BUSINESS STRATEGY
Our VISION is to be the premier exploration and production company, contributing to global progress by helping meet the world’s energy needs.
Our MISSION is to grow in an innovative, safe, environmentally responsible, and profitable manner for the long-term benefit of our stakeholders.
Our STRATEGY is to take a differentiated approach to the exploration and production of cost-advantaged hydrocarbons through innovation, technology, optimization, continuous improvement, and relentless focus on costs to deliver top-tier, long-term returns.

Rigorous management of the Company’s asset portfolio plays a key role in optimizing shareholder value over the long term. Over the past several years, Apache has entered into a series of transactions that have upgraded its portfolio of assets, enhanced its capital allocation process to further optimize investment returns, and increased focus on internally generated exploration with full-cycle, returns-focused growth. These efforts included the monetization of certain non-strategic assets, including gas-weighted properties in the Midcontinent/Gulf Coast region and selling other non-core leasehold positions. The Company made strategic decisions to allocate the proceeds of these divestitures to more impactful development opportunities across its portfolio and exploration efforts in Suriname. In addition, in November 2018, the Company completed a transaction with Altus Midstream Company and its then wholly-owned subsidiary, Altus Midstream LP, to create a publicly-traded midstream C-corporation.
Apache’s U.S. upstream oil and gas assets are complemented by its international assets in Egypt and the North Sea, each of which adds to the Company’s inventory of exploration and development opportunities. Apache’s diverse international portfolio and asset inventory includes, at scale, both conventional and unconventional resources covering crude oil, rich natural gas with NGLs, and lean natural gas.
During 2020, the global economy and the energy industry were deeply impacted by the effects of the COVID-19 pandemic and related third-party actions. Uncertainty in the oil markets and the negative demand implications resulting from the COVID-19 pandemic continue to weigh on commodity prices. As with previous changes in a volatile price environment, Apache has continued to respond quickly and decisively, taking the following strategic actions:
Establishing and implementing a wide range of fit-for-purpose protocols and procedures to ensure a safe and productive work environment across the Company’s diversified global onshore and offshore operations.
Reducing upstream capital investments by over 50 percent from the comparative prior-year period, including eliminating nearly all U.S. drilling and completion activity by May 2020 and reducing planned activity in Egypt and the North Sea.
Decreasing the Company’s dividend by 90 percent beginning in the first quarter of 2020, preserving approximately $340 million of cash flow on an annualized basis and strengthening liquidity.
Completing an organizational redesign focused on centralizing certain operational activities in an effort to capture greater efficiencies, achieving an estimated cost savings of $400 million annually.
Conducting, on a continuous basis, price sensitivity analyses and operational evaluations of producing wells across the Company’s portfolio that allow for a methodical and integrated approach to production shut-ins and curtailments with a focus on preserving cash flows in a distressed price environment and protecting the Company’s assets.
The Company remains committed to its longer-term objectives: (1) to maintain a balanced asset portfolio, including advancement of ongoing exploration and appraisal activities offshore Suriname; (2) to invest for long-term returns over production growth; and (3) to budget conservatively to generate excess cash flow that can be directed on a priority basis to debt reduction.
For a more in-depth discussion of the Company’s 2020 results, divestitures, strategy, and its capital resources and liquidity, please see Part II, Item 7—Management’s Discussion and Analysis of Financial Condition and Results of Operations of this Annual Report on Form 10-K.

In 2020,2023, Apache’s U.S. upstream oil and gas operations contributed approximately 5851 percent of production, 38 percent of oil and 67gas revenues, and 69 percent of estimated year-end proved reserves. Apache has access to significant liquid hydrocarbons across its 4.93.4 million gross acres (2.5(1.7 million net acres) in the U.S., 7874 percent of which are undeveloped.
The Company’s U.S. assets are primarily located in the Permian Basin in West Texas and New Mexico, including the Permian sub-basins: Midland Basin, Central Basin Platform/Northwest Shelf, and Delaware Basin. Examples of shale plays being developed within these sub-basins include the Woodford, Barnett, Pennsylvanian, Cline, Wolfcamp, Bone Spring, and Spraberry. Apache is one of the largest operators in the Permian Basin, operating more than 7,000approximately 5,000 gross oil and gas wells across its acreage, with additional interests in over 4,000less than 3,000 non-operated wells. Approximately six percent of the Company’s net acreage position in the Permian Basin is on federal onshore lands. Apache also has operations located in the Eagle Ford shale and Austin Chalk areas of Southeast Texas, offshore in the Gulf of Mexico, and along the Gulf of Mexico,Coast in the areas onshore and offshore southSouth Texas and Louisiana.
Highlights of the Company’s operations in the U.S. include:

With the improvement in oil prices, theThe Company is returningcommitted to maintaining a modestsafe, steady, and efficient level of activity in the U.S.as part of its three-year capital investment program. For 2021, the Company is currently running one drilling rig in the Permian Basin and plans to add a second rig in the middle of the year. In addition, the Company recently added a rig in the Austin Chalk oil play to retain core acreage positions and perform targeted tests. The Company also resumed completions activity in the Permian Basin during the fourth quarter of 2020 and began completing previously drilled but uncompleted wells in response to significantly lower service costs. As with prior periods,2024, the Company will continue to monitor commodity prices and will adjustbudget its capital budget accordinglyprogram at levels to protectfund activity necessary to offset inherent declines in production and proved oil and natural gas reserves. Future rig activity levels and drilling targets will be dependent on the success of the Company’s drilling program and its cash flows.ability to add reserves economically.
U.S. Marketing In general, most of the Company’sThe Company sells its U.S. natural gas production is soldat liquid index sales points within the U.S., at either monthly or daily index-based prices. In addition, to satisfy a delivery commitment that began in 2023, the Company purchases third party natural gas to sell and deliver to a U.S. LNG export facility. The tenor of the Company’s sales contracts span from daily to multi-year transactions. Natural gas is sold to a variety of customers that include local distribution, utility, and midstream companies, as well as end-users, marketers, and integrated major oil companies. Apache strives to maintain a diverse client portfolio, which is intended to reduce the concentration of credit risk. Apache predominantly sells its natural gas production within the United States, including to U.S. LNG export facilities, although a portion is sold to markets in Mexico.

Apache primarily markets its U.S. crude oil production to integrated major oil companies, marketing and transportation companies, and refiners based on West Texas Intermediate (WTI) pricing indices (e.g., WTI Houston, West Texas Sour (WTS), WTI Midland, or WTIWest Texas Light (WTL) Midland) and some predominately Brent related international pricing indices, adjusted for quality, transportation, and a market-reflective differential. Apache’s objective is to maximize the value of crude oil sold by identifying the best markets and most economical transportation routes available to move the product. Sales contracts are generally 30-day evergreen contracts that renew automatically until canceled by either party. These contracts provide for sales that are priced daily at prevailing market prices. Also, from time to time, the Company will enter into physical term sales contracts. These term contracts typically have a firm transportation commitment and often provide an opportunity for higher than prevailing market prices.
Apache’s U.S. NGL production is sold under contracts with prices based on Gulf Coast supply and demand conditions, less the costs for transportation and fractionation, or on a weighted-average sales price received by the purchaser.
U.S. Delivery Commitments The Company has long-term delivery commitments for natural gas and crude oil whichthat require Apache to deliver an average of 232161 Bcf of natural gas per year for the period from 20212024 through 2029, at variable, market-based pricing and deliver an average of 6.849 Bcf of natural gas per year for the period from 2030 through 2037, and an average of 4.9 MMbbls of crude oil per year for the period from 20202024 through 2025, in each case, at variable, domestic and/or international, market-based pricing.
Apache currently expects to fulfill its delivery commitments with production from its proved reserves, production from continued development, and/or spot market purchases as necessary.third-party purchases. Apache may also enter into contractual arrangements to reduce its delivery commitments. The Company has not experienced any significant constraints in satisfying the committed quantities required by its delivery commitments.

In 2020,2023, international assets contributed 4249 percent of Apache’s production and 5662 percent of its oil and gas revenues. Approximately 3331 percent of estimated proved reserves at year-end 2023 were located outside the U.S.
Apache has two international locations with ongoing development and production operations:
Egypt, which includes onshore conventional assets located in Egypt’s Western Desert; and
the North Sea, which includes offshore assets based in the United Kingdom.U.K.
The Company also has an active offshore exploration program and planned appraisal operations ongoing in Suriname.
Egypt Apache has 25 yearsdecades of exploration, development and operations experience in Egypt and is one of the largest acreage holders in Egypt’s Western Desert. At year-end 2020,2023, the Company held 5.25.3 million gross acres in 24six separate concessions. The Company’s acreage is primarily held under one concession agreement that resulted from the ratification of a new merged concession agreement (MCA) with the Egyptian Ministry of Petroleum and the Egyptian General Petroleum Corporation (EGPC). The MCA, which has an effective date of April 1, 2021, consolidated 98 percent of gross acreage and 90 percent of gross production under one concession agreement and refreshed the existing development lease terms for 20 years and exploration leases for 5 years. The consolidated concession has a single cost recovery pool to provide improved access to cost recovery, a fixed 40 percent cost recovery limit, and a fixed profit-sharing rate of 30 percent for all the Company’s production covered under the concession. Development leases within concessions currently have expiration dates ranging from 1 to 20 years, with extensions possible for additional commercial discoveries or on a negotiated basis. Approximately 6867 percent of the Company’s gross acreage in Egypt is undeveloped, providing Apache with considerable exploration and development opportunities for the future.

Apache’s Egypt operations are conducted pursuant to production sharingproduction-sharing contracts (PSCs). Under the terms of the Company’s PSCs, the Company is the contractor partner (Contractor) with EGPC and bears the risk and cost of exploration, development, and production activities. In return, if exploration is successful, the Contractor receives entitlement to variable physical volumes of hydrocarbons, representing recovery of the costs incurred and a stipulated share of production after cost recovery. Additionally, the Contractor’s income taxes, which remain the liability of the Contractor under domestic law, are paid by Egyptian General Petroleum Corporation (EGPC)EGPC on behalf of the Contractor out of EGPC’s production entitlement. Income taxes paid to the Arab Republic of Egypt on behalf of the Contractor are recognized as oil and gas sales revenue and income tax expense and are reflected as production and estimated reserves. Because Contractor cost recovery entitlement and income taxes paid on its behalf are determined as a monetary amount, the quantities of production entitlement and estimated reserves attributable to these monetary amounts will fluctuate with commodity prices. In addition, because the Contractor income taxes are paid by EGPC, the amount of the income tax has no economic impact on Apache’s Egypt operations despite impacting Apache’s production and reserves.
In conjunction with the ratification of the MCA, Apache modified partnership agreements for certain consolidated subsidiaries. The Apache subsidiary that is the sole Contractor under the MCA is owned by an Apache-operated joint venture. For all periods presented, Sinopec International Petroleum Exploration and Production Corporation (Sinopec) owned a one-third minority participation in the Company’s consolidated Egypt oil and gas business as a noncontrolling interest. Under the modified partnership agreements, APA owns a noncontrolling interest participation in the remaining two-thirds of the Company’s consolidated Egypt oil and gas business.
The Company’s estimated proved reserves in Egypt are reported under the economic interest method and exclude the host country’s share of reserves. In addition, Sinopec International Petroleum Exploration and Production Corporation (Sinopec) holds a one-third minority participation interest in Apache’s oil and gas operations in Egypt. Apache’s Egypt assets, including the one-thirdAPA and Sinopec’s noncontrolling interest,interests, contributed 2837 percent of 20202023 production and 2022 percent of 2023 year-end estimated proved reserves. Excluding the impacts of theAPA and Sinopec’s noncontrolling interest,interests, Egypt contributed 2016 percent of 20202023 production and 1513 percent of 2023 year-end estimated proved reserves.
In 2020,2023, the Company drilled 3675 gross development and 2548 gross exploration wells in Egypt. A key component of the Company’s success has been the ability to acquire and evaluate 3-D seismic surveys that enable Apache’s technical teams to consistently high-grade existing prospects and identify new targets across multiple pay horizons in the Cretaceous, Jurassic, and deeper Paleozoic formations. The Company has completed seismic surveys covering over 3three million acres, which has led to date and continues torecent discoveries that build and enhance itsthe Company’s drilling inventory in Egypt, supplemented with recent seismic acquisitions and new play concept evaluations, on both new and existing acreage.
For 2021, theEgypt. The Company plans to continue running a five rig drilling program for the year with a goal of stabilizing production and ultimately return Egypt to growth, both of which would require additional rigs. Apache is positioned to quickly flex spending in Egypt as conditions warrant and will continue to monitor oil pricesfocus on driving efficiencies and cash flow formanaging costs under the appropriate time to pursue increased activity.MCA.
North Sea Apache has interests in approximately 516,000292,000 gross acres in the U.K. North Sea. These assets contributed 1412 percent of Apache’s 20202023 production and approximately 139 percent of year-end 2023 estimated proved reserves.
Apache entered the North Sea in 2003 after acquiring an approximate 97 percent working interest in the Forties field (Forties). Since acquiring Forties, Apache has actively invested in the assets and has established a large inventory of drilling prospects through successful exploration programs and the interpretation of 4-D seismic. Building upon its success in Forties, inIn 2011, Apache acquired Mobil North Sea Limited, providing the Company with additional exploration and development opportunities in the North Sea across numerous fields, includingwhich included operated interests in the Beryl, Ness, Nevis, Nevis South, Skene, and Buckland fields and a non-operated interest in the Maclure field. Apache also has a non-operated interest in the Nelson field acquired in 2011. The Beryl field, which is a geologically complex area with multiple fields and stacked pay potential, provides for significant exploration opportunity. The North Sea assets plays a strategic role in Apache’s portfolio by providing competitiveDuring the second quarter of 2023, as part of the Company’s focus on capital allocation to optimize investment opportunities and potential reserve upside with high-impact exploration potential, near existing infrastructure.

The Company’s Storr exploration discovery came on-line in the fourth quarter of 2019,investment program there is now directed toward safety, base production management, and its second well at Garten came on-line in the first quarter of 2020. The first well at the Company’s Storr development is a high-rate gas condensate well that is tied back to existing infrastructure at the Beryl Alpha platform. The Garten #2 well encountered approximately 1,200 feet of net pay,asset maintenance and Apache holds a 100 percent working interest in the Garten complex. Both of these exploration discoveries coming on-line, coupled with the modest drilling activity level for the year, increased the Company’s production in the North Sea compared to 2019.
In 2021, the expected capital program for the North Sea remains relatively unchanged to the prior year with one floating rig and one platform crew.

International Marketing  Apache’s natural gas production in Egypt is sold to EGPC primarily under an industry-pricing formula, a sliding scale based on Dated Brent crude oil with a minimum of $1.50 per MMBtu and a maximum of $2.65 per MMBtu, plus an upward adjustment for liquids content. Crude oil production is sold to third parties in the export market or to EGPC when called upon to supply domestic demand. Oil production sold to third parties is sold and exported from one of two terminals on the northern coast of Egypt. Oil production sold to EGPC is sold at prices related to the export market.
Apache’s North Sea crude oil production is sold under term, entitlement volume contracts and spot variable volume contracts with a market-based index price plus a differential to capture the higher market value under each type of arrangement. Natural gas from the Beryl field is processed through the Scottish Area Gas Evacuation (SAGE) gas plant, operated by Ancala Midstream Acquisitions Limited. Natural gas is sold to a third party at the St. Fergus entry point of the national grid on a National Balancing Point index price basis. The condensate mix from the SAGE plant is processed further downstream. The split streams of propane, butane, and condensate are sold separately on a monthly entitlement basis at the Braefoot Bay terminal using index pricing less transportation.

New Ventures Apache’s international New Ventures team provides exposure to new growth opportunities by looking outside of the Company’s traditional core areas and targeting higher-risk, higher-reward exploration opportunities located in frontier basins as well as new plays in more mature basins.
In December 2019, Apache entered into a joint venture agreement with Total S.A. to explore and develop Block 58 offshore Suriname. The Company holds a 50 percent working interest in Block 58, which comprises approximately 1.4 million gross acres in water depths ranging from less than 100 meters to more than 2,100 meters. Starting in late 2019 and throughout 2020, Apache drilled the first three wells in the block, the Maka Central-1, Sapakara West-1, and Kwaskwasi-1, all of which successfully tested for the presence of hydrocarbons in multiple stacked targets in the upper Cretaceous-aged Campanian and Santonian intervals, encountering both oil and gas condensate.
In January 2021, Apache and Total S.A announced the fourth consecutive discovery in Block 58 at Keskesi East-1, which confirmed oil in the eastern portion of the block. The Keskesi East-1 well is continuing to drill to deeper targets. In accordance with the joint venture agreement, Apache transferred operatorship of Block 58 to Total S.A. on January 1, 2021. Apache will continue to operate the Keskesi exploration well until completion of drilling operations.
Drilling Statistics
Worldwide in 2020,2023, Apache drilled or participated in drilling 132230 gross wells, with 119198 wells (90(86 percent) completed as producers. Historically, Apache’s drilling activities in the U.S. have generally concentrated on exploitation and extension of existing producing fields rather than exploration. As a general matter, the Company’s operations outside of the U.S. focus on a mix of exploration and development wells. In addition to wells completed during 2023, at year-end 2023, a number of wells had not yet reached completion: 8069 gross (63.1(65.5 net) in the U.S., 2449 gross (23.5(49.0 net) in Egypt, 1and 3 gross (1(2.5 net) in the North Sea, and 1 gross (0.5 net) in Suriname.

Additionally, the Company has exploration interests in Suriname consisting of 390,000 net undeveloped acres in Block 53 set to expire in 2022 contingent on planned drilling activity. The Company has acquired 3-D seismic surveys over all acreages. No oil and gas reserves have been recorded on this undeveloped acreage.
Estimated Proved Reserves and Future Net Cash Flows
Proved oil and gas reserves are those quantities of natural gas, crude oil, condensate, and NGLs, which by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible from a given date forward, from known reservoirs, and under existing economic conditions, operating methods, and government regulations. Estimated proved developed oil and gas reserves can be expected to be recovered through existing wells with existing equipment and operating methods. The Company reports all estimated proved reserves held under production-sharing arrangements utilizing the “economic interest” method, which excludes the host country’s share of reserves.
Estimated reserves that can be produced economically through application of improved recovery techniques are included in the “proved” classification when successful testing by a pilot project or the operation of an active, improved recovery program using reliable technology establishes the reasonable certainty for the engineering analysis on which the project or program is based. Economically producible means a resource that generates revenue that exceeds, or is reasonably expected to exceed, the costs of the operation. Reasonable certainty means a high degree of confidence that the quantities will be recovered. Reliable technology is a grouping of one or more technologies (including computational methods) that has been field-tested and has been demonstrated to provide reasonably certain results with consistency and repeatability in the formation being evaluated or in an analogous formation. In estimating its proved reserves, Apache uses several different traditional methods that can be classified in three general categories: (1) performance-based methods; (2) volumetric-based methods; and (3) analogy with similar properties. Apache will, at times, utilize additional technical analysis, such as computer reservoir models, petrophysical techniques, and proprietary 3-D seismic interpretation methods, to provide additional support for more complex reservoirs. Information from this additional analysis is combined with traditional methods outlined above to enhance the certainty of the Company’s reserve 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 recompletion. 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 reserves only if a development plan has been adopted indicating that they are scheduled to be drilled within five years, unless specific circumstances justify a longer time period.

As of December 31, 2020,2023, the Company’s proved developed reserves totaled 798707 MMboe and estimated PUDproved undeveloped (PUD) reserves totaled 7666 MMboe, or approximately 9 percent of worldwide total proved reserves. Apache has elected not to disclose probable or possible reserves in this filing. The Company does not have anyhad no fields that containcontained 15 percent or more of its total proved reserves for the year ended December 31, 2023. The Company had one field that contained 15 percent or more of its total proved reserves for each of the years ended December 31, 2020, 2019,2022 and 2018.2021.
During 2020,2023, the Company added 78approximately 96 MMboe from extensions, discoveries, and other additions. The Company recorded 79 MMboe of proved reserves through exploration and development adds in the U.S., comprising 67 MMboe in the Permian Basin, 10 MMboe in the Delaware Basin, and 2 MMboe in the Texas Gulf Coast. Drilling programs for the Permian and Delaware Basins include the Wolfcamp, Bone Spring and Spraberry with the Austin Chalk as the primary focus for the Texas Gulf Coast. International operations contributed 16 MMboe of exploration and development adds, with Egypt contributing 15 MMboe from onshore exploration and appraisal activity partially offset byprimarily in the Khalda Area and 1 MMboe from the North Sea. The Company had combined downward revisions of previously estimated reserves of 45 MMboe.

Estimated future net cash flows were calculated using a discount rate of 10 percent per annum, end of period costs, and an unweighted arithmetic average of commodity prices in effect on the first day of each of the previous 12 months, held flat for the life of the production, except where prices are defined by contractual arrangements.
Proved Undeveloped Reserves
The Company’s total estimated PUD reserves of 7666 MMboe as of December 31, 2020,2023, decreased by 4210 MMboe from 11876 MMboe of PUD reserves reported at theyear end of 2019.2022. During the year,2023, Apache converted 3531 MMboe of PUD reserves to proved developed reserves through development drilling activity. In the U.S., Apache converted 2529 MMboe, with the remaining 102 MMboe in Apache’sits international areas. Apache did not sell any PUD reservesThe Company had no sales nor purchases in the U.S. and did not acquire anyplace related to PUD reserves during the year.2023. Apache added 4365 MMboe of new PUD reserves through extensions and discoveries. Apache did not recognize an upward engineering revision in proved undeveloped reserves during the year. Downward revisions included 1totaled 44 MMboe, comprising 4 MMboe associated with engineering and interest revisions, 4312 MMboe associated with revised development plans, and 628 MMboe associated with product prices.
During the year,2023, a total of approximately $339$318 million was spent on projects associated with proved undeveloped reserves. A portion of Apache’s costs incurred each year relate to development projects that will convert undeveloped reserves to proved developed reserves in future years. During 2020,2023, Apache spent approximately $251$264 million on PUD reserve development activity in the U.S. and $88$54 million in the international areas. As of December 31, 2020,2023, Apache had no material amounts of proved undeveloped reserves scheduled to be developed beyond five years from initial disclosure.
Preparation of Oil and Gas Reserve Information
Apache’s reported reserves are reasonably certain estimates which, by their very nature, are subject to revision. These estimates are reviewed throughout the year and revised either upward or downward, as warranted.
Apache’s proved reserves are estimated at the property level and compiled for reporting purposes by a centralized group of experienced reservoir engineers that is independent of the operating groups. These engineers interact with engineering and geoscience personnel in each of Apache’s operating areas and with accounting and marketing employees to obtain the necessary data for projecting future production, costs, net revenues, and ultimate recoverable reserves. All relevant data is compiled in a computer database application, to which only authorized personnel are given security access rights consistent with their assigned job function. Reserves are reviewed internally with senior management and presented to Apache’s board of directors (the Board of DirectorsDirectors) in summary form on a quarterly basis.

The estimate of reserves disclosed in this Annual Report on Form 10-K is prepared by the Company’s internal staff, and the Company is responsible for the adequacy and accuracy of those estimates. The Company engages Ryder Scott Company, L.P. Petroleum Consultants (Ryder Scott) to conduct a reserves audit, which includes a review of ourthe Company’s processes and the reasonableness of ourthe Company’s estimates of proved hydrocarbon liquid and gas reserves. The Company selects the properties for review by Ryder Scott based primarily on relative reserve value. The Company also considers other factors such as geographic location, new wells drilled during the year, and reserves volume. During 2020,2023, the properties selected for each country ranged from 84 to 86all countries represented 88 percent of the total future net cash flows discounted at 10 percent. These properties also accounted for 8491 percent of the value of Apache’s international proved reserves and 9495 percent of the value of Apache’s new wells drilled worldwide. In addition, all fields containing five percent or more of the Company’s total proved reserves volume were included in Ryder Scott’s review. The review covered 8183 percent of total proved reserves on a boe basis.
The percentages of total estimated proved reserves values, calculated as future net cash flows discounted at 10 percent, and volumes, on a boe basis, covered by Ryder Scott’s reviewreviews for the years 2020, 2019,2023, 2022, and 2018 covered 85, 87, and 86 percent, respectively, of the value and 81, 85, and 83 percent, respectively, of the volume of the Company’s worldwide estimated proved reserves.

HUMAN CAPITAL MANAGEMENT
As a company, Apache believes its people are its greatest asset. Exploring what’s possible at Apache is the union of curiosity, intellect, and hard work, built on mutual respect, honesty, integrity, and a keen sense of responsibility for the Company’s team, community, and the environment. With respect to its employees, the Company is focused on health and safety, diversity and inclusion, and total rewards, so that joining the Apache family is a positive experience for all.

In 2020, a major redesign of Apache’s organizational structure and operations and the global COVID-19 pandemic had significant impacts on the Company’s human capital management. In connection with the organizational and operational redesign and changes in the economic environment in which Apache operates, the Company offered voluntary retirement packages, made reductions-in-force, and began limiting hiring to critical business roles. In response to the global COVID-19 pandemic, Apache implemented significant operating environment changes that the Company determined were in the best interest of its employees and complied with government regulations. These changes include having the vast majority of Apache’s employees working from home, while implementing additional safety protocols and procedures for essential employees continuing critical on-site work.
Oversight and Management
Apache’s Board of Directors has three standing committees, each devoted to a separate aspect of risk oversight. The Corporate Governance and Nominating (CG&N) Committee, the Audit Committee, the Management Development and Compensation (MD&C) Committee, and/or the full Board of Directors receive regular reports on certain human capital matters, including the Company’s diversity and inclusion programs and initiatives.
The MD&C Committee oversees Apache's compensation programs, leadership development and succession planning strategies, and seeks continuous improvement in the diversity and inclusion practices used in developing and deploying these processes.
The Audit Committee oversees the integrity of the Company's financial statements and monitors human capital management risk against compliance with legal and regulatory requirements.
The CG&N Committee oversees the nomination of candidates for election to the Board of Directors, the annual Board of Directors evaluation process, corporate governance and environmental, social, and governance (ESG) issues, as well as the Company’s annual sustainability report.
Reports and recommendations made to the Board of Directors and its committees are part of the framework that ensures the Company’s daily actions and decisions are guided by its core values, including upholding the health and safety of Apache’s team, stakeholders, and communities, investing in its workforce, ensuring environmental responsibility, and acting ethically and with integrity.
COVID-19 Response
During the early stages of the pandemic, Apache called upon its Crisis Management Team to lead and coordinate the Company's overall COVID-19 pandemic response. This team led efforts to develop and monitor mitigation and business continuity plans, track all relevant country, state and local government guidelines, directives and regulations, develop and adopt work-from-home plans, implement safe working protocols for production teams, assess and implement appropriate return-to-office protocols, and provide timely and transparent communications to global employees and key stakeholders.
In response to the COVID-19 pandemic, Apache began providing the following benefits to its employees:
Covering the cost of COVID-19 testing at the Company’s onsite testing events and through expanded insurance coverage;
Expanding telehealth benefits;
Promoting mental health and well-being plans;
Implementing enhanced hardship distributions and loan eligibility and repayment terms in the Apache 401(k) Savings Plan; and
Providing additional paid sick leave for quarantined employees.

Employee Profile
As of December 31, 2020, Apache had approximately 2,272 full-time equivalent employees in locations across the organization as follows:
Employees
United States1,430 
United Kingdom598 
Egypt237 
Suriname
Total employees2,272 
The employment of approximately 637 employees globally were impacted by involuntary reductions-in-force in 2020. The impacted employees were provided severance packages that included Company-paid benefits and outplacement services. The voluntary workforce turnover for 2020 was 9.6 percent.
As of year-end 2020, Apache’s global workforce was 22.1 percent female and 77.9 percent male, and women represented 17.6 percent of leadership (defined as supervisor level and above or equivalent). In the U.S., Apache’s workforce self-identified as 66.9 percent White, 6 percent Black, 6.8 percent Asian, 18.6 percent Hispanic, and 1.7 percent other. For the Company’s U.S. leadership, the breakdown was 78 percent White, 3 percent Black, 6.3 percent Asian, 11.3 percent Hispanic, and 1.4 percent other.
Health and Safety
Safety underpins the Company’s core values and is at the forefront of decision-making at every level of the Apache organization. Apache is committed to driving a safety culture that empowers its team to act as needed to work safely and to stop the job if conditions are deemed unsafe. Apache’s goal is to demonstrate a continual reduction in Occupational Safety and Health Administration (OSHA) recordable incidents year over year. To this end, the Company’s annual OSHA recordable incident rate targets are set at a 10 percent reduction compared to the preceding 3-year average. During the fiscal year ended December 31, 2020, the recordable incident count for the Company declined by 21 percent compared to the fiscal year ended December 31, 2019.
Apache offers a wide range of training programs for employees and contractors to promote their full understanding of, and compliance with, the Company’s health and safety policies and programs and to help build the skills needed to work safely. In addition to providing specific skills, these training programs encourage personal responsibility for safe operating conditions and help build a culture of individual accountability for conducting job tasks in a safe and responsible manner.
A few key highlights from 2020:
Egypt From drilling to driving, safe-work behavior improved dramatically. The joint-venture drilling team had 55 percent fewer injuries in the second half of 2020 as compared to the first half of 2020.
Suriname With the complexities of working during the pandemic, stringent health and safety protocols have kept personnel safe as they rotate offshore. Rewarding excellence, the drilling team and Noble Sam Croft drillship achieved one year without any recordable incidents.
U.K. In an effort to connect teams with management, Apache’s elected safety representatives have increased workforce engagement around offshore operations and safety. New platform meetings put safety at the forefront of conversations about performance, accidents and hazards, industry updates, and valuable topics such as mental health.
U.S. Despite economic pressures and pandemic challenges, U.S. onshore operations and asset teams performed exceptionally. The Southern Midland Basin, Legacy, and Delaware Basin collectively achieved over 800 days without injuries.

