Notes to Consolidated Condensed Financial StatementsOccidental Petroleum Corporation and Subsidiaries
NOTE 1 - GENERAL

NATURE OF OPERATIONS
In this report, "Occidental" means Occidental Petroleum Corporation, a Delaware corporation, and one or more entities in which it owns a controlling interest (subsidiaries). 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 Occidental’s Annual Report on Form 10-K for the year ended December 31, 2020 (the 2020 Form 10-K).
In the opinion of Occidental’s management, the accompanying unaudited consolidated condensed financial statements contain all adjustments (consisting of normal recurring adjustments) necessary to fairly present Occidental’s consolidated condensed balance sheets as of June 30, 2021 and December 31, 2020, and the consolidated condensed statements of operations, comprehensive income (loss), cash flows and equity for the three and six months ended June 30, 2021 and 2020. Certain data in the financial statements and notes for prior periods have been reclassified to conform to the current presentation. The income and cash flows for the periods ended June 30, 2021 and 2020 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 at June 30, 2021 and 2020 included 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 at the end of the period in the consolidated condensed statements of cash flows for the six months ended June 30, 2021 and 2020, respectively.

Restricted cash and restricted cash equivalents included in long-term receivables and other assets, net17 78 
Cash, cash equivalents, restricted cash and restricted cash equivalents$4,766 $1,213 

Total restricted cash and restricted cash equivalents are primarily associated with international joint ventures, a benefits trust and a judicially controlled account related to a Brazilian tax dispute.

SUPPLEMENTAL CASH FLOW INFORMATION
The following table represents U.S. federal, domestic state and international income taxes paid, tax refunds received and interest paid related to continuing operations during the six months ended June 30, 2021 and 2020, respectively.

WES INVESTMENT
In March 2021, Occidental sold 11.5 million limited partner units of Western Midstream Partners, LP (WES) for proceeds of approximately $200 million, resulting in a gain of $102 million. As of June 30, 2021, Occidental owned all of the 2% non-voting general partner interest and 49.1% of the limited partner units in WES. On a combined basis, with its 2.0% non-voting limited partner interest in WES Operating, a WES subsidiary, Occidental's total effective economic interest in WES and its subsidiaries was 51.2%.
The following table presents the related-party transactions between Occidental and WES for the six months ended June 30, 2021 and 2020.

Sales$91 $119 
Purchases$17 $311

DISCONTINUED OPERATIONS
Occidental is continuing to actively market its Ghana assets. The results of operations in Ghana, after-tax income of $7 million for the three months ended June 30, 2021 and after-tax losses of $35 million for the six months ended June 30, 2021, continue to be presented as discontinued operations. The amounts related to the Ghana assets, of which approximately $1.2 billion and $1.4 billion are related to property, plant and equipment, net, as of June 30, 2021 and December 31, 2020, respectively, and the amounts related to Ghana liabilities, of which approximately $600 million and $670 million are related to deferred income taxes, asset retirement obligations and a finance lease liability as of June 30, 2021 and December 31, 2020, respectively, are presented as assets and liabilities held for sale.
During the first quarter of 2021, Occidental recorded a $403 million after-tax loss contingency in discontinued operations associated with its former operations in Ecuador, see Note 8 - Lawsuits, Claims, Commitments and Contingencies.

NOTE 2 - DIVESTITURES AND OTHER TRANSACTIONS

DIVESTITURES
In June 2021, Occidental entered into an agreement to sell certain non-strategic assets in the Permian Basin. The transaction closed on July 29, 2021 for net proceeds of approximately $475 million. The difference in the asset’s net book value and adjusted purchase price was treated as a recovery of cost and normal retirement, which resulted in no gain or loss being recognized. The disposal group’s assets and liabilities, of which approximately $525 million is related to property, plant and equipment, net and approximately $50 million is related to asset retirement obligations, were presented as held for sale as of June 30, 2021.
In March 2021, Occidental completed the sale of certain non-operated assets in the DJ Basin for net cash proceeds of approximately $280 million. The difference in the asset’s net book value and adjusted purchase price was treated as a recovery of cost and normal retirement, which resulted in no gain or loss being recognized.

NOTE 3 - REVENUE

Revenue from customers is recognized when obligations under the terms of a contract with our customers are satisfied, which generally occurs with the delivery of oil, natural gas liquids (NGL), gas, chemicals or services, such as transportation. As of June 30, 2021, trade receivables, net, of $3.3 billion represented 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 presents a reconciliation of revenue from customers to total net sales for the three and six months ended June 30, 2021 and 2020:

Occidental did 0t recognize any inventory impairments due to obsolescence for the six months ended June 30, 2021. During the three and six months ended June 30, 2020, Occidental recognized impairments of $42 million and $54 million, respectively, due to obsolete material and supplies inventory and impairments of $7 million and $76 million, respectively, due to lower-than-cost or net-realizable value adjustments primarily related to commodity inventories.

