Notes to Consolidated Condensed Financial Statements | Occidental Petroleum Corporation and Subsidiaries

NOTE 1 - GENERAL

NATURE OF OPERATIONS
Occidental conducts its operations through various subsidiaries and affiliates. Occidental has made its disclosures in accordance with United States generally accepted accounting principles as they apply to interim reporting, and condensed or omitted, as permitted by the U.S. Securities and Exchange Commission’s rules and regulations, certain information and disclosures normally included in Consolidated Financial Statements and the notes thereto. These unaudited Consolidated Condensed Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and the notes thereto in the 2023 Form 10-K.
In the opinion of Occidental’s management, the accompanying unaudited Consolidated Condensed Financial Statements in this report reflect all adjustments (consisting of normal recurring adjustments) that are necessary to fairly present Occidental’s results of operations and cash flows for the three months ended March 31, 2024 and 2023 and Occidental’s financial position as of March 31, 2024 and December 31, 2023. The income and cash flows for the periods ended March 31, 2024 and 2023 are not necessarily indicative of the income or cash flows to be expected for the full year.
CASH EQUIVALENTS AND RESTRICTED CASH EQUIVALENTS
Occidental considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents or restricted cash equivalents. The cash equivalents and restricted cash equivalents balances for the periods presented include investments in government money market funds in which the carrying value approximates fair value.
The following table provides a reconciliation of cash, cash equivalents, restricted cash and restricted cash equivalents as reported in the Consolidated Condensed Statements of Cash Flows as of March 31, 2024 and 2023:

millions | 2024 | 2023
Cash and cash equivalents | $ | 1,272 |  | $ | 1,165 |
Restricted cash and restricted cash equivalents included in other current assets | 44 |  | 36 |
Restricted cash and restricted cash equivalents included in other long-term assets, net | 17 |  | 17 |
Cash, cash equivalents, restricted cash and restricted cash equivalents | $ | 1,333 |  | $ | 1,218 |

SUPPLEMENTAL CASH FLOW INFORMATION
The following table represents U.S. federal, state and international income taxes paid and interest paid during the three months ended March 31, 2024 and 2023, respectively:

millions | 2024 | 2023
Income tax payments | $ | 152 |  | $ | 164 |
Interest paid (a) | $ | 395 |  | $ | 410 |

(a) Net of capitalized interest of $33 million and $19 million for the three months ended March 31, 2024 and 2023, respectively.
WES INVESTMENT
WES is a publicly traded limited partnership with its limited partner units traded on the NYSE under the ticker symbol "WES". As of March 31, 2024, Occidental owned all of the 2.3% non-voting general partner interest, 48.7% of the WES limited partner units, and a 2% non-voting limited partner interest in WES Operating, a subsidiary of WES. As of March 31, 2024, Occidental's combined share of net income from WES and its subsidiaries was 50.9%.
NON-CONTROLLING INTEREST
In 2023, Occidental and BlackRock formed a joint venture for the continued development of the first commercial scale direct air capture facility using Carbon Engineering technology. The joint venture is a VIE and Occidental consolidates the VIE as it is the primary beneficiary. BlackRock’s investment is accounted for as an NCI. Each party has committed to make additional investments towards the completion of the direct air capture facility in Ector County, Texas, with BlackRock committed to invest up to $550 million. In addition, Occidental has entered into agreements with the joint venture related to
8

project management, operations and maintenance and carbon removal offtake. Occidental may incur additional payments if certain construction and operational thresholds are not met.
Occidental may call the NCI on June 30, 2025 or earlier if the plant does not achieve commercial operations or ceases and permanently discontinues operations. Dividends from the joint venture will be distributed preferentially to the NCI up to a return threshold, then preferentially to Occidental thereafter. The NCI receives preferential distributions in liquidation.
Because distributions from the joint venture will not be consistent over time, or with the initial investments or ownership interest, Occidental has determined that the appropriate methodology for attributing income and loss from the joint venture is the HLBV method. Under the HLBV method, the amounts of income and loss attributed to the NCI in the consolidated statements of operations reflect changes in the amounts the NCI would hypothetically receive at each balance sheet date if the joint venture was liquidated. As of March 31, 2024, the VIE’s assets were comprised of $432 million construction in progress.

NOTE 2 - REVENUE

Revenue from customers is recognized when obligations under the terms of a contract with customers are satisfied; this generally occurs with the delivery of oil, NGL, gas, chemicals or services, such as transportation. As of March 31, 2024, trade receivables, net of $3.3 billion represent rights to payment for which Occidental has satisfied its obligations under a contract and its right to payment is conditioned only on the passage of time.
The following table shows a reconciliation of revenue from customers to total net sales for the three months ended March 31, 2024 and 2023:

| Three months ended March 31, |
millions | 2024 | 2023 |  |
Revenue from customers | $ | 6,731 |  | $ | 7,115 |  |  |
All other revenues (a) | (756) |  | 110 |  |  |

(a) Includes marketing and chemical other revenues.

DEBT ACTIVITY
In February 2024, Occidental entered into a Third Amended and Restated Credit Agreement for the RCF retaining its $4.0 billion borrowing capacity, but extending the maturity date to June 30, 2028. Occidental has $1.1 billion of debt maturities due in the next 12 months.
In the first quarter of 2023, Occidental used cash on hand to repay $22 million of its 8.750% medium-term notes upon maturity.
FAIR VALUE OF DEBT
The estimated fair value of Occidental’s debt as of March 31, 2024 and December 31, 2023, substantially all of which was classified as Level 1, was approximately $18.0 billion.

NOTE 5 - ACQUISITIONS

CROWNROCK ACQUISITION
In December 2023, Occidental entered into an agreement to purchase CrownRock L.P. for total consideration of approximately $12.0 billion. If regulatory approval is received, Occidental intends to finance the purchase with the issuance with up to $9.1 billion of new debt, the issuance of approximately 29.6 million shares of common equity and the assumption of CrownRock’s $1.2 billion of existing debt. The amount of new debt issued will be decreased by any available cash and excess cash flow generated by CrownRock from January 1, 2024 to close. The agreement is subject to customary closing conditions and the receipt of regulatory approval, including the expiration or termination of the waiting period (and any extensions thereof) under the HSR Act.
In connection with the CrownRock Acquisition, Occidental has secured a fully-committed $5.3 billion bridge loan facility, a $2.0 billion 364-day term loan, and a $2.7 billion two-year term loan. No amounts were drawn as of March 31, 2024 under any of the aforementioned acquisition financings. Proceeds from the loans must be used to fund all or a portion of the CrownRock Acquisition. Financing costs related to the CrownRock Acquisition of $44 million were included in interest and debt expense, net, for the three months ended March 31, 2024.
On January 19, 2024, Occidental and the Sellers each received a Second Request from the Federal Trade Commission in connection with its review of the CrownRock Acquisition. A Second Request extends the waiting period imposed by the HSR Act until 30 days after each of Occidental and the Sellers have substantially complied with the Second Request issued to them, unless that period is extended voluntarily by Occidental and the Sellers or terminated sooner by the Federal Trade Commission. The response to the Second Request is ongoing, and Occidental and the Sellers continue to work constructively with the Federal Trade Commission in its review of the CrownRock Acquisition.

