1.BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation
General
As used in this report, the terms “Valero,” “we,” “us,” or “our” may refer to Valero Energy Corporation, one or more of its consolidated subsidiaries, or all of them taken as a whole.

These unaudited financial statements have been prepared in accordance with United States (U.S.) generally accepted accounting principles (GAAP) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X of the Securities Exchange Act of 1934. Accordingly, they do not include all of the information and notes required by U.S.GAAP for complete financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation have been included. All such adjustments are of a normal recurring nature unless disclosed otherwise. Financial informationOperating results for the three and ninethree months ended September 30, 2016 and 2015 included in these Condensed Notes to Consolidated Financial Statements is derived from our unaudited financial statements. Operating results for the three and nine months ended September 30, 2016March 31, 2017 are not necessarily indicative of the results that may be expected for the year ending December 31, 2016.2017.

The balance sheet as of December 31, 20152016 has been derived from our audited financial statements as of that date. For further information, refer to our financial statements and notes thereto included in our annual report on Form 10-K for the year ended December 31, 20152016.

Reclassifications
Certain amounts reported asAs of December 31, 2015 have been reclassified in order to conform to the 2016 presentation, including the retrospective adoption of certain amendments to the Accounting Standards Codification (ASC) effective January 1, 2016.2017, we revised our reportable segments to reflect a new reportable segment — VLP. The adoptionresults of the amendments to ASC Subtopic 835-30, “Interest–ImputationVLP segment include the results of Interest,” resulted in the reclassification of certain debt issuance costs from “deferred charges and other assets, net” to “debt and capital lease obligations, less current portion.” The adoption of the amendments to ASC Topic 740, “Income Taxes” resulted in the reclassification of current deferred income tax assets and current deferred income tax liabilities to noncurrent deferred income tax liabilities. The following table presentsValero Energy Partners LP (VLP), our previously reported balance sheet line itemsmajority-owned master limited partnership.

Significant Accounting Policies
Use of Estimates
The preparation of financial statements in conformity with U.S.GAAP requires us to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. On an ongoing basis, we review our estimates based on currently available information. Changes in facts and circumstances may result in revised estimates.

Accounting Pronouncements Adopted During the Period
In FebruaryJuly 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2015-11, “Inventory (Topic 330),” to simplify the measurement of inventory measured using the first-in, first-out or average cost methods. The provisions of ASC Topic 810, “Consolidation,this ASU require the inventory to be measured at the lower of cost and net realizable value rather than the lower of cost or market. Net realizable value is defined as the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The provisions of this ASU are to be applied prospectively and are effective for annual reporting periods beginning after December 15, 2016, and interim reporting periods within those annual periods, with early adoption permitted. Our adoption of this ASU effective January 1, 2017 did not affect our financial position or results of operations since the majority of our inventory is stated at last-in, first-out (LIFO).

In October 2016, the FASB issued ASU No. 2016-16, “Income Taxes (Topic 740), were amended to improve consolidation guidancethe accounting for certain typesthe income tax consequences of legal entities.intra-entity transfers of assets other than inventory.

These provisions are effective for annual reporting periods beginning after December 15, 2015,2017, and interim reporting periods within those annual periods. Withperiods, with early adoption permitted. The provisions should be applied on a modified retrospective basis with a cumulative-effect adjustment to the opening balance of retained earnings as of the beginning of the period of adoption to recognize the income tax consequences of intra-entity transfers of assets that occurred before the adoption date. Our early adoption of this guidanceASU using the modified retrospective method effective January 1, 2017 did not have a material affect on our financial position or results of operations. Adoption of this guidance more accurately reflects the economics of an intra-entity asset transfer when it occurs by eliminating the previous exception that prohibited the recognition of the income tax consequences of an intra-entity asset transfer until the asset had been sold to an outside party.

In October 2016, we determinedthe FASB issued ASU No. 2016-17, “Consolidation (Topic 810),” to provide guidance on how a reporting entity that Valero Energy Partners LP (VLP) is a VIE. Since we previously consolidatedsingle decision maker of a variable interest entity (VIE) should treat indirect interests in the financial statementsentity held through related parties that are under common control with the reporting entity when determining whether it is the primary beneficiary. The provisions of VLP,this ASU are effective for annual reporting periods beginning after December 15, 2016, and interim reporting periods within those annual periods, with early adoption permitted. The provisions should be applied on a retrospective basis to all relevant prior periods beginning with the fiscal year in which the VIE guidance was adopted with a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. Our adoption of this guidanceASU effective January 1, 2017 did not affect our financial position or results of operations. See Note 9 for disclosures related to our consolidated VIEs.

In April 2015,January 2017, the FASB issued ASU No. 2017-01, “Business Combinations (Topic 805),” to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The provisions of ASC Subtopic 835-30, “Interest–Imputationthis ASU provide a more robust framework to use in determining when a set of Interest,” were amended to simplifyassets and activities is a business by clarifying the presentation of debt issuance costs. The guidance requires that debt issuance costsrequirements related to a note be reported in the balance sheet as a direct deduction from the face amount of that note, consistent with debt discounts,inputs, processes, and that amortization of debt issuance costs be reported as interest expense. In August 2015, these provisions were further amended with guidance from the Securities and Exchange Commission staff, which provides that the staff would not object to an entity deferring and presenting debt issuance costs related to a line-of-credit arrangement as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement.outputs. These provisions are to be applied retrospectivelyprospectively and are effective for annual reporting periods beginning after December 15, 2015, and interim periods within those annual periods.

However, more of debt issuance costsour future acquisitions may be accounted for as interest expense. See “Basis of Presentation–Reclassifications” above for the reclassified presentation in our balance sheet. Debt issuance costs associated with our line-of-credit arrangements will continue to be reported in the balance sheet as “deferred charges and other assets, net.”asset acquisitions.

Accounting Pronouncements Not Yet Adopted
In May 2015,2014, the provisions of ASC Topic 820, “Fair Value Measurements,FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606),were amended to removeclarify the requirement to categorize within the fair value hierarchy all investmentsprinciples for which fair valuerecognizing revenue. The ASU is measured using the net asset value per share practical expedient. The guidance also removes the requirement to make certain disclosures for all investments that are eligible to be measured using the net asset value per share practical expedient and limits those disclosures to investments for which the entity has elected to measure the fair value using that practical expedient. These provisions are to be applied retrospectively and are effective for annual reporting periods beginning after December 15, 2015, and2017, including interim reporting periods within those annual periods. TheWe recently completed our evaluation of the provisions of this ASU and concluded that our adoption of the ASU will not materially change the amount or timing of revenues recognized by us, nor will it materially affect our financial position. The majority of our revenues are generated from the sale of refined petroleum products and ethanol. These revenues are largely based on the current spot (market) prices of the products sold, which represents consideration specifically allocable to the products being sold on a given day, and we recognize those revenues upon delivery and transfer of title to the products to our customers. The time at which delivery and transfer of title occurs is the point when our control of the products is transferred to our customers and when our performance obligation to our customers is fulfilled. We will adopt this guidanceASU effective January 1, 2016 did not affect our financial position or results of operations.

In September 2015,we expect to use the provisionsmodified retrospective method of ASC Topic 805, “Business Combinations,” were amended to simplifyadoption as permitted by the accounting and reportingASU. Under that method, the cumulative effect of adjustments made to provisional amountsinitially applying the standard is recognized in a business combination. The amendment requires thatas an acquirer (i) record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date and (ii) present separately on the statement of income or disclose in the notes the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized asopening balance of retained earnings, and revenues reported in the acquisition date. These provisions are effective for annual reporting periods beginning after December 15, 2015, and interim periods within those annual periods, and should be applied prospectively to adjustments made to provisional amounts that occur after the effective date. The adoption of this guidance effective January 1, 2016 did not affect our financial position or results of operations; however, it may result in changesprior to the manner in which adjustments to provisional amounts recognized in a future business combination, if any, are presented in our financial statements.

In November 2015, the provisions of ASC Topic 740, “Income Taxes,” were amended to simplify the presentation of deferred income taxes. The amendments require that deferred tax liabilities and assets be classified as noncurrent in a classified balance sheet. The amendments are effective for financial statements for annual periods beginning after December 15, 2016, and interim periods within those annual periods, with early adoption permitted as of the beginning of any interim or annual period. The amendments may be applied either prospectively to all deferred tax liabilities and assets or retrospectively to all periods presented. Entities applying the guidance retrospectively should disclose in the first interim and first annual perioddate of adoption the nature ofare not changed. During 2017, we are developing our revenue disclosures and reason for the change inenhancing our accounting principle and quantitative information about the effects of the accounting change on prior periods. Effective January 1, 2016, we adopted this guidance on a retrospective basis, but such adoption did not materially affect our financial position and it did not impact our results of operations. See “Basis of Presentation–Reclassifications” above for the reclassified presentation. Adoption of this guidance simplifies the future presentation of our deferred income tax assets and liabilities.

In March 2016, the provisions of ASC Topic 718, “Compensation–Stock Compensation,” were amended to simplify the accounting and reporting for employee share-based payments. These amendments involve several aspects of the accounting for share-based payment transactions, including accounting for income taxes as it pertains to the recognition of excess tax benefits and tax deficiencies in the statements of income, forfeitures, minimum statutory tax withholding requirements, as well as classification of excess tax benefits and employee taxes paid in the statement of cash flows. These provisions are effective for public companies for annual reporting periods beginning after December 15, 2016, and interim periods within those annual periods, with early adoption permitted. An entity that elects early adoption must adopt all of the amendments in the same period. The amendments provide specific transition and disclosure guidance for each provision. Effective January 1, 2016, we adopted this guidance on a prospective basis, and such adoption did not materially affect our financial position, results of operations, or cash flows. Excess tax benefits, which were previously reported in cash flows from financing activities, are currently reported in cash flows from operating activities.

Accounting Pronouncements Not Yet Adopted
In May 2014, the ASC was amended and a new accounting standard, ASC Topic 606, “Revenue from Contracts with Customers,” was issued to clarify the principles for recognizing revenue. The standard is effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within those annual periods. We have been evaluating and continue to evaluate the provisions of this standard and its impact on our business processes, business and accounting systems, and financial statements and related disclosures. A multi-disciplined implementation team has gained an understanding of the standard’s revenue recognition model, is completing the review and documentation of our contracts, and is analyzing whether enhancements are needed to our business and accounting systems.

In July 2015, the provisions of ASC Topic 330, “Inventory” were amended to simplify the measurement of inventory measured using the first-in, first-out or average cost methods. These provisions are to be applied prospectively and are effective for annual reporting periods beginning after December 15, 2016, and interim periods within those annual periods, with early adoption permitted. The adoption of this guidance effective January 1, 2017 will not affect our financial position or results of operations.

In January 2016, the provisions of ASC Subtopic 825-10,FASB issued ASU No. 2016-01, “Financial Instruments–Instruments—Overall (Subtopic 825-10), were amended to enhance the reporting model for financial instruments regarding certain aspects of recognition, measurement, presentation, and disclosure. TheseThe provisions of this ASU are effective for annual reporting periods beginning after December 15, 2017, and interim reporting periods within those annual periods. We are currently evaluatingThis ASU is to be applied using a cumulative-effect adjustment to the effect that adoptingbalance sheet as of the beginning of the fiscal year of adoption. The adoption of this standardASU effective January 1, 2018 will have onnot affect our financial statements and relatedposition or results of operations, but will result in revised disclosures.

