Notes to Consolidated Financial StatementsPhillips 66
 
Note 1—Interim Financial Information

The interim financial information presented in the financial statements included in this report is unaudited 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 2017 Annual Report on Form 10-K. The results of operations for the three and sixnine months ended JuneSeptember 30, 2018, are not necessarily indicative of the results to be expected for the full year. Certain prior period financial information has been recast to reflect the current year’s presentation.


Note 2—Changes in Accounting Principles

Effective January 1, 2018, we adopted Financial Accounting Standards Board (FASB) Accounting Standards Update (ASU) No. 2017-05, “Other Income—Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20),” which clarifies the scope and accounting for the sale or transfer of nonfinancial assets and in substance nonfinancial assets to noncustomers, including partial sales.  This ASU eliminated the use of carryover basis for most nonmonetary exchanges, including contributions of assets to equity-method joint ventures, and could result in the entity recognizing a gain or loss on the sale or transfer of nonfinancial assets.  At the time of adoption, there was no impact on our consolidated financial statements from adopting this ASU.

Effective January 1, 2018, we adopted ASU No. 2017-01, “Business Combinations (Topic 805): Clarifying the Definition of a Business,” which clarifies the definition of a business with the objective of adding guidance to assist in evaluating whether transactions should be accounted for as acquisitions of assets or businesses. The amendment provides a screen for determining when a transaction involves an acquisition of a business. If substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset, or a group of similar identifiable assets, then the screen is met and the transaction is not considered an acquisition of a business. If the screen is not met, the amendment requires that to be considered a business, the operation must include at a minimum an input and a substantive process that together significantly contribute to the ability to create an output. The guidance may reduce the number of future transactions accounted for as business acquisitions. At the time of adoption, there was no impact on our consolidated financial statements from adopting this ASU.

Effective January 1, 2018, we adopted ASU No. 2016-16, “Income Taxes (Topic 740): Intra-Entity Asset Transfers of Assets Other Than Inventory.”  This ASU requires the income tax consequences of an intra-entity transfer of an asset, other than inventory, to be recognized when the transfer occurs.  At the time of adoption, this ASU did not have a material impact on our consolidated financial statements.

Effective January 1, 2018, we adopted ASU No. 2016-01, “Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities.” The majority of this ASU’s provisions amend only the presentation or disclosures of financial instruments; however, one provision could also affect net income. Equity investments carried under the cost method or the lower of cost or fair value method of accounting, in accordance with previous generally accepted accounting principles in the United States (GAAP), will have to be carried at fair value with changes in fair value recorded in net income. For equity investments that do not have readily determinable fair values, a company may elect to carry such investments at cost less impairments, if any, adjusted up or down for price changes in similar financial instruments issued by the investee, when and if observed. At the time of adoption, this ASU did not have a material impact on our consolidated financial statements.





Effective January 1, 2018, we adopted ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606),” using the modified retrospective transition method applied to all contracts. Under the new revenue recognition guidance, recognition of revenue involves a multiple step approach including (i) identifying the contract, (ii) identifying the separate performance obligations, (iii) determining the transaction price, (iv) allocating the price to the performance obligations and (v) recognizing the revenue as the obligations are satisfied. Additional disclosures are required to enable users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers.

We recorded noncash cumulative effect adjustments to our opening total equity balance as of January 1, 2018, to increase retained earnings by $35 million, net of $11 million of income taxes, and noncontrolling interests by $13 million. These adjustments primarily reflected amounts recorded by our equity-method investees related to contracts that contain tier-pricing and minimum volume commitments with recovery provisions. One of our Midstream segment equity-method investees will adopt this ASU in 2019, and we do not expect theirits adoption to have a material impact on our consolidated financial statements.

In addition, prospectively from January 1, 2018, our presentation of excise taxes on sales of petroleum products changed to a net basis from a gross basis. As a result, the “Sales and other operating revenues” and “Taxes other than income taxes” lines on our consolidated statement of income for the three and sixnine months ended JuneSeptember 30, 2018, are not presented on a comparable basis to the three and sixnine months ended JuneSeptember 30, 2017. See Note 3—Sales and Other Operating Revenues, for more information on our presentation of excise taxes on sales of petroleum products.


Note 3—Sales and Other Operating Revenues

Our revenues are primarily associated with sales of refined petroleum products, crude oil and natural gas liquids (NGL), refined petroleum and chemical products, and other items.. Each gallon, or other unit of measure of product, is separately identifiable and represents a distinct performance obligation to which the transaction price is allocated. The transaction prices of our contracts with customers are either fixed or variable, with variable pricing based upon various market indices. For our contracts that include variable consideration, we utilize the variable consideration allocation exception, whereby the variable consideration is only allocated to the performance obligations that are satisfied during the period. The related revenue is recognized at a point in time when control passes to the customer, which is when title and the risk of ownership passes to the customer and physical delivery of goods occurs, either immediately or within a fixed delivery schedule that is reasonable and customary in the industry.

Effective for reporting periods ending after our adoption of ASU No. 2014-09 on January 1, 2018, excise taxes on sales of petroleum products charged to our customers are presented net of excise taxes on sales of petroleum products owed to governmental authorities in the “Taxes other than income taxes” line on our consolidated statement of income. For reporting periods ending prior to January 1, 2018, excise taxes on sales of petroleum products charged to our customers are presented in the “Sales and other operating revenues” line on our consolidated statement of income, and excise taxes on sales of petroleum products owed to governmental authorities are presented in the “Taxes other than income taxes” line on our consolidated statement of income. See Note 2—Changes in Accounting Principles, for more information regarding our adoption of this ASU.

Revenues associated with pipeline transportation services are recognized at a point in time when the volumes are delivered based on contractual rates. Revenues associated with terminaling and storage services are recognized over time as the services are performed based on throughput volume or capacity utilization at contractual rates.

Our products and services are billed and payments are received typically on a monthly basis, which may vary based upon the product or service offered.

Contract-Related Assets and Liabilities
At JuneSeptember 30, 2018, and January 1, 2018, receivables from contracts with customers were $5.9$6.5 billion and $6.2 billion, respectively. Significant non-customer 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 JuneSeptember 30, 2018, and January 1, 2018, our asset balances related to such payments were $220$237 million and $208 million, respectively.

Our contract liabilities represent advances from our customers prior to product or service delivery. At JuneSeptember 30, 2018, and January 1, 2018, 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, most of which expire by 2021. The remaining performance obligations related to these minimum volume commitment contracts were immaterial at JuneSeptember 30, 2018.

Note 5—Business Combinations

Merey Sweeny, L.P. (MSLP) is a limited partnership that owns a delayed coker and related facilities at the Sweeny Refinery. In February 2017, we began accounting for MSLP as a consolidated subsidiary because the exercise of a call right triggered by certain defaults by the co-venturer, Petróleos de Venezuela S.A. (PDVSA), with respect to supply of crude oil to the Sweeny Refinery ceased to be subject to legal challenge. The purchase price for PDVSA’s 50 percent ownership interest was determined by a contractual formula. Because the distributions PDVSA received from MSLP exceeded the amounts it contributed to MSLP, the contractual formula required no cash consideration for the acquisition. 

Based on a third-party appraisal of the fair value of MSLP’s net assets, utilizing discounted cash flows and replacement costs, the acquisition of PDVSA’s 50 percent interest resulted in the recognition of a pre-tax gain of $423 million during the three months ended March 31, 2017.  This gain was included in the “Other income” line on our consolidated statement of income. The fair value of our original equity interest in MSLP immediately prior to the deemed acquisition was $145 million. As a result of the transaction, weWe also recorded $318 million of restricted cash, $250 million of properties, plants and equipment (PP&E) and $238 million of debt, as well as a net $93 million for the elimination of our equity investment in MSLP and net intercompany payables.payables related to this transaction. Our acquisition accounting was finalized in the first quarter of 2017.