NOTE 6 - DERIVATIVES

OBJECTIVE AND STRATEGY
Occidental uses a variety of derivative financial instruments and physical contracts to manage its exposure to commodity price fluctuations and transportation commitments and to fix margins on the future sale of stored commodity volumes. Derivatives are carried at fair value and on a net basis when a legal right of offset exists with the same counterparty. Occidental may occasionally use a variety of derivative financial instruments to manage its exposure to foreign currency fluctuations and interest rate risks. Occidental also enters into derivative financial instruments for trading purposes.
Occidental may elect normal purchases and normal sales exclusions when physically delivered commodities are purchased or sold to a customer. Occidental occasionally applies cash flow hedge accounting treatment to derivative financial instruments to lock in margins on the forecasted sales of its natural gas storage volumes, and at times for other strategies, such as to lock in rates on debt issuances. The value of cash flow hedges is insignificant for all periods presented. As of March 31, 2024, Occidental’s marketing derivatives are not designated as hedges.
MARKETING DERIVATIVES
Occidental's marketing derivative instruments are short-duration physical and financial forward contracts. As of March 31, 2024, the weighted-average settlement price of these forward contracts was $80.26 per barrel and $1.51 per Mcf for crude oil and natural gas, respectively. The weighted-average settlement price was $76.36 per barrel and $2.62 per Mcf for crude oil and natural gas, respectively, as of December 31, 2023. Derivative instruments that are not designated as hedging instruments are required to be recorded on the balance sheet at fair value. Changes in fair value will impact Occidental’s earnings through mark-to-market adjustments until the physical commodity is delivered or the financial instrument is settled. Net gains and losses associated with marketing derivative instruments are recognized currently in net sales.
The following table summarizes net short volumes associated with the outstanding marketing commodity derivatives as of:

long (short) | March 31, 2024 | December 31, 2023
Oil commodity contracts |  |
Volume (MMbbl) | (27) |  | (20) |

(a)These amounts do not include collateral. Occidental netted $45 million of collateral deposited with brokers against derivatives liabilities as of March 31, 2024 and netted $42 million of collateral received with brokers against derivative assets as of December 31, 2023.
GAINS AND LOSSES ON DERIVATIVES
The following table presents net losses related to Occidental's derivative instruments and the location on the Consolidated Condensed Statements of Operations.

Income Statement Classification | 2024 | 2023 |  |
Marketing Derivatives (included in Net sales) | $ | (238) |  | $ | (6) |  |  |

CREDIT RISK
The majority of Occidental’s counterparty credit risk is related to the physical delivery of energy commodities to its customers and their potential inability to meet their settlement commitments. Occidental manages credit risk by selecting counterparties that it believes to be financially strong, by entering into netting arrangements with counterparties and by requiring collateral or other credit risk mitigants, as appropriate. Occidental actively evaluates the creditworthiness of its counterparties, assigns appropriate credit limits and monitors credit exposures against those assigned limits. Occidental also enters into futures contracts through regulated exchanges with select clearinghouses and brokers, which are subject to minimal credit risk, if any.

NOTE 7 - INCOME TAXES

The following table summarizes components of income tax expense:

| Three months ended March 31, |
millions | 2024 | 2023 |  |
Income before income taxes | $ | 1,010 | $ | 1,734 |  |

Net income | $ | 706 | $ | 1,263 |  |
Worldwide effective tax rate | 30 | % | 27 | % |  |

The 30% and 27% worldwide effective tax rates for the three months ended March 31, 2024 and three months ended March 31, 2023, respectively, are primarily driven by Occidental's jurisdictional mix of income. U.S. income is taxed at a U.S. federal statutory rate of 21%, while international income is subject to tax at statutory rates as high as 55%.
INFLATION REDUCTION ACT AND PILLAR TWO
In August 2022, Congress passed the IRA that contains, among other provisions, a corporate book minimum tax on financial statement income, an excise tax on stock buybacks, a methane emissions charge and certain tax incentives related to climate change and clean energy. Occidental is currently evaluating the guidance and proposed regulations. The ultimate impact of the IRA to Occidental will depend on a number of factors including future commodity prices, interpretations and assumptions as well as additional regulatory guidance.
Approximately 140 countries have agreed to a statement in support of the OECD Pillar Two initiative that proposes a 15% global minimum tax on a jurisdiction-by-jurisdiction basis. A number of countries, including European Union member states, the United Kingdom, and Canada have enacted or are in the process of enacting legislation to be effective in 2024, with widespread implementation of a global minimum tax expected by 2025. As the legislation becomes effective in countries in which Occidental operates, its cash tax could increase, and its effective tax rate could be negatively impacted. Occidental will continue to monitor proposed legislation and guidance issued by both the OECD as well as the jurisdictions in which it operates to assess the impact on its tax position. We do not expect the provisions effective in 2024 to have a materially adverse impact on our results of operations, financial position, or cash flows.

NOTE 8 - ENVIRONMENTAL LIABILITIES AND EXPENDITURES

Occidental and its subsidiaries and their respective operations are subject to stringent federal, regional, state, provincial, tribal, local and international laws and regulations related to improving or maintaining environmental quality. The laws that require or address environmental remediation, including CERCLA and similar federal, regional, state, provincial, tribal, local and international laws, may apply retroactively and regardless of fault, the legality of the original activities or the current ownership or control of sites. Occidental or certain of its subsidiaries participate in or actively monitor a range of remedial activities and government or private proceedings under these laws with respect to alleged past practices at Third-Party, Currently Operated, and Closed or Non-Operated Sites. Remedial activities may include one or more of the following: investigation involving sampling, modeling, risk assessment or monitoring; clean-up measures including removal, treatment or disposal; or operation and maintenance of remedial systems. The environmental proceedings seek funding or performance of remediation and, in some cases, compensation for alleged property damage, natural resource damages, punitive damages, civil penalties, injunctive relief and government oversight costs.
ENVIRONMENTAL REMEDIATION
As of March 31, 2024, certain Occidental subsidiaries participated in or monitored remedial activities or proceedings at 159 sites. The following table presents the current and non-current environmental remediation liabilities of such subsidiaries on a consolidated basis as of March 31, 2024. The current portion of $131 million is included in accrued liabilities and the remainder of $870 million is included in deferred credits and other liabilities - environmental remediation liabilities.
These environmental remediation sites are grouped into NPL Sites and the following three categories of non-NPL Sites—Third-Party Sites, Currently Operated Sites and Closed or Non-Operated Sites.

