OCCIDENTAL PETROLEUM CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS
MARCH 31,JUNE 30, 2018

1. General

In these unaudited, consolidated, condensed financial statements, "Occidental" means Occidental Petroleum Corporation, a Delaware corporation (OPC), or OPC and one or more entities in which it owns a controlling interest (subsidiaries). Occidental has made its disclosures in accordance with United States generally accepted accounting principles (GAAP) as they apply to interim reporting, and condensed or omitted, as permitted by the Securities and Exchange Commission’s rules and regulations, certain information and disclosures normally included in consolidated financial statements and the notes. 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, 2017.

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 financial position as of March 31,June 30, 2018, and the consolidated statements of operations, comprehensive income and cash flows for the three and six months ended March 31,June 30, 2018,, and 2017,, as applicable. 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 March 31,June 30, 2018, and 2017, are not necessarily indicative of the income or cash flows to be expected for the full year.

2. Asset Acquisitions, Dispositions and Other

On August 8, 2018, Occidental announced the sale of non-core domestic midstream assets. These assets to be sold include the Centurion common carrier oil pipeline and storage system, Southeast New Mexico oil gathering system, and Ingleside Crude Terminal. Following the transaction, Occidental will retain its long-term flow assurance, pipeline takeaway and export capacity through its retained marketing business. A substantial portion of the assets to be sold were classified as assets held for sale on the balance sheet at June 30, 2018. The assets held for sale were comprised primarily of midstream property, plant and equipment.

As of June 30, 2018, the remaining $250 million of assets classified as held for sale primarily relates to non-core proved and unproved Permian acreage.

In July 2018, Occidental acquired the previously leased power and steam cogeneration facility in Louisiana for $443 million, which will be paid in three installments in 2018.

In March 2018, Occidental divested non-core midstream assets for approximately $150 million, resulting in a pre-tax gain of approximately $40$43 million. In addition, Occidental classified approximately $100 million of non-core proved Permian acreage as assets held for sale at March 31, 2018.

In March 2018, Occidental issued $1.0 billion of 4.2-percent senior notes due 2048. Occidental received net proceeds of approximately $985 million. Interest on the notes will be payable semi-annually in arrears in March and September of each year, beginning on September 15, 2018. The proceeds were used to refinance the repayment of the $500 million aggregate principal amount of Occidental's 1.50-percent1.5-percent senior notes due in February 2018, with the remainder to be used for general corporate purposes.

In January 2018, Occidental entered into a new five-year, $3.0 billion revolving credit facility (2018 Credit Facility), which replacedreplacing the previous credit facility that was scheduled to expire in August 2019. The 2018 Credit Facility has similar terms to the previous credit facility and does not contain material adverse change clauses or debt ratings triggers that could restrict Occidental's ability to borrow under the facility.

3. Accounting and Disclosure Changes

In February 2018, the Financial Accounting Standards Board (FASB) released standards that allow the reclassification from accumulated other comprehensive income to retained earnings of stranded tax effects resulting from changes to U.S. federal tax law from the 2017 Tax Cuts and Jobs Act enacted in December 2017. Occidental early adopted


this standard in the first quarter of 2018, resulting in the reclassification of $58 million in stranded tax effects from accumulated other comprehensive income to retained earnings.

In the first quarter of 2018, Occidental adopted the new revenue recognition standard Topic 606 - Revenue from Contracts with Customers and related updates (ASC 606). The new standard requires more detailed disclosures related to the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. Occidental adopted the standard using the modified retrospective method. The cumulative-effect adjustment to retained earnings upon adoption was not material. See Note 4 Revenue Recognition.

In March 2017, FASB issued guidance related to presentation of net periodic pension cost and net periodic postretirement benefit cost. The rules became effective in the first quarter of 2018. These rules did not have a material impact to Occidental's financial statements upon adoption.



In January 2017, the FASB issued new guidance clarifying the definition of a business under the topic Business Combinations. The rules became effective in the first quarter of 2018, and did not have a material changeimpact to Occidental's financial statements upon adoption.

In November 2016, FASB issued new guidance related to the cash flow classification and presentation of the changes in restricted cash on the statement of cash flows. The rules became effective in the first quarter of 2018 and must be applied retrospectively. Occidental did not have restricted cash as of March 31,June 30, 2018, or December 31, 2017.