Diversity and Inclusion
Diversity and inclusion (D&I) are vital to Apache’s long-term sustainability. The Company is committed to being a workplace where all employees are valued and can thrive with a sense of belonging, not just as an employee, but as a person. This benefits the individual, Apache and the Company’s stakeholders. Apache is better as an organization when various ideas and perspectives are brought to the table. As a part of the Company’s commitment to diversity and inclusion, in August 2020, Apache hired a D&I Lead and partnered with a prominent D&I consultant to better understand where the organization stands in its D&I efforts and to build a D&I strategy that directly supports the Company’s diversity and inclusion goals. To further the Company’s strategy, Apache conducted focus group sessions to gain insight into its employees’ experiences and to better understand its D&I strengths and opportunities. With this feedback in mind, Apache evaluated its recruiting, talent management, and learning efforts to identify and implement changes that would allow for increased employee opportunities, belonging, and workplace diversity.
To showcase a visible commitment, Apache launched a Diversity & Inclusion employee site that provides D&I and allyship trainings and information on how to join and initiate Employee Resource Groups (ERG). Apache currently has four ERGs: the Apache Women’s Network (AWN), Apache Young Professionals’ Network (AYPN), Apache D&I Council, and the newly formed Apache Black Professionals Network (ABPN). These groups encourage cultural awareness, professional development, community outreach, and networking. The Company looks forward to expanding its ERGs to help build employee connections and belonging, support Apache’s community outreach programs, and foster career development. Over the years to come, Apache will continue to actively support employees in forming additional demographic-based groups (e.g., ethnicity, nationality, age, sexual orientation, etc.), as well as interest-based groups (e.g., support, sports, hobbies, etc.).
Apache embraces the idea of continuous improvement in all that it does, and its D&I journey is no different. The Company is committed to continually improving and making changes throughout the organization to foster a more inclusive and diverse workforce.
Total Rewards
Apache’s total rewards are designed to attract, retain, and reward top talent. As part of its compensation philosophy, Apache offers and maintains a robust total compensation package that includes a competitive base salary, industry-leading benefits, and performance-driven incentives. The Company believes that a compensation program with both short-term and long-term incentives provides fair and competitive compensation and aligns employee and stockholder interests. Apache’s incentive compensation programs reward Company and individual performance by incorporating metrics related to Apache’s operations, financial, ESG, and workforce safety initiatives.
In addition to cash and equity compensation, the Company also promotes employee benefits that cultivate a family-friendly work environment and focus on its employees’ overall wellness. Apache’s robust benefits platform ranks among the best in the Company’s industry peer group and includes comprehensive healthcare, retirement benefits, as well as locally relevant well-being benefits.
Recent enhancements in Apache’s benefit offerings for employees include the following:
The U.S. family leave policies include paid time off for all new parents, including adoptive and surrogate parents, and leave for employees providing elder care.
The availability of mental health benefits to all U.S.-based employees and eligible family members, including 16 free sessions with a mental health therapist or coach each year.
A global wellness platform, which encourages and promotes physical, financial, social, and emotional well-being.

RISKS RELATED TO PRICING, DEMAND, AND PRODUCTION FOR CRUDE OIL, NATURAL GAS, AND NATURAL GAS LIQUIDS (NGLs)
The COVID-19 pandemic has and may continue to adversely impact the Company’s business, financial condition, and results of operations, the global economy, and the demand for and prices of oil, natural gas, and NGLs. The unprecedented nature of the current situation makes it impossible for the Company to identify all potential risks related to the pandemic or estimate the ultimate adverse impact that the pandemic may have on its business.
The COVID-19 pandemic and the actions taken by third parties, including, but not limited to, governmental authorities, businesses, and consumers, in response to the pandemic have adversely impacted the global economy and created significant volatility in the global financial markets. Business closures, restrictions on travel, “stay-at-home” or “shelter-in-place” orders, and other restrictions on movement within and among communities have significantly reduced demand for and the prices of oil, natural gas, and NGLs. As of the date of this report, efforts to contain COVID-19 have not been successful in many regions, vaccination programs have encountered delays, and the global pandemic remains ongoing. A continued prolonged period of such reduced demand, the failure to timely distribute or the ineffectiveness of any vaccines, the failure to develop adequate treatments, and other adverse impacts from the pandemic may materially adversely affect the Company’s business, financial condition, cash flows, and results of operations.
The Company’s operations rely on its workforce being able to access its wells, platforms, structures, and facilities located upon or used in connection with its oil and gas leases. Additionally, because the Company has implemented remote working procedures for a significant portion of its workforce for health and safety reasons and/or to comply with applicable national, state, and/or local government requirements, the Company relies on such persons having sufficient access to its information technology systems, including through telecommunication hardware, software, and networks. If a significant portion of the Company’s workforce cannot effectively perform their responsibilities, whether resulting from a lack of physical or virtual access, quarantines, illnesses, governmental actions or restrictions, information technology or telecommunication failures, or other restrictions or adverse impacts resulting from the pandemic, the Company’s business, financial condition, cash flows, and results of operations may be materially adversely affected.
The unprecedented nature of the current situation resulting from the COVID-19 pandemic makes it impossible for the Company to identify all potential risks related to the pandemic or estimate the ultimate adverse impact that the pandemic may have on its business, financial condition, cash flows, or results of operations. Such results will depend on future events, which the Company cannot predict, including the scope, duration, and potential reoccurrence of the COVID-19 pandemic or any other localized epidemic or global pandemic, the distribution and effectiveness of vaccines and treatments, the demand for and the prices of oil, natural gas, and NGLs and the actions taken by third parties, including, but not limited to, governmental authorities, customers, contractors, and suppliers, in response to the COVID-19 pandemic or any other epidemics or pandemics. The COVID-19 pandemic and its unprecedented consequences have amplified, and may continue to amplify, the other risks identified in this report.
Crude oil, natural gas, and NGL priceprices and their volatility could adversely affect ourthe Company’s operating results and the price of our common stock.results.
OurThe Company’s revenues, operating results, and future rate of growth, and carrying value of its oil and gas properties depend highly upon the prices we receiveit receives for ourits sales of crude oil, natural gas, and NGL production.products. Historically, the markets for these commodities have been volatile and are likely to continue to be volatile in the future. For example, the NYMEX daily settlement price for the prompt month oil contract in 20202023 ranged from a high of $63.27$93.67 per barrel to a low of -$36.98$66.61 per barrel. Thebarrel, and the NYMEX daily settlement price for the prompt month natural gas contract in 20202023 ranged from a high of $3.14$3.78 per MMBtu to a low of $1.33$1.74 per MMBtu. The market prices for crude oil, natural gas, and NGLs depend on factors beyond ourthe Company’s control. These factors include demand, which fluctuates with changes in market and economic conditions, and other factors, including:
18


worldwide and domestic supplies and/or inventories of crude oil, natural gas, and NGLs;NGLs and the availability of related pipeline, transportation, import/export, and refining capacity and infrastructure;
actions taken by foreign oil and gas producing nations, including the Organization of the Petroleum Exporting Countries (OPEC) and non-OPEC members that participate in OPEC initiatives (OPEC+);

Our results of operations, as well as the carrying value of our oil and gas properties, are substantially dependent upon the prices of oil, natural gas, and NGLs. Despite slight increases in oil and natural gas prices in 2020,Low prices have remained significantly lower than levels seen in recent years, which haspreviously adversely affected ourand could from time to time in the future adversely affect the Company’s revenues, operating income, cash flow, and proved reserves. Continuedreserves, and a prolonged period of low prices could have a material adverse impact on ourthe Company’s results of operations and cash flows and limit ourits ability to fund capital expenditures. Without the ability to fund capital expenditures, wethe Company would be unable to replace reserves and production. Sustained low prices of crude oil, natural gas, and NGLs maycould also further adversely impact ourthe Company’s business, as follows:
including by weakening ourthe Company’s financial condition and reducing our liquidity;
its liquidity, limiting ourthe Company’s ability to fund planned capital expenditures and operations;
reducingoperations, causing the amount of crude oil, natural gas, and NGLs that we can produce economically;
causing usCompany to delay or postpone some of ourits capital projects;
reducing our revenues, operating income, and cash flows;

reducing the carrying value of our gathering, processing, and transmission facilities, resulting in additional impairments.
OurThe Company’s ability to sell crude oil, natural gas, or NGLs, and/or receive market prices for these commodities, and/or meet volume commitments under transportation services agreements may be adversely affected by pipeline and gathering system capacity constraints, the inability to procure and resell volumes economically, and various transportation interruptions.
A portion of ourthe Company’s crude oil, natural gas, and NGL production in any region may be interrupted, limited, or shut in from time to time for numerous reasons, including as a result of weather conditions, accidents, loss of pipeline or gathering system access, field labor issues or strikes, cyberattacks or terrorist events, or capital constraints that limit the ability of third parties to construct gathering systems, processing facilities, or interstate pipelines to transport our production, or we mightthe Company’s production. Additionally, the Company may voluntarily curtail production in response to market conditions. If a substantial amount of ourthe Company’s production is interrupted or curtailed at the same time, it could temporarily adversely affect ourthe Company’s cash flows. Additionally,Further, if we arethe Company is unable to procure and resell third-party volumes at or above a net price that covers the cost of transportation, ourthe Company’s cash flows could be adversely affected.

Future drilling activities may not be successful, and, if unsuccessful, this failure could have an adverse effect on our future results of operations and financial condition. While all drilling, whether developmental or exploratory, involves these risks,labor. In addition, exploratory drilling involves greater risks of dry holes or failure to find commercial quantities of hydrocarbons. Any such events could have an adverse effect on the Company’s future results of operations and financial condition. Exploration costs and dry hole expenses incurred by the Company during the reporting period are further discussed in this Annual Report on Form 10-K and reflected in the consolidated financial statements included herein.
OurThe Company’s commodity price risk management and trading activities may prevent usit from benefiting fully from price increases and may expose usit to other risks.
To the extent that we engagethe Company engages in price risk management activities to protect ourselvesitself from commodity price declines, wethe Company may be prevented from realizing the benefits of price increases above the levels of the derivative instruments used to manage price risk. In addition, ourincreases. The Company’s hedging arrangements may expose usit to the risk of financial loss, in certain circumstances, including instances in which:

Global pandemics have previously, may continue to, and may in the future adversely impact the Company’s business, financial condition, and results of operations; the global economy; the demand for and prices of oil, natural gas, and NGLs; and the performance of the Company’s workforce.
Global pandemics and the actions taken by third parties, including, but not limited to, governmental authorities, businesses, and consumers, in response to such pandemics, including the COVID-19 pandemic, have previously adversely impacted and may from time to time in the future adversely impact the global economy, resulting in significant volatility in the global financial markets, and the demand for, and the prices of, oil, natural gas, and NGLs, which may materially adversely affect the Company’s business, financial condition, cash flows, and results of operations. Additionally, the Company’s operations rely on its workforce having access to its wells, platforms, structures, offices, and facilities. If a significant portion of the Company’s workforce cannot effectively perform their responsibilities, whether resulting from a lack of physical or virtual access, quarantines, illnesses, governmental actions or restrictions (including vaccine mandates and the reactions thereto), or other restrictions or adverse impacts resulting from a pandemic, the Company’s business, financial condition, cash flows, and results of operations may be materially adversely affected.
RISKS RELATED TO OPERATIONS AND DEVELOPMENT PROJECTS
OurThe Company’s operations involve a high degree of operational risk, particularly risk of personal injury, damage to or loss of equipment,property, and environmental accidents.
OurThe Company’s operations are subject to hazards and risks inherent in the drilling, production, and transportation of crude oil, natural gas, and NGLs, including:
including well blowouts, explosions, and cratering;
fires, cratering, pipeline or other facility ruptures and spills;
fires;
formations with abnormal pressures;
equipment malfunctions;
hurricanes, storms, and/or cyclones, which could affect our operations inspills, adverse weather conditions, including those impacting the Company’s offshore operating areas, such as on and offshore the Gulf Coast, North Sea, and Suriname, and other natural and anthropogenic disasters and weather conditions; and
surface spillage and surface or ground water contamination from petroleum constituents, saltwater, or hydraulic fracturing chemical additives.
2014


Failureground water contamination, and failure or loss of equipment, as the resultequipment. These events, including ineffective containment of equipment malfunctions, cyberattacks, or natural disasters such as hurricanes,events, could result in property damages, personal injury, environmental pollution, and other damages for which wethe Company could be liable. Litigation arising from a catastrophic occurrence, such as a well blowout, explosion, fire at a location where our equipment and services are used, or ground water contamination from hydraulic fracturing chemical additives may result in substantial claims for damages. Ineffective containment of a drilling well blowout or pipeline rupture or surface spillage and surface or ground water contamination from petroleum constituents or hydraulic fracturing chemical additives could result in extensive environmental pollution and substantial remediation expenses. If a significant amount of ourthe Company’s production is interrupted, our containment efforts prove to be ineffective, or litigation arises as the result of a catastrophic occurrence, ourthe Company’s cash flows and, in turn, ourits results of operations could be materially and adversely affected.
Weather and climate may have a significant adverse impact on ourthe Company’s revenues and production.
Demand for oil and natural gas are, to a significant degree, dependent on weather and climate, which impact the price we receivethe Company receives for the commodities we produce.it produces. In addition, ourthe Company’s exploration, development, and developmentproduction activities and equipment have been and can be adversely affected by severe weather, such as freezing temperatures, hurricanes in the Gulf of Mexico, or major storms in the North Sea, each of which have previously caused and may cause a loss of production from temporary cessation of activity or lost or damaged equipment. OurThe Company’s planning for normal climatic variation, insurance programs, and emergency recovery plans may inadequately mitigate the effects of such weather conditions, and not all such effects can be predicted, eliminated, or insured against.
OurThe Company’s insurance policies do not cover all of the risks we face,the Company faces, which could result in significant financial exposure.
Exploration for and production of crude oil, natural gas, and NGLs can be hazardous, involving natural disasters and other events such as blowouts, cratering, fires, explosions, and loss of well control,involves hazards, which can result in damage to or destruction of wells or production facilities, injury to persons, loss of life, or damage to property or the environment. OurThe Company’s international operations are also subject to political risk.and economic risks. The insurance coverage that we maintainthe Company maintains against certain losses or liabilities arising from ourits operations may be inadequate to cover any such resulting liability; moreover, insurance is not available to usthe Company against all operational risks.
A terrorist or cyberattack targeting systems and infrastructure used by us or others in the oil and gas industry may adversely impact our operations.
Our business has become increasingly dependent on digital technologies to conduct certain exploration, development, and production activities. We depend on digital technology to estimate quantities of oil and gas reserves, process and record financial and operating data, analyze seismic and drilling information, communicate with our employees and third-party partners, and conduct many of our activities. Unauthorized access to our digital technology could lead to operational disruption, data corruption, communication interruption, loss of intellectual property, loss of confidential and fiduciary data, and loss or corruption of reserves or other proprietary information. Also, external digital technologies control nearly all of the oil and gas distribution and refining systems in the United States and abroad, which are necessary to transport and market our production. A cyberattack directed at oil and gas distribution systems could damage critical distribution and storage assets or the environment, delay or prevent delivery of production to markets, and make it difficult or impossible to accurately account for production and settle transactions. Any such terrorist attack, environmental activist group activity, or cyberattack that affects the Company or our customers, suppliers, or others with whom we do business could have a material adverse effect on our business, cause us to incur a material financial loss, subject us to possible legal claims and liability, and/or damage our reputation.
While certain of ourthe Company’s insurance policies may allowprovide coverage for coverage of associated damages resulting from such events, if wethe Company were to incur a significant liability for which we wereit was not fully insured, then it could have a material adverse effect on ourthe Company’s financial position, results of operations, and cash flows. In addition, if such an event were to occur, then the proceeds of any such insurance may not be paid in a timely manner or may not be sufficient to cover all of the Company’s losses.
A cyberattack targeting systems and infrastructure used by the Company or others in the oil and gas industry may adversely impact the Company’s operations.
There are numerous and evolving risks to the Company’s data, technology, and information systems from cyber threat actors, including criminal hackers, state-sponsored intrusions, industrial espionage, and employee malfeasance. The Company’s operations are dependent on digital technologies, including to estimate reserves, process financial and operating data, analyze drilling information, and communicate with personnel. Unauthorized access to the Company’s data, technology, and information systems could lead to operational disruption, communication interruption, disruption in access to financial reporting systems, loss, misuse, or corruption of data and proprietary information. In addition, unauthorized access to third party information systems could interrupt the oil and gas distribution and refining systems in the U.S. and abroad, which are necessary to transport and market the Company’s production. Cyberattacks directed at oil and gas distribution systems have previously and could again in the future damage critical distribution and storage assets or the environment. The potential impacts of a cyber incident could be made worse by a delay or failure to detect the occurrence, continuance, or extent of such an incident.
The Company expends significant resources to protect its digital systems and data, whether such data is housed internally or externally by third parties, against cyberattacks and may be insufficient if such an event wererequired to occur.
expend further resources as cyber threat actors become more sophisticated and as regulations related to cyberattacks become more complex. Cyberattacks, including malicious software, data privacy breaches by employees, insiders, or others with authorized access to the Company’s systems, cyber or phishing attacks, ransomware attacks, supply chain vulnerabilities, business email compromises, other attempts to gain unauthorized access to the Company’s data and systems, and other electronic security breaches could have a material adverse effect on the Company’s business, cause it to incur a material financial loss, subject it to possible legal claims and liability, and/or damage its reputation. While we have experienced cyberattacks in the past, we haveCompany has not suffered any material losses as a result of such attacks; however,cyberattacks, there is no assurance that wethe Company will not suffer such losses in the future. Further, as cyberattacks continue to evolve, we may be required to expend significant additional resources to continue to modify or enhance our protective measures or to investigate and remediate any vulnerabilities to cyberattacks. In addition, cyberattacks against us or others in our industry could result in additional regulations, which could lead to increased regulatory compliance costs, insurance coverage cost, or capital expenditures. The Company cannot predict the potential impact that such additional regulations could have on our business and operations or the energy industry at large.

Material differences between the estimated and actual timing of critical events or costs may affect the completion and commencement of production from development projects.
We areThe Company is involved in several large development projects, and the completion of these projects may be delayed beyond ourthe Company’s anticipated completion dates. OurThese projects may be delayed by project approvals from joint venture
15


partners, timely issuances of permits and licenses by governmental agencies, weather conditions, manufacturing and delivery schedules of critical equipment, and other unforeseen events. Delays and differences between estimated and actual timing of critical events and development costs (including for equipment and personnel) may adversely affect ourthe Company’s large development projects (including forcing the Company to abandon such projects) and ourits ability to participate in large-scale development projects in the future. In addition, our estimates of future development costs are based on our current expectations of prices and other costs of equipment and personnel we will need to implement such projects. Our actual future development costs may be significantly higher than we currently estimate. If costs become too high, our development projects may become uneconomic to us, and we may be forced to abandon such development projects.
RISKS RELATED TO RESERVES AND LEASEHOLD ACREAGE
Discoveries or acquisitions of additional reserves are needed to avoid a material decline in reserves and production.
The production rate from oil and natural gas properties generally declines as reserves are depleted, while related per-unit production costs generally increase as a result of decreasing reservoir pressures and other factors. Therefore, unless we addfuture oil and gas production is highly dependent upon the Company’s level of success in adding reserves through exploration and development activities, identifyidentifying additional behind-pipe zones, secondary recovery reserves, or tertiary recovery reserves through engineering studies, or acquireacquiring additional properties containing proved reserves, our estimated proved reserves will decline materially as reserves are produced. Futurereserves. As oil and gas production is, therefore, highly dependent upon our level of success in acquiring or finding additional reserves on an economic basis. Furthermore, if oil ornatural gas prices increase, ourthe Company’s cost for additional reserves could also increase.
WeThe Company may fail to fully identify potential problems related to acquired reserves or to properly estimate those reserves.
Although we performthe Company performs a review of properties that we acquire that we believeit acquires, which the Company believes is consistent with industry practices, such reviews are inherently incomplete. It generally is not feasible to review in-depth every individual property involved in each acquisition. Ordinarily, we will focus our review efforts on the higher-value properties and will sample the remainder. However, even a detailed review of records and properties may not necessarily reveal existing or potential problems, nor will it permit us as a buyer to become sufficiently familiar with the properties to assess fully and accurately their deficiencies and potential. Inspections may not always be performed on every well,incomplete, and environmental problems, such as groundwater contamination, are not necessarily observable even when an inspection is undertaken. Even when problems are identified, we often assume certain environmental and other risks and liabilities in connection with acquired properties. There are numerous uncertainties inherent in estimating quantities of proved oil and gas reserves and future production rates and costs with respect to acquired properties, and actual results may vary substantially from those assumed in the estimates. In addition, thereThere can be no assurance that acquisitions will not have an adverse effect upon ouradversely impact the Company’s operating results, particularly during their integration into the periods in which the operations of acquired businesses are being integrated into ourCompany’s ongoing operations.
Crude oil, natural gas, and NGL reserves are estimates, and actual recoveries may vary significantly.
There are numerous uncertainties inherent in the process of estimating crude oil, natural gas, and NGL reserves and their value. Reservoir engineeringvalue, which is ahighly subjective process of estimating underground accumulations of crude oil, natural gas, and NGLs that cannot be measured in an exact manner. Because of the high degree of judgment involved, the accuracy of any reserve estimate is inherently imprecise and a function ofrelies on the quality of available data and the accuracy of engineering and geological interpretation. OurThe Company’s reserves estimates are based on 12-month average prices, except where contractual arrangements exist; therefore,exist, causing reserves quantities willto change when actual prices increase or decrease. In addition, results of drilling, testing, and production may substantially change the reserve estimates for a given reservoir over time. The estimates of ourthe Company’s proved reserves and estimated future net revenues also depend on a number of factors and assumptions that may vary considerably from actual results, including:
including historical production from the area compared with production from other areas;
areas, the results of drilling, testing, and production for a reservoir over time, the use of volumetric analysis versus production history, the effects of regulations by governmental agencies, including changes to severance and excise taxes;
in laws (including taxes), future operating, workover, and remediation costs, and capital expenditures; and
workover and remediation costs.
22


For these reasons, estimates of the economically recoverable quantities of crude oil, natural gas, and NGLs attributable to any particular group of properties, classifications of those reserves, and estimates of the future net cash flows expected from them prepared by different engineers or by the same engineers but at different times may vary substantially.expenditures. Accordingly, reserves estimates may be subject to upward or downward adjustment, and actual production, revenue, and expenditures with respect to ourthe Company’s reserves likely will vary, possibly materially, from estimates.
Additionally, because some of our reserves estimates are calculated using volumetric analysis, those estimates are less reliable than the estimates based on a lengthy production history. Volumetric analysis involves estimating the volume of a reservoir based on the net feet of pay of the structure and an estimation of the area covered by the structure. In addition, realization or recognition of proved undeveloped reserves will depend on ourthe Company’s development schedule and plans. A change in future development plans for proved undeveloped reserves could cause the discontinuation of the classification of these reserves as proved.
Certain of ourthe Company’s undeveloped leasehold acreage is subject to leases that will expire over the next several years unless production is established on units containing the acreage.
A sizeable portion of ourthe Company’s acreage is currently undeveloped. Unless production in paying quantities is established on units containing certain of these leases during their terms, the leases will expire. If ourthe leases expire, wethe Company will lose ourits right to develop the related properties. OurThe Company’s drilling plans for these areas are subject to change based upon various factors, including drilling results, commodity prices, the availability and cost of capital, drilling and production costs, availability of drilling services and equipment, gathering system and pipeline transportation constraints, and regulatory approvals.
RISKS RELATED TO COUNTERPARTIES
The credit risk of financial institutions could adversely affect us.the Company and result in a significant loss.
We areThe Company is party to numerous transactions with counterparties in the financial services industry, including commercial banks, investment banks, insurance companies, other investment funds, and other institutions. These transactions expose us to credit risk in the event of default of our counterparty. Deterioration in the credit or financial markets may impact the credit ratings of our current and potential counterparties and affect their ability to fulfill their existing obligations to us and their willingness to enter into future transactions with us. We may also have exposure to financial institutions, including in the form of derivative transactions in connection with any hedges. We also have exposurehedges and claims under the Company’s insurance policies, which expose the

Deterioration or volatility in the credit or financial markets, changes in commodity prices, and changes in a counterparty’s liquidity may affect the counterparties’ ability to fulfill their existing obligations to the Company. In addition, if any lender under ourthe Company’s credit facilities is unable to fund its commitment, ourthe Company’s liquidity willmay be reduced by an amount up to the aggregate amount of such lender’s commitment under our credit facilities.
We are exposed to a risk of financial loss if a counterparty fails to perform under a derivative contract. This risk of counterparty non-performance is of particular concern given the recent volatility of the financial markets and significant decline in commodity prices, which could lead to sudden changes in a counterparty’s liquidity and impair its ability to perform under the terms of the derivative contract. We are unable to predict sudden changes in a counterparty’s creditworthiness or ability to perform. Even if we do accurately predict sudden changes, our ability to negate the risk may be limited depending upon market conditions.thereunder. Furthermore, the bankruptcy of one or more of our hedge providersthe Company’s counterparties or some other similar proceeding or liquidity constraint might make it unlikely that wethe Company would be able to collect all or a significant portion of amounts owed to usit by the distressed entity or entities. During periods of falling commodity prices, our hedge receivable positions increase, which increases our exposure. Ifentities, and the creditworthiness of our counterparties deteriorates and results in their nonperformance, weCompany could incur a significant loss.

Concerns about global economic conditions and the volatility of oil, natural gas, and NGL prices have had a significant adverse impact on the oil and gas industry. We areThe Company is exposed to risk of financial loss from trade, joint venture, joint interest billing, and other receivables. We sell our crude oil, natural gas, and NGLs to a variety of purchasers. As operator, we pay expenses and bill our non-operating partners for their respective shares of costs.

Our liabilitiespreviously owned assets, could be adversely affected in the event one or more of ourits transaction counterparties are financially distressed or become the subject of a bankruptcy case.
From time to time we have divested noncore or nonstrategic domestic and international assets. The agreements relating to these transactionsthe Company’s divestment of domestic and international assets generally contain provisions pursuant to which liabilities related to past and future operations have been(one of the most significant of which is the decommissioning of wells and facilities) are allocated between the parties by means of liability assumptions, indemnities, escrows, trusts, bonds, letters of credit, and similar arrangements. One of the most significant of these liabilities involves the decommissioning of wells and facilities previously owned by us. One or more of the counterparties in these transactions could fail to perform its obligations under these agreements as a result of financial distress. In the event that any such counterparty were to become the subject of a casedistress or proceeding under Title 11 of the United States Code or any other relevant insolvency law or similar law (which we collectively refer to as Insolvency Laws), the counterparty may not perform its obligations under the agreements related to these transactions.

On November 30, 2020, the ICE Benchmark Administration (IBA) announced that it intends to continue publishing LIBOR until the end of June 2023, beyond the previously announced 2021 cessation date. The IBA announcement was supported by announcements from the United Kingdom’s Financial Conduct Authority (FCA), which regulates LIBOR,investment advisers, public pension funds, universities, and the Board of Governorsother members of the Federal Reserve System, Federal Deposit Insurance Corporation and Office of the Comptroller of the Currency (U.S. Regulators).

These announcements indicate that the continuation of LIBOR on the current basis may not be assured after 2021 and will not be assured beyond 2023. In light of these recent announcements, the future of LIBOR at this time is uncertain, and any changescampaign efforts have resulted in the methods by which LIBOR is determined or regulatory activity related to LIBOR’s phaseout could cause LIBOR to perform differently thandivestment of investments in the pastoil and gas industry and increased pressure on lenders and other financial services companies to limit or cease to exist.
In the United States, the Alternative Reference Rates Committee (the working group formed to recommend an alternative rate to LIBOR) has identified the Secured Overnight Financing Rate (SOFR) as its preferred alternative rate for LIBOR. There can be no guarantee that SOFR will become a widely-accepted benchmark in place of LIBOR. Although the full impact of the transitioncurtail activities with oil and gas companies. If investors or financial institutions shift funding away from LIBOR, including the discontinuance of LIBOR publication and the adoption of SOFR as the replacement rate for LIBOR, remains unclear, these changes may have an adverse impact on our floating rate indebtedness and financing costs under our revolving credit facility.
Our ability to declare and pay dividends is subject to limitations.
The payment of future dividends on our capital stock is subject to the discretion of our board of directors, which considers, among other factors, our operating results, overall financial condition, credit-risk considerations, and capital requirements, as well as general business and market conditions.

