To Our Shareholders

The  offshore  drilling  industry  continues  to  await 

robust  recovery.  However,  despite  the  various 
hurdles that the industry may face, at Noble, we 
still saw encouraging signs of improvement. 

There  is  little  doubt  that  weakness  in  crude  oil  and  natural  gas  prices  and  the 
recent  interruption  in  sustainable  trading  patterns  of  these  commodities  have  led 
to our customers demonstrating a disciplined approach to the business, including a 
commitment to spend within the limits of a restricted amount of annual cash flow and 
allocation of capital that has frequently subordinated offshore programs. 

However,  recent  activities  by  our  customers  imply  that  interest  in  offshore 
prospects is once again emerging. The resource potential found in many of the world’s 
offshore basins has continued to expand, while our customers’ cost per barrel of crude 
oil  equivalent  to  access  this  growing  potential  has  seldom  been  lower.  At  the  same 
time, our industry is experiencing important and much needed fundamental change, 
and we believe the lack of recent meaningful investment in offshore production will 
be  a  catalyst  in  an  improving  market  for  our  services.  Together,  these  important 
developments should set the stage for a robust business environment, and we certainly 
experienced encouraging signs of an improving market in 2018.

Indications of Growing Offshore Interest

Customer interest in emerging offshore basins is rapidly building due, in part, to 
improving  access  and  successful  exploration  results.  Guyana,  Brazil,  Suriname  and 
Mexico  offer  excellent  recent  examples  of  basins  where  exploration  and  production 
companies have gained access to expansive offshore acreage while the resource potential 
of these areas is increasingly supported by encouraging exploration results. In 2018, 
five of the 18 announced deepwater discoveries worldwide were located in these four 
basins. Offshore Guyana, where exceptional resource potential is particularly evident, 
12 out of 13 exploration probes to date have located hydrocarbons. It is worth noting 
that Noble is a leading provider of drilling services in this region with two of our ultra-
deepwater drillships located there. We expect exploration in these areas, and in others 
around the world, to experience gradual improvement as operators identify offshore 
prospects with excellent resource potential that can support future production growth 
and reserve replacement. 

Growing  interest  from  operators  is  not  limited  to  the  emerging  frontier  regions. 
Activity in mature offshore basins is also expected to expand due to a combination of 
changes in ownership of producing and undeveloped acreage, exploration success, and 
the presence of established offshore infrastructure that provides a quick and efficient 
path  to  commercialization.  The  North  Sea  has  been  a  prime  example  of  activity 
supported by new owners in mature basins. 

Finally, exploration and production companies are experiencing increased success 
in  utilizing  technological  advances  that  lower  the  cost  of  doing  business  offshore 
while delivering improved results in exploration and field recovery. Enhanced seismic 
acquisition  and  expedited  imaging  technologies  are  also  creating  value  for  our 
customers and should lead to increased offshore activity.

Improvement in Industry Fundamentals

In addition to the mounting evidence of growing offshore interest from operators, 
2018  saw  a  healthy  increase  in  bidding  and  award  activity,  including  a  welcomed 
improvement in the floating rig category. Jackup demand has continued to improve, 
particularly for high specification units which has led to improving margins for those 
assets.

Also,  the  industry’s  total  rig  supply  declined  further  in  2018  as  more  rigs  were 
retired from service. Among the industry’s floating rig fleet, 18 units were retired in 
2018,  bringing  the  total  number  of  floating  rig  retirements  since  2014  to  126  units, 
with additional retirements likely in the future. Noble has been an active participant 
in fleet rationalization, having retired approximately one-third of our fleet since late 
2014.  These  rig  retirements,  combined  with  the  addition  of  new,  high  specification 
assets,  have  resulted  in  one  of  the  industry’s  youngest,  most  modern  fleets.  Noble’s 
average fleet age is only six years as we begin 2019. 

Positioning Noble for Industry Recovery

We believe the early stages of recovery in the offshore drilling industry have begun. 
As  a  result  of  this  outlook,  we  have  taken  several  actions  in  2018  and  into  2019  to 
strengthen our customer base and further improve our ability to compete in what will 
remain a competitive industry environment. These actions were led by our acquisition 
of two newbuild jackups. The attractively priced rigs, the Noble Johnny Whitstine and 
Noble Joe Knight, have both received multi-year contracts for operations in the Middle 
East. These modern, fit-for-purpose drilling solutions are expected to remain active in 
the region well into the future.  

We believe 
a prolonged 
period of under-
investment by 
exploration 
and production 
companies over 
recent years 
will provide the 
eventual 
catalyst for 
increased offshore 
rig demand.  

Also,  in  keeping  with  our  improved  industry  outlook, 
we  completed  reactivation  programs  for  five  premium 
rigs,  including  four  ultra-deepwater  floating  units  and 
a  high-specification  jackup.  Recognizing  our  customers’ 
preference  for  premium  rigs  with  proven  performance 
records,  we  moved  decisively  to  position  each  unit  to 
compete for an expanding list of contract opportunities in 
2018 and beyond. Our intended objective was achieved, as 
all of the reactivation projects were executed successfully, 
with each of the five units securing contracts. Even better, 
new contract opportunities are now visible, increasing the 
likelihood that each of these rigs will remain contractually 
engaged well into or beyond 2019, as demonstrated by the 
recent contract award for the drillship Noble Tom Madden 
in Guyana.

I also believe efforts to focus our fleet in key geographies 
have advantageously positioned our premium jackup and 
floating rigs for a growing number of contract opportunities 
as customer demand strengthens. In our jackup fleet, 11 of 
our 13 units are, or will soon be, located in the North Sea 
and Middle East regions where numerous customer needs 
are  outstanding,  including  an  estimated  50  rig-years  of 
customer demand in the Middle East.

Our marketed premium floating fleet is concentrated in the Western Hemisphere 
where enormous resource potential is driving heightened ultra-deepwater exploration 
interest  and  multi-year  development  opportunities.  We  have  already  established 
ourselves  as  a  leading  service  provider  in  some  regions,  such  as  Guyana,  and  we 
have an established and successful history in others, such as the U.S. Gulf of Mexico, 
Suriname, Mexico and Brazil, attractive locations to which we maintain prompt access. 

In  2018,  for  the  second  consecutive  year,  we  established  record  results  in  fleet 
uptime  and  safety  performance  as  measured  by  our  total  recordable  incident  rate. 
More impressively, these important measures of operational execution were achieved 
during a year in which we increased our active fleet by four rigs and expanded our 
headcount  by  10  percent.  Safety  performance  and  operational  excellence  have  long 
been hallmarks at Noble and will continue to contribute to our success going forward. 

Conclusion

We believe a prolonged period of under-investment by exploration and production 
companies over recent years will provide the eventual catalyst for increased offshore 
rig demand. Recent actions by our customers are encouraging and should eventually 
support  heightened  offshore  activities.  As  we  enter  2019,  Noble  is  better  positioned 
to  capture  this  expected  growth  in  customer  activity,  and  we  remain  committed  to 
maintaining  our  foundation  and  culture  of  safe,  environmentally  respectful  and 
efficient service delivery through the cycle. 

Thank you for your continued interest in Noble. I extend my gratitude on behalf 
of our Board of Directors to the entire Noble team for their exemplary hard work and 
dedication to pursuing excellence at all times. I look forward to success in the New Year 
as we extend the achievements of 2018.

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.

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 19, 2019, our fleet of 24 drilling rigs consisted of eight drillships, 
four semisubmersibles and 12 jackups. On February 14, 2019, we exercised an option to purchase an additional jackup and expect to complete 
the purchase in late February 2019.

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. 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 certain matters relating to Paragon Offshore, see Part I, Item 1A, “Risk Factors” and Part II, Item 7, “Management’s 
Discussion and Analysis of Financial Condition and Results of Operations— Executive Overview— Spin-off of Paragon Offshore plc” and Part 
II, Item 8, “Financial Statements and Supplementary Data, Note 15— Commitments and Contingencies.”

Drilling Services

We typically provide contract drilling services under an individual 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 wells;
payment of compensation to us (generally in U.S. 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;
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.

During periods of depressed market conditions, such as the one we are currently experiencing, 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.

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 24 offshore drilling units, consisting of eight drillships, four semisubmersibles and 12 jackups, 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, 2018, our fleet was located in Canada, Far East Asia, the Middle East, the North Sea, Oceania, the Black 
Sea, South America and the U.S. Gulf of Mexico.

Drillships

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. There are currently eight drillships in Noble's fleet, capable of water 
depths from 8,200 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 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 four semisubmersible drilling units, two of which are equipped with mooring systems and two of which 
utilize DPS, with fleet diversity to operate in mid-water, deepwater and ultra-deepwater depth ranges with high levels of efficiency.

Jackups

Noble's fleet of modern, high-specification jackup drilling units give 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. 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 standard 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 with drilling hookloads greater than 2,500,000 pounds.

Market

The offshore contract drilling industry is a highly competitive and cyclical business characterized by large capital expenditures and large 
swings in pricing. Demand for offshore drilling equipment is driven by 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 availability and relative cost of onshore oil and gas resources, general 
global economic conditions, energy demand, 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 equipment well-maintained and technologically competitive.

We maintain a global operational presence and compete in most of the major offshore oil and gas basins worldwide. All of 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.

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. Our industry experienced a significant increase in the number of drilling units prior to and during the period in which crude oil 
prices declined precipitously and were highly volatile and in which the supply of onshore oil and gas resources expanded greatly. This combination 
of increased supply of drilling rigs and reduced demand for such rigs has resulted in falling dayrates and heightened competition for opportunities 
to re-contract our rigs upon expiry of existing contracts. 

We believe that improvements in market conditions will ultimately result from, among other things, improved oil prices, additional investment 
by our customers in offshore exploration and development, and attrition of rigs in the global offshore fleet. Our young and technologically advanced 
fleet is well positioned to compete now and in the future as market dynamics improve.

Significant Customers

Offshore contract drilling operations accounted for approximately 96 percent, 98 percent and 97 percent of our operating revenues for the 
years ended December 31, 2018, 2017 and 2016, respectively. During the three years ended December 31, 2018, 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 U.S. 
Gulf of Mexico. Revenues from Royal Dutch Shell plc (“Shell”), Equinor ASA (“Equinor” formerly known as “Statoil ASA”) and Saudi Arabian 
Oil Company (“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. Revenues from Shell, Equinor and Saudi Aramco accounted for approximately 45.0 
percent, 13.2 percent and 11.4 percent, respectively, of our consolidated operating revenues for the year ended December 31, 2017. Revenues 
from Shell and Freeport-McMoRan Inc. (“Freeport”) accounted for approximately 37.5 percent and 24.5 percent, respectively, of our consolidated 
operating revenues for the year ended December 31, 2016. No other customer accounted for more than 10 percent of our consolidated operating 
revenues in 2018, 2017 or 2016.

 On May 10, 2016, Freeport, Freeport-McMoRan Oil & Gas LLC and one of our subsidiaries entered into an agreement terminating the 
contracts on the Noble Sam Croft and the Noble Tom Madden (“FCX Settlement”), which were scheduled to end in July 2017 and November 2017, 
respectively. During 2016, we recognized approximately $393.0 million in “Contract drilling services revenue” associated with the FCX Settlement. 
Excluding the $393.0 million of revenue attributable to the FCX Settlement our primary customers during 2016 would have been Shell, Anadarko 
Petroleum  Corporation  and  Freeport,  accounting  for  approximately  45.0  percent,  11.0  percent  and  9.0  percent  of  our  consolidated  operation 
revenues, respectively.

Employees

At  December 31,  2018,  we  had  approximately  2,000  employees,  excluding  approximately  1,000  persons  we  engaged  through  labor 
contractors or agencies. Approximately 84 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 place considerable value on the involvement 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 Noble Advances, our state of the art training facility in Sugar Land, Texas.

7

We are committed to a policy of recruitment and promotion based upon merit without discrimination. Management actively pursues both 
the employment of disabled persons whenever a suitable vacancy arises and the continued employment and retraining of employees who become 
disabled while employed by the Company. Training and development is undertaken for all employees, including disabled persons.

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 and operation of drilling units, environmental discharges and related recordkeeping, safety 
management systems, the reduction of greenhouse gas emissions to address climate change, currency conversions and repatriation, oil and gas 
exploration and development, taxation of offshore earnings and earnings of expatriate personnel 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”), 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 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, results in reduced demand for our services or imposes 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 environmental 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 U.S. Department of Interior, through 
the Bureau of Ocean Energy Management (“BOEM”) and the Bureau of Safety and Environmental Enforcement (“BSEE”), has undertaken an 
aggressive overhaul of the offshore oil and natural gas regulatory process that has significantly impacted oil and gas development in the U.S. Gulf 
of Mexico. From time to time, new rules, regulations and requirements 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 Ports and Waterways Safety 
Act (“PWSA”) and similar regulations, which impose certain operational requirements on offshore rigs operating in the U.S. and governs liability 
for vessel or cargo loss, or damage to life, property, or the marine environment. See Part I, Item 1A, “Risk Factors —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” for additional information.

Spills and Releases. The U.S. Oil Pollution Act of 1990 (“OPA”), the Comprehensive Environmental Response, Compensation, and Liability 
Act in the U.S. (“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. 
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 regulation, 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.

8

Waste Handling. The U.S. 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. operations.

Water Discharges. The U.S. 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 Guard 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. We do not anticipate that compliance with these laws will cause a material 
impact on our operations or financial condition.

Air Emissions. The U.S. 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. 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”) 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 drillships. 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. 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. Incentives to conserve energy 
or use alternative energy sources could have a negative impact on our business if such incentives reduce the worldwide demand for oil and gas. 
See Part I, Item1A, “Risk Factors— 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 a 21 percent GHG reduction from these sectors 
between 2005 and 2020. The ETS program will continue to require GHG reductions in the future.  Phase 4 of the ETS program (covering 2021 
to 2030) was revised in 2018 to achieve emission reduction targets as part of the EU’s contribution to the Paris Agreement. Phase 4 targets a 43 
percent GHG reduction between 2005 and 2030.

In addition, the United Kingdom (“UK”) government, which implements ETS in the UK North Sea, has introduced a carbon price floor 
mechanism to place an incrementally increasing minimum price on carbon. Thus, the cost of compliance with 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 diesel fuel (Scope 1) aboard all of our vessels worldwide is the Company’s primary source of GHG 
emissions, including carbon dioxide, methane and nitrous oxide. The data necessary to report indirect emissions from generation of purchased 
power (Scope 2) has not been previously collected; however, procedures are being established to collect and report Scope 2 data.

For the year ended December 31, 2018, our estimated carbon dioxide equivalent (“CO2e”) gas emissions were 954,944 tonnes as compared 
to 918,439 tonnes for the year ended December 31, 2017. When expressed as an intensity measure of tonnes of CO2e gas emissions per dollar of 
contract drilling revenues from continuing operations, the intensity measure for December 31, 2018 and 2017 was .0009 and .0008, respectively. 

9

The increase in emissions is due to increases in operational activity from the Noble Tom Madden, Noble Sam Croft, Noble Lloyd Noble, Noble 
Tom Prosser and activation of the Noble Clyde Boudreaux.

Our Scope 1 CO2e 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).” 

It is our intent to have the procedures related to GHG emissions independently assessed in the future.

