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, 2015 and 2014 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, 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015.

The balance sheet as of December 31, 2014 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, 2014.

In May 2014, we abandoned our Aruba Refinery, except for the associated crude oil and refined products terminal assets that we continue to operate. As a result, the refinery’s results of operations have been presented as discontinued operations for the three and six months ended June 30, 2014. For the three and six months ended June 30, 2014, the Aruba Refinery had no operating revenues and a $63 million and $64 million loss before income tax expense, respectively, primarily related to asset retirement obligations. There was no tax benefit recognized for the loss from discontinued operations for the three and six months ended June 30, 2014 as we do not expect to realize this tax benefit.

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.

Discontinued Operations

In April 2014, the provisions of Accounting Standards Codification (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 were effective

CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

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 did 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.

New Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (FASB) 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. In July 2015, the FASB deferred the effective date of the new standard by one year. As a result, the standard is effective for annual reporting periods beginning after December 15, 2017, 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 standard, or retrospectively with a cumulative effect adjustment to retained earnings as of the date of initial application. Early adoption is permitted, but not before the original effective date, which was for annual reporting periods beginning after December 15, 2016, including interim reporting periods within those reporting periods. We are currently evaluating the effect that adopting this standard will have on our financial statements and related disclosures.

In February 2015, the provisions of ASC Topic 810, “Consolidation” were amended to improve consolidation guidance for certain types of legal entities. The guidance modifies the evaluation of whether limited partnerships and similar legal entities are variable interest entities (VIEs) or voting interest entities, eliminates the presumption that a general partner should consolidate a limited partnership, affects the consolidation analysis of reporting entities that are involved with VIEs, particularly those that have fee arrangements and related party relationships, and provides a scope exception from consolidation guidance for certain money market funds. These provisions are effective for annual reporting periods beginning after December 15, 2015, and interim periods within those annual periods, with early adoption permitted. These provisions may also be adopted retrospectively in previously issued financial statements for one or more years with a cumulative-effect adjustment to retained earnings as of the beginning of the first year restated. The adoption of this guidance effective January 1, 2016 will not affect our financial position or results of operations, but will result in additional disclosures.

In April 2015, the provisions of ASC Subtopic 835-30, “Interest–Imputation of Interest” were amended to simplify the presentation of debt issuance costs. The guidance requires that debt issuance costs related to a note be reported in the balance sheet as a direct deduction from the face amount of that note, consistent with debt discounts, and that amortization of debt issuance costs be reported as interest expense. These provisions are to be applied retrospectively and are effective for annual reporting periods beginning after December 15, 2015, and interim periods within those annual periods, with early adoption permitted. The adoption of this guidance effective January 1, 2016 will not materially affect our financial position or results of operations; however, our debt issuance costs associated with issued debt will be reported in the balance sheet as a direct deduction from “debt and capital lease obligations, less current portion” and excluded from “deferred charges and other assets, net.”

CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Also in April 2015, the provisions of ASC Topic 715, “Compensation–Retirement Benefits” were amended to provide a practical expedient for the measurement date of an entities’ defined benefit pension or other postretirement plans. For an entity with a fiscal year-end that does not coincide with a month-end, the guidance provides a practical expedient that allows the entity to measure the defined benefit plan assets and obligations using the month-end that is closest to the entity’s fiscal year-end. For an entity that has a significant event in an interim period that calls for a remeasurement, the guidance allows an entity to remeasure the defined benefit plan assets and obligations using the month-end that is closest to the date of the significant event. These provisions are effective retrospectively for annual reporting periods beginning after December 15, 2015, and interim periods within those annual periods, with early adoption permitted. The adoption of this guidance effective January 1, 2016 will not affect our financial position or results of operations.

In May 2015, the FASB amended the provisions of ASC Topic 820, “Fair Value Measurements,” to remove the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value per share practical expedient. The guidance also removes the requirement to make certain disclosures for all investments that are eligible to be measured using the net asset value per share practical expedient and limits those disclosures to investments for which the entity has elected to measure the fair value using that practical expedient. These provisions are to be applied retrospectively and are effective for annual reporting periods beginning after December 15, 2015, and interim periods within those annual periods, with early adoption permitted. The adoption of this guidance effective January 1, 2016 will not affect our financial position or results of operations, but will result in revised disclosures.

In July 2015, the provisions of ASC Topic 330, “Inventory” were amended to simplify the measurement of inventory. The guidance does not apply to inventory where the cost of such inventory is measured using the last-in, first-out (LIFO) or the retail inventory methods. The guidance applies to inventory where the cost of such inventory is measured using the first-in, first-out (FIFO) or average cost methods, and it requires the inventory to be measured at the lower of cost and net realizable value rather than the lower of cost or market. Net realizable value is defined as the estimated selling prices in the ordinary course of business, less reasonably predicable costs of completion, disposal, and transportation. These provisions are to be applied prospectively and are effective for annual reporting periods beginning after December 15, 2016, and interim periods within those annual periods, with early adoption permitted. The adoption of this guidance effective January 1, 2017 is not expected to affect our financial position or results of operations.


2.	VALERO ENERGY PARTNERS LP

Valero Energy Partners LP (VLP) is a publicly traded master limited partnership that we formed to own, operate, develop, and acquire crude oil and refined petroleum products pipelines, terminals, and other transportation and logistics assets. As of June 30, 2015, VLP’s assets included crude oil and refined products pipeline and terminal systems in the U.S. Gulf Coast and U.S. Mid-Continent regions that are integral to the operations of seven of our refineries.