NOTE 5 - DERIVATIVES

OBJECTIVE AND STRATEGY
Occidental uses a variety of derivative financial instruments and physical contracts to manage its exposure to commodity price fluctuations, interest rate risks and transportation commitments and to fix margins on the future sale of stored commodity volumes. 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 future debt issuances. The value of cash flow hedges was insignificant at June 30, 2021 and December 31, 2020. Derivatives are carried at fair value and on a net basis when a legal right of offset exists with the same counterparty.

DERIVATIVES NOT DESIGNATED AS HEDGING INSTRUMENTS
As of June 30, 2021, Occidental’s derivatives not designated as hedging instruments consisted of oil call options, natural gas collars, interest rate swaps and marketing derivatives.
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. The fair value does not reflect the ultimate realized cash value of the instrument at settlement.

COLLARS AND OIL CALL OPTIONS
Occidental's Brent-priced call options were entered into in conjunction with three-way collars that expired in 2020. Net gains and losses associated with collars and calls are recognized in net sales.
Occidental's natural gas two-way collar derivative instruments settle in 2021 and were entered into to manage its near-term exposure to cash flow variability from natural gas price risk.
Occidental had the following collars and calls outstanding at June 30, 2021:
Collars and Calls, not designated as hedges
2021 Settlement - oil
Call options sold (MMbbl)64.4 
Average price per barrel (Brent oil pricing)

Natural gas collars (millions of MMbtu)96.4 
Volume weighted-average price per MMbtu (NYMEX)
Ceiling sold price (call)$3.61 
Floor purchased price (put)$2.50 

INTEREST RATE SWAPS
Occidental's interest rate swap contracts lock in a fixed interest rate in exchange for a floating interest rate indexed to the three-month London InterBank Offered Rate (LIBOR) throughout the reference period. Net gains and losses associated with interest rate swaps are recognized currently in gains (losses) on interest rate swaps and warrants, net.
Occidental had the following interest rate swaps outstanding at June 30, 2021:

$450 September 2017 - 2047September 20236.445 %

13


Depending on market conditions, liability management actions or other factors, Occidental may enter into offsetting interest rate swap positions as well as amend or settle certain or all of the currently outstanding interest rate swaps.
Derivative settlements and collateralization are classified as cash flow from operating activities unless the derivatives contain an other-than-insignificant financing element, in which case the settlements and collateralization are classified as cash flows from financing activities. Net cash payments related to settlements of interest rate swap agreements were $47 million for the six months ended June 30, 2021. For the six months ended June 30, 2021, $49 million of collateral was returned.

MARKETING DERIVATIVES
Occidental's marketing derivative instruments not designated as hedges are short-duration physical and financial forward contracts. Marketing derivative instruments do not include the collars and call options discussed above. A substantial majority of Occidental's physically settled derivative contracts are index-based and carry no mark-to-market valuation in earnings. As of June 30, 2021, the weighted-average settlement price of these forward contracts was $69.05 per barrel (Bbl) and $3.61 per thousand cubic feet (Mcf) for crude oil and natural gas, respectively. The weighted-average settlement price was $46.05 per Bbl and $2.58 per Mcf for crude oil and natural gas, respectively, at December 31, 2020. Net gains and losses associated with marketing derivative instruments not designated as hedging instruments are recognized currently in net sales.

CREDIT RISK
The majority of Occidental's counterparty credit risk is related to the physical delivery of energy commodities to its customers and their 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 future contracts through regulated exchanges with select clearinghouses and brokers, which are subject to minimal credit risk as a significant portion of these transactions settle on a daily margin basis.
Certain of Occidental's over-the-counter derivative instruments contain credit-risk-contingent features, primarily tied to credit ratings for Occidental or its counterparties, which may affect the amount of collateral that each party would need to post. The aggregate fair value of derivative instruments with credit-risk-contingent features for which a net liability position existed at June 30, 2021, was $110 million (net of $326 million of collateral), which was primarily related to interest rate swaps. The aggregate fair value of derivative instruments with credit-risk-contingent features for which a net liability position existed at December 31, 2020, was $104 million (net of $374 million of collateral), which was primarily related to interest rate swaps.

NOTE 6 - FAIR VALUE MEASUREMENTS

Occidental has categorized its assets and liabilities that are measured at fair value in a three-level fair value hierarchy, based on the inputs to the valuation techniques: Level 1 — using quoted prices in active markets for the assets or liabilities; Level 2 — using observable inputs other than quoted prices for the assets or liabilities; and Level 3 — using unobservable inputs. Transfers between levels, if any, are recognized at the end of each reporting period.

