We are one of thea leading providersprovider of offshore contract drilling services to the international oil and gas industry.industry with operations in almost every major offshore market across six continents. We currently own and operate anthe world's largest offshore drilling rig fleet, of 62 rigs, with drilling operations in most of the strategic markets around the globe. We also have three rigs under construction. Our rig fleet includes12 drillships, 11 dynamically positioned semisubmersible rigs, four moored semisubmersible rigs and 38 jackup rigs, including rigs under construction.  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. We currently own 53 rigs, including 13 drillships, four dynamically positioned semisubmersible rigs, one moored semisubmersible rig, 35 jackup rigs and a 50% equity interest in ARO, our 50/50 unconsolidated joint venture with Saudi Aramco, which owns an additional eight rigs.


Our customers include many of the leading nationalinternational and internationalgovernment-owned oil and gas companies, in addition to many independent operators. We are among the most geographically diverse offshore drilling companies with current operations spanning 14 countries on six continents.global operations. The markets in which we operate include the U.S. Gulf of Mexico, Brazil, the Mediterranean,South America, the North Sea, the Middle East, West Africa Australia and Southeast Asia.Asia Pacific.


We provide drilling services on a "day rate"day rate contract basis. Under day rate contracts, we provide an integrated service that includes the provision of a drilling rig and rig crews for which we receive a daily rate that may vary between the full rate and zero rate throughout the duration of the contractual term. The day rate we earn can vary between the full day rate and zero rate,term, depending on the operations of the rig. We also may receive lump-sum fees or similar compensation for the mobilization, demobilization and capital upgrades of our rigs. 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. In addition, our customers may pay all or a portion of the cost of moving our equipment and personnel

Demand for offshore drilling services continues to and from the well site.

Atwood Merger

On October 6, 2017 (the "Merger Date"), we completed a merger transaction (the "Merger") with Atwood Oceanics, Inc. ("Atwood") and Echo Merger Sub, LLC, a wholly-owned subsidiary of Ensco plc. Pursuant to the merger agreement, Echo Merger Sub, LLC, merged with and into Atwood, with Atwood as the surviving entity and an indirect, wholly-owned subsidiary of Ensco plc. Total consideration delivered in the Merger consisted of 132.2 million of our Class A ordinary shares and $11.1 million of cash in settlement of certain share-based payment awards. The total aggregate value of consideration transferred was $781.8 million. Additionally, upon closing of the Merger, we utilized cash acquired of $445.4 million and cash on hand to extinguish Atwood's revolving credit facility, outstanding senior notes and accrued interest totaling $1.3 billion. The estimated fair values assigned to assets acquired net of liabilities assumed exceeded the consideration transferred, resulting in a bargain purchase gain of $140.2 million that was recognized during the fourth quarter.

Drilling Rig Construction and Delivery

We remain focused on our long-established strategy of high-grading our fleet,improve as evidenced by the recently completed Merger. During the three-year period ended December 31, 2017, we invested approximately $1.9 billion in the construction of newincreasing global utilization and day rates for offshore drilling rigs. We will continue to invest in the expansion and high-grading of our fleet or execute other strategic transactions to optimize our asset portfolio when we believe attractive opportunities exist.



We believe our remaining capital commitments will primarily be funded from cash and cash equivalents, short-term investments, operating cash flows and, if necessary, funds borrowed under our revolving credit facility. We may decide to access debt and/or equity markets to raise additional capital or increase liquidityIn recent years, oil prices have experienced significant volatility as necessary.

Floaters

We previously entered into agreements with Samsung Heavy Industries to construct three ultra-deepwater drillships (ENSCO DS-8, ENSCO DS-9 and ENSCO DS-10). During 2015, we accepted delivery of ENSCO DS-8 and ENSCO DS-9. ENSCO DS-8 commenced drilling operations under a long-term contract in Angola during 2015 and ENSCO DS-9 is actively being marketed. During 2017, we executed a one-year contract with five one-year priced options for ENSCO DS-10. As a result of the contract award, we accelerated deliveryglobal COVID-19 pandemic, production disputes among major oil producing countries and various other factors. This volatility meaningfully impacted both the supply of, ENSCO DS-10, which had previously been deferred into 2019, and madedemand for, offshore rigs. Since 2021, oil prices have become relatively more stable due to, among other factors, rebounding demand for hydrocarbons, a measured approach to production increases by OPEC+ members, reduction in supply due to Russia’s invasion of Ukraine and the final milestone paymentsubsequent sanctions placed on Russia, and a focus on cash flow and returns by major exploration and production companies. In 2023, prices have remained at levels that are supportive of $75.0 million. We expect ENSCO DS-10offshore exploration and development activity. The more constructive oil price environment has led to commence drilling operations offshore Nigeriaan improvement in March 2018.contracting and tendering activity for our industry.


In connection with the Merger, we acquired two ultra-deepwater drillships, ENSCO DS-13 (formerly Atwood Admiral) and ENSCO DS-14 (formerly Atwood Archer), which are currently under constructionRig attrition in the Daewoo Shipbuilding & Marine Engineering Co. Ltd. ("DSME") yardindustry over the last decade, particularly for floaters, has resulted in South Korea. ENSCO DS-13 and ENSCO DS-14 are scheduled for delivery in the third quartera smaller global fleet of 2019 and second quarter of 2020, respectively. Upon delivery, the remaining milestone payments and accrued interest thereon may be financed through a promissory note with the shipyard for each rig. The promissory notes will bear interest at a rate of 5% per annum with a maturity date of December 31, 2022 and will be secured by a mortgage on each respective rig.

Jackups

During 2014, we entered into an agreement with Lamprell Energy Limited ("Lamprell")rigs that is available to construct two premium jackup rigs. ENSCO 140 and ENSCO 141 are significantly enhanced versions of the LeTourneau Super 116E jackup design and incorporate Ensco's patented Canti-Leverage AdvantageSM technology. ENSCO 140 and ENSCO 141 were delivered during 2016. Both rigs are expected to obtain drilling contracts for work commencing during 2018. As part ofmeet customer demands. Consequently, our agreement with Lamprell, these rigs will be warm stacked in the shipyard at no additional cost to us for up to two years from their respective delivery dates.

We previously entered into agreements with Keppel FELS ("KFELS") to construct four ultra-premium harsh environment jackup rigs (ENSCO 120, ENSCO 121, ENSCO 122 and ENSCO 123) and a premium jackup rig (ENSCO 110). ENSCO 120 and ENSCO 121 were delivered during 2013 and ENSCO 122 and ENSCO 110 were delivered during 2014 and 2015, respectively. During 2016, we agreed with the shipyard to delay delivery of ENSCO 123 until the first quarter of 2018. In December 2017, we agreed to further delay delivery of ENSCO 123 until the first quarter of 2019, and in January 2018, we paid $207.4 million of the $218.3 million unpaid balance with the remainder due upon delivery. ENSCO 123 is currently uncontracted and is actively being marketed.
Divestitures

Our business strategy has been to focus on ultra-deepwater floater and premium jackup operations and de-emphasize other assets and operations that are not part of our long-term strategic plan or that no longer meet our standards for economic returns. Consistent with this strategy, we sold nine jackup rigs, three dynamically positioned semisubmersible rigs, two moored semisubmersible rigs and two drillships during the three-year period ended December 31, 2017. We are marketing for sale ENSCO 7500, which was classified as held-for-sale in our consolidated financial statements as of December 31, 2017.

Following the Merger, we continue to focus on our fleet management strategy in light of the new composition of our rig fleet and are reviewing our fleet composition as we continue positioning Enscooutlook for the future. As part of this strategy, we may act opportunistically from time to time to monetize assets to enhance shareholder value and improve our liquidity profile, in addition to selling or disposing of older, lower-specification or non-core rigs.offshore drilling business is positive.




Contract Drilling Operations


Our business consists of threefour operating segments: (1) Floaters, which includes our drillships and semisubmersible rigs, (2) Jackups, (3) ARO and (3)(4) Other, which consists of management services on rigs owned by third-parties.

Our floater backlog declined $576.6 million primarily due to revenues realized during 2017, partially offset by contract extensions and new contract awards. The remaining $223.7 million decline primarily related to our jackups segment and was largely due to revenues realized during 2017, contract concessions and contract terminations, partially offset by contract extensions and new contract awards.
The following table summarizes our contract backlog of business as of December 31, 2017 and the periods in which such revenues are expected to be realized (in millions):

Our drilling contracts generally contain provisions permitting early termination of the contract (i) if the rig is lost or destroyed or (ii) by the customer if operations are suspended for a specified period of time due to breakdown of major rig equipment, unsatisfactory performance, "force majeure" events beyond the control of either party or other specified conditions.  In addition, our drilling contracts generally permit early termination of the contract by the customer for convenience (without cause), exercisable upon advance notice to us, and in some cases without making an early termination payment to us.  There can be no assurances that our customers will be able to or willing to fulfill their contractual commitments to us.  

The amount of actual revenues earned and the actual periods during which revenues are earned will be different from amounts disclosed in our backlog calculations due to a lack of predictability of various factors, including unscheduled repairs, maintenance requirements, newbuild rig delivery dates, weather delays, contract terminations or renegotiations and other factors.

See "Item 1A. Risk Factors - Our current backlog of contract drilling revenue may not be fully realized and may decline significantly in the future, which may have a material adverse effect on our financial position, results of operations and cash flows” and “Item 1A. Risk Factors - We may suffer losses if our customers terminate or seek to renegotiate our contracts, if operations are suspended or interrupted or if a rig becomes a total loss.”

Drilling Contracts and Insurance Program

Our drilling contracts provide for varying levels of allocation of responsibility for liability between our customer and us for loss or damage to each party's property and third-party property, personal injuries and other claims arising out of our drilling operations. We also maintain insurance for personal injuries, damage to or loss of property and certain business risks.
Our insurance policies typically consist of 12-month policy periods, and the next renewal date for a substantial portion of our insurance program is scheduled for May 31, 2018. Our insurance program provides coverage, subject to the policies' terms and conditions and to the extent not otherwise assumed by the customer under the indemnification provisions of the drilling contract, for third-party claims arising from our operations, including third-party claims arising from well-control events, named windstorms, sudden and accidental pollution originating from our rigs, wrongful death and personal injury. Third-party pollution claims could also arise from damage to adjacent pipelines and from spills of fluids maintained on the drilling unit. Generally, our program provides liability coverage up to $750.0 million, with a per occurrence deductible of $10.0 million or less. We retain the risk for liability not indemnified by the customer in excess of our insurance coverage.

Well-control events generally include an unintended flow from the well that cannot be contained by using equipment on site (e.g., a blowout preventer), by increasing the weight of drilling fluid or by diverting the fluids safely into production facilities. In addition to the third-party coverage described above, for claims relating to a well-control event, we also have $150.0 million of coverage available to pay costs of controlling and re-drilling of the well and third-party pollution claims.

Our insurance program also provides first party coverage to us for physical damage to, including total loss or constructive total loss of, our rigs, generally excluding damage arising from a named windstorm in the U.S. Gulf of Mexico. This coverage is based on an agreed amount for each rig and has a per occurrence deductible for losses ranging from $15.0 million to $25.0 million. Due to the significant premium, high deductible and limited coverage, we decided not to purchase first party windstorm insurance for our rigs in the U.S. Gulf of Mexico. Accordingly, we have retained the risk for windstorm damage to our six jackups and six floaters in the U.S. Gulf of Mexico.

Our drilling contracts customarily provide that each party is responsible for injuries or death to their respective personnel and loss or damage to their respective property (including the personnel and property of each parties’ contractors and subcontractors) regardless of the cause of the loss or damage. However, in certain drilling contracts our customer’s responsibility for damage to its property and the property of its other contractors contains an exception to the extent the loss or damage is due to our negligence, which exception is usually subject to negotiated caps on a


per occurrence basis, although in some cases we assume responsibility for all damages due to our negligence.  In addition, our drilling contracts typically provide for our customers to indemnify us, generally based on replacement cost minus some level of depreciation, for loss or damage to our down-hole equipment, and in some cases for a limited amount of the replacement cost of our subsea equipment, unless the damage is caused by our negligence, normal wear and tear or defects in our equipment.

Subject to the exceptions noted below, our customers typically assume most of the responsibility for and indemnify us from any loss, damage or other liability resulting from pollution or contamination arising from operations, including as a result of blowouts, cratering and seepage, when the source of the pollution originates from the well or reservoir, including costs for clean-up and removal of pollution and third-party damages. In most drilling contracts, we assume liability for third-party damages resulting from such pollution and contamination caused by our negligence, usually subject to negotiated caps on a per occurrence or per event basis. In addition, in substantially all of our contracts, the customer assumes responsibility and indemnifies us for loss or damage to the reservoir, for loss of hydrocarbons escaping from the reservoir and for the costs of bringing the well under control.  Further, subject to the exceptions noted below, most of our contracts provide that the customer assumes responsibility and indemnifies us for loss or damage to the well, except when the loss or damage to the well is due to our negligence, in which case most of our contracts provide that the customer's sole remedy is to require us to redrill the lost or damaged portion of the well at a substantially reduced rate and, in some cases, pay for some of the costs to repair the well.

Most of our drilling contracts incorporate a broad exclusion that limits the operator's indemnity for damages and losses resulting from our gross negligence and willful misconduct and for fines and penalties and punitive damages levied or assessed directly against us. This exclusion overrides other provisions in the contract that would otherwise limit our liability for ordinary negligence. In most of these cases, we are still able to negotiate a liability cap (although these caps are significantly higher than the caps we are able to negotiate for ordinary negligence) on our exposure for losses or damages resulting from our gross negligence. In certain cases, the broad exclusion only applies to losses or damages resulting from the gross negligence of our senior supervisory personnel. However, in some cases we have contractually assumed significantly increased exposure or unlimited exposure for losses and damages due to the gross negligence of some or all our personnel, and in most cases, we are not able to contractually limit our exposure for our willful misconduct.

Notwithstanding our negotiation of express limitations in our drilling contracts for losses or damages resulting from our ordinary negligence and any express limitations (albeit usually much higher) for losses or damages in the event of our gross negligence, under the applicable laws that govern certain of our drilling contracts, the courts will not enforce any indemnity for losses and damages that result from our gross negligence or willful misconduct. As a result, under the laws of such jurisdictions, the indemnification provisions of our drilling contracts that would otherwise limit our liability in the event of our gross negligence or willful misconduct are deemed to be unenforceable as being contrary to public policy, and we are exposed to unlimited liability for losses and damages that result from our gross negligence or willful misconduct, regardless of any express limitation of our liability in the relevant drilling contracts. Under the laws of certain jurisdictions, an indemnity from an operator for losses or damages of third parties resulting from our gross negligence is enforceable but an indemnity for losses or damages of the operator is not enforceable. In such cases, the contractual indemnity obligation of the operator to us would be enforceable with respect to third-party claims for losses of damages, such as may arise in pollution claims, but the contractual indemnity obligation of the operator to us with respect to injury or death to the operator's personnel, the operator’s damages to the well, to the reservoir and for the costs of well control would not be enforceable. Furthermore, although there is a lack of precedential authority for these types of claims in countries where the civil law is applied, in those situations where a fault based codified civil law system is applicable to our drilling contracts, as opposed to the common law system, the courts generally will not enforce a contractual indemnity clause that totally indemnifies us from losses or damages due to our gross negligence, but may enforce the contractual indemnity over and above a cap on our liability for gross negligence, assuming the cap requires us to accept a significant amount of liability.

Similar to gross negligence, regardless of any express limitations in a drilling contract regarding our liability for fines and penalties and punitive damages, the laws of most jurisdictions will not enforce an indemnity that indemnifies a party for a fine or penalty that is levied or punitive damages that are assessed directly against such party


on the ground that it is against public policy to indemnify a party from a fine and penalty or punitive damages, especially where the purpose of such levy or assessment is to deter the behavior that resulted in the fine or penalty or punish such party for the behavior that warranted the assessment of punitive damages.

The above description of our insurance program and the indemnification provisions of our drilling contracts is only a summary as of the date hereof and is general in nature. In addition, our drilling contracts are individually negotiated, and the degree of indemnification we receive from operators against the liabilities discussed above can vary from contract to contract, based on market conditions and customer requirements existing when the contract was negotiated and the interpretation and enforcement of applicable law when the claim is adjudicated. Notwithstanding a contractual indemnity from a customer, there can be no assurance that our customers will be financially able to indemnify us or will otherwise honor a contractual indemnity obligation that is enforceable under applicable law. Our insurance program and the terms of our drilling contracts may change in the future.

In certain cases, vendors who provide equipment or services to us limit their pollution liability to a specific monetary cap, and we assume the liability above that cap. Typically, in the case of original equipment manufacturers, the cap is a negotiated amount based on mutual agreement of the parties considering the risk profiles and thresholds of each party. However, for smaller vendors, the liability is usually limited to the value, or double the value, of the contract.

We generally indemnify the customer for legal and financial consequences of spills of waste oil, fuels, lubricants, motor oils, pipe dope, paint, solvents, ballast, bilge, garbage, debris, sewage, hazardous waste and other liquids, the discharge of which originates from our rigs or equipment above the surface of the water and in some cases from our subsea equipment. Our contracts generally provide that, in the event of any such spill from our rigs, we are responsible for fines and penalties.

Major Customers


We provide our contract drilling services to major international, government-owned and independent oil and gas companies. During 2017,the year ended December 31, 2023, our five largest customers accounted for 66%40% of consolidated revenues. Total, BP and Petrobras,plc, our largest customers,only customer who accounts for 10% or more of consolidated revenues, accounted for 22%, 15% and 11% of consolidated revenues, respectively.revenues.


Competition


The offshore contract drilling industry is highly competitive. Drilling contracts are, for the most part, awarded on a competitive bid basis. Price competition is often the primary factor in determining which contractor is awarded a contract, although quality of service, operational and safety performance, equipment suitability and availability, location of equipment, reputation and technical expertise also are factors.  There are numerous competitors

Non-U.S. Operations

Revenues from non-U.S. operations were 80%, 78%, 87% and 81% of our total consolidated revenues during the years ended December 31, 2023 and 2022, eight months ended December 31, 2021 (Successor), and four months ended April 30, 2021 (Predecessor), respectively.

See "Item 1A. Risk Factors - Our non-U.S. operations involve additional risks not associated with significant resourcesU.S. operations."

Insurance and Indemnification Matters

Our insurance program provides coverage, subject to the policies' terms and conditions and to the extent not otherwise assumed by the customer under the indemnification provisions of the drilling contract, for third-party liability claims arising from our operations. Our insurance program provides coverage that is customary for our industry. Generally, our insurance program provides third-party liability coverage up to $805.0 million. We retain the risk for liability not indemnified by the customer in excess of, and for risks not covered by, our insurance coverage.

Our insurance program also provides hull and machinery coverage for physical damage (including total loss) to our rigs, cargo and equipment, excluding damage arising from a named windstorm in the offshoreU.S. Gulf of Mexico. We separately purchase a small limit of named windstorm insurance for our floater rigs in the U.S. Gulf of Mexico. We currently carry limited insurance for loss of hire for several of our rigs.

Our customers typically indemnify us for most well-control events. Well-control events generally include an unintended release from a well that cannot be contained by using equipment on site, such as a blowout preventer, by increasing the weight of drilling fluid or by diverting the fluids safely into production facilities. Subject to the exceptions noted below, our customers typically assume most of the responsibility for and indemnify us from any loss, damage or other liability resulting from pollution or contamination arising from operations. Such pollution or contamination may be as a result of blowouts, cratering and seepage, when the source of the pollution originates from the well or reservoir. Such indemnities typically include costs for clean-up and removal of pollution and third-party damages.

Our drilling contracts customarily provide that each party is responsible for injuries or death to their respective personnel and loss or damage to their respective property (including the personnel and property of each parties’ contractors and subcontractors) regardless of the cause of the loss or damage. However, exceptions may exist as it relates to damages due to our negligence.  In addition, our drilling contracts typically provide for our customers to indemnify us, generally based on replacement cost minus some level of depreciation, for loss or damage to our down-hole equipment. In some cases, we are indemnified by our customer for a limited amount of the repair of or replacement cost of our subsea equipment. We also maintain insurance for exposures to personal injuries, damage to or loss of property and certain business risks.

We generally indemnify the customer for legal and financial consequences of spills of waste oil, fuels, lubricants, motor oils, pipe dope, paint, solvents, ballast, bilge, garbage, debris, sewage, hazardous waste and other liquids, the discharge of which originates from our rigs or equipment above the surface of the water and in some cases from our subsea equipment. Our contracts generally provide that, in the event of any such spill from our rigs, we are responsible for the related fines and penalties.

The above description of our insurance program and the indemnification provisions of our drilling contracts is only a summary as of the date hereof and is general in nature. In addition, our drilling contracts are individually negotiated, and the degree of indemnification we receive from operators against the liabilities discussed above can vary from contract to contract based on market conditions and customer requirements existing when the contract was negotiated and the interpretation and enforcement of applicable law when the claim is adjudicated. Our insurance program and the terms of our drilling industry.contracts may change in the future.


In certain cases, vendors who provide equipment or services to us limit their pollution liability to a specific monetary cap, and we assume the liability above that cap. Typically, in the case of original equipment manufacturers, the cap is a negotiated amount based on mutual agreement of the parties considering the risk profiles and thresholds of each party. However, for smaller vendors, the liability is usually limited to the value, or double the value, of the contract for the purchase of such equipment or services.

Additional information on insurance and indemnification matters and related risks is discussed in “Item 1A. Risk Factors,” which should be read in conjunction with the foregoing information.

Governmental Regulation and Environmental Matters


Our operations are affected by laws, regulations and political initiatives and by laws and regulations that relate to the oil and natural gas industry, including laws and regulations that have or may impose increased oil-spill related and financial responsibility and oil spill abatement contingency plan capability requirements. Accordingly, we will be directly affected by the approval and adoption of lawsLaws and regulations curtailing exploration and development drilling for oil and natural gas will directly affect us for economic, environmental, safety or other policy reasons. It is also possible that these laws, and regulations and political initiatives could adversely affect our operations in the future by significantly increasing our operating costs or restricting areas open for drilling activity.  See "ItemWe incorporate by reference herein the disclosures on governmental regulations, including environmental matters, contained in the following sections of this Annual Report on Form 10-K:

"Item 1A. Risk Factors- Increasing regulatory complexity could adversely impact the costs associated with our offshore drilling operations."Factors – Regulatory, Legal and Tax Risks";

"Item 1A. Risk Factors – Sustainability Risks";

"Item 3. Legal Proceedings"; and

"Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations – Liquidity and Capital Resources – Effects of Climate Change and Climate Change Regulation.
Our operations are subject to laws and regulations controlling the discharge of materials into the environment, pollution, contamination and hazardous waste disposal or otherwise relating to the protection of the environment. Environmental laws and regulations specifically applicable to our business activities could impose significant liability on us for damages, clean-up costs, fines and penalties in the event of oil spills or similar discharges of pollutants or contaminants into the environment or improper disposal of hazardous waste generated in the course of our operations, which may not be covered by contractual indemnification or insurance, or for which indemnity is prohibited by applicable law and could have a material adverse effect on our financial position, operating results and cash flows.  To date, such laws and regulations have not had a material adverse effect on our operating results, and we have not experienced an accident that has exposed us to material liability arising out of or relating to discharges of pollutants into the environment.  However, the legislative, judicial and regulatory response to any well-control incidents could substantially increase our customers' liabilities in respect of oil spills and also could increase our liabilities. In addition to potential increased liabilities, such legislative, judicial or regulatory action could impose increased financial, insurance or other requirements that may adversely impact the entire offshore drilling industry.

The International Convention on Oil Pollution Preparedness, Response and Cooperation, the International Convention on Civil Liability for Oil Pollution Damage 1992, the U.K. Merchant Shipping Act 1995, Marpol 73/78 (the International Convention for the Prevention of Pollution from Ships), the U.K. Merchant Shipping (Oil Pollution Preparedness, Response and Co-operation Convention) Regulations 1998, as amended, and other related legislation and regulations and the Oil Pollution Act of 1990 ("OPA 90"), as amended, the Clean Water Act and other U.S. federal statutes applicable to us and our operations, as well as similar statutes in Texas, Louisiana, other coastal states and other non-U.S. jurisdictions, address oil spill prevention, reporting and control and have significantly expanded potential liability, fine and penalty exposure across many segments of the oil and natural gas industry. Such statutes and related regulations impose a variety of obligations on us related to the prevention of oil spills, disposal of waste and liability for resulting damages. For instance, OPA 90 imposes strict and, with limited exceptions, joint and several liability upon each responsible party for oil removal costs as well as a variety of fines, penalties and damages. Similar environmental laws apply in our other areas of operation. Failure to comply with these statutes and regulations including OPA 90, may subject us to civil or criminal enforcement action, which may not be covered by contractual indemnification or insurance, or for which indemnity is prohibited under applicable law, and could have a material adverse effect on our financial position, operating results and cash flows.


High-profileAdditionally, climate change is receiving increasing attention from scientists and catastrophic events such as the 2010 Macondo well incident, have heightened governmentallegislators, and environmental concerns aboutsignificant focus is being put on companies in the oil and natural gas industry. FromGlobally, there are a number of legislative and regulatory proposals and executive orders at various levels of government in jurisdictions where we operate to address the GHG emissions that contribute to climate change, such as laws or regulations requiring reporting on GHG emissions, incentivizing or mandating the use of alternative energy sources such as wind power and solar energy, phasing-out of fossil fuel subsidies, reducing GHG emissions, increasing fuel efficiency standards, adopting carbon pricing mechanisms, restricting oil and gas development and programs to mandate or incentivize the conversion from internal combustion engine powered vehicles to electric-powered vehicles.

Although it is not possible at this time to time, legislative proposals have been introduced thatpredict how compliance with any such legislation or new regulations would materially limit or prohibit offshore drilling in certain areas.  We are adversely affected by restrictions on drilling in certain areas of the U.S. Gulf of Mexico and elsewhere, including the adoption of additional safety requirements and policies regarding the approval of drilling permits and restrictions on development and production activities in the U.S. Gulf of Mexico that have and may further impact our operations. 

As a result of Macondo, the Bureau of Safetybusiness, any such future laws and Environmental Enforcement ("BSEE") issued a drilling safety rule in 2012 that included requirements for the cementing of wells, well-control barriers, blowout preventers, well-control fluids, well completions, workovers and decommissioning operations. BSEEregulations could require us to incur increased operating costs or incremental capital expenditures. Any such legislation or regulatory programs could also issued regulations requiring operators to have safety and environmental management systems ("SEMS") prior to conducting operations and requiring operators and contractors to agree on how the contractors will assist the operators in complying with the SEMS. In addition, in August 2012, BSEE issued an Interim Policy Document ("IPD") stating that it would begin issuing Incidents of Non-Compliance ("INC's") to contractors as well as operators for serious violations of BSEE regulations. Following federal court decisions successfully challenging the scope of BSEE’s jurisdiction over offshore contractors, this IPD has been removed from the list of IPDs on the BSEE website. If this judicial precedent stands, it may reduce regulatory and civil litigation liability exposures.

In late 2014, the United States Coast Guard ("USCG") proposed new regulations that would impose GPS equipment and positioning requirements for mobile offshore drilling units and jackup rigs operating in the U.S. Gulf of Mexico and issued notices regarding the development of guidelines for cybersecurity measures used in the marine and offshore energy sectors for all vessels and facilities that are subject to the Maritime Transportation Security Act of 2002 ("MTSA"), including our rigs. The regulations imposing GPS equipment and positioning requirements have


not yet been issued.  On July 12, 2017, the USCG announced the availability of and requested comments on draft guidelines for addressing cyber risks at MTSA-regulated facilities. On July 28, 2016, BSEE adopted a new well-control rule that will be implemented in phases over the next several years (the "2016 Well Control Rule"). This new rule includes more stringent design requirements for well-control equipment used in offshore drilling operations. We are continuing to evaluateincrease the cost and effect that these new rules will have on our operations. Based on our current assessment of the rules, we do not expect to incur significant costs to comply with the 2016 Well Control Rule. The 2016 Well Control Rule is currently under review by BSEE pursuant to Executive Order (“EO”) 13783 (“Promoting Energy Independence and Economic Growth”) and Section 7 of EO 13795 (“Implementing an America-First Offshore Energy Strategy”), to determine if the rule should be revised to encourage energy exploration and production on the Outer Continental Shelf, while still providing for safe and environmentally responsible exploration and production activities.
The continuing and evolving threat of cyber attacks will likely require increased expenditures to strengthen cyber risk management systems for MODUs and onshore facilities. For example, on May 11, 2017, President Trump issued EO 13800, entitled Strengthening the Cybersecurity of Federal Networks and Critical Infrastructure, which is intended to improve the nation's ability to defend against increasing and evolving cyber attacks, and in July 2017 the USCG issued proposed cybersecurity guidelines for port facilities and offshore facilities, including mobile offshore drilling units, that could be impacted by cyber attacks. We cannot currently estimate the future expenditures associated with increased regulatory requirements, which may be material, and we continue to monitor regulatory changes as they occur.
If new laws are enacted or other government actions are taken that restrict or prohibit offshore drilling in our principal areas of operation or impose additional regulatory (including environmental protection) requirements that materially increase the liabilities, financial requirements or operating or equipment costs associated with offshore drilling, exploration, development or production ofconsuming oil and natural gas, and thereby reduce demand for oil and natural gas, which could reduce our customers’ demand for our services. Consequently, legislation and regulatory programs to reduce GHG emissions could have an adverse effect on our financial position, operating results and cash flows couldflows.

Sustainability

Consistent with our purpose of providing responsible solutions that deliver energy to the world, we are focused on sustainability-related matters. Our board of directors' Safety and Sustainability Committee regularly meets to address sustainability topics and is responsible for overseeing the Company’s policies, programs and practices related to sustainability and the Company’s management of risks in such areas. We have a dedicated department focused on sustainability and new energy and also have an employee-led cross-functional working group to identify and evaluate opportunities and promote sustainable business practices.

We publish our annual sustainability report aligned with the standards of the Task Force on Climate-Related Financial Disclosures (TCFD), in addition to the Sustainability Accounting Standards Board (SASB), with references to other frameworks such as the Global Reporting Initiative (GRI) and the Carbon Disclosure Project (CDP), where relevant, and report scope 1, 2 and 3 GHG emissions. For further discussion of sustainability-related risks and considerations see “Risk Factors” in Item 1A and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Item 7 of this Annual Report on Form 10-K.

We encourage you to review our latest Sustainability Report, located on our website (www.valaris.com), for more detailed information regarding our sustainability and human capital targets, including our GHG emissions intensity reduction target, programs and initiatives. Nothing on our website, including our Sustainability Report or sections thereof, shall be materially adversely affected.  See "Item 1A. Risk Factors - Compliancedeemed incorporated by reference into this Annual Report on Form 10-K or other filings that we make with or breachthe SEC.

Human Capital

We believe our people are one of environmental laws can be costly and could limit our operations." 

Non-U.S. Operations

Revenues from non-U.S. operations were 92%, 81% and 72%the most important elements of our total consolidated revenues during 2017, 2016success, and 2015, respectively.we benefit from a motivated, engaged, and diverse workforce. Our non-U.S. operationsapproach to attracting, developing, and shipyard rig constructionretaining a diverse workforce of high-performing talent is anchored in a long-term employment model that seeks to foster personal growth and enhancement projectsengagement.

Purpose and Culture

At Valaris, our purpose is to provide responsible solutions that deliver energy to the world. Our values are designed to guide us in support of our purpose:

Integrity – Doing the right thing; whether or not anyone is watching;
Safety – Causing no harm is always a priority;
Excellence – Delivering value to our customers while consistently raising the bar on performance;
Respect – Treating others the way we would like to be treated;
Ingenuity – Solving problems creatively; and
Stewardship – Safeguarding where we work for the next generation.
Our Ethics and Compliance Policy and our Code of Conduct (the “Code”) form the foundation of our compliance and ethics program, which provides guidance on how to uphold our values. We have translated the Code into nine different languages, making it widely accessible to our employees across the globe. We maintain an Ethics Hotline that is available to all employees, either online or by phone, to confidentially seek guidance or raise a concern.

The Code is reviewed on a periodic basis and approved by our board of directors. To further support our values of respect and integrity, we have policies prohibiting corruption, bribery (including facilitation payments), money laundering, retaliation, and reprisals for raising concerns, including those related to worker rights, working conditions, mistreatment, fraud, and misconduct. In addition, we have adopted a policy against modern slavery and human trafficking in our business and our supply chains.

Employees

We had a global workforce of approximately 5,985 persons including contractors, and approximately 4,261 persons excluding contractors, as of December 31, 2023. Our personnel represented 74 nationalities spread across 23 locations. The majority of our personnel work on our offshore installations and are compensated on an hourly basis. A portion of our employees and contractors working outside of the U.S. are represented under collective bargaining or similar agreements, which are subject to political, economicperiodic salary negotiation. As of December 31, 2023, women comprised 30% of our onshore employees and 1% of our offshore employees.

Employee Wellbeing and Engagement

We believe that one of the best ways to serve our customers is through creating a healthy, safe and engaging working and learning environment, where our employees are confident and comfortable to put their best work forward. We seek to promote a healthy environment by prioritizing the mental and physical health and other uncertainties, including:

terrorist acts, war and civil disturbances,

expropriation, nationalization, deprivation or confiscationneeds of our equipment oremployees while recognizing them for their achievements and accomplishments. For example, in most countries where we work, we offer an employee assistance program (“EAP”) to employees and their families. Our EAP provides access to counselors and other mental health professionals as well as discounts to fitness centers, financial guidance and other benefits in support of our customer's property,overall commitment to maintain a healthy workforce.




10



Feedback from our employees plays a key role in creating an agile, collaborative and trustworthy culture. We use surveys to measure employee engagement as well as our ability to align and execute around a common vision and foster innovation and creativity. These surveys help our leaders analyze the impact of company practices and culture on performance and have created a roadmap for improvement.

repudiation or nationalizationTraining and Retention

We are focused on developing talent and leadership among both our onshore and offshore employees. In 2021, we launched the Building Organizational Leadership (BOLD) training program. This program is designed to engage, support and provide leadership tools for our offshore supervisors, helping them assess and develop their team’s understanding and use of contracts,
our safety processes and policies. Approximately 492 personnel attended the program in 2023. We implemented an onshore leadership program in 2023, which included eight separate onshore leadership sessions, which was delivered to 157 personnel.

In 2023, 482 personnel completed the training program. The American Petroleum Institute’s Center for Offshore Safety recognized the Valaris Basic Training Center with the 2023 Safety Leadership Award.

Safety

Our policies set the expectation that causing no harm is a priority while conducting our operations. We seek to control major operational hazards with effective safeguards and to implement our management systems to protect the health and safety of our personnel.

Our Safe Systems of Work are designed with the aim of completing each job safely and efficiently:

Work Instruction – Step-by-step description of how to complete specific work activities, including mandatory precautions to be implemented;

Permit to Work – Formal authorization and control process for the safe execution of potentially hazardous work that may present risk to people, environment or other geographic areasassets;

Energy Isolation – Formal isolation of all energy sources before performing work on equipment;

Job Safety Analysis – Identification and control of job hazards before starting work; and

Stop Work Authority – Empowerment to stop work if a risk to people, environment or assets is perceived to exist.

As mentioned above, the Valaris Basic Training Program demonstrates our dedication to a safety-first work culture, and the ways in which we operate,implement our Safe Systems of Work into our work.

Emergence from Financial Restructuring

On August 19, 2020 (the “Petition Date”), Valaris plc (“Legacy Valaris” or “Predecessor”) and certain of its direct and indirect subsidiaries (collectively, the “Debtors”) filed voluntary petitions for reorganization under chapter 11 of the Bankruptcy Code in the Bankruptcy Court under the caption In re Valaris plc, et al., Case No. 20-34114 (MI) (the “Chapter 11 Cases”). On March 3, 2021, the Bankruptcy Court confirmed the Debtors' chapter 11 plan of reorganization.

On April 30, 2021 (the "Effective Date"), we successfully completed our financial restructuring and together with the Debtors emerged from the UniversityChapter 11 Cases. Upon emergence from the Chapter 11 Cases, we eliminated $7.1 billion of Ottawa.debt and obtained a $520 million capital injection by issuing the first lien secured notes (the "First Lien Notes"). See “Note 8 - Debt" to our consolidated financial statements included in "Item 8. Financial Statements and Supplementary Data" for additional information on the First Lien Notes. On the Effective Date, the Legacy Valaris Class A ordinary shares were cancelled and common shares of Valaris with a nominal value of $0.01 per share (the “Common Shares”) were issued. Also, former holders of Legacy Valaris' equity were issued warrants (the "Warrants") to purchase Common Shares.

Item 1A.Risk Factors

Risks Related to Our Business, Operations, Financing Arrangements and Market Conditions

The success of our business largely depends on the level of activity in theoffshore oil and natural gas industry,exploration, development and production, which can be significantly affected by volatile oil and natural gas prices.


The success of our business largely depends on the level of activity in offshore oil and natural gas exploration, development and production. Oil and natural gas prices, and market expectations of potential changes in these prices, significantly affect the level of drilling activity. Historically, when drilling activity and operator capital spending decline,declines, utilization and day rates also decline and drilling may be reduced or discontinued, resulting in an oversupply of drilling rigs. The oversupply of drilling rigs will be exacerbated by the entry of newbuild rigs into the market. Oil and natural gas prices have historically been volatile, and have declined significantly from prices in excess of $100 since mid-2014 causing operators to reduce capital spending and cancel or defer existing programs, substantially reducing the opportunities for new drilling contracts. Oil prices have rebounded off the 12-year lows experienced during early 2016, and during 2017 have experienced the first increase in average prices since 2014, with prices ranging from a low of $44 to $67 per barrel. While commodity prices have improved, they have not improved to a level that supports increased rig demand sufficient to absorb existing rig supply and generate meaningful increases in day rates. We expect these trends to continue as long as commodity prices and rig supply remain at current levels. The lack of a meaningful recovery of oil and natural gas prices or further price reductions or volatility in prices, may cause our customers to maintain historically low levels or further reduce their overall level of activity, in which case demand for our services may further decline and revenues may continue to be adversely affected through lower rig utilization and/or lower day rates.  decline.

Numerous factors may affect oil and natural gas prices and the level of demand for our services, including:


regional and global economic conditions and changes therein, including recessions,

oil and natural gas supply and demand, which is affected by worldwide economic activity and population growth,

expectations regarding future energy prices,

the desire and ability of the Organization of Petroleum Exporting Countries ("OPEC")OPEC+, its members and other oil-producing nations, such as Russia, to reach further agreements to set and maintain production levels and pricing and to implement existing and future agreements,

the availability of capital for oil and natural gas participants, including our customers, and capital allocation decisions by our customers, including the relative economics of offshore development versus onshorealternative prospects,

the level of production by non-OPEC countries,

U.S. and non-U.S. tax policy, including the U.K. windfall tax on oil and gas producers in the British North Sea,

advances in exploration and development technology, including with respect to onshore shale,

costs associated with exploring for, developing, producing and delivering oil and natural gas,

the rate of discovery of new oil and natural gas reserves and the rate of decline of existing oil and gas reserves,

investors reducing, or ceasing to provide, funding to the oil and natural gas industry in response to initiatives to limit climate change,


laws and government regulations that limit, restrict or prohibit exploration and development of oil and natural gas in various jurisdictions, or materially increase the cost of such exploration and development,

the development and exploitation of alternative fuels
or energy sources, resulting in reduced capital spending by our customers on oil and natural gas projects, and increased demand for electric-powered products, including electric-powered vehicles,

disruption to exploration and development activities due to hurricanes and other severeadverse weather conditions and the risk thereof,

natural disasters or incidents resulting from operating hazards inherent in offshore drilling, such as oil spills, and

the worldwide military or political environment, including the invasion of Ukraine by Russia and the conflict in the Middle East and any related political or economic responses, global macroeconomic effects of trade disputes and increased tariffs and sanctions and uncertainty or instability resulting from an escalation or additional outbreak of armed hostilities or other crises in oil or natural gas producing areas of the Middle East or geographic areas in which we operate, or acts of terrorism.terrorism, and

16


Despite significant declines in capital spending and cancelled or deferred drilling programs by many operators since 2015, oil and gas production has not yet been reduced by amounts sufficient to result in a rebound in pricing to levels seen prior to the current downturn, and we may not see sufficient supply reductions or a resulting rebound in pricing for an extended period of time. Further, the recent agreements of OPEC and certain non-OPEC countries to freeze and/or cut production may not be fully realized. The lack of actual production cuts or freezes, or the perceived risk that OPEC countries may not comply with such agreements, may result in depressed commodity prices for an extended period of time.

In addition, continued hostility in foreign countries and the occurrence or threat of terrorist attacks against the United Statesepidemic or other countries could create downward pressure on the economies of the United Statespandemic diseases and other countries. Moreover, higherany government response to such occurrence or threat.

Higher commodity prices may not necessarily translate into increased activity, however, and even during periods of high commodity prices, customers may cancel or curtail their drilling programs, or reduce their levels of capital expenditures for exploration and production for a variety of reasons, including their expectations for future oil and natural gas prices, the cost of exploration efforts, extended periods of price volatility, their lack of success in exploration efforts. Advances in onshore explorationefforts and development technologies, particularly with respect to onshore shale, could also result in our customers allocating more of theirre-allocating capital expenditure budgets to onshore exploration and production activities and less to offshore activities. expenditures for renewable energy projects.

These factors could cause our revenues and profits to decline further, as a result of declines in utilization and day rates, and limit our future growth prospects. Any significant decline in day rates or utilization of our drilling rigs particularly our high-specification floaters, could materially reduceadversely affect our revenuesfinancial position, operating results and profitability.cash flows. In addition, these risks could increase instability in the financial and insurance markets and make it more difficult for us to access capital and obtain insurance coverage that we consider adequate or are otherwise required by our contracts.


The offshore contract drilling industry historically has beenis highly competitive and cyclical, with periods of low demand and excess rig availability that could result in adverse effects on our business.cyclical.


Our industry is highly competitive, and our contracts are traditionally awarded on a competitive bid basis. Pricing, safety records and competency are key factors in determining which qualified contractor is awarded a job.contract. Rig availability, location and technical capabilities also can be significant factors in the determination. If we are not able to compete successfully, our revenues and profitability may be reduced.decline.


TheDemand for offshore contract drilling industry historically has been veryservices is highly cyclical, andwhich is primarily related todriven by the demand for drilling rigs and the available supply of drilling rigs. Demand for drilling rigs is directly related todriven by the regional and worldwide levels of offshore exploration and development spendingconducted by oil and natural gas companies, which is beyond our control. Offshore explorationcontrol and development spending may fluctuate substantially from year-to-year and from region-to-region.

The supply of offshore drilling rigs has increased significantly in recent years. Delivery of newbuild drilling rigs has increased and will continue to increase rig supply and could curtail a strengthening, or trigger a further reduction, in utilization and day rates. Currently, there are approximately 135 competitive newbuild drillships, semisubmersibles


and jackup rigs reported to be on order or under construction with delivery expected by the end of 2020.  Approximately 83 of these rigs are scheduled for delivery during 2018, representing an approximate 13% increase in the total worldwide fleet of competitive offshore drilling rigs since year-end 2017. Many of these offshore drilling rigs do not have drilling contracts in place. In addition, the supply of marketed offshore drilling rigs could further increase due to depressed market conditions resulting in an increase in uncontracted rigs as existing contracts expire. There are no assurances that the market in general or a geographic region in particular will be able to fully absorb the supply of new rigs in future periods.

The significant decline in oil and gas prices and resulting reduction in spending by our customers, together with the increase in supply of offshore drilling rigs in recent years, has resulted in an oversupply of offshore drilling rigs and a decline in utilization and day rates, a situation which may persist for many years.

Such a prolonged periodProlonged periods of reduced demand and/or excess rig supply have required us, and may in the future require us, to idle, sell or scrap additional rigs and enter into low day rate contracts or contracts with unfavorable terms. There can be no assurance that the current demand for drilling rigs will increase in the future.future or that any short-term improvement to market conditions will be sustained. Any further decline in demand for drilling rigs or a continued oversupply of drilling rigs could materially adversely affect our financial position, operating results or cash flows.


Our current backlog of contract drilling revenue may not be fully realized and may decline significantly in the future.

As of February 15, 2024 and February 21, 2023, our contract backlog was approximately $3.9 billion and $2.5 billion, respectively. This amount reflects the remaining contractual terms multiplied by the applicable contractual day rate. The contractual revenue may be higher than the actual revenue we ultimately receive because of a number of factors, including rig downtime or suspension of operations.

Several factors could cause rig downtime or a suspension of operations, many of which are beyond our control, including the early termination, repudiation or renegotiation of contracts, breakdowns of equipment, work stoppages, including labor strikes, shortages of material or skilled labor, surveys or inspections by government and maritime authorities, inability to obtain the requisite permits or approvals, periodic classification surveys, severe weather, strong ocean currents or harsh operating conditions, the occurrence or threat of epidemic or pandemic diseases, and any government response to such occurrence or threat and force majeure events.

17


Our customers may seek to terminate, repudiate or renegotiate our drilling contracts for various reasons, including in the event of damage or a total loss of the drilling rig, the suspension or interruption of operations for extended periods due to breakdown of major rig equipment, failure to comply with performance conditions or equipment specifications, the failure of the customer to receive final investment decision (FID) with respect to projects for which the drilling rig was contracted or other reasons and “force majeure” events beyond the control of either party or other specific conditions. Generally, our drilling contracts permit early termination of the contract by the customer for convenience (without cause), exercisable upon advance notice to us, and in certain cases without making an early termination payment to us. In cases where customers are required to make an early termination payment, such payments would provide some level of compensation to us for the lost revenue from the contract but in many cases would not fully compensate us for all of the lost revenue. There can be no assurances that our customers will be able to or willing to fulfill their contractual commitments to us.

A decline in oil and natural gas prices and any resulting downward pressure on utilization may cause some customers to consider early termination of select contracts despite having to pay onerous early termination fees in certain cases. Customers may request to renegotiate the terms of existing contracts, or they may request early termination or seek to repudiate contracts. In addition, financially distressed customers may seek to negotiate reduced termination fees as part of a restructuring package. Furthermore, as contracts expire, we may be unable to secure new contracts for our drilling rigs. Therefore, revenues recorded in future periods could differ materially from our current backlog. Our inability to realize the full amount of our contract backlog or to secure a new contract with substantially similar terms on a timely basis could materially adversely affect our financial position, operating results or cash flows.

Our business will be materially adversely affected if we are unable to secure contracts on economically favorable terms.terms or if option periods in existing contracts are not exercised as expected.


Our ability to renew expiring contracts or obtain new contracts and the terms of any such contracts will depend on market conditions. In December 2023, we took delivery of VALARIS DS-13 and VALARIS DS-14 (the "Newbuild Drillships") for an aggregate purchase price of approximately $337.0 million, which are currently uncontracted. Our customers’ decisions to exercise option periods resulting in additional work for the rig under contract also depend on market conditions. We may be unable to renew our expiring contracts, including contracts expiring due to a failure by the customer to exercise option periods, or obtain new contracts for the Newbuild Drillships or the drilling rigs under contracts that have expired or have been terminated, andterminated. In addition, the day rates under any new contracts or any renegotiated contracts may be substantially below the existing day rates, which could materially adversely affect our revenues and profitability.

Our three rigs under construction, which are scheduled for delivery between 2019 and 2020, are currently uncontracted. There is no assurance that we will secure drilling contracts for these rigs, or future rigs we construct or acquire, or that the drilling contracts we may be able to secure will be based upon rates and terms that will provide a reasonable rate of return on these investments. Our failure to secure contracts for these rigs at day rates and terms that result in a reasonable return upon completion of construction may result in a material adverse effect on our financial position, operating results or cash flows.

We may If customers do not achieve the intended results from the Merger, andexercise option periods under contracts that we currently expect to be exercised, we may not be able to successfully integrate our operations with Atwood after the Merger. Failure to successfully integrate Atwood may adversely affect our future results, and consequently, the value of our shares.

We consummated the Mergerface increased idle time associated with the expectation that it would result in various benefits, including, among others,related rigs, as we may have difficulty securing additional work to cover the expansion of our asset base and creation of synergies. We closed the Merger on October 6, 2017, however, achieving the anticipated benefits of the Merger is subject to a number of uncertainties, including whether the Atwood business can be integrated in an efficient and effective manner.
While we have successfully merged companies into our operations in the past, the integration process could take longer than anticipated and could result in the loss of valuable employees, the disruption of our ongoing business, processes and systems or inconsistencies in standards, controls, procedures, practices, policies and compensation arrangements, any of which could adversely affect our ability to achieve the anticipated benefits of the Merger. Our combined operations could be adversely affected by issues attributable to Atwood’s historical operations that arose or are based on events or actions that occurred prior to the completion of the Merger.option periods. In addition, integrating Atwood’s employees and operations willwe may choose to stack idle rigs that are not under contract, which would require the time and attention of management, which may negatively impact our business. Events outside of our control, including changes in regulation and laws, could adversely affect our abilityus to realize the expected benefits from the Merger.incur stacking costs for such rigs.




Our customers may be unable or unwilling to fulfill their contractual commitments to us, including their obligations to pay for losses, damages or other liabilities resulting from operations under the contract.liabilities.


CertainSome of our customers aremay be subject to liquidity risk and such riskthat could lead them to seek to repudiate, cancel or renegotiate our drilling contracts or fail to fulfill their commitments to us under those contracts. These risks are heightened in periods of depressed market conditions. Our drilling contracts provide for varying levels of indemnification from our customers, including with respect to well-control, reservoir liability and pollution. Our drilling contracts also provide for varying levels of indemnification and allocation of liabilities between our customers and us with respect to loss or damage to property and injury or death to persons arising from the drilling operations we perform. Under our drilling contracts, liability with respect to personnel and property customarily is generally allocated so that we and our customers each assume liability for our respective personnel and property. Our customers have historically assumed most of the responsibility for, and indemnifyindemnified us from any loss, damage or other liability resulting from, pollution or contamination, including clean-up and removal, and third-party damages arising from operations under the contract when the source of the pollution originates from the well or reservoir, including those resulting from blow-outsblowouts or cratering of the well. However, we generallyregularly are required to assume a limited amount of liability for pollution damage caused by our negligence, which

liability generally has caps for ordinary negligence, with much higher caps or unlimited liability where the damage is caused by our gross negligence.negligence or willful misconduct. Notwithstanding a contractual indemnity from a customer, there can be no assurance that our customers will be financially able to assumefulfill their responsibility, or honor their indemnityindemnification obligations to us for such losses. In addition, under the laws of certain jurisdictions, such indemnities under certain circumstances are not enforceable if the cause of the damage was our gross negligence or willful misconduct. This could result in us having to assume liabilities in excess of those agreed in our contracts due to customer balance sheet or liquidity issues or applicable law.

We may suffer losses if our customers terminate or seek to renegotiate our contracts, if operations are suspended or interrupted or if a rig becomes a total loss.

In market downturns similar to the current environment, our customers may not be able to honor the terms of existing contracts, may terminate contracts even where there may be onerous termination fees, may seek to void or otherwise repudiate our contracts including by claiming we have breached the contract, or may seek to renegotiate contract day rates and terms in light of depressed market conditions. Since early 2015, we have renegotiated a number of contracts and received termination notices with respect to several of our rigs. Generally, our drilling contracts are subject to termination without cause or termination for convenience upon notice by the customer. In certain cases, our contracts require the customer to pay an early termination payment in the event of a termination for convenience (without cause). Such payment would provide some level of compensation to us for the lost revenue from the contract and in many cases would not fully compensate us for the lost revenue. Certain of our contracts permit termination by the customer without an early termination payment. Furthermore, financially distressed customers may seek to negotiate reduced termination payments as part of a restructuring package.

We are currently engaged in discussions with our customer for the ENSCO DS-8 drilling contract. Our experience with these discussions are that they can lead to a blend and extend arrangement, no change to the contract or termination according to the termination for convenience provisions of the contract. There can be no assurance that we will be able to come to an agreement with our customer to revise the commercial terms of the ENSCO DS-8 drilling contract or that the contract will not be terminated. If we negotiate a blend and extend arrangement with our ENSCO DS-8 customer, the contract term would be extended but the day rate would be reduced for all or some portion of the contract term. If we are unable to reach an agreement on revised mutually beneficial commercial terms, the parties will remain subject to the terms of the ENSCO DS-8 contract, which provide that if the contract were terminated by the customer for convenience, we would be paid daily termination fees through November 2020. For the first 90 days following any such termination, the daily termination fee paid by the customer would be equal to the then-current operating day rate. For the remaining term through November 2020, the daily termination fee would be equal to 75% of the then-current operating day rate. If the contract were terminated for convenience and the ENSCO DS-8 were re-contracted prior to November 2020 for a day rate less than the operating day rate, the customer would be obligated to compensate us for any difference between the re-contracted operating rate and the full operating day rate through the end of the ENSCO DS-8 contract. In accordance with these contract terms, if the drillship were to be re-contracted


after such a termination, we would not anticipate that our financial results would be materially impacted during the re-contracted period. While we believe that the ENSCO DS-8's technical capabilities and operational excellence make the drillship a marketable asset, should the drillship not be re-contracted after a termination for convenience, the reduction in day rate over the remaining term of the contract would be substantially offset by a reduction in operating costs, and we would expect no more than a $15 million per annum EBITDA impact for the remaining term through November 2020.

Drilling contracts customarily specify automatic termination or termination at the option of the customer in the event of a total loss of the drilling rig and often include provisions addressing termination rights or reduction or cessation of day rates if operations are suspended or interrupted for extended periods due to breakdown of major rig equipment, unsatisfactory performance, "force majeure" events beyond the control of either party or other specified conditions.

If a customer cancels a contract or if we terminate a contract due to the customer’s breach and, in either case, we are unable to secure a new contract on a timely basis and on substantially similar terms, or if a contract is disputed or suspended for an extended period of time or renegotiated, it could materially and adversely affect our financial position, operating results or cash flows.