Effective March 1, 2015, we contributed to VLP our Houston and St. Charles Terminal Services Business, which owns and operates crude oil, intermediates, and refined products terminals supporting our Houston and St. Charles Refineries. We received (i) cash consideration of $571 million and (ii) 1,908,100 common units representing limited partner interests in VLP and 38,941 general partner units representing general partner interests in VLP having an aggregate value of $100 million. A portion of the cash consideration was

CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

funded through a $200 million borrowing by VLP under its revolving credit facility. The remaining cash consideration was funded with $211 million of VLP’s cash on hand and a $160 million borrowing under a subordinated credit agreement between VLP and us, which is eliminated in consolidation as further described below.

The ownership of VLP consisted of the following:



	June 30, 2015		December 31, 2014
Valero:
Limited partner interest	69.6	%	68.6	%
General partner interest	2.0	%	2.0	%
Public:
Limited partner interest	28.4	%	29.4	%

We consolidate the financial statements of VLP into our financial statements and as such, VLP’s cash and temporary cash investments are included in our consolidated cash and temporary cash investments. However, VLP’s cash and temporary cash investments can be used only to settle its obligations. VLP’s cash and temporary cash investments were $52 million and $237 million as of June 30, 2015 and December 31, 2014, respectively. In addition, VLP’s partnership capital attributable to the public’s ownership interest in VLP of $381 million and $375 million as of June 30, 2015 and December 31, 2014, 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 pipeline transportation and terminaling services to us. These transactions are eliminated in consolidation.


3.	INVENTORIES

Inventories consisted of the following (in millions):



	June 30, 2015		December 31, 2014
Refinery feedstocks	$	2,600	$	2,269
Refined products and blendstocks	3,571		3,926
Ethanol feedstocks and products	206		195
Materials and supplies	241		233
Inventories	$	6,618	$	6,623

As of June 30, 2015 and December 31, 2014, the replacement cost (market value) of LIFO inventories exceeded their LIFO carrying amounts by $3.0 billion and $857 million, respectively. As of June 30, 2015 and December 31, 2014, our non-LIFO inventories accounted for $927 million and $906 million, respectively, of our total inventories.

Credit Facilities

Revolver

We have a $3 billion revolving credit facility (the Revolver) that matures in 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, 2015 and December 31, 2014, we were in compliance with the Revolver’s restrictive covenants.

VLP Revolver

VLP has a $300 million senior unsecured revolving credit facility agreement (the VLP Revolver) that matures in December 2018. The VLP Revolver is available only to the operations of VLP, and creditors of VLP do not have recourse against Valero.

Canadian Revolver

One of our Canadian subsidiaries has a C$50 million committed revolving credit facility (the Canadian Revolver) that matures in November 2015.

Activities Under Our Credit Facilities

As of June 30, 2015 and December 31, 2014, there were no borrowings outstanding under the Revolver or the Canadian Revolver.

During the six months ended June 30, 2015, VLP borrowed $200 million under the VLP Revolver in connection with VLP’s acquisition of the Houston and St. Charles Terminal Services Business, as further discussed in Note 2. The VLP Revolver bears interest at a variable rate, which was 1.4375 percent as of June 30, 2015. As of June 30, 2015, VLP had $200 million of borrowings outstanding under the VLP Revolver, but on July 1, 2015, VLP repaid $25 million on the VLP Revolver. No borrowings were outstanding on the VLP Revolver as of December 31, 2014.

Letters of Credit

Letters of credit issued under our committed credit facilities were as follows (in millions):



				Amounts Issued
	Borrowing Capacity		Expiration	June 30, 2015		December 31, 2014
Letter of credit facility	$	250	June 2015	$	—	$	56
Revolver	$	3,000	November 2018	$	63	$	54
VLP Revolver	$	300	December 2018	$	—	$	—
Canadian Revolver	C$	50	November 2015	C$	10	C$	10

In June 2015, one of our committed letter of credit facilities with a borrowing capacity of $300 million expired and was not renewed. The remaining committed letter of credit facility was amended in July 2015 to extend the maturity date to June 2016 and reduce the borrowing capacity from $250 million to $125 million.

VALERO ENERGY CORPORATION

CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

As of June 30, 2015 and December 31, 2014, there were $263 million and $80 million, respectively, of letters of credit issued under our uncommitted short-term bank credit facilities.

Non-Bank Debt

During the six months ended June 30, 2015, we issued $600 million of 3.65 percent senior notes due March 15, 2025 and $650 million of 4.9 percent senior notes due March 15, 2045. Proceeds from these debt issuances totaled $1.246 billion. We also incurred $12 million of debt issuance costs.

In addition, during the six months ended June 30, 2015, we made scheduled debt repayments of $400 million related to our 4.5 percent senior notes and $75 million related to our 8.75 percent debentures. During the six months ended June 30, 2014, we made a scheduled debt repayment of $200 million related to our 4.75 percent 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 eligible trade receivables on a revolving basis. In July 2015, we amended our agreement to decrease the facility from $1.5 billion to $1.4 billion and extended the maturity date to July 2016. 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.

As of June 30, 2015 and December 31, 2014, we had $100 million outstanding under our accounts receivable sales facility.