RISKS RELATED TO FINANCIAL RESULTS
Future economic conditions in the U.S. and certain international markets may materially adversely impact our operating results.
Current global market conditions and uncertainty, including the economic instability in Europe and certain emerging markets, are likely to have significant long-term effects on our operating results. Global economic growth drives demand for energy from all sources, including fossil fuels. A lower future economic growth rate could result in decreased demand growth for our oil and gas production as well as lower commodity prices, which would reduce our cash flows from operations and our profitability.
We faceThe Company faces strong industry competition that may have a significant negative impact on ourthe Company’s results of operations.
Strong competition exists in all sectors of the oil and gas E&P industry. We compete with major integrated and other independent oil and gas companiesThe Company competes for acquisitions of oil and gas leases, properties, and reserves, equipment, and labor, required to explore, develop, and operate those properties,key personnel, and marketing of crude oil, natural gas, and NGL production. Crude oil, natural gas, and NGLproduction, the prices of which impact the costs of properties available for acquisition and the number of companies with the financial resources available to pursue acquisition opportunities. Many of our competitors have financial and other resources substantially larger than we possess and have established strategic, long-term positions and maintain strong governmental relationships in countries in which we may seek new entry. As a consequence, we may be at a competitive disadvantage in bidding for drilling rights. In addition, many of our larger competitors may have a competitive advantage when responding to factors that affect demand for oil and gas production, such as fluctuating worldwide commodity prices and levels of production, the cost and availability of alternative fuels, and the application of government regulations. We also compete in attracting and retaining personnel, including geologists, geophysicists, engineers, and other specialists.acquisitions. These competitive pressures may have a significant negative impact on ourthe Company’s results of operations.
The Company’s ability to utilize net operating losses and other tax attributes to reduce future taxable income may be limited if the Company experiences an ownership change.
As described in Note 10—11—Income Taxes of the Notes to Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K, the Company has substantial net operating loss carryforwards (NOLs) and other tax attributes available to potentially offset future taxable income. If the Company were to experience an “ownership change” under Section 382 of the Internal Revenue Code of 1986, as amended, which is generally defined as a greater than 50 percentage point change, by value, in the Company’s equity ownership by five-percent shareholders over a three-year period, the Company’s ability to utilize its pre-change NOLs and other pre-change tax attributes to potentially offset its post-change income or taxes may be limited. Such a limitation could materially adversely affect the Company’s operating results or cash flows by effectively increasing its future tax obligations.flows.
RISKS RELATED TO GOVERNMENTAL REGULATION AND POLITICAL RISKS
WeThe Company may incur significant costs related to environmental matters.
As an owner or lessee and operator of oil and gas properties, we arethe Company is subject to various federal, state, local, and foreign country laws and regulations relating to the discharge of materials into and protection of the environment. These laws and regulations may, among other things, impose liability on the lessee under an oil and gas lease for the cost of pollution cleanup and other remediation activities resulting from operations, subject the lessee to liability for pollution and other damages, limit or

constrain operations in affected areas, require significant capital expenditures to comply with increasingly strict environmental laws and regulations, and require suspension or cessation of operations in affected areas. OurThe Company’s efforts to limit ourits exposure to such liability and cost may prove inadequate and result in significant adverse effects to ourthe Company’s results of operations. In addition, it is possible that the increasingly strict requirements imposed by environmental lawsoperations and enforcement policies could require us to make significant capital expenditures. Such capital expenditures could adversely impact our cash flows and our financial condition.flows.

Our United StatesThe Company’s U.S. operations are subject to governmental risks.
Our United StatesThe Company’s U.S. operations have been, and at times in the future may be, affected by political developments and by federal, state, and local laws and regulations, such asincluding restrictions on production, changes in taxes royalties and other amounts payable to governments, or governmental agencies, price or gathering rate controls, and environmental protection laws and regulations.
In response to the Deepwater Horizon incident in the U.S. Gulf of Mexico in April 2010regulations, and as directed by the Secretary of the U.S. Department of the Interior, the Bureau of Ocean Energy Management (BOEM) and the Bureau of Safety and Environmental Enforcement (BSEE) issued guidelines and regulations regarding safety, environmental matters, drilling equipment,security for plugging, abandonment, and decommissioning applicable to drillingobligations, including in the Gulf of Mexico. These regulations imposed additional requirements and caused delays with respect to development and production activities in the Gulf of Mexico.
With respect to oil and gas operations in the Gulf of Mexico, the BOEM issued a Notice to Lessees (NTL No. 2016-N01) significantly revising the obligations of companies operating in the Gulf of Mexico to provide supplemental assurances of performance with respect to plugging, abandonment, and decommissioning obligations associated with wells, platforms, structures, and facilities located upon or used in connection with such companies’ oil and gas leases. While the NTL was paused in mid-2017 and is currently listed on BOEM’s website as “rescinded,” if reinstated, the NTL will likely require that Apache provide additional security to BOEM with respect to plugging, abandonment, and decommissioning obligations relating to Apache’s current ownership interests in various Gulf of Mexico leases. We are working closely with BOEM to make arrangements for the provision of such additional required security, if such security becomes necessary under the NTL. Additionally, we are not able to predict the effect that these changes might have on counterparties to which Apache has sold Gulf of Mexico assets or with whom Apache has joint ownership. Such changes could cause the bonding obligations of such parties to increase substantially, thereby causing a significant impact on the counterparties’ solvency and ability to continue as a going concern.
New political developments, the enactment of new or stricter laws or regulations or other governmental actions impacting our United Statesthe Company’s U.S. operations, and increased liability for companies operating in this sectorthe oil and gas E&P industry may adversely impact ourthe Company’s results of operations.
ChangesProposed federal, state, or local regulation regarding hydraulic fracturing could increase the Company’s operating and capital costs.
The Company routinely uses fracturing techniques in the U.S. and other regions to existingexpand the available space for oil and natural gas to migrate toward the wellbore, typically at substantial depths in formations with low permeability. Governmental entities have previously taken actions to regulate, and several proposals are before the U.S. Congress that, if implemented, would further regulate, hydraulic fracturing. If adopted, such regulations relatedcould impose more stringent permitting, reporting, and well construction requirements or otherwise seek to emissionsban fracturing activities. These activities and the impact of any changes in climate could adversely impact our business.

Any new federal, state, or assess some form of greenhouse gas (GHG) related feeslocal restrictions on our operations. Exposure has not been material to date, although a change in existing regulations could adversely affect our cash flows and results of operations. Additionally, there has been discussion in other countries where we operate, including the United States, regarding legislation or regulation of GHG. Any such legislation or regulation, if enacted, could either tax or assess some form of GHG-related fees on our operations and could lead to increased operating expenses or cause us to make significant capital investments for infrastructure modifications.
In the event the predictions for rising temperatures and sea levels suggested by reports of the United Nations Intergovernmental Panel on Climate Change do transpire, we do not believe those events by themselves are likely to impact our assets or operations. However, any increase in severe weather could have a material adverse effect on our assets and operations.
Negative public perception regarding us and/or our industry could have an adverse effect on our operations.
Negative public perception regarding us and/or our industry resulting from, among other things, concerns raised by advocacy groups about hydraulic fracturing waste disposal, oil spills, and explosions of natural gas transmission lines may lead tocould result in increased regulatory scrutiny, which may, in turn, lead to new state and federal safety and environmental laws, regulations, guidelines, and enforcement interpretations. These actions may cause operational delayscompliance costs or additional restrictions increased operating costs, additional regulatory burdens, and increased risk of litigation. Moreover, governmental authorities exercise considerable discretion inon the timing and scope of permit issuance, and the public may engage in the permitting process, including through intervention in the courts. Negative public perception could cause the permits we require to conduct our operations to be withheld, delayed, or burdened by requirements that restrict our ability to profitably conduct our business.

Company’s U.S. operations.
Changes in tax rules and regulations, or interpretations thereof, may adversely affect ourthe Company’s business, financial condition, and results of operations.
On December 22, 2017, the Tax CutsFederal, state, and Jobs Act (the TCJA) was signed into law. In addition to reducing the U.S. corporate income tax rate from 35 percent to 21 percent effective January 1, 2018, certain provisions in the TCJA move the U.S. away from a worldwide tax system and closer to a territorial system for earnings of foreign corporations, establishing a participation exemption system for taxation of foreign income. The new law includes a transition rule to effect this participation exemption regime. The TCJA also includes provisions which could impact or limit the Company’s ability to deduct interest expense or utilize net operating losses.
The U.S. federal and state income tax laws affecting oil and gas exploration, development, and extraction may be further modified by administrative, legislative, or judicial interpretation at any time. For example, the U.K. enacted the Energy Profits Levy, which assesses an additional levy of 35 percent, effective for the period of January 1, 2023, through March 31, 2028, on the profits of oil and gas companies operating in the U.K. and the U.K. Continental Shelf. Additionally, in the U.S., the Inflation Reduction Act of 2022 introduced a new 15 percent corporate alternative minimum tax (Corporate AMT) for taxable years beginning after December 31, 2022, on applicable corporations with an average annual adjusted financial statement income (AFSI) that exceeds $1.0 billion for any three consecutive tax years preceding the tax year at issue. Effective January 1, 2024, the Company is subject to the Corporate AMT. Accordingly, any resulting Corporate AMT liability could adversely affect the Company’s future financial results, including earnings and cash flows.
Previous legislative proposals, if enacted into law, could make significant changes to suchtax laws, including the elimination of certain key U.S. federal income tax incentives currently available to oil and gas exploration and productionE&P companies. These changes include, but are not limited to, (i) the repeal of the percentage depletion allowance for oil and gas properties, (ii) the elimination of current deductions for intangible drilling and development costs, and (iii) an extension of the amortization period for certain geological and geophysical expenditures. The passage or adoption of these changes, or similar changes, could eliminate or postpone certain tax deductions that are currently available with respect to oil and gas exploration and development. We areThe Company is unable to predict whether any of these changes or other proposals will be enacted. Any such changes could adversely affect ourthe Company’s business, financial condition, and results of operations.
Proposed federal, state,RISKS RELATED TO CLIMATE CHANGE
The impacts of energy transition could adversely affect the Company’s business, operating results, and financial condition.
In recent years, increasing attention has been given to corporate activities related to climate change and energy transition. This focus, together with shifting preferences and attitudes with respect to the generation and consumption of energy, the use of hydrocarbons, and the use of products manufactured with, or localpowered by, hydrocarbons, may result in increased availability of, and demand for, energy sources other than oil and natural gas, including wind, solar, and hydroelectric power, and the
19


development of, and increased demand from consumers and industries for, lower-emission products and services, including electric vehicles and renewable residential and commercial power supplies, as well as more energy-efficient products and services.
These developments could adversely impact the demand for products powered by or manufactured with hydrocarbons and the demand for, and in turn the prices the Company receives for, its crude oil, natural gas, and NGL products, which could materially and adversely affect the Company’s business and financial performance.
Changes to existing regulations related to emissions and the impact of any changes in climate could adversely impact the Company’s business.
Certain countries where the Company operates, including the U.K., either tax or assess some form of greenhouse gas (GHG) related fees on the Company’s operations. Exposure has not been material to date, although a change in existing regulations could adversely affect the Company’s cash flows and results of operations. Additionally, there has been discussion in other countries where the Company operates, including the U.S., regarding changes in legislation or heightened regulation regarding hydraulic fracturing could increase our operatingof GHGs, including to monitor and capital costs.limit existing emissions of GHGs and to restrict or eliminate future emissions. Moreover, in January 2024, the EPA announced a proposed rule to assess a charge on certain methane emissions in the oil and gas industry. The Company is currently evaluating the proposed rule and its applicability to the Company.
Several proposals are before the U.S. Congress that, if implemented, would either prohibit or restrict the practice of hydraulic fracturing or subject the process to regulation under the Safe Drinking Water Act. SeveralAdditionally, various states and political subdivisions are considering legislation, ballot initiatives, executive orders, or other actions to regulate hydraulic fracturing practices that could impose more stringent permitting, transparency, and well construction requirements on hydraulic-fracturing operations or otherwise seek to ban fracturing activities altogether. Hydraulic fracturinggroups of wells and subsurface water disposal are also under public and governmental scrutiny due to potential environmental and physical impacts, including possible contamination of groundwater and drinking water and possible links to induced seismicity. In addition, some municipalitiesstates have significantly limited or prohibited drilling activities and/or hydraulic fracturingadopted or are considering doing so. We routinely useadopting legislation, regulations, or other regulatory initiatives that are focused on such areas as GHG cap-and-trade programs, carbon taxes, reporting and tracking programs, restriction of emissions, electric vehicle mandates, and combustion engine phaseouts.
Any such legislation, regulations, or other regulatory initiatives, if enacted, or additional or increased taxes, assessments, or GHG-related fees on the Company’s operations could lead to increased operating expenses or cause the Company to make significant capital investments for infrastructure modifications.
Enhanced focus on ESG matters could have an adverse effect on the Company’s operations.
Enhanced focus on ESG matters related to, among other things, concerns raised by advocacy groups about climate change, hydraulic fracturing, techniqueswaste disposal, oil spills, and explosions of natural gas transmission pipelines may lead to increased regulatory review, which may, in turn, lead to new state and federal safety and environmental laws, regulations, guidelines, and enforcement interpretations. These actions may cause operational delays or restrictions, increased operating costs, additional regulatory burdens, increased risk of litigation, and adverse impacts on the Company’s access to capital. Moreover, governmental authorities exercise considerable discretion in the U.S.timing and other regionsscope of permit issuance and regulatory approvals. Negative public perception could cause the permits or regulatory approvals the Company requires to expandbe withheld, delayed, or burdened by requirements that restrict the available space for natural gasCompany’s ability to profitably conduct its business.
The Company’s estimates used in various scenario planning analyses could differ materially from actual results and oilcould expose the Company to migrate towardnew or additional risks.
Given the wellbore. It is typically done at substantial depths in formations with low permeability.
Although it is not possible at this time to predict the final outcomedynamic nature of the governmental actions regarding hydraulic fracturing, any new federal, state,Company’s business, the Company generally performs annual scenario analyses with five-year time horizons. When analyzing longer-term scenarios, the Company relies on external analysis for demand scenarios, carbon pricing, and comparison-pricing scenarios, which are then compared to the Company’s internally prepared base-case pricing analysis averaged out to the year 2040. Given the numerous estimates that are required to run these scenarios, the Company’s estimates could differ materially from actual results. The Company publicly discloses these metrics and its related assumptions and analysis in its annual sustainability report. By electing to disclose these metrics, the Company may face increased scrutiny related to its ESG initiatives. Any harm to the Company’s reputation resulting from publicly disclosing such these metrics, expanding disclosures related to such metrics, or local restrictionsfailing to achieve such metrics or abiding by such disclosures could adversely affect the Company’s business, financial performance, and growth.
The guidance upon which the Company’s consumptive water use reporting was modified and could be revised in the future, resulting in the over or underreporting of the Company’s consumptive water use.
In 2022, the Company modified the way it reports its water data compared to previous years and restated its data from prior years. Previously, the Company included produced water usage in its consumptive use calculations, which led to an over-reporting of consumptive water use. Based on hydraulic fracturingre-evaluation of water reporting definitions and guidance, the Company determined that mayproduced water (non-potable water released from deep underground formations and brought to the surface during oil and gas exploration and production) should not be imposedclassified as consumed in areasthe same sense as fresh water. The

Company’s revised reporting now reflects only fresh water and non-potable water from surface water or shallow groundwater that are consumed in which we conduct businessoil and gas operations.
The treatment and disposal of produced water is becoming more highly regulated and restricted and could result in increased complianceexpose the Company to additional costs or additionallimit certain operations.
The treatment and disposal of produced water is becoming more highly regulated and restricted. Regulators in some states, such as the Railroad Commission of Texas, have taken actions to limit disposal well activities (including orders to temporarily shut down or to curtail water injection) and to require the monitoring of seismic activity. While the Company remains focused on reusing or recycling water over disposal of water, the Company’s costs for obtaining and disposing of water could increase significantly if reusing and recycling water becomes impractical. Further, compliance with reporting and environmental regulations governing the withdrawal, storage, use, and discharge of water and restrictions related to disposal wells may increase the Company’s operating restrictions incosts or capital expenses or cause the U.S.Company to limit production, which could materially and adversely affect its business, results of operations, and financial conditions.
RISKS RELATED TO INTERNATIONAL OPERATIONS
International operations have uncertain political, economic, and other risks.
OurThe Company’s operations outside the United StatesU.S. are based primarily in Egypt and the United Kingdom.U.K. On a barrel equivalent basis, approximately 4249 percent of our 2020the Company’s 2023 production was outside the United States,U.S., and approximately 3331 percent of ourthe Company’s estimated proved oil and gas reserves as of December 31, 2020,2023, were located outside the United States.U.S. As a result, a significant portion of ourthe Company’s production and resources are subject to the increased political and economic risks and other factors associated with international operations, including, but not limited to:
generalto strikes and civil unrest;
the risk of war, acts of terrorism, expropriation and resource nationalization, and forced renegotiation or modification of existing contracts, including through prospective or retroactive changes in the laws and regulations applicable to such contracts;
import and export regulations;
taxation policies including royalty and tax increases and retroactive tax claims, and investment restrictions;
price control;
transportation regulations and tariffs;
constrained oil or natural gas markets dependent on demand in a single or limited geographical area;

controls; exchange controls, currency fluctuations, devaluations, or other activities that limit or disrupt markets and restrict payments or the movement of funds;
constrained oil or natural gas markets dependent on demand in a single or limited geographical area; laws and policies of the United StatesU.S. affecting foreign trade, including trade sanctions;
the effects of the U.K.’s withdrawal from the European Union, including any resulting instability in global financial markets or the value of foreign currencies such as the British pound;
the possibility of being subject to exclusive jurisdiction of foreign courts in connection with legal disputes relating to licenses to operate and concession rights in countries where wethe Company currently operate;
operates; the possible inability to subject foreign persons, especially foreign oil ministries and national oil companies, to the jurisdiction of courts in the United States;U.S.; and
difficulties in enforcing ourthe Company’s rights against a governmental agency because of the doctrine of sovereign immunity and foreign sovereignty over international operations.
Foreign countries have occasionally asserted rights to oil and gas properties through border disputes. If a country claims superior rights to oil and gas leases or concessions granted to usthe Company by another country, ourthe Company’s interests could decrease in value or be lost. Even ourthe Company’s smaller international assets may affect ourits overall business and results of operations by distracting management’s attention from ourits more significant assets. Certain regions of the world in which we operatethe Company operates have a history of political and economic instability. This instability could result in new governments or the adoption of new policies that might result in a substantially more hostile attitude toward foreign investments such as ours.the Company’s. In an extreme case, such a change could result in termination of contract rights and expropriation of ourthe Company’s assets. This could adversely affect ourthe Company’s interests and ourits future profitability.
The impact that future terrorist attacks or regional hostilities, as have occurred in countries and regions in which we operate,the Company operates, may have on the oil and gas industry in general and on ourthe Company’s operations in particular is not known at this time. Uncertainty surrounding military strikes or a sustained military campaign may affect operations in unpredictable ways, including disruptions of fuel supplies and markets, particularly oil, and the possibility that infrastructure facilities, including pipelines, production facilities, processing plants, and refineries, could be direct targets or indirect casualties of an act of terror or war. WeThe Company may be required to incur significant costs in the future to safeguard ourits assets against terrorist activities.
A further deterioration of conditions in Egypt or changes in the economic and political environment in Egypt could have an adverse impact on ourthe Company’s business.
DeteriorationFurther deterioration in the political, economic, and social conditions or other relevant policies of the Egyptian government, such as changes in laws or regulations, export restrictions, expropriation of ourthe Company’s assets or resource nationalization, and/or forced renegotiation or modification of ourthe Company’s existing contracts with EGPC,Egyptian General Petroleum Corporation (EGPC), or threats or acts of terrorism could materially and adversely affect ourthe Company’s business
21


and operations. Additionally, deteriorating economic conditions in Egypt have led to a shortage of foreign currency, including U.S. dollars, resulting in a decline in the timeliness of payments from EGPC. A continuation or worsening of the currency shortage in Egypt or further deterioration of economic conditions there could lead to additional payment delays, deferrals of payment, or non-payment in the future. The Company’s operations in Egypt, excluding the impacts of noncontrolling interests, contributed 16 percent of the Company’s 2023 production and accounted for 13 percent of the Company’s year-end estimated proved reserves and 25 percent of the Company’s estimated discounted future net cash flows. If conditions continue to deteriorate in Egypt, then it could materially and adversely affect the Company’s business, financial condition, and results of operations. Our operations in Egypt, excluding the impacts of a one-third noncontrolling interest, contributed 20 percent of our 2020 production and accounted for 15 percent of our year-end estimated proved reserves and 24 percent of our estimated discounted future net cash flows.
OurThe Company’s operations are sensitive to currency rate fluctuations.
OurThe Company’s operations are sensitive to fluctuations in foreign currency exchange rates, particularly between the U.S. dollar and the British pound. OurThe Company’s financial statements, presented in U.S. dollars, may be affected by foreign currency fluctuations through both translation risk and transaction risk. Volatility in exchange rates may adversely affect ourthe Company’s results of operations, particularly through the weakening of the U.S. dollar relative to other currencies.
RISKS RELATED TO THE PLANNED HOLDING COMPANY REORGANIZATION
If the Holding Company Reorganization is implemented, APA Corporation, as the parent holding company of Apache, will be dependent on the operations and funds of its subsidiaries, including Apache.
If the Holding Company Reorganization is implemented, APA Corporation will become the successor issuer to, and parent holding company of, Apache. APA Corporation will have no business operations of its own. APA Corporation’s only significant assets will be the outstanding equity interests of its subsidiaries, including Apache. As a result, APA Corporation will rely on cash flows from Apache to pay dividends with respect to its common stock and to meet its financial obligations, including to service any debt obligations that APA Corporation may incur from time to time. Legal and contractual restrictions in agreements governing future indebtedness of Apache, as well as Apache’s financial condition and future operating
29


requirements, may limit Apache’s ability to distribute cash to APA Corporation. If Apache is limited in its ability to distribute cash to APA Corporation, or if Apache’s earnings or other available assets of are not sufficient to pay distributions or make loans to APA Corporation in the amounts or at the times necessary for APA Corporation to pay dividends with respect to its common stock and/or to meet its financial obligations, then APA Corporation’s business, financial condition, cash flows, results of operations, and reputation may be materially adversely affected.
If the Holding Company Reorganization is implemented, APA Corporation may not obtain the anticipated benefits of the reorganization into a holding company structure.
If the Holding Company Reorganization is implemented, we believe that our new operating structure will allow us to focus on running our diverse businesses independently with the goal of maximizing each of the business’ potential. However, the anticipated benefits of the planned Holding Company Reorganization may not be obtained if circumstances prevent us from taking advantage of the strategic and business opportunities that we expect it may afford us. As a result, we may incur the costs of a holding company structure without realizing the anticipated benefits, which could adversely affect our business, financial condition, cash flows, and results of operations.
Management is dedicating significant effort to the new operating structure. These efforts may divert management’s focus and resources from the Company’s operations, strategic initiatives, or development opportunities, which could adversely affect our prospects, business, financial condition, cash flows, and results of operations.
GENERAL RISK FACTORS
Certain anti-takeover provisions in our charter and Delaware law could delay or prevent a hostile takeover.
Our charter authorizes our board of directors to issue preferred stock in one or more series and to determine the voting rights and dividend rights, dividend rates, liquidation preferences, conversion rights, redemption rights, including sinking fund provisions and redemption prices, and other terms and rights of each series of preferred stock. In addition, Delaware law imposes restrictions on mergers and other business combinations between us and any holder of 15 percent or more of our outstanding common stock. These provisions may deter hostile takeover attempts that could result in an acquisition of us that would have been financially beneficial to our shareholders.

As with previous changes in a volatiledemand and contribute to commodity price environment, Apache has continued to respond quickly and decisively, takingvolatility. Despite these uncertainties, the following actions:
Establishing and implementing a wide range of fit-for-purpose protocols and procedures to ensure a safe and productive work environment across the Company’s diversified global onshore and offshore operations.
Reducing upstream capital investments by over 50 percent from the comparative prior-year period, including eliminating nearly all U.S. drilling and completion activity by May 2020 and reducing planned activity in Egypt and the North Sea.
Decreasing the Company’s dividend by 90 percent beginning in the first quarter of 2020, preserving approximately $340 million of cash flow on an annualized basis and strengthening liquidity.

Highlights
During 2020, Apache2023, the Company reported a net lossincome of $2.5 billion compared to net income of $3.5 billion in 2022. Net income in 2023 was primarily impacted by lower revenues attributable to common stock of $4.9 billion, or $12.86 per share,significantly lower realized commodity prices compared to 2022. The lower revenues were partially offset by a net lossrelease of $3.6 billion, or $9.43 per share, in 2019. The results for both periods were driven by asset impairments. In 2020, the Company recorded impairments totaling $4.5 billion in connection with fair value assessments stemming from the global crude oil price collapse on lower demand and economic activity resulting from the impacts of COVID-19 and related third-party actions. The Company recorded asset impairments during 2019 of $2.9 billion, primarily related to a material reduction in planned investment at Apache’s Alpine High development that triggered fair value assessmentsmajority of the Company’s upstream Alpine High proved propertiesU.S. tax valuation allowance, resulting in a non-cash deferred income tax benefit of approximately $1.7 billion during the fourth quarter of 2023. Net income in 2022 also benefited from approximately $1.2 billion of gains from the divestiture of certain non-core mineral rights in the Delaware Basin and Altus’ associated midstream assets.completion of the BCP Business Combination.
Apache’s capital spending for the year aligned with its $1.4The Company generated $2.9 billion of cash from operating activities generated in 2020,2023, which was $1.5$1.9 billion, or 5240 percent, lower than the prior year.2022. Apache’s lower operating cash flows for 20202023 were driven by lower crude oilcommodity prices and associated revenues. The reducedrevenues and the timing of working capital investment was the result of proactive measures taken by the Company to adjust its capital budget to reflect volatile commodity prices and anticipated operating cash flows. Apache ended the year with a slightly higher cash balance of $262 million and comparable debt levels to the prior year-end, while actively managing its debt positions to reduce near-term debt maturities.items.

The Company began 2020 with seven operatedaveraged three drilling rigs and three operated completion crews in the PermianU.S. during the year in the Southern Midland Basin which were both quickly and safely reduced to zerobrought online 60 operated wells in 2023. The Company’s drilling was primarily focused on oil prospects, increasing oil production by May 2020approximately 7 percent in response to commodity price weakness.
In response to completion cost reductions whenthe U.S. compared to the first quarter of 2020, the Company reinstated two operated completion crews in theprior year. The Company’s core Permian Basin duringdevelopment program continues to represent a key growth area for the fourth quarter of 2020 to begin completing its backlog of drilled but uncompleted well inventory.U.S. assets.

In Egypt, the Company continued its drilling and workover activity with a focus on oil prospects. The Company averaged 17 drilling rigs and drilled 91 new productive wells during 2023. During 2023, gross equivalent production decreased 13 percent and net production from the Company’s Egypt assets decreased 92 percent and 1 percent, respectively, from 2019 primarily a result of natural decline given reduced drilling activity during the year.2022. The Company continues to build and enhance its robust drilling inventory in Egypt, supplemented with recent seismic acquisitions and new play concept evaluations on both new and existing acreage. As a result,acreage opportunities provided by the Egypt asset achieved a new record within the Matruh Basin with the Herunefer E-2 well, which encountered 555 feet of net pay.2021 merged concession agreement.
The Company suspended all new drilling activity in the North Sea maintained two drilling rigs during 2020 with notable discoveries at the Storr and Garten fields contributing to the two percent increase in production from 2019 to 2020. In addition, during the fourthsecond quarter of 2020, the2023. The Company’s Losgann well confirmed a Tertiary oil discovery, offsetting other operator Norwegian discoveriesinvestment program in the area. In combination with two previous undeveloped Apache discoveries in the Tertiary, Losgann will add to a comprehensive development opportunity.
In April 2020, Apache announced a significant oil discovery at the Sapakara West-1 well drilled offshore Suriname on Block 58. Sapakara West-1 was drilled to a depth of approximately 6,300 meters (approximately 20,700 feet)North Sea is now directed toward safety, base production management, and successfully tested for the presence of hydrocarbons in multiple stacked targets in the upper Cretaceous-aged Campanianasset maintenance and Santonian intervals. This follows the January 2020 announcement of a discovery at the Maka Central-1 well. During 2020, the Company submitted a plan of appraisal for both of these discoveries. Apache holds a 50 percent working interest in Block 58.
In July 2020, Apache announced a major oil discovery at the Kwaskwasi-1 well drilled offshore Suriname on Block 58. Kwaskwasi-1 was drilled to a depth of approximately 6,645 meters (approximately 21,800 feet) and successfully tested for the presence of hydrocarbons in multiple stacked targets in the upper Cretaceous-aged Campanian and Santonian intervals. Fluid samples and test results indicate at least 278 meters (approximately 912 feet) of net oil and oil/gas condensate pay in two intervals. This was the third consecutive oil discovery offshore Suriname.

