Valero Energy's fourth-quarter profit soared on higher refining margins, as it swapped out foreign crude for cheaper domestic oil. Net income was $1.01 billion, or $1.82 per share; compared with $45 million, or 8 cents per share, a year earlier. Valero's income grew on higher refining margins because it replaced imported light crude oil with cheaper domestic crude at its Gulf Coast and Memphis refineries. It was the company's highest fourth-quarter earnings per share since 2005.
