Except for historical information contained herein, the statements in this document are forward-looking statements that are made pursuant to the Safe Harbor 
Provisions of the Private Securities Litigation Reform Act of 1995. Forward-looking statements and the business prospects of Pioneer Natural Resources Company 
are subject to a number of risks and uncertainties that may cause Pioneer’s actual results in future periods to differ materially from the forward-looking statements. 
These risks and uncertainties are described in Items 1, 1A, 7 and 7A and on page 5 of Pioneer’s Form 10-K included with this report.

“Drill bit finding and development cost per BOE” means the summation of exploration and development costs incurred divided by the summation of annual proved 
reserves, on a BOE basis, attributable to technical revisions of previous estimates (excluding proved undeveloped (PUD) reserves removed and price revisions), 
discoveries and extensions and improved recovery. Consistent with industry practice, future capital costs to develop proved undeveloped reserves are not included 
in costs incurred.

“Drill bit reserve replacement” is the summation of annual proved reserves, on a BOE basis, attributable to revisions of previous estimates (excluding PUD reserves 
removed and price revisions), discoveries and extensions and improved recovery divided by annual production of oil, natural gas liquids and gas, on a BOE basis.

Cautionary Note — In this report, Pioneer includes estimates of quantities of oil and gas using certain terms, such as “resource,” “resource potential,” 
“recoverable resource potential” and “recoverable reserves,” which terms include quantities that may not meet the definitions of “reserves” established by the 
U.S. Securities and Exchange Commission (“SEC”) and which the SEC prohibits companies from including in SEC filings. These estimates are by their nature subject 
to substantially greater risk of being recovered by Pioneer than are proved reserves. You are urged to consider closely the disclosures in the Company’s periodic 
filings with the SEC, which are available from the Company at the address on the back cover of this report and on the Company’s website at www.pxd.com.

Fellow Shareholders:

We entered 2013 with high expectations for 

Pioneer, our industry and U.S. energy growth. To 

reach Pioneer’s goals, we expected much from 

our people and from our assets, especially our 

acreage positions in two of the most prolific plays 

in the U.S., the Spraberry/Wolfcamp Shale in the 

Midland Basin of West Texas and the Eagle Ford

Shale in South Texas. We also expected the U.S. 

energy renaissance to continue—that our industry 

would continue to support our country’s economic 

recovery, provide strong job growth and advance 

U.S. energy security. I’m very pleased to report that 

results for 2013 were well beyond our expectations.

I consider 2013 to be the best year in Pioneer’s 

17-year history. Pioneer’s stock price increased by 

73%, and we were once again the top-performing 

energy stock in the S&P 500 Index. Our successful 

horizontal drilling programs in West Texas and 

South Texas contributed to another year of 

strong production growth and proved oil and 

natural gas reserve additions from the drill bit. 

The drilling program and continued emphasis 

on science activities in the Spraberry/Wolfcamp 

and Eagle Ford Shales significantly advanced our 

understanding of the resource potential within 

these two prolific plays, optimized our future 

development plans and added significant net 

asset value for our shareholders. These plays 

offer exceptional returns and tremendous growth 

opportunities for many years to come.

Drilling results in 2013, combined with geologic 

data from thousands of existing wells, allowed  

our geoscience team to further refine the potential 

of multiple prospective horizontal targets 

throughout Pioneer’s approximate 825,000 gross 

acre Spraberry/Wolfcamp Shale position. The 

team now estimates that our acreage position has 

an aggregate estimated resource potential of more

than 10 billion barrels oil equivalent (BOE),  

up almost 50% from the year-ago estimate of  

7 billion BOE.

The U.S. upstream oil and natural gas industry 

has defied previous forecasts that our country’s 

energy production had reached its peak and 

would be in constant decline. The U.S. energy 

renaissance continues to exceed expectations 

for production growth, economic stimulus and 

job creation. Oil production in the U.S. rose by a 

record 992,000 barrels a day, or more than 15%, to 

average 7.5 million barrels a day in 2013, according 

to the International Energy Agency, significantly 

exceeding its initial forecast.

During 2012, the United States overtook Russia 

as the world’s top natural gas producer, and 

U.S. natural gas production again increased in 

2013, averaging more than 70 billion cubic feet 

per day, according to the Energy Information 

Administration. As our industry expands U.S. 

oil and natural gas production beyond what is 

required for U.S. energy security, the discussion  

is appropriately shifting to the opportunity  

for exporting domestic oil and natural gas for 

the benefit of our international allies, thereby 

stabilizing and strengthening global energy  

supply while continuing to create jobs and 

economic benefits here at home.

Exceptional Progress in 2013

Spraberry/Wolfcamp Shale

Pioneer has a long history in the Midland Basin’s 

Spraberry field and has been the field’s most 

active driller for many years. The oil-rich Wolfcamp 

Shale lies below the Spraberry formation, and

these tight-rock formations.

Pioneer has a number of advantages in the 

Spraberry/Wolfcamp Shale as a result of our long

We utilized an average of seven rigs and drilled 

approximately 100 horizontal wells on this acreage

second half of the year to test downspacing to 

optimize ultimate oil recoveries.

In 2009, Pioneer completed its first horizontal 

well in the Eagle Ford Shale and was the second 

company to announce a discovery in this exciting

In the Eagle Ford Shale, Pioneer plans to drill 

approximately 110 horizontal wells in the liquids-

rich area of the play in 2014. Most of these wells 

will be drilled utilizing three-well and four-well 

pads. Based on strong results in 2013, the 2014 

wells will have longer lateral lengths and larger 

fracture stimulations. The ability to drill more wells 

with fewer rigs reflects the success of our efforts 

to control costs.

In the Rockies and Mid-Continent areas, we plan 

to continue our activities to control costs and 

maximize production as we continue to rely on

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 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 gas cap, proved oil 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 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.

"SEC" means the United States Securities and Exchange Commission.

"Standardized Measure" means the after-tax present value of estimated future net cash flows of proved reserves, determined 
in accordance with the rules and regulations of the SEC, using prices and costs employed in the determination of proved 
reserves and a ten percent discount rate.
"Proved undeveloped reserves" means 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) 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.

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

(iii) Under no circumstances shall estimates for proved undeveloped reserves be attributable to any acreage for which an 
application of fluid injection or other improved recovery technique is contemplated, unless such techniques have been proved 
effective by actual projects in the same reservoir or an analogous reservoir, or by other evidence using reliable technology 
establishing reasonable certainty.

"U.S." means United States.

PIONEER NATURAL RESOURCES COMPANY

PART I

ITEM 1.

BUSINESS

 General

The Company is a large independent oil and gas exploration and production company with operations in the United States. 
Pioneer is a holding company whose assets consist of direct and indirect ownership interests in, and whose business is conducted 
substantially through, its subsidiaries.  Pioneer's common stock is listed and traded on the NYSE under the ticker symbol "PXD."

The Company is a Delaware corporation formed in 1997. The Company's executive offices are located at 5205 N. O'Connor 
Blvd., Suite 200, Irving, Texas 75039. The Company's telephone number is (972) 444-9001. The Company maintains other offices 
in Anchorage, Alaska; Denver, Colorado; and Midland, Texas. At December 31, 2013, the Company had 4,203 employees, 1,985 
of whom were employed in other field and plant operations and 894 of whom were employed in vertical integration activities.

Available Information

Pioneer files or furnishes annual, quarterly and current reports, proxy statements and other documents with the SEC under 
the Securities Exchange Act of 1934 (the "Exchange Act"). The public may read and copy any materials that Pioneer files with 
the SEC at the SEC's Public Reference Room at 100 F Street, N.E., Washington, D.C. 20549. The public may obtain information 
on the operation of the Public Reference Room by calling the SEC at 1-800-SEC-0330. Also, the SEC maintains an Internet website 
that  contains  reports,  proxy  and  information  statements,  and  other  information  regarding  issuers,  including  Pioneer,  that  file 
electronically with the SEC. The public can obtain any documents that Pioneer files with the SEC at http://www.sec.gov.

The Company also makes available free of charge through its internet website (www.pxd.com) its Annual Reports on Form 
10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and, if applicable, amendments to those reports filed or 
furnished pursuant to Section 13(a) of the Exchange Act as soon as reasonably practicable after it electronically files such material 
with, or furnishes it to, the SEC.  

Mission and Strategies

The Company's mission is to enhance shareholder investment returns through strategies that maximize Pioneer's long-term 
profitability and net asset value. The strategies employed to achieve this mission are predicated on maintaining financial flexibility, 
capital allocation discipline and enhancing net asset value through accretive drilling programs, joint ventures and acquisitions. 
These strategies are anchored by the Company's interests in the long-lived Spraberry/Wolfcamp oil field; the liquid-rich Eagle 
Ford Shale play; the Hugoton and West Panhandle fields; and the Raton gas field; which together have an estimated remaining 
productive life in excess of 40 years. Underlying these fields are 92 percent of the Company's total proved oil and gas reserves as 
of December 31, 2013.

Business Activities

The Company is an independent oil and gas exploration and production company. Pioneer's purpose is to competitively 
and profitably explore for, develop and produce oil and gas reserves. In so doing, the Company sells homogenous oil, NGL and 
gas units that, except for geographic and relatively minor quality differences, cannot be significantly differentiated from units 
offered for sale by the Company's competitors. Competitive advantage is gained in the oil and gas exploration and development 
industry  by  employing  well-trained  and  experienced  personnel  who  make  prudent  capital  investment  decisions  based  on 
management direction, embrace technological innovation and are focused on price and cost management.

Petroleum industry. North American oil prices have been fairly consistent during the past three years despite the significant 
increase in United States oil production from unconventional shale plays.  The growth in North American oil production has been 
offset by reduced oil imports, keeping supply and demand fairly balanced.  Continued oil production growth in United States from 
unconventional  shale  plays  is  expected  to  outpace  the  decline  in  oil  imports  and  increase  oil  price  volatility. The  growth  of 
unconventional  shale  drilling  has  also  substantially  increased  the  supply  of  NGLs,  resulting  in  a  significant  decline  in  NGL 
component prices as the supply of such products has grown. While more export facilities have been built and NGL exports are 
increasing, the overall United States demand for NGL products has not kept pace with the remaining supply of such products; 
consequently, prices for NGL products have generally declined over the past three years. North American gas prices have remained 
volatile and they trended lower from 2009 through 2012, but improved steadily throughout 2013. The decline in North American 
gas prices was primarily a result of significant discoveries of gas and associated gas reserves in United States gas, oil and liquid-
rich shale plays, combined with the warmer than normal recent winters, which resulted in gas storage levels being at historically 

6

 
PIONEER NATURAL RESOURCES COMPANY

high levels, and minimal economic demand growth in the United States.  The increases in gas prices during 2013 were primarily 
related to reduced drilling activity in gas shale plays and demand increases in the latter part of the year as a result of colder weather.

 Oil prices continue to be primarily driven by world supply and demand fundamentals; however, recent increases in United 
States oil, NGL and gas production volumes from the Permian Basin, Eagle Ford, Bakken and Marcellus areas have been met 
with lower demand, higher storage levels and pipeline, gas plant and NGL fractionation infrastructure capacity limitations, which 
has led to a reduction in United States NYMEX oil, NGL and gas prices compared to international prices for similar commodities, 
including Brent oil prices. 

Since  2010,  the  economies  in  the  United  States  and  certain  other  countries  have  continued  to  stabilize  with  resulting 
improvements in industrial demand and consumer confidence. However, other economies, such as those of certain European and 
Asian nations, continue to face economic struggles or slowing economic growth. While the outlook for a continued worldwide 
economic recovery remains cautiously optimistic, it is still uncertain; therefore, the sustainability of the recovery in worldwide 
demand for energy is difficult to predict. As a result, the Company believes it is likely that commodity prices will continue to be 
volatile during 2014.

Significant factors that will affect 2014 commodity prices include: the ongoing effect of economic stimulus initiatives; 
fiscal challenges facing the United States federal government and potential changes to the tax laws in the United States; continuing 
economic struggles in European and Asian nations; political and economic developments in North Africa and the Middle East; 
demand from Asian and European markets; the extent to which members of the Organization of Petroleum Exporting Countries 
("OPEC") and other oil exporting nations are able to manage oil supply through export quotas; the capacity of United States 
refiners to absorb increasing domestic supplies of oil and condensate; potential export regulatory changes in the United States; 
the supply and demand fundamentals for NGLs in the United States and the pace at which export capacity grows; and overall 
North American gas supply and demand fundamentals, including refilling gas storage that is anticipated to be lower than normal 
at the end of the winter draw season.

Pioneer uses commodity derivative contracts to mitigate the effect of commodity price volatility on the Company's net cash 
provided by operating activities and its net asset value. Although the Company has entered into commodity derivative contracts 
for a large portion of its forecasted production through 2015, a sustained lower commodity price environment would result in 
lower realized prices for unprotected volumes and reduce the prices at which the Company could enter into derivative contracts 
on additional volumes in the future. As a result, the Company's internal cash flows would be reduced for affected periods. A 
sustained decline in commodity prices could result in a shortfall in expected cash flows, which could negatively affect the Company's 
liquidity, financial position and future results of operations. See "Item 7A. Quantitative and Qualitative Disclosures About Market 
Risk" and Note E of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary 
Data" for information regarding the Company's open derivative positions as of December 31, 2013.

The Company. The Company's growth plan is primarily anchored by horizontal drilling in the Spraberry/Wolfcamp oil 
field located in West Texas and the liquid-rich Eagle Ford Shale field located in South Texas. Complementing these growth areas, 
the  Company  has  oil  and  gas  production  activities  and  development  opportunities  in  the  Raton  gas  field  located  in  southern 
Colorado, the Hugoton gas and liquid field located in southwest Kansas, the West Panhandle gas and liquid field located in the 
Texas Panhandle and the Edwards gas field located in South Texas. Combined, these assets create a portfolio of resources and 
opportunities that are well balanced and diversified among oil, NGL and gas, and that are also well balanced among long-lived, 
dependable production and lower-risk exploration and development opportunities. The Company has a team of dedicated employees 
who represent the professional disciplines and sciences that the Company believes are necessary to allow Pioneer to maximize 
the long-term profitability and net asset value inherent in its physical assets.

Production. The Company focuses its efforts towards maximizing its average daily production of oil, NGLs and gas through 
development  drilling,  production  enhancement  activities  and  acquisitions  of  producing  properties,  while  minimizing  the 
controllable costs associated with the production activities. For the year ended December 31, 2013, the Company's production 
from continuing operations of 58.9 MMBOE, excluding field fuel usage, represented a 12 percent increase over production from 
continuing operations during 2012. Production, price and cost information with respect to the Company's properties for 2013, 
2012 and 2011 is set forth in "Item 2. Properties — Selected Oil and Gas Information — Production, price and cost data."

Development activities. The Company seeks to increase its proved oil and gas reserves, production and cash flow through 
development drilling and by conducting other production enhancement activities, such as well recompletions. During the three 
years ended December 31, 2013, the Company drilled 1,850 gross (1,655 net) development wells, 99 percent of which were 
successfully completed as productive wells, at a total drilling cost (net to the Company's interest) of $4.8 billion.

The  Company  believes  that  its  current  property  base  provides  a  substantial  inventory  of  prospects  for  future  reserve, 
production and cash flow growth. The Company's proved reserves as of December 31, 2013 include proved undeveloped reserves 
and proved developed reserves that are behind pipe of 102.5 MMBBLs of oil, 41.9 MMBBLs of NGLs and 328.9 BCF of gas. 
7

 
PIONEER NATURAL RESOURCES COMPANY

The Company believes that its proved reserves represent a significant portfolio of development opportunities. The timing of the 
development of these reserves will be dependent upon commodity prices, drilling and operating costs and the Company's expected 
operating cash flows and financial condition.

Exploratory activities. The Company has devoted significant efforts and resources to hiring and developing a highly skilled 
geoscience staff as well as acquiring a significant portfolio of lower-risk exploration opportunities that are expected to be evaluated 
and tested over the next decade and beyond. Exploratory and extension drilling involve greater risks of dry holes or failure to find 
commercial quantities of hydrocarbons than development drilling or enhanced recovery activities. See "Item 1A. Risk Factors — 
Exploration and development drilling may not result in commercially productive reserves" below.

Integrated services.  The Company continues to expand its integrated services to control drilling and operating costs and 
support the execution of its drilling program and operating activities.  The Company has Company-owned fracture stimulation 
fleets totaling approximately 300,000 horsepower supporting drilling operations in the Spraberry/Wolfcamp and Eagle Ford Shale 
areas.  The Company also owns other field service equipment, including pulling units, fracture stimulation tanks, water transport 
trucks, hot oilers, blowout preventers, construction equipment and fishing tools. In April 2012, Pioneer acquired a large U.S. 
industrial sands company, which was renamed Premier Silica (see Note C of Notes to Consolidated Financial Statements included 
in "Item 8. Financial Statements and Supplementary Data" for more information about the acquisition of Premier Silica). That 
acquisition secured a high-quality, low-cost and logistically advantaged brown sand supply for Pioneer to use for its growing 
fracture stimulation requirements in the Spraberry field.

Acquisition  activities.  The  Company  regularly  seeks  to  acquire  properties  that  complement  its  operations,  provide 
exploration and development opportunities and potentially provide superior returns on investment. In addition, the Company 
pursues strategic acquisitions that will allow the Company to expand into new geographical areas that provide future exploration/
exploitation opportunities. During 2013, 2012 and 2011, the Company spent $76.0 million, $157.5 million and $131.9 million, 
respectively, to purchase primarily undeveloped acreage for future exploitation and exploration activities.

In addition, on December 17, 2013, the Company completed the acquisition of all of the outstanding common units of 
Pioneer Southwest not already owned by the Company, through a merger of a wholly-owned subsidiary of the Company into 
Pioneer Southwest, the result of which was that Pioneer Southwest became a wholly-owned subsidiary of the Company. The 
Pioneer Southwest merger was effected pursuant to an Agreement and Plan of Merger dated August 9, 2013, as amended on 
October 25, 2013 (as amended, the "Merger Agreement"), and was approved by the holders of the common units of Pioneer 
Southwest at a special meeting held on December 17, 2013. Pursuant to the Merger Agreement, all of the common units outstanding 
as of the closing of the merger were canceled and converted into the right to receive 0.2325 of a share of common stock of the 
Company per common unit.  In December 2013 the Company issued an aggregate of 3.96 million shares of its common stock to 
Pioneer  Southwest  unitholders. The  merger  is  expected  to  facilitate  the  Company's  plans  to  fully  and  optimally  develop  the 
Company's Spraberry/Wolfcamp properties in the Midland Basin in West Texas utilizing horizontal drilling and is expected to 
enhance the Company's organizational, operational and administrative efficiencies. 

The Company periodically evaluates and pursues acquisition opportunities (including opportunities to acquire particular 
oil and gas assets or entities owning oil and gas assets and opportunities to engage in mergers, consolidations or other business 
combinations with such entities) and at any given time may be in various stages of evaluating such opportunities. Such stages may 
take the form of internal financial analyses, oil and gas reserve analyses, due diligence, the submission of indications of interest, 
preliminary negotiations, negotiation of letters of intent or negotiation of definitive agreements. The success of any acquisition is 
uncertain and depends on a number of factors, some of which are outside the Company's control. See "Item 1A. Risk Factors — 
The Company may be unable to make attractive acquisitions and any acquisition it completes is subject to substantial risks that 
could adversely affect its business."

Asset divestitures and discontinued operations. The Company regularly reviews its asset base for the purpose of identifying 
nonstrategic assets, the disposition of which would increase capital resources available for other activities and create organizational 
and operational efficiencies. While the Company generally does not dispose of assets solely for the purpose of reducing debt, such 
dispositions can have the result of furthering the Company's objective of increasing financial flexibility through reduced debt 
levels.

During the fourth quarter of 2013, the Company committed to a plan to sell 100 percent of the capital stock in Pioneer's 
Alaska subsidiary, representing all the Company's net assets in Alaska ("Pioneer Alaska"). The sale of Pioneer Alaska continues 
to be subject to ongoing negotiations and certain other conditions, such as governmental approvals and buyer's arrangement of 
financing. Associated with the planned sale of Pioneer Alaska, the Company recorded a noncash impairment charge of $539.8 
million during December 2013 to reduce the carrying value of Pioneer Alaska to its estimated fair value less costs to sell of $350.6 
million. The Company has classified Pioneer Alaska assets and liabilities as held for sale in the accompanying consolidated balance

PIONEER NATURAL RESOURCES COMPANY

sheet as of December 31, 2013 and has reported Pioneer Alaska's historical results of operations, and the related impairment loss, 
as discontinued operations, net of tax in the Company's accompanying consolidated statements of operations.

During the fourth quarter of 2013, the Company also committed to a plan to divest of its net assets in the Barnett Shale 
field in North Texas. The plan is expected to result in the sale of the Barnett Shale net assets during 2014.  Associated with the 
plan to sell the Company's net assets in the Barnett Shale field, the Company recorded a noncash impairment charge of $189.5 
million during December 2013 to reduce the carrying value of the Barnett Shale field net assets to their estimated fair value less 
costs to sell. The Company has classified Barnett Shale assets and liabilities as held for sale in the accompanying consolidated 
balance sheet as of December 31, 2013 and has reported Barnett Shale historical results of operations, and the related impairment 
loss, as discontinued operations, net of tax in the Company's accompanying consolidated statements of operations.

During December 2013, the Company committed to a plan to sell its majority interest in Sendero Drilling Company, LLC 
("Sendero"), the Company's vertical drilling rig subsidiary, to Sendero's minority interest owner for $31.0 million, subject to 
negotiating a definitive sales agreement and the buyer completing its financing arrangements.  Associated with the planned sale 
of Sendero, the Company recorded a noncash loss of $25.5 million during December 2013 to reduce the carrying value of Sendero's 
net assets to their estimated fair value. As part of the sales negotiations, the Company plans to commit to lease 12 Sendero rigs 
through December 31, 2015 and to lease eight Sendero rigs in 2016.  The Company has classified Sendero assets and liabilities 
as held for sale in the accompanying consolidated balance sheet as of December 31, 2013.

The Company's plans to sell Pioneer Alaska, the Barnett Shale net assets and Sendero are in various stages of marketing 

or negotiation.  No assurance can be given that the sales will be completed in accordance with the Company's plans. 

In January 2013, the Company signed an agreement with Sinochem Petroleum USA LLC ("Sinochem"), a U.S. subsidiary 
of the Sinochem Group, an unaffiliated third party, to sell 40 percent of Pioneer's interest in 207,000 net acres leased by the 
Company in the horizontal Wolfcamp Shale play in the southern portion of the Spraberry field for consideration of $1.8 billion.  
In May 2013, the Company completed the sale to Sinochem for net cash proceeds of $623.8 million, resulting in a gain of $181.3 
million related to the unproved property interests conveyed to Sinochem.  Sinochem is paying the remaining $1.2 billion of the 
transaction price by carrying 75 percent of Pioneer's portion of ongoing drilling and facilities costs attributable to the Company's 
joint operations with Sinochem in the horizontal Wolfcamp Shale play.  

During December 2011, the Company committed to a plan to exit South Africa and initiated a process to divest its net assets 
in South Africa ("Pioneer South Africa").  During the first quarter of 2012, the Company agreed to sell Pioneer South Africa to 
an unaffiliated third party, effective January 1, 2012, for $60.0 million of cash proceeds before normal closing and other adjustments, 
and the buyer's assumption of certain liabilities of the Company's South Africa subsidiaries. In August 2012, the Company completed 
the sale of Pioneer South Africa for net cash proceeds of $15.9 million, including normal closing adjustments for cash revenues 
and costs and expenses from the effective date through the date of the sale, resulting in a gain of $28.6 million.  The Company 
classified Pioneer South Africa's results of operations as discontinued operations, net of tax in the accompanying consolidated 
statements of operations. 

In February 2011, the Company sold 100 percent of the Company's share holdings in Pioneer Natural Resources Tunisia 
Ltd. and Pioneer Natural Resources Anaguid Ltd. (referred to in the aggregate as "Pioneer Tunisia") to an unaffiliated third party 
for cash proceeds of $802.5 million, excluding cash and cash equivalents sold, resulting in a gain of $645.2 million.  The Company 
classified the results of operations of Pioneer Tunisia as discontinued operations, net of tax in the accompanying consolidated 
statements of operations.

The Company anticipates that it will continue to sell nonstrategic properties or other assets from time to time to increase 
capital resources available for other activities, to achieve operating and administrative efficiencies and to improve profitability. 
See Note C of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" 
for specific information regarding the Company's asset divestitures and discontinued operations.  Also see "Item1A. Risk Factors 
- The Company's ability to complete dispositions of assets, or interests in assets, may be subject to factors beyond its control, and 
in certain cases the Company may be required to retain liabilities for certain matters" for discussion of risk factors associated with 
the completion of divestitures.

Marketing of Production

General. Production from the Company's properties is marketed using methods that are consistent with industry practices. 
Sales prices for oil, NGL and gas production are negotiated based on factors normally considered in the industry, such as an index 
or spot price, price regulations, distance from the well to the pipeline, commodity quality and prevailing supply and demand 
conditions. See "Item 7A. Quantitative and Qualitative Disclosures About Market Risk" for additional discussion of operations 
and price risk.

PIONEER NATURAL RESOURCES COMPANY

Significant purchasers. During 2013, the Company's significant purchasers of oil, NGLs and gas were Plains Marketing 
LP (26 percent), Enterprise Products Partners L.P. (12 percent) and Occidental Energy Marketing Inc. (12 percent). The Company 
believes  that  the  loss  of  a  significant  purchaser  or  an  inability  to  secure  adequate  pipeline,  gas  plant  and  NGL  fractionation 
infrastructure in its key producing areas could have a material adverse effect on its ability to sell its oil, NGL and gas production. 
See "Item 1A. Risk Factors" and Note L of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements 
and Supplementary Data" for more information about significant customer and infrastructure capacity risks.

Derivative risk management activities. The Company primarily utilizes commodity swap contracts, collar contracts and 
collar contracts with short puts to (i) reduce the effect of price volatility on the commodities the Company produces and sells or 
consumes,  (ii) support  the  Company's  annual  capital  budgeting  and  expenditure  plans  and  (iii) reduce  commodity  price  risk 
associated with certain capital projects. The Company also, from time to time, utilizes interest rate contracts to reduce the effect 
of interest rate volatility on the Company's indebtedness. The Company accounts for its derivative contracts using the mark-to-
market ("MTM") method of accounting. See "Item 7. Management's Discussion and Analysis of Financial Condition and Results 
of Operations" for a description of the Company's derivative risk management activities, "Item 7A. Quantitative and Qualitative 
Disclosures About  Market  Risk,"  and  Note  E  of  Notes  to  Consolidated  Financial  Statements  included  in  "Item  8.  Financial 
Statements and Supplementary Data" for information about the impact of commodity derivative activities on oil, NGL and gas 
revenues and net derivative gains and losses during 2013, 2012 and 2011, as well as the Company's open commodity derivative 
positions at December 31, 2013.

Competition, Markets and Regulations

Competition. The oil and gas industry is highly competitive. A large number of companies, including major integrated and 
other independent companies, and individuals engage in the exploration for and development of oil and gas properties, and there 
is a high degree of competition for oil and gas properties suitable for development or exploration. Acquisitions of oil and gas 
properties have been an important element of the Company's growth. The Company intends to continue acquiring oil and gas 
properties that complement its operations, provide exploration and development opportunities and potentially provide superior 
returns on investment. The principal competitive factors in the acquisition of oil and gas properties include the staff and data 
necessary  to  identify,  evaluate  and  acquire  such  properties  and  the  financial  resources  necessary  to  acquire  and  develop  the 
properties. Some of the Company's competitors are substantially larger and have financial and other resources greater than those 
of the Company.

Markets. The Company's ability to produce and market oil, NGLs and gas profitably depends on numerous factors beyond 
the Company's control.  The effect of these factors cannot be accurately predicted or anticipated. Although the Company cannot 
predict the occurrence of events that may affect these commodity prices or the degree to which these prices will be affected, the 
prices for any commodity that the Company produces will generally approximate current market prices in the geographic region 
of the production.

Securities regulations. Enterprises that sell securities in public markets are subject to regulatory oversight by agencies such 
as the SEC and the NYSE. This regulatory oversight imposes on the Company the responsibility for establishing and maintaining 
disclosure controls and procedures and internal controls over financial reporting, and ensuring that the financial statements and 
other information included in submissions to the SEC do not contain any untrue statement of a material fact or omit to state a 
material fact necessary to make the statements made in such submissions not misleading. Failure to comply with the rules and 
regulations of the SEC could subject the Company to litigation from public or private plaintiffs. Failure to comply with the rules 
of the NYSE could result in the de-listing of the Company's common stock, which would have an adverse effect on the market 
price and liquidity of the Company's common stock. Compliance with some of these rules and regulations is costly, and regulations 
are subject to change or reinterpretation.

 Environmental and occupational health and safety matters. The Company's operations are subject to stringent and complex 
federal, state and local laws and regulations governing environmental protection, worker health and safety, and the discharge of 
materials into the environment. Numerous governmental entities, including the U.S. Environmental Protection Agency (the "EPA") 
and analogous state agencies have the power to enforce compliance with these laws and regulations and the permits issued under 
them,  often  requiring  difficult  and  costly  actions  to  achieve  and  maintain  compliance  and  imposing  sanctions,  including 
administrative, civil and criminal penalties, for any failure to comply.

These laws and regulations may, among other things:

• 
• 
• 

require the acquisition of various permits before drilling or other regulated activity commences;
enjoin some or all of the operations of facilities deemed in noncompliance with permits;
restrict  the  types,  quantities  and  concentration  of  various  substances  that  can  be  released  into  the  environment  in 
connection with oil and gas drilling, production and transportation activities;

10

PIONEER NATURAL RESOURCES COMPANY

• 
• 
• 

• 

limit or prohibit drilling activities on certain lands lying within wilderness, wetlands and other protected areas;
impose specific criteria addressing worker protection;
require remedial measures to mitigate pollution from former and ongoing operations, such as requirements to close 
pits and plug abandoned wells; and
impose substantial liabilities for pollution resulting from operations.

These laws and regulations may also restrict the rate of oil and gas production below the rate that would otherwise be 
possible. The regulatory burden on the oil and gas industry increases the cost of doing business in the industry and consequently 
affects profitability. Additionally, the U.S. Congress, state legislatures and federal and state regulatory agencies frequently revise 
environmental laws and regulations, and the trend in environmental regulation is to place more restrictions and limitations on 
activities that may affect the environment. Any changes that result in more stringent and costly drilling, completion, construction 
or water management activities, or waste handling, disposal and cleanup requirements for the oil and gas industry could have a 
significant effect on the Company's capital and operating costs.

The following is a summary of some of the more significant laws and regulations to which the Company's business operations 

are or may be subject.

Waste handling. The federal 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. Under the auspices 
of 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 gas are currently regulated under RCRA's non-hazardous waste provisions. It is possible 
that certain oil and gas exploration and production wastes now classified as non-hazardous could be classified as hazardous wastes 
in the future. Any such change could result in an increase in the Company's costs to manage and dispose of wastes, which could 
have a material adverse effect on the Company's results of operations and financial position. In the course of its operations, the 
Company generates some amounts of ordinary industrial wastes, such as paint wastes, waste solvents and waste oils that may be 
regulated as hazardous wastes.

Wastes  containing  naturally  occurring  radioactive  materials  ("NORM")  may  also  be  generated  in  connection  with  the 
Company's operations. NORM is subject primarily to individual state radiation control regulations. In addition, NORM handling 
and  management  activities  are  governed  by  regulations  promulgated  by  the  Occupational  Safety  and  Health Administration 
("OSHA"). These state and OSHA regulations impose certain requirements concerning worker protection, with respect to NORM, 
the treatment, storage and disposal of NORM waste, the management of waste piles, containers and tanks containing NORM and 
restrictions on the uses of land with NORM contamination.

Comprehensive Environmental Response, Compensation, and Liability Act. The federal Comprehensive Environmental 
Response, Compensation and Liability Act ("CERCLA"), also known as the Superfund law, and analogous state laws impose 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 and past 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 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. CERCLA 
also authorizes the EPA and, in some instances, third parties to act in response to threats to the public health or the environment 
and to seek to recover from the responsible classes of persons the costs they incur. 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.

The Company currently owns or leases numerous properties that have been used for oil and gas exploration and production 
for many years. Although the Company believes it has used operating and waste disposal practices that were standard in the 
industry at the time, hazardous substances, wastes or petroleum hydrocarbons may have been released on or under the properties 
owned or leased by the Company, or on or under other locations, including off-site locations, where such substances have been 
taken for recycling or disposal. In addition, some of the Company's properties have been operated by previous owners or operators 
whose treatment and disposal of hazardous substances, wastes or petroleum hydrocarbons were not under the Company's control. 
Certain of these properties have had historical petroleum spills or releases. All of such properties and the substances disposed or 
released on them may be subject to CERCLA, RCRA and analogous state laws. Under such laws, the Company could be required 
to remove previously disposed substances and wastes, remediate contaminated property or perform remedial plugging or pit closure 
operations to prevent future contamination. If a surface spill or release were to occur, the Company expects that it would be 
controlled, contained and remediated in accordance with the applicable requirements of state oil and gas commissions and by 
using the Company's spill prevention, control and countermeasure ("SPCC") plans or other spill or emergency contingency plans 
that it maintains in accordance with EPA requirements.

Water discharges and use. The federal Water Pollution Control Act, also known as the Clean Water Act (the "CWA"), 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 and state waters. The discharge of pollutants into regulated waters is 
prohibited, except in accordance with the terms of a permit issued by the EPA or an analogous state agency. The CWA and regulations 
implemented thereunder also prohibit the discharge of dredge and fill material into regulated waters, including wetlands, unless 
authorized by an appropriately issued permit. SPCC planning requirements of federal laws require appropriate containment berms 
and similar structures to help prevent the contamination of navigable waters by a petroleum hydrocarbon tank spill, rupture or 
leak. Federal and state regulatory agencies can impose administrative, civil and criminal penalties for noncompliance with discharge 
permits or other requirements of the CWA and analogous state laws and regulations.

The primary federal law imposing liability for oil spills is the Oil Pollution Act ("OPA"), which sets minimum standards 
for prevention, containment and cleanup of oil spills. OPA applies to vessels, offshore facilities and onshore facilities, including 
exploration and production facilities that may affect waters of the United States. Under OPA, responsible parties, including owners 
and operators of onshore facilities, may be subject to oil spill cleanup costs and natural resource damages as well as a variety of 
public and private damages that may result from oil spills. If an oil spill subject to the requirements of OPA were to occur at a 
Company property, the Company expects that it would be controlled, contained and remediated in accordance with the applicable 
requirements of OPA and by using the Company's OPA spill response plan together with the assistance of trained first responders 
and any oil spill response contractor that the Company would have engaged pursuant to OPA to address such oil spills.

Operations associated with the Company's properties also produce wastewaters that are disposed by injection in underground 
wells. These injection wells are regulated by the federal Safe Drinking Water Act (the "SDWA") and analogous state and local 
laws. The underground injection well program under the SDWA requires permits from the EPA or analogous state agency for the 
Company's disposal wells, establishes minimum standards for injection well operations, and restricts the types and quantities of 
fluids that may be injected. Currently, the Company believes that disposal well operations on the Company's properties substantially 
comply with all applicable requirements under the SDWA. However, a change in the regulations or the inability to obtain permits 
for new injection wells in the future may affect the Company's ability to dispose of produced waters and ultimately increase the 
cost of the Company's operations. For example, in some areas of Texas, there has been concern that certain formations into which 
disposal wells are injecting produced waters could become over-pressured after many years of injection, and the governing Texas 
regulatory agency is reviewing the data to determine whether any action is necessary to address this issue. If the Texas state agency 
were to decline to issue permits for new injection wells into the formations currently utilized by the Company, the Company may 
be required to seek alternative methods of disposing of produced waters, including injecting into deeper formations, which could 
increase its costs. In addition, in response to recent seismic events near underground injection wells used for the disposal of 
wastewaters, some federal and state agencies have been investigating whether such wells have caused increased seismic activity. 
It is possible that federal or state agencies will seek to regulate more stringently the underground injection of oil and gas wastewaters 
as a result of these events. Nevertheless, the Company is not aware of any imminent actions by federal or state agencies that would 
affect its use or operation of underground injection wells due to the concern about seismic activity.

The  Company  also  uses  hydraulic  fracturing  techniques  in  virtually  all  of  its  drilling  and  completion  programs  and 
development of its properties is dependent on the Company's ability to hydraulically fracture the producing formations. The process 
involves the injection of water, sand and additives under pressure into targeted subsurface formations to stimulate oil and gas 
production. The process is typically regulated by state oil and gas commissions, but, the EPA has asserted federal regulatory 
authority over hydraulic fracturing involving diesel fuels under the SDWA Underground Injection Control Program and published 
final permitting guidance in February 2014 addressing the performance of such activities. In 2011, the EPA announced its intent 
to develop and issue regulations under the Toxic Substances Control Act to require companies to disclose information regarding 
the chemicals used in hydraulic fracturing, and in its Semi-annual Regulatory Agenda published in July 2013, the agency continues 
to project the future issuance of an Advance Notice of Proposed Rulemaking that would seek public input on the design and scope 
of such disclosure regulations. The EPA published final rules under the federal Clean Air Act ("CAA") that, among other things, 
require producers to reduce volatile organic compound emissions from certain subcategories of fractured and refractured gas wells 
for which well completion operations are being conducted by routing flowback emissions to a gathering line or capturing and 
combusting flowback emissions using a combustion device, such as a flare, until January 1, 2015 and performing reduced emission 
completions, also known as "green completions," with or without combustion devices, on or after January 1, 2015.  Also, in May 
2013, the federal Bureau of Land Management (the "BLM") published a supplemental notice of proposed rulemaking governing 
hydraulic fracturing on federal and Indian oil and gas leases that would require public disclosure of chemicals used in hydraulic 
fracturing, confirmation that wells used in fracturing operations meet appropriate construction standards, and development of 
appropriate plans for managing flowback water that returns to the surface. In addition, the U.S. Congress, from time to time, has 
considered adopting legislation intended to provide for federal regulation of hydraulic fracturing and to require disclosure of the 
chemicals used in the hydraulic-fracturing process.

