Notes to Consolidated Financial Statements Phillips 66

Note 1—Interim Financial Information

The unaudited interim financial information presented in the financial statements included in this report is prepared in accordance with generally accepted accounting principles in the United States (GAAP) and includes all known accruals and adjustments necessary, in the opinion of management, for a fair presentation of the consolidated financial position of Phillips 66 and its results of operations and cash flows for the periods presented. Unless otherwise specified, all such adjustments are of a normal and recurring nature. Certain notes and other information have been condensed or omitted from the interim financial statements included in this report. Therefore, these interim financial statements should be read in conjunction with the consolidated financial statements and notes included in our 2021 Annual Report on Form 10-K. The results of operations for the three months ended March 31, 2022, are not necessarily indicative of the results expected for the full year.

On March 9, 2022, we completed the previously announced merger between us and Phillips 66 Partners LP (Phillips 66 Partners). See Note 18—Phillips 66 Partners LP, for additional information on the merger transaction.

Contract-Related Assets and Liabilities

At March 31, 2022, and December 31, 2021, receivables from contracts with customers were $8,604 million and $6,140 million, respectively. Significant noncustomer balances, such as buy/sell receivables and excise tax receivables, were excluded from these amounts.

Our contract-related assets also include payments we make to our marketing customers related to incentive programs. An incentive payment is initially recognized as an asset and subsequently amortized as a reduction to revenue over the contract term, which generally ranges from 5 to 15 years. At March 31, 2022, and December 31, 2021, our asset balances related to such payments were $471 million and $466 million, respectively.

Our contract liabilities represent advances from our customers prior to product or service delivery. At March 31, 2022, and December 31, 2021, contract liabilities were not material.

Remaining Performance Obligations

Most of our contracts with customers are spot contracts or term contracts with only variable consideration. We do not disclose remaining performance obligations for these contracts as the expected duration is one year or less or because the variable consideration has been allocated entirely to an unsatisfied performance obligation. We also have certain contracts in our Midstream segment that include minimum volume commitments with fixed pricing. At March 31, 2022, the remaining performance obligations related to these minimum volume commitment contracts were immaterial.

Note 3—Credit Losses

We are exposed to credit losses primarily through our sales of refined petroleum products, crude oil and NGL. We assess each counterparty’s ability to pay for the products we sell by conducting a credit review. The credit review considers our expected billing exposure and timing for payment and the counterparty’s established credit rating or our assessment of the counterparty’s creditworthiness based on our analysis of their financial statements when a credit rating is not available. We also consider contract terms and conditions, country and political risk, and business strategy in our evaluation. A credit limit is established for each counterparty based on the outcome of this review. We may require collateralized asset support or a prepayment to mitigate credit risk.

We monitor our ongoing credit exposure through active review of counterparty balances against contract terms and due dates. Our activities include timely account reconciliations, dispute resolution and payment confirmations. We may employ collection agencies and legal counsel to pursue recovery of defaulted receivables. In addition, when events and circumstances arise that may affect certain counterparties’ abilities to fulfill their obligations, such as Coronavirus Disease 2019 (COVID-19), we enhance our credit monitoring, and we may seek collateral to support some transactions or require prepayments from higher-risk counterparties.

At March 31, 2022, and December 31, 2021, we reported $10,455 million and $7,470 million of accounts and notes receivable, respectively, net of allowances of $44 million for both periods. Based on an aging analysis at March 31, 2022, more than 95% of our accounts receivable were outstanding less than 60 days.

We are also exposed to credit losses from off-balance sheet exposures, such as guarantees of joint venture debt and standby letters of credit. See Note 9—Guarantees, and Note 10—Contingencies and Commitments, for more information on these off-balance sheet exposures.

Note 4—Inventories

Inventories consisted of the following:

	Millions of Dollars
	March 31 2022		December 31 2021
Crude oil and petroleum products	$	4,152	3,024
Materials and supplies	378		370
	$	4,530	3,394

Inventories valued on the last-in, first-out (LIFO) basis totaled $3,923 million and $2,792 million at March 31, 2022, and December 31, 2021, respectively. The estimated excess of current replacement cost over LIFO cost of inventories amounted to approximately $9.4 billion and $5.7 billion at March 31, 2022, and December 31, 2021, respectively.

Certain planned reductions in inventory that are not expected to be replaced by the end of the year cause liquidations of LIFO inventory values. LIFO inventory liquidations increased our net income by $40 million in the three months ended March 31, 2022 and increased our net loss by $28 million in the three months ended March 31, 2021.

Note 5—Investments, Loans and Long-Term Receivables

Equity Investments

Dakota Access, LLC (Dakota Access) and Energy Transfer Crude Oil Company, LLC (ETCO)

In 2020, the trial court presiding over litigation brought by the Standing Rock Sioux Tribe ordered the U.S. Army Corps of Engineers (USACE) to prepare an Environmental Impact Statement (EIS) addressing an easement under Lake Oahe in North Dakota. The court later vacated the easement. Although the easement is vacated, the USACE has indicated that it will not take action to stop pipeline operations while it proceeds with the EIS. In May 2021, the Standing Rock Sioux Tribe’s request for an injunction to force a shutdown of the pipeline while the EIS is being prepared was denied. In June 2021, the trial court dismissed the litigation entirely. Once the EIS is completed, new litigation or challenges to the EIS could be filed.

In September 2021, Dakota Access filed a writ of certiorari, requesting the U.S. Supreme Court to review the lower court’s decision to order the EIS and vacate the easement. In February 2022, the writ was denied, and the requirement to prepare the EIS stands. Completion of the EIS was expected in the fall of 2022, but now may be delayed as the USACE engages with the Standing Rock Sioux Tribe on their reasons for withdrawing as a cooperating agency with respect to preparation of the EIS.

Dakota Access and ETCO have guaranteed repayment of senior unsecured notes issued by a wholly owned subsidiary of Dakota Access with an aggregate principal outstanding of $2.5 billion at March 31, 2022. In addition, Phillips 66 Partners, now a wholly owned subsidiary of Phillips 66, and its co-venturers in Dakota Access provided a Contingent Equity Contribution Undertaking (CECU) in conjunction with the notes offering. Under the CECU, the co-venturers may be severally required to make proportionate equity contributions to Dakota Access if there is an unfavorable final judgment in the above-mentioned ongoing litigation. At March 31, 2022, our share of the maximum potential equity contributions under the CECU was approximately $631 million.

If the pipeline is required to cease operations, and should Dakota Access and ETCO not have sufficient funds to pay ongoing expenses, we could be required to support our share of the ongoing expenses, including scheduled interest payments on the notes of approximately $25 million annually, in addition to the potential obligations under the CECU at March 31, 2022.

At March 31, 2022, the aggregate book value of our investments in Dakota Access and ETCO was $725 million.

On April 1, 2022, Dakota Access’ wholly owned subsidiary repaid $650 million aggregate principal amount of its outstanding senior notes upon maturity. We funded our 25% share, or $163 million, with a capital contribution of $89 million in March 2022 and $74 million of distributions we elected not to receive from Dakota Access in the first quarter of 2022. As a result of the debt repayment, on April 1, 2022, our share of the maximum potential equity contributions under the CECU decreased to approximately $467 million, and our share of scheduled interest payments on the notes that we could be required to support decreased to approximately $20 million annually.

CF United LLC (CF United)

We hold a 50% voting interest and a 48% economic interest in CF United, a retail marketing joint venture with operations primarily on the U.S. West Coast. CF United is considered a variable interest entity (VIE) because our co-venturer has an option to require us to purchase its interest based on a fixed multiple. The put option becomes effective July 1, 2023, and expires on March 31, 2024. The put option is viewed as a variable interest as the purchase price on the exercise date may not represent the then-current fair value of CF United. We have determined that we are not the primary beneficiary because we and our co-venturer jointly direct the activities of CF United that most significantly impact economic performance. At March 31, 2022, our maximum exposure to loss was comprised of our $278 million investment in CF United, and any potential future loss resulting from the put option should the purchase price based on a fixed multiple exceed the then-current fair value of CF United.

9

OnCue Holdings, LLC (OnCue)

We hold a 50% interest in OnCue, a joint venture that owns and operates retail convenience stores. We fully guaranteed various debt agreements of OnCue and our co-venturer did not participate in the guarantees. This entity is considered a VIE because our debt guarantees resulted in OnCue not being exposed to all potential losses. We have determined we are not the primary beneficiary because we do not have the power to direct the activities that most significantly impact economic performance. At March 31, 2022, our maximum exposure to loss was $188 million, which represented the book value of our investment in OnCue of $120 million and guaranteed debt obligations of $68 million.

Liberty Pipeline LLC (Liberty)

In the first quarter of 2021, Phillips 66 Partners decided to exit the Liberty Pipeline project, which resulted in a $198 million before-tax impairment in our Midstream segment. The impairment is included in the “Impairments” line item on our consolidated statement of operations for the three months ended March 31, 2021. See Note 12—Fair Value Measurements, for additional information regarding this impairment and the techniques used to determine the fair value of this investment. In April 2021, Phillips 66 Partners transferred its ownership interest in Liberty to its co-venturer for cash and certain pipeline assets with a value that approximated its book value of $46 million at March 31, 2021.

Other Investments

In September 2021, we acquired 78 million ordinary shares, representing a 16% ownership interest, in NOVONIX Limited (NOVONIX), which are traded on the Australian Securities Exchange. NOVONIX is a Brisbane, Australia-based company that develops technology and supplies materials for lithium-ion batteries. Since we do not have significant influence over the operating and financial policies of NOVONIX and the shares we own have a readily determinable fair value, our investment is recorded at fair value at the end of each reporting period. The fair value of our investment is recorded in the “Investments and long-term receivables” line item on our consolidated balance sheet. The change in the fair value of our investment due to fluctuations in NOVONIX’s stock price, or unrealized investment gains (losses), is recorded in the “Other income (loss)” line item of our consolidated statement of operations, while changes due to foreign currency fluctuations are recorded in the “Foreign currency transaction gains” line item on our consolidated statement of operations. The fair value of our investment in NOVONIX was $362 million at March 31, 2022. The fair value of our investment in NOVONIX declined by $158 million during the three months ended March 31, 2022, reflecting an unrealized investment loss of $169 million, partially offset by an unrealized foreign currency gain of $11 million. See Note 12—Fair Value Measurements, for additional information regarding the recurring fair value measurement of our investment in NOVONIX.

Related Party Loans

We and our co-venturer provided member loans to WRB Refining LP (WRB). At March 31, 2022, our 50% share of the outstanding member loan balance, including accrued interest, was $597 million.

Note 7—Earnings (Loss) Per Share

The numerator of basic earnings (loss) per share (EPS) is net income (loss) attributable to Phillips 66, adjusted for noncancelable dividends paid on unvested share-based employee awards during the vesting period (participating securities). The denominator of basic EPS is the sum of the daily weighted-average number of common shares outstanding during the periods presented and fully vested stock and unit awards that have not yet been issued as common stock. The numerator of diluted EPS is also based on net income (loss) attributable to Phillips 66, which is reduced by dividend equivalents paid on participating securities for which the dividends are more dilutive than the participation of the awards in the earnings (loss) of the periods presented. To the extent unvested stock, unit or option awards and vested unexercised stock options are dilutive, they are included with the weighted-average common shares outstanding in the denominator. Treasury stock is excluded from the denominator in both basic and diluted EPS.

On March 9, 2022, we completed the previously announced merger between us and Phillips 66 Partners. The merger resulted in the acquisition of all limited partnership interests in Phillips 66 Partners not already owned by us in exchange for approximately 42 million shares of Phillips 66 common stock issued from treasury stock. See Note 18—Phillips 66 Partners LP, for additional information on the merger transaction.

Note 8—Debt

2022 Activities

Debt Repayments

In early April 2022, upon maturity, Phillips 66 repaid its 4.300% senior notes with an aggregate principal amount of $1.0 billion and Phillips 66 Partners repaid its $450 million term loan.

Debt Exchange

On April 6, 2022, Phillips 66 Company, a wholly owned subsidiary of Phillips 66, announced offers to exchange (the Exchange Offers) all validly tendered notes of seven different series of notes issued by Phillips 66 Partners (collectively, the Old Notes), with an aggregate principal amount of approximately $3.5 billion, for notes to be issued by Phillips 66 Company (collectively, the New Notes). The New Notes will be fully and unconditionally guaranteed by Phillips 66 and will rank equally with Phillips 66 Company’s other unsecured and unsubordinated indebtedness, and the guarantees will rank equally with Phillips 66’s other unsecured and unsubordinated indebtedness. The Exchange Offers will expire on May 3, 2022, unless such date is extended (the Expiration Date). Phillips 66 Company currently expects the settlement of the Exchange Offers to occur on May 5, 2022, unless the Expiration Date is extended.

The New Notes will have the same interest rates, interest payment dates and maturity dates as the Old Notes. In addition, holders that validly tender before the end of the early participation period on April 19, 2022 (the Early Participation Date), will receive New Notes with an aggregate principal amount equivalent to the Old Notes, while holders that validly tender after the Early Participation Date, but before the Expiration Date, will receive New Notes with an aggregate principal amount that is 3% less than the Old Notes.

