extensions offset by revenues realized during the period.

Our other segment backlog increased $154.4 million due to the addition of backlog from the Rowan Transaction related to the rigs leased to ARO.

Contract backlog includes the impact of drilling contracts signed or terminated after each respective balance sheet date but prior to filing our annual reports on February 21, 2020 and February 28, 2019 , respectively.

BUSINESS ENVIRONMENT

The floater contracting environment remains challenging due to limited demand and excess newbuild supply.

During the past year, we have observed increased tendering activity that may translate into marginal improvements in near-term utilization;

however, further improvements in demand and/or reductions in supply will be necessary before meaningful increases in utilization and day rates are realized.

During the first quarter of 2019, we executed a four-well contract for VALARIS DS-9 that commenced offshore Brazil in June 2019 and a six-month contract for VALARIS DS-7 that commenced offshore Egypt in April 2019.

Additionally, we executed a two-well contract for VALARIS DPS-1 that is expected to commence in March 2020 and a four-well contract for VALARIS 8503 that commenced in July 2019.

During the second quarter of 2019, we executed a one-well contract for VALARIS DS-18 in the U.S.

The VALARIS 6002 was subsequently sold in January 2020 resulting in an insignificant pre-tax gain.

Demand for jackups has improved with increased contracting activity observed over the past year, leading to slight improvements in day rates.

During the first quarter of 2019, we executed a nine-well contract for VALARIS JU-100 that commenced in November 2019.

As a result, a previously disclosed contract for VALARIS JU-100 has been fulfilled by VALARIS JU-248.

Additionally, we executed a three-well contract for VALARIS JU-121 that commenced in April 2019 and three-well and one-well contracts for VALARIS JU-72 and VALARIS JU-68, respectively, that commenced during May 2019.

We also executed short-term contract extensions for VALARIS JU-101 and VALARIS JU-96.

With respect to the Rowan jackups, a six-month contract extension with a two-month option was executed for VALARIS JU-248 during the first quarter.

Additionally, short-term contracts were executed for VALARIS JU-292, VALARIS JU-290 and VALARIS JU-144.

The VALARIS JU-290 and VALARIS JU-292 contracts include four additional one-well priced options and two short-term option periods, respectively.

During the second quarter of 2019, we executed a two-year contract for VALARIS JU-120, a two-well contract for VALARIS JU-122, a forty-well P&A contract for VALARIS JU-72, a five-month contract for VALARIS JU-107, two one-well contracts for VALARIS JU-102 and a one-well contract for VALARIS JU-101.

Additionally, we executed a two-year extension for VALARIS JU-109, a seven-month extension for VALARIS JU-104, a six-month extension for VALARIS JU-247, a three-month extension for VALARIS JU-96 and one-well extensions for VALARIS JU-118 and VALARIS JU-144.

During the second quarter of 2019, we scrapped ENSCO 97 and the Gorilla IV and recognized an insignificant pre-tax gain.

During the third quarter of 2019, we executed a four-well contract for VALARIS JU-248, an accommodation contract for VALARIS JU-290, a one-well contract for VALARIS JU-107 and a one-well contract for VALARIS JU-87 that commenced in September.

We also extended the contracts for VALARIS JU-291 by two-wells, VALARIS JU-247 by approximately eight months and received short-term extensions for VALARIS JU-88, VALARIS JU-115, VALARIS JU-117, VALARIS JU-123 and VALARIS JU-248.

During the fourth quarter of 2019, we executed a 200-day contract for VALARIS JU-249 and a 21-well contract for VALARIS JU-87, both of which commenced in November 2019, and a one-well contract for VALARIS JU-75 that commenced in December 2019.

We also began marketing the VALARIS JU-68 and VALARIS JU-70 and classified the rigs as held-for-sale on our December 31, 2019 consolidated balance sheet.

We recognized a pre-tax impairment charge of $10.2 million on the VALARIS JU-70.

The VALARIS JU-68 was subsequently sold in January 2020 resulting in an insignificant pre-tax loss.

In July 2019, a well being drilled offshore Indonesia by one of our jackup rigs experienced a well-control event requiring the cessation of drilling activities.

The operator could seek to terminate the contract under certain circumstances.

If this drilling contract were to be terminated for cause, it would result in an approximate $8.5 million decrease in our backlog as of December 31, 2019 .

See Note 13 to our consolidated financial statements included in "Item 8.

Financial Statements and Supplementary Data."

Drilling contractors have retired approximately 120 jackups since the beginning of 2014.

Approximately 90 jackups older than 30 years of age are currently idle and 40 jackups that are 30 years of age or older have contracts expiring by the end of 2021 without follow-on work.

Expenditures required to re-certify these aging rigs may prove cost prohibitive and drilling contractors may instead elect to scrap or cold-stack these rigs.

Improvements in demand and/or reductions in supply will be necessary before meaningful increases in utilization and day rates are realized.

Year Ended December 31, 2020

Revenues declined by $626.0 million, or 30%, as compared to the prior year.

This decline is primarily attributable to a $287.4 million decline in revenue resulting from the sale of VALARIS 5004, VALARIS 5006, VALARIS 6002, VALARIS JU-68, VALARIS JU-84, VALARIS JU-87, VALARIS JU-88, and VALARIS JU-96, which operated in the prior year comparative period, a $286.7 million decline in revenue as a result of fewer days under contract across our fleet, a $150.0 million decline in revenue due to the termination of the VALARIS DS-8 contract and a $28.3 million and $16.0 million, decline in revenues earned under the Secondment Agreement and Transition Services Agreement with ARO, respectively.

Further, the additional revenues earned under Lease Agreements with ARO due to the inclusion of a full year of results in 2020 as compared to the period from April 11, 2019 to December 31, 2019 from the comparable period was offset by a reduction of our rental revenues to reflect an amendment to the Shareholder Agreement that impacted the bareboat charter rate in the lease agreements.

See " Note 5 - Equity Method Investment in ARO" to our consolidated financial statements included in "Item 8.

Financial Statements and Supplementary Data" for additional information.

The decline in revenue was partially offset by $113.6 million of revenue earned by rigs added from the Rowan Transaction, and $46.3 million of contract termination fees received for certain rigs.

Contract drilling expense declined by $347.4 million, or 19%, as compared to the prior year primarily due to a $184.4 million decline as a result of lower costs on idle rigs, $134.5 million lower costs on VALARIS 5004, VALARIS 5006, VALARIS 6002, VALARIS 8500, VALARIS 8501, VALARIS 8502, VALARIS 8504, VALARIS DS-3, VALARIS DS-5, VALARIS DS-6, VALARIS JU-68, VALARIS JU-84, VALARIS JU-87, VALARIS JU-88 and VALARIS JU-96, as these rigs were sold, and reduced costs resulting primarily from spend control efforts.

Additionally, there was a decline in expenses due to a decrease in services provided to ARO under the Secondment Agreement as almost all remaining employees seconded to ARO became employees of ARO

during the second quarter of 2020.

This decrease was partially offset by $140.1 million of contract drilling expenses incurred on rigs added from the Rowan Transaction.

During the first and second quarters of 2020, we recorded non-cash losses on impairment totaling $3.6 billion, with respect to assets in our fleet, primarily due to the adverse change in the current and anticipated market for these assets.

