PART I
Item 1. Business.
Overview
Noble Corporation plc, a public limited company incorporated under the laws of England and Wales (“Noble-UK”), is a leading offshore drilling contractor for the oil and gas industry. We provide contract drilling services to the international oil and gas industry with our global fleet of mobile offshore drilling units. We focus on a balanced, high-specification fleet of floating and jackup rigs and the deployment of our drilling rigs in oil and gas basins around the world. Noble and its predecessors have been engaged in the contract drilling of oil and gas wells since 1921.
On July 31, 2020 (the “Petition Date”), our former parent company, Noble Holding Corporation plc (formerly known as Noble Corporation plc), a public limited company incorporated under the laws of England and Wales (“Legacy Noble” or the “Predecessor”), and certain of its subsidiaries, including Finco, filed voluntary petitions in the United States Bankruptcy Court for the Southern District of Texas (the “Bankruptcy Court”) seeking relief under chapter 11 of title 11 of the United States Code (the “Bankruptcy Code”). On September 4, 2020, the Debtors filed with the Bankruptcy Court the Joint Plan of Reorganization of Noble Corporation plc and its Debtor Affiliates, which was subsequently amended on October 8, 2020 and October 13, 2020 and modified on November 18, 2020 (as amended, modified or supplemented, the “Plan”), and the related disclosure statement (the “Disclosure Statement”). On September 24, 2020, six additional subsidiaries of Legacy Noble (together with Legacy Noble and its subsidiaries that filed on the Petition Date, as the context requires, the “Debtors”) filed voluntary petitions in the Bankruptcy Court. The chapter 11 proceedings were jointly administered under the caption Noble Corporation plc, et al. (Case No. 20-33826) (the “Chapter 11 Cases”). On November 20, 2020, the Bankruptcy Court entered an order confirming the Plan. In connection with the Chapter 11 Cases and the Plan, on and prior to the Effective Date (as defined herein), Legacy Noble and certain of its subsidiaries effectuated certain restructuring transactions pursuant to which Legacy Noble formed Noble as an indirect wholly-owned subsidiary of Legacy Noble and transferred to Noble substantially all of the subsidiaries and other assets of Legacy Noble. On February 5, 2021 (the “Effective Date”), the Plan became effective in accordance with its terms and the Debtors emerged from the Chapter 11 Cases. See Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations— Chapter 11 Proceedings and Going Concern” for a description of the events that occurred on the Effective Date, including the issuance of the ordinary shares of Noble (“New Shares”), the Tranche 1 Warrants, the Tranche 2 Warrants and the Tranche 3 Warrants (each as defined herein). In accordance with the Plan, Legacy Noble and its remaining subsidiary will in due course be wound down and dissolved in accordance with applicable law.
Finco was an indirect, wholly-owned subsidiary of Legacy Noble prior to the Effective Date and has been a direct, wholly-owned subsidiary of Noble, our parent company, since the Effective Date. Noble’s principal asset is all of the shares of Finco. Finco has no public equity outstanding. The consolidated financial statements of Noble include the accounts of Finco, and Noble conducts substantially all its business through Finco and its subsidiaries.
Noble is the successor issuer to Legacy Noble for purposes of and pursuant to Rule 15d-5 of the Exchange Act. References to the “Company,” “we,” “us” or “our” in this Annual Report are to Noble, together with its consolidated subsidiaries, when referring to periods following the Effective Date, and to Legacy Noble, together with its consolidated subsidiaries, when referring to periods prior to the Effective Date.
Contract Drilling Services
We report our contract drilling operations as a single reportable segment, Contract Drilling Services, which reflects how we manage our business. The mobile offshore drilling units comprising our offshore rig fleet operate in a global market for contract drilling services and are often redeployed to different regions due to changing demands of our customers, which consist primarily of large, integrated, independent and government-owned or controlled oil and gas companies throughout the world. As of February 20, 2018, our 28-rig fleet consisted of eight drillships, six semisubmersibles and 14 jackups.
For additional information on the specifications of our fleet, see Part I, Item 2, “Properties— Drilling Fleet.” At December 31, 2017, our fleet was located in Canada, Far East Asia, the Middle East, the North Sea, Oceania, South America and the Gulf of Mexico. Noble and its predecessors have been engaged in the contract drilling of oil and gas wells since 1921.
Noble Corporation, a Cayman Islands company (“Noble-Cayman”), is an indirect, wholly-owned subsidiary of Noble-UK, our publicly-traded parent company. Noble-UK’s principal asset is all of the shares of Noble-Cayman. Noble-Cayman has no public equity outstanding. The consolidated financial statements of Noble-UK include the accounts of Noble-Cayman, and Noble-UK conducts substantially all its business through Noble-Cayman and its subsidiaries.
On August 1, 2014, Noble-UK completed the separation and spin-off of a majority of its standard specification offshore drilling business (the “Spin-off”) through a pro rata distribution of all the ordinary shares of its wholly-owned subsidiary, Paragon Offshore plc (“Paragon Offshore”), to the holders of Noble’s ordinary shares. Our shareholders received one share of Paragon Offshore for every three shares of Noble owned as of July 23, 2014, the record date for the distribution. Through the Spin-off, we disposed of most of our standard specification drilling units and related assets, liabilities and business. Prior to the Spin-off, Paragon Offshore issued approximately $1.7 billion of long-term debt, the proceeds of which were used to repay certain amounts outstanding under our commercial paper program. The results of operations for Paragon Offshore prior to the Spin-off date and incremental Spin-off related costs have been classified as discontinued operations for all periods presented in this Annual Report on Form 10-K.
For additional information regarding the Spin-off and our current relationship with Paragon Offshore, see Part I, Item 1A, "Risk Factors" and Part II, Item 8, “Financial Statements and Supplementary Data, Note 14— Commitments and Contingencies.”
Business Strategy
Our goal is to be the preferred offshore drilling contractor for the oil and gas industry based upon the following core principles:
operate in a manner that provides a safe working environment for our employees and contractors while protecting the environment and our assets;
provide an attractive investment vehicle; and
deliver superior customer service through a diverse and technically advanced fleet operated by proficient crews.
Our business strategy focuses on a balanced, high-specification fleet of floating and jackup rigs and the deployment of our drilling rigs in oil and gas basins around the world.
We have expanded our drilling and fleet through our newbuild program. We took delivery of our last remaining newbuild, the heavy-duty, harsh environment jackup, the Noble Lloyd Noble, in July 2016. The Noble Lloyd Noble commenced operations in November 2016 under a four-year contract in the North Sea. Although we plan to prioritize capital preservation and liquidity based on current market conditions, from time to time we will also continue to evaluate opportunities to enhance our fleet, particularly focusing on higher specification rigs, to execute the increasingly complex drilling programs required by our customers.
Drilling Services
We typically employ eachprovide contract drilling unitservices under an individual contract.contract, on a dayrate basis. Although the final terms of the contracts result from negotiations with our customers, many contracts are awarded based upon a competitive bidding process. Our drilling contracts generally contain the following terms:
contract duration extending over a specific period of time or a period necessary to drill a defined number of wells;
payment of compensation to us (generally in U.S.US Dollars although some customers, typically national oil companies, require a part of the compensation to be paid in local currency) on a “daywork” basis, so that we receive a fixed amount for each day (“dayrate”) that the drilling unit is operating under contract (a lower rate or no compensation is payable during periods of


equipment breakdown and repair or adverse weather or in the event operations are interrupted by other conditions, some of which may be beyond our control);
provisions permitting early termination of the contract by the customer (i) if the unit is lost or destroyed, or (ii) if operations are suspended for a specified period of time due to breakdown of equipment or breach of contract;contract or (iii) for convenience;
4


provisions allowing the impacted party to terminate the contract if specified “force majeure” events beyond the contracting parties’ control occur for a defined period of time;
payment by us of the operating expenses of the drilling unit, including labor costs and the cost of incidental supplies;
provisions that allow us to recover certain cost increases from our customers in certain long-term contracts; and
provisions that require us to lower dayrates for documented cost decreases in certain long-term contracts.
The terms of some of our drilling contracts permit the customer to terminate the contract after specified notice periods by tendering contractually specified termination amounts and, in certain cases, without any payment.
Generally, our contracts allow us to recover our mobilization and demobilization costs associated with moving a drilling unit from one regional location to another. When market conditions require us to assume these costs, our operating margins are reduced accordingly. For shorter moves, such as “field moves,” our customers have generally agreed to assume the costs of moving the unit in the form of a reduced dayrate or “move rate” while the unit is being moved. Under current market conditions, we are much less likely to receive full reimbursement of our mobilization and demobilization costs.
Contracts often contain early termination provisions permitting the customer to terminate the contract if the unit is lost or destroyed or if operations are suspended for a specified period of time due to breakdown of equipment or breach of contract. In addition, the terms of our drilling contracts permit the customer to terminate the contract after specified notice periods by tendering contractually specified termination amounts and, in often cases, without any payment or a modest payment.
During periods of depressed market conditions, such as the one we are currently experiencing,experienced for a number of years, our customers may attempt to renegotiate or repudiate their contracts with us although we seek to enforce our rights under our contracts. The renegotiations may include changes to key contract terms, such as pricing, termination and risk allocation. 
For a discussion of our backlog of commitments for contract drilling services, please read Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations— Contract Drilling Services Backlog.”
Drilling Fleet
Noble is a leading offshore drilling contractor for the oil and gas sector. Noble owns and operates one of the most modern, versatile and technically advanced fleets of mobile offshore drilling units in the offshore drilling industry. Noble provides, through its subsidiaries, contract drilling services with a fleet of 19 offshore drilling units, consisting of seven floaters and 12 jackups at the date of this report, focused largely on ultra-deepwater and high-specification drilling opportunities in both established and emerging regions worldwide. Each type of drilling rig is described further below. Several factors determine the type of unit most suitable for a particular job, the most significant of which include the water depth and the environment of the intended drilling location, whether the drilling is being done over a platform or other structure, and the intended well depth. At December 31, 2020, our fleet was located in Far East Asia, the Middle East, the North Sea, Oceania, South America and the US Gulf of Mexico.
Floaters
Our floating fleet consists of the following:
    A drillship is a type of floating drilling unit that is based on the ship-based hull of the vessel and equipped with modern drilling equipment that gives it the capability of easily transitioning from various worldwide locations and carrying high capacities of equipment while being able to drill ultra-deepwater oil and gas wells in up to 12,000 feet of water. Drillships can stay directly over the drilling location without anchors in open seas using a dynamic positioning system (“DPS”), which coordinates position references from satellite signals and acoustic seabed transponders with the drillship's six to eight thrusters to keep the ship directly over the well that is being drilled. Drillships are selected to drill oil and gas wells for programs that require a high level of simultaneous operations, where drilling loads are expected to be high, or where there are occurrences of high ocean currents, where the drillship's hull shape is the most efficient. Noble's fleet consists of six drillships capable of water depths from 10,000 feet to 12,000 feet.
    Semisubmersible drilling units are designed as a floating drilling platform incorporating one or several pontoon hulls, which are submerged in the water to lower the center of gravity and make this type of drilling unit exceptionally stable in the open sea. Semisubmersible drilling units are generally categorized in terms of the water depth in which they are capable of operating, from the mid-water range of 300 feet to 4,000 feet, the deepwater range of 4,000 feet to 7,500 feet, to the ultra-deepwater range of 7,500 feet to 12,000 feet as well as by their generation, or date of construction. This type of drilling unit typically exhibits excellent stability characteristics, providing a stable platform for drilling in even rough seas. Semisubmersible drilling units hold their position over the drilling location using either an anchored mooring system or a DPS and may be self-propelled. Noble’s fleet consists of one moored ultra-deepwater semisubmersible drilling unit.
5


Jackups
Noble’s fleet of modern, high-specification jackup drilling units gives us the flexibility to provide drilling solutions to our customers who have drilling requirements in the shallower waters of the continental shelf, in depths ranging from less than 100 feet to as deep as 500 feet of water with drilling hookloads up to 2,500,000. Jackup rigs can be used in open water exploration locations, as well as over fixed, bottom-supported platforms. A jackup drilling unit is a towed mobile vessel consisting of a floating hull equipped with three or four legs, which are lowered to the seabed at the drilling location. The hull is then elevated out of the water by the jacking system using the legs to support weight of the hull and drilling equipment against the seabed. Once the hull is elevated to the desired level, or jacked up, the drilling package can be extended out over an existing production platform or the open water location and drilling can commence. Noble’s fleet of 12 jackups varies from two units capable of drilling in up to 375 feet of water to premium and high-specification units capable of drilling in up to 500 feet of water.
The following table presents certain information concerning our offshore fleet at March 10, 2021. We own and operate all of the units included in the table.

Market
The offshore contract drilling industry is a highly competitive and cyclical business. Demand for offshore drilling services is driven by the offshore exploration and development programs of oil and gas operators, which in turn are influenced by many factors, including, but not limited to, the price and price stability of oil and gas, the availability and relative cost of offshore oil and gas resources within the oil and gas portfolio of each operator, general global economic conditions, energy demand, the operator’s strategy toward renewable energy sources, environmental considerations and national oil and gas policy.
In the provision of offshore contract drilling services, competition is largely governed by price but involves numerous other factors as well. Rig availability, location, suitability and technical specifications are the primary factors in determining which rig is qualified for a job, and additional factors are considered when determining which contractor is awarded a job, including experience of the workforce, efficiency, safety performance record, condition of equipment, operating integrity, reputation, industry standing and client relations. In addition to having one of the newest fleets in the industry among our peer companies, we strive to keep our assets well-maintained and technologically competitive.
We maintain a global operational presence and compete in many of the major offshore oil and gas basins worldwide. All our drilling rigs are mobile, and we may mobilize our drilling rigs among regions for a variety of reasons, including to respond to customer requirements. We compete in both the jackup and floating rig market segments, each of which may have different supply and demand dynamics at a given period in time or in different regions.
Since late 2014, the offshore drilling industry has experienced a severe and prolonged downturn driven by a combination of an oversupply of drilling rigs, weak and volatile crude oil prices exacerbated in early 2020 by production level disagreements by OPEC+, reductions in global offshore exploration and development activities, and the impacts of COVID-19.
The global mitigation efforts associated with preventing the spread of COVID-19 have significantly slowed global economic activity, leading to a precipitous drop in oil demand in 2020. As the year progressed, some countries began to ease lock-down restrictions, resulting in an increase in oil demand; however, current demand and near-term demand forecasts still lag pre-COVID-19 demand levels. As the demand imbalance played out during the year, crude price volatility lessened as OPEC+ agreed to production level cuts through early 2021. In early 2021, Brent crude averaged $55-$60 per barrel, up from an average of approximately $40 per barrel in 2020. Despite the current price recovery, uncertainty remains around the current level of oil prices as a result of the on-going effects of COVID-19 and the early stage of global vaccine efforts, as well as the uncertainty surrounding the longevity of the OPEC+ production agreements. Finally, a growing number of the major oil companies, including some of our customers, have signaled increased commitments toward the transition to renewable energy sources. As international majors commit to these renewable energy sources, capital investments could be diverted from longer-term fossil fuel projects, creating even more competition among premium offshore drilling assets.
We believe the convergence of events in 2020 and early 2021 have lengthened an already challenging and slow recovery in our industry. Despite these challenges and demand projections, we believe that oil and gas demand will rebalance and oil and gas will remain an important portion of the world’s energy mix. We expect that the return of stable oil demand and prices coupled with the continued attrition of rigs in the global offshore fleet will bring improved market conditions for our services. Our young and technologically advanced fleet is well positioned to compete as market dynamics improve.

Market
Our operations are geographically dispersed in oil and gas exploration and development areas throughout the world. We may mobilize our drilling rigs between regions for a variety of reasons, including to respond to customer contracting requirements or capture demand in another locale. Demand for our services is, in significant part, a function of the worldwide demand for oil and gas and the global supply of mobile offshore drilling units. In recent years, there has been a significant increase in the number of units, while crude oil prices have declined from approximately $112 per barrel for Brent crude on June 30, 2014 to as low as approximately $30 per barrel in January 2016, before improving to $65 per barrel on February 20, 2018. Our customers have greatly reduced their exploration and development spending and the number of rigs they have under contract since 2014. This combination of increased supply of drilling rigs and reduced demand for such rigs has resulted in falling dayrates and significantly reduced opportunities to re-contract our rigs upon expiry of existing contracts.
The offshore contract drilling industry is a highly competitive and cyclical business characterized by large capital expenditures and high operating and maintenance costs. We compete with other providers of offshore drilling rigs, and some of our competitors may have access to greater financial resources than we do.


In the provision of contract drilling services, competition involves numerous factors. Price competition, rig availability, location and rig suitability and technical specifications are the primary factors in determining which contractor is awarded a job, although other factors are important, including experience of the workforce, efficiency, safety performance record, condition of equipment, operating integrity, reputation, industry standing and client relations. In addition to having one of the newest fleets in the industry among our peer companies, we follow a policy of keeping our equipment well-maintained and technologically competitive. However, our rigs could be made obsolete by the development of new techniques and equipment, regulations or customer preferences.
We compete on a worldwide basis, but competition may vary by region. Demand for offshore drilling equipment also depends on the exploration and development programs of oil and gas companies, which in turn are influenced by many factors, including the price of oil and gas, the financial condition of such companies, general global economic conditions, energy demand, political considerations and national oil and gas policy, many of which factors are beyond our control. In addition, industry-wide shortages of supplies, services, skilled personnel and equipment necessary to conduct our business have historically occurred. While we do not anticipate this being an issue in the current market environment, we cannot assure that any such shortages experienced in the past will not happen again in the future.
EmployeesHuman Capital
At December 31, 2017,2020, we had approximately 2,0001,500 employees, excluding approximately 600800 persons we engaged through labor contractors or agencies. Approximately 8388 percent of our workforce is located offshore. We are not a party to any material collective bargaining agreements, and we consider our employee relations to be satisfactory.
We are fully committed to operating our business with honesty and integrity. Our reputation depends on our directors, officers, employees, and others working on our behalf assuming a personal responsibility for our business conduct. Our compliance program is focused on ensuring adherence with the highest ethical standards and applicable laws and setting the tone for an ethical work environment. Noble’s commitment to a strong compliance culture is fundamental to who we are as a leading offshore drilling contractor. Noble’s Code of Business Conduct and Ethics provides the foundation for our culture and underscores our commitment to our core values of safety, environmental stewardship, honesty and integrity, respect and performance. It also includes our responsibility and commitment to follow all applicable laws as well as our own internal policies, and requires any supplier or third party who works with Noble to comply with similar fundamental principles.
Operating our business in a socially responsible way is integral to who we are. Internally, our employee-focused programs such as recruitment and promotion opportunities, safety and environmental stewardship, and training and continuing education are key to our commitment to the personal and professional growth of our workforce. Externally, our dedication is evidenced by our affiliations and how we contribute to and invest in the communities where we operate.
Recruitment and Promotions. We value a healthy culture of ingenuity and adaptability where everyone has an equal opportunity to thrive. We recognize that an inclusive and diverse workforce is key to the advancement and retention of the best qualified people leading to strong innovation and our continued success. We are committed to a policy of recruitment and promotion based upon job qualifications, performance and merit without discrimination.
Safety and Environmental Stewardship. Noble is committed to delivering excellent health, safety and environmental (“HSE”) performance as part of our business strategy in order to add further value for employees, customers, and shareholders. Safety and environmental stewardship are the cornerstone of who we are, what we stand for and what we do every day to deliver a high-quality operation. All personnel, regardless of job or position onboard our vessels or at any Noble facility, has the authorization and obligation to immediately stop any unsafe act, practice or job that that poses any risk or danger to people or the environment. Noble’s pursuit of exceptional HSE performance begins with our strong corporate culture and by starting SAFE every day: one tour, one task and one person at a time. SAFE is an acronym for the phrase: follow Standards, be Accountable, stay Focused, achieve Excellence. Daily, the crew onboard each rig work together to achieve specific safety and environmental objectives and if all objectives are met, then the day is counted as a SAFE Day. Under our SAFE Day program, in 2020, our rigs achieved the SAFE objectives 98.6% of available days, which is an increase over 2019 performance, and our total recordable incident rate for 2020 decreased 38% from the prior year.
Training and Continuing Education. We place considerable value on the involvementtraining and development of our employees and maintain a practice of keeping them informed on matters affecting them, as well as on the performance of the Company. Accordingly, we conduct formal and informal meetings with employees, maintain a Company intranet website with matters of interest, issue periodic publications of Company activities and other matters of interest, and offer a variety of in-house training, including through NobleAdvances, our state of the artstate-of-the-art training facility in Sugar Land, Texas. When travel became a challenge, we developed and enhanced virtual and worksite training courses, some of which are facilitated through our rig-based leadership and are accredited through the International Association of Drilling Contractors.
We are committed to a policyIn consideration of recruitment and promotion based upon merit without discrimination. Management actively pursues both the employmentnegative impact of disabled persons whenever a suitable vacancy arisesCOVID-19 on our employees, customers, suppliers and the communities in which we operate, as well as associated human rights concerns that may exist in the areas in which we operate, we have taken, and will continue to take, incremental measures to monitor, identify and manage risks associated with the COVID-19 pandemic. Throughout the pandemic, we have continued employmentoperations in support of essential infrastructure in the energy industry while carefully ensuring worker safety. We have been able to maintain operation of our rigs by implementing several mitigations, such as extending crew schedules to offset travel delays due to limitations or restrictions, implementing quarantine measures in advance of persons boarding our rigs to prevent the spread of COVID-19 on board and retrainingenhancing crew health monitoring and response measures to prevent an outbreak on board any of our vessels. We have also continued the operation of our shore-side offices by implementing social distancing programs and implementing staggered rotational schedules for facility employees who become disabled while employed byto reduce the Company. Trainingnumber of persons on site. In addition, we have increased internal contingency planning, protective measures and development is undertaken foremployee communications and reinforced our employee wellness programs with all offshore and shore-side employees including disabled persons.to offset the potential impact on employees both personally and professionally.

Governmental Regulations and Environmental Matters
Political developments and numerous governmental regulations, which may relate directly or indirectly to the contract drilling industry, affect many aspects of our operations. Our contract drilling operations are subject to various laws and regulations in countries in which we operate, including laws and regulations relating to the equipping, supplying and operation of drilling units, environmental dischargesprotection and related recordkeeping, health and safety of personnel, safety management systems, the reduction of atmospheric emissions that contribute to a cumulative effect on the overall air quality and environment (commonly referred to as greenhouse gas emissions to address climate change,gases), currency conversions and repatriation, oil and gas exploration and development, taxation of capital equipment, taxation of offshore earnings and earnings of expatriate personnel, employee benefits and use of local employees, content and suppliers by foreign contractors. A number of countries actively regulate and control the ownership of concessions and companies holding concessions, the exportation of oil and gas and other aspects of the oil and gas industries in their countries. In addition, government actions, including initiatives by the Organization of Petroleum Exporting Countries (“OPEC”),OPEC, may continue to contribute to oil price volatility. In some areas of the world, this government activity has adversely affected the amount of exploration and development work done by oil and gas companies and influenced their need for offshore drilling services, and likely will continue to do so.
The regulations applicable to our operations include provisions that regulate the discharge of materials into the environment or require remediation of contamination under certain circumstances. Many of the countries in whose waters we operate from time to time regulate the discharge of oil and other contaminants in connection with drilling and marine operations. Failure to comply with these laws and regulations, or failure to obtain or comply with permits, may result in the assessment of administrative, civil and criminal penalties, imposition of remedial requirements and the imposition of injunctions to force future compliance. We are also subject to a plea agreement with the U.S. Department of Justice (“DOJ”) in connection with prior operations in Alaska, and any future environmental incidents could have an impact on the plea agreement or related actions that the DOJ or other regulatory agencies may take against us as a result of such an incident. We were granted our motion to terminate the Alaska plea agreement effective March 1, 2018. We have made, and will continue to make, expenditures to comply with environmental requirements. We do not believe that our compliance with such requirements will have a material adverse effect on our results of operations, our competitive position or materially increase our capital expenditures. Although these requirements impact the oil and gas and energy services industries, generally they do not appear to affect us in any material respect that is different, or to any materially greater or lesser extent, than other companies in the energy services industry. However, our business and prospects could be adversely affected by regulatory activity that prohibits or restricts our customers’ exploration and production activities, resultsresulting in reduced demand for our services or imposesimposing environmental protection requirements that result in increased costs to us, our customers or the oil and natural gas industry in general.


The following is a summary of some of the existing laws and regulations that apply in the United States and Europe, which serves as an example of the various laws and regulations to which we are subject. While laws vary widely in each jurisdiction, each of the laws and regulations below addresses environmentalregulatory issues similar to those in most of the other jurisdictions in which we operate.
Spills and Releases. The Comprehensive Environmental Response, Compensation, and Liability Act in the U.S. (“CERCLA”), and similar state and foreign laws and regulations, impose joint and several liabilities, without regard to fault or the legality of the original act, on certain classes of persons that contributed to the release of a “hazardous substance” into the environment. In the course of our ordinary operations, we may generate waste that may fall within CERCLA’s definition of a “hazardous substance.” However, we have to-date not received any notification that we are, or may be, potentially responsible for cleanup costs under CERCLA.
Offshore Regulation and Safety.In response to the Macondo well blowout incident in April 2010, the U.S.United States Congress, the US Department of Interior, through the Bureau of Ocean Energy Management (“BOEM”) and the Bureau of Safety and Environmental Enforcement (“BSEE”), hasand the US Department of Homeland Security, through the United States Coast Guard (“USCG”), have undertaken an aggressive overhaul of the offshore oil and natural gas related regulatory process thatprocesses, which has significantly impacted oil and gas development and operational requirements in the U.S.US Gulf of Mexico. FromSuch actions by the US government has, on occasion, served as a leading indicator for similar regulatory developments or requirements by other countries where, from time to time, new rules, regulations and requirements in the United States and in other countries have been proposed and implemented by BOEM, BSEE or the United States Congress that materially limit or prohibit, and increase the cost of, offshore drilling. We are also subject to the Portsdrilling and Waterways Safety Act (“PWSA”) andrelated operations. Other similar regulations which imposeimpact certain operational requirements on offshore rigs operating in the U.S. and governsgovern liability for vessel or cargo loss, or damage to life, property, or the marine environment. See Part I, Item 1A, “Risk Factors-Risk Factors Relating to Our Business-Changes—Regulatory and Legal Risks—Changes in, compliance with, or our failure to comply with the certain laws and regulations may negatively impact our operations and could have a material adverse effect on our results of operations” and “Risk Factors—Regulatory and Legal Risks— Governmental laws and regulations may add to our costs, result in delays, or limit our drilling activity” for additional information.
Spills and Releases. The Oil Pollution Act. The U.S.US Oil Pollution Act of 1990 (“OPA”), the Comprehensive Environmental Response, Compensation, and Liability Act in the United States (“CERCLA”), and similar regulations, including but not limited to the International Convention for the Prevention of Pollution from Ships (“MARPOL”), adopted by the International Maritime Organization (“IMO”), as enforced in the United States through the domestic implementing law called the Act to Prevent Pollution from Ships, impose certain operational requirements on offshore rigs operating in the U.S.United States and govern liability for leaks, spills and blowouts involving pollutants. OPA imposes strict, joint and several liabilities on “responsible parties” for damages, including natural resource damages, resulting from oil spills into or upon navigable waters, adjoining shorelines or in the exclusive economic zone of the United States. A “responsible party” includes the owner or operator of an onshore facility and the lessee or permit holder of the area in which an offshore facility is located. CERCLA and similar state and foreign laws and regulations, impose joint and several liabilities, without regard to fault or the legality of the original act, on certain classes of persons that contributed to the release of a “hazardous substance” into the environment. In the course of our ordinary operations, we may generate waste that may fall within the scope of CERCLA's definition of a “hazardous substance.” However, we have to-date not received any notification that we are, or may be, potentially responsible for cleanup costs under CERCLA.
Regulations under OPA require owners and operators of rigs in United States waters to maintain certain levels of financial responsibility. The failure to comply with OPA’s requirements may subject a responsible party to civil, criminal, or administrative enforcement actions. We are not aware of any action or event that would subject us to liability under OPA, and we believe that compliance with OPA’s financial assurance and other operating requirements will not have a material impact on our operations or financial condition.

Waste Handling. The U.S.US Resource Conservation and Recovery Act (“RCRA”), and similar state, local and foreign laws and regulations govern the management of wastes, including the treatment, storage and disposal of hazardous wastes. RCRA imposes stringent operating requirements, and liability for failure to meet such requirements, on a person who is either a “generator” or “transporter” of hazardous waste or an “owner” or “operator” of a hazardous waste treatment, storage or disposal facility. RCRA and many state counterparts specifically exclude from the definition of hazardous waste drilling fluids, produced waters, and other wastes associated with the exploration, development, or production of crude oil and natural gas. As a result, our operations generate minimal quantities of RCRA hazardous wastes. We do not believe the current costs of managing our wastes, as they are presently classified, to be significant. However, any repeal or modification of this or similar exemption in similar state statutes, would increase the volume of hazardous waste we are required to manage and dispose of, and would cause us, as well as our competitors, to incur increased operating expenses with respect to our U.S.US operations.
Water Discharges. The U.S.US Federal Water Pollution Control Act of 1972, as amended, also known as the “Clean Water Act,” and similar state laws and regulations impose restrictions and controls on the discharge of pollutants into federal and state waters. These laws also regulate the discharge of storm water in process areas. Pursuant to these laws and regulations, we are required to obtain and maintain approvals or permits for the discharge of wastewater and storm water. In addition, the U.S. Coast GuardUSCG has promulgated requirements for ballast water management as well as supplemental ballast water requirements, which includeincludes limits and, in some cases, water treatment requirements applicable to specific discharge streams, such as deck runoff, bilge water and gray water. Further, in October 2020, the United States Environmental Protection Agency (“EPA”) published proposed national standards of performance for incidental discharges pursuant to the Vessel Incidental Discharge Act. The proposed rule would establish discharge standards for a range of vessels, including mobile offshore drilling units. We do not anticipate that compliance with these laws and regulations will cause a material impact on our operations or financial condition.
Air Emissions. The U.S.US Federal Clean Air Act and associated state laws and regulations restrict the emission of air pollutants from many sources, including oil and natural gas operations. New facilities may be required to obtain permits before operations can commence, and existing facilities may be required to obtain additional permits, and incur capital costs, in order to remain in compliance. Federal and state regulatory agencies can impose administrative, civil and criminal penalties for non-compliance with air permits or other requirements of the Clean Air Act and associated state laws and regulations. In general, we believe that compliance with the Clean Air Act and similar state laws and regulations will not have a material impact on our operations or financial condition.
Climate Change.Climate change is an environmental, social and economic challenge facing everyone today. We are committed to continuous improvement and a sustainable energy future, supported by our efforts to protect the environment throughout our operations and safely provide reliable and efficient services to allow access to resources essential for human and economic prosperity. There is increasing attention concerning the issue of climate change and the effect of greenhouse gas (“GHG”) emissions. The United States Environmental Protection Agency (“EPA”)EPA regulates the permitting of GHG emissions from stationary sources under the Clean


Air Act’s Prevention of Significant Deterioration (“PSD”) and Title V permitting programs, which require the use of “best available control technology” for GHG emissions from new and modified major stationary sources, which can sometimes include drillships.our rigs. The EPA has also adopted rules requiring the monitoring and reporting of GHG emissions from specified sources in the United States, including, among other things, certain onshore and offshore oil and natural gas production facilities, on an annual basis.
Moreover, in 2005, the Kyoto Protocol to the 1992 United Nations Framework Convention on Climate Change, which establishes a binding set of emission targets for GHGs, became binding on all countries that had ratified it. In 2015, the United Nations (“U.N.”) Climate Change Conference in Paris resulted in the creation of the Paris Agreement. In September 2016, the US deposited its instrument of acceptance of the Paris Agreement, which later entered into force on November 4, 2016. The Paris Agreement requires countries to review and “represent a progression” in their nationally determined contributions, which set emissions reduction goals, every five years beginning in 2020. IncentivesIn November 2019, the US submitted formal notification to the U.N. of its decision to withdraw from the Paris Agreement, which took effect on November 4, 2020. However, in January 2021, shortly after Joseph Biden was sworn into office as the President of the United States, a series of executive orders were issued regarding climate change, which in part led to the US again depositing an instrument of acceptance of the Paris Agreement, which thereafter re-entered into force for the US on February 19, 2021. The terms of the Paris Agreement and the executive orders are expected to result in additional regulations or changes to existing regulations, which could have a material adverse effect on our business in the US and that of our customers. In addition, incentives to conserve energy or use alternative energy sources in many of the countries where we currently operate or may operate in the future, could have a negative impact on our business if such incentives reduce the worldwide demand for oilin those countries and gas.worldwide. See Part I, Item1A, “Risk Factors—Regulatory and Legal Risks— Governmental laws and regulations may add to our costs, result in delays, or limit our drilling activity” for additional information.
Countries in the European Union (“EU”) implement the U.N.’s Kyoto Protocol on GHG emissions through the Emissions Trading System (“ETS”), though ETS will continue to require GHG reductions in the future that are not currently prescribed by the Kyoto Protocol or related agreements.. The ETS program establishes a GHG “cap and trade” system for certain industry sectors, including power generation at some offshore facilities. Total GHG from these sectors is capped, and the cap is reduced over time to achieve GHG reductions from these sectors. In September 2020, the European Commission presented a 21 percentplan to increase the EU’s GHG reduction from these sectors between 2005target to at least 55% by 2030 in accordance with the European Green Deal. In order to reach this goal, the European Commission has proposed potential revisions and 2020.expansions of the EU ETS.

In addition, the United Kingdom (“UK”) government which implementsimplemented its own ETS in January 2021 to replace the UK’s participation in the EU ETS. The UK has also introduced an auction price floor to prevent carbon prices from dropping below a set level during the initial implementation of the UK North Sea, has introduced a carbon price floor mechanism to place an incrementally increasing minimum price on carbon. Thus, theETS. The cost of compliance with the UK ETS and the EU ETS can be expected to increase over time. Additional member state climate change legislation may result in potentially material capital expenditures.
We have determined that combustion of dieselultra-low sulfur fuel (Scope 1)oil aboard all of our vessels worldwide (Scope 1) is the Company’s primary source of GHG emissions, includingwhich includes carbon dioxide, methane and nitrous oxide. The data necessary to report indirectBased upon the emissions from generation of purchased power (Scope 2) has not been previously collected. We will establishcalculation factor provided by the necessary procedures to collect and report Scope 2 data.
For the year ended December 31, 2017,original equipment manufacturer for each engine type utilized on our estimated carbon dioxide equivalent (“CO2e”) gas emissions were 918,439 tonnes as compared to 985,384 tonnesvessels, for the year ended December 31, 2016.2020, our estimated carbon dioxide equivalent (“C02e”) gas emissions were 960,593 tons as compared to 1,063,925 tons for the year ended December 31, 2019. When expressed as an intensity measure of tonnestons of CO2eC02e gas emissions per dollar of contract drilling revenues from continuing operations,day for our vessels worldwide, the intensity measure for December 31, 20172020 and 20162019 was .0008174.58 and .0004,156.85, respectively.
The increase of our C02e intensity average from 2019 to 2020 is largely attributed to fewer contracted days in 2020 for several of our vessels that have lower operating energy demands, while our larger vessels that require more energy collectively operated for more contracted days during the same period.
Noble utilizes emission coefficient factors directly from the OEM engine manufacturers carefully calculated per engine type and fuel usage to determine emissions is duegenerated from our direct operations throughout the year. While OEM provided coefficients are one method of calculation, there are other relevant industry and regulatory approved standards for calculating GHG production that lead us to a broader understanding of our GHG impact. Each of these methods of calculation vary in assumptions made during the Noble Lloyd Noble operating for the full year of 2017, as wellcalculation process. By providing these additional calculations such as the Noble Tom Madden Environmental Emissions Monitoring System (EEMS), we feel we are more prepared to compare our emissions data to those relevant industry standards and Noble Sam Croft activating and now include helicopter emissions.accurately compare to peer performance with a higher degree of transparency.
Our Scope 1 CO2eC02e gas emissions reporting has been prepared with reference to the requirements set out in the UK Companies Act 2006 Regulations 2013, the Environmental Reporting Guidelines (June 2013) issued by the Department for Environment Food & Rural Affairs, the World Resources Institute and World Business Council for Sustainable Development GHG Protocol Corporate Accounting and Reporting Standard Revised and the International Organization for Standardization (“ISO”) 14064-1, “Specification with guidance at the organizational level for quantification and reporting of greenhouse gas emissions and removals (2006).” We have used SANGEA™ Emissions Estimation Software to estimate CO2e gas of Scope 1 emissions based on diesel fuel consumption.
It is our intent to have the procedures related to GHG emissions independently assessed in the future.
Worker Safety. The U.S.US Occupational Safety and Health Act (“OSHA”) and other similar laws and regulations govern the protection of the health and safety of employees. The OSHA hazard communication standard, EPA community right-to-know regulations under Title III of CERCLA and similar state statutes require that information be maintained about hazardous materials used or produced in our operations and that this information be provided to employees, state and local governments and citizens. EU member states have also adopted regulations pursuant to EU Directive 2013/30/EU, on the safety of offshore oil and gas operations within the exclusive economic zone (which can extend up to 200 nautical miles from a coast) or the continental shelf. We believe that we are in substantial compliance with OSHA requirements and EU directive 2013/30/EU (as well as the extensive current health and safety regimes implemented in the member states in which we operate), but future developments could require the Company to incur significant costs to comply with the directive's implementation.
International Regulatory Regime.The IMO provides international regulations governing shipping and international maritimetrade. IMO regulations have been widely adopted by U.N. member countries, and in some jurisdictions in which we operate, these regulations have been expanded upon. The requirements contained in the International Management Code for the Safe Operation of Ships and for Pollution Prevention, or ISM Code, promulgated by the IMO, govern much of our drilling operations. Among other requirements, the ISM Code requires the party with operational control of a vessel to develop an extensive safety management systemthat includes, among other things, the adoption of a safety and environmental protection policy setting forth instructions and procedures for operating its vessels safely and describing procedures for responding to emergencies.
The IMO has also adopted and revised MARPOL, including Annex VI to MARPOL, which sets limits onthe main air pollutants contained in exhaust gas from ships, including sulfur dioxideoxides (“SOx”) and nitrogen oxide emissions from ship exhausts andnitrous oxides (“NOx”), prohibits deliberate emissions of ozone depleting substances. substances (“ODS”), regulates shipboard incineration and the emissions of volatile organic compounds (“VOC”) from tankers, sets a progressive reduction globally in emissions of SOx, NOx and particulate matter, introduces emission control areas (“ECAs”) to reduce emissions of those air pollutants further in designated sea areas, and effective from January 1, 2020, reduces the global sulfur limit in fuel oil from the current 3.50% to 0.50% m/m (mass by mass) sulfur content. Prior to January 1, 2020, our rigs were operating and continue to operate with low sulfur fuel oil at or below the global limits of 0.50%.
The IMO has also negotiated international conventions that


impose liability for oil pollution in international waters and the territorial waters of the signatory to such conventions such as the Ballast Water Management Convention, (the “BWM Convention”) and the International Convention for Civil Liability for Bunker Oil Pollution Damage of 2001 (the “Bunker Convention”). The BWM Convention's implementing regulations call for a phased introduction of mandatory ballast of water exchange requirements, (beginning in 2009), to be replaced in time with a requirement for
11


mandatory ballast water treatment. The Bunker Convention provides a liability, compensation and compulsory insurance system for the victims of oil pollution damage caused by spills of bunker oil. We believe that all of our drilling rigs are currently compliant in all material respects with these regulations. However, the IMO continues to review and introduce new regulations. It is impossible to predict what additional regulations, if any, may be passed by the IMO and what effect, if any, such regulation may have on our operations.
Insurance and Indemnification MattersDrilling Fleet
Our operations are subject to many hazards inherent in the drilling business, including blowouts, fires, collisions, groundings, punch-throughs, and damage or loss from adverse weather and sea conditions. These hazards could cause personal injury or loss of life, loss of revenues, pollution and other environmental damage, damage to or destruction of property and equipment and oil and natural gas producing formations, and could result in claims by employees, customers or third parties and fines and penalties.
Our drilling contracts provide for varying levels of indemnification from our customers and in most cases also require us to indemnify our customers for certain losses. Under our drilling contracts, liability with respect to personnel and property is typically assigned on a “knock-for-knock” basis, which means that we and our customers assume liability for our respective personnel and property, generally irrespective of the fault or negligence of the party indemnified. In addition, our customers may indemnify us in certain instances for damage to our down-hole equipment and, in some cases, our subsea equipment. Also, we generally obtain a mutual waiver of consequential losses in our drilling contracts.
Our customers typically assume responsibility for and indemnify us from loss or liability resulting from pollution or contamination, including third-party damages and clean-up and removal, arising from operations under the contract and originating below the surface of the water. We are generally responsible for pollution originating above the surface of the water and emanating from our drilling units. Additionally, our customers typically indemnify us for liabilities incurred as a result of a blow-out or cratering of the well and underground reservoir loss or damage. In the current market, we are under increasing pressure to accept exceptions to the above-described allocations of risk and, as a result, take on more risk. In such cases where we agree, we generally limit the exposure with a monetary cap and other restrictions.
In addition to the contractual indemnities described above, we also carry Protection and Indemnity (“P&I”) insurance, whichNoble is a comprehensive general liability insurance program covering liability resulting from offshore operations. Our P&I insurance includes coverage for liability resulting from personal injury or death of third parties and our offshore employees, third-party property damage, pollution, spill clean-up and containment and removal of wrecks or debris. Our P&I insurance program is renewed in April of each year and currently has a standard deductible of $10 million per occurrence, with maximum liability coverage of $750 million. We also carry hull and machinery insurance that protects us against physical loss or damage to our drilling rigs, subject to a deductible that is currently $25 million.
Our insurance policies and contractual rights to indemnity may not adequately cover our losses and liabilities in all cases. For additional information, please read “We may have difficulty obtaining or maintaining insurance in the future and our insurance coverage and contractual indemnity rights may not protect us against all the risks and hazards we face” included in Part I, Item 1A, “Risk Factors” of this Annual Report on Form 10-K.
The above description of our insurance program and the indemnification provisions of our drilling contracts is only a summary as of the time of preparation of this report, and is general in nature. Our insurance program and the terms of our drilling contracts may change in the future. In addition, the indemnification provisions of our drilling contracts may be subject to differing interpretations, and enforcement of those provisions may be limited by public policy and other considerations.

Item 1A. Risk Factors.
You should carefully consider the following risk factors in addition to the other information included in this Annual Report on Form 10-K. Each of these risk factors could affect our business, operating results and financial condition, as well as affect an investment in our shares.
Our business and results of operations have been materially hurt and our enterprise value has substantially declined due to current depressed market conditions which are the result of the dramatic drop in the oil price and the oversupply ofleading offshore drilling rigs.
Crude oil prices have declined from approximately $112 per barrelcontractor for Brent crude on June 30, 2014 to as low as approximately $30 per barrel in January 2016, before improving to approximately $65 per barrel on February 20, 2018. In addition, a large number of offshore drilling rigs were constructed and added to the global fleet in the last few years, and a substantial number of additional rigs, including rigs built on speculation, are available and could enter the market in 2018. Also, many in our industry extended the lives of older rigs rather than retiring these rigs. These factors have led to a significant oversupply of drilling rigs at the same time that our customers have greatly reduced their planned exploration and development spending in response to the depressed price of oil. These factors have affected market conditions and led to a material decline in the demand for our services, the dayrates we are paid by our customers and the level of utilization of our drilling rigs. These poor market conditions, in turn, have led to a material deterioration in our results of operations. We have already experienced a substantial decline in the price of our shares, which has declined from $27 on August 4, 2014 post Spin-off to $4 at February 20, 2018. While the offshore contract drilling industry is highly cyclical and has experienced periods of low demand and higher demand, there can be no assurance as to when or to what extent the current depressed market conditions, and our business, results of operations or enterprise value, will improve. Further, even if the price of oil and gas were to increase dramatically, we cannot assure you that there would be any increase in demand for our services.
Our business depends on the level of activity in the oil and gas industry. Adverse developments affectingsector. Noble owns and operates one of the industry, including a declinemost modern, versatile and technically advanced fleets of mobile offshore drilling units in the priceoffshore drilling industry. Noble provides, through its subsidiaries, contract drilling services with a fleet of oil19 offshore drilling units, consisting of seven floaters and 12 jackups at the date of this report, focused largely on ultra-deepwater and high-specification drilling opportunities in both established and emerging regions worldwide. Each type of drilling rig is described further below. Several factors determine the type of unit most suitable for a particular job, the most significant of which include the water depth and the environment of the intended drilling location, whether the drilling is being done over a platform or gas, reduced demand forother structure, and the intended well depth. At December 31, 2020, our fleet was located in Far East Asia, the Middle East, the North Sea, Oceania, South America and the US Gulf of Mexico.
Floaters
Our floating fleet consists of the following:
    A drillship is a type of floating drilling unit that is based on the ship-based hull of the vessel and equipped with modern drilling equipment that gives it the capability of easily transitioning from various worldwide locations and carrying high capacities of equipment while being able to drill ultra-deepwater oil and gas productswells in up to 12,000 feet of water. Drillships can stay directly over the drilling location without anchors in open seas using a dynamic positioning system (“DPS”), which coordinates position references from satellite signals and increased regulation of drilling and production, could have a material adverse effect on our business, financial condition and results of operations.
Demand for drilling services depends on a variety of economic and political factors andacoustic seabed transponders with the level of activity in offshoredrillship's six to eight thrusters to keep the ship directly over the well that is being drilled. Drillships are selected to drill oil and gas exploration and development and production markets worldwide. As noted above,wells for programs that require a high level of simultaneous operations, where drilling loads are expected to be high, or where there are occurrences of high ocean currents, where the pricedrillship's hull shape is the most efficient. Noble's fleet consists of oil and gas, and market expectationssix drillships capable of potential changeswater depths from 10,000 feet to 12,000 feet.
    Semisubmersible drilling units are designed as a floating drilling platform incorporating one or several pontoon hulls, which are submerged in the price, significantly affectwater to lower the center of gravity and make this leveltype of activity,drilling unit exceptionally stable in the open sea. Semisubmersible drilling units are generally categorized in terms of the water depth in which they are capable of operating, from the mid-water range of 300 feet to 4,000 feet, the deepwater range of 4,000 feet to 7,500 feet, to the ultra-deepwater range of 7,500 feet to 12,000 feet as well as dayratesby their generation, or date of construction. This type of drilling unit typically exhibits excellent stability characteristics, providing a stable platform for drilling in even rough seas. Semisubmersible drilling units hold their position over the drilling location using either an anchored mooring system or a DPS and may be self-propelled. Noble’s fleet consists of one moored ultra-deepwater semisubmersible drilling unit.

Jackups
Noble’s fleet of modern, high-specification jackup drilling units gives us the flexibility to provide drilling solutions to our customers who have drilling requirements in the shallower waters of the continental shelf, in depths ranging from less than 100 feet to as deep as 500 feet of water with drilling hookloads up to 2,500,000. Jackup rigs can be used in open water exploration locations, as well as over fixed, bottom-supported platforms. A jackup drilling unit is a towed mobile vessel consisting of a floating hull equipped with three or four legs, which weare lowered to the seabed at the drilling location. The hull is then elevated out of the water by the jacking system using the legs to support weight of the hull and drilling equipment against the seabed. Once the hull is elevated to the desired level, or jacked up, the drilling package can charge customersbe extended out over an existing production platform or the open water location and drilling can commence. Noble’s fleet of 12 jackups varies from two units capable of drilling in up to 375 feet of water to premium and high-specification units capable of drilling in up to 500 feet of water.
The following table presents certain information concerning our offshore fleet at March 10, 2021. We own and operate all of the units included in the table.

