Parsley and DoublePoint Acquisitions
The Company completed the Parsley Acquisition on January 12, 2021. The Parsley
Acquisition was accounted for as a business combination, with the fair value of
the acquisition consideration allocated to the acquisition date fair value of
assets and liabilities acquired. Parsley's post-acquisition date results of
operations were included in the Company's interim consolidated financial
statements beginning on January 12, 2021. See   Note     3   of Notes to
Consolidated Financial Statements included in "Item 1. Financial Statements" for
additional information.
On May 4, 2021, the Company completed the acquisition of DoublePoint for total
consideration valued at approximately $6.2 billion, which was comprised of 27.2
million shares of Pioneer common stock, $1 billion of cash and the assumption of
approximately $890 million of debt. Although this Form 10-Q is being filed
following the completion of the DoublePoint Acquisition, unless otherwise
specifically noted, information set forth herein only relates to the period as
of and for the quarter ended March 31, 2021 and therefore does not include
information relating to DoublePoint 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 DoublePoint Acquisition and do not include DoublePoint or its subsidiaries.
The DoublePoint Acquisition will be accounted for as a business combination,
with the fair value of the acquisition consideration allocated to the
acquisition date fair value of assets and liabilities acquired. DoublePoint's
post-acquisition date results of operations will be included in the Company's
interim consolidated financial statements beginning in May 2021. See   Note 17
of Notes to Consolidated Financial Statements included in "Item 1. Financial
Statements" for additional information.
Financial and Operating Performance
The Company's financial and operating performance for the three months ended
March 31, 2021 included the following highlights:
•Net loss attributable to common stockholders for the three months ended
March 31, 2021 was $70 million ($0.33 per diluted share) as compared to net
income of $291 million ($1.75 per diluted share) for the same period in 2020.
The primary components of the $361 million decrease in earnings attributable to
common stockholders include:
•a $1.15 billion decrease in net derivative results, primarily due to changes in
forward commodity prices and the cash settlement of derivative positions in
accordance with their terms;
•a $219 million increase in other expense, primarily due to $197 million of
transaction costs related to the Parsley Acquisition and $80 million of costs
related to covering firm gas commitments during a winter weather event that
brought abnormally cold temperatures, along with snow and icy conditions across
the state of Texas in February 2021 known as Winter Storm Uri as compared to a
$69 million noncash charge for estimated deficiency payments related to the
Company's 2019 South Texas Divestiture during the three months ended March 31,
2020;
•a $114 million increase in production costs, including taxes, primarily
attributable to (i) an increase in production taxes as a result of a 33 percent
increase in average realized commodity prices per BOE and (ii) increased costs
attributable to production added from the Parsley Acquisition;
•a $40 million increase in DD&A expense, primarily due to an increase in sales
volumes from the Parsley Acquisition and the Company's successful horizontal
drilling program in the Permian Basin;
•a $12 million increase in general and administrative expense primarily due to
the reinstatement of certain employee benefits during 2021 that were suspended
during 2020 in response to the COVID-19 pandemic;
partially offset by:
•a $729 million increase in oil and gas revenues due to a 33 percent increase in
average realized commodity prices per BOE and a 26 percent increase in daily
sales volumes due to additional production from the Parsley Acquisition and the
Company's successful horizontal drilling program in the Permian Basin;
•a $266 million increase in net interest and other income (loss), primarily due
to (i) noncash gains attributable to the increase in the fair value of the
Company's investment in affiliate of $54 million during the three months ended
March 31, 2021 as compared to a noncash loss of $145 million for the same period
in 2020 and (ii) a $63 million noncash decrease in the fair value of the
divestiture contingent consideration associated with the South Texas Divestiture
for the three months ended March 31, 2020;
                                       31
--------------------------------------------------------------------------------

