Accounting Policies [Abstract]
BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES	1. BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation General The terms “Valero,” “we,” “our,” and “us,” as used in this report, 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. Operating results for the three months ended March 31, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019 . The balance sheet as of December 31, 2018 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, 2018 . Reclassifications Effective January 1, 2019, we revised our reportable segments to reflect a new reportable segment — renewable diesel. The renewable diesel segment includes the operations of Diamond Green Diesel Holdings LLC (DGD), our consolidated joint venture as discussed in Note 8 , which were transferred from the refining segment. Also effective January 1, 2019, we no longer have a VLP segment, and we now include the operations of Valero Energy Partners LP and its consolidated subsidiaries (VLP) in our refining segment. Our prior period segment information has been retrospectively adjusted to reflect our current segment presentation. See Note 2 regarding our merger with VLP, which occurred on January 10, 2019, and Note 11 for segment information. 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. Leases Background We adopted the provisions of Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 842, “Leases,” (Topic 842) on January 1, 2019, as described below in “Accounting Pronouncements Adopted on January 1, 2019.” Accordingly, our lease accounting policy has been revised to reflect the adoption of this standard. Revised Policy We evaluate if a contract is or contains a lease at inception of the contract. If we determine that a contract is or contains a lease, we recognize a right-of-use (ROU) asset and lease liability at the commencement date of the lease based on the present value of lease payments over the lease term. The present value of the lease payments is determined by using the implicit rate when readily determinable, or if not, our incremental borrowing rate for a term similar to the duration of the lease based on information available at the commencement date. Lease terms include options to extend or terminate the lease when it is reasonably certain that we will exercise those options. We recognize ROU assets and lease liabilities for leasing arrangements with terms greater than one year. Except for the marine transportation asset class, we account for lease and non-lease components in a contract as a single lease component for all classes of underlying assets. Our marine transportation contracts include non-lease components such as maintenance and crew costs. We allocate the consideration in these contracts based on pricing information provided by the third-party broker. Expense for an operating lease is recognized as a single lease cost on a straight-line basis over the lease term and reflected in the appropriate income statement line item based on the leased asset’s function. Amortization expense of a finance lease ROU asset is recognized on a straight-line basis over the lease term and reflected in “depreciation and amortization expense,” and interest expense is incurred based on the carrying value of the lease liability and reflected in “interest and debt expense, net of capitalized interest.” Accounting Pronouncements Adopted on January 1, 2019 Topic 842 As previously noted, we adopted the provisions of Topic 842 on January 1, 2019. Topic 842 increases the transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. Topic 842 supersedes previous lease accounting requirements under FASB ASC Topic 840, “Leases,” (Topic 840). We adopted Topic 842 using the optional transition method that permits us to apply the new disclosure requirements beginning in 2019 and continue to present comparative period information as required under Topic 840; however, we did not have a cumulative-effect adjustment to the opening balance of retained earnings at the date of adoption. In addition, we elected the transition practical expedient package that permits us to not reassess our prior conclusions about lease identification, lease classification, and initial direct costs under the new standard, as well as the practical expedient that permits us to not assess existing land easements under the new standard. See “Leases” above for a discussion of our accounting policy affected by our adoption of Topic 842. Also see Note 4 for information on our leases. In preparation for the adoption of Topic 842, we enhanced our contracting and lease evaluation systems and related processes, and we developed a new lease accounting system to capture our leases and support the required disclosures. We integrated our lease accounting system with our general ledger and modified our related procurement and payment processes. Adoption of this standard resulted in (i) the recognition of ROU assets and lease liabilities for our operating leases of $1.3 billion , (ii) the derecognition of existing assets under construction of $539 million related to a build-to-suit lease arrangement with respect to the MVP Terminal (see Note 6 under “ Commitments— MVP Terminal”), and (iii) the presentation of new disclosures about our leasing activities beginning in the first quarter of 2019. Adoption of this standard did not impact our results of operations or liquidity, and our accounting for finance leases is substantially unchanged. Other In addition to the adoption of Topic 842 discussed above, we adopted the following Accounting Standards Update (ASU) during the three months ended March 31, 2019 . Our adoption of this ASU did not affect our financial statements or related disclosures. ASU Adoption Date Basis of Adoption 2017-12 Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities January 1, 2019 Cumulative effect Accounting Pronouncements Not Yet Adopted The following ASUs have not yet been adopted and are not expected to have a material impact on our financial statements or related disclosures.