In February 2016, the ASC was amended and a new accounting standard, ASC Topic 842,FASB issued ASU No. 2016-02, “Leases (Topic 842), was issued to increase the transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The new standard is effective for annual reporting periods beginning after December 15, 2018, and interim reporting periods within those annual periods, with early adoption permitted. We have been evaluatinganticipate adopting the new standard on January 1, 2019 and continuewe expect to evaluateuse the modified retrospective method of adoption as permitted by the ASU. We recently completed our evaluation of the provisions of this standard, and its impact on our business processes, business and accounting systems, and financial statements and related disclosures. Aa multi-disciplined implementation team has gained an understanding of the standard’s accounting and disclosure provisions of the standardprovisions. This team is developing enhanced contracting and is in the process of analyzing the impactslease evaluation processes and information systems to our businesssupport such processes, as well as new and accounting systems, including the development of newenhanced accounting systems to account for our leases and support the required disclosures. We continue to evaluate the effect that adopting this standard will have on our financial statements and related disclosures.

In October 2016,March 2017, the FASB issued ASU 2017-07, “Compensation—Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.” The new standard requires that an employer report the service cost component in the same line item as other compensation costs arising from services rendered by the pertinent employees during the period. It also requires the other components of net periodic pension cost and net periodic postretirement benefit cost to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations. This ASU is to be applied retrospectively for income statement items and prospectively for any capitalized benefit costs. The provisions of ASC Topic 740, “Income Taxes,” were amended to improve the accounting for the income tax consequences of intra-entity transfers of assets other than inventory. The amendments require an entity to recognize the income tax consequences of intra-entity transfers of assets other than inventory immediately when the transfer occurs. These provisionsthis ASU are effective for annual reporting periods beginning after December 15, 2017, and interim reporting periods within those annual periods, with early adoption permitted. The amendments should be applied on a modified retrospective basis with a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption for the recognition of income tax consequences of intra-entity transfers of assets other than inventory that occur before the adoption date. The adoption of this guidance effective January 1, 2018 is not expected to materially affect our financial position or results of operations; however, certain deferred charges associated with intra-entity transfers of assets other than inventory will be reported in our balance sheet primarily as a reduction to our deferred income tax liabilities.operations.

In October 2016, the provisions of ASC Topic 810, “Consolidation,” were amended to provide guidance on how a reporting entity that is a single decision maker of a variable interest entity (VIE) should treat indirect interests in the entity held through related parties that are under common control with the reporting entity when determining whether it is the primary beneficiary. These provisions are effective for annual reporting periods beginning after December 15, 2016, and interim periods within those annual periods, with early adoption permitted. The amendments should be applied on a retrospective basis to all relevant prior periods beginning with the fiscal year in which the VIE guidance was adopted with a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. The adoption of this guidance effective January 1, 2017 will not affect our financial position or results of operations.

Inventories$6,025
 $5,709

Inventories are valued at the lower of cost or market. As of December 31, 2015, we had a valuation reserve of $766 million in order to state our inventories at market. During the three months ended March 31, 2016, we (i) transferred ownership of all of our assets in Aruba, other than certain hydrocarbon inventories and working capital, to Refineria di Aruba N.V. (RDA), an entity wholly-owned by the Government of Aruba (GOA), (ii) settled our obligations under various agreements with the GOA, including agreements that required us to dismantle our leasehold improvements under certain conditions, and (iii) sold the working capital of our Aruba operations, including hydrocarbon inventories, to the GOA, CITGO Aruba Refining N.V. (CAR), and CITGO Petroleum Corporation (together with CAR and certain other affiliates, collectively, CITGO). We refer to this transaction as the “Aruba Disposition.” The agreements associated with the Aruba Disposition were finalized in September 2016, including approval of such agreements by the Aruba Parliament. We no longer own any assets or have any operations in Aruba.

In June 2016, we recognized an asset impairment loss of $56 million representing all of the remaining carrying value of our long-lived assets in Aruba. These assets were primarily related to our crude oil and refined products terminal and transshipment facility in Aruba (collectively, the Aruba Terminal), which were includedrecorded a change in our refining segment. We recognized the impairment loss atlower of cost or market inventory valuation reserve that time because we concluded that it was more likely than not that we would ultimately transfer ownership of these assets to the GOA asresulted in a result of agreements entered into in June 2016 between the GOA and CITGO providing for, among other things, the GOA’s lease of those assets to CITGO. (See Note 12 for disclosure related to the method to determine fair value.) We had previously written off all of the carrying value of the long-lived assets of the refining operations (the Aruba Refinery) and recognized an asset retirement obligation upon the suspension of operations of those assets in 2012. Therefore, there was no other significant effectnetbenefit to our results of operations from the Aruba Disposition during the three and nine months ended September 30, 2016, except with respect to income taxes, which are discussed below. In addition, the net cash impact to us upon effectiveness of the Aruba Disposition on October 1, 2016, was not significant.$293 million.

In SeptemberAs of March 31, 2017 and December 31, 2016, the replacement cost (market value) of LIFO inventories exceeded their LIFO carrying amounts by $1.8 billion and in connection with the Aruba Disposition,$1.9 billion, respectively. As of March 31, 2017 and December 31, 2016, our U.S. subsidiaries were unable to collect any outstanding debt obligations owed to them bynon-LIFO inventories accounted for $663 million and $641 million, respectively, of our Aruba subsidiaries, which resulted in the recognition by us of an income tax benefit in the U.S. of $42 million during the three and nine months ended September 30, 2016. We had no income tax effect in Aruba from the cancellation of debt or other effects of the Aruba Disposition because of net operating loss carryforwards associated with our operations in Aruba against which we had previously recorded a full valuation allowance.total inventories.

Inventories are valued at the lower of cost or market. As of December 31, 2015, we had a valuation reserve of $766 million in order to state our inventories at market. As of September 30, 2016, we reevaluated our inventories and determined that our cost was lower than market. As a result, for the nine months ended September 30, 2016, we recorded a change in our lower of cost or market inventory valuation reserve that resulted in a net benefit to our results of operations of $747 million. The income statement benefit for the nine months ended September 30, 2016 differs from the change in the balance sheet reserve due to the foreign currency effect of inventories held by our international operations.

As of September 30, 2016, the replacement cost (market value) of last-in, first-out (LIFO) inventories exceeded their LIFO carrying amounts by $1.2 billion. As of September 30, 2016 and December 31, 2015, our non-LIFO inventories accounted for $675 million and $668 million, respectively, of our total inventories.

During the nine months ended September 30, 2016, VLP borrowed $139 million and $210 million under the VLP Revolver in connection with VLP’s acquisitions from us of the McKee Terminal Services Business in April 2016 and the Meraux and Three Rivers Terminal Services Business in September 2016, respectively, and made no repayments under the VLP Revolver. During the nine months ended September 30, 2015, VLP borrowed $200 million under the VLP Revolver in connection with VLP’s acquisition from us of the Houston and St. Charles Terminal Services Business and repaid $25 million on the VLP Revolver. Borrowings outstanding under the VLP Revolver were $524 million and $175 million as of September 30, 2016 and December 31, 2015, respectively.

Canadian Revolver
One of our Canadian subsidiaries has a C$50 million committed revolving credit facility (the Canadian Revolver) that matures in November 2016. No amounts were outstanding under the Canadian Revolver as of September 30, 2016 or December 31, 2015, and we had no borrowings under the Canadian Revolver during the nine months ended September 30, 2016 and 2015.

Accounts Receivable Sales Facility
We have an accounts receivable sales facility with a group of third-party entities and financial institutions to sell eligible trade receivables on a revolving basis. In July 2016, we amended our agreement to decrease the facility from $1.4 billion to $1.3 billion and extended the maturity date to July 2017. Proceeds from the sale of receivables under this facility are reflected as debt. Under this program, one of our marketing subsidiaries (Valero Marketing) sells eligible receivables, without recourse, to another of our subsidiaries (Valero Capital), whereupon the receivables are no longer owned by Valero Marketing. Valero Capital, in turn, sells an undivided percentage ownership interest in the eligible receivables, without recourse, to the third-party entities and financial institutions. To the extent that Valero Capital retains an ownership interest in the receivables it has purchased from Valero Marketing, such interest is included in our financial statements solely as a result of the consolidation of the financial statements of Valero Capital with those of Valero Energy Corporation; the receivables are not available to satisfy the claims of the creditors of Valero Marketing or Valero Energy Corporation.

During the nine months ended September 30, 2016 and 2015, we had no proceeds from or repayments under the accounts receivable sales facility.

As of March 31, 2017 and December 31, 2016, the weighted-average interest rate on the VLP Revolver was 2.3125 percent. As of March 31, 2017 and December 31, 2016, the weighted-average interest rate on the accounts receivable sales facility was 1.4805 percent and 1.3422 percent, respectively.
(a)As of September 30, 2016, the actual availability under the accounts receivable sales facility fell below the facility borrowing capacity to $1.2 billion primarily due to a decrease in eligible trade receivables as a result of the current market price environment for the finished products that we produce.

Non-Bank Debt
During the nine months ended September 30, 2016, we issued $1.25 billion of 3.4 percent senior notes due September 15, 2026. Proceeds from this debt issuance totaled $1.246 billion. We also incurred $10 million of debt issuance costs. During the nine months ended September 30, 2016, we had no repayments under our non-bank debt.

Capital Leases
In October 2016,January 2017, we redeemed our 6.125 percent senior notes with a maturity date of June 15, 2017 for$778 million, or 103.70 percent of stated value, and our 7.2 percent senior notes with a maturity date of October 15, 2017 for $213 million, or 106.27 percent of stated value.

During the nine months ended September 30, 2015, we issued $600 million of 3.65 percent senior notes due March 15, 2025 and $650 million of 4.9 percent senior notes due March 15, 2045. Proceeds from these debt issuances totaled $1.246 billion. We also incurred $12 million of debt issuance costs. In addition, we made scheduled debt repayments of $400 million related to our 4.5 percent senior notes and $75 million related to our 8.75 percent debentures.

Other Debt
In June 2016, a joint venture in Canada that we consolidate entered into a C$72 million senior secured credit facility. This non-revolving credit facility bears interest at a fixed rate (as defined by the lender) plus the applicable margin and matures in June 2023. During the nine months ended September 30, 2016, borrowings under this facility totaled C$72 million and debt repayments totaled C$2 million. As of September 30, 2016, the effective interest rate of this facility was 3.85 percent.

Capitalized Interest
Capitalized interest was $14 million and $18 million for the three months ended September 30, 2016 and 2015, respectively, and $53 million and $50 million for the nine months ended September 30, 2016 and 2015, respectively.