Through the end of the early participation period on April 19, 2022, Old Notes with an aggregate principal amount of approximately $3.2 billion had been validly tendered for exchange.

2021 Activities

In February 2021, Phillips 66 repaid $500 million outstanding principal balance of its floating-rate senior notes upon maturity.

Note 9—Guarantees

At March 31, 2022, we were liable for certain contingent obligations under various contractual arrangements as described below. We recognize a liability for the fair value of our obligation as a guarantor for newly issued or modified guarantees. Unless the carrying amount of the liability is noted below, we have not recognized a liability either because the guarantees were issued prior to December 31, 2002, or because the fair value of the obligation is immaterial. In addition, unless otherwise stated, we are not currently performing with any significance under the guarantees and expect future performance to be either immaterial or have only a remote chance of occurrence.

Lease Residual Value Guarantees

Under the operating lease agreement for our headquarters facility in Houston, Texas, we have the option, at the end of the lease term in September 2025, to request to renew the lease, purchase the facility or assist the lessor in marketing it for resale. We have a residual value guarantee associated with the operating lease agreement with a maximum potential future exposure of $514 million at March 31, 2022. We also have residual value guarantees associated with railcar and airplane leases with maximum potential future exposures totaling $221 million. These leases have remaining terms of up to ten years.

Guarantees of Joint Venture Obligations

In March 2019, Phillips 66 Partners and its co-venturers in Dakota Access provided a CECU in conjunction with a senior unsecured notes offering. See Note 5—Investments, Loans and Long-Term Receivables, for additional information on Dakota Access and the CECU.

At March 31, 2022, we also had other guarantees outstanding primarily for our portion of certain joint venture debt, which have remaining terms of up to four years. The maximum potential future exposures under these guarantees were approximately $133 million. Payment would be required if a joint venture defaults on its obligations.

Indemnifications

Over the years, we have entered into various agreements to sell ownership interests in certain corporations, joint ventures and assets that gave rise to indemnification. Agreements associated with these sales include indemnifications for taxes, litigation, environmental liabilities, permits and licenses, employee claims, and real estate tenant defaults. The provisions of these indemnifications vary greatly. The majority of these indemnifications are related to environmental issues, which generally have indefinite terms and potentially unlimited exposure. At March 31, 2022, and December 31, 2021, the carrying amount of recorded indemnifications was $146 million and $144 million, respectively.

We amortize the indemnification liability over the relevant time period, if one exists, based on the facts and circumstances surrounding each type of indemnity. In cases where the indemnification term is indefinite, we will reverse the liability when we have information to support the reversal. Although it is reasonably possible future payments may exceed amounts recorded, due to the nature of the indemnifications, it is not possible to make a reasonable estimate of the maximum potential amount of future payments. At March 31, 2022, and December 31, 2021, environmental accruals for known contamination of $109 million and $106 million, respectively, were included in the carrying amount of the recorded indemnifications noted above. These environmental accruals were primarily included in the “Asset retirement obligations and accrued environmental costs” line item on our consolidated balance sheet. For additional information about environmental liabilities, see Note 10—Contingencies and Commitments.

Indemnification and Release Agreement

In 2012, in connection with our separation from ConocoPhillips, we entered into an Indemnification and Release Agreement. This agreement governs the treatment between ConocoPhillips and us of matters relating to indemnification, insurance, litigation responsibility and management, and litigation document sharing and cooperation arising in connection with the separation. Generally, the agreement provides for cross indemnities principally designed to place financial responsibility for the obligations and liabilities of our business with us and financial responsibility for the obligations and liabilities of ConocoPhillips’ business with ConocoPhillips. The agreement also establishes procedures for handling claims subject to indemnification and related matters.

14

Note 10—Contingencies and Commitments

A number of lawsuits involving a variety of claims that arose in the ordinary course of business have been filed against us or are subject to indemnifications provided by us. We also may be required to remove or mitigate the effects on the environment of the placement, storage, disposal or release of certain chemical, mineral and petroleum substances at various active and inactive sites. We regularly assess the need for financial recognition or disclosure of these contingencies. In the case of all known contingencies (other than those related to income taxes), we accrue a liability when the loss is probable and the amount is reasonably estimable. If a range of amounts can be reasonably estimated and no amount within the range is a better estimate than any other amount, then the minimum of the range is accrued. We do not reduce these liabilities for potential insurance or third-party recoveries. If applicable, we accrue receivables for probable insurance or other third-party recoveries. In the case of income tax-related contingencies, we use a cumulative probability-weighted loss accrual in cases where sustaining a tax position is uncertain.

Based on currently available information, we believe it is remote that future costs related to known contingent liability exposures will exceed current accruals by an amount that would have a material adverse impact on our consolidated financial statements. As we learn new facts concerning contingencies, we reassess our position both with respect to accrued liabilities and other potential exposures. Estimates particularly sensitive to future changes include contingent liabilities recorded for environmental remediation, tax and legal matters. Estimated future environmental remediation costs are subject to change due to such factors as the uncertain magnitude of cleanup costs, the unknown time and extent of such remedial actions that may be required, and the determination of our liability in proportion to that of other potentially responsible parties. Estimated future costs related to tax and legal matters are subject to change as events evolve and as additional information becomes available during the administrative and litigation processes.

Environmental

We are subject to international, federal, state and local environmental laws and regulations. When we prepare our consolidated financial statements, we record accruals for environmental liabilities based on management’s best estimates, using information available at the time. We measure estimates and base contingent liabilities on currently available facts, existing technology and presently enacted laws and regulations, taking into account stakeholder and business considerations. When measuring contingent environmental liabilities, we also consider our prior experience in remediation of contaminated sites, other companies’ cleanup experience, and data released by the EPA or other organizations. We consider unasserted claims in our determination of environmental liabilities, and we accrue them in the period they are both probable and reasonably estimable.

Although liability for environmental remediation costs is generally joint and several for federal sites and frequently so for state sites, we are usually only one of many companies alleged to have liability at a particular site. Due to such joint and several liabilities, we could be responsible for all cleanup costs related to any site at which we have been designated as a potentially responsible party. We have been successful to date in sharing cleanup costs with other financially sound companies. Many of the sites for which we are potentially responsible are still under investigation by the EPA or the state agencies concerned. Prior to actual cleanup, those potentially responsible normally assess the site conditions, apportion responsibility and determine the appropriate remediation. In some instances, we may have no liability or may attain a settlement of liability. Where it appears that other potentially responsible parties may be financially unable to bear their proportional share, we consider this inability in estimating our potential liability, and we adjust our accruals accordingly. As a result of various acquisitions in the past, we assumed certain environmental obligations. Some of these environmental obligations are mitigated by indemnifications made by others for our benefit, although some of the indemnifications are subject to dollar and time limits.

We are currently participating in environmental assessments and cleanups at numerous federal Superfund and comparable state sites. After an assessment of environmental exposures for cleanup and other costs, we make accruals on an undiscounted basis (except those pertaining to sites acquired in a business combination, which we record on a discounted basis) for planned investigation and remediation activities for sites where it is probable future costs will be incurred and these costs can be reasonably estimated. At March 31, 2022, and December 31, 2021, our total environmental accruals were $436 million. We expect to incur a substantial amount of these expenditures within the next 30 years. We have not reduced these accruals for possible insurance recoveries. In the future, we may be involved in additional environmental assessments, cleanups and proceedings.

15

Legal Proceedings

Our legal organization applies its knowledge, experience and professional judgment to the specific characteristics of our cases, employing a litigation management process to manage and monitor the legal proceedings against us. Our process facilitates the early evaluation and quantification of potential exposures in individual cases and enables the tracking of those cases that have been scheduled for trial and/or mediation. Based on professional judgment and experience in using these litigation management tools and available information about current developments in all our cases, our legal organization regularly assesses the adequacy of current accruals and determines if adjustment of existing accruals, or establishment of new accruals, is required.

Other Contingencies

We have contingent liabilities resulting from throughput agreements with pipeline and processing companies not associated with financing arrangements. Under these agreements, we may be required to provide any such company with additional funds through advances and penalties for fees related to throughput capacity not utilized.

At March 31, 2022, we had performance obligations secured by letters of credit and bank guarantees of $1,546 million related to various purchase and other commitments incident to the ordinary conduct of business.

Note 11—Derivatives and Financial Instruments

Derivative Instruments

We use financial and commodity-based derivative contracts to manage exposures to fluctuations in commodity prices, interest rates and foreign currency exchange rates, or to capture market opportunities. Because we do not apply hedge accounting for commodity derivative contracts, all realized and unrealized gains and losses from commodity derivative contracts are recognized in our consolidated statement of operations. Gains and losses from derivative contracts held for trading not directly related to our physical business are reported net in the “Other income” line item on our consolidated statement of operations. Cash flows from all our derivative activity for the periods presented appear in the operating section on our consolidated statement of cash flows.

Purchase and sales contracts with firm minimum notional volumes for commodities that are readily convertible to cash are recorded on our consolidated balance sheet as derivatives unless the contracts are eligible for, and we elect, the normal purchases and normal sales exception, whereby the contracts are recorded on an accrual basis. We generally apply the normal purchases and normal sales exception to eligible crude oil, refined petroleum product, NGL, natural gas, renewable feedstock, and power commodity contracts to purchase or sell quantities we expect to use or sell in the normal course of business. All other derivative instruments are recorded at fair value on our consolidated balance sheet. For further information on the fair value of derivatives, see Note 12—Fair Value Measurements.

Commodity Derivative Contracts—We sell into or receive supply from the worldwide crude oil, refined petroleum product, NGL, natural gas, renewable feedstock, and electric power markets, exposing our revenues, purchases, cost of operating activities and cash flows to fluctuations in the prices for these commodities. Generally, our policy is to remain exposed to the market prices of commodities; however, we use futures, forwards, swaps and options in various markets to balance physical systems, meet customer needs, manage price exposures on specific transactions, and do a limited amount of trading not directly related to our physical business, all of which may reduce our exposure to fluctuations in market prices. We also use the market knowledge gained from these activities to capture market opportunities such as moving physical commodities to more profitable locations, storing commodities to capture seasonal or time premiums, and blending commodities to capture quality upgrades.

16

The following table indicates the consolidated balance sheet line items that include the fair values of commodity derivative assets and liabilities. The balances in the following table are presented on a gross basis, before the effects of counterparty and collateral netting. However, we have elected to present our commodity derivative assets and liabilities with the same counterparty on a net basis on our consolidated balance sheet when the legal right of offset exists.

At March 31, 2022, and December 31, 2021, there was no material cash collateral received or paid that was not offset on our consolidated balance sheet.

The realized and unrealized gains (losses) incurred from commodity derivatives, and the line items where they appear on our consolidated statement of operations, were:

	Millions of Dollars
	Three Months Ended March 31

The following table summarizes our material net exposures resulting from outstanding commodity derivative contracts. These financial and physical derivative contracts are primarily used to manage price exposure on our underlying operations. The underlying exposures may be from nonderivative positions such as inventory volumes. Financial derivative contracts may also offset physical derivative contracts, such as forward purchase and sales contracts. The percentage of our derivative contract volumes expiring within the next 12 months was more than 95% at March 31, 2022, and December 31, 2021.

	March 31 2022	December 31 2021
Commodity
Crude oil, refined petroleum products, NGL and renewable feedstocks (millions of barrels)	(27)	(18)

Credit Risk from Derivative Instruments

The credit risk from our derivative contracts, such as forwards and swaps, derives from the counterparty to the transaction. Individual counterparty exposure is managed within predetermined credit limits and includes the use of cash-call margins when appropriate, thereby reducing the risk of significant nonperformance. We also use futures, swaps and option contracts that have a negligible credit risk because these trades are cleared with an exchange clearinghouse and subject to mandatory margin requirements, typically on a daily basis, until settled.

Certain of our derivative instruments contain provisions that require us to post collateral if the derivative exposure exceeds a threshold amount. We have contracts with fixed threshold amounts and other contracts with variable threshold amounts that are contingent on our credit rating. The variable threshold amounts typically decline for lower credit ratings, while both the variable and fixed threshold amounts typically revert to zero if our credit ratings fall below investment grade. Cash is the primary collateral in all contracts; however, many contracts also permit us to post letters of credit as collateral.

The aggregate fair values of all derivative instruments with such credit-risk-related contingent features that were in a liability position were immaterial at March 31, 2022, and December 31, 2021.

Note 12—Fair Value Measurements

Recurring Fair Value Measurements

We carry certain assets and liabilities at fair value, which we measure at the reporting date using the price that would be received to sell an asset or paid to transfer a liability (i.e., an exit price), and disclose the quality of these fair values based on the valuation inputs used in these measurements under the following hierarchy:

•Level 1: Fair value measured with unadjusted quoted prices from an active market for identical assets or liabilities.

•Level 2: Fair value measured either with: (1) adjusted quoted prices from an active market for similar assets or liabilities; or (2) other valuation inputs that are directly or indirectly observable.

•Level 3: Fair value measured with unobservable inputs that are significant to the measurement.