MERGER WITH VLP	2. MERGER WITH VLP On January 10, 2019, we completed our acquisition of all of the outstanding publicly held common units of VLP pursuant to a definitive Agreement and Plan of Merger (Merger Agreement, and together with the transactions contemplated thereby, the Merger Transaction) with VLP. Upon completion of the Merger Transaction, each outstanding publicly held common unit was converted into the right to receive $42.25 per common unit in cash without any interest thereon, and all such publicly traded common units were automatically canceled and ceased to exist. Upon completion of the Merger Transaction, we paid aggregate merger consideration of $950 million , which was funded with available cash on hand. Prior to the completion of the Merger Transaction, we consolidated the financial statements of VLP (see Note 8

LEASES	4. LEASES General We have entered into long-term leasing arrangements for the right to use various classes of underlying assets as follows: • Pipelines, Terminals, and Tanks includes facilities and equipment used in the storage, transportation, production, and sale of refinery feedstock, refined petroleum product, and corn inventories; • Marine Transportation includes time charters for ocean-going tankers and coastal vessels; • Rail Transportation includes railcars and related storage facilities; • Feedstock Processing Equipment includes machinery, equipment, and various facilities used in our refining, ethanol, and renewable diesel operations; • Energy and Gases includes facilities and equipment related to industrial gases and power used in our operations; and • Real Estate includes land and rights-of-way associated with our refineries and pipelines, as well as office facilities. In addition to fixed lease payments, some arrangements contain provisions for variable lease payments. Certain leases for pipelines, terminals, and tanks provide for variable lease payments based on, among other things, throughput volumes in excess of a base amount. Certain marine transportation leases contain provisions for payments that are contingent on usage. Additionally, if the rental increases are not scheduled in the lease, such as an increase based on subsequent changes in the index or rate, those rents are considered variable lease payments. In all instances, variable lease payments are recognized in the period in which the obligation for those payments is incurred. Lease Costs and Other Supplemental Information In accordance with Topic 842, our total lease cost comprises costs that are included in our income statement, as well as costs capitalized as part of an item of property, plant, and equipment or inventory.

COMMITMENTS AND CONTINGENCIES	6. COMMITMENTS AND CONTINGENCIES Commitments MVP Terminal We have a 50 percent membership interest in MVP Terminalling, LLC (MVP), a Delaware limited liability company formed in September 2017 with a subsidiary of Magellan Midstream Partners LP (Magellan), to construct, own, and operate the Magellan Valero Pasadena marine terminal (MVP Terminal) located adjacent to the Houston Ship Channel in Pasadena, Texas. Construction of phases one and two of the project began in 2017 with a total estimated cost of approximately $840 million , of which we have committed to contribute 50 percent (approximately $420 million ). The project could expand up to four phases with a total project cost of approximately $1.4 billion if warranted by additional demand and agreed to by Magellan and us. Since inception, we have contributed $303 million to MVP, of which $56 million was contributed during the three months ended March 31, 2019 . Concurrent with the formation of MVP, we entered into a terminaling agreement with MVP to utilize the MVP Terminal upon completion of phase two, which is expected to occur in late 2019 . The terminaling agreement has an initial term of 12 years with two five -year automatic renewals, and year-to-year renewals thereafter. Prior to our adoption of Topic 842 as described in Note 1 , we were considered the accounting owner of the MVP Terminal during the construction period due to our membership interest in MVP and because we determined that the terminaling agreement was a capital lease. Accordingly, as of December 31, 2018, we had recorded an asset of $539 million in property, plant, and equipment representing 100 percent of the construction costs incurred by MVP, as well as capitalized interest incurred by us, and a long-term liability of $292 million payable to Magellan. The amounts recorded