In August 2016, the FASB issued new guidance related to the classification of certain cash receipts and payments on the statement of cash flows. The rules were adopted for the first quarter of 2018 and resulted in the retrospective reclassification of $147$151 million of cash receipts from operating cash flows to investing cash flows for the threesix months ended March 31,June 30, 2017, within the Statement of Cash Flows.

In February 2016, the FASB issued rules which require Occidental to recognize most leases, including operating leases, on the balance sheet. The new rules require lessees to recognize a right-of-use asset and lease liability for all leases with lease terms of more than 12 months. The lease liability represents the discounted obligation to make future minimum lease payments. The corresponding right-of-use asset includes the discounted obligation in addition to any upfront payment or cost incurred during contract execution of the lease. The guidance retains the current accounting for lessors and does not make significant changes to the recognition, measurement and presentation of expenses and cash flows by a lessee. Recognition, measurement and presentation of expenses and cash flows arising from a lease will depend on classification as a finance or operating lease. Occidental is the lessee under various agreements for real estate, equipment, plants and facilities, aircraft and information technology hardware and vehicles that are currently accounted for as operating leases. As a result, these new rules will increase reported assets and liabilities. Occidental will not be an early adopter of this standard. Occidental will apply the revised lease rules for its interim and annual reporting periods starting January 1, 2019, using a modified retrospective approach, including several optional practical expedients related to leases that commenced before the effective date. Occidental is currently evaluating the effect of these rules on its financial statements, training accounting staff,employees, working with third-party consultants and developinghas developed an internal interim software solution for the identification, documentation, tracking, and trackingaccounting of leases in order to create an adoption plan based on Occidental's population of leases under the revised definition of leases. Occidental is currently in the test phase and continues to evaluate existing and new lease contracts for compliance. The quantitative impacts of the new standard are dependent on the leases in force at the time of adoption. As a result, the evaluation of the effect of the new standard will extend over future periods.

4. Revenue Recognition

On January 1, 2018, Occidental adopted ASC 606 using the modified retrospective method. Results for reporting periods beginning after January 1, 2018, are presented under ASC 606, while prior period amounts have not been adjusted. There was no impact of adopting ASC 606 to the opening balance of retained earnings. There was no impact to the timing or amount of revenue recognized in the first quarter ofsix months ended June 30, 2018, as a result of the adoption of ASC 606.

Revenue from customers is recognized when obligations under the terms of a contract with our customer are satisfied; whichthis generally occurs with the delivery of oil, gas, natural gas liquids ("NGL"), chemicals or services such as transportation. Revenue from customers is measured as the amount of consideration Occidental expects to receive in exchange for the delivery of goods or services. Contracts may last from one month to one year or more, and may


have renewal terms that may extend indefinitely at the option of either party. Price is typically based on market indexes. Volumes fluctuate due to production and, in certain cases, customer demand and transportation availability. Occidental records revenue net of anycertain taxes, such as sales taxes, that are assessed by governmental authorities on Occidental's customers. Occidental has elected a practical expedient under ASC 606 and will not disclose revenue recognizable in future periods for unsatisfied performance obligations because the consideration related to those performance obligations is based on volume or market prices, which are variable.

Occidental does not incur significant costs to obtain contracts. Incidental items that are immaterial in the context of the contract are recognized as expense. Sales of hydrocarbons and chemicals to customers are invoiced and settled on a monthly basis. Occidental is not usually subject to obligations for warranties, returns or refunds except in the case of customer incentive payments as discussed for the chemical segment below. Occidental does not typically receive payment in advance of satisfying its obligations under the terms of its sales contracts with customers; therefore, liabilities related to such payment are immaterial to Occidental. As of March 31,June 30, 2018, accounts receivable,trade receivables, net, of


$5.2 $5.5 billion, represents 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.

Revenue is recognized from oil and gas production when it is delivered and control passes to the customer. Revenues from the production of oil and gas properties in which Occidental has an interest with other producers are recognized on the basis of Occidental’s net revenue interest.

Chemical Segment

Revenue from chemical product sales is recognized when control passes to the customer. Certain incentive programs may provide for payments or credits to be made to customers based on the volume of product purchased over a defined period. Customer incentives are estimated and recorded as a reduction to revenue ratably over the contract period. Such estimates are evaluated and revised as warranted. Revenue from exchange contracts is excluded from revenue from customers.