Capitalized Interest

Capitalized interest was $16 million and $18 million for the three months ended June 30, 2015 and 2014, respectively, and $32 million and $35 million for the six months ended June 30, 2015 and 2014, respectively.

5.	COMMITMENTS AND CONTINGENCIES

Environmental Matters

We are involved, together with several other companies, in an environmental cleanup in the Village of Hartford, Illinois (the Village) and the adjacent shutdown refinery site, which we acquired as part of an acquisition in 2005. We have been conducting initial mitigation and cleanup with other companies pursuant to an administrative order issued by the U.S. Environmental Protection Agency (EPA). The parties involved in the initial Village cleanup may have further claims between themselves for costs already incurred. In parallel with the Village cleanup, we are in litigation with the 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, the methodology for allocation of liabilities and the state of Illinois’ failure to directly sue third parties responsible for historic contamination at the site, it is reasonably possible that we could incur a loss in a range of $0 to $200 million in excess of the amount of our accrual to ultimately resolve these matters. Factors underlying this estimated range are expected to change from time to time, and actual results may vary significantly from this estimate.

Litigation Matters

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

10.	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,
	2015			2014
Decrease (increase) in current assets:
Receivables, net	$	77		$	837
Inventories	(19		)	(721		)
Income taxes receivable	79			(16		)
Prepaid expenses and other	7			11
Increase (decrease) in current liabilities:
Accounts payable	575			(707		)
Accrued expenses	(75		)	12
Taxes other than income taxes	15			(71		)
Income taxes payable	(44		)	(369		)
Changes in current assets and current liabilities	$	615		$	(1,024	)

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;


•	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, 2015 and 2014. Noncash financing activities for the six months ended June 30, 2015 included an accrual of $41 million for the purchase of 675,000 shares of our common stock, which was settled in early July 2015. 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.

11.	FAIR VALUE MEASUREMENTS

General

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

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

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


•	Level 1 - Observable inputs, such as unadjusted quoted prices in active markets for identical assets or liabilities.


•	Level 2 - Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active.

•

Level 3 - Unobservable inputs for the asset or liability. Unobservable inputs reflect our own assumptions about what market participants would use to price the asset or liability. The inputs are developed based on the best information available in the circumstances, which might include occasional market quotes or sales of similar instruments or our own financial data such as internally developed pricing models, discounted cash flow methodologies, as well as instruments for which the fair value determination requires significant judgment.

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, 2015 and December 31, 2014.

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 12, 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 12, 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 for our international operations to manage our exposure to exchange rate fluctuations on transactions

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.

•

Environmental credit obligations represent our liability for the purchase of (i) biofuel credits (primarily Renewable Identification Numbers (RINs) in the U.S.) needed to satisfy our obligation to blend biofuels into the products we produce and (ii) emission credits under the California Global Warming Solutions Act (the California cap-and-trade system, also known as AB 32) and Quebec’s Regulation respecting the cap-and-trade system for greenhouse gas emission allowances (the Quebec cap-and-trade system), collectively, the cap-and-trade systems. To the degree we are unable to blend biofuels (such as ethanol and biodiesel) at percentages required under the biofuel programs, we must purchase biofuel credits to comply with these programs. Under the cap-and-trade systems, we must purchase emission credits to comply with these systems. These programs are further described in Note 12 under “Compliance Program Price Risk.” The liability for environmental credits is based on our deficit for such credits as of the balance sheet date, if any, after considering any credits acquired or under contract, and is equal to the product of the credits deficit and the market price of these credits as of the balance sheet date. The environmental credit obligations are categorized in Level 2 of the fair value hierarchy and are measured at fair value using the market approach based on quoted prices from an independent pricing service.

There were no transfers between Level 1 and Level 2 for assets and liabilities held as of June 30, 2015 and December 31, 2014 that were measured at fair value on a recurring basis.

There was no activity during the three and six months ended June 30, 2015 and 2014 related to the fair value amounts categorized in Level 3 as of June 30, 2015 and December 31, 2014.

Nonrecurring Fair Value Measurements

There were no assets or liabilities that were measured at fair value on a nonrecurring basis as of June 30, 2015 and December 31, 2014.

Debt (excluding capital leases)	7,319		8,334		6,354		7,562

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).

12.	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 11), 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.

•

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, 2015, we had no outstanding commodity derivative instruments that were entered into as fair value hedges.

•

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, 2015, we had no outstanding commodity derivative instruments that were entered into as cash flow hedges.

•

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) feedstock and refined product inventories, (ii) forecasted feedstock and product purchases, and product sales, and (iii) fixed-price 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, 2015, 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, 2015, we had the following outstanding commodity derivative instruments that were entered into for trading purposes. The information presents the notional volume of outstanding contracts by type of instrument and year of maturity (volumes represent thousands of barrels, except those identified as natural gas contracts that are presented in billions of British thermal units).

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, 2015 or December 31, 2014, or during the three and six months ended June 30, 2015 and 2014.

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, 2015, we had commitments to purchase $574 million of U.S. dollars. These commitments matured before July 31, 2015.

Environmental Compliance Program Price Risk

We are exposed to market risk related to the volatility in the price of credits needed to comply with various governmental and regulatory environmental compliance programs.

