BETTER  is more than a word, it’s a mindset. It defines what’s possible and challenges 

us to consider new ideas. Better is potential not yet realized and opportunity waiting 

to be seized. Better is what keeps us focused on the big picture and helps us prepare 

for what’s next. Better is what drives us to dig deeper and try harder, always working 

to add value, always striving to improve. AT CONCHO, better is a fundamental 

component in our pursuit of excellence. It defines our culture. It focuses our trajectory. 

It sets us apart. It’s why we’re at the forefront of applying advanced technology and 

large-scale development to safely and efficiently maximize resource recovery, while 

delivering attractive, long-term economic returns in the Permian Basin. It’s also why 

we strive to create a diverse and engaging workplace and provide every employee  

with opportunities for professional and personal growth. EVERY DAY  we work 

to  deliver  a  better  tomorrow  for  our  shareholders,  our  team  and  the  communities 

where we live and work.

D E A R   S H A R E H O L D E R S ,

Dear Shareholders,

For the first time in 75 years, the United States became 
a net exporter of crude oil and fuel. The nation’s energy 
self-sufficiency is the result of shale production setting 
new records. In fact, the U.S. is now the world’s largest 
oil producer, surpassing both Russia and Saudi Arabia 
in late 2018. As you know from my letters by now, the 
domestic  oil  growth  phenomenon  is  a  result  of  the 
industry’s  commitment  to  efficiently  developing  one 
of the largest, most secure resources in the world: the 
Permian Basin.

Permian activity is nearly back to the peak level reached in 2014 
just  before  OPEC’s  decision  to  continue  pumping  into  a  then-
oversupplied market — a decision that pushed oil prices lower for 
longer.  Since  then,  the  cyclical  nature  of  our  business  has  been 
apparent. In 2018, the average price for oil was almost 30% higher 
than in 2017. However, the average price doesn’t tell the whole 
story and disguises the 44% drop in oil prices experienced in the 
last two months of the year.

Our goal is to deliver superior growth and returns for our shareholders 
in any environment. The steadfast execution of our strategy — with a 
focus on our team, assets, returns and financial strength — continues 
to  position  us  well  to  deliver  on  this  goal.  During  2018,  while 
running one of the largest development programs in the Permian, 
we also achieved solid results and took meaningful steps to allow 
for Concho’s continued growth and prosperity. 

In  a  year  of  many  accomplishments,  our  biggest  milestone  was 
acquiring RSP Permian. The acquisition builds on our track record 
of  carefully  and  strategically  consolidating  the  best  parts  of  the 
Permian  Basin.  Importantly,  we’ve  incorporated  RSP’s  premium 
resource into our development program with large-scale, multi-well 
projects that generate solid, highly economic growth. Today, our 
position spans nearly one million gross acres and is a competitive 
advantage  that  provides  strength  across  the  cycles.  And  we’re 
continuously  working  to  optimize  our  acreage  through  trades 
and non-core asset sales. During 2018, we executed asset trades 
covering 60 thousand net acres in aggregate, and since 2016, we’ve 
divested non-core assets for $1.5 billion in proceeds.

Our development activities and the RSP acquisition drove a 36% 
increase in production and significant resource expansion in 2018. 
During 2018, we generated operating cash flow of approximately  
$2.6 billion, exceeding our capital investment for exploration and 
development activities. This represents the third consecutive year 
our operating cash flow exceeded cash used in investing activities 
for  exploration  and  development,  underscoring  our  disciplined 
approach to capital allocation and asset quality. We ended the year 
with a strong balance sheet and investment-grade credit ratings 
from the top three ratings agencies. 

There’s growth for the sake of growth, and then there’s value-driven 
growth. From the beginning, we’ve worked hard to ensure that we 
deliver the latter. We believe our performance over our first decade 
as a public company secures us well as we enter the next stage of our 
company, which includes the right combination of competitive and 
sustainable growth of oil production and free cash flow. Available 
cash flow will provide us the flexibility to make additional returns 
to shareholders and reinforce our balance sheet. It will also open 
opportunities for ongoing growth and value creation. Ultimately, we 
are a growth company, and we believe our platform for delivering 
a successful, long-term investment has never been better.

Our achievements could not be possible without the dedication 
and hard work from our team. They are our biggest competitive 
advantage, and this year our team was bolstered by the addition of 
our new colleagues from RSP. Led by a management team that has 
been carefully cultivated over the last decade, Concho’s employees 
go above and beyond to produce the safest, most efficient barrel. 
We are committed to investing in our people, as we know that they 
are the reason our future is bright. 

I would also like to use this opportunity to remember our friend, 
colleague and member of our Board of Directors, Ray Poage, who 
passed away in February 2019. Ray first joined the Concho Board as 
we prepared for our IPO in 2007, and he was always optimistic and 
excited about Concho’s future. It was a privilege to have worked 
alongside him for so many great years. 

I also want to thank our shareholders for your continued support. 
Your  investment  is  what  has  allowed  us  to  continuously  move 
forward, enabling us to get better. From going public in 2007 to 
completing our largest acquisition yet in 2018, we have a lot to be 
proud of and plan to further our track record of leading the way 
in the Permian Basin.

Sincerely,

TIM LEACH 

Chairman of the Board and Chief Executive Officer

Better Begins with
Premier Assets

Our  unique  portfolio  provides  us  with  a  competitive 
advantage, and we take pride in the premier asset base 
we have built. Owning large, concentrated positions in 
the Permian Basin enables Concho to capitalize on the 
technological and economic advantages of scale. With 
ongoing development success, the breadth and depth 
of our inventory allows us to navigate commodity price 
cycles and deliver peer-leading economic returns. 

Throughout 2018 we extended our track record of consolidating 
high-quality  acreage  to  block  up  for  long-lateral  and  multi-well 
project development. We completed the acquisition of RSP Permian, 
the  largest  acquisition  in  our  company’s  history.  The  transaction 
enhanced  our  long-term  strategy  and  the  scale  of  our  growth 
platform. During the year, we also executed 15 asset trades, covering 
60 thousand aggregate net acres.

We also divested non-core assets for proceeds of $361 million and 
received an approximately $160 million cash distribution from our 
investment in the Oryx regional gathering system. Proceeds from 
non-core asset sales completed during 2016 through 2018 totaled 
$1.5 billion. Returns-focused development, acquisitions and trades 
are integral to scalable growth in the Permian.

Better Begins with
Operating Excellence

The Permian Basin is one of the largest, most secure 
deposits  of  oil  in  the  world,  and  has  been  Concho’s 
home for more than 10 years. The Permian Basin is not 
only  where  our  employees  live  and  work,  but  where 
we continually invest for the future. As competition to 
supply the most efficient barrel intensifies, technology 
is increasingly important.

The Shale Revolution has passed through three stages: discovery, 
delineation and now development. Today we are in manufacturing 
mode, which means developing reserves with large-scale, multi-zone 
projects.  This  style  of  development  is  important  for  maximizing 
recoveries, achieving economies of scale and delivering long-term 
economic returns. 

During the year we safely and efficiently executed one of the largest 
drilling  programs  in  the  Permian  Basin.  We  advanced  large-scale 
development  across  our  portfolio  and  allocated  more  capital  to 
project  development  than  ever  before.  As  a  result,  the  use  of 
new technology is accelerating innovation across our asset base, 
improving productivity and optimizing program economics. Our well 
performance, on an absolute and lateral-adjusted basis, increased 
21% year-over-year to an average 30-day peak rate of more than 
1,400 Boepd.

Pairing our top-tier asset quality with strong execution, Concho  
is focused on driving operational excellence to create shareholder 
value  while  maintaining  our  commitment  to  operating  safely  
and responsibly. 

Better Begins with
Financial Strength

Better shareholder returns are built on a foundation of 
operational excellence and prudent capital allocation. 
We are focused on what we are doing today to drive 
operational  efficiency,  while  planning  for  tomorrow 
by  building  our  competencies  and  managing  risk. 
During  the  year,  our  commitment  to  maintaining  a 
strong balance sheet was evident. We completed debt 
management  transactions  that  reduced  our  annual 
interest expense by more than $15 million (pro forma 
for RSP Permian) and ended the year with investment-
grade credit ratings from Fitch, Moody’s and S&P. Free 
cash flow drives our financial strength, and we again 
executed a capital program aligned with cash flow.1

Growing  and  generating  free  cash  flow  is  a  central  objective  of 
our capital allocation approach and, ultimately, our broader value 
creation strategy. Concho has a strong track record of demonstrating 
our  ability  to  execute  a  disciplined  capital  program  within  cash 
flow. During the year we invested $2.5 billion for exploration and 
development  and  generated  approximately  $2.6  billion  of  cash 
flow from operating activities, marking the third consecutive year 
that operating cash exceeded cash used in investing activities for 
exploration and development. Our strong and consistent cash flow 
gives  us  the  flexibility  to  invest  in  our  high-return  projects  and 
capitalize  on  opportunities  when  they  arise — setting  the  stage 
for enhanced future returns. 

Our new capital allocation framework is built on this track record 
of  strong  production  growth  and  free  cash  flow  generation.  In 
December 2018, we announced plans to initiate a regular quarterly 
dividend which began in the first quarter of 2019, demonstrating 
our  confidence  in  the  strength  of  our  portfolio.  By  delivering 
substantial  free  cash  flow,  we  expect  to  create  meaningful  and 
sustainable value for all Concho shareholders. 

1 Free cash flow is a non-GAAP term that means cash flow provided by  
  operating activities in excess of cash flow used in investing activities for  
  additions to oil and gas properties.

declines in, the sustained depression of, or increased volatility in the prices we receive for our oil and natural gas, or 
increases in the differential between index oil or natural gas prices and prices received; 

drilling, completion and operating risks, including our ability to efficiently execute large-scale project development as we 
could experience delays, curtailments and other adverse impacts associated with a high concentration of activity; 

the  effects  of  government  regulation,  permitting  and  other  legal  requirements,  including  new  legislation  or  regulation 
related to hydraulic fracturing, climate change or derivatives reform;

other processing and transportation considerations; 

risks related to ongoing expansion of our business, including the recruitment and retention of qualified personnel in the 
Permian Basin; 

competition in the oil and natural gas industry; 

risks related to the concentration of our operations in the Permian Basin of Southeast New Mexico and West Texas; 

the  costs  and  availability  of  equipment,  resources,  services  and  qualified  personnel  required  to  perform  our  drilling, 
completion and operating activities; 

environmental hazards, such as uncontrollable flows of oil, natural gas, saltwater, well fluids, toxic gas or other pollution 
into the environment, including groundwater contamination; 

uncertainties about the estimated quantities of oil and natural gas reserves; 

risks  associated  with  acquisitions  such  as  increased  expenses  and  integration  efforts,  failure  to  realize  the  expected 
benefits of the transaction and liabilities associated with acquired properties or businesses;

potential financial losses or earnings reductions from our commodity price risk-management program; 

difficult and adverse conditions in the domestic and global capital and credit markets; 

the adequacy of our capital resources and liquidity including, but not limited to, access to additional borrowing capacity 
under our Credit Facility, as defined herein; 

the impact of potential changes in our credit ratings; 

uncertainties about our ability to successfully execute our business and financial plans and strategies; 

uncertainties about our ability to replace reserves and economically develop our current reserves; 

general economic and business conditions, either internationally or domestically; and 

uncertainty concerning our assumed or possible future results of operations. 

Reserve engineering is a process of estimating underground accumulations of oil and natural gas that cannot be measured in an 
exact way. The accuracy of any reserve estimate depends on the quality of available data, the interpretation of such data and the price 
and cost assumptions made by our reserve engineers. In addition, the results of drilling, testing and production activities may justify 
revisions of estimates that were made previously. If significant, such revisions would change the schedule of any further production and 
development drilling. Accordingly, reserve estimates may differ from the quantities of oil and natural gas that are ultimately recovered.

Item 1. Business 

General 

PART I 

Concho Resources Inc., a Delaware corporation (“Concho,” the “Company,” “we,” “us” and “our”) formed in February 2006, 
is an independent oil and natural gas company engaged in the acquisition, development, exploration and production of oil and 
natural gas properties. Our operations are primarily focused in the Permian Basin of Southeast New Mexico and West Texas. 
The Permian Basin is one of the most prolific oil and natural gas producing regions in the United States and is characterized by 
an extensive production history, long reserve life, multiple producing horizons and recovery potential. Concho’s legacy in the 
Permian  Basin  provides  us  a  deep  understanding  of  operating  and  geological  trends,  and  we  are  actively  developing  our 
resource  base  utilizing  large-scale  development  projects,  which  include  long-lateral  wells  and  multi-well  pad  locations, 
throughout our operating areas. Our strategy remains focused on development and exploration activities on our multi-year project 
inventory, and pursuing acquisitions that meet our strategic and financial objectives. 

Business and Properties 

Our  operations  are  focused  in  the  Permian  Basin,  which  underlies  an  area  of  Southeast  New  Mexico  and West  Texas 
approximately 250 miles wide and 300 miles long. Commercial accumulations of hydrocarbons occur in multiple stratigraphic 
horizons,  at  depths  ranging  from  less  than  1,000 feet  to  over  25,000 feet.  At  December 31,  2018,  our  1,187  MMBoe  total 
estimated proved reserves consisted of approximately 63 percent oil and 37 percent natural gas. We have assembled a multi-
year inventory of horizontal development and exploration projects across our operating areas.  

We  have  one  operating  segment  and  one  reporting  unit,  which  is  oil  and  natural  gas  development,  exploration  and 

production. All of our operations are conducted in one geographic area of the United States. 

On July 19, 2018, we completed the acquisition of RSP Permian, Inc. (“RSP”) through an all-stock transaction (the “RSP 
Acquisition”). RSP was an independent oil and natural gas company engaged in the acquisition, exploration, development and 
production  of  oil  and  natural gas  reserves in  the  Permian Basin.  The  vast  majority  of  RSP’s  acreage  was  located  on  large, 
contiguous  acreage  blocks  in  the  core  of  the  Midland  Basin  and  the  Delaware  Basin.  The  acquisition  added  approximately 
92,000 net acres to our asset portfolio.  

Following the RSP Acquisition, we simplified our asset structure, changing from four operating areas to two – comprising 
the Midland Basin and the Delaware Basin, which includes our assets in the Northern Delaware Basin, Southern Delaware Basin 
and New Mexico Shelf. 

The following table summarizes our drilling activity during the periods indicated:

Our operations are focused in the Delaware Basin and the Midland Basin, within the greater Permian Basin. In both areas, 
we  are  transitioning  our  development  to  large-scale  manufacturing  mode,  which  includes  leveraging  our  experience  and 
expertise to maximize resource recovery and program economics while optimizing well spacing, landing intervals, lateral length 
and completion techniques. 

Delaware Basin. At December 31, 2018, we had estimated proved reserves in this area of 674 MMBoe, representing 57 
percent of our total proved reserves. During the year ended December 31, 2018, we commenced drilling or participated in the 
drilling of 281 (171 net) wells in this area, and we completed 239 (136 net) wells that are producing. 

The  Delaware  Basin  is  characterized  by  a  thick,  resource-rich  hydrocarbon  column  that  lends  itself  to  multi-zone 
development.  We  leverage  leading-edge  horizontal  drilling  and  completion  technologies,  utilizing  multi-well  pad  sites  and 
extended lateral lengths to develop multiple producing formations. Our current activity is focused primarily on the Avalon, Bone 
Spring and Wolfcamp formations, which generally range from 6,500 feet to 13,500 feet.  

Midland Basin. At December 31, 2018, we had estimated proved reserves in this area of 513 MMBoe, representing 43 
percent of our total proved reserves. During the year ended December 31, 2018, we commenced drilling or participated in the 
drilling of 147 (95 net) wells in this area, and we completed 111 (68 net) wells that are producing. 

Our primary objectives in the Midland Basin area are the Spraberry and Wolfcamp formations, which generally range from 
7,500 feet to 11,500 feet. We are developing these formations with horizontal drilling, utilizing multi-well pad sites and extended 
lateral development.

Marketing Arrangements 

General. We market our oil and natural gas in accordance with standard energy industry practices. The marketing effort 
endeavors to obtain the combined highest netback and most secure market available at that time. In addition, marketing supports 
our operations group as it relates to the planning and preparation of future development activity so that available markets can 
be assessed and secured. This planning also involves the coordination of access to the physical facilities necessary to connect 
forthcoming wells as timely and efficiently as possible. 

Oil. We generally sell production at the lease to third-party purchasers. We generally do not transport, refine or process the 
oil we produce. Most of our Delaware Basin production in New Mexico is connected to the Alpha Crude Connector, LLC (“ACC”) 
pipeline system. This production is then primarily purchased by five different purchasers.  

Most  of  our  Delaware  Basin  production  in  Texas  is  connected  to  one  of  five  different  gathering  systems.  One  of  these 
systems is a crude oil gathering and transportation system operated by a subsidiary of Oryx Southern Delaware Holdings, LLC 
(“Oryx”), an entity in which we own a 23.75 percent membership interest. A significant portion of our Midland Basin production 
is on one of seven different gathering systems. The remaining portion of our production is sold via truck transport. We sell our 
produced oil under contracts using market-based pricing, which is adjusted for differentials based upon delivery location and oil 
quality. 

Natural Gas. We consider all natural gas gathering, treating and processing service providers in the areas of our production 
and evaluate market options to obtain the best price reasonably available given the necessary operating conditions. We sell the 
majority of our natural gas under individually negotiated natural gas purchase contracts using market-based pricing. The majority 
of our natural gas is subject to long-term agreements that generally extend five to ten years from the effective date of the subject 
contract. 

The majority of our natural gas is casinghead gas, which is sold at the lease location under (i) percentage of proceeds 
processing contracts, (ii) fee-based contracts or (iii) a hybrid of percentage of proceeds and fee-based contracts. The purchaser

gathers our casinghead natural gas in the field where it is produced and transports it via pipeline to natural gas processing plants 
where natural gas liquid products are extracted and sold by the processors. The portion of natural gas remaining after liquid 
extraction is residue gas, which is placed on residue pipeline systems downstream of the processing plant. Under our percentage 
of proceeds and hybrid percentage of proceeds and fee-based contracts, we receive a percentage of the value for the extracted 
liquids and the residue gas. Under our fee-based contracts, we receive natural gas liquids and residue gas value, less the fee 
component thereof, or are invoiced the fee component of the purchaser’s service. 

Our Principal Customers 

We  sell  our  oil  and  natural  gas  production  principally  to  marketers  and  other  purchasers  that  have  access  to  pipeline 
facilities.  In  areas  where  there  is  no  practical  access  to  pipelines,  oil  is  transported  to  storage  facilities  by  trucks  owned  or 
otherwise arranged by the marketers or purchasers. Our marketing of oil and natural gas can be affected by factors beyond our 
control, the effects of which cannot be accurately predicted.  

For 2018, revenues from oil and natural gas sales to Plains Marketing and Transportation, Inc. accounted for approximately 
18 percent of our total operating revenues. While the loss of this purchaser may result in a temporary interruption in sales of, or 
a lower price for, our production, we believe that the loss of this purchaser would not have a material adverse effect on our 
operations, as there are alternative purchasers in our producing regions. See Note 13 of the Notes to Consolidated Financial 
Statements included in “Item 8. Financial Statements and Supplementary Data.” 

Competition 

The oil and natural gas industry in the areas in which we operate is highly competitive. We encounter strong competition 
from  numerous  parties,  ranging  generally  from  small  independent  producers  to  major  integrated  companies.  We  primarily 
encounter significant competition in acquiring properties. At higher commodity prices, we also face competition in contracting for 
drilling, pressure pumping and workover equipment and securing trained personnel. Many of these competitors have financial, 
technical  and  personnel  resources  substantially  larger  than  ours.  As  a  result,  our  competitors  may  be  able  to  pay  more  for 
desirable  properties,  or  to  evaluate,  bid  for  and  purchase  a  greater  number  of  properties  or  prospects  than  our  financial  or 
personnel resources will permit. 

In addition to competition for drilling, pressure pumping and workover equipment, we are also affected by the availability of 
related equipment and materials. The oil and natural gas industry periodically experiences shortages of drilling and workover 
rigs, equipment, pipe, materials and personnel, which can delay drilling, workover and exploration activities and cause significant 
price increases. We are unable to predict the timing or duration of any such shortages.

Working Capital 

Based  on  current  market  conditions,  we  have  maintained  a  stable  liquidity  position.  Our  principal  source  of  liquidity  is 
available borrowing capacity under our credit facility, as amended and restated (the “Credit Facility”). At December 31, 2018, we 
had $242 million of debt outstanding and $1,756 million of unused commitments under our Credit Facility, net of letters of credit. 
Our primary needs for cash are development, exploration and acquisitions of oil and natural gas assets, payment of contractual 
obligations and working capital obligations. However, additional borrowings under our Credit Facility or the issuance of additional 
debt securities will require a greater portion of our cash flow from operations to be used for the payment of interest and principal 
on our debt, thereby reducing our ability to use cash flow to fund working capital, capital expenditures and acquisitions. 

Applicable Laws and Regulations 

Regulation of Production 

The production of oil and natural gas is subject to regulation under a wide range of local, state and federal statutes, rules, 
orders and regulations. Federal, state and local statutes and regulations require permits for drilling operations, drilling bonds 
and  reports  concerning  operations.  All  of  the  states  in  which  we  own  and  operate  properties  have  regulations  governing 
conservation matters, including provisions for the unitization or pooling of oil and natural gas properties, the establishment of 
maximum  allowable  rates of production  from  oil  and natural  gas  wells,  the  regulation  of  well  spacing, and  the  plugging  and 
abandonment of wells. The effect of these regulations is to limit the amount of oil and natural gas that we can produce from our 
wells  and  to  limit  the  number  of  wells  or  the  locations  at  which  we  can  drill,  although  we  can  apply  for  exceptions  to  such 
regulations or to have reductions in well spacing. Moreover, each state generally imposes a production or severance tax with 
respect to the production and sale of oil, natural gas and natural gas liquids within its jurisdiction. The failure to comply with 
these rules and regulations can result in substantial penalties. Our competitors in the oil and natural gas industry are subject to 
the same regulatory requirements and restrictions that affect our operations. 

Environmental, Health and Safety Matters 

General. Our  operations  are  subject  to  stringent  and  complex  federal,  state  and  local  laws  and  regulations  governing 
environmental protection as well as the discharge of materials into the environment. These laws, rules and regulations may, 
among other things: 

• 

• 

• 

• 

• 

• 

require the acquisition of various permits before drilling commences; 

require notice to stakeholders of proposed and ongoing operations; 

require the installation of expensive pollution control equipment; 

restrict the types, quantities and concentration of various substances that can be released into the environment 
in connection with oil and natural gas drilling and production and saltwater disposal activities; 

limit or prohibit drilling activities on certain lands lying within wilderness, wetlands and other protected areas, 
or otherwise restrict or prohibit activities that could impact the environment, including water resources; and 

require remedial measures to mitigate pollution from former and ongoing operations, such as requirements to 
close pits and plug abandoned wells. 

These laws, rules and regulations may also restrict the production rate of oil and natural gas below the rate that would 
otherwise be possible. The regulatory burden on the oil and natural gas industry increases the cost of doing business in the 
industry and consequently affects profitability. Violations and liabilities with respect to these laws and regulations could result in 
significant  administrative,  civil  or  criminal  penalties,  remedial  clean-ups,  natural  resource  damages,  permit  modifications  or 
revocations,  operational  interruptions  or  shutdowns  and  other  liabilities.  The  costs  of  remedying  such  conditions  may  be 
significant,  and  remediation  obligations  could  adversely  affect  our  financial  condition,  results  of  operations  and  leasehold 
acreage.  Additionally,  environmental  laws  and  regulations  are  revised  frequently,  and  any  changes,  including  changes  in 
implementation or interpretation, that result in more stringent and costly waste handling, disposal and cleanup requirements for 
the oil and natural gas industry could have a significant impact on our operating costs. 

The following is a summary of some of the existing laws, rules and regulations to which our business is subject. 

Waste  handling. The  Resource  Conservation  and  Recovery  Act  (“RCRA”)  and  comparable  state  statutes  regulate  the 
generation,  transportation,  treatment,  storage,  disposal  and  cleanup  of  hazardous  and  non-hazardous  wastes.  Pursuant  to 
regulatory guidance issued by the federal Environmental Protection Agency (the “EPA”), the individual states administer some 
or all of the provisions of RCRA, sometimes in conjunction with their own, more stringent requirements. Drilling fluids, produced 
waters, and most of the other wastes associated with the exploration, development, and production of oil or natural gas are 
currently  regulated  under  RCRA’s  non-hazardous  waste  provisions.  However,  it  is  possible  that  certain  oil  and  natural  gas 

8 

 
 
 
  
  
  
 
 
 
 
 
 
 
 
 
 
exploration and production wastes now classified as non-hazardous could be classified as hazardous wastes in the future. For 
example, in December 2016, the EPA and certain environmental organizations entered into a consent decree to address EPA’s 
alleged failure to timely assess its RCRA Subtitle D criteria regulations exempting certain exploration and production related oil 
and natural gas wastes from regulation as hazardous wastes under RCRA. The consent decree requires EPA to propose a 
rulemaking no later than March 15, 2019 for revision of certain Subtitle D criteria regulations pertaining to oil and natural gas 
wastes or to sign a determination that revision of the regulations is not necessary. Any such change could result in an increase 
in our costs to manage and dispose of wastes, which could have a material adverse effect on our results of operations and 
financial position. Also, in the course of our operations, we generate some amounts of ordinary industrial wastes, such as paint 
wastes,  waste  solvents  and  waste  oils  that  may  be  regulated  as  hazardous  wastes  if  such  wastes  have  hazardous 
characteristics. 

Comprehensive  Environmental  Response,  Compensation  and  Liability  Act. The  Comprehensive  Environmental 
Response Compensation and Liability Act (“CERCLA”), also known as the Superfund law, imposes joint and several liability, 
without regard to fault or legality of conduct, on classes of persons who are considered to be responsible for the release of a 
hazardous substance into the environment. These persons include the current or former owner or operator of the site where the 
release occurred, and anyone who disposed or arranged for the disposal of a hazardous substance released at the site. Under 
CERCLA, such persons may be subject to strict, joint and several liability for the costs of cleaning up the hazardous substances 
that have been released into the environment, for damages to natural resources and for the costs of certain health studies. In 
addition, it is not uncommon for neighboring landowners and other third parties to file claims for personal injury and property 
damage allegedly caused by the hazardous substances released into the environment. Each state, including Texas, also has 
environmental cleanup laws analogous to CERCLA. 

We  currently  own,  lease,  or  operate  numerous  properties  that  have  been  used  for  oil  and  natural  gas  exploration  and 
production for many years. Although we believe that we have utilized operating and waste disposal practices that were standard 
in the industry at the time, hazardous substances, wastes or hydrocarbons may have been released on or under the properties 
owned or leased by us, or on or under other locations, including off-site locations, where such substances have been taken for 
disposal. In addition, some of our properties have been operated by third parties or by previous owners or operators whose 
storage, treatment and disposal of hazardous substances, wastes or hydrocarbons were not under our control. These properties 
and the substances disposed or released on them may be subject to CERCLA, RCRA and analogous state laws. Under such 
laws, we could be required to remove previously disposed substances and wastes, remediate contaminated property, or perform 
remedial operations to prevent future contamination. 

Water  discharges. The  federal  Water  Pollution  Control  Act  (the  “Clean  Water  Act”)  and  analogous  state  laws,  impose 
restrictions and strict controls with respect to the discharge of pollutants, including spills and leaks of oil and other substances, 
into waters of the United States. The discharge of pollutants into regulated waters, including dredge and fill activities in regulated 
wetlands, is prohibited, except in accordance with the terms of a permit issued by the EPA, or, in some circumstances, the U.S. 
Army Corps of Engineers (the “Corps”), or an analogous state agency. In addition, spill prevention, control and countermeasure 
requirements under federal law require appropriate containment berms and similar structures to help prevent the contamination 
of  navigable  waters  in  the  event  of  a  petroleum  hydrocarbon  tank  spill,  rupture  or  leak.  Further,  the  Clean  Water  Act  and 
analogous state laws require individual permits or coverage under general permits for discharges of storm water runoff from 
certain types of facilities. Federal and state regulatory agencies can impose administrative, civil and criminal penalties for non-
compliance with discharge permits or other requirements of the Clean Water Act and analogous state laws and regulations. 

In September 2015, new EPA and Corps rules to revise the definition of “waters of the United States” (“WOTUS”) for all 
Clean Water Act programs, thereby defining the scope of the EPA’s and the Corps’ jurisdiction, became effective. To the extent 
the rule expands the scope of jurisdiction of the Clean Water Act, we could face increased costs and delays with respect to 
obtaining permits for dredge and fill activities in wetland areas. The rule has been challenged in court on the grounds that it 
unlawfully expands the reach of Clean Water Act programs, and implementation of the rule has been stayed pending resolution 
of  the  court  challenge.  In  response  to  this  decision,  the  EPA  and  the  Corps  resumed  nationwide  use  of  the  agencies’  prior 
regulations defining the term “waters of the United States.” Those regulations will be implemented as they were prior to the 
effective  date  of  the  new  WOTUS  rule.  In  January  2017,  the  U.S.  Supreme  Court  accepted  review  of  the  WOTUS  rule  to 
determine whether jurisdiction to hear challenges to the rule rests with the federal district or appellate courts. In June 2017, the 
EPA and the Corps proposed a rule that would initiate the first step in a two-step process intended to review and revise the 
definition of “waters of the United States.” Under the proposal, the first step would be to rescind the May 2015 final rule and put 
back into effect the narrower language defining “waters of the United States” under the Clean Water Act that existed prior to the 
rule. The second step would be a notice-and-comment rule-making in which the agencies will conduct a substantive reevaluation 
of the definition of “waters of the United States.” In January 2018, the Supreme Court ruled that the WOTUS rule must first be 
reviewed in federal district courts, remanding the case at issue to the district level and putting the status of the Sixth Circuit’s 
stay of the new rule into question. Citing uncertainty caused by litigation, the EPA subsequently announced a two year stay of 
the application of the rule as it undertakes its own review of the rule. Federal district court decisions have preserved the stay of 
the  2015  Clean  Water  Rule  in  Texas  and  New  Mexico,  which  remain  subject  to  pre-2015  WOTUS  regulations.  Litigation 
surrounding this rule is ongoing. More recently, on December 11, 2018, the EPA and the Corps released a proposal to revise 
the 2015 Clean Water Rule so as to narrow the regulatory definition of waters of the U.S., with a 60-day comment period to 
follow. The scope of the jurisdictional reach of the Clean Water Act will likely remain uncertain for several years.

Safe Drinking Water Act. Our oil and natural gas exploration and production operations generate produced water, drilling 
muds, and other waste streams, some of which may be disposed via injection in underground wells situated in non-producing 
subsurface formations. The drilling and operation of these injection wells are regulated by the federal Safe Drinking Water Act 
(the  “SDWA”).  The  Underground  Injection Well  Program  under  the  SDWA  requires  that  we  obtain  permits  from  the  EPA  or 
delegated state agencies for our disposal wells, establishes minimum standards for injection well operations, restricts the types 
and quantities of fluids that may be injected and prohibits the migration of fluid containing any contaminants into underground 
sources of drinking water. Any leakage from the subsurface portions of the injection wells may cause degradation of freshwater, 
potentially  resulting  in  cancellation  of  operations  of  a  well,  imposition  of  fines  and  penalties  from  governmental  agencies, 
incurrence  of  expenditures  for  remediation  of  affected  resources,  and  imposition  of  liability  by  landowners  or  other  parties 
claiming damages for alternative water supplies, property damages, and personal injuries. Any changes in the laws or regulations 
or the inability to obtain permits for new injection wells in the future may affect our ability to dispose of produced waters and 
would  ultimately  increase  the  cost  of  our  operations,  which  costs  could  be  significant.  For  example,  in  2014  the  Railroad 
Commission of Texas (the “RRC”) adopted additional permit rules for injection wells to address seismic activity concerns within 
the state. Among other things, the rules require companies seeking permits for disposal wells to provide seismic activity data in 
permit applications, provide for more frequent monitoring and reporting for certain wells, and allow the RRC to modify, suspend, 
or terminate permits on grounds that a disposal well is likely to be, or determined to be, causing seismic activity. Furthermore, 
in  response  to  recent  seismic  events  near  underground  injection  wells  used  for  the  disposal  of  oil  and  natural  gas-related 
wastewaters, federal and some state agencies have begun investigating whether such wells have caused increased seismic 
activity, and some states have shut down or imposed moratoria on the use of such injection wells. For example, in 2016, the 
Oklahoma Corporation Commission issued various orders and regulations applicable to disposal operations in specific counties 
in  Oklahoma.  These  rules  require  that  disposal  well  operators,  among  other  things,  conduct  additional  mechanical  integrity 
testing,  make  sure  that  their  wells  are  not  injecting  wastes  into  targeted  formations,  and/or  reduce  the  volumes  of  wastes 
disposed in such wells. If new regulatory initiatives are implemented that restrict or prohibit the use of underground injection 
wells in areas where we rely upon the use of such wells in our operations, our costs to operate may significantly increase, and 
our  ability  to  continue  production  may  be  delayed  or  limited,  which  could  have  a  material  adverse  effect  on  our  results  of 
operations and financial position. 

Air  emissions. The  federal  Clean  Air  Act  (the  “CAA”),  and  comparable  state  laws  regulate  emissions  of  various  air 
pollutants through air emissions permitting programs and the imposition of other requirements. New facilities may be required 
to obtain permits before work can begin, and existing facilities may be required to obtain additional permits and incur capital 
costs in order to remain in compliance. These and other laws and regulations may increase the costs of compliance for some 
facilities  where  we  operate.  Obtaining  or  renewing  permits  also  has  the  potential  to  delay  the  development  of  our  projects. 
Federal and state regulatory agencies can impose administrative, civil and criminal penalties for non-compliance with air permits 
or other requirements of the CAA and associated state laws and regulations. In addition, the EPA has developed, and continues 
to develop, stringent regulations governing emissions of toxic air pollutants at specified sources. 

For example, in October 2015, the EPA lowered the National Ambient Air Quality Standard (“NAAQS”) for ozone from 75 
to 70 parts per billion. By July 2018, the EPA finished issuing area designations with respect to ground-level ozone for U.S. 
counties as either "attainment/unclassifiable" or "unclassifiable." Reclassification of areas of state implementation of the revised 
NAAQS could result in stricter permitting requirements, delay or prohibit our ability to obtain such permits, and result in increased 
expenditures for pollution control equipment, the costs of which could be significant. In addition, in June 2016, the EPA finalized 
rules  under  the  CAA  regarding  criteria  for  aggregating  multiple  sites  into  a  single  source  for  air-quality  permitting  purposes 
applicable to the oil and gas industry. This rule could cause small facilities (such as tank batteries), on an aggregate basis, to 
be deemed a major source, thereby triggering more stringent air permitting requirements, which in turn could result in operational 
delays or require us to install costly pollution control equipment. In a separate rulemaking in June 2016, the EPA finalized new 
air emission control requirements for emissions of methane from certain equipment and processes in the oil and natural gas 
source category, including production, processing, transmission and storage activities. The final rule package includes first-time 
standards to address emissions of methane from equipment and processes across the source category, including hydraulically 
fractured oil and natural gas well completions, and also imposes leak detection and repair requirements on operators. In addition, 
the rule package extends existing volatile organic compound (“VOC”) standards under the EPA’s Subpart OOOO of the New 
Source  Performance  Standards  to include  previously  unregulated  equipment  within  the  oil  and natural gas source  category. 
However, in June 2017, the EPA proposed a two year stay of the fugitive emissions monitoring requirements, pneumatic pump 
standards, and closed vent system certification requirements in the 2016 New Source Performance Standards rule for the oil 
and  gas  industry  while  it  reconsiders  these  aspects  of  the  rule.  On  September  11,  2018,  the  EPA  proposed  targeted 
improvements  to  the  rule,  including  amendments  to  the  rule’s  fugitive  emissions  monitoring  requirements,  and  expects  to 
“significantly reduce” the regulatory burden of the rule in doing so. The U.S. Bureau of Land Management (the “BLM”) finalized 
similar rules in November 2016 that limit methane emissions from new and existing oil and natural gas operations on federal 
lands through limitations on the venting and flaring of gas, as well as enhanced leak detection and repair requirements. The 
BLM adopted final rules in January 2017. Operators generally had one year from the January 2017 effective date to come into 
compliance with the rule’s requirements. However, in December 2017, the BLM temporarily suspended or delayed certain of 
these requirements set forth in its Venting and Flaring Rule until January 2019, and in September 2018 the BLM proposed a 
revised rule which scaled back the waste-prevention requirements of the 2016 rule. Environmental groups sued in federal district 
court a day later to challenge the legality of aspects of the revised rule, and the outcome of this litigation is currently uncertain. 
These air emission rules have the potential to increase our compliance costs. 

10 

 
 
 
 
Climate change. In response to findings that emissions of carbon dioxide, methane and other “greenhouse gases” (“GHGs”) 
present an endangerment to public health and the environment, the EPA has issued regulations to restrict emissions of GHGs 
under  existing  provisions  of  the  CAA.  These  regulations  include  limits  on  tailpipe  emissions  from  motor  vehicles  and 
preconstruction and operating permit requirements for certain large stationary sources. The EPA has also adopted rules requiring 
the reporting of GHG emissions from specified large GHG emission sources in the United States, as well as certain onshore oil 
and natural gas production facilities, on an annual basis, including GHG emissions resulting from the completion and workover 
operations of hydraulically fractured oil wells. Recent federal regulatory action with respect to climate change has focused on 
methane  emissions.  As  noted  above,  both  the  EPA  and  the  BLM  finalized  rules  in  2016  that  limit  methane  emissions  from 
upstream oil and natural gas exploration and production operations. Increased regulation of methane and other GHGs have the 
potential to result in increased compliance costs and, consequently, adversely affect our operations. 

On August 3, 2015, the EPA also issued new regulations limiting carbon dioxide emissions from existing power generation 
facilities. Under these regulations, nationwide carbon dioxide emissions would be reduced by approximately 30 percent from 
2005 levels by 2030 with a flexible interim goal. Several industry groups and states challenged the rule. On February 9, 2016, 
the U.S. Supreme Court stayed the implementation of this rule pending judicial review. On March 28, 2017, President Trump 
signed an Executive Order directing the EPA to review the regulations, and on April 4, 2017, the EPA announced that it was 
reviewing the 2015 carbon dioxide regulations. On April 28, 2017, the U.S. Court of Appeals for the District of Columbia stayed 
the litigation pending the current administration’s review. That stay was extended for another 60 days on August 8, 2017. On 
October 10, 2017, the EPA initiated the formal rulemaking process to repeal the regulations. In August 2018, the EPA proposed 
the Affordable Clean Energy rule as a replacement to the 2015 regulations. The EPA’s proposals are subject to public comment 
and likely legal challenge, and as such, we cannot predict at this time what impact the rulemaking will have on the demand for 
oil and natural gas production and our operations. 

While Congress has from time to time considered legislation to reduce emissions of GHGs, there has not been significant 
activity in the form of adopted legislation to reduce emissions of GHGs in recent years. In the absence of Congressional action, 
many states have established rules aimed at reducing GHG emissions, including GHG cap and trade programs. Most of these 
cap and trade programs work by requiring major sources of emissions, such as electric power plants, or major producers of 
fuels,  such  as  refineries  and  natural  gas  processing  plants,  to  acquire  and  surrender  emission  allowances.  The  number  of 
allowances available  for purchase  is  reduced each  year in  an effort  to  achieve the  overall  GHG  emission  reduction  goal. In 
addition, in 2015, the United States participated in the United Nations Conference on Climate Change, which led to the creation 
of  the  Paris  Agreement.  The  Paris  Agreement  requires  countries  to  review  and  “represent  a  progression”  in  their  intended 
nationally determined contributions, which set GHG emission reduction goals, every five years beginning in 2020. However, in 
June  2017,  President  Trump  announced  that  the  United  States  plans  to  withdraw  from  the  Paris  Agreement  and  seek 
negotiations  either  to  reenter  the  Paris  Agreement  on  different  terms  or  establish  a  new  framework  agreement.  The  Paris 
Agreement provides for a four-year exit process beginning in November 2016, which would result in an effective exit date of 
November 2020. The United States’ adherence to the exit process or the terms on which the United States may reenter the 
Paris Agreement or a separately negotiated agreement are unclear at this time. 

The  adoption  of  legislation  or  regulatory  programs  to  reduce  emissions  of  GHGs  could  require  us  to  incur  increased 
operating  costs,  such  as  costs  to  purchase  and  operate  emissions  control  systems,  to  acquire  emissions  allowances,  or  to 
comply with new regulatory or reporting requirements. Any such legislation or regulatory programs could also increase the cost 
of consuming, and thereby reduce demand for, the oil and natural gas we produce. Reduced demand for the oil and natural gas 
that  we  produce  could  also  have  the  effect  of  lowering  the  value  of  our  reserves.  Consequently,  legislation  and  regulatory 
programs  to  reduce  emissions  of  GHGs  could  have  an  adverse  effect  on  our  business,  financial  condition  and  results  of 
operations. It should also be noted that some scientists have concluded that increasing concentrations of GHGs in the earth’s 
atmosphere may produce climate changes that have significant physical effects, such as increased frequency and severity of 
storms, droughts, and floods and other climatic events. If any such effects were to occur, they could have an adverse effect on 
our financial condition and results of operations. Finally, increasing attention to the risks of climate change has resulted in an 
increased possibility of lawsuits brought by public and private entities against oil and gas companies in connection with their 
GHG emissions. Should we be targeted by any such litigation, we may incur liability, which, to the extent that societal pressures 
or political or other factors are involved, could be imposed without regard to our causation of or contribution to the asserted 
damage, or to other mitigating factors. 