Certain states in which the Company operates, including Colorado and Texas, have adopted, and other states are considering 
adopting,  regulations  that  could  impose  new  or  more  stringent  permitting,  disclosure  and  well-construction  requirements  on 
12

PIONEER NATURAL RESOURCES COMPANY

hydraulic fracturing operations.  In addition to state laws, local land use restrictions, such as city ordinances, may restrict or prohibit 
drilling in general or hydraulic fracturing in particular. The Company believes that it follows applicable standard industry practices 
and legal requirements for groundwater protection in its hydraulic fracturing activities. Nonetheless, in the event federal, state or 
local restrictions are adopted in areas where the Company is currently conducting, or in the future plans to conduct operations, 
the Company may incur additional costs to comply with such requirements that may be significant in nature, experience delays 
or curtailment in the pursuit of exploration, development or production activities, and be limited or precluded in the drilling of 
wells or in the amounts that the Company is ultimately able to produce from its reserves. 

Certain governmental reviews were recently conducted or are underway that focus on environmental aspects of hydraulic 
fracturing  practices.  The  White  House  Council  on  Environmental  Quality  is  coordinating  an  administration-wide  review  of 
hydraulic fracturing practices. The EPA has commenced a study of the potential environmental effects of hydraulic fracturing on 
drinking water and groundwater and a draft report is expected to be available for public comments and peer review in 2014. 
Moreover,  the  EPA  is  developing  effluent  limitations  for  the  treatment  and  discharge  of  wastewater  resulting  from  hydraulic 
fracturing activities and is expected to propose these standards in 2014. These studies, or future studies, depending on their degree 
of pursuit and any meaningful results obtained, could spur initiatives to further regulate hydraulic fracturing under the SDWA or 
other regulatory mechanisms.

The water produced by the Company's CBM operations also may be subject to the state laws and regulations of regulatory 
bodies regarding the ownership and use of water. For example, in connection with the Company's CBM operations in the Raton 
Basin in Colorado, water is removed from coal seams to reduce pressure and allow the methane to be recovered. Historically, 
these operations have been regulated by the state agency responsible for regulating oil and gas activity in the state. Nevertheless,  
in 2009, the Colorado Supreme Court affirmed a state court holding that water produced in connection with the CBM operations 
should be subject to state water-use regulations administered by a different agency that regulates other uses of water in the state, 
including requirements to obtain permits for diversion and use of surface and subsurface water, an evaluation of potential competing 
uses of the water, and a possible requirement to provide mitigation water for other water users. The Colorado legislature and state 
agency adopted laws  and regulations in  response  to this  ruling. These  and  other  resulting changes  in  the  regulation  of water 
produced from CBM operations may have an adverse effect on the costs of doing business and the ability to expand operations 
by the Company or other CBM producers.

Air  emissions. The  CAA  and  comparable  state  laws  regulate  emissions  of  various  air  pollutants  through  air  emissions 
permitting programs and the imposition of other requirements. Such laws and regulations may require a facility to obtain pre-
approval for the construction or modification of certain projects or facilities expected to produce air emissions or result in the 
increase  of  existing  air  emissions;  obtain  or  strictly  comply  with  air  permits  containing  various  emissions  and  operational 
limitations; or utilize specific emission control technologies to limit emissions of certain air pollutants. In addition, the EPA has 
developed,  and  continues  to  develop,  stringent  regulations  governing  emissions  of  toxic  air  pollutants  at  specified  sources. 
Moreover, states may impose their own air emissions limitations, which may be more stringent than the federal standards imposed 
by the EPA.  Federal and state regulatory agencies can also impose administrative, civil and criminal penalties for noncompliance 
with air permits or other requirements of the CAA and associated state laws and regulations. The adoption of laws, regulations, 
orders or other legally enforceable mandates governing oil and gas drilling and operating activities in the areas where the Company 
conducts business that result in more stringent drilling or operating conditions or limit or prohibit the drilling of new wells for 
any extended period of time could increase the Company's costs or reduce its production, which could have a material adverse 
effect on the Company's results of operations and cash flows.

Permits and related compliance obligations under the CAA, as well as changes to state implementation plans for controlling 
air emissions in regional non-attainment areas, may require the Company to incur future capital expenditures in connection with 
the addition or modification of existing air emission control equipment and strategies for oil and gas exploration and production 
operations. For example, in 2012, the EPA published final rules under the CAA that subject oil and gas production, processing, 
transmission and storage operations to regulation under the New Source Performance Standards and National Emission Standards 
for Hazardous Air Pollutants programs. With regard to production activities, these final rules require, among other things, the 
reduction of volatile organic compound emissions from three subcategories of fractured and refractured gas wells for which well 
completion operations are conducted: wildcat (exploratory) and delineation gas wells; low reservoir pressure non-wildcat and 
non-delineation gas wells; and all "other" fractured and refractured gas wells.  All three subcategories of wells must route flowback 
emissions to a gathering line or capture and combust flowback emissions using a combustion device, such as a flare.  However, 
the "other" wells must use reduced emission completions, also known as "green completions," with or without combustion devices, 
on or after January 1, 2015.  These regulations also establish specific new requirements regarding emissions from production-
related wet seal and reciprocating compressors, effective October 15, 2012 and from pneumatic controllers and storage vessels, 
beginning as early as October 15, 2013.  Compliance with these requirements could increase the Company's costs of development 
and production, which costs could be significant. 

13

PIONEER NATURAL RESOURCES COMPANY

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 the Company's operations are conducted in areas where 
protected species or their habitats are known to exist. In these areas, the Company may be obligated to develop and implement 
plans to avoid potential adverse effects to protected species and their habitats, and the Company may be prohibited from conducting 
operations in certain locations or during certain seasons, such as breeding and nesting seasons, when the Company's 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 the Company performs activities could result in increased costs or limitations on 
the Company's ability to perform operations and thus have an adverse effect on the Company's business.

Moreover, as a result of a settlement approved by the U.S. District Court for the District of Columbia in September 2011, 
the U.S. Fish and Wildlife Service is required to make a determination on the potential listing of numerous species as endangered 
or threatened under the ESA before completion of the agency's 2017 fiscal year. The designation of previously unprotected species 
as threatened or endangered in areas where the Company operates could cause the Company to incur increased costs arising from 
species protection measures or could result in limitations on the Company's drilling and production activities that could have an 
adverse effect on the Company's ability to develop and produce its proved reserves.

Activities on Federal Lands.  Oil and gas exploration, development and production activities on federal lands, including 
Indian lands and lands administered by the BLM, are subject to the National Environmental Policy Act, as amended ("NEPA").  
NEPA requires federal agencies, including the BLM, 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.  Currently, the Company has minimal exploration and 
production activities on federal lands. However, for those current activities as well as for future or proposed exploration and 
development plans on federal lands, governmental permits or authorizations that are subject to the requirements of NEPA are 
required.  This  process  has  the  potential  to  delay  or  limit,  or  increase  the  cost  of,  the  development  of  oil  and  gas  projects.  
Authorizations under NEPA are also subject to protest, appeal or litigation, any or all of which may delay or halt projects.

Occupational health and safety. The Company's operations are subject to the requirements of OSHA and comparable state 
statutes. These laws and the related regulations strictly govern the protection of the health and safety of employees. The OSHA 
hazard communication standard, EPA community right-to-know regulations under Title III of CERCLA and similar state statues 
require that the Company organize or disclose information about hazardous materials used or produced in the Company's operations. 
In addition, the Company's sand mining operations are subject to the Federal Mine Safety and Health Act of 1977, as amended 
by the Mine Improvement and New Emergency Response Act of 2006, which imposes stringent health and safety standards on 
numerous aspects of mineral extraction and processing operations, including the training of personnel, operating procedures, 
operating equipment and other matters.  The Company believes that it is in substantial compliance with these applicable standards 
and with OSHA and comparable requirements.

Climate change. In 2009, the EPA published its findings that emissions of carbon dioxide, methane and other greenhouse 
gases ("GHGs") present an endangerment to public health and the environment because emissions of such gases are, according 
to the EPA, contributing to warming of the Earth's atmosphere and other climatic changes.  Based on these findings, the EPA has 
adopted  regulations  under  the  CAA  establishing  Title  V  and  Prevention  of  Significant  Deterioration  ("PSD")  permitting 
requirements for large sources of GHGs. The Company could become subject to these permitting requirements and be required 
to install "best available control technology" to limit emissions of GHGs from any new or significantly modified facilities that the 
Company may seek to construct in the future if they would otherwise emit large volumes of GHGs. The EPA has also adopted 
rules requiring the reporting of GHG emissions on an annual basis from specified GHG emission sources in the United States, 
including certain oil and gas production facilities, which includes certain of the Company's facilities. The Company is monitoring 
GHG emissions from its operations in accordance with these GHG emissions reporting rules and believes its monitoring activities 
are in substantial compliance with applicable reporting obligations.

While the U.S. 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 GHG emissions at the federal level in recent years. In the absence 
of federal climate legislation in the United States, a number of state and regional efforts have emerged that are aimed at tracking 
or reducing GHG emissions by means of cap and trade programs that typically require major sources of GHG emissions, such as 
electric power plants, to acquire and surrender emission allowances in return for emitting those GHGs.  If the U.S. Congress 
undertakes comprehensive tax reform in the coming year, it is possible that such reform may include a carbon tax, which could 
impose additional direct costs on the Company's operations.

Although it is not possible at this time to predict how legislation or new regulations that may be adopted to address GHG 
emissions would affect the Company's business, any such future laws and regulations could require the Company to incur increased 

14

PIONEER NATURAL RESOURCES COMPANY

operating costs, such as costs to purchase and operate emissions control systems, acquire emissions allowances or comply with 
new regulatory or reporting requirements including the imposition of a carbon tax. Any such legislation or regulatory programs 
could also increase the cost to the consumer, and thereby reduce demand for oil and gas, which could reduce the demand for the 
oil and gas the Company produces. Consequently, legislation and regulatory programs to reduce emissions of GHGs could have 
an adverse effect on the Company's business, financial condition and results of operations. 

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, floods and other 
climatic events. If any such effects were to occur, they could have an adverse effect on the Company's financial condition and 
results of operations.

Other regulation of the oil and gas industry. The oil and gas industry is regulated by numerous federal, state and local 
authorities. Legislation affecting the oil and gas industry is under constant review for amendment or expansion, frequently increasing 
the regulatory burden. Also, numerous federal and state departments and agencies are authorized by statute to issue rules and 
regulations binding on the oil and gas industry and its individual members, some of which carry substantial penalties for failure 
to comply. Although the regulatory burden on the oil and gas industry may increase the Company's cost of doing business by 
increasing the cost of production, the Company believes that these burdens generally do not affect the Company any differently 
or to any greater or lesser extent than they affect other companies in the industry with similar types, quantities and locations of 
production.

Development and production. Development and production operations are subject to various types of regulation at federal, 
state and local levels. These types of regulation include requiring permits for the drilling of wells, the posting of bonds in connection 
with various types of activities and filing reports concerning operations. Most states, and some counties and municipalities, in 
which the Company operates also regulate one or more of the following:

• 
• 
• 
• 
• 
• 

the location of wells;
the method of drilling and casing wells;
the method and ability to fracture stimulate wells;
the surface use and restoration of properties upon which wells are drilled;
the plugging and abandoning of wells; and
notice to surface owners and other third parties.

State laws regulate the size and shape of drilling and spacing units or proration units governing the pooling of oil and gas 
properties. Some states allow forced pooling or integration of tracts to facilitate development while other states rely on voluntary 
pooling of lands and leases. In some instances, forced pooling or unitization may be implemented by third parties and may reduce 
the Company's interest in the unitized properties. In addition, state conservation laws establish maximum rates of production from 
oil and gas wells, generally prohibit the venting or flaring of gas and impose requirements regarding the ratability of production. 
These laws and regulations may limit the amount of oil and gas the Company can produce from the Company's wells or limit the 
number of wells or the locations at which the Company can drill. Moreover, each state generally imposes a production or severance 
tax with respect to the production and sale of oil, NGL and gas within its jurisdiction. States do not regulate wellhead prices or 
engage in other similar direct regulation, but there can be no assurance that they will not do so in the future. The effect of such 
future regulations may be to limit the amounts of oil and gas that may be produced from the Company's wells, negatively affect 
the economics of production from these wells, or limit the number of locations the Company can drill.

Regulation of transportation and sale of gas. The availability, terms and cost of transportation significantly affect sales of 
gas. Federal and state regulations govern the price and terms for access to gas pipeline transportation. Intrastate gas pipeline 
transportation activities are subject to various state laws and regulations, as well as orders of state regulatory bodies. The interstate 
transportation and sale of gas is subject to federal regulation, including regulation of the terms, conditions and rates for interstate 
transportation, storage and various other matters, primarily by the Federal Energy Regulatory Commission ("FERC"). FERC 
endeavors to make gas transportation more accessible to gas buyers and sellers on an open-access and non-discriminatory basis.

Pursuant to the Energy Policy Act of 2005 ("EPAct 2005") it is unlawful for "any entity," including producers such as the 
Company, that are otherwise not subject to FERC's jurisdiction under the Natural Gas Act (the "NGA"), to use any deceptive or 
manipulative device or contrivance in connection with the purchase or sale of gas or the purchase or sale of transportation services 
subject to regulation by FERC, in contravention of rules prescribed by FERC. FERC's rules implementing this provision make it 
unlawful, in connection with the purchase or sale of gas subject to the jurisdiction of FERC, or the purchase or sale of transportation 
services subject to the jurisdiction of FERC, for any entity, directly or indirectly, to use or employ any device, scheme or artifice 
to defraud; to make any untrue statement of material fact or omit to make any such statement necessary to make the statements 
made not misleading; or to engage in any act or practice that operates as a fraud or deceit upon any person. EPAct 2005 also gives 
FERC authority to impose civil penalties of up to $1.0 million per day for each violation of the NGA or the Natural Gas Policy 

15

PIONEER NATURAL RESOURCES COMPANY

Act of 1978. The anti-manipulation rule applies to activities of entities not otherwise subject to FERC's jurisdiction to the extent 
the activities are conducted "in connection with" gas sales, purchases or transportation subject to FERC jurisdiction, which includes 
the annual reporting requirements under Order 704 (defined below).

In December 2007, FERC issued a final rule on the annual gas transaction reporting requirements, as amended by subsequent 
orders on rehearing ("Order 704"). Under Order 704, any market participant, including a producer such as the Company, that 
engages in wholesale sales or purchases of gas that equal or exceed 2.2 million MMBTUs of physical gas in the previous calendar 
year must annually report such sales and purchases to FERC on Form No. 552 on May 1 of each year. Form No. 552 contains 
aggregate volumes of gas purchased or sold at wholesale in the prior calendar year to the extent such transactions utilize, contribute 
to or may contribute to the formation of price indices.  It is the responsibility of the reporting entity to determine which individual 
transactions should be reported based on the guidance of Order 704. Order 704 is intended to increase the transparency of the 
wholesale gas markets and to assist FERC in monitoring those markets and in detecting market manipulation.

Additional  proposals  and  proceedings  that  might  affect  the  gas  industry  are  considered  from  time  to  time  by  the  U.S. 
Congress, FERC, state regulatory bodies and the courts.  The Company cannot predict when or if any such proposals might become 
effective or their effect, if any, on its operations.  The Company does not believe that it will be affected by any action taken in a 
materially different way than other gas producers, gatherers and marketers with which it competes.

Natural gas processing.  The Company's gas processing operations are not subject to FERC or state regulation.  There can 
be no assurance that the Company's processing operations will continue to be exempt from regulation in the future.  However, 
although the processing facilities may not be directly related, other laws and regulations may affect the availability of gas for 
processing, such as state regulation of production rates and maximum daily production allowable from gas wells, which could 
impact the Company's processing business.  

Gas gathering. Section 1(b) of the NGA exempts gas gathering facilities from FERC's jurisdiction. The Company believes 
that its gathering facilities meet the traditional tests FERC has used to establish a pipeline system's status as a non-jurisdictional 
gatherer.  There  is,  however,  no  bright-line  test  for  determining  the  jurisdictional  status  of  pipeline  facilities.  Moreover,  the 
distinction between FERC-regulated transmission services and federally unregulated gathering services is the subject of litigation 
from time to time, so the classification and regulation of some of the Company's gathering facilities may be subject to change 
based on future determinations by FERC and the courts. Thus, the Company cannot guarantee that the jurisdictional status of its 
gas gathering facilities will remain unchanged.

While the Company owns or operates some gas gathering facilities, the Company also depends on gathering facilities owned 
and operated by third parties to gather production from its properties, and therefore the Company is affected by the rates charged 
by these third parties for gathering services. To the extent that changes in federal or state regulation affect the rates charged for 
gathering services, the Company also may be affected by these changes. Accordingly, the Company does not anticipate that the 
Company would be affected any differently than similarly situated gas producers.

Regulation of transportation and sale of oil and NGLs. The liquids industry is also extensively regulated by numerous 
federal, state and local authorities. In a number of instances, the ability to transport and sell such products on interstate pipelines 
is  dependent  on  pipelines  whose  rates,  terms  and  conditions  of  service  are  subject  to  FERC  jurisdiction  under  the  Interstate 
Commerce Act (the "ICA").  The Company does not believe these regulations affect it any differently than other producers.

The ICA requires that pipelines maintain a tariff on file with FERC. The tariff sets forth the established rates as well as the 
rules and regulations governing the service.  The ICA requires, among other things, that rates and terms and conditions of service 
on interstate common carrier pipelines be "just and reasonable."  Such pipelines must also provide jurisdictional service in a manner 
that is not unduly discriminatory or unduly preferential.  Shippers have the power to challenge new and existing rates and terms 
and conditions of service before FERC.

Rates of interstate liquids pipelines are currently regulated by FERC primarily through an annual indexing methodology, 
under which pipelines increase or decrease their rates in accordance with an index adjustment specified by FERC.  For the five-
year period beginning in 2010, FERC established an annual index adjustment equal to the change in the producer price index for 
finished goods plus 2.65 percent.  This adjustment is subject to review every five years.  Under FERC's regulations, a liquids 
pipeline can request a rate increase that exceeds the rate obtained through application of the indexing methodology by using a 
cost-of-service  approach,  but  only  after  the  pipeline  establishes  that  a  substantial  divergence  exists  between  the  actual  costs 
experienced by the pipeline and the rates resulting from application of the indexing methodology.  Increases in liquids transportation 
rates may result in lower revenue and cash flows for the Company. 

In addition, due to common carrier regulatory obligations of liquids pipelines, capacity must be prorated among shippers 
in an equitable manner in the event there are nominations in excess of capacity by current shippers or capacity requests are received 
from a new shipper.  Therefore, new shippers or increased volume by existing shippers may reduce the capacity available to the 

16

PIONEER NATURAL RESOURCES COMPANY

Company. Any prolonged interruption in the operation or curtailment of available capacity of the pipelines that the Company relies 
upon for liquids transportation could have a material adverse effect on its business, financial condition, results of operations and 
cash flows.  However, the Company believes that access to liquids pipeline transportation services generally will be available to 
it to the same extent as to its similarly-situated competitors.

Intrastate liquids pipeline transportation rates are subject to regulation by state regulatory commissions.  The basis for 
intrastate liquids pipeline regulation, and the degree of regulatory oversight and scrutiny given to intrastate liquids pipeline rates, 
varies from state to state.  The Company believes that the regulation of liquids pipeline transportation rates will not affect its 
operations in any way that is materially different from the effects on its similarly-situated competitors.

In November 2009, the Federal Trade Commission ("FTC") issued regulations pursuant to the Energy Independence and 
Security Act of 2007 intended to prohibit market manipulation in the petroleum industry.  Violators of the regulations face civil 
penalties of up to $1.0 million per violation per day.  In July 2010, the U.S. Congress passed the Dodd-Frank Wall Street Reform 
and Consumer Protection Act, which incorporated an expansion of the authority of the Commodity Futures Trading Commission 
("CFTC") to prohibit market manipulation in the markets regulated by the CFTC. This authority, with respect to oil swaps and 
futures contracts, is similar to the anti-manipulation authority granted to the FERC with respect to anti-manipulation in the gas 
industry and the FTC with respect to oil purchases and sales, as described above.  In July 2011, the CFTC issued final rules to 
implement their new anti-manipulation authority.  The rules subject violators to a civil penalty of up to the greater of $1.0 million 
or triple the monetary gain to the person for each violation.

Energy commodity prices. Sales prices of oil, condensate, NGLs and gas are not currently regulated and are made at market 
prices. Although prices of these energy commodities are currently unregulated, the U.S. Congress historically has been active in 
their regulation. The Company cannot predict whether new legislation to regulate oil and gas might actually be enacted by the 
U.S. Congress or the various state legislatures, and what effect, if any, the proposals might have on the Company's operations.

Transportation of hazardous materials. The federal Department of Transportation has adopted regulations requiring that 
certain entities transporting designated hazardous materials develop plans to address security risks related to the transportation of 
hazardous materials. The Company does not believe that these requirements will have an adverse effect on the Company or its 
operations. The Company cannot provide any assurance that the security plans required under these regulations would protect 
against all security risks and prevent an attack or other incident related to the Company's transportation of hazardous materials.

ITEM 1A. RISK FACTORS

The nature of the business activities conducted by the Company subjects it to certain hazards and risks. The following is a 
summary of some of the material risks relating to the Company's business activities. Other risks are described in "Item 1. Business 
— Competition, Markets and Regulations," "Item 7. Management's Discussion and Analysis of Financial Condition and Results 
of Operations" and "Item 7A. Quantitative and Qualitative Disclosures About Market Risk." These risks are not the only risks 
facing the Company. The Company's business could also be affected by additional risks and uncertainties not currently known to 
the Company or that it currently deems to be immaterial. If any of these risks actually occurs, it could materially harm the Company's 
business, financial condition or results of operations and impair the Company's ability to implement business plans or complete 
development activities as scheduled. In that case, the market price of the Company's common stock could decline.

The prices of oil, NGL and gas are highly volatile. A sustained decline in these commodity prices could adversely affect the 
Company's financial condition and results of operations.

The Company's revenues, profitability, cash flow and future rate of growth are highly dependent on commodity prices. 
Commodity prices may fluctuate widely in response to relatively minor changes in the supply of and demand for oil, NGL and 
gas, market uncertainty and a variety of additional factors that are beyond the Company's control, such as:

domestic and worldwide supply of and demand for oil, NGL and gas;
inventory levels at Cushing, Oklahoma, the benchmark for WTI oil prices;
oil, NGL and gas inventory levels in the United States;
the capacity of U.S. refiners to absorb increasing domestic supplies of oil and condensate; 

• 
• 
• 
• 
•  weather conditions;
• 

overall domestic and global political and economic conditions, including laws, regulations and administrative policies 
that restrict the export of the Company's products;
actions of OPEC, its members and other state-controlled oil companies relating to oil price and production controls;
the effect of liquefied natural gas deliveries to and exports from the United States;
technological advances affecting energy consumption and energy supply;
domestic and foreign governmental regulations and taxation;

• 
• 
• 
• 

17

PIONEER NATURAL RESOURCES COMPANY

• 
• 
• 

the effect of energy conservation efforts;
the proximity, capacity, cost and availability of pipelines and other transportation facilities; and
the price and availability of alternative fuels.

In the past, commodity prices have been extremely volatile, and the Company expects this volatility to continue. For example, 
during 2013, oil prices fluctuated from a low of $86.68 per BBL in April to a high of $110.53 per BBL in September, while gas 
prices fluctuated from a low of $3.11 per MCF in January to a high of $4.46 per MCF in December. During 2012, oil prices 
fluctuated from a high of $109.77 per BBL in February to a low of $77.69 per BBL in June, while gas prices fluctuated from a 
low of $1.91 per MCF in April to a high of $3.90 per MCF in November. The Company makes price assumptions that are used 
for planning purposes, and a significant portion of the Company's cash outlays, including rent, salaries and noncancelable capital 
commitments, are largely fixed in nature. Accordingly, if commodity prices are below the expectations on which these commitments 
were based, the Company's financial results are likely to be adversely and disproportionately affected because these cash outlays 
are not variable in the short term and cannot be quickly reduced to respond to unanticipated decreases in commodity prices.

Significant or extended price declines could also adversely affect the amount of oil, NGL and gas that the Company can 
produce economically. A reduction in production could result in a shortfall in expected cash flows and require the Company to 
reduce capital spending or borrow funds to cover any such shortfall. Any of these factors could negatively affect the Company's 
ability to replace its production and its future rate of growth.

The Company could experience periods of higher costs if commodity prices rise. These increases could reduce the Company's 
profitability, cash flow and ability to complete development activities as planned.

Historically, the Company's capital and operating costs have risen during periods of increasing oil, NGL and gas prices. 
These cost increases result from a variety of factors beyond the Company's control, such as increases in the cost of electricity, 
steel and other raw materials that the Company and its vendors rely upon; increased demand for labor, services and materials as 
drilling activity increases; and increased taxes. Increased levels of drilling activity in the oil and gas industry in recent periods 
have led to increased costs of some drilling equipment, materials and supplies. Such costs may rise faster than increases in the 
Company's revenue, thereby negatively impacting the Company's profitability, cash flow and ability to complete development 
activities as scheduled and on budget. This impact may be magnified to the extent that the Company's ability to participate in the 
commodity price increases is limited by its derivative risk management activities.

The Company's derivative risk management activities could result in financial losses.

To mitigate the effect of commodity price volatility on the Company's net cash provided by operating activities, support 
the Company's annual capital budgeting and expenditure plans and reduce commodity price risk associated with certain capital 
projects, the Company's strategy is to enter into derivative arrangements covering a portion of its oil, NGL and gas production. 
These derivative arrangements are subject to MTM accounting treatment, and the changes in fair market value of the contracts 
are reported in the Company's statements of operations each quarter, which may result in significant noncash gains or losses. These 
derivative contracts may also expose the Company to risk of financial loss in certain circumstances, including when:

• 
• 
• 

production is less than the contracted derivative volumes;
the counterparty to the derivative contract defaults on its contract obligations; or
the derivative contracts limit the benefit the Company would otherwise receive from increases in commodity prices.

On the other hand, failure to protect against declines in commodity prices exposes the Company to reduced liquidity when 

prices decline.

The failure by counterparties to the Company's derivative risk management activities to perform their obligations could have 
a material adverse effect on the Company's results of operations.

The use of derivative risk management transactions involves the risk that the counterparties will be unable to meet the 
financial terms of such transactions. If any of these counterparties were to default on its obligations under the Company's derivative 
arrangements, such a default could have a material adverse effect on the Company's results of operations, and could result in a 
larger percentage of the Company's future production being subject to commodity price changes.

 Exploration and development drilling may not result in commercially productive reserves.

Drilling involves numerous risks, including the risk that no commercially productive oil or gas reservoirs will be encountered. 
The cost of drilling, completing and operating wells is often uncertain and drilling operations may be curtailed, delayed or canceled, 
or become costlier, as a result of a variety of factors, including:

• 

unexpected drilling conditions;

18

PIONEER NATURAL RESOURCES COMPANY

• 
• 
• 
• 
• 
• 

unexpected pressure or irregularities in formations;
equipment failures or accidents;
fracture stimulation accidents or failures;
adverse weather conditions;
restricted access to land for drilling or laying pipelines; and
access to, and the cost and availability of, the equipment, services, resources and personnel required to complete the 
Company's drilling, completion and operating activities.

The Company's future drilling activities may not be successful and, if unsuccessful, such failure could have an adverse 
effect on the Company's future results of operations and financial condition. While all drilling, whether developmental, extension 
or  exploratory,  involves  these  risks,  exploratory  and  extension  drilling  involves  greater  risks  of  dry  holes  or  failure  to  find 
commercial quantities of hydrocarbons. The Company expects that it will continue to experience exploration and abandonment 
expense in 2014.

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

Declines in commodity prices may result in the Company having to make substantial downward adjustments to its estimated 
proved reserves. If this occurs, or if the Company's estimates of production or economic factors change, accounting rules may 
require the Company to impair, as a noncash charge to earnings, the carrying value of the Company's oil and gas properties. The 
Company is required to perform impairment tests on proved oil and gas properties whenever events or changes in circumstances 
indicate that the carrying value of proved properties may not be recoverable. To the extent such tests indicate a reduction of the 
estimated  useful  life  or  estimated  future  cash  flows  of  the  Company's  oil  and  gas  properties,  the  carrying  value  may  not  be 
recoverable and therefore an impairment charge would be required to reduce the carrying value of the proved properties to their 
fair value. For example, during 2013, 2012 and 2011, the Company recognized impairment charges of $1.5 billion, $532.6 million 
and $354.4 million, respectively, due to the impairment of the Company's Raton field, Barnett Shale field, and Edwards and Austin 
Chalk gas fields in South Texas, respectively, due to declines in long-term gas prices and downward adjustments to the economically 
recoverable  resource  potential. The  Company  may  incur  impairment  charges  in  the  future,  which  could  materially  affect  the 
Company's results of operations in the period incurred.

The Company periodically evaluates its unproved oil and gas properties and could be required to recognize noncash charges 
in the earnings of future periods.

At December 31, 2013, the Company carried unproved oil and gas property costs of $123.4 million. GAAP requires periodic 
evaluation of these costs on a project-by-project basis. These evaluations are affected by the results of exploration activities, 
commodity price outlooks, planned future sales or expiration of all or a portion of the leases, and contracts and permits appurtenant 
to such projects. If the quantity of potential reserves determined by such evaluations is not sufficient to fully recover the cost 
invested in each project, the Company will recognize noncash charges in the earnings of future periods.

The Company periodically evaluates its goodwill for impairment and could be required to recognize noncash charges in the 
earnings of future periods.

At December 31, 2013, the Company carried goodwill of $274.3 million. Goodwill is assessed for impairment annually 
during the third quarter and whenever facts or circumstances indicate that the carrying value of the Company's goodwill may be 
impaired, which may require an estimate of the fair values of the reporting unit's assets and liabilities. Those assessments may be 
affected by (a) additional reserve adjustments both positive and negative, (b) results of drilling activities, (c) management's outlook 
for commodity prices and costs and expenses, (d) changes in the Company's market capitalization, (e) changes in the Company's 
weighted average cost of capital and (f) changes in income taxes. If the fair value of the reporting unit's net assets is not sufficient 
to fully support the goodwill balance in the future, the Company will reduce the carrying value of goodwill for the impaired value, 
with a corresponding noncash charge to earnings in the period in which goodwill is determined to be impaired.

The Company may be unable to make attractive acquisitions, and any acquisition it completes is subject to substantial risks 
that could adversely affect its business.

Acquisitions of producing oil and gas properties have from time to time contributed to the Company's growth. The Company's 
growth following the full development of its existing property base could be impeded if it is unable to acquire additional oil and 
gas reserves on a profitable basis. Acquisition opportunities in the oil and gas industry are very competitive, which can increase 
the cost of, or cause the Company to refrain from, completing acquisitions. The success of any acquisition will depend on a number 
of factors and involves potential risks, including among other things:

19

PIONEER NATURAL RESOURCES COMPANY

• 

• 

• 
• 
• 
• 

the inability to estimate accurately the costs to develop the reserves, the recoverable volumes of reserves, rates of future 
production and future net cash flows attainable from the reserves;
the assumption of unknown liabilities, losses or costs for which the Company is not indemnified or for which the 
indemnity the Company receives is inadequate;
the validity of assumptions about costs, including synergies;
the effect on the Company's 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 the Company's growing business and 
assets.

All of these factors affect whether an acquisition will ultimately generate cash flows sufficient to provide a suitable return 
on investment. Even though the Company performs a review of the properties it seeks to acquire that it believes is consistent with 
industry practices, such reviews are often limited in scope. As a result, among other risks, the Company's initial estimates of 
reserves may be subject to revision following an acquisition, which may materially and adversely affect the desired benefits of 
the acquisition.

The Company's ability to complete dispositions of assets, or interests in assets, may be subject to factors beyond its control, 
and in certain cases the Company may be required to retain liabilities for certain matters.

From time to time, the Company sells an interest in a strategic asset for the purpose of assisting or accelerating the asset's 
development. In addition, the Company regularly reviews its property base for the purpose of identifying nonstrategic assets, the 
disposition  of  which  would  increase  capital  resources  available  for  other  activities  and  create  organizational  and  operational 
efficiencies. Various factors could materially affect the ability of the Company to dispose of such interests or nonstrategic assets 
or complete announced dispositions, including the receipt of approvals of governmental agencies or third parties and the availability 
of purchasers willing to acquire the interests or purchase the nonstrategic assets on terms and at prices acceptable to the Company. 

Sellers typically retain certain liabilities or indemnify buyers for certain matters. The magnitude of any such retained liability 
or indemnification obligation may be difficult to quantify at the time of the transaction and ultimately may be material. Also, as 
is typical in divestiture transactions, third parties may be unwilling to release the Company from guarantees or other credit support 
provided prior to the sale of the divested assets. As a result, after a divestiture, the Company may remain secondarily liable for 
the obligations guaranteed or supported to the extent that the buyer of the assets fails to perform these obligations.

The Company's gas processing operations are subject to operational risks, which could result in significant damages and the 
loss of revenue.

As  of  December  31,  2013,  the  Company  owned  interests  in  six  gas  processing  plants  and  nine  treating  facilities. The 
Company is the operator of two of the gas processing plants and all nine of the treating facilities. There are significant risks 
associated with the operation of gas processing plants. Gas and NGLs are volatile and explosive and may include carcinogens. 
Damage to or improper operation of a gas processing plant or facility could result in an explosion or the discharge of toxic gases, 
which could result in significant damage claims in addition to interrupting a revenue source.

 The Company's operations involve many operational risks, some of which could result in unforeseen interruptions to the 
Company's operations and substantial losses to the Company for which the Company may not be adequately insured.

The Company's operations, including well stimulation and completion activities, such as hydraulic fracturing, are subject 

to all the risks normally incident to the oil and gas development and production business, including:

• 
• 
• 

• 
• 
• 
• 
• 
• 
• 
• 

blowouts, cratering, explosions and fires;
adverse weather effects;
environmental hazards, such as gas leaks, oil spills, pipeline and vessel ruptures, encountering NORM, and unauthorized 
discharges of toxic gases, brine, well stimulation and completion fluids or other pollutants into the surface and subsurface 
environment;
high costs, shortages or delivery delays of equipment, labor or other services or water for hydraulic fracturing;
facility or equipment malfunctions, failures or accidents;
title problems;
pipe or cement failures or casing collapses;
compliance with environmental and other governmental requirements;
lost or damaged oilfield workover and service tools;
unusual or unexpected geological formations or pressure or irregularities in formations; and
natural disasters.

20

 
PIONEER NATURAL RESOURCES COMPANY

The Company's overall exposure to operational risks may increase as its drilling activity expands and as it seeks to directly 
provide drilling, fracture stimulation and other services internally. Any of these risks could result in substantial losses to the 
Company  due  to  injury  or  loss  of  life,  damage  to  or  destruction  of  wells,  production  facilities  or  other  property,  clean-up 
responsibilities, regulatory investigations and penalties and suspension of operations.

The Company is not fully insured against certain of the risks described above, either because such insurance is not available 
or because of the high premium costs and deductibles associated with obtaining such insurance. Additionally, the Company relies 
to a large extent on facilities owned and operated by third-parties, and damage to or destruction of those third-party facilities could 
affect the ability of the Company to produce, transport and sell its hydrocarbons.

Part of the Company's strategy involves using some of the latest available horizontal drilling and completion techniques, which 
involve risks and uncertainties in their application.

The Company's operations involve utilizing some of the latest drilling and completion techniques as developed by it and 
its service providers. Risks that the Company faces while drilling horizontal wells include, but are not limited to, the following:

• 
• 
• 
• 

 landing the wellbore in the desired drilling zone;
 staying in the desired drilling zone while drilling horizontally through the formation;
 running casing the entire length of the wellbore; and
 being able to run tools and other equipment consistently through the horizontal wellbore.

Risks that the Company faces while completing wells include, but are not limited to, the following:

• 
• 
• 

 the ability to fracture stimulate the planned number of stages;
 the ability to run tools the entire length of the wellbore during completion operations; and
 the ability to successfully clean out the wellbore after completion of the final fracture stimulation stage.

The results of drilling in emerging areas are more uncertain initially than drilling results in areas that are more developed 
and have a longer history of established production. New discoveries and emerging formations have limited or no production 
history and, consequently, the Company is more limited in assessing future drilling results in these areas. If the Company's drilling 
results are worse than anticipated, the return on investment for a particular project may not be as attractive as anticipated and the 
Company may recognize noncash impairment charges to reduce the carrying value of its unproved properties.

The  Company's  expectations  for  future  drilling  activities  will  be  realized  over  several  years,  making  them  susceptible  to 
uncertainties that could materially alter the occurrence or timing of such activities.