See " Note 7 - Property and Equipment" to our consolidated financial statements included in "Item 8.

Financial Statements and Supplementary Data" for additional information.

Depreciation expense declined by $68.9 million, or 11%, as compared to the prior year period primarily due to lower depreciation expense on certain assets which were impaired during the first and second quarters of 2020, some of which were subsequently sold in the third and fourth quarters of 2020.

This decrease was partially offset by depreciation expense recorded for rigs added in the Rowan Transaction as well as for the VALARIS JU-123 which commenced operations in August 2019.

General and administrative expenses increased by $25.7 million, or 14%, as compared to the prior year period primarily due to the backstop commitment fee and legal and other professional advisor fees incurred in relation to the Chapter 11 Cases, but prior to the Petition Date.

This increase was partially offset by merger related costs incurred in the prior year comparative period.

Other operating income of $118.1 million recognized during 2020 was due to loss of hire insurance recoveries collected for the VALARIS DS-8 non-drilling incident.

Other expense, net, increased by $1.4 billion as compared to the prior year period, primarily due to the prior period $637.0 million gain on bargain purchase recognized in connection with the Rowan Transaction, pre-tax gain related to the settlement award from the SHI matter of $200.0 million and $194.1 million of pre-tax gain on debt extinguishment related to the repurchase of senior notes in connection with July 2019 tender offers.

Additionally, the current year period includes $527.6 million of reorganization items directly related to the Chapter 11 Cases.

Partially offsetting these increases, our Interest Expense, net decreased $137.7 million primarily due to $140.7 million as we discontinued accruing interest on our outstanding debt subsequent to the chapter 11 filing.

Year Ended December 31, 2019

Revenues increased by $347.8 million, or 20%, as compared to the prior year primarily due to $322.2 million of revenue earned by the Rowan rigs, $125.5 million due to revenues earned from our rigs leased to ARO and revenues earned from the Secondment Agreement and Transition Services Agreement, and $84.1 million due to the commencement of VALARIS DS-9, VALARIS JU-123, VALARIS JU-140 and VALARIS JU-141 drilling operations.

This increase was partially offset by the sale of ENSCO 6001, VALARIS 5006 and ENSCO 97, which operated in the prior-year period, and lower average day rates across the remaining fleet.

Contract drilling expense increased by $486.6 million , or 37% , as compared to the prior year primarily due to $351.2 million of contract drilling expense incurred by the Rowan rigs, $57.0 million due to expenses incurred under the Secondment Agreement and by our rigs leased to ARO, $38.2 million due to the commencement of VALARIS DS-9, and $31.3 million due to the commencement of drilling operations for VALARIS JU-123, VALARIS JU-140

and VALARIS JU-141.

Contract drilling expense increased by $486.6 million, or 37%, as compared to the prior year primarily due to $351.2 million of contract drilling expense incurred by the Rowan rigs, $57.0 million due to expenses incurred under the Secondment Agreement and by our rigs leased to ARO, $38.2 million due to the commencement of VALARIS DS-9, and $31.3 million due to the commencement of drilling operations for VALARIS JU-123, VALARIS JU-140 and VALARIS JU-141.

This increase was partially offset by the sale of ENSCO 6001, VALARIS 5006 and ENSCO 97, which operated in the prior-year period.

General and administrative expenses increased by $86.2 million , or 84% , as compared to the prior year period, primarily due to transaction and integration costs associated with the Rowan Transaction.

Year Ended December 31, 2018

Revenues declined by $137.6 million , or 7% , as compared to the prior year.

The decline was primarily due to a decline in average day rates in both our floater and jackup fleets and the sale of several rigs during the year that operated in the year-ago period, partially offset by increased utilization and the addition of Atwood rigs to the fleet in late 2017.

Contract drilling expense increased by $129.9 million , or 11% , as compared to the prior year.

The increase was primarily due to addition of rigs to the fleet from the acquisition of Atwood Oceanics, Inc.

(Atwood) and the commencement of drilling operations for several of our newbuild rigs.

This increase was partially offset by the sale of several rigs during the year that operated in the year-ago period and cost incurred during the prior year to settle a previously disclosed legal contingency.

Excluding the impact of $7.5 million of transaction costs during 2018 and $51.6 million of transaction costs during 2017 from the Atwood acquisition, general and administrative expenses declined by $11.0 million , or 10% , as compared to the prior year.

The decline was primarily due to lower compensation costs and the recovery of certain legal costs awarded to us in connection with the SHI litigation.

General and administrative expenses increased by $86.2 million, or 84%, as compared to the prior year, primarily due to transaction and integration costs associated with the Rowan Transaction.

Operating Income by Segment

Prior to the Rowan Transaction, our business consisted of three operating segments:

(1) Floaters, which included our drillships and semisubmersible rigs, (2) Jackups and (3) Other, which consisted only of our management services provided on rigs owned by third parties.

Our Floaters and Jackups were also reportable segments.

As a result of the Rowan Transaction, we concluded that we would maintain the aforementioned segment structure while adding ARO as a reportable segment for the new combined company.

We also concluded that the

activities associated with our arrangements with ARO, consisting of our Transition Services Agreement, Rig Lease Agreements and Secondment Agreement, do not constitute reportable segments and are therefore included within Other in the following segment disclosures.

Our business consists of four operating segments:

(1) Floaters, which includes our drillships and semisubmersible rigs, (2) Jackups, (3) ARO and (4) Other, which consists of management services on rigs owned by third-parties and the activities associated with our arrangements with ARO under the Rig Lease Agreements, the Secondment Agreement and the Transition Services Agreement.

Floaters, Jackups and ARO are also reportable segments.

Substantially all of the expenses incurred associated with our Transition Services Agreement are included in general and administrative under "Reconciling Items" in the table set forth below.

General and administrative expense and depreciation expense incurred by our corporate office are not allocated to our operating segments for purposes of measuring segment operating income (loss) and are included in "Reconciling Items." The full operating results included below for ARO (representing only results of ARO from the Transaction Date) are not included within our consolidated results and thus deducted under "Reconciling Items" and replaced with our equity in earnings of ARO.

See Note 4 to our consolidated financial statements included in "Item 8.

The full operating results included below for ARO (representing only results of ARO from the closing date of the Rowan Transaction) are not included within our consolidated results and thus deducted under "Reconciling Items" and replaced with our equity in earnings of ARO.

See " Note 5 - Equity Method Investment in ARO" to our consolidated financial statements included in "Item 8.

Financial Statements and Supplementary Data" for additional information on ARO and related arrangements.

Upon establishment of ARO, Rowan entered into (1) an agreement to provide certain back-office services for a period of time until ARO develops its own infrastructure (the "Transition Services Agreement"), and (2) an agreement to provide certain Rowan employees through secondment arrangements to assist with various onshore and offshore services for the benefit of ARO (the "Secondment Agreement").

These agreements remained in place subsequent to the Rowan Transaction.

Pursuant to these agreements, we or our seconded employees provide various services to ARO, and in return, ARO provides remuneration for those services.

During the quarter ended June 30, 2020, almost all remaining employees seconded to ARO became employees of ARO.

Additionally, our services to ARO under the Transition Services Agreement were completed as of December 31, 2020.