The current downturn has had a material adverse effect on demand for our services since 2015 and is expected to continue to have a material adverse effect on our business and results of operations.
The contract drilling industry is a highly competitive and cyclical business with intense price competition. If we are unable to compete successfully, our profitability may be materially reduced.Market
The offshore contract drilling industry is a highly competitive and cyclical business characterizedbusiness. Demand for offshore drilling services is driven by high capitalthe offshore exploration and operating costsdevelopment programs of oil and evolving capabilitygas operators, which in turn are influenced by many factors, including, but not limited to, the price and price stability of newer rigs. Drilling contracts are traditionally awarded on a competitive bid basis. Priceoil and gas, the availability and relative cost of offshore oil and gas resources within the oil and gas portfolio of each operator, general global economic conditions, energy demand, the operator’s strategy toward renewable energy sources, environmental considerations and national oil and gas policy.
In the provision of offshore contract drilling services, competition rigis largely governed by price but involves numerous other factors as well. Rig availability, location, and rig suitability and technical specifications are the primary factors in determining which rig is qualified for a job, and additional factors are considered when determining which contractor is awarded a job, although other factors are important, including experience of the workforce, efficiency, safety performance record, condition of equipment, operating integrity, reputation, industry standing and client relations. Our future success and profitability will partly depend upon our ability to keep pace with our customers’ demands with respect to these factors. If current competitors, or new market entrants, implement new technical capabilities, services or standards that are more attractive to our customers or price their product offerings more competitively, it could have a material adverse effect on our business, financial condition and results of operations.
In addition to intense competition, our industry has historically been cyclical. The contract drilling industry is currently in a period characterized by low demand for drilling services and excess rig supply. Periodshaving one of low demand or excess rig supply intensify the competitionnewest fleets in the industry among our peer companies, we strive to keep our assets well-maintained and have resulted in,technologically competitive.
We maintain a global operational presence and are expected to continue to resultcompete in many of the major offshore oil and gas basins worldwide. All our drilling rigs being idle or earning substantially lower dayratesare mobile, and we may mobilize our drilling rigs among regions for long periodsa variety of time.reasons, including to respond to customer requirements. We cannot provide you with any assurances as to when such period will end, or when there will be higher demand for contract drilling services or a reductioncompete in both the numberjackup and floating rig market segments, each of drilling rigs.
The over-supply of rigs is contributing to a reduction in dayrateswhich may have different supply and demand for our rigs, which reduction may continue for somedynamics at a given period in time and, therefore, is expected to further adversely impact our revenues and profitability.or in different regions.
Prior to the current downturn, we experienced an extended period of high utilization and high dayrates, and industry participants materially increased the supply of drilling rigs by building new drilling rigs, including some that have not yet entered service. This increase in supply, combined with the decrease in demand for drilling rigs resulting from the substantial decline in the price of oil that began inSince late 2014, the offshore drilling industry has resulted inexperienced a severe and prolonged downturn driven by a combination of an oversupply of drilling rigs, which has contributed toweak and volatile crude oil prices exacerbated in early 2020 by production level disagreements by OPEC+, reductions in global offshore exploration and development activities, and the decline in utilization and dayrates.impacts of COVID-19.
We are currently experiencing competition from newbuild rigs thatThe global mitigation efforts associated with preventing the spread of COVID-19 have either already entered the market or are available to enter the market. The entry of these rigs into the market has resulted in lower dayrates for both newbuilds and existing rigs rolling off their current contracts. Lower utilization and dayrates have adversely affected our revenues and profitability and may continue to do so for some time in the future. In addition, our competitors may relocate rigs to geographic markets in which we operate, which could exacerbate excess rig supply and result in


lower dayrates and utilization in those markets. To the extent that the drilling rigs currently under construction or on order do not have contracts upon their completion, there may be increased price competition as such vessels become operational, which could leadsignificantly slowed global economic activity, leading to a further reductionprecipitous drop in dayratesoil demand in 2020. As the year progressed, some countries began to ease lock-down restrictions, resulting in an increase in oil demand; however, current demand and near-term demand forecasts still lag pre-COVID-19 demand levels. As the demand imbalance played out during the year, crude price volatility lessened as OPEC+ agreed to production level cuts through early 2021. In early 2021, Brent crude averaged $55-$60 per barrel, up from an average of approximately $40 per barrel in utilization, and we may be required to idle additional drilling rigs. As2020. Despite the current price recovery, uncertainty remains around the current level of oil prices as a result our business, financial condition and results of operations would be materially adversely affected.
We may record impairment charges on property and equipment, including rigs and related capital spares.
We evaluate the impairment of property and equipment, which include rigs and related capital spares, whenever events or changes in circumstances (including a decision to cold stack, retire or sell rigs) indicate that the carrying amount of an asset may not be recoverable. An impairment loss on our property and equipment may exist when the estimated undiscounted cash flows expected to result from the use of the asseton-going effects of COVID-19 and its eventual disposition are less than its carrying amount. Any impairment loss recognized represents the excessearly stage of global vaccine efforts, as well as the uncertainty surrounding the longevity of the asset’s carrying value over the estimated fair value. As part of this analysis, we make assumptions and estimates regarding future market conditions. To the extent actual results do not meet our estimated assumptions, forOPEC+ production agreements. Finally, a given rig or piece of equipment,we may take an impairment loss in the future. In addition, we may also take an impairment loss on capital spares and other capital equipment when we deem the value of those items has declined due to factors like obsolescence, deterioration or damage. For example, based upon our impairment analysis asgrowing number of the years ended December 31, 2017 and 2016, we decided that we would no longer market certain rigs. In connection with these decisions, we recorded impairment charges of $121.6 million and $285.0 million, respectively, on these rigs and certain capital spares during those periods. There can be no assurance that we will not have to take additional impairment charges in the future if current depressed market conditions persist.
We may not be able to renew or replace expiring contracts, and our customers may terminate or seek to renegotiate or repudiate our drilling contracts or may have financial difficulties which prevents them from meeting their obligations under our drilling contracts.
We had a number of customer contracts that expired in 2016 and 2017 and will expire in 2018. Generally speaking we were not able to renew or replace contracts that expired in 2016 and 2017 on as favorable terms as our previous contracts, if at all, and our ability to renew contracts that expire in 2018 or obtain new contracts and the terms of any such contracts will depend on market conditions and our customers' expectations and assumptions of futuremajor oil prices and other factors. During 2016 and 2017, a number of oil and gas companies, including some of our customers, publicly announced significant reductionshave signaled increased commitments toward the transition to renewable energy sources. As international majors commit to these renewable energy sources, capital investments could be diverted from longer-term fossil fuel projects, creating even more competition among premium offshore drilling assets.
We believe the convergence of events in their planned exploration2020 and development spending affectingearly 2021 have lengthened an already challenging and slow recovery in our industry. Despite these challenges and demand projections, we believe that oil and gas demand will rebalance and oil and gas will remain an important portion of the world’s energy mix. We expect that the return of stable oil demand and prices coupled with the continued attrition of rigs in the global offshore fleet will bring improved market conditions for our services. Our young and some of our customers may continuetechnologically advanced fleet is well positioned to do so in 2018. These reductions in spending by our customers could further reduce the demand forcompete as market dynamics improve.
Significant Customers
Offshore contract drilling services and as a result, our business, financial condition and results of operations would be materially adversely affected.
Our customers may generally terminate our term drilling contracts if a drilling rig is destroyed or lost or if we have to suspend drilling operations for a specified period of time as a result of a breakdown of major equipment or, in some cases, due to other events beyond the control of either party. In the case of nonperformance and under certain other conditions, our drilling contracts generally allow our customers to terminate without any payment to us. The terms of some of our drilling contracts permit the customer to terminate the contract after a specified notice period by tendering contractually specified termination amounts and, in some cases, without any payment. These termination payments, if any, may not fully compensate us for the loss of a contract. The early termination of a contract may result in a rig being idle for an extended period of time and a reduction in our contract backlog and associated revenue, which could have a material adverse effect on our business, financial condition and results of operations.
In addition, during periods of depressed market conditions, such as the one we are currently experiencing, we are subject to an increased risk of our customers seeking to renegotiate or repudiate their contracts. The ability of our customers to perform their obligations under drilling contracts with us may also be adversely affected by the financial condition of the customer, restricted credit markets, economic downturns and industry downturns. We may elect to renegotiate the rates we receive under our drilling contracts downward if we determine that to be a reasonable business solution. If our customers cancel or are unable to perform their obligations under their drilling contracts, including their payment obligations, and we are unable to secure new contracts on a timely basis on substantially similar terms or if we elect to renegotiate our drilling contracts and accept terms that are less favorable to us, it could have a material adverse effect on our business, financial condition and results of operations.
Our current backlog of contract drilling revenue may not be ultimately realized.
Generally, contract backlog only includes future revenues under firm commitments; however, from time to time, we may report anticipated commitments under letters of intent or award for which definitive agreements have not yet been, but are expected to be, executed. We may not be able to perform under these contracts as a result of operational or other breaches or due to events beyond our control, and we may not be able to ultimately execute a definitive agreement in cases where one does not currently exist. Moreover, we can provide no assurance that our customers will be able to or willing to fulfill their contractual commitments to us or that they will not seek to renegotiate or repudiate their contracts, especially during the current industry downturn. In estimating backlog, we make certain assumptions about applicable dayrates for our longer-term contracts with dayrate adjustment mechanisms (like certain of our contracts with Shell). While we believe these assumptions are appropriate, we cannot assure you that actual results will mirror these assumptions. Our inability to perform under our contractual obligations or to execute definitive


agreements, our customers’ inability or unwillingness to fulfill their contractual commitments to us, including as a result of contract repudiations or our decision to accept less favorable terms on our drilling contracts, or the failure of actual results to reflect the assumptions we use to estimate backlog for certain contracts, may have a material adverse effect on our business, financial condition and results of operations.
We are substantially dependent on several of our customers, including Shell, Statoil and Saudi Aramco, and the loss of any of these customers would have a material adverse effect on our financial condition and results of operations.
Any concentration of customers increases the risks associated with any possible termination or nonperformance of drilling contracts, failure to renew contracts or award new contracts or reduction of their drilling programs. Shell, Statoil and Saudi Aramco accounted for approximately 4594 percent, 1395 percent and 1196 percent of our operating revenues for the years ended December 31, 2020, 2019 and 2018, respectively. During the three years ended December 31, 2020, we principally conducted our contract drilling operations in Canada, Far East Asia, the Middle East, the North Sea, Oceania, the Black Sea, Africa, South America and the US Gulf of Mexico. Revenues from Exxon Mobil Corporation (“ExxonMobil”), Royal Dutch Shell plc (“Shell”), Equinor ASA (“Equinor”) and Saudi Arabian Oil Company (“Saudi Aramco”) accounted for approximately 26.6 percent, 21.7 percent, 14.3 percent and 13.8 percent, respectively, of our consolidated operating revenues and approximately 58 percent, 14 percent and 19 percent, respectively, of our backlog for the year ended December 31, 20172020. Revenues from Shell, ExxonMobil, Equinor and Saudi Aramco accounted for approximately 36.5 percent, 13.7 percent, 13.1 percent and 11.9 percent, respectively, of our consolidated operating revenues, which includes the Noble Bully II contract buyout, for the year ended December 31, 2019. Excluding the Noble Bully II contract buyout, revenues from Shell, ExxonMobil, Equinor and Saudi Aramco accounted for approximately 27.1 percent, 15.7 percent, 15.1 percent and 13.6 percent, respectively, of our consolidated operating revenues for the year ended December 31, 2019. Revenues from Shell, Equinor and Saudi Aramco accounted for approximately 38.8 percent, 15.5 percent and 14.5 percent, respectively, of our consolidated operating revenues for the year ended December 31, 2018. No other customer accounted for more than 10 percent of our consolidated operating revenues in 2020, 2019 or 2018.

Human Capital
At December 31, 2020, we had approximately 1,500 employees, excluding approximately 800 persons we engaged through labor contractors or agencies. Approximately 88 percent of our workforce is located offshore. We are not a party to any material collective bargaining agreements, and we consider our employee relations to be satisfactory.
We are fully committed to operating our business with honesty and integrity. Our reputation depends on our directors, officers, employees, and others working on our behalf assuming a personal responsibility for our business conduct. Our compliance program is focused on ensuring adherence with the highest ethical standards and applicable laws and setting the tone for an ethical work environment. Noble’s commitment to a strong compliance culture is fundamental to who we are as a leading offshore drilling contractor. Noble’s Code of Business Conduct and Ethics provides the foundation for our culture and underscores our commitment to our core values of safety, environmental stewardship, honesty and integrity, respect and performance. It also includes our responsibility and commitment to follow all applicable laws as well as our own internal policies, and requires any supplier or third party who works with Noble to comply with similar fundamental principles.
Operating our business in a socially responsible way is integral to who we are. Internally, our employee-focused programs such as recruitment and promotion opportunities, safety and environmental stewardship, and training and continuing education are key to our commitment to the personal and professional growth of our workforce. Externally, our dedication is evidenced by our affiliations and how we contribute to and invest in the communities where we operate.
Recruitment and Promotions. This concentrationWe value a healthy culture of ingenuity and adaptability where everyone has an equal opportunity to thrive. We recognize that an inclusive and diverse workforce is key to the advancement and retention of the best qualified people leading to strong innovation and our continued success. We are committed to a policy of recruitment and promotion based upon job qualifications, performance and merit without discrimination.
Safety and Environmental Stewardship. Noble is committed to delivering excellent health, safety and environmental (“HSE”) performance as part of our business strategy in order to add further value for employees, customers, increasesand shareholders. Safety and environmental stewardship are the cornerstone of who we are, what we stand for and what we do every day to deliver a high-quality operation. All personnel, regardless of job or position onboard our vessels or at any Noble facility, has the authorization and obligation to immediately stop any unsafe act, practice or job that that poses any risk or danger to people or the environment. Noble’s pursuit of exceptional HSE performance begins with our strong corporate culture and by starting SAFE every day: one tour, one task and one person at a time. SAFE is an acronym for the phrase: follow Standards, be Accountable, stay Focused, achieve Excellence. Daily, the crew onboard each rig work together to achieve specific safety and environmental objectives and if all objectives are met, then the day is counted as a SAFE Day. Under our SAFE Day program, in 2020, our rigs achieved the SAFE objectives 98.6% of available days, which is an increase over 2019 performance, and our total recordable incident rate for 2020 decreased 38% from the prior year.
Training and Continuing Education. We place considerable value on the training and development of our employees and maintain a practice of keeping them informed on matters affecting them, as well as on the performance of the Company. Accordingly, we conduct formal and informal meetings with employees, maintain a Company intranet website with matters of interest, issue periodic publications of Company activities and other matters of interest, and offer a variety of in-house training, including through NobleAdvances, our state-of-the-art training facility in Sugar Land, Texas. When travel became a challenge, we developed and enhanced virtual and worksite training courses, some of which are facilitated through our rig-based leadership and are accredited through the International Association of Drilling Contractors.
In consideration of the negative impact of COVID-19 on our employees, customers, suppliers and the communities in which we operate, as well as associated human rights concerns that may exist in the areas in which we operate, we have taken, and will continue to take, incremental measures to monitor, identify and manage risks associated with any possible termination or nonperformancethe COVID-19 pandemic. Throughout the pandemic, we have continued operations in support of contracts,essential infrastructure in addition to our exposure to credit risk. If any of these customers were to terminate or fail to perform their obligations under their contracts and we were notthe energy industry while carefully ensuring worker safety. We have been able to find other customers for the affected drilling units promptly, our financial condition and results of operations could be materially adversely affected.

Paragon Offshore has formed and funded a litigation trust as part of its bankruptcy proceedings and the litigation trust has filed claims against us and certainmaintain operation of our officers and directors. In addition, Paragon Offshore has rejected in the bankruptcy proceedings certain separation agreements entered into with us, andrigs by implementing several mitigations, such as a result, we will be responsible for those liabilities for which we would have otherwise sought indemnification under the separation agreements.

In August 2014, we completed the Spin-off of a majority of our standard specification offshore drilling business through a pro rata distribution of all of the ordinary shares of our wholly-owned subsidiary, Paragon Offshore,extending crew schedules to the holders of our ordinary shares. In April 2017, Paragon Offshore filed a bankruptcy plan (the “Plan”). The Plan, which was modified in May 2017, provided for the creation of a litigation trustoffset travel delays due to which Paragon Offshore transferred its claims against us, including claims of alleged fraudulent conveyance in connection with the Spin-off and the funding of the trust by Paragon Offshore with $10.0 million. The litigation trust is entitled to pursue those claims against us. In June 2017, the revised Plan was approved by the bankruptcy court and Paragon Offshore emerged from bankruptcy on July 18, 2017.

On December 15, 2017, the litigation trust filed claims relating to the Spin-off against us and certain of our current and former officers and directors in the Delaware bankruptcy court that heard Paragon Offshore’s bankruptcy. The complaint alleges claims of alleged actual and constructive fraudulent conveyance, unjust enrichment and recharacterization of intercompany notes as equity claims against Noble and claims of breach of fiduciary duty and aiding and abetting breach of fiduciary duty against the officer and director defendants. If any of the litigation trust’s claims are successful,limitations or if we elect to settle any claims, any damages or other amounts we would be required to or agree to pay could have a material adverse effect on our business, financial condition and results of operations. The litigation is in the very early stages, no schedule has been established, and we are not able to predict when, or if, the matters will go to trial or otherwise be concluded. We may be required to establish reserves on our financial statementsrestrictions, implementing quarantine measures in advance of persons boarding our rigs to prevent the conclusionspread of COVID-19 on board and enhancing crew health monitoring and response measures to prevent an outbreak on board any of our vessels. We have also continued the litigation. Such reservesoperation of our shore-side offices by implementing social distancing programs and implementing staggered rotational schedules for facility employees to reduce the number of persons on site. In addition, we have increased internal contingency planning, protective measures and employee communications and reinforced our employee wellness programs with all offshore and shore-side employees to offset the potential impact on employees both personally and professionally.

Governmental Regulations and Environmental Matters
Political developments and numerous governmental regulations, which may be substantial and could have a material adverse effect onrelate directly or indirectly to the contract drilling industry, affect many aspects of our financial condition as presented in such financial statements.

We entered into certain separation agreements with Paragon Offshore at the time of the Spin-off (including the master separation agreement, tax sharing agreement, transition services agreement and transition services agreement relating to our operations offshore Brazil) under which we agreed to indemnify Paragon Offshore for certain liabilities, and Paragon Offshore agreed to indemnify us for certain liabilities. As part of the Plan, Paragon Offshore rejected all of these contracts. Accordingly, we are no longer entitled to seek indemnity from Paragon Offshore under such agreements, and we would be responsible for those liabilities for which we would have otherwise sought indemnification. Such liabilities could have a material adverse effect on our business, financial condition and results of operations.
Our business involves numerous operating hazards.
Ourcontract drilling operations are subject to many hazards inherentvarious laws and regulations in countries in which we operate, including laws and regulations relating to the equipping, supplying and operation of drilling business, including:
well blowouts;
fires;
collisions or groundings of offshore equipmentunits, environmental protection and helicopter accidents;
punch-throughs;
mechanical or technological failures;
failure of our employees or third-party contractors to comply with our internal environmental,related recordkeeping, health and safety guidelines;
pipe or cement failuresof personnel, safety management systems, the reduction of atmospheric emissions that contribute to a cumulative effect on the overall air quality and casing collapses, which could release oil, gas or drilling fluids;
geological formations with abnormal pressures;
loop currents or eddies;


failure of critical equipment;
toxic gas emanating from the well;
spillage handlingenvironment (commonly referred to as greenhouse gases), currency conversions and disposing of materials; and
adverse weather conditions, including hurricanes, typhoons, tsunamis, winter storms and rough seas.
These hazards could cause personal injury or loss of life, suspend drilling operations, result in regulatory investigation or penalties, seriously damage or destroy property and equipment, result in claims by employees, customers or third parties, cause environmental damage and cause substantial damage torepatriation, oil and gas producing formations or facilities. Operations also may be suspended becauseexploration and development, taxation of machinery breakdowns, abnormal drilling conditions,capital equipment, taxation of offshore earnings and failureearnings of subcontractors to perform or supply goods or services orexpatriate personnel, shortages. The occurrenceemployee benefits and use of anylocal employees, content and suppliers by foreign contractors. A number of countries actively regulate and control the ownership of concessions and companies holding concessions, the exportation of oil and gas and other aspects of the hazards we face could have a material adverse effect on our business, financial conditionoil and results of operations.
We may experience downgradesgas industries in our credit ratings, which could increase our borrowing costs and potentially reduce our access to additional liquidity.

As a result of the decline in our credit ratings below investment grade in 2016, access to the commercial paper market became closed to us and we terminated our commercial paper program. So long as such access is closed, any future borrowings would have to be made under our Credit Facilities (as defined herein). Each of our Credit Facilities has a provision which changes the applicable interest rate based upon our credit ratings, and these reduced credit ratings have increased our potential interest expense for borrowings under our 2015 Credit Facility (as defined herein).
During 2016 and 2017, we experienced debt rating downgrades by Moody’s Investors Service and S&P Global Ratings, which reduced our debt ratings significantly below investment grade. As a result of these downgrades, we experienced interest rate increases during 2016 and 2017 on our Senior Notes due 2018 (the “2018 Notes”), our Senior Notes due 2025 (the “2025 Notes”) and our Senior Notes due 2045 (the “2045 Notes”), all of which are subject to provisions that vary the applicable interest rates based on our debt rating. On October 18, 2017, S&P Global Ratings further reduced our debt rating, which will increase the interest rates on the 2025 Notes and the 2045 Notes to 7.95% and 8.95%, respectively, beginning in April 2018. Once the new interest rates take effect in April 2018, these senior notes will have reached the contractually-defined maximum interest rate set for each rating agency and no further interest rate increase will occur.
Our other outstanding senior notes, including the Senior Notes due 2024 (the “2024 Notes”) issued in December 2016, and the Senior Notes due 2026 (the “2026 Notes”) issued in January 2018, do not contain provisions varying applicable interest rates based upon our credit ratings.
We are exposed to risks relating to operations in international locations.
We operate in various regions throughout the world that may expose us to political and other uncertainties, including risks of:
seizure, nationalization or expropriation of property or equipment;
monetary policies, government credit rating downgrades and potential defaults, and foreign currency fluctuations and devaluations;
limitations on the ability to repatriate income or capital;
complications associated with repairing and replacing equipment in remote locations;
repudiation, nullification, modification or renegotiation of contracts;
limitations on insurance coverage, such as war risk coverage, in certain areas;
import-export quotas, wage and price controls, imposition of trade barriers and other forms of government regulation and economic conditions that are beyond our control;
delays in implementing private commercial arrangements as a result of government oversight;
financial or operational difficulties in complying with foreign bureaucratic actions;
changing taxation rules or policies;
other forms of government regulation and economic conditions that are beyond our control and that create operational uncertainty;
governmental corruption;
piracy; and
terrorist acts, war, revolution and civil disturbances.
Further, we operate in certain less-developed countries with legal systems that are not as mature or predictable as those in more developed countries, which can lead to greater uncertainty in legal matters and proceedings. Examples of challenges of operating in these countries include:
procedural requirements for temporary import permits, which may be difficult to obtain;
the effect of certain temporary import permit regimes, where the duration of the permit does not coincide with the general term of the drilling contract; and
ongoing claims in Brazil related to withholding taxes payable on our service contracts.


Our ability to do business in a number of jurisdictions is subject to maintaining required licenses and permits and complying with applicable laws and regulations. Changes in, compliance with, or our failure to comply with the laws and regulations of the countries where we operate may negatively impact our operations in those countries and could have a material adverse effect on our results of operations.
their countries. In addition, OPECgovernment actions, including initiatives as well as other governmental actions,by OPEC, may continue to causecontribute to oil price volatility. In some areas of the world, this governmentalgovernment activity has adversely affected the amount of exploration and development work done by major oil and gas companies which may continue. In addition, some governments favor or effectively require the awarding ofand influenced their need for offshore drilling contractsservices, and likely will continue to local contractors, require use of a local agent, require partial local ownership or require foreign contractors to employ citizens of, or purchase supplies from, a particular jurisdiction. These practices may adversely affect our ability to compete and our results of operations.do so.
Operating and maintenance costs of our rigs may be significant and may not correspond to revenue earned.
Our operating expenses and maintenance costs depend on a variety of factors including: crew costs, costs of provisions, equipment, insurance, maintenance and repairs, and shipyard costs, many of which are beyond our control. Our total operating costs are generally related to the number of drilling rigs in operation and the cost level in each country or region where such drilling rigs are located. Equipment maintenance costs fluctuate depending upon the type of activity that the drilling rig is performing and the age and condition of the equipment. Operating and maintenance costs will not necessarily fluctuate in proportion to changes in operating revenues. While operating revenues may fluctuate as a function of changes in dayrate, costs for operating a rig may not be proportional to the dayrate received and may vary based on a variety of factors, including the scope and length of required rig preparations and the duration of the contractual period over which such expenditures are amortized. Any investments in our rigs may not result in an increased dayrate for or income from such rigs. A disproportionate amount of operating and maintenance costs in comparison to dayrates could have a material adverse effect on our business, financial condition and results of operations.
Drilling contracts with national oil companies may expose us to greater risks than we normally assume in drilling contracts with non-governmental clients.
Contracts with national oil companies 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 and other claims for damages (including consequential damages) and personal injury relatedThe regulations applicable to our operations include provisions that regulate the discharge of materials into the environment or the risk that the contract may be terminated by our client without cause on short-term notice, contractually or by governmental action,require remediation of contamination under certain conditions that may not provide us an early termination payment, collection riskscircumstances. Many of the countries in whose waters we operate from time to time regulate the discharge of oil and political risks. In addition, our abilityother contaminants in connection with drilling and marine operations. Failure to resolve disputes or enforce contractual provisions may be negatively impactedcomply with these contracts. While we believe that the financial, commercial and risk allocation terms of these contracts and our operating safeguards mitigate these risks, 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 rigs contracted to national oil companies with commensurate additional contractual risks.
Governmental laws and regulations, may addor failure to our costs,obtain or comply with permits, may result in delays, or limit our drilling activity.
Our business is affected by public policythe assessment of administrative, civil and lawscriminal penalties, imposition of remedial requirements and regulations relatingthe imposition of injunctions to the energy industry in the geographic areas where we operate.
The drilling industry is dependent on demand for services fromforce future compliance. Although these requirements impact the oil and gas and energy services industries, generally they do not appear to affect us in any material respect that is different, or to any materially greater or lesser extent, than other companies in the energy services industry. However, our business and prospects could be adversely affected by regulatory activity that prohibits or restricts our customers’ exploration and production activities, resulting in reduced demand for our services or imposing environmental protection requirements that result in increased costs to us, our customers or the oil and natural gas industry and accordingly, we are directly affected byin general.
The following is a summary of some of the adoption ofexisting laws and regulations that for economic, environmental or other policy reasons curtail exploration and development drilling for oil and gas. We may be required to make significant capital expenditures to comply with governmental laws and regulations. Governments in some foreign countries are increasingly active in regulating and controlling the ownership of concessions, the exploration for oil and gas, and other aspects of the oil and gas industries. There is increasing attentionapply in the United States and worldwide concerningEurope, which serves as an example of the issuevarious laws and regulations to which we are subject. While laws vary widely in each jurisdiction, each of climate changethe laws and regulations below addresses regulatory issues similar to those in most of the other jurisdictions in which we operate.
Offshore Regulation and Safety.In response to the Macondo well blowout incident in April 2010, the United States Congress, the US Department of Interior, through the Bureau of Ocean Energy Management (“BOEM”) and the effectBureau of greenhouse gases, or GHGs. This increased attention may result in new environmental laws or regulations that may unfavorably impact us, our suppliersSafety and our customers.
The modificationEnvironmental Enforcement (“BSEE”), and the US Department of existing laws or regulations orHomeland Security, through the adoptionUnited States Coast Guard (“USCG”), have undertaken an aggressive overhaul of new laws or regulations that result in the curtailment of exploratory or developmental drilling foroffshore oil and natural gas related regulatory processes, which has significantly impacted oil and gas coulddevelopment and operational requirements in the US Gulf of Mexico. Such actions by the US government has, on occasion, served as a leading indicator for similar regulatory developments or requirements by other countries where, from time to time, new rules, regulations and requirements in the United States and in other countries have been proposed and implemented that materially limit or prohibit, and adversely affect our operations by limiting drilling opportunities increasing ourincrease the cost of, doing business, discouraging our customers fromoffshore drilling and related operations. Other similar regulations impact certain operational requirements on rigs and govern liability for hydrocarbons, disrupting revenue through permittingvessel or similar delays,cargo loss, or subjecting usdamage to liability.
As disclosed inlife, property, or the marine environment. See Part II,I, Item 8, “Financial Statements1A, “Risk Factors —Regulatory and Supplementary Data, Note 14— Commitments and Contingencies,” in November 2012, the U.S. Coast Guard in Alaska conducted an inspection and investigation of the Noble Discoverer and the Kulluk, a rig we were providing contract labor services for, and referred the matters to the DOJ for further investigation. In December 2014, a subsidiary reached a settlement with the DOJ regarding its investigation of the Noble Discoverer and the Kulluk. Under the terms of the plea agreement, the subsidiary pled guilty to violations relating to maintaining proper oil record books for the Noble Discoverer and Kulluk, maintaining proper ballast records for the Noble Discoverer and notification of hazardous conditions with respect to the Noble Discoverer. The subsidiary paid $8.2 million in fines and $4 million in community service payments and implemented a comprehensive environmental compliance plan. Under the plea agreement, we were also placed on probation for four years, with the right to petition the court for early dismissal of probation after three years. We were granted our motion


to terminate the plea agreement effective March 1, 2018. If, during the remaining term of probation, the subsidiary fails to adhere to the terms of the plea agreement, the DOJ may withdraw from the plea agreement and would be free to prosecute the subsidiary on all charges arising out of its investigation, including any charges dismissed pursuant to the terms of the plea agreement, as well as potentially other charges.
Any violation of anti-bribery or anti-corruption laws, including the Foreign Corrupt Practices Act, the United Kingdom Bribery Act, or similar laws and regulations could result in significant expenses, divert management attention, and otherwise have a negative impact on us.
We operate in countries known to have a reputation for corruption. We are subject to the risk that we, our affiliated entities or their respective officers, directors, employees and agents may take action determined to be in violation of such anti-corruption laws, including the U.S. Foreign Corrupt Practices Act of 1977 (the FCPA), the United Kingdom Bribery Act 2010 (the U.K. Bribery Act) and similar laws in other countries. Any violation of the FCPA, U.K. Bribery Act or other applicable anti-corruption laws could result in substantial fines, sanctions, civil and/or criminal penalties and curtailment of operations in certain jurisdictions and might adversely affect our business, results of operations or financial condition. In addition, actual or alleged violations could damage our reputation and ability to do business. Further, detecting, investigating and resolving actual or alleged violations is expensive and can consume significant time and attention of our senior management.
Legal Risks—Changes in, compliance with, or our failure to comply with the certain laws and regulations may negatively impact our operations and could have a material adverse effect on our results of operations.
Our operations are subject to variousoperations” and “Risk Factors—Regulatory and Legal Risks— Governmental laws and regulations may add to our costs, result in countriesdelays, or limit our drilling activity” for additional information.
Spills and Releases. The US Oil Pollution Act of 1990 (“OPA”), the Comprehensive Environmental Response, Compensation, and Liability Act in the United States (“CERCLA”), and similar regulations, including but not limited to the International Convention for the Prevention of Pollution from Ships (“MARPOL”), adopted by the International Maritime Organization (“IMO”), as enforced in the United States through the domestic implementing law called the Act to Prevent Pollution from Ships, impose certain operational requirements on offshore rigs operating in the United States and govern liability for leaks, spills and blowouts involving pollutants. OPA imposes strict, joint and several liabilities on “responsible parties” for damages, including natural resource damages, resulting from oil spills into or upon navigable waters, adjoining shorelines or in the exclusive economic zone of the United States. A “responsible party” includes the owner or operator of an onshore facility and the lessee or permit holder of the area in which we operate, includingan offshore facility is located. CERCLA and similar state and foreign laws and regulations, relating to:
impose joint and several liabilities, without regard to fault or the importing, exporting, equipping and operation of drilling rigs;
currency exchange controls;
oil and gas exploration and development;
taxation of offshore earnings and earnings of expatriate personnel; and
use and compensation of local employees and suppliers by foreign contractors.
Public and regulatory scrutinylegality of the energy industry has resultedoriginal act, on certain classes of persons that contributed to the release of a “hazardous substance” into the environment. In the course of our ordinary operations, we may generate waste that may fall within the scope of CERCLA's definition of a “hazardous substance.” However, we have to-date not received any notification that we are, or may be, potentially responsible for cleanup costs under CERCLA.
Regulations under OPA require owners and operators of rigs in increased regulations being either proposedUnited States waters to maintain certain levels of financial responsibility. The failure to comply with OPA’s requirements may subject a responsible party to civil, criminal, or implemented. In addition, existing regulations might be revisedadministrative enforcement actions. We are not aware of any action or reinterpreted, new laws, regulationsevent that would subject us to liability under OPA, and permittingwe believe that compliance with OPA’s financial assurance and other operating requirements might be adoptedwill not have a material impact on our operations or become applicable to us, our rigs, our customers, our vendors or our service providers,financial condition.

Waste Handling. The US Resource Conservation and future changes inRecovery Act (“RCRA”), and similar state, local and foreign laws and regulations could significantlygovern the management of wastes, including the treatment, storage and disposal of hazardous wastes. RCRA imposes stringent operating requirements, and liability for failure to meet such requirements, on a person who is either a “generator” or “transporter” of hazardous waste or an “owner” or “operator” of a hazardous waste treatment, storage or disposal facility. RCRA and many state counterparts specifically exclude from the definition of hazardous waste drilling fluids, produced waters, and other wastes associated with the exploration, development, or production of crude oil and natural gas. As a result, our operations generate minimal quantities of RCRA hazardous wastes. We do not believe the current costs of managing our wastes, as they are presently classified, to be significant. However, any repeal or modification of this or similar exemption in similar state statutes, would increase the volume of hazardous waste we are required to manage and dispose of, and would cause us, as well as our competitors, to incur increased operating expenses with respect to our US operations.
Water Discharges. The US Federal Water Pollution Control Act of 1972, as amended, also known as the “Clean Water Act,” and similar state laws and regulations impose restrictions and controls on the discharge of pollutants into federal and state waters. These laws also regulate the discharge of storm water in process areas. Pursuant to these laws and regulations, we are required to obtain and maintain approvals or permits for the discharge of wastewater and storm water. In addition, the USCG has promulgated requirements for ballast water management as well as supplemental ballast water requirements, which includes limits and, in some cases, water treatment requirements applicable to specific discharge streams, such as deck runoff, bilge water and gray water. Further, in October 2020, the United States Environmental Protection Agency (“EPA”) published proposed national standards of performance for incidental discharges pursuant to the Vessel Incidental Discharge Act. The proposed rule would establish discharge standards for a range of vessels, including mobile offshore drilling units. We do not anticipate that compliance with these laws and regulations will cause a material impact on our operations or financial condition.
Air Emissions. The US Federal Clean Air Act and associated state laws and regulations restrict the emission of air pollutants from many sources, including oil and natural gas operations. New facilities may be required to obtain permits before operations can commence, and existing facilities may be required to obtain additional permits, and incur capital costs, in order to remain in compliance. Federal and state regulatory agencies can impose administrative, civil and criminal penalties for non-compliance with air permits or other requirements of the Clean Air Act and associated state laws and regulations. In general, we believe that compliance with the Clean Air Act and similar state laws and regulations will not have a material impact on our operations or financial condition.
Climate Change.Climate change is an environmental, social and economic challenge facing everyone today. We are committed to continuous improvement and a sustainable energy future, supported by our efforts to protect the environment throughout our operations and safely provide reliable and efficient services to allow access to resources essential for human and economic prosperity. There is increasing attention concerning the issue of climate change and the effect of greenhouse gas (“GHG”) emissions. The EPA regulates the permitting of GHG emissions from stationary sources under the Clean Air Act’s Prevention of Significant Deterioration and Title V permitting programs, which require the use of “best available control technology” for GHG emissions from new and modified major stationary sources, which can sometimes include our rigs. The EPA has also adopted rules requiring the monitoring and reporting of GHG emissions from specified sources in the United States, including, among other things, certain onshore and offshore oil and natural gas production facilities, on an annual basis.
Moreover, in 2005, the Kyoto Protocol to the 1992 United Nations Framework Convention on Climate Change, which establishes a binding set of emission targets for GHGs, became binding on all countries that had ratified it. In 2015, the United Nations (“U.N.”) Climate Change Conference in Paris resulted in the creation of the Paris Agreement. In September 2016, the US deposited its instrument of acceptance of the Paris Agreement, which later entered into force on November 4, 2016. The Paris Agreement requires countries to review and “represent a progression” in their nationally determined contributions, which set emissions reduction goals, every five years beginning in 2020. In November 2019, the US submitted formal notification to the U.N. of its decision to withdraw from the Paris Agreement, which took effect on November 4, 2020. However, in January 2021, shortly after Joseph Biden was sworn into office as the President of the United States, a series of executive orders were issued regarding climate change, which in part led to the US again depositing an instrument of acceptance of the Paris Agreement, which thereafter re-entered into force for the US on February 19, 2021. The terms of the Paris Agreement and the executive orders are expected to result in additional regulations or changes to existing regulations, which could have a material adverse effect on our business financial conditionin the US and resultsthat of operations.our customers. In addition, we may be requiredincentives to post additional surety bonds to secure performance, tax, customs and other obligations relating to our rigsconserve energy or use alternative energy sources in jurisdictions where bonding requirements are already in effect and in other jurisdictions where we may operate in the future. These requirements would increase the cost of operating in these countries, which could materially adversely affect our business, financial condition and results of operations.
In response to the Macondo well blowout incident in April 2010, the U.S. Department of Interior, through the BOEM and BSEE, began an overhaulmany of the offshore oil and natural gas regulatory process that significantly impacted oil and gas development regulated by the United States. From time to time, new rules, regulations and requirements have been proposed and implemented by BOEM, BSEE or the United States Congress that could materially limit or prohibit, and increase the cost of, offshore drilling. For example, in July 2016, BOEM and BSEE finalized a rule revising and adding requirements for drilling on the U.S. Arctic Outer Continental Shelf. Similarly, in April 2016, BSEE announced a final blowout preventer systems and well control rule. However, in December 2017, BSEE published a proposed rule that would revise a number of the requirements in the blowout preventer systems and well control rule. BOEM also released a new Notice to Lessees and Operators in the Outer Continental Shelf ("NTL") in September 2016 that updates offshore bonding requirements. This update eliminates waivers of supplemental bonding and prohibits a company from relying on the financial strength of co-lessees unless co-lessees agree to allocate BOEM-determined self-insurance to the lease. In January 2017, BOEM extended the implementation timeline for the NTL by six months. In May 2017, the Secretary of the Interior directed BOEM to review the NTL and provide a report describing the results of the review and options for revising or rescinding the NTL. BOEM again extended the implementation timeline for the NTL in June 2017. If the NTL goes into effect, these new bonding requirements may increase our customers’ operating costs and impact our customers’ ability to obtain leases, thereby, reducing demand for our services. We are also subject to increasing regulatory requirements and scrutiny in the North Sea jurisdictions and other countries. These new rules, regulations and requirements, including the adoption of new safety requirements and policies relating to the approval of drilling permits, restrictions on oil and gas development and production activities in the U.S. Gulf of Mexico and elsewhere, implementation of safety and environmental management systems, mandatory third party compliance audits, and the promulgation of numerous Notices to Lessees or similar new regulatory requirements outside of theUnited States, have impacted and may continue to impact our operations by causing increased costs, delays and operational restrictions. In addition to these rules, regulations and requirements, the U.S. federal government is considering newlegislation that could impose additional equipment and safety requirements on operators and drilling contractors in the United States, as well as regulations relating to the protection of the environment. If the new regulations, policies, operating procedures and possibility of increased legal liability resulting from the adoption or amendment of rules and regulations applicable to our operations in the United States or other jurisdictions are viewed by our current or future customers as a significant


impairment to expected profitability on projects, then they could discontinue or curtail their offshore operations in the impacted region, thereby adversely affecting our operations by limiting drilling opportunities or imposing materially increased costs.
Adverse effects may continue as a result of the uncertainty of ongoing inquiries, investigations and court proceedings, or additional inquiries and proceedings by federal or state regulatory agencies or private plaintiffs. In addition, we cannot predict the outcome of any of these inquiries or whether these inquiries will lead to additional legal proceedings against us, civil or criminal fines or penalties, or other regulatory action, including legislation or increased permitting requirements. Legal proceedings or other matters against us, including environmental matters, suits, regulatory appeals, challenges to our permits by citizen groups and similar matters, might result in adverse decisions against us. The result of such adverse decisions, both individually or in the aggregate, could be material and may not be covered fully or at all by insurance.
Operational interruptions or maintenance or repair work may cause our customers to suspend or reduce payment of dayrates until operation of the respective drilling rig is resumed, which may lead to loss of revenue or termination or renegotiation of the drilling contract.
If our drilling rigs are idle for reasons that are not related to the ability of the rig to operate, our customers are entitled to pay a waiting, or standby, rate lower than the full operational rate. In addition, if our drilling rigs are taken out of service for maintenance and repair for a period of time exceeding the scheduled maintenance periods set forth in our drilling contracts, we will not be entitled to payment of dayrates until the rig is able to work. Several factors could cause operational interruptions, including:
breakdowns of equipment and other unforeseen engineering problems;
work stoppages, including labor strikes;
shortages of material and skilled labor;
delays in repairs by suppliers;
surveys by government and maritime authorities;
periodic classification surveys;
inability to obtain permits;
severe weather, strong ocean currents or harsh operating conditions; and
force majeure events.
If the interruption of operations were to exceed a determined period due to an event of force majeure, our customers have the right to pay a rate that is significantly lower than the waiting rate for a period of time, and, thereafter, may terminate the drilling contracts related to the subject rig. Suspension of drilling contract payments, prolonged payment of reduced rates or termination of any drilling contract as a result of an interruption of operations as described herein could materially adversely affect our business, financial condition and results of operations.
As a result of our significant cash flow needs, we may be required to incur additional indebtedness, and in the event of lost market access, may have to delay or cancel discretionary capital expenditures.
Our cash flow needs, both in the short-term and long-term, may include the following:
normal recurring operating expenses;
planned and discretionary capital expenditures; and
repayment of debt and interest.
In the future, we may require funding for capital expenditures that is beyond the amount available to us from cash generated by our operations, cash on hand and borrowings under our existing Credit Facilities. We may raise such additional capital in a number of ways, including accessing capital markets, obtaining additional lines of credit or disposing of assets. However, we can provide no assurance that any of these options will be available to us on terms acceptable to us or at all.
Our debt instruments could limit our operations and our debt level may limit our flexibility to obtain financing and pursue business opportunities. Our ability to obtain financing or to access the capital markets may be limited by our financial condition and our credit ratings at the time of any such financing and the covenants in our existing debt agreements, as well as by adverse market conditions resulting from, among other things, a depressed oil price, general economic conditions and uncertainties that are beyond our control. Even if we are successful in obtaining additional capital through debt financings, incurring additional indebtedness may significantly increase our interest expense and may reduce our flexibility to respond to changing business and economic conditions or to fund working capital needs, because we will require additional funds to service our outstanding indebtedness.
We may delay or cancel discretionary capital expenditures, which could have certain adverse consequences, including delaying upgrades or equipment purchases that could make the affected rigs less competitive, adversely affect customer relationships and negatively impact our ability to contract such rigs.


We may have difficulty obtaining or maintaining insurance in the future and our insurance coverage and contractual indemnity rights may not protect us against all the risks and hazards we face.
We do not procure insurance coverage for all of the potential risks and hazards we may face. Furthermore, no assurance can be given that we will be able to obtain insurance against all of the risks and hazards we face or that we will be able to obtain or maintain adequate insurance at rates and with deductibles or retention amounts that we consider commercially reasonable.
Our insurance carriers may interpret our insurance policies such that they do not cover losses for which we make claims. Our insurance policies may also have exclusions of coverage for some losses. Uninsured exposures may include expatriate activities prohibited by U.S. laws, radiation hazards, certain loss or damage to property onboard our rigs and losses relating to shore-based terrorist acts or strikes. Furthermore, the damage sustained to offshore oil and gas assets in the United States as a result of hurricanes has negatively impacted certain aspects of the energy insurance market, resulting in more restrictive and expensive coverage for U.S. named windstorm perils due to the price or lack of availability of coverage. Accordingly, we have in the past self-insured the rigs in the U.S. Gulf of Mexico for named windstorm perils. We currently have U.S. windstorm coverage for most of our U.S. fleet subject to limit, but will continue to monitor the insurance market conditions in the future and may decide not to, or be unable to, purchase named windstorm coverage for some or all of the rigs operating in the U.S. Gulf of Mexico.
Under our drilling contracts, liability with respect to personnel and property is customarily assigned on a “knock-for-knock” basis, which means that we and our customers assume liability for our respective personnel and property, irrespective of the fault or negligence of the party indemnified. Although our drilling contracts generally provide for indemnification from our customers for certain liabilities, including liabilities resulting from pollution or contamination originating below the surface of the water, enforcement of these contractual rights to indemnity may be limited by public policy and other considerations and, in any event, may not adequately cover our losses from such incidents. There can also be no assurance that those parties with contractual obligations to indemnify us will necessarily be in a financial position to do so. During depressed market periods such as the one in which we currently operate, the contractual indemnity provisions we are able to negotiate in our drilling contracts may require us to assume more risk than we would during normal market periods.
Although we maintain insurance in the geographic areas in which we operate, pollution, reservoir damage and environmental risks generally are not fully insurable. Our insurance policies may not adequately cover our losses or may have exclusions of coverage for some losses. We do not have insurance coverage or rights to indemnity for all risks, including loss of hire insurance on most of the rigs in our fleet. Uninsured exposures may include expatriate activities prohibited by U.S. laws and regulations, radiation hazards, cyber risks, certain loss or damage to property onboard our rigs and losses relating to shore-based terrorist acts or strikes. If a significant accident or other event occurs and is not fully covered by insurance or contractual indemnity, it could adversely affect our business, financial condition and results of operations.
Our information technology systems and those of our service providers are subject to cybersecurity risks and threats.
We depend on information technology systems that we manage, and others that are managed by our third-party service and equipment providers, to conduct our day-to-day operations, including critical systems on our drilling units, and these systems are subject to risks associated with cyber incidents or attacks. It has been reported that unknown entities or groups have mounted cyber-attacks on businesses and other organizations solely to disable or disrupt computer systems, disrupt operations and, in some cases, steal data. Due to the nature of cyber-attacks, breaches to our service or equipment providers’ systems could go unnoticed for a prolonged period of time. These cybersecurity risks could disrupt our operations and result in downtime, loss of revenue, or the loss, theft, corruption or unauthorized release of critical data of us or those with whom we do business as well as result in higher costs to correct and remedy the effects of such incidents. If our or our service or equipment providers’ systems for protecting against cyber incidents or attacks prove to be insufficient and an incident were to occur, it could have a material adverse effect on our business, financial condition, results of operations or cash flows. Currently, we do not carry insurance for losses related to cybersecurity attacks, and may elect to not obtain such insurance in the future.
A loss of a major tax dispute or a successful tax challenge to our operating structure, intercompany pricing policies or the taxable presence of our subsidiaries in certain countries could result in a higher tax rate on our worldwide earnings, which could result in a material adverse effect on our financial condition and results of operations.
Income tax returns that we file will be subject to review and examination. We will not recognize the benefit of income tax positions we believe are more likely than not to be disallowed upon challenge by a tax authority. If any tax authority successfully challenges our operational structure, intercompany pricing policies or the taxable presence of our subsidiaries in certain countries, if the terms of certain income tax treaties are interpreted in a manner that is adverse to our structure, or if we lose a material tax dispute in any country, our effective tax rate on our worldwide earnings could increase substantially and result in a material adverse effect on our financial condition.
Our consolidated effective income tax rate may vary substantially from one reporting period to another.
We cannot provide any assurances as to what our 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 UK, 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 any reclassification or other matter (such as changes in applicable accounting rules) that increases 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. 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. 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. If we are unable to mitigate the negative consequences of any change in law, audit, business activity or other matter, this could cause our consolidated effective income tax rate to increase and cause a material adverse effect on our financial position, operating results and/or cash flows.
Our operations are subject to numerous laws and regulations relating to the protection of the environment and of human health and safety, and compliance with these laws and regulations could impose significant costs and liabilities that exceed our current expectations.
Substantial costs, liabilities, delays and other significant issues could arise from environmental, health and safety laws and regulations covering our operations, and we may incur substantial costs and liabilities in maintaining compliance with such laws and regulations. Our operations are subject to extensive international conventions and treaties, and national or federal, state and local laws and regulations, governing environmental protection, including with respect to the discharge of materials into the environment and the security of chemical and industrial facilities. These laws govern a wide range of environmental issues, including:
the release of oil, drilling fluids, natural gas or other materials into the environment;
air emissions from our drilling rigs or our facilities;
handling, cleanup and remediation of solid and hazardous wastes at our drilling rigs or our facilities or at locations to which we have sent wastes for disposal;
restrictions on chemicals and other hazardous substances; and
wildlife protection, including regulations that ensure our activities do not jeopardize endangered or threatened animals, fish and plant species, nor destroy or modify the critical habitat of such species.
Various governmental authorities have the power to enforce compliance with these laws and regulations and the permits issued under them, oftentimes requiring difficult and costly actions. Failure to comply with these laws, regulations and permits, or the release of oil or other materials into the environment, may result in the assessment of administrative, civil and criminal penalties, the imposition of remedial obligations, the imposition of stricter conditions on or revocation of permits, the issuance of moratoria or injunctions limiting or preventing some or all of our operations, delays in granting permits and cancellation of leases, or could affect our relationship with certain consumers.
There is an inherent risk of the incurrence of environmental costs and liabilities in our business, some of which may be material, due to the handling of our customers’ hydrocarbon products as they are gathered, transported, processed and stored, air emissions related to our operations, historical industry operations, and water and waste disposal practices. For example, we, as an operator of mobile offshore drilling units in navigable U.S. waters and certain offshore areas, including the U.S. Outer Continental Shelf, are liable for damages and for the cost of removing oil spills for which we may be held responsible, subject to certain limitations. Our operations may involve the use or handling of materials that are classified as environmentally hazardous. Environmental laws and regulations may expose us to liability for the conduct of or conditions caused by others or for acts that were in compliance with all applicable laws at the time they were performed. Joint, several or strict liability may be incurred without regard to fault under certain environmental laws and regulations for the remediation of contaminated areas and in connection with past, present or future spills or releases of natural gas, oil and wastes on, under, or from past, present or future facilities. Private parties may have the right to pursue legal actions to enforce compliance as well as to seek damages for non-compliance with environmental laws and regulations or for personal injury or property damage arising from our operations. In addition, increasingly strict laws, regulations and enforcement policies could materially increase our compliance costs and the cost of any remediation that may become necessary. Our insurance may not cover all environmental risks and costs or may not provide sufficient coverage if an environmental claim is made against us.
Our business may be adversely affected by increased costs due to stricter pollution control equipment requirements or liabilities resulting from non-compliance with required operating or other regulatory permits. Also, we might not be able to obtain or maintain from time to time all required environmental regulatory approvals for our operations. If there is a delay in obtaining any required environmental regulatory approvals, or if we fail to obtain and comply with them, the operation or construction of our facilities could be prevented or become subject to additional costs. In addition, the steps we could be required to take to bring certain facilities into regulatory compliance could be prohibitively expensive, and we might be required to shut down, divest or alter the operation of those facilities, which might cause us to incur losses.
We make assumptions and develop expectations about possible expenditures related to environmental conditions based on current laws and regulations and current interpretations of those laws and regulations. If the interpretation of laws or regulations, or the laws and regulations


themselves, change, our assumptions may change, and new capital costs may be incurred to comply with such changes. In addition, new environmental laws and regulations might adversely affect our operations, as well as waste management and air emissions. For instance, governmental agencies could impose additional safety requirements, which could affect our profitability. Further, new environmental laws and regulations might adversely affect our customers, which in turn could affect our profitability.
Finally, although some of our drilling rigs will be separately owned by our subsidiaries, under certain circumstances a parent company and all of the unit-owning affiliates in a group under common control engaged in a joint venture could be held liable for damages or debts owed by one of the affiliates, including liabilities for oil spills under environmental laws. Therefore, it is possible that we could be subject to liability upon a judgment against us or any one of our subsidiaries.
Reactivation, refurbishment, conversion or upgrades of rigs are subject to risks, including delays and cost overruns, which could have an adverse impact on our available cash resources and results of operations.
We will continue to make upgrades, refurbishment and repair expenditures to our fleet from time to time, some of which may be unplanned. In addition, we may reactivate rigs that have been cold or warm stacked. Our customers may also require certain shipyard reliability upgrade projects for our rigs. These projects and other efforts of this type are subject to risks of cost overruns or delays inherent in any large construction project as a result of numerous factors, including the following:
shortages of equipment, materials or skilled labor;
work stoppages and labor disputes;
unscheduled delays in the delivery of ordered materials and equipment;
local customs strikes or related work slowdowns that could delay importation of equipment or materials;
weather interferences;
difficulties in obtaining necessary permits or approvals or in meeting permit or approval conditions;
design and engineering problems;
inadequate regulatory support infrastructure in the local jurisdiction;
latent damages or deterioration to hull, equipment and machinery in excess of engineering estimates and assumptions;
unforeseen increases in the cost of equipment, labor and raw materials, particularly steel;
unanticipated actual or purported change orders;
client acceptance delays;
disputes with shipyards and suppliers;
delays in, or inability to obtain, access to funding;
shipyard availability, failures and difficulties, including as a result of financial problems of shipyards or their subcontractors; and
failure or delay of third-party equipment vendors or service providers.
The failure to complete a rig reactivation, repair, upgrade, refurbishment or new construction on time, or at all, or the inability to complete a rig conversion or new construction in accordance with its design specifications, may result in loss of revenues, penalties, or delay, renegotiation or cancellation of a drilling contract or the recognition of an asset impairment. Additionally, capital expenditures for rig reactivation, repair, upgrade, refurbishment and construction projects could materially exceed our planned capital expenditures. Moreover, when our rigs are undergoing upgrade, refurbishment and repair, they may not earn a dayrate during the period they are out of service. If we experience substantial delays and cost overruns in our shipyard projects, it could have a material adverse effect on our business, financial condition and results of operations. We currently have no new rigs under construction.
Acts of terrorism, piracy and political and social unrest could affect the markets for drilling services, which may have a material adverse effect on our results of operations.
Acts of terrorism and social unrest, brought about by world political events or otherwise, have caused instability in the world’s financial and insurance markets in the past and may occur in the future. Such acts could be directed against companies such as ours. In addition, acts of terrorism, piracy and social unrest could lead to increased volatility in prices for crude oil and natural gas and could affect the markets for drilling services. Insurance premiums could increase and coverage may be unavailable in the future. Government regulations may effectively preclude us from engaging in business activities in certain countries. These regulations could be amended to cover countries where we currently operate or where we may wish to operate in the future.future, could have a negative impact on our business in those countries and worldwide. See Part I, Item1A, “Risk Factors—Regulatory and Legal Risks— Governmental laws and regulations may add to our costs, result in delays, or limit our drilling activity” for additional information.
Our drilling contracts do not generally provide indemnification against lossCountries in the European Union (“EU”) implement the U.N.’s Kyoto Protocol on GHG emissions through the Emissions Trading System (“ETS”). The ETS program establishes a GHG “cap and trade” system for certain industry sectors, including power generation at some offshore facilities. Total GHG from these sectors is capped, and the cap is reduced over time to achieve GHG reductions from these sectors. In September 2020, the European Commission presented a plan to increase the EU’s GHG reduction target to at least 55% by 2030 in accordance with the European Green Deal. In order to reach this goal, the European Commission has proposed potential revisions and expansions of the EU ETS.

In addition, the United Kingdom (“UK”) government implemented its own ETS in January 2021 to replace the UK’s participation in the EU ETS. The UK has also introduced an auction price floor to prevent carbon prices from dropping below a set level during the initial implementation of the UK ETS. The cost of compliance with the UK ETS and the EU ETS can be expected to increase over time. Additional member state climate change legislation may result in potentially material capital assets or loss of revenues resulting from acts of terrorism, piracy or political or social unrest. expenditures.
We have limited insurancedetermined that combustion of ultra-low sulfur fuel oil aboard all of our vessels worldwide (Scope 1) is the Company’s primary source of GHG emissions, which includes carbon dioxide, methane and nitrous oxide. Based upon the emissions calculation factor provided by the original equipment manufacturer for each engine type utilized on our vessels, for the year ended December 31, 2020, our estimated carbon dioxide equivalent (“C02e”) gas emissions were 960,593 tons as compared to 1,063,925 tons for the year ended December 31, 2019. When expressed as an intensity measure of tons of C02e gas emissions per contract day for our assetsvessels worldwide, the intensity measure for December 31, 2020 and 2019 was 174.58 and 156.85, respectively.
The increase of our C02e intensity average from 2019 to 2020 is largely attributed to fewer contracted days in 2020 for several of our vessels that have lower operating energy demands, while our larger vessels that require more energy collectively operated for more contracted days during the same period.
Noble utilizes emission coefficient factors directly from the OEM engine manufacturers carefully calculated per engine type and fuel usage to determine emissions generated from our direct operations throughout the year. While OEM provided coefficients are one method of calculation, there are other relevant industry and regulatory approved standards for calculating GHG production that lead us to a broader understanding of our GHG impact. Each of these methods of calculation vary in assumptions made during the calculation process. By providing coverage for physical damage losses resulting from risks, such as terrorist acts, piracy, vandalism, sabotage, civil unrest, expropriation and acts of war, and we do not carry insurance for loss of revenues resulting from such risks.


Failure to attract and retain skilled personnel or an increase in personnel costs could adversely affect our operations.
We require skilled personnel to operate and provide technical services and support for our drilling units. In the past, during periods of high demand for drilling services and increasing worldwide industry fleet size, shortages of qualified personnel have occurred. During periods of low demand,these additional calculations such as the oneEnvironmental Emissions Monitoring System (EEMS), we feel we are currently experiencing, there are layoffsmore prepared to compare our emissions data to those relevant industry standards and accurately compare to peer performance with a higher degree of qualified personnel, who often find worktransparency.
Our Scope 1 C02e gas emissions reporting has been prepared with competitors or leavereference to the industry.  As a result, once market conditions improve, we may face shortages of qualified personnel, which would impair our ability to attract qualified personnel for our new or existing drilling units, impair the timeliness and quality of our work and create upward pressure on personnel costs, any of which could adversely affect our operations.