Worker Safety. The U.S. 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 maritime trade. 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 system that 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 MARPOL, including Annex VI to MARPOL which sets limits on sulfur dioxide and nitrogen oxide emissions 
from ship exhausts and prohibits deliberate emissions of ozone depleting substances. 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 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 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. 

10

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 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 $10.0 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.

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 and negatively impacted and our market value has substantially declined 
due to current depressed market conditions which are the result of the dramatic drop in the oil price, the development of additional onshore 
oil and gas resources and the oversupply of offshore drilling rigs.

After a period of sustained high crude oil prices, oil prices began a steep decline beginning in late 2014 and dropped to as low as approximately 
$30 per barrel in January 2016. Oil prices have recovered to a price of approximately $66 per barrel on February 19, 2019, but have been volatile 
and have never recovered to 2014 levels. As a result of the oil price environment prior to the 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 at 
the same time that our customers have greatly reduced their planned offshore exploration and development spending in response to the depressed 
price of oil. 

During the same period, crude oil production in the U.S. rose sharply. Production in the U.S. Permian Basin has increased from less than 
1.5 million barrels of oil per day to nearly 4 million barrels per day. While, the cost of production in the Permian Basin (and many other onshore 
fields) varies, in some cases it may be significantly less than the cost of production in offshore fields where our rigs are designed to operate, 
especially deepwater fields. This increase in U.S. 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 

11

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.

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 $3.15 at February 19, 2019. 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 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 which 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 production 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, 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;
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;
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, winter storms and rough seas;
tax laws, regulations and policies;
laws and regulations related to environmental matters, including those addressing alternative energy sources 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, 
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 

12

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 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 recourses than we do. 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. 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.

The over-supply of offshore rigs is contributing to a reduction in dayrates and demand for our rigs, which reduction may continue 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. 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 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 analysis for the years ended December 31, 2018 and 2017, we 
decided that we would no longer market certain rigs. In connection with these decisions, we recorded impairment charges of $802.1 million and 
$121.6 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.

13

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.

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 replacement 
contracts at all.  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 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. 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. 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, Equinor 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, Equinor and Saudi Aramco accounted for approximately 
38.8 percent, 15.5 percent and 14.5 percent, respectively, of our consolidated operating revenues and approximately 52.2 percent, 11.0 percent 
and 19.8 percent, respectively, of our backlog for the year ended December 31, 2018. 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.

A litigation trust was formed and funded as part of the Paragon Offshore bankruptcy proceedings and the litigation trust has filed claims 
against us and certain of our officers and directors. In addition, Paragon Offshore rejected in the bankruptcy proceedings certain separation 
agreements entered into with us, and as a result, we are 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, to the holders of our ordinary shares. 

14

In April 2017, Paragon Offshore filed a plan of reorganization (the “Plan”) in its bankruptcy proceeding. The Plan, which was modified 
in May 2017, provided for the creation of a litigation trust 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 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. The complaint states that the litigation 
trust is seeking damages of approximately $1.7 billion from the Company, an amount equal to the amount borrowed by Paragon Offshore immediately 
prior  to  the  Spin-off,  as  well  as  unspecified  amounts  in  respect  of  the  claims  against  the  officer  and  director  defendants,  all  of  whom  have 
indemnification agreements with us. We requested that the court dismiss the claims of breach of fiduciary duty, aiding and abetting breach of 
fiduciary duty and unjust enrichment, and require such claims to be arbitrated under the master separation agreement (the “MSA”) entered into 
between Noble and Paragon Offshore at the time of the Spin-off, as well as stay the other proceedings during the pendency of the arbitration. The 
court ruled that the unjust enrichment claim be arbitrated and that the other claims proceed in bankruptcy court. We and the litigation trust have 
mutually agreed to drop our respective appeals of the arbitration ruling and now all matters will be heard in court, which will streamline the case. 
Discovery continues and the court has approved a litigation schedule, which could result in all pre-trial activity being completed by the end of 
2019. A trial date has not yet been set.

We believe that Paragon Offshore, at the time of the Spin-off, was properly funded, solvent and had appropriate liquidity and that the claims 
brought by the litigation trust are without merit. We intend to defend ourselves vigorously. However, there is inherent risk and substantial expense 
in litigation, and the amount of damages the plaintiff is seeking is substantial. If any of the litigation trust’s claims are successful, or if we elect 
to settle any claims (in part to reduce or eliminate the ongoing cost of defending the litigation and eliminate any risk of a larger judgment against 
us), 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. Because of our view of the merits of the claims and the significant discovery still to be conducted in the litigation, we 
are not currently able to make a reasonable estimation of the amount of possible loss we may incur, if any. Subsequent developments in the litigation 
may make such an estimation possible, in which case we may record a charge against our income when a loss is reasonably estimable. This may 
occur even though the litigation may still be ongoing. Any charge could be material and could have a material adverse effect on our financial 
condition and results of operations. It may also be materially different than any amount we are required to pay once the litigation is concluded. 

We have directors’ and officers’ indemnification coverage for the officers and directors who have been sued by the litigation trust. The 
insurers have accepted coverage for the director and officer claims and we are continuing to discuss with them the scope of their reimbursement 
of litigation expenses. In addition, at the time of the Spin-off we had entity coverage, or “Side C” coverage, which was meant to cover certain 
litigation claims up to the coverage limit of $150.0 million, including litigation expenses. We have made a claim for coverage of the litigation 
trust’s claims against Noble under such entity insurance. The insurers have rejected coverage for these claims. We cannot predict the amount of 
claims and expenses we may incur, pay or settle in the Paragon Offshore litigation that such insurance will cover, if any.

We entered into certain separation agreements with Paragon Offshore at the time of the Spin-off (including the MSA, 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.

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;

15

 
• 
• 
• 

toxic gas emanating from the well;
spillage handling 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 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 have substantial debt obligations that have significant covenant restrictions and could restrict our operations and prevent us from 

fulfilling our obligations with respect to our outstanding debt.

As of February 19, 2019, Noble-Cayman and its subsidiaries, including NHIL and its subsidiaries, had approximately $3.9 billion aggregate 
principal amount of unsecured long-term senior notes and seller loans (including current maturities) outstanding. At February 19, 2019, no amounts 
were currently outstanding under our 2015 Credit Facility or our 2017 Credit Facility (each as defined herein). We may also incur additional 
indebtedness in the future. If we do so, the risks related to our level of debt could intensify. Our substantial indebtedness could have adverse 
consequences, including: 

• 

• 

• 

• 

making it more difficult for us to satisfy our financial obligations, including our obligations with respect to our outstanding 
debt; 
increasing our vulnerability to adverse economic, regulatory and industry conditions, and placing us at a disadvantage 
compared to our competitors that are less leveraged; 
limiting our ability to compete and our flexibility in planning for, or reacting to, changes in our business and the industry in 
which we operate; and 
limiting our ability to borrow additional funds for working capital, capital expenditures, acquisitions and general corporate or 
other purposes. 

Our debt service obligations will require us to use a significant portion of our operating cash flow to pay interest and principal on indebtedness 
instead of for other corporate purposes, including funding future expansion of our business and ongoing capital expenditures, which could impede 
our growth. If our operating cash flow and capital resources are insufficient to comply with the financial covenants in our Credit Facilities or to 
service our debt obligations, we may be forced to sell assets, seek additional equity or debt financing or restructure our debt, which could harm 
our long-term business prospects. Our failure to comply with those covenants could result in an event of default which, if not cured or waived, 
could result in the acceleration of all of our debt. Our 2017 Credit Facility contains a covenant which limits our debt to total tangible capitalization 
(less noncontrolling interest) to a maximum 0.55 ratio. If we increase our indebtedness, including by borrowing under the 2017 Credit Facility, 
or incur further losses without reducing our indebtedness or increasing capital by an equivalent amount, our debt to total tangible capitalization 
ratio would increase.

To service our indebtedness, we will use a significant amount of cash. Our ability to generate cash to service our indebtedness depends 

on many factors beyond our control.

Our ability to make payments on our indebtedness and to fund planned capital expenditures will depend on our ability to generate cash 

in the future. This ability, to a certain extent, is subject to general economic, financial, competitive, legislative, regulatory and other factors that 
are beyond our control. We cannot assure you that cash flow generated from our business and other sources of cash, including future 
borrowings by Noble-Cayman and Noble International Finance Company, a Cayman Islands company and a wholly-owned indirect subsidiary 
of Noble-Cayman (“NIFCO”), under our 2015 Credit Facility or by Noble Cayman Limited, a Cayman Islands company and a wholly-owned 
indirect subsidiary of Noble-Cayman, and NIFCO under our 2017 Credit Facility, will be sufficient to enable us to pay our indebtedness and to 
fund our other liquidity needs.

As a result of our significant cash flow needs, we may be required to raise funds through the issuance of additional debt or equity, 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 

16

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.

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 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;
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;
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.

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 United Kingdom (“U.K.”) held a referendum in which voters approved an exit from the European Union (“E.U.”), 
commonly referred to as “Brexit” and in March 2017 the U.K. formally started the process for the U.K. to leave the E.U. Given the lack of 
comparable precedent, it is unclear how disruptive the withdrawal will be, including possible financial, trade, regulatory and legal implications. 
Brexit creates 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. While our business is internationally diversified, the Company is incorporated and registered within the U.K. 
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.

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. 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 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. 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. 

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, 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 importing, exporting, equipping and operation of drilling rigs;
currency exchange controls;
oil and gas exploration and development;

18

• 
• 

taxation of offshore earnings and earnings of expatriate personnel; and
use and compensation of local employees and suppliers by foreign contractors.

Public and regulatory scrutiny of the energy industry has resulted in increased regulations being either proposed or 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 U.S., 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. BSEE 
also finalized a rule in September 2016 concerning production safety systems for oil and natural gas operations on the Outer Continental Shelf. 
However, in December 2017, BSEE published a proposed rule that would revise certain requirements from the September 2016 rule. The final 
rule implementing these revisions was published in September 2018. In addition, in May 2018, BSEE published a proposed rule that would revise 
several requirements of the blowout preventer systems and well control rule. A final rule has not yet been issued. 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. Implementation 
of the NTL is currently stayed pending further action by BOEM. However, 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 the United 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 new legislation 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.

We could also be affected by challenges to offshore operations by environmental groups and coastal states. 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 nine coastal states also sought to 
intervene as plaintiffs. 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.

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.

19

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;
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 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.

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 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 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 

20

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 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. Currently, we do not carry insurance for losses related to cybersecurity attacks, and may elect to 
not obtain such insurance in the future.

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 U.S. 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.

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. 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.

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;

21

• 

• 
• 

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 continue to reactivate rigs that have been cold or warm stacked and make selective purchases of rigs, such as the Noble Johnny 
Whitstine purchased in 2018 and the Noble Joe Knight, for which the purchase is expected to be completed in late February 2019. 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;

22

• 
• 
• 
• 
• 
• 
• 
• 
• 

• 

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.

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, as 
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. As 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.

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

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. 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, such as the Crimean region of the Ukraine, Cuba, Iran, North 
Korea, Sudan and Syria. The U.S. 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. Although 
we believe that we will be in compliance with all applicable sanctions and embargo laws and regulations at the filing date, and intend to maintain 
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 investors 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.

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.

24

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.

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.

Market for Shares and Related Shareholder Information

Noble-UK shares are listed and traded on the New York Stock Exchange under the symbol “NE.” 

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 law. 
Therefore, Noble-UK is not permitted to pay dividends out of share capital, which includes share premium. Noble has 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.

On February 19, 2019, there were 248,704,351 shares outstanding held by 167 shareholder accounts of record.

UK Tax Consequences to Shareholders of Noble-UK

The tax consequences discussed below do not reflect a complete analysis or listing of all the possible tax consequences that may be relevant 
to shareholders of Noble. Shareholders should consult their own tax advisors in respect of the tax consequences related to receipt, ownership, 
purchase or sale or other disposition of our shares. 

25

 
UK Income Tax on Dividends and Similar Distributions

A non-UK tax resident holder will not be subject to UK income taxes on dividend income and similar distributions in respect of our 
shares, unless the shares are attributable to a permanent establishment or a fixed place of business maintained in the UK by such non-UK holder.

Disposition of Noble—UK Shares

Shareholders who are neither UK tax residents nor holding their Noble-UK shares in connection with a trade carried on through a permanent 
establishment in the UK will not be subject to any UK taxes on chargeable gains as a result of any disposals of their shares. Noble-UK shares held 
outside the facilities of The Depository Trust Company (“DTC”) should be treated as UK situs assets for the purpose of UK inheritance tax.

UK Withholding Tax—Dividends to Shareholders

Payments of dividends by Noble-UK will not be subject to any withholding in respect of UK taxation, regardless of the tax residence of 

the recipient shareholder.

Stamp Duty and Stamp Duty Reserve Tax in Relation to the Transfer of Shares

Stamp duty and/or stamp duty reserve tax (“SDRT”) are imposed by the UK on certain transfers of chargeable securities (which include 
shares in companies incorporated in the UK) at a rate of 0.5 percent of the consideration paid for the transfers in question. Certain transfers of 
shares to depositaries or into clearance systems are charged at a higher rate of 1.5 percent. Her Majesty’s Revenue and Customs (“HMRC”) regard 
DTC as a clearance system for these purposes.

Transfers of the ordinary shares through the facilities of DTC will not attract a charge to stamp duty or SDRT in the UK. Any transfer of 
title to ordinary shares from within those facilities to a holder outside those facilities, and any subsequent transfers that occur entirely outside those 
facilities, will ordinarily attract stamp duty or SDRT at a rate of 0.5 percent. This duty must be paid (and, where relevant, the transfer document 
stamped by HMRC) before the transfer can be registered in the books of Noble-UK. However, if those ordinary shares of Noble-UK are redeposited 
into the facilities of DTC, that redeposit will attract stamp duty or SDRT at the rate of 1.5 percent.

Share Repurchases

Under UK law, the Company is only permitted to purchase its own shares by way of an “off-market purchase” in a plan approved by 
shareholders. We currently do not have shareholder authority to repurchase shares. During the years ended December 31, 2018, 2017 and 2016, 
we did not repurchase any of our shares.

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 24 drilling rigs consisted of eight drillships, four semisubmersibles and 12 jackups 
strategically deployed worldwide in both established and emerging ultra-deepwater and shallow water locations. 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 2018 financial and operating results from continuing operations include:

• 

• 

• 

operating revenues totaling $1.1 billion;

net loss of $885.1 million, or 3.59 per diluted share, which includes a $802.1 million before-tax impairment charge recognized 
on five of our rigs and certain capital spare equipment; and

net cash from operating activities totaling $171.9 million.

Our business strategy focuses on a balanced, high-specification fleet of both floating and jackup rigs and the deployment of our drilling 

rigs in established and emerging offshore oil and gas basins around the world.

Our floating and jackup drilling fleet is among the youngest, most modern and versatile in the industry. Our fleet consists predominately 
of  technologically  advanced  units,  equipped  with  sophisticated  systems  and  components  capable  of  executing  our  customers'  increasingly 
complicated offshore drilling programs safely and with greater efficiency. A total of 15 of our drilling rigs have been delivered since 2011 following 
their construction in quality shipyards located primarily in Korea and Singapore. The last of our new rig additions was delivered in July 2016, and 
no further newbuild rig construction is in process. We have also retired or sold 11 drilling rigs since late 2014, due in part to advanced service 
lives, high cost of operation and limited customer appeal. Current market conditions could lead to us stacking or retiring additional rigs.