See " Note 5 - Equity Method Investment in ARO" to our consolidated financial statements included in "Item 8.

2020 compared to 2019

During 2020, revenues declined by $508.6 million, or 50%, as compared to the prior year due to $241.0 million from the sale of VALARIS 5004, VALARIS 5006, and VALARIS 6002, which operated in the prior year comparative period, $189.4 million as a result of fewer days under contract across the floater fleet and $150.0 million due to the termination of the VALARIS DS-8 contract.

This decline was partially offset by $46.3 million of contract termination fees received for certain rigs and $40.1 million earned by rigs added in the Rowan Transaction.

Contract drilling expense declined by $264.7 million, or 29%, as compared to the prior year primarily due to $131.1 million lower cost on idle rigs, $92.3 million lower costs on VALARIS 5004, VALARIS 5006, VALARIS 6002, VALARIS 8500, VALARIS 8501, VALARIS 8502, VALARIS 8504, VALARIS DS-3, VALARIS DS-5 and VALARIS DS-6, as such rigs were sold, and reduced costs resulting primarily from spend control efforts.

This decrease was partially offset by $53.8 million of contract drilling expense incurred by rigs added in the Rowan Transaction.

During 2020, we recorded a non-cash loss on impairment of $3.4 billion, with respect to assets in our Floater segment due to the adverse change in the current and anticipated market for these assets.

See " Note 7 -Property and Equipment" to our consolidated financial statements included in "Item 8.

Financial Statements and Supplementary Data" for additional information.

Depreciation expense declined by $99.5 million, or 27%, compared to the prior year primarily due to lower depreciation on certain non-core assets which were impaired during the first and second quarters of 2020 and subsequently sold in the third and fourth quarters of 2020 with the exception of one floater.

Other operating income of $118.1 million recognized during 2020 was due to loss of hire insurance recoveries collected for the VALARIS DS-8 non-drilling incident.

ARO currently owns a fleet of seven jackup rigs, leases another nine jackup rigs from us and plans to purchase up to 20 newbuild jackup rigs over an approximate 10 year period.

Depreciation expense increased by $50.0 million, or 33%, as compared to the prior year primarily due to the addition of rigs in the Rowan Transaction and the commencement of VALARIS JU-123 in August 2019.

ARO currently owns a fleet of seven jackup rigs, leases another nine jackup rigs from us and has plans to purchase 20 newbuild jackup rigs over an approximate 10 year period.

In January 2020, ARO ordered the first two newbuild jackups with delivery scheduled in 2022.

The rigs we lease to ARO are done so through bareboat charter agreements whereby substantially all operating costs are incurred by ARO.

The joint venture partners intend for the newbuild jackup rigs to be financed out of available cash from ARO's operations and/or funds available from third-party debt financing.

ARO paid a 25% down payment from cash on hand for each of the newbuilds ordered in January 2020.

In the event ARO has insufficient cash from operations or is unable to obtain third-party financing, each partner may periodically be required to make additional capital contributions to ARO, up to a maximum aggregate contribution of $1.25 billion from each partner to fund the newbuild program.

The Company's capital contributions to ARO pursuant to this requirement may require approval of the Bankruptcy Court during the Chapter 11 Cases.

Each partner's commitment shall be reduced by the actual cost of each newbuild rig, on a proportionate basis.

The joint venture partners agreed that Saudi Aramco, as a customer, will provide drilling contracts to ARO in connection with the acquisition of the newbuild rigs.

The initial contracts for each newbuild rig will be determined using a pricing mechanism that targets a six-year payback period for construction costs on an EBITDA basis.

The initial eight-year contracts will be followed by a minimum of another eight years of term, re-priced in three-year intervals based on a market pricing mechanism.

We lease rigs to ARO through bareboat charter agreements whereby substantially all operating costs are incurred by ARO.

All nine jackup rigs leased to ARO are under three-year contracts with Saudi Aramco.

All seven ARO-owned jackup rigs are under long-term contracts with Saudi Aramco.

The operating revenues of ARO reflect revenues earned under drilling contracts with Saudi Aramco for the seven ARO-own jackup rigs and the nine rigs leased from us that operated during the period from the Transaction Date through December 31, 2019 .

The contract drilling, depreciation and general and administrative expenses are also for the period from the Transaction Date through December 31, 2019 .

Contract drilling expenses are inclusive of the bareboat charter fees for the rigs leased from us and costs incurred under the Secondment Agreement.

The operating revenues of ARO reflect revenues earned under drilling contracts with Saudi Aramco for the seven ARO-own jackup rigs that operated during the period from the date of the Rowan Transaction in April 2019 through December 31, 2020.

The contract drilling, depreciation and general and administrative expenses are also for the period from the date of the Rowan Transaction in April 2019 through December 31, 2020.

Contract drilling expenses are inclusive of the bareboat charter fees for the rigs leased from us.

Costs incurred under the Secondment Agreement are included in contract drilling expense and general and administrative, depending on the function to which the seconded employees' services related.

General and administrative expenses include costs incurred under the Transition Services Agreement and other administrative costs.

Depreciation expense increased by $14.5 million, or 36%, in 2020 as compared to the prior year period from the date of the Rowan Transaction in April 2019 through December 31, 2019 primarily due to a full year of ARO results in 2020 compared to a partial year in 2019.

General and administrative expenses decreased by $2.9 million, or 11%, in 2020 as compared to the prior year period from the date of the Rowan Transaction in April 2019 through December 31, 2019 primarily due to a decrease in services received under the Transition Services Agreement.

See " Note 5 - Equity Method Investment in ARO" to our consolidated financial statements included in "Item 8.

2020 compared to 2019

Other revenues declined $48.1 million, or 24%, for the year ended December 31, 2020, as compared to the prior year period, primarily due to due to lower revenues earned under the Secondment Agreement and Transition Services Agreement with ARO of $28.3 million and $16.0 million, respectively.

Further, the additional revenues earned under Lease Agreements due to the inclusion of a full year of results in 2020 as compared to the period from April 11, 2019 to December 31, 2019 from the comparable period was offset by a reduction of our rental revenues to reflect an amendment to the Shareholder Agreement that impacted the bareboat charter rate in the lease agreements.

See " Note 4 - Rowan Transaction" to our consolidated financial statements included in "Item 8.

Financial Statements and Supplementary Data" for additional information.

Depreciation expense increased $19.3 million, or 76%, as compared to the prior year primarily due to the impact of full year results for 2020 as compared to the prior year period from the date of the Rowan Transaction in April 2019 through December 31, 2019 as well as additional depreciation due to capital expenditures and the commencement of the Bess Brants and Ernest Dees which were in the shipyard most of the comparative period.

2019 compared to 2018

Other revenues increased $143.2 million, or 235%, for the year ended December 31, 2019, as compared to the prior year period, primarily due to revenues earned from our rigs leased to ARO, revenues earned under the Secondment Agreement and Transition Services Agreement of $58.2 million, $49.9 million and $17.3 million, respectively.

LIQUIDITY AND CAPITAL RESOURCES

We proactively manage our capital structure in an effort to most effectively execute our strategic priorities and maximize value for shareholders.

In support of these objectives, we are focused on our liquidity, debt levels and maturity profile and cost of capital.