Acquisition and Divestiture Activity
Over Apache’sthe Company’s history, the Companyit has repeatedly demonstrated itsthe ability to capitalize quickly and decisively on changes in its industry and economic conditions. A key component of this strategy is to continuously review and optimize Apache’s portfolio of assets in response to these changes. Most recently, Apachethe Company has completed a series of divestitures designed to enhance the Company’s portfolio and monetize nonstrategic assets and enhance Apache’s portfolio in order to allocate resources to more impactful exploration and development opportunities. These divestitures include:
U.S. LeaseholdBCP Business Combination On February 22, 2022, ALTM closed a transaction to combine with privately owned BCP Raptor Holdco LP (BCP) in an all-stock transaction. Upon closing the transaction, the combined entity was renamed Kinetik Holdings Inc. (Kinetik). The Company deconsolidated ALTM upon closing the transaction. The deconsolidation provides a number of benefits to the Company’s shareholders, including simplification of the Company’s financial reporting and enhanced comparability with its upstream-only peers, while maintaining a noncontrolling interest in future growth opportunities of Kinetik.
Delaware Basin Divestitures & Other During 2020,2022, the Company completed the sale ofa previously announced transaction to sell certain non-core producing assets and leasehold acreage, primarilymineral rights in the PermianDelaware Basin, in multiple transactions for total cash proceeds of $87 million. The Company also completed certain leasehold and property acquisitions, primarily in the Permian Basin, for total cash consideration of $4$726 million.
Suriname Joint Venture Agreement Sales of Kinetik SharesIn December 2019, Apache entered into a joint venture agreement with Total S.A. Subsequent sales of Kinetik Shares have reduced APA’s ownership in Kinetik to explore and develop Block 58 offshore Suriname. Under the terms of the agreement, Apache and Total S.A. each hold a 50approximately 9 percent working interest in Block 58. Apache operated the drilling of the first four wells and subsequently transferred operatorship of Block 58 to Total S.A. In connection with the agreement, Apache received $100 million upon closing in the fourth quarter of 2019 and $79 million upon satisfying certain closing conditions in the first quarter of 2020 for reimbursement of 50 percent of all costs incurred on Block 58 as of December 31, 2019.
Apache will also receive various other forms2023. During 2023, the Company sold a portion of consideration, including $5.0 billion of cash carry on Apache’s first $7.5 billion of appraisal and development capital, 25 percent cash carry on all of Apache’s appraisal and development capital beyond the first $7.5 billion, a $75 million cash payment upon achieving first oil production, and future contingent royalty payments from successful joint development projects.
Midcontinent/Gulf Coast Divestiture In the second quarter of 2019, Apache completed the sale of non-core, gas-weighted assets in the Woodford-SCOOP and STACK playsits Kinetik Shares for aggregate cash proceeds of approximately $223$228 million.

Crude Oil Prices A substantial portion of ourthe Company’s crude oil production is sold at prevailing market prices, which fluctuate in response to many factors that are outside of the Company’s control. Average realized crude oil prices for 20202023 were down 3419 percent compared to 2019,2022, a direct result of the decreasing benchmark oil prices over the past year resulting from the COVID-19 pandemic and related third-party actions.year. Crude oil prices realized in 20202023 averaged $39.60$80.83 per barrel.
Continued volatility in the commodity price environment reinforces the importance of the Company’s asset portfolio. While the market price received for natural gas varies among geographic areas, crude oil tends to trade within a global market. Price movementsPrices for all types and grades of crude oil generally move in the same direction.
Natural Gas Prices Natural gas, which currently has a limited global transportation system, is subject to price variances based on local supply and demand conditions. Apache’sThe Company’s primary markets include North America, Egypt, and the U.K. An overview of the market conditions in the Company’s primary gas-producing regions follows:
The Company predominantly sells its U.S. natural gas production at liquid index sales points within the United States, including to U.S. LNG export facilities, although a portion is sold to markets in Mexico. Most of the Company’s U.S. natural gas is sold on a monthly or daily basis, at either monthly or daily index-based prices. The Company’s U.S. realizations averaged $1.22$1.81 per Mcf in 2020, down2023, a 66 percent decrease from $1.26an average of $5.33 per Mcf in 2019.2022.
In Egypt, the Company’s natural gas is sold to Egyptian General Petroleum Corporation (EGPC),EGPC, primarily under an industry-pricing formula, a sliding scale based on Dated Brent crude oil with a minimum of $1.50 per MMBtu and a maximum of $2.65 per MMBtu, plus an upward adjustment for liquids content. Overall, the Company’s Egypt operations averaged $2.79$2.91 per Mcf in 2020,2023, a 12 percent decreaseincrease from 2019.an average of $2.85 per Mcf in 2022.

The Company’s worldwide NGL production increased 6decreased 3 Mb/d compared to 2019,2022, primarily a result of the Alpine High development in recent years.
Altus Midstream Revenues
Apache beneficially owns approximately 79 percent of Altus’ outstanding voting common stock. Altus owns and operates a midstream energy asset network in the Permian Basin of West Texas primarily to service Apache’snatural production from its Alpine High resource play, which commenced production in May 2017.
Altus Midstream generates revenue by providing fee-based natural gas gathering, compression, processing, and transmission services. For the years ended December 31, 2020 and 2019, Altus Midstream’s services revenues generated through its fee-based contractual arrangements with Apache totaled $145 million and $136 million, respectively. These affiliated revenues are eliminated upon consolidation. The increase compared to the prior year was primarily driven by higher throughput of rich natural gas volumes at Alpine High due to increased capacity as a result of three cryogenic processing trains coming on line starting in the second quarter of 2019,decline across all assets, partially offset by lower throughput of lean natural gas volumes.increased drilling activity and recompletions and less maintenance downtime in the North Sea.
Purchased Oil and Gas Sales
Purchased oil and gas sales increased $222represent volumes primarily attributable to domestic gas purchases that were sold by the Company to fulfill natural gas takeaway obligations and delivery commitments. In 2023, in order to diversify the pricing received for the sale of its natural gas, the Company sold a portion of its purchased gas at international gas prices. Sales related to purchased volumes decreased $961 million for the year ended December 31, 20202023 to $894 million from $176 million to $398 million.$1.9 billion in 2022. Purchased oil and gas sales were primarilypartially offset by associated purchase costs of $357$742 million and $142 million$1.8 billion for the years ended December 31, 20202023 and 2019,2022, respectively. The decrease in purchased oil and gas sales is primarily a result of lower average domestic natural gas prices during 2023 compared to 2022.

Lease Operating Expenses (LOE)
LOE includes several key components, such as direct operating costs, repairs and maintenance, and workover costs. Direct operating costs generally trend with commodity prices and are impacted by the type of commodity produced and the location of properties (i.e., offshore, onshore, remote locations, etc.). Fluctuations in commodity prices impact operating cost elements both directly and indirectly. They directly impact costs such as power, fuel, and chemicals, which are commodity price based. Commodity prices also affect industry activity and demand, thus indirectly impacting the cost of items such as rig rates, labor, boats, helicopters, materials, and supplies. Crude oil, which accounted for 4950 percent of the Company’s total 20202023 production, is inherently more expensive to produce than natural gas. Repair and maintenance costs are typically higher on offshore properties.
During 2020,2023, LOE decreased $320$38 million, or 223 percent, compared to 2019.2022. On a per-boe basis, LOE decreased $1.38, or 16 percent,remained essentially flat compared to 2019, from $8.38 per boe to $7.00 per boe,2022. The decrease in absolute costs was driven by reducedlower average foreign currency exchange impacts against the U.S. dollar and decreased workover activity primarily in the North Sea. These decreases were mostly offset by higher labor costs and fuelother operating costs associatedtrending with lower commodity prices, the Company’s organizational redesign, and other cost cutting efforts. In addition, absolute dollar costs are lower in the current year as a result of the divestitures of the Company’s Woodford-SCOOP and STACK plays and western Anadarko Basin assets in the U.S. in the third quarter of 2019.general inflation across all regions.

Third-party2022, primarily the result of lower upstream processing and transmission costs, partially offset by impacts of the BCP Business Combination. Upstream processing and transmission costs decreased $14$55 million from 2022, primarily driven by a decrease in contracted pricing andnatural gas production volumes when compared to the prior-year period. Costs for services provided by ALTM in 2022 prior to the BCP Business Combination totaling $18 million were eliminated in the Company’s sale of non-core assets in Oklahomaconsolidated financial statements and Texas. Midstream service affiliate costs increased $9 million compared to 2019, primarily driven by higher throughput of rich natural gas volumes at Alpine High. Midstream operating expenses, incurred primarily by Altus, decreased $18 million compared to 2019, primarily driven by increased operational efficiencyreflected as a result of transitioning from mechanical refrigeration units to Altus’ centralized Diamond cryogenic complex starting“Intersegment eliminations” in the second quartertable above.

Purchased Oil and Gas Costs
Purchased oil and gas costs increased $215decreased $1.0 billion for the year ended December 31, 2023, to $742 million from $1.8 billion in 2022. The decrease is a result of lower average domestic natural gas prices during 2023 compared to 2019,the prior year. Purchased oil and gas costs were more than offset by associated sales to fulfill natural gas takeaway obligations and delivery commitments totaling $398$894 million for the year ended 2020.2023, as discussed above.
Taxes Other Than Income
Taxes other than income primarily consist of severance taxes on onshore properties and in state waters off the coast of the U.S. and ad valorem taxes on U.S. properties. Severance taxes are generally based on a percentage of oil and gas production revenues. The Company is also subject to a variety of other taxes, including U.S. franchise taxes.
Taxes other than income decreased $84$64 million compared to 2019,2022, primarily from lower severance taxes driven by lower commodity prices and the divestiture of the Company’s non-core assets in Oklahoma and Texas.lower ad valorem tax rates.

In recent years, the Company has streamlined its portfolio through strategic divestitures and centralized certain operational activities in an effort to capture greater efficiencies and cost savings through shared services. During the second half of 2019, management initiated a comprehensive redesign of Apache’s organizational structure and operations that it believes will better position the Company to be competitive for the long-term and further reduce recurring costs. Reorganization efforts were substantially completed in 2020, and as a result of the reorganization, Apache has achieved an estimated cost savings of more than $400 million annually.
Depreciation, Depletion and Amortization (DD&A)

Theassets and the remeasurement of taxes in the U.K. as a result of the enactment of Finance Act 2023 on January 10, 2023. During 2022, the Company’s year-to-date 2019 effective income tax rate was primarily impacted by an increasea deferred tax expense related to the remeasurement of taxes in the U.K. as a result of the enactment of the Energy (Oil and Gas) Profits Levy Act of 2022 (the Energy Profits Levy) on July 14, 2022, and a decrease in the amount of valuation allowance against its U.S. deferred tax assets.
On July 14, 2022, the Energy Profits Levy was enacted, receiving Royal Assent. Under the law, an additional levy was assessed at a 25 percent rate and is effective for the period of May 26, 2022, through December 31, 2025. The Finance Act 2023 included amendments to the Energy Profits Levy that increased the levy from a 25 percent rate to a 35 percent rate, effective for the period of January 1, 2023 through March 31, 2028. Under accounting principles generally accepted in the U.S., the financial statement impact of new legislation is recorded in the period of enactment. As a result, the Company recorded a full valuation allowance against its U.S. net deferred tax assetsexpense of $208 million and $174 million related to the remeasurement of the U.K. deferred tax liability in 2022 and 2023, respectively.
On August 16, 2022, the U.S. enacted the Inflation Reduction Act of 2022 (IRA). The IRA includes a new 15 percent corporate alternative minimum tax (CAMT) on applicable corporations with an average annual adjusted financial statement income that exceeds $1 billion for any three consecutive years preceding the tax year at issue. The CAMT is effective for tax years beginning after December 31, 2022. The Company is not an applicable corporation in 2023 but will be subject to CAMT beginning on January 1, 2024. The Company is continuing to evaluate the provisions of the IRA and its effects on the Company’s consolidated financial statements.

In December 2021, the Organisation for Economic Co-operation and Development (OECD) released Model Rules under the Pillar Two framework, which imposes a 15 percent global minimum tax on large corporations. Such Model Rules have been adopted in certain jurisdictions in which the Company operates, including the United Kingdom, with an effective date of January 1, 2024. While the Company does not anticipate that Pillar Two will have a material impact on its effective tax rate, the Company will continue to maintainevaluate the potential impacts of enacted and pending legislation in the jurisdictions in which it operates.
The Company assesses the available positive and negative evidence to estimate whether sufficient future taxable income will be generated to realize the existing deferred tax assets. The Company showed positive income over the three-year period ended December 31, 2023. During the fourth quarter of 2023, as a fullresult of increases in projections of future taxable income and the absence of objective negative evidence such as a cumulative loss in recent years, the Company determined there was sufficient positive evidence to release a majority of the U.S. valuation allowance, on itswhich resulted in a non-cash deferred income tax benefit of $1.7 billion.

ApacheThe Company and its subsidiaries are subject to U.S. federal income tax as well as income or capital taxes in various statestates and foreign jurisdictions. The Company’s tax reserves are related to tax years that may be subject to examination by the relevant taxing authority. On September 26, 2022, the Company received a Statutory Notice of Deficiency from the IRS disallowing certain net operating loss carryback and research and development credit refund claims. As a result of the disallowance, on December 14, 2022, the Company filed a petition with the U.S. Tax Court challenging the tax adjustments and requesting a redetermination of the deficiencies stated in the notice. The Company is currently under audit by the Internal Revenue Service (IRS) for the 2014-2017 tax years and is also under audit in various states and foreign jurisdictions as part of its normal course of business.
Capital and Operational Outlook
The Company continues to prudently manage its capital program against a volatile price environment and the prolonged effects of the COVID-19 pandemic. In response to the current crises, Apache’s immediate course of action has been to actively reduce its cost structure, protect its balance sheet, and manage operations to preserve cash flow. The Company plans to maintain a conservative investment approach into 2021, having announced an upstream capital program of $1.1 billion. The program consists of approximately $900 million for development activities and approximately $200 million for exploration, predominantly in Suriname.
The 2021 capital program assumes an average WTI price of $45 per barrel and a Henry Hub natural gas price of $3.00 per Mcf. In 2020, a higher percentage of development capital was directed toward international projects that generate better returns in a lower price environment. With the improvement in oil prices, the Company is returning to a modest level of activity in the U.S. Under the capital budget for 2021, activity includes:
continuing to advance exploratory and appraisal programs in Suriname under the terms of the Company’s joint venture with Total S.A.;
running one rig in the Permian Basin, with the expectation to add a second rig in the middle of the year, while resuming completion activity for its previously drilled but uncompleted well inventory in response to significantly lower service costs;
continuing to run a five rig drilling program in Egypt with the ability to quickly flex spending as conditions warrant; and
maintaining a capital program in the North Sea relatively unchanged from the prior year with one floating rig and one platform crew.
The Company’s proactive reduction in capital spending in 2020 directly impacted global oil volumes which decreased by 17 percent from the fourth quarter of 2019 to the fourth quarter of 2020. BasedPotential Decommissioning Obligations on its 2021 upstream investment plan and allocation, the Company is projecting a more moderate decline of one percent for the comparable 2021 period. Forecasting into 2022 and future years, Apache’s goal is to establish a development capital investment budget that will, at a minimum, at least sustain production volumes for the longer-term.
Apache’s strategic approach and multi-year outlook prioritizes retaining cash flow to reduce outstanding debt, focusing on long-term returns over short-term growth, aggressively managing its cost structure, and advancing exploration and appraisal activities in Suriname.

The Company’s diversified global portfolio provides the ability to quickly optimize capital allocation as market conditions change. The current crisis, however, is still evolving and may become more severe and complex. As a result, the COVID-19 pandemic may still materially and adversely affect Apache’s results in a manner that is either not currently known or that the Company does not currently consider to be a significant risk to its business. For additional information about the business risks relating to the COVID-19 pandemic and related governmental actions, refer to Part I, Item 1A—Risk Factors of this Annual Report on Form 10-K.
Separate from the Company’s upstream oil and gas activities, capital spending for Altus’ gathering and processing assets totaled $28 million in 2020, down from $327 million in 2019 when a majority of the midstream infrastructure construction was completed. Altus management believes its existing gathering, processing, and transmission infrastructure capacity is capable of fulfilling its midstream contracts to service Apache’s production from Alpine High and any third-party customers. As such, remaining capital requirements for its existing infrastructure assets during 2021 and 2022 are anticipated to be minimal.
Additionally, during the years ended December 31, 2020 and 2019, Altus made cash contributions totaling $327 million and $501 million, respectively, for its equity interests in the following Equity Method Interest Pipelines:
16 percent in the Gulf Coast Express natural gas pipeline (GCX);
15 percent in the EPIC crude pipeline (EPIC);
an approximate 26.7 percent in the Permian Highway natural gas pipeline (PHP); and
33 percent in the Shin Oak NGL pipeline (Shin Oak).
Altus estimates it will incur approximately $30 million of additional capital contributions during 2021 for its equity interest associated with the commissioning and remaining construction costs in the Equity Method Interest Pipelines, primarily associated with PHP. During 2020, Altus’ primary sources of cash were borrowings under the revolving credit facility, cash generated from operations, distributions from the Equity Method Interest Pipelines, and proceeds from the sale of assets. Based on Altus’ current financial plan and related assumptions, it believes that cash from operations, a reduced capital program for its midstream infrastructure, and distributions from equity method interests will generate cash flows significantly in excess of capital expenditures that will provide sufficient cash to fund its planned dividend program during 2021.
For further information on the Equity Method Interest Pipelines, refer to Note 6—Equity Method Interests in the Notes to Consolidated Financial Statements set forth in Part IV, Item 15 of this Annual Report on Form 10-K.
Capital Resources and Liquidity
Operating cash flows are the Company’s primary source of liquidity. Apache’s operating cash flows, both in the short-term and the long-term, are impacted by highly volatile oil and natural gas prices, as well as costs and sales volumes. Significant changes in commodity prices impact Apache’s revenues, earnings and cash flows. These changes potentially impact Apache’s liquidity if costs do not trend with changes in commodity prices. Historically, costs have trended with commodity prices, albeit on a lag. Sales volumes also impact cash flows; however, they have a less volatile impact in the short term.
Apache’s long-term operating cash flows are dependent on reserve replacement and the level of costs required for ongoing operations. Cash investments are required to fund activity necessary to offset the inherent declines in production and proved crude oil and natural gas reserves. Future success in maintaining and growing reserves and production is highly dependent on the success of Apache’s drilling program and its ability to add reserves economically. Changes in commodity prices also impact estimated quantities of proved reserves. For the year ended December 31, 2020, Apache recognized negative reserve revisions of approximately 7 percent of its year-end 2019 estimated proved reserves as a result of lower prices. The Company’s estimates of proved reserves, proved developed reserves, and PUD reserves as of December 31, 2020, 2019, and 2018, changes in estimated proved reserves during the last three years, and estimates of future net cash flows from proved reserves are contained in Note 18—Supplemental Oil and Gas Disclosures (Unaudited) in the Notes to Consolidated Financial Statements set forth in Part IV, Item 15 of this Annual Report on Form 10-K.
Combined with proactive measures to adjust its capital budget, decrease its dividend, protect further downside price risk through entering into new hedge positions, and reduce its operating cost structure in the current volatile commodity price environment, Apache believes the liquidity and capital resource alternatives available to the Company will be adequate to fund its operations and provide flexibility until commodity prices and industry conditions improve. This includes supporting the Company’s capital development program, repayment of debt maturities, payment of dividends, and any amount that may ultimately be paid in connection with commitments and contingencies.

The Company may also elect to utilize available cash on hand, committed borrowing capacity, access to both debt and equity capital markets, or proceeds from the sale of nonstrategic assets for all other liquidity and capital resource needs.

Sources of Cash and Cash Equivalents
Net Cash Provided by Operating Activities Operating cash flows are the Company’s primary source of capital and liquidity and are impacted, both in the short term and the long term, by volatile crude oil and natural gas prices. The factors that determine operating cash flows are largely the same as those that affect net earnings, with the exception of non-cash expenses such as DD&A, exploratory dry hole expense, asset impairments, asset retirement obligation (ARO) accretion, and deferred income tax expense.
Net cash provided by operating activities for the year ended December 31, 2020 totaled $1.4 billion, down $1.5 billion from the year ended December 31, 2019. The decrease primarily reflects lower commodity prices compared to the prior year.
For a detailed discussion of commodity prices, production, and operating expenses, refer to “Results of Operations” in this Item 7. For additional detail on the changes in operating assets and liabilities and the non-cash expenses that do not impact net cash provided by operating activities, refer to the Statement of Consolidated Cash Flows in the Consolidated Financial Statements set forth in Part IV, Item 15 of this Annual Report on Form 10-K.
Proceeds from Apache Credit Facility, Net As of December 31, 2020, there were $150 million of borrowings outstanding under Apache’s credit facility, which is classified as long-term debt. The Company had no borrowings under the revolver as of December 31, 2019.
45


Proceeds from Altus Credit Facility, Net The initial construction of Altus’ gathering and processing assets and the exercise of its Pipeline Options for its equity interests in the Equity Method Interest Pipelines has historically required capital expenditures in excess of Altus’ cash on hand and operational cash flows. During the years ended December 31, 2020 and 2019, Altus Midstream borrowed $228 million and $396 million, respectively, under its revolving credit facility. With the initial midstream infrastructure construction complete and each of Shin Oak, GCX, PHP, and EPIC now in service, the Company anticipates that Altus’ existing capital resources will be sufficient to fund its continuing obligations and planned dividend program during 2021.
Proceeds from Asset Divestitures The Company recorded proceeds from non-core asset divestitures totaling $166 million and $718 million for the years ended December 31, 2020 and 2019, respectively. For more information regarding the Company’s acquisitions and divestitures, refer to Note 2—Acquisitions and Divestitures in the Notes to Consolidated Financial Statements in Part IV set forth in Part IV, Item 15 of this Annual Report on Form 10-K.
Fixed-Rate Debt Borrowings On August 17, 2020, the Company closed offerings of $1.25 billion in aggregate principal amount of senior unsecured notes, comprised of $500 million in aggregate principal amount of 4.625% notes due 2025 and $750 million in aggregate principal amount of 4.875% notes due 2027. The senior unsecured notes are redeemable at any time, in whole or in part, at Apache’s option, at the applicable redemption price. The net proceeds from the sale of the notes were used to purchase certain outstanding notes in cash tender offers, repay a portion of outstanding borrowings under the Company’s senior revolving credit facility, and for general corporate purposes.
On June 19, 2019, Apache closed offerings of $1.0 billion in aggregate principal amount of senior unsecured notes, comprised of $600 million in aggregate principal amount of 4.250% notes due January 15, 2030 (2030 notes) and $400 million in aggregate principal amount of 5.350% notes due July 1, 2049 (2049 notes). The notes are redeemable at any time, in whole or in part, at Apache’s option, subject to a make-whole premium. The aggregate net proceeds of $989 million from the sale of the notes were used to purchase certain outstanding notes in cash tender offers and for general corporate purposes.
Redeemable Noncontrolling Interest - Altus Preferred Unit Limited Partners On June 12, 2019, Altus Midstream LP issued and sold Series A Cumulative Redeemable Preferred Units for an aggregate issue price of $625 million in a private offering exempt from the registration requirements of the Securities Act of 1933, as amended. Altus Midstream LP received approximately $611 million in cash proceeds from the sale after deducting transaction costs and discounts to certain purchasers. For more information, refer to Note 13—Redeemable Noncontrolling Interest - Altus in the Notes to Consolidated Financial Statements set forth in Part IV, Item 15 of this Annual Report on Form 10-K.
Uses of Cash and Cash Equivalents
Additions to Oil & Gas Property Exploration and development cash expenditures were $1.3 billion and $2.6 billion for the years ended December 31, 2020 and 2019, respectively. The decrease in capital investment is reflective of the Company’s reduced capital program as the Company eliminated nearly all drilling and completion activities in the U.S. by May 2020 in response to commodity price impacts stemming from the COVID-19 pandemic. A majority of the current year expenditures shifted from the Company’s Permian Basin assets to its Egypt assets over the second half of 2020. The Company operated an average of 12 drilling rigs during 2020 compared to 23 drilling rigs during 2019.
Additions to Altus Gathering, Processing, and Transmission (GPT) Facilities The Company’s cash expenditures for GPT facilities totaled $28 million and $327 million during 2020 and 2019, respectively, nearly all comprising midstream infrastructure expenditures incurred by Altus, which were substantially completed as of December 31, 2019. Altus management believes its existing GPT infrastructure capacity is capable of fulfilling its midstream contracts to service Apache’s production from Alpine High and any third-party customers. As such, Altus expects capital requirements for its existing infrastructure assets for 2021 and 2022 to be minimal.
Leasehold and Property Acquisitions During 2020 and 2019, the Company completed leasehold and property acquisitions, primarily in the Permian Basin, for total cash consideration of $4 million and $40 million, respectively.
Contributions to Altus Equity Method Interests Altus made contributions of $327 million and $501 million during 2020 and 2019, respectively, for equity interests in the Equity Method Interest Pipelines. For more information regarding the Company’s equity method interests, refer to Note 6—Equity Method Interests in the Notes to Consolidated Financial Statements set forth in Part IV, Item 15 of this Annual Report on Form 10-K.

Acquisitions of Altus Equity Method Interests Altus made acquisitions of equity method interests totaling $671 million during the year ended December 31, 2019. For more information regarding the Company’s equity method interests, refer to Note 6—Equity Method Interests in the Notes to Consolidated Financial Statements set forth in Part IV, Item 15 of this Annual Report on Form 10-K.
Payments on Fixed-Rate Debt On August 18, 2020, the Company closed cash tender offers for certain outstanding notes. The Company accepted for purchase $644 million aggregate principal amount of certain notes covered by the tender offers. The Company paid holders an aggregate $644 million reflecting principal, aggregate discount to par of $38 million, early tender premium of $32 million, and accrued and unpaid interest of $6 million. The Company recorded a net gain of $2 million on extinguishment of debt, including an acceleration of unamortized debt discount and issuance costs, in connection with the note purchases.
During 2020, the Company purchased in the open market and canceled senior notes issued under its indentures in an aggregate principal amount of $588 million for an aggregate purchase price of $428 million in cash, including accrued interest and broker fees, reflecting a discount to par of an aggregate $168 million. These repurchases resulted in a $158 million net gain on extinguishment of debt. The net gain includes an acceleration of related discount and debt issuance costs. Additionally, on November 3, 2020, Apache redeemed the $183 million of 3.625% senior notes due February 1, 2021 at a redemption price equal to 100 percent of their principal amount, plus accrued and unpaid interest to the redemption date. The repurchases were financed by borrowings under the Company’s revolving credit facility.
On June 21, 2019, the Company closed cash tender offers for certain outstanding notes. Apache accepted for purchase $932 million aggregate principal amount of notes for approximately $1.0 billion, which included principal, the net premium to par, and an early tender premium totaling $28 million, as well as accrued and unpaid interest of $14 million. The Company recorded a net loss of $75 million on extinguishment of debt, including $7 million of unamortized debt issuance costs and discounts, in connection with the note purchases. Additionally, on July 1, 2019, Apache’s 7.625% senior notes in original principal amount of $150 million matured and were repaid.
Dividends The Company paid $123 million and $376 million cash dividends on its common stock for the years ended December 31, 2020 and 2019, respectively. In the first quarter of 2020, Apache’s Board of Directors approved a reduction in the Company’s quarterly dividend per share from $0.25 per share to $0.025 per share, effective for all dividends payable after March 12, 2020.
Distributions to Noncontrolling Interests - Egypt Sinopec International Petroleum Exploration and Production Corporation (Sinopec) holds a one-third minority participation interest in Apache’s oil and gas operations in Egypt. The Company made cash distributions totaling $91 million and $305 million to Sinopec during the years ended December 31, 2020 and 2019, respectively.
Distributions to Altus Preferred Units limited partners Altus Midstream LP paid cash distributions of $23 million to its limited partners holding Preferred Units for the year ended December 31, 2020. No cash distributions were made during 2019. For more information regarding the Preferred Units, refer to Note 13Redeemable Noncontrolling Interest - Altus in the Notes to Consolidated Financial Statements set forth in Part IV, Item 15 of this Annual Report on Form 10-K.

Cash and Cash Equivalents As of December 31, 2020, the Company had $262 million in cash and cash equivalents, of which approximately $24 million was held by Altus. The majority of the Company’s cash is invested in highly liquid, investment-grade instruments with maturities of three months or less at the time of purchase.

