NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

JUNE 30, 2015

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, 2014 .

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 June 30, 2015 , and the consolidated statements of operations, comprehensive income and cash flows for the three and six months ended June 30, 2015 and 2014 , as applicable. The income and cash flows for the periods ended June 30, 2015 and 2014 are not necessarily indicative of the income or cash flows to be expected for the full year.

As a result of the spin-off of California Resources Corporation (California Resources), the statements of operations and cash flows related to California Resources have been treated as discontinued operations for the three and six months ended June 30, 2014. The assets and liabilities of California Resources were removed from Occidental's consolidated balance sheet as of November 30, 2014. See Note 2, Asset Acquisitions, Dispositions and Other, for additional information.

2. Asset Acquisitions, Dispositions and Other

In June 2015, Occidental issued $1.5 billion of debt that was comprised of $750 million of 3.50-percent senior unsecured notes due 2025 and $750 million of 4.625-percent senior unsecured notes due 2045. Occidental received net proceeds of approximately $1.48 billion. Interest on the notes will be payable semi-annually in arrears in June and December of each year for both series of notes, beginning on December 15, 2015.

On November 30, 2014, the spin-off of Occidental's California oil and gas operations and related assets was completed through the distribution of 81.3 percent of the outstanding shares of common stock of California Resources to holders of Occidental common stock, creating an independent, publicly traded company. In connection with the spin-off, California Resources distributed to Occidental $4.95 billion in restricted cash and $1.15 billion in unrestricted cash. As indicated by a private letter ruling from the United States Internal Revenue Service (IRS), the $4.95 billion distribution must be used solely to pay dividends, repurchase common stock, repay debt, or a combination of the foregoing, within 18 months following the distribution. At June 30, 2015, the remaining balance of the restricted cash distribution was $2.4 billion and was presented as "Restricted cash" on the consolidated balance sheet. Occidental retained 71.5 million shares of California Resources. See Note 9, Fair Value Measurements, for additional information.

Sales and other operating revenues and income from discontinued operations related to California Resources for the three and six months ended June 30, 2014 were as follows (in millions):

3. Accounting and Disclosure Changes

In July 2015, the Financial Accounting Standards Board (FASB) voted to defer the effective date of the new revenue recognition standard to interim and annual periods beginning after December 15, 2017. Under the new rules, an entity will recognize revenue when it transfers promised goods or services to customers in an amount that reflects what it expects to receive in exchange for the goods and services. The rules also require more detailed disclosures related to the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The rules are not expected to have a significant impact on Occidental's financial statements upon adoption.

In May 2015, the FASB issued rules modifying how entities measure certain investments at net asset value as well as how they are categorized within the fair value hierarchy. The new rules remove the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value per share. The update also removes the requirement for certain disclosures for all investments that are eligible to be measured at fair value using the net asset value per share practice, and instead requires it for only those investments the entity elects to measure as such. The rules become effective for fiscal years, and for interim periods, beginning after December 15, 2015. The rules will not have a significant impact on Occidental's financial statements.

In April 2015, the FASB issued rules simplifying the presentation of debt issuance costs. The new rules require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The rules become effective for fiscal years, and for interim periods, beginning after December 15, 2015. The rules will not have a significant impact on Occidental's financial statements.

In February 2015, the FASB issued rules modifying how an entity should evaluate certain legal entities for consolidation. The modifications change how limited partnerships and similar legal entities are evaluated, eliminate the presumption that a general partner should consolidate limited partnerships, change the consolidation analysis for reporting entities that are involved with variable interest entities, and change the scope exception for certain legal entities, among other things. The rules become effective for fiscal years, and for interim periods, beginning after December 15, 2015. The rules are not expected to have an impact on Occidental's financial statements upon adoption.

In January 2015, the FASB issued rules that eliminate from GAAP the concept of an extraordinary item. The presentation and disclosure guidance for items that are unusual in nature or occur infrequently will be retained and expanded to include items that are both unusual in nature and infrequently occurring. The rules do not impact Occidental's financial statements upon adoption.

4. Supplemental Cash Flow Information

Occidental paid United States federal, state and foreign income taxes of $0.6 billion and $1.7 billion during the six months ended June 30, 2015 and 2014 , respectively. Interest paid totaled $108 million and $110 million for the six months ended June 30, 2015 and 2014 , respectively.