                       PIONEER NATURAL RESOURCES COMPANY
•a $98 million increase in net sales of purchased commodities primarily due to
an increase during the first quarter of 2021 in downstream oil margins on the
Company's Gulf Coast refinery and export sales; and
•an $88 million decrease in the Company's income tax provision due to the
decrease in earnings during the three months ended March 31, 2021 as compared to
the same period in 2020.
•During the three months ended March 31, 2021, average daily sales volumes
increased by 26 percent to 473,937 BOEPD, as compared to 375,163 BOEPD during
the same period in 2020, due to additional production from the Parsley
Acquisition and the Company's successful horizontal drilling program in the
Permian Basin, partially offset by a 45 MBOEPD loss in sales volumes due to
Winter Storm Uri in February 2021.
•Average oil and NGL prices per Bbl and average gas prices per Mcf increased to
$56.71, $25.90 and $3.04, respectively, during the three months ended March 31,
2021 as compared to $45.60, $14.52 and $1.61, respectively, for the same period
in 2020.
•Cash provided by operating activities decreased during the three months ended
March 31, 2021 to $377 million as compared to $825 million for the same period
in 2020. The decrease was primarily due to (i) additional cash used in
derivative activities, (ii) increased accounts receivables and commodity
inventories as a result of higher commodity prices, (iii) one-time cash Parsley
transaction costs and (iv) cash paid to fulfill certain gas commitments during
Winter Storm Uri, partially offset by an increase in accounts payable as a
result of increased drilling and operational activity and an increase in oil and
gas revenues due to the aforementioned increase in commodity prices.
•As of March 31, 2021 and December 31, 2020, the Company's net debt to book
capitalization was 23 percent and 14 percent, respectively.
Winter Storm Uri
During February 2021, the Company's operations in West Texas were significantly
impacted by Winter Storm Uri. 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 negatively impacted first quarter 2021
production by approximately 45 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 incurred incremental cash costs of $80 million
in connection with its firm gas sales commitments early in the weather event.
Impact of the COVID-19 Pandemic
The COVID-19 pandemic has resulted in a severe worldwide economic downturn,
significantly disrupting the demand for oil throughout the world, and has
created significant volatility, uncertainty and turmoil in the oil and gas
industry. The decrease in demand for oil combined with pressures on the global
supply-demand balance for oil and related products, resulted in oil prices
declining significantly beginning in late February 2020. The length of this
demand disruption is unknown, and there is significant uncertainty regarding the
long-term impact to global oil demand, which will ultimately depend on various
factors and consequences 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 economic downturn and the decrease in oil demand,
the speed and effectiveness of responses to combat the virus, and the time
necessary to balance oil supply and demand to restore oil pricing.
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.
Second Quarter 2021 Outlook
The Company's operating and financial results for the second quarter of 2021 and
beyond are uncertain and 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; 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; uncertainty in oil

______________________
(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. It also includes the
expected cash flow impact from the Company's firm transportation marketing
contracts that are accounted for as derivatives.
2021 Revised Capital Budget
With the completion of the DoublePoint Acquisition, the Company's capital budget
for 2021 has been revised and is expected to be in the range of $3.1 billion to
$3.4 billion, consisting of $2.9 billion to $3.1 billion for drilling and
completion related activities, including additional tank batteries and saltwater
disposal facilities, $150 million of estimated Parsley and DoublePoint
integration costs and $90 million for water infrastructure and vehicles. The
Company's capital expenditures for the three months ended March 31, 2021 were
$605 million. The 2021 capital budget and actual capital expenditures for the
three months ended March 31, 2021 excludes acquisitions, asset retirement
obligations, capitalized interest, 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.

The increase in average daily BOE sales volumes for the three months ended
March 31, 2021, as compared to the same period in 2020 was due to the Company's
successful Spraberry/Wolfcamp horizontal drilling program and the Parsley
Acquisition, partially offset by the 45 MBOEPD production loss due to Winter
Storm Uri in February 2021.

Purchased commodities. The Company enters into pipeline capacity commitments in
order to secure available oil, NGLs and gas transportation capacity from the
Company's areas of production and secure diesel supply from the Gulf Coast to
the Company's operations in the Permian Basin. 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 in sales of purchased commodities and purchased commodities in the
accompanying consolidated statements of operations 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. The Company has also entered
into long-term marketing contracts, which are accounted for as derivatives, to
similarly diversify its oil sales to Gulf Coast and international markets. The
gains and losses associated with the Company's marketing derivatives are
recognized in net derivative gains (losses) in the consolidated statements of
operations. 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 sales of
purchased commodities are included in purchased commodities expense. See

