CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. | BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation
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 information for the three and six months ended June 30, 2014 and 2013 included in these Condensed Notes to Consolidated Financial Statements is derived from our unaudited financial statements. Operating results for the three and six months ended June 30, 2014 are not necessarily indicative of the results that may be expected for the year ending December 31, 2014.
The balance sheet as of December 31, 2013 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, 2013.
Reclassification
As discussed in Note 3, in May 2014, we abandoned the Aruba Refinery. As a result, the refinery’s results of operations have been presented as discontinued operations in the consolidated statements of income for all periods presented.
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.
Income Taxes
In July 2013, the provisions of Accounting Standards Codification (ASC) Topic 740, “Income Taxes,” were amended to provide specific guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists at the reporting date. The amendment requires entities to present an unrecognized tax benefit as a reduction to the deferred tax asset generated by the net operating loss carryforward, similar tax loss, or tax credit carryforward, if such items are available to be used to offset the unrecognized tax benefit. These provisions are effective for interim and annual reporting periods beginning after December 15, 2013 and should be applied prospectively to all unrecognized tax benefits that exist at the effective date, with retrospective application permitted. The adoption of this guidance effective January 1, 2014 did not affect our financial position or results of operations, nor did it require any additional disclosures.

CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
New Accounting Pronouncements
In April 2014, the provisions of ASC Topic 205, “Presentation of Financial Statements,” and ASC Topic 360, “Property, Plant, and Equipment,” were amended to change the criteria for reporting discontinued operations. The provisions of these amendments modify the definition of discontinued operations by limiting discontinued operations reporting to disposals of components of an entity that represent strategic shifts that have or will have a major effect on an entity’s operations and financial results. These amendments require additional disclosures about discontinued operations and new disclosures for other disposals of individually material components of an organization that do not meet the definition of a discontinued operation. In addition, the guidance allows companies to have significant continuing involvement and continuing cash flows with the discontinued operation. These provisions are effective prospectively for annual reporting periods beginning on or after December 15, 2014, and interim periods within those annual periods, with early adoption permitted. The adoption of this guidance effective January 1, 2015 will not affect our financial position or results of operations; however, it may result in changes to the manner in which future dispositions of operations or assets, if any, are presented in our financial statements, or it may require additional disclosures.
In May 2014, the Financial Accounting Standards Board amended the ASC and issued a new accounting standard, Topic 606, “Revenue from Contracts with Customers,” to clarify the principles for recognizing revenue. The core principle of the new standard is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The standard also requires improved interim and annual disclosures that enable the users of financial statements to better understand the nature, amount, timing, and uncertainty of revenues and cash flows arising from contracts with customers. The new standard is effective for annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period, and can be adopted either retrospectively to each prior reporting period presented using a practical expedient as allowed by the new standard or retrospectively with a cumulative effect adjustment to retained earnings as of the date of initial application. Early adoption is not permitted. We are currently evaluating the effect that adopting this new standard will have on our consolidated financial statements and related disclosures.

2. | VALERO ENERGY PARTNERS LP

In July 2013, we formed Valero Energy Partners LP (VLP), a master limited partnership, to own, operate, develop, and acquire crude oil and refined petroleum products pipelines, terminals, and other transportation and logistics assets. On December 16, 2013, VLP completed its initial public offering (the Offering) of 17,250,000 common units at a price of $23.00 per unit. VLP received $369 million in net proceeds from the sale of the units, after deducting underwriting fees, structuring fees, and other offering costs. As of June 30, 2014, VLP’s assets included crude oil and refined petroleum products pipeline and terminal systems in the U.S. Gulf Coast and U.S. Mid-Continent regions that are integral to the operations of our Port Arthur, McKee, and Memphis Refineries.
As of June 30, 2014 and December 31, 2013, we owned a 68.6 percent limited partner interest and a 2 percent general partner interest in VLP, and the public owned a 29.4 percent limited partner interest. VLP’s cash and temporary cash investments were $382 million and $375 million as of June 30, 2014 and December 31, 2013, respectively. Valero consolidates the financial statements of VLP into its financial statements and as such, VLP’s cash and temporary cash investments are included in Valero’s consolidated cash and temporary
6

CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
cash investments. However, VLP’s cash and temporary cash investments can be used only to settle its obligations. In addition, VLP’s partnership capital attributable to the public’s ownership interest in VLP of $372 million and $370 million as of June 30, 2014 and December 31, 2013, respectively, is reflected in noncontrolling interests.
We have agreements with VLP that establish fees for certain general and administrative services, and operational and maintenance services provided by us. In addition, we have a master transportation services agreement and a master terminal services agreement with VLP under which VLP provides commercial transportation and terminaling services to us. These transactions are eliminated in consolidation.
On July 1, 2014, we sold our Texas Crude Systems Business to VLP for total cash consideration of $154 million. The Texas Crude Systems Business is engaged in the business of transporting, terminaling, and storing crude oil and refined petroleum products through various pipeline and terminal systems that compose the McKee Crude System, the Three Rivers Crude System, and the Wynnewood Products System. In connection with this transaction, we entered into additional schedules under our existing master transportation services agreement and master terminal services agreement with VLP with respect to each system. Each system’s schedule constitutes a binding agreement between us and VLP for transportation or terminaling services (as applicable). Each schedule has an initial term of 10 years with one five-year renewal term at our option and contains minimum throughput requirements and inflation escalators. We also amended and restated our omnibus agreement with VLP and amended our services and secondment agreement with the general partner of VLP. Because Valero consolidates the financial statements of VLP into its financial statements, this transaction will be eliminated in consolidation and will not impact Valero’s consolidated financial position or cash flows. As such, Valero’s consolidated cash and temporary cash investments will not change because of this transaction, however VLP’s cash and temporary cash investments will decrease by $154 million.

3. | DISCONTINUED OPERATIONS

In May 2014, we decided to abandon our Aruba Refinery, except for the associated crude oil and refined products terminal assets that we continue to operate. As a result of our decision, the refinery’s results of operations have been presented in this report as discontinued operations for the three and six months ended June 30, 2014 and 2013.
We had suspended operations of the refinery in 2012 and at that time we wrote off the entire carrying value of the refinery’s idled crude oil processing units and related infrastructure (refining assets) and supplies inventories that supported the refining operations. In addition, we terminated the employees who supported the refining operations and incurred severance costs at that time. Even though we suspended refining operations in 2012, we continued to maintain the refining assets to allow them to be restarted and did not abandon them until our recent decision to no longer pursue options to restart refining operations.
The Aruba Refinery resides on land leased from the Government of Aruba (GOA) and our agreements with the GOA require us to dismantle our leasehold improvements under certain conditions. Because of our May 2014 decision to abandon the refining assets, we believe the GOA will require us to dismantle those assets. As a result, we recognized an asset retirement obligation of $59 million, which was charged to expense during the three months ended June 30, 2014, and is reflected in discontinued operations. We had not recognized an asset retirement obligation previously due to our belief that we would not be required to

Table of Contents
VALERO ENERGY CORPORATION
CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
dismantle the assets as long as we intended to operate them. In the second quarter of 2014, we also recognized liabilities of $4 million relating to obligations under certain contracts, including a liability for the remaining lease payments for the land on which the refining assets reside.
Of the $63 million of liabilities recorded in connection with our decision to abandon the Aruba Refinery, $30 million is classified as a current liability and is reflected in accrued expenses, and $33 million is classified as a long-term liability and is reflected in other long-term liabilities as of June 30, 2014. Our agreements with the GOA require us to complete the dismantlement activities within 3 years.
Selected results of operations of the Aruba Refinery are shown below (in millions).