Certain of these programs require us to blend biofuels into the products we produce, and we are subject to such programs in most of the countries in which we operate. These countries set annual quotas for the percentage of biofuels that must be blended into the motor fuels consumed in these countries. As a producer of motor fuels from petroleum, we are obligated to blend biofuels into the products we produce at a rate that is at least equal to the applicable quota. To the degree we are unable to blend at the applicable rate, we must purchase biofuel credits (primarily RINs in the U.S.). We are exposed to the volatility in the market price of these credits, and we manage that risk by purchasing biofuel credits when prices are deemed favorable. The cost of meeting our obligations under these biofuel programs was $55 million and $91 million for the three months ended June 30, 2015 and 2014, respectively, and $188 million and $183 million for the six months ended June 30, 2015 and 2014, respectively. These amounts are reflected in cost of sales.

Effective January 1, 2015, we became subject to additional requirements under greenhouse gas emission programs, including the cap-and-trade systems, as discussed in Note 11. Under these cap-and-trade systems, we purchase various greenhouse gas emission credits available on the open market. Therefore, we are exposed to the volatility in the market price of these credits. The cost to implement certain provisions of the cap-and-trade systems are significant; however, we have recovered the majority of these costs from our customers for the six months ended June 30, 2015 and expect to continue to recover the majority of these costs in the future. For the three and six months ended June 30, 2015 and 2014, the net cost of meeting our obligations under these compliance programs was immaterial.

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. We do not require any

OVERVIEW AND OUTLOOK

Overview

For the second quarter of 2015, we reported net income attributable to Valero stockholders from continuing operations of $1.4 billion, or $2.66 per share (assuming dilution), compared to $651 million, or $1.22 per share (assuming dilution), for the second quarter of 2014. The increase of $700 million was due primarily to the increase of $993 million in our operating income as shown in the table below (in millions).



	Three Months Ended June 30,
	2015			2014			Change
Operating income (loss) by business segment:
Refining	$	2,161		$	1,079		$	1,082
Ethanol	108			187			(79		)
Corporate	(191		)	(181		)	(10		)
Total	$	2,078		$	1,085		$	993

The $1.1 billion increase in refining segment operating income in the second quarter of 2015 compared to the second quarter of 2014 was due to higher margins on gasoline and other refined products (e.g., petroleum coke, propane, and sulfur) relative to Brent crude oil, partially offset by lower discounts on sour crude oils relative to Brent crude oil. In addition, lower natural gas costs in the second quarter of 2015 favorably impacted our refining segment operating income compared to the second quarter of 2014. Our ethanol segment operating income decreased $79 million in the second quarter of 2015 compared to the second quarter of 2014 due to significantly lower ethanol margins that resulted from lower ethanol prices (which were impacted by lower gasoline prices) and lower co-product prices. Corn feedstock costs declined in the second quarter of 2015 compared to the second quarter of 2014, but the decline was not as significant as the decline in ethanol prices, which resulted in lower ethanol margins.

For the first six months of 2015, we reported net income attributable to Valero stockholders from continuing operations of $2.3 billion, or $4.52 per share (assuming dilution), compared to $1.5 billion, or $2.77 per share (assuming dilution) for the first six months of 2014. The increase of $835 million was due primarily to the increase of $1.1 billion in our operating income as shown in the table below (in millions).



	Six Months Ended June 30,
	2015			2014			Change
Operating income (loss) by business segment:
Refining	$	3,802		$	2,359		$	1,443
Ethanol	120			430			(310		)
Corporate	(349		)	(353		)	4
Total	$	3,573		$	2,436		$	1,137

The $1.4 billion increase in refining segment operating income in the first six months of 2015 compared to the first six months of 2014 was due to higher margins on gasoline and other refined products (e.g., petroleum coke, propane, and sulfur) relative to Brent crude oil, partially offset by lower discounts for most sweet and sour crude oils relative to Brent crude oil. In addition, lower natural gas costs in the first six months of 2015 favorably impacted our refining segment operating income compared to the first six months of 2014. Our ethanol segment operating income decreased $310 million in the first six months 2015 compared to the first six months of 2014 due to significantly lower ethanol margins that resulted from lower ethanol prices (which

Table of Contents

were impacted by lower gasoline prices) and lower co-product prices. Corn feedstock costs declined in the first six months of 2015 compared to the first six months of 2014, but the decline was not as significant as the decline in ethanol prices, which resulted in lower ethanol margins.

Additional details and analysis of the changes in the operating income of our business segments and other components of net income attributable to Valero stockholders are provided below under “RESULTS OF OPERATIONS.”

In March 2015, we issued $600 million of 3.65 percent senior notes due March 15, 2025 and $650 million of 4.9 percent senior notes due March 15, 2045, and our consolidated subsidiary, Valero Energy Partners LP (VLP), borrowed $200 million under its revolving credit facility (the VLP Revolver), as further described in Note 4 of Condensed Notes to Consolidated Financial Statements. On July 1, 2015, VLP repaid $25 million on the VLP Revolver.

On July 13, 2015, our board of directors authorized our repurchase of an additional $2.5 billion of our outstanding common stock with no expiration date.

Outlook

Energy markets and margins were volatile during the first six months of 2015, and we expect them to continue to be volatile in the near to mid-term. Below is a summary of factors that have impacted or may impact our results of operations during the third quarter of 2015:


•	Refining margins are expected to be volatile as gasoline margins are projected to follow the seasonal trend and decline from current levels and crude oil discounts are expected to widen due to an anticipated increase in crude oil available in the market resulting from the start of the fall refinery maintenance season.


•	Ethanol margins are expected to remain depressed as long as gasoline prices remain low.