Hydraulic fracturing. Hydraulic fracturing is an important and common practice that is used to stimulate production of oil 
and/or natural gas from dense subsurface rock formations. The hydraulic fracturing process involves the injection of water, sand, 
and chemicals under pressure into the formation to fracture the surrounding rock and stimulate production. We routinely use 
hydraulic fracturing as part of our operations. The process is typically regulated by state oil and natural gas commissions, but 
the EPA has asserted federal regulatory authority pursuant to the SDWA over certain hydraulic fracturing activities involving the 
use of diesel and issued guidance in February 2014 governing such activities. The EPA has also issued final regulations under 
the  CAA  establishing  performance  standards,  including  standards  for  the  capture  of  VOCs  and  methane  released  during 
hydraulic fracturing (although the EPA has temporarily suspended or delayed compliance with certain of these standards as 
they undergo an administrative review); an advanced notice of proposed rulemaking under the Toxic Substances Control Act to 
require companies to disclose information regarding the chemicals used in hydraulic fracturing; and final rules in June 2016 that 
prohibit  the  discharge  of  wastewater  from  hydraulic  fracturing  operations  to  publicly  owned  wastewater  treatment  plants. 
Moreover, in March 2015, the BLM issued a final rule that imposes requirements on hydraulic fracturing activities on federal and 
Indian  lands,  including  new  requirements  relating  to  public  disclosure,  wellbore  integrity  and  handling  of  flowback  water. 

11 

 
 
 
 
 
However, the BLM lacked authority to promulgate the rule. While that decision was on appeal, the BLM rescinded this rule in 
December 2017. In January 2018, the state of California and a coalition of environmental groups filed a lawsuits in the Northern 
District of California to challenge the BLM’s rescission of the 2015 rule. This litigation is ongoing and future implementation of 
the rule is uncertain at this time. 

At  the  state  level,  several  states  have  adopted  or  are  considering  legal  requirements  that  could  impose  more  stringent 
permitting, disclosure, and well construction requirements on hydraulic fracturing activities. For example, New Mexico and Texas 
have adopted hydraulic fracturing fluid disclosure requirements, and the RRC has also adopted rules governing well casing, 
cementing and other standards for ensuring that hydraulic fracturing operations do not contaminate nearby water resources. In 
addition, local governments have also taken steps to regulate hydraulic fracturing, including imposing restrictions or moratoria 
on oil and natural gas activities occurring within their boundaries. If new or more stringent federal, state, or local legal restrictions 
relating to the hydraulic fracturing process are adopted in areas where we operate, we could incur potentially significant added 
costs  to  comply  with  such  requirements,  experience  delays  or  curtailment  in  the  pursuit  of  exploration,  development,  or 
production activities, and perhaps even be precluded from drilling wells. 

In addition, certain governmental reviews are either underway or being proposed that focus on environmental aspects of 
hydraulic  fracturing  practices. For  example,  in  December 2016,  the  EPA  released its  final  report  on  the  potential  impacts  of 
hydraulic fracturing on drinking water resources. The final report concluded that “water cycle” activities associated with hydraulic 
fracturing may impact drinking water resources under some circumstances, noting that the following hydraulic fracturing water 
cycle activities and local- or regional-scale factors are more likely than others to result in more frequent or more severe impacts: 
water withdrawals for fracturing in times or areas of low water availability; surface spills during the management of fracturing 
fluids,  chemicals  or  produced  water;  injection  of  fracturing  fluids  into  wells  with  inadequate  mechanical  integrity;  injection  of 
fracturing fluids directly into groundwater resources; discharge of inadequately treated fracturing wastewater to surface waters; 
and disposal or storage of fracturing wastewater in unlined pits. Since the report did not find a direct link between hydraulic 
fracturing itself and contamination of groundwater resources, this years-long study report does not appear to provide any basis 
for further regulation of hydraulic fracturing at the federal level. 

We do not have  insurance  policies in effect  that  are  intended  to provide  coverage  for  losses  solely  related  to  hydraulic 
fracturing operations; however, we believe our well control, general liability and excess liability insurance policies may cover 
third-party claims related to hydraulic fracturing operations and associated legal expenses in accordance with, and subject to, 
the terms of such policies. If new laws or regulations significantly restrict hydraulic fracturing activities or impose burdens on 
new permitting or operating requirements, our ability to utilize hydraulic fracturing may be curtailed, and this may in turn reduce 
the amount of oil and natural gas that we are ultimately able to produce from our reserves. 

Operations on Federal Lands. We currently operate on federal lands under the jurisdiction of the BLM. Permitting for oil 
and natural gas activities on federal lands can take significantly longer than the state permitting process. Delays in obtaining 
permits necessary can disrupt our operations and have an adverse effect on our business. As noted above, in November 2016, 
the BLM finalized rules that restrict methane emissions from oil and natural gas activities on federal lands by limiting venting and 
flaring of natural gas from wells and other equipment. The final rule also requires operators to pay royalties to the BLM on flared 
gas  from  wells  already  connected  to  gas capture  infrastructure, and  allows  the  agency  to  set  royalty  rates  at  or above 12.5 
percent of the value of production. These rules could result in increased compliance costs for our operations, which in turn could 
have an adverse effect on our business and results of operations. 

Endangered species. The federal Endangered Species Act (the “ESA”) and analogous state laws regulate activities that 
could have an adverse effect on threatened or endangered species. Some of our drilling operations are conducted in areas 
where  protected species are known  to  exist.  In  these areas,  we  may  be  obligated  to  develop and  implement plans  to  avoid 
potential adverse impacts to protected species, and we may be prohibited from conducting drilling operations in certain locations 
or during certain seasons, such as breeding and nesting seasons, when our operations could have an adverse effect on the 
species. It is also possible that a federal or state agency could order a complete halt to drilling activities in certain locations if it 
is determined that such activities may have a serious adverse effect on a protected species. The presence of a protected species 
in areas where we perform drilling activities could impair our ability to timely complete drilling and developmental operations and 
could adversely affect our future production from those areas. The designation of previously unprotected species as threatened 
or endangered in areas where we or our oil and natural gas exploration and production customers operate could cause us or 
our customers to incur increased costs arising from species protection measures and could result in delays or limitations in our 
customers’ performance of operations, which could reduce demand for our midstream services. 

National Environmental Policy Act. Oil and natural gas exploration and production activities on federal lands are subject 
to the National Environmental Policy Act (“NEPA”). NEPA requires federal agencies, including the Department of Interior, to 
evaluate major agency actions having the potential to significantly impact the environment. In the course of such evaluations, 
an agency will prepare an environmental assessment that assesses the potential direct, indirect and cumulative impacts of a 
proposed project and, if necessary, will prepare a more detailed environmental impact statement that may be made available 
for  public  review  and comment.  All  of  our  current  exploration  and production activities, as  well  as proposed  exploration  and 
development plans, on federal lands require governmental permits that are subject to the requirements of NEPA. This process 
has the potential to delay or even halt development of some of our oil and natural gas projects. 

12 

 
 
 
 
 
 
 
  
OSHA and other laws and regulations. We are subject to the requirements of the federal Occupational Safety and Health 
Act (“OSHA”) and comparable state statutes. The OSHA hazard communication standard, the EPA community right-to-know 
regulations  under  Title III  of  CERCLA  and  similar  state  statutes  require  that  we  organize  and/or  disclose  information  about 
hazardous  materials  used  or  produced  in  our  operations.  Also,  pursuant  to  OSHA,  the  Occupational  Safety  and  Health 
Administration has established a variety of standards relating to workplace exposure to hazardous substances and employee 
health and safety. 

We are not aware of any existing environmental issues, claims or regulations that will require us to incur material capital 
expenditures  during  2019,  and  we  did  not  incur  material  capital  expenditures  relating  to  environmental  issues,  claims  or 
regulations during 2018. However, we cannot assure that the passage or application of more stringent laws or regulations or the 
application of existing laws in the future will not require us to incur material capital expenditures or have a material adverse effect 
on our financial position or results of operations. 

Our Employees 

Our corporate headquarters are located at One Concho Center, 600 West Illinois Avenue, Midland, Texas 79701. We also 
maintain various field offices in Texas and New Mexico. At December 31, 2018, we had 1,503 employees, 569 of whom were 
employed  in  field  operations.  Our  future  success  will  depend  partially  on  our  ability  to  attract,  retain  and  motivate  qualified 
personnel. We are not a party to any collective bargaining agreements and have not experienced any strikes or work stoppages. 
We consider our relations with our employees to be good.

Non-GAAP Financial Measures and Reconciliations 

Reconciliation of Standardized Measure to PV-10 

PV-10 is derived from the standardized measure of discounted future net cash flows, which is the most directly comparable 
GAAP financial measure. PV-10 is a computation of the standardized measure of discounted future net cash flows on a pre-tax 
basis. PV-10 is equal to the standardized measure of discounted future net cash flows at the applicable date, before deducting 
future income taxes, discounted at 10 percent. We believe that the presentation of PV-10 is relevant and useful to investors 
because it presents the discounted future net cash flows attributable to our estimated proved reserves prior to taking into account 
future corporate income taxes, and it is a useful measure for evaluating the relative monetary significance of our oil and natural 
gas assets. Further, investors may utilize the measure as a basis for comparison of the relative size and value of our reserves 
to other companies. We use this measure when assessing the potential return on investment related to our oil and natural gas 
assets. PV-10, however, is not a substitute for the standardized measure of discounted future net cash flows. Our PV-10 measure 
and the standardized measure of discounted future net cash flows do not purport to present the fair value of our oil and natural 
gas reserves. 

The following table provides a reconciliation of the GAAP standardized measure of discounted future net cash flows to PV-

Reconciliation of Net Income (Loss) to Adjusted EBITDAX 

Adjusted EBITDAX (as defined below) is presented herein and reconciled from the GAAP measure of net income (loss) 

because of its wide acceptance by the investment community as a financial indicator. 

We define Adjusted EBITDAX as net income (loss), plus (1) exploration and abandonments, (2) depreciation, depletion and 
amortization, (3) accretion of discount on asset retirement obligations, (4) impairments of long-lived assets, (5) non-cash stock-
based  compensation,  (6)  (gain)  loss  on derivatives,  (7)  net  cash  receipts  from  (payments  on)  derivatives,  (8)  (gain)  loss  on 
disposition  of  assets,  net,  (9) interest  expense,  (10)  loss  on  extinguishment  of  debt,  (11)  gain  on  equity  method  investment 
distribution, (12) RSP transaction costs and (13) federal and state income tax expense (benefit). Adjusted EBITDAX is not a 
measure of net income (loss) or cash flows as determined by GAAP. 

Our Adjusted EBITDAX measure provides additional information that may be used to better understand our operations. 
Adjusted  EBITDAX  is  one of several  metrics  that  we  use as  a  supplemental  financial  measurement  in  the  evaluation  of  our 
business  and  should  not  be  considered  as  an  alternative  to,  or  more  meaningful  than,  net  income  (loss)  as  an  indicator  of 
operating  performance.  Certain  items  excluded  from  Adjusted  EBITDAX  are  significant  components  in  understanding  and 
assessing a company’s financial performance, such as a company’s cost of capital and tax structure, as well as the historic cost 
of depreciable and depletable assets. Adjusted EBITDAX, as used by us, may not be comparable to similarly titled measures 
reported by other companies. We believe that Adjusted EBITDAX is a widely followed measure of operating performance and is 
one of many metrics used by our management team and by other users of our consolidated financial statements. For example, 
Adjusted EBITDAX can be used to assess our operating performance and return on capital in comparison to other independent 
exploration and production companies without regard to financial or capital structure and to assess the financial performance of 
our assets and our Company without regard to capital structure or historical cost basis.

Item 1A.  Risk Factors 

You should consider carefully the following risk factors together with all of the other information included in this report and 
other reports filed with the SEC before investing in our securities. If any of the following risks were actually to occur, our business, 
financial condition or results of operations could be materially adversely affected. In that case, the trading price of our securities 
could decline and you could lose all or part of your investment. 

Risks Related to Our Business 

Oil and natural gas are volatile. A decline in oil and natural gas prices could adversely affect our financial position, financial 
results, cash flow, access to capital and ability to grow. 

Our future financial condition, revenues, results of operations, rate of growth and the carrying value of our oil and natural 
gas properties depend primarily upon the prices we receive for our oil and natural gas production and the prices prevailing from 
time to time for oil and natural gas. Oil and natural gas prices historically have been volatile and are likely to continue to be 
volatile in the future, especially given current geopolitical conditions. This price volatility also affects the amount of cash flow we 
have  available  for  capital  expenditures  and  our  ability  to  borrow  money  or  raise  additional  capital.  The  prices  and  levels  of 
production for oil and natural gas are subject to a variety of factors beyond our control, including: 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

the overall global demand for oil and natural gas; 

the overall global supply of oil and natural gas; 

the overall North American oil and natural gas supply and demand fundamentals, including: 

• 

the U.S. economy, 

•  weather conditions, and 

• 

liquefied natural gas (“LNG”) deliveries to and exports from the United States; 

economic conditions worldwide; 

the level of global crude oil, crude oil products and LNG inventories; 

volatility and trading patterns in the commodity-futures markets; 

political and economic developments in oil and natural gas producing regions, including Africa, South America 
and the Middle East; 

the extent to which members of the Organization of Petroleum Exporting Countries and other oil exporting 
nations are able to influence global oil supply levels; 

technological advances affecting energy consumption and energy supply; 

the  proximity,  capacity,  cost  and  availability  of  pipelines  and  other  transportation  facilities,  as  well  as  the 
availability of commodity processing and gathering and refining capacity; 

the effect of energy conservation efforts; 

additional restrictions on the exploration, development and production of oil, natural gas and natural gas liquids 
so as to materially reduce emissions of carbon dioxide and methane GHGs; 

political and economic events that directly or indirectly impact the relative strength or weakness of the U.S. 
dollar, on which oil prices are benchmarked globally, against foreign currencies;  

domestic and foreign governmental regulations, including limits on the United States’ ability to export crude 
oil, and taxation; 

the cost and availability of products and personnel needed for us to produce oil and natural gas, including rigs, 
crews, sand, water and water disposal; 

risks related to the concentration of our operations in the Permian Basin of Southeast New Mexico and West 
Texas and the level of commodity inventory in the Permian Basin; 

16 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
• 

• 

the quality of the oil we produce; and 

the price, availability and acceptance of alternative fuels. 

Furthermore, oil and natural gas prices continued to be volatile in 2018. For example, NYMEX oil prices in 2018 ranged 
from a high of $76.41 to a low of $42.53 per Bbl and the NYMEX natural gas prices in 2018 ranged from a high of $4.84 to a low 
of $2.55 per MMBtu. Further, the NYMEX oil prices and NYMEX natural gas prices reached highs of $55.59 per Bbl and $3.59 
per MMBtu, respectively, during the period from January 1, 2019 to February 15, 2019. 

Declines in oil and natural gas prices would not only reduce our revenue, but could also reduce the amount of oil and natural 
gas that we can produce economically. This in turn would lower the amount of oil and natural gas reserves we could recognize 
and, as a result, could have a material adverse effect on our financial condition and results of operations. If the oil and natural 
gas industry experiences significant price declines for a sustained period, we may, among other things, be unable to maintain 
or increase our borrowing capacity, repay current or future indebtedness or obtain additional capital on attractive terms, all of 
which can adversely affect the value of our securities.  

Approximately  31  percent  of  our  total  estimated  proved  reserves  at  December  31,  2018  were  undeveloped,  and  those 
reserves may not ultimately be developed. 

At December 31, 2018, approximately 31 percent of our total estimated proved reserves were undeveloped. Recovery of 
undeveloped reserves requires significant capital expenditures and successful drilling. Our reserves data assumes that we can 
and  will  make  these  expenditures  and  conduct  these  operations  successfully.  These  assumptions,  however,  may  not  prove 
correct. Our reserve report at December 31, 2018 includes estimates of total future development costs over the next five years 
associated with our proved undeveloped reserves of approximately $3.3 billion. If we choose not to spend the capital to develop 
these reserves, or if we are not otherwise able to successfully develop these reserves, we will be required to write-off these 
reserves. In addition, under the SEC’s reserve rules, because proved undeveloped reserves may be recognized only if they 
relate to wells planned to be drilled within five years of the date of their initial recognition, we may be required to write-off any 
proved undeveloped reserves that are not developed within this five-year timeframe. For example, as of December 31, 2018, 
we wrote-off approximately 77 MMBoe of proved undeveloped reserves primarily because we no longer expect to develop these 
reserves within five years of the date of their initial recognition. 

Drilling for and producing oil and natural gas are high-risk activities with many uncertainties that could cause our costs to 
increase or production volumes to decrease, which would reduce our cash flows. 

Our future financial condition and results of operations depend on the success of our exploration and production activities. 
Our oil and natural gas exploration and production activities are subject to numerous risks beyond our control, including the risk 
that drilling will not result in commercially viable oil and natural gas production. Our decisions to purchase, explore, develop or 
otherwise  exploit  prospects  or  properties  will  depend  in  part  on  the  evaluation  of  data  obtained  through  geophysical  and 
geological analyses, production data and engineering studies, the results of which are often inconclusive or subject to varying 
interpretations.  Our  cost  of  drilling,  completing,  equipping  and  operating  wells  is  often  uncertain  before  drilling  commences. 
Overruns in budgeted expenditures are common risks that can make a particular project uneconomical or less economical than 
forecasted. Further, many factors may curtail, delay or cancel drilling, including the following: 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

shortages  of  or  delays  in  obtaining  equipment  and  qualified  personnel  or  in  obtaining  sand  or  water  for 
hydraulic fracturing activities; 

delays imposed by or resulting from compliance with regulatory and contractual requirements; 

reductions in oil and natural gas prices; 

delays and costs of drilling wells on lands subject to complex development terms and circumstances; 

oil or natural gas gathering, transportation and processing availability restrictions or limitations; 

pressure or irregularities in geological formations; 

equipment failures or accidents; 

adverse weather conditions and natural disasters; 

political events, public protests, civil disturbances, terrorist acts or cyber attacks; 

environmental hazards, such as natural gas leaks, oil and produced water spills, pipeline and tank ruptures, 
encountering naturally occurring radioactive materials, and unauthorized discharges of brine, well stimulation 
and completion fluids, toxic gases or other pollutants into the surface and subsurface environment;

• 

• 

• 

• 

• 

• 

surface access restrictions; 

failure to obtain regulatory and third-party approvals; 

actions by third-party operators of our properties; 

loss of title or other title related issues; 

limitations in the market for oil and natural gas; and 

limited availability of financing at acceptable terms. 

The occurrence of one or more of these factors could result in a partial or total loss of our investment in a particular property, 
as  well  as  significant  liabilities.  Moreover,  certain  of  these events  could  result  in environmental  pollution  and  impact  to  third 
parties,  including  persons  living  in  proximity  to  our  operations,  our  employees  and  employees  of  our  contractors,  leading  to 
possible injuries, death or significant damage to property and natural resources. 

In addition, the results of our exploratory drilling in new or emerging plays are more uncertain than drilling results in areas 
that  are  developed  and  have  established  production.  Since  new  or  emerging  plays  and  new  formations  have  limited  or  no 
production history, we are unable to use past drilling results in those areas to help predict our future drilling results. As a result, 
our cost of drilling, completing and operating wells in these areas may be higher than initially expected, and the value of our 
undeveloped acreage will decline if drilling results are unsuccessful. 

Multi-well pad drilling and project development may result in volatility in our operating results. 

We utilize multi-well pad drilling and project development where practical. Project development may involve more than one 
multi-well pad being drilled and completed at one time in a relatively confined area. Wells drilled on a pad or in a project may 
not be brought into production until all wells on the pad or project are drilled and completed. Problems affecting one pad or a 
single well could adversely affect production from all of the wells on the pad or in the entire project. As a result, multi-well pad 
drilling and project development can cause delays in the scheduled commencement of production, or interruptions in ongoing 
production. These delays or interruptions may cause declines or volatility in our operating results due to timing as well as declines 
in oil and natural gas prices. Further, any delay, reduction or curtailment of our development and producing operations, due to 
operational delays caused by multi-well pad drilling or project development, or otherwise, could result in the loss of acreage 
through lease expirations. 

Additionally, infrastructure expansion, including more complex facilities and takeaway capacity, could become challenging 
in  project  development  areas.  Managing capital  expenditures  for  infrastructure  expansion  could  cause  economic constraints 
when considering design capacity. 

Prolonged decreases in our drilling program may require us to pay certain non-use fees or impact our ability to comply 
with certain contractual requirements.  

Oil prices declined substantially during the second half of 2014 and continued to decline through 2016, but began to recover 
in 2017 and through most of 2018, although pricing remains volatile. In the event that oil prices decline for a sustained period, 
we may experience significant decreases in drilling activity. Due to the nature of our drilling programs and the oil and natural gas 
industry in general, we are a party to certain agreements that require us to meet various contractual obligations or require us to 
utilize a certain amount of goods or services, including, but not limited to, water commitments, throughput volume commitments, 
power commitments and drilling commitments. In the event that oil and natural gas prices decrease, and as a result continue to 
reduce the demand for drilling and production, this could lead to a decrease in our drilling activity and production levels, which 
could,  in  turn,  require  us  to  pay  for  unutilized  goods  or  services  or  impact  our  ability  to  meet  these  contractual  obligations, 
including drilling commitments that may result in lease expirations if unmet. 

We may incur losses as a result of title defects in our oil and natural gas properties. 

It is our practice to initially conduct only a cursory title review of the oil and natural gas properties on which we do not have 
proved  reserves.  To  the  extent  title  opinions  or other  investigations  prior  to  our commencement of  drilling operations  reflect 
defects  affecting  such  properties,  we  are  typically  responsible  for  curing  any  such  defects  at  our  expense. Additionally,  the 
discovery of any such defects could delay or prohibit the commencement of drilling operations on the affected properties. These 
impacts and other potential losses resulting from title defects in our oil and natural gas properties could have a material adverse 
effect on our business, financial condition and results of operations. 

Our operations are substantially dependent on the availability of water and our ability to dispose of produced water 
gathered  from  drilling  and  production  activities. Restrictions  on  our  ability  to  obtain  water  or  dispose  of  produced 
water may have an adverse effect on our financial condition, results of operations and cash flows.

Water is an essential component of both the drilling and hydraulic fracturing processes. Historically, we have been able to 
purchase water from local land owners and other sources for use in our operations. Over the past few years, extreme drought 
conditions persisted in Southeast New Mexico and West Texas. Although conditions have improved, we cannot guarantee what 
conditions may occur in the future. Severe drought conditions can result in local water districts taking steps to restrict the use of 
water subject to their jurisdiction for drilling and hydraulic fracturing in order to protect the local water supply. If we are unable to 
obtain water to use in our operations from local sources, we may be unable to economically produce oil and natural gas, which 
could have an adverse effect on our financial condition, results of operations and cash flows. 

In addition, we must dispose of the fluids produced from oil and natural gas production operations, including produced water, 
which we do directly or through the use of third party vendors. The legal requirements related to the disposal of produced water 
into a non-producing geologic formation by means of underground injection wells are subject to change based on concerns of 
the public or governmental authorities regarding such disposal activities. One such concern arises from recent seismic events 
near underground disposal wells that are used for the disposal by injection of produced water resulting from oil and natural gas 
activities. In March 2016, the United States Geological Survey identified Texas and Colorado as being among the states with 
areas  of  increased  rates  of  induced  seismicity  that  could  be  attributed  to  fluid  injection  or  oil  and  natural  gas  extraction.  In 
response  to  concerns  regarding  induced  seismicity,  regulators  in  some  states  have  imposed,  or  are  considering  imposing, 
additional requirements in the permitting of produced water disposal wells to assess any relationship between seismicity and 
the use of such wells. For example, in Texas, the RRC adopted new rules governing the permitting or re-permitting of wells used 
to  dispose  of produced  water and  other  fluids  resulting  from  the production of oil  and  natural gas  in  order  to  address  these 
seismic activity concerns within the state. Among other things, these rules require companies seeking permits for disposal wells 
to provide seismic activity data in permit applications, provide for more frequent monitoring and reporting for certain wells and 
allow  the  state  to  modify, suspend  or terminate permits  on grounds that  a  disposal  well is  likely  to  be,  or  determined  to  be, 
causing seismic activity. States may issue orders to temporarily shut down or to curtail the injection depth of existing wells in the 
vicinity of seismic events.  

Another consequence of seismic events may be lawsuits alleging that disposal well operations have caused damage to 
neighboring properties or otherwise violated state and federal rules regulating waste disposal. These developments could result 
in additional regulation and restrictions on the use of injection wells by us or by commercial disposal well vendors whom we may 
use from time to time to dispose of produced water. Increased regulation and attention given to induced seismicity could also 
lead to greater opposition, including litigation to limit or prohibit oil and natural gas activities utilizing injection wells for produced 
water disposal.  

Any one or more of these developments may result in us or our vendors having to limit disposal well volumes, disposal rates 
and pressures or locations, or require us or our vendors to shut down or curtail the injection into disposal wells, which events 
could have a material adverse effect on our business, financial condition and results of operations. 

Federal, state and local legislation and regulatory initiatives relating to hydraulic fracturing, as well as governmental 
reviews of such activities, could result in increased costs and additional operating restrictions or delays and adversely 
affect our production. 

Hydraulic fracturing is an important and common practice that is used to stimulate production of hydrocarbons from tight 
formations. We routinely utilize hydraulic fracturing techniques in many of our drilling and completion programs. The process 
involves  the  injection  of  water,  sand  and  chemicals  under  pressure  into  the  formation  to  fracture  the  surrounding  rock  and 
stimulate production. The process is typically regulated by state oil and natural gas commissions. However, the EPA recently 
asserted federal regulatory authority over hydraulic fracturing involving diesel additives under the SDWA’s Underground Injection 
Control Program and issued guidance in February 2014, governing such activities. The EPA has also issued: final regulations 
under the CAA establishing performance standards, including standards for the capture of VOCs and methane released during 
hydraulic fracturing (although the EPA has temporarily suspended or delayed compliance with certain of these standards as 
they undergo an administrative review); an advanced notice of proposed rulemaking under the Toxic Substances Control Act to 
require companies to disclose information regarding the chemicals used in hydraulic fracturing; and final rules in June 2016 to 
prohibit  the  discharge  of  wastewater  from  hydraulic  fracturing  operations  to  publicly  owned  wastewater  treatment  plants. 
Moreover, in March 2015, the BLM issued a final rule that imposes requirements on hydraulic fracturing activities on federal and 
Indian  lands,  including  new  requirements  relating  to  public  disclosure,  wellbore  integrity  and  handling  of  flowback  water. 
However, the BLM lacked authority to promulgate the rule. While that decision was on appeal, the BLM rescinded this rule in 
December 2017. In January 2018, the state of California and a coalition of environmental groups filed a lawsuit in the Northern 
District of California to challenge the BLM’s rescission of the 2015 rule. This litigation is ongoing and future implementation of 
the rule is uncertain at this time. 

At  the  state  level,  several  states  have  adopted  or  are  considering  legal  requirements  that  could  impose  more  stringent 
permitting, disclosure, and well construction requirements on hydraulic fracturing activities. For example, New Mexico and Texas 
have adopted hydraulic fracturing fluid disclosure requirements, and the RRC has also adopted rules governing well casing, 
cementing and other standards for ensuring that hydraulic fracturing operations do not contaminate nearby water resources. In 
addition, local governments have also taken steps to regulate hydraulic fracturing, including imposing restrictions or moratoria 
on oil and natural gas activities occurring within their boundaries. If new or more stringent federal, state, or local legal restrictions 
relating to the hydraulic fracturing process are adopted in areas where we operate, we could incur potentially significant added 

19 

 
 
 
 
 
 
 
 
costs  to  comply  with  such  requirements,  experience  delays  or  curtailment  in  the  pursuit  of  exploration,  development,  or 
production activities, and perhaps even be precluded from drilling wells.  

In addition, certain governmental reviews are either underway or being proposed that focus on environmental aspects of 
hydraulic  fracturing  practices. For  example,  in  December 2016,  the  EPA  released its  final  report  on  the  potential  impacts  of 
hydraulic fracturing on drinking water resources. The final report concluded that “water cycle” activities associated with hydraulic 
fracturing may impact drinking water resources under some circumstances, noting that the following hydraulic fracturing water 
cycle activities and local- or regional-scale factors are more likely than others to result in more frequent or more severe impacts: 
water withdrawals for fracturing in times or areas of low water availability; surface spills during the management of fracturing 
fluids,  chemicals  or  produced  water;  injection  of  fracturing  fluids  into  wells  with  inadequate  mechanical  integrity;  injection  of 
fracturing fluids directly into groundwater resources; discharge of inadequately treated fracturing wastewater to surface waters; 
and disposal or storage of fracturing wastewater in unlined pits. Since the report did not find a direct link between hydraulic 
fracturing itself and contamination of groundwater resources, this years-long study report does not appear to provide any basis 
for further regulation of hydraulic fracturing at the federal level. 

If new laws or regulations that significantly restrict hydraulic fracturing are adopted, such laws could make it more difficult 
or costly for us to perform fracturing to stimulate production from tight formations. In addition, if hydraulic fracturing becomes 
regulated at the federal level as a result of federal legislation or regulatory initiatives by the EPA, our fracturing activities could 
become subject to additional permitting requirements and could also result in permitting delays and potential cost increases. 
Restrictions on hydraulic fracturing could also reduce the amount of oil and natural gas that we are ultimately able to produce 
from our reserves. 

Climate change legislation, regulations restricting emissions of “greenhouse gases” or legal or other action taken by public 
or private entities related to climate change could result in increased operating costs and reduced demand for the oil and 
natural gas that we produce. 

In response to findings that emissions of carbon dioxide, methane and other greenhouse gases present an endangerment 
to public health and the environment, the EPA has issued regulations to restrict emissions of GHGs under existing provisions of 
the CAA. These regulations include limits on tailpipe emissions from motor vehicles and preconstruction and operating permit 
requirements for certain large stationary sources. The EPA has also adopted rules requiring the reporting of GHG emissions 
from  specified  large  GHG  emission  sources  in  the  United  States,  as  well  as  certain  onshore  oil  and  natural  gas  production 
facilities, on an annual basis, including GHG emissions resulting from the completion and workover operations of hydraulically 
fractured  oil  wells.  Recent  federal  regulatory  action  with  respect to climate  change  has  focused  on  methane  emissions.  For 
example,  in  June  2016,  the  EPA  finalized  new  air  emission  controls  for  emissions  of  methane  from  certain  equipment  and 
processes in the oil and natural gas source category, including production, processing, transmission and storage activities. The 
final rule package includes first-time standards to address emissions of methane from equipment and processes across the 
source category, including hydraulically fractured oil and natural gas well completions, and also imposes leak detection and 
repair requirements on operators. However, in June 2017, the EPA proposed a two year stay of fugitive emissions monitoring 
requirements, pneumatic pump standards, and closed vent system certification requirements in the 2016 rule while it reconsiders 
these aspects of the rule. Additionally, on September 11, 2018, the EPA proposed targeted improvements to the 2016 rule, 
including  amendments  to  the  rule’s  fugitive  emissions  monitoring  requirements,  and  expects  to  “significantly  reduce”  the 
regulatory burden of the rule in doing so. The BLM finalized similar rules in November 2016 that limit methane emissions from 
new and existing oil and natural gas operations on federal lands through limitations on the venting and flaring of gas, as well as 
enhanced leak detection and repair requirements but then finalized a revised rule in 2018 which scaled back the waste prevention 
requirements of the 2016 rule. Environmental groups have sued in federal district court to challenge the legality of aspects of 
the revised rule, and the outcome of this litigation is currently uncertain. These methane emission rules have the potential to 
increase our compliance costs. 

While Congress has from time to time considered legislation to reduce emissions of GHGs, there has not been significant 
activity in the form of adopted legislation to reduce emissions of GHGs in recent years. In the absence of Congressional action, 
many states have established rules aimed at reducing GHG emissions, including GHG cap and trade programs. Most of these 
cap and trade programs work by requiring major sources of emissions, such as electric power plants, or major producers of 
fuels,  such  as  refineries  and  natural  gas  processing  plants,  to  acquire  and  surrender  emission  allowances.  The  number  of 
allowances available for purchase is reduced each year in an effort to achieve the overall GHG emission reduction goal. In the 
future, the United States may also choose to adhere to international agreements targeting GHG reductions. 

The  adoption  of  legislation  or  regulatory  programs  to  reduce  emissions  of  GHGs  could  require  us  to  incur  increased 
operating costs, such as costs to purchase and operate emissions control systems, to acquire emissions allowances or to comply 
with  new  regulatory  or  reporting  requirements.  Any  such  legislation  or  regulatory  programs  could  also  increase  the  cost  of 
consuming,  and  thereby  reduce  demand  for,  the  oil  and  natural  gas  we  produce.  Consequently,  legislation  and  regulatory 
programs  to  reduce  emissions  of  GHGs  could  have  an  adverse  effect  on  our  business,  financial  condition  and  results  of 
operations. Reduced demand for the oil and natural gas that we produce could also have the effect of lowering the value of our 
reserves. It should also be noted that some scientists have concluded that increasing concentrations of GHGs in the earth’s 
atmosphere may produce climate changes that have significant physical effects, such as increased frequency and severity of 
storms, droughts, and floods and other climatic events. If any such effects were to occur, they could have an adverse effect on 
our  financial  condition  and  results  of  operations.  In  addition,  there  have  also  been  efforts  in  recent  years  to  influence  the 

20 

 
 
 
 
 
 
 
investment community, including investment advisors and certain sovereign wealth, pension and endowment funds promoting 
divestment of fossil fuel equities and pressuring lenders to limit funding to companies engaged in the extraction of fossil fuel 
reserves. Such environmental activism and initiatives aimed at limiting climate change and reducing air pollution could interfere 
with our business activities, operations and ability to access capital. Finally, increasing attention to the risks of climate change 
has resulted in an increased possibility of lawsuits or investigations brought by public and private entities against oil and natural 
gas companies in connection with their GHG emissions. Should we be targeted by any such litigation or investigations, we may 
incur liability, which, to the extent that societal pressures or political or other factors are involved, could be imposed without 
regard to the causation of or contribution to the asserted damage, or to other mitigating factors. The ultimate impact of GHG 
emissions-related agreements, legislation and measures on our company’s financial performance is highly uncertain because 
the Company is unable to predict with certainty, for a multitude of individual jurisdictions, the outcome of political decision-making 
processes and the variables and tradeoffs that inevitably occur in connection with such processes. 

Estimates of proved reserves and future net cash flows are not precise. The actual quantities of our proved reserves and our 
future net cash flows may prove to be lower than estimated. 

Numerous uncertainties exist in estimating quantities of proved reserves and future net cash flows therefrom. Our estimates 
of  proved  reserves  and  related  future  net  cash  flows  are  based  on  various  assumptions,  which  may  ultimately  prove  to  be 
inaccurate. 

Petroleum engineering is a subjective process of estimating accumulations of oil and natural gas that cannot be measured 
in an exact manner. Estimates of economically recoverable oil and natural gas reserves and of future net cash flows depend 
upon a number of variable factors and assumptions, including the following: 

• 

• 

• 

• 

• 

historical production from the area compared with production from other producing areas; 

the assumed effects of regulations by governmental agencies; 

the quality, quantity and interpretation of available relevant data; 

assumptions concerning future commodity prices; and 

assumptions  concerning  future  operating  costs,  severance  and  ad  valorem  taxes,  development  costs  and 
workover and remedial costs. 

Because  all  reserve  estimates  are  to  some  degree subjective,  each  of  the  following  items,  or  other  items  not  identified 

below, may differ materially from those assumed in estimating reserves: 

• 

• 

• 

• 

the quantities of oil and natural gas that are ultimately recovered; 

the production and operating costs incurred; 

the amount and timing of future development expenditures; and 

future commodity prices. 

Furthermore, different reserve engineers may make different estimates of reserves and cash flows based on the same data. 
Our  actual  production,  revenues  and  expenditures  with  respect  to  reserves  will  likely  be  different  from  estimates  and  the 
differences may be material. 

As required by the SEC, the estimated discounted future net cash flows from proved reserves are based on the average 
previous twelve months first-of-month prices preceding the date of the estimate and costs as of the date of the estimate, while 
actual future prices and costs may be materially higher or lower. Actual future net cash flows also will be affected by factors such 
as: 

• 

• 

• 

• 

the amount and timing of actual production;  

levels of future capital spending; 

increases or decreases in the supply of or demand for oil and natural gas; and 

changes in governmental regulations or taxation. 

Accordingly, estimates included herein of future net cash flows may be materially different from the future net cash flows 
that are ultimately received. Therefore, the estimates of discounted future net cash flows in this report should not be construed 
as accurate estimates of the current market value of our proved reserves.

Our  business  requires  substantial  capital  expenditures.  We  may  be  unable  to  obtain  needed  capital  or  financing  on 
satisfactory terms or at all, which could lead to a decline in our oil and natural gas reserves. 

The  oil  and  natural  gas  industry  is  capital  intensive.  We  make  and  expect  to  continue  to  make  substantial  capital 
expenditures for the acquisition, exploration and development of oil and natural gas reserves. At December 31, 2018, we had 
approximately $242 million of debt outstanding under our Credit Facility (and total debt at December 31, 2018 of $4.2 billion), 
and we had approximately $1.8 billion of unused commitments under our Credit Facility. Expenditures for acquisition, exploration 
and  development  of  oil  and  natural  gas  properties  are  the primary  use  of  our  capital  resources. We  incurred  approximately 
$10.4 billion  in  acquisition,  exploration  and  development  costs  during  the  year  ended  December 31,  2018,  of  which 
approximately $7.6 billion related to the RSP Acquisition. In October 2018, our board of directors approved our 2019 capital 
budget, excluding acquisitions, of up to approximately $3.8 billion. With current commodity prices, we expect to spend between 
$2.8 billion and $3.0 billion on drilling and completion activity. We plan to spend approximately $3.3 billion over the next five 
years on future development costs associated with proved undeveloped reserves. 

We intend to finance our future capital expenditures, other than significant acquisitions, through cash flow from operations 
and, if necessary, through borrowings under our Credit Facility. However, our cash flow from operations and access to capital 
are subject to a number of variables, including: 

• 

• 

• 

• 

• 

• 

• 

• 

• 

the volume of oil and natural gas we are able to produce from existing wells; 

our ability to transport our oil and natural gas to market; 

the prices at which our commodities are sold;  

the costs of producing oil and natural gas; 

global credit and securities markets;  

the ability and willingness of lenders and investors to provide capital and the cost of the capital; 

our ability to acquire, locate and produce new reserves; 

the impact of potential changes in our credit ratings; and 

our proved reserves. 

We  may  not  generate  expected  cash  flows  and  may  have  limited  ability  to  obtain  the  capital  necessary  to  sustain  our 
operations at current or anticipated levels. A decline in cash flow from operations or our financing needs may require us to revise 
our capital program or alter or increase our capitalization substantially through the issuance of debt or equity securities. The 
issuance of additional equity securities could have a dilutive effect on the value of our common stock. Additional borrowings 
under our Credit Facility or the issuance of additional debt securities will require that a greater portion of our cash flow from 
operations be used for the payment of interest and principal on our debt, thereby reducing our ability to use cash flow to fund 
working capital, capital expenditures and acquisitions. In addition, our Credit Facility imposes certain limitations on our ability to 
incur additional indebtedness other than indebtedness under our Credit Facility. If we desire to issue additional debt securities 
other than as expressly permitted under our Credit Facility, we will be required to seek the consent of the lenders in accordance 
with the requirements of our Credit Facility, which consent may be withheld by the lenders at their discretion. Additional financing 
also may not be available on acceptable terms or at all. In the event additional capital resources are unavailable, we may curtail 
drilling, development and other activities or be forced to sell some of our assets on an untimely or unfavorable basis. 

The failure to obtain additional financing could result in a curtailment of our operations relating to the development of our 
undeveloped acreage or the curtailment of acquisitions that may be favorable to us, which in turn could lead to a decline in our 
oil and natural gas reserves, and could adversely affect our production, revenues and results of operations. 

A decline in general economic, business or industry conditions could have a material adverse effect on our results of 
operations. 

A global economic downturn, particularly with respect to the U.S. economy or the oil and natural gas industry, and global 
financial and credit market disruptions reduce the availability of liquidity and credit to fund the continuation and expansion of 
industrial business operations worldwide, which can result in a slowdown in economic activity. Reduced worldwide demand for 
energy often results in lower commodity prices, which will reduce our cash flows and may affect our borrowing ability. If the 
economic  climate  in  the  United  States  or  abroad  deteriorates,  we  may  be  unable  to  obtain  needed  capital  or  financing  on 
satisfactory terms, which could lead to a decline in our reserves as existing reserves are depleted. Lower commodity prices may 
also reduce the amount of oil and natural gas that we can produce economically, which could ultimately decrease our net revenue 
and profitability. In addition, reduced worldwide demand for securities issued by oil and natural gas companies or depressed 

22 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
trading prices of the debt and equity securities of oil and natural gas companies generally may depress the market value of our 
securities or make it more difficult for us to raise capital. 

Recently  enacted  legislation  will  affect  our  tax  position;  however,  certain  federal  income  tax  deductions  currently 
available with respect to oil and natural gas exploration and development may be eliminated. Additional state taxes on 
oil and natural gas extraction may be imposed, as a result of future legislation. 

In December 2017, Congress enacted the budget reconciliation act commonly referred to as the Tax Cuts and Jobs Act 
(“TCJA”). The law made significant changes to U.S. federal income tax laws, including reducing the corporate income tax rate 
from  35  percent  to  21 percent,  repealing  the  corporate alternative minimum  tax  (“AMT”),  partially  limiting  the  deductibility  of 
interest expense and net operating losses (“NOLs”), eliminating the deduction for certain U.S. production activities and allowing 
the immediate deduction of certain new investments in lieu of depreciation expense over time. Although we have evaluated the 
TCJA and recorded adjustments as required in our financial statements, many aspects of the TCJA are unclear and may not be 
clarified for some time. We will continue to monitor any new administrative guidance or tax law interpretation.  