Supplier capacity constraints or shortages in parts or equipment, 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 used in our drilling operations exposes us to volatilityrequirements set out in the quality, priceUK Companies Act 2006 Regulations 2013, the Environmental Reporting Guidelines (June 2013) issued by the Department for Environment Food & Rural Affairs, the World Resources Institute and availabilityWorld Business Council for Sustainable Development GHG Protocol Corporate Accounting and Reporting Standard Revised and the International Organization for Standardization (“ISO”) 14064-1, “Specification with guidance at the organizational level for quantification and reporting of such items. Certain specialized partsgreenhouse gas emissions and equipment we useremovals (2006).”
Worker Safety. The US Occupational Safety and Health Act (“OSHA”) and other similar laws and regulations govern the protection of the health and safety of employees. The OSHA hazard communication standard, EPA community right-to-know regulations under Title III of CERCLA and similar state statutes require that information be maintained about hazardous materials used or produced in our operations mayand that this information be available onlyprovided to employees, state and local governments and citizens. EU member states have also adopted regulations pursuant to EU Directive 2013/30/EU, on the safety of offshore oil and gas operations within the exclusive economic zone (which can extend up to 200 nautical miles from a singlecoast) or small number of suppliers. A disruptionthe continental shelf. We believe that we are in substantial compliance with OSHA requirements and EU directive 2013/30/EU (as well as the extensive current health and safety regimes implemented in the deliveries from such third-party suppliers, capacity constraints, production disruptions, price increases, defects or quality-control issues, recalls or other decreased availability or servicing of partsmember states in which we operate), but future developments could require the Company to incur significant costs to comply with the directive's implementation.
International Regulatory Regime.The IMO provides international regulations governing shipping and equipment could adversely affect our ability to meet our commitments to customers, adversely impact our operationsinternational maritimetrade. IMO regulations have been widely adopted by U.N. member countries, and revenues by resulting in uncompensated downtime, reduced day rates or the cancellation or termination of contracts, or increase our operating costs.
Unionization efforts and labor regulations in certain countriessome jurisdictions in which we operate, could materially increase our coststhese regulations have been expanded upon. The requirements contained in the International Management Code for the Safe Operation of Ships and for Pollution Prevention, or limit our flexibility.
CertainISM Code, promulgated by the IMO, govern much of our employeesdrilling operations. Among other requirements, the ISM Code requires the party with operational control of a vessel to develop an extensive safety management systemthat includes, among other things, the adoption of a safety and contractorsenvironmental protection policy setting forth instructions and procedures for operating its vessels safely and describing procedures for responding to emergencies.
The IMO has also adopted and revised MARPOL, including Annex VI to MARPOL, which limits the main air pollutants contained in exhaust gas from ships, including sulfur oxides (“SOx”) and nitrous oxides (“NOx”), prohibits deliberate emissions of ozone depleting substances (“ODS”), regulates shipboard incineration and the emissions of volatile organic compounds (“VOC”) from tankers, sets a progressive reduction globally in emissions of SOx, NOx and particulate matter, introduces emission control areas (“ECAs”) to reduce emissions of those air pollutants further in designated sea areas, and effective from January 1, 2020, reduces the global sulfur limit in fuel oil from the current 3.50% to 0.50% m/m (mass by mass) sulfur content. Prior to January 1, 2020, our rigs were operating and continue to operate with low sulfur fuel oil at or below the global limits of 0.50%.
The IMO has also negotiated international conventions that impose liability for oil pollution in international markets are represented by labor unions or work under collective bargaining or similar agreements, which are subject to periodic renegotiation. Efforts may be made from time to time to unionize portions of our workforce. In addition, we may be subject to strikes or work stoppageswaters and other labor disruptions in the future. Additional unionization efforts, new collective bargaining agreements or work stoppages could materially increase our costs, reduce our revenues or limit our operational flexibility.
Any failure to comply with the complex laws and regulations governing international trade could adversely affect our operations.
The shipment of goods, services and technology across international borders subjects our business to extensive trade laws and regulations. Import activities are governed by unique customs laws and regulations in eachterritorial waters of the countries of operation. 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 economic sanctions against certain countries, persons and other entities that may restrict or prohibit transactions involvingsignatory to such countries, persons and entities. U.S. sanctions, in particular, are targeted against certain countries that are heavily involved in the petroleum and petrochemical industries, which includes drilling activities.
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. Any failure to comply with applicable legal and regulatory trading obligations could also result in criminal and civil penalties and sanctions, such as fines, imprisonment, debarment from government contracts, seizure of shipments and loss of import and export privileges.
Currently, we do not, nor do we intend to, operate in countries that are subject to significant sanctions and embargoes imposed by the U.S. government or identified by the U.S. government as state sponsors of terrorism,conventions such as the Crimean regionBallast Water Management Convention, (the “BWM Convention”) and the International Convention for Civil Liability for Bunker Oil Pollution Damage of 2001 (the “Bunker Convention”). The BWM Convention's implementing regulations call for a phased introduction of mandatory ballast of water exchange requirements, to be replaced in time with a requirement for

mandatory ballast water treatment. The Bunker Convention provides a liability, compensation and compulsory insurance system for the Ukraine, Cuba, Iran, North Korea, Sudanvictims of oil pollution damage caused by spills of bunker oil. We believe that all of our drilling rigs are currently compliant in all material respects with these regulations. However, the IMO continues to review and Syria. The U.S. sanctions and embargo laws andintroduce new regulations. It is impossible to predict what additional regulations, vary in their application, as they do not all apply to the same covered persons or proscribe the same activities, and such sanctions and embargo laws and regulationsif any, may be amended or strengthened over time. Although we believe that we will be in compliance with all applicable sanctionspassed by the IMO and embargo laws and regulations at the filing date, and intend to maintainwhat effect, if any, such compliance, there can be no assurance that we will be in compliance in the future, particularly as the scope of certain laws may be unclear and may be subject to changing interpretations. Any such violation could result in fines or other penalties and could result in some investors deciding, or being required, to divest their interest, or not to invest, in us. In addition, certain institutional investorsregulation may have investment policies or restrictions that prevent them from holding securities of companies that have contracts with countries identified by the U.S. government as state sponsors of terrorism. In addition, our reputation and the market for our securities may be adversely affected if we engage in certain other activities, such as entering into drilling contracts with individuals or entities in countries subject to significant U.S. sanctions and embargo laws that are not controlled by the governments of those countries, or engaging in operations associated with those countries pursuant to contracts with third parties that are unrelated to those countries or entities controlled by their governments.


Pension expenses associated with our retirement benefit plans may fluctuate significantly depending upon changes in actuarial assumptions, future investment performance of plan assets and legislative or other regulatory actions.
A portion of our current and retired employee population is covered by pension and other post-retirement benefit plans, the costs of which are dependent upon various assumptions, including estimates of rates of return on benefit plan assets, discount rates for future payment obligations, mortality assumptions, rates of future cost growth and trends for future costs. In addition, funding requirements for benefit obligations of our pension and other post-retirement benefit plans are subject to legislative and other government regulatory actions. Future changes in estimates and assumptions associated with our pension and other post-retirement benefit plans could have a material adverse effect on our financial condition, results of operations, cash flows and/or financial disclosures.operations.
Fluctuations in exchange rates and nonconvertibility of currencies could result in losses to us.
We may experience currency exchange losses when revenues are received or expenses are paid in nonconvertible currencies, when we do not hedge an exposure to a foreign currency, when the result of a hedge is a loss or if any counterparty to our hedge were to experience financial difficulties. We may also incur losses as a result of an inability to collect revenues due to a shortage of convertible currency available to the country of operation, controls over currency exchange or controls over the repatriation of income or capital.
We are subject to litigation that could have an 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, asbestos and other toxic tort claims, environmental claims or proceedings, employment matters, governmental claims for taxes or duties, and other litigation that arises in the ordinary course of our business. Although we intend to defend these 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 may have an adverse effect on us because of potential negative outcomes, costs of attorneys, the allocation of management’s time and attention, and other factors.
We are a holding company, and we are dependent upon cash flow from subsidiaries to meet our obligations.
We currently conduct our operations through our subsidiaries, and our operating income and cash flow are generated by our subsidiaries. As a result, cash we obtain from our subsidiaries is the principal source of funds necessary to meet our debt service obligations. Unless they are guarantors of our indebtedness, our subsidiaries do not have any obligation to pay amounts due on our indebtedness or to make funds available for that purpose. Contractual provisions or laws, as well as our subsidiaries’ financial condition and operating requirements, may also limit our ability to obtain the cash that we require from our subsidiaries to pay our debt service obligations. Applicable tax laws may also subject such payments to us by our subsidiaries to further taxation.

Drilling Fleet
Noble is a leading offshore drilling contractor for the oil and gas sector. Noble owns and operates one of the most modern, versatile and technically advanced fleets of mobile offshore drilling units in the offshore drilling industry. Noble provides, through its subsidiaries, contract drilling services with a fleet of 2819 offshore drilling units, consisting of eight drillships, six semisubmersiblesseven floaters and 1412 jackups at the date of this report, focused largely on ultra-deepwater and high-specification drilling opportunities in both established and emerging regions worldwide. Each type of drilling rig is described further below. Several factors determine the type of unit most suitable for a particular job, the most significant of which include the water depth and the environment of the intended drilling location, whether the drilling is being done over a platform or other structure, and the intended well depth. At December 31, 2020, our fleet was located in Far East Asia, the Middle East, the North Sea, Oceania, South America and the US Gulf of Mexico.
DrillshipsFloaters
Our floating fleet consists of the following:
A drillship is a type of floating drilling unit that is based on the ship-based hull of the vessel and equipped with modern drilling equipment that gives it the capability of easily transitioning from various worldwide locations and carrying high capacities of equipment while being able to drill ultra-deepwater oil and gas wells in up to 12,000 feet of water. Drillships can stay directly over the drilling location without anchors in open seas using a dynamic positioning system (“DPS”), which coordinates position references from satellite signals and acoustic seabed transponders with the drillship's six to eight thrustersthrusters to keep the ship directly over the well that is being drilled. Drillships are selected to drill oil and gas wells


for programs that require a high level of simultaneous operations, where drilling loads are expected to be high, or where there are occurrences of high ocean currents, where the drillship's hull shape is the most efficient. There are currently eight drillships in Noble's fleet consists of six drillships capable of water depths from 8,20010,000 feet to 12,000 feet.
Semisubmersibles
Semisubmersible drilling units are designed as a floating drilling platform incorporating one or several pontoon hulls, which are submerged in the water to lower the center of gravity and make this type of drilling unit exceptionally stable in the open sea. Semisubmersible drilling units are generally categorized in terms of the water depth in which they are capable of operating, from the mid-water range of 300 feet to 4,000 feet, the deepwater range of 4,000 feet to 7,500 feet, to the ultra-deepwater range of 7,500 feet to 12,000 feet as well as by their generation, or date of construction. This type of drilling unit typically exhibits excellent stability characteristics, providing a stable platform for drilling in even rough seas. Semisubmersible drilling units hold their position over the drilling location using either an anchored mooring system or a DPS and may be self-propelled. Noble'sNoble’s fleet consists of sixone moored ultra-deepwater semisubmersible drilling units, three of which are equipped with mooring systems and three of which utilize DPS, with fleet diversity to operate in mid-water, deepwater and ultra-deepwater depth ranges with high levels of efficiency.unit.

Jackups
Noble'sNoble’s fleet of modern, high-specification jackup drilling units givegives us the flexibility to provide drilling solutions to our customers who have drilling requirements in the shallower waters of the continental shelf, in depths ranging from less than 100 feet to as deep as 500 feet.feet of water with drilling hookloads up to 2,500,000. Jackup rigs can be used in open water exploration locations, as well as over fixed, bottom-supported platforms. A jackup drilling unit is a towed mobile vessel consisting of a floating hull equipped with three or four legs, which are lowered to the seabed at the drilling location. The hull is then elevated out of the water by the jacking system using the legs to support weight of the hull and drilling equipment against the seabed. Once the hull is elevated to the desired level, or jacked up, the drilling package can be extended out over an existing production platform or the open water location and drilling can commence. Noble'sNoble’s fleet of 1412 jackups varies from three standardtwo units capable of drilling in up to 300375 feet of water to premium and high-specification units capable of drilling in up to 500 feet of water with drilling hookloads greater than 2,500,000 pounds.

Market

The offshore contract drilling industry is a highly competitive and cyclical business. Demand for offshore drilling services is driven by the offshore exploration and development programs of oil and gas operators, which in turn are influenced by many factors, including, but not limited to, the price and price stability of oil and gas, the availability and relative cost of offshore oil and gas resources within the oil and gas portfolio of each operator, general global economic conditions, energy demand, the operator’s strategy toward renewable energy sources, environmental considerations and national oil and gas policy.

In the provision of offshore contract drilling services, competition is largely governed by price but involves numerous other factors as well. Rig availability, location, suitability and technical specifications are the primary factors in determining which rig is qualified for a job, and additional factors are considered when determining which contractor is awarded a job, including experience of the workforce, efficiency, safety performance record, condition of equipment, operating integrity, reputation, industry standing and client relations. In addition to having one of the newest fleets in the industry among our peer companies, we strive to keep our assets well-maintained and technologically competitive.
FacilitiesWe maintain a global operational presence and compete in many of the major offshore oil and gas basins worldwide. All our drilling rigs are mobile, and we may mobilize our drilling rigs among regions for a variety of reasons, including to respond to customer requirements. We compete in both the jackup and floating rig market segments, each of which may have different supply and demand dynamics at a given period in time or in different regions.
Since late 2014, the offshore drilling industry has experienced a severe and prolonged downturn driven by a combination of an oversupply of drilling rigs, weak and volatile crude oil prices exacerbated in early 2020 by production level disagreements by OPEC+, reductions in global offshore exploration and development activities, and the impacts of COVID-19.
The global mitigation efforts associated with preventing the spread of COVID-19 have significantly slowed global economic activity, leading to a precipitous drop in oil demand in 2020. As the year progressed, some countries began to ease lock-down restrictions, resulting in an increase in oil demand; however, current demand and near-term demand forecasts still lag pre-COVID-19 demand levels. As the demand imbalance played out during the year, crude price volatility lessened as OPEC+ agreed to production level cuts through early 2021. In early 2021, Brent crude averaged $55-$60 per barrel, up from an average of approximately $40 per barrel in 2020. Despite the current price recovery, uncertainty remains around the current level of oil prices as a result of the on-going effects of COVID-19 and the early stage of global vaccine efforts, as well as the uncertainty surrounding the longevity of the OPEC+ production agreements. Finally, a growing number of the major oil companies, including some of our customers, have signaled increased commitments toward the transition to renewable energy sources. As international majors commit to these renewable energy sources, capital investments could be diverted from longer-term fossil fuel projects, creating even more competition among premium offshore drilling assets.
We believe the convergence of events in 2020 and early 2021 have lengthened an already challenging and slow recovery in our industry. Despite these challenges and demand projections, we believe that oil and gas demand will rebalance and oil and gas will remain an important portion of the world’s energy mix. We expect that the return of stable oil demand and prices coupled with the continued attrition of rigs in the global offshore fleet will bring improved market conditions for our services. Our young and technologically advanced fleet is well positioned to compete as market dynamics improve.
Significant Customers
Offshore contract drilling operations accounted for approximately 94 percent, 95 percent and 96 percent of our operating revenues for the years ended December 31, 2020, 2019 and 2018, respectively. During the three years ended December 31, 2020, we principally conducted our contract drilling operations in Canada, Far East Asia, the Middle East, the North Sea, Oceania, the Black Sea, Africa, South America and the US Gulf of Mexico. Revenues from Exxon Mobil Corporation (“ExxonMobil”), Royal Dutch Shell plc (“Shell”), Equinor ASA (“Equinor”) and Saudi Arabian Oil Company (“Saudi Aramco”) accounted for approximately 26.6 percent, 21.7 percent, 14.3 percent and 13.8 percent, respectively, of our consolidated operating revenues for the year ended December 31, 2020. Revenues from Shell, ExxonMobil, Equinor and Saudi Aramco accounted for approximately 36.5 percent, 13.7 percent, 13.1 percent and 11.9 percent, respectively, of our consolidated operating revenues, which includes the Noble Bully II contract buyout, for the year ended December 31, 2019. Excluding the Noble Bully II contract buyout, revenues from Shell, ExxonMobil, Equinor and Saudi Aramco accounted for approximately 27.1 percent, 15.7 percent, 15.1 percent and 13.6 percent, respectively, of our consolidated operating revenues for the year ended December 31, 2019. Revenues from Shell, Equinor and Saudi Aramco accounted for approximately 38.8 percent, 15.5 percent and 14.5 percent, respectively, of our consolidated operating revenues for the year ended December 31, 2018. No other customer accounted for more than 10 percent of our consolidated operating revenues in 2020, 2019 or 2018.

Human Capital
At December 31, 2020, we had approximately 1,500 employees, excluding approximately 800 persons we engaged through labor contractors or agencies. Approximately 88 percent of our workforce is located offshore. We are not a party to any material collective bargaining agreements, and we consider our employee relations to be satisfactory.
We are fully committed to operating our business with honesty and integrity. Our reputation depends on our directors, officers, employees, and others working on our behalf assuming a personal responsibility for our business conduct. Our compliance program is focused on ensuring adherence with the highest ethical standards and applicable laws and setting the tone for an ethical work environment. Noble’s commitment to a strong compliance culture is fundamental to who we are as a leading offshore drilling contractor. Noble’s Code of Business Conduct and Ethics provides the foundation for our culture and underscores our commitment to our core values of safety, environmental stewardship, honesty and integrity, respect and performance. It also includes our responsibility and commitment to follow all applicable laws as well as our own internal policies, and requires any supplier or third party who works with Noble to comply with similar fundamental principles.
Operating our business in a socially responsible way is integral to who we are. Internally, our employee-focused programs such as recruitment and promotion opportunities, safety and environmental stewardship, and training and continuing education are key to our commitment to the personal and professional growth of our workforce. Externally, our dedication is evidenced by our affiliations and how we contribute to and invest in the communities where we operate.
Recruitment and Promotions. We value a healthy culture of ingenuity and adaptability where everyone has an equal opportunity to thrive. We recognize that an inclusive and diverse workforce is key to the advancement and retention of the best qualified people leading to strong innovation and our continued success. We are committed to a policy of recruitment and promotion based upon job qualifications, performance and merit without discrimination.
Safety and Environmental Stewardship. Noble is committed to delivering excellent health, safety and environmental (“HSE”) performance as part of our business strategy in order to add further value for employees, customers, and shareholders. Safety and environmental stewardship are the cornerstone of who we are, what we stand for and what we do every day to deliver a high-quality operation. All personnel, regardless of job or position onboard our vessels or at any Noble facility, has the authorization and obligation to immediately stop any unsafe act, practice or job that that poses any risk or danger to people or the environment. Noble’s pursuit of exceptional HSE performance begins with our strong corporate culture and by starting SAFE every day: one tour, one task and one person at a time. SAFE is an acronym for the phrase: follow Standards, be Accountable, stay Focused, achieve Excellence. Daily, the crew onboard each rig work together to achieve specific safety and environmental objectives and if all objectives are met, then the day is counted as a SAFE Day. Under our SAFE Day program, in 2020, our rigs achieved the SAFE objectives 98.6% of available days, which is an increase over 2019 performance, and our total recordable incident rate for 2020 decreased 38% from the prior year.
Training and Continuing Education. We place considerable value on the training and development of our employees and maintain a practice of keeping them informed on matters affecting them, as well as on the performance of the Company. Accordingly, we conduct formal and informal meetings with employees, maintain a Company intranet website with matters of interest, issue periodic publications of Company activities and other matters of interest, and offer a variety of in-house training, including through NobleAdvances, our state-of-the-art training facility in Sugar Land, Texas. When travel became a challenge, we developed and enhanced virtual and worksite training courses, some of which are facilitated through our rig-based leadership and are accredited through the International Association of Drilling Contractors.
In consideration of the negative impact of COVID-19 on our employees, customers, suppliers and the communities in which we operate, as well as associated human rights concerns that may exist in the areas in which we operate, we have taken, and will continue to take, incremental measures to monitor, identify and manage risks associated with the COVID-19 pandemic. Throughout the pandemic, we have continued operations in support of essential infrastructure in the energy industry while carefully ensuring worker safety. We have been able to maintain operation of our rigs by implementing several mitigations, such as extending crew schedules to offset travel delays due to limitations or restrictions, implementing quarantine measures in advance of persons boarding our rigs to prevent the spread of COVID-19 on board and enhancing crew health monitoring and response measures to prevent an outbreak on board any of our vessels. We have also continued the operation of our shore-side offices by implementing social distancing programs and implementing staggered rotational schedules for facility employees to reduce the number of persons on site. In addition, we have increased internal contingency planning, protective measures and employee communications and reinforced our employee wellness programs with all offshore and shore-side employees to offset the potential impact on employees both personally and professionally.

Governmental Regulations and Environmental Matters
Political developments and numerous governmental regulations, which may relate directly or indirectly to the contract drilling industry, affect many aspects of our operations. Our contract drilling operations are subject to various laws and regulations in countries in which we operate, including laws and regulations relating to the equipping, supplying and operation of drilling units, environmental protection and related recordkeeping, health and safety of personnel, safety management systems, the reduction of atmospheric emissions that contribute to a cumulative effect on the overall air quality and environment (commonly referred to as greenhouse gases), currency conversions and repatriation, oil and gas exploration and development, taxation of capital equipment, taxation of offshore earnings and earnings of expatriate personnel, employee benefits and use of local employees, content and suppliers by foreign contractors. A number of countries actively regulate and control the ownership of concessions and companies holding concessions, the exportation of oil and gas and other aspects of the oil and gas industries in their countries. In addition, government actions, including initiatives by OPEC, may continue to contribute to oil price volatility. In some areas of the world, this government activity has adversely affected the amount of exploration and development work done by oil and gas companies and influenced their need for offshore drilling services, and likely will continue to do so.
The regulations applicable to our operations include provisions that regulate the discharge of materials into the environment or require remediation of contamination under certain circumstances. Many of the countries in whose waters we operate from time to time regulate the discharge of oil and other contaminants in connection with drilling and marine operations. Failure to comply with these laws and regulations, or failure to obtain or comply with permits, may result in the assessment of administrative, civil and criminal penalties, imposition of remedial requirements and the imposition of injunctions to force future compliance. Although these requirements impact the oil and gas and energy services industries, generally they do not appear to affect us in any material respect that is different, or to any materially greater or lesser extent, than other companies in the energy services industry. However, our business and prospects could be adversely affected by regulatory activity that prohibits or restricts our customers’ exploration and production activities, resulting in reduced demand for our services or imposing environmental protection requirements that result in increased costs to us, our customers or the oil and natural gas industry in general.
The following is a summary of some of the existing laws and regulations that apply in the United States and Europe, which serves as an example of the various laws and regulations to which we are subject. While laws vary widely in each jurisdiction, each of the laws and regulations below addresses regulatory issues similar to those in most of the other jurisdictions in which we operate.
Offshore Regulation and Safety.In response to the Macondo well blowout incident in April 2010, the United States Congress, the US Department of Interior, through the Bureau of Ocean Energy Management (“BOEM”) and the Bureau of Safety and Environmental Enforcement (“BSEE”), and the US Department of Homeland Security, through the United States Coast Guard (“USCG”), have undertaken an aggressive overhaul of the offshore oil and natural gas related regulatory processes, which has significantly impacted oil and gas development and operational requirements in the US Gulf of Mexico. Such actions by the US government has, on occasion, served as a leading indicator for similar regulatory developments or requirements by other countries where, from time to time, new rules, regulations and requirements in the United States and in other countries have been proposed and implemented that materially limit or prohibit, and increase the cost of, offshore drilling and related operations. Other similar regulations impact certain operational requirements on rigs and govern liability for vessel or cargo loss, or damage to life, property, or the marine environment. See Part I, Item 1A, “Risk Factors —Regulatory and Legal Risks—Changes in, compliance with, or our failure to comply with the certain laws and regulations may negatively impact our operations and could have a material adverse effect on our results of operations” and “Risk Factors—Regulatory and Legal Risks— Governmental laws and regulations may add to our costs, result in delays, or limit our drilling activity” for additional information.
Spills and Releases. The US Oil Pollution Act of 1990 (“OPA”), the Comprehensive Environmental Response, Compensation, and Liability Act in the United States (“CERCLA”), and similar regulations, including but not limited to the International Convention for the Prevention of Pollution from Ships (“MARPOL”), adopted by the International Maritime Organization (“IMO”), as enforced in the United States through the domestic implementing law called the Act to Prevent Pollution from Ships, impose certain operational requirements on offshore rigs operating in the United States and govern liability for leaks, spills and blowouts involving pollutants. OPA imposes strict, joint and several liabilities on “responsible parties” for damages, including natural resource damages, resulting from oil spills into or upon navigable waters, adjoining shorelines or in the exclusive economic zone of the United States. A “responsible party” includes the owner or operator of an onshore facility and the lessee or permit holder of the area in which an offshore facility is located. CERCLA and similar state and foreign laws and regulations, impose joint and several liabilities, without regard to fault or the legality of the original act, on certain classes of persons that contributed to the release of a “hazardous substance” into the environment. In the course of our ordinary operations, we may generate waste that may fall within the scope of CERCLA's definition of a “hazardous substance.” However, we have to-date not received any notification that we are, or may be, potentially responsible for cleanup costs under CERCLA.
Regulations under OPA require owners and operators of rigs in United States waters to maintain certain levels of financial responsibility. The failure to comply with OPA’s requirements may subject a responsible party to civil, criminal, or administrative enforcement actions. We are not aware of any action or event that would subject us to liability under OPA, and we believe that compliance with OPA’s financial assurance and other operating requirements will not have a material impact on our operations or financial condition.

Waste Handling. The US Resource Conservation and Recovery Act (“RCRA”), and similar state, local and foreign laws and regulations govern the management of wastes, including the treatment, storage and disposal of hazardous wastes. RCRA imposes stringent operating requirements, and liability for failure to meet such requirements, on a person who is either a “generator” or “transporter” of hazardous waste or an “owner” or “operator” of a hazardous waste treatment, storage or disposal facility. RCRA and many state counterparts specifically exclude from the definition of hazardous waste drilling fluids, produced waters, and other wastes associated with the exploration, development, or production of crude oil and natural gas. As a result, our operations generate minimal quantities of RCRA hazardous wastes. We do not believe the current costs of managing our wastes, as they are presently classified, to be significant. However, any repeal or modification of this or similar exemption in similar state statutes, would increase the volume of hazardous waste we are required to manage and dispose of, and would cause us, as well as our competitors, to incur increased operating expenses with respect to our US operations.
Water Discharges. The US Federal Water Pollution Control Act of 1972, as amended, also known as the “Clean Water Act,” and similar state laws and regulations impose restrictions and controls on the discharge of pollutants into federal and state waters. These laws also regulate the discharge of storm water in process areas. Pursuant to these laws and regulations, we are required to obtain and maintain approvals or permits for the discharge of wastewater and storm water. In addition, the USCG has promulgated requirements for ballast water management as well as supplemental ballast water requirements, which includes limits and, in some cases, water treatment requirements applicable to specific discharge streams, such as deck runoff, bilge water and gray water. Further, in October 2020, the United States Environmental Protection Agency (“EPA”) published proposed national standards of performance for incidental discharges pursuant to the Vessel Incidental Discharge Act. The proposed rule would establish discharge standards for a range of vessels, including mobile offshore drilling units. We do not anticipate that compliance with these laws and regulations will cause a material impact on our operations or financial condition.
Air Emissions. The US Federal Clean Air Act and associated state laws and regulations restrict the emission of air pollutants from many sources, including oil and natural gas operations. New facilities may be required to obtain permits before operations can commence, and existing facilities may be required to obtain additional permits, and incur capital costs, in order to remain in compliance. Federal and state regulatory agencies can impose administrative, civil and criminal penalties for non-compliance with air permits or other requirements of the Clean Air Act and associated state laws and regulations. In general, we believe that compliance with the Clean Air Act and similar state laws and regulations will not have a material impact on our operations or financial condition.
Climate Change.Climate change is an environmental, social and economic challenge facing everyone today. We are committed to continuous improvement and a sustainable energy future, supported by our efforts to protect the environment throughout our operations and safely provide reliable and efficient services to allow access to resources essential for human and economic prosperity. There is increasing attention concerning the issue of climate change and the effect of greenhouse gas (“GHG”) emissions. The EPA regulates the permitting of GHG emissions from stationary sources under the Clean Air Act’s Prevention of Significant Deterioration and Title V permitting programs, which require the use of “best available control technology” for GHG emissions from new and modified major stationary sources, which can sometimes include our rigs. The EPA has also adopted rules requiring the monitoring and reporting of GHG emissions from specified sources in the United States, including, among other things, certain onshore and offshore oil and natural gas production facilities, on an annual basis.
Moreover, in 2005, the Kyoto Protocol to the 1992 United Nations Framework Convention on Climate Change, which establishes a binding set of emission targets for GHGs, became binding on all countries that had ratified it. In 2015, the United Nations (“U.N.”) Climate Change Conference in Paris resulted in the creation of the Paris Agreement. In September 2016, the US deposited its instrument of acceptance of the Paris Agreement, which later entered into force on November 4, 2016. The Paris Agreement requires countries to review and “represent a progression” in their nationally determined contributions, which set emissions reduction goals, every five years beginning in 2020. In November 2019, the US submitted formal notification to the U.N. of its decision to withdraw from the Paris Agreement, which took effect on November 4, 2020. However, in January 2021, shortly after Joseph Biden was sworn into office as the President of the United States, a series of executive orders were issued regarding climate change, which in part led to the US again depositing an instrument of acceptance of the Paris Agreement, which thereafter re-entered into force for the US on February 19, 2021. The terms of the Paris Agreement and the executive orders are expected to result in additional regulations or changes to existing regulations, which could have a material adverse effect on our business in the US and that of our customers. In addition, incentives to conserve energy or use alternative energy sources in many of the countries where we currently operate or may operate in the future, could have a negative impact on our business in those countries and worldwide. See Part I, Item1A, “Risk Factors—Regulatory and Legal Risks— Governmental laws and regulations may add to our costs, result in delays, or limit our drilling activity” for additional information.
Countries in the European Union (“EU”) implement the U.N.’s Kyoto Protocol on GHG emissions through the Emissions Trading System (“ETS”). The ETS program establishes a GHG “cap and trade” system for certain industry sectors, including power generation at some offshore facilities. Total GHG from these sectors is capped, and the cap is reduced over time to achieve GHG reductions from these sectors. In September 2020, the European Commission presented a plan to increase the EU’s GHG reduction target to at least 55% by 2030 in accordance with the European Green Deal. In order to reach this goal, the European Commission has proposed potential revisions and expansions of the EU ETS.
10


In addition, the United Kingdom (“UK”) government implemented its own ETS in January 2021 to replace the UK’s participation in the EU ETS. The UK has also introduced an auction price floor to prevent carbon prices from dropping below a set level during the initial implementation of the UK ETS. The cost of compliance with the UK ETS and the EU ETS can be expected to increase over time. Additional member state climate change legislation may result in potentially material capital expenditures.
We have determined that combustion of ultra-low sulfur fuel oil aboard all of our vessels worldwide (Scope 1) is the Company’s primary source of GHG emissions, which includes carbon dioxide, methane and nitrous oxide. Based upon the emissions calculation factor provided by the original equipment manufacturer for each engine type utilized on our vessels, for the year ended December 31, 2020, our estimated carbon dioxide equivalent (“C02e”) gas emissions were 960,593 tons as compared to 1,063,925 tons for the year ended December 31, 2019. When expressed as an intensity measure of tons of C02e gas emissions per contract day for our vessels worldwide, the intensity measure for December 31, 2020 and 2019 was 174.58 and 156.85, respectively.
The increase of our C02e intensity average from 2019 to 2020 is largely attributed to fewer contracted days in 2020 for several of our vessels that have lower operating energy demands, while our larger vessels that require more energy collectively operated for more contracted days during the same period.
Noble utilizes emission coefficient factors directly from the OEM engine manufacturers carefully calculated per engine type and fuel usage to determine emissions generated from our direct operations throughout the year. While OEM provided coefficients are one method of calculation, there are other relevant industry and regulatory approved standards for calculating GHG production that lead us to a broader understanding of our GHG impact. Each of these methods of calculation vary in assumptions made during the calculation process. By providing these additional calculations such as the Environmental Emissions Monitoring System (EEMS), we feel we are more prepared to compare our emissions data to those relevant industry standards and accurately compare to peer performance with a higher degree of transparency.
Our Scope 1 C02e gas emissions reporting has been prepared with reference to the requirements set out in the UK Companies Act 2006 Regulations 2013, the Environmental Reporting Guidelines (June 2013) issued by the Department for Environment Food & Rural Affairs, the World Resources Institute and World Business Council for Sustainable Development GHG Protocol Corporate Accounting and Reporting Standard Revised and the International Organization for Standardization (“ISO”) 14064-1, “Specification with guidance at the organizational level for quantification and reporting of greenhouse gas emissions and removals (2006).”
Worker Safety. The US Occupational Safety and Health Act (“OSHA”) and other similar laws and regulations govern the protection of the health and safety of employees. The OSHA hazard communication standard, EPA community right-to-know regulations under Title III of CERCLA and similar state statutes require that information be maintained about hazardous materials used or produced in our operations and that this information be provided to employees, state and local governments and citizens. EU member states have also adopted regulations pursuant to EU Directive 2013/30/EU, on the safety of offshore oil and gas operations within the exclusive economic zone (which can extend up to 200 nautical miles from a coast) or the continental shelf. We believe that we are in substantial compliance with OSHA requirements and EU directive 2013/30/EU (as well as the extensive current health and safety regimes implemented in the member states in which we operate), but future developments could require the Company to incur significant costs to comply with the directive's implementation.
International Regulatory Regime.The IMO provides international regulations governing shipping and international maritimetrade. IMO regulations have been widely adopted by U.N. member countries, and in some jurisdictions in which we operate, these regulations have been expanded upon. The requirements contained in the International Management Code for the Safe Operation of Ships and for Pollution Prevention, or ISM Code, promulgated by the IMO, govern much of our drilling operations. Among other requirements, the ISM Code requires the party with operational control of a vessel to develop an extensive safety management systemthat includes, among other things, the adoption of a safety and environmental protection policy setting forth instructions and procedures for operating its vessels safely and describing procedures for responding to emergencies.
The IMO has also adopted and revised MARPOL, including Annex VI to MARPOL, which limits the main air pollutants contained in exhaust gas from ships, including sulfur oxides (“SOx”) and nitrous oxides (“NOx”), prohibits deliberate emissions of ozone depleting substances (“ODS”), regulates shipboard incineration and the emissions of volatile organic compounds (“VOC”) from tankers, sets a progressive reduction globally in emissions of SOx, NOx and particulate matter, introduces emission control areas (“ECAs”) to reduce emissions of those air pollutants further in designated sea areas, and effective from January 1, 2020, reduces the global sulfur limit in fuel oil from the current 3.50% to 0.50% m/m (mass by mass) sulfur content. Prior to January 1, 2020, our rigs were operating and continue to operate with low sulfur fuel oil at or below the global limits of 0.50%.
The IMO has also negotiated international conventions that impose liability for oil pollution in international waters and the territorial waters of the signatory to such conventions such as the Ballast Water Management Convention, (the “BWM Convention”) and the International Convention for Civil Liability for Bunker Oil Pollution Damage of 2001 (the “Bunker Convention”). The BWM Convention's implementing regulations call for a phased introduction of mandatory ballast of water exchange requirements, to be replaced in time with a requirement for
11


mandatory ballast water treatment. The Bunker Convention provides a liability, compensation and compulsory insurance system for the victims of oil pollution damage caused by spills of bunker oil. We believe that all of our drilling rigs are currently compliant in all material respects with these regulations. However, the IMO continues to review and introduce new regulations. It is impossible to predict what additional regulations, if any, may be passed by the IMO and what effect, if any, such regulation may have on our operations.
Insurance and Indemnification Matters
Our corporate headquartersoperations are subject to many hazards inherent in the drilling business, including blowouts, fires, collisions, groundings, punch-throughs, and damage or loss from adverse weather and sea conditions. These hazards could cause personal injury or loss of life, loss of revenues, pollution and other environmental damage, damage to or destruction of property and equipment and oil and natural gas producing formations, and could result in claims by employees, customers or third parties and fines and penalties.
Our drilling contracts provide for varying levels of indemnification from our customers and in most cases also require us to indemnify our customers for certain losses. Under our drilling contracts, liability with respect to personnel and property is locatedtypically assigned on a “knock-for-knock” basis, which means that we and our customers assume liability for our respective personnel and property, generally irrespective of the fault or negligence of the party indemnified. In addition, our customers may indemnify us in London, England.certain instances for damage to our down-hole equipment and, in some cases, our subsea equipment. Also, we generally obtain a mutual waiver of consequential losses in our drilling contracts.
Our customers typically assume responsibility for and indemnify us from loss or liability resulting from pollution or contamination, including third-party damages and clean-up and removal, arising from operations under the contract and originating below the surface of the water. We are generally responsible for pollution originating above the surface of the water and emanating from our drilling units. Additionally, our customers typically indemnify us for liabilities incurred as a result of a blow-out or cratering of the well and underground reservoir loss or damage. In the current market, we are under increasing pressure to accept exceptions to the above-described allocations of risk and, as a result, take on more risk. In such cases where we agree, we generally limit the exposure with a monetary cap and other restrictions.
In addition to the contractual indemnities described above, we also carry Protection and Indemnity (“P&I”) insurance, which is a comprehensive general liability insurance program covering liability resulting from offshore operations. Our P&I insurance includes coverage for liability resulting from personal injury or death of third parties and our offshore employees, third-party property damage, pollution, spill clean-up and containment and removal of wrecks or debris. Our P&I insurance program is renewed in April of each year and currently has a standard deductible of $10.0 million per occurrence, with maximum liability coverage of $750.0 million. We also carry hull and machinery insurance that protects us against physical loss or damage to our drilling rigs, subject to a deductible that is currently $5.0 million.
Our insurance policies and contractual rights to indemnity may not adequately cover our losses and liabilities in all cases. For additional information, please read “We may have difficulty obtaining or maintaining insurance in the future and our insurance coverage and contractual indemnity rights may not protect us against all the risks and hazards we face” included in Part I, Item 1A, “Risk Factors” of this Annual Report on Form 10-K.
The above description of our insurance program and the indemnification provisions of our drilling contracts is only a summary as of the time of preparation of this report, and is general in nature. Our insurance program and the terms of our drilling contracts may change in the future. In addition, the indemnification provisions of our drilling contracts may be subject to differing interpretations, and enforcement of those provisions may be limited by public policy and other considerations.

For a more complete discussion of the material risks facing our business, see below.
Risks Related to Our Emergence from Bankruptcy
We recently emerged from bankruptcy, which may adversely affect our business and relationships.
It is possible that our having filed for bankruptcy and our recent emergence from the Chapter 11 Cases may adversely affect our business and relationships with our vendors, suppliers, service providers, customers, employees and other third parties. Many risks exist as a result of the Chapter 11 Cases and our emergence, including the following:
13


we may have difficulty obtaining acceptable and sufficient financing to execute our business plan;
key suppliers, vendors and customers, may among other things, renegotiate the terms of our agreements, attempt to terminate their relationship with us or require financial assurances from us;
our ability to renew existing contracts and obtain new contracts on reasonably acceptable terms and conditions may be adversely affected;
our ability to attract, motivate and retain key employees and executives may be adversely affected; and
competitors may take business away from us, and our ability to compete for new business and attract and retain customers may be negatively impacted.
The occurrence of one or more of these events could have a material and adverse effect on our operations, financial condition and reputation. We cannot assure you that having been subject to bankruptcy protection will not adversely affect our operations in the future.
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, we prepared projected financial information to demonstrate to the Bankruptcy Court the feasibility of the Plan 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 reviewed the projections 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.
Our historical financial information will not be indicative of future financial performance as a result of the implementation of the Plan and the transactions contemplated thereby, as well as our adoption of fresh start accounting following emergence.
Our capital structure was significantly impacted by the Plan. Under fresh start accounting rules that became applicable to us upon the Effective Date, assets and liabilities will be adjusted to fair values and our accumulated deficit will be reset to zero. Accordingly, because fresh start accounting rules apply, our financial condition and results of operations following emergence from the Chapter 11 Cases will not be comparable to the financial condition and results of operations reflected in our historical financial statements from before February 5, 2021.
Legacy Noble’s ordinary shares were cancelled upon our emergence from bankruptcy.
Upon our emergence from the Chapter 11 Cases, Legacy Noble’s ordinary shares were cancelled and we issued the New Shares. We intend to apply for a listing of the New Shares on a national securities exchange. However, we can provide no assurance when we will apply for listing of the New Shares, whether the New Shares will be approved for listing, whether an active trading market will develop for the New Shares or as to the liquidity of such trading market for the New Shares.
The warrants we issued pursuant to the Plan are exercisable for New Shares, and the exercise of such equity instruments would have a dilutive effect to shareholders of the Company.
On the Effective Date and pursuant to the Plan, we issued 8,333,081 Tranche 1 Warrants and 8,333,081 Tranche 2 Warrants to the holders of Legacy Notes (as defined herein) and 2,777,698 Tranche 3 Warrants to the holders of Legacy Noble’s ordinary shares outstanding prior to the Effective Date. The warrants are exercisable for one New Share per warrant at initial exercise price of $19.27 per Tranche 1 Warrant, $23.13 per Tranche 2 Warrant and $124.40 per Tranche 3 Warrant, in each case as may be adjusted from time to time pursuant to the applicable warrant agreements. The Tranche 1 Warrants and the Tranche 2 Warrants are exercisable until 5:00 p.m., Eastern time, on February 4, 2028 and the Tranche 3 Warrants are exercisable until 5:00 p.m., Eastern time, on February 4, 2026. The Tranche 1 and Tranche 2 Warrants have Black-Scholes protections. The exercise of these warrants into New Shares would have a dilutive effect to the holdings of our existing shareholders.

Risks Related to Our Business and Operations
Public health issues, including epidemics or pandemics such as COVID-19 have resulted in, and may in the future cause, significant adverse consequences for our business and financial position.
Public health issues, such as the COVID-19 pandemic, our mitigation efforts necessitated by COVID-19, and the effect from the actual and potential disruption of operations of our business partners, suppliers and customers, have had, and may in the future have, a material negative impact on our business and results of operations. In addition, if new strains of COVID-19 develop or sufficient amounts of approved vaccines or new vaccines do not become available, are not widely administered for a significant period of time, or otherwise prove ineffective, the negative impact of COVID-19 on the global economy, and, in turn, on our business and results of operations, could be material.
In response to COVID-19, governmental authorities around the world took various actions over time to mitigate the spread of COVID-19, such as imposing mandatory closures of non-essential business facilities, seeking voluntary closures of certain businesses, and imposing restrictions on, or advisories with respect to, travel, business operations and public gatherings or interactions. In addition, individuals and entities implemented measures in response to the pandemic and the governmental actions, as well as made changes to personal behaviors, such as requiring employees to work remotely, suspending non-essential travel worldwide for employees, discouraging or canceling employee attendance at in-person work-related meetings, and social distancing and isolating from others.
We have taken and will continue to take precautionary measures intended to mitigate the risk to our business, employees, customers, suppliers and the communities in which we operate. Our operational employees have been, and currently are, able to work on site and on our rigs, due in part to various precautionary measures with little or no material negative impact on the business and results of operations, such as requiring individuals to verify they have not experienced any COVID-19 related symptoms, or been in close contact with someone showing such symptoms or having recently tested positive for COVID-19, before they are permitted to travel to the work site or rig; quarantining any operational employees on a rig who have shown signs of COVID-19 (regardless of whether such employee has been confirmed to be infected); and imposing social distancing requirements in various areas of the rig, such as in the dining hall, work and meeting spaces, and sleeping quarters. Other precautionary measures that have contributed to our ability to continue operations have nonetheless had a material negative impact on the business and results of operations, such as requiring individuals to isolate in a designated facility or repurposed hotel for up to 14 days and test negative for COVID-19 prior to being permitted to travel to our rigs, which has resulted in an increase in the cost of operations. We are also actively assessing and planning for various operational contingencies; however, we cannot guarantee that any actions taken by us, including the precautionary measures noted above, will be effective in preventing an interruption of operations from an outbreak of COVID-19 or absence due to COVID-19 infection resulting in the vacancy of essential positions on one or more of our rigs. To the extent there is an outbreak of COVID-19 or vacancy of essential positions on one or more of our rigs, we may have to temporarily shut down operations thereof, which could result in significant downtime and have significant adverse consequences for our business and results of operations. In addition, most of our non-operational employees are now working remotely, which increases various logistical challenges, inefficiencies and operational risks. For instance, working remotely may increase the risk of security breaches or other cyber-incidents or attacks, loss of data, fraud and other disruptions as a consequence of more employees accessing sensitive and critical information from remote locations via network infrastructure and internet services not arranged, established or secured by the Company.
Governmental authorities have implemented and continue to develop policies with the goal of re-opening various sectors of the economy. However, certain jurisdictions have returned, or may in the future return, to restrictions based upon increases in new COVID-19 cases. The COVID-19 pandemic may continue unabated or worsen during the upcoming months, which may cause governmental authorities to implement restrictions on businesses and society, resulting in the re-opening of the economy being further curtailed. In complying with travel restrictions and mandatory quarantine measures imposed by governmental authorities and navigating surges in COVID-19 cases in various jurisdictions, we have experienced, and may continue to experience, increased difficulties, delays and expenses in moving our personnel to and from our operating locations. We have been unable, and may in the future be unable, to pass along these increased expenses to our customers. Additionally, disruptions to the ability of our suppliers, manufacturers and service providers to supply labor, parts, equipment or services in the jurisdictions in which we operate, whether as a result of government actions, labor shortages, travel restrictions, or the inability to source labor, parts or equipment from affected locations or other effects related to COVID-19, have increased our operating costs, increased the risk of rig downtime and negatively impacted our ability to meet our commitments to customers and may continue to do so in the future.
These conditions have had significant adverse consequences for the financial condition of many of our customers and resulted in, and may in the future result in, reductions to their drilling and production expenditures and delays or cancellations of projects, thereby decreasing demand for our services. We have experienced customers seeking price reductions for our services, payment deferrals and termination of our contracts; customers seeking to not perform under our contracts based on a force majeure claim; and customers that are unable or unwilling to timely pay outstanding receivables owed to us, all of which present liquidity challenges for us. In addition, we have experienced, and may in the future experience, pressure to reduce dayrates on existing contracts and idle or suspend existing operations. Any early termination payment made in connection with an early contract termination may not fully compensate us for the loss of the contract or may result in a negative
15


impact to our projected future earnings due to the accounting treatment of such a termination payment under applicable accounting requirements. Accordingly, the actual amount of revenues earned may be substantially lower than the backlog reported.
The factors described above, including the ultimate duration and scope of the COVID-19 pandemic (including any potential future outbreaks and the success of vaccination programs), the impact on customers, suppliers, manufacturers and service providers, the timing to return to normal economic conditions, the impact on our operations, the demand for our services, and any permanent behavioral changes that the pandemic may cause, have had, and may continue to have, a material negative impact on our business, results of operations and financial condition, have previously contributed to our ability to continue as a going concern, and could in the future raise substantial doubt about our ability to continue as a going concern. We cannot predict when this negative impact will end, or whether it may worsen.
Our business and results of operations have been materially and negatively impacted and our market value has substantially declined due to depressed market conditions which are the result of, in part, the dramatic drop in the oil price, the development of additional onshore oil and gas resources and the oversupply of offshore drilling rigs.
Crude oil prices have been in a steep decline since late 2014 and dropped to as low as approximately $30 per barrel in January 2016. Oil prices have partially recovered to a price of approximately $68 per barrel on March 10, 2021, but have been volatile and have not recovered to 2014 levels. As a result of the oil price environment prior to the significant drop in 2014, the offshore drilling business flourished with high utilization and high dayrates, and a large number of offshore drilling rigs were constructed to take advantage of the market. Also, many in our industry extended the lives of older rigs rather than retiring these rigs. These factors have led to a significant oversupply of drilling rigs while our customers have greatly reduced their planned offshore exploration and development spending in response to the depressed price of oil.
During the same period, onshore crude oil production in the United States rose sharply. While the cost of production onshore varies, in some cases it may be less than the cost of production in offshore fields where our rigs are designed to operate, especially deepwater fields. Additionally, onshore production is perceived as yielding more consistent results and posing lower regulatory risk than offshore production. This increase in onshore US production has had a negative impact on the price of oil and the demand for our services. Further, given the reduced oil price and often the lower operating costs onshore, many of our customers have allocated more of their capital budgets to onshore exploration activities than offshore exploration activities, particularly deepwater exploration activities, which has also led to a decrease in the demand for offshore drilling services since 2014.
These factors have affected market conditions and led to a material decline in the demand for our services since 2014, the dayrates we are paid by our customers and the level of utilization of our drilling rigs. These poor market conditions, which may continue into the foreseeable future, in turn, have led to a material deterioration in our results of operations. There can be no assurance as to if, when or to what extent the current depressed market conditions, and our business, results of operations or enterprise value, will improve. Further, even if the price of oil and gas were to increase dramatically, we cannot assure you that there would be any increase in demand for our services.
Our business depends on the level of activity in the oil and gas industry. Adverse developments affecting the industry, including a decline in the price of oil or gas, reduced demand for oil and gas products and increased regulation of drilling and production, could have a material adverse effect on our business, financial condition and results of operations.
Demand for drilling services depends on a variety of economic and political factors and the level of activity in offshore oil and gas exploration and development and production markets worldwide. As noted above, the price of oil and gas, and market expectations of potential changes in the price, significantly affect this level of activity, as well as dayrates that we can charge customers for our services. However, higher prices do not necessarily translate into increased drilling activity because our clients take into account a number of considerations when they decide to invest in offshore oil and gas resources, including expectations regarding future commodity prices. The price of oil and gas and the level of activity in offshore oil and gas exploration and development are extremely volatile and are affected by numerous factors beyond our control, including:
the cost of exploring for, developing, producing and delivering oil and gas;
the ability of OPEC to set and maintain officesproduction levels and pricing;
expectations regarding future energy prices;
increased supply of oil and gas resulting from onshore hydraulic fracturing activity and shale development;
the relative cost of offshore oil and gas exploration versus onshore oil and gas production;
worldwide production and demand for oil and gas (including the over-supply of oil and gas as a result of the COVID-19 pandemic and actions by OPEC+ members), which are impacted by changes in the rate of economic growth in the global economy;
potential acceleration in the development, and the price and availability, of alternative fuels or energy sources;
the level of production in non-OPEC countries;
worldwide financial instability or recessions;
regulatory restrictions or any moratorium on offshore drilling;
the discovery rate of new oil and gas reserves either onshore or offshore;
16


the rate of decline of existing and new oil and gas reserves;
available pipeline and other oil and gas transportation capacity;
oil refining capacity;
the ability of oil and gas companies to raise capital;
limitations on liquidity and available credit;
advances in exploration, development and production technology either onshore or offshore;
technical advances affecting energy consumption, including the displacement of hydrocarbons through increasing transportation fuel efficiencies;
merger and divestiture activity among oil and gas producers;
the availability of, and access to, suitable locations from which our customers can produce hydrocarbons;
adverse weather conditions, including hurricanes, typhoons, cyclones, winter storms and rough seas, the frequency and severity of which may be increased due to climate change;
the occurrence or threat of epidemic or pandemic diseases or any governmental response to such occurrence or threat;
tax laws, regulations and policies;
laws and regulations related to environmental matters, including those addressing alternative energy sources, the phase-out of fossil fuel vehicles and the risks of global climate change;
the political environment of oil-producing regions, including uncertainty or instability resulting from civil disorder, an outbreak or escalation of armed hostilities or acts of war or terrorism; and
the laws and regulations of governments regarding exploration and development of their oil and gas reserves or speculation regarding future laws or regulations.
Adverse developments affecting the industry as a result of one or more of these factors, including any further decline in the price of oil and gas from their current levels or the failure of the price of oil and gas to recover to a level that encourages our clients to expand their capital spending, the inability of our customers to access capital on economically advantageous terms, including as a result of the increasing focus on climate change by investors, a global recession, reduced demand for oil and gas products, increased supply due to the development of new onshore drilling and production technologies, and increased regulation of drilling and production, particularly if several developments were to occur in a short period of time, would have a material adverse effect on our business, financial condition and results of operations. The current level of oil and gas prices has had a material adverse effect on demand for our services since 2014 and is expected to continue to have a material adverse effect on our business and results of operations.
The offshore contract drilling industry is a highly competitive and cyclical business with intense price competition. We have competitors who are larger and have more financial resources than us. If we are unable to compete successfully, our profitability may be materially reduced.
The offshore contract drilling industry is a highly competitive and cyclical business characterized by high capital and operating costs and evolving capability of newer rigs. Drilling contracts are traditionally awarded on a competitive bid basis. Price competition, rig availability, location and rig suitability and technical specifications are the primary factors in determining which rig is qualified for a job, and additional factors are considered when determining which contractor is awarded a job, including experience of the workforce, efficiency, safety performance record, condition of equipment, operating integrity, reputation, industry standing and client relations. Our future success and profitability will partly depend upon our ability to keep pace with our customers’ demands with respect to these factors. In the past several years, the pace of consolidation in our industry has increased, leading to the creation of a number of larger and financially stronger competitors. If we are unable, or our customers believe that we are unable, to compete with the scale and financial strength of these larger competitors, it could harm our competitiveness and our ability to secure new drilling contracts. Moreover, certain of our competitors have engaged, or may in the future engage, in bankruptcy proceedings, debt refinancing transactions, management changes or other strategic initiatives in an attempt to reduce operating costs to maintain a position in the market, which could result in such competitors emerging with stronger or healthier balance sheets and, in turn, an improved ability to compete with us in the future. Further, if current competitors, or new market entrants, implement new technical capabilities, services or standards that are more attractive to our customers or price their product offerings more competitively, it could have a material adverse effect on our business, financial condition and results of operations.
In addition to intense competition, our industry has historically been cyclical. The offshore contract drilling industry is currently in a period characterized by low demand for drilling services and excess rig supply. Periods of low demand or excess rig supply intensify the competition in the industry and have resulted in, and are expected to continue to result in, many of our rigs earning substantially lower dayrates or being idle for long periods of time. We cannot provide you with any assurances as to when such period will end, and when there will be higher demand for contract drilling services or a meaningful reduction in the number of drilling rigs.
17