There was no tax benefit recognized for the loss from discontinued operations for the the three and six months ended June 30, 2014 as we do not expect to realize this tax benefit.

4. | SEPARATION OF RETAIL BUSINESS

On May 1, 2013, we completed the separation of our retail business by creating an independent public company named CST Brands, Inc. (CST) and distributing 80 percent of the outstanding shares of CST common stock to our stockholders. Each Valero stockholder received one share of CST common stock for every nine shares of Valero common stock held at the close of business on the record date of April 19, 2013.
In connection with the separation, we received an aggregate of $1.05 billion in cash, consisting of $550 million from the issuance of short-term debt to a third-party financial institution on April 16, 2013 and $500 million distributed to us by CST on May 1, 2013. The cash distributed to us by CST was borrowed by CST on May 1, 2013 under its senior secured credit facility. Also on May 1, 2013, CST issued $550 million of its senior unsecured bonds to us, and we exchanged those bonds with the third-party financial institution in satisfaction of our short-term debt. Immediately prior to May 1, 2013, subsidiaries of CST held $315 million of cash, and CST retained that cash following the distribution on May 1, 2013. We also incurred $30 million in costs during the three months ended June 30, 2013 to effect the separation, which were included in general and administrative expenses.
We also entered into long-term motor fuel supply agreements with CST in the U.S. and Canada. The nature and significance of our agreements to supply motor fuel to CST through 2028 represents a continuation of activities with CST for accounting purposes. As such, the historical results of operations of our retail business have not been reported as discontinued operations in our statements of income.
In November 2013, we disposed of our 20 percent retained interest in CST.

Selected historical results of operations of our retail business prior to the separation are disclosed in Note 11. Subsequent to May 1, 2013 and through June 30, 2013, our share of CST’s results of operations was reflected in “other income, net.” Our share of income taxes incurred directly by CST during this period was reported in the equity in earnings from CST, and as such is not included in income taxes in our statements of income.

5. | INVENTORIES

Inventories consisted of the following (in millions):

| June 30, 2014 |  | December 31, 2013
Refinery feedstocks | $ | 3,380 |  |  | $ | 2,135 |
Refined products and blendstocks | 2,732 |  |  | 3,231 |
Ethanol feedstocks and products | 182 |  |  | 166 |
Materials and supplies | 232 |  |  | 226 |
Inventories | $ | 6,526 |  |  | $ | 5,758 |

As of June 30, 2014 and December 31, 2013, the replacement cost (market value) of last in, first out (LIFO) inventories exceeded their LIFO carrying amounts by approximately $7.2 billion and $6.9 billion, respectively. As of June 30, 2014 and December 31, 2013, our non-LIFO inventories accounted for $914 million and $851 million, respectively, of our total inventories.

6. | DEBT

Credit Facilities
Revolver
We have a $3 billion revolving credit facility (the Revolver) that has a maturity date of November 2018. We have the option to increase the aggregate commitments under the Revolver to $4.5 billion, subject to, among other things, the consent of the existing lenders whose commitments will be increased or any additional lenders providing such additional capacity. The Revolver has certain restrictive covenants, including a maximum debt-to-capitalization ratio of 60 percent. As of June 30, 2014 and December 31, 2013, our debt-to-capitalization ratios, calculated in accordance with the terms of the Revolver, were 14 percent and 12 percent, respectively. We believe that we will remain in compliance with this covenant.
VLP Revolver
VLP has a $300 million senior unsecured revolving credit facility agreement (the VLP Revolver) that has a maturity date of December 2018. The VLP Revolver is available only to the operations of VLP, and creditors of VLP do not have recourse against Valero.
Canadian Facility
In addition to the Revolver and the VLP Revolver, one of our Canadian subsidiaries has a C$50 million committed revolving credit facility under which it may borrow and obtain letters of credit that has a maturity date of November 2014.

Activities Under Our Credit Facilities
During the six months ended June 30, 2014 and 2013, we had no borrowings or repayments under the Revolver, the VLP Revolver, or our Canadian revolving credit facility. As of June 30, 2014 and December 31, 2013, we had no borrowings outstanding under these credit facilities.
We had outstanding letters of credit under our committed lines of credit as follows (in millions):

|  |  |  |  | Amounts Outstanding
| Borrowing Capacity |  | Expiration |  | June 30, 2014 |  | December 31, 2013
Letter of credit facilities | $ | 550 |  |  | June 2015 |  | $ | — |  |  | $ | 278 |
Revolver | $ | 3,000 |  |  | November 2018 |  | $ | 59 |  |  | $ | 59 |
VLP Revolver | $ | 300 |  |  | December 2018 |  | $ | — |  |  | $ | — |
Canadian revolving credit facility | C$ | 50 |  |  | November 2014 |  | C$ | 10 |  |  | C$ | 10 |

As of June 30, 2014 and December 31, 2013, we had $206 million and $189 million, respectively, of letters of credit outstanding under our uncommitted short-term bank credit facilities.
Non-Bank Debt
During the six months ended June 30, 2014, we made a scheduled debt repayment of $200 million related to our 4.75% senior notes. During the six months ended June 30, 2013, we made scheduled debt repayments of $300 million related to our 4.75% senior notes and $180 million related to our 6.7% senior notes.
Accounts Receivable Sales Facility
We have an accounts receivable sales facility with a group of third-party entities and financial institutions to sell up to $1.5 billion of eligible trade receivables on a revolving basis. In July 2014, we amended this facility to extend the maturity date to July 2015. 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 six months ended June 30, 2014 and 2013, we had no proceeds from or repayments under our accounts receivable sales facility. As of June 30, 2014 and December 31, 2013, we had $100 million outstanding under our accounts receivable sales facility.
Capitalized Interest
Capitalized interest was $18 million and $45 million for the three months ended June 30, 2014 and 2013, respectively, and $35 million and $85 million for the six months ended June 30, 2014 and 2013, respectively.

7. | COMMITMENTS AND CONTINGENCIES

Environmental Matter
We are involved, together with several other companies, in an environmental cleanup in the Village of Hartford, Illinois (the Village) and the adjacent shutdown refinery site, which we acquired as part of a prior acquisition. In cooperation with some of the other companies, we have been conducting initial mitigation and cleanup response pursuant to an administrative order issued by the U.S. Environmental Protection Agency (EPA). The U.S. EPA is seeking further cleanup obligations from us and other potentially responsible parties for the Village. In parallel with the Village cleanup, we are also in litigation with the State of Illinois EPA and other potentially responsible parties relating to the remediation of the shutdown refinery site. In each of these matters, we have various defenses and rights for contribution from the other responsible parties. We have accrued for our own expected contribution obligations. However, because of the unpredictable nature of these cleanups and the methodology for allocation of liabilities, 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.

In February 2013, we announced changes to certain of our U.S. qualified pension plans that cover the majority of our U.S. employees who work in our refining segment and corporate operations. Benefits under our primary pension plan changed from a final average pay formula to a cash balance formula with staged effective dates that commence either on July 1, 2013 or January 1, 2015 depending on the age and service of the affected employees. All final average pay benefits will be frozen as of December 31, 2014, with all future benefits to be earned under the new cash balance formula. These plan amendments resulted in a $328 million decrease to pension liabilities and a related increase to other comprehensive income during the six months ended June 30, 2013. The benefit of this remeasurement will be amortized into income through 2025.
Our anticipated contributions to our pension and other postretirement benefit plans during 2014 have not changed from amounts previously disclosed in our financial statements for the year ended December 31, 2013. We contributed $22 million and $22 million, respectively, to our pension plans and $9 million and $8 million, respectively, to our other postretirement benefit plans during the six months ended June 30, 2014 and 2013.

