Expedia has confirmed that chief financial officer Michael Adler will leave the company after six years in his position.

However, he will remain with the company during a transition period that will include the completion of the pending spin-off of TripAdvisor.

Mark Okerstrom (pictured), currently senior vice president of corporate development, will be appointed as the company’s new chief financial officer and will assume the role after the transition period.

“Mike has been a core member of our senior executive team and a driving force in our global and product led growth strategy,” said Expedia president Dara Khosrowshahi.

“During his tenure, Mike helped drive a doubling of our GAAP earnings per share, effectively steered the company through the global financial crisis and positioned us with a rock-solid balance sheet as we approach the date of the TripAdvisor spin-off.”

Okerstrom joined Expedia in 2006, and currently leads the company’s corporate strategic planning and mergers and acquisitions functions.

Prior to joining Expedia, Okerstrom was with strategy consultancy Bain & Company in Boston and San Francisco and was also a mergers and acquisitions attorney with the global law firm of Freshfields Bruckhaus Deringer in London.

Okerstrom holds an MBA from Harvard Business School and a law degree from the University of British Columbia.