•	The market price of biofuel credits (primarily RINs) is expected to remain volatile during 2015 until final target volumes are set by the U.S. EPA.


•	A decline in market prices of crude oil and refined products may negatively impact the carrying value of our inventories.

The following notes relate to references on pages 36 through 40.

(a)


(b)	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.


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

(d)

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.

General

Operating revenues decreased $9.8 billion (or 28 percent) and cost of sales decreased $10.8 billion (or 33 percent) in the second quarter of 2015 compared to the second quarter of 2014 primarily due to a decrease in refined product prices and crude oil feedstock costs, respectively. As a result, operating income increased $993 million in the second quarter of 2015 compared to the second quarter of 2014, with refining segment operating income increasing by $1.1 billion and ethanol segment operating income decreasing by $79 million. In addition, corporate expenses increased by $10 million. The reasons for these changes in the operating results of our segments and corporate expenses, as well as other items that affected our income, are discussed below.

Refining

Refining segment operating income increased $1.1 billion from $1.1 billion in the second quarter of 2014 to $2.2 billion in the second quarter of 2015, due primarily to a $1.1 billion increase in refining margin and a $32 million decrease in operating expenses, partially offset by a $17 million increase in depreciation and amortization expense.

Table of Contents

Refining margin increased $1.1 billion (a $3.87 per barrel increase) for the second quarter of 2015 compared to the second quarter of 2014, due primarily to the following:

•

Increase in gasoline margins - We experienced an increase in gasoline margins throughout all our regions during the second quarter of 2015 compared to the second quarter of 2014. For example, the Brent-based benchmark reference margin for U.S. Gulf Coast CBOB gasoline was $12.76 per barrel during the second quarter of 2015 compared to $7.33 per barrel during the second quarter of 2014, representing a favorable increase of $5.43 per barrel. Another example is the ANS-based reference margin for U.S. West Coast CARBOB gasoline that was $30.63 per barrel during the second quarter of 2015 compared to $19.72 per barrel during the second quarter of 2014, representing a favorable increase of $10.91 per barrel. We estimate that the increase in gasoline margins per barrel during the second quarter of 2015 compared to the second quarter of 2014 had a positive impact of approximately $560 million for all refining regions.

•

Increase in other refined products margins - We experienced an increase in the margins of other refined products (such as petroleum coke and sulfur) relative to Brent crude oil during the second quarter of 2015 compared to the second quarter of 2014. Margins for other refined products were higher during the second quarter of 2015 due to the decrease in the cost of crude oils during the period compared to the second quarter of 2014. Because the market prices for our other refined products remain relatively stable, we benefit when the cost of crude oils that we process declines. For example, the benchmark price of Brent crude oil was $63.50 per barrel for the second quarter of 2015 compared to $109.74 per barrel for the second quarter of 2014. We estimate that the increase in other refined products margins during the second quarter of 2015 compared to the second quarter of 2014 had a positive impact of approximately $400 million.


•	Higher throughput volumes - Refining throughput volumes increased by 87,000 barrels per day in the second quarter of 2015 compared to the second quarter of 2014. We estimate that the increase in refining throughput volumes had a positive impact on our refining margin of approximately $110 million for all regions quarter over quarter.

•

Lower discounts on sour crude oils - Because the market prices for refined products generally track 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. For the second quarter of 2015, the discount in the price of sour crude oils narrowed compared to the price of Brent crude oil. An example is Maya crude oil, which is a sour crude oil, that sold at a discount of $8.25 per barrel to Brent crude oil during the second quarter of 2015 compared to $13.95 per barrel during the second quarter of 2014, representing an unfavorable decrease of $5.70 per barrel. We estimate that the narrowing of the discounts for sour crude oils that we processed during the second quarter of 2015 had an unfavorable impact of approximately $140 million.

The decrease of $32 million in operating expenses was primarily due to a $53 million decrease in energy costs related to lower natural gas prices ($2.69 per MMBtu for the second quarter of 2015 compared to $4.56 per MMBtu for the second quarter of 2014), partially offset by a $12 million increase in employee-related expenses primarily due to higher employee benefit costs and compensation expense.

The increase of $17 million in depreciation and amortization expense was primarily due to an increase of $15 million in refinery turnaround and catalyst amortization expense resulting from the completion of turnaround projects at many of our refineries.

Table of Contents

Ethanol

Ethanol segment operating income was $108 million in the second quarter of 2015 compared to $187 million in the second quarter of 2014. The $79 million decrease in operating income was due primarily to a $90 million decrease in gross margin (a $0.40 per gallon decrease), partially offset by an $8 million decrease in depreciation and amortization expense and a $3 million decrease in operating expenses.

Ethanol segment gross margin per gallon decreased to $0.64 per gallon in the second quarter of 2015 from $1.04 per gallon in the second quarter of 2014 due primarily to the following:

•

Lower ethanol prices - Ethanol prices were lower in the second quarter of 2015 primarily due to the decrease in crude oil and gasoline prices in the second quarter of 2015 compared to the second quarter of 2014. For example, the New York Harbor ethanol price was $1.66 per gallon in the second quarter of 2015 compared to $2.43 per gallon in the second quarter of 2014. We estimate that the decrease in the price of ethanol per gallon during the second quarter of 2015 had an unfavorable impact to our ethanol margin of approximately $210 million.