Midstream and Marketing Segment

Pipeline and gas processing revenue is recognized upon the completion of the transportation or processing service. Revenue from power sales is recognized upon delivery. Net marketing margin is included in net sales, but excluded from revenue from customers. Net marketing margin is recognized upon completion of contract terms that are a prerequisite to payment and upon title transfer for physical deliveries. Unless normal sales treatment has been elected, net marketing margin is classified as a derivative, reported on a net basis, recorded at fair value and changes in fair value are reflected in net sales.

The following table shows a reconciliation of revenue from customers to total net sales (in millions):

7. Environmental Liabilities and Expenditures

Occidental’s operations are subject to stringent federal, state, local and foreign laws and regulations related to improving or maintaining environmental quality. The laws that require or address environmental remediation, including the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) and similar federal, state, local and foreign laws, may apply retroactively and regardless of fault, the legality of the original activities or the current ownership or control of sites. OPC 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 of hazardous substances; or operation and maintenance of remedial systems. These 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.

As of March 31,June 30, 2018, Occidental participated in or monitored remedial activities or proceedings at 149148 sites. The following table presents Occidental’s current and non-current environmental remediation reserves as of March 31,June 30, 2018, the current portion of which iswere included in accruedcurrent liabilities ($136140 million) and the remainder in deferred credits and other liabilities - environmental remediation reserves ($729731 million). The reserves are grouped as environmental remediation sites listed or proposed for listing by the United States Environmental Protection Agency on the CERCLA National Priorities List (NPL sites) and three categories of non-NPL sites - third-party sites, Occidental-operated sites and closed or non-operated Occidental sites.

As of March 31,June 30, 2018, Occidental’s environmental reserves exceeded $10 million each at 1516 of the 149148 sites described above, and 8891 of the sites each had reserves of $1 million or less. Based on current estimates, Occidental expects to expend funds corresponding to approximately 40-percent40 percent of the environmental reserves at the sites described above over the next three to four years and the balance at these sites over the subsequent 10 or more years.


Occidental believes its estimable amount of reasonably possible additional losses beyond those liabilities recorded for environmental remediation at these sites could range 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, 2017.

Maxus Environmental Sites

When Occidental acquired Diamond Shamrock Chemicals Company (DSCC) in 1986, Maxus, a subsidiary of YPF S.A. (YPF), 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 nine miles of the Lower Passaic River or Newark Bay. During the third quarter of 2016, and following Maxus’s 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 the 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, 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, 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 YPF, Repsol and 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. Among other responsibilities, the trust will pursue claims against YPF, Repsol and others and 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.

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 CERCLA and similar federal, state, local and foreign 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 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 percent 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 percent 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 percent economic interest in the block. Occidental intends to vigorously defend against this claim in arbitration.

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 Note 7, Environmental Liabilities and Expenditures, Occidental has disclosed its reserve balances for environmental remediation matters that satisfy this criteria. Reserve balances for matters, other than environmental remediation, that satisfy this criteria as of March 31,June 30, 2018, and December 31, 2017, were not material to Occidental’s consolidated balance sheets.

In 2017, Andes Petroleum Ecuador Ltd. filed a demand for arbitration, claiming it is entitled to a 40 percent share of the settlement payments made by the Republic of Ecuador to Occidental for the 2006 expropriation of Occidental’s Participation Contract for Ecuador’s Block 15.  Occidental intends to vigorously defend against this claim in arbitration.

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 balance sheet, statementssheet. If unfavorable outcomes of these matters were to occur, future results of operations or cash flows after consideration of recorded accruals.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.

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 foreign tax jurisdictions. Although taxable years through 2012 for United States federal income tax purposes have been audited by the United States Internal Revenue Service (IRS) pursuant to its Compliance Assurance Program, subsequent taxable years are currently under review.  Taxable years from 2002 through the current year remain subject to examination by foreign and state government tax authorities in certain jurisdictions. In certain of these jurisdictions, tax authorities are in various stages of auditing Occidental’s income taxes. 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 financial position or results of operations.

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 March 31,June 30, 2018, 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.

10. 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.



The following tables provide fair value measurement information for such assets and liabilities that are measured on a recurring basis as of March 31,June 30, 2018, and December 31, 2017 (in millions):

Fair Values — Nonrecurring

During the threesix months ended March 31,June 30, 2018, Occidental recognized pre-tax impairment charges of $30$42 million related to held for sale non-core proved and unproved Permian acreage and an investment in gas processing facilities. During the year ended December 31, 2017, Occidental recognized pre-tax impairment charges of $397 million primarily related to held for saleheld-for-sale, non-core, proved and unproved Permian acreage.

