Mission and Strategies
The Company's mission is to be America's leading independent energy company, focused on value, safety, the environment, technology and its people. The Company's long-term strategy is centered around the following strategic objectives:
maintaining a strong balance sheet to ensure financial flexibility;
delivering economic production and proved reserve additions through drilling, completion and production improvement activities;
utilizing the Company's scale and technology advancements to reduce costs and improve efficiency;
reinvesting 50 percent to 60 percent of Company's operating cash flow, with the remaining cash flow targeted to debt reduction and returning cash to shareholders, primarily through dividends;
evaluating accretive acquisitions or acreage trades that enhance the Company's reinvestment framework and allow incremental cash flow to be returned to shareholders;
developing and training employees and contractors to perform their jobs in a safe manner; and
stewarding the environment through industry leading sustainable development efforts.
The Company's long-term strategy is anchored by the Company's interests in the long-lived Spraberry/Wolfcamp oil field located in the Permian Basin in West Texas, which has an estimated remaining productive life in excess of 45 years.
Competition
The oil and gas industry is highly competitive in the exploration for and acquisition of reserves, the acquisition of oil and gas leases, marketing of oil, NGL and gas production, the obtaining of equipment and services and the hiring and retention of staff necessary for the identification, evaluation, operation and acquisition and development of oil and gas properties. The Company's competitors include a large number of companies, including major integrated oil and gas companies, other independent oil and gas companies, and individuals engaged in the exploration for and development of oil and gas properties. The Company also faces competition from companies that supply alternative sources of energy, such as wind, solar power, and other renewables. Competition will increase as alternative energy technology becomes more reliable and governments throughout the world support or mandate the use of such alternative energy.

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. 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.
See "Item 1A. Risk Factors - The Company faces significant competition and some of its competitors have resources in excess of the Company's available resources" for additional information.
Impact of the COVID-19 Pandemic
A novel strain of the coronavirus ("COVID-19") surfaced in late 2019 and has spread around the world, including to the United States. In March 2020, the World Health Organization declared COVID-19 a pandemic, and the President of the United States declared the COVID-19 outbreak a national emergency. The COVID-19 pandemic has significantly affected the global economy, disrupted global supply chains and created significant volatility in the financial markets. In addition, the COVID-19 pandemic has resulted in travel restrictions, business closures and other restrictions that have disrupted the demand for oil throughout the world and when combined with pressures on the global supply-demand balance for oil and related products, resulted in significant volatility in oil prices beginning in late February 2020. The length of this demand disruption is unknown, and will ultimately depend on various factors beyond the Company's control, such as the duration and scope of the pandemic, the length and severity of the worldwide economic downturn, the ability of OPEC, Russia and other oil producing nations to manage the global oil supply, additional actions by businesses and governments in response to the pandemic, the speed and effectiveness of responses to combat the virus, including the effectiveness of the COVID-19 vaccines, and the time necessary to balance oil supply and demand. Additionally, there is significant uncertainty regarding the lasting impacts of the pandemic on global demand, as it cannot be predicted as to whether certain demand-reducing behaviors such as declines in business travel and changes in work-from-home practices will persist beyond the resolution of the pandemic. In response to these developments the Company has implemented measures to mitigate the impact of the COVID-19 pandemic on its employees, operations and financial position. These measures include, but are not limited to, the following:
Employee Health and Safety. The Company has taken steps to keep its employees safe in light of the COVID-19 pandemic by implementing preventative measures and developing response plans intended to minimize unnecessary risk of exposure and infection among its employees, as recommended by the Centers for Disease Control and Prevention (the "CDC"). The Company has also modified certain business practices (including those related to non-operational employee work locations, such as a significant reduction in business travel and physical participation in meetings, events and conferences) to conform to government restrictions and best practices encouraged by the CDC, and other governmental and regulatory authorities.
Expense Management. With the reduction in revenue associated with lower oil prices during 2020, the Company focused its efforts on:
Optimizing drilling, completion and operational efficiencies, resulting in lower well costs and operating costs and
Reducing general and administrative and other overhead related costs through:
a corporate restructuring to reduce the Company's staffing levels to correspond with a planned reduction in future activity levels, resulting in approximately 300 employees being involuntarily separated from the Company in October 2020 (the "2020 Corporate Restructuring");
voluntary salary reductions by the Company's officers and board of directors from March 2020 through December 2020;
reductions in 2020 cash incentive compensation;
2020 benefit reductions; and
other cash cost reductions.
Balance Sheet, Cash Flow and Liquidity. During 2020, the Company also took the following actions to strengthen its financial position and increase liquidity during the COVID-19 pandemic:
Reduced its 2020 capital budget by over 50 percent,
Enhanced its liquidity position by refinancing a portion of its existing debt and issuing new debt, with the combined objective of increasing liquidity, extending the Company's debt maturities and lowering the Company's future cash interest expense on long-term debt, and
Adjusted the Company's derivative positions to reduce the effects of oil price volatility on its net cash provided by operating activities.
The Company continues to assess the global impacts of the COVID-19 pandemic and may modify its plans as the health and economic impacts of COVID-19 continue to evolve.

See Note 5 and Note 7 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.
Acquisition Activities
The Company regularly seeks to acquire or trade acreage that complements its operations, provides exploration and development opportunities, increases the lateral length of future horizontal wells and provides superior returns on investment (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). The Company periodically evaluates and pursues acquisition and acreage trade opportunities 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, negotiations of letters of intent or negotiations of definitive agreements. The success of any acquisition or acreage trade is uncertain and depends on a number of factors, some of which are outside the Company's control.
On January 12, 2021, the Company acquired Parsley Energy, Inc., a Delaware corporation that previously traded on the NYSE under the symbol "PE" ("Parsley"), pursuant to the Agreement and Plan of Merger, dated as of October 20, 2020, among Pioneer, certain of its subsidiaries, Parsley and Parsley's subsidiary, Parsley Energy, LLC (the "Parsley Acquisition"). Although this Annual Report is being filed following the completion of the Parsley Acquisition, unless otherwise specifically noted, information set forth herein only relates to the period as of and for the fiscal year ended December 31, 2020 and therefore does not include information relating to Parsley or its subsidiaries as of and for such periods. Accordingly, unless otherwise specifically noted, references herein to "Pioneer" or the "Company" refer only to Pioneer and its subsidiaries prior to the Parsley Acquisition and do not include Parsley or its subsidiaries.
The Parsley Acquisition will be accounted for as a business combination, with the fair value of consideration allocated to the acquisition date fair value of assets and liabilities acquired. Parsley's post-acquisition date results of operations will be consolidated into the Company's interim consolidated financial statements beginning on January 12, 2021. See Note 19 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.
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, distance from the well to a major pipeline, commodity quality and prevailing supply and demand conditions. See "Item 7A. Quantitative and Qualitative Disclosures About Market Risk" for additional information.
Seasonal nature of business. Generally, but not always, the demand for gas decreases during the summer months and increases during the winter months. Seasonal anomalies such as mild winters or hot summers may impact general seasonal changes in demand.
Delivery commitments. The Company has committed certain volumes of oil, NGL and gas to customers under a variety of contracts, some of which have volumetric firm transportation or fractionation requirements that could require monetary shortfall penalties if the Company's transported or fractionation volumes are insufficient to satisfy associated commitments. See Note 11 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.
Significant purchasers. During 2020 the Company's oil, NGL and gas sales to Sunoco Logistics Partners L.P., Occidental Energy Marketing Inc. and Plains Marketing L.P accounted for 36 percent, 18 percent and 14 percent of the Company's oil and gas revenues, respectively. The loss of one of these significant purchasers or an inability to secure adequate pipeline, gas plant and NGL fractionation infrastructure for its Permian Basin production could have a material adverse effect on the Company's ability to produce and sell its oil, NGL and gas production.
Revenues from sales of purchased oil and gas to Occidental Energy Marketing Inc. accounted for 28 percent of the Company's sales of purchased oil and gas. No other sales customer exceeded ten percent of the Company's sales of purchased oil and gas during 2020. The loss of the Company's significant purchaser of purchased oil and gas would not be expected to have a material adverse effect on the Company's ability to sell commodities it purchases from third parties.
See Note 13 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.

PIONEER NATURAL RESOURCES COMPANY
Human Capital
At December 31, 2020, the Company had 1,853 employees, 698 of whom were employed in field operations and 256 of whom were employed in vertical integration activities. The Company understands that employee recruiting, retention and development play a critical role to the Company's business activities and its ability to achieve its long-term strategy. The Company offers a competitive compensation and benefits program and has established policies and talent development programs with the goal of creating an inclusive environment to allow all employees to feel respected, valued and connected to the business.
Compensation and benefits program. The Company annually reviews compensation for all employees to adjust compensation for market conditions and attract and retain a highly skilled workforce. The Company considers its employees to be its greatest asset and encourages them to take full advantage of the benefits and programs the Company offers. To ensure Pioneer attracts and retains top talent, the Company maintains an above-average benefits package. Pioneer's employees participate in incentive plans that take into consideration individual and Company performance through a traditional bonus plan that is influenced by individual performance and a variable compensation plan denominated in Company stock. In addition to cash and equity compensation, the Company also offers other employee benefits such as life and health (medical, dental & vision) insurance, paid time off, paid parental leave, flexible work schedules and a 401(k) plan.
Diversity and inclusion. The Company is committed to creating an inclusive environment where all employees feel respected, valued and connected to the business — a workplace to which individuals bring their "authentic" selves and can be successful in achieving their goals. The Company has established a variety of diversity and inclusion initiatives, such as OnePioneer, a single organization that was created in 2019 through the merger of Pioneer's various employee resource groups. OnePioneer is led by a diverse representation of the Company's employees who advance diversity and inclusion across the entire company.
Talent development. The Company's talent planning approach identifies and targets development for critical talent. The Company identifies critical roles based on several factors, including strategic importance, scope and impact, and unique skills. Successor candidates for those critical roles are then identified as those who have the interest, ability and experience to succeed in the critical role within five years. Talent planning enables Pioneer to proactively approach succession planning and offer targeted development for high potential employees and successors, while enabling a cross-functional view of talent to increase visibility and mobility.
Community involvement. Pioneer's dedication to community well-being and success shows in the many ways the Company seeks to be a good neighbor in all of its operating areas. The Company's employees continually seek out events, organizations, initiatives and partnerships to support, and the Company is honored to support their ongoing efforts to enrich the communities where they live and work, including through a charitable matching program.
Health, safety and environment. The Company maintains a culture of continuous improvement in safety and environmental practices, supports a diverse workforce and inspires teamwork to drive innovation, with oversight from the Health, Safety and Environment Committee and the Nominating and Corporate Governance Committee of the board of directors.
Regulation
The oil and gas industry is extensively regulated at the federal, state, and local levels. Regulations affecting elements of the energy sector are under constant review for amendment or expansion over time and frequently more stringent requirements are imposed. Various federal and state agencies, including the Texas Railroad Commission, the Bureau of Land Management (the "BLM"), the U.S. Environmental Protection Agency (the "EPA"), the U.S. Occupational Safety and Health Administration ("OSHA"), have legal and regulatory authority and oversight over the Company's exploration and development activities and operations. Other agencies with certain authority over the Company's business include the Internal Revenue Service (the "IRS"), the SEC and NYSE. Ensuring compliance with the rules, regulations and orders promulgated by such entities requires extensive effort and incremental costs to comply, which consequently affects the Company's profitability. Because public policy changes are commonplace, and existing laws and regulations are frequently amended, the Company is unable to predict the future cost or impact of compliance. However, the Company does not expect that any of these laws and regulations will affect its operations materially differently than they would affect other companies with similar operations, size and financial strength.
The following are significant areas of government control and regulation affecting the Company:
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 many requirements, including the

9

Table of Contents
PIONEER NATURAL RESOURCES COMPANY
responsibility for establishing and maintaining disclosure controls and procedures alongside 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 delisting 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 strives to conduct its operations in a socially and environmentally responsible manner and is required to comply with many federal, state and local laws, regulations and executive orders concerning occupational safety and health, the discharge or other release of materials and protection of the environment and natural resources. These environmental legal requirements primarily relate to:
the discharge or other release of pollutants into federal and state waters;
assessing the environmental impact of seismic acquisition, drilling or construction activities;
the generation, storage, transportation and disposal of waste materials, including hazardous substances;
the emission of certain gases, including GHGs, into the atmosphere;
the monitoring, abandonment, reclamation and remediation of well and other sites, including sites of former operations;
the development of emergency response and spill contingency plans;
the protection of threatened and endangered species; and
worker protection.

The more significant of these existing environmental and occupational health and safety laws and regulations include the following U.S. legal standards, as amended from time to time:
the Clean Air Act ("CAA"), which restricts the emission of air pollutants from many sources and imposes various pre construction, operational, monitoring and reporting requirements, and that the EPA has relied upon as authority for adopting climate change regulatory initiatives relating to GHG emissions;
the Federal Water Pollution Control Act, also known as the Clean Water Act ("CWA"), which regulates discharges of pollutants from facilities to state and federal waters and establishes the extent to which waterways are subject to federal jurisdiction and rulemaking as protected waters of the United States;
the Comprehensive Environmental Response, Compensation and Liability Act of 1980 ("CERCLA"), which imposes liability on generators, transporters, disposers and arrangers of hazardous substances at sites where hazardous substance releases have occurred or are threatening to occur;
the Resource Conservation and Recovery Act ("RCRA"), which governs the generation, treatment, storage, transport and disposal of solid wastes, including oil and gas exploration and production wastes and hazardous wastes;
the Safe Drinking Water Act ("SDWA"), which ensures the quality of the nation's public drinking water through adoption of drinking water standards and controlling the injection of waste fluids into below-ground formations that may adversely affect drinking water sources;
OSHA, which establishes workplace standards for the protection of the health and safety of employees, including the implementation of hazard communications programs designed to inform employees about hazardous substances in the workplace, potential harmful effects of these substances, and appropriate control measures; and
the Endangered Species Act ("ESA"), which restricts activities that may affect federally identified endangered and threatened species or their habitats through the implementation of operating restrictions or a temporary, seasonal or permanent ban in affected areas.
Additionally, there exist tribal, state and local jurisdictions where the Company operates that also have, or are developing or considering developing, similar environmental and occupational health and safety laws and regulations governing many of these same types of activities. Failure by the Company to comply with these laws, regulations and regulatory initiatives or controls may result in the assessment of sanctions, including administrative, civil and criminal penalties; the imposition of investigatory, remedial and corrective action obligations or the incurrence of capital expenditures; the occurrence of restrictions, delays or cancellations in the permitting, development or expansion of projects; and issuance of injunctions restricting or prohibiting some or all of our activities in a particular area. Historically, the Company's environmental and worker safety compliance costs have not had a material adverse effect on its results of operations. However, there can be no assurance that such costs will not be material in the future or that such future compliance will not have a material adverse effect on the Company's business and operational results.
The Company owns, leases or operates numerous properties that have been used for oil and gas exploration and production activities for many years. The Company also has acquired certain properties from third parties whose actions with

10

Table of Contents
PIONEER NATURAL RESOURCES COMPANY
respect to the management and disposal or release of hydrocarbons, hazardous substances or wastes at or from such properties were not under the Company's control prior to acquiring them. Under certain environmental laws and regulations such as CERCLA and RCRA, the Company could incur strict joint and several liability due to damages to natural resources or for remediating hydrocarbons, hazardous substances or wastes disposed of or released by prior owners or operators. Moreover, an accidental release of materials into the environment during the Company's operations may cause it to incur significant costs and liabilities. The Company also could incur costs related to the clean-up of third-party sites to which it sent regulated substances for disposal or to which it sent equipment for cleaning and for damages to natural resources or other claims related to releases of regulated substances at or from such third-party sites.

Over time, the trend in environmental and occupational health and safety laws and regulations is to typically place more restrictions and limitations on activities that may adversely affect the environment or expose workers to injury. If existing legal requirements change or new legislative, regulatory or executive initiatives are developed and implemented in the future, the Company may be required to make significant, unanticipated capital and operating expenditures. The Company may not have insurance or be fully covered by insurance against all environmental and occupational health and safety risks. For more information on environmental and occupational health and safety matters, see the risk factors identified as Health, Safety and Environmental Risks in Item 1A. Risk Factors.

Other regulation of the oil and gas industry. The Company's oil and gas operations are subject to laws and regulations that relate to matters including:
the acquisition of seismic data;
location, drilling and casing of wells;
hydraulic fracturing;
well production operations;
disposal of produced water;
regulation of transportation and sale of oil, NGLs and gas;
surface usage;
calculation and disbursement of royalty payments and production taxes;
restoration of properties used for oil and gas operations; and
transportation of production.
Development and production operations are subject to regulations including requiring permits for the drilling of wells, the posting of bonds in connection with various types of activities and filing reports concerning operations. Texas, and some 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 of drilling and spacing units or proration units governing the drilling and production of oil and gas properties. The Company relies on voluntary pooling, production sharing agreements and the drilling of allocation wells to develop its 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 and generally prohibit the venting or flaring of gas without a permit. These laws and regulations may limit the amount of oil and gas the Company can produce from the Company's wells, negatively affect the economic decision to continue to produce these wells or limit the number of wells or locations that the Company can economically drill.
Approximately one percent of the Company's U.S. oil and gas leases are granted or approved by the federal government and administered by the BLM. All of the Company's federal leases are outside of Texas and the Company has no current plans to further develop the leases at this time. Such leases require compliance with detailed federal regulations and orders that regulate, among other matters, drilling and operations on lands covered by these leases and calculation and disbursement of royalty payments to the federal government.

ITEM 1A.    RISK FACTORS
The Company's operations and financial results are subject to various risks and uncertainties, including but not limited to those described below. 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." 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 or 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 following risk factors are summarized as general business and industry, operational, financial, health, safety and environmental, regulatory risks and risks associated with the Parsley Acquisition.

General Business and Industry Risks
The COVID-19 pandemic and recent developments in the global oil markets have had, and may continue to have, material adverse consequences for general economic, business and industry conditions.
Declining general economic, business or industry conditions could have a material adverse effect on the Company's results of operations.
The Company may be unable to make attractive acquisitions and any acquisition it completes is subject to substantial risks that could materially and adversely affect its business.
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.
The Company's operations and drilling activity are concentrated in the Permian Basin of West Texas; such concentration makes the Company vulnerable to risks associated with operating in a limited geographic area.
The Company may not be able to obtain access on commercially reasonable terms or otherwise to pipelines and storage facilities, gathering systems and other transportation, processing, fractionation, refining and export facilities to market its oil, NGL and gas production.
The refining industry may be unable to absorb U.S. oil production; in such a case, the resulting surplus could depress prices and restrict the availability of markets.
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.
Because the Company's producing wells decline continually over time, the Company will need to mitigate these declines through drilling and production enhancement initiatives and/or acquisitions.
A portion of the Company's total estimated proved reserves at December 31, 2020 were undeveloped, and those proved reserves may not ultimately be developed.
The Company faces significant competition and some of its competitors have resources in excess of the Company's available resources.
The Company's business could be materially and adversely affected by security threats, including cybersecurity threats, and other disruptions.
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.
The Company has identified a material weakness in its internal control over financial reporting that, if not remediated, could result in additional material misstatements in its consolidated financial statements.
Operational Risks
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.
Exploration and development drilling involve substantial costs and risks and may not result in commercially productive reserves.
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 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.
Multi-well pad drilling may result in volatility in the Company's operating results.
The Company's operations are substantially dependent upon the availability of water and its ability to dispose of produced water gathered from drilling and production activities.
The Company's use of seismic data is subject to interpretation and may not accurately identify the presence of oil and gas, which could materially and adversely affect the results of its drilling operations.

A failure by purchasers of the Company's production to satisfy their obligations to the Company could have a material adverse effect on the Company's results of operations.
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 Company's derivative risk management activities could result in financial losses, limit the Company’s potential gains or fail to protect the Company from declines in commodity prices.
Pioneer's ability to utilize its historic U.S. net operating loss carryforwards and those of Parsley may be limited.
The Company periodically evaluates its unproved oil and gas properties to determine recoverability of its cost and could be required to 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.
Health, Safety and Environmental Risks
The Company's operations are subject to a series of risks arising out of the threat of climate change.
The nature of the Company's assets and production operations may impact the environment or cause environmental contamination.
The Company's hydraulic fracturing and former sand mining operations may result in silica-related health issues and litigation.
Increasing attention to ESG matters may impact the Company’s business.
Regulatory Risks
The Company's operations are subject to stringent environmental, oil and gas-related and occupational safety and health legal requirements.
Laws, regulations and other executive actions or regulatory initiatives regarding hydraulic fracturing could increase the Company's cost of doing business and result in additional operating restrictions, delays or cancellations that could have a material adverse effect on the Company's business, results of operations and financial condition.
Laws and regulations pertaining to protection of threatened and endangered species or to critical habitat, wetlands and natural resources could delay, restrict or prohibit the Company's operations and cause it to incur substantial costs.
The Company's transportation of gas, sales and purchases of oil, NGLs and gas or other energy commodities, and any derivative activities related to such energy commodities, expose the Company to potential regulatory risks.
The enactment of derivatives legislation could have a material adverse effect on the Company's ability to use derivative instruments to reduce the effect of commodity price, interest rate and other risks.
The Company's bylaws provide that the Court of Chancery of the State of Delaware (or if the Court of Chancery does not have jurisdiction, the federal district court for the District of Delaware) will be the exclusive forum for certain legal actions between the Company and its stockholders and that the federal district courts of the United States shall be the sole and exclusive forum for the resolution of causes of action arising under the Securities Act of 1933.
Risks associated with the Parsley Acquisition
The financial and operational synergies attributable to the Parsley Acquisition may vary from expectations.
Litigation relating to the Parsley Acquisition could result in substantial costs to the Company.

General business and industry risks.
The COVID-19 pandemic and recent developments in the global oil markets have had, and may continue to have, material adverse consequences for general economic, business and industry conditions and for the Company's operations, financial condition, results of operations, cash flows and liquidity and those of its purchasers, suppliers and other counterparties.
The COVID-19 pandemic has significantly affected the global economy, disrupted global supply chains and created significant volatility in the financial markets. In addition, the pandemic has resulted in travel restrictions, business closures and other restrictions that have led to a significant reduction in demand for oil, NGL and gas, which, when combined with the oil supply increase attributable to the battle for market share among OPEC, Russia and other oil producing nations that occurred during the first quarter of 2020, resulted in oil prices declining significantly beginning in late February 2020. For instance, on April 20, 2020, WTI crude oil future prices for May reached a record low of negative $37.63 per barrel. As a result of the pandemic and low oil prices, the Company reduced its 2020 drilling, completion, facilities and water infrastructure capital budget significantly in an effort to fund its budget fully from its forecasted cash flow. While prices for oil, NGLs and gas have generally improved during the fourth quarter of 2020 and the first quarter of 2021, if the reduced demand for and prices of oil, NGLs and gas, or the oversupply of oil, were to continue for a prolonged period, the Company may have to make changes to its operations and capital budgets, and the Company's operations, financial condition, results of operations, cash flows and liquidity may be materially and adversely affected. Risks include, but are not limited to, the following:
An extended decline in commodity prices could materially and adversely affect the amount of oil, NGL and gas that the Company can produce economically, which may result in (i) the Company having to make significant downward adjustments to its estimated proved reserves and (ii) a shortfall in expected cash flows, which could require the Company to reduce capital spending or borrow funds to cover any such shortfall. In addition, the continuation of depressed prices may adversely affect the ability of the Company to pay dividends or repurchase shares of common stock in the future.
The reduced demand for oil, combined with the oversupply of oil, is expected to result in an oil surplus in the United States and worldwide. If the global demand for oil exports to foreign markets, or if the price that can be obtained in foreign markets does not support the transportation and other costs to reach those destinations, it may be uneconomical to invest in new wells and may cause the Company to shut in producing wells. The Company cannot be certain whether shut-in wells can successfully return to pre-shut-in production levels or that the costs required to return the wells to production will be economical.
The Company's ability to develop and sell its production could be materially and adversely affected by the inability or unwillingness of third parties to provide sufficient processing, fractionation, refining, transportation, storage or export facilities to the Company. For example, oil storage in the United States has, at times, been near full capacity in many locations. If this were to occur for an extended period, the Company's purchasers might decline to purchase the Company's oil, NGLs and gas, and the Company may not be able to store its production. Such a lack of market for or storage capacity for the Company's products could require that the Company shut in some portion of its production. The amount of oil in storage may also keep oil prices at low levels for an extended period, even after demand begins to rise.
Under Texas law, the Texas Railroad Commission is empowered to prorate oil production in the state based on market demand. If the Texas Railroad Commission finds that waste is taking place or is reasonably imminent, it is empowered to adopt a rule or order to correct, prevent, or lessen the waste. If the Texas Railroad Commission imposes proration in the future, or if any other similar laws or regulations are imposed, those restrictions would limit the amount of oil and gas the Company can produce.
It is possible that any delay, reduction or curtailment of the Company's development and producing operations, whether due to regulatory actions or actions by the Company in reaction to market conditions, could result in the loss of acreage through lease expiration.
Market conditions resulting from the effects of the COVID-19 pandemic, low oil prices, or a negative or recessionary economy could also increase the risk that the purchasers of the Company's production, lenders under its credit agreements, counterparties to its derivative instruments, and service providers may be unable to fulfill their obligations in a timely manner, or at all. If any such counterparty were to default on its obligations, such a default could have a material adverse effect on the Company's results of operations.
The Company performs assessments of its proved and unproved oil and gas properties whenever events or circumstances indicate that the carrying values of those assets 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 proved oil and gas properties, an impairment charge could be required to reduce the carrying value of its proved oil and gas properties to their fair value. In addition, goodwill is assessed for impairment whenever it is likely that events or circumstances indicate that the carrying value of a reporting unit exceeds its fair value.

PIONEER NATURAL RESOURCES COMPANY
The Company's operations may be adversely affected if significant portions of its workforce are unable to work effectively, including because of illness, quarantines, social distancing, government actions, or other restrictions in connection with the COVID-19 pandemic. The Company, as recommended by the CDC, has implemented workplace restrictions, including guidance for employees to work remotely for health and safety reasons, where possible. As some employees may have been or may in the future be placed in workplaces where exposure to COVID-19 is possible, the Company may be subject to risk of liability should such employees allege that the Company failed to adequately mitigate the risk of exposure to COVID-19, to the extent obligated to do so. In addition, in order to facilitate remote working arrangements, some employees are accessing workspaces from their personal devices through cloud-based systems, which could increase cybersecurity risks to the Company and to its employees. There can be no assurance that the Company's operations will not be curtailed or suspended or otherwise adversely affected due to such workforce issues.
The Company is not able to predict the ultimate long-term impact of the COVID-19 pandemic on the Company's business, which will depend on numerous evolving factors and future developments that are beyond the Company's control, including the length of time that the pandemic continues, the speed and effectiveness of responses to combat the virus, the impact of the pandemic and its aftermath on the demand for oil, NGLs and gas, the response of the overall economy and the financial markets as well as the effect of governmental actions taken in response to the COVID-19 pandemic.
Declining general economic, business or industry conditions could have a material adverse effect on the Company's results of operations.
The economies in the United States and certain countries in Europe and Asia have been growing, with resulting improvements in industrial demand and consumer confidence. However, other economies, such as those of certain South American nations, continue to face economic struggles or slowing economic growth. If these conditions worsen, combined with a decline in economic growth in other parts of the world, there could be a significant adverse effect on global financial markets and commodity prices. In addition, continued hostilities in the Middle East, and the occurrence or threat of terrorist attacks in the United States or other countries could adversely affect the global economy. Global or national health concerns, including the outbreak of pandemic or contagious disease, such as the COVID-19 pandemic, may adversely affect the Company by (i) reducing demand for its oil, NGL and gas because of reduced global or national economic activity, (ii) impairing its supply chain (for example, by limiting manufacturing of materials used in operations), and (iii) affecting the health of its workforce, rendering employees unable to work or travel. If the economic climate in the United States or abroad were to deteriorate, demand for petroleum products could diminish or stagnate, which could depress the prices at which the Company could sell its oil, NGLs and gas, affect the ability of the Company's vendors, suppliers and customers to continue operations and ultimately decrease the Company's cash flows and profitability. In addition, reduced worldwide demand for debt and equity securities issued by oil and gas companies may make it more difficult for it to raise capital.
The Company may be unable to make attractive acquisitions and any acquisition it completes is subject to substantial risks that could materially and adversely affect its business.
Acquisitions of oil and gas properties, including acreage trades, have from time to time contributed to the Company's growth. 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:
the inability to accurately forecast future commodity prices and estimate the costs to develop the acquired reserves, the recoverable volumes of the acquired reserves, rates of future production and future net cash flows attainable from the acquired reserves;
the assumption of unknown liabilities, including environmental liabilities, and 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 or from the amount of debt assumed as part of the acquisition;
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

15

PIONEER NATURAL RESOURCES COMPANY
benefits of the acquisition. See Risks Associated with the Parsley Acquisition included in "Item 1A. Risk Factor" for additional information.
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 its oil and gas properties 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 pre-closing matters, such as matters of litigation, environmental contingencies, royalty obligations and income taxes. 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 operations and drilling activity are concentrated in the Permian Basin of West Texas, an area 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; such concentration also makes the Company vulnerable to risks associated with operating in a limited geographic area.
The Company's producing properties are geographically concentrated in the Permian Basin of West Texas. Industry activity is high in the Permian Basin and demand for and costs of personnel, equipment, power, services and resources remains high. Any delay or inability to secure the personnel, equipment, power, services and resources could result in oil, NGL 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 results of operations, cash flow and profitability.
As a result of this concentration, the Company may be disproportionately exposed to the impact of delays or interruptions of operations or production in this area caused by external factors such as governmental regulation, state politics, market limitations, water or sand shortages or extreme weather related conditions.
The Company may not be able to obtain access on commercially reasonable terms or otherwise to pipelines and storage facilities, gathering systems and other transportation, processing, fractionation, refining and export 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, gathering systems and other transportation, processing, fractionation, refining and export 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 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 gather, store, process, transport, fractionate, refine, export and sell its oil, NGL and gas production. The Company's plans to develop and sell production from its oil and gas reserves could be materially and adversely affected by the inability or unwillingness of third parties to provide sufficient gathering, transportation, storage, processing, fractionation, refining or export facilities to the Company, especially in areas of planned expansion where such facilities do not currently exist. Additionally, certain of these challenges may be compounded by a high level of industry activity in the Permian Basin.
For example, following Hurricane Harvey in 2017 and Hurricanes Gustav and Ike in 2008, certain Permian Basin gas processors were forced to shut down their plants due to the inability of certain Texas Gulf Coast NGL fractionators to operate. 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 limitations in certain circumstances, such as pipeline interruptions due to scheduled and unscheduled maintenance, excessive pressure, physical damage to the gathering, transportation, storage, processing, fractionation, refining or

16

Table of Contents
PIONEER NATURAL RESOURCES COMPANY
export facilities, or lack of capacity at 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 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 related to pipeline transportation, reporting requirements, or other regulations, and any failure to comply with a FERC-related pipeline's tariff, could result in the imposition of civil and criminal penalties. In addition, any changes in FERC or state regulations or requirements on pipeline transportation may result in increased transportation costs on pipelines that are subject to such regulation, thereby negatively impacting the Company's profitability.
A limited number of companies purchase a majority of the Company's oil, NGL and gas. The loss of a significant purchaser could have a material adverse effect on the Company's ability to sell its production.
The refining industry may be unable to absorb U.S. oil production; in such a case, the resulting surplus could depress prices and restrict the availability of markets, which could materially and adversely affect the Company's results of operations.
Absent an expansion of U.S. refining and export capacity, an increase in U.S. production of oil could result in a surplus of these products in the U.S., which would likely cause prices for these commodities to fall and markets to constrict. Although U.S. law was changed in 2015 to permit the export of oil, exports may not occur if demand is lacking in foreign markets or the price that can be obtained in foreign markets does not support associated export capacity expansions, transportation and other costs. In such circumstances, the rate of return 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.
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 development costs, operating costs, severance, ad valorem and excise taxes, gathering, processing, transportation and fractionation 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 differ from the estimates, and the differences may be material.

17

Table of Contents
PIONEER NATURAL RESOURCES COMPANY
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;
the level of future capital spending;
increases or decreases in the supply of or demand for oil, NGL 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 historical 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 future 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 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.
Because the Company's producing wells decline continually over time, the Company will need to mitigate these declines through drilling and production enhancement initiatives and/or acquisitions.
Producing oil and gas reservoirs are characterized by declining production rates, which vary depending upon reservoir characteristics and other factors. Because the Company's producing wells decline continually over time as those wells are produced, the Company will need to mitigate these declines through drilling and production enhancement initiatives and/or acquisitions of additional recoverable reserves. There can be no assurance that the Company will be able to develop, exploit, find or acquire sufficient additional reserves to replace its current or future production.
A portion of the Company's total estimated proved reserves at December 31, 2020 were undeveloped, and those proved reserves may not ultimately be developed.
At December 31, 2020, approximately five percent of the Company's total estimated proved reserves were undeveloped. Recovery of undeveloped proved reserves requires significant capital expenditures and successful drilling. The Company's reserve data assumes that the Company can and will make these expenditures and conduct these operations successfully, which assumptions may not prove to be correct. If the Company chooses not to spend the capital to develop these proved undeveloped reserves, or if the Company is not otherwise able to successfully develop these proved undeveloped reserves, the Company will be required to write-off these proved reserves. In addition, under the SEC's rules, because proved undeveloped reserves may be booked only if they relate to wells planned to be drilled within five years of the date of booking, the Company may be required to write-off any proved undeveloped reserves that are not developed within this five-year timeframe. As with all oil and gas leases, the Company's leases require the Company to drill wells that are commercially productive and to maintain the production in paying quantities, and if the Company is unsuccessful in drilling such wells and maintaining such production, the Company could lose its rights under such leases. In addition, the Company's future production levels and, therefore, its future cash flow and profitability will be impacted if it is not able to successfully develop its undeveloped leasehold acreage.
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 exploration or development;
marketing oil, NGL and gas production; and
seeking to acquire the equipment, services and expertise, including trained personnel, necessary to identify, evaluate, develop and operate its properties.
Some of the Company's competitors are larger and have substantially greater financial and other resources than the Company, and as such, the Company may be at a competitive disadvantage in the identification, acquisition and development of properties that complement the Company's operations. The Company also faces competition from companies that supply alternative sources of energy, such as wind, solar power or other renewable energy. Competition is expected to increase and in

18

Table of Contents
PIONEER NATURAL RESOURCES COMPANY
certain cases, governments are providing tax advantages and other subsidies to support alternative energy sources or are mandating the use of specific fuels or technologies. Governments and other parties are also promoting research into new technologies to accelerate the implementation of alternative energy sources.
The Company's business could be materially and adversely 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, or control of, sensitive information or to render data or systems corrupted or 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. Costs for insurance may also increase as a result of security threats, and some insurance coverage may become more difficult to obtain, if available at all. 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 and cash flows.
Cybersecurity attacks in particular are becoming more sophisticated. The Company relies extensively on information technology systems, including internet sites, computer software, data hosting facilities and other hardware and platforms, some of which are hosted by third parties, to assist in conducting its business. The Company's technologies systems and networks, and those of its business associates may become the target of cybersecurity attacks, including without limitation denial-of-service attacks, malicious software, data privacy breaches by employees, insiders or others with authorized access, cyber or phishing-attacks, ransomware, attempts to gain unauthorized access to data and systems, and other electronic security breaches that could lead to disruptions in critical systems and materially and adversely affect the Company in a variety of ways, including the following:
unauthorized access to and release of seismic data, reserves information, strategic information or other sensitive or proprietary information, which could have a material adverse effect on the Company's ability to compete for oil and gas resources;
data corruption, communication interruption or other operational disruptions during drilling activities, which could result in the failure to reach the intended target or a drilling incident;
data corruption or operational disruptions of production infrastructure, which could result in loss of production or accidental discharges;
unauthorized access to and release of personal information of royalty owners, employees and vendors, or the data or confidential information of customers, suppliers or other third parties, which could expose the Company to allegations that it did not sufficiently protect that information;
a cybersecurity attack on a vendor or service provider, which could result in supply chain disruptions and could delay or halt operations;
a cybersecurity attack on third-party gathering, transportation, processing, fractionation, refining, storage or export facilities, which could delay or prevent the Company from transporting and marketing its production, resulting in a loss of revenues;
a cybersecurity attack involving commodities exchanges or financial institutions, which could slow or halt commodities trading, thus preventing the Company from marketing its production or engaging in derivative activities, resulting in a loss of revenues;
a cybersecurity attack on a communications network or power grid, which could cause operational disruptions resulting in the loss of revenues; and
a cybersecurity attack on the Company's automated and surveillance systems, which could cause a loss in production and potential environmental hazards.
These events could damage the Company's reputation and lead to financial losses from remedial actions, loss of business or potential liability. Additionally, certain cyber incidents, such as surveillance, may remain undetected for an extended period of time.
While the Company has experienced cybersecurity attacks in the past, including attempts to gain unauthorized access to data and systems, inadvertent data privacy breaches by employees and phishing-attacks, the Company has not suffered any material losses as a result of such attacks. However, there is no assurance that the Company will not suffer such losses in the future. As cyber threats continue to evolve, the Company may be required to expend significant additional resources to continue

to modify or enhance its protective measures or to investigate and remediate any information security vulnerabilities. Additionally, the continuing and evolving threat of cybersecurity attacks has resulted in evolving legal and compliance matters, including increased regulatory focus on prevention, which could require the Company to expend significant additional resources to meet such requirements.
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 transactions and thereby negatively affect the price that investors might be willing to pay in the future for the Company's common stock.

The Company has identified a material weakness in its internal control over financial reporting that, if not remediated, could result in additional material misstatements in its consolidated financial statements.

As described in "Part II, Item 9A — Controls and Procedures," management has identified and evaluated the control deficiencies that gave rise to the accounting corrections related to contracts governing the sale of purchased oil and gas and has concluded that those deficiencies, collectively, represent a material weakness in the Company's internal control over financial reporting. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the Company's annual or interim financial statements will not be prevented or detected on a timely basis. As a result of the material weakness, management has concluded that the Company did not maintain effective internal control over financial reporting as of December 31, 2020. See Note 2 of Notes to Consolidated Financial Statements and "Unaudited Supplementary Information - Selected Quarterly Financial Results" included in "Item 8. Financial Statements and Supplementary Data" for additional information.

The Company is in the process of developing and implementing a remediation plan to address the material weakness. If the Company’s remediation efforts are insufficient or if additional material weaknesses in its internal control over financial reporting are discovered or occur in the future, the Company's consolidated financial statements may contain material misstatements and it could be required to revise or restate its financial results, which could materially and adversely affect the Company’s business, results of operations and financial condition, restrict its ability to access the capital markets, require it to expend significant resources to correct the material weakness, subject it to fines, penalties or judgments, harm its reputation or otherwise cause a decline in investor confidence.
Operational risks.
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 drilling and completion activities and water distribution, collection and disposal activities, are subject to all the risks incident to the oil and gas development and production business, including:
blowouts, cratering, explosions and fires;
adverse weather effects;
environmental hazards, such as NGL and gas leaks, oil and produced water spills, pipeline and vessel ruptures, encountering naturally occurring radioactive materials ("NORM"), and unauthorized discharges of toxic chemicals, gases, brine, well stimulation and completion fluids or other pollutants onto the surface or into the subsurface environment;
high costs, shortages or delivery delays of equipment, labor or other services or materials, such as water and sand for hydraulic fracturing;
facility or equipment malfunctions, failures or accidents;
title problems;
pipe or cement failures or casing collapses;
uncontrollable flows of oil, gas or water;
compliance with environmental and other governmental requirements, including executive actions and regulatory or legislative efforts under a Biden administration;
lost or damaged oilfield workover and service tools;
surface access restrictions;
unusual or unexpected geological formations or pressure or irregularities in formations;

20

Table of Contents
PIONEER NATURAL RESOURCES COMPANY
terrorism, vandalism and physical, electronic and cybersecurity breaches and global or national health concerns, including the outbreak of a pandemic or contagious disease, such as the recent COVID-19 pandemic; and
natural disasters.
The Company's overall exposure to operational risks may increase as its drilling activity expands, along with any associated increases in internally-provided well services, water distribution, water collection, disposal or other services. In addition, any of these risks could adversely impact the Company's service providers and suppliers, causing its supply chain to be interrupted, slowed or rendered inoperable. 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 and natural resources, clean-up responsibilities, regulatory investigations and penalties and suspension of operations.
The Company may not be insured or 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 adversely affect the ability of the Company to gather, produce, transport, process, fractionate, refine, store, export and sell its hydrocarbons.
Exploration and development drilling involve substantial costs and risks and 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;
unexpected pressure or irregularities in formations;
equipment failures or accidents;
construction delays;
fracture stimulation accidents or failures;
adverse weather conditions;
restricted access to land for drilling or laying pipelines;
title defects;
lack of available gathering, transportation, processing, fractionation, storage, refining or export facilities;
lack of available capacity on interconnecting transmission pipelines;
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; and
delays imposed by or resulting from compliance with or changes in environmental and other governmental, regulatory or contractual requirements.
The Company's future drilling activities may not be successful and, if unsuccessful, the Company's proved reserves and production would decline, which 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 recognize exploration and abandonment expense in 2021.
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.

