Financial Risk Management Activities
20.  Financial Risk Management Activities
In the normal course of our business, we are exposed to commodity risks related to changes in the prices of crude oil and natural gas, as well as changes in interest rates and foreign currency values.  In the disclosures that follow, corporate financial risk management activities refer to the mitigation of these risks through hedging activities.  We maintain a control environment for all of our financial risk management activities under the direction of our Chief Risk Officer.  Our Treasury department is responsible for administering foreign exchange rate and interest rate hedging programs using similar controls and processes, where applicable.  Hedging strategies are reviewed annually by the Audit Committee of the Board of Directors.
Corporate Financial Risk Management Activities: Financial risk management activities include transactions designed to reduce risk in the selling prices of crude oil or natural gas we produce or by reducing our exposure to foreign currency or interest rate movements.  Generally, futures, swaps or option strategies may be used to fix the forward selling price of a portion of our crude oil or natural gas production.  Swaps may also be used to fix the difference between current selling prices and forward selling prices in periods of contango for crude oil production that will be stored and sold in the future. Forward contracts may also be used to purchase certain currencies in which we conduct business with the intent of reducing exposure to foreign currency fluctuations.  At December 31, 2020, these forward contracts relate to the British Pound, Danish Krone, Canadian Dollar and Malaysian Ringgit.  Interest rate swaps may be used to convert interest payments on certain long-term debt from fixed to floating rates.
The notional amounts of outstanding financial risk management derivative contracts were as follows:

At December 31, 2020, we had WTI put options with an average monthly floor price of approximately $45 per barrel for 75,000 bopd for 2021. In the first quarter of 2021, we increased the average monthly floor price of 75,000 bopd of WTI put option contracts from approximately $45 per barrel to $50 per barrel for the remainder of 2021. We also purchased additional WTI put options with an average monthly floor price of $50 per barrel for 45,000 bopd and Brent put options with an average monthly floor price of $55 per barrel for 30,000 bopd. As a result, we now have total purchased WTI put options of 120,000 bopd with an average monthly floor price of $50 per barrel and total purchased Brent put options of 30,000 bopd with an average monthly floor price of $55 per barrel for the remainder of 2021.

In 2020, we chartered three VLCCs to load and transport a total of 6.3 million barrels of Bakken crude oil for sale in Asian markets. The first VLCC cargo of 2.1 million barrels was sold in September 2020. We have entered into agreements for the sale of the remaining 4.2 million barrels of crude oil in the first quarter of 2021. In connection with this activity, we entered into Brent swap transactions intended to fix the difference between Brent prices in the month of production and the forward Brent price for the expected month of sale. At December 31, 2020, net realized and unrealized losses from the Brent swaps of $16 million were deferred in Accumulated other comprehensive income, and the liability for unrealized losses from the Brent swaps was $54 million. In addition, total net realized gains from WTI put options associated with the VLCCs of $40 million were deferred in Accumulated other comprehensive income at December 31, 2020.
The fair value of our crude oil put options and crude oil swaps is presented within Other current assets and Accrued liabilities, respectively, in our Consolidated Balance Sheet. The fair value of our interest rate swaps is presented within Other assets in our Consolidated Balance Sheet. The fair value of our foreign exchange forwards is presented within Accrued liabilities in our Consolidated Balance Sheet. All fair values in the table above are based on Level 2 inputs.
Derivative contracts designated as hedging instruments:
Crude oil derivatives: In 2020, crude oil price hedging contracts increased Sales and other operating revenues by $547 million (2019: increase of $1 million; 2018: decrease of $161 million). At December 31, 2020, pre-tax deferred gains in Accumulated other comprehensive income (loss) related to outstanding crude oil price hedging contracts were $4 million, of which all will be reclassified into earnings during the next 12 months as the hedged crude oil sales are recognized in earnings.
Interest rate swaps designated as fair value hedges:  At December 31, 2020, we had interest rate swaps with gross notional amounts of $100 million (2019: $100 million), which were designated as fair value hedges and relate to long-term debt where we have converted interest payments from fixed to floating rates.  Changes in the fair value of interest rate swaps and the hedged fixed‑rate debt are recorded in Interest expense in the Statement of Consolidated Income.  In 2020, the change in fair value of interest rate swaps was an increase in the asset of $4 million (2019: $3 million decrease in liability; 2018: $1 million increase in liability) with a corresponding adjustment in the carrying value of the hedged fixed‑rate debt.
Derivative contracts not designated as hedging instruments:
Foreign exchange:  Total foreign exchange gains and losses were losses of $6 million in 2020 (2019: gain of $3 million; 2018: loss of $5 million) and are reported in Other, net in Revenues and non-operating income in the Statement of Consolidated Income.  A
component of foreign exchange gains or losses is the result of foreign exchange derivative contracts that are not designated as hedges, which amounted to a gain of $2 million in 2020 (2019: loss of $2 million; 2018: loss of $2 million).
Crude oil collars: In 2018, noncash adjustments to de-designated crude oil price hedging contracts decreased Sales and other operating revenues by $22 million.
Credit Risk: We are exposed to credit risks that may at times be concentrated with certain counterparties, groups of counterparties or customers.  Accounts receivable are generated from a diverse domestic and international customer base.  At December 31, 2020, our Accounts receivable were concentrated with the following counterparty industry segments:  Integrated companies — 39%, Independent E&P companies — 39%, Refining and marketing companies — 8%,  National oil companies — 5%, Storage and transportation companies — 5%, and Others — 4%.  We reduce risk related to certain counterparties, where applicable, by using master netting arrangements and requiring collateral, generally cash or letters of credit.
At December 31, 2020, we had outstanding letters of credit totaling $269 million (2019: $272 million).
Fair Value Measurement: At December 31, 2020, our total long-term debt, which was substantially comprised of fixed rate debt instruments, had a carrying value of $8,296 million and a fair value of $9,647 million, based on Level 2 inputs in the fair value measurement hierarchy.  We also have short-term financial instruments, primarily cash equivalents, accounts receivable and accounts payable, for which the carrying value approximated fair value at December 31, 2020 and December 31, 2019.
