Notes to Consolidated Financial Statements | Phillips 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 2015 Annual Report on Form 10-K. The results of operations for the three and six months ended June 30, 2016, are not necessarily indicative of the results to be expected for the full year.
Note 2—Changes in Accounting Principles
Effective January 1, 2016, we early adopted the Financial Accounting Standards Board (FASB) Accounting Standards Update (ASU) No. 2015-17, “Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes.” The new update simplified the presentation of deferred income taxes and required deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. The classification was made at the taxpaying component level of an entity, after reflecting any offset of deferred tax liabilities, deferred tax assets and any related valuation allowances. We applied this ASU prospectively to all deferred tax liabilities and assets.
In June 2014, the FASB issued ASU 2014-10, “Development Stage Entities (Topic 915): Elimination of Certain Financial Reporting Requirements, Including an Amendment to Variable Interest Entities (VIE) Guidance in Topic 810, Consolidation.” The new update removes the definition of a development stage entity from the Master Glossary of the Accounting Standard Codification (ASC) and the related financial reporting requirements specific to development stage entities. This ASU is intended to reduce cost and complexity of financial reporting for entities that have not commenced planned principal operations. For financial reporting requirements other than the VIE guidance in ASC Topic 810, “Consolidation,” ASU 2014-10 was effective for annual and quarterly reporting periods of public entities beginning after December 15, 2014. For the financial reporting requirements related to VIEs in ASC Topic 810, “Consolidation,” ASU 2014-10 was effective for annual and quarterly reporting periods of public entities beginning after December 15, 2015. We adopted the provisions of this ASU related to the financial reporting requirements other than the VIE guidance effective January 1, 2015. We adopted the remaining provisions effective January 1, 2016, and updated our disclosures about the risks and uncertainties related to our joint venture entities that have not commenced their principal operations.
Note 3—Variable Interest Entities
In 2013, we formed Phillips 66 Partners LP, a master limited partnership, to own, operate, develop and acquire primarily fee-based crude oil, refined petroleum product and natural gas liquids (NGL) pipelines and terminals, as well as other transportation and midstream assets. We consolidate Phillips 66 Partners as we determined that Phillips 66 Partners is a VIE and 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. See Note 19—Phillips 66 Partners LP, for additional information.
We hold variable interests in VIEs that have not been consolidated because we are not considered the primary beneficiary. Information on our significant non-consolidated VIEs follows.
Merey Sweeny, L.P. (MSLP) is a limited partnership that owns a delayed coker and related facilities at the Sweeny Refinery. As discussed more fully in Note 6—Investments, Loans and Long-Term Receivables, in August 2009, a call right was exercised to acquire the 50 percent ownership interest in MSLP of the co-venturer, Petróleos de Venezuela S.A. (PDVSA). That exercise was challenged, and the dispute has been arbitrated. Until all legal challenges are resolved, we will continue to use the equity method of accounting for MSLP, and the VIE analysis below is based on the ownership and governance structure in place prior to the exercise of the call right. MSLP is a VIE because, in securing lender consents in connection with our separation from ConocoPhillips in 2012 (the Separation), we provided a 100 percent debt
6

Table of Contents
guarantee to the lender of MSLP’s 8.85% senior notes (MSLP Senior Notes). PDVSA did not participate in the debt guarantee. In our VIE assessment, this disproportionate debt guarantee, plus other liquidity support provided jointly by us and PDVSA independently of equity ownership, results in MSLP not being exposed to all potential losses. We have determined we are not the primary beneficiary while our call exercise award is subject to being vacated, because under the partnership agreement, the co-venturers jointly direct the activities of MSLP that most significantly impact economic performance. At June 30, 2016, our maximum exposure to loss was the outstanding principal balance of the MSLP Senior Notes of $140 million and our investment in MSLP of $179 million.
We have a 25 percent ownership interest in Dakota Access, LLC (DAPL) and Energy Transfer Crude Oil Company, LLC (ETCOP), whose planned principal operations have not commenced. Until the planned principal operations have commenced, these entities do not have sufficient equity at risk to fully fund the construction of all assets required for principal operations, and thus represent VIEs. We have determined we are not the primary beneficiary because we and our co-venturer jointly direct the activities of DAPL and ETCOP that most significantly impact economic performance. We use the equity method of accounting for these investments. At June 30, 2016, our maximum exposure to loss represented the aggregate book value of our equity investments of $520 million and our loans of $107 million.
Note 4—Inventories
Inventories consisted of the following:

| Millions of Dollars
| June 30 2016 |  |  | December 31 2015 |
Crude oil and petroleum products | $ | 3,725 |  |  | 3,214 |
Materials and supplies | 268 |  |  | 263 |
| $ | 3,993 |  |  | 3,477 |

Inventories valued on the last-in, first-out (LIFO) basis totaled $3,600 million and $3,085 million at June 30, 2016, and December 31, 2015, respectively. The estimated excess of current replacement cost over LIFO cost of inventories amounted to approximately $3.0 billion and $1.3 billion at June 30, 2016, and December 31, 2015, respectively.
Certain planned year-to-date reductions in inventory caused liquidations of LIFO inventory values that are not expected to be replaced by the end of the year. These liquidations decreased net income by approximately $15 million and $58 million during the three- and six-month periods ending June 30, 2016, and $1 million and $37 million for the comparable periods of 2015.
Note 5—Assets Held for Sale or Sold
In July 2013, we completed the sale of the Immingham Combined Heat and Power Plant (ICHP), which was included in our Marketing and Specialties (M&S) segment. A gain on this disposal was deferred at the time of sale due to an indemnity provided to the buyer. We recognized the deferred gain in earnings as our exposure under the indemnity declined, beginning in the third quarter of 2014 and ending in the second quarter of 2015 when the indemnity expired. We recognized $132 million and $242 million of the deferred gain in the three-month and six-month periods ended June 30, 2015, respectively, and these amounts are included in the “Net gain on dispositions” line of our consolidated statement of income.