On September 21, 2018, we purchased the Noble Johnny Whitstine, a new GustoMSC CJ46 design jackup rig, from the PaxOcean Group 
(“PaxOcean”) in connection with a concurrently awarded drilling contract in the Middle East region. We paid $93.8 million for the rig, with $33.8 
million paid in cash and the remaining $60.0 million of the purchase price financed by the seller. On February 14, 2019, we exercised our option 
to purchase a second newbuild CJ46 jackup from PaxOcean, to be known as the Noble Joe Knight, and we expect to complete the purchase in late 
February 2019. The purchase of the Noble Joe Knight will be funded with cash and seller financing on terms similar to the Noble Johnny Whitstine. 
See “Part II, Item 8, “Financial Statements and Supplementary Data, Note 7— Debt” for additional information.

Market Outlook

During 2018, higher average crude oil prices led to a slight improvement in customer activity, most notably across the jackup fleet. However, 
the challenging business environment for offshore drillers continued to persist due to an industry-wide rig supply imbalance that resulted from a 
multi-year period of investment in new offshore drilling capacity and the sustained drop in oil prices. Following the period of industry expansion, 
a period of oil price volatility compelled exploration and production companies to deemphasize offshore programs while focusing instead on land-
based opportunities, such as unconventional land opportunities. A portion of the newbuild capacity ordered prior to the decline in industry activity 
continues to exit shipyards, while the delivery of other newbuild rigs has been delayed into the future. In either case, these rigs have added to the 
prevailing 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, but the pace of 
attrition is significantly less than what would be required to remedy the capacity imbalance. Additionally, our customers have adopted a cautious 
approach to offshore spending due, in part, to volatility in crude oil prices over the past four years. We expect that the offshore drilling programs 
of operators will remain somewhat curtailed, as our customers continue to favor cash flow realization over long cycle investment in offshore 
production and exploration. During 2018, we recognized improvement in leading edge dayrates in the high specification jackup sector, especially 
in regions such as the North Sea and Middle East where approximately 80 percent of our fleet is located. We remain cautiously optimistic that 
this trend will continue into 2019. However, the floating sector did not enjoy the same pricing improvement as the jackup sector and additional 
customer activity will be required before dayrates move higher. 

In spite of the gradual improvement in offshore activities in 2018, we expect the business environment for 2019 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 oil demand growth, the lack of production investments in various countries around the 
world and the production limits agreed to by OPEC and other significant oil producing countries should support higher sustained crude prices, 
and lead to improved offshore spending by our customers over time. 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.

29

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.

Due to numerous factors that influence our customers' annual global offshore spending patterns, including geopolitical events, 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 
the existence of certain factors should over time contribute to an improvement in the market for our services, driven in part by an acceleration in 
customers’ offshore spending. These factors include:

• 

• 

• 

• 

• 

• 

• 

sustained crude oil prices;

improved geologic success with regard to our customers’ exploration efforts;

greater customer access to areas with promising offshore resource potential;

advances in offshore technological applications which reduce offshore costs and improve project economics;

high rate of natural depletion relating to land-based sources of crude oil production;

deteriorating annual production and poor reserve replacement metrics caused, in part, by a period of sustained under-investment 
by our customers; and

declining supply of rigs due to continued attrition.

We believe that we are strategically well positioned during this period of fundamental weakness for several reasons, including 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. Although we plan to prioritize capital preservation and liquidity based on the challenging market conditions, from 
time to time we will also continue to evaluate opportunities to enhance our fleet of floating and jackup rigs, particularly focusing on higher 
specification rigs, to execute the increasingly complex drilling programs required by our customers.

Spin-off of Paragon Offshore plc 

  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 of the ordinary shares of its wholly-owned subsidiary, Paragon Offshore plc (“Paragon 
Offshore”), to the holders of Noble’s ordinary shares. In February 2016, Paragon Offshore sought approval of a pre-negotiated plan of reorganization 
(the “Prior Plan”) by filing for voluntary relief under Chapter 11 of the United States Bankruptcy Code. As part of the Prior Plan, we entered into 
a settlement agreement with Paragon Offshore (the “Settlement Agreement”). The Prior Plan was rejected by the bankruptcy court in October 
2016.

  In April 2017, Paragon Offshore filed a revised plan of reorganization (the “New Plan”) in its bankruptcy proceeding. Under the New 
Plan, Paragon Offshore no longer need the Mexican tax bonding that Noble-UK was to provide under the Settlement Agreement. 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 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. The complaint states that the litigation 
trust is seeking damages of approximately $1.7 billion from the Company, an amount equal to the amount borrowed by Paragon Offshore immediately 
prior  to  the  Spin-off,  as  well  as  unspecified  amounts  in  respect  of  the  claims  against  the  officer  and  director  defendants,  all  of  whom  have 
indemnification agreements with us. We requested that the court dismiss the claims of breach of fiduciary duty, aiding and abetting breach of 
fiduciary duty and unjust enrichment, and require such claims to be arbitrated under the master separation agreement (the “MSA”) entered into 
between Noble and Paragon Offshore at the time of the Spin-off, as well as stay the other proceedings during the pendency of the arbitration. The 
court ruled that the unjust enrichment claim be arbitrated and that the other claims proceed in bankruptcy court. We and the litigation trust have 
mutually agreed to drop our respective appeals of the arbitration ruling and now all matters will be heard in court, which will streamline the case. 
Discovery continues and the court has approved a litigation schedule, which could result in all pre-trial activity being completed by the end of 
2019. A trial date has not yet been set.

We believe that Paragon Offshore, at the time of the Spin-off, was properly funded, solvent and had appropriate liquidity and that the claims 
brought by the litigation trust are without merit. We intend to defend ourselves vigorously. However, there is inherent risk and substantial expense 
in litigation, and the amount of damages the plaintiff is seeking is substantial. If any of the litigation trust’s claims are successful, or if we elect 

30

to settle any claims (in part to reduce or eliminate the ongoing cost of defending the litigation and eliminate any risk of a larger judgment against 
us), 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. Because of our view of the merits of the claims and the significant discovery still to be conducted in the litigation, we 
are not currently able to make a reasonable estimation of the amount of possible loss we may incur, if any. Subsequent developments in the litigation 
may make such an estimation possible, in which case we may record a charge against our income when a loss is reasonably estimable. This may 
occur even though the litigation may still be ongoing. Any charge could be material and could have a material adverse effect on our financial 
condition and results of operations. It may also be materially different than any amount we are required to pay once the litigation is concluded. 

We have directors’ and officers’ indemnification coverage for the officers and directors who have been sued by the litigation trust. The 
insurers have accepted coverage for the director and officer claims and we are continuing to discuss with them the scope of their reimbursement 
of litigation expenses. In addition, at the time of the Spin-off, we had entity coverage, or “Side C” coverage, which was meant to cover certain 
litigation claims up to the coverage limit of $150.0 million, including litigation expenses. We have made a claim for coverage of the litigation 
trust’s claims against Noble under such entity insurance. The insurers have rejected coverage for these claims. We cannot predict the amount of 
claims and expenses we may incur, pay or settle in the Paragon Offshore litigation that such insurance will cover, if any.

Prior to the completion of the Spin-off, Noble-UK and Paragon Offshore entered into a series of agreements to effect the separation and 
Spin-off and govern the relationship between the parties after the Spin-off (the “Separation Agreements”), including the MSA and a 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 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.

The rejection and ultimate termination of the indemnity and related obligations under the Separation Agreements resulted in a number of 
accounting charges and benefits during 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, “Financial Statements 
and Supplementary Data, Note 11— Income Taxes.”

Impairment

As more thoroughly described in “Note 6— Loss on Impairment” to our consolidated financial statements, included in Part II, Item 8 of 
this Annual Report on Form 10-K, we evaluate our property and equipment for impairment whenever there are changes in facts which suggest 
that the value of the asset is not 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, 2018, 2017 and 2016, we recognized non-cash, before-tax impairment charges of $802.1 million, 
$121.6 million and $1.5 billion, 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.

31

There can be no assurance that we will not have to take additional impairment charges in the future if current depressed market conditions 

persist.

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, 2018, 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 for the three rigs contracted with Royal Dutch Shell plc (“Shell”) mentioned below, we utilize the idle period 
and floor rates as described in footnote (2) 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.

The table below presents the amount of our contract drilling services backlog and the percent of available operating days committed for 

the periods indicated:

Represents a twelve-month period beginning January 1, 2019.

As previously reported, three of our long-term drilling contracts with Shell, the Noble Bully II, 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. 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 at a special stacking rate. The Noble Bully II was idled at a rate 
of $200,000 per day, effective April 3, 2017. In April 2018, we agreed with Shell to extend the idle period for the Noble Bully II through 
December 31, 2018 at a revised rate of $230,000 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 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 their respective 
dayrate floor for the remaining contract term.

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, 2018, the backlog for the Noble Bully 
II totaled $405.6 million, all of which is included in backlog. As of the same date, the Noble Bully I had no backlog. Noble’s proportional 
interest in the backlog for these rigs totaled $202.8 million.

Some of our drilling contracts provide customers with certain early termination rights and, in limited cases, those termination rights 
require minimal or no notice and minimal financial penalties.

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.

32

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, 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— Our current backlog of contract drilling revenue may not be ultimately realized.”

For the year ended December 31, 2018, Shell, Saudi Arabian Oil Company and Equinor ASA represented approximately 52.2 percent, 19.8 

percent and 11 percent of our backlog, respectively.

Results of Operations 

2018 Compared to 2017

Net loss from continuing operations attributable to Noble-UK for the year ended December 31, 2018 was $885.1 million, or $3.59 per 
diluted share, on operating revenues of $1.1 billion, compared to a net loss from continuing operations for the year ended December 31, 2017 of 
$515.0 million, or $2.10 per diluted share, on operating revenues of $1.2 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, 2018 and 
December 31, 2017, 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 years ended December 31, 2018 and 2017, Noble-Cayman's operating loss was $40.7 million and $37.9 million
lower, respectively, than that of Noble-UK. The operating 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, 2018 and 2017:

We define utilization for a specific period as the total number of days our rigs are operating under contract, divided by the product of the 
total number of our rigs, including cold stacked rigs, and the number of calendar days in such period. Information reflects our policy of 
reporting on the basis of the number of available rigs in our fleet, excluding newbuild rigs under construction.

Information reflects the number of days that our rigs were operating under contract.

Average dayrates for the year ended December 31, 2017 include the impact of the valuation of certain contingent payments for the Noble 
Sam Croft and Noble Tom Madden contract settlement and termination by and among Freeport-McMoRan Inc., Freeport-McMoRan Oil 
& Gas LLC and one of our subsidiaries (“FCX Settlement”). We recognized a $14.4 million loss to the termination date valuation of 
certain contingent payments for the Noble Sam Croft and Noble Tom Madden related to the FCX Settlement. The loss in 2017 had a 
negative impact on the drillships’ average dayrates.

We record reimbursements from customers for out-of-pocket expenses as operating revenues and the related direct costs as operating 
expenses. Changes in the amount of these reimbursables generally do not have a material effect on our financial position, results of 
operations or cash flows. 

Operating Revenues. The $170.9 million decline in contract drilling services revenues for the year ended December 31, 2018 as compared 
to the same period of 2017 was composed of a $135.0 million decline due to fewer operating days and a $35.9 million decline due to lower dayrates. 
The decline in revenue was primarily due to our drillship and jackup fleet, which experienced declines in revenues of $66.5 million and $76.5 
million, respectively. Our semisubmersible fleet also experienced a decline in revenue of $27.9 million.

The $66.5 million revenue decline in our drillship fleet consists of a $101.7 million decline from lower dayrates, which was partially offset 
by a $35.2 million increase due to higher operating days for the year ended December 31, 2018 compared to the same period of 2017. The decline 
in average dayrates was primarily related to the Noble Bully II, which remained idle during the current period but operated for a portion of the 
prior period. The increase in operating days was primarily related to the reactivation of the Noble Tom Madden in the fourth quarter of 2018, offset 
by the stacking of the Noble Bully I in the second quarter of 2017.

The $76.5 million revenue decline in our jackup fleet is primarily attributable to a $91.5 million decline in revenues due to certain of our 
jackup rigs not operating for the year ended December 31, 2018, which was partially offset by a $15.0 million increase in revenues associated 
with favorable dayrate changes across the jackup fleet. The decrease in operating days during the current period was the result of the retirement 
and subsequent sale of the Noble David Tinsley, the retirement of the Noble Alan Hay and a decrease in operating days for the Noble Mick O'Brien 
and for the Noble Sam Hartley, which was stacked in early 2018 and reactivated in late 2018. The $27.9 million decline in semisubmersible 
revenues was primarily due to a decrease in both dayrate and operating days on the Noble Paul Romano, which was warm stacked in early 2018.

Operating Costs and Expenses. Contract drilling services costs decreased $13.0 million for the year ended December 31, 2018 as compared 
to the same period of 2017. Rigs that were operating in the prior period, but were idle or stacked most of the current period contributed $20.5 
million to the decrease in operating costs, and rigs that operated in the prior period but were subsequently retired contributed $18.7 million to the 
decrease in operating costs. In addition to these rig costs declines, operations support costs decreased $9.2 million for the year ended December 31, 
2018, of which $7.6 million related to reduction of employee-related expenses. These decreases were offset by $64.1 million of cost increases as 
certain rigs prepared and returned to operations and experienced higher operating days in the current period. Operating costs increases were 
recognized across all costs categories, but were primarily attributable to crew-related expenses ($48.4 million) and repairs, maintenance, and other 
rig-related costs ($15.7 million). Contract Drilling Services costs in 2017 included non-recurring charges of $28.7 million related to damages 
sustained by two rigs during Hurricane Harvey in the U.S. Gulf of Mexico region along with a charge related to the write-off an uncollectible 
receivable held by a Paragon Offshore entity in Mexico that is expected to be liquidated.

Depreciation and amortization decreased $57.5 million for the year ended December 31, 2018 as compared to the same period of 2017. 

The decline was due to the effect of rig impairments recorded during the second quarter of 2018 and the fourth quarter of 2017.

Loss on Impairments. We recorded a loss on impairment of $802.1 million for the year ended December 31, 2018 as compared to a loss 
on impairment of $121.6 million for the same period of 2017. We evaluate our property and equipment for impairment whenever there are changes 

34

in facts which suggest that the value of the asset is not recoverable. In connection with the preparation of our financial statements for the second 
quarter  of  2018  and  the  year  ended  December 31,  2018,  we  conducted  a  review  of  our  fleet. The  review  included  an  assessment  of  certain 
assumptions, including future marketability of each unit in light of its current technical specifications. Based upon our impairment analysis, we 
impaired the carrying values to estimated fair values for the Noble Bully I, Noble Dave Beard, Noble Gene House, Noble Joe Beall, Noble Paul 
Romano, and certain capital spare equipment. 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 $1.6 million during the year ended December 31, 

2018 as compared to the same period of 2017, primarily due to higher employee-related costs.