Over the past several years, we have executed a number of financing transactions to improve our financial position and manage our debt maturities, including the July 2019 tender offers discussed below.

Based on our balance sheet, our contractual backlog and $1.6 billion of undrawn capacity under our credit facility, we expect to fund our liquidity needs, including expected negative operating cash flows, contractual obligations, anticipated capital expenditures, as well as working capital requirements, from cash and funds borrowed under our credit facility or other future financing arrangements, including available shipyard financing options for our two drillships under construction.

Our credit facility is an integral part of our financial flexibility and liquidity.

We also may rely on the issuance of debt and/or equity securities in the future to supplement our liquidity needs.

In addition, we may seek to extend our maturities and reduce the overall principal amount of our debt through exchange offers or other liability management transactions.

Our liability management efforts, if undertaken, may be unsuccessful or may not improve our financial position to the extent anticipated.

Additionally, as a result of the Rowan Transaction, we acquired the following debt:

Upon closing of the Rowan Transaction, we terminated Rowan's outstanding credit facilities.

During the three-year period ended December 31, 2019 , our primary sources of cash were $1.4 billion from net maturities of short-term investments, $1.0 billion in proceeds from the issuance of senior notes, and Rowan cash acquired of $931.9 million .

Our primary uses of cash during the same period included $2.2 billion for the repurchase and redemption of outstanding debt, $1.2 billion for the construction, enhancement and other improvement of our drilling rigs, including $813.7 million invested in newbuild construction, $871.6 million for the repayment of Atwood debt and $36.2 million for dividend payments.

Explanations of our liquidity and capital resources for each of the years in the three-year period ended December 31, 2019 are set forth below.

Chapter 11 Cases and Effect of Automatic Stay

On August 19, 2020, the Debtors filed voluntary petitions for reorganization under chapter 11 of the Bankruptcy Code in the Bankruptcy Court and subsequently obtained joint administration of the Chapter 11 Cases under the caption In re Valaris plc, et al.

20-34114 (MI).

Any efforts to enforce payment obligations

related to the acceleration of our debt have been automatically stayed as a result of the filing of the Chapter 11 Cases, and the creditors’ rights of enforcement are subject to the applicable provisions of the Bankruptcy Code.

On August 18, 2020, the Debtors entered into the Original RSA with the Consenting Noteholders.

On February 5, 2021, the Debtors entered into the Amended RSA with the Consenting Noteholders and the Consenting Lenders.

The Amended RSA contemplates that the Company will implement the restructuring through the Chapter 11 Cases pursuant to a plan of reorganization and the various related transactions set forth in or contemplated by the Amended RSA.

Notwithstanding the general applicability of the automatic stay described above, governmental authorities may determine to continue actions brought under their regulatory powers.

The Debtors continue to operate their businesses and manage their properties as “debtors-in-possession” under the jurisdiction of the Bankruptcy Court and in accordance with applicable provisions of the Bankruptcy Code and orders of the Bankruptcy Court.

As part of the Chapter 11 Cases, the Debtors were granted “first-day” relief which enabled the Company to continue operating without interruption or disruption to its relationships with its customers and vendors or its high-quality service delivery.

In particular, employee pay and benefits are expected to continue without interruption.

In addition, we have obtained a DIP Facility to fund operations during the bankruptcy proceedings.

However, for the duration of the Chapter 11 Cases, our operations and our ability to develop and execute our business plan are subject to a high degree of risk and uncertainty associated with the Chapter 11 Cases.

The outcome of the Chapter 11 Cases is dependent upon factors that are outside of our control, including actions of the Bankruptcy Court and our creditors.

Our liquidity position as of December 31, 2020, 2019 and 2018 is summarized below (in millions, except ratios):

2020 2019 2018

Cash and cash equivalents $ 325.8 $ 97.2 $ 275.1

Short-term investments — — 329.0

Available DIP Facility capacity 500.0 — —

Available credit facility borrowing capacity — 1,622.2 2,000.0

Total liquidity $ 825.8 $ 1,719.4 $ 2,604.1

Working capital $ 746.1 $ 233.7 $ 781.2

Current ratio (1)

(1) As a result of our chapter 11 filing, we reclassified $7.3 billion representing the principal balance on our unsecured Senior Notes (as defined below), the amount of outstanding borrowings on our revolving credit facility, the accrued interest on our senior notes and revolving credit facility, and rig holding costs for DS-13 and DS-14 to “Liabilities Subject to Compromise” as of December 31, 2020.

The current ratio calculated above does not reflect our debt and related interest that would otherwise be current but is stayed under our Chapter 11 Cases, nor does it include rig holding costs for VALARIS DS-13 and VALARIS DS-14.

Cash and Debt

As discussed in " Note 2 - Chapter 11 Proceedings and Ability to Continue as a Going Concern" to our consolidated financial statements included in "Item 8.

Financial Statements and Supplementary Data" for information on Chapter 11 Cases and above, we have filed the Chapter 11 Cases to effect a comprehensive restructuring of our indebtedness.

The commencement of the Chapter 11 Cases on August 19, 2020, constituted an event of default under our Senior Notes and revolving credit facility.

On September 2 5, 2020, we entered into the $500.0 million DIP Facility to provide liquidity during the pendency of the Chapter 11 Cases and expect exit financing in the form of a fully backstopped rights offering to noteholders for $550 million of New Secured Notes.

We expect the DIP Facility will provide sufficient liquidity for us during the pendency of the Chapter 11 Cases.

Additionally, we expect the exit financing to include the backstopped New Secured Notes and that these notes will provide the necessary liquidity to support ongoing operations and working capital needs.

The maturity date of the DIP Credit Agreement is the earliest of (1) August 17, 2021, (2) acceleration of the loans under the DIP Facility and termination of the lenders' commitments under the DIP Facility, (3) the substantial consummation of any plan filed in the Chapter 11 Cases that is confirmed pursuant to an order entered by the Bankruptcy Court and (4) the consummation of a sale of all or substantially all of the assets of the Company and the other Debtors under section 363 of the Bankruptcy Code.

Loans under the DIP Credit Agreement accrue interest at a rate of 8.00% per annum, if paid in kind, and at a rate of 7.00% per annum, if paid in cash.

The DIP Credit Agreement contains a requirement that the Company and any other borrowers provide every four weeks, a rolling 13 week budget to be approved by the required lenders (the “Approved Budget”).

The Company and any other borrower that becomes party to the DIP Credit Agreement may not vary from the Approved Budget by more than 15% of the forecasted amounts in any forecast period.

The Approved Budget is, subject to certain exceptions and is tested at certain times in accordance with the DIP Credit Agreement in order to measure variances between the actual total cash disbursements (excluding professional fees and certain other items consistent with the initial Approved Budget) and the disbursements budgeted for the applicable period.

As of December 31, 2020, there were no borrowings outstanding under the DIP Credit Agreement.

The DIP Credit Agreement does not provide for the issuance of letters of credit but permits occurrence of letters of credit in certain circumstances.