for the portion of the construction costs associated with the payable to Magellan were noncash investing and financing items, respectively. On January 1, 2019, as a result of our adoption of Topic 842, we derecognized the asset and liability related to MVP discussed above and recorded our equity investment in MVP of $247 million , which is included in “deferred charges and other assets, net.” The amounts derecognized are noncash investing and financing items, respectively. As of March 31, 2019 , our equity investment in MVP was $303 million . Central Texas Pipeline We have committed to a 40 percent undivided interest in a project with a subsidiary of Magellan to jointly build an estimated 130 -mile, 20 -inch refined petroleum products pipeline with a capacity of up to 150,000 barrels per day from Houston to Hearne, Texas. The pipeline is expected to be completed in the third quarter of 2019. The estimated cost of our 40 percent undivided interest in this pipeline is $170 million . Since inception, expenditures have totaled $81 million , of which $1 million was spent during the three months ended March 31, 2019

Organization, Consolidation and Presentation of Financial Statements [Abstract]
VARIABLE INTEREST ENTITIES	8. VARIABLE INTEREST ENTITIES Consolidated VIEs We consolidate a VIE when we have a variable interest in an entity for which we are the primary beneficiary. As of March 31, 2019 , our significant consolidated VIEs included: • DGD, a joint venture with a subsidiary of Darling Ingredients Inc., which owns and operates a biodiesel plant that processes animal fats, used cooking oils, and other vegetable oils into renewable green diesel; and • Central Mexico Terminals, which is a collective group of three subsidiaries of Infraestructura Energetica Nova, S.A.B. de C.V. (IEnova), a Mexican company and subsidiary of Sempra Energy, a U.S. public company. We have terminaling agreements with Central Mexico Terminals that represent variable interests. We do not have an ownership interest in Central Mexico Terminals. 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 some of our 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).

VLP was formed by us to own, operate, develop, and acquire crude oil and refined petroleum products pipelines, terminals, and other transportation and logistics assets. As of December 31, 2018, we owned a 66.2 percent limited partner interest and a 2.0 percent general partner interest in VLP, and public unitholders owned a 31.8 percent limited partner interest. Upon completion of the Merger Transaction, VLP became our indirect wholly owned subsidiary and, as a result, was no longer a VIE. Non-Consolidated VIEs We hold variable interests in VIEs that have not been consolidated because we are not considered the primary beneficiary. These non-consolidated VIEs are not material to our financial position or results of operations and are primarily accounted for as equity investments. One of our non-consolidated VIEs is MVP, which is described in Note 6 . As of March 31, 2019 , our maximum exposure to loss was $303 million

Segment Reporting [Abstract]
REVENUES AND SEGMENT INFORMATION	11. REVENUES AND SEGMENT INFORMATION Revenue from Contracts with Customers Disaggregation of Revenue Revenue is presented in the table below under “Segment Information” disaggregated by product because this is the level of disaggregation that management has determined to be beneficial to users of our financial statements. Receivables from Contracts with Customers Our receivables from contracts with customers are included in “receivables, net” and totaled $5.3 billion and $4.7 billion as of March 31, 2019 and December 31, 2018 , respectively. Remaining Performance Obligations We have spot and term contracts with customers, the majority of which are spot contracts with no remaining performance obligations. We do not disclose remaining performance obligations for contracts that have terms of one year or less. The transaction price for our remaining term contracts includes a fixed component and variable consideration (i.e., a commodity price), both of which are allocated entirely to a wholly unsatisfied promise to transfer a distinct good that forms part of a single performance obligation. The fixed component is not material and the variable consideration is highly uncertain. Therefore, as of March 31, 2019 , we have not disclosed the aggregate amount of the transaction price allocated to our remaining performance obligations. Segment Information Effective January 