Interest Expense. Interest expense increased $5.6 million during the year ended December 31, 2018 as compared to the same period of 
2017. This increase was primarily due to the issuance of our Senior Notes due 2026 (the “2026 Notes”) in January 2018, an increase in interest 
rates on certain of our senior notes due to the downgrading of our credit rating, the entry into the 2017 Credit Facility (as defined herein) on 
December 21, 2017, and the entry into the seller-financed secured loan for the purchase of the Noble Johnny Whitstine. These increases were 
partially offset by the retirement of a portion of various tranches of our senior notes as a result of tender offers and open market repurchases 
throughout 2018, the maturity of our Senior Notes due 2018 (the “2018 Notes”) and the redemption of our remaining Senior Notes due 2019 (the 
“2019 Notes”). For additional information, see Part II, Item 8, “Financial Statements and Supplementary Data, Note 7— Debt.”

Income Tax Provision. Our income tax provision decreased by $149.3 million for the year ended December 31, 2018 as compared to the 
same period of 2017. The decrease was primarily due to prior period discrete tax items of $151.2 million related to tax restructuring and the impact 
of the Act and to various tax benefits in the current period including the tax impact on asset impairments of $35.6 million, U.S. return-to-provision 
adjustment of $24.9 million, UK return-to-provision adjustment of $9.1 million and a U.S. disallowed interest carryover of $51.4 million. These 
decreases were partially offset by an $84.2 million increase in tax expense in the current period attributable to a higher pre-tax loss and a lower 
worldwide effective tax rate as compared to the prior period. The increase in the current period pre-tax loss generated a $19.6 million tax benefit 
and the lower current period worldwide effective tax rate reduced the tax benefit by $103.7 million. The decrease in the worldwide effective tax 
rate in the current period is primarily a result of the geographic mix of income and sources of revenue.

2017 Compared to 2016 

Net loss from continuing operations attributable to Noble-UK for the year ended December 31, 2017 was $515.0 million, or $2.10 per 
diluted share, on operating revenues of $1.2 billion, compared to a net loss from continuing operations for the year ended December 31, 2016 of 
$929.6 million, or $3.82 per diluted share, on operating revenues of $2.3 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, 2017 and 
December 31, 2016, 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 years ended December 31, 2017 and 2016, Noble-Cayman’s operating loss was $37.9 million and $29.7 million 
lower, respectively, than that of Noble-UK. The operating 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, 2017 and 2016:

We define utilization for a specific period as the total number of days our rigs are operating under contract, divided by the product of the 
total number of our rigs, including cold stacked rigs, and the number of calendar days in such period. Information reflects our policy of 
reporting on the basis of the number of available rigs in our fleet, excluding newbuild rigs under construction.

Information reflects the number of days that our rigs were operating under contract.

Average dayrate for the year ended December 31, 2016 includes $16.4 million in contract drilling services revenue related to the Noble 
Tom Prosser contract cancellation with Quadrant Energy Australia Limited. The additional contract drilling services revenue in 2016 had 
a positive impact on the jackups’ average dayrates.

Average dayrates include a $14.4 million loss in the year ended December 31, 2017 and a $14.4 million gain in the year ended December 
31, 2016, in respect of the termination date valuation of certain contingent payments for the Noble Sam Croft and Noble Tom Madden 
related to the FCX Settlement. The loss in 2017 had a negative impact and the gain in 2016 had a positive impact on the drillships’ average 
dayrates.

expenses. Changes in the amount of these reimbursables generally do not have a material effect on our financial position, results of 
operations or cash flows.

Operating Revenues. The $1.0 billion decline in contract drilling services revenues for the year ended December 31, 2017 as compared to 
the same period of 2016 was composed of an $851.6 million decline from lower dayrates and a $183.6 million decline due to fewer operating 
days. The contract drilling services revenues decline was primarily due to our drillship and semisubmersible fleets, which experienced declines 
in revenues of $975.7 million and $109.3 million, respectively, and was partially offset by revenue increases in our jackup fleet of $49.8 million. 

The $975.7 million revenue decline in our drillship fleet for the year ended December 31, 2017 as compared to the same period of 2016 
consists of a $523.1 million decline from lower dayrates and a $452.6 million decline due to fewer operating days. The decline in average dayrates 
was primarily related 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 and Noble Sam Croft, 
whose contracts were terminated in May 2016.

The $109.3 million revenue decline in our semisubmersible fleet for the year ended December 31, 2017 as compared to the same period 
of 2016 consists of a $36.6 million decline from lower dayrates and a $72.7 million decline due to fewer operating days. The decline in both 
average dayrates and operating days as compared to 2016 was attributable to 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 increase in our jackup fleet is primarily attributable to an increase in operating days on the Noble Mick O'Brien 

and Noble Regina Allen as well as the startup of the newbuild Noble Lloyd Noble.

Operating Costs and Expenses. Contract drilling services costs decreased $234.8 million for the year ended December 31, 2017 as compared 
to the same period of 2016. Of the decrease, $179.0 million was due to rigs that operated during 2016 being idle during 2017. An additional $113.1 
million decrease in cost was 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 costs of $28.1 million, and rig mobilization costs of $3.0 million. These 
cost decreases were partially offset by the startup of the Noble Lloyd Noble, a greater number of operating days for contracted rigs during 2017 
and the write-off of a $14.4 million customer receivable during 2017.

Depreciation and amortization decreased $63.2 million for the year ended December 31, 2017 as compared to the same period of 2016. 
The decline was due to the effect of rig retirements and impairments during 2016, partially offset by the effect of the Noble Lloyd Noble being 
placed into service during November 2016.

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 the same period of 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.”

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 was to lower current tax expense. This increase was partially offset by the tax effect of the FCX 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 2017, primarily from our 
geographical mix of pre-tax income.

Liquidity and Capital Resources

Overview

Net cash provided by operating activities was $171.9 million for the year ended December 31, 2018 and $416.7 million for the year ended 
December 31, 2017. The decrease in net cash provided by operating activities for the year ended December 31, 2018 was primarily attributable 
to a reduction in operating activity during 2018. We had working capital of $293.6 million and $446.0 million at December 31, 2018 and December 
31, 2017, respectively.

Net cash used in investing activities for the year ended December 31, 2018 was $189.4 million as compared to $118.3 million for the year 
ended December 31, 2017. The variance primarily relates to the purchase of the Noble Johnny Whitstine, the reactivation of the Noble Clyde 
Boudreaux, Noble Tom Madden, and Noble Sam Croft and various major projects in the current period.

Net cash used in financing activities for the year ended December 31, 2018 was $269.4 million as compared to $361.2 million for the year 
ended December 31, 2017. During the current period, our primary uses of cash included retirement of a portion of the 2020 Notes, 2021 Notes, 
2022 Notes, Senior Notes due 2024 (the “2024 Notes”), Senior Notes due 2040 (the “2040 Notes”), Senior Notes due 2041 (the “2041 Notes”), 
and Senior Notes due 2042 (the “2042 Notes”) in tender offers and open market purchases, repayment at maturity of the 2018 Notes and redemption 
of the 2019 Notes, which amounts were partially offset by the issuance of the 2026 Notes.

Our principal source of capital in the current period was cash generated from operating activities coupled with the $750.0 million 2026

Notes offering in January 2018. Cash on hand during the current period was primarily used for the following:

• 
• 

• 

normal recurring operating expenses;
retirement of a portion of various tranches of our senior notes in tender offers, repayment at maturity of the 
2018 Notes and redemption of the 2019 Notes; 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
repayments of debt and interest.

37

We currently expect to fund these cash flow needs with cash generated by our operations, cash on hand, borrowings under our Credit 
Facilities (as defined herein) and potential issuances of equity or long-term debt. However, to adequately cover our expected cash flow needs, we 
may require capital in excess of the amount available from these sources, and we may seek additional sources of liquidity and/or delay or cancel 
certain discretionary capital expenditures or other payments as necessary.

At December 31, 2018, we had a total contract drilling services backlog of approximately $2.4 billion, which includes a commitment of 

62.0 percent of available days for 2019. For additional information regarding our backlog, see “—Contract Drilling Services Backlog.”

Capital Expenditures

Capital expenditures totaled $281.3 million, $111.1 million and $659.9 million for the years ended December 31, 2018, 2017 and 2016, 

respectively. Capital expenditures during 2018 consisted of the following:

• 
• 
• 
• 

$82.7 million for sustaining capital;
$75.6 million in major projects, including reactivations;
$29.2 million in subsea and other related projects; and
$93.8 million to purchase the Noble Johnny Whitstine (inclusive of cash paid and seller financing).

Our total capital expenditure estimate for 2019 is approximately $303.9 million, which is currently anticipated to be spent as follows:

• 
• 
• 
• 

$90.3 million for sustaining capital;
$96.4 million in major projects, including reactivations;
$33.4 million in subsea and other related projects; and
$83.8 million to purchase the Noble Joe Knight (inclusive of cash paid and seller financing).

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, 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, possible refurbishment and reactivation of rigs and changes 
in design criteria or specifications during repair or construction.

Share Capital

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 law. 
Therefore, Noble-UK is not permitted to pay dividends out of share capital, which includes share premium. Noble has 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.

At our 2018 Annual General Meeting, shareholders approved a proposal to allow our Board of Directors to increase share capital through 
the issuance of up to 82.2 million ordinary shares (at current nominal value of $0.01 per share). The right of our directors to allot shares will expire 
at the end of our 2019 Annual General Meeting unless we seek an extension from shareholders at that time. No shares were allotted during the 
year ended December 31, 2018.

Share Repurchases 

Under UK law, the Company is only permitted to purchase its own shares by way of an “off-market purchase” in a plan approved by 
shareholders. We currently do not have shareholder authority to repurchase shares. During the years ended December 31, 2018, 2017 and 2016, 
we did not repurchase any of our shares. 

Credit Facilities 

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 is guaranteed by 
our indirect, wholly-owned subsidiaries, Noble Holding (U.S.) LLC (“NHUS”) and Noble Holding International Limited (“NHIL”) (the “2015 
Credit Facility”). At December 31, 2017, the 2015 Credit Facility also provided us with the ability to issue up to $500.0 million in letters of credit. 

On December 19, 2017, we entered into the First Amendment and Consent and Successor Agent Agreement (the “Amendment”) amending 
the 2015 Credit Facility. 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 termination 
of the 2015 Credit Facility's letter of credit sub-facility. The maturity of the 2015 Credit Facility remains January 2020. As a result of the 2015 

38

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. At December 31, 2018, we had no borrowings outstanding or letters of credit issued under the 2015 Credit Facility.

2017 Credit Facility

On December 21, 2017, Noble Cayman Limited, a Cayman Islands company and a wholly-owned indirect subsidiary of Noble-Cayman 
(“NCL”); Noble International Finance Company, a Cayman Islands company and a wholly-owned indirect subsidiary of Noble-Cayman (“NIFCO”); 
and Noble Holding UK Limited, a company incorporated under the laws of England and Wales and a wholly-owned direct subsidiary of Noble-
UK (“NHUK”), as parent guarantor, entered into a new senior unsecured credit agreement (the “2017 Credit Facility” and, together with the 2015 
Credit Facility, the “Credit Facilities”). The maximum aggregate amount of commitments under the 2017 Credit Facility is approximately $1.5 
billion. 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. The 2017 Credit Facility will mature in January 2023. Borrowings may be used for working capital 
and other general corporate purposes. The 2017 Credit Facility provides for a letter of credit sub-facility currently in the amount of $15.0 million, 
with the ability to increase such amount up to $500.0 million with the approval of the lenders. At December 31, 2018, we had $3.4 million of 
performance letters of credit outstanding under the 2017 Credit Facility. At December 31, 2018, other than the performance letters of credit, we 
had no borrowings outstanding under the 2017 Credit Facility.

 Both of our Credit Facilities have provisions which vary the applicable interest rates for borrowings based upon our debt ratings. We also 
pay a facility fee under the 2015 Credit Facility on the full commitments thereunder (used or unused) and a commitment fee under the 2017 Credit 
Facility on the daily unused amount of the underlying commitments, in each case which varies depending on our credit ratings. At December 31, 
2018, the interest rates in effect under our Credit Facilities were the highest permitted interest rates under those agreements.

Debt Issuance

In January 2018, we issued $750.0 million aggregate principal amount of the 2026 Notes through our indirect wholly-owned subsidiary, 
NHIL. The net proceeds of the offering of approximately $737.4 million, after expenses, were used to retire a portion of our near-term senior notes 
in a related tender offer.

The indenture for the 2026 Notes contains certain covenants and restrictions, including, among others, restrictions on our subsidiaries’ 
ability 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.

Seller Financing of Rig

In September 2018, we purchased the Noble Johnny Whitstine for $93.8 million with a $60.0 million seller-financed secured loan (the 
“Seller Loan”). The Seller Loan has a term of four years and requires a 5% principal payment at the end of the third year with the remainder of 
the principal due at the end of the term. The Seller Loan bears 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 Seller Loan. Based on the terms of the Seller Loan, the 1.25% paid-in-kind interest rate is accelerated into the 
first year, resulting in an overall first year interest rate of 8.91%, of which only 4.25% is payable in cash. Thereafter, the paid-in-kind interest ends 
and the cash interest rate of 4.25% is payable for the remainder of the term.

The Seller Loan is guaranteed by Noble-Cayman and is secured by a mortgage on the Noble Johnny Whitstine and by the pledge of the 
shares of the single-purpose entity that owns the rig. The Seller Loan contains debt to total capitalization ratio and minimum liquidity financial 
covenants substantially similar to the 2017 Credit Facility, and an asset and revenue covenant substantially similar to the 2026 Notes as well as 
other covenants and provisions customarily found in secured transactions. The Seller Loan requires immediate repayment on the occurrence of 
certain events, including the termination of the drilling contract entered into at the time of the purchase of the rig.

On February 14, 2019, we exercised our option to purchase a new jackup rig, to be known as the Noble Joe Knight, and we expect to 
complete the purchase in late February 2019. The purchase of the Noble Joe Knight will be partially funded with cash and a seller loan on terms 
similar to the Noble Johnny Whitstine.

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 below investment grade. As a result of these downgrades, we experienced interest rate increases during 2016 and 2017 on 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 

39

increased the interest rates on the 2025 Notes and the 2045 Notes to 7.95% and 8.95%, respectively, effective April 2018. These senior notes have 
reached the contractually defined maximum interest rate set for each rating agency and no further interest rate increases are possible. The interest 
rates on these senior notes may be decreased if our debt ratings were to be raised by either rating agency above specified levels. Our other outstanding 
senior notes do not contain provisions varying applicable interest rates based upon our credit ratings.

Debt Tender Offers, Repayments and Open Market Repurchases

In January 2018, we commenced cash tender offers for the 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 and cash on hand. As a result of this transaction, we recognized a net loss of approximately $3.5 
million.

In February 2018, we redeemed the remaining principal amount of $61.9 million of the 2019 Notes for approximately $65.3 million, plus 

accrued interest. As a result of this transaction, we recognized a net loss of approximately $3.5 million.

In March 2018, we repaid the remaining aggregate principal amount of $126.6 million of the 2018 Notes at maturity using cash on hand.

In March 2018, we purchased $9.5 million aggregate principal amount of various tranches of our senior notes for approximately $8.7 

million, plus accrued interest, as open market repurchases and recognized a net gain of approximately $0.5 million.

In August 2018, we purchased $0.4 million aggregate principal amount of the 2042 Notes for approximately $0.3 million, plus accrued 

interest, as open market repurchases and recognized a net gain of approximately $0.1 million.