•	Lower co-product prices - The decrease in corn prices in the second quarter of 2015 compared to the second quarter of 2014 had a negative effect on the prices we received for corn-related ethanol co-products, such as distillers grains and corn oil. We estimate that the decrease in co-products prices had an unfavorable impact to our ethanol segment margin of approximately $30 million.

•

Lower corn prices - Corn prices were lower in the second quarter of 2015 compared to the second quarter of 2014 due to a higher domestic corn yield realized during the 2014 fall harvest. For example, the Chicago Board of Trade (CBOT) corn price was $3.66 per bushel in the second quarter of 2015 compared to $4.79 per bushel in the second quarter of 2014. We estimate that the decrease in the price of corn that we processed during the second quarter of 2015 favorably impacted our ethanol margin by approximately $120 million.

•

Increased production volumes - Ethanol margin was favorably impacted by increased production volumes of 517,000 gallons per day in the second quarter of 2015 compared to the second quarter of 2014, driven by lower production volumes in the second quarter of 2014 due to weather-related rail disruptions. In addition, production volumes in the second quarter of 2015 were positively impacted by production volumes from our Mount Vernon plant, which began operations in August 2014. We estimate that the increase in production volumes had a favorable impact to our ethanol margin of approximately $20 million.

Corporate Expenses and Other

General and administrative expenses increased $8 million from the second quarter of 2014 to the second quarter of 2015 primarily due to an increase in legal reserves.

“Interest and debt expense, net of capitalized interest” for the second quarter of 2015 increased $15 million from the second quarter of 2014. This increase was primarily due to $1.25 billion of debt issued by Valero and $200 million borrowed by VLP under the VLP Revolver during March 2015.

Income tax expense increased $265 million from the second quarter of 2014 to the second quarter of 2015 primarily due to $341 million of additional income tax expense as a result of higher income from continuing operations before income tax expense, partially offset by a $46 million favorable tax impact due to higher income from continuing operations from our international operations that are taxed at lower rates than in the U.S., and a $14 million increase in tax benefits from our U.S. manufacturing deduction.

Table of Contents

The loss from discontinued operations for the second quarter of 2014 includes expenses of $63 million primarily related to an asset retirement obligation associated with our decision in May 2014 to abandon the Aruba Refinery, as discussed in Note 1 to Condensed Notes to Consolidated Financial Statements.

The following notes relate to references on pages 43 through 47.


(a)	In May 2014, we abandoned our Aruba Refinery, except for the associated crude oil and refined products terminal assets that we continue to operate. As a result , the refinery’s results of 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 the six months ended June 30, 2014.


(b)	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.


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

General

Operating revenues decreased $22.1 billion (or 32 percent) and cost of sales decreased $23.2 billion (or 37 percent) in the first six months of 2015 compared to the first six months of 2014 primarily due to a decrease in refined product prices and crude oil feedstock costs, respectively. As a result, operating income increased $1.1 billion in the first six months of 2015 compared to the first six months of 2014, with refining segment operating income increasing by $1.4 billion and ethanol segment operating income decreasing by $310 million. The reasons for these changes in the operating results of our segments, as well as other items that affected our income, are discussed below.

Refining

Refining segment operating income increased $1.4 billion from $2.4 billion in the first six months of 2014 to $3.8 billion in the first six months of 2015, due primarily to a $1.4 billion increase in refining margin and a $40 million decrease in operating expenses, partially offset by a $37 million increase in depreciation and amortization expense.

Refining margin increased $1.4 billion (a $2.71 per barrel increase) in the first six months of 2015 compared to the first six months of 2014, due primarily to the following:

Increase in gasoline margins - We experienced an increase in gasoline margins throughout all our regions during the first six months of 2015 compared to the first six months of 2014. For example, the Brent-based benchmark reference margin for U.S. Gulf Coast CBOB gasoline was $10.23 per barrel during the first six months of 2015 compared to $4.56 per barrel during the first six months of 2014, representing a favorable increase of $5.67 per barrel. Another example is the ANS-based reference margin for U.S. West Coast CARBOB gasoline that was $25.02 per barrel during the first six months of 2015 compared to $14.96 per barrel during the first six months of 2014, representing a favorable increase of $10.06 per barrel. We estimate that the increase in gasoline margins per barrel during the first six months of 2015 compared to the first six months of 2014 had a positive impact of approximately $1.0 billion for all refining regions.

•

Increase in other refined products margins - We experienced an increase in the margins of other refined products (such as petroleum coke, propane, and sulfur) relative to Brent crude oil during the first six months of 2015 compared to the first six months of 2014. Margins for other refined products were higher during the first six months of 2015 due to the decrease in the cost of crude oils during the period compared to the first six months of 2014. Because the market prices for our other refined products remain relatively stable, we benefit when the cost of crude oils that we process declines. For example, the benchmark price of Brent crude oil was $59.32 per barrel for the first six months of 2015 compared to $108.82 per barrel for the first six months of 2014. We estimate that the increase in other refined products margins during the first six months of 2015 compared to the first six months of 2014 had a positive impact of approximately $840 million.