Capital Lease Obligations
In October 2016, we entered into agreements under which we expect to lease storage tanks located at three of our refineries. The leases will not commence until certain required regulatory permitting occurs. The lease agreements will be accounted for as capital leases and we expect to recognizerecognized capital lease assets and related obligations of approximately $490 million.million for the lease of storage tanks located at three of our refineries. These capital lease agreements have initial terms of 10 years each and each agreement haswith successive 10-year automatic renewal terms.

5.4.COMMITMENTS AND CONTINGENCIES

Environmental Matters
We are involved, together with several other companies, in an environmental cleanup in the Village of Hartford, Illinois (the Village) and during 2015, one of these companies assumed the ongoing remediation in the Village pursuant to a federal court order. We had previously conducted an initial response in the Village, along with other companies, pursuant to an administrative order issued by the U.S. Environmental Protection Agency (EPA). The parties involved in the initial response may have further claims among themselves for costs already incurred. We also continue to be engaged in site assessment and interim measures at the adjacent shutdown refinery site, which we acquired as part of an acquisition in 2005, and we are in litigation with other potentially responsible parties and the Illinois EPA relating to the remediation of the site. In each of these matters, we have various defenses, limitations, and potential rights for contribution from the other responsible parties. We have recorded a liability for our expected contribution obligations. However, because



9




VALERO ENERGY CORPORATION
CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

of the unpredictable nature of these cleanups, the methodology for allocation of liabilities, and the State of Illinois’ failure to directly sue third parties responsible for historic contamination at the site, it is reasonably possible that we could incur a loss in a range of $0 to $200 million in excess of the amount of our accrual to ultimately resolve these matters. Factors underlying this estimated range are expected to change from time to time, and actual results may vary significantly from this estimate.

Litigation Matters
We are party to claims and legal proceedings arising in the ordinary course of business. We have not recorded a loss contingency liability with respect to some of these matters because we have determined that it is remote that a loss has been incurred. For other matters, we have recorded a loss contingency liability where we have determined that it is probable that a loss has been incurred and that the loss is reasonably estimable. These loss contingency liabilities are not material to our financial position. We re-evaluate and update our loss contingency liabilities as matters progress over time, and we believe that any changes to the recorded liabilities will not be material to our financial position, results of operations, or liquidity.

(a)The noncontrolling interests relate to third-party ownership interests in VIEs for which we are the primary beneficiary and therefore consolidate. See Note 96 for information about our consolidated VIEs.
(b)“Transfers from noncontrolling interests, net of tax” reflects an adjustment to reallocate VLP equity activity between our ownership interest in VLP and that of the noncontrolling interests. This reallocation occurred due to the expiration of the subordination period on August 10, 2016 and as a result of a change in ownership interest resulting from VLP’s issuances of equity following that date. During the subordination period, we held certain common units in VLP that were subordinate to other common units held by us and VLP’s public unitholders. Upon expiration of the subordination period, all unitholders have equal ownership rights.

9.6.VARIABLE INTEREST ENTITIES

Overview
In the normal course of business, we have financial interests in certain entities that have been determined to be VIEs. We consolidate a VIE when we have a variable interest in an entity for which we are the primary beneficiary such that we have (a) the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and (b) the obligation to absorb losses of or the right to receive benefits from the VIE that could potentially be significant to the VIE. In order to make this determination, we evaluated our contractual arrangements with the VIEs, including arrangements for the use of assets, purchases of products and services, debt, equity, or management of operating activities.

The following discussion summarizes our involvement with our VIEs:

Our significant VIE’s include:
VLP, is a publicly traded master limited partnership whose common limited partner units are traded on the New York Stock Exchange under “VLP.” We formed VLP in July 2013 to own, operate, develop, and acquire crude oil and refined petroleum products pipelines, terminals, and other transportation and logistics assets. VLP’s assets include crude oilassets; and refined products pipeline and terminal systems in the U.S. Gulf Coast and U.S. Mid-Continent regions that are integral to the operations of ten of our refineries. As of September 30, 2016, we owned a 66.6 percent limited partner interest and a 2 percent general partner interest in VLP, and public unitholders owned a 31.4 percent limited partner interest.

VLP was determined to be a VIE because the public limited partners of VLP (i.e., parties other than entities under common control with the general partner) lack the power to direct the activities of VLP that most significantly impact its economic performance because they do not have substantive kick-out rights over the general partner or substantive participating rights in VLP. Furthermore, we determined that we are the primary beneficiary of VLP because (a) we are the single decision maker and because our general partner interest provides us with the sole power to direct the activities that most significantly impact VLP’s economic performance and (b) our 66.6 percent limited partner interest and 2 percent general partner interest provide us with significant economic rights and obligations. All of VLP’s revenues are derived from us; therefore, there is limited risk to us associated with VLP’s operations.

Diamond Green Diesel Holdings LLC (DGD) is, a joint venture with Darling Green Energy LLC, a subsidiary of Darling Ingredients Inc., that was formed to construct and operate a biodiesel plant that processes animal fats, used cooking oils, and other vegetable oils into renewable green diesel. The plant is located next to our St. Charles Refinery and began operations in June 2013. Our significant agreements with DGD include a debt agreement whereby we financed approximately 60 percent of the construction costs of the plant, an operations agreement that outlines our responsibilities as operator of the plant, and a marketing agreement.

In the event of certain conditions, the debt agreement provides us (as lender) with certain power to direct the activities that most significantly impact DGD’s economic performance. Because the loan agreement conveys such power to us and is separate from our ownership rights, DGD was determined to be a VIE. For this reason and because we hold a 50 percent ownership interest that provides us with significant economic rights and obligations, we determined that we are the primary beneficiary



2011




VALERO ENERGY CORPORATION
CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

of DGD. DGD has risk associated with its operations because it generates revenues from third-party customers.

We also have financial interests in other entities in which we hold a 50 percent ownership interest, which is a significant variable interest. These entities were determined to be VIEs because the entities’ contractual arrangements transfer the power to direct the activities that most significantly impact their economic performance or reduce the exposure to operational variability and risk of loss created by the entity that otherwise would be held exclusively by the equity owners. Furthermore, we determined that we are the primary beneficiary of these VIEs because (a) certain contractual arrangements (exclusive of our ownership rights) provide us with the power to direct the activities that most significantly impact the economic performance of these entities and (b) our 50 percent ownership interests provide us with significant economic rights and obligations. The financial position, results of operations, and cash flows of these VIEs are not material to us.

The VIEs’ assets can only be used to settle their own obligations and the VIEs’ creditors have no recourse to our assets. We do not provide financial guarantees to our VIEs. Although we have provided credit facilities to the VIEs in support of their construction or acquisition activities, these transactions are eliminated in consolidation. Our financial position, results of operations, and cash flows are impacted by our consolidated VIEs’ performance, net of intercompany eliminations, to the extent of our ownership interest in each VIE.

The following tables present summarized balance sheet information for the significant assets and liabilities of our VIEs, which are included in our balance sheets (in millions).

9.SEGMENT INFORMATION

Effective January 1, 2017, we revised our reportable segments to align with certain changes in how our chief operating decision maker manages and allocates resources to our business. Accordingly, we created a new reportable segment — VLP. The results of the VLP segment, which include the results of our majority-owned master limited partnership referred to by the same name, were transferred from the refining segment. Our prior period segment information has been retrospectively adjusted to reflect our current segment presentation.

As a result, we have three reportable segments as follows:
Refining segment includes our refining operations, the associated marketing activities, and certain logistics assets that support our refining operations that are not owned by VLP;
Ethanol segment includes our ethanol operations, the associated marketing activities, and logistics assets that support our ethanol operations; and
VLP segment includes the results of VLP, which provides transportation and terminaling services in support our refining segment.

Operations that are not included in any of the reportable segments are included in the corporate category.

Our reportable segments are strategic business units that offer different products and services. They are managed separately as each business requires unique technologies and marketing strategies. Performance is evaluated based on segment operating income, which includes revenues and expenses that are directly attributable to management of the respective segment. Intersegment sales are generally derived from transactions made at prevailing market rates.

The above changes in current assets and current liabilities differ from changes between amounts reflected in the applicable balance sheets for the respective periods for the following reasons:
the amounts shown above exclude changes in cash and temporary cash investments, deferred income taxes, and current portion of debt and capital lease obligations;

amounts accrued for capital expenditures and deferred turnaround and catalyst costs are reflected in investing activities when such amounts are paid;

amounts accrued for common stock purchases in the open market that are not settled as of the balance sheet date are reflected in financing activities when the purchases are settled and paid; and

certain differences between balance sheet changes and the changes reflected above result from translating foreign currency denominated balances at the applicable exchange rates as of each balance sheet date.

12.11. FAIR VALUE MEASUREMENTS

General
U.S. GAAP requires or permits certain assets and liabilities to be measured at fair value on a recurring or nonrecurring basis in our balance sheets, and those assets and liabilities are presented below under “Recurring Fair Value Measurements” and “Nonrecurring Fair Value Measurements.” Assets and liabilities measured at fair value on a recurring basis, such as derivative financial instruments, are measured at fair value at the end of each reporting period. Assets and liabilities measured at fair value on a nonrecurring basis, such as the impairment of property, plant and equipment, are measured at fair value in particular circumstances.

U.S. GAAP also requires the disclosure of the fair values of financial instruments when an option to elect fair value accounting has been provided, but such election has not been made. A debt obligation is an example of such a financial instrument. The disclosure of the fair values of financial instruments not recognized at fair value in our balance sheet is presented below under “Other Financial Instruments.”

U.S. GAAP provides a framework for measuring fair value and establishes a three-level fair value hierarchy that prioritizes inputs to valuation techniques based on the degree to which objective prices in external active markets are available to measure fair value. Following is a description of each of the levels of the fair value hierarchy.

Level 1 - Observable inputs, such as unadjusted quoted prices in active markets for identical assets or liabilities.
Level 2 - Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active.
Level 3 - Unobservable inputs for the asset or liability. Unobservable inputs reflect our own assumptions about what market participants would use to price the asset or liability. The inputs are developed based on the best information available in the circumstances, which might include occasional market quotes or sales of similar instruments or our own financial data such as internally developed pricing models, discounted cash flow methodologies, as well as instruments for which the fair value determination requires significant judgment.

A description of our assets and liabilities recognized at fair value along with the valuation methods and inputs we used to develop their fair value measurements are as follows:
Commodity derivative contracts consist primarily of exchange-traded futures and swaps, and as disclosed in Note 1312, some of these contracts are designated as hedging instruments. These contracts are measured at fair value using the market approach. Exchange-traded futures are valued based on quoted prices from the exchange and are categorized in Level 1 of the fair value hierarchy. Swaps are priced using third-party broker quotes, industry pricing services, and exchange-traded curves, with appropriate consideration of counterparty credit risk, but because they have contractual terms that are not identical to exchange-traded futures instruments with a comparable market price, these financial instruments are categorized in Level 2 of the fair value hierarchy.
Physical purchase contracts represent the fair value of fixed-price corn purchase contracts. The fair values of these purchase contracts are measured using a market approach based on quoted prices from the commodity exchange or an independent pricing service and are categorized in Level 2 of the fair value hierarchy.
Investments of certain benefit plans consist of investment securities held by trusts for the purpose of satisfying a portion of our obligations under certain U.S. nonqualified benefit plans. The assets categorized in Level 1 of the fair value hierarchy are measured at fair value using a market approach based on quoted prices from national securities exchanges. The assets categorized in Level 3 of the fair value hierarchy represent insurance contracts, the fair value of which is provided by the insurer.