Drilling in emerging areas is more uncertain than drilling in areas that are more developed and have a longer history of established drilling operations. 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 charges to reduce the carrying value of its unproved properties in those areas.
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, extension 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, 2020 include proved undeveloped reserves and proved developed non-producing reserves of 31 MMBbls of oil, 17 MMBbls of NGL and 88 Bcf of gas. The Company's ability to drill and develop these locations depends on a number of factors, including the availability and cost of capital, regulatory approvals, negotiation of agreements with third parties, commodity prices, costs, access to and availability of equipment, services, resources and personnel, and drilling results. There can be no assurance that the Company will drill these locations or that the Company will be able to produce oil or gas reserves from these locations or any other potential drilling locations. Well results vary by formation and geographic area, and the Company generally prioritizes its drilling activities to focus on remaining locations that are believed to offer the highest return. Changes in the laws or regulations on which the Company relies in planning and executing its drilling programs could materially and 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 materially and 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 material adverse effect on the Company's proved reserves, financial condition and results of operations.
Multi-well pad drilling may result in volatility in the Company's operating results.
The Company utilizes multi-well pad drilling, and wells drilled on a pad are not placed on production until all wells on the pad are drilled and completed. In addition, problems affecting a single well could adversely affect production from all of the wells on the pad. As a result, multi-well pad drilling can cause delays in the scheduled commencement of production, or interruptions in ongoing production. These delays or interruptions may cause volatility in the Company's operating results. Further, any delay, reduction or curtailment of the Company's development and producing operations due to operational delays caused by multi-well pad drilling could result in the loss of acreage through lease expiration.
The Company's operations are substantially dependent upon the availability of water and its ability to dispose of produced water gathered from drilling and production activities. Restrictions on the Company's ability to obtain water or dispose of produced water may have a material adverse effect on its financial condition, results of operations and cash flows.
Water is an essential component of the Company's drilling and hydraulic fracturing processes. Limitations or restrictions on the Company's ability to secure sufficient amounts of water (including limitations resulting from natural causes such as drought), could materially and adversely impact its operations. Severe drought conditions can result in local water districts taking steps to restrict the use of water in their jurisdiction for drilling and hydraulic fracturing in order to protect the local water supply. If the Company is unable to obtain water to use in its operations from local sources, it may need to be obtained from new sources and transported to drilling sites, resulting in increased costs, which could have a material adverse effect on its financial condition, results of operations and cash flows.
In addition, the Company must dispose of the fluids produced from oil and gas production operations, including produced water, which it does directly or through the use of third party vendors. The legal requirements related to the disposal of produced water into a non-producing geologic formation by means of underground injection wells are subject to change based on concerns of the public or governmental authorities regarding such disposal activities. One such concern arises from seismic events near underground disposal wells that are used for the disposal of produced water resulting from oil and gas activities. In 2016, the United States Geological Survey identified Texas as being among the states with areas of increased rates of induced seismicity that could be attributed to fluid injection or oil and gas extraction. While the agency has seen these rates decrease since that time, concern continues to exist over earthquakes arising from induced seismic activities. In response to concerns regarding induced seismicity, regulators in some states have imposed, or are considering imposing, additional requirements in the permitting of produced water disposal wells to assess any relationship between seismicity and the use of such wells. For example, in Texas, the Texas Railroad Commission has adopted rules governing the permitting or re-permitting

22

Table of Contents
PIONEER NATURAL RESOURCES COMPANY
of wells used to dispose of produced water and other fluids resulting from the production of oil and gas in order to address these seismic activity concerns within the state. Among other things, these rules require companies seeking permits for disposal wells to provide seismic activity data in permit applications, provide for more frequent monitoring and reporting for certain wells and allow the state to modify, suspend or terminate permits on grounds that a disposal well is likely to be, or determined to be, causing seismic activity.
States may issue orders to temporarily shut down or to curtail the injection depth of existing wells in the vicinity of seismic events. Another consequence of seismic events may be lawsuits alleging that disposal well operations have caused damage to neighboring properties or otherwise violated state and federal rules regulating waste disposal. These developments could result in additional regulation and restrictions on the use of injection wells by the Company or by commercial disposal well vendors whom the Company may use from time to time to dispose of produced water. Increased regulation and attention given to induced seismicity could also lead to greater opposition, including litigation to limit or prohibit oil and gas activities utilizing injection wells for produced water disposal. Any one or more of these developments may result in the Company or its vendors having to limit disposal well volumes, disposal rates and pressures or locations, or require the Company or its vendors to shut down or curtail the injection of produced water into disposal wells, which events could have a material adverse effect on the Company's business, financial condition and results of operations.
The Company's use of seismic data is subject to interpretation and may not accurately identify the presence of oil and gas, which could materially and adversely affect the results of its drilling operations.
Even when properly used and interpreted, seismic data and visualization techniques are only tools used to assist geoscientists in identifying subsurface structures and hydrocarbon indicators and do not enable the interpreter to know whether hydrocarbons are, in fact, present in those structures. As a result, the Company's drilling activities may not be successful or economic. In addition, the use of advanced technologies, such as 3-D seismic data, requires greater pre-drilling expenditures than traditional drilling strategies, and the Company could incur losses as a result of such expenditures.
The Company's gas processing, gathering and treating operations are subject to operational and regulatory risks, which could result in significant damages and the loss of revenue.
As of December 31, 2020, the Company owns interests in 11 gas processing plants, including the related gathering systems. There are significant risks associated with the operation of gas processing plants and the associated gathering systems. Gas and NGLs are volatile and explosive and may include carcinogens. Damage to or improper operation of gas processing plants, gathering systems or treating facilities 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.
Moreover, while the Company's gas processing and gathering systems generally are not currently subject to FERC or state regulation with respect to rates or terms and conditions of service, there can be no assurance that such processing and gathering operations will continue to be unregulated in the future. Although these facilities may not be directly regulated, other laws and regulations may affect the availability of gas for gathering and processing, such as state regulations regarding production rates and the maximum daily production allowable from gas wells, which could impact the Company's business in these areas. Such regulation could result in additional costs and reduced revenues.
Financial risks.
The prices of oil, NGL and gas are highly volatile. A sustained decline in these commodity prices could materially and adversely affect the Company's business, 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;
worldwide oil, NGL and gas inventory levels, including at Cushing, Oklahoma, the benchmark location for WTI oil prices, and the U.S. Gulf Coast, where the majority of the U.S. refinery capacity exists;
volatility and trading patterns in the commodity-futures markets;
the capacity of U.S. and international refiners to utilize U.S. supplies of oil and condensate;
weather conditions;
overall domestic and global political and economic conditions, including the imposition of tariffs or trade or other economic sanctions, political instability or armed conflict in oil and gas producing regions;

23

Table of Contents
PIONEER NATURAL RESOURCES COMPANY
global or national health concerns, including the outbreak of pandemic or contagious disease, such as the recent coronavirus, which may reduce the demand for oil, NGL and gas because of reduced global or national economic activity;
actions of OPEC, its members and other state-controlled oil companies relating to oil price and production controls;
the price and quantity of oil, NGL and LNG imports to and exports from the U.S.;
technological advances or social attitudes or policies affecting energy consumption and energy supply;
domestic and foreign governmental legislative efforts, executive actions and regulations, including environmental regulations, climate change regulations and taxation;
the effect of energy conservation efforts;
stockholder activism or activities by non-governmental organizations to limit certain sources of capital for the energy sector or restrict the exploration, development and production of oil and gas;
the proximity, capacity, cost and availability of pipelines and other processing, fractionation, refinery, storage and export facilities; and
the price, availability and acceptance of alternative fuels.
Commodity prices have historically been, and continue to be, extremely volatile. For example, the Brent oil prices in 2020 ranged from a high of $68.91 to a low of $19.33 per Bbl and the NYMEX gas prices in 2020 ranged from a high of $3.35 to a low of $1.48 per MMBtu. The Company expects this volatility to continue. A further or extended decline in commodity prices could materially and adversely affect the Company's future business, financial condition, results of operations, liquidity or its ability to fund planned capital expenditures, pay dividends or repurchase shares of common stock. 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 noncancellable capital and transportation 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 materially and adversely affect the amount of oil, NGL and gas that the Company can produce economically, which may result in the Company having to make significant downward adjustments to its estimated proved reserves. A reduction in production could also 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.
Future declines in the price of oil, NGLs and gas could result in a reduction in the carrying value of the Company's proved oil and gas properties, which could materially and adversely affect the Company's results of operations.
Significant or extended price declines could result in the Company having to make downward adjustments to the carrying value of its proved oil and gas properties. The Company performs assessments of the recoverability of its 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) proved reserves and risk-adjusted probable and possible reserves, (ii) commodity prices, (iii) production costs, (iv) capital expenditures and (v) production. 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 2018, the Company recorded impairment charges of $77 million attributable to its Raton Basin field in southeast Colorado, primarily due to declines in commodity prices and downward adjustments to the economically recoverable reserves attributable to the asset. The Company may incur impairment charges in the future, which could materially affect the Company's results of operations in the period incurred. See "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Results of Operations - Impairment of oil and gas properties and other long-lived assets" and Note 4 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.
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 and other financial and operating results. These forecasts are based on a number of estimates and assumptions, including that none of the risks associated with the Company's oil and gas operations summarized in this "Item 1A. Risk Factors" occur. Production forecasts, specifically, are based on assumptions such as:
expectations of production from existing wells and future drilling activity;
the absence of facility or equipment malfunctions;
the absence of adverse weather effects;

24

Table of Contents
PIONEER NATURAL RESOURCES COMPANY
expectations of commodity prices, which could experience significant volatility;
expected well costs; and
the assumed effects of regulation by governmental agencies, which could make certain drilling activities or production uneconomical.
Should any of these assumptions prove inaccurate, or should the Company's development plans change, actual production could be materially and adversely affected.
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 production and ad valorem taxes. Decreased levels of drilling activity in the oil and gas industry have historically led to cost reductions for some drilling equipment, materials and supplies. However, such costs may rise faster than increases in the Company's revenue if commodity prices rise, 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 is a party to debt instruments, a credit facility and other financial commitments that may limit the Company's ability to fund future business and financing activities.
The Company is a borrower under fixed rate senior and convertible notes and maintains a credit facility that was undrawn as of December 31, 2020. 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. In addition, from time to time, the Company enters into arrangements and transactions that can give rise to material off-balance sheet obligations, including firm purchase, transportation and fractionation commitments, gathering, processing, transportation and storage commitments on uncertain volumes of future throughput, commitments to purchase minimum volumes of goods and services, operating lease agreements and drilling commitments. The Company's financial commitments could have important consequences to its business including, but not limited to, the following:
the incurrence of charges associated with unused commitments if actual activities do not meet the Company's expectations at the time such commitments are entered into;
increasing its vulnerability to adverse economic and industry conditions;
limiting its flexibility to plan for, or react to, changes in its business and industry;
limiting its ability to fund future development activities or engage in future acquisitions; and
placing it at a competitive disadvantage compared to competitors that have less debt and/or fewer financial commitments.
The Company's ability to obtain additional financing is also affected by the Company's debt credit ratings and competition for available debt financing. A ratings downgrade could materially and adversely impact the Company's ability to access debt markets, increase the borrowing cost under the Company's credit facility and the cost of future debt and potentially require the Company to post letters of credit or other forms of credit support for certain obligations.
The Company's ability to declare and pay dividends and repurchase shares is subject to certain considerations.
Dividends are authorized and determined by the Company's board of directors in its sole discretion. The Company's stock repurchase program has no time limit, may be modified, suspended or terminated at any time by the board of directors, and the repurchase of shares pursuant to the stock repurchase program approved by the board of directors are made from time to time based on management's discretion. Decisions regarding the payment of dividends and the repurchase of shares are subject to a number of considerations, including:
cash available for distribution or repurchases;
the Company's results of operations and anticipated future results of operations;
the Company's financial condition, especially in relation to the anticipated future capital needs;
the level of cash reserves the Company may establish to fund future capital expenditures;
the Company's stock price; and

25

Table of Contents
PIONEER NATURAL RESOURCES COMPANY
other factors the board of directors deems relevant.
The Company can provide no assurance that it will continue to pay dividends or authorize share repurchases at the current rate or at all. Any elimination of or downward revision in the Company's dividend payout or stock repurchase program could have a material adverse effect on the market price of the Company's common stock.
A failure by purchasers of the Company's production to satisfy their obligations to the Company could 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 charge in the earnings of that period for the probable loss.
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. The Company is unable to predict changes in a counterparty's creditworthiness or ability to perform. Even if the Company accurately predicts sudden changes, the Company's ability to negate the risk may be limited depending upon market conditions and the contractual terms of the transactions. During periods of declining commodity prices, the Company's derivative receivable positions generally increase, which increases the Company's counterparty credit exposure. If any of the Company's counterparties were to default on its obligations under the Company's derivative arrangements, such a default could (i) have a material adverse effect on the Company's results of operations, (ii) result in a larger percentage of the Company's future production being subject to commodity price changes and (iii) increase the likelihood that the Company's derivative arrangements may not achieve their intended strategic purposes.
The Company's derivative risk management activities could result in financial losses, limit the Company's potential gains or fail to protect the Company from declines in commodity prices; the Company may not enter into derivative arrangements with respect to future volumes if prices are unattractive.
The Company's strategy is to enter into derivative arrangements covering a portion of its oil, NGL and gas production to mitigate the effect of commodity price volatility on the Company's net cash provided by operating activities and its net asset value, support the Company's annual capital expenditure plans and planned dividend payments. In addition, Pioneer assumed existing derivative arrangements in the Parsley Acquisition, and they are now part of the Company's consolidated derivative arrangements. These derivative arrangements, on a combined basis, are subject to mark-to-market 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.
While intended to reduce the effects of oil, NGL and gas price volatility, the Company's derivative arrangements may limit the Company's potential gains if prices rise over the price established by such arrangements. Conversely, the Company's derivative arrangements may be inadequate to protect the Company from continuing and prolonged declines in the price of oil, NGL or gas. Global commodity prices are volatile. Such volatility challenges the Company's ability to forecast the price of oil, NGL and gas, and, as a result, it may become more difficult for the Company to manage its derivative arrangements. In trying to manage its exposure to commodity price risk, the Company may end up with too many or too few derivatives, depending upon where commodity prices settle relative to the Company's derivative price thresholds and how the Company's oil, NGL and gas volumes and production mix fluctuate relative to expectations when the derivatives were entered.
The Company's derivative arrangements may also expose the Company to risk of financial loss in certain circumstances, including, but not limited to, when:
production is less than the contracted derivative volumes;
the counterparty to the derivative contract defaults on its contract obligations;
there is a change in the expected differential between the underlying price in the derivative contract and actual prices received; or
a sudden, unexpected event materially impacts oil and gas prices.
Failure to protect against declines in commodity prices exposes the Company to reduced liquidity when prices decline. A sustained lower commodity price environment would result in lower realized prices for unprotected volumes and reduce the

26

Table of Contents
PIONEER NATURAL RESOURCES COMPANY
prices at which the Company could enter into derivative contracts on future volumes. This could make such transactions unattractive, and, as a result, some or all of the Company's production volumes forecasted for 2021 and beyond may not be protected by derivative arrangements. In addition, the Company's derivatives arrangements may not achieve their intended strategic purposes.
Pioneer's ability to utilize its historic U.S. net operating loss carryforwards and those of Parsley may be limited.
As of December 31, 2020, Pioneer and Parsley had U.S. federal net operating loss carryforwards ("NOLs") of $5.3 billion and $1.2 billion, respectively. Pioneer and Parsley NOLs of $2.8 billion and $611 million, respectively, were incurred prior to January 1, 2018 and will begin to expire, if unused, in 2032 and 2034, respectively, and $2.5 billion and $638 million, respectively, were incurred on or after January 1, 2018 and will not expire and will be carried forward indefinitely. Pioneer's ability to utilize these NOLs and other tax attributes to reduce future taxable income depends on many factors, including its future income, which cannot be assured. Section 382 of the Code ("Section 382") generally imposes an annual limitation on the amount of NOLs that may be used to offset taxable income when a corporation has undergone an "ownership change" (as determined under Section 382). An ownership change generally occurs if one or more stockholders (or groups of stockholders) who are each deemed to own at least five percent of such corporation's stock increase their ownership by more than 50 percentage points over their lowest ownership percentage within a rolling three-year period. In the event that an ownership change occurs, utilization of the relevant corporation's NOLs would be subject to an annual limitation under Section 382, generally determined, subject to certain adjustments, by multiplying (i) the fair market value of such corporation's stock at the time of the ownership change by (ii) a percentage approximately equivalent to the yield on long-term tax-exempt bonds during the month in which the ownership change occurs. Any unused annual limitation may be carried over to later years.
Parsley underwent an ownership change under Section 382 as a result of the Parsley Acquisition, which, based on information currently available, may trigger a limitation (calculated as described above) on Pioneer's ability to utilize any historic Parsley NOLs and could cause some of Parsley's NOLs incurred prior to January 1, 2018 to expire before Pioneer would be able to utilize them to reduce taxable income in future periods. While Pioneer's issuance of stock in the mergers would, standing alone, be insufficient to result in an ownership change with respect to Pioneer, the Company cannot assure that Pioneer will not undergo an ownership change as a result of the mergers taking into account other changes in ownership of Pioneer stock occurring within the relevant three-year period described above. If Pioneer were to undergo an ownership change, it may be prevented from fully utilizing its historic NOLs incurred prior to January 1, 2018.
The Company periodically evaluates its unproved oil and gas properties to determine recoverability of its cost and could be required to recognize noncash charges in the earnings of future periods.
At December 31, 2020, the Company carried unproved oil and gas property costs of $576 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 the 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 in the period in which the unproved oil and gas properties is determined to be impaired.
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, 2020, the Company had a carrying value for goodwill of $261 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 (i) positive or negative reserve adjustments, (ii) results of drilling activities, (iii) management's outlook for commodity prices and costs and expenses, (iv) changes in the Company's market capitalization, (v) changes in the Company's weighted average cost of capital and (vi) 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. If incurred, an impairment of the goodwill could result in a material noncash charge to the Company's earnings in the period in which goodwill is determined to be impaired.

Health, safety and environmental risks.
The Company's operations are subject to a series of risks arising out of the threat of climate change that could result in increased operating costs, limit the areas in which oil and gas production may occur, and reduce demand for the oil and gas production it provides.
The threat of climate change continues to attract considerable attention in the United States and around the world. Numerous proposals have been made and could continue to be made at the international, national, regional and state levels of government to monitor and limit existing emissions of GHGs as well as to restrict or eliminate such future emissions.
No comprehensive climate change legislation has been implemented at the federal level, but President Biden may pursue new climate change legislation and has already issued executive orders and may issue more orders or other regulatory initiatives to limit GHG emissions. At the federal level, the EPA has adopted rules that, among other things, establish construction and operating permit reviews for GHG emissions from certain large stationary sources, require the monitoring and annual reporting of GHG emissions from certain petroleum and gas system sources, and impose new standards reducing methane emissions from oil and gas operations through limitations on venting and flaring and the implementation of enhanced emission leak detection and repair requirements. In recent years, there has been considerable uncertainty surrounding regulation of methane emissions, as the EPA under the Obama Administration published a CAA final rule in 2016 establishing new source performance standards ("NSPS") for methane, but since that time the EPA has undertaken several measures, including publishing in September 2020 final rule policy and technical amendments to the NSPS, for stationary sources of air emissions. The policy amendments, effective September 14, 2020, notably removed the transmission and storage sector from the regulated source category and rescinded methane and volatile organic compound ("VOC") requirements for the remaining sources that were established by former President Obama's Administration, whereas the technical amendments, effective November 16, 2020, included changes to fugitive emissions monitoring and repair schedules for gathering and boosting compressor stations and low-production wells, recordkeeping and reporting requirements, and more. Various state, industry and environmental groups are separately challenging both the original 2016 standards and the EPA's September 2020 final rules and on January 20, 2021, President Biden issued an executive order, that among other things, directed EPA to reconsider the technical amendments and to issue a proposed rule suspending, revising or rescinding those amendments by no later than September 2021. A reconsideration of the September 2020 policy amendments is expected to follow. The January 20, 2021 executive order also directed the establishment of new methane and VOC standards applicable to existing oil and gas operations, including the production, transmission, processing and storage segments.
Additionally, various states and groups of states have adopted or are considering adopting legislation, regulations or other regulatory initiatives that are focused on such areas as greenhouse gas cap and trade programs, carbon taxes, reporting and tracking programs, and restriction of emissions. At the international level, President Biden issued executive orders in January 2021 re-committing the United States to the "Paris Agreement," a non-binding agreement for nations to limit their GHG emissions through individually-determined reduction goals every five years after 2020, and directed the federal government to formulate the United States' emissions reduction goal under the agreement. Separately, on January 27, 2021, President Biden issued an executive order that commits to substantial action on climate change, calling for, among other things, the increased use of zero emissions vehicles by the federal government, the elimination of subsidies provided to the fossil fuel industry and an increased emphasis on climate-related risks across government agencies and economic sectors.
Litigation risks are also increasing, as a number of states, municipalities and other plaintiffs have sought to bring suit against the largest oil and gas exploration and production companies in state or federal court, alleging, among other things, that such energy companies created public nuisances by producing fuels that contributed to global warming effects, such as rising sea levels, and therefore, are responsible for roadway and infrastructure damages as a result, or alleging that the companies have been aware of the adverse effects of climate change for some time but defrauded their investors by failing to adequately disclose those impacts. There are also increasing financial risks for fossil fuel producers and other companies supportive of the oil and gas industry as shareholders and bondholders currently invested in fossil-fuel energy companies concerned about the potential effects of climate change may elect in the future to shift some or all of their investments into non-fossil fuel energy related sectors. Institutional lenders who provide financing to fossil-fuel energy companies also have become more attentive to sustainable lending and investment practices and some of them may elect not to provide funding for fossil fuel energy companies. Additionally, there is the possibility that financial institutions will be required to adopt policies that limit funding for fossil fuel energy companies, as President Biden recently signed an executive order calling for the development of a climate finance plan and, separately, the Federal Reserve announced that it has joined the Network for Greening the Financial System, a consortium of financial regulators focused on addressing climate-related risks in the financial sector.
Finally, increasing concentrations of GHG in the Earth's atmosphere may produce climate changes that have significant physical effects, such as increased frequency and severity of storms, droughts, floods, rising sea levels and other climatic events. The occurrence of any one or more of these developments with respect to climate change initiatives and further

restrictions on GHG emissions could have a material adverse effect on the Company's business, financial condition and results of operations.
The nature of the Company's assets and production operations may impact the environment or cause environmental contamination, which could result in material liabilities to the Company.
The Company's assets and production operations may give rise to significant environmental costs and liabilities as a result of the Company's handling of petroleum hydrocarbons and wastes, because of air emissions and water discharges related to its operations, and due to past industry operations and waste disposal practices. The Company's oil and gas business involves the generation, handling, treatment, storage, transport and disposal of wastes, hazardous substances and petroleum hydrocarbons and is subject to environmental hazards, such as oil and produced water spills, NGL and gas leaks, pipeline and vessel ruptures and unauthorized discharges of such wastes, substances and hydrocarbons, that could expose the Company to substantial liability due to pollution and other environmental damage.
In recent years, wells used for the disposal by injection of flowback water or certain other oilfield fluids into non-producing formations have been associated with an increased number of seismic events, with research suggesting that the link between seismic events and wastewater disposal may vary by region and local geology. The U.S. geological survey has in the recent past identified six states with the most significant hazards from induced seismicity, which list included Texas. In response to these concerns, regulators in some states have adopted additional requirements related to seismicity and its potential association with hydraulic fracturing. For example, Texas has issued rules for wastewater disposal wells that imposed certain permitting and operating restrictions and reporting requirements on disposal wells in proximity to faults. Other states, such as Oklahoma, have also issued orders for certain wells where seismic incidents have occurred to restrict or suspend disposal well operations. Another consequence of seismic events may be lawsuits alleging that disposal well operations have caused damage to neighboring properties or otherwise violated state and federal rules regulating waste disposal. The occurrence of any one or more of these developments could have a material adverse effect on the Company's business, financial condition and results of operations.
The Company's hydraulic fracturing and former sand mining operations may result in silica-related health issues and litigation that could have a material adverse effect on the Company.
The Company routinely conducts hydraulic fracturing in its drilling and completion programs, which activity requires management and use of significant volumes of sand. Additionally, the Company owns and formerly operated certain sand mining operations. 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 personal injury lawsuits, recently adopted OSHA silica regulations and increased scrutiny by federal, state and local regulatory authorities. The occurrence of significant silica-related health issues as well as any pending or future claims or inadequacies of insurance coverage or contractual indemnification arising out of such issues could have a material adverse effect on the Company's results of operations.
Increasing attention to ESG matters may impact the Company's business.
Businesses across all industries are facing increasing scrutiny from stakeholders related to their ESG practices. Businesses that do not adapt to or comply with investor or stakeholder expectations and standards, which are evolving, or which are perceived to have not responded appropriately to the growing concern for ESG issues, regardless of whether there is a legal requirement to do so, may suffer from reputational damage and the business, financial condition, and/or stock price of such business entity could be materially and adversely affected. Increasing attention to climate change, increasing societal expectations on businesses to address climate change, and potential consumer use of substitutes to energy commodities may result in increased costs, reduced demand for the Company's hydrocarbon products, reduced profits, increased investigations and litigation, and negative impacts on its stock price and access to capital markets. Increasing attention to climate change, for example, may result in demand shifts for the Company's hydrocarbon products and additional governmental investigations and private litigation.
In addition, organizations that provide information to investors on corporate governance and related matters have developed ratings processes for evaluating business entities on their approach to ESG matters. Currently, there are no universal standards for such scores or ratings, but the importance of sustainability evaluations is becoming more broadly accepted by investors and shareholders. Such ratings are used by some investors to inform their investment and voting decisions. Additionally, certain investors use these scores to benchmark businesses against their peers and if a business entity is perceived as lagging, these investors may engage with such entities to require improved ESG disclosure or performance. Moreover,

29

Table of Contents
PIONEER NATURAL RESOURCES COMPANY
certain members of the broader investment community may consider a business entity's sustainability score as a reputational or other factor in making an investment decision. Consequently, a low sustainability score could result in exclusion of the Company's stock from consideration by certain investment funds, engagement by investors seeking to improve such scores and a negative perception of the Company's operations by certain investors.
Regulatory risks.
The Company's operations are subject to stringent environmental, oil and gas-related and occupational safety and health legal requirements that could increase its costs of doing business and result in additional operating restrictions, delays or cancellations in the completion of oil and gas wells, which could have a material adverse effect on the Company's business, results of operations and financial condition.
The Company's crude oil and gas exploration and production operations are subject to stringent federal, state and local legal requirements governing among other things, the drilling of wells, rates of production, the size and shape of drilling and spacing units or proration units, the transportation and sale of oil, NGLs and gas, the discharging of materials into the environment, environmental protection and occupational safety and health. These requirements may take the form of laws, regulations, and executive actions, and noncompliance with these legal requirements may subject the Company to sanctions, including administration, civil or criminal penalties, remedial cleanups or corrective actions, delays in permitting or performance of projects, natural resource damages and other liabilities.
In connection with its operations, the Company must obtain and maintain numerous environmental and oil and gas related permits, approvals and certificates from various federal, state and local governmental authorities, and may incur substantial costs in doing so. The need to obtain permits has the potential to delay, curtail or cease the development of oil and gas projects. The Company may in the future be charged royalties on gas emissions or required to incur certain capital expenditures for air pollution control equipment or other air emissions-related issues. For example, in 2015, the EPA under the Obama Administration issued a final rule under the CAA, making the National Ambient Air Quality Standard ("NAAQS") for ground-level ozone more stringent. Since that time, the EPA has issued area designations with respect to ground-level ozone and, more recently, in December 2020, the EPA, under the Trump Administration, published a final action that, upon conducting a periodic review of the ozone standard in accord with CAA requirements, elected to retain the 2015 ozone NAAQS without revision on a going-forward basis; however, several groups have filed litigation over this December decision, and the NAAQS may be subject to further revision under the Biden Administration. State implementation of the revised NAAQS could, among other things, require installation of new emission controls on some of the Company's equipment, result in longer permitting timelines, and significantly increase the Company's capital expenditures and operating costs.
In another example, in 2015, the EPA and U.S. Army Corps of Engineers ("Corps") under the Obama Administration released a final rule outlining federal jurisdictional reach under the CWA over waters of the United States; including wetlands; however, the 2015 rule was repealed by the EPA and the Corps under the Trump Administration in a final rule that became effective in December 2019. The EPA and the Corps also published a final rule in April 2020 re-defining the term "waters of the United States" as applied under the CWA and narrowed the scope of waters subject to federal regulation. The April 2020 final rule is subject to various pending legal challenges, and there is an expectation that this final rule will be reconsidered by the Biden Administration. If the EPA and the Corps revise the June 2020 final rule in a manner similar to or more stringent than the original 2015 final rule, or if any challenge to the June 2020 final rule is successful, the scope of the Clean Water Act's jurisdiction in areas where the Company conducts operations could again be expanded, which could result in increased costs and delay, restrict or halt permitting or development of projects.
Additionally, the Company's operations are subject to federal and state laws and regulations, including the federal OSHA and comparable state statutes, whose purpose is to protect the health and safety of employees. Among other things, the OSHA hazard communication standard, the EPA community right-to-know regulations under Title III of the federal Superfund Amendment and Reauthorization Act, and comparable state statutes require that information be maintained concerning hazardous materials used or produced in the Company's operations and that this information be provided to employees, state and local government authorities and citizens.
Compliance with these legal requirements, or any other new environmental or occupational safety and health laws, regulations or executive actions could, among other things, require the Company to install new or modified emission or safety controls on equipment or processes, incur longer permitting timelines, and incur increased capital or operating expenditures, which costs may be significant. Additionally, one or more of these developments could impact the Company's oil and gas exploration, production and development activities, which could have a material adverse effect on its business, results of operations and financial condition.

Laws, regulations and other executive actions or regulatory initiatives regarding hydraulic fracturing could increase the Company's cost of doing business and result in additional operating restrictions, delays or cancellations that could have a material adverse effect on the Company's business, results of operations and financial condition.
The Company routinely conducts hydraulic fracturing in its drilling and completion programs. Hydraulic fracturing is typically regulated by state oil and gas commissions, but the practice continues to attract considerable public, scientific and governmental attention in certain parts of the country, resulting in increased scrutiny and regulation, including by federal agencies.
At the federal level, the EPA asserted federal regulatory authority under the SDWA over certain hydraulic fracturing activities involving the use of diesel fuels and published permitting guidance for such activities. Additionally, the EPA issued a final regulation under the CWA prohibiting discharges to publicly owned treatment works of wastewater from onshore unconventional oil and gas extraction facilities. In late 2016, the EPA released its final report on the potential impacts of hydraulic fracturing on drinking water resources, concluding that "water cycle" activities associated with hydraulic fracturing may impact drinking water resources under certain circumstances. Also, in 2016, the BLM under the Obama Administration published a final rule imposing more stringent standards on hydraulic fracturing on federal lands; however, in late 2018, the BLM under the Trump Administration published a final rule rescinding the 2016 final rule. Since that time, litigation challenging the BLM's 2016 final rule and the 2018 final rule has resulted in rescission in federal courts of both the 2016 rule and the 2018 final rule but appeals of one or both of those decisions are expected.
Notwithstanding these regulatory developments, the Biden Administration has issued executive orders, could issue additional executive orders and could pursue other legislative and regulatory initiatives that restrict hydraulic fracturing activities on federal lands. For example, the Biden Administration issued an order on January 20, 2021 temporarily suspending the issuance of new leases and authorizations, including drilling permits on federal lands and waters for a period of 60 days, and subsequently issued a second order on January 27, 2021 suspending the issuance of new leases on federal lands and waters pending completion of a study of current oil and gas practices. Further constraints may be adopted by the Biden Administration in the future.
At the state level, many states have adopted legal requirements that have imposed new or more stringent permitting, public disclosure or well construction requirements on hydraulic fracturing activities, including in states where the Company's oil and gas exploration and production activities occur. States could also elect to place prohibitions on hydraulic fracturing and local governments may seek to adopt ordinances within their jurisdictions regulating the time, place or manner of drilling activities in general or hydraulic fracturing activities in particular.
Laws and regulations pertaining to protection of threatened and endangered species or to critical habitat, wetlands and natural resources could delay, restrict or prohibit the Company's operations and cause it to incur substantial costs that may have a material adverse effect on the Company's development and production of reserves.
The federal ESA and comparable state laws were established to protect endangered and threatened species. Under the ESA, if a species is listed as threatened or endangered, restrictions may be imposed on activities adversely affecting that species' habitat. Similar protections are offered to migratory birds under the Migratory Bird Treaty Act ("MBTA"). The U.S. Fish and Wildlife Service ("FWS"), during the Trump Administration, issued a final rule on January 7, 2021, which clarifies that criminal liability under the MBTA will apply only to actions "directed at" migratory birds, its nests, or its eggs; however, in 2020, the U.S. District Court for the Southern District of New York vacated a Department of Interior memorandum articulating a similar interpretation. The Company expects that the January 7 rulemaking will be subject to litigation or to reconsideration by the Biden Administration. 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 delayed, restricted or 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. In addition, the FWS may make new determinations on the listing of species as endangered or threatened under the ESA. The dunes sagebrush lizard is one example of a species that, if listed as endangered or threatened under the ESA in the future, could impact the Company's operations. The designation of previously unprotected species or the re-designation of under protected 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 delays, restrictions or prohibitions on its development and production activities that could have a material adverse effect on the Company's ability to develop and produce reserves.

The Company's transportation of gas, sales and purchases of oil, NGLs and gas or other energy commodities, and any derivative activities related to such energy commodities, expose the Company to potential regulatory risks.
The 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 transportation of gas in interstate commerce, physical sales and purchases of oil, NGL, gas 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 result in agency actions that could materially and adversely affect the Company's results of operations and financial condition.
The enactment of derivatives legislation could have a material 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 in July 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. While many Dodd-Frank Act regulations are already in effect, the rulemaking and implementation process is ongoing, and the ultimate effect of the adopted rules and regulations and any future rules and regulations on the Company's business remain uncertain.
In one of the rulemaking proceedings still pending under the Dodd-Frank Act, the CFTC issued in January 2020 (withdrawing previous proposals from 2013 and 2016), proposed rules imposing position limits for certain futures and options contracts in various commodities (including oil and gas) and for swaps that are their economic equivalents. Under the proposed rules on position limits, certain types of derivative transactions are exempt from these limits, provided that such derivative transactions satisfy the CFTC's requirements for certain enumerated "bona fide" derivative transactions. The CFTC has also adopted final rules regarding aggregation of positions, under which a party that controls the trading of, or owns ten percent or more of the equity interests in, another party will have to aggregate the positions of the controlled or owned party with its own positions for purposes of determining compliance with position limits unless an exemption applies. The CFTC's aggregation rules are now in effect, although CFTC staff has granted relief until August 12, 2022 from various conditions and requirements in the final aggregation rules. These rules may affect both the size of the positions that the Company may hold and the ability or willingness of counterparties to trade with the Company, potentially increasing the costs of transactions. Moreover, such changes could materially reduce the Company's access to derivative opportunities, which could adversely affect revenues or cash flow during periods of low commodity prices. As the 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 to 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 swaps that the Company uses. If the Company's swaps do not qualify for the commercial end-user exception, or if the cost of entering into uncleared swaps becomes prohibitive, the Company may be required to clear such transactions. The ultimate effect of these rules and any additional regulations on the Company's business is uncertain.
In addition, certain banking regulators and the CFTC have adopted final rules establishing minimum margin requirements for uncleared swaps. Although the Company expects to qualify for the end-user exception from margin requirements for swaps entered into to manage its commercial risks, the application of such requirements to other market participants, such as swap dealers, may change the cost and availability of the swaps that the Company uses. If any of the Company's swaps do not qualify for the commercial end-user exception, the posting of collateral could reduce its liquidity and cash available for capital expenditures and could reduce its ability to manage commodity price volatility and the volatility in its cash flows.
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 fully implemented and the market for derivatives contracts has adjusted. In addition, it is possible that the Biden administration could expand regulation of the over-the-counter derivatives market and the entities that participate in that market through either the Dodd-Frank Act or the enactment of new legislation. The Dodd-Frank Act (and any regulations implemented thereunder) and any new legislation could significantly increase the cost of derivative contracts, materially alter the terms of derivative contracts, reduce the availability of derivatives to protect against risks the Company

32

PIONEER NATURAL RESOURCES COMPANY
encounters and reduce the Company's ability to monetize or restructure its existing derivative contracts. Further, 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 materially and adversely affected if a consequence of the Dodd-Frank Act and implementing regulations is to lower commodity prices.
The European Union and other non-U.S. jurisdictions are implementing regulations with respect to the derivatives market. To the extent the Company transacts with counterparties in foreign jurisdictions or counterparties with other businesses that subject them to regulations in foreign jurisdictions, the Company may become subject to, or otherwise affected by, such regulations. At this time, the impact of such regulations is not clear.
Regulation by the CFTC and banking regulators of the over-the-counter derivatives market and market participants could cause the Company's contract counterparties, which are generally financial institutions and other market participants, to curtail or cease their derivatives activities. The Company believes that these regulatory trends have contributed to a reduction in liquidity of the over-the-counter derivatives market, which could make it more difficult to engage in derivative transactions covering significant volumes of the Company's future production, and which could materially and adversely affect the cost and availability of derivatives to the Company. If the Company reduces its use of derivatives as a result of such regulation, the Company's results of operations may become more volatile and its cash flows may be less predictable, which could materially and adversely affect the Company's ability to plan for and fund capital expenditures. Any of these consequences could have a material adverse effect on the Company, its financial condition and its results of operations.
The Company's bylaws provide, to the fullest extent permitted by law, that the Court of Chancery of the State of Delaware (or if the Court of Chancery does not have jurisdiction, the federal district court for the District of Delaware) will be the exclusive forum for certain legal actions between the Company and its stockholders and that the federal district courts of the United States shall be the sole and exclusive forum for the resolution of causes of action arising under the Securities Act of 1933. These provisions could increase costs to bring a claim, discourage claims or limit the ability of the Company's stockholders to bring a claim in a judicial forum viewed by the stockholders as more favorable for disputes with the Company or the Company's directors, officers or other employees.
The Company's bylaws provide to the fullest extent permitted by law that, unless the Company consents in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware (or if the Court of Chancery does not have jurisdiction, the federal district court for the District of Delaware) will be the sole and exclusive forum for (a) any derivative action or proceeding brought on behalf of the Company, (b) any action asserting a claim of breach of a fiduciary duty owed by any director, officer, other employee or agent or stockholder of the Company to the Company or the Company's stockholders, (c) any action against the Company arising pursuant to any provision of the Delaware General Corporation Law or as to which the Delaware General Corporation Law confers jurisdiction on the Court of Chancery of the State of Delaware, or (d) any action against the Company or any director, officer, other employee or agent of the Company asserting a claim governed by the internal affairs doctrine, including, without limitation, any action to interpret, apply, enforce or determine the validity of the Company's certificate of incorporation or the Company's bylaws. The Company's bylaws also provided that the federal district courts of the United States shall be the sole and exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act of 1933. Although the Company's bylaws provide for an exclusive forum for causes of action under the Securities Act of 1933, its stockholders will not be deemed to have waived compliance with the federal securities laws and the rules and regulations thereunder. The choice of forum provisions may increase costs to bring a claim, discourage claims or limit a stockholder's ability to bring a claim in a judicial forum that it finds favorable for disputes with the Company or the Company's directors, officers or other employees, which may discourage such lawsuits against the Company or the Company's directors, officers and other employees. Alternatively, if a court were to find the choice of forum provision contained in the Company's bylaws to be inapplicable or unenforceable in an action, the Company may incur additional costs associated with resolving such action in other jurisdictions.
Risks associated with the Parsley Acquisition.
The financial and operational synergies attributable to the Parsley Acquisition may vary from expectations.
Pioneer may fail to realize the anticipated benefits and synergies expected from the Parsley Acquisition, which could adversely affect its business, financial condition and operating results. The success of the Parsley Acquisition will depend, in significant part, on Pioneer's ability to successfully integrate the acquired business and realize the anticipated strategic benefits and synergies from the combination. Pioneer believes that the addition of Parsley will complement Pioneer's strategy by providing operational and financial scale, increasing free cash flow and enhancing Pioneer's corporate rate of return. However, achieving these goals requires, among other things, realization of the targeted cost synergies expected from the Parsley Acquisition. The anticipated benefits of the transaction may not be realized fully or at all, or may take longer to realize than expected. Actual operating, technological, strategic and revenue opportunities, if achieved at all, may be less significant than

33

PIONEER NATURAL RESOURCES COMPANY
expected or may take longer to achieve than anticipated. If Pioneer is not able to achieve these objectives and realize the anticipated benefits and synergies expected from the Parsley Acquisition within the anticipated timing or at all, Pioneer's business, financial condition and operating results may be adversely affected.
Litigation relating to the Parsley Acquisition could result in substantial costs to the Company.
Securities class action lawsuits and derivative lawsuits are often brought against public companies that have entered into acquisition, merger or other business combination agreements. Even if such a lawsuit is without merit, defending against these claims can result in substantial costs and divert the time and resources of management. An adverse judgment could result in monetary damages, which could have a negative impact on the Company's liquidity and financial condition.
The Company, subsidiaries, or persons that have indemnification rights against the Company or its subsidiaries have been sued in connection with the Parsley Acquisition. There can be no assurance that the Company and the other defendants will be successful in the outcome of any such pending or any potential future lawsuits. The defense or settlement of any of these pending or future lawsuits may adversely affect the Company's business, liquidity, financial condition and results of operations.
The Company may be unable to integrate the business of Parsley successfully and/or realize the anticipated benefits of the Parsley Acquisition.
The Parsley Acquisition involves the combination of two companies that operated as independent public companies. The combination of two independent businesses is complex, costly and time consuming, and the Company will be required to devote significant management attention and resources to integrating Parsley's business practices and operations with those of the Company. Potential difficulties that the Company may encounter as part of the integration process include the following:
the inability to successfully combine the business of Parsley in a manner that permits the Company to achieve, on a timely basis or at all, the enhanced revenue opportunities, cost savings and other benefits anticipated to result from the Parsley Acquisition;
complexities associated with managing the combined businesses, including difficulty addressing possible differences in operational philosophies and the challenge of integrating complex systems, technology, networks and other assets of each of the companies in a seamless manner that minimizes any adverse impact on the customers, suppliers, employees and other constituencies;
the assumption of contractual obligations with less favorable or more restrictive terms;
potential unknown liabilities and unforeseen increased expenses associated with the Parsley Acquisition;
diversion of the attention of the Company's management; and
the disruption of, or the loss of momentum in, the Company's ongoing business or inconsistencies in standards, controls, procedures and policies.
Any of these issues could adversely affect the Company's ability to maintain relationships with customers, suppliers, employees and other constituencies or achieve the anticipated benefits of the Parsley Acquisition, or could reduce the Company's earnings or otherwise adversely affect the Company's business and financial results.
The Company's future results will suffer if it does not effectively manage its expanded operations.
As a result of the Parsley Acquisition, the size and geographic footprint of the Company's business has increased. The Company's future success will depend, in part, upon its ability to manage this expanded business, which may pose substantial challenges for management, including challenges related to the management and monitoring of new operations and basins and associated increased costs and complexity. The Company may also face increased scrutiny from governmental authorities as a result of the increase in the size of its business. There can be no assurances that the Company will be successful or that it will realize the expected operating efficiencies, cost savings, revenue enhancements or other benefits currently anticipated from the Parsley Acquisition.