millions, except number of sites | Number of Sites | Remediation Balance
NPL Sites | 32 |  | $ | 432 |
Third-Party Sites | 64 |  | 220 |
Currently Operated Sites | 12 |  | 96 |
Closed or Non-Operated Sites | 51 |  | 253 |
Total | 159 |  | $ | 1,001 |

As of March 31, 2024, environmental remediation liabilities of Occidental subsidiaries exceeded $10 million each at 18 of the 159 sites described above, and 93 of the sites had liabilities from $0 to $1 million each. Based on current estimates, Occidental expects its subsidiaries to expend funds corresponding to approximately 45% of the period-end remediation balance over the next three to four years with the remainder over the subsequent 10 or more years.
Occidental believes its range of reasonably possible additional losses of its subsidiaries beyond those amounts currently recorded for environmental remediation for the 159 environmental sites in the table above could be up to $2.6 billion. The status of Occidental's involvement with the sites and related significant assumptions, including those sites indemnified by Maxus, has not changed materially since December 31, 2023.
MAXUS ENVIRONMENTAL SITES
A significant portion of aggregate estimates of environmental remediation liabilities and reasonably possible additional losses described above relates to the former DSCC. When OxyChem acquired DSCC in 1986, Maxus agreed to indemnify OxyChem for a number of environmental sites, including the DASS. In June 2016, Maxus and several affiliated companies filed for Chapter 11 bankruptcy in the U.S. Bankruptcy Court for the District of Delaware. Prior to filing for bankruptcy, Maxus defended and indemnified OxyChem in connection with remediation costs and other liabilities associated with the sites subject to the indemnity. In 2023, OxyChem recovered on its remaining claims for indemnified costs from the proceeds of litigation brought by the Maxus Liquidating Trust.
DIAMOND ALKALI SUPERFUND SITE
The EPA has organized the DASS into four Operable Units (OUs) for evaluating, selecting and implementing remediation under CERCLA. OxyChem’s current activities in each OU are summarized below, many of which are performed on OxyChem’s behalf by Glenn Springs Holdings, Inc.
OU1 – The Former Diamond Alkali Plant at 80-120 Lister Avenue in Newark: Maxus and its affiliates implemented an interim remedy of OU1 pursuant to a 1990 Consent Decree, for which OxyChem currently performs maintenance and monitoring. The EPA conducts periodic evaluations of the interim remedy for OU1.
17

OU2 – The Lower 8.3 Miles of the Lower Passaic River: In March 2016, the EPA issued a ROD specifying remedial actions required for OU2. During the third quarter of 2016, and following Maxus’s bankruptcy filing, OxyChem and the EPA entered into an AOC to complete the design of the remedy selected in the ROD. At that time, the EPA sent notice letters to approximately 100 parties notifying them that they were potentially responsible to pay the costs to implement the remedy in OU2 and announced that it would pursue similar agreements with other potentially responsible parties. In June 2018, OxyChem filed a complaint under CERCLA in U.S. District Court for the District of New Jersey against numerous potentially responsible parties seeking contribution and cost recovery of amounts incurred or to be incurred to comply with the AOC and the OU2 ROD, or to perform other remediation activities related to the DASS (2018 Contribution Action). The District Court has not adjudicated OxyChem’s relative share of responsibility for those costs. The EPA has estimated the cost to remediate OU2 to be approximately $1.4 billion.
OU3 – Newark Bay Study Area, including Newark Bay and Portions of the Hackensack River, Arthur Kill, and Kill van Kull: Maxus and its affiliates initiated a remedial investigation and feasibility study of OU3 pursuant to a 2004 AOC which was amended in 2010. OxyChem is currently performing feasibility study activities in OU3. In September 2022, the EPA listed the Lower Hackensack River (LHR) on the NPL, and this newly listed site comprises several existing NPL sites along a portion of that river that flows into OU3. In January 2024, EPA sent a general notice letter requesting that OxyChem and four other entities coordinate certain investigation activities at the LHR site.
OU4 – The 17-mile Lower Passaic River Study Area, comprising OU2 and the Upper 9 Miles of the Lower Passaic River: In September 2021, the EPA issued a ROD selecting an interim remedy for the portion of OU4 that excludes OU2 and is located upstream from the Lister Avenue Plant site for which OxyChem inherited legal responsibility. The EPA has estimated the cost to remediate OU4 to be approximately $440 million. At this time, OxyChem's role or responsibilities under the OU4 ROD, and those of other potentially responsible parties, have not been adjudicated. To provide continued, efficient remediation progress, in January 2022, OxyChem offered to design and implement the interim remedy for OU4 subject to certain conditions, including a condition that the EPA would not seek to bar OxyChem’s right to seek contribution or cost recovery from any other parties that are potentially responsible to pay for the OU4 interim remedy. In March 2022, the EPA sent a notice letter to OxyChem and other parties requesting good faith offers to implement the selected remedies at OU2 and OU4. OxyChem submitted a good faith offer in June 2022, reaffirming the offer to design the remedy for OU4 and offering to enter into additional sequential agreements to remediate OU2 and OU4, subject to similar conditions, including that the EPA not seek to bar OxyChem from pursuing contribution or cost recovery from other responsible parties. The EPA did not accept OxyChem's June 2022 offer. In March 2023, the EPA issued a Unilateral Administrative Order (OU4 UAO) in which it directed and ordered OxyChem to design the EPA’s selected interim remedy for OU4 and to provide approximately $93 million in financial assurance to secure its performance. Subject to all its defenses, OxyChem is designing the interim remedy in compliance with the OU4 UAO. As a result of OxyChem incurring costs to implement the OU4 UAO, and the EPA's proposal described below to bar OxyChem's contribution claims against various parties, including those asserted in the 2018 Contribution Action, OxyChem filed a cost recovery action under CERCLA in March 2023 in the District Court against multiple parties (2023 Cost Recovery Action).
Natural Resource Trustees – In addition to the activities of the EPA and OxyChem in the OUs described above, federal and state natural resource trustees are assessing natural resources in the Lower Passaic River and Greater Newark Bay to evaluate potential claims for natural resource damages.
ALDEN LEEDS LITIGATION
In December 2022, the EPA and the DOJ filed a proposed Consent Decree in the Alden Leeds litigation seeking court approval to settle with 85 parties for a total of $150 million which OxyChem believes is based on an unauthorized, flawed and disproportionate allocation of responsibility, release the settling companies from liability to the United States for remediation costs in DASS OU2 and OU4 and bar OxyChem from pursuing contribution against those parties for remediation costs OxyChem had incurred or may incur in the future to design and implement the remedies in OU2 and OU4, including claims OxyChem asserted in the 2018 Contribution Action. The proposed settlement does not address the liability of entities that were excluded from the settlement for the DASS, including OU2, OU3, OU4 or natural resource damages, or the liability of any settling party with respect to OU3 or natural resource damages. The proposed settlement was subject to a public comment period that closed in March 2023. In January 2024, the DOJ filed a proposed Amended Consent Decree in which it excluded three companies from the proposed settlement, among other changes, and a motion to approve the Amended Consent Decree.
OxyChem believes the proposed settlement and Amended Consent Decree rely, improperly, on an allocation report prepared by an EPA contractor in which the contractor purported to assign a disproportionate share of the responsibility for remediation costs in OU2 and OU4 to OxyChem. OxyChem also believes that process was unreasonably limited in scope and unreliably based on voluntary reporting by the settling parties, instead of sworn evidence, publicly available sampling results and historical documents reflecting the operating history and disposal practices of the 82 parties that the EPA proposes to release in this settlement.
OxyChem intends to challenge vigorously the proposed settlement and Amended Consent Decree, as well as the allocation report and process upon which they are based, and to seek contribution and cost recovery from other potentially
18