In recent years, U.S. lawmakers have proposed certain significant changes to U.S. tax laws applicable to oil and natural 
gas companies. These changes include, but are not limited to: (i) the elimination of current deductions for intangible drilling and 
development costs; (ii) the repeal of the percentage depletion allowance for oil and natural gas properties; and (iii) an extension 
of the amortization period for certain geological and geophysical expenditures. Although these changes were not included in the 
TCJA, it is unclear whether any such changes will be enacted or if enacted, when such changes could be effective. If such 
proposed changes were to be enacted, as well as any similar changes in state law, it could eliminate or postpone certain tax 
deductions  that are  currently available  to  us  with  respect  to  oil  and  natural  gas  exploration  and development,  and  any such 
change could negatively affect our financial condition and results of operations. 

Additionally, future legislation could be enacted that increases the taxes or fees imposed on oil and natural gas extraction. 
Any such legislation could result in increased operating costs and/or reduced consumer demand for petroleum products, which 
in turn could affect the prices we receive for our oil and natural gas. 

Our ability to use our existing net operating loss carryforwards or other tax attributes could be limited. 

At December 31, 2018, we had approximately $2.2 billion of federal NOL carryforwards available to offset against future 
taxable  income.  Of  these  NOL  carryforwards,  $1.5  billion  were  generated  prior  to  the  effective  date  of  new  limitations  on 
utilization of NOLs imposed by the TCJA and are allowable as a deduction against 100 percent of taxable income in future years 
but will begin to expire in the tax year 2034. The estimated current year NOL of approximately $675 million is subject to an 80 
percent limitation but has an indefinite carryforward life. Included in our $2.2 billion of federal NOL carryforwards is approximately 
$516 million net NOLs that we acquired as part of the RSP Acquisition. These acquired tax attributes are subject to an annual 
limitation under Section 382 of the Internal Revenue Code of 1986, as amended (“Section 382”). However, based on the annual 
limitation amount, the NOLs and credits are expected to be fully utilizable by the tax year 2022. 

Utilization of any NOL depends on many factors, including our ability to generate future taxable income, which cannot be 
assured. In addition, Section 382 generally imposes an annual limitation on the amount of NOLs that may be used to offset 
taxable income when a corporation has undergone an “ownership change” (as determined under Section 382). An ownership 
change generally occurs if one or more stockholders (or groups of stockholders) who are each deemed to own at least five 
percent of our stock change their ownership by more than 50 percentage points over their lowest ownership percentage within 
a rolling three-year period. In the event that an ownership change has occurred, or were to occur, utilization of our NOLs would 
be  subject  to  an  annual  limitation  under  Section  382,  determined  by  multiplying  the  value  of  our  equity  at  the  time  of  the 
ownership change by the applicable long-term tax-exempt rate as defined in Section 382, and potentially increased for certain 
gains  recognized  within five  years  after  the  ownership  change  if  we  have a  net built-in  gain in our  assets at  the time of  the 
ownership change. Any unused annual limitation may be carried over to later years. We do not believe that an ownership change 
has occurred as a result of our recent equity offerings or our issuance of shares in connection with various acquisitions. As such, 
Section 382 is not expected to limit our ability to utilize our NOL carryforward or any other tax attribute at December 31, 2018. 
Future ownership changes or future regulatory changes could limit our ability to utilize our NOLs. To the extent we are not able 
to  offset  our  future  income  with  our  NOLs,  this  could  adversely  affect  our  operating  results  and  cash  flows  once  we  attain 
profitability.  

We have substantial indebtedness and may incur substantially more debt. Higher levels of indebtedness make us more 
vulnerable to economic downturns and adverse developments in our business.  

We had approximately $4.2 billion of outstanding aggregate principal indebtedness at December 31, 2018. At December 
31, 2018, commitments from our bank group were $2.0 billion, of which $1.8 billion was unused commitments. We continue to 
review our existing indebtedness, and we may seek to repay, refinance, repurchase, redeem, exchange or otherwise terminate 
our indebtedness. If we do seek to refinance our existing indebtedness, there can be no guarantee that we would be able to 
execute the refinancing on favorable terms or at all. 

As  a  result  of  our  indebtedness,  we  use  a  portion  of  our  cash  flow  to  pay interest,  which  reduces the  amount  we  have 
available to fund our operations and other business activities and could limit our flexibility in planning for or reacting to changes 

23 

 
 
 
 
 
 
 
 
 
 
 
in our business and the industry in which we operate. Our indebtedness under our Credit Facility is at a variable interest rate, 
and so a rise in interest rates will generate greater interest expense.  

We may incur substantially more debt in the future. Our Credit Facility and the indentures governing our senior notes contain 
restrictions on our incurrence of additional indebtedness. These restrictions, however, are subject to a number of qualifications 
and exceptions, and under certain circumstances, we could incur substantial additional indebtedness in compliance with these 
restrictions. Moreover, these restrictions do not prevent us from incurring obligations that do not constitute indebtedness under 
the indentures.  

Any increase in our level of indebtedness could have adverse effects on our financial condition and results of operations, 

including: 

• 

• 

• 

• 

• 

imposing additional cash requirements on us in order to support interest payments, which reduces the amount 
we have available to fund our operations and other business activities; 

increasing the risk that we may default on our debt obligations; 

increasing  our  vulnerability  to  adverse  changes  in  general  economic  and  industry  conditions,  economic 
downturns and adverse developments in our business; 

limiting our ability to sell assets, engage in strategic transactions or obtain additional financing for working 
capital, capital expenditures, general corporate and other purposes; 

limiting  our  flexibility  in  planning  for  or  reacting  to  changes  in  our  business  and  the  industry  in  which  we 
operate; and 

• 

increasing our exposure to a rise in interest rates, which will generate greater interest expense.  

Our ability to meet our debt obligations and to reduce our level of indebtedness depends on our future performance, which 

is affected by general economic conditions and financial, business and other factors, many of which are out of our control. 

If we are unable to comply with the restrictions and covenants in the agreements governing our indebtedness, there 
could be a default under the terms of these agreements, which could result in an acceleration of payment of funds that 
we have borrowed. 

Our ability to meet our debt obligations and other expenses will depend on our future performance, which will be affected 
by financial, business, economic, regulatory and other factors, many of which we are unable to control. If our cash flow is not 
sufficient to service our debt, we may be required to refinance debt, sell assets or sell additional equity on terms that we may 
not find attractive if it may be done at all. If we are unable to generate sufficient cash flow and are otherwise unable to obtain 
funds necessary to meet required payments of principal, premium, if any, and interest, if any, on our indebtedness, or if we 
otherwise fail to comply with the various covenants, including financial and operating covenants, in the agreements governing 
our indebtedness, we could be in default under the terms of the agreements governing such indebtedness. In the event of such 
default: 

• 

• 

the  holders  of  such  indebtedness  could  elect  to  declare  all  the  funds  borrowed  thereunder  to  be  due  and 
payable, together with accrued and unpaid interest; 

the lenders under our Credit Facility could elect to terminate their commitments thereunder and cease making 
further loans; and 

•  we could be forced into bankruptcy or liquidation. 

If our operating performance declines, we may in the future need to obtain waivers under our Credit Facility to avoid being 
in default. If we breach our covenants under our Credit Facility cannot obtain a waiver from the required lenders, we would be 
in default under our Credit Facility, the lenders could exercise their rights, as described above, and we could be forced into 
bankruptcy or liquidation.  

A downgrade in our credit rating could negatively impact our cost of and ability to access capital. 

We receive  debt credit  ratings  from  S&P  Global  Ratings  (“S&P”),  Moody’s  Investors  Service, Inc.  (“Moody’s”)  and Fitch 
Ratings (“Fitch”), which are subject to regular reviews. In August 2017, our long-term debt was assigned a first-time investment 
grade rating by Fitch, and our rating by S&P was raised to an investment grade rating. In determining our ratings, the agencies 
consider a number of qualitative and quantitative factors including, but not limited to: the industry in which we operate, production 
growth opportunities, liquidity, debt levels and asset and reserve mix.  

24 

 
 
 
 
 
 
  
 
 
 
 
 
 
 
 
 
 
 
 
A downgrade in our credit ratings could (i) negatively impact our costs of capital and our ability to effectively execute aspects 
of our strategy, (ii) affect our ability to raise debt in the public debt markets, and the cost of any new debt could be much higher 
than our outstanding debt and (iii) negatively affect our ability to obtain additional financing or the interest rate, fees and other 
terms associated with such additional financing. In September 2017, we elected to enter into an Investment Grade Period under 
our  Credit  Facility,  as  defined  in  Note  10  of  the  Notes  to  Consolidated  Financial  Statements  included  in  “Item  8.  Financial 
Statements and Supplementary Data,” which had the effect of releasing all collateral formerly securing our Credit Facility. If we 
are unable to maintain credit ratings of “Ba2” or better from Moody’s and “BB” or better from S&P, the Investment Grade Period 
will automatically terminate and cause our Credit Facility to once again be secured by a first lien on substantially all of our oil 
and natural gas properties and by a pledge of the equity interests in our subsidiaries. These and other impacts of a downgrade 
in our credit ratings could have a material adverse effect on our business, financial condition and results of operations. 

As of the filing of this report, no additional changes in our credit ratings have occurred; however, we cannot be assured 

that our credit ratings will not be downgraded in the future. 

Our operations expose us to significant costs and liabilities with respect to environmental and operational safety matters. 

We  may  incur  significant  delays,  costs  and  liabilities  as  a  result  of  environmental,  occupational  health  and  safety 
requirements  applicable  to  our  oil  and  natural  gas  exploration,  development  and  production,  and  related  saltwater  disposal 
activities.  These  delays,  costs  and  liabilities  could  arise under  a  wide range  of  federal, state  and local laws  and  regulations 
relating to protection of the environment, occupational health and safety, including regulations and enforcement policies that 
have  tended  to  become  increasingly  strict  over  time.  Failure  to  comply  with  these  laws  and  regulations  may  result  in  the 
assessment of  administrative,  civil  and criminal penalties,  imposition of cleanup  and site  restoration  costs  and liens,  and, in 
some instances, issuance of orders or injunctions limiting or requiring discontinuation of certain operations. In addition, claims 
for damages to persons or property, including natural resources, may result from the environmental, health and safety impacts 
of our operations. 

Strict  as  well  as  joint  and  several  liability  for  a  variety  of  environmental  costs  may  be  imposed  on  us  under  certain 
environmental laws, which could cause us to become liable for the conduct of others or for consequences of our own actions 
that  were  in  compliance  with  all  applicable  laws  at  the  time  those  actions  were  taken.  Costs  stemming  from  environmental 
remediation obligations could be significant and adversely affect our financial condition and results of operations. New laws, 
regulations or enforcement policies could be more stringent and impose unforeseen liabilities or significantly increase compliance 
costs. No assurance can be given that continued compliance with existing or future environmental laws and regulations will not 
result  in  a  curtailment  of  production  or  processing  activities  or  result  in  a  material  increase  in  the  costs  of  production, 
development,  exploration  or  processing  operations.  If  we  are  not  able  to  recover  the  resulting  costs  through  insurance  or 
increased revenues, our production, revenues and results of operations could be adversely affected. 

Our  producing  properties  are  concentrated  in  the  Permian  Basin  of  Southeast  New  Mexico  and  West  Texas,  making  us 
vulnerable  to  risks  associated  with  operating  in  one  major  geographic  area.  In  addition,  substantially  all  of  our  proved 
reserves are attributable to this area.  

Our producing properties are geographically concentrated in the Permian Basin of Southeast New Mexico and West Texas. 
At December 31, 2018, substantially all of our total estimated proved reserves were attributable to properties located in this area. 
As a result of this concentration, we are exposed to the impact of regional supply and demand factors, delays or interruptions of 
production from wells in this area caused by governmental regulation, processing or transportation capacity constraints, including 
current pipeline capacity constraints in the Permian Basin, market limitations, severe weather events, water shortages or other 
drought related conditions or interruption of the processing or transportation of oil or natural gas.  

In  addition  to  the  geographic  concentration  of  our  producing  properties  described  above,  at  December  31,  2018, 
approximately: (i) 57 percent of our proved reserves were attributable to the Delaware Basin that primarily targets the Avalon, 
Bone Spring and Wolfcamp formations; and (iii) 43 percent of our proved reserves were attributable to the Midland Basin that 
primarily targets the Spraberry and Wolfcamp formations. This concentration of assets exposes us to additional risks, such as 
changes in field-wide rules and regulations that could cause us to permanently or temporarily shut-in all of our wells within a 
field. 

We periodically assess our unproved oil and natural gas properties for impairment and could be required to recognize non-
cash charges to earnings of future periods. 

At December 31, 2018, we carried unproved property costs of $6.7 billion. GAAP requires periodic assessment of these 

costs on a project-by-project basis. Our assessment considers: 

• 

• 

• 

future drilling and exploration plans;  

results of exploration activities;  

commodity price outlooks; 

25 

 
 
 
 
 
 
 
 
 
 
 
 
 
• 

• 

planned future sales; and 

expiration of all or a portion of the projects, contracts and permits relevant to such projects.  

Based on our assessments, we may determine that we are unable to fully recover the cost invested in each project, and we 
will recognize non-cash charges to earnings in future periods if such determination is made. For the years ended December 31, 
2018  and  2017,  we  recorded  approximately  $35  million  and  $27  million,  respectively,  of  leasehold  abandonments  primarily 
related to expiring acreage and acreage where we had no future plans to drill, which is included in exploration and abandonments 
expense in our consolidated statements of operations. 

We periodically evaluate our goodwill for impairment and could be required to recognize non-cash charges in the earnings 
of future periods.  

At December 31, 2018, we had goodwill of $2.2 billion. Goodwill is assessed for impairment as of July 1 of each year or 
whenever circumstances indicate that the carrying value of our business may be impaired. If the book value of our reporting unit 
exceeds the estimated fair value of the reporting unit, an impairment charge will occur, which would negatively impact our results 
of operations and net worth. 

Future price declines could result in a reduction in the carrying value of our proved oil and natural gas properties, which 
could adversely affect our results of operations. 

Declines  in  commodity  prices  may  result  in  our  having  to  make  substantial  downward  adjustments  to  the  value  of  our 
estimated proved reserves. If this occurs, or if our estimates of production or economic factors change, accounting rules may 
require us to write-down, as a non-cash charge to earnings, the carrying value of our proved oil and natural gas properties for 
impairments. We are  required  to  perform  impairment  tests on  proved  assets  whenever  events  or changes  in  circumstances 
warrant a review of our proved oil and natural gas properties. To the extent such tests indicate a reduction of the estimated 
useful life or estimated future cash flows of our oil and natural gas properties, the carrying value may not be recoverable and 
therefore  require  a  write-down.  The  primary  factors  that  may  affect  management’s  estimates  of  future  cash  flows  are 
(i) commodity futures prices, (ii) increases or decreases in production and capital costs, (iii) future reserve volume adjustments, 
both positive and negative, to proved reserves and appropriate risk-adjusted probable and possible reserves, (iv) results of future 
drilling  activities  and  (v)  prevailing  market  rates  of  income  and  expenses  from  integrated  assets. We  may  incur  impairment 
charges in the future, which could materially adversely affect our results of operations in the period incurred. We did not incur 
an impairment charge in 2018 and 2017. We recorded impairment charges of $1.5 billion in 2016.  

Our commodity price risk management program may cause us to forego additional future profits or result in us making cash 
payments to our counterparties. 

To reduce our exposure to changes in the prices of commodities, we have entered into and may in the future enter into 
additional commodity price risk management arrangements for a portion of our oil and natural gas production. The agreements 
that we have entered into generally have the effect of providing us with a fixed price for a portion of our expected future oil and 
natural gas production over a fixed period of time. Commodity price risk management arrangements expose us to the risk of 
financial  loss  and  may  limit  our  ability  to  benefit  from  increases  in  commodity  prices  in  some  circumstances,  including  the 
following: 

•  market  prices  may  exceed  the  prices  which  we  are  contracted  to  receive,  resulting  in  our  need  to  make 

significant cash payments to our counterparties; 

• 

• 

there may be a change in the expected differential between the underlying price in a commodity price risk 
management agreement and actual prices received; or 

the counterparty to a commodity price risk management contract may default on its contractual obligations to 
us. 

Our  commodity  price  risk  management  activities  could  have  the  effect  of  reducing  our  net  income and  the  value  of  our 
securities.  At  December  31,  2018,  we  had a  net  derivative asset  of approximately  $695 million.  An  average increase  in  the 
commodity price of $5.00 per barrel of oil and $0.50 per MMBtu of natural gas from the commodity price at December 31, 2018 
would have resulted in a decrease in our net asset of approximately $406 million. We may continue to incur significant gains or 
losses in the future from our commodity price risk management activities to the extent market prices increase or decrease and 
our derivatives contracts remain in place. 

Our identified inventory of drilling locations and recompletion opportunities are scheduled over several future years, making 
them susceptible to uncertainties that could materially alter the occurrence or timing of their drilling. 

26 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
We have identified and scheduled the drilling of certain locations as an estimation of our future multi-year development 
activities on our existing acreage. These identified locations represent a significant part of our growth strategy. Our ability to drill 
and develop these locations depends on a number of uncertainties, including those described elsewhere in these risk factors. 
Because of these and other potential uncertainties, we may never drill the potential locations we have identified or produce oil 
or natural gas from these or any other potential locations. As such, our actual development activities may materially differ from 
those presently identified, which could adversely affect our production, reserves, revenues and results of operations. 

Unless we replace our oil and natural gas reserves, our reserves and production will decline, which would adversely affect 
our cash flow, our ability to raise capital and the value of our securities. 

Unless we conduct successful development and exploration activities or acquire properties containing proved reserves, our 
proved reserves will decline as those reserves are produced. Producing oil and natural gas reservoirs generally are characterized 
by declining production rates that vary depending upon reservoir characteristics and other factors. Our future oil and natural gas 
reserves and production, and therefore our cash flow and results of operations, are highly dependent on our success in efficiently 
developing and exploiting our current reserves and economically finding or acquiring additional recoverable reserves. The value 
of our securities and our ability to raise capital will be adversely impacted if we are not able to replace our reserves that are 
depleted by production or replace our declining production with new production. We may not be able to develop, exploit, find or 
acquire sufficient additional reserves or replace our current and future production. 

The Standardized Measure and PV-10 of our estimated reserves are not accurate estimates of the current fair value of 
our estimated proved oil and natural gas reserves. 

Standardized Measure is a reporting convention that provides a common basis for comparing oil and natural gas companies 
subject to the rules and regulations of the SEC. Our non-GAAP financial measure, PV-10, is a similar reporting convention that 
we have disclosed in this report. Both measures require the use of operating and development costs prevailing as of the date of 
computation.  Consequently,  they  will  not  reflect  the  prices ordinarily  received  or  that  will  be  received  for  oil and  natural  gas 
production because of varying market conditions, nor may it reflect the actual costs that will be required to produce or develop 
the oil and natural gas properties. Accordingly, estimates included herein of future net cash flows may be materially different 
from the future net cash flows that are ultimately received. In addition, the 10 percent discount factor, which is required by the 
rules and regulations of the SEC to be used in calculating discounted future net cash flows for reporting purposes, may not be 
the most appropriate discount factor based on interest rates in effect from time to time and risks associated with our company 
or the oil and natural gas industry in general. Therefore, Standardized Measure and PV-10 included in this report should not be 
construed as accurate estimates of the current fair value of our proved reserves.  

Our reserve estimates and our computation of future net cash flows at December 31, 2018 are based on SEC pricing of (i) 
$62.04 per Bbl WTI posted oil price and (ii) $3.10 per MMBtu Henry Hub spot natural gas price, adjusted for location and quality 
by property. The SEC pricing for reserves as of December 31, 2018 is higher than the NYMEX oil price of $55.59 per Bbl at 
February 15, 2019 and higher than the NYMEX natural gas price of $2.63 per MMBtu at February 15, 2019. If average oil prices 
were $5.00 per barrel lower than the average price we used, our PV-10 at December 31, 2018 would have decreased from 
$17.9 billion to $16.3 billion. If average natural gas prices were $0.50 per MMBtu lower than the average price we used, our PV-
10 at December 31, 2018 would have decreased from $17.9 billion to $17.2 billion. Any adjustments to the estimates of proved 
reserves or decreases in the price of our commodities may decrease the value of our securities. 

We may be unable to make attractive acquisitions or successfully integrate acquired companies or assets, and any inability 
to do so may disrupt our business and hinder our ability to grow. 

One aspect of our business strategy calls for acquisitions of businesses or assets that complement or expand our current 
business. We may not be able to identify attractive acquisition opportunities, including acreage trades. Even if we do identify 
attractive candidates, pursuing such acquisitions may be distracting to management and costly to the Company. We may not be 
able to complete the acquisition of them or do so on commercially acceptable terms. 

In addition, our Credit Facility and the indentures governing our senior notes impose certain limitations on our ability to enter 
into mergers or business combination transactions. Our Credit Facility and the indentures governing our senior notes also limit 
our ability to incur certain indebtedness, which could indirectly limit our ability to engage in acquisitions of businesses or assets. 
If we desire to engage in an acquisition that is otherwise prohibited by our Credit Facility or the indentures governing our senior 
notes,  we  will  be  required  to  seek  the  consent  of  our  lenders  or  the  holders  of  the  senior  notes  in  accordance  with  the 
requirements of our Credit Facility or the indentures, which consent may be withheld by the lenders under our Credit Facility or 
such holders of senior notes at their sole discretion. 

If we acquire another business or assets, we could have difficulty integrating its operations, systems, management and 
other personnel and technology with our own. These difficulties could disrupt our ongoing business, distract our management 
and employees, increase our expenses and adversely affect our results of operations. In addition, we may incur additional debt 
or issue additional equity to pay for any future acquisitions, subject to the limitations described above. 

27 

 
 
 
 
 
 
 
 
 
 
 
Any acquisition we complete is subject to substantial risks that could adversely affect our business, including the risk that 
our acquisitions may prove to be worth less than what we paid because of uncertainties in evaluating recoverable reserves 
and could expose us to potentially significant liabilities. 

We obtained a significant portion of our current reserve base through acquisitions of producing properties and undeveloped 
acreage. We expect that acquisitions, including acreage trades, will continue to contribute to our future growth. In connection 
with  these  and  potential  future  acquisitions,  we  are  often  only  able  to  perform  limited  due  diligence.  The  success  of  any 
acquisition involves potential risks, including among other things: 

• 

• 

• 

• 

• 

the inability to estimate accurately the costs to develop the reserves, recoverable volumes of reserves, rates 
of future production and future net cash flows attainable from the reserves; 

the assumption of unknown liabilities, including environmental liabilities, and losses or costs for which we are 
not indemnified or for which the indemnity we receive is inadequate; 

the effect on our liquidity or financial leverage of using available cash or debt to finance acquisitions; 

the diversion of management’s attention from other business concerns; and 

an inability to hire, train or retain qualified personnel to manage and operate our growing business and assets. 

Successful acquisitions of oil and natural gas properties require an assessment of a number of factors, including estimates 
of recoverable reserves, the timing of recovering reserves, exploration potential, future commodity prices, operating costs and 
potential environmental, regulatory and other liabilities. Such assessments are inexact, and we cannot make these assessments 
with a high degree of accuracy. In connection with our assessments, we perform a review of the acquired properties that we 
believe to be generally consistent with industry practices. However, such a review will not reveal all existing or potential problems. 
In addition, our review may not permit us to become sufficiently familiar with the properties to fully assess their deficiencies and 
capabilities. We do not inspect every well. Even when we inspect a well, we do not always discover structural, subsurface and 
environmental problems that may exist or arise. 

There may be threatened, contemplated, asserted or other claims against the acquired assets related to environmental, 
title, regulatory, tax, contract, litigation or other matters of which we are unaware, which could materially and adversely affect 
our production, revenues and results of operations. We are sometimes able to obtain contractual indemnification for preclosing 
liabilities,  including  environmental  liabilities,  but  we  generally  acquire  interests  in  properties  on  an  “as  is”  basis  with  limited 
remedies for breaches of representations and warranties. In addition, even when we are able to obtain such indemnification 
from the sellers, these indemnification obligations usually expire over time and expose us to potential unindemnified liabilities, 
which could materially adversely affect our production, revenues and results of operations. 

Shortages of oilfield equipment, services and qualified personnel could delay our drilling program and increase the prices 
we pay to obtain such equipment, services and personnel. 

The  demand  for  qualified  and  experienced  field  personnel  to  drill  wells  and  conduct  field  operations,  geologists, 
geophysicists, engineers and other professionals in the oil and natural gas industry can fluctuate significantly, often in correlation 
with commodity prices, causing periodic labor shortages. Historically, there have been shortages of drilling and workover rigs, 
pipe and other oilfield equipment as demand for rigs and equipment has increased along with the number of wells being drilled. 
These  factors  also  cause  significant  increases  in  costs  for  equipment,  services  and  personnel.  Higher  commodity  prices 
generally  stimulate  demand  and  result  in  increased  prices  for  drilling  and  workover  rigs,  crews  and  associated  supplies, 
equipment and services. It is beyond our control and ability to predict whether these conditions will exist in the future and, if so, 
what their timing and duration will be. These types of shortages or price increases would decrease our profit margin, cash flow 
and operating results, or restrict our ability to drill the wells and conduct the operations which we currently have planned and 
budgeted or which we may plan in the future.  

Our exploration and development drilling may not result in commercially productive reserves. 

Drilling activities are subject to many risks, including the risk that commercially productive reservoirs will not be encountered. 
New wells that we drill may not be productive, or we may not recover all or any portion of our investment in such wells. The 
seismic data and other technologies we use do not allow us to know conclusively prior to drilling a well that oil or natural gas is 
present or may be produced economically. Drilling for oil and natural gas often involves unprofitable results, not only from dry 
holes but also from wells that are productive but do not produce sufficient net reserves to return a profit at then realized prices 
after deducting drilling, operating and other costs. The cost of drilling, completing and operating a well is often uncertain, and 
cost factors can adversely affect the economics of a project. Further, our drilling operations may be curtailed, delayed or canceled 
as a result of numerous factors, including: 

• 

unexpected drilling conditions; 

28 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
  
• 

• 

• 

• 

• 

• 

• 

• 

risks associated with drilling horizontal wells and extended lateral lengths, such as deviating from the desired 
drilling zone or not running casing or tools consistently through the wellbore, particularly as lateral lengths get 
longer; 

pressure or irregularities in formations; 

equipment failures or accidents; 

construction delays; 

fracture stimulation accidents or failures; 

adverse weather conditions;  

compliance with environmental and other governmental or contractual requirements; and 

increases  in  the cost  of,  or shortages  or delays in  the  availability  of,  electricity,  water,  supplies, materials, 
drilling or workover rigs, equipment and services. 

We may incur substantial losses and be subject to substantial liability claims as a result of our oil and natural gas operations. 
In addition, we may not be insured for, or our insurance may be inadequate to protect us against, these risks. 

We are not insured against all risks. Losses and liabilities arising from uninsured and underinsured events could materially 
and adversely affect our business, financial condition or results of operations. Our oil and natural gas exploration and production 
activities, including well stimulation and completion activities such as hydraulic fracturing, are subject to all of the operating risks 
associated with drilling for and producing oil and natural gas, including the possibility of: 

• 

environmental hazards, such as uncontrollable flows of oil, natural gas, saltwater, well fluids, toxic gas or other 
pollution into the environment, including groundwater contamination; 

• 

abnormally pressured or structured formations; 

•  mechanical difficulties, such as stuck oilfield drilling and service tools and casing collapse; 

• 

• 

• 

blowouts, cratering, fires, explosions and ruptures of pipelines; 

personal injuries and death; and 

natural disasters. 

Any of these risks could adversely affect our ability to conduct operations or result in substantial losses to us as a result of: 

• 

• 

• 

• 

• 

• 

• 

• 

damage to and destruction of property and equipment; 

damage to natural resources due to underground migration of hydraulic fracturing fluids; 

pollution and other environmental damage, including spillage or mishandling of recovered hydraulic fracturing 
fluids; 

regulatory investigations and penalties; 

loss of well location, acreage, expected production and related reserves; 

suspension or delay of our operations;  

substantial liability claims; and 

repair and remediation costs. 

We may elect not to obtain insurance if we believe that the cost of available insurance is excessive relative to the risks 
presented. In addition, pollution and environmental risks generally are not fully insurable, and we do not insure for business 
interruption of the loss of a well. The occurrence of an event that is not covered or not fully covered by insurance could have a 
material adverse effect on our production, revenues and results of operations.

Competition in the oil and natural gas industry is intense, making it more difficult for us to acquire properties, market oil and 
natural gas and secure trained personnel. 

We operate in a highly competitive environment for acquiring properties, marketing oil and natural gas and securing trained 
personnel. Some of our competitors possess and employ financial, technical and personnel resources substantially greater than 
ours,  which can be  particularly  important  in  the  areas in  which  we  operate.  Those  companies  may  be able  to  pay  more  for 
productive oil and natural gas properties and exploratory prospects and to evaluate, bid for and purchase a greater number of 
properties and prospects than our financial or personnel resources permit. In addition, those companies may be able to offer 
better compensation packages to attract and retain qualified personnel than we are able to offer. The cost and other challenges 
to attract and retain qualified personnel may increase substantially in the future. Our ability to acquire additional prospects and 
to find and develop reserves in the future will depend on our ability to evaluate and select suitable properties and to consummate 
transactions in a highly competitive environment. Also, there is substantial competition for capital available for investment in the 
oil  and  natural  gas  industry.  We  may  not  be  able  to  compete  successfully  in  the  future  in  acquiring  prospective  reserves, 
developing reserves, marketing hydrocarbons, attracting and retaining quality personnel and raising additional capital. Our failure 
to acquire properties, market oil and natural gas, secure trained personnel and adequately compensate personnel could have a 
material adverse effect on our production, revenues and results of operations. 

Market conditions or operational impediments may hinder our access to oil and natural gas markets or delay our production. 

Market conditions or the unavailability of satisfactory oil and natural gas processing or transportation arrangements may 
hinder our access to oil and natural gas markets or delay our production. The availability of a ready market for our oil and natural 
gas production depends on a number of factors, including the demand for and supply of oil and natural gas, the proximity of 
reserves to pipelines and storage facilities, gathering systems and other transportation, processing, fractionation, refining and 
export facilities, competition for such facilities and the inability of such facilities to gather, transport or process our production 
due  to shutdowns  or  curtailments  arising  from mechanical,  operational  or  weather  related  matters, including  hurricanes  and 
other severe weather conditions. Our ability to market our production depends in substantial part on the availability and capacity 
of  gathering,  storage  and  transportation  systems,  pipelines  and  processing  facilities  owned  and  operated  by  third  parties. 
Throughout 2018, concerns emerged that Permian oil supply would exceed pipeline capacity. Our ability to market our production 
may be impacted if such constraints continue or become worse in the future. Our failure to obtain such services on acceptable 
terms or the failure of counterparties to perform under certain of our transportation or marketing arrangements could have a 
material adverse effect on our business, financial condition and results of operations. We may be required to shut in or otherwise 
curtail production from wells due to lack of a market or inadequacy or unavailability of oil or natural gas pipeline or gathering, 
storage, transportation or processing capacity and fractionation, refining or export facilities. If that were to occur, then we would 
be unable to realize revenue from those wells until suitable arrangements were made to market our production. 

We are subject to complex federal, state, local and other laws and regulations that could adversely affect the cost, timing, 
manner or feasibility of conducting our operations or that may subject us to fines or penalties for any failure to comply. 

Our oil and natural gas exploration, development and production, and related saltwater disposal operations are subject to 
complex and stringent laws and regulations. In order to conduct our operations in compliance with these laws and regulations, 
we must obtain and maintain numerous permits, approvals and certificates from various federal, state, local and governmental 
authorities. We may incur substantial costs and experience delays in order to maintain compliance with these existing laws and 
regulations.  If  we  fail  to  comply  with  the  existing  laws  and  regulations,  we  may  incur  additional  costs,  including  fines  and 
penalties, in order to come back into compliance. In addition, our costs of compliance may increase or our operations may be 
otherwise  adversely  affected  if  existing  laws  and  regulations  are  revised  or  reinterpreted  or  if  the  government  agencies 
responsible for enforcing certain existing laws and regulations applicable to us change their priorities or policies, or if new laws 
and  regulations  become  applicable  to  our  operations.  These  and  other  costs  could  have  a  material  adverse  effect  on  our 
production, revenues and results of operations. 

The implementation of derivatives legislation adopted by Congress could have an adverse effect on our ability to use 
derivative  instruments  to  reduce  the  effect  of  commodity  price,  interest  rate  and  other  risks  associated  with  our 
business.  

Congress adopted comprehensive financial reform legislation that establishes federal oversight and regulation of the over-
the-counter derivatives market and entities, including us, which participate in that market. This legislation, known as the Dodd-
Frank Wall Street Reform and Consumer Protection Act (the “Act”), became law on July 21, 2010 and requires the Commodity 
Futures Trading Commission (the “CFTC”) and the SEC to promulgate rules and regulations implementing the Act. Although the 
CFTC has finalized certain regulations, others remain to be finalized or implemented, and it is not possible at this time to predict 
when this will be accomplished.  

In October 2011, the CFTC issued regulations to set position limits for certain futures and option contracts in the major 
energy markets and for swaps that are their economic equivalents; however this initial position limits rule was vacated by the 
U.S. District Court for the District of Columbia in September 2012. The CFTC has subsequently issued proposals for new rules 
that would place position limits on certain core futures contracts and equivalent swap contracts for or linked to certain physical 

30 

 
 
 
 
 
 
 
 
 
 
commodities, subject to certain exceptions for bona fide hedging transactions. As these new position limit rules are not yet final, 
the impact of those provisions on us is uncertain at this time.  

The  CFTC  has  designated  certain  interest  rate  swaps  and  credit  default  swaps  subject  to  mandatory  clearing  and  the 
associated rules also will require us, in connection with covered derivative activities, to comply with clearing and trade-execution 
requirements or take steps to qualify for an exemption to such requirements. The CFTC has not yet proposed rules designating 
any other classes of swaps, including physical commodity swaps, for mandatory clearing. Although we expect to qualify for the 
end-user exception from the mandatory clearing requirements for swaps entered to hedge our commercial risks, the application 
of the mandatory clearing and trade execution requirements to other market participants, such as swap dealers, may change 
the cost and availability of the swaps that we use for hedging. If our swaps do not qualify for the commercial end-user exception 
from mandatory clearing, or if the cost of entering into uncleared swaps becomes prohibitive, we may be required to clear such 
transactions  or  our  ability  to  hedge may  be impacted.  The ultimate  effect of  the  rules and  any  additional  regulations  on  our 
business is uncertain at this time. 

In addition, certain banking regulators and the CFTC have adopted final rules establishing minimum margin requirements 
for  uncleared  swaps.  Although  we  expect  to  be  exempt  from  such  requirements  for  the  mandatory  exchange  of  margin  for 
uncleared swaps, the application of such requirements to other market participants, such as swap dealers, may change the cost 
and availability of the swaps that we use for hedging. Further, if we do not qualify for an exemption and are required to post 
collateral  for  our  swaps,  it  could  reduce  our  liquidity  and  cash  available  for  capital  expenditures  and  our  ability  to  manage 
commodity price volatility and the volatility in cash flows.  

The full impact of the Act and related regulatory requirements upon our business will not be known until the regulations are 
implemented and the market for derivatives contracts has adjusted. When fully implemented, the Act and any new regulations 
could increase the operational and transactional cost of derivatives contracts, reduce the availability of derivatives to protect 
against risks we encounter, reduce our ability to monetize and restructure our existing derivatives contracts, impact commodity 
prices and affect the number and/or creditworthiness of available counterparties. If we reduce our use of derivatives as a result 
of the Act and regulations implementing the Act, our results of operations may become more volatile and our cash flows may be 
less predictable, which could adversely affect our ability to plan for and fund capital expenditures. Any of these consequences 
could have a material adverse effect on us, our financial condition and our results of operations. 

The loss of our chief executive officer or other key personnel could negatively impact our ability to execute our business 
strategy. 

We depend, and will continue to depend in the foreseeable future, on the services of our chief executive officer, Timothy A. 
Leach,  and  other  officers  and  key  employees  who  have  extensive  experience  and  expertise  in  evaluating  and  analyzing 
producing  oil  and  natural  gas  properties  and  drilling  prospects,  maximizing  production  from  oil  and  natural  gas  properties, 
marketing oil and natural gas production, and developing and executing acquisition, financing and hedging strategies. Our ability 
to hire and retain our officers and key employees is important to our continued success and growth. The unexpected loss of the 
services of one or more of these individuals could negatively impact our ability to execute our business strategy. 

Because we do not operate and therefore control the development of certain of the properties in which we own interests, we 
may not be able to produce economic quantities of oil and natural gas in a timely manner. 

At December 31, 2018, approximately 6 percent of our proved reserves were attributable to properties for which we were 
not the operator. As a result, the success and timing of drilling and development activities on properties operated by others 
depend upon a number of factors that are beyond our control, including: 

• 

• 

• 

• 

• 

the nature and timing of drilling and operational activities controlled by others; 

the timing and amount of the operators’ capital expenditures; 

the operators’ expertise and financial resources; 

the approval of other participants in such properties; and 

the selection and application of suitable technology. 

If drilling and development activities are not conducted on these properties or are not conducted as we expect, we may be 
unable to increase our production or offset normal production declines or we will be required to write-off the reserves attributable 
to such properties, which may adversely affect our production, revenues and results of operations. 

We do not control certain of the entities in which we own equity interests. 

Certain of the entities in which we own equity interests are managed by their respective governing bodies. As a result, our ability 
to influence decisions with respect to the operation of such entities varies depending on the amount of control we exercise under the 

31 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
applicable governing agreement, including with respect to cash distributions, capital calls, capital expenditures and the incurrence of 
additional indebtedness.  

A terrorist or cyber attack or armed conflict could harm our business by decreasing our revenues and increasing our costs. 

Terrorist activities, anti-terrorist efforts, cyber attacks and other armed conflicts involving the United States may adversely 
affect the United States and global economies and could prevent us from meeting our financial and other obligations. If any of 
these events occur or escalate, the resulting political instability and societal disruption could reduce overall demand for oil and 
natural gas, potentially putting downward pressure on demand for our production and causing a reduction in our revenue. Oil 
and natural gas related facilities could be direct targets of terrorist attacks, and our operations could be adversely impacted if 
significant  infrastructure  or  facilities  used  for  the  production,  transportation,  processing  or  marketing  of  oil  and  natural  gas 
production are destroyed or damaged. Additionally, as an oil and natural gas producer, we constantly face various cybersecurity 
threats, including threats to gain unauthorized access to sensitive information or to render data or systems unusable, and there 
can be no assurance that our implementation of various procedures and controls to monitor and mitigate security threats will be 
sufficient to prevent security breaches from occurring. Costs for insurance, recovery, remediation, potential litigation and other 
security measures may increase as a result of these threats, and some insurance coverage may become more difficult to obtain, 
if available at all. 

Our reliance on information technology, including those hosted by third parties, exposes us to cyber security risks 
that could affect our business, financial condition or reputation and increase compliance challenges. 

We rely extensively on information technology systems, including internet sites, computer software, data hosting facilities 
and  other  hardware  and  platforms,  some  of  which  are  hosted  by  third  parties,  to  assist  in  conducting  our  business.  Our 
information technology systems, as well as those of third parties we use in our operations, may be vulnerable to a variety of 
evolving cybersecurity risks, such as those involving unauthorized access, denial-of-service attacks, malicious software, data 
privacy breaches by employees, insiders or others with authorized access, cyber or phishing-attacks, ransomware, malware, 
social engineering, physical breaches or other actions. These cybersecurity threat actors are becoming more sophisticated and 
coordinated  in  their  attempts  to  access  the  company's  information  technology  systems  and  data,  including  the  information 
technology systems of cloud providers and third parties with which the company conducts business. 

Although we have implemented information technology controls and systems that are designed to protect information and 
mitigate the risk of data loss and other cybersecurity risks, such measures cannot entirely eliminate cybersecurity threats, and 
the enhanced controls we have installed may be breached. If our information technology systems cease to function properly or 
our  cybersecurity  is  breached,  we  could  suffer  disruptions  to  our  normal  operations  which  may  include  drilling,  completion, 
production and corporate functions. A cyber attack involving our information systems and related infrastructure, or that of our 
business associates, could negatively impact our operations in a variety of ways, including, but not limited to, the following: 

•  Unauthorized access to seismic data, reserves information, strategic information, or other sensitive or proprietary 

information could have a negative impact on our ability to compete for oil and natural gas resources;  

•  Data corruption, communication interruption, or other operational disruption during drilling activities could result in 

failure to reach the intended target or a drilling incident;  

•  Data corruption or operational disruptions of production-related infrastructure could result in a loss of production, 

or accidental discharge;  

•  A cyber attack on a vendor or service provider could result in supply chain disruptions which could delay or halt 

our major development projects;  

•  A  cyber  attack  on  third-party  gathering,  pipeline,  or  rail  transportation  systems  could  delay  or  prevent  us  from 

transporting and marketing our production, resulting in a loss of revenues; 

•  A cyber attack involving commodities exchanges or financial institutions could slow or halt commodities trading, 
thus preventing us from marketing our production or engaging in hedging activities, resulting in a loss of revenues;  

•  A cyber attack which halts activities at a power generation facility or refinery using natural gas as feed stock could 
have a significant impact on the natural gas market, resulting in reduced demand for our production, lower natural 
gas prices, and reduced revenues;  

•  A cyber attack on a communications network or power grid could cause operational disruption resulting in loss of 

revenues;  

•  A  cyber  attack  on  our  automated  and  surveillance  systems  could  cause  a  loss  in  production  and  potential 

environmental hazards; 

32 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
•  A deliberate corruption of our financial or operating data could result in events of non-compliance which could then 

lead to regulatory fines or penalties; and 

•  A cyber attack resulting in the loss or disclosure of, or damage to, our or any of our customer’s or supplier’s data 
or confidential information could harm our business by damaging our reputation, subjecting us to potential financial 
or legal liability, and requiring us to incur significant costs, including costs to repair or restore our systems and data 
or to take other remedial steps.  