The following table reflects potentially dilutive securities (in millions) that were excluded from the calculation of “earnings per common share from continuing operations – assuming dilution” as the effect of including such securities would have been antidilutive. Stock options were excluded from weighted-average common shares outstanding – assuming dilution because the exercise price of the stock option was greater than the average market price of our common shares during each reporting period.

11. | SEGMENT INFORMATION

In May 2013, we completed the separation of our retail business, CST, and as a result, we no longer operate a retail business or report retail segment operating results. Segment activity related to our retail business prior to the separation is reflected in the retail segment results below. Motor fuel sales to CST, which were eliminated in consolidation prior to the separation, are reported as refining segment operating revenues from external customers after May 1, 2013.
The following table reflects activity related to our reportable segments (in millions):

In March 2014, we purchased an idled corn ethanol plant in Mount Vernon, Indiana for $34 million from a wholly owned subsidiary of Aventine Renewable Energy Holdings, Inc. We expect to resume production during the third quarter of 2014. We will finalize our purchase accounting once a determination of the fair values of the assets acquired and liabilities assumed is available, pending the completion of independent appraisals and other evaluations.

12. | SUPPLEMENTAL CASH FLOW INFORMATION

In order to determine net cash provided by operating activities, net income is adjusted by, among other things, changes in current assets and current liabilities as follows (in millions):

| Six Months Ended June 30,
| 2014 |  | 2013
Decrease (increase) in current assets: |  |  |
Receivables, net | $ | 837 |  |  | $ | 412 |
Inventories | (721 | ) |  | (824 | )
Income taxes receivable | (16 | ) |  | 31 |
Prepaid expenses and other | 11 |  |  | 2 |
Increase (decrease) in current liabilities: |  |  |
Accounts payable | (707 | ) |  | 625 |
Accrued expenses | 12 |  |  | (44 | )
Taxes other than income taxes | (71 | ) |  | 268 |
Income taxes payable | (369 | ) |  | (26 | )
Changes in current assets and current liabilities | $ | (1,024 | ) |  | $ | 444 |

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, as well as the effect of certain noncash investing and financing activities discussed below;

• | the amounts shown above for the six months ended June 30, 2013 exclude the change in current assets and current liabilities resulting from the separation of our retail business as described in Note 4;

CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

• | 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.

There were no significant noncash investing activities for the six months ended June 30, 2014 and 2013. Noncash financing activities for the six months ended June 30, 2014 included an accrual of $104 million for the purchase of 2,000,000 shares of our common stock, which was settled in early July 2014. Noncash financing activities for the six months ended June 30, 2013 included the exchange of CST’s senior unsecured bonds with the third-party financial institution in satisfaction of our short-term debt as described in Note 4.
Cash flows related to interest and income taxes were as follows (in millions):

| Six Months Ended June 30,
| 2014 |  | 2013
Interest paid in excess of amount capitalized | $ | 197 |  |  | $ | 160 |
Income taxes paid, net | 1,054 |  |  | 243 |

Cash flows related to the discontinued operations of the Aruba Refinery were immaterial for the six months ended June 30, 2014 and 2013.

13. | 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.

Recurring Fair Value Measurements
The tables below present information (in millions) about our assets and liabilities recognized at their fair values in our balance sheets categorized according to the fair value hierarchy of the inputs utilized by us to determine the fair values as of June 30, 2014 and December 31, 2013.
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 on a gross basis in the tables below. We have no derivative contracts that are subject to master netting arrangements that are reflected gross on the balance sheet.

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 14, 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 firm commitments to purchase crude oil feedstocks and the fair value of fixed-price corn purchase contracts, and as disclosed in Note 14, some of these contracts are designated as hedging instruments. The fair values of these firm commitments and 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 by our international operations to manage our exposure to exchange rate fluctuations on transactions

25

CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
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.

• | Our biofuels blending obligation represents a liability for the purchase of biofuel credits (primarily Renewable Identification Numbers (RINs) in the U.S.) needed to satisfy our obligation to blend biofuels into the products we produce. To the degree we are unable to blend at percentages required under various governmental and regulatory programs, we must purchase biofuel credits to comply with these programs. These programs are further described in Note 14 under “Compliance Program Price Risk.” This liability is based on our deficit in biofuel credits as of the balance sheet date, if any, after considering any biofuel credits acquired or under contract, and is equal to the product of the biofuel credits deficit and the market price of these credits as of the balance sheet date. This liability is categorized in Level 2 of the fair value hierarchy and is measured at fair value using the market approach based on quoted prices from an independent pricing service.

There were no transfers between Level 1 and Level 2 for assets and liabilities held as of June 30, 2014 and December 31, 2013 that were measured at fair value on a recurring basis.
There was no activity during the three and six months ended June 30, 2014 and 2013 related to the fair value amounts categorized in Level 3 as of June 30, 2014 and December 31, 2013.
Nonrecurring Fair Value Measurements
There were no assets or liabilities that were measured at fair value on a nonrecurring basis as of June 30, 2014 and December 31, 2013.
Other Financial Instruments
Financial instruments that we recognize in our balance sheets at their carrying amounts are shown in the table below (in millions):

| June 30, 2014 |  | December 31, 2013
| Carrying Amount |  | Fair Value |  | Carrying Amount |  | Fair Value
Financial assets: |  |  |  |  |  |  |
Cash and temporary cash investments | $ | 3,480 |  |  | $ | 3,480 |  |  | $ | 4,292 |  |  | $ | 4,292 |
Financial liabilities: |  |  |  |  |  |  |
Debt (excluding capital leases) | 6,348 |  |  | 7,862 |  |  | 6,525 |  |  | 7,659 |

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).

14. | PRICE RISK MANAGEMENT ACTIVITIES

We are exposed to market risks related to the volatility in the price of commodities, interest rates, and foreign currency exchange rates. We enter into derivative instruments to manage some of these risks, including derivative instruments related to the various commodities we purchase or produce, interest rate swaps, 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.” In addition, the effect of these derivative instruments on our income is summarized below under “Effect of Derivative Instruments on Income and Other Comprehensive Income.”
When we enter into a derivative instrument, it is designated as a fair value hedge, a cash flow hedge, an economic hedge, or a trading derivative. The gain or loss on a derivative instrument designated and qualifying as a fair value hedge, as well as the offsetting loss or gain on the hedged item attributable to the hedged risk, is recognized currently in income in the same period. The effective portion of the gain or loss on a derivative instrument designated and qualifying as a cash flow hedge is initially reported as a component of other comprehensive income and is then recorded into income in the period or periods during which the hedged forecasted transaction affects income. The ineffective portion of the gain or loss on the cash flow derivative instrument, if any, is recognized in income as incurred. For our economic hedges (derivative instruments not designated as fair value or cash flow hedges) and for derivative instruments entered into by us for trading purposes, the derivative instrument is recorded at fair value and changes in the fair value of the derivative instrument are recognized currently in 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.
We are also exposed to market risk related to the volatility in the price of credits needed to comply with various governmental and regulatory 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.
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 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 a risk control group to ensure compliance with our stated risk management policy that has been approved by our board of directors.
For risk management purposes, we use fair value hedges, cash flow hedges, and economic hedges. In addition to the use of derivative instruments to manage commodity price risk, we also enter into certain commodity derivative instruments for trading purposes. Our objective for entering into each type of hedge or trading derivative is described below.

CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

• | Fair Value Hedges – Fair value hedges are used to hedge price volatility in certain refining inventories and firm commitments to purchase inventories. The level of activity for our fair value hedges is based on the level of our operating inventories, and generally represents the amount by which our inventories differ from our previous year-end LIFO inventory levels.

As of June 30, 2014, we had no outstanding commodity derivative instruments that were entered into to hedge crude oil and refined product inventories and no commodity derivative instruments related to the physical purchase of crude oil and refined products at a fixed price.

• | Cash Flow Hedges – Cash flow hedges are used to hedge price volatility in certain forecasted feedstock and refined product purchases, refined product sales, and natural gas purchases. The objective of our cash flow hedges is to lock in the price of forecasted feedstock, refined product, or natural gas purchases or refined product sales at existing market prices that we deem favorable.

As of June 30, 2014, we had the following outstanding commodity derivative instruments that were entered into to hedge forecasted purchases of crude oil and sales of refined products. The information presents the notional volume of outstanding contracts by type of instrument and year of maturity (volumes in thousands of barrels).

• | Economic Hedges – Economic hedges represent commodity derivative instruments that are not designated as fair value or cash flow hedges and are used to manage price volatility in certain (i) refinery feedstock, refined product, animal fat feedstock, and corn inventories, (ii) forecasted refinery feedstock, refined product, and corn purchases, and refined product sales, and (iii) fixed-price corn purchase contracts. Our objective for entering into economic hedges is consistent with the objectives discussed above for fair value hedges and cash flow hedges. However, the economic hedges are not designated as a fair value hedge or a cash flow hedge for accounting purposes, usually due to the difficulty of establishing the required documentation at the date that the derivative instrument is entered into that would allow us to achieve “hedge deferral accounting.”

As of June 30, 2014, 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).

• | Trading Derivatives – Our objective for entering into commodity derivative instruments for trading purposes is to take advantage of existing market conditions related to future results of operations and cash flows.

As of June 30, 2014, we had the following outstanding commodity derivative instruments that were entered into for trading purposes.

Interest Rate Risk
Our primary market risk exposure for changes in interest rates relates to our debt obligations. We manage our exposure to changing interest rates through the use of a combination of fixed-rate and floating-rate debt. In addition, at times we have used interest rate swap agreements to manage our fixed to floating interest rate position by converting certain fixed-rate debt to floating-rate debt. We had no interest rate derivative instruments outstanding as of June 30, 2014 or December 31, 2013, or during the three and six months ended June 30, 2014 and 2013.
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 they are classified as economic hedges. As of June 30, 2014, we had commitments to purchase $692 million of U.S. dollars. The majority of these commitments matured on or before July 31, 2014, resulting in an immaterial gain in the third quarter of 2014.

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 programs. The most significant programs impacting our operations are those that 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 $137 million for the three months ended June 30, 2014 and 2013, respectively, and $183 million and $267 million for the six months ended June 30, 2014 and 2013, respectively. These amounts are reflected in cost of sales.
Fair Values of Derivative Instruments
The following tables provide information about the fair values of our derivative instruments as of June 30, 2014 and December 31, 2013 (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 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 a risk control group to ensure compliance with our stated risk management policy. Concentrations of customers in the refining industry may impact our overall exposure to counterparty risk because these customers may be similarly affected by changes in economic or other conditions. In addition, financial services companies are the counterparties in certain of our price risk management activities, and such financial services companies may be adversely affected by periods of uncertainty and illiquidity in the credit and capital markets.
There were no material amounts due from counterparties in the refining or financial services industry as of June 30, 2014 or December 31, 2013. 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.

• | rulings, judgments, or settlements in litigation or other legal or regulatory matters, including unexpected environmental remediation costs, in excess of any reserves or insurance coverage;

• | legislative or regulatory action, including the introduction or enactment of legislation or rulemakings by governmental authorities, including tax and environmental regulations, such as those to be implemented under the California Global Warming Solutions Act (also known as AB 32) and the United States (U.S.) Environmental Protection Agency’s (EPA) regulation of greenhouse gases, which may adversely affect our business or operations;

• | changes in the credit ratings assigned to our debt securities and trade credit;

• | changes in currency exchange rates, including the value of the Canadian dollar, the pound sterling, and the euro relative to the U.S. dollar; and

• | overall economic conditions, including the stability and liquidity of financial markets.

Any one of these factors, or a combination of these factors, could materially affect our future results of operations and whether any forward-looking statements ultimately prove to be accurate. Our forward-looking statements are not guarantees of future performance, and actual results and future performance may differ materially from those suggested in any forward-looking statements. We do not intend to update these statements unless we are required by the securities laws to do so.
All subsequent written and oral forward-looking statements attributable to us or persons acting on our behalf are expressly qualified in their entirety by the foregoing. We undertake no obligation to publicly release any revisions to any such forward-looking statements that may be made to reflect events or circumstances after the date of this report or to reflect the occurrence of unanticipated events.

OVERVIEW AND OUTLOOK
Overview
For the second quarter of 2014, we reported net income attributable to Valero stockholders from continuing operations of $651 million, or $1.22 per share (assuming dilution), compared to $463 million, or $0.84 per share (assuming dilution), for the second quarter of 2013. The increase of $188 million was due primarily to the increase of $280 million in our operating income as outlined by business segment in the table below (in millions).

|  | Three Months Ended June 30,
|  | 2014 |  | 2013 |  | Change
Operating income (loss) by business segment: |  |  |  |  |  |
Refining |  | $ | 1,079 |  |  | $ | 918 |  |  | $ | 161 |
Ethanol |  | 187 |  |  | 95 |  |  | 92 |
Retail |  | — |  |  | 39 |  |  | (39 | )
Corporate |  | (181 | ) |  | (247 | ) |  | 66 |
Total |  | $ | 1,085 |  |  | $ | 805 |  |  | $ | 280 |

The $161 million increase in refining segment operating income in the second quarter of 2014 compared to the second quarter of 2013 was due primarily to higher refining throughput margin per barrel and higher throughput volumes in most of our regions, partially offset by higher energy costs and higher depreciation expense between the periods. Our ethanol segment operating income increased $92 million in the second quarter of 2014 compared to the second quarter of 2013 due to higher gross margin per gallon.
On May 1, 2013, we completed the separation of our retail business, creating an independent public company named CST Brands, Inc. (CST), and as a result, we no longer operate a retail business. Therefore, we did not have any retail segment operating results for the second quarter of 2014, resulting in the $39 million decrease in retail segment operating income in the second quarter of 2014 compared to the second quarter of 2013.
For the first six months of 2014, we reported net income attributable to Valero stockholders from continuing operations of $1.5 billion, or $2.77 per share (assuming dilution), compared to $1.1 billion, or $2.02 per share (assuming dilution), for the first six months of 2013. The increase of $366 million was due primarily to the increase of $573 million in our operating income as outlined by business segment in the table below (in millions).