In October 2018, we purchased $27.4 million aggregate principal amount of various tranches of our senior notes for approximately $20.2 

million, plus accrued interest, as open market repurchases and recognized a net gain of approximately $6.9 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 the end of each fiscal quarter.

The 2017 Credit Facility contains certain financial covenants applicable to NHUK and its subsidiaries, including (i) a covenant restricting 
debt to total tangible capitalization to not greater than 0.55 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 (as defined in the 2017 Credit Facility) 
of Marketed Rigs (as defined in the 2017 Credit Facility) to the sum of commitments under the 2017 Credit Facility 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 (as 
defined in the 2017 Credit Facility) that are directly wholly owned by the borrowers and guarantors to (B) the Rig Value of the Closing Date Rigs 
owned by 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. In addition, on January 19, 2018, certain indirect 
subsidiaries of Noble-UK became guarantors under the 2017 Credit Facility, including Noble Dave Beard Limited, Noble Drilling (TVL) Ltd., 
Noble Resources Limited, Noble SA Limited, Noble BD LLC, Noble Drilling Holding LLC, Noble Drilling International GmbH, Noble Leasing 
(Switzerland) GmbH, and Noble Leasing III (Switzerland) GmbH. Certain other subsidiaries of Noble-UK may be required from time to time to 
guarantee the obligations of the borrowers under the 2017 Credit Facility in order maintain compliance with the Guarantor Ratio Covenants.

The 2017 Credit Facility contains additional restrictive covenants generally applicable to NHUK and its subsidiaries, including 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 of the 2017 Credit Facility, sale and leaseback transactions and transactions with affiliates.

In addition to the covenants from the Credit Facilities noted above, the covenants from the 2026 Notes described under “—Debt Issuance” 
above and the covenants from the Seller Loan described under “—Seller Financing of Rig” above, the indentures governing our outstanding senior 
unsecured notes contain covenants that place restrictions on certain merger and consolidation transactions, unless we are the surviving entity or 
the other party assumes the obligations under the indenture, and on the ability to sell or transfer all or substantially all of our assets. There are also 
restrictions on incurring or assuming certain liens and on entering into sale and lease-back transactions.

At December 31, 2018, our debt to total tangible capitalization ratio under our 2017 Credit Facility was approximately 0.48 and we were 
in compliance with all applicable debt covenants. We continually monitor compliance with the covenants under our Credit Facilities, senior notes 
and Seller Loan, and expect to remain in compliance throughout 2019.

Tax reserves are included in “Other” due to the difficulty in making reasonably reliable estimates of the timing of cash settlements to 
taxing authorities. See Part II, Item 8, “Financial Statements and Supplementary Data, Note 11— Income Taxes.”

In February 2019, we amended the lease for our Sugar Land office to extend the lease for an additional ten years and to reduce the rented 
space. The above table does not include this lease amendment. 

At December 31, 2018, we had other commitments that we are contractually obligated to fulfill with cash if the obligations are called. 
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.

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, “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. (“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,  those  of  our  wholly-owned  subsidiaries  and  entities  in  which  we  hold  a 
controlling financial interest. Our consolidated financial statements include the accounts of two joint ventures, in each of which we own a 50 
percent interest. Our ownership interest meets the definition of variable interest under Financial Accounting Standards Board (“FASB”) codification 
and we have determined that we are the primary beneficiary. Intercompany balances and transactions have been eliminated in consolidation.

The combined carrying amount of the Bully-class drillships at December 31, 2018 and 2017 totaled $0.7 billion and $1.3 billion, respectively. 
These assets were primarily funded through partner equity contributions. Cash held by the Bully joint ventures totaled approximately $45.2 million 
at December 31, 2018 as compared to approximately $41.6 million at December 31, 2017.

41

 
 
 
 
 
Basis of Presentation-U.K. Companies Act 2006 Section 435 Statement

The accompanying consolidated financial statements have been prepared in accordance with US GAAP, which the Board of Directors 
considers 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, 2018 and 2017, we had $209.1 million and $83.5 million
of construction-in-progress, respectively. Such amounts are included in “Property and equipment, at cost” in the accompanying 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 years ended December 31, 2018, 2017 and 2016, there was $2.9 million, zero and $22.4 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 $146.3 million and $149.3 million at December 31, 2018 and 2017, respectively. 
Depreciation expense from continuing operations related to overhauls and asset replacement totaled $66.9 million, $79.2 million and $86.0 million
for the years ended December 31, 2018, 2017 and 2016, 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, 2018, 2017 and 2016, we recognized a non-cash loss on impairment of $802.1 million, $121.6 million, 
and $1.5 billion, respectively, related to our long-lived assets. See Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition 
and  Results  of  Operations—  Executive  Overview,”  and  Part  II,  Item  8,  “Financial  Statements  and  Supplementary  Data,  Note  6—  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 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 

42

 
 
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.

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 corresponding goods 
and services are to be consumed.

Deferred revenues from drilling contracts totaled $80.8 million and $114.3 million at December 31, 2018 and 2017, 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 $47.7 million at December 31, 2018 as compared to $55.7 

43

 
 
 
 
 
 
 
 
million at December 31, 2017 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.

We record reimbursements from customers for “out-of-pocket” expenses as revenues and the related direct cost as operating expenses.

Income Taxes

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. We cannot predict or provide assurance as to the ultimate outcome of any existing or future assessments. Our net 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 Company 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 Internal Revenue Service (“IRS”) began its examination of our tax reporting in the U.S. for the taxable years ended 
December 31, 2010 and 2011. The IRS examination team has completed its examination of our 2010 and 2011 U.S. tax returns and proposed 
adjustments and deficiencies with respect to certain items that were reported by us for the 2010 and 2011 tax years. On December 19, 2016, we 
received the Revenue Agent Report from the IRS. We believe that we have accurately reported all amounts in our tax returns, and have submitted 
administrative protests with the IRS Office of Appeals contesting the examination team’s proposed adjustments. We intend to vigorously defend 
our reported positions, and believe the ultimate resolution of the adjustments proposed by the IRS examination team 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.

Audit claims of approximately $50.7 million attributable to income and other business taxes were assessed against Noble entities in Mexico 
related to tax years 2005 and 2007. We intend to vigorously defend our reported positions, and believe the ultimate resolution of the audit claims 
will not have a material adverse effect on our consolidated financial statements.

On December 22, 2017, the President of the United States signed the 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. The Company 
recognized the income tax effects of the Act in its 2017 financial statements, including $109.0 million of tax benefit related 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. During the fourth quarter of 2017, the Act resulted in the write-down of our U.S. net deferred tax liabilities. In 
accordance with the guidance issued in Staff Accounting Bulletin No. 118, during the third quarter of 2018, we finalized our provisional amounts 
recorded as we completed our technical analysis, computations and tax law interpretations and filed our 2017 U.S. tax return. As a result, we 
recognized an additional tax benefit of $24.9 million. 

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, of its foreign subsidiaries. The Company 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, 2018 and 2017, loss reserves for personal injury and protection claims totaled $22.4 million and $22.0 million, respectively, 
and such amounts are included in “Other current liabilities” 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 

44

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 Statements and Supplementary Data, Note 15— 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” 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, 
2018, we had no borrowings outstanding or letters of credit issued under the 2015 Credit Facility. At December 31, 2018, we had $3.4 million of 
performance letters of credit outstanding under the 2017 Credit Facility. At December 31, 2018, other than the performance letters of credit, we 
had no borrowings outstanding under the 2017 Credit Facility.

During 2016 and 2017, we experienced debt rating downgrades by Moody’s Investors Service and S&P Global Ratings, which reduced our 
debt ratings below investment grade. As a result of these downgrades, we experienced interest rate increases during 2016 and 2017 on our Senior 
Notes due 2018, 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 increased the interest rates on the 2025 Notes and the 2045 Notes to 7.95% and 8.95%, respectively, effective April 2018. These 
senior notes have reached the contractually defined maximum interest rate set for each rating agency and no further interest rate increases are 
possible. The interest rates on these senior notes may be decreased if our debt ratings were to be raised by either rating agency above specified 
levels. Our other outstanding senior notes 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 $2.9 billion and $3.4 billion at December 31, 2018 and December 31, 
2017, respectively. The decrease in the fair value of debt relates to a reduction in total principal amount outstanding due to our debt repayments 
during 2018, partially offset by our debt issuance and changes in market expectations for interest rates and perceptions of our credit risk.

Foreign Currency Risk

Although we are a UK company, we define foreign currency as any non-U.S. denominated currency. Our functional currency is the U.S. 
Dollar. However, outside the United States, a portion of our expenses are incurred in local currencies. Therefore, when the U.S. Dollar weakens 
(strengthens) in relation to the currencies of the countries in which we operate, our expenses reported in U.S. 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 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 Sheets 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 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 have historically settled monthly in the operations’ 
respective  local  currencies. All  of  these  contracts  had  a  maturity  of  less  than  12  months. There  were  no  foreign  currency  forward  contracts 
outstanding or entered into during the year ended December 31, 2018.

45

Market Risk

We have a U.S. noncontributory defined benefit pension plan that covers certain salaried employees and a U.S. 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. 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. plans when required. 
The benefit amount that can be covered by the qualified U.S. plans is limited under ERISA and the Internal Revenue Code 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. plan. We refer to the qualified U.S. plans and the excess benefit plan collectively as the “U.S. plans.”

In addition to the U.S. plans, Noble Drilling (Land Support) Limited, an indirect, wholly-owned subsidiary of Noble-UK, 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 (referred to as 
our “non-U.S. plan”). Benefits are based on credited service and employees’ compensation, as defined by the non-U.S. plan.

Changes in market asset values related to the pension plans noted above could have a material impact upon our Consolidated Statements 

of Comprehensive Income (Loss) and could result in material cash expenditures in future periods.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

To the Board of Directors and
Shareholders of Noble Corporation plc

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Noble Corporation plc and its subsidiaries (the “Company”) as of 
December 31, 2018 and 2017, and the related consolidated statements of operations, comprehensive income (loss), cash flows, and equity for 
each of the three years in the period ended December 31, 2018, 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, 2018, 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, 2018 and 2017 and the results of its operations and its cash flows for each of the three years in the period ended 
December 31, 2018 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, 2018, 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'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) 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.

48

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.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and
Shareholder of Noble Corporation

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Noble Corporation and its subsidiaries (the “Company”) as of December 31, 
2018 and 2017, and the related consolidated statements of operations, comprehensive income (loss), cash flows, and equity for each of the three 
years in the period ended December 31, 2018, 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, 2018, 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, 2018 and 2017 and the results of its operations and its cash flows for each of the three years in the period ended 
December 31, 2018 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, 2018, 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'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) 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.

55

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.

NOBLE CORPORATION PLC AND SUBSIDIARIES
NOBLE CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Unless otherwise indicated, dollar amounts in tables are in thousands)

Note 1— Organization and Significant Accounting Policies 

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. As of December 31, 2018, our fleet of 24 drilling rigs consisted of eight drillships, four semisubmersibles and 
12 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. 

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 of its business 
through Noble-Cayman and its subsidiaries.

Principles of Consolidation

The  consolidated  financial  statements  include  our  accounts,  those  of  our  wholly-owned  subsidiaries  and  entities  in  which  we  hold  a 
controlling financial interest. Our consolidated financial statements also include the accounts of two joint ventures, in each of which we own a 50 
percent interest. Our ownership interest meets the definition of variable interest under Financial Accounting Standards Board (“FASB”) codification 
and we have determined that we are the primary beneficiary. Intercompany balances and transactions have been eliminated in consolidation.

The combined carrying amount of the Bully-class drillships at December 31, 2018 and 2017 totaled $0.7 billion and $1.3 billion, respectively. 
These assets were primarily funded through partner equity contributions. Cash held by the Bully joint ventures totaled approximately $45.2 million 
at December 31, 2018 as compared to approximately $41.6 million at December 31, 2017.

Revision of Prior Period Financial Statements

During the preparation of our 2018 financial statements, we identified a computational error that resulted in misstatements of certain line 
items on the Consolidated Statements of Cash Flows for Noble Corporation plc and Noble Corporation (Cayman) for the years ended December 31, 
2017 and 2016. These errors did not impact our cash, cash equivalents and restricted cash balances. We assessed the materiality of the misstatements 
and concluded the misstatements were immaterial to the previously issued financial statements. 

We  have  revised  the  Consolidated  Statements  of  Cash  Flows  for  the  years  ended  December 31,  2017  and  2016. The  impacts  on  the 

Consolidated Statements of Cash Flows and related notes to the financial statements are presented below:

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, 2018.

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, 2018, our restricted cash 
balance consisted of $0.7 million of restricted cash accounts for interest payments associated with our financing of the Noble Johnny Whitstine, 
recorded in Prepaid expenses and other current assets. As of December 31, 2017 and 2016, we had no restricted cash balances.

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, 2018 and 2017 was $2.2 million and $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 $52.1 million and $25.5 million of capital accruals as of December 31, 2018 and 2017, respectively.

63

 
 
NOBLE CORPORATION PLC AND SUBSIDIARIES
NOBLE CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Unless otherwise indicated, dollar amounts in tables are in thousands)

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 which suggest that the value of the asset is 

not recoverable. 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. 

64

 
 
 
 
 
 
 
NOBLE CORPORATION PLC AND SUBSIDIARIES
NOBLE CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Unless otherwise indicated, dollar 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 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 corresponding goods 
and services are to be consumed. 

Deferred revenues from drilling contracts totaled $80.8 million and $114.3 million at December 31, 2018 and 2017, 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 $47.7 million at December 31, 2018 as compared to $55.7 
million at December 31, 2017 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.

We record 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 circumstances, we expect that, due to changing demands of the offshore drilling markets 
and the ability to redeploy our offshore 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 U.S., UK or 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 laws in effect in various countries

at the time that the expense was incurred. If the IRS or other taxing authorities do not agree with our assessment of the effects of such laws, treaties 
and regulations, this could have a material adverse effect on us including the imposition of a higher effective tax rate on our worldwide earnings 
or a reclassification of the tax impact of our significant corporate restructuring transactions. The Company 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.

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. The Company recognized 
the income tax effects of the Act in its 2017 financial statements, including $109.0 million of tax benefit related 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. During the fourth quarter of 2017, the Act resulted in the write-down of our U.S. net deferred tax liabilities. In accordance 
with the guidance issued in Staff Accounting Bulletin No. 118 (SAB No. 118), during the third quarter of 2018, we finalized our provisional 
amounts recorded as we completed our technical analysis, computations and tax law interpretations and filed our 2017 U.S. tax return. As a result, 
we recognized an additional tax benefit of $24.9 million. See “Note 11— 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, of its foreign subsidiaries. The Company 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, 2018 and 2017, loss reserves for personal injury and protection claims totaled $22.4 million and $22.0 million, respectively, 
and such amounts are included in “Other current liabilities” 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.

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 provisions and changes to our disclosures accordingly to reflect the 
impact of negotiations, settlements, rulings, advice of legal counsel, and updated information. Significant judgement is required to determine both 
the probability and the estimated amount.