The over-supply of offshore rigs continues to contribute to depressed dayrates and demand for our rigs, which may remain unchanged for some time and, therefore, is expected to further adversely impact our revenues and profitability.
Prior to the current downturn, we experienced an extended period of high utilization and high dayrates, and industry participants materially increased the supply of drilling rigs by building new drilling rigs, including some that have not yet entered service. This increase in supply, combined with the decrease in demand for drilling rigs resulting from the substantial decline in the price of oil that began in 2014, has resulted in an oversupply of drilling rigs, which has contributed to the decline in utilization and dayrates.
We are currently experiencing competition from newbuild rigs that have either already entered the market or are available to enter the market. The entry of these rigs into the market has resulted in lower dayrates for both newbuilds and existing rigs rolling off their current contracts. Lower utilization and dayrates have adversely affected our revenues and profitability and may continue to do so for some time in the future. In addition, our competitors may relocate rigs to geographic markets in which we operate, which could exacerbate excess rig supply and result in lower dayrates and utilization in those markets. To the extent that the drilling rigs currently under construction or on order do not have contracts upon their completion, there may be increased price competition as such vessels become operational, which could lead to a further reduction in dayrates and in utilization, and we may be required to idle additional drilling rigs. Rig operators may take lower dayrates and shorter contract durations on older rigs to keep their rigs operational and avoid scrapping or retiring them. As a result, our business, financial condition and results of operations would be materially adversely affected.
We may not be able to renew or replace expiring contracts, and our customers may terminate or seek to renegotiate or repudiate our drilling contracts or may have financial difficulties that prevent them from meeting their obligations under our drilling contracts.
Since the market downturn began at the end of 2014, the new customer contracts we have entered into have generally had less favorable terms, including dayrates, than contracts entered into prior to the downturn. In addition, for some of our older rigs we were unable to find any replacement contracts. Our ability to renew contracts that expire or obtain new contracts and the terms of any such contracts will depend on market conditions and our customers' expectations and assumptions of future oil prices and other factors.
Our customers may generally terminate our drilling contracts if a drilling rig is destroyed or lost or if we have to suspend drilling operations for a specified period of time as a result of a breakdown of major equipment or, in some cases, due to other events beyond the control of either party. In the case of nonperformance and under certain other conditions, our drilling contracts generally allow our customers to terminate without any payment to us. The terms of some of our drilling contracts permit the customer to terminate the contract after a specified notice period by tendering contractually specified termination amounts and, in some cases, without any payment. These termination payments, if any, may not fully compensate us for the loss of a contract. The early termination of a contract may result in a rig being idle for an extended period of time and a reduction in our contract backlog and associated revenue, which could have a material adverse effect on our business, financial condition and results of operations. Moreover, if any of our long-term contracts were to be terminated early, such termination could affect our future earnings flow and could have material adverse effect on our future financial condition and results of operations, even if we were to receive the contractually specified termination amount.
In addition, during periods of depressed market conditions, such as the one we are currently experiencing, we are subject to an increased risk of our customers seeking to renegotiate or repudiate their contracts. The ability of our customers to perform their obligations under drilling contracts with us may also be adversely affected by the financial condition of the customer, restricted credit markets, economic downturns and industry downturns. We may elect to renegotiate the rates we receive under our drilling contracts downward if we determine that to be a reasonable business solution. If our customers cancel or are unable to perform their obligations under their drilling contracts, including their payment obligations, and we are unable to secure new contracts on a timely basis on substantially similar terms or if we elect to renegotiate our drilling contracts and accept terms that are less favorable to us, it could have a material adverse effect on our business, financial condition and results of operations.
Our current backlog of contract drilling revenue may not be ultimately realized.
Generally, contract backlog only includes future revenues under firm commitments; however, from time to time, we may report anticipated commitments under letters of intent or award for which definitive agreements have not yet been, but are expected to be, executed. We may not be able to perform under these contracts as a result of operational or other breaches or due to events beyond our control, and we may not be able to ultimately execute a definitive agreement in cases where one does not currently exist. Moreover, we can provide no assurance that our customers will be able to or willing to fulfill their contractual commitments to us or that they will not seek to renegotiate or repudiate their contracts, especially during the current industry downturn. The terms of some of our drilling contracts permit the customer to terminate the contract after specified notice periods by tendering contractually specified termination amounts and, in certain cases, without any payment. In estimating backlog, we make certain assumptions about applicable dayrates for our longer-term contracts with dayrate adjustment mechanisms (like certain of our contracts with Shell). We cannot assure you that actual results will mirror these assumptions. Our inability to perform under our contractual obligations or to execute definitive agreements, our customers’ inability or unwillingness to fulfill their contractual commitments to us, including as a result of contract repudiations or our decision to accept less favorable terms on our drilling
18


contracts, or the failure of actual results to reflect the assumptions we use to estimate backlog for certain contracts, may have a material adverse effect on our business, financial condition and results of operations.
We are substantially dependent on several of our customers, including Equinor, ExxonMobil, Saudi Aramco and Shell, and the loss of any of these customers would have a material adverse effect on our financial condition and results of operations.
Any concentration of customers increases the risks associated with any possible termination or nonperformance of drilling contracts, failure to renew contracts or award new contracts or reduction of their drilling programs. Equinor, ExxonMobil, Saudi Aramco and Shell accounted for approximately 14.3 percent, 26.6 percent, 13.8 percent and 21.7 percent, respectively, of our consolidated operating revenues and approximately 3.6 percent, 44.2 percent, 17.0 percent and 26.3 percent, respectively, of our backlog for the year ended December 31, 2020. This concentration of customers increases the risks associated with any possible termination or nonperformance of contracts, in addition to our exposure to credit risk. If any of these customers were to terminate or fail to perform their obligations under their contracts and we were not able to find other customers for the affected drilling units promptly, our financial condition and results of operations could be materially adversely affected.
Our business involves numerous operating hazards.
Our operations are subject to many hazards inherent in the drilling business, including:
well blowouts;
fires;
collisions or groundings of offshore equipment and helicopter accidents;
punch-throughs;
mechanical or technological failures;
failure of our employees or third-party contractors to comply with our internal environmental, health and safety guidelines;
pipe or cement failures and casing collapses, which could release oil, gas or drilling fluids;
geological formations with abnormal pressures;
loop currents or eddies;
failure of critical equipment;
toxic gas emanating from the well;
spillage handling and disposing of materials; and
adverse weather conditions, including hurricanes, typhoons, tsunamis, cyclones, winter storms and rough seas, the frequency and severity of which may be increased due to climate change.
These hazards could cause personal injury or loss of life, suspend drilling operations, result in regulatory investigation or penalties, seriously damage or destroy property and equipment, result in claims by employees, customers or third parties, cause environmental damage and cause substantial damage to oil and gas producing formations or facilities. Operations also may be suspended because of machinery breakdowns, abnormal drilling conditions, and failure of subcontractors to perform or supply goods or services or personnel shortages. The occurrence of any of the hazards we face could have a material adverse effect on our business, financial condition and results of operations.
We are exposed to risks relating to operations in international locations.
We operate in various regions throughout the world that may expose us to political and other uncertainties, including risks of:
seizure, nationalization or expropriation of property or equipment;
monetary policies, government credit rating downgrades and potential defaults, and foreign currency fluctuations and devaluations;
limitations on the ability to repatriate income or capital;
complications associated with repairing and replacing equipment in remote locations;
repudiation, nullification, modification or renegotiation of contracts;
limitations on insurance coverage, such as war risk coverage, in certain areas;
import-export quotas, wage and price controls and imposition of trade barriers;
delays in implementing private commercial arrangements as a result of government oversight;
compliance with and changes in taxation rules or policies;
compliance with and changes in various jurisdictional regulatory or financial requirements, including rig flagging and local ownership requirements;
other forms of government regulation and economic conditions that are beyond our control and that create operational uncertainty;
governmental corruption;
19


the occurrence or threat of epidemic or pandemic diseases or any government response to such occurrence or threat;
piracy; and
terrorist acts, war, revolution and civil disturbances.
Further, we operate or have operated in certain less-developed countries with legal systems that are not as mature or predictable as those in more developed countries, which can lead to greater uncertainty in legal matters and proceedings. Examples of challenges of operating in these countries include:
procedural requirements for temporary import permits, which may be difficult to obtain; and
the effect of certain temporary import permit regimes, where the duration of the permit does not coincide with the general term of the drilling contract.
Our ability to do business in a number of jurisdictions is subject to maintaining required licenses and permits and complying with applicable laws and regulations. For example, all of our drilling units are subject to regulatory requirements of the flag state where the drilling unit is registered. The flag state requirements are international maritime requirements and, in some cases, further interpolated by the flag state itself. In addition, each of our drilling units must be “classed” by a classification society, signifying that such drilling rig has been built and maintained in accordance with the rules of the classification society and complies with applicable rules and regulations of the flag state. If any drilling unit loses its flag, does not maintain its class or fails any periodical survey or special survey, the drilling unit will be unable to carry on operations and will be unemployable and uninsurable.
Jurisdictions where we operate may attempt to impose requirements that our drilling units operating in such a jurisdiction have some local ownership or be registered under the flag of that jurisdiction, or both. If our debt agreements do not permit us to change the flag of a rig to a certain jurisdiction or register a rig under the flag of that jurisdiction (and consequently comply with local ownership requirements), and if we are otherwise unable to successfully object to registration, we may no longer be able to operate in that country. Any such inability to carry on operations in jurisdictions where we operate or desire to operate, or our failure to comply with any other laws and regulations of the countries where we operate, could have a material adverse effect on our results of operations.
In addition, OPEC initiatives, as well as other governmental actions, may continue to cause oil price volatility. In some areas of the world, this governmental activity has adversely affected the amount of exploration and development work done by major oil companies, which may continue. In addition, some governments favor or effectively require the awarding of drilling contracts to local contractors, require use of a local agent, require partial local ownership or require foreign contractors to employ citizens of, or purchase supplies from, a particular jurisdiction. These practices may adversely affect our ability to compete and our results of operations.
In June 2016, the UK held a referendum in which voters approved an exit from the EU (“Brexit”). The UK exited the EU on January 31, 2020, consistent with the terms of the EU-UK Withdrawal Agreement, with a transition period that ended on December 31, 2020. On January 1, 2021, the UK left the EU Single Market and Customs Union as well as all EU policies and international agreements. As a result, the free movement of persons, goods, services and capital between the UK and the EU ended, and the EU and the UK formed two separate markets and two distinct regulatory and legal spaces. On December 24, 2020, the European Commission reached a trade agreement with the UK on the terms of its future cooperation with the EU. The trade agreement offers UK and EU companies preferential access to each other’s markets, ensuring imported goods will be free of tariffs and quotas (subject to rules of origin requirements). Uncertainty exists regarding the ultimate impact of this trade agreement, as well as the extent of possible financial, trade, regulatory and legal implications of Brexit. Brexit also contributes to global political and economic uncertainty, which may cause, among other consequences, volatility in exchange rates and interest rates, and changes in regulations. The Company provides contract drilling services to the international oil and gas industry and our fleet operates globally across multiple locations. Based on our global operating model and the versatility and marketability of our fleet, we do not expect the impact of Brexit to be significant to the Company.
Operating and maintenance costs of our rigs may be significant and may not correspond to revenue earned.
Our operating expenses and maintenance costs depend on a variety of factors including: crew costs, costs of provisions, equipment, insurance, maintenance and repairs, and shipyard costs, many of which are beyond our control. Our total operating costs are generally related to the number of drilling rigs in operation and the cost level in each country or region where such drilling rigs are located. Equipment maintenance costs fluctuate depending upon the type of activity that the drilling rig is performing and the age and condition of the equipment. Operating and maintenance costs will not necessarily fluctuate in proportion to changes in operating revenues. While operating revenues may fluctuate as a function of changes in dayrate, costs for operating a rig may not be proportional to the dayrate received and may vary based on a variety of factors, including the scope and length of required rig preparations and the duration of the contractual period over which such expenditures are amortized. Any investments in our rigs may not result in an increased dayrate for or income from such rigs. A disproportionate amount of operating and maintenance costs in comparison to dayrates could have a material adverse effect on our business, financial condition and results of operations.
20


Drilling contracts with national oil companies may expose us to greater risks than we normally assume in drilling contracts with non-governmental clients.
Contracts with national oil companies 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 and other claims for damages (including consequential damages) and personal injury related to our operations, or the risk that the contract may be terminated by our client without cause on short-term notice, contractually or by governmental action, under certain conditions that may not provide us an early termination payment, collection risks and political risks. In addition, our ability to resolve disputes or enforce contractual provisions may be negatively impacted with these contracts. 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 rigs contracted to national oil companies with commensurate additional contractual risks.
Operational interruptions or maintenance or repair work may cause our customers to suspend or reduce payment of dayrates until operation of the respective drilling rig is resumed, which may lead to loss of revenue or termination or renegotiation of the drilling contract.
If our drilling rigs are idle for reasons that are not related to the ability of the rig to operate, our customers are entitled to pay a waiting, or standby, rate that is lower than the full operational rate. In addition, if our drilling rigs are taken out of service for maintenance and repair for a period of time that exceeds the scheduled maintenance periods set forth in our drilling contracts, we will not be entitled to payment of dayrates until the rig is able to work. Several factors could cause operational interruptions, including:
breakdowns of equipment and other unforeseen engineering problems;
work stoppages, including labor strikes;
shortages of material and skilled labor;
delays in repairs by suppliers;
surveys by government and maritime authorities;
periodic classification surveys;
inability to obtain permits;
severe weather, strong ocean currents or harsh operating conditions;
force majeure events; and
the occurrence or threat of epidemic or pandemic diseases or any government response to such occurrence or threat.
If the interruption of operations exceeds a determined period due to an event of force majeure, our customers have the right to pay a rate that is significantly lower than the waiting rate for a period of time and, thereafter, may terminate the drilling contracts related to the subject rig. Suspension of drilling contract payments, prolonged payment of reduced rates or termination of any drilling contract as a result of an interruption of operations as described herein could materially adversely affect our business, financial condition and results of operations.
We may have difficulty obtaining or maintaining insurance in the future and our insurance coverage and contractual indemnity rights may not protect us against all the risks and hazards we face.
We do not procure insurance coverage for all of the potential risks and hazards we may face. Furthermore, no assurance can be given that we will be able to obtain insurance against all of the risks and hazards we face or that we will be able to obtain or maintain adequate insurance at rates and with deductibles or retention amounts that we consider commercially reasonable. In addition, our insurance carriers may interpret our insurance policies such that they do not cover losses for which we make claims.
Although we maintain insurance in the geographic areas in which we operate, pollution, reservoir damage and environmental risks generally are not fully insurable. Our insurance policies may not adequately cover our losses or may have exclusions of coverage for some losses. We do not have insurance coverage or for all risks, including loss of hire insurance on most of the rigs in our fleet. Uninsured exposures may include expatriate activities prohibited by US laws and regulations, radiation hazards, cyber risks, certain loss or damage to property onboard our rigs and losses relating to shore-based terrorist acts or strikes. In addition, our insurance may not cover losses associated with pandemics such as the COVID-19 pandemic. Furthermore, the damage sustained to offshore oil and gas assets in the United States as a result of hurricanes has negatively impacted certain aspects of the energy insurance market, resulting in more restrictive and expensive coverage for US named windstorm perils due to the price or lack of availability of coverage. Accordingly, we have in the past self-insured the rigs in the US Gulf of Mexico for named windstorm perils. We currently have US windstorm coverage for most of our US fleet subject to certain limits, but will continue to monitor the insurance market conditions in the future and may decide not to, or be unable to, purchase named windstorm coverage for some or all of the rigs operating in the US Gulf of Mexico.
Under our drilling contracts, liability with respect to personnel and property is customarily assigned on a “knock-for-knock” basis, which means that we and our customers assume liability for our respective personnel and property, irrespective of the fault or negligence of the party indemnified. Although our drilling contracts generally provide for indemnification from our customers for certain liabilities, including liabilities resulting from pollution or contamination originating below the surface of the water, enforcement of these contractual rights to indemnity may be limited by public policy and other considerations and, in any event, may not adequately cover our losses from such incidents. There can also be no assurance that those parties with contractual obligations to indemnify us will necessarily be in a financial position to do
21


so. During depressed market periods such as the one in which we currently operate, the contractual indemnity provisions we are able to negotiate in our drilling contracts may require us to assume more risk than we would during normal market periods.
If a significant accident or other event occurs and is not fully covered by insurance or contractual indemnity, it could adversely affect our business, financial condition and results of operations.
Our failure to adequately protect our sensitive information technology systems and critical data and our service providers’ failure to protect their systems and data could have a material adverse effect on our business, results of operations and financial condition.
We increasingly depend on information technology systems that we manage, and others that are managed by our third-party service and equipment providers, to conduct our day-to-day operations, including critical systems on our drilling units, and these systems are subject to risks associated with cyber incidents or attacks. It has been reported that unknown entities or groups have mounted cyber-attacks on businesses and other organizations solely to disable or disrupt computer systems, disrupt operations and, in some cases, steal data. In addition, the US government has issued public warnings that indicate that energy assets might be specific targets of cybersecurity threats. Also, in response to the COVID-19 pandemic, many of our non-operational employees are working remotely, which increases logistical challenges, inefficiencies and operational risks. Working remotely has significantly increased the use of online conferencing services and remote networking, which enable employees to work outside of our corporate infrastructure and, in some cases, use their own personal devices. This remote work model has resulted in an increased demand for information technology resources and may expose us to additional risks of security breaches or other cyber-incidents or attacks, loss of data, fraud and other disruptions as a consequence of more employees accessing sensitive and critical information from remote locations. Due to the nature of cyber-attacks, breaches to our systems or our service or equipment providers’ systems could go undetected for a prolonged period of time. While the Company has a cybersecurity program, a significant cyber-attack could disrupt our operations and result in downtime, loss of revenue, harm to the Company's reputation, or the loss, theft, corruption or unauthorized release of critical data of us or those with whom we do business as well as result in higher costs to correct and remedy the effects of such incidents. If our or our service or equipment providers’ systems for protecting against cyber incidents or attacks prove to be insufficient and an incident were to occur, it could have a material adverse effect on our business, financial condition and results of operations, along with our reputation. Even though we carry cyber insurance that may provide insurance coverage under certain circumstances, we might suffer losses as a result of a security breach that exceeds the coverage available under our policy or for which we do not have coverage.
In addition, laws and regulations governing data privacy and the unauthorized disclosure of confidential or protected information, including the European Union General Data Protection Regulation and recent legislation in various US states, pose increasingly complex compliance challenges and potentially elevate costs, and any failure to comply with these laws and regulations could result in significant penalties and legal liability.
Upgrades, refurbishment and repair of rigs are subject to risks, including delays and cost overruns, that could have an adverse impact on our available cash resources and results of operations.
We will continue to make upgrades, refurbishment and repair expenditures to our fleet from time to time, some of which may be unplanned. In addition, we may reactivate rigs that have been cold or warm stacked and make selective acquisitions of rigs. Our customers may also require certain shipyard reliability upgrade projects for our rigs. These projects and other efforts of this type are subject to risks of cost overruns or delays inherent in any large construction project as a result of numerous factors, including the following:
shortages of equipment, materials or skilled labor;
work stoppages and labor disputes;
unscheduled delays in the delivery of ordered materials and equipment;
local customs strikes or related work slowdowns that could delay importation of equipment or materials;
weather interferences;
difficulties in obtaining necessary permits or approvals or in meeting permit or approval conditions;
design and engineering problems;
inadequate regulatory support infrastructure in the local jurisdiction;
latent damages or deterioration to hull, equipment and machinery in excess of engineering estimates and assumptions;
unforeseen increases in the cost of equipment, labor and raw materials, particularly steel;
unanticipated actual or purported change orders;
client acceptance delays;
disputes with shipyards and suppliers;
delays in, or inability to obtain, access to funding;
shipyard availability, failures and difficulties, including as a result of financial problems of shipyards or their subcontractors; and
failure or delay of third-party equipment vendors or service providers.
22


The failure to complete a rig upgrade, refurbishment or repair on time, or at all, may result in related loss of revenues, penalties, or delay, renegotiation or cancellation of a drilling contract or the recognition of an asset impairment. Additionally, capital expenditures could materially exceed our planned capital expenditures. Moreover, when our rigs are undergoing upgrade, refurbishment and repair, they may not earn a dayrate during the period they are out of service. If we experience substantial delays and cost overruns in our shipyard projects, it could have a material adverse effect on our business, financial condition and results of operations. We currently have no new rigs under construction.
Failure to attract and retain skilled personnel or an increase in personnel costs could adversely affect our operations.
We require skilled personnel to operate and provide technical services and support for our drilling units. In the past, during periods of high demand for drilling services and increasing worldwide industry fleet size, shortages of qualified personnel have occurred. During the last few years of reduced demand, there were layoffs of qualified personnel, who often find work with competitors or leave the industry. As a result, if market conditions improve and we seek to reactivate warm or cold stacked rigs, upgrade our working rigs or purchase additional rigs, we may face shortages of qualified personnel, which would impair our ability to attract qualified personnel for our new or existing drilling units, impair the timeliness and quality of our work and create upward pressure on personnel costs, any of which could adversely affect our operations.
Supplier capacity constraints or shortages in parts or equipment, 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 used in our drilling operations exposes us to volatility in the quality, price and availability of such items. Certain specialized parts and equipment we use in our operations may be available only from a single or small number of suppliers. During the last few years of reduced demand, many of these third-party suppliers reduced their inventories of parts and equipment and, in some cases, reduced their production capacity. If the market for our services improves and we seek to reactivate warm or cold stacked rigs, upgrade our working rigs or purchase additional rigs, these reductions could make it more difficult for us to find equipment and parts for our rigs. A disruption or delay in the deliveries from such third-party suppliers, capacity constraints, production disruptions, price increases, defects or quality-control issues, recalls or other decreased availability or servicing of parts and equipment could adversely affect our ability to reactivate rigs, upgrade working rigs, purchase additional rigs or meet our commitments to customers on a timely basis, adversely impact our operations and revenues by resulting in uncompensated downtime, reduced dayrates, the incurrence of liquidated damages or other penalties or the cancellation or termination of contracts, or increase our operating costs.
We maycontemplate future mergers or acquisitions as part of our business strategy. Acquisitions of other businesses or assets present various risks and uncertainties.
We may pursue growth through the mergers or acquisition of businesses or assets that we believe will enable us to strengthen or broaden our business. We may be unable to implement this element of our strategy if we cannot identify suitable companies, businesses or assets, reach agreement on potential strategic acquisitions on acceptable terms or for other reasons. Moreover, merges and acquisitions involve various risks, including, among other things, (i) difficulties relating to integrating an acquired business and unanticipated changes in customer and other third-party relationships subsequent to acquisition, (ii) diversion of management's attention from day-to-day operations, (iii) failure to realize anticipated benefits, such as cost savings and revenue enhancements, (iv) potentially substantial transaction costs associated with acquisitions, and (v) potential impairment resulting from the overpayment for an acquisition.
Future mergers or acquisitions may require us to obtain additional equity or debt financing, which may not be available on attractive terms. Moreover, to the extent a transaction financed by non-equity consideration results in goodwill, it will reduce our tangible net worth, which might have an adverse effect on credit availability.
Acts of terrorism, piracy and political and social unrest could affect the markets for drilling services, which may have a material adverse effect on our results of operations.
Acts of terrorism and social unrest, brought about by world political events or otherwise, have caused instability in the world’s financial and insurance markets in the past and may occur in the future. Such acts could be directed against companies such as ours. In addition, acts of terrorism, piracy and social unrest could lead to increased volatility in prices for crude oil and natural gas and could affect the markets for drilling services. Insurance premiums could increase and coverage may be unavailable in the future. Government regulations may effectively preclude us from engaging in business activities in certain countries. These regulations could be amended to cover countries where we currently operate or where we may wish to operate in the future.
Our drilling contracts do not generally provide indemnification against loss of capital assets or loss of revenues resulting from acts of terrorism, piracy or political or social unrest. We have limited insurance for our assets providing coverage for physical damage losses resulting from risks, such as terrorist acts, piracy, vandalism, sabotage, civil unrest, expropriation and acts of war, and we do not carry insurance for loss of revenues resulting from such risks.
23


Fluctuations in exchange rates and nonconvertibility of currencies could result in losses to us.
We may experience currency exchange losses when revenues are received or expenses are paid in nonconvertible currencies, when we do not hedge an exposure to a foreign currency, when the result of a hedge is a loss or if any counterparty to our hedge were to experience financial difficulties. We may also incur losses as a result of an inability to collect revenues due to a shortage of convertible currency available to the country of operation, controls over currency exchange or controls over the repatriation of income or capital.
We are a holding company, and we are dependent upon cash flow from subsidiaries to meet our obligations.
We currently conduct our operations through our subsidiaries, and our operating income and cash flow are generated by our subsidiaries. As a result, cash we obtain from our subsidiaries is the principal source of funds necessary to meet our debt service obligations. Unless they are guarantors of our indebtedness, our subsidiaries do not have any obligation to pay amounts due on our indebtedness or to make funds available for that purpose. Contractual provisions or laws, as well as our subsidiaries’ financial condition and operating requirements, may also limit our ability to obtain the cash that we require from our subsidiaries to pay our debt service obligations. Applicable tax laws may also subject such payments to us by our subsidiaries to further taxation.
Future sales or the availability for sale of substantial amounts of the New Shares, or the perception that these sales may occur, could, if the New Shares are listed on a national securities exchange, adversely affect the trading price of the New Shares and could impair our ability to raise capital through future sales of equity securities.
Pursuant to the Memorandum of Association of Noble Corporation, the share capital of Noble is $6,000 divided into 500,000,000 ordinary shares of a par value of $0.00001 each and 100,000,000 shares of a par value of $0.00001, each of such class or classes having the rights as our Board of Directors may determine from time to time. On March 10, 2021, there were 43,536,636 New Shares outstanding and 6,463,182 Penny Warrants (as defined herein) issued and outstanding. In addition, as of March 10, 2021, 8,332,910 Tranche 1 Warrants, 8,332,910 Tranche 2 Warrants and 2,777,698 Tranche 3 Warrants are outstanding and exercisable. We also have 7,716,049 New Shares authorized and initially reserved for issuance pursuant to equity awards under the Noble Corporation 2021 Long-Term Incentive Plan.
A large percentage of the New Shares are held by a relatively small number of investors. We entered into the Equity Registration Rights Agreement (as defined herein) with certain of those investors pursuant to which we have agreed to file a registration statement with the SEC to facilitate potential future sales of such New Shares by them. We intend to apply for a listing of the New Shares on a national securities exchange. If the New Shares are listed on a national securities exchange, sales of a substantial number of the New Shares in the public markets, or even the perception that these sales might occur (such as upon the filing of the aforementioned registration statement), could impair our ability to raise capital through a future sale of, or pay for acquisitions using, our equity securities.
We may issue New Shares or other securities from time to time as consideration for future acquisitions and investments. If any such acquisition or investment is significant, the number of New Shares, or the number or aggregate principal amount, as the case may be, of other securities that we may issue may in turn be substantial. We may also grant registration rights covering those New Shares or other securities in connection with any such acquisitions and investments.
If the New Shares are listed on a national securities exchange, we cannot predict the effect that future sales of New Shares will have on the price at which the New Shares trades or the size of future issuances of New Shares or the effect, if any, that future issuances will have on the market price of the New Shares. Sales of substantial amounts of the New Shares, or the perception that such sales could occur, may, if the New Shares are listed on a national securities exchange, adversely affect the trading price of the New Shares.
Certain shareholders own a significant portion of our outstanding equity securities, and their interests may not always coincide with the interests of other holders of the New Shares.
As noted above, a large percentage of the New Shares are held by a relatively small number of investors. As a result, these investors could have significant influence over all matters presented to our shareholders for approval, including election and removal of our directors, change in control transactions and the outcome of all actions requiring a majority shareholder approval.
The interests of these investors may not always coincide with the interests of the other holders of the New Shares, and the concentration of control in these investors may limit other shareholders’ ability to influence corporate matters. The concentration of ownership and voting power of these investors may also delay, defer or even prevent an acquisition by a third party or other change of control of our Company and may make some transactions more difficult or impossible without their support, even if such events are in the bests interests of our other shareholders. If the New Shares are listed on a national securities exchange, this concentration and voting power may adversely affect the trading price of the New Shares.

Financial and Tax Risks
We may record impairment charges on property and equipment, including rigs and related capital spares.
We evaluate the impairment of property and equipment, which include rigs and related capital spares, whenever events or changes in circumstances (including a decision to cold stack, retire or sell rigs) indicate that the carrying amount of an asset may not be recoverable. An impairment loss on our property and equipment may exist when the estimated undiscounted cash flows expected to result from the use of the asset and its eventual disposition are less than its carrying amount. Any impairment loss recognized represents the excess of the asset’s carrying value over the estimated fair value. As part of this analysis, we make assumptions and estimates regarding future market conditions. To the extent actual results do not meet our estimated assumptions, for a given rig or piece of equipment,we may take an impairment loss in the future. In addition, we may also take an impairment loss on capital spares and other capital equipment when we deem the value of those items has declined due to factors like obsolescence, deterioration or damage. Based upon our impairment analyses for the years ended December 31, 2020 and 2019, we recorded impairment charges of $3.9 billion and $615.3 million, respectively, on various rigs and certain capital spares during those periods. There can be no assurance that we will not have to take additional impairment charges in the future if current depressed market conditions persist, or that we will be able to return cold stacked rigs to service in the time frame and at the reactivation costs or at the dayrates that we projected. It is reasonably possible that the estimate of undiscounted cash flows may change in the near term, resulting in the need to write down the affected assets to their corresponding estimated fair values.
The Exit Credit Agreement contains various restrictive covenants limiting the discretion of our management in operating our business.
The Exit Credit Agreement contains various restrictive covenants that may limit our management’s discretion in certain respects. In particular, the Exit Credit Agreement limits Finco’s ability and the ability of its restricted subsidiaries to, among other things and subject to certain limitations and exceptions, (i) incur, assume or guarantee additional indebtedness; (ii) pay dividends or distributions on capital stock or redeem or repurchase capital stock; (iii) make investments; (iv) repay, redeem or amend certain indebtedness; (v) sell stock of its subsidiaries; (vi) transfer or sell assets; (vii) create, incur or assume liens; (viii) enter into transactions with certain affiliates; (ix) merge or consolidate with or into any other person or undergo certain other fundamental changes; and (x) enter into certain burdensome agreements. In addition, the Exit Credit Agreement obligates Finco and its restricted subsidiaries to comply with certain financial maintenance covenants and, under certain conditions, to make mandatory prepayments and reduce the amount of credit available under the Exit Credit Facility, all as described in Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations— Liquidity and Capital Resources— Post-emergence Debt—Senior Secured Exit Revolving Credit Facility.” Such mandatory prepayments and commitment reductions may affect cash available for use in the Company’s business. Our failure to comply with these covenants could result in an event of default which, if not cured or waived, could result in all obligations under the Exit Credit Facility to be declared due and payable immediately and all commitments thereunder to be terminated.
Changes in the method of determining the London Interbank Offered Rate, or the replacement of the London Interbank Offered Rate with an alternative reference rate, may adversely affect interest expense related to outstanding debt.
The loans outstanding under the Exit Credit Facility (as defined herein) bear interest at a rate per annum equal to the applicable margin plus, at Finco’s option, either: (i) the reserve-adjusted London Interbank Offered Rate (“LIBOR”) or (ii) a base rate. On July 27, 2017, the Financial Conduct Authority in the UK, which regulates LIBOR, announced that it intends to phase out LIBOR as a benchmark by the end of 2021. It is unclear if LIBOR will cease to exist at the end of 2021, when it is intended to be phased out or if new methods of calculating LIBOR will be established such that it continues to exist after 2021. While the Exit Credit Facility, which has a term that extends beyond 2021, contains “fallback” provisions providing for alternative rate calculations upon the occurrence of certain events related to the phase-out of LIBOR, these “fallback” provisions may not adequately address the actual changes to LIBOR or successor rates. Although the Secured Overnight Financing Rate is expected to be the alternative rate that replaces LIBOR, we cannot predict what margin adjustments and related terms would be negotiated in connection with the “fallback” provisions. As a result, our interest expense could increase. In addition, the overall financial markets may be disrupted as a result of the phase-out or replacement of LIBOR. Uncertainty as to the nature of such potential phase-out and alternative reference rates or disruption in the financial market could have a material adverse effect on our financial condition, results of operations and cash flows.
A loss of a major tax dispute or a successful tax challenge to our operating structure, intercompany pricing policies or the taxable presence of our subsidiaries in certain countries could result in a higher tax rate on our worldwide earnings, which could result in a material adverse effect on our financial condition and results of operations.
Income tax returns that we file will be subject to review and examination. We recognize the benefit of income tax positions we believe are more likely than not to be sustained upon challenge by a tax authority. If any tax authority successfully challenges our operational structure, intercompany pricing policies or the taxable presence of our subsidiaries in certain countries, if the terms of certain income tax treaties are
25


interpreted in a manner that is adverse to our structure, or if we lose a material tax dispute in any country, our effective tax rate on our worldwide earnings could increase substantially and result in a material adverse effect on our financial condition.
Our consolidated effective income tax rate may vary substantially from one reporting period to another.
We cannot provide any assurances as to what our 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 the UK, US, Switzerland and other tax laws, regulations or treaties or the interpretation or enforcement thereof, changes in the administrative practices and precedents of tax authorities or any reclassification or other matter (such as changes in applicable accounting rules) that increases the amounts we have provided for income taxes or deferred tax assets and liabilities in our consolidated financial statements. For example, the Organization for Economic Cooperation and Development (“OECD”) has issued its final reports on Base Erosion and Profit Shifting, which generally focus on situations where profits are earned 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 enacted changes to their tax laws in response to the OECD recommendations or otherwise and these and other countries may enact changes to their tax laws or practices in the future (prospectively or retroactively), which may have a material adverse effect on our financial position, operating results and/or cash flows.
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. 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. 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. If we are unable to mitigate the negative consequences of any change in law, audit, business activity or other matter, this could cause our consolidated effective income tax rate to increase and cause a material adverse effect on our financial position, operating results and/or cash flows.
Pension expenses associated with our retirement benefit plans may fluctuate significantly depending upon changes in actuarial assumptions, future investment performance of plan assets and legislative or other regulatory actions.
A portion of our current and retired employee population is covered by pension and other post-retirement benefit plans, the costs of which are dependent upon various assumptions, including estimates of rates of return on benefit plan assets, discount rates for future payment obligations, mortality assumptions, rates of future cost growth and trends for future costs. In addition, funding requirements for benefit obligations of our pension and other post-retirement benefit plans are subject to legislative and other government regulatory actions. Future changes in estimates and assumptions associated with our pension and other post-retirement benefit plans could have a material adverse effect on our financial condition, results of operations, cash flows and/or financial disclosures.
Regulatory and Legal Risks
Governmental laws and regulations may add to our costs, result in delays, or limit our drilling activity.
Our business is affected by public policy and laws and regulations relating to the energy industry in the geographic areas where we operate.
The drilling industry is dependent on demand for services from the oil and gas exploration and production industry, and accordingly, we are directly affected by the adoption of laws and regulations that for economic, environmental or other policy reasons curtail exploration and development drilling for oil and gas. We may be required to make significant capital expenditures to comply with governmental laws and regulations. Governments in some foreign countries are increasingly active in regulating and controlling the ownership of concessions, the exploration for oil and gas, and other aspects of the oil and gas industries. There is increasing attention in the United States and worldwide concerning the issue of climate change and the effect of greenhouse gases, or GHGs, and other sustainability and energy transition matters. This increased attention may result in new environmental laws or regulations that may unfavorably impact us, our suppliers and our customers.
The modification of existing laws or regulations or the adoption of new laws or regulations that result in the curtailment of exploratory or developmental drilling for oil and gas could materially and adversely affect our operations by limiting drilling opportunities increasing our cost of doing business, discouraging our customers from drilling for hydrocarbons, disrupting revenue through permitting or similar delays, or subjecting us to liability. For example, on January 20, 2021, the Acting Secretary for the Department of the Interior signed an order effectively suspending new fossil fuel leasing and permitting on federal lands, including in the US Gulf of Mexico, for 60 days. Then on January 27, 2021, President Biden issued an executive order indefinitely suspending new oil and natural gas leases on public lands or in offshore waters pending completion of a comprehensive review and reconsideration of federal oil and gas permitting and leasing practices. Demand for our services could be diminished during this review period. Further, to the extent that the review results in the development of additional restrictions on
26


offshore drilling, limitations on the availability of offshore leases, or restrictions on the ability to obtain required permits, it could have a material adverse impact on our operations by reducing drilling opportunities and the demand for our services.
Increasing attention to environmental, social and governance matters may impact our business and financial results.
In recent years, increasing attention has been given to corporate activities related to environmental, social and governance (“ESG”) matters in public discourse and the investment community. A number of advocacy groups, both domestically and internationally, have campaigned for governmental and private action to promote change at public companies related to ESG matters, including through the investment and voting practices of investment advisers, public pension funds, universities and other members of the investing community. These activities include increasing attention and demands for action related to climate change and energy transition matters, such as promoting the use of substitutes to fossil fuel products and encouraging the divestment of fossil fuel equities, as well as pressuring lenders and other financial services companies to limit or curtail activities with fossil fuel companies. If this were to continue, it could have a material adverse effect on our ability to access equity capital markets. Members of the investment community have begun to screen companies such as ours for sustainability performance, including practices related to GHGs and climate change. If we are unable to find economically viable, as well as publicly acceptable, solutions that reduce our GHG emissions and/or GHG intensity for new and existing projects, we could experience additional costs or financial penalties, delayed or cancelled projects, and/or reduced production and reduced demand for hydrocarbons, which could have a material adverse effect on our earnings, cash flows and financial condition.
Any violation of anti-bribery or anti-corruption laws, including the Foreign Corrupt Practices Act, the United Kingdom Bribery Act, or similar laws and regulations could result in significant expenses, divert management attention, and otherwise have a negative impact on us.
We operate in countries known to have a reputation for corruption. We are subject to the risk that we, our affiliated entities or their respective officers, directors, employees and agents may take action determined to be in violation of such anti-corruption laws, including the US Foreign Corrupt Practices Act of 1977 (the FCPA), the United Kingdom Bribery Act 2010 (the UK Bribery Act) and similar laws in other countries. Any violation of the FCPA, UK Bribery Act or other applicable anti-corruption laws could result in substantial fines, sanctions, civil and/or criminal penalties and curtailment of operations in certain jurisdictions and might adversely affect our business, financial condition and results of operations. In addition, actual or alleged violations could damage our reputation and ability to do business. Further, detecting, investigating and resolving actual or alleged violations is expensive and can consume significant time and attention of our senior management.
Changes in, compliance with, or our failure to comply with the certain laws and regulations may negatively impact our operations and could have a material adverse effect on our results of operations.
Our operations are subject to various laws and regulations in countries in which we operate, including laws and regulations relating to:
the environment and the health and safety of personnel;
the importing, exporting, equipping and operation of drilling rigs;
currency exchange controls;
oil and gas exploration and development;
taxation of offshore earnings and earnings of expatriate personnel; and
use and compensation of local employees and suppliers by foreign contractors.
Public and governmental scrutiny of the energy industry has resulted in increased regulations being proposed and often implemented. In addition, existing regulations might be revised or reinterpreted, new laws, regulations and permitting requirements might be adopted or become applicable to us, our rigs, our customers, our vendors or our service providers, and future changes in laws and regulations could significantly increase our costs and could have a material adverse effect on our business, financial condition and results of operations. In addition, we may be required to post additional surety bonds to secure performance, tax, customs and other obligations relating to our rigs in jurisdictions where bonding requirements are already in effect and in other jurisdictions where we may operate in the future. These requirements would increase the cost of operating in these countries, which could materially adversely affect our business, financial condition and results of operations.
From time to time, new rules, regulations and requirements regarding oil and gas development have been proposed and implemented by BOEM, BSEE or the United States Congress, as well as other jurisdictions outside the United States, that could materially limit or prohibit, and increase the cost of, offshore drilling. For example, in July 2016, BOEM and BSEE finalized a rule revising and adding requirements for drilling on the US Arctic Outer Continental Shelf. Similarly, in April 2016, BSEE announced a final blowout preventer systems and well control rule. BSEE also finalized a rule in September 2016 concerning production safety systems for oil and natural gas operations on the Outer Continental Shelf. BSEE issued final rules amending both the September 2016 production safety systems rule and the April 2016 blowout preventer systems and well control rule in September 2018 and May 2019, respectively. BSEE also published a proposed rule in December 2020 that would revise the 2016 rule concerning drilling on the US Arctic Outer Continental Shelf. In addition, BOEM released a Notice to Lessees and Operators in the Outer Continental Shelf (NTL) in September 2016 that updated offshore bonding requirements. The NTL was only partially implemented before being rescinded and replaced by a proposed rule addressing offshore bonding published in October 2020. However, on January 20, 2021, President Biden issued executive orders freezing the issuance of new rules pending further review and directing
27


all executive departments and agencies to review and consider suspending, revising, or rescinding all regulations issued between January 20, 2017 and January 20, 2021 determined to be inconsistent with President Biden’s environmental and climate goals. To the extent these recent proposed and final rules are reviewed and determined to be inconsistent under the executive orders, BOEM and BSEE could issue new rules reinstating the requirements of the 2016 rules and/or reimplement the NTL.
We are also subject to increasing regulatory requirements and scrutiny in the North Sea jurisdictions and other countries. New rules, regulations and requirements, or a return to the requirements of the 2016 versions of the BSEE and BOEM regulations, including the adoption of new safety requirements and policies relating to the approval of drilling permits, restrictions on oil and gas development and production activities in the US Gulf of Mexico and elsewhere, implementation of safety and environmental management systems, mandatory third party compliance audits, and the promulgation of numerous Notices to Lessees or similar new regulatory requirements outside of theUnited States, may impact our operations by causing increased costs, delays and operational restrictions. If new regulations, policies, operating procedures and the possibility of increased legal liability resulting from the adoption or amendment of rules and regulations applicable to our operations in the United States or other jurisdictions are viewed by our current or future customers as a significant impairment to expected profitability on projects, then they could discontinue or curtail their offshore operations in the impacted region, thereby adversely affecting our operations by limiting drilling opportunities or imposing materially increased costs.
We could also be affected by challenges and restrictions to offshore operations by environmental groups, costal states and the federal government. For example, in December 2018, environmental groups challenged incidental harassment authorizations issued by the National Marine Fisheries Service that allow companies to conduct air gun seismic surveys for oil and gas exploration off the Atlantic coast. The attorney generals for ten US coastal states also intervened as plaintiffs. The litigation concluded in October 2020 and the authorizations expired in November 2020. Restrictions on authorizations needed to conduct seismic surveys could impact our customers’ ability to identify oil and gas reserves, thereby reducing demand for our services. Several coastal states have also taken steps to prohibit offshore drilling. For example, California passed laws in September 2018 barring the construction of new oil drilling-related infrastructure in state waters. Similarly, in November 2018, voters in Florida approved an amendment to the state constitution that would ban oil and gas drilling in offshore state waters. Such initiatives could reduce opportunities for our customers and thereby reduce demand for our services. In addition, the federal government has taken steps to restrict offshore drilling opportunities. For example, on January 20, 2021, the Acting Secretary for the Department of the Interior signed an order effectively suspending new fossil fuel leasing and permitting on federal lands, including in the US Gulf of Mexico, for 60 days. Then on January 27, 2021, President Biden issued an executive order indefinitely suspending new oil and natural gas leases on public lands or in offshore waters pending completion of a comprehensive review and reconsideration of federal oil and gas permitting and leasing practices. Demand for our services could be diminished during this review period. Further, to the extent that the review results in the development of additional restrictions on offshore drilling, limitations on the availability of offshore leases, or restrictions on the ability to obtain required permits, it could have a material adverse impact on our operations by reducing drilling opportunities and the demand for our services.
Adverse effects may continue as a result of the uncertainty of ongoing inquiries, investigations and court proceedings, or additional inquiries and proceedings by federal or state regulatory agencies or private plaintiffs. In addition, we cannot predict the outcome of any of these inquiries or whether these inquiries will lead to additional legal proceedings against us, civil or criminal fines or penalties, or other regulatory action, including legislation or increased permitting requirements. Legal proceedings or other matters against us, including environmental matters, suits, regulatory appeals, challenges to our permits by citizen groups and similar matters, might result in adverse decisions against us. The result of such adverse decisions, both individually or in the aggregate, could be material and may not be covered fully or at all by insurance.
Our operations are subject to numerous laws and regulations relating to the protection of the environment and of human health and safety, and compliance with these laws and regulations could impose significant costs and liabilities that exceed our current expectations.
Substantial costs, liabilities, delays and other significant issues could arise from environmental, health and safety laws and regulations covering our operations, and we may incur substantial costs and liabilities in maintaining compliance with such laws and regulations. Our operations are subject to extensive international conventions and treaties, and national or federal, state and local laws and regulations, governing environmental protection, including with respect to the discharge of materials into the environment and the security of chemical and industrial facilities. These laws govern a wide range of environmental issues, including:
the release of oil, drilling fluids, natural gas or other materials into the environment;
air emissions from our drilling rigs or our facilities;
handling, cleanup and remediation of solid and hazardous wastes at our drilling rigs or our facilities or at locations to which we have sent wastes for disposal;
restrictions on chemicals and other hazardous substances; and
wildlife protection, including regulations that ensure our activities do not jeopardize endangered or threatened animals, fish and plant species, nor destroy or modify the critical habitat of such species.
28


Various governmental authorities have the power to enforce compliance with these laws and regulations and the permits issued under them, oftentimes requiring difficult and costly actions. Failure to comply with these laws, regulations and permits, or the release of oil or other materials into the environment, may result in the assessment of administrative, civil and criminal penalties, the imposition of remedial obligations, the imposition of stricter conditions on or revocation of permits, the issuance of moratoria or injunctions limiting or preventing some or all of our operations, delays in granting permits and cancellation of leases, or could affect our relationship with certain consumers.
There is an inherent risk of the incurrence of environmental costs and liabilities in our business, some of which may be material, due to the handling of our customers’ hydrocarbon products as they are gathered, transported, processed and stored, air emissions related to our operations, historical industry operations, and water and waste disposal practices. For example, we, as an operator of mobile offshore drilling units in navigable US waters and certain offshore areas, including the US Outer Continental Shelf, are liable for damages and for the cost of removing oil spills for which we may be held responsible, subject to certain limitations. Our operations may involve the use or handling of materials that are classified as environmentally hazardous. Environmental laws and regulations may expose us to liability for the conduct of or conditions caused by others or for acts that were in compliance with all applicable laws at the time they were performed. Joint, several or strict liability may be incurred without regard to fault under certain environmental laws and regulations for the remediation of contaminated areas and in connection with past, present or future spills or releases of natural gas, oil and wastes on, under, or from past, present or future facilities. Private parties may have the right to pursue legal actions to enforce compliance as well as to seek damages for non-compliance with environmental laws and regulations or for personal injury or property damage arising from our operations. In addition, increasingly strict laws, regulations and enforcement policies could materially increase our compliance costs and the cost of any remediation that may become necessary. Our insurance may not cover all environmental risks and costs or may not provide sufficient coverage if an environmental claim is made against us.
Our business may be adversely affected by increased costs due to stricter pollution control equipment requirements or liabilities resulting from non-compliance with required operating or other regulatory permits. Also, we might not be able to obtain or maintain from time to time all required environmental regulatory approvals for our operations. If there is a delay in obtaining any required environmental regulatory approvals, or if we fail to obtain and comply with them, the operation or construction of our facilities could be prevented or become subject to additional costs. In addition, the steps we could be required to take to bring certain facilities into regulatory compliance could be prohibitively expensive, and we might be required to shut down, divest or alter the operation of those facilities, which might cause us to incur losses.
We make assumptions and develop expectations about possible expenditures related to environmental conditions based on current laws and regulations and current interpretations of those laws and regulations. If the interpretation of laws or regulations, or the laws and regulations themselves, change, our assumptions may change, and new capital costs may be incurred to comply with such changes. In addition, new environmental laws and regulations might adversely affect our operations, as well as waste management and air emissions. For instance, governmental agencies could impose additional safety requirements, which could affect our profitability. Further, new environmental laws and regulations might adversely affect our customers, which in turn could affect our profitability.
Finally, although some of our drilling rigs will be separately owned by our subsidiaries, under certain circumstances a parent company and all of the unit-owning affiliates in a group under common control engaged in a joint venture could be held liable for damages or debts owed by one of the affiliates, including liabilities for oil spills under environmental laws. Therefore, it is possible that we could be subject to liability upon a judgment against us or any one of our subsidiaries.
Unionization efforts and labor regulations in certain countries in which we operate could materially increase our costs or limit our flexibility.
Certain of our employees and contractors in international markets are represented by labor unions or work under collective bargaining or similar agreements, which are subject to periodic renegotiation. Efforts may be made from time to time to unionize portions of our workforce. In addition, we may be subject to strikes or work stoppages and other labor disruptions in the future. Additional unionization efforts, new collective bargaining agreements or work stoppages could materially increase our costs, reduce our revenues or limit our operational flexibility.
Any failure to comply with the complex laws and regulations governing international trade could adversely affect our operations.
The shipment of goods, services and technology across international borders subjects our business to extensive trade laws and regulations. Import activities are governed by unique customs laws and regulations in each of the countries of operation. 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 economic sanctions against certain countries, persons and other entities that may restrict or prohibit transactions involving such countries, persons and entities. US sanctions, in particular, are targeted against certain countries that are heavily involved in the petroleum and petrochemical industries, which includes drilling activities.
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
29


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. Any failure to comply with applicable legal and regulatory trading obligations could also result in criminal and civil penalties and sanctions, such as fines, imprisonment, debarment from government contracts, seizure of shipments and loss of import and export privileges.
Currently, we do not, nor do we intend to, operate in countries that are subject to significant sanctions and embargoes imposed by the US government or identified by the US government as state sponsors of terrorism, such as the Crimean region of the Ukraine, Cuba, Iran, North Korea, Sudan and Syria. The US sanctions and embargo laws and regulations vary in their application, as they do not all apply to the same covered persons or proscribe the same activities, and such sanctions and embargo laws and regulations may be amended or strengthened over time. There can be no assurance that we will be in compliance in the future, particularly as the scope of certain laws may be unclear and may be subject to changing interpretations. Any such violation could result in fines or other penalties and could result in some investors deciding, or being required, to divest their interest, or not to invest, in us. In addition, certain institutional investors may have investment policies or restrictions that prevent them from holding securities of companies that have contracts with countries identified by the US government as state sponsors of terrorism. In addition, our reputation and the market for our securities may be adversely affected if we engage in certain other activities, such as entering into drilling contracts with individuals or entities in countries subject to significant US sanctions and embargo laws that are not controlled by the governments of those countries, or engaging in operations associated with those countries pursuant to contracts with third parties that are unrelated to those countries or entities controlled by their governments.
We are subject to litigation that could have an 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, asbestos and other 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 may have an adverse effect on us because of potential negative outcomes, legal fees, the allocation of management’s time and attention, and other factors.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.
The following discussion is intended to assist you in understanding our financial position at December 31, 20172020 and 2016,2019, and our results of operations for each of the years in the three-year period ended December 31, 2017.2020. The following discussion should be read in conjunction with the consolidated financial statements and related notes contained in this Annual Report on Form 10-K for the year ended December 31, 20172020 filed by Noble-UKNoble and Noble-Cayman.