We classify the fair value of an asset or liability based on the significance of its observable or unobservable inputs to the measurement. However, the fair value of an asset or liability initially reported as Level 3 will be subsequently reported as Level 2 if the unobservable inputs become inconsequential to its measurement or corroborating market data becomes available. Conversely, an asset or liability initially reported as Level 2 will be subsequently reported as Level 3 if corroborating market data becomes unavailable.

We used the following methods and assumptions to estimate the fair value of financial instruments:

•Cash and cash equivalents—The carrying amount reported on our consolidated balance sheet approximates fair value.

•Accounts and notes receivable—The carrying amount reported on our consolidated balance sheet approximates fair value.

•Derivative instruments—We fair value our exchange-traded contracts based on quoted market prices obtained from the New York Mercantile Exchange, the Intercontinental Exchange or other exchanges, and classify them as Level 1 in the fair value hierarchy. When exchange-cleared contracts lack sufficient liquidity, or are valued using either adjusted exchange-provided prices or nonexchange quotes, we classify those contracts as Level 2.

Physical commodity forward purchase and sales contracts and over-the-counter (OTC) financial swaps are generally valued using forward quotes provided by brokers and price index developers, such as Platts and Oil Price Information Service. We corroborate these quotes with market data and classify the resulting fair values as Level 2. When forward market prices are not available, we estimate fair value using the forward price of a similar commodity, adjusted for the difference in quality or location. In certain less liquid markets or for longer-term contracts, forward prices are not as readily available. In these circumstances, physical commodity purchase and sales contracts and OTC swaps are valued using internally developed methodologies that consider historical relationships among various commodities that result in management’s best estimate of fair value. We classify these contracts as Level 3. Physical and OTC commodity options are valued using industry-standard models that consider various assumptions, including quoted forward prices for commodities, time value, volatility factors and contractual prices for the underlying instruments, as well as other relevant economic measures. The degree to which these inputs are observable in the forward markets determines whether the options are classified as Level 2 or 3. We use a midmarket pricing convention (the midpoint between bid and ask prices). When appropriate, valuations are adjusted to reflect credit considerations, generally based on available market evidence.

We determine the fair value of our interest rate swaps based on observable market valuations for interest rate swaps that have notional amounts, terms and pay and reset frequencies similar to ours.

19

•Rabbi trust assets—These deferred compensation investments are measured at fair value using unadjusted quoted prices available from national securities exchanges and are therefore categorized as Level 1 in the fair value hierarchy.

•Investment in NOVONIX—Our investment in NOVONIX is measured at fair value using unadjusted quoted prices available from the Australian Securities Exchange and is therefore categorized as Level 1 in the fair value hierarchy.

•Debt—The carrying amount of our floating-rate debt approximates fair value. The fair value of our fixed-rate debt is estimated based on observable market prices.

The following tables display the fair value hierarchy for our financial assets and liabilities either accounted for or disclosed at fair value on a recurring basis. These values are determined by treating each contract as the fundamental unit of account; therefore, derivative assets and liabilities with the same counterparty are shown on a gross basis in the hierarchy sections of these tables, before the effects of counterparty and collateral netting. The following tables also reflect the effect of netting derivative assets and liabilities with the same counterparty for which we have the legal right of offset and collateral netting.

The carrying values and fair values by hierarchy of our financial assets and liabilities, either carried or disclosed at fair value, including any effects of counterparty and collateral netting, were:

Nonrecurring Fair Value Measurements

Equity Investments

In the first quarter of 2021, Phillips 66 Partners wrote down the book value of its investment in Liberty to estimated fair value using a Level 3 nonrecurring fair value measurement. This nonrecurring measurement was based on the estimated fair value of Phillip 66 Partners’ share of the joint venture’s pipeline assets and net working capital at March 31, 2021. See Note 5—Investments, Loans and Long-Term Receivables, for more information regarding Phillips 66 Partners’ transfer of its ownership in Liberty to its co-venturer in April 2021.

(a)We sold NGL, other petrochemical feedstocks and solvents to Chevron Phillips Chemical Company LLC (CPChem), NGL and certain feedstocks to DCP Midstream, LLC (DCP Midstream), gas oil and hydrogen feedstocks to Excel Paralubes (Excel), and refined petroleum products to several of our equity affiliates in the Marketing and Specialties segment, including OnCue and CF United. We also sold certain feedstocks and intermediate products to WRB and acted as an agent for WRB in supplying crude oil and other feedstocks for a fee. In addition, we charged several of our equity affiliates, including CPChem, for the use of common facilities, such as steam generators, waste and water treaters and warehouse facilities.

Note 17—Income Taxes

Our effective income tax rate for the three months ended March 31, 2022, was 21%, compared with 17% for the corresponding period of 2021. The increase in our effective tax rate for the three months ended March 31, 2022, was primarily attributable to the elimination of the favorable noncontrolling interest impact as a result of the completion of the merger between us and Phillips 66 Partners on March 9, 2022.

Note 18—Phillips 66 Partners LP

On March 9, 2022, we completed the previously announced merger between us and Phillips 66 Partners. The merger resulted in the acquisition of all limited partnership interests in Phillips 66 Partners not already owned by us in exchange for approximately 42 million shares of Phillips 66 common stock issued from treasury stock. Phillips 66 Partners common unitholders received 0.50 shares of Phillips 66 common stock for each outstanding Phillips 66 Partners common unit. Phillips 66 Partners’ perpetual convertible preferred units were converted into common units at a premium to the original issuance price prior to being exchanged for Phillips 66 common stock. Upon closing, Phillips 66 Partners became a wholly owned subsidiary of Phillips 66 and its common units are no longer publicly traded.

The merger was accounted for as an equity transaction and resulted in decreases to “Treasury stock” of $3,380 million, “Noncontrolling interests” of $2,163 million, “Capital in excess of par” of $869 million, “Deferred income taxes” of $355 million, and “Cash and cash equivalents” of $2 million, and an increase to “Other accruals” of $5 million on our consolidated balance sheet.

EXECUTIVE OVERVIEW AND BUSINESS ENVIRONMENT

Phillips 66 is a diversified energy company with midstream, chemicals, refining, and marketing and specialties businesses. At March 31, 2022, we had total assets of $61 billion. Our common stock trades on the New York Stock Exchange under the symbol PSX.

Executive Overview

In the first quarter of 2022, we reported earnings of $582 million and generated cash from operating activities of $1.1 billion. We used available cash to fund capital expenditures and investments of $370 million and pay dividends on our common stock of $404 million. We ended the first quarter of 2022 with $3.3 billion of cash and cash equivalents and approximately $5.7 billion of total committed capacity available under our revolving credit facilities.

Our reported earnings for the first quarter of 2022, compared with the first quarter of 2021, reflect a recovery in global demand for refined petroleum products due to the administration of COVID-19 vaccines and the easing of pandemic restrictions that occurred throughout 2021, as well as recovery from effects of the winter storms that occurred in the first quarter of 2021. The increase in global demand and recent market disruptions resulting from the conflict between Russia and Ukraine resulted in the widening of market crack spreads. Consequently, margins and utilization for our Refining segment, sales volumes for our Marketing and Specialties (M&S) segment, and throughput volumes for our Transportation business have improved. In addition, equity earnings from our Chemicals segment increased due to higher sales volumes. However, as uncertainty remains regarding the impacts on the global economy of the lingering pandemic and the conflict between Russia and Ukraine, we will continue to be disciplined in our allocation of capital and monitor the performance of our portfolio.

In addition, we are progressing a multi-year business transformation focused on enterprise-wide opportunities to improve our cost structure. We are targeting a sustainable cost reduction of at least $700 million per year by the end of the transformation period. We will provide updates as the initiative progresses.

Phillips 66 Partners Merger

On March 9, 2022, we completed the previously announced merger between us and Phillips 66 Partners LP (Phillips 66 Partners). The merger resulted in the acquisition of all limited partnership interests in Phillips 66 Partners not already owned by us. Upon closing, Phillips 66 Partners became a wholly owned subsidiary of Phillips 66 and its common units are no longer publicly traded. See Note 18—Phillips 66 Partners LP, in the Notes to Consolidated Financial Statements, for additional information on the merger transaction.

CEO Transition

On April 12, 2022, Greg C. Garland, Chairman of the Board and Chief Executive Officer of Phillips 66 announced his intention to retire from his position as Chief Executive Officer effective July 1, 2022. Mr. Garland will continue to serve as Executive Chairman of the Board with an expected retirement date from this position in 2024. Mark E. Lashier will become President and Chief Executive Officer effective July 1, 2022.

Business Environment

The Midstream segment includes our Transportation and NGL businesses. Our Transportation business contains fee-based operations not directly exposed to commodity price risk. Our NGL business contains both fee-based operations and operations directly impacted by NGL prices. The Midstream segment also includes our 50% equity investment in DCP Midstream, LLC (DCP Midstream). During the first quarter of 2022, NGL prices increased significantly, compared with the first quarter of 2021, due to strong demand and increased crude oil and natural gas prices.

The Chemicals segment consists of our 50% equity investment in Chevron Phillips Chemical Company LLC (CPChem). The chemicals and plastics industry is mainly a commodity-based industry where the margins for key products are based on supply and demand, as well as cost factors. During the first quarter of 2022, the benchmark high-density polyethylene chain margin decreased, compared with the first quarter of 2021. This decrease was mainly due to higher feedstock cost.

Our Refining segment results are driven by several factors, including market crack spreads, refinery throughput, feedstock costs, product yields, turnaround activity, and other operating costs. The price of U.S. benchmark crude oil, West Texas Intermediate (WTI) at Cushing, Oklahoma, increased to an average of $94.49 per barrel during the first quarter of 2022, compared with an average of $57.84 per barrel in the first quarter of 2021. Market crack spreads are used as indicators of refining margins and measure the difference between market prices for refined petroleum products and crude oil. Worldwide market crack spreads increased to an average of $21.93 per barrel during the first quarter of 2022, compared with an average of $13.23 per barrel in the first quarter of 2021. The increases in crude oil prices and market crack spreads were mainly driven by tight supply due to a significant increase in demand for refined petroleum products as economic activities continue to recover as the COVID-19 pandemic recedes, as well as market disruptions from the conflict between Russia and Ukraine.

Results for our M&S segment depend largely on marketing fuel and lubricant margins, and sales volumes of our refined petroleum and other specialty products. While marketing fuel and lubricant margins are primarily driven by market factors, largely determined by the relationship between supply and demand, marketing fuel margins, in particular, are influenced by trends in spot prices, and where applicable, retail prices for refined petroleum products in the regions and countries where we operate. In general, a downward trend of spot prices has a favorable impact on marketing fuel margins, while an upward trend of spot prices has an unfavorable impact on marketing fuel margins. Demand for refined petroleum products has improved in the first quarter of 2022, compared with the first quarter of 2021, as economic activities continue to recover as the COVID-19 pandemic recedes.

RESULTS OF OPERATIONS

Unless otherwise indicated, discussion of results for the three months ended March 31, 2022, is based on a comparison with the corresponding period of 2021.

Consolidated Results

A summary of income (loss) before income taxes by business segment with a reconciliation to net income (loss) attributable to Phillips 66 follows:

	Millions of Dollars
	Three Months Ended March 31
	2022		2021
Midstream	$	242	76
Chemicals	396		154
Refining	123		(1,040)
Marketing and Specialties	316		290
Corporate and Other	(249)		(251)
Income (loss) before income taxes	828		(771)
Income tax expense (benefit)	171		(132)
Net income (loss)	657		(639)
Less: net income attributable to noncontrolling interests	75		15
Net income (loss) attributable to Phillips 66	$	582	(654)

Our net income attributable to Phillips 66 in the first quarter of 2022 was $582 million, compared with a net loss attributable to Phillips 66 of $654 million in the first quarter of 2021. The improvement was primarily due to:

•Improved realized refining margins.

•Higher equity earnings from CPChem.

•Lower impairments in the Midstream segment.

These improvements were partially offset by an unrealized decrease in the fair value of our investment in NOVONIX Limited (NOVONIX), which we acquired in September 2021, as well as the recognition of income tax expense in the first quarter of 2022, compared with an income tax benefit in the first quarter of 2021.

See the “Segment Results” section for additional information on our segment performance and Note 17—Income Taxes, in the Notes to Consolidated Financial Statements, for additional information on income taxes.

30

Statement of Operations Analysis

Sales and other operating revenues and purchased crude oil and products both increased 67% in the first quarter of 2022. These increases were mainly due to higher prices for refined petroleum products, crude oil and NGL, as well as increased sales volumes.

Equity in earnings of affiliates increased $400 million in the first quarter of 2022. The increase was primarily due to higher equity earnings from CPChem mainly driven by improved margins and higher sales volumes and WRB Refining LP (WRB) resulting from improved realized refining margins and higher refinery production. See Chemicals segment analysis in the “Segment Results” section for additional information on CPChem.

Other income (loss) decreased $158 million in the first quarter of 2022. The decrease was primarily due to an unrealized investment loss of $169 million related to the decrease in NOVONIX’s stock price during the first quarter of 2022. We acquired this investment in September 2021. See Note 5—Investments, Loans and Long-Term Receivables, in the Notes to Consolidated Financial Statements, for additional information regarding our investment in NOVONIX.