The  Company  has  identified  drilling  locations  and  prospects  for  future  drilling  opportunities,  including  development, 
exploratory and infill drilling activities. These drilling locations and prospects represent a significant part of the Company's future 
drilling plans. For example, the Company's proved reserves as of December 31, 2013 include proved undeveloped reserves and 
proved developed reserves that are behind pipe of 102.5 MMBBLs of oil, 41.9 MMBBLs of NGLs and 328.9 BCF of gas. The 
Company's ability to drill and develop these locations depends on a number of factors, including the availability of capital, seasonal 
conditions, regulatory approvals, negotiation of agreements with third parties, commodity prices, costs, access to and availability 
of equipment, services, resources and personnel and drilling results.  Changes in the laws or regulations on which the Company 
relies in planning and executing its drilling programs could adversely impact the Company's ability to successfully complete those 
programs.  For example, under current Texas laws and regulations the Company may receive permits to drill, and may drill and 
complete, certain horizontal wells that traverse one or more units and/or leases; a change in those laws or regulations could adversely 
impact the Company's ability to drill those wells. Because of these uncertainties, the Company cannot give any assurance as to 
the  timing  of  these  activities  or  that  they  will  ultimately  result  in  the  realization  of  proved  reserves  or  meet  the  Company's 
expectations  for  success. As  such,  the  Company's  actual  drilling  activities  may  materially  differ  from  the  Company's  current 
expectations, which could have a significant adverse effect on the Company's proved reserves, financial condition and results of 
operations.

The Company may not be able to obtain access on commercially reasonable terms or otherwise to pipelines and storage facilities, 
gas gathering systems and other transportation, processing, fractionation and refining facilities to market its oil, NGL and gas 
production; the Company relies on a limited number of purchasers for a majority of its products.

The marketing of oil, NGL and gas production depends in large part on the availability, proximity and capacity of pipelines 
and storage facilities, gas gathering systems and other transportation, processing, fractionation and refining facilities, as well as 
the existence of adequate markets. If there were insufficient capacity available on these systems, if these systems were unavailable 
to the Company, or if access to these systems were to become commercially unreasonable, the price offered for the Company's 
production could be significantly depressed, or the Company could be forced to shut in some production or delay or discontinue 

21

PIONEER NATURAL RESOURCES COMPANY

drilling plans and commercial production following a discovery of hydrocarbons while it constructs its own facility or awaits the 
availability of third party facilities. The Company also relies (and expects to rely in the future) on facilities developed and owned 
by third parties in order to store, process, transport, fractionate and sell its oil, NGL and gas production. The Company's plans to 
develop and sell its oil and gas reserves could be materially and adversely affected by the inability or unwillingness of third parties 
to provide sufficient transportation, storage or processing and fractionation facilities to the Company, especially in areas of planned 
expansion where such facilities do not currently exist.

 For example, following Hurricanes Gustav and Ike in 2008, certain Permian Basin gas processors were forced to shut down 
their plants due to the shutdown of the Texas Gulf Coast NGL fractionators. The Company was able to produce its oil wells and 
vent or flare the associated gas; however, there is no certainty the Company will be able to vent or flare gas in the future due to 
potential changes in regulations. The amount of oil and gas that can be produced is subject to limitation in certain circumstances, 
such as pipeline interruptions due to scheduled and unscheduled maintenance, excessive pressure, physical damage to the gathering, 
transportation, refining or processing facilities, or lack of capacity on such facilities. The Company has periodically experienced 
high line pressure at its tank batteries, which has occasionally led to the flaring of gas due to the inability of the gas gathering 
systems in the areas to support the increased gas production. The curtailments arising from these and similar circumstances may 
last from a few days to several months, and in many cases, the Company may be provided only limited, if any, notice as to when 
these circumstances will arise and their duration.

To the extent that the Company enters into transportation contracts with gas pipelines that are subject to FERC regulation, 
the Company is subject to FERC requirements related to use of such capacity.  Any failure on the Company's part to comply with 
FERC's regulations and policies or with an interstate pipeline's tariff could result in the imposition of civil and criminal penalties.

A limited number of companies purchase a majority of the Company's oil, NGLs and gas. The loss of a significant purchaser 

could have a material adverse effect on the Company's ability to sell its production.

The Company is growing production in areas of high industry activity, which may affect its ability to obtain the personnel, 
equipment, services, resources and facilities access needed to complete its development activities as planned or result in increased 
costs.

The Company's operations and drilling activity are concentrated in areas in which industry activity has increased rapidly, 
particularly in the Spraberry field in West Texas and the Eagle Ford Shale play in South Texas. As a result, demand for personnel, 
equipment, power, services and resources, as well as access to transportation, processing and refining facilities in these areas, has 
increased, as have the costs for those items. In addition, hydraulic fracturing and other operations require significant quantities of 
water, which supply may be affected by drought conditions. Any delay or inability to secure the personnel, equipment, power, 
services, resources and facilities access necessary for the Company to complete its planned development activities, including the 
result of any changes in laws or regulations applicable to the Company's operations relating to water usage, could result in oil and 
gas production volumes being below the Company's forecasted volumes. In addition, any such negative effect on production 
volumes, or significant increases in costs, could have a material adverse effect on the Company's cash flow and profitability. 

The refining industry may be unable to absorb rising U.S. oil and condensate production; in such a case, the resulting surplus 
could depress prices and restrict the availability of markets.

Under U.S. law and regulations, the export of oil and certain condensates is restricted.  Absent a change in this law or an 
expansion of U.S. refining capacity, rising U.S. production of oil and condensate could result in a surplus of these products, which 
would likely cause prices for these commodities to fall and markets to constrict. In such circumstances, the returns on the Company’s 
capital projects would decline, possibly to levels that would make execution of the Company’s drilling plans uneconomical, and 
a lack of market for the Company's products could require that the Company shut in some portion of its production.  If this were 
to occur, the Company’s production and cash flow could decrease, or could increase less than forecasted, which could have a 
material adverse effect on the Company's cash flow and profitability.

The nature of the Company's assets and production operations exposes it to significant costs and liabilities with respect to 
environmental and occupational health and safety matters.

The oil and gas business involves the production, handling, sale and disposal of environmentally sensitive materials and is 
subject to environmental hazards, such as oil spills, produced water spills, gas leaks, pipeline and vessel ruptures and unauthorized 
discharges of substances or gases, that could expose the Company to substantial liability due to pollution and other environmental 
damage. Pollution and similar environmental risks generally are not fully insurable either because such insurance is not available 
or because of the high premium costs and deductible associated with obtaining such insurance. A variety of federal, state and local 
laws and regulations govern the environmental aspects of the oil and gas business. Noncompliance with these laws and regulations 
may subject the Company to administrative, civil or criminal penalties, remedial cleanups, and natural resource damages or other 
liabilities, and compliance with these laws and regulations may increase the cost of the Company's operations. Such laws and 

22

PIONEER NATURAL RESOURCES COMPANY

regulations  may  also  affect  the  costs  of  acquisitions.  See  "Item  1.  Business  —  Competition,  Markets  and  Regulations  — 
Environmental and occupational health and safety matters" above for additional discussion related to environmental risks.

Environmental laws and regulations are subject to amendment or replacement by more stringent laws and regulations and 
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,  result  in  a  material  increase  in  the  costs  of  production,  development, 
exploration or processing operations or adversely affect the Company's future operations and financial condition. 

The Company could incur significant costs and liabilities in responding to contamination that occurs at its properties or as a 
result of its operations.

There is inherent risk of incurring significant environmental costs and liabilities in operations upon the Company's properties 
due to its handling of petroleum hydrocarbons and wastes, because of air emissions and water discharges related to its operations, 
and as a result of historical operations and waste disposal practices by prior owners and operators.  The Company currently owns, 
leases or operates properties that for many years have been used for oil and gas exploration and production activities, and petroleum 
hydrocarbons, hazardous substances and wastes have been released on or under such properties and could be released during future 
operations.  Joint and several strict liabilities may be incurred in connection with such releases of petroleum hydrocarbons and 
wastes on, under or from the Company's properties.  Private parties, including lessors of properties on which the Company operates 
and the owners or operators of properties adjacent to the Company's operations and facilities where the Company's petroleum 
hydrocarbons or wastes are taken for reclamation or disposal, may also have the right to pursue legal actions to enforce compliance 
as well as seek damages for noncompliance with environmental laws and regulations or for personal injury or property damage.  
The Company may not be able to recover some or any of these costs from insurance or other sources of contractual indemnity.

The Company's credit facility and debt instruments have substantial restrictions and financial covenants that may restrict its 
business and financing activities.

The Company is a borrower under fixed rate senior notes and a credit facility. The terms of the Company's borrowings 
specify scheduled debt repayments and require the Company to comply with certain associated covenants and restrictions. The 
Company's ability to comply with the debt repayment terms, associated covenants and restrictions is dependent on, among other 
things,  factors  outside  the  Company's  direct  control,  such  as  commodity  prices  and  interest  rates.  See  Note  G  of  Notes  to 
Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for information regarding 
the Company's outstanding debt as of December 31, 2013 and the terms associated therewith.

The Company's ability to obtain additional financing is also affected by the Company's debt credit ratings and competition 

for available debt financing.

 The Company faces significant competition, and some of its competitors have resources in excess of the Company's 
available resources.

The oil and gas industry is highly competitive. The Company competes with a large number of companies, producers and 

operators in a number of areas such as:

seeking to acquire oil and gas properties suitable for development or exploration;

• 
•  marketing oil, NGL and gas production; and
• 

seeking to acquire the equipment and expertise, including trained personnel, necessary to evaluate, operate and develop 
properties.

Some of the Company's competitors are larger and have substantially greater financial and other resources than the Company. 

See "Item 1. Business — Competition, Markets and Regulations" for additional discussion regarding competition.

The Company is subject to regulations that may cause it to incur substantial costs.

The Company's business is regulated by a variety of federal, state and local laws and regulations. For instance, in connection 
with the Company's CBM operations in the Raton Basin in Colorado, the Colorado Supreme Court affirmed a state water court 
holding  that  water  produced  in  connection  with  CBM  operations  should  be  subject  to  state  water-use  regulations,  including 
regulations requiring permits for diversion and use of surface and subsurface water, an evaluation of potential competing permits, 
possible uses of the water and a possible requirement to provide augmentation water supplies for water rights owners with more 
senior rights. As another example, the underground injection well program under the SDWA requires permits from the EPA or an 
analogous state agency for the Company's disposal wells, establishes minimum standards for injection well operations, and restricts 
the types and quantities of fluids that may be injected. In some areas of Texas, there has been concern that certain formations into 
which disposal wells are injecting produced waters could become over-pressured after many years of injection, and the governing 
Texas regulatory agency is reviewing the data to determine whether any action is necessary to address this issue. If the Texas state 
23

PIONEER NATURAL RESOURCES COMPANY

agency were to decline to issue permits for new injection wells into the formations currently utilized by the Company, the Company 
may be required to seek alternative methods of disposing of produced waters, including injecting into deeper formations, which 
could increase its costs.  There can be no assurance that present or future regulations will not adversely affect the Company's 
business and operations, including that the Company may be required to suspend drilling operations or shut in production pending 
compliance. See "Item 1. Business — Competition, Markets and Regulations" for additional discussion regarding government 
regulation.

The  Company's  sales  of  oil,  gas,  NGLs  or  other  energy  commodities,  and  any  derivative  activities  related  to  such  energy 
commodities, expose the Company to potential regulatory risks.

FERC, the FTC and the CFTC hold statutory authority to monitor certain segments of the physical and futures energy 
commodities markets relevant to the Company's business. These agencies have imposed broad regulations prohibiting fraud and 
manipulation of such markets. With regard to the Company's physical sales of oil, gas, NGLs or other energy commodities, and 
any derivative activities related to these energy commodities, the Company is required to observe the market-related regulations 
enforced by these agencies, which hold substantial enforcement authority. Failure to comply with such regulations, as interpreted 
and enforced, could materially and adversely affect the Company's business results of operations and financial condition.

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

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

Petroleum  engineering  is  a  subjective  process  of  estimating  underground  accumulations  of  oil  and  gas  that  cannot  be 
measured in an exact manner. Estimates of economically recoverable oil and gas reserves and estimates 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 quality and quantity of available data;
the interpretation of that data;
the assumed effects of regulations by governmental agencies;
assumptions concerning future commodity prices; and
assumptions  concerning  future  operating  costs,  severance,  ad  valorem  and  excise  taxes,  development  costs, 
transportation costs and workover and remedial costs.

Because all proved reserve estimates are to some degree subjective, each of the following items may differ materially from 

those assumed in estimating proved reserves:

• 
• 
• 
• 

the quantities of oil and gas that are ultimately recovered;
the production costs incurred to recover the reserves;
the amount and timing of future development expenditures; and
future commodity prices.

Furthermore, different reserve engineers may make different estimates of proved reserves and cash flows based on the same 
available data. The Company's actual production, revenues and expenditures with respect to proved 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 average 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, NGLs and gas; and
changes in governmental regulations or taxation.

Standardized Measure is a reporting convention that provides a common basis for comparing oil and gas companies subject 
to  the  rules  and  regulations  of  the  SEC.  In  general,  it  requires  the  use  of  commodity  prices  that  are  based  upon  a  12-month 
unweighted average, as well as operating and development costs being incurred at the end of the reporting period. Consequently, 
it may not reflect the prices ordinarily received or that will be received for oil and gas production because of seasonal price 
fluctuations or other varying market conditions, nor may it reflect the actual costs that will be required to produce or develop the 
24

PIONEER NATURAL RESOURCES COMPANY

oil and 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 ten percent discount factor, which is required by 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 the Company or the oil and gas industry in general. Therefore, 
the estimates of discounted future net cash flows or Standardized Measure in this Report should not be construed as accurate 
estimates of the current market value of the Company's proved reserves.

The Company's actual production could differ materially from its forecasts.

From time to time, the Company provides forecasts of expected quantities of future oil and gas production. These forecasts 
are based on a number of estimates, including expectations of production from existing wells and the outcome of future drilling 
activity.  Should  these  estimates  prove  inaccurate,  actual  production  could  be  adversely  affected.  In  addition,  the  Company's 
forecasts assume that none of the risks associated with the Company's oil and gas operations summarized in this "Item 1A. Risk 
Factors" occur, such as facility or equipment malfunctions, adverse weather effects, or downturns in commodity prices or significant 
increases in costs, which could make certain drilling activities or production uneconomical.

The Company's business could be negatively affected by security threats, including cybersecurity threats, and other disruptions.

As an oil and gas producer, the Company faces various security threats, including cybersecurity threats to gain unauthorized 
access  to  sensitive  information  or  to  render  data  or  systems  unusable;  threats  to  the  security  of  the  Company's  facilities  and 
infrastructure or third party facilities and infrastructure, such as processing plants and pipelines; and threats from terrorist acts. 
The potential for such security threats has subjected the Company's operations to increased risks that could have a material adverse 
effect on the Company's business. In particular, the Company's implementation of various procedures and controls to monitor and 
mitigate security threats and to increase security for the Company's information, facilities and infrastructure may result in increased 
capital and operating costs. Moreover, there can be no assurance that such procedures and controls will be sufficient to prevent 
security breaches from occurring. If any of these security breaches were to occur, they could lead to losses of sensitive information, 
critical infrastructure or capabilities essential to the Company's operations and could have a material adverse effect on the Company's 
reputation,  financial  position,  results  of  operations  or  cash  flows.  Cybersecurity  attacks  in  particular  are  becoming  more 
sophisticated and include, but are not limited to, malicious software, attempts to gain unauthorized access to data and systems, 
and other electronic security breaches that could lead to disruptions in critical systems, unauthorized release of confidential or 
otherwise protected information, and corruption of data. These events could damage the Company's reputation and lead to financial 
losses from remedial actions, loss of business or potential liability.

 A failure by purchasers of the Company's production to perform their obligations to the Company could require the 
Company to recognize a pre-tax charge in earnings and have a material adverse effect on the Company's results of 
operation.

The Company relies on a limited number of purchasers to purchase a majority of its products. To the extent that purchasers 
of the Company's production rely on access to the credit or equity markets to fund their operations, there is a risk that those 
purchasers could default in their contractual obligations to the Company if such purchasers were unable to access the credit or 
equity markets for an extended period of time. If for any reason the Company were to determine that it was probable that some 
or all of the accounts receivable from any one or more of the purchasers of the Company's production were uncollectible, the 
Company would recognize a pre-tax charge in the earnings of that period for the probable loss.

Declining general economic, business or industry conditions could have a material adverse effect on the Company's results of 
operations.

The worldwide economic outlook has been improving steadily since 2010, but if there are renewed concerns about global 
economic growth or government debt in Europe or the United States, there could be a significant adverse effect on global financial 
markets and commodity prices. If the economic climate in the United States or abroad were to deteriorate, demand for petroleum 
products could diminish, which could depress the prices at which the Company could sell its oil, NGLs and gas and ultimately 
decrease the Company's net revenue and profitability.

Certain U.S. federal income tax deductions currently available with respect to oil and gas exploration and development may 
be eliminated as a result of future legislation.

In recent years, legislation has been proposed that would, if enacted into law, make significant changes to U.S. tax laws, 
including the elimination of certain key U.S. federal income tax incentives currently available to oil and gas companies. Such tax 
legislation changes include, but are not limited to, (i) the repeal of the percentage depletion allowance for oil and gas properties, 
(ii) the elimination of current deductions for intangible drilling and development costs, (iii) the elimination of the deduction for 
certain domestic production activities and (iv) an extension of the amortization period for certain geological and geophysical 

25

PIONEER NATURAL RESOURCES COMPANY

expenditures. It is unclear whether these or similar changes will be enacted and, if enacted, how soon any such changes could 
become effective. The passage of any legislation as a result of these proposals or any other similar changes in U.S. federal income 
tax laws could eliminate or postpone certain tax deductions that are currently available with respect to oil and gas exploration and 
development, and any such change could have an adverse effect on the Company's financial position, results of operations and 
cash flows.

Climate change legislation and regulatory initiatives restricting emissions of GHGs could result in increased operating costs 
and reduced demand for the oil, NGLs and gas the Company produces.

In 2009, the EPA officially published its findings that emissions of GHGs present an endangerment to public health and 
the environment because emissions of such gases are, according to the EPA, contributing to warming of the Earth's atmosphere 
and other climatic changes. Based on these findings, the EPA adopted regulations under the CAA establishing Title V and PSD 
permitting requirements for large sources of GHGs.  The Company could become subject to these permitting requirements and 
be required to install "best available control technology" to limit emissions of GHGs from any new or significantly modified 
facilities that the Company may seek to construct in the future if they would otherwise emit large volumes of GHGs. The EPA has 
also adopted rules requiring the reporting of GHG emissions on an annual basis from specified GHG emission sources in the 
United States, including certain oil and gas production facilities, which include certain of the Company's facilities. While the U.S. 
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 GHG emissions at the federal level in recent years. In the absence of federal climate legislation 
in the United States, a number of state and regional efforts have emerged that are aimed at tracking or reducing GHG emissions 
by means of cap and trade programs that typically require major sources of GHG emissions, such as electric power plants, to 
acquire and surrender emission allowances in return for emitting those GHGs. If the U.S. Congress undertakes comprehensive 
tax reform in the coming year, it is possible that such reform may include a carbon tax, which could impose additional direct costs 
on the Company's operations. Although it is not possible at this time to predict how legislation or new regulations that may be 
adopted to address GHG emissions would affect the Company's business, any such future laws and regulations could require the 
Company to incur increased operating costs, such as costs to purchase and operate emissions control systems, acquire emissions 
allowances or comply with new regulatory or reporting requirements, including the imposition of a carbon tax. Any such legislation 
or regulatory programs could also increase the cost to the consumer, and thereby reduce demand for oil and gas, which could 
reduce the demand for the oil and gas the Company produces. Consequently, legislation and regulatory programs to reduce emissions 
of GHGs could have an adverse effect on the Company's business, financial condition and results of operations. See "Item 1. 
Business - Competition, Markets and Regulations - Environmental and occupational health and safety matters - Climate change" 
for additional discussion relating to climate change.

The enactment of derivatives legislation could have an adverse effect on the Company's ability to use derivative instruments 
to reduce the effect of commodity price, interest rate and other risks associated with its business.

The  Dodd-Frank Wall  Street  Reform  and  Consumer  Protection Act  (the  "Dodd-Frank Act")  enacted  on  July  21,  2010, 
established federal oversight and regulation of the over-the-counter derivatives market and entities, such as the Company, that 
participate  in  that  market. The  Dodd-Frank Act  requires  the  CFTC  and  the  SEC  to  promulgate  rules  and  regulations  for  its 
implementation.  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. The initial position limits rule was vacated by the 
United States District Court for the District of Colombia in September 2012.  However, in November 2013, the CFTC proposed 
new rules that would place limits on positions in certain core futures and equivalent swaps contracts for or linked to certain physical 
commodities, subject to exceptions for certain bona fide derivative transactions.  As these new position limit rules are not yet final, 
the impact of those provisions on the Company is uncertain at this time. The CFTC has designated certain interest rate swaps and 
credit default swaps for mandatory clearing and the associated rules also will require the Company, 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.  Although the Company believes it qualifies for the end-user exception from the mandatory clearing requirements 
for swaps entered to mitigate its 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 Company's derivatives. 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 or what the effect of any such regulations will be on the Company. For example, for uncleared 
swaps, the CFTC or federal banking regulators may require end-users to enter into credit support documentation and/or post initial 
and variation margin. Posting of collateral could impact liquidity and reduce cash available to the Company for capital expenditures, 
therefore reducing its ability to execute derivatives to reduce risk and protect cash flows. The proposed margin rules are not yet 
final, and therefore the impact of those provisions to the Company is uncertain at this time. The Dodd-Frank Act also may require 
the counterparties to the Company's derivative instruments to spin off some of their derivatives activities to a separate entity, which 
may not be as creditworthy as the current counterparty. The full impact of the Dodd-Frank Act and related regulatory requirements 
upon the Company's business will not be known until the regulations are implemented and the market for derivatives contracts 
has adjusted. The Dodd-Frank Act and any new regulations could significantly increase the cost of derivative contracts, materially 
26

PIONEER NATURAL RESOURCES COMPANY

alter the terms of derivative contracts, reduce the availability of derivatives to protect against risks the Company encounters, reduce 
the Company's ability to monetize or restructure its existing derivative contracts, and increase the Company's exposure to less 
creditworthy counterparties. If the Company reduces its use of derivatives as a result of the Dodd-Frank Act and regulations, the 
Company's results of operations may become more volatile and its cash flows may be less predictable, which could adversely 
affect the Company's ability to plan for and fund capital expenditures. Finally, the Dodd-Frank Act was intended, in part, to reduce 
the volatility of oil and gas prices, which some legislators attributed to speculative trading in derivatives and commodity instruments 
related to oil and gas. The Company's revenues could therefore be adversely affected if a consequence of the Dodd-Frank Act and 
implementing regulations is to lower commodity prices. Any of these consequences could have a material adverse effect on the 
Company, its financial condition and its results of operations.

Federal, state and local legislative 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  the 
Company's production.

Hydraulic fracturing is a common practice that is used to stimulate production of hydrocarbons from tight formations. The 
Company routinely utilizes hydraulic fracturing techniques in the majority of its drilling and completion programs. The process 
involves the injection of water, sand and additives under pressure into targeted subsurface formations to stimulate oil and gas 
production. The  process  is  typically  regulated  by  state  oil  and  gas  commissions,  but  the  EPA  has  asserted  federal  regulatory 
authority over hydraulic fracturing involving diesel fuels under the SDWA's Underground Injection Control Program and published 
final permitting guidance in February 2014 addressing the performance of such activities. In 2011, the EPA announced its intent 
to develop and issue regulations under the Toxic Substances Control Act to require companies to disclose information regarding 
the chemicals used in hydraulic fracturing, and in its Semi-annual Regulatory agenda published in July 2013, the agency continues 
to project the future issuance of an Advance Notice of Proposed Rulemaking that would seek public input on the design and scope 
of such disclosure regulations. The EPA has published final rules under the CAA that, among other things, require producers to 
reduce volatile organic compound emissions from certain subcategories of fractured and refractured gas wells for which well 
completion operations are being conducted by routing flowback emissions to a gathering line or capturing and combusting flowback 
emissions using a combustion device, such as a flare, until January 1, 2015 and performing green completions, with or without 
combustion devices, on or after January 1, 2015. Also, in May 2013, the BLM published a supplemental notice of proposed 
rulemaking governing hydraulic fracturing on federal and Indian oil and gas leases that would require public disclosure of chemicals 
used in hydraulic fracturing, confirmation that wells used in fracturing operations meet appropriate construction standards, and 
development of appropriate plans for managing flowback water that returns to the surface.

In  addition,  the  U.S.  Congress,  from  time  to  time,  has  considered  adopting  legislation  intended  to  provide  for  federal 
regulation of hydraulic fracturing and to require disclosure of the chemicals used in the hydraulic-fracturing process. Certain states 
in which the Company operates, including Colorado and Texas have adopted, and other states are considering adopting, regulations 
that  could  impose  new  or  more  stringent  permitting,  disclosure,  and  well-construction  requirements  on  hydraulic-fracturing 
operations. In addition, local land use restrictions, such as city ordinances, may restrict or prohibit drilling in general or hydraulic 
fracturing  in  particular.  In  the  event  federal,  state  or  local  restrictions  are  adopted  in  areas  where  the  Company  is  currently 
conducting, or in the future plan to conduct operations, the Company may incur additional costs to comply with such requirements 
that  may  be  significant  in  nature,  experience  delays  or  curtailment  in  the  pursuit  of  exploration,  development,  or  production 
activities, and perhaps be limited or precluded in the drilling of wells or in the amounts that the Company is ultimately able to 
produce from its reserves.

Certain governmental reviews were recently conducted or are underway that focus on environmental aspects of hydraulic 
fracturing  practices.  The  White  House  Council  on  Environmental  Quality  is  coordinating  an  administration-wide  review  of 
hydraulic fracturing practices. The EPA has commenced a study of the potential environmental effects of hydraulic fracturing on 
drinking  water  and  groundwater  and  a  draft  report  is  expected  to  be  available  for  public  comment  and  peer  review  in  2014. 
Moreover,  the  EPA  is  developing  effluent  limitations  for  the  treatment  and  discharge  of  wastewater  resulting  from  hydraulic 
fracturing activities and is expected to propose these standards in 2014. These studies, or future studies, depending on their degree 
of pursuit and any meaningful results obtained, could spur initiatives to further regulate hydraulic fracturing under the SDWA or 
other regulatory mechanisms. See "Item 1. Business - Competition, Markets and Regulations - Environmental and occupational 
health  and  safety  matters"  for  additional  discussion  related  to  environmental  risks  associated  with  the  Company's  hydraulic 
fracturing activities.

Laws and regulations pertaining to threatened and endangered species could delay or restrict the Company's operations and 
cause it to incur substantial costs.

Various federal and state statutes prohibit certain actions that adversely affect endangered or threatened species and their 
habitats, migratory birds, wetlands and natural resources. These statutes include the ESA, the Migratory Bird Treaty Act, the CWA 
and CERCLA. The U.S. Fish and Wildlife Service may designate critical habitat and suitable habitat areas that it believes are 

27

PIONEER NATURAL RESOURCES COMPANY

necessary for survival of threatened or endangered species. A critical habitat or suitable habitat designation could result in further 
material restrictions to federal land use and private land use and could delay or prohibit land access or oil and gas development. 
If harm to species or damages to wetlands, habitat or natural resources occur or may occur, government entities or, at times, private 
parties may act to prevent oil and gas exploration or development activities or seek damages for harm to species, habitat or natural 
resources resulting from drilling or construction or releases of oil, wastes, hazardous substances or other regulated materials, and, 
in some cases, may seek criminal penalties. Moreover, as a result of a settlement approved by the U.S. District Court for the District 
of Columbia in September 2011, the U.S. Fish and Wildlife Service is required to make a determination on the listing of numerous 
species as endangered or threatened under the ESA before completion of the agency's 2017 fiscal year.  The designation of previously 
unprotected species as threatened or endangered in areas where the Company conducts operations could cause the Company to 
incur increased costs arising from species protection measures or could result in limitations on its development and production 
activities that could have an adverse effect on the Company's ability to develop and produce reserves.

Provisions of the Company's charter documents and Delaware law may inhibit a takeover, which could limit the price investors 
might be willing to pay in the future for the Company's common stock.

Provisions in the Company's certificate of incorporation and bylaws may have the effect of delaying or preventing an 
acquisition of the Company or a merger in which the Company is not the surviving company and may otherwise prevent or slow 
changes in the Company's board of directors and management. In addition, because the Company is incorporated in Delaware, it 
is governed by the provisions of Section 203 of the Delaware General Corporation Law. These provisions could discourage an 
acquisition of the Company or other change in control transaction and thereby negatively affect the price that investors might be 
willing to pay in the future for the Company's common stock.

The Company's sand mining operations are subject to operating risks that are often beyond the Company's control, and such 
risks may not be covered by insurance.

Ownership of industrial sand mining operations are subject to risks, many of which are beyond the Company's control. 

These risks include:

• 
• 
• 
• 
• 

• 
• 
• 
• 
• 
• 
• 
• 
• 
• 

unusual or unexpected geological formations or pressures;
cave-ins, pit wall failures or rock falls;
unanticipated ground, grade or water conditions;
inclement or hazardous weather conditions, including flooding, and the physical impacts of climate change;
environmental hazards, such as unauthorized spills, releases and discharges of wastes, vessel ruptures and emission of 
unpermitted levels of pollutants;
changes in laws and regulations;
inability to acquire or maintain necessary permits or mining or water rights;
restrictions on blasting operations;
inability to obtain necessary production equipment or replacement parts;
reduction in the amount of water available for processing;
technical difficulties or failures;
labor disputes;
late delivery of supplies;
fires, explosions or other accidents; and
facility interruptions or shutdowns in response to environmental regulatory actions.

Any of these risks could result in damage to, or destruction of, the Company's mining properties or production facilities, 
personal injury, environmental damage, delays in mining or processing, losses or possible legal liability. Not all of these risks are 
insurable,  and  the  Company's  insurance  coverage  contains  limits,  deductibles,  exclusions  and  endorsements. The  Company's 
insurance coverage may not be sufficient to meet its needs in the event of loss and any such loss may have a material adverse 
effect on the Company. 

The Company's estimates of sand reserves and resource deposits are imprecise and actual reserves could be less than estimated.

The Company bases its sand reserve and resource estimates on engineering, economic and geological data assembled and 
analyzed  by  engineers  and  geologists,  which  are  periodically  reviewed  by  outside  firms.  However,  commercial  sand  reserve 
estimates are necessarily imprecise and depend to some extent on statistical inferences drawn from available drilling data, which 
may prove unreliable. There are numerous uncertainties inherent in estimating quantities and qualities of commercial sand reserves 
and  costs  to  mine  recoverable  reserves,  including  many  factors  beyond  the  Company's  control.  Estimates  of  economically 
recoverable  commercial  sand  reserves  necessarily  depend  on  a  number  of  factors  and  assumptions,  all  of  which  may  vary 
considerably from actual results, such as:

28

PIONEER NATURAL RESOURCES COMPANY

• 

• 

• 

geological and mining conditions or effects from prior mining that may not be fully identified by available data or that 
may differ from experience;
assumptions concerning future prices of commercial sand products, operating costs, mining technology improvements, 
development costs and reclamation costs; and
assumptions  concerning  future  effects  of  regulation,  including  the  issuance  of  required  permits  and  taxes  by 
governmental agencies.

The Company's sand mining operations are subject to extensive environmental and occupational health and safety regulations 
that impose significant costs and potential liabilities. 

The Company's sand mining operations are subject to a variety of federal, state and local environmental requirements 
affecting  the  mining  and  mineral  processing  industry,  including,  among  others,  those  relating  to  employee  health  and  safety, 
environmental permitting and licensing, air emissions and water discharges, GHG emissions, water pollution, waste management 
and disposal, remediation of soil and groundwater contamination, land use restrictions, reclamation and restoration of properties, 
hazardous materials and natural resources. Some environmental laws impose substantial penalties for noncompliance, and others, 
such as the CERCLA, impose strict, retroactive and joint and several liability for the remediation of releases of hazardous substances. 
Failure to properly handle, transport, store or dispose of hazardous materials or otherwise conduct the Company's sand mining 
operations in compliance with environmental laws could expose the Company to liability for governmental penalties, cleanup 
costs and civil or criminal liability associated with releases of such materials into the environment, damages to property or natural 
resources and other damages, as well as potentially impair the Company's ability to conduct its sand mining operations. In addition, 
environmental laws and regulations are subject to amendment, replacement or interpretation by more stringent and comprehensive 
legal requirements. The Company's continued compliance with existing or future laws and regulations could restrict the Company's 
ability to expand its facilities or extract mineral deposits or could require the Company to acquire costly equipment or to incur 
other significant expenses in connection with its sand mining operations, which restrictions or costs could have a material adverse 
effect on the Company's sand mining operations.

Any failure by the Company to comply with applicable environmental laws and regulations in connection with its sand 

mining operations may cause governmental authorities to take actions that could adversely affect the Company, including:

• 
• 
• 

• 

issuance of administrative, civil and criminal penalties;
denial, modification or revocation of permits or other authorizations;
imposition  of  injunctive  obligations  or  other  limitations  on  the  Company's  operations,  including  interruptions  or 
cessation of operations; and
requirements to perform site investigatory, remedial or other corrective actions.

In addition to environmental regulation, the Company's sand mining operations are subject to laws and regulations relating 
to worker health and safety, including such matters as human exposure to crystalline silica dust. Several federal and state regulatory 
authorities, including the U.S. Mining Safety and Health Administration, may continue to propose changes in their regulations 
regarding workplace exposure to crystalline silica, such as permissible exposure limits and required controls and personal protective 
equipment. 

The Company's sand mining operations are subject to the Federal Mine Safety and Health Act of 1977, which imposes stringent 
health and safety standards on numerous aspects of the Company's sand mining operations.

The Company's sand mining operations are subject to the Federal Mine Safety and Health Act of 1977, as amended by the 
Mine Improvement and New Emergency Response Act of 2006, which imposes stringent health and safety standards on numerous 
aspects  of  mineral  extraction  and  processing  operations,  including  the  training  of  personnel,  operating  procedures,  operating 
equipment and other matters. The Company's failure to comply with such standards, or changes in such standards or the interpretation 
or  enforcement  thereof,  could  have  a  material  adverse  effect  on  the  Company's  sand  mining  operations  or  otherwise  impose 
significant restrictions on the Company's ability to conduct mineral extraction and processing operations.

The Company's sand mining operations are subject to extensive other regulations that impose significant costs and liabilities. 

In addition to the environmental and occupational health and safety regulation discussed above, the Company's sand 
mining operations are also subject to extensive governmental regulation on matters such as permitting and licensing requirements, 
reclamation and restoration of mining properties after mining is completed, and the effects that mining have on groundwater quality 
and availability. Also, the Company's sand mining operations require numerous governmental, environmental, mining and other 
permits, water rights and approvals authorizing operations at each sand mining facility.  

In order to obtain permits and renewals of permits in the future for its sand mining operations, the Company may be required 
to prepare and present data to governmental authorities pertaining to the effect that any such activities may have on the environment. 

29

 
PIONEER NATURAL RESOURCES COMPANY

Obtaining or renewing required permits may be delayed or prevented due to opposition by neighboring property owners, members 
of the public or other third parties and other factors beyond the Company's control. A decision by a governmental agency or other 
third party to deny or delay issuing a new or renewed permit or approval, or to revoke or substantially modify an existing permit 
or approval, could have a material adverse effect on the Company's sand mining operations at the affected facility. Current or 
future regulations could have a material adverse effect on the Company's sand mining operations and the Company may not be 
able to renew or obtain permits in the future. 

The Company's sand mining operations entail silica-related health issues and litigation that could have a material adverse 
effect on the Company. 

The inhalation of respirable crystalline silica dust is associated with the lung disease silicosis. There is evidence of an 
association between crystalline silica exposure or silicosis and lung cancer and a possible association with other diseases, including 
immune system disorders, such as scleroderma. These health risks have been, and may continue to be, a significant issue confronting 
the commercial sand industry. The actual or perceived health risks of mining, processing and handling sand could materially and 
adversely affect the Company through the threat of product liability or employee lawsuits and increased scrutiny by federal, state 
and local regulatory authorities. 

Premier Silica is named as a defendant, usually among many defendants, in numerous products liability lawsuits brought 
by or on behalf of current or former employees of Premier Silica's customers alleging damages caused by silica exposure. As of 
December 31, 2013, Premier Silica was the subject of approximately 2,200 silica exposure claims, the great majority of which 
have been inactive for many years due to the plaintiffs' failure to meet specific legal requirements to advance their claims. Almost 
all of the claims pending against Premier Silica arise out of the alleged use of Premier Silica's sand products in foundries or as an 
abrasive blast media and have been filed in the states of Texas, Florida and Missouri, although some cases have been brought in 
many other jurisdictions over the years. 

It is possible that Premier Silica will continue to have silica-related products liability claims filed against it, including claims 
that allege silica exposure for periods for which there is not insurance coverage. Any pending or future claims or inadequacies of 
insurance coverage or indemnification from the seller could have a material adverse effect on the Company's results of operations.

Reserve Estimation Procedures and Audits

The information included in this Report about the Company's proved reserves as of December 31, 2013, 2012 and 2011 is 
based on evaluations prepared by the Company's engineers and (i) audited by Netherland, Sewell & Associates, Inc. ("NSAI"), 
with respect to the Company's major properties included in its continuing operations for all periods, and (ii) with respect to the 
Company's Oooguruk field properties in Alaska, audited by Ryder Scott Company, L.P. ("RSC"), as of December 31, 2012. The 
Company has no oil and gas reserves from non-traditional sources. Additionally, the Company does not provide optional disclosure 
of probable or possible reserves. 

Reserve  estimation  procedures.  The  Company  has  established  internal  controls  over  reserve  estimation  processes  and 
procedures to support the accurate and timely preparation and disclosure of reserve estimates in accordance with SEC and GAAP 
requirements. These controls include oversight of the reserves estimation reporting processes by Pioneer's Corporate Reserves 
Group ("Corporate Reserves"), and annual external audits of substantial portions of the Company's proved reserves by NSAI.