Executive Overview
We provide contract drilling services to the international oil and gas industry with our global fleet of mobile offshore drilling units. As of the filing date of this Annual Report on Form 10-K, our fleet of 28 drilling rigs consisted of eight drillships, six semisubmersibles and 14 jackups strategically deployed worldwide. We typically employ each drilling unit under an individual contract. Although the final terms of the contracts result from negotiations with our customers, many contracts are awarded based upon a competitive bidding process.
Our 2017 financial and operating results from continuing operations include:
operating revenues totaling $1.2 billion;
net loss of $516.5 million, or $2.10 per diluted share, which includes a $94.8 million after-tax impairment charge recognized on three of our rigs and certain capital spare equipment; and
net cash from operating activities totaling $453.9 million.
The challenging business environment for offshore drillers continued during 2017 and into 2018. An industry-wide rig supply imbalance has remained in place, as curtailed offshore spending by customers contributed to a growing number of rigs without drilling programs. In addition, newbuild rigs ordered prior to the decline in industry activity continue to exit shipyards, while the delivery of other newbuild rigs have been delayed into the future. In either case, these rigs add to the supply imbalance. Since 2015, the industry has experienced a higher level of fleet attrition, as rigs are removed from the global supply due to a number of factors, including advanced service life, high maintenance and reactivation costs and limited customer appeal. However, the pace of attrition has been significantly less than what is required to ameliorate the capacity imbalance. In addition, our customers have adopted a cautious approach to offshore spending as crude oil prices have declined from approximately $112 per barrel for Brent crude on June 30, 2014 to as low as approximately $30 per barrel in January 2016, before improving to $65 per barrel on February 20, 2018. Although crude oil prices have been less volatile during 2017, we expect that the offshore drilling programs of operators will remain curtailed, until higher crude oil prices are sustained and our customers' capital spending increases. Until then, further decline in rig utilization and dayrates is possible.
We expect the business environment for the remainder of 2018 to remain challenging. The uncertainty of the viability and length of reductions in production agreed to by the Organization of Petroleum Exporting Countries (“OPEC”), the incremental production capacity in non-OPEC countries, including growing production from U.S. shale activity, the current U.S. political environment and fluid sentiment in oil markets are contributing to an uncertain oil price environment, leading to considerable uncertainty in our customers’ production spending plans. However, steady demand growth, the lack of production investments in various countries around the world and the production limits agreed to by OPEC have helped to establish market conditions supporting higher sustained crude prices recently. In general, recent contract awards have been subject to an extremely competitive bidding process. As a result, the contracts have been for dayrates that are substantially lower than rates were for the same class of rigs before this period of imbalance. We cannot give any assurances as to when conditions in the offshore drilling market will improve, or when the oversupply of available drilling rigs will end. While current market conditions persist, we will continue to focus on fleet utilization improvements, cost control initiatives and financial discipline, including the preservation of liquidity. The current business environment could lead to us stacking or retiring additional rigs.
We cannot predict the future level of demand or dayrates for our services, or future conditions in the offshore contract drilling industry. However, we believe in the long-term fundamentals for the industry and believe we are strategically well positioned during this market downturn as a result of our substantial backlog, modern fleet of high-specification rigs and strong operational capability. We also believe that these strengths will help us take advantage of any future market upcycle. Also, we expect the ultimate recovery to benefit from any sustained under-investment by customers during this current phase of the market cycle. Acceleration in customers' offshore spending, in combination with further fleet attrition, should contribute to a balanced rig supply over time.
Our business strategy focuses on a balanced, high-specification fleet of both floating and jackup rigs, and the deployment of our drilling rigs in importantestablished and emerging offshore oil and gas basins around the world.
We have expanded our drillingemphasize safe operations, environmental stewardship, social responsibility, and fleetrobust governance to sustain the superior performance and maximize stakeholder value achieved through our newbuild program. We took deliveryqualified and well-trained crews, the care of our last remaining newbuild,surroundings and local communities, an effective management system, and a superior fleet. We also carefully manage rig operating costs through innovative systems and processes, including the heavy-duty, harsh environment jackup,use of data analytics and predictive maintenance technology.
As of the filing date of this Annual Report on Form 10-K, our fleet of 19 drilling rigs consisted of seven floaters and 12 jackups strategically deployed worldwide. We typically employ each drilling unit under an individual contract, and many contracts are awarded based upon a competitive bidding process.
Our 2020 financial and operating results from continuing operations include:
operating revenues totaling $1.0 billion, a decrease of 26% from prior year;
net loss attributable to Noble Lloyd Noble,Corporation of $4.0 billion, or $15.86 per diluted share, which includes a $3.9 billion before-tax impairment charge recognized on 16 of our rigs and certain capital spare equipment; and
net cash provided by operating activities totaling $273.2 million, an increase of 46% from prior year.
Demand for our services is highly competitive and, in July 2016.significant part, a function of the worldwide demand for oil and gas and the global supply of mobile offshore drilling units. Since late 2014, the offshore drilling industry has experienced a severe and prolonged downturn stemming from the combination of an oversupply of competing drilling rigs that resulted from the new build rig influx of the 2010s, weak and volatile crude oil prices, and the advancement of onshore opportunities and technology. The Noble Lloyd Noble commenced operations in November 2016 under a four-year contractCompany entered 2020 cautiously optimistic with the prospects for the offshore drilling market continuing to improve; however, the combined effects of the pandemic and the steep decline in the North Sea. Although we plandemand for oil have resulted in significantly reduced global economic activity. These factors in concert led to prioritize capital preservation and liquidity based on current market conditions, from time to time we will also continue to evaluateheightened competition for opportunities to enhancere-contract our fleet, particularly focusingrigs upon the expiration of existing contracts.
Recent Events
Emergence from Chapter 11. In connection with the Chapter 11 Cases (as defined below) and the Plan, on higher specification rigs,and prior to execute the increasingly complex drilling programs required by our customers.Effective Date, Legacy Noble and certain of its subsidiaries effectuated certain restructuring transactions, pursuant to which Legacy Noble transferred to Noble substantially all of the subsidiaries, and other assets, of Legacy Noble. On the Effective Date, Legacy Noble successfully completed its financial restructuring and Legacy Noble and its debtor affiliates emerged from the Chapter 11 Cases. For additional information regarding the Chapter 11 Cases, see “—Chapter 11 Proceedings and Going Concern” below
As a result of the financial restructuring, Noble emerged from bankruptcy on the Effective Date with a substantially delevered balance sheet and less than $400.0 million of debt. Noble’s capital structure as of the Effective Date includes a $675.0 million revolving credit facility, of which $177.5 million is drawn as of March 10, 2021, and $216.0 million Second Lien Notes (as defined herein). On the Effective Date, Legacy Noble’s ordinary shares were cancelled and New Shares were issued to Legacy Noble’s former bondholders. Certain former bondholders and former equity holders of Legacy Noble were also issued warrants to purchase shares of the Company.
Spin-off of Paragon Offshore plc
OnMatter. In August 1, 2014, Noble-UKLegacy Noble completed the Spin-off of a majority of its standard specification offshore drilling business through a pro rata distribution of all of the ordinary shares of its wholly-owned subsidiary, Paragon Offshore, to the holders of Legacy Noble’s ordinary shares.


In February 2016, Paragon Offshore sought approval of a pre-negotiated plan of reorganization (the “Prior Plan”) by filingfiled for voluntary reliefprotection under Chapterchapter 11 of the United States Bankruptcy Code. As part of the Prior Plan, we entered into a settlement agreementCode in February 2016, and in connection with Paragon Offshore (the “Settlement Agreement”). The Prior Plan was rejected by theOffshore’s emergence from bankruptcy court in October 2016.
July 2017, all claims it may have had against Legacy Noble were transferred to a litigation trust. In AprilDecember 2017, Paragon Offshore filed an updated disclosure statement and a revised plan of reorganization (the “New Plan”) in its bankruptcy proceeding. Under the New Plan, including Paragon Offshore’s revised business plan, Paragon Offshore no longer needed the Mexican tax bonding that Noble-UK was to provide under the Settlement Agreement. As a result, the Settlement Agreement was no longer applicable to the ongoing business of Paragon Offshore. Consequently, Paragon Offshore abandoned the Settlement Agreement as part of the New Plan, and the Settlement Agreement was terminated at the time of the filing of the New Plan. On May 2, 2017, Paragon Offshore announced that it had reached an agreement in principle with both its secured and unsecured creditors to revise the New Plan to, among other things, create and fund a $10.0 million litigation trust to pursue litigation against us. On June 7, 2017, the revised New Plan was approved by the bankruptcy courtfiled fraudulent conveyance and Paragon Offshore emerged from bankruptcy on July 18, 2017.
On December 15, 2017, the litigation trust filedrelated claims relating to the Spin-off in an action (the “Action”) against usLegacy Noble and certain of ourits subsidiaries (the “Noble Defendants”), as well as certain of Legacy Noble’s and then current and former officers and directors in the Delaware bankruptcy court that heard Paragon Offshore’s bankruptcy.(the “Individual Defendants”). The complaint alleges claimslitigation trust sought total damages of alleged actualapproximately $2.6 billion and constructive fraudulent conveyance, unjust enrichment and recharacterization of intercompany notes as equity claims against Noble and claims of breach of fiduciary duty and aiding and abetting breach of fiduciary dutyunspecified amounts against the officer and director defendants. We continue to believe that Paragon Offshore, atIndividual Defendants. On September 23, 2020, the time of the Spin-off, was properly funded, solvent and had appropriate liquidity and that the claims brought byNoble Defendants entered into a settlement agreement (the “Settlement Agreement”) with the litigation trust are without meritto fully and will be contested vigorously by us.
If any offinally settle the disputes among them in the Action on the terms set forth in the Settlement Agreement and, subject to certain terms and conditions, to allow the litigation trust’s claims are successful, or if we elect to settle any claims, any damages or other amounts we would be required to or agree to pay could have a material adverse effect on our business, financial condition and results of operations. The litigation isproceed against the Individual Defendants in the very early stages, no schedule has been established,Delaware Court. The Settlement Agreement further provided that it was a compromise settlement that is not in any respect, for any purpose, to be deemed or construed to be an express or implied admission of any liability or wrongdoing or otherwise. On October 9, 2020, the Bankruptcy Court (as defined below) entered an order approving the Debtors' (as defined below) entry into the Settlement Agreement, which also contemplated a potential global settlement including the Individual Defendants.
On February 3, 2021, the Noble Defendants, the Individual Defendants and we are not able to predict when, or if, the matters will go to trial or otherwise be concluded. We may be required to establish reserves on our financial statements in advance of the conclusion of the litigation. Such reserves may be substantial and could have a material adverse effect on our financial condition as presented in such financial statements.
Prior to the completion of the Spin-off, Noble-UK and Paragon Offshorelitigation trust entered into a series of agreementsglobal settlement. Pursuant to effect the separationglobal settlement, among other things, the Debtors made a $7.7 million payment to the litigation trust, and Spin-off and govern the relationship between the parties after the Spin-off (the “Separation Agreements”),all claims brought against all

defendants, including the Master Separation Agreement (the “MSA”)Noble Defendants and the Tax Sharing Agreement (the “TSA”).
As part of its final bankruptcy plan, Paragon Offshore rejected the Separation Agreements. Accordingly, the indemnity obligations that Paragon Offshore potentially would have owed us under the Separation Agreements have now terminated, including indemnities arising under the MSAIndividual Defendants were settled and the TSA in respect of obligations relatedreleased. The global settlement was subject to Paragon Offshore’s business that were incurred through Noble-retained entities prior to the Spin-off. Likewise, any potential indemnity obligations that we would have owed Paragon Offshore under the Separation Agreements, including those under the MSA and the TSA in respect of Noble-UK’s business that was conducted prior to the Spin-off through Paragon Offshore-retained entities, are now also extinguished. In the absence of the Separation Agreements, liabilities relating to the respective parties will be borneapproval by the owner of the legal entity or asset at issueDelaware Court, which approval was granted on February 24, 2021. See “Note 16— Commitments and neither party will look to an allocation based on the historic relationship of an entity or asset to one of the party’s business, as had been the case under the Separation Agreements.
The rejection and ultimate termination of the indemnity and related obligations under the Separation Agreements has resulted in a number of accounting charges and benefits for the year ended December 31, 2017, and such termination may continue to affect us in the future as liabilities arise for which we would have been indemnified by Paragon Offshore or would have had to indemnify Paragon Offshore. We do not expect that, overall, the rejection of the Separation Agreements by Paragon Offshore will have a material adverse effect on our financial condition or liquidity. However, any loss we experience with respect to which we would have been able to secure indemnification from Paragon Offshore under one or more of the Separation Agreements could have an adverse impact on our results of operations in any period, which impact may be material depending on our results of operations during this down-cycle.
During the year ended December 31, 2017, we recognized net charges of $15.9 million, with a non-cash loss of $1.5 million recorded in “Net loss from discontinued operations, net of tax” on our Consolidated Statement of Operations relating to Paragon Offshore's emergence from bankruptcy.
U.S. Federal Income Tax Reform
On December 22, 2017, the President of the United States signed into law legislation informally known as the Tax Cuts and Jobs Act (the “Act”). The Act represents major tax reform legislation that, among other provisions, reduces the U.S. corporate tax rate. For more information on the Act and its effect on our consolidated financial statements, see “—Critical Accounting Policies” and Part II, Item 8, “Note 10— Income Taxes.”



Impairment
As more thoroughly described in “Note 6— Impairment”Contingencies” to our consolidated financial statements included in Part II, Item 8 of this Annual Report on Form 10-K for more information.
Outlook
The offshore drilling industry remains highly competitive. We believe the convergence of events in 2020 and early 2021 have lengthened an already challenging and slow recovery in our industry. Despite these challenges and demand projections, we believe that oil and gas demand will rebalance and oil and gas will remain an important portion of the world’s energy mix. We expect that the return of stable oil demand and prices coupled with the continued attrition of rigs in the global offshore fleet will bring improved market conditions for our services.
Noble emerged from the Chapter 11 Cases with a high-specification fleet of 19 rigs, balanced across jackups and floaters. Our floating and jackup drilling fleet is among the youngest, most modern and versatile in the industry, with the majority of our rigs having been delivered since 2011, and is well positioned to compete as market dynamics improve. Our fleet consists predominately of technologically advanced units, equipped with sophisticated systems and components prepared to execute our customers’ increasingly complicated offshore drilling programs safely and with greater efficiency, contributing to an overall reduction of our carbon footprint. We remain committed to safely and efficiently serving the needs of our customers globally and we set several company safety records during 2020.
At December 31, 2020, we had a total contract drilling services backlog of approximately $1.6 billion, which includes a commitment of approximately 67 percent of available days for 2021. For additional information regarding our backlog, see “—Contract Drilling Services Backlog” below.
Chapter 11 Proceedings and Going Concern
On July 31, 2020 (the “Petition Date”), Legacy Noble and certain of its subsidiaries, including Finco, filed voluntary petitions in the United States Bankruptcy Court for the Southern District of Texas (the “Bankruptcy Court”) seeking relief under chapter 11 of title 11 of the United States Code (the “Bankruptcy Code”). On September 4, 2020, the Debtors filed with the Bankruptcy Court the Joint Plan of Reorganization of Noble Corporation plc and its Debtor Affiliates, which was subsequently amended on October 8, 2020 and October 13, 2020 and modified on November 18, 2020 (as amended, modified or supplemented, the “Plan”), and the related disclosure statement (the “Disclosure Statement”). On September 24, 2020, six additional subsidiaries of Legacy Noble (together with Legacy Noble and its subsidiaries that filed on the Petition Date, as the context requires, the “Debtors”) filed voluntary petitions in the Bankruptcy Court. The chapter 11 proceedings were jointly administered under the caption Noble Corporation plc, et al. (Case No. 20-33826) (the “Chapter 11 Cases”). As a result of the filing of the Chapter 11 Cases, Legacy Noble’s Board of Directors determined to cancel Legacy Noble’s share ownership policy applicable to the officers and directors. Noble is currently considering an appropriate policy subsequent to its emergence from bankruptcy.
The filing of the Chapter 11 Cases constituted events of default that accelerated the Company’s obligations under the indentures governing our outstanding senior notes and under our 2017 Credit Facility (as defined herein). In addition, the unpaid principal and interest due under our then outstanding senior notes and 2017 Credit Facility became immediately due and payable. However, any efforts to enforce such payment obligations with respect to such senior notes and 2017 Credit Facility were automatically stayed as a result of the filing of the Chapter 11 Cases, and the creditors’ rights of enforcement were subject to the applicable provisions of the Bankruptcy Code. We elected not to make the semiannual interest payment due in respect of the Senior Notes due 2024 (the “2024 Notes”), which was due on July 15, 2020, and did not made any additional interest payments due on any senior notes through the Effective Date.
On the Petition Date, the Debtors entered into a Restructuring Support Agreement (together with all exhibits and schedules thereto, and as amended by the First Amendment thereto dated as of August 20, 2020, the “Restructuring Support Agreement”) with an ad hoc group of certain holders of approximately 70% of the aggregate outstanding principal amount of the Senior Notes due 2026 (the “Guaranteed Notes”) and an ad hoc group of certain holders of approximately 45% of the aggregate outstanding principal amount of our other then outstanding senior notes, taken as a whole (the “Legacy Notes”). Legacy Noble entered into a Backstop Commitment Agreement (the “Backstop Commitment Agreement”) with the backstop parties thereto (the “Backstop Parties”) on October 12, 2020, pursuant to which the issuance of the senior secured second lien notes (the “Second Lien Notes”) were fully backstopped by the Ad Hoc Guaranteed Group and the Ad Hoc Legacy Group (each as defined in the Restructuring Support Agreement). Participation in the rights offering of Second Lien Notes (the “Rights Offering”) was offered to the holders of the Guaranteed Notes and the Legacy Notes.On November 20, 2020, the Bankruptcy Court entered an order confirming the Plan. On the Effective Date, the Plan became effective in accordance with its terms and the Debtors emerged from the Chapter 11 Cases.
35


On the Effective Date, and pursuant to the terms of the Plan, the Company:
Appointed five new members to the Successor’s board of directors to replace all of the directors of the Predecessor, other than the director also serving as President and Chief Executive Officer, who was re-appointed pursuant to the Plan;
Terminated and cancelled all common stock and equity-based awards of Legacy Noble that were outstanding immediately prior to the Effective Date;
Transferred 31.7 million New Shares with a nominal value of $0.00001 per share to holders of the Guaranteed Notes in the cancellation of the Guaranteed Notes;
Transferred 2.1 million New Shares, approximately 8.3 million seven-year warrants with Black-Scholes protection (the “Tranche 1 Warrants”) with an exercise price of $19.27 and approximately 8.3 million seven-year warrants with Black-Scholes protection (the “Tranche 2 Warrants”) with an exercise price of $23.13 to holders of the Legacy Notes in cancellation of the Legacy Notes;
Issued approximately 7.7 million New Shares and Second Lien Notes to participants in the Rights Offering at an aggregate subscription price of $200 million;
Issued approximately 5.6 million New Shares to the Backstop Parties as Holdback Securities (as defined in the Backstop Commitment Agreement);
Issued approximately 1.7 million New Shares to the Backstop Parties in respect of their backstop commitment to subscribe for Unsubscribed Securities (as defined in the Backstop Commitment Agreement);
Issued approximately 1.2 million New Shares to the Backstop Parties in connection with the payment of the Backstop Premiums (as defined in the Backstop Commitment Agreement);
Issued 2.8 million five-year warrants with no Black-Sholes protection (the “Tranche 3 Warrants”) with an exercise price of $124.40 to the holders of Legacy Noble’s ordinary shares outstanding prior to the Effective Date;
Entered into a senior secured revolving credit agreement (the “Exit Credit Agreement”) providing for a $675.0 million senior secured revolving credit facility (with a $67.5 million sublimit for the issuance of letters of credit thereunder) (the “Exit Credit Facility”);
Entered into an exchange agreement with certain Backstop Parties which provided that, as soon as reasonably practicable after the Effective Date, the other parties to such agreement would deliver to the Company an aggregate of approximately 6.5 million New Shares issued pursuant to the Plan in exchange for the issuance of penny warrants to purchase up to approximately 6.5 million New Shares, with an exercise price of $0.01 per share (“Penny Warrants”) which were exchanged on a one-for-one basis for New Shares issued to certain initial holders of New Shares;
Entered into an indenture governing the Second Lien Notes;
Entered into a registration rights agreement with certain parties who received New Shares under the Plan (the “Equity Registration Rights Agreement”); and
Entered into a registration rights agreement with certain parties who received Second Lien Notes under the Plan.
Management Incentive Plan. The Plan contemplated that on or after the Effective Date, (i) the Company would adopt a long-term incentive plan and authorize and reserve 7.7 million New Shares for issuance pursuant to equity incentive awards to be granted under such plan, and (ii) the initial awards under such plan would consist of at least 40% of such shares and be made as soon as practicable after the Effective Date on the terms and conditions as determined by Noble’s Board of Directors; provided that at least 40% of such initial awards would be in the form of time-based vesting awards vesting over a period of no shorter than three years and no longer than four years. As contemplated by the Plan, on February 18, 2021, the Company adopted a long-term incentive plan and authorized and reserved 7.7 million New Shares for issuance pursuant to equity incentive awards to be granted under such plan.
Sources of Cash for Plan Distribution. All cash required for payments made by the Company under the Plan on the Effective Date was obtained from cash on hand, proceeds of the Rights Offering, and proceeds of the Exit Credit Facility.
Going Concern. Legacy Noble performed the required assessments in conjunction with the filing of its Form 10-Q for the three months ended March 31, 2020 and determined, at that time, that substantial doubt about its ability to continue as a going concern existed. Subsequent to emergence from the Chapter 11 Cases, Noble performed a reassessment and concluded there was no longer substantial doubt regarding the Noble’s ability to continue as a going concern one year from the date of filing the Noble's Form 10-K for the year ended December 31, 2020. This was primarily due to the cancellation of Legacy Noble’s outstanding debt obligations and increased liquidity with the Exit Credit Agreement (as defined herein). Management’s assessment was based on the relevant conditions that were known and reasonably knowable at the issuance date and included the Noble’s post-emergence financial condition and liquidity sources, forecasted future cash flows, contractual obligations and commitments and other conditions that could adversely affect the Noble’s ability to meet its obligations through one year from the issuance date of the Form 10-K.

Impairment
As more thoroughly described in Part II, Item 8, “Financial Statements and Supplementary Data, Note 6— Loss on Impairment” we evaluate our property and equipment for impairment whenever events orthere are changes in circumstances (including the decision to cold stack, retire or sell a rig) indicatefacts that suggest that the carrying amountvalue of anthe asset mayis not be recoverable. An impairment loss is recognized when and to the extent that an asset's carrying value exceeds its estimated fair value. As part of this analysis, we make assumptions and estimates regarding future market conditions. To the extent actual results do not meet our estimated assumptions for a given rig or piece of equipment, we may take an impairment loss in the future.
During the years ended December 31, 2017, 20162020, 2019 and 2015,2018, we recognized non-cash, before-tax impairment charges of $121.6$3.9 billion, $615.3 million $1.5 billion and $418.3$802.1 million, respectively, related to certain rigs and related capital spares. These impairments were driven by factors such as customer suspensions of drilling programs, contract cancellations, a further reduction in the number of new contract opportunities, capital spare equipment obsolescence, and our belief that a drilling unit is no longer marketable and is unlikely to return to service.
There can be no assurance that we will not have to take additional impairment charges in the future if current depressed market conditions persist.persist, or that we will be able to return cold stacked rigs to service in the time frame and at the reactivation costs or at the dayrates that we projected. It is reasonably possible that the estimate of undiscounted cash flows may change in the near term, resulting in the need to write down the affected assets to their corresponding estimated fair values.
Contract Drilling Services Backlog
We maintain a backlog of commitments for contract drilling services. Our contract drilling services backlog reflects estimated future revenues attributable to signed drilling contracts. While backlog did not include any letters of intent as of December 31, 2017,2020, in the past we have included in backlog certain letters of intent that we expect to result in binding drilling contracts.
We calculate backlog for any given unit and period by multiplying the full contractual operating dayrate for such unit by the number of days remaining in the period, and forinclude certain assumptions based on the threeterms of certain contractual arrangements, discussed in the notes to the table below. For the four rigs contracted with ShellExxon Mobil Corporation (“ExxonMobil”) mentioned below, we utilize the idle period and floor ratescurrent market rate, adjusted for a moderate discount rate, as described in Footnote (4)footnote (3) to the backlog table below. The reported contract drilling services backlog does not include amounts representing revenues for mobilization, demobilization and contract preparation, which are not expected to be significant to our contract drilling services revenues, amounts constituting reimbursables from customers or amounts attributable to uncommitted option periods under drilling contracts or letters of intent.

As previously reported, three of our long-term drilling contracts with Shell, the Noble Bully II, Noble Globetrotter I and Noble Globetrotter II
(2)Two of our long-term drilling contracts with Royal Dutch Shell plc (“Shell”), the Noble Globetrotter I and Noble Globetrotter II, contain a dayrate adjustment mechanism that utilizes an average of market rates that match a set of distinct technical attributes and is subject to a modest discount, beginning on the fifth-year anniversary of the contract and continuing every six months thereafter. On December 12, 2016, we amended those drilling contracts with Shell. As a result of the amendments, each of the contracts now has a contractual dayrate floor of $275,000 per day. Once the dayrate adjustment mechanism becomes effective and following any idle periods, the dayrate for these rigs will not be lower than the higher of (i) the contractual dayrate floor or (ii) the market rate as calculated under the adjustment mechanism. The impact to contract backlog from these amendments has a contractual dayrate floor. The contract amendments for the Noble Globetrotter I and Noble Globetrotter II provide a dayrate floor of $275,000 per day. The Noble Bully II contract contains a dayrate floor of $200,000 per day plus daily operating expenses. The amendment also provided Shell the right to idle the Noble Bully II for up to one year and Noble Globetrotter II for up to two years, each at a special stacking rate. Shell has exercised its right and, beginning late December 2016, we idled the Noble Globetrotter II at a rate of $185,000 per day. The Noble Bully II was idled at a rate of $200,000 per day, effective April 3, 2017. Once the dayrate adjustment mechanism becomes effective and following any idle periods, the dayrate for these rigs will not be lower than the higher of (i) the contractual dayrate floor or (ii) the market rate as calculated under the adjustment mechanism. The impact to contract backlog from these amendments has


been reflected in the table above and the backlog calculation assumes that, after any idle period at the contractual stacking rate, each rig will work at theirits respective dayrate floor for the remaining contract term.
(3)
Noble and a subsidiary of Shell are involved in joint ventures that own and operate both the Noble Bully I and Noble Bully II. Pursuant to these agreements, each party has an equal 50 percent share in both vessels. As of December 31, 2017, the combined amount of backlog for these rigs totaled $515.0 million, all of which is included in backlog. Noble’s proportional interest in the backlog for these rigs totaled $257.5 million.
(4)
Our Saudi Aramco contract rates for the Noble Joe Beall and Noble Gene House were adjusted downward in 2015. We expect the contract rates to be in the general range of the amended rates through the end of each respective contract. Backlog for these contracts has been prepared assuming the reduced rates apply for the remainder of the contract.
(5)
Some of our drilling contracts provide the customers with certain early termination rights and, in limited cases, those termination rights require minimal or no notice and financial penalties. As of February 20, 2018, no new notifications of contract terminations have been received.
(6)
Percent of available days committed is calculated by dividing the total number of days our rigs are operating under contract for such period by the product of the number of our rigs and the number of calendar days in such period.
(3)Noble entered into a multi-year Commercial Enabling Agreement (the “CEA”) with ExxonMobil in February 2020. Under the CEA, dayrates earned by each rig will be updated at least twice per year to the prevailing market rate, subject to a scale-based discount and a performance bonus that appropriately aligns the interests of Noble and ExxonMobil. Under the CEA, the table above includes awarded and remaining term of nine and a half years related to the Noble Tom Madden, six months to each of the Noble Bob Douglas and Noble Sam Croft, and one year to the Noble Don Taylor. Under the CEA, ExxonMobil may reassign term among rigs. The aforementioned additional backlog included in the table above was estimated using the current market rate, adjusted for a moderate discount rate.
(4)In April 2020, we received notice from Saudi Arabian Oil Company (“Saudi Aramco”) to suspend operations on the Noble Scott Marks for a period of up to 12 months. Beginning in early May 2020, we idled the Noble Scott Marks at a rate of $0 per day. The impact to contract backlog has been reflected in the table above and the backlog calculation assumes that, upon completion of the suspension period, the rig will resume operations at the contracted dayrate for the remaining contract term.
(5)Percent of available days committed is calculated by dividing the total number of days our rigs are operating under contract for such period by the product of the number of our rigs and the number of calendar days in such period.
The amount of actual revenues earned and the actual periods during which revenues are earned may be materially different than the backlog amounts and backlog periods presented in the table above due to various factors, including, but not limited to, the impact of the COVID-19 pandemic and related mitigation efforts on the demand for oil, current oversupply of oil, shipyard and maintenance projects, unplanned downtime, the operation of market benchmarks for dayrate resets, achievement of bonuses, weather conditions, reduced standby or mobilization rates and other factors that result in applicable dayrates lower than the full contractual operating dayrate. In addition, amounts included in the backlog may change because drilling contracts may be varied or modified by mutual consent or customers may exercise early termination rights contained in some of our drilling contracts or decline to enter into a drilling contract after executing a letter of intent. As a result, our backlog as of any particular date may not be indicative of our actual operating results for the periods for which the backlog is calculated. See Part I, Item 1A, “Risk Factors—Risks Related to Our Business and OperationsOur current backlog of contract drilling revenue may not be ultimately realized.”
For the year ended December 31, 2017, 2020, ExxonMobil, Shell, Saudi Aramcoand StatoilEquinor ASA represented approximately 57.744.2 percent, 18.626.3 percent, 17.0 percent and 14.33.6 percent of our backlog, respectively.respectively.

Results of Operations
2017During 2020, the global mitigation efforts associated with preventing the spread of COVID-19 and production level disputes among OPEC+ members had significant adverse consequences for the financial condition of our customers, and uncertainty about the financial viability of offshore projects, resulting in contract delays, suspension and terminations as well as customers seeking to re-negotiate contracts to secure price reductions. Preliminary demand data compiled by the International Energy Agency (the “IEA”) indicates global liquid fuels consumption declined by 9 million barrels per day in 2020, the largest decline in IEA data since 1980. As a consequence, throughout 2020, we were under pressure to reduce dayrates on existing contracts and idle or suspend existing operations, and market dayrates for new contracts were lower compared to the end of 2019.
2020 Compared to 20162019
Net loss from continuing operations attributable to Noble-UKNoble for the year ended December 31, 20172020 was $515.0 million,$4.0 billion, or $2.10$15.86 per diluted share, on operating revenues of $1.2$1.0 billion, compared to a net loss from continuing operations for the year ended December 31, 20162019 of $929.6$696.8 million, or $3.82$2.79 per diluted share, on operating revenues of $2.3$1.3 billion.
As a result of Noble-UKNoble conducting substantially all of its business through Noble-CaymanFinco and its subsidiaries, the financial position and results of operations for Noble-Cayman,Finco, and the reasons for material changes in the amount of revenue and expense items between December 31, 20172020 and December 31, 2016,2019, would be the same as the information presented below regarding Noble-UKNoble in all material respects, with the exception of operating income (loss). During the years ended December 31, 20172020 and 2016, Noble-Cayman's2019, Finco's operating loss was $37.9$100.6 million and $29.7$138.8 million lower, respectively, than that of Noble-UK.Noble. The operating loss difference is primarily a result of expenses related to ongoing litigation, administration, and other costsChapter 11 bankruptcy charges directly attributable to Noble-UKNoble for operations support and stewardship-related services.


In the years ended December 31, 2020 and 2019, Noble recorded a $15.0 million gain and a $100.0 million expense related to ongoing litigation, which was not recognized by Finco.
Key Operating Metrics
Operating results for our contract drilling services segment are dependent on three primary metrics: operating days, dayrates and operating costs. We also track rig utilization, which is a function of operating days and the number of rigs in our fleet. For more information on operating costs, see “—Contract Drilling Services,”Services” below.
The following table presents the average rig utilization, operating days and average dayrates for our rig fleet for the years ended December 31, 20172020 and 2016:2019:

Operating Revenues. The $1.0 billion decline$336.8 million decrease in contract drilling services revenues for the year ended December 31, 20172020 as compared to 2016the same period of 2019 was composed of an $851.6a $330.1 million declinedecrease due to a decreased number of operating days and a $6.7 million decrease from lower dayrates and a $183.6 million declinedayrates. The revenue decrease was due to fewer operating days. The contract drilling servicesdecreases in both floater fleet revenues decline was primarily due to our drillship and semisubmersible fleets, which experienced declines injackup fleet revenues of $975.7$235.8 million and $109.3$101.0 million, respectively, and was partially offset byrespectively.
The $235.8 million revenue increasesdecrease in our jackup fleet of $49.8 million.
The $975.7 million revenue decline in our drillshipfloater fleet for the year ended December 31, 2017 as compared2020 is attributable to 2016 consists of a $523.1$276.0 million decline from lower dayrates and $452.6 million declinedecrease mainly due to fewer operating days. The declinedays on two rigs, the Noble Bully II, which completed its contract in average dayrates waslate 2019, and the Noble Clyde Boudreaux, which completed its contract in the middle of 2020. These decreases were partially offset by an increase of $30.4 million primarily relateddue to the payment of the $393.0 million FCX Settlement in 2016. Of the decline in revenue attributable to operating days, $281.5 million is related to the Noble Bully I and Noble Bob Douglas operating for all of 2016, but being idle for the majority of 2017. The remainder of the decline in


operating days and the decline in average dayrates was attributable to the Noble Tom Madden andNoble Sam Croft whosereturning to service following its reactivation near the end of the three months ended March 31, 2019 and the Noble Don Taylor, which had time between contracts in 2019 related to contract preparation. Floater fleet revenue was also impacted by a decline in dayrates of $32.2 million as the legacy contract for the Noble Don Taylor and the legacy assignment for the Noble Globetrotter Iwere terminatedcompleted in May 2016.early 2019. These revenue reductions were partially offset by a $42.0 million increase in revenues associated with an increase in dayrates on various other rigs, including a $17.1 million increase in revenue on the Noble Sam Croft as a result of starting a new contract at a higher dayrate in 2020.
The $109.3$101.0 million revenue declinedecrease in our semisubmersiblejackup fleet for the year ended December 31, 2017 as compared2020 is attributable to 2016, consists of a $36.6$118.5 million decline from lower dayrates and a $72.7 million declinedecrease due to fewer operating days. The declinedays on the Noble Regina Allen mainly due to the rig relocating to Trinidad & Tobago from Canada to start a new contract, the Noble Sam Hartley which had downtime in both average dayrates and operating daysbetween contracts in 2020 during which it was warm-stacked, the Noble Scott Marks contract being suspended in May 2020 for a period of up to 12 months, the Noble Houston Colbert which was warm-stacked for five months in 2019 as compared to 2016eight months in 2020, the Noble Joe Beall which completed its final contract in early 2020 and was attributable tosubsequently sold later in 2020, and the Noble Sam Turner and the Noble Hans Deul which were warm-stacked in early 2020 after their contract completions for the Noble Clyde Boudreaux, Noble Jim Day,Noble Dave Beard, Noble Danny Adkins and Noble Amos Runner, none of which have returned to work since their respective contract completions.
The $49.8 million revenue This decrease was partially offset by an increase in our jackup fleet isrevenue of $34.0 million primarily attributabledue to an increase inincreased operating days on the Noble Mick O'Brien and Noble Regina Allen Tom Prosser, as well as the startupNoble Johnny Whitstine and the Noble Joe Knight being placed into service in 2019. Adjusting for the effect of operating days on the newbuild Noble Lloyd Noble.average dayrates, there was also a net decrease of revenue of $16.5 million due to a decline in dayrates across the jackup fleet.
Operating Costs and Expenses. Contract drilling services costs decreased $238.9$130.9 million for the year ended December 31, 20172020 as compared to 2016. Of the decrease, $179.0same period of 2019. The primary cost decreases were due to: (i) a $52.5 million wasdecrease due to rigs that operated during 2016 being idle during 2017. An additional $113.1had fewer operating days or were idled, (ii) a $37.3 million decrease across our active fleet in cost was2020 compared to 2019 mainly due to continuing cost control measures, yielding reductions in labor and training related costs of approximately $53.8 million, operations support costs of $29.7 million, repair and maintenance activity, transportation costs and personnel-related expenses, (iii) a $35.6 million decrease due to the retirement of $28.1the Noble Bully I, Noble Bully II, Noble Danny Adkins, Noble Joe Beall, Noble Jim Day and Noble Paul Romano during 2020 and (iv) a $23.4 million and rig mobilization costs of $3.0 million.decrease
40


in overhead across our fleet from lower personnel-related expenses in 2020 compared to 2019. These cost decreases were partially offset byby: (i) a $9.9 million increase in expenses due to the startupNoble Joe Knight commencing operations in September 2019. Due to the effects of the Noble Lloyd Noble,ongoing COVID-19 pandemic, we experienced a greater number of operating days for contracted rigs during 2017 and the write-off of a $14.4$9.8 million customer receivable during 2017.increase primarily in labor expenses across our fleet in 2020.

Depreciation and amortization decreased $63.2$66.1 million for the year ended December 31, 20172020 as compared to the same period of 2016.2019. The decline was due to the effect of rig retirementsimpairments recorded during 2019 and impairments2020.
Loss on Impairments. We recorded a loss on impairment of $3.9 billion for the year ended December 31, 2020 as compared to a loss on impairment of $615.3 million for the same period of 2019. We impaired the carrying value to estimated fair value for seven floaters and nine jackupsand certain capital spare equipment during 2016, partially offset by2020 and two floaters and certain capital spare equipment during 2019. We impaired the effectcarrying value to estimated fair value for the Noble Bully II during 2019, of the Noble Lloyd Noble being placed into service during November 2016.which $265.0 million was attributable to our former joint venture partner. For additional information, see Part II, Item 8, “Financial Statements and Supplementary Data, Note 6— Loss on Impairment.”
Other Income and Expenses
General and administrative expenses. General and administrative expenses increased $2.4 million during the year ended December 31, 2017 as compared to the same period of 2016, primarily due to higher professional fees.
Interest Expense, net of amount capitalized. Interest expense, net of amount capitalized, increased $69.1 million during the year ended December 31, 2017 as compared to 2016. This increase was primarily due to the interest incurred during 2017 on the senior notes issued in December 2016, the absence of capitalized interest during 2017 and an increase in interest rates on certain of our senior notes due to the downgrading of our credit rating. These increases were partially offset by the retirement of a portion of our Senior Notes due 2020 (the “2020 Notes”), Senior Notes due 2021 (the “2021 Notes”) and Senior Notes due 2022 (the “2022 Notes”) as a result of tender offers in 2016 and the maturity of our Senior Notes due 2017 (the “2017 Notes). For additional information see, Part II, Item 8, “Financial Statements and Supplementary Data, Note 7— Debt,” to our consolidated financial statements.
Income Tax Provision. Our income tax provision increased $151.8 million for the year ended December 31, 2017 as compared to the same period of 2016. The increase was primarily due to a $260.7 million non-cash discrete tax item resulting from a tax restructuring in 2017. The effect of this tax restructuring will be to lower current tax expense. This increase was partially offset by the tax effect of the FCX contract settlement of $27.2 million in 2016. Excluding the impact of these items, taxes decreased by $86.0 million as a result of lower pre-tax income in the current year, primarily from our geographical mix of pre-tax income.
2016 Compared to 2015
Net loss from continuing operations attributable to Noble-UK for the year ended December 31, 2016was $929.6 million, or $3.82 per diluted share, on operating revenues of $2.3 billion compared to net income from continuing operations for the year ended December 31, 2015 of $511.0 million, or 2.06 per diluted share, on operating revenues of $3.4 billion.
As a result of Noble-UK conducting all of its business through Noble-Cayman and its subsidiaries, the financial position and results of operations for Noble-Cayman, and the reasons for material changes in the amount of revenue and expense items between December 31, 2016 and December 31, 2015, would be the same as the information presented below regarding Noble-UK in all material respects, with the exception of operating income (loss). During the year ended December 31, 2016 and 2015, Noble-Cayman's operating loss was $29.7 million lower and operating income was $28.8 million higher, respectively, than that of Noble-UK. The operating income (loss) difference is primarily a result of administration and other costs directly attributable to Noble-UK for operations support and stewardship related services.



Key Operating Metrics
Operating results for our contract drilling services segment are dependent on three primary metrics: operating days, dayrates and operating costs. We also track rig utilization, which is a function of operating days and the number of rigs in our fleet. For more information on operating costs, see “—Contract Drilling Services,” below. The following table presents the average rig utilization, operating days and average dayrates for our rig fleet for the years ended December 31, 2016 and 2015:

Operating Revenues. The $1.0 billion decline in contract drilling services revenues for the year ended December 31, 2016 as compared to 2015 was composed of a $744.3 million decline due to fewer operating days and a $275.1 million decline from lower dayrates. The contract drilling services revenues decline was due to our semisubmersible, drillship and jackup fleets, which experienced declines in revenues of $669.0 million, $207.2 million and $143.2 million, respectively.
The $669.0 million revenue decline in our semsubmersible fleet consists of a $546.3 million decline due to fewer operating days and a $122.7 million decline from lower dayrates as compared to 2015. The declines in both operating days and average dayrates as compared to 2015 was attributable to contract completions for the Noble Jim Day, Noble Clyde Boudreaux, Noble Amos Runner, Noble Danny Adkins and Noble Dave Beard, which operated during the majority of 2015, but were not under contract in the majority of 2016.
The $207.2 million revenue decline in our drillship fleet consists of a $464.4 million decline due to fewer operating days, which was partially offset by a $257.2 million increase due to higher average dayrates as compared to 2015. The decline in operating days was primarily attributable to the retirement and subsequent sale of the Noble Discoverer, which operated in 2015 but did not operate during 2016. To a lesser extent, the decline in operating days was related to the contract cancellations of the Noble Sam Croft and Noble Tom Madden in 2016 and increased shipyard days on the Noble Globetrotter I in 2016. The revenue declines were partially offset by an increase in dayrate revenues primarily related to the occurrence of the $393.0 million FCX Settlement recognized in 2016.
The $143.2 million revenue decline in our semisubmersible fleet consists of a $143.1 million and $0.1 million decline due to a decrease in average dayrates and fewer operating days, respectively, as compared to 2015. The decrease in average dayrates was primarily attributable to the Noble Regina Allen, which was not operating under a contract during the majority of 2016 but operated during 2015, the retirement and subsequent sale of the Noble Charles Copeland, which operated during 2015, and the Noble Houston Colbert, which completed its contract during 2016. The revenue decreases were partially offset by the commencement of the newbuilds, the Noble Sam Hartley and Noble Lloyd Noble, which commenced operations in January 2016 and November 2016, respectively.
Operating Costs and Expenses. Contract drilling services costs decreased $353.1 million for the year ended December 31, 2016 as compared to 2015. Of the decrease, $254.5 million was due to rigs that operated during 2015, but were idle during 2016. An additional $95.2 million decline in cost was due to the retirement of the Noble Discoverer, Noble Charles Copeland and Noble Max Smith. An additional $62.1 million decline was due to continuing cost control measures. The cost control measures yielded reductions in repair and maintenance costs of $21.4 million, labor and training related costs of $19.9 million, operations support costs of approximately $8.1 million and other rig-related costs of $12.7 million. This was partially offset by a $58.7 million increase in cost related to rigs that had additional operating days during 2016, including two newbuild rigs, which commenced operations during 2016.
Loss on impairment during 2016 of $1.5 billion was recognized after we identified indicators that the carrying value of certain assets in our fleet may not be recoverable. As a result of our analysis, we determined that the carrying amounts of certain drilling units were impaired. In connection with our annual analysis, we impaired the carrying values for the Noble Amos Runner, Noble Clyde Boudreaux and Noble Dave Beard to the fair value. The impairment charge related to these units was approximately $1.0 billion. We also decided to retire from service our semisubmersible, the Noble Max Smith,which we sold during the fourth quarter of 2016 for approximately $1.2 million, and we recognized an impairment charge of approximately $164.8 million.
Also, in the fourth quarter of 2016, in connection with our impairment analysis, we concluded that the semisubmersible, the Noble Homer Ferrington and certain capital spare equipment would not be utilized in the foreseeable future and we recognized an impairment charge of approximately $120.1 million and $153.9 million, respectively. In the second quarter of 2016, we recognized a charge of approximately $16.6 million for the impairment of certain capital spare equipment based upon our decision to dispose of this equipment.
Other Income and Expenses
General and administrative expenses. Administrative Expenses. General and administrative expenses decreased $7.6 million during 2016 as compared to 2015, primarily as a result of decreased employee-related costs.
Interest Expense, net of amount capitalized. Interest expense, net of amount capitalized, increased $9.1 million during 2016 as compared to 2015. The increase was a result of a full period of interest in respect of the senior notes issued in March 2015, an increase in applicable interest rates on those senior notes due to the downgrading of our credit rating below investment grade during 2016 and lower capitalized interest in 2016 as compared to 2015, due to the completion of construction of two newbuild jackups, the Noble Sam Hartley and Noble Lloyd Noble, which commenced their respective contracts in January 2016 and November 2016. During 2016, we capitalized approximately 9 percent of total interest charges versus approximately 10 percent during the prior year. These expense increases were partially offset by the repayment of our maturing $350 million 3.45% Senior Notes due 2015 and our $300 million 3.05% Senior Notes due 2016 in August 2015 and March 2016, respectively, and the retirement of a portion of the 2020 Notes, the 2021 Notes and the 2022 Notes as a result of two different tender offers during 2016.


Interest Income and Other, Net. Interest income and other, net, decreased $36.3 million during 2016 as compared to 2015. The decrease is primarily the resultof the prior year including $30.0 million of interest income recognized in connection with the Noble Homer Ferringtonarbitration award and $5.0 million of interest received on aU.S. Internal Revenue Service (“IRS”)tax refund for the years 2006 and 2007.
Gain on extinguishment of debt, net. Gain on debt extinguishment increased $18.0$47.6 million during the year ended December 31, 20162020 as compared to 2015. This increase is due to the completionsame period of cash tender offers on our 2020 Notes, 2021 Notes and 2022 Notes during 2016, resulting in the purchase of $798.0 million of these senior notes for $774.0 million, plus accrued interest.
Income Tax Benefit (Provision). Our income tax provision decreased $268.0 million in 2016, of which $126.0 million related to the impact of impairment charges recognized in 2016, the Quadrant contract cancellation payment, the FCX Settlement, retirement of a portion of our 2020 Notes, 2021 Notes and 2022 Notes2019, primarily as a result of tender offers and discrete tax items in the current year and $27.0a reduction to Noble’s ongoing litigation charge of $53.5 million, related to the Noble Homer Ferrington arbitration award in 2015. Excluding the impact of these items, taxes decreased by $115.0 million as a result of lower pre-tax income partially offset by an increase in Finco’s litigation charge of $7.5 million.
Pre-Petition Charges. Noble incurred $14.4 million of pre-petition charges during the year ended December 31, 2020 as compared to no charges for the same period of 2019. These costs relate to attorneys’ and financial advisors’ fees and other professional fees incurred in connection with the Chapter 11 Cases, prior to the Petition Date.
Reorganization Items, Net. Noble incurred net charges of $23.9 million for reorganization items during the year ended December 31, 2020 as compared to no charges for the same period of 2019. Finco incurred net charges of $50.8 million for reorganization items during the year ended December 31, 2020 as compared to no charges for the same period of 2019. These costs relate to attorneys’ and financial advisors’ fees, write-off of deferred financing costs and debt discounts, revisions of estimated claims, adjustments to legal contingencies and other professional fees incurred in connection with the Chapter 11 Cases.
Interest Expense. Interest expense decreased $114.8 million during the year ended December 31, 2020 as compared to the same period of 2019. This decrease was primarily due to the Bankruptcy Court ordering a higher effectivestay on all interest expense starting on the Petition Date; therefore, we did not incur any interest expense after July 31, 2020 and the retirement of our 2015 Credit Facility in December 2019. For additional information, see Part II, Item 8, “Financial Statements and Supplementary Data, Note 7— Debt.”
Income Tax Benefit. Our income tax rate in the current year, primarily from our geographical mix of pre-tax income.

Liquidity and Capital Resources
As a result of the financial restructuring through the Chapter 11 Cases, Noble emerged with a new $675.0 million revolving credit facility and $216.0 million of Second Lien Notes (as defined herein). At emergence, Legacy Noble’s ordinary shares were cancelled and New Shares were issued to Legacy Noble’s former bondholders. Certain former bondholders and former equity holders of Legacy Noble were also issued warrants to purchase shares of the Company.

The Exit Credit Facility matures on July 31, 2025. Subject to the satisfaction of certain conditions, Finco may from time to time designate one or more of Finco’s other wholly-owned subsidiaries as comparedadditional borrowers under the Exit Credit Agreement (collectively with Finco and NIFCO, the “Borrowers”). As of the Effective Date, $177.5 million of loans were outstanding, and $8.8 million of letters of credit were issued, under the Exit Credit Facility.
All obligations of the Borrowers under the Exit Credit Agreement, certain cash management obligations and certain swap obligations are unconditionally guaranteed, on a joint and several basis, by Finco and certain of its direct and indirect subsidiaries (collectively with the Borrowers, the “Credit Parties”), including a guarantee by each Borrower of the obligations of each other Borrower under the Exit Credit Agreement. All such obligations, including the guarantees of the Exit Credit Facility, are secured by senior priority liens on substantially all assets of, and the equity interests in, each Credit Party, including all of the rigs owned by the Company as of the Effective Date or acquired thereafter and certain assets related thereto, in each case, subject to $669.9certain exceptions and limitations described in the Exit Credit Agreement.
The loans outstanding under the Exit Credit Facility bear interest at a rate per annum equal to the applicable margin plus, at Finco’s option, either: (i) the reserve-adjusted LIBOR or (ii) a base rate, determined as the greatest of (x) the prime loan rate as published in the Wall Street Journal, (y) the federal funds effective rate plus 1⁄2 of 1%, and (z) the reserve-adjusted one-month LIBOR plus 1%. The applicable margin is initially 4.75% per annum for LIBOR loans and 3.75% per annum for base rate loans and will be increased by 50 basis points after July 31, 2024, and may be increased by an additional 50 basis points under certain conditions described in the Exit Credit Agreement.
The Borrowers are required to pay a quarterly commitment fee to each lender under the Exit Credit Agreement, which accrues at a rate per annum equal to 0.50% on the average daily unused portion of such lender’s commitments under the Exit Credit Facility. The Borrowers are also required to pay customary letter of credit and fronting fees.
Borrowings under the Exit Credit Agreement may be used for working capital and other general corporate purposes. Availability of borrowings under the Exit Credit Agreement is subject to the satisfaction of certain conditions, including restrictions on borrowings if, after giving effect to any such borrowings and the application of the proceeds thereof, (i) the aggregate amount of Available Cash (as defined in the Exit Credit Agreement) would exceed $100 million, (ii) the Consolidated First Lien Net Leverage Ratio (as defined in the Exit Credit Agreement) would be greater than 5.50 to 1.00 and the aggregate principal amount outstanding under the Exit Credit Facility would exceed $610 million, or (iii) the Asset Coverage Ratio (as described below) would be less than 2.00 to 1.00.
Mandatory prepayments and, under certain circumstances, commitment reductions are required under the Exit Credit Facility in connection with (i) certain asset sales, asset swaps and events of loss (subject to reinvestment rights if no event of default exists) and (ii) certain debt issuances.

Second Lien Notes Indenture
On the Effective Date, pursuant to the Backstop Commitment Agreement and in accordance with the Plan, Noble and Finco consummated the Rights Offering of Second Lien Notes and associated New Shares at an aggregate subscription price of $200 million.
On the Effective Date, Finco issued an aggregate principal amount of $216 million of Second Lien Notes, which includes the aggregate subscription price of $200.0 million plus a backstop fee of $16.0 million which was paid in kind. The Second Lien Notes mature on February 15, 2028.The Second Lien Notes are fully and unconditionally guaranteed, jointly and severally, on a senior secured second-priority basis, by the direct and indirect subsidiaries of Finco that are Credit Parties under the Exit Credit Facility. The Second Lien Notes and such guarantees are secured by senior priority liens on the assets subject to liens securing the Exit Credit Facility, including the equity interests in Finco and each guarantor of the Second Lien Notes, all of the rigs owned by the Company as of the Effective Date or acquired thereafter, certain assets related thereto, and substantially all other assets of Finco and such guarantors, in each case, subject to certain exceptions and limitations.
Interest on the Second Lien Notes accrues, at Finco’s option, at a rate of: (i) 11% per annum, payable in cash; (ii) 13% per annum, with 50% of such interest to be payable in cash and 50% of such interest to be payable by issuing additional Second Lien Notes (“PIK Notes”); or (iii) 15% per annum, with the entirety of such interest to be payable by issuing PIK Notes. Finco shall pay interest semi-annually in arrears on February 15 and August 15 of each year, commencing August 15, 2021.
On or after February 15, 2024, Finco may redeem all or part of the Second Lien Notes at fixed redemption prices (expressed as percentages of the principal amount), plus accrued and unpaid interest, if any, to, but excluding, the redemption date. Finco may also redeem the Second Lien Notes, in whole or in part, at any time and from time to time on or before February 14, 2025 at a redemption price equal to 106% of the principal amount plus accrued and unpaid interest, if any, to, but excluding, the applicable redemption date, plus a “make-whole” premium. Notwithstanding the foregoing, if a Change of Control (as defined in the Second Lien Notes Indenture) occurs prior to (but not including) February 15, 2024, then, within 120 days of such Change of Control, Finco may elect to purchase all remaining outstanding Second Lien Notes at a redemption price equal to 106% of the principal amount, plus accrued and unpaid interest, if any, to, but excluding, the applicable redemption date.
The Second Lien Notes contain covenants and events of default that the Company considers customary for $300.0 millionnotes of this type.
Sources and dividends paid to noncontrolling interestsUses of approximately $56.9 million.Cash
Our principal sourcesources of capital in the current period was2020 were cash generated from operating activities, funding from our 2017 Credit Facility and cash on hand.the CARES Act. Cash on hand during the current period2020 was primarily used for the following:
normal recurring operating expenses;
repayment offees and expenses related to the 2017 Notes;Chapter 11 Cases; and
capital expenditures.
Our currently anticipated cash flow needs, both in the short-term and long-term, may include the following:
normal recurring operating expenses;
planned and discretionary capital expenditures; and
repaymentrepayments of debt and interest.
We currently expect to fund these cash flow needs with cash generated by our operations, cash on hand, borrowings under our Exit Credit Facilities (as defined below)Facility and potential issuances of equity or long-term debt. However, to adequately cover our expected cash flow needs, we may require capital in excess
On March 27, 2020, the 45th President of the United States signed the CARES Act into law. The CARES Act makes significant changes to various areas of US federal income tax law by, among other things, allowing a five-year carryback period for 2018, 2019 and 2020 NOLs, accelerating the realization of remaining alternative minimum tax credits, and increasing the interest expense limitation under Section 163(j) for years 2019 and 2020. The Company recognized an income tax benefit of $39.0 million as a result of the application of the CARES Act in its 2020 financial statements. Such $39.0 million tax benefit was comprised primarily of a current income tax receivable of $151.4 million, partially offset by non-cash deferred tax expense of $112.4 million related to NOL utilization. As of December 31, 2020, we had
43


received $134.0 million of the income tax receivable related to the CARES Act, along with an additional receipt of $4.4 million of related interest.
Net cash provided by operating activities was $273.2 million for the year ended December 31, 2020 as compared to $186.8 million for the year ended December 31, 2019. The increase in net cash provided by operating activities for the year ended December 31, 2020 was primarily attributable to $151.2 million in tax refunds received offset by a reduction in cash flows from operating activity. We had working capital of $383.9 million and negative working capital of $94.8 million at December 31, 2020 and December 31, 2019, respectively.
Net cash used in investing activities for the year ended December 31, 2020 was $121.5 million as compared to $256.0 million for the year ended December 31, 2019. The variance primarily relates to the purchase and preparation of the Noble Joe Knight and the preparation of the Noble Johnny Whitstine to commence operations for their contracts in the fourth quarter and the second quarter of 2019, respectively.
Net cash provided by financing activities for the year ended December 31, 2020 was $107.4 million as compared to net cash used in financing activities of $200.7 million for the year ended December 31, 2019. The variance primarily relates to higher net borrowings of $108.9 million in the current period as compared to net repayments of only $65.0 million in the year ended December 31, 2019 and the $106.7 million purchase of Shell's non-controlling interest in the Bully I and Bully II joint ventures in the year ended December 31, 2019.
In March 2019, we completed cash tender offers for our Senior Notes due 2020 (the “2020 Notes”), our Senior Notes due 2021 (the “2021 Notes”), our Senior Notes due 2022 (the “2022 Notes”)and the 2024 Notes. Pursuant to such tender offers, we purchased $440.9 million aggregate principal amount available fromof these sources,senior notes for $400.0 million, plus accrued interest, using borrowings under the 2015 Credit Facility (as defined herein) and we may seek additional sources of liquidity and/or delay or cancel certain discretionary capital expenditures or other payments as necessary.cash on hand.
At December 31, 2017,2020, we had a total contractcontract drilling services backlog of approximately $3.0 billion. Our backlog as of December 31, 2017$1.6 billion, which includes a commitment of 4467.0 percent of availableavailable days for 2018.2021.