The results of MSLP were included in our Refining segment until October 2017, when we contributed our 100 percent interest in MSLP to Phillips 66 Partners LP (Phillips 66 Partners), which is includeda consolidated subsidiary in our Midstream segment.

Gray Oak Pipeline, LLC
Phillips 66 Partners has a 75 percent ownership interest in Gray Oak Pipeline, LLC (Gray Oak), an entity formed to develop and construct the Gray Oak Pipeline system which, upon completion, will provide crude oil transportation from the Permian Basin and Eagle Ford to destinations in the Corpus Christi and Sweeny/Freeport markets on the Texas Gulf Coast. The pipeline is expected to be placed in service by the end of 2019.

Gray Oak is considered a variable interest entity (VIE) because it does not have sufficient equity at risk to fully fund the construction of all assets required for principal operations. Phillips 66 Partners has determined it is not the primary beneficiary because it and its co-venturer jointly direct the activities of Gray Oak that most significantly impact economic performance. At JuneSeptember 30, 2018, Phillips 66 Partners’ maximum exposure to loss was $28$72 million, which represented the aggregate book value of its equity investment in Gray Oak.

Rockies Express Pipeline LLC
In July 2018, Rockies Express Pipeline LLC (REX) repaid $550 million of its debt, reducing its total debt to approximately $2.0$2.1 billion.  REX funded the repayment through member cash contributions.  Our 25 percent share was approximately $138 million which weand was contributed to REX in July 2018.

Related Party Loans and Advances
During the three months ended March 31, 2017, we received payment of the $250 million outstanding sponsor loans to the Dakota Access, LLC and Energy Transfer Crude Oil Company, LLC joint ventures. We also received payment of the $75 million outstanding principal balance of the partner loan we made to WRB Refining LP (WRB) in 2016. These cash inflows, totaling $325 million, are included in the “Collection of advances/loans—related parties” line on our consolidated statement of cash flows.

Note 8—Earnings Per Share

The numerator of basic earnings per share (EPS) is net income attributable to Phillips 66, reduced by 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 attributable to Phillips 66, which is reduced only by dividend equivalents paid on participating securities for which the dividends are more dilutive than the participation of the awards in the earnings 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.

Note 9—Debt

Debt Issuances
In March 2018, Phillips 66 closed on a public offering of $1,500 million aggregate principal amount of unsecured notes consisting of:

$500 million of floating-rate Senior Notes due 2021. Interest on these notes is equal to the three-month London Interbank Offered Rate (LIBOR) plus 0.60% per annum and is payable quarterly in arrears on February 26, May 26, August 26 and November 26, beginning on May 29, 2018.

$800 million of 3.900% Senior Notes due 2028. Interest on these notes is payable semiannually on March 15 and September 15 of each year, beginning on September 15, 2018.

An additional $200 million of our 4.875% Senior Notes due 2044. Interest on these notes is payable semiannually on May 15 and November 15 of each year, beginning on May 15, 2018.
 
These notes are guaranteed by Phillips 66 Company, a wholly owned subsidiary. Phillips 66 used the net proceeds from the issuance of these notes and cash on hand to repay commercial paper borrowings during the three months ended March 31, 2018, and for general corporate purposes. The commercial paper borrowings during the three months ended March 31, 2018, were primarily used to repurchase shares of our common stock; see Note 16—Treasury Stock for additional information.

Debt Repayments
In June 2018, Phillips 66 repaid $250 million of the $450 million outstanding under its three-year term loan facility due 2020.

Debt Reclassifications
During the three months ended June 30,In April 2018, Phillips 66’s $300 million of floating-rate notes due 2019 were reclassified from long-term to short-term debt.


Note 10—Guarantees

At JuneSeptember 30, 2018, 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 guarantee and expect future performance to be either immaterial or have only a remote chance of occurrence.

Guarantees of Joint Venture Debt
In December 2016, as part of the restructuring within DCP Midstream, LLC (DCP Midstream), we issued a guarantee, effective January 1, 2017, to support the debt DCP Midstream issued during the three months ended March 31, 2017. Payment would be required if DCP Midstream defaults on this debt obligation, which matures in December 2019. At JuneSeptember 30, 2018, the maximum potential amount of future payments to third parties under the guarantee is estimated to be $125$105 million. Payment would be required if DCP Midstream defaults on this debt obligation, which matures in December 2019.

At JuneSeptember 30, 2018, we had other guarantees outstanding for our portion of certain joint venture debt obligations, which have remaining terms of up to seven years. Payment would be required if a joint venture defaults on its debt obligations. The maximum potential amount of future payments to third parties under these guarantees was approximately $131$134 million. Payment would be required if a joint venture defaults on its debt obligations.






Other Guarantees
Under the operating lease agreement on our headquarters facility in Houston, Texas, we have a residual value guarantee with a maximum future exposure of $554 million. The operating lease term ends in June 2021 and provides us the option, at the end of the lease term, to request to renew the lease, purchase the facility or assist the lessor in marketing it for resale.

We also have residual value guarantees associated with railcar and airplane leases with maximum future exposures totaling $291$319 million, which have remaining terms of up to five years. For one of our railcar leases, we estimated a total residual value deficiency of $56 million based on a third-party appraisal of the railcars’ expected fair value at the end of theirthe lease term in May 2019. The total residual value deficiency is our estimate of the amount we will owe to the lessor at the end of the lease term and is recognized as expense over the remaining lease term. During the sixnine months ended JuneSeptember 30, 2018, we recognized $12$19 million of expense related to the residual value deficiency.  At JuneSeptember 30, 2018, the remaining unrecognized residual value deficiency was $24$17 million. 

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 and employee claims, as well as real estate indemnity against 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 JuneSeptember 30, 2018, the carrying amount recorded for indemnifications was $187$178 million.

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 that the liability was essentially relieved or amortize the liability over an appropriate time period as the fair value of our indemnification exposure declines. 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 JuneSeptember 30, 2018, environmental accruals for known contaminations of $111$107 million were included in the recorded carrying amount for indemnifications. These accruals were primarily included in the “Asset retirement obligations and accrued environmental costs” line on our consolidated balance sheet. For additional information about environmental liabilities, see Note 11—Contingencies and Commitments.

Indemnification and Release Agreement
In 2012, in connection with our separation from ConocoPhillips (the Separation), we entered into the 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.


Note 11—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 less than certain.


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 all 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 U.S. Environmental Protection Agency (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 at 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 JuneSeptember 30, 2018, our total environmental accrual was $465$456 million, compared with $458 million at December 31, 2017. 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 JuneSeptember 30, 2018, we had performance obligations secured by letters of credit and bank guarantees of $729$628 million related to various purchase and other commitments incident to the ordinary conduct of business.


Note 12—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 income. Gains and losses from derivative contracts held for trading not directly related to our physical business are reported net in the “Other income” line on our consolidated statement of income. 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 products, NGL, natural gas 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 13—Fair Value Measurements.

Commodity Derivative Contracts—We sell into or receive supply from the worldwide crude oil, refined petroleum products, NGL, natural gas 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, immaterial 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 right of setoff exists.

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 non-derivative positions such as inventory volumes. Financial derivative contracts may also offset physical derivative contracts, such as forward sales contracts. The percentage of our derivative contract volumes expiring within the next 12 months was at least 98 percent at JuneSeptember 30, 2018, and December 31, 2017.