|  | Six Months Ended June 30,
|  | 2014 |  | 2013 |  | Change
Operating income (loss) by business segment: |  |  |  |  |  |
Refining |  | $ | 2,359 |  |  | $ | 2,127 |  |  | $ | 232 |
Ethanol |  | 430 |  |  | 109 |  |  | 321 |
Retail |  | — |  |  | 81 |  |  | (81 | )
Corporate |  | (353 | ) |  | (454 | ) |  | 101 |
Total |  | $ | 2,436 |  |  | $ | 1,863 |  |  | $ | 573 |

The $232 million increase in refining segment operating income in the first six months of 2014 compared to the first six months of 2013 was due primarily to higher refining throughput margin per barrel and higher throughput volumes in most of our regions, partially offset by higher energy costs and higher depreciation expense between the periods. Our ethanol segment operating income increased $321 million in the first six

months of 2014 compared to the first six months of 2013 due to higher gross margin per gallon, partially offset by higher energy costs.
As previously discussed, we no longer operate a retail business. Therefore, we did not have any retail segment operating results for the first six months of 2014, which resulted in the $81 million decrease in retail segment operating income in the first six months of 2014 compared to the first six months of 2013.
In May 2014, we decided to abandon our Aruba Refinery, except for the associated crude oil and refined products terminal assets that we continue to operate, as further described in Note 3 of Condensed Notes to Consolidated Financial Statements. As a result, the Aruba Refinery’s results of operations have been presented as discontinued operations for all periods presented under “RESULTS OF OPERATIONS.”
Additional analysis of the changes in the operating income of our business segments and other components of net income attributable to Valero stockholders is provided below under “RESULTS OF OPERATIONS.”
Outlook
Our refining segment benefits from processing sour crude oils (such as Mars and Maya crude oil) and light sweet crude oils (such as West Texas Intermediate and Louisiana Light Sweet crude oil) due to the favorable discounts between the prices of these types of crude oil and the price of Brent crude oil. Because the market for refined products generally tracks the price of Brent crude oil, which is a benchmark sweet crude oil, we benefit when we process crude oils that are priced at a discount to Brent crude oil. The discounts in the prices of certain light sweet crude oils and sour crude oils compared to the price of Brent crude oil in the second quarter of 2014 widened compared to the second quarter of 2013, which positively impacted our refining margins. Thus far in the third quarter of 2014, discounts on most crude oils have narrowed compared to the second quarter of 2014, and we expect these discounts to remain volatile. As the end of the summer driving season approaches, we expect gasoline margins to follow the normal seasonal trend and decline from current levels. Energy markets and margins are volatile, and we expect them to continue to be volatile in the near to mid-term.
Thus far in the third quarter of 2014, ethanol margins have widened slightly. However, we expect lower average ethanol margins for the remainder of 2014 as compared to the first six months of 2014 as ethanol production is expected to increase due to the favorable ethanol margin environment.
We are exposed to volatility in the market price of biofuel credits (primarily Renewable Identification Numbers (RINs) needed to comply with the U.S. federal Renewable Fuel Standard), which we purchase in the open market to meet our obligation to blend biofuels into the products we produce. During the first six months of 2014, the market prices of RINs have been lower than the prices we experienced during 2013. We estimate that the cost of meeting our obligation for the full year of 2014 will be between $300 million and $400 million. Because the market price of RINs is volatile and is significantly impacted by biofuel blending rates that are established by the U.S. EPA, it is difficult for us to predict reliably the market price of RINs.

The following notes relate to references on pages 39 through 43.

(a) | In May 2014, we decided to abandon our Aruba Refinery, except for the associated crude oil and refined products terminal assets that we continue to operate. This transaction is more fully described in Note 3 to Condensed Notes to Consolidated Financial Statements. As a result of our decision, the results attributable to the Aruba Refinery operations have been presented as discontinued operations and the operating highlights for the refining segment and the U.S. Gulf Coast region exclude the Aruba Refinery for all periods presented.

(b) | On May 1, 2013, we completed the separation of our retail business to CST. This transaction is more fully discussed in Note 4 of Condensed Notes to Consolidated Financial Statements. As a result and effective May 1, 2013, our results of operations no longer include those of CST, except for our share of CST’s results of operations associated with the equity interest in CST retained by us at that time, which is reflected in “other income, net” in the three months ended June 30, 2013.

(c) | Throughput margin per barrel represents operating revenues less cost of sales of our refining segment divided by throughput volumes. Gross margin per gallon of production represents operating revenues less cost of sales of our ethanol segment divided by production volumes.

(d) | Other products primarily include petrochemicals, gas oils, No. 6 fuel oil, petroleum coke, sulfur, and asphalt.

(e) | The regions reflected herein contain the following refineries: the U.S. Gulf Coast region includes the Corpus Christi East, Corpus Christi West, Houston, Meraux, Port Arthur, St. Charles, Texas City, and Three Rivers Refineries; the U.S. Mid-Continent region includes the Ardmore, McKee, and Memphis Refineries; the North Atlantic region includes the Pembroke and Quebec City Refineries; and the U.S. West Coast region includes the Benicia and Wilmington Refineries.

(f) | U.S. Mid-Continent product specifications for gasoline changed on September 16, 2013 to CBOB gasoline. Therefore, average market reference prices for comparable products meeting the new specifications required in this region are provided for all periods presented.

General
Operating revenues increased $880 million (or 3 percent) in the second quarter of 2014 compared to the second quarter of 2013 primarily as a result of increased revenues from our refining segment due to an increase in both throughput volumes and refined product prices quarter over quarter in most of our regions.
43

Table of Contents
Operating income increased $280 million in the second quarter of 2014 compared to the second quarter of 2013 due primarily to a $161 million increase in refining segment operating income, a $92 million increase in ethanol segment operating income, and a $63 million decrease in general and administrative expenses, partially offset by a $39 million decrease in retail segment operating income. The reasons for these changes in the operating results of our segments and other items that affected our income are discussed below.
Refining
Refining segment operating income increased $161 million from $918 million in the second quarter of 2013 to $1.1 billion in the second quarter of 2014, due primarily to a $241 million increase in refining margin partially offset by a $58 million increase in operating expenses and a $22 million increase in depreciation and amortization expense.
Refining margin increased $241 million (a $0.58 per barrel increase) for the second quarter of 2014 compared to the second quarter of 2013 due primarily to the following:

• | Higher discounts on light sweet crude oils and sour crude oils - Because the market for refined products generally tracks the price of Brent crude oil, which is a benchmark sweet crude oil, we benefit when we process crude oils that are priced at a discount to Brent crude oil. During the second quarter of 2014, the discount in the price of light sweet crude oils and sour crude oils processed in our U.S. Gulf Coast region widened compared to the price of Brent crude oil. For example, in our U.S. Gulf Coast region, we processed LLS crude oil, a light sweet crude oil, which sold at a discount of $3.41 per barrel to Brent crude oil during the second quarter of 2014 compared to a premium of $1.78 per barrel during the second quarter of 2013, representing a favorable increase of $5.19 per barrel. Another example is Maya crude oil, which is a sour crude oil that sold at a discount of $13.95 per barrel to Brent crude oil during the second quarter of 2014 compared to a discount of $5.46 per barrel during the second quarter of 2013, representing a favorable increase of $8.49 per barrel. Therefore, the higher discounts on the light sweet crude oils and the sour crude oils we processed favorably impacted our refining margin. We estimate that the increase in the discounts for sweet crude oils and sour crude oils that we processed had a positive impact to our refining margin of approximately $170 million and $400 million, respectively, quarter over quarter.