We may incur impairments as a result of future declines in demand for offshore drilling rigs.

We evaluate the carrying value of our property and equipment, primarily our drilling rigs, when events or changes in circumstances indicate that the carrying value of such rigs may not be recoverable. The offshore drilling industry historically has been highly cyclical, and it is not unusual for rigs to be idle or underutilized for significant periods of time and subsequently resume full or near full utilization when business cycles change. Likewise, during periods in which rig supply exceeds rig demand, competition may force us to contract our rigs at or near cash break-even rates for extended periods of time.

During 2017, we recognized a pre-tax, non-cash loss on impairment of $182.9 million related to two floaters and one jackup rig, all of which are older, less capable, non-core assets in our fleet. During the three years ended December 31, 2017, we have recorded pre-tax, non-cash losses on impairment of long-lived assets and goodwill of $3.1 billion. Further asset impairments may be necessary if market conditions remain depressed for longer than we expect. We have no goodwill on our balance sheet as of December 31, 2017 and 2016. See Note 4 to our consolidated financial statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.


The loss of a significant customer or customer contract, as well as customer consolidation and changes to customer strategy, could materially adversely affect us.our business.


We provide our services to major international, government-owned and independent oil and natural gas companies.  During 2017,2023, our five largest customers accounted for 66%40% of our consolidated revenues, in the aggregate, with our largest customer representing 22%11% of our consolidated revenues.revenues and a significant percentage of our operating cash flows. Our financial position, operating results or cash flows may be materially adversely affected if any of our higher day rate contracts were terminated or renegotiated on less favorable terms or if a major customer terminates its contracts with us, fails to renew its existing contracts with us, requires renegotiation of our contracts or declines to award new contracts to us.


Some of our customers have consolidated and could continue to consolidate and could use their size and purchasing power to achieve economies of scale and pricing concessions. In addition, certain of our customers are increasingly focusing their business strategy on renewable energy projects and away from oil and natural gas exploration and production. Such customer consolidation and strategic transitions could result in reduced capital spending by such customers, decreased demand for our drilling services, loss of competitive position and negative pricing impacts. If we cannot maintain service and pricing levels for existing customers or replace such revenues with increased business activities from other customers, our financial position, operating results and cash flows could be materially adversely affected.

Our current backloglong-term contracts are subject to the risk of cost increases, which could adversely impact our profitability.

In general, our costs increase as the demand for contract drilling revenueservices and skilled labor increase, which may materially adversely affect our financial position, operating results or cash flows. Our long-term contracts are subject to inflationary factors such as increases in skilled labor costs, material costs and overhead costs. While some of our contracts include cost escalation provisions that allow changes to our day rate based on stipulated cost increases or decreases, the timing and amount earned from these day rate adjustments may differ from our actual increase in costs and many contracts do not allow for such day rate adjustments. During times of reduced demand, reductions in costs may not be fully realizedimmediate as portions of the crew may be required to prepare our rigs for stacking, after which time the crew members are assigned to active rigs or dismissed. Moreover, as our rigs are mobilized from one geographic location to another, the labor and may decline significantlyother operating and maintenance costs can vary significantly. In general, labor costs increase primarily due to higher salary levels in a particular geographic location and inflation. Equipment maintenance expenses fluctuate depending upon the type of activity a drilling rig is performing and the age and condition of the equipment, as well as the impact of supply chain disruptions and inflation on the costs of parts and materials. Contract preparation expenses vary based on the scope and length of contract preparation required.

Our network and systems, including rig operating systems and critical data, are subject to cybersecurity risk and technical disruptions.

Our business depends on technologies, systems and networks, including both operational technology and information technology (“IT”), to conduct our offshore operations and help run our financial and onshore operations functions, including the collection of payments from customers, payments to vendors and employees and storage of company records. Some of these systems are managed or provided by third-party service providers, including cloud platform or cloud software providers.
19



Cybersecurity incidents, including unauthorized access, social engineering (including phishing), malware (including ransomware), distributed denial-of-service attacks, identity compromise and technical disruptions could materially impact our IT and operational technology systems, including critical systems and infrastructure, and our data, as well as impact our third-party service providers on whom we rely. The risks associated with the failure of our systems and cyber incidents and attacks on our systems could include disruptions of certain systems on our rigs; other impairments of our ability to conduct our operations, including disruptions in our ability to make or receive payments and financial and onshore operating functions, loss of intellectual property, proprietary information, customer and vendor data or other sensitive information; corruption or unauthorized release of our or our customer’s critical data; disruption of our or our customers’ operations; and increased costs to prevent, respond to or mitigate cybersecurity events. Our business operations could be materially impacted by an incident or interruption of systems we rely on that originates from, or compromises, third‐party networks or devices, including those of our third‐party service providers. Any such incident or attack could result in injury to people, loss of control of, or damage to, our, or our customer’s, assets, downtime, and loss of revenue or harm to the environment. Any such incident or attack could also compromise our networks or our customers’ and vendors’ networks and the information stored there could be accessed, publicly disclosed, lost or stolen. Any such access, disclosure or other loss of information could result in significant fines, civil and/or criminal claims or proceedings.

Laws and regulations governing cybersecurity and data privacy and the unauthorized disclosure of confidential or protected information pose increasingly complex compliance challenges and potential costs, and any failure to comply with these data cybersecurity and privacy requirements or other applicable laws and regulations in this area could result in significant regulatory or other penalties and legal liability. Disruption to our operations and damage to our reputation could materially adversely affect our financial position, operating results or cash flows.

There can also be no assurance that our efforts, or the efforts of our partners and vendors, to invest in the future,protection of information technology infrastructure and data will prevent or identify incidents in our systems. While we have a cybersecurity program and incident response plan in place to prepare for, detect, respond to, mitigate and recover from the impact of these attacks, cyber-attacks may leverage previously unknown vulnerabilities, sophisticated new techniques and emerging technologies and, there can be no assurance that our response will be successful or effectively address the incident on a timely basis. As a result of a cybersecurity incident, we could suffer interruptions in our ability to manage our operations, which may materially adversely affect our business and financial results. In addition, we may incur large expenditures to investigate or remediate, to recover data, to repair or replace networks or information systems, or to protect against similar future events. Regardless of the specific nature of a cybersecurity incident, we could experience material operational impact, financial loss, legal liability, regulatory violations or reputational harm.

Rig reactivation, upgrade and enhancement projects are subject to risks, including delays and cost overruns, which could materially adversely affect our financial position, operating results or cash flows.

The costs required to reactivate a stacked rig and return the rig to drilling service are significant. Depending on the length of time that a rig has been stacked, we may incur significant costs to restore the rig to drilling capability, which may also include capital expenditures due to, among other things, technological obsolescence or an equipment overhaul of the rig. Stacked drilling rigs require expenditures to return these rigs to drilling service. In the future, market conditions may not justify these types of expenditures or enable us to operate our rigs profitably during the remainder of their economic lives. In addition, we may not recover the expenditures incurred to reactivate rigs through the associated drilling contract or otherwise. We can provide no assurance that we will have access to adequate or economical sources of capital to fund the return of stacked rigs to drilling service.

20


During periods of increased rig reactivation, upgrade and enhancement projects, shipyards and third-party equipment vendors may be under significant resource constraints to meet delivery obligations. Such constraints may lead to substantial delivery and commissioning delays, equipment failures and/or quality deficiencies. Furthermore, drilling rigs may face start-up or other operational complications following completion of upgrades or maintenance. Other unexpected difficulties, including equipment failures, design or engineering problems, could result in significant downtime at reduced or zero day rates or the cancellation or termination of drilling contracts.

Rig reactivation, upgrade, life extension and repair projects are subject to the risks of delay or cost overruns, including the following: failure of third-party equipment to meet quality and/or performance standards, delays in equipment deliveries or shipyard construction, shortages of materials or skilled labor, disruptions occurring as the result of pandemics and/or epidemics and related public health measures implemented by governments worldwide, damage to shipyard facilities, including damage resulting from fire, explosion, flooding, severe weather, terrorism, war or other armed hostilities, unforeseen design or engineering problems, including those relating to the commissioning of newly designed equipment, unanticipated actual or purported change orders, strikes, labor disputes or work stoppages, financial or operating difficulties of equipment vendors or the shipyard while enhancing, upgrading, improving or repairing a materialrig or rigs, unanticipated cost increases, foreign currency exchange rate fluctuations impacting overall cost, inability to obtain the requisite permits or approvals, client acceptance delays, disputes with shipyards and suppliers, latent damages or deterioration to hull, equipment and machinery in excess of engineering estimates and assumptions, claims of force majeure events, and additional risks inherent to shipyard projects in a non-U.S. location. These risks could result in the cancellation or termination of drilling contracts for which the drilling rig was contracted or reduce the likelihood that such drilling rigs will receive a drilling contract if not already contracted.

We make significant expenditures to meet customer requirements, maintain our fleet to comply with laws and the applicable regulations and standards of governmental authorities and organizations, or to expand our fleet, and we may be required to make significant expenditures to maintain our competitiveness.

We make substantial expenditures to maintain our fleet. These expenditures could increase as a result of changes in offshore drilling technology, the cost of labor and materials, customer requirements, fleet size, the cost of replacement parts for existing drilling rigs, the geographic location of the drilling rigs, length of drilling contracts, governmental regulations, maritime regulations and technical standards relating to safety, security or the environment, and industry standards.

Changes in offshore drilling technology, customer requirements for new or upgraded equipment, and competition within our industry may require us to make significant capital expenditures. In addition, changes in governmental regulations relating to decarbonization, environmental, emissions, safety or equipment standards, as well as compliance with standards imposed by maritime self-regulatory organizations, may require us to make additional unforeseen capital expenditures. In addition, commitments made by us, or our customers, to reduce emissions, or decarbonize, may require us to upgrade or retrofit our drilling rigs with additional equipment, less carbon intensive equipment or instrumentation. As a result, we may be required to take our drilling rigs out of service for extended periods of time, with corresponding losses of revenues, in order to make such alterations or to add such equipment. In the future, market conditions may not justify these expenditures or enable us to operate our drilling rigs profitably during the remainder of their economic useful lives.

Additionally, in order to expand our fleet, we may require additional capital in the future. If we are unable to fund capital requirements with cash flows from operations or proceeds from sales of non-core assets, we may be required to either incur additional borrowings or raise capital through the sale of debt or equity securities. Our ability to access the capital markets may be limited by our financial condition at the time, by restrictive covenants in our debt agreements, bye-laws and regulations and by adverse effectmarket conditions resulting from, among others, general economic conditions, contingencies and uncertainties that are beyond our control. Similarly, when lenders and institutional investors reduce, and in some cases cease to provide, funding to industry borrowers, the liquidity and financial condition of us and our customers can be adversely impacted. If we raise funds by issuing equity securities, existing shareholders may experience dilution, and if we raise funds by issuing additional debt securities,
21


we may have to pledge additional assets as collateral. Our failure to obtain the funds for necessary future capital expenditures could materially adversely affect our business and on our financial position, operating results or cash flows.


Failure to recruit and retain skilled personnel could materially adversely affect our business.

We require skilled personnel to operate our drilling rigs and to provide technical services and support for our business, and further rig reactivations will require that we hire additional skilled personnel. As demand for our services and the number of December 31, 2017, our contract backlog was approximately $2.8 billion, which representsactive drilling rigs has increased, competition for the labor required for drilling operations and construction projects has intensified, leading to shortages of qualified personnel in the industry. During periods of intensified competition, it is more difficult and costly to recruit, train and retain qualified employees, including in foreign countries that require a declinecertain percentage of $800.3 million since December 31, 2016. This amount reflectsnational employees. The most recent prolonged industry downturn and resulting reductions in offshore personnel wages further reduced the remaining contractual terms multiplied bynumber of qualified personnel available. Hiring qualified and experienced personnel with the applicable contractual day rate. The contractual revenuespecialized skills and qualifications required to operate an offshore drilling rig is difficult due to the competitive labor market and lack of experience. In the current environment where competition for labor is intense, we may be higher thanrequired to increase existing levels of compensation to stay competitive in retaining a skilled workforce.

In addition, new personnel that we hire may need to undergo training to develop the actual revenue we receive because of a number of factors, including rig downtime or suspension of operations. Several factors could cause rig downtime or a suspension of operations, many of which are beyond our control, including:

the early termination, repudiation or renegotiation of contracts,



breakdowns of equipment,

work stoppages, including labor strikes,

shortages of material or skilled labor,

surveys by government and maritime authorities,

periodic classification surveys,

severe weather, strong ocean currents or harsh operating conditions,

the occurrence or threat of epidemic or pandemic diseases or any government responseskills needed to such occurrence or threat, and

force majeure events.

Our customers may seek to terminate, repudiate or renegotiate our drilling contracts for various reasons. Generally, our drilling contracts permit early termination of the contract by the customer for convenience (without cause), exercisable upon advance notice to us, and in certain cases without making an early termination payment to us.perform their job duties. There can be no assurancesassurance that our customerstraining programs will be adequate for these purposes, which could expose us to operational hazards and risks. We may also incur additional training costs to ensure that new or promoted personnel have the right skills and qualifications.

We also are subject to potential legislative or regulatory action that may impact working conditions, paid time off or other conditions of employment, including mandated vaccination programs. These conditions could further increase our costs or limit our ability to fully staff and operate our drilling rigs.

The increases in employment costs cause an increase in operating expenses, with a resulting reduction in net income, and our ability to fully staff and operate our drilling rigs may be negatively affected.

Our shared service center may not create the operational efficiencies that we expect and may create risks relating to the processing of transactions and recording of financial information, which could materially adversely affect our financial condition, operating results or cash flows.

We have implemented a shared service center program pursuant to which we have outsourced certain finance, human resources, supply chain and IT functions. We have and will continue to align the design and operation of our financial control environment as part of our shared service center program. As part of this program, we are outsourcing, and will continue to outsource, certain accounting, payroll, human resources, supply chain and IT functions to a third-party service provider. The party that we utilize for these services may not be able to handle the volume of activity or willingperform the quality of service necessary to support our operations. The failure of the third-party to fulfill their contractual commitmentsits obligations could disrupt our operations. In addition, the move to us.

The declinea shared service environment, including our reliance on a third-party provider, may create risks relating to the processing of transactions and recording of financial information. We could experience a lapse in oil pricesthe operation of internal controls due to turnover, lack of legacy knowledge, inappropriate training and the resulting downward pressure on utilization has causeduse of a third-party provider, which could result in significant deficiencies or material weaknesses in our internal control over financial reporting and may continue to cause some customers to consider early termination of select contracts despite having to pay onerous early termination fees in certain cases. Customers may continue to request to renegotiate the terms of existing contracts, or they may request early termination or seek to repudiate contracts in some circumstances. Furthermore, as our existing contracts expire, we may be unable to secure new contracts for our rigs. Therefore, revenues recorded in future periods could differ materially from our current backlog. Our inability to realize the full amount of our contract backlog may have a material adverse effect onadversely affect our financial position, operating results or cash flows.

We may not realize the expected benefits of our ARO joint venture.

ARO, our 50/50 unconsolidated ARO joint venture and a provider of offshore drilling services, faces many of the same risks as we face. Operating through ARO, in which we have difficulty obtaininga shared interest, may result in our having less control over many decisions made with respect to projects, operations, safety, utilization, internal controls and other operating and financial matters. ARO may not apply the same controls and policies that we follow to manage our risks, and ARO’s controls and policies may not be as effective. As a result, operational, financial and control issues may arise, which could materially adversely affect our financial position, operating results or maintaining insurancecash flows. Additionally, in order to establish or preserve our relationship with our joint venture partner we may agree to risks and contributions of resources that are proportionately greater than the returns we could receive, which could reduce our income and return on our investment in ARO compared to what we may traditionally require in other areas of our business.

ARO’s income and accounts receivable are concentrated with Saudi Aramco. The loss of this customer, or a substantial decrease in demand by this customer for ARO’s services, would have a material adverse effect on ARO’s business, results of operations and financial condition, which could materially adversely affect our financial position, operating results or cash flows.

We have issued a 10-year shareholder notes receivable to ARO (the “Notes Receivable from ARO”), which are governed by the laws of Saudi Arabia. In the event of a dispute with ARO over the repayment of the Notes Receivable from ARO, our ability to enforce the payment obligations of ARO or to exercise other remedies are subject to several significant limitations, including that our ability to accelerate outstanding amounts under the Notes Receivable from ARO is subject to the consent of Saudi Aramco and that the Notes Receivable from ARO are governed by the laws of Saudi Arabia, and we are limited to the remedies available under Saudi law. In addition, our Notes Receivable from ARO are subordinated and junior in right of payment to ARO’s term loan described below, and as such, we may not be repaid the interest or principal amounts of the Notes Receivable from ARO.

We have a potential obligation to fund ARO for newbuild jackup rigs. The shareholder agreement governing the joint venture (the "Shareholder Agreement") specifies that ARO shall purchase 20 newbuild jackup rigs over an approximate 10-year period. The first two newbuild jackups were ordered in January 2020. The first rig, Kingdom 1, was delivered in the fourth quarter of 2023 and the second is expected to be delivered in the first half of 2024. ARO is expected to commit to orders for two additional newbuild jackups in the near term. There can be no assurance that the new jackup rigs will begin operations as anticipated.

The joint venture partners intend for the newbuild jackup rigs to be financed out of ARO's available cash on hand or from operations and/or funds available from third-party financing. In October 2023, ARO entered into a $359.0 million term loan to finance the remaining payments due upon delivery of the first two newbuild jackups and for general corporate purposes. Further, in the event ARO has insufficient cash 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. Beginning with the delivery of the second newbuild, each partner's commitment shall be reduced by the lesser of the actual cost of each newbuild rig, or $250.0 million, on a proportionate basis. Any required capital contributions we make could negatively impact our liquidity position and financial condition.

As a result of these risks, it may take longer than expected for us to realize the expected returns on our investment in ARO or such returns may ultimately be less than anticipated. Additionally, if we are unable to make any required contributions, our ownership in ARO could be diluted which could hinder our ability to effectively manage ARO and could materially adversely affect our financial position, operating results or cash flows.

23


Joint venture investments could be adversely affected by our joint venture partners’ actions, financial condition and liquidity and disputes between us and our joint venture partners.

We have made investments in joint ventures other than ARO. Such investments are subject to the risk that the other shareholders of the joint venture, who may have different business or investment strategies than us or with whom we may have a disagreement or dispute, may have the ability to block business, financial, or management decisions (such as the decision to distribute dividends or appoint members of management), which may be crucial to the success of our investment in the joint venture, or could otherwise implement initiatives which may be contrary to our interests. Our partners may be unable, or unwilling, to fulfil their obligations under the relevant agreements regarding such joint ventures (for example by non-contributing working capital or other resources), or may experience financial, operational, or other difficulties that may adversely impact our investment in a particular joint venture. In addition, our partners may lack sufficient controls and procedures which could expose us to risk. If any of the foregoing were to occur, such occurrence could materially adversely affect our financial position, operating results or cash flows.

We may pursue other joint ventures that we believe will enable us to further expand or enhance our business. Any such joint venture would be evaluated on a case-by-case basis, and its consummation would depend upon numerous factors, including identifying suitable opportunities that align with our business strategy, reaching agreement with the potential counterparty on acceptable terms, the receipt of any applicable regulatory and other approvals, and other conditions. Any such joint venture would involve various risks, including among others (1) difficulties related to integrating or managing applicable parts of a joint venture and unanticipated changes in customer and other third-party relationships subsequent to closing, (2) diversion of management’s attention from day-to-day operations, (3) failure to realize anticipated benefits, such as cost savings, revenue enhancements or business synergies, (4) the potential for substantial transaction expenses and (5) potential accounting impairment or actual diminution or loss of value of our investment if future on terms we find acceptablemarket, business or other conditions ultimately differ from our assumptions at the time any such transaction is consummated.

Our business involves operating hazards, and our insurance coverageand indemnities from our customers may not protect us against allbe adequate to cover any potential losses.

The drilling of the risksoil and natural gas wells involves numerous operating hazards, we face, including those specific to offshore operations.

Our operations are subject to hazards inherent in the offshore drilling industry, such as blow-outs,blowouts, reservoir damage, loss of production, loss of well-control,well control, uncontrolled formation pressures, lost or stuck drill strings, equipment failures and mechanical breakdowns, punchthroughs,punch throughs, craterings, industrial accidents, fires, explosions, oil spills and pollution. Contract drilling requires the use of heavy equipment and exposure to hazardous conditions, which may subject us to liability claims by employees, customers and other parties or prosecution by governmental authorities. These hazards can cause personal injury or loss of life, severe damage to, or destruction of, property and equipment, pollution or environmental damage, which could lead to claims by employees, contractors or third parties or customers,and suspension of operations and contract terminations. Our fleet isdrilling rigs are also subject to hazards inherent inassociated with marine operations, either while on-sitedocked, on site or during mobilization, such as capsizing, breaking free of moorings, sinking, grounding, collision, piracy, damage from severeadverse weather and marine life infestations. Additionally,The U.S. Gulf of Mexico and the coasts of Australia are areas subject to hurricanes, typhoons and other adverse weather conditions, and our drilling rigs in these regions may be exposed to damage or a security breachtotal loss by these storms, some of our information systems or other technological failure could lead to a material disruptionwhich may not be covered by insurance. The occurrence of our operations, information systems and/or loss of business information, whichthese events could result in an adverse impactthe suspension of drilling operations, damage to or destruction of the equipment involved and injury to or death of rig personnel. Operations may also be suspended because of machinery breakdowns, abnormal drilling conditions, failure of subcontractors to perform or supply goods or services or personnel shortages. Damage to the environment could also result from our business.operations, particularly through spillage of hydrocarbons, fuel, lubricants or other chemicals and substances used in drilling operations or fires. We may also be subject to property damage, environmental indemnity and other claims by third parties. Drilling involves certain risks associated with the loss of control of a well, such as blowout, cratering, the cost to regain control of or redrill the well and remediation of associated pollution. Our customers may be unable or unwilling to indemnify us against such risks. In addition, a court may decide that certain indemnities in our current or future drilling contracts provide for varying levels of indemnification from our customers, including with respect to well-control and subsurface risks. For example, most of our drilling contracts incorporate a broad exclusion that limits the customer'sare not enforceable. The law generally

considers contractual indemnity for damages and losses resulting from our gross negligence and willful misconduct and forcriminal fines and penalties to be against public policy, and punitive damages leviedthe enforceability of an indemnity as to other matters may be limited.

Our insurance policies and drilling contracts contain rights to indemnity that may not adequately cover our losses, and we do not have insurance coverage or assessed directly against us.rights to indemnity for all risks. We also maintainhave two main types of insurance coverage: (1) hull and machinery coverage for personal injuries,physical damage to or loss ofour property and equipment and other(2) excess liability coverage, which generally covers our liabilities arising from our operations, such as personal injury and property claims, including wreck removal and pollution. We have no hull and machinery insurance coverage for various business risks.damages caused by named storms in the U.S. Gulf of Mexico for our jack-up fleet and only limited coverage for our floater fleet. We also retain the risk for any liability that exceeds our excess liability coverage. Pollution and environmental risks generally are not completely insurable.


We generally identifyIf a significant accident or other event occurs that is not fully covered by our insurance or by an enforceable or recoverable indemnity, the operational hazards for which we will procureoccurrence could materially adversely affect our financial position, operating results or cash flows. The amount of our insurance may also be less than the related impact on enterprise value after a loss. Our insurance coverage based onwill not in all situations provide sufficient funds to protect us from all liabilities that could result from our drilling operations. Our coverage includes annual aggregate policy limits. As a result, we generally retain the likelihoodrisk for any losses in excess of these limits. We currently only carry limited insurance for loss the potential magnitude of loss, the cost of coverage, the requirementshire for several of our customer contracts

Any such lack of reimbursement may cause us to incur substantial costs. In addition, we could decide to retain more risk in the future, resulting in higher risk of losses, which could be material. Moreover, we may not be able to maintain what we believe to be an appropriate level ofadequate insurance covering hazards and risks we currently encounter during our operations, no assurance can be givenin the future at rates that we willconsider reasonable or be able to obtain insurance against all potential risks and hazards, or that we will be able to maintain the same levels and types of coverage that we have maintained in the past.

Our insurance policies may also have exclusions of coverage for some losses. Uninsured exposures may include radiation hazards, certain loss or damage to property onboard our rigsof hire and losses relating to shore-based terrorist acts or strikes.

Ifcover these risks. Additionally, a significant accidentnumber of high cost climate-related insurance claims or natural catastrophes such as hurricanes, floods or windstorms may result in withdrawal of insurance capacity and increasing premiums to oil and natural gas industry companies.

Geopolitical events and violence could materially adversely affect the markets for our services and have a material adverse effect on our business and cost and availability of insurance.

Geopolitical events have resulted in military actions, terrorist, pirate and other armed attacks, civil unrest, political demonstrations, mass strikes and government responses to such events. Military action by the U.S. or other event occursnations could escalate, and is not fully covered byacts of terrorism, piracy, kidnapping, extortion, acts of war, violence, civil war or general disorder may initiate or continue. Such acts could be directed against us or our assets. Such developments have caused instability in the world’s financial and insurance markets in the past. In addition, these developments could lead to increased volatility in prices for oil and natural gas and could materially adversely affect the markets for our services, particularly to the extent that such events take place in regions with significant oil and natural gas reserves, refining facilities or contractual indemnity (or if our contractual indemnity is not enforceable under applicable law), ittransportation infrastructure. For example, the ongoing conflicts, and the continuation of, or any increase in the severity of, the conflicts in Ukraine and the Middle East, has led and may continue to lead to an increase in the volatility of global oil and natural gas prices. Insurance premiums could increase and coverage for these kinds of events may be unavailable in the future. Any or all of these effects could materially adversely affect our financial position, operating results or cash flows.

The potential for U.S. Gulf of Mexico hurricane related windstorm damage or liabilities could result in uninsured losses and may cause us to alter our operating procedures during hurricane season, which could adversely affect our business.

Certain areas in and near the U.S. Gulf of Mexico experience hurricanes and other extreme weather conditions on a relatively frequent basis. Some of our drilling rigs in the U.S. Gulf of Mexico are located in areas that could cause them to be susceptible to damage and/or total loss by these storms, and we have a larger concentration of jackup rigs in the U.S. Gulf of Mexico than most of our competitors. We currently have six jackup rigs and six floaters in the U.S. Gulf of Mexico. Damage caused by high winds and turbulent seas could result in rig loss or damage, termination of drilling contracts for lost or severely damaged rigs or curtailment of operations on damaged drilling rigs with reduced or suspended day rates for significant periods of time until the damage can be repaired. Moreover, even if our drilling rigs are not directly damaged by such storms, we may experience disruptions in our operations due to damage to our customers' platforms and other related facilities in the area. Our drilling operations in the U.S. Gulf of Mexico have been impacted by hurricanes in the past, including the total loss of drilling rigs, with associated losses of contract revenues and potential liabilities.

Insurance companies incurred substantial losses in the offshore drilling, exploration and production industries as a consequence of hurricanes that occurred in the U.S. Gulf of Mexico during 2004, 2005 and 2008. Accordingly, insurance companies have substantially reduced the nature and amount of insurance coverage available for losses arising from named tropical storm or hurricane damage in the U.S. Gulf of Mexico and have dramatically increased the cost of available windstorm coverage. The tight insurance market not only applies to coverage related to U.S. Gulf of Mexico windstorm damage or loss of our drilling rigs, but also impacts coverage for any potential liabilities to third parties associated with property damage, personal injury or death and environmental liabilities, as well as coverage for removal of wreckage and debris associated with hurricane losses. We have no assurance that the tight insurance market for windstorm damage, liabilities and removal of wreckage and debris will not continue into the foreseeable future.

We do not purchase windstorm insurance for hull and machinery losses to our floaters arising from windstorm damage in the U.S. Gulf of Mexico due to the significant premium, high deductible and limited coverage for windstorm damage. We opted out of windstorm insurance for our jackups in the U.S. Gulf of Mexico during 2009 and have not since renewed that insurance. We believe it is no longer customary for drilling contractors with similar size and fleet composition to purchase windstorm insurance for rigs in the U.S. Gulf of Mexico for the aforementioned reasons. Accordingly, we have retained the risk of loss or damage for our six jackups and six floaters arising from windstorm damage in the U.S. Gulf of Mexico.



We have established operational procedures designed to mitigate risk to our jackup rigs in the U.S. Gulf of Mexico during hurricane season, and these procedures may result in a decision to decline to operate on a customer-designated location during hurricane season notwithstanding that the location, water depth and other standard operating conditions are within a rig's normal operating range. Our procedures and the associated regulatory requirements addressing Mobile Offshore Drilling Unit operations in the U.S. Gulf of Mexico during hurricane season, coupled with our decision to retain (self-insure) certain windstorm-related risks, may result in a significant reduction in the utilization of our jackup rigs in the U.S. Gulf of Mexico.

Our annual insurance policies are up for renewal effective May 31, 2018, and any retained exposures for property loss or damage and wreckage and debris removal or other liabilities associated with U.S. Gulf of Mexico tropical storms or hurricanes may have a material adverse effect on our financial position, operating results or cash flows if we sustain significant uninsured or underinsured losses or liabilities as a result of these storms or hurricanes.

Our non-U.S. operations involve additional risks not typically associated with U.S. operations.

Revenues from non-U.S. operations were 92%, 81% and 72% of our total revenues during 2017, 2016 and 2015, respectively. Our non-U.S. operations and shipyard rig construction and enhancement projects are subject to political, economic and other uncertainties, including:

terrorist acts, war and civil disturbances, 

expropriation, nationalization, deprivation or confiscation of our equipment or our customer's property, 

repudiation or nationalization of contracts, 

assaults on property or personnel, 

piracy, kidnapping and extortion demands, 


significant governmental influence over many aspects of local economies and customers,
25

unexpected changes in law and regulatory requirements, including changes in interpretation or enforcement of existing laws, 

work stoppages, often due to strikes over which we have little or no control,

complications associated with repairing and replacing equipment in remote locations, 

limitations on insurance coverage, such as war risk coverage, in certain areas,

imposition of trade barriers,

wage and price controls,

import-export quotas,

exchange restrictions, 

currency fluctuations, 

changes in monetary policies,

uncertainty or instability resulting from hostilities or other crises in the Middle East, West Africa, Latin America or other geographic areas in which we operate,



changes in the manner or rate of taxation, 

limitations on our ability to recover amounts due, 

increased risk of government and vendor/supplier corruption, 

increased local content requirements,

the occurrence or threat of epidemic or pandemic diseases or any government response to such occurrence or threat,

changes in political conditions, and 

other forms of government regulation and economic conditions that are beyond our control.

We historically have maintained insurance coverage and obtained contractual indemnities that protect us from some, but not all, of the risks associated with our non-U.S. operations such as nationalization, deprivation, expropriation, confiscation, political and war risks. However, there can be no assurance that any particular type of contractual or insurance protection will be available in the future or that we will be able to purchase our desired level of insurance coverage at commercially feasible rates.  Moreover, we may initiate a self-insurance program through one or more captive insurance subsidiaries.  In circumstances where we have insurance protection for some or all of the risks sometimes associated with non-U.S. operations, such insurance may be subject to cancellation on short notice, and it is unlikely that we would be able to remove our rig or rigs from the affected area within the notice period. Accordingly, a significant event for which we are uninsured, underinsured or self-insured, or for which we have not received an enforceable contractual indemnity from a customer, could cause a material adverse effect on our financial position, operating results or cash flows.

In June 2016, the U.K. voted to exit from the E.U. (commonly referred to as “Brexit”). The impact of Brexit and the resulting U.K./E.U. relationship are uncertain for companies doing business both in the U.K. and the overall global economy. Approximately 9% of our total revenues were generated in the U.K. for the year ended December 31, 2017. Brexit, or similar events in other jurisdictions, can impact global markets, including foreign exchange and securities markets, which may have an adverse impact on our business and operations as a result of changes in currency exchange rates, tariffs, treaties and other regulatory matters.

We are subject to various tax laws and regulations in substantially all countries in which we operate or have a legal presence. We evaluate applicable tax laws and employ various business structures and operating strategies to obtain the optimal level of taxation on our revenues, income, assets and personnel. Actions by tax authorities that impact our business structures and operating strategies, such as changes to tax treaties, laws and regulations, or the interpretation or repeal of any of the foregoing or changes in the administrative practices and precedents of tax authorities, adverse rulings in connection with audits or otherwise, or other challenges may substantially increase our tax expense.

As required by law, we file periodic tax returns that are subject to review and examination by various revenue agencies within the jurisdictions in which we operate. We cannot predict or provide assurance as to the ultimate outcome of existing or future tax assessments.

Our non-U.S. operations also face the risk of fluctuating currency values, which may impact our revenues, operating costs and capital expenditures. We currently conduct contract drilling operations in certain countries that have experienced substantial fluctuations in the value of their currency compared to the U.S. dollar. In addition, some of the countries in which we operate have occasionally enacted exchange controls. Generally, we have contractually mitigated these risks by invoicing and receiving payment in U.S. dollars (our functional currency) or freely convertible currency and, to the extent possible, by limiting our acceptance of foreign currency to amounts which approximate


our expenditure requirements in such currencies. However, not all of our contracts contain these terms and there is no assurance that our contracts will contain such terms in the future.

A portion of the costs and expenditures incurred by our non-U.S. operations, including certain capital expenditures, are settled in local currencies, exposing us to risks associated with fluctuation in the value of these currencies relative to the U.S. dollar. We use foreign currency forward contracts to reduce this exposure in certain cases. However, a relative weakening in the value of the U.S. dollar in relation to the local currencies in these countries may increase our costs and expenditures.

Our non-U.S. operations are also subject to various laws and regulations in countries in which we operate, including laws and regulations relating to the operation of drilling rigs and the requirements for equipment. We may be required to make significant capital expenditures to operate in such countries, which may not be reimbursed by our customers. Governments in some countries have become increasingly active in regulating and controlling the ownership of oil, natural gas and mineral concessions and companies holding concessions, the exploration of oil and natural gas and other aspects of the oil and gas industry in their countries. In some areas of the world, government activity has adversely affected the amount of exploration and development work performed by major international oil companies and may continue to do so. Moreover, certain countries accord preferential treatment to local contractors or joint ventures or impose specific quotas for local goods and services, which can increase our operational costs and place us at a competitive disadvantage. There can be no assurance that such laws and regulations or activities will not have a material adverse effect on our future operations.
The shipment of goods, services and technology across international borders subjects us to extensive trade laws and regulations. Our import activities are governed by specific customs laws and regulations in each of the countries where we operate. Moreover, many countries, including the United States, control the export and re-export of certain goods, services and technology and impose related export recordkeeping and reporting obligations. Governments also may impose express or de facto economic sanctions against certain countries, persons and other entities that may restrict or prohibit transactions involving such countries, persons and entities.

The laws and regulations concerning import activity, export recordkeeping and reporting, export control and economic sanctions are complex and constantly changing. These laws and regulations may be enacted, amended, enforced or interpreted in a manner materially impacting our operations. Shipments can be delayed and denied export or entry for a variety of reasons, some of which are outside our control and some of which may result from failure to comply with existing legal and regulatory regimes. Shipping delays or denials could cause unscheduled operational downtime, reduced day rates during such downtime and contract cancellations. Any failure to comply with applicable legal and regulatory trading obligations also could result in criminal and civil penalties and sanctions, such as fines, imprisonment, exclusion from government contracts, seizure of shipments and loss of import and export privileges.

Our employees, contractors and agents may take actions in violation of our policies and procedures designed to promote compliance with the laws of the jurisdictions in which we operate. Any such violation could have a material adverse effect on our financial position, operating results or cash flows.



Our drilling contracts with national oil companies may expose us to greater risks than we normally assume in drilling contracts with non-governmental customers.


We currently own and operate 1813 drilling rigs that are contracted with national oil companies. The terms of these contracts are often non-negotiable and may expose us to greater commercial, political and operational risks than we assume in other contracts, such as exposure to materially greater environmental liability, personal injury and other claims for damages (including consequential damages), or, in certain cases, the risk thatof early termination of the contract may be terminated by our customer without cause on short-termfor convenience (without cause), exercisable upon advance notice to us, contractually or by governmental action, under certain conditions that may not provide us withwithout making an early termination payment. payment to us. We can provide no assurance that the increased risk exposure will not have an adverse impact on our future operations or that we will not increase the number of drilling rigs contracted to national oil companies with commensurate additional contractual risks.


WeThe impact and effects of public health crises, pandemics and epidemics could have a material adverse effect on our business, financial condition and results of operations.

Public health crises, pandemics and epidemics and fear of such events may adversely impact our operations, the operations of our customers and the global economy, including the worldwide demand for oil and natural gas and the level of demand for our services. Other effects of such public health crises, pandemics and epidemics may include significant volatility and disruption of the global financial markets; continued volatility of crude oil prices and related uncertainties around OPEC+ production; disruption of our operations, including suspension of drilling activities; impact to costs; loss of workers; labor shortages; supply chain disruptions or equipment shortages; logistics constraints; customer demand for our services and industry demand generally; capital spending by oil and natural gas companies; our liquidity; the price of our securities and trading markets with respect thereto; our ability to access capital markets; asset impairments and other accounting changes; certain of our customers experiencing bankruptcy or otherwise becoming unable to pay vendors, including us; and employee impacts from illness, travel restrictions, including border closures and other community response measures. Such public health crises, pandemics and epidemics are continuously evolving and the extent to which our business operations and financial results may be affected depends on various factors beyond our control, such as the duration, severity and sustained geographic resurgence of public health crises, pandemics and epidemics; the impact and effectiveness of governmental actions to contain and treat such outbreaks, including government policies and restrictions; vaccine hesitancy, vaccine mandates, and voluntary or mandatory quarantines; and the global response surrounding such uncertainties.

Unionization efforts and labor regulations in certain countries in which we operate could materially increase our costs or limit our flexibility with regard to the management of our personnel.

Outside of the U.S., we are often subject to collective bargaining agreements that require periodic salary negotiations, which usually result in higher personnel expenses and other benefits. Efforts have been made from time to time to unionize other portions of our workforce. In addition, we have been subjected to strikes or work stoppages and other labor disruptions in certain countries. Additional unionization efforts, new collective bargaining agreements or work stoppages could materially increase our costs, reduce our profitability or suspendlimit our dividendflexibility.

Certain legal obligations require us to contribute certain amounts to retirement funds or other benefit plans and restrict our ability to dismiss employees. Future regulations or court interpretations established in the future.countries in which we conduct our operations could increase our costs and materially adversely affect our financial position, operating results or cash flows.

Significant equipment or part shortages, supplier capacity constraints, supplier production disruptions, supplier quality and sourcing issues or price increases could materially adversely affect our financial position, operating results or cash flows.

Our Board of Directors declared a $0.01 quarterly cash dividend per Class A ordinary share for each quarter during 2016reliance on third-party suppliers, manufacturers and 2017, a $0.14 reduction from the $0.15 dividend per share paid for each quarter during 2015. In the future, our Board of Directors may, without advance notice, further reduce or suspend our dividend in orderservice providers to improve our financial flexibilitysecure equipment, parts, components and best position us for long-term success. The declaration and amount of future dividends is at the discretion of our Board of Directors and will depend on our profitability, liquidity, financial condition, market outlook, reinvestment opportunities, capital requirements, restrictions and limitationssub-systems used in our credit facilityoperations exposes us to potential volatility in the quality, prices and other debt documentsavailability of such items. Certain high-specification parts and other factors and restrictions our Board of Directors deems relevant. There can be no assuranceequipment that we will payuse in our operations may be available only from a dividendsmall number of suppliers, manufacturers or service providers, or in some cases must be sourced through a single supplier, manufacturer or service provider. Industry consolidation has reduced and may continue to reduce the number of available suppliers, and our suppliers have been and may continue to be impacted by supply chain and logistics disruptions that began during the COVID-19 pandemic. A disruption in the future.

Legaldeliveries from such third-party suppliers, manufacturers or service providers, capacity constraints, production disruptions, price increases, including those related to inflation and regulatory proceedingssupply chain disruption, quality control issues, recalls or other decreased availability of parts and equipment could adversely affect us.

We are involved in litigation, including various claims, disputesour ability to meet our commitments to customers by making it cost prohibitive to do so, thus adversely impacting our operations and regulatory proceedings that ariserevenues and/or our operating costs. Delays in the ordinary coursedelivery of critical drilling equipment could cause delays in the expected timing of rig reactivation, enhancement or upgrade projects, unscheduled operational downtime, our drilling rigs to be unavailable within the commencement window established by the operator in the contract and subject us to potential termination of the contract for such late delivery of the drilling rig.

Our operating and maintenance costs will not necessarily fluctuate in proportion to changes in our operating revenues.

Our operating and maintenance costs will not necessarily be proportional to changes in our operating revenues. Operating costs are affected by many factors, including inflation, while maintenance costs depend on, among other factors, market conditions for drilling services as well as unplanned downtime events or idle periods between contracts. Costs for operating a rig are therefore generally not correlated to the day rate being earned. As our rigs are mobilized from one geographic location to another, the labor and other operating and maintenance costs can vary significantly. Equipment maintenance costs fluctuate depending upon the age and condition of the equipment, and these costs could increase for short or extended periods as a result of new regulatory or customer requirements. Any of the foregoing could impact our liquidity or may cause us to miss our financial guidance for a given period, which could adversely impact the market price for our Common Shares. In addition, certain of our drilling contracts are partially payable in local currency. The amounts, if any, of local currency received under these drilling contracts may exceed our local currency needs to pay local operating and maintenance costs, leading to an accumulation of excess local currency balances, which, in certain instances, may be subject to either restrictions or other difficulties in converting to U.S. dollars, our functional currency, or to other currencies of the locations where we operate. Excess amounts of local currency may also expose us to the risk of currency exchange losses.

Our ability to pay our operating and capital expenses and make payments due on our debt depends on many factors beyond our control.

Our ability to pay our operating and capital expenses and make payments due on our debt depends on our future performance, which will be affected by financial, business, economic, legislative and other factors, many of which are uninsuredbeyond our control. Our business may not generate sufficient cash flow from operations in the future, which could result in our being unable to fund liquidity needs or repay indebtedness. A range of economic, business and relateindustry factors will affect our financial performance, and many of these factors, such as the condition of our industry, the global economy and initiatives of our competitors, are beyond our control. If we do not generate enough cash flow from operations to intellectual property, commercial, operational, employment, regulatorysatisfy our debt obligations, we may have to undertake alternative financing plans, such as selling assets; reducing or delaying capital investments; seeking to raise additional capital; or restructuring or refinancing all or a portion of our indebtedness at or before maturity.

27


We cannot be assured that we will be able to accomplish any of these alternatives on terms acceptable to us or at all. In addition, the terms of existing or future debt agreements may restrict us from adopting any of these alternatives. The failure to generate sufficient cash flow or to achieve any of these alternatives could materially adversely affect our ability to fund liquidity needs or pay amounts due under our debt.

The agreements governing our debt, including the Indenture and the Credit Agreement, contain various covenants that impose restrictions on us and certain of our subsidiaries that may affect our ability to operate our business and to make payments on our debt.

The Indenture, the Credit Agreement and the related agreements governing our indebtedness contain covenants that, among other things, limit our ability and the ability of certain of our subsidiaries to:
incur additional debt and issue preferred stock;
incur or create liens;
redeem and/or prepay certain debt;
pay dividends on our shares or repurchase shares;
make certain investments;
engage in specified sales of assets;
enter into transactions with affiliates; and
engage in consolidation, mergers and acquisitions.

In addition, the Credit Agreement contains financial covenants requiring us to maintain (i) a minimum book value of equity to total assets ratio, (ii) a minimum interest coverage ratio and (iii) a minimum amount of liquidity. Any future indebtedness may also require us to comply with similar or other activities.covenants. These restrictions on our ability to operate our business could seriously harm our business by, among other things, limiting our ability to take advantage of financings, mergers, acquisitions and other business opportunities.

Various risks, uncertainties and events beyond our control could affect our ability to comply with these covenants. Failure to comply with any of the covenants in our existing or future financing agreements could result in a default under those agreements and under other agreements containing cross-default provisions. A default would permit lenders to accelerate the maturity for the debt under these agreements and to foreclose upon any collateral securing the debt. Under these circumstances, we might not have sufficient funds or other resources to satisfy all of our obligations. In addition, the limitations imposed by financing agreements on our ability to incur additional debt and to take other actions might significantly impair our ability to obtain other financing. This could have serious consequences to our financial condition and results of operations and could cause us to become bankrupt or insolvent.

We may experience risks associated with future mergers, acquisitions or dispositions of businesses or assets or other strategic transactions.

We may pursue mergers, acquisitions or dispositions of businesses or assets or other strategic transactions that we believe will strengthen, streamline or expand our business. Each such transaction would be dependent upon several factors, including identifying suitable companies, businesses or assets that align with our business strategies, reaching agreement with the potential counterparties on acceptable terms, the receipt of any applicable regulatory and other approvals, and other conditions. These transactions involve various risks, including among others, (1) difficulties related to integrating or managing applicable parts of an acquired business or joint venture and unanticipated changes in customer and other third-party relationships subsequent to closing, (2) diversion of management's attention from day-to-day operations, (3) applicable antitrust laws and other regulations that may limit our ability to acquire targets or require us to divest an acquired business or assets, (4) failure to realize anticipated benefits, such as cost savings, revenue enhancements or strengthening or broadening our business, (5)
28


potentially substantial transaction costs associated with acquisitions, joint ventures or investments if we or a transaction counterparty seeks to exit or terminate an interest in the joint venture or investment, and (6) potential accounting impairment or actual diminution or loss of value of our investment if future market, business or other conditions ultimately differ from our assumptions at the time such transaction is consummated.

Our actual financial results after emergence from bankruptcy may not be comparable to our projections filed with the Bankruptcy Court in the course of the Chapter 11 Cases.

In connection with the disclosure statement we filed with the Bankruptcy Court and the hearing to consider confirmation of the plan of reorganization, we prepared projected financial information to demonstrate to the Bankruptcy Court the feasibility of the plan of reorganization and our ability to continue operations upon our emergence from the Chapter 11 Cases. Those projections were prepared solely for the purpose of the Chapter 11 Cases and have not been and will not be updated and should not be relied upon by investors. At the time they were prepared, the projections reflected numerous assumptions concerning our anticipated future performance with respect to then prevailing and anticipated market and economic conditions that were and remain beyond our control and that may not materialize. We have not updated the projections prepared solely for the purpose of our Chapter 11 Cases or the assumptions on which they were based after our emergence. Projections are inherently subject to substantial and numerous uncertainties and to a wide variety of significant business, economic and competitive risks, and the assumptions underlying the projections or valuation estimates may prove to be wrong in material respects. Actual results may vary significantly from those contemplated by the projections. As a result, investors should not rely on these projections.

The exercise of all or any number of outstanding warrants or the issuance or settlement of stock-based awards may dilute the holders of our Common Shares.

On the Effective Date, we issued 75.0 million Common Shares and 5.6 million warrants to purchase 5.6 million Common Shares at an exercise price of $131.88 per share, exercisable for a seven-year period commencing on the Effective Date. Additionally, on May 3, 2021, our board of directors approved and ratified the Valaris Limited 2021 Management Incentive Plan (the “MIP”) and reserved 9.0 million of our Common Shares for issuance under the MIP primarily for employees and directors. The grant and settlement of equity awards in the future, any exercise of the warrants into Common Shares and any sale of Common Shares underlying outstanding warrants will have a dilutive effect to the holdings of our existing shareholders and could have a material adverse effect on the market for our Common Shares, including the price that an investor could obtain for their Common Shares.

Regulatory, Legal and Tax Risks

Failure to comply with anti-corruption and anti-bribery statutes, such as the U.S. Foreign Corrupt Practices Act and the U.K. Bribery Act 2010, could result in fines, criminal penalties, drilling contract terminations and materially adversely affect our financial position, operating results or cash flows.

We operate in a number of countries throughout the world, including countries known to have a reputation for corruption and are subject to the U.S. Foreign Corrupt Practices Act of 1977 (“FCPA”), the U.S. Treasury Department'sDepartment’s Office of Foreign Assets Control ("OFAC"(“OFAC”) regulations, the U.K. Bribery Act ("UKBA"(“UKBA”), other U.S. laws and regulations governing our international operations and similar laws in other countries.

During 2010, Pride and its subsidiaries resolved with the U.S. Department of Justice (“DOJ”) and the SEC their previously disclosed investigations into potential violations of the FCPA. However, Pride received preliminary inquiries from governmental authorities of certain of the countries referenced in its settlements with the DOJ and SEC. We could face additional fines, sanctions and other penalties from authorities in these and other relevant jurisdictions, including prohibition of our participating in or curtailment of business operations in those jurisdictions and the seizure of our rigs or other assets. At this stage of such inquiries, we are unable to determine what, if any, legal liability may result. Our customers in those jurisdictions could seek to impose penalties or take other actions adverse to our interests. We could also face other third-party claims by directors, officers, employees, affiliates, advisors, attorneys, agents, stockholders, debt holders or other stakeholders. In addition, disclosure of the subject matter of the investigations and settlements could adversely affect our reputation and our ability to obtain new business or retain existing business from our current clients and potential clients, to attract and retain employees and to access the capital markets.

In 2015, we became aware of an internal audit report by Petrobras alleging irregularities in relation to a drilling services agreement Pride entered into for ENSCO DS-5. On January 4, 2016, we received a notice from Petrobras declaring the DS-5 drilling services contract between Petrobras and Ensco void effective immediately. Petrobras’ notice alleges that our former marketing consultant both received and procured improper payments from Samsung Heavy Industries for employees of Petrobras and that Pride had knowledge of this activity and assisted in the procurement of and/or facilitated these improper payments. Our Audit Committee appointed independent counsel to lead an investigation into the alleged irregularities. We cannot predict whether any governmental authority will open an investigation into Pride's involvement in this matter, or if a proceeding were opened, the scope or ultimate outcome


of any such investigation. See "Item 3. Legal Proceedings - Brazil Internal Investigation" and "Item 3. Legal Proceedings - DSA Dispute" for further information on the investigation.


Any violation of the FCPA, OFAC regulations, the UKBA or other applicable anti-corruption laws by us, our partners, agents and our and their respective affiliated entities or their respective officers, directors, employees and agents could in some cases provide a customer with termination rights and other remedies under a contractthe terms of their contracts(s) with us and also result in substantial fines, sanctions, civil and/or criminal penalties and curtailment of operations in certain jurisdictions and could materially adversely affect our financial condition, operating results or cash flows or the availability of funds under our revolving credit facility.flows. Further, we may incur significant costs and consume significant internal resources in our efforts to detect, investigate and resolve actual or alleged violations.

Increasing regulatory complexity could adversely impact the costs associated with our offshore drilling operations.operations and reduce demand for our services.


Increases inThe offshore contract drilling industry is dependent on demand for services from the oil and natural gas industry. Accordingly, we will be directly affected by the approval and adoption of laws and regulations limiting or curtailing exploration and development drilling for oil and natural gas for economic, environmental, safety and other policy reasons. Furthermore, we may be required to make significant capital expenditures or incur substantial additional costs to comply with new governmental laws and regulations. It is also possible that legislative and regulatory requirements, particularly in the U.S. Gulf of Mexico,activity could significantly increasematerially adversely affect our costs.financial position, operating results or cash flows by limiting drilling opportunities. In recent years, we have seen several significant regulatory changes that have affected the way we operate in the U.S. Gulf of Mexico. SeeItem 1. Business – Governmental Regulations and Environmental Matters.”

Hurricanes Katrina and Rita in 2005 and Hurricanes Gustav and Ike in 2008 caused damage to a number of rigs in the Gulf of Mexico. Rigs that were moved off location by the storms damaged platforms, pipelines, wellheads and other drilling rigs. As a result of jackup rig fitness requirements during hurricane seasons issued by BSEE and its predecessor agency, jackup rigs in the U.S. Gulf of Mexico are required to operate with a higher air gap (the space between the water level and the bottom of the rig's hull) during hurricane season, effectively reducing the water depth in which they can operate. The guidelines also provide for enhanced information and data requirements from oil and gas companies operating in the U.S. Gulf of Mexico.

Following the 2010 Macondo well incident in the U.S. Gulf of Mexico, the U.S. Department of the Interior issued Notices to Lessees (“NTLs"), implementing new requirements and/or guidelines that are applicable to drilling operations in the U.S. Gulf of Mexico. Current or future NTLs or other rules, directives and regulations may further impact our customers' ability to obtain permits and commence or continue deep or shallow water operations in the U.S. Gulf of Mexico. In 2016, BSEE promulgated the 2016 Well Control Rule imposing new requirements for well-control and blowout prevention equipment that could increase our costs and cause delays in our operations due to unavailability of associated equipment. The 2016 Well Control Rule is currently under review by BSEE pursuant to EO 13783 (“Promoting Energy Independence and Economic Growth”) and Section 7 of EO 13795 (“Implementing an America-First Offshore Energy Strategy”), to determine if the rule should be revised to encourage energy exploration and production on the Outer Continental Shelf, while still providing for safe and environmentally responsible exploration and production activities.

Also, as a result of the Macondo well incident, BSEE and its predecessor agency promulgated regulations regarding SEMS. Although only operators are currently required to have a SEMS, the SEMS regulations require written agreements between operators and contractors regarding the contractors’ support of the operators' safety and environmental policies at the worksite, including requirements for personnel training and written safe work practices. In addition, BSEE has in the past stated that future rulemaking may require offshore drilling contractors to implement their own SEMS programs. The current SEMS regulations and the possibility of additional SEMS rules for contractors could expose us to increased costs.