Any proceeds of the loans under the DIP Credit Agreement may be used (1) to provide working capital to the borrowers and their subsidiaries and for other general corporate purposes in accordance with the rolling 13 week budget to be approved by the required lenders every four weeks (subject to the Permitted Variance), (2) to pay interest, fees, costs and expenses related to the DIP Facility, (3) to pay fees, costs and expenses of the estate professionals retained for the Chapter 11 Cases as approved by the Bankruptcy Court and as provided for in the Approved Budget (subject to the Permitted Variance), (4) make all permitted payments of costs of administration of the Chapter 11 Cases, (5) pay pre-petition expenses as are consistent with the Approved Budget (subject to the Permitted Variance) and approved by the Bankruptcy Court, (6) to fund the reasonable activities, costs and fees in respect of any insolvency proceedings in the United Kingdom and (7) make other payments permitted by the applicable Approved Budget.

The DIP Credit Agreement contains events of default customary to debtor-in-possession financings, including events related to the Chapter 11 Cases, the occurrence of which could result in the acceleration of the Debtors’ obligation to repay the outstanding indebtedness under the DIP Credit Agreement.

The Debtors’ obligations under the DIP Credit Agreement are secured by a security interest in, and lien on, substantially all present and after acquired property (subject to certain exceptions) of the Debtors and are guaranteed by certain of the Company’s subsidiaries, including other Debtors.

The DIP Credit Agreement also contains customary covenants that limit the ability of the Company and its subsidiaries to, among other things, (1) incur additional indebtedness and permit liens to exist on their assets, (2) pay dividends or make certain other restricted payments, (3) sell assets and (4) make certain investments.

These covenants are subject to exceptions and qualifications as set forth in the DIP Credit Agreement.

During the three-year period ended December 31, 2020, our primary sources of cash were $1.0 billion in proceeds from issuance of senior notes, Rowan cash acquired of $931.9 million, $581.0 million in net borrowings under our revolving credit facility and $440.0 million from short-term investments, net.

While the revolving credit facility has not been terminated, no further borrowings are permitted.

Our primary uses of cash for the same period were $1.7 billion for the repurchase and redemption of outstanding debt, $747.5 million for the construction, enhancement and other improvements of our drilling rigs and $584.3 million used in operating activities.

Cash Flows and Capital Expenditures

Our cash flows from operating activities of continuing operations and capital expenditures on continuing operations for each of the years in the three-year period ended December 31, 2020 were as follows (in millions):

Net cash provided by (used in) operating activities of continuing operations

2020 2019 2018

Net cash used in operating activities of continuing operations $ (251.7) $ (276.9) $ (55.7)

Capital expenditures $ 93.8 $ 227.0 $ 426.7

New rig construction

Rig enhancements

Minor upgrades and improvements

During 2020, cash flows used in operating activities decreased by $25.2 million as compared to the prior year due to lower interest costs, partially offset by declining margins.

During 2019, cash flows from continuing operations declined by $221.2 million as compared to the prior year due primarily to costs incurred related to the Rowan Transaction, interest on the debt assumed in the Rowan Transaction and declining margins.

As our remaining above-market contracts expire and utilization increases with the execution of new market-rate contracts, coupled with the potential impact of rig reactivation costs, our operating cash flows will remain negative through at least 2020.

During 2018 , cash flows from continuing operations declined by $315.1 million , or 121% , as compared to the prior year due primarily to declining margins and higher cash interest expense due to the debt financing transactions we undertook during the first quarter of 2018.

Based on our current projections, excluding integration-related capital expenditures, we expect capital expenditures during 2020 to approximate $160.0 million for newbuild construction, rig enhancement projects and minor upgrades and improvements.

Approximately $30 million of our projected capital expenditures is reimbursable by our customers.

Depending on market conditions and opportunities, we may reduce our planned expenditures or make additional capital expenditures to upgrade rigs for customer requirements or acquire additional rigs.

Our Board of Directors declared a $0.01 quarterly cash dividend, on a pre-reverse stock split basis, for the first quarter of 2019 .

Beginning in the second quarter of 2019, our Board of Directors determined that we will not pay a regular quarterly cash dividend.

The declaration and amount of future dividends is at the discretion of our Board of Directors and could change in future periods.

Our revolving credit facility prohibits us from paying dividends in excess of $0.01 per share per fiscal quarter.

Dividends in excess of this amount would require the amendment or waiver of such provision.

Based on our current projections, we expect capital expenditures during 2021 to approximate $42.5 million for rig enhancement projects and minor upgrades and improvements.

Depending on market conditions and opportunities, we may reduce our planned expenditures or make additional capital expenditures to upgrade rigs for customer requirements.

As of December 31, 2020, we were in compliance with our covenants under the DIP Credit Agreement.

The commencement of the Chapter 11 Cases resulted in an event of default under each series of our Senior Notes and all obligations thereunder were accelerated.

However, any efforts to enforce payment obligations related to the acceleration of our debt have been automatically stayed as a result of the filing of the Chapter 11 Cases.

Revolving Credit Facility and DIP Facility

Effective upon closing of the Rowan Transaction, our revolving credit facility was $1.6 billion.

As previously disclosed, prior to the commencement of the Chapter 11 Cases, we entered into a series of waiver agreements (the “Waivers”) between the dates of June 1, 2020 and August 3, 2020 in respect of the revolving credit facility.

The Waivers did not address any event of default resulting under the revolving credit facility attributed to the filing of Chapter 11 Cases.

Consequently, the principal and interest under our revolving credit facility became immediately due and payable upon filing of such Chapter 11 Cases, which constituted an event of default under the revolving credit facility.

However, the ability of the lenders under the revolving credit facility to exercise remedies in respect of the revolving credit facility was stayed upon commencement of the Chapter 11 Cases.

While the revolving credit facility has not been terminated, notwithstanding the $1.6 billion borrowing capacity under the revolving credit facility, no further borrowings under the revolving credit facility are permitted.

As of December 31, 2020 , we had $581.0 million of borrowings outstanding under our revolving credit facility and $27.0 million of undrawn letters of cred it.

The outstanding borrowings as well as accrued interest as of the Petition Date are classified as Liabilities Subject to Compromise in our Consolidated Balance Sheet as of December 31, 2020.

See " Note 2 - Chapter 11 Proceedings and Ability to Continue as a Going Concern" to our consolidated financial statements included in "Item 8.

Financial Statements and Supplementary Data" for more information related to our Chapter 11 Cases to effect a comprehensive restructuring of our indebtedness.

We expect cash on hand and the DIP Facility will provide sufficient liquidity for us during the pendency of the Chapter 11 Cases based on current projections of cash flows.

Should we experience material variations from our projected cash flows, this could result in us having insufficient liquidity from the DIP Facility and in turn could have a material adverse impact on our financial position, operating results or cash flows.

The original principal amounts issued under our senior notes have subsequently changed as a result of our tenders, repurchases, exchanges, redemptions and new debt issuances such that the balance outstanding at December 31, 2020 were as follows (in millions):

4.875% Senior notes due 2022 (1)

During the year ended December 31, 2017, we recognized a pre-tax loss on the exchange offers of approximately $6.2 million .

Revolving Credit

Effective upon closing of the Rowan Transaction, we amended our credit facility to, among other changes, increase the borrowing capacity.

Previously, our credit facility had a borrowing capacity of $2.0 billion through September 2019 that declined to $1.3 billion through September 2020 and $1.2 billion through September 2022.