Reserve Estimation Procedures and Audits
The information included in this Report about the Company's proved reserves as of December 31, 2020, 2019 and 2018 is based on evaluations prepared by the Company's engineers and audited by Netherland, Sewell & Associates, Inc. ("NSAI").
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 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.
Corporate Reserves is staffed with reservoir engineers and geoscientists who prepare reserve estimates using reservoir engineering information technology. Corporate Reserves interacts with the exploration and production functions to ensure all available engineering and geologic data is taken into account prior to establishing or revising an estimate. There is oversight of the reservoir engineers by the Director of Reserves who is in turn subject to direct oversight by the Company's management committee ("MC") which is comprised of its Chief Executive Officer, Chief Operating Officer, Chief Financial Officer and other executive officers.
All reserve estimates, material assumptions and inputs used in reserve estimates and significant changes in reserve estimates are reviewed for appropriateness and compliance with SEC rules and U.S. GAAP. Annually, the MC reviews the reserve estimates, and any differences with NSAI for the portion of the reserves that it audits, 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 through internal Pioneer programs. Additionally, Corporate Reserves has prepared and maintains written policies and guidelines for its staff to reference on reserve estimation and preparation to promote consistency in the preparation of the Company's reserve estimates and compliance with the SEC reserve estimation and reporting rules.
Proved reserves audits. The proved reserves audited by NSAI, in aggregate, represented the following:
As of December 31,
2020 2019 2018
Proved reserves audited by NSAI 89  % 83  % 79  %
Pre-tax present value of proved reserves discounted at ten percent audited by NSAI 100  % 99  % 95  %
In connection with the annual reserves audit, NSAI prepared its own estimates of the Company's proved reserves and compared its estimates to those prepared by the Company. NSAI determined that the Company's estimates of reserves were prepared in accordance with the definitions and regulations of the SEC, including the criteria of "reasonable certainty," as it pertains to expectations about the recoverability of reserves in future years, under existing economic and operating conditions, consistent with the definition in Rule 4-10(a)(24) of Regulation S-X. NSAI issued an unqualified audit opinion on the Company's proved reserves at December 31, 2020, 2019 and 2018, respectively, based upon their evaluation. NSAI concluded that the Company's estimates of proved reserves were, in the aggregate, reasonable and had been prepared in accordance with Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information promulgated by the Society of Petroleum Engineers. NSAI's report as of December 31, 2020, which should be read in its entirety, is attached as Exhibit 99.1 to this Annual Report on Form 10-K.
Qualifications of proved reserves preparers and auditors. Corporate Reserves is staffed by petroleum engineers with extensive industry experience and is managed by the Director of Reserves, the technical person who is primarily responsible for overseeing the Company's reserves estimates. These individuals meet the professional qualifications of reserves estimators and reserves auditors as defined by the Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information. The qualifications of the Director of Reserves include 41 years of international and domestic experience as a petroleum engineer, with 23 years focused on reserves reporting for independent oil and gas companies, including Pioneer. He has an additional 19 years of Permian Basin-focused production engineering, advanced reservoir engineering, petrophysics, consulting and special project research experience with major oil companies. His educational background includes an undergraduate degree in Geological Engineering with a Petroleum Engineering emphasis.

Technologies used in proved 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 certainty that the results will be consistent and repeatable 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.

With approximately 755,000 gross acres (680,000 net acres), Pioneer is the largest acreage holder in the Spraberry/Wolfcamp field in the Permian Basin of West Texas. Pioneer's interests in the northern portion of the play comprise approximately 560,000 gross acres and its interests in the southern portion of the play, where the Company has a joint venture with Sinochem, comprise approximately 200,000 gross acres. The January 12, 2021 Parsley Acquisition added approximately 290,000 gross acres to the Company's acreage position in the Permian Basin, of which approximately 190,000 gross acres are in the Midland Basin and approximately 100,000 gross acres are in the Delaware Basin. The oil produced from the Permian Basin 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 seven formations, the Spraberry, the Jo Mill, the Dean, the Wolfcamp, Bone Spring, the Strawn and the Atoka, at depths ranging from 7,500 feet to 14,000 feet. The Company believes that it has significant resource potential within its Spraberry, Jo Mill, Wolfcamp and Bone Spring formation acreage, based on the Company and Parsley's extensive geologic data covering the Middle Spraberry, Jo Mill and Lower Spraberry intervals, the Wolfcamp A, B, C and D intervals and the Bone Spring intervals and both the Company and Parsley's drilling results to date.

During 2020, the Company successfully completed 206 horizontal wells in the northern portion of the play where approximately 40 percent of the horizontal wells placed on production were Wolfcamp A interval wells, approximately 30 percent were Wolfcamp B interval wells and approximately 30 percent were Spraberry and Wolfcamp D interval wells. Additionally, the Company successfully completed 49 horizontal wells in the southern portion of the play where the majority of the wells placed on production were Wolfcamp B interval wells.
The Company continues to complete acreage trades that allow the Company to drill wells with longer laterals, improving the expected returns of the wells. The Company estimates that the acreage trades completed in 2020 added approximately 4 million lateral feet to the Company's drilling inventory.
The Company plans to operate an average of 18 to 20 drilling rigs in the Permian Basin in 2021, with an average of 15 to 17 rigs operating in the northern portion of the Midland Basin, three rigs operating in the southern portion of the Midland Basin and one rig operating in the Delaware Basin on the acquired acreage from Parsley. During 2021, for the Midland Basin, the Company expects approximately 40 percent of its planned horizontal wells to be drilled in the Wolfcamp B interval, 40 percent in the Wolfcamp A interval, 15 percent in the Spraberry intervals and the remaining five percent in the Delaware Basin. The Company expects its Delaware Basin drilling activity to target approximately 60 percent of its planned horizontal wells to be drilled in the Wolfcamp A and B intervals and approximately 40 percent in the Bone Spring intervals.
Selected Oil and Gas Information
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, as evidenced by the significant demand reduction during 2020 as a result of the COVID-19 pandemic, 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 decline in oil, NGL and 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 the capital markets.
The following tables set forth production, price and cost data with respect to the Company's properties. These amounts represent the Company's historical results of 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. 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.

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 2020 included the following highlights:
Net loss attributable to common stockholders was $200 million ($1.21 per diluted share) for the year ended December 31, 2020, as compared to net income of $773 million ($4.59 per diluted share) in 2019. The primary components of the $973 million decrease in net income (loss) attributable to common stockholders include:
a $1.3 billion decrease in oil and gas revenues, primarily due to a 31 percent decrease in average realized commodity prices per BOE, partially offset by a six percent increase in daily sales volumes due to the Company's successful horizontal drilling program in the Permian Basin;
a $522 million decrease in net sales of purchased commodities due to a decrease in margins on the Company's downstream Gulf Coast refinery and export oil sales;
a $336 million decrease in derivative results, primarily due to changes in forward commodity prices and the cash settlement of derivative positions in accordance with their terms; and
a $143 million decrease in interest and other income (loss), primarily related to noncash valuation adjustments associated with the Company's investment in an affiliate, net proceeds received in 2019 from the sale of the Company's investment in its corporate headquarters and a decrease in interest income.
Partially offset by:
a $486 million increase in the gain (loss) on disposition of assets (from a net loss on disposition of assets in 2019 to a net gain on disposition of assets in 2020), primarily due to the 2019 net loss recorded on the divestiture of the Company's Eagle Ford assets and other remaining South Texas assets in May 2019 (the "South Texas Divestiture");
a $296 million reduction in income taxes primarily due to the decrease in earnings between 2020 and 2019;
a $249 million decrease in production costs, including taxes, primarily attributable to (i) the Company's cost saving initiatives to lower production costs and (ii) the reduction in production taxes as a result of the aforementioned 31 percent decrease in average realized commodity prices per BOE;
a $127 million decrease in other expense, primarily related to decreases of (i) $80 million in employee-related charges associated with the 2020 and 2019 corporate restructurings and the Company's 2020 staffing reduction in its well services business, (ii) $83 million related to asset divestitures, decommissioning and impairments, (iii) $58 million in firm transportation charges on excess pipeline capacity commitments and (iv) $42 million in corporate headquarters relocation-related costs, partially offset by increases of (i) $80 million in the Company's net forecasted deficiency fee obligation and receivable associated with the South Texas Divestiture, (ii) $55 million in idle frac fleet fees, stacked drilling rig charges and drilling rig early terminations charges and (iii) $27 million in early extinguishment of debt charges;
an $80 million decrease in general and administrative expense primarily due to (i) the effect of the Company's 2019 and 2020 corporate restructurings, which resulted in employee headcount reductions and decreased salaries and benefits and (ii) the Company's reduction of additional overhead related costs during 2020 through voluntary salary reductions by the Company's officers and board of directors, reductions in estimated cash incentive compensation, benefit reductions and other cash cost reductions as a result of the Company's response to the COVID-19 pandemic's impact on oil demand and prices; and
a $72 million decrease in DD&A expense, primarily due to additions to proved reserves attributable to the Company's successful Spraberry/Wolfcamp horizontal drilling program.
During 2020, average daily sales volumes increased on a BOE basis by six percent to 367,253 BOEPD, as compared to 345,518 BOEPD during 2019, primarily due to the Company's successful Spraberry/Wolfcamp horizontal drilling program.
Average oil and NGL prices decreased per Bbl in 2020 to $37.24 and $15.62, respectively, as compared to $53.77 and $19.33, respectively, in 2019. Average gas prices decreased per Mcf in 2020 to $1.73 as compared to $1.79 in 2019.
Parsley Acquisition
The Company completed the Parsley Acquisition on January 12, 2021. Parsley's results of operations will be consolidated with the Company's interim consolidated financial statements beginning on January 12, 2021. See Item 1.
Business - Acquisition Activities" and Note 19 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.
First Quarter 2021 Outlook
The first quarter of 2021 is expected to continue to have a high degree of uncertainty related to how long it will take to return to a balanced oil supply and demand environment. As a result, the Company's future operating and financial results will depend on various factors beyond the Company's control, such as: the duration of the COVID-19 pandemic and the speed and effectiveness of vaccine distributions to combat the virus, which is expected to directly impact the recovery of world economic growth and the demand for oil; the impact of U.S. energy, monetary, environmental and trade policies; fiscal challenges facing the United States federal government; geopolitical issues globally, especially in the Middle East; the extent to which OPEC members and some nonmembers, including Russia, adhere to and agree to extend cuts to their oil production quotas; and uncertainty in oil demand fundamentals associated with governmental policy aimed at redirecting fossil fuel consumption towards lower carbon energy.
Based on current estimates, the Company expects the following operating and financial results for the first quarter of 2021, which includes the effects of the Parsley Acquisition (from the date of acquisition) and the February 2021 winter storms in West Texas:
Three Months Ending March 31, 2021
Preliminary Guidance
($ in millions, except per BOE amounts)
Average daily production (MBOE) 444 - 470
Average daily oil production (MBbls) 259 - 274
Production costs per BOE $6.50 - $8.00
DD&A per BOE $11.25 - $13.25
Exploration and abandonments expense $10 - $20
General and administrative expense $65 - $75
Accretion of discount on asset retirement obligations $2 - $5
Interest expense $38 - $43
Other expense $10 - $20
Cash flow impact from firm transportation (a) $(60) - $(30)
Current income tax provision (benefit) <$5
Effective tax rate 21% - 25%
_____________________
(a)The cash flow impact from firm transportation is primarily based on the forecasted differential between WTI oil prices and Brent oil prices less the costs to transport purchased oil from the areas of the Company's production to the Gulf Coast. To the extent that the Company's Gulf Coast sales of purchased oil does not cover the purchase price and associated firm transport costs, the Company's results of operations will reflect the negative cashflow impact attributable to its firm transportation commitments.
During February 2021, the Company's operations in West Texas were significantly impacted by winter weather that brought abnormally cold temperatures, along with snow and icy conditions across the state of Texas. The extreme winter weather impacted production operations, midstream infrastructure and power providers throughout the state, along with many other services. As a result, most of the Company's production was offline for about a week. Early in the weather event, the Company attempted to perform or otherwise satisfy its firm gas sales commitments, but as the impacts of the winter weather became clearer, the Company subsequently issued force majeure notices to its customers given the inability to perform such contracts for a variety of reasons, including significant production being offline, interruptions to midstream operations, the inability to flow gas to markets due to infrastructure downtime and compliance with government orders to direct any available gas volumes towards supporting power generation. Certain of the Company's customers have alleged that the Company's force majeure notices were improper under the applicable contracts. The Company estimates that it incurred incremental cash costs of $75 million to $85 million in connection with its firm gas sales commitments early in the weather event.
2021 Capital Budget
The Company's capital budget for 2021 is expected to be in the range of $2.5 billion to $2.8 billion, consisting of $2.3 billion to $2.6 billion for drilling and completion related activities, including additional tank batteries and saltwater disposal facilities, $100 million of estimated Parsley integration costs and $90 million for water infrastructure, well services and vehicles. The 2021 capital budget excludes acquisitions, asset retirement obligations, capitalized interest and geological and geophysical general and administrative expense and corporate facilities.

The 2021 capital budget is expected to be funded from operating cash flow, and, if necessary, from cash and cash equivalents on hand or borrowings under the Company's credit facility.
Divestitures, Decommissioning and Restructuring Activities
Divestitures.
In May 2020, the Company completed the sale of certain vertical wells and approximately 1,500 undeveloped acres in Upton County of the Permian Basin to an unaffiliated third party for net cash proceeds of $6 million. The Company recorded a gain of $6 million associated with the sale.
In December 2019, the Company completed the sale of certain vertical and horizontal wells and approximately 4,500 undeveloped acres in Glasscock County of the Permian Basin to an unaffiliated third party for net cash proceeds of $64 million. The Company recorded a gain of $10 million associated with the sale.
In July 2019, the Company completed the sale of certain vertical wells and approximately 1,400 undeveloped acres in Martin County of the Permian Basin to an unaffiliated third party for net cash proceeds of $27 million. The Company recorded a gain of $26 million associated with the sale.
In June 2019, the Company completed the sale of certain vertical wells and approximately 1,900 undeveloped acres in Martin County of the Permian Basin to an unaffiliated third party for net cash proceeds of $38 million. The Company recorded a gain of $31 million associated with the sale.
In May 2019, the Company completed the South Texas Divestiture to an unaffiliated third party in exchange for total consideration having an estimated fair value of $210 million. The fair value of the consideration included (i) net cash proceeds of $2 million, (ii) $136 million in contingent consideration and (iii) a $72 million receivable associated with estimated deficiency fees to be paid by the buyer. The Company recorded a loss of $525 million and recognized employee-related charges of $19 million associated with the sale.
Contingent Consideration. Per the terms of the South Texas Divestiture, the Company was entitled to receive contingent consideration based on future annual oil and NGL prices during each of the five years from 2020 to 2024. The Company revalued the contingent consideration using an option pricing model each reporting period prior to the settlement of the contingent consideration in July 2020 when the Company received cash proceeds of $49 million from the buyer to fully satisfy the contingent consideration. The Company recorded a noncash loss of $42 million to interest and other income during the year ended December 31, 2020 associated with the settlement.
Deficiency Fee Obligation. The Company transferred its long-term midstream agreements and associated minimum volume commitments ("MVC") to the buyer. However, the Company retained the obligation to pay 100 percent of any deficiency fees associated with the MVC from January 2019 through July 2022. The Company determines the fair value of the deficiency fee obligation using a probability weighted discounted cash flow model. The deficiency fee obligation is included in current or noncurrent liabilities in the consolidated balance sheets, based on the estimated timing of payments. During the year ended December 31, 2020, the Company recorded a charge of $84 million in other expense in the consolidated statements of operations, to increase the Company's forecasted deficiency fee payments as a result of a reduction in planned drilling activities by the buyer of the assets. The estimated remaining deficiency fee obligation was $333 million as of December 31, 2020.
Deficiency Fee Receivable. The buyer is required to reimburse the Company for 18 percent of the deficiency fees paid under the transferred midstream agreements from January 2019 through July 2022. Such reimbursement will be paid by the buyer in installments beginning in 2023 through 2025. The Company determines the fair value of the deficiency fee receivable using a credit risk-adjusted valuation model. During the year ended December 31, 2020, the Company recorded an increase to the Company's long-term deficiency fee receivable of $4 million in other expense in the consolidated statements of operations, to reflect the buyer's share of 2020 deficiency fees which were greater than originally forecasted as of the date of the sale. The deficiency fee receivable is included in noncurrent other assets in the consolidated balance sheets.
Decommissioning.
In November 2018, the Company announced plans to close its sand mine located in Brady, Texas and transition its proppant supply requirements to West Texas sand sources.
During 2019, the Company recorded $23 million of accelerated depreciation, $13 million of inventory and other property and equipment impairment charges and $12 million of sand mine closure-related costs.

PIONEER NATURAL RESOURCES COMPANY
During 2018, the Company recorded $443 million of accelerated depreciation and $7 million of employee-related charges associated with the shutdown.
Restructuring.
During the third quarter of 2020, the Company announced a corporate restructuring to reduce its staffing levels to correspond with a planned reduction in future activity levels. The restructuring resulted in approximately 300 employees being involuntarily separated from the Company in October 2020. The Company recorded $78 million of employee-related charges, including $5 million of noncash stock-based compensation expense related to the accelerated vesting of certain equity awards, in other expense in the consolidated statements of operations during the year ended December 31, 2020. See Note 3, Note 8 and Note 16 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.
In June 2020, the Company implemented changes to its well services business, including a staffing reduction of approximately 50 employees. The changes were made to more closely align the well services cost structure and headcount with the Company's reduction in expected activity levels as a result of the COVID-19 pandemic's impact on oil prices. The Company recorded $1 million of employee-related charges in other expense in the consolidated statements of operations during the year ended December 31, 2020 related to the staffing reductions in its well services business.
During 2019, the Company implemented a corporate restructuring to align its cost structure with the needs of a Permian Basin-focused company (the "2019 Corporate Restructuring Program"). The 2019 Corporate Restructuring Program occurred in three phases as follows:
In March 2019, the Company made certain changes to its leadership and organizational structure, which included the early retirement and departure of certain officers of the Company,
In April 2019, the Company adopted a voluntary separation program ("VSP") for certain eligible employees, and
In May 2019, the Company implemented an involuntary separation program ("ISP").
During 2019, the Company recorded $159 million of employee-related charges, including $26 million of noncash stock-based compensation expense related to the accelerated vesting of certain equity awards, associated with the 2019 Corporate Restructuring Program.
See Note 3 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information regarding Divestitures, Decommissioning and Restructuring activities.
Results of Operations
Results of operations should be read together with the Company's consolidated financial statements and related notes included in "Item 8. Financial Statements and Supplementary Data" of this Annual Report on Form 10-K. See the Company's Annual Report on Form 10-K for the year ended December 31, 2019 for a discussion of the Company's 2019 results of operations as compared to the Company's 2018 results of operations.
Oil and gas revenues. The Company's revenues are derived from sales of oil, NGL and gas production. Increases or decreases in the Company's revenues, profitability and future production are highly dependent on commodity prices. Prices are market driven and future prices will fluctuate due to supply and demand factors, availability of transportation, seasonality, geopolitical developments and economic factors, among other items.

Average daily sales volumes are as follows:
  Year Ended December 31,
  2020 2019 % Change

Total (BOE) 367,253  345,518  %
____________________
(a)Gas production excludes gas produced and used as field fuel.
Average daily sales volumes per BOE increased for the year ended December 31, 2020, as compared to 2019, primarily due to the Company's successful Spraberry/Wolfcamp horizontal drilling program. The increase in NGL and gas volumes primarily reflects (i) increasing wet gas production (as a percentage of a horizontal wells total production) over time, (ii) new processing facilities and takeaway capacity being placed into service during 2019 and 2020, which had the effect of lowering line pressures and (iii) increased recovery rates for NGLs. The decrease in oil volumes for the year ended December 31, 2020, as compared to 2019, was primarily due to the Company's reduced drilling and completion activity and proactively curtailing lower-margin, higher-cost vertical well production during 2020 as a result of the reduced oil price environment.
The oil, NGL and gas prices reported by the Company are based on the market prices received for each commodity. The average prices are as follows:
  Year Ended December 31,
  2020 2019 % Change
Oil per Bbl $ 37.24  $ 53.77  (31  %)
NGLs per Bbl $ 15.62  $ 19.33  (19  %)
Gas per Mcf $ 1.73  $ 1.79  (3  %)
Total per BOE $ 27.01  $ 38.98  (31  %)
Sales of purchased commodities. The Company enters into purchase transactions with third parties and separate sale transactions with third parties to diversify a portion of the Company's oil and gas sales to (i) Gulf Coast refineries, (ii) Gulf Coast and West Coast gas markets and (iii) international oil markets and to satisfy unused gas pipeline capacity commitments. Revenues and expenses from these transactions are generally presented on a gross basis as the Company acts as a principal in the transaction by assuming both the risks and rewards of ownership, including credit risk, of the commodities purchased and the responsibility to deliver the commodities sold. In conjunction with the Company's downstream sales, the Company also enters into pipeline capacity commitments in order to secure available oil, NGL and gas transportation capacity from the Company's areas of production to downstream sales points. The transportation costs associated with these transactions are included in purchased commodities expense.
The net effect of third party purchases and sales of commodities is as follows:
Year Ended December 31,
2020 2019 Change
(in millions)
Sales of purchased commodities $ 3,394  $ 4,755  $ (1,361)
Purchased commodities 3,633  4,472  (839)
Net effect on earnings $ (239) $ 283  $ (522)
The $522 million decrease in net sales of purchased commodities for the year ended December 31, 2020, as compared to 2019, is primarily due to (i) a $74 million loss during the first quarter of 2020 attributable to oil that was purchased and in transit via pipeline to the Gulf Coast or in Gulf Coast storage at the end of January and February, and was subsequently sold in February 2020 and March 2020, respectively, at lower prices (this oil inventory is sold in the following month at contracted prices that are generally tied to monthly average index oil prices (typically Brent oil prices)) and (ii) a decrease in 2020 margins on the Company's downstream Gulf Coast refinery and export oil sales.
Firm transportation payments on excess pipeline capacity are included in other expense in the accompanying consolidated statements of operations. See Note 16 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.

_____________________
(a)Lease operating expense and workover costs represent the components of oil and gas production costs over which the Company has management control.
(b)Gathering, processing and transportation expense represents the costs to gather, process, fractionate and transport the Company's gas and NGLs to their point of sale.
(c)Net natural gas plant income represents the earnings from the Company's ownership share of gas processing facilities that gather and process the Company's and third party gas.
Lease operating expense per BOE decreased for the year ended December 31, 2020, as compared to 2019, primarily due to (i) the Company's cost saving initiatives to lower production costs and (ii) the impact of the sale of the Company's South Texas assets in May 2019, which had a higher lease operating expense per BOE than the Company's Permian Basin assets. Gathering, processing and transportation expense per BOE increased due to a higher proportion of the Company's total production being attributable to gas and NGL production, higher NGL recoveries and incremental costs associated with new processing facilities and pipeline takeaway capacity for the Company's gas and NGL production. Workover costs per BOE decreased primarily due to reduced workover activity as a result of lower commodity prices being realized in 2020, which reduced the economic benefit of repairing many of the Company's marginal vertical wells. Net natural gas plant income per BOE increased primarily due to new processing facilities brought online in 2019 and 2020 that resulted in higher NGL recoveries and reduced plant operating expenses.

The decrease in geological and geophysical costs for the year ended December 31, 2020, as compared to 2019, is primarily due to a decrease in geological and geophysical personnel costs as a result of (i) the 2020 cost reduction initiatives in response to the COVID-19 pandemic, (ii) the 2020 Corporate Restructuring and (iii) the 2019 Corporate Restructuring Program (collectively the "2019 and 2020 Overhead Cost Reduction Initiatives"). The increase in leasehold abandonment costs is primarily due to the abandonment of certain unproved properties that the Company no longer plans to drill before the leases expire.
During 2020 and 2019, the Company completed and evaluated 242 and 281 exploration/extension wells, respectively, and 100 percent and 96 percent, respectively, were successfully completed as discoveries.

$ 1.82  $ 2.57  (29  %)
The decrease in noncash general and administrative expense per BOE for the year ended December 31, 2020, as compared to 2019, is primarily due to market fluctuations in the Company's deferred compensation obligation as a result of mark-to-market valuation changes attributable to the Company's deferred compensation plan assets and a decrease in employee share-based compensation amortization due to reduced staffing levels associated with the 2019 and 2020 Overhead Cost Reduction Initiatives.
The decrease in cash general and administrative expense per BOE for the year ended December 31, 2020, as compared to 2019, is primarily due to a decrease in corporate staffing levels and the Company's 2019 and 2020 Overhead Cost Reduction Initiatives.

Cash interest expense 78  112  (34)
$ 129  $ 121  $
The increase in noncash interest expense for the year ended December 31, 2020, as compared to 2019, is primarily due to (i) amortization of the discount attributable to the issuance of convertible senior notes in May 2020 that was recorded to additional paid-in capital in the accompanying consolidated balance sheets and (ii) accretion associated with the Company's corporate headquarters that was capitalized as a finance lease in November 2019.
The decrease in cash interest expense is primarily due to the repayment of $450 million of 7.50% senior notes that matured in January 2020 and the Company's partial repayment of $360 million of its 3.45% senior notes due 2021, $356 million of its 3.95% senior notes due 2022 and $9 million of its 7.20% senior notes due 2028 as a result of the Company's tender offer for these notes in May 2020, partially offset by the issuance in May 2020 and August 2020, respectively, of $1.3 billion of 0.25% convertible senior notes due 2025 and $1.1 billion of 1.90% senior notes due 2030.
The weighted average cash interest rate on the Company's indebtedness for the year ended December 31, 2020 decreased to 2.2 percent, as compared to 5.0 percent for the year ended December 31, 2019.

Liquidity and Capital Resources
Liquidity. In response to the COVID-19 pandemic, the Company implemented measures to reduce, defer or cancel certain planned capital expenditures and reduce its overall cost structure commensurate with its expected level of activities. Additionally, as described in financing activities below, the Company enhanced its liquidity position by refinancing a portion of its existing debt and issuing new debt, with the combined objective of increasing liquidity, extending the Company's debt maturities and lowering the Company's future cash interest expense on long-term debt.
The Company's primary sources of short-term liquidity are (i) cash and cash equivalents, (ii) net cash provided by operating activities, (iii) sales of investments, (iv) unused borrowing capacity under its credit facility (the "Credit Facility"), (v) issuances of debt or equity securities and (vi) other sources, such as sales of nonstrategic assets. In January 2021, Pioneer entered into the First Amendment to Credit Agreement, with the primary changes being to increase the aggregate loan commitments from $1.5 billion to $2.0 billion, extend the maturity of the credit facility to January 12, 2026 and to nominally adjust the drawn and undrawn pricing.
The Company's short-term and long-term liquidity requirements consist primarily of (i) capital expenditures, (ii) acquisitions of oil and gas properties, (iii) payments of contractual obligations, including debt maturities, (iv) dividends and share repurchases and (v) working capital obligations. Funding for these requirements may be provided by any combination of the Company's sources of liquidity. Although the Company expects that its sources of funding will be adequate to fund its 2021 liquidity requirements, no assurance can be given that such funding sources will be adequate to meet the Company's future needs.     
Capital resources.
See the Company's Annual Report on Form 10-K for the year ended December 31, 2019 for a discussion of the Company's 2019 capital resources as compared to the Company's 2018 capital resources.
As of December 31, 2020, the Company had no outstanding borrowings under its Credit Facility, and was in compliance with all of its debt covenants. The Company also had unrestricted cash on hand of $1.4 billion as of December 31, 2020.

Sources and uses of cash in 2020, as compared to 2019, are as follows:
Year Ended December 31,
2020 2019 Change
(in millions)
Net cash provided by operating activities $ 2,083  $ 3,115  $ (1,032)
Net cash used in investing activities $ (1,668) $ (2,447) $ (779)
Net cash provided by (used in) financing activities $ 381  $ (788) $ 1,169 
Operating activities. The decrease in net cash flow provided by operating activities in 2020, as compared to 2019, is primarily due to (i) decreases in the Company's oil and NGL revenues as a result of decreases in commodity prices and (ii) a $522 million decrease in net sales of purchased oil and gas due to a decrease in margins on the Company's downstream Gulf Coast refinery and export oil sales, partially offset by the Company's overall lower cost structure due to its operating cost reduction efforts and its 2019 and 2020 Overhead Cost Reduction Initiatives.
Investing activities. The decrease in net cash flow used in investing activities during 2020, as compared to 2019, is primarily due to decreases in additions to oil and gas properties and additions of other assets and other property and equipment of $1.5 billion. The reduction in 2020 investing activities reflects the Company's reduced capital budget and cost reduction efforts, partially offset by a decrease in the sale of investments and the disposition of assets of $624 million and $89 million, respectively. The Company's investing activities during the year ended December 31, 2020 were primarily funded by net cash provided by operating activities.
Financing activities. The Company's significant financing activities are as follows:
2020: The Company (i) received $1.1 billion from the issuance of 1.90% senior notes, net of issuance costs and discounts, (ii) received $1.3 billion from the issuance of the 0.25% convertible senior notes, net of issuance fees, (iii) paid $113 million to enter into capped call transactions with certain financial institution counterparties associated with the convertible senior notes issuance, (iv) paid an aggregate total of $748 million associated with the early repayment of a portion of the 3.45% senior notes, 3.95% senior notes and 7.20% senior notes, (v) repaid $450 million associated with the maturity of its 7.50% senior notes in January 2020, (vi) paid dividends of $346 million, (vii) repurchased $176 million of its common stock and (viii) paid $173 million of other liabilities.
2019: The Company repurchased $653 million of its common stock and paid dividends of $127 million.
Dividends/distributions. During the year ended December 31, 2020, the Company's board of directors declared dividends of $2.20 per common share, compared to dividends declared of $1.20 per common share during the year ended December 31, 2019. The Company paid aggregate dividends of $346 million during 2020 and $127 million during 2019. Future dividends are at the discretion of the Company's board of directors, and, if declared, the board of directors may change the dividend amount based on the Company's liquidity and capital resources at the time.
Off-balance sheet arrangements. From time to time, the Company enters into arrangements and transactions that can give rise to material off-balance sheet obligations of the Company. As of December 31, 2020, the material off-balance sheet arrangements and transactions that the Company had entered into included (i) firm purchase, transportation, storage and fractionation commitments, (ii) open purchase commitments and (iii) contractual obligations for which the ultimate settlement amounts are not fixed and determinable. The contractual obligations for which the ultimate settlement amounts are not fixed and determinable include (i) derivative contracts that are sensitive to future changes in commodity prices or interest rates, (ii) gathering, processing (primarily treating and fractionation) and transportation commitments on uncertain volumes of future throughput and (iii) indemnification obligations following certain divestitures.
In connection with its divestiture transactions, the Company may retain certain liabilities and provide the purchaser certain indemnifications, subject to defined limitations, which may apply to identified pre-closing matters, including matters of litigation, environmental contingencies, royalty and income taxes. Also associated with its divestiture transactions, the Company has issued and received guarantees to facilitate the transfer of contractual obligations, such as firm transportation agreements or gathering and processing arrangements. The Company does not recognize a liability if the fair value of the obligation is immaterial and the likelihood of making payments under these guarantees is remote.
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. The Company expects to enter into similar contractual arrangements in the future, including incremental derivative contracts and additional firm purchase, transportation, storage and fractionation

arrangements, in order to support the Company's business plans. See Note 11 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.
Contractual obligations. The Company's contractual obligations include long-term debt, operating leases (primarily related to contracted drilling rigs, equipment and office facilities), capital funding obligations, derivative obligations, firm transportation, storage and fractionation commitments, minimum annual gathering, processing and transportation commitments and other liabilities (including postretirement benefit obligations). Other joint owners in the properties operated by the Company could incur portions of the costs represented by these commitments.
Firm commitments. The Company has short-term and long-term firm purchase, gathering, processing, transportation, fractionation and storage commitments representing take-or-pay agreements, which include contractual commitments (i) to purchase sand, water and diesel for use in the Company's drilling operations, (ii) with midstream service companies and pipeline carriers for future gathering, processing, transportation, fractionation and storage and (iii) with oilfield services companies that provide drilling and pressure pumping services. The Company does not expect to be able to fulfill all of its short-term and long-term firm transportation volume obligations from projected production of available reserves; consequently, the Company plans to purchase third party volumes to satisfy its firm transportation commitments if it is economic to do so; otherwise, it will pay demand fees for any commitment shortfalls. The Company also has open purchase commitments for inventories, materials and other property and equipment ordered, but not received, as of December 31, 2020. See "Item 2. Properties" and Note 11 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.
Long-term debt. As of December 31, 2020, the Company's outstanding debt is comprised of senior notes and convertible senior notes. The senior notes and convertible senior notes are unsecured obligations ranking equally in right of payment with all other senior unsecured indebtedness of the Company. See Note 7 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.
Leases. The Company's short-term and long-term operating lease obligations primarily relate to contracted drilling rigs, equipment and office facilities. See Note 10 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.
Derivative obligations. The Company's short-term and long-term derivative obligations represent net liabilities determined in accordance with master netting arrangements for commodity derivatives that were valued as of December 31, 2020. The Company's commodity derivative contracts are periodically measured and recorded at fair value and continue to be subject to market and credit risk. The ultimate liquidation value of the Company's commodity derivatives will be dependent upon actual future commodity prices, which may differ materially from the inputs used to determine the derivatives' fair values as of December 31, 2020. See Note 4 and Note 5 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" and "Item 7A. Quantitative and Qualitative Disclosures About Market Risk" for additional information.
Other liabilities. The Company's other liabilities represent current and noncurrent other liabilities that are comprised of 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 Note 9 and Note 11 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.
Book capitalization and current ratio. The Company's net book capitalization at December 31, 2020 was $13.4 billion, consisting of cash and cash equivalents of $1.4 billion, debt of $3.3 billion and equity of $11.6 billion. The Company's net debt to book capitalization increased to 14 percent at December 31, 2020 from 12 percent at December 31, 2019. The Company's ratio of current assets to current liabilities was 1.36:1 at December 31, 2020, as compared to 0.88:1 at December 31, 2019.
Debt ratings. The Company is rated as investment grade by three credit rating agencies. The Company's credit ratings are subject to regular reviews by the credit rating agencies. The Company believes that each of the rating agencies considers many factors in determining the Company's ratings, including: (i) production growth opportunities, (ii) liquidity, (iii) debt levels, (iv) asset composition and (v) 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 impact the Company's ability to obtain additional financing or the interest rate, fees and other terms associated with such additional financing.
Financing activities in connection with the Parsley Acquisition.
On the closing date of the Parsley Acquisition, Parsley merged into a newly formed wholly-owned subsidiary of the Company, and the subsidiaries of Parsley, including Jagged Peak Energy LLC ("Jagged Peak"), became indirect subsidiaries of the Company. In January 2021, the Company issued $750 million of 0.750% Senior Notes that will mature January 15, 2024,

59

Table of Contents
PIONEER NATURAL RESOURCES COMPANY
$750 million of 1.125% Senior Notes that will mature January 15, 2026 and $1 billion of 2.150% Senior Notes that will mature January 15, 2031 (the "January 2021 Senior Notes Offering"). The Company received proceeds, net of $18 million of issuance costs and discounts, of $2.5 billion. The senior notes are unsecured obligations ranking equally in right of payment with all other senior unsecured indebtedness of the Company.
The Company used the proceeds from the January 2021 Senior Notes Offering to (i) pay $1.6 billion to redeem Parsley's 5.250% Senior Notes due 2025, Parsley's 5.375% Senior Notes due 2025 and Jagged Peak's 5.875% Senior Notes due 2026, and (ii) pay $852 million to purchase a portion of the outstanding Parsley 5.625% Senior Notes due 2027 and 4.125% Senior Notes due 2028 pursuant to a cash tender offer. In connection with the tender offers, the Company also obtained the requisite consents from holders of Parsley's 5.625% Senior Notes due 2027 and 4.125% Senior Notes due 2028 to amend the indentures pursuant to which the notes were issued to, among other things, (i) eliminate substantially all of the restrictive covenants and related provisions and certain events of default contained in each indenture and (ii) shorten the minimum notice requirement for optional redemptions to three days. Following the completion of the tender offers, an aggregate principal amount of $179 million of Parsley's 5.625% Senior Notes due 2027 and $138 million of Parsley's 4.125% Senior Notes due 2028 remained outstanding. See Note 19 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.
Critical Accounting Estimates
The Company prepares its consolidated financial statements for inclusion in this Report in accordance with GAAP. See Note 2 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information. 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.
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 that 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.
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 proved 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, 2020, 2019 and 2018 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, 2020 is the current market value of the Company's estimated proved reserves. In accordance with SEC requirements, the Company based the 2020 Standardized Measure on a twelve month average of commodity prices on the first day of each month in 2020 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 2. Properties" and Unaudited Supplementary Information included in "Item 8. Financial Statements and Supplementary Data" for additional information.
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

60

Table of Contents
PIONEER NATURAL RESOURCES COMPANY
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, commodity 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 Note 4 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.
Impairment of unproved oil and gas properties. Management assesses unproved oil and gas properties for impairment on a project-by-project basis. Such assessments are affected by the results of exploration activities, commodity price outlooks, planned future property sales or the expiration of all or a portion of such projects.
Suspended wells. The Company suspends the costs of exploratory/extension 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/extension well as an asset in its consolidated balance sheets following the completion of drilling unless both of the following conditions are met:
The well has found a sufficient quantity of reserves to justify its completion as a producing well; and
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, transportation or processing facilities and/or getting partner approval to drill additional appraisal wells. These activities are ongoing and being pursued constantly. Consequently, the Company's assessment of suspended exploratory/extension well costs is continuous until a decision can be made that the well has found sufficient quantities of proved reserves to sanction the project or is determined to be noncommercial and is impaired. See Note 6 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.
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 or other property and equipment balance. See Note 9 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.
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 will be realized prior to their expiration. Pioneer monitors Company-specific, oil and gas industry and worldwide economic factors and based on that information, along with other data, 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.