In 2012, BSEE issued an IPD for use by BSEE inspectors in INCs to contractors operating under BSEE jurisdiction on the Outer Continental Shelf of the U.S. Gulf of Mexico. The stated purpose of the policy was to provide for consistency in application of BSEE enforcement authority by establishing guidelines for issuance of INCs to contractors in addition to operators. The policy indicated that BSEE’s enforcement actions would continue to focus primarily on lessees and operators, but that “in appropriate circumstances” BSEE also would issue INCs to contractors for “serious violations” of BSEE regulations. Following federal court decisions successfully challenging the scope of BSEE’s jurisdiction over offshore contractors, this IPD has been removed from the list of IPDs on the BSEE website. If this judicial precedent stands, it may reduce regulatory and civil litigation liability exposures.



Since 2014, the United States Coast Guard has proposed new regulations that would impose GPS equipment and positioning requirements for mobile offshore drilling units and jackup rigs operating in the U.S. Gulf of Mexico and issued notices regarding the development of guidelines for cybersecurity measures used in the marine and offshore energy sectors for all vessels and facilities that are subject to the MTSA, including our rigs. In 2016, BSEE adopted the 2016 Well Control Rule, which will be implemented in phases over the next several years. This new rule includes more stringent design requirements for well-control equipment used in offshore drilling operations. This rule is currently under review by BSEE and potentially could become less stringent as a result of such review. We are continuing to evaluate the cost and effect that these new rules will have on our operations. However, based on our current assessment of the rules, we do not expect to incur significant costs to comply with the rule. Implementation of further guidelines and regulations may subject us to increased costs and limit the operational capabilities of our rigs.


Any new or additional regulatory, legislative, permitting or certification requirements in the U.S., and other areas in which we operate, including laws and regulations that have or may impose increased financial responsibility, oil spill abatement contingency plan capability requirements, or additional operational requirements and certifications, could materially adversely affect our financial position, operating results or cash flows.


We anticipate that government regulation in other countries where we operate may follow the U.S. in regard to enhanced safety and environmental regulation, which could also result in governments imposing sanctions on contractors when operators fail to comply with regulations that impact drilling operations. Even if not a requirement in these countries, most international operating companies, and many others, are voluntarily complying with some or all of the U.S. inspections and safety and environmental guidelines when operating outside the U.S. Such additional governmental regulation and voluntary compliance by operators could increase the cost of our operations and expose us to greater liability.

Laws and governmental regulations may add to costs, limit our drilling activity or reduce demand for our drilling services.

Our operations are affected by political developments and by laws and regulations that relate directly to the oil and gas industry, including initiatives to limit greenhouse gas emissions. The offshore contract drilling industry is dependent on demand for services from the oil and gas industry. Accordingly, we will be directly affected by the approval and adoption of laws and regulations limiting or curtailing exploration and development drilling for oil and natural gas for economic, environmental, safety and other policy reasons. We may be exposed to risks related to new laws or regulations pertaining to climate change, carbon emissions or energy use that could reduce the use of oil or natural gas, thus reducing demand for hydrocarbon-based fuel and our drilling services. Governments also may pass laws or regulations encouraging or mandating the use of alternative energy sources, such as wind power and solar energy, which may reduce demand for oil and natural gas and our drilling services. Furthermore, we may be required to make significant capital expenditures or incur substantial additional costs to comply with new governmental laws and regulations. It is also possible that legislative and regulatory activity could adversely affect our operations by limiting drilling opportunities or significantly increasing our operating costs.

Geopolitical events, terrorist attacks, piracy and military action could affect the markets for our services and have a material adverse effect on our business and cost and availability of insurance.

Geopolitical events have resulted in military actions, terrorist, pirate and other armed attacks, civil unrest, political demonstrations, mass strikes and government responses. Military action by the United States or other nations could escalate, and acts of terrorism, piracy, kidnapping, extortion, acts of war, violence, civil war or general disorder may initiate or continue. Such acts could be directed against companies such as ours. Such developments have caused instability in the world’s financial and insurance markets in the past. In addition, these developments could lead to increased volatility in prices for oil and natural gas and could affect the markets for our services. Insurance premiums could increase and coverage for these kinds of events may be unavailable in the future. Any or all of these effects could have a material adverse effect on our financial position, operating results or cash flows.



Rig construction, upgrade and enhancement projects are subject to risks, including delays and cost overruns, which could have a material adverse effect on our financial position, operating results or cash flows.

We currently have two ultra-deepwater drillships and one jackup rig under construction. In the future, we may construct additional rigs and continue to upgrade the capability and extend the service lives of our existing rigs. As a result of current market conditions, we may seek to delay delivery of our rigs under construction. We agreed with the shipyard constructing the ENSCO 123 to delay the delivery of the rig until the first quarter of 2019 and, prior to the closing of the Merger, Atwood agreed to delay the delivery of two ultra deepwater drillships into 2019 and 2020. During periods of heightened rig construction projects, shipyards and third-party equipment vendors may be under significant resource constraints to meet delivery obligations. Such constraints may lead to substantial delivery and commissioning delays, equipment failures and/or quality deficiencies. Furthermore, new drilling rigs may face start-up or other operational complications following completion of construction, upgrades or maintenance. Other unexpected difficulties, including equipment failures, design or engineering problems, could result in significant downtime at reduced or zero day rates or the cancellation or termination of drilling contracts.

Rig construction, upgrade, life extension and repair projects are subject to the risks of delay or cost overruns inherent in any large construction project, including the following:

failure of third-party equipment to meet quality and/or performance standards, 

delays in equipment deliveries or shipyard construction, 

shortages of materials or skilled labor, 

damage to shipyard facilities or construction work in progress, including damage resulting from fire, explosion, flooding, severe weather, terrorism, war or other armed hostilities, 

unforeseen design or engineering problems, including those relating to the commissioning of newly designed equipment, 

unanticipated actual or purported change orders, 

strikes, labor disputes or work stoppages, 

financial or operating difficulties of equipment vendors or the shipyard while constructing, enhancing, upgrading, improving or repairing a rig or rigs, 

unanticipated cost increases, 

foreign currency exchange rate fluctuations impacting overall cost, 

inability to obtain the requisite permits or approvals, 

client acceptance delays,

disputes with shipyards and suppliers,

latent damages or deterioration to hull, equipment and machinery in excess of engineering estimates and assumptions,

claims of force majeure events, and 

additional risks inherent to shipyard projects in a non-U.S. location.



With respect to our rigs under construction, if we were to secure contracts for such rigs, we would be subject to the risk of delays and other hazards impacting the viability of such contracts, which could have a material adverse effect on our financial position, operating results or cash flows.

Failure to recruit and retain skilled personnel could adversely affect our operations and financial results.

We require skilled personnel to operate our drilling rigs and to provide technical services and support for our business. Historically, competition for the labor required for drilling operations and construction projects was intense as the number of rigs activated, added to worldwide fleets or under construction increased, leading to shortages of qualified personnel in the industry. During such periods of intensified competition, it is more difficult and costly to recruit and retain qualified employees, especially in foreign countries that require a certain percentage of national employees. If competition for labor were to intensify in the future, we could experience an increase in operating expenses, with a resulting reduction in net income, and our ability to fully staff and operate our rigs could be negatively affected.

We may be required to maintain or increase existing levels of compensation to retain our skilled workforce, especially if our competitors raise their wage rates. We also are subject to potential legislative or regulatory action that may impact working conditions, paid time off or other conditions of employment. If such labor trends continue, they could further increase our costs or limit our ability to fully staff and operate our rigs.

Unionization efforts and labor regulations in certain countries in which we operate could materially increase our costs or limit our flexibility.

Outside of the U.S., we are often subject to collective bargaining agreements that require periodic salary negotiations, which usually result in higher personnel expenses and other benefits. Efforts have been made from time to time to unionize other portions of our workforce. In addition, we have been subjected to strikes or work stoppages and other labor disruptions in certain countries. Additional unionization efforts, new collective bargaining agreements or work stoppages could materially increase our costs, reduce our revenues or limit our flexibility.

Certain legal obligations require us to contribute certain amounts to retirement funds or other benefit plans and restrict our ability to dismiss employees. Future regulations or court interpretations established in the countries in which we conduct our operations could increase our costs and materially adversely affect our business, financial position, operating results or cash flows.


Compliance with or breach of environmental laws can be costly and could limit our operations.


Our operations are subject to laws and regulations controlling the discharge of materials into the environment, pollution, contamination and hazardous waste disposal or otherwise relating to the protection of the environment. Environmental laws and regulations specifically applicable to our business activities could impose significant liability on us for damages, clean-up costs, fines and penalties in the event of oil spills or similar discharges of pollutants or contaminants into the environment or improper disposal of hazardous waste generated in the course of our operations. To date, such laws and regulations have not had a material adverse effect on our operating results, and we have not experienced an accident that has exposed us to material liability arising out of or relating to discharges of pollutants into the environment. However, the legislative, judicial and regulatory response to a well incident could substantially increase our and our customers'customers’ liabilities. In addition to potential increased liabilities, such legislative, judicial or regulatory action could impose increased financial, insurance or other requirements that may adversely impact the entire offshore drilling industry. SeeItem 1. Business – Governmental Regulations and Environmental Matters” and “Item 3. Legal Proceedings – Environmental Matters.”

The International Convention on Oil Pollution Preparedness, ResponseSustainability initiatives and Cooperation, the International Convention on Civil Liability for Oil Pollution Damage 1992, the U.K. Merchant Shipping Act 1995, Marpol 73/78 (the International Convention for the Prevention of Pollution from Ships), the U.K. Merchant Shipping (Oil Pollution Preparedness, Response and Co-operation Convention) Regulations 1998, as amended, and other related legislation and regulations and the OPA 90, as amended, the Clean Water Act, and other U.S. federal statutes applicable to us and our operations, as well as similar statutes in Texas, Louisiana, other coastal states and other non-U.S. jurisdictions,


address oil spill prevention, reporting and control and have significantly expanded potential liability, fine and penalty exposure across many segments of the oil and gas industry.

Such statutes and related regulations impose a variety of obligations on us related to the prevention of oil spills, disposal of waste and liability for resulting damages. For instance, OPA 90 imposes strict and, with limited exceptions, joint and several liability upon each responsible party for oil removal costs as well as a variety of fines, penalties and damages. Although OPA 90 provides for certain limits of liability, such limits are not applicable where there is any safety violation or where gross negligence is involved. Failure to comply with these statutes and regulations, including OPA 90, may subject us to civil or criminal enforcement action, which may not be covered by contractual indemnification or insurance and could have a material adverse effect on our financial position, operating results or cash flows. Further, remedies under the Clean Water Act and related legislation and OPA 90 do not preclude claims under state regulations or civil claims for damages to third parties under state laws.

Highhigh profile and catastrophic environmental events, includingsuch as the 2010 Macondo well incident, have heightened governmental and environmental concerns about the risks associated withled to increased regulation of offshore oil and natural gas drilling. We are adversely affected by restrictions on drilling in certainthe areas in which we operate, including policies and guidelines regarding the approval of drilling permits, restrictions on development and production activities, and directives and regulations that have and may further impact our operations. From time to time, legislative and regulatory proposals have been introduced that would materially limit or prohibit offshore drilling in certain areas, or that would increase the liabilities or costs associated with offshore drilling. If new laws are enacted, or if government actions are taken that restrict or prohibit offshore drilling in our principal areas of operation or that impose environmental or other requirements that materially increase the liabilities, financial requirements or operating or equipment costs associated with offshore drilling, exploration, development, or production of oil and natural gas, our financial position, operating results or cash flows could be materially adversely affected.

Our debt levels and debt agreement restrictions may limit our liquidity and flexibility in obtaining additional financing and in pursuing other business opportunities.
As of December 31, 2017, we had $4.8 billion in total debt outstanding, representing approximately 35.2% of our total capitalization. Our current indebtedness may have several important effects on our future operations, including:
a substantial portion of our cash flows from operations will be dedicated to the payment of principal and interest,
covenants contained in our debt arrangements require us to meet certain financial tests, which may affect our flexibility in planning for, and reacting to, changes in our business and may limit our ability to dispose of assets or place restrictions on the use of proceeds from such dispositions, withstand current or future economic or industry downturns and compete with others in our industry for strategic opportunities, and30



our ability to obtain additional financing to fund working capital requirements, capital expenditures, acquisitions, dividend payments and general corporate or other cash requirements may be limited.

Our ability to maintain a sufficient level of liquidity to meet our financial obligations will 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. Our future cash flows may be insufficient to meet all of our working capital requirements, debt obligations and contractual commitments, and any insufficiency could negatively impact our business.

To the extent we are unable to repay our debt as it becomes due with cash on hand or from other sources, we will need to refinance our debt, sell assets or repay the debt with the proceeds from equity offerings. Additional indebtedness or equity financing may not be available to us in the future for the refinancing or repayment of existing debt, or if available, such additional debt or equity financing may not be available on a timely basis, or on terms


acceptable to us and within the limitations specified in our then existing debt instruments. In addition, in the event we decide to sell additional assets, we can provide no assurance as to the timing of any asset sales or the proceeds that could be realized by us from any such asset sale.

Our revolving credit facility places restrictions on us and certain of our subsidiaries with respect to incurring additional indebtedness and liens, making dividends and other payments to shareholders, repurchasing our common stock, repurchasing or redeeming certain other indebtedness which matures after the revolving credit facility, entering into mergers and other matters. Our revolving credit facility also requires compliance with covenants to maintain specified financial and guarantee coverage ratios. These restrictions may limit our flexibility in obtaining additional financing and in pursuing various business opportunities.

In addition, our access to credit and capital markets depends on the credit ratings assigned to our credit facility and our notes by independent credit rating agencies. In recent years, we have experienced downgrades in our corporate credit rating and the credit rating of our senior notes. Our access to credit and capital markets may be more limited because we no longer have an investment grade credit rating. Any additional actual or anticipated downgrades in our corporate credit rating or the credit rating of our notes could further limit our ability to access credit and capital markets, or to restructure or refinance our indebtedness. Furthermore, future financings or refinancings may result in higher borrowing costs and require more restrictive terms and covenants, which may further restrict our operations. With our current credit ratings below investment grade, we have no access to the commercial paper market. Limitations on our ability to access credit and capital markets could have a material adverse impact on our financial position, results of operations and liquidity.

We have historically made substantial capital expenditures to maintain our fleet to comply with laws and the applicable regulations and standards of governmental authorities and organizations, or to expand our fleet, and we may be required to make significant capital expenditures to maintain our competitiveness, which could adversely affect our financial condition, operating results or cash flows.

We have historically made substantial capital expenditures to maintain our fleet. These expenditures could increase as a result of changes in:

offshore drilling technology,

the cost of labor and materials,

customer requirements,

fleet size,

the cost of replacement parts for existing drilling rigs,

the geographic location of the drilling rigs,

length of drilling contracts,

governmental regulations and maritime self-regulatory organization and technical standards relating to safety, security or the environment, and

industry standards.



Changes in offshore drilling technology, customer requirements for new or upgraded equipment and competition within our industry may require us to make significant capital expenditures in order to maintain our competitiveness. In addition, changes in governmental regulations, relating to safety or equipment standards, as well as compliance with standards imposed by maritime self-regulatory organizations, may require us to make additional unforeseen capital expenditures. As a result, we may be required to take our rigs out of service for extended periods of time, with corresponding losses of revenues, in order to make such alterations or to add such equipment. In the future, market conditions may not justify these expenditures or enable us to operate our older rigs profitably during the remainder of their economic lives.

Additionally, in order to expand our fleet, we may require additional capital in the future. If we are unable to fund capital with cash flows from operations or sales of non-core assets, we may be required to either incur additional borrowings or raise capital through the sale of debt or equity securities. Our ability to access the capital markets may be limited by our financial condition at the time, by changes in laws and regulations (or interpretation thereof) and by adverse market conditions resulting from, among others, general economic conditions, contingencies and uncertainties that are beyond our control. If we raise funds by issuing equity securities, existing shareholders may experience dilution. Our failure to obtain the funds for necessary future capital expenditures could have a material adverse effect on our business and on our financial position, operating results or cash flows.

Significant part or equipment shortages, supplier capacity constraints, supplier production disruptions, supplier
quality and sourcing issues or price increases could increase our operating costs, decrease our revenues and adversely impact our operations.

Our reliance on third-party suppliers, manufacturers and service providers to secure equipment, parts, components and sub-systems used in our operations exposes us to potential volatility in the quality, prices and availability of such items. Certain high-specification parts and equipment that we use in our operations may be available only from a small number of suppliers, manufacturers or service providers, or in some cases must be sourced through a single supplier, manufacturer or service provider. Recent industry consolidation has reduced the number of available suppliers. A disruption in the deliveries from such third-party suppliers, manufacturers or service providers, capacity constraints, production disruptions, price increases, quality control issues, recalls or other decreased availability of parts and equipment could adversely affect our ability to meet our commitments to customers, thus adversely impacting our operations and revenues and/or our operating costs.

Our long-term contracts are subject to the risk of cost increases, which could adversely impact our profitability.

In general, our costs increase as the demand for contract drilling services and skilled labor increases. While many of our contracts include cost escalation provisions that allow changes to our day rate based on stipulated cost increases or decreases, the timing and amount earned from these day rate adjustments may differ from our actual increase in costs and certain contracts do not allow for such day rate adjustments. During times of reduced demand, reductions in costs may not be immediate as portions of the crew may be required to prepare our rigs for stacking, after which time the crew members are assigned to active rigs or dismissed. Moreover, as our rigs are mobilized from one geographic location to another, the labor and other operating and maintenance costs can vary significantly. In general, labor costs increase primarily due to higher salary levels and inflation. Equipment maintenance expenses fluctuate depending upon the type of activity a drilling rig is performing and the age and condition of the equipment. Contract preparation expenses vary based on the scope and length of contract preparation required.



Our information technology systems are subject to cybersecurity risks and threats.

We depend on technologies, systems and networks to conduct our offshore and onshore operations, to collect payments from customers and to pay vendors and employees.  The risks associated with cyber incidents and attacks to our information technology systems could include disruptions of certain systems on our rigs; other impairments of our ability to conduct our operations; loss of intellectual property, proprietary information or customer and vendor data; disruption of our or our customers' operations; and increased costs to prevent, respond to or mitigate cybersecurity events.  Despite our security measures, our information technology and infrastructure may be vulnerable to attacks by hackers or breached due to employee error, malfeasance or other disruptions. Any such breach could compromise our networks or our customers' and vendors' networks and the information stored there could be accessed, publicly disclosed, lost or stolen. Any such access, disclosure or other loss of information could result in legal claims or proceedings, disrupt our operations and damage our reputation, which could adversely affect our financial position, operating results or cash flows.    

The accounting method for our 2024 Convertible Notes could have a material effect on our reported financial results.
Under U.S. GAAP, we must separately account for the liability and equity components of convertible debt instruments, such as our 3.00% exchangeable senior notes due 2024 (the “2024 Convertible Notes”) in a manner that reflects the issuer’s economic interest cost. The equity component representing the conversion feature is recorded in additional paid-in capital within the shareholders’ equity section of our consolidated balance sheet. The carrying value of the debt component is recorded with a corresponding discount that will result in a significant amount of non-cash interest expense from the accretion of the discounted carrying value up to the principal amount over the term of the 2024 Convertible Notes. The equity component is not remeasured if we continue to meet certain conditions for equity classification under U.S. GAAP, including maintaining the ability to settle the 2024 Convertible Notes entirely in shares. During periods in which we are unable to meet the conditions for equity classification, the equity component or a portion thereof would be remeasured through earnings, which could adversely affect our operating results.

Upon conversion of the 2024 Convertible Notes, holders will receive cash, our Class A ordinary shares or a combination thereof, at our election. Our intent is to settle the principal amount of the 2024 Convertible Notes in cash upon conversion. If the conversion value exceeds the principal amount (i.e., our share price exceeds the exchange price on the date of conversion), we expect to deliver shares equal to our conversion obligation in excess of the principal amount. During each respective reporting period that our average share price exceeds the exchange price, an assumed number of shares required to settle the conversion obligation in excess of the principal amount will be included in the denominator for our computation of diluted earnings per share using the treasury stock method. If we are unable to demonstrate our intent to settle the principal amount in cash, or are otherwise unable to utilize the treasury stock method, our diluted earnings per share would be adversely affected. See Note 5 to our consolidated financial statements included in "Item 8. Financial Statements and Supplementary Data" for additional information on our 2024 Convertible Notes.


The IRS may not agree with the conclusion that we should be treated as a foreign corporation for U.S. federal tax purposes following the Merger.purposes.


Although Ensco plcValaris Limited is incorporated in Bermuda (and thus would generally be considered a “foreign” corporation (or non-U.S. tax resident)), the United Kingdom, the U.S. Internal Revenue Service (“IRS”) mayIRS could assert that we should be treated as a U.S. corporation (and therefore, a U.S. tax resident) for U.S. federal income tax purposes followingpursuant to the Merger pursuant torules under Section 7874 of the Internal Revenue Code. For U.S. federal income tax purposes, a corporation is generally consideredWhile we do not believe we are a U.S. “domestic” corporation (or U.S. tax resident) if it is organized in the United States, and a corporation is generally considered a “foreign” corporation (or non-U.S. tax resident) if it is not a U.S. domestic corporation. Because Ensco plc is an entity incorporated in England and Wales, it would generally be classified as a foreign corporation (or non-U.S. tax resident) under these rules. Section 7874 of the Internal Revenue Code provides an exception under which a foreign incorporated entity may, in certain circumstances, be treated as a U.S. domestic corporation for U.S. federal income tax purposes.



We would be treated as a U.S. domestic corporation (that is, as a U.S. tax resident) for U.S. federal income tax purposes following the Merger pursuant to Section 7874 ofthese rules, the Internal Revenue Code ifrules are complex and the percentage (by vote or value) of our shares considered to be held by former holders of shares of Atwood common stock after the Merger by reason of holding shares of Atwood common stock for purposes of Section 7874 of the Internal Revenue Code (the “Section 7874 Percentage”) was 80% or more.

The Section 7874 Percentage at the time of the Merger was less than 60%. The calculation of the Section 7874 Percentage, however, is complex, is subject to detailed regulations anddetermination is subject to factual uncertainties. As a result, the IRS could assert that the Section 7874 Percentage was greater than 80% and that we therefore are treated for U.S. federal income tax purposes as a U.S. domestic corporation (that is, as a U.S. tax resident) following the Merger. If the IRS successfully challenged our status as a foreign corporation, significant adverse tax consequences would result for us and for certain of our shareholders.

U.S. tax laws and IRS guidance could affect our ability to engage in certain acquisition strategies and certain internal restructurings.

Even if we are treated as a foreign corporation for U.S. federal income tax purposes, Section 7874 of the Internal Revenue Code and U.S. Treasury Regulations promulgated thereunder, including temporary Treasury Regulations, may adversely affect our ability to engage in certain future acquisitions of U.S. businesses in exchange for our equity, which may affect the tax efficiencies that otherwise might be achieved in such potential future transactions.


Governments may pass laws that subject us to additional taxation or may challenge our tax positions, which could adversely affect our financial position, operating results or cash flows.positions.


There is increasing uncertainty with respect to tax laws, regulations and treaties, and the interpretation and enforcement thereof that may affect our business. TheFor example, the Organization for Economic Cooperation and Development (“OECD”) has issued its final reports on Base Erosion, the European Union, and Profit Shifting, which generally focus on situations where profits are earnedcertain other countries (including countries in low-tax jurisdictions, or payments are made between affiliates from jurisdictions with high tax rates to jurisdictions with lower tax rates. Certain countries within which we operate have recently enactedoperate) are committed to enacting substantial changes to theirnumerous long-standing tax lawsprinciples impacting how large multinational enterprises are taxed. In particular, the OECD’s Pillar Two initiative introduces a 15% global minimum tax applied on a country-by-country basis and for which many jurisdictions committed to an effective enactment date starting January 1, 2024, though not all jurisdictions were expected to meet this target deadline. The impact of these potential new rules as well as any other changes in response to the OECD recommendations or otherwisedomestic and theseinternational tax rules and other countries may enact changes to their tax laws or practices in the future (prospectively or retroactively), which mayregulations could have a material adverse effect on our financial position, operating results or cash flows. The recently enacted U.S. federal incomeeffective tax reform legislation, informally known as the Tax Cuts and Jobs Act of 2017, made substantial changes in the taxation of U.S. and multinational corporations, including a significant reduction in the statutory corporate income tax rate, a limitation on the ability of corporations to deduct interest expense, the imposition of tax on low taxed intangible income of foreign subsidiaries, and the imposition of a base erosion anti-abuse tax.rate.


In addition, our tax positions are subject to audit by U.K., U.S. and other foreign tax authorities. Such tax authorities may, and do from time to time, disagree with our interpretations or assessments of the effects of tax laws, treaties or regulations or their applicability to our corporate structure or certain transactions we have undertaken. We currently are subject to tax assessments in various jurisdictions, which we are contesting. Even if we are successful in maintaining our tax positions, we may incur significant expenses in defending our positions and contesting claims asserted by tax authorities. If we are unsuccessful in defending our tax positions, the resulting assessments or rulings could significantly impact our consolidated income taxes in past or future periods.

As required by law, we file periodic tax returns that are subject to review and examination by various revenue agencies within the jurisdictions in which we operate. We are currently subject to tax assessments in various jurisdictions, which we are contesting.

As a result of these uncertainties, as well as changes in the administrative practices and precedents of tax authorities or other matters, (suchsuch as changes in applicable accounting rules)rules, that increase the amounts we have provided for income taxes or deferred tax assets and liabilities in our consolidated financial statements, we cannot provide any assurances as to what our consolidated effective income tax rate will be in future periods. If we are unable to mitigate the negative consequences of any change in law, audit or other matters, this could cause our consolidated income taxes to increase and cause a material adverse effect onmaterially adversely affect our financial position, operating results or cash flows.



31



Our consolidated effective income tax rate may vary substantially from one reporting period to another.over time.


We cannot provide any assurances as to what our future consolidated effective income tax rate will be because of, among other matters, uncertainty regarding the nature and extent of our business activities in any particular jurisdiction in the future and the tax laws of such jurisdictions, as well as potential changes in U.K., U.S. and other foreign tax laws, regulations or treaties or the interpretation or enforcement thereof, changes in the administrative practices and precedents of tax authorities or other matters (such as changes in applicable accounting rules) that increase the amounts we have provided for income taxes or deferred tax assets and liabilities in our consolidated financial statements. In addition, as a result of frequent changes in the taxing jurisdictions in which our drilling rigs are operated and/or owned, changes in the overall level of our income and changes in tax laws, our consolidated effective income tax rate may vary substantially from one reporting period to another. In periods of declining profitability, our income tax expense may not decline proportionately with income. Further, we may continue to incur income tax expense in periods in which we operate at a loss. Income tax rates imposed in the tax jurisdictions in which our subsidiaries conduct operations vary, as does the tax base to which the rates are applied. In some cases, tax rates may be applicable to gross revenues, statutory or negotiated deemed profits or other bases utilized under local tax laws, rather than to net income. In some instances, the movement of drilling rigs among taxing jurisdictions will involve the transfer of ownership of the drilling rigs among our subsidiaries.subsidiaries, which may result in the imposition of transaction taxes, which could be material. If we are unable to mitigate the negative consequences of any change in law, audit, business activity or other matters, this could cause our consolidated effective income tax rate to increase and causematerially adversely affect our financial position, operating results or cash flows.

We are subject to litigation that could have a material adverse effect on us.

We are, from time to time, involved in various litigation matters. These matters may include, among other things, contract disputes, personal injury claims, toxic tort claims, environmental claims or proceedings, employment matters, issues related to employee or representative conduct, governmental claims for taxes or duties, and other litigation that arises in the ordinary course of our business. Although we intend to defend or pursue such matters vigorously, we cannot predict with certainty the outcome or effect of any claim or other litigation matter, and there can be no assurance as to the ultimate outcome of any litigation. Litigation could materially adversely affect our financial position, operating results or cash flows because of potential negative outcomes, legal fees, the allocation of management’s time and attention, and other factors.

We could also face increased climate-related litigation with respect to our operations both in the U.S. and around the world. Governmental and other entities in various states, such as California and New York, have filed lawsuits against coal, oil and natural gas companies. These suits allege damages as a result of climate change, and the plaintiffs are seeking unspecified damages and abatement under various legal theories. Similar lawsuits may be filed in other jurisdictions both in the U.S. and globally. Although we are not currently a party to any such lawsuit, these suits present uncertainty regarding the extent to which companies who are not producing oil or natural gas, but who are engaged to provide services to support production activities, such as offshore drilling companies, face an increased risk of liability stemming from climate-related litigation, which risk would also adversely impact the oil and natural gas industry and impact demand for our services.

We are a Bermuda company and it may be difficult to enforce judgments against us or our directors and executive officers.

We are a Bermuda exempted company. As a result, the rights of holders of our Common Shares are governed by Bermuda law and our memorandum of association and bye-laws. The rights of shareholders under Bermuda law may differ from the rights of shareholders of companies incorporated in other jurisdictions. Some of our directors and officers are not residents of the U.S., and a substantial portion of our assets are located outside the U.S. As a result, it may be difficult for investors to effect service of process on those persons in the U.S. or to enforce in the U.S. judgments obtained in U.S. courts against us or those persons based on the civil liability provisions of the U.S. securities laws. It is doubtful whether courts in Bermuda will enforce judgments obtained in other jurisdictions, including the U.S., against us or our directors or officers under the securities laws of those jurisdictions or entertain actions in Bermuda against us or our directors or officers under the securities laws of other jurisdictions.

Our bye-laws restrict shareholders from bringing legal action against our officers and directors.

Our bye-laws contain a broad waiver by our shareholders of any claim or right of action, both individually and on our behalf, against any of our officers or directors. The waiver applies to any action taken by an officer or director, or the failure of an officer or director to take any action, in the performance of his or her duties, except with respect to any matter involving any fraud or dishonesty on the part of the officer or director. This waiver limits the right of shareholders to assert claims against our officers and directors unless the act or failure to act involves fraud or dishonesty.

Provisions in our bye-laws could delay or prevent a change in control of our company, which could materially adversely affect the price of our Common Shares.

Some of the provisions in our bye-laws could delay or prevent a change in control of our company that a shareholder may consider favorable, which could materially adversely affect the price of our Common Shares. Certain provisions of our bye-laws could make it more difficult for a third party to acquire control of our company, even if the change of control would be beneficial to our shareholders. These provisions include:
authority of our board of directors to determine its size;
the ability of our board of directors to issue preferred shares without shareholder approval;
limitations on the removal of directors; and
limitations on the ability of our shareholders to act by written consent in lieu of a meeting.
In addition, our bye-laws establish advance notice provisions for shareholder proposals and nominations for elections to the board of directors to be acted upon at meetings of shareholders.

Legislation enacted in Bermuda as to Economic Substance may affect our operations.

The Economic Substance Act came into effect in Bermuda on January 1, 2019. This law requires a registered entity other than an entity which is resident for tax purposes in certain jurisdictions outside Bermuda that carries as a business any one or more of the “relevant activities” must comply with economic substance requirements. The Economic Substance Act may require in-scope Bermuda entities, which are engaged in such “relevant activities,” to be directed and managed in Bermuda, have an adequate level of qualified employees in Bermuda, incur an adequate level of annual expenditure in Bermuda, maintain physical offices and premises in Bermuda or perform core income-generating activities in Bermuda. The list of “relevant activities” includes carrying on any one or more of: banking, insurance, fund management, financing and leasing, headquarters, shipping, distribution and service center, intellectual property and holding entities. The Economic Substance Act could affect the manner in which we operate our business. To the extent we or any of our Bermuda subsidiaries carry on any relevant activities for the purposes of the Economic Substance Act, we or such subsidiaries will be required to comply with such economic substance requirements. Our compliance with the Economic Substance Act
33


may result in additional costs that could have a material adverse effect on our financial position or results of operations.

Our business could be affected as a result of activist investors.

Publicly traded companies have increasingly become subject to campaigns by activist investors advocating corporate actions such as actions related to sustainability matters, financial restructuring, increased borrowing, dividends, share repurchases or sales of assets or even the entire company. Responding to proxy contests and other actions by such activist investors or others could be costly and time-consuming, disrupt our operations and divert the attention of our board of directors and senior management from the pursuit of our business strategies, which could materially adversely affect our financial position, operating results or cash flows. Additionally, perceived uncertainties as to our future direction as a result of investor activism or changes to the composition of the board of directors may lead to the perception of a change in the direction of our business, instability or lack of continuity, which may be exploited by our competitors, cause concern to our current or potential customers, and make it more difficult to attract and retain qualified personnel. If customers choose to delay, defer or reduce transactions with us or transact with our competitors instead of us because of any such issues, then our financial position, operating results or cash flows could be materially adversely affected. In addition, the trading price of our shares could experience periods of increased volatility as a result of investor activism.

Risks Related to Our International Operations

Our non-U.S. operations involve additional risks not typically associated with U.S. operations.

Revenues from non-U.S. operations were 80%, 78%, 87% and 81% of our total consolidated revenues for the years ended December 31, 2023 and 2022, and eight months ended December 31, 2021 (Successor) and for four months ended April 30, 2021 (Predecessor), respectively. Our non-U.S. operations and shipyard rig construction and enhancement projects are subject to political, economic and other uncertainties, including:

terrorist acts, war and civil disturbances,
expropriation, nationalization, deprivation or confiscation of our equipment or our customer’s property,

We historically have maintained insurance coverage and obtained contractual indemnities that protect us from some, but not all, of the risks associated with our non-U.S. operations such as nationalization, deprivation, expropriation, confiscation, political and war risks. However, there can be no assurance that any particular type of contractual or insurance protection will be available in the future or that we will be able to purchase our desired level of insurance coverage at commercially feasible rates. Moreover, we may initiate a self-insurance program through one or more captive insurance subsidiaries. In circumstances where we have insurance protection for some or all of the risks associated with non-U.S. operations, such insurance may be subject to cancellation on short notice, and it is unlikely that we would be able to remove our rig or rigs from the affected area within the notice period. Accordingly, a significant event for which we are uninsured, underinsured or self-insured, or for which we have not received an enforceable contractual indemnity from a customer, could materially adversely affect our financial position, operating results or cash flows.


TransfersWe are subject to various tax laws and regulations in substantially all countries in which we operate or have a legal presence. Actions by tax authorities that impact our business structures and operating strategies, such as changes to tax treaties, laws and regulations, or the interpretation or repeal of any of the foregoing or changes in the administrative practices and precedents of tax authorities, adverse rulings in connection with audits or otherwise, or other challenges may have a material impact on our tax expense.

Our non-U.S. operations are also subject to various laws and regulations in the countries in which we operate, including laws and regulations relating to the operation of drilling rigs and the requirements for equipment. We may be required to make significant capital expenditures to operate in such countries, which may not be reimbursed by our customers. Governments in some countries are active in regulating and controlling the ownership of oil, natural gas and mineral concessions and companies holding such concessions, the exploration of oil and natural gas and other aspects of the oil and natural gas industry in their countries. In some areas of the world, government activity has materially adversely affected the amount of exploration and development work performed by major international oil companies and may continue to do so. Moreover, certain countries accord preferential treatment to local contractors or joint ventures or impose specific quotas for local goods and services, which can increase our operational costs and place us at a competitive disadvantage. There can be no assurance that such laws and regulations or activities will not materially adversely affect our financial position, operating results or cash flows.

The shipment of goods, services and technology across international borders subjects us to extensive trade laws and regulations. Our import activities are governed by specific customs laws and regulations in each of the countries where we operate. Moreover, many countries, including the U.S., control the export and re-export of certain goods, services and technology and impose related export recordkeeping and reporting obligations. Governments also may impose express or de facto economic sanctions against certain countries, persons and other entities that may restrict or prohibit transactions involving such countries, persons and entities.

35


The laws and regulations concerning import activity, export recordkeeping and reporting, export control and economic sanctions are complex and frequently changing. These laws and regulations may be enacted, amended, enforced or interpreted in a manner materially impacting our operations. Shipments can be delayed and denied export or entry for a variety of reasons, some of which are outside our control and some of which may result from failure to comply with existing legal and regulatory regimes. Shipping delays or denials could cause unscheduled operational downtime, reduced day rates during such downtime and contract cancellations. Any failure to comply with applicable legal and regulatory trading obligations also could result in criminal and civil penalties and sanctions, such as fines, imprisonment, exclusion from government contracts, seizure of shipments and loss of import and export privileges.

Our partners, agents and our and their respective affiliated entities or respective officers, directors, employees and agents may take actions in violation of our Class A ordinary sharespolicies and procedures designed to promote compliance with the laws of the jurisdictions in which we operate. Any such violation could materially adversely affect our financial position, operating results or cash flows.

Sustainability Risks

Regulation of GHG and climate change could have a negative impact on our business.

Governments around the world are increasingly focused on enacting laws and regulations regarding climate change and regulation of GHG that may be subject to stamp dutyimpact our operations, profitability and competitiveness. Restrictions on GHG emissions or stamp duty reserve tax (“SDRT”)other related legislative or regulatory enactments could have an indirect effect in those industries that use significant amounts of petroleum products, which could potentially result in a reduction in demand for petroleum products and, consequently, our offshore contract drilling services. Lawmakers and regulators in the U.K., which wouldU.S. and certain jurisdictions where we operate have proposed or enacted regulations requiring reporting of GHG emissions and the restriction thereof, including increased fuel efficiency standards, carbon taxes or cap and trade systems, restrictive permitting, and incentives for renewable energy. For example, the SEC has proposed a mandatory climate change reporting framework that, if implemented, is likely to materially increase the costamount of dealingtime, monitoring, diligence, and reporting costs related to these matters. In 2023, the current U.S. administration continued initiatives targeting the reduction of methane emissions, including a focus on the energy sector. In December 2023, the EPA adopted a final rule enacting a series of actions targeting methane and other emission reductions in our Class A ordinary shares.

Stamp duty and/or SDRT are imposednatural gas and oil operations. Global efforts have been made and continue to be made in the U.K. on certain transfersinternational community toward the adoption of chargeable securities (which include shares in companies incorporated in the U.K.) at a rateinternational treaties or protocols that would address global climate change issues and impose reductions of 0.5% of the consideration paid for the transfer. Certain transfers of shares to depositary receipt facilities or clearance systems providers are charged at a higher rate of 1.5%.

Pursuant to arrangements that we entered into with the Depository Trust Company (“DTC”), our Class A ordinary shares are eligible to be held in book entry form through the facilities of DTC. Transfers of shares held in book entry form through DTC will not attract a charge to stamp duty or SDRT in the U.K. A transfer of the shares from within the DTC system out of DTC and any subsequent transfers that occur entirely outside the DTC system will attract a charge to stamp duty at a rate of 0.5% of any consideration, which is payable by the transferee of the shares. Any such duty must be paid (and the relevant transfer document stamped by Her Majesty's Revenue & Customs (“HMRC”)) before the transfer can be registered in the share register of Ensco plc. If a shareholder decides to redeposit shares into DTC, the redeposit will attract SDRT at a rate of 1.5% of the value of the shares.

We have put in place arrangements with our transfer agent to require that shares held in certificated form cannot be transferred into the DTC system until the transferor of the shares has first delivered the shares to a depository specified by us so that SDRT may be collectedhydrocarbon-based fuels, including plans developed in connection with the initial deliveryParis climate conference in December 2015, the Katowice climate conference in December 2018 and the UN Climate Change Conferences since 2021. In January 2023, the EU enacted the Corporate Sustainability Reporting Directive, which will require sustainability reporting across a broad range of sustainability topics for both EU and non-EU companies.

Laws or regulations incentivizing or mandating the use of alternative energy sources such as wind power and solar energy have also been enacted in certain jurisdictions. Additionally, numerous large cities globally and several countries have adopted programs to mandate or incentivize the conversion from internal combustion engine powered vehicles to electric-powered vehicles and placed restrictions on non-public transportation. Such policies or other laws, regulations, treaties and international agreements related to GHG and climate change may negatively impact the price of oil relative to other energy sources, reduce demand for hydrocarbons, limit drilling in the offshore oil and natural gas industry, or otherwise unfavorably impact our business, our suppliers and our customers, and result in increased compliance costs and additional operating restrictions, all of which could materially adversely affect our financial position, operating results or cash flows.

36


In addition to potential impacts on our business resulting from climate-change legislation or regulations, our business also could be materially adversely affected by climate-change related physical changes, such as changing weather patterns. An increase in severe weather patterns could result in damage to or loss of our drilling rigs, impact our ability to conduct our operations and/or result in a disruption of our customers’ operations. Finally, increasing attention to the depository. Anyrisks of climate change has resulted in an increased possibility of lawsuits or investigations brought by public and private entities against oil and natural gas companies in connection with their GHG emissions. Should we be targeted by any such shares willlitigation or investigations, we may incur liability, which could be evidenced byimposed without regard to the causation of or contribution to the asserted damage, or to other mitigating factors. The ultimate impact of GHG emissions-related agreements, legislation and measures on our financial performance is highly uncertain because we are unable to predict, in a receipt issued bymultitude of jurisdictions, the depository. Before the transfer can be registered in our share register, the transferor will also be required to provide the transfer agent sufficient funds to settle the resultant liabilityoutcome of political decision-making processes.

Consumer preferences for SDRT, which will be charged at a rate of 1.5%alternative fuels and electric-powered vehicles, as part of the valueglobal energy transition, may lead to reduced demand for our services.

The increasing penetration of renewable energy into the energy supply mix, the increased production of electric-powered vehicles and improvements in energy storage, as well as changes in consumer preferences, including increased consumer demand for alternative fuels, energy sources and electric-powered vehicles may materially adversely affect the demand for oil and natural gas and our drilling services. This evolving transition of the shares.

Following decisionsglobal energy system from fossil-based systems of energy production and consumption to more renewable energy sources, commonly referred to as the European Court of Justice and the U.K. First-tier Tax Tribunal, HMRC has announced that it will not seek to apply a charge to stamp duty or SDRT on the issuance of shares (or, where it is integral to the raising of new capital, the transfer of new shares) into a depositary receipt facility or clearance system provider, such as DTC. However, it is possible that the U.K. government may change or enact laws applicable to stamp duty or SDRT in response to this decision, which could have a material effect on the cost of trading in our shares.



If our Class A ordinary shares are not eligible for continued deposit and clearing within the facilities of DTC, then transactions in our securities may be disrupted.

The facilities of DTC are widely-used for rapid electronic transfers of securities between participants within the DTC system, which include numerous major international financial institutions and brokerage firms. Currently, all trades of our Class A ordinary shares on the NYSE are cleared and settled on the facilities of DTC. Our Class A ordinary shares are, at present, eligible for deposit and clearing within the DTC system, pursuant to arrangements with DTC whereby DTC accepted our Class A ordinary shares for deposit, clearing and settlement services, and we agreed to indemnify DTC for any stamp duty and/or SDRT that may be assessed upon it as a result of its service as a clearance system provider for our Class A ordinary shares. However, DTC retains sole discretion to cease to act as a clearance system provider for our Class A ordinary shares at any time.

If DTC determines at any time that our shares are no longer eligible for deposit, clearing and settlement services within its facilities, our shares may become ineligible for continued listing on a U.S. securities exchange, and trading in such shares would be disrupted. In this event, DTC has agreed it will provide us advance notice and assist us, to the extent possible, with efforts to mitigate adverse consequences. While we would pursue alternative arrangements to preserve our listing and maintain trading, any such disruptionenergy transition, could have a material adverse effectimpact on our results of operations, financial position and cash flows. As a result of changes in consumer preferences and uncertainty regarding the trading pricepace of the energy transition and expected impacts on oil and natural gas demand, some of our Class A ordinary shares.customers are transitioning their businesses to renewable energy projects and away from oil and natural gas exploration and production, which may result in reduced capital spending by such customers on oil and natural gas projects and in turn reduced demand for our services.


Investor enforcementIncreased scrutiny from stakeholders and others regarding climate change, as well as our sustainability practices, initiatives and reporting responsibilities, could result in additional costs or risks.

In recent years the investment community, including investment advisors and certain sovereign wealth, pension and endowment funds, has promoted the divestment of civil judgments against usfossil fuel equities and pressured lenders to cease or limit funding to companies engaged in the extraction of fossil fuel reserves. Such initiatives could ultimately interfere with our access to capital, business activities and operations.

In addition to such initiatives, sustainability matters more generally have been the subject of increased focus by investors, customers, investment funds, political advocacy groups, and other market and industry participants, as well as certain regulators, including in the U.S. and the EU. We publish an annual Sustainability Report, which includes disclosure of our sustainability practices, aspirations, targets and goals. Our disclosures on these matters rely on management’s expectations as of the date the statements are first made, as well as standards for measuring progress that are still in development and may change or fail to be more difficult.

Becauserealized. These expectations and standards may continue to evolve. Even so, our failure or inability to meet these targets, goals or evolving stakeholder expectations for sustainability practices and reporting and even the perception of such failure or inability may potentially harm our reputation and impact employee retention, customer relationships and access to capital, among other matters. For example, certain market participants use third-party benchmarks or scores to measure a company’s sustainability practices in making investment decisions and customers and suppliers may evaluate our sustainability practices or require that we adopt certain sustainability policies as a condition of awarding contracts. By electing to set and share publicly our corporate sustainability standards, our business may face increased scrutiny related to sustainability activities and be unable to satisfy all stakeholders. For example, some stakeholders and regulators have expressed or pursued opposing views, legislation, and investment expectations with respect to sustainability. As sustainability best-practices and voluntary or mandatory reporting standards continue to develop, we may incur increased costs related to sustainability monitoring and reporting and complying with sustainability initiatives, especially to the extent these standards are a public limited company incorporated under the Laws of England and Wales, investors could experience difficulty enforcing judgments obtained against us in U.S. courts.not harmonized or consistent.

Item 1C.Cybersecurity

We have less flexibility as a U.K. public limited company with respectcybersecurity program to certain aspectsassess, identify, and manage risks from cybersecurity threats. The Company’s cybersecurity program includes administrative, technical, and physical safeguards that address our information systems, including our IT and operational technology environments. The program is designed to ensure the confidentiality, security, integrity, and availability of capitalthose systems and the information residing therein.

Strategy and Risk Management:

Our cybersecurity strategy leverages administrative safeguards that include policies, procedures, and processes to assess, identify, and manage risks from cybersecurity threats. We have adopted a Cybersecurity Incident Response Policy (the “CIRP”), which provides a framework and guidance for investigating, containing, documenting and mitigating incidents, including reporting findings and keeping senior management than U.S. corporations due to increased shareholder approval requirements.

Directors of Delaware and other U.S. corporations may issue, without further shareholder approval, shareskey stakeholders informed and involved as appropriate.

Additionally, all of common stock authorized in their certificatesthe Company’s employees undertake an annual cybersecurity training program on how to identify characteristics of incorporation that were not already issued or reserved.  The business corporation lawsvarious cybersecurity threats, which is augmented by additional training and communications on IT and cybersecurity matters throughout the year. Periodically during the year, the Company’s IT department leads simulations of Delawarecybersecurity incidents with employees to test the organization’s ability to respond to a variety of cybersecurity-related scenarios.

Our policies, procedures, and processes are aligned with our technical tools, which include continuous security monitoring and alerting, an AI-based tool to facilitate cybersecurity incident identification and remediation, and other U.S. statestechnologies, to ensure the security of our systems and information. We also provide substantial flexibilityhave implemented certain physical safeguards, such as restricted access to areas containing critical IT and operational technology equipment, to mitigate risks to our physical environment.

Cybersecurity is integrated into our enterprise risk management ("ERM") process. Cybersecurity-related risks are included in establishingour ERM risk register, which are reviewed by internal stakeholders who designate the termsrelative level of preferred stock. However, English law provides that a boardseverity of directors may only allot shares with the prior authorization of an ordinary resolution of the shareholders,identified risks. The ERM risk register, which authorization must state the maximum amount of shares that may be allotted under itincludes any identified cybersecurity-related risks, is reviewed by our Executive Management Committee and specify the date on which it will expire, which must not be more than five years from the date on which the shareholder resolution is passed. An ordinary resolution was passed by shareholders at our last annual general meeting in 2017reported quarterly to authorize the allotment of additional shares for a one-year term and this authority was further increased by shareholders at an additional general meeting in October 2017. As this authority will expire in August 2018, an ordinary resolution will be put to shareholders at our next annual shareholder meeting seeking their approval to renew the board's authority to allot shares for an additional one-year term.

English law also generally provides shareholders pre-emption rights over new shares that are issued for cash. However, it is possible, where the board of directors, who then reviews the identified risks, mitigation plans and monitoring reports and provides oversight as appropriate.

Oversight:

The Audit Committee is generally authorized to allot shares, to exclude pre-emption rights by a special resolutionresponsible for, and actively engaged in, the oversight of our IT and cybersecurity program, including the oversight of risks from cybersecurity threats. All members of the shareholdersAudit Committee have prior work experience relating to cybersecurity or byhave obtained a provisioncertification or degree in cybersecurity. The Audit Committee, at least quarterly, receives reports from the Company’s Senior Director – Information Technology (“SDIT”) on, among other things, the Company’s cybersecurity incidents, risks and measures, training and organizational readiness. The board of directors is kept apprised of cybersecurity risk matters, including through participation in the articlesquarterly cybersecurity briefings to the Audit Committee that are described above. We have protocols by which certain cybersecurity incidents are escalated within the Company and, where appropriate, reported in a timely manner to the board of association. Such exclusiondirectors and Audit Committee.

At the management level, the SDIT and his team are responsible for leading enterprise-wide information security strategy, policy, standards, architecture and processes, including the assessment and management of pre-emption rights will commonly ceasematerial risks from cybersecurity threats. The Company’s SDIT reports to have effect at the same time asChief Financial Officer. The SDIT has extensive cybersecurity knowledge and skills, gained from over 25 years of relevant work experience. The SDIT is informed about and monitors the general allotment authorityprevention, detection, mitigation, and remediation of cybersecurity incidents in accordance with the CIRP and policies and procedures, which may include reports from the IT team. The SDIT also regularly reviews risk management measures implemented by the Company to which it relates is revoked or expires. Ifidentify and mitigate cybersecurity risks.

Third Parties and Assessments:

We engage third-party service providers in various capacities to enhance our internal cybersecurity capabilities. The Company engages consultants to assist with cybersecurity assessments, including with respect to cloud security and network vulnerability testing. Internal Audit, along with other internal stakeholders, including IT, determine the general allotment authority is renewed, the authority excluding pre-emption rights may also be renewed by a special resolution of the shareholders. A special resolution was passed,Company’s need for cybersecurity assessments in conjunction with an allotment authority atannual cybersecurity risk assessment process.

Further, pursuant to our last annual general shareholder meeting in 2017,CIRP, we have engaged third-party support under a retainer agreement to disapply pre-emption rights forenable an effective and timely response to a one-year termsignificant cybersecurity incident.

In addition to assessing our own cybersecurity preparedness, we also consider and evaluate cybersecurity risks associated with use of third-party service providers. We obtain Systems and Organization Controls ("SOC") 1 and SOC 2 reports, as applicable, from our third-party service providers which assess those entities' controls to cover security, availability, integrity, confidentiality and privacy. Any applicable findings of this authority wasthird-party assessment are analyzed by the appropriate employees and further increased by shareholders at an additional general meeting in October 2017. Asaction is taken as needed.

Impact of Cybersecurity Risks and Threats:

While we have not experienced any material cybersecurity threats or incidents as of the date of this authority will expire in August 2018, special resolutions willAnnual Report on Form 10-K, there can be put to shareholders at our next annual shareholder meeting seeking their approval to renew the board's authority to disapply pre-emption rights for an additional one-year term.



English law prohibits us from conducting "on-market purchases" as our sharesno guarantee that we will not be tradedthe subject of future successful attacks, threats or incidents. Additional information on a recognized investment exchangecybersecurity risks we face is discussed in “Item 1A. Risk Factors,” which should be read in conjunction with the U.K. English law also generally prohibits a company from repurchasing its own shares by way of "off-market purchases" without the approval by a special resolution of the shareholders of the terms of the contract by which the purchase(s) is affected. Such approval may only last for a maximum period of five years after the date on which the resolution is passed. A special resolution was passed at our annual shareholder meeting in May 2013 to permit the us to make "off-market" purchases of our own shares pursuant to certain purchase agreements for a five-year term.foregoing information.


We can provide no assurances that situations will not arise where such shareholder approval requirements for any of these actions would deprive our shareholders of substantial benefits.

Our articles of association contain anti-takeover provisions.



Certain provisions of our articles of association have anti-takeover effects, such as the ability to issue shares under the Rights Plan (as defined therein). These provisions are intended to ensure that any takeover or change of control of the Company is conducted in an orderly manner, all shareholders of the Company are treated equally and fairly and receive an optimum price for their shares and the long-term success of the Company is safeguarded. Under English law, it may not be possible to implement these provisions in all circumstances.

The Company is not subject to the U.K.'s Code on Takeovers and Mergers (the “Code”).

The Code only applies to an offer for a public company that is registered in the U.K. (or the Channel Islands or the Isle of Man) and the securities of which are not admitted to trading on a regulated market in the U.K. (or the Channel Islands or the Isle of Man) if the company is considered by the takeover panel (the "Takeover Panel") to have its place of central management and control in the U.K. (or the Channel Islands or the Isle of Man). This is known as the "residency test." The test for central management and control under the Code is different from that used by the U.K. tax authorities. Under the Code, the Takeover Panel will look to where the majority of the directors of the company are residents for the purposes of determining where the company has its place of central management and control. Accordingly, the Takeover Panel has previously indicated that the Code does not apply to the Company and the Company's shareholders therefore do not have the benefit of the protections the Code affords, including, but not limited to, the requirement that a person who acquires an interest in shares carrying 30% or more of the voting rights in the Company must make a cash offer to all other shareholders at the highest price paid in the 12 months before the offer was announced.

English law requires that we meet certain additional financial requirements before declaring dividends and returning funds to shareholders.

Under English law, we are only able to declare dividends and return funds to our shareholders out of the accumulated distributable reserves on our statutory balance sheet. Distributable reserves are a company’s accumulated, realized profits, so far as not previously utilized by distribution or capitalization, less its accumulated, realized losses, so far as not previously written off in a reduction or reorganization of capital duly made. Realized profits are created through the remittance of profits of certain subsidiaries to our parent company in the form of dividends.