As of June 30, 2016, DAPL and ETCOP have borrowed $382 million and $46 million, respectively. Our 25 percent share of those loans was $95 million and $12 million, respectively. At June 30, 2016, the book values of our investments in DAPL and ETCOP were $391 million and $129 million, respectively.

MSLP owns a delayed coker and related facilities at the Sweeny Refinery. MSLP processes long residue, which is produced from heavy sour crude oil, for a processing fee. Fuel-grade petroleum coke is produced as a by-product and becomes the property of MSLP. Prior to August 28, 2009, MSLP was owned 50/50 by ConocoPhillips and PDVSA. Under the agreements that govern the relationships between the partners, certain defaults by PDVSA with respect to supply of crude oil to the Sweeny Refinery triggered the right to acquire PDVSA’s 50 percent ownership interest in MSLP, which was exercised on August 28, 2009. PDVSA initiated arbitration with the International Chamber of Commerce challenging the exercise of the call right and claiming it was invalid. The arbitral tribunal held hearings on the merits of the dispute in December 2012, and post-hearing briefs were exchanged in March 2013. The arbitral tribunal issued its ruling in April 2014, which upheld the exercise of the call right and the acquisition of the 50 percent ownership interest. In July 2014, PDVSA filed a petition in U.S. district court to vacate the tribunal’s ruling, and in September 2015, the petition was denied. In January 2016, PDVSA filed an appeal in the appellate court to vacate this ruling. Following the Separation, Phillips 66 generally indemnifies ConocoPhillips for liabilities, if any, arising out of the exercise of the call right or otherwise with respect to the joint venture or the refinery. Until all legal challenges are resolved, we will continue to use the equity method of accounting for our investment in MSLP.

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
At both June 30, 2016, and December 31, 2015, we had no direct outstanding borrowings under our $5 billion revolving credit agreement, while $51 million in letters of credit had been issued that were supported by it. At June 30, 2016, $40 million was outstanding under the $500 million revolving credit agreement of Phillips 66 Partners, compared with no borrowings outstanding under the facility at December 31, 2015. Accordingly, as of June 30, 2016, an aggregate $5.4 billion of total capacity was available under these facilities.
During the second quarter of 2016, we reclassified $1.5 billion of 2.95% Senior Notes due 2017 from long-term debt to short-term debt on our consolidated balance sheet, due to the maturity of the notes within the next twelve months.
Note 10—Guarantees
At June 30, 2016, we were liable for certain contingent obligations under various contractual arrangements as described below. We recognize a liability, at inception, 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 2012, in connection with the Separation, we issued a guarantee for 100 percent of the MSLP Senior Notes issued in July 1999. At June 30, 2016, the maximum potential amount of future payments to third parties under the guarantee was estimated to be $140 million, which could become payable if MSLP fails to meet its obligations under the senior notes agreement. The MSLP Senior Notes mature in 2019.
Other Guarantees
In June 2016, the operating lease commenced on our new headquarters facility in Houston, Texas, after construction was deemed substantially complete. Under this lease agreement, we have a residual value guarantee with a maximum future exposure of $554 million. The operating lease has a term of five years 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 have residual value guarantees associated with railcar and airplane leases with maximum future exposures totaling $376 million. We have other guarantees with maximum future exposures totaling $112 million, which consist primarily of guarantees to fund the short-term cash liquidity deficits of certain joint ventures and guarantees of the lease payment obligations of a joint venture. These guarantees generally extend up to eight years or the life of the venture.
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 qualifying indemnifications. Agreements associated with these sales include indemnifications for taxes, litigation, environmental liabilities, permits and licenses, and employee claims; and real estate indemnity against tenant defaults. The provisions of these indemnifications vary greatly. The majority of these indemnifications are related to environmental issues with generally indefinite terms, and the maximum amount of future payments is generally unlimited. The carrying amount recorded for indemnifications at June 30, 2016, was $193 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 the liability is 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. Included in the recorded carrying amount were $98 million of environmental accruals for known contamination that were primarily included in “Asset retirement obligations and accrued environmental costs” at June 30, 2016. For additional information about environmental liabilities, see Note 11—Contingencies and Commitments.

Indemnification and Release Agreement
In 2012, we entered into the Indemnification and Release Agreement with ConocoPhillips. 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 of those potentially responsible 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 and some of the indemnifications are subject to dollar and time limits.

Table of Contents
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 purchase 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 June 30, 2016, our total environmental accrual was $486 million, compared with $485 million at December 31, 2015. 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 June 30, 2016, we had performance obligations secured by letters of credit and bank guarantees of $481 million (of which $51 million was issued under the provisions of our revolving credit facility, and the remainder was issued as direct bank letters of credit and bank guarantees) 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 foreign currency exchange rates, interest rates and commodity prices or to capture market opportunities. Because we have not used cash-flow hedge accounting for commodity derivative contracts, all gains and losses, realized or unrealized, from these contracts have been recognized in the consolidated statement of income. Gains and losses from derivative contracts held for trading not directly related to our physical business, whether realized or unrealized, have been reported net in “Other income” on our consolidated statement of income. Cash flows from all our derivative activity for the periods presented appear in the operating section of the consolidated statement of cash flows.
Purchase and sales contracts with fixed minimum notional volumes for commodities that are readily convertible to cash (e.g., crude oil and gasoline) are recorded on the balance sheet as derivatives unless the contracts are eligible for, and we elect, the normal purchases and normal sales exception (i.e., contracts to purchase or sell quantities we expect to use or sell over a reasonable period in the normal course of business). We generally apply this normal purchases and normal sales exception to eligible crude oil, refined product, NGL, natural gas and power commodity purchase and sales contracts; however, we may elect not to apply this exception (e.g., when another derivative instrument will be used to mitigate the risk of the purchase or sales contract but hedge accounting will not be applied, in which case both the purchase or sales contract and the derivative contract mitigating the resulting risk will be recorded on the balance sheet at fair value). Our derivative instruments are held 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 products, natural gas, NGL, 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
12

Table of Contents
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 balance sheet line items that include the fair values of commodity derivative assets and liabilities presented net (i.e., commodity derivative assets and liabilities with the same counterparty are netted where the right of setoff exists); however, the balances in the following table are presented gross. For information on the impact of counterparty netting and collateral netting, see Note 13—Fair Value Measurements.