Other Financial Instruments

The carrying amounts of cash and cash equivalents and other on-balance-sheet financial instruments, other than long-term, fixed-rate debt, approximate fair value. The cost, if any, to terminate Occidental's off-balance-sheet financial instruments is not significant. Occidental estimates the fair value of fixed-rate debt based on the quoted market prices for those instruments or on quoted market yields for similarly rated debt instruments, taking into account


such instruments’ maturities. The estimated fair value of Occidental’s debt as of March 31,June 30, 2018, and December 31, 2017, was $10.6 billion and $10.4 billion respectively.for both periods. The remaining principal payments, less the discount on long-term debt, aggregated approximately $10.4 billion and $9.9 billion as of March 31,June 30, 2018, and December 31, 2017, respectively.

11. Derivatives

Occidental uses a variety of derivative financial instruments and physical contracts, including those designated as cash flow hedges, to manage its exposure to commodity price fluctuations, transportation commitments and to fix margins on the future sale of stored volumes of oil and natural gas. Where Occidental buys product for its own consumption or sells its production to a defined customer, Occidental elects normal purchases and normal sales exclusions. Occidental usually applies cash flow hedge accounting treatment to derivative financial instruments to lock in margins on the forecast sales of its natural gas storage volumes, and at times for other strategies to lock in margins. Occidental also enters into derivative financial instruments for speculative or trading purposes; however, the results of any transactions are immaterial to the marketing portfolio.

The financial instruments not designated as hedges will impact Occidental's earnings through mark-to-market until the offsetting future physical commodity is delivered. For GAAP purposes, any physical inventory is carried at lower of cost or market on the balance sheet. A substantial majority of Occidental's physical derivative contracts are index-based and carry no mark-to-market value in earnings. Net gains and losses associated with derivative instruments not designated as hedging instruments are recognized currently in net sales. Net gains and losses attributable to derivative instruments subject to hedge accounting reside in accumulated other comprehensive income (loss) and are reclassified to earnings as the transactions to which the derivatives relate are recognized in earnings.



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 would need to post. Occidental believes that if it had received a one-notch reduction in its credit ratings, it would not have resulted in a material change in its collateral-posting requirements as of March 31,June 30, 2018, and December 31, 2017.

Cash-Flow Hedges

Occidental’s marketing operations store natural gas purchased from third parties at Occidental’s leased storage facilities. Derivative instruments are used to fix margins on the future sales of the stored volumes. As of March 31,June 30, 2018, Occidental did not have any cash-flow hedges. As of December 31, 2017, Occidental had approximately 7 billion cubic feet (Bcf) of natural gas held in storage, and had cash-flow hedges for the forecast sales, to be settled by physical delivery, of approximately 7 Bcf of stored natural gas. The amount of cash-flow hedges, including the ineffective portion, was immaterial for the three months ended March 31, 2018, and the year ended December 31, 2017.


Derivatives Not Designated as Hedging Instruments

Forward unrealized instruments that are derivatives not designated as hedging instruments are required to be recorded on the income statement and balance sheet at fair value. The fair value represents an unrealized gain or loss between executed sales prices and market prices at the end of the period. The fair value does not reflect the realized or cash value of the instrument. Substantially all of the fair value of Occidental's derivative instruments not designated as hedges are used to manage its exposure to commodity price fluctuations and settle within three months at a weighted average sales price of $70.90 and $2.53 for crude oil and natural gas, respectively at June 30, 2018. The remaining fair value of derivative instruments not designated as hedges was immaterial. The weighted average sales price was $57.38 and $2.73 for crude oil and natural gas, respectively, at December 31, 2017.

The following table summarizes the amounts reported in net sales related to the outstanding commodity derivative instrumentsderivatives not designated as hedging instruments as of March 31,June 30, 2018 and December 31, 2017:2017.

(b)These amounts do not include collateral. As of March 31,June 30, 2018, no collateral received of $4 million has been netted against derivative assets and collateral paid of $32$40 million has been netted against derivative liabilities. As of December 31, 2017, no collateral received has been netted against derivative assets and collateral paid of $54 million has been netted against derivative liabilities. Select clearinghouse and brokers require Occidental to post an initial margin deposit. Collateral deposited by Occidental, mainly for initial margin, of $71$73 million and $53 million as of March 31,June 30, 2018 and December 31, 2017, respectively, has not been reflected in these derivative fair value tables. This collateral is included in other current assets in the consolidated condensed balance sheets.