Uncertain tax positions. 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. If all or a portion of the unrecognized tax benefits is sustained upon examination by the taxing authorities, the tax benefit will be recorded as a reduction to the Company's deferred tax liability and will affect the Company's effective tax rate in the period it is recorded. As of December 2020, the Company did not have any unrecognized tax benefits. See Note 17 of Notes to the Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.
Goodwill impairment. The Company reviews its goodwill for impairment at least annually. During the third quarter of 2020, the Company performed a qualitative assessment of goodwill to assess 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 whether it was necessary to record a noncash impairment charge. The Company determined that it was more likely than not that the Company's goodwill was not impaired. There is considerable judgment involved in estimating fair values, particularly in determining the valuation methods and the weighting to use for each method if multiple valuation methods are applied.
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 11 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.
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 (i) the Black-Scholes option pricing model to measure the fair value of stock options, (ii) the closing stock price on the day prior to the date of grant for the fair value of restricted stock awards, (iii) the closing stock price on the balance sheet date for restricted stock awards that are expected to be settled wholly or partially in cash on their vesting date and (iv) the Monte Carlo simulation method for the fair value of performance unit awards. See Note 8 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.
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 measures and records at fair value on a recurring basis include equity investments, deferred compensation plan assets, commodity derivative contracts and interest rate contracts. Other assets are not measured at fair value on an ongoing basis, but are subject to fair value adjustments in certain circumstances. The assets and liabilities that the Company measures and records at fair value on a nonrecurring basis include inventories, proved and unproved oil and gas properties, assets acquired and liabilities assumed in business combinations and other long-lived assets that are written down to fair value when they are determined to be impaired or held for sale. The Company also measures and discloses certain financial assets and liabilities at fair value, such as long-term debt and investments. The valuation methods used by the Company to measure the fair values of these assets and liabilities may 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 4 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.

PIONEER NATURAL RESOURCES COMPANY
ITEM 7A.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
In the normal course of business, the Company's financial position is routinely subject to a variety of risks, including market risks associated with changes in commodity prices, interest rate movements on outstanding debt and credit risks. These risks are mitigated through the Company's risk management program, which includes the use of derivative financial instruments and sales of purchased oil and gas. The following quantitative and qualitative information is provided about financial instruments to which the Company was a party as of December 31, 2020, and from which the Company may incur future gains or losses from changes in commodity prices or interest rates. The Company does not enter into any financial instruments, including derivatives, for speculative or trading purposes.
Interest rate risk. As of December 31, 2020, the Company had no variable rate debt outstanding under the Credit Facility and therefore no related exposure to interest rate risk. As of December 31, 2020, the Company had $3.3 billion of fixed rate long-term debt outstanding with an weighted average cash interest rate of 2.2 percent. Although changes in interest rates may affect the fair value of the Company's fixed rate long-term debt, any changes would not expose the Company to the risk of earnings or cash flow losses. The Company has no interest rate derivative instruments outstanding; however, it may enter into derivative instruments in the future to mitigate interest rate risk if the Company becomes subject to exposure to interest rate risk. See Note 4 and Note 7 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.
Commodity price risk. The Company's primary market risk exposure is tied to the price it receives from the sale of its oil, NGL and gas production. Realized pricing is volatile and is determined by market prices that fluctuate with changes in supply and demand for these products throughout the world. The price the Company receives for its production depends on many factors outside of the control of the Company, including differences in commodity pricing at the point of sale versus various index prices. Reducing the Company's exposure to price volatility helps secure funds to be used in its capital program and to pay contractual obligations and dividends. The Company mitigates its commodity price risk through the use of derivative financial instruments, sales of purchased oil and gas and marketing derivatives.
Derivative financial instruments. The Company's decision on the quantity and price at which it executes derivative contracts is based in part on its view of current and future market conditions. The Company may choose not to enter into derivative positions for expected production if the price environment for certain time periods is deemed to be unfavorable. Additionally, the Company may choose to liquidate existing derivative positions prior to the expiration of their contractual maturity in order to monetize gain positions for the purpose of funding its capital program, contractual obligations, dividends and share repurchases. While derivative positions limit the downside risk of adverse price movements, it also limits future revenues from upward price movements. The Company manages commodity price risk with the following types of derivative contracts:
Swaps. The Company receives a fixed price and pays a floating market price to the counterparty on a notional amount of sales volumes, thereby fixing the price for the commodity sold.
Collars. Collar contracts provide minimum ("floor" or "long put") and maximum ("ceiling") prices on a notional amount of sales volumes, thereby allowing some price participation if the relevant index price closes above the floor price but below the ceiling price.
Collar contracts with short put options. 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 long put-to-short put price differential.
Basis swaps. Basis swap contracts fix the basis differentials between the index price at which the Company sells its production and the index price used in swap or collar contracts.
Options. Selling individual call options can enhance the market price by the premium received or the premium received can be utilized to improve swap or collar contract prices. Purchased put options establish a minimum floor price (less any premiums paid) and allows participation in higher prices when prices close above the floor price.
The Company has entered into derivative contracts for a portion of its forecasted 2021 and 2022 production; consequently, if commodity prices decline, the Company could realize lower prices for volumes not protected by the Company's derivative activities and could see a reduction in derivative contract prices available for the volumes not protected in the future. As a result, the Company's internal cash flows will be negatively impacted by a reduction in commodity prices.

See Note 4 and Note 5 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for a description of the Company's open derivative positions and additional information.
Sales of purchased commodities. The Company enters into purchase transactions with third parties and separate sale transactions with third parties to diversify a portion of the Company's oil and gas sales to (i) Gulf Coast refineries, (ii) Gulf Coast and West Coast gas markets and (iii) international oil markets and to satisfy unused gas pipeline capacity commitments.
Marketing derivatives. The Company's marketing derivatives reflect two long-term marketing contracts that were entered in October 2019. Under the contract terms, beginning on January 1, 2021, the Company agreed to purchase and simultaneously sell 50 thousand barrels of oil per day at an oil terminal in Midland, Texas for a six-year term that ends on December 31, 2026. The price the Company pays to purchase the oil volumes under the purchase contract is based on a Midland WTI price and the price the Company receives for the oil volumes sold is a weighted average sales price ("WASP") that a non-affiliated counterparty receives for selling oil through their Gulf Coast storage and export facility at prices that are highly correlated with Brent oil prices during the same month of the purchase. Similar to sales of purchased commodities, marketing derivatives allow the Company to diversify a portion of its oil sales from its area of production to Gulf Coast and international markets.

Credit risk. The Company's primary concentration of credit risks are associated with the collection of receivables resulting from the sale of oil and gas production and purchased oil and gas, and the risk of a counterparty's failure to meet its obligations under derivative contracts with the Company.
The Company's commodities are sold to various purchasers who must be prequalified under the Company's credit risk policies and procedures. The Company monitors exposure to counterparties primarily by reviewing credit ratings, financial criteria and payment history. Where appropriate, the Company obtains assurances of payment, such as a guarantee by the parent company of the counterparty, a letter of credit or other credit support. Historically, the Company's credit losses on commodity receivables have not been material.
The Company uses credit and other financial criteria to evaluate the credit standing of, and to select, counterparties to its derivative instruments. Although the Company does not obtain collateral or otherwise secure the fair value of its derivative instruments, associated credit risk is mitigated by the Company's credit risk policies and procedures.
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 right of set off upon the occurrence of defined acts of default by either the Company or a counterparty to a derivative contract, 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 5 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Stockholders and the Board of Directors of Pioneer Natural Resources Company
Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheets of Pioneer Natural Resources Company (the Company) as of December 31, 2020 and 2019, the related consolidated statements of operations, equity and cash flows for each of the three years in the period ended December 31, 2020, and the related notes (collectively referred to as the "consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2020, in conformity with U.S. generally accepted accounting principles.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), and our report dated March 1, 2021 expressed an adverse opinion thereon.
Basis for Opinion
These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.
Critical Audit Matters
The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.
Depreciation, Depletion and Amortization of Proved Oil and Gas Properties
Description of the Matter
At December 31, 2020, the net book value of the Company's proved oil and gas properties was $13,863 million, and depreciation, depletion and amortization (DD&A) expense was $1,639 million for the year then ended. As described in Note 2, under the successful efforts method of accounting, capitalized costs of proved properties are depleted using the units-of-production method based on proved reserves, as estimated by the Company's engineers. Proved oil and gas reserve estimates are based on geological and engineering interpretation and judgment. Significant judgment is required by the Company's engineers in evaluating geological and engineering data when estimating proved oil and gas reserves. Estimating reserves also requires the selection of inputs, including oil and gas price assumptions, future operating and capital cost assumptions and tax rates by jurisdiction, among others. Because of the complexity involved in estimating oil and gas reserves, management used independent petroleum engineers to audit the estimates prepared by the Company's engineers as of December 31, 2020.

Auditing the Company's DD&A calculation is especially complex because of the use of the work of the Company's engineers and the independent petroleum engineers and the evaluation of management's determination of the inputs described above used by the engineers in estimating proved oil and gas reserves.

67

How We Addressed the Matter in Our Audit
We obtained an understanding, evaluated the design and tested the operating effectiveness of the Company's controls over its process to calculate DD&A, including management’s controls over the completeness and accuracy of the financial data provided to the engineers for use in estimating proved oil and gas reserves.
Our audit procedures included, among others, evaluating the professional qualifications and objectivity of the Company's engineers responsible for the preparation of the reserve estimates and the independent petroleum engineers used to audit the estimates. In addition, in assessing whether we can use the work of the engineers we evaluated the completeness and accuracy of the financial data and inputs described above used by the engineers in estimating proved oil and gas reserves by agreeing them to source documentation and we identified and evaluated corroborative and contrary evidence. For proved undeveloped reserves, we evaluated management's development plan for compliance with SEC requirements. We also tested the mathematical accuracy of the DD&A calculations, including comparing the proved oil and gas reserves amounts used to the Company’s reserve report.
Convertible Senior Notes
Description of the Matter
As discussed in Note 7 to the consolidated financial statements, in May 2020, the Company issued $1.3 billion convertible senior notes (the "Convertible Senior Notes"). Concurrent with the issuance of the Convertible Senior Notes, the Company entered into call transactions that are exercisable upon conversion of the Convertible Senior Notes (collectively with the Convertible Senior Notes referred to as the "Convertible Senior Notes Transactions"). The accounting for the Convertible Senior Notes Transactions was complex as it required assessment as to whether features in the Convertible Senior Notes required bifurcation and an evaluation of the appropriate classification of those features in the financial statements. Additionally, the Convertible Senior Notes Transactions were complex as valuation of the conversion feature in the Convertible Senior Notes involved estimation of the fair value of the liability component of the Convertible Senior Notes on a stand-alone basis.

Auditing management's evaluation of the Convertible Senior Notes Transactions involved addressing the complexity in assessing the components for separability and assessing valuation of the liability component on a stand-alone basis. The Company estimated the fair value of the liability component of the Convertible Senior Notes using a discounted cash flow model. This model utilized inputs such as contractual interest rate and repayment terms, risk-free interest rate, benchmark forward yield curves and the average term-yield on the Company's existing non-convertible debt. The fair value of the liability component is sensitive to changes in the discount rate. The Company also performed a detailed analysis of the terms of the Convertible Senior Notes Transactions to identify whether there were any embedded derivatives that required separate identification and valuation under applicable accounting guidance.
How We Addressed the Matter in Our Audit
We obtained an understanding, evaluated the design and tested the operating effectiveness of the Company's controls over its accounting for the Convertible Senior Notes Transactions, including its controls over the estimation of the fair value of the stand-alone liability component and evaluating the existence of embedded derivatives.
To test the initial accounting for the Convertible Senior Notes Transactions, our procedures included, among others, inspection of the agreements for the Convertible Senior Notes Transactions and assessing management’s application of the relevant accounting guidance. We also involved our valuation specialists to assist in our evaluation of the Company’s determination of the fair value of the liability component on a stand-alone basis, including testing the appropriateness of the methodology and the discount rate.

PIONEER NATURAL RESOURCES COMPANY
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
December 31, 2020, 2019 and 2018


NOTE 1. 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 that explores for, develops and produces oil, natural gas liquids ("NGLs") and gas in the Permian Basin in West Texas.
Impact of the COVID-19 Pandemic. A novel strain of the coronavirus ("COVID-19") surfaced in late 2019 and has spread around the world, including to the United States. In March 2020, the World Health Organization declared COVID-19 a pandemic, and the President of the United States declared the COVID-19 outbreak a national emergency. The COVID-19 pandemic has significantly affected the global economy, disrupted global supply chains and created significant volatility in the financial markets. In addition, the COVID-19 pandemic has resulted in travel restrictions, business closures and other restrictions that have disrupted the demand for oil throughout the world and when combined with pressures on the global supply-demand balance for oil and related products, resulted in significant volatility in oil prices beginning in late February 2020. The length of this demand disruption is unknown, and will ultimately depend on various factors beyond the Company's control, such as the duration and scope of the pandemic, the length and severity of the worldwide economic downturn, the ability of OPEC, Russia and other oil producing nations to manage the global oil supply, additional actions by businesses and governments in response to the pandemic, the speed and effectiveness of responses to combat the virus, including the effectiveness of the COVID-19 vaccines, and the time necessary to balance oil supply and demand. Additionally, there is significant uncertainty regarding the lasting impacts of the pandemic on global demand, as it cannot be predicted as to whether certain demand-reducing behaviors such as declines in business travel and changes in work-from-home practices will persist beyond the resolution of the pandemic. The length of this demand disruption is unknown, and there is significant uncertainty regarding the long-term impact of the effects of the COVID-19 pandemic to global oil demand, which has negatively impacted the Company's results of operations and led to a significant reduction in the Company's 2020 capital activities.
NOTE 2. 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. All material intercompany balances and transactions have been eliminated.
Correction of previously issued financial statements. During the Company's review of its marketing contracts during the fourth quarter of 2020, the Company identified two long-term marketing contracts that should have been accounted for as derivative contracts. The contracts were entered in October 2019, each with a January 1, 2021 contract commencement date and a December 31, 2026 contract termination date. In order to properly account for the contracts as derivatives, certain noncash revisions have been made to the 2019 consolidated financial statements. In addition, the unaudited consolidated financial statements for the first three quarters of 2020 were revised or restated accordingly.
In accordance with Staff Accounting Bulletin ("SAB") No. 99, Materiality, and SAB No. 108, Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements, the Company evaluated the misstatements and, based on an analysis of quantitative and qualitative factors, determined that the related impact was not material to the Company's 2019 annual consolidated financial statements or interim periods prior to September 30, 2020; however, the Company determined that the impact of the misstatement to its interim period ending September 30, 2020 was material. In accordance with Accounting Standards Codification 250, Accounting Changes and Error Corrections, the Company has corrected the misstatement for the year ended December 31, 2019 by revising the consolidated financial statements appearing herein. The net impact of these immaterial corrections to the Company's previously reported consolidated financial statements for the year ended December 31, 2019 is shown below. In addition, see Selected Quarterly Financial Results for revisions and restatements to the Company's previously issued unaudited interim consolidated financial statements that were impacted by this misstatement.

Use of estimates in the preparation of financial statements. Preparation of the Company's consolidated financial statements in conformity with generally accepted accounting principles in the United States ("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 is determined using estimates of proved oil and gas reserves. There are numerous uncertainties inherent in the estimation of quantities of proved reserves and in the projection of future rates of production and the timing of development expenditures. Similarly, evaluations for impairment of proved and unproved oil and gas properties are subject to numerous uncertainties including, among others, estimates of future recoverable reserves, commodity price outlooks and prevailing market rates of other sources of income and costs. Actual results could differ from the estimates and assumptions utilized.
Cash and cash equivalents. The Company's cash and cash equivalents include depository accounts held by banks and marketable securities (including commercial paper and time deposits) with original issuance maturities of 90 days or less.
Restricted cash. The Company's restricted cash includes funds held in escrow to cover future deficiency fee payments in connection with the Company's 2019 sale of its Eagle Ford assets and other remaining assets in South Texas (the "South Texas Divestiture"). Beginning in 2021, the required escrow balance declines and, to the extent there is any remaining balance after the payment of deficiency fees, the balance will become unrestricted and revert to the Company on March 31, 2023. Interest income related to restricted cash is recorded in interest and other income in the consolidated statements of operations.
Accounts receivable. 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. The

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
December 31, 2020, 2019 and 2018
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 historical collection experience, current and future economic and market conditions, the length of time that the accounts receivables have been outstanding and the financial condition of its purchasers. The Company's credit risk related to collecting accounts receivables is mitigated by using credit and other financial criteria to evaluate the credit standing of the entity obligated to make payment on the accounts receivable, and where appropriate, the Company obtains assurances of payment, such as a guarantee by the parent company of the counterparty letters of credit or other credit support.
The Company's allowance for doubtful accounts totaled $3 million and $2 million as of December 31, 2020 and 2019, respectively. On January 1, 2020, the Company adopted Accounting Standards Update ("ASU") 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments" ("ASU 2016-13") prospectively. This ASU replaced the incurred loss impairment model with an expected credit loss impairment model for financial instruments, including trade receivables. The amendment requires the Company to consider forward-looking information to estimate expected credit losses, resulting in earlier recognition of losses for receivables that are current or not yet due, which were not considered under the previous accounting guidance. As a result of adopting ASU 2016-13, the Company establishes allowances for bad debts equal to the estimable portions of accounts receivable for which failure to collect is expected to occur. The Company estimates uncollectible amounts for joint interest receivables based on the length of time that the accounts receivables have been outstanding, historical collection experience and current and future economic and market conditions. Allowances for doubtful accounts are recorded as reductions to the carrying values of the receivables included in the Company's consolidated balance sheets and are recorded in 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 maintenance materials and repair parts, water, chemicals and other operating supplies. The materials and supplies inventory is primarily acquired for use in future drilling and production operations or repair operations and is carried at the lower of cost or market, on a weighted average cost basis. Valuation allowances for materials and supplies inventories are recorded as reductions to the carrying values of the materials and supplies inventories included in the Company's consolidated balance sheets and are recorded in other expense in the consolidated statements of operations.
Commodity inventories are carried at the lower of cost or market, on a first-in, first-out basis. The Company's commodity inventories consist of oil, NGLs, gas and diesel volumes held in storage or as linefill in pipelines. Any valuation allowances of commodity inventories are recorded as reductions to the carrying values of the commodity inventories included in the Company's consolidated balance sheets and as charges to other expense in the consolidated statements of operations.
The components of inventories are as follows:
As of December 31,
2020 2019
(in millions)
Materials and supplies (a) $ 75  $ 75 
Commodities 149  130 
Total inventories $ 224  $ 205 
____________________
(a)As of December 31, 2020 and 2019, the Company's materials and supplies inventories were net of valuation allowances of $1 million and $2 million, respectively.
Investment in affiliate. In December 2018, the Company completed the sale of its pressure pumping assets to ProPetro Holding Corp. ("ProPetro") in exchange for cash and 16.6 million shares of ProPetro's common stock, representing an ownership interest in ProPetro of 16 percent. Additionally, in October 2019, Phillip A. Gobe, a nonemployee member of the Company's board of directors, was appointed by the board of directors of ProPetro to serve as its Executive Chairman, and in March 2020 he was appointed as Chief Executive Officer and Chairman of the Board of Directors. Mark S. Berg, the Company's Executive Vice President, Corporate Operations, serves as a member of the ProPetro board of directors under the Company's right acquired upon the sale of its pressure pumping assets to designate a director to the board of directors of ProPetro so long as the Company owns five percent or more of ProPetro's outstanding common stock. Based on the Company's ownership in ProPetro and representation on the ProPetro board of directors, ProPetro is considered an affiliate and deemed to

PIONEER NATURAL RESOURCES COMPANY
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

be a related party. The Company uses the fair value option to account for its equity method investment in ProPetro with any changes in fair value recorded in interest and other income in the consolidated statement of operations. The carrying value of the Company's investment in ProPetro is included in investment in affiliate in the consolidated balance sheets. See Note 4 and Note 12 for additional information.
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.
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 and (ii) the Company is making sufficient progress assessing the reserves and the economic and operating viability of the project. The Company's exploratory wells include extension wells which extend the limits of a known reservoir.
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 6 for additional information.
As of December 31, 2020, the Company owns interests in 11 gas processing plants, including the related gathering systems. The Company's ownership interests in the gas processing plants 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. The operator's of the plants process the Company's and third-party gas volumes for a fee. The Company's share of revenues and expenses derived from volumes processed through the plants and treating facilities are reported as components of oil and gas production costs. Revenues generated from the processing plants and treating facilities for the years ended December 31, 2020, 2019 and 2018 were $178 million, $140 million and $124 million, respectively. Expenses attributable to the processing plants and treating facilities for the same respective periods were $76 million, $65 million and $75 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 recognized.
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 recorded until an entire amortization base is sold. However, gain or loss is recorded 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, including vertical integrated services that are used in the development of the assets, is less than the carrying amount of the assets, including the carrying value of vertical integrated services assets. In these circumstances, the Company recognizes an impairment charge for the amount by which the carrying amount of the assets exceeds the estimated fair value of the assets. Impairment charges for proved oil and gas properties are recorded in impairment of oil and gas properties in the consolidated statements of operations. See Note 4 for additional information.

78

PIONEER NATURAL RESOURCES COMPANY
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
December 31, 2020, 2019 and 2018
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 property sales or expiration 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 charge at that time. Impairment charges for unproved oil and gas properties are recorded in exploration and abandonments in the consolidated statements of operations.
Goodwill. Goodwill is assessed for impairment whenever it is more likely than not that events or circumstances indicate the carrying value of a reporting unit exceeds its fair value, but no less often than annually. An impairment charge is recorded for the amount by which the carrying amount exceeds the fair value of a reporting unit in the period it is determined to be impaired.
The Company performed its annual qualitative assessment of goodwill during the third quarter of 2020 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. Based on the results of the assessment, the Company determined it was not likely that the carrying value of the Company's reporting unit exceeded its fair value. See Note 4 for additional information.
Other property and equipment, net. Other property and equipment is recorded at cost. The carrying values of other property and equipment, net of accumulated depreciation of $463 million and $382 million as of December 31, 2020 and 2019, respectively, are as follows:
As of December 31,
2020 2019
(in millions)
Land and buildings (a) $ 849  $ 877 
Water infrastructure (b) 414  404

Furniture and fixtures 27  28 
Sand reserves (e) 15  16 
Total other property and equipment, net $ 1,584  $ 1,632 
____________________
(a)Includes land, buildings, any related improvements to land and buildings, and a finance lease entered into by the Company for its corporate headquarters in Irving, Texas. See Note 10 for additional information.
(b)Includes costs for pipeline infrastructure and water supply wells.
(c)Includes capitalized costs and capitalized interest on other property and equipment not yet placed in service.
(d)Includes vehicles and well servicing equipment, including pulling units, fracture stimulation tanks, water transport trucks, hot oilers, construction equipment and fishing tools, that are used on Company-operated properties.
(e)Includes sand mines and unproved leaseholds that provide the Company with proppant for use in the fracture stimulation of oil and gas wells.
Other property and equipment is depreciated over its estimated useful life on a straight-line basis. Buildings are generally depreciated over 20 to 39 years. Water infrastructure is generally depreciated over three to 50 years. Equipment, vehicles, furniture and fixtures and information technology assets are generally depreciated over three to 10 years. Sand reserves are depleted on a units-of-production basis.
The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If such assets are considered to be impaired, the impairment to be recorded is measured by the amount by which the carrying amount of the asset exceeds its estimated fair value. The estimated fair value is determined using either a discounted future cash flow model or another appropriate fair value method.
Leases. The Company enters into leases for drilling rigs, storage tanks, equipment and buildings and recognizes lease expense on a straight-line basis over the lease term. Lease right-of-use assets and liabilities are initially recorded on the lease commencement date based on the present value of lease payments over the lease term. As most of the Company's lease contracts do not provide an implicit discount rate, the Company uses its incremental borrowing rate, which is determined based

79

PIONEER NATURAL RESOURCES COMPANY
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
December 31, 2020, 2019 and 2018
on information available at the commencement date of a lease. Leases may include renewal, purchase or termination options that can extend or shorten the term of the lease. The exercise of those options is at the Company's sole discretion and is evaluated at inception and throughout the contract to determine if a modification of the lease term is required. Leases with an initial term of 12 months or less are not recorded as a lease right-of-use asset and liability. See Note 10 for additional information.
Asset retirement obligations. The Company records a liability for the fair value of an asset retirement obligation in the period in which the associated asset is acquired or placed into service, 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 recorded when incurred and when fair value can be reasonably estimated.
The Company includes the current and noncurrent portions of asset retirement obligations in other current liabilities and other liabilities, respectively, in the consolidated balance sheets and expenditures are included as cash used in operating activities in the consolidated statements of cash flows. See Note 9 for additional information.
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.
Revenue recognition. On January 1, 2018, the Company adopted Accounting Standards Codification ("ASC") 606, "Revenue from Contracts with Customers," ("ASC 606") using the modified retrospective transition method. The adoption did not require an adjustment to retained earnings as there was no material change to the timing or pattern of revenue recognition due to the adoption of ASC 606. The Company recognizes revenue when control of the promised goods or services is transferred to customers at an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services.
Oil sales. Sales under the Company's oil contracts are generally considered performed when the Company sells oil production at the wellhead and receives an agreed-upon index price, net of any price differentials. The Company recognizes the sales revenue when (i) control/custody transfers to the purchaser at the wellhead and (ii) the net price is fixed and determinable.
NGL and gas sales. Under the majority of the Company's gas processing contracts, gas is delivered to a midstream processing entity and the Company elects to take residue gas and NGLs in-kind at the tailgate. The Company recognizes revenue when the products are delivered (custody transfer) to the ultimate third-party purchaser at a contractually agreed-upon delivery point at a specified index price.
Sales of purchased commodities. The Company enters into purchase transactions with third parties and separate sale transactions with third parties to diversify a portion of the Company's oil and gas sales to (i) Gulf Coast refineries, (ii) Gulf Coast and West Coast gas markets and (iii) international oil markets and to satisfy unused gas pipeline capacity commitments. Revenues and expenses from these transactions are generally presented on a gross basis as the Company acts as a principal in the transaction by assuming both the risks and rewards of ownership, including credit risk, of the commodities purchased and the responsibility to deliver the commodities sold. In conjunction with the Company's downstream sales, the Company also enters into pipeline capacity commitments in order to secure available oil, NGL and gas transportation capacity from the Company's areas of production to downstream sales points. The transportation costs associated with these transactions are included in purchased commodities expense.
See Note 14 for additional information.
Derivatives. All of the Company's derivatives are accounted for as non-hedge derivatives and are recorded at estimated fair value in the consolidated balance sheets. All changes in the fair values of its derivative contracts are recorded as gains or losses in the earnings of the periods in which they occur. 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. 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 credit-adjusted risk-free rate

80

PIONEER NATURAL RESOURCES COMPANY
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
December 31, 2020, 2019 and 2018
curve. 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.
The Company's credit risk related to derivatives is a counterparty's failure to perform under derivative contracts owed to the Company. The Company uses credit and other financial criteria to evaluate the credit standing of, and to select, counterparties to its derivative instruments. Although the Company does not obtain collateral or otherwise secure the fair value of its derivative instruments, associated credit risk is mitigated by the Company's credit risk policies and procedures.
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 5 for additional information.
Income taxes. The provision for income taxes is determined using the asset and liability approach of accounting for income taxes. Under this approach, deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes and net operating loss and tax credit carryforwards. The amount of deferred taxes on these temporary differences is determined using the tax rates that are expected to apply to the period when the asset is realized or the liability is settled, as applicable, based on tax rates and laws in the respective tax jurisdiction enacted as of the balance sheet date.
The Company reviews its deferred tax assets for recoverability and establishes a valuation allowance based on projected future taxable income, applicable tax strategies and the expected timing of the reversals of existing temporary differences. A valuation allowance is provided when it is more likely than not (likelihood of greater than 50 percent) that some portion or all of the deferred tax assets will not be realized.
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. If all or a portion of the unrecognized tax benefit is sustained upon examination by the taxing authorities, the tax benefit will be recognized as a reduction to the Company's deferred tax liability and will affect the Company's effective tax rate in the period it is recognized. See Note 17 for additional information.
The Company records any tax-related interest charges as interest expense and any tax-related penalties as other expense in the consolidated statements of operations.
Stock-based compensation. Stock-based compensation expense for restricted stock, restricted stock units and performance units expected to be settled in the Company's common stock ("Equity Awards") is measured at the grant date or modification date, as applicable, using the fair value of the award, and is recorded, net of estimated forfeitures, on a straight line basis over the requisite service period of the respective award. The fair value of Equity Awards, except performance unit awards, is determined on the grant date or modification date, as applicable, using the prior day's closing stock price. The fair value of performance unit awards is determined using the Monte Carlo simulation model.
Equity Awards are net settled by withholding shares of the Company's common stock to satisfy income tax withholding payments due upon vesting. Remaining vested shares are remitted to individual employee brokerage accounts. Shares to be delivered upon vesting of Equity Awards are made available from authorized, but unissued shares or shares held as treasury stock.
Restricted stock awards expected to be settled in cash on their vesting dates, rather than in common stock ("Liability Awards"), are included in accounts payable – due to affiliates in the consolidated balance sheets. The fair value of Liability Awards on the grant date is determined using the prior day's closing stock price. The Company recognizes the value of Liability Awards on a straight line basis over the requisite service period of the award. Liability Awards are marked to fair value as of each balance sheet date using the closing stock price on the balance sheet date. Changes in the fair value of Liability Awards are recorded as increases or decreases to stock-based compensation expense.
Equity Awards and Liability Awards participate in dividends during vesting periods and generally vest over three years.
Segments. Based upon how the Company is organized and managed, the Company has one reportable operating segment, which is oil and gas development, exploration and production. The Company considers its vertical integration services

and sales of purchased commodities as ancillary to its oil and gas development, 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.
New accounting pronouncements. In August 2020, the FASB issued ASU 2020-06, "Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity's Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity's Own Equity" ("ASU 2020-06"). ASU 2020-06 simplifies the accounting for certain convertible instruments by removing the separation models for convertible debt with a cash conversion feature or convertible instruments with a beneficial conversion feature. As a result, more convertible debt instruments will be reported as a single liability instrument with no separate accounting for embedded conversion features. Additionally, this ASU amends the diluted earnings per share calculation for convertible instruments by requiring the use of the if-converted method. The treasury stock method will no longer be available. Entities may adopt this ASU using either a full or modified retrospective approach, and it is effective for interim and annual reporting periods beginning after December 15, 2021. Early adoption is permitted for interim and annual reporting periods beginning after December 15, 2020. This ASU is applicable to the Company's 0.25% convertible senior notes due 2025.
The Company plans to early adopt ASU 2020-06 on January 1, 2021. Upon issuance of the Company's 0.25% convertible senior note due 2025, the Company bifurcated the debt and equity components of the note to long-term debt and additional paid-in capital in the accompanying consolidated balance sheets respectively. Upon adoption of ASU 2020-06, the Company expects to reclassify the unamortized discount and fees on the convertible senior notes of $202 million from additional paid-in capital to long-term debt, which is expected to result in a reduction in the interest expense recognized over the remaining term of the convertible senior notes. See Note 7 for additional information.
NOTE 3. Acquisitions, Divestitures, Decommissioning and Restructuring Activities
Acquisitions. During 2020, 2019 and 2018, the Company spent a total of $14 million, $28 million and $65 million, respectively, to acquire primarily undeveloped acreage for future exploitation and exploration activities in the Spraberry/Wolfcamp field of the Permian Basin.
Divestitures. The Company's significant divestitures to unaffiliated third parties (except for the sale of the Company's pressure pumping assets that were sold to a related party) are as follows:
In May 2020, the Company completed the sale of certain vertical wells and approximately 1,500 undeveloped acres in Upton County of the Permian Basin for net cash proceeds of $6 million. The Company recorded a gain of $6 million associated with the sale.
In December 2019, the Company completed the sale of certain vertical and horizontal wells and approximately 4,500 undeveloped acres in Glasscock County of the Permian Basin for net cash proceeds of $64 million. The Company recorded a gain of $10 million associated with the sale.
In July 2019, the Company completed the sale of certain vertical wells and approximately 1,400 undeveloped acres in Martin County of the Permian Basin to for net cash proceeds of $27 million. The Company recorded a gain of $26 million associated with the sale.
In June 2019, the Company completed the sale of certain vertical wells and approximately 1,900 undeveloped acres in Martin County of the Permian Basin to for net cash proceeds of $38 million. The Company recorded a gain of $31 million associated with the sale.
In May 2019, the Company completed the sale of its Eagle Ford assets and other remaining assets in South Texas (the "South Texas Divestiture") in exchange for total consideration having an estimated fair value of $210 million. The fair value of the consideration included (i) net cash proceeds of $2 million, (ii) $136 million in contingent consideration and (iii) a $72 million receivable associated with estimated deficiency fees to be paid by the buyer. The Company recorded a loss of $525 million associated with the sale.
Contingent Consideration. Per the terms of the South Texas Divestiture, the Company was entitled to receive contingent consideration based on future annual oil and NGL prices during each of the five years from 2020 to 2024. The Company revalued the contingent consideration using an option pricing model each reporting period prior to the settlement of the contingent consideration in July 2020, at which time, the Company received cash proceeds of

82

PIONEER NATURAL RESOURCES COMPANY
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
December 31, 2020, 2019 and 2018
$49 million from the buyer to fully satisfy the contingent consideration. The Company recorded a noncash loss of $42 million to interest and other income during the year ended December 31, 2020 associated with the settlement. See Note 4, Note 5 and Note 15 for additional information.
Deficiency Fee Obligation. The Company transferred its long-term midstream agreements and associated minimum volume commitments ("MVC") to the buyer. However, the Company retained the obligation to pay 100 percent of any deficiency fees associated with the MVC from January 2019 through July 2022. The Company determines the fair value of the deficiency fee obligation using a probability weighted discounted cash flow model. The deficiency fee obligation is included in current or noncurrent liabilities in the consolidated balance sheets, based on the estimated timing of payments. During the year ended December 31, 2020, the Company recorded a charge of $84 million in other expense in the consolidated statements of operations, to increase the Company's forecasted deficiency fee payments as a result of a reduction in planned drilling activities by the buyer. The estimated remaining deficiency fee obligation was $333 million as of December 31, 2020. See Note 4 and Note 16 for additional information.
Deficiency Fee Receivable. The buyer is required to reimburse the Company for 18 percent of the deficiency fees paid under the transferred midstream agreements from January 2019 through July 2022. Such reimbursement will be paid by the buyer in installments beginning in 2023 through 2025. The Company determines the fair value of the deficiency fee receivable using a credit risk-adjusted valuation model. During the year ended December 31, 2020, the Company recorded an increase to the Company's long-term deficiency fee receivable of $4 million in other expense in the consolidated statements of operations, to reflect the buyer's share of 2020 deficiency fees which were greater than originally forecasted as of the date of the sale. The deficiency fee receivable is included in noncurrent other assets in the consolidated balance sheets. See Note 4 and Note 11 for additional information.
Restricted Cash. As a condition of the sale, the Company deposited $75 million into an escrow account to be used to fund future MVC payments. Beginning in 2021, the required escrow balance will decline to $50 million. To the extent that there is any remaining balance after the payment of deficiency fees, the balance will become unrestricted and revert to the Company on March 31, 2023. The escrow account balance is included in restricted cash in the consolidated balance sheets.
In December 2018, the Company completed the sale of its pressure pumping assets to ProPetro in exchange for total consideration of $282 million, comprised of 16.6 million shares of ProPetro's common stock, which was delivered as of the date of the sale with a fair value of $172 million, and $110 million in cash, which was received during the first quarter of 2019. During 2018, the Company recorded a gain of $30 million, employee-related charges of $19 million, contract termination charges of $13 million and other divestiture-related charges of $6 million associated with the sale. During 2019, the Company reduced the gain associated with the sale by $10 million and recorded additional employee-related charges of $1 million. See Note 12 for additional information.
In December 2018, the Company completed the sale of approximately 2,900 net acres in the Sinor Nest (Lower Wilcox) oil field in South Texas for net cash proceeds of $105 million. The Company recorded a gain of $54 million associated with the sale.
In August 2018, the Company completed the sale of its assets in the West Panhandle gas and liquids field for net cash proceeds of $170 million. The Company recorded a gain of $127 million and employee-related charges of $7 million associated with the sale.
In July 2018, the Company completed the sale of its gas field assets in the Raton Basin (the "Raton Basin Sale") for net cash proceeds of $54 million. The Company recorded a noncash impairment charge of $77 million in June 2018 to reduce the carrying value of its Raton Basin assets to their estimated fair value less costs to sell as the assets were considered held for sale. The Company recorded a gain of $2 million, other divestiture-related charges of $117 million, including $111 million of deficiency charges related to certain firm transportation contracts retained by the Company, and employee-related charges of $6 million associated with the sale.
In April 2018, the Company completed the sale of approximately 10,200 net acres in the West Eagle Ford Shale gas and liquids field for net cash proceeds of $100 million. The Company recorded a gain of $75 million associated with the sale.