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 approximately 99 percent at both June 30, 2016 and December 31, 2015.

Table of Contents
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. 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, and 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 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 not material at June 30, 2016, or December 31, 2015.
Note 13—Fair Value Measurements
Fair Values of Financial Instruments
We used the following methods and assumptions to estimate the fair value of financial instruments:

• | Cash and cash equivalents: The carrying amount reported on the consolidated balance sheet approximates fair value.

• | Accounts and notes receivable: The carrying amount reported on the consolidated balance sheet approximates fair value.

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

• | Commodity swaps and forward purchases and sales: Fair value is estimated based on forward market prices and approximates the exit price at period end. 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.

• | Futures: Fair values are based on quoted market prices obtained from the New York Mercantile Exchange, the Intercontinental Exchange, or other traded exchanges.

• | Forward-exchange contracts: Fair value is estimated by comparing the contract rate to the forward rate in effect at the end of the reporting period, which approximates the exit price at that date.

14

Table of Contents
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 lowest level of input significant to its 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 six-month period ended June 30, 2016, derivative assets with an aggregate value of $151 million and derivative liabilities with an aggregate value of $117 million were transferred into 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.
Recurring Fair Value Measurements
Financial assets and liabilities recorded at fair value on a recurring basis consist primarily of investments to support nonqualified deferred compensation plans and derivative instruments. The deferred compensation investments are measured at fair value using unadjusted prices available from national securities exchanges; therefore, these assets are categorized as Level 1 in the fair value hierarchy. We value our exchange-traded commodity derivatives using closing prices provided by the exchange as of the balance sheet date, and these are also classified 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 physical commodity forward purchase and sales contracts are generally valued using 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. 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 physical 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.
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 gross (i.e., without the effect of netting where the legal right of setoff exists) in the hierarchy sections of these tables. These tables also show that our Level 3 activity was not material.
We have master netting agreements for all of our exchange-cleared derivative instruments, the majority of our OTC derivative instruments, and certain physical commodity forward contracts (primarily pipeline crude oil deliveries). The following tables show the fair value of these contracts on a net basis in the column “Effect of Counterparty Netting,” which is how these also appear on the consolidated balance sheet.

Note 18—Income Taxes
Our effective tax rates for the second quarter and the first six months of 2016 were 28 percent and 31 percent, respectively, compared with 30 percent and 29 percent for the corresponding periods of 2015.
The effective tax rate varies from the federal statutory tax rate of 35 percent primarily as a result of state tax expense, partially offset by the manufacturing deduction and foreign operations.
The decrease in the effective tax rate for the second quarter of 2016, compared with the second quarter of 2015, was primarily attributable to a favorable tax ruling in the United Kingdom and the relative impact of foreign earnings that are subject to a lower tax rate, partially offset by a decrease in the manufacturing deduction and recognition of a nontaxable gain in 2015 associated with the sale of ICHP.
The increase in the effective tax rate for the first six months of 2016, compared with the first six months of 2015, was primarily attributable to a decrease in the manufacturing deduction in the first six months of 2016 and recognition of a nontaxable gain in 2015 associated with the sale of ICHP, partially offset by the relative impact of foreign earnings that are subject to a lower tax rate. For additional information on the nontaxable gain, see Note 5—Assets Held for Sale or Sold.
Note 19—Phillips 66 Partners LP
In 2013, we formed Phillips 66 Partners, a master limited partnership, to own, operate, develop and acquire primarily fee-based crude oil, refined petroleum product and NGL pipelines and terminals, as well as other transportation and midstream assets.
In March 2016, we contributed to Phillips 66 Partners a 25 percent interest in our then wholly owned subsidiary, Phillips 66 Sweeny Frac LLC, which owns the Sweeny Fractionator One, an NGL fractionator located within our Sweeny Refinery complex in Old Ocean, Texas, and the Clemens Caverns, an NGL salt dome storage facility located near Brazoria, Texas. Total consideration for the transaction was $236 million, which consisted of Phillips 66 Partners’ assumption of a $212 million note payable to us and the issuance of common units and general partner units to us with an aggregate fair value of $24 million.
In May 2016, we contributed to Phillips 66 Partners the remaining 75 percent interest in Phillips 66 Sweeny Frac LLC and a 100 percent interest in our wholly owned subsidiary, Phillips 66 Plymouth LLC, which owns the Standish Pipeline, a refined petroleum product pipeline system extending from the Ponca City Refinery in Ponca City, Oklahoma, and terminating at the North Wichita Terminal in Wichita, Kansas. Total consideration for the transaction was $775 million, consisting of Phillips 66 Partners’ assumption of $675 million of notes payable to us and the issuance of common units and general units to us with an aggregate fair value of $100 million.
On May 10, 2016, Phillips 66 Partners completed a public offering of 12,650,000 common units representing limited partner interests, at a public offering price of $52.40 per unit. The net proceeds at closing were $656 million. Phillips 66 Partners used these net proceeds to repay a portion of the assumed notes discussed above.
In June 2016, Phillips 66 Partners began issuing common units under a continuous offering program, which allows for the issuance of up to an aggregate of $250 million of Phillips 66 Partners’ common units, in amounts, at prices and on terms to be determined by market conditions and other factors at the time of the offerings. We refer to this as an at-the-market, or ATM, program. During the three months ended June 30, 2016, on a settlement-date basis, Phillips 66 Partners issued an aggregate of 262,858 common units under the ATM program, generating net proceeds of approximately $14 million.
At June 30, 2016, we owned a 61 percent limited partner interest and a 2 percent general partner interest in Phillips 66 Partners, while the public owned a 37 percent limited partner interest. We consolidate Phillips 66 Partners because we control the partnership through our general partner interest (see Note 3—Variable Interest Entities, for additional information). The public’s ownership interest in Phillips 66 Partners is reflected as a noncontrolling interest in our