The increase in net sales of purchased commodities for the three months ended
March 31, 2021, as compared to the same periods in 2020, was primarily due to an
increase in first quarter of 2021 downstream oil margins on the Company's Gulf
Coast refinery and export sales.
Firm transportation payments on excess pipeline capacity are included in other
expense in the accompanying consolidated statements of operations. See   Note

The increase in net interest and other income (loss) for the three months ended
March 31, 2021, as compared to the same period in 2020, was primarily due to a
noncash gain of $54 million attributable to the increase in fair value of the
Company's investment in affiliate during the three months ended March 31, 2021
compared to a noncash loss of $145 million attributable to the decrease in fair
value of the Company's investment in affiliate and a $63 million noncash loss
attributable to the decrease in the fair value of divestiture contingent
consideration associated with the South Texas Divestiture for the three months
ended March 31, 2020.

_____________________
(a)Lease operating expense and workover expense 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, transport and fractionate the Company's gas and NGLs to a 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.
Although the Company continues to realize the benefit of lower production costs
in 2021 due to the Company's cost saving initiatives, the Company realized
higher than expected production costs during the three months ended March 31,
2021 compared to the same period in 2020 due to the following:
•Lease operating expense per BOE increased due to an increase in electricity
costs, increased maintenance and repair costs and lower production associated
with the impact Winter Storm Uri had on the Company's operations in February
2021;
•Gathering, processing and transportation expense per BOE increased primarily
due to (i) transportation costs related to new pipeline takeaway capacity for
the Company's gas and NGL production, (ii) increased gas processing and
transportation costs as a result of higher electricity costs during Winter Storm
Uri in February 2021 and (iii) increased gas and NGL prices during the first
quarter of 2021 that resulted in increased gas processing costs for those
contractual volumes retained by the processor as payment for their services; and
•Net natural gas plant income per BOE decreased primarily due to processing
facility revenues being impacted by Winter Storm Uri, partially offset by
improved gas and NGL prices.
Production and ad valorem taxes.

The increase in production taxes per BOE for the three months ended March 31,
2021, as compared to the same period in 2020, was primarily due to increases in
oil, NGL and gas commodity prices. The decrease in ad valorem taxes per BOE for
the three months ended March 31, 2021, as compared to the same period in 2020,
was primarily due to lower prior year commodity prices for which ad valorem

The decrease in DD&A per BOE and depletion expense per BOE was primarily due to
incremental additions to proved reserves due to new wells from the Company's
successful Spraberry/Wolfcamp horizontal drilling program, improved commodity
prices and recognizing the proved reserves attributable to the Parsley
Acquisition.

The increase in geological and geophysical costs for the three months ended
March 31, 2021, as compared to the same period in 2020, was primarily due to
relicensing certain seismic data in connection with the Parsley Acquisition.
During the three months ended March 31, 2021, the Company drilled and evaluated
106 exploration/extension wells, of which 100 percent were successfully
completed as discoveries. During the same period in 2020, the Company drilled
and evaluated 83 exploration/extension wells, of which 100 percent were
successfully completed as discoveries.

The change in noncash general and administrative expense for the three months
ended March 31, 2021, as compared to the same period in 2020, 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.
The increase in cash general and administrative expense for the three months
ended March 31, 2021, as compared to the same period in 2020, was primarily due
to the reinstatement of certain employee benefits during 2021 that were
temporarily suspended during 2020 in response to the COVID-19 pandemic.

The increase in cash interest expense during the three months ended March 31,
2021, as compared to the same respective period in 2020, is primarily due to (i)
the changes in long-term debt as a result of the Parsley Acquisition (see
"Liquidity and Capital Resources" below for further information) and (ii) the
issuance in May 2020 and August 2020, respectively, of $1.3 billion of the
Convertible Notes and $1.1 billion of 1.90% senior notes due 2030, partially
offset by (a) the partial repayment of $360 million of the Company's 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 and (b) the repayment of its 3.45% senior
notes that matured in January 2021.
The weighted average cash interest rate on the Company's indebtedness for the
three months ended March 31, 2021 was 2.0 percent, as compared to 4.4 percent
for the same period in 2020. See   Note 7   of Notes to Consolidated Financial
Statements in "Item 1. Financial Statements" for additional information.
Other expense.
                                  Three Months Ended March 31,
                                                            2021       2020      Change

The increase in other expense during the three months ended March 31, 2021, as
compared to the same respective period in 2020, was primarily due to the
following:
•$80 million of losses related to the Company's fulfillment of certain firm gas
purchase commitments during Winter Storm Uri in February 2021; and
•$197 million of one-time Parsley Acquisition related costs for the three months
ended March 31, 2021; as compared to
•a $69 million charge for estimated deficiency payments related to the Company's
South Texas Divestiture for the three months ended March 31, 2020.