The Company sold other proved and unproved properties, inventory and other property and equipment and recorded net gains of $3 million and $1 million during 2020 and 2018, respectively, and a net loss of $9 million during 2019.
Decommissioning. In November 2018, the Company announced plans to close its sand mine located in Brady, Texas and transition its proppant supply requirements to West Texas sand sources.
During 2019, the Company recorded $23 million of accelerated depreciation, $13 million of inventory and other property and equipment impairment charges and $12 million of sand mine closure-related costs.
During 2018, the Company recorded $443 million of accelerated depreciation and $7 million of employee-related charges associated with the closure.
Restructuring. During the third quarter of 2020, the Company announced a corporate restructuring to reduce its staffing levels to correspond with a planned reduction in future activity levels (the "2020 Corporate Restructuring"). The restructuring resulted in approximately 300 employees being involuntarily separated from the Company in October 2020. The Company recorded $78 million of employee-related charges, including $5 million of noncash stock-based compensation expense related to the accelerated vesting of certain equity awards, in other expense in the consolidated statements of operations during the year ended December 31, 2020. See Note 8 and Note 16 for additional information.
In June 2020, the Company implemented changes to its well services business, including a staffing reduction of approximately 50 employees. The changes were made to more closely align the well services cost structure and headcount with the Company's reduction in expected activity levels (the "2020 Well Services Restructuring"). The Company recorded $1 million of employee-related charges in other expense in the consolidated statements of operations during the year ended December 31, 2020 related to the staffing reductions in its well services business. See Note 16 for additional information.
During 2019, the Company implemented a corporate restructuring program to align its cost structure with the needs of a Permian Basin-focused company (the "2019 Corporate Restructuring Program"). The restructuring occurred in three phases as follows:
In March 2019, the Company made certain changes to its leadership and organizational structure, which included the early retirement and departure of certain officers of the Company.
In April 2019, the Company adopted a voluntary separation program ("VSP") for certain eligible employees, and
In May 2019, the Company implemented an involuntary separation program ("ISP").
During 2019, the Company recorded $159 million of employee-related charges, including $26 million of noncash stock-based compensation expense related to the accelerated vesting of certain equity awards, associated with the 2019 Corporate Restructuring Program. See Note 8 and Note 16 for additional information.
Employee-related costs are primarily recorded in other expense in the consolidated statements of operations. Obligations associated with employee-related charges are included in accounts payable - due to affiliates in the consolidated balance sheets.
The changes in the Company's employee-related obligations associated with its restructuring programs and asset divestitures are as follows:

NOTE 4. Fair Value Measurements
The Company determines fair value based on the price that would be received from selling an asset or 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 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 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, typically reflecting management's estimate of assumptions that market participants would use in pricing the asset or liability. The fair values are therefore determined using model-based techniques, including discounted cash flow models.
Assets and liabilities measured at fair value on a recurring basis. Assets and liabilities measured at fair value on a recurring basis are as follows:

Commodity price derivatives. The Company's commodity derivatives primarily represent oil, NGL and gas swap contracts, collar contracts, collar contracts with short puts and basis swap contracts. The asset and liability measurements for the Company's commodity derivative contracts are determined using Level 2 inputs. The Company utilizes discounted cash flow and option-pricing models for valuing its commodity price derivatives.
The asset and liability values attributable to the Company's commodity price derivatives were determined based on inputs that 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 contracts and collar contracts with short puts, which is based on active and independent market-quoted volatility factors.
Marketing derivatives. The Company's marketing derivatives reflect two long-term marketing contracts that were entered in October 2019. Under the contract terms, beginning on January 1, 2021, the Company agreed to purchase and simultaneously sell 50 thousand barrels of oil per day at an oil terminal in Midland, Texas for a six-year term that ends on December 31, 2026. The price the Company pays to purchase the oil volumes under the purchase contract is based on a Midland WTI price and the price the Company receives for the oil volumes sold is a weighted average sales price ("WASP") that the non-affiliated counterparty receives for selling oil through their Gulf Coast storage and export facility at prices that are highly correlated with Brent oil prices during the same month of the purchase. Based on the form of the marketing contracts, the Company determined that the marketing contracts should be accounted for as derivative instruments not designated as hedges. The asset and liability measurements for the Company's marketing derivative contracts are determined using both Level 2 and 3 inputs. The Company utilizes a discounted cash flow model for valuing its marketing derivatives.
The asset and liability values attributable to the Company's marketing derivative were determined based on Level 2 inputs that 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) stated contractual rates. The Level 3 inputs attributable to the Company's marketing derivatives include the historical monthly differential between Brent oil prices and the corresponding WASP of the counterparty to the marketing derivatives ("WASP Differential Deduction") and, to a lesser extent, an estimated annual cost inflation rate. The average WASP Differential Deduction used in the fair value determination as of December 31, 2020 and 2019 was $1.91 per barrel and $1.72 per barrel, respectively. The WASP Differential Deduction and the estimated annual cost inflation rate reflects management's best estimate of future results utilizing historical performance (excluding April 2020 and May 2020 for the average WASP Differential Deduction that were anomalously impacted by COVID-19), but these estimates are not observable inputs by a market participant and contain a high degree of uncertainty. The Company could experience significant mark-to-market fluctuations in the fair value of its marketing derivatives based on changes in the WASP Differential Deduction if it deviates from historical levels. For example, a 10 percent increase or decrease in the WASP Differential Deduction would impact the fair value of the Company's marketing derivatives recorded by approximately $20 million as of December 31, 2020.

Deferred compensation plan assets. The Company's deferred compensation plan assets include investments in equity and mutual fund securities that are actively traded on major exchanges. The fair value of these investments is determined using Level 1 inputs based on observable prices on major exchanges.
Investment in affiliate. The Company elected the fair value option for measuring its equity method investment in ProPetro. The fair value of its investment in ProPetro is determined using Level 1 inputs based on observable prices on a major exchange. See Note 12 and Note 15 for additional information.
Contingent consideration. Per the terms of the South Texas Divestiture, the Company was entitled to receive contingent consideration based on future annual oil and NGL prices during each of the five years from 2020 to 2024. The Company revalued the contingent consideration using an option pricing model each reporting period prior to the settlement of the contingent consideration in July 2020, at which time, the Company received cash proceeds of $49 million from the buyer to fully satisfy the contingent consideration. The Company recorded a noncash loss of $42 million to interest and other income during the year ended December 31, 2020 associated with the settlement. During 2019, the Company recorded a noncash loss of $45 million to interest and other income associated with adjusting the contingent consideration to fair value. The fair value of the contingent consideration was determined using Level 2 inputs based on an option pricing model using quoted future commodity prices from active markets, implied volatility factors and counterparty credit risk assessments. See Note 3 and Note 5 and Note 15 for additional information.
Assets and liabilities measured at fair value on a nonrecurring basis. Certain assets and liabilities are measured at fair value on a nonrecurring basis. These assets and liabilities are not measured at fair value on an ongoing basis and are subject to fair value adjustments in certain circumstances. These assets and liabilities can include inventory, proved and unproved oil and gas properties and other long-lived assets that are written down to fair value when they are impaired or held for sale.
Convertible Notes. In May 2020, the Company issued $1.3 billion principal amount of 0.25% convertible senior notes due 2025 ("Convertible Notes"). The Company bifurcated the Convertible Notes into debt and equity components at issuance. The value assigned to the debt component of $1.1 billion was the estimated fair value, as of the issuance date, of an equivalent senior note without the conversion feature. The difference between the cash proceeds and the estimated fair value, representing the value assigned to the equity component of $234 million was recorded as a debt discount. Through December 31, 2020, the Company had amortized $28 million of the initially recorded debt discount to interest expense. The Company measured the debt component at fair value by utilizing a discounted cash flow model. This model utilized observable inputs such as the contractual interest rate and repayment terms, the risk-free interest rate, benchmark forward yield curves and the average term-yield on the Company's existing non-convertible debt. See Note 7 for additional information.
Other assets. During the year ended December 31, 2019, the Company impaired the remaining $13 million of inventory and other property and equipment related to the decommissioning of the Company's Brady, Texas sand mine, as these assets had no remaining future economic value. In addition, the Company recognized a $16 million impairment charge related to pressure pumping assets that had no future benefit to the Company. See Note 16 for additional information.
South Texas Divestiture. During May 2019, the Company recorded the MVC obligation and related deficiency fee receivable in conjunction with the South Texas Divestiture. The fair value of the deficiency fee obligation and deficiency fee receivable was determined using Level 3 inputs based on a probability-weighted forecast that considers historical results, market conditions and various development plans to arrive at the estimated present value of the deficiency payments and corresponding receipts. Changes to the Company's forecasted deficiency fee obligation, as a result of the expected impact of the COVID-19 pandemic on the buyer's ability to drill economic wells, resulted in the Company recording a charge of $84 million to other expense in the consolidated statements of operations during the year ended December 31, 2020. In addition, the Company recorded an increase to the deficiency fee receivable of $4 million in other expense in the consolidated statements of operations to reflect an increase to the buyer's share of 2020 deficiency fees. The Company will not increase the estimated deficiency fee receivable associated with 2021 and 2022 forecasted deficiencies until they are realizable. The present value of the future cash payments and expected cash receipts were determined using a 3.6 percent and 3.2 percent discount rate, respectively, based on the estimated timing of future payments and receipts and the Company's counterparty credit risk assessments. See Note 3, Note 11 and Note 16 for additional information.
Sale of Raton Basin assets. In June 2018, the Company completed the Raton Basin Sale and recorded deficiency fee obligations related to certain firm transportation contracts retained by the Company of $111 million to other expense in the consolidated statements of operations. The fair value of these contracts was determined using Level 2 inputs, including an

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
December 31, 2020, 2019 and 2018
annual discount rate of 4.4 percent, to discount the expected future cash flows. See Note 3, Note 11 and Note 16 for additional information.
Proved oil and gas properties. The Company performs assessments of its proved oil and gas properties, which are 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, including cash flows from vertically integrated services that are used in the development of the assets, is less than the carrying amount of the assets, including the carrying value of the vertically integrated services. In these circumstances, the Company recognizes an impairment charge for the amount by which the carrying amount of the assets exceeds the estimated fair value of the assets.
Based on management's commodity price outlooks as of December 31, 2020, which represent longer-term commodity price outlooks that are developed based on third party future commodity price estimates as of a measurement date ("Management's Price Outlooks"), the Company determined events and circumstances did not indicate that the carrying value of the Company's proved properties were not recoverable.
Goodwill. Goodwill is assessed for impairment whenever it is more likely than not that events or circumstances indicate the carrying value of a reporting unit exceeds its fair value, but no less often than annually. An impairment charge is recorded for the amount by which the carrying amount exceeds the fair value of a reporting unit in the period it is determined to be impaired.
Based on the Company's annual assessment of the fair value of goodwill as of July 1, 2020, the Company determined that its goodwill was not impaired. As of December 31, 2020, there were no material changes in events or circumstances that would warrant a reassessment for impairment.
There is significant uncertainty surrounding the long-term impact to global oil demand due to the effects of the COVID-19 pandemic. These conditions negatively impacted the Company's 2020 capital activities and production levels and could negatively impact the Company's 2021 forecasted capital activities and production levels. It is reasonably possible that the carrying value of the Company's proved oil and gas properties or goodwill could exceed their estimated fair value potentially resulting in the need to impair their carrying values in the future. If incurred, an impairment of the Company's proved oil and gas properties or goodwill could have a material adverse effect on the Company's results of operation.
Financial instruments not carried at fair value. Carrying values and fair values of financial instruments that are not carried at fair value in the consolidated balance sheets are as follows:

The Company has other financial instruments consisting primarily of receivables, payables and other current assets and liabilities that approximate fair value due to the nature of the instrument and their relatively short maturities. Non-financial assets and liabilities initially measured at fair value include assets acquired and liabilities assumed in a business combination, goodwill and asset retirement obligations.
NOTE 5. Derivative Financial Instruments
The Company primarily utilizes commodity swap contracts, collar contracts, collar contracts with short puts and basis swap contracts 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) support the payment of contractual obligations and dividends.
Oil production derivatives. The Company sells its oil production at the lease and the sales contracts governing such oil production are tied directly to, or are correlated with, New York Mercantile Exchange ("NYMEX") West Texas Intermediate ("WTI") oil prices. The Company also enters into pipeline capacity commitments in order to secure available oil, NGL and gas transportation capacity from the Company's areas of production. The Company also enters into purchase transactions with third parties and separate sale transactions with third parties to diversify a portion of the Company's oil sales to Gulf Coast refineries or international export markets at prices that are highly correlated with Brent oil prices. As a result, the Company will generally use Brent derivative contracts to manage future oil price volatility.

NGL production derivatives. All material physical sales contracts governing the Company's NGL production are tied directly or indirectly to Mont Belvieu, Texas NGL component product prices. The Company uses derivative contracts to manage the NGL component product price volatility. As of December 31, 2020, the Company did not have any NGL derivative contracts outstanding.
Gas production derivatives. 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. To diversify the gas prices it receives to international market prices, the Company sells a portion of its gas production at Dutch Title Transfer Facility ("Dutch TTF") prices. 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.

Marketing derivatives. The Company's marketing derivatives reflect two long-term marketing contracts that were entered in October 2019. Under the contract terms, beginning on January 1, 2021, the Company agreed to purchase and simultaneously sell 50 thousand barrels of oil per day at an oil terminal in Midland, Texas for a six-year term that ends on December 31, 2026. The price the Company pays to purchase the oil volumes under the purchase contract is based on a Midland WTI price and the price the Company receives for the oil volumes sold is a WASP that a non-affiliated counterparty receives for selling oil through their Gulf Coast storage and export facility at prices that are highly correlated with Brent oil prices during the same month of the purchase. Based on the form of the marketing contracts, the Company determined that the marketing contracts should be accounted for as derivative instruments.
Contingent consideration. The Company's right to receive contingent consideration in conjunction with the South Texas Divestiture was determined to be a derivative financial instrument that is not designated as a hedging instrument. Prior to its settlement in July 2020, the contingent consideration was based on forecasted oil and NGL prices during each of the five years from 2020 to 2024. See Note 3 and Note 4 and Note 15 for additional information.

Credit facility. The Company maintains a revolving corporate credit facility (the "Credit Facility") with a syndicate of financial institutions (the "Syndicate"). As of December 31, 2020, the Credit Facility had aggregate loan commitments of $1.5 billion, a maturity date of October 2023 and the Company had no outstanding borrowings under the Credit Facility and was in compliance with its debt covenants.
Borrowings under the Credit Facility may be in the form of revolving loans or swing line loans. Revolving loans represent loans made ratably by the Syndicate in accordance with their respective commitments under the Credit Facility and 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 0.25 percent based upon the Company's debt rating or (b) a base Eurodollar rate, plus a margin (the "Applicable Margin"), which is currently 1.25 percent and is also determined by the Company's debt rating. Swing line loans represent loans made by a subset of the lenders in the Syndicate and may not exceed $150 million. 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 0.15 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 0.65 to 1.0. As of December 31, 2020, the Company was in compliance with all of its debt covenants.
See Note 19 for a discussion of the primary changes related to a First Amendment to Credit Agreement that was entered into by the Company subsequent to December 31, 2020.
Credit agreement. On April 3, 2020, the Company entered into a 364-Day Credit Agreement (the "364-Day Credit Agreement") with Wells Fargo Bank, National Association, as Administrative Agent, and the other agents and lenders party thereto. In May 2020, the Company terminated the 364-Day Credit Agreement in conjunction with the issuance of the 0.25% Convertible Notes. During the year ended December 31, 2020, the Company recognized a $2 million loss on the early extinguishment of debt in other expense in the consolidated statements of operations for unamortized deferred financing costs associated with the 364-Day Credit Agreement. See Note 16 for additional information.

Convertible senior notes. In May 2020, the Company issued $1.3 billion principal amount of 0.25% convertible senior notes due 2025. Interest on the Convertible Notes is payable semiannually in arrears on May 15 and November 15 of each year, beginning on November 15, 2020. The Convertible Notes will mature on May 15, 2025, unless earlier redeemed, repurchased or converted. The Convertible Notes are unsecured obligations ranking equally in right of payment with all other senior unsecured indebtedness of the Company.
The Convertible Notes are convertible into shares of the Company's common stock at an initial conversion rate of 9.1098 shares of the Company's common stock per $1,000 principal amount of the Convertible Notes (subject to adjustment pursuant to the terms of the notes indenture, the "Conversion Rate"), which represents an initial conversion price of $109.77 per share (subject to adjustment pursuant to the terms of the notes indenture, the "Conversion Price"). Upon conversion, the Convertible Notes will be settled in cash, shares of the Company's common stock or a combination thereof, at the Company's election. The Company intends to settle the principal amount of the Convertible Notes in cash.
Holders of the Convertible Notes may convert their notes at their option prior to February 15, 2025 under the following circumstances:
during the quarter following any quarter during which the last reported sales price of the Company's common stock exceeds 130 percent of the Conversion Price for at least 20 trading days;
during the five-day period following any five consecutive trading day period when the trading price of the Convertible Notes is less than 98 percent of the price of the Company's common stock times the Conversion Rate;
upon notice of redemption by the Company; or
upon the occurrence of specified corporate events, including certain consolidations or mergers.
On or after February 15, 2025, until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert their notes at any time. The Company may not redeem the Convertible Notes prior to May 20, 2023, and after such date, may redeem the Convertible Notes only if the last reported sale price of the Company's common stock has been at least 130 percent of the Conversion Price for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period ending on, and including, the trading day immediately preceding the date on which the Company provides the notice of redemption. The redemption price is equal to 100 percent of the principal amount of the Convertible Notes to be redeemed, plus accrued and unpaid interest.
The principal amount and related unamortized issuance costs and discount on the Convertible Notes are as follows:
As of December 31, 2020
(in millions)
Principal amount of Convertible Notes $ 1,323 
Unamortized discount on Convertible Notes (a) (206)
Unamortized issuance costs on Convertible Notes (b) (17)
Net carrying value $ 1,100 
______________________
(a)Upon issuance of the Convertible Notes, the Company recorded $234 million of unamortized discount to additional paid-in capital in the accompanying consolidated balance sheets. The Company will amortize the discount to interest expense at an effective interest rate of 4.3 percent over five years. For the year ended December 31, 2020, the Company amortized $28 million of the discount to interest expense.
(b)Upon issuance of the Convertible Notes, the Company allocated $19 million of unamortized issuance costs to long-term debt and $4 million of unamortized issuance costs to additional paid-in capital in the accompanying consolidated balance sheets. The Company will amortize the issuance costs recorded to long-term debt to interest expense at an effective interest rate of 4.3 percent over five years. For the year ended December 31, 2020 the Company amortized $2 million of issuance costs to interest expense.

Capped call transactions. In connection with the issuance of the Convertible Notes, the Company entered into privately negotiated capped call transactions with certain financial institution counterparties (the "Capped Call"), the purpose of which was to reduce the potential dilution to the Company's common stock upon conversion of the Convertible Notes and/or offset any cash payments the Company is required to make in excess of the principal amount of such converted notes, with such reduction and offset subject to a capped price. The Capped Call transactions have a strike price of $109.77 per share of common

stock and a capped price of $156.21 per share of common stock. The net costs of $113 million incurred to purchase the Capped Call transactions were recorded as a reduction to additional paid-in capital in the accompanying consolidated balance sheets.
Senior notes. During August 2020, the Company issued $1.1 billion of 1.90% senior notes due August 15, 2030 and received proceeds, net of $19 million of issuance costs and discounts, of $1.08 billion. The notes bear an annual interest rate of 1.90 percent and interest is payable semiannually in arrears on February 15 and August 15 of each year, commencing on February 15, 2021. The senior notes are unsecured obligations ranking equally in right of payment with all other senior unsecured indebtedness of the Company.
In May 2020, the Company paid $725 million to complete a cash tender offer for certain of its outstanding senior notes. Associated with the tender offer, the Company settled $360 million of its 3.45% senior notes due 2021, $356 million of its 3.95% senior notes due 2022 and $9 million of its 7.20% senior notes due 2028. The Company expensed unamortized debt discounts and issuance costs associated with the tendered notes of $2 million and recognized a loss on the early extinguishment of debt totaling $23 million. The losses are recorded in other expense in the consolidated statements of operations. See Note 16 for additional information.
The Company's 7.50% senior notes, with a debt principal balance of $450 million, matured and were repaid in January 2020. The Company funded the repayment with cash on hand.
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.

In response to cost savings measures implemented in response to the COVID-19 pandemic, the 401(k) Plan was amended such that the Matching Contributions were reduced from 200 percent to 100 percent of a participant's contributions to the 401(k) Plan that are not in excess of five percent of the participant's annual base salary for each pay period beginning on May 25, 2020. In January 2021, the Matching Contributions were increased from 100 percent of a participant's contributions to the 401(k) Plan that are not in excess of five percent of the participant's annual base salary to 100 percent of a participant's contributions to the 401(k) Plan that are not in excess of ten percent of the participant's annual base salary.

Performance unit awards. Each year, at its discretion, the Company awards 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 value per unit of the 2020, 2019 and 2018 performance unit awards were $184.06, $165.84 and $246.18, respectively, and are being recorded as stock-based compensation expense ratably over the performance period. The fair value of the performance unit awards was determined using the Monte Carlo simulation model that utilizes multiple input variables to 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 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.
Assumptions used to estimate the fair value of performance unit awards granted in each of the following years are as follows: 
2020 2019 2018
Risk-free interest rate 0.68% 2.49% 2.41%
Range of volatilities 30.9%  - 44.7% 27.7%  - 43.4% 30.4%  - 53.3%

(a)Amount reflects the number of performance units initially granted. The actual payout of shares upon vesting may be between zero and 250 percent of the performance units included in this table depending upon the total shareholder return ranking of the Company compared to peer companies at the vesting date.
(b)Units vested reflects the number of performance units that vest upon retirement or departure of eligible officers or when the service period on the award has ended. Awards that vest upon retirement or departure of eligible officers are not transferred to the officer until the original service period of the award lapses. Of the 41,406 units that vested, 4,173 units vested upon retirement of eligible officers in 2020 and will be issued when the performance period ends in 2021 and 2022. On December 31, 2020, the service period lapsed on 62,541 performance unit awards that earned 1.70 shares for each vested award resulting in 106,329 aggregate shares of common stock being issued on January 2, 2021. Of the 62,541 performance unit awards that lapsed, 25,308 units were associated with units that vested in prior years upon retirement or departure of eligible officers.

NOTE 9. 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.

_____________________
(a)Changes in estimates are determined based on several factors, including abandonment cost estimates based on recent actual costs incurred to abandon wells, credit-adjusted risk-free discount rates and well life estimates. The 2020 change in estimate is primarily due to decreases in commodity prices, which had the effect of shortening well life estimates and increasing the present value of the abandonment obligation. The 2019 change in estimate is primarily due to accelerating the forecasted timing of abandoning certain of the Company's vertical oil and gas wells, which had the effect of increasing the present value of the abandonment obligation attributable to those wells.
NOTE 10. Leases
The Company had a variable interest in the entity responsible for constructing the Company's corporate headquarters (the "Hidden Ridge Building"). The Company was not the primary beneficiary of the variable interest entity and only had a profit sharing interest after certain economic returns were achieved. The Company had no exposure to the variable interest entity's losses or future liabilities, if any. In December 2019, the Company sold its interest in the variable interest entity for net cash proceeds of $56 million and recognized a net gain on the sale of the building of $56 million, which is recorded in interest and other income in the consolidated statement of operations. The Company has no continuing involvement in the entity subsequent to the sale. See Note 15 for additional information.

Severance agreements. As of December 31, 2020, 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 $12 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 these 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.

contingencies when information available indicates that a loss is probable and the amount of the loss can be reasonably estimated.
Environmental. Environmental expenditures that relate to an existing condition caused by past operations and that have no future economic benefits are expensed. Environmental 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 or remediation occurs.
Obligations following divestitures. In connection with its divestiture transactions, the Company may retain certain liabilities and provide the purchaser certain indemnifications, subject to defined limitations, which may apply to identified pre-closing matters, including matters of litigation, environmental contingencies, royalty and income taxes. Also associated with its divestiture transactions, the Company has issued and received guarantees to facilitate the transfer of contractual obligations, such as firm transportation agreements or gathering and processing arrangements. The Company does not recognize a liability if the fair value of the obligation is immaterial and the likelihood of making payments under these guarantees is remote.
South Texas Divestiture. In conjunction with the South Texas Divestiture, the Company transferred its long-term midstream agreements and associated MVC's to the buyer. However, the Company retained the obligation to pay 100 percent of any deficiency fees associated with the MVC's from January 2019 through July 2022. The buyer is required to reimburse the Company for 18 percent of the deficiency fees paid by the Company from January 2019 through July 2022; such reimbursement will be paid by the buyer in installments beginning in 2023 through 2025. Assuming 100 percent of the MVC's are paid as deficiency fees, the maximum amount of future payments for this obligation would be approximately $388 million as of December 31, 2020. The Company's estimated deficiency fee obligation as of December 31, 2020 is $333 million, of which $144 million is included in other current liabilities in the consolidated balance sheets. The corresponding estimated deficiency fee receivable from the buyer of $75 million is included in noncurrent other assets in the consolidated balance sheets. The Company has received credit support for the deficiency fee receivable of up to $100 million.
Raton transportation commitments. As part of the Raton Basin Sale, the Company transferred certain gas transportation commitments, which extend through 2032, to the buyer for which the Company has provided a guarantee. Assuming 100 percent of the remaining commitments are paid by the Company under its guarantee, the maximum amount of future payments would be approximately $77 million as of December 31, 2020. The Company has received credit support for the commitments of up to $50 million. The Company paid $11 million in gas transportation fees associated with the transferred commitment for the year ended December 31, 2020 and was fully reimbursed.
West Eagle Ford Shale commitments. In April 2018, the Company completed the sale of its West Eagle Ford Shale gas and liquids field to an unaffiliated third party and transferred certain gas and liquids transportation commitments, which extend through 2022, to the buyer for which the Company has provided a guarantee. Assuming 100 percent of the remaining commitments are paid by the Company under its guarantee, the maximum amount of future payments would be approximately $24 million as of December 31, 2020. The Company has received credit support for the commitments of up to $19 million.

NOTE 12. Related Party Transactions
In December 2018, the Company completed the sale of its pressure pumping assets to ProPetro in exchange for 16.6 million shares of ProPetro common stock and $110 million of cash that was received during the first quarter of 2019. ProPetro is considered a related party as the shares received represent 16 percent of ProPetro's outstanding common stock. In addition to the sale of equipment and related facilities, the Company entered into a long-term agreement with ProPetro, under which it provides pressure pumping and related services. The costs of these services are capitalized in oil and gas properties as incurred. See Note 3 for additional information.
In October 2019, Phillip A. Gobe, a nonemployee member of the Company's board of directors, was appointed by the board of directors of ProPetro to serve as its Executive Chairman, and in March 2020 he was appointed as Chief Executive Officer and Chairman of the Board of Directors. Mark S. Berg, the Company's Executive Vice President, Corporate Operations, serves as a member of the ProPetro board of directors under the Company's right acquired upon the sale of its pressure pumping assets to designate a director to the board of directors of ProPetro so long as the Company owns five percent or more of ProPetro's outstanding common stock.
Based on the Company's ownership in ProPetro and representation on the ProPetro board of directors, ProPetro is considered an affiliate and deemed to be a related party.

NOTE 14. Revenue Recognition
Disaggregated revenue from contracts with purchasers. Revenues on sales of oil, NGL, gas and purchased oil, gas and diesel are recognized when control of the product is transferred to the purchaser and payment can be reasonably assured. Sales prices for oil, NGL and gas are negotiated based on factors normally considered in the industry, such as an index or spot price, distance from the well to the pipeline or market, commodity quality and prevailing supply and demand conditions. Accordingly, the prices received by the Company for oil, NGL and gas generally fluctuate similar to changes in the relevant market index prices.

The Company typically satisfies its performance obligations upon transfer of control as described above in Disaggregated revenue from contracts with purchasers and records the related revenue in the month production is delivered to the purchaser. Settlement statements for sales of oil, NGL, gas and sales of purchased oil, gas and diesel may not be received for 30 to 60 days after the date the volumes are delivered, and as a result, the Company is required to estimate the amount of volumes delivered to the purchaser and the price that will be received for the sale of the product. The Company records the differences between estimates and the actual amounts received for product sales in the month that payment is received from the purchaser. As of December 31, 2020 and 2019, the accounts receivable balance representing amounts due or billable under the terms of contracts with purchasers was $661 million and $968 million, respectively.

NOTE 17. Income Taxes
The Company and its eligible subsidiaries file a consolidated U.S. federal income tax return. Certain subsidiaries are not eligible to be included in the consolidated U.S. federal income tax return and separate provisions for income taxes 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 U.S. federal, state, local and foreign taxing authorities.
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 based on that information, along with other data, reassesses the likelihood that the Company's net operating loss carryforwards ("NOLs") and other deferred tax attributes in the U.S. federal, state, local and foreign tax jurisdictions will be utilized prior to their expiration.
Enactment of the Consolidated Appropriations Act, 2021. On December 27, 2020, President Trump signed into law the Consolidated Appropriations Act, 2021 ("the Act"). The Act includes many tax provisions, including the extension of various expiring provisions, extensions and expansions of certain earlier pandemic tax relief provisions, among other things. The Act did not have a material impact on the Company's current year tax provision or the Company's consolidated financial statements.
Enactment of the Coronavirus Aid, Relief and Economic Security Act. On March 27, 2020, President Trump signed into law the Coronavirus Aid, Relief and Economic Security Act ("CARES Act"). The CARES Act, among other things, includes provisions relating to refundable payroll tax credits, deferment of employer social security payments, net operating loss carryback periods, alternative minimum tax credit refunds, modifications to the net interest deduction limitations and technical corrections to tax depreciation methods for qualified improvement property. The CARES Act did not have a material impact on the Company's current year tax provision or the Company's consolidated financial statements.
Enactment of the Tax Cuts and Jobs Act. On December 22, 2017, the U.S. enacted the Tax Cuts and Jobs Act (the "Tax Reform Legislation"), which introduced significant changes to the U.S. federal income tax law. The changes that most impact the Company include:
A reduction in the federal corporate income tax rate from 35 percent to 21 percent. The rate reduction is effective for the Company as of January 1, 2018.
Repeal of the corporate alternative minimum tax ("AMT"). The Tax Reform Legislation provides that existing AMT credit carryovers are refundable beginning in 2018. As of December 31, 2020, the Company's AMT credit carryovers have been substantially refunded.
The Tax Reform Legislation preserves the deductibility of intangible drilling costs and provides for 100 percent bonus depreciation on personal tangible property expenditures through 2022. The bonus depreciation percentage will be phased out from 2023 through 2026.
The Tax Reform Legislation is a comprehensive bill containing other provisions, such as limitations on the deductibility of interest expense and certain executive compensation, that are not expected to materially affect Pioneer. The ultimate impact of the Tax Reform Legislation may differ from the Company's estimates due to changes in the interpretations and assumptions made by the Company as well as additional regulatory guidance that may be issued.
Uncertain tax positions. The Company had unrecognized tax benefits ("UTBs") resulting from research and experimental expenditures related to horizontal drilling and completion innovations. In December 2019, the Company and the taxing authorities effectively settled the uncertain tax position for the 2012-2015 tax years. In December 2020, the Company and the taxing authorities effectively settled the remaining uncertain tax position for the 2016-2018 tax years. As of December 31, 2020, the Company no longer has any UTBs.

NOTE 18. Net Income (Loss) Per Share
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. Diluted net income (loss) per share attributable to common stockholders is calculated under both the two-class method and the treasury stock method and the more dilutive of the two calculations is presented.
The components of basic and diluted net income (loss) per share attributable to common stockholders are as follows:

______________________
(a)Unvested restricted stock awards represent participating securities because they participate in nonforfeitable dividends with the common equity owners of the Company. Participating share- or unit-based earnings represent the distributed and undistributed earnings of the Company attributable to the participating securities. Unvested restricted stock awards do not participate in undistributed net losses as they are not contractually obligated to do so.
Stock repurchase program. In December 2018, the Company's board of directors authorized a common stock repurchase program that allows the Company to repurchase up to $2 billion of its common stock. Under this stock repurchase program, the Company may repurchase shares from time to time at management's discretion in accordance with applicable securities laws. In addition, the Company may repurchase shares pursuant to a trading plan meeting the requirements of Rule 10b5-1 under the Securities Act of 1934, which would permit the Company to repurchase shares at times that may otherwise be prohibited under the Company's insider trading policy. The stock repurchase program has no time limit, may be modified, suspended or terminated at any time by the board of directors.

NOTE 19. Subsequent Events
Dividends. In February 2021, the board of directors declared a cash dividend of $0.56 per share on the Company's outstanding common stock, payable April 14, 2021 to stockholders of record at the close of business on March 31, 2021.
Parsley Energy Acquisition. On January 12, 2021, the Company acquired Parsley Energy, Inc., a Delaware corporation that previously traded on the NYSE under the symbol "PE" ("Parsley"), pursuant to the Agreement and Plan of Merger, dated as of October 20, 2020, among Pioneer, certain of its subsidiaries, Parsley and Parsley's subsidiary, Parsley Energy, LLC (the "Parsley Acquisition"). On the closing date of the Parsley Acquisition, Parsley merged into a newly formed wholly owned subsidiary of the Company, and the subsidiaries of Parsley, including Jagged Peak Energy LLC ("Jagged Peak"), became indirect subsidiaries of the Company.
As part of the Parsley Acquisition, each eligible share of Parsley Class A common stock and each membership interest unit of Parsley Energy, LLC were automatically converted into the right to receive .1252 shares of Pioneer common stock. As a result, the Company issued approximately 52 million shares of Pioneer common stock upon the consummation of the Parsley Acquisition, representing total stock consideration transferred of approximately $7 billion.
Acquisition costs of $10 million related to the Parsley Acquisition are included in other expense in the Company's consolidated statements of operations for the year ended December 31, 2020. The acquisition will be accounted for as a business combination, with the fair value of consideration allocated to the acquisition date fair value of assets and liabilities acquired. Parsley's post-acquisition date results of operations will be incorporated into the Company's interim condensed consolidated financial statements for the three months ended March 31, 2021.
Parsley is considered a related party as Bryan Sheffield, Parsley's Executive Chairman and one of Parsley's largest stockholders, is the son of Scott Sheffield, Chief Executive Officer of the Company.
First Amendment to Credit Agreement. On January 12, 2021, Pioneer entered into the First Amendment to Credit Agreement (the "Amendment") with Wells Fargo Bank, National Association, as Administrative Agent, and the other agents and lenders party thereto. The primary changes attributable to the Amendment were to increase the aggregate loan commitments from $1.5 billion to $2.0 billion, extend the maturity of the credit facility to January 12, 2026 and to nominally adjust the drawn and undrawn pricing.
Senior notes. On December 30, 2020, Parsley and the other issuers of their senior notes delivered notices of conditional redemption for the Parsley 5.250% Senior Notes due 2025 and the Parsley 5.375% Senior Notes due 2025. Additionally, Pioneer issued a cash tender offer notice to purchase any and all of the Parsley outstanding 5.625% Senior Notes due 2027 and 4.125% Senior Notes due 2028. On January 14, 2021, Pioneer delivered an additional conditional notice of redemption for the Jagged Peak 5.875% Senior Notes due 2026.
In January 2021, the Company issued $750 million of 0.750% Senior Notes that will mature January 15, 2024, $750 million of 1.125% Senior Notes that will mature January 15, 2026 and $1.0 billion of 2.150% Senior Notes that will mature January 15, 2031 (the "January 2021 Senior Notes Offering"). The Company received proceeds, net of $18 million of issuance costs and discounts, of $2.5 billion. Interest on each of the new notes will be payable on January 15 and July 15 of each year. The senior notes are unsecured obligations ranking equally in right of payment with all other senior unsecured indebtedness of the Company.
The Company used the proceeds from the January 2021 Senior Notes Offering to (i) pay $1.6 billion to redeem Parsley's 5.250% Senior Notes due 2025, Parsley's 5.375% Senior Notes due 2025 and Jagged Peak's 5.875% Senior Notes due 2026, and (ii) pay $852 million to purchase a portion of Parsley's 5.625% Senior Notes due 2027 and Parsley's 4.125% Senior Notes due 2028 pursuant to a cash tender offer. In connection with the tender offers, the Company also obtained the requisite consents from holders of Parsley's 5.625% Senior Notes due 2027 and 4.125% Senior Notes due 2028 to amend the indentures pursuant to which the notes were issued to, among other things, (i) eliminate substantially all of the restrictive covenants and related provisions and certain events of default contained in each indenture and (ii) shorten the minimum notice requirement for optional redemptions to three days.
The Company's outstanding 3.45% Senior Notes matured on January 15, 2021. The Company funded the payment of the $140 million principal balance with cash on hand. See Note 7 for additional information regarding the Company's 3.45% Senior Notes.

February 2021 Winter Storm. During February 2021, the Company's operations in West Texas were significantly impacted by winter weather that brought abnormally cold temperatures, along with snow and icy conditions across the state of Texas. The extreme winter weather impacted production operations, midstream infrastructure and power providers throughout the state, along with many other services. As a result, most of the Company's production was offline for about a week, which is expected to impact first quarter 2021 production by approximately 30 MBOPD and 55 MBOEPD.
Early in the weather event, the Company attempted to perform or otherwise satisfy its firm gas sales commitments, but as the impacts of the winter weather became clearer, the Company subsequently issued force majeure notices to its customers given the inability to perform such contracts for a variety of reasons, including significant production being offline, interruptions to midstream operations, the inability to flow gas to markets due to infrastructure downtime and compliance with government orders to direct any available gas volumes towards supporting power generation. Certain of the Company's customers have alleged that the Company's force majeure notices were improper under the applicable contracts. The Company estimates that it incurred incremental cash costs of $75 million to $85 million in connection with its firm gas sales commitments early in the weather event.

Reserve Quantity Information
The estimates of the Company's proved reserves as of December 31, 2020, 2019 and 2018 were based on evaluations prepared by the Company's engineers and audited by independent petroleum engineers with respect to the Company's major properties and prepared by the Company's engineers with respect to all other properties. Proved reserves were estimated in accordance with guidelines established by the U.S. Securities and Exchange Commission (the "SEC") and the FASB, which require that reserve estimates be prepared under existing economic and operating conditions based upon an average of the first-day-of-the-month commodity price during the 12-month period ending on the balance sheet date with no provision for price and cost escalations except by contractual arrangements.
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 commodity 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.

(a)The proved gas reserves as of December 31, 2020, 2019 and 2018 include 115,239 MMcf, 100,236 MMcf and 106,948 MMcf, respectively, of gas that the Company expected to be produced and utilized as field fuel. Field fuel is gas consumed to operate field equipment (primarily compressors) rather than being delivered to a sales point.
(b)Production for 2020, 2019 and 2018 includes 11,201 MMcf, 11,781 MMcf and 13,690 MMcf of field fuel, respectively.

Revisions of previous estimates. Revisions of previous estimates for 2020, 2019 and 2018 were comprised of 145 million barrels of oil equivalent ("MMBOE"), 26 MMBOE and 29 MMBOE, respectively, of positive technical revisions. The 145 MMBOE of positive technical revisions in 2020 were primarily attributable to 167 MMBOE of positive NGLs and gas revisions as a result of (i) increasing wet gas production (as a percentage of a horizontal well's total production) over time, (ii) new processing facilities and takeaway capacity being placed into service during 2019 and 2020, which had the effect of lowering line pressures, and (iii) increased recovery rates for NGLs. The positive technical revisions for 2019 and 2018 were primarily attributable to improved performance from horizontal wells placed on production in the Spraberry/Wolfcamp oil field in the Permian Basin. Revisions of previous estimates associated with changes in NYMEX oil and gas prices resulted in negative price revisions of 83 MMBOE and 11 MMBOE in 2020 and 2019, respectively, and positive price revisions of 20 MMBOE in 2018. Of the negative price revisions for 2020, 46 MMBOE were attributable to proved oil reductions.

Associated therewith, during 2020, 2019 and 2018, the Company added 212 MMBOE, 276 MMBOE and 265 MMBOE of net reserves from extensions and discoveries, respectively, of which 29 MMBOE, 36 MMBOE and 23 MMBOE, respectively, were recorded as proved undeveloped reserves. The Permian Basin's geology is complex, consisting of multiple stacked horizons/zones, each with its own unique characteristics. The Company recognizes proved undeveloped reserves on undrilled acreage directly offsetting development areas that are reasonably certain of production when drilled, or when reliable technology provides reasonable certainty of economic producibility. The Company did not add any proved undeveloped reserves using reliable technology during the years 2018 - 2020.
Sales of minerals-in-place. Sales of minerals-in-place in 2020 were primarily related to divesting non-core Permian Basin unproved properties and associated producing wells. In 2019, sales of minerals-in-place were primarily related to the sale of the Company's Eagle Ford assets and other remaining South Texas assets. In 2018, sales of minerals-in-place were primarily related to the sale of the Company's West Eagle Ford Shale assets, Raton Basin assets and West Panhandle assets. See Note 3 to the accompanying financial statements for additional information.
Purchases of minerals-in-place. Purchases of minerals-in-place during 2020 were primarily attributable to acquisitions in the Company's Spraberry/Wolfcamp oil field in the Permian Basin.

Proved undeveloped reserves activity is as follows (in MBOE):    
Year Ended December 31, 2020
Beginning proved undeveloped reserves 57,655 
Revisions of previous estimates (1,190)
Extensions and discoveries 28,763 
Transfers to proved developed (25,079)
Ending proved undeveloped reserves 60,149 
As of December 31, 2020, the Company had 60 proved undeveloped well locations as compared to 60 and 134 for December 31, 2019 and December 31, 2018, respectively. The Company has no proved undeveloped well locations that are scheduled to be drilled more than five years from their original date of booking.
The changes in proved undeveloped reserves during 2020 were comprised of the following items:
Revisions of previous estimates. Revisions of previous estimates were primarily comprised of one MMBOE related to negative technical revisions.
Extensions and discoveries. Extensions and discoveries were primarily comprised of proved reserve additions attributable to the Company's successful horizontal drilling program in the Spraberry/Wolfcamp oil field in the Permian Basin.
Transfers to proved developed. Transfers to proved developed reserves represented those undeveloped proved reserves that moved to proved developed as a result of development drilling. The company incurred development costs directly related to the transfer of proved reserves of approximately $166 million, or $6.62 per BOE, and developed 43 percent of its 2019 proved undeveloped reserves. Development costs related to the transfer of proved reserves were incurred during 2019 and 2020.
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 2020.
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, sales of investments, availability under its credit facility, or external financing sources to fund these and other capital expenditures, including exploratory/extension drilling and acquisitions.