Table of Contents
financial statements. The most significant assets of Phillips 66 Partners that are available to settle only its obligations at June 30, 2016, were equity investments of $1,008 million and net PP&E of $1,673 million.
Note 20—New Accounting Standards
In June 2016, the FASB issued ASU 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 will result in the more timely recognition of losses. Public business entities should apply the guidance in ASU 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 2016-13 and assessing the impact on our financial statements.
In March 2016, the FASB issued ASU No. 2016-07, “Equity Method and Joint Ventures (Topic 323): Simplifying the Transition to the Equity Method of Accounting.” The new standard eliminates the requirement that an investor retroactively apply equity method accounting when an investment that it had accounted for by another method initially qualifies for the equity method. Public business entities should apply the guidance in ASU 2016-07 for annual periods beginning after December 15, 2016, including interim periods within those annual periods, with early adoption permitted. We are currently evaluating the provisions of ASU 2016-07, but do not expect any significant impact on our financial statements.
In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842).” In the new standard, the FASB modified its determination of whether a contract is a lease rather than whether a lease is a capital or operating lease under the previous accounting principles generally accepted in the United States (GAAP). A contract represents a lease if a transfer of control occurs over an identified property, plant and equipment for a period of time in exchange for consideration. Control over the use of the identified asset includes the right to obtain substantially all of the economic benefits from the use of the asset and the right to direct its use. The FASB continued to maintain two classifications of leases — financing and operating — which are substantially similar to capital and operating leases in the previous lease guidance. Under the new standard, recognition of assets and liabilities arising from operating leases will require recognition on the balance sheet. The effect of all leases in the statement of comprehensive income and the statement of cash flows will be largely unchanged. Lessor accounting will also be largely unchanged. Additional disclosures will be required for financing and operating leases for both lessors and lessees. Public business entities should apply the guidance in ASU 2016-02 for annual periods beginning after December 15, 2018, including interim periods within those annual periods. Early adoption is permitted. We are currently evaluating the provisions of ASU 2016-02 and assessing its impact on our financial statements.
In January 2016, the FASB issued ASU No. 2016-01, “Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities,” to meet its objective of providing more decision-useful information about financial instruments. The majority of this ASU’s provisions amend only the presentation or disclosures of financial instruments; however, one provision will also affect net income. Equity investments carried under the cost method or lower of cost or fair value method of accounting, in accordance with current GAAP, will have to be carried at fair value upon adoption of ASU 2016-01, 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. Public business entities should apply the guidance in ASU 2016-01 for annual periods beginning after December 15, 2017, and interim periods within those annual periods, with early adoption prohibited. We are currently evaluating the provisions of ASU 2016-01. Our initial review indicates that ASU 2016-01 will have a limited impact on our financial statements.
In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606).” The new standard converged guidance on recognizing revenues in contracts with customers under GAAP and International Financial Reporting Standards. This ASU is intended to improve comparability of revenue recognition practices across entities, industries, jurisdictions and capital markets. In August 2015, the FASB issued ASU 2015-14, “Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date.” The amendment in this ASU defers the effective date of ASU 2014-09 for all entities for one year. Public business entities should apply the guidance in ASU 2014-09 to
24

Table of Contents
annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Earlier adoption is permitted only as of annual reporting periods beginning after December 31, 2016, including interim reporting periods within that reporting period. Retrospective or modified retrospective application of the accounting standard is required. We are currently evaluating the provisions of ASU 2014-09 and assessing the impact on our financial statements. As part of our assessment work to-date, we have formed an implementation work team, completed training on the new ASU’s revenue recognition model and are continuing our contract review and documentation.

Business Environment
Commodity prices increased during the second quarter of 2016 compared with the first quarter of 2016; however, prices were still lower compared with the second quarter of 2015. Additionally, the discount for U.S. benchmark West Texas Intermediate (WTI) versus the international benchmark Brent narrowed over the course of 2015 and the first half of 2016 due to falling domestic production. The sustained low commodity price environment has had a variety of impacts, both favorable and unfavorable, on our downstream businesses that vary by segment.
Earnings in the Midstream segment, which includes our 50 percent equity investment in DCP Midstream, LLC (DCP Midstream), are closely linked to natural gas liquids (NGL) prices, natural gas prices and crude oil prices. NGL prices increased in the second quarter of 2016 compared with the first quarter of 2016 as crude oil prices increased. NGL production growth from liquids-rich shale plays continued to outpace domestic demand growth from the petrochemical industry, but exports continue to support prices and reduce inventories. Natural gas prices recovered throughout the second quarter of 2016 from the first quarter of 2016 as production flattened and demand for natural gas to fuel electricity generation increased. Though the average NGL prices and natural gas prices increased in the second quarter of 2016, prices were lower compared with the second quarter of 2015 due to large inventories.
The Chemicals segment consists of our 50 percent equity investment in Chevron Phillips Chemical Company LLC (CPChem). The chemicals and plastics industry is mainly a commodity-based industry where the margins for key products are based on supply and demand, as well as cost factors. The petrochemicals industry continues to experience lower ethylene cash costs in regions of the world where ethylene manufacturing is based upon NGL rather than crude-oil-derived feedstocks. In particular, companies with North American light NGL-based crackers have benefited from lower-priced feedstocks. The ethylene to polyethylene chain margins in the second quarter of 2016 improved slightly compared with the first quarter of 2016; however, the chain margins remained compressed in the second quarter of 2016 with lower crude oil prices compared with the second quarter of 2015.
The results of our Refining segment are driven by several factors including refining margins, cost control, refinery throughput and product yields. Refinery margins, often referred to as crack spreads, are measured as the difference between market prices for refined petroleum products and crude oil. The U.S. 3:2:1 crack spread (three barrels of crude oil producing two barrels of gasoline and one barrel of diesel) increased in the second quarter of 2016, compared with the first quarter of 2016, due to seasonally increasing demand for refined products. The U.S. crack spread was lower during the second quarter of 2016, compared with the second quarter of 2015, because of high product inventories resulting from high refinery utilization.
The Northwest Europe benchmark crack spread improved during the second quarter of 2016 compared with the first quarter of 2016. The increase was due to seasonally increasing demand for refined products. The crack spread decreased in the second quarter of 2016 compared with the second quarter of 2015 because of high product inventories resulting from high refinery utilization.
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 primarily determined by the trend of spot prices for refined 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 six-month periods ended June 30, 2016, is based on a comparison with the corresponding periods of 2015.
Consolidated Results
A summary of net income (loss) attributable to Phillips 66 by business segment follows:

| Millions of Dollars
| Three Months Ended June 30 |  | Six Months Ended June 30
| 2016 |  | 2015 |  |  | 2016 |  | 2015 |
Midstream | $ | 39 |  | (78 | ) |  | 104 |  | (11 | )
Chemicals | 190 |  | 295 |  |  | 346 |  | 498 |
Refining | 149 |  | 604 |  |  | 235 |  | 1,142 |
Marketing and Specialties | 229 |  | 314 |  |  | 434 |  | 618 |
Corporate and Other | (111 | ) | (123 | ) |  | (238 | ) | (248 | )
Net income attributable to Phillips 66 | $ | 496 |  | 1,012 |  |  | 881 |  | 1,999 |

Earnings for Phillips 66 decreased $516 million, or 51 percent, in the second quarter of 2016, and $1,118 million, or 56 percent, in the six-month period. The decreases were primarily attributable to lower realized margins in our Refining segment driven by decreased market crack spreads, and lower olefins and polyolefins margins in our Chemicals segment. In addition, earnings from our M&S segment decreased due to the absence of a deferred gain recognized in the first half of 2015 related to the sale in 2013 of the Immingham Combined Heat and Power Plant (ICHP). See Note 5—Assets Held for Sale or Sold, in the Notes to Consolidated Financial Statements, for additional information. These decreases were partially offset by higher equity earnings from DCP Midstream.
See the “Segment Results” section for additional information on our segment results.
Statement of Income Analysis
Sales and other operating revenues for both the second quarter and six-month period of 2016 decreased 23 percent, and purchased crude oil and products decreased 27 percent and 28 percent, respectively. These decreases were primarily due to lower prices for petroleum products, crude oil and NGL.
Equity in earnings of affiliates increased 7 percent in the second quarter of 2016, and decreased 11 percent in the six-month period of 2016. The increase in the second quarter of 2016 was mainly due to improved earnings from DCP Midstream and other equity companies in our Midstream segment as a result of higher volumes, partially offset by lower earnings from CPChem and WRB Refining LP (WRB). The decrease in the six-month period of 2016 was primarily driven by lower earnings from CPChem and WRB, partially offset by higher earnings from DCP Midstream and other Midstream equity companies. Lower equity in earnings from WRB for both periods primarily resulted from lower market crack spreads. See the “Segment Results” section for additional information on DCP Midstream and CPChem earnings.
Net gain on dispositions decreased $133 million and $255 million in the second quarter and six-month period of 2016, respectively. We recognized the deferred gain related to the sale of ICHP in earnings, as our exposure under the indemnity declined, beginning in the third quarter of 2014 and ending in the second quarter of 2015 when the indemnity expired. We recognized $132 million and $242 million of the deferred gain in the second quarter and six-month period of 2015, respectively. See Note 5—Assets Held for Sale or Sold, in the Notes to Consolidated Financial Statements, for additional information.

The Midstream segment gathers, processes, transports and markets natural gas; and transports, fractionates and markets NGL in the United States. In addition, this segment transports crude oil and other feedstocks to our refineries and other locations, delivers refined and specialty products to market, and provides terminaling and storage services for crude oil and petroleum products. The Midstream segment includes our master limited partnership, Phillips 66 Partners LP, as well as our 50 percent equity investment in DCP Midstream.
Earnings from the Midstream segment increased $117 million in the second quarter of 2016 and $115 million in the six-month period.
Transportation earnings were flat in the second quarter of 2016 compared with the second quarter of 2015. Earnings in the second quarter of 2016 reflected higher throughput volumes and improved earnings from equity affiliates, offset by higher operating costs. Transportation earnings increased $7 million in the first half of 2016. The increase was primarily driven by improved volumes and earnings from equity affiliates, partially offset by higher operating costs and the absence of a 2015 first-quarter claim settlement.

Results from our investment in DCP Midstream increased $142 million in the second quarter of 2016 and $158 million in the six-month period. In the second quarter of 2015, DCP Midstream recorded a goodwill impairment, which reduced our equity earnings from DCP Midstream by $126 million, after-tax. The increases for both 2016 periods also reflected higher volumes due to asset growth and higher earnings from DCP Midstream’s equity affiliates. In addition, DCP Midstream’s receipt of funds related to a favorable legal settlement during the first quarter of 2016 benefited earnings for the six-month period. These increases were partially offset by lower volumes related to existing assets and lower commodity prices.
Results from our NGL business decreased $25 million in the second quarter of 2016 and $50 million in the six-month period. The decreases in both periods reflected increased costs associated with growth projects starting up, as well as lower realized margins.

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 lines: Olefins and Polyolefins (O&P) and Specialties, Aromatics and Styrenics (SA&S).
Earnings from the Chemicals segment decreased $105 million, or 36 percent, in the second quarter of 2016, and $152 million, or 31 percent, in the six-month period. The decreases were mainly due to lower realized O&P margins driven by a decline in sales prices, lower equity earnings from CPChem’s SA&S equity affiliates and lower SA&S volumes. In the second quarter of 2015, CPChem recorded additional earnings from business interruption and property damage insurance proceeds related to the 2014 Port Arthur fire. These decreases were partially offset by improved normal alpha olefin (NAO) sales volumes and lower utility costs due to decreases in natural gas prices.