FAIR VALUES - RECURRING
In January 2012, Occidental entered into a long-term contract to purchase carbon dioxide (CO2). This contract contains a price adjustment clause that is linked to changes in NYMEX oil prices. Occidental determined that the portion of this contract linked to NYMEX oil prices is not clearly and closely related to the host contract, and Occidental therefore bifurcated this embedded pricing feature from its host contract and accounts for it at fair value in the consolidated financial statements.

FAIR VALUES - NONRECURRING
2021:
For the three and six months ended June 30, 2021, Occidental recorded pre-tax impairments of $21 million and $156 million, respectively, related to non-core onshore and offshore domestic undeveloped leases that either expired or were set to expire in the near-term, where Occidental had no plans to pursue exploration activities.

2020:
As a result of the expected prolonged period of lower commodity prices brought on by the COVID-19 pandemic’s impact on oil demand, Occidental tested substantially all of its oil and gas assets for impairment during the second quarter of 2020. Occidental recognized total pre-tax impairments to its oil and gas proved and unproved properties of $8.6 billion, of which $6.4 billion was included in oil and gas segment results and $2.2 billion ($1.4 billion net of tax) related to Ghana was included in discontinued operations for the three months ended June 30, 2020.
For the three months ended June 30, 2020, Occidental recorded proved property pre-tax impairments of $1.2 billion primarily related to certain assets for its domestic onshore and Gulf of Mexico assets and $0.9 billion to remeasure the Algeria oil and gas proved properties to their fair value. The fair value of the proved properties was measured based on the income approach.
Also during the three months ended June 30, 2020, $4.3 billion of unproved property pre-tax impairments were recorded primarily related to domestic onshore unproved acreage. The fair value of this acreage was measured based on a market approach using an implied acreage valuation derived from domestic onshore market participants excluding the fair value assigned to proved properties.
Income approaches are considered Level 3 fair value estimates and include significant assumptions of future production and timing of production, commodity price assumptions, and operating and capital cost estimates, discounted using a 10% weighted average cost of capital. Taxes were based on current statutory rates. Future production and timing of production is based on internal reserves estimates and internal economic models for a specific oil and gas asset. Internal reserve estimates consisted of proved reserves and risk adjusted unproved reserves based on reserve category. Price assumptions were based on a combination of market information and published industry resources adjusted for historical differentials. Price assumptions ranged from approximately $40 per Bbl of oil in 2020 increasing to approximately $70 per Bbl of oil in 2034, with an unweighted arithmetic average price of $59.17 and $62.42 for WTI and Brent indexed assets for the 15-year period, respectively. Natural gas prices ranged from approximately $2.00 per Mcf in 2020 to approximately $3.60 per Mcf in 2034, with an unweighted arithmetic average price of $3.13 for NYMEX based assets for the 15-year period. Both oil and natural gas commodity prices were held flat after 2034 and were adjusted for location and quality differentials. Operating and capital cost estimates were based on current observable costs and were further escalated 1% in every period where commodity prices exceeded $50 per Bbl and 2% in every period where commodity prices exceeded $60 per Bbl. The weighted average cost of capital is calculated based on industry peers and approximates the cost of capital an external market participant would expect to obtain.
In the first quarter of 2020, Occidental's oil and gas segment recognized pre-tax impairment and related charges of $581 million primarily related to both proved and unproved oil and gas properties and a lower of cost or net realizable value adjustment for crude inventory. Occidental recorded proved property impairments of $293 million related to certain international assets and the Gulf of Mexico. Occidental recorded unproved property impairments of $241 million primarily related to domestic onshore undeveloped leases and offshore Gulf of Mexico where Occidental no longer intends to pursue exploration, appraisal or development activities primarily due to the reduction in near-term capital plans.