• | Higher throughput volumes - Refining throughput volumes increased by 115,000 barrels per day in the second quarter of 2014 compared to the second quarter of 2013 due to less turnaround activity and higher utilization rates spurred by the increased availability of discounted North American light crude oils on the U.S. Gulf Coast. We estimate that the increase in refining throughput volumes had a positive impact on our refining margin of approximately $100 million for all regions quarter over quarter.

• | Decrease in gasoline margins - We experienced a decrease in gasoline margins throughout most of our regions during the second quarter of 2014 compared to the second quarter of 2013. For example, the WTI-based reference margin for U.S. Mid-Continent CBOB gasoline was $16.00 per barrel during the second quarter of 2014 compared to $26.11 per barrel during the second quarter of 2013, representing an unfavorable decrease of $10.11 per barrel. Another example is the ANS-based reference margin for U.S. West Coast CARBOB gasoline, which was $19.72 per barrel during the second quarter of 2014 compared to $21.18 per barrel during the second quarter of 2013, representing an unfavorable decrease of $1.46 per barrel. We estimate that the declines in gasoline margins per barrel during the second quarter of 2014 compared to the second quarter of 2013 had a negative impact to our refining margin of approximately $160 million.

44

Table of Contents

• | Decrease in distillate margins - We also experienced a decrease in distillate margins for most of our refining regions during the second quarter of 2014 compared to the second quarter of 2013. For example, the Brent-based reference margin for U.S. Gulf Coast ultra-low-sulfur diesel was $12.81 per barrel for the second quarter of 2014 compared to $16.79 per barrel for the second quarter of 2013 representing an unfavorable decrease of $3.98 per barrel. We estimate that the decline in distillate margins per barrel during the second quarter of 2014 compared to the second quarter of 2013 had a negative impact to our refining margin of approximately $240 million.

The increase of $58 million in operating expenses was due primarily to a $46 million increase in energy costs related to higher natural gas prices ($4.56 per MMBtu for the second quarter of 2014 compared to $4.00 per MMBtu for the second quarter of 2013) combined with higher use of natural gas due to the increase in throughput volumes.
The increase of $22 million in depreciation and amortization expense was due primarily to additional depreciation expense associated with the new hydrocracker at our St. Charles Refinery and our joint venture biofuels plant that began operating in July 2013.
Ethanol
Ethanol segment operating income was $187 million in the second quarter of 2014 compared to $95 million in the second quarter of 2013. The $92 million increase in operating income was due primarily to a $102 million increase in gross margin (a $0.39 per gallon increase), partially offset by a $9 million increase in operating expenses.
Ethanol segment gross margin per gallon increased to $1.04 per gallon in the second quarter of 2014 from $0.65 per gallon in the second quarter of 2013 due primarily to the following:

• | Lower corn prices - Corn prices decreased quarter over quarter as many of the corn-producing regions of the U.S. Mid-Continent recovered from a drought that began in 2012. For example, the Chicago Board of Trade (CBOT) corn price was $4.79 per bushel in the second quarter of 2014 compared to $6.61 per bushel in the second quarter of 2013. The decrease in the price of corn that we processed during the second quarter of 2014 favorably impacted our ethanol margin by approximately $260 million.

• | Lower ethanol prices - Ethanol prices decreased quarter over quarter as they were impacted by the decrease in corn prices. For example, the New York Harbor ethanol price was $2.43 per gallon in the second quarter of 2014 compared to $2.68 per gallon in the second quarter of 2013. The decrease in the price of ethanol per gallon during the second quarter of 2014 had an unfavorable impact to our ethanol margin of approximately $90 million.

• | Lower throughput volumes - Ethanol production volumes decreased by 232,000 gallons per day during the second quarter of 2014 compared to the second quarter of 2013 resulting from rail disruptions in the U.S. Mid-Continent that began in the first quarter of 2014 and continued into the second quarter of 2014. We estimate that the decrease in ethanol production volumes negatively impacted our ethanol gross margin by approximately $50 million quarter over quarter.

• | Lower co-product prices - The decrease in corn prices quarter over quarter had a negative effect on the prices we received for corn-related ethanol co-products, such as distillers grains and corn oil. The decrease in co-products prices had an unfavorable impact to our ethanol margin of approximately $40 million.

Corporate Expenses and Other
General and administrative expenses decreased $63 million from the second quarter of 2013 to the second quarter of 2014. This decrease was due primarily to $52 million of environmental and legal reserve adjustments and $30 million for transaction costs related to the separation of our retail business on May 1, 2013 that were recorded in the second quarter of 2013 that did not recur.
“Interest and debt expense, net of capitalized interest” for the second quarter of 2014 increased $20 million from the second quarter of 2013. This increase was due primarily to a $27 million decrease in capitalized interest due to completion of several large capital projects in the second quarter of 2013, including the new hydrocracker at our St. Charles Refinery, partially offset by a $6 million favorable impact from the decrease in average borrowings between the quarters.
Income tax expense increased $67 million from the second quarter of 2013 to the second quarter of 2014 due to higher income from continuing operations before income tax expense, partially offset by the impact of an increase in our U.S. manufacturing deduction during the second quarter of 2014 and income taxes related to the separation of CST in the second quarter of 2013 that did not recur.
“Income (loss) from discontinued operations, net of income taxes” for the second quarter of 2014 includes expenses of $59 million for an asset retirement obligation and $4 million for certain contractual obligations associated with our decision in May 2014 to abandon the Aruba Refinery, as further described in Note 3 to Condensed Notes to Consolidated Financial Statements.

The following notes relate to references on pages 47 through 51.

(a) | In May 2014, we decided to abandon our Aruba Refinery, except for the associated crude oil and refined products terminal assets that we continue to operate. This transaction is more fully described in Note 3 to Condensed Notes to Consolidated Financial Statements. As a result of our decision, the results attributable to the Aruba Refinery operations have been presented as discontinued operations and the operating highlights for the refining segment and the U.S. Gulf Coast region exclude the Aruba Refinery for all periods presented.

(b) | On May 1, 2013, we completed the separation of our retail business to CST. This transaction is more fully discussed in Note 4 of Condensed Notes to Consolidated Financial Statements. As a result and effective May 1, 2013, our results of operations no longer include those of CST, except for our share of CST’s results of operations associated with the equity interest in CST retained by us at that time, which is reflected in “other income, net” in the six months ended June 30, 2013.

(c) | Throughput margin per barrel represents operating revenues less cost of sales of our refining segment divided by throughput volumes. Gross margin per gallon of production represents operating revenues less cost of sales of our ethanol segment divided by production volumes.

(d) | Other products primarily include petrochemicals, gas oils, No. 6 fuel oil, petroleum coke, sulfur, and asphalt.

(e) | The regions reflected herein contain the following refineries: the U.S. Gulf Coast region includes the Corpus Christi East, Corpus Christi West, Houston, Meraux, Port Arthur, St. Charles, Texas City, and Three Rivers Refineries; the U.S. Mid-Continent region includes the Ardmore, McKee, and Memphis Refineries; the North Atlantic region includes the Pembroke and Quebec City Refineries; and the U.S. West Coast region includes the Benicia and Wilmington Refineries.

(f) | U.S. Mid-Continent product specifications for gasoline changed on September 16, 2013 to CBOB gasoline. Therefore, average market reference prices for comparable products meeting the new specifications required in this region are provided for all periods presented.

