Discontinued Operations
## Table 0 ##
For additional information regarding our discontinued operation, see Note 3 to our Consolidated Financial Statements.
Foreign Currency Exchange Rates Foreign currency exchange rates can increase or decrease profit margins and Costs applicable to sales to the extent costs are paid in foreign currencies.
Such fluctuations have not had a material impact on our revenue since gold and copper are sold throughout the world principally in U. S.  dollars.
Despite selling gold in London, we have no exposure to the euro or the British pound.
Our foreign operations sell their gold and copper production based on U. S.  dollar metal prices.
Approximately 33%, 37% and 38% of our Costs applicable to sales were paid in currencies other than the U. S.  dollar in 2016, 2015 and 2014, respectively, of which approximately 29% was denominated in the Australian dollar in the current year.
Variations in the local currency exchange rates in relation to the U. S.  dollar at our foreign mining operations decreasedd Costs applicable to sales by $2 per ounce, net of hedging losses,

Table of Contents The following performance graph is not “soliciting material,” is not deemed filed with the SEC, and is not to be incorporated by reference into any of Valero’s filings under the Securities Act of 1933 or the Securities Exchange Act of 1934, as amended, respectively.
This performance graph and the related textual information are based on historical data and are not indicative of future performance.
The following line graph compares the cumulative total return 1 on an investment in our common stock against the cumulative total return of the S&P 500 Composite Index and an index of peer companies (that we selected) for the five-year period commencing December 31, 2007 and ending December 31, 2012.
Our peer group consists of the following ten companies: Alon USA Energy, Inc. ; BP plc (BP); CVR Energy, Inc. ; Hess Corporation; HollyFrontier Corporation; Marathon Petroleum Corporation; Phillips 66 (PSX); Royal Dutch Shell plc (RDS); Tesoro Corporation; and Western Refining, Inc.  Our peer group previously included Chevron Corporation (CVX) and Exxon Mobil Corporation (XOM) but they were replaced with BP, PSX, and RDS.
In 2012, PSX became an independent downstream energy company and was added to our peer group.
CVX and XOM were replaced with BP and RDS as they were viewed as having operations that more closely aligned with our core businesses.
COMPARISON OF 5 YEAR CUMULATIVE TOTAL RETURN1 Among Valero Energy Corporation, the S&P 500 Index, Old Peer Group, and New Peer Group
## Table 2 ##
1 Assumes that an investment in Valero common stock and each index was $100 on December 31, 2007.
“Cumulative total return” is based on share price appreciation plus reinvestment of dividends from December 31, 2007 through December 31, 2012.