Discontinued Operations

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 of the ordinary shares of its wholly-owned subsidiary, Paragon Offshore plc (“Paragon 

66

 
NOBLE CORPORATION PLC AND SUBSIDIARIES
NOBLE CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Unless otherwise indicated, dollar amounts in tables are in thousands)

Offshore”), to the holders of Noble’s ordinary shares. Paragon Offshore, which had been reflected as continuing operations in our consolidated 
financial statements prior to the Spin-off, meets the criteria for being reported as discontinued operations and has been reclassified as such in our 
results of operations.

Prior to the completion of the Spin-off, Noble-UK and Paragon Offshore entered into a series of agreements to effect the separation and 
Spin-off  and  govern  the  relationship  between  the  parties  after  the  Spin-off  (the  “Separation Agreements”),  including  the  Master  Separation 
Agreement (the “MSA”) and the Tax Sharing Agreement (the “TSA”). During the year ended December 31, 2017, we recorded a non-cash loss 
of $1.5 million in “Net loss from discontinued operations, net of tax” on our Consolidated Statement of Operations from the effects of Paragon 
Offshore's rejection of the Separation Agreements. For additional information related to the Spin-off, refer to “Note 15— Commitments and 
Contingencies.”

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 May 2014, the FASB issued Accounting Standards Update (“ASU”) No. 2014-09, which creates 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. 2014-09 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.” Under the new guidance, revenue is recognized when a customer obtains control of promised 
goods or services and in an amount that reflects the consideration the entity expects to receive in exchange for those goods or services.

We adopted ASU 2014-09 and its related amendments, or collectively Topic 606, effective January 1, 2018 using the modified retrospective 
implementation method. Accordingly, we have applied the five-step method outlined in Topic 606 for determining when and how revenue is 
recognized to all contracts that were not completed as of the date of adoption. Revenues for reporting periods beginning after January 1, 2018 are 
presented under Topic 606, while prior period amounts have not been adjusted and continue to be reported under the previous revenue recognition 
guidance. For contracts that were modified before the effective date, we have considered the modification guidance within the new standard and 
determined that the revenue recognized and contract balances recorded prior to adoption for such contracts were not impacted. While Topic 606 
requires additional disclosure of the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers, its 
adoption has not had a material impact on the measurement or recognition of our revenues. Our modified retrospective adoption, for which we 
were not required to make any material changes to the prior year presentation, did not have a material effect on our consolidated financial statements. 

In October 2016, the FASB issued ASU No. 2016-16, which amends ASC Topic 740, “Income Taxes.” The amendments in this update 
improve 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. We adopted the new standard effective January 1, 2018 under the modified 
retrospective approach. Accordingly, we recorded deferred charges of approximately $148.4 million to “Retained earnings” on our Consolidated 
Balance Sheets.

In March 2017, the FASB issued ASU No. 2017-07, which amends ASC Topic 715, “Compensation —Retirement Benefits; Improving the 
Presentation of Net Periodic Pension Cost and Postretirement Benefits Cost.” The amendments in this update require that an employer disaggregate 
the service cost component from the other components of net benefit cost for an entity's defined benefit pension and other postretirement plans. 
The amendments also provide explicit guidance on how to present the service cost component and the other components of net benefit cost in the 
income statement and allow only the service cost component of net benefit cost to be eligible for capitalization. The amendments in this update 
require that an employer report the service cost component in the same line item or items as other compensation costs arising from services rendered 
by the pertinent employees during the period. The other components of net benefit costs, as defined in paragraphs 715-30-35-4 and 715-60-35-9, 
are required to be presented in the income statement separately from the service cost component and outside of income from operations. We 

67

NOBLE CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Unless otherwise indicated, dollar amounts in tables are in thousands)

adopted ASU No. 2017-07 effective January 1, 2018 and accordingly, we have made certain reclassifications between our “Contract drilling 
services” costs and “Interest income and other, net” on our Consolidated Statement of Operations.

In February 2018, the FASB issued ASU No. 2018-02, 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
with early application permitted. We elected to adopt the new standard effective January 1, 2018 under the modified retrospective approach. 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 was recognized. As a result of the retrospective application, we reduced “Accumulated other comprehensive loss” in our Consolidated 
Balance Sheet with a cumulative adjustment to “Retained earnings” of approximately $5.5 million.

In August 2018, the FASB issued ASU No. 2018-15, which amends ASC Subtopic 350-40, “Intangibles—Goodwill and Other—Internal
—Use Software.” The amendments in this update require an entity in a hosting arrangement that is a service contract to capitalize implementation 
costs. Entities are to follow the guidance in ASC Subtopic 350-40 to determine which implementation costs to capitalize as an asset related to the 
service contract and which costs to expense. The amendment also requires the entity to expense these capitalized implementation costs over the 
term of the hosting arrangement. We elected to early adopt ASU No. 2018-15 effective September 30, 2018, on a prospective basis. The adoption 
of this guidance did not have a material impact on our consolidated financial statements.

Recently Issued Accounting Standards

In February 2016, the FASB issued ASU No. 2016-02 (Topic 842, “Leases”), as amended, which generally requires lessees to recognize 
operating and financing lease liabilities and corresponding right-of-use assets on the balance sheet and to provide enhanced disclosures surrounding 
the amount, time and uncertainty of cash flows arising from lease agreements. We expect to adopt this standard, on a modified retrospective basis, 
effective January 1, 2019 and will not restate comparative periods. 

With  respect  to  leases  in  which  we  are  the  lessee,  we  expect  to  recognize  a  lease  liability  and  a  corresponding  right-of-use  asset  of 
approximately $28.0 million on our consolidated balance sheet as of January 1, 2019. We will elect the package of practical expedients that allows 
us to not reassess: (1) whether any expired or existing contracts are or contain leases, (2) lease classification for any expired or existing leases and 
(3) initial direct costs for any expired or existing leases. As lessee, we have taken the accounting policy election to not recognize an asset and 
liability for leases with a term of 12 months or less. We will recognize lease payments in the Consolidated Statements of Operations on a straight-
line basis over the lease term.

Our drilling contracts contain a lease component related to the underlying drilling equipment, in addition to the service component provided 
by our crews and our expertise to operate such drilling equipment. We have concluded that the non-lease service of operating our equipment and 
providing expertise in the drilling of the client's well is predominant in our drilling contracts. We expect to apply the practical expedient to account 
for the lease and associated non-lease operations as a single component. With the election of the practical expedient, we will continue to present 
a single performance obligation under the new revenue guidance in ASC 606. 

We are currently finalizing our evaluation of what other effect, if any, ASC 842 will have on our consolidated financial statements and 
related disclosures. We do not expect our adoption to materially affect our Consolidated Balance Sheet, Consolidated Statement of Operations, or 
Consolidated Statement of Cash Flows.

In August 2018, the FASB issued ASU No. 2018-14, which amends 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 and is required to be adopted on a retrospective basis for all periods presented. We do not expect 
the adoption of this guidance to materially affect our consolidated financial 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— Consolidated Joint Ventures

We maintain a 50 percent interest in two joint ventures, each with a subsidiary of Royal Dutch Shell plc (“Shell”), that own and operate 
the two Bully-class drillships. We have determined that we are the primary beneficiary of the joint ventures. Accordingly, we consolidate the 
entities in our consolidated financial statements after eliminating intercompany transactions. Shell’s equity interests are presented as noncontrolling 
interests on our Consolidated Balance Sheets.

(Unless otherwise indicated, dollar amounts in tables are in thousands)

During the years ended December 31, 2018, 2017 and 2016, the Bully joint ventures approved and paid dividends totaling $55.2 million, 

$113.8 million and $171.9 million, respectively. Of these amounts, 50 percent was paid to our joint venture partner.

The combined carrying amount of the Bully-class drillships at December 31, 2018 and 2017 totaled $0.7 billion and $1.3 billion, respectively. 
These assets were primarily funded through partner equity contributions. During the year ended December 31, 2018, we recognized a $550.3 
million impairment on the Noble Bully I, of which $250.3 million is attributable to our joint venture partner. See “Note 6— Loss on Impairment” 
for  additional information. Cash  held by  the  Bully  joint ventures  totaled approximately $45.2  million  at  December 31,  2018  as  compared to 
approximately $41.6 million at December 31, 2017.

Only those items having a dilutive impact on our basic loss per share are included in diluted loss per share. For the years ended December 31, 
2018, 2017 and 2016, 12.5 million, 12.0 million and 9.9 million share-based awards, respectively, were excluded from the diluted loss per share 
since the effect would have been anti-dilutive. 

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. As of December 31, 2017, Paragon Offshore 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

Capital expenditures, including capitalized interest, totaled $281.3 million, $111.1 million and $659.9 million for the years ended 
December 31, 2018, 2017 and 2016, respectively. During the years ended December 31, 2018, 2017 and 2016, capitalized interest was $2.9 
million, zero and $22.4 million, respectively.

During the year ended December 31, 2017, we recognized a $14.3 million charge in “Contract drilling services” costs related to damages 

sustained on the Noble Danny Adkins and Noble Jim Day during Hurricane Harvey in the U.S. Gulf of Mexico region.

On September 21, 2018, we purchased the Noble Johnny Whitstine, a new GustoMSC CJ46 design jackup rig, from the PaxOcean Group 
(“PaxOcean”) in connection with a concurrently awarded drilling contract in the Middle East region. We paid $93.8 million for the rig, with $33.8 
million paid in cash and the remaining $60.0 million of the purchase price financed by the seller. See “Note 7— Debt” for additional information.

During the years ended December 31, 2018, 2017 and 2016, we recognized a non-cash loss on impairment of $802.1 million, $121.6 million 

and $1.5 billion, respectively, related to our long-lived assets. See “Note 6— Loss on Impairment” for additional information.

Note 6— Loss on Impairment 

Asset Impairments

In connection with the preparation of the consolidated financial statements included in this Annual Report, consistent with our accounting 
policies discussed in “Note 1— Organization and Significant Accounting Policies,” we evaluate our property and equipment for impairment 
whenever there are changes in facts which suggest that the value of the asset is not recoverable. In connection with the preparation of our financial 
statements for the year ended December 31, 2018, we conducted a review of our fleet. The review included an assessment of certain assumptions, 
including future marketability of each unit in light of its current technical specifications. Assumptions used in our assessment included, 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. 

During the years ended December 31, 2018, 2017, and 2016, we recognized a non-cash loss on impairment of $802.1 million, $121.6 million

and $1.5 billion, respectively, related to certain rigs and related capital spares.

Based upon our impairment analysis, we impaired the carrying values to estimated fair values for the Noble Bully I, Noble Dave Beard, 
Noble  Gene  House,  Noble  Joe  Beall,  Noble  Paul  Romano,  and  certain  capital  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 is attributable to our joint venture partner. See “Note 2— Consolidated Joint Ventures” for additional information.

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, and our belief that a drilling unit is no longer marketable and is unlikely to return to service. 
As a result, we determined that the carrying amounts of the Noble Amos Runner, Noble Alan Hay, Noble David Tinsley and certain capital spares 
were impaired and recorded an impairment charge of approximately $121.6 million.

During the year ended December 31, 2016, in connection with our impairment analysis, we impaired the carrying values to 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, and certain capital spare equipment would not be utilized 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.

Note 7— Debt 

Credit Facilities

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 is guaranteed by 
our indirect, wholly-owned subsidiaries, Noble Holding (U.S.) LLC (“NHUS”) and Noble Holding International Limited (“NHIL”) (the “2015 
Credit Facility”). At December 31, 2017, the 2015 Credit Facility also provided us with the ability to issue up to $500.0 million in letters of credit. 

On December 19, 2017, we entered into the First Amendment and Consent and Successor Agent Agreement (the “Amendment”) amending 
the 2015 Credit Facility. 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 termination 
of the 2015 Credit Facility's letter of credit sub-facility. The maturity of the 2015 Credit Facility remains January 2020. 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. At December 31, 2018, we had no borrowings outstanding or letters of credit issued under the 2015 Credit Facility.

2017 Credit Facility

On December 21, 2017, Noble Cayman Limited, a Cayman Islands company and a wholly-owned indirect subsidiary of Noble-Cayman 
(“NCL”); Noble International Finance Company, a Cayman Islands company and a wholly-owned indirect subsidiary of Noble-Cayman (“NIFCO”); 
and Noble Holding UK Limited, a company incorporated under the laws of England and Wales and a wholly-owned direct subsidiary of Noble-
UK (“NHUK”), as parent guarantor, entered into a new senior unsecured credit agreement (the “2017 Credit Facility” and, together with the 2015 
Credit Facility, the “Credit Facilities”). The maximum aggregate amount of commitments under the 2017 Credit Facility is approximately $1.5 
billion. 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. The 2017 Credit Facility will mature in January 2023. Borrowings may be used for working capital 
and other general corporate purposes. The 2017 Credit Facility provides for a letter of credit sub-facility currently in the amount of $15.0 million, 
with the ability to increase such amount up to $500.0 million with the approval of the lenders. At December 31, 2018, we had $3.4 million of 
performance letters of credit outstanding under the 2017 Credit Facility. At December 31, 2018, other than the performance letters of credit, we 
had no borrowings outstanding under the 2017 Credit Facility. 

Both of our Credit Facilities have provisions which vary the applicable interest rates for borrowings based upon our debt ratings. We also 
pay a facility fee under the 2015 Credit Facility on the full commitments thereunder (used or unused) and a commitment fee under the 2017 Credit 
Facility on the daily unused amount of the underlying commitments, in each case which varies depending on our credit ratings. At December 31, 
2018, the interest rates in effect under our Credit Facilities were the highest permitted interest rates under those agreements.

Debt Issuance

In January 2018, we issued $750.0 million aggregate principal amount of our Senior Notes due 2026 (the “2026 Notes”) through our indirect 
wholly-owned subsidiary, NHIL. The net proceeds of the offering of approximately $737.4 million, after expenses, were used to retire a portion 
of our near-term senior notes in a related tender offer.

The indenture for the 2026 Notes contains certain covenants and restrictions, including, among others, restrictions on our subsidiaries’ 
ability 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.

Seller Financing of Rigs

In September 2018, we purchased the Noble Johnny Whitstine for $93.8 million with a $60.0 million seller-financed secured loan (the 
“Seller Loan”). The Seller Loan has a term of four years and requires a 5% principal payment at the end of the third year with the remainder of 
the principal due at the end of the term. The Seller Loan bears 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 Seller Loan. Based on the terms of the Seller Loan, the 1.25% paid-in-kind interest rate is accelerated into the 
first year, resulting in an overall first year interest rate of 8.91%, of which only 4.25% is payable in cash. Thereafter, the paid-in-kind interest ends 
and the cash interest rate of 4.25% is payable for the remainder of the term. 

The Seller Loan is guaranteed by Noble-Cayman and is secured by a mortgage on the Noble Johnny Whitstine and by the pledge of the 
shares of the single-purpose entity that owns the rig. The Seller Loan contains debt to total capitalization ratio and minimum liquidity financial 
covenants substantially similar to the 2017 Credit Facility, and an asset and revenue covenant substantially similar to the 2026 Notes as well as 
other covenants and provisions customarily found in secured transactions. The Seller Loan requires immediate repayment on the occurrence of 
certain events, including the termination of the drilling contract entered into at the time of the purchase of the rig.

On February 14, 2019, we exercised our option to purchase a new jackup rig, to be known as the Noble Joe Knight, and we expect to 
complete the purchase in late February 2019. The purchase of the Noble Joe Knight will be partially funded with cash and seller loan on terms 
similar to the Noble Johnny Whitstine.