Debt As of December 31, 2020, outstanding debt, which consisted of notes, debentures, credit facility borrowings, and finance lease obligations, totaled $8.8 billion. As of December 31, 2020, current debt included $2 million of finance lease obligations. Apache intends to reduce debt outstanding under its indentures from time to time.
Available Credit Facilities In March 2018, the Company entered into a revolving credit facility with commitments totaling $4.0 billion. In March 2019, the term of this facility was extended by one year to March 2024 (subject to Apache’s remaining one-year extension option) pursuant to Apache’s exercise of an extension option. The Company can increase commitments up to $5.0 billion by adding new lenders or obtaining the consent of any increasing existing lenders. The facility includes a letter of credit subfacility of up to $3.0 billion, of which $2.08 billion was committed as of December 31, 2020. The facility is for general corporate purposes. Letters of credit are available for security needs, including in respect of North Sea decommissioning obligations. The facility has no collateral requirements, is not subject to borrowing base redetermination, and has no drawdown restrictions or prepayment obligations in the event of a decline in credit ratings.
As of December 31, 2020, there were $150 million of borrowings and an aggregate £633 million and $40 million in letters of credit outstanding under this facility. As of December 31, 2019, there were no borrowings or letters of credit outstanding under this facility. The £633 million in outstanding letters of credit were issued to support North Sea decommissioning obligations, the terms of which required such support after Standard & Poor’s reduced the Company’s credit rating from BBB to BB+ on March 26, 2020.
At Apache’s option, the interest rate per annum for borrowings under the 2018 facility is either a base rate, as defined, plus a margin, or the London Inter-bank Offered Rate (LIBOR), plus a margin. Apache also pays quarterly a facility fee at a per annum rate on total commitments. The margins and the facility fee vary based upon the Company’s senior long-term debt rating. At December 31, 2020, the base rate margin was 0.5 percent, the LIBOR margin was 1.50 percent, and the facility fee was 0.25 percent. A commission is payable quarterly to lenders on the face amount of each outstanding letter of credit at a per annum rate equal to the LIBOR margin then in effect. Customary letter of credit fronting fees and other charges are payable to issuing banks.
The financial covenants of the credit facility require Apache to maintain an adjusted debt-to-capital ratio of not greater than 60 percent at the end of any fiscal quarter. For purposes of this calculation, capital excludes the effects of non-cash write-downs, impairments, and related charges occurring after June 30, 2015. At December 31, 2020, Apache’s debt-to-capital ratio as calculated under the credit facility was 32 percent. The 2018 facility’s negative covenants restrict the ability of Apache and its subsidiaries to create liens securing debt on their hydrocarbon-related assets, with exceptions for liens typically arising in the oil and gas industry; liens securing debt incurred to finance the acquisition, construction, improvement, or capital lease of assets, provided that such debt, when incurred, does not exceed the subject purchase price and costs, as applicable, and related expenses; liens on subsidiary assets located outside of the United States and Canada; and liens arising as a matter of law, such as tax and mechanics’ liens. Apache also may incur liens on assets if debt secured thereby does not exceed 15 percent of Apache’s consolidated net tangible assets, or approximately $1.7 billion as of December 31, 2020. Negative covenants also restrict Apache’s ability to merge with another entity unless it is the surviving entity, dispose of substantially all of its assets, and guarantee debt of non-consolidated entities in excess of the stated threshold.
In November 2018, Altus Midstream LP entered into a revolving credit facility for general corporate purposes that matures in November 2023 (subject to Altus Midstream LP’s two, one-year extension options). The agreement for this facility, as amended, provides aggregate commitments from a syndicate of banks of $800 million. All aggregate commitments include a letter of credit subfacility of up to $100 million and a swingline loan subfacility of up to $100 million. Altus Midstream LP may increase commitments up to an aggregate $1.5 billion by adding new lenders or obtaining the consent of any increasing existing lenders. As of December 31, 2020 and 2019, there were $624 million and $396 million, respectively, of borrowings and no letters of credit outstanding under this facility.
48


The agreement for Altus Midstream LP’s credit facility, as amended, restricts distributions in respect of capital to Apache and other unit holders in certain circumstances. Unless the Leverage Ratio is less than or equal to 4.00:1.00, the agreement limits such distributions to $30 million per calendar year until either (i) the consolidated net income of Altus Midstream LP and its restricted subsidiaries, as adjusted pursuant to the agreement, for three consecutive calendar months equals or exceeds $350.0 million on an annualized basis or (ii) Altus Midstream LP has a specified senior long-term debt rating; in addition, before the occurrence of one of those two events, the Leverage Ratio must be less than or equal to 5.00:1.00. In no event can any distribution be made that would, after giving effect to it on a pro forma basis, result in a Leverage Ratio greater than (i) 5.00:1.00 or (ii) for a specified period after a qualifying acquisition, 5.50:1.00. The Leverage Ratio is the ratio of (1) the consolidated indebtedness of Altus Midstream LP and its restricted subsidiaries to (2) EBITDA (as defined in the agreement) of Altus Midstream LP and its restricted subsidiaries for the 12-month period ending immediately before the determination date. The Leverage Ratio as of December 31, 2020 was less than 4.00:1.00. 
The terms of Altus Midstream LP’s Series A Cumulative Redeemable Preferred Units also contain certain restrictions on distributions in respect of capital, including the common units held by Apache and any other units that rank junior to the Preferred Units with respect to distributions or distributions upon liquidation. Refer to Note 13—Redeemable Noncontrolling Interest - Altus set forth in Part IV, Item 15 of this Annual Report on Form 10-K for further information. In addition, the amount of any cash distributions to Altus Midstream LP by any entity in which it has an interest accounted for by the equity method is subject to such entity’s compliance with the terms of any debt or other agreements by which it may be bound, which in turn may impact the amount of funds available for distribution by Altus Midstream LP to its partners. 
The Altus Midstream LP credit facility is unsecured and is not guaranteed by Apache or any of Apache’s other subsidiaries.
There are no clauses in either the agreement for Apache’s 2018 credit facility or for Altus Midstream LP’s 2018 credit facility that permit the lenders to accelerate payments or refuse to lend based on unspecified material adverse changes. These agreements do not have drawdown restrictions or prepayment    obligations in the event of a decline in credit ratings. However, each agreement allows the lenders to accelerate payment maturity and terminate lending and issuance commitments for nonpayment and other breaches, and if a borrower or any of its subsidiaries defaults on other indebtedness in excess of the stated threshold, is insolvent, or has any unpaid, non-appealable judgment against it for payment of money in excess of the stated threshold. Lenders may also accelerate payment maturity and terminate lending and issuance commitments under the applicable agreement if Apache or Altus Midstream LP, as applicable, undergoes a specified change in control or any borrower has specified pension plan liabilities in excess of the stated threshold. Each of Apache and Altus Midstream LP was in compliance with the terms of its 2018 credit facility as of December 31, 2020.
There is no assurance of the terms upon which potential lenders under future credit facilities will make loans or other extensions of credit available to Apache or its subsidiaries or the composition of such lenders.
There is no assurance that the financial condition of banks with lending commitments to Apache or Altus Midstream LP will not deteriorate. We closely monitor the ratings of the banks in our bank groups. Having large bank groups allows the Company to mitigate the potential impact of any bank’s failure to honor its lending commitment.
Commercial Paper Program Apache’s $3.5 billion commercial paper program, which is subject to market availability, facilitates Apache borrowing funds for up to 270 days. As a result of downgrades in Apache’s credit ratings during 2020, the Company does not expect that its commercial paper program will be cost competitive with its other financing alternatives and does not anticipate using it under such circumstances. As of December 31, 2020 and 2019, the Company had no commercial paper outstanding.

(1)Includes outstanding principal amounts at December 31, 2020. This table does not include future commitment fees, interest expense, or other fees on the Company’s credit facilities because they are floating rate instruments, and management cannot determine with accuracy the timing of future loan advances, repayments, or future interest rates to be charged.
(2)Amounts represent the Company’s finance lease obligation related to the Company’s Midland, Texas regional office building.
(3)Amounts represent future lease payments associated with oil and gas operations inclusive of amounts billable to partners and other working interest owners. Such payments may be capitalized as a component of oil and gas properties and subsequently depreciated, impaired, or written off as exploration expense.
(4)Amounts represent any agreements to purchase goods or services that are enforceable and legally binding and that specify all significant terms. These include minimum commitments associated with take-or-pay contracts, NGL processing agreements, drilling work program commitments, and agreements to secure capacity rights on third-party pipelines. Amounts exclude certain product purchase obligations related to marketing and trading activities for which there are no minimum purchase requirements or the amounts are not fixed or determinable. Total costs incurred under take-or-pay and throughput obligations were $120 million, $111 million, and $132 million for 2020, 2019, and 2018, respectively.
(5)This table does not include the Company’s liability for dismantlement, abandonment, and restoration costs of oil and gas properties or pension or postretirement benefit obligations. For additional information regarding these liabilities, please see Notes 8Asset RetirementObligation and Note 12Retirement and Deferred Compensation Plans, respectively, in the Notes to Consolidated Financial Statements set forth in Part IV, Item 15 of this Annual Report on Form 10-K.
Apache is also subject to various contingent obligations that become payable only if certain events or rulings were to occur. The inherent uncertainty surrounding the timing of and monetary impact associated with these events or rulings prevents any meaningful accurate measurement, which is necessary to assess settlements resulting from litigation. Apache’s management believes that it has adequately reserved for its contingent obligations, including approximately $2 million for environmental remediation and approximately $70 million for various contingent legal liabilities. For a detailed discussion of the Company’s lease obligations, purchase obligations, environmental and legal contingencies, and other commitments, please see Note 11—Commitments and Contingencies and Note 12Retirement and Deferred Compensation Plans in the Notes to Consolidated Financial Statements set forth in Part IV, Item 15 of this Annual Report on Form 10-K.
As further described above under “Capital and Operational Outlook,” Altus Midstream LP and/or its subsidiaries have exercised four of the five Pipeline Options to acquire equity interests in the Equity Method Interest Pipelines. The fifth Pipeline Option to acquire an equity interest in a separate intra-basin NGL pipeline was not exercised and expired on March 2, 2020. Following the exercise of each Pipeline Option, Altus Midstream LP and/or its subsidiaries may be required to fund future capital expenditures for its equity interest share in the development of the applicable pipeline. The Company estimates that Altus, based on its equity interests in each pipeline, will incur approximately $30 million of additional capital contributions for its equity interests during 2021.

With respect to oil and gas operations in the Gulf of Mexico, the Bureau of Ocean Energy Management (BOEM) issued a Notice to Lessees (NTL No. 2016-N01) significantly revising the obligations of companies operating in the Gulf of Mexico to provide supplemental assurances of performance with respect to plugging, abandonment, and decommissioning obligations associated with wells, platforms, structures, and facilities located upon or used in connection with such companies’ oil and gas leases. While the NTL was paused in mid-2017 and is currently listed on BOEM’s website as “rescinded,” if reinstated, the NTL will likely require that Apache provide additional security to BOEM with respect to plugging, abandonment, and decommissioning obligations relating to Apache’s current ownership interests in various Gulf of Mexico leases. The Company is working closely with BOEM to make arrangements for the provision of such additional required security, if such security becomes necessary under the NTL. Additionally, the Company is not able to predict the effect that these changes might have on counterparties to which Apache has sold Gulf of Mexico assets or with whom Apache has joint ownership. Such changes could cause the bonding obligations of such parties to increase substantially, thereby causing a significant impact on the counterparties’ solvency and ability to continue as a going concern.
Potential Asset Retirement Obligations
The Company has potential exposure to future obligations related to divested properties. Apache has divested various leases, wells, and facilities located in the Gulf of Mexico (GOM) where the purchasers typically assume all obligations to plug, abandon, and decommission the associated wells, structures, and facilities acquired. One or more of the counterparties in these transactions could, either as a result of the severe decline in oil and natural gas prices or other factors related to the historical or future operations of their respective businesses, face financial problems that may have a significant impact on their solvency and ability to continue as a going concern. If a purchaser of our Gulf of Mexicosuch GOM assets becomes the subject of a case or proceeding under relevant insolvency laws or otherwise fails to perform required abandonment obligations, Apache could be required to perform such actions under applicable federal laws and regulations. In such event, Apache may be forced to use available cash to cover the costs of such liabilities and obligations should they arise.
In 2013, the CompanyApache sold its Gulf of MexicoGOM Shelf operations and properties (Transferred Assets)and its GOM operating subsidiary, GOM Shelf LLC (GOM Shelf) to Fieldwood Energy LLC (Fieldwood). Under the terms of the purchase agreement, the CompanyApache received cash consideration of $3.75 billion and Fieldwood assumed $1.5 billion of discounted asset abandonment liabilities as of the disposition date.obligation to decommission the properties held by GOM Shelf and the properties acquired from Apache and its other subsidiaries (collectively, the Legacy GOM Assets). In respect of such abandonment liabilities,obligations, Fieldwood posted letters of credit in favor of the CompanyApache (Letters of Credit) and established trust accounts (Trust A and Trust B) of which Apache was a trust account (Trust A),beneficiary and which iswere funded by a 10 percenttwo net profits interestinterests (NPIs) depending on future oil prices and of which the Company is the beneficiary.prices. On February 14, 2018, Fieldwood filed for protection under Chapter 11 of the U.S. Bankruptcy Code. In connection with the 2018 bankruptcy, Fieldwood confirmed a plan under which the CompanyApache agreed, inter alia, to (i) accept bonds in exchange for certain of the Letters of Credit. Currently,Credit and (ii) amend the Company holdsTrust A trust agreement and one of the NPIs to consolidate the trusts into a single Trust (Trust A) funded by both remaining NPIs. Following the 2018 reorganization of Fieldwood, Apache held two bonds (Bonds) and the remainingfive Letters of Credit to securesecuring Fieldwood’s asset retirement obligations (AROs) on the TransferredLegacy GOM Assets as and when such abandonment and decommissioning obligations areApache is required to be performedperform or pay for decommissioning any Legacy GOM Asset over the remaining life of the TransferredLegacy GOM Assets.
On August 3, 2020, Fieldwood again filed for protection under Chapter 11 of the U.S. Bankruptcy Code. Fieldwood has submitted aOn June 25, 2021, the United States Bankruptcy Court for the Southern District of Texas (Houston Division) entered an order confirming Fieldwood’s bankruptcy plan.

Pursuant to the Company has been engaged in discussions with Fieldwood and other interested parties regarding such plan. If approved byplan, the bankruptcy court, the submitted plan would separate the TransferredLegacy GOM Assets were separated into a standalone company, andwhich was subsequently merged into GOM Shelf.

By letter dated April 5, 2022, replacing two prior letters dated September 8, 2021 and February 22, 2022, and by subsequent letter dated March 1, 2023, GOM Shelf notified the Bureau of Safety and Environmental Enforcement (BSEE) that it was unable to fund the decommissioning obligations that it is currently obligated to perform on certain of the Legacy GOM Assets. As a result, Apache and other current and former owners in these assets have received orders from BSEE to decommission certain of the Legacy GOM Assets included in GOM Shelf’s notifications to BSEE. Apache expects to receive similar orders on the other Legacy GOM Assets included in GOM Shelf’s notification letters. Apache has also received orders to decommission other Legacy GOM Assets that were not included in GOM Shelf’s notification letters. Further, Apache anticipates that GOM Shelf may send additional such AROs, then Apache expectsnotices to BSEE in the future and that it may be required by the relevant governmental authoritiesreceive additional orders from BSEE requiring it to perform such AROs,decommission other Legacy GOM Assets.
As of December 31, 2023, Apache has incurred $819 million in which casedecommissioning costs related to Legacy GOM Assets. GOM Shelf did not, and has confirmed that it will applynot, reimburse Apache for these decommissioning costs. As a result, Apache has sought and will continue to seek reimbursement from its security for these costs. As of December 31, 2023, $293 million has been reimbursed from Trust A and $336 million has been reimbursed from the Letters of Credit. If GOM Shelf does not reimburse Apache for further decommissioning costs incurred with respect to Legacy GOM Assets, then Apache will continue to seek reimbursement from Trust A, to the extent of available funds, and thereafter, will seek reimbursement from the Bonds remainingand the Letters of Credit until all such funds and Trust A to pay for the AROs.securities are fully utilized. In addition, after such sources have been exhausted, Apache has agreed to provide a standby loan to GOM Shelf of up to $400 million for the new company to perform decommissioning (Standby Loan Agreement), with such standby loan secured by a first and prior lien on the TransferredLegacy GOM Assets.
If the foregoingcombination of GOM Shelf’s net cash flow from its producing properties, the Trust A funds, the Bonds, and the remaining Letters of Credit are insufficient to fully fund decommissioning of any Legacy GOM Assets that Apache may be required to perform or fund, or if GOM Shelf’s net cash flow from its remaining producing properties after the Trust A funds, Bonds, and Letters of Credit are exhausted is insufficient to repay any loans made by Apache under the CompanyStandby Loan Agreement, then Apache may be forced to use its available cash to coverfund the deficit.
As of December 31, 2023, Apache estimates that its potential liability to fund the remaining decommissioning of Legacy GOM Assets it may be ordered to perform or fund ranges from $824 million to $1.2 billion on an undiscounted basis. Management does not believe any additionalspecific estimate within this range is a better estimate than any other. Accordingly, the Company has recorded a contingent liability of $824 million as of December 31, 2023, representing the estimated costs of decommissioning it incursmay be required to perform or fund on Legacy GOM Assets. Of the total liability recorded, $764 million is reflected under the caption “Decommissioning contingency for performing such AROs.sold Gulf of Mexico properties,” and $60 million is reflected under “Other current liabilities” in the Company’s consolidated balance sheet. Changes in significant assumptions impacting Apache’s estimated liability, including expected decommissioning rig spread rates, lift boat rates, and planned abandonment logistics could result in a liability in excess of the amount accrued.
As of December 31, 2023, the Company has also recorded a $199 million asset, which represents the remaining amount the Company expects to be reimbursed from the Trust A funds, the Bonds, and the Letters of Credit for decommissioning it may be required to perform on Legacy GOM Assets. Of the total asset recorded, $21 million is reflected under the caption “Decommissioning security for sold Gulf of Mexico properties,” and $178 million is reflected under “Other current assets.”
The Company recognized $212 million, $157 million, and $446 million during 2023, 2022, and 2021, respectively, of “Losses on previously sold Gulf of Mexico properties” to reflect the net impact of changes to the estimated decommissioning liability and decommissioning asset to the Company’s statement of consolidated operations.
On June 21, 2023, the two sureties that issued bonds directly to Apache and two sureties that issued bonds to the issuing bank on the Letters of Credit filed suit against Apache in a case styled Zurich American Insurance Company, HCC International Insurance Company PLC, Philadelphia Indemnity Insurance Company and Everest Reinsurance Company (Insurers) v. Apache Corporation, Cause No. 2023-38238 in the 281st Judicial District Court, Harris County Texas. Insurers are seeking to prevent Apache from drawing on the Bonds and Letters of Credit and further allege that they are discharged from their reimbursement obligations related to decommissioning costs and are entitled to other relief. On July 20, 2023, the 281st Judicial District Court denied the Insurers’ request for a temporary injunction. On July 26, 2023, Apache removed the suit to the United States Bankruptcy Court for the Southern District of Texas (Houston Division) which subsequently held that the sureties’ state court lawsuit violated the terms of the Bankruptcy Confirmation Order and is void. Apache has drawn down the entirety of the Letters of Credit and is vigorously pursuing its claims against the sureties.

Insurance Program
ApacheThe Company maintains insurance policies that include coverage for physical damage to its assets, general liabilities, workers’ compensation, employers’ liability, sudden and accidental pollution, and other risks. The Company’s insurance coverage is subject to deductibles or retentions that it must satisfy prior to recovering on insurance. Additionally, the Company’s insurance is subject to policy exclusions and limitations. There is no assurance that insurance will adequately protect Apachethe Company against liability from all potential consequences and damages. Further, the Company does not have coverage in place for a variety of other risks including Gulf of Mexico named windstorm and business interruption.
51


Current insurance policies covering physical damage to the Company’s assets provide up to $1 billion in coverage per occurrence. These policies also provide sudden and accidental pollution coverage. The Company’s current insurance policies covering general liabilities provide $500 million in coverage, scaled to Apache’s interest. Service agreements, including drilling contracts, generally indemnify Apachethe Company for injuries and death of the service provider’s employees as well as subcontractors hired by the service provider.
ApacheThe Company purchases multi-year political risk insurance from U.S. InternationalThe Islamic Corporation for the Insurance of Investment and Export Credit Trade (ICIEC, an agency of the Islamic Development Finance Corporation (DFC), successor to Overseas Private Investment Corporation (OPIC),Bank) and highly-rated insurers covering a portion of its investments in Egypt for losses arising from confiscation, nationalization, and expropriation risks. The Islamic Corporation for the Insurance of Investment and Export Credit (ICIEC, an agency of the Islamic Development Bank) reinsures DFC. In the aggregate, these insurance policies provide up to $750 million of coverage, subject to policy terms and conditions and a retention of approximately $500 million.
ApacheThe Company also has an additional insurance policy with DFC,U.S. International Development Finance Corporation (DFC), which, subject to policy terms and conditions, provides up to $300$150 million of coverage through 2024 for losses arising from (1) non-payment by EGPC of arbitral awards covering amounts owed Apachethe Company on past due invoices and (2) expropriation of exportable petroleum in the event that actions taken by the government of Egypt prevent Apachethe Company from exporting ourits share of production. The Multilateral Investment Guarantee Agency (MIGA), a member of the World Bank Group, provides $150$60 million in reinsurance to DFC.
Future insurance coverage for the Company’s industry could increase in cost and may include higher deductibles or retentions. In addition, some forms of insurance may become unavailable or unavailable on terms economically acceptable.
Critical Accounting Estimates
ApacheThe Company prepares its financial statements and the accompanying notes in conformity with accounting principles generally accepted in the United States of America,U.S., which require management to make estimates and assumptions about future events that affect the reported amounts in the financial statements and the accompanying notes. ApacheThe Company identifies certain accounting policies involving estimation as critical accounting estimates based on, among other things, their impact on the portrayal of Apache’sthe Company’s financial condition, results of operations, or liquidity, andas well as the degree of difficulty, subjectivity, and complexity in their deployment. Critical accounting estimates coveraddress accounting matters that are inherently uncertain because thedue to unknown future resolution of such matters is unknown.matters. Management routinely discusses the development, selection, and disclosure of each of the Company’s critical accounting estimates.estimate. The following is a discussion of Apache’sthe Company’s most critical accounting estimates.
Reserves Estimates
Proved oil and gas reserves are the estimated quantities of natural gas, crude oil, condensate, and NGLs that geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing conditions, operating conditions, and government regulations.
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 recompletion. 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 reserves only if a development plan has been adopted indicating that they are scheduled to be drilled within five years, unless specific circumstances justify a longer time.
Despite the inherent imprecisionjudgment involved in these engineering estimates, the Company’s reserves are used throughout its financial statements. For example, since the Company uses the units-of-production method to amortize its oil and gas properties, the quantity of reserves could significantly impact DD&A expense. A material adverse change in the estimated volumes of reserves could result in property impairments. Finally, these reserves are the basis for Apache’sthe Company’s supplemental oil and gas disclosures. For more information regarding Apache’sthe Company’s supplemental oil and gas disclosures, Referrefer to Note 18Supplemental19—Supplemental Oil and Gas Disclosures (Unaudited) (Unaudited) in the Notes to Consolidated Financial Statements set forth in Part IV, Item 15 of this Annual Report on Form 10-K.
Reserves are calculated using an unweighted arithmetic average of commodity prices in effect on the first day of each of the previous 12twelve months, held flat for the life of the production, except where prices are defined by contractual arrangements. Operating costs, production and ad valorem taxes and future development costs are based on current costs with no escalation.
ApacheThe Company has elected not to disclose probable and possible reserves or reserve estimates in this filing.

Oil and Gas Exploration Costs
ApacheThe Company accounts for its exploration and production activities using the successful efforts method of accounting. Costs of acquiring unproved and proved oil and gas leasehold acreage are capitalized. Costs of drilling and equipping productive wells, including development dry holes, and related production facilities are also capitalized. Oil and gas exploration costs, other than the costs of drilling exploratory wells, are charged to expense as incurred. Costs associated with drilling an exploratory well are initially capitalized, or suspended, pending a determination as to whether proved reserves have been found. On a quarterly basis, management reviews the status of all suspended exploratory well costs in light of ongoing exploration activities and determines whether the Company is making sufficient progress in its ongoing exploration and appraisal efforts or, in the case of discoveries requiring government sanctioning, whether development negotiations are underway and proceeding as planned. If management determines that future appraisal drilling or development activities are unlikely to occur, associated suspended exploratory well costs are recorded as dry hole expense and reported in exploration expense in the statement of consolidated operations. Otherwise, the costs of exploratory wells remain capitalized.
Long-Lived Asset ImpairmentsOffshore Decommissioning Contingency
Long-lived assets used in operations, including proved oil and gas properties and GPT assets, are assessed for impairment whenever changes in facts and circumstances indicate a possible significant deterioration in future cash flows expected to be generated by an asset. Individual assets are grouped for impairment purposes based on a judgmental assessment of the lowest level for which there are identifiable cash flows that are largely independent of the cash flows of other groups of assets. If there is an indication that the carrying amount of an asset group may not be recovered, the asset is assessed by management through an established process in which changes to significant assumptions such as prices, volumes, and future development plans are reviewed. If, upon review, the sum of the undiscounted pre-tax cash flows is less than the carrying value of the asset group, the carrying value is written down to estimated fair value. Because there usually is a lack of quoted market prices for long-lived assets, the fair value of impaired assets is assessed by management using the income approach.
Under the income approach, the fair value of each asset group is estimated based on the present value of expected future cash flows. The income approach is dependent on a number of factors including estimates of forecasted revenue and operating costs, proved reserves, the success of future exploration for and development of unproved reserves, expected throughput volumes for GPT assets, discount rates, and other variables. Key assumptions used in developing a discounted cash flow model described above include estimated quantities of crude oil and natural gas reserves; estimates of market prices considering forward commodity price curves as of the measurement date; and estimates of operating, administrative, and capital costs adjusted for inflation. The Company discounts the resultinghas potential exposure to future cash flows using a discount rate believedobligations related to be consistent with those applied by market participants.
To assess the reasonableness of our fair value estimate, when available management uses a market approachdivested properties. For information regarding estimated potential decommissioning obligations on sold properties, please refer to compare the fair value to similar assets. This requires management to make certain judgments about the selection of comparable assets, recent comparable asset transactions,“Potential Decommissioning Obligations on Sold Properties” above and transaction premiums.
Although the fair value estimate of each asset group is based on assumptions believed to be reasonable, those assumptions are inherently unpredictable and uncertain, and actual results could differ from the estimate. Negative revisions of estimated reserves quantities, increases in future cost estimates, divestiture of a significant component of the asset group, or sustained decreases in crude oil or natural gas prices could lead to a reduction in expected future cash flows and possibly an additional impairment of long-lived assets in future periods.
Over the past several years, the Company has experienced substantial volatility in commodity prices, which impacted its future development plans and operating cash flows. As such, material impairments of certain proved oil and gas properties and gathering, processing, and transmission facilities were recorded in 2020, 2019, and 2018. For discussion of these impairments, see “Fair Value Measurements” of Note 1—Summary of Significant Accounting Policies12—Commitments and Contingencies in the Notes to Consolidated Financial Statements.Statements in Part IV, Item 5 of this Annual Report on Form 10-K.
The Company’s estimated contingent obligation is primarily associated with the abandonment, removal and decommissioning of offshore wells and platforms in the Gulf of Mexico. Estimating any future obligation requires significant judgment. The Company utilizes actual abandonment and decommissioning costs incurred as the basis to estimate the expected cash outflows for future obligations. Actual costs incurred often vary based on each structure’s condition, depth-of-water, type, and other similar factors, which are key considerations when estimating the remaining well and platform decommissioning obligation. Asset removal technologies and costs are constantly changing, as are regulatory, political, environmental, and safety considerations. Changes in significant assumptions or the regulatory framework impacting the Company’s estimated liability could result in a liability in excess of the amount accrued.
Asset Retirement Obligation (ARO)
The Company has significant obligations to remove tangible equipment and restore land or seabed at the end of oil and gas production operations. Apache’sThe Company’s removal and restoration obligations are primarily associated with plugging and abandoning wells and removing and disposing of offshore oil and gas platforms in the North Sea and Gulf of Mexico.Sea. Estimating the future restoration and removal costs is difficult and requires management to make estimates and judgments. Asset removal technologies and costs are constantly changing, as are regulatory, political, environmental, safety, and public relations considerations.
53


ARO associated with retiring tangible long-lived assets is recognized as a liability in the period in which the legal obligation is incurred and becomes determinable. The liability is offset by a corresponding increase in the underlying asset. The ARO liability reflects the estimated present value of the amount of dismantlement, removal, site reclamation, and similar activities associated with Apache’sthe Company’s oil and gas properties and other long-lived assets. The Company utilizes current retirement costs to estimate the expected cash outflows for retirement obligations. Inherent in the present value calculation are numerous assumptions and judgments including the ultimate settlement amounts, inflation factors, credit-adjusted discount rates, timing of settlement, and changes in the legal, regulatory, environmental, and political environments. Accretion expense is recognized over time as the discounted liability is accreted to its expected settlement value.
Income Taxes
The Company’s oil and gas exploration and production operations are subject to taxation on income in numerous jurisdictions worldwide. The Company records deferred tax assets and liabilities to account for the expected future tax consequences of events that have been recognized in its financial statements and tax returns. Management routinely assesses the ability to realize the Company’s deferred tax assets. If management concludes that it is more likely than not that some portion or all of the deferred tax assets will not be realized under accounting standards, the tax asset would be reduced by a valuation allowance. Numerous judgments and assumptions are inherent in the determination of future taxable income, including factors such as future operating conditions (particularly as related to prevailing oil and gas prices).
The Company regularly assesses and, if required, establishes accruals for uncertain tax positions that could result from assessments of additional tax by taxing jurisdictions in countries where the Company operates. The Company recognizes a tax benefit from an uncertain tax position when it is more likely than not that the position will be sustained upon examination, based on the technical merits of the position. These accruals for uncertain tax positions are subject to a significant amount of judgment and are reviewed and adjusted on a periodic basis in light of changing facts and circumstances considering the progress of ongoing tax audits, case law, and any new legislation. The Company believes that its accruals for uncertain tax positions are adequate in relation to the potential for any additional tax assessments.