NOTE 8 - 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 the Comprehensive Environmental Response, Compensation, and Liability Act (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, punitive damages, civil penalties and injunctive relief. Usually Occidental or such subsidiaries are among many companies in these environmental proceedings and have to date been successful in sharing response 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 retains liability or indemnifies the other party for conditions that existed prior to the transaction.
In accordance with applicable accounting guidance, 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.
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 60% of the value of Block 15. In 2017, Andes Petroleum Ecuador Ltd. (Andes) filed a demand for arbitration, claiming it is entitled to a 40% share of the judgment amount obtained by Occidental. Occidental contends 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. On March 26, 2021, the arbitration tribunal issued an award in favor of Andes and against Occidental Exploration and Production Company (OEPC) in the amount of approximately $391 million plus interest. In June 2021, OEPC filed a motion to vacate the award due to concerns regarding the validity of the award. In addition, OEPC has made a demand for significant additional claims not addressed by the arbitration tribunal that OEPC has against Andes 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 August 2019, Sanchez Energy Corporation and certain of its affiliates (Sanchez) filed voluntary petitions for reorganization under Chapter 11 of the United States Bankruptcy Code. Sanchez is a party to agreements with Anadarko Petroleum Corporation (Anadarko) as a result of its 2017 purchase of Anadarko's Eagle Ford Shale assets. Sanchez is attempting to reject some of the agreements related to the purchase of Anadarko’s Eagle Ford Shale assets. If Sanchez is permitted to reject certain of those agreements, then Anadarko may owe deficiency payments to various third parties. Occidental expects a final ruling from the bankruptcy court on Sanchez's purported contract rejection by the end of the third quarter in 2021. Occidental intends to defend vigorously any attempt by Sanchez to reject the agreements.
On May 26, 2020, a putative securities class action captioned City of Sterling Heights General Employees’ Retirement System, et al. v. Occidental Petroleum Corporation, et al., No. 651994/2020 (City of Sterling), was filed in the Supreme Court of the State of New York. The complaint asserted claims under Sections 11, 12 and 15 of the Securities Act of 1933, as amended (the Securities Act), based on alleged misstatements in the Securities Act filings, including the registration statement filed in connection with the acquisition of Anadarko and Occidental’s related issuance of common stock and debt securities offerings that took place in August 2019. The lawsuit was filed against Occidental, certain current and former officers and directors and certain underwriters of the debt securities offerings and sought damages in an unspecified amount, plus attorneys’ fees and expenses. Two additional putative class actions were filed in the same court (together with City of Sterling, the State Cases) and the State Cases were consolidated into In re Occidental Petroleum Corporation Securities Litigation, No. 651830/2020. On March 4, 2021, the court dismissed the complaint, and on July 1, 2021, the court entered judgment.
The ultimate outcome and impact of outstanding lawsuits, claims and proceedings on Occidental cannot be predicted. Management believes that the resolution of these matters will not, individually or in the aggregate, have a material adverse effect on 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 reassesses the probability and estimability of contingent losses as new information becomes available.

19


TAX MATTERS
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. Taxable years through 2017 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. Taxable years through 2009 have been audited for state income tax purposes. All other significant audit matters in international jurisdictions have been resolved through 2010. During the course of tax audits, disputes have arisen and other disputes may arise as to facts and matters of law. Occidental believes that the resolution of outstanding tax matters would not have a material adverse effect on its consolidated condensed balance sheets or consolidated condensed statements of operations.
For Anadarko, its taxable years through 2014 and tax year 2016 for U.S. federal and state income tax purposes have been audited by the IRS and respective state taxing authorities. There are outstanding significant audit matters in one international jurisdiction. 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 matter discussed below, Occidental believes that the resolution of these outstanding tax matters would not have a material adverse effect on its consolidated condensed balance sheets or consolidated condensed statements 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. The case was in the IRS appeals process until the second quarter of 2020. The case has since been returned to the U.S. Tax Court, where a trial date has been set for July 2022 and Occidental expects to continue pursuing resolution.
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. 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, Occidental would be required to repay approximately $935 million ($908 million in federal taxes and $27 million in state taxes) plus accrued interest of approximately $284 million. A liability for this amount plus 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. These indemnities usually are contingent upon the other party incurring liabilities that reach specified thresholds. As of June 30, 2021, 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.

NOTE 9 - 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. 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 operating, closed and third-party 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, punitive damages, civil penalties, injunctive relief and government oversight costs.

ENVIRONMENTAL REMEDIATION
As of June 30, 2021, Occidental participated in or monitored remedial activities or proceedings at 166 sites. The following table presents Occidental’s current and non-current environmental remediation liabilities as of June 30, 2021. The current portion, $123 million, is included in accrued liabilities and the non-current portion, $1.0 billion, in deferred credits and other liabilities - environmental remediation liabilities.
20


Occidental’s environmental remediation sites are grouped into four categories: sites listed or proposed for listing by the U.S. Environmental Protection Agency (EPA) on the CERCLA National Priorities List (NPL) and three categories of non-NPL sites—third-party sites, Occidental-operated sites and closed or non-operated Occidental sites.
millions, except number of sitesNumber of SitesRemediation Balance
NPL sites32 $438 
Third-party sites68 299 
Occidental-operated sites17 136 
Closed or non-operated Occidental sites49 270 
Total166 $1,143 

As of June 30, 2021, Occidental’s environmental remediation liabilities exceeded $10 million each at 19 of the 166 sites described above, and 94 of the sites had liabilities from 0 to $1 million each. Based on current estimates, Occidental expects to expend funds corresponding to approximately 50% of the period-end remediation balance at the sites described above over the next three to four years and the remaining balance at these sites over the subsequent 10 or more years. Occidental believes its range of reasonably possible additional losses beyond those liabilities recorded for environmental remediation at these sites could be up to $1.1 billion. The status of Occidental's involvement with the sites and related significant assumptions, including those sites indemnified by Maxus Energy Corporation (Maxus), has not changed materially since December 31, 2020.