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 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 increased the interest rates on the 2025 Notes and the 2045 Notes to 7.95% and 8.95%, respectively, effective April 
2018. These senior notes have reached the contractually defined maximum interest rate set for each rating agency and no further interest rate 
increases are possible. The interest rates on these senior notes may be decreased if our debt ratings were to be raised by either rating agency above 
specified levels. Our other outstanding senior notes do not contain provisions varying applicable interest rates based upon our credit ratings.

Debt Tender Offers, Repayments and Open Market Repurchases

In January 2018, we commenced cash tender offers for the 2018 Notes, our Senior Notes due 2019 (the “2019 Notes”), our Senior Notes 
due 2020, our Senior Notes due 2021, our Senior Notes due 2022 and our Senior Notes due 2024. 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 and 
cash on hand. As a result of this transaction, we recognized a net loss of approximately $3.5 million.

In February 2018, we redeemed the remaining principal amount of $61.9 million of the 2019 Notes for approximately $65.3 million, plus 

accrued interest. As a result of this transaction, we recognized a net loss of approximately $3.5 million.

In March 2018, we repaid the remaining aggregate principal amount of $126.6 million of the 2018 Notes at maturity using cash on hand.

In March 2018, we purchased $9.5 million aggregate principal amount of various tranches of our senior notes for approximately $8.7 

million, plus accrued interest, as open market repurchases and recognized a net gain of approximately $0.5 million.

In August 2018, we purchased $0.4 million aggregate principal amount of our Senior Notes due 2042 for approximately $0.3 million, plus 

accrued interest, as open market repurchases and recognized a net gain of approximately $0.1 million.

In October 2018, we purchased $27.4 million aggregate principal amount of various tranches of our senior notes for approximately $20.2 

million, plus accrued interest, as open market repurchases and recognized a net gain of approximately $6.9 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 the end of each fiscal quarter.

The 2017 Credit Facility contains certain financial covenants applicable to NHUK and its subsidiaries, including (i) a covenant restricting 
debt to total tangible capitalization to not greater than 0.55 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 (as defined in the 2017 Credit Facility) 
of Marketed Rigs (as defined in the 2017 Credit Facility) to the sum of commitments under the 2017 Credit Facility 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 

72

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Unless otherwise indicated, dollar amounts in tables are in thousands)

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 (as 
defined in the 2017 Credit Facility) that are directly wholly owned by the borrowers and guarantors to (B) the Rig Value of the Closing Date Rigs 
owned by 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. In addition, on January 19, 2018, certain indirect 
subsidiaries of Noble-UK became guarantors under the 2017 Credit Facility, including Noble Dave Beard Limited, Noble Drilling (TVL) Ltd., 
Noble Resources Limited, Noble SA Limited, Noble BD LLC, Noble Drilling Holding LLC, Noble Drilling International GmbH, Noble Leasing 
(Switzerland) GmbH, and Noble Leasing III (Switzerland) GmbH. Certain other subsidiaries of Noble-UK may be required from time to time to 
guarantee the obligations of the borrowers under the 2017 Credit Facility in order maintain compliance with the Guarantor Ratio Covenants.

The 2017 Credit Facility contains additional restrictive covenants generally applicable to NHUK and its subsidiaries, including 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 of the 2017 Credit Facility, sale and leaseback transactions and transactions with affiliates.

In addition to the covenants from the Credit Facilities noted above, the covenants from the 2026 Notes described under “—Debt Issuance” 
above, and the covenant from the Seller Loan described under “—Seller Financing of Rig” above, the indentures governing our outstanding senior 
unsecured notes contain covenants that place restrictions on certain merger and consolidation transactions, unless we are the surviving entity or 
the other party assumes the obligations under the indenture, and on the ability to sell or transfer all or substantially all of our assets. There are also 
restrictions on incurring or assuming certain liens and on entering into sale and lease-back transactions.

At December 31, 2018, our debt to total tangible capitalization ratio under our 2017 Credit Facility was approximately 0.48 and we were 
in compliance with all applicable debt covenants. We continually monitor compliance with the covenants under our Credit Facilities, senior notes 
and Seller Loan and expect to remain in compliance throughout 2019.

Fair Value of Debt

Fair value represents the amount at which an instrument could be exchanged in a current transaction between willing parties. The estimated 
fair value of our debt instruments was based on the quoted market prices for similar issues or on the current rates offered to us for debt of similar 
remaining maturities (Level 2 measurement). All remaining fair value disclosures are presented in “Note 14— Fair Value of Financial Instruments.”

As of December 31, 2018, Noble-UK had approximately 246.8 million shares outstanding and trading as compared to approximately 245.0 
million shares outstanding and trading at December 31, 2017. At our 2018 Annual General Meeting, shareholders approved a proposal to allow 
our Board of Directors to increase share capital through the issuance of up to 82.2 million ordinary shares (at current nominal value of $0.01 per 
share) The right of our directors to allot shares will expire at the end of our 2019 Annual General Meeting unless we seek an extension from 
shareholders at that time. No shares were allotted during the year ended December 31, 2018.

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 law. 
Therefore, Noble-UK is not permitted to pay dividends out of share capital, which includes share premium. Noble has 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.

Share Repurchases

Under UK law, the Company is only permitted to purchase its own shares by way of an “off-market purchase” in a plan approved by 
shareholders. We currently do not have shareholder authority to repurchase shares. During the years ended December 31, 2018, 2017 and 2016, 
we did not repurchase any of our shares.

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 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 2015 Incentive Plan. 
Neither consultants nor non-employee directors are eligible for awards under the 2015 Incentive Plan.

During 2018, 2017 and 2016, the 2015 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 2015 Incentive Plan by 5.0 million, 3.7 million and 9.5 
million shares, respectively. The maximum aggregate number of ordinary shares that may be granted for any and all awards under the 2015 
Incentive  Plan  will  not  exceed  25.5  million  shares  and  at  December 31,  2018,  we  had  11.5  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. During 2017, upon shareholder approval, the Noble Corporation plc 2017 Director 
Omnibus Plan (the “Director Plan”) replaced the 1992 Plan. At the same time, the 1992 Plan was terminated and equity based awards to non-
employee directors are now made only through the Director Plan.

Stock Options

Options have a term of 10 years, an exercise price equal to the fair market value of a share on the date of grant and generally vest over a 
three-year period. A summary of the status of stock options granted under both the 1991 Plan and 1992 Plan as of December 31, 2018, 2017 and 
2016 and the changes during the year ended on those dates is presented below:

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. Treasury yield curve in effect at the time of grant.

There were no non-vested stock option balances at December 31, 2018 or any changes during the year ended December 31, 2018. No new 

stock options were granted during the years ended December 31, 2018, 2017 and 2016.

There was no compensation cost recognized during the years ended December 31, 2018, 2017 and 2016, respectively, related to stock 

options. 

Restricted Stock Units (“RSUs”)

We have awarded both Time Vested RSUs (“TVRSUs”) and Performance Vested (“PVRSUs”) under the 1991 Plan and the 2015 Incentive 
Plan. The TVRSUs generally vest over a three-year period. The number of PVRSUs which vest will depend on the degree of achievement of 
specified corporate performance criteria over a three-year performance period. Depending on the date the PVRSU was awarded, these criteria 
consist of market based criteria or market and performance based criteria.

The TVRSUs are valued on the date of award at our underlying share price. The total compensation for units that ultimately vest is recognized 
over the service period. The shares and related nominal value are recorded when the restricted stock unit vests and additional paid-in capital is 
adjusted as the share-based compensation cost is recognized for financial reporting purposes.

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:

Valuation assumptions:
Expected volatility
Expected dividend yield
Risk-free interest rate

The number of PVRSUs shown equals the units that would vest if the “maximum” level of performance is achieved. The minimum 

number of units is zero and the “target” level of performance is 50 percent of the amounts shown.

At December 31, 2018, there was $15.8 million of total unrecognized compensation cost related to the TVRSUs, which is expected to be 
recognized over a remaining weighted-average period of 1.6 years. The total award-date fair value of TVRSUs vested during the year ended 
December 31, 2018 was $20.3 million.

At December 31, 2018, there was $6.7 million of total unrecognized compensation cost related to the PVRSUs, which is expected to be 
recognized over a remaining weighted-average period of 1.1 years. The total potential compensation for PVRSUs is recognized over the service 
period  regardless  of  whether  the  performance  thresholds  are  ultimately  achieved.  In  February  2019,  1,450,802  PVRSUs  for  the  2016-2018

respectively.  During  the  years  ended  December 31,  2018  and  2017,  capitalized  share-based  amortization  was  zero.  During  the  year  ended

Defined benefit pension items relate to actuarial changes and the amortization of prior service costs. Reclassifications from AOCI are 
recognized  as  expense  on  our  Consolidated  Statements  of  Operations  through  either  “Contract  drilling  services”  or  “General  and

Accounts  receivable  are  recognized  when  the  right  to  consideration  becomes  unconditional  based  upon  contractual  billing  schedules. 
Payment terms on invoiced amounts are typically 30 days. Current contract asset and liability balances are included in “Prepaid expenses and 
other current assets” and “Other current liabilities,” respectively, and noncurrent contract assets and liabilities are included in “Other assets” and 
“Other liabilities,” respectively, on our Consolidated Balance Sheets.

We have elected, as a practical expedient, not to disclose significant changes in the remaining performance obligation for the year ended 

December 31, 2017, which was before our adoption date of January 1, 2018.

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.

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, 2018. 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.

Our revenue recognition pattern under ASC 606 is materially equivalent to revenue recognition under the previous guidance. For the year 
ended  December 31,  2018,  there  were  no  material  effects  to  our  Consolidated  Balance  Sheets,  Consolidated  Statements  of  Operations,  or 
Consolidated Statements of Cash Flows.

Noble-UK is a company which is a tax resident in the UK and, as such, will be 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 exemptions 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.

On December 22, 2017, the President of the United States signed the Act into law. The Act makes significant changes to various areas of 
U.S. federal income tax law by, among other things, lowering corporate income tax rates, implementing the territorial tax system, and rules limiting 
base erosion, and imposing a repatriation tax on deemed repatriated earnings of foreign subsidiaries of U.S parent shareholders.

During the fourth quarter of 2017, the Act resulted in the write-down of our U.S. net deferred tax liabilities. In accordance with the guidance 
issued in SAB No. 118, during the third quarter of 2018, we finalized our provisional amounts recorded as we completed our technical analysis, 
computations and tax law interpretations and filed our 2017 U.S. tax return. As a result, we recognized an additional tax benefit of $24.9 million.

The Company has considered new provisions of The Act that became effective in 2018. Two such provisions, which had an impact on the 

Company’s financial results for the current period, are as follows:

• 

• 

The Act limits the deduction of interest paid or accrued on indebtedness. This limitation results in a deferral for U.S. federal 
income tax purposes and requires the recording of a deferred tax asset for the benefit of the interest deduction carryforward. 
The interest deduction carryforward has an indefinite life.
The Act eliminates the U.S. federal income tax carryback provision for net operating losses (“NOLs”) and limits the taxpayer’s 
ability to utilize NOL carryforwards to 80 percent of taxable income. The NOL carryforward has an indefinite life.

The Act also 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, of its foreign subsidiaries. The Company has adopted a policy to treat tax due on future U.S. inclusions 
in taxable income as period costs when incurred.

The Company continues to monitor developments in regulations.

At December 31, 2018, the reserves for uncertain tax positions totaled $183.8 million (net of related tax benefits of 1.0 million). If a portion 
or all of the December 31, 2018 reserves are not realized, the provision for income taxes could be reduced by up to $183.8 million. At December 31, 
2017, the reserves for uncertain tax positions totaled $191.9 million (net of related tax benefits of 1.0 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 reasonably estimate a range of 
changes in our existing liabilities due to various uncertainties, such as the unresolved nature of various audits.

We include, as a component of our “Income tax provision,” potential interest and penalties related to recognized tax contingencies within 
our global operations. Interest and penalties resulted in an income tax expense of $5.1 million in 2018, an income tax expense of $4.7 million in 
2017 and an income tax benefit of $2.7 million in 2016.

During the year ended December 31, 2018, our income tax provision included non-cash items of $35.6 million related to the impairment 

of three rigs and certain capital spares. See “Note 6— Loss on Impairment” for additional information.

We conduct business globally and, as a result, we file numerous income tax returns in U.S. and in non-U.S. jurisdictions. In the normal 
course of business we are subject to examination by taxing authorities throughout the world, including in jurisdictions such as Brazil, Brunei, 
Bulgaria, Canada, Cyprus, Egypt, Hungary, Malta, Mexico, Nigeria, Norway, Saudi Arabia, Argentina, Australia, Denmark, Gabon, Luxembourg, 
Malaysia, the Netherlands, Oman, Qatar, Tanzania, Singapore, Suriname, Switzerland, the United Kingdom and the United States. We are no 
longer subject to U.S. Federal income tax examinations for years before 2010 and non-U.S. income tax examinations for years before 2000.

Due to foreign tax credit limitation constraints, in 2018, 2017 and 2016, the Company has made the determination to take foreign tax 

expense as a deduction against U.S. taxable income.

At December 31, 2018, the Company asserted that the investment in foreign subsidiaries is permanent in nature, and estimated that there 

are no net cumulative earnings in its foreign subsidiaries.

For interim and annual reporting periods beginning after December 15, 2017, ASU No. 2016-16 will be applied on a modified retrospective 
basis to improve the accounting for the income tax consequences of intra-entity transfers of assets other than inventory. As the result of the 
application of this standard, we recorded deferred charges of $148.4 million in to “Retained earnings” on our Consolidated Balance Sheets.

During the fourth quarter of 2017, the Act resulted in the write-down of our U.S. net deferred tax liabilities. In accordance with the guidance 
issued in SAB No. 118, during the third quarter of 2018, we finalized our provisional amounts recorded as we completed our technical analysis, 
computations and tax law interpretations and filed our 2017 U.S. tax return. As a result, we recognized an additional tax benefit of $24.9 million.

Note 12— Employee Benefit Plans

Defined Benefit Plans

Noble Drilling (Land Support) Limited, an indirect, wholly-owned subsidiary of Noble-UK (“NDLS”), 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 (referred to as our “non-U.S. plan”).

In addition to the non-U.S. plan discussed above, we have a U.S. noncontributory defined benefit pension plan that covers certain salaried 
employees and a U.S. 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.  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 credits available to us, for the qualified U.S. plans when required. The benefit amount that can be covered by the qualified U.S. plans is 
limited under ERISA and the Internal Revenue Code 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 salaried U.S. plan. We refer to the qualified U.S. plans and the 
excess benefit plan collectively as the “U.S. plans.”

During the fourth quarter of 2016, we approved amendments, effective as of December 31, 2016, to our non-U.S. and U.S. 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.

There is less than $0.1 million and $2.8 million estimated net actuarial losses and prior service costs for the non-U.S. plan and the U.S. 

plans, respectively, that will be amortized from AOCI into net periodic pension cost in 2019.

During the years ended December 31, 2018, 2017 and 2016, 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 2018, 2017 and 2016 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. plans by approximately $0.6 million, $1.6 million and 
$2.9 million as of December 31, 2018, 2017 and 2016.

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-U.S. plan, and the impact is included as a prior service cost as of December 31, 2018, which will be 
amortized over the average life expectancy of the members at that date.