Impairments decreased $198 million in the first quarter of 2022 due to a before-tax impairment of $198 million recorded in the first quarter of 2021 related to Phillips 66 Partners’ decision to exit the Liberty Pipeline project. See Note 5—Investments, Loans and Long-Term Receivables, in the Notes to Consolidated Financial Statements, for additional information regarding this impairment.

We had income tax expense of $171 million in the first quarter of 2022, compared with an income tax benefit of $132 million in the first quarter of 2021. See Note 17—Income Taxes, in the Notes to Consolidated Financial Statements, for information regarding our effective income tax rates.

Net income attributable to noncontrolling interests increased $60 million in the first quarter of 2022. The increase was primarily driven by the allocation of a portion of the before-tax impairment recorded in the first quarter of 2021 related to the Liberty Pipeline project to the noncontrolling interest owners of Phillips 66 Partners.

The Midstream segment provides crude oil and refined petroleum product transportation, terminaling and processing services, as well as natural gas and NGL transportation, storage, fractionation, processing and marketing services, mainly in the United States. This segment includes our 50% equity investment in DCP Midstream, which includes the operations of DCP Midstream, LP (DCP Partners), its master limited partnership, and our 16% investment in NOVONIX.

Results from our Midstream segment increased $166 million in the first quarter of 2022.

Results from our Transportation business increased $271 million in the first quarter of 2022. The increase was primarily due to a before-tax impairment of $198 million recorded in the first quarter of 2021 related to Phillips 66 Partners’ decision to exit the Liberty Pipeline project, and higher results from both our equity affiliates and wholly owned assets due to increased volumes.

Results from our NGL and Other business increased $56 million in the first quarter of 2022. This increase was primarily due to improved results from Fracs 1, 2, and 3 at the Sweeny Hub and revenues from the start-up of the C2G pipeline in December 2021. Improved results from the Sweeny Fracs reflect recovery from the impacts of the winter storms that occurred in February 2021, which caused lower run rates and higher operating expenses in the first quarter of 2021.

Results from our investment in DCP Midstream decreased $3 million in the first quarter of 2022.

32

The fair value of our investment in NOVONIX decreased by $158 million in the first quarter of 2022. We acquired this investment in September 2021.

See Note 5—Investments, Loans and Long-Term Receivables, in the Notes to Consolidated Financial Statements, for additional information regarding the Liberty Pipeline project impairment and our investment in NOVONIX.

Olefins and Polyolefins Capacity Utilization (percent) 99  % 79 

The Chemicals segment consists of our 50% interest in CPChem, which we account for under the equity method. CPChem uses NGL and other feedstocks to produce petrochemicals. These products are then marketed and sold or used as feedstocks to produce plastics and other chemicals. We structure our reporting of CPChem’s operations around two primary business lines: Olefins and Polyolefins (O&P) and Specialties, Aromatics and Styrenics (SA&S).

Results from the Chemicals segment increased $242 million in the first quarter of 2022. The increase was primarily due to improved O&P margins reflecting strong demand and higher sales volumes. Results in the first quarter of 2021 were negatively impacted by the winter storms that occurred in the Central and Gulf Coast regions.

The Refining segment refines crude oil and other feedstocks into petroleum products, such as gasoline, distillates and aviation fuels, at 12 refineries in the United States and Europe. In the fourth quarter of 2021, we shut down our Alliance Refinery and are in the process of converting it into a terminal.

Results from our Refining segment increased $1,163 million in the first quarter of 2022, primarily due to higher realized refining margins. The improved realized refining margins were mainly attributable to increased market crack spreads, partially offset by decreased secondary product margins and lower clean product differentials.

Our worldwide refining crude oil capacity utilization rate was 89% in the first quarter of 2022, compared with 74% in the first quarter of 2021. The increase was primarily driven by improved market demand for refined petroleum products following the administration of COVID-19 vaccines and the easing of pandemic restrictions, as well as less unplanned downtime caused by the winter storms that occurred in February 2021.

The M&S segment purchases for resale and markets refined petroleum products, such as gasoline, distillates and aviation fuels, mainly in the United States and Europe. In addition, this segment includes the manufacturing and marketing of specialty products, such as base oils and lubricants.

Before-tax income from the M&S segment increased $26 million in the first quarter of 2022, primarily driven by higher results from our lubricants business reflecting increased finished lubricant and Excel Paralubes base oil margins, higher marketing sales volumes and improved results from our chartered marine vessel and other businesses. These increases were partially offset by lower marketing fuel margins primarily due to spot prices increasing more significantly in the first quarter of 2022, compared with the first quarter of 2021.

Net interest expense consists of interest and financing expense, net of interest income and capitalized interest. Corporate overhead and other includes general and administrative expenses, technology costs, environmental costs associated with sites no longer in operation, foreign currency transaction gains and losses, and other costs not directly associated with an operating segment.

Net interest expense decreased $11 million in the first quarter of 2022, primarily driven by lower average debt principal balances, reflecting debt repayments during 2021, as well as higher capitalized interest primarily due to the restart of the Sweeny Frac 4 capital project.

Corporate overhead and other increased $9 million in the first quarter of 2022, reflecting higher employee-related expenses.

* Capital includes total debt and total equity.

To meet our short- and long-term liquidity requirements, we use a variety of funding sources but rely primarily on cash generated from operating activities and debt financing. During the first three months of 2022, we generated $1.1 billion of cash from operations. We used available cash primarily for capital expenditures and investments of $370 million and dividend payments on our common stock of $404 million. During the first three months of 2022, cash and cash equivalents increased $188 million to $3.3 billion.

Significant Sources of Capital

Operating Activities

During the first three months of 2022, cash generated by operating activities was $1.1 billion, compared with $271 million for the first three months of 2021. The increase was primarily due to improved realized refining margins, partially offset by unfavorable working capital impacts.

Our short- and long-term operating cash flows are highly dependent upon refining and marketing margins, NGL prices and chemicals margins. Prices and margins in our industry are typically volatile, and are driven by market conditions over which we have little or no control. Absent other mitigating factors, as these prices and margins fluctuate, we would expect a corresponding change in our operating cash flows.

The level and quality of output from our refineries also impact our cash flows. Factors such as operating efficiency, maintenance turnarounds, market conditions, feedstock availability, and weather conditions can affect output. We actively manage the operations of our refineries, and any variability in their operations typically has not been as significant to cash flows as that caused by margins and prices.

Equity Affiliate Operating Distributions

Our operating cash flows are also impacted by distribution decisions made by our equity affiliates, including CPChem. During the first three months of 2022, cash from operations included aggregate distributions of $585 million from our equity affiliates, including $299 million from CPChem. During the same period of 2021, cash from operations included aggregate distributions of $502 million, including $205 million from CPChem. We cannot control the amount of future dividends from equity affiliates; therefore, future dividend payments by these equity affiliates are not assured.

Revolving Credit Facilities and Commercial Paper

At both March 31, 2022, and December 31, 2021, no amount had been drawn under Phillips 66’s $5 billion revolving credit facility or uncommitted $5 billion commercial paper program. At March 31, 2022 and December 31, 2021, no borrowings were outstanding and $1 million in letters of credit had been drawn under Phillips 66 Partners’ $750 million revolving credit facility.

39

Off-Balance Sheet Arrangements

Lease Residual Value Guarantees

Under the operating lease agreement for our headquarters facility in Houston, Texas, we have the option, at the end of the lease term in September 2025, to request to renew the lease, purchase the facility or assist the lessor in marketing it for resale. We have a residual value guarantee associated with the operating lease agreement with a maximum potential future exposure of $514 million at March 31, 2022. We also have residual value guarantees associated with railcar and airplane leases with maximum potential future exposures totaling $221 million. These leases have remaining terms of up to ten years.

Dakota Access, LLC (Dakota Access) and Energy Transfer Crude Oil Company, LLC (ETCO)

In 2020, the trial court presiding over litigation brought by the Standing Rock Sioux Tribe ordered the U.S. Army Corps of Engineers (USACE) to prepare an Environmental Impact Statement (EIS) addressing an easement under Lake Oahe in North Dakota. The court later vacated the easement. Although the easement is vacated, the USACE has indicated that it will not take action to stop pipeline operations while it proceeds with the EIS. In May 2021, the Standing Rock Sioux Tribe’s request for an injunction to force a shutdown of the pipeline while the EIS is being prepared was denied. In June 2021, the trial court dismissed the litigation entirely. Once the EIS is completed, new litigation or challenges to the EIS could be filed.

In September 2021, Dakota Access filed a writ of certiorari, requesting the U.S. Supreme Court to review the lower court’s decision to order the EIS and vacate the easement. In February 2022, the writ was denied, and the requirement to prepare the EIS stands. Completion of the EIS was expected in the fall of 2022, but now may be delayed as the USACE engages with the Standing Rock Sioux Tribe on their reasons for withdrawing as a cooperating agency with respect to preparation of the EIS.

Dakota Access and ETCO have guaranteed repayment of senior unsecured notes issued by a wholly owned subsidiary of Dakota Access with an aggregate principal outstanding of $2.5 billion at March 31, 2022. In addition, Phillips 66 Partners, now a wholly owned subsidiary of Phillips 66, and its co-venturers in Dakota Access provided a Contingent Equity Contribution Undertaking (CECU) in conjunction with the notes offering. Under the CECU, the co-venturers may be severally required to make proportionate equity contributions to Dakota Access if there is an unfavorable final judgment in the above-mentioned ongoing litigation. At March 31, 2022, our share of the maximum potential equity contributions under the CECU was approximately $631 million.

If the pipeline is required to cease operations, and should Dakota Access and ETCO not have sufficient funds to pay ongoing expenses, we could be required to support our share of the ongoing expenses, including scheduled interest payments on the notes of approximately $25 million annually, in addition to the potential obligations under the CECU at March 31, 2022.

On April 1, 2022, Dakota Access’ wholly owned subsidiary repaid $650 million aggregate principal amount of its outstanding senior notes upon maturity. We funded our 25% share, or $163 million, with a capital contribution of $89 million in March 2022 and $74 million of distributions we elected not to receive from Dakota Access in the first quarter of 2022. As a result of the debt repayment, on April 1, 2022, our share of the maximum potential equity contributions under the CECU decreased to approximately $467 million, and our share of scheduled interest payments on the notes that we could be required to support decreased to approximately $20 million annually.

See Note 9—Guarantees, in the Notes to Consolidated Financial Statements, for additional information on our guarantees.

Capital Requirements

Capital Expenditures and Investments

For information about our capital expenditures and investments, see the “Capital Spending” section below.

Debt Financing

Our total debt balance at both March 31, 2022, and December 31, 2021, was $14.4 billion. Our total debt-to-capital ratio was 39% and 40% at March 31, 2022, and December 31, 2021, respectively.

In early April 2022, upon maturity, Phillips 66 repaid its 4.300% senior notes with an aggregate principal amount of $1.0 billion and Phillips 66 Partners repaid its $450 million term loan. As our operating cash flows improve further, we will continue to prioritize debt reductions in 2022.

Debt Exchange

On April 6, 2022, Phillips 66 Company, a wholly owned subsidiary of Phillips 66, announced offers to exchange (the Exchange Offers) all validly tendered notes of seven different series of notes issued by Phillips 66 Partners (collectively, the Old Notes), with an aggregate principal amount of approximately $3.5 billion, for notes to be issued by Phillips 66 Company (collectively, the New Notes). The New Notes will be fully and unconditionally guaranteed by Phillips 66 and will rank equally with Phillips 66 Company’s other unsecured and unsubordinated indebtedness, and the guarantees will rank equally with Phillips 66’s other unsecured and unsubordinated indebtedness. The Exchange Offers will expire on May 3, 2022, unless such date is extended (the Expiration Date). Phillips 66 Company currently expects the settlement of the Exchange Offers to occur on May 5, 2022, unless the Expiration Date is extended.

The New Notes will have the same interest rates, interest payment dates and maturity dates as the Old Notes. In addition, holders that validly tender before the end of the early participation period on April 19, 2022 (the Early Participation Date), will receive New Notes with an aggregate principal amount equivalent to the Old Notes, while holders that validly tender after the Early Participation Date, but before the Expiration Date, will receive New Notes with an aggregate principal amount that is 3% less than the Old Notes.

Through the end of the early participation period on April 19, 2022, Old Notes with an aggregate principal amount of approximately $3.2 billion had been validly tendered for exchange.

Joint Venture Loans

We and our co-venturer provided member loans to WRB. At March 31, 2022, our 50% share of the outstanding member loan balance, including accrued interest, was $597 million. The need for additional loans to WRB in the remainder of 2022, as well as WRB’s repayment schedule, will depend on market conditions.

Merger with Phillips 66 Partners

On March 9, 2022, we completed the previously announced merger between us and Phillips 66 Partners. The merger resulted in the acquisition of all limited partnership interests in Phillips 66 Partners not already owned by us in exchange for approximately 42 million shares of Phillips 66 common stock issued from treasury stock. Phillips 66 Partners common unitholders received 0.50 shares of Phillips 66 common stock for each outstanding Phillips 66 Partners common unit. Phillips 66 Partners’ perpetual convertible preferred units were converted into common units at a premium to the original issuance price prior to being exchanged for Phillips 66 common stock. Upon closing, Phillips 66 Partners became a wholly owned subsidiary of Phillips 66 and its common units are no longer publicly traded. See Note 18—Phillips 66 Partners LP, in the Notes to Consolidated Financial Statements, for additional information on the merger transaction.