Individual asset teams are responsible for the day-to-day management of the oil and gas activities in each of the Company's 
Permian Basin, Rockies, Mid-Continent, South Texas, Barnett Shale and Alaska asset areas (the "Asset Teams"). The Company's 
Asset Teams are each staffed with reservoir engineers and geoscientists who prepare reserve estimates at the end of each calendar 
quarter for the assets that they manage, using reservoir engineering information technology. There is shared oversight of the Asset 
Teams' reservoir engineers by the Asset Teams' managers and the Vice President of Corporate Reserves, each of whom is in turn 
subject to direct or indirect oversight by the Company's management committee ("MC"). The Company's MC is comprised of its 
Chief Executive Officer, Chief Operating Officer, Chief Financial Officer and other Executive Vice Presidents. The Asset Teams' 
reserve estimates are reviewed by the Asset Team reservoir engineers before being submitted to Corporate Reserves for further 
review.

30

PIONEER NATURAL RESOURCES COMPANY

The reserve estimates are summarized in reserve reconciliations that quantify reserve changes since the previous year end 
as revisions of previous estimates, purchases of minerals-in-place, improved recovery, extensions and discoveries, production and 
sales of minerals-in-place. All reserve estimates, material assumptions and inputs used in reserve estimates and significant changes 
in reserve estimates are reviewed for engineering and financial appropriateness and compliance with SEC and GAAP standards 
by Corporate Reserves, in consultation with the Company's accounting and financial management personnel. Annually, the MC 
reviews the reserve estimates and any differences with the reserve auditors (for the portion of the reserves audited by NSAI or 
RSC) on a consolidated basis before these estimates are approved. The engineers and geoscientists who participate in the reserve 
estimation and disclosure process periodically attend training provided by external consultants and/or through internal Pioneer 
programs. Additionally, Corporate Reserves has prepared and maintains written policies and guidelines for the Asset Teams to 
reference on reserve estimation and preparation to promote objectivity in the preparation of the Company's reserve estimates and 
SEC and GAAP compliance in the reserve estimation and reporting process.

Proved reserves audits. The proved reserve audits performed by NSAI for 2013, 2012 and 2011, and by RSC for 2012, in 
the aggregate represented 94 percent, 95 percent and 90 percent of the Company's 2013, 2012 and 2011 proved reserves, respectively; 
and 92 percent, 99 percent and 91 percent of the Company's 2013, 2012 and 2011 associated pre-tax present value of proved 
reserves discounted at ten percent, respectively.

NSAI follows the general principles set forth in the "Standards Pertaining to the Estimating and Auditing of Oil and Gas 
Reserve Information" promulgated by the Society of Petroleum Engineers (the "SPE"). A reserve audit as defined by the SPE is 
not the same as a financial audit. The SPE's definition of a reserve audit includes the following concepts:

•  A reserve audit is an examination of reserve information that is conducted for the purpose of expressing an opinion as 
to whether such reserve information, in the aggregate, is reasonable and has been presented in conformity with the 
2007  SPE  publication  entitled  "Standards  Pertaining  to  the  Estimating  and  Auditing  of  Oil  and  Gas  Reserves 
Information."

•  The estimation of reserves is an imprecise science due to the many unknown geologic and reservoir factors that cannot 
be estimated through sampling techniques. Since reserves are only estimates, they cannot be audited for the purpose 
of verifying exactness. Instead, reserve information is audited for the purpose of reviewing in sufficient detail the 
policies, procedures and methods used by a company in estimating its reserves so that the reserve auditors may express 
an opinion as to whether, in the aggregate, the reserve information furnished by a company is reasonable.

•  The methods and procedures used by a company, and the reserve information furnished by a company, must be reviewed 
in  sufficient  detail  to  permit  the  reserve  auditor,  in  its  professional  judgment,  to  express  an  opinion  as  to  the 
reasonableness  of  the  reserve  information. The  auditing  procedures  require  the  reserve  auditor  to  prepare  its  own 
estimates of reserve information for the audited properties.

In conjunction with the audit of the Company's proved reserves and associated pre-tax present value discounted at ten 
percent, Pioneer provided to NSAI its external and internal engineering and geoscience technical data and analyses. Following 
NSAI's review of that data, it had the option of honoring Pioneer's interpretations, or making its own interpretations. No data was 
withheld from NSAI. NSAI accepted without independent verification the accuracy and completeness of the historical information 
and data furnished by Pioneer with respect to ownership interest, oil and gas production, well test data, commodity prices, operating 
and development costs, and any agreements relating to current and future operations of the properties and sales of production. 
However, if in the course of its evaluations something came to its attention that brought into question the validity or sufficiency 
of any such information or data, NSAI did not rely on such information or data until it had satisfactorily resolved its questions 
relating thereto or had independently verified such information or data.

In the course of its evaluations, NSAI prepared, for all of the audited properties, its own estimates of the Company's proved 
reserves and the pre-tax present values of such reserves discounted at ten percent. NSAI reviewed its audit differences with the 
Company, and, in a number of cases, held meetings with the Company to review additional reserves work performed by the 
Company's technical teams and any updated performance data related to the proved reserve differences. Such data was incorporated, 
as appropriate, by both parties into the proved reserve estimates. NSAI's estimates, including any adjustments resulting from 
additional data, of those proved reserves and the pre-tax present value of such reserves discounted at ten percent did not differ 
from Pioneer's estimates by more than ten percent in the aggregate. However, when compared on a lease-by-lease, field-by-field 
or area-by-area basis, some of the Company's estimates were greater than those of the reserve auditors and some were less than 
the estimates of the reserve auditors. When such differences do not exceed ten percent in the aggregate and NSAI is satisfied that 
the proved reserves and pre-tax present values of such reserves discounted at ten percent are reasonable and that its audit objectives 
have been met, NSAI will issue an unqualified audit opinion. Remaining differences are not resolved due to the limited cost benefit 
of continuing such analyses by the Company and the reserve auditors. At the conclusion of the audit process, it was NSAI's opinion, 
as set forth in its audit letter, which is included as an exhibit to this Report, that Pioneer's estimates of the Company's proved oil 
and gas reserves and associated pre-tax present values discounted at ten percent are, in the aggregate, reasonable and have been

prepared in accordance with the "Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information" 
promulgated by the SPE.

See "Item 1A. Risk Factors," "Critical Accounting Estimates" in "Item 7. Management's Discussion and Analysis and Results 
of Operations" and "Item 8. Financial Statements and Supplementary Data" for additional discussions regarding proved reserves 
and their related cash flows.

Qualifications of reserves preparers and auditors. Corporate Reserves is staffed by petroleum engineers with extensive 
industry experience and is managed by the Vice President of Corporate Reserves, the technical person that is primarily responsible 
for overseeing the Company's reserves estimates. These individuals meet the professional qualifications of reserves estimators

agencies. NSAI was founded in 1961 and performs consulting petroleum engineering services under Texas Board of Professional 
Engineers Registration No. F-2699. The technical person primarily responsible for auditing the Company's reserves estimates has 
been a practicing consulting petroleum engineer at NSAI since 1983 and has over 35 years of practical experience in petroleum 
engineering, including over 33 years of experience in the estimation and evaluation of proved reserves. He graduated with a 
Bachelor  of  Science  degree  in  Chemical  Engineering  in  1978  and  meets  or  exceeds  the  education,  training  and  experience 
requirements  set  forth  in  the  "Standards  Pertaining  to  the  Estimating  and Auditing  of  Oil  and  Gas  Reserves  Information" 
promulgated by the board of directors of the SPE.

Administration degree and at the time of the reserves audit he met or exceeded the education, training and experience requirements 
set forth in the "Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information" promulgated by the 
board of directors of the SPE.

Technologies  used  in  reserves  estimates.  Proved  undeveloped  reserves  include  those  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 
completion. Undeveloped reserves may be classified as proved reserves on undrilled acreage directly offsetting development areas 
that are reasonably certain of production when drilled, or where reliable technology provides reasonable certainty of economic 
producibility. Undrilled locations may be classified as having undeveloped proved reserves only if an ability and intent has been 
established to drill the reserves within five years, unless specific circumstances justify a longer time period.

In the context of reserves estimations, reasonable certainty means a high degree of confidence that the quantities will be 
recovered and reliable technology means a grouping of one or more technologies (including computational methods) that has been 
field-tested and has been demonstrated to provide reasonable certain results with consistency and repeatability in the formation 
being evaluated or in an analogous formation. In estimating proved reserves, the Company uses several different traditional methods 
such as performance-based methods, volumetric-based methods and analogy with similar properties. In addition, the Company 
utilizes additional technical analysis such as seismic interpretation, wireline formation tests, geophysical logs and core data to 
provide  incremental  support  for  more  complex  reservoirs.  Information  from  this  incremental  support  is  combined  with  the 
traditional technologies outlined above to enhance the certainty of the Company's proved reserve estimates.

Permian Basin

Spraberry field. The Spraberry field was discovered in 1949, encompasses eight counties in West Texas and the Company 
believes it is the largest oil field in the United States.  The field is approximately 150 miles long and 75 miles wide at its widest 
point. The oil produced is West Texas Intermediate Sweet, and the gas produced is casinghead gas with an average energy content 
of 1,400 BTU. The oil and gas are produced primarily from six formations, the upper and lower Spraberry, the Dean, the Wolfcamp, 
the Strawn and the Atoka, at depths ranging from 6,700 feet to 11,300 feet. The Company believes the Spraberry and Wolfcamp 
formations offer excellent horizontal drilling opportunities to grow oil and gas production because of the significant resource in 
place  and  numerous  undeveloped  drilling  locations. The  Company  expects  to  improve  the  incremental  recovery  rates  in  the 
Spraberry field through horizontal, infill and deeper formation drilling while containing operating expenses and drilling costs 
through economies of scale and vertical integration of field services.

During 2013, the Company drilled 502 wells in the Spraberry field and its total acreage position now approximates 823,000 
gross acres (717,000 net acres).  The Company currently has 29 rigs operating in the Spraberry field, of which 11 are drilling 
vertical wells and 18 are drilling horizontal wells, and has plans to add an additional six horizontal drilling rigs by the end of the 
first quarter of 2014.  During 2014, the Company expects to drill approximately 200 vertical wells and 255 horizontal wells, with 
the horizontal wells being principally drilled in the Wolfcamp Shale horizon. The Company expects to spend $2.4 billion of drilling 
capital in the Spraberry field during 2014.

The Company believes it has significant resource potential within its acreage based on its extensive geologic data covering 
the Spraberry and Wolfcamp A, B, C and D intervals and its drilling results to-date. During 2013, the Company completed 21 
wells in the northern portion of the play and 100 horizontal wells in the southern portion of the play. In 2014, the Company expects 
to drill 140 horizontal wells in the northern portion of the play and 115 horizontal wells in the southern portion of the play. 

During 2013, the Company initiated horizontal Wolfcamp Shale drilling activities in the northern portion of its Spraberry 
acreage position to delineate the area. Wells drilled in the northern portion of the play were expected to benefit from greater original 
oil in place and higher reservoir pressures associated with deeper drilling depths. During 2013, the Company placed on production 
nine Wolfcamp B interval wells, four Wolfcamp D interval wells, five Lower Spraberry Shale interval wells, two Jo Mill Shale 
interval wells and one Wolfcamp A interval well with encouraging results. The Company’s drilling is currently focused in Midland, 
Martin, Glasscock and Andrews counties. The wells in these areas are expected to be drilled on three-well pads to gain efficiencies; 
therefore, the wells will not be completed until after the last well on each pad is drilled and, accordingly, production from these 
wells is not expected until all wells on the pad are ready to produce. With the addition of drilling rigs during the first quarter of 
2014, combined with the effects of pad drilling, the Company expects production growth to be weighted towards the second half 
of 2014. 

The Company continues to drill vertically to deeper intervals in the Spraberry field below the Wolfcamp interval, including 
the Strawn and Atoka intervals.  The 2013 drilling program reflected 90 percent of the vertical wells being deepened below the 
Wolfcamp interval. The Company expects to drill approximately 200 vertical wells targeting deeper intervals during 2014.  These 
wells are also being drilled to meet continuous drilling obligations.

PIONEER NATURAL RESOURCES COMPANY

In January 2013, the Company signed an agreement with Sinochem, an unaffiliated third party, to sell 40 percent of Pioneer's 
interest in 207,000 net acres leased by the Company in the horizontal Wolfcamp Shale play in the southern portion of the Spraberry 
field for consideration of $1.8 billion. In May 2013, the Company completed the sale to Sinochem for net cash proceeds of $623.8 
million, resulting in a 2013 gain of $181.3 million related to the unproved property interests conveyed to Sinochem. Sinochem is 
paying the remaining $1.2 billion of the transaction price by carrying 75 percent of Pioneer's portion of ongoing drilling and 
facilities costs attributable to the Company's joint operations with Sinochem in the horizontal Wolfcamp Shale play.  Associated 
with the closing of the joint venture transaction, the Company conveyed a 40 percent interest in the producing horizontal Wolfcamp 
Shale wells in the joint venture area.

The Company plans to drill 115 horizontal wells during 2014 in the joint interest area. The Company drilled 100 horizontal 
Wolfcamp Shale wells during 2013 and had capital expenditures of $454.1 million in 2013. The 2014 drilling program will be 
focused on drilling in the higher return areas in northern Upton and Reagan counties, with approximately two-thirds of the wells 
being completed in the Wolfcamp B interval and the remainder being a mix of Wolfcamp A, C and D interval wells. 

Sinochem also elected to participate in certain vertical wells that were drilled in the joint interest area after the December 
1, 2012 effective date and received its share of production and costs from the Wolfcamp and deeper horizons based on the reserve 
contribution from the Wolfcamp and deeper intervals relative to reserves from all completed intervals. Pioneer's and Sinochem's 
participation in vertical wells is based on each party's interest without any drilling carry applied.  Pioneer retained 100 percent of 
its vertical production in the joint interest area for wells drilled before the December 1, 2012 effective date.  Pioneer also retained 
its current working interests in all horizons shallower than the Wolfcamp horizon and continues as operator of the properties in 
the joint interest area.  

The  Company  continues  to  benefit  from  its  integrated  services  to  control  drilling  and  operating  costs  and  support  the 
execution of its drilling and production activities in the Spraberry field.  The Company owns 15 vertical drilling rigs and is currently 
utilizing seven Company-owned fracture stimulation fleets totaling approximately 170,000 horsepower in the Spraberry field (see 
Note C of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for 
additional information about the Company's plan to sell its vertical drilling rig business). To support its growing operations, the 
Company also owns other field service equipment, including pulling units, fracture stimulation tanks, water transport trucks, hot 
oilers, blowout preventers, construction equipment and fishing tools. In addition, Premier Silica (the Company's wholly-owned 
sand mining subsidiary) is supplying brown sand for proppant, which is being used to fracture stimulate vertical and horizontal 
wells in the Spraberry and Wolfcamp Shale intervals.

Mid-Continent

Hugoton field. The Hugoton field in southwest Kansas is one of the largest producing gas fields in the continental United 
States. The gas is produced from the Chase and Council Grove formations at depths ranging from 2,700 feet to 3,000 feet. The 
Company's Hugoton properties are located on 268,000 gross acres (235,000 net acres), covering approximately 400 square miles. 
The Company has working interests in approximately 1,200 wells in the Hugoton field, approximately 1,000 of which it operates. 

The  Company  operates  substantially  all  of  the  gathering  and  processing  facilities,  including  the  Satanta  plant,  which 
processes the production from the Hugoton field. In January 2011, the Company sold a 49 percent interest in the Satanta plant to 
an unaffiliated third party for the third party's commitment to dedicate gas volumes to the Satanta plant.  This agreement has 
increased the Satanta plant's processing volumes and is expected to increase its economic longevity.  The Company is also exploring 
opportunities to process other gas production in the Hugoton area at the Satanta plant. By maintaining operatorship of the gathering 
and processing facilities, the Company is able to control the production, gathering, processing and sale of its Hugoton field gas 
and NGL production.  

West Panhandle field. The West Panhandle properties are located in the panhandle region of Texas. These stable, long-
lived reserves are attributable to the Red Cave, Brown Dolomite, Granite Wash and fractured Granite formations at depths no 
greater than 3,500 feet. The Company's gas has an average energy content of 1,365 BTU and is produced from approximately 700 
wells on more than 246,000 gross acres (239,000 net acres) covering over 375 square miles. The Company controls 100 percent 
of the wells, production equipment, gathering system and the Fain gas processing plant for the field. As this field is characterized 
by very low reservoir pressure, Pioneer continually works to improve compressor and gathering system efficiency.

Raton Basin

The Raton Basin properties are located in the southeast portion of Colorado. The Company owns 198,000 gross acres 
(178,000 net acres) in the center of the Raton Basin and produces CBM gas from the coal seams in the Vermejo and Raton formations 
from approximately 2,300 wells. The Company owns the majority of the well servicing and fracture stimulation equipment that 
it utilizes in the Raton field, allowing it to control costs and ensure availability. See Note D of Notes to Consolidated Financial

Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information about the impairment 
charge recorded during 2013 to reduce the carrying value of the Company's gas properties in the Raton field. 

South Texas Eagle Ford Shale

The Company's drilling activities in the South Texas area during 2013 continued to be primarily focused on delineation and 
development of Pioneer's substantial acreage position in the Eagle Ford Shale play. The 2013 drilling program was focused on 
liquids-rich drilling, with no wells drilled in dry gas acreage.

The Company completed 132 horizontal Eagle Ford Shale wells during 2013, all of which were successful, with average 
lateral lengths of 5,300 feet and, on average, 15-stage fracture stimulations. Additionally, the Company completed its first successful 
Upper Eagle Ford Shale well and estimates that approximately 25 percent of the Company's acreage is prospective for this interval 
in the Eagle Ford Shale play.  The Company plans to spend $545 million of drilling capital in 2014 to drill approximately 110 
Eagle Ford Shale wells.  The Company has been using two Pioneer-owned fracture stimulation fleets during 2013 in the Eagle 
Ford Shale area and plans to continue that usage in 2014.

The  Company's  drilling  operations  in  the  Eagle  Ford  Shale  continue  to  focus  on  improving  drilling  efficiencies.   The 
Company has added approximately 300 drilling locations in the liquids-rich area of the play as a result of downspacing from 1,000 
feet between wells (120-acre spacing) to 500 feet (60-acre spacing) between wells. Further downspacing and staggered testing to 
175 feet between wells is underway in the liquids-rich areas where the 500-foot spacing was successful.  Some areas will include 
testing of the Lower Eagle Ford Shale interval only, while others will include a combination of the Lower and Upper intervals.  
Early results from the initial 300-foot downspacing and staggered test in the Lower Eagle Ford Shale continue to be encouraging 
with five downspaced wells performing consistently with offset 500-foot spaced wells. The number of wells drilled from pads, as 
opposed to single-well locations, increased from about 45 percent of the Eagle Ford Shale wells during 2012 to about 80 percent 
in 2013, reflecting that most of the Company's acreage is now held by production. Pad drilling saves the Company a significant 
amount of capital costs per well, as compared to single-well location drilling. Pad sizes generally range from two wells to six 
wells.  In 2014, most Eagle Ford Shale wells will be drilled utilizing three-well and four-well pads. None of the wells are completed 
until all of the wells on a pad are drilled.  Therefore, the time between when the first well on a pad is spud and when the pad is 
placed on production is dependent on how many wells are drilled from the pad.

Over the past two years, the Company has been testing the use of lower-cost white sand instead of ceramic proppant to 
fracture stimulate wells drilled in shallower areas of the field. The Company is expanding the use of white sand proppant to deeper 
areas of the field to further define its performance limits. Early well performance has been similar to direct offset ceramic-stimulated 
wells. The Company fracture stimulated 100 wells with white sand proppant during 2013, with significant capital savings per well.  
The Company is continuing to monitor the performance of these wells and expects that the majority of its 2014 drilling program 
in the Eagle Ford Shale area will use lower-cost white sand proppant.

During June 2010, the Company entered into an Eagle Ford Shale joint venture transaction.  Pursuant to the transaction, 
the Company entered into a purchase and sale agreement to sell 45 percent of its Eagle Ford Shale proved and unproved oil and 
gas properties to an unaffiliated third party for $212.0 million of cash proceeds. Under the terms of the transaction, the purchaser 
also paid a 75 percent carry obligation of $886.8 million to cover a portion of the Company's share of exploration, drilling and 
completion costs attributable to the Eagle Ford Shale assets during the period from June 2010 through December 2012. As of 
December 31, 2012, the purchaser's carry obligation was satisfied. 

The Company owns a 50.1 percent member interest in EFS Midstream LLC ("EFS Midstream"), an entity formed by the 
Company to own and operate gas and liquids gathering, treating and transportation assets in the Eagle Ford Shale play.  The 
Company does not have control of EFS Midstream and accounts for its investment in EFS Midstream under the equity method of 
accounting for investments in unconsolidated affiliates. EFS Midstream is obligated to construct midstream assets in the Eagle 
Ford Shale area. The majority of the construction of the midstream assets has been completed. Eleven of the 13 planned central 
gathering plants were completed as of December 31, 2013. EFS Midstream is providing gathering, treating and transportation 
services for the Company during a 20-year contractual term.  During 2011, EFS Midstream entered into a $300 million, five-year 
revolving credit facility that is available to fund infrastructure investments, distributions or working capital needs to the extent 
such uses exceed EFS Midstream's operating cash flows.

Barnett Shale

During the fourth quarter of 2013, the Company committed to a plan to divest of its net assets in the Barnett Shale field in 
North Texas. The plan is expected to result in the sale of the Barnett Shale net assets during 2014. The Company classified the 
Barnett Shale field assets and liabilities as held for sale in the Company's accompanying consolidated balance sheet as of December 
31, 2013.  Associated with the plan to sell the Barnett Shale field, the Company recorded a noncash impairment charge of $189.5 
million during December 2013 to reduce the carrying value of the Barnett Shale net assets to their estimated fair value less costs

to sell. Historical results of operations from the Company's Barnett Shale field, and the related impairment loss, are reported as 
discontinued operations, net of tax in the Company's accompanying consolidated statements of operations.

See Note C of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary 

Data" for additional information about the Company's plan to sell its Barnett Shale assets.

Alaska

During the fourth quarter of 2013, the Company committed to a plan to sell 100 percent of the capital stock in Pioneer 
Alaska, representing all the Company's net assets in Alaska including the Company's 70 percent working interest in the Oooguruk 
project.  The  sale  of  Pioneer Alaska  continues  to  be  subject  to  ongoing  negotiations  and  certain  other  conditions,  such  as 
governmental approvals and buyer's arrangement of financing.  The assets and liabilities of Pioneer Alaska are classified as held 
for sale in the Company's accompanying consolidated balance sheet as of December 31, 2013. Associated with the planned sale 
of Pioneer Alaska, the Company recorded a noncash impairment charge of $539.8 million during December 2013 to reduce the 
carrying value of the Pioneer Alaska assets to their estimated fair value less costs to sell of $350.6 million. Pioneer Alaska's 
historical results of operations, and the related impairment loss, are reported as discontinued operations, net of tax in the Company's 
accompanying consolidated statements of operations.

See  Notes  C  and  F  of  Notes  to  Consolidated  Financial  Statements  included  in  "Item  8.  Financial  Statements  and 
Supplementary Data" for additional information about the Company's planned divestiture and exploration projects in Alaska, 
respectively.

The  Company's  plans  to  sell  the  Barnett  Shale  net  assets  and  Pioneer Alaska  are  in  differing  stages  of  marketing  and 

negotiation.  No assurance can be given that the sales will be completed in accordance with the Company's plans. 

International

During August 2012 and February 2011, the Company completed the sales of Pioneer South Africa and Pioneer Tunisia, 
respectively, to different unaffiliated third parties.  See Note C of Notes to Consolidated Financial Statements included in "Item 
8. Financial Statements and Supplementary Data" for information regarding the sale of Pioneer South Africa and Pioneer Tunisia. 
As a result of these sales, the Company no longer has operations outside the United States.

Selected Oil and Gas Information

The following tables set forth selected oil and gas information for the Company as of and for each of the years ended 
December 31, 2013, 2012 and 2011. Because of normal production declines, increased or decreased drilling activities and the 
effects of acquisitions or divestitures, the historical information presented below should not be interpreted as being indicative of 
future results.

Production, price and cost data. The price that the Company receives for the oil and gas it produces is largely a function 
of market supply and demand. Demand is affected by general economic conditions, weather and other seasonal conditions, including 
hurricanes and tropical storms. Over or under supply of oil or gas can result in substantial price volatility. Historically, commodity 
prices have been volatile and the Company expects that volatility to continue in the future. A substantial or extended decline in 
oil  or  gas  prices  or  poor  drilling  results  could  have  a  material  adverse  effect  on  the  Company's  financial  position,  results  of 
operations, cash flows, quantities of oil and gas reserves that may be economically produced and the Company's ability to access 
capital markets.

The following tables set forth production, price and cost data with respect to the Company's properties for 2013, 2012 and 
2011. These amounts represent the Company's historical results from operations without making pro forma adjustments for any 
acquisitions, divestitures or drilling activity that occurred during the respective years. The production amounts will not match the 
proved  reserve volume tables in the "Unaudited Supplementary Information" section included in "Item 8. Financial Statements 
and Supplementary Data" because field fuel volumes are included in the proved reserve volume tables.

ITEM 7.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS

Financial and Operating Performance

Pioneer's financial and operating performance for 2013 included the following highlights:

• 

Net loss attributable to common stockholders was $838.4 million ($6.16 per diluted share) for the year ended December 
31, 2013, as compared to net income attributable to common stockholders of $192.3 million ($1.50 per diluted share) in 
2012. The $1.0 billion decrease in net income attributable to common stockholders is primarily comprised of an $897.0 
million decrease in income from continuing operations and a $145.4 million increase in loss from discontinued operations, 
net of tax.  

The primary components of the decrease in net income from continuing operations include:

• 

• 

• 

• 

• 

• 

• 

• 

• 

a $1.5 billion impairment charge to reduce the carrying value of the Company’s Raton gas field assets based on 
reductions in management's long-term gas price outlook (see Note D of Notes to Consolidated Financial Statements 
included in "Item 8. Financial Statements and Supplementary Data" and "Results of Operations" below);

a $326.2 million decrease in net derivative gains, primarily as a result of changes in forward commodity prices and 
changes in the Company's portfolio of derivatives;  

a $79.1 million increase in total oil and gas production costs and production and ad valorem taxes, primarily due to 
a 12 percent increase in sales volumes; 

a $198.8 million increase in DD&A expense, primarily attributable to the aforementioned increase in sales volumes 
coupled with a decrease in Spraberry field proved undeveloped reserves as a result of removing vertical well locations 
that are no longer expected to be drilled as the Company shifts its capital resources to higher-rate-of-return horizontal 
drilling (see Supplementary Information included in "Item 8. Financial Statements and Supplementary Data");

a $51.7 million increase in general and administrative expenses primarily due to growth in employee headcount in 
support of the Company's capital expansion initiatives, performance-related compensation expense and higher stock-
based compensation expense associated with cash-settled restricted stock awards, which are classified as liabilities, 
as a result of increases in the market value of the Company's common stock; and

a $23.2 million increase in other expense, primarily due to increases in impairment of inventory and other assets; 
partially offset by

a $580.4 million increase in oil and gas revenues as a result of a 12 percent increase in total sales volumes and a 10 
percent increase in average commodity prices received per BOE;

a $502.3 million decrease in income tax provision due to the decline in income from continuing operations before 
income taxes;

a $163.1 million increase in gain on disposition of assets, primarily due to the gain recorded on the Company's sale 
of a 40 percent interest in the Company's horizontal Wolfcamp Shale play in the southern portion of the Spraberry 
field in West Texas to Sinochem; and

• 

a $20.5 million decrease in interest expense, primarily due to a decline in outstanding borrowings.

The primary components of the increase in the loss from discontinued operations, net of tax, include:

• 

• 

• 

a $196.7 million increase in impairment provisions associated with the planned sales of Pioneer Alaska and the 
Company's Barnett Shale field assets ($729.3 million) as compared to the 2012 impairment of Barnett Shale field 
assets included in discontinued operations ($532.6 million); and

a $32.0 million decrease in net gains on sales of portions of the Company's discontinued operations in the Barnett 
Shale, Alaska and South Africa assets; partially offset by 

a $68.4 million increase in income tax benefit. 

During December 2013, the Company committed to a plan to sell Pioneer Alaska and the Company's Barnett Shale 
field assets.  In accordance with GAAP, the Company has classified Pioneer Alaska and the Barnett Shale field assets and 
liabilities as discontinued operations held for sale in the Company's accompanying consolidated balance sheet as of December 
31, 2013, and has recast Pioneer Alaska and the Barnett Shale field asset's results of operations as loss from discontinued 
operations, net of associated income taxes, in the accompanying consolidated statements of operations included in "Item 
8. Financial Statements and Supplementary Data."  Loss from discontinued operations, net of tax for the year ended December 
31, 2013 includes (i) recognized noncash impairment charges totaling $729.3 million representing adjustments to reduce 
the carrying values of Pioneer Alaska and the Company's Barnett Shale field assets to their estimated fair values, partially 
offset by (ii) the results of discontinued operations (see Note C of Notes to Consolidated Financial Statements included in 
"Item 8. Financial Statements and Supplementary Data" for more information about the Company's discontinued operations);

Daily sales volumes from continuing operations increased on a BOE basis by 12 percent to 161,456 BOEPD during 2013, 
as compared to 143,939 BOEPD during 2012, primarily due to the success of the Company's drilling programs;

Average reported oil and gas prices from continuing operations increased during 2013 to $92.62 per BBL and $3.43 per 
MCF, respectively, as compared to respective average reported prices of $90.67 per BBL and $2.60 per MCF during 2012.  
Average reported NGL prices from continuing operations decreased during 2013 to $30.24 per BBL, as compared to an 
average reported price of $34.04 per BBL during 2012;  

Average oil and gas production costs per BOE from continuing operations decreased during 2013 to $10.43 as compared 
to per BOE costs of $10.59 during 2012, primarily due to a decrease in net natural gas plant charges as a result of higher 
gas prices being realized on third-party volumes that are retained as processing fees in Company-owned facilities, partially 
offset by higher third-party transportation charges incurred on increasing sales volumes in the Eagle Ford Shale field.  See 
"Results of Operations" below for more information about changes in production costs;

Net cash provided by operating activities increased by $307.7 million, or 17 percent, to $2.1 billion for 2013, as compared 
to $1.8 billion during 2012, primarily due to the increases in oil and gas sales volumes and prices, partially offset by a 
$227.6 million decrease in cash receipts on settled derivative instruments; and

As of December 31, 2013, the Company's net debt to book capitalization declined to 25 percent, as compared to 37 percent 
as of December 31, 2012, primarily due to (i) the February 2013 issuance of 10.35 million shares of the Company's common 
stock for $1.3 billion of cash proceeds, net of associated underwriting and offering expenses, and (ii) the May 2013 completion 
of the sale of a 40 percent interest in 207,000 net acres leased by the Company in the horizontal Wolfcamp Shale play in 
the southern portion of the Spraberry field in West Texas for $623.8 million of cash proceeds. The Company utilized a 
portion of the proceeds from these items to reduce long-term debt by $1.1 billion during 2013 and increase cash and cash 
equivalents by $163.3 million.  The long-term debt reduction during 2013 included (i) the conversion of the Company's 
2.875% Convertible Senior Notes (the "Convertible Senior Notes"), (ii) the repayment and termination of Pioneer Southwest's 
credit facility and (iii) the repayment of all amounts outstanding on the Company's credit facility.  

First Quarter 2014 Outlook

Based on current estimates, the Company expects that first quarter 2014 production will average 166,000 to 171,000 BOEPD.

First quarter production costs (including production and ad valorem taxes and transportation costs) are expected to average 
$13.50 to $15.50 per BOE, based on current NYMEX strip prices for oil and gas. DD&A expense is expected to average $13.50 
to $15.50 per BOE.

Total exploration and abandonment expense for the quarter is expected to be $25 million to $35 million. General and 
administrative expense is expected to be $70 million to $75 million. Interest expense is expected to be $44 million to $49 million, 
and other expense is expected to be $25 million to $35 million. Accretion of discount on asset retirement obligations is expected 
to be $3 million to $5 million.

The Company's first quarter effective income tax rate is expected to range from 35 percent to 40 percent, assuming current 
capital spending plans and no significant derivative MTM changes in the Company's derivative position. Cash income taxes are 
expected to be $5 million to $10 million and are primarily attributable to federal alternative minimum tax and state taxes.

2014 Capital Budget

Pioneer's capital program for 2014 totals $3.3 billion, consisting of $3.0 billion for drilling operations, including budgeted 
land capital for existing assets, and $285 million for other property and equipment. The 2014 budget excludes acquisitions, asset 
retirement obligations, capitalized interest, geological and geophysical general and administrative expense and capital expenditures 
associated with Pioneer Alaska and Barnett Shale field assets prior to their sale.

The 2014 drilling capital of $3.0 billion continues to be focused on oil- and liquids-rich drilling, with 97 percent of the 
capital allocated to the Spraberry field and the Eagle Ford Shale play. Following is a breakdown of the forecasted spending by 
asset area:

• 

Spraberry field - $2.4 billion, including (i) $205 million for drilling and facilities capital in the southern Wolfcamp 
joint interest area and (ii) $2.2 billion of capital in the northern Spraberry/Wolfcamp acreage, which includes $1.2 
billion of horizontal drilling capital, $440 million of vertical drilling capital, $400 million for infrastructure, land and 
science and $100 million for gas processing facilities;

•  Eagle Ford Shale – $545 million, including $480 million of horizontal drilling capital and $65 million for infrastructure 

and land; and

47

PIONEER NATURAL RESOURCES COMPANY

•  Other spending – $100 million for other existing assets.

Pioneer's budgeted expenditures for other property and equipment in 2014 include:

•  Buildings and other facilities – $160 million;
•  Vertical integration capital – $100 million; and 
•  Vehicles and other equipment – $25 million.

  The 2014 capital budget is expected to be funded from a combination of cash and cash equivalents, operating cash flow, 
proceeds from the sale of assets held for sale or from the sale of other nonstrategic assets and, if necessary, borrowings under the 
Company's credit facility.

Acquisitions

During 2013, 2012 and 2011, the Company spent $76.0 million, $157.5 million and $131.9 million, respectively, to acquire 
primarily  undeveloped  acreage  for  future  exploitation  and  exploration  activities.  The  2013  and  2012  acquisitions  primarily 
increased the Company's acreage positions in the West Texas Spraberry field.  The 2011 acquisitions primarily increased the 
Company's acreage positions in the South Texas Eagle Ford Shale play, Barnett Shale play and West Texas Spraberry field. During 
2013, the Company completed the acquisition of all of the outstanding common units of Pioneer Southwest not already owned by 
the Company in exchange for 0.2325 of a share of common stock of the Company per Pioneer Southwest common unit. Additionally, 
in 2012, the Company acquired Premier Silica for $297.1 million. See Note C of Notes to Consolidated Financial Statements 
included in "Item 8. Financial Statements and Supplementary Data" for additional information about the Company's acquisitions.

Divestitures and Discontinued Operations

Alaska.  During the fourth quarter of 2013, the Company committed to a plan to sell 100 percent of the capital stock in 
Pioneer Alaska. The sale of Pioneer Alaska continues to be subject to ongoing negotiations and certain other conditions, such as 
governmental approvals and buyer's arrangement of financing. Associated with the planned sale of Pioneer Alaska, the Company 
recorded a noncash impairment charge of $539.8 million in discontinued operations during December 2013 to reduce the carrying 
value of Pioneer Alaska to its estimated fair value less costs to sell of $350.6 million. The Company has classified Pioneer Alaska 
assets and liabilities as held for sale in the accompanying consolidated balance sheet as of December 31, 2013 and has reported 
Pioneer Alaska's historical results of operations, and the related impairment loss, as discontinued operations, net of tax in the 
Company's accompanying consolidated statements of operations.

Barnett Shale.   During the fourth quarter of 2013, the Company committed to a plan to divest of its net assets in the Barnett 
Shale field in North Texas. The plan is expected to result in the sale of the Company's Barnett Shale net assets during 2014.  The 
Company has classified its Barnett Shale field assets and liabilities as held for sale in the accompanying consolidated balance 
sheet as of December 31, 2013 and has reported the Company's Barnett Shale field historical results of operations, and the related 
impairment loss, as discontinued operations, net of tax in the Company's accompanying consolidated statements of operations.

 Associated with the plan to sell its net assets in the Barnett Shale field, the Company recorded a noncash impairment charge 
of $189.5 million in discontinued operations during December 2013 to reduce the carrying value of its net assets in the Barnett 
Shale to their estimated fair value less costs to sell.  Also included in discontinued operations in 2013 is the sale of the Company's 
interest in certain proved and unproved oil and gas properties in the Barnett Shale field for net cash proceeds of $33.8 million, 
which resulted in a gain of $8.7 million on the unproved properties sold.

Sendero. During December 2013, the Company committed to a plan to sell its majority interest in Sendero (the Company's 
vertical drilling rig subsidiary) to Sendero's minority interest owner for $31.0 million, subject to negotiating a definitive sales 
agreement and the buyer completing its financing arrangements. The Company classified these assets and liabilities as held for 
sale in the Company's accompanying consolidated balance sheet as of December 31, 2013.  

The Company's plans to sell Pioneer Alaska, the Barnett Shale net assets and Sendero are in various stages of marketing 

or negotiation.  No assurance can be given that the sales will be completed in accordance with the Company's plans. 