Foreign currency contracts consist of foreign currency exchange and purchase contracts entered into for our international operations to manage our exposure to exchange rate fluctuations on transactions denominated in currencies other than the local (functional) currencies of those operations. These contracts are valued based on quoted prices from the exchange and are categorized in Level 1 of the fair value hierarchy.
Environmental credit obligations represent our liability for the purchase of (i) biofuel credits (primarily Renewable Identification Numbers (RINs) in the U.S.) needed to satisfy our obligation to blend biofuels into the products we produce and (ii) emission credits under the California Global Warming Solutions Act (the California cap-and-trade system, also known as AB 32) and Quebec’s Regulation respecting the cap-and-trade system for greenhouse gas emission allowances (the Quebec cap-and-trade system), (collectively, the cap-and-trade systems). To the degree we are unable to blend biofuels (such as ethanol and biodiesel) at percentages required under the biofuel programs, we must purchase biofuel credits to comply with these programs. Under the cap-and-trade systems, we must purchase emission credits to comply with these systems. These programs are further described in Note 1312 under “Environmental Compliance Program Price Risk.” The liability for environmental credits is based on our deficit for such credits as of the balance sheet date, if any, after considering any credits acquired or under contract, and is equal to the product of the credits deficit and the market price of these credits as of the balance sheet date. The environmental credit obligations are categorized in Level 2 of the fair value hierarchy and are measured at fair value using the market approach based on quoted prices from an independent pricing service.
There were no transfers between levels for assets and liabilities held as of September 30, 2016March 31, 2017 and December 31, 20152016 that were measured at fair value on a recurring basis.

There was no activity during the three and ninethree months ended September 30, 2016March 31, 2017 and 20152016 related to the fair value amounts categorized in Level 3 as of September 30, 2016March 31, 2017 and December 31, 20152016.

Nonrecurring Fair Value Measurements
As discussed in Note 2, we concluded that the Aruba Terminal was impaired as of June 30, 2016, which resulted in an asset impairment loss of $56 million that was recorded in June 2016. The fair value of the Aruba Terminal was determined using an income approach and was classified in Level 3. We employed a probability-weighted approach to possible future cash flow scenarios, including transferring ownership of the business to the GOA or continuing to operate.

There were no assets or liabilities that were measured at fair value on a nonrecurring basis as of September 30, 2016March 31, 2017 and December 31, 20152016.

The methods and significant assumptions used to estimate the fair value of these financial instruments are as follows:
The fair value of cash and temporary cash investments approximates the carrying value due to the low level of credit risk of these assets combined with their short maturities and market interest rates (Level 1).
The fair value of debt is determined primarily using the market approach based on quoted prices provided by third-party brokers and vendor pricing services (Level 2).

13.12.PRICE RISK MANAGEMENT ACTIVITIES

We are exposed to market risks primarily related to the volatility in the price of commodities, and foreign currency exchange rates, and the price of credits needed to comply with various government and regulatory programs. We enter into derivative instruments to manage some of these risks, including derivative instruments related to the various commodities we purchase or produce, and foreign currency exchange and purchase contracts, as described below under “Risk Management Activities by Type of Risk.” These derivative instruments are recorded as either assets or liabilities measured at their fair values (see Note 12)11), as summarized below under “Fair Values of Derivative Instruments,” with changes in fair value recognized currently in income. The effect of these derivative instruments on our income is summarized below under “Effect of Derivative Instruments on Income.”The cash flow effects of all of our derivative instruments are reflected in operating activities in our statements of cash flows for all periods presented.

Risk Management Activities by Type of Risk
Commodity Price Risk
We are exposed to market risks related to the volatility in the price of crude oil, refined petroleum products (primarily gasoline and distillate), grain (primarily corn), soybean oil, and natural gas used in our operations. To reduce the impact of price volatility on our results of operations and cash flows, we use commodity derivative instruments, including futures, swaps, and options. We use the futures markets for the available liquidity, which provides greater flexibility in transacting our hedging and trading operations. We use swaps primarily to manage our price exposure. Our positions in commodity derivative instruments are monitored and managed on a daily basis by our risk control group to ensure compliance with our stated risk management policy that has been approved by our board of directors.

To manage commodity price risk, we use economic hedges, which are not designated as fair value or cash flow hedges, and we use fair value and cash flow hedges from time to time. We also enter into certain commodity derivative instruments for trading purposes. Our objectives for entering into hedges or trading derivatives are described below.

Economic Hedges – Economic hedges represent commodity derivative instruments that are used to manage price volatility in certain (i) feedstock and refined petroleum product inventories, (ii) fixed-price purchase contracts, and (iii) forecasted feedstock, refined petroleum product or natural gas purchases and refined petroleum product sales. The objectives of our economic hedges are to hedge price volatility in certain feedstock and refined petroleum product inventories and to lock in the price of forecasted feedstock, refined petroleum product, or natural gas purchases or refined petroleum product sales at existing market prices that we deem favorable. Economic hedges are not designated as fair value or cash flow hedges for accounting purposes, usually due to the difficulty of establishing the required documentation at the date the derivative instrument is entered into for them to qualify as hedging instruments for accounting purposes.

As of September 30, 2016,March 31, 2017, we had the following outstanding commodity derivative instruments that were used as economic hedges, as well as commodity derivative instruments related to the physical purchase of corn at a fixed price. The information presents the notional volume of outstanding contracts by type of instrument and year of maturity (volumes in thousands of barrels, except those identified as corn contracts that are presented in thousands of bushels and soybean oil contracts that are presented in thousands of pounds).

Foreign Currency Risk
We are exposed to exchange rate fluctuations on transactions entered into by our international operations that are denominated in currencies other than the local (functional) currencies of those operations. To manage our exposure to these exchange rate fluctuations, we use foreign currency exchange and purchase contracts. These contracts are not designated as hedging instruments for accounting purposes and therefore are classified as economic hedges. As of September 30, 2016March 31, 2017, we had forward contracts to purchase $328$350 million of U.S. dollars. These contractscommitments matured on or before October 31, 2016.April 30, 2017.

Environmental Compliance Program Price Risk
We are exposed to market risk related to the volatility in the price of credits needed to comply with various governmental and regulatory environmental compliance programs. To manage this risk, we enter into contracts to purchase these credits when prices are deemed favorable. Some of these contracts are derivative instruments; however, we elect the normal purchase exception and do not record these contracts at their fair values. Certain of these programs require us to blend biofuels into the products we produce, and we are subject to such programs in most of the countries in which we operate. These countries set annual quotas for the percentage of biofuels that must be blended into the motor fuels consumed in these countries. As a producer of motor fuels from petroleum, we are obligated to blend biofuels into the products we produce at a rate that is at least equal to the applicable quota. To the degree we are unable to blend at the applicable rate, we must purchase biofuel credits (primarily RINs in the U.S.). We are exposed to the volatility in the

market price of these credits, and we manage that risk by purchasing biofuel credits when prices are deemed favorable. The cost of meeting our obligations under these compliance programs was $198$146 million and $94$161 million for the three months ended September 30,March 31, 2017 and 2016, and 2015, respectively, and $532 million and $283 million for the nine months ended September 30, 2016 and 2015, respectively. These amounts are reflected in cost of sales.

Effective January 1, 2015, we becameWe are subject to additional requirements under greenhouse gas (GHG) emission programs, including the cap-and-trade systems, as discussed in Note 12.11. Under these cap-and-trade systems, we purchase various greenhouse gasGHG emission credits available on the open market. Therefore, we are exposed to the volatility in the market price of these credits. The cost to implement certain provisions of the cap-and-trade systems are significant; however, we recovered the majority of these costs from our customers for the ninethree months ended September 30,March 31, 2017 and 2016 and 2015 and expect to continue to recover the majority of these costs in the future. For the three and nine months ended September 30,March 31, 2017 and 2016, and 2015, the net cost of meeting our obligations under these compliance programs was immaterial.

Fair Values of Derivative Instruments
The following tables provide information about the fair values of our derivative instruments as of September 30, 2016March 31, 2017 and December 31, 20152016 (in millions) and the line items in the balance sheets in which the fair values are reflected. See Note 1211 for additional information related to the fair values of our derivative instruments.

As indicated in Note 1211, we net fair value amounts recognized for multiple similar derivative contracts executed with the same counterparty under master netting arrangements, including cash collateral assets and obligations. The tables below, however, are presented on a gross asset and gross liability basis, which results in the reflection of certain assets in liability accounts and certain liabilities in asset accounts.

Market and Counterparty Risk
Our price risk management activities involve the receipt or payment of fixed price commitments into the future. These transactions give rise to market risk, which is the risk that future changes in market conditions may make an instrument less valuable. We closely monitor and manage our exposure to market risk on a daily basis in accordance with policies approved by our board of directors. Market risks are monitored by our risk control group to ensure compliance with our stated risk management policy. We do not require any collateral or other security to support derivative instruments into which we enter. We also do not have any derivative instruments that require us to maintain a minimum investment-grade credit rating.

OVERVIEW AND OUTLOOK

Overview
Third Quarter Results
In the third quarter of 2016, weWe reported net income attributable to Valero Energy Corporation (Valero) stockholders of $613$305 million in the first quarter of 2017 compared to $1.4 billion$495 million in the thirdfirst quarter of 2015,2016, which represents a decrease of $764$190 million. Excluding a $42 million (a) tax benefit recognized in connection with the transfer of ownership of the Aruba Refinery and the Aruba Terminal to the Government of Aruba (GOA), adjusted net income attributable to Valero stockholders in the third quarter of 2016 was $571 million, representing aThis decrease of $806 million from the comparable 2015 period. The decrease in net income and adjusted net income attributable to Valero stockholders is primarily due to lower operating income in the thirdfirst quarter of 20162017 compared to the thirdfirst quarter of 20152016 (net of the resulting decrease of $513$105 million in income tax expense between the two periods). Operating income decreased by $1.2 billion, as outlined by segmentwas $537 million in the following table (in millions).

first quarter of 2017 compared to $829 million in the first quarter of 2016, which represents a decrease of $292 million.

The $1.2 billion decrease is due primarily to the following:

Refining segment - The $1.3 billion decrease in operatingOperating income was due primarily to lower margins on refined products and lower discounts on light sweet crude oils and sour crude oils relative to Brent crude oil. This is more fully described on pages 50 and 51.
Ethanol segment - The $71 million increase in operating income was due primarily to higher ethanol margins that resulted from lower corn prices. This is more fully described on page 51.

First Nine Months Results
For the first nine months of 2016, we reported net income attributable to Valero stockholders of $1.9 billion compared to $3.7 billion forin the first nine months of 2015, which represents a decrease of $1.8 billion.

