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 rates on forecasted debt issuances. Derivatives are carried at fair value and on a net basis when a legal right of offset exists with the same counterparty. See Note 1 - Summary of Significant Accounting Policies for Occidental’s accounting policy on derivatives.

Derivative instruments that are derivatives 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 realized or cash value of the instrument.

In 2019, Occidental entered into 2020 Brent-priced 3-way collars combined with 2021 call options on the same volume to manage its near-term exposure to cash flow variability from oil price risks in 2020. The 2021 call options were sold to enhance the upside retention in 2020. In 2020, management elected to hedge a portion of Occidental’s expected 2021 natural gas production to enhance cash flow stability. The majority of the collars settled in 2020 with the receipt of cash of $960 million. The remaining $52 million settled in 2021.The 2021 call options were entered into to substantially improve the terms for the ceiling price that Occidental received for the contracted commodity volumes in 2020.

sold call and a purchased put. The sold call establishes the ceiling price that Occidental will receive for the contracted commodity volume for a defined period of time. The purchased put establishes the floor price that Occidental will receive for the contracted volumes. Net gains and losses associated with collars and calls are recognized currently in net sales.

Occidental acquired interest rate swap contracts in the Acquisition. The contracts lock in a fixed interest rate in exchange for a floating interest rate indexed to three-month London Inter-Bank Offered Rate (LIBOR) throughout the reference period. Net gains and losses associated with interest rate derivative instruments not designated as hedging instruments are recognized currently in gains (losses) on interest rate swaps and warrants, net.

Depending on market conditions, liability management actions or other factors, Occidental may enter into offsetting interest rate swap positions or settle or amend certain or all of the currently outstanding interest rate swaps. Occidental settled interest rate swaps with a notional value of $125 million in October 2019. In the first quarter of 2020, Occidental extended all 2020 mandatory termination dates to 2021 or thereafter.

Derivative settlements and collateralization are classified as cash flows 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. Due to the liability position of the interest rate derivatives at the date of the Acquisition, the interest rate derivatives in Occidental’s portfolio contain an other-than-insignificant financing element, and therefore, any settlements, collateralization or cash payments related to interest rate derivatives are classified as cash flow from financing activities. Net cash payments related to settlements were $93 million for the twelve months ended December 31, 2020. Collateral with respect to interest rate swap agreements was paid in the amount of $270 million for the twelve months ended December 31, 2020.

Occidental’s marketing derivative instruments not designated as hedges are short-duration physical and financial forward contracts. A substantial majority of Occidental’s physically settled derivative contracts are index-based and carry no mark-to-market valuation in earnings. These instruments settle at a weighted-average contract price of $46.05 per barrel and $2.58 per Mcf for oil and natural gas, respectively, at December 31, 2020. The weighted-average contract price was $60.60 per barrel and $2.17 per Mcf for oil and natural gas, respectively, at December 31, 2019. Net gains and losses associated with marketing derivative instruments not designated as hedging instruments are recognized currently in net sales.

Warrants for 80 million shares of Occidental stock, with an initial exercise price of $62.50, were issued in connection with the financing of the Acquisition (the Berkshire Warrants). The Berkshire Warrants are exercisable at the holder’s option, in whole or in part, until the first anniversary of the date on which no shares of Preferred Stock remain outstanding, at which time the Berkshire Warrants expire. The holders of the Berkshire Warrants could have required net cash settlement if certain shareholder and regulatory approvals to issue shares of Occidental’s common stock underlying the Berkshire Warrants were not obtained. Prior to these approvals, the fair value of the Berkshire Warrants was remeasured each reporting date with gains and losses being recorded on the income statement.

At Occidental’s May 29, 2020 annual shareholders meeting, all remaining approvals were obtained and the Berkshire Warrants can no longer be cash settled. Upon these approvals, the fair value of the Berkshire Warrants was remeasured at May 29, 2020, using the Black-Scholes option model. The reclassification from liabilities to “Additional paid-in capital” was $103 million.

The following inputs were used in the Black-Scholes option model: the expected life of the Berkshire Warrants, a volatility factor and the exercise price. The expected life is based on the estimated term of the Berkshire Warrants, the volatility factor is based on historical volatilities of Occidental common stock and the initial exercise price of $62.50.

The Berkshire Warrants contain an anti-dilution provision that adjusts the exercise price and the number of shares of Occidental’s common stock issuable on exercise upon the occurrence of certain distributions to common shareholders. On June 26, 2020, Occidental’s Board of Directors declared a distribution to its common shareholders of warrants to purchase additional shares of common stock, See Note 13 - Stockholders ’ Equity. This distribution to common shareholders resulted in an anti-dilution adjustment to the Berkshire Warrants, which lowered its exercise price to $59.624 and increased the number of shares of Occidental’s common stock issuable on exercise of the Berkshire Warrants by approximately 3.9 million shares.

Net gains and losses attributable to derivative instruments subject to cash flow hedge accounting reside in accumulated other comprehensive loss and are reclassified to earnings as the transactions to which the derivatives relate, primarily interest expense on debt issued to partially finance the Acquisition, are recognized in earnings.

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 reported at the end of each reporting period. The following table presents the fair values of Occidental’s outstanding derivatives. Fair values are presented at gross amounts below, including when derivatives are subject to netting arrangements, and are presented on a net basis in the Consolidated Balance Sheets.

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 futures 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 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 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 December 31, 2020 was $104 million (net of $374 million collateral), primarily related to acquired interest rate swaps, and $787 million (net of $169 million of collateral) existed at December 31, 2019.