Dividends

On February 9, 2022, our board of directors declared a quarterly cash dividend of $0.92 per common share. This dividend was paid on March 1, 2022, to shareholders of record as of the close of business on February 22, 2022.

41

Share Repurchases

Since July 2012, our board of directors has authorized an aggregate of $15 billion of repurchases of our outstanding common stock. The authorizations do not have expiration dates. Future share repurchases are expected to be funded primarily through available cash. We are not obligated to repurchase any shares of common stock pursuant to these authorizations and may commence, suspend or terminate repurchases at any time. Since the inception of our share repurchase program in 2012, we have repurchased 159 million shares at an aggregate cost of $12.5 billion. Shares of stock repurchased are held as treasury shares. We suspended share repurchases in mid-March 2020 to preserve liquidity in response to the global economic disruption caused by the COVID-19 pandemic. In April 2022, we announced plans to resume our share repurchase program in the second quarter of 2022.

* Our share of joint venture’s capital spending.

Midstream

During the first three months of 2022, capital spending in our Midstream segment included:

•Contribution to Dakota Access to fund our 25% share of Dakota Access’ debt repayment in April 2022.

•Continued development of additional Gulf Coast fractionation capacity at our Sweeny Hub.

•Spending associated with other return, reliability, and maintenance projects in our Transportation and NGL businesses.

Chemicals

During the first three months of 2022, on a 100% basis, CPChem’s capital expenditures and investments were $225 million. The capital spending was primarily for the development of petrochemical projects on the U.S. Gulf Coast and in the Middle East, as well as sustaining, debottlenecking and optimization projects on existing assets. CPChem’s capital program was self-funded, and we expect CPChem to continue self-funding its capital program for the remainder of 2022.

Refining

Capital spending for the Refining segment during the first three months of 2022 was primarily for refinery upgrade projects to enhance the yield of high-value products, renewable diesel projects, improvements to the operating integrity of key processing units, and safety-related projects.

Major capital activities included:

•Installation of facilities to improve product value at the Lake Charles refinery.

•Engineering of facilities to produce biofuels at the San Francisco refinery.

43

Marketing and Specialties

Capital spending for the M&S segment during the first three months of 2022 was primarily for the continued development and enhancement of retail sites in Europe and for Lubricants reliability and maintenance projects.

Corporate and Other

Capital spending for Corporate and Other during the first three months of 2022 was primarily for information technology and facilities.

44

Contingencies

A number of lawsuits involving a variety of claims that arose in the ordinary course of business have been filed against us or are subject to indemnifications provided by us. We also may be required to remove or mitigate the effects on the environment of the placement, storage, disposal, or release of certain chemical, mineral and petroleum substances at various active and inactive sites. We regularly assess the need for financial recognition or disclosure of these contingencies. In the case of all known contingencies (other than those related to income taxes), we accrue a liability when the loss is probable and the amount is reasonably estimable. If a range of amounts can be reasonably estimated and no amount within the range is a better estimate than any other amount, then the minimum of the range is accrued. We do not reduce these liabilities for potential insurance or third-party recoveries. If applicable, we accrue receivables for probable insurance or other third-party recoveries. In the case of income tax-related contingencies, we use a cumulative probability-weighted loss accrual in cases where sustaining a tax position is uncertain.

Based on currently available information, we believe it is remote that future costs related to known contingent liability exposures will exceed current accruals by an amount that would have a material adverse impact on our consolidated financial statements. As we learn new facts concerning contingencies, we reassess our position both with respect to accrued liabilities and other potential exposures. Estimates particularly sensitive to future changes include contingent liabilities recorded for environmental remediation, tax and legal matters. Estimated future environmental remediation costs are subject to change due to such factors as the uncertain magnitude of cleanup costs, the unknown time and extent of such remedial actions that may be required, and the determination of our liability in proportion to that of other potentially responsible parties. Estimated future costs related to tax and legal matters are subject to change as events evolve and as additional information becomes available during the administrative and litigation processes.

Legal and Tax Matters

Our legal and tax matters are handled by our legal and tax organizations. These organizations apply their knowledge, experience and professional judgment to the specific characteristics of our cases and uncertain tax positions. We employ a litigation management process to manage and monitor the legal proceedings. Our process facilitates the early evaluation and quantification of potential exposures in individual cases and enables the tracking of those cases that have been scheduled for trial and/or mediation. Based on professional judgment and experience in using these litigation management tools and available information about current developments in all our cases, our legal organization regularly assesses the adequacy of current accruals and determines if adjustment of existing accruals, or establishment of new accruals, is required. In the case of income tax-related contingencies, we monitor tax legislation and court decisions, the status of tax audits and the statute of limitations within which a taxing authority can assert a liability.

45

Environmental

Like other companies in our industry, we are subject to numerous international, federal, state and local environmental laws and regulations. For a discussion of the most significant international and federal environmental laws and regulations to which we are subject, see the “Environmental” section in Management’s Discussion and Analysis of Financial Condition and Results of Operations in our 2021 Annual Report on Form 10-K.

We are required to purchase RINs in the open market to satisfy the portion of our obligation under the Renewable Fuel Standard (RFS) that is not fulfilled by blending renewable fuels into the motor fuels we produce. For the three months ended March 31, 2022 and 2021, we incurred expenses of $152 million and $165 million, respectively, associated with our obligation to purchase RINs in the open market to comply with the RFS for our wholly owned refineries. These expenses are included in the “Purchased crude oil and products” line item on our consolidated statement of operations. Our jointly owned refineries also incurred expenses associated with the purchase of RINs in the open market, of which our share was $85 million and $63 million for the three months ended March 31, 2022 and 2021, respectively. These expenses are included in the “Equity in earnings of affiliates” line item on our consolidated statement of operations. The amount of these expenses and fluctuations between periods is primarily driven by the market price of RINs, refinery production, blending activities and renewable volume obligation requirements.

We occasionally receive requests for information or notices of potential liability from the EPA and state environmental agencies alleging that we are a potentially responsible party under the Federal Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) or an equivalent state statute. On occasion, we also have been made a party to cost recovery litigation by those agencies or by private parties. These requests, notices and lawsuits assert potential liability for remediation costs at various sites that typically are not owned by us, but allegedly contain wastes attributable to our past operations. At December 31, 2021, we reported that we had been notified of potential liability under CERCLA and comparable state laws at 25 sites within the United States. In the first quarter of 2022, we were notified of one site that was deemed resolved and closed, accordingly, leaving 24 unresolved sites with potential liability at March 31, 2022.

Notwithstanding any of the foregoing, and as with other companies engaged in similar businesses, environmental costs and liabilities are inherent concerns in certain of our operations and products, and there can be no assurance that those costs and liabilities will not be material. However, we currently do not expect any material adverse effect on our results of operations or financial position as a result of compliance with current environmental laws and regulations.

46

Climate Change

There has been a broad range of proposed or promulgated state, national and international laws focusing on GHG emissions reduction, including various regulations proposed or issued by the EPA. These proposed or promulgated laws apply or could apply in states and/or countries where we have interests or may have interests in the future. Laws regulating GHG emissions continue to evolve, and while it is not possible to accurately estimate either a timetable for implementation or our future compliance costs relating to implementation, such laws potentially could have a material impact on our results of operations and financial condition as a result of increasing costs of compliance, lengthening project implementation and agency reviews, or reducing demand for certain hydrocarbon products. We continue to monitor legislative and regulatory actions and legal proceedings globally relating to GHG emissions for potential impacts on our operations.

For examples of legislation and regulation or precursors for possible regulation that do or could affect our operations, see the “Climate Change” section in Management’s Discussion and Analysis of Financial Condition and Results of Operations in our 2021 Annual Report on Form 10-K.

We consider and take into account anticipated future GHG emissions in designing and developing major facilities and projects, and implement energy efficiency initiatives to reduce GHG emissions. Data on our GHG emissions, legal requirements regulating such emissions, and the possible physical effects of climate change on our coastal assets are incorporated into our planning, investment, and risk management decision-making. We are working to continuously improve operational and energy efficiency through resource and energy conservation throughout our operations.

In February 2022, we announced our intention by 2050 to reduce the GHG emissions intensity for Scope 1 and Scope 2 emissions from our operations by 50% compared to 2019 levels. This new target builds upon our previously announced 2030 GHG emissions intensity targets to reduce Scope 1 and Scope 2 emissions from our operations by 30% and Scope 3 emissions from our energy products by 15% compared to 2019 levels.

GUARANTOR FINANCIAL INFORMATION

At March 31, 2022, Phillips 66 had $10.3 billion of senior unsecured notes outstanding guaranteed by Phillips 66 Company, a direct, wholly owned operating subsidiary of Phillips 66. Phillips 66 conducts substantially all of its operations through subsidiaries, including Phillips 66 Company, and those subsidiaries generate substantially all of its operating income and cash flow. The guarantees (1) are unsecured obligations of Phillips 66 Company, (2) rank equally with all of Phillips 66 Company’s other unsecured and unsubordinated indebtedness, and (3) are full and unconditional.

See the “Significant Sources of Capital” section for additional information regarding the Exchange Offers by Phillips 66 Company for existing senior notes of Phillips 66 Partners that are expected to be settled in May 2022.

Summarized financial information of Phillips 66 and Phillips 66 Company (the Obligor Group) is presented on a combined basis. Intercompany transactions among the members of the Obligor Group have been eliminated. The financial information of non-guarantor subsidiaries has been excluded from the summarized financial information. Significant intercompany transactions and receivable/payable balances between the Obligor Group and non-guarantor subsidiaries are presented separately in the summarized financial information.

NON-GAAP RECONCILIATIONS

Refining

Our realized refining margins measure the difference between (a) sales and other operating revenues derived from the sale of petroleum products manufactured at our refineries and (b) costs of feedstocks, primarily crude oil, used to produce the petroleum products. The realized refining margins are adjusted to include our proportional share of our joint venture refineries’ realized margins, as well as to exclude those items that are not representative of the underlying operating performance of a period, which we call “special items.” The realized refining margins are converted to a per-barrel basis by dividing them by total refinery processed inputs (primarily crude oil) measured on a barrel basis, including our share of inputs processed by our joint venture refineries. Our realized refining margin per barrel is intended to be comparable with industry refining margins, which are known as “crack spreads.” As discussed in “Executive Overview and Business Environment—Business Environment,” industry crack spreads measure the difference between market prices for refined petroleum products and crude oil. We believe realized refining margin per barrel calculated on a similar basis as industry crack spreads provides a useful measure of how well we performed relative to benchmark industry refining margins.

The GAAP performance measure most directly comparable to realized refining margin per barrel is the Refining segment’s “income (loss) before income taxes per barrel.” Realized refining margin per barrel excludes items that are typically included in a manufacturer’s gross margin, such as depreciation and operating expenses, and other items used to determine income (loss) before income taxes, such as general and administrative expenses. It also includes our proportional share of joint venture refineries’ realized refining margins and excludes special items. Because realized refining margin per barrel is calculated in this manner, and because realized refining margin per barrel may be defined differently by other companies in our industry, it has limitations as an analytical tool. Following are reconciliations of income (loss) before income taxes to realized refining margins:

Marketing

Our realized marketing fuel margins measure the difference between (a) sales and other operating revenues derived from the sale of fuels in our M&S segment and (b) costs of those fuels. The realized marketing fuel margins are adjusted to exclude those items that are not representative of the underlying operating performance of a period, which we call “special items.” The realized marketing fuel margins are converted to a per-barrel basis by dividing them by sales volumes measured on a barrel basis. We believe realized marketing fuel margin per barrel demonstrates the value uplift our marketing operations provide by optimizing the placement and ultimate sale of our refineries’ fuel production.

Within the M&S segment, the GAAP performance measure most directly comparable to realized marketing fuel margin per barrel is the marketing business’ “income before income taxes per barrel.” Realized marketing fuel margin per barrel excludes items that are typically included in gross margin, such as depreciation and operating expenses, and other items used to determine income before income taxes, such as general and administrative expenses. Because realized marketing fuel margin per barrel excludes these items, and because realized marketing fuel margin per barrel may be defined differently by other companies in our industry, it has limitations as an analytical tool. Following are reconciliations of income before income taxes to realized marketing fuel margins:

CAUTIONARY STATEMENT FOR THE PURPOSES OF THE “SAFE HARBOR” PROVISIONS OF THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995

This report includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. You can normally identify our forward-looking statements by the words “anticipate,” “estimate,” “believe,” “budget,” “continue,” “could,” “intend,” “may,” “plan,” “potential,” “predict,” “seek,” “should,” “will,” “would,” “expect,” “objective,” “projection,” “forecast,” “goal,” “guidance,” “outlook,” “effort,” “target” and similar expressions, but the absence of such words does not mean a statement is not forward-looking.