1, 2019, 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 — renewable diesel — because of the growing importance of renewable fuels in the market and the growth of our investments in renewable fuels production. The renewable diesel segment includes the operations of DGD, which were transferred from the refining segment on January 1, 2019. Also effective January 1, 2019, we no longer have a VLP segment, and we include the operations of VLP in our refining segment. This change was made because of the Merger Transaction with VLP, as described in Note 2 , and the resulting change in how we manage VLP’s operations. We no longer manage VLP as a business but as logistics assets that support the operations of our refining segment. Our prior period segment information has been retrospectively adjusted to reflect our current segment presentation. We have three reportable segments – refining, ethanol, and renewable diesel. Each segment is a strategic business unit that offers different products and services by employing unique technologies and marketing strategies and whose operations and operating performance are managed and evaluated separately. Operating performance is measured based on the operating income generated by the segment, which includes revenues and expenses that are directly attributable to the management of the respective segment. Intersegment sales are generally derived from transactions made at prevailing market rates. The following is a description of each segment’s business operations. • The refining segment includes the operations of our 15 petroleum refineries, the associated marketing activities, and logistics assets that support our refining operations. The principal products manufactured by our refineries and sold by this segment include gasolines and blendstocks, distillates, and other products. • The ethanol segment includes the operations of our 14 ethanol plants, the associated marketing activities, and logistics assets that support our ethanol operations. The principal products manufactured by our ethanol plants are ethanol and distillers grains. This segment sells some ethanol to the refining segment for blending into gasoline, which is sold to that segment’s customers as a finished gasoline product. • The renewable diesel segment includes the operations of DGD, our consolidated joint venture as discussed in Note 8 . The principal product manufactured by DGD and sold by this segment is renewable diesel. This segment sells some renewable diesel to the refining segment, which is then sold to that segment’s customers. Operations that are not included in any of the reportable segments are included in the corporate category. The following tables reflect information about our operating income by reportable segment (in millions): Refining Ethanol Renewable Diesel Corporate and Eliminations Total Three months ended March 31, 2019: Revenues: Revenues from external customers $ 23,218 $ 793 $ 252 $ — $ 24,263 Intersegment revenues 2 52 51 (105 ) — Total revenues 23,220 845 303 (105 ) 24,263 Cost of sales: Cost of materials and other 21,165 694 224 (105 ) 21,978 Operating expenses (excluding depreciation and amortization expense reflected below) 1,071 125 19 — 1,215 Depreciation and amortization expense 503 23 11 — 537 Total cost of sales 22,739 842 254 (105 ) 23,730 Other operating expenses 2 — — — 2 General and administrative expenses (excluding depreciation and amortization expense reflected below) — — — 209 209 Depreciation and amortization expense — — — 14 14 Operating income by segment $ 479 $ 3 $ 49 $ (223 ) $ 308 Refining Ethanol Renewable Diesel Corporate and Eliminations Total Three months ended March 31, 2018: Revenues: Revenues from external customers $ 25,453 $ 877 $ 108 $ 1 $ 26,439 Intersegment revenues 4 46 42 (92 ) — Total revenues 25,457 923 150 (91 ) 26,439 Cost of sales: Cost of materials and other 23,164 749 (65 ) (92 ) 23,756 Operating expenses (excluding depreciation and amortization expense reflected below) 1,011 111 14 — 1,136 Depreciation and amortization expense 461 18 6 — 485 Total cost of sales 24,636 878 (45 ) (92 ) 25,377 Other operating expenses 10 — — — 10 General and administrative expenses (excluding depreciation and amortization expense reflected below) — — — 238 238 Depreciation and amortization expense — — — 13 13 Operating income by segment $ 811 $ 45 $ 195 $ (250 ) $ 801 The following table provides a disaggregation of revenues from external customers for our principal products by reportable segment (in millions).