Subsequent to the amendment, our borrowing capacity was $1.7 billion through September 2022.

Following the amendment, our borrowing capacity was reduced by $75 million to $1.6 billion .

The reduction occurred after we became aware that a signatory for a purported lender was not an authorized representative of that lender and therefore concluded the $75 million was not binding.

The credit agreement governing the credit facility includes an accordion feature allowing us to increase the future commitments by up to an aggregate amount not to exceed $250.0 million .

Advances under the credit facility bear interest at Base Rate or LIBOR plus an applicable margin rate, depending on our credit ratings.

We are required to pay a quarterly commitment fee on the undrawn portion of the $1.6 billion commitment, which is also based on our credit ratings.

On December 6, 2019, Moody's downgraded our corporate family rating from B3 to Caa1 and our senior unsecured notes from Caa1 to Caa2.

Previously, in September 2019, Standard & Poor's downgraded our senior unsecured bonds from B to B- and our issuer rating from B- to CCC+.

The rating actions did not impact the interest rates applicable to our borrowings and the quarterly commitment fee on the undrawn portion of the $1.6 billion commitment.

The applicable margin rates are 3.25% per annum for Base Rate advances and 4.25% per annum for LIBOR advances.

The quarterly commitment fee is 0.75% per annum on the undrawn portion of the $1.6 billion commitment.

The credit facility requires us to maintain a total debt to total capitalization ratio that is less than or equal to 60% and to provide guarantees from certain of our rig-owning subsidiaries sufficient to meet certain guarantee coverage ratios.

The credit facility also contains customary restrictive covenants, including, among others, prohibitions on creating, incurring or assuming certain debt and liens (subject to customary exceptions, including a permitted lien basket that permits us to raise secured debt up to the lesser of $1 billion or 10% of consolidated tangible net worth (as defined in the credit facility));

entering into certain merger arrangements;

selling, leasing, transferring or otherwise disposing of all or substantially all of our assets;

making a material change in the nature of the business;

paying or distributing dividends on our ordinary shares (subject to certain exceptions, including the ability to pay a quarterly dividend of $0.01 per share);

borrowings, if after giving effect to any such borrowings and the application of the proceeds thereof, the aggregate amount of available cash (as defined in the credit facility) would exceed $200 million ;

and entering into certain transactions with affiliates.

The credit facility also includes a covenant restricting our ability to repay indebtedness maturing after September 2022, which is the final maturity date of our credit facility.

This covenant is subject to certain exceptions that permit us to manage our balance sheet, including the ability to make repayments of indebtedness (i) of acquired companies within 90 days of the completion of the acquisition or (ii) if, after giving effect to such repayments, available cash is greater than $250 million and there are no amounts outstanding under the credit facility.

As of December 31, 2019 , we were in compliance in all material respects with our covenants under the credit facility.

We expect to remain in compliance with our credit facility covenants during 2020 .

We had no amounts outstanding under the credit facility as of December 31, 2019 and 2018 .

As of January 31, 2020, we had $90 million of total outstanding borrowings under our credit facility.

Our access to credit and capital markets is limited because of our credit rating.

Our current credit ratings, and any additional actual or anticipated downgrades in our corporate credit ratings or the credit rating of our notes will limit our ability to access credit and capital markets, or to restructure or refinance our indebtedness.

In addition, future financings or refinancings will result in higher borrowing costs and may require collateral and/or more restrictive terms and covenants, which may further restrict our operations.

Limitations on our ability to access credit and capital markets could have a material adverse impact on our financial position, operating results or cash flows.

Other Financing Arrangements

We filed an automatically effective shelf registration statement on Form S-3 with the U.S.

Securities and Exchange Commission on November 21, 2017, which provides us the ability to issue debt securities, equity securities, guarantees and/or units of securities in one or more offerings.

The registration statement expires in November 2020.

During 2018, our shareholders approved our current share repurchase program.

Subject to certain provisions under English law, including the requirement of the Company to have sufficient distributable reserves, we may repurchase shares up to a maximum of $500 million in the aggregate from one or more financial intermediaries under the program, but in no case more than 16.3 million shares.

Subject to certain provisions under English law, including the requirement of the Company to have sufficient distributable reserves and the Board to conclude that a repurchase is in the best interests of Valaris plc taking into account the interests of relevant stakeholders, we may repurchase shares up to a maximum of $500 million in the aggregate from one or more financial intermediaries under the program, but in no case more than 16.3 million shares.

The program terminates in May 2023.

As of December 31, 2020, there had been no share repurchases under this program.

Our credit facility prohibits us from repurchasing our shares, except in certain limited circumstances.

Any share repurchases, outside of such limited circumstances, would require the amendment or waiver of such provision.

From time to time, we and our affiliates may repurchase our outstanding senior notes in the open market, in privately negotiated transactions, through tender offers, exchange offers or otherwise, or we may redeem senior notes, pursuant to their terms.

In connection with any exchange, we may issue equity, issue new debt (including debt that is structurally senior to our existing senior notes) and/or pay cash consideration.

Any future repurchases, exchanges or redemptions will depend on various factors existing at that time.

There can be no assurance as to which, if any, of these alternatives (or combinations thereof) we may choose to pursue in the future or, if any such alternatives are pursued, that they will be successful.

There can be no assurance that an active trading market will exist for our outstanding senior notes following any such transaction.

Our DIP Credit Agreement only permits the repurchase of our shares in certain limited circumstances and the repurchase of shares would likely require approval of the bankruptcy court.

We do not currently expect to make repurchases under the program whilst Valaris plc remains subject to Chapter 11 bankruptcy proceedings.

We expect to fund these commitments from existing cash and short-term investments and funds borrowed under our credit facility or other future financing arrangements, including available shipyard financing options for our two drillships under construction.

The actual timing of our new rig construction and rig enhancement payments may vary based on the completion of various milestones, which are beyond our control.

(1) During 2019, we entered into amendments to our construction agreements with the shipyard for VALARIS DS-13 and VALARIS DS-14 to provide for, among other things, two-year extensions of the delivery date of each rig in exchange for payment of all accrued holding costs through March 31, 2019, totaling approximately $23 million .

The new delivery dates for the VALARIS DS-13 and VALARIS DS-14 are September 30, 2021 and June 30, 2022, respectively.

We can elect to request earlier delivery in certain circumstances.

The interest rate on the final milestone payments increased from 5% to 7% per annum from October 1, 2019, for the VALARIS DS-13, and from July 1, 2020, for the VALARIS DS-14, until the actual delivery dates.

The final milestone payments and applicable interest are due at the new delivery dates (or, if accelerated, the actual delivery dates) and are estimated to be approximately $313.3 million in aggregate for both rigs, inclusive of interest, assuming we take delivery on the new delivery date.

of making the final milestone payments, we have the option to take delivery of the rigs and issue a promissory note for each rig to the shipyard owner for the amount due.

If we issue the promissory note to the shipyard owner, we would also be required to provide a guarantee from Valaris plc.

(1) As a result of our chapter 11 filing, we reclassified $7.1 billion representing the principal balance on our unsecured senior notes and the amount of outstanding borrowings on our revolving credit facility to Liabilities Subject to Compromise on our Consolidated Balance Sheet as of December 31, 2020 .

