Bank Debt and Credit Facilities

We have a $3 billion revolving credit facility (the Revolver) that has a maturity date of December 2016. The Revolver has certain restrictive covenants, including a maximum debt-to-capitalization ratio of 60 percent. As of June 30, 2012 and December 31, 2011, our debt-to-capitalization ratios, calculated in accordance with the terms of the Revolver, were 26 percent and 29 percent, respectively. We believe that we will remain in compliance with this covenant.

In addition to the Revolver, one of our Canadian subsidiaries has a committed revolving credit facility under which it may borrow and obtain letters of credit up to C$115 million.

During the six months ended June 30, 2012, we borrowed and repaid $1.1 billion under our Revolver. During the six months ended June 30, 2011, we had no borrowings or repayments under our Revolver. We had no borrowings or repayments under the Canadian revolving credit facility during the six months ended June 30, 2012 and 2011. As of June 30, 2012 and December 31, 2011, we had no borrowings outstanding under the Revolver or the Canadian revolving credit facility.

We had outstanding letters of credit under our committed lines of credit as follows (in millions):



				Amounts Outstanding
	Borrowing Capacity		Expiration	June 30, 2012		December 31, 2011
Letter of credit facilities	$	550	June 2013	$	300	$	300
Revolver	$	3,000	December 2016	$	70	$	119
Canadian revolving credit facility	C$	115	December 2012	C$	11	C$	20

In July 2012, one of our letter of credit facilities was amended to extend its maturity date through June 2013 and to increase its borrowing capacity by $50 million. The borrowing capacity and expiration shown in the table above reflect these changes.

As of June 30, 2012 and December 31, 2011, we had $649 million and $391 million, respectively, of letters of credit outstanding under our uncommitted short-term bank credit facilities.

Accounts Receivable Sales Facility

As of June 30, 2012, we had an accounts receivable sales facility with a group of third-party entities and financial institutions to sell on a revolving basis up to $1.0 billion of eligible trade receivables. In July 2012, we amended our agreement to increase the facility to $1.5 billion and to extend the maturity date to July 2013. 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.

Changes in the amounts outstanding under our accounts receivable sales facility were as follows (in millions):



	Six Months Ended June 30,
	2012			2011
Balance as of beginning of period	$	250		$	100
Proceeds from the sale of receivables	1,300			—
Repayments	(1,450		)	—