(a)Production and cash flows represent the drilling results from the respective year plus the incremental effects of proved undeveloped drilling beginning in 2021.
(b)Future development costs represents $5 million of net abandonment costs in years beyond the forecasted years.
The Company's 2020 estimated future production costs attributable to proved undeveloped reserves of $7.68 per BOE are less than the forecasted future production costs attributable to total proved reserves of $11.63 per BOE for the following reasons:
As of December 31, 2020, the majority of the Company's proved developed producing wells are comprised of legacy vertical wells that have higher production costs, on a per BOE basis, than the Company's proved developed producing horizontal wells. The total proved reserves production cost per BOE of $11.63 is comprised of $10.14 per BOE for horizontal wells and $23.57 per BOE for vertical wells.
The estimated future production costs of $7.68 per BOE associated with proved undeveloped reserves is comprised entirely of horizontal wells is marginally lower than the $10.14 per BOE average of the Company's producing horizontal wells included in total proved reserves. The lower costs take into account the initial production rates of new wells, which are higher at the beginning of a well's life, and result in a lower overall production cost, on a per BOE basis, when looked at over the well's total productive life versus a well that is later in its productive life. In addition, the future production costs on proved undeveloped horizontal wells also reflect the economies of scale of adding the wells to existing infrastructure, allowing the Company to spread certain fixed costs over a larger production volume.

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.
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 standardized measure of discounted future cash flows as well as a rollforward in total for each respective year are as follows:

Selected Quarterly Financial Results
In the fourth quarter of 2020, the Company determined that certain amounts reported in the Company's previously issued unaudited interim consolidated statements of operations and consolidated balance sheets contained misstatements (see Note 2 for further details). In accordance with Staff Accounting Bulletin No. 99, Materiality, management evaluated the materiality of the misstatements from a qualitative and quantitative perspective and concluded that the misstatements were not material to the Company's previously issued first and second quarter 2020 interim consolidated financial statements. The Company concluded that the misstatements were material to the three and nine months ended September 30, 2020 interim consolidated financial statements. Accordingly, the Company has revised its first and second quarter 2020 interim consolidated financial statements and has restated its three and nine months ended September 30, 2020 interim consolidated financial statements.
The effects of the adjustments to the Company's previously reported 2020 quarterly consolidated statements of operations on a standalone quarter basis is as follows (in millions, except for per share data):

______________
(a)During the Company's review of its marketing contracts during the fourth quarter of 2020, the Company identified two long-term marketing contracts that should have been accounted for as derivative contracts. The contracts were entered in October 2019, each with January 1, 2021 contract commencement date and a December 31, 2026 contract termination date. The effect of the misstatements was an understatement of noncash derivative gains of $6 million for the quarter ended March 31, 2020, an overstatement of noncash derivative losses of $22 million for the quarter ended June 30, 2020 and an overstatement of noncash derivative gains of $85 million for the quarter ended September 30, 2020.
(b)During the fourth quarter of 2020, the Company also made certain other immaterial corrections to previously reported quarters. The Company determined that no adjustments were needed for interim periods prior to March 31, 2020.

ITEM 9A.    CONTROLS AND PROCEDURES
Background. In connection with the preparation of this Report, management of the Company became aware that the unaudited consolidated financial statements for the three and nine months ended September 30, 2020, contained misstatements related to two long-term marketing contracts that should have been accounted for as derivative contracts. The contracts were executed in October 2019, each with a January 1, 2021 contract commencement date and a December 31, 2026 contract termination date. In order to properly account for the contracts as derivatives, the Company has withdrawn reliance on its previously reported unaudited consolidated financial statements for the three months and nine months ended September 30, 2020 and has restated the unaudited consolidated financial statements for those periods in this Annual Report on Form 10-K. See the Company's Current Report on Form 8-K filed on February 25, 2021 and "Unaudited Supplementary Information" included in "Item 8. Financial Statements and Supplementary Data" of this Report.
Management of the Company has concluded that the control deficiency that resulted in the failure to detect the misstatement described above is a material weakness in the Company's internal control over financial reporting as of December 31, 2020 related to the design and maintenance of internal controls over the review of material marketing contracts that could have elements of a derivative. Management of the Company therefore concluded that the Company's disclosure controls and procedures were not effective at September 30, 2020 or December 31, 2020 and that the Company's internal control over financial reporting was not effective at a reasonable assurances level at December 31, 2020. Other than the material weakness identified above, there were no changes to the Company's internal control over financial reporting (as defined in Rules 13a-15(f) under the Exchange Act) that occurred during the three months ended December 31, 2020 that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.
Evaluation of disclosure controls and procedures. Disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) are designed to ensure that information required to be disclosed in the reports the Company files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms and that such information is accumulated and communicated to the Company's management, including the principal executive officer and principal financial officer, to allow timely decisions regarding required disclosure.
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 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 not effective, as of the end of the period covered by this Report, because of the existence of the material weakness in internal control over financial reporting described below (which the Company views as an integral part of the Company's disclosure controls and procedures).
MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING
The Company's management 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 of directors, 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 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 issuer are being made only in accordance with authorizations of management and directors of the issuer; 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.
The Company's management, with the participation of its principal executive officer and principal financial officer assessed the effectiveness, as of December 31, 2020, 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 (2013)," issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on the assessment, management
125

Table of Contents
determined that the Company's internal control over financial reporting was not effective at a reasonable assurance level as of December 31, 2020 because of the material weakness described below.
Material weakness. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is reasonable possibility that a material misstatement of the Company's annual or interim consolidated financial statements will not be prevented or detected on a timely basis. Management did not design and maintain effective controls to identify and evaluate material marketing contracts that could have elements of a derivative, which failure represents a material weakness in the Company's internal control over financial reporting. This material weakness in the Company's internal control over financial reporting resulted in the accounting corrections that led to the restatement of previously issued financial statements.
Remediation Plan. Management is developing and plans to implement the following internal controls to remediate the control deficiency related to the review of material marketing contracts that could have elements of a derivative:
Implement new controls surrounding the review and identification of unique marketing contract terms that would indicate that the contract may be a derivative, with any identified contract requiring a comprehensive technical accounting assessment and
Engage a third party to review marketing contract terms with unique provisions on an as-required basis.
While management believes that it has implemented the principal remediation measures needed for this material weakness prior to issuance of this Report, including performing a second review of all material third-party marketing contracts, the material weakness will not be considered fully remediated until all aspects of the controls operate for a sufficient period of time to allow management to conclude that these controls are operating effectively. The Company will monitor the effectiveness of its remediation plan and actions and will refine its remediation plan as appropriate.
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, 2020.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Stockholders and the Board of Directors of Pioneer Natural Resources Company
Opinion on Internal Control over Financial Reporting
We have audited Pioneer Natural Resources Company's internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Pioneer Natural Resources Company (the Company) has not maintained effective internal control over financial reporting as of December 31, 2020, based on the COSO criteria.
A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the company's annual or interim financial statements will not be prevented or detected on a timely basis. The following material weakness has been identified and included in management's assessment. Management did not design and maintain effective controls to identify and evaluate material marketing contracts that could have elements of a derivative.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of Pioneer Natural Resources Company as of December 31, 2020 and 2019, the related consolidated statements of operations, equity and cash flows for each of the three years in the period ended December 31, 2020, and the related notes. This material weakness was considered in determining the nature, timing and extent of audit tests applied in our audit of the 2020 consolidated financial statements, and this report does not affect our report dated March 1, 2021 that expressed an unqualified opinion thereon.
Basis for Opinion
The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management's Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.
Our audit 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.
Definition and Limitations of Internal Control Over Financial Reporting
A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

EXHIBIT 3.2

SIXTH AMENDED AND RESTATED BYLAWS OF PIONEER NATURAL RESOURCES COMPANY

A Delaware Corporation


PREAMBLE

These bylaws are subject to, and governed by, the General Corporation Law of the State of Delaware (the “Delaware General Corporation Law”) and the certificate of incorporation of Pioneer Natural Resources Company, a Delaware corporation (the “Company”). In the event of a direct conflict between the provisions of these bylaws and the mandatory provisions of the Delaware General Corporation Law or the provisions of the certificate of incorporation of the Company, such conflicting provisions of the Delaware General Corporation Law or the certificate of incorporation of the Company, as the case may be, will be controlling.

ARTICLE ONE: OFFICES

1.1 Registered Office and Agent. The registered office and registered agent of the Company shall be as designated from time to time by the appropriate filing by the Company in the office of the Secretary of State of the State of Delaware.

1.2 Other Offices. The Company may also have offices at such other places, both within and without the State of Delaware, as the board of directors may from time to time determine or as the business of the Company may require.

ARTICLE TWO: MEETINGS OF STOCKHOLDERS

2.1 Annual Meeting. An annual meeting of stockholders of the Company shall be held each calendar year on such date and at such time as shall be designated from time to time by the board of directors and stated in the notice of the meeting or in a duly executed waiver of notice of such meeting. At such meeting, the stockholders shall elect directors and transact such other business as may properly be brought before the meeting.

2.2 Special Meeting. Except as otherwise required by law, special meetings of the common stockholders of the Company, and any proposals to be considered at such meetings, may be called and proposed exclusively by the board of directors, pursuant to a resolution approved by a majority of the members of the board of directors at the time in office, and no stockholder of the Company shall require the board of directors to call a special meeting of common stockholders or to propose business at a special meeting of common stockholders. A special meeting shall be held on such date and at such time as shall be designated by the resolution calling the meeting and stated in the notice of the meeting or in a duly executed waiver of notice of such meeting. Only such business shall be transacted at a special meeting as may be stated or indicated in the notice of such meeting or in a duly executed waiver of notice of such meeting.
2.3 Place of Meetings. An annual meeting of stockholders may be held at any place within or without the State of Delaware designated by the board of directors. A special meeting of stockholders may be held at any place within or without the State of Delaware designated in the notice of the meeting or a duly executed waiver of notice of such meeting. The board of directors may, in its sole discretion, determine that a meeting of stockholders shall not be held at any place, but may instead be held solely by means of remote communication as authorized by the Delaware General Corporation Law. In the absence



of any such designation or determination by the board of directors, meetings of stockholders shall be held at the principal office of the Company unless another place is designated for meetings in the manner provided herein.

2.4 Meeting Attendance via Remote Communication Equipment. If authorized by the board of directors in its sole discretion, and subject to such guidelines and procedures as the board of directors may adopt, stockholders and proxyholders not physically present at a meeting of stockholders may, by means of remote communication: (a) participate in a meeting of stockholders and (b) be deemed present in person and vote at a meeting of stockholders, whether such meeting is to be held at a designated place or solely by means of remote communication, provided that (i) the Company shall implement reasonable measures to verify that each person deemed present and permitted to vote at the meeting by means of remote communication is a stockholder or proxyholder, (ii) the Company shall implement reasonable measures to provide such stockholders and proxyholders a reasonable opportunity to participate in the meeting and to vote on matters submitted to the stockholders, including an opportunity to read or hear the proceedings of the meeting substantially concurrently with such proceedings, and (iii) if any stockholder or proxyholder votes or takes other action at the meeting by means of remote communication, a record of such vote or other action shall be maintained by the Company.

2.5 Notice. Written or printed notice stating the place, if any, day and time of each meeting of the stockholders, the means of remote communications, if any, by which stockholders and proxyholders may be deemed to be present in person and vote at such meeting, the record date for determining the stockholders entitled to vote at the meeting, if such date is different from the record date for determining stockholders entitled to notice of the meeting, and, in case of a special meeting, the purpose or purposes for which the meeting is called, shall be delivered in accordance with Section 5.1 not less than ten nor more than 60 days before the date of the meeting by or at the direction of the board of directors, the Chairman of the Board if such office has been filled (otherwise, the Chief Executive Officer) or the Secretary, to each stockholder of record entitled to vote at such meeting. If such notice is to be sent by mail, it shall be directed to such stockholder at his or her address as it appears on the records of the Company, unless he or she shall have filed with the Secretary of the Company a written request that notices to him or her be mailed to some other address, in which case it shall be directed to him or her at such other address. Notice of any meeting of stockholders shall not be required to be given to any stockholder who (i) attends such meeting in person or by proxy and (ii) does not, at the beginning of such meeting, object to the transaction of any business because the meeting is not lawfully called or convened, or to any stockholder who, either before or after the meeting, submits a waiver of notice. The board of directors may cancel, postpone or reschedule any previously scheduled annual meeting or any special meeting called in accordance with these bylaws.
2.6 Voting List. At least ten days before each meeting of stockholders, the Secretary or other officer of the Company who has charge of the Company’s stock ledger, either directly or through another officer appointed by him or her or through a transfer agent appointed by the board of directors, shall prepare a complete list of stockholders entitled to vote thereat, arranged in alphabetical order and showing the address of each stockholder and number of shares registered in the name of each stockholder. The Company shall not be required to include electronic mail addresses or other electronic contact information on such list. For a period of ten days prior to such meeting, such list shall be kept open to the examination of any stockholder for any purpose germane to the meeting (i) on a reasonably accessible electronic network, provided that the information required to gain access to such list is provided with the notice of the meeting or (ii) during ordinary business hours at the Company’s principal place of business. In the event that the Company determines to make the list available on an electronic network, the Company may take reasonable steps to ensure that such information is available only to stockholders of the Company. If the meeting is to be held at a place, then the list shall be produced and kept at the time and place of the meeting during the whole time thereof and may be examined by any stockholder who is present. If the meeting is to be held solely by means of remote communication, then the list shall also be



open to the examination of any stockholder during the whole time of the meeting on a reasonably accessible electronic network, and the information required to access such list shall be provided with the notice of the meeting.

2.7 Quorum; Adjournment. The holders of a majority of the shares entitled to vote, present in person or represented by proxy, shall constitute a quorum at any meeting of stockholders, except as otherwise provided by law, the certificate of incorporation of the Company, or these bylaws. The chairman of a meeting of stockholders or holders of a majority in voting power of the stock of the Company entitled to vote at a meeting of stockholders who are present, in person or by proxy, at such meeting of stockholders may adjourn such meeting or any adjournment thereof, from time to time, whether or not there is a quorum. No notice of the adjourned meeting need be given if the date, time and place, if any, and the means of remote communication, if any, by which the stockholders and proxyholders may be deemed to be present in person and vote at such adjourned meeting are announced at the meeting of stockholders at which adjournment is taken; provided, however that if the date of any adjourned meeting is more than 30 days after the date for which notice was originally given, notice of the date, time and place, if any, and the means of remote communication, if any, of the adjourned meeting shall be given to each stockholder of record entitled to vote at the meeting in conformity with these bylaws. If, after the adjournment, a new record date for determination of stockholders entitled to vote is fixed for the adjourned meeting, the board of directors shall fix as the record date for determining stockholders entitled to notice of such adjourned meeting the same or an earlier date as that fixed for determination of stockholders entitled to vote at the meeting, and shall give notice of the adjourned meeting to each stockholder of record as of the record date fixed for notice of such adjourned meeting. At any adjourned meeting at which a quorum is present, in person or by proxy, any business may be transacted which may have been transacted at the original meeting had a quorum been present, in person or by proxy. Stockholders present at a duly convened meeting of stockholders at which a quorum is present when such meeting of stockholders convenes may continue to transact business until adjournment, notwithstanding the subsequent withdrawal of sufficient stockholders or proxyholders to reduce the total number of voting shares below the number of shares required for a quorum.

2.8 Required Vote. When a quorum is present at any meeting of stockholders, any question, other than the election of directors, brought before such meeting shall be decided by the affirmative vote of the majority of shares present in person or represented by proxy at the meeting and entitled to vote on the subject matter thereof, unless the question is one on which, by express provision of statute, the certificate of incorporation of the Company, or these bylaws, a different vote is required, in which case such express provision shall govern and control the decision of such question.

2.9 Method of Voting; Proxies. Except as otherwise provided in the certificate of incorporation of the Company or by law, each outstanding share, regardless of class, shall be entitled to one vote on each matter submitted to a vote at a meeting of stockholders. Elections of directors need not be by written ballot. At any meeting of stockholders, every stockholder having the right to vote may vote in person or may authorize another person or persons to act for such stockholder by proxy in any manner permitted by law. Each such proxy shall be filed with the Secretary of the Company before or at the time of the meeting. No proxy shall be valid after three years from its date, unless otherwise provided in the proxy. If no date is stated in a proxy, such proxy shall be presumed to have been dated on the date of the meeting at which it is to be voted. Each proxy shall be revocable unless expressly provided therein to be irrevocable and coupled with an interest sufficient in law to support an irrevocable power or unless otherwise made irrevocable by law.

2.10 Record Date.




(a) So that the Company may determine the stockholders entitled to notice of any meeting of stockholders or any adjournment thereof, the board of directors may fix a record date, which record date shall be on or after the date upon which the resolution fixing the record date is adopted by the board of directors, and which record date shall, unless otherwise required by law, not be more than 60 nor less than ten days before the date of such meeting. If the board of directors so fixes a date, such date shall also be the record date for determining the stockholders entitled to vote at such meeting unless the board of directors determines, at the time it fixes such record date, that a later date on or before the date of the meeting shall be the date for making such determination. If no record date is fixed by the board of directors, the record date for determining stockholders entitled to notice of and to vote at a meeting of stockholders shall be at the close of business on the day next preceding the day on which notice is given, or, if notice is waived, at the close of business on the day next preceding the day on which the meeting is held. A determination of stockholders of record entitled to notice of or to vote at a meeting of stockholders shall apply to any adjourned meeting; provided, however, that the board of directors may fix a new record date for determination of stockholders entitled to vote at the adjourned meeting, and in such case shall also fix as the record date for stockholders entitled to notice of such adjourned meeting the same or an earlier date as that fixed for determination of stockholders entitled to vote at the adjourned meeting.

(b) So that the Company may determine the stockholders entitled to receive payment of any dividend or other distribution or allotment of any rights, or entitled to exercise any rights in respect of any change, conversion or exchange of stock or for the purpose of any other lawful action, the board of directors may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the board of directors, and which record date shall not be more than 60 days prior to such action. If no record date is fixed by the board of directors, the record date for determining stockholders for any such purpose shall be the day on which the board of directors adopts the resolution relating thereto.

2.11 Advance Notice of Stockholder Business and Nominations.

(a) Annual Meetings of Stockholders.

(i)Nominations of persons for election to the board of directors and the proposal of other business to be considered by the stockholders may be made at an annual meeting of stockholders only (A) pursuant to the Company’s notice of meeting (or any supplement thereto), (B) by or at the direction of the board of directors or any committee thereof or (C) by any stockholder of the Company who (x) was a stockholder of record of the Company both at the time the notice provided for in this Section 2.11 is delivered to the Secretary of the Company and at the time of the annual meeting, (y) is entitled to vote at the meeting and (z) complies with the notice procedures and other requirements set forth in this Section 2.11. In addition, if the proposal is made on behalf of a beneficial owner other than the stockholder of record, such beneficial owner must be the beneficial owner of stock of the Company both at the time of giving of notice provided for in this Section 2.11 and at the time of the annual meeting.

(ii)For any nominations or other business to be properly brought before an annual meeting by a stockholder pursuant to Section 2.11(a)(i)(C) (or on behalf of a beneficial owner other than the stockholder of record), the stockholder must have given timely notice thereof in writing to the Secretary of the Company and any such proposed business (other than the nominations of persons for election to the board of directors) must constitute a proper matter for stockholder action. To be timely, a stockholder’s notice must be received by the Secretary at the Company’s principal executive offices no later



than 60 days before the annual meeting of stockholders or (if later) ten days after the first public notice of that meeting is sent to stockholders. In no event shall the adjournment or postponement of an annual meeting or the public announcement of the adjournment or postponement of an annual meeting commence a new time period (or extend any time period) for the giving of a stockholder’s notice as described above. As to each person whom the stockholder proposes to nominate for election as a director, such stockholder’s notice must (A) set forth (x) such person’s name, business address and telephone number, and residence address and telephone number, (y) the number of shares, if any, of each class and series of stock of the Company owned beneficially by that nominee, and (z) all other information relating to such person that is required to be disclosed in solicitations of proxies for election of directors in an election contest, or is otherwise required, in each case pursuant to and in accordance with Section 14(a) of the Securities Exchange Act of 1934 and the rules and regulations promulgated thereunder (inclusive of such rules and regulations, the “Exchange Act”), and (B) be accompanied by (x) a notarized letter signed by such person stating his or her acceptance of the nomination by that stockholder, stating his or her intention to serve as director if elected, and consenting to being named as a nominee for director in any proxy statement relating to such election and (y) the irrevocable, contingent resignation referred to in Section 3.2(a). The Company may require any proposed nominee to furnish such other information (A) as the Company may reasonably require to determine the eligibility of such proposed nominee to serve as a director of the Company or (B) that the Company believes could be material to a reasonable stockholder’s understanding of the independence (both from management and from the stockholder or, if the proposal is made on behalf of a beneficial owner other than the stockholder of record, from such beneficial owner) or qualifications of such proposed nominee.

(iii) As to any other business that the stockholder proposes to bring before an annual meeting (including on behalf of a beneficial owner other than such stockholder), such stockholder’s notice shall set forth (1) a description of the nature of the proposed business with reasonable particularity, (2) the exact text of the proposal or business (including the text of any resolutions proposed for consideration and in the event that such business includes a proposal to amend these bylaws, the language of the proposed amendment), and the reasons for conducting that business at the annual meeting, and (3) any interest in such business of such stockholder and the beneficial owner, if any, on whose behalf the proposal is made.

(iv) As to the stockholder giving the notice and the beneficial owner, if any, on whose behalf the nomination or proposal is made, such stockholder’s notice shall set forth (1) the name, business address and telephone number and residence address and telephone number of such stockholder and such beneficial owner (including, if applicable, the name and address as they appear on the Company’s books), (2) the class or series and number of shares of stock of the Company that are owned beneficially and of record by such stockholder and such beneficial owner, (3) a description of any agreement, arrangement or understanding with respect to the nomination or proposal between or among such stockholder and/or such beneficial owner, any of their respective affiliates or associates, and any others acting in concert with any of the foregoing, including, in the case of a nomination, the nominee, (4) a description of any agreement, arrangement or understanding (including any derivative or short positions, profit interests, options, warrants, convertible securities, stock appreciation or similar rights, hedging transactions, and borrowed or loaned shares) that has been entered into as of the date of the stockholder’s notice by, or on behalf of, such stockholder and such beneficial



owner, whether or not such instrument or right shall be subject to settlement in underlying shares of stock of the Company, the effect or intent of which is to mitigate loss to, manage risk or benefit of share price changes for, or increase or decrease the voting power of, such stockholder or such beneficial owner, with respect to securities of the Company, (5) a representation that such stockholder is a holder of record of stock of the Company entitled to vote at such meeting and intends to appear in person or by proxy at the meeting to propose such business or nomination, (6) a representation as to whether such stockholder or such beneficial owner, if any, intends or is part of a group that intends (x) to deliver a proxy statement and/or form of proxy to holders of at least the percentage of the Company’s outstanding stock required to approve or adopt the proposal or elect the nominee and/or (y) otherwise to solicit proxies or votes from stockholders in support of such proposal or nomination, and (7) any other information relating to such stockholder and such beneficial owner, if any, required to be disclosed in a proxy statement or other filings required to be made in connection with solicitations of proxies for, as applicable, the proposal and/or for the election of directors in an election contest pursuant to and in accordance with Section 14(a) of the Exchange Act.

(v) The notice requirements of Section 2.11(a) shall be deemed satisfied by a stockholder (or by a beneficial owner other than a stockholder of record) with respect to business other than a nomination if the stockholder or such beneficial owner has notified the Company of such stockholder’s intention to present a proposal at an annual meeting in compliance with the Exchange Act and such proposal has been included in a proxy statement that has been prepared by the Company to solicit proxies for such annual meeting.

(b) Special Meetings of Stockholders. In the event the Company calls a special meeting of stockholders the purposes of which include the election of one or more directors to the board of directors, nominations of persons for such election may be made (i) by or at the direction of the board of directors or any committee thereof or (ii) by any stockholder of the Company who (x) was a stockholder of record of the Company both at the time the notice provided for in this Section 2.11 is delivered to the Secretary of the Company and at the time of the special meeting, (y) is entitled to vote at the meeting and (z) complies with the notice procedures and other requirements set forth in this Section 2.11 (including Section 2.11(a)(ii)). In addition, if the nomination is made on behalf of a beneficial owner other than the stockholder of record, such beneficial owner must be the beneficial owner of stock of the Company both at the time of giving of notice provided for in this Section 2.11 and at the time of the special meeting. For any nomination to be properly brought before such a special meeting by a stockholder pursuant to the first sentence of this Section 2.11(b), the stockholder must have given timely notice thereof in writing to the Secretary of the Company. To be timely, a stockholder’s notice must be received by the Secretary at the Company’s principal executive offices not earlier than the close of business on the 120th day prior to such special meeting and not later than the close of business on the later of the 90th day prior to such special meeting or the 10th day following the day on which public announcement is first made of the date of the special meeting and of the nominees proposed by the board of directors to be elected at such meeting. In no event shall the adjournment or postponement of a special meeting or the public announcement of an adjournment or postponement of a special meeting commence a new time period (or extend any time period) for the giving of a stockholder’s notice as described above.

(c) General.
(i) Except as otherwise expressly provided in any applicable rule or regulation promulgated under the Exchange Act, only such persons who are nominated in



accordance with the procedures set forth in this Section 2.11 are eligible to be elected at an annual or special meeting of stockholders of the Company to serve as directors and only such business shall be conducted at a meeting of stockholders as shall have been brought before the meeting in accordance with the procedures set forth in this Section 2.11.

(ii) Except as otherwise provided by law, the chairman of the meeting shall have the power and duty (x) to determine whether a nomination or any business proposed to be brought before the meeting was made or proposed, as the case may be, in accordance with the procedures set forth in this Section 2.11 (including whether the stockholder or beneficial owner, if any, on whose behalf the nomination or proposal is made solicited (or is part of a group which solicited) or did not so solicit, as the case may be, proxies or votes in support of such stockholder’s nominee or proposal in compliance with such stockholder’s representation as required by Section 2.11(a)(iv)) and (y) if any proposed nomination or business was not made or proposed in compliance with this Section 2.11, not to permit any such business (or voting with respect to any such nominee) to be transacted.

(iii) Notwithstanding the foregoing provisions of this Section 2.11, unless otherwise required by law, if the stockholder (or a qualified representative of the stockholder) does not appear at the annual or special meeting of stockholders of the Company to present a nomination or proposed business, the nomination shall be disregarded and such proposed business shall not be transacted, notwithstanding that proxies in respect of such vote may have been received by the Company. For purposes of this Section 2.11, to be considered a qualified representative of the stockholder, a person must be a duly authorized officer, manager or partner of such stockholder or must be authorized by a writing executed by such stockholder or an electronic transmission delivered by such stockholder to act for such stockholder as proxy at the meeting of stockholders and such person must produce such writing or electronic transmission, or a reliable reproduction of the writing or electronic transmission, at the meeting of stockholders.

(iv) For purposes of this Section 2.11, “public announcement” includes disclosure in a press release reported by the Dow Jones News Service, Associated Press or other national news service or in a document publicly filed by the Company with the Securities and Exchange Commission (the “SEC”) pursuant to Section 13, 14 or 15(d) of the Exchange Act.

(v) Notwithstanding the foregoing provisions of this Section 2.11, a stockholder shall also comply with all applicable requirements of the Exchange Act with respect to the matters set forth in this Section 2.11; provided, however, that any references in these bylaws to the Exchange Act are not intended to and shall not limit any requirements applicable to nominations or proposals as to any other business to be considered pursuant to this Section 2.11 (including paragraph (a)(i)(C) and paragraph (b) hereof), and compliance with paragraph (a)(i)(C) and paragraph (b) of this Section 2.11 shall be the exclusive means for a stockholder to make nominations or submit other business (other than, as provided in Section 2.11(a)(v), business other than nominations brought properly under and in compliance with Rule 14a-8 of the Exchange Act, as may be amended from time to time). Nothing in this Section 2.11 shall be deemed to affect any rights of stockholders to request inclusion of proposals or nominations in the Company’s proxy statement pursuant to the Exchange Act.




2.12 Conduct of Meeting. The Chairman of the Board, if such office has been filled, shall preside at all meetings of stockholders. If such office has not been filled, or if the Chairman of the Board is absent or otherwise unable to act, the Chief Executive Officer shall preside unless the board of directors designates a member of the board to preside. The Secretary shall keep the records of each meeting of stockholders. In the absence or inability to act of any such officer, such officer’s duties shall be performed by the officer given the authority to act for such absent or non-acting officer under these bylaws or by some person appointed by the meeting. The board of directors may adopt such rules and regulations for the conduct of any meeting of stockholders as it shall deem appropriate. Except to the extent inconsistent with these bylaws or such rules and regulations as adopted by the board of directors, the chairman of each meeting of stockholders shall have the right and authority to convene and to adjourn the meeting, to prescribe such rules, regulations and procedures and to do all such acts as, in the judgment of such chairman, are appropriate for the proper conduct of the meeting. Such rules, regulations or procedures, whether adopted by the board of directors or prescribed by the chairman of the meeting, may include, without limitation, the following: (a) the establishment of an agenda or order of business for the meeting; (b) rules and procedures for maintaining order at the meeting and the safety of those present; (c) limitations on attendance at or participation in the meeting to stockholders of record of the Company, their duly authorized and constituted proxies or such other persons as the chairman of the meeting shall determine; (d) restrictions on entry to the meeting after the time fixed for the commencement thereof; and (e) limitations on the time allotted to questions or comments by participants. Unless and to the extent determined by the board of directors or the chairman of the meeting, meetings of stockholders are not required to be held in accordance with the rules of parliamentary procedure.

2.13 Inspectors. The board of directors may, in advance of any meeting of stockholders, appoint one or more inspectors to act at such meeting or any adjournment thereof. If any of the inspectors so appointed shall fail to appear or act, the chairman of the meeting shall, or if inspectors shall not have been appointed, the chairman of the meeting may, appoint one or more inspectors. Each inspector, before entering upon the discharge of his or her duties, shall take and sign an oath faithfully to execute the duties of inspector at such meeting with strict impartiality and according to the best of his or her ability. The inspectors shall determine the number of shares of capital stock of the Company outstanding and the voting power of each, the number of shares represented at the meeting, the existence of a quorum, and the validity and effect of proxies and shall receive votes or ballots, hear and determine all challenges and questions arising in connection with the right to vote, count and tabulate all votes or ballots, determine the results, and do such acts as are proper to conduct the election or vote with fairness to all stockholders. On request of the chairman of the meeting, the inspectors shall make a report in writing of any challenge, request, or matter determined by them and shall execute a certificate of any fact found by them. No director or candidate for the office of director shall act as an inspector of an election of directors. Inspectors need not be stockholders.

2.14 Stockholder Nominations Included in the Company’s Proxy Materials
.
(a) Inclusion of Nominee in Proxy Statement. Subject to the provisions of this Section 2.14, if expressly requested in the relevant Nomination Notice (as defined below), the Company shall include in its proxy statement for any annual meeting of stockholders: (i) the name of any person nominated for election (the “Stockholder Nominee”), which shall also be included on the Company’s form of proxy and ballot, by any Eligible Stockholder (as defined below) or group of up to 20 Eligible Stockholders that has (individually and, in the case of a group, collectively) satisfied, as determined by the board of directors or its designee acting in good faith, all applicable conditions and complied with all applicable procedures set forth in this Section 2.14



(such Eligible Stockholder or group of Eligible Stockholders being a “Nominating Stockholder”); (ii) disclosure about the Stockholder Nominee and the Nominating Stockholder required under the rules of the SEC or other applicable law to be included in the proxy statement; (iii) any statement included by the Nominating Stockholder in the Nomination Notice for inclusion in the proxy statement in support of the Stockholder Nominee’s election to the board of directors (subject, without limitation, to Section 2.14(e)(ii)), if such statement does not exceed 500 words; and (iv) any other information that the Company or the board of directors determines, in their discretion, to include in the proxy statement relating to the nomination of the Stockholder Nominee, including, without limitation, any statement in opposition to the nomination and any of the information provided pursuant to this Section 2.14.

(b) Maximum Number of Nominees.

(i) The maximum number of Stockholder Nominees that may be included in the Company’s proxy statement for an annual meeting of stockholders pursuant to this Section 2.14 shall not exceed the greater of (A) two or (B) 20 percent of the number of directors of the Company on the last day on which a Nomination Notice may be submitted pursuant to this Section 2.14 with respect to the annual meeting (rounded down to the nearest whole number) (the “Maximum Number”). The Maximum Number for a particular annual meeting shall be reduced by: (1) Stockholder Nominees whose nominations are subsequently withdrawn; (2) Stockholder Nominees who the board of directors itself decides to nominate for election at such annual meeting; and (3) the number of incumbent directors who had been Stockholder Nominees, or nominees of a stockholder pursuant to the advance notice requirements set forth in Section 2.11, at any of the preceding two annual meetings of stockholders and whose reelection at the upcoming annual meeting is being recommended by the board of directors. In the event that one or more vacancies for any reason occurs on the board of directors after the deadline set forth in Section 2.14(d) but before the date of the annual meeting, and the board of directors resolves to reduce the size of the board in connection therewith, the Maximum Number shall be calculated based on the number of directors as so reduced.

(ii) If the number of Stockholder Nominees pursuant to this Section 2.14 for any annual meeting of stockholders exceeds the Maximum Number then, promptly upon notice from the Company, each Nominating Stockholder will select one Stockholder Nominee for inclusion in the proxy statement until the Maximum Number is reached, going in order of the amount (largest to smallest) of shares of the Company’s common stock that each Nominating Stockholder disclosed as owned in its Nomination Notice, with the process repeated if the Maximum Number is not reached after each Nominating Stockholder has selected one Stockholder Nominee. Following such determination, whether before or after the mailing of the definitive proxy statement, if (A) a Nominating Stockholder becomes ineligible or withdraws its nomination, (B) a Stockholder Nominee becomes ineligible or unwilling to serve on the board of directors, or (C) a Stockholder Nominee is thereafter nominated by the board of directors, the Company: (1) shall not be required to include in its proxy statement or on any ballot or form of proxy the Stockholder Nominee (in the case of clause (A) or (B)) or any successor or replacement nominee proposed by the Nominating Stockholder or by any other Nominating Stockholder and (2) may otherwise communicate to its stockholders, including without limitation by amending or supplementing its proxy statement or ballot or form of proxy, that the Stockholder Nominee will not be included as a Stockholder Nominee in the proxy statement or on any ballot or form of proxy.




(c) Eligibility of Nominating Stockholder.

(i) An “Eligible Stockholder” is a person who has either (A) been a record holder of the shares of common stock of the Company used to satisfy the eligibility requirements in this Section 2.14(c) continuously for the three-year period specified in Section 2.14(c)(ii) below or (B) provides to the Secretary of the Company, within the time period referred to in Section 2.14(d), evidence of continuous ownership of such shares for such three-year period from one or more securities intermediaries in a form that the board of directors or its designee, acting in good faith, determines acceptable.

(ii) An Eligible Stockholder or group of up to 20 Eligible Stockholders may submit a nomination in accordance with this Section 2.14 only if the person or group (in the aggregate) has continuously owned at least the Minimum Number (as defined below) (as adjusted for any stock splits, stock dividends or similar events) of shares of the Company’s common stock throughout the three-year period preceding and including the date of submission of the Nomination Notice, and continues to own at least the Minimum Number of shares of the Company’s common stock through the date of the annual meeting. For purposes of qualifying as an Eligible Stockholder and satisfying the ownership requirements set forth in this Section 2.14(c)(ii), two or more funds that are (A) under common management and investment control, (B) under common management and funded primarily by the same employer, or (C) a “group of investment companies,” as such term is defined in Section 12(d)(1)(G)(ii) of the Investment Company Act of 1940, as amended, shall be treated as one stockholder or beneficial owner. Any group of funds whose shares are so aggregated shall, within five business days after the date of the Nomination Notice, submit to the Secretary of the Company at the Company’s principal executive office documentation that demonstrates that the funds satisfy the foregoing sentence, as determined by the board of directors or its designee acting in good faith, and such documentation shall be deemed part of the Nomination Notice for purposes of this Section 2.14. For the avoidance of doubt, in the event of a nomination by a group of Eligible Stockholders, any and all requirements and obligations for a given Eligible Stockholder that are set forth in this Section 2.14, including the minimum holding period, shall apply to each member of such group; provided, however, that the Minimum Number shall apply to the ownership of the group in the aggregate. Should any stockholder withdraw from a group of Eligible Stockholders at any time prior to the annual meeting of stockholders, the group of Eligible Stockholders shall only be deemed to own the shares held by the remaining members of the group.

(iii) The “Minimum Number” means three percent of the number of outstanding shares of the Company’s common stock as of the most recent date for which such amount is given in any filing by the Company with the SEC prior to the submission of the Nomination Notice.

(iv) For purposes of this Section 2.14, an Eligible Stockholder “owns” only those outstanding shares of the Company’s common stock as to which such Eligible Stockholder possesses both: (A) the full voting and investment rights pertaining to such shares and (B) the full economic interest in (including the opportunity for profit from and the risk of loss on) such shares; provided that the number of shares calculated in accordance with clauses (A) and (B) shall not include any shares (1) sold by such Eligible Stockholder or any of its affiliates in any transaction that has not been settled or closed, (2) borrowed by such Eligible Stockholder or any of its affiliates for any purpose or purchased by such Eligible Stockholder or any of its affiliates pursuant to an agreement to resell, or (3) subject to any



option, warrant, forward contract, swap, contract of sale, other derivative or similar agreement entered into by such Eligible Stockholder or any of its affiliates, whether any such instrument or agreement is to be settled with shares or with cash based on the notional amount or value of outstanding capital stock of the Company, in any such case which instrument or agreement has, or is intended to have, the purpose or effect of (x) reducing in any manner, to any extent or at any time in the future, such Eligible Stockholder’s or any of its affiliates’ full right to vote or direct the voting of any such shares, and/or (y) hedging, offsetting or altering to any degree any gain or loss arising from the full economic ownership of such shares by such Eligible Stockholder or any of its affiliates. An Eligible Stockholder “owns” shares held in the name of a nominee or other intermediary so long as the Eligible Stockholder retains the right to instruct how the shares are voted with respect to the election of directors and possesses the full economic interest in the shares. An Eligible Stockholder’s ownership of shares shall be deemed to continue during any period in which the Eligible Stockholder has delegated any voting power by means of a proxy, power of attorney or other similar instrument or arrangement that is revocable at any time by the Eligible Stockholder. An Eligible Stockholder’s ownership of shares shall be deemed to continue during any period in which the Eligible Stockholder has loaned such shares provided that the Eligible Stockholder has the power to recall such loaned shares on five days’ notice, the Eligible Stockholder recalls the loaned shares within five days of being notified that any of its Stockholder Nominees will be included in the Company’s proxy materials, and the Eligible Stockholder holds the recalled shares through the date of the annual meeting. The terms “owned,” “owning” and other variations of the word “own” shall have correlative meanings. Whether outstanding shares of the Company are “owned” for these purposes shall be determined by the board of directors or its designee acting in good faith. For purposes of this Section 2.14(d)(iii), the term “affiliate” or “affiliates” shall have the meaning ascribed thereto under the Exchange Act.

(v) No person may be a member of more than one group constituting a Nominating Stockholder, and if any person appears as a member of more than one group, it shall be deemed to be a member of only the group that has the largest ownership position as reflected in the Nomination Notice.

(d) Nomination Notice. To nominate a Stockholder Nominee pursuant to this Section 2.14, the Nominating Stockholder must submit to the Secretary of the Company at the Company’s principal executive office all of the following information and documents (collectively, the “Nomination Notice”) not less than 120 days nor more than 150 days prior to the anniversary of the date that the Company mailed its proxy statement for the prior year’s annual meeting; provided, however, that if (and only if) the annual meeting is not scheduled to be held within a period that commences 30 days before the first anniversary date of the preceding year’s annual meeting of stockholders and ends 30 days after the first anniversary date of the preceding year’s annual meeting of stockholders (an annual meeting date outside such period being referred to herein as an “Other Meeting Date”), the Nomination Notice shall be given in the manner provided herein by the later of the close of business on the date that is 180 days prior to such Other Meeting Date or the tenth day following the date such Other Meeting Date is first publicly announced or disclosed (in no event shall the adjournment or postponement of an annual meeting, or the announcement thereof, commence a new time period (or extend any time period) for the giving of the Nomination Notice):

(e) Exceptions.