(2) As of December 31, 2020, the contractual delivery dates for the VALARIS DS-13 and VALARIS DS-14 were September 30, 2021 and June 30, 2022, respectively.

The remaining milestone payments for VALARIS DS-13 and VALARIS DS-14 are included in the table above in the period in which they were contractually owed .

The Amended RSA provides that on or before the effective date of the reorganization, the construction contracts for these rigs shall be rejected under Section 365 of the Bankruptcy Code, unless otherwise agreed between the shipyard and the Company with the consent of required consenting noteholders.

If rejected, it is contemplated that we would have to pay an amount equal to the liquidation recovery, which is the amount the contract counterparty would be entitled to receive or retain if the applicable Company entity was liquidated under chapter 7 of the Bankruptcy Code.

Prior to December 31, 2020, a Stipulation was filed with the Bankruptcy Court which included an Assumption Term Sheet stating amended terms of these construction agreements.

Following further negotiations, we entered into amended agreements with the shipyard on February 26, 2021 that become effective upon our emergence from bankruptcy.

The amendments provide for, among other things, an option construct whereby the Company has the right, but not the obligation, to take delivery of either or both rigs on or before December 31, 2023.

Under the amended agreements, the purchase price for the rigs are estimated to be approximately $119.1 million for the VALARIS DS-13 and $218.3 million for the VALARIS DS-14, assuming a December 31, 2023 delivery date.

Delivery can be requested any time prior to December 31, 2023 with a downward purchase price adjustment based on predetermined terms.

If the Company elects not to purchase the rigs, the Company has no further obligations to the shipyard.

We expect to fund our liquidity needs, including contractual obligations and anticipated capital expenditures, as well as working capital requirements, from our cash, and funds borrowed under our credit facility or future financing arrangements, including available shipyard financing options for our two drillships under construction.

We may rely on the issuance of debt and/or equity securities in the future to supplement our liquidity needs.

As of December 31, 2019 , we had no amounts drawn under our credit facility and $1.6 billion in remaining borrowing capacity.

Our credit facility is an integral part of our financial flexibility and liquidity.

We also may rely on the issuance of debt and/or equity securities in the future to supplement our liquidity needs.

In addition, we may seek to extend our maturities and reduce the overall principal amount of our debt through exchange offers or other liability management transactions.

Our liability management efforts, if undertaken, may be unsuccessful or may not improve our financial position to the extent anticipated.

Our access to credit and capital markets is limited because of our credit rating.

In addition, future financings or refinancings will result in higher borrowing costs and may require collateral and/or more restrictive terms and covenants, which may further restrict our operations.

Limitations on our ability to access credit and capital markets could have a material adverse impact on our financial position, operating results or cash flows.

Recent Tax Assessments

During 2019, we received income tax assessments totaling approximately €142.0 million (approximately $159.0 million converted using the current period-end exchange rates) and A$101 million (approximately $70.9 million converted at current period-end exchange rates) from taxing authorities in Luxembourg and Australia, respectively.

We are contesting these assessments and have filed applications for appeal.

During 2019, the Australian tax authorities issued aggregate tax assessments totaling approximately A$101 million (approximately $77.7 million converted at current period-end exchange rates) plus interest related to the examination of certain of our tax returns for the years 2011 through 2016.

During the third quarter of 2019, we made a A$42 million payment (approximately $29 million at then-current exchange rates) to the Australian tax authorities to litigate the assessment.

We may make a payment to the Luxembourg tax authorities in advance of the final resolution of these assessments.

Although the outcome of such assessments cannot be predicted with certainty, unfavorable outcomes could have a material adverse effect on our liquidity.

We have recorded a $119.0 million liability for these assessments as of December 31, 2019.

See Note 12 included in "Item 8.

We have a $17.9 million liability for unrecognized tax benefits relating to these assessments as of December 31, 2020.

We believe our tax returns are materially correct as filed, and we are vigorously contesting these assessments.

Although the outcome of such assessments and related administrative proceedings cannot be predicted with certainty, we do not expect these matters to have a material adverse effect on our financial position, operating results and cash flows.

This agreement, known as the Paris Agreement, entered into force on November 4, 2016 and, as of February 2019, had been ratified by 187 of the 197 parties to the United Nations Framework Convention on Climate Change, including the United Kingdom, the United States and the majority of the other countries in which we operate.

However, in 2019, the United States formally initiated the process of withdrawing from participation in the Paris Agreement, with such withdrawal taking place no earlier than November 4, 2020.

In response to the announced withdrawal plan, a number of state and local governments in the United States have expressed intentions to take GHG-related actions by implementing their own programs to reduce GHG emissions.

The United Nations Climate Change Conference held in Katowice, Poland in December 2018 adopted further rules regarding the implementation of the Paris Agreement and, in connection with this conference, numerous countries issued commitments to increase their GHG emission reduction targets.

Although the United States had withdrawn from the Paris Agreement in November 2020, the current Presidential Administration officially reentered the United States into the agreement in February 2021.

It is expected that new executive orders, regulatory action, and/or legislation targeting greenhouse gas emissions, or prohibiting, restricting, or delaying oil and gas development activities in certain areas, will be proposed and/or promulgated.

For example, the acting Secretary of the Department of the Interior recently issued

an order preventing staff from producing any new federal fossil fuel leases or permits without sign-off from a top political appointee.

In addition, the current Presidential Administration has issued multiple executive orders pertaining to environmental regulations and climate change, including the (1) Executive Order on Protecting Public Health and the Environment and Restoring Science to Tackle the Climate Crisis and (2) Executive Order on Tackling the Climate Crisis at Home and Abroad.

The latter executive order announced a moratorium on new oil and gas leasing on federal lands and offshore waters pending completion of a comprehensive review and reconsideration of Federal oil and gas permitting and leasing practices, established climate change as a primary foreign policy and national security consideration and affirmed that achieving net-zero greenhouse gas emissions by or before mid-century is a critical priority.

In an effort to reduce GHG emissions, governments have implemented or considered legislative and regulatory mechanisms to institute carbon pricing mechanisms, such as the European Union’s Emission Trading System, and to impose technical requirements to reduce carbon emissions.

If such legislation were to be adopted in the U.S., such legislation could adversely impact many industries.

In the absence of federal legislation, almost half of the states have begun to address GHG emissions, primarily through the development or planned development of emission inventories or regional GHG cap and trade programs.

Future regulation of GHG emissions could occur pursuant to future treaty obligations, statutory or regulatory changes or new climate change legislation in the jurisdictions in which we operate.

We are currently unable to predict the manner or extent of any such effect.

In addition, there have also been efforts in recent years to influence the investment community, including investment advisors and certain sovereign wealth, pension and endowment funds promoting divestment of fossil fuel equities and pressuring lenders to limit funding to companies engaged in the extraction of fossil fuel reserves.

Such environmental activism and initiatives aimed at limiting climate change and reducing air pollution could ultimately interfere with our business activities and operations.

In addition, in recent years the investment community, including investment advisors and certain sovereign wealth, pension and endowment funds, has promoted divestment of fossil fuel equities and pressured lenders to cease or limit funding to companies engaged in the extraction of fossil fuel reserves.