The results for the first nine monthsquarter of 2016 however, arewere positively impacted by (i) a noncash benefit of $579 million (b) from a lower of cost or market inventory valuation adjustmentadjustment. By excluding that benefit from both amounts, adjusted operating income was $536 million and (ii) a noncash charge of $56 millionadjusted net income attributable (a) from an asset impairment loss related to our Aruba Terminal, as well as (iii) a tax benefitValero stockholders was $283 million for the first quarter of $42 million (a) recognized in connection with the transfer of ownership of the Aruba Refinery2016.

The decrease in both net income2017 increased by $1 million and adjusted net income attributable to Valero stockholders is due to lower operating income for the first nine months of 2016 compared to the first nine months of 2015 (net of the resulting decrease of $1.1 billion in income tax expense between the two periods). Operating income decreased by $2.8 billion, while adjusted operating income decreased by $3.5 billion, as outlined by segment in the following tables (in millions).

$22 million, respectively.

The $2.8 billion decrease in operating income was positively impacted by the net effect of the adjustments discussed above for the lower of cost or market inventory valuation benefit and impairment loss. We have excluded such effects from adjusted operating income because we believe that these adjustments are not indicative of our core operating performance and may obscure the underlying business results and trends. The $3.5 billion decrease$1 million increase in adjusted operating incomeis due primarily to the following:

Refining segmentsegment. - The $3.5 billion decrease in adjustedRefining segment operating income wasdecreased by $5 million due primarily to lower margins on other refined products (e.g. petroleum coke, propane, and lower discountssulfur), an increase in charges from the VLP segment related to additional transportation and terminaling services provided by that segment to the refining segment, and higher operating expenses, partially offset by higher margins on light sweet crude oils relative to Brent crude oil.refined petroleum products. This is more fully described on pages 6437 and 65.38.
Ethanol segmentsegment. - The $9 million increase in adjustedEthanol segment operating income wasincreased by $13 million due primarily to lower operating expenses, partially offset by lowerhigher ethanol margins, onwhich improved because of higher ethanol and other co-products.prices. This is more fully described on pages 6538 and 66.39.
VLP segment. VLP segment operating income increased by $27 million due to incremental revenues generated from transportation and terminaling services provided to the refining segment associated with businesses acquired from Valero in 2016 and the acquisition of an undivided interest in crude system assets in January 2017. This is more fully described on page 39.
General and administrative expenses. General and administrative expenses increased by $34 million primarily due to an increase in environmental reserves.

Additional Information and Non-GAAP Reconciliations
Additional details and analysis of the changes in the operating income and adjusted operating income offor our business segments and other components of net income and adjusted net income attributable to Valero stockholders, including a reconciliation of non-GAAP financial measures used in this Overview to their most comparable amountsmeasures reported under U.S.GAAP, are provided below under “RESULTS OF OPERATIONS” beginning on page 41.30.


Effective January 1, 2017, we revised our reportable segments to reflect a new reportable segment — VLP. The results of operations of the VLP segment were previously included in the refining segment. Our prior period segment information has been retrospectively adjusted to reflect our current segment presentation. See Note 9 of Condensed Notes to Consolidated Financial Statements for additional segment information.

RESULTS OF OPERATIONS

The following tables highlight our results of operations, our operating performance, and market prices that directly impact our operations. In addition, these tables include financial measures that are not defined under U.S. GAAP and represent non-GAAP financial measures. These non-GAAP financial measures are reconciled to their most comparable U.S. GAAP financial measures and include adjusted net income attributable to Valero Energy Corporation stockholders, adjusted operating income, and gross margin. In note (c) to these tables, we disclose the reasons why we believe our use of non-GAAP financial measures provides useful information.

Effective January 1, 2017, we revised our reportable segments to align with certain changes in how our chief operating decision maker manages and allocates resources to our business. Accordingly, we created a new reportable segment — VLP. The results of the VLP segment, which include the results of our majority-owned master limited partnership referred to by the same name, were transferred from the refining segment. Our prior period segment information has been retrospectively adjusted to reflect our current segment presentation. The narrative following these tables provides an analysis of our results of operations.

General
Operating revenues decreased $2.9 billion (or 13 percent) and cost of sales decreased $1.6 billion (or 9 percent) in the third quarter of 2016 compared to the third quarter of 2015 primarily due to a decrease in refined product prices and crude oil feedstock costs, respectively. Operating income decreased $1.2 billion in the third quarter of 2016 compared to the third quarter of 2015, primarily due to a decrease in refining segment operating income of $1.3 billion, partially offset by an increase in ethanol segment operating income of $71 million. The reasons for these changes in the operating results of our segments, as well as other items that affected our income, are discussed below.
Refining
Refining segment operating income decreased $1.3 billion in the third quarter of 2016 compared to the third quarter of 2015 primarily due to a $1.4 billion decrease in refining gross margin, partially offset by a $31 million decrease in operating expenses and a $14 million decrease in depreciation and amortization expense.

Refining gross margin decreased $1.4 billion (a $5.31 per barrel decrease) in the third quarter of 2016 compared to the third quarter of 2015, due primarily to the following:

Decrease in gasoline margins - We experienced a decrease in gasoline margins in all of our regions in the third quarter of 2016 compared to the third quarter of 2015. For example, the WTI-based reference margin for U.S. Mid-Continent CBOB gasoline was $14.15 per barrel in the third quarter of 2016 compared to $22.71 per barrel in the third quarter of 2015, representing an unfavorable decrease of $8.56 per barrel. Another example is the ANS-based reference margin for U.S. West Coast CARBOB 87 gasoline that was $17.68 per barrel in the third quarter of 2016 compared to $31.59 per barrel in the third quarter of 2015, representing an unfavorable decrease of $13.91 per barrel. We estimate that the decrease in gasoline margins per barrel in the third quarter of 2016 compared to the third quarter of 2015 had an unfavorable impact to our refining margin of approximately $750 million.

Decrease in distillate margins - We experienced a decrease in distillate margins in all of our regions in the third quarter of 2016 compared to the third quarter of 2015. For example, the Brent-based benchmark reference margin for North Atlantic ultra-low-sulfur diesel was $11.52 per barrel in the third quarter of 2016 compared to $14.54 per barrel in the third quarter of 2015, representing an unfavorable decrease of $3.02 per barrel. Another example is the WTI-based benchmark reference margin for U.S. Mid-Continent ultra-low-sulfur diesel was $15.36 per barrel in the third quarter of 2016 compared to $20.36 per barrel in the third quarter of 2015, representing an unfavorable decrease of $5.00 per barrel. We estimate that the decrease in distillate margins in the third quarter of 2016 compared to the third quarter of 2015 had an unfavorable impact to our refining margin of approximately $320 million.

Lower discounts on light sweet crude oils and sour crude oils - The market prices for refined products generally track the price of Brent crude oil, which is a benchmark sweet crude oil, and we benefit when we process crude oils that are priced at a discount to Brent crude oil, such as WTI crude oil, in periods when pricing terms are favorable. During the third quarter of 2016, we benefited from processing WTI crude oil; however, that benefit declined when compared to the benefit from processing WTI crude oil during the third quarter of 2015. For example, WTI crude oil processed in our U.S. Mid-Continent region sold at a discount of $2.03 per barrel to Brent crude oil in the third quarter of 2016 compared to a discount of $4.73 per barrel in the third quarter of 2015, representing an unfavorable decrease of $2.70 per barrel. Another example is Maya crude oil (a type of sour crude oil) that sold at a discount of $7.88 per barrel to Brent crude oil in the third quarter of 2016 compared to a discount of $8.48 per barrel in the third quarter of 2015, representing an unfavorable decrease of $0.60 per barrel.We estimate that the cost of

Table of Contents

light sweet crude oils and sour crude oils in the third quarter of 2016 had an unfavorable impact to our refining margin of approximately $180 million.

Higher costs of biofuel credits - As more fully described in Note 13 of Notes to Consolidated Financial Statements, we must purchase biofuel credits in order to meet our biofuel blending obligation under various government and regulatory compliance programs, and the cost of these credits (primarily RINs in the U.S.) increased by $104 million from $94 million in the third quarter of 2015 to $198 million in third quarter of 2016. This increase was due to an increase in the market price of RINs caused by an expected shortage in the market of available RINs.

The decrease of $31 million in operating expenses was primarily due to a $20 million decrease in employee-related expenses primarily due to lower incentive compensation expense.

The decrease of $14 million in depreciation and amortization expense was primarily due to $17 million of write-offs for projects that were cancelled during the third quarter of 2015.

Ethanol
Ethanol segment operating income increased $71 million in the third quarter of 2016 compared to the third quarter of 2015 primarily due to a $64 million (or $0.19 per gallon) increase in gross margin and a $9 million reduction in operating expenses.

The increase in ethanol segment gross margin of $64 million was due primarily to the following:

Lower corn prices - Corn prices were lower in the third quarter of 2016 compared to the third quarter of 2015 primarily due to higher forecasted yields from the current corn crop in the corn-producing regions of the U.S. Mid-Continent. For example, the Chicago Board of Trade corn price was $3.32 per bushel in the third quarter of 2016 compared to $3.83 per bushel in the third quarter of 2015. We estimate that the decrease in the price of corn that we processed during the third quarter of 2016 had a favorable impact to our ethanol margin of approximately $70 million.

Lower co-product prices - A decrease in export demand had an unfavorable effect on the prices we received for corn-related co-products, primarily distillers grains. We estimate that the decrease in distillers grain prices had an unfavorable impact to our ethanol margin of approximately $8 million.

The $9 million decrease in operating expenses was primarily due to a $5 million decrease in chemical costs.

Other
Income tax expense decreased $513 million from the third quarter of 2015 to the third quarter of 2016 primarily as a result of lower income before income tax expense. The effective tax rates of 18 percent in the third quarter of 2016 and 32 percent in the third quarter of 2015 are lower than the U.S. statutory rate of 35 percent because income from our international operations is taxed at statutory rates that are lower than in the U.S. The effective tax rate in the third quarter of 2016 was also lower than the rate in the third quarter of 2015 due to (i) a benefit of $42 million associated with the transfer of ownership of the Aruba Refinery and Aruba Terminal to the GOA and (ii) a benefit of $35 million resulting from the settlement of an income tax audit. The transfer of ownership of the Aruba Refinery and Aruba Terminal to the GOA is more fully described in Note 2 of Condensed Notes to Consolidated Financial Statements.

The following notes relate to references on pages 4130 through 49 and pages 52 through 61.34.
(a)
In accordance with U.S. GAAP, we are required to state our inventories at the lower of cost or market. When the market price of our inventory falls below cost, we record a lower of cost or market inventory valuation adjustment to write down the value to market. In subsequent periods, the value of our inventory is reassessed and a lower of cost or market inventory valuation adjustment is recorded to reflect the net change in the lower of cost or market inventory valuation reserve between periods. As of September 30, 2016, the market price of our inventory was above cost; therefore, we did not have a lower of cost or market inventory valuation reserve as of that date. During the ninethree months ended September 30,March 31, 2016, we recorded a change in our lower of cost or market inventory valuation reserve that was established on December 31, 2015, resulting in a noncash benefit of $747$293 million of which $697($263 million and $50$30 million were attributable to our refining segment and ethanol segment, respectively.segments, respectively). This adjustment is further discussed in Note 32 of Condensed Notes to Consolidated Financial Statements.