All of the above could negatively impact our operational and financial results. Additionally, certain cyber incidents, such as 
surveillance, may remain undetected for an extended period. As cyber threats continue to evolve, we may be required to expend 
significant additional resources to continue to modify or enhance our protective measures or to investigate and remediate any 
information  security  vulnerabilities.  Additionally,  the  growth  of  cyber  attacks  has  resulted  in  evolving  legal  and  compliance 
matters which impose significant costs that are likely to increase over time.

Risks Related to Our Common Stock 

Our certificate of incorporation, our bylaws and Delaware law contain provisions that could discourage acquisition bids or 
merger proposals, which may adversely affect the market price of our common stock. 

Our certificate of incorporation authorizes our board of directors to issue preferred stock without stockholder approval. If our 
board  of  directors  elects  to  issue  preferred  stock,  it  could be  more  difficult  for a  third  party  to  acquire  us.  In  addition,  some 
provisions of our certificate of incorporation, our bylaws and Delaware law could make it more difficult for a third party to acquire 
control of us, even if the change of control would be beneficial to our stockholders, including: 

• 

• 

• 

• 

the organization of our board of directors as a classified board, which allows no more than approximately one-
third of our directors to be elected each year; 

stockholders cannot remove directors from our board of directors except for cause and then only by the holders 
of not less than 66 2/3 percent of the voting power of all outstanding voting stock; 

the prohibition of stockholder action by written consent; and 

limitations on the ability of our stockholders to call special meetings and establish advance notice provisions 
for stockholder proposals and nominations for elections to the board of directors to be acted upon at meetings 
of stockholders. 

The payment of dividends will be at the discretion of our board of directors. 

While the Company declared a quarterly dividend of $0.125 per share in the first quarter of 2019 and intends to continue to 
pay a dividend in the future, the payment and amount of future dividend payments, if any, are subject to declaration by our board 
of directors. Such payments will depend on various factors, including actual results of operations, liquidity and financial condition, 
net cash provided by operating activities, restrictions imposed by applicable law, our taxable income, our operating expenses 
and  other  factors  our  board  of  directors  deems  relevant.  Covenants  contained  in  our  Credit  Agreement  and  the  indentures 
governing our senior notes could limit the payment of dividends. The Company is under no obligation to make dividend payments 
on our common stock and may cease such payments at any time in the future. 

The availability of shares for sale in the future could reduce the market price of our common stock. 

In the future, we may acquire interests in other companies by using a combination of cash and our common stock or just 
our common stock. We may also issue securities to raise cash for acquisitions. We may also issue securities convertible into, 
or exchangeable for, or that represent the right to receive, our common stock. Any of these events may dilute your ownership 
interest in our Company, reduce our earnings per share and have an adverse impact on the price of our common stock. 

In addition, sales of a substantial amount of our common stock in the public market, or the perception that these sales may 
occur, could reduce the market price of our common stock. This could also impair our ability to raise additional capital through 
the sale of our securities.

Our Oil and Natural Gas Reserves 

The estimates of our proved reserves at December 31, 2018, all of which were located in the United States, were based on 
evaluations  prepared  by  the  independent  petroleum  engineering  firms  of  Cawley,  Gillespie  &  Associates,  Inc.  (“CGA”)  and 
Netherland, Sewell & Associates, Inc. (“NSAI”) (collectively, our “external engineers”). Reserves were estimated in accordance 
with guidelines established by the SEC and the Financial Accounting Standards Board (the “FASB”).  

Internal controls. Our proved reserves are estimated at the property level by external engineers and compiled for reporting 
purposes by our corporate reservoir engineering staff. We maintain our internal evaluations of our reserves in a secure reserve 
engineering  database.  The  corporate  reservoir  engineering  staff  interact  with  our  internal  staff  of  petroleum  engineers, 
geoscience professionals and land professionals in each of our operating areas and with accounting and marketing employees 
to obtain the necessary data for the reserves estimation process. Reserves are reviewed and approved internally by members 
of our senior management and the health, safety, environment and reserves committee, a committee of our board of directors.  

34 

 
 
 
 
 
 
 
 
 
 
 
 
  
 
  
 
 
  
 
 
Our internal professional staff works closely with our external engineers to ensure the integrity, accuracy and timeliness of 
data that is furnished to them for their reserve estimation process. All of the reserve information maintained in our secure reserve 
engineering  database  is  provided  to  the  external  engineers.  In  addition,  other  pertinent  data  is  provided  such  as  seismic 
information,  geologic  maps,  well  logs,  production  tests,  material  balance  calculations,  well  performance  data,  operating 
procedures and relevant economic criteria. We make available all information requested, including our pertinent personnel, to 
the external engineers as part of their preparation of our reserves.

Extensions  and  discoveries.  Extensions  and  discoveries  of  approximately  226  MMBoe  are  primarily  the  result  of  our 
continued  success  from  our  horizontal  drilling  programs  in  our  operating  areas.  Proved  developed  reserves  increased 
approximately 87 MMBoe due to our drilling activity in 2018, and based upon this activity, we added approximately 139 MMBoe 
of new proved undeveloped reserves.  

Purchases  and  sales  of  minerals-in-place.  Our  purchases  of  minerals-in-place  were  primarily  the  result  of  the  RSP 
Acquisition in July  2018  which  added  approximately  275  MMBoe.  The  remainder  of  the purchases  of  minerals-in-place  was 
primarily the result of certain acquisitions and nonmonetary transactions during 2018, which added approximately 25 MMBoe in 
the  Midland  Basin  and  8  MMBoe  in  the  Delaware  Basin.  Our  sales  of  minerals-in-place  were  primarily  the  result  of  various 
divestitures and nonmonetary transactions during 2018. 

Revisions  of  previous  estimates.  Revisions  of  previous  estimates  are  primarily  composed  of  (i)  77  MMBoe  of  negative 
revisions due to proved undeveloped reserves reclassified to unproved, (ii) 15 MMBoe of net negative performance and other 
revisions and (iii) 18 MMBoe of positive price revisions. Our proved reserves at December 31, 2018 were determined using the 
SEC  prices  of  $62.04  per  Bbl  of  oil  for  WTI  and  $3.10  per  MMBtu  of  natural  gas  for  Henry  Hub  spot,  as  compared  to 
corresponding prices of $47.79 per Bbl of oil and $2.98 per MMBtu of natural gas at December 31, 2017. As we continue to 
transition our development program to large-scale projects and evaluate and analyze our producing oil and natural gas properties 
and drilling prospects, certain properties were no longer expected to be developed within five years of the date of their initial 
recognition and were removed from our current drilling plans. This includes certain properties with a lower liquids content and 
certain non-operated properties that we reclassified due to the uncertainty regarding the timing of development. Net negative

performance  and  revisions  primarily  related  to  27  MMBoe  of  downward  revisions  to  certain  proved  developed  producing 
properties in our Yeso field, partially offset by other positive performance revisions. 

Proved  undeveloped  reserves.    At  December  31,  2018,  we  had  approximately  363  MMBoe  of  proved  undeveloped 

reserves as compared to 252 MMBoe at December 31, 2017.

Extensions and discoveries. Extensions and discoveries of approximately 139 MMBoe are primarily the result of new proved 

undeveloped locations that were added as a result of our exploration program during 2018.  

Purchases  and  sales  of  minerals-in-place.  Our  purchases  of  minerals-in-place  were  primarily  the  result  of  the  RSP 
Acquisition in July  2018  which  added  approximately  103  MMBoe.  The  remainder  of  the purchases  of  minerals-in-place  was 
primarily the result of certain acquisitions and nonmonetary transactions during 2018 which added approximately 7 MMBoe in 
the  Midland  Basin  and  3  MMBoe  in  the  Delaware  Basin.  Our  sales  of  minerals-in-place  were  primarily  the  result  of  certain 
divestitures and nonmonetary transactions in the Midland Basin during 2018. 

Revisions of previous estimates. Net negative revisions of previous estimates of approximately 69 MMBoe are primarily 
attributable to 77 MMBoe of negative revisions primarily due to proved undeveloped reserves reclassified to unproved, partially 
offset by approximately 8 MMBoe of net positive revisions. As we continue to transition our development program to large-scale 
projects and evaluate and analyze our producing oil and natural gas properties and drilling prospects, certain properties were 
no longer expected to be developed within five years of the date of their initial recognition and were removed from our current 
drilling plans. This includes certain properties with a lower liquids content and certain non-operated properties that we reclassified 
due to the uncertainty regarding the timing of development.  

Conversion to proved developed reserves. The following table sets forth proved undeveloped reserves converted to proved 
developed  reserves  and  the  associated  investment  required  to  convert  proved  undeveloped  reserves  to  proved  developed 
reserves during the year ended December 31, 2018:

(a)  Of this amount, approximately $115 million was spent in 2018 on proved undeveloped reserves that were not converted to 
proved developed reserves by December 31, 2018. In addition, this amount does not include 10 MMBoe and $88 million of 
costs incurred to convert proved undeveloped reserves to proved developed reserves acquired in the RSP Acquisition.   

____________________________________________________________________________________________________ 

Historically, our drilling programs were substantially funded from our cash flows from operations and borrowings from our 
Credit Facility. Based on our current expectations over the next five years of our cash flows and drilling programs, which includes 
drilling of proved undeveloped and unproved locations, we believe that we can continue to substantially fund our drilling activities 
from our cash flow and with borrowings from our Credit Facility, if needed. Based on SEC pricing as of December 31, 2018, 
estimated  future  development  costs  required  for  the  development  of  proved  undeveloped  reserves  are  projected  to  be 
approximately $3.3 billion over the next five years.

undivided interests and have multiple net acreage expiration dates within the same tract of land. Expirations of net acres 
are shown in the year they occur, while the expirations of gross acres are shown in the final year of net acre expiration. 

At December 31, 2018, we had approximately 95,000 gross and 81,000 net acres subject to a continuous development 
clause or similar drilling commitments. Historically, we have not experienced material expiration of acres due to non-compliance 
and we do not anticipate any material expirations during 2019 or any future periods.

Drilling Activities 

For summary tables that set forth information with respect to wells drilled and completed for the years ended December 31, 

2018, 2017 and 2016, see “Item 1. Business—Drilling Activities.” 

Our Production, Prices and Expenses 

For a summary table that sets forth information concerning our production and operating data from operations for the years 

ended December 31, 2018, 2017 and 2016, see “Item 1. Business—Our Production, Prices and Expenses.” 

Productive Wells 

For a summary table that sets forth the number of productive oil and natural gas wells on our properties at December 31, 

2018, 2017 and 2016, see “Item 1. Business—Productive Wells.” 

Title to Our Properties 

As is customary in the oil and natural gas industry, we initially conduct only a cursory review of the title to our properties on 
which we do not have proved reserves. Prior to the commencement of drilling operations on those properties, we conduct a 
more thorough title examination and perform curative work with respect to significant defects. To the extent title opinions or other 
investigations reflect defects affecting those properties, we are typically responsible for curing any such defects at our expense. 
We  generally  will  not  commence  drilling  operations  on  a  property  until  we  have  cured  known  material  title  defects  on  such 
property. We have reviewed the title to substantially all of our producing properties and believe that we have satisfactory title to 
our producing properties in accordance with standards generally accepted in the oil and natural gas industry. Prior to completing 
an  acquisition  of  producing  oil  and  natural  gas  properties,  we  perform  title  reviews  on  the  most  significant  properties,  and 
depending on the materiality of properties, we may obtain a title opinion or review or update previously obtained title opinions. 
Our oil and natural gas properties are subject to customary royalty and other interests, liens for current taxes and other burdens 
that we believe do not materially interfere with the use or affect our carrying value of the properties. 

Item 3.  Legal Proceedings 

We are a party to proceedings and claims incidental to our business. While many of these other matters involve inherent 
uncertainty, we believe that the liability, if any, ultimately incurred with respect to such other proceedings and claims will not 
have a material adverse effect on our consolidated financial position as a whole or on our liquidity, capital resources or future 
results of operations. We will continue to evaluate proceedings and claims involving us on a regular basis and will establish and 
adjust any reserves as appropriate to reflect our assessment of the then current status of the matters.

Securities 

Market Information 

     Our common stock  trades on  the  NYSE  under the  symbol  “CXO.”  As of February  15, 2019,  there  were 1,461 holders  of 
record of our common stock. 

Dividend Policy 

On February 19, 2019, the Company’s board of directors approved a cash dividend of $0.125 per share for the first quarter 
of 2019. The total cash dividend, including the cash dividend on unvested restricted stock awards, of $25 million is expected to 
be paid on March 29, 2019. The Company intends to continue to pay a quarterly dividend of $0.125 in the near future; however, 
any payment of future dividends will be at the discretion of our board of directors and will depend on, among other things, our 
earnings, financial condition, capital requirements, level of indebtedness, statutory and contractual restrictions applying to the 
payment of dividends and other considerations that our board of directors deems relevant. Covenants contained in our Credit 
Facility  and  the  indentures  governing  our  senior  notes  could  limit  the  payment  of  dividends.  See  Note  10  of  the  Notes  to 
Consolidated  Financial  Statements  included  in  “Item  8.  Financial  Statements  and  Supplementary  Data”  for  additional

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations 

The following discussion is intended to assist you in understanding our business and results of operations together with our 
present financial condition. This section should be read in conjunction with our historical consolidated financial statements and 
notes, as well as the selected historical consolidated financial data included elsewhere in this report. 

Certain statements in our discussion below are forward-looking statements. These forward-looking statements involve risks 
and  uncertainties.  We  caution  that  a  number  of  factors  could  cause  actual  results  to  differ  materially  from  those  implied  or 
expressed by the forward-looking statements. Please see “Cautionary Statement Regarding Forward-Looking Statements” and 
“Item 1A. Risk Factors” for further details about these statements. 

Overview 

We are an independent oil and natural gas company engaged in the acquisition, development, exploration and production 
of oil and natural gas properties. We are one of the largest operators in the Permian Basin of Southeast New Mexico and West 
Texas. Concho’s legacy in the Permian Basin provides us a deep understanding of operating and geological trends, and we are 
actively developing our resource base utilizing large-scale development projects, which include long-lateral wells and multi-well 
pad locations, throughout our operating areas. Oil comprised 63 percent of our 1,187 MMBoe of estimated proved reserves at 
December 31, 2018 and 64 percent of our 96 MMBoe of production for 2018. We seek to operate the wells in which we own an 
interest, and we operated wells that accounted for 92 percent of our proved developed producing reserves and 77 percent of 
our 9,277 gross wells at December 31, 2018. By controlling operations, we are able to more effectively manage the cost and 
timing of exploration and development of our properties, including the drilling and stimulation methods used.

Financial and Operating Performance 

On July 19, 2018, we completed the RSP Acquisition, which, among other things, impacted the comparability of our results 

of operations. Our financial and operating performance for 2018 included the following highlights: 

•  Net income was $2,286 million ($13.25 per diluted share) as compared to net income of $956 million ($6.41 per diluted 

share) in 2017. The increase was primarily due to: 

• 

• 

• 

• 

$1,565 million increase in oil and natural gas revenues as a result of a 36 percent increase in production and 
a 18 percent increase in commodity price realizations per Boe (excluding the effects of derivative activities); 

$958 million change in (gain) loss on derivatives due to a $832 million gain on derivatives during 2018, as 
compared to a $126 million loss during 2017; 

$122 million net increase in gain on disposition of assets due to a gain of approximately $800 million during 
2018 primarily attributable to the February 2018 acquisition and divestiture primarily in the Midland Basin, the 
January  2018  divestiture  in  the  Delaware  Basin  and  the  contribution  of  certain  infrastructure  assets  to 
WaterBridge Operating LLC (“WaterBridge”) in December 2018, as compared to a net gain of approximately 
$678 million during 2017 primarily attributable to our disposition of ACC; and 

$86 million increase in other income, primarily due to a gain of approximately $103 million on the equity method 
investment distribution received from Oryx; 

partially offset by: 

• 

• 

• 

• 

• 

$678 million increase in our income tax provision primarily due to the income tax benefit recorded in 2017 as 
a result of the Tax Cuts and Jobs Act (the “TCJA”); 

$332  million  increase  in  depreciation,  depletion  and  amortization  expense,  primarily  due  to  an  increase  in 
production, partially offset by a lower depletion rate per Boe; 

$182  million  increase  in  production  expense,  primarily  due  to  (i)  increased  production  associated  with  our 
wells successfully drilled and completed in 2017 and 2018, (ii) our acquisitions and nonmonetary transactions 
during the fourth quarter of 2017 and during 2018, (iii) increased cost of services and (iv) increased workover 
costs; 

$106 million increase in production and ad valorem tax expense, primarily due to increased production taxes 
as a result of increased oil and natural gas sales; and 

$36 million increase in transaction costs, primarily due to consulting, investment banking, advisory, legal and 
other fees related to the RSP Acquisition. 

•  Average daily sales volumes increased by 36 percent from 192,658 Boe per day during 2017 to 262,937 Boe per day 

during 2018. 

•  Net  cash  provided  by  operating  activities  increased  by  approximately  $863  million  to  $2,558 million  for  2018,  as 
compared  to  $1,695 million  in  2017,  primarily  due  to  increased  oil  and  natural  gas  revenues,  partially  offset  by  (i) 
changes related to cash settlements on derivatives, (ii) increased production expense and (iii) increased production tax 
expense.

Commodity Prices 

Our results of operations are heavily influenced by commodity prices. See “Item 1A. Risk Factors” for a description of the 

factors that may impact future commodity prices, including the price of oil, natural gas and natural gas liquids. 

Although we cannot predict the occurrence of events that may affect future commodity prices or the degree to which these 
prices will be affected, the prices for any commodity that we produce will generally approximate current market prices in the 
geographic region of the production. From time to time, we expect that we may hedge a portion of our commodity price risk to 
mitigate the impact of price volatility on our business. See Notes 9 and 18 of the Notes to Consolidated Financial Statements 
included in “Item 8. Financial Statements and Supplementary Data” for additional information regarding our commodity derivative 
positions at December 31, 2018 and additional derivative contracts entered into subsequent to December 31, 2018, respectively. 

The following table sets forth the average NYMEX oil and natural gas prices for the years ended December 31, 2018, 2017 

and 2016, as well as the high and low NYMEX prices for the same periods:

Further, the NYMEX oil price and NYMEX natural gas price reached highs and lows of $55.59 and $45.41 per Bbl and $3.59 
and $2.55 per MMBtu, respectively, during the period from January 1, 2019 to February 15, 2019. At February 15, 2019, the 
NYMEX oil price and NYMEX natural gas price were $55.59 per Bbl and $2.63 per MMBtu, respectively. 

Historically, and during the year ended December 31, 2018, we derived a significant portion of our total natural gas revenues 
from the value of the natural gas liquids contained in our natural gas, with the remaining portion coming from the value of the 
dry natural gas residue. Because of our liquids-rich natural gas stream, and the related value of the natural gas liquids being 
included in our natural gas revenues, our realized natural gas price (excluding the effects of derivatives) reflected a price greater 
than the related NYMEX natural gas price for the year ended December 31, 2018. The average Mont Belvieu price for a blended 
barrel of natural gas liquids was $29.94 per Bbl, $25.06 per Bbl and $18.08 per Bbl during the years ended December 31, 2018, 
2017 and 2016, respectively. 

Potential cost inflation. Oilfield service and supply costs are also subject to supply and demand dynamics. As companies 
expand their drilling and development activities, the demand for third-party oilfield services and suppliers may also increase. As 
such, when commodity prices begin to trend upward, we expect demand for oilfield services and supplies to grow, and the costs 
of  drilling,  equipping  and  operating  our  wells  and  infrastructure  could  begin  to  rise.  Our  lease  operating  expenses  per  Boe 
increased during 2018 as compared to 2017, partially due to cost inflation resulting from these factors.

Recent Events 

2019 capital budget. In October 2018, our board of directors approved our 2019 capital budget of up to $3.8 billion. With 

current commodity prices, we expect to spend between $2.8 billion and $3.0 billion on drilling and completion activity. 

2019 dividends. On February 19, 2019, our board of directors declared a cash dividend of $0.125 per share for the first 
quarter of 2019. The total cash dividend, including cash dividend on unvested restricted stock awards, of $25 million is expected 
to be paid on March 29, 2019 to stockholders of record as of March 1, 2019. 

Marketing contract. Consistent with our strategy of diversifying our oil pricing, in January 2019, we entered into a firm 
sales  agreement  with  a  third-party  purchaser.  The  purchaser  provides  an  integrated  transportation  and  marketing  strategy, 
including ample dock capacity. The agreement has a term that ends five years after the startup of Cactus II Pipeline system and 
requires that we deliver 50,000 barrels of oil per day that will receive waterborne market pricing. 

RSP Acquisition. On July 19, 2018, we completed the RSP Acquisition. Under the terms of the Agreement and Plan of 
Merger (the “Acquisition Agreement”), each share of RSP common stock was converted into 0.320 of a share of our common 
stock. We issued approximately 51 million shares of common stock at a price of $148.27 per share, resulting in total consideration 
paid  to  the  former  RSP  shareholders  of  approximately  $7.5  billion.  Refer  to  Note  4  of  the  Notes  to  Consolidated  Financial 
Statements included in “Item 8. Financial Statements and Supplementary Data” for additional information regarding the RSP 
Acquisition. 

Long-term  debt.  On  July  2,  2018,  we  issued  $1,600  million  in  aggregate  principal  amount  of  unsecured  senior  notes, 
consisting of $1,000 million in aggregate principal amount of 4.3% unsecured senior notes due 2028 (the “4.3% Notes”) and 
$600 million in aggregate principal amount of 4.85% unsecured senior notes due 2048 (the “4.85% Notes” and, together with 
the 4.3% Notes, the “Notes”). The net proceeds of approximately $1,579 million were used to redeem and cancel all of RSP’s 
outstanding $700 million aggregate principal amount of 6.625% unsecured senior notes due 2022 (the “RSP 2022 Notes”) and 
$450 million aggregate principal amount of 5.25% unsecured senior notes due 2025 (the “RSP 2025 Notes” and, together with 
the  RSP 2022  Notes, the  “RSP  Notes”)  and  to  repay  a portion of  the outstanding  indebtedness under  RSP’s  existing  credit 
facility. We repaid the remaining balance under RSP’s credit facility with borrowings under our Credit Facility, resulting in a total 
payoff of $1,773 million, which included the accrued interest and premiums on the RSP notes and other fees and expenses 
related to RSP’s credit facility. 

Derivative Financial Instruments 

Derivative financial instrument exposure.  At December 31, 2018, the fair value of our financial derivatives was a net 
asset of $695 million. Under the terms of our financial derivative instruments, we do not have exposure to potential “margin calls” 
on our financial derivative instruments. The terms of our Credit Facility do not allow us to offset amounts we may owe a lender 
against amounts we may be owed related to our financial instruments with such party.  

New commodity derivative contracts. After December 31, 2018, we entered into derivative contracts to hedge additional 
amounts of estimated future production. Refer to Note 18 of the Notes to Consolidated Financial Statements included in “Item 
8. Financial Statements and Supplementary Data” for additional information regarding these commodity derivative contracts.

Results of Operations 

The following table sets forth summary production and operating data for the years ended December 31, 2018, 2017 and 
2016. The actual historical data in this table excludes results from the RSP Acquisition for periods prior to July 19, 2018 and the 
Reliance Acquisition for periods prior to October 2016. Because of normal production declines, increased or decreased drilling 
activities, fluctuations in commodity prices and the effects of acquisitions and divestitures, the historical information presented 
below should not be interpreted as being indicative of future results.

The presentation of average prices with derivatives is a result of including the net cash receipts from (payments on) 
commodity derivatives that are presented in our statements of cash flows. This presentation of average prices with 
derivatives is a means by which to reflect the actual cash performance of our commodity derivatives for the respective 
periods and presents oil and natural gas prices with derivatives in a manner consistent with the presentation generally 
used by the investment community.

Year Ended December 31, 2018 Compared to Year Ended December 31, 2017 

Oil  and  natural  gas  revenues.  Oil  and  natural  gas  operating  revenues  were  $4,151 million  for  the  year  ended 
December 31, 2018, an increase of $1,565 million (61 percent) from $2,586 million for 2017. This increase was primarily due to 
the increase in oil and natural gas production, partially due to the RSP Acquisition, as well as the increase in realized oil and 
natural gas prices (excluding the effects of derivative activities). Additionally, on January 1, 2018, we adopted ASC 606, which 
requires  certain  costs  related  to  gathering,  processing  and  transportation  to  be  separately  presented  on  the  consolidated 
statements of operations. Prior to the adoption of ASC 606, these costs were generally accounted for as a deduction to revenue 
and  included  within  total  operating  revenues  on  the  consolidated  statements  of  operations. We  elected  to  use  the  modified 
retrospective approach for adopting ASC 606, and as such, prior period amounts have not been restated. See Note 2 of the 
Notes  to  Consolidated  Financial  Statements  included  in  “Item 8.  Financial  Statements  and  Supplementary  Data”  for  more 
information regarding the adoption of ASC 606. Specific factors affecting oil and natural gas revenues include the following: 

• 

• 

• 

• 

total  oil  production  was  61,251  MBbl  for  the  year  ended  December 31,  2018,  an  increase  of  17,779  MBbl  (41 
percent) from 43,472 MBbl for 2017; 

average realized oil price (excluding the effects of derivative activities) was $56.22 per Bbl during the year ended 
December 31, 2018, an increase of 17 percent from $48.13 per Bbl during 2017. For the year ended December 
31, 2018, our crude oil price differential relative to NYMEX was $(8.59) per Bbl, or a realization of approximately 
87 percent, as compared to a crude oil price differential relative to NYMEX of $(2.84) per Bbl, or a realization of 
approximately 94 percent, for 2017. The basis differential (referred to as the “Mid-Cush differential”) between the 
location  of  Midland,  Texas  and  Cushing,  Oklahoma  (NYMEX  pricing  location)  for  our  oil  directly  impacts  our 
realized oil price. For the years ended December 31, 2018 and 2017, the average market Mid-Cush differential 
was a price reduction of $6.51 per Bbl and $0.30 per Bbl, respectively. Additionally, we incur fixed deductions from 
the posted Midland oil price based on the location of our oil within the Permian Basin. Our crude oil price differential 
relative to NYMEX excluding the Mid-Cush differential was $2.08 per Bbl for the year ended December 31, 2018, 
as compared to $2.54 per Bbl for the year ended December 31, 2017; 

total  natural  gas production  was 208,326  MMcf  for  the  year  ended  December 31,  2018,  an  increase  of  47,237 
MMcf (29 percent) from 161,089 MMcf for 2017; and 

average realized natural gas price (excluding the effects of derivative activities) was $3.40 per Mcf during the year 
ended  December  31,  2018,  an  increase  of  11  percent  from  $3.07  per  Mcf  during  2017.  For  the  years  ended 
December  31,  2018  and  2017,  we  realized  approximately  111 percent  and  102  percent,  respectively,  of  the 
average NYMEX natural gas prices for the respective periods. Historically, and during the year ended December 
31, 2018, we derived a significant portion of our total natural gas revenues from the value of the natural gas liquids 
contained  in  our  natural  gas,  with  the  remaining  portion  coming  from  the  value  of  the  dry  natural  gas  residue. 
Because of our liquids-rich natural gas stream and the related value of the natural gas liquids being included in our 
natural gas revenues, our realized natural gas price (excluding the effects of derivatives) reflected a price greater 
than the related NYMEX natural gas price for the year ended December 31, 2018. The increase in our realized 
natural gas price (excluding the effects of derivatives) as a percentage of NYMEX during the year ended December 
31, 2018 as compared to 2017 was primarily due to an increase in the average Mont Belvieu price for a blended 
barrel of natural gas liquids. The average Mont Belvieu price for a blended barrel of natural gas liquids was $29.94 
per Bbl and $25.06 per Bbl during the years ended December 31, 2018 and 2017, respectively. The increase in 
our realized natural gas price was also due to the adoption of ASC 606, as our natural gas realized price was $0.16 
per Mcf higher than what it would have been under the previous revenue standard. However, the increase was 
partially  offset  by  lower  regional  market  prices  for  natural  gas,  in  part  due  to  the  widening  of  the  regional 
differentials. During the latter part of 2018, amid concerns of rising natural gas production relative to natural gas 
takeaway in the Permian Basin, the natural gas price differential increased significantly. For example, during the 
fourth quarter of 2018, we realized approximately 76 percent of the average NYMEX natural gas prices.

Lease operating expenses were $553 million ($5.76 per Boe) for the year ended December 31, 2018, which was an increase 
of $166 million (43 percent) from $387 million ($5.50 per Boe) for the year ended December 31, 2017. The increase in lease 
operating expenses was primarily the result of increased production activities due to (i) additional wells successfully drilled and 
completed (ii) additional wells added from acquisitions, primarily the RSP Acquisition and (iii) overall increased cost of services. 
The increase in lease operating expenses per Boe was primarily due to the increase in lease operating expenses noted above, 
partially offset by an increase in production. 

Workover costs were $37 million ($0.38 per Boe) for the year ended December 31, 2018, which was an increase of $16 
million from $21 million ($0.30 per Boe) during 2017. The increase in workover costs during the year ended December 31, 2018 
as compared to 2017 was primarily due to increased workover activity and higher cost of services. The increase in workover 
costs per Boe was primarily due to the increase in workover costs noted above, partially offset by an increase in production. 

Production and ad valorem taxes.  The following table provides the components of our production and ad valorem tax

Production taxes per unit of production were $2.84 per Boe during the year ended December 31, 2018, an increase of 10 
percent  from  $2.58  per  Boe  during  2017.  Over  the  same  period,  our  revenue  per  Boe  (excluding  the  effects  of  derivatives) 
increased 18 percent.  The increase  in  production taxes  per  unit  of production  was  directly  related  to  the  increase  in  oil  and 
natural gas sales, partially offset by a higher percentage of our total production originating in Texas, which has a lower tax rate 
than New Mexico. Production taxes fluctuate with the market value of our production sold, while ad valorem taxes are generally 
based on the valuation of our oil and natural gas properties at the beginning of the year, which vary across the different areas 
in which we operate. Ad valorem taxes increased by $15 million primarily due to additional wells drilled and completed, new 
wells acquired in the RSP Acquisition and an increase in property values. The increase in ad valorem taxes per Boe was primarily 
due to an increase in property values.

Gathering, processing and transportation costs were $55 million ($0.58 per Boe) for the year ended December 31, 2018. 
On January 1, 2018, we adopted ASC 606, which requires certain amounts related to gathering, processing and transportation 
costs to be separately presented on the consolidated statements of operations. Prior to the adoption of ASC 606, the majority 
of these costs were accounted for as a deduction to revenue and included within total operating revenues on the consolidated 
statements of operations. We have elected to use the modified retrospective approach for adopting ASC 606, and as such, prior 
period  amounts  have  not  been  restated.  In  addition,  our  gathering,  processing  and  transportation  costs  are  impacted  by 
production volumes and fixed costs associated with certain contracts. 

Exploration  and  abandonments  expense.  The  following  table  provides  the  components  of  our  exploration  and

Our geological and geophysical expense for the periods presented above primarily consists of the costs of acquiring and 

processing geophysical data and core analysis. 

For the years ended December 31, 2018 and 2017, we recorded approximately $35 million and $27 million, respectively, 
of  leasehold abandonments. Our  leasehold  abandonments  for the  year ended  December  31,  2018 and  2017  were primarily 
related to certain expiring acreage and acreage where we had no future plans to drill.  

Our other expense for the periods presented above primarily consists of surface and title costs on locations we no longer 

intend to drill, certain plugging costs and delay rentals.

2018, an increase of $331 million (30 percent) from $1,122 million ($15.95 per Boe) for 2017. The increase in depletion expense 
was primarily due to an increase in production, partially offset by a lower depletion rate per Boe. The decrease in depletion 
expense per Boe was primarily due to the increase in proved reserves due to our successful exploratory drilling program, cost 
reductions and higher oil prices, partially offset by the RSP Acquisition.

2018, an increase of $67 million (27 percent) from $244 million ($3.46 per Boe) for 2017. The increase in cash general and 
administrative and non-cash stock-based compensation expenses was primarily driven by the increase in employee headcount. 
The decrease in total general and administrative expenses per Boe was primarily the result of increased production, partially 
offset by the increase in total general and administrative expenses noted above. 

We receive fees for the operation of jointly-owned oil and natural gas properties during the drilling and production phases 
and  record  such  reimbursements  as  reductions  of  general  and  administrative  expenses  in  the  consolidated  statements  of 
operations. We earned reimbursements of approximately $19 million and $16 million during the years ended December 31, 2018 
and 2017, respectively.

Our  earnings  are  affected  by  the  changes  in  value  of  our  derivatives  portfolio  between  periods  and  the  related  cash 
settlements of those derivatives, which could be significant. To the extent the future commodity price outlook declines between 
measurement periods, we will have mark-to-market gains; while to the extent future commodity price outlook increases between 
measurement  periods,  we  will  have  mark-to-market  losses.  See  Note  8  of  the  Notes  to  Consolidated  Financial  Statements 
included in “Item 8. Financial Statements and Supplementary Data” for additional information regarding significant judgments 
made in classifying financial instruments in the fair value hierarchy. 

Gain on disposition of assets, net. During the years ended December 31, 2018 and 2017, we recognized a non-cash net 
gain on disposition of assets of approximately $800 million and $678 million respectively. The net gain during 2018 was primarily 
due to (i) a gain of approximately $575 million related to our February 2018 acquisition and divestiture primarily in the Midland 
Basin,  (ii)  a  gain of  approximately  $134  million  related  to  our  Delaware  Basin divestiture  in  January  2018 and  (iii)  a  gain  of 
approximately $79 million related to the contribution of certain infrastructure assets in the southern portion of our Delaware Basin 
to WaterBridge in December 2018. See Note 2 of the Notes to Consolidated Financial Statements included in “Item 8. Financials 
Statements and Supplementary Data” for additional information regarding our transaction with WaterBridge. In addition, during 
2018, we completed multiple nonmonetary transactions that included the exchange of both proved and unproved oil and natural 
gas properties. Certain of these transactions were accounted for at fair value, and as a result, we recorded pre-tax gains of 
approximately $15 million. 

In February 2017, we closed on the divestiture of our ownership interest in ACC. After adjustments for debt and working 
capital, we received cash proceeds from the sale of approximately $801 million. After direct transaction costs, we recorded a 
pre-tax  gain  on  disposition  of  assets  of  approximately  $655  million.  Our  net  investment  in  ACC  at  the  time  of  closing  was 
approximately $129 million.  

See  Note  5  of  the  Notes  to  Consolidated  Financial  Statements  included  in  “Item  8.  Financials  Statements  and 

Supplementary Data” for additional information regarding our significant divestitures and nonmonetary transactions.

The  increase  in  interest  expense  was  due to  the  increase  in  the  weighted  average  debt balance, partially  offset by  the 
decrease in the weighted average interest rate and an increase in capitalized interest. The increase in the weighted average 
debt balance was due primarily to the Notes issued in connection with the RSP Acquisition.  

Loss  on  extinguishment  of  debt.    We  recorded  a  loss  on  extinguishment  of  debt  of  $66  million  for  the  year  ended 
December 31, 2017. This amount includes: (i) approximately $36 million associated with the premium paid for the cash tender 
offer  (“Tender  Offer”)  and  redemption  of  the  5.5%  unsecured  senior  notes  due  2022  (the  “5.5%  Notes”),  approximately  $25 
million associated with the make-whole premium paid for the early extinguishment of the 5.5% Notes, approximately $21 million 
of unamortized deferred loan costs and approximately $2 million of additional interest on the 5.5% Notes to October 13, 2017, 
which was paid in September 2017, reduced by approximately $19 million of unamortized premium; and (ii) approximately $1 
million representing the proportional amount of unamortized deferred loan costs associated with banks that are no longer in our 
Credit Facility syndicate as a result of the April 2017 amendment to our Credit Facility. 

Other income, net. During the year ended December 31, 2018, we recorded other income of approximately $108 million 
primarily  related  to  a  cash  distribution  received  from  Oryx.  See  Note  2  of  the  Notes  to  Consolidated  Financial  Statements 
included in “Item 8. Financial Statements and Supplementary Data” for additional information regarding this distribution.  

Income tax provisions.  For the year ended December 31, 2018, we recorded income tax expense of approximately $603 
million. For the year ended December 31, 2017, we recorded an income tax benefit of approximately $75 million, which includes 
the $398 million provisional income tax benefit that was recognized as a result of the favorable income tax rate change enacted 
through the TCJA in December 2017. At December 31, 2018, the Company completed its accounting for all of the enactment-
date tax effects of the TCJA and recognized an adjustment to this provisional amount of approximately $7 million primarily related 
to the deductibility of certain performance-based compensation expenses. 

The  effective  income  tax  rates  for  the  years  ended  December 31,  2018  and  2017  were  21 percent  and  (9)  percent, 
respectively. Our 2018 effective tax rate more closely aligns with the 21 percent federal statutory rate enacted by the TCJA while 
our 2017 effective tax rate reflects the $398 million income tax benefit recognized due to the decrease in the federal income tax 
rate from 35 percent to 21 percent enacted by the TCJA.  

We  evaluate  changes  to  our  industry,  production,  market  conditions  and  changes  in  our  forecasted  drilling  plan  by  tax 
jurisdiction. Our material state tax jurisdictions include Texas and New Mexico. In July 2018, as part of the RSP Acquisition, we 
acquired property primarily located in Texas. As such, we identified a slight shift in our projected future apportionment between 
New  Mexico  and  Texas  for  the  year  ended  December  31,  2018.  As  a  result,  we  recognized  a  state  deferred  tax  benefit  of 
approximately $8 million for the year ended December 31, 2018. We did not identify a shift in our projected future apportionment 
for the year ended December 31, 2017.

Year Ended December 31, 2017 Compared to Year Ended December 31, 2016 

Oil  and  natural  gas  revenues.  Oil  and  natural  gas  operating  revenues  were  $2,586 million  for  the  year  ended 
December 31, 2017, an increase of $951 million (58 percent) from $1,635 million for 2016. This increase was primarily due to 
the increase in oil and natural gas production as well as the increase in realized oil and natural gas prices (excluding the effects 
of derivative activities). Specific factors affecting oil and natural gas revenues include the following: 

• 

• 

• 

• 

total  oil  production  was  43,472  MBbl  for  the  year  ended  December 31,  2017,  an  increase  of  9,632  MBbl  (28 
percent) from 33,840 MBbl for 2016; 

average realized oil price (excluding the effects of derivative activities) was $48.13 per Bbl during the year ended 
December 31, 2017, an increase of 21 percent from $39.90 per Bbl during 2016. For the year ended December 
31, 2017, our crude oil price differential relative to NYMEX was $(2.84) per Bbl, or a realization of approximately 
94 percent, as compared to a crude oil price differential relative to NYMEX of $(3.52) per Bbl, or a realization of 
approximately 92 percent, for 2016. The basis differential between the location of Midland, Texas and Cushing, 
Oklahoma (NYMEX pricing location) for our oil directly impacts our realized oil price. For the year ended December 
31,  2017 and 2016,  the  average  market  basis  differential  between WTI-Midland  and WTI-Cushing  was  a price 
reduction of $0.30 per Bbl and $0.15 per Bbl, respectively. Additionally, we incur fixed deductions from the posted 
Midland oil price based on the location of our oil within the Permian Basin. These fixed deductions were less per 
Boe during the year ended December 31, 2017 as compared to 2016 primarily due to more production transported 
through pipelines and successful renegotiation of fixed deductions for trucked volumes; 

total  natural  gas production  was 161,089  MMcf  for  the  year  ended  December 31,  2017,  an  increase  of  33,608 
MMcf (26 percent) from 127,481 MMcf for 2016; and 

average realized natural gas price (excluding the effects of derivative activities) was $3.07 per Mcf during the year 
ended  December  31,  2017,  an  increase  of  38  percent  from  $2.23  per  Mcf  during  2016.  For  the  years  ended 
December 31, 2017 and 2016, we realized approximately 102 percent and 87 percent, respectively, of the average 
NYMEX natural gas prices for the respective periods. The increase in our realized natural gas price (excluding the 
effects of derivatives) as a percentage of NYMEX during the year ended December 31, 2017 as compared to 2016 
was primarily due to an increase in the average Mont Belvieu price for a blended barrel of natural gas liquids. 
Historically, and during the year ended December 31, 2017, we derived a significant portion of our total natural gas 
revenues from the value of the natural gas liquids contained in our natural gas, with the remaining portion coming 
from the value of the dry natural gas residue. The average Mont Belvieu price for a blended barrel of natural gas 
liquids was $25.06 per Bbl and $18.08 per Bbl during the years ended December 31, 2017 and 2016, respectively.

Lease operating expenses were $387 million ($5.50 per Boe) for the year ended December 31, 2017, which was an increase 
of $86 million (29 percent) from $301 million ($5.46 per Boe) for the year ended December 31, 2016. The increase in lease 
operating expenses was primarily due to (i) increased production associated with our wells successfully drilled and completed 
in 2016 and 2017, (ii) our acquisitions during the fourth quarter of 2016 and during 2017, particularly the Reliance Acquisition 
and our Midland Basin acquisition, whose associated properties incur higher lease operating expense per Boe than our legacy 
assets and (iii) increased cost of services.

Production taxes per unit of production were $2.58 per Boe during the year ended December 31, 2017, an increase of 21 
percent  from  $2.13  per  Boe  during  2016.  Over  the  same  period,  our  revenue  per  Boe  (excluding  the  effects  of  derivatives) 
increased 24 percent.  The increase  in  production taxes  per  unit  of production  was  directly  related  to  the  increase  in  oil  and 
natural gas sales, partially offset by a $5 million tax credit received during 2017 related to certain wells in Texas qualifying for 
reduced severance tax rates, as compared to $4 million in tax credit received during 2016. Production taxes fluctuate with the 
market value of our production sold, while ad valorem taxes are generally based on the valuation of our oil and natural gas 
properties at the beginning of the year, which vary across the different areas in which we operate.