MAXUS ENVIRONMENTAL SITES
When Occidental acquired Diamond Shamrock Chemicals Company in 1986, Maxus, a subsidiary of YPF S.A., agreed to indemnify Occidental for a number of environmental sites, including the Diamond Alkali Superfund Site (Site) along a portion of the Passaic River. On June 17, 2016, Maxus and several affiliated companies filed for Chapter 11 bankruptcy in federal district court in the State of Delaware. Prior to filing for bankruptcy, Maxus defended and indemnified Occidental in connection with clean-up and other costs associated with the sites subject to the indemnity, including the Site.
In March 2016, the EPA issued a Record of Decision (ROD) specifying remedial actions required for the lower 8.3 miles of the Lower Passaic River. The ROD does not address any potential remedial action for the upper 9 miles of the Lower Passaic River or Newark Bay. During the third quarter of 2016, and following Maxus’ bankruptcy filing, Occidental and the EPA entered into an Administrative Order on Consent (AOC) to complete the design of the proposed clean-up plan outlined in the ROD at an estimated cost of $165 million. The EPA announced that it will pursue similar agreements with other potentially responsible parties.
Occidental has accrued a reserve relating to its estimated allocable share of the costs to perform the design and remediation called for in the AOC and the ROD as well as for certain other Maxus-indemnified sites. Occidental's accrued estimated environmental reserve does not consider any recoveries for indemnified costs. Occidental’s ultimate share of this liability may be higher or lower than the reserved amount, and is subject to final design plans and the resolution of Occidental's allocable share with other potentially responsible parties. Occidental continues to evaluate the costs to be incurred to comply with the AOC and the ROD and to perform remediation at other Maxus-indemnified sites in light of the Maxus bankruptcy and the share of ultimate liability of other potentially responsible parties. In June 2018, Occidental filed a complaint under CERCLA in federal district court in the State of New Jersey against numerous potentially responsible parties for reimbursement of amounts incurred or to be incurred to comply with the AOC and the ROD, or to perform other remediation activities at the Site.
In June 2017, the court overseeing the Maxus bankruptcy approved a Plan of Liquidation (Plan) to liquidate Maxus and create a trust to pursue claims against current and former parents YPF and each of its respective subsidiaries and affiliates (YPF) and Repsol, S.A. and each of its respective subsidiaries and affiliates (Repsol), as well as others to satisfy claims by Occidental and other creditors for past and future cleanup and other costs. In July 2017, the court-approved Plan became final and the trust became effective. The trust is pursuing claims against YPF, Repsol and others and is expected to distribute assets to Maxus' creditors in accordance with the trust agreement and Plan. In June 2018, the trust filed its complaint against YPF and Repsol in Delaware bankruptcy court asserting claims based upon, among other things, fraudulent transfer and alter ego. During 2019, the bankruptcy court denied Repsol's and YPF's motions to dismiss the complaint as well as their motions to move the case away from the bankruptcy court. Discovery remains ongoing at the time of this report.

Occidental has various defined contribution and defined benefit plans for its salaried, domestic union and non-union hourly and certain foreign national employees. In addition, Occidental also provides medical and other benefits for certain active, retired and disabled employees and their eligible dependents.
The following table contains a summary of Occidental's retirement and postretirement benefits plan costs for the three and six months ended June 30, 2021 and 2020:

25


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 and the prices it receives for its chemical products. Oil prices have increased significantly in 2021. Occidental's average worldwide realized price for the three months ended June 30, 2021 was $64.18, compared to $23.14 in the same period of 2020. While the worldwide economy continues to be impacted by the ongoing effects of the COVID-19 pandemic and emergence and spread of new variants of the virus, demand for Occidental's products has increased with the lifting of certain restrictions, including certain travel restrictions and stay-at-home orders. Subsequent to June 30, 2021, members of OPEC and 10 non-OPEC partner countries (OPEC+) agreed to a phased increase in production over the next eighteen months in anticipation of a return to pre-pandemic oil demand. Current oil prices could be negatively impacted by a resurgence of COVID-19 cases, slow vaccine distribution in certain large international economies, or the recurrence or tightening of travel restrictions and stay-at-home orders. We expect that oil prices in the near-term will continue to be influenced by the duration and severity of the COVID-19 pandemic and its resulting impact on oil and gas demand.
Occidental's operational priorities for 2021 continue to be to maximize cash flow by sustaining production in-line with its 2020 fourth quarter rate with an annualized $2.9 billion capital budget and by maintaining a majority of the cost savings achieved in 2020. Occidental intends to use excess cash flow generated during 2021, coupled with divestiture proceeds, to continue to strengthen its balance sheet by reducing its debt and other financial obligations.