Southern Wolfcamp.  In January 2013, the Company signed an agreement with Sinochem to sell 40 percent of Pioneer's 
interest in 207,000 net acres leased by the Company in the horizontal Wolfcamp Shale play in the southern portion of the Spraberry 
field for total consideration of $1.8 billion.  In May 2013, the Company completed the sale to Sinochem for net cash proceeds of 
$623.8 million, resulting in a gain of $181.3 million.  Sinochem is paying the remaining $1.2 billion of the transaction price by 
carrying 75 percent of Pioneer's portion of ongoing drilling and facilities costs attributable to the Company's joint operations with 
Sinochem in the horizontal Wolfcamp Shale play.

PIONEER NATURAL RESOURCES COMPANY

Pioneer South Africa. During December 2011, the Company committed to a plan to sell Pioneer South Africa.  During the 
first quarter of 2012, the Company agreed to sell Pioneer South Africa to an unaffiliated third party, effective January 1, 2012, for 
$60.0 million of cash proceeds before normal closing and other adjustments, and the buyer's assumption of certain liabilities of 
the Company's South Africa subsidiaries. In August 2012, the Company completed the sale of Pioneer South Africa for net cash 
proceeds of $15.9 million, including normal closing adjustments for cash revenues and costs and expenses from the effective date 
through the date of the sale, resulting in a gain of $28.6 million.  Pioneer South Africa's historical results of operations, and the 
related gain recorded on the disposition of Pioneer South Africa, are reported as discontinued operations, net of tax in the Company's 
accompanying consolidated statements of operations.

Pioneer Tunisia. During December 2010, the Company committed to a plan to sell Pioneer Tunisia.  In February 2011, the 
Company sold its share holdings in Pioneer Tunisia for cash proceeds of $802.5 million, excluding cash and cash equivalents sold, 
resulting in a gain of $645.2 million. Pioneer Tunisia's historical results of operations, and the related gain recorded on the disposition 
of Pioneer Tunisia, are reported as discontinued operations, net of tax in the Company's accompanying consolidated statements 
of operations.

See Note C of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary 

Data" for additional information about the Company's divestitures and discontinued operations.

Results of Operations

Oil and gas revenues. Oil and gas revenues from continuing operations totaled $3.2 billion, $2.6 billion and $2.1 billion 

during 2013, 2012 and 2011, respectively.

The increase in 2013 oil and gas revenues relative to 2012 is reflective of 22 percent and 20 percent increases in oil and 
NGL sales volumes, respectively, and two percent and 32 percent increases in average reported oil and gas prices, respectively.  
Partially offsetting the effects of these increases was a decline of 11 percent in average reported NGL prices.

The increase in 2012 oil and gas revenues relative to 2011 is reflective of 61 percent, 28 percent and 8 percent increases in 
oil, NGL, and gas sales volumes, respectively. Partially offsetting the effects of these production increases were declines of six 
percent, 26 percent and 33 percent in average reported oil, NGL and gas prices, respectively.  

The following table provides average daily sales volumes from continuing operations for 2013, 2012 and 2011:

Average daily BOE sales volumes from continuing operations in 2013 and 2012 increased by 12 percent and 28 percent, 
respectively, as compared to the daily sales volumes in the respective prior years, principally due to the Company's successful 
drilling programs.  In 2012, the increase in average daily BOE sales was also attributable to declines in scheduled VPP deliveries.  
All VPP production volumes were delivered as of December 31, 2012 and there are no further obligations under the VPP contracts.

Production for the year ended December 31, 2013 was negatively impacted by (i) gas processing capacity limitations in 
the Spraberry field as a result of wet gas production for the Company and other industry participants growing faster than anticipated 
and (ii) severe winter weather during the fourth quarter.  New Spraberry field gas processing facilities were completed and began 
processing gas in mid-April 2013. The gas processing capacity limitations negatively impacted sales volumes by approximately 
600 BOEPD for the year ended December 31, 2013.  Additionally, 2013 production was reduced by approximately 1,500 BOEPD, 
related to heavy icing and low temperatures during the fourth quarter primarily across Pioneer's leasehold position in the Spraberry/
Wolfcamp area that resulted in extensive power outages, facility freeze-ups, trucking curtailments and limited access to production 
and drilling facilities. All of the affected wells have since been returned to production.

Production growth for 2012, as compared to 2011, was negatively impacted by gas processing capacity limitations in the 
Spraberry field as a result of wet gas production for the Company and other industry participants growing faster than anticipated.  
The gas processing capacity limitations negatively impacted average 2012 sales volumes by approximately 1,450 BOEPD.

 ____________________
(a) 

For the years ended December 31, 2012 and 2011, the Company's average realized oil prices per BBL were $88.81 and 
$90.61, respectively, and the average realized prices per BOE for the years ended December 31, 2012 and 2011 were $48.15 
and $48.90, respectively. The average realized prices do not include the impact of transfers of the Company's deferred hedge 
gains and losses from Accumulated Other Comprehensive Income ("AOCI-Hedging") and the amortization of deferred 
VPP revenue.  During the year ended December 31, 2012 and 2011, the Company transferred $3.2 million of deferred oil 
hedge losses and $32.9 million of deferred oil hedge gains, respectively, from AOCI-Hedging to oil revenue. The 2012 
transfer  represented  all  of  the  remaining AOCI-Hedging  transfers  to  earnings.   Amortization  of  deferred VPP  revenue 
increased oil revenues by $42.1 million and $45.0 million during the years ended December 31, 2012 and 2011, respectively.  
As of December 31, 2012, all VPP production volumes had been delivered and there are no further obligations under VPP 
contracts.

Sales of purchased oil and gas. The Company periodically enters into pipeline capacity commitments in order to secure 
available oil and gas transportation capacity from the Company’s areas of production. The Company enters into oil and gas purchase 
transactions with third parties and separate sale transactions with third parties to satisfy unused pipeline capacity commitments 
and to diversify a portion of the Company's WTI oil sales to a Gulf Coast oil price. Revenues and expenses from these transactions 
are presented on a gross basis as the Company acts as a principal in the transaction by assuming the risk and rewards of ownership, 
including credit risk, of the oil and gas purchased and assuming responsibility to deliver the oil and gas volumes sold. Deficiency 
payments on excess pipeline capacity are included in other expense in the accompanying consolidated statements of operations.  
See Note N of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" 
for further information on transportation commitment charges.

Interest and other income. The Company's interest and other income from continuing operations was $17.0 million and 
$29.4 million during 2013 and 2011, respectively, and a loss of $1.0 million in 2012. The $18.0 million increase during 2013, as 
compared to 2012, is primarily attributable to a $7.1 million reduction in losses from vertical integration services, a $5.1 million 
increase in equity in earnings of EFS Midstream and $4.1 million of gains on deferred compensation plan assets. The $30.4 million 
decrease during 2012, as compared to 2011, is primarily attributable to a $27.9 million decrease in income from vertical integration 
services. See Note M of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary 
Data" for more information about the Company's interest and other income.

Derivative gains (losses), net. The Company utilizes commodity swap contracts, collar contracts and collar contracts with 
short  puts  in  order  to  (i) reduce  the  effect  of  price  volatility  on  the  commodities  the  Company  produces,  sells  or  consumes, 
(ii) support the Company's annual capital budgeting and expenditure plans and (iii) reduce commodity price risk associated with 
certain capital projects. In 2009, the Company discontinued hedge accounting on all of its then-existing derivative contracts. 
Changes in the fair value of effective cash flow hedges prior to the Company's discontinuance of hedge accounting were recorded 
as a component of AOCI – Hedging in the equity section of the Company's consolidated balance sheets, and were transferred to 
earnings during the same periods in which the hedged transactions were recognized in the Company's earnings. Since 2009, the 
Company has recognized all changes in the fair values of its derivative contracts as gains or losses in the earnings of the periods 
in which they occur. All deferred oil hedge losses were transferred from AOCI-Hedging to earnings during the year ended December 
31, 2012. Transfers of deferred hedge gains and losses associated with oil cash flow hedges from AOCI – Hedging to oil revenues 
for the years ended December 31, 2012 and 2011 resulted in a decrease of $3.2 million and an increase of $32.9 million, respectively, 
to oil revenue.

Gain (loss) on disposition of assets. The Company recorded net gains of $209.0 million and $45.9 million during 2013 and 

2012, respectively, and a net loss on the disposition of assets of $3.6 million during 2011.

During 2013, the Company's primary gains on disposition of assets included a $181.3 million gain on the sale of a 40 percent 
interest in the Company's horizontal Wolfcamp Shale play in the southern portion of the Spraberry field in West Texas to Sinochem 
and a gain of $22.4 million on the sale of the Company's interest in unproved oil and gas properties adjacent to the Company's 
West Panhandle field operations.  During 2012, the Company recorded a $42.6 million gain on the sale of a portion of its interest 

51

 
 
 
PIONEER NATURAL RESOURCES COMPANY

in an unproved oil and gas property in the Eagle Ford Shale field. During 2011, the net loss was primarily associated with losses 
on the sales of excess materials and supplies inventory, partially offset by gains on the sale of certain unproved properties. 

Oil and gas production costs. The Company's oil and gas production costs from continuing operations totaled $614.7 
million, $558.0 million and $397.0 million during 2013, 2012 and 2011, respectively. In general, lease operating expenses and 
workover expenses represent the components of oil and gas production costs over which the Company has management control, 
while third-party transportation charges represent the cost to transport volumes produced to a sales point. Net natural gas plant/
gathering charges represent the net costs to gather and process the Company's gas, reduced by net revenues earned from gathering 
and processing of third party gas in Company-owned facilities.

Total oil and gas production costs per BOE for the year ended December 31, 2013 decreased by two percent as compared 
to 2012. The decrease in production costs per BOE during 2013 is primarily reflective of a $0.44 per BOE decrease in net natural 
gas plant charges as a result of higher gas prices being realized on third-party volumes that are retained as processing fees in 
Company-owned facilities.  Partially offsetting the decrease in per BOE net natural gas plant charges was a $0.25 per BOE increase 
in third-party transportation charges, primarily associated with increasing Eagle Ford Shale sales volumes.

During 2012, total production costs per BOE increased by nine percent as compared to 2011. The increase in production 
costs per BOE during 2012 is primarily reflective of increases in lease operating expenses, third-party transportation charges and 
net natural gas plant/gathering charges.  Lease operating costs increased by $0.32 per BOE during 2012 primarily due to an increase 
in salt water disposal costs (principally comprised of water hauling fees). The $0.17 per BOE increase in third-party transportation 
charges during 2012 is primarily due to gathering, treating and transportation costs associated with increasing sales volumes from 
the Company's successful drilling program in the Eagle Ford Shale field.  Net natural gas plant charges increased by $0.38 per 
BOE during 2012 primarily due to a reduction in third-party revenues from processing third-party gas volumes in Company-owned 
facilities as a result of lower gas and NGL prices being realized on the volumes retained as a processing fee.

The following table provides the components of the Company's total production costs per BOE for 2013, 2012 and 2011:

Production and ad valorem taxes. The Company recorded production and ad valorem taxes of $201.2 million during 2013, 
as compared to $178.7 million and $139.4 million for 2012 and 2011, respectively. In general, production taxes and ad valorem 
taxes are directly related to commodity price changes; however, Texas ad valorem taxes are based upon prior year commodity 
prices, whereas production taxes are based upon current year commodity prices. Production and ad valorem taxes on a per BOE 
basis have been relatively stable since 2011. 

The following table provides the Company's production and ad valorem taxes per BOE from continuing operations and

 Depletion, depreciation and amortization expense. The Company's total DD&A expense from continuing operations 

was $907.1 million ($15.39 per BOE), $708.3 million ($13.44 per BOE), and $489.6 million ($11.96 per BOE) for 2013, 2012 
and 2011, respectively. Depletion expense on oil and gas properties, the largest component of DD&A expense, was $14.70, 
$12.82 and $11.33 per BOE during 2013, 2012 and 2011, respectively.

During 2013, the 15 percent increase in per BOE depletion expense, as compared to that of 2012, is primarily due to (i) 
capital expenditures to develop proved undeveloped locations, primarily in the Company's successful Spraberry and Eagle Ford 
Shale fields programs and (ii) a 22 percent decline in total proved reserves.  The decline in total proved reserves is primarily 

52

 
 
 
 
 
 
PIONEER NATURAL RESOURCES COMPANY

comprised of negative revisions of previous estimates to remove undeveloped vertical well locations that are no longer expected 
to be drilled as the Company shifts its planned capital expenditures to higher-rate-of-return horizontal drilling, partially offset by 
a nine percent increase in proved developed reserves. 

During 2012, the 13 percent increase in per BOE depletion expense was primarily due to (i) increased drilling expenditures 
on proved undeveloped locations, primarily in the Spraberry field and (ii) declines in proved gas reserves due to lower first-day-
of-the-month gas prices during the twelve month period ending on December 31, 2012, partially offset by (iii) the impairment 
effects of reducing carrying values of the South Texas Edwards Trend/Austin Chalk fields during 2012 and 2011, respectively (see 
the discussion below for more information on the Company's impairment charges).

Impairment of oil and gas properties and other long-lived assets. The Company recorded impairment expense in continuing 
operations  to  reduce  the  carrying  values  of  oil  and  gas  properties  by  $1.5  billion  and  $354.4  million  during  the  years  ended 
December 31, 2013 and 2011, respectively. 

The Company performs assessments of its long-lived assets to be held and used, including oil and gas properties, whenever 
events  or  circumstances  indicate  that  the  carrying  values  of  those  assets  may  not  be  recoverable.  In  order  to  perform  these 
assessments, management uses various observable and unobservable inputs, including management's outlooks for (i) commodity 
prices, (ii) production costs, (iii) capital expenditures and (iv) production, based upon current estimates of proved reserves and 
risk-adjusted probable reserves.

Management's commodity price outlooks represent longer-term outlooks that are developed based on third-party longer-
term commodity futures price outlooks as of a measurement date ("Management's Price Outlooks"). During 2013, 2012 and 2011, 
declines in Management's Price Outlooks for gas provided indications of possible impairment of the Company's predominantly 
dry gas properties in the Raton field in southeastern Colorado,  the Barnett Shale field in North Texas (classified as held for sale 
as of December 31, 2013) and the Edwards Trend and Austin Chalk fields in South Texas, respectively.  During the years ended 
December 31, 2013 and 2012, Management's Price Outlook for gas declined by 10 percent and four percent, respectively, and 
Management's Price Outlook for oil declined by seven percent for both periods.  The trend of Management's Price Outlooks by 
quarter during 2013 is as follows:

Management's gas outlook.......

$86.40

As a result of management's assessments, during 2013, 2012 and 2011, the Company recognized noncash impairment 
charges of $1.5 billion, $532.6 million and $354.4 million to reduce the carrying values of the Company's Raton field assets, the 
Company's Barnett Shale field assets (which are now classified as discontinued operations in the accompanying statements of 
operations) and the Edwards Trend/Austin Chalk field assets, respectively, to their estimated fair values.  

Declines in Management's Price Outlooks during 2013 also provided an indication that the Company's Hugoton field assets 
in southwest Kansas may have been impaired.  The Company's estimates of undiscounted future net cash flows attributable to the 
Hugoton field assets indicated that on December 31, 2013 their carrying amounts are expected to be recovered, but continue to 
be at risk for impairment if estimates of future cash flows decline.  For example, the Company estimates that the carrying value 
of the Hugoton field may become partially impaired if the average price in Management's Price Outlook for gas were to decline 
by approximately $0.30 to $0.50 per MCF.  The Company estimates that if the Hugoton field were to become impaired in a future 
period, the Company would recognize noncash impairment charges in that period that could range from $200 million to $250 
million.    

It is reasonably possible that the estimate of undiscounted future net cash flows attributable to these or other properties may 
change in the future resulting in the need to impair their carrying values. The primary factors that may affect estimates of future 
cash flows are (i) future reserve adjustments, both positive and negative, to proved reserves and appropriate risk-adjusted probable 
and possible reserves (ii) results of future drilling activities, (iii) Management's Price Outlooks and (iv) increases or decreases in 
production and capital costs associated with these fields.

See  Notes  B  and  D  of  Notes  to  Consolidated  Financial  Statements  included  in  "Item  8.  Financial  Statements  and 

Supplementary Data" for additional information about the Company's impairment assessments.

During 2013, the Company's exploration and abandonment expense was primarily attributable to $77.0 million of geological 
and geophysical costs, of which $58.0 million was geological and geophysical administrative costs; $5.9 million of dry hole 
provisions; and $15.5 million of leasehold abandonment expense, which included $14.3 million associated with the Company's 
unproved dry gas properties in the Eagle Ford Shale and other unproved property abandonments.  During 2013, the Company 
completed and evaluated 253 exploration/extension wells, 244 of which were successfully completed as discoveries.

During 2012, the Company's exploration and abandonment expense was primarily attributable to $66.9 million of geological 
and geophysical costs, of which $42.0 million was geological and geophysical administrative costs; $9.0 million of dry hole 
provisions; and $22.2 million of leasehold abandonment expense. The significant components of the Company's 2012 leasehold 
abandonment expense included $9.5 million in the Eagle Ford Shale area, $4.8 million in the Rockies area and $4.7 million in the 
Permian  Basin.    During  2012,  the  Company  completed  and  evaluated  229  exploration/extension  wells,  223  of  which  were 
successfully completed as discoveries.

During 2011, the Company's exploration and abandonment expense was primarily attributable to $48.1 million of geological 
and geophysical costs, of which $32.0 million was geological and geophysical administrative costs, and $29.7 million of leasehold 
abandonment expense.  The significant components of the Company's 2011 leasehold abandonment expense included dry gas 
unproved acreage abandonments of $9.3 million in the South Texas area and $9.1 million in the Rockies area.  During 2011, the 
Company completed and evaluated 168 exploration/extension wells, 167 of which were successfully completed as discoveries.

General and administrative expense. General and administrative expense from continuing operations totaled $295.9 million, 
$244.2 million and $190.0 million during 2013, 2012 and 2011, respectively.  The increase in 2013, as compared to 2012, is 
primarily due to increases of $42.7 million and $3.3 million in compensation and occupancy expenses, respectively, related to 
staffing increases in support of the Company's capital expansion and integrated services initiatives.  The $42.7 million increase 
in compensation expense includes a $7.6 million increase in stock-based compensation expense associated with Liability Awards, 
primarily due to increases in the market value of the Company's common stock during 2013, and an $18.9 million increase in cash 
bonus expense payable to employees as a result of the accomplishments of the Company during 2013.

The increase in general and administrative expense during 2012, as compared to 2011, was also primarily due to increases 
of $45.7 million and $4.7 million in compensation and occupancy expenses, respectively, related to staffing increases in support 
of the Company's capital expansion and integrated services initiatives. 

Accretion of discount on asset retirement obligations. Accretion of discount on asset retirement obligations from continuing 
operations was $11.9 million, $8.7 million and $7.5 million during 2013, 2012 and 2011, respectively. The 37 percent and 16 
percent increases in accretion of discount on asset retirement obligations during 2013 and 2012, respectively, are primarily due 
to additional well completions resulting from the Company's drilling activities. See Note I of Notes to Consolidated Financial 
Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information regarding the Company's 
asset retirement obligations.

Interest expense. Interest expense was $183.8 million, $204.2 million and $181.6 million during 2013, 2012 and 2011, 
respectively. The weighted average interest rate on the Company's indebtedness for the year ended December 31, 2013 was 6.5 
percent, as compared to 6.0 percent and 7.2 percent for the years ended December 31, 2012 and 2011, respectively.

The decrease in interest expense during 2013, as compared to 2012, was primarily due to a decrease in debt as a result of 
the repayment of amounts outstanding under Pioneer Southwest's credit facility and conversions of Convertible Senior Notes, and 
a decrease of $18.3 million in noncash amortization of financing fees, debt issuance discounts and deferred hedge losses.

54

 
 
 
PIONEER NATURAL RESOURCES COMPANY

The $22.6 million increase in interest expense during 2012, as compared to 2011, is primarily due to an $868.9 million 
increase in the Company's average outstanding indebtedness, partially offset the 1.2 percent decline in weighted average interest 
on indebtedness. 

See Note G of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary 

Data" for additional information about the Company's long-term debt and interest expense.

Other expenses. Other expenses from continuing operations were $137.4 million during 2013, as compared to $114.2 
million during 2012 and $63.1 million during 2011. The $23.2 million increase in other expense during 2013, as compared to 
2012, is primarily associated with (i) $25.5 million of impairment associated with the planned sale of the Company's majority 
interest in Sendero, (ii) a $30.6 million increase in inventory valuation allowances and (iii) an $8.8 million increase in contingency 
and environmental accrual adjustments, partially offset by (iv) a $23.4 million decrease in above market and idle drilling and well 
service equipment charges and (v) a $14.7 million decrease in terminated drilling rig contract charges.   

The $51.1 million increase in other expense during 2012, as compared to 2011, is primarily due to $15.7 million of contract 
rig termination fees incurred during 2012, a $15.0 million increase in unused gas transportation commitment charges and a $13.0 
million increase in above market and idle drilling and well service equipment charges, which are not chargeable to joint operations. 

See Note N of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary 

Data" for additional information regarding the Company's other expenses.

Income tax provision. The Company recognized an income tax benefit attributable to earnings from continuing operations 
of $211.8 million during 2013, as compared to income tax provisions of $290.5 million and $188.3 million during 2012 and 2011, 
respectively. The Company's effective tax rates on earnings from continuing operations, excluding income from noncontrolling 
interest, for 2013, 2012 and 2011 were 35 percent, 37 percent and 34 percent, respectively, as compared to the combined United 
States federal and state statutory rates of approximately 36 percent.

See "Critical Accounting Estimates" below and Note O of Notes to Consolidated Financial Statements included in "Item 
8.  Financial  Statements  and  Supplementary  Data"  for  additional  information  regarding  the  Company's  income  tax  rates  and 
attributes.

Income (loss) from discontinued operations, net of tax. The Company recognized a loss from discontinued operations, 
net of tax, of $449.6 million in 2013 as compared to a loss of $304.2 million for 2012 and income of $474.1 million for 2011. 
Income (loss) from discontinued operations, net of tax includes the operations of the following:

Pioneer Alaska which was placed into assets held for sale and discontinued operation in December 2013,

• 
•  The Barnett Shale field assets which were placed into assets held for sale and discontinued operation in December 

2013,
Pioneer South Africa which was placed into assets held for sale and discontinued operation in December 2011; and
Pioneer Tunisia which was placed into assets held for sale and discontinued operations in December 2010.

• 
• 

The $145.4 million increase in loss from discontinued operations, net of tax during 2013, as compared to 2012 is primarily 
attributable to the increase in impairments of net assets.  In 2013, the Company had total impairments of Pioneer Alaska and 
Barnett Shale assets of $729.3 million, compared to impairment charges of $532.6 million on Barnett Shale assets in 2012.  The 
$778.3  million  decrease  in  income  from  discontinued  operations,  net  of  tax  during  2012,  as  compared  to  2011  is  primarily 
attributable to the after tax gain on the sale of Pioneer Tunisia recorded in 2011 and the 2012 impairment of Barnett Shale field 
assets.

See Note C of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary 

Data" for additional information regarding the Company's discontinued operations.

Net income attributable to noncontrolling interest. Net income attributable to noncontrolling interests was $38.9 million, 
$50.5 million and $47.4 million for the years ended December 31, 2013, 2012 and 2011, respectively. The Company's net income 
attributable to noncontrolling interest is primarily associated with the net income of Pioneer Southwest that was allocated to limited 
partners,  through  December  17,  2013,  the  date  of  the  Pioneer  Southwest  merger.  The  $11.6  million  decrease  in  net  income 
attributable to noncontrolling interest in 2013, as compared to 2012, is primarily due to decreases in Pioneer Southwest's noncash 
derivative gains, higher production costs and higher depletion expense, partially offset by increased revenues.

The $3.1 million increase in net income attributable to noncontrolling interest in 2012, as compared to 2011, is primarily 
due to a 10 percent increase in noncontrolling interest in Pioneer Southwest during November 2011 as a result of an offering by 
Pioneer Southwest of 4.4 million common units, representing limited partnership units, of which 1.8 million common units were 

55

PIONEER NATURAL RESOURCES COMPANY

sold by the Company.  Partially offsetting the increase in noncontrolling interest in Pioneer Southwest was a $15.3 million decline 
in Pioneer Southwest's net income during 2012, as compared to 2011.  See Note B of Notes to Consolidated Financial Statements 
included in "Item 8. Financial Statements and Supplementary Data" for additional information regarding Pioneer Southwest and 
the Company's noncontrolling interest in consolidated subsidiaries' net income.

Capital Commitments, Capital Resources and Liquidity

Capital commitments. The Company's primary needs for cash are for capital expenditures and acquisition expenditures on 
oil and gas properties and related vertical integration assets and facilities, payments of contractual obligations, dividends and 
working capital obligations. Funding for these cash needs may be provided by any combination of internally-generated cash flow, 
cash and cash equivalents on hand, proceeds from the sale of nonstrategic assets or external financing sources as discussed in 
"Capital resources" below.  During 2014, the Company expects that it will be able to fund its needs for cash (excluding acquisitions, 
if any) with a combination of internally generated cash flows, cash and cash equivalents on hand, proceeds from the divestiture 
of assets held for sale, proceeds from the sale of other nonstrategic assets and, if necessary, availability under the Company's credit 
facility. Although the Company expects that these sources of funding will be adequate to fund capital expenditures and dividend 
payments and provide adequate liquidity to fund other needs, no assurances can be given that such funding sources will be adequate 
to meet the Company's future needs.

During 2014, the Company plans to continue to focus its capital spending primarily on liquids-rich drilling activities. The 
Company's  2014  capital  budget  totals  $3.3  billion  (excluding  acquisitions,  asset  retirement  obligations,  capitalized  interest, 
geological and geophysical administrative costs and capital expenditures associated with Pioneer Alaska and Barnett Shale field 
assets prior to their sale), consisting of $3.0 billion for drilling operations and $285 million for buildings, vertical integration and 
other plant and equipment additions. Based on the Company's current Management Price Outlooks, Pioneer expects its net cash 
flows from operating activities, cash and cash equivalents on hand, proceeds from the divestiture of assets held for sale, proceeds 
from other nonstrategic assets sales and, if necessary, availability under the Company's credit facility to be sufficient to fund its 
planned capital expenditures and contractual obligations.

Investing activities. Net cash used in investing activities during 2013 was $2.1 billion, as compared to net cash used in 
investing activities of $3.3 billion and $1.6 billion during 2012 and 2011, respectively.  The decrease in net cash flow used in 
investing activities during 2013, as compared to 2012, is primarily due to (i) a $615.5 million increase in proceeds from disposition 
of assets, which resulted from $623.8 million of net cash proceeds from the May 2013 sale to Sinochem of a 40 percent interest 
in the Company's horizontal Wolfcamp Shale play in the southern portion of the Spraberry field in West Texas, (ii) a $297.1 million 
decrease in payments for acquisitions due to the acquisition of Premier Silica during 2012, (iii) a $119.3 million decrease in 
additions to oil and gas properties, partially due to the drilling carry being paid by Sinochem in the southern portion of the horizontal 
Wolfcamp Shale play, (iv) a $59.7 million decrease in additions to other assets and other property and equipment and (v) a $25.1 
million distribution from EFS Midstream during December 2013. In addition to the aforementioned proceeds from disposition of 
assets, the Company's investing activities during the year ended December 31, 2013 were funded by net cash provided by operating 
activities.

 The increase in net cash flow used in investing activities during 2012, as compared to 2011, was primarily due to (i) an 
$831.1 million increase in additions to oil and gas properties associated with the Company's capital programs, (ii) a $723.5 million 
decrease in proceeds from disposition of assets (primarily attributable to the 2011 sale of Pioneer Tunisia, partially offset by 
proceeds from the sales of Pioneer South Africa and a partial interest in certain Eagle Ford Shale unproved leaseholds during 
2012) and (iii) the $297.1 million of cash used for the acquisition of Premier Silica, partially offset by (iv) an $89.6 million decrease 
in investments in EFS Midstream and (v) a $66.4 million decrease in additions to other assets and other property and equipment. 
See "Results of Operations" above and Note C of Notes to Consolidated Financial Statements included in "Item 8. Financial 
Statements and Supplementary Data" for additional information regarding asset divestitures.

Dividends/distributions. During each of the years ended December 31, 2013, 2012 and 2011, the Board declared semiannual 
dividends of $0.04 per common share. Associated therewith, the Company paid $11.1 million, $10.0 million and $9.6 million, 
respectively, of aggregate dividends. Future dividends are at the discretion of the Board, and, if declared, the Board may change 
the dividend amount based on the Company's liquidity and capital resources at the time.

During January, April, July and October of 2013, 2012 and 2011, the board of directors of the general partner of Pioneer 
Southwest declared quarterly distributions aggregating annually to $2.08, $2.07 and $2.03 per limited partner unit, respectively. 
Associated therewith, Pioneer Southwest paid aggregate distributions to noncontrolling unitholders of $35.3 million, $35.2 million 
and $25.6 million during the years ended December 31, 2013, 2012 and 2011, respectively.

Off-balance  sheet  arrangements.  From  time-to-time,  the  Company  enters  into  off-balance  sheet  arrangements  and 
transactions that can give rise to material off-balance sheet obligations of the Company. As of December 31, 2013, the material 

56

PIONEER NATURAL RESOURCES COMPANY

off-balance  sheet  arrangements  and  transactions  that  the  Company  has  entered  into  include  (i) operating  lease  agreements, 
(ii) drilling  commitments  (iii)  firm  transportation  and  fractionation  commitments,  (iv) open  purchase  commitments  and  (v) 
contractual obligations for which the ultimate settlement amounts are not fixed and determinable, such as derivative contracts that 
are  sensitive  to  future  changes  in  commodity  prices  or  interest  rates,  gathering,  treating,  fractionation  and  transportation 
commitments on uncertain volumes of future throughput, open delivery commitments and indemnification obligations following 
certain divestitures. Other than the off-balance sheet arrangements described above, the Company has no transactions, arrangements 
or other relationships with unconsolidated entities or other persons that are reasonably likely to materially affect the Company's 
liquidity or availability of or requirements for capital resources. See "Contractual obligations" below and Note J of Notes to 
Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for more information 
regarding the Company's off-balance sheet arrangements.

Contractual  obligations.  The  Company's  contractual  obligations  include  long-term  debt,  operating  leases,  drilling 
commitments (including commitments to pay day rates for drilling rigs), capital funding obligations, derivative obligations, other 
liabilities (including postretirement benefit obligations), firm transportation and fractionation commitments and minimum annual 
gathering, treating and transportation commitments.  Other joint owners in the properties operated by the Company will incur 
portions of the costs represented by these commitments.

The following table summarizes by period the payments due by the Company for contractual obligations estimated as of 

December 31, 2013:

See Note J of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary 
Data" for more information about the Company's operating leases.

(b) 

(c)  Drilling commitments represent future minimum expenditure commitments for drilling rig services and well commitments 

under contracts to which the Company was a party on December 31, 2013.

(d)  Derivative obligations represent net liabilities determined in accordance with master netting arrangements for commodity 
and interest rate derivatives that were valued as of December 31, 2013. The ultimate settlement amounts of the Company's 
derivative obligations are unknown because they are subject to continuing market risk. See "Item 7A. Quantitative and 
Qualitative Disclosures About Market Risk" and Note E of Notes to Consolidated Financial Statements included in "Item 
8. Financial Statements and Supplementary Data" for additional information regarding the Company's derivative obligations.
(e)  Open purchase commitments primarily represent expenditure commitments for inventory, materials and other property and 

(f) 

equipment ordered, but not received, as of December 31, 2013.
The Company's other liabilities represent current and noncurrent other liabilities that are comprised of postretirement benefit 
obligations, litigation and environmental contingencies, asset retirement obligations and other obligations for which neither 
the ultimate settlement amounts nor their timings can be precisely determined in advance. See Notes H, I and J of Notes to 
Consolidated  Financial  Statements  included  in  "Item  8.  Financial  Statements  and  Supplementary  Data"  for  additional 
information regarding the Company's postretirement benefit obligations, asset retirement obligations and litigation and 
environmental contingencies, respectively.

(g)  Gathering, processing and transportation commitments represent estimated fees on production throughput commitments 
and demand fees associated with volume delivery commitments of up to 50,000 BOEPD through August 2017 that are 
related to the Company's Permian Basin operations. The Company does not expect to be able to fulfill all of its short-term 
and long-term delivery obligations from projected production of available reserves; consequently, the Company plans to 

57

 
 
 
 
PIONEER NATURAL RESOURCES COMPANY

purchase third party volumes to satisfy its commitments if it is economic to do so; otherwise, it will pay demand fees for 
commitment shortfalls. See "Item 2. Properties" and Note J of Notes to Consolidated Financial Statements included in "Item 
8. Financial Statements and Supplementary Data" for additional information regarding the Company's gathering, processing 
and transportation commitments.

Capital resources. The Company's primary capital resources are cash and cash equivalents, net cash provided by operating 
activities,  proceeds  from  sales  of  joint  interests  and  nonstrategic  assets  and  proceeds  from  financing  activities  (principally 
borrowings under the Company's credit facility or issuances of debt or equity securities). If internal cash flows and cash on hand 
do not meet the Company's expectations, the Company may reduce its level of capital expenditures, and/or fund a portion of its 
capital expenditures using availability under the Company's credit facility, issue debt or equity securities or obtain capital from 
other sources, such as through sales of nonstrategic assets.

Operating activities. Net cash provided by operating activities for the years ended December 31, 2013, 2012 and 2011 was 
$2.1 billion, $1.8 billion and $1.5 billion, respectively. The increase in net cash flow provided by operating activities in 2013 was 
primarily due to an increase in oil and gas sales, partially offset by a decrease in net cash receipts from derivative settlements. The 
increase in net cash flow provided by operating activities in 2012 was primarily due to increases in oil and gas sales and net cash 
receipts from derivative settlements.

Asset divestitures.  During the fourth quarter of 2013, the Company committed to a plan to sell 100 percent of the capital 
stock in Pioneer Alaska. The sale of Pioneer Alaska continues to be subject to ongoing negotiations and certain other conditions, 
such as governmental approvals and buyer's arrangement of financing. Associated with the planned sale of Pioneer Alaska, the 
Company recorded a noncash impairment charge of $539.8 million in discontinued operations during December 2013 to reduce 
the carrying value of the Pioneer Alaska assets to their estimated fair value less costs to sell of $350.6 million. The Company has 
classified Pioneer Alaska assets and liabilities as held for sale in the accompanying consolidated balance sheet as of December 
31,  2013  and  has  reported  Pioneer Alaska's  historical  results  of  operations,  and  the  related  impairment  loss,  as  discontinued 
operations, net of tax in the Company's accompanying consolidated statements of operations.

 During the fourth quarter of 2013, the Company committed to a plan to divest of its net assets in the Barnett Shale field in 
North Texas. The plan is expected to result in the sale of the Barnett Shale net assets during 2014.  The Company has classified 
Barnett Shale assets and liabilities as held for sale in the accompanying consolidated balance sheet as of December 31, 2013 and 
has reported Barnett Shale historical results of operations, and the related impairment loss, as discontinued operations, net of tax 
in the Company's accompanying consolidated statements of operations.

 Associated with the plan to sell its net assets in the Barnett Shale field, the Company recorded a noncash impairment charge 
of $189.5 million in discontinued operations during December 2013 to reduce the carrying value of its net assets in the Barnett 
Shale field to their estimated fair value less costs to sell. See Note D for more information about the impairment of the Company's 
Barnett Shale field net assets.  Also included in discontinued operations in 2013 is the sale of the Company's interest in certain 
proved and unproved oil and gas properties in the Barnett Shale field for net cash proceeds of $33.8 million, which resulted in a 
gain of $8.7 million on the unproved properties sold.

During December 2013, the Company committed to a plan to sell its majority interest in Sendero (the Company's vertical 
drilling rig subsidiary) to Sendero's minority interest owner for $31.0 million, subject to negotiating a definitive sales agreement 
and the buyer completing its financing arrangements. The Company classified these assets and liabilities as held for sale in the 
Company's accompanying consolidated balance sheet as of December 31, 2013. 

The Company's plans to sell Pioneer Alaska, the Barnett Shale net assets and Sendero are in various stages of marketing 

or negotiation.  No assurance can be given that the sales will be completed in accordance with the Company's plans. 

In January 2013, the Company signed an agreement with Sinochem to sell 40 percent of Pioneer's interest in 207,000 net 
acres leased by the Company in the horizontal Wolfcamp Shale play in the southern portion of the Spraberry field for consideration 
of $1.8 billion.  In May 2013, the Company completed the sale to Sinochem for net cash proceeds of $623.8 million, resulting in 
a gain of $181.3 million related to the unproved property interests conveyed to Sinochem.  Sinochem is paying the remaining $1.2 
billion of the transaction price by carrying 75 percent of Pioneer's portion of ongoing drilling and facilities costs attributable to 
the Company's joint operations with Sinochem in the horizontal Wolfcamp Shale play. 

During the first quarter of 2012, the Company agreed to sell Pioneer South Africa to an unaffiliated third party for $60.0 
million of cash proceeds before normal closing and other adjustments, and the buyer's assumption of certain liabilities of the 
Company's South Africa subsidiaries.  In August 2012, the Company completed the sale of Pioneer South Africa for net cash 
proceeds of $15.9 million, including normal closing adjustments for cash revenues and costs and expenses from the effective date 
through the date of the sale, resulting in a gain of $28.6 million.  During 2011, the Company completed the sale of Pioneer Tunisia 

58

PIONEER NATURAL RESOURCES COMPANY

to an unaffiliated party for cash proceeds of $802.5 million, excluding cash and cash equivalents sold, resulting in a gain of $645.2 
million.  