5. Inventories

A portion of inventories is valued under the LIFO method.  The valuation of LIFO inventory for interim periods is based on Occidental's estimates of year-end inventory levels and costs. Inventories as of June 30, 2015 and December 31, 2014 consisted of the following (in millions):

6. 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.  Government or private 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 June 30, 2015 , Occidental participated in or monitored remedial activities or proceedings at 147 sites.  The following table presents Occidental's environmental remediation reserves as of June 30, 2015 , the current portion which is included in accrued liabilities ($79 million) and the remainder in deferred credits and other liabilities - other ($237 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 June 30, 2015 , Occidental's environmental reserves exceeded $10 million each at 11 of the 147 sites described above, and 102 of the sites each had reserves of $1 million or less.  Based on current estimates, Occidental expects to expend funds corresponding to approximately half of the current 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 range of reasonably possible additional losses beyond those liabilities recorded for environmental remediation at these sites could be up to $395 million.  The status of Occidental's involvement with the sites and related significant assumptions has not changed materially since December 31, 2014 .  For additional

information regarding environmental matters, refer to Note 7, Lawsuits, Claims, Commitments and Contingencies, for additional information.

7. Lawsuits, Claims, Commitments and Contingencies

OPC 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.  OPC 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 OPC 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.

Occidental has entered into a written settlement agreement with the State of New Jersey (the State) to resolve claims asserted by the State against Occidental arising from Occidental's acquisition of Diamond Shamrock Chemicals Company (DSCC) and historic operations of DSCC's Lister Avenue Plant. In December 2014, the settlement was approved by the court. Under the settlement agreement (State Settlement) Occidental agreed to pay the State $190 million and, under certain circumstances, perform or fund future work on behalf of the State along a portion of the Passaic River. Occidental made payments related to this settlement of $70 million, $60 million and $60 million in February, April and June 2015, respectively. When Occidental acquired the stock of DSCC in 1986, Maxus Energy Corporation, a subsidiary of YPF S.A. (Maxus), retained liability for the Lister Avenue Plant, which is part of the Diamond Alkali Superfund Site, as well as other sites. Maxus is also obligated to indemnify Occidental for the State of New Jersey settlement. Occidental is pursuing Maxus to recover the settlement costs. The State Settlement does not cover any potential Occidental share of costs associated with the Environmental Protection Agency's proposed clean-up plan of the Passaic River announced in April 2014. Maxus is also responsible for federal clean-up or other costs associated with the Lister Avenue Plant and the Diamond Alkali Superfund Site.

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 matters.  Reserve balances for other matters as of June 30, 2015 and December 31, 2014 were not material to Occidental's consolidated balance sheets.  Occidental also evaluates the amount of reasonably possible losses that it could incur as a result of the matters mentioned above. Occidental has disclosed its range of reasonably possible additional losses for sites where it is a participant in environmental remediation.  Occidental believes that other reasonably possible losses that it could incur in excess of reserves accrued on the balance sheet would not be material to its consolidated financial position or results of operations.

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 2009 for United States federal income tax purposes have been audited by the IRS pursuant to its Compliance Assurance Program, subsequent taxable years are currently under review. Additionally, in December 2012, Occidental filed United States federal refund claims for tax years 2008 and 2009, which are subject to IRS review. Taxable years from 2000 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.

OPC, 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, 2015 , 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.

8. Retirement and Post-retirement Benefit Plans

The following tables set forth the components of the net periodic benefit costs for Occidental's defined benefit pension and post-retirement benefit plans for the three and six months ended June 30, 2015 and 2014 (in millions):

Occidental contributed approximately zero and $2 million to its defined benefit pension plans in the three-months ended June 30, 2015 and 2014 , respectively. Occidental contributed approximately $5 million and $3 million in the six-months ended June 30, 2015 and 2014, respectively.

9. 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

Occidental primarily applies the market approach for recurring fair value measurements, maximizes its use of observable inputs and minimizes its use of unobservable inputs. Occidental utilizes the mid-point between bid and ask prices for valuing the majority of its assets and liabilities measured and reported at fair value. In addition to using market data, Occidental makes assumptions in valuing its assets and liabilities, including assumptions about the risks inherent in the inputs to the valuation technique.  For assets and liabilities carried at fair value, Occidental measures fair value using the following methods:

that are generally unobservable in the marketplace, or are observable but have been adjusted based upon various assumptions and the fair value is designated as Level 3 within the valuation hierarchy.

Occidental generally uses an income approach to measure fair value when observable inputs are unavailable. This approach utilizes management's judgments regarding expectations of projected cash flows, and discounts those cash flows using a risk-adjusted discount rate.

The following tables provide fair value measurement information for such assets and liabilities that are measured on a recurring basis as of June 30, 2015 and December 31, 2014 (in millions):

Fair Values - Nonrecurring

During the three months ended June 30, 2015 and 2014 and the six months ended June 30, 2014, Occidental did not have any assets or liabilities measured at fair value on a non-recurring basis. As a result of lower commodity prices during the first quarter 2015, Occidental recognized approximately $160 million in pre-tax impairment charges related to proved domestic oil and gas properties.

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 June 30, 2015 and December 31, 2014 was $8.6 billion and $7.0 billion, respectively, and its carrying value net of unamortized discount as of June 30, 2015 and December 31, 2014 was $8.3 billion and $6.8 billion, respectively. The majority of Occidental's debt is classified as Level 1, with $68 million classified as Level 2.