Such environmental initiatives aimed at limiting climate change and reducing air pollution could ultimately interfere with our business activities and operations.

Finally, increasing attention to the risks of climate change has resulted in an increased possibility of lawsuits brought by public and private entities against oil and gas companies in connection with their greenhouse gas emissions.

Should we be targeted by any such litigation, we may incur liability, which, to the extent that societal pressures or political or other factors are involved, could be imposed without regard to the company’s causation of or contribution to the asserted damage, or to other mitigating factors.

We use derivatives to reduce our exposure to foreign currency exchange rate risk.

Our functional currency is the U.S.

As is customary in the oil and gas industry, a majority of our revenues and expenses are denominated in U.S.

however, a portion of the revenues earned and expenses incurred by certain of our subsidiaries are denominated in currencies other than the U.S.

We maintain a foreign currency exchange rate risk management strategy that utilizes derivatives to reduce our exposure to unanticipated fluctuations in earnings and cash flows caused by changes in foreign currency exchange rates.

We utilize cash flow hedges to hedge forecasted foreign currency denominated transactions, primarily to reduce our exposure to foreign currency exchange rate risk on future expected contract drilling expenses and capital expenditures denominated in various foreign currencies.

We predominantly structure our drilling contracts in U.S.

dollars, which significantly reduces the portion of our cash flows and assets denominated in foreign currencies.

As of December 31, 2019 , we had cash flow hedges outstanding to exchange an aggregate $199.1 million for various foreign currencies.

We have net assets and liabilities denominated in numerous foreign currencies and use various strategies to manage our exposure to changes in foreign currency exchange rates.

We occasionally enter into derivatives that hedge the fair value of recognized foreign currency denominated assets or liabilities, thereby reducing exposure to earnings fluctuations caused by changes in foreign currency exchange rates.

We do not designate such derivatives as hedging instruments.

In these situations, a natural hedging relationship generally exists whereby changes in the fair value of the derivatives offset changes in the carrying value of the underlying hedged items.

As of December 31, 2019 , we held derivatives not designated as hedging instruments to exchange an aggregate $47.1 million for various foreign currencies.

If we were to incur a hypothetical 10% adverse change in foreign currency exchange rates, net unrealized losses associated with our foreign currency denominated assets and liabilities as of December 31, 2019 would approximate $27.1 million .

Approximately $1.6 million of these unrealized losses would be offset by corresponding gains on the derivatives utilized to offset changes in the fair value of net assets and liabilities denominated in foreign currencies.

We utilize derivatives and undertake foreign currency exchange rate hedging activities in accordance with our established policies for the management of market risk.

We mitigate our credit risk relating to counterparties of our derivatives through a variety of techniques, including transacting with multiple, high-quality financial institutions, thereby limiting our exposure to individual counterparties and by entering into International Swaps and Derivatives Association, Inc.

(“ISDA”) Master Agreements, which include provisions for a legally enforceable master netting agreement, with our derivative counterparties.

The terms of the ISDA agreements may also include credit support requirements, cross default provisions, termination events or set-off provisions.

Legally enforceable master netting agreements reduce credit risk by providing protection in bankruptcy in certain circumstances and generally permitting the closeout and netting of transactions with the same counterparty upon the occurrence of certain events.

We do not enter into derivatives for trading or other speculative purposes.

We believe that our use of derivatives and related hedging activities reduces our exposure to foreign currency exchange rate risk and does not expose us to material credit risk or any other material market risk.

All our derivatives mature during the next 18 months.

Property and equipment held-for-sale is recorded at the lower of net book value or fair value less cost to sell.

During 2019 , we recorded a pre-tax, non-cash loss on impairment of $98.4 million related to one floater and one jackup rig, both of which are older, less capable, non-core assets in our fleet.

We estimate the aforementioned impairment will cause a decline in depreciation expense of approximately $8.6 million for the year ended December 31, 2020 .

During 2020, we recorded an aggregate pre-tax, non-cash impairment of $3.6 billion with respect to certain floaters, jackups and spare equipment.

We estimate the portion of the aforementioned impairment related to

impaired rigs that remain in our fleet as of December 31, 2020 will cause a decline in depreciation expense of approximately $35.4 million for the year ended December 31, 2021.

Our fleet of 16 floater rigs, excluding two rigs under construction, represented 54% of the gross cost and 55% of the net carrying amount of our depreciable property and equipment as of December 31, 2020.

Our floater rigs are depreciated over useful lives ranging from 10 to 35 years.

Our fleet of 50 jackup rigs, represented 31% of both the gross cost and of the net carrying amount of our depreciable property and equipment as of December 31, 2019 .

Our jackup rigs are depreciated over useful lives ranging from 10 to 30 years.

Our fleet of 36 jackup rigs, represented 37% of the gross cost and 36% of the net carrying amount of our depreciable property and equipment as of December 31, 2020.

Our floater rigs and jackup rigs are depreciated over 35 and 30 years, respectively, for newly constructed assets and over their estimated remaining useful lives for rigs obtained in a business combination.

The following table provides an analysis of estimated increases and decreases in depreciation expense from continuing operations that would have been recognized for the year ended December 31, 2020 for various assumed changes in the useful lives of our drilling rigs effective January 1, 2020:

We collect and analyze the above information to develop a range of estimated utilization levels, day rates, expense levels and capital requirements, as well as estimated cash flows generated upon disposition.

The most subjective assumptions that impact our impairment analyses include projections of future oil prices and timing of global rig fleet attrition, which, in large part, impact our estimates on timing and magnitude of recovery from the current industry downturn.

The drivers of these assumptions that impact our impairment analyses include projections of future oil prices and timing of global rig fleet attrition, which, in large part, impact our estimates on timing and magnitude of recovery from the current industry downturn.

However, there are numerous judgments and assumptions unique to the projected future cash flows of each rig that individually, and in the aggregate, can significantly impact the recoverability of its carrying value.

Our pension and other postretirement benefit liabilities and costs are based upon actuarial computations that reflect our assumptions about future events, including long-term asset returns, interest rates, annual compensation increases, mortality rates and other factors.

Key assumptions at December 31, 2019 , included (i) a weighted average discount rate of 3.16% to determine pension benefit obligations, (ii) a weighted average discount rate of 3.82% to determine net periodic pension cost and (iii), an expected long-term rate of return on pension plan assets of 6.48% .

Key assumptions at December 31, 2020, included (1) a weighted average discount rate of 2.30% to determine pension benefit obligations, (2) a weighted average discount rate of 3.16% to determine net periodic pension cost and (3), an expected long-term rate of return on pension plan assets of 6.48% to determine net periodic pension cost.

The assumed discount rate is based upon the average yield for Moody’s Aa-rated corporate bonds, and the rate of return assumption reflects a probability distribution of expected long-term returns that is weighted based upon plan asset allocations.

1 unchanged sentence

To develop the expected long-term rate of return on assets assumption, we considered the current level of expected returns on risk-free investments (primarily government bonds), the historical level of the risk premium associated with the plans’ other asset classes, and the expectations for future returns of each asset class.

The expected return for each asset class was then weighted based upon the current asset allocation to develop the expected long-term rate of return on assets assumption for the plan, which was 6.48% at December 31, 2019 .