Our geological and geophysical expense for the periods presented above primarily consists of the costs of acquiring and 

processing geophysical data and core analysis. 

Our exploratory dry hole costs during the year ended December 31, 2016 were primarily related to an uneconomic well in 
the  Delaware  Basin  that  was  attempting  to  establish  commercial  production  through  testing  of  multiple  zones.  We  did  not 
recognize any exploratory dry hole costs during the year ended December 31, 2017. 

For the years ended December 31, 2017 and 2016, we recorded approximately $27 million and $50 million, respectively, 
of leasehold abandonments. For the year ended December 31, 2017, our abandonments were primarily in the Delaware Basin 
related to acreage expiring and acreage where we have no future plans to drill. For the year ended December 31, 2016, our 
abandonments were primarily in the Delaware Basin related to (i) drilling locations that, based on multiple factors, were no longer 
likely to be drilled, (ii) acreage with no future development plans and (iii) expiring acreage. 

Our other expense for the periods presented above primarily consists of surface and title costs on locations we no longer 

intend to drill, certain plugging costs and delay rentals.

Depletion of proved oil and natural gas properties was $1,122 million ($15.95 per Boe) for the year ended December 31, 
2017, a decrease of $23 million (2 percent) from $1,145 million ($20.79 per Boe) for 2016. The decrease in depletion expense 
was  primarily  due  to a  lower  depletion  rate  per  Boe  partially  offset  by  an increase  in  production.  The  decrease in  depletion 
expense per Boe was primarily due to (i) lower drilling and completion costs per Boe of proved developed reserves added, (ii) 
an overall increase in proved reserves primarily caused by our successful exploratory drilling program, the Reliance Acquisition 
as  well  as  other  acquisitions,  and  higher  commodity  prices,  partially  offset  by  decreased  proved  reserves  caused  by 
reclassification of proved undeveloped reserves to unproved reserves because they were no longer expected to be developed 
within  five  years  of  the  date  of  their  initial  recognition  and  (iii)  a  non-cash  impairment  charge  of  approximately  $1.5  billion 
recorded in the first quarter of 2016.

Impairments  of  long-lived  assets.  We  did  not  recognize an  impairment  charge during the  year  ended  December  31, 
2017. During the three months ended March 31, 2016, we recognized a non-cash impairment charge of approximately $1.5 
billion. The impairment during the three months ended March 31, 2016 was primarily due to a decline in NYMEX strip prices, 
which resulted in the carrying amount of our Yeso field in the Delaware Basin to exceed the expected undiscounted future net 
cash flows of the field. Our estimates of commodity prices for purposes of determining the estimated fair value at March 31, 
2016 ranged from a 2016 price of $41.26 per barrel of oil and $2.26 per Mcf of natural gas to a 2023 price of $66.33 per barrel 
of oil and $3.56 per Mcf of natural gas. Commodity prices for this purpose were held flat after 2023. See Note 2 and Note 8 of 
the  Notes  to  Consolidated  Financial  Statements  included  in  “Item  8.  Financial  Statements  and  Supplementary  Data”  for 
additional information on impairments of long-lived assets.

General and administrative expenses were approximately $244 million ($3.46 per Boe) for the year ended December 31, 
2017,  an  increase  of  $18  million  (8  percent)  from  $226  million  ($4.09  per  Boe)  for 2016.  The  increase  in cash  general  and 
administrative  expenses  was  primarily  a  result  of  increased  compensation  expense.  The  decrease  in  total  general  and 
administrative expenses per Boe was primarily due to increased production, partially offset by the increase in cash general and 
administrative costs noted above. 

We receive fees for the operation of jointly-owned oil and natural gas properties during the drilling and production phases 
and  record  such  reimbursements  as  reductions  of  general  and  administrative  expenses  in  the  consolidated  statements  of 
operations. We earned reimbursements of approximately $16 million and $17 million during the years ended December 31, 2017 
and 2016, respectively.

Our  earnings  are  affected  by  the  changes  in  value  of  our  derivatives  portfolio  between  periods  and  the  related  cash 
settlements of those derivatives, which could be significant. To the extent the future commodity price outlook declines between 
measurement periods, we will have mark-to-market gains; while to the extent future commodity price outlook increases between 
measurement  periods,  we  will  have  mark-to-market  losses.  See  Note  8  of  the  Notes  to  Consolidated  Financial  Statements 
included in “Item 8. Financial Statements and Supplementary Data” for additional information regarding significant judgments 
made in classifying financial instruments in the fair value hierarchy. 

Gain  on  disposition  of  assets,  net.  During  the  years  ended  December  31,  2017  and  2016,  we  recognized  a  gain  on 
disposition of assets of approximately $678 million and $118 million, respectively. In February 2017, we closed on the divestiture 
of our ownership interest in ACC. After adjustments for debt and working capital, we received cash proceeds from the sale of 
approximately $801 million. After direct transaction costs, we recorded a pre-tax gain on disposition of assets of approximately 
$655 million. Our net investment in ACC at the time of closing was approximately $129 million. In February 2016, we sold certain 
assets in the Delaware Basin for proceeds of approximately $292 million and recognized a pre-tax gain of approximately $110 
million.

The decrease in interest expense was due to the decrease in the weighted average debt balance and the weighted average 
interest  rate.  Our  weighted  average  debt  balance  decreased  for  the  year  ended  December  31,  2017  as  compared  to  2016 
primarily due to (i) the satisfaction and discharge of the 6.5% unsecured senior notes due 2022 (the “6.5% Notes”) in December 
2016,  (ii)  the  redemption  of  the  7.0%  unsecured  senior  notes  due  2021  (the  “7.0%  Notes”)  in  September  2016  and  (iii)  the 
repurchases and redemption of the 5.5% Notes in September 2017, partially offset by (i) the issuance of the 4.375% unsecured 
senior notes due 2025 (the “4.375% Notes”) in December 2016, (ii) the issuance of the 3.75% unsecured senior notes due 2027 
(the “3.75% Notes”) and the 4.875% unsecured senior notes due 2047 (the “4.875% Notes” and, together with the 3.75% Notes, 
the “2017 Notes”) and (iii) an increase in borrowings under our Credit Facility. The decrease in interest expense was due to the 
overall decrease in the weighted average debt balance and an increase in capitalized interest. 

Loss  on  extinguishment  of  debt.    We  recorded  a  loss  on  extinguishment  of  debt  of  $66  million  for  the  year  ended 
December 31, 2017. This amount includes: (i) approximately $36 million associated with the premium paid for the cash tender 
offer, approximately $25 million associated with the make-whole premium paid for the early extinguishment of the 5.5% Notes, 
approximately $21 million of unamortized deferred loan costs and approximately $2 million of additional interest on the 5.5% 
Notes to October 13, 2017, which was paid in September 2017, reduced by approximately $19 million of unamortized premium; 
and (ii) approximately $1 million representing the proportional amount of unamortized deferred loan costs associated with banks 
that are no longer in our Credit Facility syndicate as a result of the April 2017 amendment to our Credit Facility. 

We recorded a loss on extinguishment of debt of $56 million for the year ended December 31, 2016. This amount includes: 
(i) approximately $20 million associated with the make-whole premium paid for the early extinguishment of the 6.5% Notes in 
December 2016, approximately $7 million of related unamortized deferred loan costs and approximately $1 million of additional 
interest on the 6.5% Notes through January 16, 2017, which was paid in December 2016; and (ii) $21 million associated with 
the make-whole premium paid for the early redemption of the 7.0% Notes in September 2016 and approximately $7 million of 
related unamortized deferred loan costs. 

Income tax provisions.  For the year ended December 31, 2017, we recorded an income tax benefit of $75 million, which 
included discrete provisional income tax benefits of approximately $398 million related to the enactment of the TCJA and $6 
million related to stock-based awards recorded in the income tax provision pursuant to Accounting Standards Update No. 2016-
09, “Compensation–Stock Compensation (Topic 718): Improvements to Employee Share-based Payment Accounting” adopted 
on January 1, 2017. For the year ended December 31, 2016, we recorded an income tax benefit of $876 million primarily due to 
having a loss before income taxes.  

The change in our income tax provision in 2017 as compared to 2016 was primarily due to the favorable impacts of the tax 
law changes enacted through the TCJA in December 2017 as the income tax benefit related to the federal statutory rate change 
more than offset our income tax expense of $308 million on income before income taxes during 2017. The effective income tax 
rates  for  the  years  ended  December 31,  2017  and  2016  were  (9) percent  and  38  percent,  respectively.  The  2017  rate  was 
negative due to recognizing an overall income tax benefit while having pre-tax income. 

We  evaluate  changes  to  our  industry,  production,  market  conditions  and  changes  in  our  forecasted  drilling  plan  by  tax 
jurisdiction. Our material state tax jurisdictions include Texas and New Mexico. In February 2017, we sold our ownership interest 
in ACC, which consisted of property in both Texas and New Mexico, and in April 2017, we completed an acquisition of assets in 
the Delaware Basin. We have considered these and other factors and did not identify a shift in our projected future apportionment 
between New Mexico and Texas for the year ended December 31, 2017. In October 2016, we purchased Texas-based assets

in the Reliance Acquisition for approximately $1.7 billion, which caused a shift in our projected future apportionment from New 
Mexico to Texas, which has a lower statutory state tax rate than New Mexico. As such, we recognized an overall state deferred 
tax benefit of approximately $21 million for the year ended December 31, 2016.

Capital Commitments, Capital Resources and Liquidity 

Capital commitments. Our primary needs for cash are development, exploration and acquisition of oil and natural gas 
assets, payment of contractual obligations and working capital obligations. Funding for these cash needs may be provided by 
any combination of internally-generated cash flow, financing under our credit facility, proceeds from the disposition of assets or 
alternative financing sources, as discussed in “— Capital resources” below. 

Oil and natural gas properties. Our costs incurred on oil and natural gas properties, excluding acquisitions, during the 
years ended December 31, 2018, 2017 and 2016 totaled $2.6 billion, $1.7 billion and $1.2 billion, respectively. The increase was 
primarily due to our increased drilling and completion activity level during 2018 as compared to 2017 and 2016. Our intent is to 
manage our capital spending to be within our operating cash flow, excluding unbudgeted acquisitions. The primary reason for 
the differences in costs incurred and cash flow expenditures was the timing of payments. Total 2018 expenditures were primarily 
funded in part from cash flows from operations and proceeds from our January 2018 Delaware Basin divestitures. 

2019 capital budget. In October 2018, our board of directors approved our 2019 capital budget of up to $3.8 billion. With 

current commodity prices, we expected to spend between $2.8 billion and $3.0 billion on drilling and completion activity.  

2019 dividends. On February 19, 2019, our board of directors declared a cash dividend of $0.125 per share for the first 
quarter of 2019. The total cash dividend, including cash dividend on unvested restricted stock awards, of $25 million is expected 
to be paid on March 29, 2019 to stockholders of record as of March 1, 2019. We intend to continue to pay a quarterly dividend 
of  $0.125  in  the  future, however,  any  payment of  future  dividends  will  be  at  the  discretion  of  our  board  of  directors and  will 
depend  on,  among  other  things,  our  earnings,  financial  condition,  capital  requirements,  level  of  indebtedness,  statutory  and 
contractual restrictions applying to the payment of dividends and other considerations that our board of directors deems relevant. 

Other than the customary purchase of leasehold acreage, our capital budgets are exclusive of acquisitions. We do not have 
a specific acquisition budget because the timing and size of acquisitions are difficult to forecast. We evaluate opportunities to 
purchase or sell oil and natural gas properties in the marketplace and could participate as a buyer or seller of properties at 
various  times. We  seek  to  acquire  oil  and  natural  gas  properties  that  provide  opportunities  for  the  addition  of  reserves  and 
production through a combination of development, high-potential exploration and control of operations that will allow us to apply 
our operating expertise, such as the RSP Acquisition. 

Acquisitions. The following table reflects our expenditures for acquisitions of proved and unproved properties for the years 

ended December 31, 2018, 2017 and 2016:

unbudgeted acquisitions during 2018 were primarily comprised of approximately $7.6 billion of property acquisition costs 
related to the RSP Acquisition. Our unbudgeted acquisitions during 2017 were primarily comprised of approximately $1.1 
billion  of  property  acquisition  costs  related  to  our  Midland  Basin  and  Delaware  Basin  acquisitions.  Our  unbudgeted 
acquisitions during 2016 were primarily comprised of approximately $2.1 billion of property acquisition costs related to the 
Reliance Acquisition and Delaware Basin acquisition.

Off-balance sheet arrangements. Currently, we do not have any material off-balance sheet arrangements. 

Capital  resources.  Our  primary  sources  of  liquidity  have  been  cash  flows  generated  from  (i)  operating  activities,  (ii) 
borrowings under our Credit Facility, (iii) proceeds from bond and equity offerings and (iv) asset dispositions. In October 2018, 
our board of directors approved our 2019 capital budget of up to $3.8 billion. With current commodity prices, we expect to spend 
between $2.8 billion and $3.0 billion on drilling and completion activity.

Cash flow from operating activities. The increase in operating cash flows during the year ended December 31, 2018 as 
compared to 2017 was primarily due to an increase in oil and natural gas revenues of approximately $1.6 billion, partially offset 
by (i) a decrease in operating cash flow of approximately $297 million due to approximately $218 million for settlements paid on 
derivatives during the year ended December 31, 2018, as compared to approximately $79 million in settlements received from 
derivatives  during  2017,  (ii)  approximately  $182  million  increase  in  production  expense  and  (iii)  approximately  $106  million 
increase in production tax expense. 

The increase in operating cash flows during the year ended December 31, 2017 as compared to 2016 was primarily due to 
an  increase  in  oil  and  natural  gas  revenues  of  approximately  $951  million  and  a  decrease  in  cash  interest  expense  of 
approximately $55 million, partially offset by (i) approximately $546 million decrease in settlements received from derivatives, 
(ii)  approximately  $88  million  increase  in  production  expense  and  (iii)  approximately  $68  million  increase  in  production  tax 
expense. 

Our net cash provided by operating activities included a benefit of approximately $4 million, a reduction of approximately 
$23 million and a reduction of approximately $51 million for the years ended December 31, 2018, 2017 and 2016, respectively, 
associated with changes in working capital items. Changes in working capital items adjust for the timing of receipts and payments 
of actual cash. 

Cash flow from investing activities. Our investing activities consist primarily of drilling and completion activity, acquisitions 
and divestitures. The primary reason for the differences in costs incurred on oil and natural gas properties, including acquisitions, 
and cash flow expenditures is the timing of payments and the issuances of shares of common stock to fund certain acquisitions. 

For  the  year  ended  December  31,  2018, our net cash used  in investing  activities  was  approximately  $2.2 billion,  which 
consisted  primarily  of  our  investment  of  approximately  $2.5  billion  for  additions  to  oil  and  natural  gas  properties  and 
approximately  $136  million  of  oil  and  natural  gas  property  acquisitions,  partially  offset  by  (i)  approximately  $361  million  of 
proceeds received from the disposition of certain assets and (ii) a $148 million distribution received from Oryx, one of our equity 
method  investments.  The  total  distribution  from  Oryx  was  approximately  $157  million,  of  which  approximately  $9  million 
represented cumulative Oryx earnings and was classified as cash flow from operating activities, while the remaining amount of 
approximately $148 million was classified as cash flow from investing activities. The 2018 expenditures were primarily funded 
with cash flows from operations. 

For  the  year  ended  December  31,  2017, our net cash used  in investing  activities  was  approximately  $1.7 billion,  which 
consisted  primarily  of  our  investment  of  approximately  $1.6  billion  for  additions  to  oil  and  natural  gas  properties  and 
approximately $908 million of oil and natural gas property acquisitions. This was partially offset by approximately $803 million of 
proceeds received from the disposition of certain assets. The 2017 expenditures were primarily funded in part from (i) cash flows 
from  operations,  (ii) proceeds  from  our February  2017  divestiture  of  ACC  and  (iii) our  issuance  of  approximately  2.2 million 
shares of common stock related to our Delaware Basin acquisition. 

For  the  year  ended  December  31,  2016, our net cash used  in investing  activities  was  approximately  $2.2 billion,  which 
consisted  primarily  of  our  investment  of  approximately  $1.0  billion  for  additions  to  oil  and  natural  gas  properties  and 
approximately $1.4 billion of oil and natural gas property acquisitions. This was partially offset by approximately $332 million of 
proceeds received from the disposition of certain assets. The 2016 expenditures were funded in part from (i) proceeds from our 
February 2016 divestiture,  (ii)  our  issuance of  approximately  2.2 million  shares  of common stock  related  to  our  March  2016

acquisition,  (iii)  proceeds  from  our  August  2016  equity  offering  and  (iv)  our  issuance  of  approximately  3.9  million  shares  of 
common stock related to the Reliance Acquisition. 

Cash flow from financing activities. For the year ended December 31, 2018, our net cash used in financing activities was 
approximately $342 million. In July 2018, we issued $1,600 million in aggregate principal amount of the Notes, for which we 
received net proceeds of approximately $1,579 million. We used the net proceeds to redeem and cancel the RSP Notes. We 
made  aggregate  payments  of  approximately  $1.2  billion  to  redeem  and  cancel  the  RSP  Notes,  including  make-whole  call 
premiums of approximately $35 million and $33 million for the RSP 2022 Notes and the RSP 2025 Notes, respectively. We also 
paid accrued interest of approximately $14 million on the RSP Notes. The remaining proceeds, along with borrowings under our 
Credit Facility, were used to repay the $540 million of outstanding principal under RSP’s revolving credit facility, including $1 
million in accrued interest. We also made net payments of $80 million on our Credit Facility during 2018.  

For  the  year  ended  December  31,  2017,  our  net  cash  used  in  financing  activities  was  approximately  $29  million.  In 
September 2017, we issued $1,800 million in aggregate principal amount of the 2017 Notes, for which we received net proceeds 
of approximately $1,777 million. We used the net proceeds from the offering, together with cash on hand and borrowings under 
our Credit Facility, to fund the (i) Tender Offer of $1,232 million principal amount of the 5.5% Notes at a price equal to 102.934 
percent  of  par  and  (ii)  redemption  of  our  remaining  obligations  of  the  $918  million  outstanding  principal  amount  under  the 
indentures of the 5.5% Notes at a price equal to 102.75 percent of par. The early extinguishment price included approximately 
$36 million associated with the premium paid for the Tender Offer, approximately $25 million for the make-whole premium paid 
for the early extinguishment of the 5.5% Notes and approximately $2 million for prepaid interest as part of the satisfaction and 
discharge. We also had net borrowings of $322 million under our Credit Facility during 2017. 

For  the  year  ended  December  31,  2016,  our  net  cash  provided  by  financing  activities  was  approximately  $665  million 

primarily due to the following activities: 

• 

• 

• 

In August 2016, we issued approximately 10.4 million shares of our common stock in a public offering at $130.90 
per share and received net proceeds of approximately $1.3 billion. We used a portion of the net proceeds to finance 
part of the cash portion of the purchase price for the Reliance Acquisition and to fund part of the early redemption 
of the 7.0% Notes and the remainder for general corporate purposes. 

In September 2016, we redeemed the $600 million outstanding principal amount of the 7.0% Notes at a price equal 
to 103.5 percent of par. The redemption price included the make-whole premium for the early redemption of $21 
million. 

In December 2016, we issued $600 million in aggregate principal amount of 4.375% senior notes due 2025 at par, 
for which we received net proceeds of approximately $593 million. We used the net proceeds from the offering to 
fund the satisfaction and discharge of our obligations under the indenture of the $600 million outstanding principal 
amount of the 6.5% Notes at a price equal to 103.25 percent of par. The early extinguishment price included the 
make-whole premium of $20 million. 

In April 2017, we amended our Credit Facility to decrease our unused lender commitments. In September 2017, we elected 
to enter into an Investment Grade Period under our Credit Facility, which had the effect of releasing all collateral formerly securing 
our Credit Facility. If the Investment Grade Period under our Credit Facility terminates (whether automatically or by our election), 
our Credit Facility will once again be secured by a first lien on substantially all of our oil and natural gas properties and by a 
pledge of the equity interests in our subsidiaries. At December 31, 2018, we had unused commitments under our Credit Facility 
of $1.8 billion. 

Advances on our Credit Facility bear interest, at our option, based on: (i) an alternative base rate, which is equal to the 
highest of (a) the prime rate of JPMorgan Chase Bank (5.5 percent at December 31, 2018), (b) the federal funds effective rate 
plus 0.5 percent and (c) LIBOR plus 1.0 percent; or (ii) LIBOR. The Credit Facility’s interest rates and commitment fees on the 
unused portion of the available commitment vary depending on our credit ratings from Moody’s and S&P. At our current credit 
ratings, LIBOR Rate Loans and Alternate Base Rate Loans bear interest margins of 150 basis points and 50 basis points per 
annum, respectively, and commitment fees on the unused portion of the available commitment are 25 basis points per annum. 

In conducting our business, we may utilize various financing sources, including the issuance of (i) fixed and floating rate 
debt,  (ii)  convertible  securities,  (iii)  preferred  stock,  (iv)  common  stock  and  (v)  other  securities.  Historically,  we  have 
demonstrated our use of the capital markets by issuing common stock and senior unsecured debt. There are no assurances 
that we can access the capital markets to obtain additional funding, if needed, and at cost and terms that are favorable to us. 
We  may  also  sell  assets  and  issue  securities  in  exchange  for  oil  and  natural  gas  assets  or  interests  in  energy  companies. 
Additional securities may be of a class senior to common stock with respect to such matters as dividends and liquidation rights 
and may also have other rights and preferences as determined from time to time. Utilization of some of these financing sources 
may require approval from the lenders under our Credit Facility. 

Liquidity. Our principal source of liquidity is the available borrowing capacity under our Credit Facility. At December 31, 

2018, our commitments from our bank group were $2.0 billion of which $1.8 billion was unused commitments.  

64 

    
 
 
 
 
 
 
  
  
 
 
Debt ratings. We receive debt credit ratings from S&P, Moody’s and Fitch and are designated as investment grade with all 
three  agencies.  In  determining  our  ratings,  the  agencies  perform  regular  reviews  and  consider  a  number  of  qualitative  and 
quantitative factors including, but not limited to, the industry in which we operate, production growth opportunities, liquidity, debt 
levels and asset and reserve mix. 

A downgrade in our credit ratings could (i) negatively impact our costs of capital and our ability to effectively execute aspects 
of our strategy, (ii) affect our ability to raise debt in the public debt markets, and the cost of any new debt could be much higher 
than our outstanding debt and (iii) negatively affect our ability to obtain additional financing or the interest rate, fees and other 
terms  associated  with  such  additional  financing.  Further,  if  we  are  unable  to  maintain  credit  ratings  of  “Ba2”  or  better  from 
Moody’s and “BB” or better from S&P, the Investment Grade Period under our Credit Facility will automatically terminate and 
cause our Credit Facility to once again be secured by a first lien on substantially all of our oil and natural gas properties and by 
a pledge of the equity interests in our subsidiaries. These and other impacts of a downgrade in our credit ratings could have a 
material adverse effect on our business, financial condition and results of operations.  

As of the filing of this Annual Report on Form 10-K, no changes in our credit ratings have occurred; however, we cannot be 

assured that our credit ratings will not be downgraded in the future. 

Book capitalization and current ratio. Our net book capitalization at December 31, 2018 was $23.0 billion, consisting of 
debt of $4.2 billion and stockholders’ equity of $18.8 billion. Our net book capitalization at December 31, 2017 was $11.6 billion, 
consisting of debt of $2.7 billion and stockholders’ equity of $8.9 billion. Our ratio of net debt to net book capitalization was 18 
percent and 23 percent at December 31, 2018 and 2017, respectively. Our ratio of current assets to current liabilities was 1.04 
to 1.0 at December 31, 2018 as compared to 0.51 to 1.0 at December 31, 2017.  

Inflation and changes in prices. Our revenues, the value of our assets and our ability to obtain bank financing or additional 
capital on attractive terms have been and will continue to be affected by changes in commodity prices and the costs to produce 
our reserves. Commodity prices are subject to significant fluctuations that we are unable to control or predict. During the year 
ended  December  31,  2018,  we  received  an  average  of  $56.22  per  barrel  of  oil  and  $3.40  per  Mcf  of  natural  gas  before 
consideration of commodity derivative contracts compared to $48.13 and $39.90 per barrel of oil and $3.07 and $2.23 per Mcf 
of  natural  gas in the  years ended  December 31,  2017  and 2016,  respectively.  Although certain of  our costs are affected  by 
general inflation, inflation does not normally have a significant effect on our business.

Critical Accounting Policies, Practices and Estimates 

Our historical consolidated financial statements and related notes to consolidated financial statements contain information 
that is pertinent to our management’s discussion and analysis of financial condition and results of operations. Preparation of 
financial  statements  in  conformity  with  accounting  principles  generally  accepted  in  the  United  States  requires  that  our 
management make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenues and 
expenses, and the disclosure of contingent assets and liabilities. However, the accounting principles used by us generally do 
not change our reported cash flows or liquidity. Interpretation of the existing rules must be done and judgments made on how 
the specifics of a given rule apply to us. 

In management’s opinion, the more significant reporting areas impacted by management’s judgments and estimates are 
the  choice  of  accounting  method  for  oil  and  natural  gas  activities,  oil  and  natural  gas  reserve  estimation,  asset  retirement 
obligations,  impairment  of  long-lived  assets,  valuation  of  stock-based  compensation,  valuation  of  business  combinations, 
accounting  and  valuation  of  nonmonetary  transactions,  goodwill  impairment,  litigation  and  environmental  contingencies, 
valuation of financial derivative instruments, uncertain tax positions and income taxes. Management’s judgments and estimates 
in these areas are based on information available from both internal and external sources, including engineers, geologists and 
historical experience in similar matters. Actual results could differ from the estimates as additional information becomes known. 

Successful Efforts Method of Accounting 

We utilize the successful efforts method of accounting for our oil and natural gas exploration and development activities. 
Under this method, exploration expenses, including geological and geophysical costs, lease rentals and exploratory dry holes, 
are charged against income as incurred. Costs of successful wells and related production equipment, undeveloped leases and 
developmental dry holes are capitalized. Exploratory drilling costs are initially capitalized, but are charged to expense if and 
when a well is determined not to have found proved reserves. Generally, a gain or loss is recognized when producing fields are 
sold. This accounting method may yield significantly different results than the full cost method of accounting. 

The application of the successful efforts method of accounting requires management’s judgment to determine the proper 
designation of wells as either developmental or exploratory, which will ultimately determine the proper accounting treatment of 
costs of dry holes. Once a well is drilled, the determination that proved reserves have been discovered may take considerable 
time,  and  requires  both  judgment  and  application  of  industry  experience.  The  evaluation  of  oil  and  natural  gas  leasehold 
acquisition costs included in unproved properties requires management’s judgment to estimate the fair value of such properties. 
Drilling activities in an area by other companies may also effectively impair our leasehold positions. 

Depletion  of  capitalized  drilling  and  development  costs  of  oil  and  natural  gas  properties  is  computed  using  the  unit-of-
production method on total estimated proved developed oil and natural gas reserves. Depletion of producing leaseholds is based 
on  the  unit-of-production  method  using  our  total  estimated  proved  reserves.  In  arriving  at  rates  under  the  unit-of-production 
method,  the  quantities  of  recoverable  oil  and  natural  gas  are  established  based  on  estimates  made  by  our  geologists  and 
engineers and independent engineers. Service properties, equipment and other assets are depreciated using the straight-line 
method over estimated useful lives of two to 39 years.

Oil and Natural Gas Reserves and Standardized Measure of Discounted Net Future Cash Flows 

This report presents estimates of our proved reserves as of December 31, 2018, which have been prepared and presented 
in accordance with SEC guidelines. The pricing that was used for estimates of our reserves as of December 31, 2018 was based 
on the 12-month unweighted average of the first-day-of-the-month WTI posted price of $62.04 per Bbl for oil and Henry Hub 
spot natural gas price of $3.10 per MMBtu for natural gas. 

Our independent engineers and technical staff prepare the estimates of our oil and natural gas reserves and associated 
future net cash flows. Even though our independent engineers and technical staff are knowledgeable and follow authoritative 
guidelines for estimating reserves, they must make a number of subjective assumptions based on professional judgments in 
developing the reserve estimates. Reserve estimates are updated at least annually and consider recent production levels and 
other  technical  information  about  each  field.  Periodic  revisions  to  the  estimated  reserves  and  future  net  cash  flows  may  be 
necessary  as  a  result  of  a  number  of  factors,  including  reservoir  performance,  new  drilling,  oil  and  natural  gas  prices,  cost 
changes, technological advances, new geological or geophysical data, or other economic factors. We cannot predict the amounts 
or timing of future reserve revisions. If such revisions are significant, they could significantly alter future depletion and result in 
impairment of long-lived assets that may be material. 

It should not be assumed that the Standardized Measure included in this report as of December 31, 2018 is the current 
market  value  of  our  estimated  proved  reserves.  In  accordance  with  SEC  requirements,  we  based  the  2018  Standardized 
Measure on the 12-month unweighted average of the first-day-of-the-month pricing for oil and natural gas and prevailing costs 
on the date of the estimate. Actual future prices and costs may be materially higher or lower than the prices and costs utilized 
in the estimate. See “Item 1A. Risk Factors” and “Item 2. Properties” for additional information regarding estimates of proved 
reserves. 

Our estimates of proved reserves materially impact depletion expense. If the estimates of proved reserves decline, the rate 
at which we record depletion expense will increase, reducing future earnings. Such a decline may result from lower commodity 
prices,  which  may  make  it  uneconomical  to  drill  for  and  produce  higher  cost  fields.  In  addition,  a  decline  in  proved  reserve 
estimates may impact the outcome of our assessment of our proved properties for impairment. 

Asset Retirement Obligations 

There are legal obligations associated with the retirement of long-lived assets that result from the acquisition, construction, 
development and the normal operation of a long-lived asset. The primary impact of this relates to oil and natural gas wells on 
which we have a legal obligation to plug and abandon. We record the fair value of a liability for an asset retirement obligation in 
the period in which it is incurred and, generally, a corresponding increase in the carrying amount of the related long-lived asset. 
The determination of the fair value of the liability requires us to make numerous judgments and estimates, including judgments 
and estimates related to future costs to plug and abandon wells, future inflation rates and estimated lives of the related assets. 
When the judgments used to estimate the initial fair value of the asset retirement obligation change, an adjustment is recorded 
to both the obligation and the carrying amount of the related long-lived asset. Historically, there have been no significant revisions 
to our initial estimates once future results became known. See Note 6 of the Notes to Consolidated Financial Statements included 
in “Item 8. Financial Statements and Supplementary Data” for additional information regarding our asset retirement obligations. 

Impairment of Long-Lived Assets 

All of our long-lived assets are monitored for potential impairment when circumstances indicate that the carrying value of 
an asset may be greater than management’s estimates of its future net cash flows, including cash flows from proved reserves, 
risk-adjusted probable and possible reserves, and integrated assets. If the carrying value of the long-lived assets exceeds the 
sum of estimated undiscounted future net cash flows, an impairment loss is recognized for the difference between the estimated 
fair value and the carrying value of the assets. The evaluations involve a significant amount of judgment since the results are 
based on estimated future events, such as future sales prices for oil and natural gas, future costs to produce these products, 
estimates of future oil and natural gas reserves to be recovered and the timing thereof, the economic and regulatory climates, 
cash flows from integrated assets and other factors. The need to test an asset for impairment may result from significant declines 
in  sales  prices  or  downward  revisions  in  estimated  quantities  of  oil  and  natural  gas  reserves.  Any  assets  held  for  sale  are 
reviewed  for  impairment  when  we  approve  the  plan  to sell.  Estimates  of  anticipated  sales  prices  are  highly  judgmental  and 
subject  to  material  revision  in  future  periods.  At  December 31,  2018,  our  estimates  of  commodity  prices  for  purposes  of 
determining undiscounted future cash flows, which are based on the NYMEX strip, ranged from a 2019 price of $47.09 per barrel 
of oil increasing to a 2025 price of $53.10 per barrel of oil. Natural gas prices ranged from a 2019 price of $2.78 per Mcf of 
natural gas decreasing to a 2021 price of $2.61 per Mcf then rising to a 2025 price of $2.90 per Mcf of natural gas. Both oil and 
natural gas commodity prices for this purpose were held flat after 2025. We did not recognize an impairment charge during the 
year ended December 31, 2018. 

It is reasonably possible that the estimates of undiscounted future net cash flows of our long-lived assets may change in 
the future resulting in the need to impair carrying values. We estimate that if the future oil and natural gas prices used in this 
analysis, and noted above, would have been approximately 10 percent lower at December 31, 2018 with no other changes in 
capital costs, operating costs, price differentials or reserve performance curves, the carrying amount of our Yeso field would 

67 

    
  
 
 
 
 
  
  
  
 
have exceeded the expected undiscounted future net cash flow and an impairment of approximately $800 million would have 
been recorded. The impairment would have been the result of certain downward revisions to our proved reserves in the Yeso 
field during 2018. Other assumptions such as operating costs, well and reservoir performance, severance and ad valorem taxes 
and operating and development plans would likely change given a change in oil and natural gas prices. However, we did not 
estimate  the  correlation  between  these  assumptions  and  any  estimated  commodity  price  change,  and  these  and  other 
assumptions may  worsen  or partially  mitigate some  of  the effects  of  a  reduction  in  commodity  prices, including  the ultimate 
impact and amount of any potential impairment charge. As a result, we are unable to predict with certainty whether or not a 
decline in commodity prices alone will or will not cause us to recognize an impairment charge in a particular field or the magnitude 
of any such impairment charge. We additionally note that there may be changes to both drilling and completion designs that 
affect the volume curves, capital costs estimates and the amount of proved undeveloped locations that can be recorded, each 
of which will affect management’s estimates of future cash flows. See Notes 2 and 8 of the Notes to Consolidated Financial 
Statements included in “Item 8. Financial Statements and Supplementary Data” for additional information on impairments of 
long-lived assets. 

Unproved  oil  and  natural  gas  properties  are  periodically  assessed  for  impairment  by  considering  future  drilling  and 
exploration plans, results of exploration activities, commodity price outlooks, planned future sales and expiration of all or a portion 
of  the  projects.  During  the  years  ended  December  31,  2018,  2017  and  2016,  we  recognized  expense  of  approximately 
$35 million, $27 million and $50 million, respectively, related to abandoned and expiring acreage, which is included in exploration 
and abandonments expense in the accompanying consolidated statements of operations. 

Valuation of Stock-Based Compensation 

In accordance with GAAP, we calculate the fair value of stock-based compensation using various valuation methods. The 
valuation methods require the use of estimates to derive the inputs necessary to determine fair value. We utilize (i) the average 
of the high and low stock price on the date of grant for the fair value of restricted stock awards and (ii) the Monte Carlo simulation 
method  for  the  fair  value  of  performance  unit  awards.  The  significant  assumptions  used  in  these  models  include  expected 
volatility, expected term, risk-free interest rate, forfeiture rate, and the probability of meeting performance targets. Each of these 
valuation methods were chosen as management believes they give the best estimate of fair value for the respective stock-based 
awards.  See  Note  7  of  the  Notes  to  Consolidated  Financial  Statements  included  in  “Item 8.  Financial  Statements  and 
Supplementary Data” for more information regarding our stock-based compensation. 

Valuation of Business Combinations 

In connection with a purchase business combination, the acquiring company must record assets acquired and liabilities 
assumed  based  on  fair  values  as  of  the  acquisition  date. Deferred  taxes  must  be recorded  for  any  differences  between  the 
assigned values and tax bases of assets and liabilities. Any excess of purchase price over amounts assigned to assets and 
liabilities is recorded as goodwill. The amount of goodwill recorded in any particular business combination can vary significantly 
depending upon the value attributed to assets acquired and liabilities assumed. 

In estimating the fair values of assets acquired and liabilities assumed, we make various assumptions. The most significant 
assumptions related to the estimated fair values assigned to proved and unproved oil and natural gas properties and integrated 
assets. To estimate the fair values of these properties, we utilize estimates of oil and natural gas reserves. We make future price 
assumptions to apply to the estimated reserves quantities acquired and estimate future operating and development costs to 
arrive at estimates of future net cash flows. For estimated proved reserves, the future net cash flows are discounted using a 
market-based weighted average cost of capital rate determined appropriate at the time of the acquisition. The market-based 
weighted average cost of capital rate is subject to additional project-specific risking factors. To estimate the fair value of unproved 
properties, we apply risk-weighting factors of the future net cash flows of unproved reserves, or we may evaluate acreage values 
through recent market transactions in the area. 

Estimated  fair  values  assigned  to assets  acquired  can  have  a significant  effect  on  results  of  operations  in  the  future. A 
higher fair value assigned to a property results in a higher depletion expense, which results in lower net earnings. Fair values 
are  based  on  estimates  of  future  commodity  prices,  reserves  quantities,  operating  expenses  and  development  costs.  This 
increases the likelihood of impairment if future commodity prices or reserves quantities are lower than those originally used to 
determine fair value or if future operating expenses or development costs are higher than those originally used to determine fair 
value. Impairment would have no effect on cash flows but would result in a decrease in net income for the period in which the 
impairment is recorded. Historically, we have had no material revisions to valuations of business combinations once the valuation 
estimate was finalized. 

Accounting and Valuation of Nonmonetary Transactions 

In connection with nonmonetary transactions, which include exchanges of producing and non-producing assets, we must 
evaluate  the  transaction  to  determine  appropriate  accounting  treatment.  In  general,  the  basic  principle  of  accounting  for 
nonmonetary  transactions  is  based  on  the  fair  values  involved,  which  is  the  same basis  used in  monetary  transactions  and 
results in the recognition of gains and losses. However, certain nonmonetary transactions meet criteria that require modification 
of  the  basic  principle  that  necessitate  recording  values  based  on  historical  book  value.  We  determine  the  treatment  of 

68 

    
 
 
 
 
 
 
 
 
 
nonmonetary transactions based on the individual facts and circumstances of each transaction. In cases where nonmonetary 
transactions  are  recorded  at  fair  value,  we  make  various  assumptions.  The  most  significant  assumptions  are  related  to  the 
estimated fair values assigned to proved and unproved oil and natural gas properties, similar to our valuation of the fair value of 
oil and natural gas assets acquired during a business combination described above. Any resulting difference between the fair 
value of the assets involved and their carrying value is recorded as a gain or loss in the consolidated statement of operations. 

Estimated fair values assigned to assets exchanged can have a significant effect on our results of operations in the future. 
If future commodity prices or reserves quantities are lower than those originally used to determine fair value or if future operating 
expenses or development costs are higher than those originally used to determine fair value, we would record an impairment 
loss for the amount by which the carrying amount of the asset exceeds the estimated fair value. Impairment would have no effect 
on cash flows but would result in a decrease in net income for the period in which the impairment is recorded. 

Goodwill Impairment 

Goodwill is not amortized but assessed for impairment on an annual basis, or more frequently if indicators of impairment 
exist. Impairment tests, which involve the use of estimates related to the fair market value of the business operations with which 
goodwill is associated, is performed as of July 1 of each year. As we operate as a single operating segment and a single reporting 
unit,  we  evaluate  goodwill  for  impairment  based  on  an  evaluation  of  the  fair  value  of  the  company  as  a  whole.  There  is 
considerable judgment involved in estimating fair values, including, among other things, determining the control premium when 
using the market approach in determining the fair value. To establish a reasonable control premium, we consider the premiums 
paid in recent market acquisitions and analyze current industry, market and economic conditions along with other factors or 
available information specific to our business. See Notes 2 and 4 of the Notes to Consolidated Financial Statements included in 
“Item 8. Financial Statements and Supplementary Data” for more information regarding goodwill. 

Litigation and Environmental Contingencies 

We make judgments and estimates in recording liabilities for ongoing litigation and environmental remediation. Actual costs 
can vary from such estimates for a variety of reasons. The costs to settle litigation can vary from estimates based on differing 
interpretations of laws and opinions and assessments on the amount of damages. Similarly, environmental remediation liabilities 
are subject to change because of changes in laws and regulations, developing information relating to the extent and nature of 
site contamination and improvements in technology. A liability is recorded for these types of contingencies if we determine the 
loss  to  be  both  probable  and  reasonably  estimable.  If  we  are  unable  to  reasonably  estimate  an  amount  but  we  are  able  to 
estimate  a  range  of  reasonably  possible  amounts,  then  the  low  end  of  the  range  is  recorded.  See  Note  11  of  the  Notes  to 
Consolidated  Financial  Statements included  in  “Item 8.  Financial  Statements  and  Supplementary  Data”  for more  information 
regarding our commitments and contingencies. 

Valuation of Financial Derivatives  

In order to reduce commodity price uncertainty and increase cash flow predictability relating to the marketing of our oil and 
natural  gas,  we  enter  into  commodity  price  hedging  arrangements  with  respect  to  a  portion  of  our  expected  production.  In 
addition, we have used derivative instruments in connection with acquisitions and certain price-sensitive projects. Management 
exercises significant judgment in determining the types of instruments to be used, production volumes to be hedged, prices at 
which to hedge and the counterparties’ creditworthiness. All derivative instruments are reflected at fair value in our consolidated 
balance sheets. 

Our open commodity derivative instruments were in a net asset position with a fair value of $695 million at December 31, 
2018. In order to determine the fair value at the end of each reporting period, we compute discounted cash flows for the duration 
of each commodity derivative instrument using the terms of the related contract. Inputs consist of published forward commodity 
price curves as of the date of the estimate. We compare these prices to the price parameters contained in our hedge contracts 
to determine estimated future cash inflows or outflows. We then discount the cash inflows or outflows using a combination of 
published LIBOR rates and Eurodollar futures rates. The fair values of our commodity derivative assets and liabilities include a 
measure of credit risk based on average published yields by credit rating.  