We based the forward-looking statements on our current expectations, estimates and projections about us, our operations, our joint ventures and entities in which we have equity interests, as well as the industries in which we and they operate in general. We caution you these statements are not guarantees of future performance as they involve assumptions that, while made in good faith, may prove to be incorrect, and involve risks and uncertainties we cannot predict. In addition, we based many of these forward-looking statements on assumptions about future events that may prove to be inaccurate. Accordingly, our actual outcomes and results may differ materially from what we have expressed or forecast in the forward-looking statements. Any differences could result from a variety of factors, including the following:

•The negative impact on commercial activity and demand for refined petroleum products from any widespread public health crisis, as well as the extent and duration of recovery of economies and demand for our products following any such crisis.

•Fluctuations in NGL, crude oil, refined petroleum product and natural gas prices and refining, marketing and petrochemical margins.

•Changes in governmental policies relating to NGL, crude oil, natural gas or refined petroleum products pricing, regulation or taxation, including exports.

•Actions taken by OPEC and other countries impacting supply and demand and correspondingly, commodity prices.

•Unexpected changes in costs or technical requirements for constructing, modifying or operating our facilities or transporting our products.

•Unexpected technological or commercial difficulties in manufacturing, refining or transporting our products, including chemical products.

•Lack of, or disruptions in, adequate and reliable transportation for our NGL, crude oil, natural gas and refined petroleum products.

•The level and success of drilling and quality of production volumes around our Midstream assets.

•The inability to timely obtain or maintain permits, including those necessary for capital projects.

•The inability to comply with government regulations or make capital expenditures required to maintain compliance.

•Changes to worldwide government policies relating to renewable fuels and greenhouse gas emissions that adversely affect programs like the renewable fuel standards program, low carbon fuel standards and tax credits for biofuels.

•Failure to complete definitive agreements and feasibility studies for, and to complete construction of, announced and future capital projects on time and within budget.

•Potential disruption or interruption of our operations due to accidents, weather events, civil unrest, insurrections, political events, terrorism or cyberattacks.

•Potential disruption or damage to our facilities as a result of significant storms, flooding or other destructive climate events.

•The inability to meet our sustainability goals, including reducing our GHG emissions intensity, developing and protecting new technologies, and commercializing lower-carbon opportunities.

53

•General domestic and international economic and political developments including armed hostilities, expropriation of assets, and other political, economic or diplomatic developments, including those caused by public health issues, outbreaks of diseases and pandemics.

•Failure of new products and services to achieve market acceptance.

•International monetary conditions and exchange controls.

Item 3.   QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our commodity price risk and interest rate risk at March 31, 2022, did not differ materially from the risks disclosed under Item 7A of our 2021 Annual Report on Form 10-K.

Item 4.   CONTROLS AND PROCEDURES

We maintain disclosure controls and procedures designed to ensure that information required to be disclosed in reports we file or submit under the Securities Exchange Act of 1934, as amended (the Act), is recorded, processed, summarized and reported within the time periods specified in U.S. Securities and Exchange Commission (SEC) rules and forms, and that such information is accumulated and communicated to management, including our principal executive and principal financial officers, as appropriate, to allow timely decisions regarding required disclosure. As of March 31, 2022, with the participation of management, our Chairman and Chief Executive Officer and our Executive Vice President, Finance and Chief Financial Officer carried out an evaluation, pursuant to Rule 13a-15(b) of the Act, of the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) of the Act). Based upon that evaluation, our Chairman and Chief Executive Officer and our Executive Vice President, Finance and Chief Financial Officer concluded that our disclosure controls and procedures were operating effectively as of March 31, 2022.

There have been no changes in our internal control over financial reporting, as defined in Rule 13a-15(f) of the Act, in the quarterly period ended March 31, 2022, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

55

PART II. OTHER INFORMATION

Item 1.   LEGAL PROCEEDINGS

From time to time, we may be involved in litigation and claims arising out of our operations in the normal course of business. Additionally, Item 103 of Regulation S-K promulgated by the SEC requires disclosure of certain environmental matters when a governmental authority is a party to the proceedings and such proceedings involve potential monetary sanctions that we reasonably believe will be in excess of $300,000. During the first quarter of 2022, there were no such new matters that arose and there were no material developments that occurred with respect to matters previously reported but still unresolved. We do not currently believe that the eventual outcome of any matters previously reported but still unresolved, individually or in the aggregate, could have a material adverse effect on our business, financial condition, results of operations or cash flows.

Our U.S. refineries are implementing two separate consent decrees, regarding alleged violations of the Federal Clean Air Act, with the EPA, five states and one local air pollution agency. Some of the requirements and limitations contained in the decrees provide for stipulated penalties for violations. Stipulated penalties under the decrees are not automatic, but must be requested by one of the agency signatories. As part of periodic reports under the decrees or other reports required by permits or regulations, we occasionally report matters that could be subject to a request for stipulated penalties. If a specific request for stipulated penalties meeting the reporting threshold set forth in SEC rules is made pursuant to these decrees based on a given reported exceedance, we will separately report that matter and the amount of the proposed penalty.

See Note 10—Contingencies and Commitments, in the Notes to Consolidated Financial Statements, for additional information.

Item 1A.   RISK FACTORS

There were no material changes from the risk factors disclosed in Item 1A of our 2021 Annual Report on Form 10-K.

Item 2.   UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

Issuer Purchases of Equity Securities

In March 2020, we announced that we had temporarily suspended our share repurchases. As of March 31, 2022, we had $2,514 million remaining on our existing share repurchase authorization, which has no expiration date. In April 2022, we announced plans to resume our share repurchase program in the second quarter of 2022. Any future share repurchases will be made at the discretion of management and will depend on various factors including our share price, results of operations, financial condition and cash required for future business plans.

At March 31, 2022, and December 31, 2021, receivables from contracts with customers were $8,604 million and $6,140 million, respectively. Significant noncustomer balances, such as buy/sell receivables and excise tax receivables, were excluded from these amounts.

Our contract-related assets also include payments we make to our marketing customers related to incentive programs. An incentive payment is initially recognized as an asset and subsequently amortized as a reduction to revenue over the contract term, which generally ranges from 5 to 15 years. At March 31, 2022, and December 31, 2021, our asset balances related to such payments were $471 million and $466 million, respectively.

Our contract liabilities represent advances from our customers prior to product or service delivery. At March 31, 2022, and December 31, 2021, contract liabilities were not material.

Remaining Performance Obligations

Most of our contracts with customers are spot contracts or term contracts with only variable consideration. We do not disclose remaining performance obligations for these contracts as the expected duration is one year or less or because the variable consideration has been allocated entirely to an unsatisfied performance obligation. We also have certain contracts in our Midstream segment that include minimum volume commitments with fixed pricing. At March 31, 2022, the remaining performance obligations related to these minimum volume commitment contracts were immaterial.

Credit Loss [Abstract]

Credit Losses

Credit Losses

We are exposed to credit losses primarily through our sales of refined petroleum products, crude oil and NGL. We assess each counterparty’s ability to pay for the products we sell by conducting a credit review. The credit review considers our expected billing exposure and timing for payment and the counterparty’s established credit rating or our assessment of the counterparty’s creditworthiness based on our analysis of their financial statements when a credit rating is not available. We also consider contract terms and conditions, country and political risk, and business strategy in our evaluation. A credit limit is established for each counterparty based on the outcome of this review. We may require collateralized asset support or a prepayment to mitigate credit risk.

We monitor our ongoing credit exposure through active review of counterparty balances against contract terms and due dates. Our activities include timely account reconciliations, dispute resolution and payment confirmations. We may employ collection agencies and legal counsel to pursue recovery of defaulted receivables. In addition, when events and circumstances arise that may affect certain counterparties’ abilities to fulfill their obligations, such as Coronavirus Disease 2019 (COVID-19), we enhance our credit monitoring, and we may seek collateral to support some transactions or require prepayments from higher-risk counterparties.

At March 31, 2022, and December 31, 2021, we reported $10,455 million and $7,470 million of accounts and notes receivable, respectively, net of allowances of $44 million for both periods. Based on an aging analysis at March 31, 2022, more than 95% of our accounts receivable were outstanding less than 60 days.

We are also exposed to credit losses from off-balance sheet exposures, such as guarantees of joint venture debt and standby letters of credit. See Note 9—Guarantees, and Note 10—Contingencies and Commitments, for more information on these off-balance sheet exposures.

Dakota Access, LLC (Dakota Access) and Energy Transfer Crude Oil Company, LLC (ETCO)

In 2020, the trial court presiding over litigation brought by the Standing Rock Sioux Tribe ordered the U.S. Army Corps of Engineers (USACE) to prepare an Environmental Impact Statement (EIS) addressing an easement under Lake Oahe in North Dakota. The court later vacated the easement. Although the easement is vacated, the USACE has indicated that it will not take action to stop pipeline operations while it proceeds with the EIS. In May 2021, the Standing Rock Sioux Tribe’s request for an injunction to force a shutdown of the pipeline while the EIS is being prepared was denied. In June 2021, the trial court dismissed the litigation entirely. Once the EIS is completed, new litigation or challenges to the EIS could be filed.

In September 2021, Dakota Access filed a writ of certiorari, requesting the U.S. Supreme Court to review the lower court’s decision to order the EIS and vacate the easement. In February 2022, the writ was denied, and the requirement to prepare the EIS stands. Completion of the EIS was expected in the fall of 2022, but now may be delayed as the USACE engages with the Standing Rock Sioux Tribe on their reasons for withdrawing as a cooperating agency with respect to preparation of the EIS.

Dakota Access and ETCO have guaranteed repayment of senior unsecured notes issued by a wholly owned subsidiary of Dakota Access with an aggregate principal outstanding of $2.5 billion at March 31, 2022. In addition, Phillips 66 Partners, now a wholly owned subsidiary of Phillips 66, and its co-venturers in Dakota Access provided a Contingent Equity Contribution Undertaking (CECU) in conjunction with the notes offering. Under the CECU, the co-venturers may be severally required to make proportionate equity contributions to Dakota Access if there is an unfavorable final judgment in the above-mentioned ongoing litigation. At March 31, 2022, our share of the maximum potential equity contributions under the CECU was approximately $631 million.

If the pipeline is required to cease operations, and should Dakota Access and ETCO not have sufficient funds to pay ongoing expenses, we could be required to support our share of the ongoing expenses, including scheduled interest payments on the notes of approximately $25 million annually, in addition to the potential obligations under the CECU at March 31, 2022.

At March 31, 2022, the aggregate book value of our investments in Dakota Access and ETCO was $725 million.

On April 1, 2022, Dakota Access’ wholly owned subsidiary repaid $650 million aggregate principal amount of its outstanding senior notes upon maturity. We funded our 25% share, or $163 million, with a capital contribution of $89 million in March 2022 and $74 million of distributions we elected not to receive from Dakota Access in the first quarter of 2022. As a result of the debt repayment, on April 1, 2022, our share of the maximum potential equity contributions under the CECU decreased to approximately $467 million, and our share of scheduled interest payments on the notes that we could be required to support decreased to approximately $20 million annually.

CF United LLC (CF United)

We hold a 50% voting interest and a 48% economic interest in CF United, a retail marketing joint venture with operations primarily on the U.S. West Coast. CF United is considered a variable interest entity (VIE) because our co-venturer has an option to require us to purchase its interest based on a fixed multiple. The put option becomes effective July 1, 2023, and expires on March 31, 2024. The put option is viewed as a variable interest as the purchase price on the exercise date may not represent the then-current fair value of CF United. We have determined that we are not the primary beneficiary because we and our co-venturer jointly direct the activities of CF United that most significantly impact economic performance. At March 31, 2022, our maximum exposure to loss was comprised of our $278 million investment in CF United, and any potential future loss resulting from the put option should the purchase price based on a fixed multiple exceed the then-current fair value of CF United.

OnCue Holdings, LLC (OnCue)

We hold a 50% interest in OnCue, a joint venture that owns and operates retail convenience stores. We fully guaranteed various debt agreements of OnCue and our co-venturer did not participate in the guarantees. This entity is considered a VIE because our debt guarantees resulted in OnCue not being exposed to all potential losses. We have determined we are not the primary beneficiary because we do not have the power to direct the activities that most significantly impact economic performance. At March 31, 2022, our maximum exposure to loss was $188 million, which represented the book value of our investment in OnCue of $120 million and guaranteed debt obligations of $68 million.

Liberty Pipeline LLC (Liberty)

In the first quarter of 2021, Phillips 66 Partners decided to exit the Liberty Pipeline project, which resulted in a $198 million before-tax impairment in our Midstream segment. The impairment is included in the “Impairments” line item on our consolidated statement of operations for the three months ended March 31, 2021. See Note 12—Fair Value Measurements, for additional information regarding this impairment and the techniques used to determine the fair value of this investment. In April 2021, Phillips 66 Partners transferred its ownership interest in Liberty to its co-venturer for cash and certain pipeline assets with a value that approximated its book value of $46 million at March 31, 2021.