•

Lower discounts on light sweet crude oils and sour crude oils - Because the market prices for refined products generally track 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. For the first six months of 2015, the discount in the price of light sweet crude oils and sour crude oils narrowed compared to the price of Brent crude oil. For example, WTI crude oil, which is a type of light sweet crude oil, processed in our U.S. Gulf Coast region sold at a discount of $6.12 per barrel to Brent crude oil for the first six months of 2015 compared to $7.93 per barrel for the first six months of 2014, representing an unfavorable decrease of $1.81 per barrel. Another example is Maya crude oil, which is a sour crude oil, that sold at a discount of $9.63 per barrel to Brent crude oil during the first six months of 2015 compared to $16.20 per barrel during the first six months of 2014, representing an unfavorable decrease of $6.57 per barrel. We estimate that the narrowing of the discounts for light sweet crude oils and sour crude oils that we processed during the first six months of 2015 had an unfavorable impact of approximately $60 million and $490 million, respectively.


•	Higher throughput volumes - Refining throughput volumes increased by 48,000 barrels per day during the first six months of 2015 compared to the first six months of 2014. We estimate that the increase in refining throughput volumes had a positive impact on our refining margin of approximately $110 million for all regions period over period.

The decrease of $40 million in operating expenses was primarily due to a $131 million decrease in energy costs related to lower natural gas prices ($2.73 per MMBtu for the first six months of 2015 compared to $4.90 per MMBtu for the first six months of 2014). This decrease in energy costs was partially offset by the effect of $39 million of favorable sales and ad valorem tax settlements in the first six months of 2014 combined with a $22 million increase in employee-related expenses primarily due to higher employee benefit costs

Table of Contents

and compensation expense, and a $15 million increase in maintenance expense primarily related to higher levels of routine maintenance activities during the first six months of 2015.

The increase of $37 million in depreciation and amortization expense was primarily associated with the impact from new refinery capital and turnaround projects that began operating subsequent to the first six months of 2014.

Ethanol

Ethanol segment operating income was $120 million for the first six months of 2015 compared to $430 million for the first six months of 2014. The $310 million decrease in operating income was due primarily to a $329 million decrease in gross margin (a $0.67 per gallon decrease), partially offset by a $12 million decrease in operating expenses and a $7 million decrease in depreciation and amortization expense.

Ethanol segment gross margin per gallon decreased to $0.53 per gallon for the first six months of 2015 from $1.20 per gallon for the first six months of 2014 due primarily to the following:

•

Lower ethanol prices - Ethanol prices were lower in the first six months of 2015 primarily due to the decrease in crude oil and gasoline prices in the first six months of 2015 compared to the first six months of 2014. For example, the New York Harbor ethanol price was $1.59 per gallon in the first six months of 2015 compared to $2.64 per gallon in the first six months of 2014. We estimate that the decrease in the price of ethanol per gallon during the first six months of 2015 had an unfavorable impact to our ethanol margin of approximately $530 million.


•	Lower co-product prices - The decrease in corn prices in the first six months of 2015 compared to the first six months of 2014 had a negative effect on the prices we received for corn-related ethanol co-products, such as distillers grains and corn oil. We estimate that the decrease in co-products prices had an unfavorable impact to our ethanol segment margin of approximately $60 million.

•

Lower corn prices - Corn prices were lower in the first six months of 2015 compared to the first six months of 2014 due to a higher domestic corn yield realized during the 2014 fall harvest. For example, the CBOT corn price was $3.75 per bushel in the first six months of 2015 compared to $4.66 per bushel in the first six months of 2014. We estimate that the decrease in the price of corn that we processed during the first six months of 2015 favorably impacted our ethanol margin by approximately $190 million.

•

Increased production volumes - Ethanol margin was favorably impacted by increased production volumes of 599,000 gallons per day in the first six months of 2015 compared to the first six months of 2014. Production volumes in the first six months of 2014 were negatively impacted by weather-related rail disruptions. In addition, production volumes in the first six months of 2015 were positively impacted by production volumes from our Mount Vernon plant, which began operations in August 2014. We estimate that the increase in production volumes had a favorable impact to our ethanol margin of approximately $40 million.

The $12 million decrease in operating expenses was primarily due to a $35 million decrease in energy costs related to lower natural gas prices ($2.73 per MMBtu for the first six months of 2015 compared to $4.90 per MMBtu for the first six months of 2014), partially offset by an increase of $17 million related to maintenance and chemical costs due to increased production volumes.

Table of Contents

Other

“Interest and debt expense, net of capitalized interest” for the first six months of 2015 increased $16 million from the first six months of 2014. This increase was primarily due to $1.25 billion of debt issued by Valero and $200 million borrowed by VLP under the VLP Revolver during March 2015.

Income tax expense increased $286 million from the first six months of 2014 to the first six months of 2015 primarily due to $394 million of additional income tax expense as a result of higher income from continuing operations before income tax expense, partially offset by a $50 million favorable tax impact due to higher income from continuing operations from our international operations that are taxed at lower rates than in the U.S., a $12 million favorable impact related to tax audit settlements, and a $21 million increase in tax benefits from our U.S. manufacturing deduction.

The loss from discontinued operations for the six months ended June 30, 2014 includes expenses of $64 million primarily related to an asset retirement obligation associated with our decision in May 2014 to abandon the Aruba Refinery, as further described in Note 1 to Condensed Notes to Consolidated Financial Statements.

LIQUIDITY AND CAPITAL RESOURCES

Cash Flows for the Six Months Ended June 30, 2015 and 2014

Net cash provided by operating activities for the first six months of 2015 was $3.8 billion compared to $1.4 billion for the first six months of 2014. The $2.4 billion increase in net cash provided by operating activities was due primarily to a $1.6 billion favorable effect from changes in working capital between the periods and a $904 million increase in net income discussed above under “RESULTS OF OPERATIONS.” The changes in cash provided by or used for working capital during the first six months of 2015 and 2014 are shown in Note 10 of Condensed Notes to Consolidated Financial Statements.