See Note C of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary 

Data" for more information regarding the Company's divestitures.

Financing activities. Net cash provided by financing activities during 2013 was $157.8 million, as compared to net cash 
provided by financing activities during 2012 and 2011 of $1.1 billion and $457.4 million, respectively. During 2013, the significant 
components of financing activities included $1.1 billion of net payments on long-term debt, the Company's completion of an 
offering of 10.35 million shares of its common stock in February 2013 at a per-share price, after underwriting and offering expenses, 
of  $123.76  for  a  total  of  $1.3  billion  of  realized  net  proceeds  and  $47.2  million  of  dividend  payments  and  distributions  to 
noncontrolling interests. During 2012, the significant components of financing activities included $1.2 billion of net borrowings 
on long-term debt and $45.9 million of dividend payments and distributions to noncontrolling interests.  During 2011, significant 
components of financing activities included $484.2 million of net proceeds received from the offering of 5.5 million shares of the 
Company's common stock and $123.0 million of net proceeds received from the sale of 4.4 million common units representing 
limited partner interests in Pioneer Southwest, partially offset by $98.3 million of net principal payments on long-term debt and 
$36.3 million of dividend payments and distributions to noncontrolling interests. 

The following provides a description of the Company's significant financing activities during 2013, 2012 and 2011:

•  During December 2012 and March 2013, respectively, the Company's stock price met the price threshold that caused 
the Convertible Senior Notes to be convertible during the six months ended June 30, 2013 at the option of the holders 
into a combination of cash and the Company's common stock based on a formula set forth in the indenture supplement 
pursuant to which the Convertible Senior Notes were issued.  On April 15, 2013, the Company announced that it would 
exercise its option to redeem all Convertible Senior Notes that had not been converted by the holders before May 16, 
2013. Holders of $479.1 million principal amount of the Convertible Senior Notes exercised their right to convert their 
Convertible Senior Notes into cash and shares of the Company's common stock.  The Company paid the tendering 
holders $479.1 million of cash and issued to the tendering holders 4.4 million shares of the Company's common stock 
in accordance with the terms of the Convertible Senior Notes indenture agreement.  On May 16, 2013, the Company 
paid $845 thousand in principal and interest to redeem all Convertible Senior Notes that remained outstanding.

•  During February 2013, the Company completed the sale of 10.35 million shares of its common stock for $1.3 billion 

of net cash proceeds.

•  During December 2012, the Company amended its credit facility with a syndicate of financial institutions to increase 

the aggregate loan commitments to $1.5 billion from $1.25 billion and extend its maturity to December 2017; 

•  During June 2012, the Company issued $600 million of 3.95% Senior Notes due 2022 and received proceeds, net of 

$8.5 million of offering discounts and costs, of $591.5 million;

•  During December 2011, Pioneer Southwest completed the public offering of 4.4 million common units of Pioneer 
Southwest,  representing  limited  partnership  interests,  at  a  per-unit  price  of  $29.20,  before  offering  costs.  Of  the 
4.4 million common units, Pioneer sold 1.8 million of its Pioneer Southwest common unit holdings for net proceeds 
of  $50.5  million  and  Pioneer  Southwest  issued  2.6 million  new  common  units  for  net  proceeds  of  $72.5  million, 
including offering costs. Pioneer Southwest used its net proceeds to reduce its credit facility borrowings; and

•  During November 2011, the Company completed the sale of 5.5 million shares of its common stock for $484.2 million 

of net proceeds. 

  See Note G of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary 

Data" for additional information regarding the significant financing activities.

As  the  Company  pursues  its  strategy,  it  may  utilize  various  financing  sources,  including  fixed  and  floating  rate  debt, 
convertible securities, preferred stock or common stock. The Company cannot predict the timing or ultimate outcome of any such 
actions as they are subject to market conditions, among other factors. The Company may also issue securities in exchange for oil 
and gas properties, stock or other interests in other oil and gas companies or related assets. Additional securities may be of a class 
preferred to common stock with respect to such matters as dividends and liquidation rights and may also have other rights and 
preferences as determined by the Board.

Liquidity. The Company's principal sources of short-term liquidity are cash and cash equivalents and unused borrowing 
capacity under the Company's credit facility. As of December 31, 2013, the Company had no outstanding borrowings under the 
credit facility, leaving $1.5 billion of unused borrowing capacity.  The Company was in compliance with all of its debt covenants.  
The Company's credit facility contains certain financial covenants, which include the maintenance of a ratio of total debt to book 
capitalization, subject to certain adjustments, not to exceed .60 to 1.0, which is above the Company's December 31, 2013 ratio 
of .24 to 1.0. If internal cash flows and cash on hand do not meet the Company's expectations, the Company may reduce its level 
59

PIONEER NATURAL RESOURCES COMPANY

of capital expenditures, reduce dividend payments, and/or fund a portion of its capital expenditures using borrowings under the 
Company's credit facility, issuances of debt or equity securities or other sources, such as sales of joint interests or nonstrategic 
assets. The Company cannot provide any assurance that needed short-term or long-term liquidity will be available on acceptable 
terms or at all. Although the Company expects that the combination of internal operating cash flows, cash and cash equivalents 
on hand, proceeds from the divestiture of assets held for sale, proceeds from the sales of other nonstrategic assets and, if necessary, 
available capacity under the Company's credit facility will be adequate to fund 2014 capital expenditures and dividend payments 
and provide adequate liquidity to fund other needs, no assurances can be given that such funding sources will be adequate to meet 
the Company's future needs.

Debt ratings. The Company is rated as investment grade by three credit rating agencies. The Company receives debt credit 
ratings from several of the major ratings agencies, which are subject to regular reviews. The Company believes that each of the 
rating agencies considers many factors in determining the Company's ratings, including: production growth opportunities, liquidity, 
debt levels, asset composition and proved reserve mix. A reduction in the Company's debt ratings could increase the interest rates 
that the Company incurs on credit facility borrowings and could negatively affect the Company's ability to obtain additional 
financing or the interest rate, fees and other terms associated with such additional financing. 

Book capitalization and current ratio. The Company's net book capitalization at December 31, 2013 was $8.9 billion, 
consisting  of  $392.6  million  of  cash  and  cash  equivalents,  debt  of  $2.7  billion  and  stockholders'  equity  of  $6.6  billion. The 
Company's debt to book capitalization decreased to 25 percent at December 31, 2013 from 37 percent at December 31, 2012, 
primarily due to an increase in cash and cash equivalents of $163.3 million and a decrease in long-term debt of $1.1 billion, partially 
offset by a net loss of $799.5 million during 2013. The Company's ratio of current assets to current liabilities increased to 1.38 to 
1.00 at December 31, 2013, as compared to 1.02 to 1.00 at December 31, 2012, primarily due to the reclassification of long-term 
assets to assets held for sale.  

Critical Accounting Estimates

The Company prepares its consolidated financial statements for inclusion in this Report in accordance with GAAP. See 
Note B of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for a 
comprehensive discussion of the Company's significant accounting policies. GAAP represents a comprehensive set of accounting 
and disclosure rules and requirements, the application of which requires management judgments and estimates including, in certain 
circumstances,  choices  between  acceptable  GAAP  alternatives. The  following  is  a  discussion  of  the  Company's  most  critical 
accounting estimates, judgments and uncertainties that are inherent in the Company's application of GAAP.

Asset retirement obligations. The Company has significant obligations to remove tangible equipment and facilities and to 
restore the land at the end of oil and gas production operations. The Company's removal and restoration obligations are primarily 
associated  with  plugging  and  abandoning  wells.  Estimating  the  future  restoration  and  removal  costs  is  difficult  and  requires 
management to make estimates and judgments because most of the removal obligations are many years in the future and contracts 
and regulations often have vague descriptions of what constitutes removal. Asset removal technologies and costs are constantly 
changing, as are regulatory, political, environmental, safety and public relations considerations.

Inherent in the present value calculation are numerous assumptions and judgments including the ultimate settlement amounts, 
credit adjusted discount rates, timing of settlement and changes in the legal, regulatory, environmental and political environments. 
To  the  extent  future  revisions  to  these  assumptions  impact  the  present  value  of  the  existing  asset  retirement  obligations,  a 
corresponding adjustment is generally made to the oil and gas property balance. See Notes B and I of Notes to Consolidated 
Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information regarding the 
Company's asset retirement obligations.

Successful efforts method of accounting. The Company utilizes the successful efforts method of accounting for oil and 
gas producing activities as opposed to the alternate acceptable full cost method. In general, the Company believes that net assets 
and net income are more conservatively measured under the successful efforts method of accounting for oil and gas producing 
activities than under the full cost method, particularly during periods of active exploration. The critical difference between the 
successful efforts method of accounting and the full cost method is as follows: under the successful efforts method, exploratory 
dry holes and geological and geophysical exploration costs are charged against earnings during the periods in which they occur; 
whereas, under the full cost method of accounting, such costs and expenses are capitalized as assets, pooled with the costs of 
successful wells and charged against the earnings of future periods as a component of depletion expense. During 2013, 2012 and 
2011, the Company recognized exploration, abandonment, geological and geophysical expense from continuing operations of 
$98.4 million, $98.3 million and $80.7 million, respectively. During 2013, 2012 and 2011, the Company recognized exploration, 
abandonment, geological and geophysical expense from discontinued operations of $52.7 million, $108.1 million and $44.9 million, 
respectively, under the successful efforts method.

Proved reserve estimates. Estimates of the Company's proved reserves included in this Report are prepared in accordance 

with GAAP and SEC guidelines. The accuracy of a reserve estimate is a function of:

• 
• 
• 
• 

the quality and quantity of available data;
the interpretation of that data;
the accuracy of various mandated economic assumptions; and
the judgment of the persons preparing the estimate.

The Company's proved reserve information included in this Report as of December 31, 2013, 2012 and 2011 was prepared 
by the Company's engineers and audited by independent petroleum engineers with respect to the Company's major properties. 
Estimates prepared by third parties may be higher or lower than those included herein.

Because these estimates depend on many assumptions, all of which may substantially differ from future actual results, 
proved reserve estimates will be different from the quantities of oil and gas that are ultimately recovered. In addition, results of 
drilling, testing and production after the date of an estimate may justify, positively or negatively, material revisions to the estimate 
of proved reserves.

It should not be assumed that the Standardized Measure included in this Report as of December 31, 2013 is the current 
market value of the Company's estimated proved reserves. In accordance with SEC requirements, the Company based the 2013 
Standardized Measure on a twelve month average of commodity prices on the first day of the month 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,"  "Item  2.  Properties"  and  Supplementary  Information  included  in  "Item  8.  Financial 
Statements and Supplementary Data" for additional information regarding estimates of proved reserves.

The Company's estimates of proved reserves materially impact depletion expense. If the estimates of proved reserves decline, 
the rate at which the Company records depletion expense will increase, reducing future net income. 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 the Company's assessment of its proved properties and goodwill for 
impairment.

Impairment of proved oil and gas properties. The Company reviews its proved properties to be held and used whenever 
management  determines  that  events  or  circumstances  indicate  that  the  recorded  carrying  value  of  the  properties  may  not  be 
recoverable. Management assesses whether or not an impairment provision is necessary based upon estimated future recoverable 
proved and risk-adjusted probable and possible reserves, Management's Price Outlooks, production and capital costs expected to 
be incurred to recover the reserves; discount rates commensurate with the nature of the properties and net cash flows that may be 
generated by the properties. Proved oil and gas properties are reviewed for impairment at the level at which depletion of proved 
properties is calculated. See Notes B and D of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements 
and Supplementary Data" for information regarding the Company's impairment assessments.

Impairment of unproved oil and gas properties. At December 31, 2013, the Company carried unproved property costs of 
$123.4 million. Management assesses unproved oil and gas properties for impairment on a project-by-project basis. Management's 
impairment assessments include evaluating the results of exploration activities, Management's Price Outlooks and planned future 
sales or expiration of all or a portion of such projects.

Suspended  wells.  The  Company  suspends  the  costs  of  exploratory  wells  that  discover  hydrocarbons  pending  a  final 
determination of the commercial potential of the discovery. The ultimate disposition of these well costs is dependent on the results 
of future drilling activity and development decisions. If the Company decides not to pursue additional appraisal activities or 
development of these fields, the costs of these wells will be charged to exploration and abandonment expense.

The Company 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.
(ii)  The Company is making sufficient progress assessing the reserves and the economic and operating viability of the 

project.

Due to the capital intensive nature and the geographical location of certain projects, it may take an extended period of time 
to evaluate the future potential of an exploration project 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 

61

PIONEER NATURAL RESOURCES COMPANY

approval to drill additional appraisal wells. These activities are ongoing and being pursued constantly. Consequently, the Company's 
assessment of suspended exploratory well costs is continuous until a decision can be made that the well has found proved reserves 
to sanction the project or is noncommercial and is impaired. See Note F of Notes to Consolidated Financial Statements included 
in  "Item  8.  Financial  Statements  and  Supplementary  Data"  for  additional  information  regarding  the  Company's  suspended 
exploratory well costs.

Deferred  tax  asset  valuation  allowances.  The  Company  continually  assesses  both  positive  and  negative  evidence  to 
determine whether it is more likely than not that its deferred tax assets, if any, will be realized prior to their expiration. Pioneer 
monitors Company-specific, oil and gas industry and worldwide economic factors and reassesses the likelihood that the Company's 
net operating loss carryforwards and other deferred tax attributes in each jurisdiction will be utilized prior to their expiration. 
There can be no assurance that facts and circumstances will not materially change and require the Company to establish deferred 
tax asset valuation allowances in certain jurisdictions in a future period.

Goodwill impairment. The Company reviews its goodwill for impairment at least annually.  During the third and fourth 
quarters of 2013, the Company performed qualitative assessments of goodwill to assess whether it is more likely than not that the 
fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-
step goodwill impairment test.  The Company determined that it was not likely that the Company's goodwill was impaired. 

For assessments prior to 2012, the Company was required to estimate the fair value of the assets and liabilities of the 
reporting units that have goodwill.  There is considerable judgment involved in estimating fair values, particularly in determining 
the valuation methodologies to utilize, the estimation of proved reserves as described above and the weighting of different valuation 
methodologies applied. See Note B of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and 
Supplementary Data" for additional information regarding goodwill and assessments of goodwill for impairment.

Litigation and environmental contingencies. The Company makes 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 the Company determines the loss to be both probable and reasonably estimable. See 
Note J of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for 
additional information regarding the Company's commitments and contingencies.

Valuation of stock-based compensation. The Company calculates 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. The 
Company utilizes (a) the Black-Scholes option pricing model to measure the fair value of stock options, (b) the closing stock price 
on the day prior to the date of grant for the fair value of restricted stock awards, (c) the closing stock price at the balance sheet 
date for restricted stock awards that are expected to be settled wholly or partially in cash on their vesting date, (d) the Monte Carlo 
simulation method for the fair value of performance unit awards and (e) a probability forecasted fair value method for Series B 
unit awards issued by Sendero. See Note H of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements 
and Supplementary Data" for information regarding the Company's stock-based compensation.

Valuation of other assets and liabilities at fair value. The Company periodically measures and records certain assets and 
liabilities at fair value. The assets and liabilities that the Company periodically measures and records at fair value include trading 
securities, commodity derivative contracts and interest rate contracts. The Company also measures and discloses certain financial 
assets and liabilities at fair value, such as long-term debt. The valuation methods used by the Company to measure the fair values 
of these assets and liabilities require considerable management judgment and estimates to derive the inputs necessary to determine 
fair value estimates, such as future prices, credit-adjusted risk-free rates and current volatility factors. See Note D of Notes to 
Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for information regarding 
the methods used by management to estimate the fair values of these assets and liabilities.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The following quantitative and qualitative information is provided about financial instruments to which the Company was 
a party as of December 31, 2013, and from which the Company may incur future gains or losses from changes in commodity 
prices or interest rates.

The fair values of the Company's long-term debt and derivative contracts are determined based on observable inputs and 
utilizing the Company's valuation models and applications. As of December 31, 2013, the Company was a party to commodity 
swap contracts, interest rate swap contracts, commodity collar contracts and commodity collar contracts with short put options. 
See Notes D and E of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary 
Data" for additional information regarding the Company's fair value measurements and derivative contracts. The following table

Commodity derivative instruments and price sensitivity. The following table provides information about the Company's oil, 
NGL and gas derivative financial instruments that were sensitive to changes in commodity prices as of December 31, 2013. Although 
the cash flow effects are mitigated by the Company's derivative instruments, declines in oil, NGL and gas prices reduce the Company's 
sales revenues.

The Company manages commodity price risk with derivative contracts, such as swaps, collar contracts and collar contracts 
with short put options. Swap contracts provide a fixed price for a notional amount of sales volumes. Collar contracts provide minimum 
("floor" or "long put") and maximum ("ceiling" or "short call") prices on a notional amount of sales volumes, thereby allowing some 
price participation if the relevant index price closes above the floor price. Collar contracts with short put options differ from other 
collar contracts by virtue of the short put option price, below which the Company's realized price will exceed the variable market 
prices by the floor-to-short put price differential.

See  Notes  B,  D  and  E  of  Notes  to  Consolidated  Financial  Statements  included  in  "Item  8.  Financial  Statements  and 
Supplementary Data" for a description of the accounting procedures followed by the Company relative to its derivative financial 
instruments and for specific information regarding the terms of the Company's derivative financial instruments that are sensitive to 
changes in oil, NGL or gas prices.

In  accordance  with  Financial Accounting  Standards  Board Accounting  Standards  Codification  ("ASC")  210-20  and ASC 
815-10,  the  Company  classifies  the  fair  value  amounts  of  derivative  assets  and  liabilities  executed  under  master  netting 
arrangements as net derivative assets or net derivative liabilities, as the case may be. The net asset and liability amounts shown 
above have been provided on a commodity contract-type basis, which may differ from their master netting arrangements 
classifications.
Subsequent to December 31, 2013, the Company entered into rollfactor swap contracts for 5,000 BBLs per day of the Company's 
March through December 2014 production with a NYMEX roll price of $0.82 per BBL and 5,000 BBLs per day of the 
Company's 2015 production with a NYMEX roll price of $0.60 per BBL. Rollfactor swap contracts fix the difference between 
(i) each day's price per BBL of WTI for the first nearby month less (ii) the price per BBL of WTI for the second nearby 
NYMEX month, multiplied by .6667; plus (iii) each day's price per BBL of WTI for the first nearby month less (iv) the price 
per BBL of WTI for the third nearby NYMEX month, multiplied by .3333.
The average forward NYMEX oil prices are based on February 20, 2014 market quotes.

price and the NYMEX price.
The average forward basis differential prices are based on February 20, 2014 market quotes for basis differentials between 
the relevant index prices and NYMEX-quoted forward prices.

Marketing and basis transfer derivatives. The Company enters into buy and sell marketing arrangements to fulfill firm pipeline 
transportation commitments. Associated with these marketing arrangements, the Company may enter into index swaps to mitigate 
price risk. As of December 31, 2013, the Company had no open marketing derivative positions. Subsequent to December 31, 2013, 
the Company entered into marketing gas index swap contracts for 20,000 MMBTU per day of March 2014 volumes with a price 
differential of $0.34 per MMBTU, 10,000 MMBTU per day of April through October 2014 volumes with a price differential of $0.36 
per MMBTU and 30,000 MMBTU per day of April through December 2014 volumes with a price differential of $0.30 per MMBTU.

Qualitative Disclosures

The Company's primary market risk exposures are to changes in commodity prices and interest rates. These risks did not 

change materially from December 31, 2012 to December 31, 2013.

Non-derivative financial instruments. The Company is a borrower under fixed rate debt instruments and, from time to 
time, under a variable rate debt instrument that gives rise to interest rate risk. The Company's objective in borrowing under fixed 
or variable rate debt is to satisfy capital requirements while minimizing the Company's costs of capital. The Company also enters 
into oil and gas purchase and sale transactions with third parties to satisfy unused pipeline capacity commitments and to diversify 
a portion of the Company's WTI oil sales to a Gulf Coast oil price. See Note G of Notes to Consolidated Financial Statements 
included in "Item 8. Financial Statements and Supplementary Data" for a discussion of the Company's debt instruments.

Derivative financial instruments. The Company, from time to time, utilizes commodity price and interest rate derivative 
contracts to mitigate commodity price and interest rate risks in accordance with policies and guidelines approved by the Board. 
In accordance with those policies and guidelines, the Company's executive management determines the appropriate timing and 
extent of derivative transactions.

REPORT OF INDEPENDENT REGISTERED PUBLIC
ACCOUNTING FIRM

The Board of Directors and Stockholders of
Pioneer Natural Resources Company

We have audited the accompanying consolidated balance sheets of Pioneer Natural Resources Company (the "Company") 
as of December 31, 2013 and 2012, and the related consolidated statements of operations, comprehensive income (loss), equity 
and cash flows for each of the three years in the period ended December 31, 2013. These financial statements are the responsibility 
of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United 
States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial 
statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and 
disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates 
made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a 
reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial 
position of Pioneer Natural Resources Company at December 31, 2013 and 2012, and the consolidated results of its operations 
and its cash flows for each of the three years in the period ended December 31, 2013, in conformity with U.S. generally accepted 
accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), 
Pioneer  Natural  Resources  Company's  internal  control  over  financial  reporting  as  of  December  31,  2013,  based  on  criteria 
established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway 
Commission (1992 framework) and our report dated February 26, 2014 expressed an unqualified opinion thereon.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
December 31, 2013, 2012 and 2011

NOTE A.    Organization and Nature of Operations

Pioneer Natural Resources Company ("Pioneer" or "the Company") is a Delaware corporation whose common stock is 
listed and traded on the New York Stock Exchange. The Company is a large independent oil and gas exploration and production 
company in the United States, with continuing field operations in the Permian Basin in West Texas, the Eagle Ford Shale play in 
South Texas, the Raton field in southeastern Colorado, the Hugoton field in southwest Kansas and the West Panhandle field in the 
Texas Panhandle.  The Company's objective is to maximize shareholder investment returns by maintaining financial flexibility, 
capital allocation discipline and enhancing net asset value through accretive drilling programs, joint ventures and acquisitions. 

NOTE B.    Summary of Significant Accounting Policies

Principles of consolidation. The consolidated financial statements include the accounts of the Company and its wholly-
owned and majority-owned subsidiaries since their acquisition or formation. In accordance with generally accepted accounting 
principles in the United States ("GAAP"), the Company proportionately consolidates certain affiliate partnerships that are less 
than wholly-owned and are involved in oil and gas producing activities. All material intercompany balances and transactions have 
been eliminated.

Certain reclassifications have been made to the 2012 and 2011 financial statement and footnote amounts in order to conform 

them to the 2013 presentations. 

In addition, the presentation of purchases and sales of third-party oil and gas has been revised in 2012 and 2011 to present 
separately the gross sales of purchased oil and gas and costs of purchased oil and gas. Previously, the sales and purchases were 
netted in other expense. Revenues and costs from the purchase and sale transactions are presented on a gross basis as the Company 
acts as a principal in the transactions by assuming the risks and rewards of ownership, including credit risk, of the oil and gas 
purchased and assumes responsibility to deliver the oil and gas volumes sold.  This revision did not impact the Company's balance 
sheet, net income (loss) from continuing operations, equity or cash flows.  While not material to the 2012 and 2011 financial 
statements as a whole, the presentation has been revised to enhance consistency.  The following individual line items were affected 
in addition to total revenues and other income, and total costs and expenses:

Use  of  estimates  in  the  preparation  of  financial  statements.  Preparation  of  the  accompanying  consolidated  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. Depletion of oil and gas properties and impairment of goodwill 
and proved and unproved oil and gas properties, in part, is determined using estimates of proved, probable and possible oil and 
gas reserves. There are numerous uncertainties inherent in the estimation of quantities of proved, probable and possible 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 gas properties are subject to numerous uncertainties including, among others, estimates of future 
recoverable reserves and commodity price outlooks. Actual results could differ from the estimates and assumptions utilized.

December 31, 2013, 2012, and 2011

Cash and cash equivalents. The Company's cash and cash equivalents include depository accounts held by banks and 

marketable securities with original issuance maturities of 90 days or less.

Accounts receivable. As of December 31, 2013 and 2012, the Company had accounts receivable – trade, net of allowances 
for bad debts, of $430.7 million and $316.9 million, respectively. The Company's accounts receivable – trade are primarily comprised 
of oil and gas sales receivables, joint interest receivables and other receivables for which the Company does not require collateral 
security.

As of December 31, 2013 and 2012, the Company's allowances for doubtful accounts totaled $1.4 million and $1.5 million, 
respectively. The Company establishes allowances for bad debts equal to the estimable portions of accounts receivable for which 
failure to collect is considered probable. The Company estimates the portions of joint interest receivables for which failure to 
collect is probable based on percentages of joint interest receivables that are past due. The Company estimates the portions of 
other receivables for which failure to collect is probable based on the relevant facts and circumstances surrounding the receivable. 
Allowances for doubtful accounts are recorded as reductions to the carrying values of the receivables included in the Company's 
consolidated balance sheets and as charges to other expense in the consolidated statements of operations in the accounting periods 
during which failure to collect an estimable portion is determined to be probable. 

  Inventories.  The Company's inventories consist of materials, supplies and commodities.  The Company's materials and 
supplies inventory is primarily comprised of oil and gas drilling or repair items such as tubing, casing, proppant used to fracture-
stimulate oil and gas wells, chemicals, operating supplies and ordinary maintenance materials and parts. The materials and supplies 
inventory is primarily acquired for use in future drilling operations or repair operations and is carried at the lower of cost or market, 
on a first-in, first-out cost basis. Valuation reserve allowances for materials and supplies inventories are recorded as reductions to 
the carrying values of the materials and supply inventories in the Company's consolidated balance sheets and as charges to other 
expense in the accompanying consolidated statements of operations.  

Commodities inventories are carried at the lower of average cost or market, on a first-in, first-out basis. The Company's 
commodities inventories consist of oil held in storage and natural gas liquids ("NGLs") and gas pipeline fill volumes. Any valuation 
allowances of commodities inventories are recorded as reductions to the carrying values of the commodities inventories included 
in the Company's consolidated balance sheets and as charges to other expense in the consolidated statements of operations.

The following table presents the Company's materials and supplies and commodities inventories as of December 31, 

2013 and 2012:

____________________
(a)  As  of  December  31,  2013  and  2012,  the  Company's  materials  and  supplies  inventories  were  net  of  valuation  reserve 
allowances of $31.8 million and $4.6 million, respectively.  See Note D for additional information regarding inventory 
impairments.
Included in other noncurrent assets in the Company's accompanying consolidated balance sheet.

(b) 

Oil and gas properties. The Company utilizes the successful efforts method of accounting for its oil and gas properties. 
Under  this  method,  all  costs  associated  with  productive  wells  and  nonproductive  development  wells  are  capitalized  while 
nonproductive exploration costs and geological and geophysical expenditures are expensed. The Company capitalizes interest on 
expenditures for significant development projects, generally when the underlying project is sanctioned, until such projects are 
ready for their intended use. For large development projects requiring significant upfront development costs to support the drilling 
and production of a planned group of wells, the Company continues to capitalize interest on the portion of the development costs 
attributable to the planned wells yet to be drilled.

The Company 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:

77

PIONEER NATURAL RESOURCES COMPANY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
December 31, 2013, 2012, and 2011

(i)  The well has found a sufficient quantity of reserves to justify its completion as a producing well.
(ii)  The Company is making sufficient progress assessing the reserves and the economic and operating viability of the 

project.

Due to the capital intensive nature and the geographical location of certain projects, it may take an extended period of time 
to evaluate the future potential of an exploration project and the 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 data in the area, transportation or processing facilities and/or 
getting  partner  approval  to  drill  additional  appraisal  wells.  These  activities  are  ongoing  and  are  being  pursued  constantly. 
Consequently, the Company's assessment of suspended exploratory well costs is continuous until a decision can be made that the 
project  has  found  sufficient  proved  reserves  to  sanction  the  project  or  is  noncommercial  and  is  charged  to  exploration  and 
abandonments expense. See Note F for additional information regarding the Company's suspended exploratory well costs.

The Company owns interests in six gas processing plants and nine treating facilities. The Company is the operator of two 
of the gas processing plants and all nine of the treating facilities. The Company's ownership interests in the gas processing plants 
and treating facilities are primarily to accommodate handling the Company's gas production and thus are considered a component 
of the capital and operating costs of the respective fields that they service. To the extent that there is excess capacity at a plant or 
treating facility, the Company attempts to process third party gas volumes for a fee to keep the plant or treating facility at capacity. 
All revenues and expenses derived from third party gas volumes processed through the plants and treating facilities are reported 
as components of oil and gas production costs. Third party revenues generated from the processing plants and treating facilities 
in continuing operations for the three years ended December 31, 2013, 2012 and 2011 were $57.2 million, $34.4 million and $42.6 
million, respectively. Third party expenses attributable to the processing plants and treating facilities in continuing operations for 
the same respective periods were $30.1 million, $26.5 million and $22.6 million. The capitalized costs of the plants and treating 
facilities are included in proved oil and gas properties and are depleted using the unit-of-production method along with the other 
capitalized costs of the field that they service.

The capitalized costs of proved properties are depleted using the unit-of-production method based on proved reserves. Costs 
of significant nonproducing properties, wells in the process of being drilled and development projects are excluded from depletion 
until the related project is completed and proved reserves are established or, if unsuccessful, impairment is determined.

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, depreciation and amortization, if doing so does not materially impact 
the depletion rate of an amortization base. Generally, no gain or loss is recognized until an entire amortization base is sold. However, 
gain or loss is recognized from the sale of less than an entire amortization base if the disposition is significant enough to materially 
impact the depletion rate of the remaining properties in the amortization base.

The Company performs assessments of its long-lived assets to be held and used, including proved oil and gas properties 
accounted for under the successful efforts method of accounting, 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 these circumstances, the Company recognizes an impairment loss for the amount by which 
the carrying amount of the assets exceeds the estimated fair value of the assets. See Note D for additional information regarding 
the Company's impairment of proved oil and gas properties.

Unproved oil and gas properties are periodically assessed for impairment on a project-by-project basis. These impairment 
assessments are affected by the results of exploration activities, commodity price outlooks, planned future sales or expirations of 
all or a portion of such projects. If the estimated future net cash flows attributable to such projects are not expected to be sufficient 
to fully recover the costs invested in each project, the Company will recognize an impairment loss at that time. 

Goodwill. During 2004, the Company recorded goodwill associated with a business combination, which represents the cost 
of an acquired entity over the net amounts assigned to assets acquired and liabilities assumed.  In accordance with GAAP, goodwill 
is not amortized to earnings, but is assessed for impairment whenever events or circumstances indicate that impairment of the 
carrying value of goodwill is likely, but no less often than annually. If the carrying value of goodwill is determined to be impaired, 
it is reduced for the impaired value with a corresponding charge to earnings in the period in which it is determined to be impaired. 
During the third quarter of 2013, the Company performed a qualitative assessment of goodwill to determine whether it was more 
likely than not that the fair value of the Company's reporting unit was less than its carrying amount as a basis for determining 

78

PIONEER NATURAL RESOURCES COMPANY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
December 31, 2013, 2012, and 2011

whether it was necessary to perform the two-step goodwill impairment test.   Based upon the results of the assessment, the Company 
determined that it was not likely that the Company's goodwill was impaired. 

For the year ended December 31, 2013, the Company reduced the carrying value of goodwill by $23.8 million, reflecting 
the portion of the Company's goodwill related to assets sold or included in assets held for sale at December 31, 2013, primarily 
associated with the sale of 40 percent of Pioneer's interest in 207,000 net acres leased by the Company in the horizontal Wolfcamp 
Shale play in the southern portion of the Spraberry field in West Texas, and the planned sales of the Company's Alaska subsidiary 
and Barnett Shale net assets.  See Note C for additional information regarding the Company's divestitures.  At December 31, 2013, 
the Company performed a qualitative assessment of its remaining goodwill to determine whether it is more likely than not that the 
fair value of the Company's reporting unit is less than its carrying amount, and the Company determined that it is not likely that 
the Company's remaining goodwill is impaired.

Other property and equipment, net. Other property and equipment is recorded at cost. At December 31, 2013 and 2012, 

respectively, the net carrying value of other property and equipment consisted of the following:

and $395.9 million, respectively.
Includes  sand  mines,  sales  facilities  and  unproved  leaseholds  that  primarily  provide  the  Company  and  other  unrelated 
customers with proppant used in the fracture stimulation of oil and gas wells.
Includes drilling rigs, well servicing rigs and equipment and fracture stimulation equipment including assets owned by 
subsidiaries that provide drilling, pumping and well services on Company-operated properties.  As of December 31, 2013, 
the Company owned 15 drilling rigs, eleven fracture stimulation fleets and other oilfield services equipment, including 
pulling units, fracture stimulation tanks, water transport trucks, hot oilers, blowout preventers, construction equipment and 
fishing tools. During December 2013, the Company committed to a plan to sell its majority interest in Sendero Drilling 
Company, LLC ("Sendero"), which owns the Company's 15 vertical drilling rigs, to Sendero's minority interest owner.  
Associated therewith, the Company has classified the assets and liabilities of Sendero, including $17.9 million of drilling 
rigs, as assets held for sale in the accompanying consolidated balance sheet as of December 31, 2013.  See Note C for 
additional information.

  The primary purposes of the Company's sand mines and drilling, pumping and well services operations are to accommodate 
the Company's drilling and producing operations by increasing the availability of supplies, equipment and services, rather than 
being dependent on third-party availability, and to contain associated costs.  All intercompany gains or losses of the Company's 
sand mines and drilling, pumping and well services operations are eliminated.   

Earnings from sales of proppant and from providing drilling, pumping and well services to third-party customers and working 
interest  owners  in  Company-operated  properties  are  included  in  interest  and  other  income  in  the  accompanying  consolidated 
statements of operations.

The capitalized costs of proved sand properties are depleted using the unit-of-production method based on proved sand 
reserves.  Equipment items are generally depreciated by individual component on a straight line basis over their economic useful 
lives, which are generally from two to 12 years. Leasehold improvements are amortized over the lesser of their economic useful 
lives or the underlying terms of the associated leases.

December 31, 2013, 2012, and 2011

The Company evaluates other property and equipment for potential impairment whenever indicators of impairment are 
present. Circumstances that could indicate potential impairment include: significant adverse changes in industry trends and the 
economic outlook; legal actions; regulatory changes; and significant declines in utilization rates or oil and gas prices. If it is 
determined  that  other  property  and  equipment  is  potentially  impaired,  the  Company  performs  an  impairment  evaluation  by 
estimating the future undiscounted net cash flow from the use and eventual disposition of other property and equipment grouped 
at the lowest level that cash flows can be identified. If the sum of the future undiscounted net cash flows is less than the net book 
value of the property, an impairment loss is recognized for the excess, if any, of the assets' net book value over its estimated fair 
value.

Investment in unconsolidated affiliate. During 2010, the Company formed EFS Midstream LLC ("EFS Midstream") to 
own and operate gas and liquids gathering, treating and transportation assets in the Eagle Ford Shale play in South Texas. During 
June 2010, the Company sold a 49.9 percent member interest in EFS Midstream to an unaffiliated third party for $46.4 million of 
cash proceeds. Associated therewith, the Company recorded a $46.2 million deferred gain that is being amortized as a reduction 
in production costs over a 20 year period, representing the term of a continuing commitment of Pioneer to deliver production 
volumes through EFS Midstream handling and gathering facilities. The deferred gain is included in other current and noncurrent 
liabilities in the Company's accompanying consolidated balance sheet.

The Company does not have control of EFS Midstream. Consequently, the Company accounts for this investment under 
the equity method of accounting for investments in unconsolidated affiliates. Under the equity method, the Company's investment 
in unconsolidated affiliates is increased for investments made and the investor's share of the investee's net income, and decreased 
for distributions received, the carrying value of member interests sold and the investor's share of the investee's net losses. 

The Company's equity interest in the net income or loss of EFS Midstream is recorded in interest and other income, net of 
eliminations of the profit associated with gathering, treating and transportation fees charged to the Company by EFS Midstream, 
in the accompanying consolidated statements of operations.  See Note M for the Company's equity interest in the net income of 
EFS Midstream for the years ended December 31, 2013, 2012 and 2011.

Asset retirement obligations. The Company records a liability for the fair value of an asset retirement obligation in the 
period in which it is incurred if a reasonable estimate of fair value can be made. Asset retirement obligations are generally capitalized 
as part of the carrying value of the long-lived asset to which it relates. Conditional asset retirement obligations meet the definition 
of liabilities and are recognized when incurred if their fair values can be reasonably estimated.

The Company records the current and noncurrent portions of asset retirement obligations in other current liabilities and 
other liabilities, respectively, in the accompanying consolidated balance sheets and expenditures are classified as cash used in 
operating activities in the accompanying consolidated statements of cash flows.  See Note I for additional information about the 
Company's asset retirement obligations.

Treasury stock. Treasury stock purchases are recorded at cost. Upon reissuance, the cost of treasury shares held is reduced 

by the average purchase price per share of the aggregate treasury shares held.

Issuance of common stock. In February 2013, the Company issued 10.35 million shares of its common stock and realized 

$1.3 billion of cash proceeds, net of associated underwriting and offering expenses. 