English law also provides that a public company can only make a distribution if, among other things (a) the amount of its net assets (that is, the total excess of assets over liabilities) is not less than the total of its called up share capital and non-distributable reserves and (b) if, and to the extent that, the distribution does not reduce the amount of its net assets to less than that total.
We may be unable to remit the profits of our subsidiaries in a timely or tax efficient manner. If at any time we do not have sufficient distributable reserves to declare and pay quarterly dividends, we may undertake a reduction in the capital of the Company, in addition to the reduction in capital taken in 2014, to reduce the amount of our share capital and non-distributable reserves and to create a corresponding increase in our distributable reserves out of which future distributions to shareholders can be made. To comply with English law, a reduction of capital would be subject


to (a) approval of shareholders at a general meeting by special resolution; (b) confirmation by an order of the English Courts and (c) the Court order being delivered to and registered by the Registrar of Companies in England. If we were to pursue a reduction of capital of the Company as a course of action, and failed to obtain the necessary approvals from shareholders and the English Courts, we may undertake other efforts to allow the Company to declare dividends and return funds to shareholders.

Prior to stacking, upfront steps are taken to preserve the rig. This may include a quayside power source to dehumidify key equipment and/or provide electric current to the hull to prevent corrosion. Also, certain equipment may be removed from the rig for storage in a temperature-controlled environment. While stacked, large equipment that remains on the rig is periodically inspected and maintained by Ensco personnel. These steps are designed to reduce time and lower cost to reactivate the rig when market conditions improve.

(4)Rigs are under-going contract preparations for lease contracts with ARO drilling.

The equipment on our drilling rigs includes engines, drawworks,draw works, derricks, pumps to circulate drilling fluid, well control systems, drill string and related equipment. The engines power a top-drive mechanism that turns the drill string and drill bit so that the hole is drilled by grinding subsurface materials, which are then returned to the rig by the drilling fluid. The intended water depth, well depth and geological conditions are the principal factors that determine the size and type of rig most suitable for a particular drilling project.
 
Floater rigs consist of drillships and semisubmersibles. Drillships are purpose-built maritime vessels outfitted with drilling apparatus.  Drillships are self-propelled and can be positioned over a drill site through the use of a computer-controlled propellerpropellers or "thruster" (dynamic positioning) system.dynamic positioning systems.  Our drillships are capable of drilling in water depths of up to 12,000 feet and are suitable for deepwater drilling in remote locations because of their superior mobility and large load-carrying capacity.  Although drillships are most often used for deepwater drilling and exploratory well drilling, drillships can also be used as a platform to carry out well maintenance or completion work such as casing and tubing installation or subsea tree installations.
43





Semisubmersibles are mobile offshore drilling unitsrigs with pontoons and columns that are partially submerged at the drilling location to provide added stability during drilling operations. Semisubmersibles are held in a fixed location over the ocean floor either by being anchored to the sea bottom with mooring chains (moored semisubmersible rig) or dynamically positioned by computer-controlled propellers or "thrusters" (dynamically positioned semisubmersible rig) similar to that used by our drillships.  Moored semisubmersibles are most commonly used for drilling in water depths of 4,499 feet or less.  However, ENSCO 5006 and ENSCOVALARIS MS-1, which areis a moored semisubmersibles, aresemisubmersible, is capable of deepwater drilling in water depths greater than 5,000 feet.  Dynamically positioned semisubmersibles generally are outfitted for drilling in deeper water depths and are well-suited for deepwater development and exploratory well drilling. Further, we have threetwo hybrid semisubmersibles, ENSCO 8503, ENSCO 8504VALARIS DPS-3 and ENSCO 8505,VALARIS DPS-5, which leverage both moored and dynamically positioned configurations. This hybrid design provides multi-faceted drilling solutions to customers with both shallow water and deepwater requirements.
 
Jackup rigs stand on the ocean floor with their hull and drilling equipment elevated above the water on connected leg supports. Jackups are generally preferred over other rig types in shallow water depths of 400 feet or less, primarily because jackups provide a more stable drilling platform with above water well-control equipment. Our jackups are of the independent leg design where each leg can be fixed into the ocean floor at varying depths and equipped with a cantilever that allows the drilling equipment to extend outward from the hull over fixed platforms enabling safer drilling of both exploratory and development wells. The jackup hull supports the drilling equipment, jacking system, crew quarters, storage and loading facilities, helicopter landing pad and related equipment and supplies.
 
Over the life of a typical rig, many of the major systems are replaced due to normal wear and tear or technological advancements in drilling equipment. We believe all our rigs are in good condition. As of February 27, 2018, we ownedown all rigs in our fleet. We alsofleet and we manage the drilling operations for two platform rigs owned by third-parties. a third-party.

Item 3.  Legal Proceedings


Brazil Internal Investigation

Pride International LLC, formerly Pride International, Inc. (“Pride”), a company we acquired in 2011, commenced drilling operations in Brazil in 2001. In 2008, Pride entered into a drilling services agreement with Petrobras (the "DSA") for ENSCO DS-5, a drillship ordered from Samsung Heavy Industries, a shipyard in South Korea ("SHI"). Beginning in 2006, Pride conducted periodic compliance reviews of its business with Petrobras, and, after the acquisition of Pride, Ensco conducted similar compliance reviews.

We commenced a compliance review in early 2015 after the release of media reports regarding ongoing investigations of various kickback and bribery schemes in Brazil involving Petrobras. While conducting our compliance review, we became aware of an internal audit report by Petrobras alleging irregularities in relation to the DSA. Upon learning of the Petrobras internal audit report, our Audit Committee appointed independent counsel to lead an investigation into the alleged irregularities. Further, in June and July 2015, we voluntarily contacted the SEC and the DOJ, respectively, to advise them of this matter and of our Audit Committee’s investigation. Independent counsel, under the direction of our Audit Committee, has substantially completed its investigation by reviewing and analyzing available documents and correspondence and interviewing current and former employees involved in the DSA negotiations and the negotiation of the ENSCO DS-5 construction contract with SHI (the "DS-5 Construction Contract").

To date, our Audit Committee has found no credible evidence that Pride or Ensco or any of their current or former employees were aware of or involved in any wrongdoing, and our Audit Committee has found no credible evidence linking Ensco or Pride to any illegal acts committed by our former marketing consultant who provided services to Pride and Ensco in connection with the DSA. We, through independent counsel, have continued to cooperate with


the SEC and DOJ, including providing detailed briefings regarding our investigation and findings and responding to inquiries as they arise. We entered into a one-year tolling agreement with the DOJ that expired in December 2016. We extended our tolling agreement with the SEC for 12 months until March 2018.

Subsequent to initiating our Audit Committee investigation, Brazilian court documents connected to the prosecution of former Petrobras directors and employees as well as certain other third parties, including our former marketing consultant, referenced the alleged irregularities cited in the Petrobras internal audit report. Our former marketing consultant has entered into a plea agreement with the Brazilian authorities. On January 10, 2016, Brazilian authorities filed an indictment against a former Petrobras director. This indictment states that the former Petrobras director received bribes paid out of proceeds from a brokerage agreement entered into for purposes of intermediating a drillship construction contract between SHI and Pride, which we believe to be the DS-5 Construction Contract. The parties to the brokerage agreement were a company affiliated with a person acting on behalf of the former Petrobras director, a company affiliated with our former marketing consultant, and SHI. The indictment alleges that amounts paid by SHI under the brokerage agreement ultimately were used to pay bribes to the former Petrobras director. The indictment does not state that Pride or Ensco or any of their current or former employees were involved in the bribery scheme or had any knowledge of the bribery scheme.

On January 4, 2016, we received a notice from Petrobras declaring the DSA void effective immediately. Petrobras’ notice alleges that our former marketing consultant both received and procured improper payments from SHI for employees of Petrobras and that Pride had knowledge of this activity and assisted in the procurement of and/or facilitated these improper payments. We disagree with Petrobras’ allegations. See "DSA Dispute" below for additional information.
In August 2017, one of our Brazilian subsidiaries was contacted by the Office of the Attorney General for the Brazilian state of Paraná in connection with a criminal investigation procedure initiated against agents of both SHI and Pride in relation to the DSA.  The Brazilian authorities requested information regarding our compliance program and the findings of our internal investigations. We are cooperating with the Office of the Attorney General and have provided documents in response to their request.  We cannot predict the scope or ultimate outcome of this procedure or whether any other governmental authority will open an investigation into Pride’s involvement in this matter, or if a proceeding were opened, the scope or ultimate outcome of any such investigation. If the SEC or DOJ determines that violations of the FCPA have occurred, or if any governmental authority determines that we have violated applicable anti-bribery laws, they could seek civil and criminal sanctions, including monetary penalties, against us, as well as changes to our business practices and compliance programs, any of which could have a material adverse effect on our business and financial condition. Our customers, business partners and other stakeholders could seek to take actions adverse to our interests. Further, investigating and resolving such allegations is expensive and could consume significant management time and attention. Although our internal investigation is substantially complete, we cannot predict whether any additional allegations will be made or whether any additional facts relevant to the investigation will be uncovered during the course of the investigation and what impact those allegations and additional facts will have on the timing or conclusions of the investigation. Our Audit Committee will examine any such additional allegations and additional facts and the circumstances surrounding them.
DSA Dispute

As described above, on January 4, 2016, Petrobras sent a notice to us declaring the DSA void effective immediately, reserving its rights and stating its intention to seek any restitution to which it may be entitled. We disagree with Petrobras’ declaration that the DSA is void. We believe that Petrobras repudiated the DSA and have therefore accepted the DSA as terminated on April 8, 2016 (the "Termination Date"). At this time, we cannot reasonably determine the validity of Petrobras' claim or the range of our potential exposure, if any. As a result, there can be no assurance as to how this dispute will ultimately be resolved.

We did not recognize revenue for amounts owed to us under the DSA from the beginning of the fourth quarter of 2015 through the Termination Date as we concluded that collectability of these amounts was not reasonably assured. Additionally, our receivables from Petrobras related to the DSA from prior to the fourth quarter of 2015 are fully


reserved in our consolidated balance sheet as of December 31, 2017 and 2016. In August 2016, we initiated arbitration proceedings in the U.K. against Petrobras seeking payment of all amounts owed to us under the DSA, in addition to any other amounts to which we are entitled, and intend to vigorously pursue our claims. Petrobras subsequently filed a counterclaim seeking restitution of certain sums paid under the DSA less value received by Petrobras under the DSA. There can be no assurance as to how this arbitration proceeding will ultimately be resolved.

In November 2016, we initiated separate arbitration proceedings in the U.K. against SHI for any losses we incur in connection with the foregoing Petrobras arbitration. SHI subsequently filed a statement of defense disputing our claim. In January 2018, the arbitration tribunal for the SHI matter issued an award on liability fully in Ensco’s favor.  SHI is liable to us for $10 million or damages that we can prove.  As the losses suffered by us will depend in part on the outcome of the Petrobras arbitration described above, the amount of damages to be paid by SHI will be determined after the conclusion of the Petrobras arbitration.  We are unable to estimate the ultimate outcome of recovery for damages at this time.

Pride FCPA Investigation

During 2010, Pride and its subsidiaries resolved their previously disclosed investigations into potential violations of the U.S. Foreign Corrupt Practices Act of 1977 (the "FCPA") with the DOJ and SEC. The settlement with the DOJ included a deferred prosecution agreement (the "DPA") between Pride and the DOJ and a guilty plea by Pride Forasol S.A.S., one of Pride’s subsidiaries, to FCPA-related charges. During 2012, the DOJ moved to (i) dismiss the charges against Pride and end the DPA one year prior to its scheduled expiration; and (ii) terminate the unsupervised probation of Pride Forasol S.A.S. The Court granted the motions.

Pride has received preliminary inquiries from governmental authorities of certain countries referenced in its settlements with the DOJ and SEC. We could face additional fines, sanctions and other penalties from authorities in these and other relevant jurisdictions, including prohibition of our participating in or curtailment of business operations in certain jurisdictions and the seizure of rigs or other assets. At this stage of such inquiries, we are unable to determine what, if any, legal liability may result. Our customers in certain jurisdictions could seek to impose penalties or take other actions adverse to our business. We could also face other third-party claims by directors, officers, employees, affiliates, advisors, attorneys, agents, stockholders, debt holders or other stakeholders. In addition, disclosure of the subject matter of the investigations and settlements could adversely affect our reputation and our ability to obtain new business or retain existing business, to attract and retain employees and to access the capital markets.

We cannot currently predict what, if any, actions may be taken by any other applicable government or other authorities or our customers or other third parties or the effect any such actions may have on our financial position, operating results and cash flows.

Environmental Matters
 
We are currently subject to pending notices of assessment relating to spills of drilling fluids, oil, brine, chemicals, grease or fuel from drilling rigs operating offshore Brazil from 2008 to 2017,2019, pursuant to which the governmental authorities have assessed, or are anticipated to assess, fines. We have contested these notices and appealed certain adverse decisions and are awaiting decisions in these cases. Although we do not expect final disposition of these assessments to have a material adverse effect on our financial position, operating results and cash flows, there can be no assurance as to the ultimate outcome of these assessments. A $190,000$0.4 million liability related to these matters was included in accruedAccrued liabilities and other on our consolidated balance sheetConsolidated Balance Sheet as of December 31, 2017.2023 included in "Item 8. Financial Statements."
We currently are subject to a pending administrative proceeding initiated during 2009 by a Spanish government authority seeking payment in an aggregate amount of approximately $3.0 million, for an alleged environmental spill originating from ENSCO 5006 while it was operating offshore Spain. Our customer has posted guarantees with the Spanish government to cover potential penalties. Additionally, we expect to be indemnified for any payments resulting from this incident by our customer under the terms of the drilling contract. A criminal investigation of the incident was initiated during 2010 by a prosecutor in Tarragona, Spain, and the administrative proceedings have been suspended


pending the outcome of this investigation. We do not know at this time what, if any, involvement we may have in this investigation.
We intend to vigorously defend ourselves in the administrative proceeding and any criminal investigation. At this time, we are unable to predict the outcome of these matters or estimate the extent to which we may be exposed to any resulting liability. Although we do not expect final disposition of this matter to have a material adverse effect on our financial position, operating results and cash flows, there can be no assurance as to the ultimate outcome of the proceedings.


Other Matters


In addition to the foregoing, we are named defendants or parties in certain other lawsuits, claims or proceedings incidental to our business and are involved from time to time as parties to governmental investigations or proceedings, including matters related to taxation, arising in the ordinary course of business. Although the outcome of such lawsuits or other proceedings cannot be predicted with certainty and the amount of any liability that could arise with respect to such lawsuits or other proceedings cannot be predicted accurately, we do not expect these matters to have a material adverse effect on our financial position, operating results andor cash flows.

Our Board of Directors declared a $0.01 quarterly cash dividend for the first quarter of 2018. We currently intend to continue paying dividends for the foreseeable future. In October 2017, we amended our revolving credit facility, which 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.

The declaration and amount of future dividends is at the discretion of our Board of Directors and could change in future periods. In the future, our Board of Directors may, without advance notice, determine to reduce or suspend our dividend in order to improve our financial flexibility and best position us for long-term success. When evaluating dividend payment timing and amounts, our Board of Directors considers several factors, including our profitability, liquidity, financial condition, market outlook, reinvestment opportunities and capital requirements.

Exchange Controls

There are no U.K. government laws, decrees or regulations that restrict or affect the export or import of capital, including but not limited to, foreign exchange controls on remittance ofany dividends on our ordinary sharesCommon Shares. Our Indenture and the Credit Agreement include provisions that limit our ability to pay dividends.

Bermuda Tax

We have been designated by the Bermuda Monetary Authority as a non-resident for Bermuda exchange control purposes. This designation allows us to engage in transactions in currencies other than the Bermudian dollar, and there are no restrictions on our ability to transfer funds (other than funds denominated in Bermudian dollars) in and out of Bermuda or on the conductto pay dividends to United States residents who are holders of our operations.Common Shares.




U.K. Taxation
The following paragraphs are intended to be a general guide to current U.K.At the present time, there is no Bermuda income or profits tax, law and what is understood to be HMRC practice applying as of the date of this report (both of which are subject to change at any time, possibly with retrospective effect)withholding tax, capital gains tax, capital transfer tax, estate duty or inheritance tax payable by us or by our shareholders in respect of the taxation of capital gains, the taxation of dividends paid by us and stamp duty and SDRT on the transfer of our shares. In addition, the following paragraphs relate only to persons who for U.K. tax purposes are beneficial owners of the shares (“shareholders”).


These paragraphs may not relate to certain classes of holders or beneficial owners of shares, such as our employees or directors, persons who are connected with us, persons who could be treated for U.K. tax purposes as holding their shares as carried interest, insurance companies, charities, collective investment schemes, pension schemes, trustees or persons who hold shares other than as an investment, or U.K. resident individuals who are not domiciled in the U.K. or who are subject to split-year treatment.

These paragraphs do not describe all of the circumstances in which shareholders may benefit from an exemption or relief from taxation. It is recommended that all shareholders obtain their own taxation advice. In particular, any shareholders who are non-U.K. resident or domiciled are advised to consider the potential impact of any relevant double tax treaties, including the Convention between the United States of America and the United Kingdom for the Avoidance of Double Taxation with respect to Taxes on Income, to the extent applicable.

U.K. Taxation of Dividends
U.K. Withholding Tax - Dividends paid by us will not be subject to any withholding or deduction for, or on account of, U.K. tax, irrespective of the residence or the individual circumstances of the shareholders.

U.K. Income Tax - An individual shareholder who is resident in the U.K. may, depending on his or her individual circumstances, be subject to U.K. income tax on dividends received from us. An individual shareholder who is not resident in the U.K. will not be subject to U.K. income tax on dividends received from us, unless that shareholder carries on (whether alone or in partnership) any trade, profession or vocation through a branch or agency in the U.K. and shares are used by, or held by or for, that branch or agency. In these circumstances, the non-U.K. resident shareholder may, depending on his or her individual circumstances, be subject to U.K. income tax on dividends received from us.

The tax treatment of dividends paid by the Company to individual shareholders is as follows:

dividends paid by the Company will not carry a tax credit,

all dividends received by an individual shareholder from the Company (or from other sources) will, except to the extent that they are earned through an Individual Savings Account ("ISA"), self-invested pension plan or other regime which exempts the dividends from income tax, form part of the shareholder's total income for income tax purposes,

a nil rate of income tax will apply to the first £5,000 of taxable dividend income received by an individual shareholder in the tax year 2017/2018, which will reduce to £2,000 in the tax year 2018/2019 (the “Nil Rate Amount”), regardless of what tax rate would otherwise apply to that dividend income,

any taxable dividend income received by an individual shareholder in a tax year in excess of the Nil Rate Amount will be taxed at a special rate, as set out below, and

that tax will be applied to the amount of the dividend income actually received by the individual shareholder (rather than to a grossed-up amount).



Where a shareholder’s taxable dividend income for a tax year exceeds the Nil Rate Amount, the excess amount (the “Relevant Dividend Income”) will be subject to income tax:

at the rate of 7.5%, to the extent that the Relevant Dividend Income falls below the threshold for the higher rate of income tax,

at the rate of 32.5%, to the extent that the Relevant Dividend Income falls above the threshold for the higher rate of income tax but below the threshold for the additional rate of income tax, or

at the rate of 38.1%, to the extent that the Relevant Dividend Income falls above the threshold for the additional rate of income tax.

In determining whether and, if so, to what extent the Relevant Dividend Income falls above or below the threshold for the higher rate of income tax or, as the case may be, the additional rate of income tax, the shareholder’s total dividend income for the tax year in question (including the part within the Nil Rate Amount) will, as noted above, be treated as the highest part of the shareholder’s total income for income tax purposes.
U.K. Corporation Tax - Unless an exemption is available (as discussed below), a corporate shareholder that is resident in the U.K. will be subject to U.K. corporation tax on dividends received from us. A corporate shareholder that is not resident in the U.K. will not be subject to U.K. corporation tax on dividends received from us, unless that shareholder carries on a trade in the U.K. through a permanent establishment in the U.K. and the shares are used by, for or held by or for, the permanent establishment. In these circumstances, the non-U.K. resident corporate shareholder may, depending on its individual circumstances (and if no exemption is available), be subject to U.K. corporation tax on dividends received from us.

The main rate of corporation tax payable with respect to dividends received from us in the financial year 2017 is 19%, and will be 19% for the financial year 2018. If dividends paid by us fall within any of the exemptions from U.K. corporation tax set out in Part 9A of the U.K. Corporation Tax Act 2009, the receipt of the dividend by a corporate shareholder generally will be exempt from U.K. corporation tax. Generally, the conditions for one or more of those exemptions from U.K. corporation tax on dividends paid by us should be satisfied, although the conditions that must be satisfied in any particular case will depend on the individual circumstances of the relevant corporate shareholder.

Shareholders that are regarded as small companies should generally be exempt from U.K. corporation tax on dividends received from us, unless the dividends are received as part of a tax advantage scheme. Shareholders that are not regarded as small companies should generally be exempt from U.K. corporation tax on dividends received from us on the basis that the shares should be regarded as non-redeemable ordinary shares. Alternatively, shareholders that are not small companies should also generally be exempt from U.K. corporation tax on dividends received from us if they hold shares representing less than 10% of our issued share capital, would be entitled to less than 10% of the profits available for distribution to our equity-holders and would be entitled on a winding up to less than 10% of our assets available for distribution to such equity-holders. In certain limited circumstances, the exemption from U.K. corporation tax will not apply to such shareholders if a dividend is made as part of a scheme that has a main purpose of falling within the exemption from U.K. corporation tax.

U.K. Taxation of Capital Gains
U.K. Withholding Tax - Capital gains accruing to non-U.K. resident shareholders on the disposal of shares will not be subject to any withholding or deduction for or on account of U.K. tax, irrespective of the residence or the individual circumstances of the relevant shareholder.



U.K. Capital Gains Tax - A disposal of shares by an individual shareholder who is resident in the U.K. may, depending on his or her individual circumstances, give rise to a taxable capital gain or an allowable loss for the purposes of U.K. capital gains tax (“CGT”). An individual shareholder who temporarily ceases to be resident or ordinarily resident in the U.K. for a period of less than five years and who disposes of his or her shares during that period of temporary non-residence may be liable for CGT on a taxable capital gain accruing on the disposal on his or her return to the U.K. under certain anti-avoidance rules.

An individual shareholder who is not resident in the U.K. will not be subject to CGT on capital gains arising on the disposal of their shares, unless that shareholder carries on a trade, profession or vocation in the U.K. through a branch or agency in the U.K. and the shares were acquired, used in or for the purposes of the branch or agency or used in or for the purposes of the trade, profession or vocation carried on by the shareholder through the branch or agency. In these circumstances, the relevant non-U.K. resident shareholder may, depending on his or her individual circumstances, be subject to CGT on chargeable gains arising from a disposal of his or her shares. The rate of CGT in the tax year 2017/2018 is 10% for basic rate taxpayers and 20% for higher and additional rate taxpayers, and is expected to be the same in the tax year 2018/2019.

U.K. Corporation Tax - A disposal of shares by a corporate shareholder resident in the U.K. may give rise to a chargeable gain or an allowable capital loss for the purposes of U.K. corporation tax. A corporate shareholder not resident in the U.K. will not be liable for U.K. corporation tax on chargeable gains accruing on the disposal of its shares, unless that shareholder carries on a trade in the U.K. through a permanent establishment in the U.K. and the shares were acquired, used in or for the purposes of the permanent establishment or used in or for the purposes of the trade carried on by the shareholder through the permanent establishment. In these circumstances, the relevant non-U.K. resident shareholder may, depending on its individual circumstances, be subject to U.K. corporation tax on chargeable gains arising from a disposal of its shares.

The financial year for U.K. corporation tax purposes runs from April 1 to March 31. The main rate of U.K. corporation tax on chargeable gains is 19% in the financial year 2017 and 19% in the financial year 2018. Corporate shareholders will be entitled to an indexation allowance in computing the amount of a chargeable gain accruing on a disposal of the shares, which will provide relief for the effects of inflation by reference to movements in the U.K. retail price index.

If the conditions of the applicable shareholding exemption are satisfied in relation to a chargeable gain accruing to a corporate shareholder on a disposal of its shares, the chargeable gain will be exempt from U.K. corporation tax. The conditions of the substantial shareholding exemption that must be satisfied will depend on the individual circumstances of the relevant corporate shareholder. One of the conditions of the substantial shareholding exemption that must be satisfied is that the corporate shareholder must have held a substantial shareholding in the Company throughout a 12-month period beginning not more than six years before the day on which the disposal takes place. Ordinarily, a corporate shareholder will not be regarded as holding a substantial shareholding in us, unless it (whether alone, or together with other group companies) directly holds not less than 10% of our ordinary share capital.

U.K. Stamp Duty and SDRT
The discussion below relates to shareholders wherever resident but not to holders such as market makers, brokers, dealers and intermediaries, to whom special rules apply. Special rules also apply in relation to certain stock lending and repurchase transactions.

Transfer of Shares held in book entry form via DTC - A transfer of shares held in book entry (i.e., electronic) form within the facilities of the DTC will not be subject to U.K. stamp duty or SDRT.



Transfers of Shares out of, or outside of, DTC - Subject to an exemption for certain low value transactions, a transfer of shares from within the DTC system out of that system or any transfer of shares that occurs entirely outside the DTC system generally will be subject to a charge to ad valorem U.K. stamp duty (normally payable by the transferee) at 0.5% of the purchase price of the shares (rounded up to the nearest multiple of £5). SDRT generally will be payable on an unconditional agreement to transfer such shares at 0.5% of the amount or value of the consideration for the transfer. However, such liability for SDRT generally will be cancelled and any SDRT paid will be refunded if the agreement is completed by a duly-stamped transfer within six years of either the date of the agreement or, if the agreement was conditional, the date when the agreement became unconditional.

We have put in place arrangements to require that shares held outside the facilities of DTC cannot be transferred into such facilities (including where shares are re-deposited into DTC by an existing shareholder) until the transferor of the shares has first delivered the shares to a depository we specified, so that SDRT may be collected in connection with the initial delivery to the depository. Before such transfer can be registered in our books, the transferor will be required to put in the depository funds to settle the resultant liability for SDRT, which will be 1.5% of the value of the shares, and to pay the transfer agent such processing fees as may be established from time to time.

Following a decision of the European Court of Justice in 2009 and a decision of the U.K. First-Tier Tax Tribunal in 2012, HMRC has announced that it will not seek to apply the 1.5% charge to stamp duty or SDRT on the issuance of shares (or, where it is integral to the raising of new capital, the transfer of new shares) into depository receipt or clearance systems, such as DTC. Thus, the 1.5% U.K. stamp duty or SDRT charge will apply only to the transfer of existing shares to clearance services or depositary receipt systems in circumstances where the transfer is not integral to the raising of new capital (for example, where shares are re-deposited into DTC by an existing shareholder). Investors should, however, be aware that this area may be subject to further developments in the future.
The above statements are intended only as a general guide to the current U.K. stamp duty and SDRT position. Transfers to certain categories of persons are not liable to U.K. stamp duty or SDRT and transfers to others may be liable at a higher rate than discussed above.

During the quarter ended December 31, 2017, equity securities were repurchased from employees and non-employee directors by an affiliated employee benefit trust in connection with the settlement of income tax withholding obligations arising from the vesting of share awards.  Such securities remain available for re-issuance in connection with employee share awards.

(2)
During 2013, our shareholders approved a new share repurchase program. Subject to certain provisions under English law, including the requirement of Ensco plc to have sufficient distributable reserves, we may repurchase up to a maximum of $2.0 billion in the aggregate under the program, but in no case more than 35.0 million shares. The program terminates in May 2018. In October 2017, we amended our revolving credit facility, which 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.

Atwood Merger

On May 29, 2017, we entered into an Agreement and Plan of MergerApril 30, 2021 (the “Merger Agreement”) with Atwood and Echo Merger Sub, LLC, our wholly-owned subsidiary, and on October 6, 2017 (the "Merger"Effective Date"), we successfully completed our acquisition of Atwood pursuant to the Merger Agreement (the “Merger”).

The Merger is expected to strengthen our position as the leader in offshore drilling across a wide range of water depths around the world. The Merger significantly enhances the capabilities of our rig fleetfinancial restructuring and improves our ability to meet future customer demandtogether with the highest-specification assets.
AsDebtors emerged from the Chapter 11 Cases. Upon emergence from the Chapter 11 Cases, we eliminated $7.1 billion of debt and obtained a result of$520.0 million capital injection by issuing the Merger, Atwood shareholders received 1.60 Ensco Class A Ordinary sharesFirst Lien Notes. See “Note 8 - Debt" to our consolidated financial statements included in "Item 8.

Our Industry


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. Low demand and excess supply can independently affect day rates and utilization of drilling rigs. Therefore, adverse changes in either of these factors can result in adverse changes in our industry. While the cost of moving a rig and the availability of rig-moving vessels may cause the balance of supply and demand to vary somewhat between regions, significant variations betweenmostregions are generally of a short-term nature due to rig mobility.




Drilling Rig Demand

DemandIn recent years, oil prices have experienced significant volatility as a result of the global COVID-19 pandemic, production disputes among major oil producing countries and various other factors. This volatility meaningfully impacted both the supply of, and demand for, drilling rigs is directly relatedoffshore rigs. Since 2021, oil prices have become relatively more stable due to, among other factors, rebounding demand for hydrocarbons, a measured approach to production increases by OPEC+ members, reduction in supply due to Russia’s invasion of Ukraine and the regionalsubsequent sanctions placed on Russia, and worldwidea focus on cash flow and returns by major exploration and production companies. In 2023, prices have remained at levels that are supportive of offshore exploration and development spending byactivity. The more constructive oil price environment has led to an improvement in contracting and gas companies.  Offshore exploration and development spending, which is beyondtendering activity for our control, may fluctuate substantially from year-to-year and from region-to-region.industry.


The sustained declineRig attrition in oil pricesthe industry over the past several years from 2014 highs causedlast decade, particularly for floaters, has resulted in a significant decline in thesmaller global fleet of rigs that is available to meet customer demands. In addition, demand for offshore drilling services continues to improve as many projects became uneconomical, resulting in fewer market tenders in recent periods. Operators significantly reduced their capital spending budgets, includingevidenced by increasing global utilization and day rates for offshore drilling rigs. Consequently, our outlook for the cancellation or deferral of existing programs. Declines in capital spending levels, together with the oversupply of rigs,offshore drilling business is positive.

Inflationary pressures remain elevated and have resulted in significantly reducedincreased personnel costs as well as in the prices of goods and services required to operate our rigs or execute capital projects. We expect that our costs will continue to rise in the near term and although certain of our long-term contracts contain provisions for escalating costs, we cannot predict with certainty our ability to successfully claim recoveries of higher costs from our customers under these contractual stipulations. Despite the inflationary trends and macroeconomic uncertainty, we continue to see recovery in our industry.

Backlog

Our contract drilling backlog reflects commitments, represented by signed drilling contracts, and is calculated by multiplying the contracted operating day rate by the contract period. The contracted day rate excludes certain types of lump sum fees for rig mobilization, demobilization, contract preparation, as well as customer reimbursables and bonus opportunities. Our backlog excludes ARO's backlog, but includes backlog from our rigs leased to ARO at the contractual rates, which are subject to adjustment under the terms of the shareholder agreement governing the joint venture.

The ARO backlog presented below is 100% of ARO's backlog and utilization.is inclusive of backlog on both ARO owned rigs and rigs leased from us. As an unconsolidated 50/50 joint venture, when ARO realizes revenue from its backlog, 50% of the earnings thereon would be reflected in our results in equity in earnings of ARO in our Consolidated Statement of Operations. The earnings from ARO backlog with respect to rigs leased from us will be net of, among other things, payments to us under bareboat charters for those rigs. 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 contracting environment remained challengingfollowing table summarizes our and 100% of ARO's contract backlog of business as of February 15, 2024 and February 21, 2023 (in millions):

(1)The increase in Floaters is primarily due to long-term contracts for VALARIS DS-4 and VALARIS DS-8 offshore drilling contractors during 2017. Although oil prices have rebounded significantly offBrazil, VALARIS DS-7 offshore West Africa, VALARIS DS-16 in the 12-year lows experienced during early 2016U.S. Gulf of Mexico and a 250-day contract extension for VALARIS DS-15 offshore Brazil, which resulted in incremental aggregate backlog of approximately $1.7 billion. These increases were partially offset by revenues realized.

(2)The increase in Jackups is primarily due to levels above $60 per barrel, we expectcontract awards and extensions for VALARIS 120, VALARIS 72, VALARIS 92, VALARIS 121, VALARIS 107, VALARIS 118, VALARIS 249 and VALARIS Stavanger which resulted in incremental aggregate backlog of approximately $620.0 million. These increases were partially offset by revenues realized.

(3)Other includes the recoverybareboat charter backlog for the jackup rigs leased to ARO to fulfill contracts between ARO and Saudi Aramco in demandaddition to backlog for our managed rig services. Substantially all the operating costs for jackups leased to ARO through the bareboat charter agreements will be borne by ARO.

(4)The increase in ARO backlog is primarily due to an eight-year contract for each of the two newbuild rigs, the first of which was delivered in October 2023 and the second is expected to be gradual with different segmentsdelivered in the first half of the market recovering more quickly than others.2024. These two contracts resulted in incremental aggregate backlog of approximately $924.0 million, which was partially offset by revenues realized.

While the short-term dynamics of the market remain challenging, we have seen new opportunities for work increase as shallow water activity recovers and jackup utilization stabilizes. Moreover, new floater contracts have increased over the past year and contract terms are beginning to lengthen as customers take advantage of lower day rates. However, we believe further improvements in demand coupled with reductions in rig supply are necessary to generate meaningful increases in day rates.


The intense pressure on operating day ratesfollowing table summarizes our and 100% of ARO's contract backlog of business as of February 15, 2024 and the periods in recentwhich revenues are expected to be realized (in millions):

ARO$603.3 $536.9 $997.9 $2,138.1 

The amount of actual revenues earned and the actual periods has resultedduring which revenues are earned will be different from amounts disclosed in rates that approximate direct operating expenses in certain instances. Therefore, we expect our results from operations to continue to decline into 2018 as current contracts with above market rates expire and new contracts are executed at lower rates.

Because many factors that affect the market for offshore exploration and development are beyond our control and because rig demand can change quickly, it is difficult for us to predict future industry conditions, demand trends or operating results. Periods of low rig demand often result in excess rig supply, which generally results in reductions in utilization and day rates. Conversely, periods of high rig demand often result in a shortage of rigs, which generally results in increased utilization and day rates.

Drilling Rig Supply

Drilling rig supply significantly exceeds drilling rig demand for both floaters and jackups. The decline in customer capital expenditure budgets over the past several years has ledbacklog calculations due to a lack of contracting opportunities resulting in global fleet attrition. Since the beginningpredictability of various factors, including unscheduled repairs, maintenance requirements, weather delays, contract terminations or renegotiations and other factors.

Our drilling contracts generally contain provisions permitting early termination of the downturn, drilling contractors have retired approximately 100 floaters and 50 jackups. When demand for offshore drilling ultimately improves, we expect that newer, more capable rigs will becontract if the first to obtain contract awards, increasing the likelihood that older, less capable rigs do not return to the global active fleet.

Approximately 30 floaters older than 30 years are idle, approximately 20 additional floaters older than 30 years have contracts expiringrig is lost or destroyed or by the end of 2018 without follow-on work and a further nine 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 recertify these aging rigs may prove cost prohibitive. Drilling contractors will likely elect to scrap or cold-stack some or all of these rigs.

Approximately 125 jackups older than 30 years are idle, and approximately 65 jackups that are 30 years or older have contracts expiring by the end of 2018 without follow-on work. Expenditures required to recertify 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 2018 and into 2019.



There are 43 newbuild drillships and semisubmersibles reported to be under construction, of which 22 are scheduled to be delivered before the end of 2018. Most newbuild floaters are uncontracted. Several newbuild deliveries have already been delayed into future years, and we expect that more uncontracted newbuilds will be delayed or cancelled.

There are 92 newbuild jackups reported to be under construction, of which 61 are scheduled to be delivered before the end of 2018. Most newbuild jackups are uncontracted. Over the past year, some jackup orders have been cancelled, and many newbuild jackups have been delayed. We expect that additional rigs may be delayed or cancelled given limited contracting opportunities.

Liquidity, Backlog and Debt Maturities

We have historically relied on our cash flow from continuing operations to meet liquidity needs and fund the majority of our cash requirements. We periodically rely on the issuance of debt and/or equity securities to supplement our liquidity needs. Based on our balance sheet, our contractual backlog and $2.0 billion available under our revolving credit facility, we expect to fund our short-term and long-term liquidity needs, including contractual obligations and anticipated capital expenditures, dividends and working capital requirements, from cash and cash equivalents, short-term investments, operating cash flows and, if necessary, funds borrowed under our revolving credit facility or other future financing arrangements. During 2017 and in early 2018, we executed several transactions to maximize our liquidity.

Cash and Debt

As of December 31, 2017, we had $4.8 billion in total debt outstanding, representing 35.2% of our total capitalization. We also had $885.4 million in cash and short-term investments and $2.0 billion undrawn capacity under our credit facility. Adjusted on a pro forma basis for the January 2018 debt offering and subsequent debt repurchases discussed below, our December 31, 2017 cash and short-term investments totaled $1.2 billion and debt totaled $5.1 billion, or 36.7% of our total capitalization.
In January 2018, we issued $1.0 billion aggregate principal amount of unsecured 7.75% senior notes due 2026 (the "2026 Notes"), net of debt issuance costs of $16.5 million. Net proceeds of $983.5 million from the 2026 Notes were partially used to fund the repurchase and redemption of $237.6 million principal amount of our 8.50% senior notes due 2019, $256.6 million principal amount of our 6.875% senior notes due 2020 and $156.2 million principal amount of our 4.70% senior notes due 2021. We expect to recognize a pre-tax loss on debt extinguishment of $18.2 million during the first quarter of 2018.

Following the January 2018 debt offering, repurchases and redemption, our only debt maturities until 2024 are $194.3 million during 2020 and $113.5 million during 2021.
Upon closing of the Merger, we utilized acquired cash of $445.4 million and cash on hand from the liquidation of short-term investments to repay Atwood's debt and accrued interest of $1.3 billion. We amended our credit facility upon closing to extend the final maturity date by two years. Previously, our credit facility had a borrowing capacity of $2.25 billion through September 2019 that declined to $1.13 billion through September 2020. Subsequent to the amendment, our borrowing capacity is $2.0 billion through September 2019 and declines to $1.3 billion through September 2020 and to $1.2 billion through September 2022. The credit facility, as amended, requires us to maintain a total debt to total capitalization ratio that is less than or equal to 60%.

In January 2017, through a private-exchange transaction, we repurchased $649.5 million of our outstanding debt with $332.5 million of cash and $332.0 million of newly issued 8.00% senior notes due 2024. During the remainder of the year, we repurchased $194.1 million aggregate principal amount of our outstanding debt on the open market for $204.5 million of cash and recognized an insignificant pre-tax gain, net of discounts, premiums and debt issuance costs.



Backlog

As of December 31, 2017, our backlog was $2.8 billion as compared to $3.6 billion as of December 31, 2016. Our backlog declined primarily due to revenues realized during the year, partially offset by new contract awards and contract extensions. As older, higher day rate contracts expire, we will likely experience further declines in backlog, which will result in a decline in revenues and operating cash flows during 2018. 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 27, 2018 and February 28, 2017, respectively. See “Item 1A. Risk Factors - We might suffer losses if our customers terminate or seek to renegotiate our contracts,customer if operations are suspended for a specified period of time due to breakdown of major rig equipment, unsatisfactory performance, "force majeure" events beyond the control of either party or interrupted or if a rig becomes a total loss” regarding the ENSCO DS-8 contract.

Drilling Rig Construction and Delivery

We remain focused onother specified conditions. In addition, our long-established strategy of high-grading our fleet, as evidenced by the recently completed Merger. During the three-year period ended December 31, 2017, we invested approximately $1.9 billion in the construction of new drilling rigs. We will continue to invest in the expansion and high-grading of our fleet or execute other strategic transactions to optimize our asset portfolio when we believe attractive opportunities exist.

We believe our remaining capital commitments will primarily be funded from cash and cash equivalents, short-term investments, operating cash flows and, if necessary, funds borrowed under our revolving credit facility. We may decide to access debt and/or equity markets to raise additional capital or increase liquidity as necessary.

Floaters

We previously entered into agreements with Samsung Heavy Industries to construct three ultra-deepwater drillships (ENSCO DS-8, ENSCO DS-9 and ENSCO DS-10). During 2015, we accepted delivery of ENSCO DS-8 and ENSCO DS-9. ENSCO DS-8 commenced drilling operations under a long-term contract in Angola during 2015 and ENSCO DS-9 is actively being marketed. During 2017, we executed a one-year contract with five one-year priced options for ENSCO DS-10. As a resultcontracts generally permit early termination of the contract award, we accelerated delivery of ENSCO DS-10, which had previously been deferred into 2019,by the customer for convenience (without cause), exercisable upon advance notice to us, and made the final milestonein certain cases without making an early termination payment of $75.0 million. We expect ENSCO DS-10 to commence drilling operations offshore Nigeria in March 2018.

In connection with the Merger, we acquired two ultra-deepwater drillships, ENSCO DS-13 (formerly Atwood Admiral) and ENSCO DS-14 (formerly Atwood Archer), which are currently under construction in the Daewoo Shipbuilding & Marine Engineering Co. Ltd. ("DSME") yard in South Korea. ENSCO DS-13 and ENSCO DS-14 are scheduled for delivery in the third quarter of 2019 and second quarter of 2020, respectively. Upon delivery, the remaining milestone payments and accrued interest thereon mayus. There can be financed through a promissory note with the shipyard for each rig. The promissory notes will bear interest at a rate of 5% per annum with a maturity date of December 31, 2022 andno assurances that our customers will be secured by a mortgage on each respective rig.able to or willing to fulfill their contractual commitments to us.  

Jackups

During 2014, we entered into an agreement with Lamprell Energy Limited ("Lamprell") to construct two premium jackup rigs. ENSCO 140 and ENSCO 141 are significantly enhanced versions of the LeTourneau Super 116E jackup design and incorporate Ensco's patented Canti-Leverage AdvantageSM technology. ENSCO 140 and ENSCO 141 were delivered during 2016. Both rigs are expected to obtain drilling contracts for work commencing during 2018. As part of our agreement with Lamprell, these rigs will be warm stacked in the shipyard at no additional cost to us for up to two years from their respective delivery dates.

We previously entered into agreements with Keppel FELS ("KFELS") to construct four ultra-premium harsh environment jackup rigs (ENSCO 120, ENSCO 121, ENSCO 122 and ENSCO 123) and a premium jackup rig (ENSCO 110). ENSCO 120 and ENSCO 121 were delivered during 2013 and ENSCO 122 and ENSCO 110 were delivered during 2014 and 2015, respectively. During 2016, we agreed with the shipyard to delay delivery of ENSCO 123 until


the first quarter of 2018. In December 2017, we agreed to further delay delivery of ENSCO 123 until the first quarter of 2019, and in January 2018, we paid $207.4 million of the $218.3 million unpaid balance with the remainder due upon delivery. ENSCO 123 is currently uncontracted and is actively being marketed.

Divestitures

Our business strategy has been to focus on ultra-deepwater floater and premium jackup operations and de-emphasize other assets and operations that are not part of our long-term strategic plan or that no longer meet our standards for economic returns. Consistent with this strategy, we sold nine jackup rigs, three dynamically positioned semisubmersible rigs, two moored semisubmersible rigs and two drillships during the three-year period ended December 31, 2017. We are marketing for sale ENSCO 7500, which was classified as held-for-sale in our consolidated financial statements as of December 31, 2017.

Following the Merger, we continue to focus on our fleet management strategy in light of the new composition of our rig fleet and are reviewing our fleet composition as we continue positioning Ensco for the future. As part of this strategy, we may act opportunistically from time to time to monetize assets to enhance shareholder value and improve our liquidity profile, in addition to selling or disposing of older, lower-specification or non-core rigs.

BUSINESS ENVIRONMENT


Floaters


In recent years, the more constructive oil price environment has led to an improvement in contracting and tendering activity for floaters. The number of contracted benign environment floaters has increased to 123 at December 31, 2023 from a low of 101 in early 2021, contributing to a 12% increase in global utilization, from 73% to 85%, for the industry's active fleet over the same period. This increase in activity is particularly evident for 6th and 7th generation drillships, such as those included in our floater contractingfleet. Utilization for the global active 6th and 7th generation drillship fleet is currently at 92% and has, on average, exceeded 90% for more than twelve months, resulting in a meaningful improvement in day rates for this class of assets.

In 2022, we completed the reactivation of three stacked drillships and one stacked semisubmersible which have commenced long-term contracts. In 2023, we completed the reactivation of another two previously stacked drillships, VALARIS DS-8 and VALARIS DS-17, for contracts which commenced in the second half of 2023 for work offshore Brazil, and we are currently reactivating another stacked drillship VALARIS DS-7, for a long-term contract offshore West Africa expected to commence in mid-2024.

From a supply perspective, as of December 31, 2023, the number of benign environment continuesfloaters including stacked rigs declined by 42% to be challenged by reduced164 from a peak of 281 in late 2014. Across the stacked drillship fleet and newbuild drillships remaining at South Korean shipyards, we believe there are only ten uncontracted drillships remaining that are likely reactivation candidates over the next few years, including VALARIS DS-11 and the Newbuild Drillships. We anticipate that continued floater demand as well as excess supply. Floater demandgrowth will further reduce available drillship capacity. Also, given the expected high construction cost and lack of shipyard capacity, we do not believe that market conditions are supportive of newbuild construction for the foreseeable future.

Jackups

Contracting and tendering activity for jackups has declined significantlyimproved in recent years due to lower commodity prices which have caused our customers to reduce capital expenditures, resulting in the cancellation and delay of drilling programs. During 2017, we began to see increased activity that is translating into near-term utilization; however, further improvements in demand and/or reductions in supply will be necessary before meaningful increases in day rates are realized.
During 2017, we executed contracts for ENSCO DS-4 and ENSCO DS-10 for two-year and one-year terms, respectively. The contracts contain a one-year priced option for ENSCO DS-4 and five one-year priced options for ENSCO DS-10. ENSCO DS-4 began drilling operations offshore Nigeria in August 2017. Asas a result of the ENSCO DS-10 contract award,more constructive oil price environment and we accelerated deliveryhave seen a corresponding increase in utilization. The number of contracted jackups has increased to September 2017409 at December 31, 2023 from a low of 341 in early 2021, contributing to a 16% increase in global utilization, from 78% to 94%, for the industry's active fleet over the same period, which has led to a meaningful increase in day rates for jackups. In early 2024, Saudi Arabia announced that they plan to maintain maximum sustainable capacity at 12 million barrels per day rather than pursuing their previously stated aim of increasing capacity to 13 million barrels per day. At this early stage, we are unable to predict what, if any, impact this announcement will have on the jackup market or the operations of ARO.

From a supply perspective, as of December 31, 2023, the number of jackups declined by 8% to 498 from a peak of 542 in early 2015. While the number of jackups has decreased less than floaters on a relative basis, 33% of the current jackup fleet is more than 30 years of age with limited useful lives remaining. Further, we believe that some of the jackups that are currently idle are not competitive, either due to their age or length of time stacked. Expenditures required to recertify some of these rigs may prove cost prohibitive and made the final milestone paymentdrilling contractors may instead elect to scrap a portion of $75.0 million,these rigs. Excluding ARO's newbuild program, there are only 17 newbuild jackups remaining at shipyards, of which was previously deferred into 2019. We expect ENSCO DS-10 to commence drilling operations offshore Nigeria in March 2018.

During 2017, we also executed a six-well contract for ENSCO DS-7 and a five-well contract for ENSCO 8504,12 are at Chinese shipyards, many of which are expected to commence in March 2018 in the Mediterranean Sea and Vietnam, respectively. The ENSCO DS-7 contract contains two two-well priced options and the ENSCO 8504 contract contains an option for one well or eight top-hole sections. Additionally, we executed a one-well extension for ENSCO DS-12 (formerly Atwood Achiever) and executed new one-well contracts for ENSCO 8503 and ENSCO 8505.



Jackups

Demand for jackups has improved with increased tendering activity observed during 2017 following historic lows; however, day rates remain depressed due to the oversupply of rigs.

During 2017, we executed a four-year contract for ENSCO 92, three-year contracts for ENSCO 110 and ENSCO 120, a 400-day contract for ENSCO 102 and a one-year contract extension for ENSCO 67. Additionally, we entered into several short-term contracts and contract extensions for ENSCO 68, ENSCO 72, ENSCO 75, ENSCO 87, ENSCO 101, ENSCO 107, ENSCO 115 (formerly Atwood Orca), ENSCO 121 and ENSCO 122.
We also received notices of termination for conveniencebe used for the ENSCO 104 and ENSCO 71 contracts effectivelocal supply in May and August 2017, respectively, which were previously expected to end in January and July 2018, respectively. In January 2018, ENSCO 104 was re-contracted under a 485-day contract.China.

In addition, we sold five jackups for scrap value resulting in insignificant pre-tax gains.

During 2017, excluding the impact of ENSCO DS-9 and ENSCO 8503 lump-sum termination payments totaling $205.0 million received during 2016, revenues declined by $728.4 million, or 28%, asOverview

Revenues increased in 2023, compared to the prior year. The decline was2022, primarily due to fewer floateran increase in average daily revenue earned of $177.6 million primarily attributable to certain rigs that commenced new contracts during 2023 at a higher average daily revenue, $47.7 million from an increase in operating days under contract, lower average dayprimarily attributable to floaters that have commenced contracts following reactivation and $12.5 million of higher revenues earned from lease agreements with ARO primarily from higher lease rates across our fleet and the sale of ENSCO 6004, ENSCO 6003, ENSCO 53 and ENSCO 52. The decline in revenues wasfor certain rigs. These increases were partially offset by a $51.0 million fee recognized for the commencementearly termination of ENSCO DS-4 drilling operations and the addition of Atwood rigs to the fleet during the fourth quarter.VALARIS DS-11 contract in 2022.

Contract drilling expense declined by $111.5 million, or 9%, asincreased in 2023, compared to the prior year2022, primarily due to rig stackings, sale of ENSCO 6004, ENSCO 6003, ENSCO 94, ENSCO 53, ENSCO 52$123.0 million attributable to rigs that have commenced contracts following reactivation, a $43.1 million increase in repair costs for certain rigs and ENSCO 56 and cost control initiatives that reduced personnel costs and other daily rig operating expenses. This decline wasa $36.2 million increase in reactivation costs. These increases were partially offset by rig reactivationa $35.9 million decrease in the costs for certain claims and a $16.1 million decrease in operating costs for VALARIS 140 and VALARIS 141, which we started leasing to ARO at the commencementend of ENSCO DS-4 drilling operationsthe first quarter and the additionthird quarter of Atwood rigs2022, respectively.

During 2022, we recorded non-cash losses on impairment totaling $34.5 million with respect to customer-specific capital upgrades for VALARIS DS-11 made pursuant to the fleet.



During 2016, excludingterms of the impact of ENSCO DS-9 and ENSCO 8503 lump-sum termination payments totaling $205.0 million receiveddrilling contract that was terminated during the yearsecond quarter of 2022. See "Note 7 - Property and ENSCO DS-4Equipment" to our consolidated financial statements included in "Item 8. Financial Statements and ENSCO DS-9 lump-sum termination payments totaling $129.0 million received during 2015, revenues declined by $1.4 billion, or 35%, asSupplementary Data" for additional information.

Depreciation expense increased in 2023, compared to the prior year. The decline was2022, primarily due to fewer days under contract across our fleet, lower average day rates, sale of ENSCO 6003, ENSCO 6004 and ENSCO DS-1, and lower revenues from ENSCO DS-5. The declinenew assets placed in revenues was partially offset by the commencement of ENSCO DS-8 drilling operations and revenue generated from semisubmersibleservice for certain rigs that were undergoing shipyardunderwent reactivation projects during 2015.and capital upgrades.


Contract drilling expense declined by $568.6 million, or 30%, as compared to the prior year primarily due to rig stackings and other cost control initiatives that reduced personnel costs and other daily rig operating expenses as well as the sale of ENSCO 6003, ENSCO 6004 and ENSCO DS-1. This decline was partially offset by ENSCO DS-8 contract drilling expense.

During 2017, we recognized a pre-tax, non-cash loss on impairment of $182.9 million related to certain older, less capable, non-core assets in our fleet. During the fourth quarter, we determined that the remaining useful life of certain non-core rigs would not extend substantially beyond their current contracts resulting in triggering events and the performance of recoverability tests. Our estimates of undiscounted cash flows over the revised estimated remaining useful lives were not sufficient to cover each asset’s carrying value. Accordingly, we concluded that two semisubmersibles and one jackup were impaired as of December 31, 2017.

During 2015, we recognized a pre-tax, non-cash loss on impairment of $2.6 billion, of which $2.5 billion was included in income (loss) from continuing operations and $148.6 million was included in income (loss) from discontinued operations, net, in our consolidated statement of operations. The impairments recognized during 2015 resulted from adverse changes in our business climate that led to the conclusion that triggering events had occurred across our fleet.
During 2017, excluding the impact of $51.6 million of acquisition and integration costs associated with the Merger, generalGeneral and administrative expenses increased by $5.4 million, or 5%, as compared to 2016 primarily due to increasedhigher compensation costs for certain performance-based awards. Generalrelated to our long-term incentive plans and administrative expenses declined by $17.6 million, or 15%,higher professional fees.

Other income, net, decreased in 2016 as2023, compared to 20152022, primarily due to a $112.6 million lower shore-based headcount levels and various other cost control initiatives.