(i) Notwithstanding anything to the contrary contained in this Section 2.14, the Company may omit from its proxy statement any Stockholder Nominee, and any information concerning such Stockholder Nominee (including a Nominating Stockholder’s statement in support), and in such case, no vote on such Stockholder Nominee will occur (notwithstanding that proxies in respect of such vote may have been received by the Company), and the Nominating Stockholder may not, after the last day on which a Nomination Notice would be timely, cure in any way any defect preventing the nomination of the Stockholder Nominee, if: (A) the Company receives a notice that a stockholder intends to nominate a candidate for director at the annual meeting pursuant to the advance notice requirements set forth in Section 2.11 without such stockholder’s notice expressly electing to have such director candidate included in the Company’s proxy statement pursuant to this Section 2.14; (B) the Nominating Stockholder or the designated lead group member, as applicable, or any qualified representative thereof, does not appear at the annual meeting to present the nomination submitted pursuant to this Section 2.14 or the Nominating Stockholder withdraws its nomination; (C) the board of directors, acting in good faith, determines that such Stockholder Nominee’s nomination or election to the board of directors would result in the Company violating or failing to be in compliance with these bylaws, the certificate of incorporation of the Company or any applicable state, federal or foreign law, rule or regulation, including the Stock Exchange Rules; (D) the Stockholder Nominee is not independent under the Stock Exchange Rules, any application rules of the SEC and any standards used by the board of directors in determining the independence of the Company’s directors, in each case as determined by the board of directors in good faith; (E) the Stockholder Nominee was nominated for election to the board of directors pursuant to this Section 2.14 at one of the Company’s two preceding annual meetings of stockholders and either (1) withdrew from or became ineligible or unavailable for election at such annual meeting or (2) did not receive a number of votes cast in favor of his or her election at least equal to 25% of the shares present in person or represented by proxy and entitled to vote in the election of directors; (F) the Stockholder Nominee has been, within the past three years, an officer or director of a competitor, as defined for purposes of Section 8 of the Clayton Antitrust Act of 1914, as amended; or (G) the Company is notified, or the board of directors or its designee acting in good faith determines, that a Nominating Stockholder has failed to continue to satisfy the eligibility requirements described in Section 2.14(c), any of the representations and warranties made in the Nomination Notice ceases to be true and accurate in all material respects (or omits a material fact necessary to make the statement made not misleading), the Stockholder Nominee becomes unwilling or unable to serve on the board of directors or any material violation or breach occurs of any of the obligations, agreements, representations or warranties of the Nominating Stockholder or the Stockholder Nominee under this Section 2.14.

(ii) Notwithstanding anything to the contrary contained in this Section 2.14, the Company may omit from its proxy statement, or may supplement or correct, any information, including all or any portion of the statement in support of the Stockholder Nominee included in the Nomination Notice, if the board of directors or its designee in good faith determines that: (A) such information is not true in all material respects or omits a material statement necessary to make the statements made not misleading; (B) such information directly or indirectly impugns the character, integrity or personal reputation of, or directly or indirectly makes charges concerning improper, illegal or immoral conduct or associations, without factual foundation, with respect to, any individual, corporation, partnership, association or other entity, organization or

ARTICLE THREE: DIRECTORS

3.1 Management. The business and property of the Company shall be managed by or under the direction of the board of directors. Subject to the restrictions imposed by law, the certificate of incorporation of the Company, or these bylaws, the board of directors may exercise all the powers of the Company.

3.2 Number; Election; Term; Qualification.

(a) The number of directors that shall constitute the entire board of directors shall be not less than three and not more than twenty-one. Within the limits above specified, the number of directors that shall constitute the whole board of directors shall from time to time be fixed exclusively by the board of directors by a resolution adopted by a majority of the whole board of directors serving at the time of that vote. Except as otherwise required by law or required or permitted by the certificate of incorporation of the Company or these bylaws, the directors shall be elected at an annual meeting of stockholders at which a quorum is present for terms expiring at the next annual meeting of stockholders. None of the directors needs to be a resident of the State of Delaware. Each director must have attained the age of majority. Each director must have been nominated by either the board of directors or the stockholders in accordance with the procedures set forth in the certificate of incorporation of the Company or in these bylaws or as otherwise required by law in order to be eligible for election as a director. As a condition of nomination or appointment (whether by the board of directors, stockholders or otherwise), each director nominee or appointee, whether or not an incumbent director, shall deliver an irrevocable, contingent resignation to the board of directors, in a form acceptable to the board of directors, to the attention of the Secretary of the Company, prior to the distribution of proxy solicitation materials for the meeting at which the director’s name will be submitted to the stockholders for election or prior to appointment. The director’s resignation shall become effective only if, and at such time that, he or she fails to receive a majority of the votes cast and the board of directors accepts the resignation, all as provided in Sections 3.2(b) and 3.2(c). A contingent resignation shall not be applicable at a meeting of stockholders for the election of directors if directors are to be elected by a plurality of votes as set forth in Section 3.2(b).
(b) Directors shall be elected by a majority of the votes cast by the holders of shares entitled to vote in the election of directors at a meeting of stockholders at which a quorum is present; provided, that if, as of the tenth (10th) day preceding the date that the Company first distributes its proxy materials for such meeting of its stockholders, the number of nominees exceeds the number of directors to be elected at such meeting, then the directors shall be elected by a plurality of the votes cast by the holders of shares entitled to vote in the election of directors at a meeting of stockholders at which a quorum is present. For purposes of this section, (i) a majority of the votes cast means that the number of votes cast “for” a director must exceed the number of votes cast “against” that director, and (ii) abstentions and broker nonvotes shall not be counted as votes cast either “for” or “against” any nominee for director. In an election in which directors will be elected by a majority of the votes cast, stockholders will be given the choice to cast votes



“for” or “against” the election of directors. In an election in which directors will be elected by a plurality of the votes cast, stockholders will be given the choice to cast “for” or “withhold” votes for the election of directors.

(c) The board of directors may, but shall not be obligated to, delegate to any existing committee of the board of directors, or may, but shall not be obligated to, designate a special committee of the board of directors and delegate to such special committee, the responsibility of making a recommendation to the board of directors as to whether to accept or reject any resignation tendered pursuant to Section 3.2(a) and whether to take other action. The board of directors will act on the tendered resignation within ninety (90) days after the date of the certification of the election results, taking into account any committee’s recommendation, if applicable, and will publicly disclose (by a press release, a report furnished to or filed with the SEC, or other broadly disseminated means of communication) its decision regarding the tendered resignation and, if the board of directors elects not to accept the resignation, the primary rationale for that decision. Any committee in making its recommendation, and the board of directors in making its decision, may consider any factors or other information it considers appropriate and relevant. If an incumbent director’s resignation is not accepted by the board of directors, that director shall continue to serve until the next annual meeting of stockholders at which he or she is to be re-elected to the board of directors in accordance with these bylaws after the non-acceptance of his or her resignation and until his or her successor shall have been elected and qualified or until his or her earlier death, retirement, resignation, or removal. If an incumbent director’s resignation is accepted by the board of directors, or if a nominee for director is not elected and the nominee is not an incumbent director, then the board of directors, in its sole discretion, may fill any resulting vacancy in accordance with the provisions of these bylaws or may decrease the size of the board of directors in accordance with the provisions of these bylaws.

3.3 Change in Number. No decrease in the number of directors constituting the entire board of directors shall have the effect of shortening the term of any incumbent director.
3.4 Removal. Any director or the entire board of directors may be removed, with or without cause, by the holders of a majority of the shares then entitled to vote at an election of directors,

3.5 Vacancies. Vacancies in the board of directors resulting from death, resignation, retirement, disqualification, removal from office or other cause and newly-created directorships resulting from any increase in the authorized number of directors shall be filled by a majority vote of the remaining directors then in office, though less than a quorum, who are designated to represent the same class or classes of stockholders that the vacant position, when filled, is to represent or by the sole remaining director (but not by the common stockholders except as required by law). Each director chosen to fill a vacancy in the board of directors shall hold office until the first meeting of stockholders held after his or her appointment for the purpose of electing directors and until his or her successor is elected and qualified or until his or her earlier death, resignation or removal from office. If there are no directors in office, an election of directors may be held in the manner provided by statute. Except as otherwise provided in these bylaws, when one or more directors shall resign from the board of directors, effective at a future date, a majority of the directors then in office, including those who have so resigned, who are designated to represent the same class or classes or series of stockholders that the position being vacated represents shall have the power to fill such vacancy or vacancies, the vote thereon to take effect when such resignation or resignations shall become effective, and each director so chosen shall hold office as provided in these bylaws with respect to the filling of other vacancies.




3.6 Meetings of Directors. The directors may hold their meetings and may have an office and keep the books of the Company, except as otherwise provided by statute, in such place or places within or without the State of Delaware as the board of directors may from time to time determine or as shall be specified in the notice of such meeting or duly executed waiver of notice of such meeting.

3.7 First Meeting. Each newly elected board of directors may hold its first meeting for the purpose of organization and the transaction of business, if a quorum is present, immediately after and at the same place as the annual meeting of stockholders, and no notice of such meeting shall be necessary.

3.9 Special Meetings. Special meetings of the board of directors shall be held whenever called by the Chairman of the Board, the Chief Executive Officer, or any director.

3.10 Notice. The Secretary shall give notice of each special meeting to each director at least 24 hours before the meeting. Notice of any such meeting need not be given to any director who shall, either before or after the meeting, submit a signed waiver of notice or who shall attend such meeting without protesting, prior to or at its commencement, the lack of notice to the director. Neither the business to be transacted at, nor the purpose of, any regular or special meeting of the board of directors need be specified in the notice or waiver of notice of such meeting.

3.11 Quorum; Majority Vote. At all meetings of the board of directors, a majority of the directors fixed in the manner provided in these bylaws shall constitute a quorum for the transaction of business. If at any meeting of the board of directors there be less than a quorum present, a majority of those present or any director solely present may adjourn the meeting from time to time without further notice. Unless the act of a greater number is required by law, the certificate of incorporation of the Company, or these bylaws, the act of a majority of the directors present at a meeting at which a quorum is in attendance shall be the act of the board of directors. At any time that the certificate of incorporation of the Company provides that directors elected by the holders of a class or series of stock shall have more or less than one vote per director on any matter, every reference in these bylaws to a majority or other proportion of directors shall refer to a majority or other proportion of the votes of such directors.

3.12 Procedure. At meetings of the board of directors, business shall be transacted in such order as from time to time the board of directors may determine. The Chairman of the Board, if such office has been filled, shall preside at all meetings of the board of directors. If such position has not been filled, or if the Chairman of the Board is absent or otherwise unable to act, the Chief Executive Officer shall preside unless otherwise determined by the board of directors. The Secretary of the Company shall act as the secretary of each meeting of the board of directors unless the board of directors appoints another person to act as secretary of the meeting. The board of directors shall keep regular minutes of its proceedings which shall be placed in the minute book of the Company.

3.13 Presumption of Assent. A director of the Company who is present at the meeting of the board of directors or at any committee of the board of directors at which action is taken shall be presumed to have assented to the action unless his or her dissent shall be entered in the minutes of the meeting or unless he or she shall file his or her written dissent to such action with the person acting as secretary of the meeting before the adjournment thereof. Such right to dissent shall not apply to a director who voted in favor of such action.




3.14 Compensation. The board of directors shall have the authority to fix the compensation, including fees and reimbursement of expenses, paid to directors for attendance at regular or special meetings of the board of directors or any committee thereof; provided, that nothing contained herein shall be construed to preclude any director from serving the Company in any other capacity or receiving compensation therefor.

EXHIBIT 4.15
DESCRIPTION OF COMMON STOCK

General

Pioneer Natural Resources Company (“Pioneer”) is incorporated in the State of Delaware. The rights of Pioneer’s common stock are generally covered by Delaware law and Pioneer’s certificate of incorporation and bylaws. The terms of Pioneer’s common stock are therefore subject to Delaware law, including the Delaware General Corporation Law (the “DGCL”), and the common and constitutional law of Delaware.

This exhibit describes the general terms of Pioneer’s common stock, including preferred stock that may be issued without the vote of Pioneer’s common stock. This is a summary and does not purport to be complete. References in this exhibit to Pioneer’s certificate of incorporation and bylaws mean Pioneer’s certificate of incorporation and bylaws as each has been amended and restated from time to time. Pioneer’s certificate of incorporation and bylaws as they exist on the date of this Annual Report on Form 10-K are incorporated by reference or filed as an exhibit to the Annual Report on Form 10-K of which this exhibit is a part, and amendments or restatements of each will be filed with the Securities and Exchange Commission (the “SEC”) in future periodic or current reports in accordance with SEC rules.

For more detailed information about the rights of Pioneer’s common stock, you should refer to Pioneer’s certificate of incorporation and bylaws and the applicable provisions of Delaware law, including the DGCL, for additional information.

Authorized Capital Stock

Pioneer’s authorized capital stock consists of 600,000,000 shares of stock, including:

500,000,000 shares of common stock, $0.01 par value per share; and

100,000,000 shares of preferred stock, $0.01 par value per share, including 500,000 shares that are designated (but not issued) as Series A Junior Participating Preferred Stock.

Common Stock

Holders of Pioneer’s common stock are entitled to one vote per share with respect to each matter submitted to a vote of Pioneer’s stockholders, subject to voting rights that may be established for shares of Pioneer’s preferred stock, if any. Except as may be provided in connection with Pioneer’s preferred stock or as otherwise may be required by law or Pioneer’s certificate of incorporation, Pioneer’s common stock is the only capital stock entitled to vote in the election of directors. Pioneer’s common stock does not have cumulative voting rights.

Subject to the rights of holders of Pioneer’s preferred stock, if any, holders of Pioneer’s common stock are entitled to receive dividends lawfully declared by the board of directors of Pioneer (the “Pioneer Board”). If Pioneer liquidates, dissolves or winds up its business, whether voluntarily or involuntarily, holders of Pioneer’s common stock will be entitled to receive any assets available for distribution to Pioneer’s stockholders after Pioneer has paid or set apart for payment the amounts necessary to satisfy any preferential or participating rights to which the holders of each outstanding series of preferred stock are entitled by the express terms of the series of preferred stock.

The outstanding shares of Pioneer’s common stock are fully paid and nonassessable. Pioneer’s common stock does not have any preemptive, subscription or conversion rights. Pioneer may issue additional shares of its authorized common stock as authorized by the Pioneer Board from time to time, without stockholder approval, except as may be required by applicable stock exchange requirements.

Preferred Stock





This section describes the general terms and provisions of Pioneer’s preferred stock. If Pioneer designates or issues a new series of preferred stock, it will file a copy of the certificate of designations that contains the terms of that series with the SEC. Each certificate of designations will establish the number of shares included in a designated series and fix the designation, powers, privileges, preferences and rights of the shares of each series as well as any applicable qualifications, limitations or restrictions.

The Pioneer Board has been authorized to provide for the issuance of shares of Pioneer’s preferred stock in multiple series without the approval of common stockholders. With respect to each series of Pioneer’s preferred stock, the Pioneer Board has the authority to fix the terms of the series, including, without limitation, the following:

the designation of the series;

the number of shares within the series;

whether dividends are cumulative and, if cumulative, the dates from which dividends are cumulative;

the rate of any dividends, any conditions upon which dividends are payable, and the dates of payment of dividends;

whether the shares are redeemable, the redemption price and the terms of redemption;

the amount payable to a holder of such shares for each share owned if Pioneer dissolves or liquidates;

whether the shares are convertible or exchangeable, the price or rate of conversion or exchange, and the applicable terms and conditions;

any restrictions on issuance of shares in the same series or any other series;

voting rights applicable to the series of preferred stock; and

any other rights, preferences or limitations of the series.

A preferred stockholder’s rights with respect to that holder’s shares of preferred stock will be subordinate to the rights of Pioneer’s general creditors. Shares of Pioneer’s preferred stock that Pioneer issues will be fully paid and nonassessable and will not be entitled to preemptive rights unless specified in the applicable certificate of designations.

Pioneer’s ability to issue preferred stock, or rights to purchase such shares, could discourage an unsolicited acquisition proposal. For example, Pioneer could impede a business combination by issuing a series of preferred stock containing class voting rights that would enable the holders of such preferred stock to block a business combination transaction. Alternatively, Pioneer could facilitate a business combination transaction by issuing a series of preferred stock having sufficient voting rights to provide a required percentage vote of the stockholders. Additionally, under certain circumstances, Pioneer’s issuance of preferred stock could adversely affect the voting power of the holders of Pioneer’s common stock. Although the Pioneer Board is required to make any determination to issue any preferred stock based on its judgment as to the best interests of Pioneer and its common stockholders, the Pioneer Board could act in a manner that would discourage an acquisition attempt or other transaction that some, or a majority, of Pioneer’s stockholders might believe to be in their best interests or in which stockholders might receive a premium for their stock over prevailing market prices of such stock. The Pioneer Board does not at present intend to seek stockholder approval prior to any issuance of currently authorized stock, unless otherwise required by law or applicable stock exchange requirements.

Limitation on Directors’ Liability





Pioneer’s certificate of incorporation provides, as authorized by Section 102(b)(7) of the DGCL, that a director of Pioneer will not be personally liable to Pioneer or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability:

for any breach of the director’s duty of loyalty to Pioneer or its stockholders;

for acts or omission not in good faith or that involve intentional misconduct or a knowing violation of law;

for unlawful payments of dividends or unlawful stock repurchases or redemptions as provided in Section 174 of the DGCL; or

for any transaction from which the director derived an improper personal benefit.

The inclusion of this provision in Pioneer’s certificate of incorporation may have the effect of reducing the likelihood of derivative litigation against directors and may discourage or deter stockholders or management from bringing a lawsuit against directors for breach of their duty of care, even though such an action, if successful, might otherwise have benefited Pioneer and its stockholders.

Section 203 of the Delaware General Corporation Law

Section 203 of the DGCL prohibits a defined set of transactions between a Delaware corporation, such as Pioneer, and an “interested stockholder.” An interested stockholder is defined as a person who, together with any affiliates or associates of such person, beneficially owns, directly or indirectly, 15% or more of the outstanding voting shares of a Delaware corporation. This provision may prohibit business combinations between an interested stockholder and a corporation for a period of three years after the date the interested stockholder becomes an interested stockholder. The term “business combination” is broadly defined to include a broad array of transactions, including mergers, consolidations, sales or other dispositions of assets having a total value in excess of 10% of the consolidated assets of the corporation or all of the outstanding stock of the corporation, and some other transactions that would increase the interested stockholder’s proportionate share ownership in the corporation.

This prohibition is effective unless:

the business combination or the transaction that resulted in the stockholder becoming an interested stockholder is approved by the corporation’s board of directors prior to the time the interested stockholder becomes an interested stockholder;

the interested stockholder acquired at least 85% of the voting stock of the corporation, other than stock held by directors who are also officers or by qualified employee stock plans, in the transaction in which it becomes an interested stockholder; or

the business combination is approved by a majority of the corporation’s board of directors and by the affirmative vote of 66 23% of the outstanding voting stock that is not owned by the interested stockholder.

Certain Certificate of Incorporation and Bylaws Provisions

Advance Notice for Stockholder Proposals and Director Nominations

Pioneer’s certificate of incorporation and its bylaws contain provisions requiring that advance notice be delivered to Pioneer of any business to be brought by a stockholder before an annual meeting of stockholders and providing for certain procedures to be followed by stockholders in nominating persons for election to the Pioneer Board. Generally, the advance notice provisions provide that the stockholder must give written notice to Pioneer’s Secretary not less than 60 days before the scheduled date of the annual meeting of Pioneer’s stockholders or, if later, ten days after the first public notice of the annual meeting is sent to Pioneer’s stockholders. The notice must set forth specific information regarding that stockholder and that business or director nominee, as described in Pioneer’s




certificate of incorporation and bylaws. This requirement is in addition to those set forth in the regulations adopted by the SEC under the Securities Exchange Act of 1934.

Proxy Access

Pioneer’s bylaws permit a stockholder, or a group of up to 20 stockholders (with funds having specified relationships constituting a single stockholder), owning 3% or more of Pioneer’s outstanding common stock continuously for at least three years to nominate and include in Pioneer’s proxy materials director candidates constituting up to 20% of the board of directors (rounded down to the nearest whole number) or two directors, whichever is greater, provided that the stockholder(s) and the nominee(s) satisfy the requirements specified in the bylaws and subject to the other terms and conditions set forth in the bylaws.

Election of Directors; Majority Voting in Uncontested Elections

Pioneer’s certificate of incorporation and its bylaws provide that, subject to any rights of holders of preferred stock to elect one or more directors, the number of directors shall not be fewer than three or more than 21.

Pioneer’s certificate of incorporation provides that all directors are to be elected annually. Pioneer’s bylaws provide for the election of directors by the majority of votes cast by stockholders in uncontested elections and by plurality vote in contested elections. As a condition to being nominated, each nominee for director is required to submit an irrevocable letter of resignation that becomes effective if the nominee does not receive a majority of the votes cast in an uncontested election and the Board decides to accept the resignation. If a nominee who is currently serving as a director does not receive a majority of the votes cast for his or her election in an uncontested election, the Board will act on the tendered resignation within 90 days after the date of the certification of the election results. If the resignation is not accepted, the Board will publicly disclose its decision and its primary rationale, and the director will continue to serve as a director until his or her successor is elected and qualified or until his or her earlier resignation or removal. If the Board accepts the resignation, the Board may fill the vacancy in accordance with Pioneer’s bylaws or may decrease the size of the Board.

Pioneer’s certificate of incorporation and its bylaws provide that vacancies in the board of directors resulting from death, resignation, retirement, disqualification, removal from office or other cause and newly created directorships resulting from any increase in the authorized number of directors shall be filled by a majority vote of the remaining directors then in office, though less than a quorum, or by the sole remaining director.

No Stockholder Action by Written Consent

Pioneer’s certificate of incorporation provides that stockholders may not act by written consent in lieu of a meeting.

Special Meetings of Stockholders

Special meetings of the stockholders may be called by the Pioneer Board, but may not be called by Pioneer’s stockholders.

Fair Price Provision

Pioneer’s certificate of incorporation also contains a “fair price” provision that applies to certain business combination transactions involving any person or group that beneficially owns at least 10% of the aggregate voting power of Pioneer’s outstanding capital stock, referred to as a “related person.” The “fair price” provision requires the affirmative vote of the holders of:

at least 80% of the voting power of Pioneer’s outstanding capital stock entitled to vote generally in the election of directors, and

at least 66 23% of the voting power of Pioneer’s outstanding capital stock entitled to vote generally in the election of directors that is not beneficially owned by the related person





to approve certain transactions between the related person and Pioneer or its subsidiaries, including any merger, consolidation or share exchange, any sale, lease, exchange, pledge or other disposition of Pioneer’s assets or its subsidiaries having a fair market value of at least $10 million, any transfer or issuance of Pioneer’s securities or its subsidiaries’ securities, any adoption of a plan or proposal by Pioneer of its voluntary liquidation or dissolution, certain reclassifications of Pioneer’s securities or recapitalizations or certain other transactions, in each case involving the related person.

This voting requirement will not apply to certain transactions, including:

any transaction in which the consideration to be received by the holders of each class or series of capital stock is:

the same in form and amount as that paid in a tender offer in which the related person acquired at least 50% of the outstanding shares of such class or series and which was consummated not more than one year earlier; or

not less in amount than the highest per share price paid by the related person for shares of such class or series; and

any transaction approved by Pioneer’s continuing directors.

This provision could have the effect of delaying or preventing change in control in a transaction or series of transactions that do not satisfy the “fair price” criteria.

Exclusive Forum for Adjudication of Disputes

Pioneer’s bylaws provide that unless Pioneer consents in writing to the selection of an alternative forum, the Delaware Court of Chancery (or if the Court of Chancery does not have jurisdiction, the federal district court for the District of Delaware) shall be the sole and exclusive forum for (a) any derivative action or proceeding brought on behalf of Pioneer, (b) any action asserting a claim of breach of a fiduciary duty owed by any director, officer, other employee or agent or stockholder of Pioneer to Pioneer or Pioneer’s stockholders, (c) any action against Pioneer arising pursuant to any provision of the DGCL or as to which the DGCL confers jurisdiction on the Delaware Court of Chancery, or (d) any action against Pioneer or any director, officer, other employee or agent of Pioneer asserting a claim governed by the internal affairs doctrine, including, without limitation, any action to interpret, apply, enforce or determine the validity of the certificate of incorporation of Pioneer or Pioneer’s bylaws, in each case subject to such Court of Chancery (or if the Court of Chancery does not have jurisdiction, the federal district court for the District of Delaware) having personal jurisdiction over the indispensable parties named as defendants therein. Pioneer’s bylaws also provide that, unless Pioneer consents in writing to the selection of an alternative forum, the federal district courts of the United States of America shall be the sole and exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act of 1933.

Although Pioneer believes these provisions benefit Pioneer by providing increased consistency in the application of Delaware law or U.S. securities laws in the types of lawsuits to which they apply, the provisions may have the effect of discouraging lawsuits against Pioneer’s directors and officers or against Pioneer. Although Pioneer’s bylaws contain the choice of forum provisions described above, it is possible that a court could rule that either or both of the provisions are inapplicable for a particular claim or action or are unenforceable.

Amendments

In addition to any other vote required by law, the provisions of Pioneer’s certificate of incorporation relating to the limitation of actions taken by written consent and the “fair price” provision may be amended only by the affirmative vote of the holders of at least 80% of the aggregate voting power of Pioneer’s outstanding capital stock entitled to vote generally in the election of directors.





Pioneer’s bylaws may be amended by the Pioneer Board or by the affirmative vote of the holders of at least 6623% of the aggregate voting power of Pioneer’s outstanding capital stock entitled to vote in the election of directors.

Potential Anti-Takeover Effect

Certain of the foregoing provisions of Pioneer’s certificate of incorporation and Pioneer’s bylaws, together with the provisions of Section 203 of the DGCL, could have the effect of delaying, deferring or preventing a change in control or the removal of existing management, of deterring potential acquirors from making an offer to Pioneer’s stockholders and of limiting any opportunity to realize premiums over prevailing market prices for Pioneer’s common stock in connection therewith. This could be the case notwithstanding that a majority of Pioneer’s stockholders might benefit from such a change in control or offer.

Transfer Agent and Registrar

Continental Stock Transfer & Trust Company serves as the registrar and transfer agent for Pioneer’s common stock.

Stock Exchange Listing

Pioneer’s common stock is listed on the New York Stock Exchange. The trading symbol for Pioneer’s common stock is “PXD.”

EXHIBIT 10.4 2H

PIONEER NATURAL RESOURCES COMPANY

INDEMNIFICATION AGREEMENT

This Agreement (“Agreement”) is made and entered into as of the 12th day of January, 2021, by and between Pioneer Natural Resources Company, a Delaware corporation (the “Company”), and A.R. Alameddine (“Indemnitee”).

RECITALS

A. Highly competent and experienced persons are reluctant to serve corporations as directors, executive officers or in other capacities unless they are provided with adequate protection through insurance and indemnification against claims and actions against them arising out of their service to and activities on behalf of the Company.

B. The Board of Directors of the Company (the “Board”) has determined that the inability to attract and retain such persons would be detrimental to the best interests of the Company and its stockholders and that the Company should act to assure such persons that there will be increased certainty of such protection in the future.

C. The Board has also determined that it is reasonable, prudent and necessary for the Company, in addition to purchasing and maintaining directors’ and officers’ liability insurance (or otherwise providing for adequate arrangements of self-insurance), to contractually obligate itself to indemnify, hold harmless, and exonerate and to advance expenses on behalf of such persons to the fullest extent permitted by applicable law so that they will serve or continue to serve the Company free from undue concern that they will not be adequately protected.

D. Indemnitee is willing to serve, to continue to serve and to take on additional service for or on behalf of the Company on the condition that Indemnitee be so indemnified to the fullest extent permitted by law.

E. Article Twelfth of the Amended and Restated Certificate of Incorporation of the Company (as it may be amended or restated from time to time, the “Certificate of Incorporation”) provides for indemnification of directors and officers to the fullest extent permitted by law.

F. This Agreement is supplemental to and in furtherance of the Certificate of Incorporation and any resolutions adopted pursuant thereto, as well as any rights of Indemnitee under any directors’ and officers’ liability insurance policy, and this Agreement shall not be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee thereunder.

In consideration of the foregoing and the mutual covenants herein contained, and other good and valuable consideration, the sufficiency and receipt of which are hereby acknowledged, the parties hereby agree as follows:




ARTICLE I

Certain Definitions

As used herein, the following words and terms shall have the following respective meanings (whether singular or plural):

“Change in Control” means the occurrence of any of the following events:

(i) The acquisition by any Person of beneficial ownership (within the meaning of Rule 13d-3 promulgated under the Exchange Act) of 40% or more of either (x) the then outstanding shares of common stock of the Company (the “Outstanding Company Common Stock”) or (y) the combined voting power of the then outstanding Voting Securities of the Company (the “Outstanding Company Voting Securities”); provided, however, that for purposes of this Subparagraph (i), any acquisition by any corporation pursuant to a transaction that complies with clauses (A), (B) and (C) of paragraph (iii) below shall not constitute a Change of Control; or

(iv) Approval by the stockholders of the Company of a complete liquidation or dissolution of the Company.

ARTICLE II

Services by Indemnitee

Indemnitee is serving as a director of the Company. Indemnitee may from time to time also agree to serve, as the Company may request from time to time, in another capacity for the Company (including an officer position) or as a director, officer, partner, member, venturer, proprietor, trustee, employee, agent, fiduciary or similar functionary of another foreign or domestic corporation, partnership, joint venture, limited liability company, sole proprietorship, trust, employee benefit plan or other enterprise. Indemnitee and the Company each acknowledge that they have entered into this Agreement as a means of inducing Indemnitee to serve, or continue to serve, the Company in such capacities. Indemnitee may at any time and for any reason resign from such position or positions (subject to any other contractual obligation or any obligation imposed by operation of law). The Company shall have no obligation under this Agreement to continue Indemnitee in any such position or positions. This Agreement shall continue in full force and effect after Indemnitee has ceased to serve as an officer or director of the Company as provided in Section 7.5.

ARTICLE III

Indemnification

Section 3.1    General. Subject to the provisions set forth in Article IV, the Company shall indemnify, and advance Expenses to, Indemnitee as set forth in this Article III to the fullest extent permitted by applicable law in effect on the date hereof and to such greater extent as applicable law may hereafter from time to time permit. The other provisions set forth in this Agreement are provided in addition to and as a means of furtherance and implementation of, and not in limitation of, the obligations expressed in this Article III. No requirement, condition to or limitation of any right to indemnification or to advancement of Expenses under this Article III shall in any way limit the rights of Indemnitee under Article VII.

Section 3.2    Indemnification in Third-Party Proceedings. To the fullest extent permitted by applicable law in effect on the date hereof and to such greater extent as applicable law may hereafter from time to time permit, the Company shall indemnify, hold harmless, and exonerate Indemnitee if, by reason of anything done or not done by Indemnitee in, or by reason of, Indemnitee’s Corporate Status, Indemnitee is, was or becomes, or is threatened to be made, a party to, or witness or other participant in, any Proceeding, other than a Proceeding by or in the right of the Company to procure a judgment in its favor. Pursuant to this Section 3.2, Indemnitee shall be indemnified against any and all Expenses, judgments, penalties (including excise or similar taxes), fines and amounts paid in settlement (including all interest, assessments and other



charges paid or payable in connection with or in respect of any such Expenses, judgments, penalties, fines and amounts paid in settlement) actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection with such Proceeding or any Claim, issue or matter therein. Notwithstanding the foregoing, the obligations of the Company under this Section 3.2 shall be subject to the condition that no determination (which, in any case in which Independent Counsel is involved, shall be in a form of a written opinion) shall have been made pursuant to Article IV that Indemnitee would not be permitted to be indemnified under applicable law. Nothing in this Section 3.2 shall limit the benefits of Section 3.1, Section 3.4 or any other Section hereunder.

Section 3.3    Indemnification in Proceedings By or In the Right of the Company. To the fullest extent permitted by applicable law in effect on the date hereof and to such greater extent as applicable law may hereafter from time to time permit, the Company shall indemnify, hold harmless, and exonerate Indemnitee if, by reason of anything done or not done by Indemnitee in, or by reason of, Indemnitee’s Corporate Status, Indemnitee is, was or becomes, or is threatened to be made, a party to, or witness or other participant in, any Proceeding by or in the right of the Company to procure a judgment in its favor. Pursuant to this Section 3.3, Indemnitee shall be indemnified against any and all Expenses and amounts paid in settlement (including all interest, assessments and other charges paid or payable in connection with or in respect of any such Expenses and amounts paid in settlement) actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection with such Proceeding or any Claim, issue or matter therein. No indemnification, hold harmless or exoneration for Expenses or amounts paid in settlement shall be made under this Section 3.3 in respect of any claim, issue or matter as to which Indemnitee shall have been finally adjudged by a court to be liable to the Company, unless and only to the extent that any court in which the Proceeding was brought or the Delaware Court shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, Indemnitee is fairly and reasonably entitled to indemnification, to be held harmless or to exoneration. Notwithstanding the foregoing, the obligations of the Company under this Section 3.3 shall be subject to the condition that no determination (which, in any case in which Independent Counsel is involved, shall be in a form of a written opinion) shall have been made pursuant to Article IV that Indemnitee would not be permitted to be indemnified under applicable law. Nothing in this Section 3.3 shall limit the benefits of Section 3.1, Section 3.4 or any other Section hereunder.

Section 3.4    Advancement of Expenses. The Company shall pay all Expenses reasonably incurred by, or in the case of retainers to be incurred by, or on behalf of Indemnitee (or, if applicable, reimburse Indemnitee for any and all Expenses reasonably incurred by Indemnitee and previously paid by Indemnitee) in connection with any Claim or Proceeding, whether brought by or in the right of the Company or otherwise, in advance of any determination respecting entitlement to indemnification pursuant to Article IV hereof (and shall continue to pay such Expenses after such determination and until it shall ultimately be determined (in a final adjudication by a court from which there is no further right of appeal or in a final adjudication of an arbitration pursuant to Section 5.1 if Indemnitee elects to seek such arbitration) that Indemnitee is not entitled to be indemnified by the Company against such Expenses) within 10 days after the receipt by the Company of (a) a written request from Indemnitee requesting such payment or payments from time to time, whether prior to or after final disposition of such Claim or Proceeding, and (b) a written affirmation from Indemnitee of Indemnitee’s good faith belief



that Indemnitee has met the standard of conduct necessary for Indemnitee to be permitted to be indemnified under applicable law. Any such payment by the Company is referred to in this Agreement as an “Expense Advance.” In connection with any request for an Expense Advance, if requested by the Company, Indemnitee or Indemnitee’s counsel shall also submit an affidavit stating that the Expenses incurred were, or in the case of retainers to be incurred are, reasonably incurred. Any dispute as to the reasonableness of the incurrence of any Expense shall not delay an Expense Advance by the Company, and the Company agrees that any such dispute shall be resolved only upon the disposition or conclusion of the underlying Claim against Indemnitee. Indemnitee hereby undertakes and agrees that Indemnitee will reimburse and repay the Company without interest for any Expense Advances to the extent that it shall ultimately be determined (in a final adjudication by a court from which there is no further right of appeal or in a final adjudication of an arbitration pursuant to Section 5.1 if Indemnitee elects to seek such arbitration) that Indemnitee is not entitled to be indemnified by the Company against such Expenses. Indemnitee shall not be required to provide collateral or otherwise secure the undertaking and agreement described in the prior sentence. The Company shall make all Expense Advances pursuant to this Section 3.4 without regard to the financial ability of Indemnitee to make repayment and without regard to the prospect of whether Indemnitee may ultimately be found to be entitled to indemnification under the provisions of this Agreement.

Section 3.5    Indemnification for Additional Expenses. The Company shall indemnify Indemnitee against any and all costs and expenses (of the types described in the definition of Expenses in Article I) and, if requested by Indemnitee, shall (within two business days of that request) advance those costs and expenses to Indemnitee, that are incurred by Indemnitee in connection with any claim asserted against, or action brought by, Indemnitee for (i) indemnification or an Expense Advance by the Company under this Agreement or any other agreement or provision of the Company’s Certificate of Incorporation or the Company’s Fifth Amended and Restated Bylaws (as they may be amended or restated from time to time, the “Bylaws”) now or hereafter in effect relating to any Claim or Proceeding, (ii) recovery under any directors’ and officers’ liability insurance policies maintained by the Company, or (iii) enforcement of, or claims for breaches of, any provision of this Agreement, in each of the foregoing situations regardless of whether Indemnitee ultimately is determined to be entitled to that indemnification, Expense Advance payment, insurance recovery, enforcement, or damage claim, as the case may be, and regardless of whether the nature of the proceeding with respect to such matters is judicial, by arbitration, or otherwise.

Section 3.6    Indemnification for Expenses of a Party Who Is Wholly or Partly Successful. Notwithstanding any other provisions of this Agreement, to the extent that Indemnitee was or is, by reason of Indemnitee’s Corporate Status, a party to (or a participant in) and is successful, on the merits or otherwise, in any Proceeding or in defense of any claim, issue or matter therein, in whole or in part, the Company shall, to the fullest extent permitted by applicable law, indemnify, hold harmless and exonerate Indemnitee against all Expenses actually and reasonably incurred by Indemnitee in connection therewith. If Indemnitee is not wholly successful in such Proceeding but is successful, on the merits or otherwise, as to one or more but less than all claims, issues or matters in such Proceeding, the Company shall, to the fullest extent permitted by applicable law, indemnify, hold harmless and exonerate Indemnitee against all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection with each successfully resolved claim, issue or matter. If Indemnitee is not wholly



successful in such Proceeding, the Company also shall, to the fullest extent permitted by applicable law, indemnify, hold harmless and exonerate Indemnitee against all Expenses reasonably incurred in connection with a claim, issue or matter related to any claim, issue or matter on which Indemnitee was successful. For purposes of this Section 3.6 and without limitation, the termination of any claim, issue or matter in such a Proceeding by dismissal, with or without prejudice, shall be deemed to be a successful result as to such claim, issue or matter.

Section 3.7    Partial Indemnity. If Indemnitee is entitled under any provision of this Agreement to indemnification by the Company for some or a portion of the Expenses, judgments, fines, penalties, and amounts paid in settlement of a Claim or Proceeding but not, however, for all of the total amount thereof, the Company shall nevertheless indemnify Indemnitee for the portion thereof to which Indemnitee is entitled.

ARTICLE IV

Procedure for Determination of Entitlement
to Indemnification

Section 4.1    Request by Indemnitee. To obtain indemnification under this Agreement, Indemnitee shall submit to the Company a written request in accordance with Section 7.6, including therein or therewith such documentation and information as is reasonably available to Indemnitee and is reasonably necessary to determine whether and to what extent Indemnitee is entitled to indemnification. The Secretary or an Assistant Secretary of the Company shall, promptly upon receipt of such a request for indemnification, advise the Board in writing that Indemnitee has requested indemnification. Nevertheless, any failure of Indemnitee to provide a request to the Company, or to provide such a request timely, shall not relieve the Company of any obligation that it may have to Indemnitee hereunder except, and to the extent that, such failure actually and materially prejudices the interests of the Company.

Section 4.2    Determination of Request. Upon written request by Indemnitee for indemnification pursuant to the first sentence of Section 4.1 hereof, a determination, if required by applicable law, with respect to whether Indemnitee is permitted under applicable law to be indemnified shall be made, in accordance with the terms of Section 4.5, in the specific case as follows:
(a)    If a Potential Change in Control or a Change in Control shall have occurred, by Independent Counsel (selected in accordance with Section 4.3) in a written opinion to the Board and Indemnitee, unless Indemnitee shall request that such determination be made by the Board, or a committee of the Board, in which case by the person or persons or in the manner provided for in clause (i) or (ii) of paragraph (b) below; or

(b)    If a Potential Change in Control or a Change in Control shall not have occurred, (i) by the Board by a majority vote of the Disinterested Directors even though less than a quorum of the Board, (ii) by a majority vote of a committee solely of two or more Disinterested Directors designated to act in the matter by a majority vote of all Disinterested Directors even though less than a quorum of the Board, (iii) by Independent Counsel selected by the Board or a committee of the Board by a vote as set forth in



clauses (i) or (ii) of this paragraph (b), or if such vote is not obtainable or such a committee cannot be established, by a majority vote of all directors, or (iv) if Indemnitee and the Company agree, by the stockholders of the Company in a vote that excludes the shares held by directors who are not Disinterested Directors.