These contracts are measured at fair value using the market approach. Exchange-traded futures are valued based on quoted prices from the commodity exchange and are categorized in Level 1 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 plan 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 plan 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 and foreign currency swap agreements related to our international operations to manage our exposure to exchange rate fluctuations on transactions denominated in currencies other than the local (functional) currencies of our 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 similar programs (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. 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 into or out of Level 3 for assets and liabilities held as of March 31, 2019 and December 31, 2018 that were measured at fair value on a recurring basis. There was no significant activity during the three months ended March 31, 2019 and 2018 related to the fair value amounts categorized in Level 3 as of March 31, 2019 and December 31, 2018 . Nonrecurring Fair Value Measurements There were no assets or liabilities that were measured at fair value on a nonrecurring basis as of March 31, 2019 and December 31, 2018 .

PRICE RISK MANAGEMENT ACTIVITIES	14. PRICE RISK MANAGEMENT ACTIVITIES General We are exposed to market risks primarily related to the volatility in the price of commodities, 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 13 ), 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.” 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, such as futures and options. 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. We primarily use commodity derivative instruments as economic hedges, which are not designated as hedging instruments, and we use fair value and cash flow hedges from time to time. We had no commodity derivative instruments outstanding as of March 31, 2019 and 2018 , and no activity during the three months ended March 31, 2019 and 2018 that were designated as fair value or cash flow hedges. Our objectives for holding economic hedges are to (i) manage price volatility in certain feedstock and refined petroleum product inventories and fixed-price purchase contracts, and (ii) lock in the price of forecasted feedstock, refined petroleum product, or natural gas purchases and refined petroleum product sales at existing market prices that we deem favorable. As of March 31, 2019 , 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 corn contracts that are presented in thousands of bushels). Notional Contract Volumes by Year of Maturity Derivative Instrument 2019 2020 Crude oil and refined petroleum products: Futures – long 123,087 3,856 Futures – short 130,923 5,456 Options – long 21,000 — Options – short 21,000 — Corn: Futures – long 19,005 1,275 Futures – short 43,770 3,515 Physical contracts – long 23,726 2,238 Foreign Currency Risk We are exposed to exchange rate fluctuations on transactions related to our international operations that are denominated in currencies other than the local (functional) currencies of our operations. To manage our exposure to these exchange rate fluctuations, we use foreign currency contracts. These contracts are not designated as hedging instruments for accounting purposes and therefore are classified as economic hedges. As of March 31, 2019 , we had foreign currency contracts to purchase $418 million of U.S. dollars, $1.7 billion of U.S. dollar equivalent Canadian dollars, and $300 million of U.S. dollar equivalent pounds sterling. The majority of these commitments matured on or before April 30, 2019 . 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 $91 million and $206 million for the three months ended March 31, 2019 and 2018 , respectively. These amounts are reflected in cost of materials and other. Fair Values of Derivative Instruments The following tables provide information about the fair values of our derivative instruments as of March 31, 2019 and December 31, 2018 (in millions) and the line items in the balance sheets in which the fair values are reflected. See Note 13 for additional information related to the fair values of our derivative instruments. As indicated in Note 13 , 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 following tables, 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.

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.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation General The terms “Valero,” “we,” “our,” and “us,” as used in this report, 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. Operating results for the three months ended March 31, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019 . The balance sheet as of December 31, 2018 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, 2018 .
Reclassifications	Reclassifications Effective January 1, 2019, we revised our reportable segments to reflect a new reportable segment — renewable diesel. The renewable diesel segment includes the operations of Diamond Green Diesel Holdings LLC (DGD), our consolidated joint venture as discussed in Note 8 , which were transferred from the refining segment. Also effective January 1, 2019, we no longer have a VLP segment, and we now include the operations of Valero Energy Partners LP and its consolidated subsidiaries (VLP) in our refining segment. Our prior period segment information has been retrospectively adjusted to reflect our current segment presentation. See Note 2 regarding our merger with VLP, which occurred on January 10, 2019, and Note 11
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S.