Other Investments

In September 2021, we acquired 78 million ordinary shares, representing a 16% ownership interest, in NOVONIX Limited (NOVONIX), which are traded on the Australian Securities Exchange. NOVONIX is a Brisbane, Australia-based company that develops technology and supplies materials for lithium-ion batteries. Since we do not have significant influence over the operating and financial policies of NOVONIX and the shares we own have a readily determinable fair value, our investment is recorded at fair value at the end of each reporting period. The fair value of our investment is recorded in the “Investments and long-term receivables” line item on our consolidated balance sheet. The change in the fair value of our investment due to fluctuations in NOVONIX’s stock price, or unrealized investment gains (losses), is recorded in the “Other income (loss)” line item of our consolidated statement of operations, while changes due to foreign currency fluctuations are recorded in the “Foreign currency transaction gains” line item on our consolidated statement of operations. The fair value of our investment in NOVONIX was $362 million at March 31, 2022. The fair value of our investment in NOVONIX declined by $158 million during the three months ended March 31, 2022, reflecting an unrealized investment loss of $169 million, partially offset by an unrealized foreign currency gain of $11 million. See Note 12—Fair Value Measurements, for additional information regarding the recurring fair value measurement of our investment in NOVONIX.

Related Party Loans

We and our co-venturer provided member loans to WRB Refining LP (WRB). At March 31, 2022, our 50% share of the outstanding member loan balance, including accrued interest, was $597 million.

Earnings Per Share [Abstract]

Earnings (Loss) Per Share

Earnings (Loss) Per Share

The numerator of basic earnings (loss) per share (EPS) is net income (loss) attributable to Phillips 66, adjusted for noncancelable dividends paid on unvested share-based employee awards during the vesting period (participating securities). The denominator of basic EPS is the sum of the daily weighted-average number of common shares outstanding during the periods presented and fully vested stock and unit awards that have not yet been issued as common stock. The numerator of diluted EPS is also based on net income (loss) attributable to Phillips 66, which is reduced by dividend equivalents paid on participating securities for which the dividends are more dilutive than the participation of the awards in the earnings (loss) of the periods presented. To the extent unvested stock, unit or option awards and vested unexercised stock options are dilutive, they are included with the weighted-average common shares outstanding in the denominator. Treasury stock is excluded from the denominator in both basic and diluted EPS.

2022 Activities

Debt Repayments

In early April 2022, upon maturity, Phillips 66 repaid its 4.300% senior notes with an aggregate principal amount of $1.0 billion and Phillips 66 Partners repaid its $450 million term loan.

Debt Exchange

On April 6, 2022, Phillips 66 Company, a wholly owned subsidiary of Phillips 66, announced offers to exchange (the Exchange Offers) all validly tendered notes of seven different series of notes issued by Phillips 66 Partners (collectively, the Old Notes), with an aggregate principal amount of approximately $3.5 billion, for notes to be issued by Phillips 66 Company (collectively, the New Notes). The New Notes will be fully and unconditionally guaranteed by Phillips 66 and will rank equally with Phillips 66 Company’s other unsecured and unsubordinated indebtedness, and the guarantees will rank equally with Phillips 66’s other unsecured and unsubordinated indebtedness. The Exchange Offers will expire on May 3, 2022, unless such date is extended (the Expiration Date). Phillips 66 Company currently expects the settlement of the Exchange Offers to occur on May 5, 2022, unless the Expiration Date is extended.

The New Notes will have the same interest rates, interest payment dates and maturity dates as the Old Notes. In addition, holders that validly tender before the end of the early participation period on April 19, 2022 (the Early Participation Date), will receive New Notes with an aggregate principal amount equivalent to the Old Notes, while holders that validly tender after the Early Participation Date, but before the Expiration Date, will receive New Notes with an aggregate principal amount that is 3% less than the Old Notes.

Through the end of the early participation period on April 19, 2022, Old Notes with an aggregate principal amount of approximately $3.2 billion had been validly tendered for exchange.

2021 Activities

In February 2021, Phillips 66 repaid $500 million outstanding principal balance of its floating-rate senior notes upon maturity.

Guarantees

Guarantees [Abstract]

Guarantees

Guarantees

At March 31, 2022, we were liable for certain contingent obligations under various contractual arrangements as described below. We recognize a liability for the fair value of our obligation as a guarantor for newly issued or modified guarantees. Unless the carrying amount of the liability is noted below, we have not recognized a liability either because the guarantees were issued prior to December 31, 2002, or because the fair value of the obligation is immaterial. In addition, unless otherwise stated, we are not currently performing with any significance under the guarantees and expect future performance to be either immaterial or have only a remote chance of occurrence.

Lease Residual Value Guarantees

Under the operating lease agreement for our headquarters facility in Houston, Texas, we have the option, at the end of the lease term in September 2025, to request to renew the lease, purchase the facility or assist the lessor in marketing it for resale. We have a residual value guarantee associated with the operating lease agreement with a maximum potential future exposure of $514 million at March 31, 2022. We also have residual value guarantees associated with railcar and airplane leases with maximum potential future exposures totaling $221 million. These leases have remaining terms of up to ten years.

Guarantees of Joint Venture Obligations

In March 2019, Phillips 66 Partners and its co-venturers in Dakota Access provided a CECU in conjunction with a senior unsecured notes offering. See Note 5—Investments, Loans and Long-Term Receivables, for additional information on Dakota Access and the CECU.

At March 31, 2022, we also had other guarantees outstanding primarily for our portion of certain joint venture debt, which have remaining terms of up to four years. The maximum potential future exposures under these guarantees were approximately $133 million. Payment would be required if a joint venture defaults on its obligations.

Indemnifications

Over the years, we have entered into various agreements to sell ownership interests in certain corporations, joint ventures and assets that gave rise to indemnification. Agreements associated with these sales include indemnifications for taxes, litigation, environmental liabilities, permits and licenses, employee claims, and real estate tenant defaults. The provisions of these indemnifications vary greatly. The majority of these indemnifications are related to environmental issues, which generally have indefinite terms and potentially unlimited exposure. At March 31, 2022, and December 31, 2021, the carrying amount of recorded indemnifications was $146 million and $144 million, respectively.

We amortize the indemnification liability over the relevant time period, if one exists, based on the facts and circumstances surrounding each type of indemnity. In cases where the indemnification term is indefinite, we will reverse the liability when we have information to support the reversal. Although it is reasonably possible future payments may exceed amounts recorded, due to the nature of the indemnifications, it is not possible to make a reasonable estimate of the maximum potential amount of future payments. At March 31, 2022, and December 31, 2021, environmental accruals for known contamination of $109 million and $106 million, respectively, were included in the carrying amount of the recorded indemnifications noted above. These environmental accruals were primarily included in the “Asset retirement obligations and accrued environmental costs” line item on our consolidated balance sheet. For additional information about environmental liabilities, see Note 10—Contingencies and Commitments.

Indemnification and Release Agreement

In 2012, in connection with our separation from ConocoPhillips, we entered into an Indemnification and Release Agreement. This agreement governs the treatment between ConocoPhillips and us of matters relating to indemnification, insurance, litigation responsibility and management, and litigation document sharing and cooperation arising in connection with the separation. Generally, the agreement provides for cross indemnities principally designed to place financial responsibility for the obligations and liabilities of our business with us and financial responsibility for the obligations and liabilities of ConocoPhillips’ business with ConocoPhillips. The agreement also establishes procedures for handling claims subject to indemnification and related matters.

Commitments and Contingencies Disclosure [Abstract]

Contingencies and Commitments

Contingencies and Commitments

A number of lawsuits involving a variety of claims that arose in the ordinary course of business have been filed against us or are subject to indemnifications provided by us. We also may be required to remove or mitigate the effects on the environment of the placement, storage, disposal or release of certain chemical, mineral and petroleum substances at various active and inactive sites. We regularly assess the need for financial recognition or disclosure of these contingencies. In the case of all known contingencies (other than those related to income taxes), we accrue a liability when the loss is probable and the amount is reasonably estimable. If a range of amounts can be reasonably estimated and no amount within the range is a better estimate than any other amount, then the minimum of the range is accrued. We do not reduce these liabilities for potential insurance or third-party recoveries. If applicable, we accrue receivables for probable insurance or other third-party recoveries. In the case of income tax-related contingencies, we use a cumulative probability-weighted loss accrual in cases where sustaining a tax position is uncertain.

Based on currently available information, we believe it is remote that future costs related to known contingent liability exposures will exceed current accruals by an amount that would have a material adverse impact on our consolidated financial statements. As we learn new facts concerning contingencies, we reassess our position both with respect to accrued liabilities and other potential exposures. Estimates particularly sensitive to future changes include contingent liabilities recorded for environmental remediation, tax and legal matters. Estimated future environmental remediation costs are subject to change due to such factors as the uncertain magnitude of cleanup costs, the unknown time and extent of such remedial actions that may be required, and the determination of our liability in proportion to that of other potentially responsible parties. Estimated future costs related to tax and legal matters are subject to change as events evolve and as additional information becomes available during the administrative and litigation processes.

Environmental

We are subject to international, federal, state and local environmental laws and regulations. When we prepare our consolidated financial statements, we record accruals for environmental liabilities based on management’s best estimates, using information available at the time. We measure estimates and base contingent liabilities on currently available facts, existing technology and presently enacted laws and regulations, taking into account stakeholder and business considerations. When measuring contingent environmental liabilities, we also consider our prior experience in remediation of contaminated sites, other companies’ cleanup experience, and data released by the EPA or other organizations. We consider unasserted claims in our determination of environmental liabilities, and we accrue them in the period they are both probable and reasonably estimable.

Although liability for environmental remediation costs is generally joint and several for federal sites and frequently so for state sites, we are usually only one of many companies alleged to have liability at a particular site. Due to such joint and several liabilities, we could be responsible for all cleanup costs related to any site at which we have been designated as a potentially responsible party. We have been successful to date in sharing cleanup costs with other financially sound companies. Many of the sites for which we are potentially responsible are still under investigation by the EPA or the state agencies concerned. Prior to actual cleanup, those potentially responsible normally assess the site conditions, apportion responsibility and determine the appropriate remediation. In some instances, we may have no liability or may attain a settlement of liability. Where it appears that other potentially responsible parties may be financially unable to bear their proportional share, we consider this inability in estimating our potential liability, and we adjust our accruals accordingly. As a result of various acquisitions in the past, we assumed certain environmental obligations. Some of these environmental obligations are mitigated by indemnifications made by others for our benefit, although some of the indemnifications are subject to dollar and time limits.

We are currently participating in environmental assessments and cleanups at numerous federal Superfund and comparable state sites. After an assessment of environmental exposures for cleanup and other costs, we make accruals on an undiscounted basis (except those pertaining to sites acquired in a business combination, which we record on a discounted basis) for planned investigation and remediation activities for sites where it is probable future costs will be incurred and these costs can be reasonably estimated. At March 31, 2022, and December 31, 2021, our total environmental accruals were $436 million. We expect to incur a substantial amount of these expenditures within the next 30 years. We have not reduced these accruals for possible insurance recoveries. In the future, we may be involved in additional environmental assessments, cleanups and proceedings.

Legal Proceedings

Our legal organization applies its knowledge, experience and professional judgment to the specific characteristics of our cases, employing a litigation management process to manage and monitor the legal proceedings against us. Our process facilitates the early evaluation and quantification of potential exposures in individual cases and enables the tracking of those cases that have been scheduled for trial and/or mediation. Based on professional judgment and experience in using these litigation management tools and available information about current developments in all our cases, our legal organization regularly assesses the adequacy of current accruals and determines if adjustment of existing accruals, or establishment of new accruals, is required.

Other Contingencies

We have contingent liabilities resulting from throughput agreements with pipeline and processing companies not associated with financing arrangements. Under these agreements, we may be required to provide any such company with additional funds through advances and penalties for fees related to throughput capacity not utilized.

At March 31, 2022, we had performance obligations secured by letters of credit and bank guarantees of $1,546 million related to various purchase and other commitments incident to the ordinary conduct of business.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives and Financial Instruments

Derivatives and Financial Instruments

Derivative Instruments

We use financial and commodity-based derivative contracts to manage exposures to fluctuations in commodity prices, interest rates and foreign currency exchange rates, or to capture market opportunities. Because we do not apply hedge accounting for commodity derivative contracts, all realized and unrealized gains and losses from commodity derivative contracts are recognized in our consolidated statement of operations. Gains and losses from derivative contracts held for trading not directly related to our physical business are reported net in the “Other income” line item on our consolidated statement of operations. Cash flows from all our derivative activity for the periods presented appear in the operating section on our consolidated statement of cash flows.

Purchase and sales contracts with firm minimum notional volumes for commodities that are readily convertible to cash are recorded on our consolidated balance sheet as derivatives unless the contracts are eligible for, and we elect, the normal purchases and normal sales exception, whereby the contracts are recorded on an accrual basis. We generally apply the normal purchases and normal sales exception to eligible crude oil, refined petroleum product, NGL, natural gas, renewable feedstock, and power commodity contracts to purchase or sell quantities we expect to use or sell in the normal course of business. All other derivative instruments are recorded at fair value on our consolidated balance sheet. For further information on the fair value of derivatives, see Note 12—Fair Value Measurements.

Commodity Derivative Contracts—We sell into or receive supply from the worldwide crude oil, refined petroleum product, NGL, natural gas, renewable feedstock, and electric power markets, exposing our revenues, purchases, cost of operating activities and cash flows to fluctuations in the prices for these commodities. Generally, our policy is to remain exposed to the market prices of commodities; however, we use futures, forwards, swaps and options in various markets to balance physical systems, meet customer needs, manage price exposures on specific transactions, and do a limited amount of trading not directly related to our physical business, all of which may reduce our exposure to fluctuations in market prices. We also use the market knowledge gained from these activities to capture market opportunities such as moving physical commodities to more profitable locations, storing commodities to capture seasonal or time premiums, and blending commodities to capture quality upgrades.