Changes in the fair values of our commodity derivative instruments have a significant impact on our net income because 
we follow mark-to-market accounting and recognize all gains and losses on such instruments in earnings in the period in which 
they occur. For the year ended December 31, 2018, we reported a $832 million gain on commodity derivative instruments. 

We  compare  our  estimates  of  the  fair  values  of  our  commodity  derivative  instruments  with  those  provided  by  our 

counterparties. There have been no significant differences. 

Income Taxes  

On December 22, 2017, the President of the United States signed the TCJA into law, which enacted significant changes to 
the federal income tax laws. According to ASC 740, “Income Taxes,” a company is required to record the effects of an enacted 
tax  law  or  rate  change in  the period  of  enactment.  Based  on  the  comprehensiveness  of TCJA  and  the challenges  faced  by 

69 

    
 
 
 
 
 
 
 
 
 
 
 
 
calendar year-end registrants to complete the accounting for the income tax effects of the TCJA in the period of enactment, the 
SEC issued SAB 118 “Income Tax Accounting Implications of the Tax Cuts and Jobs Act,” which allowed companies to report 
provisional amounts when based on reasonable estimates and to adjust these amounts during a measurement period of up to 
one year. 

We elected to apply SAB 118 and recorded provisional amounts of our income tax balances in our consolidated financial 
statements at December 31, 2017. We calculated our best estimate of the impact of the TCJA, including the federal statutory 
tax rate change noted below, in our 2017 income tax provision in accordance with our understanding of the TCJA and recorded 
a  $398  million  decrease  to  our  income  tax  provision  at  December  31,  2017.  The  provisional  amount  related  to  the  re-
measurement of certain deferred tax assets and liabilities based on the rates at which they are expected to reverse in the future. 
At  December  31,  2018,  the  Company  completed  its  accounting  for  all  of  the  enactment-date  tax  effects  of  the  TCJA  and 
recognized an adjustment of $7 million to the provisional amount recorded at December 31, 2017. This adjustment was primarily 
related to the deductibility of certain performance-based compensation based on additional available regulatory and interpretive 
guidance. 

On July 19, 2018, we completed the RSP Acquisition. For federal income tax purposes, the transaction qualified as a tax-
free merger whereby we acquired carryover tax basis in RSP’s assets and liabilities. As of December 31, 2018, we recorded an 
opening balance sheet deferred tax liability of $515 million based on our assessment of the carryover tax basis, which includes 
a deferred tax asset related to tax attributes acquired from RSP. The acquired income tax attributes primarily consist of NOLs 
and research and development credits that are subject to an annual limitation under Internal Revenue Code Section 382. The 
Company expects that these tax attributes will be fully utilized prior to expiration. 

Our provision for income taxes includes both federal and state taxes of the jurisdictions in which we operate. We estimate 
our overall tax rate using a combination of the enacted federal statutory tax rate, which decreased from 35 percent to 21 percent 
effective January 1, 2018 as a result of the TCJA, and a blend of enacted state tax rates. Acquisitions or dispositions of assets 
and changes in our drilling plan by tax jurisdiction could change the apportionment of our state taxes, which would impact our 
overall tax rate. 

We recognize  the  tax  benefit from  an  uncertain  tax  position  only  if  it  is more likely  than  not  that  the  tax  position  will  be 
sustained upon examination by the taxing authorities, based upon the technical merits of the position. At December 31, 2018, 
we had unrecognized tax benefits of approximately $63 million, primarily related to research and development credits. If all or a 
portion of the unrecognized tax benefit is sustained upon examination by the taxing authorities, the tax benefit will be recognized 
as a reduction to our deferred tax liability and will affect our effective tax rate in the period it is recognized. The assessment of 
potential uncertain tax positions requires a significant amount of judgment and are reviewed and adjusted on a periodic basis. 

Our federal and state income tax returns are not prepared or filed before the consolidated financial statements are prepared; 
therefore, we estimate the tax basis of our assets and liabilities, which are based on numerous judgments and assumptions 
inherent in the determination of future taxable income, at the end of each period as well as the effects of tax rate changes and 
tax credits. Adjustments related to these estimates are recorded in our tax provision in the period in which we finalize our income 
tax returns. Historically, we have had no significant changes as a result of filing our tax returns. Material changes to our tax 
accruals and uncertain tax positions may occur in the future based on audits, changes in legislation or resolution of pending 
matters.

Supplementary  Data”  for  additional  information  regarding  our  current  year  income  tax  expense,  deferred  tax  balances  and 
uncertain tax positions.

Item 7A.  Quantitative and Qualitative Disclosures About Market Risk 

We are exposed to a variety of market risks, including credit risk, commodity price risk and interest rate risk. We address 
these risks through a program of risk management which includes the use of derivative instruments. The following quantitative 
and  qualitative  information  is provided about  financial  instruments  to  which  we  are  a  party  at  December 31, 2018,  and from 
which we may incur future gains or losses from changes in market interest rates or commodity prices and losses from extension 
of credit. We do not enter into derivative or other financial instruments for speculative or trading purposes. 

Hypothetical  changes  in  interest  rates  and commodity  prices  chosen  for  the  following  estimated  sensitivity  analysis  are 
considered to be reasonably possible near-term changes generally based on consideration of past fluctuations for each risk 
category. However, since it is not possible to accurately predict future changes in interest rates and commodity prices, these 
hypothetical changes may not necessarily be an indicator of probable future fluctuations. 

Credit  risk. We  monitor  our  risk  of  loss  due  to  non-performance  by  counterparties  of  their  contractual  obligations.  Our 
principal exposure to credit risk is through the sale of our oil and natural gas production, which we market to energy marketing 
companies and refineries and, to a lesser extent, our derivative counterparties. We monitor our exposure to these counterparties 
primarily by reviewing credit ratings, financial statements and payment history. We extend credit terms based on our evaluation 
of each counterparty’s creditworthiness.  

We have entered into International Swap Dealers Association Master Agreements (“ISDA Agreements”) with each of our 
derivative counterparties. The terms of the ISDA Agreements provide us and the counterparties with rights of set-off upon the 
occurrence of defined acts of default by either us or a counterparty to a derivative, whereby the party not in default may set off 
all derivative liabilities owed to the defaulting party against all derivative asset receivables from the defaulting party. See Note 9 
of  the  Notes  to  Consolidated  Financial  Statements  included  in  “Item 8.  Financial  Statements  and  Supplementary  Data”  for 
additional information regarding our derivative activities. 

Commodity price risk.  We are exposed to market risk as the prices of our commodities are subject to fluctuations resulting 
from changes in supply and demand. To reduce our exposure to changes in the prices of our commodities, we have entered 
into, and may in the future enter into, additional commodity price risk management arrangements for a portion of our oil and 
natural gas production. The agreements that we have entered into generally have the effect of providing us with a fixed price for 
a portion of our expected future oil and natural gas production over a fixed period of time. Our commodity price risk management 
arrangements are recorded at fair value and thus changes to the future commodity prices will have an impact on our earnings. 
The following table sets forth the hypothetical impact on the fair value of the commodity price risk management arrangements 
from an average increase and decrease in the commodity price of $5.00 per Bbl of oil and $0.50 per MMBtu of natural gas from 
the average commodity prices for the years ended December 31, 2018 and 2017:

Our  commodity  price  risk  management  arrangements  expose  us  to  risk  of  non-performance  by  the  counterparty  to  the 
agreements. Our exposure to the risk of non-performance is diversified over large, investment grade financial institutions. In 
addition, we have master netting agreements with the counterparties that allow for offsetting payables against receivables from 
separate  contracts  with  the  same  counterparty.  At  December  31,  2018,  the  counterparties  to  our  commodity  price  risk 
management arrangements include fourteen financial institutions, the majority of which are lenders under our Credit Facility. 
Risk of non-performance is considered when determining the fair value of our commodity price risk management arrangements. 
The  fair  value  adjustment  for  non-performance  risk  was  immaterial  at  December  31,  2018.  If  at  any  point  a  counterparty’s 
financial position deteriorates, such deterioration could have a significant impact on the collectability of that counterparty’s related 
commodity price risk management arrangement asset. See Note 13 of the Notes to Consolidated Financial Statements included 
in  “Item  8.  Financial  Statements  and  Supplementary  Data”  for  additional  information  regarding  our  significant  derivative 
counterparties. 

At December 31, 2018, we had (i) oil price swaps and oil costless collars covering future oil production from January 1, 
2019 through December 31, 2020 and (ii) oil basis swaps covering our Midland to Cushing basis differential from January 1, 
2019 to December 31, 2021. The NYMEX oil price at December 31, 2018 was $45.41 per Bbl. At February 15, 2019, the NYMEX 
oil price was $55.59 per Bbl.

At December 31, 2018, we had natural gas price swaps that settle on a monthly basis covering future natural gas production 
from January 1, 2019 to December 31, 2020. The NYMEX natural gas price at December 31, 2018 was $2.94 per MMBtu. At 
February 15, 2019, the NYMEX natural gas price was $2.63 per MMBtu. See Note 9 of the Notes to Consolidated Financial 
Statements included in “Item 8. Financial Statements and Supplementary Data” for additional information on our commodity 
derivative instruments. 

A decrease in the average forward NYMEX oil and natural gas prices below those at December 31, 2018 would increase 
the fair value asset of our commodity derivative contracts from their recorded balances at December 31, 2018. Changes in the 
recorded  fair  value  of  our  commodity  derivative  contracts  are  marked  to  market  through  earnings  as  gains  or  losses. The 
potential increase in our fair value asset would be recorded in earnings as a gain. However, an increase in the average forward 
NYMEX oil and natural gas prices above those at December 31, 2018 would decrease the fair value asset of our commodity 
derivative contracts from their recorded balances at December 31, 2018. The potential decrease in our fair value asset would 
be recorded in earnings as a loss. We are currently unable to estimate the effects on the earnings of future periods resulting 
from changes in the market value of our commodity derivative contracts. 

We recorded a gain on derivatives of $832 million for the year ended December 31, 2018, compared to a loss of $126 
million for the year ended December 31, 2017. The largest factor in the change from 2017 to 2018 related to the change in 
commodity future price curves at the respective measurement and settlement periods. 

The fair value of our derivative instruments is determined based on our valuation models. We did not change our valuation 
method during the year ended December 31, 2018. See Note 9 of the Notes to Consolidated Financial Statements included in 
“Item  8.  Financial  Statements  and  Supplementary  Data”  for  additional  information  regarding  our  derivative  instruments.  The 
following  table  reconciles  the  changes  that  occurred  in  the  fair  values  of  our  derivative  instruments  during  the  year  ended 
December 31, 2018:

(a)  At inception, new derivative contracts entered into by us have no intrinsic value. 
(b)  Represents the fair values of open derivative contracts subject to market risk. 

Interest rate risk.  Our exposure to changes in interest rates relates primarily to debt obligations. We manage our interest 
rate exposure by limiting our variable-rate debt to a certain percentage of total capitalization and by monitoring the effects of 
market changes in interest rates. To reduce our exposure to changes in interest rates we may, in the future, enter into interest 
rate risk management arrangements for a portion of our outstanding debt. The agreements that we have entered into generally 
have  the  effect  of  providing  us  with  a  fixed  interest  rate  for  a  portion  of  our  variable-rate  debt. We  may  utilize  interest  rate 
derivatives to alter interest rate exposure in an attempt to reduce interest rate expense related to existing debt issues. Interest 
rate derivatives are used solely to modify interest rate exposure and not to modify the overall leverage of the debt portfolio. We 
had no outstanding interest rate derivative contracts at December 31, 2018. We are exposed to changes in interest rates as a 
result of our Credit Facility, and the terms of our Credit Facility require us to pay higher interest rate margins as our credit ratings 
decrease.  

We had total indebtedness of $242 million outstanding under our Credit Facility at December 31, 2018. The impact of a one 
percent increase in interest rates on this amount of debt would result in increased annual interest expense of approximately $2 
million.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

Board of Directors and Stockholders 
Concho Resources Inc. 

Opinion on the financial statements  
We  have  audited  the  accompanying  consolidated  balance  sheets  of  Concho  Resources  Inc.  (a  Delaware  corporation)  and 
subsidiaries (the “Company”) as of December 31, 2018 and 2017, the related consolidated statements of operations, changes 
in stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2018, and the related notes 
(collectively  referred  to  as  the  “financial  statements”).  In  our  opinion,  the  financial  statements  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.  

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(“PCAOB”), the Company’s internal control over financial reporting as of December 31, 2018, based on criteria established in 
the  2013  Internal  Control—Integrated  Framework  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway 
Commission (“COSO”), and our report dated February 20, 2019 expressed an unqualified opinion. 

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

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform 
the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due 
to  error  or  fraud.  Our  audits  included  performing  procedures  to  assess  the  risks  of  material  misstatement  of  the  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 supporting the amounts and disclosures in the 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 financial statements. We believe that our audits provide a reasonable basis for our opinion.

Net wells  

PV-10 

The total of fractional working interests owned in gross wells. 

When used with respect to oil and natural gas reserves, PV-10 means the estimated future 
gross  revenue  to  be  generated  from  the  production  of  proved  reserves,  net  of  estimated 
production and future development and abandonment costs, using prices and costs in effect 
at  the  determination  date,  before  income  taxes,  and  without  giving  effect  to  non-property-
related expenses except for specific general and administrative expenses incurred to operate 
the properties, discounted to a present value using an annual discount rate of 10 percent. PV-
10 is a non-GAAP financial measure. 

Productive wells  

Wells  that  produce  commercial  quantities  of  hydrocarbons,  exclusive  of  their  capacity  to 
produce at a reasonable rate of return. 

Proved developed reserves 

Proved developed reserves are proved reserves that can be expected to be recovered: 

Proved reserves 

(i) 

through existing wells with existing equipment and operating methods or in which the 
cost of the required equipment is relatively minor compared to the cost of a new well; 
and  

(ii) 

through installed extraction equipment and infrastructure operational at the time of the 
reserve estimate if the extraction is by means not involving a well. 

Supplemental definitions from the 2007 Petroleum Resources Management System: 

Proved  Developed  Producing  Reserves  –  Developed  Producing  Reserves  are 
expected to be recovered from completion intervals that are open and producing at the 
time of the estimate. Improved recovery reserves are considered producing only after 
the improved recovery project is in operation. 

Proved  Developed  Non-Producing  Reserves  –  Developed  Non-Producing  Reserves 
include  shut-in  and  behind-pipe  Reserves.  Shut-in  Reserves  are  expected  to  be 
recovered from (1) completion intervals which are open at the time of the estimate but 
which have not yet started producing, (2) wells which were shut-in for market conditions 
or pipeline connections, or (3) wells not capable of production for mechanical reasons. 
Behind-pipe Reserves are expected to be recovered from zones in existing wells which 
will require additional completion work or future recompletion prior to start of production. 
In  all  cases,  production  can  be  initiated  or  restored  with  relatively  low  expenditure 
compared to the cost of drilling a new well. 

Proved reserves are those quantities of oil and natural gas, which, by analysis of geoscience 
and  engineering  data,  can  be  estimated  with  reasonable  certainty  to  be  economically 
producible—from a given date forward, from known reservoirs, and under existing economic 
conditions,  operating  methods,  and  government  regulations—prior  to  the  time  at  which 
contracts  providing  the  right  to  operate  expire,  unless  evidence  indicates  that  renewal  is 
reasonably certain, regardless of whether deterministic or probabilistic methods are used for 
the estimation. The project to extract the hydrocarbons must have commenced or the operator 
must be reasonably certain that it will commence the project within a reasonable time. 

(i) 

The area of the reservoir considered as proved includes: 

(A)  the area identified by drilling and limited by fluid contacts, if any, and 

(B)  adjacent  undrilled  portions  of  the  reservoir  that  can,  with  reasonable 
certainty,  be judged  to be  continuous  with  it and  to  contain  economically 
producible  oil  or  natural  gas  on  the  basis  of  available  geoscience  and 
engineering data. 

(ii)  

In the absence of data on fluid contacts, proved quantities in a reservoir are limited by 
the  lowest  known  hydrocarbons  (“LKH”)  as  seen  in  a  well  penetration  unless 
geoscience,  engineering,  or  performance  data  and  reliable technology  establishes  a 
lower contact with reasonable certainty. 

(iii)  Where  direct  observation  from  well  penetrations  has  defined  a  highest  known  oil 
(“HKO”) elevation and the potential exists for an associated natural gas cap, proved oil 

76 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
reserves  may  be  assigned  in  the  structurally  higher  portions  of  the  reservoir  only  if 
geoscience,  engineering,  or  performance  data  and  reliable  technology  establish  the 
higher contact with reasonable certainty. 

(iv)   Reserves  which  can  be  produced  economically  through  application  of  improved 
recovery  techniques  (including,  but  not  limited  to,  fluid  injection)  are  included  in  the 
proved classification when: 

(A)  successful  testing  by  a  pilot  project  in  an  area  of  the  reservoir  with 
properties no more favorable than in the reservoir as a whole, the operation 
of an installed program in the reservoir or an analogous reservoir, or other 
evidence using reliable technology establishes the reasonable certainty of 
the engineering analysis on which the project or program was based; and 

(B)  the project has been approved for development by all necessary parties and 

entities, including governmental entities. 

(v) 

Existing economic conditions include prices and costs at which economic producibility 
from a reservoir is to be determined. The price shall be the average price during the 
12-month period prior to the ending date of the period covered by the report, determined 
as an unweighted arithmetic average of the first-day-of-the-month price for each month 
within such period, unless prices are defined by contractual arrangements, excluding 
escalations based upon future conditions. 

Proved undeveloped reserves   Proved undeveloped oil and natural gas reserves are proved reserves that are expected to be 
recovered from new wells on undrilled acreage, or from existing wells where a relatively major 
expenditure is required for recompletion. 

(i) 

(ii) 

Reserves on undrilled acreage shall be limited to those directly offsetting development 
spacing areas that are reasonably certain of production when drilled, unless evidence 
using  reliable  technology  exists  that  establishes  reasonable  certainty  of  economic 
producibility at greater distances. 

Undrilled  locations  can  be  classified  as  having  undeveloped  reserves  only  if  a 
development plan has been adopted indicating that they are scheduled to be drilled 
within five years from initial booking, unless the specific circumstances justify a longer 
time. 

Recompletion 

The addition of production from another interval or formation in an existing wellbore. 

Reservoir 

Spacing 

Standardized Measure 

A formation beneath the surface of the earth from which hydrocarbons may be present. Its 
make-up is sufficiently homogenous to differentiate it from other formations. 

The distance between wells producing from the same reservoir. Spacing is expressed in terms 
of acres, e.g., 40-acre spacing, and is established by regulatory agencies. 

The  present  value  (discounted  at  an  annual  rate  of  10  percent)  of  estimated  future  net 
revenues to be generated from the production of proved reserves net of estimated income 
taxes associated with such net revenues, as determined in accordance with FASB guidelines, 
without  giving  effect  to  non-property  related  expenses  such  as  indirect  general  and 
administrative  expenses,  and  debt  service  or  to  depreciation,  depletion  and  amortization. 
Standardized measure does not give effect to derivative transactions. 

Undeveloped acreage 

Acreage owned or leased on which wells have not been drilled or completed to a point that 
would permit the production of economic quantities of oil and natural gas regardless of whether 
such acreage contains proved reserves. 

Wellbore 

Working interest 

The hole drilled by the bit that is equipped for oil or natural gas production on a completed 
well. Also called a well or borehole. 

The right granted to the lessee of a property to explore for and to produce and own oil, natural 
gas, or other minerals. The working interest owners bear the exploration, development, and 
operating costs on either a cash, penalty, or carried basis. 

Workover 

Operations on a producing well to restore or increase production.

Concho Resources Inc. 
Notes to Consolidated Financial Statements 
December 31, 2018, 2017 and 2016 

Note 1. Organization and nature of operations 

Concho Resources Inc. (the “Company”) is a Delaware corporation formed on February 22, 2006. The Company’s principal 
business is the acquisition, development, exploration and production of oil and natural gas properties primarily located in the 
Permian Basin of Southeast New Mexico and West Texas. 

Note 2. Summary of significant accounting policies 

Principles of consolidation. The consolidated financial statements of the Company include the accounts of the Company 
and its 100 percent owned subsidiaries. The consolidated financial statements also included the accounts of a variable interest 
entity (“VIE”) where the Company was the primary beneficiary of the arrangements until the VIE structure dissolved in January 
2018. See Note 5 for additional information regarding the circumstances surrounding the VIE. The Company consolidates the 
financial statements of these entities. All material intercompany balances and transactions have been eliminated. 

Reclassifications. Certain  prior  period  amounts  have  been  reclassified  to  conform  to  the  2018  presentation.  These 

reclassifications had no impact on net income (loss), total assets, liabilities and stockholders’ equity or total cash flows. 

Use of estimates in the preparation of financial statements. Preparation of financial statements in conformity with GAAP 
requires  management  to  make  estimates  and  assumptions  that  affect  the  reported  amounts  of  assets  and  liabilities,  the 
disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and 
expenses during the reporting periods. Actual results could differ from these estimates. Depletion of oil and natural gas properties 
is  determined  using  estimates  of  proved  oil  and  natural  gas  reserves.  There  are  numerous  uncertainties  inherent  in  the 
estimation of quantities of proved reserves and in the projection of future rates of production and the timing of development 
expenditures.  Similarly,  evaluations  for  impairment  of  proved  and  unproved  oil  and  natural  gas  properties  are  subject  to 
numerous  uncertainties  including,  among  others,  estimates  of  future  recoverable  reserves,  commodity  price  outlooks  and 
prevailing market rates of other sources of income and costs. Other significant estimates include, but are not limited to, asset 
retirement  obligations,  goodwill,  fair  value  of  stock-based  compensation,  fair  value  of  business  combinations,  fair  value  of 
nonmonetary transactions, fair value of derivative financial instruments and income taxes. 

Cash equivalents. The Company considers all cash on hand, depository accounts held by banks, money market accounts 
and  investments  with  an  original  maturity  of  three  months  or  less  to  be  cash  equivalents.  The  Company’s  cash  and  cash 
equivalents are held in financial institutions in amounts that may exceed the insurance limits of the Federal Deposit Insurance 
Corporation. However, management believes that the Company’s counterparty risks are minimal based on the reputation and 
history of the institutions selected. 

Accounts receivable. The Company sells oil and natural gas to various customers and participates with other parties in 
the  drilling,  completion  and  operation  of  oil  and  natural  gas  wells.  Oil  and  natural  gas  sales  receivables  related  to  these 
operations  are  generally  unsecured.  Joint  interest  receivables  are  generally  secured  pursuant  to  the  operating  agreement 
between  or  among  the  co-owners  of  the  operated  property.  The  Company  determines  joint  interest  operations  accounts 
receivable  allowances  based  on  management’s  assessment  of  the  creditworthiness  of  the  joint  interest  owners  and  the 
Company’s  ability  to  realize  the  receivables  through  netting  of  anticipated  future  production  revenues.  Receivables  are 
considered  past due  if  full  payment is  not  received  by the contractual  due  date.  Past due  accounts are generally  written  off 
against  the  allowance  for  doubtful  accounts  only  after  all  collection  attempts  have  been  exhausted.  The  Company  had  an 
allowance for doubtful accounts of approximately $5 million and $1 million for the years ended December 31, 2018 and 2017, 
respectively. 

Inventory. Inventory consists primarily of tubular goods, water and other oilfield equipment that the Company plans to utilize 
in its ongoing exploration and development activities and is carried at the lower of weighted average cost or net realizable value. 

Oil and natural gas properties. The Company utilizes the successful efforts method of accounting for its oil and natural 
gas  properties.  Under  this  method  all  costs  associated  with  productive  wells  and  nonproductive  development  wells  are 
capitalized, while nonproductive exploration costs are expensed. Capitalized leasehold costs relating to proved properties are 
depleted using the unit-of-production method based on proved reserves. The depletion of capitalized drilling and development 
costs  and  integrated  assets  is  based  on  the  unit-of-production  method  using  proved  developed  reserves.  The  Company 
recognized depletion expense of $1.5 billion, $1.1 billion and $1.1 billion during the years ended December 31, 2018, 2017 and 
2016, respectively. 

The Company generally does not carry the costs of drilling an exploratory well as an asset in its consolidated balance 

sheets following the completion of drilling unless both of the following conditions are met: 

(i) 

the well has found a sufficient quantity of reserves to justify its completion as a producing well; and 

83 

 
 
  
 
 
 
 
 
 
 
 
 
Concho Resources Inc. 
Notes to Consolidated Financial Statements 
December 31, 2018, 2017 and 2016 

(ii) 

the Company is making sufficient progress assessing the reserves and the economic and operating viability 
of the project. 

Due to the Company’s large multi-well project development program, capital intensive nature and geographical location 
of  certain  projects,  it  may  take  longer  than  one  year  to  evaluate  the  future  potential  of  the  exploration  well  and  economics 
associated with making a determination on its commercial viability. In these instances, the project’s feasibility is not contingent 
upon  price  improvements  or advances  in  technology,  but  rather  the  Company’s  ongoing  efforts  and  expenditures  related  to 
accurately predicting the hydrocarbon recoverability based on well information, gaining access to other companies’ production, 
transportation  or  processing  facilities  and/or  getting  partner  approval  to  drill  additional  appraisal  wells.  The  Company’s 
assessment of suspended exploratory well costs is continuous until a decision can be made that the well has found proved 
reserves  and  is  transferred  to  proved  oil  and  natural  gas  properties  or  is  noncommercial  and  is  charged  to  exploration  and 
abandonments expense. See Note 3 for additional information regarding the Company’s exploratory well costs. 

Proceeds from the sales of individual properties and the capitalized costs of individual properties sold or abandoned are 
credited and charged, respectively, to accumulated depletion. Generally, no gain or loss is recognized until the entire depletion 
base is sold. However, gain or loss is recognized from the sale of less than an entire depletion base if the disposition is significant 
enough  to materially  impact  the  depletion  rate of  the  remaining  properties  in  the  depletion  base.  Ordinary  maintenance  and 
repair costs are expensed as incurred. 

Costs of significant nonproducing properties, wells in the process of being drilled and completed and development projects 
are  excluded  from  depletion  until  the  related  project  is  completed.  The  Company  capitalizes  interest  on  expenditures  for 
significant development projects until such projects are ready for their intended use. During the years ended December 31, 2018 
and 2017, the Company had capitalized interest of approximately $9 million and $3 million, respectively. The Company did not 
have capitalized interest related to significant oil and natural gas development projects for the year ended December 31, 2016. 

The Company reviews its long-lived assets to be held and used, including proved oil and natural gas properties, whenever 
events or circumstances indicate that the carrying value of those assets may not be recoverable. An impairment loss is indicated 
if the sum of the expected future cash flows is less than the carrying amount of the assets. In this circumstance, the Company 
recognizes an impairment loss for the amount by which the carrying amount of the asset exceeds the estimated fair value of the 
asset. The Company reviews its oil and natural gas properties by depletion base. For each property determined to be impaired, 
an impairment loss equal to the difference between the carrying value of the properties and the estimated fair value (discounted 
future cash flows) of the properties and integrated assets would be recognized at that time. Estimating future cash flows involves 
the use of judgments, including estimation of the proved and risk-adjusted unproved oil and natural gas reserve quantities, timing 
of development and production, expected future commodity prices, capital expenditures and production costs and cash flows 
from integrated assets. The Company did not recognize impairment expense during the years ended December 31, 2018 and 
2017. The Company recognized impairment expense of approximately $1.5 billion during the year ended December 31, 2016 
related to its proved oil and natural gas properties. See Note 8 for additional information regarding the Company’s impairment 
expense. 

Unproved  oil  and  natural  gas  properties  are  periodically  assessed  for  impairment  by  considering  future  drilling  and 
exploration plans, results of exploration activities, commodity price outlooks, planned future sales and expiration of all or a portion 
of the projects. During the years ended December 31, 2018, 2017 and 2016, the Company recognized expense of approximately 
$35 million, $27 million and $50 million, respectively, related to abandoned and expiring acreage, which is included in exploration 
and abandonments expense in the accompanying consolidated statements of operations. 

Other  property  and  equipment. Other  capital  assets  include  buildings,  transportation  equipment,  computer  equipment 
and software, telecommunications equipment, leasehold improvements and furniture and fixtures. These items are recorded at 
cost, or fair value if acquired, and are depreciated using the straight-line method based on expected lives of the individual assets 
or group of assets ranging from two to 39 years. The Company had other capital assets of $308 million and $234 million, net of 
accumulated depreciation of $109 million and $90 million, at December 31, 2018 and December 31, 2017, respectively. During 
the years ended December 31, 2018, 2017 and 2016, the Company recognized depreciation expense of $22 million, $21 million 
and $21 million, respectively.  

Goodwill. As a result of the RSP Acquisition, as defined in Note 4, the Company has goodwill in the amount of $2.2 billion 
at December 31, 2018. Goodwill is not amortized but assessed for impairment on an annual basis, or more frequently if indicators 
of  impairment  exist.  Impairment  tests,  which  involve  the  use  of  estimates  related  to  the  fair  market  value  of  the  business 
operations with which goodwill is associated, are performed as of July 1 of each year. The balance of goodwill is allocated in its 
entirety to the Company’s one reporting unit. When testing goodwill for impairment, the Company first performs a qualitative 
analysis to determine if it is more likely than not that the fair value of its reporting unit is less than its carrying value. If the analysis 
shows  that  the  fair  value  is  more  likely  than  not  less  than  the  carrying  value,  then  the  Company  performs  a  quantitative 
impairment test. The Company early adopted Accounting Standards Update (“ASU”) No. 2017-04, “Intangibles – Goodwill and 

84

Notes to Consolidated Financial Statements 
December 31, 2018, 2017 and 2016 

Other  (Topic  350):  Simplifying  the  Test  for  Goodwill  Impairment”  (“ASU  2017-04”).  Per  ASU  2017-04,  if  the  results  of  the 
quantitative test are such that the fair value of the reporting unit is less than the carrying value, goodwill is reduced by an amount 
that is equal to the amount by which the carrying value of the reporting unit exceeds the fair value. Because of the recent decline 
in the price of oil and the volatility of the Company’s common stock, the Company performed an analysis at December 31, 2018 
and determined that it was not more likely than not that the fair value of its reporting unit was less than its carrying value. As a 
result, the Company did not recognize impairment expense during the year ended December 31, 2018.  

Equity  method  investments.  The  Company  accounts  for  its  equity  method  investments  under  the  equity  method  of 
accounting and includes the investment balance in other assets on the consolidated balance sheets. Gains and losses incurred 
from the Company’s equity investments are recorded in other income (expense) on the consolidated statements of operations. 

 At December 31, 2018, the Company owned a 23.75 percent membership interest in Oryx Southern Delaware Holdings, 
LLC (“Oryx”), an entity that operates a crude oil gathering and transportation system in the Delaware Basin. In February 2018, 
Oryx obtained a term loan of $800 million. The proceeds were used in part to fund a cash distribution to its equity holders, of 
which the Company received a distribution of approximately $157 million. Of this amount, approximately $54 million fully offset 
the Company’s net investment in Oryx. The remaining distribution of approximately $103 million was recorded in other income 
(expense)  on  the  Company’s consolidated statement of  operations  since  the  lenders to the  term loan  do  not  have  recourse 
against the Company, and the Company has no contractual obligation to repay the distribution.  

The  Company’s  net  investment  in  Oryx  was  zero  and  approximately  $49  million  at  December  31,  2018  and  2017, 
respectively. The Company recorded income of approximately $4 million and $7 million for the years ended December 31, 2018 
and 2017, respectively. The Company will not record income or loss on the Oryx investment until such net income is greater 
than the distribution in excess of its investment.  

On  December  26,  2018,  the  Company  contributed  certain  infrastructure  assets  to  WaterBridge  Operating  LLC 
(“WaterBridge”),  an  entity  that  operates  and  manages  various  water  infrastructure  assets  located  in  the  Permian  Basin,  in 
exchange for, among other consideration, 100,000 Series A-1 Preferred Units (“Preferred Units”). The Preferred Units contain 
certain redemption rights, incentives and restrictions, as specified in the agreement. The Company accounts for the investment 
using the equity method. In conjunction with the transaction, the Company entered into a water management services agreement 
with WaterBridge. The Company had no amounts due to WaterBridge at December 31, 2018. The Company’s investment in 
WaterBridge is recorded in other assets in the Company’s consolidated balance sheets.   

In February 2017, the Company closed on the divestiture of its 50 percent membership interest in a midstream joint venture, 
Alpha Crude Connector, LLC (“ACC”), that constructed a crude oil gathering and transportation system in the Delaware Basin. 
See Note 5 for additional information regarding the disposition of ACC.  

Regulatory and environmental compliance. The Company is subject to extensive federal, state and local environmental 
laws and regulations. These laws, which are often changing, regulate the discharge of materials into the environment and may 
require  the  Company  to  remove  or  mitigate  the  environmental  effects  of  the  disposal  or  release  of  petroleum  or  chemical 
substances at various sites. Regulatory liabilities relate to acquisitions where additional equipment is necessary to have facilities 
compliant  with  local, state  and  federal  obligations and  are capitalized.  Environmental expenditures  that  relate  to an  existing 
condition caused by past operations and that have no future economic benefits are expensed. Liabilities for expenditures that 
are noncapital in nature are recorded when environmental assessment and/or remediation is probable and the costs can be 
reasonably  estimated.  Such  liabilities  are  generally  undiscounted  unless  the  timing  of  cash  payments  is  fixed  and  readily 
determinable. Environmental liabilities normally involve estimates that are subject to revisions until settlement occurs. See Note 
11 for additional information. 

Litigation contingencies. The Company is a party to proceedings and claims incidental to its business. In each reporting 
period, the Company assesses these claims in an effort to determine the degree of probability and range of possible loss for 
potential accrual in its consolidated financial statements. The amount of any resulting losses may differ from these estimates. 
An accrual is recorded for a material loss contingency when its occurrence is probable and damages are reasonably estimable. 
See Note 11 for additional information. 

Income taxes. The Company recognizes deferred tax assets and liabilities for the future tax consequences attributable to 
differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. 
Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in 
which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a 
change in tax rate is recognized in income in the period that includes the enactment date. A valuation allowance is established 
to reduce deferred tax assets if it is more likely than not that the related tax benefits will not be realized.

The  Company  evaluates  uncertain  tax  positions  for  recognition  and  measurement  in  the  consolidated  financial 
statements. To recognize a tax position, the Company determines whether it is more likely than not that the tax position will be 
sustained upon examination, including resolution of any related appeals or litigation, based on the technical merits of the position. 
A tax position that meets the more likely than not threshold is measured to determine the amount of benefit to be recognized in 
the consolidated financial statements. The amount of tax benefit recognized with respect to any tax position is measured as the 
largest amount of benefit that is greater than 50 percent likely of being realized upon settlement. At December 31, 2018, the 
Company had unrecognized tax benefits of approximately $63 million, primarily related to research and development credits. If 
all or a portion of the unrecognized tax benefit is sustained upon examination by the taxing authorities, the tax benefit will be 
recognized as a reduction to the Company’s deferred tax liability and will affect the Company’s effective tax rate in the period 
recognized. The timing as to when the Company will substantially resolve the uncertainties associated with the unrecognized 
tax benefit is uncertain. The Company has not recognized any interest or penalties relating to unrecognized tax benefits in its 
consolidated financial statements. Any interest or penalties would be recognized as a component of income tax expense. 

On December 22, 2017, the President of the United States (the “President”) signed into law the tax bill commonly referred 
to as the “Tax Cuts and Job Act” (“TCJA”), significantly changing federal income tax laws. According to the Accounting Standards 
Codification (“ASC”) section 740, “Income Taxes,” (“ASC 740”), a company is required to record the effects of an enacted tax 
law or rate change in the period of enactment, which is the date the bill is signed by the President and becomes law. As a result 
of the enactment of the TCJA, the U.S. Securities and Exchange Commission (“SEC”) issued Staff Accounting Bulletin (“SAB”) 
No. 118, “Income Tax Accounting Implications of the Tax Cuts and Jobs Act,” (“SAB 118”) to provide guidance for companies 
that have not completed the accounting for the income tax effects of the TCJA in the period of enactment. SAB 118 allowed 
companies  to  report  provisional  amounts  when  based  on  reasonable  estimates  and  to  adjust  these  amounts  during  a 
measurement period of up to one year. The Company elected to apply SAB 118 and, as such, recorded provisional amounts for 
the income tax balances reported in its consolidated financial statements at December 31, 2017. At December 31, 2018, the 
Company completed its accounting for all tax effects of the TCJA and made an adjustment to its provisional amounts related to 
the deductibility of certain compensation based on available regulatory and interpretive guidance. See Note 12 for additional 
information regarding the Company’s deferred tax balances and the impacts of the TCJA. 

Derivative instruments. The Company recognizes its derivative instruments, other than commodity derivative contracts 
that are designated as normal purchase and normal sale contracts, as either assets or liabilities measured at fair value. The 
Company nets the fair value of the derivative instruments by counterparty in the accompanying consolidated balance sheets 
when the right of offset exists. The Company does not have any derivatives designated as fair value or cash flow hedges. The 
Company may also enter into physical delivery contracts to effectively provide commodity price hedges. Because these contracts 
are not expected to be net cash settled, they are considered to be normal sales contracts and not derivatives. Therefore, these 
contracts are not recorded in the Company’s consolidated balance sheets. 

Asset retirement obligations. The Company records the fair value of a liability for an asset retirement obligation in the 
period in which it is incurred and a corresponding increase in the carrying amount of the related oil and natural gas property 
asset.  Subsequently,  the  asset  retirement  cost  included  in  the  carrying  amount  of  the  related  asset  is  allocated  to  expense 
through depletion of the asset. Changes in the liability due to passage of time are recognized as an increase in the carrying 
amount of the liability through accretion expense. Based on certain factors, including commodity prices and costs, the Company 
may revise its previous estimates of the liability, which would also increase or decrease the related oil and natural gas property 
asset. 

Treasury stock. Treasury stock purchases are recorded at cost. 

Revenue  recognition.  On  January  1,  2018,  the  Company  adopted  ASC  Topic  606,  “Revenue  from  Contracts  with 
Customers,” (“ASC 606”) using the modified retrospective approach, which only applies to contracts that were not completed as 
of the date of initial application. The adoption did not require an adjustment to opening retained earnings for the cumulative effect 
adjustment and does not have a material impact on the Company’s reported net income (loss), cash flows from operations or 
statement of stockholders’ equity.  

The Company recognizes revenues from the sales of oil and natural gas to its customers and presents them disaggregated 
on the Company’s consolidated statements of operations. All revenues are recognized in the geographical region of the Permian 
Basin. Prior to the adoption of ASC 606, the Company recorded oil and natural gas revenues at the time of physical transfer of 
such products to the purchaser, which for the Company is primarily at the wellhead. The Company followed the sales method of 
accounting for oil and natural gas sales, recognizing revenues based on the Company’s actual proceeds from the oil and natural 
gas sold to purchasers. 

The Company enters into contracts with customers to sell its oil and natural gas production. Revenue on these contracts is 
recognized  in  accordance  with  the  five-step  revenue  recognition  model  prescribed  in  ASC  606.  Specifically,  revenue  is 
recognized when the Company’s performance obligations under these contracts are satisfied, which generally occurs with the 

86

December 31, 2018, 2017 and 2016 

transfer of control of the oil and natural gas to the purchaser. Control is generally considered transferred when the following 
criteria are met: (i) transfer of physical custody, (ii) transfer of title, (iii) transfer of risk of loss and (iv) relinquishment of any 
repurchase rights or other similar rights. Given the nature of the products sold, revenue is recognized at a point in time based 
on  the  amount  of  consideration  the  Company  expects  to  receive  in  accordance  with  the  price  specified  in  the  contract. 
Consideration under the oil and natural gas marketing contracts is typically received from the purchaser one to two months after 
production. At December 31, 2018, the Company had receivables related to contracts with customers of approximately $466 
million. 

The following table shows the impact of the adoption of ASC 606 on the Company’s current period results as compared to 

the previous revenue recognition standard, ASC Topic 605, “Revenue recognition” (“ASC 605”):

Oil  Contracts.  The  majority  of  the  Company’s  oil  marketing  contracts  transfer  physical  custody  and  title  at  or  near  the 
wellhead, which is generally when control of the oil has been transferred to the purchaser. The majority of the oil produced is 
sold under contracts using market-based pricing which is then adjusted for differentials based upon delivery location and oil 
quality. To the extent the differentials are incurred after the transfer of control of the oil, the differentials are included in oil sales 
on the statements of operations as they represent part of the transaction price of the contract. If the differentials, or other related 
costs, are incurred prior to the transfer of control of the oil, those costs are included in gathering, processing and transportation 
on  the  Company’s  consolidated  statements  of  operations  as  they  represent  payment  for  services  performed  outside  of  the 
contract with the customer.  

Natural Gas Contracts. The majority of the Company’s natural gas is sold at the lease location, which is generally when 
control  of  the  natural  gas  has  been  transferred  to  the  purchaser.  The  natural  gas  is  sold  under  (i)  percentage  of  proceeds 
processing contracts, (ii) fee-based contracts or (iii) a hybrid of percentage of proceeds and fee-based contracts. Under the 
majority of the Company’s contracts, the purchaser gathers the natural gas in the field where it is produced and transports it via 
pipeline to natural gas processing plants where natural gas liquid products are extracted. The natural gas liquid products and 
remaining residue gas are then sold by the purchaser. Under the percentage of proceeds and hybrid percentage of proceeds 
and fee-based contracts, the Company receives a percentage of the value for the extracted liquids and the residue gas. Under 
the fee-based contracts, the Company receives natural gas liquids and residue gas value, less the fee component, or is invoiced 
the fee component. To the extent control of the natural gas transfers upstream of the transportation and processing activities, 
revenue is recognized as the net amount received from the purchaser. To the extent that control transfers downstream of those 
costs, revenue is recognized on a gross basis, and the related costs are classified in gathering, processing and transportation 
on the Company’s consolidated statements of operations. 