ITEM 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
The primary objective of the following information is to provide forward-looking quantitative and qualitative information about ourthe Company’s exposure to market risk. The term market risk relates to the risk of loss arising from adverse changes in oil, gas, and NGL prices, interest rates, or foreign currency and adverse governmental actions. The disclosures are not meant to be precise indicators of expected future losses, but rather indicators of reasonably possible losses. The forward-looking information provides indicators of how we viewthe Company views and manage ourmanages its ongoing market risk exposures.
Commodity Price Risk
The Company’s revenues, earnings, cash flow, capital investments and, ultimately, future rate of growth are highly dependent on the prices the Company receives for its crude oil, natural gas, and NGLs, which have historically been very volatile because of unpredictable events such as economic growth or retraction, weather, political climate, and global supply and demand. These factors have only been heightened as the result of continuing negative demand implications of the COVID-19 pandemic. The Company continually monitors its market risk exposure, including the impactas oil and developments related to the COVID-19 pandemic, which introduced significant volatilitygas supply and demand are impacted by uncertainties in the commodity and financial markets subsequent toassociated with the year ended December 31, 2019.conflict in Ukraine, the recent conflict in Israel and Gaza, actions taken by foreign oil and gas producing nations, including OPEC+, global inflation, and other current events.
The Company’s average crude oil price realizations decreased 3419 percent to $39.60$80.83 per barrel in 20202023 from $60.05$99.39 per barrel in 2019.2022. The Company’s average natural gas price realizations decreased 440 percent to $1.83$2.96 per Mcf in 20202023 from $1.90$4.97 per Mcf in 2019.2022. The Company’s average NGL price realizations decreased 2538 percent to $11.84$21.48 per barrel in 20202023 from $15.74$34.62 per barrel in 2019.2022. Based on average daily production for 2020,2023, a $1.00 per barrel change in the weighted average realized oil price would have increased or decreased revenues for the year by approximately $78$71 million, a $0.10 per Mcf change in the weighted average realized price of natural gas price would have increased or decreased revenues for the year by approximately $33$29 million, and a $1.00 per barrel change in the weighted average realized NGL price would have increased or decreased revenues for the year by approximately $28$21 million.
54


Apache periodically enters into derivative positions on a portion of its projected oil and natural gas production through a variety of financial and physical arrangements intended to manage fluctuations in cash flows resulting from changes in commodity prices. Such derivative positions may include the use of futures contracts, swaps, and/or options. Apache does not hold or issue derivative instruments for trading purposes. As of December 31, 2020, the Company had open natural gas derivatives not designated as cash flow hedges in an asset position with a fair value of $11 million. The impact of a 10 percent movement in natural gas prices would be immaterial to the fair value of the commodity derivatives. These fair value changes assume volatility based on prevailing market parameters at December 31, 2020. See Note 4—Derivative Instruments and Hedging Activities in the Notes to Consolidated Financial Statements set forth in Part IV, Item 15 of this Annual Report Form 10-K for notional volumes and terms with the Company’s derivative contracts.
Interest Rate Risk
At December 31, 2020,2023, Apache had approximately $8.1$4.8 billion, net, carrying value ofin outstanding notes and debentures, outstanding, all of which was fixed-rate debt, with a weighted average interest rate of 4.985.34 percent. Although near-term changes in interest rates may affect the fair value of Apache’s fixed-rate debt, theysuch changes do not expose the Company to the risk of earnings or cash flow loss associated with that debt. Apache
The Company is also exposed to interest rate risk related to its interest-bearing cash and cash equivalents balances and amounts outstanding under its commercial paper program andsyndicated credit facilities. As of December 31, 2020,2023, the Company’sCompany had approximately $84 million in cash and cash equivalents, totaled approximately $262 million, approximately 4688 percent of which was invested in money market funds and short-term investments with major financial institutions. As of December 31, 2020, the Company2023, Apache had no borrowings outstanding under APA’s syndicated revolving credit facility borrowings of $150 million and $624 million under its Apache and Altus credit facilities, respectively. A changefacilities. Changes in the interest rate applicable to the Company’s short-term investments and credit facility borrowings wouldare expected to have an immaterial impact on earnings and cash flows but could impact interest costs associated with future debt issuances or any future borrowings under its commercial paper program, revolving credit facilities, and money market lines of credit.borrowings.
Foreign Currency Exchange Rate Risk
The Company’s cash activities relating to certain international operations is based on the U.S. dollar equivalent of cash flows measured in foreign currencies. The Company’s North Sea production is sold under U.S. dollar contracts, andwhile the majority of costs incurred are paid in British pounds. InThe Company’s Egypt substantially all oil and gas production is sold under U.S. dollar contracts, and the majority of the costs incurred are denominated in U.S. dollars. Transactions denominated in British pounds are converted to U.S. dollar equivalents based on the average exchange rates during the period. The Company monitors foreign currency exchange rates of countries in which it is conducting business and may, from time to time, implement measures to protect against foreign currency exchange rate risk.
Foreign currency gains and losses also arise when monetary assets and monetary liabilities denominated in foreign currencies are translated at the end of each month. CurrencyForeign currency gains and losses are included as either a component of “Other” under “Revenues and Other” or, as is the case when the Company re-measures its foreign tax liabilities, as a component of the Company’s provision for income tax expense on the statement of consolidated operations. A foreignForeign currency net gain or loss of $5$3 million would result from a 10 percent weakening or strengthening, respectively, in the British pound as of December 31, 2020.
The Company is subject to increased foreign currency risk associated with the effects of the U.K.’s withdrawal from the European Union. Apache has periodically entered into foreign exchange contracts in order to minimize the impact of fluctuating exchange rates for the British pound on the Company’s operating expenses. The Company had no outstanding foreign exchange derivative contracts as of December 31, 2020.2023.

REPORT OF MANAGEMENT ON INTERNAL CONTROL OVER FINANCIAL REPORTING
Management of the Company is responsible for the preparation and integrity of the consolidated financial statements appearing in this annual report on Form 10-K. The financial statements were prepared in conformity with accounting principles generally accepted in the United States and include amounts that are based on management’s best estimates and judgments.
Management of the Company is responsible for establishing and maintaining effective internal control over financial reporting as such term is defined in Rule 13a-15(f) under the Securities Exchange Act of 1934. The Company’s internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the consolidated financial statements. Our internal control over financial reporting is supported by a program of internal audits and appropriate reviews by management, written policies and guidelines, careful selection and training of qualified personnel and a written code of business conduct adopted by our Company’s board of directors, applicable to all Company directors and all officers and employees of our Company and subsidiaries.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements and even when determined to be effective, can only provide reasonable assurance with respect to financial statement preparation and presentation. 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.
Management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2020.2023. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control – Integrated Framework (2013). Based on our assessment, management believes that the Company maintained effective internal control over financial reporting as of December 31, 2020.2023.
The Company’s independent auditors, Ernst & Young LLP, a registered public accounting firm, are appointed by the Audit Committee of the Company’s board of directors. Ernst & Young LLP have audited and reported on the consolidated financial statements of Apache Corporation and subsidiaries and the effectiveness of the Company’s internal control over financial reporting. The reports of the independent auditors follow this report on pages F-2 and F-3.F-4.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the ShareholdersShareholder and the Board of Directors of Apache Corporation:Corporation
Opinion on Internal Control Over Financial Reporting
We have audited Apache Corporation and subsidiaries’ 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, Apache Corporation and subsidiaries (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2020, based on the COSO criteria.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2020 and 2019, the related statements of consolidated operations, comprehensive income (loss), cash flows and changes in equity and noncontrolling interest for each of the three years in the period ended December 31, 2020, and the related notes and our report dated February 25, 2021 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 Report of Management 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.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Shareholders and the Board of Directors of Apache Corporation:
Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheets of Apache Corporation and subsidiaries (the Company) as of December 31, 20202023 and 2019,2022, the related statements of consolidated operations, comprehensive income (loss), cash flows and changes in equity (deficit) and noncontrolling interest for each of the three years in the period ended December 31, 2020,2023, 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, 20202023 and 2019,2022, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2020,2023, 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 February 25, 2021 expressed an unqualified 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 PCAOBPublic Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.
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.

Depreciation, depletion and amortization and impairment of property and equipment

Description of
the Matter
At December 31, 2020,2023, the carrying value of the Company’s property and equipment was $8,819$8,724 million, and depreciation, depletion and amortization (DD&A) expense was $1,772 million, and impairment expense was $4,501$1,399 million for the year then ended. As described in Note 1, the Company follows the successful efforts method of accounting for its oil and gas properties. DD&A of the cost of proved oil and gas properties is calculated using the unit-of-production method based on proved oil and gas reserves, as estimated by the Company’s internal reservoir engineers. When circumstances indicate that the carrying value of property and equipment may not be recoverable, the Company compares unamortized capitalized costs to the expected undiscounted pre-tax future cash flows for the associated assets. If the expected undiscounted pre-tax future cash flows are lower than the unamortized capitalized cost, the capitalized cost is reduced to fair value.


F-2


Proved oil and gas reserves are those quantities of natural gas, crude oil, condensate, and natural gas liquids, which by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible from a given date forward, from known reservoirs, and under existing economic conditions, operating methods, and government regulations. Additionally, the expected future cash flows used for impairment reviews and related fair value calculations are based on judgmental assessments of future production volumes from estimated oil and gas reserves. Significant judgmentJudgment is required by the Company’s internal reservoir engineers in evaluating geological and engineering data used when estimating oil and gas reserves. Estimating reserves also requires the selection of inputs, including oil and gas price assumptions, future operating and capital costs assumptions, and tax rates by jurisdiction, among others. Because of the complexity involved in estimating oil and gas reserves, management engaged independent petroleum engineers to audit the proved oil and gas reserve estimates prepared by the Company’s internal reservoir engineers for select properties as of December 31, 2020.2023.
Auditing the Company’s DD&A and impairment calculations is complex because of the use of the work of the internal reservoir engineers and the independent petroleum engineers and the evaluation of management’s determination of the inputs described above used by the engineers in estimating oil and gas reserves.
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, and impairment, including management’s controls over the completeness and accuracy of the financial data provided to the engineers for use in estimating oil and gas reserves.


Our audit procedures included, among others, evaluating the professional qualifications and objectivity of the Company’s internal reservoir engineers primarily responsible for overseeing the preparation of the reserve estimates and the independent petroleum engineers used to audit the proved oil and gas reserve estimates for select properties. 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 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 the SEC rule that undrilled locations are scheduled to be drilled within five years, unless specific circumstances justify a longer time, by assessing consistency of the development projections with the Company’s development plan and the availability of capital relative to the development plan. We also tested the mathematical accuracy of the DD&A and impairment calculations,calculation, including comparing the oil and gas reserve amounts used in the calculationscalculation to the Company’s reserve reports.

Accounting for asset retirement obligation for the North Sea segment
Description of
the Matter
At December 31, 2020,2023, the asset retirement obligation (ARO) balance totaled $1,944$2,430 million. As further described in Note 8,9, the Company’s ARO reflects the estimated present value of the amount of dismantlement, removal, site reclamation, and similar activities associated with the Company’s oil and gas properties and other long-lived assets. The estimation of the ARO related to the North Sea segment requires significant judgment given the magnitude of the expected retirement costs and higher estimation uncertainty related to the timing of settlements and settlement amounts.costs.
Auditing the Company’s ARO for the North Sea segment is complex and highly judgmental because of the significant estimation required by management in determining the obligation. In particular, the estimate was sensitive to significant subjective assumptions such as retirement cost estimates, and the estimated timing of settlements, which are both affected by expectations about future market and economic conditions.



F-3


How We
Addressed the
Matter in Our
Audit
We obtained an understanding, evaluated the design, and tested the operating effectiveness of the Company’s internal controls over its ARO estimation process, including management’s review of the significant assumptions that have a material effect on the determination of the obligations. We also tested management’s controls over the completeness and accuracy of financial data used in the valuation.
To test the ARO for the North Sea segment, our audit procedures included, among others, assessing the significant assumptions and inputs used in the valuation, such as retirement cost estimates and timing of settlement assumptions.estimates. For example, we evaluated retirement cost estimates by comparing the Company’s estimates to recent offshore activities and costs. Additionally,We also involved our internal specialists in testing the underlying retirement cost estimates.
Accounting for decommissioning contingency for sold Gulf of Mexico properties
Description of
the Matter
At December 31, 2023, the decommissioning contingency for sold Gulf of Mexico properties (decommissioning contingency) balance totaled $824 million. As further described in Note 12, the Company’s decommissioning contingency reflects the estimated undiscounted potential liability to fund decommissioning of the sold Gulf of Mexico properties. The estimation of the decommissioning contingency requires significant judgment given the magnitude and higher estimation uncertainty of the expected retirement costs.

Auditing the Company’s decommissioning contingency is complex and highly judgmental because of the significant estimation required by management in determining the decommissioning contingency. In particular, the estimate was sensitive to retirement cost estimates, which are subjective assumptions affected by expectations about future market and economic conditions.
How We
Addressed the
Matter in Our
Audit
We obtained an understanding, evaluated the design, and tested the operating effectiveness of the Company’s internal controls over its decommissioning contingency estimation process, including management’s review of the significant assumptions that have a material effect on the determination of the contingency. We also tested management’s controls over the completeness and accuracy of financial data used in the valuation.

To test the decommissioning contingency, our audit procedures included, among others, assessing the significant assumptions and inputs used in the valuation, such as retirement cost estimates.

1.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Accounting policies used by Apache and its subsidiaries reflect industry practices and conform to accounting principles generally accepted in the U.S. (GAAP). The Company’s financial statements for prior periods may include reclassifications that were made to conform to the current-year presentation. Significant accounting policies are discussed below.
Principles of Consolidation
The accompanying consolidated financial statements include the accounts of Apache and its subsidiaries after elimination of intercompany balances and transactions. Apache’s consolidated financial statements reflect the impacts of the Holding Company Reorganization on a prospective basis, and results prior to completion of the Holding Company Reorganization have not been restated. Refer to Note 2—Transactions with Parent Affiliate for more detail.
The Company’s undivided interests in oil and gas exploration and production ventures and partnerships are proportionately consolidated.
The Company consolidates all other investments in which, either through direct or indirect ownership, it has more than a 50 percent voting interest or controls the financial and operating decisions. Noncontrolling interests represent third-partyoutside ownership in the net assets of a consolidated subsidiary of Apache and are reflected separately in the Company’s financial statements.
In conjunction with the ratification of a merged concession agreement with the Egyptian General Petroleum Corporation (EGPC) in December 2021, Apache modified partnership agreements for certain consolidated subsidiaries. Apache subsequently determined that one of its limited partnership subsidiaries, which has control over Apache’s Egyptian operations, qualified as a variable interest entity (VIE) under GAAP. Apache continues to consolidate this limited partnership subsidiary because the Company has concluded that it has a controlling financial interest in the Egyptian operations and was determined to be the primary beneficiary of the VIE. For all periods presented, Sinopec International Petroleum Exploration and Production Corporation (Sinopec) ownshas owned a one-third minority participation in Apache’sthe Company’s consolidated Egypt oil and gas business as a noncontrolling interest. Under the modified partnership agreements, APA owns a noncontrolling interest which isparticipation in the remaining two-thirds of its consolidated Egypt oil and gas business. Refer to Note 2—Transactions with Parent Affiliate for detail regarding APA’s noncontrolling interest. All noncontrolling interests are reflected as a separate component of equity in the Company’s consolidated balance sheet.
Additionally, prior to the BCP Business Combination (as defined below), third-party investors ownowned a minority interest of approximately 21 percent of Altus, Midstream Company (ALTM), which iswas reflected as a separate noncontrolling interest component of equity in Apache’sthe Company’s consolidated balance sheet. ALTM qualifiesqualified as a variable interest entity (VIE)VIE under GAAP.GAAP, which Apache consolidates the activitiesconsolidated because a wholly owned subsidiary of ALTM because it has concluded that it hasApache had a controlling financial interest in ALTM and iswas determined to be the primary beneficiary of the VIE. On June 12, 2019, Altus Midstream LP issued and sold Series A Cumulative Redeemable Preferred Units (the Preferred Units) through a private offering that admitted additional limited partners with separate rights for the Preferred Unit holders. Refer to Note 13—Redeemable Noncontrolling Interest - Altus for further detail.
Investments in which the Company holds less than 50 percent of the voting interest are typically accounted for under the equity method of accounting, with the balance recorded separately as “Equity method interests” in the Company’s consolidated balance sheet and as a component of “Other” under “Revenues and Other” in the Company’s statement of consolidated operations.

On February 22, 2022, ALTM closed a transaction to combine with privately owned BCP Raptor Holdco LP (BCP and, together with BCP Raptor Holdco GP, LLC, the Contributed Entities) in an all-stock transaction, pursuant to the Contribution Agreement entered into by and among ALTM, Altus Midstream LP, New BCP Raptor Holdco, LLC (the Contributor), and BCP (the BCP Contribution Agreement). Pursuant to the BCP Contribution Agreement, the Contributor contributed all of the equity interests of the Contributed Entities (the Contributed Interests) to Altus Midstream LP, with each Contributed Entity becoming a wholly owned subsidiary of Altus Midstream LP (the BCP Business Combination). Upon closing the transaction, the combined entity was renamed Kinetik Holdings Inc. (Kinetik), and the Company determined that it was no longer the primary beneficiary of Kinetik. The Company further determined that Kinetik no longer qualified as a VIE under GAAP.As a result, the Company deconsolidated ALTM on February 22, 2022. Refer to Note 3—Acquisitions and Divestitures for further detail.
During each of the years ended December 31, 2023 and 2022, the Company had a designated director on the Kinetik board of directors. As a result, the Company is considered to have had significant influence over Kinetik for all periods presented and will continue to have such influence until such time as Kinetik appoints a replacement for the Company’s designated director, given that the Company’s current beneficial ownership percentage in Kinetik no longer entitles it to designate a director to the Kinetik board.
Investments in which the Company has significant influence, but not control, are accounted for under the equity method of accounting. These investments are recorded separately as “Equity method interests” in the Company’s consolidated balance sheet. The Company elected the fair value option to account for its equity method interest in Kinetik. Refer to Note 7—Equity Method Interests for further detail.
Use of Estimates
Preparation of financial statements in conformity with GAAP and disclosure of contingent assets and liabilities requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The Company bases its estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about carrying values of assets and liabilities that are not readily apparent from other sources. The Company evaluates its estimates and assumptions on a regular basis. Actual results may differ from these estimates and assumptions used in preparation of the Company’s financial statements, and changes in these estimates are recorded when known.
Significant estimates with regard to these financial statements include the estimates of fair value for long-lived assets (see(refer to “Fair Value Measurements” and “Property and Equipment” sections in this Note 1 below), the fair value determination of acquired assets and liabilities (see(refer to Note 2—3—Acquisitions and Divestitures), the fair value of equity method interests (refer to “Equity Method Interests” within this Note 1 and Note 7—Equity Method Interests), the assessment of asset retirement obligations (see(refer to Note 8—9—Asset Retirement Obligation), the estimate of income taxes (see(refer to Note 10—11—Income Taxes), the estimation of the contingent liability representing Apache’s potential decommissioning obligations on sold properties in the Gulf of Mexico (refer to Note 12—Commitments and Contingencies), and the estimate of proved oil and gas reserves and related present value estimates of future net cash flows therefrom (see(refer to Note 18—19—Supplemental Oil and Gas Disclosures (Unaudited)).
Fair Value Measurements
Certain assets and liabilities are reported at fair value on a recurring basis in Apache’sthe Company’s consolidated balance sheet. Accounting Standards Codification (ASC) 820-10-35, “Fair Value Measurement” (ASC 820), provides a hierarchy that prioritizes and defines the types of inputs used to measure fair value. The fair value hierarchy gives the highest priority to Level 1 inputs, which consist of unadjusted quoted prices for identical instruments in active markets. Level 2 inputs consist of quoted prices for similar instruments. Level 3 valuations are derived from inputs that are significant and unobservable; hence, these valuations have the lowest priority.
The valuation techniques that may be used to measure fair value include a market approach, an income approach, and a cost approach. A market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities. An income approach uses valuation techniques to convert future amounts to a single present amount based on current market expectations, including present value techniques, option-pricing models, and the excess earnings method. The cost approach is based on the amount that currently would be required to replace the service capacity of an asset (replacement cost).

Refer to “Equity Method Interests” within this Note 1 below and Note 3—Acquisitions and Divestitures for further detail on the BCP Business Combination.
Revenue Recognition
Upstream
The Company’s upstream oil and gas segments primarily generate revenue from contracts with customers from the sale of its crude oil, natural gas, and natural gas liquids production volumes. In addition to Apache-related production volumes, the Company also sells commodity volumes purchased from third parties to provide flexibility to fulfill sales obligations and commitments. Under these commodity sales contracts, the physical delivery of each unit of quantity represents a single, distinct performance obligation on behalf of the Company. Contract prices are determined based on market-indexed prices, adjusted for quality, transportation, and other market-reflective differentials. Revenue is measured by allocating an entirely variable market price to each performance obligation and recognized at a point in time when control is transferred to the customer. The Company considers a variety of facts and circumstances in assessing the point of control transfer, including but not limited to: whether the purchaser can direct the use of the hydrocarbons, the transfer of significant risks and rewards, and the Company’s right to payment. Control typically transfers to customers upon the physical delivery at specified locations within each contract and the transfer of title.
The Company’s Egypt operations are conducted pursuant to production-sharing contracts (PSCs). Under the terms of the Company’s PSCs, the Company is the contractor partner (Contractor) with the Egyptian General Petroleum Corporation (EGPC) and bears the risk and cost of exploration, development, and production activities. In return, if exploration is successful, the Contractor receives entitlement to variable physical volumes of hydrocarbons, representing recovery of the costs incurred and a stipulated share of production after cost recovery. Additionally, the Contractor’s income taxes, which remain the liability of the Contractor under domestic law, are paid by EGPC on behalf of the Contractor out of EGPC’s production entitlement. Income taxes paid to the Arab Republic of Egypt on behalf of the Contractor are recognized as oil and gas sales revenue and income tax expense and reflected as production and estimated reserves. Because Contractor cost recovery entitlement and income taxes paid on its behalf are determined as a monetary amount, the quantities of production entitlement and estimated reserves attributable to these monetary amounts will fluctuate with commodity prices. In addition, because the Contractor income taxes are paid by EGPC, the amount of the income tax has no economic impact on the Company’s Egypt operations despite impacting the Company’s production and reserves.
Refer to Note 18—Business Segment Information for a disaggregation of revenue by product and reporting segment.
Altus Midstream
Prior to the deconsolidation of Altus on February 22, 2022, the Company’s Altus Midstream segment was operated by ALTM, through its subsidiary, Altus Midstream LP. Altus generated revenue from contracts with customers from its gathering, compression, processing, and transmission services provided on the Company’s natural gas and natural gas liquid production volumes. Under these long-term commercial service contracts, providing the related service represented a single, distinct performance obligation on behalf of Altus that was satisfied over time. In accordance with the terms of these agreements, Altus primarily received a fixed fee for each contract year, subject to yearly fee escalation recalculations. Revenue was primarily measured using the output method and recognized in the amount to which Altus had the right to invoice, as performance completed to date corresponded directly with the value to its customers. For the periods prior to the BCP Business Combination, Altus Midstream segment revenues were primarily attributable to sales between Altus and APA, which were fully eliminated upon consolidation.

The2023 and 2022, respectively. Payments under all contracts with customers are typically due and received within a short-term period of one year or less, after physical delivery of the product or service has been rendered. Over the past year, the Company recorded proved property impairments totaling $3.9 billion, $354 million, and $7 millionexperienced a gradual decline in the U.S., Egypt, and North Sea, respectively, alltimeliness of which were impaired to their estimated fair values as a result of lower forecasted commodity prices, changes to planned development activity, and increasing market uncertainty. Impairments totaling $68 million were similarly recordedreceipts from the EGPC for GPT facilities in Egypt. These impairments are discussed in further detail below in “Property and Equipment - Oil and Gas Property” and “Property and Equipment - Gathering, Processing, and Transmission Facilities.”
The Company also performed an interim impairment analysis of the goodwill related to its Egypt reporting unit. Reductions in estimated net present value of expected future cash flows fromCompany’s Egyptian oil and gas properties resultedsales.

As a resultcould lead to further delays, deferrals of these assessments,payment, or non-payment in the future; however, the Company recognized non-cash impairmentscurrently anticipates that it will ultimately be able to collect its receivable from EGPC.
In accordance with the provisions of ASC 606, “Revenue from Contracts with Customers,” variable market prices for each short-term commodity sale are allocated entirely to each performance obligation as the terms of payment relate specifically to the Company’s efforts to satisfy its obligations. As such, the Company has elected the practical expedients available under the standard to not disclose the aggregate transaction price allocated to unsatisfied, or partially unsatisfied, performance obligations as of the entire amount of recorded goodwill in the Egypt reporting unit of $87 million in the first quarter of 2020.
During the remainder of 2020, the Company recorded additional proved property impairments totaling $20 million in Egypt, as well as $13 million for the early termination of drilling rig leases, $5 million for inventory revaluations, and $9 million of other asset impairments, all in the U.S.
During the fourth quarter of 2019, following a material reduction to planned investment in Apache’s Alpine High development, the Company recorded impairments totaling $1.4 billion for its Alpine High proved properties and upstream infrastructure which were written down to their fair values. Altus separately assessed its long-lived infrastructure assets for impairment based on expected reductions to future throughput volumes from Alpine High. Altus subsequently recorded impairments totaling $1.3 billion on its GPT facilities. These impairments are discussed in further detail below in “Property and Equipment - Oil and Gas Property” and “Property and Equipment - Gathering, Processing, and Transmission Facilities.”
Separate from the Company’s Alpine High and Altus impairments, Apache entered into agreements to sell certain of its assets in the western Anadarko Basin in Oklahoma and Texas. As a result of these agreements, a separate impairment analysis was performed for eachend of the assets within the disposal groups. The analyses were based on the agreed-upon proceeds less costs to sell for the transaction, a Level 1 fair value measurement. The carrying value of the net assets to be divested exceeded the fair value implied by the expected net proceeds, resulting in impairments in the second and fourth quarters of 2019 totaling $255 million, including $101 million on the Company’s proved properties, $149 million on its unproved properties, and $5 million on other working capital. For more information regarding this transaction, refer to Note 2—Acquisitions and Divestitures.reporting period.
For the year ended December 31, 2018, the Company recorded asset impairments totaling $511 million in connection with fair value assessments. Impairments totaling $328 million and $56 million were recorded for proved properties, and a gathering and processing facility in Oklahoma, respectively, which were written down to their fair values associated with U.S. assets to be divested. During the third quarter of 2018, Apache agreed to sell certain of its unproved properties offshore the U.K. in the North Sea. As a result, the Company performed a fair value assessment of the properties and recorded a $10 million impairment on the carrying values of the associated capitalized exploratory well costs. The fair value of the impaired assets was determined using the negotiated sales price, a Level 1 fair value measurement. Also in 2018, the Company recorded $113 million for the impairment of an equity method investment in the U.S. based on a negotiated sales price and $4 million for inventory write-downs in the U.S. for obsolescence.
Cash and Cash Equivalents
The Company considers all highly liquid short-term investments with a maturity of three months or less at the time of purchase to be cash equivalents. These investments are carried at cost, which approximates fair value. As of December 31, 20202023 and 2019,2022, the Company had $262$84 million and $247$185 million, respectively, of cash and cash equivalents, of which approximately $24 million and $6 million, respectively, was held by Altus.equivalents.

Accounts Receivable and Allowance for Credit Losses
Accounts receivable are stated at amortized cost net of an allowance for credit losses. The Company routinely assesses the collectability of its financial assets measured at amortized cost. In June 2016, the Financial Accounting Standards Board (FASB) issued ASU 2016-13, “Financial Instruments-Credit Losses.” The standard changes the impairment model for trade receivables, held-to-maturity debt securities, net investments in leases, loans, and other financial assets measured at amortized cost. This ASU requires the use of a new forward-looking “expected loss” model compared to the previous “incurred loss” model, resulting in accelerated recognition of credit losses. Apache adopted this update in the first quarter of 2020. This ASU primarily applies to the Company’s accounts receivable balances, of which the majority are received within a short-term period of one year or less. The Company monitors the credit quality of its counterparties through review of collections, credit ratings, and other analyses. The Company develops its estimated allowance for expected credit losses primarily using an aging method and analyses of historical loss rates as well as consideration of current and future conditions that could impact its counterparties’ credit quality and liquidity. The adoption and implementation of this ASU did not have a material impact on the Company’s financial statements.
The following table presents changes to the Company’s allowance for credit loss:

Inventories
Inventories consist principally of tubular goods and equipment and are stated at the lower of weighted-average cost or net realizable value. Oil produced but not sold, primarily in the North Sea, is also recorded to inventory and is stated at the lower of the cost to produce or net realizable value.
During 2023, the Company recorded $50 million of impairments in connection with valuations of drilling and operations equipment inventory upon the Company’s decision to suspend drilling operations in the North Sea.

The Company also recorded other impairments during 2021 of approximately $26 million in connection with inventory valuations in Egypt and $22 million in connection with inventory valuations and expected equipment dispositions in the North Sea.
Property and Equipment
The carrying value of the Company’s property and equipment represents the cost incurred to acquire the property and equipment, including capitalized interest, net of any impairments. For business combinations and acquisitions, property and equipment cost is based on the fair values at the acquisition date.
Oil and Gas Property
The Company follows the successful efforts method of accounting for its oil and gas property. Under this method of accounting, exploration costs, such as exploratory geological and geophysical costs, delay rentals, and exploration overhead, are expensed as incurred. All costs related to production, general corporate overhead, and similar activities are expensed as incurred. If an exploratory well provides evidence to justify potential development of reserves, drilling costs associated with the well are initially capitalized, or suspended, pending a determination as to whether a commercially sufficient quantity of proved reserves can be attributed to the area as a result of drilling. This determination may take longer than one year in certain areas depending on, among other things, the amount of hydrocarbons discovered, the outcome of planned geological and engineering studies, the need for additional appraisal drilling activities to determine whether the discovery is sufficient to support an economic development plan, and government sanctioning of development activities in certain international locations. At the end of each quarter, management reviews the status of all suspended exploratory well costs in light of ongoing exploration activities; in particular, whether the Company is making sufficient progress in its ongoing exploration and appraisal efforts or, in the case of discoveries requiring government sanctioning, whether development negotiations are underway and proceeding as planned. If management determines that future appraisal drilling or development activities are unlikely to occur, associated suspended exploratory well costs are expensed.