The following table indicates the consolidated balance sheet line items that include the fair values of commodity derivative assets and liabilities. The balances in the following table are presented on a gross basis, before the effects of counterparty and collateral netting. However, we have elected to present our commodity derivative assets and liabilities with the same counterparty on a net basis on our consolidated balance sheet when the legal right of offset exists.

At March 31, 2022, and December 31, 2021, there was no material cash collateral received or paid that was not offset on our consolidated balance sheet.

The realized and unrealized gains (losses) incurred from commodity derivatives, and the line items where they appear on our consolidated statement of operations, were:

The following table summarizes our material net exposures resulting from outstanding commodity derivative contracts. These financial and physical derivative contracts are primarily used to manage price exposure on our underlying operations. The underlying exposures may be from nonderivative positions such as inventory volumes. Financial derivative contracts may also offset physical derivative contracts, such as forward purchase and sales contracts. The percentage of our derivative contract volumes expiring within the next 12 months was more than 95% at March 31, 2022, and December 31, 2021.

Credit Risk from Derivative Instruments

The credit risk from our derivative contracts, such as forwards and swaps, derives from the counterparty to the transaction. Individual counterparty exposure is managed within predetermined credit limits and includes the use of cash-call margins when appropriate, thereby reducing the risk of significant nonperformance. We also use futures, swaps and option contracts that have a negligible credit risk because these trades are cleared with an exchange clearinghouse and subject to mandatory margin requirements, typically on a daily basis, until settled.

Certain of our derivative instruments contain provisions that require us to post collateral if the derivative exposure exceeds a threshold amount. We have contracts with fixed threshold amounts and other contracts with variable threshold amounts that are contingent on our credit rating. The variable threshold amounts typically decline for lower credit ratings, while both the variable and fixed threshold amounts typically revert to zero if our credit ratings fall below investment grade. Cash is the primary collateral in all contracts; however, many contracts also permit us to post letters of credit as collateral.

The aggregate fair values of all derivative instruments with such credit-risk-related contingent features that were in a liability position were immaterial at March 31, 2022, and December 31, 2021.

Fair Value Measurements

Fair Value Measurements

Recurring Fair Value Measurements

We carry certain assets and liabilities at fair value, which we measure at the reporting date using the price that would be received to sell an asset or paid to transfer a liability (i.e., an exit price), and disclose the quality of these fair values based on the valuation inputs used in these measurements under the following hierarchy:

•Level 1: Fair value measured with unadjusted quoted prices from an active market for identical assets or liabilities.

•Level 2: Fair value measured either with: (1) adjusted quoted prices from an active market for similar assets or liabilities; or (2) other valuation inputs that are directly or indirectly observable.

•Level 3: Fair value measured with unobservable inputs that are significant to the measurement.

We classify the fair value of an asset or liability based on the significance of its observable or unobservable inputs to the measurement. However, the fair value of an asset or liability initially reported as Level 3 will be subsequently reported as Level 2 if the unobservable inputs become inconsequential to its measurement or corroborating market data becomes available. Conversely, an asset or liability initially reported as Level 2 will be subsequently reported as Level 3 if corroborating market data becomes unavailable.

We used the following methods and assumptions to estimate the fair value of financial instruments:

•Cash and cash equivalents—The carrying amount reported on our consolidated balance sheet approximates fair value.

•Accounts and notes receivable—The carrying amount reported on our consolidated balance sheet approximates fair value.

•Derivative instruments—We fair value our exchange-traded contracts based on quoted market prices obtained from the New York Mercantile Exchange, the Intercontinental Exchange or other exchanges, and classify them as Level 1 in the fair value hierarchy. When exchange-cleared contracts lack sufficient liquidity, or are valued using either adjusted exchange-provided prices or nonexchange quotes, we classify those contracts as Level 2.

Physical commodity forward purchase and sales contracts and over-the-counter (OTC) financial swaps are generally valued using forward quotes provided by brokers and price index developers, such as Platts and Oil Price Information Service. We corroborate these quotes with market data and classify the resulting fair values as Level 2. When forward market prices are not available, we estimate fair value using the forward price of a similar commodity, adjusted for the difference in quality or location. In certain less liquid markets or for longer-term contracts, forward prices are not as readily available. In these circumstances, physical commodity purchase and sales contracts and OTC swaps are valued using internally developed methodologies that consider historical relationships among various commodities that result in management’s best estimate of fair value. We classify these contracts as Level 3. Physical and OTC commodity options are valued using industry-standard models that consider various assumptions, including quoted forward prices for commodities, time value, volatility factors and contractual prices for the underlying instruments, as well as other relevant economic measures. The degree to which these inputs are observable in the forward markets determines whether the options are classified as Level 2 or 3. We use a midmarket pricing convention (the midpoint between bid and ask prices). When appropriate, valuations are adjusted to reflect credit considerations, generally based on available market evidence.

We determine the fair value of our interest rate swaps based on observable market valuations for interest rate swaps that have notional amounts, terms and pay and reset frequencies similar to ours.

•Rabbi trust assets—These deferred compensation investments are measured at fair value using unadjusted quoted prices available from national securities exchanges and are therefore categorized as Level 1 in the fair value hierarchy.

•Investment in NOVONIX—Our investment in NOVONIX is measured at fair value using unadjusted quoted prices available from the Australian Securities Exchange and is therefore categorized as Level 1 in the fair value hierarchy.

•Debt—The carrying amount of our floating-rate debt approximates fair value. The fair value of our fixed-rate debt is estimated based on observable market prices.

The following tables display the fair value hierarchy for our financial assets and liabilities either accounted for or disclosed at fair value on a recurring basis. These values are determined by treating each contract as the fundamental unit of account; therefore, derivative assets and liabilities with the same counterparty are shown on a gross basis in the hierarchy sections of these tables, before the effects of counterparty and collateral netting. The following tables also reflect the effect of netting derivative assets and liabilities with the same counterparty for which we have the legal right of offset and collateral netting.

The carrying values and fair values by hierarchy of our financial assets and liabilities, either carried or disclosed at fair value, including any effects of counterparty and collateral netting, were:

Nonrecurring Fair Value Measurements

Equity Investments

In the first quarter of 2021, Phillips 66 Partners wrote down the book value of its investment in Liberty to estimated fair value using a Level 3 nonrecurring fair value measurement. This nonrecurring measurement was based on the estimated fair value of Phillip 66 Partners’ share of the joint venture’s pipeline assets and net working capital at March 31, 2021. See Note 5—Investments, Loans and Long-Term Receivables, for more information regarding Phillips 66 Partners’ transfer of its ownership in Liberty to its co-venturer in April 2021.

Phillips 66 Partners LP

Phillips 66 Partners LP

On March 9, 2022, we completed the previously announced merger between us and Phillips 66 Partners. The merger resulted in the acquisition of all limited partnership interests in Phillips 66 Partners not already owned by us in exchange for approximately 42 million shares of Phillips 66 common stock issued from treasury stock. Phillips 66 Partners common unitholders received 0.50 shares of Phillips 66 common stock for each outstanding Phillips 66 Partners common unit. Phillips 66 Partners’ perpetual convertible preferred units were converted into common units at a premium to the original issuance price prior to being exchanged for Phillips 66 common stock. Upon closing, Phillips 66 Partners became a wholly owned subsidiary of Phillips 66 and its common units are no longer publicly traded.

The merger was accounted for as an equity transaction and resulted in decreases to “Treasury stock” of $3,380 million, “Noncontrolling interests” of $2,163 million, “Capital in excess of par” of $869 million, “Deferred income taxes” of $355 million, and “Cash and cash equivalents” of $2 million, and an increase to “Other accruals” of $5 million on our consolidated balance sheet.

Earnings (Loss) Per Share (Policies)

3 Months Ended

Mar. 31, 2022

Earnings Per Share [Abstract]

Earnings (Loss) Per Share

Earnings (Loss) Per Share The numerator of basic earnings (loss) per share (EPS) is net income (loss) attributable to Phillips 66, adjusted for noncancelable dividends paid on unvested share-based employee awards during the vesting period (participating securities). The denominator of basic EPS is the sum of the daily weighted-average number of common shares outstanding during the periods presented and fully vested stock and unit awards that have not yet been issued as common stock. The numerator of diluted EPS is also based on net income (loss) attributable to Phillips 66, which is reduced by dividend equivalents paid on participating securities for which the dividends are more dilutive than the participation of the awards in the earnings (loss) of the periods presented. To the extent unvested stock, unit or option awards and vested unexercised stock options are dilutive, they are included with the weighted-average common shares outstanding in the denominator. Treasury stock is excluded from the denominator in both basic and diluted EPS.

Contingencies and Commitments

A number of lawsuits involving a variety of claims that arose in the ordinary course of business have been filed against us or are subject to indemnifications provided by us. We also may be required to remove or mitigate the effects on the environment of the placement, storage, disposal or release of certain chemical, mineral and petroleum substances at various active and inactive sites. We regularly assess the need for financial recognition or disclosure of these contingencies. In the case of all known contingencies (other than those related to income taxes), we accrue a liability when the loss is probable and the amount is reasonably estimable. If a range of amounts can be reasonably estimated and no amount within the range is a better estimate than any other amount, then the minimum of the range is accrued. We do not reduce these liabilities for potential insurance or third-party recoveries. If applicable, we accrue receivables for probable insurance or other third-party recoveries. In the case of income tax-related contingencies, we use a cumulative probability-weighted loss accrual in cases where sustaining a tax position is uncertain.

Based on currently available information, we believe it is remote that future costs related to known contingent liability exposures will exceed current accruals by an amount that would have a material adverse impact on our consolidated financial statements. As we learn new facts concerning contingencies, we reassess our position both with respect to accrued liabilities and other potential exposures. Estimates particularly sensitive to future changes include contingent liabilities recorded for environmental remediation, tax and legal matters. Estimated future environmental remediation costs are subject to change due to such factors as the uncertain magnitude of cleanup costs, the unknown time and extent of such remedial actions that may be required, and the determination of our liability in proportion to that of other potentially responsible parties. Estimated future costs related to tax and legal matters are subject to change as events evolve and as additional information becomes available during the administrative and litigation processes.

Recurring Fair Value Measurements

Recurring Fair Value Measurements

We carry certain assets and liabilities at fair value, which we measure at the reporting date using the price that would be received to sell an asset or paid to transfer a liability (i.e., an exit price), and disclose the quality of these fair values based on the valuation inputs used in these measurements under the following hierarchy:

•Level 1: Fair value measured with unadjusted quoted prices from an active market for identical assets or liabilities.

•Level 2: Fair value measured either with: (1) adjusted quoted prices from an active market for similar assets or liabilities; or (2) other valuation inputs that are directly or indirectly observable.

•Level 3: Fair value measured with unobservable inputs that are significant to the measurement.

We classify the fair value of an asset or liability based on the significance of its observable or unobservable inputs to the measurement. However, the fair value of an asset or liability initially reported as Level 3 will be subsequently reported as Level 2 if the unobservable inputs become inconsequential to its measurement or corroborating market data becomes available. Conversely, an asset or liability initially reported as Level 2 will be subsequently reported as Level 3 if corroborating market data becomes unavailable.

We used the following methods and assumptions to estimate the fair value of financial instruments:

•Cash and cash equivalents—The carrying amount reported on our consolidated balance sheet approximates fair value.

•Accounts and notes receivable—The carrying amount reported on our consolidated balance sheet approximates fair value.

•Derivative instruments—We fair value our exchange-traded contracts based on quoted market prices obtained from the New York Mercantile Exchange, the Intercontinental Exchange or other exchanges, and classify them as Level 1 in the fair value hierarchy. When exchange-cleared contracts lack sufficient liquidity, or are valued using either adjusted exchange-provided prices or nonexchange quotes, we classify those contracts as Level 2.

Physical commodity forward purchase and sales contracts and over-the-counter (OTC) financial swaps are generally valued using forward quotes provided by brokers and price index developers, such as Platts and Oil Price Information Service. We corroborate these quotes with market data and classify the resulting fair values as Level 2.

The following table indicates the consolidated balance sheet line items that include the fair values of commodity derivative assets and liabilities. The balances in the following table are presented on a gross basis, before the effects of counterparty and collateral netting. However, we have elected to present our commodity derivative assets and liabilities with the same counterparty on a net basis on our consolidated balance sheet when the legal right of offset exists.

Summary of Material Net Exposures and Notional Amount of Derivative Contracts

The following table summarizes our material net exposures resulting from outstanding commodity derivative contracts. These financial and physical derivative contracts are primarily used to manage price exposure on our underlying operations. The underlying exposures may be from nonderivative positions such as inventory volumes. Financial derivative contracts may also offset physical derivative contracts, such as forward purchase and sales contracts. The percentage of our derivative contract volumes expiring within the next 12 months was more than 95% at March 31, 2022, and December 31, 2021.