LIABILITY MANAGEMENT
In July 2021, Occidental settled cash tender offers to purchase approximately $3.1 billion in outstanding senior notes, inclusive of accrued interest and premiums, with maturities ranging from 2022 through 2026. Subsequent to the purchase and retirement of these senior notes, Occidental's face value of debt was approximately $32.0 billion. In addition, during the first quarter of 2021, Occidental repaid $174 million of debt upon maturity. Subsequent to the completion of the July tender offers, Occidental has remaining near-term debt maturities of approximately $224 million in 2021, $1.8 billion in 2022 and $465 million in 2023.
In addition to the above, Occidental’s Zero Coupon senior notes due 2036 (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 2021, which, if put in whole, would require a payment of approximately $1.0 billion at such date. Occidental currently has the ability to meet this obligation and may use available capacity under the revolving credit facility (RCF) to satisfy the put should it be exercised.
Interest rate swaps with a notional value of $750 million and a fair value of approximately $800 million, as of June 30, 2021, have a mandatory termination date in September 2021. Occidental intends to cash settle these in the third quarter of 2021. Interest rate swaps with a notional value of $725 million and a fair value of $405 million, net of collateral, as of June 30, 2021, have mandatory termination dates in September 2022 and 2023, respectively. The interest rate swaps' fair value, and cash required to settle on their termination dates, will continue to fluctuate with changes in interest rates through the mandatory termination dates. Depending on market conditions, liability management actions or other factors, Occidental may enter into offsetting interest rate swap positions or amend or settle certain or all of the currently outstanding interest rate swaps, as appropriate.
As of the date of this filing, Occidental had $5.0 billion of committed borrowing capacity under its RCF, which matures in January 2023. Additionally, Occidental has up to $400 million of capacity, subject to monthly redetermination, under its receivables securitization facility, which matures in November 2022. Occidental continues to pursue divestitures of certain assets and intends to use excess cash flow and the net proceeds from asset sales to repay debt maturities and other financial obligations, however the expected timing and final proceeds from such asset sales are uncertain. Occidental expects its cash on hand and funds available under its RCF to be sufficient to meet its near-term debt maturities, operating expenditures and other obligations for the next 12 months from the date of this filing.

DEBT RATINGS
As of June 30, 2021, Occidental’s long-term debt was rated Ba2 by Moody’s Investors Service, BB by Fitch Ratings and BB- by Standard and Poor’s. Any downgrade in credit ratings could impact Occidental's ability to access capital and increase its cost of capital. In addition, given that Occidental’s current debt ratings are non-investment grade, Occidental may be requested, and 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 its performance and payment obligations under certain contractual arrangements such as pipeline transportation contracts, environmental remediation obligations, oil and gas purchase contracts and certain derivative instruments.
As of the date of this filing, Occidental has provided required financial assurances through a combination of cash, letters of credit and surety bonds made available to it on a bilateral basis and has 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 2020 Form 10-K.
26



IMPACT OF COVID-19 PANDEMIC TO GLOBAL OPERATIONS
Occidental continues to focus on protecting the health and safety of its employees and contractors during the COVID-19 pandemic. Certain workplace restrictions implemented in the initial stages of the pandemic for our offices and work sites for health and safety reasons were lifted in the second quarter of 2021 due to higher vaccination rates and lower infection rates. Other restrictions remain in place. Occidental has not incurred material costs as a result of new protocols and procedures. Occidental continues to monitor national, state and local government directives where it has operations and/or offices. While Occidental has not incurred any significant disruptions to its day-to-day operations as a result of any workplace restrictions related to the COVID-19 pandemic to date, the situation is still rapidly changing with the emergence and spread of new variants and the extent to which the COVID-19 pandemic adversely affects the business, results of operations and financial condition will depend on future developments, which remain uncertain.

CONSOLIDATED RESULTS OF OPERATIONS

Occidental reported after-tax income from continuing operations of $100 million on net sales of $6.0 billion, for the three months ended June 30, 2021, compared to an after tax loss from continuing operations of $6.7 billion on net sales of $2.9 billion for the same period of 2020. Diluted loss from continuing operations per share was $0.11 for the three months ended June 30, 2021 compared to $7.58 for the same period of 2020.
Occidental reported after-tax income from continuing operations of $399 million on net sales of $11.3 billion for the six months ended June 30, 2021, compared to an after-tax loss from continuing operations of $8.7 billion on net sales of $9.5 billion for the same period of 2020. Diluted loss from continuing operations per share was zero for the six months ended June 30, 2021 compared to $10.12 for the same period of 2020.
Excluding the impact of asset impairments, gains and losses on sales of assets and equity investments, gains and losses on derivative mark-to-market adjustments and acquisition-related costs, the increase in income from continuing operations for the three and six months ended June 30, 2021, compared to the same periods in 2020, was primarily related to higher crude oil, NGL and natural gas prices, higher marketing margins and increases in prices across most chemical product lines, partially offset by lower crude oil sales volumes, higher depreciation, depletion and amortization (DD&A) rates and higher chemical ethylene and energy costs.