Capital expenditures including capitalized interest, totaled $111.1$148.2 million, $659.9$306.4 million and $422.5$281.3 million for the years ended December 31, 2017, 20162020, 2019 and 20152018, respectively. Capital expenditures during 20172020 consisted of the following:
$58.665.8 million for sustaining capital and upgrades and replacements to drilling equipment;capital;
$39.323.9 million in major projects, including subsea and other related projects; and
$13.258.5 million in subsea related expenditures.for rebillable capital modifications.
Our total capital expenditure estimate for 20182021 is expected to range between $170.0 million and $190.0 million, of which approximately $148.0$80.0 to $90.0 million which is currently anticipated to be spent as follows:
$83.0 million for sustaining capital; and


$65.0 million for major projects, subsea related expenditures and upgrades and replacements to drilling equipment.capital.
From time to time we consider possible projects that would require expenditures that are not included in our capital budget, and such unbudgeted expenditures could be significant. In addition, while liquidity and preservation of capital remains our top priority, we will continue to evaluate acquisitions of drilling units from time to time. Other factors that could cause actual capital expenditures to materially exceed plan include delays and cost overruns in shipyards (including costs attributable to labor shortages), shortages of equipment, latent damage or deterioration to hull, equipment and machinery in excess of engineering estimates and assumptions, changes in governmental regulations and requirements and changes in design criteria or specifications during repair or construction.
Dividends
The declaration and payment of dividends require the authorization of the Board of Directors of Noble-UK, provided that such dividends on issued share capital may be paid only out of Noble-UK’s “distributable reserves” on its statutory balance sheet in accordance with UK laws. Therefore, Noble-UK is not permitted to pay dividends out of share capital, which includes share premiums. The resumption of the payment of future dividends will depend on our results of operations, financial condition, cash requirements, future business prospects, contractual restrictions and other factors deemed relevant by our Board of Directors.
Share Repurchases
The Company is only permitted to purchase its own shares by way of an “off-market purchase” in a plan approved by shareholders. In December 2014, we received shareholder approval to repurchase up to 37 million ordinary shares, or approximately 15 percent of our outstanding ordinary shares at the time of the shareholder approval. The authority to make such repurchases expired at the end of the Company’s 2016 annual general meeting of shareholders, which was held on April 22, 2016. During 2015, we repurchased 6.2 million of our ordinary shares covered by this authorization at an average price of $16.10 per share, excluding commissions and stamp tax, for a total cost of approximately $100.6 million. All shares repurchased were made in the open market pursuant to the share repurchase program discussed above, and all shares repurchased were immediately canceled. During the years ended December 31, 2017 and 2016, we did not repurchase any shares of our shares.
Credit Facilities and Senior Unsecured Notes
2015 Credit Facility
At December 31, 2017, we had a five-year $2.4 billion senior unsecured credit facility that matures in January 2020 and which is guaranteed by our indirect, wholly owned subsidiaries, Noble Holding (U.S.) LLC (“NHUS”) and Noble Holding International Limited (“NHIL”) (the “2015 Credit Facility”). The 2015 Credit Facility also provided us with the ability to issue up to $500.0 million in letters of credit. The issuance of letters of credit under the facility reduces the amount available for borrowing. At December 31, 2017, we had no borrowings outstanding or letters of credit issued under our 2015 Credit Facility.
On December 19, 2017, we entered into the First Amendment and Consent and Successor Agent Agreement, (the “Amendment”) amending the 2015 Credit Facility. Upon certain conditions, including the entering into of the Company's 2017 Credit Facility (as defined below), the Amendment provides for, on or after January 3, 2018, among other things (i) a reduction in the aggregate principal amount of commitments under the 2015 Credit Facility to $300.0 million and (ii) the reduction of the 2015 Credit Facility's letter of credit subfacility to zero dollars. The maturity of the 2015 Credit Facility remains January 2020.Pre-emergence Debt
2017 Credit Facility
OnIn December 21, 2017, Noble Cayman Limited, a Cayman Islands company and a wholly-owned indirect subsidiary of Noble-Cayman (“NCL”);Finco; Noble International Finance Company, (“NIFCO“);a Cayman Islands company and a wholly-owned indirect subsidiary of Finco; and Noble Holding UK Limited, a company incorporated under the laws of England and Wales and a wholly-owned direct subsidiary of Noble-UKLegacy Noble (“NHUK”), as parent guarantor, entered into a new senior unsecured credit agreement (the(as amended, the “2017 Credit Facility” and together with the 2015). In July 2019, we executed a first amendment to our 2017 Credit Facility, which, among other things, reduced the “Credit Facilities“). The maximum aggregate amount of borrowings undercommitments thereunder from $1.5 billion to $1.3 billion. As a result of such reduction in the maximum aggregate amount of commitments, we recognized a net loss of approximately $0.7 million in the year ended December 31, 2019.
Prior to the filing of the Chapter 11 Cases, the 2017 Credit Facility of $1.5 billion becamewas scheduled to mature in January 2023. Borrowings were available on January 3, 2018 upon the effectiveness of the commitment reduction under the 2015 Credit Facility. Borrowings under the 2017 Credit Facility are subject to certain conditions precedent, including that there be no unused commitments to advance loans under the 2015 Credit Facility.for working capital and other general corporate purposes. The 2017 Credit Facility providesprovided for a letter of credit subfacility currentlysub-facility in the amount of $15.0 million, with the ability to increase such amount up to $500.0 million. Borrowings may be used for working capital and other general corporate purposes.million with the approval of the lenders. The 2017 Credit Facility has an initial maturity of up to five years from the date on which the borrowings became available, or January 3, 2023. At December 31, 2017, we had no borrowings outstanding or letters of credit issued under the 2017 Credit Facility.

Both of our Credit Facilities have provisions which varythat varied the applicable interest rates for borrowings based upon our debt ratings. We also pay a facility fee under each of the Credit Facilities on the daily unused amount of the underlying commitment which varies depending on our


credit ratings. At December 31, 2017, the interest rates in effect under our Credit Facilities are the highest permitted interest rates under those agreements.
Debt Issuances
On January 31, 2018, we issued and sold $750.0 million aggregate principal amount of our Senior Notes due 2026 (the “2026 Notes”), through our indirect wholly-owned subsidiary, NHIL. The 2026 Notes are issued under an indenture by and among NHIL, Noble-Cayman, certain other subsidiaries of Noble-Cayman named therein (the “Subsidiary Guarantors”), and are guaranteed by Noble-Cayman and the Guarantor Subsidiaries. The proceeds of the offering of approximately $737.0 million, after estimated expenses, were used to retire a portion of our near-term senior notes in a related tender offer.
The 2026 Notes are redeemable, in whole or in part, prior to February 1, 2021, at a redemption price equal to 100% of the aggregate principal amount of the 2026 Notes being redeemed, plus a make-whole premium. The 2026 Notes are redeemable prior to February 1, 2021, at a redemption price equal to 40% of the aggregate principal amount in the event of an equity offering. Further, the 2026 Notes may be redeemed in whole as a result of changes in tax law. On or after February 1, 2021, we may redeem all or any portion of the 2026 Notes at various redemption prices set forth in the indenture.
Upon (i) the occurrence of a change of control and (ii) a downgrade of the rating of the 2026 Notes within 60 days after the change of control by at least two of Moody’s Investors Service, Inc., Standard & Poor’s Financial Services LLC or Fitch Ratings Inc., we will be required to make an offer to repurchase all outstanding 2026 Notes at a price in cash equal to 101% of the aggregate principal amount of the 2026 Notes repurchased, plus any accrued and unpaid interest to, but excluding, the repurchase date.
The indenture for the 2026 Notes contains certain covenants and restrictions, including, among others, restrictions on our and our subsidiaries’ ability, as applicable, to create certain liens, enter into certain sale and leaseback transactions, merge or consolidate with another entity, sell all or substantially all of their assets and allow our subsidiaries to incur certain additional indebtedness. Additionally, the Subsidiary Guarantors must own, directly or indirectly, (i) assets comprising at least 85%of the revenue of Noble-Cayman and its subsidiaries on a consolidated basis and (ii) jackups, semisubmersibles, drillships, submersibles or other mobile offshore drilling units of material importance, the combined book value of which comprises at least 85% of the combined book value of all such assets of Noble-Cayman and its subsidiaries on a consolidated basis, in each case, with respect to the most recently completed fiscal year.
In December 2016, we issued $1.0 billion aggregate principal amount of Senior Notes due 2024 (the “2024 Notes”), which we issued through our indirect wholly-owned subsidiary, NHIL. The net proceeds of approximately $967.6 million, after estimated expenses, were primarily used to retire a portion of our near-term senior notes in a related tender offer and the remaining portion was used for general corporate purposes.
Senior Notes Interest Rate Adjustments
During 2016 and 2017, we experienced debt rating downgrades by Moody’s Investors Service and S&P Global Ratings, which reduced our debt ratings significantly below investment grade. As a result of these downgrades, we experienced interest rate increases during 2016 and 2017 on the 2018 Notes, the 2025 Notes and the 2045 Notes, all of which are subject to provisions that vary the applicable interest rates based on our debt rating. On October 18, 2017, S&P Global Ratings further reduced our debt rating, which will increase the interest rates on the 2025 Notes and the 2045 Notes to 7.95% and 8.95%, respectively, beginning in April 2018. Once the new interest rates take effect in April 2018, these senior notes will have reached the contractually-defined maximum interest rate set for each rating agency and no further interest rate increase will occur
Our other outstanding senior notes, including the 2024 Notes issued in December 2016 and the 2026 Notes issued in January 2018, do not contain provisions varying applicable interest rates based upon our credit ratings.
Debt Tender Offers and Repayments
In January 2018, we commenced cash tender offers for our 2018 Notes, 2019 Notes, 2020 Notes, 2021 Notes, 2022 Notes and 2024 Notes. In February 2018, we purchased $754.2 million aggregate principal amount of these senior notes for $750.0 million, plus accrued interest, using the net proceeds of the 2026 Notes issuance in January 2018 and cash on hand. As a result of these tender offers, we recognized a net loss of approximately $2.0 million. In February 2018, we completed an optional redemption of our remaining 2019 Notes. Both the tender offers and redemption are described further in “Note 19— Subsequent Events.”
In March 2017, we repaid our 2017 Notes using cash on hand. We anticipate using cash on hand to repay the outstanding balance of our 2018 Notes, maturing in March 2018.
In December 2016, we commenced cash tender offers for our 2020 Notes, 2021 Notes and 2022 Notes. On December 28, 2016, we purchased $762.3 million of these senior notes for $750.0 million, plus accrued interest, using a portion of the net proceeds of the $1.0 billion 2024 Notes issuance in December 2016. In December 2016, as a result of these tender offers, we recognized a net gain of approximately $6.7 million.


In March 2016, we commenced cash tender offers for our 2020 Notes and our 2021 Notes. On April 1, 2016, we purchased $36.0 million of these senior notes for $24.0 million, plus accrued interest, using cash on hand. In April 2016, as a result of these tender offers, we recognized a net gain of approximately $11.1 million.
Covenants
The 2015 Credit Facility is guaranteed by NHUS and NHIL. The 2015 Credit Facility contains a covenant that limits our ratio of debt to total tangible capitalization, as defined in the 2015 Credit Facility, to 0.60. At December 31, 2017, our ratio of debt to tangible capitalization was approximately 0.43.
The 2017 Credit Facility contains certain financial covenants (as defined in the 2017 Credit Facility) applicable to NHUK and its subsidiaries, including (i) a covenant restricting debt to total tangible capitalization to not greater than 55% at the end of each fiscal quarter, (ii) a minimum Liquidity requirement of $300.0 million, (iii) a covenant that, beginning with the fiscal quarter ending March 31, 2018, the ratio of the Rig Value of Marketed Rigs to the sum of commitmentsBorrowings under the 2017 Credit Facility bore interest at LIBOR plus indebtedness for borrowed money of the borrowers and guarantors, in each case, that directly own Marketed Rigs, is not less than 3:00 to 1:00 at the end of each fiscal quarter and (iv) a covenant that, beginning with the fiscal quarter ending March 31, 2018, the ratio of (A) the Rig Value of the Closing Date Rigs that are directly wholly owned by the borrowers and guarantors to (B) the Rig Value of the Closing Date Rigs owned byan applicable margin. NHUK subsidiaries of NHUK and certain local content affiliates, is not less than 80% at the end of each fiscal quarter (such covenants described in (iii) and (iv) of this paragraph, the “Guarantor Ratio Covenants”). The 2017 Credit Facility also includes restrictions on 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 2017 Credit Facility) would exceed $200.0 million.
NHUK has guaranteed the obligations of the borrowers under the 2017 Credit Facility. Certain otherIn addition, certain indirect subsidiaries of Noble-UK will be required from time to time to guaranteeLegacy Noble that owned rigs were guarantors under the obligations of the borrowers2017 Credit Facility.
In April 2020, we borrowed $100.0 million under the 2017 Credit Facility in order maintain compliance withto pay down our indebtedness under the Guarantor Ratio Covenants.
The 2017 Credit Facility contains additional covenants generally applicable to NHUK and its subsidiaries that NCL considers usual and customary for an agreementSeller Loans (as defined herein) as further described below. At December 31, 2020, we had $545.0 million of this type, including compliance with laws (including environmental laws, ERISA and anti-corruption and sanctions laws), delivery of quarterly and annual financial statements, maintenance and operation of property, restrictions on the incurrence of liens and indebtedness, mergers and other fundamental changes, restricted payments, repurchases and redemptions of indebtedness with maturities outside of the maturity ofborrowings outstanding under the 2017 Credit Facility, sale and leaseback transactions and transactions with affiliates.

The filing of the occurrence ofChapter 11 Cases constituted events of default that NCL considers usual and customary for an agreement of this type.
In addition toaccelerated the covenants from the Credit Facilities noted above,Company’s obligations under the indentures governing our outstanding senior unsecured notes contain covenants that place restrictions on certain merger and consolidation transactions, unless we are under our 2017 Credit Facility. In addition, the surviving entity orunpaid principal and interest due under our indentures and the other party assumes2017 Credit Facility became immediately due and payable. However, any efforts to enforce such payment obligations with respect to our senior notes and 2017 Credit Facility were automatically stayed as a result of the filing of the Chapter 11 Cases, and the creditors’ rights of enforcement were subject to the applicable provisions of the Bankruptcy Code. See “Note 1— Organization and Basis of Presentation” to our consolidated financial statements for additional information.
On the Effective Date, all outstanding obligations under the indenture,2017 Credit Facility were terminated and the holders of claims under the 2017 Credit Facility had such obligations refinanced through the Exit Credit Facility. On the Effective Date, all liens and security interests granted to secure such obligations were terminated and are of no further force and effect.
2015 Credit Facility
Effective January 2018, in connection with entering into the 2017 Credit Facility, we amended our $300.0 million senior unsecured credit facility that would have matured in January 2020 and was guaranteed by our indirect, wholly-owned subsidiaries, Noble Holding (U.S.) LLC and Noble Holding International Limited (“NHIL”), a finance subsidiary of Finco, (as amended, the “2015 Credit Facility”). As a result of the 2015 Credit Facility's reduction in the aggregate principal amount of commitments, we recognized a net loss of approximately $2.3 million in the year ended December 31, 2018. On December 20, 2019, we repaid $300.0 million of outstanding borrowings and terminated the 2015 Credit Facility.
Seller Loans
In February 2019, we purchased the Noble Joe Knight for $83.8 million with a $53.6 million seller-financed secured loan (the “2019 Seller Loan”). The 2019 Seller Loan had a term of four years and required a 5% principal payment at the end of the third year with the remaining 95% of the principal due at the end of the term. The 2019 Seller Loan bore a cash interest rate of 4.25% and the equivalent of a 1.25% interest rate paid-in-kind over the four-year term of the 2019 Seller Loan. Based on the ability to sell or transfer all or substantially all of our assets. In addition, there are restrictions on incurring debt or assuming certain liens and on entering into sale and lease-back transactions. The indenture for the 2026 Notes that we issued in January 2018 places more limitations on us and our subsidiaries than our other senior note indentures. See “—Debt Issuances” above.
At December 31, 2017, and February 20, 2018, we were in compliance with allterms of the debt covenants under our Credit Facilities2019 Seller Loan, the 1.25% paid-in-kind interest rate was accelerated into the first year, resulting in an overall first year interest rate of 8.91%, of which only 4.25% was payable in cash. Thereafter, the paid-in-kind interest ended and senior notes. We continually monitor compliance with the covenants under our Credit Facilities and senior notes and expect to remain in compliance duringcash interest rate of 4.25% was payable for the remainder of 2018.the term.

In September 2018, we purchased the Noble Johnny Whitstine for $93.8 million with a $60.0 million seller-financed secured loan (the “2018 Seller Loan” and, together with the 2019 Seller Loan, the “Seller Loans”). The 2018 Seller Loan had a term of four years and required a 5% principal payment at the end of the third year with the remaining 95% of the principal due at the end of the term. The 2018 Seller Loan bore a cash interest rate of 4.25% and the equivalent of a 1.25% interest rate paid-in-kind over the four-year term of the 2018 Seller Loan. Based on the terms of the 2018 Seller Loan, the 1.25% paid-in-kind interest rate was accelerated into the first year, resulting in an overall first year interest rate of 8.91%, of which only 4.25% was payable in cash. Thereafter, the paid-in-kind interest ended and the cash interest rate of 4.25% was payable for the remainder of the term.

Both of the Seller Loans were guaranteed by Finco and each was secured by a mortgage on the applicable rig and by the pledge of the shares of the applicable single-purpose entity that owned the relevant rig. Each Seller Loan contained a debt to total capitalization ratio requirement that such ratio not exceed 0.55 at the end of each fiscal quarter, a $300.0 million minimum liquidity financial covenant and an asset and revenue covenant substantially similar to the Guaranteed Notes, as well as other covenants and provisions customarily found in secured transactions, including a cross default provision. Each Seller Loan required immediate repayment on the occurrence of certain events, including the termination of the drilling contract associated with the relevant rig or circumstances in connection with a material adverse effect.
In April 2020, the Company agreed with the lender under the Seller Loans to pay off 85% of the outstanding principal amount of the Seller Loans in exchange for a discount to the outstanding loan balance. On April 20, 2020, the Company made a payment of $48.1 million under the 2019 Seller Loan and $53.6 million under the 2018 Seller Loan, and, upon the lender’s receipt of such payment, interest ceased accruing, and the financial covenants set forth in the agreements relating to the Seller Loans ceased to apply. On July 20, 2020, at the conclusion of the 90-day period following the payment date, all outstanding amounts were reduced to zero, all security was released, and the Seller Loans were terminated.
As a result of the early repayment of the Seller Loans and the conclusion of the 90-day period following the payment date, we recognized gains of approximately $17.3 million in the year ended December 31, 2020.

Senior Notes
In March 2019, we completed cash tender offers for the 2020 Notes, the 2021 Notes, the 2022 Notes, and the 2024 Notes. Pursuant to such tender offers, we purchased $440.9 million aggregate principal amount of these senior notes for $400.0 million, plus accrued interest, using cash on hand and borrowings under the 2015 Credit Facility. As a result of these transactions, we recognized a net gain of approximately $31.3 million.
On the Effective Date, in accordance with the Plan, all outstanding obligations under our senior notes were cancelled and the indentures governing such obligations were cancelled, except to the limited extent expressly set forth in the Plan.
Share Capital
The declaration and payment of dividends required the authorization of the Board of Directors of Legacy Noble, provided that such dividends on issued share capital may be paid only out of Legacy Noble’s “distributable reserves” on its statutory balance sheet in accordance with UK law. Therefore, Legacy Noble was not permitted to pay dividends out of share capital, which includes share premium. Legacy Noble had not paid dividends since the third quarter of 2016. The payment of future dividends will depend on our results of operations, financial condition, cash requirements, future business prospects, contractual and indenture restrictions and other factors deemed relevant by our Board of Directors; however, at this time, we do not expect to pay any dividends in the foreseeable future.
At Legacy Noble’s 2020 Annual General Meeting, Legacy Noble’s shareholders authorized its Board of Directors to increase share capital through the issuance of up to approximately 8.7 million ordinary shares (at then current nominal value of $0.01 per share). That authority to allot shares has expired on the Effective Date. Other than shares issued to Legacy Noble’s directors under the Noble Corporation 2017 Director Omnibus Plan, the authority was not used to allot shares during the year ended December 31, 2020. Pursuant to the Memorandum of Association of Noble Corporation, the share capital of Noble is $6,000 divided into 500,000,000 ordinary shares of a par value of $0.00001 each and 100,000,000 shares of a par value of $0.00001, each of such class or classes having the rights as the Board may determine from time to time.
In accordance with the Plan, all agreements, instruments and other documents evidencing, relating to or otherwise connected with any of Legacy Noble’s equity interests outstanding prior to the Effective Date, including all equity-based awards, were cancelled and all such equity interests have no further force or effect after the Effective Date. Pursuant to the Plan, the holders of Legacy Noble’s ordinary shares, par value $0.01 per share, outstanding prior to the Effective Date received their pro rata share of the Tranche 3 Warrants to acquire New Shares.
Share Repurchases
Under UK law, Legacy Noble was only permitted to purchase its own shares by way of an “off-market purchase” in a plan approved by shareholders. We did not have shareholder authority to repurchase shares of Legacy Noble and there is currently no share repurchase plan in place for the Successor. During the years ended December 31, 2020, 2019 and 2018, we did not repurchase any of our shares.

These obligations include letters of credit that guarantee our performance as it relates to our drilling contracts, tax and other obligations in various jurisdictions. These letters of credit obligations are not normally called, as we typically comply with the underlying performance requirement.

NHIL is a finance subsidiary of Finco and prior to our emergence from the Chapter 11 Cases on the Effective Date, had issued the following registered securities, which, together with the indentures governing such registered securities, were cancelled on the Effective Date in accordance with the Plan: the 2020 Notes, the 2021 Notes, the 2022 Notes, the 2024 Notes, the Senior Notes due 2025, the Senior Notes due 2040, the Senior Notes due 2041, the Senior Notes due 2042 and the Senior Notes due 2045. Finco had fully and unconditionally guaranteed these registered securities and no other subsidiary of Finco had guaranteed these registered securities. Due to this fact pattern, separate financial information about NHIL and Finco will not be disclosed.
Critical Accounting Policies
We consider the following to be our critical accounting policies and estimates since they are very important to the understanding of our financial condition and results and require our most subjective and complex judgments. We have discussed the development, selection and disclosure of such policies and estimates with the Audit Committee of our Board of Directors. For a discussion of our significant accounting policies, refer to Part II, Item 8, “Note“Financial Statements and Supplementary Data, Note 1— Organization and Significant Accounting Policies.”
We prepare our consolidated financial statements in accordance with accounting principles generally accepted in the U.S.United States (“GAAP”), which require us to make estimates that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosures of contingent assets and liabilities. These estimates require significant judgments and assumptions. We base our estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying amounts of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates.
Principles of Consolidation
The consolidated financial statements include our accounts and those of our wholly-owned subsidiaries and entities in which we hold a controlling financial interest. OurUntil December 3, 2019, our consolidated financial statements includeincluded the accounts of two joint ventures, in each of which we ownowned a 50 percent interest. On December 3, 2019, we acquired the remaining 50 percent interest not owned by us and as a result the two joint ventures became our wholly-owned subsidiaries. Our historical ownership interest meetsin the joint ventures met the definition of variable interest under Financial Accounting Standards Board (“FASB”) codification and we have determined that we arewere the primary beneficiary. Intercompany balances and transactions have been eliminated in consolidation.
The combined carrying amount of the Bully-class drillships at December 31, 2017 and 2016 totaled $1.3 billion and $1.4 billion, respectively. These assets were primarily funded through partner equity contributions. Cash held by the Bully joint ventures totaled approximately $41.6 million at December 31, 2017 as compared to approximately $34.7 million at December 31, 2016.
Basis of Presentation-U.K.Presentation-UK Companies Act 2006 Section 435 Statement
The accompanying consolidated financial statements have been prepared in accordance with US GAAP, which the Board of Directors considerconsiders to be the most meaningful presentation of our results of operations and financial position. The accompanying consolidated financial statements do not constitute statutory accounts required by the UK Companies Act 2006 (“Companies Act”), which will be prepared in accordance


with International Financial Reporting Standards, as adopted by the European Union and delivered to the Registrar of Companies in the UK following the annual general meeting of shareholders.
Property and Equipment
Property and equipment is stated at cost, reduced by provisions to recognize economic impairment in value whenever events or changes in circumstances indicate an asset’s carrying value may not be recoverable. At December 31, 20172020 and 2016,2019, we had $83.5$99.8 million and $112$88.9 million of construction-in-progress, respectively. Such amounts are included in “Property and equipment, at cost” in the accompanying
47


Consolidated Balance Sheets. Major replacements and improvements are capitalized. When assets are sold, retired or otherwise disposed of, the cost and related accumulated depreciation are eliminated from the accounts and the gain or loss is recognized. Drilling equipment and facilities are depreciated using the straight-line method over their estimated useful lives as of the date placed in service or date of major refurbishment. Estimated useful lives of our drilling equipment range from three to thirty years. Other property and equipment is depreciated using the straight-line method over useful lives ranging from two to forty years.
Interest is capitalized on construction-in-progress using the weighted average cost of debt outstanding during the period of construction. During the year ended December 31, 2017, there was no capitalized interest due to the completion of our newbuild program. Capitalized interest was $22.4 million and$25.0 million for the years ended December 31, 20162020, 2019 and 2015,2018, there was zero, $9.6 million and $2.9 million capitalized interest, respectively.
Scheduled maintenance of equipment is performed based on the number of hours operated in accordance with our preventative maintenance program. Routine repair and maintenance costs are charged to expense as incurred; however, the costs of the overhauls and asset replacement projects that benefit future periods and which typically occur every three to five years are capitalized when incurred and depreciated over an equivalent period. These overhauls and asset replacement projects are included in “Property and equipment, at cost” in the Consolidated Balance Sheets. Such amounts, net of accumulated depreciation, totaled $149.3$129.6 million and $187.0$143.4 million at December 31, 20172020 and 2016,2019, respectively. Depreciation expense from continuing operations related to overhauls and asset replacement totaled $79.2$55.4 million, $86.0$61.3 million and $75.0$66.9 million for the years ended December 31, 2017, 20162020, 2019 and 2015,2018, respectively.
We evaluate the impairment of property and equipment whenever events or changes in circumstances (including the decision to cold stack, retire or sell a rig) indicate that the carrying amount of an asset may not be recoverable. An impairment loss on our property and equipment may exist when the estimated undiscounted cash flows expected to result from the use of the asset and its eventual disposition are less than its carrying amount. Any impairment loss recognized represents the excess of the asset's carrying value over the estimated fair value. As part of this analysis, we make assumptions and estimates regarding future market conditions. To the extent actual results do not meet our estimated assumptions, for a given rig or piece of equipment, we may take an impairment loss in the future.
During the years ended December 31, 2017, 20162020, 2019 and 20152018, we recognized a non-cash loss on impairment of $121.6$3.9 billion, $615.3 million $1.5 billion, and $418.3$802.1 million, respectively, related to our long-lived assets. See Part II, Item 7, “Management“Management’s Discussion and Analysis—Analysis of Financial Condition and Results of Operations— Executive Overview,” and Part II, Item 8, “Financial Statements and Supplementary Data, Note 6— Impairment,”Loss on Impairment” for additional information.

Revenue Recognition
The activities that primarily drive the revenue earned in our drilling contracts include (i) providing a drilling rig and the crew and supplies necessary to operate the rig, (ii) mobilizing and demobilizing the rig to and from the drill site, and (iii) performing rig preparation activities and/or modifications required for the contract. Consideration received for performing these activities may consist of dayrate drilling revenue, mobilization and demobilization revenue, contract preparation revenue and reimbursement revenue. We account for these integrated services provided within our drilling contracts as a single performance obligation satisfied over time and comprised of a series of distinct time increments in which we provide drilling services.
Our typical dayratestandard drilling contracts require our performance of a variety of services for a specified period of time. We determine progress towards completionthat we operate the rig at the direction of the customer throughout the contract by measuring efforts expendedterm (which is the period we estimate to benefit from the corresponding activities and generally ranges from two to 60 months). The activities performed and the costlevel of services requiredservice provided can vary hour to performhour. Our obligation under a drillingstandard contract asis to provide whatever level of service is required by the basis for our revenue recognition. Revenues generated from our dayrate-basis drilling contracts and labor contracts are recognized on a per day basis as services are performed and begin upon the contract commencement, as defined under the specified drilling contract. Dayrate revenues are typically earned, and contract drilling expenses are typically incurred ratably over the term of our drilling contracts. We review and monitor our performance under our drilling contracts to confirm the basis for our revenue recognition. Revenues from bonuses are recognized when earned, and when collectability is reasonably assured.
In our dayrate drilling contracts, we typically receive compensation and incur costs for mobilization, equipment modificationoperator, or other activities prior to the commencement of a contract. Any such compensation may be paid through a lump-sum payment or other daily compensation. Pre-contract compensation and costs are deferred until the contract commences. The deferred pre-contract compensation and costs are amortized, using the straight-line method, into income or losscustomer, over the term of the initialcontract. We are, therefore, under a stand-ready obligation throughout the entire contract duration. Consideration for our stand-ready obligation corresponds to distinct time increments, though the rate may be variable depending on various factors, and is recognized in the period regardlessin which the services are performed. The total transaction price is determined for each individual contract by estimating both fixed and variable consideration expected to be earned over the term of the activity taking place. This approachcontract. We have elected to exclude from the transaction price measurement all taxes assessed by a governmental authority. See further discussion regarding the allocation of the transaction price to the remaining performance obligations below.
The amount estimated for variable consideration may be subject to interrupted or restricted rates and is consistentonly included in the transaction price to the extent that it is probable that a significant reversal of previously recognized revenue will not occur throughout the term of the contract (“constrained revenue”). When determining if variable consideration should be constrained, management considers whether there are factors outside the Company’s control that could result in a significant reversal of revenue as well as the likelihood and magnitude of a potential reversal of revenue. These estimates are re-assessed each reporting period as required.
Dayrate Drilling Revenue. Our drilling contracts generally provide for payment on a dayrate basis, with higher rates for periods when the drilling unit is operating and lower rates or zero rates for periods when drilling operations are interrupted or restricted. The dayrate invoices billed to the customer are typically determined based on the varying rates applicable to the specific activities performed on an hourly basis. Such dayrate consideration is allocated to the distinct hourly increment it relates to within the contract term, and therefore, recognized in line with the economicscontractual rate billed for the services provided for any given hour.
48


Mobilization/Demobilization Revenue. We may receive fees (on either a fixed lump-sum or variable dayrate basis) for the mobilization and demobilization of our rigs. These activities are not considered to be distinct within the context of the contract and, therefore, the associated revenue is allocated to the overall performance obligation and the associated pre-operating costs are deferred. We record a contract liability for mobilization fees received and a deferred asset for costs. Both revenue and pre-operating costs are recognized ratably over the initial term of the related drilling contract.
In most contracts, there is uncertainty as to the amount of expected demobilization revenue due to contractual provisions that stipulate that certain conditions must be present at contract completion for such revenue to be received and as to the amount thereof, if any. For example, contractual provisions may require that a rig demobilize a certain distance before the demobilization revenue is payable or the amount may vary dependent upon whether or not the rig has additional contracted work within a certain distance from the wellsite. Therefore, the estimate for such revenue may be constrained, as described earlier, depending on the facts and circumstances pertaining to the specific contract. We assess the likelihood of receiving such revenue based on past experience and knowledge of the market conditions. In cases where demobilization revenue is expected to be received upon contract completion, it is estimated as part of the overall transaction price at contract inception and recognized in earnings ratably over the initial term of the contract with an offset to an accretive contract asset.
Contract Preparation Revenue. Some of our drilling contracts require downtime before the start of the contract to prepare the rig to meet customer requirements. At times, we may be compensated by the customer for such work (on either a fixed lump-sum or variable dayrate basis). These activities are not considered to be distinct within the context of the contract and, therefore, the related revenue is allocated to the overall performance obligation and recognized ratably over the initial term of the related drilling contract. We record a contract liability for contract preparation fees received, which is amortized ratably to contract drilling revenue over the initial term of the related drilling contract.
Bonuses, Penalties and Other Variable Consideration. We may receive bonus increases to revenue or penalty decreases to revenue. Based on historical data and ongoing communication with the operator/customer, we are able to reasonably estimate this variable consideration. We will record such estimated variable consideration and re-measure our estimates at each reporting date. For revenue estimated, but not received, we will record to “Prepaid expenses and other current assets” on our Consolidated Balance Sheets.
Capital Modification Revenue. From time to time, we may receive fees from our customers for capital improvements to our rigs to meet contractual requirements (on either a fixed lump-sum or variable dayrate basis). Such revenue is allocated to the overall performance obligation and recognized ratably over the initial term of the related drilling contract as these activities are integral to our drilling activities and are not considered to be a stand-alone service provided to the customer within the context of our contracts. We record a contract liability for such fees and recognize them ratably as contract drilling revenue over the initial term of the related drilling contract.
Revenues Related to Reimbursable Expenses. We generally receive reimbursements from our customers for the purchase of supplies, equipment, personnel services and other services provided at their request in accordance with a drilling contract or other agreement. Such reimbursable revenue is variable and subject to uncertainty, as the amounts received and timing thereof is highly dependent on factors outside of our influence. Accordingly, reimbursable revenue is constrained revenue and not included in the total transaction price until the uncertainty is 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 as “Reimbursables and other” in our Consolidated Statements of Operations. Such amounts are recognized ratably over the period within the contract term during which the parties have contracted. Once a contract commences, we may conduct various activities, including drillingcorresponding goods and well bore related activities, rig maintenance and equipment installation, movement between well locations or other activities.services are to be consumed.
Deferred revenues from drilling contracts totaled $114.3$59.9 million and $134.4$65.1 million at December 31, 20172020 and 2016,2019, respectively. Such amounts are included in either “Other current liabilities” or “Other liabilities” in the accompanying Consolidated Balance Sheets, based upon our expected time of recognition. Related expenses deferred under drilling contracts totaled $55.7$13.9 million at December 31, 20172020 as compared to $72.8$30.8 million at December 31, 20162019 and are included in either “Prepaid expenses and other current assets,” “Other assets,” or “Property and equipment, net” in the accompanying Consolidated Balance Sheets, based upon our expected time of recognition.


In April 2015, we agreed to contract dayrate reductions for five rigs working for Saudi Aramco. Given current market conditions and based on discussions with the customer, we do not expect the rates for the rigs currently working for Saudi Aramco to return to the original contract rates during the remaining contract terms. In accordance with accounting guidance, we are recognizing the rate reductions on a straight-line basis over the remaining life of these Saudi Aramco contracts. At December 31, 2017 and 2016, two of the five original rigs had revenues recorded in excess of billings as a result of this recognition which totaled $6.9 million and $17.9 million, respectively, and are included in either “Prepaid expenses and other current assets” or “Other assets” in the accompanying Consolidated Balance Sheets, based upon our expected time of recognition.
We record reimbursements from customers for “out-of-pocket” expenses as revenues and the related direct cost as operating expenses.
Income Taxes
We currently operate, and have in the past operated, in a number of countries throughout the world and our tax returns filed in those jurisdictions are subject to review and examination by tax authorities within those jurisdictions. We recognize uncertain tax positions that we believe have a greater than 50 percent likelihood of being sustained.sustained upon challenge by a tax authority. We cannot predict or provide assurance as to the ultimate outcome of any existing or future assessments. Our netgross deferred tax asset balance at year-end reflects the application of our income tax accounting policies and is based on management’s estimates, judgments and assumptions regarding realizability. If it is more likely than not that a portion of the deferred tax assets will not be realized in a future period, the deferred tax assets will be reduced by a valuation allowance based on management’s estimates. The companyCompany has adopted an accounting policy to look through the outside basis of partnerships and all other flow-through entities and exclude these from the computation of deferred taxes.
During 2014, the IRS began
49


The Internal Revenue Service (“IRS”) has completed its examination of our tax reporting in the U.S.procedures, including all appeals and administrative reviews, for the taxable years ended December 31, 2010 and 2011. The2012 through December 31,2017. In May 2020, the IRS examination team has completed its examination of our 2010 and 2011 U.S. tax returns and proposednotified us that it was no longer proposing any adjustments and deficiencies with respect to certain items that were reported by usour tax reporting for the 2010taxable years ended December 31, 2012 through December 31, 2017. Subsequent to our filing of an Application for Tentative Refund with the IRS under the CARES Act in the months of April and 2011August 2020, the IRS informed us that it would be conducting a limited scope examination of the taxable years ended December 31, 2012, 2013, 2014, 2018 and 2019. In the first quarter of 2020, we filed a foreign tax years. On December 19, 2016, we received the Revenue Agent Report (“RAR”) from the IRS.credit refund claim for taxable year 2009. The IRS is currently auditing taxable year 2009 in relation to our refund claim. We believe that we have accurately reported all amounts in our returns.
Audit claims of approximately $96.1 million attributable to income and other business taxes were assessed against Noble entities in Mexico related to tax returns,years 2007, 2009 and have submitted administrative protests with the IRS Office of Appeals contesting the examination team’s proposed adjustments.2010, in Australia related to tax years 2013 to 2016, in Guyana related to tax years 2019 and 2020 and in Saudi Arabia related to tax years 2015 to 2018. We intend to vigorously defend our reported positions, and believe the ultimate resolution of the adjustments proposed by the IRS examination teamaudit claims will not have a material adverse effect on our consolidated financial statements. During the third quarter of 2017, the IRS initiated its examination of our 2012, 2013, 2014 and 2015 tax returns.
In previous periods, we reported that Mexican and Brazilian authorities had made significant tax assessments against Paragon Offshore entities, a portion of which related to Noble’s business that operated through Paragon Offshore-retained entities in Mexico and Brazil prior to the Spin-off. As a result of the termination of the Separation Agreements, we no longer have any indemnity obligations in respect of these tax claims made against Paragon Offshore entities, and responsibility for these claims has reverted back to the applicable Paragon Offshore entity. Audit claims of approximately $48.3 million attributable to income and other business taxes have been assessed against Noble entities in Mexico.
In previous periods, we also reported that Petrobras had notified us that it was challenging assessments by Brazilian tax authorities of withholding taxes associated with the provision of drilling rigs for its operations in Brazil during 2008 and 2009. Petrobras had also notified us that if Petrobras was ultimately forced to pay such withholding taxes, it would seek reimbursement from Paragon Offshore who would then seek reimbursement from us for the portion of the withholding that was allocable to our drilling rigs. As a result of the termination of the Separation Agreements, we no longer have any indemnity obligation in respect of these withholding claims made against a Paragon Offshore entity, and responsibility for these claims has reverted back to the applicable Paragon Offshore entity.
On December 22, 2017, the President of the United States signed the into law legislation informally known as the Tax Cuts and Job Act (the “Act”). The Act represents major tax reform legislation that, among other provisions, reduces the U.S. corporate tax rate. The Company recognized the income tax effects of the Act in its 2017 financial statements, including $109.0 million of tax benefit recorded principally due to the write-down of our net deferred tax liabilities, in accordance with Accounting Standards Codification ("ASC") Topic 740, Income Taxes, in the reporting period in which the Act was enacted. Based on guidance issued from Staff Accounting Bulletin No. 118 ("SAB 118"), the Company has not provided provisional estimates for items in which the accounting for certain income tax effects of the Act is incomplete and as such, the Company will continue to apply ASC 740 on the basis of the laws in effect immediately before the enactment of the Act. For more information on the Act and its effect on our consolidated financial statements, see Part II, Item 8, “Note 10— Income Taxes.”
The Act introduces a new anti-deferral provision, which subjects a U.S. parent shareholder to current tax on certain income referred to as Global Intangible Low-Taxed Income (“GILTI”), of its foreign subsidiaries. The company has not made any adjustments related to potential GILTI tax in its financial statements and has adopted a policy to treat tax due on future U.S. inclusions in taxable income as period costs when incurred.
Insurance Reserves
We maintain various levels of self-insured retention for certain losses including property damage, loss of hire, employment practices liability, employers’ liability and general liability, among others. We accrue for property damage and loss of hire charges on a per event basis.
Employment practices liability claims are accrued based on actual claims during the year. Maritime employer’s liability claims are generally estimated using actuarial determinations. General liability claims are estimated by our internal claims department by evaluating the facts and


circumstances of each claim (including incurred but not reported claims) and making estimates based upon historical experience with similar claims. At December 31, 20172020 and 2016,2019, loss reserves for personal injury and protection claims totaled $22.0$30.9 million and $22.1$27.9 million, respectively, and such amounts are included in “Other current liabilities” and “Liabilities subject compromise” in the accompanying Consolidated Balance Sheets.
Certain Significant Estimates and Contingent Liabilities
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period. Certain accounting policies involve judgments and uncertainties to such an extent that there is reasonable likelihood that materially different amounts could have been reported under different conditions, or if different assumptions had been used. We evaluate our estimates and assumptions on a regular basis. We base our estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates and assumptions used in preparation of our consolidated financial statements. We follow FASB standards regarding contingent liabilities, which are discussed in Part II, Item 8, "Financial“Financial Statements and Supplementary Data, “Note 14—Note 16— Commitments and Contingencies.”
Off-Balance Sheet Arrangements
We have no off-balance sheet arrangements as that term is defined in Item 303(a)(4)(ii) of Regulation S-K.
New Accounting Pronouncements
See Part II, Item 8, “Financial Statements and Supplementary Data, Note 1— Organization and Significant Accounting Policies,” to the Consolidated Financial StatementsPolicies” for a description of the recent accounting pronouncements.
Item 7A. Quantitative and Qualitative Disclosures about Market Risk.
Market risk is the potential for loss due to a change in the value of a financial instrument as a result of fluctuations in interest rates, currency exchange rates or equity prices, as further described below.
Interest Rate Risk
We are subject to market risk exposure related to changes in interest rates on borrowings under the Credit Facilities. Interest on borrowings under our Credit Facilities is at an agreed upon percentage point spread over LIBOR, or a base rate stated in the agreements. At December 31, 2017, we had no borrowings outstanding under our Credit Facilities.
During 2017 and 2016, we experienced debt rating downgrades by Moody’s Investors Service and S&P Global Ratings, which reduced our debt ratings significantly below investment grade. As a result of these downgrades, we experienced interest rate increases during 2017 and 2016 on the 2018 Notes, 2025 Notes and 2045 Notes, all of which are subject to provisions that vary the applicable interest rates based on our debt rating. On October 18, 2017 S&P Global Ratings further reduced our debt rating, which will increase the interest rates on the 2025 Notes and 2045 Notes to 7.95% and 8.95%, respectively, beginning in April 2018. Once the new interest rates take effect in April 2018, these senior notes will have reached the contractually-defined maximum interest rate set for each rating agency and no further interest rate increase will occur.
Our other outstanding senior notes, including the 2024 Notes issued in December 2016, and 2026 Notes issued in January 2018, do not contain provisions varying applicable interest rates based upon our credit ratings.
We maintain certain debt instruments at a fixed rate whose fair value will fluctuate based on changes in market expectations for interest rates and perceptions of our credit risk. The fair value of our total debt was $3.4 billion and $3.8 billion at December 31, 2017 and December 31, 2016, respectively. The decrease in the fair value of debt relates to the maturity of our 2017 Notes and changes in market expectations for interest rates and perceptions of our credit risk.
Foreign Currency Risk
Although we are a UKCayman Islands company, we define foreign currency as any non-U.S.non-US denominated currency. Our functional currency is primarily the U.S. Dollar, which is consistent with the oil and gas industry.US Dollar. However, outside the United States, a portion of our expenses are incurred in local currencies. Therefore, when the U.S.US Dollar weakens (strengthens) in relation to the currencies of the countries in which we operate, our expenses reported in U.S.US Dollars will increase (decrease).
We are exposed to risks on future cash flows to the extent that local currency expenses exceed revenues denominated in local currency that are other than the functional currency. To help manage this potential risk, we periodically enter into derivative instruments to manage our
50


exposure to fluctuations in currency exchange rates, and we may conduct hedging activities in future periods to mitigate such exposure. These contracts are


primarily accounted for as cash flow hedges, with the effective portion of changes in the fair value of the hedge recorded on the Consolidated Balance SheetSheets and in “Accumulated other comprehensive income (loss)” (“AOCI”). Amounts recorded in AOCI are reclassified into earnings in the same period or periods that the hedged item is recognized in earnings. The ineffective portion of changes in the fair value of the hedged item is recorded directly to earnings. We have documented policies and procedures to monitor and control the use of derivative instruments. We do not engage in derivative transactions for speculative or trading purposes, nor are we a party to leveraged derivatives.
Several of our regional shorebases including our North Sea operations, have a significant amount of their cash operating expenses payable in local currencies. To limit the potential risk of currency fluctuations, we periodically enter into forward contracts, which settlehave historically settled monthly in the operations’ respective local currencies. All of these contracts havehad a maturity of less than 12 months. During 2017 and 2016,2020, we did not enter into any forward contracts. During 2019, we entered into forward contracts of approximately $37.6$15.8 million, and $53.1 million, respectively, all of which settled during their respective years.2019. At both December 31, 20172020 and 2016,2019, we had no outstanding derivative contracts. Based on current projections, a 10% increase in the average exchange rates of all foreign currencies would hypothetically increase our future estimated operating expenses by approximately $11.0 million.
Market Risk
We have a U.S.US noncontributory defined benefit pension plan that covers certain salaried employees and a U.S.US noncontributory defined benefit pension plan that covers certain hourly employees, whose initial date of employment is prior to August 1, 2004 (collectively referred to as our “qualified U.S.US plans”). These plans are governed by the Noble Drilling Employees’ Retirement Trust. The benefits from these plans are based primarily on years of service and, for the salaried plan, employees’ compensation near retirement. These plans are designed to qualify under the Employee Retirement Income Security Act of 1974 (“ERISA”), and our funding policy is consistent with funding requirements of ERISA and other applicable laws and regulations. We make cash contributions, or utilize credits available to us, for the qualified U.S.US plans when required. The benefit amount that can be covered by the qualified U.S.US plans is limited under ERISA and the Internal Revenue Code (“IRC”) of 1986. Therefore, we maintain an unfunded, nonqualified excess benefit plan designed to maintain benefits for specified employees at the formula level in the qualified salary U.S.US plan. We refer to the qualified U.S.US plans and the excess benefit plan collectively as the “U.S.“US plans.”
In addition to the U.S.US plans, each of Noble Drilling (Land Support) Limited, and Noble Resources Limited, bothan indirect, wholly-owned subsidiariessubsidiary of Noble-UK,Noble, maintains a pension plan that covers all of its salaried, non-union employees, whose most recent date of employment is prior to April 1, 2014 (collectively referred(referred to as our “non-U.S. plans”“non-US plan”). Benefits are based on credited service and employees’ compensation, as defined by the plans.non-US plan.
Changes inThe Company’s pension plan assets are exposed to the market asset values relatedprices of debt and equity securities. Changes to the pension plans noted above couldplan asset values can impact the Company’s pension expense, funded status and future minimum funding requirements. The Company aims to reduce risk through asset diversification and by investing in long duration fixed-income securities that have a material impact upon our Consolidated Statementduration similar to that of Comprehensive Income (Loss)its pension liabilities. At December 31, 2020, the value of the investments in the pension funds was $306.2 million, and a hypothetical 10.0% percent decrease in the value of the investments in the fund would have reduced the value of the fund by approximately $30.6 million. A significant decline in the value of pension assets could result in material cash expendituresrequire Noble to increase funding of its pension plans in future periods, which could adversely affect cash flows in those periods.

In addition, a decline in the fair value of these plan assets, in the absence of additional cash contributions to the plans by Noble, could increase the amount of pension cost required to be recorded in future periods by Noble.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Report of Independent Registered Public Accounting Firm

Tothe Board of Directors and
Shareholders of Noble Corporation plcCorporation:


Opinions on the Financial Statements and Internal Control Overover Financial Reporting

We have audited the accompanying consolidated balance sheets of Noble Corporation plc(formerly known as Noble Holding Corporation plc) and its subsidiaries (the “Company”) as of December 31, 20172020 and 2016,2019, and the related consolidated statements of operations, of comprehensive income (loss), of equity and of cash flows and equity for each of the three years in the period ended December 31, 2017,2020, including the related notes (collectively referred to as the “consolidated financial statements”). We also have audited the Company's internal control over financial reporting as of December 31, 2017,2020, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 20172020 and 2016,2019, and the results of theirits operations and theirits cash flows for each of the three years in the period ended December 31, 20172020 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017,2020, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.


Basis for Opinions

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management'sManagement’s Annual Report on Internal Control Over Financial Reporting as appearing under Item 9A. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB")(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 audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements 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. 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 audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.


Definition and Limitations of Internal Control Overover 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 (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) 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 (iii) 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.



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.

Critical Audit Matters
The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) 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 matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.
Impairment Assessment – Certain Rigs Within Drilling Equipment and Facilities Assets
As described in Notes 1, 5 and 6 to the consolidated financial statements, the balance of drilling equipment and facilities was $4.5 billion as of December 31, 2020, which included a $2.8 billion impairment related to certain rigs for the year ended December 31, 2020. Management evaluates property and equipment for impairment whenever there are changes in facts that suggest that the carrying value of the asset is not recoverable. As part of this analysis, management makes assumptions and estimates regarding future market conditions. When circumstances indicate that the carrying value of the assets may not be recoverable, management compares the carrying value to the expected undiscounted pre-tax future cash flows (estimated using an undiscounted cash flow model) for the associated rig for which identifiable cash flows are independent of cash flows of other assets. If the expected undiscounted pre-tax future cash flows are lower than the carrying value, the capitalized costs are reduced to fair value. An impairment loss is recognized to the extent that an asset's carrying value exceeds its estimated fair value. Management estimated the fair values of these units using a weighting between an income valuation approach and a market approach, utilizing significant unobservable inputs, representative of a Level 3 fair value measurement. Assumptions used in the assessment included, but were not limited to, future marketability of each unit in light of the current market conditions and its current technical specifications, timing of future contract awards and expected operating dayrates, operating costs, utilization rates, discount rates, capital expenditures, market values, weighting of market values, reactivation costs, estimated economic useful lives and, in certain cases, the belief that a drilling unit is no longer marketable and is unlikely to return to service in the near to medium term.
The principal considerations for our determination that performing procedures relating to the impairment assessment of certain rigs within drilling equipment and facilities assets is a critical audit matter are (i) the significant judgment by management when developing the undiscounted pre-tax future cash flows and estimated fair values of the drilling equipment and facilities assets; (ii) a high degree of auditor judgment, subjectivity, and effort in performing procedures and evaluating management’s significant assumptions related to the expected operating dayrates, operating costs, utilization rates, and the discount rate; and (iii) the audit effort involved the use of professionals with specialized skill and knowledge.
Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the drilling equipment and facilities assets impairment assessment. These procedures also included, among others (i) testing management’s process for developing the undiscounted pre-tax future cash flows and fair value estimates; (ii) evaluating the appropriateness of the undiscounted pre-tax cash flow and discounted cash flow model; (iii) testing the completeness and accuracy of underlying data used in the model; and (iv) evaluating the significant assumptions used by management related to the expected operating dayrates, operating costs, utilization rates, and the discount rate. Evaluating management’s assumptions related to the expected operating day rates, operating costs and utilization rates involved evaluating whether the assumptions used by management were reasonable considering (i) the current and past performance of the assets; (ii) the consistency with external market and industry data; and (iii) whether these assumptions were consistent with evidence obtained in other areas of the audit. Professionals with specialized skill and knowledge were used to assist in the evaluation of the discounted cash flow model and the discount rate.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRMReport of Independent Registered Public Accounting Firm


Tothe Board of Directors and
Shareholder of Noble CorporationFinance Company:


Opinions on the Financial Statements and Internal Control Overover Financial Reporting

We have audited the accompanying consolidated balance sheets of Noble CorporationFinance Company (formerly known as Noble Corporation) and its subsidiaries (the “Company”) as of December 31, 20172020 and 2016,2019, and the related consolidated statements of operations, of comprehensive income (loss), of equity and of cash flows and equity for each of the three years in the period ended December 31, 2017,2020, including the related notes (collectively referred to as the “consolidated financial statements”). We also have audited the Company's internal control over financial reporting as of December 31, 2017,2020, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 20172020 and 2016,2019, and the results of theirits operations and theirits cash flows for each of the three years in the period ended December 31, 20172020 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017,2020, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.


