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 months ended March 31, 2013 and 2012 included in these Condensed Notes to Consolidated Financial Statements is derived from our unaudited financial statements. Operating results for the three months ended March 31, 2013 are not necessarily indicative of the results that may be expected for the year ending December 31, 2013.

The balance sheet as of December 31, 2012 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, 2012.

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.

Comprehensive Income

In February 2013, the provisions of Accounting Standards Codification (ASC) ASC Topic 220, “Comprehensive Income,” were amended to require an entity to disclose information about the amounts reclassified out of accumulated other comprehensive income by component. For amounts required to be reclassified out of accumulated other comprehensive income in their entirety in the same reporting period, the guidance requires entities to present significant amounts by the respective line items of net income, either on the face of the income statement or in the notes to the financial statements. For other amounts that are not required to be reclassified to net income in their entirety, a cross-reference is required to other disclosures that provide additional details about those amounts. These provisions are effective for interim and annual reporting periods beginning after December 15, 2012. The adoption of this guidance effective January 1, 2013 did not affect our financial position or results of operations, but did result in additional disclosures, which are included in Note 7.

Balance Sheet Offsetting Arrangements

In December 2011, the provisions of ASC Topic 210, “Balance Sheet,” were amended to require an entity to disclose information about offsetting and related arrangements to enable users of its financial statements to understand the effect of these arrangements on its financial position. In January 2013, the provisions of ASC Topic 210 were further amended to clarify that the scope of the previous amendment only applies to derivative instruments, including bifurcated derivatives, repurchase agreements and reverse repurchase agreements, and securities borrowing and securities lending transactions that are either eligible for offset in the balance sheet or are subject to an agreement similar to a master netting agreement. The guidance requires entities to disclose both gross information and net information about assets and liabilities within the scope of the amendment. These provisions are effective for interim and annual reporting periods beginning on or after January 1, 2013. The adoption of this guidance effective January 1, 2013 did not affect our financial position or results of operations, but did result in additional disclosures, which are included in Note 12.

Other

The statement of cash flows for the three months ended March 31, 2012, which was included in our Form 10-Q for the quarterly period ended March 31, 2012, reflected an incorrect classification of $160 million in proceeds on a note receivable related to the sale of our Paulsboro Refinery in December 2010. We previously reflected such proceeds as a component of cash flows from operating activities rather than as a component of cash flows from investing activities. The statement of cash flows for the three months ended March 31, 2012 included in this Form 10-Q for the quarterly period ended March 31, 2013 has been corrected to properly reflect the classification of those proceeds.