SELECTED STATEMENTS OF OPERATIONS ITEMS
Net sales increased for the three and six months ended June 30, 2021, compared to the same periods in 2020, primarily as a result of higher crude oil, NGL and natural gas prices, increases in prices across most chemical product lines and higher marketing margins, partially offset by lower crude oil sales volumes.
Oil and gas operating expenses decreased for the six months ended June 30, 2021, compared to the same period in 2020, as a result of lower oil and gas production volumes. Transportation and gathering expenses decreased for the six months ended June 30, 2021, compared to the same period in 2020, primarily as a result of lower domestic oil and gas production volumes. The cost of purchased commodities increased for the three and six months ended June 30, 2021, compared to the same periods in 2020, due to higher crude prices on third-party crude purchases related to the midstream and marketing segment.
DD&A expense increased for the three and six months ended June 30, 2021 compared to the same periods in 2020, as a result of higher DD&A rates due to lower reported proved reserves volumes, consistent with lower average prices in 2020. Occidental undertook a mid-year reserve review, which will result in lower DD&A rates for the second half of 2021 due to increased proved reserves primarily related to positive price revisions. Proved oil, NGL and natural gas reserves were estimated during this mid-year review using the unweighted arithmetic average of the first-day-of-the-month price for each month for the twelve months ended June 30, 2021, unless prices were defined by contractual arrangements.
Asset impairments and other charges for the three months ended June 30, 2020 included $6.4 billion in pre-tax impairments on oil and gas proved and unproved properties. In addition, asset impairments and other charges for the six months ended June 30, 2020 included a $1.2 billion impairment of goodwill attributable to Occidental's ownership in WES as well as $546 million of other impairments on proved and unproved oil and gas properties.
Gains (losses) on interest rate swaps and warrants, net, increased for the six months ended June 30, 2021, compared to the same period in 2020, primarily due to rising interest rates in the first quarter of 2021, resulting in a favorable change in the fair value of interest rate swaps.
Income from equity investments for the six months ended June 30, 2020 included a loss of approximately $240 million from WES' write-off of its goodwill.
Income tax expense increased for the three and six months ended June 30, 2021, compared to the same periods in 2020, primarily due to higher crude oil, NGL and natural gas prices. See further discussion under the heading Income Taxes below.

SEGMENT RESULTS OF OPERATIONS AND ITEMS AFFECTING COMPARABILITY
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, condensate, NGL, natural gas, CO2 and power. It also trades around its assets, including transportation and storage capacity, and invests in entities that conduct similar activities such as WES.
The following table sets forth the sales and earnings of each operating segment and corporate items for the three and six months ended June 30, 2021 and 2020:

OIL AND GAS SEGMENT
Oil and gas segment income was $631 million and $569 million for the three and six months ended June 30, 2021, respectively, compared with segment losses of $7.7 billion and $7.5 billion for the same periods in 2020, respectively. Excluding the impact of asset impairments and other charges and oil, gas and CO2 derivative gains (losses), oil and gas segment results for the three and six months ended June 30, 2021, compared to the same periods in 2020, reflected higher commodity prices, partially offset by lower sales volumes and higher DD&A rates.
The following table sets forth the average sales volumes per day for oil in thousands of barrels (Mbbl), for NGL in thousands of barrels equivalent (Mboe) and for natural gas in millions of cubic feet (MMcf):

The decrease in average daily sales volumes from continuing operations of 187 Mboe/d for the three months ended June 30, 2021, compared to the same period in 2020, primarily reflected declines in the Permian and DJ Basins as a result of reduced capital investment.
Total average daily sales volumes from continuing operations for the first six months of 2021 and 2020 were 1,156 Mboe/d and 1,409 Mboe/d, respectively. The decrease in average daily sales volumes from continuing operations of 253 Mboe/d for the six months ended June 30, 2021, compared to the same period in 2020, primarily reflected declines in the Permian and DJ Basins as a result of reduced capital investment.

(a) For the three months ended June 30, 2020, average realized prices decreased relative to indexed prices due to price volatilities as a result of the COVID-19 pandemic, which decreased demand resulting in significant declines in regional oil prices especially in the Permian and DJ Basins.

CHEMICAL SEGMENT
Chemical segment earnings for the three and six months ended June 30, 2021 were $312 million and $563 million, respectively, compared to $108 million and $294 million for the same periods in 2020, respectively. Compared to the same periods in 2020, the three and six months ended June 30, 2021 reflected improved prices across most products, partially offset by higher ethylene and energy costs.