Basis for Opinions

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management'sManagement’s Annual Report on Internal Control Over Financial Reporting as appearing under Item 9A. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB")(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 audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements 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. 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 audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.


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 (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) 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 (iii) 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.

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.

Critical Audit Matters
The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) 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 matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.
Impairment Assessment – Certain Rigs Within Drilling Equipment and Facilities Assets
As described in Notes 1, 5 and 6 to the consolidated financial statements, the balance of drilling equipment and facilities was $4.5 billion as of December 31, 2020, which included a $2.8 billion impairment related to certain rigs for the year ended December 31, 2020. Management evaluates property and equipment for impairment whenever there are changes in facts that suggest that the carrying value of the asset is not recoverable. As part of this analysis, management makes assumptions and estimates regarding future market conditions. When circumstances indicate that the carrying value of the assets may not be recoverable, management compares the carrying value to the expected undiscounted pre-tax future cash flows (estimated using an undiscounted cash flow model) for the associated rig for which identifiable cash flows are independent of cash flows of other assets. If the expected undiscounted pre-tax future cash flows are lower than the carrying value, the capitalized costs are reduced to fair value. An impairment loss is recognized to the extent that an asset's carrying value exceeds its estimated fair value. Management estimated the fair values of these units using a weighting between an income valuation approach and a market approach, utilizing significant unobservable inputs, representative of a Level 3 fair value measurement. Assumptions used in the assessment included, but were not limited to, future marketability of each unit in light of the current market conditions and its current technical specifications, timing of future contract awards and expected operating dayrates, operating costs, utilization rates, discount rates , capital expenditures, market values, weighting of market values, reactivation costs, estimated economic useful lives and, in certain cases, the belief that a drilling unit is no longer marketable and is unlikely to return to service in the near to medium term.
The principal considerations for our determination that performing procedures relating to the impairment assessment of certain rigs within drilling equipment and facilities assets is a critical audit matter are (i) the significant judgment by management when developing the undiscounted pre-tax future cash flows and estimated fair values of the drilling equipment and facilities assets; (ii) a high degree of auditor judgment, subjectivity, and effort in performing procedures and evaluating management’s significant assumptions related to the expected operating dayrates, operating costs, utilization rates, and the discount rate; and (iii) the audit effort involved the use of professionals with specialized skill and knowledge.
Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the drilling equipment and facilities assets impairment assessment. These procedures also included, among others (i) testing management’s process for developing the undiscounted pre-tax future cash flow and fair value estimates; (ii) evaluating the appropriateness of the undiscounted pre-tax cash flow and discounted cash flow model; (iii) testing the completeness and accuracy of underlying data used in the model; and (iv) evaluating the significant assumptions used by management related to the expected operating dayrates, operating costs, utilization rates, and the discount rate. Evaluating management’s assumptions related to the expected operating day rates, operating costs and utilization rates involved evaluating whether the assumptions used by management were reasonable considering (i) the current and past performance of the assets; (ii) the consistency with external market and industry data; and (iii) whether these assumptions were consistent with evidence obtained in other areas of the audit. Professionals with specialized skill and knowledge were used to assist in the evaluation of the discounted cash flow model and the discount rate.

Note 1— Organization and Significant Accounting Policies
Noble Corporation, plc, a public limitedan exempted company incorporated underin the laws of England and WalesCayman Islands with limited liability (“Noble-UK”Noble” or “Successor”), is a leading offshore drilling contractor for the oil and gas industry. We provide contract drilling services to the international oil and gas industry with our global fleet of mobile offshore drilling units. Noble and its predecessors have been engaged in the contract drilling of oil and gas wells since 1921. As of December 31, 2017,2020, our fleet of 19 drilling rigs consisted of eight drillships, six semisubmersibles7 floaters and 1412 jackups.
We report our contract drilling operations as a single reportable segment, Contract Drilling Services, which reflects how we manage our business. The mobile offshore drilling units comprising our offshore rig fleet operate in a global market for contract drilling services and are often redeployed to different regions due to changing demands of our customers, which consist primarily of large, integrated, independent and government-owned or controlled oil and gas companies throughout the world.
On July 31, 2020 (the “Petition Date”), our former parent company, Noble Holding Corporation plc (formerly known as Noble Corporation plc), a public limited company incorporated under the laws of England and Wales (“Legacy Noble” or the “Predecessor”), and certain of its subsidiaries, including Noble Finance Company (formerly known as Noble Corporation), a Cayman Islands company (“Noble-Cayman”Finco”), isfiled voluntary petitions in the United States Bankruptcy Court for the Southern District of Texas (the “Bankruptcy Court”) seeking relief under chapter 11 of title 11 of the United States Code (the “Bankruptcy Code”). On September 4, 2020, the Debtors (as defined herein) filed with the Bankruptcy Court the Joint Plan of Reorganization of Noble Corporation plc and its Debtor Affiliates, which was subsequently amended on October 8, 2020 and October 13, 2020 and modified on November 18, 2020 (as amended, modified or supplemented, the “Plan”), and the related disclosure statement (the “Disclosure Statement”). On September 24, 2020, 6 additional subsidiaries of Legacy Noble (together with Legacy Noble and its subsidiaries that filed on the Petition Date, as the context requires, the “Debtors”) filed voluntary petitions in the Bankruptcy Court. The chapter 11 proceedings were jointly administered under the caption Noble Corporation plc, et al. (Case No. 20-33826) (the “Chapter 11 Cases”). On November 20, 2020, the Bankruptcy Court entered an order confirming the Plan. In connection with the Chapter 11 Cases and the Plan, on and prior to the Effective Date (as defined herein), Legacy Noble and certain of its subsidiaries effectuated certain restructuring transactions pursuant to which Legacy Noble formed Noble as an indirect wholly-owned subsidiary of Noble-UK,Legacy Noble and transferred to Noble substantially all of the subsidiaries and other assets of Legacy Noble. On February 5, 2021 (the “Effective Date”), the Plan became effective in accordance with its terms and the Debtors emerged from the Chapter 11 Cases.
Noble is the successor issuer to Legacy Noble for purposes of and pursuant to Rule 15d-5 of the Exchange Act. References to the “Company,” “we,” “us” or “our” in this Annual Report are to Noble, together with its consolidated subsidiaries, when referring to periods following the Effective Date, and to Legacy Noble, together with its consolidated subsidiaries, when referring to periods prior to the Effective Date.
Finco was an indirect, wholly-owned subsidiary of Legacy Noble prior to the Effective Date and has been a direct, wholly-owned subsidiary of Noble, our publicly-traded parent company. Noble-UK’scompany, since the Effective Date. Noble’s principal asset is all of the shares of Noble-Cayman. Noble-CaymanFinco. Finco has no public equity outstanding. The consolidated financial statements of Noble-UKNoble include the accounts of Noble-Cayman,Finco, and Noble-UKNoble conducts substantially all of its business through Noble-CaymanFinco and its subsidiaries.
Going Concern
A prolonged offshore industry downturn which began in 2014 was further exacerbated throughout 2020 by a steep decline in crude oil demand and crude oil price instability. The severity and length of these industry challenges negatively impacted our liquidity position resulting in higher than previously anticipated free cash flow deficits, increased borrowings and reduced availability under our 2017 Credit Facility (as defined herein), and significantly reduced access to sources of new capital. We actively pursued a variety of transactions and cost-cutting measures during the first half of 2020, including, but not limited to, potential refinancing transactions by us or our subsidiaries, potential capital exchange transactions, and a potential waiver from lenders under, or amendment to, our 2017 Credit Facility.
Legacy Noble performed the required assessments in conjunction with the filing of its Form 10-Q for the three months ended March 31, 2020 and determined, at that time, that substantial doubt about its ability to continue as a going concern existed. Subsequent to emergence from the Chapter 11 Cases, Noble performed a reassessment and concluded there was no longer substantial doubt regarding the Noble’s ability to continue as a going concern one year from the date of filing the Noble's Form 10-K for the year ended December 31, 2020. This was primarily due to the cancellation of Legacy Noble’s outstanding debt obligations and increased liquidity with the Exit Credit Agreement (as defined herein). Management’s assessment was based on the relevant conditions that were known and reasonably knowable at the issuance date and included the Noble’s post-emergence financial condition and liquidity sources, forecasted future cash flows, contractual obligations and

commitments and other conditions that could adversely affect the Noble’s ability to meet its obligations through one year from the issuance date of the Form 10-K.
Principles of Consolidation
The consolidated financial statements include our accounts and those of our wholly-owned subsidiaries and entities in which we hold a controlling financial interest. OurUntil December 3, 2019 our consolidated financial statements also includeincluded the accounts of two2 joint ventures, in each of which we ownowned a 50 percent interest. On December 3, 2019, we acquired the remaining 50 percent interest not owned by us and as a result the 2 joint ventures became our wholly-owned subsidiaries. Our historical ownership interest meetsin the joint ventures met the definition of variable interest under Financial Accounting Standards Board (“FASB”) codification and we have determined that we arewere the primary beneficiary. Intercompany balances and transactions have been eliminated in consolidation.
Cash and Cash Equivalents
Cash and cash equivalents include cash on hand, demand deposits with banks and all highly liquid investments with original maturities of three months or less. Our cash, cash equivalents and short-term investments are subject to potential credit risk, and certain of our cash accounts carry balances greater than the federally insured limits. Cash and cash equivalents are primarily held by major banks or investment firms. Our cash management and investment policies restrict investments to lower risk, highly liquid securities and we perform periodic evaluations of the relative credit standing of the financial institutions with which we conduct business.
Restricted Cash
We classify restricted cash balances in current assets if the restriction is expected to expire or otherwise be resolved within one year and in other assets if the restriction is expected to expire or otherwise be resolved in more than one year. As of December 31, 2020 and 2019, our Noble restricted cash balance consisted of $21.7 million and $1.3 million, respectively. As of December 31, 2020 and 2019, our Finco restricted cash balance consisted of$1.7 million and $1.3 million, respectively. All restricted cash is recorded in “Prepaid expenses and other current assets.” As of December 31, 2019, our restricted cash balance was associated with our financing of the Noble Johnny Whitstine and Noble Joe Knight. As of December 31, 2020, our restricted cash balance is to comply with restrictions from a Bankruptcy Court order to settle certain professional fees incurred upon or prior to our emergence from bankruptcy.
Accounts Receivable
We record accounts receivable at the amount we invoice our clients, net of allowance for credit losses. We provide an allowance for uncollectible accounts, as necessary. Our allowance for doubtful accounts as of December 31, 2020 and 2019 was $1.1 million and $1.9 million, respectively.
Property and Equipment
Property and equipment is stated at cost, reduced by provisions to recognize economic impairment. Major replacements and improvements are capitalized. When assets are sold, retired or otherwise disposed of, the cost and related accumulated depreciation are eliminated from the accounts and the gain or loss is recognized. Drilling equipment and facilities are depreciated using the straight-line method over their estimated useful lives as of the date placed in service or date of major refurbishment. Estimated useful lives of our drilling equipment range from three to thirty years. Other property and equipment is depreciated using the straight-line method over useful lives ranging from two to forty years. Included in accounts payable were $35.3 million and $36.0 million of capital accruals as of December 31, 2020 and 2019, respectively.
Interest is capitalized on long-term construction project using the weighted average cost of debt outstanding during the period of construction.
Scheduled maintenance of equipment is performed based on the number of hours operated in accordance with our preventative maintenance program. Routine repair and maintenance costs are charged to expense as incurred; however, the costs of the overhauls and asset replacement projects that benefit future periods and which typically occur every three to five years are capitalized when incurred and depreciated over an equivalent period. These overhauls and asset replacement projects are included in “Drilling equipment and facilities” in “Note 5— Property and Equipment.”
We evaluate our property and equipment for impairment whenever there are changes in facts that suggest that the value of the asset is not recoverable. As part of this analysis, we make assumptions and estimates regarding future market conditions. When circumstances indicate that the carrying value of the assets may not be recoverable, management compares the carrying value to the expected undiscounted pre-tax

(Unless otherwise indicated, dollar and share amounts in tables are in thousands)
future cash flows for the associated rig for which identifiable cash flows are independent of cash flows of other assets. If the expected undiscounted pre-tax future cash flows are lower than the carrying value, the net capitalized costs are reduced to fair value. An impairment loss is recognized to the extent that an asset's carrying value exceeds its estimated fair value. Fair value is generally estimated using a discounted cash flow model. The combined carryingexpected future cash flows used for impairment assessment and related fair value measurements are typically based on judgmental assessments of, but were not limited to, timing of future contract awards and expected operating dayrates, operating costs, utilization rates, discount rates, capital expenditures, reactivation costs, estimated economic useful lives and, in certain cases, our belief that a drilling unit is no longer marketable and is unlikely to return to service in the near to medium term, and considering all available information at the date of assessment. For more detailed information, see “Note 6— Loss on Impairment.”
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 three-level hierarchy, from highest to lowest level of observable inputs, are as follows:
Level 1 - Valuations based on quoted prices in active markets for identical assets;
Level 2 - Valuations based on observable inputs that do not meet the criteria for Level 1, including quoted prices in inactive markets and quoted prices in active markets for similar but not identical instruments; and
Level 3 - Valuations based on unobservable inputs.
Revenue Recognition
The activities that primarily drive the revenue earned in our drilling contracts include (i) providing a drilling rig and the crew and supplies necessary to operate the rig, (ii) mobilizing and demobilizing the rig to and from the drill site, and (iii) performing rig preparation activities and/or modifications required for the contract. Consideration received for performing these activities may consist of dayrate drilling revenue, mobilization and demobilization revenue, contract preparation revenue and reimbursement revenue. We account for these integrated services provided within our drilling contracts as a single performance obligation satisfied over time and comprised of a series of distinct time increments in which we provide drilling services.
Our standard drilling contracts require that we operate the rig at the direction of the customer throughout the contract term (which is the period we estimate to benefit from the corresponding activities and generally ranges from two to 60 months). The activities performed and the level of service provided can vary hour to hour. Our obligation under a standard contract is to provide whatever level of service is required by the operator, or customer, over the term of the contract. We are, therefore, under a stand-ready obligation throughout the entire contract duration. Consideration for our stand-ready obligation corresponds to distinct time increments, though the rate may be variable depending on various factors, and is recognized in the period in which the services are performed. The total transaction price is determined for each individual contract by estimating both fixed and variable consideration expected to be earned over the term of the contract. We have elected to exclude from the transaction price measurement all taxes assessed by a governmental authority. See further discussion regarding the allocation of the transaction price to the remaining performance obligations below.
The amount estimated for variable consideration may be subject to interrupted or restricted rates and is only included in the transaction price to the extent that it is probable that a significant reversal of previously recognized revenue will not occur throughout the term of the contract (“constrained revenue”). When determining if variable consideration should be constrained, management considers whether there are factors outside the Company’s control that could result in a significant reversal of revenue as well as the likelihood and magnitude of a potential reversal of revenue. These estimates are re-assessed each reporting period as required.
Dayrate Drilling Revenue. Our drilling contracts generally provide for payment on a dayrate basis, with higher rates for periods when the drilling unit is operating and lower rates or zero rates for periods when drilling operations are interrupted or restricted. The dayrate invoices billed to the customer are typically determined based on the varying rates applicable to the specific activities performed on an hourly basis. Such dayrate consideration is allocated to the distinct hourly increment it relates to within the contract term, and therefore, recognized in line with the contractual rate billed for the services provided for any given hour.
Mobilization/Demobilization Revenue. We may receive fees (on either a fixed lump-sum or variable dayrate basis) for the mobilization and demobilization of our rigs. These activities are not considered to be distinct within the context of the contract and, therefore, the associated revenue is allocated to the overall performance obligation and the associated pre-operating costs are deferred. We record a contract liability for mobilization fees received and a deferred asset for costs. Both revenue and pre-operating costs are recognized ratably over the initial term of the related drilling contract.

(Unless otherwise indicated, dollar and share amounts in tables are in thousands)
In most contracts, there is uncertainty as to the amount of expected demobilization revenue due to contractual provisions that stipulate that certain conditions must be present at contract completion for such revenue to be received and as to the Bully-class drillshipsamount thereof, if any. For example, contractual provisions may require that a rig demobilize a certain distance before the demobilization revenue is payable or the amount may vary dependent upon whether or not the rig has additional contracted work within a certain distance from the wellsite. Therefore, the estimate for such revenue may be constrained, as described earlier, depending on the facts and circumstances pertaining to the specific contract. We assess the likelihood of receiving such revenue based on past experience and knowledge of the market conditions. In cases where demobilization revenue is expected to be received upon contract completion, it is estimated as part of the overall transaction price at December 31, 2017contract inception and 2016 totaled $1.3 billion and $1.4 billion, respectively. These assets were primarily funded through partner equity contributions. Cash heldrecognized in earnings ratably over the initial term of the contract with an offset to an accretive contract asset.
Contract Preparation Revenue. Some of our drilling contracts require downtime before the start of the contract to prepare the rig to meet customer requirements. At times, we may be compensated by the Bully joint venturescustomer for such work (on either a fixed lump-sum or variable dayrate basis). These activities are not considered to be distinct within the context of the contract and, therefore, the related revenue is allocated to the overall performance obligation and recognized ratably over the initial term of the related drilling contract. We record a contract liability for contract preparation fees received, which is amortized ratably to contract drilling revenue over the initial term of the related drilling contract.
Bonuses, Penalties and Other Variable Consideration. We may receive bonus increases to revenue or penalty decreases to revenue. Based on historical data and ongoing communication with the operator/customer, we are able to reasonably estimate this variable consideration. We will record such estimated variable consideration and re-measure our estimates at each reporting date. For revenue estimated, but not received, we will record to “Prepaid expenses and other current assets” on our Consolidated Balance Sheets.
Capital Modification Revenue. From time to time, we may receive fees from our customers for capital improvements to our rigs to meet contractual requirements (on either a fixed lump-sum or variable dayrate basis). Such revenue is allocated to the overall performance obligation and recognized ratably over the initial term of the related drilling contract as these activities are integral to our drilling activities and are not considered to be a stand-alone service provided to the customer within the context of our contracts. We record a contract liability for such fees and recognize them ratably as contract drilling revenue over the initial term of the related drilling contract.
Revenues Related to Reimbursable Expenses. We generally receive reimbursements from our customers for the purchase of supplies, equipment, personnel services and other services provided at their request in accordance with a drilling contract or other agreement. Such reimbursable revenue is variable and subject to uncertainty, as the amounts received and timing thereof is highly dependent on factors outside of our influence. Accordingly, reimbursable revenue is constrained revenue and not included in the total transaction price until the uncertainty is 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 as “Reimbursables and other” in our Consolidated Statements of Operations. Such amounts are recognized ratably over the period within the contract term during which the corresponding goods and services are to be consumed.
Deferred revenues from drilling contracts totaled approximately $41.6$59.9 million and $65.1 million at December 31, 2017 as compared to approximately $34.72020 and 2019, respectively. Such amounts are included in either “Other current liabilities” or “Other liabilities” in the accompanying Consolidated Balance Sheets, based upon our expected time of recognition. Related expenses deferred under drilling contracts totaled $13.9 million at December 31, 2016.

We have maderecord reimbursements from customers for “out-of-pocket” expenses as revenues and the related direct cost as operating expenses.
Income Taxes
Income taxes are based on the laws and rates in effect in the countries in which operations are conducted or in which we or our subsidiaries are considered resident for income tax purposes. In certain reclassificationscircumstances, we expect that, due to changing demands of the offshore drilling markets and the ability to redeploy our prior periodoffshore drilling units, certain of such units will not reside in a location long enough to give rise to future tax consequences. As a result, no deferred tax asset or liability has been recognized in these circumstances. Should our expectations change regarding the length of time an offshore drilling unit will be used in a given location, we will adjust deferred taxes accordingly.
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 applicable jurisdictional tax rates at year-end. A valuation allowance for deferred tax assets is recorded when it is more likely than not that the deferred tax asset will not be realized in a future period.
We operate through various subsidiaries in numerous countries throughout the world, including the United States. Consequently, we are subject to changes in tax laws, treaties or regulations or the interpretation or enforcement thereof in the United States, UK and any other jurisdictions in which we or any of our subsidiaries operate or are resident. Our income tax expense is based upon our interpretation of the tax

Insurance Reserves
We have mademaintain various levels of self-insured retention for certain reclassificationslosses including property damage, loss of hire, employment practices liability, employers’ liability and general liability, among others. We accrue for property damage and loss of hire charges on a per event basis.
Employment practices liability claims are accrued based on actual claims during the year. Maritime employer’s liability claims are generally estimated using actuarial determinations. General liability claims are estimated by our internal claims department by evaluating the facts and circumstances of each claim (including incurred but not reported claims) and making estimates based upon historical experience with similar claims. At December 31, 2020 and 2019, loss reserves for personal injury and protection claims totaled $30.9 million and $27.9 million, respectively, and such amounts are included in “Other current liabilities” or “Liabilities subject to compromise” in the accompanying Consolidated Balance Sheets.
Earnings per Share
Our unvested share-based payment awards, which contain non-forfeitable rights to dividends, are participating securities and are included in the computation of earnings per share pursuant to the two-class method. The two-class method allocates undistributed earnings between common shares and participating securities. The diluted earnings per share calculation under the two-class method also includes the dilutive effect of potential shares issued in connection with stock options. The dilutive effect of stock options is determined using the treasury stock method.
Share-Based Compensation Plans
We record the grant date fair value of share-based compensation arrangements as compensation cost using a straight-line method over the service period. Share-based compensation is expensed or capitalized based on the nature of the employee’s activities.
Liability-Classified Awards
The Company classified certain awards that will be settled in cash as liability awards. The fair value of a liability-classified award is determined on a quarterly basis beginning at the grant date until final vesting. Changes in the fair value of liability-classified awards are expensed or capitalized based on the nature of the employee’s activities over the vesting period of the award.
Litigation Contingencies
We are involved in legal proceedings, claims, and regulatory, tax or government inquiries and investigations that arise in the ordinary course of business. Certain of these matters include speculative claims for substantial or indeterminate amounts of damages. We record a liability when we believe that it is both probable that a loss has been incurred and the amount can be reasonably estimated. If we determine that a loss is reasonably possible and the loss or range of loss can be estimated, we disclose the possible loss in the notes to the consolidated financial statements.
We review the developments in our contingencies that could affect the amount of the provisions that has been previously recorded, and the matters and related possible losses disclosed. We make adjustments to our prior period amounts inprovisions and changes to our operatingdisclosures accordingly to reflect the impact of negotiations, settlements, rulings, advice of legal counsel, and investing sections on our Consolidated Statements of Cash Flows in accordance with ASU No. 2016-9, which amends ASC Topic 718, “Compensation— Stock Compensation.” See “— Accounting Pronouncements” below.updated information. Significant judgement is required to determine both the probability and the estimated amount.
Foreign Currency Translation
Although we are a UK company, our functional currency is the U.S. dollar, and we define any non-U.S. dollar denominated currency as “foreign currencies”. In non-U.S. locations where the U.S. Dollar has been designated as the functional currency (based on an evaluation of factors including the markets in which the subsidiary operates, inflation, generation of cash flow, financing activities and intercompany arrangements), local currency transaction gains and losses are included in net income or loss. In non-U.S. locations where the local currency is the functional currency, assets and liabilities are translated at the rates of exchange on the balance sheet date, while statement of operations items are translated at average rates of exchange during the year. The resulting gains or losses arising from the translation of accounts from the functional currency to the U.S. Dollar are included in “Accumulated other comprehensive loss” in the Consolidated Balance Sheets. We did not recognize any material gains or losses on foreign currency transactions or translations during the three years ended December 31, 2017.
Cash and Cash Equivalents
Cash and cash equivalents include cash on hand, demand deposits with banks and all highly liquid investments with original maturities of three months or less. Our cash, cash equivalents and short-term investments are subject to potential credit risk, and certain of our cash accounts carry balances greater than the federally insured limits. Cash and cash equivalents are primarily held by major banks or investment firms. Our cash management and investment policies restrict investments to lower risk, highly liquid securities and we perform periodic evaluations of the relative credit standing of the financial institutions with which we conduct business.

Accounts Receivable
We record accounts receivable at the amount we invoice our clients, net of allowance for doubtful accounts. We provide an allowance for uncollectible accounts, as necessary. Our allowance for doubtful accounts as of December 31, 2017 and 2016 was $20.8 million, respectively.
Property and Equipment
Property and equipment is stated at cost, reduced by provisions to recognize economic impairment. Major replacements and improvements are capitalized. When assets are sold, retired or otherwise disposed of, the cost and related accumulated depreciation are eliminated from the accounts and the gain or loss is recognized. Drilling equipment and facilities are depreciated using the straight-line method over their estimated useful lives as of the date placed in service or date of major refurbishment. Estimated useful lives of our drilling equipment range from three to thirty years. Other property and equipment is depreciated using the straight-line method over useful lives ranging from two to forty years. Included in accounts payable were $21.0 million and $25.8 million of capital accruals as of December 31, 2017 and 2016, respectively.
Interest is capitalized on long-term construction project using the weighted average cost of debt outstanding during the period of construction.
Scheduled maintenance of equipment is performed based on the number of hours operated in accordance with our preventative maintenance program. Routine repair and maintenance costs are charged to expense as incurred; however, the costs of the overhauls and asset replacement projects that benefit future periods and which typically occur every three to five years are capitalized when incurred and depreciated over an equivalent period. These overhauls and asset replacement projects are included in “Drilling equipment and facilities” in “Note 5— Property and Equipment.”
We evaluate property and equipment for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. For more detailed information, see “Note 6— Impairment.”
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 three-level hierarchy, from highest to lowest level of observable inputs, are as follows:
Level 1 - Valuations based on quoted prices in active markets for identical assets;
Level 2 - Valuations based on observable inputs that do not meet the criteria for Level 1, including quoted prices in inactive markets and quoted prices in active markets for similar but not identical instruments; and
Level 3 - Valuations based on unobservable inputs.
Revenue RecognitionShare
Our typical dayrate drilling contract revenue, excluding taxes or duty, require our performance of a variety of services for a specified period of time. We determine progress towards completion of the contract by measuring efforts expended and the cost of services requiredunvested share-based payment awards, which contain non-forfeitable rights to perform under a drilling contract, as the basis for our revenue recognition. Revenues generated from our dayrate-basis drilling contracts and labor contractsdividends, are recognized on a per day basis as services are performed and begin upon the contract commencement, as defined under the specified drilling contract. Dayrate revenues are typically earned, and contract drilling expenses are typically incurred ratably over the term of our drilling contracts. We review and monitor our performance under our drilling contracts to confirm the basis for our revenue recognition. Revenues from bonuses are recognized when earned, and when collectability is reasonably assured.
In our dayrate drilling contracts, we typically receive compensation and incur costs for mobilization, equipment modification or other activities prior to the commencement of a contract. Any such compensation may be paid through a lump-sum payment or other daily compensation. Pre-contract compensation and costs are deferred until the contract commences. The deferred pre-contract compensation and costs are amortized, using the straight-line method, into income or loss over the term of the initial contract period, regardless of the activity taking place. This approach is consistent with the economics for which the parties have contracted. Once a contract commences, we may conduct various activities, including drilling and well bore related activities, rig maintenance and equipment installation, movement between well locations or other activities.
Deferred revenues from drilling contracts totaled $114.3 million and $134.4 million at December 31, 2017 and 2016, respectively. Such amounts are included in either “Other current liabilities” or “Other liabilities” in the accompanying Consolidated Balance Sheets, based upon our expected time of recognition. Related expenses deferred under drilling contracts totaled $55.7 million at December 31, 2017 as compared to $72.8

On December 22, 2017, the President of the United States signed The Act into law. The Act represents major tax reform legislation that, among other provisions, reduces the U.S. corporate tax rate. The Company recognized the income tax effects of the Act in its 2017 financial statements, including $109.0 million of tax benefit recorded principally due to the write-down of our net deferred tax liabilities, in accordance with Accounting Standards Codification (“ASC”) Topic 740, Income Taxes, in the reporting period in which the Act was enacted. Based on guidance issued from Staff Accounting Bulletin No. 118 ("SAB 118"), the Company has not provided provisional estimates for items in which the accounting for certain income tax effects of the Act is incomplete and as such, the Company will continue to apply ASC 740 on the basis of the laws in effect immediately before the enactment of the Act. See “Note 10— Income Taxes,” for further information on the financial statement impact of the Act.
The Act introduces a new anti-deferral provision, which subjects a U.S. parent shareholder to current tax on certain income referred to as Global Intangible Low-Taxed Income (“GILTI”), of its foreign subsidiaries. The company has not made any adjustments related to potential GILTI tax in its financial statements and has adopted a policy to treat tax due on future U.S. inclusions in taxable income as period costs when incurred.

Certain Significant Estimates
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period. Certain accounting policies involve judgments and uncertainties to such an extent that there is reasonable likelihood that materially different amounts could have been reported under different conditions, or if different assumptions had been used. We evaluate our estimates and assumptions on a regular basis. We base our estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates and assumptions used in preparation of our consolidated financial statements.
Accounting Pronouncements
Accounting Standards Adopted
In MarchAugust 2018, the FASB issued Accounting Standards Update (“ASU”) No. 2018-14, which amends Accounting Standards Codification (“ASC”) Subtopic 715-20, “Compensation — Retirement Benefits — Defined Benefit Plans — General.” This update applies to all employers that sponsor defined benefit pension or other postretirement plans and is part of the disclosure framework project to improve the effectiveness of disclosures in notes to the financial statements. The amendment is effective for fiscal years ending after December 15, 2020. We adopted this standard effective January 1, 2020 and our adoption did not have a material effect on our consolidated financial statements.
In June 2016, the FASB issued ASU No. 2016-9,2016-13 (Topic 326, “Measurement of Credit Losses on Financial Instruments”), which amends ASC Topic 718, “Compensation – Stock Compensation.”requires changes to the recognition of credit losses on financial instruments not accounted for at fair value through net income, including loans, debt securities, trade receivables, net investments in leases and available-for-sale debt securities. This amendment simplifies several aspects of the 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. This standardguidance is effective for interimannual and annual reportinginterim periods beginning after December 31, 2016 and we adopted15, 2019. Entities are required to apply the standardstandard’s provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is adopted. We adopted this standard effective January 1, 2017. Under the new provision, current period excess tax benefits related to stock compensation are now recognized in2020 and our Consolidated Statement of Operations in “Provision for income taxes,” rather thanadoption did not have a material effect on our Consolidated Balance Sheet and Consolidated Statement of Cash Flows. This update has been applied on a prospective basis. Changes to our Consolidated Statement of Cash Flows related to the reclassification of prior period excess tax benefits and employee taxes paid for share-based payment arrangements have been implemented on a retrospective basis. In accordance with our adoption of this update, prior period excess tax benefits of approximately $5.5 million and $1.6 million, previously classified as a financing activity in “Employee stock transactions” in the Consolidated Statement of Cash Flows for the year ended December 31, 2016 and 2015, respectively, are now classified as an operating activity in “Net change in other assets and liabilities” on the accompanying Consolidated Statement of Cash Flows for the comparative periods. Additionally, prior period employee taxes paid for share-based payment arrangements of approximately $3.2 million and $4.1 million, previously classified as an operating activity in “Net change in other assets and liabilities” in the Consolidated Statement of Cash Flows for the year ended December 31, 2016 and 2015, respectively, are now classified as a financing activity in “Employee stock transactions” on the accompanying Consolidated Statement of Cash Flows for the comparative periods.

Recently Issued Accounting Standards
In May 2014,December 2019, the FASB issued ASU No. 2014-9, which creates Accounting Standards Codification (“ASC”) Topic 606, “Revenue from Contracts with Customers,” and supersedes the revenue recognition requirements in Topic 605, “Revenue Recognition,” including most industry-specific revenue recognition guidance throughout the Industry Topics of the Codification. In addition, ASU No. 2014-9 supersedes the cost guidance in Subtopic 605-35, “Revenue Recognition—Construction-Type and Production-Type Contracts,” and creates new Subtopic 340-40, “Other Assets and Deferred Costs—Contracts with Customers.” In summary, the core principle of Topic 606 is to recognize revenue when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. The amendments in ASU No. 2014-9 are effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period, and early application is permitted for periods beginning after December 15, 2016. We have formed an implementation work team, completed training on ASC Topic 606 and are finishing a project to review relevant contracts. We have adopted the new standard effective January 1, 2018 under the modified retrospective approach. With respect to our revenue recognized, as of December 31, 2017, we have qualitatively assessed that the effect of adoption will have an impact to deferred revenues in either “Other current liabilities” or “Other liabilities”, to revenues recorded in excess of billings recorded in “Prepaid expenses and other current assets,” and the net impact recorded to “Retained earnings” on our accompanying Consolidated Balance Sheets. Quantitatively, we estimate that the effect of our retrospective adoption will be immaterial. Therefore, with respect to our modified retrospective adoption, we do not anticipate a change to our financial presentation on our Consolidated Balance Sheets as of December 31, 2017.
In February 2016, the FASB issued ASU No. 2016-2, which creates ASC Topic 842, “Leases.” This update increases transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. This standard is effective for interim and annual reporting periods beginning after December 15, 2018. Our adoption, and the ultimate effect on our consolidated financial statements, will be based on an evaluation of the contract-specific facts and circumstances. We expect to adopt ASC 842 effective January 1, 2019. We expect to apply the modified retrospective approach to our adoption. Our adoption will have an impact on how our consolidated financial statements and related disclosures will be presented. With respect to leases whereby we are the lessee, we are currently expecting to recognize lease liabilities and offsetting “right of use” assets upon adoption. We are currently evaluating any other impacts ASC 842, including any newly issued guidance, will have on our consolidated financial statements and related disclosures. To facilitate that evaluation, we have completed training on the ASU, formed an implementation team and started the review and documentation of contracts.
In October 2016, the FASB issued ASU No. 2016-162019-12, which amends ASC Topic 740, “Income Taxes.” The amendments in thisTaxes” This update improvesimplifies the accounting for the income tax consequences of intra-entity transfers of assets other than inventory. This standard is effective for interim and annual reporting periods beginning after December 15, 2017 and will be applied on a modified retrospective basis. As a result of the modified retrospective application, we will reduce “Other assets” in our Consolidated Balance Sheet with a cumulative adjustmenttaxes by removing certain exceptions to retained earnings of approximately $148.0 million as of January 1, 2018.
In February 2017, the FASB issued ASU No. 2017-6, which amends ASC Topic 960, “Defined Benefit Pension Plans,” ASC Topic 962, “Defined Contribution Pension Plans” and ASC Topic 965, “Health and Welfare Benefit Plans.”general principles. The amendments in this update clarify presentation requirements for an employee benefit plan’s interest in a master trust and require more detailed disclosures of the plan’s interest in the master trust. The amendments also eliminate a redundancy relating to 401(h) account disclosures. This standardamendment is effective for fiscal years beginning after December 15, 2018, with early application permitted.2020 and is required to be adopted on a retrospective basis for all periods presented. We are evaluating what impact, if any,do not expect the adoption of this guidance will have onto materially affect our consolidated financial condition, results of operations, cash flows or financial disclosures.
In February 2018, the FASB issued ASU No. 2018-2, which amends ASC Topic 220, “Income Statement—Reporting Comprehensive Income.” The amendments in this update allow for a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Act. This standard is effective for interim and annual reporting periods beginning after December 15, 2018; however, we expect to early adopt ASC 220 effective January 1, 2018. The amendment should be applied on a retrospective basis to each period in which the effect of the change in the U.S. federal corporate income tax rate in the Act is recognized. As a result of the retrospective application, we will reduce “Accumulated Other Comprehensive Income” with a cumulative adjustment to “Retained Earnings” of approximately $5.5 million as of January 1, 2018.statements.
With the exception of the updated standards discussed above, there have been no new accounting pronouncements not yet effective that have significance, or potential significance, to our consolidated financial statements.

Note 2— Chapter 11 Proceedings
Bankruptcy Petition and Emergence
On the Petition Date, Legacy Noble and certain of its subsidiaries, including Finco, filed voluntary petitions in the Bankruptcy Court seeking relief under chapter 11 of the Bankruptcy Code. In September 2020, the Debtors filed the Plan and the Disclosure Statement with the Bankruptcy Court and 6 additional subsidiaries of Legacy Noble filed voluntary petitions in the Bankruptcy Court. During the proceedings, the Debtors operated their business as “debtors-in-possession” under the jurisdiction of the Bankruptcy Court pursuant to sections 1107 and 1108 of the Bankruptcy Code and orders of the Bankruptcy Court. To ensure the Debtors’ ability to continue operating in the ordinary course of business, on August 3, 2020, the Bankruptcy Court entered a variety of orders providing “first day” relief to the Debtors, including the authority for the Debtors to continue using their cash management system, pay employee wages and benefits and pay vendors and suppliers in the ordinary course of business. As of the Petition Date, the Company began applying ASC Topic 852, Reorganizations (“ASC 852”).
The filing of the Chapter 11 Cases constituted events of default that accelerated the Company’s obligations under the indentures governing its outstanding senior notes and under our 2017 Credit Facility. In addition, the unpaid principal and interest due under our then-outstanding senior notes and 2017 Credit Facility became immediately due and payable. As of December 31, 2020, the estimated claim amounts of our senior notes and the 2017 Credit Facility have been presented as “Liabilities subject to compromise” in our Consolidated Balance Sheet. However, any efforts to enforce such payment obligations with respect to such senior notes and 2017 Credit Facility were automatically stayed as a result of the filing of the Chapter 11 Cases, and the creditors’ rights of enforcement were subject to the applicable provisions of the Bankruptcy Code. As of December 31, 2020, we had an aggregate outstanding principal amount of approximately $3.4 billion in senior notes with stated maturities at various times from 2020 through 2045 and $545.0 million of borrowings outstanding under our 2017 Credit Facility. We elected not to make the semiannual interest payment due in respect of our Senior Notes due 2024 (the “2024 Notes”), which was due on July 15, 2020, and did not make any additional interest payments due on any senior notes through the Effective Date.
As a result of the filing of the Chapter 11 Cases, Legacy Noble’s Board of Directors determined to cancel Legacy Noble’s share ownership policy applicable to the officers and directors, and the Company will consider an appropriate policy in due course.
On the Petition Date, the Debtors entered into a Restructuring Support Agreement (together with all exhibits and schedules thereto, and as amended by the First Amendment thereto dated as of August 20, 2020, the “Restructuring Support Agreement”) with an ad hoc group of certain holders of approximately 70% of the aggregate outstanding principal amount of the outstanding Senior Notes due 2026 (the “Guaranteed Notes”) and an ad hoc group of certain holders of approximately 45% of the aggregate principal amount of our other then-outstanding senior notes, taken as a whole (the “Legacy Notes”). Legacy Noble entered into a Backstop Commitment Agreement (the “Backstop Commitment Agreement”) with the backstop parties thereto (the “Backstop Parties”) on October 12, 2020, pursuant to which the issuance of the senior secured second lien notes (the “Second Lien Notes”) as part of the rights offering contemplated by the Restructuring Support Agreement and the Plan (the “Rights Offering”) were fully backstopped by the Ad Hoc Guaranteed Group and the Ad Hoc Legacy Group (each as defined in the Restructuring Support Agreement). Participation in the Rights Offering was offered to the holders of the Guaranteed Notes and the Legacy Notes.
The Restructuring Support Agreement, among other things, provides that the Consenting Creditors (as defined in the Restructuring Support Agreement) will support the Debtors' restructuring efforts as set forth in, and subject to the terms and conditions of, the Restructuring Support Agreement. The Restructuring Support Agreement contains customary conditions, representations, and warranties of the parties and is subject to a number of conditions, including, among others, the accuracy of the representations and warranties of the parties and compliance with the obligations set forth in the Restructuring Support Agreement. The Restructuring Support Agreement also provides for termination by the parties upon the occurrence of certain events.
On the Effective Date, and pursuant to the terms of the Plan, the Company:
Appointed 5 new members to the Successor’s board of directors to replace all of the directors of the Predecessor, other than the director also serving as President and Chief Executive Officer, who was re-appointed pursuant to the Plan;
Terminated and cancelled all common stock and equity-based awards of Legacy Noble that were outstanding immediately prior to the Effective Date;
Transferred approximately 31.7 million ordinary shares of Noble with a nominal value of $0.00001 per share data)(“New Shares”) to holders of the Guaranteed Notes in the cancellation of the Guaranteed Notes;

Transferred approximately 2.1 million New Shares, approximately 8.3 million seven-year warrants with Black-Scholes protection (the “Tranche 1 Warrants”) with an exercise price of $19.27 and approximately 8.3 million seven-year warrants with Black-Scholes protection (the “Tranche 2 Warrants”) with an exercise price of $23.13 to holders of the Legacy Notes in cancellation of the Legacy Notes;

Entered into an exchange agreement with certain Backstop Parties which provided that, as soon as reasonably practicable after the Effective Date, the other parties to such agreement would deliver to the Company an aggregate of approximately 6.5 million New Shares issued pursuant to the Plan in exchange for the issuance of penny warrants to purchase up to approximately 6.5 million New Shares, with an exercise price of $0.01 per share (“Penny Warrants”) which were exchanged on a 1-for-one basis for New Shares issued to certain initial holders of New Shares;
Entered into an indenture governing the Second Lien Notes;
Entered into a registration rights agreement with certain parties who received New Shares under the Plan; and
Entered into a registration rights agreement with certain parties who received Second Lien Notes under the Plan.
Management Incentive Plan. The Plan contemplated that on or after the Effective Date, (i) the Company would adopt a long-term incentive plan and authorize and reserve 7.7 million New Shares for issuance pursuant to equity incentive awards to be granted under such plan, and (ii) the initial awards under such plan would consist of at least 40% of such shares and be made as soon as practicable after the Effective Date on the terms and conditions as determined by Noble’s Board of Directors; provided that at least 40% of such initial awards would be in the form of time-based vesting awards vesting over a period of no shorter than three years and no longer than four years. As contemplated by the Plan, on February 18, 2021, the Company adopted a long-term incentive plan and authorized and reserved 7.7 million New Shares for issuance pursuant to equity incentive awards to be granted under such plan.
Sources of Cash for Plan Distribution. All cash required for payments made by the Company under the Plan on the Effective Date was obtained from cash on hand, proceeds of the Rights Offering, and proceeds of the Exit Credit Facility.
Under ASC Topic 852, fresh start accounting is required upon emergence from Chapter 11 if (i) the value of the assets of the emerging entity immediately before the date of confirmation is less than the total of all post-petition liabilities and allowed claims; and (ii) holders of existing voting shares immediately before confirmation receive less than 50% of the voting shares of the emerging entity. The value of the assets of Legacy Noble immediately before the date of confirmation is expected to be less than the total of all postpetition liabilities and allowed claims. Additionally, the holders of the existing voting shares of Legacy Noble immediately before the date of confirmation held less than 50% of the voting shares of Noble. The same test was performed for Finco and yielded the same result. As such, Noble and Finco will adopt fresh start accounting as of the Effective Date. Adopting fresh start accounting results in a new reporting entity with no beginning retained earnings or accumulated deficit. In accordance with ASC Topic 852, with the application of fresh start accounting, the Company will be required to allocate its reorganization value to its individual assets based on their estimated fair values in conformity with ASC Topic 805, “Business Combinations.” The reorganization value represents the fair value of the Successor Company's assets before considering liabilities. The Company is in the process of evaluating the potential impact of the fresh start accounting on its consolidated financial statements. We cannot currently estimate the financial effect of emergence from bankruptcy on our financial statements, although we expect to record material adjustments related to our Plan and the application of fresh start accounting as of the Effective Date.
The Company’s financial advisor performed a valuation of the reorganized Company dated as of August 24, 2020. According to the valuation, which was included in the Disclosure Statement related to the Plan, the post-confirmation estimated enterprise value of the Company to be in a range between $1.1 billion and $1.6 billion. The following assumptions were made in the valuation of the projected amounts upon emergence; $430.0 million of debt under the Exit Financing Facility and the Second Lien Notes and cash on hand of $100.0 million.

Executory Contracts
Subject to certain exceptions, under the Bankruptcy Code, the Debtors may assume, assign, or reject certain executory contracts and unexpired leases subject to the approval of the Bankruptcy Court and certain other conditions. Generally, the rejection of an executory contract or unexpired lease is treated as a pre-petition breach of such executory contract or unexpired lease and, subject to certain exceptions, relieves the Debtors from performing their future obligations under such executory contract or unexpired lease but entitles the contract counterparty or lessor to a pre-petition general unsecured claim for damages caused by such deemed breach. Typically, the assumption of an executory contract or unexpired lease requires the Debtors to cure existing monetary defaults under such executory contract or unexpired lease and provide adequate assurance of future performance. Accordingly, any description of an executory contract or unexpired lease with the Debtors in this Annual Report on Form 10-K, including where applicable a quantification of the Company’s obligations under any such executory contract or unexpired lease of the Debtors, is qualified by any overriding rejection rights the Company has under the Bankruptcy Code. As of December 31, 2020, the Debtors have rejected 3 immaterial executory contracts and have not rejected any unexpired leases.
Claims Reconciliation
The Debtors have filed with the Bankruptcy Court schedules and statements setting forth, among other things, the assets and liabilities of each Debtor, subject to the assumptions filed in connection therewith. These schedules and statements may be subject to further amendment or modification after filing. Certain holders of pre-petition claims that are not governmental units were required to file proofs of claim by the deadline for general claims, which was set by the Bankruptcy Court as October 6, 2020 and November 13, 2020 for the initial Debtors that filed on July 31, 2020 (the “Initial Debtors”) and the additional Debtors that filed on September 24, 2020 (the “Additional Debtors”), respectively. The governmental bar date has been set as January 27, 2021 and March 23, 2021, for the Initial Debtors and the Additional Debtors, respectively.
The Debtors received approximately 1,200 proofs of claim as of March 5, 2021 for an amount of approximately $23.0 billion. Such amount includes duplicate claims across multiple Debtor legal entities. These claims are being reconciled to amounts recorded in the Debtors’ accounting records. Differences between amounts recorded by the Debtors and claims filed by creditors will be investigated and resolved, at the direction of the Debtors, including through proceedings before the Bankruptcy Court. In addition, the Debtors have been identifying claims that have been amended or superseded, are without merit, are overstated or should be adjusted or expunged for other reasons. As a result of this process, the Debtors may identify additional liabilities that will need to be recorded or reclassified to Liabilities subject to compromise. In light of the number of claims filed, the claims resolution process will continue after the Debtors emerge from bankruptcy.
Pre-petition Charges
Pre-petition charges consist primarily of legal and other professional advisory fees incurred in relation to the Chapter 11 Cases, but prior to the Petition Date, and are presented as “Pre-petition charges” in our Consolidated Statements of Operations for the year ended December 31, 2020.
Reorganization Items, Net
In accordance with ASC Topic 852, any incremental expenses, gains and losses that are realized or incurred as of or subsequent to the Petition Date and as a direct result of the Chapter 11 Cases are recorded under “Reorganization items, net”.

Liabilities Subject to Compromise
Since the Petition Date, the Company operated as a debtor-in-possession under the jurisdiction of the Bankruptcy Court and in accordance with provisions of the Bankruptcy Code. In accordance with ASC 852, on our Balance Sheets, the caption “Liabilities subject to compromise” reflects the expected allowed amount of the pre-petition claims that are not fully secured and that have at least a possibility of not being repaid at the full claim amount. The Company has considered the chapter 11 motions approved by the Bankruptcy Court with respect to the amount and classification of its pre-petition liabilities. However, the determination of the value at which liabilities will ultimately be settled was made on the Effective Date. The Company will evaluate and adjust the amount and classification of its pre-petition liabilities through the Effective Date.

Note 4— Receivables from Customers
At December 31, 2016, we had receivables of approximately $14.4 million related to the Noble Max Smith, which had been disputed by our former customer, Petróleos Mexicanos (“Pemex”) and were classified as long-term and included in “Other assets” on our Consolidated Balance Sheet. The receivables were related to lost revenues for downtime that occurred after our rig was damaged when one of Pemex's supply boats collided with our rig in 2010. A Mexican subsidiary of Paragon Offshore, which had operated the Noble Max Smith, had been prosecuting the claim against Pemex. During the year ended December 31, 2017, Paragon Offshore has announced that, as part of its bankruptcy plan, it will liquidate the Mexican entity involved.
While Noble owns all rights to amounts from that claim and will take available actions to recover such amounts, we believe the announced actions by Paragon Offshore create uncertainty relating to the prosecution of the claim and associated recovery, and accordingly, the disputed amounts of approximately $14.4 million were written off through “Contract drilling services” costs on the accompanying Consolidated Statements of Operations during the year ended December 31, 2017.

For the year ended December 31, 2020, we sold 6 rigs, which had a net book value of $17.1 million for total proceeds of $26.7 million, resulting in a gain of $8.9 million.
Note 6— Loss on Impairment
In connection with the preparation of the consolidated financial statements included in this Annual Report, consistent with our accounting policiesAsset Impairments
As discussed in “Note 1— Organization and Significant Accounting Policies,” during the first quarter of 2020, the pandemic and OPEC+ production level disagreements resulted in an unprecedented steep decline in the demand for oil and a substantial surplus of oil. We considered these events to be an impairment indicator and based on our assumptions and analysis, we evaluate our property and equipment for impairment whenever there are circumstances that suggestimpaired the carrying value of an asset may not be recoverable.4 floaters. For our impaired units, the carrying values were written down to scrap value and subsequently sold in late 2020.
An impairment lossDuring the fourth quarter of 2020, the combination of the growing commitments by many of our customers to a transition to cleaner energy options, and the prolonged impacts of the pandemic, the continued oversupply of offshore drilling units placed further downward pressure on global oil demand and on our property and equipment may exist when the estimated undiscounted cash flowsindustry, potentially lengthening what was already expected to result frombe a slow recovery. We considered these events to be an impairment indicator and based on our assumptions and analysis, we impaired the use of the asset and its eventual disposition are less than its carrying amount. An impairment loss may be recognized when the excess of the asset's carrying value exceeds theof 3 floaters and 9 jackups. We estimated fair value. We estimate the fair value by applying thevalues of these units using a weighting between an income valuation approach and a market approach, utilizing significant unobservable inputs, representative of a Level 3 fair value measurement. Assumptions used in our assessment included, but were not limited to, future marketability of each unit in light of the current market conditions and its current technical specifications, timing of future contract awards and expected operating day rates,dayrates, operating costs, utilization rates, discount rates, capital expenditures, market values, weighting of market values, reactivation costs, and estimated economic useful lives. In addition, if we believe that one of our drilling units is no longer marketable or is otherwise unlikely to return to active service, we may elect to retire the unit and/or sell the unit at a value that may be substantially below its book value,lives and, recognize an impairment charge that reduces the asset’s carrying value to the estimated fair value.
During the years ended December 31, 2017, 2016, and 2015, we recognized a non-cash loss on impairment of $121.6 million, $1.5 billion and $418.3 million, respectively, related toin certain rigs and related capital spares.