The Refining segment buys, sells and refines crude oil and other feedstocks into petroleum products (such as gasoline, distillates and aviation fuels) at 14 refineries, mainly in the United States and Europe.
Earnings for the Refining segment decreased $455 million, or 75 percent, in the second quarter of 2016 and $907 million, or 79 percent, in the six-month period. The decreases were primarily due to lower realized refining margins resulting from decreased market crack spreads. These decreases were partially offset by higher refining volumes and lower controllable costs as a result of lower turnaround activities and less unplanned downtime. 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 97 percent in the second quarter and six-month period of 2016, respectively, compared with 90 percent and 87 percent in the second quarter and six-month period of 2015, respectively. These increases were primarily due to lower turnaround activities and less unplanned downtime.

Table of Contents
The M&S segment earnings decreased $85 million, or 27 percent, in the second quarter of 2016 and $184 million, or 30 percent, in the six-month period of 2016. The decreases were primarily due to the deferred gain recognized in the first half of 2015 related to the 2013 ICHP sale and lower lubricants earnings resulting from decreased margins and sales volumes. See Note 5—Assets Held for Sale or Sold, in the Notes to Consolidated Financial Statements, for additional information on the deferred ICHP gain. These decreases were partially offset by improved marketing margins.

Net interest consists of interest and financing expense, net of interest income and capitalized interest. Net interest increased in the three-month period ended June 30, 2016, mainly due to lower capitalized interest.
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 second quarter of 2016 primarily resulted from lower accrued environmental costs and remediation expenses. The write-off of certain fixed assets during the second quarter of 2015 contributed to the decreases for both the three-month and six-month periods of 2016.

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 and Phillips 66 Partners’ debt and equity offerings. During the first six months of 2016, we generated $1,413 million in cash from operations. In addition, Phillips 66 Partners raised net proceeds of $669 million in public offerings of common units. Available cash was primarily used for capital expenditures and investments ($1,370 million), repurchases of our common stock ($633 million) and dividend payments on our common stock ($625 million). During the first six months of 2016, cash and cash equivalents decreased by $842 million, to $2,232 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 repayment and share repurchases.
Significant Sources of Capital
Operating Activities
During the first six months of 2016, cash provided by operating activities was $1,413 million, compared with $2,779 million for the first six months of 2015. The decrease was primarily attributable to lower realized refining margins as well as a reduction in distributions from our equity affiliates.
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.
Our operating cash flows are also impacted by distribution decisions made by our equity affiliates, including DCP Midstream, CPChem and WRB. During the first six months of 2016, cash from operations included distributions of $253 million from our equity affiliates, compared with $1,188 million during the same period of 2015. Operating cash flows for the first six months of 2015 included a special distribution from CPChem of $696 million. We cannot control