responsible parties for remediation costs it has incurred or may incur at the DASS. OxyChem filed its response to the motion to approve the Amended Consent Decree on April 1, 2024. Replies to OxyChem's filing are due in May 2024.
OxyChem does not know when the District Court will rule on the DOJ’s motion to approve the Amended Consent Decree. If the Amended Consent Decree is approved by the District Court and not overturned on appeal, then, notwithstanding OxyChem’s vigorous, good faith effort to contest the settlement proposed in the Alden Leeds litigation, the EPA could attempt to compel OxyChem to bear substantially all the estimated cost to design and implement the OU2 and OU4 remedies. Such a result could have a material adverse impact on OxyChem and Occidental’s consolidated results of operations in the period recorded.
While the remedies for OU2 and OU4 are expected to take over ten years to complete, the EPA may seek to require OxyChem to provide additional financial assurance. In the OU4 UAO, the EPA directed OxyChem to post financial assurance in the amount of approximately $93 million. Subject to all defenses, OxyChem has complied with this directive. The amount of any additional financial assurance is not subject to estimation at this time. It is uncertain when or to what extent the EPA may take action to compel OxyChem to perform further remediation in OU2 or OU4 or the amount of financial assurance the EPA may attempt to require OxyChem to post. For further information on the Alden Leeds litigation, see Note 9 - Lawsuits, Claims, Commitments and Contingencies.
OTHER INFORMATION
For the DASS, OxyChem has accrued a reserve relating to its estimated allocable share of the costs to perform the maintenance and monitoring required in the OU1 Consent Decree, the design and implementation of remedies selected in the OU2 ROD and AOC and the OU4 ROD and OU4 UAO, and the remedial investigation and feasibility study required in OU3.
OxyChem’s accrued environmental remediation reserve does not reflect the potential for additional remediation costs or natural resource damages for the DASS that OxyChem believes are not reasonably estimable. OxyChem’s ultimate liability at the DASS may be higher or lower than the reserved amount and the reasonably possible additional losses, and is subject to final design plans, further action by the EPA and natural resource trustees, and the resolution of OxyChem's allocable share with other potentially responsible parties, among other factors.
OxyChem continues to evaluate the estimated costs currently recorded for remediation at the DASS as well as the range of reasonably possible additional losses beyond those amounts currently recorded. Given the complexity and extent of the remediation efforts, estimates of the remediation costs may increase or decrease over time as new information becomes available.

NOTE 9 - LAWSUITS, CLAIMS, COMMITMENTS AND CONTINGENCIES

LEGAL MATTERS
Occidental or certain of its subsidiaries are involved, in the normal course of business, in lawsuits, claims and other legal proceedings that seek, among other things, compensation for alleged personal injury, breach of contract, property damage or other losses, punitive damages, civil penalties, or injunctive or declaratory relief. Occidental or certain of its subsidiaries also are involved in proceedings under CERCLA and similar federal, regional, state, provincial, tribal, local and international environmental laws. These environmental proceedings seek funding or performance of remediation and, in some cases, compensation for alleged property damage, natural resource damages, punitive damages, civil penalties, injunctive relief and government oversight costs. Usually Occidental or such subsidiaries are among many companies in these environmental proceedings and have to date been successful in sharing remediation costs with other financially sound companies. Further, some lawsuits, claims and legal proceedings involve acquired or disposed assets with respect to which a third party or Occidental or its subsidiary retains liability or indemnifies the other party for conditions that existed prior to the transaction.
In accordance with applicable accounting guidance, Occidental or its subsidiaries accrue reserves for outstanding lawsuits, claims and proceedings when it is probable that a liability has been incurred and the liability can be reasonably estimated. Reserves for matters, other than for the arbitration award (disclosed below), tax matters or environmental remediation, that satisfy these criteria as of March 31, 2024 and 2023 were not material to Occidental’s Consolidated Condensed Balance Sheets.
If unfavorable outcomes of these matters were to occur, future results of operations or cash flows for any particular quarterly or annual period could be materially adversely affected. Occidental’s estimates are based on information known about the legal matters and its experience in contesting, litigating and settling similar matters. Occidental will reassess the probability and estimability of contingent losses as new information becomes available.
19