The change in income tax benefit (provision) during the three months ended
March 31, 2021, as compared to the same period in 2020, was primarily due to a
$449 million decrease in income before income taxes. The Company evaluates and
updates its annual effective income tax rate on an interim basis based on
current and forecasted earnings and tax laws. The mix and timing of the
Company's actual earnings compared to annual projections can cause interim
effective tax rate fluctuations. The Company's interim effective tax rate for
the three months ended March 31, 2021 differed from the U.S. statutory rate of
21 percent primarily due to forecasted state income taxes. See   Note     15
of Notes to Consolidated Financial Statements included in "Item 1. Financial
Statements" for additional information.
Liquidity and Capital Resources
Liquidity. 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,
(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, (v) working capital obligations and (vi) funding the cash
portion of the consideration in the DoublePoint Acquisition and retiring the
outstanding balance under the DoublePoint credit facility. 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.
During the three months ended March 31, 2021, the Company enhanced its liquidity
position by refinancing a portion of the debt acquired in the Parsley
Acquisition, issuing new debt and increasing borrowing capacity under the
Company's Credit Facility 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 funded the purchase of DoublePoint with $1 billion of cash and by
issuing 27.2 million shares of the Company's common stock. The Company also
repaid DoublePoint's credit facility of $241 million on the acquisition date. In
conjunction with the DoublePoint Acquisition, the Company delivered a notice of
conditional redemption for all of the Notes. The redemption date for the Notes
provided in the notice of conditional redemption is expected to be on May 18,
2021 (the "Redemption Date"). The redemption of the Notes is conditioned upon
the successful completion by Pioneer of an investment grade public debt
financing transaction of at least $650 million by the Redemption Date; provided
that at the discretion of the Issuers, the Redemption Date may be delayed until
such time as any or all conditions shall be satisfied or waived (provided that
in no event shall such Redemption Date be delayed to a date later than July 3,
2021).

Capital resources. As of March 31, 2021, the Company had no outstanding
borrowings under its Credit Facility, leaving $2.0 billion of unused borrowing
capacity. The Company was in compliance with all of its debt covenants as of
March 31, 2021. The Company also had unrestricted cash on hand of $668 million
as of March 31, 2021.
Cash flows from operating, investing and financing activities are summarized
below.
                                                            Three Months Ended March 31,

Net cash provided by (used in) financing activities     $          (806)    

$ 9 $ 815




Operating activities. The decrease in net cash flow provided by operating
activities for the three months ended March 31, 2021, as compared to the same
period in 2020, was primarily due to (i) additional cash used in derivative
activities, (ii) increased accounts receivables and commodity inventories as a
result of higher commodity prices, (iii) one-time cash Parsley transaction costs
and (iv) cash paid to fulfill certain gas commitments during Winter Storm Uri,
partially offset by an increase in accounts payable as a result of increased
drilling and operational activity and an increase in oil and gas revenues due to
the aforementioned increase in commodity prices.
Investing activities. The decrease in net cash used in investing activities for
the three months ended March 31, 2021, as compared to the same period in 2020,
was primarily a result of (i) the Company's cost reduction efforts with
decreases in additions to oil and gas properties and additions to other assets
and other property and equipment of $175 million and $19 million, respectively,
(ii) $117 million of cash acquired in the Parsley Acquisition and (iii) an
increase in proceeds from disposition of assets of $22 million primarily related
to the sale of the Company's well services business.
Financing activities. The Company's significant financing activities are as
follows:
•2021: The Company (i) received proceeds from the January 2021 Senior Notes
Offering, net of $24 million of issuance costs and discounts, of $2.5 billion,
(ii) repaid $140 million associated with the maturity of its 3.45% senior notes
due in January 2021, (iii) used the proceeds from the January 2021 Senior Notes
Offering to 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, (iv) paid $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, (v) repaid Parsley's credit facility, which had an outstanding
balance of $397 million, (vi) paid $140 million of other liabilities and (vii)
paid dividends of $91 million.
•2020: The Company (i) borrowed $800 million under the Credit Facility, (ii)
repaid $450 million associated with the maturity of its 7.50% senior notes,
(iii) paid $146 million of other liabilities, (iv) purchased $122 million of
treasury stock and (v) paid dividends of $73 million.
Dividends/distributions. During the three months ended March 31, 2021, the
Company paid dividends of $91 million, or $0.55 per share. In February 2021, the
board of directors declared a quarterly cash dividend of $0.56 per share on the
Company's outstanding common stock, payable on April 14, 2021, to stockholders
of record on March 31, 2021. 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 that 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. As of March 31, 2021, 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 (a)
derivative contracts that are sensitive to future changes in commodity prices or
interest rates, (b) gathering, processing (primarily treating and fractionation)
and transportation commitments on uncertain volumes of future throughput and (c)
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
                                       41