If it is so determined that Indemnitee is permitted to be indemnified under applicable law, payment to Indemnitee shall be made within 10 days after such determination. Nothing contained in this Agreement shall require that any determination be made under this Section 4.2 prior to the disposition or conclusion of a Claim or Proceeding against Indemnitee; provided, however, that Expense Advances shall continue to be made by the Company pursuant to, and to the extent required by, the provisions of Article III. Indemnitee shall reasonably cooperate with the person or persons making such determination with respect to Indemnitee’s entitlement to indemnification, including providing to such person upon reasonable advance request any documentation or information that is not privileged or otherwise protected from disclosure and that is reasonably available to Indemnitee and reasonably necessary to such determination. Any costs or expenses (including attorneys’ fees and disbursements) incurred by Indemnitee in so cooperating with the person or persons making such determination shall be borne by the Company (irrespective of the determination as to Indemnitee’s entitlement to indemnification), and the Company shall indemnify and hold harmless Indemnitee therefrom.

Section 4.3    Independent Counsel. If a Potential Change in Control or a Change in Control shall not have occurred and the determination of entitlement to indemnification is to be made by Independent Counsel, the Independent Counsel shall be selected by (a) a majority vote of the Disinterested Directors, even though less than a quorum of the Board or (b) if there are no Disinterested Directors, by a majority vote of the Board, and the Company shall give written notice to Indemnitee, within 10 days after receipt by the Company of Indemnitee’s request for indemnification, specifying the identity and address of the Independent Counsel so selected. If a Potential Change in Control or a Change in Control shall have occurred and the determination of entitlement to indemnification is to be made by Independent Counsel, the Independent Counsel shall be selected by Indemnitee, and Indemnitee shall give written notice to the Company, within 10 days after submission of Indemnitee’s request for indemnification, specifying the identity and address of the Independent Counsel so selected (unless Indemnitee shall request that such selection be made by the Disinterested Directors or a committee of the Board, in which event the Company shall give written notice to Indemnitee within 10 days after receipt of Indemnitee’s request for the Board or a committee of the Disinterested Directors to make such selection, specifying the identity and address of the Independent Counsel so selected). In either event, (i) such notice to Indemnitee or the Company, as the case may be, shall be accompanied by a written affirmation of the Independent Counsel so selected that it satisfies the requirements of the definition of “Independent Counsel” in Article I and that it agrees to serve in such capacity and (ii) Indemnitee or the Company, as the case may be, may, within seven days after such written notice of selection shall have been given, deliver to the Company or to Indemnitee, as the case may be, a written objection to such selection. Any objection to the selection of Independent Counsel pursuant to this Section 4.3 may be asserted only on the ground that the Independent Counsel so selected does not meet the requirements of the definition of “Independent Counsel” in Article I, and the objection shall set forth with particularity the factual basis of such assertion. If such written objection is timely made, the Independent Counsel so selected may not serve as Independent Counsel unless and until a court of competent jurisdiction (the “Court”) has



determined that such objection is without merit or such objection is withdrawn. In the event of a timely written objection to a choice of Independent Counsel, the party originally selecting the Independent Counsel shall have seven days to make an alternate selection of Independent Counsel and to give written notice of such selection to the other party, after which time such other party shall have five days to make a written objection to such alternate selection. If, within 30 days after submission of Indemnitee’s request for indemnification pursuant to Section 4.1, no Independent Counsel shall have been selected and not objected to, either the Company or Indemnitee may petition the Court for resolution of any objection that shall have been made by the Company or Indemnitee to the other’s selection of Independent Counsel and/or for the appointment as Independent Counsel of a person selected by the Court or by such other person as the Court shall designate, and the person with respect to whom an objection is so resolved or the person so appointed shall act as Independent Counsel under Section 4.2. The Company shall pay any and all fees of, and expenses reasonably incurred by, such Independent Counsel in connection with acting pursuant to Section 4.2, and the Company shall pay all fees and expenses reasonably incurred incident to the procedures of this Section 4.3, regardless of the manner in which such Independent Counsel was selected or appointed. Upon the due commencement of any judicial proceeding or arbitration pursuant to Section 5.1, Independent Counsel shall be discharged and relieved of any further responsibility in such capacity (subject to the applicable standards of professional conduct then prevailing).

Section 4.4    Establishment of a Trust. In the event of a Potential Change in Control or a Change in Control, the Company shall, upon written request by Indemnitee, create a trust for the benefit of Indemnitee (the “Trust”) and from time to time upon written request of Indemnitee shall fund the Trust in an amount sufficient to satisfy any and all Expenses reasonably anticipated at the time of each such request to be incurred in connection with investigating, preparing for, and defending any Claim, and any and all judgments, fines, penalties, and settlement amounts of any and all Claims from time to time actually paid or claimed, reasonably anticipated, or proposed to be paid. The amount to be deposited in the Trust pursuant to the foregoing funding obligation shall be determined by the Independent Counsel (or other person(s) making the determination of whether Indemnitee is permitted to be indemnified by applicable law). The terms of the Trust shall provide that, upon a Change in Control, (i) the Trust shall not be revoked or the principal thereof invaded, without the written consent of Indemnitee; (ii) the trustee of the Trust shall advance to Indemnitee, within ten days of a request by Indemnitee, any and all Expenses reasonably incurred by, or in case of retainer to be incurred by, or on behalf of Indemnitee (or, if applicable, reimburse Indemnitee for any Expense reasonably incurred by Indemnitee and previously paid by Indemnitee), with any required determination concerning the reasonableness of the Expenses to be made by the Independent Counsel (and Indemnitee hereby agrees to reimburse the Trust under the circumstances in which Indemnitee would be required to reimburse the Company for Expense Advances under Section 3.4 of this Agreement); (iii) the Trust shall continue to be funded by the Company in accordance with the funding obligation set forth above; (iv) the trustee of the Trust shall promptly pay to Indemnitee all amounts for which Indemnitee shall be entitled to Expense Advances and indemnification pursuant to this Agreement; and (v) all unexpended funds in the Trust shall revert to the Company upon a final determination by the Independent Counsel or the Court, as the case may be, that Indemnitee has been fully indemnified under the terms of this Agreement. The trustee of the Trust shall be chosen by Indemnitee and shall be an institution that is not affiliated with Indemnitee. Nothing in this Section 4.4 shall relieve the Company of any of its obligations under this Agreement.



Section 4.5    Presumptions and Effect of Certain Proceedings.

(a)    Indemnitee shall be presumed to be entitled to indemnification under this Agreement upon submission of a request for indemnification under Section 4.1, and the Company shall have the burden of proof in overcoming that presumption in reaching a determination contrary to that presumption. Such presumption shall be used by Independent Counsel (or other person or persons determining entitlement to indemnification) as a basis for a determination of entitlement to indemnification unless the Company provides information sufficient to overcome such presumption by clear and convincing evidence or unless the investigation, review and analysis of Independent Counsel (or such other person or persons) convinces Independent Counsel by clear and convincing evidence that the presumption should not apply.

(b)    If the person or persons empowered or selected under Article IV of this Agreement to determine whether Indemnitee is entitled to indemnification shall not have made a determination within 60 days after receipt by the Company of the request by Indemnitee therefor, the determination of entitlement to indemnification shall be deemed to have been made and Indemnitee shall be entitled to such indemnification; provided, however, that such 60-day period may be extended for a reasonable time, not to exceed an additional 30 days, if the person making the determination with respect to entitlement to indemnification in good faith requires such additional time for the obtaining or evaluating of documentation and/or information relating to such determination; and provided, further, that the 60-day limitation set forth in this Section 4.5(b) shall not apply and such period shall be extended as necessary (i) if within 30 days after receipt by the Company of the request for indemnification under Section 4.1 Indemnitee and the Company have agreed, and the Board has resolved, to submit such determination to the stockholders of the Company pursuant to Section 4.2(b) for their consideration at an annual meeting of stockholders to be held within 90 days after such agreement and such determination is made thereat, or at a special meeting of stockholders that is called within 30 days after such receipt for the purpose of making such determination, such meeting is held for such purpose within 60 days after having been so called and such determination is made thereat, or (ii) if the determination of entitlement to indemnification is to be made by Independent Counsel pursuant to Section 4.2(a) of this Agreement, in which case the applicable period shall be as set forth in Section 5.1(c).

(c)    The termination of any Proceeding or of any Claim, issue or matter by judgment, order, settlement (whether with or without court approval) or conviction, or upon a plea of nolo contendere or its equivalent, shall not (except as otherwise expressly provided in this Agreement) by itself adversely affect the rights of Indemnitee to indemnification or create a presumption that Indemnitee failed to meet any particular standard of conduct, that Indemnitee had any particular belief, or that a court has determined that indemnification is not permitted by applicable law. Indemnitee shall be deemed to have been found



liable in respect of any Claim, issue or matter only after Indemnitee shall have been so adjudged by the Court after exhaustion of all appeals therefrom.

(d)    For purposes of Section 3.6, a settlement or other resolution of a Proceeding short of final judgment may be successful if it permits a party to avoid expense, delay, distraction, disruption and uncertainty. For purposes of Section 3.6, in the event that any Proceeding to which Indemnitee is a party is resolved in any manner other than by adverse judgment against Indemnitee (including settlement of such Proceeding with or without payment of money or other consideration), it shall be presumed that Indemnitee has been successful on the merits or otherwise in such Proceeding. Anyone seeking to overcome this presumption shall have the burden of proof by clear and convincing evidence.

(e)    The failure of the Company (including by its directors or Independent Counsel) to have made a determination before the commencement of any action pursuant to this Agreement that indemnification is proper because Indemnitee has met the applicable standard of conduct shall not be a defense to the action or create a presumption that Indemnitee has not met the standard of conduct.

ARTICLE V

Certain Remedies of Indemnitee

Section 5.1    Indemnitee Entitled to Adjudication in an Appropriate Court. If (a) a determination is made pursuant to Article IV that Indemnitee is not entitled to indemnification under this Agreement; (b) there has been any failure by the Company to make timely payment or advancement of any amounts due hereunder (including any Expense Advances); or (c) the determination of entitlement to indemnification is to be made by Independent Counsel pursuant to Section 4.2 and such determination shall not have been made and delivered in a written opinion within 90 days after the latest of (i) such Independent Counsel’s being appointed, (ii) the overruling by the Court of objections to such counsel’s selection, or (iii) expiration of all periods for the Company or Indemnitee to object to such counsel’s selection, Indemnitee shall be entitled to commence an action seeking an adjudication in the Court of Indemnitee’s entitlement to such indemnification or advancements due hereunder, including Expense Advances. Alternatively, Indemnitee, at Indemnitee’s option, may seek an award in arbitration to be conducted by a single arbitrator pursuant to the commercial arbitration rules of the American Arbitration Association. Indemnitee shall commence such action seeking an adjudication or an award in arbitration within 180 days following the date on which Indemnitee first has the right to commence such action pursuant to this Section 5.1, or such right shall expire. The Company agrees not to oppose Indemnitee’s right to seek any such adjudication or award in arbitration and it shall continue to pay Expense Advances pursuant to Section 3.4 until it shall ultimately be determined (in a final adjudication by a court from which there is no further right of appeal or in a final adjudication of an arbitration pursuant to this Section 5.1 if Indemnitee elects to seek such arbitration) that Indemnitee is not entitled to be indemnified by the Company against such Expenses.




Section 5.2    Adverse Determination Not to Affect any Judicial Proceeding. If a determination shall have been made pursuant to Article IV that Indemnitee is not entitled to indemnification under this Agreement, any judicial proceeding or arbitration commenced pursuant to this Article V shall be conducted in all respects as a de novo trial or arbitration on the merits, and Indemnitee shall not be prejudiced by reason of such initial adverse determination. In any judicial proceeding or arbitration commenced pursuant to this Article V, Indemnitee shall be presumed to be entitled to indemnification or advancement of Expenses, as the case may be, under this Agreement and the Company shall have the burden of proof in overcoming such presumption and to show by clear and convincing evidence that Indemnitee is not entitled to indemnification or advancement of Expenses, as the case may be.

Section 5.3    Company Bound by Determination Favorable to Indemnitee in any Judicial Proceeding or Arbitration. If a determination shall have been made or deemed to have been made pursuant to Article IV that Indemnitee is entitled to indemnification, the Company shall be irrevocably bound by such determination in any judicial proceeding or arbitration commenced pursuant to this Article V, and shall be precluded from asserting that such determination has not been made or that the procedure by which such determination was made is not valid, binding and enforceable.

Section 5.4    Company Bound by the Agreement. The Company shall be precluded from asserting in any judicial proceeding or arbitration commenced pursuant to this Article V that the procedures and presumptions of this Agreement are not valid, binding and enforceable and shall stipulate in any such court or before any such arbitrator that the Company is bound by all the provisions of this Agreement. Without limiting the generality of the preceding sentence, the Company shall not seek from a court, or agree to, a “bar order” that would have the effect of prohibiting or limiting Indemnitee’s rights to advancement of any Expenses under this Agreement.

ARTICLE VI

Contribution

Section 6.1    Contribution Payment.

(a)    To the fullest extent permitted by law, whether or not the indemnification provided in Article III hereof is available, in respect of any threatened, pending or completed action, suit or Proceeding in which the Company is jointly liable with Indemnitee (or would be if joined in such action, or Proceeding), the Company shall pay, in the first instance, the entire amount of any judgment or settlement of such action, suit or Proceeding without requiring Indemnitee to contribute to such payment, and the Company hereby waives and relinquishes any right of contribution it may have against Indemnitee. The Company shall not enter into any settlement of any action, suit or Proceeding in which the Company is jointly liable with Indemnitee (or would be if joined in such action, suit or Proceeding) unless such settlement provides for a full and final release of all claims asserted against Indemnitee.




(b)    Without diminishing or impairing the obligations of the Company set forth in the preceding subparagraph, if, for any reason, Indemnitee shall elect or be required to pay all or any portion of any judgment or settlement in any threatened, pending or completed action, suit or Proceeding in which the Company is jointly liable with Indemnitee (or would be if joined in such action, suit or Proceeding), the Company shall contribute to the amount of Expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred and paid or payable by Indemnitee in proportion to the relative benefits received by the Company and all officers, directors or employees of the Company, other than Indemnitee, who are jointly liable with Indemnitee (or would be if joined in such action, suit or Proceeding), on the one hand, and Indemnitee, on the other hand, from the transaction or events from which such action, suit or Proceeding arose; provided, however, that the proportion determined on the basis of relative benefit may, to the extent necessary to conform to law, be further adjusted by reference to the relative fault of the Company and all officers, directors or employees of the Company other than Indemnitee who are jointly liable with Indemnitee (or would be if joined in such action, suit or Proceeding), on the one hand, and Indemnitee, on the other hand, in connection with the transaction or events that resulted in such Expenses, judgments, fines or settlement amounts, as well as any other equitable considerations that applicable law may require to be considered.

(c)    The Company hereby agrees, to the fullest extent permitted by applicable law, to fully indemnify and hold Indemnitee harmless from any claims of contribution that may be brought by officers, directors or employees of the Company, other than Indemnitee, who may be jointly liable with Indemnitee.

(d)    To the fullest extent permissible under applicable law and without diminishing or impairing the obligations of the Company set forth in the preceding subparagraphs of this Section 6.1, if the indemnification provided for in this Agreement is unavailable to Indemnitee for any reason whatsoever, the Company, in lieu of indemnifying Indemnitee, shall contribute to the amount incurred by Indemnitee, whether for judgments, fines, penalties, excise taxes, amounts paid or to be paid in settlement and/or for Expenses, in connection with any claim relating to an indemnifiable event under this Agreement, in such proportion as is deemed fair and reasonable in light of all of the circumstances of such Proceeding in order to reflect (i) the relative benefits received by the Company and Indemnitee as a result of the event(s) and/or transaction(s) giving cause to such Proceeding; and/or (ii) the relative fault of the Company (and its directors, officers, employees and agents) and Indemnitee in connection with such event(s) and/or transaction(s).

Section 6.2    Relative Fault. The relative fault of Indemnitee, on the one hand, and of the Company and any and all other parties (including officers and directors of the Company other than Indemnitee) who may be at fault with respect to such matter shall be determined (i) by reference to the relative fault of Indemnitee as determined by the court or other governmental agency assessing the contribution amounts or (ii) to the extent such



court or other governmental agency does not apportion relative fault, by the Independent Counsel (or such other party that makes a determination under Article IV) after giving effect to, among other things, the degree to which their actions were motivated by intent to gain personal profit or advantage, the degree to which their liability is primary or secondary, the degree to which their conduct is active or passive, the degree of the knowledge, access to information, and opportunity to prevent or correct the subject matter of the Proceedings and other relevant equitable considerations of each party. The Company and Indemnitee agree that it would not be just and equitable if contribution pursuant to this Section 6.2 were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in this Section 6.2.

ARTICLE VII

Miscellaneous

Section 7.1    Non-Exclusivity. The rights of Indemnitee to receive indemnification and Expense Advances under this Agreement shall be in addition to, and shall not be deemed exclusive of, any other rights that Indemnitee may be entitled to under the DGCL or other applicable law, the Certificate of Incorporation or Bylaws, any other agreement, vote of stockholders or a resolution of directors, or otherwise. Every other right or remedy of Indemnitee shall be cumulative of the rights and remedies granted Indemnitee hereunder. No amendment or alteration of the Certificate of Incorporation or Bylaws or any provision thereof shall adversely affect Indemnitee’s rights hereunder, and such rights shall be in addition to any rights Indemnitee may have under the Certificate of Incorporation, Bylaws and the DGCL or other applicable law. To the extent that there is a change in the DGCL or other applicable law (whether by statute or judicial decision) that allows greater indemnification by agreement than would be afforded currently under the Certificate of Incorporation or Bylaws and this Agreement, it is the intent of the parties hereto that Indemnitee shall enjoy by virtue of this Agreement the greater benefit so afforded by such change. Any amendment, alteration or repeal of the DGCL that adversely affects any right of Indemnitee shall be prospective only and shall not limit or eliminate any such right with respect to any Proceeding involving any occurrence or alleged occurrence of any action or omission to act that took place before the effective date of such amendment or repeal. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other right or remedy.

Section 7.2    Insurance and Subrogation.

(a)    To the extent that the Company maintains an insurance policy or policies providing liability insurance for directors, officers, employees, agents or fiduciaries of the Company or for individuals serving at the request of the Company as directors, officers, partners, members, venturers, proprietors, trustees, employees, agents, fiduciaries or similar functionaries of another foreign or domestic corporation, partnership, limited liability company, joint venture, sole proprietorship, trust, employee benefit plan or other enterprise, Indemnitee shall



be covered by such policy or policies in accordance with its or their terms to the maximum extent of the coverage available for any such director, officer, employee, agent or fiduciary under such policy or policies; provided, however, that the Company shall not be in breach of this Section 7.2(a) by reason of obtaining any independent director liability insurance policies. If, at the time of the receipt of notice of a claim pursuant to the terms hereof, the Company has director and officer liability insurance in effect, the Company shall give prompt notice of such claim or of the commencement of a Proceeding, as the case may be, to the insurers in accordance with the procedures set forth in the respective policies. The Company shall thereafter take all necessary or desirable action to cause such insurers to pay, on behalf of the Indemnitee, all amounts payable as a result of such Proceeding in accordance with the terms of such policies.

(b)    In the event of any payment by the Company under this Agreement, the Company shall be subrogated to the extent of such payment to all of the rights of recovery of Indemnitee, who shall execute all papers required and take all action necessary to secure such rights, including execution of such documents as are necessary to enable the Company to bring suit to enforce such rights, provided that all Expenses relating to such action shall be borne by the Company.

(c)    The Company shall not be liable under this Agreement to make any payment of amounts otherwise indemnifiable hereunder if and to the extent that Indemnitee has otherwise actually received such payment under the Certificate of Incorporation or Bylaws or any insurance policy, contract, agreement or otherwise.

(d)    If Indemnitee is a director of the Company, the Company will advise the Board of any proposed material reduction in the amount of coverage limits for Indemnitee to be provided by the Company’s directors’ and officers’ liability insurance policy and will not effect such a reduction with respect to Indemnitee without the prior approval of at least 80% of the Independent Directors of the Company.

(e)    If Indemnitee is a director of the Company during the term of this Agreement and if Indemnitee ceases to be a director of the Company for any reason, the Company shall procure a run-off directors’ and officers’ liability insurance policy with respect to claims arising from facts or events that occurred before the time Indemnitee ceased to be a director of the Company and covering Indemnitee, which policy, without any lapse in coverage, will provide coverage for a period of six years after the time Indemnitee ceased to be a director of the Company and will provide coverage (including amount and type of coverage and size of deductibles) that are substantially comparable to the Company’s directors’ and officers’ liability insurance policy that was most protective of Indemnitee in the 12 months preceding the time Indemnitee ceased to be a director of the Company; provided, however, that:



(i)    this obligation shall be suspended during the period immediately following the time Indemnitee ceases to be a director of the Company if and only so long as the Company has a directors’ and officers’ liability insurance policy in effect covering Indemnitee for such claims that, if it were a run-off policy, would meet or exceed the foregoing standards, but in any event this suspension period shall end when a Change in Control occurs; and

(ii)    no later than the end of the suspension period provided in the preceding clause (i) (whether because of failure to have a policy meeting the foregoing standards or because a Change in Control occurs), the Company shall procure a run-off directors’ and officers’ liability insurance policy meeting the foregoing standards and lasting for the remainder of the six-year period.

(f)    Notwithstanding the preceding clause (e) including the suspension provisions therein, if Indemnitee ceases to be an officer or a director of the Company in connection with a Change in Control or at or during the one-year period following the occurrence of a Change in Control, the Company shall procure a run-off directors’ and officers’ liability insurance policy covering Indemnitee and meeting the foregoing standards in clause (e) and lasting for a six-year period upon Indemnitee’s ceasing to be an officer or a director of the Company in such circumstances.

(g)    If at the time of the receipt of a notice of a Claim or Proceeding pursuant to the terms hereof, the Company has directors’ and officers’ liability insurance in effect, the Company shall give prompt notice of the commencement of such Claim or Proceeding to the insurers in accordance with the procedures set forth in the respective policies. The Company shall thereafter take all necessary or desirable action to cause such insurers to pay, on behalf of Indemnitee, all amounts payable as a result of such Claim or Proceeding in accordance with the terms of such policies.

Section 7.3    Self Insurance of the Company; Other Arrangements. The parties hereto recognize that the Company may, but except as provided in Section 7.2(d), Section 7.2(e), and Section 7.2(f) is not required to, procure or maintain insurance or other similar arrangements, at its expense, to protect itself and any person, including Indemnitee, who is or was a director, officer, employee, agent or fiduciary of the Company or who is or was serving at the request of the Company as a director, officer, partner, member, venturer, proprietor, trustee, employee, agent, fiduciary or similar functionary of another foreign or domestic corporation, partnership, limited liability company, joint venture, sole proprietorship, trust, employee benefit plan or other enterprise against any expense, liability or loss asserted against or incurred by such person, in such a capacity or arising out of the person’s status as such a person, whether or not the Company would have the power to indemnify such person against such expense or liability or loss.




Except as provided in Section 7.2(d), Section 7.2(e) and Section 7.2(f), in considering the cost and availability of such insurance, the Company (through the exercise of the business judgment of its directors and officers) may, from time to time, purchase insurance that provides for certain (i) deductibles or retentions, (ii) limits on payments required to be made by the insurer, or (iii) coverage that may not be as comprehensive as that previously included in insurance purchased by the Company or its predecessors. The purchase of insurance with deductibles or retentions, limits on payments and coverage exclusions, even if in the best interest of the Company, may not be in the best interest of Indemnitee. As to the Company, purchasing insurance with deductibles or retentions, limits on payments and coverage exclusions is similar to the Company’s practice of self-insurance in other areas. In order to protect Indemnitee who would otherwise be more fully or entirely covered under such policies, the Company shall, to the maximum extent permitted by applicable law, indemnify and hold Indemnitee harmless to the extent (i) of such deductibles or retentions and (ii) of amounts exceeding payments made by an insurer, if by reason of Indemnitee’s Corporate Status Indemnitee is or is threatened to be made a party to any Proceeding. The obligation of the Company in the preceding sentence shall be without regard to whether the Company would otherwise be required to indemnify such officer or director under the other provisions of this Agreement, or under any law, agreement, vote of stockholders or directors or other arrangement. Without limiting the generality of any provision of this Agreement, the procedures in Article IV hereof shall, to the extent applicable, be used for determining entitlement to indemnification under this Section 7.3.

Section 7.4    Certain Settlement Provisions. The Company shall have no obligation to indemnify Indemnitee under this Agreement for amounts paid in settlement of a Proceeding or Claim without the Company’s prior written consent. The Company shall not settle any Proceeding or Claim in any manner that would impose any fine or other obligation on Indemnitee without Indemnitee’s prior written consent. Neither the Company nor Indemnitee shall unreasonably withhold their consent to any proposed settlement.

Section 7.5    Duration of Agreement. This Agreement shall continue for so long as Indemnitee serves as a director, officer, employee, agent or fiduciary of the Company or, at the request of the Company, as a director, officer, partner, member, venturer, proprietor, trustee, employee, agent, fiduciary or similar functionary of another foreign or domestic corporation, partnership, limited liability company, joint venture, sole proprietorship, trust, employee benefit plan or other enterprise, and shall continue thereafter so long as Indemnitee shall be subject to any possible Proceeding (including any rights of appeal thereto and any Proceeding commenced by Indemnitee pursuant to Article V of this Agreement) by reason of Indemnitee’s Corporate Status, whether or not Indemnitee is acting in any such capacity at the time any liability or expense is incurred for which indemnification or advancement can be provided under this Agreement.

Section 7.6    Notice by Each Party. Indemnitee shall promptly notify the Company in writing upon being served with any summons, citation, subpoena, complaint, indictment, information or other document or communication relating to any Proceeding or Claim for which Indemnitee may be entitled to indemnification or advancement of



Expenses hereunder; provided, however, that any failure of Indemnitee to so notify the Company shall not adversely affect Indemnitee’s rights under this Agreement except to the extent the Company shall have been materially prejudiced as a direct result of such failure. The Company shall promptly notify Indemnitee in writing as to the pendency of any Proceeding or Claim that may involve a claim against Indemnitee for which Indemnitee may be entitled to indemnification or advancement of Expenses hereunder.

Section 7.7    Amendment. This Agreement may not be modified or amended except by a written instrument executed by or on behalf of each of the parties hereto.

Section 7.8    Waivers. The observance of any term of this Agreement may be waived (either generally or in a particular instance and either retroactively or prospectively) by the party entitled to enforce such term only by a writing signed by the party against which such waiver is to be asserted. Unless otherwise expressly provided herein, no delay on the part of any party hereto in exercising any right, power or privilege hereunder shall operate as a waiver thereof, nor shall any waiver on the part of any party hereto of any right, power or privilege hereunder operate as a waiver of any other right, power or privilege hereunder nor shall any single or partial exercise of any right, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, power or privilege hereunder.

Section 7.9    Entire Agreement. This Agreement and the documents expressly referred to herein constitute the entire agreement between the parties hereto with respect to the matters covered hereby, and any other prior or contemporaneous oral or written understandings or agreements with respect to the matters covered hereby, including any prior indemnification agreements, are expressly superseded and replaced by this Agreement.

Section 7.10    Severability. If any provision of this Agreement (including any provision within a single section, paragraph or sentence) or the application of such provision to any Person or circumstance, shall be judicially declared to be invalid, unenforceable or void, such decision will not have the effect of invalidating or voiding the remainder of this Agreement or affect the application of such provision to other Persons or circumstances, it being the intent and agreement of the parties that this Agreement shall be deemed amended by modifying such provision to the extent necessary to render it valid, legal and enforceable while preserving its intent, or if such modification is not possible, by substituting therefor another provision that is valid, legal and enforceable and that achieves the same objective. Any such finding of invalidity or unenforceability shall not prevent the enforcement of such provision in any other jurisdiction to the maximum extent permitted by applicable law.

Section 7.11    Notices. All notices and other communications hereunder shall be in writing and shall be deemed given upon (a) transmitter’s confirmation of a receipt of a facsimile transmission if during normal business hours of the recipient, otherwise on the next business day, (b) confirmed delivery of a standard overnight courier or when delivered by hand or (c) the expiration of five business days after the date mailed by certified or registered mail (return receipt requested), postage prepaid, to the parties at the



following addresses (or at such other addresses for a party as shall be specified by like notice):

or to such other address or to such other individuals as any party shall have last designated by notice to the other parties. All notices and other communications given to any party in accordance with the provisions of this Agreement shall be deemed to have been given when delivered or sent to the intended recipient thereof in accordance with and as provided in the provisions of this Section 7.11.

Section 7.12    Governing Law. This Agreement shall be construed in accordance with and governed by the laws of the State of Delaware without regard to the principles of conflict of laws.

Section 7.13    Certain Construction Rules.

(a)    The article and section headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. As used in this Agreement, unless otherwise provided to the contrary, (1) all references to days shall be deemed references to calendar days and (2) any reference to a “Section” or “Article” shall be deemed to refer to a section or article of this Agreement. The words “hereof,” “herein” and “hereunder” and words of similar import referring to this Agreement refer to this Agreement as a whole and not to any particular provision of this Agreement. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” Unless otherwise specifically provided for herein, the term “or” shall not be deemed to be exclusive. Whenever the context may require, any pronoun used in this Agreement shall include the corresponding masculine, feminine or neuter forms, and the singular form of nouns, pronouns and verbs shall include the plural and vice versa.

(b)    For purposes of this Agreement, references to “other enterprises” shall include employee benefit plans; references to “fines” shall include any excise taxes assessed on a person with respect to any employee benefit plan;



references to “serving at the request of the Company” shall include any service as a director, officer, employee or agent of the Company that imposes duties on, or involves services by, such director, nominee, officer, employee or agent with respect to an employee benefit plan, its participants or beneficiaries; and a person who acted in good faith and in a manner the person reasonably believed to be in the interests of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in a manner “not opposed to the best interest of the Company” for purposes of this Agreement and the DGCL.

(c)    In the event of a merger, consolidation or amalgamation of the Company with or into any other entity, references to the “Company” shall include the entity surviving or resulting from the merger, consolidation or amalgamation as well as the Company, and Indemnitee shall stand in the same position under this Agreement with respect to the surviving or resulting entity as Indemnitee would stand with respect to the Company if its existence had continued upon and after the merger, consolidation or amalgamation.

Section 7.14    Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed to be an original and all of which together shall be deemed to be one and the same instrument, notwithstanding that both parties are not signatories to the original or same counterpart.

Section 7.15    Certain Persons Not Entitled to Indemnification. In addition, the Company shall not be obligated pursuant to the terms of this Agreement:

(a)    To indemnify Indemnitee if (and to the extent that) a final decision by a court or arbitration body having jurisdiction in the matter shall determine that such indemnification is not lawful; or

(b)    To indemnify Indemnitee for the payment to the Company of profits pursuant to Section 16(b) of the Exchange Act, or Expenses incurred by Indemnitee for Proceedings in connection with such payment under Section 16(b) of the Exchange Act.

Section 7.16    Indemnification for Negligence, Gross Negligence, etc. Without limiting the generality of any other provision hereunder, it is the express intent of this Agreement that Indemnitee be indemnified and Expenses be advanced regardless of Indemnitee’s acts of negligence, gross negligence, intentional or willful misconduct to the extent that indemnification and advancement of Expenses is allowed pursuant to the terms of this Agreement and under applicable law.

Section 7.17    Mutual Acknowledgments. Both the Company and Indemnitee acknowledge that in certain instances, applicable law (including applicable federal law that may preempt or override applicable state law) or public policy may prohibit the Company from indemnifying the directors, officers, employees, agents or fiduciaries of the Company under this Agreement or otherwise. For example, the Company and Indemnitee acknowledge that the U.S. Securities and Exchange Commission has taken



the position that indemnification of directors, officers and controlling Persons of the Company for liabilities arising under federal securities laws is against public policy and, therefore, unenforceable. Indemnitee understands and acknowledges that the Company has undertaken or may be required in the future to undertake with the U.S. Securities and Exchange Commission to submit the question of indemnification to a court in certain circumstances for a determination of the Company’s right under public policy to indemnify Indemnitee. In addition, the Company and Indemnitee acknowledge that federal law prohibits indemnifications for certain violations of the Employee Retirement Income Security Act of 1974, as amended.

Section 7.18    Enforcement. The Company agrees that its execution of this Agreement shall constitute a stipulation by which it shall be irrevocably bound in any court or arbitration in which a proceeding by Indemnitee for enforcement of Indemnitee’s rights hereunder shall have been commenced, continued or appealed, that its obligations set forth in this Agreement are unique and special, and that failure of the Company to comply with the provisions of this Agreement will cause irreparable and irremediable injury to Indemnitee, for which a remedy at law will be inadequate. As a result, in addition to any other right or remedy Indemnitee may have at law or in equity with respect to breach of this Agreement, Indemnitee shall be entitled to injunctive or mandatory relief directing specific performance by the Company of its obligations under this Agreement. The Company agrees not to seek, and agrees to waive any requirement for the securing or posting of, a bond in connection with Indemnitee’s seeking or obtaining such relief.

Section 7.19    Successors and Assigns. All of the terms and provisions of this Agreement shall be binding upon, shall inure to the benefit of and shall be enforceable by the parties hereto and their respective successors, assigns, heirs, executors, administrators, and legal representatives.

Section 7.20    Period of Limitations. No legal action shall be brought and no cause of action shall be asserted by or on behalf of the Company or any affiliate of the Company against Indemnitee or Indemnitee’s spouse, heirs, executors, or personal or legal representatives after the expiration of one year from the date of accrual of that cause of action, and any claim or cause of action of the Company or its affiliate shall be extinguished and deemed released unless asserted by the timely filing of a legal action within that one-year period; provided, however, that for any claim based on Indemnitee’s breach of fiduciary duties to the Company or its stockholders, the period set forth in the preceding sentence shall be three years instead of one year; and provided, further, that, if any shorter period of limitations is otherwise applicable to any such cause of action, the shorter period shall govern.

Mr. Ken Rockwood
Pioneer Natural Resources Company
777 Hidden Ridge
Irving, Texas 75038

Dear Mr. Rockwood:

In accordance with your request, we have audited the estimates prepared by Pioneer Natural Resources Company (Pioneer), as of December 31, 2020, of the proved reserves and future revenue to the Pioneer interest in certain oil and gas properties located in the Permian Basin, Texas. It is our understanding that the proved reserves estimates shown herein constitute all of the proved reserves owned by Pioneer. We have examined the estimates with respect to reserves quantities, reserves categorization, future producing rates, future net revenue, and the present value of such future net revenue, using the definitions set forth in U.S. Securities and Exchange Commission (SEC) Regulation S-X Rule 4-10(a). The estimates of reserves and future revenue have been prepared in accordance with the definitions and regulations of the SEC and, with the exception of the exclusion of future income taxes, conform to the FASB Accounting Standards Codification Topic 932, Extractive Activities—Oil and Gas. We completed our audit on or about the date of this letter. This report has been prepared for Pioneer's use in filing with the SEC; in our opinion the assumptions, data, methods, and procedures used in the preparation of this report are appropriate for such purpose.

The following table sets forth Pioneer's estimates of the net reserves and future net revenue, as of December 31, 2020, for the audited properties:

Net Reserves Future Net Revenue (M$)
Oil NGL Gas Present Worth
Category (MBBL) (MBBL) (MMCF) Total at 10%
Proved Developed Producing 538,093 361,821 1,851,983 13,750,934 7,445,169
Proved Developed Non-Producing 1,227 763 3,624 44,722 26,207
Proved Undeveloped 29,464 16,603 84,493 653,517 224,660
   Total Proved
568,784 379,187 1,940,100 14,449,174 7,696,036
Totals may not add because of rounding.
The oil volumes shown include crude oil and condensate. Oil and natural gas liquids (NGL) volumes are expressed in thousands of barrels (MBBL); a barrel is equivalent to 42 United States gallons. Gas volumes are expressed in millions of cubic feet (MMCF) at standard temperature and pressure bases.

When compared on a lease-by-lease basis, some of the estimates of Pioneer are greater and some are less than the estimates of Netherland, Sewell & Associates, Inc. (NSAI). However, in our opinion the estimates shown herein of Pioneer's reserves and future revenue are reasonable when aggregated at the proved level and have been prepared in accordance with the Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information promulgated by the Society of Petroleum Engineers (SPE Standards). Additionally, these estimates are within the recommended 10 percent tolerance threshold set forth in the SPE Standards. We are satisfied with the methods and procedures used by Pioneer in preparing the December 31, 2020, estimates of reserves and future revenue, and we saw nothing of an unusual nature that would cause us to take exception with the estimates, in the aggregate, as prepared by Pioneer.

Reserves categorization conveys the relative degree of certainty; reserves subcategorization is based on development and production status. The estimates of reserves and future revenue included herein have not been adjusted for risk. Pioneer's estimates do not include probable or possible reserves that may exist for these properties, nor do they include any value for undeveloped acreage beyond those tracts for which undeveloped reserves have been estimated.

Prices used by Pioneer are based on the 12-month unweighted arithmetic average of the first-day-of-the-month price for each month in the period January through December 2020. For oil and NGL volumes, the average West Texas Intermediate spot price of $39.57 per barrel is adjusted by property group for quality, transportation fees, and market differentials. For gas volumes, the average Henry Hub spot price of $1.98 per MMBTU is adjusted by property group for energy content, transportation fees, and market differentials. All prices are held constant throughout the lives of the properties. The average adjusted product prices weighted by production over the remaining lives of the properties are $37.40 per barrel of oil, $15.24 per barrel of NGL, and $1.81 per MCF of gas.

Operating costs used by Pioneer are based on historical operating expense records. For the nonoperated properties, these costs include the per-well overhead expenses allowed under joint operating agreements along with estimates of costs to be incurred at and below the district and field levels. Operating costs for the operated properties are limited to direct lease- and field-level costs and Pioneer's estimate of the portion of its headquarters general and administrative overhead (G&A) expenses necessary to operate the properties. Pioneer's estimates of G&A expenses are included at the division level. Operating costs have been divided into division-level costs, per-well costs, and per-unit-of-production costs. Capital costs used by Pioneer are based on authorizations for expenditure and actual costs from recent activity. Capital costs are included as required for workovers, new development wells, and production equipment. Abandonment costs used are Pioneer's estimates of the costs to abandon the wells and production facilities, net of any salvage value. Operating, capital, and abandonment costs are not escalated for inflation.

The reserves shown in this report are estimates only and should not be construed as exact quantities. Proved reserves are those quantities of oil and gas which, by analysis of engineering and geoscience data, can be estimated with reasonable certainty to be economically producible; probable and possible reserves are those additional reserves which are sequentially less certain to be recovered than proved reserves. Estimates of reserves may increase or decrease as a result of market conditions, future operations, changes in regulations, or actual reservoir performance. In addition to the primary economic assumptions discussed herein, estimates of Pioneer and NSAI are based on certain assumptions including, but not limited to, that the properties will be developed consistent with current development plans as provided to us by Pioneer, that the properties will be operated in a prudent manner, that no governmental regulations or controls will be put in place that would impact the ability of the interest owner to recover the reserves, and that projections of future production will prove consistent with actual performance. If the reserves are recovered, the revenues therefrom and the costs related thereto could be more or less than the estimated amounts. Because of governmental policies and uncertainties of supply and demand, the sales rates, prices received for the reserves, and costs incurred in recovering such reserves may vary from assumptions made while preparing these estimates.

It should be understood that our audit does not constitute a complete reserves study of the audited oil and gas properties. Our audit consisted primarily of substantive testing, wherein we conducted a detailed review of major properties making up approximately 89 percent of Pioneer's total proved reserves, which account for approximately 100 percent of the present worth of its reserves. In the conduct of our audit, we have not independently verified the accuracy and completeness of information and data furnished by Pioneer with respect to ownership interests, oil and gas production, well test data, historical costs of operation and development, product prices, or any agreements relating to current and future operations of the properties and sales of production. However, if in the course of our examination something came to our attention that brought into question the validity or sufficiency of any such information or data, we did not rely on such information or data until we had satisfactorily resolved our questions relating thereto or had independently verified such information or data. Our audit did not include a review of Pioneer's overall reserves management processes and practices.

We used standard engineering and geoscience methods, or a combination of methods, including performance analysis and analogy, that we considered to be appropriate and necessary to establish the conclusions set forth herein. As in all aspects of oil and gas evaluation, there are uncertainties inherent in the interpretation of engineering and geoscience data; therefore, our conclusions necessarily represent only informed professional judgment.

Supporting data documenting this audit, along with data provided by Pioneer, are on file in our office. The technical person primarily responsible for conducting this audit meets the requirements regarding qualifications, independence, objectivity, and confidentiality set forth in the SPE Standards. James E. Ball, a Licensed Professional Engineer in the State of Texas, has been practicing consulting petroleum engineering at NSAI since 1998 and has over 17 years of prior industry experience. We are independent petroleum engineers, geologists, geophysicists, and petrophysicists; we do not own an interest in these properties nor are we employed on a contingent basis.