(b)Effective October 1,The VLP segment information for the three months ended March 31, 2016 we (i) transferred ownership of all of our assets in Aruba, other than certain hydrocarbon inventories and working capital,has been retrospectively adjusted for VLP’s acquisitions that occurred subsequent to Refineria di Aruba N.V. (RDA), an entity wholly-owned by the GOA, (ii) settled our obligations under various agreements with the GOA, including agreements that required us to dismantle our leasehold improvements under certain conditions, and (iii) sold the working capital of our Aruba operations, including hydrocarbon inventories, to the GOA, CITGO Aruba Refining N.V. (CAR), and CITGO Petroleum Corporation (together with CAR and certain other affiliates, collectively, CITGO). We refer to this transaction as the “Aruba Disposition.”March 31, 2016.

In June 2016, we recognized an asset impairment loss of $56 million representing all of the remaining carrying value of the long-lived assets of our crude oil and refined products terminal and transshipment facility in Aruba (collectively, the Aruba Terminal). We recognized the impairment loss at that time because we concluded that it was more likely than not that we would ultimately transfer ownership of these assets to the GOA as a result of agreements entered into in June 2016 between the GOA and CITGO for the GOA’s lease of those assets to CITGO. There was no other significant effect to our results of operations from the Aruba Disposition during the three and nine months ended September 30, 2016, except with respect to income taxes, which are discussed below. In addition, the net cash impact to us upon effectiveness of the Aruba Disposition on October 1, 2016, was not significant.

In September 2016 and in connection with the Aruba Disposition, our U.S. subsidiaries were unable to collect any outstanding debt obligations owed to them by our Aruba subsidiaries, which resulted in the recognition by us of an income tax benefit in the U.S. of $42 million during the three and nine months ended September 30, 2016. We had no income tax effect in Aruba from the cancellation of debt or other effects of the Aruba Disposition because of net operating loss carryforwards associated with our operations in Aruba against which we had previously recorded a full valuation allowance.

(c)
We use certain financial measures (as noted below) that are not defined under U.S.GAAP and are considered to be non-GAAP measures.

We have defined these non-GAAP measures and believe they are useful to the external users of our financial statements, including industry analysts, investors, lenders, and rating agencies. We believe these measures are useful to assess our ongoing financial performance because, when reconciled to their most comparable U.S.GAAP measures, they provide improved comparability between periods through the exclusion of certain items that we believe are not indicative of our core operating performance and that may obscure our underlying business results and trends. These non-GAAP measures should not be considered as alternatives to their most comparable U.S.GAAP measures nor should they be considered in isolation or as a substitute for an analysis of our results of operations as reported under U.S.GAAP. In addition, these non-GAAP measures may not be comparable to similarly titled measures used by other companies because we may define them differently, which diminishes the utility of these measures.

Non-GAAP measures are as follows:

Adjusted net income attributable to Valero Energy Corporation stockholders is defined as net income attributable to Valero Energy Corporation stockholders excluding the lower of cost or market inventory valuation adjustment and its related income tax effect.

(h)Average market reference prices for LLS crude oil, along with price differentials between the price of LLS crude oil and other types of crude oils are reflected without adjusting for the impact of the futures pricing for the corresponding delivery month. Therefore, the prices reported reflect the prompt month pricing only, without an adjustment for futures pricing (known in the industry as the Calendar Month Average (CMA) “roll” adjustment). We previously had provided average market reference prices that included the CMA “roll” adjustment. Accordingly, the average market reference price and price differentials for LLS crude oil for the three and nine months ended September 30, 2015March 31, 2016 have been adjusted to conform to the current presentation.

(i)(h)Average market reference price differentials to Mars crude oil have been replaced by average market reference price differentials to Argus Sour Crude Index (ASCI).ASCI crude oil. Mars crude oil is one of the three grades of sour crude oil used to create ASCI crude oil, and therefore, ASCI crude oil is a more comprehensive price marker for medium sour crude oil. Accordingly, the price differentials for ASCI crude oil for the three and nine months ended September 30, 2015March 31, 2016 are included to conform to the current presentation.

General
Operating revenues decreased $14.1 billion (or 20 percent) and cost of sales decreased $10.6 billion (or 18 percent) in the first nine months of 2016 compared to the first nine months of 2015 primarily due to a decrease in refined product prices and crude oil feedstock costs, respectively. Operating income decreased $2.8 billion in the first nine months of 2016 compared to the first nine months of 2015, primarily due to a decrease in refining segment operating income of $2.8 billion, partially offset by an increase in ethanol segment operating income of $59 million. Adjusted operating income decreased $3.5 billion in the first nine months of 2016 compared to the first nine months of 2015, primarily due to a decrease in refining segment

Table of Contents

adjusted operating incomeTotal Company, Corporate, and Other
Operating revenues increased $6.1 billion and cost of $3.5 billion, partially offset by an increase in ethanol segment adjusted operating income of $9 million. The reasons for these changes in the operating results of our segments, as well as other items that affected our income, are discussed below.
Refining
Refining segment adjusted operating income decreased $3.5sales increased $5.9 billion in the first nine monthsquarter of 20162017 compared to the first nine monthsquarter of 20152016 due primarily to increases in refined petroleum product prices and crude oil feedstock costs, respectively, associated with our refining segment, reflecting improved product margins of $137 million. This $137 million improvement was more than offset by the effect from the $293 million benefit in the first quarter of 2016 from the lower of cost or market inventory valuation adjustment and increases in operating expenses, general and administrative expenses, and depreciation and amortization expense of $87 million, $34 million, and $15 million, respectively, resulting in a decrease in operating income of $292 million. This decrease in operating income is the primary driver of the $190 million decrease in net income attributable to Valero stockholders from $495 million in the first quarter of 2016 to $305 million in the first quarter of 2017.

Excluding the $293 million benefit from the lower of cost or market inventory valuation adjustment, first quarter 2016 adjusted operating income was $536 million. Compared to this adjusted amount, operating income increased by $1 million in the first quarter of 2017 to $537 million, with improved product margins being almost fully offset by the increased costs discussed above. Details regarding changes in product margins, operating expenses, and depreciation and amortization expense are discussed by segment in the individual segment analysis below.

General and administrative expenses increased $34 million in the first quarter of 2017 compared to the first quarter of 2016 primarily due to an increase in environmental reserves.

Income tax expense decreased $105 million from the first quarter of 2016 to the first quarter of 2017 primarily as a $3.5result of lower income before income tax expense. The effective tax rates of 26 percent in the first quarter of 2017 and 30 percent in the first quarter of 2016 are lower than the U.S. statutory rate of 35 percent because income from our international operations is taxed at statutory rates that are lower than in the U.S. The effective tax rate in the first quarter of 2017 was also lower than the rate in the first quarter of 2016 due to a reduction in the statutory tax rate in Quebec and from the favorable resolution of several state income tax audits.

Refining Segment Results
Refining segment operating revenues increased $6.0 billion and cost of sales increased $5.9 billion in the first quarter of 2017 compared to the first quarter of 2016 primarily due to an increase in refined petroleum product prices and crude oil feedstock costs, respectively, reflecting improved product margins (refining gross margin) of $72 million. This $72 million improvement was more than offset by the effect from the $263 million benefit in the first quarter of 2016 from the lower of cost or market inventory valuation adjustment and an increase in operating expenses of $77 million, resulting in a decrease in operating income of $268 million. Excluding the $263 million benefit from the lower of cost or market inventory valuation adjustment, first quarter 2016 adjusted operating income for the refining segment was $652 million. Compared to this adjusted amount, operating income decreased by $5 million in the first quarter of 2017 to $647 million, with the $72 million increase in refining gross margin and a $63being more than offset by the $77 million increase in depreciation and amortization expense, partially offset by a $97 million decrease in operating expenses.

Refining gross margin decreased $3.5 billionincreased $72 million (a $4.87$0.48 per barrel decrease)increase) in the first nine monthsquarter of 20162017 compared to the first nine monthsquarter of 2015,2016, primarily due primarily to the following:

DecreaseIncrease in distillate marginsmargins. - We experienced a decreasean increase in distillate margins throughout all of our regions in the first nine monthsquarter of 20162017 compared to the first nine monthsquarter of 2015.2016. For example, the Brent-based benchmark reference margin for U.S. Gulf Coast ultra-low-sulfur diesel was $9.34$11.12 per barrel in the first nine monthsquarter of 20162017 compared to $13.76$7.92 per barrel in the first nine monthsquarter of 2015,2016, representing an unfavorable decreasea favorable

increase of $3.20 per barrel. Another example is the WTI-based benchmark reference margin for U.S. Mid-Continent ultra-low-sulfur diesel that was $12.70$13.99 per barrel in the first nine monthsquarter of 20162017 compared to $20.36$11.03 per barrel in the first nine monthsquarter of 2015,2016, representing an unfavorable decreasea favorable increase of $7.66$2.96 per barrel. We estimate that the decreaseincrease in distillate margins per barrel in the first nine monthsquarter of 20162017 compared to the first nine monthsquarter of 20152016 had an unfavorablea favorable impact to our refining margin of approximately $1.6 billion.

Decrease in gasoline margins - We experienced a decrease in gasoline margins throughout all of our regions during the first nine months of 2016 compared to the first nine months of 2015. For example, the ANS-based reference margin for U.S. West Coast CARBOB 87 gasoline was $18.86 per barrel in the first nine months of 2016 compared to $27.21 per barrel during the first nine months of 2015, representing an unfavorable decrease of $8.35 per barrel. Another example is the Brent-based benchmark reference margin for U.S. Gulf Coast CBOB gasoline that was $9.54 per barrel in the first nine months of 2016 compared to $10.95 per barrel during the first nine months of 2015, representing an unfavorable decrease of $1.41 per barrel.We estimate that the decrease in gasoline margins per barrel during the first nine months of 2016 compared to the first nine months of 2015 had an unfavorable impact to our refining margin of approximately $1.2 billion.
$244 million.

Lower discounts on light sweet crude oils and sour crude oils - The market prices for refined products generally track the price of Brent crude oil, which is a benchmark sweet crude oil, and we benefit when we process crude oils that are priced at a discount to Brent crude oil, such as WTI crude oil, in periods when pricing terms are favorable. During the first nine months of 2016, we benefited from processing WTI crude oil; however, that benefit declined compared to the benefit from processing WTI crude oil during the first nine months of 2015. For example, WTI crude oil processed in our U.S. Mid-Continent region sold at a discount of $1.80 per barrel to Brent crude oil in the first nine months of of 2016 compared to a discount of $5.66 per barrel in the first nine months of of 2015, representing an unfavorable decrease of $3.86 per barrel. Another example is Maya crude oil (a type of sour crude oil) that sold at a discount of $8.73 per barrel to Brent crude oil during the first nine months of 2016 compared to a discount of $9.24 per barrel during the first nine months of 2015, representing an unfavorable decrease of $0.51 per barrel. We estimate that the cost of light sweet crude oils and sour crude oils during the first nine months of 2016 had an unfavorable impact to our refining margin of approximately $720 million.