Other income (expense), net, included an estimated gain on bargain purchasethe sale of assets, a $23.6 million increase in interest expense, a $15.7 million decrease in foreign currency gains, and a $15.5 million decrease in net periodic pension and retiree medical income. The decrease is further attributable to a $29.2 million loss on the extinguishment of our First Lien Notes recognized in connection with the Merger of $140.22023. These decreases were partially offset by a $35.9 million during 2017 and pre-tax gains and losses on debt extinguishment totaling $287.8 million and $33.5 million during 2016 and 2015, respectively.increase in interest income.

Rig utilization is derivedoperating days by dividing the number of days under contract by the number of days in the period. Days under contract equals the total number of days that rigs have earned and recognized day rate revenue, including days associated with early contract terminations, compensated downtime and mobilizations. When revenue is earned but is deferred and amortized over a future period, for example when a rig earns revenue while mobilizing to commence a new contract or while being upgraded in a shipyard, the related days are excluded from days under contract.

For newly-constructed or acquired rigs, the number of days in the period begins upon commencementfor the total fleet and active fleet, respectively. Active fleet represents rigs that are not preservation stacked and includes rigs that are in the process of being reactivated. Operating days equals the total number of days that rigs have earned and recognized day rate revenue, including days associated with early contract terminations, compensated downtime and mobilizations and excluding suspension periods. When revenue is deferred and amortized over a future period, for example, when we receive fees while mobilizing to commence a new contract or while being upgraded in a shipyard, the related days are excluded from operating days.

(2)Includes our two management services contracts and our rigs leased to ARO under bareboat charter contracts.

(3)Average daily revenue is derived by dividing contract drilling revenues, adjusted to exclude certain types of non-recurring reimbursable revenues, revenues earned during suspension periods and revenues attributable to amortization of drilling operations for rigs withcontract intangibles, by the aggregate number of operating days. Beginning in 2023, we began presenting average daily revenue instead of the previously reported average day rate metric, which further excluded lump-sum revenues and amortization thereof. Average daily revenue is a contract or when the rig becomes available for drilling operations for rigs without a contract.

Floaters


During 2017, excluding the impact of ENSCO DS-9 and ENSCO 8503 lump-sum termination payments totaling $205.0 million received during 2016, revenues declined by $422.6Floater revenue increased $248.2 million, or 27%. The decline was35%, in 2023 as compared to 2022, primarily due to fewer$210.3 million from increased operating days under contract across our fleet, saleprimarily attributable to rigs that have commenced contracts following reactivation or returned to work upon completion of ENSCO 6003special periodic surveys and ENSCO 6004 and lower$96.7 million from higher average day rates. The decline in revenues was partially offset by the commencement of ENSCO DS-4 drilling operations and the addition of Atwood rigs to the fleet.

Contract drilling expense declined by $100.8 million, or 14%, as compared to the prior yeardaily revenue earned primarily due to rig stackings, sale of ENSCO 6004VALARIS DS-12 and ENSCO 6003 and other cost control initiatives that reduced personnel costs and other daily rig operating expenses. This decline was partially offset by the addition of Atwood rigs to the fleet, rig reactivation costs and ENSCO DS-4 contract drilling expense.

We recognized a loss on impairment of $174.7 million related to two older, less capable, non-core assetsVALARIS DPS-5 working under higher day rate contracts in our fleet whereas we did not recognize any impairment in our floater segment in the prior year period.

Depreciation expense declined by $6.7 million, or 2%, compared to the prior year primarily due to the extension of useful lives for certain contracted rigs, partially offset by the addition of Atwood rigs.

During 2016, excluding the impact of ENSCO DS-9 and ENSCO 8503 lump-sum termination payments totaling $205.0 million received during the year and ENSCO DS-4 and ENSCO DS-9 lump-sum termination payments totaling $129.0 million received during 2015, revenues declined by $770.9 million, or 33%, primarily due to fewer days under contract across the fleet, lower average day rates and the sale of ENSCO 6003, ENSCO 6004 and ENSCO DS-1. This decline was partially offset by the commencement of ENSCO DS-8 drilling operations and revenue generated from rigs that were undergoing shipyard projects during 2015.

Contract drilling expense declined by $327.8 million, or 31%, as compared to the prior year primarily due to rig stackings and other cost control initiatives that reduced personnel costs and other daily rig operating expenses as well as the sale of ENSCO 6003, ENSCO 6004 and ENSCO DS-1. This decline was partially offset by ENSCO DS-8 contract drilling expense.

Depreciation expense declined by $78.3 million, or 20%, primarily due to lower depreciation expense on floaters that were impaired during 2015, partially offset by the addition of ENSCO DS-8 to the active fleet.
Jackups

During 2017, revenues declined by $289.2 million, or 31%,2023 as compared to the prior year. The decline wasThese increases were partially offset by $51.0 million of revenue recognized in 2022 attributable to a termination fee for the VALARIS DS-11 contract.

Floater contract drilling expense increased $166.0 million, or 26%, in 2023 as compared to 2022, primarily due to lower average day rates, fewer days under contract across our fleet, additional shipyard days$167.8 million attributable to rigs that have returned to work upon completion of reactivation projects and sale of ENSCO 53 and ENSCO 52.

Contract drilling expense declined by $4.7an $36.2 million or 1%, as compared to the prior year due to the sale of ENSCO 94, ENSCO 53, ENSCO 52 and ENSCO 56 and other cost control initiatives that reduced personnel costs and other daily rig operating expenses. This decline wasincrease in reactivation costs. These increases were partially offset by rigs that were stackeda $28.4 million decrease in 2016 and operated 2017 and related rig reactivation costs.costs for certain claims.


We recognized a lossDuring 2022, we recorded non-cash losses on impairment of $8.2totaling $34.5 million, relatedwith respect to one older, less capable, non-core asset in our fleet whereas we did not recognize any impairment in our jackup segment in the prior year period.

Depreciation expense increased by $7.8 million, or 6%, as comparedcustomer-specific capital upgrades for VALARIS DS-11 made pursuant to the prior year primarily due toterms of the additiondrilling contract that was terminated during the second quarter of Atwood rigs, partially offset by the extension of useful lives for certain contracted rigs.



During 2016, revenues declined by $516.1 million, or 36%, as compared to the prior year. The decline in revenues was primarily due to lower average day rates2022. See "Note 7 -Property and fewer days under contract across our fleet.

Contract drilling expense declined by $176.7 million, or 25%, as compared to the prior year due to rig stackings and other cost control initiatives that reduced personnel costs and other daily rig operating expenses. This decline was partially offset by deferred gain amortization on the sale of ENSCO 83, ENSCO 89 and ENSCO 98 during 2015.

Depreciation expense declined by $52.0 million, or 30%, as compared to the prior year primarily due to lower depreciation expense on jackups that were impaired during 2015. The decline was partially offset by the addition of ENSCO 110 to the active fleet.
Impairment of Long-Lived Assets and Goodwill

See Note 4 and Note 9Equipment" to our consolidated financial statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.

Floater depreciation expense increased $5.8 million, or 12%, in 2023 as compared to 2022, primarily due to new assets placed in service for certain rigs that underwent reactivation projects and capital upgrades.

Jackups

Jackup revenues declined $84.6 million, or 11%, in 2023 as compared to 2022, primarily due to $162.6 million from decreased operating days primarily due to rigs that completed contracts in the North Sea during the first half of 2023 due to lower activity in the region, certain rigs that were mobilizing or idle between contracts during 2023, and the sale of VALARIS 54 which operated in 2022. These decreases were partially offset by a $75.2 million increase due to higher average daily revenue earned.

Jackup contract drilling expense declined $21.5 million, or 4%, in 2023 as compared to 2022, primarily due to $49.2 million of lower costs for rigs that were idle or between contracts in 2023, and a $16.1 million decrease in operating costs for VALARIS 140 and VALARIS 141, which we started leasing to ARO in 2022. These decreases were partially offset by a $42.1 million increase in repair costs in 2023 primarily associated with maintenance performed during special periodic surveys.

Jackup depreciation expense increased $3.9 million, or 11%, in 2023 as compared to 2022, due to new assets placed in service for certain rigs that underwent capital upgrades, partially offset by VALARIS 54, which was sold in the second quarter of 2023.

ARO

The operating revenues of ARO reflect revenues earned under drilling contracts with Saudi Aramco for the ARO-owned jackup rigs and the rigs leased from us. Contract drilling expenses are inclusive of the bareboat charter fees for the rigs leased from us. 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 impairmentARO and related arrangements.

56


Revenue increased $37.1 million, or 8%, in 2023 as compared to 2022, primarily due to a $29.2 million increase from VALARIS 140 and VALARIS 141, which were leased to ARO starting in 2022, and from Kingdom 1, a newbuild jackup rig, which commenced operations in the fourth quarter of long-lived assets2023. Furthermore, there was a $24.3 million increase from higher average daily revenue earned by certain rigs. These increases were partially offset by $9.0 million decrease due to VALARIS 36 which operated in the prior year until the rig was sold in May 2022 and goodwill, respectively.$7.8 million for certain rigs undergoing maintenance projects in 2023.

Contract drilling expense increased $24.1 million, or 7%, in 2023 as compared to 2022, primarily due to $13.8 million of incremental operating costs related to VALARIS 140, VALARIS 141 and Kingdom 1, $8.7 million from higher personnel cost and a $4.8 million increase in repair and maintenance costs. These increases were partially offset by $7.5 million decrease from VALARIS 36, which operated in prior year until it was sold in May 2022.

Other

Other revenues increased $18.1 million, or 11%, in 2023 as compared to 2022, primarily due to $12.5 million of higher revenues earned from lease agreements with ARO attributable to higher average daily revenue on certain leased rigs and $5.7 million from higher average daily revenue earned for our management services contracts.

Interest income during 2017 and 2016 increased by $35.9 million, or 55%, in 2023 as compared to 2022, primarily due to an increase of $33.3 million of interest income on cash equivalents due to a higher average balance during 2023 and a $19.2 million increase on interest income earned on our Notes Receivable from ARO attributable to higher interest rates in 2023, partially offset by non-cash interest income of $14.8 million recognized in the respective prior year periodson the partial principal repayment of our Notes Receivable from ARO in September 2022.

Interest expense, net increased by $23.6 million, or 52%, in 2023 as compared to 2022, primarily due to a higher principal debt balance in 2023.

We recognized a $29.2 million loss from the extinguishment of the First Lien Notes in 2023.

Net gains on the sale of property decreased by $112.6 million in 2023 as compared to 2022, primarily due $140.7 million of gains recognized in 2022 on the sales of VALARIS 113, VALARIS 114, VALARIS 36 and VALARIS 67 and additional proceeds received for two rigs sold in prior years as a result of higher average short-term investment balances.

Interest expense during 2017 increased by $22.2 million, or 8%, as compared to the prior year due to the issuancepost-sale conditions of convertible debt and exchange notes, partially offset by lower interest expense due to debt repurchases. Interest expense during 2016 declined by $29.2 million, or 10%, as compared to the prior year due to the reduction of $1.2 billion of debt through repurchases and exchange.

Interest expense capitalized during 2017 increased $26.8 million, or 59%, as compared to the prior year due to an increase in the amount of capital invested in newbuild construction. Interest expense capitalized during 2016 declined $41.7 million, or 48%, as compared to the prior year due to newbuild rigs placed into service during 2015 and 2016.

Our functional currency is the U.S. dollar, and 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. However, we have net assets and liabilities denominated in numerous foreign currencies and a portion of the revenues earned and expenses incurred by certain of our subsidiaries are denominated in currencies other than the U.S. dollar. These transactions are remeasured


in U.S. dollars based on a combination of both current and historical exchange rates.

Accordingly, during periods of declining profitability, our income tax expense may not decline proportionally with income, which could result in higher effective income tax rates. Furthermore, we will continue to incur income tax expense in periods in which we operate at a loss.

Our drilling rigs frequently move from one taxing jurisdiction to another to perform contract drilling services. In some instances, the movement of drilling rigs among taxing jurisdictions will involve the transfer of ownership of the drilling rigs among our subsidiaries. As a result of frequent changes in the taxing jurisdictions in which our drilling rigs are operated and/or owned, changes in profitability levels and changes in tax laws, our annual effective income tax rate may vary substantially from one reporting period to another.

U.S. Tax Reform

The U.S. Tax Cuts and Jobs Act (“U.S. tax reform”) was enacted on December 22, 2017 and introduced significant changes to U.S. income tax law, including a reduction in the statutory income tax rate from 35% to 21% effective January 1, 2018, a base erosion anti-abuse tax that effectively imposes a minimum tax on certain payments to non-U.S. affiliates and new and revised rules relating to the current taxation of certain income of foreign subsidiaries.
We recognized a net tax expense of $16.5 million during the fourth quarter of 2017 in connection with enactment of U.S. tax reform, consisting of2023 to reduce our valuation allowance due to the determination that sufficient positive evidence now exists to conclude that a $38.5 million tax expense associated with the one-time transition tax on deemed repatriationportion of the deferred foreign incomeallowance is no longer needed. During 2023, we also recognized tax benefits for the reduction of unrecognized tax benefit liabilities related to the lapse of statutes of limitations applicable to certain of our U.S. subsidiaries,tax positions of $73.6 million and settlements reached with taxing authorities of $41.8 million. These benefits were partially offset by a $17.3$88.6 million tax expense associated with revisions to rules over the taxation of income of foreign subsidiaries, a $20.0 millionincrease in unrecognized tax benefit resultingliabilities for tax positions taken during prior years, including $66.0 million recognized in the fourth quarter of 2023 related to tax assessments received from the re-measurement of our deferredLuxembourg tax assets and liabilities as of December 31, 2017 to reflect the reduced tax rate and a $19.3 million tax benefit resulting from adjustments to the valuation allowance on deferred tax assets.

Due to the timing of the enactment of U.S. tax reform and the complexity involved in applying its provisions, we have made reasonable estimates of its effects and recorded such amounts in our consolidated financial statements as of December 31, 2017 on a provisional basis. As we continue to analyze applicable information and data, and interpret any additional guidance issued by the U.S. Treasury Department, the Internal Revenue Service and others, we may make adjustments to the provisional amounts throughout the one-year measurement period as provided by Staff Accounting Bulletin No. 118. Our accounting for the enactment of U.S. tax reform will be completed during 2018 and any adjustments we recognize could be material. The ongoing impact of U.S. tax reform may result in an increase in our consolidated effective income tax rate in future periods.authorities.

Effective Tax Rate

During the years ended December 31, 2017, 2016 and 2015, we recorded income tax expense of $109.2 million and $108.5 million and income tax benefit of $13.9 million, respectively. Our consolidated effective income tax rates were (55.7)%, 10.9% and 0.9% during the same periods, respectively.

Our 20172023 consolidated effective income tax rate includes $32.2discrete tax benefit of $42.0 million primarily attributable to changes in liabilities for unrecognized tax benefits associated with tax positions taken in prior years including unrecognized tax benefits described above.

Our 2022 consolidated effective income tax rate includes $10.3 million associated with the impact of various discrete tax items, including $16.5 million of tax expense associated with U.S. tax reform and $15.7 million of tax expense associated with the exchange offers and debt repurchases, rig sales, a restructuring transaction, settlement of a previously disclosed legal contingency, the effective settlement of a liability for unrecognized tax benefits associated with a tax position taken in prior years and other resolutions of prior year tax matters.

Our 2016 consolidated effective income tax rate includes the impact of various discrete tax items, including a $16.9$17.2 million tax expense resulting from net gains on the repurchase of various debt during the year, the recognition of an $8.4 million net tax benefit relating to the sale of various rigs, a $5.5 million tax benefit resulting from a net reduction in the valuation allowance on U.S. foreign tax credits and a net $5.3 millionincome tax benefit associated with changes in liabilities for unrecognized tax benefits and resolution of other adjustments relatingprior period tax matters, offset primarily by tax expense attributable to prior years.

Our consolidated effective income tax rate for 2015 includes the impact of various discrete tax items, primarily related to a $192.5 million tax benefit associated with rig impairments and an $11.0 million tax benefit resulting from the reduction of a valuation allowance on U.S. foreign tax credits.contract termination.


Excluding the impact of the aforementioned discrete tax items, our consolidated effective income tax rates for the years ended December 31, 2017, 20162023 and 20152022 were (96.0)(872.3)%, 20.3% and 16.0%73.6%, respectively. The changes in our consolidated effective income tax rate excluding discrete tax items during the three-year period result primarily from changes in the relative components of our earnings from the various taxing jurisdictions in which our drilling rigs are operated and/or owned and differences in tax rates in such taxing jurisdictions.


Divestitures


Our business strategy has been to focus on ultra-deepwater floater and premium jackup operations and de-emphasize other assets and operations that are not part of our long-term strategic plan or that no longer meet our standards for economic returns. Consistent with this strategy, we sold ninefive jackup rigs three dynamically positioned semisubmersible rigs, two moored semisubmersible rigs and two drillships during the three-yeartwo-year period ended December 31, 2017. We are marketing for sale ENSCO 7500, which was classified as held-for-sale in our consolidated financial statements as of December 31, 2017.2023.


Following the Merger, weWe continue to focus on our fleet management strategy in light of the new composition of our rig fleet and are reviewingfleet. While taking into account certain restrictions on the sales of assets under our fleet compositiondebt agreements, as we continue positioning Ensco for the future. As part of thisour strategy, we may act opportunistically from time to time to monetize assets to enhance shareholderstakeholder value and improve our liquidity profile, in addition to reducing holding costs by selling or disposing of older, lower-specification or non-core rigs.

Discontinued Operations

Prior to 2015, individual rig disposals were classified as discontinued operations once the rigs met the criteria to be classified as held-for-sale. The operating results of the rigs through the date the rig was sold as well as the gain or loss on sale were included in results from discontinued operations, net, in our consolidated statement of operations. Net proceeds from the sales of the rigs were included in investing activities of discontinued operations in our consolidated statement of cash flows in the period in which the proceeds were received.

During 2015, we adopted the Financial Accounting Standards Board’s Accounting Standards Update 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity ("Update 2014-08"). Under the new guidance, only disposals representing a strategic shift in operations should be presented as discontinued operations. As a result, individual assets that are classified as held-for-sale beginning in 2015 are not reported as discontinued operations and their operating results and gain or loss on sale of these rigs are included in contract drilling expensefor each rig in our consolidated statementsConsolidated Statements of operations. Rigs that were classified as held-for-sale prior to 2015 continue to be reported as discontinued operations.Operations.



During 2014, we committed to a plan to sell various non-core floaters and jackups. The operating results for these rigs and any related gain or loss on sale were included in results from discontinued operations, net, in our consolidated statements of operations. ENSCO 7500 continues to be actively marketed for sale and was classified as held-for-sale on our December 31, 2017 consolidated balance sheet.

In September 2014, we sold ENSCO 93, a jackup contracted to Pemex. In connection with this sale, we executed a charter agreement with the purchaser to continue operating the rig for the remainder of the Pemex contract, which ended in July 2015, less than one year from the date of sale. Our management services following the sale did not constitute significant ongoing involvement and therefore, the rig's operating results through the term of the contract and loss on sale were included in results from discontinued operations, net, in our consolidated statements of operations.

On a quarterly basis, we reassess the fair values of our held-for-sale rigs to determine whether any adjustments to the carrying values are necessary.  We recorded a non-cash loss on impairment totaling $120.6 million (net of tax benefits of $28.0 million) for the year ended December 31, 2015 as a result of declines in the estimated fair values of our held-for-sale rigs. The loss on impairment was included in loss from discontinued operations, net, in our consolidated statements of operations for the year ended December 31, 2015. We measured the fair value of held-for-sale rigs by applying a market approach, which was based on an unobservable third-party estimated price that would be received in exchange for the assets in an orderly transaction between market participants.

Income tax benefit from discontinued operations for the year ended December 31, 2017 and 2016 included $2.1 million and $10.2 million of discrete tax benefits, respectively.
Debt and interest expense are not allocated to our discontinued operations.

Based on our balance sheet, our contractual backlog and $2.0 billion available under our revolving credit facility, we expect to fund our short-term and long-term liquidity needs, including contractual obligations and anticipated capital expenditures, dividends and working capital requirements, fromOur cash and cash equivalents short-term investments, operating cash flowsas of December 31, 2023 and if necessary, funds borrowed under our revolving credit facility or other future financing arrangements. During 2017 and in early 2018, we executed several transactions to maximize our liquidity.

In January 2018, we issued $1.0 billion aggregate principal amount of unsecured 7.75% senior notes due 2026 at par, net of debt issuance costs of $16.5 million. Net proceeds of $983.5 million from the 2026 Notes2022, were partially used to fund the repurchase and redemption of $237.6 million principal amount of our 8.50% notes due 2019, $256.6 million principal amount of our 6.875% notes due 2020 and $156.2 million principal amount of our 4.70% notes due 2021. We expect to recognize a pre-tax loss on debt extinguishment of $18.2 million during the first quarter of 2018.

Upon closing of the Merger, we utilized acquired cash of $445.4$620.5 million and cash on hand from the liquidation of short-term investments$724.1 million, respectively. We have no debt principal payments due until 2030 and had $375.0 million available for borrowing, including up to repay Atwood's debt and accrued interest of $1.3 billion. We amended our credit facility upon closing to extend the final maturity date by two years. Previously, our credit facility had a borrowing capacity of $2.25 billion through September 2019 that declined to $1.13 billion through September 2020. Subsequent to the amendment, our borrowing capacity is $2.0 billion through September 2019 and declines to $1.3 billion through September 2020 and to $1.2 billion through September 2022. The credit facility, as amended, requires us to maintain a total debt to total capitalization ratio that is less than or equal to 60%.

In January 2017, through a private-exchange transaction, we repurchased $649.5$150.0 million of our outstanding debt with $332.5 million of cash and $332.0 million of newly issued 8.00% senior notes due 2024. During the remainder of the year, we repurchased $194.1 million aggregate principal amount of our outstanding debt on the open market for $204.5 million of cash and recognized an insignificant pre-tax gain, net of discounts, premiums and debt issuance costs.

During the three-year period ended December 31, 2017, our primary sources of cash were an aggregate $3.0 billion generated from operating activities of continuing operations, $1.9 billion in proceeds from the issuance of senior notesletters of credit, under the Credit Agreement as of February 16, 2024. See "Note 8 - Debt" to our consolidated financial statements included in "Item 8. Financial Statements and $585.5 million in proceeds from an equity offering.

Our primary uses of cash were $337.0 million receivedfor the purchase of the Newbuild Drillships and $359.1 million for maintenance and upgrades of our drilling rigs, including reactivations. Our other primary sources and uses of cash during 2016, cash flows from continuing operations declined by $613.0 million, or 70%, as compared to the prior year.  The decline primarily2023 resulted from the First Lien Note redemption, the corresponding Second Lien Notes issuance and our share repurchase program, which are each further discussed below.

During the year ended December 31, 2022, our other primary sources of cash were proceeds of $150.3 million for the disposition of assets and $40.0 million from the partial early repayment of the Notes Receivable from ARO. For the same period, our cash provided by operating activities of $127.0 million related primarily to improving margins and the collection of $54.8 million for certain tax receivables.

Based on our current projections, we expect capital expenditures during 20182024 to includeapproximate $390.0 million to $430.0 million primarily relating to maintenance and upgrade projects, including rig reactivation and associated contract-specific capital expenditures. We expect to receive upfront payments from our customers of approximately $375 million for newbuild construction, approximately $40 million for rig enhancement projects and approximately $60 million for minor upgrades and improvements. Of the $375 million for newbuild construction, $207.4$55.0 million relating to ENSCO 123 was paid in January 2018.these projects. Depending on market conditions, contracting activity and future opportunities, we may reactivate additional rigs or make additional capital expenditures to upgrade rigs for customer requirements and construct or acquire additional rigs.


Dividends

We review from time to time possible acquisition opportunities relating to our business, which may include the acquisition of rigs or other businesses. The timing, size or success of any acquisition efforts and the associated potential capital commitments are unpredictable and uncertain. We may seek to fund all or part of any such efforts with cash on hand and proceeds from debt and/or equity issuances and may issue equity directly to the sellers. Our Board of Directors declared a $0.01 quarterly cash dividend per Class A ordinary shareability to obtain capital for each quarter during 2017. In October 2017, we amendedadditional projects to implement our revolving credit facility, which prohibits us from paying dividendsgrowth strategy over the longer term will depend on our future operating performance, restrictions to incur additional debt 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. The declarationIndenture and amount of future dividends is at the discretion of our Board of Directors. In the future, our Board of Directors may, without advance notice, determine to reduce or suspend our dividend in order to improve our financial flexibility and best position us for long-term success. When evaluating dividend payment timing and amounts, our Board of Directors considers several factors, including our profitability, liquidity,Credit Agreement, financial condition market outlook, reinvestment opportunities, capitaland, more broadly, on the availability of equity and debt financing. Capital availability will be affected by prevailing conditions in our industry, the global economy, the global financial markets and other factors, many of which are beyond our control. In addition, any additional debt service requirements we take on could be based on higher interest rates and limitations undershorter maturities and could impose a significant burden on our revolving credit facility.results of operations and financial condition, and the issuance of additional equity securities could result in significant dilution to shareholders.



In connection with our sustainability-related efforts, during 2023, we spent approximately $7.0 million and expect spend during 2024 to be comparable. Our sustainability initiatives will continue to require, among other actions, investment in systems and equipment and coordination with our customers.

The First Lien Notes were redeemed on May 3, 2023 for an aggregate redemption price of approximately $571.8 million (excluding accrued and total debt to total capital ratios asunpaid interest) with a portion of December 31, 2017, 2016 and 2015 are summarized below (in millions, except percentages):

In January 2018, total debt increased by $306.8 million as a result of the issuance of $1.0 billion of 7.75% senior notes due 2026 issued net of debt issuance costs of $16.5 million, partially offset by the debt repurchases and redemptions of our 8.5% senior notes due 2019, 6.875% senior notes due 2020 and 4.70% senior notes due 2021, which had an aggregate carrying value of $676.7 million, net of discounts, premiums and issuance costs. Total capital was adjusted by the aforementioned amount and the estimated net of tax loss on the repurchases and redemptions of $14.8 million.

Total capital consists of total debt and Ensco shareholders' equity.

During 2017, our total debt and total capital declined by $523.8 million and $42.3 million, respectively. This resulted in the decline of our total debt to total capital rationet proceeds from 39.0% to 35.2% due to debt repurchases, a loss on impairment and the equity issued and bargain purchase gain recognized in connection with the Merger.

During 2016, our total debt declined by $594.1 million and our total capital increased by $1.1 billion. This resulted in the decline of our total debt to total capital ratio from 47.4% to 39.0% primarily due to debt repurchases and exchanges, the issuance of the Initial Second Lien Notes, as discussed below.

Revolving Credit

In October 2017, we amended our revolving credit facility ("Credit Facility") to extend the final maturity date by two years. Previously, our Credit Facility had a borrowing capacity of $2.25 billion through September 2019 that declined to $1.13 billion through September 2020. Subsequent to the amendment, our borrowing capacity is $2.0 billion through September 2019 and declines to $1.3 billion through September 2020 and to $1.2 billion through September 2022. The credit agreement governing our revolving credit facility includes an accordion feature allowing us to increase the commitments expiring in September 2022 up to an aggregate amount not to exceed $1.5 billion.

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 $2.0 billion commitment, which is also based on our credit ratings.

In October 2017, Moody's announced a downgrade of our credit ratingNotes Receivable from B1 to B2, and Standard & Poor's downgraded our credit rating from BB to B+, which are both ratings below investment grade. In January 2018, Moody's downgraded our senior unsecured bond credit rating from B2 to B3. The Credit Facility amendment and the rating actions resulted in increases to the interest rates applicable to our borrowings and the quarterly commitment fee on the undrawn portion of the $2.0 billion commitment. The applicable margin rates are 3.00% per annum for Base Rate advances and 4.00% per annum for LIBOR advances. The quarterly commitment fee is 0.75% per annum on the undrawn portion of the $2.0 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 $750 million 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 continue paying 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 $150 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, 2017, 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 2018. We had no amounts outstanding under the Credit FacilityARO as of December 31, 2017and 2016.2023 (in millions):

Maturity DatePrincipal Amount

Total$402.7 
Our access to credit and capital markets depends on the credit ratings assigned to our debt. As a result of rating actions by these agencies, we no longer maintain an investment-grade status. Our current credit ratings, and any additional actual or anticipated downgrades in our credit ratings, could limit our available options when accessing credit and capital markets, or when restructuring or refinancing our debt. In addition, future financings or refinancings may result in higher borrowing costs and require more restrictive terms and covenants, which may further restrict our operations.
Other Financing

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 2013, our shareholders approved a new share repurchase program. Subject to certain provisions under English law, including the requirement of Ensco plc to have sufficient distributable reserves, we may repurchase shares up to a maximum of $2.0 billion in the aggregate under the program, but in no case more than 35.0 million shares. As of September 30, 2017, no shares have been repurchased under the program. The program terminates in May 2018. In October 2017, we amended our revolving credit facility, which 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 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. There can be no assurance that an active trading market will exist for our outstanding senior notes following any such transaction.



Contractual Obligations


We have various contractual commitments related to our new rig construction and rig enhancement agreements, long-term debt and operating leases. We expect to fund these commitments from existing cash and short-term investments, future operating cash flows, borrowings under our revolving credit facility or other future financing arrangements.  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.  The following table summarizes our significant contractual obligations as of December 31, 20172023 and the periods in which such obligations are due (in millions):

In connection with our 50/50 unconsolidated joint venture, we have a potential obligation to fund ARO for newbuild jackup rigs. The Shareholder Agreement specifies that ARO shall purchase 20 newbuild jackup rigs over an approximate 10-year period. In January 2020, ARO ordered the first two newbuild jackups and paid 25% of the purchase price from cash on hand. The first rig, Kingdom 1, was delivered in the fourth quarter 2023, and the second is expected to be delivered in the first half of 2024. In October 2023, ARO entered into a $359.0 million term loan to finance the remaining newbuild payments due upon delivery and for general corporate purposes. The term loan matures in eight years following the related drawdown under the term loan and requires equal quarterly amortization payments during the term, with a 50% balloon payment due at maturity. The term loan bears interest based on the three-month Secured Overnight Financing Rate (SOFR) plus a margin ranging from 1.25% to 1.4%. Our Notes Receivable from ARO are subordinated and junior in right of payment to ARO’s term loan.

ARO is expected to commit to orders for two additional newbuild jackups in the near term and intends for these newly ordered jackup rigs to be financed out of cash on hand or from operations or funds available from third-party financing. In the event ARO has insufficient cash 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. Beginning with the delivery of the second newbuild, each partner's commitment shall be reduced by the lesser of the actual cost of each newbuild rig or $250.0 million, on a proportionate basis. 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.

Obligations under these letters of credit are not normally called, as we typically comply with the underlying performance requirement. As of December 31, 2017,2023, we had not been required to make collateral deposits in the amount of $12.6 million with respect to these agreements.

Tax Assessments


Liquidity
Our liquidity positionIn February 2024, one of our Malaysian subsidiaries received an unfavorable court decision regarding a tax assessment for the 2012-2017 tax years totaling approximately MYR 117.0 (approximately $26.0 million converted at current period-end exchange rates), including a late payment penalty. Based on this development, we may be required to pay the full amount to further contest the assessment. We have not recorded a liability for uncertain tax positions as of December 31, 2017, 20162023, related to this assessment based on a more-likely-than-not threshold. We believe our tax returns are materially correct as filed, and 2015will vigorously contest this assessment.

In December 2023, one of our Luxembourg subsidiaries received tax assessments for fiscal years 2019, 2020, 2021 and 2023 and a demand of payment from the Luxembourg tax authorities for an aggregate of approximately €115.0 million (approximately $127.0 million converted at current period-end exchange rates), including interest. In February 2024, we subsequently received notice from the Luxembourg tax authorities reducing the amount attributable to the 2023 payment demand by approximately €55.0 million resulting in a revised aggregate tax demand of approximately €60.0 million. We have recorded a liability for uncertain tax positions of approximately €60.0 million (approximately $66.0 million converted at current period-end exchange rates) in the fourth quarter of 2023 related to the assessments for the 2019-2021 tax years. We are vigorously contesting these assessments, including the validity and amount; however, the outcome of such challenges and related administrative proceedings and appeals cannot be predicted with certainty. An unfavorable outcome could result in a material impact on our financial position, operating results and cash flows.

During 2019, the Australian tax authorities issued aggregate tax assessments totaling approximately A$101.0 million (approximately $69.0 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$42.0 million payment (approximately $29.0 million at then-current exchange rates) to the Australian tax authorities to litigate the assessment. We have an $18.8 million liability for uncertain tax positions relating to these assessments as of December 31, 2023. 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.

See "Note 12 - Income Taxes" to our consolidated financial statements included in "Item 8. Financial Statements and Supplementary Data" for additional information on these tax assessments.

Share Repurchase Program

In 2022, our board of directors authorized a share repurchase program under which we may purchase up to $100.0 million of our outstanding Common Shares. In April 2023, the board of directors authorized an increase of this amount to $300.0 million and in February 2024, they authorized a further increase to $600.0 million. The share repurchase program does not have a fixed expiration, may be modified, suspended or discontinued at any time and is summarized below (in millions, except ratios):

Pro Forma balances represent our cash and cash equivalents, short-term investments, working capital and current ratio after giving effect to the January 2018 debt issuance and tender offers described above. Our cash and cash equivalents balance increased by $276.2 million due to the proceeds from the issuance of $1.0 billion of 7.75% senior notes due 2026, net of $16.5 million of issuance costs, partially offset by $707.3 million cash paid for repurchases and redemptions of our 8.5% senior notes due 2019, 6.875% senior notes due 2020 and 4.70% senior notes due 2021, inclusive of accrued interest and commissions. Our working capital balance increased by the aforementioned net cash proceeds and related reduction in accrued interest.

We expectsubject to fundcompliance with applicable covenants and restrictions under our short-term liquidity needs,financing agreements. Common Shares may be repurchased under the repurchase program in open market purchases, private-negotiated purchases, through block trades, by effecting a tender offer, by way of accelerated share repurchase transactions or other derivative transactions, through the purchase of call options or the sale of put options, or otherwise, or by any combination of the foregoing. The manner, timing, pricing and amount of any repurchases are subject to our discretion and may be based upon a number of factors, including contractual obligations and anticipated capital expenditures, as well as dividends and workingmarket conditions, our earnings, capital requirements, from ourfinancial conditions, available cash resources and competing uses for cash equivalents, short-term investments, operating cash flows and, if necessary, funds borrowed under our revolving credit facility.that may arise in the future, debt agreement restrictions other factors. During the year ended December 31, 2023, we repurchased 3.0 million shares at an aggregate cost of $200.0 million, exclusive of fees incurred, at an average price of $66.77.


We expect to fund our long-term liquidity needs, including contractual obligations, anticipated capital expenditures and dividends, from our operating cash flows and, if necessary, funds borrowed under our revolving credit facility or other future financing arrangements. We may decide to access debt and/or equity markets to raise additional capital or increase liquidity as necessary.

Notwithstanding our current liquidity position, if we experience significant further deterioration in demand for offshore drilling, our ability to maintain a sufficient level of liquidity to meet our financial obligations could be materially and adversely impacted. Further, our access to credit and capital markets depends on the credit ratings assigned to our debt by independent credit rating agencies. Our credit rating is no longer investment-grade. Our current credit ratings, and any additional actual or anticipated downgrades in our credit ratings, could limit our ability to access credit and capital markets, or to restructure or refinance our indebtedness. In addition, future financings or refinancings may result in higher borrowing costs and require more restrictive terms and covenants, which may further restrict our operations.



Effects of Climate Change and Climate Change Regulation
 
Greenhouse gas ("GHG")GHG emissions have increasingly become the subject of international, national, regional, state and local attention. At the December 2015 Conference of the Parties to theThe United Nations Framework Convention on Climate Change ("UNFCC") held in Paris, an agreement was reached that requires countries to review and "represent a progression" in their intended nationally determined contributions to the reduction of GHG emissions, setting GHG emission reduction goals every five years beginning in 2020. This agreement, known asStates reentered the Paris Agreement entered into force onin February 2021. Further, in November 4, 2016 and, as of late 2017, had been ratified by 173 of the 197 parties to the UNFCC, including the United Kingdom,2021, the United States and other countries entered into the majorityGlasgow Climate Pact, which includes a range of measures designed to address climate change, including but not limited to the phase-out of fossil fuel subsidies, reducing methane emissions 30% by 2030, and cooperating toward the advancement of the development of clean energy. It is expected that new executive orders, regulatory action, and/or legislation targeting GHG emissions, or prohibiting, restricting, or delaying oil and gas development activities in certain areas, will be proposed and/or promulgated. For example, 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 (“EO 13990”) and (2) Executive Order on Tackling the Climate Crisis at Home and Abroad (“EO 14008”). EO 13990 established an interagency working group to recommend methods for agencies to incorporate the “social cost of carbon” into regulatory analyses and directed the EPA to review various environmental regulations for consistency with the policies and goals set forth in EO 13990. EO 14008 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 GHG emissions by or before mid-century is a critical priority. Ongoing legal challenges have slowed or halted the implementation of such executive orders, and the full impact of these federal actions, or any other countries in which we operate. However, on August 4, 2017, the United States formally communicated to the United Nations its intent to withdraw from participation in the Paris Agreement, which entails a four year process. 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.future restrictions or prohibitions, remains unclear.

In an effort to reduce GHG emissions, governments have put in placeimplemented 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. The Companies Act 2006 (StrategicGovernments have also proposed or implemented new or enhanced disclosure requirements related to climate change matters and Directors' Reports) Regulations 2013 now requires all quoted U.K. companies, including Ensco plc, to report their annual GHG emissions inthat may increase compliance and disclosure costs, such as the Company's directors' report.SEC’s 2022 proposed rules for a climate change reporting framework.


65


During 2009, the United States Environmental Protection Agency (the "EPA")EPA officially published its findings that emissions of carbon dioxide, methane and other GHGs present an endangerment to human health and the environment because emissions of such gases are, according to the EPA, contributing to warming of the earth'searth’s atmosphere and other climatic changes. These EPA findings allowed the agency to proceed with the adoption and implementation of regulations to restrict GHG emissions under existing provisions of the Clean Air Act that establish Prevention of Significant Deterioration ("PSD") construction and Title V operating permit reviewspermitting requirements, including emissions control technology requirements, for certain large stationary sources that are potential major sources of GHG emissions. Facilities required to obtain PSD permits for their GHG emissions are required to meet "best available control technology" standards established by the states or, in some cases, the EPA, on a case-by-case basis. The EPA has also adopted rules requiring annual monitoring and reporting of GHG emissions from specified sources in the United States,U.S., including, among others, certain onshore and offshore oil and natural gas production facilities. Although a number of bills related to climate change have been introduced in the U.S. Congress in the past, it appears unlikely that comprehensive federal climate legislation will behas not yet been passed by Congress in the foreseeable future.Congress. If such legislation were to be adopted in the United States,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.programs and commitments to contribute to meeting the goals of the Paris Agreement.


Future legislation or 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. Depending on the particular program, we, or our customers, could be required to control GHG emissions or to purchase and surrender allowances for GHG emissions resulting from our operations. It is uncertain whether any of these initiatives will be implemented. If such initiatives are implemented we do not believe thatand what the impact of such initiatives would have a direct, material adverse effect on our financial condition, operating results and cash flows in a manner different than our competitors.flows.


Restrictions on GHG emissions or other related legislative or regulatory enactments could have an indirect effect in those industries that use significant amounts of petroleum products, which could potentially result in a reduction in demand for petroleum products and, consequently, our offshore contract drilling services. We are currently unable to predict the manner or extent of any such effect. Furthermore, one of the long-term physical effects of climate change may be an increase in the severity and frequency of adverse weather conditions, such as hurricanes, which may increase our insurance costs or risk retention, limit insurance availability or reduce the areas in which, or the number of days during which, our customers would contract for our drilling rigs in general and in the Gulf of Mexico in particular. We are currently unable to predict the manner or extent of any such effect.



MARKET RISK

Interest Rate Risk

Our outstanding debt at December 31, 2023 consisted of our $1.1 billion aggregate principal amount of Second Lien Notes. We use derivativesare subject to reduceinterest rate risk on our exposurefixed-interest rate borrowings. Fixed rate debt, where the interest rate is fixed over the life of the instrument, exposes us to foreign currency exchangechanges in market interest rates impacting the fair value of the debt.

Our Credit Agreement provides for commitments permitting borrowings of up to $375.0 million at December 31, 2023. As the interest rates for such borrowings are at variable rates, we are subject to interest rate risk. However, as of December 31, 2023, we had no outstanding borrowings under the Credit Agreement.

Our Notes Receivable from ARO historically accrued interest based on a one-year LIBOR rate. Effective December 2023, the Notes Receivable from ARO bear interest based on the one-year term SOFR rate, set as of the end of the year prior to the year applicable, plus 2.10%. As the Notes Receivable from ARO bear interest on the applicable SOFR rate determined at the end of the preceding year, the rate governing our interest income in 2024 has already been determined. A hypothetical 1% decrease to SOFR would decrease interest income for the year ended December 31, 2024 by $4.0 million based on the principal amount outstanding at December 31, 2023 of $402.7 million.

Foreign Currency Risk

Our functional currency is the U.S. dollar. As is customary in the oil and gas industry, a majority of our revenues and expenses are denominated in U.S. dollars; however, a portion of the revenues earned and expenses incurred by certain of our subsidiaries are denominated in currencies other than the U.S. dollar. 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 exposureare exposed 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 reducesto the portionextent the amount of our cash flows andmonetary assets denominated in foreign currencies. As of December 31, 2017, we had cash flow hedges outstanding to exchange an aggregate $188.4 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 inthe foreign currency exchange rates. We occasionally enter into derivatives that hedgediffers from our obligations in the fair value of recognized foreign currency denominated assets or liabilities, thereby reducing exposure to earnings fluctuations caused by changesrevenue earned differs from costs incurred in the foreign currency exchange rates.currency. 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 fair value of the underlying hedged items. As of December 31, 2017, we held derivatives not designated as hedging instruments to exchange an aggregate $131.1 million for various foreign currencies.
If we were to incur a hypothetical 10% adverse change in foreign currency exchange rates, net unrealized losses associated withcurrently hedge our foreign currency denominated assets and liabilities as of December 31, 2017 would approximate $13.1 million. Approximately $13.1 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.risk.


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.
66


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. See Note 6 to our consolidated financial statements included in "Item 8. Financial Statements and Supplementary Data" for additional information on our derivative instruments.




CRITICAL ACCOUNTING POLICIES AND ESTIMATES
 
The preparation of financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America requires us to make estimates, judgments and assumptions that affect the amounts reported in our consolidated financial statements and accompanying notes. Concurrent with our emergence from bankruptcy, we applied fresh start accounting and elected to change our accounting policies related to property and equipment as well as materials and supplies. See "Note 1 - Description of the Business and Summary of Significant Accounting Policies" and "Note 3 - Fresh Start Accounting" to our consolidated financial statements included in "Item 8. Financial Statements and Supplementary Data" for more information. Our significant accounting policies are included in "Note 1 - Description of the Business and Summary of Significant Accounting Policies" to our consolidated financial statements.statements included in "Item 8. Financial Statements and Supplementary Data". These policies, along with our underlying judgments and assumptions made in their application, have a significant impact on our consolidated financial statements.

We identify our critical accounting policies as those that are the most pervasive and important to the portrayal of our financial position and operating results and that require the most difficult, subjective and/or complex judgments regarding estimates in matters that are inherently uncertain. Our critical accounting policies are those related to property and equipment, impairment of long-lived assetsincome taxes and income taxes.pension and other post-retirement benefits.
 
Property and Equipment


Concurrent with our emergence from bankruptcy, we applied fresh start accounting and adjusted the carrying value of our drilling rigs to estimated fair value. See "Note 3 - Fresh Start Accounting" to our consolidated financial statements included in "Item 8. Financial Statements and Supplementary Data" for more information. As of December 31, 2017,2023, the carrying value of our property and equipment totaled $12.9$1.6 billion,, which represented 88%38% of total assets. This carrying value reflects the application of our property and equipment accounting policies, which incorporate our estimates, judgments and assumptions relative to the capitalized costs, useful lives and salvage values of our rigs.
 
We develop and apply property and equipment accounting policies that are designed to appropriately and consistently capitalize those costs incurred to enhance, improve and extend the useful lives of our assets and expense those costs incurred to repair or maintain the existing condition or useful lives of our assets. The development and application of such policies requires estimates, judgments and assumptions relative to the nature of, and benefits from, expenditures on our assets. We establish property and equipment accounting policies that are designed to depreciate our assets over their estimated useful lives.

Upon emergence, we elected to change our accounting policies and have identified the significant components of our drilling rigs and ascribed useful lives based on the expected time until the next required overhaul or the end of the expected economic lives of the components.

The judgments and assumptions used in determining the usefulnext overhaul or the economic lives of the components of our property and equipment reflect both historical experience and expectations regarding future operations, utilization and performance of our assets. The use of different estimates, judgments and assumptions in the establishment of our property and equipment accounting policies, especially those involving the useful lives of the significant components our rigs, would likely result in materially different asset carrying values and operating results.
 
The useful lives of our drilling rigsrig components are difficult to estimate due to a variety of factors, including technological advances that impact the methods or cost of oil and natural gas exploration and development, changes in market or economic conditions and changes in laws or regulations affecting the drilling industry. We evaluate the remaining useful lives of our rigsrig components on a periodic basis, considering operating condition, functional capability and market and economic factors.

Our fleet of 2418 floater rigs excluding two rigs under construction and one rig held-or-sale, represented 58%62% of both the gross cost and 63% of the net carrying amount of our depreciable property and equipment as of December 31, 2017.  Our floater rigs are depreciated over useful lives ranging from ten to 35 years.2023. Our fleet of 3735 jackup rigs excluding one rig under construction, represented 20%34% of the gross cost and 18%33% of the net carrying amount of our depreciable property and equipment as of December 31, 2017.  Our jackup rigs are depreciated over useful lives ranging from ten to 30 years. 2023. 



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, 2017 for various assumed changes in the useful lives of our drilling rigs effective January 1, 2017:

Impairment of Long-Lived Assets

During the years ended December 31, 2017 and 2015, we recorded pre-tax, non-cash losses on impairment of long-lived assets of $182.9 million and $2.6 billion, respectively. See Note 4 to our consolidated financial statements included in "Item 8. Financial Statements and Supplementary Data" for additional information on our property and equipment.
We evaluate the carrying value of our property and equipment, primarily our drilling rigs, when events or changes in circumstances indicate that the carrying value of such rigs may not be recoverable. Generally, extended periods of idle time and/or inability to contract rigs at economical rates are an indication that a rig may be impaired. Impairment situations may arise with respect to specific individual rigs, groups of rigs, such as a specific type of drilling rig, or rigs in a certain geographic location.

For property and equipment used in our operations, recoverability generally is determined by comparing the carrying value of an asset to the expected undiscounted future cash flows of the asset. If the carrying value of an asset is not recoverable, the amount of impairment loss is measured as the difference between the carrying value of the asset and its estimated fair value. The determination of expected undiscounted cash flow amounts requires significant estimates, judgments and assumptions, including utilization levels, day rates, expense levels and capital requirements, as well as cash flows generated upon disposition, for each of our drilling rigs. Due to the inherent uncertainties associated with these estimates, we perform sensitivity analysis on key assumptions as part of our recoverability test.

Our judgments and assumptions about future cash flows to be generated by our drilling rigs are highly subjective and based on consideration of the following:

global macroeconomic and political environment,
historical utilization, day rate and operating expense trends by asset class,
regulatory requirements such as surveys, inspections and recertification of our rigs,
remaining useful lives of our rigs,
expectations on the use and eventual disposition of our rigs,
weighted-average cost of capital,
oil price projections,
sanctioned and unsanctioned offshore project data,
offshore project break-even economic data,
global rig supply and construction orders,
global rig fleet capabilities and relative rankings, and
expectations of global rig fleet attrition.

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. 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.

The highly cyclical nature of our industry cannot be reasonably predicted with a high level of accuracy and therefore differences between our historical judgments and assumptions and actual results will occur. We reassess our judgments and assumptions in the period in which significant differences are observed and may conclude that a triggering event has occurred and perform a recoverability test. We recognized impairment charges during 2014, 2015 and 2017 upon observation of significant unexpected changes in our business climate and estimated useful lives of certain assets.

There are numerous factors underlying the highly cyclical nature of our industry that are reasonably likely to impact our judgments and assumptions including, but not limited to, the following:

changes in global economic conditions,
production levels of the Organization of Petroleum Exporting Countries (“OPEC”),
production levels of non-OPEC countries,
advances in exploration and development technology,
offshore and onshore project break-even economics,
development and exploitation of alternative fuels,
natural disasters or other operational hazards,
changes in relevant law and governmental regulations,
political instability and/or escalation of military actions in the areas we operate,
changes in the timing and rate of global newbuild rig construction, and
changes in the timing and rate of global rig fleet attrition.

There is a wide range of interrelated changes in our judgments and assumptions that could reasonably occur as a result of unexpected developments in the aforementioned factors, which could result in materially different carrying values for an individual rig, group of rigs or our entire rig fleet, materially impacting our operating results.


Income Taxes
 
We conduct operations and earn income in numerous countries and are subject to the laws of numerous tax jurisdictions. As of December 31, 2017,2023, our consolidated balance sheetConsolidated Balance Sheet included a $20.2$825.2 million net deferred income tax asset,, a $39.4$36.6 million liability for income taxes currently payable and a $178.0$224.0 million liability for unrecognized tax benefits, inclusive of interest and penalties.


The carrying values of deferred income tax assets and liabilities reflect the application of our income tax accounting policies and are based on estimates, judgments and assumptions regarding future operating results and levels of taxable income. Carryforwards and tax credits are assessed for realization as a reduction of future taxable income by using a more-likely-than-not determination. We do not offset deferred tax assets and deferred tax liabilities attributable to different tax paying jurisdictions.

We do not provide deferred taxes on the undistributed earnings of certain subsidiaries because our policy and intention is to reinvest such earnings indefinitely. Should we make a distribution from these subsidiaries in the form of dividends or otherwise, we wouldmay be subject to additional income taxes.


The carrying values of liabilities for income taxes currently payable and unrecognized tax benefits are based on our interpretation of applicable tax laws and incorporate estimates, judgments and assumptions regarding the use of tax planning strategies in various taxing jurisdictions. The use of different estimates, judgments and assumptions in connection with accounting for income taxes, especially those involving the deployment of tax planning strategies, may result in materially different carrying values of income tax assets and liabilities and operating results.




We operate in several jurisdictions where tax laws relating to the offshore drilling industry are not well developed. In jurisdictions where available statutory law and regulations are incomplete or underdeveloped, we obtain professional guidance and consider existing industry practices before utilizing tax planning strategies and meeting our tax obligations. Our tax positions are evaluated for recognition using a more-likely-than-not threshold, and those tax positions requiring recognition are measured as the largest amount of tax benefit that is greater than 50% likely of being realized upon effective settlement with a taxing authority that has full knowledge of all relevant information.

Tax returns are routinely subject to audit in most jurisdictions and tax liabilities occasionally are finalized through a negotiation process. In some jurisdictions, income tax payments may be required before a final income tax obligation is determined in order to avoid significant penalties and/or interest. While we historically have not experienced significant adjustments to previously recognized tax assets and liabilities as a result of finalizing tax returns, there can be no assurance that significant adjustments will not arise in the future. In addition, there are several factors that could cause the future level of uncertainty relating to our tax liabilities to increase, including the following:


During recent years, the number of tax jurisdictions in which we conduct operations has increased, and we currently anticipate that this trend will continue.increased.


In order to utilize tax planning strategies and conduct operations efficiently, our subsidiaries frequently enter into transactions with affiliates that are generally subject to complex tax regulations and are frequently reviewed and challenged by tax authorities.

68



We may conduct future operations in certain tax jurisdictions where tax laws are not well developed, and it may be difficult to secure adequate professional guidance.


Tax laws, regulations, agreements, treaties and the administrative practices and precedents of tax authorities change frequently, requiring us to modify existing tax strategies to conform to such changes.


We recognizedPension and Other Postretirement Benefits

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, 2023, included (1) a weighted average discount rate of 4.97% to determine pension benefit obligations, (2) a weighted average discount rate of 5.21% to determine net periodic pension cost and (3) an expected long-term rate of return on pension plan assets of 7.10% to determine net periodic pension cost. The assumed discount rate is based upon the impactaverage yield for either Moody’s or Standard & Poor'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.

Using our key assumptions at December 31, 2023, a one-percentage-point decrease in the assumed discount rate would increase our recorded pension and other postretirement benefit liabilities by approximately $60.1 million, while a one-percentage-point decrease (increase) in the expected long-term rate of return on plan assets would increase (decrease) annual net benefits cost by approximately $4.4 million. 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 enactmentrisk premium associated with the plans’ other asset classes, and the expectations for future returns of U.S. tax reform duringeach asset class. The expected return for each asset class was then weighted based upon the fourth quartercurrent asset allocation to develop the expected long-term rate of 2017return on a provisional basis. During 2018, we may make adjustmentsassets assumption for the plan, which decreased to the provisional amounts throughout the one-year measurement period as provided by Staff Accounting Bulletin No. 118, as we continue to analyze applicable information6.88% at December 31, 2023 from 7.10% at December 31, 2022.

MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING


Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) or 15d-15(f). Our internal control over financial reporting system is designed to provide reasonable assurance as to the reliability of our financial reporting and the preparation and presentation of consolidated financial statements in accordance with accounting principles generally accepted in the United States, as well as to safeguard assets from unauthorized use or disposition. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.


Under the supervision and with the participation of management, including the Chief Executive Officer and Chief Financial Officer, we have conducted an evaluation of the effectiveness of our internal control over financial reporting based on the criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on this evaluation, we have concluded that our internal control over financial reporting is effective as of December 31, 20172023 to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.