Interest Rate Derivative Contracts—In 2016, we entered into interest rate swaps to hedge the variability of lease payments on our new headquarters. These monthly lease payments vary based on monthly changes in the one-month LIBOR and changes, if any, in our credit rating over the five-year term of the lease. The pay-fixed, receive-floating interest rate swaps have an aggregate notional value of $650 million and end in April 2021. We have designated these swaps as cash-flow hedges.

The aggregate net fair value of these swaps, which is included in the “Prepaid expenses and other current assets” and “Other assets” lines on our consolidated balance sheet, totaled $22$24 million and $14 million at JuneSeptember 30, 2018, and December 31, 2017, respectively.

We report the mark-to-market gains or losses on our interest rate swaps designated as highly effective cash-flow hedges as a component of other comprehensive income (loss), and reclassify such gains and losses into earnings in the same period during which the hedged transaction affects earnings. Net realized gains and losses from settlements of the swaps were immaterial for the three and sixnine months ended JuneSeptember 30, 2018 and 2017.

We currently estimate that pre-tax gains of $6$8 million will be reclassified from accumulated other comprehensive loss into general and administrative expenses during the next twelve months as the hedged transactions settle; however, the actual amounts that will be reclassified will vary based on changes in interest rates.

Credit Risk
Financial instruments potentially exposed to concentrations of credit risk consist primarily of over-the-counter (OTC) derivative contracts and trade receivables.

The credit risk from our OTC 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 until settled. However, we are exposed to the credit risk of those exchange brokers for receivables arising from daily margin cash calls, as well as for cash deposited to meet initial margin requirements.

Our trade receivables result primarily from the sale of products from, or related to, our refinery operations and reflect a broad national and international customer base, which limits our exposure to concentrations of credit risk. The majority of these receivables have payment terms of 30 days or less.less. We continually monitor this exposure and the creditworthiness of the counterparties and recognize bad debt expense based on historical write-off experience or specific counterparty collectability. Generally, we do not require collateral to limit the exposure to loss; however, we will sometimes use letters of credit, prepayments or master netting arrangements to mitigate credit risk with counterparties that both buy from and sell to us, as these agreements permit the amounts owed by us or owed to others to be offset against amounts due to us.


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 JuneSeptember 30, 2018, and December 31, 2017.


Note 13—Fair Value Measurements

Recurring Fair Value Measurements
We carry certain assets and liabilities at fair value, which we measure at the reporting date using an exit price (i.e., the price that would be received to sell an asset or paid to transfer a liability), 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. For the sixnine months ended JuneSeptember 30, 2018, derivative assets with an aggregate value of $81$244 million and derivative liabilities with an aggregate value of $83$244 million were transferred to Level 1 from Level 2, as measured from the beginning of the reporting period. The measurements were reclassified within the fair value hierarchy due to the availability of unadjusted quoted prices from an active market.

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 non-exchange quotes, we classify those contracts as Level 2.
OTC financial swaps and physicalPhysical commodity forward purchase and sales contracts 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, OTC swaps and physical commodity purchase and sales contracts 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. Financial OTC and physicalPhysical 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 mid-market pricing convention (the mid-point 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 observed market valuations for interest rate swaps that have notional values, 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.
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 material 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. These tables also show that our Level 3 activity was immaterial.

We have master netting agreements for all of our exchange-cleared derivative instruments the majorityand certain of our OTC derivative instruments and certain physical commodity forward contracts (primarily pipeline crude oil deliveries). The following tables show the impact of these agreements in the column “Effect of Counterparty Netting.”

The carrying values and fair values by hierarchy of our material financial instruments and commodity forward contracts, either carried or disclosed at fair value, including any effects of netting derivative assets with liabilities and netting collateral due to right of setoff or master netting agreements, were:

* Included in the “Operating expenses” and “Selling, general and administrative expenses” lines on our consolidated statement of income.


During the sixnine months ended JuneSeptember 30, 2018, we contributed $17$133 million to our U.S. employee benefit plans and $18$26 million to our international employee benefit plans. We currently expect to make additional contributions of approximately $140$20 million to our U.S. employee benefit plans and $20$10 million to our international employee benefit plans during the remainder of 2018.

During 2018 and 2017, lump-sum benefit payments exceeded the sum of service and interest costs for our U.S. pension plans. As a result, we recognized a proportionate share of prior actuarial losses, or pension settlement expense, totaling $54 million and $76 million for the nine months ended September 30, 2018 and 2017, respectively.

Note 16—Treasury Stock

In February 2018, we entered into a Stock Purchase and Sale Agreement (Purchase Agreement) with Berkshire Hathaway Inc. and National Indemnity Company, a wholly owned subsidiary of Berkshire Hathaway, to repurchase 35 million shares of Phillips 66 common stock for an aggregate purchase price of $3,280 million. Pursuant to the Purchase Agreement, the purchase price per share of $93.725 was based on the volume-weighted-average price of our common stock on the New York Stock Exchange on February 13, 2018. The transaction closed in February 2018. We funded the repurchase with cash of $1,880 million and borrowings of $1,400 million under our commercial paper program. These borrowings were subsequently refinanced through a public offering of senior notes in March 2018. This specific share repurchase transaction was separately authorized by our Board of Directors and therefore does not impact previously announced authorizations to repurchase shares of Phillips 66 common stock under our share repurchase program, which total up to $12.0 billion. See Note 9—Debt, for additional information regarding our borrowing activity during the sixnine months ended JuneSeptember 30, 2018.


Note 17—Restricted Cash

At JuneSeptember 30, 2018, and December 31, 2017, the company did not have any restricted cash.

During the fourth quarter of 2017, the segment performance measure used by our chief executive officer to assess performance and allocate resources was changed from “net income attributable to Phillips 66” to “net income.”  This change reflects the recognition that management does not differentiate between those earnings attributable to Phillips 66 and those attributable to noncontrolling interests when making operating and resource allocation decisions impacting segment performance.  Prior period segment information has been recast to conform to the current presentation. Intersegment sales are at prices that we believe approximate market.

Note 20—Income Taxes

Our effective income tax ratesrate for the three and sixnine months ended JuneSeptember 30, 2018, were 23was 21 percent, compared with 32 percent and 22 percent, respectively, compared with 31 percent and 30 percent for the corresponding periods of 2017. The decrease was primarily attributable to the enactment of the U.S. Tax Cuts and Jobs Act (the Tax Act) in December 2017, which reduced the U.S. federal corporate income tax rate from 35 percent to 21 percent beginning January 1, 2018. The effective income tax rate variesrates in the 2018 periods did not vary from the U.S. federal statutory income tax rate of 21 percent primarily due toas the effect of state income tax expense andwas primarily offset by adjustments to the provisional income tax benefit related to the Tax Act, partially offset byand the impact oftax benefits associated with our foreign operations and income attributable to noncontrolling interests.

During the three and sixnine months ended JuneSeptember 30, 2018, adjustmentswe recorded income tax benefits of $49 million and $20 million, respectively, to adjust the provisional income tax benefit recorded in December 2017 from theupon enactment of the Tax Act totaled $19 million and $29 million, respectively.Act. The adjustments to date were primarily due to the revision of our estimated deferred income tax balances in conjunction with the filing of our 2017 income tax return and the issuance of additional guidance by the U.S. Internal Revenue Service related to the calculation of the one-time deemed repatriation tax on foreign-sourced earnings that were previously tax deferred.tax. We have not yet completed our accounting for the income tax effects of the Tax Act, butAct; however, we have made reasonable estimates of thosethe effects on our existing deferred income tax balances and the one-time deemed repatriation tax. The final financial statement impact of the Tax Act may differ from our previously recorded estimates, possibly materially, due to, among other things, changes in interpretations of the Tax Act, any legislative action to address questions that arise because of the Tax Act, and changes in accounting standards for income taxes or related interpretations in response to the Tax Act, or any updates or changes to estimates the company has utilized to calculate the provisional impacts. The U.S. Securities and Exchange Commission (SEC) has issued rules that allow for a measurement period of up to one year after the enactment date of the Tax Act to finalize the recording of the related income tax impacts.