the amount of future dividends from equity affiliates; therefore, future dividend payments by these companies are not assured.
In the second quarter of 2016, DCP Midstream amended its revolving credit agreement to, among other items, lower its borrowing capacity from $1.8 billion to $700 million and extend the maturity date of the facility from March 2017 to May 2019. As part of the amended terms of the revolving credit agreement, DCP Midstream has certain restrictions on its ability to pay distributions to its owners. DCP Midstream cannot pay distributions, other than certain tax distributions related to the sale of assets, if it has borrowings under the facility or does not meet certain leverage and liquidity thresholds as specified in the agreement. As of June 30, 2016, DCP Midstream was not eligible to make distributions to its owners under the terms of the facility.
Contributions to Phillips 66 Partners LP
In March 2016, we contributed to Phillips 66 Partners a 25 percent interest in our then wholly owned subsidiary, Phillips 66 Sweeny Frac LLC, which owns the Sweeny Fractionator One, an NGL fractionator located within our Sweeny Refinery complex in Old Ocean, Texas, and the Clemens Caverns, an NGL salt dome storage facility located near Brazoria, Texas. Total consideration for the transaction was $236 million, which consisted of Phillips 66 Partners’ issuance of common and general partner units to us, with an aggregate fair value of $24 million, and Phillips 66 Partners’ assumption of a $212 million note payable to us.
In May 2016, we contributed to Phillips 66 Partners the remaining 75 percent interest in Phillips 66 Sweeny Frac LLC and a 100 percent interest in our wholly owned subsidiary, Phillips 66 Plymouth LLC, which owns the Standish Pipeline, a refined petroleum product pipeline system extending from the Ponca City Refinery in Ponca City, Oklahoma, and terminating at the North Wichita Terminal in Wichita, Kansas. Total consideration for the transaction was $775 million, consisting of Phillips 66 Partners’ assumption of $675 million of notes payable to us and the issuance of common units and general partner units to us with an aggregate fair value of $100 million.
Phillips 66 Partners LP Equity Offerings
In May 2016, Phillips 66 Partners completed a public offering of 12,650,000 common units representing limited partner interests, at a public offering price of $52.40 per unit. The net proceeds at closing were $656 million. Phillips 66 Partners used these net proceeds to repay a portion of the notes assumed in the May transaction discussed above.
In June 2016, Phillips 66 Partners began issuing common units under a continuous offering program, which allows for the issuance of up to an aggregate of $250 million of Phillips 66 Partners’ common units, in amounts, at prices and on terms to be determined by market conditions and other factors at the time of the offerings. We refer to this as an at-the-market, or ATM, program. During the three months ended June 30, 2016, on a settlement-date basis, Phillips 66 Partners issued an aggregate of 262,858 common units under the ATM program, generating net proceeds of approximately $14 million.
Credit Facilities and Commercial Paper
As of June 30, 2016, no amount had been drawn under our $5 billion credit facility; however, $51 million in letters of credit had been issued that were supported by this facility. As of June 30, 2016, $40 million was outstanding under the $500 million revolving credit agreement of Phillips 66 Partners.
We have a $5 billion commercial paper program, supported by our credit facility, for short-term working capital needs. Commercial paper maturities are generally limited to 90 days. As of June 30, 2016, we had no outstanding commercial paper.
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
In April 2012, in connection with our separation from ConocoPhillips, we entered into an agreement to guarantee 100 percent of certain outstanding debt obligations of Merey Sweeny, L.P. (MSLP). At June 30, 2016, the aggregate principal amount of MSLP debt guaranteed by us was $140 million.
In June 2016, the operating lease commenced on our new headquarters facility in Houston, Texas, after construction was deemed substantially complete. Under this lease agreement, we have a residual value guarantee with a maximum future exposure of $554 million. The operating lease has a term of five years 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 have residual value guarantees associated with railcar and airplane leases with maximum future exposures totaling $376 million. We have other guarantees with maximum future exposures totaling $112 million, which consist primarily of guarantees to fund the short-term cash liquidity deficits of certain joint ventures and guarantees of the lease payment obligations of a joint venture. These guarantees generally extend up to 8 years or the life of the venture.
For additional information about guarantees, see Note 10—Guarantees, in the Notes to Consolidated Financial Statements.
Capital Requirements
For information about our capital expenditures and investments, see the “Capital Spending” section.
Our debt balance at both June 30, 2016, and December 31, 2015, was $8.9 billion. Our debt-to-capital ratio was 27 percent at both June 30, 2016, and December 31, 2015. Our target debt-to-capital ratio is between 20 and 30 percent.
On May 4, 2016, our Board of Directors declared a quarterly cash dividend of $0.63 per common share, which represented a 12.5 percent increase from the previous quarter. The dividend was paid on June 1, 2016, to shareholders of record at the close of business on May 18, 2016. On July 13, 2016, our Board of Directors declared a quarterly cash dividend of $0.63 per common share. The dividend is payable on September 1, 2016, to shareholders of record at the close of business on August 18, 2016.
On October 9, 2015, our Board of Directors increased our current share repurchase authorization by $2 billion resulting in a total authorization of $4 billion. Since July 2012, including this current authorization, our Board of Directors has authorized repurchases of our outstanding common stock totaling up to $9 billion. The share repurchases 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 second quarter of 2016, we repurchased 2,932,668 shares at a cost of $242 million. Since the inception of our share repurchases in 2012 through June 30, 2016, we have repurchased a total of 100,335,164 shares at a cost of $7,029 million. Shares of stock repurchased are held as treasury shares.
We and our co-venturer in WRB each made a $75 million partner loan to WRB in the first quarter of 2016 to provide for WRB’s short-term operating needs. In May 2016, we and our co-venturer executed agreements to loan Dakota Access, LLC (DAPL) up to $2,256 million and Energy Transfer Crude Oil Company, LLC (ETCOP) up to $227 million through 2018. As of June 30, 2016, DAPL and ETCOP have borrowed $382 million and $46 million, respectively. Our 25 percent share of those loans was $95 million and $12 million, respectively.
On May 1, 2015, the U.S. Department of Transportation issued a final rule focused on the safe transportation of flammable liquids by rail. The final rule, which is being challenged, subjects new and existing railcars transporting crude oil in high volumes to heightened design standards, including thicker tank walls and heat shields, improved pressure relief valves and enhanced braking systems. We are currently evaluating the impact of the new regulations on our crude oil railcar fleet, which is mostly held under operating leases. The regulations become effective subsequent to the expiration dates of our leases. Although we have no direct contractual obligation to retrofit these leased railcars, certain leases are subject to residual value guarantees. Under the lease terms, we have the option either to purchase the railcars
44

Table of Contents
or to return them to the lessors. If railcars are returned to the lessors, we may be required to make the lessors whole under the residual value guarantees, which are subject to a cap. The current market demand for crude oil railcars is low, which has resulted in a significant decline in crude oil railcar prices. Due to current market uncertainties, it is difficult to estimate the future market value for our railcars at the end of their lease terms. However, at this time, if crude oil railcar prices remain low, it is possible we may incur a charge in the future to recognize our obligation under the residual value guarantees. As of June 30, 2016, our maximum future exposure under the residual value guarantees was approximately $330 million.

Midstream
During the first six months of 2016, 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 $110 million, primarily for maintenance capital expenditures for existing assets and expansion capital expenditures including investments in the Sand Hills Pipeline and Panola Pipeline joint ventures. DCP Midstream continues to focus on disciplined capital spending in the current market downturn.
During the first six months of 2016, capital spending in our Midstream segment included construction activities related to our Freeport Liquid Petroleum Gas Export Terminal project; increasing expansion at our crude oil and petroleum products terminal located near Beaumont, Texas; and spending associated with return, reliability and maintenance projects in our Transportation and NGL businesses. In addition to the Freeport Liquid Petroleum Gas Export Terminal and Beaumont projects, our major construction activities in progress included the development by our joint ventures, DAPL and ETCOP, of two crude oil pipelines. We own a 25 percent interest in each joint venture, with our co-venturers holding the remaining 75 percent interest and acting as operator of both the DAPL and ETCOP pipeline systems.
Chemicals
During the first six months of 2016, 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 $1,081 million, primarily for its U.S. Gulf Coast Petrochemicals Project. We currently expect CPChem to self-fund its capital program in 2016.

Table of Contents
Refining
Capital spending for the Refining segment during the first six months of 2016 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 in progress include:

• | Installation of facilities to comply with U.S. Environmental Protection Agency (EPA) Tier 3 gasoline regulations at the Sweeny, Alliance, Bayway and Lake Charles refineries.

• | Installation of facilities to improve processing of advantaged crudes at Billings refinery.

• | Installation of facilities to improve clean product yield at Bayway and Ponca City refineries.