10. Derivatives

Derivatives are carried at fair value and on a net basis when a legal right of offset exists with the same counterparty.  Occidental applies hedge accounting when transactions meet specified criteria for cash-flow hedge treatment and management elects and documents such treatment.  Otherwise, any fair value gains or losses are recognized in earnings in the current period.

Occidental uses a variety of derivative instruments, including cash-flow hedges and derivative instruments not designated as hedging instruments, to obtain average prices for the relevant production month and to improve realized prices for oil and gas. Occidental only occasionally hedges its oil and gas production, and, when it does, the volumes are usually insignificant.

Cash-Flow Hedges

Occidental's marketing and trading operations, from time to time, store natural gas purchased from third parties at Occidental's North American leased storage facilities. Derivative instruments are used to fix margins on the future sales of the stored volumes through February 2016. As of June 30, 2015, Occidental had approximately 9 billion cubic feet of natural gas held in storage, and had cash-flow hedges for the forecast sale, to be settled by physical delivery, of approximately 3 billion cubic feet of stored natural gas. As of December 31, 2014, Occidental did not have any cash-flow hedges.

Occidental's after-tax gains and losses recognized in, and reclassified to income from, Accumulated Other Comprehensive Income (AOCI) for derivative instruments classified as cash-flow hedges for the three and six months ended June 30, 2015 and 2014, and the ending AOCI balances for each period, were not material. The gains and losses reclassified to income were recognized in net sales, and the amount of the ineffective portion of cash-flow hedges was immaterial for the three and six months ended June 30, 2015 and 2014.

Derivatives Not Designated as Hedging Instruments

The following table summarizes Occidental's net volumes of outstanding commodity derivatives contracts not designated as hedging instruments, including both financial and physical derivative contracts as of June 30, 2015 and December 31, 2014 :

The volumes in the table above exclude contracts tied to index prices, for which the fair value, if any, is minimal at any point in time. These excluded contracts do not expose Occidental to price risk because the contract prices fluctuate with index prices.

Occidental fulfills short positions through its own production or by third-party purchase contracts. Subsequent to June 30, 2015 , Occidental entered into purchase contracts for a substantial portion of the short positions outstanding at quarter end and has sufficient production capacity and the ability to enter into additional purchase contracts to satisfy the remaining positions.

Approximately $45 million of net gains from derivatives not designated as hedging instruments and $72 million of net gains were recognized in net sales for the three months ended June 30, 2015 and 2014 , respectively. Approximately $44 million of net losses from derivatives not designated as hedging instruments and $84 million of net gains were recognized in net sales or the six months ended June 30, 2015 and 2014, respectively.

Fair Value of Derivatives

The following table presents the gross and net fair values of Occidental's outstanding derivatives as of June 30, 2015 and December 31, 2014 (in millions):

See Note 9, Fair Value Measurements, for fair value measurement disclosures on derivatives.

Credit Risk

A large portion of Occidental's derivative transaction volume is executed through the over-the-counter market. Occidental is subject to counterparty credit risk to the extent the counterparty to the derivatives is unable to meet its settlement commitments.  Occidental manages this credit risk by selecting counterparties that it believes to be financially strong, by spreading the credit risk among many such counterparties, by entering into master netting arrangements with the counterparties and by requiring collateral, as appropriate.  Occidental actively monitors the creditworthiness of each counterparty and records valuation adjustments to reflect counterparty risk, if necessary. Occidental executes the rest of its derivative transactions in the exchange-traded market, which are subject to minimal credit risk as a significant portion of these transactions is settled on a daily margin basis with select clearinghouses and brokers.  

Certain of Occidental's OTC 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.  As of June 30, 2015 and December 31, 2014 , Occidental had a net liability of zero and $4 million, respectively, which is net of collateral posted of zero and $3 million, respectively.  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 June 30, 2015 and December 31, 2014 .

11. Industry Segments

Occidental conducts its operations through three segments: (1) oil and gas; (2) chemical; and (3) midstream and marketing. The oil and gas segment explores for, develops and produces oil and condensate, natural gas liquids (NGLs) 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, NGLs, natural gas, carbon dioxide (CO 2 ) and power.  It also trades around its assets, including transportation and storage capacity, and trades oil, NGLs, gas and power. Additionally, the midstream and marketing segment invests in entities that conduct similar activities.

Earnings 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 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.

The following tables present Occidental's industry segments (in millions):

(a) Includes pre-tax charges of $310 million for the impairment of certain domestic and international oil and gas assets and other items and $14 million of other corporate items.

(b) Includes unallocated net interest expense, administration expense, environmental remediation and other pre-tax items.

(c) Includes all foreign and domestic income taxes from continuing operations.

12. Earnings Per Share

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.

Basic 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.

The following table presents the calculation of basic and diluted EPS for the three and six months ended June 30, 2015 and 2014 (in millions, except per-share amounts):