The net cash provided by operating activities during the first six months of 2015, along with $1.45 billion in proceeds from the issuance of debt, consisting of $600 million of 3.65 percent senior notes due March 15, 2025 and $650 million of 4.9 percent senior notes due March 15, 2045 and borrowings under the VLP Revolver of $200 million as discussed in Note 4 of Condensed Notes to Consolidated Financial Statements, were used mainly to:


•	fund $1.2 billion of capital expenditures and deferred turnaround and catalyst costs;


•	make note repayments of $400 million related to our 4.5 percent senior notes, $75 million related to our 8.75 percent debentures, and $2 million related to other non-bank debt;


•	purchase common stock for treasury of $992 million;


•	pay common stock dividends of $409 million; and


•	increase available cash on hand by $2.1 billion.

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 note repayment of $200 million related to our 4.75 percent senior notes;


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


•	pay common stock dividends of $266 million.

Capital Investments

For 2015, we expect to incur approximately $1.95 billion for capital expenditures and approximately $700 million for deferred turnaround and catalyst costs. The capital expenditure estimate excludes

Table of Contents

expenditures related to potential strategic acquisitions and joint venture arrangements. We continuously evaluate our capital budget and make changes as conditions warrant.

We hold an option until January 2016 to purchase a 50 percent interest in the Diamond Pipeline project, a 440-mile, 20-inch crude oil pipeline that is projected to provide capacity of up to 200,000 barrels per day of domestic sweet crude oil from the Plains Cushing, Oklahoma terminal to our Memphis Refinery. The Diamond Pipeline project is currently being constructed by a third party for an estimated $900 million and is expected to be completed in 2017.

Contractual Obligations

As of June 30, 2015, 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, 2015.

As of June 30, 2015, 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. In June 2015, the actual availability under the facility fell below the facility borrowing capacity to $1.4 billion primarily due to a decrease in eligible trade receivables as a result of the decline in the market prices of the finished products that we produce. In July 2015, we amended our agreement to decrease the facility from $1.5 billion to $1.4 billion and extended the maturity date to July 2016.

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 the 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, 2015, letters of credit issued under our committed credit facilities were as follows (in millions):



	Borrowing Capacity		Expiration	Letters of Credit Issued
Letter of credit facility	$	250	June 2015	$	—
Revolver	$	3,000	November 2018	$	63
VLP Revolver	$	300	December 2018	$	—
Canadian Revolver	C$	50	November 2015	C$	10

Other Matters Impacting Liquidity and Capital Resources

Stock Purchase Programs

As of June 30, 2015, we had approximately $567 million of repurchase authorization remaining available under our $3 billion common stock purchase program, but we have no obligation to make purchases under this program. On July 13, 2015, our board of directors authorized our repurchase of an additional $2.5 billion of our outstanding common stock with no expiration date.

Pension Plan Funding

We plan to contribute approximately $47 million to our pension plans and $20 million to our other postretirement benefit plans during 2015. We contributed $21 million to our pension plans and $6 million to our other postretirement benefit plans during the six months ended June 30, 2015.

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 as previously discussed above in “OUTLOOK.” In addition, any major upgrades in any of our operating facilities could require material additional expenditures to comply with environmental laws and regulations. See Note 5 of Condensed Notes to Consolidated Financial Statements for a further discussion of our environmental matters.

Tax Matters

The Internal Revenue Service (IRS) has ongoing tax audits related to our U.S. federal tax returns from 2006 through 2011, and we have received Revenue Agent Reports (RARs) in connection with the audits for tax years 2006 through 2009. We are contesting certain tax positions and assertions included in the RARs and continue to make progress in resolving certain of these matters with the IRS. During the six months ended June 30, 2015, we settled the audit related to our 2004 and 2005 tax years consistent with the recorded amounts of uncertain tax position liabilities associated with those audits. In addition, we expect to settle our audits for tax years 2006 through 2007 before the end of the year, and we believe they will be settled for amounts consistent with the recorded amounts of uncertain tax position liabilities associated with those audits. Total uncertain tax position liabilities did not change significantly during the six months ended June 30, 2015. 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

Table of Contents

means other than a repatriation of earnings. As of June 30, 2015, $1.5 billion 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 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, 2015, 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, 2014 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.

Table of Contents

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.

The following sensitivity analysis includes all positions at the end of the reporting period with which we have market risk (in millions):

See Note 12 of Condensed Notes to Consolidated Financial Statements for notional volumes associated with these derivative contracts as of June 30, 2015.

COMPLIANCE PROGRAM PRICE RISK

We are exposed to market risk related to the volatility in the price of biofuel credits and greenhouse gas emission credits needed to comply with various governmental and regulatory programs. To manage these risks, we enter into contracts to purchase these credits when prices are deemed favorable. Some of these contracts are derivative instruments; however, we elect the normal purchase exception and do not record these contracts at their fair values. As of June 30, 2015, there was an immaterial amount of gain or loss in the fair value of derivative instruments that would result from a 10 percent increase or decrease in the underlying price of the contracts. See Note 12 of Condensed Notes to Consolidated Financial Statements for a discussion about these compliance programs.