Note 21—Phillips 66 Partners LP

In 2013, we formed Phillips 66 Partners, a publicly traded master limited partnership, to own, operate, develop and acquire primarily fee-based crude oil, refined petroleum products and NGL pipelines, terminals and other midstream assets. Headquartered in Houston, Texas, Phillips 66 Partners’ operations currently consist of crude oil, refined petroleum products and NGL transportation, processing, terminaling and storage assets.
 
We consolidate Phillips 66 Partners because we determined it is a VIE of which we are the primary beneficiary. As general partner of Phillips 66 Partners, we have the ability to control its financial interests, as well as the ability to direct the activities that most significantly impact its economic performance. As a result of this consolidation, the public common and perpetual convertible preferred unitholders’ ownership interests in Phillips 66 Partners are reflected as noncontrolling interests in our financial statements. At JuneSeptember 30, 2018, we owned a 5554 percent limited partner interest and a 2 percent general partner interest in Phillips 66 Partners, while the public owned a 4344 percent limited partner interest and 13.8 million perpetual convertible preferred units.

The most significant assets of Phillips 66 Partners that are available to settle only its obligations, along with its most significant liabilities for which its creditors do not have recourse to Phillips 66’s general credit, were:

2018 Financing Activities
Phillips 66 Partners’ initial $250 million continuous offering of common units, or at-the-market (ATM) program, was completed during the three months endedin June 30, 2018.  At that time, Phillips 66 Partners commenced issuing common units under its second $250 million ATM program. For the three and sixnine months ended JuneSeptember 30, 2018 and 2017, on a settlement-date basis, Phillips 66 Partners had issued an aggregate of 1,152,119 and 1,340,934 common units, respectively, under the ATM programs, which generated net proceeds of $58$114 million and $67$171 million, respectively.respectively, from common units issued under the ATM programs.

Note 22—New Accounting Standards

In February 2018, the FASB issued ASU No. 2018-02, “Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.” This ASU allows for the deferred income tax effects stranded in accumulated other comprehensive income (AOCI) resulting from the Tax Act enacted in December 2017 to be reclassed from AOCI to retained earnings. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted. We are currently evaluating the impact of this ASU on our consolidated financial statements.

In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” The new standard amends the impairment model to utilize an expected loss methodology in place of the currently used incurred loss methodology, which may result in earlier recognition of losses. Public business entities should apply the guidance in ASU No. 2016-13 for annual periods beginning after December 15, 2019, including interim periods within those annual periods. Early adoption will be permitted for annual periods beginning after December 15, 2018. We are currently evaluating the provisions of ASU No. 2016-13 and assessing the impact on our consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842).” The new standard establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months.  Leases will continue to be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement.  Similarly, lessors will be required to classify leases as sales-type, finance or operating, with classification affecting the pattern of income recognition.  Classification for both lessees and lessors will be based on an assessment of whether risks and rewards, as well as substantive control have been transferred through a lease contract.  Public business entities should apply the guidance in ASU No. 2016-02 for annual periods beginning after December 15, 2018, including interim periods within those annual periods. Early adoption is permitted. Entities are requiredWe plan to adopt the ASU using a modified retrospective approach, subject to certain optional practical expedients, and apply the provisions of ASU No. 2016-02 by recognizing a cumulative-effect adjustment to leasing arrangements existing at or entered into after the earliest comparative period presented in the financial statements.opening balance of retained earnings as of our adoption date of January 1, 2019. We are currently evaluating the provisions of ASU No. 2016-02 and assessing its impact on our consolidated financial statements. As part of our assessment to-date, we have formed an implementation team, selected a software package, and completed software design and configuration within a test environment. Furthermore, we have loaded a majority ofcontinue to load our lease population into the software and commenced bothtest the software andconfiguration, lease data testing.and system reports. We expect the adoption of ASU No. 2016-02 will materially gross up our consolidated balance sheet with the recognition of the ROU assets and operating lease liabilities.  The impact to our consolidated statements of income and cash flows is not expected to be material.  The new standard will also require additional disclosures for financing and operating leases.

During the secondthird quarter of 2018, the chemicals and plastics industry continuedhigh-density polyethylene chain margin contracted due to benefit from feedstock cost advantages associated with manufacturing ethylene in regions of the world with significant NGL production.  The price of crude oil is rising faster than NGLlower polyethylene prices and thus the petrochemicals industry continues to experience lower ethylene costs in regions of the world where ethylene manufacturing is based on NGL rather than crude oil-derived feedstocks.  In particular, companies withhigher feedstock costs. However, North American ethane-based crackers integrated through ethylene derivatives have benefitedcontinue to benefit from a feedstock price advantage associated with abundant domestic supply and have capturedcontinue to capture a higher polyethylene chain margin than crackers in most other regions of the world.

Our Refining segment results are driven by several factors, including refining margins, cost control, refinery throughput, feedstock costs, product yields and turnaround activity. Industry crack spread indicators, the difference between market prices for refined petroleum products and crude oil, are used to estimate refining margins. During the secondthird quarter of 2018, the U.S. 3:2:1 crack spread (three barrels of crude oil producing two barrels of gasoline and one barrel of diesel) increaseddecreased compared with the firstsecond quarter of 2018 primarily due to higherlower gasoline and distillate cracks caused by the start of the summer driving season.higher refinery utilization and inventory. Northwest Europe crack spreads on average increased in the secondthird quarter of 2018, compared with the firstsecond quarter of 2018 due to higher demand.strengthening Asian and West African markets.

Results for our Marketing and Specialties (M&S) segment depend largely on marketing fuel margins, lubricant margins, and other specialty product margins. While M&S margins are primarily driven by market factors, largely determined by the relationship between supply and demand, marketing fuel margins, in particular, are influenced by the trend in spot prices for refined petroleum products. Generally speaking, 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.


RESULTS OF OPERATIONS

Unless otherwise indicated, discussion of results for the three and sixnine months ended JuneSeptember 30, 2018, is based on a comparison with the corresponding periods of 2017.

Basis of Presentation

During the fourth quarter of 2017, the segment performance measure used by our chief executive officer to assess performance and allocate resources was changed from “net income attributable to Phillips 66” to “net income.”  Prior period segment information has been recast to conform to the current presentation.

Our earnings increased $789$669 million, or 14381 percent, in the secondthird quarter of 2018, mainly reflecting:

Higher realized refining and marketing margins.
ImprovedHigher earnings from equity affiliates in our Midstream and Chemicals segments.
LowerFavorable income taxestax impacts due to the reduction of the U.S. federal corporate income tax rate beginning January 1, 2018, as a result of the U.S. Tax Cuts and Jobs Act (the Tax Act) enacted in December 2017.

These increases were partially offset by:

Higher interest and debt expense.
Higher net income attributable to noncontrolling interests due to contributionsthe contribution of assets to Phillips 66 Partners LP (Phillips 66 Partners) in the fourth quarter of 2017.
Higher interest and debt expense.


Our earnings increased $778$1,447 million, or 7276 percent, in the six-monthnine-month period of 2018, mainly reflecting:

Higher realized refining margins.

These increases were partially offset by:

Absence of a $261 million after-tax gain from the consolidation of Merey Sweeny, L.P. (MSLP) in 2017.
Higher net income attributable to noncontrolling interests due to contributionsthe contribution of assets to Phillips 66 Partners in the fourth quarter of 2017.