Management's assessment of the effectiveness of the Company's internal control over financial reporting as of December 31, 2017 excluded the internal control over financial reporting of Atwood Oceanics, Inc. representing total assets of $2.0 billion and total revenues of $23.3 million included in the consolidated financial statements of Ensco plc and subsidiaries as of and for the year ended December 31, 2017.


KPMG LLP, the independent registered public accounting firm who audited our consolidated financial statements, has issued an audit report on our internal control over financial reporting. KPMG LLP's audit report on our internal control over financial reporting is included herein.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
 



To the Board of Directors and Shareholders
Ensco plc:Valaris Limited:
 
Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Ensco plcValaris Limited and subsidiaries (the Company) as of December 31, 20172023 and 2016,2022, the related consolidated statements of operations, comprehensive income (loss), and cash flows for each of the years in the three‑yeartwo-year period ended December 31, 2017,2023 and for the period from May 1, 2021 to December 31, 2021 (Successor periods) and for the period from January 1, 2021 to April 30, 2021 (Predecessor period), and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 20172023 and 2016,2022, and the results of its operations and its cash flows for each of the years in the three‑year period ended December 31, 2017,Successor and Predecessor periods, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2017,2023, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated February 27, 201822, 2024 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

Basis of Presentation

As discussed in Note 1 to the consolidated financial statements, on March 3, 2021, the Bankruptcy Court for the Southern District of Texas entered an order confirming the Company’s plan for reorganization under Chapter 11, which became effective on April 30, 2021. Accordingly, the accompanying consolidated financial statements as of December 31, 2023 and 2022 and for the Successor periods have been prepared in conformity with Accounting Standards Codification 852, Reorganization, with the Company’s assets, liabilities, and capital structure having carrying amounts not comparable to prior years.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.


71


Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Income tax positions pertaining to certain tax transactions

As discussed in Notes 1 and 12 to the consolidated financial statements, the Company evaluated the income tax effect of certain transactions which often requires local country tax expertise and judgment. This requires the Company to interpret complex tax laws in multiple jurisdictions to assess whether its tax positions have a more than 50 percent likelihood of being sustained with the taxing authorities.

We identified the assessment of income tax positions pertaining to certain tax transactions as a critical audit matter. Complex auditor judgment was required to evaluate the Company’s assessment that certain tax positions have a more than 50 percent likelihood of being sustained with the taxing authorities. In addition, specialized skills and knowledge were required to evaluate the Company’s interpretation of tax laws in the applicable jurisdictions.

The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls over the Company’s income tax process. This included controls related to the interpretation of tax laws applicable to certain transactions and the assessment that tax positions pertaining to those transactions have a more than 50 percent likelihood of being sustained with taxing authorities. We involved tax professionals with specialized skills and knowledge, who assisted on evaluating the Company’s interpretation of local tax laws and assessment of whether tax positions had a greater than 50 percent likelihood of being sustained with taxing authorities.

Realizability of certain deferred tax assets

As discussed in Notes 1 and 12 to the consolidated financial statements, the Company recognizes a valuation allowance for deferred tax assets if, based on the weight of all available evidence, it is more-likely-than-not that the benefit from the deferred tax asset will not be realized. The realization of deferred tax assets is dependent upon generating sufficient taxable income during future periods in the jurisdictions it operates. As of December 31, 2023, the Company had recorded a valuation allowance of $4.2 billion on deferred tax assets. During the year ended December 31, 2023, the Company released $799.5 million of the valuation allowance recognized related to deferred tax assets.

We identified the evaluation of the realizability of certain deferred tax assets as a critical audit matter. A high degree of subjective auditor judgment was required due to (1) the significant judgment made by the Company in assessing the ability to realize the deferred tax assets and whether a valuation allowance was necessary considering the availability of forecasted income and (2) the subjective nature of the sources of possible future income used in the Company's assessment and the key assumptions used in the estimation of such future income, specifically forecasted revenue, contract drilling expenses and shore-based expenses.

72


The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls related to the Company's process to assess the realizability of certain deferred tax assets, including controls over the key assumptions used in the determination of forecasted income. We evaluated available positive and negative evidence used in the Company's assessment of whether certain deferred tax assets were more like than not to be realized in the future. We evaluated the reasonableness of the revenue, contract drilling expenses and shore-based expenses assumptions used in determining forecasted income for consistency with historical amounts, economic trends and industry data. We involved tax professionals with specialized skills and knowledge, who assisted in the application of tax laws in the performance of these procedures.

Our audit of internal control over financial reporting of the Company also excluded an evaluation of the internal control over financial reporting of Atwood Oceanics, Inc.
Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report Onon Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.



74


Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

We provide drilling services on a day rate contract basis. Under day rate contracts, we provide an integrated service that includes the provision of a drilling rig and rig crews for which we receive a daily rate that may vary between the full rate and zero rate throughout the duration of the contractual term. The day rate we earn can vary between the full day rate and zero rate,term, depending on the operations of the rig. We also may receive lump-sum fees or similar compensation for the mobilization, demobilization and capital upgrades of our rigs. 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. In addition, our customers may pay all

Chapter 11 Cases

In connection with the Chapter 11 Cases, on and personnelprior to April 30, 2021 (the "Effective Date"), Legacy Valaris effectuated certain restructuring transactions, pursuant to which the successor company, Valaris, was formed and, through a series of transactions, Legacy Valaris transferred to a subsidiary of Valaris substantially all of the subsidiaries, and other assets, of Legacy Valaris.

References to the financial position and results of operations of the "Successor" or "Successor Company" relate to the financial position and results of operations of the Company after the Effective Date. References to the financial position and results of operations of the "Predecessor" or "Predecessor Company" refer to the financial position and results of operations of Legacy Valaris on and prior to the Effective Date. References to the “Company,” “we,” “us” or “our” in this Annual Report are to Valaris Limited, together with its consolidated subsidiaries, when referring to periods following the Effective Date, and to Legacy Valaris, together with its consolidated subsidiaries, when referring to periods prior to and including Effective Date.

    AcquisitionChapter 11 Cases. Upon emergence from the Chapter 11 Cases, we qualified for and adopted fresh start accounting. The application of Atwood Oceanics, Inc.

On October 6, 2017 (the "Merger Date"), we completed a merger transaction (the "Merger") with Atwood Oceanics, Inc. ("Atwood") and Echo Merger Sub, LLC, a wholly-owned subsidiary of Ensco plc. Pursuant to the merger agreement, Echo Merger Sub, LLC merged with and into Atwood, with Atwood as the surviving entity and an indirect, wholly-owned subsidiary of Ensco plc. Total consideration delivered in the Merger consisted of 132.2 million of our Class A ordinary shares and $11.1 million of cash in settlement of certain share-based payment awards. The total aggregate value of consideration transferred was $781.8 million. Additionally, upon closing of the Merger, we utilized cash acquired of $445.4 million and cash on hand to extinguish Atwood's revolving credit facility, outstanding senior notes and accrued interest totaling $1.3 billion. The estimated fair values assigned to assets acquired net of liabilities assumed exceeded the consideration transferred, resultingfresh start accounting resulted in a bargain purchase gainnew basis of $140.2 millionaccounting, and the Company became a new entity for financial reporting purposes. Accordingly, our financial statements and notes after the Effective Date are not comparable to our financial statements and notes on and prior to that was recognized duringdate.

Accounting Policies


Principles of Consolidation


The accompanying consolidated financial statements include the accounts of Ensco plc,Valaris Limited, those of our wholly-owned subsidiaries and entities in which we hold a controlling financial interest. All intercompany accounts and transactions have been eliminated. Investments in operating entities in which we have the ability to exercise significant influence, but where we do not control operating and financial policies are accounted for using the equity method. Significant influence generally exists if we have an ownership interest representing between 20% and 50% of the voting stock of the investee. We account for our interest in ARO using the equity method of accounting and only recognize our portion of equity in earnings in our consolidated financial statements. ARO is a variable interest entity; however, we are not the primary beneficiary and therefore do not consolidate ARO.

Reclassification

Certain previously reported amounts have been reclassified to conform to the current year presentation.


Pervasiveness of Estimates


The preparation of financial statements in conformity with U.S. GAAP requires us to make certain estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, the related revenues and expenses and disclosures of gain and loss contingencies as of the date of the financial statements. Actual results could differ from those estimates.


Foreign Currency Remeasurement and Translation


Our functional currency is the U.S. dollar. As is customary in the oil and gas industry, a majority of our revenues and expenses are denominated in U.S. dollars; however, a portion of the revenues earned and expenses incurred by certain of our subsidiaries are denominated in currencies other than the U.S. dollar. These transactions are remeasured in U.S. dollars based on a combination of both current and historical exchange rates. Most transaction gains and losses including certain gains and losses on our derivative instruments, are included in other,Other, net, in our consolidated statementConsolidated Statements of operations.Operations.  Certain gains and losses from the translation of foreign currency balances of our non-U.S. dollar functional currency subsidiaries are included in accumulatedAccumulated other comprehensive income on our consolidated balance sheet.Consolidated Balance Sheet. Net foreign currency exchange loss was $3.5 million, and gains were $12.2 million, $8.1 million and losses, inclusive of offsetting fair value derivatives, were $5.1$13.4 million, of losses, $6.0 million of losses and $5.4 million of gains, and were included in other,Other, net, in our consolidated statementsConsolidated Statements of operationsOperations for the years ended December 31, 2017, 20162023 and 20152022, eight months ended December 31, 2021 (Successor), and four months ended April 30, 2021 (Predecessor), respectively.

Cash Equivalents and Short-Term Investments


Highly liquid investments with maturities of three months or less at the date of purchase are considered cash equivalents. Highly liquid investments with maturities of greater than three months but less than one year at the date of purchase are classified as short-term investments.


Short-termThere were no short-term investments consisted of time deposits with initial maturities in excess of three months but less than one year and totaled $440.0 million and $1.4 billion as of December 31, 20172023 and 2016, respectively.2022. Cash flows from purchases and maturities of short-term investments were classified as investing activities in our consolidated statementsConsolidated Statements of cash flowsCash Flows for the yearsyear ended December 31, 2017, 2016 and 2015.2022. To mitigate our credit risk, our investments in time deposits arehave historically been diversified across multiple, high-quality financial institutions.
    
Property and Equipment


All costs incurred in connection with the acquisition, construction, major enhancement and improvement of assets are capitalized, including allocations of interest incurred during periods that our drilling rigs are under construction or undergoing major enhancements and improvements. Costs incurred to place an asset into service are capitalized, including costs related to the initial mobilization of a newbuild drilling rig that are not reimbursed by the customer.rig. Repair and maintenance costs are charged to contract drilling expense in the period in which they are incurred. Upon the sale or retirement of assets, the related cost and accumulated depreciation are removed from the balance sheet, and the resulting gain or loss is included in contractOther, net in our Consolidated Statements of Operations.

Upon emergence, we elected to change our accounting policies and have identified the significant components of our drilling expense, unless reclassified to discontinued operations.rigs and ascribed useful lives based on the expected time until the next required overhaul or the end of the expected economic lives of the components.


Our property and equipment is depreciated on a straight-line basis, after allowing for salvage values, over the estimated useful lives of our assets. Drilling rigs and related equipment are depreciated over estimated useful lives ranging from fourfive to 35 years. Buildings and improvements are depreciated over estimated useful lives ranging from


seven 10 to 30 years. Other equipment, including computer and communications hardware and software, costs, is depreciated over estimated useful lives ranging from threetwo to six years.


We evaluate the carrying value of our property and equipment, for impairment whenprimarily our drilling rigs, on a quarterly basis to identify events or changes in circumstances ("triggering events") that indicate that the carrying value of such assetsrigs may not be recoverable. For property and equipment used in our operations, recoverability generally is determined by comparing the carrying value of an asset to the expected undiscounted future cash flows of the asset. If the carrying value of an asset is not recoverable, the amount of impairment loss is measured as the difference between the carrying value of the asset and its estimated fair value. Property and equipment held-for-sale is recorded at the lower of net book value or fair value less cost to sell.


During 2017 and 2015, weWe recorded pre-tax, non-cash impairment losses on impairment ofrelated to long-lived assets of $182.9$34.5 million and $2.6 billion.$756.5 million, in the year ended December 31, 2022 (Successor) and the four months ended April 30, 2021 (Predecessor), respectively. See "Note 4"Note 7 - Property and Equipment" for additional information on these impairments.

If the global economy deteriorates and/or our expectations relative to future offshore drilling industry conditions decline, it is reasonably possible that additional impairment charges may occur with respect to specific individual rigs, groups of rigs, such as a specific type of drilling rig, or rigs in a certain geographic location.charges.
    
Operating Revenues and Expenses

Our drilling contracts are performed on a day rate basis, and the terms of such contracts are typicallySee "Note 4 - Revenue from Contracts with Customers" for a specific period of time or the period of time required to complete a specific task, such as drill a well. Contract revenues and expenses are recognized on a per day basis, as the work is performed.

In connection with some contracts, we receive lump-sum fees or similar compensation for the mobilization of equipment and personnel prior to the commencement of drilling services or the demobilization of equipment and personnel upon contract completion. Fees received for the mobilization or demobilization of equipment and personnel are included in operating revenues. The costs incurred in connection with the mobilization and demobilization of equipment and personnel are included in contract drilling expense.

Mobilization fees received and costs incurred prior to commencement of drilling operations are deferred and amortized on a straight-line basis over the period that the related drilling services are performed. Demobilization fees and related costs are recognized as incurred upon contract completion. Costs associated with the mobilization of equipment and personnel to more promising market areas without contracts are expensed as incurred.

Deferred mobilization costs were included in other current assets and other assets, net,information on our consolidated balance sheetsaccounting policies for revenue recognition and totaled $39.9 million and $43.9 million as of December 31, 2017 and 2016, respectively. Deferred mobilization revenue was included in accrued liabilities and other, and other liabilities on our consolidated balance sheets and totaled $35.7 million and $62.1 million as of December 31, 2017 and 2016, respectively.

In connection with some contracts, we receive up-front lump-sum fees or similar compensation for capital improvements to our drilling rigs. Such compensation is deferred and amortized to revenue over the periodcertain operating costs that the related drilling services are performed, and the cost is capitalized and depreciated over the useful life of the asset. Deferred revenue associated with capital improvements was included in accrued liabilities and other, and other liabilities on our consolidated balance sheets and totaled $87.4 million and $165.2 million as of December 31, 2017 and 2016, respectively.

We may receive termination fees if certain drilling contracts are terminated by the customer prior to the end of the contractual term. Such compensation is recognized as revenues when services have been completed under the terms of the contract, the termination fee can be reasonably measured and collectability is reasonably assured.

For the year ended December 31, 2016, operating revenues included $185.0 million for the lump-sum consideration received in settlement and release of the ENSCO DS-9 customer's ongoing early termination obligations. The ENSCO DS-9 contract was terminated for convenience by the customer in July 2015, whereby the customer was


obligated to pay us monthly termination fees for two years under the termination provisions of the contract. Operating revenues in 2016 also included $20.0 million for the lump-sum consideration received in settlement of the ENSCO 8503 customer's remaining obligations under the contract.
For the year ended December 31, 2015, operating revenues included $129.0 million related to the lump-sum payments associated with the ENSCO DS-4 and ENSCO DS-9 contract terminations.

We must obtain certifications from various regulatory bodies in order to operate our drilling rigs and must maintain such certifications through periodic inspections and surveys. The costs incurred in connection with maintaining such certifications, including inspections, tests, surveys and drydock, as well as remedial structural work and other compliance costs, are deferred and amortized over the corresponding certificationfuture periods. Deferred regulatory certification and compliance costs were included in other current assets and other assets, net, on our consolidated balance sheets and totaled $15.3 million and $14.9 million as of December 31, 2017 and 2016, respectively.
    
Derivative Instruments
82



We use derivatives to reduce our exposure to various market risks, primarily foreign currency exchange rate risk. See "Note 6 - Derivative Instruments" for additional information on how and why we use derivatives.

All derivatives are recorded on our consolidated balance sheet at fair value. Derivatives subject to legally enforceable master netting agreements are not offset on our consolidated balance sheet. Accounting for the gains and losses resulting from changes in the fair value of derivatives depends on the use of the derivative and whether it qualifies for hedge accounting. Derivatives qualify for hedge accounting when they are formally designated as hedges and are effective in reducing the risk exposure that they are designated to hedge. Our assessment of hedge effectiveness is formally documented at hedge inception, and we review hedge effectiveness and measure any ineffectiveness throughout the designated hedge period on at least a quarterly basis.

Changes in the fair value of derivatives that are designated as hedges of the variability in expected future cash flows associated with existing recognized assets or liabilities or forecasted transactions ("cash flow hedges") are recorded in accumulated other comprehensive income ("AOCI").  Amounts recorded in AOCI associated with cash flow hedges are subsequently reclassified into contract drilling, depreciation or interest expense as earnings are affected by the underlying hedged forecasted transactions.

Gains and losses on a cash flow hedge, or a portion of a cash flow hedge, that no longer qualifies as effective due to an unanticipated change in the forecasted transaction are recognized currently in earnings and included in other, net, in our consolidated statement of operations based on the change in the fair value of the derivative. When a forecasted transaction becomes probable of not occurring, gains and losses on the derivative previously recorded in AOCI are reclassified currently into earnings and included in other, net, in our consolidated statement of operations.

We occasionally enter into derivatives that hedge the fair value of recognized assets or liabilities, but do not designate such derivatives as hedges or the derivatives otherwise do not qualify for hedge accounting. In these situations, a natural hedging relationship generally exists where changes in the fair value of the derivatives offset changes in the fair value of the underlying hedged items. Changes in the fair value of these derivatives are recognized currently in earnings in other, net, in our consolidated statement of operations.

Derivatives with asset fair values are reported in other current assets or other assets, net, on our consolidated balance sheet depending on maturity date. Derivatives with liability fair values are reported in accrued liabilities and other, or other liabilities on our consolidated balance sheet depending on maturity date.



Income Taxes


We conduct operations and earn income in numerous countries. Current income taxes are recognized for the amount of taxes payable or refundable based on the laws and income tax rates in the taxing jurisdictions in which operations are conducted and income is earned.

Deferred tax assets and liabilities are recognized for the anticipated future tax effects of temporary differences between the financial statement basis and the tax basis of our assets and liabilities using the enacted tax rates in effect at year-end. A valuation allowance for deferred tax assets is recorded when it is more-likely-than-not that the benefit from the deferred tax asset will not be realized. We do not offset deferred tax assets and deferred tax liabilities attributable to different tax paying jurisdictions.

We operate in certain jurisdictions where tax laws relating to the offshore drilling industry are not well developed and change frequently. Furthermore, we may enter into transactions with affiliates or employ other tax planning strategies that generally are subject to complex tax regulations. As a result of the foregoing, the tax liabilities and assets we recognize in our financial statements may differ from the tax positions taken, or expected to be taken, in our tax returns. Our tax positions are evaluated for recognition as unrecognized tax benefits using a more-likely-than-not threshold, and those tax positions requiring recognition are measured as the largest amount of tax benefit that is greater than 50% likely of being realized upon effective settlement with a taxing authority that has full knowledge of all relevant information. Interest and penalties relating to income taxes are included in currentCurrent income tax expense in our consolidated statementConsolidated Statements of operations.Operations.


Our drilling rigs frequently move from one taxing jurisdiction to another based on where they are contracted to perform drilling services. The movement of drilling rigs among taxing jurisdictions may involve a transfer of drilling rig ownership among our subsidiaries (“through an intercompany rig sale”).sale. The pre-tax profit resulting from an intercompany rig sale is eliminated from our consolidated financial statements, and the carrying value of a rig sold in an intercompany transaction remains at historical net depreciated cost prior to the transaction. Our consolidated financial statements do not reflect the asset disposition transaction of the selling subsidiary or the asset acquisition transaction of the acquiring subsidiary. Prior to our adoption of Accounting Standards Update 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory (“Update 2016-16”) on January 1, 2017, income taxes resulting from an intercompany rig sale, as well as the tax effect of any reversing temporary differences resulting from the sale, were deferred and amortized on a straight-line basis over the remaining useful life of the rig. Subsequent to our adoption of Update 2016-16, theThe income tax effects resulting from intercompany rig sales are recognized in earnings in the period in which the sale occurs.


In some instances, we may determine that certain temporary differences will not result in a taxable or deductible amount in future years, as it is more-likely-than-not we will commence operations and depart from a given taxing jurisdiction without such temporary differences being recovered or settled. Under these circumstances, no future tax consequences are expected and no deferred taxes are recognized in connection with such operations. We evaluate these determinations on a periodic basis and, in the event our expectations relative to future tax consequences change, the applicable deferred taxes are recognized or derecognized.

We do not provide deferred taxes on the undistributed earnings of certain subsidiaries because our policy and intention is to reinvest such earnings indefinitely. The U.S. Tax Cuts and Jobs Act (“U.S. tax reform”) was enacted on December 22, 2017 and introduced significant changes to U.S. income tax law, includingShould we make a reductiondistribution from these subsidiaries in the statutoryform of dividends or otherwise, we may be subject to additional income tax rate from 35% to 21% effective January 1, 2018, a base erosion anti-abuse tax that effectively imposes a minimum tax on certain payments to non-U.S. affiliates and new and revised rules relating to the current taxation of certain income of foreign subsidiaries. See "Note 10 - Income Taxes" for additional information.taxes.




Share-Based Compensation


We sponsor share-based compensation plans that provide equity compensation to our key employees, officers and non-employee directors. Our Long-Term2021 Management Incentive Plan (the “2012 LTIP”“MIP”) allows our Boardboard of Directorsdirectors to authorize shareequity-based grants to be settled in cash, shares or shares.a combination of shares and cash. Compensation expense for sharetime-based equity awards to be settled in shares is measured at fair value on the date of grant and recognized on a straight-line basis over the requisite service period (usually the vesting period). Compensation expense for shareperformance awards is recognized over the requisite service period using the accelerated method and is reduced for forfeited awards in the period in which the forfeitures occur. For our performance awards that cliff vest and require the employee to render service through the vesting date, even though attainment of performance objectives might be earlier, our expense under the accelerated method would be a ratable expense over
83


the vesting period. Equity settled performance awards generally vest at the end of a three-year measurement period based on attainment of performance goals. The estimated probable outcome of attainment of the specified performance goals is based primarily on relative performance over the requisite performance period. Any subsequent changes in cash is remeasured each quarter withthis estimate as it relates to performance objectives are recognized as a cumulative adjustment to compensation cost duringin the period in which the change in estimate occurs, except in the case of objectives based on changes ina market condition, such as our sharestock price. Compensation cost for awards based on a market performance objective is recognized as long as the requisite service period is completed and will not be reversed even if the market-based objective is never satisfied. Any adjustments to the compensation cost recognized in our consolidated statementConsolidated Statements of operationsOperations for awards that are forfeited are recognized in the period in which the forfeitures occur. See "Note 8"Note 10 - Benefit Plans"Share Based Compensation" for additional information on our share-based compensation.


Pension and Other Post-retirement Benefit Plans

We measure our actuarially determined obligations and related costs for our defined benefit pension and other post-retirement plans, retiree life and medical supplemental plan benefits by applying assumptions, the most significant of which include long-term rate of return on plan assets, discount rates and mortality rates. For the long-term rate of return, we develop our assumptions regarding the expected rate of return on plan assets based on historical experience and projected long-term investment returns, and we weight the assumptions based on each plan's asset allocation. For the discount rate, we base our assumptions on a yield curve approach. Actual results may differ from the assumptions included in these calculations. If gains or losses exceed 10% of the greater of the plan assets or plan liabilities, we amortize such gains or losses into income over either the period of expected future service of active participants, or over the expected average remaining lifetime of all participants. We recognize gains or losses related to plan curtailments at the date the plan amendment or termination is adopted which may precede the effective date.
Fair Value Measurements


We measure certain of our assets and liabilities based on a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy assigns the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities ("Level 1") and the lowest priority to unobservable inputs ("Level 3"). Level 2 measurements represent inputs that are observable for similar assets or liabilities, either directly or indirectly, other than quoted prices included within Level 1.  See "Note 3"Note 6 - Fair Value Measurements" for additional information on the fair value measurement of certain of our assets and liabilities.


Noncontrolling Interests


Third parties hold a noncontrolling ownership interest in certain of our non-U.S. subsidiaries. Noncontrolling interests are classified as equity on our consolidated balance sheetConsolidated Balance Sheet, and net income attributable to noncontrolling interests is presented separately in our consolidated statementConsolidated Statements of operations.

New Accounting PronouncementsProperty and Equipment

In August 2017,Concurrent with our emergence from bankruptcy, we applied fresh start accounting and adjusted the Financial Accounting Standards Board (the "FASB")issued Update 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvementscarrying value of our drilling rigs to Accounting for Hedging Activities (estimated fair value. See "Update 2017-12"), which will make more hedging strategies eligible for hedge accounting. It also amends presentation and disclosure requirements and changes how companies assess effectiveness. This update is effective for annual and interim periods beginning after December 15, 2018, with early adoption permitted. We are currently evaluating the effect that Update 2017-12 will have onNote 3 - Fresh Start Accounting" to our consolidated financial statements included in "Item 8. Financial Statements and related disclosures.Supplementary Data" for more information. As of December 31, 2023, the carrying value of our property and equipment totaled $1.6 billion, which represented 38% of total assets. This carrying value reflects the application of our property and equipment accounting policies, which incorporate our estimates, judgments and assumptions relative to the capitalized costs, useful lives and salvage values of our rigs.

In October 2016,We develop and apply property and equipment accounting policies that are designed to appropriately and consistently capitalize those costs incurred to enhance, improve and extend the FASB issued Accounting Standards Update 2016-16, useful lives of our assets and expense those costs incurred to repair or maintain the existing condition or useful lives of our assets. The development and application of such policies requires estimates, judgments and assumptions relative to the nature of, and benefits from, expenditures on our assets. We establish property and equipment accounting policies that are designed to depreciate our assets over their estimated useful lives.

Upon emergence, we elected to change our accounting policies and have identified the significant components of our drilling rigs and ascribed useful lives based on the expected time until the next required overhaul or the end of the expected economic lives of the components.

The judgments and assumptions used in determining the next overhaul or the economic lives of the components of our property and equipment reflect both historical experience and expectations regarding future operations, utilization and performance of our assets. The use of different estimates, judgments and assumptions in the establishment of our property and equipment accounting policies, especially those involving the useful lives of the significant components our rigs, would likely result in materially different asset carrying values and operating results.
The useful lives of our drilling rig components are difficult to estimate due to a variety of factors, including technological advances that impact the methods or cost of oil and natural gas exploration and development, changes in market or economic conditions and changes in laws or regulations affecting the drilling industry. We evaluate the remaining useful lives of our rig components on a periodic basis, considering operating condition, functional capability and market and economic factors.

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

Our fleet of 18 floater rigs represented 62% of the gross cost and 63% of the net carrying amount of our depreciable property and equipment as of December 31, 2023. Our fleet of 35 jackup rigs represented 34% of the gross cost and 33% of the net carrying amount of our depreciable property and equipment as of December 31, 2023. 

Income Taxes (Topic 740): Intra-Entity Transfers
We conduct operations and earn income in numerous countries and are subject to the laws of Assets Other Than Inventory (“Update 2016-16”), which requires entities to recognize thenumerous tax jurisdictions. As of December 31, 2023, our Consolidated Balance Sheet included a $825.2 million net deferred income tax consequencesasset, a $36.6 million liability for income taxes currently payable and a $224.0 million liability for unrecognized tax benefits, inclusive of an intra-entity transferinterest and penalties.

The carrying values of an asset other than inventory whendeferred income tax assets and liabilities reflect the transaction occursapplication of our income tax accounting policies and are based on estimates, judgments and assumptions regarding future operating results and levels of taxable income. Carryforwards and tax credits are assessed for realization as opposed to deferringa reduction of future taxable income by using a more-likely-than-not determination. We do not offset deferred tax consequencesassets and amortizing them into future periods. We adopted Update 2016-16 on a modified retrospective basis effective January 1, 2017. As a result of modified retrospective application, we reduced prepaid taxes on intercompany transfers of property and related deferred tax liabilities resulting in the recognition of a cumulative-effect reduction in retained earnings of $14.1 million on our consolidated balance sheet as of January 1, 2017.attributable to different tax paying jurisdictions.

In March 2016, the FASB issued Accounting Standards Update 2016-09, Compensation — Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting ("Update 2016-09"), which simplifies several aspects of accounting for share-based payment transactions including the income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. We adopted Update 2016-09 effective January 1, 2017. Our adoption of Update 2016-09 did not result in any cumulative effect


on retained earnings and no adjustments have been made to prior periods. The new standard will cause volatility in our effective tax rates primarily due to the new requirement to recognize additional tax benefits or expenses in earnings related to the vesting or settlement of employee share-based awards, rather than in additional paid-in capital, during the period in which they occur. Furthermore, forfeitures are now recorded as they occur as opposed to estimating an allowance for future forfeitures.

During 2014, the FASB issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers (Topic 606) ("Update 2014-09"), which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. Update 2014-09 is effective for annual and interim periods for fiscal years beginning after December 15, 2017. Subsequent to the issuance of Update 2014-09, the FASB issued several additional Accounting Standards Updates to clarify implementation guidance, provide narrow-scope improvements and provide additional disclosure guidance. Update 2014-09 will replace most existing revenue recognition guidance in U.S. GAAP and may be adopted using a retrospective, modified retrospective or prospective with a cumulative catch-up approach. Due to the significant interaction between Update 2014-09 and Accounting Standards Update 2016-02, Leases (Topic 842): Amendments to the FASB Accounting Standards Codification ("Update 2016-02"), we will adopt Update 2014-09 and Update 2016-02 concurrently with an effective date of January 1, 2018. A substantial portion of our revenues will be recognized under Update 2016-02; therefore, Update 2014-09 will not have a significant impact on our revenue recognition patterns. However, certain additional disclosures will be required upon adoption.

During 2016, the FASB issued Update 2016-02, which requires an entity to recognize lease assets and lease liabilities on the balance sheet and to disclose key qualitative and quantitative information about the entity's leasing arrangements. This update is effective for annual and interim periods beginning after December 15, 2018, with early adoption permitted. During our evaluation of Update 2016-02, we concluded that our drilling contracts contain a lease component. In January 2018, the FASB issued a Proposed Accounting Standard Update to provide targeted improvements to Update 2016-02 which (1) provides for a new transition method whereby entities may elect to adopt the Update using a prospective with cumulative catch-up approach and, (2) provides lessors with a practical expedient to not separate non-lease components from the related lease components, by class of underlying asset. Application of the practical expedient would result in a combined single lease component that, provided specified conditions are met, would be classified as an operating lease for lessors. We expect to elect both provisions afforded under the Proposed Accounting Standard Update. We do not expectprovide deferred taxes on the undistributed earnings of certain subsidiaries because our policy and intention is to reinvest such earnings indefinitely. Should we make a significant cumulative-effect adjustmentdistribution from these subsidiaries in the periodform of adoption,dividends or otherwise, we may be subject to additional income taxes.

The carrying values of liabilities for income taxes currently payable and unrecognized tax benefits are based on our interpretation of applicable tax laws and incorporate estimates, judgments and assumptions regarding the use of tax planning strategies in various taxing jurisdictions. The use of different estimates, judgments and assumptions in connection with accounting for income taxes, especially those involving the deployment of tax planning strategies, may result in materially different carrying values of income tax assets and liabilities and operating results.

We operate in several jurisdictions where tax laws relating to the offshore drilling industry are not well developed. In jurisdictions where available statutory law and regulations are incomplete or underdeveloped, we doobtain professional guidance and consider existing industry practices before utilizing tax planning strategies and meeting our tax obligations. Our tax positions are evaluated for recognition using a more-likely-than-not threshold, and those tax positions requiring recognition are measured as the largest amount of tax benefit that is greater than 50% likely of being realized upon effective settlement with a taxing authority that has full knowledge of all relevant information.

Tax returns are routinely subject to audit in most jurisdictions and tax liabilities occasionally are finalized through a negotiation process. In some jurisdictions, income tax payments may be required before a final income tax obligation is determined in order to avoid significant penalties and/or interest. While we historically have not expect aexperienced significant changeadjustments to our pattern of revenue recognition as compared to current GAAP. However,previously recognized tax assets and liabilities as a result of finalizing tax returns, there can be no assurance that significant adjustments will not arise in the adoptionfuture. In addition, there are several factors that could cause the future level of Update 2016-12,uncertainty relating to our tax liabilities to increase, including the following:

During recent years, the number of tax jurisdictions in which we willconduct operations has increased.

In order to utilize tax planning strategies and conduct operations efficiently, our subsidiaries frequently enter into transactions with affiliates that are generally subject to complex tax regulations and are frequently reviewed and challenged by tax authorities.
68



We may conduct future operations in certain tax jurisdictions where tax laws are not well developed, and it may be requireddifficult to present increased disclosuressecure adequate professional guidance.

Tax laws, regulations, agreements, treaties and the administrative practices and precedents of tax authorities change frequently, requiring us to modify existing tax strategies to conform to such changes.

Pension and Other Postretirement Benefits

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, 2023, included (1) a weighted average discount rate of 4.97% to determine pension benefit obligations, (2) a weighted average discount rate of 5.21% to determine net periodic pension cost and (3) an expected long-term rate of return on pension plan assets of 7.10% to determine net periodic pension cost. The assumed discount rate is based upon the average yield for either Moody’s or Standard & Poor'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.

Using our key assumptions at December 31, 2023, a one-percentage-point decrease in the assumed discount rate would increase our recorded pension and other postretirement benefit liabilities by approximately $60.1 million, while a one-percentage-point decrease (increase) in the expected long-term rate of return on plan assets would increase (decrease) annual net benefits cost by approximately $4.4 million. 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 naturerisk premium associated with the plans’ other asset classes, and the expectations for future returns of our leasing arrangements as well as certain other qualitativeeach 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 decreased to 6.88% at December 31, 2023 from 7.10% at December 31, 2022. See "Note 11 - Pension and quantitative disclosures. With respect to leases whereby we are the lessee, we expect to recognize lease liabilities and offsetting "right of use" assets ranging from approximately $70 million to $90 million.

MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) or 15d-15(f). Our internal control over financial reporting system is designed to provide reasonable assurance as to the reliability of our financial reporting and the preparation and presentation of consolidated financial statements in accordance with accounting principles generally accepted in the United States, as well as to safeguard assets from unauthorized use or disposition. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Under the supervision and with the participation of management, including the Chief Executive Officer and Chief Financial Officer, we have conducted an evaluation of the effectiveness of our internal control over financial reporting based on the criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on this evaluation, we have concluded that our internal control over financial reporting is effective as of December 31, 2023 to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.

KPMG LLP, the independent registered public accounting firm who audited our consolidated financial statements, has issued an audit report on our internal control over financial reporting. KPMG LLP's audit report on our internal control over financial reporting is included herein.

Atwood’s financial results are included in our consolidated results beginningShareholders
Valaris Limited:
Opinion on the Merger Date.Consolidated Financial Statements


The Merger is expected to strengthen our positionWe have audited the accompanying consolidated balance sheets of Valaris Limited and subsidiaries (the Company) as of December 31, 2023 and 2022, the leader in offshore drilling across a wide range of water depths around the world. The Merger significantly enhances the capabilities of our rig fleet and improves our ability to meet future customer demand with the highest-specification assets. Revenues of Atwood from the Merger Date included in ourrelated consolidated statements of operations, comprehensive income (loss), and cash flows for each of the years in the two-year period ended December 31, 2023 and for the period from May 1, 2021 to December 31, 2021 (Successor periods) and for the period from January 1, 2021 to April 30, 2021 (Predecessor period), and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for Successor and Predecessor periods, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated February 22, 2024 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

Basis of Presentation

As discussed in Note 1 to the consolidated financial statements, on March 3, 2021, the Bankruptcy Court for the Southern District of Texas entered an order confirming the Company’s plan for reorganization under Chapter 11, which became effective on April 30, 2021. Accordingly, the accompanying consolidated financial statements as of December 31, 2023 and 2022 and for the Successor periods have been prepared in conformity with Accounting Standards Codification 852, Reorganization, with the Company’s assets, liabilities, and capital structure having carrying amounts not comparable to prior years.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were $23.3communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Income tax positions pertaining to certain tax transactions

As discussed in Notes 1 and 12 to the consolidated financial statements, the Company evaluated the income tax effect of certain transactions which often requires local country tax expertise and judgment. This requires the Company to interpret complex tax laws in multiple jurisdictions to assess whether its tax positions have a more than 50 percent likelihood of being sustained with the taxing authorities.

We identified the assessment of income tax positions pertaining to certain tax transactions as a critical audit matter. Complex auditor judgment was required to evaluate the Company’s assessment that certain tax positions have a more than 50 percent likelihood of being sustained with the taxing authorities. In addition, specialized skills and knowledge were required to evaluate the Company’s interpretation of tax laws in the applicable jurisdictions.

The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls over the Company’s income tax process. This included controls related to the interpretation of tax laws applicable to certain transactions and the assessment that tax positions pertaining to those transactions have a more than 50 percent likelihood of being sustained with taxing authorities. We involved tax professionals with specialized skills and knowledge, who assisted on evaluating the Company’s interpretation of local tax laws and assessment of whether tax positions had a greater than 50 percent likelihood of being sustained with taxing authorities.

Realizability of certain deferred tax assets

As discussed in Notes 1 and 12 to the consolidated financial statements, the Company recognizes a valuation allowance for deferred tax assets if, based on the weight of all available evidence, it is more-likely-than-not that the benefit from the deferred tax asset will not be realized. The realization of deferred tax assets is dependent upon generating sufficient taxable income during future periods in the jurisdictions it operates. As of December 31, 2023, the Company had recorded a valuation allowance of $4.2 billion on deferred tax assets. During the year ended December 31, 2023, the Company released $799.5 million of the valuation allowance recognized related to deferred tax assets.

We identified the evaluation of the realizability of certain deferred tax assets as a critical audit matter. A high degree of subjective auditor judgment was required due to (1) the significant judgment made by the Company in assessing the ability to realize the deferred tax assets and whether a valuation allowance was necessary considering the availability of forecasted income and (2) the subjective nature of the sources of possible future income used in the Company's assessment and the key assumptions used in the estimation of such future income, specifically forecasted revenue, contract drilling expenses and shore-based expenses.

72


The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls related to the Company's process to assess the realizability of certain deferred tax assets, including controls over the key assumptions used in the determination of forecasted income. We evaluated available positive and negative evidence used in the Company's assessment of whether certain deferred tax assets were more like than not to be realized in the future. We evaluated the reasonableness of the revenue, contract drilling expenses and shore-based expenses assumptions used in determining forecasted income for consistency with historical amounts, economic trends and industry data. We involved tax professionals with specialized skills and knowledge, who assisted in the application of tax laws in the performance of these procedures.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


To the Board of Directors and Shareholders
Valaris Limited:

Opinion on Internal Control Over Financial Reporting
We have audited Valaris Limited and subsidiaries’ (the Company) internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2023 and 2022, the related consolidated statements of operations, comprehensive income (loss), and cash flows for each of the years in the two-year period ended December 31, 2023 and for the period from May 1, 2021 to December 31, 2021 (Successor periods) and for the period from January 1, 2021 to April 30, 2021 (Predecessor period), and the related notes (collectively, the consolidated financial statements), and our report dated February 22, 2024 expressed an unqualified opinion on those consolidated financial statements.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

74


Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

VALARIS LIMITED AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
1.  DESCRIPTION OF THE BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Business
We are a leading provider of offshore contract drilling services to the international oil and gas industry with operations in almost every major offshore market across six continents. We own the world's largest offshore drilling rig fleet, including one of the newest ultra-deepwater fleets in the industry and a leading premium jackup fleet. We currently own 53 rigs, including 13 drillships, four dynamically positioned semisubmersible rigs, one moored semisubmersible rig, 35 jackup rigs and a 50% equity interest in Saudi Aramco Rowan Offshore Drilling Company ("ARO"), our 50/50 unconsolidated joint venture with Saudi Aramco, which owns an additional eight rigs.

Our customers include many of the leading international and government-owned oil and gas companies, in addition to many independent operators. We are among the most geographically diverse offshore drilling companies with global operations. The markets in which we operate include the Gulf of Mexico, South America, the North Sea, the Middle East, Africa and Asia Pacific.

We provide drilling services on a day rate contract basis. Under day rate contracts, we provide an integrated service that includes the provision of a drilling rig and rig crews for which we receive a daily rate that may vary between the full rate and zero rate throughout the duration of the contractual term, depending on the operations of the rig. We also may receive lump-sum fees or similar compensation for the mobilization, demobilization and capital upgrades of our rigs. 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.

Chapter 11 Cases

On August 19, 2020 (the “Petition Date”), Valaris plc (“Legacy Valaris” or “Predecessor”) and certain of its direct and indirect subsidiaries (collectively, the “Debtors”) filed voluntary petitions for reorganization under chapter 11 of the United States Bankruptcy Code ("Bankruptcy Code") in the Bankruptcy Court for the Southern District of Texas (the "Bankruptcy Court") The Debtors obtained joint administration of their chapter 11 cases under the caption In re Valaris plc, et al., Case No. 20-34114 (MI) (the “Chapter 11 Cases”).

In connection with the Chapter 11 Cases, on and prior to April 30, 2021 (the "Effective Date"), Legacy Valaris effectuated certain restructuring transactions, pursuant to which the successor company, Valaris, was formed and, through a series of transactions, Legacy Valaris transferred to a subsidiary of Valaris substantially all of the subsidiaries, and other assets, of Legacy Valaris.

References to the financial position and results of operations of the "Successor" or "Successor Company" relate to the financial position and results of operations of the Company after the Effective Date. References to the financial position and results of operations of the "Predecessor" or "Predecessor Company" refer to the financial position and results of operations of Legacy Valaris on and prior to the Effective Date. References to the “Company,” “we,” “us” or “our” in this Annual Report are to Valaris Limited, together with its consolidated subsidiaries, when referring to periods following the Effective Date, and to Legacy Valaris, together with its consolidated subsidiaries, when referring to periods prior to and including Effective Date.

SeeNote 2 – Chapter 11 Proceedings” for additional details regarding the Chapter 11 Cases.

80


Fresh Start Accounting

On the Effective Date, the Debtors emerged from the Chapter 11 Cases. Upon emergence from the Chapter 11 Cases, we qualified for and adopted fresh start accounting. The application of fresh start accounting resulted in a new basis of accounting, and the Company became a new entity for financial reporting purposes. Accordingly, our financial statements and notes after the Effective Date are not comparable to our financial statements and notes on and prior to that date. Furthermore, the consolidated financial statements and notes have been presented with a black line division to delineate the lack of comparability between the Predecessor and Successor.

See “Note 2 – Chapter 11 Proceedings” and “Note 3 - Fresh Start Accounting” for additional details regarding the Chapter 11 Cases and fresh start accounting.

Accounting Policies

Principles of Consolidation

The accompanying consolidated financial statements include the accounts of Valaris Limited, those of our wholly-owned subsidiaries and entities in which we hold a controlling financial interest. All intercompany accounts and transactions have been eliminated. Investments in operating entities in which we have the ability to exercise significant influence, but where we do not control operating and financial policies are accounted for using the equity method. Significant influence generally exists if we have an ownership interest representing between 20% and 50% of the voting stock of the investee. We account for our interest in ARO using the equity method of accounting and only recognize our portion of equity in earnings in our consolidated financial statements. ARO is a variable interest entity; however, we are not the primary beneficiary and therefore do not consolidate ARO.

Reclassification

Certain previously reported amounts have been reclassified to conform to the current year presentation.

Pervasiveness of Estimates

The preparation of financial statements in conformity with GAAP requires us to make certain estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, the related revenues and expenses and disclosures of gain and loss contingencies as of the date of the financial statements. Actual results could differ from those estimates.

Foreign Currency Remeasurement and Translation

Our functional currency is the U.S. dollar. As is customary in the oil and gas industry, a majority of our revenues and expenses are denominated in U.S. dollars; however, a portion of the revenues earned and expenses incurred by certain of our subsidiaries are denominated in currencies other than the U.S. dollar. These transactions are remeasured in U.S. dollars based on a combination of both current and historical exchange rates. Most transaction gains and losses are included in Other, net, in our Consolidated Statements of Operations.  Certain gains and losses from the translation of foreign currency balances of our non-U.S. dollar functional currency subsidiaries are included in Accumulated other comprehensive income on our Consolidated Balance Sheet. Net foreign currency exchange loss was $3.5 million, and gains were $12.2 million, $8.1 million and $13.4 million, and were included in Other, net, in our Consolidated Statements of Operations for the years ended December 31, 2023 and 2022, eight months ended December 31, 2021 (Successor), and four months ended April 30, 2021 (Predecessor), respectively.

81


Cash Equivalents and Short-Term Investments

Highly liquid investments with maturities of three months or less at the date of purchase are considered cash equivalents. Highly liquid investments with maturities of greater than three months but less than one year at the date of purchase are classified as short-term investments.

There were no short-term investments as of December 31, 2023 and 2022. Cash flows from purchases and maturities of short-term investments were classified as investing activities in our Consolidated Statements of Cash Flows for the year ended December 31, 2017. Net loss2022. To mitigate our credit risk, our investments in time deposits have historically been diversified across multiple, high-quality financial institutions.
Property and Equipment

All costs incurred in connection with the acquisition, construction, major enhancement and improvement of Atwoodassets are capitalized, including allocations of interest incurred during periods that our drilling rigs are under construction or undergoing major enhancements and improvements. Costs incurred to place an asset into service are capitalized, including costs related to the initial mobilization of a newbuild drilling rig. Repair and maintenance costs are charged to contract drilling expense in the period in which they are incurred. Upon the sale or retirement of assets, the related cost and accumulated depreciation are removed from the Merger Datebalance sheet, and the resulting gain or loss is included in Other, net in our Consolidated Statements of Operations.

Upon emergence, we elected to change our accounting policies and have identified the significant components of our drilling rigs and ascribed useful lives based on the expected time until the next required overhaul or the end of the expected economic lives of the components.

Our property and equipment is depreciated on a straight-line basis, after allowing for salvage values, over the estimated useful lives of our assets. Drilling rigs and related equipment are depreciated over estimated useful lives ranging from five to 35 years. Buildings and improvements are depreciated over estimated useful lives ranging from 10 to 30 years. Other equipment, including computer and communications hardware and software, is depreciated over estimated useful lives ranging from two to six years.

We evaluate the carrying value of our property and equipment, primarily our drilling rigs, on a quarterly basis to identify events or changes in circumstances ("triggering events") that indicate that the carrying value of such rigs may not be recoverable. For property and equipment used in our operations, recoverability generally is determined by comparing the carrying value of an asset to the expected undiscounted future cash flows of the asset. If the carrying value of an asset is not recoverable, the amount of impairment loss is measured as the difference between the carrying value of the asset and its estimated fair value. Property and equipment held-for-sale is recorded at the lower of net book value or fair value less cost to sell.

We recorded pre-tax, non-cash impairment losses related to long-lived assets of $34.5 million and $756.5 million, in the year ended December 31, 2022 (Successor) and the four months ended April 30, 2021 (Predecessor), respectively. See "Note 7 - Property and Equipment" for additional information on our impairment charges.
Operating Revenues and Expenses
See "Note 4 - Revenue from Contracts with Customers" for information on our accounting policies for revenue recognition and certain operating costs that are deferred and amortized over future periods.
82


Income Taxes

We conduct operations and earn income in numerous countries. Current income taxes are recognized for the amount of taxes payable or refundable based on the laws and income tax rates in the taxing jurisdictions in which operations are conducted and income is earned.

Deferred tax assets and liabilities are recognized for the anticipated future tax effects of temporary differences between the financial statement basis and the tax basis of our assets and liabilities using the enacted tax rates in effect at year-end. A valuation allowance for deferred tax assets is recorded when it is more-likely-than-not that the benefit from the deferred tax asset will not be realized. We do not offset deferred tax assets and deferred tax liabilities attributable to different tax paying jurisdictions.

We operate in certain jurisdictions where tax laws relating to the offshore drilling industry are not well developed and change frequently. Furthermore, we may enter into transactions with affiliates or employ other tax planning strategies that generally are subject to complex tax regulations. As a result of the foregoing, the tax liabilities and assets we recognize in our financial statements may differ from the tax positions taken, or expected to be taken, in our tax returns. Our tax positions are evaluated for recognition as unrecognized tax benefits using a more-likely-than-not threshold, and those requiring recognition are measured as the largest amount of tax benefit that is greater than 50% likely of being realized upon effective settlement with a taxing authority that has full knowledge of all relevant information. Interest and penalties relating to income taxes are included in Current income tax expense in our Consolidated Statements of Operations.

Our drilling rigs frequently move from one taxing jurisdiction to another based on where they are contracted to perform drilling services. The movement of drilling rigs among taxing jurisdictions may involve a transfer of drilling rig ownership among our subsidiaries through an intercompany rig sale. The pre-tax profit resulting from an intercompany rig sale is eliminated from our consolidated financial statements, and the carrying value of a rig sold in an intercompany transaction remains at historical net depreciated cost prior to the transaction. Our consolidated financial statements do not reflect the asset disposition transaction of the selling subsidiary or the asset acquisition transaction of the acquiring subsidiary. The income tax effects resulting from intercompany rig sales are recognized in earnings in the period in which the sale occurs.

In some instances, we may determine that certain temporary differences will not result in a taxable or deductible amount in future years, as it is more-likely-than-not we will commence operations and depart from a given taxing jurisdiction without such temporary differences being recovered or settled. Under these circumstances, no future tax consequences are expected and no deferred taxes are recognized in connection with such operations. We evaluate these determinations on a periodic basis and, in the event our expectations relative to future tax consequences change, the applicable deferred taxes are recognized or derecognized.

We do not provide deferred taxes on the undistributed earnings of certain subsidiaries because our policy and intention is to reinvest such earnings indefinitely. Should we make a distribution from these subsidiaries in the form of dividends or otherwise, we may be subject to additional income taxes.

Share-Based Compensation

We sponsor share-based compensation plans that provide equity compensation to our key employees, officers and non-employee directors. Our 2021 Management Incentive Plan (the “MIP”) allows our board of directors to authorize equity-based grants to be settled in cash, shares or a combination of shares and cash. Compensation expense for time-based equity awards to be settled in shares is measured at fair value on the date of grant and recognized on a straight-line basis over the requisite service period (usually the vesting period). Compensation expense for performance awards is recognized over the requisite service period using the accelerated method and is reduced for forfeited awards in the period in which the forfeitures occur. For our performance awards that cliff vest and require the employee to render service through the vesting date, even though attainment of performance objectives might be earlier, our expense under the accelerated method would be a ratable expense over
83


the vesting period. Equity settled performance awards generally vest at the end of a three-year measurement period based on attainment of performance goals. The estimated probable outcome of attainment of the specified performance goals is based primarily on relative performance over the requisite performance period. Any subsequent changes in this estimate as it relates to performance objectives are recognized as a cumulative adjustment to compensation cost in the period in which the change in estimate occurs, except in the case of objectives based on a market condition, such as our stock price. Compensation cost for awards based on a market performance objective is recognized as long as the requisite service period is completed and will not be reversed even if the market-based objective is never satisfied. Any adjustments to the compensation cost recognized in our Consolidated Statements of Operations for awards that are forfeited are recognized in the period in which the forfeitures occur. See "Note 10 - Share Based Compensation" for additional information on our share-based compensation.

Pension and Other Post-retirement Benefit Plans

We measure our actuarially determined obligations and related costs for our defined benefit pension and other post-retirement plans, retiree life and medical supplemental plan benefits by applying assumptions, the most significant of which include long-term rate of return on plan assets, discount rates and mortality rates. For the long-term rate of return, we develop our assumptions regarding the expected rate of return on plan assets based on historical experience and projected long-term investment returns, and we weight the assumptions based on each plan's asset allocation. For the discount rate, we base our assumptions on a yield curve approach. Actual results may differ from the assumptions included in these calculations. If gains or losses exceed 10% of the greater of the plan assets or plan liabilities, we amortize such gains or losses into income over either the period of expected future service of active participants, or over the expected average remaining lifetime of all participants. We recognize gains or losses related to plan curtailments at the date the plan amendment or termination is adopted which may precede the effective date.
Fair Value Measurements

We measure certain of our assets and liabilities based on a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy assigns the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities ("Level 1") and the lowest priority to unobservable inputs ("Level 3"). Level 2 measurements represent inputs that are observable for similar assets or liabilities, either directly or indirectly, other than quoted prices included within Level 1.  See "Note 6 - Fair Value Measurements" for additional information on the fair value measurement of certain of our assets and liabilities.

Noncontrolling Interests

Third parties hold a noncontrolling ownership interest in certain of our non-U.S. subsidiaries. Noncontrolling interests are classified as equity on our Consolidated Balance Sheet, and net income attributable to noncontrolling interests is presented separately in our Consolidated Statements of Operations. All income attributable to noncontrolling interest was $70.1from continuing operations.

Cancellation of Predecessor Equity and Issuance of Warrants

On the Effective Date and pursuant to the plan of reorganization, the Legacy Valaris Class A ordinary shares were cancelled and all agreements, instruments and other documents evidencing, relating or otherwise connected with any of Legacy Valaris' equity interests outstanding prior to the Effective Date, including all equity-based awards, were also cancelled. Also, in accordance with the plan of reorganization, the Company issued 5.6 million inclusivewarrants (the "Warrants") to the former holders of integration costsLegacy Valaris' equity to purchase common shares of $27.9 million,Valaris Limited with a nominal value of $0.01 per share (the "Common Shares"). The Warrants are exercisable for one Common Share per Warrant at an initial exercise price of $131.88 per Warrant, in each case as may be adjusted from time to time pursuant to the applicable warrant agreement. The Warrants are exercisable for a period of seven years and will expire on April 29, 2028.
84



Earnings Per Share

Basic earnings (loss) per share is computed by dividing net income (loss) available to common shareholders by the weighted-average number of common shares outstanding during the period. Basic and diluted earnings per share ("EPS") for the Predecessor was calculated in accordance with the two-class method. Weighted-average shares outstanding used in our computation of diluted EPS is calculated using the treasury stock method and for the Successor includes the effect of all potentially dilutive stock equivalents, including warrants, restricted stock unit awards and performance stock unit awards and for the Predecessor included the effect of all potentially dilutive stock options and excluded non-vested shares.