ANDES ARBITRATION
In 2016, Occidental received payments from the Republic of Ecuador of approximately $1.0 billion pursuant to a November 2015 arbitration award for Ecuador’s 2006 expropriation of Occidental’s Participation Contract for Block 15. The awarded amount represented a recovery of Occidental's 60% of the value of Block 15. In 2017, Andes commenced an arbitration against OEPC, claiming it is entitled to a 40% share of the judgment amount obtained by Occidental. Occidental believes that Andes is not entitled to any of the amounts paid under the 2015 arbitration award because Occidental’s recovery was limited to Occidental’s own 60% economic interest in the block. In March 2021, the arbitration tribunal issued an award in favor of Andes and against OEPC in the amount of $391 million plus interest. In June 2023, the U.S. Court of Appeals for the Second Circuit confirmed the District Court's ruling with respect to the arbitration award but overturned the District Court's decision to add prejudgment interest in the amount of $166 million, ordering the District Court to recalculate the interest amount. Simultaneously, OEPC sought review of the Second Circuit ruling in the U.S. Supreme Court.
During 2021, OEPC commenced an arbitration against Andes to recover significant additional claims, which were not addressed by the prior arbitration tribunal, relating to Andes' 40% share of costs, liabilities, losses, and expenses due under the farmout agreement and joint operating agreement to which Andes and OEPC are parties. In July 2023, a majority of the arbitration tribunal declined to award any costs to OEPC based upon the doctrine of res judicata. One arbitrator dissented, noting that the prior arbitration panel expressly noted that it was not ruling on the types of claims asserted by OEPC. Andes sought to confirm this award in New York federal district court, and OEPC asked to vacate it because, among other reasons, OEPC believed there were fundamental legal errors embodied in the award.
During the pendency of the appeal of the 2021 Andes Award, Andes filed state court claims in New York and Delaware against OEPC, Occidental Petroleum Corporation (OPC) and OXY USA to attempt to recover on its judgment against OEPC. Andes also filed a turnover application against OPC in New York federal district court. The New York state court dismissed Andes’ action against OPC with prejudice in March 2023. Andes appealed. Both OXY USA and Andes filed motions for summary judgment in the Delaware state court action. The Delaware state court heard argument on these motions in November 2023. The Delaware state court action and the New York federal district court action were pending at the end of Q1.
On April 5, 2024, Andes and the Occidental entities named in the pending actions executed a confidential final settlement in which the parties agreed to dismiss all pending legal actions. The settlement resulted in a gain of $182 million, net of taxes, in discontinued operations.
ALDEN LEEDS AND OTHER LITIGATION
As described in Note 8 – Environmental Liabilities and Expenditures, OxyChem intends to challenge vigorously the proposed settlement and Amended Consent Decree in the Alden Leeds litigation, as well as the allocation report and process upon which they are based. In the 2018 Contribution Action and 2023 Cost Recovery Action, OxyChem also intends to defend and prosecute vigorously its right to seek contribution and cost recovery from all potentially responsible parties to pay remediation costs in the DASS and to seek a judicial allocation of responsibility under CERCLA. The 2018 Contribution Action and the 2023 Cost Recovery Action are currently stayed pending the outcome of the Alden Leeds litigation. As the Alden Leeds litigation is in its early stages, OxyChem is unable to estimate the timing of the District Court’s decision, its outcome, or the outcome of any appeals from the District Court’s decision.
TAX MATTERS AND DISPUTES
During the course of its operations, Occidental is subject to audit by tax authorities for varying periods in various federal, state, local and international tax jurisdictions. Tax years through 2021 for U.S. federal income tax purposes have been audited by the IRS pursuant to its Compliance Assurance Program and subsequent taxable years are currently under review. Tax years through 2018 have been audited for state income tax purposes. There are no outstanding significant audit matters in international jurisdictions. During the course of tax audits, disputes have arisen and other disputes may arise as to facts and matters of law.
For Anadarko, its taxable years through 2014 and tax year 2016 for U.S. federal tax purposes have been audited and closed by the IRS. Tax years 2015 and 2017 through 2019 have been audited by the IRS but remain open pending the outcome of the Tronox U.S. Tax court litigation discussed below. Tax years through 2010 have been audited for state income tax purposes. There is one outstanding significant tax matter in an international jurisdiction related to a discontinued operation. As stated above, during the course of tax audits, disputes have arisen and other disputes may arise as to facts and matters of law.
Other than the dispute discussed below, Occidental believes that the resolution of these outstanding tax disputes would not have a material adverse effect on its consolidated financial position or results of operations.
Anadarko received an $881 million tentative refund in 2016 related to its $5.2 billion Tronox Adversary Proceeding settlement payment in 2015. In September 2018, Anadarko received a statutory notice of deficiency from the IRS disallowing the net operating loss carryback and rejecting Anadarko’s refund claim. As a result, Anadarko filed a petition with the U.S. Tax Court to dispute the disallowances in November 2018. Trial was held in May 2023. The parties filed simultaneous post-
20

trial briefs on September 1, 2023 and filed reply briefs on December 7, 2023. Closing arguments are scheduled for May 2024. An opinion by the Tax Court could be issued at any time. If any tax liability is due as a result of the Tax Court’s opinion, it must be fully bonded or paid in full within 90 days of the entry of decision by the Tax Court. If an appeal is not pursued by Anadarko, any resulting tax deficiency will be assessed by the IRS and would be due within 30 days of receiving a formal notice of tax assessment.
In accordance with ASC 740’s guidance on the accounting for uncertain tax positions, Occidental has recorded no tax benefit on the tentative cash tax refund of $881 million. Additionally, Occidental has recorded no tax benefit on approximately $500 million of additional cash tax benefits realized from the utilization of tax attributes generated as a result of the deduction of the $5.2 billion Tronox Adversary Proceeding settlement payment in 2015. As a result, should Occidental not ultimately prevail on the issue, there would be no additional tax expense recorded relative to this position for financial statement purposes other than future interest. However, in that event, as of March 31, 2024, Occidental would be required to repay approximately $1.4 billion in federal taxes, $28 million in state taxes and accrued interest of $622 million. A liability for the taxes and interest is included in deferred credits and other liabilities - other.
INDEMNITIES TO THIRD PARTIES
Occidental, its subsidiaries, or both, have indemnified various parties against specified liabilities those parties might incur in the future in connection with purchases and other transactions that they have entered into with Occidental or its subsidiaries. These indemnities usually are contingent upon the other party incurring liabilities that reach specified thresholds. As of March 31, 2024, Occidental is not aware of circumstances that it believes would reasonably be expected to lead to indemnity claims that would result in payments materially in excess of reserves.