Statement of Income Analysis

Sales and other operating revenues for the secondthird quarter and six-monthnine-month period of 2018 increased 2016 percent and 1213 percent, respectively, and purchased crude oil and products increased 4036 percent and 3032 percent, respectively, mainly due to higher prices for petroleum products, crude oil and NGL. The increases in sales and other operating revenues in both periods were partially offset by a change in the presentation of excise taxes on sales of petroleum products resulting from our adoption of Financial Accounting Standard Board (FASB) Accounting Standards Update (ASU) No. 2014-09, “Revenue from Contracts with Customers (Topic 606),” on January 1, 2018. As part of our adoption of this ASU, prospectively from January 1, 2018, our presentation of excise taxes on sales of petroleum products changed to a net basis from a gross basis. As a result, the “Sales and other operating revenues” and “Taxes other than income taxes” lines on our consolidated statement of income for the secondthird quarter and six-monthnine-month period of 2018 are not presented on a comparable basis to the corresponding prior year periods. See Note 2—Changes in Accounting Principles and Note 3—Sales and Other Operating Revenues, in the Notes to Consolidated Financial Statements, for further information on our adoption of this ASU and our presentation of excise taxes on sales of petroleum products, respectively.

Equity in earnings of affiliates increased 6147 percent and 4143 percent in the secondthird quarter and six-monthnine-month period of 2018, respectively. These increases were mainly due to improvedhigher equity earnings from WRB Refining LP (WRB), driven by higherimproved realized margins, as well as higher equity earnings from affiliates in our Midstream and Chemicals segments. See the “Segment Results” section for additional information.

Other income decreased $447$472 million in the six-monthnine-month period of 2018. We recognized a noncash, pre-tax gain of $423 million in February 2017 related to the consolidation of MSLP. See Note 5—Business Combinations, in the Notes to Consolidated Financial Statements, for additional information.

Taxes other than income taxes decreased 97 percent in both the secondthird quarter and six-monthnine-month period of 2018. The decrease was primarily attributable to the change in our presentation of excise taxes on sales of petroleum products resulting from our adoption of ASU No. 2014-09 on January 1, 2018. See the “Sales and other operating revenues” section above for further discussion.
 
Interest and debt expense increased 2612 percent and 2218 percent in the secondthird quarter and six-monthnine-month period of 2018, respectively. The increase was due to higher average debt principal balances reflectingfrom our issuance of senior notes totaling $1,500 million in March 2018 and Phillips 66 Partners’ issuance of senior notes totaling $650 million in October 2017, as well as lower capitalized interest.2017.

Income tax expense increased 61 percent and 12 percent$62 million in the second quarter and six-monthnine-month period of 2018 respectively, primarily due to higher income before income taxes. These increases weretaxes, partially offset by the reduction of the U.S. federal corporate income tax rate from 35 percent to 21 percent beginning January 1, 2018, as a result of the Tax Act. See Note 20—Income Taxes, in the Notes to Consolidated Financial Statements, for information regarding our income tax expense and effective income tax rates.

Net income attributable to noncontrolling interests increased $34$50 million and $67$117 million in the secondthird quarter and six-monthnine-month period of 2018, respectively, reflectingdue to the contribution of assets to Phillips 66 Partners in 2017.

The Midstream segment provides crude oil and refined petroleum products transportation, terminaling and processing services, as well as natural gas, NGL and liquefied petroleum gas (LPG) transportation, storage, processing and marketing services, mainly in the United States. This segment includes our master limited partnership (MLP), Phillips 66 Partners, as well as our 50 percent equity investment in DCP Midstream, which includes the operations of its MLP, DCP Midstream, LP (DCP Partners).

Net income from the Midstream segment increased $106$123 million in the secondthird quarter of 2018 and $227$350 million in the six-monthnine-month period of 2018.

Net income from our Transportation business increased $63$56 million in the secondthird quarter of 2018 and $121$177 million in the six-monthnine-month period of 2018. The increased results in both periods were mainly driven by higher equity earnings from affiliates, including our joint ventures that own the Bakken Pipeline, which commenced commercial operations in June 2017,volumes, tariffs and increased revenue volumesstorage rates from our portfolio of consolidated and joint venture assets.

Net income from our NGL and Other business increased $41$46 million in the secondthird quarter of 2018 and $97$143 million in the six-monthnine-month period of 2018. The increasesincreased results in both periods were mainly due to higher volumes and equity earnings from affiliates, as well as the contribution of MSLP to Phillips 66 Partners in October 2017.2017, improved realized margins and volumes, and higher equity earnings from affiliates, partially offset by a contingency accrual recorded in the third quarter of 2018.


Net income from our investment in DCP Midstream increased $2$21 million in the secondthird quarter of 2018 and $9$30 million in the six-monthnine-month period of 2018. The increasesincreased results in both periods were mainly due to the timing of incentive distribution income allocations from DCP Partners and higher equity earnings from DCP Midstream’s affiliates and favorable impactsaffiliates. Additionally, results for the third quarter of the new U.S. federal corporate income tax rate beginning January 1, 2018, partially offset by unfavorable hedging results.2017 reflected higher asset impairment charges.

The Chemicals segment consists of our 50 percent 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 segments: Olefins and Polyolefins (O&P) and Specialties, Aromatics and Styrenics (SA&S).

Net income from the Chemicals segment increased $66$89 million in the secondthird quarter of 2018 and $117$206 million in the six-monthnine-month period of 2018. The increasesincreased results in both periods reflectreflected the commencement of full operations at itsCPChem’s new U.S. Gulf Coast petrochemicals assets in the second quarter of 2018, which resulted in higher production and sales volumes of polyethylene and ethylene, partially offset by lower capitalized interest. Additionally, higher equity earnings from CPChem’s affiliates,lower hurricane-related costs and thedowntime in 2018, and favorable impacts of the newlower U.S. federal corporate income tax rate beginning January 1, 2018, contributed to the increasesincreased results in both periods. Further, the nine-month period of 2018 reflected higher equity earnings from CPChem’s affiliates due to increased volumes and margins and the absence of an impairment charge recorded in 2017.

The Refining segment refines crude oil and other feedstocks into petroleum products (such as gasoline, distillates and aviation fuels) at 13 refineries in the United States and Europe.

Net income for the Refining segment increased $686$386 million in the secondthird quarter of 2018 and $518$904 million in the six-monthnine-month period of 2018. The increasesincreased results in both periods were primarily due to higher realized refining margins mainly driven by improved market crack spreads, configuration benefits and higher feedstock advantage, as well as lower turnaround costs.margins. Additionally, results for the six-monthnine-month period of 2017 reflectreflected an after-tax gain of $261 million recognized on the consolidation of MSLP in February 2017.

The increased realized refining margins for the third quarter and nine-month period of 2018 were primarily driven by higher feedstock advantage, clean product differentials and secondary product margins, as well as lower renewable identification number (RIN) costs, partially offset by a decline in market crack spreads.

See the “Business Environment and Executive Overview” section for information on market factors impacting this quarter’s results.

Our worldwide refining crude oil capacity utilization rate was 100 percent and 94decreased to 93 percent in the secondthird quarter and six-month period of 2018 respectively, compared with 98 percent and 91 percent in the secondthird quarter and six-month period of 2017 respectively. These increases were primarily attributabledue to lower planned maintenance and turnaround activity, and improved market conditions in 2018 as compared with 2017. These increases were partially offset by higher unplanned downtime. Our worldwide refining crude oil capacity utilization rate for the nine-month period of 2018 and 2017 was 94 percent.