The discount rates used to calculate the net present value of future benefit obligations for our U.S. plans is based on the average of current 
rates earned on long-term bonds that receive a Moody’s rating of “Aa” or better. We have determined that the timing and amount of expected cash 
outflows on our plans reasonably match this index. For our non-U.S. plan, the discount rate used to calculate the net present value of future benefit 
obligations is 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. and non-U.S. plans that use a portfolio return model. 

Defined Benefit Plans—Plan Assets

Non-U.S. Plan

The NDLS pension Scheme targets an asset allocation of 48.0% return-seeking securities (Growth) and 52.0% debt securities (Matching). 
The trustees have decided to implement a de-risking strategy whereby the level of investment risk reduces as the Scheme’s funding level improves. 
The overall investment objective of the Scheme, as adopted by the Scheme’s Trustees, is to reach a fully funded position on the agreed de-risking 
basis of Gilts - 0.45% per annum. The objectives within the Scheme’s overall investment strategy is to outperform the cash + 4% per annum long 
term objective for Growth assets and to sufficiently hedge interest rate and inflation risk within the Matching portfolio in relation to the Scheme’s 
liabilities. By achieving these objectives, the Trustees believe the Scheme will be able to avoid significant volatility in the contribution rate and 
provide sufficient assets to cover the Scheme’s benefit obligations. To achieve this the Trustees have given Mercer, the appointed investment 
manager, full discretion in the day-to-day management of the Scheme’s assets and implementation of the de-risking strategy, who in turn invests 
in multiple underlying investment managers where appropriate. The Trustees meet with Mercer periodically to review and discuss their investment 
performance.

The fundamental objective of the 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 approximately 31.5% equity securities, 67.3% fixed income securities, and 1.2% in cash and equivalents. 

87

 
 
NOBLE CORPORATION PLC AND SUBSIDIARIES
NOBLE CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Unless otherwise indicated, dollar amounts in tables are in thousands)

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 three to five year time period). Actual 
allocations 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.

For investments in mutual funds, the assets of the Trust are subject to the guidelines and limits imposed by such mutual fund’s prospectus 

and the other governing documentation at the fund level.

As of December 31, 2018, no single security made up more than 10 percent of total assets of either the U.S. or the non-U.S. plans.

Defined Benefit Plans—Cash Flows

In 2018, we made no contributions to our non-U.S. plan and contributions of $4.6 million to our U.S. plans. In 2017, we made total 
contributions of $0.7 million and $2.3 million to our non-U.S. and U.S. plans, respectively. In 2016, we made total contributions of $2.8 million
and $0.4 million to our non-U.S. and U.S. plans, respectively. We expect our aggregate minimum contributions to our non-U.S. and U.S. plans in 
2019, subject to applicable law, to be zero and $1.1 million, respectively. We continue to monitor and evaluate funding options based upon market 
conditions and may increase contributions at our discretion.

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, 2018 and 2017, our liability for the 401(k) Restoration Plan was $8.2 million and $8.8 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 
in the plan. Participants in the plan become fully vested in the plan after three years of service. 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 $2.3 million, $3.1 million
and $6.0 million, respectively, for three years ended December 31, 2018, 2017 and 2016.

We sponsor other retirement, health and welfare plans and a 401(k) savings plan for the benefit of our employees. The cost of maintaining 
these plans for continuing operations aggregated approximately $25.0 million, $27.6 million and $37.2 million in 2018, 2017 and 2016, respectively. 
We do not provide post-retirement benefits (other than pensions) or any post-employment benefits to our employees.

Note 13— Derivative Instruments and Hedging Activities 

We periodically enter into derivative instruments to manage our exposure to fluctuations in interest rates and foreign currency exchange 
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 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 have historically settled monthly in the operations’ 
respective  local  currencies. All  of  these  contracts  had  a  maturity  of  less  than  12  months. There  were  no  foreign  currency  forward  contracts 
outstanding or entered into during the year ended December 31, 2018.

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 table.

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.

Note 15— Commitments and Contingencies

Transocean Ltd. 

In January 2017, a subsidiary of Transocean Ltd. (“Transocean”) filed suit against us and certain of our subsidiaries for patent infringement 
in a Texas federal court. The suit claims that five of our newbuild rigs that operated in the U.S. Gulf of Mexico violated Transocean patents relating 
to what is generally referred to as dual-activity drilling. We were aware of the patents when we constructed the rigs. The patents are now expired 
in the United States and most other countries. While there is inherent risk in litigation, we do not believe that our rigs infringe the Transocean 
patents. Transocean also recently added another claim alleging that we breached a 2007 settlement agreement we entered into with Transocean 
relating to patent claims in respect of another Noble rig. We also do not believe there has been any breach of the 2007 agreement. The litigation 
continues, and we believe the court could set a trial date for the third quarter of 2019. We continue to defend ourselves vigorously against this 
claim.

Brazil commercial agent 

We previously used a commercial agent in Brazil in connection with our Petróleo Brasileiro S.A. (“Petrobras”) drilling contracts. This agent 
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 was substantially completed in 2017, of our relationship with the agent 
and with Petrobras. We have been in contact and cooperated with the SEC, the Brazilian federal prosecutor’s office and the U.S. Department of 
Justice (“DOJ”) about this matter, and in December 2018, the SEC and the DOJ each advised us that they had closed their file on this matter. We 
have remained in contact with the Brazilian federal prosecutor’s office, who is aware of our internal review, and continue to cooperate with any 
questions or requests they may have. 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.

Paragon Offshore

  On August 1, 2014, Noble-UK 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 Noble’s ordinary shares. In 
February 2016, Paragon Offshore sought approval of a pre-negotiated plan of reorganization (the “Prior Plan”) by filing for voluntary relief under 
Chapter 11 of the United States Bankruptcy Code. As part of the Prior Plan, we entered into a settlement agreement with Paragon Offshore (the 
“Settlement Agreement”). The Prior Plan was rejected by the bankruptcy court in October 2016.

  In April 2017, Paragon Offshore filed a revised plan of reorganization (the “New Plan”) in its bankruptcy proceeding. Under the New 
Plan, Paragon Offshore no longer need the Mexican tax bonding that Noble-UK was to provide under the Settlement Agreement. 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 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. The complaint states that the litigation 
trust is seeking damages of approximately $1.7 billion from the Company, an amount equal to the amount borrowed by Paragon Offshore immediately 
prior  to  the  Spin-off,  as  well  as  unspecified  amounts  in  respect  of  the  claims  against  the  officer  and  director  defendants,  all  of  whom  have 
indemnification agreements with us. We requested that the court dismiss the claims of breach of fiduciary duty, aiding and abetting breach of 
fiduciary duty and unjust enrichment, and require such claims to be arbitrated under the MSA entered into between Noble and Paragon Offshore 
at the time of the Spin-off, as well as stay the other proceedings during the pendency of the arbitration. The court ruled that the unjust enrichment 
claim be arbitrated and that the other claims proceed in bankruptcy court. We and the litigation trust have mutually agreed to drop our respective 
appeals of the arbitration ruling and now all matters will be heard in court, which will streamline the case. Discovery continues and the court has 
approved a litigation schedule, which could result in all pre-trial activity being completed by the end of 2019. A trial date has not yet been set.

We believe that Paragon Offshore, at the time of the Spin-off, was properly funded, solvent and had appropriate liquidity and that the claims 
brought by the litigation trust are without merit. We intend to defend ourselves vigorously. However, there is inherent risk and substantial expense 
in litigation, and the amount of damages the plaintiff is seeking is substantial. If any of the litigation trust’s claims are successful, or if we elect

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Unless otherwise indicated, dollar amounts in tables are in thousands)

to settle any claims (in part to reduce or eliminate the ongoing cost of defending the litigation and eliminate any risk of a larger judgment against 
us), 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. Because of our view of the merits of the claims and the significant discovery still to be conducted in the litigation, we 
are not currently able to make a reasonable estimation of the amount of possible loss we may incur, if any. Subsequent developments in the litigation 
may make such an estimation possible, in which case we may record a charge against our income when a loss is reasonably estimable. This may 
occur even though the litigation may still be ongoing. Any charge could be material and could have a material adverse effect on our financial 
condition and results of operations. It may also be materially different than any amount we are required to pay once the litigation is concluded. 

We have directors’ and officers’ indemnification coverage for the officers and directors who have been sued by the litigation trust. The 
insurers have accepted coverage for the director and officer claims and we are continuing to discuss with them the scope of their reimbursement 
of litigation expenses. In addition, at the time of the Spin-off, we had entity coverage, or “Side C” coverage, which was meant to cover certain 
litigation claims up to the coverage limit of $150.0 million, including litigation expenses. We have made a claim for coverage of the litigation 
trust’s claims against Noble under such entity insurance. The insurers have rejected coverage for these claims. We cannot predict the amount of 
claims and expenses we may incur, pay or settle in the Paragon Offshore litigation that such insurance will cover, if any.

Prior 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 Agreements 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.

The rejection and ultimate termination of the indemnity and related obligations under the Separation Agreements resulted in a number of 
accounting charges and benefits during 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.”

Tax matters

During 2014, the Internal Revenue Service (“IRS”) began its examination of our tax reporting in the U.S. for the taxable years ended 
December 31, 2010 and 2011. The IRS examination team has completed its examination of our 2010 and 2011 U.S. tax returns and proposed 
adjustments and deficiencies with respect to certain items that were reported by us for the 2010 and 2011 tax year. On December 19, 2016, we 
received the Revenue Agent Report from the IRS. We believe that we have accurately reported all amounts in our tax returns, and have submitted 
administrative protests with the IRS Office of Appeals contesting the examination team’s proposed adjustments. We intend to vigorously defend 
our reported positions, and believe the ultimate resolution of the adjustments proposed by the IRS examination team 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.

Audit claims of approximately $50.7 million attributable to income and other business taxes were assessed against Noble entities in Mexico 
related to tax years 2005 and 2007. We intend to vigorously defend our reported positions, and believe the ultimate resolution of the audit claims 
will not have a material adverse effect on our consolidated financial statements.

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. We cannot predict or provide assurance as to the ultimate outcome of any existing or future assessments.

Other contingencies 

We have entered into agreements with certain of our executive officers, as well as certain other employees. These agreements become 
effective upon a change of control of Noble-UK (within the meaning set forth in the agreements) or a termination of employment in connection 
with or in anticipation of a change of control, and remain effective for three years thereafter. These agreements provide for compensation and 
certain other benefits under such circumstances.

We are a defendant in certain claims and litigation arising out of operations in the ordinary course of business, including personal injury 
claims, the resolution of which, in the opinion of management, will not be material to our financial position, results of operations or cash flows. 
There is inherent risk in any litigation or dispute and no assurance can be given as to the outcome of these claims.

We lease certain office space and warehouse facilities under cancelable and non-cancelable leases. Rent expense under these arrangements 

totaled $7.5 million, $8.3 million and $7.8 million for the years ended December 31, 2018, 2017 and 2016, respectively.

In February 2019, we amended the lease of our Sugar Land office to extend the lease for an additional ten years and to reduce the rented 
space. The above table does not include this lease amendment. 

Note 16— Segment and Related Information 

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 December 31, 2018, our contract drilling services segment conducts 
contract drilling operations in Canada, Far East Asia, the Middle East, the North Sea, Oceania, the Black Sea, South America and the U.S. Gulf 
of Mexico.

In accordance with our adoption of ASU No. 2016-09, prior period excess tax benefits, which were previously classified as a 
financing activity in “Employee stock transactions,” are now classified as an operating activity in “Net change in other assets and liabilities” 
on our Consolidated Statement of Cash Flows and current period excess tax benefits are now recognized in our Consolidated Statement 
of  Operations  through  income  taxes. Additionally,  shares  withheld  for  taxes  on  employee  stock  transactions,  which  were  previously 
classified as an operating activity in “Net change in other assets and liabilities,” are now classified as a financing activity in “Employee 
stock transactions” on our Consolidated Statement of Cash Flows.

Revision of Prior Period Financial Statements

During the preparation of our 2018 financial statements, we identified a computational error that resulted in misstatements of certain 
line items on the Consolidated Statements of Cash Flows for Noble Corporation plc and Noble Corporation (Cayman) for the years ended 
December 31,  2017  and  2016. These  errors  did  not  impact  our  cash,  cash  equivalents  and  restricted  cash  balances. We  assessed  the 
materiality of the misstatements and concluded the misstatements were immaterial to the previously issued financial statements.

We have revised the Consolidated Statements of Cash Flows for the years ended December 31, 2017 and 2016. The impacts on the 

Consolidated Statements of Cash Flows and related notes to the financial statements are presented below:

Revision of Prior Period Financial Statements

During the preparation of our 2018 financial statements, we identified a computational error that resulted in misstatements of certain line 
items on the Consolidated Statements of Cash Flows for Noble Corporation (Cayman) for the years ended December 31, 2017 and 2016. These 
errors did not impact our cash, cash equivalents and restricted cash balances. We assessed the materiality of the misstatements and concluded the 
misstatements were immaterial to the previously issued financial statements. 

We have revised the Consolidated Statements of Cash Flows for the years ended December 31, 2017 and 2016.   The impacts on the 

Consolidated Statements of Cash Flows and related notes to the financial statements are presented below:

Item 9A. Evaluation of Disclosure Controls and Procedures

Julie J. Robertson, Chairman, President and Chief Executive Officer of Noble-UK, and Adam C. Peakes, Senior Vice President and Chief 
Financial Officer of Noble-UK, have evaluated the disclosure controls and procedures of Noble-UK as of the end of the period covered by this 
report. On the basis of this evaluation, Ms. Robertson and Mr. Peakes have concluded that Noble-UK’s disclosure controls and procedures were 
effective as of December 31, 2018. Noble-UK’s disclosure controls and procedures are designed to ensure that information required to be disclosed 
by Noble-UK in the reports that it files with or submits to the SEC are recorded, processed, summarized and reported within the time periods 
specified in the SEC’s rules and forms and is accumulated and communicated to management as appropriate to allow timely decisions regarding 
required disclosure.

Julie J. Robertson, President and Chief Executive Officer of Noble-Cayman, and Adam C. Peakes, Director, Vice President and Chief 
Financial Officer of Noble-Cayman, have evaluated the disclosure controls and procedures of Noble-Cayman as of the end of the period covered 
by  this  report.  On  the  basis  of  this  evaluation,  Ms.  Robertson  and  Mr.  Peakes  have  concluded  that  Noble-Cayman’s  disclosure  controls  and 
procedures were effective as of December 31, 2018. Noble-Cayman’s disclosure controls and procedures are designed to ensure that information 
required to be disclosed by Noble-Cayman in the reports that it files with or submits to the SEC are recorded, processed, summarized and reported 
within the time periods specified in the SEC’s rules and forms and is accumulated and communicated to management as appropriate to allow 
timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting

There were no changes in either Noble-UK’s or Noble-Cayman’s internal control over financial reporting that occurred during the year 
ended December 31, 2018 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.

Management’s Annual Report on Internal Control Over Financial Reporting

The management of Noble-UK and Noble-Cayman 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. 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-Cayman maintained effective internal control over financial reporting 
as of December 31, 2018.

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, 2018 as stated in their 
report, which is provided in Part II, Item 8, “Financial Statements and Supplementary Data” in this Annual Report on Form 10-K.