General
Operating revenues increased $1.1 billion (or 2 percent) in the first six months of 2014 compared to the first six months of 2013 primarily as a result of an increase in throughput volumes between the two periods related
51

Table of Contents
to our refining segment operations. In addition, operating income increased $573 million in the first six months of 2014 compared to the first six months of 2013 due primarily to a $232 million increase in refining segment operating income, a $321 million increase in ethanol segment operating income, and a $79 million decrease in general and administrative expenses, partially offset by a $81 million decrease in retail segment operating income. The reasons for these changes in the operating results of our segments and general and administrative expenses, as well as other items that affected our income, are discussed below.
Refining
Refining segment operating income increased $232 million from $2.1 billion in the first six months of 2013 to $2.4 billion in the first six months of 2014, due primarily to a $444 million increase in refining margin, partially offset by a $151 million increase in operating expenses and a $61 million increase in depreciation and amortization expense.
Refining margin increased $444 million (a $0.44 per barrel increase) in the first six months of 2014 compared to the first six months of 2013, due primarily to the following:

• | Higher discounts on light sweet crude oils and sour crude oils - Because the market for refined products generally tracks the price of Brent crude oil, which is a benchmark sweet crude oil, we benefit when we process crude oils that are priced at a discount to Brent crude oil. In the first six months of 2014, the discount in the price of light sweet crude oils compared to the price of Brent crude oil widened significantly. For example, LLS crude oil processed in our U.S. Gulf Coast region, which is a light sweet crude oil, sold at a discount of $3.15 per barrel to Brent crude oil in the first six months of 2014 compared to a premium of $2.13 per barrel in the first six months of 2013, representing a favorable increase of $5.28 per barrel. Another example is Maya crude oil, a sour crude oil, which sold at a discount of $16.20 per barrel to Brent crude oil during the first six months of 2014 compared to a discount of $7.57 per barrel during the first six months of 2013, representing a favorable increase of $8.63 per barrel. Therefore, the higher discounts on the light sweet crude oils and the sour crude oils we processed favorably impacted our refining margin. These favorable light sweet crude oil discounts in the U.S. Gulf Coast region were partially offset by the narrowing of the discount of WTI crude oil compared to Brent crude oil processed in our U.S. Mid-Continent region from $13.75 per barrel in the first six months of 2013 to $7.93 per barrel in the first six months of 2014, representing an unfavorable decrease of $5.82 per barrel. We estimate that the increase in the discounts for light sweet crude oils and sour crude oils that we processed during the first six months of 2014 had a positive impact to our refining margin of approximately $200 million and $600 million, respectively.

• | Higher throughput volumes - Refining throughput volumes increased by 125,000 barrels per day in the first six months of 2014 compared to the first six months of 2013. We estimate that the increase in refining throughput volumes had a positive impact on our refining margin of approximately $230 million.

• | Lower costs of biofuel credits - As more fully described in Note 14 of Condensed Notes to Consolidated Financial Statements, we purchase biofuel credits in order to meet our biofuel blending obligations under various government and regulatory compliance programs, and the cost of these credits (primarily RINs in the U.S.) decreased by $84 million from $267 million for the first six months of 2013 to $183 million in the first six months of 2014. This decrease was due primarily to a reduction in the market price of RINs between the two periods.

52

Table of Contents

• | Decrease in gasoline margins - We experienced a decrease in gasoline margins throughout all our regions during the first six months of 2014 compared to the first six months of 2013. For example, the Brent-based benchmark reference margin for U.S. Gulf Coast CBOB gasoline was $4.56 per barrel during the first six months of 2014 compared to $6.11 per barrel during the first six months of 2013, representing an unfavorable decrease of $1.55 per barrel. We estimate that the declines in gasoline margins per barrel during the first six months of 2014 compared to the first six months of 2013 had a negative impact to our refining margin of approximately $420 million.

• | Decrease in distillate margins - We also experienced a decrease in distillate margins for all our refining regions during the first six months of 2014 compared to the first six months of 2013. For example, the Brent-based benchmark reference margin for U.S. Gulf Coast ultra-low-sulfur diesel was $13.99 per barrel for the first six months of 2014 compared to $16.88 per barrel for the first six months of 2013, representing an unfavorable decrease of $2.89 per barrel. We estimate that the decline in distillate margins per barrel during the first six months of 2014 compared to the first six months of 2013 had a negative impact to our refining margin of approximately $330 million.

The increase of $151 million in operating expenses was due primarily to a $119 million increase in energy costs related to higher natural gas prices ($4.90 per MMBtu for the first six months of 2014 compared to $3.72 per MMBtu for the first six months of 2013) combined with higher use of natural gas due to the increase in throughput volumes.
The increase of $61 million in depreciation and amortization expense was due primarily to additional depreciation expense of $34 million associated with the new hydrocracker at our St. Charles Refinery and our joint venture biofuels plant that began operating in July 2013 and an increase in refinery turnaround and catalyst amortization expense of $12 million resulting from the completion of turnaround projects at our Texas City and Quebec City Refineries.
Ethanol
Ethanol segment operating income was $430 million for the first six months of 2014 compared to $109 million for the first six months of 2013. The $321 million increase in operating income was due primarily to a $384 million increase in gross margin (a $0.65 per gallon increase), partially offset by a $61 million increase in operating expenses.
Ethanol segment gross margin per gallon increased to $1.20 per gallon for the first six months of 2014 from $0.55 per gallon for the first six months of 2013 due primarily to the following:

• | Lower corn prices - Corn prices decreased period over period as many of the corn-producing regions of the U.S. Mid-Continent recovered from a drought that began in 2012. For example, the CBOT corn price was $4.66 per bushel for the first six months of 2014 compared to $6.94 per bushel for the first six months of 2013. The decrease in the price of corn that we processed during the first six months of 2014 favorably impacted our ethanol margin by approximately $500 million.

• | Lower co-product prices - The decrease in corn prices quarter over quarter had a negative effect on the prices we received for corn-related ethanol co-products, such as distillers grains and corn oil. The decrease in co-products prices had an unfavorable impact to our ethanol margin of approximately $80 million.

The $61 million increase in operating expenses during the first six months of 2014 compared to the first six months of 2013 was due primarily to increased energy costs and chemical costs. The increase in energy costs of $40 million was due primarily to the severe winter weather in the U.S. in the first quarter of 2014 that
53

Table of Contents
caused a significant increase in regional natural gas prices combined with higher use of natural gas due to the increase in production volumes. The increase in chemical costs of $10 million was due to higher production volumes.
Corporate Expenses and Other
General and administrative expenses decreased $79 million from the first six months of 2013 to the first six months of 2014 due primarily to $52 million of environmental and legal reserve adjustments and $30 million for transaction costs related to the separation of our retail business on May 1, 2013 that were recorded during the first six months of 2013 that did not recur.
Depreciation and amortization expense decreased $22 million due to a $20 million loss on the sale of certain corporate property in 2013 that was reflected in depreciation and amortization expense.
“Interest and debt expense, net of capitalized interest” for the first six months of 2014 increased $37 million from the first six months of 2013. This increase was due primarily to a $50 million decrease in capitalized interest due to completion of several large capital projects during the latter part of the first six months of 2014 including the new hydrocracker at our St. Charles Refinery, partially offset by a $12 million favorable impact from a decrease in average borrowings.
Income tax expense increased $156 million from the first six months of 2013 to the first six months of 2014 mainly as a result of higher income from continuing operations before income tax expense, partially offset by the impact of an increase in our U.S. manufacturing deduction during the first six months of 2014 and income taxes related to the separation of CST in the first six months of 2013 that did not recur.
“Income (loss) from discontinued operations, net of income taxes” for the six months ended June 30, 2014 includes expenses of $59 million for an asset retirement obligation and $4 million for certain contractual obligations associated with our decision in May 2014 to abandon the Aruba Refinery, as further described in Note 3 to Condensed Notes to Consolidated Financial Statements.