Acquisition costs of unproved properties are assessed for impairment at least annually and are transferred to proved oil and gas properties to the extent the costs are associated with successful exploration activities. Significant undeveloped leases are assessed individually for impairment based on the Company’s current exploration plans. Unproved oil and gas properties with individually insignificant lease acquisition costs are amortized on a group basis over the average lease term at rates that provide for full amortization of unsuccessful leases upon lease expiration or abandonment. Costs of expired or abandoned leases are charged to exploration expense, while costs of productive leases are transferred to proved oil and gas properties. Costs of maintaining and retaining unproved properties, as well as amortization of individually insignificant leases and impairment of unsuccessful leases, are included in exploration costs in the statement of consolidated operations.
The following table represents non-cash impairment charges of the carrying value of the Company’s unproved properties:

Costs to develop proved reserves, including the costs of all development wells and related equipment used in the production of crude oil and natural gas, are capitalized. Depreciation of the cost of proved oil and gas properties is calculated using the unit-of-production (UOP) method. The UOP calculation multiplies the percentage of estimated proved reserves produced each quarter by the carrying value of associated proved oil and gas properties. The reserve base used to calculate depreciation for leasehold acquisition costs and the cost to acquire proved properties is the sum of proved developed reserves and proved undeveloped reserves. The reserve base used to calculate the depreciation for capitalized well costs is the sum of proved developed reserves only. Estimated future dismantlement, restoration and abandonment costs, net of salvage values, are included in the depreciable cost.

Oil and gas properties are grouped for depreciation in accordance with ASC 932, “Extractive Activities—Oil and Gas.” The basis for grouping is a reasonable aggregation of properties with a common geological structural feature or stratigraphic condition, such as a reservoir or field.
When circumstances indicate that the carrying value of proved oil and gas properties may not be recoverable, the Company compares unamortized capitalized costs to the expected undiscounted pre-tax future cash flows for the associated assets grouped at the lowest level for which identifiable cash flows are independent of cash flows of other assets. If the expected undiscounted pre-tax future cash flows, based on Apache’sthe Company’s estimate of future crude oil and natural gas prices, operating costs, anticipated production from proved reserves and other relevant data, are lower than the unamortized capitalized cost, the capitalized cost is reduced to fair value. Fair value is generally estimated using the income approach described in ASC 820. The expected future cash flows used for impairment reviews and related fair value calculations are typically based on judgmental assessments, a Level 3 fair value measurement.
The significant decline in crude oilFor the years ended December 31, 2023, 2022, and natural gas prices, as well as longer-term commodity price outlooks, related to reduced demand for oil and natural gas as a result of2021, the COVID-19 pandemic and related governmental actions indicated possible impairment of the Company’s proved and unproved oil and gas properties in early 2020. In addition to estimating risk-adjusted reserves and future production volumes, estimated future commodity prices are the largest driver in variability of undiscounted pre-tax cash flows. Expected cash flows were estimated based on management’s views of published West Texas Intermediate (WTI), Brent, and Henry Hub forward pricing as of the balance sheet dates. Other significant assumptions and inputs used to calculate estimated future cash flows include estimates for future development activity, exploration plans and remaining lease terms. A 10 percent discount rate, based on a market-based weighted-average cost of capital estimate, was applied to the undiscounted cash flow estimate to value all of the Company’s asset groups that were subject to impairment charges in 2020. Similar assumptions were applied to impairmentsCompany recorded in 2019 and 2018.

Gathering, Processing, and Transmission (GPT) Facilities
GPT facilities totaled $670$448 million and $799$449 million at December 31, 20202023 and 2019,2022, respectively, with accumulated depreciation for these assets totaling $323$373 million and $310$367 million for the respective periods. GPT facilities are depreciated on a straight-line basis over the estimated useful lives of the assets. The estimation of useful life takes into consideration anticipated production lives from the fields serviced by the GPT assets, whether Apache-operated or third party-operated, as well as potential development plans by the Company for undeveloped acreage within, or in close proximity to, those fields.
The Company assesses the carrying amount of its GPT facilities whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the carrying amount of these facilities is more than the sum of the undiscounted cash flows, an impairment loss is recognized for the excess of the carrying value over its fair value.
Apache assessed its long-lived infrastructure assets for impairment at MarchFor the years ended December 31, 2020,2023, 2022, and recorded an impairment of $68 million on its GPT facilities in Egypt during the first quarter of 2020. The fair values of the impaired assets, which were determined to be $46 million, were estimated using the income approach, which considers internal estimates based on future throughput volumes from applicable development concessions in Egypt and estimated costs to operate. These assumptions were applied based on throughput assumptions developed in relation to the oil and gas proved property impairment assessment as discussed above to develop future cash flow projections that were then discounted to estimated fair value, using a 10 percent discount rate, based on a market-based weighted-average cost of capital estimate. Apache has classified these non-recurring fair value measurements as Level 3 in the fair value hierarchy.

As discussed under “Fair Value Measurements” above, the Company decided to materially reduce its planned investment in the Alpine High play during its fourth-quarter 2019 capital planning review. Altus management subsequently assessed its long-lived infrastructure assets for impairment given the expected reduction to future throughput volumes and recorded impairments of $1.3 billion on its gathering, processing, and transmission assets. The fair values of the impaired assets were determined to be $203 million as of the time of the impairment and were estimated using the income approach. The income approach considered internal estimates of future throughput volumes, processing rates, and costs. These assumptions were applied to develop future cash flow projections that were then discounted to estimated fair value, using discount rates believed to be consistent with those applied by market participants. Apache has classified these non-recurring fair value measurements as Level 3 in the fair value hierarchy.

Other Property and EquipmentAltus Midstream
Other property and equipment includes computer software and equipment, buildings, vehicles, furniture and fixtures, land, and other equipment. These assets are depreciated on a straight-line basis over the estimated useful lives of the assets, which range from 3 to 20 years. Other property and equipment totaled $1.1 billion at each of December 31, 2020 and 2019, with accumulated depreciation for these assets totaling $864 million and $817 million at December 31, 2020 and 2019, respectively.
Asset Retirement Costs and Obligations
The initial estimated asset retirement obligation related to property and equipment and subsequent revisions are recorded as a liability at fair value, with an offsetting asset retirement cost recorded as an increasePrior to the associated propertydeconsolidation of Altus on February 22, 2022, the Company’s Altus Midstream segment was operated by ALTM, through its subsidiary, Altus Midstream LP. Altus generated revenue from contracts with customers from its gathering, compression, processing, and equipmenttransmission services provided on the consolidated balance sheet. Revisions in estimated liabilities can result from changes in estimated inflation rates, changes inCompany’s natural gas and natural gas liquid production volumes. Under these long-term commercial service contracts, providing the related service represented a single, distinct performance obligation on behalf of Altus that was satisfied over time. In accordance with the terms of these agreements, Altus primarily received a fixed fee for each contract year, subject to yearly fee escalation recalculations. Revenue was primarily measured using the output method and equipment costs and changesrecognized in the estimated timing of an asset’s retirement. Asset retirement costs are depreciated using a systematic and rational method similaramount to that used forwhich Altus had the associated property and equipment. Accretion expense onright to invoice, as performance completed to date corresponded directly with the liability is recognized overvalue to its customers. For the estimated productive life of the related assets.
CapitalizedInterest
For significant projects, interest is capitalized as part of the historical cost of developing and constructing assets. Significant oil and gas investments in unproved properties actively being explored, significant exploration and development projects that have not commenced production, significant midstream development activities that are in progress, and investments in equity method affiliates that are undergoing the construction of assets that have not commenced principal operations qualify for interest capitalization. Interest is capitalized until the asset is ready for service. Capitalized interest is determined by multiplying the Company’s weighted-average borrowing cost on debt by the average amount of qualifying costs incurred. Once an asset subject to interest capitalization is completed and placed in service, the associated capitalized interest is expensed through depreciation.
Goodwill
Goodwill represents the excess of the purchase price of an entity over the estimated fair value of the assets acquired and liabilities assumed, and it is recorded in “Deferred charges and other” in the Company’s consolidated balance sheet. The Company assesses the carrying amount of goodwill by testing for impairment annually and when impairment indicators arise. The impairment test requires allocating goodwill and all other assets and liabilities to assigned reporting units. Apache assesses each country as a reporting unit, with Egypt being the only reporting unit to have associated goodwill. The fair value of the reporting unit is determined and comparedperiods prior to the book value of the reporting unit. If the fair value of the reporting unit is less than the book value, including goodwill, then goodwill is written downBCP Business Combination, Altus Midstream segment revenues were primarily attributable to its implied fair value through a charge to expense.sales between Altus and APA, which were fully eliminated upon consolidation.

Receivables from contracts with that business is included in the carrying amount to determine the gain or loss on disposal. The amount of goodwill allocated to the carrying amount of a business can significantly impact the amount of gain or loss recognized on the sale of that business. The amount of goodwill to be included in that carrying amount is based on the relative fair value of the business to be disposed of and the portion of the reporting unit that will be retained.

Reductions in estimated net present value of expected future cash flows from oil and gas properties resulted in implied fair values below the carrying values of the Company’s Egypt reporting unit. As a result of these assessments, the Company recognized non-cash impairments of the entire amount of recorded goodwill in the Egypt reporting unit of $87 million. This goodwill impairment has been recorded in “Impairments” in the Company’s statement of consolidated operations.
Commitments and Contingencies
Accruals for loss contingencies arising from claims, assessments, litigation, environmental and other sources are recorded when it is probable that a liability has been incurred and the amount can be reasonably estimated. These accruals are adjusted as additional information becomes available or circumstances change. For more information regarding loss contingencies, refer to Note 11—Commitments and Contingencies.
Revenue Recognition
The years ended 2019 and 2018 include the reclassification of $176 million and $357 million, respectively, from “Other” to “Purchased oil and gas sales,” both within “Revenues and Other” and the respective associated $142 million and $340 million purchased oil and gas costssales and net of allowance for credit losses, were $1.4 billion and $1.3 billion as of December 31, 2023 and 2022, respectively. Payments under all contracts with customers are typically due and received within a short-term period of one year or less, after physical delivery of the product or service has been rendered. Over the past year, the Company experienced a gradual decline in the timeliness of receipts from “Other” within “Revenues and Other” to “Purchasedthe EGPC for the Company’s Egyptian oil and gas costs” within “Operating Expenses” on the Company’s consolidated statement of operations to conform to the current-year presentation.
Upstream
The Company’s upstream oil and gas segments primarily generate revenue from contracts with customers from the sale of its crude oil, natural gas, and natural gas liquids production volumes. In addition to Apache-related production volumes,sales. Although the Company also sells commodity volumes purchasedcontinues to receive periodic payments from third-partiesEGPC, deteriorating economic conditions in Egypt have lessened the availability of U.S. dollars in Egypt, resulting in a delay in receipts from EGPC. Continuation of the currency shortage in Egypt could lead to fulfill sales obligations and commitments asfurther delays, deferrals of payment, or non-payment in the Company’s production fluctuatesfuture; however, the Company currently anticipates that it will ultimately be able to collect its receivable from EGPC.

Company’s efforts to satisfy its obligations. As such, the Company has elected the practical expedients available under the standard to not disclose the aggregate transaction price allocated to unsatisfied, or partially unsatisfied, performance obligations as of the end of the reporting period.
Cash and Cash Equivalents
The Company considers all highly liquid short-term investments with a varietymaturity of factsthree months or less at the time of purchase to be cash equivalents. These investments are carried at cost, which approximates fair value. As of December 31, 2023 and circumstances2022, the Company had $84 million and $185 million, respectively, of cash and cash equivalents. The Company had no restricted cash as of December 31, 2023 and 2022.
Accounts Receivable and Allowance for Credit Losses
Accounts receivable are stated at amortized cost net of an allowance for credit losses. The Company routinely assesses the collectability of its financial assets measured at amortized cost. The Company monitors the credit quality of its counterparties through review of collections, credit ratings, and other analyses. The Company develops its estimated allowance for expected credit losses primarily using an aging method and analyses of historical loss rates as well as consideration of current and future conditions that could impact its counterparties’ credit quality and liquidity.

Revenuesincurred. All costs related to Egypt’s tax volumesproduction, general corporate overhead, and similar activities are considered revenueexpensed as incurred. If an exploratory well provides evidence to justify potential development of reserves, drilling costs associated with the well are initially capitalized, or suspended, pending a determination as to whether a commercially sufficient quantity of proved reserves can be attributed to the area as a result of drilling. This determination may take longer than one year in certain areas depending on, among other things, the amount of hydrocarbons discovered, the outcome of planned geological and engineering studies, the need for additional appraisal drilling activities to determine whether the discovery is sufficient to support an economic development plan, and government sanctioning of development activities in certain international locations. At the end of each quarter, management reviews the status of all suspended exploratory well costs in light of ongoing exploration activities; in particular, whether the Company is making sufficient progress in its ongoing exploration and appraisal efforts or, in the case of discoveries requiring government sanctioning, whether development negotiations are underway and proceeding as planned. If management determines that future appraisal drilling or development activities are unlikely to occur, associated suspended exploratory well costs are expensed.
Acquisition costs of unproved properties are assessed for impairment at least annually and are transferred to proved oil and gas properties to the extent the costs are associated with successful exploration activities. Significant undeveloped leases are assessed individually for impairment based on the Company’s current exploration plans. Unproved oil and gas properties with individually insignificant lease acquisition costs are amortized on a group basis over the average lease term at rates that provide for full amortization of unsuccessful leases upon lease expiration or abandonment. Costs of expired or abandoned leases are charged to exploration expense, while costs of productive leases are transferred to proved oil and gas properties. Costs of maintaining and retaining unproved properties, as well as amortization of individually insignificant leases and impairment of unsuccessful leases, are included in exploration costs in the statement of consolidated operations.
The following table represents non-cash impairment charges of the carrying value of the Company’s unproved properties:

Costs to develop proved reserves, including the costs of all development wells and related equipment used in the production of crude oil and natural gas, are capitalized. Depreciation of the cost of proved oil and gas properties is calculated using the unit-of-production (UOP) method. The UOP calculation multiplies the percentage of estimated proved reserves produced each quarter by the carrying value of associated proved oil and gas properties. The reserve base used to calculate depreciation for leasehold acquisition costs and the cost to acquire proved properties is the sum of proved developed reserves and proved undeveloped reserves. The reserve base used to calculate the depreciation for capitalized well costs is the sum of proved developed reserves only. Estimated future dismantlement, restoration and abandonment costs, net of salvage values, are included in the depreciable cost.

Oil and gas properties are grouped for depreciation in accordance with ASC 932, “Extractive Activities—Oil and Gas.” The basis for grouping is a reasonable aggregation of properties with a common geological structural feature or stratigraphic condition, such as a reservoir or field.
When circumstances indicate that the carrying value of proved oil and gas properties may not be recoverable, the Company compares unamortized capitalized costs to the expected undiscounted pre-tax future cash flows for the associated assets grouped at the lowest level for which identifiable cash flows are independent of cash flows of other assets. If the expected undiscounted pre-tax future cash flows, based on the Company’s estimate of future crude oil and natural gas prices, operating costs, anticipated production from proved reserves and other relevant data, are lower than the unamortized capitalized cost, the capitalized cost is reduced to fair value. Fair value is generally estimated using the income approach described in ASC 820. The expected future cash flows used for impairment reviews and related fair value calculations are typically based on judgmental assessments, a non-customer.Level 3 fair value measurement.
For the years ended December 31, 2023, 2022, and 2021, the Company recorded no impairments of proved properties.
Gains and losses on divestitures of the Company’s oil and gas properties are recognized in the statement of consolidated operations upon closing of the transaction. Refer to Note 17—Business Segment Information3—Acquisitions and Divestitures for more detail.
Gathering, Processing, and Transmission (GPT) Facilities
GPT facilities totaled $448 million and $449 million at December 31, 2023 and 2022, respectively, with accumulated depreciation for these assets totaling $373 million and $367 million for the respective periods. GPT facilities are depreciated on a disaggregationstraight-line basis over the estimated useful lives of revenuethe assets. The estimation of useful life takes into consideration anticipated production lives from the fields serviced by productthe GPT assets, whether Apache-operated or third party-operated, as well as potential development plans by the Company for undeveloped acreage within, or close to, those fields.
The Company assesses the carrying amount of its GPT facilities whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the carrying amount of these facilities is more than the sum of the undiscounted cash flows, an impairment loss is recognized for the excess of the carrying value over its fair value.
For the years ended December 31, 2023, 2022, and reporting segment.2021, the Company recorded no impairments of GPT facilities.
Altus MidstreamFair Value Measurements
The Company’s Altus Midstream segment is operated by ALTM, through its subsidiary, Altus Midstream LP (collectively, Altus). Altus generates revenue from contracts with customers from its gathering, compression, processing,Certain assets and transmission services providedliabilities are reported at fair value on Apache’s natural gas and natural gas liquid production volumes. Under these long-term commercial service contracts, providing the related service represents a single, distinct performance obligation on behalf of Altus that is satisfied over time. In accordance with the terms of these agreements, Altus receives a fixed fee for each contract year, subject to yearly fee escalation recalculations. Revenue is measured using the output method and recognizedrecurring basis in the amount to which Altus has the right to invoice, as performance completed to date corresponds directly with the value to its customers. For the periods presented, Altus Midstream segment revenues were primarily attributable to sales between Altus and Apache, which are fully eliminated upon consolidation.
Payment Terms and Contract Balances
Payments under all contracts with customers are typically due and received within a short-term period of one year or less, after physical delivery of the product or service has been rendered. Receivables from contracts with customers, net of allowance for credit losses, totaled $670 million and $945 million as of December 31, 2020 and 2019, respectively.
In accordance with the provisions of ASC 606, “Revenue from Contracts with Customers,” variable market prices for each short-term commodity sale are allocated entirely to each performance obligation as the terms of payment relate specifically to the Company’s efforts to satisfy its obligations. As such, the Company has elected the practical expedients available under the standard to not disclose the aggregate transaction price allocated to unsatisfied, or partially unsatisfied, performance obligations as of the end of the reporting period.
Derivative Instruments and Hedging Activities
Apache periodically enters into derivative contracts to manage its exposure to commodity price, interest rate, and/or foreign exchange risk. These derivative contracts, which are generally placed with major financial institutions, may take the form of forward contracts, futures contracts, swaps, or options.
All derivative instruments, other than those that meet the normal purchases and sales exception, are recorded on the Company’s consolidated balance sheet as either an asset or liability measured atsheet. Accounting Standards Codification (ASC) 820-10-35, “Fair Value Measurement” (ASC 820), provides a hierarchy that prioritizes and defines the types of inputs used to measure fair value. The Company does not apply hedge accounting to any of its derivative instruments. As a result, gains and losses from the change in fair value hierarchy gives the highest priority to Level 1 inputs, which consist of derivativeunadjusted quoted prices for identical instruments in active markets. Level 2 inputs consist of quoted prices for similar instruments. Level 3 valuations are reported in current-period income as “Derivative instrument losses, net” under “Revenuesderived from inputs that are significant and Other” inunobservable; hence, these valuations have the statement of consolidated operations. Refer to Note 4—Derivative Instruments and Hedging Activities for further information.
Income Taxes
Apache records deferred tax assets and liabilities to account for the expected future tax consequences of events that have been recognized in the financial statements and tax returns. The Company routinely assesses the ability to realize its deferred tax assets. If the Company concludes that it is more likely than not that some or all of the deferred tax assets will not be realized, the tax asset is reduced by a valuation allowance. Numerous judgments and assumptions are inherent in the determination of future taxable income, including factors such as future operating conditions (particularly as related to prevailing oil and gas prices) and changing tax laws.

Earnings Per Sharelowest priority.
The Company’s basicvaluation techniques that may be used to measure fair value include a market approach, an income approach, and a cost approach. A market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities. An income approach uses valuation techniques to convert future amounts to a single present amount based on current market expectations, including present value techniques, option-pricing models, and the excess earnings per share (EPS) amounts have been computedmethod. The cost approach is based on the weighted-average number of shares of common stock outstanding foramount that currently would be required to replace the period. Diluted EPS reflects potential dilution, using the treasury stock method, which assumes that options were exercised and restricted stock was fully vested. The Company uses the “if-converted method” to determine the potential dilutive effectservice capacity of an assumed exchange of the outstanding Preferred Units of Altus Midstream for shares of Altus’ common stock. The impact to net income (loss) attributable to common stock on an assumed conversion of the redeemable noncontrolling Preferred Units interest in Altus Midstream LP were anti-dilutive for the years ended December 31, 2020 and 2019.
Stock-Based Compensation
Apache grants various types of stock-based awards including stock options, restricted stock, cash-settled restricted stock units, and performance-based awards. Stock compensation equity awards granted are valued on the date of grant and are expensed over the required vesting service period. Cash-settled awards are recorded as a liability based on the Company’s stock price and remeasured at the end of each reporting period over the vesting terms. The Company has elected to account for forfeitures as they occur rather than estimate expected forfeitures. The Company’s stock-based compensation plans and related accounting policies are defined and described more fully in Note 14—Capital Stock.
Treasury Stock
The Company follows the weighted-average-cost method of accounting for treasury stock transactions.
Transaction, Reorganization, and Separation (TRS)
In recent years, the Company streamlined its portfolio through strategic divestitures and centralized certain operational activities in an effort to capture greater efficiencies and cost savings through shared services. In light of the continued streamlining of the Company’s asset portfolio through divestitures and strategic transactions, in late 2019 management initiated a comprehensive redesign of Apache’s organizational structure and operations. Reorganization efforts were substantially completed during 2020. Apache has incurred a cumulative total of $79 million of reorganization costs through December 31, 2020, all of which were paid in 2020.
The Company recorded $54 million, $50 million, and $28 million of TRS costs in 2020, 2019, and 2018, respectively. TRS costs incurred in 2020 relate to $51 million of separation costs associated with the reorganization, $2 million for transaction consulting fees, and $1 million of office closure costs. TRS costs incurred in 2019 associated with the reorganization include $26 million and $2 million for employee termination benefits and consulting fees related to the reorganization, respectively. The Company also incurred $15 million of expenses for employee termination benefits and office closures associated with other reorganization efforts and $7 million for consulting and legal fees on various transactions throughout 2019. Charges for 2018 include $22 million for consulting and legal fees related to divestitures and the Altus transaction, and $6 million related to employee separations.

In the third quarter of 2019, Apache completed the sale of non-core assets in the western Anadarko Basin of Oklahoma and Texas for aggregate cash proceeds of approximately $322 million and the assumption of asset retirement obligations of $49 million. These assets met the criteria to be classified as held for sale in the second quarter of 2019. Accordingly, the Company performed a fair value assessment of the assets and recorded impairments of $240 million to the carrying value of proved and unproved oil and gas properties, other fixed assets, and working capital. The transaction closed in the third quarter of 2019, and the Company recognized a $7 million loss in connection with the sale.
In the second quarter of 2019, Apache completed the sale of certain non-core assets in Oklahoma that had a net carrying value of $206 million for aggregate cash proceeds of approximately $223 million. The Company recognized a $17 million gain in connection with the sale.
During 2019, the Company also completed the sale of certain other non-core producing assets, GPT assets, and leasehold acreage, primarily in the Permian Basin, in multiple transactions for total cash proceeds of $73 million. The Company recognized a net gain of approximately $33 million upon closing of these transactions.
Suriname Joint Venture Agreement
In December 2019, Apache entered into a joint venture agreement with Total S.A. to explore and develop Block 58 offshore Suriname. Under the terms of the agreement, Apache and Total S.A. each hold a 50 percent working interest in Block 58. Pursuant to the agreement, Apache operated the drilling of the first four wells, the Maka Central-1, Sapakara West-1, Kwaskwasi-1, and Keskesi East-1, and subsequently transferred operatorship of Block 58 to Total S.A. on January 1, 2021. Apache will continue to operate the Keskesi exploration well until completion of drilling operations.
In connection with the agreement, Apache received $100 million from Total S.A. upon closing in the fourth quarter of 2019 and $79 million upon satisfying certain closing conditions in the first quarter of 2020 for reimbursement of 50 percent of all costs incurred on Block 58 as of December 31, 2019. All proceeds were applied against the carrying value of the Company’s Suriname properties and associated inventory. The Company recognized a $19 million gain in the first quarter of 2020 associated with the transaction.
Apache will also receive various other forms of consideration, including $5.0 billion of cash carry on Apache’s first $7.5 billion of appraisal and development capital, 25 percent cash carry on all of Apache’s appraisal and development capital beyond the first $7.5 billion, a $75 million cash payment upon achieving first oil production, and future contingent royalty payments from successful joint development projects.

2018 Activity
Altus Transaction
In November 2018, Apache completed a transaction with Altus Midstream Company to create a pure-play, Permian Basin midstream C-corporation anchored by the Company’s GPT assets at Alpine High. Pursuant to the agreement, the Company contributed certain Alpine High midstream assets and the Pipeline Options to Altus and/or its subsidiaries. Altus Midstream Company contributed approximately $628 million of cash, net of transaction expenses. The transaction was accounted for by Altus as a reverse recapitalization. Under this method of accounting, Altus Midstream Company was treated as the “acquired” company, and Apache’s contributed assets of approximately $1.1 billion remained at historical cost, with no goodwill or other intangible assets recorded. Apache owns an approximate 79 percent ownership interest in Altus.
Apache fully consolidates the assets and liabilities of Altus in its consolidated financial statements, with a corresponding noncontrolling interest reflected separately. Apache recorded a noncontrolling interest of $406 million upon closing, which is reflected as a separate component of equity in the Company’s consolidated balance sheet. This represents approximately 21 percent third party ownership of the net assets in Altus at the time of the transaction. The cash contributions in excess of the noncontrolling interest were recognized as additional paid-in capital.
Other Activity
During 2018, the Company completed the sale of certain non-core assets and leasehold, primarily in the North Sea and Permian Basin, in multiple transactions for total cash proceeds of $138 million. The Company recognized gainsalso uses fair value measurements on a nonrecurring basis when certain qualitative assessments of approximately $23 million during 2018 upon the closing of these transactions.its assets indicate a potential impairment.

Objectives and Strategies
Apache is exposed to fluctuations in crudeCompany’s upstream oil and natural gas prices onsegments primarily generate revenue from contracts with customers from the majority of its worldwide production, as well as transactions denominated in foreign currencies. The Company manages the variability in its cash flows by occasionally entering into derivative transactions on a portionsale of its crude oil, natural gas, and natural gas liquids production volumes. In addition to Apache-related production volumes, the Company also sells commodity volumes purchased from third parties to provide flexibility to fulfill sales obligations and commitments. Under these commodity sales contracts, the physical delivery of each unit of quantity represents a single, distinct performance obligation on behalf of the Company. Contract prices are determined based on market-indexed prices, adjusted for quality, transportation, and other market-reflective differentials. Revenue is measured by allocating an entirely variable market price to each performance obligation and recognized at a point in time when control is transferred to the customer. The Company considers a variety of facts and circumstances in assessing the point of control transfer, including but not limited to: whether the purchaser can direct the use of the hydrocarbons, the transfer of significant risks and rewards, and the Company’s right to payment. Control typically transfers to customers upon the physical delivery at specified locations within each contract and the transfer of title.
The Company’s Egypt operations are conducted pursuant to production-sharing contracts (PSCs). Under the terms of the Company’s PSCs, the Company is the contractor partner (Contractor) with the Egyptian General Petroleum Corporation (EGPC) and bears the risk and cost of exploration, development, and production activities. In return, if exploration is successful, the Contractor receives entitlement to variable physical volumes of hydrocarbons, representing recovery of the costs incurred and a stipulated share of production after cost recovery. Additionally, the Contractor’s income taxes, which remain the liability of the Contractor under domestic law, are paid by EGPC on behalf of the Contractor out of EGPC’s production entitlement. Income taxes paid to the Arab Republic of Egypt on behalf of the Contractor are recognized as oil and gas sales revenue and income tax expense and reflected as production and foreign currency transactions. The Company utilizes various typesestimated reserves. Because Contractor cost recovery entitlement and income taxes paid on its behalf are determined as a monetary amount, the quantities of derivative financial instruments, including forward contracts, futures contracts, swaps,production entitlement and options,estimated reserves attributable to manage fluctuations in cash flows resulting from changes inthese monetary amounts will fluctuate with commodity prices or foreign currency values.
Counterparty Risk
The use of derivative instruments exposes the Company to credit loss in the event of nonperformance by the counterparty. To reduce the concentration of exposure to any individual counterparty, Apache utilizes a diversified group of investment-grade rated counterparties, primarily financial institutions, for its derivative transactions. As of December 31, 2020, the Company had derivative positions with 6 counterparties. The Company monitors counterparty creditworthiness on an ongoing basis; however, it cannot predict sudden changes in counterparties’ creditworthiness.prices. In addition, even if such changesbecause the Contractor income taxes are not sudden,paid by EGPC, the Company may be limited in its ability to mitigate an increase in counterparty credit risk. Should oneamount of these counterparties not perform, Apache may not realize the benefit of some of its derivative instruments resulting from changes in commodity prices, currency exchange rates, or interest rates.