12. Industry Segments

Occidental conducts its operations through three segments: (1) oil and gasgas; (2) chemicalchemical; and (3) 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 gathers, processes, transports, stores, purchases and markets oil, condensate, NGL, natural gas, CO2 and power. It also trades around its assets, including transportation and storage capacity. Additionally, the midstream and marketing segment invests in entities that conduct similar activities.

Results of industry segments generally exclude income taxes, interest income, interest expense, environmental remediation expenses, unallocated corporate expenses and discontinued operations, but include gains and losses from dispositions of segment and geographic area assets and income from the segments' equity investments. Intersegment sales eliminate upon consolidation and are generally made at prices approximating those that the selling entity would be able to obtain in third-party transactions.

13. Earnings Per Share

Basic earnings per share (EPS) was computed by dividing net income attributable to common stock, net of income allocated to participating securities, by the weighted-average number of common shares outstanding during each period, net of treasury shares and including vested but unissued shares and share units. The computation of diluted EPS reflects the additional dilutive effect of stock options and unvested stock awards. Occidental’s instruments containing rights to nonforfeitable dividends granted in stock-based awards are considered participating securities prior to vesting and, therefore, net income allocated to these participating securities has been deducted from earnings in computing basic and diluted EPS under the two-class method. The following table presents the calculation of basic and diluted EPS for the three and six months ended March 31,June 30, 2018, and 2017 (in millions, except per-share amounts):

TheDiluted earnings per share was $1.10 for the second quarter of 2018 compared to $0.66 for the second quarter of 2017.

Occidental reported net income of $1.6 billion for the six months ended June 30, 2018, on net sales of $7.8 billion, compared to net income of $624 million on net sales of $6.0 billion for the same period of 2017.

Net income increased for the three and six months ended June 30, 2018, when compared to the same periods of 2017, across all segments. Excluding the gain on sale of South Texas operations in the second quarter of 2017, approximately two-thirds of the increase in net income mainly reflectedearnings for the three and six months ended June 30, 2018, compared to the same periods of 2017, was the result of higher crude oil prices, higher domestic volumes, and volumeslower depreciation, depletion and amortization (DD&A) rates in the oil and gas segment, significant improvements in realized caustic soda prices in the chemical segment, andsegment. The remaining increase reflected higher marketing margins from improved crude oil price spreads and additional incremental margin earned from exporting crude oil fromin the Ingleside Crude Terminal andmarketing business as well as higher realized NGLcaustic soda prices from gas processing in the midstream and marketing segment. Diluted earnings per share was $0.92 for the first quarter of 2018 comparedfavorable plant margins due to $0.15 for the first quarter of 2017.lower ethylene and energy costs.

Selected Statements of Operations Items

Net sales increased for the three and six months ended March 31,June 30, 2018, compared to the same periodperiods in 2017, as a result of higher crude oil prices and higher domestic crude oil volumes in the oil and gas segment, higher realized caustic soda prices in the chemical segment and higher marketing margins from improved crude oil spreads.in the midstream and marketing segment. Gain on the sale of assets, net, totaling $512 million for the three and six months ended June 30, 2017, primarily reflected gains on sale of the South Texas operations.

Cost of sales decreased for the three and six months ended March 31,June 30, 2018, compared to the same periodperiods in 2017, mainly due to lower raw materials costs in the chemical segment and changes in the fair value of a long-term contract to purchase CO2. carbon dioxide in the oil and gas segment, partially offset by higher third party crude purchases.

The increase in selling, general and administrative and other operating expenses for the three and six months ended March 31,June 30, 2018, compared to the same periodperiods in 2017, reflected higher stock compensation costs partially due to the change in timing of stock-based incentive compensation awardsOccidental's higher stock price and improved stock price.higher environmental remediation costs. Taxes other than on income increased for the three and six months ended March 31,June 30, 2018, compared to the same periodperiods of 2017, mainly due to higher production taxes


as a result of higher domestic oil prices. The decrease in DD&A expense for the three and six months ended March 31,June 30, 2018, compared to the same periodperiods in 2017, was mainly due to lower DD&A rates in the Permian Resources oil and gas operations.

The increase in the domestic and foreign income tax provision for the three and six months ended March 31,June 30, 2018, compared to the same periodperiods in 2017, reflected higher pre-tax operating income inincome.

See “Liquidity and Capital Resources” for a discussion about the changes in cash and cash equivalents.
 