LIQUIDITY AND CAPITAL RESOURCES
Cash Flows for the Six Months Ended June 30, 2014 and 2013
Net cash provided by operating activities for the first six months of 2014 was $1.4 billion compared to $2.8 billion for the first six months of 2013. The decrease in net cash provided by operating activities was due primarily to the impact of an increase in accounts payable in the first six months of 2013 and a decrease in accounts payable in the first six months of 2014 resulting from a difference in the timing of the purchases of and payments for crude oil between the two periods. The changes in cash provided by or used in working capital during the first six months of 2014 and 2013 are shown in Note 12 of Condensed Notes to Consolidated Financial Statements.
The net cash provided by operating activities during the first six months of 2014, along with $812 million from available cash on hand, was used mainly to:

• | fund $1.3 billion of capital expenditures and deferred turnaround and catalyst costs;

• | make a scheduled long-term note repayment of $200 million;

• | purchase common stock for treasury of $455 million; and

• | pay common stock dividends of $266 million.

The net cash provided by operating activities during the first six months of 2013 combined with $735 million of net cash received in connection with the separation of our retail business (consisting of $550 million of proceeds on short-term debt, a $500 million cash distribution from CST less $315 million of cash retained by CST) were used mainly to:

• | fund $1.7 billion of capital expenditures and deferred turnaround and catalyst costs;

• | make scheduled long-term note repayments of $480 million;

• | purchase common stock for treasury of $560 million;

• | pay common stock dividends of $220 million; and

• | increase available cash on hand by $675 million.

Capital Investments
For 2014, we expect to incur approximately $3.0 billion for capital investments of which approximately $700 million is for deferred turnaround and catalyst costs. The capital expenditure estimate excludes expenditures related to strategic business acquisitions. We continuously evaluate our capital budget and make changes as conditions warrant.
Contractual Obligations
As of June 30, 2014, 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 six months ended June 30, 2014.
As of June 30, 2014, we had 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 $1.5 billion.

Table of Contents
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 our ratings on our senior unsecured debt are at or above investment grade level as follows:

Rating Agency |  | Rating
Moody’s Investors Service |  | Baa2 (stable outlook)
Standard & Poor’s Ratings Services |  | BBB (stable outlook)
Fitch Ratings |  | BBB (stable outlook)

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 Commercial Commitments
As of June 30, 2014, we had outstanding letters of credit under our committed lines of credit as follows (in millions):

|  | Borrowing Capacity |  | Expiration |  | Outstanding Letters of Credit
Letter of credit facilities |  | $ | 550 |  |  | June 2015 |  | $ | — |
Revolving credit facility |  | $ | 3,000 |  |  | November 2018 |  | $ | 59 |
Valero Energy Partners LP Revolver |  | $ | 300 |  |  | December 2018 |  | $ | — |
Canadian revolving credit facility |  | C$ | 50 |  |  | November 2014 |  | C$ | 10 |

As of June 30, 2014, we had no amounts borrowed under our revolving credit facilities. The letters of credit outstanding as of June 30, 2014 expire in 2014 through 2017.
Other Matters Impacting Liquidity and Capital Resources
Pension Plan Funding
We plan to contribute approximately $38 million to our pension plans and $19 million to our postretirement plans during 2014.
Stock Purchase Programs
As of June 30, 2014, we have approval under our $3 billion common stock purchase program to purchase approximately $2.3 billion of our common stock.
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, greenhouse gas 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. In addition, any major upgrades in any of our operating
56

Table of Contents
facilities could require material additional expenditures to comply with environmental laws and regulations. See Note 7 of Condensed Notes to Consolidated Financial Statements for a further discussion of our environmental matters.
Tax Matters
During the first six months of 2014, we paid approximately $400 million in tax payments that related to 2013 and that were recorded in income taxes payable as of December 31, 2013. In addition, we currently believe the cash we will pay for income taxes for 2014 will exceed amounts that we paid in 2013 and that such amounts may exceed the total income tax expense that will be reflected on our statement of income. This belief is based primarily on a decrease in deductions that we expect to claim on our U.S. federal income tax return for depreciation on our property, plant, and equipment. In prior years, the U.S. federal government enacted certain legislation that provided for the deduction of depreciation on an accelerated basis on newly built equipment as a means of encouraging capital investment by businesses. This legislation, however, generally did not extend beyond 2013. Although we expect the amount of cash required to pay our 2014 income taxes to increase compared to recent years, we believe that we will generate sufficient cash from operations and have sufficient cash on hand to make our tax payments as they become due.
The Internal Revenue Service (IRS) has ongoing tax audits related to our U.S. federal tax returns from 2002 through 2011 and we have received Revenue Agent Reports (RARs) in connection with the audits for tax years 2002 through 2009. We are vigorously contesting certain tax positions and assertions included in the RARs and we have made significant progress in resolving certain of these matters with the IRS. During the six months ended June 30, 2014, we settled the audit related to the 2004 and 2005 tax years for a group of our subsidiaries consistent with the recorded amount of uncertain tax position liabilities associated with that audit. In addition, we expect to settle our audits for tax years 2002 through 2007 within the next 12 months and we believe they will be settled for amounts that do not exceed the recorded amounts of uncertain tax position liabilities associated with those audits. As a result, we have classified a portion of our uncertain tax position liabilities as a current liability. As of June 30, 2014, the total amount of uncertain tax position liabilities, including related penalties and interest, was $437 million, with $240 million reflected as a current liability in income taxes payable and $197 million reflected in other long-term liabilities. Total uncertain tax position liabilities did not change significantly during the six months ended June 30, 2014. Should we ultimately settle for amounts consistent with our estimates, we believe that we will have sufficient cash on hand at that time to make such payments.
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 June 30, 2014, $856 million of our cash and temporary cash investments was held by our international subsidiaries.
Concentration of Customers
Our refining and marketing operations have a concentration of customers in the refining industry and customers who are refined 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
57

Table of Contents
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 POLICIES
The preparation of financial statements in conformity with U.S. generally accepted accounting principles 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 June 30, 2014, 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, 2013 was filed.

Item 3. | Quantitative 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 products (primarily gasoline and distillate), grain (primarily corn), 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 hedge:

• | 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) basis) differ from our previous year-end LIFO inventory levels and

• | forecasted feedstock and refined product purchases, refined 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 hedging and trading operations. 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 a risk control group to ensure compliance with our stated risk management policy that has been approved by our board of directors.

See Note 14 of Condensed Notes to Consolidated Financial Statements for notional volumes associated with these derivative contracts as of June 30, 2014.
COMPLIANCE PROGRAM PRICE RISK
We are exposed to market risk related to the volatility in the price of biofuel credits needed to comply with various governmental and regulatory 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. As of June 30, 2014, there was no 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 14 of Condensed Notes to Consolidated Financial Statements for a discussion about these compliance programs.

FOREIGN CURRENCY RISK
As of June 30, 2014, we had commitments to purchase $692 million of U.S. dollars. Our market risk was minimal on these contracts, as the majority of them matured on or before July 31, 2014, resulting in an immaterial gain in the third quarter of 2014.
Item 4. Controls and Procedures