Pipeline Capacity Embedded Derivatives
During the fourth quarter of 2019 and first quarter of 2020, Apache entered into separate agreements to assign a portion of its contracted capacity under an existing transportation agreement to third parties. Embedded in these agreements are arrangements under which Apache has the potential to receive payments calculated based on pricing differentials between Houston Ship Channel and Waha during calendar years 2020 and 2021. These features require bifurcation and measurement of the change in market values for each period. Unrealized gains or losses in the fair value of these features are recorded as “Derivative instrument losses, net” under “Revenues and Other” in the statement of consolidated operations. Any proceeds received will be deferred and reflected in income over the original tenure of the transportation agreement.
Fair Value Measurements

Accounting Standards Codification (ASC) 820-10-35, “Fair Value Measurement” (ASC 820), provides a hierarchy that prioritizes and defines the types of inputs used to measure fair value. The fair value hierarchy gives the highest priority to Level 1 inputs, which consist of unadjusted quoted prices for identical instruments in active markets. Level 2 inputs consist of quoted prices for similar instruments. Level 3 valuations are derived from inputs that are significant and unobservable; hence, these valuations have the lowest priority.

The Company’s upstream oil and gas segments primarily generate revenue from contracts with customers from the sale of its crude oil, natural gas, and natural gas liquids production volumes. In addition to Apache-related production volumes, the Company also sells commodity volumes purchased from third parties to provide flexibility to fulfill sales obligations and commitments. Under these commodity sales contracts, the physical delivery of each unit of quantity represents a single, distinct performance obligation on behalf of the Company.

Income taxes paid to the Arab Republic of Egypt on behalf of the Contractor are recognized as oil and gas sales revenue and income tax expense and reflected as production and estimated reserves. Because Contractor cost recovery entitlement and income taxes paid on its behalf are determined as a gross basis, excludingmonetary amount, the quantities of production entitlement and estimated reserves attributable to these monetary amounts will fluctuate with commodity prices. In addition, because the Contractor income taxes are paid by EGPC, the amount of the income tax has no economic impact on the Company’s Egypt operations despite impacting the Company’s production and reserves.

Altus Midstream
Prior to the deconsolidation of Altus on February 22, 2022, the Company’s Altus Midstream segment was operated by ALTM, through its subsidiary, Altus Midstream LP. Altus generated revenue from contracts with customers from its gathering, compression, processing, and transmission services provided on the Company’s natural gas and natural gas liquid production volumes. Under these long-term commercial service contracts, providing the related service represented a single, distinct performance obligation on behalf of Altus that was satisfied over time. In accordance with the terms of these agreements, Altus primarily received a fixed fee for each contract year, subject to yearly fee escalation recalculations. Revenue was primarily measured using the output method and recognized in the amount to which Altus had the right to invoice, as performance completed to date corresponded directly with counterparties.the value to its customers. For the periods prior to the BCP Business Combination, Altus Midstream segment revenues were primarily attributable to sales between Altus and APA, which were fully eliminated upon consolidation.

Payment Terms and Contract Balances
Receivables from contracts with customers, including receivables for purchased oil and gas sales and net of allowance for credit losses, were $1.4 billion and $1.3 billion as of December 31, 2023 and 2022, respectively. Payments under all contracts with customers are typically due and received within a short-term period of one year or less, after physical delivery of the product or service has been rendered. Over the past year, the Company experienced a gradual decline in the timeliness of receipts from the EGPC for the Company’s Egyptian oil and gas sales. Although the Company continues to receive periodic payments from EGPC, deteriorating economic conditions in Egypt have lessened the availability of U.S. dollars in Egypt, resulting in a delay in receipts from EGPC. Continuation of the currency shortage in Egypt could lead to further delays, deferrals of payment, or non-payment in the future; however, the Company currently anticipates that it will ultimately be able to collect its receivable from EGPC.
In accordance with the provisions of ASC 606, “Revenue from Contracts with Customers,” variable market prices for each short-term commodity sale are allocated entirely to each performance obligation as the terms of payment relate specifically to the Company’s efforts to satisfy its obligations. As such, the Company has elected the practical expedients available under the standard to not disclose the aggregate transaction price allocated to unsatisfied, or partially unsatisfied, performance obligations as of the end of the reporting period.
Cash and Cash Equivalents
The Company considers all highly liquid short-term investments with a maturity of three months or less at the time of purchase to be cash equivalents. These investments are carried at cost, which approximates fair value. As of December 31, 2023 and 2022, the Company had $84 million and $185 million, respectively, of cash and cash equivalents. The Company had no restricted cash as of December 31, 2023 and 2022.
Accounts Receivable and Allowance for Credit Losses
Accounts receivable are stated at amortized cost net of an allowance for credit losses. The Company routinely assesses the collectability of its financial assets measured at amortized cost. The Company monitors the credit quality of its counterparties through review of collections, credit ratings, and other analyses. The Company develops its estimated allowance for expected credit losses primarily using an aging method and analyses of historical loss rates as well as consideration of current and future conditions that could impact its counterparties’ credit quality and liquidity.

Inventories
Inventories consist principally of tubular goods and equipment and are stated at the lower of weighted-average cost or net realizable value. Oil produced but not sold, primarily in the North Sea, is also recorded to inventory and is stated at the lower of the cost to produce or net realizable value.
During 2023, the Company recorded $50 million of impairments in connection with valuations of drilling and operations equipment inventory upon the Company’s decision to suspend drilling operations in the North Sea.

The Company primarily uses a market approachcost incurred to estimateacquire the property and equipment, including capitalized interest, net of any impairments. For business combinations and acquisitions, property and equipment cost is based on the fair values at the acquisition date.
Oil and Gas Property
The Company follows the successful efforts method of these derivativesaccounting for its oil and gas property. Under this method of accounting, exploration costs, such as exploratory geological and geophysical costs, delay rentals, and exploration overhead, are expensed as incurred. All costs related to production, general corporate overhead, and similar activities are expensed as incurred. If an exploratory well provides evidence to justify potential development of reserves, drilling costs associated with the well are initially capitalized, or suspended, pending a determination as to whether a commercially sufficient quantity of proved reserves can be attributed to the area as a result of drilling. This determination may take longer than one year in certain areas depending on, among other things, the amount of hydrocarbons discovered, the outcome of planned geological and engineering studies, the need for additional appraisal drilling activities to determine whether the discovery is sufficient to support an economic development plan, and government sanctioning of development activities in certain international locations. At the end of each quarter, management reviews the status of all suspended exploratory well costs in light of ongoing exploration activities; in particular, whether the Company is making sufficient progress in its ongoing exploration and appraisal efforts or, in the case of discoveries requiring government sanctioning, whether development negotiations are underway and proceeding as planned. If management determines that future appraisal drilling or development activities are unlikely to occur, associated suspended exploratory well costs are expensed.
Acquisition costs of unproved properties are assessed for impairment at least annually and are transferred to proved oil and gas properties to the extent the costs are associated with successful exploration activities. Significant undeveloped leases are assessed individually for impairment based on the Company’s current exploration plans. Unproved oil and gas properties with individually insignificant lease acquisition costs are amortized on a recurringgroup basis utilizing futures pricingover the average lease term at rates that provide for full amortization of unsuccessful leases upon lease expiration or abandonment. Costs of expired or abandoned leases are charged to exploration expense, while costs of productive leases are transferred to proved oil and gas properties. Costs of maintaining and retaining unproved properties, as well as amortization of individually insignificant leases and impairment of unsuccessful leases, are included in exploration costs in the underlying positions provided by a reputable third party, a Level 2 fair value measurement.statement of consolidated operations.

Costs to develop proved reserves, including the costs of all development wells and related equipment used in the production of crude oil and natural gas, are capitalized. Depreciation of the cost of proved oil and gas properties is calculated using anthe unit-of-production (UOP) method. The UOP calculation multiplies the percentage of estimated proved reserves produced each quarter by the carrying value of associated proved oil and gas properties. The reserve base used to calculate depreciation for leasehold acquisition costs and the cost to acquire proved properties is the sum of proved developed reserves and proved undeveloped reserves. The reserve base used to calculate the depreciation for capitalized well costs is the sum of proved developed reserves only. Estimated future dismantlement, restoration and abandonment costs, net of salvage values, are included in the depreciable cost.

APACHE CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)
Oil and gas properties are grouped for depreciation in accordance with ASC 932, “Extractive Activities—Oil and Gas.” The basis for grouping is a reasonable aggregation of properties with a common geological structural feature or stratigraphic condition, such as a reservoir or field.
When circumstances indicate that the carrying value of proved oil and gas properties may not be recoverable, the Company compares unamortized capitalized costs to the expected undiscounted pre-tax future cash flows for the associated assets grouped at the lowest level for which identifiable cash flows are independent of cash flows of other assets. If the expected undiscounted pre-tax future cash flows, based on the Company’s estimate of future crude oil and natural gas prices, operating costs, anticipated production from proved reserves and other relevant data, are lower than the unamortized capitalized cost, the capitalized cost is reduced to fair value. Fair value is generally estimated using the income approach described in ASC 820. The expected future cash flows used for impairment reviews and related fair value calculations are typically based on judgmental assessments, a Level 3 fair value measurement.
For the years ended December 31, 2023, 2022, and 2021, the Company recorded no impairments of proved properties.
Gains and losses on divestitures of the Company’s oil and gas properties are recognized in the statement of consolidated operations upon closing of the transaction. Refer to Note 3—Acquisitions and Divestitures for more detail.
Gathering, Processing, and Transmission (GPT) Facilities
GPT facilities totaled $448 million and $449 million at December 31, 2023 and 2022, respectively, with accumulated depreciation for these assets totaling $373 million and $367 million for the respective periods. GPT facilities are depreciated on a straight-line basis over the estimated useful lives of the assets. The estimation of useful life takes into consideration anticipated production lives from the fields serviced by the GPT assets, whether Apache-operated or third party-operated, as well as potential development plans by the Company for undeveloped acreage within, or close to, those fields.
The Company assesses the carrying amount of its GPT facilities whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the carrying amount of these facilities is more than the sum of the undiscounted cash flows, an impairment loss is recognized for the excess of the carrying value over its fair value.
For the years ended December 31, 2023, 2022, and 2021, the Company recorded no impairments of GPT facilities.
Other Property and Equipment
Other property and equipment includes computer software and equipment, buildings, vehicles, furniture and fixtures, land, and other equipment. These assets are depreciated on a straight-line basis over the estimated useful lives of the assets, which range from 3 to 20 years. Other property and equipment, net of accumulated depreciation totaled $217 million and $206 million at December 31, 2023 and 2022, respectively.
Asset Retirement Costs and Obligations
The initial estimated asset retirement obligation related to property and equipment and subsequent revisions are recorded as a liability at fair value, determination is basedwith an offsetting asset retirement cost recorded as an increase to the associated property and equipment on a range of factors, including expected future interestthe consolidated balance sheet. Revisions in estimated liabilities can result from changes in estimated inflation rates, using the Black-Karasinski model, Altus’ imputed interest rate, interest rate volatility, the expected timing of periodic cash distributions,changes in service and equipment costs and changes in the estimated timing of an asset’s retirement. Asset retirement costs are depreciated using a systematic and rational method similar to that used for the potential exerciseassociated property and equipment. Accretion expense on the liability is recognized over the estimated productive life of the exchange option, and anticipated dividend yieldsrelated assets.
CapitalizedInterest
For significant projects, interest is capitalized as part of the Preferred Units. Ashistorical cost of developing and constructing assets. Significant oil and gas investments in unproved properties actively being explored, significant exploration and development projects that have not commenced production, significant midstream development activities that are in progress, and investments in equity method affiliates that are undergoing the construction of assets that have not commenced principal operations qualify for interest capitalization. Interest is capitalized until the asset is ready for service. Capitalized interest is determined by multiplying the Company’s weighted-average borrowing cost on debt by the average amount of qualifying costs incurred. Once an asset subject to interest capitalization is completed and placed in service, the associated capitalized interest is expensed through depreciation.

Prior to the deconsolidation of Altus on February 22, 2022, in the fourth quarter of 2021, Altus, as part of its review of the fair value of its assets in relation to the BCP Business Combination, determined the fair value of a pipeline investment was below carrying value. As such, in the fourth quarter of 2021, Altus recorded an impairment charge of $160 million on its equity method interest in the pipeline.
Commitments and Contingencies
Accruals for loss contingencies arising from claims, assessments, litigation, environmental and other sources are recorded when it is probable that a liability has been incurred and the amount can be reasonably estimated. These accruals are adjusted as additional information becomes available or circumstances change. For more information regarding loss contingencies, refer to Note 12—Commitments and Contingencies.
Derivative Instruments and Hedging Activities
The Company periodically enters into derivative contracts to manage its exposure to commodity price, interest rate, and/or foreign exchange risk. These derivative contracts, which are generally placed with major financial institutions, may take the form of forward contracts, futures contracts, swaps, or options.
All derivative instruments, other than those that meet the normal purchases and sales exception, are recorded on the Company’s consolidated balance sheet as either an asset or liability measured at fair value. The Company does not apply hedge accounting to any of its derivative instruments. As a result, gains and losses from the change in fair value of derivative instruments are reported in current-period income as “Derivative instrument gains (losses), net” under “Revenues and Other” in the statement of consolidated operations. Refer to Note 5—Derivative Instruments and Hedging Activities for further information.
Income Taxes
Apache records deferred tax assets and liabilities to account for the expected future tax consequences of events that have been recognized in the financial statements and tax returns. The Company routinely assesses the ability to realize its deferred tax assets. If the Company concludes that it is more likely than not that some or all of the deferred tax assets will not be realized, the tax asset is reduced by a valuation allowance. Numerous judgments and assumptions are inherent in the determination of future taxable income, including factors such as future operating conditions (particularly as related to prevailing oil and gas prices) and changing tax laws.
Apache is a directly owned subsidiary of APA and is included in APA and its subsidiaries’ U.S. Federal income tax return. The Company’s financial statements recognize the current and deferred income tax consequences that result from Apache’s activities during the current period pursuant to the provisions of ASC Topic 740 “Income Taxes” as if the Company were a separate taxpayer rather than a member of APA’s consolidated income tax return group. Refer to Note 11—Income Taxes for further information.

Prior to consummation of the Holding Company Reorganization, Apache granted various types of stock-based awards including stock options, restricted stock, cash-settled restricted stock units, and performance-based awards. Stock compensation equity awards granted are valued on the date of grant and are expensed over the required vesting service period. Cash-settled awards are recorded as a liability based on APA’s stock price and remeasured at the end of each reporting period over the vesting terms. The Company has elected to account for forfeitures as they occur rather than estimate expected forfeitures. The Company’s stock-based compensation plans, which were assumed by APA pursuant to the Holding Company Reorganization, and related accounting policies are defined and described more fully in Note 15—Capital Stock.

New Pronouncements Issued But Not Yet Adopted
In November 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2023-07, “Segment Reporting (Topic 280),” which expands disclosures about a public entity’s reportable segments and requires more enhanced information about a reportable segment’s expenses, interim segment profit or loss, and how a public entity’s chief operating decision maker uses reported segment profit or loss information in assessing segment performance and allocating resources. The amendments do not change or remove existing disclosure requirements or how a public entity identifies its operating segments, aggregates those operating segments, or applies the quantitative thresholds to determine its reportable segments. The amendments are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted, and the amendments are required to be applied on a retrospective basis. The Company is currently assessing the impact of adopting this standard and does not believe this will have a material impact on its financial statements.
In December 2023, the FASB issued ASU 2023-09 “Improvements to Income Tax Disclosures (Topic 740),” which requires enhanced disclosures primarily related to existing rate reconciliation and income taxes paid information.

The ARO liability reflects the estimated present value of the amount of dismantlement, removal, site reclamation, and similar activities associated with Apache’sthe Company’s oil and gas properties and other long-lived assets. The Company utilizes current retirement costs to estimate the expected cash outflows for retirement obligations. The Company estimates the ultimate productive life of the properties, a risk-adjusted discount rate, and an inflation factor in order to determine the current present value of this obligation. To the extent future revisions to these assumptions impact the present value of the existing ARO liability, a corresponding adjustment is made to the oil and gas property or other long-lived asset balance.

Environmental Matters
The Company, as an owner or lessee and operator of oil and gas properties, is subject to various federal, state, local, and foreign country laws and regulations relating to discharge of materials into, and protection of, the environment. These laws and regulations may, among other things, impose liability on the lessee under an oil and gas lease for the cost of pollution clean-up resulting from operations and subject the lessee to liability for pollution damages. In some instances, the Company may be directed to suspend or cease operations in the affected area. The Company maintains insurance coverage, which it believes is customary in the industry, although the Company is not fully insured against all environmental risks.
The Company manages its exposure to environmental liabilities on properties to be acquired by identifying existing problems and assessing the potential liability. The Company also conducts periodic reviews, on a Company-wide basis, to identify changes in its environmental risk profile. These reviews evaluate whether there is a probable liability, the amount, and the likelihood that the liability will be incurred. The amount of any potential liability is determined by considering, among other matters, incremental direct costs of any likely remediation and the proportionate cost of employees who are expected to devote a significant amount of time directly to any possible remediation effort. As it relates to evaluations of purchased properties, depending on the extent of an identified environmental problem, the Company may exclude a property from the acquisition, require the seller to remediate the property to the Company’s satisfaction, or agree to assume liability for the remediation of the property. The Company’s general policy is to limit any reserve additions to any incidents or sites that are considered probable to result in an expected remediation cost exceeding $300,000. Any environmental costs and liabilities that are not reserved for are treated as an expense when actually incurred. In the Company’s estimation, neither these expenses nor expenses related to training and compliance programs are likely to have a material impact on its financial condition.
As of December 31, 2020,2023, the Company had an undiscounted reserve for environmental remediation of approximately $2$5 million.

On September 11, 2020, the Company received a Notice of Violation and Finding of Violation, and accompanying Clean Air Act Information Request, from the U.S. Environmental Protection Agency (EPA) following site inspections in April 2019 at several of the Company’s oil and natural gas production facilities in Lea and Eddy Counties, New Mexico. The notice and information request involve alleged emissions control and reporting violations. The Company is cooperating with the EPA and responding to the information request. The EPA has not commenced enforcement proceedings, and at this time the Company is unable to reasonably estimate whether such proceedings will result in monetary sanctions and, if so, whether they would be more or less than $100,000, exclusive of interest and costs.

Fieldwood has submitted aOn June 25, 2021, the United States Bankruptcy Court for the Southern District of Texas (Houston Division) entered an order confirming Fieldwood’s bankruptcy plan.

Pursuant to the Company has been engaged in discussions with Fieldwood and other interested parties regarding such plan. If approved byplan, the bankruptcy court, the submitted plan would separate the TransferredLegacy GOM Assets were separated into a standalone company, andwhich was subsequently merged into GOM Shelf. Under GOM Shelf’s limited liability company agreement, the proceeds of production of the TransferredLegacy GOM Assets will be used forto fund the AROs. Ifoperation of GOM Shelf and the proceedsdecommissioning of production are insufficient forLegacy GOM Assets.
By letter dated April 5, 2022, replacing two prior letters dated September 8, 2021 and February 22, 2022, and by subsequent letter dated March 1, 2023, GOM Shelf notified the Bureau of Safety and Environmental Enforcement (BSEE) that it was unable to fund the decommissioning obligations that it is currently obligated to perform on certain of the Legacy GOM Assets. As a result, Apache and other current and former owners in these assets have received orders from BSEE to decommission certain of the Legacy GOM Assets included in GOM Shelf’s notifications to BSEE. Apache expects to receive similar orders on the other Legacy GOM Assets included in GOM Shelf’s notification letters. Apache has also received orders to decommission other Legacy GOM Assets that were not included in GOM Shelf’s notification letters. Further, Apache anticipates that GOM Shelf may send additional such AROs, then Apache expectsnotices to BSEE in the future and that it may be required by the relevant governmental authoritiesreceive additional orders from BSEE requiring it to perform such AROs,decommission other Legacy GOM Assets.
As of December 31, 2023, Apache has incurred $819 million in which casedecommissioning costs related to Legacy GOM Assets. GOM Shelf did not, and has confirmed that it will applynot, reimburse Apache for these decommissioning costs. As a result, Apache has sought and will continue to seek reimbursement from its security for these costs. As of December 31, 2023, $293 million has been reimbursed from Trust A and $336 million has been reimbursed from the Letters of Credit. If GOM Shelf does not reimburse Apache for further decommissioning costs incurred with respect to Legacy GOM Assets, then Apache will continue to seek reimbursement from Trust A, to the extent of available funds, and thereafter, will seek reimbursement from the Bonds remainingand the Letters of Credit until all such funds and Trust A to pay for the AROs.securities are fully utilized. In addition, after such sources have been exhausted, Apache has agreed to provide a standby loan to GOM Shelf of up to $400 million for the new company to perform decommissioning (Standby Loan Agreement), with such standby loan secured by a first and prior lien on the TransferredLegacy GOM Assets.
If the foregoingcombination of GOM Shelf’s net cash flow from its producing properties, the Trust A funds, the Bonds, and the remaining Letters of Credit are insufficient to fully fund decommissioning of any Legacy GOM Assets that Apache may be required to perform or fund, or if GOM Shelf’s net cash flow from its remaining producing properties after the Trust A funds, Bonds, and Letters of Credit are exhausted is insufficient to repay any loans made by Apache under the CompanyStandby Loan Agreement, then Apache may be forced to use its available cash to coverfund the deficit.
As of December 31, 2023, Apache estimates that its potential liability to fund the remaining decommissioning of Legacy GOM Assets it may be ordered to perform or fund ranges from $824 million to $1.2 billion on an undiscounted basis. Management does not believe any additionalspecific estimate within this range is a better estimate than any other. Accordingly, the Company has recorded a contingent liability of $824 million as of December 31, 2023, representing the estimated costs of decommissioning it incurs for performing such AROs.
Leases and Contractual Obligations
On January 1, 2019, Apache adopted ASU 2016-02, “Leases (Topic 842),” which requires lesseesmay be required to recognize separate right-of-use (ROU) assets and lease liabilities for most leases classified as operating leases under previous GAAP. As allowedperform or fund on Legacy GOM Assets. Of the total liability recorded, $764 million is reflected under the standard,caption “Decommissioning contingency for sold Gulf of Mexico properties,” and $60 million is reflected under “Other current liabilities” in the Company’s consolidated balance sheet. Changes in significant assumptions impacting Apache’s estimated liability, including expected decommissioning rig spread rates, lift boat rates, and planned abandonment logistics could result in a liability in excess of the amount accrued.

On June 21, 2023, the two sureties that issued bonds directly to Apache and two sureties that issued bonds to the issuing bank on the Letters of Credit filed suit against Apache in a case styled Zurich American Insurance Company, HCC International Insurance Company PLC, Philadelphia Indemnity Insurance Company and Everest Reinsurance Company (Insurers) v. Apache Corporation, Cause No. 2023-38238 in the 281st Judicial District Court, Harris County Texas. Insurers are seeking to prevent Apache from drawing on the Bonds and Letters of Credit and further allege that they are discharged from their reimbursement obligations related to decommissioning costs and are entitled to other relief. On July 20, 2023, the 281st Judicial District Court denied the Insurers’ request for a temporary injunction. On July 26, 2023, Apache removed the suit to the United States Bankruptcy Court for the Southern District of Texas (Houston Division) which subsequently held that the sureties’ state court lawsuit violated the terms of the Bankruptcy Confirmation Order and is void. Apache has drawn down the entirety of the Letters of Credit and is vigorously pursuing its claims against the sureties.
Leases and Contractual Obligations
The Company determines if an arrangement is an operating or finance lease at the inception of each contract. If the contract is classified as an operating lease, Apache records an ROU asset and corresponding liability reflecting the total remaining present value of fixed lease payments over the expected term of the lease agreement. The expected term of the lease may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. If the Company’s lease does not provide an implicit rate in the contract, the Company uses its incremental borrowing rate when calculating the present value. In the normal course of business, Apache enters into various lease agreements for real estate, drilling rigs, vessels, aircrafts, and equipment related to its exploration and development activities, which are typically classified as operating leases under the provisions of the standard. ROU assets are reflected within “Deferred charges and other” within “Other” assetsother assets” on the Company’s consolidated balance sheet, and the associated operating lease liabilities are reflected within “Other current liabilities” and “Other” within “Deferred Credits and Other Noncurrent Liabilities,” as applicable.
Operating lease expense associated with ROU assets is recognized on a straight-line basis over the lease term. Lease expense is reflected on the statement of consolidated operations commensurate with the leased activities and nature of the services performed. Gross fixed operating lease expense, inclusive of amounts billable to partners and other working interest owners, was $149$167 million, $144 million, and $222$127 million in 2020for the years ended 2023, 2022, and 2019,2021, respectively. As allowed under the standard, Apache accounts for non-lease and lease components as a single lease component for all asset classes and has elected to exclude short-term leases (those with terms of 12 months or less) from the balance sheet presentation. Costs incurred for short-term leases, which isare primarily related to drillingdecommissioning activities in Block 58 offshore Suriname, was $80 million and $18the Gulf of Mexico, were $71 million in 20202023 and 2019, respectively.not significant in 2022 and 2021.
In addition, the Company periodically enters into finance leases that are similar to those leases classified as capital leases under previous GAAP. Finance lease assets are included in “Other” within “Property, Plant, and Equipment” on the consolidated balance sheet, and the associated finance lease liabilities are reflected within “Current debt”Current debt and “Long-termLong-term debt,” as applicable. Depreciation on the Company’s finance lease asset was $2 million in each of the years 2023, 2022, and $7 million in 2020 and 2019, respectively.2021.

The derivative is reflected in “Other” within “Deferred Credits and Other Noncurrent Liabilities” on the Company’s consolidated balance sheet at its current fair value of $139 million as of December 31, 2020. The fair value of the embedded derivative, a Level 3 fair value measurement, was based on numerous factors including expected future interest rates using the Black-Karasinski model, Altus’ imputed interest rate, the timing of periodic cash distributions, and dividend yields of the Preferred Units. See Note 4—Derivative Instruments and Hedging Activities for more detail.

Oil and Gas Reserve Information
Proved oil and gas reserves are those quantities of natural gas, crude oil, condensate, and NGLs, which by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible from a given date forward, from known reservoirs, and under existing economic conditions, operating methods, and government regulations. Estimated proved developed oil and gas reserves can be expected to be recovered through existing wells with existing equipment and operating methods. The Company reports all estimated proved reserves held under production-sharing arrangements utilizing the “economic interest” method, which excludes the host country’s share of reserves.
Estimated reserves that can be produced economically through application of improved recovery techniques are included in the “proved” classification when successful testing by a pilot project or the operation of an active, improved recovery program using reliable technology establishes the reasonable certainty for the engineering analysis on which the project or program is based. Economically producible means a resource that generates revenue that exceeds, or is reasonably expected to exceed, the costs of the operation. Reasonable certainty means a high degree of confidence that the quantities will be recovered. Reliable technology is a grouping of one or more technologies (including computational methods) that has been field-tested and has been demonstrated to provide reasonably certain results with consistency and repeatability in the formation being evaluated or in an analogous formation. In estimating its proved reserves, Apache uses several different traditional methods that can be classified in three general categories: (1) performance-based methods; (2) volumetric-based methods; and (3) analogy with similar properties. Apache will, at times, utilize additional technical analysis such as computer reservoir models, petrophysical techniques, and proprietary 3-D seismic interpretation methods to provide additional support for more complex reservoirs. Information from this additional analysis is combined with traditional methods outlined above to enhance the certainty of the Company’s reserve estimates.

As of December 31, 2021, approximately 96 percent of the Company’s Egypt reserves were consolidated within the modernized PSC. These estimates include Sinopec’s noncontrolling interest in Egypt.
Approximately 10 percent of the Company’s year-end 20202023 estimated proved developed reserves are classified as proved not producing. These reserves relate to zones that are either behind pipe, or that have been completed but not yet produced, or zones that have been produced in the past, but are not now producing because of mechanical reasons. These reserves are considered to be a lower tier of reserves than producing reserves because they are frequently based on volumetric calculations rather than performance data. Future production associated with behind pipe reserves is scheduled to follow depletion of the currently producing zones in the same wellbores. Additional capital may have to be spent to access these reserves. The capital and economic impact of production timing are reflected in this Note 18, under “Future Net Cash Flows.”

Future Net Cash Flows
Future cash inflows as of December 31, 2020, 2019,2023, 2022, and 20182021 were calculated using an unweighted arithmetic average of oil and gas prices in effect on the first day of each month in the respective year, except where prices are defined by contractual arrangements. Operating costs, production and ad valorem taxes and future development costs are based on current costs with no escalation. Future development costs include abandonment and dismantlement costs.

The following table sets forth unaudited information concerning future net cash flows for proved oil and gas reserves, net of income tax expense. Income tax expense has been computed using expected future tax rates and giving effect to tax deductions and credits available, under current laws in effect as of December 31, 2023, and which relate to oil and gas producing activities. This information does not purport to present the fair market value of the Company’s oil and gas assets, but does present a standardized disclosure concerning possible future net cash flows that would result under the assumptions used.