Leases	Leases Background We adopted the provisions of Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 842, “Leases,” (Topic 842) on January 1, 2019, as described below in “Accounting Pronouncements Adopted on January 1, 2019.” Accordingly, our lease accounting policy has been revised to reflect the adoption of this standard. Revised Policy We evaluate if a contract is or contains a lease at inception of the contract. If we determine that a contract is or contains a lease, we recognize a right-of-use (ROU) asset and lease liability at the commencement date of the lease based on the present value of lease payments over the lease term. The present value of the lease payments is determined by using the implicit rate when readily determinable, or if not, our incremental borrowing rate for a term similar to the duration of the lease based on information available at the commencement date. Lease terms include options to extend or terminate the lease when it is reasonably certain that we will exercise those options. We recognize ROU assets and lease liabilities for leasing arrangements with terms greater than one year. Except for the marine transportation asset class, we account for lease and non-lease components in a contract as a single lease component for all classes of underlying assets. Our marine transportation contracts include non-lease components such as maintenance and crew costs. We allocate the consideration in these contracts based on pricing information provided by the third-party broker.
New Accounting Pronouncements	Accounting Pronouncements Adopted on January 1, 2019 Topic 842 As previously noted, we adopted the provisions of Topic 842 on January 1, 2019. Topic 842 increases the transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. Topic 842 supersedes previous lease accounting requirements under FASB ASC Topic 840, “Leases,” (Topic 840). We adopted Topic 842 using the optional transition method that permits us to apply the new disclosure requirements beginning in 2019 and continue to present comparative period information as required under Topic 840; however, we did not have a cumulative-effect adjustment to the opening balance of retained earnings at the date of adoption. In addition, we elected the transition practical expedient package that permits us to not reassess our prior conclusions about lease identification, lease classification, and initial direct costs under the new standard, as well as the practical expedient that permits us to not assess existing land easements under the new standard. See “Leases” above for a discussion of our accounting policy affected by our adoption of Topic 842. Also see Note 4 for information on our leases. In preparation for the adoption of Topic 842, we enhanced our contracting and lease evaluation systems and related processes, and we developed a new lease accounting system to capture our leases and support the required disclosures. We integrated our lease accounting system with our general ledger and modified our related procurement and payment processes. Adoption of this standard resulted in (i) the recognition of ROU assets and lease liabilities for our operating leases of $1.3 billion , (ii) the derecognition of existing assets under construction of $539 million related to a build-to-suit lease arrangement with respect to the MVP Terminal (see Note 6 under “ Commitments— MVP Terminal”), and (iii) the presentation of new disclosures about our leasing activities beginning in the first quarter of 2019. Adoption of this standard did not impact our results of operations or liquidity, and our accounting for finance leases is substantially unchanged. Other In addition to the adoption of Topic 842 discussed above, we adopted the following Accounting Standards Update (ASU) during the three months ended March 31, 2019 . Our adoption of this ASU did not affect our financial statements or related disclosures. ASU Adoption Date Basis of Adoption 2017-12 Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities January 1, 2019 Cumulative effect Accounting Pronouncements Not Yet Adopted The following ASUs have not yet been adopted and are not expected to have a material impact on our financial statements or related disclosures.

Variable interest entities	We hold variable interests in VIEs that have not been consolidated because we are not considered the primary beneficiary. These non-consolidated VIEs are not material to our financial position or results of operations and are primarily accounted for as equity investments. One of our non-consolidated VIEs is MVP, which is described in Note 6
Offsetting fair value amounts of commodity derivative contracts	We have elected to offset the fair value amounts recognized for multiple similar derivative contracts executed with the same counterparty, including any related cash collateral assets or obligations as shown below; however, fair value amounts by hierarchy level are presented in the following tables on a gross basis. We have no derivative contracts that are subject to master netting arrangements that are reflected gross on the balance sheet.
Derivatives	We are exposed to market risks primarily related to the volatility in the price of commodities, 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 13 ), 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
Derivative instruments collateral requirements	We do not require any collateral or other security to support derivative instruments into which we enter.