During the year ended December 31, 2017, we identified indicators that certain assets in our fleet might not be recoverable. Such indicators included additional customer suspensions of drilling programs, contract cancellations, a further reduction in the number of new contract opportunities, resulting in reduced drilling contracts, andcases, our belief that a drilling unit is no longer marketable and is unlikely to return to service. As a result,service in the near to medium term.
During the quarters ended March 31, 2020 and December 31, 2020, we determinedrecognized non-cash losses on impairment of $1.1 billion and $2.8 billion, respectively, related to certain rigs and related capital spares. If we experience prolonged unfavorable changes to current market conditions, reactivation costs or dayrates or if we are unable to secure new or extended contracts for our rigs, it is reasonably possible that the carrying amountsestimate of undiscounted cash flows may change in the near term, resulting in the need to write down the affected assets to their corresponding estimated fair values. The impact of the Noble Amos Runner, Noble Alan Hay, NobleDavid Tinsleycurrent global economic turmoil on our customers’ and certain capital spares were impaired and recorded an impairment charge of approximately $121.6 million.
our business continues to be uncertain. During the year ended December 31, 2016,2020, we recognized approximately $3.9 billion in connection withimpairment charges for 7 floaters and 9 jackups, and $24.0 millionofimpairment charges related to certain capital spare equipment.
Based upon our impairment analysis, we impaired the carrying values to their corresponding estimated fair values for the Noble Amos Runner, Noble Clyde Boudreaux and Noble Dave Beard and recorded a charge of $1.0 billion related to these units. In addition, we concluded that the semisubmersible, the Noble Homer Ferrington,2 floaters, and certain capital spare equipment, would not be utilizedwhich resulted in the foreseeable future, and we recognized impairment charges of approximately $120.1 million and $170.5 million, respectively. Further, we decided to retire our semisubmersible, Noble Max Smith, which was sold for $1.2 million after we recognized an impairment charge during the year of approximately $164.8 million.
During the year ended December 31, 2015, we decided that we would no longer market one of our drillships, the Noble Discoverer. The decision was a result of the termination of the contract for this rig by Shell in December 2015 and the decreased opportunities for rigs of this type in the current marketplace. We also reviewed assumptions on the future marketability of one of our jackups, the Noble Charles Copeland, after its contract completion in late September 2015, with consideration given to its years in service, limited technical features and anticipated capital requirements in light of the current market conditions, and we decided to discontinue marketing this unit. Additionally, based upon an analysis of capital spare equipment, we elected to retire certain capital spare equipment. Accordingly, we recorded an impairment charge of $406.0approximately $615.3 million for the year ended December 31, 20152019. During the year ended December 31, 2019, we recognized a $595.5 million impairment on the Noble Bully II, of which $265.0 million was attributable to our joint venture partner at the time of impairment. See “Note 3— Consolidated Joint Ventures” for additional information. For our impaired units, we estimated the fair value of these units by applying the income valuation approach utilizing significant unobservable inputs, representative of a Level 3 fair value measurement. If we experience unfavorable changes to current market conditions, reactivation costs or dayrates, or we are unable to return cold stacked rigs to service in the anticipated time frame or if we are unable to secure new or extended contracts for our active rigs, it is reasonably possible that the estimate of undiscounted cash flows may change in the near term, resulting in the need to write down the affected assets to their corresponding estimated fair values.
Based upon our impairment analysis, we impaired the carrying values to their corresponding estimated fair values for 3 floaters and 2 jackups, and certain capital spares.spare equipment. During the year ended December 31, 2018, impairment charges related to these units and certain capital spare equipment were approximately $802.1 million. For our impaired units, we estimated the fair values of these units by applying the income valuation approach utilizing significant unobservable inputs, representative of a Level 3 fair value measurement. During the year ended December 31, 2018, we recognized a $550.3 million impairment on the Noble Bully I, of which $250.3 million was attributable to our joint venture partner at the time of impairment.

Credit Facilities and Commercial Paper Program
2015 Credit Facility
At December 31, 2017, we had a five-year $2.4 billion senior unsecured credit facility that matures in January 2020 and which is guaranteed by our indirect, wholly owned subsidiaries, Noble Holding (U.S.) LLC (“NHUS”) and Noble Holding International Limited (“NHIL”) (the “2015 Credit Facility”). The 2015 Credit Facility also provided us with the ability to issue up to $500.0 million in letters of credit. The issuance of letters of credit under the facility reduces the amount available for borrowing. At December 31, 2017, we had no borrowings outstanding or letters of credit issued under our 2015 Credit Facility.
On December 19, 2017, we entered into the First Amendment and Consent and Successor Agent Agreement, (the “Amendment”) amending the 2015 Credit Facility. Upon certain conditions, including the entering into of the Company's 2017 Credit Facility (as defined below), the Amendment provides for, on or after January 3, 2018, among other things (i) a reduction in the aggregate principal amount of commitments under the 2015 Credit Facility to $300.0 million and (ii) the reduction of the 2015 Credit Facility's letter of credit subfacility to zero dollars. The maturity of the 2015 Credit Facility remains January 2020.Pre-emergence Debt

In July 2019, we executed a first amendment to our 2017 Credit Facility, which, among other things, reduced the “Credit Facilities”). The maximum aggregate amount of borrowings undercommitments thereunder from $1.5 billion to $1.3 billion. As a result of such reduction in the maximum aggregate amount of commitments, we recognized a net loss of approximately $0.7 million in the year ended December 31, 2019.
Prior to the filing of the Chapter 11 Cases, the 2017 Credit Facility of $1.5 billion becamewas scheduled to mature in January 2023. Borrowings were available on January 3, 2018 upon the effectiveness of the commitment reduction under the 2015 Credit Facility. Borrowings under the 2017 Credit Facility are subject to certain conditions precedent, including that there be no unused commitments to advance loans under the 2015 Credit Facility.for working capital and other general corporate purposes.

The 2017 Credit Facility has an initial maturity of up to five years from the date on which the borrowings became available, or January 3, 2023. At December 31, 2017, we had no borrowings outstanding or letters of credit issued under the 2017 Credit Facility.

The filing of the Chapter 11 Cases constituted events of default that accelerated the Company’s obligations under the indentures governing our outstanding senior notes and under our 2017 Credit FacilitiesFacility. In addition, the unpaid principal and interest due under our indentures and the 2017 Credit Facility became immediately due and payable. However, any efforts to enforce such payment obligations with respect to our senior notes and 2017 Credit Facility were automatically stayed as a result of the filing of the Chapter 11 Cases, and the creditors’ rights of enforcement were subject to the applicable provisions of the Bankruptcy Code. See “Note 1— Organization and Basis of Presentation” for additional information.
On the Effective Date, all outstanding obligations under the 2017 Credit Facility were terminated and the holders of claims under the 2017 Credit Facility had such obligations refinanced through the Exit Credit Facility. On the Effective Date, all liens and security interests granted to secure such obligations were terminated and are of no further force and effect.
2015 Credit Facility
Effective January 2018, in connection with entering into the highest permitted2017 Credit Facility, we amended our $300.0 million senior unsecured credit facility that would have matured in January 2020 and was guaranteed by our indirect, wholly-owned subsidiaries, Noble Holding (U.S.) LLC and Noble Holding International Limited (“NHIL”), a finance subsidiary of Finco, (as amended, the “2015 Credit Facility”). As a result of the 2015 Credit Facility's reduction in the aggregate principal amount of commitments, we recognized a net loss of approximately $2.3 million in the year ended December 31, 2018. On December 20, 2019, we repaid $300.0 million of outstanding borrowings and terminated the 2015 Credit Facility.
Seller Loans
In February 2019, we purchased the Noble Joe Knight for $83.8 million with a $53.6 million seller-financed secured loan (the “2019 Seller Loan”). The 2019 Seller Loan had a term of four years and required a 5% principal payment at the end of the third year with the remaining 95% of the principal due at the end of the term. The 2019 Seller Loan bore a cash interest rates under those agreements.rate of 4.25% and the equivalent of a 1.25% interest rate paid-in-kind over the four-year term of the 2019 Seller Loan. Based on the terms of the 2019 Seller Loan, the 1.25% paid-in-kind interest rate was accelerated into the first year, resulting in an overall first year interest rate of 8.91%, of which only 4.25% was payable in cash. Thereafter, the paid-in-kind interest ended and the cash interest rate of 4.25% was payable for the remainder of the term.
In September 2018, we purchased the Noble Johnny Whitstine for $93.8 million with a $60.0 million seller-financed secured loan (the “2018 Seller Loan” and, together with the 2019 Seller Loan, the “Seller Loans”).

Based on the terms of the 2018 Seller Loan, the 1.25% paid-in-kind interest rate was accelerated into the first year, resulting in an overall first year interest rate of 8.91%, of which only 4.25% was payable in cash. Thereafter, the paid-in-kind interest ended and the cash interest rate of 4.25% was payable for the remainder of the term.
Debt IssuancesBoth of the Seller Loans were guaranteed by Finco and each was secured by a mortgage on the applicable rig and by the pledge of the shares of the applicable single-purpose entity that owned the relevant rig. Each Seller Loan contained a debt to total capitalization ratio requirement that such ratio not exceed 0.55 at the end of each fiscal quarter, a $300.0 million minimum liquidity financial covenant and an asset and revenue covenant substantially similar to the Guaranteed Notes, as well as other covenants and provisions customarily found in secured transactions, including a cross-default provision. Each Seller Loan required immediate repayment on the occurrence of certain events, including the termination of the drilling contract associated with the relevant rig or circumstances in connection with a material adverse effect.
In December 2016, we issued $1.0 billion aggregateApril 2020, the Company agreed with the lender under the Seller Loans to pay off 85% of the outstanding principal amount of the 2024 Notes, whichSeller Loans in exchange for a discount to the outstanding loan balance. On April 20, 2020, the Company made a payment of $48.1 million under the 2019 Seller Loan and $53.6 million under the 2018 Seller Loan, and, upon the lender’s receipt of such payment, interest ceased accruing, and the financial covenants set forth in the agreements relating to the Seller Loans ceased to apply. On July 20, 2020, at the conclusion of the 90-day period following the payment date, all outstanding amounts were reduced to 0, all security was released, and the Seller Loans were terminated.
As a result of the early repayment of the Seller Loans and the conclusion of the 90-day period following the payment date, we issued through our indirect wholly-owned subsidiary, NHIL. The net proceedsrecognized gains of approximately $967.6and $17.3 million after estimated expenses, were primarily usedin the year ended December 31, 2020.

As a result of these downgrades, we experienced interest rate increases during 2017 and 2016 on the 2018 Notes, 2025 Notes and 2045 Notes, all of which are subject to provisions that vary the applicable interest rates based on our debt rating. On October 18, 2017 S&P Global Ratings further reduced our debt rating, which will increase the interest rates on the 2025 Notes and 2045 Notes to 7.95% and 8.95%, respectively, beginning in April 2018. Once the new interest rates take effect in April 2018, these senior notes will have reached the contractually-defined maximum interest rate set for each rating agency and no further interest rate increase will occur.
Our other outstanding senior notes, including the 2024 Notes issued in December 2016, and 2026 Notes issued in January 2018, do not contain provisions varying applicable interest rates based upon our credit ratings.
Debt Tender Offers and Repayments
In March 2017, we repaid our 2017 Notes using cash on hand. We anticipate using cash on hand to repay the outstanding balance of our $300 million 2018 Notes, maturing in March 2018. In February 2018, we completed an optional redemption of our remaining 2019 Notes, which is described further in “Note 19— Subsequent Events.”
In December 2016, we commenced cash tender offers for our 2020 Notes, 2021 Notes and 2022 Notes. On December 28, 2016, we purchased $762.3 million of these Senior Notes for $750.0 million, plus accrued interest, using a portion of the net proceeds of the $1.0 billion 2024 Notes issuance in December 2016. In December 2016, as a result of these tender offers,transactions, we recognized a net gain of approximately $6.7$31.3 million.

Senior Secured Exit Revolving Credit Facility
On the Effective Date, Finco and Noble International Finance Company (“NIFCO”) entered into the Exit Credit Agreement providing for the $675.0 million Exit Credit Facility and canceled all debt that existed immediately prior to the Effective Date. The Exit Credit Facility matures on July 31, 2025. Subject to the satisfaction of certain conditions, Finco may from time to time designate one or more of Finco’s other wholly-owned subsidiaries as additional borrowers under the Exit Credit Agreement (collectively with Finco and NIFCO, the “Borrowers”). As of the Effective Date, $177.5 million of loans were outstanding, and $8.8 million of letters of credit were issued, under the Exit Credit Facility.
All obligations of the Borrowers under the Exit Credit Agreement, certain cash management obligations and certain swap obligations are unconditionally guaranteed, on a joint and several basis, by Finco and certain of its direct and indirect subsidiaries (collectively with the Borrowers, the “Credit Parties”), including a guarantee by each Borrower of the obligations of each other Borrower under the Exit Credit Agreement. All such obligations, including the guarantees of the Exit Credit Facility, are secured by senior priority liens on substantially all assets of, and the equity interests in, each Credit Party, including all of the rigs owned by the Company as of the Effective Date or acquired thereafter and certain assets related thereto, in each case, subject to certain exceptions and limitations described in the Exit Credit Agreement.
The loans outstanding under the Exit Credit Facility bear interest at a rate per annum equal to the applicable margin plus, at Finco’s option, either: (i) the reserve-adjusted LIBOR or (ii) a base rate, determined as the greatest of (x) the prime loan rate as published in the Wall Street Journal, (y) the federal funds effective rate plus 1⁄2 of 1%, and (z) the reserve-adjusted one-month LIBOR plus 1%. The applicable margin is initially 4.75% per annum for LIBOR loans and 3.75% per annum for base rate loans and will be increased by 50 basis points after July 31, 2024, and may be increased by an additional 50 basis points under certain conditions described in the Exit Credit Agreement.
The Borrowers are required to pay a quarterly commitment fee to each lender under the Exit Credit Agreement, which accrues at a rate per annum equal to 0.50% on the average daily unused portion of such lender’s commitments under the Exit Credit Facility. The Borrowers are also required to pay customary letter of credit and fronting fees.
Borrowings under the Exit Credit Agreement may be used for working capital and other general corporate purposes. Availability of borrowings under the Exit Credit Agreement is subject to the satisfaction of certain conditions, including restrictions on borrowings if, after giving effect to any such borrowings and the application of the proceeds thereof, (i) the aggregate amount of Available Cash (as defined in the Exit Credit Agreement) would exceed $100 million, (ii) the Consolidated First Lien Net Leverage Ratio (as defined in the Exit Credit Agreement) would be greater than 5.50 to 1.00 and the aggregate principal amount outstanding under the Exit Credit Facility would exceed $610 million, or (iii) the Asset Coverage Ratio (as described below) would be less than 2.00 to 1.00.
Mandatory prepayments and, under certain circumstances, commitment reductions are required under the Exit Credit Facility in connection with (i) certain asset sales, asset swaps and events of loss (subject to reinvestment rights if no event of default exists) and (ii) certain debt issuances. Available Cash in excess of $150 million is also required to be applied periodically to prepay loans (without a commitment reduction). The loans under the Exit Credit Facility may be voluntarily prepaid, and the commitments thereunder voluntarily terminated or reduced, by the Borrowers at any time without premium or penalty, other than customary breakage costs.
The Exit Credit Agreement obligates Finco and its restricted subsidiaries to comply with the following financial maintenance covenants:
as of the last day of each fiscal quarter in 2021, Adjusted EBITDA (as defined in the Exit Credit Agreement) is not permitted to be lower than (i) $70 million for the four fiscal quarter period ending March 31, 2021, (ii) $40 million for the four fiscal quarter period ending June 30, 2021 and (iii) $25 million for the four fiscal quarter periods ending on each of September 30, 2021 and December 31, 2021;
as of the last day of each fiscal quarter ending on or after March 31, 2022, the ratio of Adjusted EBITDA to Cash Interest Expense (as defined in the Exit Credit Agreement) is not permitted to be less than (i) 2.00 to 1.00 for each four fiscal quarter period ending on or after March 31, 2022 until June 30, 2024, and (ii) 2.25 to 1.00 for each four fiscal quarter period ending thereafter; and
for each fiscal quarter ending on or after June 30, 2021, the ratio of (x) Asset Coverage Aggregate Rig Value (as defined in the Exit Credit Agreement) to (y) the aggregate principal amount of loans and letters of credit outstanding under the Exit Credit Facility (the “Asset Coverage Ratio”) as of the last day of any such fiscal quarter is not permitted to be less than 2.00 to 1.00.
The Exit Credit Facility contains affirmative and negative covenants, representations and warranties and events of default that the Company considers customary for facilities of this type.

Share-Based Compensation Plans
Stock Plans
During 2015, Noble Corporation plc shareholders approved a new equity plan, the Noble Corporation plc 2015 Omnibus Incentive Plan (the “2015“Noble Incentive Plan”), which permits grants of options, stock appreciation rights (“SARs”), stock or stock unit awards or cash awards, any of which may be structured as a performance award, from time to time to employees who are to be granted awards under the 2015Noble Incentive Plan. Neither consultants nor non-employee directors are eligible for awards under the 2015Noble Incentive Plan. The Noble Incentive Plan replaced the Noble Corporation 1991 Stock Options and Restricted Stock Plan, as amended (the “1991 Plan”). The 1991 Plan was terminated, and equity awards have thereafter only been made under the Noble Incentive Plan. Stock option awards previously granted under the 1991 Plan remain outstanding in accordance with their terms.
During 20172020, 2019 and 2016,2018, the 2015Noble Incentive Plan was restated and shareholders approved amendments, primarily to increase the number of ordinary shares available for issuance as long-term incentive compensation under the 2015Noble Incentive Plan by 3.78.7 million, 5.8 million and 9.55.0 million shares, respectively. The maximum aggregate number of ordinary shares that may be granted for any and all awards under the 2015Noble Incentive Plan will not exceed 20.5 40.0 million shares and at December 31, 2017,2020, we had 10.425.0 million shares remaining available for grants to employees.
The Noble Corporation 1991 Stock Option and Restricted Stock Plan, as amended (the “1991 Plan”), provides for the granting of options to purchase our shares, with or without stock appreciation rights, and the awarding of restricted shares or units to selected employees. Upon shareholder approval of the 2015 Incentive Plan, as described above, the 1991 Plan was terminated and equity based awards to employees are now made only through the 2015 Incentive Plan. Equity based awards previously granted under the 1991 Plan remain outstanding in accordance with their terms, which include the 1991 Plan.
Prior to 2017, we used the Noble Corporation 1992 Nonqualified Stock Options and Share Plan for Non-Employee Directors (the “1992 Plan”), to issue stock awards to non-employee directors.

The fair value of each option is estimated on the date of grant using a Black-Scholes pricing model. The expected term of options granted represents the period of time that the options are expected to be outstanding and is derived from historical exercise behavior, current trends and values derived from lattice-based models. Expected volatilities are based on implied volatilities of traded options on our shares, historical volatility of our shares, and other factors. The expected dividend yield is based on historical yields on the date of grant. The risk-free rate is based on the U.S.US Treasury yield curve in effect at the time of grant.

The market-based PVRSUs are valued on the date of grant based on the estimated fair value. Estimated fair value is determined based on numerous assumptions, including an estimate of the likelihood that our stock price performance will achieve the targeted thresholds and the expected forfeiture rate. The fair value is calculated using a Monte Carlo Simulation Model. The assumptions used to value the PVRSUs include historical volatility and risk-free interest rates over a time period commensurate with the remaining term prior to vesting, as follows:

Liability-Classified Cash Incentive Awards
In February 2018, 603,440 PVRSUs2020, the Company granted cash incentive awards that vest over a three-year period and the final cash payment depends on the degree of achievement of specified corporate performance criteria over a three-year performance period. These criteria consist of market based criteria or market and performance based criteria. These awards were valued on the date of grant based on the estimated fair value. Estimated fair value is determined based on numerous assumptions, including an estimate of the likelihood that our stock price performance will achieve the targeted thresholds and the expected forfeiture rate. The fair value is calculated using a Monte Carlo Simulation Model. The assumptions used to value the awards include historical volatility of 69.8% and a risk-free interest rate of 1.4% over a time period commensurate with the remaining term prior to vesting. Additionally, similar assumptions were made for each of the 2015-2017 performance period were forfeited.companies included in the defined index and the peer group of companies in order to simulate the future outcome using the Monte Carlo Simulation Model.

Contract Costs
Certain direct and incremental costs incurred for upfront preparation, initial rig mobilization and modifications are costs of fulfilling a contract and are recoverable. These recoverable costs are deferred and amortized ratably to contract drilling expense as services are rendered over the initial term of the related drilling contract. Certain of our contracts include capital rig enhancements used to satisfy our performance obligations. These capital items are capitalized and depreciated in accordance with our existing property and equipment accounting policy.
Costs incurred for the demobilization of rigs at contract completion are recognized as incurred during the demobilization process. Costs incurred for rig modifications or upgrades required for a contract, which are considered to be capital improvements, are capitalized as drilling and other property and equipment and depreciated over the estimated useful life of the improvement.

Total$34,544 $15,228 $9,199 $915 $$59,886 
The revenue included above consists of expected mobilization, demobilization, and upgrade revenue for unsatisfied performance obligations. The amounts are derived from the specific terms within drilling contracts that contain such provisions, and the expected timing for recognition of such revenue is based on the estimated start date and duration of each respective contract based on information known at December 31, 2020. The actual timing of recognition of such amounts may vary due to factors outside of our control. We have taken the optional exemption, permitted by accounting standards, to exclude disclosure of the estimated transaction price related to the variable portion of unsatisfied performance obligations at the end of the reporting period, as our transaction price is based on a single performance obligation consisting of a series of distinct hourly, or more frequent, periods, the variability of which will be resolved at the time of the future services.

Note 10—11— Leases
Leases
We determine if an arrangement is a lease at inception. Our operating lease agreements are primarily for real estate, equipment, storage, dock space and automobiles and are included within “Other current liabilities,” “Other assets” and “Other liabilities,” on our Consolidated Balance Sheets. As discussed in “Note 1— Organization and Basis of Presentation,” since the Petition Date, the Company operated as a debtor-in-possession under the jurisdiction of the Bankruptcy Court and in accordance with provisions of the Bankruptcy Code. Accordingly, all of the leases liabilities on the Debtor companies have been presented as “Liabilities subject to compromise” on our Consolidated Balance Sheet at December 31, 2020.
As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. Certain of our lease agreements include options to extend or terminate the lease, which we do not include in our minimum lease terms unless management is reasonably certain to exercise and reasonably certain not to exercise, respectively.
In early January 2021, the Company entered into agreements to surrender a portion of the Sugar Land office lease and to terminate the Brook Street London office leases with the respective lessors. This will reduce the Right of Use Asset and Lease Liability by approximately $11.3 million and $11.9 million, respectively.

Note 12— Income Taxes
Noble-UK is a company whichLegacy Noble is a tax resident in the UK and, as such, will beis subject to UK corporation tax on its taxable profits and gains. A UK tax exemption is available in respect of qualifying dividends income and capital gains related to the sale of qualifying participations. We operate in various countries throughout the world, including the United States. The income or loss of the non-UK subsidiaries is not expected to be subject to UK corporation tax. Prior to the redomiciliation, Noble-Swiss was the group holding company and was exempt from Swiss cantonal and communal income tax on its worldwide income or loss, and was also granted participation relief from Swiss federal tax for qualifying dividend income and capital gains related to the sale of qualifying participations. It is expected that the participation relief will result in a full exemption of participation income from Swiss federal income tax. We do not expect the redomiciliation from Switzerland to the UK to have a material impact on our effective tax rate.
Consequently, we have taken account of those tax exemptionsthe above exemption and provided for income taxes based on the laws and rates in effect in the countries in which operations are conducted, or in which we or our subsidiaries have a taxable presence for income tax purposes.

The changes to existing U.S. tax law as a result of the Act, which had an impact on the Company's federal income taxes for 2017, are as follows:

The Act reduces the federal corporate income tax rate to 21% from 35% effective January 1, 2018. Accordingly, the Company recorded a financial statement benefit of $109.0 million as a result of the remeasurement of its net deferred tax liabilities during the quarter ended December 31, 2017.
The Act provides for a Deemed Repatriation Transition Tax (the “Transition Tax”), which is a one-time tax on previously untaxed accumulated earnings and profits (“E&P”) of certain foreign subsidiaries. For the quarter ended December 31, 2017, no additional income taxes were provided for as the Company has estimated there to be no untaxed accumulated E&P.
The Act provides for immediate an deduction of 100% of the costs of qualified property that is placed in service after September 27, 2017 and before January 1, 2023.The deduction will phase out by 20 percentage points each calendar year for qualified property that is placed in service after December 21, 2022. The company has estimated no material impact from this provision for the quarter ended December 31, 2017.
The estimates above are provisional amounts based on information available as of December 31, 2017. These amounts are subject to changes as we refine our estimates and our interpretation of the Act. Any adjustments to these provisional amounts will be included in the financial statements in the reporting period in which such adjustments are determined, which will be no later than the fourth quarter of 2018.
Other provisions of the Act, which are effective January 1, 2018 and could have an impact on the Company's financial results for 2018 and later periods are as follows:

The Act limits the deduction of business interest to 30% of “adjusted taxable income”, which is taxable income computed without regard to (i) any items not attributable to a trade or business, (ii) business interest income and business interest expense, (iii) any net operating loss deduction, and (iv) for taxable years beginning before January 1, 2022, deductions for depreciation , amortization and depletion. This limitation could result in a deferral or permanent reduction in the amount of interest that is deductible for U.S. federal income tax purposes after 2017.
The Act eliminates the U.S. federal income tax carryback provision for net operating losses (“NOLs”) generated after 2017 and limits the taxpayer's ability to utilize NOL carryforwards to 80% of taxable income. These changes could impact the company's valuation allowance assessment for NOLs generated after December 31, 2017.
The Act includes an anti-base erosion provision which establishes a tax on certain payments made by U.S. corporate taxpayers to related foreign persons, also referred to as Base Erosion and Anti-Abuse Tax (“BEAT”). The company is continuing to gather additional information to determine the ultimate impact of BEAT.
The Act introduces a new anti-deferral provision, which subjects a U.S. parent shareholder to current tax on certain income referred to as GILTI, of its foreign subsidiaries. The company has not made any adjustments related to potential GILTI tax in its financial statements and has adopted a policy to treat tax due on future U.S. inclusions in taxable income as period costs when incurred.

At December 31, 2017,2020, the reserves for uncertain tax positions totaled $191.9$42.5 million (net of related tax benefits of 1.0$0.4 million). If a portion or all of the December 31, 20172020 reserves are not realized, the provision for income taxes wouldcould be reduced by $186.6up to $42.5 million. At December 31, 2016,2019, the reserves for uncertain tax positions totaled $172.5$159.7 million (net of related tax benefits of 1.0$0.4 million).
It is reasonably possible that our existing liabilities related to our reserve for uncertain tax positions may fluctuate in the next 12 months primarily due to the completion of open audits or the expiration of statutes of limitation. However, we cannot reasonablyWe estimate athe potential changes could range up to $14.0 million.
On March 27, 2020, the 45th President of the United States signed the CARES Act into law. The CARES Act makes significant changes in our existing liabilities due to various uncertainties, suchareas of US federal income tax law by, among other things, allowing a five-year carryback period for 2018, 2019 and 2020 NOLs, accelerating the realization of remaining alternative minimum tax credits, and increasing the interest expense limitation under Section 163(j) for years 2019 and 2020. The Company recognized an income tax benefit of $39.0 million as a result of the unresolved natureapplication of various audits.the CARES Act in its 2020 financial statements. Such $39.0 million tax benefit was comprised primarily of a current income tax receivable of $151.4 million, partially offset by non-cash deferred tax expense of $112.4 million related to NOL utilization. As of December 31, 2020, we had received $134.0 million of the income tax receivable related to the CARES Act, along with an additional receipt of $4.4 million of related interest.
We include, as a component of our “Income tax provision,benefit (provision),” potential interest and penalties related to recognized tax contingencies within our global operations. Interest and penalties resulted in an income tax expensebenefit of $4.7$24.1 million in 2017,2020, an income tax benefit of $3.0 million in 2019 and an income tax expense of $2.7$5.1 million in 20162018.

During the year ended December 31, 2017,2020, our income tax provision included a non-cash, discrete itemthe following non-recurring significant items:
Tax benefit related to the following:
gross benefit of $260.7 million as the result of an internal tax restructuring, which was implemented to reduce costs associated with the ownership of multiple legal entities, simplify the overall legal entity structure, ease deployment of cash throughout the business and consolidate operations into one centralized group of entities.
As of December 31, 2017, we recorded deferred charges of $145.3$192.4 million related to the deferralimpairment of rigs and certain capital spares partially offset by a corresponding increase in valuation allowance of $92.7 million;
the application of the CARES Act of $39.0 million;
release of reserves related to the closure of the 2012-2017 US tax audit of $111.9 million; and
tax impact of an internal restructuring net of resulting adjustment of the valuation allowance of $17.9 million.
Tax expenses related to the following:
a 2019 US return-to-provision adjustment and resulting adjustment to the valuation allowance of $21.2 million;
an increase in UK valuation allowance of $31.1 million; and
an increase in non-US reserve of $7.8 million.
Our gross deferred tax asset balance at year-end reflects the application of our income tax expenseaccounting policies and is based on intercompany asset transfers asmanagement’s estimates, judgments and assumptions regarding realizability. If it is more likely than not that a result of our internal tax restructuring. The deferred charges are included in “Other assets” on the accompanying Consolidated Balance Sheet and are amortized as a component of income tax expense over the remaining lifeportion of the underlying assets.deferred tax assets will not be realized in a future period, the deferred tax assets will be reduced by a valuation allowance based on management’s estimates. During the year ended December 31, 2020, we recorded additional valuation allowance of $183.8 million for deferred tax assets in the US, Guyana and the UK.

Defined Benefit Plans
Noble Drilling (Land Support) Limited, an indirect, wholly-owned subsidiary of Noble (“NDLS”), maintains twoa pension plans for certainplan that covers all of ourits salaried, non-union employees, whose most recent date of employment is prior to April 1, 2014 operating in the North Sea, the Noble Drilling (Land Support) Limited (“NDLS”) and the Noble Resources Limited (“NRL”), both indirect, wholly-owned subsidiaries of Noble-UK. Reference(referred to as our “non-U.S. plans” included throughout this report relates to both the NDLS and NRL plans, as well as the activity for the two legacy plans for the periods prior to the Spin-off.“non-US plan”).
In addition to the non-U.S. plansnon-US plan discussed above, we have two U.S.a US noncontributory defined benefit pension plans: one whichplan that covers certain salaried employees and one whicha US noncontributory defined benefit pension plan that covers certain hourly employees, whose initial date of employment is prior to August 1, 2004 (collectively referred to as our “qualified U.S.US plans”). These plans are governed by the Noble Drilling Employees’ Retirement Trust (the “Trust”). The benefits from these plans are based primarily on years of service and, for the salaried plan, employees' compensation near retirement. These plans are designed to qualify under the Employee Retirement Income Security Act of 1974 (“ERISA”), and our funding policy is consistent with funding requirements of ERISA and other applicable laws and regulations. We make cash contributions, or utilize credit balancescredits available to us, under the plan, for the qualified U.S.US plans when required. The benefit amount that can be covered by the qualified U.S.US plans is limited under ERISA and the Internal Revenue Code (“IRC”) of 1986. Therefore, we maintain an unfunded, nonqualified excess benefit plan designed to maintain benefits for specified employees at the formula level in the qualified salary U.S.salaried US plan. We refer to the qualified U.S.US plans and the excess benefit plan collectively as the “U.S.“US plans.”
During the fourth quarter of 2016, we approved amendments, effective as of December 31, 2016, to our non-U.S.non-US and U.S.US defined benefit plans. With these amendments, employees and alternate payees will accrue no future benefits under the plans after December 31, 2016. However, these amendments will not affect any benefits earned through that date.
During the years ended December 31, 2017, we made contributions to our pension plans of approximately $0.6 million, which satisfied our obligations under our defined benefit plan for the North Sea region.

During the years ended December 31, 2017, 20162020, 2019 and 2015,2018, we adopted the Retirement Plan (“RP”) mortality tables with the Mortality Projection (“MP”) scale as issued by the Society of Actuaries for each of the respective years. The RP 2017, 20162020, 2019 and 20152018 mortality tables represent the new standard for defined benefit mortality assumptions due to adjusted life expectancies. The adoption of the updated mortality tables and the mortality improvement scales decreased our pension liability on our U.S.US plans by approximately $1.6$1.7 million, $2.9$2.1 million and $3.0$0.6 million as of December 31, 2017, 20162020, 2019 and 2015.2018.
During the fourth quarter of 2018, the UK High Court made a judgement confirming that UK pension schemes are required to equalize male and female members’ benefits for the effect of guaranteed minimum pensions (GMP). We have accounted for the impact of the GMP equalization as a plan amendment to our non-US plan, and the impact is included as a prior service cost as of December 31, 2020, which will be amortized over the average life expectancy of the members at that date.

cash outflows on our planplans reasonably match this index. For non-U.S. plans,our non-US plan, the discount ratesrate used to calculate the net present value of future benefit obligations areis determined by using a yield curve of high quality bond portfolios with an average maturity approximating that of the liabilities.
In developing the expected long-term rate of return on assets, we considered the current level of expected returns on risk free investments (primarily government bonds), the historical level of risk premium associated with the other asset classes in which the portfolio is invested and the expectations for future returns of each asset class. The expected return for each asset class was then weighted based on the target asset allocation to develop the expected long-term rate of return on assets for the portfolio. To assist us with this analysis, we employ third-party consultants for our U.S.US and non U.S.non-US plans that use a portfolio return model.

U.S.US Plans
The Trust investsfundamental objective of the US plan is to provide the capital assets necessary to meet the financial obligations made to plan participants. In order to meet this objective, the Investment Policy Statement depicts how the investment assets of the plan are to be managed in accordance with the overall target asset allocation of approximately41.0% equity securities, 57.7% fixed income debt securities, and cash equivalents and other short-term investments. The Trust may invest in these investments directly or through pooled vehicles, including mutual funds.
The Company’s overall investment strategy, or target range, is to achieve a mix of approximately 31.5 percent in equity securities, 67.3 percent in debt securities and 1.2 percent1.3% in cash holdings.and equivalents. The target asset allocation is intended to generate sufficient capital to meet plan obligations and provide a portfolio rate of return equal to or greater than the return realized using appropriate blended, market benchmark over a full market cycle (usually a five to seven year time period). Actual resultsallocations may deviate from the target range, however any deviation from the target range of asset allocations must be approved by the Trust’s governing committee.
The performance objective of the Trust is to outperform the return of the Total Index Composite as constructed to reflect the target allocation weightings for each asset class. This objective should be met over a market cycle, which is defined as a period not less than three years or more than five years. U.S. equity securities (common stock, convertible preferred stock and convertible bonds) should achieve a total return (after fees) that exceeds the total return of an appropriate market index over a full market cycle of three to five years. Non-U.S. equity securities (common stock, convertible preferred stock and convertible bonds), either from developed or emerging markets, should achieve a total return (after fees) that exceeds the total return of an appropriate market index over a full market cycle of three to five years. Fixed income debt securities should achieve a total return (after fees) that exceeds the total return of an appropriate market index over a full market cycle of three to five years.

Other Benefit Plans
We sponsor a 401(k) Restoration Plan, which is a nonqualified, unfunded employee benefit plan under which specified employees may elect to defer compensation in excess of amounts deferrable under our 401(k) savings plan. The 401(k) Restoration Plan has no assets, and amounts withheld for the 401(k) Restoration Plan are kept by us for general corporate purposes. The investments selected by employees and associated returns are tracked on a phantom basis. Accordingly, we have a liability to the employee for amounts originally withheld plus phantom investment income or less phantom investment losses. We are at risk for phantom investment income and, conversely, benefit should phantom investment losses occur. At both December 31, 20172020 and 2016,2019, our liability for the 401(k) Restoration Plan was $8.8$7.8 million and $7.7$8.4 million, respectively, and is included in “Accrued payroll and related costs.”
In 2005, we enacted a profit sharing plan, the Noble Drilling Services Inc. Profit Sharing Plan, which covers eligible employees, as defined.defined in the plan. Participants in the plan become fully vested in the plan after three-yearsthree years of service. We sponsor other retirement, health and welfare plans and a 401(k) savings plan for the benefit of our employees. On January 1, 2019, the 401(k) savings plan and the profit sharing plan were merged into the Noble Drilling Services Inc. 401(k) and Profit Sharing Plan.
Profit sharing contributions are discretionary, require Board of Directors approval and are made in the form of cash. Contributions recorded related to this plan totaled $3.1$2.4 million, $6.0$2.4 million and $6.5$2.3 million, respectively, for three years ended December 31, 2017, 20162020, 2019

Note 12—14— Derivative Instruments and Hedging Activities
We are exposed to certain concentrations of interest rate and foreign currency exchange rate risk: periodically, we enter into derivative instruments to manage our exposure to fluctuations in interest rates and foreign currency exchangethese rates. We have documented policies and procedures to monitor and control the use of derivative instruments. We do not engage in derivative transactions for speculative or trading purposes, nor are we a party to leveraged derivatives.
For foreign currency forward contracts, hedge effectiveness is evaluated at inception based on the matching of critical terms between derivative contracts and the hedged item. Any change in fair value resulting from ineffectiveness is recognized immediately in earnings.
On May 10, 2016, Freeport-McMoRan Inc. (“Freeport”), Freeport-McMoRan Oil & Gas LLC and one of our subsidiaries entered into an agreement terminating the contracts on the Noble Sam Croft and Noble Tom Madden (“FCX Settlement”), which were scheduled to end in July 2017 and November 2017, respectively. The FCX Settlement included two contingent payments, which are further discussed below. We accounted for these contingent payments as derivative instruments that did not qualify under the FASB standards for hedge accounting treatment, and therefore, changes in fair values were recognized as a loss in our accompanying Consolidated Statements of Operations.
Cash Flow Hedges
Several of our regional shorebases including our North Sea operations, have a significant amount of their cash operating expenses payable in local currencies. To limit the potential risk of currency fluctuations, we periodically enter into forward contracts, which settlehave historically settled monthly in the operations’ respective local currencies. All of these contracts havehad a maturity of less than 12 months. During 2017 and 2016,2020, we did 0t enter into any forward contracts. During 2019, we entered into forward contracts of approximately $37.6$15.8 million, and $53.1 million, respectively, all of which settled during their respective years.2019.

FCX Settlement
Pursuant to the FCX Settlement, Noble could have received contingent payments from the FCX Settlement on September 30, 2017, depending on the average price of oil over a 12-month period from June 30, 2016 through June 30, 2017. The average price of oil was calculated using the daily closing price of West Texas Intermediate crude oil (“WTI”) (CL1) on the New York Mercantile Exchange for the period of June 30, 2016 through June 30, 2017. If the price of WTI averaged more than $50 per barrel during such period, Freeport would have paid $25.0 million to Noble. In addition to the $25.0 million contingent payment, if the price of WTI averaged more than $65 per barrel during such period, Freeport would have paid an additional $50.0 million to Noble. These contingent payments did not qualify for hedge accounting treatment under FASB standards, and therefore, the change in fair value was recognized as a loss in our Consolidated Statements of Operations. These contingent payments are referred to as non-designated derivatives in the following tables.
The price of WTI did not average more than $50 per barrel during the 12-month period. As of June 30, 2017, the fair value of these contingent payments was reduced to zero, as the period for earning the contingent payments had ended.

Transocean Ltd.
In January 2017, a subsidiary of Transocean Ltd. (“Transocean”) filed suit against us and certain of our subsidiaries seeking damages for patent infringement in a Texas federal court. The suit claimsclaimed that five5 of our newbuild rigs that operated in the U.S.US Gulf of Mexico violated Transocean patents relating to what is generally referred to as dual-activity drilling. We were awaredrilling, and Transocean sought royalties of a $10.0 million fee and a 5 percent license fee for the patents whenpertinent period of operation for each vessel and damages for the breach of contract alleged in February 2019, regarding a 2007 settlement agreement that we constructed the rigs, and we do not believe that our rigs infringe theentered into with Transocean patents, which are now expired. The lawsuit is proceeding and we intendrelating to defend ourselves vigorously against this claim.
Department of Justice settlement.
In December 2014, one of our subsidiaries reached a settlement with the U.S. Department of Justice (“DOJ”) regarding our former drillship, the Noble Discoverer, and the Kulluk, a rig we were providing contract labor services for,patent claims in respect of violationsanother Noble rig. On September 15, 2020, the Company entered into a settlement agreement with Transocean to settle this matter in exchange for payment by the Company of applicable law discoveredan immaterial amount to be paid in connection with a 2012 Coast Guard inspection3 installment payments due 2020, 2021 and 2022, which was approved by the Bankruptcy Court on October 9, 2020 and is included in Alaska and“Liabilities subject to compromise” on our own subsequent internal investigation. Under the terms of the agreement, the subsidiary pled guilty to oil record book, ballast record and required hazardous condition reporting violations with respect to the Noble Discoverer and an oil record book violation with respect to the Kulluk. The subsidiary paid $8.2 million in fines and $4.0 million in community service payments and was placed on probation for four years, with the right to petition the court for early dismissal of probation after three years. We were granted our motion to early terminate the plea agreement effectiveConsolidated Balance Sheet as of March 1, 2018. If, during the remaining term of probation, the subsidiary fails to adhere to the terms of the plea agreement, the DOJ may withdraw from the plea agreement and would be free to prosecute the subsidiary on all charges arising out of its investigation, including any charges dismissed pursuant to the terms of the plea agreement, as well as potentially other charges. We also implemented a comprehensive environmental compliance plan in connection with the settlement.
Brazil commercial agent.
We have used a commercial agent in Brazil in connection with our Petróleo Brasileiro S.A. (“Petrobras”) drilling contracts. We understand that this agent has represented a number of different companies in Brazil over many years, including several offshore drilling contractors. In November 2015, this agent pled guilty in Brazil in connection with the award of a drilling contract to a competitor and implicated a Petrobras official as part of a wider investigation of Petrobras’ business practices. Following news reports relating to the agent’s involvement in the Brazil investigation in connection with his activities with other companies, we conducted a review, which is now substantially complete, of our relationship with the agent and with Petrobras. We have been in contact with the SEC, the Brazilian federal prosecutor’s office and the DOJ about this matter. We have cooperated with these agencies and they are aware of our internal review. To our knowledge, neither the agent, nor the government authorities investigating the matter, has alleged that the agent or Noble acted improperly in connection with our contracts with Petrobras.December 31, 2020.
Paragon Offshore.Offshore
On August 1, 2014, Noble-UKLegacy Noble completed the Spin-offseparation and spin-off of a majority of its standard specification offshore drilling business (the “Spin-off”) through a pro rata distribution of all of the ordinary shares of its wholly-owned subsidiary, Paragon Offshore plc (“Paragon Offshore”), to the holders of Legacy Noble’s ordinary shares. In February 2016, Paragon Offshore sought approval of a pre-negotiated plan of reorganization (the Prior Plan) by filingfiled for voluntary reliefprotection under Chapterchapter 11 of the United States Bankruptcy Code. As part of the Prior Plan, we entered into a settlement agreementCode in February 2016, and in connection with Paragon Offshore (the “Settlement Agreement”). The Prior Plan was rejected by the bankruptcy court in October 2016.
In April 2017, Paragon Offshore filed an updated disclosure statement and a revised plan of reorganization (the “New Plan”) in its bankruptcy proceeding. Under the New Plan, including Paragon Offshore’s revised business plan, Paragon Offshore no longer needed the Mexican tax bonding that Noble-UK was to provide under the Settlement Agreement. As a result, the Settlement Agreement was no longer applicable to the ongoing business of Paragon Offshore. Consequently, Paragon Offshore abandoned the Settlement Agreement as part of the New Plan, and the Settlement Agreement was terminated at the time of the filing of the New Plan. On May 2, 2017, Paragon Offshore announced that it had reached an agreement in principle with both its secured and unsecured creditors to revise the New Plan to, among other things, create and fund a $10.0 million litigation trust to pursue litigation against us. On June 7, 2017, the revised New Plan was approved by the bankruptcy court and Paragon Offshore emergedOffshore’s emergence from bankruptcy onin July 18, 2017.2017, all claims it may have had against Legacy Noble were transferred to a litigation trust.
On December 15, 2017, the litigation trust filed fraudulent conveyance and related claims relating to the Spin-off in an action (the “Action”) against usLegacy Noble and certain of ourits subsidiaries (the “Noble Defendants”) and certain of Legacy Noble’s then current and former officers and directors (the “Individual Defendants”) in the Delaware bankruptcy court that heard Paragon Offshore’s bankruptcy.bankruptcy (the “Delaware Court”). The complaint allegeslitigation trust sought total damages of approximately $2.6 billion and unspecified amounts in respect of the claims of alleged actual and constructive fraudulent conveyance, unjust enrichment and recharacterization of intercompany notes as equity claims against Noble and claims of breach of fiduciary duty and aiding and abetting breach of fiduciary duty against the officer and director defendants. We continuedefendants, all of whom had indemnification agreements with Legacy Noble.
On September 23, 2020, the Noble Defendants entered into a settlement agreement (the “Settlement Agreement”) with the litigation trust to believe that Paragon Offshore, atfully and finally settle the time ofdisputes among them in the Spin-off, was properly funded, solventAction on the terms set forth in the Settlement Agreement and, had appropriate liquiditysubject to certain terms and conditions, to allow the litigation trust’s claims to proceed against the Individual Defendants in the Delaware Court. Among other things, the Settlement Agreement provided that the claims broughtasserted by the litigation trust are without meritagainst each of the Noble Defendants in the Action would be allowed as a prepetition unsecured claim in the Chapter 11 Cases in the aggregate amount of $85 million, and, willon account of that claim, required the Debtors to either (a) make a $10 million payment to the litigation trust, if a full settlement and release of (i) all claims brought against all defendants in the Action, including the Noble Defendants and the Individual Defendants, (ii) the Noble Defense Cost Claim (as defined in the Settlement Agreement), and (iii) the Noble Indemnity Claim (as defined in the Settlement Agreement) (a “Global Resolution”) is reached on or before October 1, 2020, or (b) if a Global Resolution was not reached on or before October 1, 2020, make an up-front payment of $7.5 million for a release of only the claims against the Noble Defendants, and bring litigation against the insurers with respect to the Individual Defendants’ director and officer’s liability insurance policies the proceeds of which would be contested vigorouslyshared with the litigation trust on the terms and conditions set forth in the Settlement Agreement and with respect to a determination of the insurance coverage for the Noble Defendants.

The Global Resolution Agreement was subject to settle anyapproval by the Delaware Court, which approval was granted on February 24, 2021. All claims any damages or other amounts we would be required to or agree to pay could have a material adverse effect on our business, financial condition and results of operations. The litigation is in the very early stages, no schedule has been established, and we are not able to predict when, or if, the matters will go to trial or otherwise be concluded. We may be required to establish reserves on our financial statements in advance of the conclusion of the litigation. Such reserves may be substantial and could have a material adverse effect on our financial condition as presented in such financial statements.
Priorrelated to the completion of the Spin-off, Noble-UK and Paragon Offshore entered into the Separation Agreements to effect the separation and Spin-off and govern the relationship between the parties after the Spin-off, including the MSA and the TSA.
As part of its final bankruptcy plan, Paragon Offshore rejected the Separation Agreements. Accordingly, the indemnity obligations that Paragon Offshore potentially would have owed us under the Separation AgreementsAction have now terminated, including indemnities arising under the MSA and the TSA in respect of obligations related to Paragon Offshore’s business that were incurred through Noble-retained entities prior to the Spin-off. Likewise, any potential indemnity obligations that we would have owed Paragon Offshore under the Separation Agreements, including those under the MSA and the TSA in respect of Noble-UK’s business that was conducted prior to the Spin-off through Paragon Offshore-retained entities, are now also extinguished. In the absence of the Separation Agreements, liabilities relating to the respective parties will be borne by the owner of the legal entity or asset at issue and neither party will look to an allocation based on the historic relationship of an entity or asset to one of the party’s business, as had been the case under the Separation Agreements.fully settled.
Tax matters
The rejection and ultimate termination of the indemnity and related obligations under the Separation AgreementsInternal Revenue Service (“IRS”) has resulted in a number of accounting charges and benefits for the year ended December 31, 2017, and such termination may continue to affect us in the future as liabilities arise for which we would have been indemnified by Paragon Offshore or would have had to indemnify Paragon Offshore. We do not expect that, overall, the rejection of the Separation Agreements by Paragon Offshore will have a material adverse effect on our financial condition or liquidity. However, any loss we experience with respect to which we would have been able to secure indemnification from Paragon Offshore under one or more of the Separation Agreements could have an adverse impact on our results of operations in any period, which impact may be material depending on our results of operations during this down-cycle.
During the year ended December 31, 2017, we recognized net charges of $15.9 million, with a non-cash loss of $1.5 million in “Net loss from discontinued operations, net of tax” on our Consolidated Statements of Operations related to Paragon Offshore's emergence from bankruptcy.
Tax matters.
During 2014, the IRS begancompleted its examination of our tax reporting in the U.S.procedures, including all appeals and administrative reviews, for the taxable years ended December 31, 2010 and 2011. The2012 through December 31, 2017. In May 2020, the IRS examination team has completed its examination of our 2010 and 2011 U.S. tax returns and proposednotified us that it was no longer proposing any adjustments and deficiencies with respect to certain items that were reported by usour tax reporting for the 2010taxable years ended December 31, 2012 through December 31, 2017. Subsequent to our filing of an Application for Tentative Refund with the IRS under the CARES Act in the months of April and 2011August 2020, the IRS informed us that it would be conducting a limited scope examination of the taxable years ended December 31, 2012, 2013, 2014, 2018 and 2019. In the first quarter of 2020, we filed a foreign tax year. On December 19, 2016, we received the Revenue Agent Report (“RAR”) from the IRS.credit refund claim for taxable year 2009. The IRS is currently auditing taxable year 2009 in relation to our refund claim. We believe that we have accurately reported all amounts in our returns.
Audit claims of approximately $96.1 million attributable to income and other business taxes were assessed against Noble entities in Mexico related to tax returns,years 2007, 2009 and have submitted administrative protests with the IRS Office of Appeals contesting the examination team’s proposed adjustments.2010, in Australia related to tax years 2013 to 2016, in Guyana related to tax years 2019 and 2020 and in Saudi Arabia related to tax years 2015 to 2018. We intend to vigorously defend our reported positions and believe the ultimate resolution of the adjustments proposed by the IRS examination teamaudit claims will not have a material adverse effect on our consolidated financial statements. During the third quarter of 2017, the IRS initiated its examination of our 2012, 2013, 2014 and 2015 tax returns.
In previous periods, we reported that Mexican and Brazilian authorities had made significant tax assessments against Paragon Offshore entities, a portion of which related to Noble’s business that operated through Paragon Offshore-retained entities in Mexico and Brazil prior to the spin-off. As a result of the termination of the Separation Agreements, we no longer have any indemnity obligations in respect of these tax claims made against Paragon Offshore entities, and responsibility for these claims has reverted back to the applicable Paragon Offshore entity. Audit claims of approximately $48.3 million attributable to income and other business taxes have been assessed against Noble entities in Mexico.
In previous periods, we also reported that Petrobras had notified us that it was challenging assessments by Brazilian tax authorities of withholding taxes associated with the provision of drilling rigs for its operations in Brazil during 2008 and 2009. Petrobras had also notified us that if Petrobras was ultimately forced to pay such withholding taxes, it would seek reimbursement from Paragon Offshore who would then seek reimbursement from us for the portion of the withholding that was allocable to our drilling rigs. As a result of the termination of the Separation Agreements, we no longer have any indemnity obligation in respect of these withholding claims made against a Paragon Offshore entity, and responsibility for these claims has reverted back to the applicable Paragon Offshore entity.
We operate in a number of countries throughout the world and our tax returns filed in those jurisdictions are subject to review and examination by tax authorities within those jurisdictions. We recognize uncertain tax positions that we believe have a greater than 50 percent likelihood of being sustained.sustained upon challenge by a tax authority. We cannot predict or provide assurance as to the ultimate outcome of any existing or future assessments.

Note 19— Subsequent Events
2015 Credit Facility Amendment Effectiveness
On January 3, 2018, the Amendment to the 2015 Credit Facility became fully effective. The Amendment caused, among other things a reduction in the aggregate principal amount of commitments under the 2015 Credit Facility to $300.0 million and the reduction of the 2015 Credit Facility's letter of credit sub-facility to zero dollars. The maturity of the 2015 Credit Facility remains January 2020.
2017 Credit Facility Amendment Effectiveness

Changes in Internal Control Over Financial Reporting
There were no changes in either Noble-UK’s or Noble-Cayman’sNoble’s internal control over financial reporting that occurred during the yearquarter ended December 31, 20172020 that have materially affected, or are reasonably likely to materially affect, the internal control over financial reporting of each of Noble-UK or Noble-Cayman.Noble.
Management’s Annual Report on Internal Control Over Financial Reporting
The management of Noble-UK and Noble-CaymanNoble is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rule 13a-15(f) promulgated under the U.S.US Securities Exchange Act of 1934, as amended.
Internal control over financial reporting includes the controls themselves, monitoring (including internal auditing practices), and actions taken to correct deficiencies as identified. There are inherent limitations to the effectiveness of internal control over financial reporting, however well designed, including the possibility of human error and the possible circumvention or overriding of controls. The design of an internal control system is also based in part upon assumptions and judgments made by management about the likelihood of future events, and there can be no assurance that an internal control will be effective under all potential future conditions. As a result, even an effective system of internal controls can provide no more than reasonable assurance with respect to the fair presentation of financial statements and the processes under which they were prepared.
Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013. Based on the assessment by management of Noble-UK and Noble-Cayman, both Noble-UK and Noble-CaymanNoble, Noble maintained effective internal control over financial reporting as of December 31, 2017.2020.
PricewaterhouseCoopers LLP, the independent registered public accounting firm that audited our financial statements included in this Annual Report on Form 10-K, has audited the effectiveness of internal control over financial reporting as of December 31, 20172020 as stated in their report, which is provided in Part II, Item 8, “ Financial“Financial Statements and Supplementary Data” in this Annual Report on Form 10-K.