The Company does not disclose the value of unsatisfied performance obligations under its contracts with customers as it 
applies the practical exemption in accordance with ASC 606. The exemption, as described in ASC 606-10-50-14(a), applies to 
variable consideration that is recognized as control of the product is transferred to the customer. Since each unit of product 
represents  a  separate  performance  obligation,  future  volumes  are  wholly  unsatisfied  and  disclosure  of  the  transaction  price 
allocated to remaining performance obligations is not required. 

General and administrative expense. The Company receives fees for the operation of jointly-owned oil and natural gas 
properties  during  the  drilling  and  production  phases  and  records  such  reimbursements  as  reductions  of  general  and 
administrative expense. Such fees totaled approximately $19 million, $16 million and $17 million for the years ended December 
31, 2018, 2017 and 2016, respectively.

Stock-based compensation. Stock-based compensation expense is recognized in the Company’s financial statements on 
an accelerated basis over the awards’ vesting periods based on their grant date fair values. Stock-based compensation awards 
vest over a period generally ranging from one to five years. The Company utilizes the average of the high and low stock prices 
at each grant date to determine the fair value of restricted stock and the Monte Carlo simulation method to determine the fair 
value of performance unit awards. The Company recognizes forfeitures on stock-based compensation awards as they occur. 
When the Company adopted ASU No. 2016-09, “Compensation–Stock Compensation (Topic 718): Improvements to Employee 
Share-based  Payment  Accounting,”  (“ASU  2016-09”)  on  January  1, 2017,  it  recorded  a cumulative effect  adjustment, which 
decreased  retained  earnings  by  less  than  $1  million,  increased  additional  paid-in  capital  by  approximately  $8  million  and 
decreased net deferred income tax liabilities by approximately $8 million.  

Recently adopted accounting pronouncements. In January 2017, the Financial Accounting Standards Board (“FASB”) 
issued ASU No. 2017-04, which simplifies how an entity subsequently measures goodwill by eliminating Step 2 from the goodwill 
impairment test. In place of Step 2, an entity will recognize an impairment charge for the amount by which the carrying amount 
of a reporting unit exceeds its fair value; however, the loss recognized should not exceed the total amount of goodwill allocated 
to  the  reporting  unit.  The  Company  early  adopted  this  standard  beginning  in  the  third  quarter  of  2018.  The  adoption of  this 
standard did not have an impact on the Company’s financial results. 

In January 2017, the FASB issued ASU No. 2017-01, “Business Combinations (Topic 805): Clarifying the Definition of a 
Business,” with the objective of adding guidance to assist in evaluating whether transactions should be accounted for as asset 
acquisitions or as business combinations. The guidance provides a screen to determine when an integrated set of assets and 
activities is not a business. The screen requires that when substantially all of the fair value of the acquired assets is concentrated 
in a single asset or a group of similar assets, the set is not a business. If the screen is not met, to be considered a business, the 
set  must  include  an  input  and  a  substantive  process  that  together  significantly  contribute to  the ability  to create output.  The 
Company adopted this standard on January 1, 2018. See Notes 4 and 5 for information regarding the Company’s significant 
acquisitions and divestitures. 

New accounting pronouncements issued but not yet adopted. In February 2016, the FASB issued ASU No. 2016-02, 
“Leases (Topic 842)” (“ASU 2016-02”), which supersedes current lease guidance. The new lease standard requires all leases 
with a term greater than one year to be recognized on the balance sheet while maintaining substantially similar classifications 
for financing and operating leases. Lease expense recognition on the consolidated statements of operations will be effectively 
unchanged.  This guidance is effective  for  reporting  periods beginning  after  December  15,  2018.  The  Company made  policy 
elections  to  not  capitalize  short-term  leases  for  all  asset  classes  and  to  not  separate  non-lease  components  from  lease 
components for all asset classes except for vehicles. The Company also plans to not elect the package of practical expedients 
that allows for certain considerations under the original “Leases (Topic 840)” accounting standard (“Topic 840”) to be carried 
forward upon adoption of ASU 2016-02.  

The Company enters into lease agreements to support its operations. These agreements are for leases on assets such as 
office space, vehicles, well equipment and drilling rigs. The Company has completed the process of reviewing and determining 
the contracts to which this new guidance applies. Upon adoption, on January 1, 2019, the Company recognized approximately 
$35 million of right-of-use assets, of which approximately $19 million and $16 million relate to the Company’s operating and 
financing  leases,  respectively,  and  approximately  $37  million  of  associated  lease  liabilities  that  are  not  currently  recognized 
under applicable guidance.  

In January 2018, the FASB issued ASU No. 2018-01, “Land Easement Practical Expedient for Transition to Topic 842,” 
which provides an optional practical expedient to not evaluate land easements that existed or expired before the adoption of 
ASU 2016-02 and that were not previously accounted for as leases under Topic 840. The Company enters into land easements 
on a routine basis as part of its ongoing operations and has many such agreements currently in place; however, the Company 
does not currently account for any land easements under Topic 840. As this guidance serves as an amendment to ASU 2016-
02, the Company will elect this practical expedient, which becomes effective upon the date of adoption of ASU 2016-02. After 
the adoption of ASU 2016-02, the Company will assess any new land easements to determine whether the arrangement should 
be accounted for as a lease. In July 2018, the FASB issued ASU No. 2018-11, “Targeted Improvements,” which provides a 
transition election to not restate comparative periods for the effects of applying the new lease standard. This transition election 
permits entities to change the date of initial application to the beginning of the year of adoption and to recognize the effects of 
applying the new standard as a cumulative-effect adjustment to the opening balance of retained earnings. The Company elected 
this transition approach, however the cumulative impact of adoption in the opening balance of retained earnings as of January 
1, 2019 was zero. 

In  June  2016,  the  FASB  issued  ASU  No.  2016-13,  “Financial  Instruments–Credit  Losses  (Topic  326):  Measurement  of 
Credit Losses on Financial Instruments,” (“Topic 326”) which replaces the current “incurred loss” methodology for recognizing 
credit losses with an “expected loss” methodology. This new methodology requires that a financial asset measured at amortized

cost be presented at the net amount expected to be collected. This standard is intended to provide more timely decision-useful 
information about the expected credit losses on financial instruments. In November 2018, the FASB issued ASU No. 2018-19, 
“Codification Improvements to Topic 326, Financial Instruments-Credit Losses,” which makes amendments to clarify the scope 
of the guidance, including the amendment clarifying that receivables arising from operating leases are not within the scope of 
Topic 326. This guidance is effective for fiscal years beginning after December 15, 2019, and early adoption is allowed as early 
as fiscal years beginning after December 15, 2018. The Company does not believe this new guidance will have a material impact 
on its consolidated financial statements. 

In July 2018, the FASB issued ASU No. 2018-09, “Codification Improvements,” (“ASU 2018-09”) which makes amendments 
to multiple codification topics to clarify, correct errors in, or make minor improvements to the accounting standards codification. 
The effective date of the standard is dependent on the facts and circumstances of each amendment. Some amendments do not 
require transition guidance and will be effective upon the issuance of this standard. Many of the amendments in ASU 2018-09 
will be effective in annual periods beginning after December 15, 2018. The Company will be required to adopt this standard in 
the first quarter of fiscal 2019. The Company is currently assessing the effect that this ASU will have on the financial position, 
results of operations, and disclosures. 

On  August  17,  2018,  the  SEC  issued  a  final  rule  that  amends  certain  of  its  disclosure  requirements  that  have  become 
redundant, duplicative, overlapping, outdated or superseded, in light of other disclosure requirements, U.S. GAAP or changes 
in the information environment. The amendments are intended to facilitate the disclosure of information to investors and simplify 
compliance without significantly altering the total mix of information provided to investors. The final rule amends numerous SEC 
rules, items and forms covering a diverse group of topics, including, but not limited to, changes in stockholders’ equity. The final 
rule extends to interim periods the annual disclosure requirement in SEC Regulation S-X, Rule 3-04, of presenting changes in 
stockholders’ equity. The registrants will be required to analyze changes in stockholders’ equity in the form of a reconciliation 
for the current quarter and year-to-date interim periods and comparative periods in the prior year. The final rule became effective 
for all filings submitted on or after November 5, 2018. 

In November 2018, the FASB issued ASU No. 2018-18, “Collaborative Arrangements (Topic 808): Clarifying the Interaction 
between Topic 808 and Topic 606,” (“ASU 2018-18”) which, among other things, clarifies that (i) certain transactions between 
collaborative arrangement participants should be accounted for as revenue under Topic 606 when the collaborative arrangement 
participant is a customer in the context of a unit of account, (ii) adds unit-of-account guidance in Topic 808 to align with the 
guidance  in  Topic  606 and  (iii)  requires  that  in a  transaction  with  a  collaborative  arrangement  participant  that  is  not directly 
related to sales to third parties, presenting the transaction together with revenue recognized under Topic 606 is precluded if the 
collaborative arrangement participant is not a customer. ASU 2018-18 is effective for fiscal years beginning after December 15, 
2019, and interim periods within those fiscal years and early adoption is permitted. The amendments in this update should be 
applied retrospectively to the date of initial application of Topic 606. An entity should recognize the cumulative effect of initially 
applying the amendments as an adjustment to the opening balance of retained earnings of the later of the earliest annual period 
presented and the annual period that includes the date of the entity’s initial application of Topic 606. The Company is currently 
assessing the effect that ASU 2018-18 will have on its financial position, results of operations and disclosures.

Note 3. Exploratory well costs 

The Company capitalizes exploratory well costs until a determination is made that the well has either found proved reserves 
or that it is impaired. The capitalized exploratory well costs are carried in unproved oil and natural gas properties. See Unaudited 
Supplementary  Data  for  the  proved  and  unproved  components  of  oil  and  natural  gas  properties.  If  the  exploratory  well  is 
determined to be impaired, the well costs are charged to exploration and abandonments expense in the consolidated statements 
of operations.

Note 4. RSP Acquisition 

On July 19, 2018, the Company completed the acquisition of RSP Permian, Inc. (“RSP”) through an all-stock transaction 
(the  “RSP  Acquisition”).  RSP  was  an  independent  oil  and  natural  gas  company  engaged  in  the  acquisition,  exploration, 
development and production of unconventional oil and associated liquids-rich natural gas reserves in the Permian Basin of West 
Texas. The vast majority of RSP’s acreage was located on large, contiguous acreage blocks in the core of the Midland Basin 
and the Delaware Basin. The acquisition added approximately 92,000 net acres. Under the terms of the Agreement and Plan of 
Merger (the “Acquisition Agreement”), each share of RSP common stock was converted into 0.320 of a share of the Company’s 
common stock. The Company issued approximately 51 million shares of common stock at a price of $148.27 per share, resulting 
in total consideration paid by the Company to the former RSP shareholders of approximately $7.5 billion.  

In connection with the closing of the RSP Acquisition, the Company repaid outstanding principal under RSP’s revolving 
credit  facility  and  redeemed  and  canceled  all  of  RSP’s  outstanding  unsecured  senior  notes.  See  Note  10  for  additional 
information regarding the Company’s debt activity. 

In  connection  with  the  RSP  Acquisition,  the  Company  incurred  approximately  $32 million  of  costs  related  to  consulting, 
investment banking, advisory, legal and other acquisition-related fees during the year ended December 31, 2018, which are 
included in transaction costs in operating costs and expenses on the consolidated statements of operations. In addition, the 
Company acquired 670,369 shares of common stock from RSP employees for the payment of withholding taxes due on the 
vesting of their restricted shares pursuant to the Acquisition Agreement, resulting in an increase of approximately $32 million in 
the Company’s treasury stock balance. 

Purchase price allocation. The RSP Acquisition has been accounted for as a business combination, using the acquisition 
method. The following table represents the preliminary allocation of the total purchase price of RSP to the identifiable assets 
acquired and the liabilities assumed based on the fair values at the acquisition date, with any excess of the purchase price over 
the  estimated  fair  value  of  the  identifiable  net  assets  acquired  recorded  as  goodwill.  Any  value  assigned  to  goodwill  is  not 
expected to be deductible for income tax purposes. Certain data necessary to complete the purchase price allocation is not yet 
available, including tax return data from RSP’s short period ending July 19, 2018 that provides underlying tax basis in assets 
and liabilities and uncertain tax positions.

The fair values of assets acquired and liabilities assumed were based on the following key inputs: 

Oil and natural gas properties 

The fair value of proved and unproved oil and natural gas properties was measured using valuation techniques that convert 
the future cash flows to a single discounted amount. Significant inputs to the valuation of proved and unproved oil and natural 
gas properties include estimates of: (i) recoverable reserves; (ii) production rates; (iii) future operating and development costs; 
(iv) future commodity prices; and (v) a market-based weighted average costs of capital. The Company utilized a combination of 
the NYMEX strip pricing and consensus pricing, adjusted for differentials, to value the reserves. The Company’s estimates of 
commodity  prices  for  purposes  of  determining  discounted  cash  flows  ranged  from  a  2018  price  of  $66.59  per  barrel  of  oil 
decreasing to a 2022 price of $63.41 per barrel of oil. Similarly, natural gas prices ranged from a 2018 price of $2.80 per MMBtu 
then rising to a 2022 price of $3.09 per MMBtu. Both oil and natural gas commodity prices were held flat after 2022 and adjusted 
for  inflation.  The  Company  then  applied  various  discount  rates  depending  on  the  classification  of  reserves  and  other  risk 
characteristics. Management utilized the assistance of a third-party valuation expert to estimate the value of the oil and natural 
gas properties acquired.  

The fair value of asset retirement obligations totaled $20 million and is included in proved oil and natural gas properties with 
a  corresponding  liability  in  the  table  above.  The  fair  value  was  determined  based  on  a  discounted  cash  flow  model,  which 
included assumptions of the estimated current abandonment costs, discount rate, inflation rate and timing associated with the 
incurrence of these costs.  

The inputs used to value oil and natural gas properties and asset retirement obligations require significant judgment and 

estimates made by management and represent Level 3 inputs.

Financial instruments and other 

The fair value measurements of long-term debt were estimated based on the market prices and represent Level 1 inputs. 
The fair value measurements of derivative instruments assumed were determined based on published forward commodity price 
curves, implied market volatility, contract terms and prices and discount factors as of the close date of the RSP Acquisition and 
represent  Level  2  inputs.  The  fair  values  of  commodity  derivative  instruments  in  an  asset  position  include  a  measure  of 
counterparty nonperformance risk and the derivative instruments in a liability position include a measure of the Company’s own 
nonperformance risk, each based on the current published credit default swap rates. 

The  fair  values  determined  for  accounts  receivable,  accounts  payable  –  trade,  accrued  drilling  costs  and  other  current 

liabilities were equivalent to the carrying value due to their short-term nature. 

Other current liabilities include approximately $16 million of liabilities primarily related to certain regulatory obligations. 

Deferred income taxes  

The RSP Acquisition qualified as a tax-free merger whereby the Company acquired carryover tax basis in RSP’s assets 
and liabilities, adjusted for differences between the purchase price allocated to the assets acquired and liabilities assumed based 
on the fair value and the carryover tax basis. See Note 12 for additional discussion of deferred income taxes. 

Goodwill recognized is primarily attributable to the following factors: (i) operating and administrative synergies and (ii) net 
deferred tax liabilities arising from the differences between the purchase price allocated to RSP’s assets and liabilities based on 
fair value and the tax basis of these assets and liabilities. For the operating and administrative synergies, the total consideration 
for the RSP Acquisition included a control premium, which resulted in a higher value compared to the fair value of net assets 
acquired. There are also other qualitative assumptions of long-term factors that the RSP Acquisition creates for the Company’s 
stockholders, including additional potential for exploration and development opportunities and additional scale and efficiencies 
in basins in which the Company operates. 

Approximately $506 million of operating revenues and approximately $274 million of income from operations attributed to 
the  RSP  Acquisition  are  included  in  the  Company’s  results  of  operations  from  the  closing  date  on  July  19,  2018  through 
December 31, 2018.

Pro forma data. The following unaudited pro forma combined condensed financial data for the years ended December 31, 
2018 and 2017 was derived from the historical financial statements of the Company giving effect to the RSP Acquisition, as if it 
had occurred on  January 1, 2017.  The  below  information  reflects  pro  forma  adjustments  for  the issuance  of  the  Company’s 
common stock in exchange for RSP’s outstanding shares of common stock, as well as pro forma adjustments based on available 
information and  certain assumptions  that  the  Company  believes  are  reasonable, including  (i)  the  Company’s  common  stock 
issued to convert RSP’s outstanding shares of common stock and equity awards as of the closing date of the RSP Acquisition, 
(ii)  the  depletion  of  RSP’s  fair-valued  proved  oil  and  gas  properties  and  (iii)  the  estimated  tax  impacts  of  the  pro  forma 
adjustments. 

Additionally,  pro  forma  earnings  were  adjusted  to  exclude  acquisition-related  costs  incurred  by  the  Company  of 
approximately $32 million for the year ended December 31, 2018 and acquisition-related costs incurred by RSP and severance 
payments to certain RSP employees that totaled approximately $56 million for the year ended December 31, 2018. The pro 
forma results of operations do not include any cost savings or other synergies that may result from the RSP Acquisition. The pro 
forma financial data does not include the pro forma results of operations for any other acquisitions made during the period. The 
pro forma combined condensed financial data has been included for comparative purposes only and is not necessarily indicative 
of the results that might have occurred had the RSP Acquisition taken place on January 1, 2017 and is not intended to be a 
projection of future results.

Note 5. Acquisitions, divestitures and nonmonetary transactions 

During the year ended December 31, 2018, the Company closed on the following transactions (exclusive of the RSP Acquisition 
disclosed in Note 4): 

February 2018 acquisition and divestiture. In February 2018, the Company closed on an acquisition treated as a business 
combination  where  it  received  producing  wells  with  approximately  5  MBoepd  along  with  approximately  21,000  net  acres, 
primarily  located  in  the  Midland  Basin.  As  consideration  for  the  non-cash  acquisition,  the  Company  divested  approximately 
34,000 net acres, primarily comprised of approximately 32,000 net acres in the northern Delaware Basin, with production of 3 
MBoepd.  The  business  acquired  was  valued  at  approximately  $755  million  as  compared  to  the  historical  book  value  of  the 
divested assets of approximately $180 million, which resulted in a non-cash gain of approximately $575 million. The fair value 
of  the  assets  acquired  totaled  approximately  $755  million,  which  was  comprised  of  approximately  $245  million  of  proved 
properties, approximately $480 million of unproved properties and approximately $30 million of other assets. The fair value of 
the assets received in the business combination approximated the fair value of assets disposed. 

Delaware Basin divestitures. In January 2018, the Company closed on two asset sales transactions of certain non-core 
assets in Reeves and Ward Counties, Texas, with combined proceeds of approximately $280 million. After direct transaction 
costs, the Company recorded a pre-tax gain of approximately $134 million, which is included in gain on disposition of assets, 
net on its consolidated statement of operations for the year ended December 31, 2018. The assets divested included proved 
and unproved oil and natural gas properties on approximately 20,000 net acres.  

These  divestitures  completed  a  transaction  structured  as  a  reverse  like-kind  exchange  (“Reverse  1031  Exchange”)  in 
accordance with Section 1031 of the Internal Revenue Code of 1986, as amended, that the Company entered into concurrent 
with its July 2017 Midland Basin acquisition, as further described below.  

Upon completion of the Reverse 1031 Exchange in January 2018, the assets and liabilities attributable to the acquisition 

that were held by the VIE were conveyed to the Company, and the VIE structure was dissolved. 

Nonmonetary transactions. During 2018, the Company completed multiple nonmonetary transactions. These transactions 
included exchanges of both proved and unproved oil and natural gas properties. Certain of these transactions were accounted 
for at fair value and, as a result, the Company recorded pre-tax gains of approximately $15 million. 

During the year ended December 31, 2017, the Company closed on the following transactions: 

Delaware Basin acquisition. In January and April 2017, the Company closed on the two-part acquisition in the northern 
Delaware Basin. As consideration for the entire acquisition, the Company paid approximately $160 million in cash, of which $43 
million was held in escrow at December 31, 2016, and issued to the seller approximately 2.2 million shares of its common stock 
with an approximate value of $291 million. 

ACC divestiture. In February 2017, the Company closed on the divestiture of its ownership interest in ACC. The Company 
and its joint venture partner entered into separate agreements to sell 100 percent of their respective ownership interests in ACC. 
After  adjustments  for  debt  and  working  capital,  the  Company  received  cash  proceeds  from  the  sale  of  approximately  $801 
million. After direct transaction costs, the Company recorded a pre-tax gain on disposition of assets of approximately $655 million 
which is included in gain on disposition of assets, net on its consolidated statement of operations for the year ended December 
31, 2017. The Company’s net investment in ACC at the time of closing was approximately $129 million. 

Midland Basin acquisition. In July 2017, the Company completed an acquisition in the Midland Basin. As consideration 

for the acquisition, the Company paid approximately $595 million in cash. 

Concurrent  with  the  acquisition,  the  Company  entered  into  a  transaction  structured  as  a  Reverse  1031  Exchange.  In 
connection with the Reverse 1031 Exchange, the Company assigned the ownership of the oil and natural gas properties acquired 
to a VIE formed by an exchange accommodation titleholder. The Company operates the properties pursuant to a management 
agreement with the VIE. At December 31, 2017, the Company was determined to be the primary beneficiary of the VIE, as the 
Company had the ability to control the activities that most significantly impact the VIE’s economic performance. The assets held 
by the VIE attributable to the acquisition were conveyed to the Company and the VIE structure terminated upon the completion 
of  the  Reverse  1031  Exchange.  At  December  31,  2017,  the  VIE’s  total  assets  and  liabilities  included  in  the  Company’s 
consolidated balance sheet were approximately $608 million and $604 million, respectively.  

Nonmonetary transactions. During 2017, the Company completed multiple nonmonetary transactions. The transactions 
included exchanges of both proved and unproved oil and natural gas properties. Certain of these transactions were accounted 
for at fair value and as a result the Company recorded pre-tax gains totaling approximately $26 million.

During the year ended December 31, 2016, the Company closed on the following transactions: 

Asset  divestiture. In  February  2016,  the  Company sold certain  assets in  the northern  Delaware  Basin  for proceeds of 

approximately $292 million and recognized a pre-tax gain of approximately $110 million. 

Delaware Basin acquisition. In March 2016, the Company completed an acquisition of 80 percent of a third-party seller’s 
interest in certain oil and natural gas properties and related assets in the southern Delaware Basin. As consideration for the 
acquisition, the Company issued to the seller approximately 2.2 million shares of common stock with an approximate value of 
$231 million, $146 million in cash and $40 million to carry a portion of the seller’s future development costs in these properties 
that was expended in 2016 and 2017 and included in costs incurred.  

Reliance acquisition. In October 2016, the Company completed an acquisition of approximately 40,000 net acres in the  
Midland Basin and other assets from Reliance Energy, Inc. (collectively, the “Reliance Acquisition”) for approximately $1.7 billion. 
As consideration for the acquisition, the Company paid approximately $1.2 billion in cash and issued to the seller approximately 
3.9 million shares of common stock with an approximate value of $0.5 billion. 

Approximately $29 million of operating revenues and approximately $10 million of income from operations attributed to the 
Reliance Acquisition are included in the Company’s results of operations from the closing date in October 2016 through the year 
ended December 31, 2016. 

Pro forma data. The following unaudited pro forma combined condensed financial data for the year ended December 31, 
2016 was derived from the historical financial statements of the Company giving effect to the Reliance Acquisition, as if it had 
occurred on January 1, 2016. The results of operations for the Reliance Acquisition are included in the Company’s results of 
operations since the closing date in October 2016 through December 31, 2018. The pro forma financial data does not include 
the  pro  forma  results  of  operations  for  any  other  acquisitions  made  during  the  period.  The  pro  forma  combined  condensed 
financial data has been included for comparative purposes only and is not necessarily indicative of the results that might have 
occurred had the Reliance Acquisition taken place on January 1, 2016 and is not intended to be a projection of future results.

Note 6. Asset retirement obligations 

The  Company’s  asset  retirement  obligations  represent  the  estimated  present  value  of  the  estimated  cash  flows  the 
Company will incur to plug, abandon and remediate its producing properties at the end of their productive lives, in accordance 
with  applicable  state  laws.  Market  risk  premiums  associated  with  asset  retirement  obligations  are  estimated  to  represent  a 
component of the Company’s credit-adjusted risk-free rate that is utilized in the calculations of asset retirement obligations. 

The Company’s asset retirement obligation transactions during the years ended December 31, 2018, 2017 and 2016 are

Note 7. Incentive plans 

Defined contribution plan. The Company sponsors a 401(k) defined contribution plan for the benefit of its employees. 
During the years ended December 31, 2018, 2017 and 2016, the Company matched 100 percent of employee contributions, not 
to exceed 10 percent of the employee’s annual eligible compensation, subject to federal limits. The Company’s contributions to 
the plan for the years ended December 31, 2018, 2017 and 2016 were approximately $12 million, $10 million and $9 million, 
respectively. 

Stock incentive plan. The Company’s 2015 Stock Incentive Plan (the “Plan”) provides for granting stock options, restricted 
stock awards and performance awards to directors, officers and employees of the Company. A total of 10.5 million shares of 
common stock have been authorized for issuance under the Plan. At December 31, 2018, the Company had 1.4 million shares 
of common stock available for future grants. Shares issued as a result of awards granted under the Plan are generally new 
common shares. 

Restricted stock awards. All restricted shares are legally issued and outstanding. If an employee terminates employment 
prior  to  the  restriction lapse  date,  the  awarded  shares are forfeited and  cancelled  and  are  no  longer considered  issued  and 
outstanding. A summary of the Company’s restricted stock award activity for the year ended December 31, 2018 is presented

For  restricted  stock  awards  granted,  stock-based  compensation  expense  is  recognized  in  the  Company’s  consolidated 
financial statements on an accelerated basis over the awards’ vesting periods based on their grant date fair values. The restricted 
stock-based compensation awards generally vest over a period ranging from one to five years. The Company utilizes the average 
of the high and low stock prices on the grant date for the fair value of restricted stock.

Performance  unit  awards.  During  the  years  ended  December  31,  2018,  2017  and  2016,  the  Company  awarded 
performance units to its officers under the Plan. The number of shares of common stock that will ultimately be issued will be 
determined by a combination of (i) comparing the Company’s total shareholder return relative to the total shareholder return of 
a predetermined group of peer companies at the end of the performance period and (ii) the Company’s absolute total shareholder 
return at the end of the performance period. The performance period is 36 months. The grant date fair value was determined 
using  the  Monte  Carlo  simulation  method  and  is  being  expensed  ratably  over  the  performance  period.  Expected  volatilities 
utilized in the model were estimated using a historical period consistent with the remaining performance period of approximately 
three years. The risk-free interest rate was based on the U.S. Treasury rate for a term commensurate with the expected life of 
the grant.  

The Company used the following assumptions to estimate the fair value of performance unit awards granted during the 

years ended December 31, 2018, 2017 and 2016:

Note 8. Disclosures about fair value measurements 

The Company uses a valuation framework based upon inputs that market participants use in pricing an asset or liability, 
which are classified into two categories: observable inputs and unobservable inputs. Observable inputs represent market data 
obtained from independent sources, whereas unobservable inputs reflect a company’s own market assumptions, which are used 
if observable inputs are not reasonably available without undue cost and effort. These two types of inputs are further prioritized 
into the following fair value input hierarchy: 

Level 1:  Unadjusted  quoted  prices  in  active  markets  that  are  accessible  at  the  measurement  date  for  identical, 
unrestricted assets or liabilities. The Company considers active markets to be those in which transactions for 
the assets or liabilities occur in sufficient frequency and volume to provide pricing information on an ongoing 
basis. 

Level 2:  Quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for 
substantially the full term of the asset or liability. This category includes those derivative instruments that the 
Company  values  using  observable  market  data.  Substantially  all  of  these  inputs  are  observable  in  the 
marketplace throughout the full term of the derivative instrument, can be derived from observable data, or 
supported by observable levels at which transactions are executed in the marketplace. Level 2 instruments 
primarily include non-exchange traded derivatives such as over-the-counter commodity price swaps, basis 
swaps, collars and floors, investments and interest rate swaps. The Company’s valuation models are primarily 
industry-standard  models that  consider  various  inputs  including:  (i) quoted  forward  prices  for commodities, 
(ii) time  value,  (iii) current  market  and  contractual  prices  for  the  underlying  instruments  and  (iv)  volatility 
factors, as well as other relevant economic measures. 

Level 3:  Prices or valuation models that require inputs that are both significant to the fair value measurement and less 
observable from objective sources (i.e., supported by little or no market activity). The Company’s valuation 
models are primarily industry-standard models that consider various inputs including: (i) quoted forward prices 
for commodities, (ii) time value, (iii) current market and contractual prices for the underlying instruments and 
(iv) volatility factors, as well as other relevant economic measures.

(a)  The carrying value includes associated deferred loan costs and any discount. 

Credit facility. The carrying amount of the Company’s amended and restated credit facility (“Credit Facility”) approximates 

its fair value, as the applicable interest rates are variable and reflective of market rates. 

Senior notes. The fair values of the Company’s senior notes are based on quoted market prices. The debt securities are 

not actively traded and, therefore, are classified as Level 2 in the fair value hierarchy. 

Other financial assets and liabilities. The Company has other financial instruments consisting primarily of receivables, 
payables and other current assets and liabilities. The carrying amounts approximate fair value due to the short maturity of these 
instruments.

Derivative instruments. The fair value of the Company’s derivative instruments is estimated by management considering 
various factors, including closing exchange and over-the-counter quotations and the time value of the underlying commitments. 
Financial assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurement. 
The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment and may 
affect the valuation of the fair value of assets and liabilities and their placement within the fair value hierarchy levels. The following 
tables summarize (i) the valuation of each of the Company’s financial instruments by required fair value hierarchy levels and (ii) 
the gross fair value by the appropriate balance sheet classification, even when the derivative instruments are subject to netting 
arrangements and qualify for net presentation in the Company’s consolidated balance sheets at December 31, 2018 and 2017.

Concentrations of credit risk. At December 31, 2018, the Company’s primary concentrations of credit risk are the risk of 
collecting accounts receivable and the risk of counterparties’ failure to perform under derivative obligations. See Note 13 for 
information regarding the Company’s major customers and derivative counterparties. 

The Company has entered into International Swap Dealers Association Master Agreements (“ISDA Agreements”) with each 
of its derivative counterparties. The terms of the ISDA Agreements provide the Company and the counterparties with rights of 
set-off upon the occurrence of defined acts of default by either the Company or a counterparty to a derivative, whereby the party 
not in default may set off all derivative liabilities owed to the defaulting party against all derivative asset receivables from the 
defaulting party. See Note 9 for additional information regarding the Company’s derivative activities.

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis 

Certain  assets  and  liabilities  are  reported  at  fair  value  on  a  nonrecurring  basis  in  the  Company’s  consolidated  balance 

sheets. The following methods and assumptions were used to estimate the fair values:  

Impairments of long-lived assets – The Company periodically reviews its long-lived assets to be held and used, including 
proved oil and natural gas properties and their integrated assets, whenever events or circumstances indicate that the carrying 
value of those assets may not be recoverable, for instance when there are declines in commodity prices or well performance. 
The Company reviews its oil and natural gas properties by depletion base. An impairment loss is indicated if the sum of the 
expected undiscounted future net cash flows is less than the carrying amount of the assets. If the estimated undiscounted future 
net cash flows are less than the carrying amount of the Company’s assets, it recognizes an impairment loss for the amount by 
which the carrying amount of the asset exceeds the estimated fair value of the asset.  

The Company calculates the expected undiscounted future net cash flows of its long-lived assets and their integrated assets 
using management’s assumptions and expectations of (i) commodity prices, which are based on the NYMEX strip, (ii) pricing 
adjustments  for  differentials,  (iii)  production  costs,  (iv)  capital  expenditures,  (v)  production  volumes,  (vi)  estimated  proved 
reserves  and  risk-adjusted  probable  and  possible  reserves,  and  (vii)  prevailing  market  rates  of  income  and  expenses  from 
integrated  assets.  At  December 31,  2018,  the  Company’s  estimates  of  commodity  prices  for  purposes  of  determining 
undiscounted  future cash  flows,  which  are  based  on the  NYMEX  strip,  ranged  from  a 2019  price  of  $47.09  per  barrel  of  oil 
increasing to a 2025 price of $53.10 per barrel of oil. Natural gas prices ranged from a 2019 price of $2.78 per Mcf of natural 
gas decreasing to a 2021 price of $2.61 per Mcf then rising to a 2025 price of $2.90 per Mcf of natural gas. Both oil and natural 
gas commodity prices for this purpose were held flat after 2025. The Company did not recognize any impairment loss during the 
years ended December 31, 2018 or 2017. 

The Company calculates the estimated fair values of its long-lived assets and their integrated assets using a discounted 
future cash flow model. Fair value assumptions associated with the calculation of discounted future net cash flows include (i) 
market estimates of commodity prices, (ii) pricing adjustments for differentials, (iii) production costs, (iv) capital expenditures, (v) 
production volumes, (vi) estimated proved reserves and risk-adjusted probable and possible reserves, (vii) prevailing market 
rates of income and expenses from integrated assets and (viii) discount rate. The expected future net cash flows are discounted 
using an annual rate of 10 percent to determine fair value. These are classified as Level 3 fair value assumptions.  

During the three months ended March 31, 2016, NYMEX strip prices declined as compared to December 31, 2015, and as 
a result the carrying amount of the Company’s Yeso field of approximately $3.4 billion exceeded the expected undiscounted 
future  net  cash  flows  resulting  in  a  non-cash  charge  against  earnings  of  approximately  $1.5  billion.  The  non-cash  charge 
represented the amount by which the carrying amount exceeded the estimated fair value of the assets. 

It is reasonably possible that the estimate of undiscounted future net cash flows of the Company’s long-lived assets may 
change in the future resulting in the need to impair carrying values. The primary factors that may affect estimates of future cash 
flows are (i) commodity prices including differentials, (ii) increases or decreases in production and capital costs, (iii) future reserve 
volume  adjustments,  both  positive  and  negative,  to  proved  reserves  and  appropriate  risk-adjusted  probable  and  possible 
reserves, (iv) results of future drilling activities and (v) changes in income and expenses from integrated assets.

Note 9. Derivative financial instruments 

The Company uses derivative financial instruments to manage its exposure to commodity price fluctuations. Commodity 
derivative instruments are used to (i) reduce the effect of the volatility of price changes on the oil and natural gas the Company 
produces and sells, (ii) support the Company’s capital budget and expenditure plans and (iii) support the economics associated 
with acquisitions. The Company does not enter into derivative financial instruments for speculative or trading purposes.  

The Company’s derivative financial instruments have historically consisted of oil and natural gas swaps and oil basis swaps. 
Swap contracts allow the Company to receive a fixed price and pay a floating market price to the counterparty for the hedged 
commodity. Basis swap contracts allow the Company to receive a fixed price differential between market indices for the price of 
oil. 

In connection with the RSP Acquisition, the Company assumed certain oil collar and three-way collar contracts. In these 
contracts, each collar has an established floor price and ceiling price, and certain collars also include a short put price (three-
way  collars).  When  the  settlement  price  is  below  the  established  floor  price,  the  Company  receives  an  amount  from  its 
counterparty equal to the difference between the settlement price and the floor price multiplied by the hedged contract volume. 
When the settlement price is above the established ceiling price, the Company pays its counterparty an amount equal to the 
difference between the settlement price and the ceiling price multiplied by the hedged contract volume. When the settlement 
price is between the established floor and the ceiling, no amounts are due to or from the counterparty. In case of a three-way 
collar, when the settlement price is below the short put price, the Company receives from its counterparty an amount equal to 
the difference of the floor price and the short put price multiplied by the hedged contract volume. 

The Company also enters into fixed-price forward physical power purchase contracts to manage the volatility of the price of 
power  needed  for  ongoing  operations.  The  Company  may  also  enter  into  physical  delivery  contracts  to  effectively  provide 
commodity price hedges. Because these physical contracts are not expected to be net cash settled, the Company has elected 
normal purchase or normal sale treatment and records these contracts at cost. 

The  Company does  not  designate its  derivative  instruments  to  qualify  for  hedge  accounting.  Accordingly,  the  Company 

reflects changes in the fair value of its derivative instruments in its consolidated statements of operations as they occur. 

The following table summarizes the amounts reported in earnings related to the commodity derivative instruments for the

(a) The oil derivative contracts are settled based on the NYMEX – WTI monthly average futures price. 
(b) The basis differential price is between Midland – WTI and Cushing – WTI. The majority of these contracts are settled on a calendar- 
month basis, while certain contracts assumed in connection with the RSP Acquisition are settled on a trading-month basis. 
(c) The natural gas derivative contracts are settled based on the NYMEX – Henry Hub last trading day futures price. 

Derivative  counterparties.    The  Company  uses  credit  and  other  financial  criteria  to  evaluate  the  creditworthiness  of 
counterparties  to  its  derivative  instruments.  The  Company  believes  that  all  of  its  derivative  counterparties  are  currently 
acceptable  credit  risks.  The  Company  is  not  required  to  provide  credit  support  or  collateral  to  any  counterparties  under  its 
derivative contracts, nor are they required to provide credit support to the Company. In September 2017, the Company elected 
to enter into an “Investment Grade Period,” as defined in Note 10, under the Credit Facility, which had the effect of releasing all 
collateral formerly securing the Credit Facility. Additionally, as a result of the Company’s Investment Grade Period election along 
with amendments to certain ISDA Agreements with the Company’s derivative counterparties, the Company’s derivatives are no 
longer secured. See Note 10 for additional information regarding the Credit Facility.

(a) For each of the twelve month periods beginning on January 15, 2020, 2021, 2022, 2023 and thereafter, these notes are 

callable at 103.281%, 102.188%, 101.094% and 100%, respectively. 

Credit Facility. The Credit Facility has a maturity date of May 9, 2022. At December 31, 2018, the Company’s commitments 

from its bank group were $2.0 billion.  

In  April  2017,  the  Company  amended  the  Credit  Facility  to  extend  the  maturity  date  and  decrease  unused  lender 
commitments. The amendment also lowered the corporate ratings floor sufficient to automatically terminate an Investment Grade 
Period under the Credit Facility from (i) “Ba1” to “Ba2” for Moody’s Investors Service, Inc. (“Moody’s”) and (ii) “BB+” to “BB” for 
S&P Global Ratings (“S&P”). 

The Company recorded a loss on extinguishment of debt of approximately $1 million in 2017 for the proportional amount of 
unamortized deferred loan costs associated with banks that are no longer in the Credit Facility syndicate as a result of the April 
2017 amendment. 

In September 2017, the Company elected to enter into an Investment Grade Period under the Credit Facility, which had the 
effect of releasing all collateral formerly securing the Credit Facility. If the Investment Grade Period under the Credit Facility 
terminates  (whether  automatically  due  to  a  downgrade  of  the  Company’s  credit  ratings  below  certain  thresholds  or  by  the 
Company’s election), the Credit Facility will once again be secured by a first lien on substantially all of the Company’s oil and 
natural gas properties and by a pledge of the equity interests in its subsidiaries. At December 31, 2018, certain of the Company’s 
100 percent owned subsidiaries are guarantors under the Credit Facility. 

During an Investment Grade Period, advances on the Credit Facility bear interest, at the Company’s option, based on (i) an 
alternative base rate, which is equal to the highest of (a) the prime rate of JPMorgan Chase Bank (5.5 percent at December 31, 
2018), (b) the federal funds effective rate plus 0.5 percent and (c) LIBOR plus 1.0 percent or (ii) LIBOR. The Credit Facility’s 
interest rates and commitment fees on the unused portion of the available commitment vary depending on the Company’s credit 
ratings from Moody’s and S&P. At the Company’s current credit ratings, LIBOR Rate Loans and Alternate Base Rate Loans bear 
interest margins of 150 basis points and 50 basis points per annum, respectively, and commitment fees on the unused portion 
of the available commitment are 25 basis points per annum. During the years ended December 31, 2018, 2017 and 2016, the 
Company incurred commitment fees on the unused portion of the available commitments of $5 million, $6 million and $8 million, 
respectively. The Company had $1.8 billion of unused commitments, net of letters of credit, under the Credit Facility at December 
31, 2018. 

The Credit Facility contains various restrictive covenants and compliance requirements, which include: 

•  maintenance  of  certain  financial  ratios,  including  maintenance  of  a  quarterly  ratio  of  consolidated  total  debt  to 
consolidated  earnings,  as  defined,  before  interest  expense,  income  taxes,  depletion,  depreciation,  and 
amortization, exploration expense and other non-cash income and expenses to be no greater than 4.25 to 1.0, and

Senior  notes.  Interest  on  the  Company’s  senior  notes  is  paid  in  arrears  semi-annually.  The  senior  notes  are  fully  and 
unconditionally guaranteed on a senior unsecured basis by certain of the Company’s 100 percent owned subsidiaries, subject 
to customary release provisions as described in Note 17, and rank equally in right of payments with one another.   

On July 2, 2018, the Company issued $1,600 million in aggregate principal amount of unsecured senior notes, consisting 
of $1,000 million in aggregate principal amount of 4.3% unsecured senior notes due 2028 (the “4.3% Notes”) and $600 million 
in aggregate principal amount of 4.85% unsecured senior notes due 2048 (the “4.85% Notes” and, together with the 4.3% Notes, 
the “Notes”). The 4.3% Notes were issued at a price equal to 99.660 percent of par, and the 4.85% Notes were issued at a price 
equal to 99.740 percent of par. The net proceeds of approximately $1,579 million were used to redeem and cancel all of RSP’s 
outstanding $700 million aggregate principal amount of 6.625% unsecured senior notes due 2022 (the “RSP 2022 Notes”) and 
$450 million aggregate principal amount of 5.25% unsecured senior notes due 2025 (the “RSP 2025 Notes” and, together with 
the RSP 2022 Notes, the “RSP Notes”). The Company made aggregate payments of approximately $1.2 billion to redeem and 
cancel the RSP Notes, including make-whole call premiums of approximately $35 million and $33 million for the RSP 2022 Notes 
and RSP 2025 Notes, respectively. The Company also paid accrued interest of approximately $14 million on the RSP Notes. 
The remaining proceeds, along with borrowings under the Credit Facility, were used to repay the $540 million of outstanding 
principal  under  RSP’s  revolving  credit  facility,  including  $1  million  in  accrued  interest.  See  Note  4  for  additional  information 
regarding the RSP Acquisition. 