Higher costs of biofuel creditscredits. - As more fully described in Note 1312 of Condensed Notes to Consolidated Financial Statements, we must purchase biofuel credits in order to meet our biofuel blending obligation under various government and regulatory compliance programs, and the cost of these credits (primarily RINs in the U.S.) increaseddecreased by $249$15 million from $283$161 million in the first nine monthsquarter of 20152016 to $532$146 million in the first nine monthsquarter of 2016.2017. This increasedecrease was due to a decrease in the market price of RINs.

Decrease in other refined product margins. We experienced a decrease in the margins of other refined products (such as petroleum coke and sulfur) relative to Brent crude oil in the first quarter of 2017 compared to the first quarter of 2016 due to an increase in the cost of crude oils between the periods. Because the market prices for our other refined products remain relatively stable, our margins decline when the cost of crude oils that we process increases. For example, the benchmark price of RINs caused by an expected shortageBrent crude oil was $54.65 in the marketfirst quarter of available RINs.2017 compared to $35.14 in the first quarter of 2016, an increase of $19.51. We estimate that the decrease in other refinery products margins per barrel in the first quarter of 2017 compared to the first quarter of 2016 had an unfavorable impact of $130 million.

HigherLower throughput volumesvolumes. - Refining throughput volumes increaseddecreased by 74,00041,000 barrels per day in the first nine monthsquarter of 2016 compared to the first nine months of 2015.2017. We estimate that the increasedecrease in refining throughput volumes had a positivenegative impact on our refining margin of approximately $175$30 million.

The decrease of $97
Increase in charges from VLP. Charges from the VLP segment for transportation and terminaling services increased $27 million in the first quarter of 2017 compared to the first quarter of 2016 primarily due to new charges from businesses acquired by VLP after the first quarter of 2016. Details regarding the increase in charges from VLP are discussed in the VLP segment analysis below.

The increase of $77 million in refining segment operating expenses was primarily due to a $58$38 million decreaseincrease in energy costs driven by lowerhigher natural gas prices ($2.272.95 per MMBtu in the first nine monthsquarter of 20162017 compared to $2.73$1.93 per MMBtu in the first nine monthsquarter of 2015)2016) and a $26$27 million decreaseincrease in employee-related expenses primarily due to lower incentive compensation expense.costs associated with maintenance activities in the first quarter of 2017.

The increaseEthanol Segment Results
Ethanol segment operating revenues increased $117 million and cost of $63sales increased $79 million in depreciation and amortization expense wasthe first quarter of 2017 compared to the first quarter of 2016 primarily due to an increase in ethanol prices and corn costs, respectively, reflecting improved product margins (ethanol gross margin) of $41$38 million. This $38 million in depreciation expense associated with new capital projects andimprovement was more than offset by the effect from the $30 million benefit in refinery turnaroundthe first quarter of 2016 from the lower of cost or market inventory valuation adjustment and catalystincreases in operating expenses and depreciation and amortization expense of $10 million and $15 million, respectively, resulting in a decrease in operating income of $17 million. Excluding the $30 million benefit from the completionlower of turnaround projects at several of our refineries.

Ethanol

Compared to this adjusted amount, operating income increased $9by $13 million in the first nine monthsquarter of 2016 compared2017 to $22 million, with the first nine months of 2015 primarily due to a $39increase in ethanol gross margin being partially offset by the $10 million decreaseincrease in operating expenses partially offset by a $16and the $15 million increase in depreciation and amortization expense and a $14 million (or $0.01 per gallon) decrease in gross margin.expense.

The decreaseincrease in ethanol segment gross margin of $14$38 million (or $0.08 per gallon) was primarily due primarily to the following:

Lowerhigher ethanol prices -prices. Ethanol prices were lowerhigher in the first nine monthsquarter of 2016 primarily due to the decrease in crude oil and gasoline prices in the first nine months of 20162017 compared to the first nine monthsquarter of 2015.2016 driven by increased ethanol demand. For example, the New York Harbor ethanol price was $1.55$1.58 per gallon in the first nine monthsquarter of 20162017 compared to $1.59$1.45 per gallon in the first nine monthsquarter of 2015.2016. We estimate that the decreaseincrease in the price of ethanol per gallon during the first nine monthsquarter of 2016 had an unfavorable impact to our ethanol margin of approximately $30 million.
Lower co-product prices - A decrease in export demand had an unfavorable effect on the prices we received for corn-related co-products, primarily distillers grains. We estimate that the decrease in distillers grain prices had an unfavorable impact to our ethanol margin of approximately $60 million.

Lower corn prices - Corn prices were lower in the first nine months of 2016 compared to the first nine months of 2015 primarily due to higher forecasted yields from the current corn crop in the corn-producing regions of the U.S. Mid-Continent. For example, the CBOT corn price was $3.62 per bushel in the first nine months of 2016 compared to $3.78 per bushel in the first nine months of 2015. We estimate that the decrease in the price of corn that we processed during the first nine months of 20162017 had a favorable impact to our ethanol margin of approximately $65$35 million.

The increase of $16$15 million in ethanol segment depreciation and amortization expense was primarily due to a $10 million gain on the sale of certain plantwrite-offs for assets that were idled in the first nine monthsquarter of 2015 that was reflected in depreciation and amortization expense thereby reducing depreciation and amortization expense in that period.2017.

OtherVLP Segment Results
In June 2016, we evaluated the Aruba Terminal for potential impairment and concluded that it was impaired, resultingVLP segment operating revenues increased $27 million in an asset impairment loss of $56 million related to our refining segment. This matter is more fully described in Note 2 of Condensed Notes to Consolidated Financial Statements.

Income tax expense decreased $1.1 billion from the first nine monthsquarter of 20152017 compared to the first nine monthsquarter of 2016 primarily due to incremental revenues generated from transportation and terminaling services provided to the refining segment associated with businesses and assets acquired after the first quarter of 2016, as a resultdiscussed below. This $27 million increase in revenues resulted in an increase in operating income of lower income before income tax expense. The effective tax rates of 25 percent$27 million.

VLP segment operating revenues increased $27 million in the first nine monthsquarter of 2017 compared to the first quarter of 2016, and 32primarily due to the following:

Incremental terminaling throughput from acquired businesses. VLP experienced a 38 percent increase in terminaling revenues in the first nine monthsquarter of 2015 are lower than2017 compared to the U.S. statutory ratefirst quarter of 35 percent because income2016 generated by contributions from our international operations is taxed at statutory rates that are lower thanthe McKee Terminal Services and the Meraux and Three Rivers Terminal Services Businesses, which were acquired by VLP from Valero in the U.S. The effective tax rate in the first nine monthssecond and third quarters of 2016, was also lower than the rate in the firstrespectively. The incremental throughput volumes generated at these terminals had a favorable impact to VLP’s operating revenues of $23 million.

LIQUIDITY AND CAPITAL RESOURCES

Cash Flows for the NineThree Months Ended September 30,March 31, 20162017
Our operations generated $3.8 billion$988 million of cash in the first ninethree months of 2017, driven primarily by net income of $321 million, noncash charges to income of $496 million, and a positive change in working capital of $151 million. Noncash charges primarily include $500 million of depreciation and amortization expense. See “RESULTS OF OPERATIONS” for further discussion of our operations. The change in our working capital is further detailed in Note 10 of Condensed Notes to Consolidated Financial Statements. This source of cash mainly resulted from:
a decrease in receivables, partially offset by a decrease in accounts payable, primarily as a result of the timing of collections of receivables and payments of invoices, respectively; and
an increase in inventory volumes held.

The $988 million of cash generated by our operations, along with (i) net proceeds of $35 million from VLP’s sale of common units representing limited partner interests to the public and (ii) $353 million from available cash on hand, were used mainly to:
fund $641 million in capital investments, which include capital expenditures, deferred turnaround and catalyst costs, and equity-method joint venture investments;
acquire an undivided interest in crude system assets for $72 million;
purchase common stock for treasury of $314 million;
pay common stock dividends of $315 million; and
pay distributions to noncontrolling interests of $34 million.

Cash Flows for the Three Months Ended March 31, 2016
Our operations generated $640 million of cash in the first three months of 2016, driven primarily by net income of $2.0 billion$513 million and excluding $928 million ofnet noncash charges to income along with a positive change in working capital of $953$313 million. Noncash charges include $1.4 billion$485 million of depreciation and amortization expense $56 million for the asset impairment loss associated with our Aruba Terminal, and $193$121 million of deferred income tax expense, partially offset by a benefit of $747$293 million from a lower of cost or market inventory valuation adjustment. See “RESULTS OF OPERATIONS” for further discussion of our operations. TheHowever, the change in our working capital is further detailedin the first three months of 2016 had a negative impact to cash generated by our operations of $177 million as shown in Note 1110 of Condensed Notes to Consolidated Financial Statements. This sourceuse of cash mainly resulted from:
an increasethe prepayment of certain expenses, primarily for the purchase of emissions credits related to cap-and-trade systems at prices we deemed favorable in accounts payable, partially offset by an increase in receivables, primarily as a resultanticipation of increasing commodity prices;our annual obligation;
the payment of accrued incentive compensation related to 2015;
payments of sales, excise, and ad valorem taxes; and
the temporary reductionpartial liquidation of our inventories.

The $3.8 billion$640 million of cash generated by our operations, along with $1.65 billion in proceeds$336 million from the issuance of debt (primarily $1.25 billion of 3.4 percent senior notes due September 15, 2026 and borrowings under the VLP Revolver of $349 million as discussed in Note 4 of Condensed Notes to Consolidated Financial Statements),our total cash on hand, were used mainly to:
fund $1.4 billion$479 million in capital investments, which include capital expenditures, deferred turnaround and catalyst costs, and equity-method joint venture investments;
pay off a long-term liability of $137 million owed to a joint venture partner for an owner-method joint venture investment;
purchase common stock for treasury of $1.2 billion;$265 million; and
pay common stock dividends of $840 million;
pay distributions of $54 million to noncontrolling interests; and
increase available cash on hand by $1.8 billion.

Cash Flows for the Nine Months Ended September 30, 2015
Our operations generated $5.1 billion of cash in the first nine months of 2015, driven primarily by net income of $3.7 billion and excluding $1.4 billion of noncash charges to income. Noncash charges include $1.3 billion of depreciation and amortization expense and $77 million of deferred income tax expense. See “RESULTS OF OPERATIONS” for further discussion of our operations. The change in our working capital in the first nine months of 2015 had little impact to cash generated by our operations, contributing only $46$282 million. The change in our working capital is further detailed in Note 11 of Condensed Notes to Consolidated Financial Statements. This source of cash mainly resulted from a decrease in receivables, partially offset by a decrease in accounts payable, primarily as a result of decreasing commodity prices.