All statements other than statements of historical fact are “forward-looking statements” for purposes of federal and state securities laws, including, but not limited to: any projections of earnings, revenue or other financial items or future financial position or sources of financing; any statements of the plans, strategies and objectives of management for future operations or business strategy; any statements regarding future economic conditions or performance; any statements of belief; and any statements of assumptions underlying any of the foregoing. Words such as “estimate,” “project,” “predict,” “will,” “would,” “should,” “could,” “may,” “might,” “anticipate,” “plan,” “intend,” “believe,” “expect,” “aim,” “goal,” “target,” “objective,” "commit," "advance," “likely” or similar expressions that convey the prospective nature of events or outcomes are generally indicative of forward-looking statements. You should not place undue reliance on these forward-looking statements, which speak only as of the date of this report unless an earlier date is specified. Unless legally required, Occidental does not undertake any obligation to update, modify or withdraw any forward-looking statements as a result of new information, future events or otherwise.
Actual outcomes or results may differ from anticipated results, sometimes materially. Forward-looking and other statements regarding Occidental's sustainability efforts and aspirations are not an indication that these statements are necessarily material to investors or require disclosure in Occidental's filings with the SEC. In addition, historical, current and forward-looking sustainability-related statements may be based on standards for measuring progress that are still developing, internal controls and processes that continue to evolve and assumptions that are subject to change in the future, including future rulemaking. Factors that could cause results to differ from those projected or assumed in any forward-looking statement include, but are not limited to: general economic conditions, including slowdowns and recessions, domestically or internationally; Occidental’s indebtedness and other payment obligations, including the need to generate sufficient cash flows to fund operations; Occidental’s ability to successfully monetize select assets and repay or refinance debt and the impact of changes in Occidental’s credit ratings or future increases in interest rates; assumptions about energy markets; global and local commodity and commodity-futures pricing fluctuations and volatility; supply and demand considerations for, and the prices of, Occidental’s products and services; actions by OPEC and non-OPEC oil producing countries; the scope and duration of global or regional health pandemics or epidemics, and actions taken by government authorities and other third parties in connection therewith; results from operations and competitive conditions; future impairments of Occidental's proved and unproved oil and gas properties or equity investments, or write-downs of productive assets, causing charges to earnings; unexpected changes in costs; inflation, its impact on markets and economic activity and related monetary policy actions by governments in response to inflation; availability of capital resources, levels of capital expenditures and contractual obligations; the regulatory approval environment, including Occidental's ability to timely obtain or maintain permits or other government approvals, including those necessary for drilling and/or development projects; Occidental's ability to successfully complete, or any material delay of, field developments, expansion projects, capital expenditures, efficiency projects, acquisitions or divestitures, including the CrownRock Acquisition; risks associated with acquisitions, mergers and joint ventures, such as difficulties integrating businesses, uncertainty associated with financial projections, projected synergies, restructuring, increased costs and adverse tax consequences; uncertainties and liabilities associated with acquired and divested properties and businesses; uncertainties about the estimated quantities of oil, NGL and natural gas reserves; lower-than-expected production from development projects or acquisitions; Occidental’s ability to realize the anticipated benefits from prior or future streamlining actions to reduce fixed costs, simplify or improve processes and improve Occidental’s competitiveness; exploration, drilling and other operational risks; disruptions to, capacity constraints in, or other limitations on the pipeline systems that deliver Occidental’s oil and natural gas and other processing and transportation considerations; volatility in the securities, capital or credit markets, including capital market disruptions and instability of financial institutions; government actions, war (including the Russia-Ukraine war and conflicts in the Middle East) and political conditions and events; health, safety and environmental (HSE) risks, costs and liability under existing or future federal, regional, state, provincial, tribal, local and international HSE laws, regulations, and litigation (including related to climate change or remedial actions or assessments); legislative or regulatory changes, including changes relating to hydraulic fracturing or other oil and natural gas operations, retroactive royalty or production tax regimes and deep-water and onshore drilling and permitting regulations; Occidental's ability to recognize intended benefits from its business strategies and initiatives, such as Occidental's low-carbon ventures businesses or announced greenhouse gas emissions reduction targets or net-zero goals; potential liability resulting from pending or future litigation, government investigations and other proceedings; disruption or interruption of production or manufacturing or facility damage due to accidents, chemical releases, labor unrest, weather, power outages, natural disasters, cyber-attacks, terrorist acts or insurgent activity; the creditworthiness and performance of Occidental's counterparties, including financial institutions, operating partners and other parties; failure of risk management; Occidental’s ability to retain and hire key personnel; supply, transportation, and labor constraints; reorganization or restructuring of Occidental’s operations; changes in state, federal or international tax rates; and actions by third parties that are beyond Occidental's control.
Additional information concerning these and other factors that may cause Occidental’s results of operations and financial position to differ from expectations can be found in Occidental’s other filings with the SEC, including Occidental’s 2023 Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K.
24

CURRENT BUSINESS OUTLOOK

Occidental’s operations, financial condition, cash flows and levels of expenditures are highly dependent on oil prices and, to a lesser extent, NGL and natural gas prices, the Midland-to-Gulf-Coast oil spreads, chemical product prices and inflationary pressures in the macro-economic environment. The average WTI price per barrel for the three months ended March 31, 2024 was $76.96, compared to $78.32 for the three months ended December 31, 2023 and $76.13 for the three months ended March 31, 2023. Changes in prices could result in adjustments in capital investment levels and how such capital is allocated, which could impact production volumes. It is expected that the price of oil will be volatile for the foreseeable future given the current geopolitical risks, evolving macro-economic environment that impacts energy demand, future actions by OPEC and non-OPEC oil producing countries, the Russia-Ukraine war and the conflicts in the Middle East, and the Biden Administration's management of the U.S. Strategic Petroleum Reserve. Seasonality is not a primary driver of changes in Occidental's consolidated quarterly earnings during the year.
Occidental works to manage inflation impacts by capitalizing on operational efficiencies, proactive contract management and working closely with vendors to secure the supply of critical materials. As of March 31, 2024, substantially all of Occidental's outstanding debt was fixed rate.
2024 PRIORITIES
Occidental’s capital and operational priorities for 2024 are intended to maximize cash flow through focused investments in short and medium-cycle projects to enhance current year and future cash flows. Occidental intends to utilize future operating cash flows to:
■Maintain production base to preserve asset base integrity and longevity;
■Deliver a sustainable and growing dividend;
■Enhance its asset base with new investments in its cash-generative energy and chemical businesses as well as emerging low-carbon businesses;
■Advance technologies and business solutions to help drive a sustainable low-carbon future;
■Further reduce long-term financial leverage; and
■Strengthen Occidental’s U.S. onshore portfolio with premier Permian Basin assets through the CrownRock Acquisition, which is expected to be immediately cash flow accretive.
During the first three months of 2024, Occidental generated cash flow from operations of $2.0 billion and incurred capital expenditures of $1.8 billion.
DEBT
As of March 31, 2024, Occidental’s long-term debt was rated Baa3 by Moody’s Investors Service, BBB- by Fitch Ratings and BB+ by Standard and Poor’s. Occidental's credit rating was upgraded to investment grade by Moody's Investors Service in March 2023 and by Fitch Ratings in May 2023. Any downgrade in credit ratings could impact Occidental's ability to access capital markets and increase its cost of capital. In addition, Occidental or its subsidiaries may be requested, elect to provide or in some cases be required to provide collateral in the form of cash, letters of credit, surety bonds or other acceptable support as financial assurance of their performance and payment obligations under certain contractual arrangements, such as pipeline transportation contracts, oil and gas purchase contracts and certain derivative instruments; certain permits, including with respect to carbon capture, utilization and storage activities; and environmental remediation matters. In February 2024, Occidental entered into a Third Amended and Restated Credit Agreement for the RCF retaining its $4.0 billion borrowing capacity, but extending the maturity date to June 30, 2028. No amounts were drawn under the facility as of March 31, 2024. Occidental has $1.1 billion of debt maturities due in the next 12 months.
SHAREHOLDER RETURNS
During the three months ended March 31, 2024, Occidental declared dividends to common shareholders of $197 million or $0.22 per share.

Q1 2024 compared to Q4 2023
Net sales decreased for the three months ended March 31, 2024, compared to the three months ended December 31, 2023, primarily due to lower crude oil prices as well and lower domestic crude oil volumes in the oil and gas segment, largely due to a third-party shut-in of production in Eastern GOM, where production resumed in April 2024, and lower realized prices across most products in the chemical segment.
Purchased commodities decreased for the three months ended March 31, 2024, compared to the three months ended December 31, 2023, due to lower volumes and prices on third-party crude purchases as certain crude supply contracts expired in 2023 in the midstream and marketing segment.
The increase in income from discontinued operations, net of taxes for the three months ended March 31, 2024, compared to the three months ended December 31, 2023, resulted from a legal settlement related to the Andes Arbitration. For further information on the Andes Arbitration, see Note 9 - Lawsuits, Claims, Commitments and Contingencies.
Q1 2024 compared to Q1 2023
Net sales decreased for the three months ended March 31, 2024, compared to the same period in 2023, primarily due to lower worldwide NGL and domestic natural gas commodity prices in the oil and gas segment and lower domestic oil volumes in the oil and gas segment largely due to a third-party shut-in of production in Eastern GOM and lower realized caustic soda prices in the chemical segment. The decrease was partially offset by higher domestic oil commodity prices in the oil and gas segment and increased demand and lower ethylene and energy costs in the chemical segment.
Purchased commodities decreased for the three months ended March 31, 2024, compared to the same period in 2023, due to lower volumes on third-party crude purchases as certain crude supply contracts expired in 2023 in the midstream and marketing segment.
Other operating and non-operating expense increased for the three months ended March 31, 2024, compared to the same period in 2023, due to legal settlement costs and increases in compensation costs.
Income from equity investments and other increased for the three months ended March 31, 2024, compared to the same period in 2023, primarily due to gains on sales of assets recognized by WES, an equity method investee.
The increase in income from discontinued operations, net of taxes for the three months ended March 31, 2024, compared to the same period in 2023, resulted from a legal settlement related to the Andes Arbitration.