Noncontrolling interest in consolidated subsidiaries. The Company owns the majority interests in certain subsidiaries with 
operations in the United States. Prior to December 17, 2013, the Company owned a 0.1 percent general partner interest and a 52.4 
percent limited partner interest in Pioneer Southwest Energy Partners L.P. ("Pioneer Southwest") and consolidated the financial 
position, results of operations and cash flows of Pioneer Southwest with those of Pioneer.  Pioneer Southwest owned proved and 
unproved oil and gas properties in the Spraberry field in the Permian Basin of West Texas. On December 17, 2013, the holders of 
a majority of the outstanding common units of Pioneer Southwest approved an amended agreement and plan of merger, pursuant 
to which (i) all of the then outstanding common units of Pioneer Southwest were canceled and converted into the right to receive 
0.2325 of a share of common stock of the Company and (ii) Pioneer Southwest became a wholly-owned subsidiary of the Company.  
The changes in the Company's ownership of Pioneer Southwest were accounted for by eliminating the noncontrolling interest 
attributable to Pioneer Southwest. See Note C for additional information about Pioneer Southwest and the amended agreement 
and plan of merger.

Noncontrolling interests in the net assets of consolidated subsidiaries totaled $13.2 million and $178.0 million as of December 
31, 2013 and 2012, respectively. The Company recorded net income attributable to the noncontrolling interests of $38.9 million, 
$50.5 million and $47.4 million for the years ended December 31, 2013, 2012 and 2011, respectively.

Revenue recognition. The Company recognizes revenue when it is realized or realizable and earned. Revenues are considered 
realized or realizable and earned when: (i) persuasive evidence of an arrangement exists, (ii) delivery has occurred or services 
have been rendered, (iii) the seller's price to the buyer is fixed or determinable and (iv) collectability is reasonably assured.

The Company uses the entitlements method of accounting for oil, NGLs and gas revenues. Sales proceeds in excess of the 
Company's entitlement are included in other liabilities and the Company's share of sales taken by others is included in other assets 
in the accompanying consolidated balance sheets.

The Company had no material oil or NGL entitlement assets or liabilities as of December 31, 2013 or 2012. The following 
table presents the Company's gas entitlement assets and liabilities with their associated volumes as of December 31, 2013 and

The Company enters into oil and gas purchase transactions with third parties and separate sale transactions with third parties 
to satisfy unused pipeline capacity commitments and to diversify a portion of the Company's WTI oil sales to a Gulf Coast oil 
price.  Revenues and expenses from these transactions are presented on a gross basis as the Company acts as a principal in the 
transaction by assuming the risk and rewards of ownership, including credit risk, of the oil and gas purchased and assuming 
responsibility to deliver the oil and gas volumes sold. Deficiency payments on excess pipeline capacity are included in other 
expense  in  the  accompanying  consolidated  statements  of  operations.    See  Note  N  for  further  information  on  transportation 
commitment charges.

The Company recognized revenue of $42.1 million and $45.0 million during 2012 and 2011, respectively from volumetric 
production payment ("VPP") agreements which represented limited-term overriding royalty interests in oil reserves that: (i) entitled 
the purchaser to receive production volumes over a period of time from specific lease interests, (ii) were free and clear of all 
associated production costs and capital expenditures associated with the reserves, (iii) were nonrecourse to the Company (i.e., the 
purchaser's only recourse was to the reserves acquired), (iv) transferred title of the reserves to the purchaser and (v) allowed the 
Company to retain the remaining reserves after the VPPs volumetric quantities had been delivered.  The Company had no VPP 
obligations in 2013 as all VPP production volumes were delivered as of December 31, 2012; as such, the Company recognized no 
VPP revenue in 2013.

Derivatives. All derivatives are recorded in the accompanying consolidated balance sheets at estimated fair value. Effective 
February 1, 2009, the Company discontinued hedge accounting on all of its then-existing hedge contracts. The effective portions 
of the discontinued deferred hedges as of February 1, 2009 were included in accumulated other comprehensive income (loss) 
("AOCI - Hedging") and were transferred to earnings during the same periods in which the forecasted hedged transactions were 
recognized in the Company's earnings. During 2012, the remaining AOCI - Hedging losses were transferred to earnings.  Since 
discontinuing hedge accounting, the Company has recognized all changes in the fair values of its derivative contracts as gains or 
losses in the earnings of the periods in which they occur.  

The Company classifies the fair value amounts of derivative assets and liabilities executed under master netting arrangements 
as net current or noncurrent derivative assets or net current or noncurrent derivative liabilities, whichever the case may be, by 
commodity and counterparty. Net derivative asset values are determined, in part, by utilization of the derivative counterparties' 
credit-adjusted risk-free rate curves and net derivative liabilities are determined, in part, by utilization of the Company's and, 
through the date of the merger, Pioneer Southwest's credit-adjusted risk-free rate curves. The credit-adjusted risk-free rate curves 
for the Company and the counterparties are based on their independent market-quoted credit default swap rate curves plus the 
United States Treasury Bill yield curve as of the valuation date. Pioneer Southwest's credit-adjusted risk-free rate curve was based 
on independent market-quoted forward London Interbank Offered Rate ("LIBOR") curves plus 162.5 basis points, representing 
Pioneer Southwest's estimated borrowing rate.  See Note E for additional information about the Company's derivative instruments.

Environmental. The Company's environmental expenditures are expensed or capitalized depending on their future economic 
benefit. Expenditures that relate to an existing condition caused by past operations and that have no future economic benefits are 
expensed. Expenditures that extend the life of the related property or mitigate or prevent future environmental contamination are 
capitalized. Liabilities for expenditures that will not qualify for capitalization are recorded when environmental assessment and/
or remediation is probable and the costs can be reasonably estimated. Such liabilities are undiscounted unless the timing of cash 
payments for the liability is fixed or reliably determinable. Environmental liabilities normally involve estimates that are subject 
to revision until settlement occurs.

Stock-based compensation. For stock-based compensation awards granted or modified, stock-based compensation expense 
is being recognized in the Company's financial statements on a straight line basis over the awards' vesting periods based on their 
fair values on the dates of grant or modification, as applicable. The stock-based compensation awards generally vest over a period 
not exceeding three years. The amount of stock-based compensation expense recognized at any date is approximately equal to the 
ratable portion of the grant date value of the award that is vested at that date. The Company utilizes (i) the Black-Scholes option 
pricing model to measure the fair value of stock options, (ii) the prior day's closing stock price on the date of grant for the fair 
value of restricted stock, restricted stock units, partnership unit awards or phantom unit awards that are expected to be settled in 
the Company's common stock ("Equity Awards"), (iii) the Monte Carlo simulation method for the fair value of performance unit 
awards and (iv) a probabilistic forecasted fair value method for Series B unit awards issued by Sendero.

Stock-based compensation liability awards are awards that are expected to be settled in cash on their vesting dates, rather 
than in equity shares or units ("Liability Awards"). Stock-based Liability Awards are recorded as accounts payable—affiliates 
based on the vested portion of the fair value of the awards on the balance sheet date. The fair values of Liability Awards are updated 
at each balance sheet date and changes in the fair values of the vested portions of the awards are recorded as increases or decreases 
to stock-based compensation expense.

Segments. Operating segments are defined as components of an enterprise that (i) engage in activities from which it may 
earn revenues and incur expenses (ii) for which separate operational financial information is available and is regularly evaluated 
by the chief operating decision maker for the purpose of allocating resources and assessing performance.  

Based upon how the Company is organized and managed, the Company has only one reportable operating segment, which 
is oil and gas exploration and production. The Company considers its vertical integration services as ancillary to its oil and gas 

82

exploration and producing activities and manages these services to support such activities. In addition, the Company has a single, 
company-wide management team that allocates capital resources to maximize profitability and measures financial performance 
as a single enterprise.

Assets held for sale and discontinued operations. On the date at which the Company meets all the held for sale criteria, 
the Company discontinues the recording of depletion and depreciation of the assets or asset group to be sold and reclassifies the 
assets and related liabilities to be sold as held for sale on the accompanying consolidated balance sheets. The assets and liabilities 
are measured at the lower of their carrying amount or estimated fair value less cost to sell.  

In addition, after determining that held for sale criteria has been met, the Company considers whether the held for sale assets 
meet the criteria to be considered discontinued operations.  If the assets held for sale are considered discontinued operations, the 
Company classifies the results of operations from the assets held for sale as income or loss from discontinued operations, net of 
tax in the accompanying consolidated statements of operations for the current period and all prior periods.  See Note C for additional 
information about the Company's divestitures.

New accounting pronouncements.  In July 2013, the Financial Accounting Standards Boards issued Accounting Standards 
Update ("ASU") 2013-11, "Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax 
Loss, or a Tax Credit Carryforward Exists," which provides guidance on the presentation of unrecognized tax benefits.  The adoption 
of ASU 2013-11 during the third quarter of 2013 did not have a material impact on the Company's financial position and had no 
impact on the Company's statements of operations or cash flows.

NOTE C.  Acquisitions and Divestitures 

Pioneer Southwest Merger Transaction

On December 17, 2013, the Company completed the acquisition of all of the outstanding common units of Pioneer Southwest 
not already owned by the Company, through a merger of a wholly-owned subsidiary of the Company into Pioneer Southwest, the 
result of which was that Pioneer Southwest became a wholly-owned subsidiary of the Company. The merger was effected pursuant 
to an Agreement and Plan of Merger dated August 9, 2013, as amended on October 25, 2013 (as amended, the "Merger Agreement"), 
and was approved by the holders of the common units of Pioneer Southwest at a special meeting held on December 17, 2013.

Pursuant to the Merger Agreement, all of the common units outstanding as of the closing of the merger except for the 
common units owned by the Company, were canceled and converted into the right to receive 0.2325 of a share of common stock 
of the Company per common unit (the "Conversion Ratio").  In lieu of receiving any fractional share of common stock to which 
any holder of the Pioneer Southwest's common units would otherwise have been entitled, after aggregating all fractions of shares 
to which such holder would be entitled, any fractional share was rounded up to a whole share of common stock of the Company. 
Consequently, in December 2013, the Company issued an aggregate of 3.96 million shares of its common stock to Pioneer Southwest 
unitholders.  The merger is expected to facilitate the Company's plans to fully and optimally develop the Company's properties in 
the Midland Basin in West Texas utilizing horizontal drilling and is expected to enhance the Company's organizational, operational 
and administrative efficiencies. 

On  December  18,  2013,  the  Company  caused  Pioneer  Southwest,  its  general  partner  and  all  of  Pioneer  Southwest's 
subsidiaries to be merged with and into a wholly-owned subsidiary of the Company, the result of which was that all common units 
of Pioneer Southwest were canceled and the Company no longer holds any common units.

Premier Silica Business Combination

On April 2, 2012, a wholly-owned subsidiary of the Company acquired an industrial sand mining business that is now named 
Premier Silica LLC ("Premier Silica").  Premier Silica's primary mine operations are in Brady, Texas.  The Brady mine facilities 
primarily produce, process and provide sand to the Company for use as proppant in its fracture stimulation of oil and gas wells in 
Texas.  Premier Silica's sand production that is in excess of the Company's sand needs for fracture stimulation and sand production 
that is not usable for fracture stimulation is primarily sold to third parties for industrial and recreational purposes.  The aggregate 
purchase price of Premier Silica was $297.1 million, including closing adjustments.  

Divestitures Recorded in Continuing Operations

During December 2013, the Company committed to a plan to sell the Company's majority interest in Sendero to Sendero's 
minority interest owner for $31.0 million, subject to negotiating a definitive sales agreement and the buyer completing its financing 

83

arrangements.  Associated with the planned sale of Sendero, the Company recorded a noncash loss of $25.5 million in other expense 
during December 2013 to reduce the carrying value of Sendero's net assets to their estimated fair value.  As part of the sales 
negotiations, the Company plans to commit to lease 12 Sendero rigs through December 31, 2015, and to lease eight Sendero rigs 
in 2016.  The Company has classified Sendero assets and liabilities as held for sale in the accompanying consolidated balance 
sheet as of December 31, 2013.

The Company recorded net gains on disposition of assets in continuing operations of $209.0 million and $45.9 million 
during the years ended December 31, 2013 and 2012, respectively, and a net loss on disposition of assets in continuing operations 
of $3.6 million during the year ended December 31, 2011.  The following describes the significant divestitures included in continuing 
operations:

• 

Southern  Wolfcamp.    In  January  2013,  the  Company  signed  an  agreement  with  Sinochem  Petroleum  USA  LLC 
("Sinochem"), a U.S. subsidiary of the Sinochem Group, an unaffiliated third party, to sell 40 percent of Pioneer's 
interest in 207,000 net acres leased by the Company in the horizontal Wolfcamp Shale play in the southern portion of 
the Spraberry field in West Texas for total consideration of $1.8 billion, including normal closing adjustments.  In May 
2013, the Company completed the sale to Sinochem for net cash proceeds of $623.8 million, including normal closing 
adjustments, resulting in a gain of $181.3 million related to the unproved property interests conveyed to Sinochem.  
Sinochem is paying the remaining $1.2 billion of the transaction price by carrying 75 percent of Pioneer's portion of 
ongoing drilling and facilities costs attributable to the Company's joint operations with Sinochem in the horizontal 
Wolfcamp Shale play. 

•  West Panhandle. During the first quarter of 2013, the Company completed a sale of its interest in unproved oil and gas 
properties adjacent to the Company's West Panhandle field operations for net cash proceeds of $38.1 million, which 
resulted in a gain of $22.4 million,

•  Eagle Ford Shale. In January 2012, the Company sold a portion of its interest in an unproved oil and gas property in 
the Eagle Ford Shale play to unaffiliated third parties for cash proceeds of $54.7 million, which resulted in a gain of 
$42.6 million. 

•  Other.  During 2013, 2012 and 2011, the Company sold other proved and unproved properties, inventory and other 
property and equipment and recorded net gains of $5.3 million and $3.3 million during 2013 and 2012, respectively, 
and a net loss of $3.6 million during 2011.

Discontinued Operations

Alaska.  During the fourth quarter of 2013, the Company committed to a plan to sell 100 percent of the capital stock in 
Pioneer's Alaska subsidiary, representing all the Company's net assets in Alaska ("Pioneer Alaska").  The sale of Pioneer Alaska 
continues  to  be  subject  to  ongoing  negotiations  and  certain  other  conditions,  such  as  governmental  approvals  and  buyer's 
arrangement of financing.  

The Company has classified (i) Pioneer Alaska assets and liabilities as held for sale in the accompanying consolidated 
balance sheet as of December 31, 2013 and (ii) Pioneer Alaska results of operations as income (loss) from discontinued operations, 
net  of  tax  in  the  accompanying  consolidated  statements  of  operations  (including  a  recasting  of  the  Pioneer Alaska  results  of 
operations for the years ended December 31, 2012 and 2011, which were originally classified as continuing operations).  

Associated with the planned sale of Pioneer Alaska, the Company recorded a noncash impairment charge of $539.8 million 
in discontinued operations during December 2013 to reduce the carrying value of Pioneer Alaska to its estimated fair value less  
costs to sell of $350.6 million. See Note D for additional information about the Pioneer Alaska impairment charge.  The recasting 
of Pioneer Alaska results includes the sale of the Company's interest in the Cosmopolitan Unit in the Cook Inlet of Alaska in August 
2012 to unaffiliated third parties for cash proceeds of $10.1 million, which, together with certain Company obligations assumed 
by the purchasers, resulted in a gain of $12.6 million. 

Barnett Shale.   During the fourth quarter of 2013, the Company committed to a plan to divest of its net assets in the Barnett 
Shale field in North Texas. The plan is expected to result in the sale of the Barnett Shale net assets during 2014. The Company 
has classified its (i) Barnett Shale assets and liabilities as held for sale in the accompanying consolidated balance sheet as of 
December 31, 2013 and (ii) Barnett Shale results of operations as income (loss) from discontinued operations, net of tax in the 
accompanying consolidated statements of operations (including a recasting of the Barnett Shale results of operations for the years 
ended December 31, 2012 and 2011, which were originally classified as continuing operations).

PIONEER NATURAL RESOURCES COMPANY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
December 31, 2013, 2012, and 2011

 Associated with the Company's plan to sell its net assets in the Barnett Shale field, the Company recorded a noncash 
impairment charge of $189.5 million in discontinued operations in December 2013 to reduce the carrying value of its net assets 
in the Barnett Shale field to their estimated fair value less costs to sell. See Note D for more information about the impairment of 
Barnett Shale net assets.  Also included in discontinued operations in 2013 is the sale of the Company's interest in certain proved 
and unproved oil and gas properties in the Barnett Shale field for net cash proceeds of $33.8 million, which resulted in a gain of 
$8.7 million on the unproved properties sold.

The  Company's  plans  to  sell  Pioneer Alaska  and  the  Barnett  Shale  net  assets  are  in  differing  stages  of  marketing  and 

negotiation.  No assurance can be given that the sales will be completed in accordance with the Company's plans. 

South Africa.  In December 2011, the Company committed to a plan to exit South Africa and initiated a process to divest 
its net assets in South Africa ("Pioneer South Africa").  During the first quarter of 2012, the Company agreed to sell its net assets 
in Pioneer South Africa to an unaffiliated third party, effective January 1, 2012, for $60.0 million of cash proceeds before normal 
closing and other adjustments, and the buyer's assumption of certain liabilities of the Company's South Africa subsidiaries. In 
August 2012, the Company completed the sale of Pioneer South Africa for net cash proceeds of $15.9 million, including normal 
closing adjustments for cash revenues and costs and expenses from the effective date through the date of the sale, resulting in a 
gain of $28.6 million.   The Company classified Pioneer South Africa's results of operations as income from discontinued operations, 
net of tax in the accompanying consolidated statements of operations. 

Tunisia. In February 2011, the Company sold 100 percent of the Company's share holdings in Pioneer Natural Resources 
Tunisia Ltd. and Pioneer Natural Resources Anaguid Ltd. (referred to in the aggregate as "Pioneer Tunisia") to an unaffiliated third 
party for cash proceeds of $802.5 million, including normal closing adjustments and excluding cash and cash equivalents sold, 
resulting in a gain of $645.2 million.  Accordingly, the Company has classified the results of operations of Pioneer Tunisia as 
discontinued operations, net of tax in the accompanying consolidated statements of operations.

NOTE D.    Fair Value Measurements

Fair value is defined as the price that would be received to sell an asset or the price paid to transfer a liability in an orderly 
transaction between market participants at the measurement date. Fair value measurements are based upon inputs that market 
participants use in pricing an asset or liability, which are characterized according to a hierarchy that prioritizes those inputs based 
on the degree to which they are observable. 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. The three input levels of the fair value hierarchy are as follows:

•  Level 1 – quoted prices for identical assets or liabilities in active markets.
•  Level 2 – quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or 
liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (e.g. 
interest rates) and inputs derived principally from or corroborated by observable market data by correlation or other 
means.

•  Level 3 – unobservable inputs for the asset or liability.

Assets and liabilities measured at fair value on a recurring basis.  The fair value input hierarchy level to which an asset 
or liability measurement in its entirety falls is determined based on the lowest level input that is significant to the measurement in 
its entirety.

The following tables present the Company's assets and liabilities that are measured at fair value on a recurring basis as of 

December 31, 2013 and 2012 for each of the fair value hierarchy levels:

Trading securities and deferred compensation plan assets. The Company's trading securities are comprised of securities 
that  are  both  actively  traded  and  not  actively  traded  on  major  exchanges. The  Company's  deferred  compensation  plan  assets 
represent investments in equity and mutual fund securities that are actively traded on major exchanges. These investments are 
measured based on observable prices on major exchanges. As of December 31, 2013 and 2012, substantially all of the significant 
inputs to these asset exchange values represented Level 1 independent active exchange market price inputs. Inputs for certain 
trading securities that are not actively traded on major exchanges were classified as Level 2 inputs.

Commodity derivatives. The Company's commodity derivatives represent oil, NGL and gas swap contracts, collar contracts 
and collar contracts with short puts. The Company's asset and liability measurements for its oil, NGL and gas swap, collar and 
collar contracts with short puts represent Level 2 inputs in the hierarchy priority. The Company utilizes discounted cash flow and 
option-pricing models for valuing its commodity derivatives.

The asset and liability values attributable to the Company's commodity derivatives were determined based on inputs which 
include (i) the contracted notional volumes, (ii) independent active market price quotes, (iii) the applicable estimated credit-adjusted 
risk-free rate yield curve and (iv) the implied rate of volatility inherent in the collar and collar contracts with short puts, which is 
based on active and independent market-quoted volatility factors.

Interest rate derivatives. The Company's interest rate derivative assets and liabilities as of December 31, 2013 and 2012 
represent interest rate swap contracts. The Company utilizes discounted cash flow models for valuing its interest rate derivatives. 
The net derivative values attributable to the Company's interest rate derivative contracts as of December 31, 2013 and 2012 are 
based  on  (i) the  contracted  notional  amounts,  (ii) LIBOR  rate  yield  curves  provided  by  counterparties  and  corroborated  with 
forward active market-quoted LIBOR yield curves and (iii) the applicable credit-adjusted risk-free rate yield curve. The Company's 
interest rate derivative liability measurements represent Level 2 inputs in the hierarchy priority.

Assets and liabilities measured at fair value on a nonrecurring basis.  Certain assets are measured at fair value on a 
nonrecurring basis.  These assets are not measured at fair value on any ongoing basis, but are subject to fair value adjustments in 
certain circumstances.  These assets can include long-lived assets that have been reduced to fair value when they are held for sale, 
inventory and proved and unproved oil and gas properties that are written down to fair value when they are impaired.  

Proved oil and gas properties. During 2013, 2012 and 2011, reductions in management's longer-term commodity price 
outlooks ("Management's Price Outlooks") provided indications of possible impairment of the Company's predominately dry gas 
properties in the Raton field in southeastern Colorado, the Barnett Shale field in North Texas and the Edwards Trend and Austin 
Chalk fields in South Texas. As a result of management's assessments, during the years ended December 31, 2013, 2012 and 2011, 
the Company recognized impairment charges to reduce the carrying values of the Raton field, the Barnett Shale field and the 
Edwards Trend/Austin Chalk fields, respectively, to their estimated fair values.  The impairment charge associated with the Barnett 
Shale field is reported in income (loss) from discontinued operations, net of tax in the accompanying consolidated statements of 
operations.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
December 31, 2013, 2012, and 2011

The Company calculated the fair values of the Raton field, the Barnett Shale field and the Edwards Trend/Austin Chalk 
fields proved properties using a discounted cash flow model.  Significant Level 3 assumptions associated with the calculation of 
discounted future cash flows included Management's Price Outlooks and management's outlooks for (i) production costs, (ii) 
capital expenditures, (iii) production and (iv) estimated proved reserves and risk-adjusted probable reserves.  Management's Price 
Outlooks are developed based on third-party longer-term commodity futures price outlooks as of each measurement date.  The 
expected future net cash flows were discounted using an annual rate of 10 percent to determine fair value.  

The following table presents the fair value and fair value adjustments (in millions) for the Company's 2013, 2012 and 2011 
proved property impairments, as well as the average oil price per barrel ("BBL") and gas price per British thermal unit ("MMBTU") 
utilized in respective Management's Price Outlooks:

It is reasonably possible that the estimate of undiscounted future net cash flows attributable to these or other properties may 
change in the future resulting in the need to impair their carrying values. The primary factors that may affect estimates of future 
cash flows are (i) future adjustments, both positive and negative, to proved and appropriate risk-adjusted probable and possible 
oil and gas reserves, (ii) results of future drilling activities, (iii) Management's Price Outlooks and (iv) increases or decreases in 
production and capital costs associated with these fields.

Assets classified as held for sale.   The Company records assets classified as held for sale at the lower of the asset's carrying 
amount or estimated fair value less costs to sell. The fair value of Pioneer Alaska is based on an estimated sale price based on 
ongoing negotiations, less costs to sell, and is further supported by the Company's discounted cash flow model for the Alaska 
proved properties using Level 3 inputs as discussed in the proved oil and gas properties section above.  The fair value of the Barnett 
Shale field assets is based upon a weighted average calculation that uses management inputs including an estimated sales price 
and a discounted cash flow model for the proved properties using Level 3 assumptions as discussed in the proved oil and gas 
properties section above. The fair value of the Sendero assets are based upon anticipated sales proceeds less costs to sell, which 
represent  a  Level  3  input  in  the  hierarchy  priority.   See  Note  C  for  additional  information  regarding  the  Company's  planned 
divestitures.

Unproved  oil  and  gas  properties.  During  December  2012,  the  Company  recorded  an  impairment  charge  to  reduce  the 
carrying value of unproved properties in the Barnett Shale field of $71.8 million (reported in income (loss) from discontinued 
operations, net of tax in the accompanying consolidated statements of operations).  The Company calculated the estimated fair 
value of the Barnett Shale unproved properties using significant Level 3 assumptions based on average lease bonuses per acre for 
its Barnett liquid-rich acreage, allocating no value to dry gas acreage as the Company does not intend to develop that acreage.  

Inventories. During December 2013, the Company recorded an impairment charge of $23.2 million to reduce the carrying 
value of its excess vertical well pipe inventory. The Company calculated the estimated fair value of the inventory using significant

$ 2,653,059

$ 3,018,830

$ 3,721,193

$ 4,555,770

Long-term debt includes the Company's credit facility and the Company's senior notes.  At December 31, 2012, long-term 
debt also included Pioneer Southwest's credit facility and the Company's 2.875% Convertible Senior Notes due 2038 ("Convertible 
Senior Notes"), which were both fully extinguished during 2013.  The fair value of debt is determined utilizing inputs that are 
Level 2 measurements in the fair value hierarchy.

Credit facilities. The fair values of the Company's and, through the date of the merger, Pioneer Southwest's credit facilities 
are calculated using a discounted cash flow model based on (i) forecasted contractual interest and fee payments, (ii) forward active 
market-quoted United States Treasury Bill rate (in the case of the Company's credit facility) or LIBOR (in the case of Pioneer 
Southwest's credit facility) yield curves and (iii) the applicable credit-adjustments.  

Senior notes. The Company's senior notes represent debt securities that are not actively traded on major exchanges. The 

fair values of the Company's senior notes are based on their periodic values as quoted on the major exchanges.

The  Company  has  other  financial  instruments  consisting  primarily  of  cash  equivalents,  receivables,  prepaid  expenses, 
payables and other current assets and liabilities that approximate fair value due to the nature of the instrument and relatively short 
maturities. Non-financial assets and liabilities initially measured at fair value include certain assets acquired and liabilities assumed 
in a business combination, goodwill and asset retirement obligations.

Concentrations of credit risk. As of December 31, 2013, the Company's primary concentration of credit risks are the risks 
of collecting accounts receivable – trade and the risk of counterparties' failure to perform under derivative obligations. See Note 
L for information regarding the Company's major customers.

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 E for additional information regarding the Company's derivative activities and information regarding derivative 
net assets and liabilities by counterparty.

NOTE E.     Derivative Financial Instruments

The Company utilizes commodity swap contracts, collar contracts and collar contracts with short puts to (i) reduce the effect 
of price volatility on the commodities the Company produces and sells or consumes, (ii) support the Company's annual capital 
budgeting and expenditure plans and (iii) reduce commodity price risk associated with certain capital projects. The Company also, 
from time to time, utilizes interest rate contracts to reduce the effect of interest rate volatility on the Company's indebtedness.

Oil production derivative activities. All material physical sales contracts governing the Company's oil production are tied 
directly to, or are highly correlated with, New York Mercantile Exchange ("NYMEX") West Texas Intermediate ("WTI") oil prices.  
The Company uses derivative contracts to manage oil price volatility and basis swap contracts to reduce basis risk between NYMEX 
prices and actual index prices at which the oil is sold.

Company's March through December 2014 production with a NYMEX roll price of $0.82 per BBL and 5,000 BBLs per day of 
the Company's 2015 production with a NYMEX roll price of $0.60 per BBL. Rollfactor swap contracts fix the difference between 
(i) each day's price per BBL of WTI for the first nearby month less (ii) the price per BBL of WTI for the second nearby NYMEX 
month, multiplied by .6667; plus (iii) each day's price per BBL of WTI for the first nearby month less (iv) the price per BBL of 
WTI for the third nearby NYMEX month, multiplied by .3333. 

NGL production derivative activities. All material physical sales contracts governing the Company's NGL production are 
tied directly or indirectly to either Mont Belvieu or Conway fractionation facilities' NGL component product posted prices. The 
Company uses derivative contracts to manage the NGL component product price volatility.

As of December 31, 2013, the Company had natural gasoline collar contracts with short put derivatives for 1,000 BBLs per 
day of 2014 production with a ceiling price of $109.50 per BBL, a floor price of $95.00 per BBL and short put price of $80.00 
per BBL; and ethane collar contracts for 3,000 BBLs per day of 2014 production with a ceiling price of $13.72 per BBL and a 
floor price of $10.78 per BBL.

Subsequent to December 31, 2013, the Company entered into propane swap contracts for 1,000 BBLs per day of March 
through December 2014 production with a price of $47.57 per BBL and 2,000 BBLs per day of April through October 2014 
production with a price of $48.51 per BBL.

Gas production derivative activities. All material physical sales contracts governing the Company's gas production are tied 
directly or indirectly to NYMEX Henry Hub ("HH") gas prices or regional index prices where the gas is sold. The Company uses 
derivative contracts to manage gas price volatility and basis swap contracts to reduce basis risk between HH prices and actual 
index prices at which the gas is sold.

Subsequent to December 31, 2013, the Company entered into additional basis swap contracts for 35,000 MMBTU per 
day of April through December 2014 production with a negative price differential of $0.27 per MMBTU between the 
relevant index price and the NYMEX price.

Marketing and basis transfer derivatives. Periodically, the Company enters into buy and sell marketing arrangements to 
fulfill firm pipeline transportation commitments. Associated with these marketing arrangements, the Company may enter into 
index swaps to mitigate price risk. As of December 31, 2013, the Company had no open marketing derivative positions. Subsequent 
to December 31, 2013, the Company entered into marketing gas index swap contracts for 20,000 MMBTU per day of March 2014 
volumes with a price differential of $0.34 per MMBTU, 10,000 MMBTU per day of April through October 2014 volumes with a 
price differential of $0.36 per MMBTU and 30,000 MMBTU per day of April through December 2014 volumes with a price 
differential of $0.30 per MMBTU.

Interest rates. During the second quarter of 2013, the Company terminated its interest rate derivative contracts that locked 
in a fixed forward annual interest rate of 3.21 percent, for a 10-year period ending in December 2025, on a notional amount of 
$250 million and received cash proceeds of $482 thousand.

As of December 31, 2013, the Company was a party to interest rate derivative contracts whereby the Company will receive 
a fixed interest rate of 3.95 percent in exchange for paying a floating interest rate comprised of the three-month LIBOR plus an 
average rate of 1.11 percent on a notional amount of $400 million through July 15, 2022.

Tabular disclosure of derivative financial instruments. All of the Company's derivatives are accounted for as non-hedge 
derivatives as of December 31, 2013 and December 31, 2012 and therefore all changes in the fair values of its derivative contracts 
are recognized as gains or losses in the earnings of the periods in which they occur.  The Company classifies the fair value amounts 
of derivative assets and liabilities as net current or noncurrent derivative assets or net current or noncurrent derivative liabilities, 
whichever  the  case  may  be,  by  commodity  and  counterparty.    The  Company  enters  into  derivatives  under  master  netting 
arrangements,  which,  in  an  event  of  default,  allows  the  Company  to  offset  payables  to  and  receivables  from  the  defaulting 
counterparty.

Alaska - Nuna.  The Company's Nuna project, which has $42.9 million of suspended project costs as of December 31, 
2013, includes the Nuna-1 exploration well that was drilled during 2012 to test the Torok formation and a second appraisal well 
that was drilled and logged during the first quarter of 2013. The Company flow-tested the Nuna-1 well during the second quarter 
of 2012 and again in the first quarter of 2013. The second appraisal well encountered a mechanical problem and could not be flow-
tested before the end of the winter drilling season. The results of the flow tests on the Nuna-1 well and the log data from the second 
Nuna well are both very encouraging.  The Company is currently conducting a front-end engineering design study to evaluate the 
potential for onshore production facilities to support the project.  The capitalized exploratory well costs associated with the Nuna 
project are classified as held for sale in the accompanying consolidated balance sheet as of December 31, 2013.

Alaska - Oooguruk.  As of December 31, 2012, the Company had $22.0 million of suspended well costs recorded for the 
K-13 well in the Alaska Oooguruk field.  Drilling on the K-13 well was completed during September 2011.  During well completion 
operations, subsurface damages were sustained.  The Company performed repairs to correct a subsurface safety valve and a tubing 
leak in the third quarter of 2013. These repairs enabled a production test in the fourth quarter of 2013, which had negative results.  
Based on the negative production test results, the Company has discontinued any future plans to complete and produce the well.  
Accordingly, an exploration and abandonment charge of $33.7 million was recorded in the fourth quarter of 2013 to write off the 
K-13 well's carrying value, which is included in loss from discontinued operations, net of tax in the accompanying consolidated 
statements of operations.

Credit  Facility.  During  December  2012,  the  Company  entered  into  the  First Amendment  to  the  Second Amended  and 
Restated 5-Year Revolving Credit Agreement (the "Credit Facility") with a syndicate of financial institutions that extended the 
maturity to December 20, 2017 and increased the aggregate loan commitments to $1.5 billion.  As of December 31, 2013, the 
Company had no outstanding borrowings under the Credit Facility. 

Borrowings under the Credit Facility may be in the form of revolving loans or swing line loans. Aggregate outstanding 
swing line loans may not exceed $150 million. Revolving loans under the Credit Facility bear interest, at the option of the Company, 
based on (a) a rate per annum equal to the higher of the prime rate announced from time to time by Wells Fargo Bank, National 
Association or the weighted average of the rates on overnight Federal funds transactions with members of the Federal Reserve 
System during the last preceding business day plus 0.5 percent plus a defined alternate base rate spread margin, which is currently 
0.5 percent based on the Company's debt rating or (b) a base Eurodollar rate, substantially equal to LIBOR, plus a margin (the 
"Applicable Margin"), which is currently 1.50 percent and is also determined by the Company's debt rating. Swing line loans under 
the Credit Facility bear interest at a rate per annum equal to the "ASK" rate for Federal funds periodically published by the Dow 
Jones Market Service plus the Applicable Margin. Letters of credit outstanding under the Credit Facility are subject to a per annum 
fee, representing the Applicable Margin plus 0.125 percent. The Company also pays commitment fees on undrawn amounts under 
the Credit Facility that are determined by the Company's debt rating (currently 0.25 percent). Borrowings under the Credit Facility 
are general unsecured obligations.

The Credit Facility requires the maintenance of a ratio of total debt to book capitalization, subject to certain adjustments, 

not to exceed .60 to 1.0. As of December 31, 2013, the Company was in compliance with all of its debt covenants.

Upon completion of the Pioneer Southwest merger, the Company repaid the outstanding indebtedness and terminated the 
Pioneer Southwest $300 million Amended and Restated 5-Year Revolving Credit Agreement ("the "Pioneer Southwest Credit 
Facility"). Associated therewith, the Company charged $861 thousand of unamortized deferred financing fees related to the Pioneer 
Southwest Credit Facility to other expense in the accompanying consolidated statements of operations.

Senior notes. During June 2012, the Company issued $600 million of 3.95% Senior Notes due 2022 and received proceeds, 
net of $8.5 million of offering discounts and costs, of $591.5 million.  The Company used the net proceeds from the issuance to 
reduce outstanding borrowings under the Credit Facility.

The Company's senior notes are general unsecured obligations ranking equally in right of payment with all other senior 
unsecured indebtedness of the Company and are senior in right of payment to all existing and future subordinated indebtedness 
of the Company. The Company is a holding company that conducts all of its operations through subsidiaries; consequently, the 
senior notes are structurally subordinated to all obligations of its subsidiaries. Interest on the Company's senior notes is payable 
semiannually.

Convertible  senior  notes. As  of  December  31,  2012,  the  Company  had  $479.9  million  of  Convertible  Senior  Notes 
outstanding.  During December 2012 and March 2013, the Company's stock price met the price threshold that caused the Convertible 
Senior Notes to be convertible during the six months ended June 30, 2013 at the option of the holders into a combination of cash 
and the Company's common stock based on a formula set forth in the indenture supplement pursuant to which the Convertible 
Senior Notes were issued.  In addition, on April 15, 2013, the Company announced that it would exercise its option to redeem all 
Convertible Senior Notes that had not been converted by the holders before May 16, 2013. Associated therewith, during the six 
months ended June 30, 2013, holders of $479.1 million principal amount of the Convertible Senior Notes exercised their right to 
convert their Convertible Senior Notes into cash and shares of the Company's common stock.  The Company paid the tendering 
holders $479.1 million of cash and issued to the tendering holders 4.4 million shares of the Company's common stock during the 
six months ended June 30, 2013, in accordance with the terms of the Convertible Senior Notes indenture agreement.  On May 16, 
2013, the Company paid $845 thousand in principal and interest to redeem all Convertible Senior Notes that remained outstanding.  

For the years ended December 31, 2013, 2012 and 2011, the Company recorded $9.4 million, $33.5 million and $32.3 
million, respectively, of interest expense relating to the Convertible Senior Notes, which had an effective interest rate of 6.75 
percent.

NOTE H.     Incentive Plans

Retirement Plans

Deferred compensation retirement plan. In August 1997, the Compensation Committee of the Company's board of directors 
(the "Board") approved a deferred compensation retirement plan for the officers and certain key employees of the Company. Each 
officer and key employee is allowed to contribute up to 25 percent of their base salary and 100 percent of their annual bonus. The 
Company will provide a matching contribution of 100 percent of the officer's and key employee's contribution limited to the first 
ten percent of the officer's base salary and eight percent of the key employee's base salary. The Company's matching contribution 
vests immediately. A trust fund has been established by the Company to accumulate the contributions made under this retirement 
plan. The Company's matching contributions were $2.7 million, $2.4 million and $2.2 million for the years ended December 31, 
2013, 2012 and 2011, respectively.