The $5.1 billion of cash generated by our operations in the first nine months of 2015, along with $1.45 billion in proceeds from the issuance of debt ($600 million of 3.65 percent senior notes due March 15, 2025, $650 million of 4.9 percent senior notes due March 15, 2045, and borrowings under the VLP Revolver of $200 million as discussed in Note 4 of Condensed Notes to Consolidated Financial Statements), were used mainly to:
fund $1.7 billion in capital investments, which include capital expenditures, deferred turnaround and catalyst costs, and equity-method joint venture investments;
make debt repayments of $509 million, of which $400 million related to our 4.5 percent senior notes, $75 million related to our 8.75 percent debentures, $25 million related to the VLP Revolver, and $9 million related to other non-bank debt and capital lease obligations;
purchase common stock for treasury of $2.1 billion;

Capital Investments
For 2016,2017, we expect to incur approximately $2.4$2.7 billion for capital investments, including capital expenditures, deferred turnaround and catalyst costs, and equity-method joint venture investments. This consists of approximately $1.5$1.6 billion for stay-in-business capital and $900 million$1.1 billion for growth strategies,

including our continued investment in Diamond Pipeline LLC (Diamond Pipeline) described below. This capital investment estimate excludes potential strategic acquisitions. We continuously evaluate our capital budget and make changes as conditions warrant.

We hold equity-method investments in joint ventures and we invest in these joint ventures or enter into new joint venture arrangements to enhance our operations. In December 2015, we exercised our option to purchaseWe have a 50 percent interest in Diamond Pipeline, which was formed by Plains All American Pipeline, L.P. (Plains) to construct and operate a 440-mile, 20-inch crude oil pipeline expected to provide capacity of up to 200,000 barrels per day of domestic sweet crude oil from the PlainsPlains’ Cushing, Oklahoma terminal to our Memphis Refinery, with the ability to connect into the Capline Pipeline. The pipeline is expected to be completed in 2017 for an estimated cost of $925 million. We have contributed $136made cumulative cash contributions of $252 million in Diamond Pipeline and expect to continue making contributions as the construction progresses.

Contractual Obligations
As of September 30, 2016,March 31, 2017, our contractual obligations included debt, capital lease obligations, operating leases, purchase obligations, and other long-term liabilities. There were no material changes outside the ordinary course of business with respect to these contractual obligations during the ninethree months ended September 30, 2016. In October 2016,March 31, 2017. However, in the ordinary course of business, we entered into agreements under which we expect to lease storage tanks located at three of our refineries. The leases will not commence until certain required regulatory permitting occurs. The lease agreements will be accounted for as capital leases and we expect to recognizerecognized capital lease assets and related obligations of approximately $490 million.million each related to the lease of storage tanks located at three of our refineries. These capital lease agreements have initial terms of 10 years each and each agreement haswith successive 10-year automatic renewal terms.

Currently, we have an accounts receivable sales facility with a group of third-party entities and financial institutions to sell eligible trade receivables on a revolving basis up to $1.3 billion. As of September 30, 2016, the actual availability under the facility fell below the facility borrowing capacity to $1.2 billion primarily due to a decrease in eligible trade receivables as a result of the current market price environment for the finished products that we produce.

Our debt and financing agreements do not have rating agency triggers that would automatically require us to post additional collateral. However, in the event of certain downgrades of our senior unsecured debt by the ratings agencies, the cost of borrowings under some of our bank credit facilities and other arrangements would increase. All of theour ratings on our senior unsecured debt are at or above investment grade level as follows:

We cannot provide assurance that these ratings will remain in effect for any given period of time or that one or more of these ratings will not be lowered or withdrawn entirely by a rating agency. We note that these credit ratings are not recommendations to buy, sell, or hold our securities and may be revised or withdrawn at any time by the rating agency. Each rating should be evaluated independently of any other rating. Any future reduction below investment grade or withdrawal of one or more of our credit ratings could have a material adverse impact on our ability to obtain short- and long-term financing and the cost of such financings.

Other Matters Impacting Liquidity and Capital Resources
Stock Purchase Program
As of September 30, 2016, we had approximately $190 million of our common stock remaining to be purchased under our previously authorized $2.5 billion common stock purchase program. On September 21, 2016, our board of directors authorized our purchase of up to an additional $2.5 billion of our outstanding common stock (the 2016 program) with no expiration date. This authorization was in addition to the remaining amount available under a $2.5 billion program authorized on July 13, 2015 (the 2015 program). During the first quarter of 2017, we completed our purchases under the 2015 program. As of March 31, 2017, we had approximately $2.2 billion remaining available under the 2016 program. We have no obligation to make purchases under thethis program.

Pension Plan Funding
We contributed $132plan to contribute approximately $28 million to our pension plans and $12$19 million to our other postretirement benefit plans during the nine months ended September 30, 2016. During the fourth quarter of 2016, we plan to contribute approximately $4 million to our pension plans and $8 million to our other postretirement benefit plans.2017.

Environmental Matters
Our operations are subject to extensive environmental regulations by governmental authorities relating to the discharge of materials into the environment, waste management, pollution prevention measures, GHG emissions, and characteristics and composition of gasolines and distillates. Because environmental laws and regulations are becoming more complex and stringent and new environmental laws and regulations are continuously being enacted or proposed, the level of future expenditures required for environmental matters could increase in the future as previously discussed above in “OUTLOOK.” In addition, any major upgrades in any of our operating facilities could require material additional expenditures to comply with environmental



69

Table of Contents

laws and regulations. See Note 54 of Condensed Notes to Consolidated Financial Statements for a further discussion of our environmental matters.

Tax Matters
During the third quarter of 2016, we settled the audit related to our U.S. federal income tax returns for 2008 and 2009. The Internal Revenue Service (IRS) has ongoing tax audits related to our U.S. federal income tax returns from 2010 through 2014,2015, and we have received Revenue Agent Reports (RARs) in connection with the 2010 and 2011 audit. We are contesting certain tax positions and assertions included in the RARs and continue to



42

Table of Contents

make progress in resolving certain of these matters with the IRS. We believe that the ultimate settlement of these audits will not be material to our financial position, results of operations, or liquidity.

Cash Held by Our International Subsidiaries
We operate in countries outside the U.S. through subsidiaries incorporated in these countries, and the earnings of these subsidiaries are taxed by the countries in which they are incorporated. We intend to reinvest these earnings indefinitely in our international operations even though we are not restricted from repatriating such earnings to the U.S. in the form of cash dividends. Should we decide to repatriate such earnings, we would incur and pay taxes on the amounts repatriated. In addition, such repatriation could cause us to record deferred tax expense that could significantly impact our results of operations. We believe, however, that a substantial portion of our international cash can be returned to the U.S. without significant tax consequences through means other than a repatriation of earnings. As of September 30, 2016, $2.2March 31, 2017, $2.5 billion of our cash and temporary cash investments was held by our international subsidiaries.

Concentration of Customers
Our operations have a concentration of customers in the refining industry and customers who are refined petroleum product wholesalers and retailers. These concentrations of customers may impact our overall exposure to credit risk, either positively or negatively, in that these customers may be similarly affected by changes in economic or other conditions. However, we believe that our portfolio of accounts receivable is sufficiently diversified to the extent necessary to minimize potential credit risk. Historically, we have not had any significant problems collecting our accounts receivable.

Sources of Liquidity
We believe that we have sufficient funds from operations and, to the extent necessary, from borrowings under our credit facilities, to fund our ongoing operating requirements. We expect that, to the extent necessary, we can raise additional funds from time to time through equity or debt financings in the public and private capital markets or the arrangement of additional credit facilities. However, there can be no assurances regarding the availability of any future financings or additional credit facilities or whether such financings or additional credit facilities can be made available on terms that are acceptable to us.

CRITICAL ACCOUNTING POLICIESESTIMATES

The preparation of financial statements in conformity with U.S.GAAP requires us to make estimates and assumptions that affect the amounts reported in our financial statements and accompanying notes. Actual results could differ from those estimates. As of September 30, 2016March 31, 2017, there were no significant changes to our critical accounting policies since the date our annual report on Form 10‑K for the year ended December 31, 20152016 was filed.

ItemITEM 3.Quantitative and Qualitative Disclosures About Market RiskQUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

COMMODITY PRICE RISK

We are exposed to market risks related to the volatility in the price of crude oil, refined petroleum products (primarily gasoline and distillate), grain (primarily corn), soybean oil, and natural gas used in our operations. To reduce the impact of price volatility on our results of operations and cash flows, we use commodity derivative instruments, including swaps, futures, and options to manage the volatility of:
inventories and firm commitments to purchase inventories generally for amounts by which our current year inventory levels (determined on a last-in, first-out (LIFO)LIFO basis) differ from our previous year-end LIFO inventory levels, and
forecasted feedstock and refined petroleum product purchases, refined petroleum product sales, natural gas purchases, and corn purchases to lock in the price of those forecasted transactions at existing market prices that we deem favorable.

We use the futures markets for the available liquidity, which provides greater flexibility in transacting our price risk activities. We use swaps primarily to manage our price exposure. We also enter into certain commodity derivative instruments for trading purposes to take advantage of existing market conditions related to future results of operations and cash flows.

Our positions in commodity derivative instruments are monitored and managed on a daily basis by our risk control group to ensure compliance with our stated risk management policy that has been approved by our board of directors.

COMPLIANCE PROGRAM PRICE RISK

We are exposed to market risk related to the volatility in the price of biofuel credits and GHG emission credits needed to comply with various governmental and regulatory programs. To manage these risks, we enter into contracts to purchase these credits when prices are deemed favorable. Some of these contracts are derivative instruments; however, we elect the normal purchase exception and do not record these contracts at their fair values. As of September 30, 2016March 31, 2017, there was an immaterial amount of gain or loss in the fair value of derivative instruments that would result from a 10 percent increase or decrease in the underlying price of the contracts. See Note 1312 of Condensed Notes to Consolidated Financial Statements for a discussion about these compliance programs.

Item 1A. Risk Factors
ITEM 1A.RISK FACTORS

We disclose the following risk factor in addition toThere have been no changes from the risk factors we have disclosed in our annual report on Form 10-K for the year ended December 31, 2015.2016.

Compliance with the U.S. Environmental Protection Agency Renewable Fuel Standard could adversely affect our performance.

The U.S. Environmental Protection Agency (EPA) has implemented a Renewable Fuel Standard (RFS) pursuant to the Energy Policy Act of 2005 and the Energy Independence and Security Act of 2007. The RFS program sets annual quotas for the quantity of renewable fuels (such as ethanol) that must be blended into transportation fuels consumed in the United States. A Renewable Identification Number (RIN) is assigned to each gallon of renewable fuel produced in or imported into the United States. As a producer of petroleum-based transportation fuels, we are obligated to blend renewable fuels into the products we produce at a rate that is at least commensurate to the EPA’s quota and, to the extent we do not, we must purchase RINs in the open market to satisfy our obligation under the RFS program.

We are exposed to the volatility in the market price of RINs. We cannot predict the future prices of RINs. RINs prices are dependent upon a variety of factors, including EPA regulations, the availability of RINs for purchase, the price at which RINs can be purchased, and levels of transportation fuels produced, all of which can vary significantly from quarter to quarter. If sufficient RINs are unavailable for purchase or if we have to pay a significantly higher price for RINs, or if we are otherwise unable to meet the EPA’s RFS mandates, our results of operations and cash flows could be adversely affected.