The increase in trade receivables, net, at March 31,June 30, 2018, compared to December 31, 2017, was primarily due to higher crude oil prices and volumes exported from the Ingleside crude terminal.volumes. The decreaseincrease in inventories at March 31,

Assets and liabilities held for sale primarily represent non-core midstream assets and non-core proved and unproved domestic acreage to be traded or sold as Occidental continues to streamline its Permian position.acreage. The reductionincrease in assets held for sale from December 31, 2017, is primarily the result of the addition of $1.5 billion in non-core upstream and midstream property, plant and equipment, partially offset by the divestiture of non-core Permian and midstream assets with a book value of $225 million, partially offset by additions$0.3 billion. Excluding the reclassification of $104 million in non-core proved Permian acreage. Theassets held for sale, the increase in property, plant and equipment, net at March 31,June 30, 2018, compared to December 31, 2017, is primarily the result of capital expenditures and property acquisitions of $1.0$2.3 billion and $169 million,$0.2 billion, respectively, which were partially offset by DD&A of $0.9 billion and the reclassification of property to assets held for sale of $104 million.$1.8 billion.

The decrease in the current portion of long-term debt at March 31,June 30, 2018, compared to December 31, 2017, reflected the repayment of $500 million of 1.5-percent senior notes that matured in February 2018. Accrued liabilitiesThe increase in accounts payable at March 31,June 30, 2018, compared to December 31, 2017, mainly reflected higher crude oil prices and third-party purchases. The increase in accrued liabilities at June 30, 2018, compared to December 31, 2017, mainly reflected mark-to-market increases on derivative financial instruments, partially offset by payments related to incentive compensation and ad valorem taxesthat were paid in the first quarter of 2018. Long-termThe increase in long-term debt at March 31,June 30, 2018, compared to December 31, 2017, reflected the issuance of $1.0 billion of 4.2-percent senior notes due 2048. The increase in deferred domestic and foreign income taxes at March 31,June 30, 2018, compared to December 31, 2017, was primarily due to accelerated depreciation for tax purposes.




Segment Operations
 
Occidental conducts its operations through three segments: (1) oil and gasgas; (2) chemicalchemical; and (3) 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 gathers, processes, transports, stores, purchases and markets oil, condensate, NGL, natural gas, CO2 and power. It also trades around its assets, including transportation and storage capacity. Additionally, the midstream and marketing segment invests in entities that conduct similar activities.

In 2017, Occidental recorded a provisional estimate for the federal and state income tax associated with the mandatory deemed repatriation, as required under the 2017 Tax Cuts and Jobs Act (Tax Reform), and the resulting impact to the net federal deferred tax liability. As of March 31,June 30, 2018, additional definitive technical guidance has been provided related to a portion of the provisional estimate made as of December 31, 2017. The additional guidance did not result in any change to the provisional estimates recorded as of December 31, 2017. However, the ultimate impact of Tax Reform may differ from Occidental’s estimates due to changes in interpretations and assumptions, as well as additional regulatory guidance.
Oil and Gas Segment
 
Oil and gas segment earnings were $750$780 million and $1.5 billion for the first quarter ofthree and six months ended June 30, 2018, respectively, compared with segment earnings of $220$627 million and $847 million for the first quartersame periods of 2017. The three and six months ended June 30, 2017, included a $510 million pre-tax gain, primarily on the sale of South Texas operations. Excluding the gain on sale, the increase in earnings primarilyfor the three and six months ended June 30, 2018, compared to the same periods in 2017, reflected significantly higher oil and NGL prices as both average WTI and Brent oil prices increased by over 2030 percent, in the three months ended March 31, 2018, compared to the same period in 2017,higher domestic volumes and lower DD&A rates, which had decreased by approximately 8 percent.



The following tables set forth the total production and sales volumes for oil, NGL and natural gas per day for the three and six months ended March 31,June 30, 2018, and 2017. The differences between the production and sales volumes per day are generally due to the timing of shipments at Occidental’s international locations, where the product is loaded onto tankers.

Occidental’s operations are subject to stringent federal, state, local and foreign 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 into its business planning process as an integral part of producing quality products responsive to market demand.

The laws that require or address environmental remediation, including CERCLA and similar federal, state, local and foreign laws, may apply retroactively and regardless of fault, the legality of the original activities or the current ownership or control of sites. OPC 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 of hazardous substances; or operation and maintenance of remedial systems. These 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.