SEGMENT RESULTS OF OPERATIONS

SEGMENT RESULTS OF OPERATIONS
Occidental’s principal businesses consist of three reporting segments: oil and gas, chemical and midstream and marketing. The oil and gas segment explores for, develops and produces oil and condensate, NGL and natural gas. The chemical segment mainly manufactures and markets basic chemicals and vinyls. The midstream and marketing segment purchases, markets, gathers, processes, transports and stores oil (which includes condensate), NGL, natural gas, CO 2 and power. It also optimizes its transportation and storage capacity and invests in entities that conduct similar activities such as WES.
The midstream and marketing segment also includes Occidental's low-carbon ventures businesses. Occidental's low-carbon ventures businesses seek to leverage Occidental’s legacy of carbon management expertise to develop carbon capture, utilization and storage projects, including the commercialization of direct air capture technology, invest in other low-carbon technologies intended to reduce greenhouse gas emissions from Occidental's operations and strategically partner with other industries to help reduce their emissions.

Q1 2024 compared to Q4 2023
Oil and gas segment earnings were $1.2 billion for the three months ended March 31, 2024, compared with segment earnings of $1.6 billion for the three months ended December 31, 2023. Excluding the impact of items affecting comparability, the decrease in oil and gas segment results for the three months ended March 31, 2024, compared to the three months ended December 31, 2023, was primarily due to lower domestic crude oil volumes largely due to a third-party shut-in of production in Eastern GOM, where production resumed in April 2024, and lower crude oil and domestic natural gas commodity prices.
The decrease in average daily sales volumes of 55 Mboe/d for the three months ended March 31, 2024, compared to the three months ended December 31, 2023, was primarily due to a third-party shut-in of production in Eastern GOM.
Q1 2024 compared to Q1 2023
Oil and gas segment earnings were $1.2 billion for the three months ended March 31, 2024, compared to $1.6 billion for the three months ended March 31, 2023. Excluding the impact of items affecting comparability, the decrease in oil and gas segment results for the three months ended March 31, 2024, compared to the three months ended March 31, 2023, was primarily due to lower domestic crude oil volumes largely due to a third-party shut-in of production in Eastern GOM, and lower natural gas and NGL commodity prices.
The decrease in average daily sales volumes of 39 Mboe/d for the three months ended March 31, 2024, compared to the three months ended March 31, 2023, was primarily due to a third-party shut-in of production in Eastern GOM.

CHEMICAL SEGMENT
Q1 2024 compared to Q4 2023
Chemical segment earnings remained consistent, with income of $254 million for the three months ended March 31, 2024, compared to income of $250 million for the three months ended December 31, 2023.
Q1 2024 compared to Q1 2023
Chemical segment earnings for the three months ended March 31, 2024 were $254 million, compared to $472 million for the three months ended March 31, 2023. The decrease in segment earnings was due primarily to lower caustic soda realized prices, partially offset by improved product demand and lower ethylene and energy costs.
31

MIDSTREAM AND MARKETING SEGMENT
Q1 2024 compared to Q4 2023
Midstream and marketing segment losses for the three months ended March 31, 2024 were $33 million, compared to segment earnings of $182 million for the three months ended December 31, 2023. Excluding the impact of items affecting comparability, midstream and marketing first quarter results increased due to higher crude margins related to the timing impact of crude sales, offset by higher losses from equity method investees and higher expenses due to the increase in activities in the low-carbon ventures businesses.
Q1 2024 compared to Q1 2023
Midstream and marketing segment losses for the three months ended March 31, 2024 were $33 million, compared to segment earnings of $2 million for the three months ended March 31, 2023. Excluding the impact of items affecting comparability, the decrease in midstream and marketing first quarter results reflected lower winter weather activity in the Rockies compared to prior year, higher losses from equity method investees and higher expenses due to the increase in activities in the low-carbon ventures businesses, partially offset by higher equity investee income from WES.

INCOME TAXES

The following table sets forth the calculation of the worldwide effective tax rate for income:

| Three months ended
millions, except percentages | March 31, 2024 | December 31, 2023 |  |  | March 31, 2023
Income before income taxes | $ | 1,010 |  | $ | 1,559 |  |  |  | $ | 1,734 |
Income tax expense |  |  |  |  |
Domestic - federal and state | (172) |  | (150) |  |  |  | (300) |
International | (132) |  | (211) |  |  |  | (171) |
Total income tax expense | (304) |  | (361) |  |  |  | (471) |
Net income | $ | 706 |  | $ | 1,198 |  |  |  | $ | 1,263 |
Worldwide effective tax rate | 30 | % | 23 | % |  |  | 27 | %

Occidental estimates its annual effective income tax rate in recording its quarterly provision for income taxes in the various jurisdictions in which Occidental operates, adjusted for certain discrete items. Each quarter, Occidental updates these rates and records a cumulative adjustment to its income taxes by applying the rates to the pre-tax income excluding certain discrete items. Occidental’s quarterly estimate of its effective tax rates can vary significantly based on various forecasted items, including future commodity prices, capital expenditures, expenses for which tax benefits are not recognized and the geographic mix of pre-tax income and losses.
The worldwide effective tax rates for the periods presented in the table above are primarily driven by Occidental's jurisdictional mix of income. U.S. income is taxed at a U.S. federal statutory rate of 21%, while international income is subject to tax at statutory rates as high as 55%.
INFLATION REDUCTION ACT AND PILLAR TWO