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 six months of 2016 was primarily for reliability and maintenance projects and projects targeted at growing our international marketing business.
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
We are subject to the same numerous international, federal, state and local environmental laws and regulations as other companies in our industry. For a discussion of the most significant of these environmental laws and regulations, including those with associated remediation obligations, see the “Environmental” section in Management’s Discussion and Analysis of Financial Condition and Results of Operations on pages 56, 57, 58 and 59 of our 2015 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, 2015, we reported that we had been notified of potential liability under CERCLA and comparable state laws at 36 sites within the United States. During the first six months of 2016, we resolved one site, leaving 35 sites with potential liability at June 30, 2016.
At June 30, 2016, our total environmental accrual was $486 million, compared with $485 million at December 31, 2015. We expect to incur a substantial amount of these expenditures within the next 30 years. Notwithstanding any of the foregoing, and as with other companies engaged in similar businesses, environmental costs and liabilities are inherent concerns in 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. We consider and take into account future GHG emissions in designing and developing major facilities and projects, and implement energy efficiency initiatives to reduce such emissions. 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, if enacted, 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 on pages 59 and 60 of our 2015 Annual Report on Form 10-K.
NEW ACCOUNTING STANDARDS
In June 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 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 will result in the more timely recognition of losses. Public business entities should apply the guidance in ASU 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 2016-13 and assessing the impact on our financial statements.
In March 2016, the FASB issued ASU No. 2016-07, “Equity Method and Joint Ventures (Topic 323): Simplifying the Transition to the Equity Method of Accounting.” The new standard eliminates the requirement that an investor retroactively apply equity method accounting when an investment that it had accounted for by another method initially qualifies for the equity method. Public business entities should apply the guidance in ASU 2016-07 for annual periods beginning after December 15, 2016, including interim periods within those annual periods, with early adoption permitted.
47

Table of Contents
We are currently evaluating the provisions of ASU 2016-07, but do not expect any significant impact on our financial statements.
In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842).” In the new standard, the FASB modified its determination of whether a contract is a lease rather than whether a lease is a capital or operating lease under the previous accounting principles generally accepted in the United States (GAAP). A contract represents a lease if a transfer of control occurs over an identified property, plant and equipment for a period of time in exchange for consideration. Control over the use of the identified asset includes the right to obtain substantially all of the economic benefits from the use of the asset and the right to direct its use. The FASB continued to maintain two classifications of leases — financing and operating — which are substantially similar to capital and operating leases in the previous lease guidance. Under the new standard, recognition of assets and liabilities arising from operating leases will require recognition on the balance sheet. The effect of all leases in the statement of comprehensive income and the statement of cash flows will be largely unchanged. Lessor accounting will also be largely unchanged. Additional disclosures will be required for financing and operating leases for both lessors and lessees. Public business entities should apply the guidance in ASU 2016-02 for annual periods beginning after December 15, 2018, including interim periods within those annual periods. Early adoption is permitted. We are currently evaluating the provisions of ASU 2016-02 and assessing its impact on our financial statements.
In January 2016, the FASB issued ASU No. 2016-01, “Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities,” to meet its objective of providing more decision-useful information about financial instruments. The majority of this ASU’s provisions amend only the presentation or disclosures of financial instruments; however, one provision will also affect net income. Equity investments carried under the cost method or lower of cost or fair value method of accounting, in accordance with current GAAP, will have to be carried at fair value upon adoption of ASU 2016-01, 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. Public business entities should apply the guidance in ASU 2016-01 for annual periods beginning after December 15, 2017, and interim periods within those annual periods, with early adoption prohibited. We are currently evaluating the provisions of ASU 2016-01. Our initial review indicates that ASU 2016-01 will have a limited impact on our financial statements.
In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606).” The new standard converged guidance on recognizing revenues in contracts with customers under GAAP and International Financial Reporting Standards. This ASU is intended to improve comparability of revenue recognition practices across entities, industries, jurisdictions and capital markets. In August 2015, the FASB issued ASU 2015-14, “Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date.” The amendment in this ASU defers the effective date of ASU 2014-09 for all entities for one year. Public business entities should apply the guidance in ASU 2014-09 to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Earlier adoption is permitted only as of annual reporting periods beginning after December 31, 2016, including interim reporting periods within that reporting period. Retrospective or modified retrospective application of the accounting standard is required. We are currently evaluating the provisions of ASU 2014-09 and assessing the impact on our financial statements. As part of our assessment work to-date, we have formed an implementation work team, completed training on the new ASU’s revenue recognition model and are continuing our contract review and documentation.

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Market risks at June 30, 2016, do not differ materially from the risks discussed under Item 7A in our 2015 Annual Report on Form 10-K.
Item 4. CONTROLS AND PROCEDURES
We maintain disclosure controls and procedures designed to ensure that information required to be disclosed in reports we file or submit under the Securities Exchange Act of 1934, as amended (the Act), is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and that such information is accumulated and communicated to management, including our principal executive and principal financial officers, as appropriate, to allow timely decisions regarding required disclosure. As of June 30, 2016, with the participation of management, our Chairman and Chief Executive Officer and our Executive Vice President, Finance and Chief Financial Officer carried out an evaluation, pursuant to Rule 13a-15(b) of the Act, of the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) of the Act). Based upon that evaluation, our Chairman and Chief Executive Officer and our Executive Vice President, Finance and Chief Financial Officer concluded that our disclosure controls and procedures were operating effectively as of June 30, 2016.
There have been no changes in our internal control over financial reporting, as defined in Rule 13a-15(f) of the Act, in the quarterly period ended June 30, 2016, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

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 no new matters that arose during the second quarter of 2016. In addition, no material developments occurred with respect to matters previously reported in our 2015 Annual Report on Form 10-K or our Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2016. While it is not possible to accurately predict the final outcome of these 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 SEC regulations.
Our U.S. refineries are implementing two separate consent decrees, regarding alleged violations of the Federal Clean Air Act, with the EPA, six 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.
Item 1A. RISK FACTORS
There have been no material changes from the risk factors disclosed in Item 1A of our 2015 Annual Report on Form 10-K.