The following table is a reconciliation of the weighted-average shares used in our basic and diluted EPS computations for the years ended December 31, 2023 and 2022, eight months ended December 31, 2021 (Successor), and four months ended April 30, 2021 (Predecessor) (in millions):

Anti-dilutive share awards totaling 147,000 and 192,000 were excluded from the computation of diluted EPS for the year ended December 31, 2017.2023 and 2022 (Successor), respectively.




Consideration

    As a result of the Merger, Atwood shareholders received 1.60 Ensco Class A Ordinary shares for each share of Atwood common stock, representing a value of $9.33 per share of Atwood common stock based on a closing price of $5.83 per Class A ordinary share on October 5, 2017, the last trading day before the Merger Date. Total consideration delivered in the Merger consisted of 132.2 million of our Class A ordinary shares and $11.1 million of cash in settlement of certain share-based payment awards. The total aggregate value of consideration transferred was $781.8 million. Additionally, upon closing of the Merger, we utilized cash acquired of $445.4 million and cash on handDue to extinguish Atwood's revolving credit facility, outstanding senior notes and accrued interest totaling $1.3 billion. The estimated fair values assigned to assets acquired net of liabilities assumed exceeded the consideration transferred, resulting in a bargain purchase gain of $140.2 million that was recognized during the fourth quarter.

Assets Acquired and Liabilities Assumed
Assets acquired and liabilities assumed in the Merger have been recorded at their estimated fair values as of the Merger Date under the acquisition method of accounting. When the fair value of the net assets acquired exceeds the consideration transferred in an acquisition, the difference is recorded as a bargain purchase gain in the period in which the transaction occurs. We have not finalized the fair values of assets acquiredloss position, anti-dilutive shares totaling 600,000 and liabilities assumed; therefore, the fair value estimates set forth below are subject to adjustment during a one year measurement period subsequent to the Merger Date. The estimated fair values of certain assets and liabilities including inventory, long-lived assets and contingencies require judgments and assumptions that increase the likelihood that adjustments may be made to these estimates during the measurement period, and those adjustments could be material.

The provisional amounts for assets acquired and liabilities assumed are based on preliminary estimates of their fair values as of the Merger Date and were as follows (in millions):
 Estimated Fair Value
Assets: 
Cash and cash equivalents(1)
$445.4
Accounts receivable(2)

Other liabilities118.7
Net assets acquired2,227.9
Less: 
Merger consideration(781.8)

Bargain purchase gain$140.2

(1) Upon closing of the Merger, we utilized acquired cash of $445.4 million and cash on hand from the liquidation of short-term investments to repay Atwood's debt and accrued interest of $1.3 billion.
(2) Gross contractual amounts receivable totaled $64.7 million as of the Merger Date.



Bargain Purchase Gain

The estimated fair values assigned to assets acquired net of liabilities assumed exceeded the consideration transferred, resulting in a bargain purchase gain primarily due to depressed offshore drilling company valuations. Market capitalizations across the offshore drilling industry have declined significantly since mid-2014 due to the decline in commodity prices and the related imbalance of supply and demand for drilling rigs. The resulting bargain purchase gain was further driven by the decline in our share price from $6.70 to $5.83 between the last trading day prior to the announcement of the Merger and the Merger Date. The gain was included in other, net, in our consolidated statement of operations300,000, for the yeareight months ended December 31, 2017.2021 (Successor) and the four months ended April 30, 2021 (Predecessor), respectively, were excluded from the computation of diluted EPS.

Merger-Related Costs

Merger-related costs were expensedWe have 5,470,950 Warrants outstanding as incurred and consisted of various advisory, legal, accounting, valuation and other professional or consulting fees totaling $19.4 millionDecember 31, 2023 which are exercisable for one Common Share per Warrant at an initial exercise price of $131.88 per Warrant. The exercise of these Warrants into Common Shares would have a dilutive effect to the holdings of Valaris Limited's existing shareholders.

Property and Equipment


Concurrent with our emergence from bankruptcy, we applied fresh start accounting and adjusted the carrying value of our drilling rigs to estimated fair value. See "Note 3 - Fresh Start Accounting" to our consolidated financial statements included in "Item 8. Financial Statements and Supplementary Data" for more information. As of December 31, 2023, the carrying value of our property and equipment totaled $1.6 billion, which represented 38% of total assets. This carrying value reflects the application of our property and equipment accounting policies, which incorporate our estimates, judgments and assumptions relative to the capitalized costs, useful lives and salvage values of our rigs.
We develop and apply property and equipment accounting policies that are designed to appropriately and consistently capitalize those costs incurred to enhance, improve and extend the useful lives of our assets and expense those costs incurred to repair or maintain the existing condition or useful lives of our assets. The development and application of such policies requires estimates, judgments and assumptions relative to the nature of, and benefits from, expenditures on our assets. We establish property and equipment accounting policies that are designed to depreciate our assets over their estimated useful lives.

Upon emergence, we elected to change our accounting policies and have identified the significant components of our drilling rigs and ascribed useful lives based on the expected time until the next required overhaul or the end of the expected economic lives of the components.

The judgments and assumptions used in determining the next overhaul or the economic lives of the components of our property and equipment reflect both historical experience and expectations regarding future operations, utilization and performance of our assets. The use of different estimates, judgments and assumptions in the establishment of our property and equipment accounting policies, especially those involving the useful lives of the significant components our rigs, would likely result in materially different asset carrying values and operating results.
The useful lives of our drilling rig components are difficult to estimate due to a variety of factors, including technological advances that impact the methods or cost of oil and natural gas exploration and development, changes in market or economic conditions and changes in laws or regulations affecting the drilling industry. We evaluate the remaining useful lives of our rig components on a periodic basis, considering operating condition, functional capability and market and economic factors.

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

Our fleet of 18 floater rigs represented 62% of the gross cost and 63% of the net carrying amount of our depreciable property and equipment as of December 31, 2023. Our fleet of 35 jackup rigs represented 34% of the gross cost and 33% of the net carrying amount of our depreciable property and equipment as of December 31, 2023. 

Income Taxes
We conduct operations and earn income in numerous countries and are subject to the laws of numerous tax jurisdictions. As of December 31, 2023, our Consolidated Balance Sheet included a $825.2 million net deferred income tax asset, a $36.6 million liability for income taxes currently payable and a $224.0 million liability for unrecognized tax benefits, inclusive of interest and penalties.

The carrying values of deferred income tax assets and liabilities reflect the application of our income tax accounting policies and are based on estimates, judgments and assumptions regarding future operating results and levels of taxable income. Carryforwards and tax credits are assessed for realization as a reduction of future taxable income by using a more-likely-than-not determination. We do not offset deferred tax assets and deferred tax liabilities attributable to different tax paying jurisdictions.

We do not provide deferred taxes on the undistributed earnings of certain subsidiaries because our policy and intention is to reinvest such earnings indefinitely. Should we make a distribution from these subsidiaries in the form of dividends or otherwise, we may be subject to additional income taxes.

The carrying values of liabilities for income taxes currently payable and unrecognized tax benefits are based on our interpretation of applicable tax laws and incorporate estimates, judgments and assumptions regarding the use of tax planning strategies in various taxing jurisdictions. The use of different estimates, judgments and assumptions in connection with accounting for income taxes, especially those involving the deployment of tax planning strategies, may result in materially different carrying values of income tax assets and liabilities and operating results.

We operate in several jurisdictions where tax laws relating to the offshore drilling industry are not well developed. In jurisdictions where available statutory law and regulations are incomplete or underdeveloped, we obtain professional guidance and consider existing industry practices before utilizing tax planning strategies and meeting our tax obligations. Our tax positions are evaluated for recognition using a more-likely-than-not threshold, and those tax positions requiring recognition are measured as the largest amount of tax benefit that is greater than 50% likely of being realized upon effective settlement with a taxing authority that has full knowledge of all relevant information.

Tax returns are routinely subject to audit in most jurisdictions and tax liabilities occasionally are finalized through a negotiation process. In some jurisdictions, income tax payments may be required before a final income tax obligation is determined in order to avoid significant penalties and/or interest. While we historically have not experienced significant adjustments to previously recognized tax assets and liabilities as a result of finalizing tax returns, there can be no assurance that significant adjustments will not arise in the future. In addition, there are several factors that could cause the future level of uncertainty relating to our tax liabilities to increase, including the following:

During recent years, the number of tax jurisdictions in which we conduct operations has increased.

In order to utilize tax planning strategies and conduct operations efficiently, our subsidiaries frequently enter into transactions with affiliates that are generally subject to complex tax regulations and are frequently reviewed and challenged by tax authorities.
68



We may conduct future operations in certain tax jurisdictions where tax laws are not well developed, and it may be difficult to secure adequate professional guidance.

Tax laws, regulations, agreements, treaties and the administrative practices and precedents of tax authorities change frequently, requiring us to modify existing tax strategies to conform to such changes.

Pension and Other Postretirement Benefits

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, 2023, included (1) a weighted average discount rate of 4.97% to determine pension benefit obligations, (2) a weighted average discount rate of 5.21% to determine net periodic pension cost and (3) an expected long-term rate of return on pension plan assets of 7.10% to determine net periodic pension cost. The assumed discount rate is based upon the average yield for either Moody’s or Standard & Poor'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.

Using our key assumptions at December 31, 2023, a one-percentage-point decrease in the assumed discount rate would increase our recorded pension and other postretirement benefit liabilities by approximately $60.1 million, while a one-percentage-point decrease (increase) in the expected long-term rate of return on plan assets would increase (decrease) annual net benefits cost by approximately $4.4 million. 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 decreased to 6.88% at December 31, 2023 from 7.10% at December 31, 2022. See "Note 11 - Pension and Other Post Retirement Benefits" to our consolidated financial statements included in "Item 8. Financial Statements and Supplementary Data" for information on our pension and other postretirement benefit plans.

MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) or 15d-15(f). Our internal control over financial reporting system is designed to provide reasonable assurance as to the reliability of our financial reporting and the preparation and presentation of consolidated financial statements in accordance with accounting principles generally accepted in the United States, as well as to safeguard assets from unauthorized use or disposition. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Under the supervision and with the participation of management, including the Chief Executive Officer and Chief Financial Officer, we have conducted an evaluation of the effectiveness of our internal control over financial reporting based on the criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on this evaluation, we have concluded that our internal control over financial reporting is effective as of December 31, 2023 to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.

KPMG LLP, the independent registered public accounting firm who audited our consolidated financial statements, has issued an audit report on our internal control over financial reporting. KPMG LLP's audit report on our internal control over financial reporting is included herein.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders
Valaris Limited:
Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Valaris Limited and subsidiaries (the Company) as of December 31, 2023 and 2022, the related consolidated statements of operations, comprehensive income (loss), and cash flows for each of the years in the two-year period ended December 31, 2023 and for the period from May 1, 2021 to December 31, 2021 (Successor periods) and for the period from January 1, 2021 to April 30, 2021 (Predecessor period), and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for Successor and Predecessor periods, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated February 22, 2024 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

Basis of Presentation

As discussed in Note 1 to the consolidated financial statements, on March 3, 2021, the Bankruptcy Court for the Southern District of Texas entered an order confirming the Company’s plan for reorganization under Chapter 11, which became effective on April 30, 2021. Accordingly, the accompanying consolidated financial statements as of December 31, 2023 and 2022 and for the Successor periods have been prepared in conformity with Accounting Standards Codification 852, Reorganization, with the Company’s assets, liabilities, and capital structure having carrying amounts not comparable to prior years.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

71


Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Income tax positions pertaining to certain tax transactions

As discussed in Notes 1 and 12 to the consolidated financial statements, the Company evaluated the income tax effect of certain transactions which often requires local country tax expertise and judgment. This requires the Company to interpret complex tax laws in multiple jurisdictions to assess whether its tax positions have a more than 50 percent likelihood of being sustained with the taxing authorities.

We identified the assessment of income tax positions pertaining to certain tax transactions as a critical audit matter. Complex auditor judgment was required to evaluate the Company’s assessment that certain tax positions have a more than 50 percent likelihood of being sustained with the taxing authorities. In addition, specialized skills and knowledge were required to evaluate the Company’s interpretation of tax laws in the applicable jurisdictions.

The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls over the Company’s income tax process. This included controls related to the interpretation of tax laws applicable to certain transactions and the assessment that tax positions pertaining to those transactions have a more than 50 percent likelihood of being sustained with taxing authorities. We involved tax professionals with specialized skills and knowledge, who assisted on evaluating the Company’s interpretation of local tax laws and assessment of whether tax positions had a greater than 50 percent likelihood of being sustained with taxing authorities.

Realizability of certain deferred tax assets

As discussed in Notes 1 and 12 to the consolidated financial statements, the Company recognizes a valuation allowance for deferred tax assets if, based on the weight of all available evidence, it is more-likely-than-not that the benefit from the deferred tax asset will not be realized. The realization of deferred tax assets is dependent upon generating sufficient taxable income during future periods in the jurisdictions it operates. As of December 31, 2023, the Company had recorded a valuation allowance of $4.2 billion on deferred tax assets. During the year ended December 31, 2023, the Company released $799.5 million of the valuation allowance recognized related to deferred tax assets.

We identified the evaluation of the realizability of certain deferred tax assets as a critical audit matter. A high degree of subjective auditor judgment was required due to (1) the significant judgment made by the Company in assessing the ability to realize the deferred tax assets and whether a valuation allowance was necessary considering the availability of forecasted income and (2) the subjective nature of the sources of possible future income used in the Company's assessment and the key assumptions used in the estimation of such future income, specifically forecasted revenue, contract drilling expenses and shore-based expenses.

72


The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls related to the Company's process to assess the realizability of certain deferred tax assets, including controls over the key assumptions used in the determination of forecasted income. We evaluated available positive and negative evidence used in the Company's assessment of whether certain deferred tax assets were more like than not to be realized in the future. We evaluated the reasonableness of the revenue, contract drilling expenses and shore-based expenses assumptions used in determining forecasted income for consistency with historical amounts, economic trends and industry data. We involved tax professionals with specialized skills and knowledge, who assisted in the application of tax laws in the performance of these procedures.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


To the Board of Directors and Shareholders
Valaris Limited:

Opinion on Internal Control Over Financial Reporting
We have audited Valaris Limited and subsidiaries’ (the Company) internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2023 and 2022, the related consolidated statements of operations, comprehensive income (loss), and cash flows for each of the years in the two-year period ended December 31, 2023 and for the period from May 1, 2021 to December 31, 2021 (Successor periods) and for the period from January 1, 2021 to April 30, 2021 (Predecessor period), and the related notes (collectively, the consolidated financial statements), and our report dated February 22, 2024 expressed an unqualified opinion on those consolidated financial statements.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

74


Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

VALARIS LIMITED AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
1.  DESCRIPTION OF THE BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Business
We are a leading provider of offshore contract drilling services to the international oil and gas industry with operations in almost every major offshore market across six continents. We own the world's largest offshore drilling rig fleet, including one of the newest ultra-deepwater fleets in the industry and a leading premium jackup fleet. We currently own 53 rigs, including 13 drillships, four dynamically positioned semisubmersible rigs, one moored semisubmersible rig, 35 jackup rigs and a 50% equity interest in Saudi Aramco Rowan Offshore Drilling Company ("ARO"), our 50/50 unconsolidated joint venture with Saudi Aramco, which owns an additional eight rigs.

Our customers include many of the leading international and government-owned oil and gas companies, in addition to many independent operators. We are among the most geographically diverse offshore drilling companies with global operations. The markets in which we operate include the Gulf of Mexico, South America, the North Sea, the Middle East, Africa and Asia Pacific.

We provide drilling services on a day rate contract basis. Under day rate contracts, we provide an integrated service that includes the provision of a drilling rig and rig crews for which we receive a daily rate that may vary between the full rate and zero rate throughout the duration of the contractual term, depending on the operations of the rig. We also may receive lump-sum fees or similar compensation for the mobilization, demobilization and capital upgrades of our rigs. 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.

Chapter 11 Cases

On August 19, 2020 (the “Petition Date”), Valaris plc (“Legacy Valaris” or “Predecessor”) and certain of its direct and indirect subsidiaries (collectively, the “Debtors”) filed voluntary petitions for reorganization under chapter 11 of the United States Bankruptcy Code ("Bankruptcy Code") in the Bankruptcy Court for the Southern District of Texas (the "Bankruptcy Court") The Debtors obtained joint administration of their chapter 11 cases under the caption In re Valaris plc, et al., Case No. 20-34114 (MI) (the “Chapter 11 Cases”).

In connection with the Chapter 11 Cases, on and prior to April 30, 2021 (the "Effective Date"), Legacy Valaris effectuated certain restructuring transactions, pursuant to which the successor company, Valaris, was formed and, through a series of transactions, Legacy Valaris transferred to a subsidiary of Valaris substantially all of the subsidiaries, and other assets, of Legacy Valaris.

References to the financial position and results of operations of the "Successor" or "Successor Company" relate to the financial position and results of operations of the Company after the Effective Date. References to the financial position and results of operations of the "Predecessor" or "Predecessor Company" refer to the financial position and results of operations of Legacy Valaris on and prior to the Effective Date. References to the “Company,” “we,” “us” or “our” in this Annual Report are to Valaris Limited, together with its consolidated subsidiaries, when referring to periods following the Effective Date, and to Legacy Valaris, together with its consolidated subsidiaries, when referring to periods prior to and including Effective Date.

SeeNote 2 – Chapter 11 Proceedings” for additional details regarding the Chapter 11 Cases.

Fresh Start Accounting

On the Effective Date, the Debtors emerged from the Chapter 11 Cases. Upon emergence from the Chapter 11 Cases, we qualified for and adopted fresh start accounting. The application of fresh start accounting resulted in a new basis of accounting, and the Company became a new entity for financial reporting purposes. Accordingly, our financial statements and notes after the Effective Date are not comparable to our financial statements and notes on and prior to that date. Furthermore, the consolidated financial statements and notes have been presented with a black line division to delineate the lack of comparability between the Predecessor and Successor.

See “Note 2 – Chapter 11 Proceedings” and “Note 3 - Fresh Start Accounting” for additional details regarding the Chapter 11 Cases and fresh start accounting.

Accounting Policies

Principles of Consolidation

The accompanying consolidated financial statements include the accounts of Valaris Limited, those of our wholly-owned subsidiaries and entities in which we hold a controlling financial interest. All intercompany accounts and transactions have been eliminated. Investments in operating entities in which we have the ability to exercise significant influence, but where we do not control operating and financial policies are accounted for using the equity method. Significant influence generally exists if we have an ownership interest representing between 20% and 50% of the voting stock of the investee. We account for our interest in ARO using the equity method of accounting and only recognize our portion of equity in earnings in our consolidated financial statements. ARO is a variable interest entity; however, we are not the primary beneficiary and therefore do not consolidate ARO.

Reclassification

Certain previously reported amounts have been reclassified to conform to the current year presentation.

Pervasiveness of Estimates

The preparation of financial statements in conformity with GAAP requires us to make certain estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, the related revenues and expenses and disclosures of gain and loss contingencies as of the date of the financial statements. Actual results could differ from those estimates.

Foreign Currency Remeasurement and Translation

Our functional currency is the U.S. dollar. As is customary in the oil and gas industry, a majority of our revenues and expenses are denominated in U.S. dollars; however, a portion of the revenues earned and expenses incurred by certain of our subsidiaries are denominated in currencies other than the U.S. dollar. These transactions are remeasured in U.S. dollars based on a combination of both current and historical exchange rates. Most transaction gains and losses are included in Other, net, in our Consolidated Statements of Operations.  Certain gains and losses from the translation of foreign currency balances of our non-U.S. dollar functional currency subsidiaries are included in Accumulated other comprehensive income on our Consolidated Balance Sheet. Net foreign currency exchange loss was $3.5 million, and gains were $12.2 million, $8.1 million and $13.4 million, and were included in Other, net, in our Consolidated Statements of Operations for the years ended December 31, 2023 and 2022, eight months ended December 31, 2021 (Successor), and four months ended April 30, 2021 (Predecessor), respectively.

81


Cash Equivalents and Short-Term Investments

Highly liquid investments with maturities of three months or less at the date of purchase are considered cash equivalents. Highly liquid investments with maturities of greater than three months but less than one year at the date of purchase are classified as short-term investments.

There were no short-term investments as of December 31, 2023 and 2022. Cash flows from purchases and maturities of short-term investments were classified as investing activities in our Consolidated Statements of Cash Flows for the year ended December 31, 2022. To mitigate our credit risk, our investments in time deposits have historically been diversified across multiple, high-quality financial institutions.
Property and Equipment

All costs incurred in connection with the Merger consisted primarilyacquisition, construction, major enhancement and improvement of assets are capitalized, including allocations of interest incurred during periods that our drilling rigs are under construction or undergoing major enhancements and improvements. Costs incurred to place an asset into service are capitalized, including costs related to the initial mobilization of a newbuild drilling rig. Repair and maintenance costs are charged to contract drilling expense in the period in which they are incurred. Upon the sale or retirement of assets, the related cost and accumulated depreciation are removed from the balance sheet, and the resulting gain or loss is included in Other, net in our Consolidated Statements of Operations.

Upon emergence, we elected to change our accounting policies and have identified the significant components of our drilling rigs and ascribed useful lives based on the expected time until the next required overhaul or the end of the expected economic lives of the components.

Our property and equipment is depreciated on a straight-line basis, after allowing for salvage values, over the estimated useful lives of our assets. Drilling rigs and related equipment are depreciated over estimated useful lives ranging from five to 35 years. Buildings and improvements are depreciated over estimated useful lives ranging from 10 to 30 years. Other equipment, including four drillships (twocomputer and communications hardware and software, is depreciated over estimated useful lives ranging from two to six years.

We evaluate the carrying value of which are under construction), two semisubmersible rigs and five jackup rigs.  We recordedour property and equipment, primarily our drilling rigs, on a quarterly basis to identify events or changes in circumstances ("triggering events") that indicate that the carrying value of such rigs may not be recoverable. For property and equipment used in our operations, recoverability generally is determined by comparing the carrying value of an asset to the expected undiscounted future cash flows of the asset. If the carrying value of an asset is not recoverable, the amount of impairment loss is measured as the difference between the carrying value of the asset and its estimated fair value. Property and equipment held-for-sale is recorded at the lower of net book value or fair value less cost to sell.

We recorded pre-tax, non-cash impairment losses related to long-lived assets of $34.5 million and $756.5 million, in the year ended December 31, 2022 (Successor) and the four months ended April 30, 2021 (Predecessor), respectively. See "Note 7 - Property and Equipment" for additional information on our impairment charges.
Operating Revenues and Expenses
See "Note 4 - Revenue from Contracts with Customers" for information on our accounting policies for revenue recognition and certain operating costs that are deferred and amortized over future periods.
82


Income Taxes

We conduct operations and earn income in numerous countries. Current income taxes are recognized for the amount of taxes payable or refundable based on the laws and income tax rates in the taxing jurisdictions in which operations are conducted and income is earned.

Deferred tax assets and liabilities are recognized for the anticipated future tax effects of temporary differences between the financial statement basis and the tax basis of our assets and liabilities using the enacted tax rates in effect at year-end. A valuation allowance for deferred tax assets is recorded when it is more-likely-than-not that the benefit from the deferred tax asset will not be realized. We do not offset deferred tax assets and deferred tax liabilities attributable to different tax paying jurisdictions.

We operate in certain jurisdictions where tax laws relating to the offshore drilling industry are not well developed and change frequently. Furthermore, we may enter into transactions with affiliates or employ other tax planning strategies that generally are subject to complex tax regulations. As a result of the foregoing, the tax liabilities and assets we recognize in our financial statements may differ from the tax positions taken, or expected to be taken, in our tax returns. Our tax positions are evaluated for recognition as unrecognized tax benefits using a more-likely-than-not threshold, and those requiring recognition are measured as the largest amount of tax benefit that is greater than 50% likely of being realized upon effective settlement with a taxing authority that has full knowledge of all relevant information. Interest and penalties relating to income taxes are included in Current income tax expense in our Consolidated Statements of Operations.

Our drilling rigs frequently move from one taxing jurisdiction to another based on where they are contracted to perform drilling services. The movement of drilling rigs among taxing jurisdictions may involve a transfer of drilling rig ownership among our subsidiaries through an intercompany rig sale. The pre-tax profit resulting from an intercompany rig sale is eliminated from our consolidated financial statements, and the carrying value of a rig sold in an intercompany transaction remains at historical net depreciated cost prior to the transaction. Our consolidated financial statements do not reflect the asset disposition transaction of the selling subsidiary or the asset acquisition transaction of the acquiring subsidiary. The income tax effects resulting from intercompany rig sales are recognized in earnings in the period in which the sale occurs.

In some instances, we may determine that certain temporary differences will not result in a taxable or deductible amount in future years, as it is more-likely-than-not we will commence operations and depart from a given taxing jurisdiction without such temporary differences being recovered or settled. Under these circumstances, no future tax consequences are expected and no deferred taxes are recognized in connection with such operations. We evaluate these determinations on a periodic basis and, in the event our expectations relative to future tax consequences change, the applicable deferred taxes are recognized or derecognized.

We do not provide deferred taxes on the undistributed earnings of certain subsidiaries because our policy and intention is to reinvest such earnings indefinitely. Should we make a distribution from these subsidiaries in the form of dividends or otherwise, we may be subject to additional income taxes.

Share-Based Compensation

We sponsor share-based compensation plans that provide equity compensation to our key employees, officers and non-employee directors. Our 2021 Management Incentive Plan (the “MIP”) allows our board of directors to authorize equity-based grants to be settled in cash, shares or a combination of shares and cash. Compensation expense for time-based equity awards to be settled in shares is measured at fair value on the date of grant and recognized on a straight-line basis over the requisite service period (usually the vesting period). Compensation expense for performance awards is recognized over the requisite service period using the accelerated method and is reduced for forfeited awards in the period in which the forfeitures occur. For our performance awards that cliff vest and require the employee to render service through the vesting date, even though attainment of performance objectives might be earlier, our expense under the accelerated method would be a ratable expense over
83


the vesting period. Equity settled performance awards generally vest at the end of a three-year measurement period based on attainment of performance goals. The estimated probable outcome of attainment of the specified performance goals is based primarily on relative performance over the requisite performance period. Any subsequent changes in this estimate as it relates to performance objectives are recognized as a cumulative adjustment to compensation cost in the period in which the change in estimate occurs, except in the case of objectives based on a market condition, such as our stock price. Compensation cost for awards based on a market performance objective is recognized as long as the requisite service period is completed and will not be reversed even if the market-based objective is never satisfied. Any adjustments to the compensation cost recognized in our Consolidated Statements of Operations for awards that are forfeited are recognized in the period in which the forfeitures occur. See "Note 10 - Share Based Compensation" for additional information on our share-based compensation.

Pension and Other Post-retirement Benefit Plans

We measure our actuarially determined obligations and related costs for our defined benefit pension and other post-retirement plans, retiree life and medical supplemental plan benefits by applying assumptions, the most significant of which include long-term rate of return on plan assets, discount rates and mortality rates. For the long-term rate of return, we develop our assumptions regarding the expected rate of return on plan assets based on historical experience and projected long-term investment returns, and we weight the assumptions based on each plan's asset allocation. For the discount rate, we base our assumptions on a yield curve approach. Actual results may differ from the assumptions included in these calculations. If gains or losses exceed 10% of the greater of the plan assets or plan liabilities, we amortize such gains or losses into income over either the period of expected future service of active participants, or over the expected average remaining lifetime of all participants. We recognize gains or losses related to plan curtailments at the date the plan amendment or termination is adopted which may precede the effective date.
Fair Value Measurements

We measure certain of our assets and liabilities based on a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy assigns the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities ("Level 1") and the lowest priority to unobservable inputs ("Level 3"). Level 2 measurements represent inputs that are observable for similar assets or liabilities, either directly or indirectly, other than quoted prices included within Level 1.  See "Note 6 - Fair Value Measurements" for additional information on the fair value measurement of certain of our assets and liabilities.

Noncontrolling Interests

Third parties hold a noncontrolling ownership interest in certain of our non-U.S. subsidiaries. Noncontrolling interests are classified as equity on our Consolidated Balance Sheet, and net income attributable to noncontrolling interests is presented separately in our Consolidated Statements of Operations. All income attributable to noncontrolling interest was from continuing operations.

Cancellation of Predecessor Equity and Issuance of Warrants

On the Effective Date and pursuant to the plan of reorganization, the Legacy Valaris Class A ordinary shares were cancelled and all agreements, instruments and other documents evidencing, relating or otherwise connected with any of Legacy Valaris' equity interests outstanding prior to the Effective Date, including all equity-based awards, were also cancelled. Also, in accordance with the plan of reorganization, the Company issued 5.6 million warrants (the "Warrants") to the former holders of Legacy Valaris' equity to purchase common shares of Valaris Limited with a nominal value of $0.01 per share (the "Common Shares"). The Warrants are exercisable for one Common Share per Warrant at an initial exercise price of $131.88 per Warrant, in each case as may be adjusted from time to time pursuant to the applicable warrant agreement. The Warrants are exercisable for a period of seven years and will expire on April 29, 2028.
84



Earnings Per Share

Basic earnings (loss) per share is computed by dividing net income (loss) available to common shareholders by the weighted-average number of common shares outstanding during the period. Basic and diluted earnings per share ("EPS") for the Predecessor was calculated in accordance with the two-class method. Weighted-average shares outstanding used in our computation of diluted EPS is calculated using the treasury stock method and for the Successor includes the effect of all potentially dilutive stock equivalents, including warrants, restricted stock unit awards and performance stock unit awards and for the Predecessor included the effect of all potentially dilutive stock options and excluded non-vested shares.

The following table is a reconciliation of the weighted-average shares used in our basic and diluted EPS computations for the years ended December 31, 2023 and 2022, eight months ended December 31, 2021 (Successor), and four months ended April 30, 2021 (Predecessor) (in millions):

SuccessorPredecessor
 Year Ended December 31, 2023Year Ended December 31, 2022Eight Months Ended December 31, 2021Four Months Ended April 30, 2021
Income (loss) attributable to our shares$865.4 $176.5 $(27.4)$(4,467.0)
Weighted average shares outstanding:
Basic74.1 75.1 75.0 199.6 
Effect of stock equivalents1.1 0.5 — — 
Diluted75.2 75.6 75.0 199.6 

Anti-dilutive share awards totaling 147,000 and 192,000 were excluded from the computation of diluted EPS for the year ended December 31, 2023 and 2022 (Successor), respectively.

Due to the net loss position, anti-dilutive shares totaling 600,000 and 300,000, for the eight months ended December 31, 2021 (Successor) and the four months ended April 30, 2021 (Predecessor), respectively, were excluded from the computation of diluted EPS.
We have 5,470,950 Warrants outstanding as of December 31, 2023 which are exercisable for one Common Share per Warrant at an initial exercise price of $131.88 per Warrant. The exercise of these Warrants into Common Shares would have a dilutive effect to the holdings of Valaris Limited's existing shareholders. These Warrants are anti-dilutive for all periods presented for the Successor.

The Predecessor previously had convertible senior notes due 2024 (the "2024 Convertible Notes") for which we had the option to settle in cash, shares or a combination thereof for the aggregate amount due upon conversion. On the Effective Date, pursuant to the plan of reorganization, all outstanding obligations under the 2024 Convertible Notes were cancelled and the holders thereunder received the treatment as set forth in the plan of reorganization. However, if the Legacy Valaris average share price had exceeded the exchange price during a respective predecessor reporting period, an assumed number of shares required to settle the conversion obligation in excess of the principal amount would have been included in our denominator for the computation of diluted EPS using the treasury stock method. The Legacy Valaris average share price did not exceed the exchange price during the four months ended April 30, 2021 (Predecessor).

New Accounting Pronouncements

Recently adopted accounting pronouncements

Business Combinations - In October 2021, the FASB issued ASU No. 2021-08, “Accounting for Contract Assets and Contract Liabilities from Contracts with Customers” (Update 2021-08”). ASU No. 2021-08 requires an entity (acquirer) to recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606 and provides practical expedients for acquirers when recognizing and measuring acquired contract assets and contract liabilities from revenue contracts in a business combination. The amendments also apply to contract assets and contract liabilities from other contracts to which the provisions of Topic 606 apply, such as contract liabilities for the sale of nonfinancial assets within the scope of Subtopic 610-20, Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets. The FASB issued the update to improve the accounting for acquired revenue contracts with customers in a business combination. Update 2021-08 is effective for fiscal years beginning after December 15, 2022, and interim periods within those fiscal years, with early adoption permitted. We adopted Update 2021-08 effective January 1, 2023 with no material impact to our financial statements upon adoption.

Reference Rate Reform - In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting ("Update 2020-04"), which provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments in Update 2020-04 apply only to contracts, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The provisions in Update 2020-04 were effective upon issuance and could be applied prospectively to contract modifications made through December 31, 2022. In December 2022, the FASB issued ASU No. 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848, to extend the temporary accounting rules under Topic 848 from December 31, 2022, to December 31, 2024. Our long-term notes receivable from ARO (the "Notes Receivable from ARO"), has generated interest income on a LIBOR-based rate since inception of the note. In 2023, we amended the terms of the Notes Receivable from ARO whereby beginning in 2024, interest income is calculated on a Secured Overnight Financing Rate ("SOFR") based rate. The application of Update 2020-04 and ASU No. 2022-06 on this contract modification and the change in reference rates did not have a material impact on our consolidated financial statements.

Accounting pronouncements to be adopted

Improvements to Reportable Segment Disclosures - In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures ("Update 2023-07"), which expands reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The amendments in Update 2023-07 require that a public entity disclose, on an annual and interim basis, significant segment expenses that are regularly provided to an entity's chief operating decision maker ("CODM"), a description of other segment items by reportable segment, and any additional measures of a segment's profit or loss used by the CODM when deciding how to allocate resources. Annual disclosures are required for fiscal years beginning after December 15, 2023 and interim disclosures are required for periods within fiscal years beginning after December 15, 2024. Retrospective application is required for all prior periods presented, and early adoption is permitted. We are currently assessing the impact of the requirements on our consolidated financial statements and disclosures.

86


Improvements to Income Tax Disclosures - In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures ("Update 2023-09"), which expands income tax disclosure requirements to include additional information related to the rate reconciliation of our effective tax rates to statutory rates as well as additional disaggregation of taxes paid. The amendments in Update 2023-09 also remove disclosures related to certain unrecognized tax benefits and deferred taxes. Update 2023-09 is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The amendments are required to be applied on a prospective basis, with an option to apply the guidance retrospectively. We are currently assessing the impact of the requirements on our consolidated financial statements and disclosures.

With the exception of the updated standards discussed above, there have been no accounting pronouncements issued and not yet effective that have significance, or potential significance, to our consolidated financial statements.
2. CHAPTER 11 PROCEEDINGS

Chapter 11 Cases and Emergence from Chapter 11

On the Petition Date, the Debtors filed voluntary petitions for reorganization under chapter 11 of the Bankruptcy Code in the Bankruptcy Court.

See "Note 10 - Share Based Compensation" for more information on awards granted under the MIP after the Effective date.

88


Liabilities Subject to Compromise

Prior to the Effective Date, liabilities subject to compromise were comprised primarily of the aggregate balance of our pre-petition Senior Notes of $6.5 billion, amounts drawn under the Revolving Credit Facility as of the Petition Date of $581.0 million and the corresponding unpaid accrued interest as of the Petition Date of $203.5 million.

The contractual interest expense on the outstanding Senior Notes and the Revolving Credit Facility was in excess of recorded interest expense by $132.9 million for the four months ended April 30, 2021 (Predecessor). This excess contractual interest was not included as interest expense on our Consolidated Statements of Operations as we had discontinued accruing interest on the Predecessor's Senior Notes and Revolving Credit Facility subsequent to the Petition Date. The Predecessor discontinued making interest payments on the Senior Notes beginning in June 2020.

Reorganization Items

Expenditures, gains and losses that are realized or incurred by the Debtors as of or subsequent to the Petition Date and as a direct result of the Chapter 11 Cases are reported as Reorganization items, net in our Consolidated Statements of Operations for the year ended December 31, 2022, eight months ended December 31, 2021 (Successor) and four months ended April 30, 2021 (Predecessor). These costs include legal and other professional advisory service fees pertaining to the Chapter 11 Cases and the effects of the emergence from bankruptcy, including the application of fresh start accounting.

The components of reorganization items, net were as follows (in millions):

3. FRESH START ACCOUNTING

Applicability of Fresh Start Accounting

Upon emergence from bankruptcy, we qualified for and applied fresh start accounting, which resulted in the Company becoming a new entity for financial reporting purposes because (1) the holders of the then existing Class A ordinary shares of the Predecessor received less than 50 percent of the Common Shares of the Successor outstanding upon emergence and (2) the reorganization value of the Company’s assets immediately prior to confirmation of the plan of reorganization was less than the total of all post-petition liabilities and allowed claims.

The reorganization value derived from the range of enterprise values associated with the plan of reorganization was allocated to the Company’s identifiable tangible and intangible assets and liabilities based on their fair values (except for deferred income taxes). The amount of deferred income taxes recorded was determined in accordance with the applicable income tax accounting standard. The April 30, 2021 fair values of the Company’s assets and liabilities differ materially from their recorded values as reflected on the historical balance sheets.

Reorganization Value

The reorganization value represents the fair value of the Successor's total assets and was derived from the enterprise value associated with the plan of reorganization, which represents the estimated fair value of $1.8 billion. an entity's long-term debt and equity less unrestricted cash upon emergence from chapter 11. As set forth in the disclosure statement and approved by the Bankruptcy Court, third-party valuation advisors estimated the enterprise value to be between $1,860.0 million and $3,145.0 million. The enterprise value range of the reorganized Debtors was determined primarily by using a discounted cash flow analysis. The value agreed in the plan of reorganization is indicative of an enterprise value at the low end of this range, or $1,860.0 million.

The following table reconciles the enterprise value to the estimated fair value of Successor Common Shares as of the Effective Date (in millions, except per share value):
April 30, 2021
Enterprise Value$1,860.0 
Plus: Cash and cash equivalents607.6

Less: Noncontrolling interest1.1 
Less: Pension and other post-retirement benefits liabilities(189.0)
Less: Adjustments not contemplated in Enterprise Value(639.0)
Fair value of Successor Common Shares$1,079.5 
Shares issued upon emergence75.0 
Per share value$14.39 

The following table reconciles the enterprise value to the reorganization value as of the Effective Date (in millions):
April 30, 2021
Enterprise Value$1,860.0 
Plus: Cash and cash equivalents607.6 
Plus: Non-interest bearing current liabilities346.0 
Less: Adjustments not contemplated in Enterprise Value(218.0)
Reorganization value of Successor assets$2,595.6 

90


Adjustments not contemplated in Enterprise Value represent certain obligations of the Successor that were either not contemplated or contemplated in a different amount in the forecasted cash flows of the enterprise valuation performed by third-party valuation advisors that, had they incorporated those anticipated cash flows into their analysis, the resulting valuation would have been different. For the reconciliation of Reorganization value of Successor assets, this item includes certain tax balances, contract liabilities, as well as an adjustment for the fair value of pension obligations. The reconciliation to Successor Common Share value includes these same reconciling items as well as other current and non-current liabilities of the Successor at the emergence.

The enterprise value and corresponding implied equity value are dependent upon achieving the future financial results set forth in the valuation utilizing assumptions regarding future day rates, utilization, operating costs and capital requirements as of the emergence date. All estimates, assumptions, valuations and financial projections, including the fair value adjustments, the enterprise value and equity value projections, are inherently subject to significant uncertainties and the resolution of contingencies beyond our control. Accordingly, there is no assurance that the estimates, assumptions, valuations or financial projections will be realized, and actual results could vary materially.

Valuation Process

The fair values of the Company's principal assets and liabilities including property, plant and equipment as well as our 50% equity interest in ARO and our Notes Receivable from ARO, options to purchase VALARIS DS-13 and VALARIS DS-14 (the "Newbuild Drillships"), the First Lien Notes, pensions and Warrants were estimated with the assistance of third-party valuation advisors.

Property, Plant and Equipment

The valuation of the Company’s drilling rigs was estimated by using an income approach or estimated sales price. These valuations were based on unobservable inputs that require significant judgments for which there is limited information, including, in the case of an income approach, assumptions regarding future day rates, utilization, operating costs, reactivation costs and capital requirements. In developing these assumptions, forecasted day rates and utilization took into account current market conditions and our anticipated business outlook. The cash flows were discounted at our weighted average cost of capital, which was derived from a blend of our after-tax cost of debt and our cost of equity and computed using public share price information for similar offshore drilling market participants, certain U.S. Treasury rates and certain risk premiums specific to the Company.

Our remaining property and equipment, including owned real estate and other equipment, was valued using a cost approach, in which the estimated replacement cost of the assets was adjusted for physical depreciation and obsolescence, where applicable, to arrive at estimated fair value.

The estimated fair value of our property and equipment includes an adjustment to reconcile to our reorganization value.

Notes Receivable from ARO

The fair value of the Notes Receivable from ARO was estimated using an income approach to value the forecasted cash flows attributed to the Notes Receivable from ARO using a discount rate based on a comparable yield with a country-specific risk premium.

91


Investment in ARO

We estimated the fair value of the rigs and equipmentequity investment in ARO primarily by applying an income approach, using projected discounted cash flows orof the underlying assets, a market approach. Werisk-adjusted discount rate and an estimated remaining useful lives for Atwood's drilling rigs, which ranged from 16effective income tax rate.

Options to 35 years based on original estimated useful lives of 30 to 35 years.Purchase Newbuild Drillships

Deferred Taxes


The Merger was executed through the acquisition of Atwood's outstanding common stock and, therefore, the historical tax basesfair value of the acquired assets and assumed liabilities, net operating losses and other tax attributes of Atwood were assumed as of the Merger Date.  However, adjustments were recordedoptions to recognize deferred tax assets and liabilities for the tax effects of differences between acquisition date fair values and tax bases of assets acquired and liabilities assumed. Additionally, the interaction of our and Atwood's tax attributes that impacted the deferred taxes of the combined entity were also recognized as part of acquisition accounting. As of the Merger Date,purchase Newbuild Drillships was estimated using an increase of $2.5 million to Atwood’s net deferred tax liability was recognized.     

Deferred tax assets and liabilities recognized in connection with the Merger were measured at rates enacted as of the Merger Date.  Tax rate changes, or any deferred tax adjustments for new tax legislation, following the Merger Date, including the recently enacted U.S. tax reform , will be reflected in our operating results in the period in which the change in tax laws or rate is enacted.

Intangible Assets and Liabilities

We recorded intangible assets totaling $33.3 million representingoption pricing model utilizing the estimated fair value of Atwood'sa newbuild rig, estimated purchase price upon exercise of the options, the holding period, equity volatility and the risk-free rate.

First Lien Notes

The fair value of the First Lien Notes was determined to approximate the par value based on third-party valuation advisors’ analysis of the Company’s collateral coverage, financial metrics, and interest rate for the First Lien Notes relative to market rates of recent placements of a similar term for industry participants with similar credit risk.

Pensions

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. Upon emergence, our pension and other postretirement plans were remeasured as of the Effective Date. Key assumptions at the Effective Date included (1) a weighted average discount rate of 2.81% to determine pension benefit obligations and (2) an expected long-term rate of return on pension plan assets of 6.03% to determine net periodic pension cost.

Warrants

The fair value of the Warrants was determined using an option pricing model considering the contractual terms of the Warrant issuance. The key market data assumptions for the option pricing model are the estimated volatility and the risk-free rate. The volatility assumption was estimated using market data for offshore drilling market participants with consideration for differences in leverage. The risk-free rate assumption was based on U.S. Treasury Constant Maturity rates with a comparable term.

Condensed Consolidated Balance Sheet

The adjustments included in the following Condensed Consolidated Balance Sheet reflect the effects of the transactions contemplated by the plan of reorganization and executed by the Company on the Effective Date (reflected in the column “Reorganization Adjustments”), and fair value and other required accounting adjustments resulting from the adoption of fresh start accounting (reflected in the column “Fresh Start Accounting Adjustments”). The explanatory notes provide additional information with regard to the adjustments recorded.

Our supplemental executive retirement plans are non-qualified plans that provided eligible employees an opportunity to defer a portion of their compensation for use after retirement. The plans were frozen to the entry of new participants in 2019 and to future compensation deferrals as of January 1, 2020. Upon emergence, assets previously held in a rabbi trust maintained for the plan were liquidated and the plan was amended.

In accordance with the amended agreement with the Shipyard, our leases were terminated and we have eliminated the historical right-of-use asset associated with the berthing locations of Newbuild Drillships.

Additionally, upon effectiveness of the plan of reorganization, the amended agreement with the Shipyard provides the Company with the option to purchase the Newbuild Drillships. The reorganization adjustments include an asset that reflects the fair value of the option to purchase the Newbuild Drillships and embedded feature related to the ability, under the amended agreements with the Shipyard, for the equity issued pursuant to this arrangement to be put to the Company for $8.0 million of consideration for each rig, should we choose to take delivery.

$(55.2)

The reorganization adjustments to other liabilities primarily relate to the elimination of construction contract intangible liabilities associated with the Newbuild Drillships. These construction contract intangible liabilities were recorded in purchase accounting for the original contracting entity. As the amended contract was structured as an option whereby we had the right, not the obligation to take delivery of the rigs, there was no longer an intangible liability associated with the contracts.

Fresh Start Adjustments

(o)    Other current assets

Reflects the fresh start adjustments to record the estimated fair value of other current assets as follows (in millions):

Elimination of materials and supplies$(260.8)
Elimination of historical deferred contract drilling expenses(20.3)
$(281.1)

Primarily reflects the fresh start adjustment to eliminate the historical balance for materials and supplies as the result of a change in accounting policies upon emergence. Historically, we recognized materials and supplies on the balance sheet when purchased and subsequently expensed items when consumed. Upon emergence from bankruptcy, we elected to change our accounting policies related to materials and supplies whereby materials and supplies will be expensed as a period cost when received. Additionally, a customer arrangement provides that we take title to their materials and supplies for the duration of the contract and return or pay cash for them at the termination of the contract. Together with our policy change on materials and supplies, we elected to record these assets and the obligation to our customer on a net basis as opposed to a gross basis.

The fresh start adjustment for the elimination of historical deferred contract drilling expenses primarily relates to deferred mobilization costs, deferred contract preparation costs and deferred certification costs. Costs incurred for mobilization and contract preparation prior to the commencement of drilling services are deferred and subsequently amortized over the term of the related drilling contract. Additionally, we must obtain certifications from various regulatory bodies in order to operate our drilling rigs and must maintain such certifications through periodic inspections and surveys. The costs incurred in connection with maintaining such certifications, including inspections, tests, surveys and drydock, as well as remedial structural work and other compliance costs, are deferred and amortized on a straight-line basis over the corresponding certification periods. These deferred costs had no future economic benefit and were eliminated from the fresh start financial statements.

(p)    Property and equipment, net

Reflects the fresh start adjustments to historical amounts to record the estimated fair value of property and equipment.

Furthermore, upon emergence from bankruptcy, we elected to change our accounting policies and have identified the significant components of our drilling rigs and ascribed useful lives based on the expected time until the next required overhaul or the end of the expected economic lives of the components. Prior to emergence, we recorded our drilling rigs as a single asset with a useful life ascribed by the expected useful life of that asset.

(q)    Notes Receivable from ARO

Reflects the fresh start adjustment to record the estimated fair value of the Notes Receivable from ARO.

The fresh start adjustment to right-of-use assets reflects the remeasuring of our operating leases as of the emergence date. Certain operating leases had unfavorable terms as of the emergence date, and as a result the right-of-use asset for these intangible assets is estimatedsuch leases did not equal the lease liability upon emergence.

The fresh start adjustment to be $11.4 millioneliminate historical deferred contract drilling expenses reflects the noncurrent portion of historical deferred contract drilling expenses described in (o) above as well as the elimination of customer contract intangibles previously recorded in purchase accounting for a 2019 transaction.

The fresh start adjustment to eliminate the firm obligationscustomer payable balance is related to the change in accounting policy to present the balance on a net basis.

The fresh start adjustment to eliminate historical deferred revenues is primarily related to amounts previously received for the reimbursement for capital upgrades, upfront contract deferral fees and mobilization. Such amounts are deferred and subsequently amortized over the term of the related drilling contract. The deferred revenue did not represent any future performance obligations and was therefore eliminated as a fresh start accounting adjustment.

The fresh start adjustment to record the estimated fair value of contracts with customers reflects the intangible liabilities recognized for firm customer contracts in place at the Effective Date that have unfavorable contract terms as compared to current market day rates for comparable drilling rigs. The various factors considered in the adjustment and computation of the intangible liabilities are described in (s) above.

4.  REVENUE FROM CONTRACTS WITH CUSTOMERS
Under our drilling contracts with customers, we provide a drilling rig and drilling services, including rig crews, on a day rate basis. We receive a daily rate that may vary between the full rate and zero rate throughout the duration of the contractual term, depending on the operations of the rig. We also may receive lump-sum fees or similar compensation generally for the mobilization, demobilization and capital upgrades of our rigs. 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.

100


Our drilling contracts contain a lease component and we have elected to apply the practical expedient provided under Accounting Standards Codification ("ASC") 842 to not separate the lease and non-lease components and apply the revenue recognition guidance in ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)." Our drilling service provided under each drilling contract is a single performance obligation satisfied over time and comprised of a series of distinct time increments, or service periods. Total revenue is determined for each individual drilling contract by estimating both fixed and variable consideration expected to be earned over the contract term. Fixed consideration generally relates to activities such as mobilization, demobilization and capital upgrades of our rigs that are not distinct performance obligations within the context of our contracts and is recognized on a straight-line basis over the contract term. Variable consideration generally relates to distinct service periods during the contract term and is recognized in the period when the services are performed.

The amount estimated current marketfor variable consideration is only recognized as revenue to the extent that it is probable that a significant reversal will not occur during the contract term. We have applied the optional exemption afforded in ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)," and have not disclosed the variable consideration related to our estimated future day rate revenues. The remaining duration of our drilling contracts based on those in place as of December 31, 2023 was between approximately 1 month and 5 years.

Day Rate Drilling Revenue

Our drilling contracts provide for payment on a day rate basis and include a rate schedule with higher rates for periods when the construction of a comparable drilling rig.rig is operating and lower rates or zero rates for periods when drilling operations are interrupted or restricted. The unfavorable construction liability was calculatedday rate invoiced to the customer is determined based on the present valuevarying rates applicable to specific activities performed on an hourly or other time increment basis. Day rate consideration is allocated to the distinct hourly or other time increment to which it relates within the contract term and is generally recognized consistent with the contractual rate invoiced for the services provided during the respective period. Invoices are typically issued to our customers on a monthly basis and payment terms on customer invoices are typically 30 days.

Certain of our contracts contain performance incentives whereby we may earn a bonus based on pre-established performance criteria. Such incentives are generally based on our performance over individual monthly time periods or individual wells. Consideration related to performance bonus is generally recognized in the specific time period to which the performance criteria was attributed.

We may receive termination fees if certain drilling contracts are terminated by the customer prior to the end of the differencecontractual term. Such compensation is recognized as revenue when our performance obligation is satisfied, the termination fee can be reasonably measured and collection is probable.

Contract Termination - VALARIS DS-11

In 2021, a contract was awarded to VALARIS DS-11 for a project in cash outflowsthe U.S. Gulf of Mexico that was expected to commence in mid-2024. In June 2022, the customer terminated the contract. As a result of the contract termination, we received an early termination fee of $51.0 million which is included in revenues on our Consolidated Statements of Operations for the remaining contractual payments as comparedyear ended December 31, 2022 (Successor).

Mobilization / Demobilization Revenue

In connection with certain contracts, we receive lump-sum fees or similar compensation for the mobilization of equipment and personnel prior to a hypotheticalthe commencement of drilling services or the demobilization of equipment and personnel upon contract completion. Fees received for the mobilization or demobilization of equipment and personnel are included in Operating revenues. The costs incurred in connection with the same remaining contractual payments at estimated then-current market rates usingmobilization and demobilization of equipment and personnel are included in Contract drilling expense.

Mobilization fees received prior to commencement of drilling operations are recorded as a risk-adjusted discount ratecontract liability and an estimated effective income tax rate. The liabilities will be amortized on a straight-line basis over the contract term. Demobilization fees expected to be received upon contract completion are estimated lifeat contract inception and recognized on a straight-line basis over the contract term. In some cases, demobilization fees may be contingent upon the occurrence or non-occurrence of ENSCO DS-13a future event. In such cases, this may result in cumulative-effect adjustments to demobilization revenues upon changes in our estimates of future events during the contract term.

Capital Upgrade / Contract Preparation Revenue

In connection with certain contracts, we receive lump-sum fees or similar compensation generally for requested capital upgrades to our drilling rigs or for other contract preparation work. Fees received for requested capital upgrades and ENSCO DS-14other contract preparation work are recorded as a reductioncontract liability and amortized on a straight-line basis over the contract term to Operating revenues.

Revenues Related to Reimbursable Expenses

We generally receive reimbursements from our customers for purchases of depreciation expense beginningsupplies, equipment, personnel services and other services provided at their request. Such reimbursable revenue is variable and subject to uncertainty, as the amounts received and timing thereof are highly dependent on factors outside of our influence. Accordingly, reimbursable revenue is recognized during the dateperiod in which the rigcorresponding goods and services are consumed once the uncertainty is placed into service.resolved, which typically occurs when the related costs are incurred on behalf of a customer. We are generally considered a principal in such transactions and record the associated revenue at the gross amount billed to the customer within Operating revenues.


