Vicki Hollub, Occidental, CEO, transition, president

Occidental Petroleum Corp. (NYSE: OXY) said April 29 it has named Vicki A. Hollub as the Houston company's president and CEO.

The appointment completes Occidental's previously disclosed succession plan with Hollub succeeding Stephen I. Chazen.

Chazen, 69, stepped down as CEO following the company's annual shareholder meeting. He had joined Occidental in 1994 as executive vice president-corporate development. After various roles at the company, he was appointed CEO in May 2011.

Hollub, 56, has been an employee of Occidental since 1982, and most recently served as president and COO. She was also elected to the company's board of directors in 2015. She began her career in 1981 with Cities Services, which was acquired a year later by Occidental.