Non-GAAP Reconciliations

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) purchase costs of feedstocks, primarily crude oil, used to produce the petroleum products. The 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 “Business Environment,” industry crack spreads measure the difference between market prices for refined petroleum products and crude oil. 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 margins.

Under generally accepted accounting principles in the United States (GAAP), the performance measure most directly comparable to refining margin per barrel is the Refining segment’s “net income per barrel.” 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 net income, such as general and administrative expenses and income taxes. It also includes our proportional share of joint venture refineries’ realized margins and excludes special items. Because refining realized 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 net income to realized refining margins:

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), as well as power generation operations.

The M&S segment net income increased $23$110 million in the secondthird quarter of 2018 and $66$176 million in the six-monthnine-month period of 2018. The increasesincreased results in both periods were primarily due to favorable impacts of the lower U.S. federal corporate income tax rate beginning January 1, 2018, and benefits from the retroactive extension of the 2017 biodiesel blender’s tax incentive in early 2018. Additionally, results for the third quarter of 2018 favorable impacts of the new U.S. federal corporate income tax rate beginning January 1, 2018, andbenefited from higher margins for specialty products and services. These increases were partially offset by lower U.S.international realized marketing margins.

See the “Business Environment and Executive Overview” section for information on marketing fuel margins and other market factors impacting this quarter’s results.

Non-GAAP Reconciliations

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) purchase costs of those fuels. These margins are converted to a per-barrel basis by dividing them by sales volumes measured on a barrel basis. MarketingRealized 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 marketing fuel margin per barrel is the marketing business’ “net income per barrel.” MarketingRealized 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 net income, such as general and administrative expenses and income taxes. 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 net income to realized marketing fuel margins:

Net interest consists of interest and financing expense, net of interest income and capitalized interest. Net interest increased in the secondthird quarter and six-monthnine-month period of 2018, mainly due to higher average debt principal balances reflectingfrom our issuance of senior notes totaling $1,500 million in March 2018 and Phillips 66 Partners’ issuance of senior notes totaling $650 million in October 2017; lower capitalized interest;2017, and impacts of the new U.S. federal corporate income tax rate beginning January 1, 2018.

Corporate general and administrative expenses increased in the third quarter and nine-month period of 2018, primarily due to impacts of the new U.S. federal corporate income tax rate beginning January 1, 2018, and higher employee-related costs.

During the secondthird quarter and six-monthnine-month period of 2018, Corporate and Other also includes one-time impactsincluded benefits related to the enactment of the Tax Act in December 2017, totaling $24$49 million and $17$32 million, respectively. These one-timeThe impacts related to the Tax Act are comprised of adjustments to the provisional deemed repatriation income tax expense and deferred income tax revaluation benefit recorded in December 2017, income tax benefits recorded by equity affiliates, as well asand other indirect income tax effects of the Tax Act.

The category “Other” includes certain income tax expenses, 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. The decrease in other costs in the third quarter and nine-month period of 2018 was primarily attributable to lower environmental-related accruals, partially offset by unfavorable tax impacts.

To meet our short- and long-term liquidity requirements, we look to a variety of funding sources but rely primarily on cash generated from operating activities. Additionally, Phillips 66 Partners has the ability to fund its growth activities through debt and equity offerings. During the first sixnine months of 2018, we generated $2.9$3.4 billion in cash from operations and raised net proceeds of $1.5 billion from the issuance of senior notes. Available cash was primarily used for repurchases of our common stock of $3.7$4.1 billion; capital expenditures and investments of $866 million;$1.6 billion; dividend payments on our common stock of $699 million;$1.1 billion; and early repayment of term loans of $250 million. During the first sixnine months of 2018, cash and cash equivalents decreased by $1.2$2.2 billion to $1.9 billion.$924 million.

In addition to cash flows from operating activities, we rely on our commercial paper and credit facility programs, asset sales and our ability to issue securities using our shelf registration statement to support our short- and long-term liquidity requirements. We believe current cash and cash equivalents and cash generated by operations, together with access to external sources of funds as described below under “Significant Sources of Capital,” will be sufficient to meet our funding requirements in the near and long term, including our capital spending, dividend payments, defined benefit plan contributions, debt repayments and share repurchases.

Significant Sources of Capital

Operating Activities
During the first sixnine months of 2018, cash generated by operating activities was $2,852$3,434 million, compared with $1,316$1,717 million for the first sixnine months of 2017. The increase in the first sixnine months of 2018, compared with the same period in 2017, reflectsreflected higher realized refining margins and distributions from our equity affiliates, as well as lower employee benefit plan contributions. These increases were partially offset by net favorableunfavorable working capital changes primarily driven by the effects of increasedhigher commodity prices, inventory impacts and the timing of payments and collections.

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 impacts 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 Affiliates
Our operating cash flows are also impacted by distribution decisions made by our equity affiliates, including DCP Midstream, CPChem and WRB. During the first sixnine months of 2018, cash from operations included distributions of $1,153$2,057 million from our equity affiliates, compared with $575$814 million during the same period of 2017. CPChem resumed distributions to us in the first quarter of 2018 following the return to full operations of its Cedar Bayou facility post-Hurricane Harvey and the start-up of its new U.S. Gulf Coast petrochemicals assets. We cannot control the amount of future dividends from equity affiliates; therefore, future dividend payments by these companies are not assured.

Phillips 66 Partners LP
Phillips 66 Partners’ initial $250 million continuous offering of common units, or at-the-market (ATM) program, was completed during the three months endedin June 30, 2018.  At that time, Phillips 66 Partners commenced issuing common units under its second $250 million ATM program. For the sixnine months ended JuneSeptember 30, 2018, on a settlement-date basis, Phillips 66 Partners had issued an aggregate of 1,340,934 common units under the ATM programs, which generated net proceeds of $67 million.$114 million from common units issued under the ATM programs. Since inception through JuneSeptember 30, 2018, Phillips 66 Partners had issued an aggregate of 5,059,802 common units under the ATM programs which generated net proceeds of $259$306 million.

Debt Issuances
In March 2018, Phillips 66 closed on a public offering of $1,500 million aggregate principal amount of unsecured notes consisting of:

$500 million of floating-rate Senior Notes due 2021. Interest on these notes is equal to the three-month London Interbank Offered Rate (LIBOR) plus 0.60% per annum and is payable quarterly in arrears on February 26, May 26, August 26 and November 26, beginning on May 29, 2018.

$800 million of 3.900% Senior Notes due 2028. Interest on these notes is payable semiannually on March 15 and September 15 of each year, beginning on September 15, 2018.

An additional $200 million of our 4.875% Senior Notes due 2044. Interest on these notes is payable semiannually on May 15 and November 15 of each year, beginning on May 15, 2018.
 
These notes are guaranteed by Phillips 66 Company, a wholly owned subsidiary. Phillips 66 used the net proceeds from the issuance of these notes to repay commercial paper borrowings during the first quarter of 2018, and for general corporate purposes.

Credit Facilities and Commercial Paper
At JuneSeptember 30, 2018, no amount had been directly drawn under our $5.0 billion revolving credit facility or our $5.0 billion commercial paper program supported by our revolving credit facility. In addition, at JuneSeptember 30, 2018, Phillips 66 Partners had no borrowings outstanding under its $750 million revolving credit facility. As a result, we had approximately $5.8 billion of total committed capacity available under our credit facilities at JuneSeptember 30, 2018.

Shelf Registration
We have a universal shelf registration statement on file with the U.S. Securities and Exchange Commission (SEC) under which we, as a well-known seasoned issuer, have the ability to issue and sell an indeterminate amount of various types of debt and equity securities.