MIDSTREAM AND MARKETING SEGMENT
Midstream and marketing segment results for the three and six months ended June 30, 2021 were a loss of $30 million and income of $252 million, respectively, compared to losses of $7 million and $1.3 billion for the same periods in 2020, respectively. Excluding the impact of impairment charges, net derivative mark-to-market gains and losses and asset sale gains and losses, the increase in midstream and marketing segment results for the three and six months ended June 30, 2021, compared to the same period in 2020, reflected optimization of natural gas transportation and higher sulfur prices at Al Hosn Gas. The results for the six months ended June 30 2021 also included higher gas margins from the marketing business' ability to optimize long-haul gas transportation during the first three months of 2021.

INCOME TAXES

The following table sets forth the calculation of the worldwide effective tax rate for income from continuing operations:
Three months ended June 30,Six months ended June 30,
millions, except percentages2021202020212020
Income (loss) from continuing operations before income taxes$143 $(8,184)$458 $(10,222)

Income (loss) from continuing operations$100 $(6,716)$399 $(8,729)
Worldwide effective tax rate30%18%13%15%

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 difference between the 30% and 13% effective tax rates for income from continuing operations for the three and six months ended June 30, 2021, and the 21% U.S. federal statutory tax rate is primarily driven by the 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%. In addition, the effective tax rate was impacted by a state margin tax rate reduction and one-time benefits associated with the settlement of federal and state audit matters.

LIQUIDITY AND CAPITAL RESOURCES

At June 30, 2021, Occidental had $4.6 billion in cash and cash equivalents and $180 million in restricted cash and restricted cash equivalents classified as current assets.
Operating cash flow from continuing operations was $4.1 billion for the six months ended June 30, 2021, compared to $1.7 billion for the same period in 2020. The increase in operating cash flow from continuing operations was primarily due to higher commodity prices during the first half of 2021 as compared to the same period in 2020. This increase was partially offset by an increase in working capital related to receivables, which increased largely as a result of the improvement in prices.
Occidental’s net cash used by investing activities from continuing operations was $1.0 billion for the six months ended June 30, 2021, compared to $2.1 billion for the same period in 2020. Capital expenditures for the six months ended June 30, 2021 and 2020 were approximately $1.3 billion and $1.7 billion, respectively, of which substantially all were for the oil and gas segment. For the six months ended June 30, 2021, proceeds from sales of equity investments and other assets, net primarily included the divestiture of non-operated assets in the DJ Basin as well as the sale of WES units.
Occidental’s net cash used by financing activities from continuing operations was $0.6 billion for the six months ended June 30, 2021, compared to approximately $2.0 billion for the same period in 2020. Cash used by financing activities for the six months ended June 30, 2021 reflected the dividend payments of $420 million on preferred and common stock and payments on current maturities of long-term debt of $174 million.
As of June 30, 2021, and as of the date of this filing, Occidental was in compliance with all covenants in its financing agreements. Occidental currently expects its cash on hand and funds available under its RCF to be sufficient to meet its near-term debt maturities, operating expenditures and other obligations for the next 12 months from the date of this filing.
For information regarding upcoming debt maturities and other near-term obligations, see the Current Business Outlook section of the Management’s Discussion and Analysis of Financial Condition and Results of Operations.

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 operating, closed and third-party 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, punitive damages, civil penalties, injunctive relief and government oversight costs.
See Note 9 - Environmental Liabilities and Expenditures in the notes to the consolidated condensed financial 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 2020 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 - 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

Except as discussed below, for the six months ended June 30, 2021, 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 2020 Form 10-K.
As of June 30, 2021, Occidental had Brent-priced call options which enhanced the upside of three-way collars that expired in 2020, with an underlying volume of 350 thousand Bbl/d. These call options settle or expire ratably throughout the remainder of 2021. Brent prices have increased substantially since December 31, 2020 and have increased the fair value of the liability of these call options. See Note 5 - Derivatives in the notes to the consolidated condensed financial statements in Part I, Item 1 of this Form 10-Q.
The following table shows a sensitivity analysis based on both a 5% and 10% change in Brent crude oil prices and their effects on the net derivative liability position of $219 million at June 30, 2021:
millions except percentages
Percent change in commodity pricesNet derivative liabilityChange to fair value from

+ 5%$(352)$(133)
- 5%$(126)$93 
+ 10%$(518)$(299)
- 10%$(67)$152 

To the extent that calendar month average Brent prices settle higher than the strike price of each settling call option, Occidental will be required to pay the differential between the prevailing Brent price and the call's strike price.

Item 4. Controls and Procedures

Occidental's President and Chief Executive Officer and its Senior Vice President and Chief Financial Officer supervised and participated in Occidental's evaluation of the effectiveness of its disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934) as of the end of the period covered by this report. Based upon that evaluation, Occidental's President and Chief Executive Officer and its Senior Vice President and Chief Financial Officer concluded that Occidental's disclosure controls and procedures were effective as of June 30, 2021.
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 Securities Exchange Act of 1934) during the three months ended June 30, 2021, that has materially affected, or is reasonably likely to materially affect, Occidental's internal control over financial reporting.