401(k)  plan. The  Pioneer  Natural  Resources  USA,  Inc.  ("Pioneer  USA,"  a  wholly-owned  subsidiary  of  the  Company)            

401(k)  and  Matching  Plan  (the  "401(k)  Plan")  is  a  defined  contribution  plan  established  under  the  Internal  Revenue  Code 
Section 401. All regular full-time and part-time employees of Pioneer USA are eligible to participate in the 401(k) Plan on the 
first day of the month following their date of hire. Participants may contribute an amount up to 80 percent of their annual salary 
into the 401(k) Plan. Matching contributions are made to the 401(k) Plan in cash by Pioneer USA in amounts equal to 200 percent 
of a participant's contributions to the 401(k) Plan that are not in excess of five percent of the participant's base compensation (the 
"Matching Contribution"). Each participant's account is credited with the participant's contributions, Matching Contributions and 
allocations of the 401(k) Plan's earnings. Participants are fully vested in their account balances except for Matching Contributions 
and their proportionate share of 401(k) Plan earnings attributable to Matching Contributions, which proportionately vest over a 
four-year period that begins with the participant's date of hire. During the years ended December 31, 2013, 2012 and 2011, the 
Company recognized compensation expense of $29.7 million, $24.7 million and $18.3 million, respectively, as a result of Matching 
Contributions.

Stock-based compensation costs. In accordance with GAAP, the Company records stock-based compensation expense, 
equal to the fair value of share-based payments, ratably over the vesting periods of the Long-Term Incentive Plan ("LTIP") awards, 
the Pioneer Southwest Long-Term Incentive Plan ("Pioneer Southwest LTIP") awards, the Series B unit awards issued by Sendero 
and for payments associated with the Company's Employee Stock Purchase Plan ("ESPP").

Pioneer Long-Term Incentive Plan

In May 2006, the Company's stockholders approved the LTIP, which provides for the granting of various forms of awards, 
including stock options, stock appreciation rights, performance units, restricted stock and restricted stock units to directors, officers 
and employees of the Company. The LTIP provides for the issuance of 9.1 million shares pursuant to awards under the plan. The 
shares to be delivered under the LTIP shall be made available from (i) authorized but unissued shares, (ii) shares held as treasury 
stock or (iii) previously issued shares reacquired by the Company, including shares purchased on the open market.

The following table shows the number of shares available for issuance pursuant to awards under the Company's LTIP at

stock as compensation to directors, officers and employees of the Company (including 250,641 shares or units representing Liability 
Awards). The Company's issued shares, as reflected in the consolidated balance sheets as of December 31, 2013, do not include

$67.7 million, $137.2 million and $98.6 million, respectively, based on the market price on the vesting date.

As of December 31, 2013 and 2012, accounts payable – due to affiliates in the accompanying consolidated balance sheet 
includes $33.0 million and $18.8 million of liabilities attributable to the Liability Awards, representing the earned portion of the 
fair value of the outstanding awards as of that date.  The fair value of shares for which restrictions lapsed during 2013, 2012 and 
2011 was $26.1 million, $14.2 million and $6.7 million respectively, based on the market price on the vesting date.  

Stock option awards. Certain employees may be granted options to purchase shares of the Company's common stock with 
an exercise price equal to the fair market value of Pioneer common stock on the date of grant. The fair value of stock option awards 
is determined using the Black-Scholes option-pricing model. Option awards have a ten-year contract life. The expected life of an 
option  is  estimated  based  on  historical  and  expected  exercise  behavior. The  volatility  assumption  was  estimated  based  upon 
expectations of volatility over the life of the option as measured by historical volatility. The risk-free interest rate was based on 
the United States Treasury rate for a term commensurate with the expected life of the option. The dividend yield was based upon 
a seven-year average dividend yield.

Performance  unit  awards.  During  2013,  2012  and  2011,  the  Company  awarded  performance  units  to  certain  of  the 
Company's officers under the LTIP. The number of shares of common stock to be issued is determined by comparing the Company's 
total shareholder return to the total shareholder return of a predetermined group of peer companies over the performance period. 
The performance unit awards vest over a 34-month service period. The grant-date fair values per unit of the 2013, 2012 and 2011 
performance unit awards are $189.23, $172.57 and $134.68, respectively, which amounts were determined using the Monte Carlo 
simulation method and are being recognized as stock-based compensation expense ratably over the performance period. The Monte 
Carlo simulation model utilizes multiple input variables that determine the probability of satisfying the market condition stipulated 
in the award grant and calculates the fair value of the award. 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 United States 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 2013, 2012 and 2011:

compared to peer companies at the vesting date.

(b)  On December 31, 2013, the service period lapsed on 40,969 of these performance unit awards. The lapsed units earned 2.5 
shares for each vested award representing 102,424 aggregate shares of common stock issued on January 2, 2014. 

 The fair value of shares for which restrictions lapsed during 2013, 2012 and 2011 was $18.9 million, $18.8 million and 

$44.7 million, respectively, based on the market price on the vesting date.

Pioneer 2008 PSE Employee Long-Term Incentive Plan

In May 2008, the board of directors of the general partner (the "General Partner") of Pioneer Southwest adopted the Pioneer 
Southwest 2008 Long-Term Incentive Plan ("Pioneer Southwest LTIP"), which provides for the granting of various forms of unit-
based awards.  In connection with the Pioneer Southwest merger the Company has, effective as of December 17, 2013, assumed, 
adopted and amended the Pioneer Southwest LTIP, and has changed the name of such plan to the Pioneer 2008 PSE Employee 
Long-Term Incentive Plan ("PSE LTIP"), and has assumed all Pioneer Southwest obligations associated with the Pioneer Southwest 
LTIP existing prior to its assumption and adoption by the Company. The Pioneer Southwest LTIP limits the number of awards 
granted  under  the  plan  to  3.0  million  common  units  of  Pioneer  Southwest.   As  of  the  date  of  the  Pioneer  Southwest  merger, 
2.9 million common units under the Pioneer Southwest LTIP were available to be awarded or remained outstanding (678,034 
common shares of Pioneer based upon the Conversion Ratio) and are carried forward to the PSE LTIP.  The only outstanding 
awards under the PSE LTIP at the time of the Pioneer Southwest merger and immediately prior to the assumption and adoption of 
the PSE LTIP by the Company were phantom units of Pioneer Southwest. All such outstanding phantom units were converted at 
the effective time of the Pioneer Southwest merger based on the Conversion Ratio into restricted stock units of the Company, 
subject to the vesting schedule determined by the grant under the Pioneer Southwest LTIP which is a three-year vesting period 
from the date of grant.  The common shares of Pioneer to be delivered under the PSE LTIP shall be made available from (i) 
authorized but unissued shares, (ii) shares held as treasury stock or (iii) previously issued shares reacquired by the Company, 
including shares purchased on the open market.

Subsidiary Issuances of Unit-Based Compensation

During 2010, Sendero entered into restricted unit agreements with two key employees, granting 1,000 Series B units in 
Sendero. The Series B unit awards had a grant date fair value of $5.1 million, vest ratably over a five year service period and do 
not earn equity rights unless certain defined performance conditions are achieved by Sendero.

Employee Stock Purchase Plan

The Company has an ESPP that allows eligible employees to annually purchase the Company's common stock at a discounted 
price. Officers of the Company are not eligible to participate in the ESPP. Contributions to the ESPP are limited to 15 percent of 
an employee's pay (subject to certain ESPP limits) during the eight-month offering period (January 1 to August 31). Participants 
in the ESPP purchase the Company's common stock at a price that is 15 percent below the closing sales price of the Company's 
common stock on either the first day or the last day of each offering period, whichever closing sales price is lower.

Postretirement Benefit Obligations

At December 31, 2013 and 2012, the Company had $7.6 million and $9.7 million, respectively, of unfunded accumulated 
postretirement benefit obligations. These obligations are comprised of five unfunded plans, of which four relate to predecessor 
entities that the Company acquired in prior years, and two funded plans that the Company assumed sponsorship of in conjunction 
with the acquisition of Premier Silica.  Other than the Company's retirement plan and the two legacy-Premier Silica plans, the 
participants of these plans are not current employees of the Company. The unfunded plans had no assets as of December 31, 2013 
or 2012.   

NOTE I.    Asset Retirement Obligations

The Company's asset retirement obligations primarily relate to the future plugging and abandonment of wells and related 
facilities.  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 following table

 _____________________
(a) 

The changes in the 2013, 2012 and 2011 estimates are primarily due to increases in abandonment cost estimates based on 
recent actual costs incurred to abandon wells and declines in credit-adjusted risk-free discount rates used to value increases 
in asset retirement obligations. The increases in 2013 and 2011 estimates were partially offset by higher commodity prices, 
which had the effect of lengthening the economic life of certain wells and decreasing the present value of future retirement 
obligations. The increase in the 2012 estimate was further impacted by declines in oil, NGL and gas prices used to calculate 
proved reserves, which had the effect of shortening the economic life of certain wells and increasing the present value of 
future retirement obligations. 

(b)  Accretion of discount from integrated services includes Premier Silica accretion expense, which is recorded as a reduction 
in income from vertical integration services in interest and other income in the Company's accompanying consolidated 
statements of operations.  See Note M for more information about interest and other income.

As of December 31, 2013 and 2012, the current portions of the Company's asset retirement obligations were $19.3 million 

and $13.3 million, respectively. 

NOTE J.  Commitments and Contingencies

Severance agreements. The Company has entered into severance and change in control agreements with its officers and 
certain key employees. The current annual salaries for the officers and key employees covered under such agreements total $43.2 
million. 

Indemnifications. The Company has agreed to indemnify its directors and certain of its officers, employees and agents with 
respect to claims and damages arising from acts or omissions taken in such capacity, as well as with respect to certain litigation.

Legal actions. The Company is party to various proceedings and claims incidental to its business. While many of these 
matters involve inherent uncertainty, the Company believes that the amount of the liability, if any, ultimately incurred with respect 
to such other proceedings and claims will not have a material adverse effect on the Company's consolidated financial position as 
a whole or on its liquidity, capital resources or future annual results of operations. The Company records reserves for contingencies 
when information available indicates that a loss is probable and the amount of the loss can be reasonably estimated. 

Lawsuits filed in state and federal courts in Texas relating to the Pioneer Southwest merger.  On May 15, 2013, David 
Flecker, a purported unitholder of Pioneer Southwest, filed a class action petition on behalf of Pioneer Southwest's unitholders 
and a derivative suit on behalf of Pioneer Southwest against the Company, Pioneer USA, the General Partner and the directors of 
the General Partner, in the 134th Judicial District of Dallas County, Texas (the "Flecker Lawsuit"). A similar class action petition 
and derivative suit was filed against the same defendants on May 20, 2013, in the 160th Judicial District of Dallas County, Texas, 
by purported unitholder Vipul Patel (the "Patel Lawsuit").  On September 3, 2013, the court consolidated the Patel Lawsuit into 
the Flecker Lawsuit (as consolidated, the "Texas State Court Lawsuit"), and the plaintiffs filed a consolidated derivative and class 
action petition on September 5, 2013.

The Texas State Court Lawsuit alleges, among other things, that the consideration offered by the Company in the Pioneer 
Southwest merger was unfair and inadequate and that, by pursuing a transaction that was the result of an allegedly conflicted and 
unfair process, the defendants breached their duties under Pioneer Southwest's partnership agreement as well as the implied covenant 
of good faith and fair dealing, and engaged in self-dealing. Specifically, the lawsuit alleges that the director defendants: (i) engaged 
in self-dealing, failed to act in good faith toward Pioneer Southwest, and breached their duties owed to Pioneer Southwest; (ii) 
failed to properly value Pioneer Southwest and its various assets and operations and ignored or failed to protect against the numerous 
conflicts of interest arising out of the proposed transaction; and (iii) breached the implied covenant of good faith and fair dealing 
by engaging in a flawed merger process. The Texas State Court Lawsuit also alleges that the Company, Pioneer USA and the 
General Partner aided and abetted the director defendants in their purported breach of fiduciary duties. Based on these allegations, 
the plaintiffs in the Texas State Court Lawsuit seek to have the Pioneer Southwest merger rescinded. The plaintiffs also seek money 
damages and attorneys' fees. The defendants have filed a motion to dismiss the Texas State Court Lawsuit based on improper 
forum.

In September 2013, representatives of the plaintiffs in the Texas State Court Lawsuit and the defendants entered into a 
memorandum of understanding (the "Memorandum of Understanding") to settle the claims and allegations made in the lawsuit. 
The Memorandum of Understanding provided the plaintiffs with a period of confirmatory discovery during which the plaintiffs 
could confirm the fairness and reasonableness of the settlement contemplated by the Memorandum of Understanding.  As part of 
the  consideration  for  the  settlement,  the  Merger Agreement  was  amended  to  provide  for  contractual  appraisal  rights  for  the 
unitholders. The parties to the Memorandum of Understanding agreed to use their reasonable best efforts to obtain the agreement 
of any plaintiffs filing similar lawsuits to become party to the Memorandum of Understanding and the related settlement, and it 
is a condition to the consummation of the final settlement that any such plaintiffs join the settlement or such similar lawsuits 
otherwise be dismissed with prejudice prior to the final approval of the settlement.  

On January 7, 2014, the defendants and representatives of the plaintiffs in the Texas State Court Lawsuit entered into a 
stipulation of settlement (the "Stipulation of Settlement").  The Stipulation of Settlement provides for a full and complete discharge, 
dismissal with prejudice, settlement and release of all claims, suits and causes of action by the plaintiffs (other than appraisal rights 
under the Merger Agreement) against the defendants and their representatives arising out of or relating to the allegations made in 
the Texas State Court Lawsuit and the Federal Lawsuits (as defined below), the Pioneer Southwest merger or any deliberations, 
negotiations, disclosures, omissions, press releases, statements or misstatements in connection therewith, any fiduciary or other 
obligations in respect of the merger or any alternative transaction or under Pioneer Southwest's partnership agreement, or any costs 
and expenses associated with settlement other than as provided in the Stipulation of Settlement.

On January 11, 2014, the 134th Judicial District, Dallas County, Texas (the "Court") entered a Preliminary Approval Order 
providing for, among other things, the scheduling of a settlement hearing to be held before the Court, George L. Allen, Sr. Courts 
Building, 600 Commerce Street, 6th Floor West (Old), Dallas, TX 75202, on March 17, 2014, at 9:30 a.m; the certification, for 
settlement purposes only, of a Class consisting of all persons who held Pioneer Southwest common units, either of record or 
beneficially, at any time during the period from and including May 6, 2013 to and including December 17, 2013, the date of 
consummation of the Pioneer Southwest merger, including any and all of their respective successors-in-interest, predecessors, 
representatives, trustees, executors, administrators, heirs, assigns, or transferees, and any person or entity acting for or on behalf 
of, or claiming under, any of them, and specifically including plaintiffs, but excluding defendants, their subsidiary companies, 
affiliates, assigns, members of their immediate families, and the legal representatives, heirs, successors, or assigns of any such 
excluded person.  All proceedings relating to the allegations made in the Texas State Court Lawsuit other than with respect to the 
104

settlement have been stayed, and the Court entered an injunction against the commencement or prosecution of any action by any 
member of the Class asserting any of the claims subject to the settlement.  There can be no assurance that a final settlement will 
be approved.

Former lawsuits relating to the Pioneer Southwest merger that have been dismissed  

United States District Court for the Northern District of Texas. On August 21, 2013, Allan H. Beverly, a purported unitholder, 
filed a class action complaint against Pioneer Southwest, the Company, Pioneer USA, MergerCo and the directors of the General 
Partner in the United States District Court for the Northern District of Texas (the "Beverly Lawsuit"). On September 13, 2013, 
Douglas Shelton, another purported unitholder, filed a class action complaint against the same defendants in the Beverly Lawsuit 
(as well as the General Partner) in the same court as the Beverly Lawsuit (the "Shelton Lawsuit" and with the Beverly Lawsuit, 
the “Federal Lawsuits”). The Beverly Lawsuit alleged that the defendants breached their fiduciary duties by agreeing to the merger 
by means of an unfair process and for an unfair price. Specifically, the lawsuit alleged that the director defendants: (i) failed to 
maximize the value of Pioneer Southwest to its public unitholders and took steps to avoid competitive bidding; (ii) failed to properly 
value Pioneer Southwest; and (iii) ignored or failed to protect against the numerous conflicts of interest arising out of the proposed 
transaction. The  Beverly  Lawsuit  also  alleged  that  the  Company,  Pioneer  USA  and  MergerCo  aided  and  abetted  the  director 
defendants in their purported breach of fiduciary duties. The Shelton Lawsuit made similar allegations to the Beverly Lawsuit, 
specifically: (i) that the Company, as controlling unitholder, failed to fulfill its fiduciary duties in connection with the merger 
because it purportedly could not establish that the proposed merger was the result of a fair process that would return a fair price 
to the unaffiliated unitholders of Pioneer Southwest; (ii) that the director defendants breached their fiduciary duties by failing to 
exercise due care and diligence in connection with the proposed merger because the proposed merger was purportedly not the 
result of a fair process that will return a fair price to the unaffiliated unitholders; and (iii) that the non-director defendants aided 
and abetted the director defendants in their purported breach of fiduciary duties. The plaintiffs in the Federal Lawsuits sought the 
same remedies as the plaintiffs in the Texas State Court Lawsuit. The representatives of the plaintiffs in the Federal Lawsuits are 
also parties to the Memorandum of Understanding. In accordance with the Memorandum of Understanding, the plaintiffs in the 
Beverly Lawsuit voluntarily dismissed all claims in the lawsuit on October 15, 2013, and the plaintiffs in the Shelton Lawsuit 
voluntarily dismissed all claims in the lawsuit on October 16, 2013.

Delaware Court of Chancery.  On September 23, 2013, Patrick Wilson, another purported unitholder, filed a class action 
petition on behalf of the unitholders against Pioneer USA, MergerCo, Pioneer Southwest, the General Partner and the directors of 
the General Partner in the Court of Chancery of the State of Delaware (the "Wilson Lawsuit"). The Wilson Lawsuit alleged that 
the director defendants breached their purported fiduciary obligations to the unitholders by engaging in a process that undervalued 
Pioneer  Southwest  and  which  allegedly  constituted  gross  negligence,  recklessness,  willful  misconduct,  bad  faith  or  knowing 
violations of law. Additionally, the Wilson Lawsuit alleged that the non-director defendants aided and abetted the purported breaches 
of fiduciary duties of the director defendants. The Wilson Lawsuit sought the same remedies as the plaintiffs in the Texas State 
Court Lawsuit and the Federal Lawsuits.  The plaintiff in the Wilson Lawsuit voluntarily dismissed that action on January 2, 2014.  
After participating in and receiving confirmatory discovery, the plaintiff in the Wilson Action has informed representatives of the 
plaintiffs in the Texas State Court Lawsuit that he intends to participate as a class member in the settlement.

The Company cannot predict the outcome of these or any other lawsuits that might be filed subsequent to the date of the 
filing of this Report, nor can the Company predict the amount of time and expense that will be required to resolve these lawsuits.  
See Note C for a description of the Merger Agreement.

Obligations  following  divestitures.  In April  2006,  the  Company  provided  the  purchaser  of  its Argentine  assets  certain 
indemnifications. The Company remains responsible for certain contingent liabilities related to such indemnifications, subject to 
defined  limitations,  including  matters  of  litigation,  environmental  contingencies,  royalty  obligations  and  income  taxes.  The 
Company has also retained certain liabilities and indemnified buyers for certain matters in connection with other divestitures, 
including the sale of its Canadian assets in 2007, the sale of Pioneer Tunisia in February 2011, the sale of Pioneer South Africa in 
August 2012, the planned sale of Alaska in 2014 and in connection with sales of joint interests. The Company does not believe 
that these obligations are probable of having a material impact on its liquidity, financial position or future results of operations.

Drilling  commitments.  The  Company  periodically  enters  into  contractual  arrangements  under  which  the  Company  is 
committed to expend funds to drill wells in the future. The Company also enters into agreements to secure drilling rig services, 
which require the Company to make future minimum payments to the rig operators. The Company records drilling commitments 
in the periods in which the well is drilled or rig services are performed.

commitments of up to 50,000 BOEPD through August 2017 that are related to the Company's Permian Basin operations. The 
Company does not expect to be able to fulfill all of its short-term and long-term delivery obligations from projected production 
of available reserves; consequently, the Company plans to purchase third party volumes to satisfy its commitment if it is economical 
to do so; otherwise, it will pay demand fees for commitment shortfalls.

the Company received $3.0 million, $2.3 million and $2.2 million of fixed payments and $16.4 million, $11.8 million and $8.4 
million of variable payments, respectively, from EFS Midstream. During 2013, the Company purchased other plant and equipment 
from EFS Midstream totaling $2.8 million. The Company also paid $1.9 million to purchase rights of way from EFS Midstream 
during 2011.

Hydrocarbon Gathering and Handling Agreement. During June 2010, the Company entered into the HGH Agreement with 
EFS Midstream. In accordance with the terms of the HGH Agreement, EFS Midstream is obligated to construct certain equipment 
and facilities capable of gathering, treating and transporting oil and gas production from the Eagle Ford Shale properties operated 
by the Company. The HGH Agreement also obligates the Company and its Eagle Ford Shale working interest partners to use the 
EFS Midstream gathering, treating and transportation equipment and facilities. In accordance with the terms of the HGH Agreement, 
the Company paid EFS Midstream $81.3 million, $58.5 million and $21.3 million of gathering and treating fees during 2013, 2012 
and 2011, respectively. Such amounts were expensed as oil and gas production costs in the accompanying consolidated statements 
of operations.

NOTE L.     Major Customers 

The Company's share of oil and gas production is sold to various purchasers who must be prequalified under the Company's 
credit risk policies and procedures. The Company records allowances for doubtful accounts based on the age of accounts receivables 
and the financial condition of its purchasers and, depending on facts and circumstances, may require purchasers to provide collateral 
or otherwise secure their accounts. 

The following purchasers individually accounted for ten percent or more of the Company's consolidated oil, NGL and gas 

revenues, including the revenues from discontinued operations, in at least one of the three years ended December 31, 2013:

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

have been determined for these entities or groups of entities. The tax returns and the amount of taxable income or loss are subject 
to examination by United States federal, state, local and foreign taxing authorities. The Company made current and estimated tax 
payments of $12.4 million, $32.3 million and $22.3 million (net of tax refunds) during 2013, 2012 and 2011, respectively. These 
payments and net refunds include tax payments related to Pioneer Tunisia's and Pioneer South Africa's operations of $9.8 million 
and $12.2 million during 2012 and 2011, respectively.  

The Company continually assesses both positive and negative evidence to determine whether it is more likely than not that 
deferred tax assets can be realized prior to their expiration. Pioneer monitors Company-specific, oil and gas industry and worldwide 
economic factors and assesses the likelihood that the Company's net operating loss carryforwards ("NOLs") and other deferred 
tax attributes in the United States, state, local and foreign tax jurisdictions will be utilized prior to their expiration.

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. As of December 31, 
2013, the Company had unrecognized tax benefits of $21.2 million resulting from net operating loss carryovers and alternative 
minimum tax credits obtained from the acquisition of Premier Silica.  The unrecognized tax benefit is recorded as a reduction of 
the associated deferred tax asset and, if recognized, would affect the annual effective tax rate.  The Company expects to resolve 
uncertainties regarding the unrecognized tax benefit within twelve months of December 31, 2013.  There were no unrecognized 
tax benefits as of December 31, 2012.

 With respect to income taxes, the Company's policy is to account for interest charges as interest expense and any penalties 
as other expense in the consolidated statements of operations. The Company files income tax returns in the United States federal 
jurisdiction, and various state and foreign jurisdictions. As of December 31, 2013, there are no proposed adjustments or uncertain 
positions in any jurisdiction that would have a significant effect on the Company's future results of operations or financial position. 
The Company's earliest open years in its key jurisdictions are as follows:

NOTE P.    Net Income Per Share Attributable To Common Stockholders

In the calculation of basic net income (loss) per share attributable to common stockholders, participating securities are 
allocated earnings based on actual dividend distributions received plus a proportionate share of undistributed net income attributable 
to common stockholders, if any, after recognizing distributed earnings. The Company's participating securities do not participate 
in undistributed net losses because they are not contractually obligated to do so. The computation of diluted net income (loss) per 
share attributable to common stockholders reflects the potential dilution that could occur if securities or other contracts to issue 
common stock that are dilutive were exercised or converted into common stock or resulted in the issuance of common stock that 
would then share in the earnings of the Company. During periods in which the Company realizes a loss from continuing operations 
attributable to common stockholders, securities or other contracts to issue common stock would not be dilutive to net loss per 
share and conversion into common stock is assumed not to occur. Diluted net income (loss) per share is calculated under both the 
two-class method and the treasury stock method and the more dilutive of the two calculations is presented. 

The Company's basic net income (loss) per share attributable to common stockholders is computed as (i) net income (loss)  
attributable to common stockholders, (ii) less participating share- and unit-based basic earnings (iii) divided by weighted average 
basic shares outstanding. The Company's diluted net income (loss) per share attributable to common stockholders is computed as 
(i) basic net income (loss) attributable to common stockholders, (ii) plus diluted adjustments to participating undistributed earnings 
(iii) divided by weighted average diluted shares outstanding (excluding shares held in treasury).

UNAUDITED SUPPLEMENTARY INFORMATION
December 31, 2013, 2012 and 2011

Proved 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 proved reserve estimates are inherently imprecise and that estimates of new discoveries are more imprecise than those of 
currently producing oil and gas properties. Accordingly, these estimates are expected to change as additional information becomes 
available in the future.

UNAUDITED SUPPLEMENTARY INFORMATION
December 31, 2013, 2012 and 2011

Revisions of previous estimates. At December 31, 2013, revisions of previous estimates are comprised of 319 MMBOE of 
proved undeveloped reserves that are no longer expected to be drilled and 11 MMBOE of negative revisions attributable to updated 
performance profiles and cost estimates, partially offset by 30 MMBOE of positive price revisions. The Company continues to 
shift its drilling activity in the Spraberry/Wolfcamp play in the Midland Basin of West Texas from vertical drilling to horizontal 
drilling.  The Company believes that replacing vertical drilling with horizontal drilling will enhance ultimate resource recoveries 
and improve rates of return per dollar invested.  As a result, Pioneer no longer expects to drill a significant number of its previously 
recorded vertical proved undeveloped locations.  Consequently, proved undeveloped reserves were reduced by 231 MMBOE 
associated with vertical drilling locations in the Spraberry/Wolfcamp.  This reduction in proved reserves is reflected in revisions 
of previous estimates.  Based on the limited horizontal drilling conducted by Pioneer to date in six Wolfcamp and Spraberry shale 
intervals across Pioneer's acreage position in the Spraberry/Wolfcamp field, sufficient production and well control data is not yet 
available to support the replacement of the vertical proved undeveloped reserves with horizontal proved undeveloped reserve 
additions.  Pioneer also removed an additional 88 MMBOE of proved undeveloped reserves that are primarily attributable to the 
announced divestitures of Pioneer's Alaska and Barnett Shale Combo assets (45 MMBOE) and previously recorded gas wells that 
are no longer expected to be drilled due to the reallocation of drilling capital to higher-rate-of-return oil wells. The December 31, 
2013 NYMEX price used for oil and gas reserve preparation based upon SEC guidelines was $96.82 per barrel of oil and $3.67 
per Mcf of gas, compared to $94.84 per barrel of oil and $2.76 per Mcf of gas at December 31, 2012.

At December 31, 2012, revisions of previous estimates are comprised of 82 MMBOE of negative price revisions and 27 
MMBOE of negative revisions due to updated performance profiles and cost estimates. The December 31, 2012 NYMEX price 
used for oil and gas reserve preparation based upon SEC guidelines was $94.84 per barrel of oil and $2.76 per Mcf of gas, compared 
to $96.13 per barrel of oil and $4.12 per Mcf of gas at December 31, 2011.

At December 31, 2011, revisions of previous estimates were comprised of 28 MMBOE of negative price revisions and 10 
MMBOE of negative revisions due to updated performance profiles and cost estimates. The December 31, 2011 NYMEX price 
used for oil and gas reserve preparation based upon SEC guidelines increased $16.85 per barrel of oil and decreased $0.25 per 
Mcf of gas from $79.28 per barrel of oil and $4.37 per Mcf of gas at December 31, 2010.

Extensions and discoveries. Extensions and discoveries at December 31, 2013, 2012 and 2011 are primarily comprised of 
discoveries and extensions in the Wolfcamp, Strawn, Atoka and Mississippian horizons in the Spraberry field and discoveries in 
the Eagle Ford Shale and Barnett Shale Combo plays.  

Sales of minerals-in-place. Sales of minerals-in-place in 2013, 2012 and 2011 are primarily related to the divestment of 40 
percent of the Company's interest in 207,000 net acres in the horizontal Wolfcamp Shale play in the southern portion of the Spraberry 
field in West Texas, Pioneer South Africa and Pioneer Tunisia, respectively. See Note C for additional information regarding the 
Company's divestitures and discontinued operations.

Purchases of minerals-in-place. Purchases of minerals-in-place during all years are primarily attributable to acquisitions 

in the Company's Spraberry field.

Improved recovery. Additions from improved recovery during 2012 and 2011 relate to recognizing secondary recovery 

reserves attributable to waterflooding the Nuiqsut horizon of the Alaskan Oooguruk development project.

As of December 31, 2013, the Company had 783 proved undeveloped well locations as compared to 3,810 and 4,599 at 
December 31, 2012 and 2011, respectively.  The Company has 26 proved undeveloped well locations (representing 2 MMBOE 
of proved reserves) that are scheduled to be drilled more than five years from their original date of booking.  All of these wells 
are scheduled to be drilled within five years of the December 31, 2009 effective date of the Commission's Final Rule on the 
Modernization of Oil and Gas Reporting.

The changes in proved undeveloped reserves during 2013 are comprised of the following items:

Revisions of previous estimates. Revisions of previous estimates are comprised of 319 MMBOE of proved undeveloped 
reserves that are no longer expected to be drilled, partially offset by 8 MMBOE of positive revisions attributable to updated 
performance profiles and cost estimates and 1 MMBOE of positive price revisions.  As described in revisions of previous estimates 
of  total  proved  reserves,  Pioneer  no  longer  expects  to  drill  a  significant  number  of  its  previously  recorded  vertical  proved 
undeveloped locations.  Consequently, proved undeveloped reserves were reduced by 231 MMBOE associated with vertical drilling 
locations in the Spraberry/Wolfcamp.  This reduction in proved reserves is reflected in revisions of previous estimates.  Based on 
the limited horizontal drilling conducted by Pioneer to date in six Wolfcamp and Spraberry shale intervals across Pioneer's acreage 
position in the Spraberry/Wolfcamp field, sufficient production and well control data is not yet available to support the replacement 
of the vertical proved undeveloped reserves with horizontal proved undeveloped reserve additions.  Pioneer also removed an

Extensions  and  discoveries.  Extensions  and  discoveries  are  primarily  comprised  of  extensions  and  discoveries  in  the 

Wolfcamp, Strawn, Atoka and Mississippian horizons in the Spraberry field and discoveries in the Eagle Ford Shale.

Sales of minerals-in-place. Sales of minerals-in-place are primarily related to the divestment of a 40 percent interest in 
207,000 net acres in the horizontal Wolfcamp Shale play in the southern portion of the Spraberry field in West Texas and sales in

Transfers to proved developed. Transfers to proved developed reserves represents those undeveloped proved reserves that 
moved to proved developed as a result of development drilling during 2013. During 2013, the Company incurred $1.5 billion of 
development costs and developed 11 percent of its proved undeveloped reserves.  See the following table for the Company's firm 
plans for future development expenditures.      

Within  the  Spraberry  field,  the  Company  uses  both  public  and  proprietary  geologic  data  to  establish  continuity  of  the 
formation and its producing properties. This included seismic data and interpretations (2-D, 3-D and micro seismic); open hole 
log information (both vertical and horizontally collected) and petrophysical analysis of the log data; mud logs; gas sample analysis; 
drill  cutting  samples;  measurements  of  total  organic  content;  thermal  maturity;  sidewall  cores  and  data  measured  from  the 
Company's internal core analysis facility. After the geologic area was shown to be continuous, statistical analysis of existing 
producing wells was conducted to generate areas of reasonable certainty at distances from established production. As a result of 
this analysis, proved undeveloped reserves for drilling locations within these areas of reasonable certainty were recorded during 
2013.

 While the Company expects, based on Management's Price Outlooks, that future operating cash flows will provide adequate 
funding for future development of its proved undeveloped reserves over the next five years, it may also use any combination of 
internally-generated cash flows, cash and cash equivalents on hand, availability under its credit facility, proceeds from the sale of 
joint  interests  and  nonstrategic  assets  or  external  financing  sources  to  fund  these  and  other  capital  expenditures,  including 
exploratory  drilling  and  acquisitions.  The  following  table  represents  the  estimated  timing  and  cash  flows  of  developing  the 
Company's proved undeveloped reserves as of December 31, 2013 (dollars in thousands):

Standardized Measure of Discounted Future Net Cash Flows

The standardized measure of discounted future net cash flows is computed by applying commodity prices used in determining 
proved reserves (with consideration of price changes only to the extent provided by contractual arrangements) to the estimated 
future production of proved reserves less estimated future expenditures (based on year-end estimated costs) to be incurred in 
developing and producing the proved reserves, discounted using a rate of ten 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 
gas properties plus available carryforwards and credits and applying the current tax rates to the difference. The discounted future 
cash flow estimates do not include the effects of the Company's commodity derivative contracts. Utilizing the first-day-of-the-
month commodity prices during the 12-month period ending on December 31, 2013, held constant over each derivative contract's 
term, the net present value of the Company's derivative contracts discounted at ten percent was a liability of $47.7 million at 
December 31, 2013.

Discounted future cash flow estimates like those shown below are not intended to represent estimates of the fair value of 
oil and gas properties. Estimates of fair value should also consider probable and possible reserves, anticipated future commodity 
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.

The following tables provide the standardized measure of discounted future cash flows as of December 31, 2013, 2012 and 

2011, as well as a rollforward in total for each respective year:

__________________
(a) 

The Company's changes in Standardized Measure attributable to production rates, timing and other primarily represent 
changes in the Company's estimates of when proved reserve quantities will be realized.  During the twelve months ended 
December 31, 2013, the Company's undiscounted future net cash flows from proved reserves declined; however, the timing 
of the recovery of the future net cash flows accelerated, partially due to the aforementioned removal of lower-return-on-
investment vertical well locations, resulting in an increase in Standardized Measure.  During the twelve months ended 
December  31,  2012  and  2011,  the  Company  increased  its  development  drilling  capital  plans,  which  had  the  effect  of 
accelerating the estimated timing of development and realization of undeveloped proved reserves.

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of disclosure controls and procedures. The Company's management, with the participation of its principal 
executive officer and principal financial officer, have evaluated, as required by Rule 13a-15(b) under the Securities Exchange Act 
of 1934 ("the Exchange Act"), the effectiveness of the Company's disclosure controls and procedures (as defined in Exchange Act 
Rule 13a-15(e)) as of the end of the period covered by this Report. Based on that evaluation, the principal executive officer and 
principal financial officer concluded that the Company's disclosure controls and procedures were effective, as of the end of the 
period covered by this Report, in ensuring that information required to be disclosed by the Company in the reports that it files or 
submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's 
rules and forms, including that such information is accumulated and communicated to the Company's management, including the 
principal executive officer and principal financial officer, to allow timely decisions regarding required disclosure.

Changes in internal control over financial reporting. There have been no changes in the Company's internal control over 
financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) that occurred during the three months ended December 
31, 2013 that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial 
reporting.

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  by  or  under  the  supervision  of  the 
Company's principal executive officer and principal financial officer and effected by the Board, management and other personnel 
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 generally accepted accounting principles.

The Company's management, with the participation of its principal executive officer and principal financial officer assessed 
the effectiveness, as of December 31, 2013, of the Company's internal control over financial reporting based on the criteria for 
effective internal control over financial reporting established in "Internal Control — Integrated Framework (1992)," issued by the 
Committee of Sponsoring Organizations of the Treadway Commission. Based on the assessment, management determined that 
the Company maintained effective internal control over financial reporting at a reasonable assurance level as of December 31, 
2013, based on those criteria.

Ernst & Young 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 an attestation report on the effectiveness of the Company's 
internal control over financial reporting as of December 31, 2013. The report, which expresses an unqualified opinion on the 
effectiveness of the Company's internal control over financial reporting as of December 31, 2013, is included in this Item under 
the heading "Report of Independent Registered Public Accounting Firm."

REPORT OF INDEPENDENT REGISTERED PUBLIC
ACCOUNTING FIRM

The Board of Directors and Stockholders of
Pioneer Natural Resources Company

We have audited Pioneer Natural Resources Company's (the "Company") internal control over financial reporting as of 
December  31,  2013,  based  on  criteria  established  in  Internal  Control—Integrated  Framework  issued  by  the  Committee  of 
Sponsoring  Organizations  of  the  Treadway  Commission  (1992  framework)  (the  COSO  criteria).  Pioneer  Natural  Resources 
Company's management is responsible for maintaining effective internal control over financial reporting, and for its assessment 
of the effectiveness of internal control over financial reporting included in the accompanying Management's Report on Internal 
Control Over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial 
reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United 
States). 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.

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.

In our opinion, Pioneer Natural Resources Company maintained, in all material respects, effective internal control over 

financial reporting as of December 31, 2013, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), 
the  consolidated  balance  sheets  of  Pioneer  Natural  Resources  Company  as  of  December  31,  2013  and  2012  and  the  related 
consolidated statements of operations, comprehensive income (loss), equity and cash flows for each of the three years in the period 
ended December 31, 2013, and our report dated February 26, 2014 expressed an unqualified opinion thereon.