Off-Balance Sheet Arrangements

Under the operating lease agreement on our headquarters facility in Houston, Texas, we have a residual value guarantee with a maximum future exposure of $554 million. The operating lease term ends in June 2021 and provides us the option, at the end of the lease term, to request to renew the lease, purchase the facility or assist the lessor in marketing it for resale.

We also have residual value guarantees associated with railcar and airplane leases with maximum future exposures totaling $291$319 million, which have remaining terms of up to five years. For one of our railcar leases, we estimated a total residual value deficiency of $56 million based on third-party appraisals of the railcars’ expected fair value at the end of theirthe lease term in May 2019. The total residual value deficiency is our estimate of the amount we will owe to the lessor at the end of the lease term and is recognized as expense over the remaining lease term. At JuneSeptember 30, 2018, the remaining unrecognized residual value deficiency was $24$17 million. 

In addition, we have guarantees outstanding related to certain joint venture debt obligations, which have remaining terms of up to seven years. The maximum potential amount of future payments to third parties under these guarantees was approximately $256$239 million.

See Note 10—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 JuneSeptember 30, 2018, and December 31, 2017, was $11,364$11,337 million and $10,110 million, respectively. Our total debt-to-capital ratio was 31 percent and 27 percent at JuneSeptember 30, 2018, and December 31, 2017, respectively.

In June 2018, Phillips 66 repaid $250 million of the $450 million outstanding under its three-year term loan facility due 2020.

Dividends
On May 9,July 11, 2018, our Board of Directors declared a quarterly cash dividend of $0.80 per common share. TheThis dividend was paid June 1,on September 4, 2018, to shareholders of record at the close of business on MayAugust 21, 2018. On July 11,October 5, 2018, our Board of Directors declared a quarterly cash dividend of $0.80 per common share. This dividend is payable on September 4,December 3, 2018, to shareholders of record at the close of business on August 21,November 19, 2018.

Share Repurchases
Our Board of Directors, at various times, has authorized repurchases of our outstanding common stock under our share repurchase program, which aggregate to a total authorization of up to $12.0 billion. The share repurchases have been, and are expected to be, funded primarily through available cash. The shares will be repurchased from time to time in the open market at our discretion, subject to market conditions and other factors, and in accordance with applicable regulatory requirements. We are not obligated to acquire any particular amount of common stock and may commence, suspend or discontinue purchases at any time or from time to time without prior notice. During the sixnine months ended JuneSeptember 30, 2018, we repurchased 4,387,2557,888,097 shares at a cost of $463$868 million under our share repurchase program. Since the inception of our share repurchase program in 2012 through JuneSeptember 30, 2018, we have repurchased a total of 128,529,785132,030,627 shares at a cost of $9,491$9,896 million. Shares of stock repurchased are held as treasury shares.

In February 2018, we entered into a Stock Purchase and Sale Agreement (Purchase Agreement) with Berkshire Hathaway Inc. and National Indemnity Company, a wholly owned subsidiary of Berkshire Hathaway, to repurchase 35 million shares of Phillips 66 common stock for an aggregate purchase price of $3,280 million. Pursuant to the Purchase Agreement, the purchase price per share of $93.725 was based on the volume-weighted-average price of our common stock on the New York Stock ExchangeNYSE on February 13, 2018. The transaction closed in February 2018. We funded the repurchase with cash of $1,880 million and borrowings of $1,400 million under our commercial paper program. These borrowings were subsequently refinanced through a public offering of senior notes. This specific share repurchase transaction was separately authorized by our Board of Directors and therefore does not impact previously announced authorizations under our share repurchase program, which are discussed above.

Employee Benefit Plan Contributions
During the nine months ended September 30, 2018, we contributed $133 million to our U.S. employee benefit plans and $26 million to our international employee benefit plans. We currently expect to make additional contributions of approximately $20 million to our U.S. employee benefit plans and $10 million to our international employee benefit plans during the remainder of 2018.

Railcar and Airplane Lease Residual Value Guarantees
For one of our railcar leases, we estimated a total residual value deficiency of $56 million based on a third-party appraisal of the railcars’ expected fair value at the end of theirthe lease term. The total residual value deficiency is our estimate of the amount we will owe to the lessor at the end of the lease term in May 2019. Due to current market uncertainties, changes in the estimated fair values of railcars could occur, which could increase or decrease our currently estimated residual value deficiency.

At JuneSeptember 30, 2018, our maximum future exposure for residual value guarantees under railcar and airplane lease arrangements was approximately $291$319 million. For additional information, see Note 10—Guarantees, in the Notes to Consolidated Financial Statements.

Midstream
During the first sixnine months of 2018, capital spending in our Midstream segment included continued development of additional Gulf Coast fractionation capacity, construction activities related to increasing storage capacity at our crude oil and refined petroleum products terminal located near Beaumont, Texas, and spending associated with return, reliability and maintenance projects in our Transportation and NGL businesses.  Phillips 66 Partners advanced several major construction projects, including progressing construction on the eastern leg of its 40-percent-owned Bayou Bridge joint venture pipeline, expansion activities on its 33-percent-owned DCP Sand Hills joint venture pipeline, constructing a new isomerization unit at the Lake Charles Refinery, and continued development of the Gray Oak Pipeline joint venture and related ventures.

In April 2018, Phillips 66 Partners announced that it received sufficient binding commitments to proceed with construction ofis constructing the Gray Oak Pipeline. The pipelinePipeline, which will provide crude oil transportation from the Permian Basin and Eagle Ford to destinations in the Corpus Christi and Sweeny/Freeport markets on the Texas Gulf Coast, including the Sweeny Refinery. In July 2018, Phillips 66 Partners completed the expansion open season to determine the scope andThe planned capacity of the pipeline system. The pipeline will have an initial capacity of 800,000has been expanded to 900,000 barrels per day (BPD) based on shipper commitments of 700,000 BPD and the reservation of capacity for walk-up shippers.  The pipeline is expandable to approximately 1 million BPD subject to additional shipper commitments. Phillips 66 Partners currently owns a 75 percent interest in the pipeline system, and other third parties have options to acquire up to a 32.75 percent interest. If all options are exercised, Phillips 66 Partners would own 42.25 percent.. The pipeline is expected to be in service by the end of 2019, with total cost of approximately $2$2.2 billion on a 100 percent basis. Phillips 66 Partners currently has a 75 percent ownership interest in the pipeline project, and third parties have options to acquire up to a 32.75 percent interest by year end. If all options are exercised, Phillips 66 Partners would own 42.25 percent.

In Corpus Christi, Texas, the Gray Oak Pipeline will connect to the new South Texas Gateway Terminal under development by Buckeye Partners, L.P. The marine terminal will have an initial storage capacity of 3.4 million barrels and is expected to begin operations by the end of 2019. Phillips 66 Partners owns a 25 percent interest in the joint venture that is constructing the terminal.

In June 2018, we announced the expansion ofAt the Sweeny Hub, which is an integrated NGL fractionation, storage and export complex strategically located on the Texas Gulf Coast with access to petrochemicals, fuels and liquefied petroleum gas (LPG) export markets. The expansion includeswe are constructing two 150,000-BPD NGL fractionators and associated pipeline infrastructure, and Phillips 66 Partners is adding 6 million barrels of additional storage capacity at Phillips 66 Partners’ Clemens Caverns. DCP Midstream has committed to supply Y-grade NGL feedstock and has an option to acquire up to a 30 percent ownership interest in the fractionators. Upon completion of the expansion, expected in late 2020, the Sweeny Hub will have 400,000 BPD of NGL fractionation capability and access to 15 million barrels of storage capacity.