PIONEER NATURAL RESOURCES COMPANY
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 "Contractual obligations" below and   Note 10 

of


Notes to Consolidated Financial Statements included in "Item 1. Financial
Statements" for additional information.
Contractual obligations. The Company's contractual obligations include long-term
debt, 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.
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 and completion 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's commodity and marketing derivative contracts are periodically
measured and recorded at fair value and continue to be subject to market and
credit risk. As of March 31, 2021, these contracts represented net liabilities
of $970 million. 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 March 31, 2021. See   Note 5   of Notes to Consolidated Financial
Statements included in "Item 1. Financial Statements" and "  Item 3.
Quantitative and Qualitative Disclosures About Market Risk  " for additional
information.
New Accounting Pronouncements
The effects of new accounting pronouncements are discussed in   Note 2   of
Notes to Consolidated Financial Statements included in "Item 1. Financial
Statements."
ITEM 3.     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 selling purchased oil
and gas outside of the Permian Basin. The following quantitative and qualitative
information is provided about financial instruments to which the Company was a
party as of March 31, 2021, 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 March 31, 2021, the Company had no variable rate debt
outstanding under the Credit Facility and, consequently, no related exposure to
interest rate risk. As of March 31, 2021, the Company had $6.2 billion of fixed
rate long-term debt outstanding with a weighted average effective interest rate
of 2.0 percent. Although changes in interest rates may affect the fair value of
the Company's fixed rate long-term debt, any changes would not impact earnings
or expose the Company to the risk of cash flow losses. The Company did not have
any interest rate derivative instruments outstanding as of March 31, 2021;
however, it may enter into such instruments in the future to mitigate interest
rate risk. See   Note 4   and   Note 7   of Notes to Consolidated Financial
Statements included in "Item 1. Financial Statements" for additional
information.
Commodity price risk. The Company's primary market risk exposure is related to
the price it receives from the sale of its oil, NGLs 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
                                       42

market index prices. Reducing the Company's exposure to price volatility helps
secure funds to be used in its capital program and to fund general working
capital needs, debt obligations, dividends and share repurchases, among other
uses. The Company mitigates its commodity price risk through the use of
derivative financial instruments and sales of purchased oil and gas.
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 commodity price forecast 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 or minimize loss
positions if it is anticipated that the commodity price forecast is expected to
improve. Proceeds, if any, can be used for the purpose of funding the Company's
capital program, general working capital needs, debt obligations, dividends and
share repurchases, among other uses. While derivative positions limit the
downside risk of adverse price movements, they also limit future revenues from
upward price movements. The Company manages commodity price risk with the
following types of commodity 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, alternatively, 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 allow participation in higher
prices when prices close above the floor price.
The Company has entered into commodity derivative contracts for a portion of
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 on additional volumes 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 1. Financial Statements" for a description of the Company's
open derivative positions and additional information.
Sales of purchased oil and gas. 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 whereby 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 began on January 1, 2021 and
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. Similar to sales of purchased
commodities, these 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.

PIONEER NATURAL RESOURCES COMPANY
The Company's commodities are sold to various purchasers who must be
prequalified under the Company's credit risk 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 commodities 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 1. Financial
Statements" for additional information.