Pro Forma ImpactContract Assets and Liabilities

Contract assets represent amounts recognized as revenue but for which the right to invoice the customer is dependent upon our future performance. Once the previously recognized revenue is invoiced, the corresponding contract asset, or a portion thereof, is transferred to accounts receivable.

Contract liabilities generally represent fees received for mobilization, capital upgrades or in the case of our 50/50 unconsolidated joint venture with Saudi Aramco, represent the Mergerdifference between the amounts billed under the bareboat charter arrangements and lease revenues earned. See “Note 5 – Equity Method Investment in ARO" for additional details regarding our balances with ARO.

5. EQUITY METHOD INVESTMENT IN ARO

Background

ARO is a 50/50 unconsolidated joint venture between the Company and Saudi Aramco that owns and operates offshore drilling rigs in Saudi Arabia. As of December 31, 2023, ARO owned eight jackup rigs, had ordered one newbuild jackup rigs and leased eight rigs from us through bareboat charter arrangements (the "Lease Agreements") whereby substantially all operating costs are incurred by ARO. At December 31, 2023, the leased rigs were operating under three-year drilling contracts, or related extensions, with Saudi Aramco. The eight rigs owned by ARO are currently operating under contracts with Saudi Aramco, each with a minimum aggregate contract term of 15 years, provided that the rigs meet the technical and operational requirements of Saudi Aramco.

The shareholder agreement governing the joint venture (the "Shareholder Agreement") specifies that ARO shall purchase 20 newbuild jackup rigs over an approximate 10-year period. The first two newbuild jackups were ordered in January 2020, the first of which, Kingdom 1, was delivered and commenced operations in the fourth quarter of 2023, and the second is expected to be delivered in the first half of 2024. ARO is expected to commit to orders for two additional newbuild jackups in the near term. In connection with these plans, we have a potential obligation to fund ARO for newbuild jackup rigs. See “Note 13 Commitments and Contingencies" for additional information.

The joint venture partners agreed in the Shareholder Agreement that Saudi Aramco, as a customer, will provide drilling contracts to ARO in connection with the acquisition of the newbuild rigs. The initial contracts provided by Saudi Aramco for each of the newbuild rigs will be for an eight-year term. The day rate for the initial contracts for each newbuild rig is 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.

Summarized Financial Information

The operating revenues of ARO presented below reflect revenues earned under drilling contracts with Saudi Aramco for the ARO-owned jackup rigs as well as the rigs leased from us. Contract drilling expense is inclusive of the bareboat charter fees for the rigs leased from us. See additional discussion below regarding these related-party transactions.

Equity in Earnings of ARO

We account for our interest in ARO using the equity method of accounting and only recognize our portion of ARO's net income, adjusted for basis differences as discussed below, which is included in Equity in earnings of ARO in our Consolidated Statements of Operations. ARO is a variable interest entity; however, we are not the primary beneficiary and therefore do not consolidate ARO. Judgments regarding our level of influence over ARO included considering key factors such as each partner's ownership interest, representation on the board of managers of ARO and ability to direct activities that most significantly impact ARO's economic performance, including the ability to influence policy-making decisions. Our investment in ARO would be assessed for impairment if there are changes in facts and related methodologies usedcircumstances that indicate a loss in value may have occurred. If a loss were deemed to manage foreign currency exchange rate risk. Thehave occurred and this loss was determined to be other than temporary, the carrying value of our investment would be written down to fair value measurementsand an impairment recorded.

We have an equity method investment in ARO that was recorded at its estimated fair value at both the Effective Date and also on the date of our derivatives2019 transaction where we acquired the subsidiary that held the joint venture interest. We computed the difference between the fair value of ARO's net assets and the carrying value of those net assets in ARO's U.S. GAAP financial statements ("basis differences") on each of these dates. These basis differences primarily related to ARO's long-lived assets and the recognition of intangible assets associated with certain of ARO's drilling contracts that were based ondetermined to have favorable terms relative to market prices thatterms as of the measurement dates.

Upon completion of the lease term, such amounts become a payable to or a receivable from ARO.

During 2017 and 2018, the Company contributed assets to ARO in exchange for the 10-year Notes Receivable from ARO, and as amended in December 2023, bear interest based on a one-year term SOFR, set as of the end of the year prior to the year applicable, plus 2.10%. The Notes Receivable from ARO were adjusted to the estimated fair value as of the Effective Date and the resulting discount to the principal amount is being amortized using the effective interest method to interest income over the remaining terms of the notes.

Impairment of Long-Lived Assets


On a quarterly basis, we evaluate the carrying value of our property and equipment to identify events or changes in circumstances ("triggering events") that indicate the carrying value may not be recoverable.

During 2017, we recognized a pre-tax, non-cash loss on impairment of $182.9 million related to older, less capable, non-core assets in our fleet. During the fourth quarter, we determined that the remaining useful life of certain non-core rigs would not extend substantially beyond their current contracts, resulting in triggering events and the performance of recoverability tests. Our estimates of undiscounted cash flows over the revised estimated remaining useful lives were not sufficient to recover each asset’s carrying value. Accordingly, we concluded that two semisubmersibles and one jackup were impaired as of December 31, 2017.

During 2015, we recognized a pre-tax, non-cash loss on impairment of $2.6 billion, of which $2.5 billion was included in income (loss) from continuing operations and $148.6 million was included in income (loss) from discontinued operations, net, in our consolidated statement of operations. The impairments recognized during 2015 resulted from adverse changes in our business climate that led to the conclusion that triggering events had occurred across our fleet.
For rigs whose carrying values wereare determined not to be recoverable, during 2017 and 2015, we recordedrecord an impairment for the difference between their fair values and carrying values.

Successor

In June 2022, the drilling contract previously awarded to VALARIS DS-11 was terminated. As of the date of termination, we had incurred costs to upgrade the rig pursuant to the requirements of the contract. Costs incurred related to these capital upgrades were included in work-in-progress and upon termination were determined to be impaired. We recorded a pre-tax, non-cash loss on impairment in the second quarter of 2022 of $34.5 million. See "Note 4 - Revenue from Contracts with Customers" for additional information regarding the termination.

Predecessor

During the first quarter of 2021, as a result of challenging market conditions for certain of our floaters, we revised our near-term operating assumptions which resulted in a triggering event for purposes of evaluating impairment. We determined that the estimated undiscounted cash flows were not sufficient to recover the carrying values for certain rigs and concluded they were impaired as of March 31, 2021.

Based on the asset impairment analysis performed as of March 31, 2021, we recorded a pre-tax, non-cash loss on impairment in the first quarter of 2021 for certain floaters totaling $756.5 million, inclusive of $5.6 million of gains reclassified from accumulated other comprehensive income into loss on impairment associated with related cash flow hedges. We measured the fair valuesvalue of these rigsassets to be $26.0 million at the time of impairment by applying either an income approach, using projected discounted cash flows, or a market approach.estimated sales price. These valuations were based on unobservable inputs that require significant judgments for which there is limited information, including, in the case of an income approach, assumptions regarding future day rates, utilization, operating costs and capital requirements.

In instances where we applied an income approach, forecasted day rates and utilization took into account then current market conditions and our anticipated business outlook. In instances where

Further, the Credit Agreement contains financial covenants that require us to maintain (i) a total debtminimum book value of equity to total capitalizationassets ratio, that is less than or equal to 60%(ii) a minimum interest coverage ratio 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(iii) a permitted lien basket that permits us to raise secured debt up to the lesser of $750 million 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 continue paying 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 aggregateminimum amount of available cash (as defined in the Credit Facility) would exceed $150 million; and entering into certain transactions with affiliates.liquidity.


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, 2017,2023, 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 2017.Agreement. We had no amounts outstanding under the Credit FacilityAgreement as of December 31, 2017and 2016.

Our access to credit and capital markets depends on the credit ratings assigned to our debt. As a result of recent rating actions by these agencies, we no longer maintain an investment-grade status. Our current credit ratings, and any additional actual or anticipated downgrades in our credit ratings, could limit our available options when accessing credit and capital markets, or when restructuring or refinancing our debt. In addition, future financings or refinancings may result in higher borrowing costs and require more restrictive terms and covenants, which may further restrict our operations.

6.  DERIVATIVE INSTRUMENTS
We use derivatives to reduce our exposure to various market risks, primarily foreign currency exchange rate risk. 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 mitigate our credit risk relating to the counterparties of our derivatives by transacting with multiple, high-quality financial institutions, thereby limiting 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. See "Note 14 - Supplemental Financial Information" for additional information on the mitigation of credit risk relating to counterparties of our derivatives. We do not enter into derivatives for trading or other speculative purposes.
All derivatives were recorded on our consolidated balance sheets at fair value. Derivatives subject to legally enforceable master netting agreements were not offset on our consolidated balance sheets. Accounting for the gains and losses resulting from changes in the fair value of derivatives depends on the use of the derivative and whether it qualifies for hedge accounting. See "Note 1 - Description of the Business and Summary of Significant Accounting Policies" for additional information on our accounting policy for derivatives and "Note 3 - Fair Value Measurements" for additional information on the fair value measurement of our derivatives.


As of December 31, 2017 and 2016, our consolidated balance sheets included net foreign currency derivative assets of $6.8 million and liabilities of $8.8 million, respectively.  All of our derivatives mature within the next 18 months.  

Derivatives recorded at fair value on our consolidated balance sheets as of December 31, 2017 and 2016 consisted of the following (in millions):

We utilize cash flow hedges to hedge forecasted foreign currency denominated transactions, primarily to reduce our exposure to foreign currency exchange rate risk associated with contract drilling expenses and capital expenditures denominated in various currencies.  As of December 31, 2017, we had cash flow hedges outstanding to exchange an aggregate $188.4 million for various foreign currencies, including $82.2 million for British pounds, $47.8 million for Australian dollars, $27.0 million for euros, $19.9 million for Brazilian reals, $10.4 million for Singapore dollars and $1.1 million for other currencies.

Gains and losses, net of tax, on derivatives designated as cash flow hedges included in our consolidated statements of operations and comprehensive income for each of the years in the three-year period ended December 31, 2017 were as follows (in millions):

Changes in the fair value of cash flow hedges are recorded in AOCI.  Amounts recorded in AOCI associated with cash flow hedges are subsequently reclassified into contract drilling, depreciation or interest expense as earnings are affected by the underlying hedged forecasted transaction.



(2)
Gains and losses recognized in income for ineffectiveness and amounts excluded from effectiveness testing were included in other, net, in our consolidated statements of operations.

(3)
Losses on interest rate lock derivatives reclassified from AOCI into income (effective portion) were included in interest expense, net, in our consolidated statements of operations.

(4)
During the year ended December 31, 2017, $1.1 million of losses were reclassified from AOCI into contract drilling expense and $900,000 of gains were reclassified from AOCI into depreciation expense in our consolidated statement of operations. During the year ended December 31, 2016, $13.1 million of losses were reclassified from AOCI into contract drilling expense and $900,000 of gains were reclassified from AOCI into depreciation expense in our consolidated statement of operations. During the year ended December 31, 2015, $22.5 million of losses were reclassified from AOCI into contract drilling and $900,000 of gains were reclassified from AOCI into depreciation expense in our consolidated statement of operations.

We have net assets and liabilities denominated in numerous foreign currencies and use various methods to manage our exposure to foreign currency exchange rate risk. 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. We occasionally enter into derivatives that hedge the fair value of recognized foreign currency denominated assets or liabilities but 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 fair value of the underlying hedged items. As of December 31, 2017, we held derivatives not designated as hedging instruments to exchange an aggregate $131.1 million for various foreign currencies, including $93.3 million for euros, $9.6 million for Brazilian reals, $7.4 million for Indonesian rupiah, $5.6 million for British pounds, $5.4 million for Australian dollars and $9.8 million for other currencies.

Net gains of $10.0 million, and net losses of $7.0 million and $17.3 million associated with our derivatives not designated as hedging instruments were included in other, net, in our consolidated statements of operations for the years ended December 31, 2017, 2016 and 2015,2021 (Successor), respectively.

As of December 31, 2017, the estimated amount of net gains associated with derivatives, net of tax, that will be reclassified to earnings during the next 12 months was as follows (in millions):


113
Net unrealized gains to be reclassified to contract drilling expense $3.1
Net realized gains to be reclassified to depreciation expense .9

For senior officers, delivery of the shares underlying certain vested restricted stock unit awards is deferred until the third anniversary of the date of grant.

Non-employee directors received a one-time grant of time-based restricted awards upon our emergence from the Chapter 11 Cases which vest ratably over a three-year period from the date of grant. Additionally, non-employee directors receive an annual grant of time-based restricted awards which vest in full on the earlier of the first anniversary of the grant date or the next annual meeting of shareholders following the grant. Non-employee directors are permitted to elect to receive deferred share awards which can be settled and delivered on the six-month anniversary following the termination of the director's service or a specific pre-determined date.

Our time-based share awards do not have voting or participating rights as the dividend equivalent provided for in the award agreement is forfeitable (except in certain limited circumstances) and further our debt agreements limit our ability to pay dividends and none have been declared. Compensation expense for share awards is measured at fair value on the date of grant and recognized on a straight-line basis over the requisite service period (usually the vesting period). Compensation expense for cash-settled awards is remeasured each quarter with a cumulative adjustment to compensation cost during the period based on changes in our share price. Our compensation cost is reduced for forfeited awards in the period in which the forfeitures occur.

Performance Awards


Under the 2012 LTIP,Company's MIP, performance awards may be issued to our senior executive officers. Performance awards generally vest at the end of a three-year measurement period based on attainment of performance goals.

The performance awards granted in 2021 and 2022 are based on three performance goals and subject to achievement of specifiedthose performance goals based on relative total shareholder return ("TSR"(a) designated share price hurdles whereby our closing stock price must equal or exceed certain market price targets for ninety consecutive trading days (the "Share Price Objective") and; (b) relative return on capital employed ("ROCE"). The performance as compared to a specified peer group, all as defined in the award agreements (the "ROCE Objective"), and (c) specified strategic goals are determinedas established by a committee or subcommitteethe Compensation Committee of the Boardboard of Directors.

These awards are payable in either Ensco shares or cash uponequity following a three-year performance period and subject to attainment of relative TSR and ROCEsuch objectives ranging from 0% to 150% of target performance goals. Performance awards granted during 2017 are payable in cash whileunder such objectives.

The performance awards granted in 20152023 include awards which are subject to the achievement of goals based on our absolute total shareholder return and 2016our total shareholder return relative to a specified peer group (the "TSR Objectives" and together with the Share Price Objective, the "Market-Based Objectives"). These awards are payable in Ensco shares.

Ourequity at a range from 0% to 200% of target performance following a three-year performance period. Also, in 2023, incremental awards granted during 2017 are classified as liability awards with compensation expense measured based on the estimated probability of attainment of the specified performance goals and recognized on a straight-line basis over the requisite service period. Strategic Goal Objective were granted.

The estimated probable outcome of attainment of the specified performance goals is based primarily on historical experience, and anyrelative performance over the requisite performance period. Any subsequent changes in this estimate as it relates to the Performance-Based Objectives are recognized as a cumulative adjustment to compensation cost in the period in which the change in estimate occurs.

The aggregatefair value of the performance awards granted during the years ended December 31, 2023 and 2022, and eight months ended December 31, 2021 (Successor) are measured on the date of grant. The grant-date fair value per unit for the portion of the performance awards related to Performance-Based Objectives was equal to the closing price of the Company's stock on the grant date. The portion of these awards that were based on the Company's achievement of Market-based Objectives were valued at the date of grant using a Monte Carlo simulation with the following weighted average assumptions for the grants made over the years ended December 31, 2023 and 2022, and eight months ended December 31, 2021 (Successor):

The expected price volatility assumption is estimated using market data for certain peer companies during periods in which our own trading history is limited. As our trading history increases, it will bear greater weight in determining our expected price volatility assumption.

The weighted average grant-date fair value of performance awards granted during 2017, 2016the years ended December 31, 2023 and 2015 totaled $6.7 million, $6.1 million2022, and $8.3 million,eight months ended December 31, 2021 (Successor) was $62.09, $38.08 and $15.93, respectively.

Predecessor Awards

Time-Based Share Awards and Cash-Settled Awards

The Predecessor granted share awards and share units (collectively "share awards") and share units to be settled in cash ("cash-settled awards"), which generally vested at a rate of 33% per year. Additionally, non-employee directors were permitted to elect to receive deferred share awards. Deferred share awards vested at the earlier of the first anniversary of the grant date or the next annual meeting of shareholders following the grant but were not to be settled until the director terminated service from the board of directors. Deferred share awards were to be settled in cash, shares or a combination thereof at the discretion of the compensation committee.

The Predecessor's non-vested share awards had voting and dividend rights effective on the date of grant, and the non-vested share units had dividend rights effective on the date of grant. Compensation expense for share awards was measured at fair value on the date of grant and recognized on a straight-line basis over the requisite service period (usually the vesting period). Compensation expense for cash-settled awards was remeasured each quarter with a cumulative adjustment to compensation cost during the period based on changes in the Legacy Valaris share price. Compensation cost was also reduced for forfeited awards in the period in which the forfeitures occurred.

During the four months ended April 30, 2021 (Predecessor) we recognized $4.8 million of compensation expense for these awards, of which $2.4 million was included in Contract drilling expense and $2.4 million was included in General and administrative expense in our Consolidated Statements of Operations. As discussed above, in accordance with the plan of reorganization, the unvested awards of employees, senior executive officers and non-employee directors remaining on the Effective Date were cancelled for no consideration.

Share Appreciation Rights

Share Appreciation Rights ("SARs") granted to employees under our Predecessor incentive plans were accounted for as equity awards. As of April 30, 2021, there were 319,641 SARs outstanding, all of which were fully vested. In accordance with the plan of reorganization, these remaining outstanding SARs were cancelled.

Share Option Awards

As of April 30, 2021, there were fully vested options outstanding to purchase 313,377 shares under our Predecessor incentive plans. In accordance with the plan of reorganization, these outstanding options were cancelled.

11.  PENSION AND OTHER POST-RETIREMENT BENEFITS

We have defined-benefit pension plans and post-retirement health and life insurance plans that provide benefits upon retirement for certain full-time employees. The defined-benefit pension plans include: (1) a pension plan which was amended in 2018 to freeze any future benefit accrual whereby eligible employees no longer receive pay credits in the plan and newly hired employees are not eligible to participate; and (2) supplemental executive retirement plans, which are also frozen, that provided eligible employees an opportunity to defer a portion of their compensation for use after retirement. Additionally, we have frozen retiree life and medical supplemental plans which provide post-retirement health and life insurance benefits.

The American Rescue Plan Act of 2021, which was passed in March 2021, provided funding relief for U.S. qualified pension plans which lowered our pension contribution requirements for the years ended December 31, 2023 and 2022. We currently expect to contribute approximately $23.7 million to our pension plans and to directly pay other post-retirement benefits of approximately $1.2 million in 2024. These amounts represent the minimum contributions we are required to make under relevant statutes. We do not expect to make contributions in excess of the minimum required amounts.

The pension plans' investment objectives for fund assets are to: achieve a rate of return such that contributions are minimized and future assets are available to fund liabilities, maintain liquidity sufficient to pay benefits when due, diversify among asset classes so that assets earn a reasonable return with an acceptable level of risk and gradually de-risk the plan by increasing the allocation of investments which track the overall liabilities of the plan as the ratio of assets to liabilities improves and economic conditions warrant. The plans employ several active managers with proven long-term records in their specific investment discipline.

(1)Our investment policy only sets allocation target ranges for general asset classes and not specific investment types.

All of our investments, other than cash and cash equivalents, are measured at fair value using the net asset value per share (or its equivalent) practical expedient and therefore are not categorized in the fair value hierarchy. Cash and cash equivalents are considered Level 1 as they were valued at cost, which approximates fair value.

Assets in the U.S. equities category include investments in common and preferred stocks (and equivalents such as American Depository Receipts and convertible bonds) and may be held through separate accounts, commingled funds or an institutional mutual fund. Assets in the global low volatility equities include investments in a broad range of developed market global equity securities and may be held through a commingled or institutional mutual fund. Assets in the international equities category include investments in a broad range of international equity securities, including both developed and emerging markets, and may be held through a commingled or institutional mutual fund. The real estate category includes investments in pooled and commingled funds whose objectives are diversified equity investments in income-producing properties. Each real estate fund is intended to provide broad exposure to the real estate market by property type, geographic location and size and may invest internationally. Securities in the fixed income categories include U.S. government, corporate, mortgage- and asset-backed securities and Yankee bonds and should be rated investment grade or above. Investments in this category should have an average investment rating of “A” or better.

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 plan's 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 decreased to 6.88% at December 31, 2023 from 7.10% at December 31, 2022.

Savings Plans


We have profit sharingsavings plans, (the "Ensco"Savings Plan", the "Multinational Savings Plan,"Plan", the "Ensco Multinational Savings Plan" and the "Ensco Limited"Limited Retirement Plan"), which cover eligible employees as defined within each plan. The Ensco Savings Plan includes a 401(k) savings plan feature, which allows eligible employees to make tax-deferred contributions to the plan.  The Ensco Limited Retirement Plan also allows eligible employees to make tax-deferred contributions to the plan.plans. Contributions made to the Ensco Multinational Savings Plan may or may not qualify for tax deferral based on each plan participant's local tax requirements. The Limited Retirement Plan allows eligible employees in the U.K. to make tax-deferred contributions to the plan.
 
WeExcept for the period August 1, 2020, to December 31, 2021 where employer contributions were temporarily suspended in light of the then current economic environment, we generally make matching cash contributions to the plans. We matchThese matching contributions were reinstated effective January 1, 2022 whereby 100% of the amount contributed by the employee was matched up to a maximum of 4% of eligible salary, and increased effective January 1, 2023 whereby employee contributions are now matched up to a maximum of 5% of eligible salary. Matching. These matching contributions totaled $12.2 million, $16.7$8.0 million and $18.9$4.7 million for the years ended December 31, 2017, 20162023 and 2015,2022 (Successor), respectively.  Any additional discretionary



contributions made into the plans require approval12.  INCOME TAXES

We generated profits of the Board of Directors and are generally paid in cash.  We recorded additional discretionary contribution provisions of $19.2$30.7 million $39.7 million, $253.4 million and $27.5$373.1 million before income taxes in the U.S. for the years ended December 31, 20162023 and 2015, respectively.  Matching contributions and additional discretionary contributions become vested in 33% increments upon completion of each initial year of service with all contributions becoming fully vested subsequent to achievement of three or more years of service.  We have 1.0 million shares reserved for issuance as matching contributions under the Ensco Savings Plan.

9.  GOODWILL

Our business consists of three operating segments: (1) Floaters, which includes our drillships and semisubmersible rigs, (2) Jackups and (3) Other, which consists of management services on rigs owned by third-parties. Our two reportable segments, Floaters and Jackups, represent our reporting units. We have historically tested goodwill for impairment on an annual basis or when events or changes in circumstances indicate that a potential impairment exists. All of our goodwill was impaired as of2022, eight months ended December 31, 2015.

At the beginning of 2015, our goodwill balance was $276.1 million, net of accumulated impairment of $3.0 billion. During 2015, we recorded non-cash losses on impairment of $192.6 million2021 (Successor), and $83.5 million for the Jackups and Floaters reporting units, respectively, which were included in loss on impairment in our consolidated statement of operations.

As part of our annual 2015 goodwill impairment test, we considered the decline in oil prices, which resulted in significant capital spending reductions by our customers and corresponding deterioration in our forecasted day rates and utilization. Additionally, our stock price declined significantly from $35 at the end of 2014 to below $15 at the end of 2015. We concluded it was more-likely-than-not that the fair values of our reporting units were less than their carrying amounts.

We utilized an income approach that was based on a discounted cash flow model, which included present values of cash flows to estimate the fair value of our reporting units and was based on unobservable inputs that require significant judgments for which there was limited information. The future cash flows were projected based on our estimates of future day rates, utilization, operating costs, capital requirements, growth rates and terminal values. Forecasted day rates and utilization took into account market conditions and our anticipated business outlook.
We compared the estimated fair value of each reporting unit to the fair values of all assets and liabilities within the respective reporting unit to calculate the implied fair value of goodwill and recorded an impairment to goodwill for the difference.

U.S. Tax Reform

U.S. tax reform was enacted on December 22, 2017 and introduced significant changes to U.S. income tax law, including a reduction in the statutory income tax rate from 35% to 21% effective January 1, 2018, a base erosion anti-abuse tax that effectively imposes a minimum tax on certain payments to non-U.S. affiliates and new and revised rules relating to the current taxation of certain income of foreign subsidiaries. We recognized a net tax expense of $16.5 million during the fourth quarter of 2017 in connection with enactment of U.S. tax reform, consisting of a $38.5 million tax expense associated with the one-time transition tax on deemed repatriation of the deferred foreign income of our U.S. subsidiaries, a $17.3 million tax expense associated with revisions to rules over the taxation of income of foreign subsidiaries, a $20.0 million tax benefit resulting from the re-measurement of our deferred tax assets and liabilities as of December 31, 2017 to reflect the reduced tax rate and a $19.3 million tax benefit resulting from adjustments to the valuation allowance on deferred tax assets.

Due to the timing of the enactment of U.S. tax reform and the complexity involved in applying its provisions, we have made reasonable estimates of its effects and recorded such amounts in our consolidated financial statements as of December 31, 2017 on a provisional basis. As we continue to analyze applicable information and data, and interpret any additional guidance issued by the U.S. Treasury Department, the Internal Revenue Service and others, we may make adjustments to the provisional amounts throughout the one-year measurement period as provided by Staff Accounting Bulletin No. 118. Our accounting for the enactment of U.S. tax reform will be completed during 2018 and any adjustments we recognize could be material. The ongoing impact of U.S. tax reform may result in an increase in our consolidated effective income tax rate in future periods.

The realization of substantially all of our deferred tax assets is dependent onupon generating sufficient taxable income during future periods in various jurisdictions in which we operate. We rely on projected taxable income from both current and future drilling contracts for the recognition of deferred tax assets. Realization of certain of our deferred tax assets is not assured. We recognize a valuation allowance for deferred tax assets when it is more-likely-than-not that the benefit from the deferred tax asset will not be realized. The amount of deferred tax assets considered realizable could increase or decrease in the near termnear-term if our estimates of future taxable income change.

As of December 31, 2017,2023, we had gross deferred tax assets of $132.3$3.3 billion relating to $14.2 billion of net operating loss ("NOL") carryforwards, $44.7 million forof U.S. foreign tax credits (“FTC”FTCs”), and $187.1$123.4 million related to $844.1 millionof net operating loss (“NOL”)U.S., Luxembourg and U.K. interest limitation carryforwards, which can be used to reduce our income taxes payable in future years. The FTCs expire between 2022 and 2038.  NOL carryforwards, which were generated in various jurisdictions worldwide, include $429.2 million$13.2 billion that do not expire and $414.9 million$1.0 billion that will expire, if not utilized, beginningbetween 2024 and 2040. Deferred tax assets for NOL carryforwards as of December 31, 2023 include $2.4 billion, $607.5 million, $88.6 million, and $78.0 million pertaining to NOL carryforwards in 2018 through 2037.  DueLuxembourg, the United States, Switzerland, and the U.K., respectively. The U.S. FTCs expire between 2024 and 2026. Interest limitation carryforwards generally do not expire. Additionally, as a result of our emergence from bankruptcy, the utilization of certain U.S. deferred tax assets including, but not limited to, NOL carryforwards, FTCs, and interest limitation carryforwards is limited to $0.5 million annually.

We had a $4.2 billion and a $4.7 billion valuation allowance as of December 31, 2023 and 2022, respectively, on deferred tax assets relating to those assets for which we are not more likely than not to realize due to the uncertaintyinability to generate sufficient taxable income in the period prior to expiration and/or of the character necessary to use the benefit of the deferred tax assets. During the years ended December 31, 2023 and 2022, and eight months ended December 31, 2021 (Successor), we recognized a deferred tax benefit of $802.9 million, a deferred tax expense of $1.5 million and a deferred tax benefit of $9.8 million, respectively, associated with changes in deferred tax asset valuation allowances. The deferred tax benefit in 2023 primarily relates to a $799.5 million reduction of our valuation allowance recognized in the fourth quarter of 2023 due changes in the balance of relevant positive and negative evidence considered when assessing the realization of our deferred tax assets in certain operating jurisdictions. After considering the balance of evidence, which included historical financial results, projected earnings, contract backlog, day rates and market outlook, we have a $250.3 milliondetermined that sufficient positive evidence exists to conclude that this portion of the valuation allowance on FTCdeferred tax assets is no longer needed. This reduction in our valuation allowance was partially offset by a net increase of $275.0 million in 2023, primarily relating to deferred tax asset activity during the year attributable to NOLs and NOL carryforwards.future deductible temporary differences for which we are not more than likely not to realize. We intend to continue maintaining a valuation allowance on a substantial portion of our deferred tax assets until there is sufficient evidence to support a reversal of such allowances. The timing and amount of future valuation allowance reductions are subject to future levels of contracting and profitability achieved.



Effective Tax Rate


Ensco plc, our parent company,Valaris Limited is domiciled and resident in the U.K.Bermuda. Our subsidiaries conduct operations and earn income in numerous countries and are subject to the laws of taxing jurisdictions within those countries. The income of our non-Bermuda subsidiaries is not subject to Bermuda taxation. Legacy Valaris was domiciled and resident in the U.K. The income of our non-U.K. subsidiaries iswas generally not subject to U.K. taxation.

Income tax rates imposedand taxation systems in the tax jurisdictions in which our subsidiaries conduct operations vary as does the tax baseand our subsidiaries are frequently subjected to which the rates are applied.minimum taxation regimes. In some cases,jurisdictions, tax rates may be applicable toliabilities are based on gross revenues, statutory or negotiated deemed profits or other bases utilized under local tax laws,factors, rather than on net income, and our subsidiaries are frequently unable to net income.realize tax benefits when they operate at a loss. Accordingly, during periods of declining profitability, our income tax expense may not decline proportionally with income, which could result in higher effective income tax rates. Furthermore, we will continue to incur income tax expense in periods in which we operate at a loss.

Our drilling rigs frequently move from one taxing jurisdiction to another to perform contract drilling services. In some instances, the movement of drilling rigs among taxing jurisdictions will involve the transfer of ownership of the drilling rigs among our subsidiaries. As a result of frequent changes in the taxing jurisdictions in which our drilling rigs are operated and/or owned, changes in profitability levels and changes in tax laws, our annual effective income tax rate may vary substantially from one reporting period to another. In periods of declining profitability, our income tax expense may not decline proportionally with income, which could result in higher effective income tax rates. Further, we may continue to incur income tax expense in periods in which we operate at a loss.

The changes in our consolidated effective income tax rate excluding discrete tax items during the three-year period result primarily from changes in the relative components of our earnings from the various taxing jurisdictions in which our drilling rigs are operated and/or owned and differences in tax rates in such taxing jurisdictions.




Unrecognized Tax Benefits


Our tax positions are evaluated for recognition using a more-likely-than-not threshold, and those tax positions requiring recognition are measured as the largest amount of tax benefit that is greater than 50% likely of being realized upon effective settlement with a taxing authority that has full knowledge of all relevant information.

Tax Assessments

In October 2016,December 2023, one of our Luxembourg subsidiaries received tax assessments for fiscal years 2019, 2020, 2021 and 2023 and a demand of payment from the FASB issued Accounting Standards Update 2016-16, Income Taxes (Topic 740): Intra-Entity TransfersLuxembourg tax authorities for an aggregate of Assets Other Than Inventory (“Update 2016-16”)approximately €115.0 million (approximately $127.0 million converted at current period-end exchange rates), which requires entitiesincluding interest. In February 2024, we subsequently received notice from the Luxembourg tax authorities reducing the amount attributable to recognize the income2023 payment demand by approximately €55.0 million resulting in a revised aggregate tax consequencesdemand of an intra-entity transferapproximately €60.0 million. We have recorded a liability for uncertain tax positions of an asset other than inventory whenapproximately €60.0 million (approximately $66.0 million converted at current period-end exchange rates) in the transaction occurs as opposed


fourth quarter of 2023 related to deferringthe assessments for the 2019-2021 tax consequencesyears. We are vigorously contesting these assessments, including the validity and amortizing them into future periods. We adopted Update 2016-16 on a modified retrospective basis effective January 1, 2017. As a resultamount; however, the outcome of modified retrospective application, we reduced prepaid taxes on intercompany transfers of propertysuch challenges and related deferred tax liabilities resultingadministrative proceedings and appeals cannot be predicted with certainty. An unfavorable outcome could result in the recognition of a cumulative-effect reduction in retained earnings of $14.1 millionmaterial impact on our consolidated balance sheetfinancial position, operating results and cash flows.

During 2019, the Australian tax authorities issued aggregate tax assessments totaling approximately A$101.0 million (approximately $69.0 million converted at the current period-end exchange rate) 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$42.0 million payment (approximately $29.0 million at then-current exchange rates) to the Australian tax authorities to litigate the assessment. We have an $18.8 million liability for uncertain tax positions relating to these assessments as of January 1, 2017.
As of December 31, 2016,2023. We believe our tax returns are materially correct as filed, and we are vigorously contesting these assessments. Although the unamortized balance associatedoutcome of such assessments and related administrative proceedings cannot be predicted with deferred charges for income taxes incurred in connection with intercompany transfers of drilling rigs totaled $33.0 million and was included in other assets, net,certainty, we do not expect these matters to have a material adverse effect on our consolidated balance sheet.

As of December 31, 2016, the unamortized balance associated with the deferred tax liability for reversing temporary differences of transferred drilling rigs totaled $18.9 million, respectively, and was included in other liabilities on our consolidated balance sheet.  Deferred income tax benefit for the years ended December 31, 2016 and 2015 included benefits of $2.3 million and $1.8 million, respectively, of amortization of deferred reversing temporary differences associated with intercompany transfers of drilling rigs.

Undistributed Earnings
    
Dividend income received by Ensco plcValaris Limited from its subsidiaries is exempt from U.K.Bermuda taxation. We do not provide deferred taxes on undistributed earnings of certain subsidiaries because our policy and intention is to reinvest such earnings indefinitely. EachAs of December 31, 2023, the aggregate undistributed earnings of the subsidiaries for which we maintain sucha policy has sufficient net assets, liquidity, contract backlog and/and intention to reinvest earnings indefinitely totaled $298.2 million. Should we make a distribution from these subsidiaries in the form of dividends or other financial resources availableotherwise, we would be subject to meet operational and capital investment requirements, which allows us to continue to maintain our policy of reinvesting the undistributed earnings indefinitely.

The deferred foreignadditional income of our U.S. subsidiaries was deemed to be repatriated under U.S. tax reform, and we recognized a $38.5 million tax expense associated with the repatriation on a provisional basis. We are currently analyzing the potential non-U.S. tax liabilities that would arise on an actual repatriation, and we have not changed our prior assertion regarding the foreign earnings of our U.S. subsidiaries. We will record the tax effects of any change in our prior assertion upon completion of our analysis during the measurement period provided in Staff Accounting Bulletin No. 118 and disclose anytaxes. The unrecognized deferred tax liability associated with our assertion, if practicable.

11.  DISCONTINUED OPERATIONS

Our business strategy has beenrelated to focus on ultra-deepwater floater and premium jackup operations and de-emphasize other assets and operations that arethese undistributed earnings was not part of our long-term strategic plan or that no longer meet our standards for economic returns. Consistent with this strategy, we sold nine jackup rigs, three dynamically positioned semisubmersible rigs, two moored semisubmersible rigs and two drillships during the three-year period ended December 31, 2017. We are marketing for sale ENSCO 7500, which was classified as held-for-sale in our consolidated financial statementspracticable to estimate as of December 31, 2017.2023.


FollowingTax Legislation

The Organization for Economic Co-operation and Development has issued Pillar Two model rules introducing a new global minimum tax of 15% applied on a country-by-country basis intended to be effective on January 1, 2024. Numerous jurisdictions are actively considering changes to existing tax laws or have proposed or enacted new laws to align with the Merger,recommendations and guidelines under Pillar Two. There remains uncertainty as to the final Pillar Two model rules and we will continue to focusmonitor global legislative action related to this initiative. Additionally, Bermuda recently enacted the Corporate Income Tax Act 2023 on December 27, 2023 (the “CIT Act”) which stipulates a tax on 15% of the net income of certain Bermuda constituent entities (as determined in accordance with the CIT Act, including after adjusting for any relevant foreign tax credits applicable to the Bermuda constituent entities). No tax is chargeable under the CIT Act until tax years starting on or after January 1, 2025. While we are still closely monitoring developments of these rules and evaluating the potential impact on future periods, we do not expect they will have a significant impact on our fleet management strategy in light of the new composition of our rig fleet and are reviewing our fleet composition as we continue positioning Ensco for the future. As part of this strategy, we may act opportunistically from time to time to monetize assets to enhance shareholder value and improve our liquidity profile, in addition to selling or disposing of older, lower-specification or non-core rigs.

Prior to 2015, individual rig disposals were classified as discontinued operations once the rigs met the criteria to be classified as held-for-sale. The operatingfinancial results of the rigs through the date the rig was sold as well as the gain or loss on sale were included in results from discontinued operations, net, in our consolidated statement of operations.


Net proceeds from the sales of the rigs were included in investing activities of discontinued operations in our consolidated statement of cash flows in the period in which the proceeds were received.near term.


During 2015, we adopted the Financial Accounting Standards Board’s Accounting Standards Update 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity ("Update 2014-08"). Under the new guidance, only disposals representing a strategic shift in operations should be presented as discontinued operations. As a result, individual assets that are classified as held-for-sale beginning in 2015 are not reported as discontinued operations and their operating results and gain or loss on sale of these rigs are included in contract drilling expense in our consolidated statements of operations. Rigs that were classified as held-for-sale prior to 2015 continue to be reported as discontinued operations.

128
During 2014, we committed to a plan to sell various non-core floaters and jackups. The operating results for these rigs and any related gain or loss on sale were included in income (loss) from discontinued operations, net, in our consolidated statements of operations. ENSCO 7500 continues to be actively marketed for sale and was classified as held-for-sale on our December 31, 2017 consolidated balance sheet.

The joint venture partners intend for the remaindernewbuild jackup rigs to be financed out of available cash on hand and from ARO's operations and/or funds available from third-party financing. In January 2020, ARO paid 25% of the Pemex contract, which ended in July 2015, less than one yearpurchase price from the date of sale. Our management services following the sale did not constitute significant ongoing involvement and therefore, the rig's operating results through the term of the contract and losscash on sale were included in results from discontinued operations, net, in our consolidated statements of operations.

(1) The rigs' operating results were reclassified to discontinued operations in our consolidated statements of operationshand for each of the two newbuilds, and in October 2023, entered into a $359.0 million term loan to finance the remaining payments due upon delivery and for general corporate purposes. The term loan matures in eight years following the related drawdown under the term loan and requires equal quarterly amortization payments during the term, with a 50% balloon payment due at maturity. The term loan bears interest based on the three-month SOFR plus a margin ranging from 1.25% to 1.4%. Our Notes Receivable from ARO are subordinated and junior in right of payment to ARO’s term loan. In the three-year period ended December 31, 2017event ARO has insufficient cash 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. Beginning with the delivery of the second newbuild, each partner's commitment shall be reduced by the lesser of the actual cost of each newbuild rig or $250.0 million, on a proportionate basis.

On a quarterly basis, we reassess the fair values of our held-for-sale rigs to determine whether any adjustments to the carrying values are necessary.  We recorded a non-cash loss on impairment totaling $120.6 million (net of tax benefits of $28.0 million), for the year ended December 31, 2015, as a result of declines in the estimated fair values of our held-for-sale rigs. The loss on impairment was included in loss from discontinued operations, net, in our consolidated statement of operations for the year ended December 31, 2015. We measured the fair value of held-for-sale rigs by applying a market approach, which was based on an unobservable third-party estimated price that would be received in exchange for the assets in an orderly transaction between market participants.

Income tax benefit from discontinued operations for the years ended December 31, 2017 and 2016 included $2.1 million and $10.2 million of discrete tax benefits, respectively.

Debt and interest expense are not allocated to our discontinued operations.

12.  COMMITMENTS AND CONTINGENCIES

Leases

We are obligated under leases for certain of our offices and equipment.  Rental expense relating to operating leases was $29.0 million, $32.6 million and $50.9 million during the years ended December 31, 2017, 2016 and 2015, respectively. Future minimum rental payments under our noncancellable operating lease obligations are as follows: $22.6 million during 2018; $15.3 million during 2019; $11.7 million during 2020; $10.5 million during 2021; $10.8 million during 2022 and $24.6 million thereafter.

Capital Commitments

The following table summarizes the cumulative amount of contractual payments madecredit outstanding as of December 31, 2017 for2023 totaled $128.8 million and are issued under facilities provided by various banks and other financial institutions, but none were issued under the Credit Agreement. Obligations under these letters of credit are not normally called, as we typically comply with the underlying performance requirements. As of December 31, 2023, we had collateral deposits in the amount of $12.6 million with respect to these agreements.

Patent Litigation

In December 2022, a subsidiary of Transocean Ltd. commenced an arbitration proceeding against us alleging breach of a license agreement related to certain dual-activity drilling patents. We are unable to estimate our rigs under constructionpotential exposure, if any, to the proceeding at this time but do not believe that our ultimate liability, if any, resulting from this proceeding will have a material effect on our consolidated financial condition, results of operations or cash flows. We do not believe that we have breached the license agreement and estimated timing of our remaining contractual payments (in millions): intend to defend ourselves vigorously against this claim.

Cumulative paid represents the aggregate amount of contractual payments made from commencement of the construction agreement through December 31, 2017. Contractual payments made by Atwood prior to the Merger for ENSCO DS-13 (formerly Atwood Admiral) and ENSCO DS-14 (formerly Atwood Archer) are excluded.



(2)
Total commitments are based on fixed-price shipyard construction contracts, exclusive of costs associated with commissioning, systems integration testing, project management, holding costs and interest.

(3)
In January 2018, we paid $207.4 million of the $218.3 million unpaid balance. The remaining $10.9 million is due upon delivery. The $207.4 million milestone payment was invoiced and included in accounts payable - trade as of December 31, 2017 on our consolidated balance sheet.

(4)
The remaining milestone payments for ENSCO DS-13 and ENSCO DS-14 bear interest at a rate of 4.5% per annum, which accrues during the holding period until delivery. Delivery is scheduled for September 2019 and June 2020 for ENSCO DS-13 and ENSCO DS-14, respectively. Upon delivery, the remaining milestone payments and accrued interest thereon may be financed through a promissory note with the shipyard for each rig. The promissory notes will bear interest at a rate of 5% per annum with a maturity date of December 31, 2022 and will be secured by a mortgage on each respective rig. The remaining milestone payments for ENSCO DS-13 and ENSCO DS-14 are included in the table above in the period in which we expect to take delivery of the rig. However, we may elect to execute the promissory notes and defer payment until December 2022.

The actual timing of these expenditures may vary based on the completion of various construction milestones, which are, to a large extent, beyond our control.

Brazil Internal InvestigationAdministrative Proceeding


Pride International LLC, formerly Pride International, Inc.In July 2023, we received notice of an administrative proceeding initiated against us in Brazil. Specifically, the Federal Court of Accounts ("TCU") is seeking from us, Samsung Heavy Industries (“Pride”SHI”), and others, on a company we acquiredjoint and several basis, a total of approximately BRL 601.0 million (approximately $124.0 million at the current quarter-end exchange rates) in 2011, commenced drilling operationsdamages that TCU asserts arose from the overbilling to Petrobras in Brazil2015 in 2001. In 2008, Pride entered into arelation to the drilling services agreement with Petrobras for VALARIS DS-5 (the "DSA") for ENSCO DS-5, a drillship ordered from Samsung Heavy Industries, a shipyard in South Korea ("SHI"“DSA”). BeginningAs fully disclosed in 2006, Pride conductedour prior periodic compliance reviewsreports, the DSA was previously the subject of its business with Petrobras, and, after the acquisition of Pride, Ensco conducted similar compliance reviews.

We commenced a compliance review in early 2015 after the release of media reports regarding ongoing(1) investigations of various kickback and bribery schemes in Brazil involving Petrobras. While conducting our compliance review, we became aware of an internal audit report by Petrobras alleging irregularities in relation to the DSA. Upon learning of the Petrobras internal audit report, our Audit Committee appointed independent counsel to lead an investigation into the alleged irregularities. Further, in June and July 2015, we voluntarily contacted the SEC and the DOJ, respectively,U.S Department of Justice, each of which closed their investigation of us in 2018 without any enforcement action, (2) an arbitration proceeding against SHI in which we prevailed resulting in SHI making a $200.0 million cash payment to advise them of this matter and of our Audit Committee’s investigation. Independent counsel, under the direction of our Audit Committee, has substantially completed its investigation by reviewing and analyzing available documents and correspondence and interviewing current and former employees involved in the DSA negotiations and the negotiation of the ENSCO DS-5 construction contract with SHI (the "DS-5 Construction Contract").

To date, our Audit Committee has found no credible evidence that Pride or Ensco or any of their current or former employees were aware of or involved in any wrongdoing, and our Audit Committee has found no credible evidence linking Ensco or Pride to any illegal acts committed by our former marketing consultant who provided services to Pride and Ensco in connection with the DSA. We, through independent counsel, have continued to cooperate with the SEC and DOJ, including providing detailed briefings regarding our investigation and findings and responding to inquiries as they arise. We entered into a one-year tolling agreement with the DOJ that expiredus in December 2016.2019, and (3) a settlement with Petrobras normalizing our business relations in August 2018. We extended our tolling agreement withplan to vigorously defend ourselves against the SEC for 12 months until March 2018.

Subsequent to initiating our Audit Committee investigation, Brazilian court documents connected to the prosecution of former Petrobras directors and employees as well as certain other third parties, including our former marketing consultant, referenced the alleged irregularities cited in the Petrobras internal audit report. Our former marketing consultant has entered into a plea agreement with the Brazilian authorities. On January 10, 2016, Brazilian authorities filed an indictment against a former Petrobras director. This indictment states that the former Petrobras director received bribes paid out of proceeds from a brokerage agreement entered into for purposes of intermediating a drillship construction contract between SHI and Pride, which we believe to be the DS-5 Construction Contract. The


parties to the brokerage agreement were a company affiliated with a person acting on behalf of the former Petrobras director, a company affiliated with our former marketing consultant, and SHI. The indictment alleges that amounts paid by SHI under the brokerage agreement ultimately were used to pay bribes to the former Petrobras director. The indictment does not state that Pride or Ensco or any of their current or former employees were involved in the bribery scheme or had any knowledge of the bribery scheme.

On January 4, 2016, we received a notice from Petrobras declaring the DSA void effective immediately. Petrobras’ notice alleges that our former marketing consultant both received and procured improper payments from SHI for employees of Petrobras and that Pride had knowledge of this activity and assisted in the procurement of and/or facilitated these improper payments. We disagree with Petrobras’ allegations. See "DSA Dispute" below for additional information.
In August 2017, one of our Brazilian subsidiaries was contactedallegations made by the Office of the Attorney General for the Brazilian state of ParanáTCU. Because these proceedings are in connection with a criminal investigation procedure initiated against agents of both SHI and Pride in relationtheir initial stages, we are unable to the DSA.  The Brazilian authorities requested information regarding our compliance program and the findings of our internal investigations. We are cooperating with the Office of the Attorney General and have provided documents in response to their request.  We cannot predict the scope or ultimate outcome of this procedure or whether any other governmental authority will open an investigation into Pride’s involvement in this matter, or if a proceeding were opened, the scope or ultimate outcome of any such investigation. If the SEC or DOJ determines that violations of the FCPA have occurred, or if any governmental authority determines that we have violated applicable anti-bribery laws, they could seek civil and criminal sanctions, including monetary penalties, against us, as well as changes to our business practices and compliance programs, any of which could have a material adverse effect on our business and financial condition. Although our internal investigation is substantially complete, we cannot predict whether any additional allegations will be made or whether any additional facts relevant to the investigation will be uncovered during the course of the investigation and what impact those allegations and additional facts will have on the timing or conclusions of the investigation. Our Audit Committee will examine any such additional allegations and additional facts and the circumstances surrounding them.

DSA Dispute

As described above, on January 4, 2016, Petrobras sent a notice to us declaring the DSA void effective immediately, reserving its rights and stating its intention to seek any restitution to which it may be entitled. We disagree with Petrobras’ declaration that the DSA is void. We believe that Petrobras repudiated the DSA and have therefore accepted the DSA as terminated on April 8, 2016 (the "Termination Date"). At this time, we cannot reasonably determine the validity of Petrobras' claim or the range ofestimate our potential exposure, if any. As a result, there can be no assurance as to how this dispute will ultimately be resolved.
We did not recognize revenue for amounts owed to us under the DSA from the beginning of the fourth quarter of 2015 through the Termination Date, as we concluded that collectability of these amounts was not reasonably assured. Additionally, our receivables from Petrobras related to the DSA from prior to the fourth quarter of 2015 are fully reserved in our consolidated balance sheet as of December 31, 2017 and 2016 . In August 2016, we initiated arbitration proceedings in the U.K. against Petrobras seeking payment of all amounts owed to us under the DSA, in addition to any, other amounts to which we are entitled, and intend to vigorously pursue our claims. Petrobras subsequently filed a counterclaim seeking restitution of certain sums paid under the DSA less value received by Petrobras under the DSA. There can be no assurance as to how this arbitration proceeding will ultimately be resolved.

In November 2016, we initiated separate arbitration proceedings in the U.K. against SHI for any losses we incur in connection with the foregoing Petrobras arbitration. SHI subsequently filed a statement of defense disputing our claim. In January 2018, the arbitration tribunal for the SHI matter issued an award on liability fully in Ensco’s favor.  SHI is liable to us for $10 million or damages that we can prove.  As the losses suffered by us will depend in part on the outcome of the Petrobras arbitration described above, the amount of damages to be paid by SHI will be determined after the conclusion of the Petrobras arbitration.  We are unable to estimate the ultimate outcome of recovery for damages at this time.

Other Matters


In addition to the foregoing, we are named defendants or parties in certain other lawsuits, claims or proceedings incidental to our business and are involved from time to time as parties to governmental investigations or proceedings, including matters related to taxation, arising in the ordinary course of business. Although the outcome of such lawsuits or other proceedings cannot be predicted with certainty and the amount of any liability that could arise with respect to such lawsuits or other proceedings cannot be predicted accurately, we do not expect these matters to have a material adverse effect on our financial position, operating results and cash flows.

We have operating leases for office space, facilities, equipment, employee housing and certain rig berthing facilities. For all asset classes, except office space, we account for the ordinary courselease component and the non-lease component as a single lease component. Short-term leases with a term of business with customersone year or less are not recorded on the Consolidated Balance Sheet. Our leases have remaining lease terms of less than one month to eight years, some of which include options to extend. The lease term used for calculating our right-of-use assets and others,lease liabilities is determined by considering the non-cancelable lease term, as well as any extension options that we have entered into lettersare reasonably certain to exercise.

During 2017, the net change in operating assets and liabilities declined by $75.2 million as compared to the prior year. The net change during 2017 was primarily due to a decline in accounts receivable due to lower revenues from contract drilling services, partially offset by an increase in prepaid taxes primarily due to the U.S. tax reform and a decline in liabilities related to lower operating levels across the fleet.

During 2016, the net change in operating assets and liabilities increased by $27.1 million as compared to the prior year. The net change during 2016 was primarily due to a decline in accounts receivable related to lower revenues from contract drilling services and a decline in prepaid taxes and other assets due to collections during the year, partially offset by a decline in liabilities related to lower operating levels across the fleet.

Concentration of Risk


Credit Risk -We are exposed to credit risk relating to our receivables from customers, our cash and cash equivalents and investmentsreceivables from customers. Our cash and our usecash equivalents are primarily held by various well-capitalized and credit-worthy financial institutions. We monitor the credit ratings of derivatives in connection withthese institutions and limit the managementamount of foreign currency exchange rate risk.exposure to any one institution and therefore, do not believe a significant credit risk exists for these balances. We mitigate our credit risk relating to receivables from customers, which consist primarily of major international, government-owned and independent oil and gas companies, by performing ongoing credit evaluations. We also maintain reserves for potential credit losses, which generally have been within our expectations. We mitigate our credit risk relating to cash and investments by focusing on diversification and quality of instruments. Cash equivalents and short-term investments consist of a portfolio of high-grade instruments. Custody of cash and cash equivalents and short-term investments is maintained at several well-capitalized financial institutions, and we monitor the financial condition of those financial institutions.  


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 ISDA Master Agreements, which include provisions for a legally enforceable master netting agreement, with our derivative counterparties. See "Note 6Customer Concentration - Derivative Instruments" for additional information on our derivative activity.

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.

Item 9A.  Controls and Procedures


CONCLUSION REGARDING THE EFFECTIVENESS OF DISCLOSURE CONTROLS AND PROCEDURES


Evaluation of Disclosure Controls and Procedures – We have established disclosure controls and procedures to ensure that the information required to be disclosed by us in the reports that we file under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms and that such information is accumulated and made known to the officers who certify the Company’s financial reports and to other members of senior management and the board of directors as appropriate to allow timely decisions regarding required disclosure.

Based on their evaluation as of the end of the period covered by this Annual Report on Form 10-K, our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has concluded that our disclosure controls and procedures, as defined in Rule 13a-1513a-15(e) and 15d-15(e) under the Exchange Act, are effective.

During the fiscal quarter ended December 31, 2017, thereChanges in Internal Controls – There were no material changes in our internal control over financial reporting during the quarter ended December 31, 2023 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
Management's assessment of the effectiveness of the Company's internal control over financial reporting as of December 31, 2017 excluded the internal control over financial reporting of Atwood Oceanics, Inc. representing total assets of $2.0 billion and total revenues of $23.3 million included in the consolidated financial statements of Ensco plc and subsidiaries as of and for the year ended December 31, 2017.