During the first sixnine months of 2018, DCP Midstream had a self-funded capital program, and thus had no new capital infusions from us or our co-venturer. During this period, on a 100 percent basis, DCP Midstream’s capital expenditures and investments were approximately $385$684 million, which were primarily for expansion capital expenditures, including construction of the Mewbourn 3 and O’Connor 2 plants, and investments in the DCP Sand Hills and Gulf Coast Express joint venture pipelines, as well as maintenance capital expenditures for existing assets. We expect DCP to continue self-funding its capital program for the remainder of 2018.

In July 2018, Rockies Express Pipeline LLC (REX) repaid $550 million of its debt, reducing its total debt to approximately $2.0$2.1 billion.  REX funded the repayment through member cash contributions.  Our 25 percent share was approximately $138 million which weand was contributed to REX in July 2018.

Chemicals
During the first sixnine months of 2018, CPChem had a self-funded capital program, and thus required no new capital infusions from us or our co-venturer. During this period, on a 100 percent basis, CPChem’s capital expenditures and investments were $448$567 million, which were primarily for completion of its U.S. Gulf Coast Petrochemicals Project. We expect CPChem to continue self-funding its capital program for the remainder of 2018.

Refining
Capital spending for the Refining segment during the first sixnine months of 2018 was primarily for air emission reduction projects to meet new environmental standards, refinery upgrade projects to increase accessibility of advantaged crudes and improve product yields, improvements to the operating integrity of key processing units and safety-related projects.

Major construction activities included:
Installation of facilities to comply with U.S. Environmental Protection Agency (EPA) Tier 3 gasoline regulations at the Bayway and Ferndale refineries.
Installation of facilities to improve processing of advantaged crudes at the Lake Charles Refinery.
Installation of facilities to improve clean product yield at the Bayway Refinery, as well as the jointly owned Wood River Refinery.




Additionally, a project was approved at the Sweeny Refinery to optimize a fluid catalytic cracking unit to increase production of higher-value petrochemical products and higher-octane gasoline. The project is anticipated to be completed in mid-2020.

Generally, our equity affiliates in the Refining segment are intended to have self-funding capital programs.

Marketing and Specialties
Capital spending for the M&S segment during the first sixnine months of 2018 was primarily for reliability and maintenance projects and developing ourdevelopment of new international sites.

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 less than certain.

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 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. 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.

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 of these international and federal environmental laws and regulations, see the “Environmental” section in Management’s Discussion and Analysis of Financial Condition and Results of Operations in our 2017 Annual Report on Form 10-K.

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. As of December 31, 2017, we reported that we had been notified of potential liability under

CERCLA and comparable state laws at 31 sites within the United States. During the first sixnine months of 2018, there waswe were notified of one new site, for which we received notification of potential liability, twoone previously resolved site was returned to active status, four sites were deemed resolved and closed, and one site wastwo sites were deemed resolved but not closed, leaving 2927 unresolved sites with potential liability at JuneSeptember 30, 2018.

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 material costs and liabilities will not be incurred. 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.

Climate Change
There has been a broad range of proposed or promulgated state, national and international laws focusing on greenhouse gas (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 review items, 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 2017 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.


NEW ACCOUNTING STANDARDS

In February 2018, the FASB issued ASU No. 2018-02, “Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.” This ASU allows for the deferred income tax effects stranded in accumulated other comprehensive income (AOCI) resulting from the Tax Act enacted in December 2017 to be reclassed from AOCI to retained earnings. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted. We are currently evaluating the impact of this ASU on our consolidated financial statements.

In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” The new standard amends the impairment model to utilize an expected loss methodology in place of the currently used incurred loss methodology, which may result in earlier recognition of losses. Public business entities should apply the guidance in ASU No. 2016-13 for annual periods beginning after December 15, 2019, including interim periods within those annual periods. Early adoption will be permitted for annual periods beginning after December 15, 2018. We are currently evaluating the provisions of ASU No. 2016-13 and assessing the impact on our consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842).” The new standard establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months.  Leases will continue to be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement.  Similarly, lessors will be required to classify leases as sales-type, finance or operating, with classification affecting the pattern of income recognition.  Classification for both lessees and lessors will be based on an assessment of whether risks and rewards, as well as substantive control have been transferred through a lease contract.  Public business entities should apply the guidance in ASU No. 2016-02 for annual periods beginning after December 15, 2018, including interim periods within those annual periods. Early adoption is permitted. Entities are requiredWe plan to adopt the ASU using a modified retrospective approach, subject to certain optional practical expedients, and apply the provisions of ASU No. 2016-02 by recognizing a cumulative-effect adjustment to leasing arrangements existing at or entered into after the earliest comparative period presented in the financial statements.opening balance of retained earnings as of our adoption date of January 1, 2019. We are currently evaluating the provisions of ASU No. 2016-02 and assessing its impact on our consolidated financial statements. As part of our assessment to-date, we have formed an implementation team, selected a software package, and completed software design and configuration within a test environment. Furthermore, we have loaded a majority ofcontinue to load our lease population into the software and commenced bothtest the software andconfiguration, lease data testing.and system reports. We expect the adoption of ASU No. 2016-02 will materially gross up our consolidated balance sheet with the recognition of the ROU assets and operating lease liabilities.  The impact to our consolidated statements of income and cash flows is not expected to be material.  The new standard will also require additional disclosures for financing and operating leases.

PART II. OTHER INFORMATION

Item 1.   LEGAL PROCEEDINGS

The following is a description of reportable legal proceedings, including those involving governmental authorities under federal, state and local laws regulating the discharge of materials into the environment, for this reporting period. There were nowas one new mattersmatter that arose during the secondthird quarter of 2018. There were material developments that occurred with respect to one mattertwo matters previously reported in our 2017 Annual Report on Form 10-K or our Quarterly ReportReports on Form 10-Q for the quarterly periodperiods ended March 31, 2018, and June 30, 2018. While it is not possible to accurately predict the final outcome of reported, pending proceedings, if any one or more of such proceedings were decided adversely to Phillips 66, we expect there would be no material effect on our consolidated financial position. Nevertheless, such proceedings are reported pursuant to U.S. Securities and Exchange Commission (SEC) regulations.

Our U.S. refineries are implementing two separate consent decrees, regarding alleged violations of the Federal Clean Air Act, with the U.S. Environmental Protection Agency (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.

New MattersMatter
There are no new mattersIn September 2018, the South Coast Air Quality Management District (District) demanded penalties to report.resolve nine Notices of Violation (NOVs) issued in 2016 and 2017. The NOVs pertain to alleged violations of air permit requirements or other air pollution regulatory requirements at our Los Angeles Refinery and Colton Terminal. The aggregate amount demanded is $185,750. Phillips 66 is working with the District to resolve these NOVs.

Matters Previously Reported
In March 2018,July 2014, the EPA issued an NOV alleging flaring-related violations between 2009 and 2013 at the Wood River Refinery. In September 2014, the EPA issued an NOV alleging a violation of hazardous air pollution regulations at the Wood River Refinery during 2014. A settlement addressing both NOVs was filed in the U.S. District Court (S.D. Illinois) on August 10, 2018. This settlement is expected to be finalized in the fourth quarter of 2018. Pursuant to the settlement, Phillips 66 Partners received notification fromwill pay total penalties of $990,000 (of which $515,000 constitutes stipulated penalties pursuant to the Illinois Attorney General’s office of a proposed penalty arising from the April 2015 release of approximately 800 barrels of diesel fuel from its pipeline that transports products from a terminal in Hartford, Illinois, to a dock on the Mississippi River. This matter has been resolved with a penalty payment of $120,000.consent decrees described above) and $500,000 for lead abatement projects.