In September 2017, the Company issued $1,800 million in aggregate principal amount of unsecured senior notes, consisting 
of $1,000 million in aggregate principal amount of 3.75% unsecured senior notes due 2027 (the “3.75% Notes”) and $800 million 
in aggregate principal amount of 4.875% unsecured senior notes due 2047 (the “4.875% Notes” and, together with the 3.75% 
Notes, the “2017 Notes”). The 3.75% Notes were issued at a price equal to 99.636 percent of par, and the 4.875% Notes were 
issued at a price equal to 99.749 percent of par. The Company received net proceeds of approximately $1,777 million. 

Additionally, in September 2017, the Company completed a cash tender offer (the “Tender Offer”) to purchase any and all 
of the outstanding $600 million aggregate principal amount of its 5.5% unsecured senior notes due 2022 and the outstanding 
$1,550 million aggregate principal amount of its 5.5% unsecured senior notes due 2023 (collectively, the “5.5% Notes”). The 
Company received tenders from the holders of approximately $1,232 million in aggregate principal amount, or approximately 
57.3 percent, of its outstanding 5.5% Notes in connection with the Tender Offer at a price of 102.934 percent of the unpaid 
principal amount plus accrued and unpaid interest to the settlement date. 

In connection with the Tender Offer, the Company redeemed the remaining outstanding 5.5% Notes not purchased in the 
Tender Offer at a price, including the make-whole premium as determined in accordance with the indentures, of 102.75 percent 
of the unpaid principal amount plus accrued and unpaid interest. Additionally in September 2017, the Company completed a 
satisfaction and discharge of the redeemed notes, where the Company prepaid interest to October 13, 2017. The Company 
used the net proceeds from the offering of the 2017 Notes, together with cash on hand and borrowings under its Credit Facility, 
to fund the Tender Offer and the satisfaction and discharge of its obligations under the indentures of the 5.5% Notes.

In December 2016, the Company issued $600 million in aggregate principal amount of 4.375% senior notes due 2025 at 
par, for which it received net proceeds of approximately $593 million. The Company used the net proceeds from the offering to 
fund the satisfaction and discharge of its obligations under the indenture of the $600 million outstanding principal amount of its 
6.5% unsecured senior notes due 2022 (the “6.5% Notes”) at a price equal to 103.25 percent of par. The early extinguishment 
price included the make-whole premium as determined in accordance with the indenture governing the 6.5% Notes. In December 
2016, the Company also paid interest of approximately $20 million on the 6.5% Notes through January 16, 2017.  

The Company recorded a loss on extinguishment of debt related to the 6.5% Notes of approximately $28 million for the year 
ended  December  31,  2016.  This  amount  includes  $20  million  associated  with  the  make-whole  premium  paid  for  the  early 
extinguishment  of  the  notes,  approximately  $7  million  of  unamortized  deferred  loan  costs  and  approximately  $1  million  of 
additional interest on the 6.5% Notes through January 16, 2017, which was paid in December 2016. 

In September 2016, the Company redeemed the $600 million outstanding principal amount of its 7.0% unsecured senior 
notes due 2021 (the “7.0% Notes”) at a price equal to 103.5 percent of par. The redemption price included the make-whole 
premium for the early redemption, as determined in accordance with the indenture governing the 7.0% Notes. The Company 
also paid accrued and unpaid interest on the 7.0% Notes through September 19, 2016, the redemption date. 

The Company recorded a loss on extinguishment of debt related to the redemption of the 7.0% Notes of approximately $28 
million for the year ended December 31, 2016. This amount includes $21 million associated with the make-whole premium paid 
for the early redemption of the notes and approximately $7 million of unamortized deferred loan costs.

Note 11. Commitments and contingencies 

Severance  agreements.    The  Company  has  entered  into  severance  and  change  in  control  agreements  with  all  of  its 
officers. The current annual salaries for the Company’s officers covered under such agreements total approximately $9 million. 

Indemnifications.  The Company has agreed to indemnify its directors and officers with respect to claims and damages 

arising from certain acts or omissions taken in such capacity. 

Legal actions.  The Company is a party to proceedings and claims incidental to its business. Assessing contingencies is 
highly  subjective  and  requires  judgment  about  uncertain  future  events.  When  evaluating  contingencies  related  to  legal 
proceedings,  the  Company  may  be  unable  to  estimate  losses  due  to  a  number  of  factors,  including  potential  defenses,  the 
procedural status of the matter in question, the presence of complex legal and/or factual issues, the ongoing discovery and/or 
development of information important to the matter. For material matters that the Company believes an unfavorable outcome is 
reasonably possible, it would disclose the nature of the matter and a range of potential exposure, unless an estimate cannot be 
made at this time. The Company does not believe that the loss for any other litigation matters and claims that are reasonably 
possible to occur will have a material adverse effect on its financial position, results of operations or liquidity. The Company will 
continue  to  evaluate  proceedings  and  claims  involving  the  Company  on  a  regular  basis  and  will  establish  and  adjust  any 
estimated accruals as appropriate. 

Severance tax, royalty and joint interest audits.  The Company is subject to routine severance, royalty and joint interest 
audits  from  regulatory  bodies  and  non-operators  and  makes  accruals  as  necessary  for  estimated  exposure  when  deemed 
probable  and  estimable.  Additionally,  the  Company  is  subject  to  various  possible  contingencies  that  arise  primarily  from 
interpretations affecting the oil and natural gas industry. Such contingencies include differing interpretations as to the prices at 
which oil and natural gas sales may be made, the prices at which royalty owners may be paid for production from their leases, 
allowable costs under joint interest arrangements and other matters. Although the Company believes that it has estimated its 
exposure with respect to the various laws and regulations, administrative rulings and interpretations thereof, adjustments could 
be required as new interpretations and regulations are issued. 

Regulatory  and  environmental  compliance.  Regulatory  liabilities  relate  to  acquisitions  where  additional  equipment  is 
necessary  to  have  facilities  compliant  with  local,  state  and  federal  obligations.  Environmental  expenditures  that  relate  to  an 
existing condition caused by past operations and that have no future economic benefits are expensed. Liabilities for expenditures 
of  a  noncapital  nature  are  recorded  when  environmental  assessment  and/or  remediation  is  probable  and  the  costs  can  be 
reasonably  estimated.  Such  liabilities  are  generally  undiscounted  unless  the  timing  of  cash  payments  is  fixed  and  readily 
determinable.  Environmental  liabilities  normally  involve  estimates  that  are  subject  to  revision  until  settlement  occurs.  At 
December 31, 2018 and 2017, the Company had regulatory and environmental liabilities of approximately $26 million and $3 
million, respectively, which are included in other current liabilities on the accompanying consolidated balance sheets. During the 
years  ended  December  31,  2018,  2017  and  2016,  the  Company  recognized  regulatory  and  environmental  charges  of 
approximately $23 million, $9 million and $7 million, respectively, which are included in oil and natural gas production expense 
in the accompanying consolidated statements of operations.

Commitments. The Company periodically enters into contractual arrangements under which the Company is committed to 
expend funds. These contractual arrangements relate to purchase agreements the Company has entered into including drilling 
commitments,  water  commitment  agreements,  throughput  volume  delivery  commitments,  fixed  and  variable  power 
commitments,  sand  commitment  agreements,  fixed  asset  commitments  and  maintenance  commitments.  The  following  table

Throughput sales commitment. In May 2018, the Company entered into a one-year term oil marketing contract with a 
third-party purchaser. The contract requires the Company to deliver not less than seven thousand barrels per day. Should there 
be a delivery shortfall in any given month, the Company retains an option to deliver the shortfall volume in any two subsequent 
months;  however,  failure  to  meet  this  volume  delivery  commitment  would  result  in  a  penalty  equal  to  the  volume  shortfall 
multiplied  by  the  then  market  price  for  oil.  If  production  is  not  sufficient  to  meet  the  sales  commitment,  the  Company  may 
purchase commodities in the market to satisfy its commitment.

Note 12. Income taxes  

The Company uses an asset and liability approach for financial accounting and reporting for income taxes. The Company’s 
objectives of accounting for income taxes are to recognize (i) the amount of taxes payable or refundable for the current year and 
(ii)  deferred  tax  liabilities  and  assets  for  the  future  tax  consequences  of  events  that  have  been  recognized  in  its  financial 
statements or tax returns. The Company and its subsidiaries file a federal corporate income tax return on a consolidated basis. 
The tax returns and the amount of taxable income or loss are subject to examination by federal and state taxing authorities. 

The Company’s income tax expense (benefit) attributable to income (loss) from operations consisted of the following for the 

years ended December 31, 2018, 2017 and 2016:

On December 22, 2017, the President signed into law the TCJA, which enacted significant changes to federal income tax 
laws, including a decrease in the federal corporate income tax rate from 35 percent to 21 percent, which was effective January 
1, 2018. In accordance with SAB 118, the Company recorded, based on reasonable estimates, a $398 million decrease to its 
income  tax  provision  at  December  31,  2017.  This provisional  amount  related  to the  re-measurement  of certain  deferred  tax 
assets and liabilities based on the rates at which they are expected to reverse in the future. At December 31, 2018, the Company 
completed its accounting for all of the enactment-date tax effects of the TCJA and recognized an adjustment of $7 million which 
is included as a component of income tax expense.  

The Company monitors changes in enacted tax rates for the jurisdictions in which it operates. The Company monitors its 
state tax apportionment footprint and makes updates for changes in its projected activity, including changes in budgets and 
drilling plans and changes as a result of acquisitions or divestitures. Based upon the Company’s projected future activity for the 
states in which it conducts business, the timing for when it anticipates its deferred tax items to become taxable and enacted tax 
rates at such time deferred items become taxable, the Company revised its estimated state tax rate, primarily due to the impact

of the RSP Acquisition. As a result, the Company recorded an income tax benefit of approximately $8 million, net of federal tax 
benefit, in its income tax provision for the year ended December 31, 2018. The Company did not revise its estimated state rate 
and, as  such,  did  not  record an  additional  deferred state  tax  benefit  for  the  year  ended December 31, 2017.  The  Company 
revised  its  estimated  state  rate  and  recorded  a  deferred  state  tax  benefit  of  approximately  $21  million  for  the  year  ended 
December 31, 2016.  

The Company recorded an income tax benefit of approximately $12 million and $6 million for the years ended December 
31, 2018 and 2017, respectively, related to excess tax benefits on stock-based awards, which are recorded in the income tax 
provision pursuant to ASU 2016-09 adopted on January 1, 2017. 

At December 31, 2018, the Company had approximately $2.2 billion of federal net operating losses (“NOLs”), including $516 
million  acquired  from  RSP,  net  of  reduction  for  unrecognized  tax  benefits.  At  December  31,  2018,  the  Company  had 
approximately $1.5 billion of NOLs that will begin to expire in the tax year 2034 but are allowable as a deduction against 100 
percent of future taxable income since they were generated prior to the effective date of the limitations imposed by the TCJA. 
Additionally, the Company has estimated an apportioned New Mexico NOL of approximately $520 million that will begin to expire 
in 2036.  

The tax effects of temporary differences that give rise to significant portions of the deferred tax assets and deferred tax 

liabilities were as follows:

Deferred tax assets: 

Stock-based compensation  
Derivative instruments  
Asset retirement obligation

On July 19, 2018, the Company completed the RSP Acquisition. For federal income tax purposes, the transaction qualified 
as a tax-free merger whereby the Company acquired carryover tax basis in RSP’s assets and liabilities. As of December 31, 
2018, the Company recorded an opening balance sheet deferred tax liability of $515 million, which includes a deferred tax asset 
related to tax attributes acquired from RSP. The acquired income tax attributes primarily consist of NOLs and research and 
development credits that are subject to an annual limitation under Internal Revenue Code Section 382. The Company expects 
that these tax attributes will be fully utilized prior to expiration. The Company had net deferred tax liabilities of approximately 
$1.8 billion and $687 million as of December 31, 2018 and 2017, respectively. 

Pursuant to management’s assessment, the Company does not believe a cumulative ownership change has occurred as 
of December 31, 2018. As such, Section 382 of the Internal Revenue Code of 1986, as amended, is not expected to limit the 
Company’s ability to utilize its NOL carryforward as of December 31, 2018. As noted above, tax attributes acquired from RSP 
include  NOLs  and  credits  subject  to  an  annual  limitation  under  Section  382;  however,  the  Company  expects  that  these  tax 
attributes will be fully utilized prior to expiration.

December 31, 2018, 2017 and 2016 

Management monitors company-specific, oil and natural gas industry and worldwide economic factors and assesses the 
likelihood that the Company’s NOLs and other deferred tax attributes will be utilized prior to their expiration. At December 31, 
2018,  management  considered  all  factors  including  the  expected  reversal  of  deferred  tax  liabilities  (including  the  impact  of 
available carryforward periods), historical operating income tax planning strategies and projected future taxable income. Based 
on  the  results  of  the  assessment,  a  valuation  allowance  of  $3  million  was  recorded  related  to  charitable  contribution 
carryforwards not anticipated to be utilized prior to expiration. Management determined that it is more likely than not that the 
Company will realize its remaining deferred tax assets.  

The following table sets forth changes in the Company’s unrecognized tax benefits: 

(in millions)

The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position 
will be sustained upon examination by the taxing authorities based upon the technical merits of the position. At December 31, 
2018, the Company had unrecognized tax benefits of approximately $63 million, primarily related to research and development 
credits. If all or a portion of the unrecognized tax benefit is sustained upon examination by the taxing authorities, the tax benefit 
will be recognized as a reduction to the Company's deferred tax liability and will affect the Company's effective tax rate in the 
period  recognized.  The  timing  as  to  when  the  Company  will  substantially  resolve  the  uncertainties  associated  with  the 
unrecognized tax benefit is uncertain, but the Company does not expect that a change in the unrecognized tax benefit within the 
next 12 months would have a material impact to the financial statements. 

The Company has not recognized any interest or penalties relating to unrecognized tax benefits in its consolidated financial 
statements. Any interest or penalties would be recognized as a component of income tax expense. In the Company’s major tax 
jurisdictions, the earliest year open to examination is 2013.

Note 13. Major customers and derivative counterparties 

Sales  to  major customers. The  Company’s share of  oil  and  natural  gas  production  is sold  to  various  purchasers.  The 
Company is of the opinion that the loss of any one purchaser would not have a material adverse effect on the ability of the 
Company to sell its oil and natural gas production. 

The following purchasers individually accounted for 10 percent or more of the consolidated oil and natural gas revenues 

during the years ended December 31, 2018, 2017 and 2016:

Derivative  counterparties. The  Company  uses  credit  and  other  financial  criteria  to  evaluate  the  creditworthiness  of 
counterparties  to  its  derivative  instruments.  The  Company  believes  that  all  of  its  derivative  counterparties  are  currently 
acceptable  credit  risks.  The  Company  is  not  required  to  provide  credit  support  or  collateral  to  any  counterparties  under  its 
derivative contracts, nor are they required to provide credit support to the Company.  

At December 31, 2018, the Company had a net asset position of $695 million as a result of outstanding derivative contracts 
which are reflected in the accompanying consolidated balance sheets. The Company assessed the balances held by each of its 
derivative counterparties for concentration risk and noted balances of approximately $151 million, $92 million and $84 million 
with JP Morgan, Citigroup and Wells Fargo, respectively. 

Note 14. Related party transactions 

The Company paid royalties on certain properties to a partnership in which a director of the Company is the general partner 
and  owns  a  3.5  percent  partnership  interest.  These  payments  were  reported  in  the  Company’s  consolidated  statements  of 
operations and totaled approximately $8 million, $7 million and $4 million for the years ended December 31, 2018, 2017 and 
2016, respectively.

Note 15. Earnings per share 

The Company uses the two-class method of calculating earnings per share because certain of the Company’s unvested 

share-based awards qualify as participating securities. 

The  Company’s  basic  earnings  per  share  attributable  to  common  stockholders  is  computed  as  (i)  net  income  (loss)  as 
reported,  (ii)  less  participating  basic  earnings  (iii)  divided  by  weighted  average  basic  common  shares  outstanding.  The 
Company’s diluted earnings per share attributable to common stockholders is computed as (i) basic earnings attributable to 
common stockholders, (ii) plus reallocation of participating earnings (iii) divided by weighted average diluted common shares 
outstanding. 

The following table reconciles the Company’s earnings from operations and earnings attributable to common stockholders 
to the basic and diluted earnings used to determine the Company’s earnings per share amounts for the years ended December 
31, 2018, 2017 and 2016, respectively, under the two-class method:

(a)  Unvested restricted stock awards represent participating securities because they participate in nonforfeitable dividends or 
distributions with the common equity holders of the Company. Participating earnings represent the distributed earnings of 
the Company attributable to the participating securities. Unvested restricted stock awards do not participate in undistributed 
net losses as they are not contractually obligated to do so.

Note 17.  Subsidiary guarantors 

At December 31, 2018, certain of the Company’s 100 percent owned subsidiaries have fully and unconditionally guaranteed 
the Company’s senior notes. The indentures governing the Company’s senior notes provide that the guarantees of its subsidiary 
guarantors  will  be  released  in  certain  customary  circumstances  including  (i)  in connection  with  any  sale,  exchange  or  other 
disposition,  whether  by  merger,  consolidation  or  otherwise, of  the  capital  stock of  that  guarantor  to  a  person  that  is  not  the 
Company or a restricted subsidiary of the Company, such that, after giving effect to such transaction, such guarantor would no 
longer constitute a subsidiary of the Company, (ii) in connection with any sale, exchange or other disposition (other than a lease) 
of all or substantially all of the assets of that guarantor to a person that is not the Company or a restricted subsidiary of the 
Company, (iii) upon the merger of a guarantor into the Company or any other guarantor or the liquidation or dissolution of a 
guarantor,  (iv)  if  the  Company  designates  any  restricted  subsidiary  that  is  a  guarantor  to  be  an  unrestricted  subsidiary  in 
accordance with the indenture, (v) upon legal defeasance or satisfaction and discharge of the indenture and (vi) upon written 
notice of such release or discharge by the Company to the trustee following the release or discharge of all guarantees by such 
guarantor of any indebtedness that resulted in the creation of such guarantee, except a discharge or release by or as a result of 
payment under such guarantee. 

See Note 10 for a summary of the Company’s senior notes. In accordance with practices accepted by the SEC, the Company 
has prepared condensed consolidating financial statements in order to quantify the assets, results of operations and cash flows 
of such subsidiaries as subsidiary guarantors. In addition, certain of the Company’s subsidiaries do not guarantee the Company’s 
senior  notes  and  are  included  in  the  Company’s  consolidated  financial  statements.  These  entities  are  100  percent  owned 
subsidiaries and are referred to as “Subsidiary Non-Guarantors” in the tables below. An additional entity did not guarantee the 
Company’s senior notes at December 31, 2017. This entity was a VIE that was formed to effectuate a tax-free exchange of 
assets.  During  2018,  the  Reverse  Exchange  1031  was  completed  and  all  assets  and  liabilities  attributable  to  the  VIE  were 
conveyed to the Company. This entity did not guarantee the Company’s senior notes until the conveyance was completed. See 
Note 5 for additional information regarding the completion of the Reverse 1031 Exchange. The Company’s less than 100 percent 
owned subsidiaries, primarily equity method investments, do not guarantee the Company’s senior notes. 

The  following  condensed  consolidating  balance  sheets  at  December  31,  2018  and  2017,  condensed  consolidating 
statements of operations and condensed consolidating statements of cash flows for the years ended December 31, 2018, 2017 
and  2016,  present  financial  information  for  Concho  Resources  Inc.  as  the  parent  on  a  stand-alone  basis  (carrying  any 
investments in subsidiaries under the equity method), financial information for the subsidiary guarantors on a stand-alone basis 
(carrying any investment in non-guarantor subsidiaries under the equity method), financial information for the subsidiary non-
guarantors on a stand-alone basis and the consolidation and elimination entries necessary to arrive at the information for the 
Company  on  a  consolidated  basis.  All  current  and  deferred  income  taxes  are  recorded  on  Concho  Resources  Inc.,  as  the 
subsidiaries are flow-through entities for income tax purposes. The subsidiary guarantors and subsidiary non-guarantors are not 
restricted from making distributions to the Company.

December 31, 2018, 2017 and 2016 

Note 18.  Subsequent events 

Dividends. On February 19, 2019, the Company’s board of directors declared a cash dividend of $0.125 per share for the 
first quarter of 2019. The total cash dividend, including the cash dividend on unvested restricted stock awards, of $25 million is 
expected to be paid on March 29, 2019. Any payment of future dividends will be at the discretion of the Company’s board of 
directors and will depend on, among other things, the Company’s earnings, financial condition, capital requirements, level of 
indebtedness,  statutory  and  contractual  restrictions  applying  to  the  payment  of  dividends  and  other  considerations  that  the 
Company’s board of directors deems relevant. Covenants contained in the Company’s agreement governing its Credit Facility 
and the indentures governing the Company’s senior notes could limit the payment of dividends. 

Marketing contract. Consistent with the Company’s strategy of diversifying its oil pricing, in January 2019, the Company 
entered  into  a  firm  sales  agreement  with  a  third-party  purchaser.  The  purchaser  provides  an  integrated  transportation  and 
marketing strategy, including ample dock capacity. The agreement has a term that ends five years after the startup of Cactus II 
Pipeline system and requires the Company to deliver 50,000 barrels of oil per day that will receive waterborne market pricing. 

New  commodity  derivative  contracts.  After  December  31,  2018,  the  Company  entered  into  the  following  derivative 

contracts to hedge additional amounts of estimated future production:

Reserve Quantity Information 

The following information represents estimates of the Company’s proved reserves. The pricing that was used for estimates 
of the Company’s reserves as of December 31, 2018 was based on the SEC pricing of $62.04 per Bbl West Texas Intermediate 
posted oil price and $3.10 per MMBtu Henry Hub spot natural gas price.  

Subject to limited exceptions, proved undeveloped reserves may only be recognized if they relate to wells scheduled to be 
drilled within five years of the date of their initial recognition. This rule limited, and may continue to limit, the Company’s potential 
to  record  additional  proved  undeveloped  reserves as  it  pursues  its  drilling  program, particularly  as  it develops  its significant 
acreage in the Permian Basin of Southeast New Mexico and West Texas. Moreover, the Company may be required to write 
down its proved undeveloped reserves if it does not drill on those reserves within the required five-year timeframe. All of the 
Company’s  recorded  proved  undeveloped  reserves  are  scheduled  to  be  drilled  within  five  years  of  the  date  of  their  initial 
recognition. 

The Company’s proved oil and natural gas reserves are all located in the United States, primarily in the Permian Basin of 
Southeast New Mexico and West Texas. All of the estimates of the proved reserves at December 31, 2018, 2017 and 2016 are 
based  on  reports  prepared  by  Cawley,  Gillespie  &  Associates,  Inc.  and  Netherland,  Sewell  &  Associates,  Inc.,  independent 
petroleum engineers. Proved reserves were estimated in accordance with the guidelines established by the SEC and the FASB. 

The following table summarizes the prices utilized in the reserve estimates for 2018, 2017 and 2016. Commodity prices 

utilized for the reserve estimates prior to adjustments for location, grade and quality are as follows:

Oil and natural gas reserve quantity estimates are subject to numerous uncertainties inherent in the estimation of quantities 
of proved reserves and in the projection of future rates of production and the timing of development expenditures. The accuracy 
of such estimates is a function of the quality of available data and of engineering and geological interpretation and judgment. 
Results of subsequent drilling, testing and production may cause either upward or downward revision of previous estimates. 
Further,  the  volumes  considered  to  be  commercially  recoverable  fluctuate  with  changes  in  prices  and  operating  costs.  The 
Company emphasizes that reserve estimates are inherently imprecise and that estimates of new discoveries are more imprecise 
than  those  of  currently  producing  oil  and  natural  gas  properties.  Accordingly,  these  estimates  are  expected  to  change  as 
additional information becomes available in the future.

For the year ended December 31, 2018: 

Extensions  and  discoveries.  Extensions  and  discoveries  of  approximately  226  MMBoe  are  primarily  the  result  of  the 
Company’s  continued  success  from  its  horizontal  drilling  programs  in  the  Company’s  operating  areas.  Proved  developed 
reserves  increased  approximately  87  MMBoe  due  to  the  Company’s  drilling  activity  in  2018.  Based  upon  this  activity, 
approximately 139 MMBoe of new proved undeveloped locations were added.  

Purchases and sales of minerals-in-place. The Company’s purchases of minerals-in-place were primarily the result of the 
RSP Acquisition in July 2018 which added approximately 275 MMBoe. The remainder of the purchases of minerals-in-place was 
primarily the result of certain acquisitions and nonmonetary transactions during 2018, which added approximately 25 MMBoe in 
the Midland Basin and 8 MMBoe in the Delaware Basin. The Company’s sales of minerals-in-place were primarily the result of 
various divestitures and nonmonetary transactions during 2018. 

Revisions  of  previous estimates.  Revisions  of  previous estimates  are  primarily  composed  of  (i)    77  MMBoe  of  negative 
revisions primarily due to proved undeveloped reserves reclassified to unproved, (ii) 15 MMBoe of net negative performance 
and  other  revisions  and  (iii)  18  MMBoe  of  positive  price  revisions.  As  the  Company  continues  to  transition  its  development 
program to large-scale projects and evaluate and analyze its producing oil and natural gas properties and drilling prospects, 
certain properties were no longer expected to be developed within five years of the date of their initial recognition and were 
removed from the Company’s current drilling plans. This includes certain properties that were identified to have a lower liquids 
content  and  certain  non-operated  properties  that  the  Company  reclassified  due  to  the  uncertainty  regarding  the  timing  of 
development. Net negative performance and other revisions primarily related to 27 MMBoe of downward revisions to certain 
proved developed producing properties in the Yeso field, partially offset by other positive performance revisions. Positive price 
revisions were the result of an increase in the oil and natural gas prices utilized in the Company’s reserve estimates at December 
31, 2018 as compared to December 31, 2017.  

For the year ended December 31, 2017:  

Purchases and sales of minerals-in-place. The Company’s purchases of minerals-in-place are composed of approximately 11 
MMBoe from the July 2017 Midland Basin acquisition, 8 MMBoe from the January 2017 Delaware Basin acquisition and 15 
MMBoe  from  various  other  acquisitions  throughout  the  year.  The  Company’s  sales  of  minerals-in-place  are  composed  of 
approximately 4 MMBoe from various divestitures throughout the year. 

Extensions  and  discoveries.  Extensions  and  discoveries  of  approximately  174  MMBoe  are  primarily  the  result  of  the 
Company’s continued success from its extension and infill horizontal drilling programs in its operating areas. Proved developed

reserves increased approximately 82 MMBoe due to the Company’s exploratory drilling activity in 2017. Based upon this activity, 
approximately 92 MMBoe of new proved undeveloped locations were added.  

Revisions of previous estimates. Revisions of previous estimates are composed of (i) 61 MMBoe of negative revisions due 
to proved undeveloped reserves reclassified to unproved reserves because they are no longer expected to be developed within 
five years of the date of their initial recognition as required by SEC rules due to a shift in the Company’s capital program to 
generally focus more on large-scale development projects in certain areas, (ii) 29 MMBoe of positive price revisions and (iii) 18 
MMBoe of positive technical and performance revisions.  

For the year ended December 31, 2016:  

Purchases and sales of minerals-in-place. The Company’s purchases of minerals-in-place are composed of approximately 
42 MMBoe from the October 2016 Reliance Acquisition, 15 MMBoe from the March 2016 Southern Delaware Basin acquisition 
and 2 MMBoe from various other acquisitions throughout the year. The Company’s sales of minerals-in-place are composed of 
approximately 8 MMBoe from various divestitures throughout the year. 

Extensions  and  discoveries.  Extensions  and  discoveries  of  approximately  125 MMBoe  are  primarily  the  result  of  the 
Company’s continued success from its extension and infill horizontal drilling programs in its operating areas. Proved developed 
reserves  increased  approximately  61  MMBoe  due  to  the  Company’s  exploratory  drilling  activity.  Based  upon  this  activity, 
approximately 64 MMBoe of new proved undeveloped locations were added, of which the majority are one offset location from 
an existing producing well.  

Revisions of previous estimates. Revisions of previous estimates are comprised of (i) 57 MMBoe of negative revisions due 
to proved undeveloped reserves reclassified to unproved reserves because they are no longer expected to be developed within 
five years of the date of their initial recognition and (ii) 30 MMBoe of negative price revisions, partially offset by 63 MMBoe of 
net positive revisions related to lower lease operating expense estimates. The 57 MMBoe of proved undeveloped reserves in 
item (i) above are outside the five-year development window primarily due to results the Company has obtained during 2016 
related to increased testing and implementation of new technologies that allows for drilling extended length laterals. The results 
are generally highly successful and provide sufficient data that substantiates drilling extended length laterals is generally a more 
efficient process than shorter lateral drilling to recover reserves. The results also generally confirm that the drilling of longer 
laterals is feasible on a large scale and substantially decreases the risks associated with a drilling program more focused on 
extended  length  laterals.  Consequently,  the  Company  shifted  its  capital  program  to  focus  on  drilling  more  extended  length 
laterals. 

Standardized Measure of Discounted Future Net Cash Flows 

The standardized measure of discounted future net cash flows is computed by applying the 12-month unweighted average 
of the first-day-of-the-month pricing for oil and natural gas (with consideration of price changes only to the extent provided by 
contractual  arrangements)  to  the  estimated  future  production  of  proved  oil  and  natural  gas  reserves  less  estimated  future 
expenditures (based on year-end costs) to be incurred in developing and producing the proved reserves, discounted using a 
rate  of  10  percent  per  year  to  reflect  the  estimated  timing  of  the  future  cash  flows.  Future  income  taxes  are  calculated  by 
comparing undiscounted future cash flows to the tax basis of oil and natural gas properties plus available carryforwards and 
credits and applying the current tax rates to the difference. 

Discounted future cash flow estimates like those shown below are not intended to represent estimates of the fair value of 
oil and natural gas properties. Estimates of fair value would also consider probable and possible reserves, anticipated future oil 
and natural gas prices, interest rates, changes in development and production costs and risks associated with future production. 
Because of these and other considerations, any estimate of fair value is necessarily subjective and imprecise.

Item 9.  Changes in and Disagreements with Accountants on Accounting and Financial Disclosure 

We had no changes in, and no disagreements with, our accountants on accounting and financial disclosure. 

Item 9A. Controls and Procedures 

Evaluation  of  Disclosure  Controls  and  Procedures.  As  required  by  Rule 13a-15(b)  of  the  Exchange  Act,  we  have 
evaluated, under the supervision and with the participation of our management, including our principal executive officer and 
principal financial officer, the effectiveness of the design and operation of our disclosure controls and procedures (as defined in 
Rules 13a-15(e)  and  15d-15(e)  under  the  Exchange  Act)  as  of  the  end  of  the  period  covered  by  this  report.  Our  disclosure 
controls and procedures are designed to provide reasonable assurance that the information required to be disclosed by us in 
reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including our 
principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure 
and is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC. Based 
upon the evaluation, our principal executive officer and principal financial officer have concluded that our disclosure controls and 
procedures were effective at December 31, 2018 at the reasonable assurance level. 

Management’s Report on Internal Control over Financial Reporting. The management of the Company is responsible 
for establishing and maintaining adequate internal control over financial reporting. The Company’s internal control over financial 
reporting is a process designed under the supervision of the Company’s Chief Executive Officer and Chief Financial Officer to 
provide  reasonable  assurance  regarding  the  reliability  of  financial  reporting  and  the  preparation  of  the  Company’s  financial 
statements for external purposes in accordance with accounting principles generally accepted in the United States of America. 

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements in a 
timely manner. 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. 

As  of  December  31,  2018,  management  assessed  the  effectiveness  of  the  Company’s  internal  control  over  financial 
reporting  based  on  the  criteria  established  in  “Internal  Control  -  Integrated  Framework  (2013)”  issued  by  the  Committee  of 
Sponsoring Organizations of the Treadway Commission. Based on this assessment, management determined that the Company 
maintained  effective  internal  control  over  financial  reporting  at  December  31,  2018.  Management’s  assessment  of,  and 
conclusion  on,  the  effectiveness  of  internal  control  over  financial  reporting  did  not  include  the  internal  controls  of  the  entity 
acquired in the RSP Acquisition on July 19, 2018. RSP’s total assets represented approximately 40 percent of the Company’s 
consolidated total assets at December 31, 2018, and RSP’s revenues following the July 19, 2018 acquisition date represented 
approximately 12 percent of the Company’s consolidated total operating revenues for the year ended December 31, 2018. 

Grant Thornton LLP, the independent registered public accounting firm that audited the consolidated financial statements 
of the Company included in this annual report on Form 10-K, has issued its report on the effectiveness of the Company’s internal 
control over financial reporting at December 31, 2018. The report, which expresses an unqualified opinion on the effectiveness 
of  the  Company’s  internal  control  over  financial  reporting  at  December  31,  2018,  is  included  in this  Item  under  the  heading 
“Report of Independent Registered Public Accounting Firm.” 

Changes  in  Internal  Control  over  Financial  Reporting.  Management’s  assessment  of,  and  conclusion  on,  the 
effectiveness of internal control over financial reporting did not include the internal controls of the entities acquired in the RSP 
Acquisition. Under guidelines established by the SEC, companies are permitted to exclude acquisitions from their assessment 
of internal control over financial reporting for a period of up to one year following an acquisition while integrating the acquired 
company. We are  in  the  process  of  integrating  RSP’s and our  internal  controls  over  financial  reporting.  As  a  result  of these 
integration  activities,  certain  controls  will  be  evaluated  and  may  be  changed.  Except  as  noted  above,  there  have  been  no 
changes  in  our  internal control  over  financial reporting  (as  defined  in  Rule 13a-15(f) under  the  Exchange  Act) that  occurred 
during our last fiscal quarter that have materially affected or are reasonably likely to materially affect our internal control over 
financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

Board of Directors and Stockholders 
Concho Resources Inc. 

Opinion on internal control over financial reporting 
We have audited the internal control over financial reporting of Concho Resources Inc. (a Delaware corporation) and subsidiaries 
(the “Company”) as of December 31, 2018, based on criteria established in the 2013 Internal Control—Integrated Framework 
issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). 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 the 2013 Internal Control—Integrated Framework issued by COSO. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(“PCAOB”), the consolidated financial statements of the Company as of and for the year ended December 31, 2018, and our 
report dated February 20, 2019 expressed an unqualified opinion on those financial statements. 

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

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

Our audit of, and opinion on, the Company’s internal control over financial reporting does not include the internal control over 
financial reporting of RSP Permian, Inc., a wholly-owned subsidiary, whose financial statements reflect total assets and revenues 
constituting 40 and 12 percent, respectively, of the related consolidated financial statement amounts as of and for the year ended 
December  31,  2018.  As  indicated  in  Management’s  Report,  RSP  Permian,  Inc.  was  acquired  during  2018.  Management’s 
assertion on the effectiveness of the Company’s internal control over financial reporting excluded internal control over financial 
reporting of RSP Permian, Inc. 

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

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.

Forward-Looking Statements and Cautionary Statements

The  foregoing  contains  “forward-looking  statements”  within  the 
meaning of Section 27A of the Securities Act of 1933, as amended, 
and Section 21E of the Securities Exchange Act of 1934, as amended. 
All statements, other than statements of historical fact, included in 
this  annual  report  that  address  activities,  events  or  developments 
that Concho Resources Inc. (the “Company” or “Concho”) expects,  
believes or anticipates will or may occur in the future are forward-looking 
statements.  The  words  “estimate,”  “project,”  “predict,”  “believe,” 
“expect,” “anticipate,” “potential,” “could,” “may,” “enable,” “foresee,” 
“plan,” “will,” “guidance,” “outlook,” “goal” or other similar expressions 
that convey the uncertainty of future events or outcomes are intended  
to  identify  forward-looking  statements,  which  generally  are  not  
historical in nature. However, the absence of these words does not 
mean that the statements are not forward-looking. These statements 
are based on certain assumptions and analyses made by the Company 
based  on  management’s  experience,  expectations  and  perception 
of  historical  trends,  current  conditions,  current  plans,  anticipated 
future developments, expected financings and other factors believed 
to be appropriate. Forward-looking statements are not guarantees 
of  performance.  Although  the  Company  believes  the  expectations 
reflected  in  its  forward-looking  statements  are  reasonable  and  are 
based  on  reasonable  assumptions,  no  assurance  can  be  given  that 
these  assumptions  are  accurate  or  that  any  of  these  expectations 
will be achieved (in full or at all) or will prove to have been correct. 
Moreover, such statements are subject to a number of assumptions, 
risks and uncertainties, many of which are beyond the control of the 
Company,  which  may  cause  actual  results  to  differ  materially  from 
those implied or expressed by the forward-looking statements. These 
include the risk factors and other information discussed or referenced 
in the Company’s most recent Annual Report on Form 10-K and other 
filings with the U.S. Securities and Exchange Commission (the “SEC”). 
Any forward-looking statement speaks only as of the date on which 
such statement is made, and the Company undertakes no obligation 
to  correct  or  update  any  forward-looking  statement,  whether  as 
a  result  of  new  information,  future  events  or  otherwise,  except  as 
required by applicable law. Information on Concho’s website is not 
part of this annual report.

USE   OF  NON- GAAP  FINANCIAL MEASURES

To  supplement  the  presentation  of  the  Company’s  financial  results  
prepared  in  accordance  with  U.S.  Generally  Accepted  Accounting  
Principles  (“GAAP”),  this  annual  report  contains  certain  financial  
measures that are not prepared in accordance with GAAP, including 
adjusted  EBITDAX.  For  a  reconciliation  of  adjusted  EBITDAX  to  the 
most directly comparable measure calculated in accordance with GAAP, 
please  see  “Item  1.  Business — Non-GAAP  Financial  Measures  and  
Reconciliations” in our 2018 Annual Report on Form 10-K included herein.

This annual report also contains the non-GAAP term free cash flow. Free 
cash flow is cash flow provided by operating activities in excess of cash 
flow used in investing activities for additions to oil and gas properties.

The  SEC  requires  oil  and  natural  gas  companies,  in  their  filings  with 
the  SEC,  to  disclose  proved  reserves,  which  are  those  quantities  of 
oil and natural gas which, by analysis of geoscience and engineering 
data, can be estimated with reasonable certainty to be economically 
producible — from  a  given  date  forward,  from  known  reservoirs  and  
under existing economic conditions (using the trailing 12-month average 
first-day-of-the-month  prices),  operating  methods  and  government 

regulations — prior to the time at which contracts providing the right 
to operate expire, unless evidence indicates that renewal is reasonably 
certain, regardless of whether deterministic or probabilistic methods are 
used for the estimation. The SEC also permits the disclosure of separate 
estimates of probable or possible reserves that meet SEC definitions 
for such reserves; however, the Company currently does not disclose 
probable or possible reserves in its SEC filings.

In this annual report, proved reserves attributable to the Company at 
December 31, 2018, are estimated utilizing SEC reserve recognition 
standards  and  pricing  assumptions  based  on  the  trailing  12-month 
average  first-day-of-the-month  prices  of  $62.04  per  Bbl  of  oil  and 
$3.10 per MMBtu of natural gas. 

CAUTIONARY STATEMENTS RE GARDING RES OU R CE

Concho may use the terms “resource potential”, “horizontal resource” 
and similar phrases to describe estimates of potentially recoverable 
hydrocarbons that SEC rules prohibit from being included in filings 
with the SEC. These are based on analogy to Concho’s existing models 
applied to additional acres, additional zones and tighter spacing, and 
are Concho’s internal estimates of hydrocarbon quantities that may be 
potentially discovered through exploratory drilling or recovered with 
additional drilling or recovery techniques. These quantities may not 
constitute “reserves” within the meaning of the Society of Petroleum 
Engineers’  Petroleum  Resource  Management  System  or  SEC  rules. 
Such estimates and identified drilling locations have not been fully 
risked by Concho management and are inherently more speculative 
than proved reserves estimates. Actual locations drilled and quantities 
that may be ultimately recovered from Concho’s interests could differ 
substantially from these estimates. There is no commitment by Concho 
to drill all of the drilling locations that have been attributed to these 
quantities. Factors affecting ultimate recovery include the scope of 
Concho’s ongoing drilling program, which will be directly affected by 
the availability of capital, commodity prices, drilling and production 
costs, availability of drilling services and equipment, drilling results, 
lease  expirations,  transportation  constraints,  regulatory  approvals, 
actual  drilling  results,  including  geological  and  mechanical  factors 
affecting recovery rates, and other factors. Such estimates may change 
significantly as development of Concho’s oil and natural gas assets  
provides additional data. Concho’s production forecasts and expectations 
for future periods are dependent upon many assumptions, including 
estimates  of  production  decline  rates  from  existing  wells  and  the 
undertaking  and  outcome  of  future  drilling  activity,  which  may  be 
affected  by  significant  commodity  price  declines  or  drilling  cost  
increases or other factors that are beyond Concho’s control. Concho’s 
use of the term “premium resource” refers to assets with the capacity 
to produce at an internal rate of return that is greater than thirty-five 
percent based on sixty-dollar oil and three-dollar gas. Concho’s use of 
the term “horizontal resource” refers to hydrocarbons (or oil and gas 
resources) planned to be developed through the drilling of horizontal 
wellbores into the targeted subsurface reservoirs.