LIQUIDITY AND CAPITAL RESOURCES

SOURCES AND USES OF CASH
As of March 31, 2024, Occidental's sources of liquidity included $1.3 billion o f cash and cash equivalents, $4.0 billion of borrowing capacity under its RCF, which matures on June 30, 2028, and up to $600 million of available borrowing capacity on its receivables securitization facility which matures in December 2024. These amounts exclude CrownRock Acquisition financing discussed below. There were no borrowings outstanding on Occidental's RCF or receivables securitization facility as of March 31, 2024.
Operating cash flow was $2.0 billion for the three months ended March 31, 2024, compared to $2.9 billion for the three months ended March 31, 2023. The decrease in operating cash flow from continuing operations was primarily due to lower
32

domestic sales volumes largely due to a third-party shut-in of production in Eastern GOM, where production resumed in April 2024, and lower natural gas and NGL commodity prices.
Occidental’s net cash used by investing activities was $1.8 billion for the three months ended March 31, 2024, compared to $1.6 billion for the three months ended March 31, 2023. Capital expenditures, of which the majority were for the oil and gas segment, were approximately $1.8 billion for the three months ended March 31, 2024, compared to $1.5 billion for the three months ended March 31, 2023.
Occidental’s net cash used by financing activities was $0.3 billion for the three months ended March 31, 2024, compared to $1.1 billion for the three months ended March 31, 2023. Cash used in financing activities for the three months ended March 31, 2024 included cash dividends paid of $332 million. Cash used in financing activities for the three months ended March 31, 2023 included treasury share repurchases of $732 million and cash dividends paid of $320 million.
Occidental’s Zero Coupons can be put to Occidental in October of each year, in whole or in part, for the then accreted value of the outstanding Zero Coupons. The Zero Coupons can next be put to Occidental in October 2024, which, if put in whole, would require a payment of approximately $362 million at such date. Occidental currently has the ability to meet this obligation and may use available capacity under the RCF and other committed facilities to satisfy the put should it be exercised.
As of March 31, 2024, and through the date of this filing, Occidental was in compliance with all covenants in its financing agreements. Occidental has debt maturities of $1.1 billion in 2024, $1.2 billion in 2025, $1.4 billion in 2026, $0.9 billion in 2027 and $13.3 billion thereafter. Occidental currently expects its cash on hand, operating cash flows and funds available from the RCF and other committed facilities to be sufficient to meet its near-term debt maturities, operating expenditures, capital expenditures and other obligations, excluding the CrownRock Acquisition as discussed below, for the next 12 months from the date of this filing.
Occidental or its subsidiaries have provided financial assurances through a combination of cash, letters of credit and surety bonds. As of March 31, 2024, Occidental had not issued any letters of credit under the RCF or other committed facilities. For additional information, see Risk Factors in Part I, Item 1A of Occidental’s 2023 Form 10-K.
CROWNROCK ACQUISITION FINANCING
In connection with the planned CrownRock Acquisition, Occidental has secured a fully-committed $5.3 billion bridge loan facility, a $2.0 billion 364-day term loan, and a $2.7 billion two-year term loan. Prior to or concurrent with the closing of the acquisition, Occidental plans to issue new debt comprised of a combination of the one and two-year term loans and senior unsecured notes. In addition, Occidental plans to refinance a majority of the $1.2 billion of CrownRock’s existing debt assumed in the acquisition. Occidental intends to repay at least $4.5 billion of debt within 12 months of closing the CrownRock Acquisition with proceeds from the divestiture program and excess cash flows.
DIVESTITURE PROGRAM
In the fourth quarter of 2023, Occidental announced a divestiture program between $4.5 billion and $6.0 billion in connection with the CrownRock Acquisition, which Occidental expects to complete within 18 months of closing the CrownRock Acquisition.
SHARE REPURCHASE PROGRAM
As of March 31, 2024, Occidental has approximately $1.2 billion remaining under its share repurchase program, which was authorized in 2023.

ENVIRONMENTAL LIABILITIES AND EXPENDITURES

Occidental’s operations are subject to stringent federal, regional, state, provincial, tribal, local and international laws and regulations related to improving or maintaining environmental quality. Occidental’s environmental compliance costs have generally increased over time and are expected to rise in the future. Occidental factors environmental expenditures for its operations as an integral part of its business planning process.
The laws that require or address environmental remediation, including CERCLA and similar federal, regional, state, provincial, tribal, local and international laws, may apply retroactively and regardless of fault, the legality of the original activities or the current ownership or control of sites. Occidental or certain of its subsidiaries participate in or actively monitor a range of remedial activities and government or private proceedings under these laws with respect to alleged past practices at Third-Party, Currently Operated, and Closed or Non-Operated Sites, which categories may include NPL Sites. Remedial activities may include one or more of the following: investigation involving sampling, modeling, risk assessment or monitoring; cleanup measures including removal, treatment or disposal; or operation and maintenance of remedial systems. The environmental proceedings seek funding or performance of remediation and, in some cases, compensation for alleged property damage, natural resource damages, punitive damages, civil penalties, injunctive relief and government oversight costs.
See Note 8 - Environmental Liabilities and Expenditures in the notes to the Consolidated Condensed Financial
33

Statements in Part I, Item 1 of this Form 10-Q and the Environmental Liabilities and Expenditures section of Management’s Discussion and Analysis of Financial Condition and Results of Operations in the 2023 Form 10-K for additional information regarding Occidental’s environmental liabilities and expenditures.

LAWSUITS, CLAIMS, COMMITMENTS AND CONTINGENCIES

Occidental accrues reserves for outstanding lawsuits, claims and proceedings when it is probable that a liability has been incurred and the liability can be reasonably estimated. Occidental has disclosed its reserve balances for environmental remediation matters and its estimated range of reasonably possible additional losses for such matters. See Note 8 - Environmental Liabilities and Expenditures and Note 9 - Lawsuits, Claims, Commitments and Contingencies in the notes to the Consolidated Condensed Financial Statements in Part I, Item 1 of this Form 10-Q for further information.
Item 3. Quantitative and Qualitative Disclosures About Market Risk
For the three months ended March 31, 2024, there were no material changes in the information required to be provided under Item 305 of Regulation S-K included under Item 7A, Quantitative and Qualitative Disclosures About Market Risk in the 2023 Form 10-K.

Based upon that evaluation, Occidental's President and Chief Executive Officer and Senior Vice President and Chief Financial Officer concluded that Occidental's disclosure controls and procedures were effective as of March 31, 2024.
There has been no change in Occidental’s internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the three months ended March 31, 2024 that has materially affected, or is reasonably likely to materially affect, Occidental’s internal control over financial reporting.
Part II Other Information
Item 1. Legal Proceedings
Occidental has elected to use a $1 million threshold for disclosing certain proceedings arising under federal, state or local environmental laws when a governmental authority is a party and potential monetary sanctions are involved. For information regarding legal proceedings, see Note 9 - Lawsuits, Claims, Commitments and Contingencies in the notes to the Consolidated Condensed Financial Statements in Part I, Item 1 of this Form 10-Q.
Item 1A. Risk Factors
There have been no material changes from the risk factors included under Part I, Item 1A of Occidental’s 2023 Form 10-K for the year ended December 31, 2023.
Item 5. Other Information
During the three months ended March 31, 2024, no director or Section 16 officer of Occidental adopted or terminated any Rule 10b5-1 trading arrangements or non-Rule 10b5-1 trading arrangements (in each case, as defined in Item 408(a) of Regulation S-K).
